Description

The movement of the given points of 6 intergofan gaps through the axis 7 of the molding stand 1, and the sensor 8, which gives out the number of pulses proportional to the angle of wrench for each roll 9, is the given point near the cutting tool. The output of sensor 5 is connected with the S input of the trigger 10 of the base distance. The output of the sensor 8 UGA rotation of the roll forming the cell connected to the inputs of the keys 11,12. The second output of the trigger 10 of the base distance is connected to the second input of the key 11. The second input of the key 12 is connected to the direct output of the trigger 13 for starting the operation of the gala control of the corrugation pitch. The output of the key ll is connected to the input of the base-distance reference node 14, the output of which is connected to the R-input of the trigger 1O of the base distance, S - to the input of the trigger 13 start. La operation of the control unit of the step of corrugations and the second input of the control unit of the step of the corrugations 15. The output of the key 12 is connected to the first input of the control unit of the step of the corrugations. The output node is the output of the proposed device.

The device works as follows.

In the initial state, the triggers 10.13 are in the zero state and the keys 11, 12 are closed. The first pulse signal from sensor 5 is emitted at the moment when. The first predetermined point 6 intersects the axis 7 of the forming stand 1. This signal 10 is set to one and the pulses from the angle sensor 8 of the forming stand roll are passed through the public key 11 to the input of the reference distance reference 14. .

Node 14 starts counting the path traversed by the first point 6 from the axis 7 of the forming stand 1. When the first point b passes the path L and reaches a predetermined point near the volatile cutting device, the node 14 will generate a pulse signal. By this signal, the trigger 1O is set to zero, and the trigger 13 is set to one, the corrugator control node 15 is reset, and a pulse signal appears at its output. At the same time, the key 11 is closed and the wrench 12 is opened. The corrugator pitch control unit starts counting the pulses from the sensor 8 of the twist of the roll of the forming stand. With the inclination in the node the number of pulses N. equal:

N

sh.

where N is the number of pulses emitted by the sensor, 8 and one revolution of the roll of the form cage.

P is the number of corrugations molded by the cage on the strip per one roll of the roll forming the cage;

a pulse signal is output from its output, Lf | , Which is the output signal of the device.

In a further knot, a pulse signal U will be emitted each time the strip passes a distance from the point equal to the length of the corrugation. In this case, the specified points of 6 intergammal intervals will cross the specified point near the volatile cutting device.

In order to eliminate the possibility of an error after the first reading of the L values, which may occur due to the waviness of the strip at the beginning of the coil, as well as to eliminate the accumulation of error from cutting to cutting, the operation cycle of the node 14 is periodically repeated. So, for example, after the end of the first cycle of operation, when the first point 6 on the strip has reached the point, the second cycle of operation will begin after the next point 6 on the strip crosses the axis 7 of the forming stand 1. At the same time, the sensor 5 will give a signal to the 5 trigger input 10 and the key 11 will be opened with a signal from its direct output. After the node finishes calculating with a node of 14 magnitude, the signal from its output will reset the control box of the corrugations. Thus, with each subsequent reading by node 14, an amendment to the operation of the node will be made. In the future,

ma works the same as previously described.

Using as a source of information on the movement of the strip of the angle of rotation of the roll of the forming stand will eliminate errors associated with

the error of the work of the following rollers when counting the cut length.
