SU913423A1 - Device for monitoring position of rolled article - Google Patents

Description

The invention relates to the automation of rolling production and is intended to track the movement of rolled products and determine its location.

five

The known device for recording objects moved by the conveyor, containing sensors, allows you to determine the location of the rolled products in areas obzhgmnyh, varietal and harvesting mills. Tracking the movement of products around the mill is carried out using sensors installed along the production line [1).

Since tracking is carried out on the batch movement (in fact, on the last item in the batch), when one item is removed from the batch, the device gives false information, since the boundaries of the batch are shifted and the batch data and each rental are distorted.

The closest to the proposed technical entity is a device for determining the location of rolled products, containing sensors for the presence of the product. A counter, serially connected registers, the input of the first of which is connected to the output of the counter the inputs of the display elements, the output of the counter is connected to the input of the first decoder, the outputs of the registers are connected to the inputs of the corresponding decoders, the output of the first sensor The availability of the product is connected to the input of the counter, and the outputs of other sensors are connected to the control inputs of the registers. In this device, the location of the product is determined by the location of its front end with an accuracy of the length of the section where it is located [23.

In this device, the location of the product is determined by the location of its front end with the exact-tew to the length of the section where it is located [21

However, the product number can be 5 recorded in several registers at once, as a result of which it is impossible to determine the location of the product and an additional analysis of the indications of indicators is required to determine the actual position of the front end of the car. This especially makes it difficult to transfer information from the device in question to automatic devices. one

Example.

In the initial position, there are no products on the mill and all the registers and the counter are in the zero state and only one 2 products are rolled. At the entrance to the mill, the counter records the number one and as the product advances, this number one is fixed sequentially on the first, second and further registers. Thus, ^2, when the product leaves the mill, the number one is fixed on all registers, although there are no longer any products on the mill.

The purpose of the invention ~ improving the accuracy of devices. 3

This goal is achieved by the fact that the device for monitoring the location of rolled products, containing greatness sensors, a counter, ₃ serially connected registers, the input of the first of which is connected to the output of the counter, according to the number of sensors of product availability, display elements and decoders, whose outputs indication, the output of the counter is connected to the input of the first decoder, the outputs of the registers are connected to the inputs of the corresponding decoders, the delay elements are introduced and, according to the number of sensors in the presence of the memory triggers, the output of the first of which is connected to the counter input and the control input of the first display element. The remaining memory trigger outputs are connected to the control inputs of registers and the corresponding display elements, the outputs of the product availability sensors are connected to the first memory trigger inputs, , except for the first, are connected via delay elements to the second inputs of memory triggers.

The drawing shows the block diagram of the device.

A device for monitoring the location of rolled products contains sensors 1 product availability, the register 2 position of the product, the counter 3 block 4 registers, block 5 of the display, delay elements 6, memory triggers 7, registers 8, decoders 9,

⁰ display elements 10.

In the drawing as an option shows the circuit reset the last trigger 7 of the memory to its original state. This trigger can also be collected by an additional sensor installed after the last move by the sensor or by other means. In addition, if necessary, information from memory triggers can be used to transfer it to automation systems. Information single. The state of memory triggers 7 indicates that there is a front end of ⁵ Delia with a sequence number represented in the register in this area. Information about the number on the display elements 10 appears only when the memory trigger relating to this area,

® is in a single state, i.e. on this site is the front end of the product.

The device works as follows.

5 In the initial state, when the product in the production line is absent, all the triggers 7 of the memory of the register of the 2 position, the counter 3 and the registers 8 are reset to the initial state and,

¹⁰ therefore, the display elements 10 of the display unit 5 do not flash anything. When the product enters the zone of the first sensor 1 of the presence of the product, the latter is triggered and thereby

> 5 translates the first trigger 7 of the memory into one state, the counter 3 counts one, and at the first control input of the display unit 5 there appears an enabling signal from the first trigger> 0 pa 7 of the memory. On the corresponding display element 10, the number one lights up.

Upon further advancement of the product, the next sensor 1 ‘5 of the product availability is triggered. With eFom, the first memory trigger 7, regardless of the state of the first memory sensor 1, returns to its initial state

5 9P423 6

the next trigger 7 of the memory is transferred to one state, and the first register 8 records the number one of the counter 3 · At the enabling input of the first display element 5

, 0 the signal disappears, and a similar signal appears on the enabling input of the next display element, the number one lights up on the display of the second section. As the monitored product moves along the sections, the indication element of each section lights up sequentially. Therefore, the position of the product is uniquely determined. 'five

When the next product enters the zone of the first sensor 1 of product availability, the counter 3 counts one more and writes the number two, which is similarly moved from one display element to another, unambiguously determining the position of the second product. The position of all subsequent products is determined in the same way. 25

. A device for controlling the location of rolled products allows you to reliably, unambiguously and continuously have information about the location of each of the products that are on the line.
