Definitions

  • This invention relates to a machine for cutting templates off a sheet material.
  • cardboard templates are employed whose contour shape provides a reference contour shape or profile for making shoe uppers.
  • the cardboard templates are formed from cardboard sheets which are cut according to desired shapes using suitable cutting machines.
  • Some cutters employ a small knife, or alternatively a laser beam, for the cutting operation which works from one side only of the cardboard sheet.
  • the knife which interacts with an anvil plate supporting the cardboard sheet, can only cut, however, thin cardboard sheets, whereas for uppers making, a fairly stiff cardboard template is preferred, and accordingly, this would have to be cut from cardboard of some thickness.
  • the use of a laser beam involves high equipment costs and leaves burning marks around the edges of a cardboard template; in addition, cardboard sheets of some thickness require a laser beam of comparatively high power, which aggravates equipment costs.
  • More effective machines than the ones mentioned above are those employing an upper tool and lower mating tool, with the cardboard to be cut being fed in the nip therebetween.
  • the tool and mating tool are movable jointly across a cutting plane and usually consist of a punch and die, respectively.
  • the last-mentioned machines do provide a neat and fast cut through the cardboard sheet.
  • the tool and mating tool are mounted on a C-like structure which interconnects them, and specifically mounted on the ends of the opposing sides of the C-like structure forming holding arms.
  • Such a connecting structure ensures that the tool and mating tool will move jointly with relatively high and consistent mechanical accuracy, that is, that no relative misalignment of the tool and the mating tool will occur.
  • the largest size of the processable cardboard sheet is tied in with the length of the arms of said C-like structure. Consequently, in order to cut from large size cardboard sheets, the C-like structure must be considerably extensive. This implies that the C-like structure, and hence the machine, become intrusive and very heavy; in addition, the C-like structure may tend to possess inadequate rigidity to provide said accurate joint movement of the tool and mating tool.
  • a machine for cutting templates off a sheet material which employs for the cutting a tool and a mating tool jointly movable across a cutting plane in the nip whereof the sheet material to be cut is fed, characterized in that the tool and mating tool are mounted on separate holding means, and that synchronized motion drive means control the joint movement of said holding means.
  • the machine generally shown in Figure 1 at 10 comprises a structure 11 which carries all the components of the machine 10.
  • Two webs 12 extend vertically from the supporting structure 11.
  • an upper carriage 15 holding a punch 16 is mounted on the upper bar 13 and the upper screw 14 .
  • the carriage 15 is provided with a bush 17 fitted over the upper bar 13 in a freely slidable manner, and a bush 18 fitted over the upper screw 14.
  • bush 18 has an internal nut 19 which engages with the upper screw 14, with the interposition of balls 20 arranged to circulate in a closed loop path within the bush 18.
  • the carriage 21 has a bush 24 fitted over the lower bar 13 in a freely slidable manner and a bush 25 fitted over the lower screw 14.
  • the bush 25 has an internal nut, not shown, which engages with the lower screw 14, with the interposition of balls arranged to circulate in a closed loop path within the bush 25.
  • the two screws 14 are interconnected rotatively by two identical gear wheels 26 in mutual mesh engagement, being each unitary with one end of a respective one of screws 14.
  • the gear wheel 26 connected to the lower screw 14 is unitary with a cogged pulley 27 which is driven by an electric motor 28.
  • the drive connection of the electric motor 28 to the cogged pulley 27 is provided by a pinion pulley 29 being unitary with the shaft of the motor 28 and a cogged drive,belt 30 which is trained around the pinion pulley 29 and the cogged pulley 27.
  • FIG. 3 Detailed in Figure 3 is the drive mechanism for the punch 16.
  • This mechanism which is mounted on the upper carriage 15, comprises a camming device 31 driven by an electric motor, not shown and also mounted on the carriage 15.
  • the device 31 drives of rotary reciprocating motion a lever 33 via a rod 32 of the device.
  • the lever 33 transfers this motion to a rod 34 whereto a connecting rod 35 is pivoted; the connecting rod 35 is also pivoted to a rod 36 lying parallel to rod 34, being in turn pivoted on the body of carriage 15, thereby forming an articulated quadrilateral comprised of the body of carriage 15, the two rods 34, 36, and the connecting rod 35.
  • the connecting rod 35 is driven of linear reciprocating motion.
  • Attached to the bottom end of the connecting rod 35 is a head 37 firmly holding the punch 16.
  • Each screw 38 is journalled with one end on a wall 42 of the structure 11, and has a bevel gear 43 affixed to the other end.
  • the two bevel gears 43 are identical with each other and enmesh with two more bevel gears 44 ( Figure 2), also identical with each other, which are rigidly interconnected by a shaft 45 perpendicular to the screws 38.
  • the shaft 45 is driven by an electric motor 46, and to this aim, the drive connection between the motor 46 and the shaft 45 is established by means of a pinion pulley 47 rigid with the shaft of the motor 46, a cogged pulley 48 rigid with shaft 45, and a cogged drive belt 49 which is trained around the pinion pulley 47 and the cogged pulley 48.
  • the pinion 47 and pulley 48 are positioned on the same web 12 of the structure 11 which mounts pinion pulley 29 and cogged pulley 27.
  • the clamp 40 is actuated by two electric motors 50.
  • the actuation of clamp 40 is detailed in Figures 4, 5, where reference is made to the movement brought about by one of the two motors 50, the other being quite identical and synchronous.
  • the clamp 40 comprises a fixed jaw 51 and a moving jaw 52.
  • the moving jaw 52 is connected to the motors 50, and for the purpose, each motor 50 is provided with a lever 53, pivoted at 54 on the holder 39; attached to one end of the lever 53 is the moving jaw 52, whereas to the other end of the lever 53 there is drivingly connected a rod 55 driven by motor 50.
  • Each motor 50 is thread coupled to its respective actuating rod 55 such that a rotation of the motor will produce a linear displacement of the rod 55.
  • This machine 10 operates as follows.
  • Motors 50 are first operated to extend the rods 55, thereby the lever 53 will be pivoted in a counterclockwise direction and the moving jaw 52 raised off the fixed jaw 51 of the clamp 40, as shown in Figure 4.
  • the cardboard sheet is then passed as shown in phantom lines at 56, until a strip of a selected size is brought past the jaws 51, 52; thereafter, the motors 50 are again operated, in the reverse direction, to bring jaw 52 back down and clamp the cardboard sheet 56 between the jaws, 51 and 52, as shown in Figures 4 and 5.
  • the cardboard strip bears onto a deck 57 made of a flexible material which is anchored with one end on the structure 11, at the location of the punch 16 and the die 22, and is wound with the other end around a rotatable roller 58.
  • Motor 46 rotates pinion pulley 47, and hence cogged pulley 48 through the drive belt 49.
  • the rotation of the pulley 48 results in rotation of the shaft 45 with the bevel gears 44, and accordingly, joint rotation of bevel gears 43 and the screws 38.
  • the joint rotation of the screws 38 causes the holder 39 to traverse, because of said screws 38 engagement with the nuts in the bushes 41 provided on the holder 39.
  • the holder 39 will run along the screws 38 in a straight direction designated "Y" in Figure 1, perpendicularly to said direction "X"; consequently, the clamp 40, carried in the holder 39, will traverse along said direction "Y".
  • the motor driving the camming device 31 produces, as explained hereinabove, linear reciprocation of the connecting rod 35, and hence of the punch 16 attached to the head 37 carried on the connecting rod 35.
  • the punch 16 is reciprocated between a top end-of-travel position where it is removed from the die 22, and a bottom end-of-travel position where it penetrates a bore 23 in the die 22.
  • the die 23 may be rotated manually where required to bring to registry with the punch 16 another bore 23, because the former bore can no longer serve its function.
  • the clamp 40 takes the strip of sheet cardboard 56 to a location below the punch 16 which, on being moved, will perforate the cardboard.
  • the motors described in the foregoing are preferably controlled from an electronic microprocessor control unit.
  • the cardboard sheet can be passed unrestrictedly between the punch 16 and the die 22 along its entire length and across its full width, whereas with the C-like supporting structure, the cardboardsheet movements are constrained by the structure upright joining its two arms.
  • the machine 10 can cut off cardboard sheets twice the size of those to be cut on machines the same size as this machine 10 but having a C-like structure.
  • the movements of the carriages 15 and 21 are accomplished using few and inexpensive elements.
  • the screws 14, additionally to performing the functions of drive members, also serve as guide members for the carriages 15 and 21.
  • the operation of the clamp 40 is also accurate, reliable, and straightforward, by virtue of the screws 38, the screw/nut fit with intervening circulating ball bearings, and the other drive members described.
  • the bearing deck 57 which defines a cutting plane, would unwind from the roller 58 as the clamp 40 moves away from the punch 16 and the die 22, and wind back onto the roller 58 as the clamp 40 moves closer to the punch 16 and the die 22.
  • This bearing deck 57 is quite effective to support the cardboard sheet during the perforation step and to prevent cardboard cuttings from falling to the lower portion of the machine.
  • the holding means comprising the carriages 15 and 21 may be replaced with equivalent holding means adapted to hold the punch and die and to be driven synchronously.
  • the synchronized drive means for the carriages 15 and 21, comprising motor 28, pinion pulley 29, drive belt 30, cogged wheels 26, 27, screws 14, and carriage bushes 18, 25, may also be replaced with equivalent drive means using drives with equivalent functions, although the embodiment herein described and illustrated shows to be specially advantageous, as explained in the foregoing.
  • the drive screws 14 and their gear wheels 26 may be sized (thread pitch, number of the teeth on the gears, diameters, etc.) differently from each other, provided that they can produce a joint movement of the punch and the die.
  • the two carriages could be driven by means of two separate motors, and the joint movement of the carriages achieved by means of position sensors supplying the control unit with information about the carriage positions, thereby his unit can control the operation of the two motors in a suitable way to synchronize the movements of the two carriages.
  • the rollable bearing deck 57 may be replaced with a fixed table, although the rollable one is apt to simplify the machine construction.
  • the machine motors need not be electric ones, and they could be hydraulically, pneumatically, or otherwise operated.
  • the machine of this invention can cut templates for any applications off a sheet of any material, such as sheet plastics or metal in addition to cardboard.
  • the punch and die may be replaced with any other tool and mating tool effective to cut through sheet material.
