BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for intermittently feeding a box or the like when storing the tube or the like in a box having a partition.

[0002]

2. Description of the Related Art A tube for filling toothpaste or the like is discharged from a production line and supplied to a filling line in a state where its spout is closed with a cap and its rear part is opened.

In order to transport the tubes from the production line to the filling line, a box in which a large number of tube storage chambers are formed by grid-like partitions is used. That is, the tubes coming out of the manufacturing line are inserted into the tube storage chambers one by one with their orientations aligned, covered, and then transported to the filling line.

Since the tube storage chamber of the box is extremely narrow and the partition can be moved with respect to the box body, conventionally, the tubes are packed by hand, and when the tubes are inserted into the tube storage chambers, The partition and the box body are not damaged.

[0005]

However, there is a problem that the above-mentioned conventional manual tube packing work is time consuming, inefficient, and both the production line and the filling line are hindered.

An object of the present invention is to solve such a problem by making it possible to intermittently feed the box body and the partition while keeping the relative positional relationship when the tube is packed in the box.

[0007]

In order to achieve the above object, the present invention provides a partition by inserting / removing inserters into / from a part of a plurality of storage chambers formed by a grid-like partition in a box body. A partition positioning device for positioning
Stop the box body when the inserter enters the storage room,
A box intermittent feeding device having a partition including a box body transfer device for intermittently feeding the box body in one direction when the inserter goes out of the storage chamber is adopted.

[0008]

Operation: The partition positioning device operates with respect to the box body to insert / remove the inserter into / from the storage chamber.

The box body transfer device intermittently feeds the box body in one direction each time the inserter comes out of the storage chamber. Also, when the inserter enters the storage room, the box body is stopped. For this reason,
When the box body is temporarily stopped, the partition positioning device restrains the position of the partition inside the box body, and the box body transfer device restrains the position of the box body. Will be kept constant.

Thus, each time the box body is temporarily stopped, the contents insertion device such as a tube inserts the contents into the storage chamber of the box body. Since the partition holds a predetermined prescribed position with respect to the box body, the contents smoothly enter each storage chamber without colliding with the partition or the like.
