Description

The invention aims to mechanize manual labor for charging nails on the heel shoe in a Lightning machine and thereby increase the productivity of the machine.

In FIG. Figure 1 is a side view of the proposed fixture; FIG. 2 is a longitudinal section of FIG. one; FIG. 2a, 26, 3-5 parts of the device.

The proposed device consists of a shield 7 with located on it two drums 2, having a swinging movement, obtained through the gear 3 from the reciprocating mechanism. Inside the drums of the common axis 4, fixed inclined grooves 5 are placed. To the ends of the grooves, tubes with channels 6 are inserted into the drums. Thus, when the drums 2 are rocking, the nails inside them are scraped by the blades 7 and dropped onto the grooves 5, along which rolls one by one, they fall into channels 7 and fill them to the very end. The ends of the channels 6 have slots 8 in front (Fig. 2a) and are enclosed in cups 9, also having JO slots. Below the cups 9 is placed another row of cups 77 (Fig. 1), the inner diameter of which is equal to the diameter of the channels b. Against these cups, on a common roller J2, are planted and rigidly connected to the latter.

levers 75 (fig. 4), the upper ends 75a of which, equipped with shock absorbers J4 with two springs 75 fixed at one end on the fingers 76 and the other on shield 7, constantly strive to be inside the channels 6, pressing against the walls of the latter in nails and thus delaying their further advancement down. Simultaneously with pressing the upper ends J3a of the levers 75 nails to the walls of the channels b, the lower spatulate ends 756 of the levers move away from the cups 77, freeing the output of the nails from the latter. From the cups 77, the nails are guided into the funnels of the tubes 77, where (if the cone-shaped nails are charged) they pass through the first bend, using transverse triangular prisms 7, level and fall further down. After that, getting into the second, bending of the tubes 77 and hitting the 7P shock absorbers, the nails again turn over on the projections 20 and fall down with a sharp end. Thus, the nails on the section A of the tubes 77 go constantly with the head down and on section B, hitting the projections 20, turn over and fall in the desired position, i.e., point down. Upon being placed in this position, the nails are guided to the rigidly mounted tubes 27 on the yoke 22, through which they fill the heel shutter 23, then, after the last handle 24, turning 180 ° around the stand 25 becomes above the nozzle array. / Automatically opening the shutter 26 with the shutter 23 allows the nail to go into the holes of the die. At the moment of turning the shutter of this device to the nozzle machine, the protrusion 27 finds on the tip 38 of the heel shutter 23 located on the end of the lever 28 attached to the shield 7, and deflects it as shown in FIG. 4. At this moment, the upper spherical end of the lever 28 finds on the cam 29 rigidly seated on the common roller 12 with the levers 13, deflects it to the side and thus the lower ends 136 of the levers close the lower openings of the cups // and release the clamped upper ends / 5a, nails at the ends of the channels 6. Nails, pads down, remain in the cups // until the heel curtain 23 rises under the yoke 22, after which the lever 28 comes off the protrusion 27 and under the action of the spring 30 clears the cam 29 will be set to the original position. At this moment, the levers / 5, freeing the nails from the cups 11, are clamped at the same time by the nails 6 coming through the channels 6 in the cups 9 (Fig. 26).

The proposed device is designed for two sizes of heel, of which the larger heel has twelve nails, and the smaller one - ten. For this purpose, the holder 22 has two rows of holes corresponding to the shape of the heel, s which fix the ends of the tubes 21 (Fig. 3). As shown in the drawing (Fig. 1), using the lever 31, the lower ends of the tubes / 7 are retracted and installed over one or another row of tubes 21, for which the lower ends 39 of the tubes 17 are connected by a common bar 32, the pins of which are enclosed in guides brackets 33. The upper part of the tubes 17 is also connected by a common bar 5 moving in bearings 55. To switch the tubes 17 to charge the nails of the sleeve 12 under a smaller heel that requires ten nails, a spring-loaded lever 36 located on the bar 32, having at the top end two engines 37 which having closed the upper openings of the cups // (fig. 5), turn off the two extreme tubes 17 out of a total of twelve. Since, when filling the heel block with nails to one or another heel size, the position of the center of the latter does not change, from the row of tubes 17, the outermost tube 17a is fixed and directed directly to the sleeve 22 (Fig. 1).

The subject matter of the invention.

Claims (3)
