Definitions
- the invention relates to a device for applying a substance to a web by means of a magnetically pressed squeegee, wherein a supporting beam parallel to the squeegee carries axial limiting parts for the squeegee in the form of end plates extending normal to the supporting bar, and that the connection between the supporting bar and the end plate is actuated a handle is detachable.
- the advantage of the magnetic pressure of the doctor blade lies primarily in the fact that the pressure force of the doctor blade does not have to be introduced into it via lateral bearings, so that the doctor blade does not bend. Nevertheless, limiting parts for their movement make sense even when the doctor is pressed magnetically.
- Lateral end plates which usually serve at the same time to delimit the ink sump, can cooperate, for example, with a magnetically pressed doctor blade, in that they position a doctor blade roller exactly normal to the web direction by means of inclined surfaces.
- the squeegee rollers can be loosely guided in end plates arranged on the side of the support bar, so that they can be easily removed from the template after the application process has ended.
- Thin rollers are guided directly in a hole in the end plates that is open at the bottom, thicker rollers are provided with side journals, which are undercut by the end plates.
- magnetically pressed doctor blades can also be guided in vertical guide grooves of the end plates, with either the cross section of the doctor blade as such fitting into the guide groove or the doctor blade being provided with lateral guide pins.
- the variety of possible end plates is further increased by the fact that these can optionally also be magnetically attractable or displaceable in the vertical direction.
- a device has become known from WO88 / 09725 in which the end plates are pulled off the side of the carrying bar after loosening two screws (handles).
- the carrying bar does not have to be replaced as a result.
- a disadvantage of the known device is that a lateral removal of the end plates presupposes that the ends of the support bar are free.
- the invention provides a possibility of quickly and perpendicularly pulling off the end plates perpendicular to the direction of the support beam even when the support beam is installed.
- a pin is provided on the end plate, which can be pulled against the force of a spring by means of the handle from a slot into which a protruding from the support bar, parallel to the support bar, which is penetrated by the pin, can be inserted.
- doctoring devices with doctoring rollers which are cone-shaped at the ends and are connected to the end plates in such a way that the doctoring roller does not have any of the possible spatial arrangements of the doctoring device, that is to say neither in the installed state nor when or dismantling or transport, can be involuntarily separated from the support beam.
- the pin-shaped end of the roller doctor engages in a cage adjoining the end plate and is held in this by a cage cover, which in turn is held in place by a plug pin on the End plate is secured.
- the interchangeability of the end plate itself allows the doctor blade in one To store recess of the end plate, as is known per se from DE-U-87 13 787. Since the end plates are not easily removable there, however, horizontal slots have to be connected to the recesses which receive the end pins of the doctor blade, through which the bearing pins of the doctor roller are guided during insertion. In operation, the bearing journals are located lower than these lateral slots, so that there is no fear of the roller doctor being inadvertently lost. When the roller doctor device is rotated around the spar that carries the end plates, the doctor roller can fall out of the holder and thereby damage the surrounding circular templates. This possibility also exists when the roller doctor device is inserted and when it is removed, so that there are concerns in the known device against handling the roller doctor device together with the doctor roller.
- FIG. 1 is a view of a support beam with an end plate attached thereto
- FIG. 2 shows the inside view of the end plate from FIG. 1
- FIG. 3 shows a horizontal section through the recess 3 in FIG. 1
- FIG. 4 shows the assembly of the device according to FIG . 1.
- the device shown in Fig. 1 is used to apply a substance to a base 7 by means of a doctor roller 1, which is arranged by a magnet, not shown, arranged below the base 7 is attracted.
- a doctor roller 1 which is arranged by a magnet, not shown, arranged below the base 7 is attracted.
- Such devices are known and are not described in detail here.
- the end plates 4 which not only form a side boundary for the substance to be applied, but also allow the exact alignment of the doctor roller 1 normal to the direction of movement of the base 7 due to the inclined surfaces 6 at the bottom of the recess 3.
- the end plates 4 allow the squeegee roller 1, which is loosely guided in the recess 3, to be lifted out together with the carrying spar 9 after the machining process has ended, or to pivot it.
- the length of the doctor roller 1 and the pin 2 and the recesses 3 for the pin 2 are dimensioned so that the doctor roller 1 can not fall out of the recesses 3 in any position.
- the end plate 4 can be displaced vertically in relation to the support bar 9 between a sheet metal 10 running vertically in the machining direction and a guide plate 11 and can be detached from the support bar 9 by means of the handle 12.
- the end plate 4 has a slot 13, which is penetrated by a pin 14. This pin can be retracted against the force of a spring 17, which is supported on the one hand on a fixed plug 18 and on the other hand on a movable disk 19. This is the end plate 4 easily detachable by means of the handle 12.
- the end plate 4 carrying the doctor roller 1 is pushed onto the fastening plate 15 in the direction thereof until the pin 14 penetrates the opening 16 in the fastening plate 15. Since this opening 16 only loosely surrounds the pin 14, there is a certain vertical mobility for the end plate. In the lateral direction, this is secured by the plate 10 and by the guide plate 11 on the mounting plate 15. A magnetizable plate on the outside of the end part 4 allows it to be pressed against the base 7.
