The invention relates to automatic and electronic devices for counting objects transported in some way, and can be used in various branches of the national economy, in particular for counting forgings and stampings in the quartz-thermal industry.

The aim of the invention is to increase the accuracy of the counting and simplify the device.

The drawing shows a functional diagram of the proposed device.

The delay element 4 confirms the state of the trigger 5, a low voltage level is present at its inverse output, the corresponding O. The signal from the output of the second sensor 2 does not pass to the input of the counter 7 and no counting occurs.

If an item passes the first sensor 1 more than twice, but the second sensor 2 does not pass, the counting does not occur. Since the pulses from the output of the first sensor 1, starting from the second, do not pass to the count input

A device for counting objects Hera 5, i.e. trigger toggles

holds the first and second sensors 1 and 2, the element And 3, the element 4 delay, trigger 5, the element AND-NOT 6 and the counter 7.

The device works as follows.

Before starting work, the initial installation of the trigger 5 is made in the single state, and the counter 7 is in the N / L (the initial setting circuit is not

only once and the device is prepared to receive a signal from the second sensor 2.

In the case when the object for some reason stops at the first sensor 1, the second sensor 2 is affected by the interference signal or the previous product, the counting does not occur, since the trigger 5 is set to

shown). The item moves from the first such state when there is 1 at its inverse output, and only on the falling edge of the pulse arriving at the counting input trigger (hera 5, this trigger can switch sensor 1 to the second sensor 2. When the object passes the first Sensor 1 generates a signal 1, which is fed to one of the inputs of the element AND-NOT 6, at the second input of which 30 is present, since the trigger 5 is set to one, which ensures the passage of the pulse from the output of the first sensor 1. Inverted output pulse of the element - NAND 6 is fed to the counting input trigger 5, and the switching edge 5 switches to the zero state along the trailing edge. The voltage level corresponding to 1 is fed to input 0 of the IZ element connected to the inverse trigger output 5 When the subject passes the second sensor 2, a pulse is generated, which is fed to the second input of the IZ element, causing it to trigger, and the signal from the output of the I 3 element, is fed to the input of counter 7, increasing its content by one. The signal from the output of the second sensor 2 passes through the delay element and sets the trigger 5 to its initial state. Thus, the device is prepared for further (Work.

Chit.

If the object stops at the second sensor 2 and acts on it, and the first sensor 1 is affected by another product or an interfering signal, the counting also does not occur, since at the installation input, trigger 5 is present O and pulses through the counting input trigger 5 does not switch .

Thus, the device allows the counting of products that appear sequentially at the first and second sensors, and eliminates the counting in any other cases.

The use of the device in forging and thermal production with installation on forging and pressing equipment allows for more accurate accounting of manufactured forgings and stamps, which, in turn, reduces the loss of metal in the shop - warehouse - customer chain.

Invention Formula Device for counting items, When returning the item, first post-55 holding the first and second sensors. It goes to the second sensor 2, at the output of which a signal 1 appears. But since the trigger 5 is in the unit state, the pulse from the output And element, delay element, trigger and counter, the output of the second sensor is connected to the first input of element And, the output of the delay element is connected to only once and the device is prepared to receive a signal from the second sensor 2. In the case when the object for some reason stops at the first sensor 1, the second sensor 2 is affected by the interference signal or the previous product, the counting does not occur, since the trigger 5 is set to 30 - 0. 0 Chit. If the object stops at the second sensor 2 and acts on it, and the first sensor 1 is affected by another product or an interfering signal, the counting also does not occur, since at the installation input, trigger 5 is present O and pulses through the counting input trigger 5 does not switch . Thus, the device allows the counting of products that appear sequentially at the first and second sensors, and eliminates the counting in any other cases.
