Device for applying a pattern on the sheet product
(57) Abstract:Usage: for application of the pattern by a stream of abrasive material through the stencil mask sheet product large area. The inventive device includes a stencil mask with ferromagnetic and resistant to abrasive material coating, a support in the form of a guide with suction cups and a groove with a rail, a carriage with a vertical stand and a tool for installation of the stencil mask. The tool is made in the form of a sleeve with a rod passed through the sleeve and through the vertical groove of the rack with a handle rigidly connected to the pivot plate with the electromagnet DC, having means for changing the direction of the magnetic field, and installed the ferromagnetic plate. The carriage and the rod are stoppers for the installation of the stencil mask in the specified coordinates relative to the product. 6 C.p. f-crystals, 6 ill. The invention relates to a device for applying a pattern on flat products a large area, such as glass.A device for applying a pattern on a sheet article containing the stencil with Windows for applying through their pattern on the product, support and securing products and stencil .In Fig.1 shows a device for applying a pattern on the sheet product, a plan, and Fig.2 - the same, lateral view; Fig.3 - section a-a in Fig.1 (installer tool stencil); Fig.4 - section b-B in Fig.1 (suction) of Fig.5 - section b-b of Fig.2 (installation of the carriage on the rail), and Fig.6 - stencil - mask section.The device consists of a base in the form of a horizontal guide 1 is placed on it to move the carriage 2 having a vertical rack 3 tool 4 installation of the stencil mask 5.The horizontal guide is circular in cross-section beam, the ends of which is equipped with vacuum suction cups 6 and along its surface formed by the toothed rack 7 slot 8. Each vacuum suction is performed as part of the sphere of elastic material and has an attachment surface 9 for installation on window glass. It is fixed to the beam by means of the pipe 10 with the spring loaded ball valve 11 having a push rod 12 to its management.The carriage consists of a bracket 13 mounted on it to cover the beams supporting rollers 14. The bracket is pivoted a spring-loaded two shoulders lever 15, one leg of which includes a groove 8 and engages with subch the Vertical strut has a longitudinal through groove 16 and the rack 17, and at the end of the support roller 18 mounted with the possibility of fixed rotation around the axis of the rack to change the gap between the counter and the product. The means 4 for mounting the stencil mask is made in the form installed on a vertical pole sleeve 19, through which and through the groove of the rack skipped the rod 20 with the handle 21, the spring-loaded sleeve 22 with a lever 23 having a locking tooth 24, passing through the sleeve 19 to log in engagement with the gear rack rack with lock the vertical movement of the sleeve 19. At the other end of the rod formed by the pins 25 for the installation of the stencil mask.The sleeve 19 can be rotated around it installed plate 26 rigidly connected with the rod 20, and on the other hand is a spring-loaded ball detent 27 is connected by a bracket 28 with the said rod for corner fixing plate relative to the sleeve. The plate is concentric with the rod attached to the electromagnet 29 and on the contour elastic protective screen 30. The electromagnet is placed in a protective holder 31 to prevent contact with the abrasive material, which are connected to plate 32 of ferromagnetic material with a window 33 for passage of the pin rod and a window 34 on its consolodate abrasive material (not shown) on the ball bearing 36 and the outlet 37 of the exhaust abrasive.The stencil mask is made of at least a single layer of sheet 38, coated on one side with a layer 39 of ferromagnetic, and the other layer 40 resistant to the abrasive (carbon) material. The sheet has a guide bushing 41 for the installation of the stencil mask on the pin and the box 42 to process through it the product of the air-abrasive stream.For the application of the pattern guide 1 with the stand 3 is mounted on the display glass. To do this, click on the rods 12 ball valve 11 for the message of the internal cavity of each of the vacuum suction 6 with the atmosphere, press the guide with suction cups to the surface of the product and release the rods. Created under the vacuum suctions securely holds your device on the display glass. After that, by turning the support roller 18 around the axis of the rack installing the same gap between the product and guide with vertical stand. Then on the pins 25 are installing bushings 41 stencil mask 5. For this purpose, two shoulders lever 15 is removed from the groove 8 and out of engagement with the teeth of the rail 7 and turn the vertical rack together with the carriage 2 around the axis of the guide. Setting the stencil mask bushings 41 on the pin 25, the counter returns to the initial operating position. Then include the pins 25 stencil mask plate 32 (non-operating position of the stencil mask) or when changing the polarity of the circuit of the electromagnet is discarded from the plate 32 and is firmly pressed against the display glass. Optionally, to enhance the contact of the stencil mask to display the glass with the back of his hand set against the plate 32 a permanent magnet (not shown).To move the stencil mask in another coordinate point products work overcomes two shoulders lever 15 and moves the carriage 2 horizontally in a given vertical coordinate, and then, by releasing the lever 23 moves the sleeve 19 to the vertical at a given coordinate. The angular displacement is produced by the rotation of the lever 21 about the axis of the rod 20, and the ball retainer 27 passes through the holes of the sleeve, locking the position of the stencil mask, a multiple step holes.After the installation of the stencil mask in the given coordinates, through nozzle serves abrasive material and form on the product pattern. If the window stencil mask exceeds the torch nozzle, the latter mounted on a ball bearing and a pattern is formed by sequentially rotating nozzles managing lever. To remove abrasive material casing 30 is communicated with the pipe 37 with istochnoye products large area. 1.

SUBSTANCE: material for printing forms is made only from film of thermo-plastic resin by usage of polyether film in such a way, that aperture, through which paint may permeate, can be thermally perforated without increasing power of thermo-printing head. Film is a thermo-sensitive material for stencil printing forms 12, having given thickness, and consists of stretched mylar film or stretched film with low melting point, produced by copolymerization of polyethylene therephthalate and polybutylene therephthalate. A set of smallest raster cells 14 is formed on one side of film by transfer of template. Transfer of template may be performed under working pressure 104·102(m-t)/(m-g) Pascals or higher, when working temperature is t°C, melting point temperature of film is m(°C), and temperature of film vitrifying is g(°C).
EFFECT: decreased power of thermo-printing head, facilitated operations with film.
