Abstract

PROBLEM TO BE SOLVED: To always simply and certainly take out the pour spout forming member of an article-containing bag to the outside from the pour spout taking- out opening of a box. SOLUTION: When BIB is produced by allowing an article-containing bag 2 having the pour spout forming member 4 provided to a bag main body 3 to fall almost downwardly from the vicinity of a predetermined bag falling position to house the same in a box 31, the pour spout forming member 4 of the article-containing bag 2 moved from the upstream side is held by a pour spout stop mechanism 172 to bring the article-containing bag 2 to an almost suspended state temporarily in the vicinity of the predetermined bag falling position. Since the article-containing bag 2 can be arranged in the box 31 in such a state that the posture thereof is almost constant with respect to the box 31, the pour spout forming member 4 of the article-containing bag 2 can be always simply and certainly taken out to the outside from the pour spout taking-out opening of the box 31. Further, there is no possibility of the damage to the box 31 even if a large impact is applied to the box 31 when the article- containing bag 2 falls into the box 31 from almost above.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box by dropping an article-containing bag having a bag body for accommodating articles and a spout forming member provided on the bag body from near a predetermined bag drop position. The present invention relates to a BIB manufacturing apparatus and method for manufacturing a BIB by storing it in a BIB. The BIB is an abbreviation of “bag in box (bag in a box)”, in which a bag with an article containing a liquid such as drinking water and other articles is stored in a cardboard box or another box. .

[0002]

2. Description of the Related Art Conventionally, a continuous bag 1 as shown in FIG.
4B and FIG. 6 using a box 31 as shown in FIGS. 4A and 5 and a continuous bag-filled BIB manufacturing apparatus (hereinafter referred to as “conventional BIB manufacturing”). Devices) are known. The BIB is
As shown in FIG. 4 (b), the article bag 2 (hereinafter, referred to as “liquid bag”) shown in FIG. 2 in which liquid such as drinking water and other articles are filled or accommodated is shown in FIG. ) Is stored in a cardboard box as shown in FIG. Then, the bag body 3 of the bag 2 is usually provided as shown in FIG.
As shown in FIG. 7, a spout forming member 4 including a spout member 6 and a cap member 9 is attached. In addition, the said spout is a katakana notation of "spout",
Means the sink.

As shown in FIGS. 4 (b) and 6, the box 31 usually has openings 38, 4 for taking out a spout for pulling out the spout forming member 4 from the box 31 to the outside.
1 is provided. In addition, as shown in FIG.
Are used in the form of a continuous bag body 1 formed to be continuous with each other in a longitudinal shape. The configuration of the bag 2, the bag continuum 1, the liquid bag 2, the box 31, and the BIB is described in the section “Embodiments of the invention” in “Description of bag continuum and box (FIGS. 1 to 6)”.
This will be described in detail in the section.

In the conventional BIB manufacturing apparatus, the most downstream bag 2 of the continuous bag body 1 pulled out from the upstream side to the downstream side by the bag feeding mechanism from the stocker for the continuous bag body 1 is a bag body. The spout 3 is guided into the liquid filling mechanism while being guided by a pair of left and right guide rails.
After the cap member 9 is removed from the spout member 6 by the liquid filling mechanism, the bag 2 is filled or accommodated with an article such as a liquid through the central opening 20 of the spout member 6 to become the liquid-containing bag 2, Next, the cap member 9 can be attached to the spout member 6 again.

Next, in the conventional BIB manufacturing apparatus, the liquid-containing bag 2 moves on the bag transfer roller conveyor inclined downward from the upstream side to the downstream side by its own weight toward the downstream side. The spout forming member 4 of the next bag 2 connected to the upstream side of the liquid bag 2 is held near a predetermined liquid filling position by the liquid filling mechanism, so that it is held near a predetermined bag separating position. . Then, since the bag 2 with liquid is separated from the next bag 2 by the blade of the bag separating mechanism, it moves further downstream on the roller conveyor by its own weight, and is moved to the shutter plate of the bag body stopping mechanism. The bag body 3 once stops on the roller conveyor by contact. The bag between the liquid bag 2 and the next bag 2 (in other words, between the bag body 3 of the liquid bag 2 and the bag body 3 of the next bag 2) is separated by the blade of the bag separating mechanism. Sometimes, if there is a pair of left and right guide rails for guiding the spout forming member 4, the cutting tool comes into contact with the guide rail before contacting the bag continuous body 1, which hinders the separation. The guide rail terminates upstream of the predetermined bag separation position. In other words, the guide rail is provided only up to the upstream side of the bag separating position of the bag continuum 1 by the blade.

Next, in the conventional BIB manufacturing apparatus, as described above, the liquid-containing bag 2 once stopped on the roller conveyor due to the contact of the bag body 3 with the shutter plate of the bag body stopping mechanism, the shutter plate is raised. Then, the roller conveyor again moves toward the downstream side by its own weight, and then falls almost downward from near the downstream end of the roller conveyor (that is, near the bag dropping position). In addition, the bag 2 containing the liquid, during the process of falling,
After its position and / or shape is regulated as required by the shooter bucket, it is stored in a box 31 waiting substantially below it. Then, the bag-containing box 31 is sent to the next step by the box-conveying roller conveyor, and the next box 31 for the next liquid-containing bag 2 is sent by the roller conveyor to almost below the bag dropping position. It is.

[0007] Since the above-described steps for producing the BIB are repeatedly performed in the same manner on the succeeding bag 2 of the bag continuous body 1 in the same manner, substantially constant time intervals (for example, approximately 3 minute intervals) are used. ), BIB can be sequentially obtained.

[0008]

However, the conventional BIB
According to the manufacturing apparatus, although the bag 2 with liquid is temporarily stopped on the roller conveyor by bringing the bag body 3 into contact with the shutter plate of the bag body stopping mechanism, the shutter plate is opened again thereafter. The liquid bag 2 moves on the roller conveyor to the downstream side by its own weight, and falls almost downward from the downstream end of the roller conveyor. In this dropping process, the position and / or shape of the liquid bag 2 is regulated by the shooter bucket as necessary. However, the position of the spout forming member 4 is substantially regulated. Not
It is stored inside the box 31 waiting almost below it.

Accordingly, the liquid-containing bag 2 housed in the box 31 in this manner is provided with an opening forming mechanism 33 in which the spout forming member 4 forms the openings 38, 41 for taking out the spout of the box 31. It is not always stored in the box 31 in a state of being always adjacent to the box 31. For this reason, when it is desired to pour out the liquid in the liquid bag 21 to the outside, the spout forming member 4 of the liquid bag 2 stored in the box 31 is searched for, and the spout forming member 4 is placed in the box 31. The operation of pulling out the spout take-out openings 38 and 41 of the opening forming mechanism 33 is very troublesome. Therefore, the spout forming member 4 of the liquid-containing bag 2 which falls almost downward from the downstream end of the roller conveyor and is housed in the box 31 is filled with the liquid containing the liquid which is slightly separated from the opening forming mechanism 33 of the box 31. When the bag 2 is stored in the box 31, the worker manually adjusts the position of the heavy bag 2 in the box 31 to form the spout of the bag 2. Member 4
Is made adjacent to the opening forming mechanism 33 of the box 31, so that the operation is troublesome.

The bag 2 containing liquid moves on the roller conveyor even if it is a short distance, and falls almost downward in a state of momentum, and passes through the box 31 through the shooter bucket.
Since the box 31 is housed inside the box 31, a large impact is likely to be applied to the box 31, and the box 31 may be damaged.

[0011]

Further, the shutter means of the bag body stopping mechanism is brought into contact with the bag body of the article-containing bag on the upstream side from the vicinity of the predetermined bag dropping position to temporarily move the article-containing bag to the downstream side. It is preferable to prevent it.

Further, after a plurality of bags are connected to each other in a bag continuous body formed in a longitudinal shape and connected to each other in the vicinity of a predetermined article storing position by an article storing mechanism, these bags containing the articles are removed. The article-containing bag is produced by sequentially separating the bag from the bag continuum by the blade of the bag-separating mechanism near the predetermined bag-separating position, and the spout forming member of the article-containing bag is at least the predetermined shape of the article accommodating mechanism. Guided by a guide rail from the vicinity of the article storage position to the vicinity of the predetermined bag dropping position of the spout stop mechanism, the movable rail portion of the guide rail is moved forward to its relief position, and then the It is preferable to make the cutting tool perform the separating operation.

The shooter bucket 74 has a substantially rectangular parallelepiped box-shaped frame 75 having an open top and bottom, and a receiving plate 76 formed by projecting a downstream side plate of the frame 75 substantially upward. May be provided. Also, shooter bucket 7
4, a pair of left and right side plates of the box-shaped frame 75 (that is,
It is preferable that the pair of side plates that are substantially parallel to the paper surface of FIG. 7 be divergently inclined from the lower end toward the upper end.
In this case, the liquid bag 2 inserted into the frame 75 from the upper end opening of the frame 75 is sandwiched in the lateral width thereof, and then stored in the box 31 to have a substantially rectangular parallelepiped shape (for example, , Almost cubic shape). Also, when the box 31 is in the raised position, the lower end of the frame body 75 is inserted into the four lid pieces 32a to 32d in the upright state of the box 31, so that the liquid-containing bag 2 holds the frame by its own weight. It passes through the body part 75 and falls smoothly into the box 31.

The liquid-containing bag 2 suspended in the air as described above is released from the suspended state by the bag stopping mechanism 68 after an appropriate time elapses.
Receiving plate portion 76 and frame portion 75 of shooter bucket 74
After passing through the inside of the frame portion 75 while its position and / or shape is regulated as necessary, it is stored in the box 31 at the ascending position. Next, the box 31 is lowered from the raised position to the lowered position, and then sent to the next step by the roller conveyor 72 for transferring the box. Since the upper surface opening 42 of the box 31 is closed by the four lid pieces 32a to 32d, the box 31 shown in FIG.
IB (that is, the liquid bag 2 stored in the box 31) is obtained.

The above-described steps for manufacturing the BIB are repeated in the same manner for the subsequent bag 2 in the same manner, so that the BIB is formed at substantially constant time intervals (for example, at intervals of about 3 minutes). Can be obtained sequentially.

When the spout forming member 4 of each bag 2 of the bag continuum 1 has almost reached a predetermined liquid filling position substantially below the liquid injection nozzle 66 and the chuck member 106, the liquid filling mechanism 64 The apparatus further includes a spout positioning mechanism 121 for stopping the spout forming member 4 near the predetermined liquid filling position. As shown in FIG. 12, the spout positioning mechanism 121 has a positioning member 123 formed of a lever plate whose substantially middle portion is rotatably supported on a first base 53 by a shaft 122.
It has. One end of the positioning member 123 is connected to a driving means 12 such as an air cylinder for reciprocatingly rotating the positioning member 123 about the shaft 122 as a fulcrum.

On the upstream side near the other end of the positioning member 123, a concave portion 127 for engaging the spout forming member 4 of each bag 2 of the continuous bag body 1 is provided. Further, a recess regulating plate 128 for regulating the shape of the recess 127 is rotatably attached to the positioning member 123 by a shaft 129. Then, the recess regulating plate 1
12 is elastically urged counterclockwise in FIG. 12 with the shaft 129 as a fulcrum by an urging means 130 such as a coil spring. It is held in the moving position.

Almost below the predetermined liquid filling position,
The pressing rod 131 of the outside air intrusion prevention mechanism 65 is arranged. The pressing rod 131 is connected to a piston 133 of a driving unit 132 such as an air cylinder attached to the first base 53, as shown in FIG.

Next, the operation of the bag feeding mechanism 63 and the liquid filling mechanism 64 configured as described above will be described.

When the BIB manufacturing apparatus is started, the operator pulls out the bag 2 on the most downstream side (that is, the most distal side) of the continuous bag body 1 in the stocker 54a to the vicinity of the second pushing member 92. In this case, the operator, while the sheet-shaped bag body 3 of the most downstream bag 2 passes between the guide rail 55 and the horizontal guide plate 61, and the ring-shaped lower part of the spout forming member 4 of the bag 2 With the pair of left and right guide rails 55 engaged with the side grooves 12 (see FIG. 3 (a)), the spout forming member 4 passes between the pair of left and right guide rails 55 and returns to the position shown in FIGS. The first push member 81 in the moving position is slightly downstream.

Next, when an operation switch (not shown) is turned on, the first pushing member 84 is driven downward from the dashed line position to the solid line position in FIG. 2 is driven from the solid line position in FIG. 10 to the two-dot chain line position (in other words, from the solid line position in FIG. 12 to the one-dot chain line position). Therefore, the spout forming member 4 of the bag 2 engages with the concave portion 83 of the first pushing member 84 and moves from the position 4a in FIG.
Move to the downstream side to the position b. In this case, the spout forming member 4 and the first pressing member 84 are connected to the second pressing member 92.
Since the second pressing member 92 comes into contact with the curved surface of
The counterclockwise rotation in FIG. 12 is performed in the counterclockwise direction in FIG. 12 against the urging force of the urging means 99 with the shaft 96 as a fulcrum.

When the spout forming member 4 is brought to the position 4b in FIG. 12 by the first pushing member 84, the first pushing member 84 is driven upward by the driving means 85, so that the second pushing member 84 is driven. The push member 92 of FIG. 12 is rotated backward by the biasing force of the biasing means 99 and returns to the return rotation position indicated by the solid line in FIG. The first pushing member 84 is driven by the second driving means (not shown) to return to the position indicated by the dashed line in FIG. 10 in order to perform the same process on the subsequent bag 2.

Next, the second pushing member 92 is driven by the driving means 9.
3 drives from the solid line position in FIG. 12 to the two-dot chain line position (in other words, from the one-dot chain line position to the solid line position in FIG. 11). Therefore, the spout forming member 4 of the bag 2 is engaged with the concave portion 91 of the second pressing member 92, and 4b in FIG.
From the position to the position 4c. The spout forming member 4 of the bag 2 is connected to the second pressing member 92.
The spout positioning mechanism 121 of the liquid filling mechanism 64
Is pressed against the recess 127 of the positioning member 123,
It engages with this recess 127.

When the spout forming member 4 of the bag 2 is moved from the position 4a to the position 4c (ie, near the predetermined liquid filling position) via the position 4b in FIG. Also moves downstream by almost the same distance. Further, with the movement of the bag 2, each bag 2 of the continuous bag body 1 connected to the upstream side of the bag 2 is sequentially sent out from the stocker 54a and automatically moves toward the downstream side.

When the spout forming member 4 of the bag 2 comes to the position 4c from the position 4a in FIG. 12, the chuck member 106 is located almost above the spout forming member 4, as shown in FIG. At the same time, the pressing rod 131 of the outside air intrusion prevention mechanism 65 is located substantially below. Then, the pressing rod 131 is driven upward by the driving means 132, and presses the vicinity of the lower end of the center opening 20 of the spout member 6 from below the bag 2 via the lower sheet material 3b (see FIG. 3). The outside air is prevented from entering the inside of the bag body 3 from the central opening 20.

Next, the chuck member 106 is driven downward by the driving means 105 to chuck the cap member 9 of the spout forming member 4.
5 driven upwards. Accordingly, since the cap member 9 is pulled upward by the chuck member 106 with a strong force, the cap member 9 is removed from the spout member 6. Then, since the movable member 102 is driven downstream by the driving means 107, the liquid injection nozzle 66 and the chuck member 106 move downstream from the position shown in FIG. 8 to the position shown in FIG.

Next, the liquid injection nozzle 66 is driven downward by driving means (not shown) to engage with the upper end of the central opening 20 (see FIG. 3B) of the spout member 6 of the bag 2. You. For this purpose, the center opening 2 of the spout member 6 is
Since the liquid injection nozzle 66 prevents the outside air from entering the inside of the sheet-shaped bag body 3 from 0, the pressing rod 1
31 is driven downward by the driving means 132.

Next, the liquid injection nozzle 66 jets a liquid such as drinking water from its tip, so that the liquid is filled into the bag body 3 through the central opening 20 of the spout member 6. Then, when a substantially predetermined amount of liquid is filled in the bag body 3, the liquid injection nozzle 66 is raised and the movable member with the liquid injection nozzle 66 and the chuck member 106 is moved, just opposite to the above-described operation. With the return of the member 102,
The lowering and raising of the chuck member 106 are performed respectively. The chuck member 106 engages the cap member 9 with the spout member 6 of the bag 2 at the time of the downward movement, and releases the chucking of the cap member 9 at the time of the upward movement.

Next, the second pushing member 92 also moves to the backward position just opposite to the operation at the time of forward movement. In addition,
The second pressing member 92 is configured such that the spout forming member 4 of the bag 2 is 4c.
, The chuck member 106 is moved to the position of the cap member 9.
May be moved to the return position at any time until the spout member 6 of the bag 2 is completely fitted.

Further, when the chuck member 106 begins to ascend after the cap member 9 has been fitted into the spout member 6 of the bag 2, the positioning member 123 is driven by the driving means 124 and the shaft 122 is used as a fulcrum, and the solid line in FIG. From the position to the dashed line position. In this case, the recess regulating plate 128 is turned against the urging means 130 with the shaft 129 as a fulcrum as necessary so that the spout forming member 4 of the bag 2 can always be smoothly separated from the recess 127 of the positioning member 123. Twelve clockwise rotations.

Since the bag 2 is filled with a substantially predetermined amount of liquid inside the bag body 3, the bag 2 greatly expands on the roller conveyor 62 which is inclined downward from the upstream side to the downstream side.
Therefore, when the bag 2 is released from the position regulation by the positioning member 123, the roller conveyer 6 by its own weight.
2 Move up. When the bag 2 is moved, the pair of left and right guide rails 55 are engaged with the ring-shaped lower groove 12 of the spout member 6 of the bag 2. The guide rail 55 moves. The movement of the bag 2 continues until the spout forming member 4 of the next bag 2 immediately following the upstream side is positioned by the positioning member 123 in the same manner as described above. As a result, as shown in FIG. 7, the first bag 2 reaches the vicinity of the blade support member 141 of the bag separating mechanism 67 (that is, the vicinity of a predetermined bag separating position) and stops.

For subsequent bags 2 after the next bag 2,
When the liquid bag 2 on the downstream side moves to the vicinity of the bag separating position, usually, the next bag 2 is pulled by the liquid bag 2 on the downstream side so that the spout forming member 4 causes the predetermined liquid. Automatically moves to near the filling position.
Therefore, the pushing operation by the first pushing member 84 and the second pushing member 92 usually does not function very much on the spout forming member 4 of the succeeding bag 2, and the downstream liquid-containing bag does not function. Next bag 2 that is automatically moved by being pulled by 2
Only when the operation of the spout forming member 4 is not carried out smoothly does it function effectively as in the case of the bag 2 on the most downstream side.

Conventionally known continuous bag filling type BIB
In the manufacturing apparatus, the guide rail 55 terminates on the upstream side of the blade support member 141 so that the guide rail 55 does not interfere when the blade 144 is lowered to separate each bag 2 of the bag continuum 1. ing. But,
In the continuous bag filling type BIB manufacturing apparatus according to the present embodiment, the guide rail 55 extends to near the upper part of the roller conveyor 72 for box movement with the improvement of the bag stopping mechanism 68. To this end, the guide rail 55 has a movable rail portion 55a near the bag separating mechanism 67,
An upstream fixed rail portion 55b and a downstream fixed rail portion 55c are provided upstream and downstream of the movable rail portion 55a, respectively. And
Normally, between the movable rail portion 55a and the upstream fixed rail portion 55b, both ends are abutted against each other. Further, the downstream fixed rail portion 55 is vertically displaced from the movable rail portion 55a, and is located at a position higher than the movable rail portion 55a. While being superimposed on each other, these adjacent ends are slightly separated from each other in the vertical direction.
The separated distance is substantially equal to the distance between the intermediate groove 22 and the lower groove 12 of the spout member 6 of the bag 2.

A rail moving mechanism 150 is provided to reciprocate the movable rail portion 55a in the front-rear direction. The rail movable mechanism 150 includes a blade support member 141.
Is provided with a support plate 151 attached to the main body. And
The support plate 151 has a driving means 1 such as an air cylinder.
52 and a guide plate 153 are attached. Also,
A movable plate 155 is connected to the pin ton 154 of the driving means 152, and a movable rod 156 supported by a guide plate 153 so as to be able to move forward and backward is also connected to the movable plate 155.
Further, the upper ends of a pair of front, rear, left and right connecting plates 157a, 157b are attached to the movable rod 156, respectively.
A pair of left and right movable rail portions 55a is attached to the lower end of b.

A rail support plate 159 is attached to the roller conveyor 62 via a connection plate 158 (see FIG. 7) so as to be located above the roller conveyor 62. The rail support plate 159 is connected to the connection plate 160 A pair of left and right downstream fixed rail portions 55c are attached via (see FIG. 7).

Next, the operation of the rail movable mechanism 150 and the bag separating mechanism 67 configured as described above will be described.

In the continuous bag filling type BIB manufacturing apparatus of the present embodiment, any one of bags of various sizes, large and small, is selectively used as the bag 2 constituting the continuous bag body 1 shown in FIG. Can be used. For this reason, the blade support member 141 for the roller conveyor 62 (in other words, the blade 1
44), the position in the front-rear direction can be adjusted. A bag 2 having a long distance from the center of the spout forming member 4 of the bag 2 shown in FIG. 2 to the side 21a on the downstream side of the sheet-shaped bag body 3 (that is, a large bag 2) and a short bag are used. 2 and the operation handle 146
By operating the positioning member 123,
(That is, the position of the solid line in FIG. 12) in the front-rear direction of the blade 144 is changed in advance. That is, when the operating member 146 is operated to rotate the rotating member 147 clockwise in FIG.
The rotation of 48 is transmitted to the rack 145, and the rack 145 moves downstream. For this reason, the blade support member 141 moves downstream with the blade 144 and the driving means 142, so that the large-sized bag 2 is used. Further, if the operation handle 146 is operated in the opposite direction to the above-described case, the operation opposite to the above-described case is performed.

As described above, the most downstream bag 2 of the bag continuum 1 moves on the roller conveyor 62 by its own weight, and its upstream end is the blade support member 14 of the bag separating mechanism 67.
When the movable rail portion 55a reaches the vicinity of the spout member 1 (that is, the vicinity of the bag separating position) and stops, the movable rail portion 55a keeps being engaged with the ring-shaped lower groove 12 of the spout member 6 of the spout forming member 4 while driving the drive means 152. As a result, it is driven substantially linearly from the state shown in FIG. 13 toward the downstream side, and further descends below the downstream fixed rail portion 55c as shown in FIG. For this purpose, as shown in FIG.
A relatively large gap 161 is created between the upstream end of 5a and the downstream end of the upstream fixed rail 55b.

Next, the blade 144 is driven substantially linearly downward from the state shown in FIG. 13 by the driving means 142 and passes through the gap 161 as shown in FIG. Cutting auxiliary line 8 (see FIG. 1)
The bag continuum 1 is pressed almost along. To this end, the most downstream bag 2 of the bag continuum 1 and the adjacent bag 2
Is pushed off along the cutting auxiliary line 8, so that the most downstream bag (that is, the bag with liquid) 2 is separated from the continuous bag 1.

Then, the separated liquid bag 2
Moves on the roller conveyor 62 by its own weight. When the liquid bag 2 is moved, first, only the pair of left and right movable rail portions 55a is attached to the spout member 6 of the bag 2.
A short time later, the pair of left and right downstream fixed rail portions 55c are also engaged with the spout member 6.
And a little later, the pair of left and right movable rails 55a terminates and no longer engages with the ring-shaped lower groove 12 of the spout member 6, and thereafter, A pair of left and right downstream fixed rail portions 55
Only c engages with the ring-shaped intermediate groove 22 of the spout member 6. Therefore, the spout forming member 4 of the bag 2 is moved by being guided by the pair of left and right guide rails 55 in any case. The liquid bag 2 is moved by the shutter plate 1 of the bag body stopping mechanism 171 of the bag stopping mechanism 68.
It continues until it comes into contact with 76 and stops.

On the other hand, when the liquid-containing bag 2 is cut off from the bag continuum 1 as described above, the next bag 2, which is the most downstream side of the bag continuum 1, is treated in the same manner as described above. The liquid is filled by the liquid injection nozzle 66 of the liquid filling mechanism 64. The blade 144 is driven substantially upward by the driving means 142 and returns to the home position.

Next, the movable rail portion 55a at the forward movement position shown in FIG. 14 is driven toward the upstream side by the driving means 152 and returns to the backward movement position shown in FIG. The return movement of the movable rail portion 55a may be performed immediately after the movable rail portion 55a is no longer engaged with the ring-shaped lower groove 12 of the spout member 6 of the liquid bag 2.

[0080]Bag stop mechanism (FIGS. 15-17)  The bag stop mechanism 68 is located on the upstream side as shown in FIG.
Bag body stop mechanism 171 and spout stop mechanism on the downstream side
172. And, the bag body stopping mechanism 17
1 includes a guide rail 55 and a roller conveyor 62.
Roller conveyor that is configured to be almost inverted U-shape
62, and a shutter support member 173 attached to
Air cylinder mounted on shutter support member 173
Drive means 174 and a fixed gear of the drive means 174
The driving means 174 is connected to the
The shutter plate (that is, the bag body stopping
(Stopper means for stopping) 176.

As shown in FIG. 15, the spout stop mechanism 172 is attached to the most downstream connecting plate 158 (see FIG. 7) attached to the roller conveyor 62 so as to be located above the guide rail 55. A support plate 181, a driving means 182 such as an air cylinder mounted on the upper holding plate 181, and a piston 1 of the air cylinder 182;
83 is connected to the substantially flat stopper plate (ie,
184). And
This stopper plate 184 is normally used in FIGS.
As shown in FIG.
5, but can be driven to the downstream side by the air cylinder 182 to move to the forward movement position shown in FIG.

Next, the operation of the bag body stopping mechanism 171 and the spout stopping mechanism 172 will be described.

As described above, when the liquid-containing bag 2 comes into contact with the shutter plate 176 of the bag body stopping mechanism 171 and stops almost completely, the shutter plate 17 at the return position shown in FIG.
6 is driven substantially upward by the driving means 174 and moves to the forward movement position shown in FIG. As a result, while the spout forming member 4 is guided by the pair of left and right guide rails 55, the liquid-containing bag 2 starts moving slowly further on the roller conveyor 62 further downstream. The downstream portion of the liquid bag 2 is a roller conveyor 62.
Begins to fall downward from the downstream end, and when most or almost all of the fall ends, the spout forming member 4 comes into contact with the stopper plate 184 and stops. For this reason, most or almost all of the liquid bag 2 is dropped from the roller conveyor 62 and the frame 75 of the shooter bucket 74 is dropped.
Since at least the lower part is inserted into the inside and only the spout forming member 4 is substantially supported, as shown in FIG. 17, it is substantially suspended. In addition,
In this suspended state, the upper end of the liquid bag 2 is
It may be slightly in contact with the downstream end of the roller conveyor 62, or may be slightly placed on the downstream end of the roller conveyor 62. Further, the time during which the liquid bag 2 is held in the suspended state is set so that the liquid bag 2 is securely stored in a desired state in the box 31 and the working time is not unnecessarily long. It is preferably from 0.2 to 5.0 seconds, more preferably from 0.5 to 3.0 seconds.

When the suspended state of the liquid bag 2 has passed for an appropriate period of time, the stopper plate 184 at the reversing position shown by the solid line in FIG. 16 is driven by the driving means 182 toward the downstream side, and Move to the indicated forward movement position. Accordingly, the spout forming member 4 of the liquid bag 2 which has been forcibly stopped by contacting the stopper plate 184 is moved to the stopper plate 1.
Since it is released from the forced stop by the pair of guide rails 84 and the left and right guide rails 55, the liquid-containing bag 2, which has been almost suspended in the air, drops substantially downward by its own weight and is placed in the box 31 at the raised position shown in FIG. Is stored in. In this case, the liquid-containing bag 2 immediately before the suspension state ends is almost always in a constant posture, so that when the liquid-containing bag 2 falls almost downward and is stored inside the box 31, the liquid-containing bag 2 is poured. The mouth forming member 4 can be reliably arranged at a position close to the substantially oval portion 40 (see FIG. 4) of the opening forming mechanism 33 of the box 31.

Next, the shutter plate 176 is
4, the stopper plate 184 is driven by the driving means 182 toward the upstream side to return to the return position. Further, the box 31 is lowered to the lower position shown in FIG. 15 by the forklift mechanism 73, and then sent to the next step by the roller conveyor 72 for transferring the box.

In the above embodiment, each bag 2 is filled with liquid such as drinking water.
Various articles such as granules, powders, slurries, creams, and gases can be filled or contained.

Further, in the above-described embodiment, the individual bags 2 are cut off from the continuous bag body 1 in which a plurality of bags 2 are continuously formed in a longitudinal shape. May be used. In this case, the individual bags 2 may be sequentially sent out to the bag sending mechanism 63 by an automatic sending mechanism or manually.

In the above-described embodiment, the liquid bag 2 moves from the vicinity of the predetermined liquid filling position of the liquid filling mechanism 64 to the vicinity of the predetermined bag dropping position of the spout stop mechanism 172 of the bag stopping mechanism 68.
