Definitions

  • TITLE IMPROVED LOCKING SYSTEM FOR SKIRT BOARD FOR BELT CONVEYOR SYSTEM.
  • This invention relates to improved locking system for skirt board for belt conveyor system.
  • BACKGROUND AND PRIOR ART It is already known to use skirt boards in belt conveyor systems and several constructions are in use.
  • skirt boards are used in conjunction with backing plates.
  • each skirt board is vertically pulled down on the backing plate by use of dove tail joints and the skirt board are locked through locking plates.
  • This arrangement is accompanied by a number of drawbacks and every operation and replacement requires complicated vertical inter dependent movements of the skirt board. Moreover it is time consuming and labour oriented.
  • a novel locking system for skirt boards comprising a serrated clamp plate held tight or locked on a rubber block with grooves supported on a backing plate with guide member for holding the rubber block characterized in that there is provided an elongated extension member on the backing plate extending through suitable slots/ holes in the rubber block and/ or serrated clamp, the free end of the extension member being provided with a locking cam mounted using holding means such as herein described.
  • the cam is mounted through the help of a pin to lie on the outer surface of the serrated clamp plate and is held in position using preferably circlips and the cam is a double cam jointed at the bases by a flat plate member.
  • the cam surfaces have suitable holes for mounting the same on the extension member.
  • the flat piece has a hole for insertion of a handle to operate the cam and the cam has the necessary profiles, which are identical on both the cam surfaces.
  • the member protruding/ extending from the backing plate is preferably a hollow square tube held to the backing plate by any suitable way such as welding, screwing etc.
  • Figure 1 shows a perspective view of an existing locking system.
  • Figure 2 shows a side view of an existing locking system.
  • Figure 3 shows a perspective view of the modified locking system without the cam unit mounted thereon.
  • Figure 4 shows a view of the modified locking system.
  • Figure 5 shows a side view of the modified system in the unlocked position.
  • Figure 6 shows the side view of the modified locking system in the locked position.
  • Figure 7 shows the modified locking system without the handle.
  • Figure 8 shows a plan view of a pair of the modified locking system, which is a part view of a belt conveyor.
  • Figure 9 shows a side view of Figure 8 and
  • Figure 10 shows a cam in perspective view as a unitary piece.
  • the complete locking system comprises essentially the support/ backing plate 1 , the rubber pad 2 and the locking plate 3 in both the existing and the modified locking systems.
  • the rubber pad has the usual channel 2A, which is engaged by the protruding member 1 A on the backing plate.
  • the rubber pad is clamped on the backing plate by means of a bolt 4 in the conventional system for which the backing plate has necessary threadings and the rubber pad has the necessary hole.
  • a short rod or hollow tube protruding member 5 fixed on the backing plate This can be fixed by welding or by other known mans.
  • This tube is shown to have a square cross section for ease of operation though other shapes are possible.
  • the rubber pad and the locking plate have suitable provisions like openings for mounting on the short tube member. This tube protrudes or extends a short distance outside the locking plate.
  • a horizontal through hole 6 at the front end of the member 5.
  • a double cam 7 with necessary mounting holes on the two of its legs 7A and 7B.
  • the two legs of the cam are (joined by a flat portion 7D) also provided with necessary holes or openings on the two heads for passing a holding member 7C.
  • the holes 7C in the flat member 7D and the holes 7E and 7F in the two cam pieces are of the same diameter as the cam.
  • the cam is mounted through a mounting pin 7C with the protruding member 5 occupying the inter space between the cam members.
  • Both the cams and the flat piece are integrally formed by casting.
  • Each cam head and the tail are identical in shape, configuration and dimensions.
  • Each cam has identical profile made of 3 faces a, b and c.
  • the face a has a straight face while face b is a cam profile face and face c is also a straight face.
  • the extreme end of the member 5 being a hollow member has an opening 5A.
  • the cam mounting holes 7A and 7B are provided at a short distance away from the extreme/ free end of the tube member. As shown in Figure 5, a small rod or handle is used which is inserted into the opening at the free end of the member 5 and by rotating the cam in anti-clockwise direction the clamping plate is in the unlocked position. The rubber pad can simply be hammered up or down as required.
  • a bolt and nut combination can be used or a split pin can be used. It is also possible to use two half pieces to be inserted from either side of the cam end, both having heads preferably hexagonal and one piece having an externally threaded end while other piece has matching internal thread provisions for engaging the external threads on the other piece. These two pieces can be of convenient dimension .
  • the locking plate has a hollow tube or protruding member extending from the front face of the backing plate.
  • a square rod This can be welded or mounted permanently in any suitable manner.
  • a hinged cam member is shown assembled with the help of a pin and kept in place using locking circlips.
  • Other holding means such as split pins, bolt and nut, snap fitting rods, a long bolt and a long hollow threaded rod etc. can be used.
  • a plate with a hole On the top of the cam, a plate with a hole has been provided.
  • the locking and unlocking can be done by rotating cam with the help of the rod.
  • the profile of the cam facilitates to press the serrated clamp against the rubber block when it is rotated downward and pressure can be released when the cam is rotated upward.
  • the time taken to rotate the cam from looking to unlock position and vice-versa is almost 25% of the time taken compared to the existing design.

Abstract

La présente invention concerne un nouveau système de blocage destiné aux ridelles de guidage qui comprend une plaque pinceuse dentelée (7) retenue solidement ou bien bloquée sur un bloc de caoutchouc à rainures supporté sur une plaque de support comprenant un élément de guidage pour retenir le bloc de caoutchouc. Cette invention se caractérise en ce qu'il est prévu un élément extenseur allongé (5) sur la plaque de support qui s'étend dans des fentes/trous appropriés formés dans le bloc de caoutchouc et/ou dans la pince dentelée, l'extrémité libre (6) de l'élément extenseur étant pourvue d'une came de verrouillage installée avec un moyen de support tel que celui selon la présente invention.
