Description

The invention relates to mechanical engineering and can be used to load parts such as elastic rings, for example, to load rubber sealing rings in automatic assembly equipment.

The purpose of the invention is to increase the reliability of the device when loading elastic rings by eliminating the jamming of them in the output tray of the device.

FIG. 1 shows the device a general view from above; in fig. 2 is a section A-A in FIG. one; in fig. 3 — section BB in FIG. 2; in fig. 4 is a section B-B in FIG.

The device for loading parts of the ring type contains a vibrating hopper 1 with a screw feed chute 2 and an output chute 3 having a longitudinal rectangular groove 4 for loaded elastic rings 5, and a piece output mechanism. The longitudinal rectangular groove 4 of the output tray 3 is closed on top of the lid 6 and is made with a narrowed middle section 7. The width of the groove 4 in this section 7 is 0.95-0.97 from the minimum outer diameter of the elastic ring 5. - for 4 in its initial 8 and in the final 9 sections, it ensures the free movement of elastic rings along it and amounts to 1.015-1.03 of their maximum diameter. The piece-by-piece mechanism of elastic rings is a pusher mounted on the drive rod on the output tray 3 with the possibility of reciprocating movement along its axis. At the same time, its drive is made in the form of a power cylinder 10, and the pusher is in the form of a pawl 11 installed by means of a bracket 12 on the rod of the power cylinder 10 with the possibility of free rotation on the axis 13 relative to it in the direction towards the end part of the output tray 3. The mechanism of the piece delivery (in the direction to the end part of the output tray) can be ensured by the impact of the dog 11 on the elastic ring from the inside, its rotation in the opposite direction is limited by the wall 14 of the groove 15, made in the bracket 12. -

A device for loading parts such as rings works as follows.

Under the action of directional vibrations of the bowl of vibrating hopper 1 elastic. the rings 5 are transported bottom-up along its screw feed tray 2, enter the longitudinal rectangular groove 4 of the output tray 3 and move along its initial section 8 to its narrowed along the width of the middle section 7. As the width of the middle section 7 of the groove. 4 is smaller than the diameter of the ring, then before it the rings stop. The power cylinder 10 moves the dog 11 to its original position (in Fig. 1, the extreme right). In this case, with its mother-in-law part, it rests on the ring 5, which stands in front of the narrowed middle section 7 of the groove 4, and turns at some angle on the axis 13. Then, as it moves further to its original position, the dog 11 stops interacting with the ring 5, since appears inside the ring, and under the action of its own weight rotates in the opposite direction against the stop into the wall 14 of the bracket 12. When the power cylinder 10 is working, the dog 11 rests on the inside of the elastic ring 5 and, deforming it, pulls it through the narrowed the width of the section 7 of the groove 4. As the elastic ring 5 moves by the pawl, it leaves the / section 7 of the groove 4 and passes to its section 9, taking its original shape. At the end of the stroke under the action of its own weight elastic ring 5 falls from the dog 11 and then enters the process equipment. During the time of the first elastic ring, the vibrating tank 1 supplies the next ring to the narrowed section 7 of the groove 4 of its output chute 3, and then the cycle repeats.
