Description

In the proposed device for sorting sewing knives, with the aim of bringing the latter to one of the different profiles arranged on the disk, two double-arm levers are hinged on the pivotal disk, the long arms of which are intended for the designated purpose; the short shoulders of these levers serve to retract, under the influence of the eccentric, the coils in case of a mismatch of their profile with the pattern of the template, as well as to return the levers to their original position. Rotation of the disk with levers fixed to the templates on it is carried out with the help of a spike, which is under the influence of another disk under the influence of the spring-loaded latch, rigidly mounted on the rotating shaft.

In FIG. 1 shows a vertical section of the device; FIG. 2 view from above; FIG. 3 and 4 - details.

The proposed device (Figs. 1 and 2) consists of a rotating vertical shaft 1, on the ring 3 of which a disk 2 sits freely, capable of being rotated or at rest, independently of shaft 1.

On the disk 2 circumferentially located are two shoulders levers 4, rotating on hinges 5 and ending with spins (O & c)

There are 6 cases on which the sorting coils 7 are mounted, with the springs 8 acting on the levers, trying to turn them counterclockwise.

On the same shaft 1, an eccentric 9 rigidly sits, which, rotating with the shaft, with its projections 10, acts on the short arms of the levers 4 and deflects them at a certain angle clockwise, thus causing the spring 8 to stretch.

Concentric with the disk 2 is the disk 11, on which the templates 32 are fixed, for testing the coils 6 mounted on the spindles 6.

On the shaft 1, another disk 12 is also rigidly mounted (it can also be combined with disk 9), which are periodically turning the disk 2 at some angle, for which there is a device consisting of a spring-loaded, rotating on the axis 13, latch 14 (Fig. 1 , 2, 3, and 4), which by force of the spring presses against the spike 15, firmly seated on the lower surface of the disk 2, and thus, as the disk 12 rotates, the disk 2 will rotate with it.

To stop the disc 2 and hold it in its position, there are two dogs 16 and 17 sitting on the fixed frame of the device, and the dog 16 stops the disk 2 when one of the protrusions of the latter, when it is rotated counterclockwise, is pressed into the dog 16, and the other dog 17 at the same time, it will push another similar protrusion from the opposite side and prevent the disk 2 from rotating clockwise.

At known moments, a double-shouldered lever 19 acts on the dog 16, the lower arm of which presses the finger 20, which sits on the disk 12, the dog 16 moving away from the protrusion 18, and the disk 2 comes into rotation again.

On the shaft 1, there is still a loose disk 22 connected to the uprights 21, and an eccentric 23 acts on the disc 22, causing the disc together with the uprights to periodically raise or lower.

Shaft 1 receives rotation from motor pulley 24 by means of pulley 25, screw 26 and worm gear 27, which is rigidly mounted on shaft 1. At the same time, eccentric 23 receives rotation from shaft 1 by means of gears 28, 29 and 30.

The device works as follows. The shaft 1 is rotated at a certain speed counterclockwise by the transmission 25, 26 and 27, and the disk 9 and the disk 12 also rotate together with the shaft 1; as soon as the latch 14 resists in pinch 15, disk 2 also begins to rotate, until the latter protrudes 18 into protrusion 16, and then disk 2 immediately stops, and dog 17 immediately rests on another protrusion 18 and will not allow disk 2 to rotate back clockwise; thus, the disk 2 is precisely fixed in place. The disks 9 and 12 together with the shaft 1 at this time rotate at the same counterclockwise speed, and the protrusion 10 leaves the short arm of the lever 4, as a result of which the other end of the lever with the spindle 6 will describe the arc near the center 5 spindle coil 7, in case of compliance with the template profile, will pass through template 32 (Fig. 1, dashed line) and on the other side will be dropped from the spindle by striking the bottom flange and coils of racks 21, which at this moment receive a push up from the eccentric 23.

In the case of a mismatch between the profile template and the coil profile, the latter does not pass through the balance (the templates are arranged in increasing sizes), but stops near it, and when the protrusion 10 approaches the short arm of lever 4 and turns it clockwise, coil 7 moves away from the pattern and take its original position.

After that, the finger 20 presses on the lever 19, and this latter, in turn, on the dog 16, which, as a result, moves away from the protrusion 18 and releases the disk 2, immediately carried away by the disk 12, and the disk 2 again stops at the exact spot , lever 4 will describe the arc again, and coil 7 will try to go through a new pattern, etc.

In this way, each oia spindle coil bypasses all templates and, in the case of a mismatch of the profile of all the templates with the coil profile, the latter is still reset before the first (initial) template, after which a new coil is put on its place, going for a test, etc.
