Abstract

The invention relates to the automation of technological processes and can be used for the automatic feeding of technological machines with piece blanks, mainly caps, in which the ratio of height to diameter is close to one. The purpose of the invention is to increase productivity. Parts 12 of the type of cylindrical caps are loaded into the plate 3 and along the conical bottom 5 they slide to its periphery. On the way of movement along the bead, the parts meet stencil holes 4, through which those of them that stand on the ends fall through. Failed parts, not changing their position, fall on the conical bottom of the 2 bowl 1 vibrobunker. The distance between the conical bottom of the plate and the conical bottom of the bowl is 1.05-1.2 the height of the part, and the angles of their forming equal. The parts that have fallen to the bottom of the bowl continue to move in the same direction, and through the window 7 in the shell exit to the feed tray 6 located on its outer surface. Upon further movement, the parts approach the orientator 8 and incorrectly oriented ones are dropped back into the plate 3. 2 Il.

Description

The invention relates to the automation of technological processes and can find application for automatic. supply of technological machines with piece blanks, mainly caps, in which the ratio of height to diameter is close to unity.

The aim of the invention is to increase productivity due to the accelerated process of orientation of the parts.

In Fig. 1, a vibratory hopper is shown, a general view; in FIG. 2 - the same, partial longitudinal section.

The vibro-hopper contains a cylindrical bowl 1 with a conical bottom 2 and a plate 3 having screen holes 4 at the periphery of its conical bottom -5. The screw feed tray 6 is on the way of its movement along the side of the plate, the parts are met, the screen holes 4, through which j only those ones which in the plate stood at the ends fall through. The failed parts become on the bottom of the bowl 1 also on the end and can no longer change their position, since 1Q as the distance between the bottom of the plate and the bottom of the bowl is 1.05-1.20 the height of the part, the screen holes in the bottom of the plate form several parallel orientation channels and Only 15 can be distinguished from three possible initial positions of the part (at the end, on the side along the bowl, on the side across the bowl). - at the end, the parts that have fallen to the bottom of the bowl are laid on the outer surface of the shell of the bowl 1, in which a window 7 is made for the parts to exit onto the feed tray. In the upper part of the tray 6 there is an orientator 8 in the form of a cutout with a tongue and a chipper 9 in the form of an inclined 25 plate fixed to the shell of the bowl 1. Plate 3 is connected to the bowl 1 with a screw 10 _o In the gap between the bottom of the plate 3 and the bottom 2 of the bowl there is a plate 11 located at an angle to 39 the direction of movement of the parts.

I

The distance between the bottom of the plate and the bottom of the bowl is 1.05-1.20 the height of the oriented part. The diameter of the screen holes 4 exceeds the diameter of the oriented. Details on the magnitude of the amplitude of the horizontal vibrations of the edge of the plate. The angles of inclination of the bottom of the plate and the bottom of the bowl are equal.

The vibration bin operates as follows.

The parts 12 to be oriented and fed, for example, cylindrical caps with Ι / d 1 1, are loaded in bulk into the tray 3. Under vibration, they slide along the inclined surface of the bottom of the tray to the periphery towards the board. Oscillations of the plate cause the movement of parts in the direction indicated by the arrow.

must move in the same direction, slide to the shell of the bowl 1, along the path of their movement are captured by the plate 11 and sent to the feed tray · 6. Due to the fact that there would be a lot of parts between the plate and the bowl, they go into the feed tray in a continuous stream. Having reached the orientator 8 in its movement, the caps located upside down overturn on the tongue and, with the help of a chipper 9, go back to the plate. The caps moving upside down pass the orientator along the feeding tray.

Claims (1)

Claim A vibratory hopper containing a cylindrical bowl with a conical bottom and a window in the shell for passage of parts to the feed tray located on the outer surface of the shell, characterized in that, in order to increase productivity, it is equipped with a cone with a conical bottom and a number of screen holes on the periphery, installed with a gap above the conical bottom of the bowl, and the angles of inclination of the bottom of the plate and the bottom of the bowl are equal.
