SE504877C2 - Device for painting slender objects with rectangular cross-section, e.g. wood planks, and comprises box - Google Patents

Abstract

All constituents (2-8) are fixed in the box (1) so that the item to be painted is manually pushed through the device in one operation, and painted on three or its four sides (both edges and the upper side). The box simultaneously functions both as a container for the paint and as a chassis, in which all other constituents are fastened. All constituents (2-4,7) which come into contact with the paint are located within a volume defined by the box, where the open upper side of the box is considered to be covered with a flat plate, parallel with the box base, located at a maximum of 30mm above the box upper edge. The flat short sides are taken to reach even up to the flat plate. All excess paint rubbed off by the corresponding rollers (4) and brush (7) is delivered back into the box for further use in the painting work.

In order to be able to handle different plank widths, the "kantrol1rama" has been made Adjustable sideways. This is achieved by the "edge rollers" being attached to a bracket via threaded U-brackets. The bracket has a number of pre-drilled holes for alternative widths. As a result, three sides are coated with paint. In order for the result to be good, however, it is required that all excess paint is removed from the detail. This is to avoid paint dripping during the later handling and drying of the painted planks. The excess paint from the edges is removed as the part passes two more rollers inclined in the vertical plane. The inclination of these rollers is so great that when the part passes these, the force component which wants to rotate the roller becomes so small that no rotation occurs. If rotation were to occur, the parting effect would be significantly reduced. The reason why rollers are still used is that you can manually rotate the rollers and thus ensure that the roller surface that comes into contact with the next plank to be painted is as fi ash as possible and in this way obtain a good smoothing effect. These wiping rollers are attached to the same bracket and in the same U-bracket as the previously mentioned edge rollers. This means that the wiping rollers are adjustable sideways in the same way as the edge rollers. x In the last step, the excess ropes are removed from the top. This takes place when the part passes just before the machine's outlet between a horizontally placed brush and a support shaft identical to the one in the inlet. In order for the erasing effect to be satisfactory, it is necessary to use a relatively long-haired brush with stiff edges. This is because the top is generally unplaned unlike the edges that are planed. The bristles of the brush "seek" into the unevenness of the unplaned surface. The excess paint that is ironed off the edges and top ends up in the container and can be reused for further painting.

Claims (3)

504 877 Claims 1. Device for coating, with liquid material eg paint, of slender details with a rectangular cross-sectional shape, eg wooden planks, comprising a box (1), 3 coating rollers (2) and (3), 2 pcs wiping rollers (4), 2 impeller-equipped and fi spring-loaded support shafts (5), a fastening bracket (6), a wiping brush (7) and 4 pcs springs with adjusting screw (8) whereby the details (2) - (8) are attached to the box ( 1) in such a way that when the part to be coated, by hand, is passed through the device once, is coated on three of its four sides (both edges and the top), characterized in that the box (1) simultaneously functions both as a container for the coating material and as a chassis (carrier, bracket) in which all other components (2) - (8) are attached. Device according to claim 1, characterized in that all details (2) - (4), (7) which come into contact with the coating material are located within a volume defined by the box (1) when the open top of the box is intended to be covered with a flat disc, parallel to the bottom of the box (1), located a maximum of 30 mm above the upper edge of the box (1). In addition, the flat short sides should be expected to reach all the way up to the intended flat disc. Device according to claim 1, characterized in that all excess coating material which is ironed off the part, at (4) and (7), returns to the box (1) for further use in the coating work. Device according to claim 1, characterized in that the removal of the excess coating material on the upper side of the part takes place with a brush (7) along the entire width of the part. Device according to claim 1, characterized in that both edges of the part are coated with rollers inclined in the vertical plane (3). Device according to claim 1, characterized in that the excess coating material on both edges of the part is ironed off with rollers inclined in the vertical plane (4). Device according to Claim 1, characterized in that the pressure between the part and the rollers (2) and between the part and the wiping brush (7) is adjustable in that the support shafts (5) are loaded by a prestressed spring (8). The spring bias, and thus the pressure, is adjustable via adjusting screw (8). See figure 504 877 Device according to claim 1, characterized in that the brush (7) is fixed in the box (1) by passing two screws through two holes in the brush (7) and passing the threaded part of the screw through holes in the box (1). and fastened with a nut on the outside. The required distance between the brush (7) and the drawer wall is ensured by placing spacer sleeves between the brush and the drawer wall. Se fi gur 3.
