Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a one-ton box manufacturing method and apparatus suitable for manufacturing polygonal cross-section cartons.

As shown in FIG. 1, the carton take-out forming device in a conventional cartoning machine sucks carton materials 1 one by one from a magazine 2 that holds the carton materials 1 to a vacuum suction cup 3 that can move up and down. is lowered in the direction of arrow A and taken out, and moved in the direction of the arrow by the pusher 4 that engages with the ruled line 1a of the carton material 1 until it comes into contact with the forming guide 5, and then the vacuum suction cup 6 is removed from the carton material 1. The vacuum suction cup 6 is lowered in the direction of the arrow C while the ruled line lb of the carton material 1 is brought into contact with the forming guide 5. At this time, the folded carton material 1 is attached to the cylindrical container 7. A space 1 formed by a partition guide 9 of a conveyor 8 that rotates in the two directions of the arrows.
0 and sent to the next process.
In the conventional device described above, the ruled line/lb of carton material 1
The carton material 1 shown in FIG. 2a is formed into a cylindrical container 7 as shown in FIG. Initially, the space 11 inside the carton body has an almost negligible space, and when it is formed into a cylindrical container 7 as shown in FIG. 11
increases rapidly, resulting in a temporary negative pressure state, which is pulled downward by the vacuum suction cup 6, and the third
As shown in Fig. b, the carbon material 1 may be in a so-called "backwards" state, and this tendency is particularly large when the device is operated at high speed. As a result, the outside portion of the carbon material 1 was easily scratched, resulting in an unfavorable appearance.

In particular, when a force plate 20 having a hexagonal cross-sectional shape as shown in FIGS. 4 and 5 is formed using the above-mentioned apparatus, the force plate 20 may be reversed or curved as shown in FIGS. 5b or 5c. The problem of damage to the outer part of the material was likely to occur, making molding difficult.

The present invention has been proposed in view of the above-mentioned points, and it is an object of the present invention to provide a method and apparatus for forming a box with a polygonal cross-section using a simple device. The present invention takes out a piece of hexagonal cross-section ton that has been folded and stacked in advance, and adsorbs the center pieces of the upper and lower surfaces of the folded ton by a pair of upper and lower vacuum suction mechanisms that can move up and down, respectively. After that, the lower vacuum suction mechanism is lowered to open the toner into a nearly rectangular box and folded, and the upper and lower vacuum suction mechanisms are lowered at the same time to supply it to the toner transport basket, and then the upper vacuum Since only the suction mechanism is lowered and the force tons are passed to the basket with a hexagonal cross section, there is no so-called reverse situation, and an extremely simple method ensures that the force tons have a polygonal cross section. It can be made into a box.

Furthermore, the present invention has a mechanism for taking out pre-folded tones one by one, a block that moves up and down along the same axis as a pair of vertically arranged shafts, and a base fixed to the blocks. A pair of upper and lower vacuum suction mechanisms each having a suction cup attached to the tip thereof for suctioning five central pieces of the upper or lower surface of the taken-out tonnage, and a link connected to the block and a rotary cam that drives the same link; It is characterized by comprising a hexagonal cross-sectional force 1 ton transporting basket, which is disposed below the take-out position of the ton, and is driven at a predetermined timing in synchronization with the four vertical movements of the vacuum suction mechanism. A pair of upper and lower vacuum suction mechanisms are installed to adsorb the taken out cartons from above and below, and these are moved up and down by a drive mechanism at predetermined timing to open the cartons. Therefore, while forming the polygonal cross-sectional force ton, the polygonal cross-sectional force ton is supplied into the packet of the force ton conveying mechanism which is driven at a predetermined timing in synchronization with the vertical movement of the vacuum suction mechanism to form the polygonal cross-sectional force ton. As a result, it is possible to obtain a polygonal cross-section force-ton box forming apparatus which has an extremely simple configuration and high production capacity. The present invention will be explained below based on the illustrated embodiments shown in FIGS. 6 to 9. In this embodiment, the manufacturing of a box with a hexagonal cross-sectional strength of tons will be explained as an example, but the present invention is not limited to this. The magazine 20 is made of a material having a hexagonal cross-section as shown in FIGS. 4 and 5, and is similar to the known magazine 21.

It is provided at a position where it engages, and is configured to move forward and backward in the direction of the arrow H by a drive mechanism (not shown).

29 is a presser guide, which is a front guide 21a of the magazine 21.
The carton material 20 is pivoted at one end thereof, is biased in the direction of the arrow H by a spring or the like (not shown), and is adapted to regulate the position of the carton material 20 between it and a guide portion 30a of a guide plate 30, which will be described later. The guide plate 30 is the magazine 2
One end is fixed to the front guide 20a of No. 1, and the other end is fixed to the No. 6 front guide 20a.
As shown in the figure, it has a guide portion 30a that faces the guide 22a of the pedestal 22. Furthermore, a notch hole 30b is provided so that the vacuum suction cup 32 of the upper suction mechanism 31, which will be described later, does not interfere with the guide plate 30 when it moves up and down. The upper suction mechanism 31 includes a plurality of vacuum suction cups 32 (six in this embodiment are used, but the number may be set to an appropriate number depending on the carbon material, paper quality, etc.).

is a chain conveyor to which a conveying packet 48 is integrally attached, and the conveying packet 48 is shaped to match the hexagonal shape to hold the molded tones delivered from the toned molding device, and moves in the direction of the arrow. It's starting to move.

The vacuum suction cups 24, 32, and 40 are each connected to a vacuum generator (not shown) by a vibrator, a hose, etc., and the vacuum suction cup 40 of the lower suction mechanism 39 suctions the lower spring 20b made of a force-toned material. Needless to say, the relationship is such that it does not interfere with the chain conveyor 47 when it descends to the position where the tonnage is delivered to the transport packet 48. Further, the operation order of the pusher advancing and retracting mechanism, the tong material end bending mechanism, the vacuum suction mechanism, the chain conveyor, etc. is set as described below so that the tong removal molding can be carried out smoothly.

In the above configuration, the shaft 27 is moved in the direction of the arrow by a drive source (not shown), the vacuum suction cups 24 are attracted to both ends of the carbon material 20 at the position indicated by the dashed line in FIG. 7, and then the shaft 27 is moved. When returned in the direction of the arrow, the carbon material 20 is bent into the shape shown by the two-dot chain line in FIG. Next, the pusher 28 moves in the direction of the arrow H by a drive mechanism (not shown) and engages with the ruled line 20a of the punch material 20, and slides the central part of the punch material 20 on the pedestal 22 while pressing the punch. After moving the material 20 until the ruled line 20c touches the guide portion 30a of the guide plate 30, the material 20 is returned in the direction opposite to the direction of the arrow. At this time, presser guide 2
9 is in contact with the ruled line 20a of the force-toned material 20, and on the other hand,
The position of the carton material 20 is accurately determined by the contact between the ruled line 20c of the carton material 20 and the guide portion 30a. Next, the vacuum suction cups 32, 40 of the upper and lower vacuum suction mechanisms 31, 39 are lowered and raised to the positions shown in FIG.

Subsequently, as shown in FIGS. 9 and 9c, the upper vacuum suction cup 32 maintains the position shown in FIG. 9a, and the lower vacuum suction cup 40 descends. As a result, the licarton material 20 is opened, its cross-sectional shape gradually approaches a rectangle, and the chain conveyor 47
The transport packet 48 is lowered into the space of the transport packet 48 without interfering with the transport packet 48 attached to the transport packet 48 . Also, Figure 9c
From the position shown in d, l is the upper and lower vacuum suction cups 22, 40.
Both of them descend while maintaining the rectangular shape shown in FIG. 9c, and further, until the positions shown in FIGS. 9d to 9e, only the upper vacuum suction cup 32 descends and the material is conveyed while forming a hexagonal shape. After the seven hexagonal carts are securely delivered and held within the packet 48, the upper and lower vacuum suction cups return to their initial positions. By repeating the above operations, hexagonal shapes are successively taken out and molded. Therefore, according to this embodiment, since the hexagonal cross-section force cartridge is opened from the top and bottom using vacuum suction cups9, the "reverse warp" phenomenon is not observed, and the problem of molding defects is solved. It is possible to form a box reliably, and without forcing it into contact with a forming guide, it is possible to open the box, make it into a nearly rectangular shape, securely crease it, and then form it into a hexagonal shape. This eliminates scratches on the outside of the box, resulting in a more desirable appearance.Also, since the box is made using a non-contact method, there is no need to worry about damage to the outside even when production speeds are increased, and production capacity can be improved.
