Abstract

The invention can be used to automate the processes of loading parts of automatic machines and automatic lines. The purpose of the invention is to provide automatic feeding of parts from a cassette. The cassette includes a housing 1 with guide bars 2 forming grooves 3 for parts, and samples 4 with dimensions along the width of the groove for accommodating the bearing surface of the part are made in the lower part of one of the guide bars of each groove. 10 il.

Description

FIG. 2

The invention relates to mechanical engineering and can be used in the automation of loading processes with parts of automata and automatic lines.

The purpose of the invention is to provide automatic part feeding.

Figure 1 shows the cassette, a general view; figure 2 is a section a - a in figure 1; on fig.Z - cassette, top view; figure 4 - section B - B in figure 2; figure 5 is a sample; figure 6 - cassette installed on the equipment; figure 7 - section b - In figure 5; on Fig - detail of the sample; Fig. 9 shows a cassette loaded with T-shaped parts; 10 shows a cassette loaded with L-shaped parts.

The cassette consists of body 1, guide bars 2, forming grooves 3 for parts. In the lower part of one of the guiding strips 2 of each groove, samples 4 were made along the groove width. The sample is made with dimensions of width greater than the width of the end of the part 5

d c, where d is the groove width;

c is the width of the face of the part, the height of the smaller height of the end

where h is the height of the sample;

H - the height of the end of the part, the depth is less than the difference of the length of the diagonal from the lower angle of the end of the part adjacent to the bar to the upper corner of the end of the part adjacent to the opposite bar and the width of the groove between the bars

t (b - a), where t is the depth of the sample;

b - diagonal details;

and - the width of the groove.

The equipment includes a setting plate for mounting and moving the cassette case 1. Guide

has a slant 7 for straightening the bottom row of parts. In the guide there is a safety device 9 for receiving the parts from the cassette.

The cassette works as follows. The cassette is loaded by hand.

or on the machine. The parts are inserted into the grooves 3 formed by the guide bars 2. The lower part 5 of each slot is inserted when the lower end angle is lowered into the sample. made at the bottom of the bar, buckling and wedging. When inserting the following parts, the bottom part becomes even larger from the weight of the upstream ones. The cassette with the lower part 5 of the body is installed in the guide 6 and moves until the first slot coincides with the safety gear 8. The lower part, when moved from the impact of the bevel 7, straightens and becomes parallel to the 0 plane of the guide, the end angle comes out of sample 4. Then the part is under the action of the weights of the upstream parts are forcedly dropped into the safety device 8. After unloading one row of box office parts, 5 is fed a step. This cycle is repeated until all parts are unloaded.

The cassette design allows you to automate the process of preparing and feeding parts from the cassette by eliminating manual 0 operations to prepare the cassette for operation, as well as to cassette parts of more complex shape, such as T-shaped, L-shaped.
