The present invention relates to an apparatus, and method for supporting and severing an object of interest, and more specifically, to an apparatus which supports a rigid, yet flexible material that is to be severed, in a predetermined planar orientation, and thereafter controllably moves a cutting device, in a given manner, so as to sever a predetermined region of the object of interest while simultaneously maintaining the object of interest in the given predetermined planar orientation.
Various machines have been developed, and have been commercially deployed through the years, and which are useful for severing or otherwise cutting objects of interest which are often presented or provided in the form of a substantially continuous rolls. The material which is formed into the aforementioned roles to be selectively severed may include various metals, synthetic materials, and the like.
The prior art attempts to provide a means for severing a ridged, yet flexible and continuous object of interest have taken on various forms. For example, the Office's attention is directed to International Publication No. WO 2012/002801 A1, to the Applicant Therp Holding BV, and which relates to a work piece support for supporting a generally plate-like work piece for processing by a thermal cutting tool. In the aforementioned International publication, the Applicant discloses an invention for supporting a generally plate-like work piece which includes a plurality of rows of supporting elements which are movable between a supporting position, and where they support the work piece, and a non-supporting position where they do not support the work piece, and a processing unit is provided to control the movement of the supporting elements based upon the position of a thermal cutting tool which is employed with same. In this arrangement, the work piece supporting elements comprise, at least in part, an electromagnet arranged to perform the individual movement between either the supporting position, or the non-supporting position. The aforementioned reference goes into some detail regarding the problems associated with the prior art attempts to sever either flexible, or smaller sized objects of interest using cutting tools as described, above.
While theoretically, a device as described in the aforementioned International Publication should be able to support a flexible material in a manner such that accurate severing or cutting of same can be accomplished, it is well known that the use of electromagnets arranged in the manner, as described, to perform the individual movements has proven, overtime, to be less than ideal in maintaining flexible substrates, and other objects of interest, such as thin sheets of metal, in a predetermined, planar orientation so as to allow precise severing or cutting of the flexible material to take place. Further, the use of magnetically actuated supporting elements has repeatedly proven to be problematic when the object of interest to be severed is also a magnetically attractive material. In this regard the debris which is often generated by the cutting or severing process often becomes adhered to the adjustable and magnetically driven support member thereby causing them to individually malfunction, over time. Consequently, the adjustment of the magnetically driven support members has proven to be problematic based upon the composition of the object of interest which is being severed. As will be appreciated, a failure to maintain an object of interest to be severed, in a proper planar orientation, results in a severing or cutting of the object of interest which is often less than accurate because of the non-planar orientation of the object of interest being severed. Furthermore, the repeated exposure of magnetic support assemblies as described in the prior art to a high temperature environment such as might be occasioned by exposure of the magnetic support members to the thermal temperatures occasioned by the operation of a thermal cutting tool often has resulted in the inaccurate positioning of the magnetic support member relative to the object of interest being severed. This, again, has created inaccurate cuts being made in the objects of interest being severed. Finally, the use of magnetic support members has proven to be less than ideal because the fine adjustment of the length dimension of each of the magnetic support members has been often difficult to achieve especially if cutting debris adheres to the respective magnetic support members.
Therefore, a method and apparatus for supporting and severing an object of interest which avoids the problems and detriments associated with the prior art teachings utilized, heretofore, is the subject matter of the present invention.
A first aspect of the present invention relates to an apparatus for supporting and severing an object of interest which includes a frame for positioning an object of interest, which is to be severed, in a given, predetermined, planar orientation; a cutting device which is selectively, and moveably mounted in spaced relation relative to the frame, and which, when rendered operable, severs the object of interest which is positioned in the predetermined, planar orientation on the frame; a multiplicity of orientation units which are mounted on the frame, and which are further selectively, and mechanically adjustable, as to length, so as to individually position, and maintain the object of interest to be severed in the predetermined, planar orientation while being severed; and a controller, operably coupled with each of the cutting device, and multiplicity of orientation units, so as to effect an optimal severing of the object of interest while maintaining the object of interest in the predetermined planar orientation on the frame, and which further simultaneously, and selectively displaces the individual orientation units from a supporting position relative to a region of the object of interest where the cutting device is currently severing the object of interest.

Still further, a method for supporting and severing an object of interest includes the steps of, providing a source of an object of interest to be selectively severed; providing a frame which has top and bottom surfaces, and a peripheral sidewall, and which further defines an internal cavity, and supporting at least a portion of the source of object of interest to be severed in a given, predetermined planar orientation relative to the top surface of the frame; providing a multiplicity of orientation units, and spatially positioning the respective orientation units in predetermined locations within the internal cavity of the frame, and wherein the respective orientation units each include an elongated, generally cylindrically shaped, and selectively, mechanically moveable, actuator which supports, at least in part, a discrete region of the object of interest which is positioned on the frame; providing a gantry, and moveably mounting the gantry for travel along a first path of travel relative to the frame, and in predetermined, spaced relation relative to the top surface of the frame; moveably mounting a cutting device on the moveable gantry, and rendering the cutting device selectively moveable along a second, predetermined path of travel which is transverse to the first predetermined path of travel; positioning a plurality of sensors on the frame and/or moveable gantry, and sensing, with the respective sensors, the vertical and horizontal position of at least one of the regions of the object of interest which is supported on the frame; providing a controller, and controllably coupling the controller to each of the multiplicity of orientation units; the moveable gantry; the cutting device, and the respective sensors; sensing with the sensors the horizontal and vertical position of the object of interest, and supplying the horizontal and vertical position of the object of interest to the controller; selectively energizing the respective orientation units, by way of the controller, to adjustably effect, and then maintain the position of the object of interest in the given, predetermined planar orientation on the frame by selectively moving the actuator of individual orientation units so as to impart force to the object of interest, and thereby position the object of interest in the predetermined planar orientation; controllably propelling the gantry along the first course of travel to a given location as determined by the controller; controllably propelling the cutting device along the second course of travel to a given region of the object of interest which is to be severed, as determined by the controller; controllably withdrawing, by means of the controller, the actuator of individual orientation units which are supporting the object of interest, and which are further located in a predetermined vicinity of the region of the object of interest which is to be severed, and positioning the respective actuators in spaced relation relative to region which is to be severed; selectively and operably energizing the cutting assembly by way of the controller, and severing the object of interest in a predetermined pattern in the region of the object of interest as determined by the controller by simultaneously, and controllably propelling the gantry along the first course of travel, and the cutting assembly along the second course of travel; and after the step of severing the object of interest, selectively, and controllably repositioning, by means of the controller, the actuator of individual orientation units which were previously withdrawn, and located in spaced relation relative to the region of the object of interest which was previously severed, so as to maintain the object of interest in the predetermined planar orientation relative to the frame.

The present invention 10 includes a plurality of sensors 50 which may be mounted either on the frame 51, or on the movable gantry 52. The frame mounted sensors 51 are typically operable to emit an optical beam 53 which determines the horizontal orientation of the top surface 13, of the continuous sheet 12 as it rests upon the frame 20. Still further, the gantry 30 mounted sensors 52 are typically rendered operable to emit an optical beam 54 which determines the vertical orientation of the top surface 13 of the continuous sheet 12 that rests on the frame 20. While two sensors 51 and 52 are shown, it should be understood that multiple sensors will be deployed in various locations both on the frame 20, as well as the movable gantry 30 so as to provide information to a controller, as will be described, hereinafter, regarding the precise planar orientation 17 of substantially the entire upwardly facing surface area 13 of the continuous sheet 12 as it rests on the frame 20.

The respective orientation units 60 each include a drive sleeve which is generally indicated by the numeral 90. The respective drive sleeves 90 each have a generally elongated and cylindrically shaped main body 91 which has a reduced cross-sectional dimension which permits the drive sleeve 90 to be telescopingly, and rotatably received within the cylindrically shaped internal cavity 83, and which is defined by the cylindrically shaped housing 80. The elongated main body 91 has a first end 92 which mounts a coaxially aligned drive shaft 93. The drive shaft 93 is received through the passageway 85 which is formed in the end plate 84 of the cylindrically shaped housing 80. Still further, this drive shaft 93 is then releasably secured within the drive shaft coupler 74. This coaxially orients the drive shaft 73 with the drive shaft 93. Consequently, an energizing of the electrical motor 70, and which causes a corresponding rotation of the drive shaft 73, imparts a corresponding coaxial rotation relative to the drive shaft 93. This simultaneous rotation of the drive shaft 93 imparts coaxial rotational movement of the elongated main body 91 within the cylindrically shaped internal cavity 83. The drive sleeve 90 has a second end 94, and a cylindrically shaped internal cavity 95 is defined by the elongated main body 91, and extends from the second end 94, in the direction of the first end 92. The cylindrically shaped internal cavity 95 has a given cross-sectional dimension. Still further, and as seen in

The method 200 of the present invention includes another step 210 of providing a gantry 30, and movably mounting the gantry 30 for travel along a first path of travel 34 relative to the frame 20, and in predetermined, spaced relation relative to the top surface 13 of the frame 20. The method 200 further includes another step 211 of movably mounting a cutting device 40 on the movable gantry 30, and then rendering the cutting device selectively movable along a second, predetermined path of travel 41 which is transverse to the first predetermined path of travel 34.

The method 200 includes still another step 215 of selectively energizing the respective orientation units 60 by way of the controller 120, to adjustably effect, and then maintain, the position of the object of interest 11 in the given predetermined planar orientation 17 on the frame 20 by selectively moving the actuator 100, of individual orientation units 60, so as to impart force to the object of interest 11, and thereby position the object of interest 11 in the predetermined planar orientation 17. The method 200 of the present invention includes another step 220 of controllably compelling the gantry 30 along the first course of travel 34 to a given location as determined by the controller 120. The method 200 of the present invention includes another step 221 of controllably propelling the cutting device 40 along the second course of travel 41 to a given region 43, of the object of interest 11, and which is to be severed as determined by the controller 120. The method 200 of the present invention includes another step 222 of controllably withdrawing by means of the controller 120, the actuator 100 of the individual orientation units 60, and which are supporting the object of interest 11, and which are further located in a predetermined vicinity of the region 43 of the object of interest 11 which is to be severed, and positioning the respective actuators 100 in spaced relation relative to the region 43 which is being severed.

Further, the method 200 of the present invention includes another step 224, which occurs after the step of severing the object of interest, of selectively and controllably repositioning, by means of the controller 120, the actuator 100 of selective, individual orientation units 60 which were previously withdrawn, and located in spaced relation relative to the region 43 of the object of interest 11 which was previously severed, so as to maintain the object of interest 11 in the predetermined planar orientation 17 relative to the frame 20.
The method 200 of the present invention, as described, above, further includes another step 230 of providing a selectively energizable electric motor 70 which is controllably coupled to the controller 120, and which further has a selectively rotatable drive shaft 73. The method 200 further includes another step 231 of providing a cylindrically shaped housing 80, having opposite first and second ends 81 and 82, in a coaxially orientation relative to the to the drive shaft 73, and wherein the cylindrically shaped housing 80 further defines a cylindrically shaped internal cavity 83 which extends between the first and second ends thereof.

The operation of the present invention is believed to be readily apparent and is briefly summarized at this point.
In its broadest aspect, the present invention relates to an apparatus 10 for supporting and severing an object of interest 11, and which includes providing a frame 20 for positioning the object of interest 11 which is to be severed, in a given, predetermined, planar orientation 17. The apparatus 10 further includes, in its broadest aspect, a cutting device 40 which is selectively, and movably mounted in spaced relation relative to the frame 20, and which further, when rendered operable, severs the object of interest 11 which is positioned in the predetermined, planar orientation 17, on the frame 20. The apparatus 10 in its broadest aspect also includes a multiplicity of orientation unit 60 which are mounted on the frame 20, and which are further selectively, and mechanically adjustable, as to length, so as to individually position, and maintain, the object of interest 11 to be severed, in the predetermined, planar orientation 17, while being severed. Further, and in its broadest aspect, the present invention 10 includes a controller 120 which is operably coupled with each of the cutting device 40, and the multiplicity of orientation units 60, so as to effect an optimal severing of the object of interest 11, while maintaining the object of interest 11 in the predetermined planar orientation 17 on the frame 20, and which further, simultaneously and selectively displaces the individual orientation units 60 from a supporting position relative to a region 43 of the object of interest 11, and where the cutting device 40 is currently severing the object of interest 11.
As noted above, the apparatus 10 includes a frame 20 which further has top and bottom surfaces 22 and 23, respectively, and which is further defined, at least in part, by a peripheral sidewall 21. The frame 20 defines an internal cavity 24, and which is further located between the top and bottom surfaces 22 and 23, of the peripheral sidewall 21. The multiplicity of orientation units 60 are mounted in a predetermined pattern within the internal cavity 24 of the frame 20, and are further positioned between the peripheral sidewalls 21, of the frame 20.
As seen in the drawings the apparatus 10 of the present invention further includes a plurality of sensors 50, which are mounted on the frame 20, and which are further rendered operable to sense the given planar orientation 17 of the object of interest 11, as it rests on the frame 20, and is positioned between the frame 20 and the cutting device 40, respectively. Still further, it should be understood that the plurality of sensors 50, in one form of the invention, are optical sensors, and which sense the horizontal and/or vertical position of the object of interest 11, and which is located on the frame 20, and located in the given planar orientation 17. In another possible form of the invention the plurality of sensors may include both optical, as well as mechanical sensors for performing the same task. As seen in the drawings, and in one form of the invention, the apparatus 10 includes a gantry 30, which is borne by the frame 20, and which further is selectively movable along a predetermined, first course of travel 34 relative to the frame 20. The cutting device 40 is mounted on the gantry 30, and is further, selectively movable along the gantry 30, and in a predetermined second course of travel 41 which is transverse to the first course of travel 34 of the gantry 30. The cutting device 40, when rendered operational, severs the object of interest 11 which is located on the frame 30, and is positioned between the frame 30, and the cutting device 40, which is mounted on the gantry 30. The controller 120 is operable to control the position of each of the gantry 30, and the cutting device 40, and which is further selectively movable along the gantry 30 so as to facilitate the severing of the object of interest 11 in a given pattern as provided by electrical signal or other instructions received from the controller 120. The apparatus 10 of the present invention, and more specifically the orientation units 60, thereof, include a selectively energizable electric motor 70 which is controllably coupled to the controller 120, and which further has a selectively rotatable drive shaft 73. In this regard, the respective orientation units 60 further includes a cylindrically shaped housing 80 which has opposite, first and second ends 81 and 82, respectively, and which is further coaxially oriented relative to the drive shaft 73. The cylindrically shaped housing 80 further defines a cylindrically shaped internal cavity 83 which extends between the first and second ends 81 and 82, thereof. The respective orientation units 60 further include a drive sleeve 90 which is telescopingly and rotatably received within the internal cavity 83 of the cylindrically shaped housing 80. The drive sleeve 90 has a first end 92 which is drivingly coupled to the drive shaft 73 of the selectively energizable electric motor 70, and an opposite second end 94. The drive sleeve 90 further defines a cylindrically shaped internal cavity 95 extending from the second end 94, and in the direction of the first end 92 thereof. The drive sleeve 90 further defines an internal screw thread 96 which is oriented within the cylindrically shaped internal cavity 95. As should be understood, upon a selective energizing 233 of the selectively energizable motor 70, the drive sleeve 90 coaxially rotates in a predetermined direction within the internal cavity 83 of the cylindrically shaped housing 80. As should be further understood from a study of the drawings, the respective orientation units 60 each further include an elongated, generally cylindrically shaped actuator 100 having opposite first and second ends 101 and 102, respectively, and which further has an exterior facing surface 103, and which additionally defines an outwardly facing screw thread 104. The screw thread 104 further matingly and threadably cooperates with the internal screw thread 96 which is defined by the drive sleeve 90. As will be appreciated, and as earlier discussed, a predetermined rotation of the drive sleeve 90 by the selective energizing 233 of the electric motor 70, is effective in screw-threadably moving or otherwise urging the elongated actuator 100 either coaxially outwardly 106, or coaxially inwardly 107, relative to the drive sleeve 90 so as to change an overall length dimension of the orientation unit 60.
As described in the paragraph immediately, above, the elongated, cylindrically shaped actuator 100 has a predetermined maximum cross-sectional dimension, and the apparatus 10 further includes an object engaging member 110 which is mounted on the second end 102, of the elongated cylindrically shaped actuator 100. The object engaging member 110 has a cross sectional dimension which is greater than the cross sectional dimension of the elongated, cylindrically shaped actuator 100. Still further, and in one possible form of the invention, the object engagement member 110 is rotatably movable relative to the second end 102 of the elongated cylindrically shaped actuator 100. This feature prevents friction related damages from occurring upon rotation of the elongated cylindrically shaped actuator 100. It should be understood the respective orientation units 60 are spaced, one from another, at a distance of about ______ to about ______ inches.
More specifically the present invention 10 relates to an apparatus for supporting and severing an object of interest 11, and which includes a frame 20 for positioning an object of interest 11 which is to be severed in a given planar orientation 17. The apparatus further includes a gantry 30 which is borne by the frame 20, and which is selectively movable along a predetermined, first course of travel 34 relative to the frame 20. In one form of the invention the present apparatus 10 includes a cutting device 40 which is mounted on the gantry 30, and which is further selectively movable along the gantry, and in a predetermined, second course of travel 41, which is transverse to the first course of travel 34, of the gantry 30. The cutting device 40, when rendered operational, severs the object of interest 11 which is located on the frame 20, and positioned between the frame 20, and the cutting device 40 which is movably mounted on the gantry 30. It should be understood that the present apparatus 10 includes a plurality of sensors 50 which are mounted on the frame 20, and which are further rendered operable to sense the given planar orientation 17 of the object of interest 11, relative to each of the frame 30, and the cutting device 40, respectively. Still further, the present apparatus 10 includes a multiplicity of orientation units 60 which are mounted on the frame 20, and which are further selectively adjustable, as to length, so as to individually position, and maintain the object of interest 11 to be severed in the predetermined planar orientation 17 while being severed. Still further, the invention 10 includes a controller 120 which is operably coupled with each of the movable gantry 30, cutting device 40, respective sensors 50, and multiplicity of orientation units 60, so as to effect an optimal severing of the object of interest 11 while maintaining the object of interest in the predetermine planar orientation 17 on the frame 20, and simultaneously withdrawing 222 individual orientation units 60 from a supporting orientation relative to a region 43 of the object of interest 11 where the cutting device is severing the object of interest 11 (
Therefore, it will be seen that the present apparatus and method for supporting and severing an object of interest provides many conveniences and advantages which are not provided by the prior art devices and methodology which have been employed, heretofore, in the severing of objects of interest such as sheet material as is illustrated, and described in the present application. The present invention is easy to operate, convenient, reliable, and provides resulting precision cuts in objects of interest 11 which have not been achievable using the prior art teachings and devices known, heretofore.
In compliance with the statute the invention has been described in language more or less specific as to structural and methodological features. It is to be understood, however, that the invention is not limited to the specific features shown, and described, since the means herein disclosed comprise preferred forms of putting the invention into effect.
