Abstract

The invention relates to the field of engineering. The aim of the invention is to simplify the design and increase the reliability of the device in operation. The transport device of the automatic line contains a closed chain conveyor with a stepping drive, devices - satellites and an orienting mechanism. The orienting mechanism of the device contains gigs placed on the sides of the conveyor and equipped with a reciprocating drive. Spring-loaded dogs are mounted on the rods, interacting with the rollers of the conveyor chain carrying satellites for selecting gaps and precise positioning of satellite devices relative to the process equipment.

The invention relates to mechanical engineering and can be used in transport devices of automatic lines with chain conveyors.

The aim of the invention is to simplify the design and increase the reliability of the device.

For this purpose, in the transport device of the automatic line, containing a closed chain conveyor with stepper movement, satellites and an orienting mechanism, the latter contains spring-loaded pawns mounted on reciprocatingly moving in the direction of chain movement and interacting with the rollers of the conveyor chain, and the hinge connections of the conveyor links are made with a gap in the direction of its movement.

FIG. 1 schematically shows the proposed device, obts; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows an embodiment of the clearance of a swivel chain.

On the frame 1 of the transport device, a vertically closed chain conveyor 2 is mounted, comprising a drive 3 with a control system (not shown), two drive sprockets 4 located on both sides of the conveyor, two driven sprockets 5, a working belt of the conveyor with driving and driven branches 6 and 7, guides 8 and 9. On the plates 10 of the conveyor 2, the satellites are articulated .11.

The hinge connections of the conveyor 2 are made with a gap (Fig. 2) between the fingers 12 and the plates 10. The total size of the gaps of the links between the two positions of the automatic line is greater than the greatest possible deviation of the position of the satellite 1 1 device from its nominal position in the working position .

Wired paws 13 of the orienting mechanism 14, mounted on the fingers 15, mounted on both sides of the conveyor and receiving reciprocating movement from the drive, 16 mechanism interact with the fingers 12.

In the area of the leading sprockets 4, a sensor 17 of the control system is installed, monitoring the change of satellites 1 1 in the working position.

Along the conveyor 2 on the axis 18-22 placed technological equipment (not proven) automatic line.

In the initial position, the thrusts 5, occupy the extreme right (according to the drawing) position, and the dogs 13 are to the right of the respective axes 18-22 of the process equipment.

The automated line transport device works in the following way.

On command from the control system, the drive 3 is turned on and rotates the drive sprockets 4, moving the working canvas of the trans 5

of the porter 2 by a predetermined amount before the signal from the corresponding satellite 11 arrives at the sensor 17. At the same time, the remaining satellites 11 are positioned to the left of the nominal position, taking into account the position error. The position error increases in the direction of the driven sprockets 5.

Simultaneously with the movement of the conveyor 2, the drive of the orienting mechanism 14 moves to the left (retracts) the rods 15. At the same time, the pawl 13 freely passes by the fingers 12 of the chain, compressing its springs. At the end of the stroke, the pawl 13 takes a position known to the left of the actual position of the fingers of the 12 chain links carrying the respective satellites 11.

After processing both movements, a signal is sent from the control system of the device to the movement of the pulses r 15 to the right. In this case, the dogs 13 meet in their path the corresponding fingers 12 and, dragging them to the right, select gaps in the pivotally connected chain links. As a rule, the leftmost satellite, which has the largest position error, and the others behind it, begins to move first. The conveyor chain 2 is pulled up (assembled).

At the end of the turn, the pawl 13 occupies a nominal position. Since they are a hard stop for the links of the conveyor 2 carrying satellites 11, the last

They occupy a nominal (calculated) position corresponding to the location of the process equipment.

Dogs 13 of the orienting mechanism 14. Can be installed not only on the OB1, they are for each side of the conveyor

5 tons gah; but also on separate ones. These ropes can have both common and separate drives. Moreover, the deviation from the synchronism of the individual drives does not affect the positioning accuracy of the satellites.

A prerequisite for the operability of the device is the presence of a freely hanging trailing branch, which allows the transport web to be moved by the drive of the orienting mechanism when the iiOM conveyor is turned off.
