    The invention relates to a method and apparatus for molding multilayer soles to the upper parts of shoes.
    The purpose of the invention is to improve the quality of manufactured shoes by improving the accuracy of manufacturing and ensuring the automation of processing processes.
    In Fig. · 1 shows a General view of the installation for injection molding of soles with a round rotary table; in FIG. 2 - a device for molding the soles of the upper part of the shoe according to the invention;
    in FIG. 3 is a side view of the upper part of the shoe with measuring elements and a mold.
    Shown in FIG. 1, the injection molding apparatus comprises a rotary table 1 with injection molding positions 2 evenly distributed around the circumference 2. At each injection position 2, an injection molding apparatus is arranged. Each position has a block 3, on which the workpiece top 4 is stretched, the bottom punch and counter punch 5 and the forming elements 6 and 7. Each injection position reaches its original position after 15 revolutions of the table. Positions are indicated by reference numbers 8. The injection molding device is arranged around the circumference of a rotating table. The device for injecting material 9 is located with the possibility of radial movement to the rotary table 1 and with the possibility of connection with each injection position, for example, in the drawing with the position 8. After rigid connection with this position, an elastomeric mass for the sole is injected into its injection mold.
    The device 10 serves to mix and prepare the polyurethane and is also located with the possibility of radial movement relative to the rotating table 1.
    With each rotation of the rotary table 1, the device 10 for mixing and preparing polyurethane can be connected to one of the working positions, for example, from 8 (in Fig. 1) so that the material for molding the sole is pressurized in mold 8 of this position.
    The inner and outer soles are cast at the same time and in the zone it is served as finished shoes for the release from the installation.
    At one of the working positions, for example at position 8, the contour of the workpiece top 4 is measured by means of a sensing element 11 operating in a contact or non-contact manner and connected by a wire 12 to the measuring system 13. This measuring system is used to measure the geometry of the block and the shape related thereto, and also for determining the zero point of coordinates and the tangent angle, starting from a given zero point of coordinates of the workpiece top. The obtained values are stored in the storage device 14. The rotary table 1 is rotated to position another block of the workpiece upper shoe, having the same dimensions.
    The storage device 14 is connected to a computing device (computer) 15, which controls the robot 16. The robot 16 has a shoulder 17, on which the cutter 18 can be mounted to roughen the molded sole or tool for applying glue and / or removing sag. The shoulder 17, respectively, the milling cutter 18 is pivotally mounted in such a way that it can move around the circumference in the area of forming the sole for all pads 3. Outgoing during milling, as well as when removing sagging chips are sucked off by means of a suction device, and (in Fig. 3) is shown only suction hose 19.
    The molding device operates as follows.
    The data of the sealing edge of the mold determined by the measuring system, the sealing half of the mold relative to the workpiece of the upper shoe or relative to the shoe are collected and stored along with the values of the shoe in this zone. The corresponding storage device has multipliers with which the pad sizes of one particular shoe size are multiplied in order to obtain the pad sizes of the same type, but of a different size. The storage device is associated with a computing device designed to receive control commands for the robot 16.
    In the event that the form falls into the operating zone of the robot 16, by means of the said measuring elements, it is established which position, respectively, the inclination angle in space is occupied by the existing block. If necessary, a centering pin can be used for this, with which you can set the zero point of coordinates. If the zero coordinate point is determined, you can set or calculate using the stored values the specified curve along which the processing tool 18 should move when taking into account the size of the block 3. The corresponding control commands are sent directly to the robot 16, namely its shoulder 17. Thanks to this execution, it is possible to carry out processes roughening, applying an adhesive film and / or removing sag when molding the sole with an accuracy not yet achieved by any known method, and device for its holding.
