BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box folding apparatus and method capable of continuously and automatically folding the top flap of a packaging box in which articles are packed.

[0002]

2. Description of the Related Art Conventionally, folding of a top flap of a packaging box in which articles are packed is complicated because the folding operation has a plurality of steps. Therefore, in order to mechanize the folding operation, a complicated structure corresponding to these operations is required. Is required, and the entire apparatus becomes large and expensive.

Further, since the folding is insufficient and the top flap is opened or lifted up, manual rework is required.

Moreover, when the shape of the packaging box to be processed is changed, it is necessary to replace the whole of these devices, so it takes a lot of time to change the mold and the operation rate of the main work is greatly reduced. At the same time, the storage of these multiple types of devices was extremely troublesome. There were various problems such as.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and an operation means provided in the vicinity of a transfer means of a packaging box is provided with a top flap attached to a support. By attaching a fitting member consisting of a holding member and a pushing member that is attached to the support member and moved forward and backward by the feeding means, the folding of the top flap of the packaging box in which the articles are packed can be performed continuously and with a simple structure. It is an object of the present invention to provide a packaging box folding device and method that can be automatically performed.

[0006]

The means of the present invention for achieving the above-mentioned object is an operating means provided in the vicinity of a transfer means for placing a packaging box and transferring it in one direction, The fitting means is attached to the actuating means and engages with and disengages from the top flap of the packaging box. The fitting means includes a holding member for the top flap attached to the support and the support. And a push-in body which is attached and is moved forward and backward by the feeding means.

Further, in the method of folding the packaging box, the operating means is made to correspond to the packaging box on the transfer means, and the holding member of the fitting means in the operating means is brought into contact with the top flap and lifted upward to lift the top flap. The front end piece is bent inward from the front side piece of the packaging box by the pushing body, and the top flap is lowered by the holding member to insert the tip piece into the packaging box.

[0008]

The packaging box folding apparatus and method according to the present invention having the above-described structure have the following operations.

When the packing box in which the article is inserted is placed by the transfer means and continuously transferred in one direction, the holding member of the fitting means that is lowered by the operating means is placed on the upper surface of the top flap of the packing box c. Correspondingly hold this.

Then, by the operation of the feeding means, the pushing body bends the tip end piece of the top flap toward the packaging box c side at a predetermined angle, and the pushing body maintains this protruding state.

In this state, the fitting means is operated by the actuating means to rotate the top surface flap in the opening direction, and then the pressing body is further protruded and further bent toward the packaging box c.

Next, when the pushing body is retracted with the fitting means being lowered, the tip piece is brought into contact with the inner wall of the front side piece in the packaging box by its own restoring force and is locked. At this time, when the fitting means is further lowered, the tip piece is surely inserted into the packaging box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a packaging box folding apparatus and method according to the present invention will be described below with reference to the drawings.

1 to 3, reference numeral A designates a packaging box folding device which adopts a packaging box folding method according to an embodiment of the present invention, and is basically constituted by an operating means 1 and a fitting means 2. To be done.

Contents b used in the device A of the present invention
As shown in FIG. 4, the packaging box c in which the upper side is opened is provided with inner flaps c1 and c1 on both sides, and one side is rotatably attached to the top flap c2 that closes the opening. Therefore, a tip piece c3, which is bent and inserted into the front piece c4 of the box c, is attached to the end of the top flap c2.

The actuating means 1 is the packaging box c.
Is provided in the vicinity of the transfer means 3 such as a chain conveyor having a conventional top plate for mounting and transferring in one direction, and a robot that can move in multiple axes is used.

The above-mentioned fitting means 2 is attached to the actuating means 1 and engages with the top flap c2 of the packaging box c so that the top flap c2 can come into contact with and separate from the top flap c2. Equipped with.

The holding member 4 uses a suction pad by fluid operation, which is attached to a support body 7 which is detachably provided by an attaching / detaching means 6 such as a clutch to a point of action of the operating means 1 by a stay 8. , The top flap c2 is adsorbed and pulled up to a predetermined angle, or the top flap c2 is pushed in.

The pusher 5 is adapted to move forward and backward at a predetermined inclination to the upper front side of the tip piece c3 of the top flap c2, and a feeding means 9 such as a fluid cylinder.
The tip piece c3 is bent downward by the projecting piece 12 operated by, and the pushing of the top flap c2 is ensured by the pushing piece 10 which is attached to the support 7 and provided on substantially the same plane as the suction pad surface. To do.

In the present embodiment, the above-mentioned feeding means 9 includes the air cylinder 9a and the air slide table 9.
In combination with b, the pusher 5 is operated in two stages, that is,
After bending the tip piece c3 about 90 °, it is further about 95 °
However, it is also possible to perform the above-described two-step operation by using a single member or a combination of a single member and the operating means 1.

Therefore, in the previous step, the inner flap c1 and the top flap c2 are folded and the packaging box c transported by the transfer means 1 is lowered by the actuating means 1 as shown in FIG. 5 (a). The suction pad type holding member 4 of the fitting means 2 sucks and holds the upper surface of the top flap c2 of the packaging box c, and as shown in FIG. 5 bends the tip piece c3 of the top flap c2 by about 90 ° toward the packaging box c side, and the pushing body 5 maintains this protruding state.

In this state, as shown in FIG. 5C, after the fitting means 2 is operated to rotate the top flap c2 in the opening direction, the push-in body 5 is further protruded, and in FIG. As shown by the phantom lines, about 5 ° (total 95 °), packaging box c
Bend to the side, and as shown in FIG.
When the pusher body 5 is retracted while lowering the
As shown in (e), the tip piece c3 abuts against and is locked by the inner wall of the front piece c4 in the packaging box c by its own restoring force. At this time, the fitting means 2 is further lowered and held. While the suction force of the member 4 is released, as shown in FIG. 5 (f), the pushing piece 10 surely inserts the tip piece c3 into the packaging box c, and the work is completed.

The fitting means 2 is appropriately changed depending on the shape of the packaging box c to be processed. For example, the number of the suction pads as the holding members 4 may be increased or decreased or the intervals thereof may be changed. Therefore, in accordance with this change, a large number of different types of fitting means 2 are prepared for the receiving base 11 near the actuating means 1 and exchanged.

[0024]

Since the present invention constructed as described above has a simple structure of a holding member and a pushing member, the entire apparatus can be simplified and manufactured at low cost, and folding can be performed. Since it is carried out reliably, no manpower is required.

Further, when the shape of the packaging box to be processed is changed, the mold can be immediately changed by simply replacing the holding member and the pushing body integrally, so that the replacement time required for this is short. Therefore, the operation rate of main work is not reduced. And so on.
