Description

BACKGROUND OF THE INVENTION 1. Field of the Invention .

The hitherto known devices for controlling brick machines are designed on the basis of sliding circular registers or fixed memory circuits for individual movements. As shifting registers are used programming devices - with a cam belt, a programming card, or a combination of programming discs, or electronic shifting registers. The stepping of these devices is pulsed directly from the end positions of the individual movements of the machine part. Fixed memory circuits consist of memory relays controlled from the previous movement, from the end positions of the previous and subsequent movement. Of these, the memory relays have a small number of starts.

One of the machines in the ceramic production is the machine for storing desserts. The automat can be divided into two manipulators, the first manipulator creating the desired shape of the individual layers of the landfill lining, the second manipulator creating the desired shape of the landfill.

The above-mentioned drawbacks are eliminated by a device for controlling automatic machines in ceramic production, which consists of cyclic working manipulators for creating layers and dumps consisting of a programmable logic pole composed of two matrices, in the first matrix logical product and in the second matrix logical sum and bistable In accordance with the invention, the sensors of the high-tech process position are connected to the third, fourth, fifth and sixth inputs of the first matrix of the programmable logic pole, and to the seventh input of the same matrix there is a toggle switch. Eight and ninth inputs of the first programmable logic pole matrix are connected to inputs defining a landfill and layer creation program. The outputs of the first programmable logic pole matrix are connected to the inputs of the second programmable logic pole matrix. The first output of the second programmable logic pole nut is connected to the first flip-flop input, and the second output of the second programmable logic pole matrix is connected to the second flip-flop input. First output from. the flip-flop is connected to the second input of the first programmable logic pole matrix and the second output of the flip-flop ¹ is connected to the first input of the first programmable logic pole matrix. The third, fourth and fifth outputs of the second programmable logic pole matrix are inputs for the actuators of the controlled process.

Advantages of the device for control of automatic machines in ceramic production are that instead of several logic elements a programmable logic field is used, whose connection allows, if necessary, to conceal the real connection. An advantage of the apparatus for controlling automatic machines in the ceramic production according to the invention is that the only adjustable flip-flop enables the automatic operation of the manipulator to be started at any place even after the power supply failure. The ceramic manufacturing machine may have two, three or more manipulators accordingly, and the ceramic manufacturing machine control apparatus has two, three or more bistable flip-flops.

An example of a particular embodiment is shown schematically in the attached drawing.

The drawing shows a block diagram of a device for controlling automatic machines in a ceramic production. The process input position sensors are connected to the third input 4, the fourth input 5, the fifth input 6 and the sixth input 7 of the first matrix 2 of the programmable logic pole 1, and the flip-flop 11 is connected to the seventh input 8 of the same matrix 2. On the eighths 9 and ninth 10 of the input of the first matrix 2 of the programmable logic pole 1, outputs are connected to degrade the formation of the stack and the layer. The outputs of the first matrix 2 of the programmable logic pole 1 are connected to the inputs of the second matrix 3 of the programmable logic pole 1 are connected to the first input 12 of the bistable flip-flop 11; The first output 14 of the flip-flop 11 is connected to the second input of the first matrix 2 of the programmable logic pole 1 and the second output 15 of the flip-flop 11 is connected to the first input of the first matrix 2 of the programmable logic pole 1. The third output 16, fourth output 17 and fifth the output 18 from the second matrix 3 of the programmable logic pole 1 are inputs for the actuators of the controlled technological process. The individual connections in the first matrix 2 and the second matrix 3 of the programmable logic pole 1 are made after designing the control algorithm of the respective automat. The required programmable logic array 1 is used according to the number of sensors and actuators of the controlled technological process.
