[Conventional technology]

Conventionally, a belt-shaped sheet material having heat-adhesive resin layers on both sides is continuously rolled out, this belt-shaped sheet material is folded in half in the longitudinal direction, and is sealed laterally at appropriate intervals.
Either cut the center of the sealed part and separate it, or fold it in half and seal the stacked edges on both sides in the longitudinal direction, and then seal it in the horizontal direction with an appropriate interval, avoiding the sealed part. A bag-like container with one end open is formed by cutting in the direction and separated, and then this bag-like container is formed into a box shape, and then the box-like container is filled with contents, sealed, etc. known (for example, JP-A-61-8
1905, Japanese Unexamined Patent Publication No. 60-204424, etc.), 1 is usually used in these devices.

Means for performing various operations such as sealing, cutting, forming, filling, and sealing are arranged in the longitudinal direction of the device.

[Problem that the invention seeks to solve]

However, in all such conventional devices, when viewed from the top, the winding of the belt-shaped sheet material is arranged with its axis parallel to the longitudinal direction of the device, and the belt-shaped sheet material unwound from the two windings is parallel to the longitudinal direction of the device. It is configured so that it runs transversely to the longitudinal direction of the device, is folded in half, and then runs in the longitudinal direction of the device for sealing and cutting. For this reason, a distance is required from the mounting position of the 20-roller to the folding position, resulting in a problem that the width of the apparatus becomes wider. Especially 2
If the strip-shaped sheet material unrolled from the roll is subjected to some processing before folding in half, such as punching holes in straws, pasting pull tab tape, printing dates, stamping, etc., the installation position of -Ishinomaki number is required. The gap between the folding point and the folding position becomes large, which increases the width of the device, which creates a problem in that the installation space for the device needs to be increased.

The present invention was made in view of these problems, and it is possible to continuously form box-shaped containers by pulling out a belt-shaped sheet material from a roll-up of the belt-shaped sheet material without increasing the width of the device. The purpose of the present invention is to provide an apparatus for manufacturing a box-like container.

[Means for solving problems]

The sheet is guided by guide rollers 4 so as to travel in the XX direction, and the downstream sheet folding device 35 changes the direction almost vertically and folds the sheet in half so that the sheet surface is in the XX direction, and then folds it in half. A sealing device 42 seals the belt-shaped sheet material running in a substantially vertical direction at regular intervals in the lateral direction, and a direction changing roller 47 causes the sealed belt-shaped sheet material to run substantially horizontally in the Y-Y direction. The belt-like sheet material is intermittently conveyed by a predetermined amount by a drive roller 48 disposed downstream of the direction change roller 8, that is, fed by a fixed length, and a cutting device 49 disposed downstream of the drive roller 4B. Accordingly, the belt-shaped sheet material is cut at the sealed portion 45 and separated as a bag-shaped container 55. Furthermore, immediately before the opening of the bag-like container 55 when it is cut by the cutting device 49, a forming device 60 equipped with a rotary disk 61 having a plurality of mandrels 62 in the radial direction is installed so that the central axis of rotation of the rotary disk 61 is When one mandrel 62 is arranged horizontally at approximately the same height as the bag-shaped container 55 and in the Y-Y direction, and is stopped just in front of the opening of one bag-shaped container 55, the bag-shaped container 55

5 is expanded and formed into a box-like container.

[Function] As described above, in the present invention, the belt-like sheet material 3 unwound from the winder 2 is run in the X-X direction, which is the longitudinal direction of the device, until it is folded in half. Even if the distance to the sheet folding device 35 is increased, the width of the device will not increase. Therefore, before folding the belt-shaped sheet material in half, various processing ( for example.

A drive roller 30 and a downstream drive roller 48 are installed to carry out operations such as straw hole punching, pull-tab tape pasting, one-day printing, ruled line stamping, etc.

Reference numeral 151 denotes a lifting rod provided on both sides of the travel path of the container 55, which is provided at a position where the operating lever 150 is pushed up from below, and is configured to be moved up and down by a drive device (9) not shown. Further, a spring (not shown) is connected to the shaft 148 so that the operating lever 150 is pressed against the upper end of the lifting rod 151. The guide plate 130 shown in FIG. 25 is located downstream from station S4, and
As shown in the figure, they are arranged on both sides of the upper end of the carrier 102.

Next, the folding operation of the container opening by the molding machine 140 will be explained. When the carrier 102 travels and transfers the held container 55 directly below the molding machine 140.

The lifting block 141 is in the raised position, and the holding plate 144 and the claw 149 are in a position where they do not come into contact with the container 55.

In this state, when the container 55 reaches a predetermined position and stops.

The lifting block 141 is lowered to the position shown in FIGS. 26 and 28, and the claw 149 is inserted into the opening of the container 55.

Next, the lifting rod 151 rises to push up the operating lever 150 and open the pawl 149 outward.

By this operation, the opening of the container is creased as shown in FIG. 4C. In the above embodiment, after the claws 149 that pushed open both ends of the container opening outward are returned to their original positions,
Although the opening of the container is held between the presser plates 144, the claws 149 remain open and the presser plates 1
44 may be operated to pinch the opening of the container. In this case, when the upper edge of the container is pinched with the holding plate 144, the claw 149 may be pinched together.
Alternatively, a configuration may be adopted in which a portion of the presser plate corresponding to the claw 149 is cut out and the claw 149 is not clipped.

The container 55 that has been creased at station S4 is sent downstream to station S5 (see Figure 2) and sealed, but by the time it reaches station S5, it has been creased due to the restoring force of the container material. Closed apertures tend to open wide. In order to prevent this, as shown in FIG. 27, a presser bar 156 having a fork 155 at its lower end is provided downstream of the molding machine 140 and connected to an air cylinder 157 for raising and lowering. As shown in FIG.
