SU408885A1 - DEVICE FOR DETERMINING THE DIRECTION OF THE MOVEMENT OF A REVERSIBLE ELEVATOR WAREHOUSE - Google Patents

Description

one

The invention relates to the field of control of closed reverse elevator warehouses, conveyors, etc., and is intended to select the shortest path and relocate any warehouse cell to the loading point and automatically start the drive in the vertical direction.

The known devices for determining the direction of motion are based on subtracting from the end of the reference the origin of the reference and the subsequent P1, by analyzing the result obtained.

In the proposed device, the principle of “compaction, is that; Two counters are used in parallel, one of which, a bell counter, has a number of states n equal to the number of cells in a warehouse or conveyor, and the other counts the number of states and the number of cells in a warehouse / (/ 2.

With a peleus-speed increase, blocks of setting the beginning and end of the countdown, a ring counter, a block of coincidence, and start blocks "Forward and Back" are entered into the device. At the same time, the task reference block of the motion reference is connected 1K to one of the similarities of the ring counter, the output of which is connected to the end of reference job block and to the "B | before." The other input of the ring counter is connected to one of the outputs of the clock pulse generator, and the other

g, the output of the generator-to the meter connected to the launcher “Yazad.

In the drawing, a functional device is shown.

It contains a block for setting start 1 and end 2 for reference, ring counter 1, block 4 fall, start blocks "Forward 5" Back 6, counter 7, generator 8 clocks of 1 pulses.

The stoppage of the warehouse in any position with the help of the unit 1 set the reference point in the ring counter 3, the current address of the salary, located at the receiving window. In the task of the reference frame, the address of the warehouse cell is generated, which the operator wants to call to the reception window. The end-of-frame boundary is entered into the ring counter via a bore.

The bottom of the movement of the warehouse will be shortest if the number of cells being scanned and n in the chosen direction is less than / 7.2. But therefore, before each start-up, it is automatically checked that it corresponds to the parallel operation of the counters 5 to 7 in forward direction, i.e., upwards} 1 and addresses from O to / g / 2. If the number of enumerated addresses from O to n / 2 in direct direction is less than or equal to n / 2, then to re-start of counter 7 there is a triggered-npe coincidence circuit, which is issued in the diagrams:

Start Forward Block Start Scheme Back Up and Flush Counter 7. When the number of enumerated addresses is greater than "/ 2, when the count is equal to l / 24-1, counter 7 overflows. The overflow signal of this counter starts the Back Circuit Start Block. match.

The subject is invented and

A device for determining and directing the movement of the reversing elevator warehouse, containing a clock pulse generator and counter, characterized in that, in order to increase the speed of the device, it includes blocks for setting the start and ponet count, ring counter, match block and start blocks Forward and “Back, with

The motion reference unit is connected to one of the inputs of the ring calculator, the output is completely connected through the coincidence unit to the end of reference setting unit and to the Forward starting unit, the other input of the ring counter is connected to one of the outputs of the generator pulses, another output which is connected to the counter connected to the “Back.
