Definitions

  • the invention relates to a device for cleaning grinding elements and the like formwork parts, with at least two pairs of conveyor rollers arranged transversely to the direction of flow, one of which is provided adjustable against the other, and with cleaning elements for the underside and the longitudinal edges.
  • Devices of this type are known in various forms, for example from AT-PS 242 347.
  • the device shown there is specially designed for cleaning formwork panels, formwork boards and the like, wherein between the two pairs of conveyor rollers, two sheet-shaped scrapers offset in the direction of travel to one another on the bottom and top and furthermore on the opposite side on the one side and fixed on the device other side scraper adjustable across the direction of flow are attached to scrape the side plate edges.
  • These scrapers are usually formed by individual scraper blades which, in deviation from a transverse plane to the conveying direction, are slightly inclined in this direction.
  • the conveyor rollers are designed there as crusher rollers, which break up the concrete crust adhering to both sides of the formwork panels to be passed through, in order to make scraping easier. While the upper conveyor rollers are adjusted by hand, the adjustable side scraper is controlled by a feeler lever, which rests on a side surface of the continuous formwork panel under spring load.
  • formwork technology has been largely determined by the use of so-called “formwork elements”, the rear part of which is formed by a lattice structure made up of individual sheet metal webs which are arranged transversely to the element level and welded to one another, and a formwork panel, for example the conventional one, can be exchanged on the inside that comes into contact with the concrete Type carries, the edge of which is surrounded by the frame of the support grid.
  • the invention therefore pursues the task of cleaning these end faces as completely as possible by machine, at least for thick formwork elements.
  • a cleaning device for cleaning at least one end face of a formwork element is arranged between two pairs of conveyor rollers, with an end face cleaner which can be moved through the path of the formwork elements in a conveying pause transversely to the conveying direction.
  • This end face cleaner can be designed in a conventional manner as a scraper, milling cutter or the like, but should in any case be such that the end face of a relatively thick formwork element is properly cleaned after one or two cleaning operations.
  • the formwork elements therefore have to be conveyed in cycles, while conventional thin formwork panels, which generally do not require a separate end face cleaning, can pass through in the conventional manner without stopping, as can individual formwork boards.
  • a common end face cleaner is expediently used for the front and rear end faces of the formwork elements.
  • it can have a sandwich scraping block made of scraping sheets and interposed plates made of plastic which can be deformed at least to a limited extent in a rubber-like manner. Both ends of each scraper blade thus form at least * scraper edge and are referred to below as the cleaning surface. Since these protruding ends can also deform separately, several scraping edges can be brought into engagement on each side.
  • a reciprocating movement of the end face cleaner on the same end face executes two oppositely directed scraping operations, which practically always achieves an adequate degree of cleaning. *a
  • the vertical and approximately parallel to the conveying direction of the shuttering elements arranged scraping block about a vertical axis over a few angles is held so that it can be pivoted to a limited extent Reduce the angle of attack, reduce the contact forces and increase the available spring action.
  • At least one sensing device is provided for palpating the end face of a formwork sheet in the area of a cleaning transverse plane. This or each sensing device can be switched off separately and the trigger of a sequence control for stopping the conveyor rollers, performing an end face cleaning process and switching the conveyor drive on again.
  • (1) denotes a machine frame which is designed as a trailer vehicle with rubber tires (2) and a drawbar (not shown) or which is fixedly movable on feet or small lockable castors.
  • an inlet boom (3) * with rollers (4) is attached on the right in FIG. 1. Both booms can be removed for road transport.
  • the lateral rollers (4) determine a guide track (19) of variable width and height with lateral guide rollers (18). * and on the left an outlet boom (5) Symmetrical to a central plane (6) of the machine frame, two conveyor rollers (8, 9) associated with the same support plane (7) as the rollers (4) are stored in the machine frame.
  • Two upper conveyor rollers (10, 11) are mounted vertically above this in a lifting frame (12) which is guided at its corners in vertical profile bars (13) and is arranged vertically adjustable parallel to itself by means of four threaded spindles (14) arranged close to them.
  • the spindles (14) carry chain wheels (15), which are enclosed and truncated by a chain (16).
  • the frame (12) can therefore be adjusted with the conveyor rollers (10, 11) using a single hand crank (17). All conveyor rollers (8-11) remain connected to a common conveyor motor by a common drive chain.
  • the bearing blocks (21) of the upper conveyor rollers (10, 11) sit in vertical guides (22) and are pressed down by compression springs (23) up to a stop bar (24).
  • Numeral (26) denotes a formwork element, the underside (27) of which is the formwork skin level forms by means of an embedded formwork panel (28), but otherwise has a latticework (29) of intersecting webs, the edge webs of which also encompass the edge of the interchangeably attached formwork panel (28).
  • This cleaning device comprises a guide bar (41) drawn into the lifting frame (12) parallel to the conveyor rollers, on which a tool slide (43) is guided by means of rollers (42), which carries the end face cleaner (37) on its underside and is driven by a geared motor ( 44) is adjusted via a chain loop (45).
  • a projection (46) attached to the slide (43) serves to actuate two limit switches (47, 48). Normally, the carriage (43) is at the top in FIG. 2 after the limit switch (47) serving as an off switch has been actuated.
  • the limit switch (48) controls the reversal of movement of the geared motor (44). After triggering an end face cleaning, the front end face (38) is cleaned by two scraping operations carried out in different directions.
  • a button switch in the form of a light barrier (51) with a transmitter and receiver mounted in the same housing is used to initiate a cleaning process.
  • arranged reflector (50) interacts.
  • the scanning plane (52) is arranged at a short distance from the cleaning plane in the direction of passage, in which the end face (38) according to FIG. 3 is located. This end face therefore always comes to a stop with a slight deviation after the light barrier has sensed the front end of the formwork element (26), has interrupted the drive of the conveyor rollers (8 to 11), which is expediently provided with a brake, and has shut the rollers down.
  • the geared motor (44) is switched on and moves the tool slide (43) with a first cleaning surface (56) of the end surface cleaner (37) from the limit switch (47) to the limit switch (48) and back in two scraping processes over the end surface (38) .
  • the drive for the conveyor rollers (8) is then switched on again and the formwork element (26) is transported on from the position shown.
  • the transport switch position is maintained once by the switch-on position of the light barrier (51) and also by the switch-on position of a second light barrier (53), the sensing plane (54) of which is in turn in the transport direction just before the plane in which the rear end face is located (55) of the formwork element comes to a standstill and can then be processed by the second cleaning surface (57) of the end face cleaner (37).
  • the gear motor (44) is switched on again when the return switch (47) is actuated and the drive of the conveyor rollers is started.
  • the formwork element (26) is conveyed further out of the second stop position 26 'drawn with dash-dot lines and then impregnated by means of a lower foam roller (61) immersed in an impregnating agent bath (60) and a side-mounted foam roller (62) mounted on the frame, and one of these opposing arranged adjustable foam roller (63). Shortly before the foam roller (62) is attached to the side surface (64) of the formwork element fixed to the frame side scraper (65).
  • a movable side scraper (66) is mounted with the roller (63) on a common support (67) which can be adjusted transversely to the conveying direction (30) by means of a spindle (68) with a hand crank (69).
  • (70) denotes a surface scraper lying on the underside (27), which has a rubber-like soft lip (72) for stripping off the previously applied impregnating or separating agent (60).
  • the opening width between the conveyor rollers (8 to 11) and the opening width between the side scrapers (65, 66) is first of all adjusted according to an inserted pattern of the formwork part to be cleaned by means of the crank (17). and the foam rollers (62, 63) are adjusted.
  • the desired mode of operation, with or without end face cleaning, is then preselected by a switch actuation, and the formwork element or other formwork part only needs to be placed on the rollers of the inlet-side bracket (3).
  • the entire further cleaning process runs automatically after switching on the drive of the conveyor rollers (8 to 11). Only if conventional formwork panels should be cleaned on both sides, they can be run through again after turning.
  • 3 and 4 is designed as a scraper block (85) with four scraper blades (81) and two outer cover sheets (82) made of spring steel, which are glued to intermediate damping plates (83) made of at least weakly elastic, damping material and from three holes (84) are penetrated.
  • the ends (85) and (87) of the scraper blades (81) protrude on both sides from the square-shaped base body, the actual scraper block, which is determined by the dimensions of the parts (82) and (83), and can thus differ during the scraping process, such as is shown with the blade ends (87),. individually bend and separately brought under spring load to the respective end face (38) or (55) and scrape them off.
  • FIGS. 5 and 6 Another possibility is a swivel mounting, as shown for example in FIGS. 5 and 6.
  • the scraping block (85) is designed and held in practically the same way as with the fixed clamping on the tool slide (43).
  • the holder is formed here by a swivel body (88) which can be swiveled about a vertical axis (73) in a rotary bearing (89) is mounted on the underside of the tool carriage (43) in a tilt-proof manner.
  • the swivel path is limited in both directions by stop pins (90). From the middle position shown, the cleaning tool can thus be pivoted through an angle of approximately 3 to 8 ° in order to use the cleaning surfaces (56) or (57) more uniformly.
