BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a wrapping paper holding device for holding a wrapping paper for receiving an article from a side by an article feeding device, and in particular, supports the lower surface of the wrapping paper so that the lower surface does not rise when the article is supplied. About what you do.

[0002]

2. Description of the Related Art For example, when an article 7 is supplied from the side to a carton 5 as a rectangular tubular wrapping paper having an open side as shown in FIG.
It is necessary to prevent an article from dropping due to a load placed on the article a. Therefore, when the carton 5 is conveyed to the article supply position where the article supply device is arranged, the article supply table in the article supply device approaches the frame 51 of the carton 5, but at this time, the lower flap 52a becomes an obstacle. .

Therefore, conventionally, as shown in FIG. 7, the lower flap 52a is pushed obliquely downward by a pressing piece 300 provided on the side of the wrapping paper holding device 100, and the carton 5 is supplied to the article supply device. Supply table 6 in 6
1 had been transported. Thereby, the lower flap 5
Since 2a is retracted below the article supply table 61, the carton 5 can be conveyed to the article supply device 6 without the lower flap 52a being in the way.

[0004]

However, when the lower flap 52a is pressed down by the pressing piece 300, the carton 5 on the support 200 may be lifted by the stress (indicated by a two-dot chain line in FIG. 7). . Then, a step is generated between the carton lower surface 52a and the article supply table 61.
There is a problem that articles cannot be supplied smoothly due to being supported by the step or falling down.

[0005] The present invention relates to a "wrapping paper holding device for holding a wrapping paper in a side open state in which an article is received from a side by an article feeding device". An object of the present invention is to be accommodated in wrapping paper.

[0006]

Means for Solving the Problems Technical means of the present invention taken to solve the above problems are as follows. `` It is provided with a support for supporting the wrapping paper, and a pressing piece that presses the lower flap at an opening of the wrapping paper on the article receiving side obliquely downward when receiving the article, and disposing suction means below the wrapping paper. In this case, the lower surface of the wrapping paper is suctioned by the suction means. Here, the wrapping paper is a concept including a carton and a cardboard.

The above technical means operates as follows.
When the lower flap at the opening of the article receiving side of the wrapping paper is pushed down obliquely downward by the pressing piece, the wrapping paper itself tends to rise from above the support in conjunction with the stress, but the wrapping is performed by the suction means. Since the lower surface of the paper is adsorbed, such floating of the wrapping paper can be prevented. Thereby, the lower surface of the wrapping paper can be held in a horizontal position on the support.

[0008] In the above technical means, it is preferable that the conveying means installed in the direction perpendicular to the article supply direction by the article supply device constitutes the support, and the conveying means moves the wrapping paper from the wrapping paper receiving position to the article supply position. When the wrapping paper is in a standby state, the pressing piece is retracted, and when the wrapping paper is placed on the support, the lower surface of the wrapping paper is sucked by the suction means, and then the pressing piece is rotated. The lower flap is moved obliquely downward, and the lower flap is diagonally lowered. " When the wrapping paper is placed on the wrapper, the pressing piece does not interfere. And
When the wrapping paper is placed on the conveying means, the suction means is driven by a control command from the control means to hold the lower surface of the wrapping paper in a horizontal position on the support, and then the pressing piece is rotated. Then, the lower flap of the wrapping paper is depressed obliquely downward. In this state, the wrapping paper is moved to the article supply position by the transport means. At this time, the wrapping paper can be made to approach the article supply device without the lower flap of the wrapping paper being in the way, and the lower surface of the wrapping paper and the article supply table in the article supply device are flush with each other. Can be held.

The pressing piece has a driving means, and the driving means rotates the pressing piece between the retracted position and the pressing position of the lower flap. According to the "the suction means is connected to the second transport means for transporting the wrapping paper from the wrapping paper receiving position to the article supply position", the packaging arranged on the support at the wrapping paper receiving position. By adsorbing the lower surface of the paper, the wrapping paper can be firmly held on the support. In this state, by driving the second transport means so as to follow the transport means, the wrapping paper is stably moved to the article supply position without being displaced or falling off from the support. Can be transported.

[0010]

As described above, according to the present invention, since the lower surface of the wrapping paper is held horizontally on the support, the articles are supported by the step on the lower surface of the wrapping paper or fall down when the articles are supplied from the side. It is possible to reliably house the wrapping paper without any trouble such as slipping.
