  • FIG. 10 shows a simplified embodiment of the variant shown in FIGS. 8-9, in that only the pair of rails 102 is used for the advance of the cans 2 and the pair of rails 101 is omitted. Instead of the non-existent pair of rails 101, a base plate 121 is required for supporting the can 2. As a result of the pair of conveyor rails provided only on one side, the can 2 only rests completely on the base plate 121 when the rails 102A and 102B are at the same height relative to the base 35. The surface 122 of the base plate 121 and the upper rail surfaces 123 of the two conveyor rails 102A and. 102B then lie in the same imaginary plane.
  • the can 2 is alternately by the rails 102A and. 102B raised and unrolled on the bottom edge 124 of the can 2 by the forward movement of these rails along the guardrail 3.

  • the distance Z is shorter than the distance between two Joints.
  • FIG. 11 shows the use of the device according to the arrangements shown in FIGS. 1 and 2, 6 and 7 and 8-10 as a can magazine 50 with an empty can station 51.
  • the can 2 is conveyed into the can magazine 50 in the direction shown by the arrow L into the empty can position P. From this position P, the can is cleared away in the direction of arrow M by means not belonging to the invention, for example a clearing arm (not shown) which detects the can 2.
  • FIGS. 6 and 7 are used to convey the can 2 in the can magazine 50 by means of the rails 6A and 6B, while in the area of the empty can magazine 51 the can 2, in the manner shown in solid lines, only with the rail 6B essentially in the direction L so long is promoted until the can 2 actuates an electrical proximity switch 52, which causes the rail movement to be interrupted.
  • the conveying can take place with the rails 6A and 6B, as indicated by dash-dotted lines, provided that an additional switching element which signals the same height of the rails (not shown) is combined with the proximity switch 52 such that after this proximity switch 52 responds, the rails are only stopped when the same height of the rails 6A and 6B is reached.
  • the rails are deeper than the base plate 5 (see FIG. 2), so that the can 2 can be cleared away in the M direction.
  • a base plate (not particularly shown) is provided only in the area of the empty can station 51.
  • This base plate essentially covers the width of the empty can magazine, i.e. extends, seen from point P in the direction of the can magazine 50, to an area limit of the empty can magazine 51 indicated by a broken line.
  • This base plate is arranged a few millimeters higher relative to the rails of the rail pairs 101 and 102 which are at the same height.
  • the rails of the pairs of rails 101 and 102 lift the can 2 alternately onto the base plate and against the proximity switch 52 when conveying into the empty can station.
  • a switching element (not shown) that signals the height of the rails is combined with the proximity switch 52 such that after the proximity switch responds, the rails only stop when the rails are at the same height.
  • the empty can station 51 and the can magazine 50 are of the same design, with the exception that the guardrail 3 does not extend into the area of the empty can station, which applies to all of the empty can stations described so far and below shown type applies.
  • FIG. 12 shows the use of the variant shown in FIG. 3 with a can magazine 54 and an empty can station 55.
  • the can magazine 54 at the end part 58 bordering the empty can station 55 has the additional features that the rail 6B has an offset 56 against the longitudinal axis X of the magazine, so as to be further below that with Rollers 36 (indicated by circles in FIG. 12) to grip cans 2A.
  • a guide plate 57 which is provided in the direction of the longitudinal axis X and is provided in front of this offset and extends as far as the end 59 of the rail 6B, in cooperation with the guide rail 3 leading the cans 2A opposite the guide plate 57, forces the rollers 36 to assume a position in which FIG of the 3 rollers 36 essentially rest on the guide plate 57 in order to be conveyed to the empty can position P in this position.
  • the rail 6A essentially ends in the area opposite the offset 56.
  • Fig. 12 four continuous can positions are shown, namely position K1, in which the can 24 is still in the can magazine 54, position K2, in which one of the rollers 36 on the guide plate 57 is in the region of the offset 56, position K3, in which two of the rollers 36 rest against the guide plate 57 and ultimately the position P.
  • position K1 and P In order to better identify the roller positions, they are shown hatched in positions K1 and P.
  • the rollers 36 which are arranged on the can 2A as an equilateral triangle, are forced into a position in which the height of the equilateral triangle is perpendicular to the conveying direction L.
  • the cans 2A are conveyed into the empty can station 55 in this position of the rollers 36 until they abut on the proximity switch 52 which is also used for this variant.
  • the proximity switch 52 immediately stops the rails 6A and 6B at any height.
  • a previously described combination of the proximity switch 52 with a means signaling the height of the rails is also possible if the rails are to be stopped in the area below the base plate.
  • the advantage of this variant is that the can 2A in the empty can station 55 then rests on the base plate 5 with all the rollers 36 after the proximity switch 52 has been reached.
  • the cans 2A are conveyed through the can magazine 54 with an undefined roller position.
