1. Field of the Invention
The present invention relates generally to combination document punching and binding systems and more particularly to punching and binding systems that utilize comb-type binders.
2. Description of Related Art
Combination paper punching and binding machines are known in the art. However, most current machines that are utilized in an office environment are specifically designed for one size of paper. In the United States, the majority of machines are configured to handle only letter size (8.5″×11″) paper. In Europe, the majority of machines are configured to handle metric A4 size (8.27″×11.69″) paper. In today's business world, however, it is not uncommon for an office to routinely handle both letter size and metric A4 size paper. As such, in order to have the capability to bind stacks of both sizes of paper, separate machines are required. Although some machines are configured to handle both sizes of paper, the spacing of the punches is optimized for one size or the other. This yields a good quality bound book for one size, but not the other.
In addition, most machines that are used in an office environment cannot handle a large number of papers at one time. This is due to their compact size and limited power. The power required to punch through many sheets of paper at one time is significant because, in most machines, multiple holes are punched simultaneously. This limits the amount of paper that can be processed at one time. Although machines can be designed with increased power, increasing the power of a machine necessarily increases the size and cost of the machine.
Moreover, desktop type binding machines that also have the capability of punching the holes in the papers prior to the binding operation typically require significant operator interaction. A typical machine first requires the operator to lift the lid of the machine to the open position. The operator must find the correct size of binding element for the particular document that is about to be bound. The operator may select the “covers” setting on the machine, insert the covers into the machine, pull a lever to punch the covers, and then release the lever. The covers must then be removed from the machine. The operator may then select the “document” setting on the machine, insert the document to be bound into the machine, pull the lever to punch the document, release the lever, and then remove the document. The covers are then placed on the document. The binding element is carefully loaded by hand onto the machine so that the binding element can be opened with a lever. The covered document must be loaded onto the opened binding element, sometimes in stages if the document is too thick. Once all of the pages of the document are loaded onto the binding element, the lever may be released to close the binding element. The document is now bound.
In view of the current state of the art, the inventors have endeavored to provide a wide variety of improvements to punching and/or binding apparatus.

The apparatus 12 includes a housing 13 (shown in
The stack of paper 14 includes at least two sheets of paper (the term paper is being used herein in a very generic manner to encompass all types of material which may be bound as leafs of a book, and is not limited to pulp or fiber based materials). The term document may also be used to generically describe materials to be bound together. Thus, the terms “paper” and “document” may be used herein interchangeably and should not be construed as being limited to fiber based materials or synthetic materials, but should be construed as referring to materials to b bound together. The size of the paper may be standard letter size (8.5″×11″), metric A4 size (210 mm×297 mm), ledger size (11″×17″), or metric A3 size (297 mm×420 mm). When ledger or metric A3 sizes are used, the edges of the short sides may be oriented in the linear direction 28. For example, when a stack of paper 14 that includes ledger paper is being used in the apparatus 12, the 11″ side may be placed on the surface of the support base such that the 11″ side is oriented in the linear direction 28. It should be understood, however, that the apparatus 12 could be used or designed for use with any size paper with any edge thereof in the linear direction 28, and the ones mentioned herein are the ones most widely available.
In the embodiment shown in
As shown in
At least one embodiment of the punch drive mechanism 32 is discussed below and is illustrated in the figures. The punch driver mechanism 32 is operatively connected to a power source 34, such as an electric motor. It is also contemplated that the power source 34 may be battery powered, or may operate off of direct current or alternating current, or may be hydraulically or otherwise driven. In the illustrated embodiment, the power source 34 preferably, but not necessarily, powers the punch driver mechanism 32 continuously, such that the punch driver mechanism 32 continuously moves, as further explained below.
The punch driver mechanism 32 is operable to reciprocally drive the punch 30 through a plurality of drive strokes and a plurality of return strokes. During the drive stroke, the punch driver mechanism 32 drives the punch 30 through the edge 26 of the stack of paper 14. During the return stroke, the punch driver mechanism 32 withdraws the punch 30 from the edge 26 of the stack of paper 14. A punch cycle includes one drive stroke and one subsequent return stroke. At the end of the punch cycle, a hole 36 is formed in the edge 26 of the stack of paper 14. Also, it is contemplated that the punch 30 may be rotated like a drill so that the punch drills the stack of paper 14 rather than presses through the stack of paper 14. All references to “punching” are intended to also include “drilling,” where applicable.
The apparatus 12 further includes a power-operated translation mechanism 38 that is constructed to affect relative translational movement between the paper support base and the punch 30 in the linear direction 28. The term “translation mechanism” is a generic structural term used to describe mechanisms for translating an object, such as the punch drive mechanism, 32 in a linear direction, and is being used herein consistent with that definition. An exemplary, non-limiting embodiment of the translation mechanism 38 is discussed below. The translation mechanism 38 and the punch driver mechanism 32 are synchronized such that, when the stack of paper 14 is in the punching position, the translation mechanism 38 affects the relative translational movement between the paper support base and the punch 30 during the hole punching operation in an indexing manner, as will be discussed below.
During the hole punching operation, after each occurrence of the punch 30 being withdrawn from the stack of paper 14 on the return stroke, the translation mechanism 38 affects the relative translational movement by a predetermined distance 40 in the linear direction 28 prior to each occurrence of the punch 30 engaging the stack of paper 14 during the next punch cycle. In other words, with respect to each punch cycle, the translation mechanism 38 operates to affect this relative translational movement by the predetermined distance 40 after the time the punch 30 has withdrawn from the stack of paper 14, but before the punch 30 re-engages with the stack of paper 14. This causes the stack of paper 14 to be punched along the edge 26 such that a series of holes 36 are spaced apart essentially evenly with a pitch 42 in the linear direction 28. When there is a single punch 30, the predetermined distance 40 is equal to the pitch 42.
The synchronization of the punch driver mechanism 32 and the translation mechanism 38 may be controlled and executed in a number of ways, including but not limited to the use of servomechanisms and servomotors that may be operatively connected to a common controller that operates both the punch driver mechanism 32 and the translation mechanism 38 in a synchronized manner, such as a programmed controller. In the illustrated embodiment, a mechanical transmission gears the translation mechanism 38 to the power source 34 driving the punch driver mechanism 32, but this construction is only an example and should not be considered limiting. Additionally, although the illustrated embodiments show the translation mechanism 38 moving the punch 30 relative to a stationary paper support base, the reverse could be done and the paper support base could be moved relative to a stationary punch. Further, although the illustrated embodiment shows the punch drive mechanism 32 and the translation mechanism 38 as being housed together and sharing a common power source, they could be distinct units and use separate power sources if desired.
In at least one embodiment, the punch driver mechanism 32 also includes a flywheel 44, shown in
As shown, the elongated link 48 is operatively connected to a rotatable transfer member 54 and a disc 56 by a connecting member 58. The rotatable transfer member 54 and the disc 56 may be gears, pulleys, or any other type of rotatable member. As explained below, the disc 56 receives the force from the power source 34 through other gears constituting a transmission and provides the driving force to the punch 30 via the elongated link 48. The connecting member 58 extends from the disc 56, through the elongated link 48, and to the rotatable transfer member 54. In the illustrated embodiment, the connecting member 58 connects to the rotatable transfer member 54 and the disc 56 at connecting points 60 that are offset (i.e., eccentric) from the centers of the rotatable transfer member 54 and disc 56 (which are coaxial with the first and second portions 47, 49 of the crank shaft 46). This way, as the rotatable transfer member 54 and the second disc 56 rotate in tandem, the first end 50 of the elongated link 48 will travel circumferentially and the second end 52 will travel radially outwardly, inwardly, and outwardly as the rotatable transfer member 54 and disc 56 complete one revolution. This causes the punch piston 53 to move upward and then downward in a piston-like motion. The punch piston 53 moves upward during the drive stroke and downward during the return stroke. In
As shown in
Preferably, the rotatable transfer member 54 includes a contact portion 62 that is spaced radially from an axis about which the rotatable transfer member 54 rotates. The rotatable transfer member 54 is rotated continuously during the hole punching operation as the punch driver mechanism 32 continuously moves the punch 30 through the drive and return strokes. The function of this contact portion 62 will be discussed below in relation to the translation mechanism 38.
As illustrated in
In the illustrated embodiment, the transfer member 54 and the drive member 64 are constructed and arranged with respect to one another such that as the transfer member 54 is continuously rotated during the hole punching operation, the contact portion 62 repeatedly engages one of the engagement surfaces 66 at a point after each occurrence of the punch 30 being withdrawn from the stack of paper 14 on the return stroke to rotate the drive member 64 an amount equal to the angular spacing of the engagement surfaces 66. Then, the contact portion 62 disengages the engaged one of the engagement surfaces 66 to cease rotation of the drive member 64 at a point prior to each occurrence of the punch 30 engaging the stack of paper 14 on the subsequent drive stroke. This operation is repeated continuously with the contact portion 62 engaging the engagement surfaces 64 sequentially. This synchronizes the punch drive mechanism 32 and the translation mechanism 38.
Specifically, as mentioned above, rotating the drive member 64 in an amount equal to the angular spacing between the engagement surfaces 66 will cause the translation mechanism 38 to affect the relative translational movement between the paper support base and the punch 30 by the predetermined distance 40. By arranging the contact portion 62 and the engagement surfaces 66 with respect to one another as described, synchronization is achieved wherein the translational movement occurs only during the time period between withdrawal of the punch 30 from the stack of paper 14 and re-engagement of the punch 30 with the stack of paper 14.
Although the embodiment illustrated in
Returning to
Additional optional gears 72, 74 may also be disposed on the shaft 68. As shown, the gears 72, 74 may be attached to the shaft 68 with bushings 76, 78, which allows the gears 72, 74 to rotate independent from the rotation of the shaft 68. In the illustrated embodiment, the gears 72, 74 are both operatively connected to the rotatable member 61 that is disposed on the crank shaft 46, as explained below, and are not considered to be part of the translation mechanism 38. Instead, these gears 72, 74 are part of the transmission or drive train that couples the power source 34 to the punch drive mechanism 32, and will be discussed below. These gears 72, 74 are mounted on shaft 68 for more compact packaging, and this construction is optional and should not be considered limiting.
As shown in
The connection between the gear 70 and the first rotatable member 82 may be provided by gearing, a belt, or any other structure that provides translation from one rotating member to another rotatable member. As shown, the first rotatable member 82 includes a spur gear 86 fixed thereon and the gear 70 has axially extending splines on its peripheral edge for driving the gear 86 and hence the member 82. The second rotatable member 84 is disposed on the shaft 80 such that is may interact with other rotatable members and gears to provide additional support to the punch drive unit 19 of the apparatus 12 so that translation in the linear direction 28 is smooth, accurate, and precise.
In operation, the drive train of the illustrated embodiment drives the punch 30 in the following manner. The power source 34 and flywheel 44 are connected to the pulley 96, by a toothed belt or otherwise, so as to cause the pulley 96 to rotate. This in turn rotates the shaft 90 and the gear 92 that is disposed on the shaft 90. Rotation of the gear 92 causes rotation of the gear 74. However, because the gear 74 is disposed on the bushing 78, this rotation does not cause the shaft 68 to rotate. Rotation of the gear 74 causes rotation of the rotatable member 61 as they are also intermeshed. Similarly, because rotatable member 61 is disposed on the bushing 63, this rotation does not cause the second portion 49 of the crank shaft 46 to rotate. Rotation of the rotatable member 61 next causes rotation of the gear 72 by their intermeshing. The bushing 76 likewise does not allow the rotation of the rotatable member 61 to cause rotation of the shaft 68. Rotation of the gear 72 next causes rotation of the disc 56 by their intermeshed teeth, which then drives the elongated link 48, and, hence, the punch 30, and causes rotation of the transfer member 54, as discussed above. The members of the drive train are designed with the proper gear ratios so as to provide the punch 30 with the power needed to punch through a large stack of paper 14, yet allow for an overall compact design. By utilizing bushings and allowing gears to rotate independently of the shafts on which they are mounted, a significant amount of space is saved.
The apparatus 12 may further include a binding element retainer (not shown) that is constructed to receive the binding element 16 in an application position. In the application position, the binding element 16 extends in the linear direction 28 such that when the stack of paper 14 is in the punching position, a spine 102 of the binding element 16 is essentially parallel to the edge of the stack of paper 26 and fingers 104 of the binding element 16 are adjacent to the edge of the stack of paper.
Preferably, the spine 102 of the binding element 16 includes at least one notch 103 (shown in
Referring back to
The binding element applicator 106, the paper support base, and the binding element retainer are mounted to enable relative translational movement between the binding element applicator 106 and both the paper support base and the binding element retainer in the linear direction 28 during the binding element application operation. The binding element retainer remains fixed relative to the paper support base in the linear direction 28. It is also contemplated that the binding element applicator could be fixed and that the paper support base and the binding element retainer could be moved relative to the stationary binding element applicator.
The binding element applicator 106 is positioned relative to the paper support base and the binding element retainer such that both the leading portion 108 and trailing portions 110 are oriented essentially in the linear direction 28. When the stack of paper 14 is in the punching position and the binding element 16 is in the application position, the leading portion 108 is in alignment with the fingers 104 of the binding element 16 and spaced apart from the edge of the stack of paper 26. Also, the trailing portion 110 is oriented in the linear direction 28 immediately adjacent the edge of the stack of paper 26.
The binding element applicator 106 is configured such that, when the binding element 16 is in the application position and the stack of paper 14 is in the punching position, affecting the relative translational movement between the binding element applicator 106 and both the binding element retainer and the paper support base in the linear direction 28 such that the binding element applicator 106 travels along an entire length of the binding element 16 with the leading portion 108 leading and the trailing portion 110 trailing performs the binding element application operation in a manner to be discussed below. In the illustrated embodiment, the binding element applicator 106 is mounted to the punch drive unit 19 so that the punch drive unit 19, and particularly the translation mechanism 38 therein, will move the binding element applicator 106 in the linear direction 28 relative to the binding element retainer and the paper support base.
As can be appreciated from
Alternatively, two binding element applicators 106 may be mounted to the punch drive unit 19 on a pivoted member. In this alternative, the trailing one of the binding element applicators 106 would be pivoted down into an operative position and the leading one would be raised. In both applicator members, the leading portion 108 would be aimed towards the punch 30 and the trailing portion 110 would be aimed away. The operation could then be performed with the punch drive unit 19 traveling in one direction so that the operative, trailing binding element applicator 106 performs the binding element application operation. At the end of the punch drive unit's 19 travel, the pivoted member could be pivoted so that the other applicator member 106 is operative and the first one inoperative. This would enable a subsequent operation to be performed with the punch drive unit 19 traveling in the opposite direction, thus avoiding the need for the punch drive unit 19 to return “home” between operations.
It should be understood that the binding element applicator 106 could be entirely independent from the punch drive unit 19 and would have its own power source. Further, the use of the applicator member 106 is optional in some variations, and the structure disclosed should not be considered limiting in any way.
The apparatus 12 may further include a stop member (not shown) that is movable between a paper loading position and an operating position. When the stop member is in the loading position, it defines a stop surface that extends in the linear direction 28 and essentially perpendicularly and adjacent to the surface of the paper support base for enabling the edge 26 of the stack of paper 14 to be abutted against the stop surface so as to facilitate locating of the stack of paper 14 in the punching position with the edge 26 of the stack of paper 14 oriented in the linear direction 28 in proper relation to the punch 30 and the binding element retainer. When the stop member is in the operating position, it is disengaged from the stack of paper 14 in the punching position so as to allow the binding element applicator 106 to move along the edge 26 of the stack of paper 14 in the linear direction 28.
As an optional feature, the punch 30 is part of a removable punch device 118. The removable punch device 118 includes the punch 30, shown in
The punch mount 120 also includes a seat 126 that extends into the bore 124 and engages an end 128 of the punch 30 that is opposite a cutting end 130 thereof. The seat 126 is constructed to transmit force to the punch 30 when the punch driver mechanism 32 moves the punch device 118 through the drive stroke to punch through the stack of paper 14. The seat 126 is constructed to mechanically fail when the force being transmitted from the seat 126 to the punch 30 exceeds a predetermined threshold selected as corresponding to an overload condition in the punch driver mechanism 32.
The punch 30 may be designed such that it has a cross section that is substantially oval in shape. Other shapes are contemplated, including but not limited to rectangular, circular, and trapezoidal. In at least one embodiment, the cross section of the punch 30 is substantially a “D” shape.
The punch 30 is preferably made of a high strength steel and may include a coating to increases the hardness of the punch 30, while decreasing the friction of the punch 30. It is desirable to have a punch 30 with high hardness and low friction so that the force needed to cut through the stack of paper 14 is as low as possible. It is contemplated that a diamond like carbon (“DLC”) may be used to increase the hardness and decrease the friction of the punch 30.
As shown in
The punch device 118 may further include a flexible tube 132 that is operatively connected to the bore 124 at one end and to a paper waste container at the other end. As paper slugs are pushed into the bore 124 after each punch cycle, the paper slugs (i.e. the punched chads compressed together) enter the flexible tube 132 and are eventually emptied into the paper waste container. A small fan (not shown) may be used to create air flow to assist in moving the paper slugs from the punch device 118 to the paper waste container.
A cover 138 (shown in
Referring back to
The apparatus 12 may further include a start sequence mechanism 150. The start sequence mechanism 150 allows for the operator to initiate the punching and binding cycle. The start sequence mechanism 150 may be a button, a switch, or any other type of mechanism that allows the operator to initiate the sequence. As an optional feature, the start sequence mechanism 150 is operatively connected to an interlock device (not shown) that prevents the sequence from initiating if the door 140 to the apparatus 12 is open. Preferably, the interlock device also includes a sensor to sense whether the stack of paper 14 is present in the apparatus 12 so that if the apparatus 12 is empty, the apparatus 12 will not operate even if the apparatus 12 is on and the start sequence mechanism 150 has been activated.
As shown in
The clamp 226 may be adjusted to accommodate stacks of paper-14 of different heights. As shown in
A pair of lateral positioning structures 235 are provided to correctly position the stack of paper 14 relative to the punch drive unit 218 so that the holes 36 will be properly positioned, regardless of the size of the paper in the stack of paper 14, as further explained below.
As an optional feature, the paper support base 216 may further include a stop member (not shown) that is movable between a paper loading position and an operating position. When the stop member is in the loading position, it defines a stop surface that extends in the linear direction 28 and essentially perpendicularly and adjacent to the surface 232 of the paper support base 216 for enabling the edge 26 of the stack of paper 14 to be abutted against the stop surface so as to facilitate locating of the stack of paper 14 in the punching position with the edge 26 of the stack of paper 14 oriented in the linear direction 28. This way, when the operator loads the stack of paper 14 into the apparatus 212, the edge 26 of the stack of paper 14 is properly located with ease. The stop member may then be manually moved to the operating position so that is out of the path of the punch drive unit 218. Alternatively, the stop member may be actuated so that it is automatically moved to the operating position when the apparatus 212 is closed, or when the operator initiates the punching operating, as further explained below.
As shown in
Similar to the previous embodiment, the punch driver mechanism 242 is constructed to be operable to reciprocally drive the punch 250 through a plurality of drive strokes and a plurality of return strokes. During the drive stroke, the punch driver mechanism 242 drives the punch 250 through the edge 26 of the stack of paper 14. During the return stroke, the punch driver mechanism 242 withdrawals the punch 250 from the edge 26 of the stack of paper 14. A punch cycle is defined to include one drive stroke and one subsequent return stroke. At the end of the punch cycle, a hole 36 is formed in the edge 26 of the stack of paper 14.
The apparatus 212 further includes a translation mechanism 252, shown in
During the hole punching operation, after each occurrence of the punch 250 being withdrawn from the stack of paper 14 on the return stroke, the translation mechanism 252 affects the relative translational movement by a predetermined distance 40 in the linear direction 28 prior to each occurrence of the punch 250 engaging the stack of paper 14 during the next punch cycle. In other words, with respect to each punch cycle, the translation mechanism 252 operates to affect this relative translational movement by the predetermined distance 40 after the time the punch 250 has withdrawn from the stack of paper 14, but before the punch 250 re-engages with the stack of paper 14. This causes the stack of paper 14 to be punched along the edge 26 such that a series of holes 36 are spaced apart essentially evenly with a pitch 42 in the linear direction 28. When there is a single punch 250, the predetermined distance 40 is equal to the pitch 42.
The synchronization of the punch driver mechanism 242 and the translation mechanism 252 may be controlled and executed in a number of ways, including but not limited to the use of servomechanisms and servomotors that may be operatively connected to a common controller that operates both the punch driver mechanism 242 and the translation mechanism 252 in a synchronized manner, such as a programmed controller. In the illustrated embodiment, a mechanical transmission gears the translation mechanism 252 to the power source 238 driving the punch driver mechanism 242, but this construction is only an example and should not be considered limiting. Additionally, although the illustrated embodiments show the translation mechanism 252 moving the punch 250 relative to a stationary paper support base, the reverse could be done and the paper support base could be moved relative to a stationary punch.
In at least one embodiment, the punch drive unit 218 also includes a flywheel 240 that is driven by the power source 238, as shown in at least
In the illustrated embodiment, the flywheel 240 drives a pulley 254 with a belt (not shown). The pulley 254 is disposed outside of the cover 236 of the punch drive unit 218 and is fixedly connected to a first shaft 256 that is connected to the frame 234 and disposed inside of the cover 236. As shown in
As shown in
The elongated link 278 includes a first end 280 and a second end 282. The first end 280 is operatively connected to the connecting member 276 such that when the fourth gear 268 rotates, the second end 282 of the elongated link 278 moves in a substantially radial direction relative to the longitudinal axis of the crank shaft 272. As the fourth gear 268 and the rotatable disc 274 rotate in tandem, the first end 280 of the elongated link 278 will travel circumferentially and the second end 282 will travel radially outwardly, inwardly, and outwardly as the fourth gear 268 and the rotatable disc 274 complete one revolution.
The second end 282 of the elongated link 278 is connected to a punch piston 284 such that the punch piston 284 moves with the second end 282. Thus, as the fourth gear 268 rotates, the punch piston 284 will move upward and downward within a tube 286 that extends upward from the frame 234. The punch 250 is attached to the punch piston 284 in such a way that it may be removed from the punch piston 284 and replaced, if necessary. The punch 250 of this embodiment may be of the same design as the punch 30 of the previously described embodiment.
In at least one embodiment, the fifth gear 270 includes a contact portion 288 (shown in
As illustrated in
In this embodiment, the fifth gear 270 and the drive member 290 are constructed and arranged with respect to one another such that as the fifth gear 270 is continuously rotated during the hole punching operation, the contact portion 288 repeatedly engages one of the engagement surfaces 292 after each occurrence of the punch 250 being withdrawn from the stack of paper 14 on the return stroke to rotate the drive member 290 an amount equal to the angular spacing of the engagement surfaces 292. Then, the contact portion 288 disengages the engaged one of the engagement surfaces 292 to cease rotation of the drive member 290 prior to each occurrence of the punch 250 engaging the stack of paper 14 on the subsequent drive stroke. This operation is repeated continuously with the contact portion 288 engaging the engagement surfaces 292 sequentially. This synchronizes the punch drive mechanism 242 and the translation mechanism 252.
Specifically, as mentioned above, rotating the drive member 290 in an amount equal to the angular spacing between the engagement surfaces 292 will cause the translation mechanism 252 to affect the relative translational movement between the paper support base and the punch 250 by the predetermined distance 40. By arranging the contact portion 288 and the engagement surfaces 292 with respect to one another as described, synchronization is achieved wherein the translational movement occurs only during the time period between withdrawal of the punch 250 from the stack of paper 14 and re-engagement of the punch 30 with the stack of paper 14.
Although the embodiment illustrated in
The rotatable member 296 is operatively connected to the drive member 290 via a sixth gear 298 that is disposed about the rotatable member 296 such that when the drive member 290 rotates, the rotatable member 296 rotates about the shaft 294. Because the shaft 294 remains fixed and does not rotate, the rotation of the rotatable member 290 causes the rest of the punch drive unit 218 to move in the linear direction 28. The design of the shaft 294 and the rotatable member 296, and particularly the relative gear pitches/ratio, are such that when the drive member 290 rotates intermittently, the rotation of the rotatable member 296 causes the punch drive unit 219 of the apparatus to move a distance equal to the predetermined distance 40.
The cover 236 also functions to contain a volume of oil that provides constant lubrication to the gears and shafts that are contained within the cover 236. The bearing 258 provides a seal so that oil will not be able to leak out of the cover 236. Also, gaskets may be provided between the cover 236 and the frame 234 so that oil cannot leak at the interface between the cover 236 and the frame 234. For example,
The waste paper bin 244 may be connected to the punch 250 by way of a connector 300 that is inserted into the punch piston 284. Preferably, suction is provided such that paper waste created by the punching operation with be pulled out of the punch 250 and through the connector 300 and to the waste paper bin 244 via a flexible tube, or any other suitable structure. Also, in at least one embodiment, a hose (not shown) may be provided between a compartment that contains the power source 238 and the waste paper bin 244 such that suction may be provided by the properly configured flywheel 240. As shown, the waste paper bin 244 is sized such that it may hold a considerable amount of waste paper so that many cycles may be performed by the apparatus 212 before the waste paper bin 244 needs to be emptied, thereby minimizing operator interaction.
An air vent 302 may be disposed on the punch drive unit 218 and designed to allow air to escape the otherwise sealed punch drive unit 218, but not allow air to enter the punch drive unit 218. This way, as the punch piston 284 operates, a small vacuum will be created as the punch piston 284 moves downward within the tube 286. When the punch piston 284 moves upward within the tube 286 towards the stack of paper 14, it will displace air. The displaced air can then escape the punch drive unit 218 through the air vent 302. This allows a vacuum to be maintained within the punch drive unit 218, thereby allowing the oil contained within the cover 236 to remain within the cover 236.
The binding element applicator 220 of the apparatus 12 is shown in greater detail in
As illustrated, the binding element applicator 220 includes a binding element receiving assembly 312, shown in detail in
The first movable plate 323 also includes a plurality of angled slots 325 that are disposed on an angle relative to the first plurality of slots 324. A plurality of protrusions 327 extend through the plurality of angled slots 325 and are connected to a second movable plate (not shown) that is disposed behind the first movable plate 323 relative to the top portion 321. The second movable plate is configured to move along the direction of the first plurality of slots 324. As the second movable plate moves downward and away from the first plurality of fingers 322, the first movable plate 323 moves first towards one side of the manipulating portion 320, due to the plurality of angled slots 325. When the protrusions 327 reach the end of the angled slots 325, the first movable plate 323 travels with the second movable plate substantially downward such that the second plurality of fingers 326 move downward within the first plurality of slots 324. This movement of the second plurality of fingers 326 relative to the first plurality of fingers 322 is well known in the art, as evidenced by, for example, U.S. Pat. No. 4,872,796, which is herein incorporated by reference in its entirety.
The back plate 316 and the top portion 321 of the manipulating portion 320 may be rigidly connected to a pair of arms 328 at one end of the arms 328. Opposite ends of each arm 328 are connected to a rod 330 in such a way that if the rod 330 rotates, the arms 328 pivot. Each end of the rod 330 is operatively connected to a bearing 332 that is rigidly connected to the frame 214. A pair of stops 334 are also fixed to the frame 214 and aligned with the arms 328 such that the arms 328 are restricted from pivoting any further in that direction, as shown in
As shown in
The actuating assembly 314 further includes a second motor 350 that is supported by a bracket 352 that is connected to the frame 214. A second bracket 354 may also be used to support the second motor 350, as shown in
In operation, the binding element 16 is placed on the first plurality of fingers 322 of the binding element applicator 220 (also referred to as a binding element insertion device either term may be used interchangeably) such that the spine 102 faces away from the paper support base 216 and the fingers 104 of the binding element 16 face towards the paper support base 216 and point substantially upward. A binding element bin (not shown) may be operatively F connected to the first plurality of fingers 322 such that the binding element 16 may be placed in the bin and the binding element will be placed on the first plurality of fingers 322 in the proper orientation automatically. Once the binding element 16 is properly placed on the first plurality of fingers 322, the first motor 336 operates to cause the second plurality of fingers 326 to move over and then downward within the slots 324, thereby causing the second plurality of fingers 326 to move the fingers 104 of the binding element 16 away from the spine 102 and open the binding element 16. The second motor 350 operates to cause the binding element applicator 220 to move towards the stack of paper 14 that is supported by the paper support base 216.
The actual distance traveled by the second plurality of fingers 326 will depend on the diameter of the binding element 16 used. For example, binding elements 16 with larger diameters will require the second plurality of fingers 326 to travel further than binding elements 16 with smaller diameters. It is contemplated that a sensor (not shown) may be used to sense the size of the binding element 16 by either sensing its size directly, or sensing some other indicator on the binding element 16 itself, such as holes or notches. The sensor may then communicate a signal to the first motor 336, thereby causing the first motor 336 to operate for the appropriate amount of time. It is also contemplated that the operator of the apparatus 212 may be able to select the size of the binding element 16 by moving a switch or by programming the apparatus 212 by know procedures.
As shown in
In operation, the operator places the stack of paper 14 inside the cover 138, if a cover is desired, and places the stack of paper 14 on the paper support tray 224 of the paper support base 216 so that it abuts the stop member. The stack of paper 14 is properly positioned in the apparatus 212 and then firmly clamped into place with the clamp 226. The operator also inserts the binding element 16 of the proper size into the binding element retainer, or directly onto the binding element applicator 220. The operator closes the door 140 and initiates the punching and binding operation by contacting the start sequence mechanism 150. The stop member moves out of the way, and the punch driver unit 218 sequentially punches holes 36 at the predetermined distance 42 along the edge 26 of the stack of paper 14 until all holes are punched. The binding element applicator 220 opens the binding element 16 and moves toward the stack of paper 14. The fingers 104 of the binding element 16 are lined up with the holes 36 and inserted into the holes 36 in the stack of paper 14. The binding element applicator 220 releases the binding element 16 as it retracts away from the stack of paper 14. At the end of the operation, the operator opens the door 140 to the apparatus 12 and removes the bound book 18.
As shown in
As shown in
As part of the system 10, the fingers 104 of the binding element 16 are spaced apart at the pitch 42. Thus, the fingers 104 of the binding element 16 have a pitch of about 16.5 mm. Because a different number of holes are required between the metric A4 paper and the 8.5″×11″ letter paper, the binding element 16 may include eighteen fingers 102 for use with the metric A4 paper and seventeen fingers 102 for use with the 8.5″×11″ letter paper. It is contemplated that different indicators may be placed on the binding elements 16 to indicate paper size, as well as diameter, such that the indicators may be sensed by sensors within the apparatus, as discussed above.
Yet another embodiment of the apparatus 412 is shown in
As shown, the six punches 450 are spaced apart such that the distance between each punch 450 is a multiple of the pitch 42, as defined above. More specifically, each punch 450 is spaced apart, on center, a distance of three times the pitch 42, e.g., 49.5 mm for a 16.5 mm pitch. In this embodiment, the punch drive unit 418 moves the predetermined distance 40 between strokes, and the predetermined distance 40 equals the pitch 42.
In a configuration (not shown) where there are a plurality of punches 450 that are spaced apart at a distance, on center, equal to the pitch 42, the punch drive unit 418 would move the predetermined distance 40 between strokes, where the predetermined distance 40 would be equal to a multiple of the pitch 42. For example, in a configuration with two punches 450, the predetermined distance 40 would be equal to two times the pitch 42. In a configuration with three punches 450, the predetermined distance 40 would be equal to three times the pitch 42, and so on.
The punch drive unit 418 is configured to drive all six punches 450 at one time. As the punches 450 retract from engagement with the stack of paper 14, a translation mechanism 452 begins to move the punch drive unit 418 the predetermined distance 40. As discussed above in the previously described embodiments, the translational movement is completed before the punches 450 contact the stack of papers 14 during the next stroke. By using a plurality of punches 450, the entire operation takes less time, i.e., about one sixth of the time as compared to the previously described embodiments. Of course, additional power is needed in this embodiment to drive all six punches 450 through the stack of paper 14 at the same time. Thus, variations of the gearing shown in the previous embodiments may be modified, and the use of multiple motors may be used for driving the punches 450 individually or in sub-groups.
The apparatus 1010 comprises a frame 1020. A housing is provided to house the internal components of the apparatus 1010. The frame 1020 may have any suitable construction for mounting the various components of the apparatus 1010, and may be made from metal, any other suitable material, or any combination of materials. The frame 1020 is only shown in part and the housing is not shown at all so that the internal components of the apparatus can be clearly seen. It can be readily appreciated that the housing would be configured so as to house the internal components, yet provide access to components needed for operation. For example, the housing would have an open area on its top wall to enable the user to load the stack of documents into the document support member 1022, discussed below. Also, the housing may be removable, or have a removable or openable section, such as a lid, for enabling a user to access the internal components of the apparatus 1010. This would be desirable for periodically replacing dulled punches, or removing document segments (i.e., chads) that have been punched out from document stacks.
The document support 1022 provides a document supporting surface configured to receive the stack of documents 1016 in a punching position, shown throughout the Figures. In this punching position, the edge portion 1014 of the stack 1016 of documents extends in a longitudinal direction. The edge of the stack being punched could be either the long side, e.g., the 11 inch side in a stack of 8.5 inch×11 inch documents, or the short side, e.g., the 8.5 inch side in such a stack, and thus the term longitudinal direction does not refer to the long side of a stack, but rather refers to the direction in which the punches are arrayed. In the illustrated embodiment, the document support 1022 has two opposing walls 1024, 1026 and an edge alignment wall 28 extending between the two opposing walls 1024, 1026 in the longitudinal direction. As the illustrated embodiment is designed to be “top loading” (i.e. the stack of documents are in a generally vertical orientation when in the punching position, as illustrated), the two opposing walls 1024, 1026 extend generally vertically and the edge alignment wall 1028 extends generally horizontally. The document supporting surface in that case is defined by both the first wall 1024 and the edge alignment wall 1028. The edge alignment wall 1028 supports the stack 1016 from the bottom, and the first wall 1024 provides some support to help maintain the stack 1016 upright, as well as supporting the stack 1016 against movement in the punching direction during the punching operation.
As an optional feature, a vertical guide (not shown) may be provided. This guide would extend generally vertically above the document support 1022 to provide additional support to the document stack 1016 and help keep it upright in its generally vertical orientation. Possibly, two parallel guides could be provided for this purpose. One of the guides would preferably have its surface aligned with the surface of the first wall 1024 to ensure that the stack 1016 is properly seated against the first wall 1024.
The edge alignment wall 1028 enables an end of the edge portion 1014 to be abutted against it for aligning ends of the documents in the stack 1016 in a plane parallel to the punching and longitudinal directions. This can best be seen in
The document support 1022 further comprises a perpendicular edge alignment wall 1030 provided at a longitudinal end thereof. The wall 1030 enables a longitudinal end of the edge portion 1014 to be abutted against it for aligning the ends of the documents in the stack 1016 in a plane perpendicular to the longitudinal direction and parallel to the punching direction. This plane is defined by the surface of the perpendicular edge alignment wall 1030 against which the stack is abutted (which is vertical in the illustrated embodiment). This wall 1030 is an optional feature, but is preferred to ensure that the documents in the stack are completely aligned to provide for a quality end product. The wall 1030 may be a separate structure attached by a fastener 1032, such as a screw or bolt, or it may be formed integrally as part of the document support 1022.
Preferably, but not necessarily, the spacing between the first and second walls 1024, 1026 is selected to correspond to the maximum capacity of the apparatus 1010. That is, the spacing corresponds to the thickest stack 1016 of documents that the apparatus 1010 is designed to punch. Such a design feature is beneficial for preventing a user from putting too thick of a stack 1016 into the document support member 1052, as exceeding maximum capacity could result in the failure or fatiguing of various components of the apparatus 1010. Of course, the apparatus 1010 may be design to have any desired capacity, but for any given apparatus 1010 there will be a maximum capacity. Thus, it is desirable, but not necessary to design the spacing between the walls 1024, 1026 to limit the thickness of the stack 1016 loaded into the document support 1022. Other ways of achieving this may also be used.
In the illustrated embodiment, the second wall 1026 of the two opposing walls 1024, 1026 has a plurality of openings 1034 formed therethrough in the punching direction and facing towards the first opposing wall 1024. This is best seen in
The first wall 1024 also has a plurality of openings 1038 respectively aligned with the openings 1034 in the second wall 1026. The openings 1038 in the first wall enable the punching ends 1036 of the punches 1012 to travel entirely through the edge portion 1014 of the stack 1016. Specifically, the punching ends 1036 can enter into the openings 1038, as shown in
Preferably, but not necessarily, the openings 1038 have an internal shape matching the external shape of the punching ends 1036 of the punches 1012. This ensures that as the punching ends 1036 enter these openings 1038, the ends of the holes being formed do not become flared. Specifically, if the openings 1038 were oversized relative to the punching ends 1036, as the punching ends 1036 move through the stack 1016 and into the openings 1038, portions of the documents at the ends of the holes may be deformed slightly into the openings 1038, thus creating a slight flare. By matching the openings 1038 to the punching ends 1036, this flaring is prevented because the wall 1034 supports the portions of the documents surrounding the holes, and there is no space in the openings 1038 to accommodate the flaring.
The document support 1022 has a third wall 1040 spaced from the second wall 1026 in a direction opposite the first wall 1024. The third wall 1040 has a plurality of openings 1042 formed therethrough in the punching direction and respectively aligned with the openings 1034 formed through the second wall 1026. The punches 1012 and the openings 1042 on the third wall 1040 are arranged such that the driving ends 1044 of the punches 1012 travel through the openings 1042 as the punches 1012 are moved in the punching direction during the punching operation. Each of the openings 1042 of the third wall 1040 has an internal shape matching an external shape of the driving end 1044 of an associated punch 1012, thereby guiding the driving ends as the punches are moved in the punching direction during the punching operation. Like the openings 1034 in the second wall 1026, this configuration may also serve to prevent any deflection or off-center movement of the driving ends 1036 during the punching operation, which in turn ensures that the force applied to the punches 1012 is used effectively to drive the punches 1012 and also helps to ensure that the holes being formed are cleanly punched.
In the illustrated embodiment, the document support 1022 has a solid base 1046 and the walls 1024, 1026, and 1028 extend vertically from the base 1046 and are formed integrally therewith. Preferably, the document support 1022 is made from a rigid metal, but other suitable materials may be used.
Also, the document support 1022 and walls 1024, 1026, 1028, and 1040 may have any length in the longitudinal direction. Preferably, this length is over 11 inches, so that 8.5 in.×11 in. documents can be accommodated lengthwise. More preferably, the length is sufficient to accommodate 8.5 in.×11 in. documents lengthwise. However, any other suitable length may be used, and these examples are provided as common examples.
The illustrated document support 1022 should not be regarded as limiting and it may have any construction or configuration. For example, the document support 1022 could be oriented at an angle, so that the stack 1016 is received at an angle in an inclined orientation in its punching position. Likewise, the document support 1022 could be oriented so that the stack 1016 is oriented horizontally in its punching position. In such a horizontal orientation, only one surface would need to serve as the document supporting surface 1022, as the edge portion 1014 of the stack 1016 would be resting on the same surface which the punches will force it against. Any other variations on the document support may be practiced within the scope of the invention, and the term document support is a generic structural term intended to encompass all such structures that serve to provide support to the stack 1016 during the punching operation.
The plurality of punches 1012 are provided in a row extending in the longitudinal direction. These punches 1012 are respectively aligned with the openings 1034, 1038, and 1040, as discussed above. As mentioned above, each punch 1012 comprises a punching end 1036 and a driving end 1044. The punch end 1036 is configured to punch through the stack 1016 of documents in the punching direction, which is generally perpendicular to the longitudinal direction. This punching action forms the plurality of holes in the edge portion 1014 of the stack of documents 1016. The punching end 1036 may be made of a thin tubular metal wall and its free edge may be sharpened to facilitate penetration of the documents, which in turn reduces the amount of force that needs to be applied to the punches. The drive end 1044 may be made of a thicker tubular metal wall to facilitate receiving the driving force from the cams, as discussed below. The punching end 1036 may be welded, threaded, press-fit, or otherwise attached to the driving end 1044. Likewise, the structures could be made a one-piece unit if desired.
Each punch also has an internal bore 1048 extending therethrough from the punching end 1036 to the driving end 1044. The bore 1048 is open to the punching end 1036 for enabling document segments punched from the stack 1016 of documents to pass therethrough as the punch 1012 is driven through the edge portion of the stack of documents.
The punches 1012 are preferably equally spaced from one another so that the pitch of the holes formed in the document stack 1016 is essentially equal throughout its length. One preferred pitch is essentially 16.5 mm, as is discussed above. Another desirable pitch is essentially 25.8 mm. Although other pitches may be used, a pitch of 16.5 mm or 25.8 mm is desirable because the spacing between the opposing ends of the document stack and the punched holes will have an aesthetically pleasing appearance on both A4 and 8.5 inch×11 inch documents, particularly when the long side of the documents are punched. That is, the spacing between the punched holes at the opposing ends of the series of holes will be adequately spaced from the ends of the document stack, and the spacing will not be too far from or too close to the ends of the documents, irrespective of whether A4 or 8.5 inch×11 inch documents are used. With a 16.5 mm pitch, the long side of a stack of A4 documents would be punched with eighteen holes, and the long side of a stack of 8.5 inch×11 inch documents would be punched with seventeen holes. With a 25.8 mm pitch, the long side of a stack of A4 documents would be punched with twelve holes, and the long side of a stack of 8.5 inch×11 inch documents would be punched with eleven holes. Other pitches that are suitable for this purpose are described herein.
Other details concerning the punches 1012 will be provided after discussing the punch drive system 1050.
The punch drive system 1050 of the apparatus 1010 comprises a shaft 1052 extending in the longitudinal direction, one or more cams 1054 fixed on the shaft 1052, and a driver 1058 for selectively rotating the shaft 1052. In the illustrated embodiment, the one or more cams includes a plurality of cams 1054 fixed on the shaft 1052 in a row extending in the longitudinal direction. The number of cams 1054 corresponds to the number of punches 1012, and each cam 1054 is associated with a respective punch 1012. Each cam 1054 is positioned adjacent the driving end 1044 of its associated punch 1012. Further, each cam 1054 has a camming portion 1056 configured to apply force to its associated punch in the punching direction by engaging the driving end 1044 thereof in a camming action as the shaft 1052 is rotated. This camming action drives the punching ends 1036 of the punches through the edge portion 1014 of the stack of documents 1016 to form the plurality of holes. As can be seen best in
At least two of the cams 1054 are mounted to the shaft 1052 with their camming portions 1056 angularly offset from another such that their camming portions 1056 engage the driving ends 1044 of their associated punches 1012 in the camming action at different times during the rotation of the shaft 1052. This reduces the number of punches 1012 being driven into the stack 1016 at any one time, which in turn reduces the amount of torque that needs to be applied to the shaft 1052 to effect punching. Some of the camming portions 1056 may be angularly aligned with one another so that multiple punches 1012 are driven into the stack 1016 at the same time, but it is preferred to minimize the number of angularly aligned camming portions 1056 to reduce number of punches being driven at any one time (although some may be driven at the same time), and hence reduce the amount of torque that needs to be applied to the shaft 1052. Preferably, a majority of the cams 1054 are mounted to the shaft 1052 with their camming portions 1056 angularly offset from one another. More preferably, all the cams 1054 are mounted to the shaft 1052 with their camming portions 1056 angularly offset from one another, as is shown in the illustrated embodiment.
Whatever the arrangement of the cams 1054 and their camming portions 1056, it is desirable to provide one angular section of the row of cams 1054 where no camming portions 1056 are provided. This angular section ensures that all the punches 1012 can be withdrawn from the stack 1016 at the same time, thus allowing the stack 1016 to be removed from the document support 1022. Likewise, this will allow an unpunched stack 1016 to be placed into the document support 1022. This section can be best seen in the side view of
To key the cams 1054 onto the shaft 1052, the shaft 1052 has a polygonal cross-section and the openings in the cams 1054 have matching shapes. When the cams 1054 are received on the shaft 1052, the interface between the shaft 1052 and the cam openings will prevent rotation of the cam 1054 relative to the shaft 1052. Other ways of keying the cams 1054 onto the shaft 1052 may be used, and this example is not intended to be limiting.
As can be seen in the Figures, the shaft 1052 is rotatably supported at its axial ends on a pair of journal supports 1055. These journal supports 1055 are fixedly mounted to the frame 1020. However, any other suitable arrangement for supporting the shaft 1052 may be used.
Other arrangements of the cams 1054 may be practiced, and the illustrated embodiment is not intended to be limiting. For example, the cams 1054 could have the same general configuration, but be made wider to engage and drive multiple punches 1012 at once, thus resulting in fewer cams 1054 each associated with multiple punches 1012. Also, the shaping of these wider cams could be altered so that their camming portions 1056 are angularly offset with respect to one another, thus also resulting in fewer cams 1054, but avoiding having the same cam 1054 driving more than one punch 1012 at a time. Further, there could be one single cam associated with all the punches 1012 and having a plurality of camming portions 1056 formed thereon. Preferably, these camming portions 1056 would be angularly offset with respect to one another, as discussed above. However, for a low capacity apparatus, or one with few punches 1012, this single cam could have one continuous camming portion 1056 extending longitudinally along its length for engaging all the punches 1012. This would simplify manufacturing and assembly, although it would increase the amount of torque that needs to be applied to the shaft 1052, as all the punches 1012 would be driven at once. Other such variations may be practiced within the scope of the invention, and these alternatives are not intended to be limiting.
Preferably, the driver 1058 includes a motor 1060 coupled to the shaft 1052 for selectively rotating the shaft 1052. To increase the torque output by the motor 1060, the driver includes a reduction transmission 1062 coupling the motor 1060 to the shaft 1052. The motor 1060 is preferably electrically powered, and may be controlled by a controller (not shown). The motor 1060 may be of any type, and suitable motors 1060 are well known. Thus, specifics of the motor 1060 are not detailed in this application. The reduction transmission may also be of any type, and the one illustrated uses a variety of intermeshed gears to increase the torque being applied to the shaft 1052. Similarly to the motor 1060, suitable reduction transmissions are well known, and thus the specifics of the transmission 1062 are not detailed in this application. The choice of the motor 1060 and transmission 1062 would be determined by the amount of torque required to drive the shaft 1052 for performing the punching operation. This torque in turn is dictated by the maximum capacity of the apparatus 1010, the force required to drive each punch 1012 through a stack 1016 of that maximum capacity, and the number of punches 1012 being driven into the stack 1016 at any one time.
In the Figures, the motor 1060 and transmission 1062 are mounted on support structure 1063, which may be part of the frame 1020. However, any suitable mounting bracket or other structure may be used. For example, the support structure 1063 may be formed as a one-piece integral structure with other parts of the apparatus, such as the frame 1020, the journal supports 1055, the document support 1022, and any other structures. However, the invention is not intended to be limited in this respect to any particular construction.
As mentioned above, the motor 1060 may be controlled by a controller. This controller is preferably operates to control the motor 1060 such that the motor 1060 rotates the shaft 1052 through a single rotation during each punching operation. A single rotation ensures that all the punches 1012 are driven through the document stack 1016, but avoids the need for repeating the driving of each punch 1012. This control may be achieved in any suitable manner. For example, the shaft 1052 could be provided with a slit plate on an axial end thereof, and an optical sensor coupled to the controller could monitor the rotation of the shaft 1052 and stop rotation once a single full rotation is completed. In one embodiment, the slit plate could have a single slit that aligns with and is sensed by the optical sensor when the angular section of the cams 1054 with no camming portions 1056 is positioned adjacent the punches 1012. The controller would cease rotation of the shaft 1052 each time this single slit is encountered, thus ensuring that each punching operation includes a single full rotation of the shaft 1052, and also ensuring that the angular section with no camming portion 1056 is positioned adjacent the punches 1012 at the end of each rotation. This allows all the punches 1012 to be withdrawn from the stack 1016, thus allowing the punched stack 1016 to be removed and a new stack 1016 to be loaded into the document support 1022. Such monitoring of the shaft 1052 may also be accomplished by a Hall effect sensor, mechanical switches/contacts or any other suitable device. Likewise, instead of monitoring the shaft 1052, any gear in the transmission 1062 or the rotation of the motor 1060 could be monitored. Further, the controller could simply be designed to rotate the motor 1060 a sufficient number of times to achieve a single rotation with no positional feedback from a sensor.
The controller may be coupled to a control panel provided on the exterior of the housing. Such a control panel would have a manual switch that the user engages the signal the controller to commence the punching operation. However, any suitable way of commencing punching may be used.
In some variations of the invention, it is possible to use a manual lever or crank as the driver 1058 for effecting rotation of the shaft 1052. Such a lever or crank would preferably, but not necessarily be coupled to the shaft 1052 by a reduction transmission, such as transmission 1062 or any other suitable transmission. This alternative may have applicability to low cost, low capacity punching apparatuses 1010.
The apparatus 1010 further comprises a plurality of springs 1064 associated with the punches 1012. As can be seen in the Figures, the number of springs 1064 equals the number of punches 1012. Each spring 1064 biases an associated punch 1012 opposite the punching direction to withdraw the punches 1012 from the edge portion 1014 of the stack 16 of documents after the camming action. Specifically, as the punch 1012 is cammed and the peak of the camming portion 1056 moves past it, the associated spring 1064 will bias the punch 1012 opposite the biasing direction to withdraw it from the stack 1016. Any suitable metal or non-metal spring may be used.
In the illustrated embodiment, the driving end 1044 of each punch 1012 is wider than the punching end 1036 to define a shoulder 1066 therebetween (see
As can be seen best in
In the illustrated punch 1012, the spaced apart walls 1070 define a pair of such openings 1068 facing to opposing sides of the punch 1012, thus providing a pair of relief openings 1068 for each punch 1012. However, the punch 1012 could have only a single relief opening 1068. Other variations on the construction of this relief opening can be used. For example, the driving end 1044 could be closed off, and the relief opening could be provided as a bore in the side of the punch 1012 that communicates with the bore 1048. Preferably, a contour inside the bore 1048 would be provided to urge the segments laterally out from that relief opening. Thus, the relief opening in this alternative would not interface with the cam portion 1056. However, the illustrated construction with spaced apart walls 1070 does have the advantage of using the contour of the camming portion 1056 to facilitate discharge of the punched document segments (i.e., chads). Specifically, as the segments reach the driving end 1044 of the punch 1012 and contact the surface of the camming portion 1056, the contour of the camming portion 1056 will urge the segments to move laterally out of one of the openings 1068. Generally, the document segments will be urged in the direction the cam 1054 is rotating, as the sloped surface of the camming portion 1056 facing in that direction is the surface that is engaged with the driving end 1044 as the punching end 1036 is being driven through the stack 1016. It is during this time that the document segments are advanced through the bore 1048, because the new segments being punched will displace the segments already received in the bore and force them towards the driving end 1044. This avoids the manufacturing challenge associated with providing a contour inside the bore 1048, but it is still within the scope of the invention to use such a construction.
By providing the relief opening 1068 for each punch 1012, the invention achieves the significant advantage of enabling punches with internal bores to be used in the context of a cam-driven punching apparatus. The relief opening 1068 allows each camming portion 1056 to engage the driving end 1044 of its associated punch 1012 without interfering with the ability of the punched document segments to exit from the internal bore 1048 as the punch 1012 is being driven through the stack of documents 1016. This is beneficial because, generally, the punched segments in the bore 1048 are tightly compressed and it is only during the time that the punch 1012 is being driven that these segments are moved through the bore 1048 by the entering of new ones via the open end of the punching end 1036. Thus, providing the relief opening 1068 allows the punched segments at the driving end 1044 to exit the bore 1048, so that the newly punched segments can enter at the punching end 1036. This allows the punching apparatus 1010 to punch through a stack of documents with a lower force while still using a cam-driven construction.
As another alternative, a wider bore (not shown) could provided in the driving end 1044 in direct alignment with the bore 1048 in which the punched segments are tightly compressed. As the punched segments are passed into this wider bore, they will no longer be tightly compressed against the interior surface of a bore, and can more easily exit from the punch 1012. Such a wider bore would also be considered a relief opening. Although this approach could be used in other contexts, this would be better applied to an apparatus where the stack is received horizontally or at an inclined angle, as then the punches 1012 may be oriented with this wider bore facing at least partly downwardly to allow the segments received in the wider bore to just fall out by gravity as the camming portion 1056 disengages the driving end 1044.
In some constructions, a beneficial feature would be to provide a device for neatly collecting the punched segments discharged from the relief opening. For example, such a device could be a removable tray disposed vertically beneath the punches 1012. In such a construction, the user could just pull the tray out from the housing and empty the same periodically. Likewise, a sloped surface could be provided underneath the punches 1012 to receive the discharged segments and guide them to a collection area or tray at the side of the apparatus where they can be discarded periodically by the user. Any suitable device for managing the punched segments may be used, and the invention is not intended to be limited in this respect.
For example, a mechanical sweeper could be used to push the punched segments out towards the side of the machine, where an easily accessible receptacle may be located. Such a sweeper may be mechanically linked to the shaft 1052 so as to push the punched segments once per rotation of the shaft 1052. Instead of providing a receptacle for receiving the punched segments, a clear window could be provided on the side of the apparatus so the user can see the punched segments, and tell when the segments need to be removed. Also, a “breakaway” door could be used at the side of the apparatus, and it would push open when the punched segments pile up against it and the action of the sweeper applies enough force to open the door. Further, a sensor, such as an optical sensor or mechanical sensor, could be used to determine when the punched segments have collected above a certain level. This sensor could be used with a sweeper, or without it. Other variations are possible, and the use of such devices for managing the punched segments is not necessary.
As yet another alternative, the relief openings could be provided on the camming portions 1056 of the cams 1054.
In the embodiment of
As mentioned above, the punching apparatus 1010 includes an optional a binding apparatus 1018. This binding apparatus 1018 is constructed to open and apply a binding element (not shown) having an elongated spine and a plurality of fingers to the edge portion 1014 of the document stack 1016 after punching the edge portion 1014. Such a binding element may, for example, be a comb binding element with resilient fingers spaced at pitch essentially equal to the pitch of the punched holes, it may be binding element with relative rigid fingers that snap together at their ends, or it may have any other construction or configuration. Suitable binding apparatuses 1018 are well known for accomplishing this function, and any suitable power-operated or manually driven type may be used.
The fingers of such a binding element would have a pitch essentially matching the pitch of the punched holes. Thus, as discussed above, a binding element having fingers with a pitch of essentially 16.5 mm would be used to bind a stack of documents punched with holes at a pitch of essentially 16.5 mm. Likewise, a binding element having fingers with a pitch of essentially 25.8 mm would be used to bind a stack of documents punched with holes at a pitch of essentially 25.8 mm. The resulting product would be a bound book comprising (a) a stack of documents having a series of holes punched through an edge thereof, the series of holes being spaced apart at the appropriate pitch, and (b) a binding element comprising an elongated spine and a series of fingers spaced apart essentially evenly in the longitudinal direction of the spine with a matching pitch, the fingers extending into and through the holes in the edge of the stack to bind the stack of documents together. The pitch may be the 16.5 mm or 25.8 mm pitch mentioned above, or any other pitch, such as those described hereinbelow.
Other binding elements, such as spiral, wire, double loop wire, etc., may be used to secure documents together. Such binding elements may be applied manually, or using an apparatus, such as apparatus 1018.
The housing described above may also be constructed to conceal various components of the binding apparatus 1018, yet have open areas for loading of the document and the binding element. This is not necessary, but any suitable construction may be used.
As an optional feature, a clamp or other device may grasp the punched stack of paper and move the same into an operative position in the binding apparatus 1018. In this operative position, the stack would be positioned in the binding apparatus for receipt of the bonding element. Such a clamp or other device is beneficial to avoid the need for the user to handle the punched stack when moving it to the binding apparatus 1018. As mentioned above, this feature is optional and not necessary.
The punching mechanism 2018 includes a punch receiving block 2023 that receives a plurality of punches 2024, each of which is operatively connected to a common shaft 2026 via a cam 2028, as shown in
Returning to
The punching mechanism 2018 is discussed in greater detail above in regard to the embodiment of the apparatus 1010 illustrated in
As shown in
In the illustrated embodiment, the first plate 2040 is operatively connected to the second plate 2042 via a plurality of posts 2044 that are disposed substantially at the corners of the plates 2040, 2042. Each post 2044 includes a head 2046 and a body portion 2048 that is connected to the head 2046 (best seen in
As shown in
As shown in
Each cam 2058 is also operatively connected to the second plate 2042 near an edge 2066 thereof. As shown, a spacer 2068 is provided on the second plate 2042 near each edge 2066. The biasing of the springs 2050 located on the posts 2044 push the first plate 2040 towards the second plate 2042, causing the cams 2058 to contact the spacers 2066. Upon rotation, the eccentricity of the cams 2058 pushes the first plate 2040 away from the second plate 2042 to open the paper clamp 2020. To close the paper clamp 2020, the cams 2058 may be rotated back (or rotated further past the peak of their eccentricity) so that the springs 2050 can force the first plate 2040 back towards the second plate 2042. This will clamp a stack 2012 received between the two plates 2040, 2042.
As shown in
As shown in
Moreover, the functionalities of sensor 2057 and sensor 2061 may be combined into a single sensor that monitors relative movement of the plates 2040, 2042.
As shown in
Also shown in
As shown in
An optional paper sensor (not shown) may be constructed and arranged to sense whether or not the papers 2012 have been inserted into the paper clamp 2020. The paper sensor may be in communication with the controller 2170 so that the controller 2170 may execute certain programs, based on what condition is sensed, as will be explained in more detail below. The paper sensor is preferably an optical sensor, by may be a contact switch, or any type of sensor that is configured to sense the presence of the papers 2012.
Generally, the paper clamp 2020 may have any construction or configuration, and the illustrated construction is not intended to be limiting. For example, other mechanisms may be used to move the paper clamp 2020 parallel to the first axis 2038, other mechanisms may be used to move the plates 2040, 2042 relative to one another, or other types of sensors may be used to detect the thickness of the stack of papers 2012 or the presence of the stack of papers 2012 in the clamp 2020, or such sensors may even be eliminated. Also, limit switches may also be used to sense the position of the paper clamp 2020 relative to, for example, the supports 2034 and base 2016.
The binding element insertion device 2022 is shown in greater detail in
The binding element loading device 2084 also includes a pusher 2088 that moves relative to the support 2086. At least one plunger 2090 (two are shown in the figures) biases the pusher 2088 in a direction toward the first axis 2038. The plunger 2090 includes a spring, or any other type of resilient member, for providing a suitable biasing force. The pusher 2088 includes a recessed portion 2092 that is configured to be engaged by a person's hand. This way, when loading a binding element 2014 into the binding element loading device 2084, the user may pull the pusher 2088 away from wall 2094 against the bias of the plungers 2090 via the recessed portion 2092, insert the binding element 2014, and release the pusher 2088. The pusher 2088 then pushes the binding element 2014 against the wall 2094 that extends upward from the base 2082.
As shown in
As shown in
The entire binding element insertion device 2022 is movable relative to the base 2016 of the apparatus 2010 along a second axis 2102. In the illustrated embodiment, the second axis 2102 is substantially parallel to the base 2016 and is substantially perpendicular to the first axis 2038. As shown in
The binding element insertion device 2022 also includes a plurality of finger pullers 2110 that are disposed adjacent to the plurality of slots 2096 in the wall 2094 on a side of the wall 2094 that faces the paper clamp 2020. The plurality of finger pullers 2110 are constructed and arranged to engage the plurality of fingers 2098 of the binding element 2014 and extend the fingers 2098 away from the spine 2100 so as to “open” the binding element 2014. The plurality of finger pullers 2110 are connected to a single puller plate 2112 so that the finger pullers 2110 all move together.
As shown in
As shown in
Similarly, a “medium” binding element 2138 is shown in
c shows an embodiment of a “small” binding element 2142. As illustrated, the small binding element 2142 does not have a notch. This way, when the small binding element 2142 is inserted into the binding element loading device 2084, both the first switch 2132 and the second switch 2133 are depressed. The depression of both switches 2132, 2133 indicates that the binding element 2014 that has been inserted into the binding element insertion device 2022 is a small binding element 2142, the significance of which will be described in further detail below. Thus, not only does the sensor 2130 sense what size of binding element 2014 has been inserted, it senses whether a binding element 2014 has been inserted at all.
Of course, the sensor 2130 may be configured to sense more or less than three different binding element sizes. The three binding element sizes discussed above are but one example and are not intended to be limiting in any way. For example, the sensor 2130 may be configured to sense four or more different sizes of binding elements. Other sensors, such as bar code, optical, or other types of sensors could be used. The illustrated sensor should not be regarded as limiting.
The binding elements 2014 themselves may each be labeled with an indicator I, or mark, that gives some indication to the user as to what size it is, such as a graphical indicator, as shown in
As shown in
Other structures for ensuring proper loading of the binding element 2014 may be used and the illustrated embodiment should not be regarded as limiting.
In order to accommodate all three sizes of binding elements 2134, 2138, 2142, the binding element insertion device 2022 interacts with the controller 2170. Once the size of the binding element 2014 has been sensed, the controller 2170 determines how far the finger pullers 2110 should move to fully open the binding element 2014. Also, the movement of the binding element insertion device along the second axis 2102 relative to the paper clamp 2020, and the first axis 2038, is also dependent on the detected size of the binding element 2014. For example, if the binding element 2014 is the large binding element 2134, the controller 2170 will signal the motor 2116 to move the finger pullers 2110 a longer distance than if the binding element 2014 is the small binding element 2142, because the fingers 2098 of the large binding element 2134 are longer than the fingers 2098 of the small binding element 2142 and more movement is needed to fully open the large binding element 2134. Similarly, as will become more apparent below, the binding element insertion device 2022 will not have to move as far when moving along the second axis 2102 toward the paper clamp 2020 when the large binding element 2134 is used. Thus, the controller 2170 will use the information received from the sensor 2130 to control the two motors 2116, 2108 that affect the opening of the binding element 2014 and the positioning of the binding element 2014 with respect to the papers 2012 to be bound.
Generally, the binding element insertion device 2022 may have any construction or configuration and the construction illustrated is not intended to be limiting. Instead, the term “binding element insertion device” may be regarded as a generic structural term to describe a mechanism that insert the fingers of a binding element into the punched holes in a stack of documents. For example, the binding element insertion device may use a different mechanism for engaging and opening the fingers, a different binding element pusher (or it may be omitted), or different sensors for detecting the size of the binding element (or no sensors may be used at all).
One embodiment of the apparatus 2010 with a cover 2150 is shown in
Also shown in
The user interface 2160 is in communication with the controller 2170, as shown schematically in
When the user would like to bind a stack of papers 2012 together with a binding element 2014, the user starts by opening the lid 2152 of the apparatus 2010. The paper clamp 2020 is already in an open position, and the user places the papers 2012 in the paper clamp 2020 and ensures that the papers 2012 are properly aligned with each other in the stack. The paper sensor senses the presence of the papers 2012 and sends a signal to the controller 2170 so that the controller 2170 will be ready to send a signal to the motor 2062. The user may press the button 2164 at the user interface 2160 to indicate that the user is ready to proceed with the binding operation. The depression of the button 2164 sends a signal to the controller 2170, which signals the motor 2062 to rotate the gear 2064 so that the cams 2058 rotate and allow the first plate 2040 to move towards the second plate 2042. As the first plate 2040 moves toward the second plate 2042 to clamp the stack of papers 2012, the thickness sensor 2061 senses the thickness of the stack of papers 2012, and sends a signal to the controller 2170. The controller 2170 sends a signal to the user interface 2160 so that an indicator 2162 may tell the user what size binding element 2014, e.g. small 2142, medium 2138, or large 2134, to insert into the apparatus 2010. The user chooses the correct binding element 2014, opens the lid 2154, pulls back the pusher 2088, and inserts the binding element 2014 into the binding element loading device 2084. The users releases the pusher 2088, and if the binding element 2014 has been inserted with the proper orientation, the pusher 2088 will push the plurality of fingers 2098 through the plurality of slots 2096 in the wall 2094. The sensor 2130 senses which size binding element 2014 has been inserted, and compares the sensed size to the size that was signaled to the user. If these sizes are not the same, an error message is sent to the user interface 2160 at the error indicator 2166, thereby alerting the user that a binding element 2014 of the wrong size has been inserted into the apparatus 2010. The apparatus 2010 will not operate until a binding element 2014 of the correct size has been inserted, in the correct orientation, into the binding element loading device 2084.
When the binding element 2014 of the correct size for the thickness of the stack of papers 2012 being held by the paper clamp 2020 has been properly loaded, the controller 2170 sends a signal to the user interface 2160 that tells the user to close the lids 2152, 2154 of the apparatus 2010. As an optional feature, once the lids 2152, 2154 have been closed, interlocks actuate so that the lids 2152, 2154 cannot be opened until either the binding apparatus 2010 has finished its cycle, or the cycle has been safely aborted.
Once the papers 2012 have been punched by all of the punches 2024, the motor 2080 rotates the rotatable post 2078 such that the paper clamp 2020, with the punched papers 2012 therein, is raised along the first axis 2038. The binding element insertion device 2022 is powered along the second axis 2102 by the motor 2108 toward the first axis 2038, as shown in
Once the paper clamp 2020 and the binding element insertion device 2022 are in their proper positions, based on the size of the binding element 2014, the motor 2116 reverses so that the finger pullers 2110 may return to their original position, thereby releasing the fingers 2098 of the binding element 2014. Because the fingers 2098 of the binding element 2014 are aligned with the holes in the papers 2012, the fingers 2098 pass through the holes, back toward the spine 2100, thereby binding the papers 2012.
As shown in
The controller 2170 may also be programmed to count the number of cycles that have been completed so that it may provide a signal to the user interface 2160 that indicates that the tray 2036 should be emptied. Because information about the thickness of the papers 2012 that are punched and bound in the apparatus 2010 is provided to the controller 2170, the count may be weighted to provide a more accurate signal.
A lid 2204 is operatively connected to the housing 2202 so that the lid 2204 may be moved between a closed position 2206, as shown in
As shown in the Figures, the user interface 2220 is provided on the housing 2202 in a location that is convenient to the user. As shown, the user interface 2220 is generally located on the top of the apparatus 2200. It is also contemplated that the user interface 2220, or even parts of the user interface 2220, described in further detail below, may be located on the front or the side of the apparatus 2200. The user interface 2220 is in communication with the controller 2221. The controller 2221, like the controller 2170 discussed above, is in communication with the various sensors and motors throughout the apparatus 2200. The controller 2221 may be a microprocessor with suitable software for controlling the operations of the apparatus 2200.
As shown in
For example, after the apparatus 2200 has been turned on, the screen 2228 may show an animation representative of the lid 2204 being opened, thereby communicating to the user that the lid 2204 should be moved from the closed position 2206 to the open position 2208. After the user has opened the lid 2204, a lid sensor (not shown) that has sensed the movement, or has sensed that the lid 2204 is now in the open position 2208, will provide a signal to the controller 2221, which signals the screen 2228 to generate an image that informs the user to insert the papers 2012 into the paper opening 2210, as shown in
After the paper 2012 has been loaded, and the presence of the paper 2012 has been detected, the controller 2221 may signal the screen 2228 so that the screen 2228 indicates that the user needs to press one of the input devices 2224 to proceed, as shown in
As seen in
Also shown in
Once the sensor 2130 senses that the correct binding element 2014 has been loaded properly, the screen 2228 may display the next action to be taken by the user. As shown in
The screen 2228 may then be programmed to provide an animation of the punching and binding operations as they are taking place. As shown in
Once the binding operation has been completed, the screen 2228 may indicate to the user that the paper 2012 has been successfully bound with the binding element 2014 and, as shown in
As shown in
In the embodiment of the apparatus 2200 shown in
Pre-punched covers 2260 to be bound with the papers 2012 may also be provided. As shown in
Another embodiment of a pre-punched cover 2260 is a wrap-around cover 2266, shown in
A method for binding a plurality of papers is generally shown in
At 2306, the visual display 2222 instructs the user to load the paper 2012 into the paper opening 2210, and the user then loads the paper 2012 into the paper opening 2210. The paper sensor senses that the paper 2012 has been loaded into the paper clamp 2020. The controller 2221 then instructs the visual display 2222 to instruct the user to engage the first input device 2230. In addition, the first input device 2230 may optionally provide an indication to the user that the user should engage the first input device 2230, such as by flashing a green light. The user engages the first input device 2230 at 2308 so that the thickness of the papers 2012 may be measured. The controller 2221 then signals the paper clamp 2020 to close. The sensor 2061 senses the thickness of the papers 2012 and communicates the thickness to the controller 2221, which determines which predetermined size, e.g. S, M. L, or XL, of binding element 2014 should be used to bind the loaded papers 2012 together. At 2310, the visual display 2222 instructs the user which size binding element 2014 to insert into the apparatus 2200 through the binding element opening 2212. The user inserts the binding element 2014 into the binding element opening 2212 at 2312. The sensor 2130 senses the size of the binding element 2014 that has been inserted and communicates the size information to the controller 2221. The controller 2221 determines whether the correct size of binding element 2014 has been inserted at 2314. If the incorrect size has been inserted, the visual display 2222 displays an error message, and the indicator portion 2226 indicates that an error has occurred in the binding element opening 2212 at 2316. The user removes the incorrect binding element 2014, and the method 2300 returns to 2312. If the correct size binding element 2014 has been inserted, the method 2300 proceeds to 2318, where the visual display 2222 instructs the user to move the lid 2204 to the closed position 2206. As instructed, the user moves the lid 2204 to the closed position 2206. Once the lid sensor senses that the lid 2204 is in the closed position 2206, the visual display 2222 instructs the user to engage the first input device 2230 to proceed with the punching and binding operation at 2320. After the user has instructed the apparatus 2200 to proceed by engaging the first input device 2230, the interlock device 2214 locks the lid 2204 in the closed position 2206 at 2322, and the punching and binding operation commences at 2324. During the punching and binding operation, the visual display 2222 provides status information to the user at 2326, such as the time remaining before the binding operation will be complete. Upon completion of the punching and binding operation, the interlock device 2214 unlocks the lid 2204 at 2328, the visual display 2222 instructs the user to open the lid 2204, and the user opens the lid 2204. Once the lid sensor senses that the lid 2204 is in the open position 2208, the visual display 2222 instructs the user to remove the bound document from the apparatus 2200 at 2330. After the user removes the bound document from the apparatus 2200, the method ends at 2332. Of course the method 2300 disclosed above may include additional steps or may not include one of the steps described. The illustrated method is not intended to be limiting in any way and is intended to describe but one possible method to bind the papers 2012 together using the apparatus 2200 described herein.
