    A machine (101) for automatically roughing the cement margin (103) of a footwear upper assembly (104). The machine includes means (51) for supporting the footwear upper assembly (104) by a mechanism (4,5,6) capable of applying to the upper assembly (104) rocking movement, translational movement, and rotational movement. A roughing tool (41) is provided, as well as means for applying a combination movement to the upper assembly. Simultaneously, roughing is effected along the shoe margin (103) by the roughing tool (41). The combination of movements serves continuously to present a new roughing surface to the roughing tool (41) in the course of roughing, resulting in uniformity of roughing. The rotational movement serves to cause the roughing tool (41) to track the cement margin (103) with a determined orientation therebetween as the cement margin (103) moves past the roughing portion (41A) of the roughing tool (41).

    A bracket 53 on which the rollers are placed is mechanically connected to the input of the converter 54, and the lever 43 is kinematically connected to the converter 55. To press the rollers 36 and 37 to the glued edge, a pneumatic cylinder 56 is used.
    The blank 4 has a blind hole for insertion of a cylindrical pin 57 mounted on a rotary spindle 58, which is part of the turret 6. The spindle 58 is mounted to rotate (by means of compressed air) and hold the blank 4 to the stand 59
    For proper operation of the machine, the relative position of the rollers 36 and 37 relative to the pins 48, 49 and 41 is especially important. The longitudinal axis of the rollers 36 and 37 forms an acute angle with the longitudinal axis of the pins 48, 49 and 41.
    The machine works as follows, eom.
    The operator sets the workpiece 4 on the support 5 and, using the control panel 28, turns on the program control block 29. In the first period of operation of the machine, the workpiece 4 is stationary, the drives set the brush 12, the rollers 36 and 37, the pins 48, 49 and 41 to the predetermined initial position. Information from the sensors on the initial state of the brush, rollers and other elements of the machine suggests that you can begin the process of stripping the edge.
    During the second (short-term) period, information from the outputs of the sensors 22-27 is used to adjust the position of the workpiece 4 relative to the 12 "brush. This is necessary in order to ensure a certain orientation between the brush 12 and the workpiece 4 during their relative movement during processing. wherein the edge 3 between the glued edge 2 and the side 60 is oriented to a predetermined position due to the rotational movement of the turret 6. Due to this orientation, the brush 12 always appears to be perp Dikulja edge angles 2 regardless of the position of the workpiece 4.
    During the third and fourth periods, the required square of abrasive glued is maintained.
    edge of the workpiece. During the third period, the brush 12 is brought into contact with the bottom of the workpiece. During the fourth period, the amount of skin to be removed is additionally regulated when the edge of the workpiece is stripped.
    Let us consider in more detail these periods of the machine.
    The rollers 36 and 37 catches along the glued edge and exert pressure on it provided by the pneumatic cylinder 56. Both rollers 36 and 37, installed on opposite sides of the brush 12, track the unevenness of the glued edge in the process of translational movement of the workpiece 4 Moving rollers 36 and 37 cause movement bracket 53, which is converted into an electrical signal using a potentiometer 47. This information is used to control the swinging movement of the support 5. The rollers 36 and 37 can also be rotated around the axis 38. The magnitude of this gates is converted into an electrical signal by means of potentiometer 40 and is used to adjust the depth of penetration of the brush 12 in the taped region 2 for eliminating the brush exit edge of the edge 2, and 3 damage insole.
    The position of the pins 48 and 49 carries information about the angle of rotation of the turret 6 and, therefore, the workpiece 4. The differential output signal characterizing the relative position of the pins 48 and 49 is used for the angular orientation of the workpiece 4 relative to the brush 12. Almost always the extension of the pin 48 is accompanied by retraction pin 49 and vice versa. These movements are converted by potentiometers 50 and 51 into electrical signals controlling the wire 8.
    The pin 41 is moved reciprocally in the longitudinal direction, depending on the angle of rotation of the workpiece 4. This movement is converted into an electrical signal by means of a potentiometer 42 controlling the drive 16.
    The contour of the workpiece 4 in different workpieces is not the same. As a result, without taking special measures during machining, the brush 12 may damage the workpiece. To eliminate this

    Storing the workpiece, a torque sensor 14 is used. The output signal of the sensor 14 is proportional to the load on the shaft of the DC motor 13. The output signal of the sensor 14 acts on the control unit 15, which changes the speed of rotation of the electric motor 13, and consequently. Therefore, the rotational speed of the brush 12 is that the output signal of the sensor 14 acts through the control unit 21 on the actuator 19, which changes the depth of insertion of the brush 12 into the glued edge.
    During the fifth period (the moment when the brush approaches the precise or toe-bending of the workpiece), the machining process slows down. After passing these sections, the processing is repeated as described above.
    A characteristic feature of this machine is that by making the drive 8 of rotation of the workpiece reversible with the possibility of angular displacement of ± 360 °, the workpiece can be processed both in the direction of rotation clockwise and against it.
