Definitions

  • the invention relates to a vector brush according to the preamble of patent claim 1.
  • a device is already known from EP-A-0 229 935, but is only suitable for forming an incision in a film, and not for severing films.
  • a cutting device for foils is known, with which letters, characters or the like. can be cut out of a two-layer film in order to create signs, masks for painting and spraying work, lettering, etc. to manufacture.
  • the known cutting device has a housing with two cheeks arranged at a distance from one another, between which the film web is guided by tractors. Between the cheeks extend guide rods on which a carriage carrying the cutting tool is mounted. The carriage is thus moved across the track in the Y direction. In the X direction, the film web is moved by the tractors, which can not only move the web in a controlled manner, but also back.
  • a similar cutting device is known from US-A-4,467,525, in which the cutting tool can also be replaced by a writing tool.
  • the carriage is electronically controlled by a control unit. With this known device, however, it is only possible to either cut or draw.
  • a so-called air brush is already known as a drawing device, with which a fine paint spray cone can be metered onto a base.
  • the ink is supplied through a central channel in which a needle sits, which increases or decreases the cross-section of the discharge opening and thereby regulates the ink flow.
  • the discharge opening is surrounded by an air duct into which compressed air with a pressure of approximately 0.5 to 2.5 bar is supplied.
  • the compressed air tears the paint out of the discharge opening and forms a fine spray cone.
  • the diameter of the spray cone sprayed on a base depends on the distance from the discharge opening to the base.
  • the paint spray cone can be adjusted over a relatively wide range by suitably selecting this distance from the base and by adjusting the needle in the discharge opening.
  • a disadvantage of the known air brush is that it has not yet been possible to use it under computer control.
  • a disadvantage of the known cutting devices is that they can either only cut or only draw, so far no air brush has been used in the drawing operation, since these could not be easily used in the carriage of a cutting device because of their paint and air connections, as is possible, for example, for an ink pen.
  • Another advantage of the invention is that the vector brush can be exchanged quickly and easily if faults should occur or if a new color is desired.
  • the paint container can preferably be replaced alone or together with the air brush.
  • the device shown in Figure 1 is similar in its basic structure to the cutting device from DE-C1-37 29 208, so that neither details of the control nor explanations about the input of the control commands or the like. required are. However, reference is expressly made to the mentioned patent specification.
  • a housing 1 which has two side cheeks 6, 7, between which there are guide rods 10 and 11 for a carriage 9 movable along these guide rods.
  • Endless toothed belts 12, 13 are fastened to the slide 9 and serve, in a manner not shown, but usually, to move the slide 9 back and forth in a controlled manner along the guide rods 10, 11.
  • the movement of the carriage 9 is controlled by commands which are entered into the control unit (not shown) of the device via a keyboard 2 which is connected to the cutting device by means of a cable 3 and a plug 4.
  • the control unit is also connected to program cassettes 5, which are interchangeable and can be used to generate fonts and symbols, for example.
  • the control unit can correspond to that from US-A-4,467,525. It is pointed out that instead of the program cassettes 5, a computer can also be connected, on the screen of which the control commands can be displayed.
  • a carrier roller 8 via which a web of material to be cut, usually guided in a manner not shown, but corresponding, for example, in US-A-4,467,525, usually guided a two-layer plastic film and not during the machining process by reciprocating means shown tractors is moved in a coordinate (X direction) of the cutting course to be produced, the carrier roller 8 executing a corresponding rotary movement about its longitudinal axis.
  • a cutting tool can be moved back and forth in the guide bush (not shown) in the direction of the longitudinal axis of the guide bush and is additionally rotatably mounted, so that the cutting element provided at its front end can be moved between a raised position and a lowered working position. In this position, the cutting element is in cutting engagement with the film material located on the carrier roller 8. Details are explained in DE-C1-37 29 208.
  • a pivotable, one-armed lever 17 is also attached, which carries the cutting tool at its free end.
  • a leaf spring 21 presses the cutting tool, not shown, against the film material to be cut.
  • An eccentric shaft 14 serves to raise or lower the cutting tool. The eccentric shaft 14 is controlled via a stepper motor, not shown.
  • FIGS. 2 and 3 show a schematic view of the vector brush 20 attached to the end face of the carriage 9 in FIG. 1.
  • the vector brush 20 has an air brush 22 which is in flow connection with a paint container 26 via a hose 24 .
  • the paint container 26 is fastened by means of a bracket 27 to a slipcase 28 which laterally surrounds the carriage 9 with two arms 30, 31 (FIG. 3) and with claws 32, 33 provided at the ends of the arms 30, 31 in vertical guide grooves 34 , 35 of the carriage 9 engages.
  • a first clamping screw 36 is screwed through the slider 28 and presses with its tip against the end face of the slide 9. As a result, the slider 28 is clamped on the slide 9.
  • the solenoid valve 38 which controls the supply of compressed air, which is supplied via a hose 39 with a pressure of approximately 0.5 to 2.5 bar, to the air brush 22.
  • the solenoid valve 38 is of a type known per se and receives its power supply via feed line 41, which lead into a connecting piece 42 which is attached to the side of the solenoid valve 38.
  • the solenoid valve is known per se. It is available from FESTO under the designation 30 217 MZH-3-04 and controls a first channel 43, at the free end of which the connecting piece for the hose 39 is located.
  • the first channel 43 merges into a second channel 44, which is connected to the air brush 22.
  • the valve cone of the solenoid valve 38 is located at the transition point from the first channel 43 to the second channel 44.
  • the air brush 22 rests in a semicircular recess in a lateral slip extension 40, to which it is clamped by a bracket 46 with the aid of a second clamping screw 37.
  • the bracket 46 is best seen in Figure 3 in plan view. It has the shape of a U-profile with inwardly drawn leg ends 47, 48, which engage in vertical guide grooves 49, 50 of the slipcase extension 40.
  • a wall of the bracket 46 is provided with a cutout 52 which is open at the bottom, so that the bracket 46 can be pushed over a paint connection piece 51 or the paint hose 24.
  • the air connection piece of the air brush 22 is inserted into the second channel 44 with small sealing rings, for example O-rings, in order to establish the compressed air connection.
  • the seal between paint hose 24 and paint connection piece 51 is not so critical since the paint is supplied without pressure. It is sufficient if the paint hose 24 is fitted snugly or tightly onto the paint connection piece 51 on the air brush 22.
  • FIGS. 2 and 3 is only intended to show the arrangement and assignment of the individual parts of the vector brush 20 schematically.
  • the needle 54 on the air brush can also be seen in FIG. 2 and is used to adjust the opening cross section of the air brush nozzle 55.
  • FIG. 4 shows a further exemplary embodiment in which the ink container is integrated in a cassette 62. Parts that correspond to the other figures are provided with the same reference numerals.
  • the slipcase 28 ' also carries the solenoid valve 38 here, which controls the connection from the first channel 43 to the second channel 44.
  • the compressed air hose 39 is connected to the first channel 43, in which it is plugged onto a connecting piece.
  • the air brush 22 connects to the second channel 44, again through a connection piece provided on the air brush, onto which sealing rings, advantageously O-rings, are attached.
  • the connector 42 for the electrical leads 41 is attached to the side of the solenoid valve 38.
  • the slipcase extension 40 is provided with a vertical groove 50 on only one side. The other side is smooth.
  • On the end face 60 of the slide 28 ' is the cassette 62 with a complementary to the end face 60 shaped rear wall 61'.
  • the front wall 64 of the cassette 62 is flat except for a vertical groove 49 'which serves to engage the leg end 47 of the bracket 46'.
  • an ink channel 24 ' is incorporated into the cartridge 62 in the cartridge 62, which leads from an ink cartridge 26' to the paint connection piece 52 of the air brush 22.
  • a sealing ring is also attached to the paint connection piece 51 on the air brush 22 in order to achieve a seal of the paint channel 24 '.
  • the cassette 62 is provided in the region of the compressed air hose 39 with an upwardly open slot 63 in order to enable assembly on the slipcase 28 '.
  • a third clamping screw 65 is inserted through the cassette 62 near the cartridge 26 'and screwed into the slipcase 28' to secure the cassette 62 to the slipcase 28 '.
  • the cassette 62 is assembled as follows: First, the compressed air hose 39 is plugged onto the connecting piece on the first channel 43. Then O-rings are placed on the two connecting pieces of the air brush 22 and these are inserted with their air connecting pieces into the second channel 44, so that they fit snugly against the semicircular recess of the slipcase extension 40. Then the cassette 62 is pressed against the end face 61 of the slide 28 ', so that the paint connection piece 51 of the air brush 22 penetrates into the paint channel 24'. Now the bracket 46 'with its leg ends 47, 48 is pushed from above into the guide grooves 49' and 50 until the correct positioning is achieved. In this position, the second clamping screw 37 is tightened.
  • the vector brush 20 thus assembled can now be inserted into the guide grooves 34, 35 of the carriage 9 from above and fixed at the desired height with the first clamping screw 36. This sets the distance from the air brush nozzle 55 to the film web to be labeled, which results in a larger or smaller spray cone.
  • the vector brush 20 is now ready for use.
  • the ink cartridge 26 ' can be fastened in the cassette 62 in a manner known per se, for example in the manner known from ink pens, namely in that the ink cartridge 26' is only automatically pierced by a mandrel and thus opened when it is inserted.
