Abstract

Usage: days of supply of core blanks to processing machines and industrial robots. SUMMARY OF THE INVENTION: on the wall 5 of the hopper 1, which has a gate for dispensing workpieces, a movable, spring-loaded strap 8 is installed relative to the wall with a lower edge tapered towards the hopper and with stops to interact with the gate above which the strap is located. When the gate is raised, the excess workpieces that are on its knife 4, the meeting the lower edge of the plate 8 .. are dumped back into the hopper 1, and the remaining through the gap between the knife 4 of the gate and the lower face 9 of the plate 8, fixed stops, from the knife 4 of the gate on the output threshold 13 roll into the receiving: tray 15. 1 zp 5 l,

Description

 J.;:

The invention relates to mechanical engineering and can be used to feed rod-shaped workpieces to metalworking machines and to the grip position of industrial robots.

The purpose of the invention is to increase the reliability of the device.

A bar movable relative to the wall of the hopper, having adjustable stops interacting with the gate and beveling towards the hopper, removes excess workpieces located directly on the gate from the gate and provides the necessary clearance between the wall edge and the bar for the passage of the workpiece, which prevents jamming of the workpieces during delivery them to the output tray.

In FIG. 1 shows a device in cross section, the gate in the lower position; in FIG. 2 - the same, the gate in the upper position; in FIG. 3 is a left view of FIG. 1; in FIG. 4 is a left view of FIG. 2; in FIG. 5 - adjustable emphasis, cut.

The device contains a hopper. 1, in guides 2 of which, with the possibility of reciprocating movement, a slide 3 is installed with a knife 4 and a drive (not shown in the drawing). The upper edge of the knife 4 is inclined to the wall 5 of the hopper. Two guides 6 are fixed on the wall 5, in which rods 7 are arranged with the possibility of axial movement. The opposite ends of the rods are pressed into the strip 8 above the slide with the bevel 9 towards the hopper. Between the guides 6 and the bar 8, there are compression springs 10 worn on the rods -7. On the right and left ends of the bar 8, adjustable stops are installed in the form of threaded rods 11 screwed into the bar with heels 12 having contact with the upper edge of the gate. An output threshold 13 is attached to the upper edge of the wall 5 with the upper plane tilted outward 14. At the outer edge of the threshold 13, a receiving tray-drive 15 is installed. There are blanks in the hopper

sixteen. ,

Before operation, turning the rods 11, the adjustable stops are adjusted so that when the upper edge of the gate 3 contacts with the heights 12, the gap between the knife 4 and the bar 8 is larger than one cross section, and

less than the cross section of the two workpieces.

To feed parts from the hopper 1, i include a gate drive 3, which, when moving along the guides 2 from the lower position with a knife 4, captures the workpieces 16 located in the hopper, oriented along the wall 5. The blanks can be located on the upper edge of the knife 4 along

a height of more than one row. With further rise, the gate approaches the strip 8 located at the lower position and at rest relative to the wall 5, the blanks of the upper rows alternately meet the beveled surface 9 of the strip and are dumped back into the hopper. Only the bottom row blanks remain on the knife. When the gap between the upper edge of the knife 4 I and the bevel 9 reaches a predetermined one, the gate 3 will come in contact with the heels 12 and through the rods 11 will move the bar 8, compressing the springs 10 and moving the rods 7 in the guides 6. The specified gap at subsequent movement.

will remain constant. When the upper edge of the knife 4 is aligned with the plane 14 of the threshold 13, the remaining workpieces are rolled along them to the receiving tray 15. The gate starts to lower, and after it reaches its initial position, the cycle repeats. :. :
