RU1815140C - Vibration hopper for orientated feeding of u-shaped workpieces - Google Patents

Abstract

Usage: automation of technological processes. SUMMARY OF THE INVENTION: the vibratory hopper has a bowl 1 with a supply screw tray 2 and a discharge tray 5, the axes and levels of which coincide. The feed tray 2 has a shoulder 3. which extends beyond the tray half the length of the part 4. The width of this tray is sufficient to allow movement of the part 4 along it, and the shape of the tray with the shoulder provides preliminary orientation of the parts. The protruding shoulder 3 provides an accurate orientation of the part 5 on the outlet tray 5. The profile of which is made in the form of a trapezoid for more stable fixation of the part 4. 5 il.

The invention relates to the automation of technological processes and is intended for orienting U-shaped parts with ends bent to each other, for example, clothespin springs.

The purpose of the invention is to increase reliability in orienting U-shaped parts with ends bent to each other.

On Fig, 1 shows a General view of the device; in FIG. 2 - the same. View from above; in FIG. 3 is a section AA in FIG. 2; in FIG. 4 is a section BB in FIG. 2; in FIG. 5 - detail of a U-shaped with ends bent to each other.

The orienting vibratory hopper comprises a bowl 1 with a feed screw tray 2, which is provided with a shoulder 3. The shoulder 3 is made protruding beyond the tray 2 by an amount L corresponding to N / 2 of the part 4.

A knife outlet tray 5 is attached to the tray 2. The axes of the tray 2 and the tray 5 coincide. The profile of the outlet tray is made in the form of a trapezoid, and the geometric dimensions of which correspond to:

the lower larger base corresponds to the smallest internal dimension of the part, i.e., yes;

the height corresponds to the height of the internal dimension of the part’s profile, that is, h “h;

the upper narrow base corresponds to half of the lower broad base, i.e., y - bll.

The device operates as follows.

Under the action of vibration, part 4 moves along the tray 2 of the bowl 1 of the vibratory hopper. The part may be located on the tray with the bent ends forward or the bent ends back. Parts located on the tray differently, as well as layered and interlocked parts, are removed back into the vibrating hopper bowl by ejectors of known designs (not shown). Parts that move forward with their curved ends are oriented along the tray 2 and, falling into the opening with narrow curved ends, take a vertical position, oriented to

output tray 5. The vertical position of the part is taken at the moment when the center of gravity of the part moves beyond the opening line. In this case, the somewhat elongated shoulder 3 of the tray 2 and the wall of the bowl of the vibratory hopper allow precise orientation of part 4 on the tray 5.

Parts 4 that move backwards at the moment of transition from tray 2

do not change their spatial position on tray 5, as they will be held along three planes: the horizontal plane of trays 2 and 5 (since the planes of the trays coincide), and on the sides - the vertical planes of the shoulder 3 and the inner wall of the bowl 1. That the moment when part 4, moving further under vibration, is no longer held by the horizontal plane of tray 2, but is still limited

these lateral surfaces, it will orient itself on the tray 5 and will also assume a vertical position on it. Oriented parts 4 on the output tray 5, made in the form of a trapezoid for more

the stable position of these parts in space, are discharged into the storage tank (not shown), and then along the technological cycle to the operating position.
