Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a composite container for liquid distribution.

Traditionally, glass bottles were the main type of container for liquid distribution, but they are heavy and expensive to transport, and are also disadvantageous in terms of resource conservation, so in recent years plastic containers that are molded in one piece have been used. and paper carton containers are often used.

However, these containers have the following drawbacks. In other words, for relatively large capacity plastic containers,
Because the capacity of the container forming machine is small and it is uneconomical to incorporate it into a high-speed filling machine, the forming of the container and the filling of the container with liquid are usually performed at separate locations by different companies. Therefore, it is necessary to transport the containers formed at the container manufacturing site to the filling site, and since plastic containers are light but bulky, transportation efficiency is poor and transportation costs are high. Also, with plastic alone, airtightness (
Poor gas barrier properties, not suitable for long-term distribution and storage of liquid products. On the other hand, in the case of paper carton containers, when the carton blank is folded and heat-sealed, the aluminum foil or plastic coating layer covering the carton blank may break or pinholes may occur therein. In addition, because the strength of the bottom is weak, various problems occur during distribution. In order to solve the above problems, the applicant has developed a rectangular cylindrical body that can be folded into a flat shape, a plastic bottom part and a Q-mouth part that are made separately from the body part and are joined to both ends of the body part. proposed a composite container whose body has at least an inner plastic layer, an intermediate metal foil, and an outer layer.

further rotates counterclockwise to the above-mentioned retracted position and remains at this position until the holder 21 starts rotating again.
On the other hand, the movement guide 45 moves as shown by the chain line in FIG. 11 until just before the stopped holder 21 starts to rotate.
It is stopped at the guide position b closest to the fixed guide 44, and in order to avoid interference with the trunk removal arm 46, it is rotated counterclockwise in FIG. A little before the take-out arm 46 reaches the body suction position a, the fixed guide 4.
4 to the farthest retracted position c and then stops. Then, when the trunk removal arm 46 that has sucked the trunk 1 rotates counterclockwise and the trunk 1 approaches the fixed guide 44 to some extent, the moving guide 45 rotates clockwise from the retracted position c. After the body 1 reaches the fixed guide 44 and is separated from the body extracting arm 46, it reaches the guide position b and the body 1 is sandwiched between the fixed guide 44 and the body 1 is moved back to the holder 21.
It stops at this position b until it starts rotating. Furthermore, when the stopped holder 21 starts to rotate, the lipter 4r is stopped at the upper end position d shown by the chain line in FIG. starts to descend before it reaches the trunk suction position a, and after the trunk removal arm 46 that has suctioned the trunk 1 begins to rotate counterclockwise, the movement guide 45 moves to the retraction position c.
10 until it starts rotating clockwise, it reaches the lower end position e shown by the solid line in FIG. 10 and stops. As described above, the body part 1 is transferred from the magazine 43 by the body part take-out arm 46 onto the liptor 4γ stopped at the lower end position e, and after the moving guide 45 reaches the guide position b. Lipta4γ begins to rise. Since the trunk supply section 39 of the trunk forming device 14 is not provided with a cam for regulating the position of the movable clamp member 30 of the holder 21, when the holder 21 stops at the trunk supply section 39, the holder 21 is completely removed. is open to Therefore, due to the rise of Lipta 4r, 2
The bent edges on both sides of the heavily folded body part 1 are the holders 21.
The body 1 is fitted with two sets of guides 44,
45 and the bottom 32 of the recess of the clamp members 29, 30 of the holder 21 and rises. Then, when the lipter 4r reaches the upper end position d, the body portion 1 is moved to the guides 44, 4.
After that, the holder 21 is inserted between the bottoms 32 of the recesses of the clamp members 29 and 30 of the holder 21.
The body rotates and moves to the trunk opening 40 while holding the two heavily folded trunks 1. The container body 1 moved to the body opening 40 of the body forming device 14 is expanded slightly into a cylindrical shape by the body opening device rγ.

That is, the pusher R8 of the trunk opening device Rr is in the advanced position when the holder 21 starts to rotate, and while the holder 21 is rotating, the pusher R8 is in the advanced position, and as shown in FIG.
When the holder 21 moves to the retracted position farthest from the body opening 40 and stops at the trunk opening 40, the roller 38 of the holder 21 comes into contact with the pusher R8 in this retracted state. Then, the fixed clamp member 29 and the movable clamp member 30 of the holder 21
The mutual spacing between the holder 21 and the holder 21 is almost the same as when the holder 21 is completely opened. On the other hand, the upper and lower vacuum suction cups R9 of the body opening device Rr are stopped at the retracted positions furthest vertically from the holder 21 from a little after the holder 21 starts rotating until a little before the holder 21 stops. . Note that since the operation of the upper and lower suction cups R9 is vertically symmetrical, the following operation explanation will be given only for the upper suction cup R9 (Figs. 13 to 1).
(See Figure 5). When the upper suction cup R9 is in the retracted position at the upper end, the second elevating body 86 has moved upward away from the stopper 8r, and the vertical distance between it and the first elevating body 84 is at its maximum due to the force of the spring 89. It's getting bigger. Accordingly, the upper ends of the pair of doglegged links 91 are rotated by the link 90 in a direction in which they approach each other, which opens the pair of suction cups R9 and creates a predetermined gap between them. There is. Shortly before the holder 21 stops, the horizontal drive shaft 93 of the suction cup R9 starts to rotate, and the fixed lever 94 fixed thereto is rotated clockwise in FIG. 13. The fixed lever 94 is connected to the connecting member 97 and the connecting recess 98.
The rotary lever 95 is rotated in the same direction via the drive rod 92, and the rotary lever 95 is rotated via the drive rod 92 to the first elevating body 84.
lower. As the first elevating body 84 descends, the second elevating body 86 descends while maintaining the maximum distance between it and the first elevating body 84, and also descends with the pair of suction cups R9 open. The fixed clamp member 2 of the holder 21 in a stopped state
9 and the movable clamp member 30, and the second elevating body 86 eventually comes into contact with the stopper 8r and stops. When the second elevating body 86 stops, the pair of suction cups 79 face both upper surfaces of the body 1 held by the holder 21, and at this time the suction cups R9 start operating. The first elevating body 84 further descends against the force of the spring 89, and as a result, the vertical distance between the two elevating bodies 84 and 86 gradually becomes smaller, and the upper ends of the pair of doglegged links 91 are raised by the links 90. Since they are rotated in directions away from each other, the pair of suction cups R9 closes and suctions both sides of the body 1. When the suction cup T9 closes, the drive shaft 93, that is, the first elevating body 84 stops, and a little later, the drive shaft 93 rotates counterclockwise in FIG. begins to rise, and at the same time Pushya R8 begins to advance. As the first elevating body 84 rises, the second elevating body 8 gradually rises.
6 becomes larger, the suction cup R9 opens, and both sides of the doubly folded body 1 are pulled apart from each other. At the same time, the movable clamp member 30 of the holder 21 is pushed by the pusher γ8 and approaches the fixed clamp member 29, so that the body 1 is expanded into a diamond shape. In this way, hold both sides of the double-folded body part 1 with the suction cup R9.
While pulling both sides with the clamp members 29,
Since the body part 1 is opened by pushing with the clamp members 29 and 30, there is no risk of the body part 1 being bent to one side in a dogleg shape, unlike when simply pressing both ends of the body part 1 with the clamp members 29, 30. When the pusher R8 moves to the advanced end and the opening of the body part 1 is completed, the suction cup R9 stops operating and releases the body part 1, and eventually the vertical distance between the two elevating bodies 84 and 86 reaches the maximum, and the suction is completed. With the board R9 open, these are raised to the upper end retracted position. Immediately before the suction cup '9 returns to the retracted position, the rotating body 20
begins to rotate, and the holder 21 holding the opened body 1
The roller 38 of the pusher R8 is stopped at the advanced position.
Then, it moves to the cam 112 and moves along the cam 112 to the bent portion of the body. Then, while the holder 21 moves along the cam 112, the distance between the clamp members 29 and 30 gradually becomes smaller, and when the body part 1 reaches the bent part 41, the body part 1 is deformed until it becomes nearly square. I'm forced to. In addition, when the upper suction cup R9 rises,
If the rotating lever 95 continues to rotate in the event that it collides with the holder 21 or the like, the device will be damaged. However, in the case of the opening device Rr, if the resistance to the movement of the first elevating body 84 and the rotating lever 95 increases to a certain extent due to a collision of the suction cup 79, etc.
The connecting member 9r of the rotating lever 95 is pushed by the fixed lever 94 and comes off from the connecting recess 98, and the fixed lever 9
4 and the rotating lever 95 are separated. The fixed lever 94 separated from the rotating lever 95 is further rotated by the drive shaft 93, but the deviation in the rotational direction of these levers 94, 95 is detected by the limit switch, the device is stopped, and the necessary An alert will be issued accordingly. Therefore, damage to the device due to collision of the suction cup R9 or the like is prevented. The same applies to the lower suction cup R9 and the lipor 4r of the trunk supply device 15. The container body 1 moved to the body folding unit 41 of the body forming device 14 is bent into a rectangular tube shape along six fold lines 8 by the body folding device 100 .

That is, while the holder 21 is rotating, the busher 101 of the trunk folding device 100 is stopped at the retracted position as shown in FIG. 38 is from cam 112 to pusher 1
01 and stop. At this time, the movable clamp member 30 of the holder 21 is in a position f slightly open from the completely closed state as shown by the chain line in FIG. There is a relatively small gap between the vertical surface 33 and the corresponding vertical surface 33. On the other hand, the mandrel 102 of the trunk folding device 100 is stopped at the lower end retracted position farthest downward from the holder 21 from a little after the holder 21 starts rotating until a little before the holder 21 stops. starts to rise slightly before it stops, and enters the inside of the body 1 held by the holder 21 in the stopped state. Then, as shown in FIG. 16, when the mandrel 102 is completely fitted inside the body 1 and stopped at the upper end operating position, the pusher 101 starts advancing and is pushed by the moving clamp of the holder 21. Member 30
gradually approaches the fixed clamp member 29. The movable clamp member 30 moves to a position where the body 1 and the mandrel 102 are sandwiched between it and the fixed clamp member 29, as shown by the solid line in FIG. 18, that is, a position where the holder 21 is completely closed, and then stops. 1 is these clamp members 29, 3
It is strongly sandwiched between the wide vertical surfaces 33, 34 of the clamp members 29, 34 and the outer surface of the mandrel 102 and bent into a rectangular tube shape, and a portion of the body 1 is connected to the narrowest vertical surface of each clamp member 29, 30. A folded portion 9 is formed by being strongly sandwiched between the surface 35 and the corresponding vertical surface 33. When the bending of the body part 1 is completed in this way, the pusher 101 moves to the retracted position, which slightly widens the gap between the fixed clamp member 29 and the movable clamp member 30, but the body part 1 is Then, it expands slightly and is held closely by the clamp members 29 and 30 as before bending. After the pusher 101 moves to the retracted position, the mandrel 102 begins to descend, and just before the mandrel 102 returns to the lower end retracted position, the rotating body 20 starts rotating, and the rollers of the holder 21 holding the body 1 after bending 38 moves from the pusher 101 to the cam 113 and moves along the cam 113 to the trunk transfer section 42. In addition, if the mandrel 102 collides with the ten thousand holder 21 etc. while going up and down,
The safety device operates in the same manner as in the case of the suction cup γ9 of the trunk opening device RT. The container body 1 that has been moved to the body transfer section 42 is
The holder 2 of the trunk forming device 14 is moved by the trunk transferring device 1T.
1 to the holder 116 of the container assembly device 16. That is, the rotating body 20 of the body forming device 14 and the rotating body 115 of the container assembly device 16 rotate and stop at the same time, and the holder 21 of the body forming device 14 holding the bent body 1 transfers the body. At the same time that the empty holder 116 of the container assembly device 16 stops directly above the body guide 142 of the section 42, the empty holder 116 stops directly below the guide 142. The pusher 185 provided on the container assembly device 16 of the trunk transfer section 42 is connected to the holder 1.
When the holder 16 starts to rotate, it is stopped at the closed position g closest to the holder 116 as shown by the chain line in FIG. 19, and while the holder 116 is rotating, the holder 116 Move to the open position furthest from. Then, the roller 134 of the holder 116 comes into contact with the pusher 185 in the open position and stops, and at this time the holder 116
is slightly open rather than fully closed. On the other hand, when the holder 21 of the trunk forming device 14 also stops at the trunk transfer section 42, it is slightly opened from the completely closed state. The pusher 144 of the trunk transfer device 1T is connected to the holders 21 and 116.
As shown by the solid line in FIG. 23, from when the holder 21 starts to rotate until just before it stops, the holder 21,
The clamp members 29 and 30 of the holder 21 of the torso forming device 14 in the stopped state start descending shortly before 116 stops.
and between the blocks 149 and 150 of the guide 142, and descends to the lower end position immediately above the holder 116 of the container assembly device 16. At this time, 4 of Pushya 144
The short side 165 of the frame fits into the grooves 36 of the vertical surfaces 33, 34 of the holder 21 and the grooves 155 of the guide surfaces 152, 153 of the guide 142, so that the upper end of the side surface of the body 1 facing these grooves 36, 155 is pushed downward, whereby the barrel 1 is transferred from the holder 21 of the barrel forming device 14 to the holder 116 of the container assembly device 16 through the guide 142. The trunk switcher 143 of the trunk transfer device 1T is connected to the holders 21 and 116.
While it is rotating, it is stopped at the lower end retracted position as shown by the solid line in FIG. It rises to the upper end operating position immediately below and stops. Then, as described above, the holder 1 of the container assembly device 16 is
16, the body 1 hits the stopper 143 at the upper end operating position and stops at a fixed position within the holder 116. The pusher 144, which has descended to the lower end position and transferred the trunk 1, immediately begins to rise and returns to the upper end retracted position when the holders 21, 116 begin to rotate again. Also, stopper 143
After the pusher 144 starts to rise, it starts to fall and returns to the lower end retracted position. After this, the holders 21, 11
6 begins to rotate (and the pusher 185 of the container assembly device 16 moves to the closed position g to further reduce the opening degree of the holder 116. Then, the holder 116 holding the body 1
moves from the pusher 185 in the closed position g to the cam 181 and moves along the cam 181 to the bottom/mouth supply part 135. In addition, when the pusher 144 of the trunk transfer device 1r collides with the ten thousand holders 21, 116, the guide 142, etc. while moving up and down, the safety device is activated in the same manner as described above. The container bottom 2 and the container mouth 3 are fitted into the lower and upper ends of the container body 1 that has been moved to the bottom and mouth supply section 135 of the container assembly device 16 by the bottom and mouth supply device 192 .

That is, when the holder 116 starts to rotate, the pusher 18r of the bottom/mouth supply part 135 is stopped at the closed position h closest to the holder 116, as shown by the chain line in FIG. While this is happening, it moves to the open position farthest from the holder 116, as shown by the solid line in FIG. Then, the roller 134 of the holder 116 comes into contact with the pusher 18r in the open position and stops, and at this time the holder 116 is slightly opened from the completely closed state. The degree of opening of the holder 116 at this time is the same as the degree of opening of the holder 116 when the pusher 185 in the trunk transfer section 42 is closed. When the holder 116 starts rotating,
Upper and lower lifting table 196 for bottom/mouth supply device 192
, 195 are stopped at the furthest retracted position vertically from the holder 116, and these elevating tables 196, 19
The movement stoppers 21r and 226 of No. 5 are about to close. Also, the stoppers 208 of the mouth chute 194 and the bottom chute 193 are in the third position while the holder 116 is stopped.
It is in the operating position as shown by the solid line in Figure 1, and the leading mouth part 3
And the bottom part 2 is hooked and stopped on the chutes 194, 193. Then, before and after the holder 116 starts rotating, the stopper 208 rotates to the non-operating position 1 as shown by the chain line in FIG. It then returns to its working position. The mouth portion 3 and bottom portion 2 sent out from the chute 194, 193 fit into the holes 213, 222 of the lifting tables 196, 195 that are stopped at the retracted position, and are received by the moving stopper 21 (226) in the closed state. Stop. The mouth chuck 198 and the bottom chuck 19r are connected to the chute 194, 19 while the holder 116 is rotating.
When the mouth part 3 and the bottom part 2 are sent out from the lift table 1, 96, 195 from the lift table 1, the mouth part 3 and the bottom part 2 are at the retracted position vertically farthest from the holder 116, and the mouth part chuck 198 is opened.
The bottom chuck 19γ is closed (see Figure 39a).
The mouth part 3 and the bottom part 2 are connected to the lifting table 196,1.
95 and the stoppers 208 of the chute 194, 193 return to the operating position, the mouth chuck 198 begins to descend in the open state, and the bottom chuck 19
When r is closed, it begins to rise. And the holder 116
Shortly before the upper and lower chucks 198 and 19r stop, the upper and lower chucks 198 and 19r stop at the intermediate position, and the mouth chuck 198 closes and grasps the upper cylindrical part of the mouth part 3 from the outside, and the bottom chuck 19
r opens and grips the inner circumferential surface of the horizontal flange 10 at the lower end of the bottom 2 from the inside. After the upper and lower chucks 198, 19r grip the mouth part 3 and the bottom part 2, the upper and lower lifting tables 196, 19
5 open, one of the two mouth chucks 198 and one of the two bottom chucks 19r rotate one mouth part 3 and bottom part 2 by 90 degrees together with the horizontal rotating disk 31r and stop. do. The rotation of these chucks 198 and 19γ causes the protrusions 13 and 11 on the mouth portion 3 and the bottom portion 2 to
This is necessary in order to match the folded portion 9 of. That is, when the mouth part 3 is fed by the chute 194, the two parts of the mouth part 3 are
However, as shown in FIG. 32, since the two mouth chute 194 form a right angle when viewed from the top, the chute 194 is connected to the upper elevating table 1.
The protrusions 13 of the two mouth parts 3 sent into the holes 213 of 96
The orientations of the two are not aligned and are shifted by 90 degrees from each other. On the other hand, since the directions of the folded portions 9 of the two body portions 1 held by the holder 116 are the same, the folded portions 9 of one of the body portions 1 and the corresponding protrusion 13 of the mouth portion 3 It always deviates from 90. Therefore, by rotating this mouth portion 3 by 909 degrees, the folded portions 9 and 2 of the two body portions 1 are folded.
The protrusions 13 of the two mouth portions 3 match. The same applies to the bottom portion 2. Next, at the same time as the upper and lower chucks 198, 19γ finish rotating, the upper elevating table 196 and the mouth chuck 198 begin to descend, the lowering elevating table 195 and the bottom chuck 19r begin to rise, and eventually the upper and lower elevating table 196 , 195 are stopped slightly above and below the holder 116, respectively. At this time, the lower part of the guide plate 216 of the upper lifting table 196 and the upper part of the guide plate 224 of the lower lifting table 195 are connected to the trunk 1.
Enter from above and below. Upper and lower lifting table 196,1
When the holder 95 stops, the pusher 18r moves to the closed position h to further reduce the opening degree of the holder 116. Even after the upper and lower lifting tables 196 and 195 have stopped, the mouth chuck 198 further descends and the bottom chuck 1
9r is raised, whereby the opening 3 and the bottom 2 are guided by the guide plates 216, 224 and fitted into the upper and lower ends of the body 1 (see the opening in FIG. 39). At this time, the guide plates 216 and 224 act like shoehorns, and the mouth portion 3 and the bottom portion 2 are smoothly fitted into the body portion 1. When the mouth part 3 and the bottom part 2 are roughly fitted into the body part 1, the upper lifting table 19
6 begins to rise, the lower elevating table 195 begins to descend, and eventually these elevating tables 196, 19
5 reaches the retracted position and stops. Elevating table 196,
When 195 moves up and down, the mouth 3 and bottom 2 are held by chucks 198 and 191, so the guide plate 21
6, 224 are removed vertically from between the mouth portion 3 and the bottom portion 2 and the body portion 1 (see FIG. 39C). When the mouth part 3 and the bottom part 2 are completely fitted into the body part 1, the upper and lower chucks 198
, 19' stop, and eventually the mouth chuck 198 opens and moves up after releasing the mouth 3, while the bottom chuck 19r closes and moves down after releasing the bottom 2.

As a result, only the mouth portion 3 and the bottom portion 2 remain fitted into the body portion 1, and the holder 116 holding such a body portion 1 is removed.
moves from the pusher 18r in the closed position h to the cam 182 and moves along the cam 182 to the first joint 136. Then, when the holder 116 starts to rotate, the movement stopper 21 of the upper and lower lifting tables 196, 195
26 is closed, and the upper and lower chucks 19 are opened while the holder 116 is rotating.
8,19r returns to the retracted position. Note that when next feeding the mouth part 3 and the bottom part 2 to the body part 1 stopped at the bottom/mouth part supply section 135, one of the mouth chucks 198 and one of the bottom chucks 19γ is rotated 90 degrees in the opposite direction to the above.゜Rotate. The body part 1 that has been moved to the first joint part 136 and the bottom part 2 and mouth part 3 fitted therein are transferred to the joining device 285
are joined to each other by.

That is, when the holder 116 starts rotating, the pusher 188 of the first joint 136 is stopped at the closed position j closest to the holder 116, as shown by the chain line in FIG. 19, the holder 116 is moved to the open position farthest from the holder 116, as shown by the solid line in FIG. Then, the roller 134 of the holder 116 comes into contact with the pusher 188 in the open position and stops, and at this time the holder 116 is slightly opened from the completely closed state. The opening degree of the holder 116 at this time is the same as the opening degree when the pusher 18r in the bottom/mouth supply section 135 is closed. When the holder 116 is rotating, as shown in FIG.
The piston rod 265 is in the retracted position, the holder pressing rod 26r stops at the retracted position farthest outward from the holder 116, and the upper and lower direct-acting cams 268, 269 move to the outermost position (right side in Fig. 40). are doing. For this reason,
The rollers 2'9, 284 of the upper and lower elevating bodies 2r3, 288 fit into the tips of the cam grooves 2r0, 2r1 of these cams 268, 269, and the upper and lower pressing members 2r6, 282 are moved to the recesses furthest vertically from the holder 116. stopped in position.
After the holder 116 has stopped, the cylinder 264
The piston rod 265 advances, thereby causing the holder pressing rod 26r and the upper and lower translational cams 268, 269 to move inward. By the movement of the upper and lower translational cams 268 and 269, the upper and lower pressing members 2r6 and 282 are moved into the cam groove 2, respectively.
moving downward and upward along r0,2T1, spring 2
The mouth part 3 and the bottom part 2 are pushed by the force of γ8, 283 to completely fit into the body part 1. At the same time, the holder pressing rod 26
r pushes the movable body 124 of the holder 116, that is, the movable clamp member 125, inward to completely close the holder 116,
After this, the pusher 188 moves to the closed position j. on the other hand,
When the holder 116 stops, the primary coupling coil 256 and the secondary coupling coil 13 are
A high frequency current is supplied to the high frequency heating coil 131 through 2, thereby heating the holder 116 and joining the mouth portion 3 and the bottom portion 2 to the body portion 1. When the first joining is completed in this way, the piston rod 265 of the cylinder 264 is retracted, and the holder pressing rod 26γ and the mouth pressing member 2
After γ6 and the bottom pressing member 282 return to the retracted position, the holder 116 rotates and the pusher 18 in the closed position j
8 to the cam 183, and moves along the cam 183 to the second self-contact multiplier 1s13r. Second tangent multiplier 1s13r
The holder 116 that has been moved to is completely closed, and the body 1, bottom 2, and mouth 3 held therein are joined for the second time by the joining device 286 in the same manner as described above, and these are completely closed. Joined. The container A assembled in this manner is sent along the cam 183 to the discharge section 139 via the cooling section 138. Cooling water is constantly flowing through the high-frequency heating coil 131 of the holder 116, and the completed container A
is cooled while reaching the discharge part 139 from the second joint part 13r. The container A that has been moved to the discharge section 139 is discharged by the container discharge device 18.

That is, when the holder 116 begins to rotate, the pusher 186 of the ejection part 139 is stopped at the open position farthest from the holder 116, as shown by the solid line in FIG.
Shortly after the holder 116 begins to rotate, it moves to the open position k closest to the holder 116, as shown by the chain line in FIG. The holder 116 holding the completed container A after joining is transferred from the cam 183 to the pusher 186 in the closed state, and shortly before the holder 116 stops, the pusher 186 moves to the open position, thereby completely closing the holder 116. Open slightly from the position. The timing screw 292 of the container ejector 18 stops shortly after the holder 116 stops;
As a result, the empty container storage body 291 is positioned directly below the two completed containers A held by the holder 116. On the other hand, when the holder 116 starts to rotate, the pusher 301 of the container ejecting device 293 is at the upper end retracted position upwardly away from the holder 116 as shown in FIG. The container A held in the holder 116 stopped at 139 is pushed downward and moved down inside the holder 116. As a result, the completed container A is moved from the holder 116 to the container 2 that is stopped directly below it.
91, the pusher 301 rises again and returns to the upper end retracted position when the holder 116 begins to rotate. Further, after the completed container A is transferred to the container 291, the timing screw 292 rotates until a little while after the holder 116 rotates again and stops, ejecting the container 291 containing the completed container A and ejecting the container 291 to the next one. The empty container 291 is carried into the discharge section 139. Then, the container 291 containing the completed container A is discharged by the conveyor 290. Note that the pusher 301 of the container extrusion device 293
If it collides with the ten thousand holder 116 or the like while going up and down, as in the case of the suction cup 79 of the body opening device Rr,
The connecting piece 310 of the fixed lever 305 is disengaged from the connecting recess 314 of the rotating lever 312, and the safety device is activated. The structure of the composite container A is not limited to that of the above embodiment, and can be modified as appropriate. In addition, a trunk forming device 14, a trunk supplying device 1
5. The container assembly device 16, the trunk transfer device 1r, and the container discharge device 18 are not limited to those in the above embodiment, and can be modified as appropriate. For example, in the above embodiment, the body forming device 1
