The invention relates to a technique for marking a prolate object, for example a conductor. In particular, the invention relates to a device for providing a marking that is arranged or arrangeable in a closed manner around a prolate object.
For marking electrical conductors as an example, label printers are conventionally used for printing a label, which then has to be manually mounted on the conductor after the printing. The document U.S. 2003/146943 A1 describes a printer that alternately prints and cuts such a label.
Furthermore, special printers are known which may be used for conductor labeling. The document U.S. 2004/0211522 A1 describes a machine for winding around a conductor a pre-printed wrap-around label from a spindle roll. The document U.S. 2008/0073023 A1 describes a monolithic machine for printing and applying wrap-around labels.
However, conventional devices are capable of printing only certain labels and, if an automated application of the label is integrated into the device, no other printing applications are possible with such a device.
The document WO 1999/56271 A1 describes the opening of a printed shrink tube in order to push it onto a conductor. However, in the conventional technique for opening, it is well possible that the tube does not open when pressed by means of jaws on the longitudinal edges of the flattened tube, rather an upper and a lower half of the tube buckle in the same direction.
In an embodiment, the present invention provides a device for providing a tube arranged or arrangeable in a circumferentially closed manner around a prolate object, as a marking of the object, the device comprising: a printer configured to output a printed tube in a longitudinal direction or a material interface configured to receive a printed tube output from a printer in the longitudinal direction; a cutting unit configured to cut through the printed tube at a cutting position of the tube in a transverse direction transverse to the longitudinal direction of the tube, at least at the cutting position an upper half of the tube and a lower half of the tube, at an end and/or on an inside, abut each other or are connected to each other; and an opening unit configured to open upper and lower halves of the tube, the opening unit comprising at least two opening rollers each rotatable about a rotational axis, a respective rotational axis being perpendicular or substantially perpendicular to the longitudinal direction and to the transverse direction, wherein the at least two opening rollers abut against the cut and printed tube on opposite sides in the transverse direction or each is configured to drive a belt abutting against the cut and printed tube on opposite sides in the transverse direction.
The present invention will be described in even greater detail below based on the exemplary figures. The invention is not limited to the exemplary embodiments. Other features and advantages of various embodiments of the present invention will become apparent by reading the following detailed description with reference to the attached drawings which illustrate the following:
In an embodiment, the present invention provides a device for a printing system, preferably with the size and portability of a desk-top device, so that the system may be quickly converted to various applications of object marking, preferably various applications of conductor marking, including marking with a printed tube (or sleeve). Additionally, the printed tube may be reliably opened.
An aspect relates to a device for providing a tube (or sleeve) arranged or arrangeable in a closed circumferential manner around a prolate object, preferably a conductor, as a marking of the object. The device comprises a printer configured to output a printed tube (or sleeve) in a longitudinal direction, or a material interface configured to receive a printed tube output from a printer in a longitudinal direction. Alternatively or additionally, the device comprises a cutting unit configured to cut through the printed tube at a cutting position of the tube in a transverse direction that is transverse, preferably perpendicular, to the longitudinal direction of the tube, wherein at least at the cutting position an upper half of the tube and a lower half of the tube abut on each other or are connected to each other at the end (or terminally) and/or on the inside (or insidely). Alternatively or additionally, the device comprises an opening unit for opening the upper and lower halves of the tube, which comprises at least two opening rollers rotatable about a rotational axis in each case, the respective rotational axis being perpendicular or substantially perpendicular to the longitudinal direction and to the transverse direction, and the at least two opening rollers abutting against the cut and printed tube on sides opposite (or opposing) in the transverse direction or driving in each case a belt abutting against the cut and printed tube on sides opposite (or opposing) in the transverse direction.
The opening unit may be configured to separate the upper half of the tube and the lower half of the tube from each other and/or to open the cut and printed tube, for example terminally at the cut or continuously along the longitudinal direction. For example, the opening rollers may be used to detach the upper half of the tube from the lower half.
The opening rollers may open the printed tube, for example in a flattened state of the tube (i.e., pressed flat or kept flat), by flexing the tube. The tube may be opened starting from a flat state by applying the opening rollers at isolated locations (i.e., in a punctiform manner) to the longitudinal edge of the tube or in a linear manner (for example, by means of a belt running over the opening rollers).
The opening rollers may be arranged (or positioned) in pairs against the cut and printed tube at locations (or points) perpendicular to the longitudinal direction.
The device may further comprise an object centering unit configured to arrange the prolate object, preferably the conductor, in alignment or coaxially with the cut and printed tube.
The opening rollers may be configured to push the cut and printed tube along the longitudinal direction over or onto the prolate object for the arrangement circumferentially closed around the prolate object.
The device may further comprise a printing signal interface configured to capture (or detect or receive) a control signal as to the output of the printed tube. Alternatively or additionally, the device may comprise at least one sensor configured to capture (or detect or receive) a control signal for the providing of the marking.
The device may further comprise a roller drive configured to synchronously rotate the opening rollers about the respective rotational axis (and, if necessary, to drive the belts with it). The opening rollers, which abut against the cut and printed tube on opposite sides in the transverse direction, may rotate in opposite directions.
The roller drive may be configured to arrange the marking on the object in a circumferentially closed manner or to provide it for circumferentially closed arrangement, depending on the control signal for the outputting of the printed tube and/or the control signal for the providing of the marking.
The device may further comprise two carriages longitudinally movable in the transverse direction, on each of which at least one of the at least two opening rollers is rotatably mounted about the respective rotational axis. A distance between the two opening rollers of the respective pair of rollers and/or a pressure force of the opening rollers on the cut and printed tube may depend on a detected or measured width of the tube.
The device may further comprise a width sensor arranged between the holding-flat unit and the opening unit or between pairs of rollers of the opening unit, which is configured to measure the width of the tube (preferably before opening and/or during opening). Alternatively or additionally, the width of the tube may be acquired (or detected) via the data interface.
The circumferentially closed surface of the cut and printed tube as the marking may be simply-connected. For example, the circumferentially closed arrangement may comprise openings in the surface.
The device may be a device for providing a printed tube or for applying a printed tube to the prolate object (in short: applicator). Alternatively or additionally, the device may be a device for circumferentially arranging a printed marking around a prolate object, preferably around a conductor.

A printing medium of the printer may be a tube. A length of the tube as a printing medium may be any length or several times longer than the provided printed tube as a marking. The printing medium may be referred to as an endless tube. The printed tube that is output from the printer may also be referred to as a printed product. The printed product from the printer may comprise the printed tube. The (printed) marking may comprise the cut and opened printed tube.
The printer may receive an identifier via an interface (e.g., a network interface or a serial interface). The printer may be configured to print the received identifier onto a print medium using a printing material. The printing material may comprise a color ribbon, such as for thermal transfer printing. The printing medium (i.e., a printing substrate or label material) may be a plastic film, for example for heat sealing or welding, or a heat shrink tube. The printed product may comprise the printed medium printed by means of the printing material.
The providing may comprise arranging the marking on the prolate object, preferably arranging the marking circumferentially about a longitudinal axis of the prolate object. The at least one actuator may be configured to circumferentially arrange the printed marking about a longitudinal axis of the object.
For example, the opening unit may arrange or provide the marking when the control signal of the printing signal interface indicates the output of the printed product at the material interface and the control signal of the sensor indicates the presence of the object or a user request to provide the marking.
The device and the printer may be arranged side by side, for example without a direct mechanical connection. For example, the printer and device may each be arranged in a stationary and/or slip-proof manner on the same work surface. For example, a material interface of the printer may be aligned with, or may overlap with, the material interface of the device. There may be a clear gap between the printer and the device during operation.
The cutting unit may comprise a movable blade (preferably a longitudinally movable blade) which, for example, stands vertically and moves up in a controlled manner for cutting. The movable blade may slide over a stationary counter blade (or briefly: stationary blade). A through opening of the material interface may be arranged or formed between the blades, i.e. the printed tube may be transferred to the device between the blades.
A drive for the blade may be arranged below the material interface and/or may comprise an electric motor, a gearbox and a rack (e.g., for rack and pinion) mounted on the movable blade as a linear drive.
A cutting edge of the movable blade may be oblique (or non-perpendicular) to the direction of motion or may be V-shaped. A cutting edge of the stationary blade may be perpendicular to the direction of motion or V-shaped. The movable blade having an oblique cutting edge may comprise a guide pin that engages the stationary blade in an open position of the movable blade.

Alternatively or additionally, the heating elements may be arranged on both sides of the tube in the transverse direction. For example, the opening unit or an additional unit between the holding-flat unit and the opening unit comprises two heating elements that press on the tube and/or conduct heat on opposite sides of the tube in the transverse direction.
The printed tube may be guided by the holding-flat unit, in particular between two horizontal surfaces, a horizontal surface and a roller with a horizontal running surface, or two rollers with horizontal running surfaces.

The opening unit may abut directly against opposite edges (i.e. longitudinal edges) of the flat (i.e. still closed) tube or may drive at least two belts abutting against opposite edges on the tube. The opening rollers may apply (directly or via the belt) a horizontal compressive force to the respective edge of the tube. The opening rollers may be biased in the direction of the tube. Opening rollers may have a vertical rotational axis.
The opening rollers or the belts may be waisted. The opening rollers (and, if necessary, the belts with them) may be driven in the direction of movement of the tube.
Preferably, a plurality of opening rollers are arranged in pairs opposite each other on each side of the tube. The plurality of opening rollers may be driven synchronously.
The opening rollers (and, where appropriate, belts) may be mounted on carriages movable transversely to the longitudinal direction of the tube. A distance between the rollers or belts may be controlled by means of the movable carriages, for example as a function of the width or diameter of the tube. The width sensor may detect the width or diameter of the tube without contact, preferably optically.
The device may further comprise a reduced pressure opening unit (or vacuum opening unit) comprising at least one suction cup, preferably at least two suction cups. The suction cup or cups may each be brought into contact with the upper half of the tube and/or the lower half of the tube. By means of a reduced pressure in the respective suction cup, the vacuum opening unit is capable of at least partially separating (or releasing or detaching) the upper half of the tube and the lower half of the tube from one another when the tube is opened.
Opening the tube may open the tube non-destructively. The upper half of the tube and the lower half of the tube may be connected at the longitudinal edge of the tube and remain connected.
The vacuum opening unit may be part of the opening unit, may be part of the holding-flat unit, or may be arranged between the holding-flat unit and the opening unit.

The device 100 may be configured to apply the marking 101 to the conductor 102 when the conductor 102 is already mounted (for example, when a distal end of the conductor is contacted or both ends of the conductor are contacted and/or one or both ends of the conductor are not free ends). Preferably, the conductor 102 will not be rotated about a transverse axis transverse to the longitudinal direction 210 of the conductor 102 and/or will not be rotated about a longitudinal axis parallel to the longitudinal axis of the conductor 102 and/or will be at rest during application.
The tube 101 applied to the conductor 102 may be captive. Alternatively or additionally, a printed surface of the applied tube 101 may be planar or substantially free of curvature. For example, the printed surface may be arranged between two embossments in the tube 101 that are parallel to the longitudinal direction. As a result, the printed surface may be easily readable and/or sufficiently large.
The marking 101 may be durable, for example, in terms of printing (preferably in that the printer 200 is a thermal transfer printer), in terms of the material of the printing medium 208 (for example, in that the tube comprises a thermoplastic as the printing medium 208), and/or in terms of attachment to the conductor 102 (for example, in that the marking 101 is positively, frictionally, and/or adhesively connected to the conductor 102).
The tube 101 as marking may be space-saving, for example so that a plurality of conductors 102, each carrying such marking 101, may be arranged in close proximity to one another. Alternatively or additionally, the marking 101 may be displaceable and/or rotatable, for example by positively connecting the marking 101 to the conductor 102. This may allow the marking 101 to be aligned on conductors 102 (such as cables) that are in close proximity to each other.
The first embodiment example of the device 100 shown in
The embodiment of the printer 200 comprises a print head 202, a print roller 204, a light barrier 212 for detecting the printing medium 208 (i.e., the material to be printed), for example, for detecting control holes, (for example, black) control marks, a beginning and/or an end of the printing medium 208. The printing material 206 is, for example, a color ribbon.
The material 208 to be printed is guided between the print head 202 and the print roller 204, along with the color ribbon 206. The light barrier 212 may detect a beginning of the printing medium 208 during printing to ensure positioning of the printed image within the portion of the printed product 214 by means of which the marking 101 is formed.
The printer 200 comprises interfaces that are spatially associated with and/or functionally correspond to the interfaces of the device 100, respectively. The spatially assigned and/or functionally corresponding interfaces are connected or connectable to each other in pairs.
Preferably, the printer 200 comprises a mechanical interface 252 that is connected or connectable to or that is in communication with or can be brought in communication with the mechanical interface 152 of the device 100. Preferably, the spatial association implies that when the mechanical interface 152 and 252 are connected (e.g., interlocked), the other interfaces of the device 100 and the printer 200 are also respectively connected or interchangeable.
Alternatively or additionally, the printer 200 comprises a data interface 258, which is connected or connectable to the data interface 158 of the device 100 or which is, or can be brought, in communication (or exchange) with the data interface 158 of the device 100. Alternatively or additionally, the printer 200 comprises a material interface 256, which is connected or connectable to the material interface 156 of the device 100 or which is, or can be brought, in communication (or exchange) with the material interface 156 of the device 100.
For example, the material interfaces 156 and 256 are in connection or are interchangeable for exchanging the printed product 214. The data interfaces 158 and 258 are in connection for exchanging measurement data from the respective sensors 104, 106 and/or 212 and/or control commands from the control unit 130 of the device and/or from a control unit 230 of the printer 200.
Optionally, as shown by way of example in
The device 100 for providing the tube 101 as a marking, preferably for circumferentially arranging the tube 101 around the conductor 102 (i.e., applying the marking 101 to the conductor 102), is also referred to as an applicator.
An embodiment of the device 100 (for example, the aforementioned first embodiment of the device 100) or a printing system comprising an embodiment of the device 100 and an embodiment of the printer 200 (for example, the aforementioned embodiment of the printer 200) are configured to perform one or more of the following functions and method steps.
The device 100 and the printer 200 may perform operations (also referred to as actions), i.e., a set of one or plurality of process steps, alternately, particularly in providing the tube 101 or arranging the tube 101 (i.e., applying the marking 101 to the conductor 102). In doing so, the device 100 (or its control system 130) and the printer 200 (or its control system 230) communicate with each other via the data interfaces 158 and 258, respectively, for example to exchange or coordinate parameters (also: operation parameters), start, completion and/or timing of the operations (preferably of the next operation in each case). Alternately performing the operations may comprise interleaved operation of the device 100 and the printer 200.
In a first implementation, an overall sequence control is stored (e.g., implemented or executably stored) in the printer 200, for example, in the control unit 230 (preferably by means of firmware stored in the control unit 230). The overall sequence control may comprise printing on the printing medium 208 and applying the printed product 214 resulting from the printing.
A sequence control of the device 100 may be stored (e.g., implemented or executably stored) in the device 100 and/or the printer 200. The sequence control of the device 100 may comprise (preferably exclusively) providing or applying the marking 101 to the conductor 102 by means of the printed product 214. For example, the marking 101 is provided or arranged or applied to the conductor 102 by executing the sequence control of the device 100.
In other words, the execution of the sequence control of the device 100 may be executed partially or entirely in the device 100 or exclusively in the printer 200. In any case, execution of the sequence control of the device 100 causes the marking 101 to be provided or applied to the conductor by means of the device 100.
In a first variant of the first implementation, the sequence control of the device 100 is stored in the printer 200. The device 100 preferably does not have any sequence control, for example, it also does not have a control unit 130. The control unit 230 of the printer (for example, the firmware of the printer 200 in the control unit 230) is configured to (preferably individually) control (or drive) or (preferably individually) query (or detect) the actuators (for example, 120 and/or 122) and sensors (for example, 104 and/or 106) of the applicator 100 via the data interfaces 158 and 258.
In a second variation of the first implementation, the sequence control of the device 100 is stored (e.g., implemented or executably stored) in the device 100. For example, the device 100 comprises the control unit 130 or the regulating unit 130 in which the sequence control of the device 100 is stored (e.g., implemented or executably stored). Preferably, the control unit 130 or the regulating unit 130 is configured to control or regulate the providing or applying. For simplicity and without limitation, reference is made herein to the control unit 130, i.e., the function of a closed-loop control is optionally comprised.
Execution of the sequence control (preferably in the control unit 130) is started by the printer 200 (for example, the control unit 230, preferably by means of the printer firmware). For this purpose, the device 100 may receive a control command via the data interface 158 or may be energized via the electrical interface 154. As soon as an operation of the device 100 is required, the printer 200 (for example, the control unit 230, preferably by means of the printer firmware) outputs a signal as a control command to the device 100 via the data interface 258 or 158.
Preferably, the printer 200 waits while the device 100 performs the requested operation (for example, initiated by the control command). Once the device 100 sends (e.g., reports) a signal via the data interface 158 or 258 as a control command of completion of the operation, the printer 200 continues execution of the overall sequence control.
Optionally, the signal from the applicator 100 to the printer 200 indicates a status of completion of the operation. For example, the status may indicate successful completion or an error that occurred during execution of the operation.
In a second implementation, the device 100, for example the control unit 130 (preferably by means of firmware of the applicator 100) executes the overall sequence. In other words, the overall sequence control is stored (e.g., implemented or executably stored) in the device 100, for example, in the control unit 130 (preferably by means of firmware stored in the control unit 130). By executing the overall sequence control, the device 100 controls the overall sequence.
The printer 200 acts as a slave in the overall operation. For example, the printer 200 has sovereignty over the printed image, i.e., the printer 200 (preferably its control unit 230) performs the printing as an operation of the printer 200 in response to a corresponding control command from the device 100. Optionally, the printer 200 issues a control command (i.e., a first start command) to execute the overall sequence control, for example, because only the printer 200 knows about the content and/or the presence of a print job.
To implement the interleaved operation, the device 100 and the printer 200 exchange information (for example, measurement data and/or control commands) using the data interface 158 and 258, respectively.
The exchanged information may comprise measured values (for example, electrical voltages, electrical currents, electrical frequencies), preferably measured values of the sensor 104 and/or 106, which are transferred (i.e., sent) from the device 100 to the printer 200. Alternatively or additionally, measured values of a sensor of the printer 200 (for example, the light barrier 212) may be transferred (i.e., sent) from the printer 200 to the device 100. The device 100 or the printer 200 may determine (for example, calculate) sequence control parameters based on the measured values and/or transmit the measured values or the parameters to the computer or computer network 300 (for example, to application software) via the interface 222.
For example, the sensor 106 may detect a diameter or circumference of the conductor 102 (or the prolate object about its longitudinal axis). The control unit 130 and/or the control unit 230 may determine a length of a feed of the printing medium 208 and/or a selection of the printing medium 208, for example, depending on the detected diameter or circumference.
Furthermore, when a defined threshold value is exceeded, these measured values may be transferred as a digital signal (for example, either as a state “0” or a state “1”) to the data interface 158 or 258, respectively, in order to inform the other (printer 200 or device 100, respectively) when a defined state (for example, the completion of an operation). For example, reaching an end position or a reference point of an actuator (for example, actuator 120 and/or 122) may be indicated.
A reference move of an actuator of the applicator 100 (for example, the actuator 120 and/or 122) may serve to mechanically move the actuator (i.e., a drive connected to a mechanism of the applicator 100) to a determined position of the actuator (i.e., the mechanism), referred to as a reference position. A control command from the printer 200 or a process step of the operation, sequence control, and/or overall sequence control performed by the applicator 100 may comprise a motion (for example, a travel command) of the actuator, with the reference position serving as a reference point for the motions.
When the control unit 130 of the device 100 (for example, its applicator firmware) calculates one or more parameters of the provisioning or application (i.e., sequence control) from measured values (for example, transferred from the printer 200 or detected by the sensor 104 and/or 106), this or these may be transferred to the control unit 230 of the printer 200 (preferably to its printer firmware) in accordance with a communication protocol via the data interface 158 and 258. Furthermore, the control unit 130 of the device 100 (preferably its applicator firmware) may also use measurement data detected by the printer 200 (for example, measurement data of the light barrier 212) to control the sequence control of the device 100 (for example, as parameters of the provision or application).
The printer 200 may be configured to print normal labels, for example, when no device 100 is attached to the mechanical interface 152 and/or the data interface 158.
The printer 200 may be a thermal transfer printer. The thermal transfer printer may provide high contrast and consistent marking 101. For example, the printer 200 may be a thermal transfer roll printer.
The embodiment of the printer 200 comprises an unroller 216 (or source roller) of the printing medium 208 disposed upstream of the print head 202, an unroller 218 (or source roller) of the printing material 206 disposed upstream of the print head 202, and a rewinder 220 (or target roller) of the printing material 206 disposed downstream of the print head 202.
An electrical interface 254 of the printer 200 is configured to provide electrical power to the device 100 attached to the printer 200 via the electrical interface 154 thereof.
The second embodiment of the device 100 may be implemented independently or as a further embodiment of the first embodiment of the device 100. Features of the first and second embodiments of the device 100, which are denoted by the same reference numerals, may be identical or interchangeable.
The second embodiment of the device 100 is configured to provide a tube (for example, a heat-shrinkable tube) as a printing medium 208 and/or a printed tube as a printed product 214 and/or an opened tube 101 as a marking and/or to push or attach it to the conductor 102. When the tube is printed and/or cut (for example, by means of the first actuator 120 of the device 100), the tube is pressed flat, whereby its cut end or at least a portion of the printed tube may be closed, i.e., the cut edge or the inner sides of the tube 214 (i.e., the upper and lower halves of the tube 214) adhere to each other.
The second actuator as opening unit 122 is configured to open the adhering cut edge of the printed tube and/or the adhering inner sides (i.e. the halves of the tube) of the printed tube 214. To this end, the opening unit 122 comprises (preferably waisted) rollers 123 that exert a force in pairs on opposite lateral edges of the printed tube 214 to open the cut edge of the tube and/or to release the inner sides of the tube from each other. In the schematic illustration of
In the second state shown in
The rollers 123 are rotatable about rotational axes 123A perpendicular (for example vertical) to the longitudinal direction 210 and to the transverse direction 121, preferably driven to feed the printed tube 214.
The device 100 comprises a print head 202, or a material interface 156 for receiving a tube as a printed product 214 from a print head, a cutting unit 120, and an opening unit 122. The opening unit 122 may comprise a roller alley having rollers 123.
Optionally, a roller arrangement 240 (preferably an arrangement of roller pairs) is incorporated into the transport process. The roller arrangement 240 comprises at least two pairs of rollers, for example 2 or 3 pairs of rollers. A first pair of rollers 242 is arranged in the transverse direction 121 (for example, horizontally). A further (or in the longitudinal direction 210 farther) pair of rollers 242 is arranged perpendicular to the longitudinal direction 210 and perpendicular to the transverse direction 121 (for example vertically).
The roller arrangement 240 may be arranged in front of the flat holding device 160. An optional third pair of rollers 246 (counted in the longitudinal direction 210) of the roller arrangement 240 may be arranged in the transverse direction 121 (for example, horizontally).
The rotational axes of a pair of rollers are parallel to each other. The rollers of a pair of rollers are arranged to convey the printed tube 214, for example, appropriately spaced and/or force-loaded perpendicular to the respective rotational axis.
Optionally, the horizontal pair of rollers may form the compartment retaining unit 160. At least the pair of rollers with a vertical rotational axis may have rollers with a circumferential groove.
Preferably, the opening unit 122 or the holding-flat unit 160 is configured to expand the tube 124 by heating one side. For example, the holding-flat unit 160 comprises a heating element 162 (preferably a heating wire). The heating element 162 may be arranged in a stationary and/or longitudinally movable holding-down edge (for example, the holding-down edges 700 and/or 710 described below) in the holding-flat unit 160 or spaced therefrom. As a result of heating on one side, the tube 214 (for example, a heat shrink tube) contracts on one side and inevitably bulges out.
Optionally, air may be blown against the longitudinal direction onto or into a cut end of the tube 214 for opening the upper and lower halves of the tube. Alternatively or additionally, the opening unit 122 may comprise a needle wheel or wheels that penetrate the tube 214 to open and/or expand the tube 214 upon feed.
A detection of the tube 214 may be done optically, inductively or capacitively by means of the inserted conductor 101.
The opening rollers 123 are preferably movable in the transverse direction 121, for example the opening rollers 123 exert a predetermined and/or controlled force on the longitudinal edge of the printed tube 214.
Providing the opened, cut, and printed tube 101 (for example, including printing using the printer 200) may be controlled or initiated by a sensor 106. The sensor 106 may detect the presence of the conductor 102 (for example, in a non-contact manner). Alternatively or additionally, the sensor 106 may comprise a push button (also: operator button) that is actuated by a user as a control signal for provisioning (i.e., provisioning request). The control button may be positioned to be actuated by the hand holding the conductor 102.
The opening process may be assisted by pulling on the outer surfaces, i.e., the upper and lower halves of the tube. Optionally, the opening unit 122 or a vacuum opening unit 170 comprises two or at least two suction cups that are pressed onto the surface of the tube (for example, onto the upper and lower halves of the tube, respectively).
Alternatively or additionally, air may be injected against the conveying direction 210, i.e., terminally at the intersection (or cutting position) of the tube. In this case, the longitudinal edges (i.e., the outer edges) of the tube are fixed in the opening rollers 123 (for example, the pairs of rollers of the opening unit 122) and the tube must not protrude, or not protrude too far, from the opening unit 122 (i.e., the last of the pairs of rollers in the conveying direction 210).
The opening unit 122 comprises opening rollers 123, which generate a flexing work by a bias in the transverse direction 121 towards the tube 214 and thereby open or pre-open the tube 214, which has been flattened (preferably by means of the holding-flat unit 160). The opening or pre-opening may be performed by a movement profile of the opening rollers 123. The movement profile may be part of the provisioning process. In this case, the opening rollers 123 are motor-driven to rotate (rotate) about rotational axes 123A. A synchronous rotation of the rollers 123 is implemented via gears or a belt drive.
The opening rollers 123 are preferably profiled, e.g. V-shaped or waisted.
Preferably, the tube 214 (for example, a heat shrink tube) is thus opened only from the outside.
The opening rollers 123 press the tube 214 open punctually from the outside. Alternatively or additionally, the tube 214 may be opened by line contact from the outside. The latter can be realized, for example, by belts around the opening rollers 123. The belts may be flat belts or (for example, like the opening rollers 123) may be profiled.
The opening unit 122 comprises carriages 124 movable in the transverse direction 121. For example, the carriages 124 are movable by means of a linear gear 126 driven by a drive 128 of the carriages 124. A transverse guide 127 of the carriages 124 may comprise sliding bearings.
The carriages 124 may assume at least one of the following positions or postures, for example controlled by the control unit 130 and/or 230: In a conveying position, the tube 214 may be moved forward and/or backward in the longitudinal direction 210 by rotating the rollers 123. In a flexing position, flexing of the tube 214 may be performed to open it. The fulling position and the conveying position of the carriages may coincide. In a release position, the carriages may move apart, for example to remove the opened tube 101.
The opening rollers 123 are positioned on movable carriages 124, which allow the tube 214 to be opened further. The carriages 124 may be motor-driven. The opening rollers 123 are positioned on movable carriages which enable them to adapt automatically to different tube sizes (width adjustment), for example depending on a width of the tube 214 measured by a width sensor.
The control system 130 and/or 230 may be configured to move the opening rollers 123 according to a motion profile. The motion profile is a combination of an advancing motion in the longitudinal direction 210 by rotation of the opening rollers 123 and a motion of the carriages 124 on which the opening rollers 123 are rotatably mounted. The one or more movement profiles may allow the tube 214 to be opened, pushed onto the conductor 102 (for example, provided arrangeable on the conductor 102), and/or removed from the applicator (for example, provided arrangeable).
The motion profile may be adjusted by (preferably using sensors 104, 106, and/or 212) measured (i.e., dynamically detected) material quantities, such as a width of the tube 214, during execution of the motion profile (i.e., dynamically).
The tube width may be obtained from print data (for example, from the printer 200 or the computer or computer network 300) and/or detected by a width sensor (for example, one of the sensors 104, 106, and/or 212). The width sensor may comprise a line sensor (for example, using a charge-coupled device or CCD) or a camera (for example, using a complementary metal-oxide semiconductor or CMOS).
The width sensor (for example, the line sensor) is arranged directly at the material interface 156 or 256 (i.e., the outlet of the printer 200) or between the holding-flat unit 160 and the opening unit 122 (i.e., upstream of the first pair of opening rollers in the feeding direction 210). The width sensor may also be used to control the motion profile.
The sensor 106 may be configured to detect that an object 102 to be marked (for example, the conductor, preferably a cable) is (or will be) inserted into the device 100 or is (or will be) inserted into the provided opened tube 101.
By means of the sensor 106, the movement profile may be controlled. For example, arranging (for example, threading) the provided opened tube 101 (i.e., a piece of tube) on the conductor 102 and/or releasing the tube 101 arranged on the conductor 102 by moving the opening rollers 123 laterally away from each other (i.e., by moving the carriages 124 apart in the transverse direction 121).
The sensor 106 may be movable in the feeding direction 210, for example, to allow the conductor 102 to be inserted or deployed (for example, in an application-specific and/or user-controlled manner) into the device 100 to varying degrees in opposition to the longitudinal direction 210, before initiating or continuing the motion profile in response to detecting the conductor 102 (as a control signal for deployment).
The sensor 106 may comprise a sensor for detecting the conductor 102. The sensor may detect the conductor 102 inductively, capacitively, optically, and/or tactilely. Alternatively or additionally, the sensor may implement at least one of the following sensing capabilities.
For a first sensing option, the sensor 106 is arranged between two adjacent pairs of rollers of the opening unit 160 (i.e., opening rollers 123 that abut or can be brought into abutment with the tube 214 at locations opposite in the transverse direction 121). The sensor 106 (for example, a capacitive or inductive sensor) measures whether a conductor 102 has been inserted. By using a plurality of sensors 106, the user may determine how far the conductor 102 should be inserted before triggering (i.e., initiating) the deployment (for example, the motion profile).
For a second sensing option, the sensor 106 (for example, a capacitive or inductive sensor) measures perpendicular to longitudinal direction 210 (preferably also perpendicular to transverse direction 121, for example, in a vertical direction) whether the conductor 102 has been inserted into the device 100 as an object to be marked.
Optionally, the sensor 106 may be movable in the longitudinal direction 210, which may allow the user to determine how far the conductor 102 should be inserted before initiating provisioning (for example, before triggering the motion profile).
For a third sensing option, alternatively or additionally, the width sensor (which is configured to measure the width of the tubing) may further detect the presence of the conductor 102. For example, the width sensor may detect the conductor 102 if the conductor 102 is to be fully inserted into the tube 101.
In one variation of each of the above sensor options, the sensor 106 comprises a light barrier (for detecting the conductor 102 in transmitted or reflected light, for example).
Optionally, the user (i.e., the operator of the device 100) may influence the provisioning (preferably the motion profile) through data input. The data input (for example, at a user interface of the device 100, a user interface of the printer 200, a user interface of the printing system, and/or via the computer or computer network 300) may comprise parameters of the provisioning (preferably the motion profile). The parameters may comprise an opening width (for example, of the opened tube 101) and/or an output position (for example, in the longitudinal direction 210) of the provided tube 101. For example, the parameters may be changed and/or stored in operation.
The parameters (also referred to as operation parameters) may be application-specific or article-specific. The operation parameters may be stored in the device 100, the printer 200, or the controlling software of the computer 300. The parameters may control provisioning (for example, the motion profile). The parameters may control or affect advancing or retracting the tube and/or flexing the tube. Alternatively or additionally, the parameters may determine whether to perform clamping or holding the tube flat and/or pre-opening.
In any embodiment, insertion of the conductor 102 may be aided by visual aids, such as reflective surfaces, a magnifying glass, and/or a camera (the image of which may be transmitted to the printer via the data interface 158 or 258, for example, and/or displayed on a display 209 of the printer 200). By means of reflective surfaces, a rear of the conductor 102 may be visible to the user.
In any embodiment, an object centering unit 180 (also: centering aid) may be provided for inserting or positioning the conductor 102. The object centering unit 180 may be arranged downstream of the opening unit 122 in the longitudinal direction 210.
Alternatively or additionally, a sleeve or collet may be pushed through the tube 101 to grip the conductor 102 and pull it through the tube 101.
Optionally, in each embodiment of the device 100, there may be installed a unit configured to shrink, for example heat, the tube 101 at the end of deployment.
The cutting unit 120 comprises a longitudinally movable blade 600 (also: knife), for example guided in at least two or four guides 602. The guides 602 may be arranged in pairs on longitudinal edges of the blade 600 opposite each other in the transverse direction 121.
The blade 600 is preferably longitudinally movable perpendicular to the longitudinal direction 210 and perpendicular to the transverse direction 121.
The longitudinally movable blade 600 comprises a cutting edge 604. The printed tube 214 is cut between the longitudinally movable blade 600 and a stationary blade 610 by shear forces. A cutting edge of the stationary blade 610 may be parallel to the transverse direction 121.
The cutting edge 604 of the longitudinally movable blade 600 may be parallel to the transverse direction 121 and/or parallel to the cutting edge of the stationary blade 610. In other words, the cutting edge 604 of the longitudinally movable blade 600 may be perpendicular to the cutting direction (i.e., the direction of movement of the longitudinally movable blade 600).
Alternatively, as shown schematically in
Preferably, the longitudinally movable blade 600 includes a guide pin 606 arranged to guide the longitudinally movable blade 600 past the stationary blade 610 without gaps and/or untilted or unwedged. In other words, the guide pin 606 is configured to prevent the longitudinally movable blade 600 from abutting the stationary blade 610 when the longitudinally movable blade 600 slides over the stationary blade 610 for cutting through the tube 214. Preferably, the guide pin 606 extends beyond the cutting edge 604 in the direction of movement of the longitudinally movable blade 600. In other words, the guide tang 606 is leading during cutting through.
A drive 608 of the longitudinally movable blade 600 is powered by the electrical interface 154 and/or controlled by the control system 130 and/or 230.
The holding-flat unit 160 is configured to selectively clamp the tube 214. The holding-flat unit 160 is preferably arranged close to the opening unit 160, for example arranged in the longitudinal direction 210 one or a few diameters of the tube 214 away from the opening unit 160. That is, when pressing on the longitudinal edges of the tube 214 by means of the opening rollers 123, the holding-flat unit 160 is not too far away so that the tube 214 (for example, on the input side of the opening unit 160) is kept flat or is pressed flat. The flat holding or flattening may be implemented by holding-down edges 700 and 710 each extending in the transverse direction 121, for example as shown schematically in
The holding-down edges may comprise a longitudinally movable holding-down edge 700 and a stationary holding-down edge 710. Preferably, the longitudinally movable hold-down edge 700 is longitudinally movable perpendicular to the longitudinal direction 210 (i.e., the feeding direction) of the tube 214 and perpendicular to the transverse direction 121.
Preferably, a longitudinally movable frame 702 comprises the longitudinally movable holding-down edge 700. Alternatively, or in combination, a stationary frame 712 comprises the stationary holding-down edge 710.
A resilient coupling 704 (for example, as shown in
Preferably, the drive 608 of the cutting unit 120 also drives the holding-flat unit. For example, the longitudinally movable blade 600 comprises a stop 616 arranged to move the longitudinally movable holding-down edge 700 (for example, the longitudinally movable frame 702) against the force of the resilient coupling 704 to a closed position in which the holding-down edges 700 and 710 hold the tube 214 flat. For example, after cutting through, the drive 608 may move the longitudinally movable blade 600 further out of a conveying plane of the tube 214 (i.e., move it away from the tube 214), with the stop 616 moving the longitudinally movable frame 702 to the closed position of the holding-flat unit 160.
When cutting through (which, with respect to providing a marking 101, precedes holding flat, for example), stop 616 and longitudinally movable frame 702 may be out of mesh.
Optionally, the arrangement 240 of the pair of rollers, or at least one of the horizontal pairs of rollers 242 and 246, may be part of the device 100 as the holding-flat unit 160. Alternatively or additionally, the arrangement 240 of the pair of rollers may be part of the printer 200, for example as shown in
Distances between the rollers of each of a plurality of pairs of rollers 244 may decrease in the longitudinal direction, as shown schematically based on the rollers 244' (V arrangement).
A control unit 230 of the printer 200 controls a feed and/or a retraction of the printing medium 208 at the print head 202 and/or of the print product 214 at the material interface 256 (and consequently at the material interface 156 of the device 100) depending on the signals of the light barrier 212 and/or control commands obtained from the device 100 via the data interface 258 (i.e., via the data interface 158 of the device 100). For this purpose, the control unit 230 may control a drive (for example, a stepper motor) for rotating the print roller 204.
The light barrier 212 may be arranged in front of the print head 202 and/or the print roller 204 with respect to a direction of movement 210 of the printing medium 208 during feed. The light barrier 212 may comprise, as exemplarily shown in
The print head 202 comprises a plurality of heating elements. When the heating elements are heated (for example, energized) and the print roller 204 applies a predetermined (for example, sufficiently large) pressure to the printing medium 208, the color pigments are transferred from the printing material 206 (for example, a color ribbon) to the medium to be printed. The control unit 230 may control the stepper motor to rotate the print roller 204 and control the energization of the heating elements of the print head 202.
The printing material 206 may comprise a plurality of layers. For example, the printing material 206 may comprise a carrier material 206A (for example, a carrier film) facing away from the printing medium 208 and a color layer 206B (for example, a color wax) facing toward the printing medium 208.
The printer 200 is preferably a tabletop device to which the device 100 may be attached as an interchangeable module, for example, specific to an application or for the duration of a unified application operation.
Each embodiment of the device 100 may be used by the following operating steps B1 to B17 and/or perform the following steps.
B1: The operator generates the print data on a PC 300 or a mobile device 300, for example a tablet computer or cell phone. Here, the printing material is already selected and the tube size and/or tube type are taken into account accordingly.
B2: The operator mounts the device 100 on the printer 200.
B3: The operator loads the print material into the printer 200, guides the printing medium 208 between the print head 202 and the ribbon 206, adjusts the material guide and optionally other adjustments, and closes the print head 202.
B4: The operator switches on the printer 200.
B5: The printer 200 (for example, the control system 230) recognizes the device 100 (for example, as an applicator) via the data interfaces 158 or 258, and initializes the printer 200 and the device 100.
B6: The operator sends a print job to the printer 200 via the print function of a computer 300 (for example, a personal computer) or a mobile device 300 (for example, a device 300 in data communication with the printer 200 via a wireless network or a cellular network).
B7: The printer 200 detects the beginning of the printing medium (or printing material) 208 via the light barrier 212 or alternatively performs a reference cut (for example, by means of the cutting unit 120 of the device 100 or another cutting unit of the printer 200). The reference cut may produce a piece of tubing of a manually removable length.
B8: The printer 200 prints a first section or piece of tubing 214.
B9: The printer 200 transports the piece of tube 214 (through the material interfaces 156 or 256) to the cutting position of the tube or to the cutting position of the cutting unit 120.
B10: The device 100 (for example, controlled by the control system 130) cuts the tube 214.
B11: The device 100 (for example controlled by the control system 130) takes over the cut and printed piece of tubing by means of the opening rollers 123.
B12: Meanwhile, the printer 200 pulls the printing medium 208 back (for example, while it is being supplied by the device 100) to the print start of the next piece of tubing.
B13: The device 100 travels a certain movement profile, for example depending on the material 208. The providing (for example, the motion profile) may comprise a lateral stroke, keeping the tube flat by means of the holding-flat unit 160, pushing the opening rollers by moving the carriages 124 in the transverse direction 121, flexing the tube by rotating the opening rollers 123, for example, with back and forth movement of the tube in the longitudinal direction 210, pre-opening the tube in the clamped or flat-held state, pre-opening by means of a suction cup, and/or pre-opening by means of the heating element 162.
B14: The device 100 provides the opened tube 101 for arranging (for example, threading) the tube 101 onto the object 102 (for example, a carrier, preferably a conductor, such as a cable).
B15. The user acknowledges (for example, using the push button as a sensor 106) that the object 102 is positioned (for example, inserted into the device 100), and/or the device 100 detects the presence of the object 102 using the sensor 106.
B16: The device 100 releases the arrangeable tube 101 or transports the tube 101 (i.e., piece of tubing) toward the inserted conductor 102, for example, for threading the conductor 102 in the tube 101.
B 17: The next print job may be started.
In the case of one or more print jobs (for the provision of a tube 101 or with a plurality of tubes 101), an interleaved sequence preferably occurs between device 100 and printer 200. In the case of a print job for a plurality of tubes 101, an interleaved sequence preferably occurs between device 100 and printer 200 so that the next tube 214, after the previous tube 101 has been cut and the printing medium 208 has been withdrawn, may be immediately printed and fed to device 100.
A method 1100 performed by the device 100, preferably by the control system 130, may comprise at least one of the following steps S1 to S24.
