Description

The invention relates to a machine tool industry and can be used in the automation of serial and small-scale production.

The purpose of the invention is to increase the reliability of the conveyor in operation by ensuring accurate stopping of the transport carriage at the processing position.

FIG. 1 shows the layout of an automated line using a conveyor; in fig. 2 is a view A of FIG. one; in fig. 3 - section bb in Fig.2; in fig. 4 - section bb In figure 2; in fig. 5 - section GGD in FIG.

The conveyor on the automatic line contains the base 1, on which the track 2 is rolled, the transport trolley 3 installed with the ability to move along the track 2 by means of a thrust chain 4 On the transport trolley 3 a shaft 5 is mounted with an asterisk 6, bend around the thrust chain 4, the mechanism for stopping the transport carriage 3, made in the form of a disk 7 mounted on one shaft 5 with an asterisk b with a diametrical groove 8. A liner 9 is installed inside the diametrical groove 8 with the possibility of moving along it; The rotation of the sprocket 6 is made in the form of a latch 10, installed with the ability to interact with grooves I 1 made on the disk 7.

Along the conveyor there are machines 1 2 s -SHU, controlled centrally from a computer (not shown) and overload device 13. Based on 1 conveyor in the area of the overload device of the monitors, stops 14 for precise stopping of the transport carriages 3.

The conveyor for the automatic line operates as follows.

The computer commands on machines 12 installed along the conveyor process the parts. The supply of blanks to the machines 12 and the removal of the machined parts from them are carried out by the transport carriage 3. In accordance with the program of work laid down in the computer, the machine 12 is determined, on which the part is overloaded from the transport carriage 3 (to the machine 12 or vice versa).

In front of the device 13, the overload of the machine 12 extends the stop 14 and to

This position by means of the traction chain 4 moves the transport carriage 3. When the transport carriage 3 is moved, the locking device O is located in one of the slots 11 of the disk 7 and prevents the shaft 5 from turning.

At the approach of the transport carriage 3 to the stop 14, the latter enters the diametrical groove 8 of the disk 7. The diameter of the pedestal 14 is equal to the width of the diametrical groove B of the disk 7. The abutment 14 rests against the insert 9 located in the diametral groove 8 of the disk 7, and with further movement of the transport carriage 3, the insert 9 moves along the diametral groove 8 and stops. The stop 14 prevents further movement of the carriage 3. The subsequent movement of the traction circuit 4 through the sprocket 6 causes the disc 7 to unlock and rotate the shaft 5 with the disc 7 by 90 °, after which the traction circuit 4 is electrically stopped, for example, by contactless command sensor (not shown).

Thus, the diametral groove 8 of the disc 7 is turned perpendicular to the direction of movement of the transport carriage 3, and the stop 14 fixes the latter exactly in front of the overload device 13. After stopping the transport trolley 3 at the command of the computer by means of the device 13 overload.

machinable parts and loading machine 12 workpiece.

Upon receiving the command for the subsequent movement of the transport carriage 3, the movement of the traction chain 4 begins. In this case, the transport carriage 3 remains fixed by the stop 14, and the movement of the traction chain 4 causes the shaft 5 with the disk 7 to rotate until the lock 10 enters the groove P of the disk 7, the diametral groove B of the disk 7 is located parallel to the movement of the transport carriage 3, and the stop 4 does not prevent the movement of the transport carriage 3. After that, the joint movement of the transport carriage 3 by means of the traction chain 4 begins. The stop 1 4 extends from the diametral groove B of the disk 7 and is retracted to its original position.

At subsequent positions, the cycle is repeated.
