Description

I

The invention relates to automatically m transport devices and can be applied in the radio engineering, engineering and other sectors of the industry for transporting predominantly fragile cargo between work positions, as well as for mixing in the latter.

Automatic transport installations are known for transferring goods from one workplace to another, containing a trolley with a driven main roller and a driving roller having a rolling surface that differs from the main one, an additional roller, which are mutually compatible with the main running track and additional rail segments, located above the worker. And | MI places. However, the speed of movement of freight trucks in such installations is limited. In addition, at high speed, the accuracy of stopping the trolley is not required.

The aim of the invention is to ensure operation both in automatic and manual control modes, and to expand the field of use of the installation.

For this, the main and additional rollers are rigidly fixed on the drive shaft, and the additional rail sections are set movably relative to the ocHOBior de rail and are equipped with actuators, alternately bringing them into contact with the additional roller.

To simplify the track design

and increasing the compactness of the installation, each additional rail segment is installed parallel to the main rail and has a transition section with a smooth change in its width and height and a straight working section, and the additional drive roller having a cylindrical rolling surface, which interacts with the straight working section, is made with lateral conical rolling surfaces interacting with the working edges of the transition section.

In addition, the drive of each rail segment can be made in the form of electromagnets, connected by means of levers to wedges that interact with bevels.

movably mounted strips on which the rail segment is rigidly fixed.

FIG. 1 shows schematically the proposed installation, the general view; in fig. 2 is a section along A-A in FIG. 1 (main and auxiliary drive rollers in the traveling position at working speed); in fig. 3- installation in (position of movement on the tra) speed sport speed; in fig. 4 - transition section of an additional rail segment in the plan; in fig. 5 - rollers at the time of the two transition zones.

The automatic transnortal installation contains a cargo trolley / on which a drive support 2 with a gearbox 3 is mounted, on the output shaft 4 of which the main 5 and full 6 rollers, equipped with a rolling side surface of the rolling roller, forming a trapezondal groove . The main roller 5 engages with the Osgüv M rail 8, which is one of the two-rail rails of the cableway. On the road over workplaces monolithic leg segments are monitored

9, which interact with an additional roller 6 for a given program. Rail segment 9 is rigidly fixed on the bar

10, which has bevels P interacting with the movable members. 12. The bar 10 is fixedly attached to the pivot arms 13. The wedge 12 is connected with the electromagnets by means of the levers 14. The springs 16 are designed to return the wedges 12 to the original polishing. The rail segments 9 are supplied with a transition section 17 with a smooth change in its width n (HEIGHTS.

The trolley / is equipped with idle supports 18, the rollers of which interact with the running rails 8 of the cableway. A telescopic load-lifting organ 19 is rigidly attached to the trolley / with a lifting mechanism 20 and an ax-shaped crank driven by an electric motor 21. A lifting body 22 is rigidly fixed to the last step of the telescopic load-bearing organ 19.

From the initial position (for example, near the multi light pulsed conveyor 2.9), when the electrical circuit is turned on, the drive rollers 5 and 5 get rotated and the carriage moves in direction of the floor conveyors 2 with the transport speed, as the main drive roller 5 interacts with the rail 8. Transport speed of movement Telephones significantly increase the speed of movement of known vehicles. Simultaneously with the motor included in the motor, in accordance with the program, the electromagnets 15 are activated above the required workplace. Electromagnets 15, by means of levers 14, move wedge 12, which, when interacting with bevels 11 strips 10, lift the latter together with the rail segment 9 by the amount necessary to create a garanty gap between the main drive roller 5 and the rail 8 when the additional roller 6 hits the rail segment 9 .

 carts at transporting speed occurs until the additional roller 6 interacts with the transitional vifcT 17 of the rail section 9. The lateral conical surfaces 7 of the roller 6 roll around the working edges of the transition section 17. At the same time, the distance from the axis of rotation of the roller 6 to the lines of contact of the lateral surfaces rolling with non-transitional working edges / 7 (rolling radius) decreases smoothly.

Proportional to the radius of the roll, the speed and movement of the carriage smoothly decreases. In | K10Nce of the transition section 17, the roller 6 passes over the cylindrical rolling surface, and the carriage is not emitted at a working speed, which is 2-3 times less than the transport. Receiving a command from the nut limit switch, the front drive motor shuts down and the electromagnetic brake is activated at the same time. Due to the low working speed of the movement, an exact stop at the right place is guaranteed. After the trolley stops in accordance with the program, the electric motor 21 of the mechanism 20 of raising and lowering the telescopic load-lifting organ 19 turns on, which, when pulled out, starts the load gripping body 22. After lowering the latter to the required level, a command is issued from the limit switch located on the load-lifting organ 19, to turn off the motor 21 and reverse turn on the motor of movement. The trolley at working speed moves in direction to the load, and the lifting body 22 turns out to be a node. The motor 21 of the lifting and lowering mechanism is then turned on, and the load gripping body 22 removes the load from the conveyor 24, lifts it to a height of two meters to provide a passage between the conveyors and, gradually increasing the speed of movement (when the roller 6 moves but in a non-transitory direction 17k in the opposite direction ) to the transport, the trolley goes to my side of the ruspo.

A rail section 9 with a transition section 17 is also installed above the multi-conveyor belt, the interaction with which m of the additional driving roller 6 floating reduces the non-movement speed to the working one, and the trolley stops. Zatom.m on the program. Triggered telescopic lifting body 19, which lowers or raises the load, depending on the load floor. After the load is in front of the required floor, the trolley at the working speed enters the load between the legs of a large blond conveyor and stops. The load-lifting organ 19 with the gripper 22 is lowered. Above this, the load remains on the paws of a fresh, light-weight conveyor, and the bottom surface of the gripper 22 does not reach the load located on the floor below. The cart then leaves the working speed of the multi-bay conveyor 23 and stops at a position where roller 6 does not reach the transition section 17. Grip 22 is set to the transport position (level 2 m above the floor), the drive motor turns on, and the cart smoothly increasing the speed to the transport, is directed to the next floor conveyor. The cycle is repeated. Thus, the design of the installation provides two speeds of the front truck P - transport and working, with a smooth transition from one to another. Stops and moving from the place, as well as moving to workplaces are carried out at working speed, and transportation of cargo at a significantly higher transport speed. This results in an increase in plant performance. This prevents damage to fragile goods, and also ensures good stability of the truck and the accuracy of its stopping at work places. The subject of the invention is an automatic transport installation for transferring goods from one workplace to another, comprising a trolley with a driven main roller and drives: having a different rolling surface than the main speed, an additional roller that interacts respectively with the UN motorway rail of the track and additional rail segments located above workplaces, characterized in that, in order to ensure the operation of both automatic and manual control modes, The primary and secondary rollers are rigidly fixed to the drive shaft, and the additional rail segments are movably mounted relative to the main rail and equipped with leads that alternately bring them into contact with the additional roller. 2. Installation under item 1, characterized in that, in order to increase its compactness and simplify the design of the track, each additional rail segment is installed parallel to the main rail and has a transition section with a smooth change in its width and height and a straight working section, and the additional drive roller is made with lateral conical rolling surfaces interacting with the working edges of the transition section. 3. The installation, characterized in that the drive of each rail segment is made in the form of electromagnets connected by means of levers to wedges interacting with bevels of a movably mounted strip on which the rail segment is rigidly fixed.
