Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a taper box making machine used for manufacturing a taper box, for example.

[0002]

2. Description of the Related Art Conventionally, a taper box making machine of this type is known, for example, that disclosed in Japanese Patent Publication No. 58-44074. This is basically the supply of carton blanks in which a body box part and a lid box part are continuously provided around a rotating body that rotates intermittently, gluing, a body box assembly box, a lid box assembly box and a molding box. Each working part for taking out is provided, and it is a pair of male type that can be independently advanced and retracted toward each working part on the rotating body and corresponds to the body box part and lid box part of the carton blank. The pair of male molds are provided with suction cups for sucking and holding the carton blanks respectively, and the body box assembly box part and the lid box assembly box part are provided with the body box male part and the lid box part. It consists of only a female box that can be moved relative to the male box, and the carton blank is bent as the male box approaches and the box and lid boxes are formed separately. The box assembly is located in the body box section above, and the box assembly consisting only of the lid box female is in the box section above the lid box. Each disposed,
By the suction control of the male sucker part that rotates and stops the rotating body and the advancing / retreating control of the paired male type,
The work at each work site is performed when the rotating body is stopped. However, in such a thing, a male type must be provided corresponding to each work section, and each male type must be provided with a suction cup portion for suction-holding a carton blank. In other words, a large number of male molds having a complicated structure were required, so that the mold cost was very high.

Transport belt 13 to send
And the upper and lower feeding belts 14 and feeding rollers 15 which are rotatably provided on the machine body 8 and feed the paper box material A fed upward. In this example, the paper box material A has a bottom piece B, four side pieces C connected to the bottom piece B, four glued pieces D connected to these pieces, and one side piece C. And a lid piece E that has been opened to form a so-called lidded taper box F. The carrying device 3 carries the paper box material A from the paper feeding device 2, and in this example, the machine body 8
The upper and lower take-up rollers 16 provided on the front side to feed the paper box material A from the paper feed device 2 forward, and the paper box material A from the take-up roller 16 rotatably provided on the machine body 8 to push them forward. A carrier chain 17 for feeding to the machine body 8, a feeding body 18 movably provided in the machine body 8 for back and forth to push the paper box material A detached from the carrier chain 17 and feed it forward, Left and right guides 1 for guiding the transported paper box material A
It consists of nine and nine. The gluing device 4 is provided in the middle of the conveying device 3 and glues the gluing piece D of the paper box material A.
In this example, a glue tank 20 that is provided in the machine body 8 and stores the glue G, and a glue tank 2 that is rotatably provided in the machine body 8
The glue roll 21 to which the glue G of 0 is attached, the glue transfer roll 22 that is rotatably provided on the machine body 8 and transfers the glue G from the glue roll 21 to the glued piece D of the paper box material A, and the machine body 8 The pressure roller 23 is rotatably provided and receives the sizing piece D of the paper box material A when sizing. Positioning device 5
Is for positioning the paper box material A from the gluing device 4 at a predetermined position. In this example, the rear half of the left and right guide bodies 19 and the body 8 are provided so as to be movable back and forth. It comprises a stop body 24 for engaging and stopping the front end of the fed paper box material A. The forming device 6 forms the positioned paper box material A into a taper box F including a male mold 25 and a female mold frame 26 that fits the male mold 25. In this example,
A male die 25 in the shape of a quadrangular pyramid that pushes up the bottom piece B of the paper box material A that is provided in the machine body 8 and is vertically movable
And the side of the paper box material A which is provided horizontally on the machine body 8 and is pushed up by the male mold 25 so that the size of the quadrangle formed by these can be varied by providing front, rear, left and right guide plates. The female mold 26 that gradually bends the piece C downward, and the glued piece D of the paper box material A that is provided on the machine body 8 so as to be horizontally movable and pushed up by the male mold 25 are pressed from the side piece C. It is composed of a pressing body 27 which is gradually bent downward. Ejector 7
Is provided in the female mold 26 of the molding apparatus 6 and superimposes and discharges the taper box F from this onward. In this example, the taper box is continuously provided on the upper part of the female mold 26 and comes out from here. F
Are superposed in sequence and guided from above to the front to be discharged. Next, the operation will be described based on such a configuration. A large number of paper box materials A are vertically arranged on the table 10 of the paper feeding device 2, and every time the rocking body 11 moves forward, the frontmost one moves upward between the regulation body 12 and the conveyance belt 13 by the conveyance belt 13. The feeding belt 14 and the feeding roller 15 are conveyed.
Is fed forward and is supplied one by one. The supplied paper box material A is taken up by the take-in roller 16 of the carrying device 3, is pushed backward by the carrying chain 17, and is carried forward. At this time, the guide 19 keeps a predetermined state and guides (see the right side of FIG. 3). The conveyed paper box material A is glued to the glued piece D by the glueing device 4 on the way. That is, the glue G in the glue tank 20 is glued to the glued piece D of the paper box material A that passes from the glue roll 21 via the glue transfer roll 22 and between the glue transfer roll 22 and the pressure roll 23 (FIG. (See center of 3). The glued paper box material A is subsequently pushed forward by the transport chain 17 and transported forward, and is fed forward by the feeding body 18 at a speed faster than the transport speed of the transport chain 17 from before the end of the transport. Then, the front end of the positioning device 5 is brought into contact with the stopper 24 to be positioned at a predetermined position. Positioned paper box material A
The bottom piece B is pushed up by the male die 25 of the molding device 6, the glued piece D is first pressed by the pressing body 27 and bent downward, and then the side piece C is leaned by the female mold 26. Is gradually bent to the lower side, and the glued piece D and the side piece C adjacent thereto
Are adhered to each other to form a tapered box F having a truncated pyramid shape (see the left side of FIG. 3). The formed taper box F is held by the female mold 26, and subsequently the formed taper box F is sequentially polymerized and guided and discharged by the guide of the discharging device 7. The molding apparatus 6 is provided with a male mold 25 and a female mold frame 26 that fits the male mold 25, and since these are each single and have a simple structure, the mold cost does not increase. When manufacturing taper boxes F of different sizes, the male mold 2 of the molding apparatus 6 is manufactured.
5 is replaced with a taper box F, and the front, rear, left and right guide plates of the female frame 26 are horizontally moved to change the size of the quadrangle. Since the male mold 25 may be made of wood, it does not cost much.

Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the paper box material A, the bottom piece B,
Four side pieces C continuously provided to this, and four glued pieces D continuously provided across the adjacent side pieces C and having diagonal fold lines engraved therein
This is different from the first embodiment in that a so-called taper box F having no lid is formed.
