With 12 parts of shoes assembled on pads and reverse transfer from trolley 7 to table, 18 carriages 7 with empty pads 12).

The accumulator 5 is connected to a drive 21 for reciprocating it along guides (not shown) of a table with a perpendicular guide (not shown) of a press 6 for vulcanization, and the carriage 1 is connected with a drive 22 for moving it along a guide 19.

For operation in the technological mode pre, the automatic control system with which the sensors 23 are connected on the guide 19 for stopping the trolley 1 near the necessary technological equipment, the sensors 24 extreme positions of the moving parts 3 pairs of manipulators and the sensors 25 are installed and correctly installed carriages 7 on the drive 5.

The automatic control system includes a control unit 26 with controls - the drive 22 of the carriage 1, the drives of the presses 6, 13-15, the drives (not shown) of the manipulator 17 for removing shoes, the drive 21 of the drive 5, the drive (not shown) of the movable link 3 torus and table actuator 20 18. Sensors 27 are also connected to the automatic control system and the correct positioning of the carriages 7 in presses 6, 13-15, receiver 16, table 18, sensors 28 of the extreme positions of table 18 and accumulator 5, and sensors 29 for signaling about the full opening of the presses.

The device installed in the line for the manufacture of rubber shoes, works as follows.

Before switching on the device, the carriages with cathodes 12 are placed on the process equipment as follows: four pairs in the respective presses 6, 13-15j one pair on the receiver 16, two pairs on the table 18 and one pair on the accumulator 5, and the accumulator 5 has four guide slots a, in two of which, carriages 7 are located through one groove. The worker assembles two pairs of shoes on pads 12, located on table 8, at positions A and B. Cart 1 at this time is in front of table 18 at position B, that a pair of guides accumulate h 5 in There are no carriages 7 that are located coaxially with the guides of position B of the mill 18. After switching on the device and entering into the control unit 26 a signal from the sensors 25 about the presence of free space in the guide grooves of the accumulator 5, a command is received from the control unit 26 to turn on the drives of the moving links 3 pairs of manipulated tori. Moving links of manipulators are being advanced.

When extending, the grippers interact with the stops of the carriages 7, on which the pads with the collected shoes are located, as follows. Doggy 9, pulling on

the rack 10 rotates on the axis 8 until the link 3 touches the end of the rack 11 with its end. At this time, the pawl 9 sinks into 1 / -shaped sockets (Fig. 3-6), resulting in engagement of the grip with the carriage stop 7, on which there are pads with collected shoes. At the same time, the sensors 24 of the extreme positions of the moving links 3 are triggered, and the signal from these sensors gives the command to reverse the drives of a pair of manipulators. The movable links 3 slide in and move the carriages 7 with the shoes collected on the pads 12 from the table 18 to the hopper 5 (Fig. 7). The movement takes place until one of the sensors 24 is triggered. The signal from this sensor enters the control unit 26, from where a command is issued to turn off the drives of the moving links of the manipulators and turn on the drive 21 of the accumulator 5. The latter is displaced along the guides (not shown) of the table 2.

In this case, the dogs 9, moving, exit the K-shaped sockets (Fig. 3) and occupy a vertical position, as a result of which the grippers are released from the stops of the carriages 7, on which pads with collected shoes are located. The accumulator 5 is displaced until one of the sensors 28 of the extreme positions of the accumulator 5 operates. At this moment, the second pair of guide slots a and a carriage 7, which do not have assembled shoes, are aligned with the guides of the position B of the table 18. At the same time, at the moment of alignment of the guide tables and the accumulator, the grippers of the manipulators interact with the stops of the carriages 7, as a result of which the dog 9 is placed between the uprights 10 and 11, and the end of the movable link 3 abuts against the rack 11 (Fig. 8).

The signal from the sensors 28 sends a command from the control unit 26 to turn off the drive 21 of the accumulator 5 and turn on the drives of the movable links 3 of the manipulators, which are advanced, the ends of the movable elements abut against the racks 11 and the carriages 7 with the pads 12 on which there is no assembled footwear, move From accumulator 5 to table 18 (Fig. 9), at this moment sensors 24 are triggered, according to a signal from which control unit 26 issues a command to turn on the reverse of the drives of a pair of moving links 3 of manipulators that slide in. At the same time, the ss tank 9, bumping on the rack 10 and rotating on the axis 8, bends around it and occupies its original position (Fig. 10). The movement of the movable links continues until the sensors 24 are activated, the signal from which is sent to the control unit 26, issuing a command to turn off the drives of the moving links of the manipulators and turn on the drive 22 of the trolley 1. A cycle that involves moving a pair of carriages 7 from the process equipment to the accumulator 5 and the reverse movement of another pair of carriages 7 from accumulator 5 to technological equipment is called recharging and is carried out equally for all technological equipment, whether it is recharging table 18 or recharge receiver 16, or recharge npqlccoB 6, 13-15.

When the carriage is correctly installed, 7 with pads 12 on both pairs of guide tables 18 triggers sensors 27, the signal

0 from which the control unit 26 is received, from which the command is sent to turn on the drive 20 of the table 18. The latter moves until the sensor 28 triggers, the signal from which is sent to the control block 26, which gives the command to turn off the drive 20. The worker switches to another position A and collects on pads 12 new pair of shoes. After recharging the table 18, since the drive 22 of the trolley 1 is turned on, the latter moves along the direction 19, for example, to the press 13. On a signal from the sensor 23, the control unit 26 commands the drive 22 to turn off. The cart 1 stops near the press 13 so that the guide grooves and in which there are no carriages 7,

5 meters, signals from sensors 25 are received, would be coaxial with the press guides.

If the press 13 of the mold (not shown) is disclosed, then a signal from the sensor 29 to the control unit 26, which commands to recharge the press 13, during which a pair of carriages 7 with pads 12 moves from the latter to the drive 5 moves about it. without shoes, and in the press 13, a pair of carriages 7 with pads 12, on which shoe parts are assembled, moves from the accumulator. Then, on command from the control unit 26, the trolley I moves to the table 18 for recharging. At this time, if a pair of pads 12 with the details of the shoes are installed in the mold correctly, what about

signals from sensors 27 are received, the press molds of the press 13 are closed and the shoe vulcanization process takes place. At the same time, at position B of table 18, the latter is recharged, during which a pair of carriages 7 is moved from table 18

5 with the parts of the shoes assembled on the pads 12, and a pair of carriages with the pads 12 without shoes are moved onto it. Then the presses 6, 14 and 15 are loaded in the same way. By the time all four presses are loaded with carriages with shoes collected on the pads, the vulcanization process ends in the press that was loaded first, in this case in the press 13, and this press opens on a signal from time relay (not shown). By this point trolley 1

J again moves to press 13 with a new pair of carriages on which shoes are assembled. The press 13 is recharged again, during which a pair of carriages 7 with pads moves from the latter to the cart 1

12, on which the shoes are ready, and from the trolley 1, a pair of shoes 12 is moved to the press 13 with the assembled details of the shoes.

Following a command from the control unit 26, the trolley 1 moves to the receiver 16 and stops on a signal from the sensor 23. Then the receiver 16 is recharged, during which a pair of carriages 7 with pads 12 without shoes is moved to the trolley 1, and a pair of carriages with pads

which shoes are ready, moves to the receiver 16. If in the receiver 16 the pads with ready-made shoes are installed correctly, as indicated by the sensors 27, then the control unit 26 receives a command to the shoes of the shoe removal manipulator 17 and the finished shoes are removed from the shoes and stored her in tara. Next, the trolley moves to the table 18. Ana.total recharging of presses 6, 13-15 and removal of the finished shoe occurs.
