The invention relates to the technical properties of information systems and can be used to account for blanks of rolling mills transported in methodological heating furnaces and along a conveyor.

A device for recording moving products is known, comprising a sensor for the presence of a product, signal formers, elements AND, a unit for determining the direction of movement, and a counter G1 J

The drawbacks of the device are low accuracy of accounting, since the presence of a transport line for random reasons of the product when entering or leaving the product leads to taking into account a product with false information about its parameters, and insufficient functionality of the device, since its functions are limited by products

on such a transport line, on which only one product can be simultaneously. The organization of metering on the conveyor requires the use of two devices, the sensor for the presence of the product of one of which is installed at the input of the transport line, and the sensor of the other device at the output of this line, and their counters are combined into a common metering unit controlled by signals from the outputs related elements and integrated devices.

The closest to the invention to the technical essence is a device for recording the movable products containing the first and second position sensors of the product, the outputs of which are connected respectively to the first and second inputs of the control unit, the sensor of the product parameters, the memory block, the detection unit

addresses, write and read unit, reversible counter and display unit.

This device works as follows.

In the initial state, in the absence of products on the transport line, the counters of the address determination unit are set to zero, and by the time the first (starter) product arrives on the transport line, there are no other products on this line, which is a condition for the accuracy of the trigger product.

The arrival (input) of the starter on the transport line triggers the first sensor of the presence of products whose signals. the state is changed by one unit of the first counter of the address determination unit. Parameter information is written to the memory block from the sensors for this product. As the next product arrives on the transport line, information about them is rewritten into cells of the memory block with addresses increasing by one in accordance with the state of the first counter. When the first and subsequent products exit the transport line, a second product availability sensor is triggered. With this, with the output of each product, the state of the second counter of the address determination unit increases by one. Information is transmitted from the memory unit to the executive unit at the address determined by the state of the second counter on the corresponding item 2 J.

The disadvantages of the known device are the low rate of registration of products during the transition from the non-stationary (start-up) mode of the accounting of products to the stationary mode of accounting of the product and the limited scope of application of the device. The non-stationary mode of metering occurs, for example, due to the repair of the equipment of the transport line, preventive maintenance (shutdown) of the device and sudden failure of the equipment of the device.

These reasons cause the device to turn on again (start up) the device for recording products in a situation in which the main condition for the realization of the device is not fulfilled - the absence of products on the transport line by the time the starter enters it. Consequently, the device’s equipment can be turned on again after the transport line is cleared from the products, as a result of which using this device reduces the metering rate of the products when switching from non-stationary to stationary metering, which consequently reduces the performance of the transport line.

The limitation of the field of application of the device is explained by the impossibility of its implementation in relation to multi-zone heating furnaces, the operation of which excludes the possibility of complete removal of metal from the furnace.

The aim of the invention is to improve the speed and the expansion of the field of application of the device.

The goal is achieved by the fact that a device for recording movable products containing the first and second product position sensors, whose outputs are connected respectively to the first and second inputs of the control unit, the product parameter sensor and the memory unit, has an actuator motion monitoring unit, the output of which connected to the third input of the control unit; the output of the first position sensor of the product is connected to the first input of the control unit for the movement of the actuating mechanisms; the second input of the actuator motion control unit and with the fourth input of the control unit, the outputs of which are connected to the inputs of the memory unit, except the last one, to which the output of the product parameters sensor is connected.

In addition, the actuator motion monitoring unit contains displacement sensors, triggers, AND elements, OR element, counters and comparison element, the outputs of the first displacement sensor are connected to the first inputs of the first AND element and the first trigger, the output of which is connected to the second input of the first and the input of the second element And the outputs of which through the element SHS connected to the counting input of the first counter inputs. the actuator motion monitoring unit are the inputs of the second trigger, whose output is connected to the second inputs of the first trigger and the second element Inc.

FIG. 1 shows a block diagram of a device; FIG. 2 is a functional diagram of an actuator motion control unit} in FIG. 3 - the same, the execution of the control unit; in fig. 4 shows the positional diagrams; the following shows the movement of products (billets) along the transport line of the continuous heating furnace with walking beams of the rolling mill. The device contains the first 1 and second 2 position sensors of the product, the control unit 3 for the movement of the actuators, the control unit 4, the sensor 5 for the product parameters, the unit 6 for memory and the executive unit 7. The unit 3 contains the first 8, second 9, and third 10 motion sensors , the first 11 and second 12 elements are And, the second 13 and the first 14 triggers, the element OR 15, the first 16 and the second 17 counters, and the element 18 of the comparison. The control unit 4 comprises an element 19, a first 20 and a second 21 counters, a switch 22, a first 23, a second 24 and a third 25 pulse shapers. FIG. 4, pusher 26, starting billet 27, loading roller conveyor 28, walking beam 29, furnace loading zone 30, furnace unloading zone 31, receiving roller conveyor 32, mechanism 33 for discharging billets from the furnace are indicated. lag 34 of mechanism 33, workpiece 35 in the displacement area, distance L. 36 between sensor 1 and front border 37 of zone 31, coordinate x 38 of the front end of the workpiece, coordinate Y 39 lag 34. As is known, furnace loading, moving the workpieces in the furnace with walking, beams and unloading of the furnace is carried out through transport mechanisms (Fig. 4). The pusher 26 serves the billet to the furnace loading zone 30 at a predetermined interval relative to the previous billet (in our example, hatching is used to depict the starting billet 27). The striding beams 29 transport a successive series of blanks in the furnace, in order to supply the blank to be removed from the furnace, to a predetermined position in the zone 31 of the furnace unloading. The mechanism 33 for removing the stoppers from the furnace removes the blank from the discharge zone 31 of the furnace and places it on the receiving roller 32, and in the discharge zone 31 and in the charge zone 30 there can be several blanks at the same time. Block 3 functions as follows. in a way. When the Start button is pressed and a signal is output at the output of sensor 1 (Fig. 2), which reflects the entry of the starting billet into the furnace (at the time of crossing, for example, the front end of the billet of the line of sight of sensor 1), the trigger 13 changes to a state of one. On the leading edge of the signal, trigger 13, counter 16 is reset, which is determined by the code corresponding to the length, i.e. the distance between the sensor 1 and the front border 37 of zone 31, and, in the case of butt-landing, the source code of counter 16 is set taking into account the temperature lengthening of the kiln casing (a series of blanks in the furnace). The trigger 14 enters the unit state by opening the element 11 and, as a result, the path pulses that occur at the first output of the sensor 8. As the starting blank moves towards the zone 30, they begin to flow to the counting input of the counter 16 operating in the subtraction mode. When the direction of movement of the pusher 26 changes according to the signal arising at the second output of the pusher movement sensor 8, the trigger 14 returns to the initial state, whereby the And 12 element through the first and third inputs is opened with units of the flip-flops 13 and 14, resulting in the counter input 16 track pulses are received from the first output of the sensor 9 for displacing the beams when the walking beams 29 are moved, and in the counter 16 the code corresponding to the X coordinate of the front end of the starting blank relative to the positions 37 is fixed. A counter 17 operating in the “jiggle” mode receives traveling pulses from the second output of the sensor 10 of the mechanism 33 for issuing the CUTS from the furnace when moving the lag 34 of the mechanism 33 in zone 31 towards the furnace and in the counter 17 is fixed to the corresponding Y coordinate of the mechanism 33 relative to the position 3 In this case, the number-pulse code at the input of counter 17 is converted in this counter, for example, into a binary code, which in element 18 is compared respectively with the binary code of counter 16. When the values of the codes are the same, element 18 generates a signal Which re alizuets control unit 4. The appearance of the comparison signal means that the lags of the mechanism 33 are located under the required starting billet, by means of which 3) take the billet from the furnace and place it on the receiving roller table 32. The control block 4 (Fig. 3) is intended to control the operation modes of the block 6 memory The control unit 4 operates in the following manner. When the Start button is pressed, the counters 20 and 21 are reset to the initial (zero) state. When the workpiece is supplied to the loading zone 30 by the sensor 1, a signal is generated, which is fed to the input of the imaging unit 23, to the input of the switch 22 and the counting input of the counter 20 as a result. shaper 23 generates a pulse control signal Record in the time interval determined by the duration of sensor signal 1. Switch 22 switches to transmitting the counter status code 20 to address inputs A ... A of memory block 6, at the address defined by the counter status code 20, the block 6 records the information about the parameters of the workpiece entering the load zone 30, the counter 20 on the falling edge of the signal of the sensor 1, translates to the next state, which determines the new address of the pair information bang another zag & aration to be put into a furnace. When the workpiece is out of the discharge zone 31, the sensor 2 generates a signal which, through the element 19, in the presence of the permission signal from the output of the block 3, enters the input of the former 24 to the input of the switch 22 and the counter input of the counter 21, as a result of which the former 24 generates a pulse control signal Read in the time interval determined by the duration of the signal of sensor 2. Switch 22 switches to transmitting the status code of counter 21 to address inputs A..iA of memory block 6, at the address defined by the roto counter code 21, in block 6 of memory and reading is performed (reading) information on parameters of the preform from the furnace vschannoy. The counter 21 on the trailing edge of the signal of the sensor 2 is transferred to the next state, which determines the new address for reading information about the parameters of the next billet to be output from the furnace. The device in relation to the method of passing the heating furnace operates as follows. When you press the Start button and the signal appears at the sensor 1 output (Fig. 1), which shows the start-up and subsequent billets entering the furnace loading zone 30, the device implements the following Recording mode functions: measuring the X coordinate of the start-up workpiece moving in section L using unit 3 relative to position 37 of the exit of products from the furnace and the formation of a block 3 of the enabling signal at, where V is the coordinate of the rods of the mechanism 33 for issuing blanks from the furnace; sampling the cell of the memory block 6 with the address determined by the state of the counter 20 of the block 4 by the control1, as it enters the zone 30 of the launch and the subsequent blanks, the information about their parameters is copied from the sensor 5 into the cells with increasing by one

The address is in accordance with the state of the counter 20.

With the appearance of the permissive signal of the unit at the output of block 3 and signals

sensor 2, displaying the start-up of the pusher as compared with the known second and subsequent billets, the kiln unloading performance and the quality of the finished product will increase the following functions of the read mode, as well as reduce downtime

sampling of the memory cell 6 from the ad-equipment of the rolling stands

Resome, determined by the state of the account-.

Start accounting start and subsequent blanks.

The main technical and economic advantage of the proposed device is the control unit 21; as the billets from the furnace (starting with the starting billet), information about their parameters is read from the cells, whose addresses increase by one in accordance with the state of the counter 21, when billets from the furnace are delivered to the starting billet. , the signals of sensor 2 are not identified by element AND 19 due to the absence of an enable signal from unit 3 at its input and, therefore, these blanks are not taken into account by the device and should not be taken into account, since for some reason the Start button was missing correct information about their parameters; transmitting information about the parameters of the starting and subsequent blanks taken from the furnace to the executive unit 7. In addition, the appearance of the enabling signal at the output of the unit 3 is used to indicate the fact that the starting blank has left the zone 31, i.e.
