Description

The invention relates to a machine tool industry, in particular to the construction of automatic lines, which address parts and operate in fire-hazardous premises.

The aim of the invention is to increase productivity by providing automatic addressing of parts.

FIG. 1 shows the scheme of the described automatic control line, general view; in fig. 2 - stepping conveyor (forward stroke); in fig. 3 - conveyor bar; in fig. 4 - stepping conveyor (forward stroke and stroke of the position cylinder); in fig. 5 - the same, the rod stroke back; in fig. 6 — pusher-turner pusher (position for moving a suitable part); in fig. 7 is the same position of reject movement.

The automatic control line for case parts contains step-by-step conveyors 1 and 2, located between them a turning-edging table 3 with a collider 4, a loading crane 5 suitable parts, a loading crane 6 defective parts installed in the reception area conveyor-conveyors 7–9 defects (at least least one) and work posts 10-12. Each of the step conveyors 1 and 2 consists of a frame (not shown) and a composite rod 13 installed in it (FIG. 3). The rod 13 is connected with a reciprocating drive in the form of a cylinder 14 and consists of sections 15-17, which at the locations of work posts are interconnected by means of positional cylinders 18 and 19 of a stepping reciprocating movement with a double-sided rod. Markers 20 are mounted on the rods 13 at the locations of the work posts 10-12.

On each section 15-17 and on each cylinder 18 and 19 along the entire length of the rod 13

are swinging and transmitting swinging cams 21 with a pitch I equal to the stroke of the piston of the cylinder 14. In addition, sections 16 and 17 of the rod 13 (i.e., each

sections located after the first from the side of the supply of parts of the working post, in our case, post 10) and on the cylinder 19 (i.e., on each of the positional cylinders, starting with the cylinder located on

The second working post, in this case, at the post 11) before each cam 21 in the direction of the forward stroke of the rod 13, additional cams 22-24 are installed. Each of the cams 22-24 is shifted relative to the cams 21 with step c. 12 and ta1, corresponding to the specific steps of the additional position cylinders. The number N of additional cams 22-24 located in front of

each of the cams 21, corresponds to the number of reject addressing positions (the number of conveyor drives 7–9 of rejects in FIG. 3 N 3), i.e. each of the cams 21-24 in the group is for transmitting the part

at the appropriate address: cams 21 - on the material handler suitable parts 5, cams

22- to the first position of marriage address- conveyor-accumulator 7 defects, cams

23- to the second position of addressing the reject-conveyor-accumulator 8 rejects, cams

24- to the third position of marriage address- conveyor-accumulator 9 defects.

The pivoting / rotating table 3 is intended to rotate parts at an angle of 90 °, and the mounted on it the pusher 4 is equipped with a swing cam 25 and additional cams 26-28. Each of the cams 26-28 is shifted relative to the cam 25 with pitch p, 12, and ts1, respectively. At the beginning of the conveyor 1, a pneumatic distributor 29 is installed, which is connected with the rod of the main cylinder 14.

Automatic line works as follows.

Parts that are subject to control on the automated line are fed to the guides of the stepping conveyor 1. In this case, the piston of the cylinder 14 is in the extreme left position (Fig. 2). When a part arrives on the conveyor 1, it commands the cylinder 14, for example, by means of a pneumatic distributor 29 with mechanical control to move the cylinder rod 14 to the right. The cam 21 of section 15 slips under the part, and then during the course of the rod 13 to the left it captures the part and moves it along the conveyor 1. The next cycle repeats after the part has appeared at the position of the pneumatic distributor 29.

When a part arrives at work post 10, the controller inspects or the automatic post controls its quality according to the process. If the part is fit, the cycle continues in the same sequence and the part is transported along the conveyor 1 by the cams 21.

When a part arrives at the rotary table 3, the suitable part collides with the cam 25 (Fig. 6) on the conveyor 2 and is further transported over it by the cams 21, and then with the scrap loader 6 is transferred to the loader 5 of the suitable parts and transported further along the technological process.

If a defect is found at a working post, for example 10, with which the part must be sent to the first accumulation rejection position (reject accumulator 7), the position cylinder 18c is moved by the cam 21 (Fig. 4) to steps followed by the return cylinder 18 the initial position after the return stroke of the rod 13. During the return stroke of the rod 13 (Fig. 5), the cams 21 and 22 slides under the part. Further transportation of the part is carried out by the cams 22 with a transport step equal to the course of the rod 13. If the part arrives la the next working position with an offset relative to the marker 20, its control is not performed. When a part arrives at the rotary table 3, it collides with the cam 26 (Fig. 7) on the conveyor 2 and is further transported over it by the cams 22, and then with the scrap loading crane 6 is transferred to the conveyor-accumulator 7.

If a defect is found at work station 10, with which the part must be addressed to conveyor drives 8 and 9 of rejects, -.

moving the position cylinder 18 with the cam 21 to the pitch of the step T2P and ta, respectively, followed by the return of the cylinder 18 to the initial position. Transportation to the conveyor drive 8 is carried out

Cams 23, and pushing the I-conveyor 2 by cams 27, and on conveyor-drive 9 - cams 24 and 28.

If a defect is detected at work stations 11 or 12, then the corresponding position cylinder is also moved and the cam 21 moves the given step depending on the defect, and further movement is carried out by the corresponding additional

cam on conveyor drives marriage.
