Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a transfer vehicle and a transfer path to a carton hopper in an automatic warehouse / factory, etc., especially in a factory where an automatic assembling / packing machine (cartner) is installed. The present invention relates to a device for delivering a returnable box to and from a starting end.

[Prior Art] Conventionally, it was generally thought that automation / unmanned operation in a packaging plant was limited to a case where a target to be handled was a standard (predetermined, limited shape range). For example, when handling an atypical object, that is, a set-up type packaging material such as a packaging box in a folded state before assembling, it is difficult to automate the operation of supplying the material to the cartoner. Therefore, in such a case, by increasing the holding capacity of the carton hopper for supplying the material to the cartoner as much as possible, the time interval for supplying the material to the carton hopper is extended to save labor. The supply of the material to the carton hopper is performed in units of boxes (carrying boxes) accommodating a large number of materials, and reciprocates between the carton hopper and the previous step by non-automatic work.

[Problems to be Solved by the Invention] In the above carton hopper, there is a problem that the supply time interval does not become so long because the capacity limit of the carton hopper is relatively small. Further, the returnable box must be reciprocated at least every time the carton hopper becomes empty, which is an obstacle to labor saving. The above problems can be solved by using a plurality of returnable boxes, and by constructing a device in which the next returnable box is always on standby and automatically supplied to the Cartner one after another. There are the following issues. Generally, the receiving place of the returnable box and the cartoner are often placed at the same level, and the carton hopper is often placed above the cartoner.Therefore, the transport path connecting them is usually an elevated road that allows passage of an operator or a service person. Need to be designed. Therefore, it is desirable that the starting end of the conveying path has both the function of receiving and the function of raising.

The present invention has been made to solve the above problems, and treats a setup type packaging material, which is a non-standard type, as if it were a standard type, lengthens the time interval for supplying the packaging material to the cartoner, and raises the overhead shape. It is an object of the present invention to provide a returnable box transfer device having the above configuration.

[Means for Solving the Problems] A returnable box transfer device according to the present invention receives a plurality of returnable boxes between an open top type transfer vehicle and an elevated transfer path leading to a carton hopper of an assembly / packing machine. The delivery device is characterized by including the following elements. Here, each element means (a) a receiving seat that can be approached by the carrying vehicle and has a height substantially the same as that of the carrying vehicle, and is provided so as to stand upright adjacent to the receiving seat. At least one ascending / descending vertical conveyor that forms the starting end of the road is installed, (b) Horizontal displacement is possible between the transfer vehicle and the receiving seat, and at least two vertical columns A skid provided with an open shelf that can be placed in combination with a plurality of tiers of carrying boxes, and that has a drawer-like open shelf, (c) A plurality of wrapping cables that are wound between the horizontal support shafts above and below the vertical conveyor. A plurality of step plates mounted on a belt or a chain at intervals corresponding to the intervals between open bottom plates of skids and capable of supporting the return box at both side edges of its bottom surface; (d) Opposite of the stationary holding table with respect to the vertical conveyor. Do you want to stand upright to the side? In the upright state, each of the step plates of the vertical conveyor is provided so as to be able to enter the space formed facing each other, and suction-bonded to each of the plurality of carrying boxes placed on the open shelf, A movable post provided with a suction means or a buffer pressing means for pulling this out and bringing it onto the step plate, or pushing the return box on the step plate into the open shelf, and (e) sequentially synchronizing the above means. It is a control means for operating / standby by operating.

[Operation] With the combination of the above means, it is possible to extend the supply time interval without being limited by the capacity of the carton hopper by handling the set-up packaging material which is an atypical product as if it was a standard product and transporting it. There is an action.

In addition, by having both the function of receiving and ascending at the beginning of the elevated transport path that connects the receiving place of the returnable box and the cartoner's carton hopper, it has the effect of promoting labor saving or unmanned operation of the packaging factory.
