The mandrel (3) hangs down from a plurality of positions that equally divide the outer circumference of the upper horizontal rotary plate (1) in the circumferential direction. The container holder (4) consists of four vertical pieces of cross-sectional shape arranged to be bent around the corners of the container blank (B) or the finished container (C), each mandrel (3) Two of them are arranged in the radial direction at a plurality of positions that equally divide the outer circumference of the lower horizontal rotary plate (2) in the circumferential direction so as to be located further outside. A guide rail (80) is arranged below and along the movement path of the container holder (4), and the bottomed cylindrical container material (B) or container held by the guide rail (80) in the holder (4). It is designed to receive and guide the bottom of (C).

The magazine (5) is arranged diagonally below the mandrel (3) which is stopped at the container material supply position. magazine(
In addition to 5), the container material supply device (6) has a magazine (
a guide member (56) provided integrally with the magazine (5); and a horizontally movable horizontal vacuum cleaner oriented to face the container material (B) housed in the magazine (5).
It consists of a cup (51) and a push-up member (58) that can be raised and lowered directly below the mandrel (3).

When the mandrel (3) stops at the container material supply position, the vacuum cup (57) is advanced and the magazine (5)
By adsorbing the container material (B) housed in the container and then moving it backward, the flat container material (B) is taken out from the magazine (5) while being expanded into a rectangular tube shape while being guided by the guide member (5G). It will be done. Then, push up member (58
), the container material (B) pushed up by this is fitted onto the mandrel (3) from below.

The first device group includes a bottom preliminary folding device (7) that creates creases to make it easier to fold the end of the container material (B) that will become the container bottom, and first and second bottom folding devices that sequentially heat the end. Heater (8) (9) and bottom folding device that folds the same end flat! (10) and a bottom sealing device that crimp the same end that has been folded flat! (11), all of which are known. There are a total of six positions where the mandrel (3) stops. Among these positions, the container material supply position is called the first position, and the other positions are called the second, third, etc. in order of the rotation direction of the upper horizontal rotary plate (1).
. . . Assuming that the sixth stop position is assumed, the eight units M(7) to (11) constituting the first device group are arranged in the above-mentioned order from the second stop position to the fifth stop position. Then, at the sixth stop position, there is a container material transfer device 1t (1
2) is located.

As shown in FIGS. 1, 3, and 4, the container material transfer device (12) is for container material removal that can be raised and lowered below the mandrel (3) that is stopped at the transfer position. The upward vacuum cup (59) is inserted into the container holder (4) which is stopped at the same position and the notch in the guide rail (80) just below it, so that it can be raised and lowered. 60

65).

The container blank holder (62) consists of a pair of vertical pieces facing each other in a cross-sectional shape. Fixed guide bar (6
3) is maintained at a distance that allows the bottomed rectangular cylindrical container material (B) to be lightly pressed against the container material holder (62), and holds the container material (8) together with the container material holder (62). And receive and guide that side. A drive sprocket (64) is fixed to the upper end of the vertical drive shaft (66). Although not explained in detail, the vertical drive shaft (66) uses an intermittent drive mechanism similar to that of the horizontal rotary plates (1) (2) to move the container material holder (62) to a position directly below the mandrel (3) and the container holder. (4).The fixed guide bar (63) is moved toward the outer end so as to face the container material holder (62>) stopped directly above the container holder (4). A container material positioning member (67) is provided at the portion.The container material positioning member (67) is formed in approximately the same shape as the container material holder (62), and is fixed to the horizontal rotating wheel (68) at the lower end. Of the two L-shaped flat plate portions of the container material positioning member (61), the fixed guide bar (63) is attached to the flat plate portion perpendicular to the fixed guide bar (63). A fitting notch (69) is provided.

When the mandrel (3) stops at the container material transfer position, the container material removal vacuum cup (59) is raised to remove the bottom surface of the bottomed cylindrical container material (B) fitted onto the mandrel (3). By adsorbing and then lowering the container material (B), the container material holder (62)
and a fixed guide bar (63). When the chain (61) is driven in this manner, the container materials (B) are sequentially sent outward. When the container material (B) reaches directly above the container holder (4), the chain (61) is stopped.

Then, by raising the take-up vacuum cup (60) to adsorb the bottom surface of the container material (B), and then lowering it, the container material (B) is fitted into the container holder (4) and held. Ru. In this way, the operation of transferring the container material (B) from the mandrel (3) to the container holder (4) is performed by driving the upper horizontal rotating plate (1) two pitches each time the lower horizontal rotating plate (2) is driven one pitch. Container material (B)
This is done by transferring two at a time.

The second device group includes a top preliminary folding device 2 (13) that creates a crease in order to make it easier to fold the end of the container material (B) that will become the container top into a roof shape, and a filling device (14) for filling the
a top folding device (15) for folding the same end along the creases made by (13) and finally folding the same end into a roof shape; and a top heater (15) for heating the folded end. 16) and a top sealing device (11) for crimping the same end, both of which are known. There are a total of nine positions at which the container holder (4) stops.

Among these positions, the container material transfer position is called the first position, and the other positions are called second, third, etc. in order of the rotation direction of the lower horizontal rotary plate (2). If it is called the 9th stop position, then the UV lamp (7
0) is placed, and the 5th one where nothing is placed
The multiple units (13) to (17) constituting the second device group are arranged in the above order from the third stop position to the eighth stop position, excluding the stop position. A container discharge device (18) is arranged at the ninth stop position.

As shown in FIGS. 1 and 5, the container ejection device (18) is inserted through a notch in the container holder (4) stopped at its ejection position and the guide rail (80) immediately below it. A container pushing member (11) that can be raised and lowered, a discharge belt conveyor (72) extending outward from the side of the container pushing member (71), and a container holder (4).
) can be moved horizontally across the top of the container pushing member (
73). When the container pushing member (71) is located at the lower limit of its lifting stroke, the upper surface of the container pushing member (71) and the upper surface of the guide rail (80) are flush with each other, and the container pushing member (71) reaches the lower limit of its lifting stroke. When the container is located at the upper limit of
) and the upper feeding surface of the conveyor (72).

When the container holder (4) stops at the container ejection position, the container pushing member (71) is raised to lift and remove the container (C) held there from the container holder (4), and then the container pushing member (71) is moved up. By activating (13), the container (C) is pushed out from above the container pushing member (γ1) onto the conveyor (12). The container (C) placed on the conveyor (72) is then transported to a predetermined location.

Effects of the Invention According to the present invention, the entire packaging machine can be made compact because a series of devices for performing the required packaging work are arranged near the upper horizontal rotary plate and the lower horizontal rotary plate. , the floor space for installing the packaging machine is small.
