(54) MARKING DEVICE MANAGEMENT SYSTEM

one

The invention relates to a device for marking metals, in particular, rolled sections and sheets, as well as parts from non-metallic materials.

A control system is known for a marking machine containing tool position sensors, a comparison unit, an information input unit 1. However, this device does not allow marking to be performed by continuously building any marking mark, but only by applying a finished marking placed on the disk.

A known marking device control system comprising an information input unit electrically interconnected, a comparison unit, a bit polling unit, an amplifier, a tool horizontal control unit, and a control board 2. The disadvantage of this device is complexity and low reliability.

The purpose of the invention is to increase the reliability of the device.

The goal is achieved by the fact that the control system of a marking device containing electrically

interconnected information input unit, comparison unit, one-by-one polling unit, amplifier, control unit for horizontal movement of the instrument and control board, equipped with position sensors of the control unit for horizontal tool movements associated with the comparator unit, clock sensor associated with a polling unit; and a vertical tool movement unit associated with a horizontal tool movement control unit and a polling unit.

FIG. I depicts a general view of the marking device; in fig. 2 - device control system block scheme

  for labeling; in fig. 3 is a stylized figure that the marking tool describes.

The marking device contains a marking head 1, in the housing there are mounted a food tool and a locking mechanism (not shown), a vertical movement mechanism, made in the form of a cross member 2 mounted on the device case

with the possibility of vertical movement and connected through a screw pair 3 with a drive 4, a horizontal movement mechanism made in the form of a carriage 5 installed with the possibility of horizontal movement on the crossbar 2. On the carriage 5 there is an actuator 6 connected through a drive shaft 7, cylindrical gear wheels 8 and 9, a conic pair 10, gear 11 with a gear rack 12 fixed on crossbar 2, and through gears 8, 9 and 13, cams 14, 15 and hooks 16 and 17 fixed on carriage 5 with the possibility of mutually perpendicular move - with marking head 1. Flags 18 and 19 are attached to the drive shaft 7.

The control system of the marking device contains a comparison unit 20, some of the inputs of which are connected to the outputs of the information input unit 21, others with shaft position sensors 22-29 mounted on the carriage body 5 and connected to the drive shaft 7 via flag 19. The number of these sensors equal to the number of links constituting the stylized figure. The output of the comparator unit 20 via the amplifier 30 is coupled to a tool fixing mechanism, which is controlled by a solenoid 31.

The inputs of the information input unit 21 are connected to the outputs of a polling unit 32 of a given program, one input of which is connected to a clock pulse sensor 33 installed on the carriage 5 and connected via flag 18 to the drive shaft 7, the other two to the first outputs of block 34 control of the vertical movement mechanism and the block 35 of the horizontal movement mechanism control. The second output of the vertical movement control unit 34 is connected to the input of the horizontal movement control unit 35, the second output of which is connected to the input of the vertical movement control unit 34 The third output of the vertical movement control unit 34 is connected to the drive 4 of this mechanism, the third output block 35 for controlling the horizontal reversing mechanism - with the drive 6 of the corresponding mechanism. A control board 36 is connected to the information input unit 21.

The control system for the marking device operates as follows.

Before starting work, the control system is powered on, all the blocks are prepared for operation, and the marking device is set to its original position, with the cross member 2 in the extreme upper position, and the carriage 5 with the marking head 1 in the extreme left position.

In the information input unit 21, a program for writing a predetermined code is typed, the signs of which are displayed on the control panel 36. After the installation of the component in the working area of the device, the marked part serves

The start signal to block 34 controls the vertical movement mechanism. Unit 34 provides control signals to the actuator 4 and to the input of the unit 32 of the serial polling of a given program. In this case, the actuator 4, through the screw pair 3, lowers the list 2 with the carriage 5 installed on it, and the 32 unit of the serial polling of the specified program is prepared for operation. When the gap between the writing instrument of the marking head 1 and the surface of the marked part reaches a predetermined value, the vertical movement control unit 34 turns off the drive 4 and outputs control signals to the inputs of the horizontal movement control unit 35 and the second polling unit 32 of a given program.

The horizontal movement control unit 35 generates signals, one of which turns on the actuator 6, the other enables the operation of the block 32. one-by-one interrogation of a given program. The actuator 6 drives the shaft 7, whose rotation with the help of gears 8 and 9 of the conical pair 10, the gear 11 with the gear rack 12 converts i the forward movement of the carriage 5, and with the help of the gear 8, 9 and 13, cams 14 and 15, t g 16 and 17 - in the movement of the marking head 1 on a closed loop. As a result of the addition of these movements, the marking tool describes a stylized shape above the surface of the part being marked (see FIG. 3).

With the beginning of the movement of the drive 6, the flag 18 acts on the sensor 33 clock pulses, which gives a pulse to the input of block 32 of the serial polling of a given program. Block 32 of a polling of a given program generates a signal in block 21 for entering information, allowing the issuance in block 20 of a comparison of the sign of the first digit of the programmed marking code. Box 19 for one rotation of the shaft 7 sequentially affects the sensors 22-29 polo 1 {eni shaft corresponding to sections 37-44 stylized figures. The signals from the sensors 22-29 come to the comparison unit 20, which in the areas corresponding to a given sign, produces a signal coming through the amplifier 30 to the solenoid 31. The solenoid 31 lowers the writing instrument until it touches the marked surface on which

5 one of the elements of the mark to be marked is applied. For example, for marking the number 3 (see Fig. 3), solenoid 31 is triggered sequentially in sections I, III, Y, U1,, yill, which corresponds to the activated sensors 22, 24, 26, 27 and 29. At the next rotation of the shaft 7 again The sensor 33 clock pulses, which corresponds to section 45. Starts marking the character of the next bit of the marking code. At the end of the marking of a given code, the horizontal movement control unit 35 reverses the actuator 6 and outputs to the inputs of the vertical movement control unit 34 and the serial polling block 32 signals about the end of marking. As a result, all marking device mechanisms are reset, and the control system is prepared for the next marking cycle. The proposed technical solution makes it possible to simplify the control system of the marking device, increase its reliability by eliminating the memory block, reducing the number of amplifiers, and also due to the fact that the number of shaft position sensors does not depend on the number of marked signs, but on the constituent links figures.
