Description

[Detailed description of the invention] This invention is a joining device for a composite container manufacturing apparatus, more specifically, a collapsible rectangular cylindrical body, and a body made separately from the body and fitted into both ends of the body to be joined. The present invention relates to a joining device for joining the bottom and the mouth part, which are fitted into both ends of the body part formed into a rectangular tube shape, to the body part, in a manufacturing apparatus for a composite container for liquid distribution comprising a bottom part and a mouth part.

Traditionally, glass bottles were the main type of container for liquid distribution, but they are heavy, expensive to transport, and disadvantageous in terms of resource conservation, so in recent years, integrally molded plastic containers and paper carton containers have been used. is often used. However, these containers have the following drawbacks. In other words, in the case of relatively large-capacity plastic containers, the capacity of the container forming machine is small and it is uneconomical to incorporate it into a high-speed filling machine. It is usually held at a different location. 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.
Furthermore, plastic alone has poor airtightness (gas barrier properties) and is 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
A composite container as shown in Figs. That is, this container A consists of a rectangular cylindrical body 1, and a bottom 2 and a mouth 3 that are made separately from the body 1 and are joined to both ends of the body. The body 1 is formed into a cylindrical shape by joining both ends of a single sheet, which is rectangular in the unfolded state, to each other, and has an inner plastic layer 4 made of polyethylene resin or the like having a thickness of about 40 to 60 μm. , an intermediate metal foil 5 such as aluminum foil having a thickness of approximately 10 to 20 μm, and an outer layer 6 such as polyethylene terephthalate resin or paper having a suitable thickness. The body part 1 is provided with six fold lines 8 parallel to the joint part 7, and during storage or transportation before constructing the container A, the body part 1 is symmetrically folded as shown in FIG. It is folded back along two fold lines 8 at certain positions, and the body 1 is folded twice. When configuring the container A, the body 1 has six fold lines 8 so as to form a square shape when viewed from above.
A narrow folded portion 9 is formed in the form of an extension of one side at the two side edges located at symmetrical positions. These folded parts 9
As will be described later, when the bottom part 2 and the mouth part 3 are joined, the inner surfaces are joined together. The bottom part 2 is
It is integrally molded from plastic such as polyethylene resin so as to have a square shape when viewed from above, and is fitted from below inside the lower end of the body 1 and joined to the inner surface of the body 1 in an airtight manner. The four side surfaces of the bottom part 2 that are joined to the inner surface of the body part 1 are integrally formed with outward horizontal flanges 10 that contact the lower end of the body part 1, and the two side edges at symmetrical positions are provided with the body part 1. Thin protrusions 11 are integrally formed, which are sandwiched and joined to the folded portions 9 of 1. The mouth part 3 is integrally molded from plastic such as polyethylene resin so as to have a square shape when viewed from above, and its lower end is shaped like a square.
It is fitted into the inside of the upper end of the body part 1 from above,
It is joined to the inner surface of the body part 1 in an airtight manner. Four side surfaces of the mouth portion 3 that are joined to the inner surface of the body portion 1 are integrally formed with outward horizontal flanges 12 that contact the upper end of the body portion 1. A thin protrusion 13 is integrally formed to be sandwiched and joined to the folded portion 9 of the portion 1.

The above-mentioned container A consists of a collapsible rectangular cylindrical body 1, and a bottom 2 and a mouth 3 that are made separately from the body 1 and are joined to both ends of the body. can be transported separately and form the container A with them at the liquid filling location. Therefore, each of these parts 1, 2,
The body 1 can be folded while the container 3 is being transported from the container manufacturing site to the liquid filling site, reducing the bulk, resulting in good transportation efficiency and low transportation costs. Further, the body 1 includes at least an inner plastic layer 4, an intermediate metal foil 5, and an outer layer 6.
Therefore, there is no possibility that defects such as pinholes will occur, and high airtightness can be obtained by the metal foil 5. Furthermore, since the bottom part 2 is made of plastic, it has sufficient strength.

When manufacturing the container A as described above, it is necessary to form the double-folded body 1 into a rectangular tube shape, and then fit and join the bottom 2 and the mouth 3 to both ends of the body.

The purpose of this invention is to provide a joining device that can reliably and efficiently join a bottom part and a mouth part fitted into both ends of a trunk part formed into a rectangular tube shape to the trunk part.

Next, the operation of each part of the container manufacturing apparatus will be described in detail, following the flow of two container bodies 1 that are successively supplied from the body magazine 43.

First, the two magazines 43 of the trunk supply device 15
Prior to operation of the container manufacturing apparatus, a large number of container bodies 1 are filled by manual operation, and bodies 1 are similarly replenished as needed during operation. Torso 1
are folded twice and stored in layers between the stopper 58 on the left side of FIGS. At the same time, movement of each trunk 1 in the width direction is prevented by the guide round bars 56 on both sides. Further, the rotating end of the push plate 64 of the movable body 61, which is biased to the left by the spiral spring 67, comes into pressure contact with the right end surface of the body 1 in the magazine 43 and pushes them to the left. Both end portions of the left end body portion 1 are pressed against the convex portion 57 of the stopper 58.
Then, as will be described later, each time the body parts 1 in each magazine 43 are taken out one by one starting from the leftmost one, the body part 1 in the magazine 43 is pushed by the moving body 61.
It gradually moves to the left along the guide rail 52 and the guide round bar 56. To put the trunk 1 into the magazine 43, hold the handle 316 of the moving body 61 with your hand and move it to the right, and then put the trunk 1 into the left side of the moving body 61. After the body 1 is placed on the right side of the body 61, the moving body 61 may be moved to the right side of the body 1 by holding the body 1 by hand. In the latter case, when the movable body 61 is moved to the right, the inner surface of the push plate 64 hits the side edge of the body 1, but this causes the push plate 64 to rotate outward against the force of the spring 65. Therefore, the movable body 61 passes the newly inserted trunk 1 and moves to the right side thereof. and,
When the movable body 61 moves to the right side of the body 1, the push plate 64 returns to the inside by the spring 65. When you release your hand from the movable body 61 in this state, the force of the spiral spring 67 causes the push plate 64 to return to the inside. The rotating end comes into pressure contact with the body 1 at the right end.

It rotates to the retracted position c and 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 55 rotates clockwise from the retracted position c. After the trunk 1 reaches the fixed guide 44 and leaves the trunk removal arm 46, it reaches the guide position b and the trunk 1 is sandwiched between the fixed guide 44 and the holder 21 rotates again. Stop at this position b until you start. Furthermore, when the stopped holder 21 starts to rotate, the lifter 47 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 clockwise from the retraction position c. Before it starts rotating,

Lifter 47
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, as the lifter 47 rises, the body 1 folded twice
Both ends of the body 1 fit into the bottoms 32 of the recesses of the fixed clamp member 29 and the movable clamp member 30 of the holder 21 from below, and the body 1 fits into the recesses of the two sets of guides 44, 45 and the clamp members 29, 30 of the holder 21. bottom of place 3
2 will guide you up. Then, when the lifter 47 reaches the upper end position d, the body 1 is moved to the guide 4.
4, 45 apart from the clamp member 2 of the holder 21.
The holder 21 is inserted between the bottoms 32 of the recesses 9 and 30, and then the holder 21 rotates and moves to the trunk opening 40 while holding the two double-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 77 . That is, the trunk opening device 7
The pusher 78 of No. 7 is in the advanced position when the holder 21 starts to rotate, and while the holder 21 is rotating, moves to the retracted position farthest from the holder 21 as shown in FIG. When the pusher 78 stops at the trunk opening 40, the roller 38 of the holder 21 comes into contact with the pusher 78 in the retracted state.
The mutual distance between the fixed clamp member 29 and the movable clamp member 30 of the holder 21 is
It is almost the same as when it is fully open. On the other hand, the upper and lower vacuum suction cups 79 of the body opening device 77
is stopped at a retracted position vertically farthest from the holder 21 from a little after the holder 21 starts rotating until a little before the holder 21 stops. The operation of the upper and lower suction cups 79 is vertically symmetrical, so the following operation description will be given only for the upper suction cup 79 (see FIGS. 13 to 15). When the upper suction cup 79 is in the retracted position at the upper end, the second elevating body 86 has moved upward away from the stopper 87, 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. Therefore, 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, thereby opening the pair of suction cups 79 and creating a predetermined gap between them. There is. Shortly before the holder 21 stops, the horizontal drive shaft 93 of the suction cup 79 starts to rotate, causing the fixed lever 94 fixed thereto to rotate clockwise in FIG. 13. The fixed lever 94 rotates the rotating lever 95 in the same direction via the connecting member 97 and the connecting recess 98, and the rotating lever 95 lowers the first elevating body 84 via the drive rod 92. let As the first elevating body 84 descends, the second elevating body 86 moves to the first elevating body 84.
As well as descending while maintaining the maximum distance between
The pair of suction cups 79 descend in an open state and enter between the fixed clamp member 29 and the movable clamp member 30 of the stopped holder 21, and eventually the second elevating body 86 hits the stopper 87 and stops. do. Second
When the 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 79 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 link 9
0, the upper ends of the pair of doglegged links 91 are rotated in the direction away from each other, so that the pair of suction cups 79 close and suction both sides of the body 1. Suction cup 7
9 closes, the drive shaft 93, that is, the first elevating body 84 stops, and a little later, the drive shaft 93 moves to the first
By rotating counterclockwise in FIG. 3, the first elevating body 84 starts to rise, and at the same time, the pusher 78 starts to move forward. As the first elevating body 84 rises, the vertical distance between it and the second elevating body 86 gradually increases, the suction cup 79 opens, and both sides of the doubly folded body 1 move away from each other. Being pulled. At the same time, the movable clamp member 30 of the holder 21 is pushed by the pusher 78 and approaches the fixed clamp member 29, so that the body 1 is expanded into a diamond shape. In this way, both sides of the doubly folded body part 1 are pulled to both sides by the suction cup 79 and both ends are pushed by the clamp members 29 and 30 to open the body part 1. Unlike when pressing with the clamp members 29 and 30,
There is no possibility that the body part 1 will bend to one side in a dogleg shape. The pusher 78 moves to the extension end and the trunk 1
When the opening is completed, the suction cup 79 stops operating and releases the body 1, and soon the two elevating bodies 84, 86
The vertical distance between them becomes maximum, and these rise to the retracted position at the upper end with the suction cup 79 open. Immediately before the suction cup 79 returns to the retracted position, the rotating body 20 begins to rotate, and the holder 21 holding the opened body 1
The roller 38 moves from the pusher 78 stopped at the advanced position to the cam 112, and moves along the cam 112 to the body bent portion 41. 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, in the event that the upper suction cup 79 collides with the holder 21 etc. when moving up and down,
If the rotating lever 95 continues to rotate as it is, the device will be damaged. However, in the case of this opening device 77, when 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 97 of the rotating lever 95 becomes fixed. It is pushed by the lever 94 and disengages from the coupling recess 98, thereby causing the fixed lever 9 to
4 and the rotating lever 95 are separated. Rotating lever 9
The fixed lever 94 separated from 5 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, and the device is stopped and the device is rotated as necessary. An alarm is issued. Therefore, the suction cup 79
This prevents damage to the device due to collisions, etc. The same applies to the lower suction cup 79 and the lifter 47 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 pusher 101 of the trunk folding device 100 is in the eighth position.
As shown in the figure, the roller 3 of the holder 21 has stopped at the retracted position and has moved from the body opening 40.
8 moves from the cam 112 to the pusher 101 and stops. 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 holder 2.
One movable clamp member 30 gradually approaches the fixed clamp member 29. The movable clamp member 30 is
As shown by the solid line in FIG. 18, the fixed clamp member 2
The body 1 moves to the position where the body 1 and the mandrel 102 are sandwiched between the clamp members 29 and 9, that is, the position where the holder 21 is completely closed, and then stops. 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 35 of each clamp member 29, 30 and the corresponding vertical surface. The folded portion 9 is formed by strongly sandwiching the folded portion 9 between the two portions 33 and 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 The clamp members 29, 3 will expand slightly as before bending.
It is held close to 0. 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 the cam 113
It moves along to the trunk transfer section 42. In addition, in the event that the mandrel 102 collides with the holder 21 or the like while moving up and down, a safety device is activated in the same way as in the case of the suction cup 79 of the body opening device 77.

The container body 1 that has been moved to the body transfer unit 42 is transferred from the holder 21 of the body forming device 14 to the holder 116 of the container assembly device 16 by the body transfer device 17 . That is, the rotating body 20 of the trunk forming device 14
The rotary body 115 of the container assembly device 16 rotates and stops at the same time, and the holder 21 of the body forming device 14 holding the bent body 1 moves to the body transfer section 4.
At the same time, the empty holder 116 of the container assembly device 16 stops directly below the guide 142. The pusher 185 provided on the container assembly device 16 of the trunk transfer section 42 is
When the holder 116 starts to rotate, it is stopped at the closed position g closest to the holder 116, as shown by the chain line in FIG. 11
6 to the farthest open position. 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,
The holder 21 of the trunk forming device 14 also
When it stops at 2, it is slightly open compared to the fully opened state. Pusher 14 of trunk transfer device 17
4 is stopped at the upper end retracted position farthest upward from the holder 21 of the body forming device 14, as shown by the solid line in FIG. 21,1
16 starts descending slightly before stopping, and the body part forming device 14 in the stopped state is moved between the clamp members 29 and 30 of the holder 21 and between the block 1 of the guide 142.
49 and 150, and descends to the lower end position immediately above the holder 116 of the container assembly device 16. At this time, the short sides 165 at the four corners of the pusher 144 are connected to the grooves 36 on the vertical surfaces 33 and 34 of the holder 21 and the grooves 155 on the guide surfaces 152 and 153 of the guide 142.
the upper end of the side surface of the body part 1 facing these grooves 36, 155 is pushed downward, whereby the body part 1 is moved from the holder 21 of the body part forming device 14 to the guide 1.
42 to the holder 116 of the container assembly device 16. Trunk stopper 14 of trunk transfer device 17
3 is stopped at the lower end retracted position as shown by the solid line in FIG. 23 while the holders 21 and 116 are rotating, and when the holders 21 and 116 are stopped and the body 1 is lowered to a certain extent, the container is The assembly device 16 is raised to the upper end operating position immediately below the holder 116 and stopped. Then, as described above, the container assembly device 16
The body 1, which has been transferred to the holder 116, 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, before the holders 21 and 116 begin to rotate, 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. and,
The holder 116 holding the body 1 moves from the pusher 185 in the closed position g to the cam 181, and the cam 18
1 to the bottom/mouth supply section 135. In addition, in the event that the pusher 144 of the trunk transfer device 17 is raised or lowered, the holders 21, 116 and the guide 1
42, etc., the safety device is activated in the same manner as described above.

At the bottom and top ends of the container body 1 that has been moved to the bottom and mouth supply section 135 of the container assembly device 16,
The container bottom 2 and the container mouth 3 are fitted by the mouth supply device 192 . That is, the pusher 187 of the bottom/mouth supply section 135 is connected to the holder 116.
When the holder 116 starts to rotate, it is stopped at the closed position b closest to the holder 116 as shown by the chain line in FIG. 19, and while the holder 116 is rotating, the first
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 187 in the open position and stops, and at this time the holder 116 is slightly opened from the completely closed state. Holder 1 at this time
The opening degree of 16 is the same as the opening degree of the holder 116 when the pusher 185 in the trunk transfer section 42 is closed. When the holder 116 starts rotating, the upper and lower lifting tables 196, 195 of the bottom/mouth supply device 192 are stopped at the retracted positions furthest vertically from the holder 116. Moving stopper 21
7,226 is about to close. Also, the stopper 2 of the mouth chute 194 and the bottom chute 193
08 is the 31st while the holder 116 is stopped.
It is in the operating position as shown by the solid line in the figure, and the chute 194, 1 is opened by hooking the leading mouth part 3 and bottom part 2.
It is stopped on 93. And the holder 116
Before and after the start of rotation, the stopper 208
Rotate to the non-operating position 1 as shown by the chain line in the figure,
Release the top mouth part 3 and bottom part 2 and open the chute 1.
After being sent out from 94, 193, it returns to the operating position again. The mouth portion 3 and bottom portion 2 sent out from the chute 194, 193 are inserted into the holes 213, 22 of the elevating table 196, 195 that is stopped at the retracted position.
2, the moving stopper 217 in the closed state,
226 and stopped. Mouth chuck 19
8 and the bottom chuck 197 are at the retracted position vertically farthest from the holder 116 when the mouth part 3 and the bottom part 2 are sent out from the chute 194, 193 to the lifting table 196, 195 while the holder 116 is rotating. The bottom chuck 198 is open and the bottom chuck 197 is closed (see FIG. 39A). Then, the mouth part 3 and the bottom part 2 are sent out to the lifting tables 196, 195 and the chute 19
After the stopper 208 of 4,193 returns to the operating position, the mouth chuck 198 begins to descend in an open state and the bottom chuck 197 begins to rise in a closed state. Then, a little before the holder 116 stops, the upper and lower chucks 198 and 197 stop at the intermediate position, the mouth chuck 198 closes and grips the cylindrical part on the upper side of the mouth 3 from the outside, and the bottom chuck 197 opens and the bottom 2 Horizontal collar part 1 at the lower end
Grasp the inner peripheral surface of 0 from the inside. Upper and lower chuck 19
After 8,197 grabbed the mouth part 3 and the bottom part 2,
As the movement stoppers 217 and 226 of the upper and lower lifting tables 196 and 195 open, one of the two mouth chucks 198 and the two bottom chucks 1
97 rotates one mouth portion 3 and bottom portion 2 by 90 degrees together with the horizontal rotating disk 317 and then stops. The rotation of these chucks 198 and 197 is
The protrusions 13 and 11 of the mouth part 3 and the bottom part 2
This is necessary in order to match the folded portion 9 of the body 1 held at the holder 16. That is, when the mouth part 3 is fed by the chute 194, the two protrusions 1 of the mouth part 3
However, as shown in FIG. 32, since the two mouth chute 194 form a right angle when viewed from the plane, the two mouth parts sent from the chute 194 into the hole 213 of the upper lifting table 196 The protrusions 13 of part 3 are not aligned in the same direction, and are 90 degrees apart from each other.
It's off by ゜. 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 There is always a 90° deviation from the Therefore, by rotating this mouth part 3 by 90 degrees, the folded parts 9 and 2 of the two body parts 1 can be folded together.
The protrusions 13 of the two mouth portions 3 match. The same applies to the bottom portion 2. Next, check the upper and lower chucks 198,
197 finishes rotating, the upper elevating table 196 and mouth chuck 198 begin to descend, and the lower elevating table 195 and bottom chuck 197 begin to rise. and stop downwards, respectively. At this time, the lower part of the guide plate 216 of the upper elevating table 196 and the upper part of the guide plate 224 of the lower elevating table 195 enter into the body 1 from above and below. When the upper and lower lifting tables 196, 195 stop, the pusher 187 moves to the closed position b to further reduce the opening degree of the holder 116. Vertical lifting table 19
6,195 stops, the mouth chuck 198 further descends and the bottom chuck 197
is raised, whereby the mouth portion 3 and the bottom portion 2 are guided by the guide plates 216, 224 and fitted into the upper and lower ends of the body portion 1 (see FIG. 39B). At this time, the guide plates 216 and 224 act like shoehorns, and the mouth part 3 and the bottom part 2 fit smoothly into the body part 1. The mouth part 3 and the bottom part 2 are the body part 1
When the upper elevating table 196 starts to rise, the lower elevating table 195 starts to descend, and eventually these elevating tables 196,
195 reaches the retracted position and stops. When the elevating tables 196, 195 move up and down, the mouth 3 and bottom 2 are gripped by the chucks 198, 197, so the guide plates 216, 224 move up and down from between the mouth 3 and bottom 2 and the body 1. (See Figure 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
7 stops, and eventually the mouth chuck 198 opens, releases the mouth 3, and rises, and the bottom chuck 197 closes, releases the bottom 2, and then descends. 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 the body portion 1 is moved to the pusher 18 in the closed position h.
7 to the cam 182 and moves along the cam 182 to the first joint 136. When the holder 116 starts to rotate, the movement stoppers 217 and 226 of the upper and lower lifting tables 196 and 195
is closed, and the upper and lower chuck 1 are turned while the holder is rotating 116 times.
98 and 197 return to the retracted position. Next, the mouth part 3 is added to the body part 1 which has stopped at the bottom part/mouth part supply part 135.
and when feeding the bottom part 2, one of the mouth chucks 198 and one of the bottom chucks 197 are rotated 90 DEG in the opposite direction.

The body 1 moved to the first joint 136 and the bottom 2 and the mouth 3 fitted thereto are joined together by a joining device 285. That is, the pusher 188 of the first joint 136 is
When the holder 116 starts to rotate, it is stopped at the closed position j closest to the holder 116 as shown by the dashed line in FIG. 19, and while the holder 116 is rotating, it moves to the open position furthest from the holder 116 as shown by the solid line in FIG.
The sixth roller 134 is in the open position.
When the holder 116 is rotated, it stops in contact with the bottom-mouth pressing device 258, and at this time the holder 116 is slightly open 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 187 is closed in the bottom-mouth supply section 135. When the holder 116 is rotating, as shown in FIG.
The piston rod 265 of the cylinder 264 is in the retracted position, and the holder pushing rod 267 pushes the holder 116.
The upper and lower linear cams 268 and 269 are moved to the outermost positions (right side in FIG. 40).
4 are the cam grooves 27 of these cams 268 and 269
0,271, and the upper and lower pressing members 27
6, 282 is stopped at the retreat position which is the furthest from the holder 116 in the vertical direction.
After the piston rod 265 of the cylinder 264 is advanced, the holder pressing rod 26
As the upper and lower linear cams 268, 269 move inward, the upper and lower pressing members 276, 282 move upward and downward along the cam grooves 270, 271, respectively, and the forces of the springs 278, 283 push the mouth 3 and bottom 2 until they are completely fitted into the body 1.
At the same time, the holder pressing rod 267 pushes the holder 116
The moving body 124, i.e., the moving clamp member 125
The holder 116 is pushed inward to completely close the holder 116, and then the pusher 188 moves to the closed position j. On the other hand, when the holder 116 stops, the joining device 285
A high-frequency power supply is supplied to the high-frequency heating coil 1 through the primary coupling coil 256 and the secondary coupling coil 132.
A high frequency current is supplied to the holder 116, which heats the holder 116 and bonds the mouth 3 and the bottom 2 to the body 1. When the first bonding is completed in this manner, the piston rod 26 of the cylinder 264 is
After the holder pressing rod 267, the mouth pressing member 276 and the bottom pressing member 282 return to their retreat positions, the holder 116 rotates and moves from the pusher 188 in the closed position j to the cam 183, and the cam 1
83 to the second joint 137.

The holder 116 that has been moved to the second joint portion 137 is completely closed, and the body portion 1, bottom portion 2, and mouth portion 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 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 137.

The container A that has been moved to the discharge section 139 is discharged by the container discharge device 18. That is, the holder 11
6 begins to rotate, the pusher 186 of the ejector 139 is stopped at the open position farthest from the holder 116, as shown by the solid line in FIG. It moves to the closed position k closest to the holder 116, as shown by the chain line. 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. Timing screw 2 of container discharge device 18
92 stops shortly after the holder 116 stops, thereby positioning the empty container container 291 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 pushing device 293 is at the upper end retracted position 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. This results in
The completed container A is transferred from the holder 116 to the recess 294 of the container 291 that is stopped directly below it, and the pusher 301 rises again and returns to the upper end retracted position when the holder 116 begins to rotate. In addition, the timing screw 292 rotates after the completed container A is transferred to the container 291 until shortly after the holder 116 rotates and stops again, ejecting the container 291 containing the completed container A and discharging the container 291 containing the completed container A. The empty container 291 is carried into the discharge section 139. Then, the container 291 containing the complete container A is discharged by the conveyor 290. In addition, in the event that the pusher 301 of the container pushing device 293 collides with the holder 116 or the like while ascending or descending, the connecting piece 310 of the fixed lever 305 will rotate as in the case of the suction cup 79 of the body opening device 77. When the lever 312 is disengaged from the coupling recess 314, 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, the body forming device 1
