The invention relates to vehicles and can be used in rooms of various categories of fire and explosion hazards for transporting products and their accumulation in the implementation of various technological operations under conditions of conventional or flexible automated production.

The purpose of the invention is to improve the performance of the device.

Figure 1 shows the transport and technological device, a general view; figure 2 is the same, side view; on fig.Z - section aa in figure 1.

The device contains main overhead conveyors 1 and 2 with suspensions 3 and 4, placed between them The lock chamber 5 with the mechanism 6 for moving articles and tilting doors with doors 7 and 8, devices 9 and 10 for loading and unloading conveyors 1 and 2, accumulators 11- 14 with suspensions 15-18, lifting-swiveling mechanisms 19-22 with grippers 23-26 in the form of a horizontal fork, installed with the ability to move on brackets 27-30, and a system of driving reversing

34 and 35, and cylindrical dental couples 36 and 37. Lifting is carried out by supplying air under the piston 38. Lifting-swiveling mechanisms 19-22 are mounted with the ability to move along the housing 27-30, are rigidly connected to the lock chamber 5 on either side of the loading and unloading sites. The cantilevers 27-30 are a rigid structure consisting of a few corners, inside which rollers 39 and 40 move under the action of a pneumatic actuator 41.

The device has an automatic control system. For the normal organization of the transportation of products through the accumulation zones and places of overload, the ratio of the speeds of main conveyors, conveyor drives and the mechanism for moving the sluice chamber must be such that the cycle of products over time is a multiple of the pitch of the transported product.

The device works as follows.

In the course of the conveyor 1 are located

roller conveyors 31, connecting sluice Q processing, with each section

A new chamber 5 with a warehouse complex 32. The rooms of different categories of fire and explosion hazards are designated B and C (Fig. 1).

Drives 11-14 are vertically closed overhead conveyors and can be installed in free zones formed on both sides of the lock chamber 5. The lock chamber 5 with the movement mechanism 6 is a sealed hollow case with hinged doors 7 and 8, inside which placed the mechanism 6 moving articles in the form of a drive roller table and rollers located on the inner surfaces of the doors 7 and 8. The devices 9 and 10 for loading and unloading are zakva1n1 fork type, mounted nnye x on the door 7 and 8, in which grooves are made for the passage of gripping fork.

Lifting-turning mechanisms 19-22 are made of the same type (FIG. 3) and contain grippers 23-26 in the form of a horizontal fork connected to a turning mechanism and a lifting mechanism. The turning mechanism is driven by an electric motor 33 and consists of

corresponds to a certain type of suspensions (length, suspension pitch).

Some of the products concentrated on the warehouse complex from different sites of technological processing need to be transferred to the premises on the conveyor 1. In the absence of accumulators (warehouses) 11-14, the conveyor 1 would be idle waiting for the goods to arrive from the warehouse Complex Intermediate warehouses 11 -1 avoids disrupting the process mode.

From the warehouse complex 32 of the drive roller conveyors 31, the article was delivered to the lock chamber 5 and about the roller on the rollers and tilted that door 7. The gripper 24 is guided to the support of the door 7, lifted, picked up by the bus, rotates on 18 clockwise and, moving the console 28, enters the movement area of the intermediate warehouse 12, which is a vertical locking conveyor drive. A fig on the suspension 1b of the accumulator 12, when moving upwards, removes the product from the wadding 24, which then, having made

corresponds to a specific type of suspension (length, suspension pitch).

Some of the items concentrated on the warehouse complex from various processing sites need to be transferred to room B on conveyor 1. In the absence of accumulators (warehouses) 11-14, conveyor 1 would be idling while waiting for the goods from the warehouse complex. The presence of intermediate stores 11-1A allows you to avoid disrupting the process mode.

From the warehouse complex 32, the drive roller conveyors 31 delivered - the article to the lock chamber 5 and left it on the roller door of the tilted door 7. The claw 24 is guided in the direction of the console 28 under the roller support of the door 7, raised smiling, picks up out of the bus, rotates 180 clockwise and, moving along console 28, enters the movement area of intermediate storage 12, which is a vertically locking conveyor drive. The figurine suspension 1b of the accumulator 12, when moving upward, removes the product from the gripper 24, which then, making a reverse movement in the direction of the console 28, leaves: 1 movement of the accumulator 12. Thus, there is an accumulation of products in the intermediate warehouse 12. Further, these products can be promptly introduced into the process.

When filling the warehouse 12, it is possible to transfer the products to the intermediate warehouses 11 and 13 located in the room of category B. This happens as follows. The rolling table system 31 delivers the product to the roller support of the door 7 of the sluice chamber 5, in which the movement mechanism 6 transports the product to the roller support of the door 8. The gripper 25 closest to the accumulator 13 picks up the product from the roller support of the door 8 and, turning clockwise to I80 and moving on console 29, enters it into the movement area of accumulator 13, where it leaves (as in the previous case) to grip the product by suspension 17 of accumulator 13. After that, the fork 25 retracts through console 29 from movement area of accumulator 13. Similarly about there is a movement of products from the warehouse complex to drive 1 I,

In order to introduce the product into the technological process, it must be transferred from accumulator II (13) to conveyor 1. For this purpose, the gripper 23 (25) is placed in the zone of accumulator 11 (13) with the help of a tilt-and-turn mechanism (13), where from a given suspension 15 (17), the product is removed by forks 23 (25) during movement of the accumulator 11 (13) for transfer to the rollers of the tilted door 8, from where the product is overloaded by the device 9 to the suspension of the conveyor 1.

The device allows organizing cargo flows in various directions. Suppose some parts are required to be transferred from conveyor 1 to drive 13. The control system operates so that the grip 25 of the elevator mechanism 2I closest to drive 13, raised by the drive of the mechanism 21, removes the product from the suspension of conveyor 1, while the door 8 closed. Then, the gripper 25, by the action of the tilt-turn mechanism 21, rotates 180 clockwise and pushes the console 29 into the zone of movement 0

kopitel 13, whence the suspension 17, when moving up, picks up an article from the gripper 25, releasing it from the plug. The gripper 25 on the console 29 makes a reverse movement and leaves the zone of movement of the accumulator) 3.

By transferring products from accumulator 13 to accumulator II, gripper 25 is guided by console guide 29 into movement zone of accumulator I3 and forks of gripper 25, the product is removed from suspension 17 of accumulator 13. Then gripper 25 at console 29 moves out of movement zone of accumulator 13, turns 180 counterclockwise and stops in the overload zone. Door 8 is closed. A tilt-up mechanism 19 located on the other side of the sluice chamber 5, with a claw 23, removes the product from the claw 25 of the tilt-up mechanism 21 and, turning counterclockwise and then moving along the console 27, enters the zone of movement of the accumulator 1I, where the product is captured by suspension 15 of accumulator II, and the gripper 23 leaves the zone of movement of accumulator II, making a reverse movement along the console 27.

In order to transfer products from conveyor 1 to accumulator 12 or 14, the product stops opposite door 8 of the lock chamber 5. Door 8 opens, device 9 removes the product from suspension 3 of conveyor I and puts it on the roller supports of the tilted door 8 of camera 5, the movement mechanism 6 of which operates and delivers the product to the roller 7 of the door 7 in the room of another category of explosion and fire hazard, from where the product removes the grip 2A of the tilt and turn mechanism 20 closest to the accumulator 12, which rotates 180 clockwise and moves along the console Oli 28, introduces the product into the movement of accumulator 12, the suspension 16 of which removes the product from the gripper 24. Thereafter, the tilt-up mechanism 20 makes a reverse movement and removes the gripper 24 from the movement zone of the accumulator 12.

Similarly, the transfer of products to the accumulator 14 occurs with the difference that another lifting-turning mechanism is activated, located on the other side of the lock chamber.
