Description

  The present invention relates to a container boxing system and a boxing method for stacking and packing a large number of containers in a case in a multistage manner.

For example, in the container boxing apparatus shown in Patent Document 1, for example, a container transport aligning means for aligning a large number of containers that are transported by filling with liquid, sealing, and stopping a group of containers at a fixed position; A boxing means having one or a plurality of grip heads in which a container gripper is disposed, gripping the container with the gripper of the grip head, and then moving the container up and down while moving horizontally to box the container in the upper opening case; A plurality of cases which are constituted by a case conveying means for restricting and conveying one or a plurality of the open cases and a container guiding means which moves in synchronization with the case conveying means, and is filled with liquid and sealed and conveyed. One or a plurality of grip heads and containers that are arranged in a case-by-case container gripper. Operating the top head moving means, lowering the containers being aligned and transporting while following their transport speed, grabbing the container group and ascending, then constraining one or a plurality of containers and following the open case being transported The container is guided and lowered by the container guiding means that moves horizontally and moves in synchronization with the case conveyance, and is packed in a box.

  However, the container boxing device of Patent Document 1 described above has the following problems. That is, first, this container boxing device requires a container transport alignment device for aligning the number of containers for one case in a vertically and horizontally adjacent state. There is a problem that the cost increases. In particular, when the case is changed and the accommodation number is changed, it is necessary to change the vertical and horizontal alignment state of the containers, and it is not possible to quickly cope with the change of the accommodation number in various cases.

  Secondly, since the grip head that holds a number of containers for one case that are vertically and horizontally adjacent to each other enters the case from above, the difference in height occurs between the container holding position and the boxing position. The device itself is getting larger.

  Thirdly, the grip head needs to enter a case after holding a number of containers that can be packed at a time, so that the plane area of the entire grip head needs to be slightly narrower than the upper surface opening of the case. For this reason, each grip of the grip head has to be smaller than the plane of the container, and the container that can be held is limited to a shape having a narrow upper part.

  In order to solve the above-mentioned drawbacks, the applicant of the present application is attached to a movable body that is movably provided between a container take-out position side and a container boxing position in Japanese Patent Application No. 2003-342824, and depends on the case width. A plurality of container holding members that simultaneously hold a predetermined number of containers, a case conveying device that conveys a case that accommodates a large number of containers in an open state, and a case conveying device that can be rolled over while being conveyed The container is packed with a case support member that rolls over the case transported to the boxing position and a rollover member that rolls over the case support member, and a predetermined number of containers are sequentially stacked and packed in the rollover case. A system was proposed.

In addition, a number of containers according to the case width are simultaneously held by the respective container holding members in a series state where they are adjacent to each other, the container holding members are moved to the boxing position, and are loaded into the boxing position with the upper surface opened. The case holding member is supported by the case supporting member, and the case is rolled over so that the upper surface opening faces sideways. A container boxing method was proposed, which is characterized by entering from the side and stacking in order.

  However, the container boxing system and the boxing method described above are characterized by sequentially storing a plurality of containers in a horizontal state in a state where the case is laid down, and packing the containers in a multistage manner. To store the first container, first stack the second and third containers in the same way. However, when storing the second and subsequent containers, the case lays on its side. Therefore, there is a problem that the container at the stage clogged earlier is easily collapsed due to vibration during housing, and the boxing operation becomes impossible when the container collapses.

In this case, it is necessary to interrupt the accommodation operation to facilitate accommodation of the container in the case, and the accommodation operation efficiency has been remarkably deteriorated. For this reason, in a system for packing containers using a boxing robot, there is a problem that the operation interruption time becomes long and the boxing work efficiency is remarkably lowered.

JP-A-9-104410

The problem to be solved is that when the containers are stowed in a multi-tiered manner in the case, the containers in the previous stage collapse and the containers cannot be accommodated.
Further, when the accommodated container collapses and cannot be accommodated, the accommodation operation efficiency is deteriorated by interrupting the container accommodation operation and accommodating the container manually.

The invention of claim 1 has a width in the row direction in which a predetermined number of containers can be accommodated inside and a width in the column direction in which a large number of containers can be accommodated in a multistage shape, and is carried into the boxing position with the upper surface opened. It is attached to a tilting means for tilting the case at a desired angle with respect to the vertical direction, and a movable body movably provided between the supply position side of the container and the packing position, and can hold the predetermined number of containers. In a container boxing system that includes a plurality of container holding means and packs a number of containers in a tilted case in a multistage manner, the container holding means, which is one fewer than the predetermined number, is arranged in proximity to the predetermined container One container holding means can be held at the same time and can be moved in the direction of approaching and separating from the container holding means arranged in the proximity state, and can be held in the proximity state. Container storage One container holding means is placed close to the means, and a predetermined number of containers are simultaneously accommodated in the row direction in the case, and then one container holding means is attached to the container holding means arranged in the proximity state. It is characterized in that a number of containers which are spaced apart and one less than a predetermined number are stacked in the row direction between the previously accommodated containers.
Further, the invention of claim 9 has a width in the row direction in which a predetermined number of containers can be accommodated inside, and a width in the column direction in which a large number of containers can be accommodated in a multi-stage shape, with the upper surface being open at the packing position. In the case that is carried in and tilted at a desired angle with respect to the vertical direction, one container fewer than the predetermined number is disposed in the proximity of the container holding means, and one container smaller than the predetermined number is simultaneously disposed. In a method of storing and packing a container with each container holding means provided so as to be able to hold and move one container holding means in the direction of approaching and separating from the container holding means arranged in proximity. (1) One container holding means is brought close to the container holding means arranged in the proximity state, and a predetermined number of containers are simultaneously held and accommodated in the row direction in the case. (2) Arranged in the proximity state. One container in the container holding means (1) the number of containers less than the predetermined number is stacked between the predetermined number of containers previously accommodated by separating the holding means and simultaneously holding the number of containers less than the predetermined number; A large number of containers are accommodated in the case by repeating (1) and (2).

The present invention efficiently and surely performs the boxing operation by preventing the container of the previous stage from collapsing when the second and subsequent stages are stored when the containers are stacked in a standing state in the case. be able to.

The present invention avoids the collapse of the container of the stage previously accommodated during accommodation by tilting the case at a predetermined angle when the container is accommodated in a multistage form and packed in a case.

The present invention will be described below with reference to the drawings showing examples.
1 to 4, a container boxing system 1 includes a container transport device 3, a container take-out and supply device 9 that takes out a container 5 and supplies the container 5 into a case 7, a case transport device 33 that sequentially transports the case 7, and a case transport It comprises a case tilting mechanism 11 that tilts the case 7 transported to the boxing position of the device 33.

  The container conveying device 3 is a bottom between a pair of left and right guide bodies 13 that convey and guide the containers 5 made of synthetic resin such as PP, PE, PET, etc. to the container takeout position side in a state of being arranged in series adjacent to each other. It has a structure in which a conveying device 3a (FIG. 1 shows a belt conveying device) in which a large number of rollers and an endless belt extending in the conveying direction are mounted on the side.

  A counting member (not shown) for counting the number of transported containers 5 is provided on the container unloading position side of the container transporting device 3, and the number of containers 5 carried in based on a signal from the counting member is determined in advance. When the set number is reached, a separating member (not shown) enters the conveying path of the container conveying device 3 to separate the container 5 from the other. For example, as will be described later, the separation member is operated when the number of containers 5 carried into the container take-out position becomes six and when the number becomes five. In order to accommodate the containers 5 in the case 7 in multiple stages, for example, each stage is accommodated by alternately combining six rows and five rows.

  The container take-out and supply device 9 controls the movement of the container holding members 15 and 38, which will be described later, between the container take-out position of the container transfer device 3 and the boxing position for supplying the container 5 into the case 7 carried in. The container 5 is taken out and held at the same time, and then accommodated in the case 7 and packed in a box. The main body frame 17 has a length extending from the container extraction position and the boxing position to form a first part of the movable body.

  The first movable body 19 is provided with a frame 21 extending in a direction orthogonal to the moving direction of the first movable body 19, and the second movable body 23 constituting a part of the movable body is reciprocated on the frame 21. To be supported. An upper and lower frame 25 constituting a part of the movable body is supported on the second movable body 23 so as to be movable up and down, and a holder 27 extending in the moving direction of the first movable body 19 tilts below the upper and lower frame 25. It is attached via the attitude control device 29. The movement of the first and second movable bodies 19 and 23 and the upper and lower frames 25 is controlled by an electric motor (not shown) such as a servomotor capable of numerical control.

  The tilt posture control device 29 described above includes a reverse drive member 29c such as a servo motor that rotates a reverse rotation shaft 29b pivotally supported by a first mounting plate 29a fixed to the lower portion of the upper and lower frames 25 at an arbitrary angle. And a horizontal drive member 29e such as a servo motor, which is provided on a second mounting plate 29d attached to the reverse rotation shaft 29b and has a vertical axis and a holder 27 attached to the rotary shaft. Turn horizontally and reverse at an arbitrary angle.

  In the illustrated example of the system, the container holding members 15 and 38, which will be described later, are accommodated by the tilting posture control device 29 so as to be opposed to the placement surface of the container 5 in the tilted case 7, but the container 5 is taken out. Depending on the positional relationship between the position and the packing position, it is necessary to rotate the container holding members 15 and 38 in reverse and horizontally by the tilting posture control device 29.

  A plurality of (two in the example shown in the figure) mounting shafts 31 provided on the holder 27 are provided with mounting plates 31a at the distal ends thereof. The mounting plates 31a include five mounting plates 31a in the illustrated example. The container holding members 15 are respectively attached via elastic members 26 such as compression springs. The container holding member 15 is configured such that, for example, an adsorption member 15b is provided on the outer surface of a pair of opening / closing bodies 15a that are opened and closed by the operation of an air cylinder, and the closed opening / closing body 15a is inserted into the upper opening of the container 5 The opening / closing body 15a is opened and pressed, and the suction member 15b is suctioned to hold the container 5 with an internal grip.

    A rod 28 is supported at the end of the holder 27 so as to be slidable in the longitudinal direction, and a movable holder 32 is fixed to the tip of the rod 28. The movable holder 32 is configured to reciprocate by an operating member 34 such as a cylinder provided in the holder 27 so as to contact and separate from the holder 27. The movable holder 32 is provided with a mounting shaft 36 similar to the mounting shaft 31 described above in parallel with the mounting shaft 31 described above, and the mounting plate 36a provided at the tip of the mounting shaft 36 has the container described above. A container holding member 38 having a pair of opening / closing bodies 38a similar to the holding member 15 and having an adsorption member 38b provided on the outer surface of each opening / closing body 38a is attached via an elastic member 40 such as a compression spring.

  A case transporting device 33 such as a roller conveyor or a belt conveyor is disposed on the box take-out position side of the container take-out supply device 9, and a case tilting mechanism 11 is provided at a box filling position in the middle of the case transport device 33. The case support 35 of the case tilting mechanism 11 is provided so as to be tiltable in the conveyance orthogonal direction with respect to the main body frame 37. The case support 35 rises along each side surface of the case 7 on both sides of the rectangular frame-shaped bottom frame 35a in which the plane supporting the bottom surface of the case 7 to be conveyed substantially coincides with the plane of the case 7 at least in the conveyance orthogonal direction. A front surface (a surface viewed from the conveying direction) in which a pair of front and rear side frames 35b and 35c is formed in a horizontal U shape.

An operation member 39 such as a cylinder provided on the main body frame 37 is connected to the side frame 35c on the boxing position side of the case support 35, and the case support 35 crosses the case transfer device 33 by the operation of the operation member 39. The position is separated from the transport surface of the case transport device 33 and rotated between the tilt position at an arbitrary angle.
The tilt angle of the case support 35 is set to an arbitrary angle by bringing the stopper screw 20 screwed into the main body frame 37 so as to be able to advance and retract into contact with the case support 35. As the tilt angle, the center line of the case 7 is arbitrarily set within a range of 30 to 60 ° with respect to the vertical line.

  The bottom frame 35a is provided with a large number of rollers 41 having axes in the conveyance orthogonal direction, and is configured to be able to be carried out to the case conveyance device 33 side to which the case 7 placed is connected. Further, a pressing plate 43b that extends in the transport direction and presses the side surface of the case 7 is provided at a middle portion in the transport direction of the side frames 35b and 35c. Is pinched. Further, a regulating plate 45b that comes into contact with the side surface in the carrying-out direction of the case 7 is provided on the operating member 45a such as a cylinder on the carrying-out side of the side frames 35b and 35c, and the positioning is performed by bringing the case 7 into contact with the regulating plate 45b. is doing.

Next, the boxing action and method of the container 5 by the container boxing system 1 will be described.
The first and second movable bodies 19 and 23 and the upper and lower frames 25 are controlled to move, and the container holding members 15 and 38 are carried in a state of being aligned in a straight line by the container transport device 3 and separated from the other containers 5 by the separation member. The six containers 5 thus placed are positioned above. At this time, the container holding members 15 and 38 are aligned with the arrangement of the six containers 5 carried by the container transporting device 3 while the axis of the mounting shafts 31 and 36 are directed vertically by the tilting posture control device 29. The attitude is controlled so that Further, the open / close bodies 15a and 38a of the container holding members 15 and 38 are operated in directions close to each other.

  In the above state, the upper and lower frames 25 are controlled to move downward, and the opening / closing bodies 15a and 38a of the container holding members 15 and 38 corresponding to the containers 5 aligned in series are inserted into the respective containers 5 and then opened and closed. 15a and 38a are opened to press the inner surface of the container 5 and are sucked and held by the suction members 15b and 38b (see FIG. 5). After the above holding operation, the upper and lower frames 25 are controlled to be lifted and the containers 5 held by the container holding members 15 and 38 are taken out from the container transfer device 3 and then the first and second movable bodies 19 and 23 are necessary. Accordingly, the movement of the upper and lower frames 25 is controlled to move the container holding members 15 and 38 holding the container 5 to the boxing position.

In parallel with the movement operation of the container holding members 15 and 38 described above, or after the movement operation, the case 7 having the upper surface opened into the case support 35 of the case tilting mechanism 11 provided in the middle of the conveyance of the case conveyance device 33 is carried in. Then, the case 7 is positioned in contact with the lower side surface of the regulating plate 45b moved in the direction approaching each other by the operation of each actuating member 45a, and then approached by the operation of each pressing actuating member 43a. It is clamped by the pressing plate 43b that moves to (see FIG. 6). Next, the operating member 39 is operated in the above state, and the case support 35 is rotated at a predetermined angle to tilt the case 7. (See Figure 7)

Next, the container holding members 15 and 38 will be described later by driving the reverse drive member 29c of the tilt attitude control device 29 during or after the container holding members 15 and 38 holding the containers 5 are moved to the boxing position. Is tilted to coincide with the tilt angle of the case 7. Depending on the arrangement relationship between the container transport device 3 and the case transport device 33, the horizontal drive member 29e is driven to tilt the container holding members 15 and 38 so that the container 7 in the case 7 faces the mounting surface of the container 5 horizontally. Move.

The first and second movable bodies 19 and 23 and the upper and lower frames 25 are controlled to move, and the side surfaces located on the lower side of the case 7 tilted, for example, six containers 5 held by the container holding members 15 and 38 are arranged. After being positioned at the lowest level as a reference (see FIG. 8), the container holding members 15 and 38 are caused to enter the case 7 in the above state. Next, as shown in FIG. 9, the opening / closing bodies 15 a and 38 a are rotated in the closing direction and the suction by the suction members 15 b and 38 b is released to release the holding of the container 5. 38 is moved in a direction away from the case 7 and the open / close bodies 15a and 38a are extracted from the containers 5 to accommodate the containers 5 and then returned to the container take-out position of the container transfer device 3.

Now, when the container 5 accommodated in the case 7 is cylindrical, in order to efficiently accommodate a large number of containers 5 in the case 7 while preventing positional deviation from each other, they are accommodated in the case 7. In contrast to the six containers 5 in the first row, the five containers 5 in the second row are accommodated while being positioned between them.

Therefore, when the container 5 to be packed next is taken out, the first and second movable bodies 19 and 23 and the upper and lower frames 25 are controlled to move the five container holding members 15 above the five containers 5. Move to. At this time, the container holding member 38 is located above a place where the container 5 is not present. In this state, the upper and lower frames 25 are controlled to be lowered in the same manner as described above, and each pair of the opening / closing bodies 15a is moved into the respective containers 5 and then held inside by being pressed and adsorbed.

In the same manner as described above, the first and second movable bodies 19 and 23 and the upper and lower frames 25 are controlled to move, and the respective container holding members 15 holding the five containers 5 are tilted and accommodated at the tip of the case 7. Five containers 5 are accommodated between the containers 5 in the first row.

As shown in FIG. 10, when the five containers 5 in the next row are accommodated between the six containers 5 previously accommodated, the next row is located between the six containers 5 previously accommodated. In order to position each container 5, it is necessary to move each container holding member 15 holding the container 5 in the width direction of the case 7 by a width corresponding to about half of the container 5, thereby holding the container 5. The missing container holding member 38 interferes with the case 7 and hinders the boxing operation.

In order to avoid this, as shown in FIG. 11, prior to the container holding member 15 entering the case 7, the operation member 34 is operated to move the movable holder 32 away from the holder 27 to move the container holding member 15. 38 is positioned outside the case 7 to avoid interference with the case 7 so that only five container holding members 15 can enter the case 7.

As described above, when the containers 5 are sequentially accommodated in the case 7 while switching the number of containers 5 held only by the container holding members 15 and 38 and the container holding member 15 and the first-stage boxing operation is completed, the same as described above. Then, the boxing operation of the container 5 in the second stage is performed. When the next-stage container 5 is accommodated, there is a risk that the container 5 previously packed in the box may collapse due to vibration during accommodation. However, as shown in FIG. Since it is tilted at an angle, it is possible to reliably prevent the container 5 at the previous stage from collapsing and to perform the accommodating operation with certainty.
When the container 5 is accommodated in a multi-stage shape with respect to the inside of the case 7 and the boxing operation is completed, the actuating member 39 is moved backward to return the case support 35 to the original position side and raise the case 7. Then, the pressing actuating member 43a is moved backward to move the pressing plate 43b, and the actuating member 45a is moved backward to move the regulating plate 45b away from each other to release the pressing of the case 7. In this state, as the next case 7 is carried in, the case 7 in which the container 5 is packed is pushed out to the carry-out side and carried out.

In the present embodiment, when a large number of containers 5 are stacked and accommodated in the case 7, the container 5 is accommodated while the case 7 is tilted, so that the previously accommodated container 5 collapses. It is possible to prevent the container 5 from becoming unacceptable, and to perform the boxing operation of the container 5 smoothly and efficiently.

  This embodiment is a system in which a synthetic resin container molded by a resin molding machine is taken out and boxed directly in a case. In FIG. 13, a resin molding machine 121 for molding a synthetic resin container 5 (FIG. 13). (Only the fixed side platen of the resin molding machine) is equipped with a molded product take-out machine 123 for taking out the container 5 as a molded product. The resin molding machine 121 is a conventionally known injection molding machine or hollow molding machine, and is mounted with a mold capable of simultaneously molding a plurality of, for example, three containers 5.

The molded product take-out machine 123 is conventionally known and has a structure similar to that of the container take-out and supply device 9 in the first embodiment, and a chuck 125 that holds the three containers 5 as molded products at the same time. The container 5 is controlled to move in the axial direction, the longitudinal axis orthogonal direction, and the three-dimensional direction in the vertical direction, and the molded and hardened container 5 is taken out. When taking out containers 5 which are a plurality of molded products from the mold, it is necessary to take out each container 5 at an appropriate interval, but it is necessary to adjoin each container 5 when boxing in case 7. There is.

Therefore, as the chuck 125, as shown in FIG. 14, one container holding member 125b is fixedly provided to the chuck plate 125a, and movable bodies 125d to which the container holding members 125c are respectively attached are arranged close to the chuck plate 125a. It is provided so as to move in the direction and the direction of separation. The movable body 125d is moved in the approaching direction and the separating direction by the cylinders 127 provided on the chuck plate 125a.

As a result, the containers 5 can be taken out apart from each other when taken out from the mold, while the containers 5 can be placed close to each other when packed. In addition, about each member of the molded product extraction machine 123, the code | symbol similar to the code | symbol attached | subjected to the container extraction supply apparatus 9 of Example 1 is attached | subjected, and description is abbreviate | omitted. Further, the chuck 125 may have a structure for holding the container 5 by opening and closing a plurality of pairs of opening / closing bodies and sucking the suction member as in the case of the container holding members 15 and 38 of the first embodiment.

In addition, the chuck 125 is attached to the lower part of the upper and lower frames 25 via the tilt posture control device 29 of the first embodiment, and is configured to rotate and rotate horizontally at an arbitrary angle. Thus, the chuck 125 is moved relative to the placement surface of the container 5 in the tilted case 7.

The system of the second embodiment is similar to the configuration in which the container transport device 3 is excluded from the container boxing system 1 of the first embodiment and the molded product take-out machine 123 is used in place of the container take-out and supply device 9. Are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.

As the molded product take-out machine 123 shown in the figure, a three-dimensional moving type take-out machine is shown. However, the molded product take-out machine 123 may be either a horizontal running type in which the chuck 125 is moved in the horizontal direction or a swiveling type in which the chuck 125 is rotated. it can.

Next, the boxing action and method of the container 5 molded by the resin molding machine 121 and taken out by the molded product take-out machine 123 will be described.
When the mold opening completion signal when the three containers 5 are formed by the resin molding machine 121 and cooled to a temperature that can be taken out and cured is input to the molded product takeout machine 123, the molded product takeout machine 123 is moved to the chuck 125. Is moved between molds that have been opened by mold control, and the molded container 5 is simultaneously held and removed from the mold, and then the movement control is performed so that the chuck 125 holding the container 5 is positioned at the boxing position.

In parallel with this take-out operation or when the chuck 125 is moved to the boxing position, it is carried into the case support 35 of the case tilting mechanism 11 provided in the middle of the carrying of the case carrying device 33 in an open state. After the case 7 is positioned by the restricting plate 45b and held by the pressing plate 43b, the operating member 39 is operated to rotate the case support 35 by a desired angle to tilt the case 7.

Further, when the chuck 125 is moved to the packing position or after the movement, each cylinder 127 is operated to move the containers 5 held by the container holding members 15 and 38 so as to be adjacent to each other. (See Figure 15)

Further, in parallel with the take-out operation or when the chuck 125 is moved to the packing position, the chuck 125 holding the container 5 by controlling the tilting posture control device 29 is relative to the placement surface of the container 5 in the case 7. Tilt to make the posture control.

Next, the movement of the chuck 125 holding each container 5 is controlled so that each container 5 held so as to be continuous in the horizontal state is positioned at the lowermost stage on the side surface of the case 7, and then the movement of the chuck 125 is further controlled. After the container 5 has entered the case 7, the holding of each container 5 by the chuck 125 is released and accommodated.

When accommodating the five containers 5 in the second row after accommodating the first row of containers 5 in the case 7 by repeating the above operation, first, in the same manner as described above, the container holding members 125b and 125c of the chuck 125 are accommodated. After holding the three containers 5 held between the containers 5 accommodated in the first row, the two containers 5 are held by the container holding member 125b and one container holding member 125c. Contain.

At this time, as shown in FIG. 16, when the chuck 125 is advanced into the case 7, one of the cylinders 127 is operated, and the container holding member 125c holding the container on the corresponding side is moved to the container holding member 125b located at the center. A container that does not hold the container 5 by keeping the other cylinder 127 in the non-operating state and keeping the container holding member 125c that does not hold the container 5 away from the container holding member 125b located in the center. The holding member 125 c is positioned outside the case 7 so that the chuck 125 can enter the case 7.
A large number of containers are accommodated in a multistage manner in the case 7 tilted by repeating the above operation, and the boxing operation is performed.

Also in this embodiment, when the next container 5 is accommodated, there is a possibility that the container 5 in the previously accommodated row may collapse. However, since the case 7 is tilted as described above, the container 5 is accommodated first. It is possible to prevent the collapsed container 5 from collapsing.

In the first and second embodiments, the container 5 is boxed and the case 7 is folded back so that the lid piece hangs along the side plate when the container 5 is boxed. Supplied. However, when the case 7 rolls over, the cover piece may return and block the upper surface opening, thereby hindering accommodation of the container 5.

In order to prevent this, as shown in FIG. 17, the upper part of the pressing plate 43b and the restriction plate 45b is formed to extend upward, and in the restriction plate 45b, the case 7 to be carried in the restriction plate 45b. Even when the lid piece 7b is pressed at the time of contact and positioning and the case 7 is clamped, the lid piece 7a is pressed at the same time to prevent the lid pieces 7a and 7b from returning and blocking the opening. Good.

In the above description, the open / close bodies 15a and 38a of the container holding members 15 and 38 are opened and closed to hold and hold the containers 5, but the containers by the container holding members 15 and 38 are used. The holding mode 5 is not limited to this. Of course, if the upper part is a narrow or small-diameter container, the container 5 may be held by an outer grip.

In the above description, the cylindrical containers 5 are stacked in a multi-stage manner and packed in a box, and for example, the five containers 5 are positioned with respect to each other, for example, between the six containers 5 that have been packed in the box. In the case where the container 5 has a rectangular tube shape, the next container 5 is stacked on the container 5 previously packed so as to coincide with each other. Can be boxed.
Even in this case, by tilting the case 7 when the container 5 is accommodated, the container 5 previously accommodated can be prevented from collapsing and becoming unable to be accommodated.
