 , On

The mastery is related to automatic control devices, in particular to systems of software control by a group of objects, and can be used in the field of integrated automation of production processes, yap {(measures, during the development of automatic vibration control equipment on a personal assembly line on an assembly line, where assembly vehicle modifications, when the technical problems of finding an aggregate for their modification and delivery to the assembly area, must be solved synchronously with movement, the co-driver, with a certain distance between the units in the set.

A device for managing a group of objects is known that contains identical control channels for the number of objects which increase in proportion to the total volume of the system, while the functionality of the system remains limited to l.

The closest solution to this invention is a device for programmatically managing a group of objects containing, by the number of objects, control actuator blocks, a "matching match block connected via local memory blocks to a code converter, and sequentially connecting the central memory block and the decoder, connected to address selection blocks 2.

The indicated device, which provides for the selection and control of static objects, has the above-mentioned disadvantages. In addition, the device does not synchronize the cycle with the stages of the process.

The aim of the invention is to expand the functionality of the device.

In order to achieve the specified circuit, the serially connected shaper of signal signals, the counter, the second block of coincidence are entered into the device

and the distributor connected to the code converter n to the control units of the actuators, one of the inputs connected to the outputs of the corresponding local memory block, the outputs of the pre-phase code step connected to the inputs of the counter n of the second matching block, the outputs of address selection connected to the inputs of the corresponding local memory blocks and the first block of the match, B1 1xBd5k & t6rog6 connection 1yun with the input of the central memory block, and the output of one of the blocks of actuators by actuators is connected to one from vhddov local memory bpokov. .j..Also, in order to increase the speed of the device, a program selection block is connected to the address selection block in it.

The drawing shows the block diagram of the device.

The description of the device and its operation is given on the example of the construction of a set of two dissimilar objects.

The scheme contains a central memory block 1, a decoder 2, blocks 3 and 4 for selecting the address by the number of objects (in the case of the first and second objects), block 5 of the program, the first block coincides with 6, local blocks of memory 7 and 8 by the number objects, code converter 9, search block 1O of the address of the technological position to which an object should be held containing the driver

11 clocks Shvlpilkov, counter 12, the second block of the match 13, valve 14, control blocks 15 and 16 of the HCV control mechanisms {nairikler, gates) according to the number of objects. Each 9K 3 and 4 contains a trigger signal forma lvatep 17, a counter 18, an object type code converter 19, and a match 2O element.

C (& a neutral memory block 1 and a decoder 2 for the purpose of setting up the Tffiie information, and To determine the types of a given set of objects. Blocks 3 to 4 choices

each object is intended to examine the lines (the outboard overhead warehouse to compare the code of the Inverted & m object with the object code, for $ 1x at the examination of the “second line of the warehouse.” Conversion 9, distributor 14 and blocks 1O, 15 and 16 are intended to control the outflow of objects from a warehouse in a selected sequence with &

a given distance between the objects in the set and their delivery to the assembly site synchronously with the movement. conveyor belt

The device works as follows.

In the initial state, the signal at the input of block 1 is absent, and the block itself is free for recording 1 hectare (| jurmament coming from the code definition). There are no signals to the dashi (|) attor 2, and, consequently, oTcyTCTByidY.output signals. With a co-op code, the set code is received — on unit 2, written in it, then it goes to the remote controller 2, and on esro output is pre-phased into object codes, made up this set. With decoder 2, the object codes are sent to identical blocks for selecting the address of each object, namely in block 3 of the first The object and in block 4 of the second object, -..

Consider the work unit 3.

Two types of signals arrive at the inputs of this block: the code of the first object requested for a given set, which supplies a match 26 to one of the inputs, and a request signal indicating only the presence of a call, regardless of the composition of its code. With the arrival of the request signal to the entrance of the spacer 17 at its output, a sequence of rectangular pulses is received, which is transmitted to the counting input of the decimal counter 18. The pulses are recalculated, and at the output of the counter 18c, with a frequency of their succession, the signals corresponding to cfrsh 1 2,, ... "9.0 which, in turn, correspond to survey numbers of the warehouse lines mx. In the converter 19 Operation, preofasion of the number of the examined warehouse line into the code of the object located on the subject line. The object code signal from the output of the converter 19 post is input to the element of coincidence 2O, where it is compared with the code of the object being requested, coming from descriptor 2. If these codes do not match, counter 18 continues to periodically change its output state. survey warehouse lines. When the same codes at the output of the element from the junction 2O, a signal appears, indicating the choice of the warehouse line with the required type of object. This signal, acting on the driver 17, stops pulsing the input of the counter 18. Similarly, the selection of the warehouse line with the required second object is performed. The signals from blocks 3 and 4 are fed to the inputs of block 6, in turn, the signal in turn, which means that the requested set is selected for the call in question. This signal enters blocks 7 and 8 for each object, carried out AND () MEURS of lines, and their output is “1X stopped from such a block 3 and 4. In the absence of the requested object in the warehouse, no line number will be recorded . The examination continues until the driver 17 runs a pulse sequence and lasts, for example, 7 seconds. If during this time iv fflra is not found, a signal for stopping the conveyor is generated. After the next 7 seconds, noBojSoe survey will be performed, and so on until a line is found. Simultaneously with the recording of the requested objects in blocks 7 and 8, the output signal from block 6 of the match 6 erases information from the central storage unit 1. The survey process was considered above, provided that the warehouse lines are equivalent and each of them is viewed properly. Sometimes, for organizational reasons, it is necessary in a short period of time to release a certain warehouse line in order to use it for objects of another type. In this case, a preference is given to this line, i.e., during the examination, the viewing starts from the window, which is ensured by the program selection block 5, which affects the operation of the counter 18. The addresses of the request are sent to the inputs of the converter 9 and on. the inputs of blocks 15 and 16, producing the release signal objects. npeo6jpet3e atel 9 converts the number of liters (in the warehouse to the number of the cam in the free-wheeling conveyor;, the private of the warehouse line under consideration, that is, converts the object's address code into the address code of the required technological position, which then goes to the counter and 12 input of the second block of coincidence 13 of block 10. At the same time from converter 9, a signal is sent to distributor 14. In accordance with the action of signals from converter 9, counter 12 starts counting the clock of these pulses from driver 11, driving Mogo into action by pushing the cups The output conveyor to the limit switch (the burner. The output signal of CHEERCH 12 is fed to the input of block 13, with equal signals at the inputs of which, i.e. if the numbers of the given and current numbers coincide) of the cams, a signal is sent to its b-output 14, which is intended for switching signals on the permissive inputs of the power units 15 and 16 in a given order, taking into account the ition on the output conveyor. When both signals arrive at the inputs of the distributor 14, it will issue a triggering pulse / release of the first object to the block 15. Further, the signal from the output of the distributor 14 in the converter “e” is affected and the task is changed — a signal is given to the INPUT of the matching block 13, which specifies the cam number of the second object. The circuit functions as described above, and the required object is directed with the corresponding warehouse lines. The command for outputting the second object oofSOf eMenno is also a command for resetting requests in memory blocks 7 and 8. After the second object leaves the warehouse, all blocks of the device are reset. When using this device in a vehicle assembly process, a large number of auxiliary equipment and servicing units are released on the assembly tracker due to the conveyor delivery of the units, a precise rhythm of operation, operation and high speed of the conveyor. The device provides a fully automated set-up (Shtomobil, excluding mistakes due to staff servicing. - ;;,.: The claims of the invention 1.
