Definitions

  • the invention relates to a workpiece carrier having a receiving region for receiving workpieces to be transported or stored and having a first region, by means of which the workpiece carrier is stackable with a workpiece carrier located above this and with a second region, by means of which the workpiece carrier with a lower thereunder Workpiece carrier is stackable.
  • workpiece carriers are used for receiving or transporting workpieces, for example from the automotive industry.
  • Known workpiece carriers have a receiving area for receiving the workpieces and a wall partially or completely surrounding them, the upper edge of which is flat and on which a workpiece carrier stacked above rests.
  • a disadvantage is that the walls of a workpiece carrier due to the weight of an overlying workpiece carrier can be pressed apart, which can cause a stacked workpiece carrier is no longer seated on the wall of the underlying workpiece carrier, but slipping into this which is undesirable is. This can cause the stack to become unstable, resulting in difficulties in transportation and storage.
  • first region or the second region of the workpiece carrier comprises a groove and the other of the regions has at least one projection which is designed such that it at least partially in the groove is receivable. It is conceivable, for example, that the workpiece carrier in its lower region and a projection and in its upper region has a groove, so that engages in the stacked state, the projection of an upper workpiece carrier in the groove of the workpiece carrier located below. This arrangement results in that even at high loads, d. H.
  • the workpiece carrier on a wall which surrounds the receiving area partially or completely and at the upper edge of the first region and at the lower edge of the second region is arranged.
  • the walls can completely surround the receiving area on four sides, for example. It is also conceivable deviating embodiments in which, for example, one side of the receiving area is open, ie only three walls are provided.
  • the projection of the wall extends obliquely, in such a way that it forms an acute angle with the plane formed by the wall.
  • the angle between the wall and the projection may be in the range of 10 ° to 50 ° and preferably in the range of 20 ° to 30 °.
  • the projection is made elongated and extends in the longitudinal direction parallel to the wall on which it is arranged.
  • the projection can thus be designed as a web, which can be carried out continuously or interrupted.
  • the groove may have an inner groove wall directed towards the receiving region and an outer groove wall facing away from the receiving region, which run parallel to the wall on which they are arranged.
  • said projection which may for example be embodied as a web, is received or clamped between these groove walls.
  • the inner groove wall has a lower height than the outer groove wall. It is conceivable that the projection and the groove are designed such that the projection rests in the inserted state on the inner Nutwandung above. It is also conceivable the case that between the projection and groove wall in the inserted state remains a distance, i. that the projection does not rest on the inner groove wall. In its end region, the projection may rest in the region of the groove in which the outer groove wall merges into the groove base.
  • the inner groove wall can be executed interrupted. Basically, of course, an embodiment is conceivable in which the inner groove wall is designed to run continuously.
  • outer groove wall and / or the projection can be carried out continuously or interrupted.
  • the groove has a groove bottom
  • the receiving area has a base in which one or more receptacles for workpieces are formed and that the groove base is parallel to the base.
  • the groove bottom can be designed such that it is not aligned with the wall, but is offset from this.
  • the groove base is preferably outwardly, d. H. facing away from the receiving area, offset from the wall.
  • the groove is used in this embodiment of the invention for receiving a likewise offset from the wall of the workpiece carrier projection.
  • the wall has rib-like regions which are spaced apart from one another for their stiffening. These can be opposite the base of the wall inwards, d. H. be directed to the receiving area or project outward.
  • the inner groove wall may extend from the rib-like regions of the walls or form their continuation.
  • the inner groove wall is provided only in the areas in which extend the rib-like areas.
  • the projection may be designed such that it connects the base of the receiving area with the wall of the workpiece carrier.
  • the projection is U-shaped, with a leg merges into the wall and the other leg in the base.
  • the workpiece carrier is made in one piece.
  • the workpiece carrier can consist of ABS (acrylonitrile-butadiene-styrene copolymer), polystyrene or mixtures of these materials or have these materials or mixtures thereof.
  • ABS acrylonitrile-butadiene-styrene copolymer
  • polystyrene or mixtures of these materials or have these materials or mixtures thereof.
  • other polymers such as polypropylene or polyethylene are used to obtain a better resistance to chemicals. The use of special materials is possible.
  • the workpiece carrier consists of a receiving area, which is partially or completely surrounded by walls 10 in its edge region, whose upper portion is shown in Fig. 1 in section.
  • the wall 10 extends vertically and merges in the region of its upper edge 12 into the groove 20.
  • the groove 20 is opposite to the Wall 10 offset to the outside, that is from the arranged in Fig. 1 left of the wall 10 receiving area a greater distance than the wall 10.
  • the groove 20 is formed by the inner groove wall 22, the outer groove wall 24 and the groove bottom 26, which connects the walls 22, 24 with each other. As can be seen from Fig. 1, the groove bottom 26 extends horizontally and perpendicular to the vertical wall 10 and to the groove walls 22, 24.
  • the inner groove wall 22 is aligned approximately with the wall 10 and with its outer side, whereas the outer groove wall 24 is arranged offset from the wall 10 of the workpiece carrier to the outside.
  • the groove 20 in its embodiment shown in Fig. 1 extends in the region of the upper edge 12 of all walls 10 of the workpiece carrier.
  • the groove 20 may be executed continuously or also have interruptions. It is conceivable, for example, that there is no groove in the corner regions of the workpiece carrier. These corner regions can, for example, run obliquely with respect to the adjacent walls 10 and serve as centering aids. In principle, however, it is also possible that the groove 20 is made continuous, d. H. extends over the entire upper edge of the walls 10 of the workpiece carrier.
  • Fig. 2 shows in section the lower edge 14 of the wall 10 and a portion of the base 40 with receptacle 50.
  • the receiving area of the workpiece carrier consists of the base 40, in which one or preferably a plurality of receptacles 50 are formed for receiving the workpieces.
  • a section U-shaped projection 30 which connects the wall 10 to the base 40 and which is designed as a web.
  • one leg of the U-shaped projection 30 in the wall 10 and the other leg in the base 40 via.
  • the projection 30 is arranged obliquely relative to the wall 10, so that there is an acute angle between the plane formed by the wall 10 and the projection 30. From Fig. 2 further shows that the projection also extends at an acute angle to the plane formed by the base 40.
  • the projection 30 is opposite the wall 10 laterally and opposite the base 40 offset down and thus forms a relation to the wall 10 and the base 40 projecting portion of the workpiece carrier. In the embodiment shown in FIG. 2, the end region of the projection 30 is approximately in the plane formed by the receptacle 50.
  • the projection 30 shown on the right in FIG. 2 is received in the groove 20 shown in FIG. It remains between the lower, merging into the base 40 legs of the projection 30 and the upper edge of the inner groove wall 22 a distance, as can be seen from Fig. 4, which shows two identical workpiece carrier in stacked state.
  • projection and groove wall are arranged or designed such that the projection rests on the inner groove wall.
  • the end portion of the projection 30 bears on the one hand on the inside of the groove wall 24 and the other on the groove bottom 26 at. In particular, at higher loads, the projection 30 is pressed into the groove 20, whereby the groove and the projection are fixed. In this way it is ensured that there is a high stability of the stacked workpiece carrier.
  • the outer groove 24 is made continuous, whereas the inner groove 22 is disposed only in the areas in which the wall 10 reinforcing ribs 16 has. These are pulled inwards in the embodiment shown in FIG. 3 and continue upward in the form of the inner groove wall 22.
  • the inner groove wall 22 may extend over the entire width of the ribs 16 or only over a partial region thereof.
  • the structure and the arrangement of the groove with groove walls and the projection can be identical over the entire circumference of the workpiece carrier, as shown in FIG. 4 can be seen.
  • deviating implementation forms for example a continuous inner groove wall 22 or a broken outer groove wall 24 are also conceivable.
  • the structure and the arrangement of the groove with groove walls and the projection can be identical over the entire circumference of the workpiece carrier, as shown in FIG. 4 can be seen.
  • the material thickness of the workpiece carrier can be identical in all areas or can be chosen differently. Depending on the area of application and the size of the workpiece carrier, thicknesses of the order of 4 mm to 10 mm are conceivable. Also above or below lying material thicknesses are feasible.
  • the workpiece carrier consists for example of ABS (acrylonitrile-butadiene-styrene copolymer) or of electrically conductive polystyrene.
  • ABS acrylonitrile-butadiene-styrene copolymer
  • electrically conductive polystyrene electrically conductive polystyrene.
  • PP / PE special materials is also possible. It is also possible to use mixtures of these materials.
