Definitions

  • the invention relates to a transport device according to the preamble of claim 1 or 2.
  • DD-C-41 141 discloses such a device for guiding needles, wire shafts and the like to machining tools, in particular grinding and polishing tools for removing the embossing burr which is formed during the embossing and punching of the ear area.
  • the workpieces are moved transversely to their longitudinal axis by means of an elastic circumferential conveyor belt, on which two or more jaws having elastic clamping devices are riveted at intervals, which open and close automatically when the conveyor belt is deflected for receiving and dispensing the workpieces and then clamped the workpieces guide past the tools.
  • the clamping devices are loaded and emptied by means of a feed or ejection device. Spring elements are also provided so that the workpieces maintain the correct working position during feeding into the clamping devices.
  • the workpieces to be machined can only be continuously moved past the machining tools for the grinding or polishing process, the elastic conveyor belt giving way to the workpieces due to the machining pressure of the tools. A precise and step-by-step approach of the parts is therefore not possible. Furthermore, the jaws of the clamping device must be adapted in shape and size to the respective workpiece.
  • the invention is therefore based on the object of providing a transport device which can be used as universally as possible and with which wire pieces which lie within a specific, as large as possible diameter and length range, with one and the same transport means, can intermittently and quickly successively position one or more processing stations arranged next to one another. and can be fed precisely.
  • the parallel runs of two toothed belts can thus be arranged so that their teeth are directed towards each other, i.e. Tooth on tooth shows, that is, the belts run in mirror image to each other, or the teeth of one or the other strand can run somewhat longitudinally offset, possibly so that the teeth of one strand lie over the tooth gaps of the other strand.
  • Tooth on tooth shows, that is, the belts run in mirror image to each other, or the teeth of one or the other strand can run somewhat longitudinally offset, possibly so that the teeth of one strand lie over the tooth gaps of the other strand.
  • both strands run in a parallel position, i.e. the parallel toothing of both strands e.g. point upward. (In all four cases, the vertical belt spacing should be adjustable.)
  • the toothed belts are placed against each other so that the wire pieces are held tightly against the other toothed belt by one tooth flank of at least one toothed belt during transport.
  • the elongated workpieces can be quickly and accurately transported with one type of belt for all wire piece diameters that lie within the working area of a machining or processing machine.
  • the transport device according to the invention makes it possible for the transport device according to the invention to be used, for example, in a device for producing precision wire pencils with an exactly precise wire pin head shape and size, as are required for further use in automatically operating nailing devices for trouble-free functioning of these devices. Furthermore, it could also be part of a device for producing workpieces, the upsetting processes in several steps, e.g. in multi-stage presses. In this case too, the transport device according to the invention works so precisely that the raw parts to be machined maintain the working position securely and immovably through all of the deformation stations arranged next to one another (1 clamping device with upsetting device each). The device can therefore be used wherever a precise step-by-step transport process is important.
  • the invention thus also relates to the use of a transport device according to the invention in a wire-processing machine for producing machined wire pins, in particular head nails.
  • the toothed side of the upper toothed belt (12) points downwards.
  • the upper guide (14) is firmly screwed into two identically designed holders (20) which are height-adjustable in slots.
  • the holders (20) are attached to the machine body (24).
  • the strand of the toothed belt (12) shown is deflected upwards by means of a plurality of toothed and / or smooth disks, not shown, which are arranged at one end of the guide (14) and in the vicinity thereof.
  • the upper horizontal run of a second endless, lower toothed belt (28) is guided with the toothed side pointing upwards in a guide (30) of the same design corresponding to the guide (14). This strand is diverted downwards.
  • the guide (30) is fastened in holders (32), which are also adjustable in height.
  • the endless toothed belts (12 and 28) can either via a gear transmission and the toothed or deflection pulleys jointly by a motor-driven stepping transmission, or, depending on the desired transport speed, jointly by a controllable servo motor, or separately, each by a controllable servo motor same direction, which corresponds to the desired direction of transport, are driven intermittently.
  • a clamping device e.g. B. a device for producing wire pins arranged.
  • a tool holder 46) of the front part (40 or 42) of each lever or slide, an identically designed, jaw-like clamping tool (48) for clamping a wire pin blank (52) is adjustably fastened.
  • an upsetting tool (60) of an upsetting device of the aforementioned device for forming a head (54) on the wire pin blank (52) is also indicated.
  • the upsetting tool (60) is arranged in the center of the toothed belt pair (12, 28) in front of the clamping tools (48).
  • the machine body (24) is provided with a trapezoidal groove (26) over the entire length of the transport path so that the pin blanks (52) and the finished wire pins (58) can be transported through.
  • each lever (66 and 68) of a wire cutting device (70) of the device for producing wire pins is pivotably mounted in a common bearing (64).
  • the two guides (14 and 30) end a short distance to the right in front of the cutting tools (72), while the lower and upper runs of the toothed belts (12 and 28) extend slightly beyond the cutting tools (72) before both runs go up or redirected downwards.
  • the length of the guides (14 and 30) on the right side of the device in Fig. 1 depends on the number of work stations arranged side by side for the clamping and upsetting operations and on the way in which the pins produced are removed.
  • a feed not shown, but known pulls the wire from the coil of wire through a straightening apparatus and pushes as much wire (out of the drawing plane in FIG. 1) through the opened cutting tools (72) and the lower or upper run of the toothed belt (12 and 28) through, as required for the desired wire pin length and for shaping the wire pin head.
  • the intermittent drive of the pair of toothed belts (12, 28) stands still during insertion into the two belt spaces and cutting off the wire.
  • the intermittent drive is then briefly switched on again and the pair of toothed belts (12, 28) is moved further, for example by four teeth in the exemplary embodiment, and stopped again for a new wire feed. This happens until a cut-to-length pin blank (52) comes to rest between the clamping jaws (48) of the clamping device (44).
  • the wire to be cut to length can now be inserted according to FIG. 3 or 4 into tooth gaps (76 and 78) of the teeth (80 and 82) of the toothed belts (12 and 28) facing one another, or according to FIG. 5 into a tooth gap (78) of the upper run of the Toothed belt (28) and on the tooth head (86) of a tooth (80) of the run of the upper toothed belt (12) are inserted, or, depending on the relative longitudinal arrangement of the toothed belt (12 and 28), in a tooth gap (78) of the run of the lower toothed belt (28) and against the toothed belt back (84) of the run of the upper toothed belt (12) are inserted (FIG. 6).
  • pins with a different wire diameter are to be manufactured and transported, all that is required is the distance between the two parallel strands by moving the holders (20 and 32) towards one another or apart. to be changed.
  • the guides (14 and 30) are also moved. See sub-figures a and b of FIGS. 3 to 6. If the change in wire diameter exceeds the range that can be covered with this belt arrangement according to FIG. 3, the toothed side of the upper toothed belt (12) is turned upward, so that the teeth (80 and 82) of the two belts (12 and 28) now point in the same direction, namely upwards (Fig. 6). This allows pins with an even smaller wire diameter to be transported safely.
  • the pin blanks (52) are then pressed by the tooth heads (86) of the teeth (80) of the upper toothed belt (12) against the adjacent tooth flanks of the teeth (82) of the lower toothed belt (28).
  • the pin blanks (52) are clamped between two adjacent tooth flanks of the teeth (80 and 82) of the two toothed belts (12 and 28).
  • the toothed belts (12 and 28) are also guided laterally immovably over the transport path.
  • the pin blanks (52) are guided and held precisely, transported step by step, between the clamping tools (48) of the clamping device (44), with a short wire end, which is required to form the wire pin head (54), in FIG. 2 protrudes to the right from the clamping tools (48). Then the clamping tools (48) close and hold the pin blank (52) until the upsetting tool (60) has upset the head (54), the clamping tools serving as an anvil. After the clamping tools (48) have opened again and the upsetting tool (60) has taken its rear position, the finished pin (58) is moved one step further out of the tool area, while a new pin blank gets between the tools (48, 60) and the process begins again. After a few transport intervals, the finished pins (58) fall out safely via a chute at the end of the straight transport route without an additional ejector, or the orderly arriving finished pins can also be removed and removed individually for storage or other processing.
  • clamping and upsetting devices could also be arranged next to one another between the clamping and upsetting device and the point of failure of the finished pin, if the machining or processing the wire blanks must be carried out in several upsetting stages.
  • the carriage (112), shown in its front working position in FIG. 7, has a dovetail guide over its entire length and is slidably mounted between two guide strips (132) on a base plate in the machine frame (136).
  • a threaded flange (140) with an internal thread is fastened to the slide (112), in which a set screw (142) is screwed in, which is countered by means of a ring nut (144).
  • a compression spring-loaded compression tool (154) of the compression device (114) is arranged in a separate guide (148) in bearing bushings and can be moved in a longitudinal manner, with sliding bearings.
  • the guide (148) with the floating upset tool (154) is fastened to the machine frame (136) in an easily removable or replaceable manner by means of two stud bolts (166). Thanks to a return spring, the compression tool (154) is permanently non-positively on the hexagon head of the set screw (142). Also in the extension of the axis of the upsetting tool (154), two clamping tools (176) of a clamping device (178) of the device for producing wire pins (182) are arranged in the immediate vicinity in front of it and symmetrically to this axis, each of which acts in a lever or slide . 7, a wire pin (182) with an upset head (184) is firmly clamped between the clamping tools (176).
  • the shaft of the wire pin (182) protruding from the clamping tools (176) in FIG. 7 lies, firmly clamped, in the tooth gaps of two Toothed belt as a transport belt of a transport device of the device for producing wire pins shown in FIG. 7 above.
  • the pin blanks (186), which still have no head (184) are intermittent, in the horizontal and vertical plane, exactly in the middle in front of the upsetting tool (154) of the upsetting device (114) brought up and away from it.
  • the toothed belts (e.g. 192) move gradually across the compression and clamping direction of the compression and clamping device (114,178).
  • a height-adjustable guide rail of which only the lower one (198) can be seen, the distance of the toothed belts from one another, and thus the tension with which the pin blanks (186) are held in the tooth gaps, can be adjusted.
  • the toothed belts are also moved laterally, immovably, over the transport route.
  • a bearing (202) is attached to the front part of the guide of the carriage (112), in which a rocker arm (206) is mounted on bolts (204).
  • a connecting rod (210) engages on a bolt (208), which connects the rocker arm (206) on the one hand to the slide (112) of the upsetting device (114) via a bolt (212) or on the other hand couples a tool holder (214) to a positioning device (216) for the pin blanks (186) via bolts (218).
  • the connecting rods (210) have two joint heads (220, 222) which are connected to one another by means of a turnbuckle (224).
  • the tool holder (214) is guided in a longitudinally movable manner in the machine frame (136) by means of two rods (226) lying one below the other.
  • a positioning tool (232) with four working surfaces (234 to 240) is arranged on the holder (214) for a 4-stage positioning process, during which the longitudinal position of the pin blanks (186) can be changed.
  • This positioning tool (246) is provided with only two working surfaces (248 and 250) for axially displacing the pin blanks (186) against the direction of displacement of the first positioning tool (232).
  • the mode of operation of the transport device described above is as follows when it is part of a device for producing wire pins, which is partially shown in FIG. 7:
  • a feed not shown, but known pulls the wire (254) from the wire supply through a straightener and pushes as much wire through the opened cutting tools (252) and into the tooth gaps of the two toothed belts (e.g. 192) as for the desired wire pin length and Forming the wire pin head (184) is required.
  • the cutting tools (252) which act against one another and can each sit in a lever or in a carriage, cut off the wire (254), a pyramid-shaped wire pin tip (188) being produced.
  • the intermittent drive of the pair of toothed belts stops for a short time. Then the drive is switched on again for a short time, thereby moving the pair of toothed belts one step further and stopping again before a new wire feed (this could also be done by a stepping gear). This happens until a cut pin blank (186) comes to rest between the clamping tools (176) of the clamping device (178) and in the middle in front of the upsetting tool (154) of the upsetting device (114).
  • the cutting tools (252) of the cutting device and the clamping and upsetting device (178, 114) of the device for producing wire pins (182) are arranged stationary to compensate for this the different distance from the wire pin tip (188) to the upsetting tool (154) in the manufacture of a different pin length is compensated for by shifting the pin blanks (186) in their longitudinal direction within the transport path between the cutting station and the head upsetting station, as follows:
  • the positioning of the pin blanks (186) is carried out by the two positioning tools (232 and 246) of the positioning device (216), the first tool (232) having its four working surfaces (234 to 240) for a gradual feed. The gradual positioning takes place with each advance stroke of the slide (112).
  • the positioning tool (232) guided in the machine frame (136) is moved towards the transport device via the connecting rod (210) and the rocker arm (206), so that the pin blank (186) located at the time in front of the first working surface (234) of the positioning tool (232) is advanced by a certain amount.
  • the transport device stands still during this process. While the carriage (112) is running back, the drive is briefly actuated for a transport interval, so that the pin blank (186) previously moved from the working surface (234) of the tool (232) is now in front of the second working surface (236) and at one renewed upsetting is advanced by the same amount.
  • the pin blank (186) has been moved from the fourth working surface (240) of the positioning tool (232) to its foremost position. In this longitudinal position, the pin blank (186) is gradually transported in the direction of the upsetting station until it comes to rest in front of the working surface (250) of the second positioning tool (246). Also derived from the compression movement of the carriage (112), the pin blank (186) is possibly moved back a short distance from the work surface (250), as a result of which the length tolerances of the pin blanks are compensated for so that it has reached its final position, and he comes after the two transport intervals between the clamping tools (176) that exactly such a large wire end protrudes from the clamping jaws (176) as is required to form the wire pin head (184). In the case of longer pin blanks (186), they are moved back by the second positioning tool (246) in two steps, in such a way that the pin blanks are first moved back from the work surface (248) and then from the work surface (250) to the final position.
  • the positioning device (216) can be dispensed with entirely if only pins of a length order are to be produced, or if no such high pin quality is required.
  • the cutting device is then arranged in such a way that the pin blanks (186) come to rest in the transport device such that just such a wire end protrudes from the clamping tools (176) as is required for the head production during the upsetting process.
  • the drive shaft is set in motion, which gives the carriage (112) a reciprocating movement.
  • a finished wire pin (182) is moved out of the tool area, while a new pin blank (186) gets between the tools (154 and 176), whereupon the process begins again.
  • the finished pins (182) fall out safely via a slide at the end of the transport route without an additional ejector, or they can be ordered incoming finished pens for magazine or other processing can also be automatically removed and removed individually.
