Description

In the present invention, relating to machines for inserting hooks and rings in shoe blanks, a lever strut associated with a counter that records the number of hooks and spikes inserted is used to set the hook and ring matrices in place.

To change the position of the workpiece when inserting hooks and rings in the machine, a movable stop is used, which is connected by means of a gear with a lever-strut.

In another form, the same machine, being somewhat modified, is used to process two blanks in one pass.

In FIG. 1 shows a front view of a car; FIG. 2 is a side view of it; FIG. 3-plan; FIG. 4 and 5 parts; FIG. b-view of the workpiece with inserted hooks and rings; FIG. 7 — another form of machine execution — front view; FIG. 8 is the same side view; FIG. 9- the same plan; FIG. 10-24 details.

The proposed machine is a combination of a hook-type block of block machines, and the basis of the hook-type machine with the necessary addition of a block store 7 of already known construction, with that difference,

that the movement of the block channel at the separation of blocks is not directed to the machine, but from the machine. On the main shaft 2, an eccentric B is added to rotate the block magazine 7, a gear 4, connected fixedly with an eccentric 5 to move the gear lever (not shown in the drawing), and an eccentric 6 is added to move the reversing tap.

Under the main shaft 2 there is a shaft 7 for moving the block 8 matrix 8 guide of the already known device. Shaft 7 has a disk 9 with a finger P, leading the rocker 10, as in a block box machine. This shaft is driven by the second gear / 7, which can freely rotate on the shaft 7 and is able to periodically rotate the shaft 7 with a finger, leading the finger 72 of the drive chuck 13 fixedly seated on the shaft 7. The device of this chuck 75 is quite similar to the already known drive to the cartridge of a hook or block machine. The guide S slides inside the matrix, 7 along its cylindrical holes 74 and 14 (Fig. 5). The hook guide 14 itself is driven from the main shaft 2 by means of a finger 77.

and the scenes 16 are similar to a block lock, with the finger 17 sitting in an eccentric 18 serving to move the lever 19 of the hook matrix 15. The lever 19 is curved to allow it to bypass the hook matrix guide (Fig. 3). The passage of the block matrix to the top is provided by a strut 20, dropping between the abutting clips 19 ° and 21 levers 19 and the levers 21 push hooks.

Simultaneously with the lifting of the strut 20, the lower ha 22 descends, withdrawing the brake rod 23 from the drive chuck 13 and allowing the driven pin 12 to meet with the driving finger // gear 11. The lifting of the strut occurs under the action. spring 24, t downward when turning the strut lever 25 to the right. In addition to this assignment, the strut 26 with its upper arm 20 still moves the toothed rack of the adjusting stop 26 by means of the toothed segment 2 with internal gearing and gear 28. This device is necessary to place the hooks somewhat further from the edge of the workpiece, as shown in FIG. 6

The movement of the strut arm 25 is controlled by the meter switching finger 56 inserted (threaded or otherwise) into one of the holes of the meter disk 57. When the meter disk moves, the switching finger 56 with its upper end enters the spiral groove 55 of the matrix switch fixedly connected to the roller 29 , leading the strut lever 25, and thus switches the machine to either blocks or hooks. The eccentric 6 of the counter during each revolution of the main shaft 2 moves the slide 32 by means of the lever 30 with the insert 31 (FIG. 3, 4), which in turn by a lead 33 moves the mechanism of the slide 34, consisting of the slide 35, moving the counter switch to the groove reverse, the roller 36, sitting on the finger of the slider 55 and entering into the arc groove 34 and two pushers 37 and 38 on the disk of the counter, pivotally connected to the slide 34. The pushers 37 and 38 of the disk 57 of the counter by means of springs 39 and 40 are pressed to the disk and their ends 57 and 55

can drop into the disk cavity 57, whereby the disk rotates one cavity with each turn of the shaft foot. At the same time, at the end of the disk movement, into one of the depressions of its creep, the latch 41 prevents the disk from civating when the catel moves backwards.

Each pusher has a tap; pin 57 and b0, which, raid-off 42, retracts the pusher to the CTC and thus ensures that the disc moves in one direction until the switch 43 (fig. 2) the counter will move the leash 55 backstage to the go side. Then worked that. Body 57 will be set aside. 38, and the pusher 38 in its turn will enter into operation. The count switch moves when the pedal is pressed with the foot when the machine is started up and is arranged according to the principle of belt translation at the grinding machines.

The machine is equipped with an automatic brake consisting of a slide 44 (Fig. 3, 4), which at one end enters groove 45 (Fig. 1) of the machine body, the other end 44 of which (having an oval groove 44 of Fig. 3) is mounted on the axis rotation 46 of the counter 57. The protrusion 44 of the slide serves to move it away with a roller 47 mounted on the adjustable pin 48 in the counter disk. When the roller 47 is pushed onto the outlet 44, the entire slide 44 will move to the center of the disc and release the brake rod 49 which will not slow down into the drive cartridge (not shown in the drawing) to stop the machine. The brake rod 49 bears a fixed attachment 5 (fig. 1, 3) of the lever 51, stop 52 of the block drive chuck 13. This stop 52 is intended for braking the lower

shaft 7 by means of a finger / 5 of the drive chuck 13 after the gear 11 stops, as the shaft 7 will continue to rotate by inertia and may prematurely pull the block matrix 8 up, which threatens to break parts. The disk counter 57 bears on itself two fingers 48 and 55, stocked; rollers 47 and 54 for retracting the brake slider 44, entering into

yooorodno As can be seen from FIG. 3, depicting the plan of the machine, the disk 57 moves counterclockwise, the finger 56 enters the slot of the switch matrix 55, while the last block is crushed (Fig. 1, 2). Through a complete rotation of the main shaft 2, not the blocks, but the hooks, will be crushed. They need to put four pieces and then move the brake slide. The machine will stop. New start-up of the machine will drive the counter in the opposite direction, clockwise; hooks are inserted at this time. After four turns of the main shaft 2, the finger 56 will again enter the groove of the switch matrix 55, and the machine will again begin to insert the blocks. Let them have to put five pieces. The position of the roller 54 will ensure that the machine stops just at the fifth block. New machine start and again in reverse order of five blocks and four hooks. A prerequisite for the operation of the machine is the same diameters of the tubes, both for the blocks and for the hooks, since the punches for cutting holes in the workpiece and for the bends of the tubes are the same throughout the work.

The machine should have a significant effect in the shoe industry, as it combines two close operations in one operation - inserting blocks and inserting hooks, which are still performed on two different machines. Since each of these machines requires no more than one second for its operation, and the preparatory movements of the worker, the machine causes it to be idle every time after stopping seconds for 5 or 10, combining these operations into one will undoubtedly increase the worker’s labor productivity due to destruction unnecessary simple.

FIG. 7-24, the proposed machine represents a further development of the described machine, consisting in using the same principle of periodicity of operation of the lower shaft 7 with the participation of the strut 20, with the only difference that in this machine hooks are placed in two blanks and followed by hooks there is an insertion of blocks too in both preparations. This is achieved through the use of double

the hook magazine 60 and the double block channel 7. The carrier of block matrices 8 has, instead of one matrix, two and a wedge 6J (Fig. 12), preventing an angular displacement in the carrier of hook matrices J4. The hook matrix carrier J4 has two hook matrix / 5 and 62 at the top (Fig. 9), respectively, with this lever 2 / the hook pusher has in addition the second (left) lever 63 rigidly connected to the lever 2 / via axis 64 (FIG. 7) . These levers receive movement from the eccentric 65 through the roller 66. The hook pushers are also two-right 67 and left 68. The left hook matrix 62 receives movement through the toothed sector 69 from the gear 70 of the right hook matrix 75, and the gear 70 moves from the gear lever 77, controlled eccentric 72, fixedly connected to the eccentric 73 of the conveyor belt, already known device. When lowering and lifting the hook matrix J4, the teeth of the gear 70 interact with the teeth of the lever 77, the teeth of which, as can be seen from the drawing, are wide enough to ensure constant engagement with the gear 70. FIG. 7, 8, and 9, the hook matrices 75 and 62 are shown in the ready position to pick up the hook from the hook slide 77 and 78 when pushed by the pusher 67 and 68. This will occur after the carrier of the hook matrices 14 has taken its lowest position and provided that the strut 20 will come off the pins 27 of the right lever of the pusher 2 / and / (pin of the gear lever 77 of the hook matrix), through which the strut 20 stops the movement of the gear hook 77 of the hook matrix 75 and 62 and the lever 27 of the hook pusher 67 and 68. The strut 20 has a protrusion 20, in which rests the roller 79 {f ig. 10) the lay-offs of the strut 80 rigidly connected to the axis of the lay-out of the strut 8J. On this axis 8 /, the matrix switch 82 is rigidly seated, receiving movement from the roller 83, the switching matrix and the ratchet sitting on the finger 57 (fig. 8, 9). This roller 83 causes the strut 20 to assume the position shown in FIG. 8, thanks to the spring 24, t the bottom of the gu 22 for the finger 22 downwards. In this position, the struts 20, the carrier J4 of the hook matrix, goes up and down and does not deliver a single hook for the punches 84. At this time, the carrier of the block matrix 8, which delivers the blocks for the punches 84, occurs.

The bridging cartridge 5 of the handwheel 86 has a roller 88 on its finger 87, which serves to activate the hooks 89. When the 4P brake rod comes around for the cartridge 85, the segment of the cartridge 90 (Fig. 7) slides on the finger 87 to the left and at the same time the roller 88 also moves to the left.

Due to this roller 5 (5 with further turning of the cartridge 85 until it stops, the protrusion 89 will meet (fig. 10a) and the hooks 89 will move and the strut 20 will be moved to such a position that both the lever 7 / and the levers 21 and 63 will have the opportunity to work. A ha 22 rises, and the brake rod 23 of the drive chuck 13 drops into the cartridge and turns off the movement of the lower shaft 7.

Simultaneously with the movement of the strut 20, its toothed end 20 moves, through the toothed sector P / and toothed lever 92, a sliding stop 93 hooks, which by its end PS prevents the hooks from moving out of the hook matrices at the moment of their stopping under the punches 84. By inertia, the hooks would seek to continue forward movement towards each other and would jump off of the lamellar curved spring springs 94 (Fig. 19, 21). FIG. 15-18 depict two different positions of the hook support 93 and the support of the blanks 95. FIG. 15-17 show the position at the time of insertion of the blocks, and FIG. 18 - at the time of insertion of hooks. During block insertion, the end 93 of the hook support is pushed back and the carrier of the block matrix 5 can move upwards; at the same time, the emphasis of the blanks 95 is rotated so that the blocks are somewhat closer to the edge of the blank; FIG. 18 shows the position of the stops P5 and 95 during the insertion of the hooks; hook stop P5 is located just between

punches and so as to hold the hooks on the hook matrices, warning them to jump off the latter. At the same time, the emphasis of the blanks 95 is rotated so that the hook tubes will be placed farther from the edge of the blanks than the tubes of the blocks.

During the insertion of hooks and right-hand blocks, the working hand attracts the right blank slightly to itself, and the left hand-left blank in such a way that the edge of the blank is in contact with the workpiece stop 95. Each workpiece is pressed periodically to the table J02 (FIG. 9) and to the matrix with a separate presser foot: walking to the right — pressed by the right presser foot 74, and walking to the left — by the left presser foot 75.

The presser legs are operated by an eccentric 76 fixedly connected to the eccentric 65.

In the machine, there is a counter 57, the ratchet of which moves in the course of operation in one direction, while twisting the spiral spring 97 shown in FIG. 9 dotted line. The offset of the toothed disk of the counter (ratchet) back under the action of the twisted spring 97 is prevented by the latch 99.

The lever 30 (FIGS. 3, 9), receiving movement from the eccentric 6, pushes the disk of the counter 57 with another latch 98. When the roller 100 on the disk 57 climbs the protrusion 44 of the brake slide 44, the entire slide 44 will move in the direction of the arrow and the brake rod 49 (fig. 7) will stop the car. At the same time, the pin 44 of the brake slide 44 pushes the end of the latch 98 and, overcoming the resistance of the spring 101, slides the end 98 of the latch from the ratchet teeth.

At the same time, the pin 44 will do the same with the latch 99. Then the gear disk released from the retaining latch 99 and 98 under the action of the twisted spring 97 will quickly turn to its original position. When you press the pedal with the new start-up the machine will again produce a countdown and automatic shutdown of the hooks and finally a new stop of the entire machine.

The subject matter of the invention.
