DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag mounting device for mounting a resin bag inside a box having an open top, for example.

[0002]

2. Description of the Related Art In general, in a collection and delivery center such as a co-op, a styrofoam box or a plastic container is packed with food and other goods and articles and delivered to a store or a customer, and the box is collected and reused. I have. Usually, food is packed after a thin resin film bag is attached to a box.
By using such a bag, the inner surface of the box can be prevented from being stained, and food and the like can be taken out and handed to a store or a customer, and the box can be collected on the spot.

Conventionally, the mounting of bags in such boxes has been performed manually, but recently, due to the labor and inefficiency, a bag mounting apparatus which can automatically perform this work has been recently used. (For example, Japanese Patent Publication No. 4-42242).

The letters "BC" are displayed in the correct orientation.

Thereafter, as shown in FIG.
The bag 100 in which the insertion of 01 has been completed is taken out of the box 7 by grasping the open end thereof by hand. In this case, the letters “ABC” printed on the middle part of the bag 100 are displayed in the correct direction. On the other hand, the character "ABC" printed on the opening end of the bag 100 is displayed upside down, but this character does not pose a problem because most of the character is hidden by hand.

On the other hand, in the case of the bag mounting apparatus of the present embodiment,
After all operations are completed, for example, when an instruction to that effect is given on the operation panel 10, the upper claw 31 moves to the vicinity of the bag material cutting mechanism 32 and grips the leading end portion of the bag material 12, and this is moved to the entrance side. Return to the home position S and the drive motor 16
Is driven to wind up the bag material 12 around the film roll 11. When the bag mounting apparatus 2 is restarted, the above-described operation is performed with the position as a starting point.

As described above, according to the bag mounting apparatus 2 of the present embodiment, the bag material transporting mechanism 20, the bag material expanding mechanism 51,
52, the bag lowering mechanisms 60 and 61, and the cutter cradle 34 are configured to be linked to the same driving means 80 so as to interlock with each other. The drive error between the intervals can be made extremely small, and a highly accurate bag mounting operation can be performed.

Further, according to the bag mounting apparatus 2 of the present embodiment, by pressing the step roller 41 of the pressing mechanism 38 against the bag material 12, an optimal size for the box 7 having various heights is obtained. The bag mounting operation can be performed by using the bag.

Furthermore, according to the present embodiment, when the bag mounting operation is completed, when restarting, it is necessary to discard the excess portion of the bag material 12 extending downstream from the entrance side fixed position S. Because there is no waste, it is possible to reduce waste and to save resources.

Furthermore, in the present embodiment, when the bag material 12 is expanded, each of the adsorbers 50A, 50B, 50
By relatively moving C and 50D in the direction of the suction surface of the bag material 12, the bag materials 12 are rubbed, so to speak, so that the bag material 12 can be reliably opened.

In addition, according to the present embodiment, a predetermined character is printed on the opening end of the bag 100 by the printing means 35, and the predetermined character is turned upside down on the middle of the bag 100. Thereby, for example, information such as the delivery destination can always be displayed correctly, and the sorting operation can be performed reliably and efficiently.

FIGS. 8 (a) to 8 (e) are explanatory views showing a procedure of a bag mounting operation in the bag mounting facility of the present embodiment. Hereinafter, the bag mounting apparatus 1A shown in FIG. Will be explained. As shown in FIG. 8A, the height of the box 7 conveyed by the upstream belt conveyor 5 is detected by sensors 8 and 9 shown in FIG. Then, based on this detection result, the above-mentioned step roller 41 is lowered to a predetermined position while the bag material 12 is being conveyed.

On the other hand, in the cutting conveyor 4A,
Using the stoppers 4a and 4b, the two boxes 7A and 7B are set as one set and positioned. As shown in FIG. 8B, the box 7 delivered from the cut-out conveyor 4A to the transport conveyor 3 is intermittently moved by a predetermined distance by the transport conveyor 3, and the front box 7A is moved to the first box 7A. It is stopped when it reaches the bag mounting position of the bag mounting device 2A. Then, in this state, the above-described bag mounting operation is performed on the box 7A.

After completion of the bag mounting work on the front box 7A,
As shown in FIG. 8 (c), the boxes 7
Is moved intermittently by a predetermined distance. In this state, the bag 100 is not mounted on the box 7B on the rear side, but is mounted on the box 7C on the front side of the pair of boxes 7C and 7D that are subsequently conveyed.

Next, as shown in FIG. 8D, the box 7 is intermittently moved by a predetermined distance by the conveyor 3, and the box 7B on the rear side of the set of boxes 7A and 7B is moved to the second box. It is stopped when it reaches the bag mounting position of the bag mounting device 2B. Then, in this state, the above-described bag mounting operation is performed on the box 7B.

After completion of the bag attaching operation to the rear box 7B,
The set of boxes 7A and 7B is delivered from the conveyor 3 to the belt conveyor 6 on the downstream side, and is conveyed to a sorting device (not shown). Hereinafter, the bag is mounted on the box 7 in the same procedure.

As described above, according to the bag mounting equipment of the present embodiment, since the two bag mounting devices 2A and 2B are arranged in series on the transport path for transporting the box 7, Can be efficiently performed.

In particular, in the present embodiment, the two boxes 7A and 7B are transported as a set, and the transport means 3 is so arranged that each box 7 stops at a different bag mounting device mounting position.
Is intermittently driven, so that the bag mounting operation on the box 7 can be performed very efficiently and continuously.

Note that the present invention is not limited to the above-described embodiment, and various changes can be made. For example,
In the above-described embodiment, two bag mounting devices are arranged in series on the transport path. However, three or more bag mounting devices may be arranged. In that case, it is preferable to drive the transport means intermittently so that each set of boxes stops at a mounting position of a different bag mounting device, as in the above embodiment.

In the above embodiment, two sensors having different heights are provided on the belt conveyor on the upstream side. However, three or more such sensors may be provided. In that case, it is preferable to provide the pressing position of the step roller for pressing the bag material in accordance with the number of sensors.

[0079]

As described above, according to the present invention, it is possible to provide a bag mounting apparatus capable of accurately mounting bags on boxes having different heights. Further, according to the bag mounting apparatus of the present invention, it is possible to reduce dust caused by the surplus portion of the bag material and to save resources. Furthermore, according to the bag mounting apparatus and the bag mounting equipment of the present invention, the efficiency of the bag mounting operation can be greatly improved.
