Moreover, it is preferable that it is the intermittent exercise | movement which stops temporarily at each process.

  The receptacle 42 is a means for aligning and transporting the exterior material supplied from the exterior material supply device. In the present embodiment, the receiver 42 functions as a fitting type, corrects the bending of the exterior material, and ensures the engagement between the exterior material and the inner container. Therefore, the space in which the exterior material of the receptacle 42 is placed has substantially the same dimensions as the exterior material. Further, as shown in FIG. 1, the receivers 42 are arranged at equal intervals with respect to the traveling direction of the conveyor 41.

  Here, as shown in FIG. 2A, the receiving device 42 includes a pair of metal planes 421 arranged to face each other, and a plurality of metal partition members 423 interposed between the pair of planes. And a support piece 422 provided at the lower part of the plane.

The plane 421 is a member for forming a space for housing the exterior material by combining with a partition member 423 described later.
As shown in FIG.2 (b), the plane 421 has the support piece 422 in the lower part. More specifically, the planes 421 are arranged to face each other and are inclined inward (that is, in a direction approaching each other) from the top to the bottom. Note that the inclination angle of the flat surface 421 is substantially the same as the inclination angle of the wall surface of the exterior material S.

  The plane 421 may be made of a material having such a rigidity that it does not deform even when an external force is applied, and is made of, for example, stainless steel, iron, copper, aluminum, or the like. In this embodiment, a stainless steel metal plate having a smooth surface is cut out and bent to form a predetermined shape.

The support piece 422 is a member for preventing excessive fitting when the exterior material S is installed on the receiving tool.
As shown in FIG. 2 (a), the support piece 422 is provided substantially at the center of the lower portion of the plane in each space partitioned by a partition member to be described later.

As shown in FIG. 2A, the partition members 423 are arranged to face each other, and are welded and fixed to the plane 421 at the same height. Further, the plane 421 and the partition member 423 are installed so that the plane 421 and the partition member 423 form a right angle so as to have a rectangular shape in plan view (not shown). In this embodiment, a metal rod is used as the separating member 423, but the present invention is not limited to this, and a columnar member or a plate-shaped member may be used. Further, the separation member 423 may be in contact with a part or the entire surface of the exterior material S.

The guide member 43 is a member for preventing the composite container C from falling from the receiver 42 when the composite container C circulates in a state of being placed on the receiver 42.
As shown in FIG. 1, the guide member 43 is provided at the lower portion and the folded portion of the conveyor 41. The structure of the guide member 43 is not particularly limited as long as the container can be prevented from falling from the receiving member 42, and may be a flat plate or a rail shape corresponding to the production line. Moreover, when it is a plane board, it is good also as a mesh shape. Examples of the guide rail member include stainless steel, iron, copper, and aluminum.

  Moreover, it is preferable that the guide member 43 is provided with an interval that allows the composite container C to pass between the guide member 43 and the conveyor 41. If the distance from the conveyor 41 is too wide, the container may be caught between the conveyor 41 and the guide member 42 when the composite container C falls. On the other hand, if the distance from the conveyor 41 is too narrow, the circulation of the conveyor 41 may not proceed smoothly.

  Next, the operation of the composite container manufacturing apparatus 1 and the method for manufacturing the composite container C will be described with reference to the drawings as appropriate.

  First, the exterior material supply apparatus 10 inserts a nozzle into the exterior material S that is stacked with the opening portion facing downward. A suction part for sucking the exterior material is provided at the tip of the nozzle (not shown), and the exterior material S can be adsorbed by suction. Then, after the nozzle is lowered with the exterior material S adsorbed, it is inverted 180 degrees up and down with the horizontal axis as the base axis and placed on the receiving device 42 on the conveyor 41.

  Next, the exterior material S placed on the receiver 42 is pressed from above by a position correction tool (not shown) and pushed into the receiver 42. At this time, the support piece 422 can prevent the exterior material S from being pushed too much into the receiving member 42. And it is conveyed by the conveyor 41 to the lower part of the pasting apparatus 20. The pasting device 20 applies glue to the inner surface of the exterior material S that has been carried. In addition, in order to perform operation | movement reliably, the conveyor 41 is moving intermittently.

  Next, the glued exterior material S is conveyed to the lower part of the inner container supply device 30 by the conveyor 41. The inner container supply device 30 cuts out the inner containers one by one from the inner containers V stacked with the opening portion facing upward. On the other hand, the conveyed exterior material S is pushed up from below the receiving tool 42 by an exterior material push-up device (not shown) and combined with the cut out inner container V. The combined composite container C is placed on the receiver 42 again as the exterior material push-up device descends.

  The composite container C placed on the receiving tool 42 is pressed from above by the position correcting tool and pushed into the receiving tool 42. At this time, since the receiving member 42 is substantially the same as the dimension of the exterior material S, it functions as a fitting type. Thereby, the bending | flexion by the flap of the exterior material S etc. can be corrected, and fitting with the exterior material S and the inner container V can be performed reliably.

  The completed composite container C is then sent to the content filling process by a delivery cylinder (not shown). The composite container C filled with the contents is sealed with a shrink film or the like after the opening is sealed with an aluminum cap or the like.

  On the other hand, when a trouble occurs in the process after the completion of the composite container C, in the present invention, the completed composite container C can be circulated in a state of being held on the receiving device 42 of the transport line. For example, when an abnormality is found in the delivery cylinder that delivers the completed composite container C to the next process, the entire production line has been stopped in the past, but the conveyor 41 can continue to circulate in the present invention. Moreover, since the guide member 43 is provided in the transport line 40, it is possible to prevent the composite container C from falling off the receiving tool 42 when it circulates on the transport line.

  Furthermore, according to the present invention, when the production line stops at the stage of being glued, conventionally, the glued container has to be discarded. However, by providing an accumulation function in the transfer line 40, it is possible to perform the final process of manufacturing the composite container, and it is possible to reduce production loss. In addition, when the completed composite container C is circulated in a state of being held by the receiver 42, production can be resumed immediately when the problem is solved.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said Example. For example, as shown in FIG. 3, another conveyor may be provided between the composite container manufacturing apparatus and the next process. Thereby, a composite container can be accumulated on the newly provided conveyor. Further, by providing a newly provided conveyor across the floor, it is possible to efficiently produce even in a limited space.
