Equipment for the treatment of returnable packaging and the method of treatment of the returnable packaging 5

The invention relates to a method and apparatus for the treatment of return packages such as bottles and / or cans.

10

Stabilizers used for receiving return packages, for example in connection with return vending machines, are known in the art. For example, FI patent 98,895 discloses a stabilizer structure in which the stabilizer comprises a roller receiving roll, into which the rollback roll is fed and transported with the rotated roller 15 to a bottle identification station past a barcode scanner or a rollback camera reading camera. We refer to FI (P) 102,595.

Known hardware solutions still have the disadvantage of having the recovery kit upright: Y; staying. When the recovery package is inserted into the receiving roll 20 of the bottle feeding roll and is further moved away from the roll, the recovery package causes harmful inertia forces, for example, when the recovery bottle is fed to the top of the belt: · ·.

• · · This application presents a completely new type of device solution that is suitable for: 25 return packages such as bottle stabilizer as well as a device solution that *. · · Can sort the returned bottle into a desired position or is a device solution to crush / crush the return package. : volume. In this case, the device destroys the barcode when crushed and so-called.

: The use of a deposit system is possible. Once the deposit has been returned, the same 30 packs will no longer be eligible for a deposit because the bar code has been rendered illegible in the press.

The application discloses a novel type of device solution comprising a bottle receiving structure having a first gripping portion and a second gripping portion, at least one of which is movable relative to the second gripping portion. The recovery package 5 can thus be grasped by means of said gripping parts. Once the recovery kit has been gripped, the entire gripper is rotated so that, for example, the recovery kit is moved, after a rotation movement of 180 °, to a precise position on the post-gripper belt. The strap can be triggered and guided as a function of feeding the recovery kit onto the strap. According to the invention, it is most preferred to use a gripper comprising a first gripping section and a second gripping section, preferably vertically elongated structures and having a curved surface in contact with each other, the curved surface of each gripping portion forming a receiving space for the return package. When the recovery kit is positioned in the inlet space between the gripping portions in a somewhat semicircular space, the gripper gripping portion and / or gripping portions 15 are moved so that the receiving space is closed and the gripping portions engage with the recovery package from its side.

After infection, the entire gripper can be rotated as desired; : a) In the first preferred embodiment of the invention, the gripper serves as a: / ·· 20 stabilizer only, whereby the gripper is used to transfer the return package such as a bottle or can to the conveyor on the other side of the gripper, preferably • <| V 'for belt conveyor. The gripping parts / gripping portion are used on the belt conveyor. * I * · * V · after moving in the opposite direction, whereby the recovery kit is released from the grip of the gripping portions of the gripper at the desired step and / or at the desired speed.

(B) In another preferred embodiment of the invention, the gripper is used to move the return package such as a bottle or can to the scanner onto a preferably rotated:. * ·· disk, rotating the gripper 90 ° and after reading the barcode. Transfer the return packaging, such as a bottle or can, to the storage site, or:. j on top of the conveyor belt or in connection with a separate press or returned to the inlet, •: ·: 30 if packaging is not approved.

C) In a third preferred embodiment of the invention, the apparatus is used such that, for example, after the bar code has been read when the gripper has been rotated about. 180 °, the gripper gripping portions are used such that the space between the gripping portions is further closed and the gripping portionZ portions crush the recovery package, such as can 5, after which a crushed recovery package such as can can be released over the belt conveyor or warehouse.

The barcode reading can take place in the device according to the invention using a separate barcode reading station 10, in which the recovery package is rotated by a separate motor over the rotation plate, after which the recovery package has been released from the grip of the plate. After reading the barcode, grab the recovery package again and move the recovery package forward, for example, in the case of an approved can, compressing the recovery canister to a smaller volume, or transferring it to a separate storage or specific position on the belt conveyor or belt conveyor. There are many variations. If the return package at the input station A is not approved by weight or material identification, for example, at the input station Y: the gripper is not used and the return package is not moved forward. If the compression is not accepted after the bar code number, \: 20, the device can be used to move the recovery package back to the '' m: receiving position by rotating the gripper either in the opposite direction or in the same · ', ·' direction.

When used as a gripping structure with a gripper which is also carried by the gripping parts, the V * 25 return package, such as a can, a compression and / or a crushing movement, then acts as a gripper. The gripping portions are then preferably shaped such that: they overlap, at least in part, in a compression stroke, whereby a return package such as a 't' can is obtained to a minimum volume which is advantageous for storage.
