Definitions

  • the invention relates to a waste tray for letter punches made of flexible plastic with a base part, with side walls projecting essentially vertically on the base part and with at least one support dome protruding on the base part at a distance from the side walls towards the interior of the tub.
  • the waste tray which can be attached to the lower part of a letter punch, is intended for receiving the paper chips punched out during the punching process. It is detachably attached to the lower part of the punch so that it can be emptied from time to time. With its bottom part, the waste tray also serves as a footprint for the punch.
  • the support dome ensures that the waste tray, which is made of a soft plastic, is supported on the inside of the lower part and cannot bend.
  • the waste trays are usually made by injection molding. The waste trays have to be temporarily stored and correctly fed to an assembly station until they are installed on the lower part of the punch. Because of the problems encountered with the orientation of the punch lower parts, this was previously not possible fully automatically.
  • the object of the invention is to develop a waste tray which is easily stackable for intermediate storage and transport purposes.
  • the support dome has a cavity which extends through the base part and is open towards the outside of the base part. With the cavity, it is possible for the support dome of a waste tray to engage in the cavity of an adjacent waste tray when stacking waste trays, so that the waste trays can be stacked on top of one another in a defined orientation.
  • a preferred embodiment of the invention provides that the support dome essentially has the shape of a truncated cone, while the cavity forms an inner cone.
  • the support dome In order to enable a non-positive connection of the waste trays stacked one above the other, it is advantageous if the support dome also has a circumferential thickening near its tip. In order to ensure that the trays can be supported on the free edges of their side walls when stacked, it is important that the support dome is higher than the side walls.
  • a further securing of the position when stacking the waste trays is made possible by the fact that at least one locking element projects beyond the interior of the tray at a distance from the support dome and that in the area of the at least one locking element there is an opening on the bottom part in which the locking element of an adjacent waste tray can be locked.
  • an arrangement with several waste trays is expediently used, in which the waste trays are stacked on top of one another in such a way that their base surfaces rest on the upper edges of the adjacent side walls and that their support domes engage in the cavities of the adjacent support domes in a force-fitting manner.
  • the latching elements projecting inward engage from the outside in the openings in the adjacent waste trays.
  • Fig. 1 is a diagrammatic representation of a waste pan for one
  • FIG. 2a shows a plan view of the waste tub in the direction of the tub interior
  • Fig. 2b shows a section along the section line B-B of Fig. 2a;
  • FIG. 2c shows a section along the section line C-C of FIG. 2a
  • 2d shows a broad side view of the waste tub towards the outside of the tub
  • Fig. 3 is a side view of a stack of several trays.
  • the waste tray shown in the drawing is designed as an injection molded part made of a soft, flexible plastic. It is intended for receiving punched-out pieces of paper from a punch hole and can be fastened to a bottom punch part (not shown) for this purpose.
  • the waste trough 1 has a base part 10 and side walls 12 projecting substantially perpendicularly above the base part. It also contains a channel 14 for receiving a stop rail which extends through an opening 16 in one of the side walls 12 and two support domes 18 which protrude from the inside of the base part 10 at a distance from the side walls 12 and which are connected to one another by a connecting web 20 formed on the base part are.
  • the support domes 18 ensure that the waste tray can be supported on an inner surface of the lower part and therefore does not bend when pressed onto a surface.
  • the support domes 18 have a cavity 22 which extends through the base part 10 and is open towards the outside of the base part.
  • the cavities 22 each form an inner cone into which a support dome 18 of the shape of a truncated cone of an adjacent waste tray can be inserted for stacking purposes (FIG. 3).
  • the support domes 18 In order to obtain a non-positive connection between the waste trays 1 when stacked on top of one another, the support domes 18 have a circumferential thickening 24 in the vicinity of their tip.
  • the support domes 18 are somewhat higher than the adjacent side walls 12 (see FIGS. 2b and 3), so that the waste trays 1 stacked one above the other stand up with the lower edge of their base part 10 on the upper edge of the side walls 12 of the adjacent waste tray 1 (FIG. 3). .
  • two latching elements 26 projecting into the interior of the waste trough are additionally formed, which partially engage in the openings 28 on the bottom part side of an adjacent waste trough 1 when stacked on top of one another and can be latched onto the edge thereof.
  • the waste trays 1 can be stacked on top of one another in the correct position for the purposes of intermediate storage and transport.
  • the stacked waste trays 1 can be individually and fully automatically connected to an assembly station in which the letter punchers are installed and connected to the lower part of the punch.
  • the invention relates to a waste tray 1 for punchers made of flexible plastic, which is intended for receiving the paper chips punched out when punching paper.
  • the waste trough 1 has a base part 10 and side walls 12 projecting substantially perpendicularly over the base part 10.
  • support domes 18 are provided on the base part 10 at a distance from the side walls 12 toward the interior of the tub, which have a cavity 22 which extends through the base part 10 and is open towards the outside of the base part 10.

Abstract

L'invention concerne un réceptacle de papier découpé (1) pour perforateur, ledit réceptacle étant constitué d'une matière plastique flexible et servant à recueillir les parties de papier découpées lors de la perforation du papier. Ce réceptacle (1) présente une partie fond (10) ainsi que des parois latérales (12) faisant saillie par rapport à la partie fond (10) de manière sensiblement verticale. Des ergots de soutien (1) sont en outre situés sur la partie fond (10) à distance des parois latérales et dépassent de l'intérieur du réceptacle. Ces ergots de soutien (18) présentent une cavité (22) ménagée à travers la partie fond (10) et ouverte vers le côté extérieur de cette dernière (10). Ils permettent de positionner correctement plusieurs réceptacles (1) au moment de les empiler à des fins de transport, de stockage ou de montage.
