Definitions

  • This invention concerns improvements in devices for supporting conveyor bands, that is, bands or belts carrying a load which causes the band to deflect.
  • the invention is primarily intended for use with an endless band conveyor described and shown in A. K. McCombies United States application Serial No. 319,846, of even date.
  • an endless band conveyor whose operative length is extended, or shortened, according to the quantity of cigarettes included in a reservoir in which said band is located to support some of the cigarettes.
  • the operative length needs to be supported to take the weight of the cigarettes and, because this length changes, there are provided movable supports which are spring loaded to urge them beneath the edges of the operative length of the conveyor where support is necessary.
  • the band is supported within the reservoir on a roller and this roller is attached to a slide which moves to alter the operative length of the band and slides in slots in the sides of the reservoir.
  • This slide remote from said roller is shaped to engage the supports and push them aside as the operative length of the band extends, where- -after they spring inwards under spring pressure as the slide clears them and provide side supports for the band.
  • the other end of the slide is similarly shaped and so, as the operative length of the band is shortened, the supports are pushed outwards against the spring tension and snap inwards again after lthe slide has passed.
  • the present invention provides a better method of operating the supports, as they are positively moved inwards and outwards and the springs are eliminated.
  • a device for supporting a conveyor band in the manner outlined above, comprising a fixed rail at each side of the band and supports mounted on each rail and slidable thereon toward and away from the band, a slide carrying a roller around which the band turns lat the end of its operative length, and a guide rail at each side of the slide, said supports being shaped to embrace the guide rail which is bent at one end to constitute a cam adapted to move a support transversely of the xed rail as the slide moves.
  • the support may have a part shaped as a hook and adapted to slide over the xed rail on which it is held in place by friction, the grip of the hook-shaped part being suflicient to prevent accidental displacement of the support but offering little resistance to movement of the support by the guide rail.
  • the fixed rail may have two parallel grooves along it and the hook-shaped part of the support then has a protuberance adapted to snap into either groove ⁇ and hold the support in the desired position.
  • FIGURE l is a fragmentary side elevation of part of the apparatus described and shown in the United States application referred to above, showing the present invention applied thereto,
  • FIGURE 2 is a section of FIGURE 1 on the line 2 2,
  • FIGURE 3 is a plan of part of FIGURE 1, some parts being in section.
  • an endless band conveyor 144 turns round on a roller 145 which moves to and fro as described in the application referred to.
  • the roller spindle is supported in a slide 146, to which is xed a curved back pl-ate 147, and is pulled to the left in FIGURE l by a flexible cord 149 which may be pulled by a weight (not shown) as in the aforesaid application.
  • the band 144 is driven in the direction of the arrow A, FIGURE 1, by a pulley, as in the said application and if this pulley stops, because cigarettes are not to pass out of the reservoir, another pulley pays out more of the length of the band and the cord 149 pulls the back plate and slide to the left to increase the capacity of the reservoir.
  • the sides of the band are supported as in the application referred to by movable supports but these are constructed differently in the presentv case and bear the reference 162, and it is to these supports and their operation that the present invention is directed.
  • each side of the magazine is a fixed rail of rightangled section and it has two grooves 171 lengthwise of the horizontal web.
  • the supports 162 each have a hookshaped part 172 which embraces the horizontal web and can slide on the said web from an inner, or band supporting, position to an outer position, clear of the edges of the band, so that the slide 146 can pass them as the slide moves to and fro, the supports being moved for this purpose as described later.
  • the inner side of the free end of the hook has a small protuberance 173 which catches in the grooves in the web and locates the support in either position after it has been moved.
  • the supports are made of an elastic material, such as moulded plastic, so the free end of the hook can spring slightly to permit the protuberance to snap into land out of a groove.
  • the hook-shaped part of the sup-port merges into an upstanding web 172 at right angles to the plane of the inner faces of the hook and this web has two parallel extensions 17S at right angles thereto, the upper surface of the upper extension constituting the band supporting surface.
  • the lower surface of the lower extension 175 also engages the lower run of the band and supports it against upward movement but this is for a purpose not connected with the present invention.
  • short extensions 176 extend at right angles thereto and directed towards one another so that the upstanding web 174 and the several extensions define a loop of substantially rectangular shape with part of oneside open. This open part is the distance between the opposed edges of the short extensions and the distance between them is equal to the thickness of the slide.
  • the supports are moved in and out by cam rails 178, integral with the slide 146, and having their ends 179 which are near to the roller 145, bent inwards towards one another to provide cams.
  • the inner faces of the web 174 and the short extensions 176 are shaped to give a horizontal cross-section of double Wedge shape with an -apex at the mid-length of the web or extension.
  • the shape can be seen best in FIGURE 3 where the respective apices on the web 174 and an extension 176 are marked 177.
  • the supports 162 also provide a guide for the slide to move in, as the cam rails are part of t-he slide and the rectangular loop fits over a cam rail with .the shor-t extensions engaging the inner sides of the cam rail land their ends engaging the top and bottom surfaces of the slide.
  • the supports can grip the horizon-tal web of the fixed rail merely by friction between the hook-shaped part of a support and the rail but the grooved rail and the protuberance on the support gives a more reliable performance.
  • the back plate has a side wall 1-80 which is screwed to the back plate and can abe adjusted across the width thereof, to cater for cigarettes of different lengths.
  • 4In apparatus comprising a conveyor band for cigarettes and whose operative length is increased or decreased according to the quantity of cigarettes contained in a reservoir, in which said band is located to support said quantity, and having a slide carrying a roller around which the band turns to pr-ovide an upper cigarette supporting run and a lower return run, the slide being movable lto and fro to alter the operative length .of the band, means for supporting the supponting run of the band, against the Weight of the cigarettes, consisting of slidable supports and a xed rail on each side of the band, on which the supports can slide toward and away from the conveyor, and means for moving the supports inwards into a position where they move beneath the edges of the band to support nl. it, and outwards from said position and clear of the band, as the slide moves to and fro to alter the operative length of the band.
  • Band supporting means as claimed in claim 2 comprising a protuberance on each hook-shaped part and means for retaining the supports in position, after movement, consisting of grooves in the xed rails into which a -protuberance can enter.
  • Band supporting means a claimed inclaim 4, in which the loops of the supports each have part of one side open, and the ends of a loop dening said open part engage the top and bottom surfaces of the slide and provide a guide for the slide to move in.
