Description

[Detailed description of the invention] [Industrial use distribution]

The present invention relates to a packaging system for a plurality of packaging containers having a specific shape, and more specifically, the present invention relates to a packaging system for a plurality of packaging containers having a specific shape. The present invention relates to a packing system for packing a plurality of bottles containing 11 to 21 bottles made of synthetic resin such as terephthalate.

[Technical background]

Conventionally, for example, soy sauce, Japanese sake, soft drinks, etc. are generally filled into glass bottles after production, stored in wooden boxes in fixed numbers, and delivered from the manufacturing factory to users such as retail stores. However, glass bottles are vulnerable to external shocks, and when shipped, the bottles are simply stored in a wooden box, and there is no means to prevent the bottles from moving inside the box. It is easily damaged by moving within the wooden box due to vibration during shipping, coming into contact with the inside of the wooden box or other bottles, or falling. In addition, large glass bottles filled with contents are heavy, and especially in recent years, many types of carbonated drinks are
Since it is common for these carbonated drinks to be sold in packs of 11 to 21, they are relatively large, and the walls of the entire bottle are made thicker to strengthen the internal pressure. Alternatively, by providing a cylindrical skirt or the like to cover and protect the bottom of the bottle, where the internal pressure is greatest, the volume becomes larger, resulting in increased transportation costs. In addition, it is essential to collect the bottles, trays (resin flutes) and wooden boxes that have been used as chambers, and to recycle the collected bottles, which requires labor and equipment costs. In some cases, bottles, wooden boxes, etc. were lost or damaged and could not be recovered.

[Prior art and its problems]

As a means of solving the above-mentioned drawbacks, as shown in Figure 10, bottles containing II to 21 for filling carbonated drinks are made of PE.
T, is made of synthetic resin such as polyester, and if necessary, the lower part of the body 13 of the bottle 10 is provided with a bottom and a cylindrical skirt 15.
They are packaged and protected, and after being filled with contents, they are delivered from the factory to the user by storing them in delivery trays containing 4 or 6 bottles. Bottles made of synthetic resins such as PET are more resistant to external impacts than glass bottles, are less likely to be damaged by contact between bottles, and are lightweight, so they can be used to strengthen internal pressure for carbonated drinks. Even if the overall wall thickness is made slightly thicker, it is still lighter than a glass bottle, and since it does not require collection or recycling after use, it is possible to reduce transportation costs and reduce the labor required for collection and recycling. Equipment for this is no longer required. However, since the bottles are stored separately in trays during shipping, they are easily affected by vibrations, and when the content is carbonated drinks, the vibrations can increase the pressure inside the bottle and cause the bottle to burst. In addition, trays for bottle delivery still need to be collected for reuse, and many trays become unrecoverable due to damage or loss, and the production costs of replenishing them are high. There is a drawback that it requires In order to solve these problems, it is desirable to tightly wrap multiple bottles after filling with contents so that they can be delivered as they are. Even if it were to be packed, it could only be tied horizontally to the body of the bottle, and the neck of the bottle could not be tied to the band, so it could not be said to be in a sufficient packaging state. That is, as shown in FIG. 10, for example, a bottle 10 containing 11 to 2j for filling with carbonated drinks etc. generally has a cylindrical body 13 and a neck 11 having a smaller diameter formed above the body 13. Therefore, the necks 1 of each of the plurality of bottles 100 on the conveyor line 20
1. If you want to hang a band on the outside, arch horizontal packing machine 3
Since there is a distance between the necks 11 of the plurality of bottles 100 on the zero side and the front surface of the main body 31 of the arch horizontal packing machine 30, that is, the welding mechanism, the plurality of bottles 100 are separated in the horizontal arch 33.
This is because it is impossible to tighten the band sufficiently around the neck 11 of 00. - 10,000, the body 13 of the plurality of bottles 10G is connected to the main body 3 on the side
The band can be tightened if it is packed tightly against the front side, so it is possible to wrap the band around the outer circumference of multiple bottles, such as 4 or 6 bottles, and tighten the entire bottle into a roughly rectangular shape.
If such a horizontal band is applied only to the bottle body, the bottle body is not equipped with any means to reliably prevent the band from falling and the bottles from shifting, which may cause problems during delivery by vehicle. If the band loosens due to vibration, the band may fall off along the body (or skirt) of the bottle, or the bottles may become misaligned when packed in the abbreviated form, resulting in a diamond-shaped overall shape. This may cause the band to become loose, causing the bottle to move, increase internal pressure, and cause damage.
This will make subsequent manual transportation impossible or difficult. These problems are not limited to the above-mentioned bottles containing carbonated drinks, but are common to packaging containers having a similar shape to the above-mentioned bottles, that is, packaging containers in which the neck is formed to have a smaller diameter than the body. .

【the purpose】

The present invention solves the conventional problems associated with the packaging and delivery of bottles and other packaging containers, as described above, and makes it possible for the first time to form a packing operation line for multiple packaging containers. Where the content is filled, it must be delivered from the manufacturing factory to the user.
h g −pg −L j= 1m J
A plurality of packaging containers of 1h are packed tightly together on the conveyor line with the ribs formed in a convex shape on the curved surface of the skirt interlocking with each other, and are packed firmly and portablely on the conveyor line. In addition, the ribs prevent the band passed between multiple packaging containers from falling and the packaging containers from shifting during delivery, thereby reducing the effects of vibrations on each packaging container during delivery. This prevents the packaging container from bursting due to an increase in internal pressure, and makes it possible to carry multiple packaging containers by hand in a W1Y!! manner. An object of the present invention is to provide a packaging system that does not require boxes or trays.

[#l formation]

To achieve the above object, the present invention comprises a packaging container, a conveyor line for transporting the packaging container, and a packaging machine disposed between the conveyor lines; There is a shadow line above the torso, and the neck has a smaller diameter than the torso, which has formed a shadow line.
It comprises a flange disposed around the neck in the horizontal direction, and a rib consisting of an MR-like convex part formed on a skirt surface having an inner diameter into which the body circumferential surface and/or the bottom part can be fitted. , the conveyor line consists of a belt and/or roller conveyor that conveys a plurality of the packaging containers in an upright state while abutting each other via the ribs, the packaging machine is disposed at the rear of the conveyor line in the traveling direction, an arch horizontal packing machine that performs banding between the flanges and shoulders of the plurality of packaging containers and/or the body horizontally; It consists of a horizontal packing machine that hooks one or more bands in a direction orthogonal to the band wound in the horizontal direction between the necks of packaging containers, and the arch horizontal packing machine and/or the arch horizontal packing *i structure. It is characterized by consisting of.

[Effect]

Therefore, according to the present invention, a plurality of packaging containers having a specific shape to be transported on the conveyor line are transported between the flange and the shoulder in a state in which the convex ribs formed on the circumferential surface of the skirt mesh with each other. and/or after packaging with a band hung horizontally on the body, or in a direction orthogonal to the horizontal band between the necks of a plurality of packaging containers hung horizontally with the band. It is wrapped with a band.

【Example】

Hereinafter, details of the present invention will be explained based on drawings showing embodiments. Note that the same reference numerals are used for the same members as those used in the description of the prior art. FIG. 1 shows a first embodiment of the present invention. In the figure, the present invention includes a bottle 10 as a packaging container of a specific shape as an object to be packed, and two conveyors that sequentially transport the bottle 10. 21 and 22, and two moss packing machines placed in the middle of the conveyor line 2G, namely, an arch horizontal packing machine 30 and a horizontal packing machine 40. The bottle 10 is for filling carbonated drinks, for example, and is made of PET or other synthetic resin, has a capacity of il to 2j, and has a generally spherical shape that protrudes outward as shown in FIG. It has a cylindrical body 13 above the bottom 14 formed by the above, and upwards from the shoulder 12 at the upper end of the body 13.
A neck portion 11 having a smaller diameter than the body portion 13 is formed to protrude. The area from the shoulder 12 to the neck 11 has a streamlined shape, and the neck 1
A cap 18 is screwed into the opening at the upper end of 1. At the neck 11 of the bottle 10, a hole 17 located directly below the cap is formed to have a somewhat larger diameter than the cap 18. The bottle 10 includes a skirt 15 that covers the lower peripheral surface of the body 13 and the bottom 14 . In other words, this skirt 1
5 has a cylindrical shape with a bottom and has an inner diameter into which the bottle body 13 can be fitted, and is fixed to the body 13 with adhesive, for example. As is clear from FIG. 5, the skirt 15 has convex grooves 6 extending vertically over the entire circumferential surface and projecting from the skirt 15 at regular intervals. In this embodiment, the rib 16 has a serrated cross-sectional shape as shown in FIG. The ribs do not need to be provided over the entire circumference of the skirt as described above, but may be formed to protrude continuously in the vertical direction, for example, at positions that divide the circumference of the skirt into four equal parts. The ribs may be formed in caramel-like protrusions of an appropriate size at appropriate intervals vertically and horizontally on the circumferential surface, and may be caramel-shaped on the foreboard of one of the skirts that touch each other.The cross-sectional shape of the entire rib may also be rack-shaped, gear-shaped, or other various shapes. 4 and 7, the skirt 15 can be formed into a shape that allows the ribs to engage with each other when bottles having skirts provided with similar ribs are brought into close contact with each other. A concave portion 19, such as an arc-shaped concave portion, is formed in the center of the bottom surface of the bottle 10, and is recessed in the direction of the bottom portion 14 of the bottle 10. Flange 1 with a larger diameter and provided on the neck 11
7, and the depth is at the upper end of the neck 11 (cap 18).
(upper end) to the upper surface of the flange 17. In FIG. 1, the conveyor line 20 consists of a conveyor 21 and a conveyor 22, and the bottles 10 are conveyed through guides (not shown) provided in the width direction of each conveyor, three in the traveling direction of the line and two in the width direction. Transfer in units of six in total in the direction of the arrow in the figure. The starting end of the conveyor 21 faces the work area for previous processes, such as filling the bottles 10 with contents and attaching caps,
The terminal end is located in front of a horizontal packaging machine 40, which will be described later. This conveyor 21 is, for example, a roller conveyor consisting of a large number of rollers arranged in parallel and connected to an ME motor via a sprocket, a chain, etc. bottle 10
0 does not reach the front of the arch horizontal packing machine 30, which will be described later, and when the predetermined packing process by the arch horizontal packing machine 30 is completed and the main body 31 and the horizontal arch 33 rise and return to their previous positions. This drive control is performed by a timer, a detection mechanism such as a phototube, a limit switch provided on the arch horizontal packing machine 30, and the like. The conveyor 22 has a starting end that is close to the terminal end of the conveyor 21 facing the horizontal packing machine 40, and a terminal end that extends to the next process, such as a loading area for packed bottles. The conveyor 22 is a belt conveyor that includes an endless belt and connects the endless belt to a drive motor via a sprocket, a chain, etc.
Moreover, this conveyor 22 runs on the conveyor line 20 6 times.
A plurality of bottles 100 to be transferred in units of bottles are transferred to a horizontal packing machine 4.
It is controlled to stop when it reaches the packing position in the vertical arch 42 of 0, and to operate when a predetermined packing process by the horizontal packing machine 40 is completed, and this drive control is performed by the conveyor 2.
Similar to 1, this is performed using a timer or a phototube and a limit switch. The number and types of conveyors constituting the conveyor line 20 are not limited to those described above. For example, the conveyor line 20 may be constituted by three or more conveyors, and the conveyor 21 may be a belt conveyor, the conveyor 22
may be constructed by a roller conveyor, or both may be constructed by a belt conveyor or a roller conveyor. In addition to controlling the drive of the conveyor using a timer or a phototube and a limit switch as described above, it is possible to use other means as appropriate, and the control method also depends on the number of conveyors and the number of bottles to be packed. It can be changed as appropriate depending on the number, arrangement, type of packing machine, etc. In the middle of the conveyor line 20, two packing machines, namely, an arch horizontal packing machine 30 and a horizontal packing machine 40, are arranged at regular intervals. The arch horizontal packing machine 30 is located at the rear, that is, at the front side in the direction of movement of the conveyor line 20,
This arch horizontal packing machine 30 includes a guide ball 32 that stands vertically, a main body 31 that is supported by the guide pole 32 so as to be able to rise and fall, and a band that is attached horizontally to the main body 31. The main body 31 is equipped with a U-shaped horizontal arch 33 that communicates with the way, and the main body 31 incorporates various mechanisms for supplying, pulling back, tightening, welding, and cutting the band, and is connected to a drive winding mechanism via a wire rope, chain, sprocket, etc. connected to. Then, this drive winding mechanism is activated by a timer or a photoelectric tube that controls the drive of the conveyor 21, and when the conveyor 21 is stopped, the main body 31 and the horizontal arch 33 are lowered along the guide ball 32, and the main body 31 and the horizontal arch 33 are lowered into the horizontal arch 33. Six bottles 100 are packed by horizontally wrapping bands around the necks 11, ie, between the flanges 17 and the shoulders 12, and around the bodies 13. On the other hand, a horizontal packing machine 40 is arranged in front of the arch horizontal packing machine 30 in the direction of movement of the conveyor line 20. This horizontal packing machine 40 includes band feeding and pulling back,
It is equipped with a main body 41 that incorporates various tightening, welding, and cutting mechanisms, and a horizontal U-shaped vertical arch 42 that is attached to one side of this main body 41 and communicates with a bandway within the main body 41, and the arch horizontal packaging. When the machine 30 reaches the six photo vertical arches 42 horizontally banded between the necks 11 and bodies 13, and the conveyor 22 is stopped by a timer or phototube, the necks of each of these bottles 100 11 and the rib 16 of the skirt 15, a band is applied in a direction perpendicular to the horizontally wound band. The number of packaging machines arranged along the conveyor line 20 can be changed as appropriate depending on the number of times of packaging, etc., but an arch horizontal packaging machine that performs horizontal banding at the rear, that is, the front side of the conveyor line 20 in the direction of movement. A horizontal packing machine is arranged ahead of the arch horizontal packing machine in the traveling direction of the conveyor line 20, and is arranged to hang a band in a direction perpendicular to the horizontally wound band. Next, the operation of the above embodiment will be explained. The bottles 10, which have now been filled with contents and capped, are placed upright on the conveyor 21 in every six bottles, three rows in the traveling direction of the conveyor line 20 and two rows in the width direction of the conveyor line 20. be done. When these six bottles 100 are transferred on the conveyor 21 and reach the front of the arch horizontal packing machine 30, that is, directly below the horizontal arch 33, the drive motor of the conveyor 21 is turned off by a phototube or a timer that detects this arrival.
Then, the conveyor 21 stops. At the same time, the main body 31 of the arch horizontal packing machine 30 descends along the guide balls 32, and when the horizontal arch 33 attached to the main body 31 is located at a height directly above the skirt 15, the main body 31 stops and the 6
A band is hung horizontally around the body 13 of the book bottle 100 and the book bottle 100 is packed. By this banding, each bottle is packed with the ribs 16 of the skirt 15 interlocking with each other and in close contact with each other. That is, in the bodies 13 of the plurality of bottles 100,
Skirt 1 by horizontal banding and tightening
The ribs 16 of 5 naturally interlock with each other to hold the plurality of bottles 1.
00 is tightly packed in a generally rectangular shape as a whole. Next, the main body 31 is raised, and the horizontal arches 33 are attached to the outside of the neck 11 of each of the plurality of bottles 100, that is, the seven flange 17.
When the main body 31 is located at a height between the shoulder 12 and the shoulder 12, the main body 31 stops and a band is hung horizontally between the flange 17 of each photo/L; At this time, the band that pops out from the horizontal arch 33 of the arch horizontal packing machine 30 descends somewhat due to gravity and wraps around the plurality of bottles 100, but the shoulders 12 of the bottles 10 are all streamlined. Because the band is formed at shoulder 1
2, the neck 11, that is, the shoulder 1
2 and the flange 17. In addition, since there is a distance between the front side of the main body 31 of the one-chip horizontal packing machine 30 and the main body side of the necks of the bottles that are in contact with this, it is important to tighten the bands sufficiently when hooking the necks 11 of the plurality of bottles 100. Therefore, the band is somewhat sagging when multiple bottles 1
It is wound around the neck 11 of 00. When the wrapping of the straps to the outside of the neck portions 11 of the plurality of bottles 100 is completed, the main body 31 of the arch horizontal packing machine 30, that is, the horizontal arch 33 rises and returns to its original position. Then, the motor of the conveyor 21 restarts driving due to the operation of a limit switch or a timer that detects this return, and the plurality of bottles 100 are transferred on the conveyor 21. Next, when the plurality of bottles 100 reach the horizontal arch 42 of the horizontal packing machine 40, the conveyor 22 is stopped by a phototube or a timer that detects this arrival, and first, the plurality of bottles lined up in three rows in the traveling direction of the line are stopped. 100 bottles of
A band is applied between the bottle necks of the first row and the bottle necks of the second row in a direction perpendicular to the horizontal band, that is, in the width direction of the conveyor line 20. After the slight movement and stop, the banding between the first and second rows is performed in the same way between the bottles in the second row and the bottles in the third row, so that the bands are hung in the width direction of the conveyor line 20 and packed. will be held. At this time, the band wound by the horizontal packing@40 firmly tightens the band hung around the necks 11 of the plurality of bottles 100 in the somewhat loose state. In addition, horizontal packing machine 4
Since the band wound by the band 0 is locked to the lower surface of the rib 16 which is in a meshing state at the contact part of the skirt 15, even if the tightening strength of the horizontal packing machine 40 increases, the band 1
No upward force is exerted on the band horizontally hung on the body 13 of the 00. . Therefore, the band of the body 13 does not shift upward. When the strapping by the horizontal packing machine 40 is completed, a limit switch that detects the completion of packing is activated, the motor of the conveyor 22 is driven, and the multiple bottles 1 that have been packed are
The 0G is transferred on the conveyor 22 and supplied to the next process. 8 and 9 show a second embodiment of the present invention in which the main body 31 of the arch horizontal packing machine 30 does not move up and down, and differences from the first embodiment described above will be explained. Note that the same reference numerals are used for the same members as in the first embodiment. The conveyor 21 consists of a roller conveyor equipped with a drive mechanism or a free roller conveyor inclined in front of the main body 31 of the arch horizontal packing machine 30, and is arranged with a slight interval from the front of the main body 31 of the arch horizontal packing machine 30, At the terminal end of the conveyor 21 located below the horizontal arch 33 of the arch horizontal packing machine 30, an insertion cylinder 51 whose rod expands and contracts in the horizontal direction is provided. This insertion cylinder 51 is equipped with an L-shaped suppression plate 59 that presses 2 rows x 3 bottles at the tip of a rod that moves forward and backward on the conveyor 21, and presses these 6 bottles 100 in the width direction. These bottles 10 are placed in front of the main body 31 of the arch horizontal packing machine 30.
0 and prevents the next bottle sent on the free roller conveyor from advancing by a horizontal rod 60 bent into an L shape and protruding in the width direction of the conveyor. on the other hand,
The receivers, which are located at the front of the arch horizontal packing machine 30 and receive the six bottles 100 pushed by the insertion cylinder 51 on the same plane as the conveyor 21, are two air cylinders equipped with a plate 58 at the tip of the rod. That is, the first lifting cylinder 62 and the second lifting cylinder 53 are arranged in an overlapping manner. Also, moving forward and backward in a direction perpendicular to the insertion cylinder 51,
The receiver transfers the six bottles 100 on the plate 58 to the conveyor 22.
A transfer cylinder 54 is provided at the front of the arch horizontal packing machine 30 and is equipped with a rod that moves forward and backward by a distance that allows transfer. Furthermore, at the approximate center of the front surface of the main body 31 of the arch horizontal packing machine 30, there are receivers for the first and second lifting cylinders 52, 63 directly below the plane formed by the band passing path in the horizontal arch 33, at a position that does not prevent the band from escaping. is the same as plate 5, or the receiver is 6 bottles 1 pushed up by plate 58
A substantially U-shaped guide frame 55 forming an opening slightly wider than 00 is attached. The conveyor 22 is adjacent to the conveyor 21 and separated by a gap that allows the band to pass through the vertical arch 42 of the horizontal packaging machine 40, so that the conveyors 22 arranged on the left and right sides of the vertical arch 42 operate synchronously. Drive mechanism 5
6. In the figure, 57 is a phototube that emits light onto the conveyor 22 via the vertical arch 42 at the front of the horizontal packaging machine 40. Here, to explain the difference between the operation of the second embodiment and the first embodiment, when the bottles are regulated by a guide in the upper width direction of the conveyor 21 and transferred while being arranged in two rows, the bottles are transferred to the transfer cylinder, which will be described later. The insertion cylinder 51 is actuated by the return signal 54, and the six bottles 100 are pressed against the front surface of the main body 31 of the arch horizontal packing machine 30 by the pressing plate 59 of the insertion cylinder 51. At this time, the first and second
The plate 58 on the lifting cylinder 52, 53 is the conveyor 21
The six bottles 100 are placed on the plate 58 of the receiver. On the other hand, a horizontal rod 60 connected to the suppression plate 59 prevents other bottles from advancing. Next, in response to a signal from a limit switch or the like that detects that the rod of the pushing cylinder 51 has reached its longest position, both of the two lifting cylinders 52 and 53 arranged in a superimposed manner extend, and the six bottles 100 to the position shown in FIG. At this time, the six bottles 100 rise while being regulated by the guide frame 55. Then, by a signal such as a limit switch that detects that the rod of the lifting cylinder 52, 53 has reached its longest position, the band of the first grain is connected to a plurality of bottles 100.
It is hung near the skirt of the person. The detection means in the main body 31 of the arch horizontal packaging machine 30 detects the end of this first strapping and issues a signal, which activates one of the lifting cylinders 52, 63, for example, a solenoid valve (not shown) of the first lifting cylinder 52. Activated, the plate 58 is lowered by the rod extension/retraction stroke of the first elevating cylinder 52. By this descent, the plurality of bottles 100 are wrapped around the necks 11 with bands. Note that the guide frame 55 is a horizontal arch 33.
It has the effect of regulating the escape posture of the band that escapes from the band. As described above, upon completion of this packing, a signal is sent to the solenoid valve of the second lifting cylinder 53, and the rod of the second lifting cylinder 53 descends to return to its old position. The receiver is board 58
When the transfer cylinder 54 returns to its old position, a signal detecting this return causes the transfer cylinder 54 to operate. Therefore, six horizontally banded bottles are transferred to the conveyor 22. Next, the rods of the transfer cylinder 54 and the insertion cylinder 51 are returned to their original positions. The six bottles transferred onto the conveyor 22 are driven by the drive mechanism 56.
When the bottle located at the rightmost end in the figure has slightly passed the vertical arch 42, it is detected by the phototube 57, and this detection signal causes the conveyor 22 to stop, and from now on, the first Similar to the embodiment, the straps are packed vertically between adjacent bottles. Upon completion of this packing, the conveyor 22 moves again and stops again when the leftmost bottle has slightly reached inside the vertical arch 42, and the second strap is applied vertically between adjacent bottles as in the first embodiment. Packing is done. When this second packing is completed, the conveyor 22 starts moving and the six packed bottles are sent to the next process. During this time, the pushing cylinder 51, the lifting cylinder 52°5
3 is in operation, and horizontal banding of the next six bottles by the arch horizontal packing machine 30 is in progress. In the first embodiment described above, a conveyor line for transferring bottles is stopped at the front of each packing machine to pack a plurality of bottles. A stopper that moves intermittently on the conveyor line from both sides of the horizontal and horizontal packaging machines forcibly stops the progress of each bottle on the line and packs them. The stopper is stopped from advancing and remains on the conveyor, and after packaging is completed, the stopper is moved back from the conveyor line, and the bottle after packaging is transferred to the horizontal packaging machine and the next process, and the other bottles are transferred to the horizontal packaging machine. Alternatively, the image may be transferred to the front of the image. Further, in the case of the second embodiment, the conveyor 22 located in front of the horizontal packaging machine 40 is configured with a free roller conveyor that is constantly driven or has an inclination toward the next process, and the conveyor line is formed on both sides of the horizontal packaging machine 40. A total of three stoppers are placed on the top that move intermittently and can come and go. That is, a first stopper is disposed on the rear side in the direction of travel of the conveyor line of the horizontal packing machine 40, and a second and third stopper is disposed on the front side of the conveyor line in the direction of travel of the horizontal packing machine 40 with an interval corresponding to the diameter of the bottle to be packed. , the first stopper prevents the plurality of bottles strapped horizontally from the horizontal packing machine 30 from advancing, and the second and third stoppers are placed on standby on the conveyor 22, and the second stopper to stop the bottles that have reached the armpit, and move the conveyor in the direction of travel 1.
Bands are hung perpendicularly to the cutting line and the second row, and when this packing is completed, the second stopper is retreated from the conveyor, and the plurality of bottles, each of which has been individually banded in the vertical direction, is carried up to the third stopper, that is, The plurality of bottles are moved until the second and third rows of the bottles are located within the vertical arch 42 in the direction of conveyor movement, and the second band hanging perpendicular to the armpits is used to pack the bottles. The third stopper is retracted to move the plurality of bottles hung vertically with two bands to the next process, and the first stopper is retracted to move the plurality of waiting bottles to the front of the horizontal packing machine. Then, the second and third stoppers, which are located on the front side of the conveyor line of the horizontal packing machine in the traveling direction and are spaced apart by the diameter of the bottles that are the objects to be packed, are advanced onto the line. In this case, the number of parts required for line control can be reduced, which is effective when the items to be packaged are of a standard type. Furthermore, in the embodiment described above, the bottles to be packed are arranged in three rows in the direction of movement of the conveyor line 20.
The conveyor line 20 is packed in units of 6 pieces in 2 rows in the width direction, and is configured so that bands are applied horizontally to the neck 11 and body 13, and bands are applied in the width direction of the conveyor line 20 at two locations between the neck 11. However, the number of bottles and the position of the straps can be changed as appropriate. For example, as shown in Figure 3, it is also possible to pack the bottles in units of four and the whole to be approximately rectangular. 11 and the body part 13, and then a cross-shaped band can be applied between the neck part 11 and perpendicular to the horizontal band. The complementary bottles 100, which are packed in a generally rectangular shape as a whole by the above-mentioned packaging system, are packed tightly together with the ribs 16 of the skirt 15 interlocking with each other at the time of delivery. 16, the band wound around the bottle body 13 and the band wound in the direction perpendicular to the bottle body 13 are respectively locked, ensuring that the entire package is approximately rectangular, and the band will not be damaged by vibration during shipping. It never comes loose. Therefore, the band is pulled out and falls along the bottle body or skirt, or each bottle is shifted in a diamond shape and the band is loosened, preventing the bottle from moving, reducing internal pressure increase due to vibration, and reducing the contact between each bottle. It can be delivered without causing damage due to etc. The plurality of bottles 100, which are packed in a generally rectangular shape by the above-mentioned packing system, can be stacked in an appropriate number of stages as shown in FIG. 2, respectively. That is, as shown in FIG. 7, the upper bottle 101
The neck 11 (cap 1B) of the lower bottle 102 is fitted into the recess 19 formed in the lower surface of the skirt 15 of the lower bottle 102.
7 is locked to the periphery of the opening of the recess 19 of the skirt 15 of the upper bottle 101. Therefore, loaded top bottle 1
The bottom surface of the 01 can be sufficiently protected, and the loading condition is stable and there is no chance of the load collapsing. When connecting the bottles manually, it is possible to carry a plurality of bottles packed in groups of 4 to 6 by grasping the band wrapped between the necks of the bottles. As shown in FIG. 3, the bands hung horizontally on the necks 11 of the plurality of bottles 100 are latched to the lower surfaces of the 7 lunges 17, and the bands hung between them are latched to the lower surfaces of the lip 16 of the skirt 15. Therefore, the band does not come off and the bottle does not fall during manual transportation.

As described above, the present invention includes a packaging container, a conveyor line for transporting the packaging container, and a packaging machine disposed between the conveyor lines, and the packaging container has a bottom, a body, and a body. A shoulder portion formed above, a neck portion having a smaller diameter than the body portion formed by projecting the shoulder portion upward, and a flange provided around the neck portion in the horizontal direction, and or a rib consisting of a continuous convex portion formed on a skirt surface having an inner diameter into which the bottom portion can be fitted, and the conveyor line is configured to transport a plurality of the packaging containers through the rib by an appropriate drive mechanism. comprising a belt and/or roller conveyor that abut each other and convey in an upright state, and the packing machine is arranged at the rear in the traveling direction of the conveyor line, and the packing machine is arranged between the flange and the shoulder of the plurality of packaging containers and/or in the horizontal direction of the body. an arch horizontal packaging machine that performs banding on the belt; or a horizontal packaging machine for hanging a plurality of bands, and a drive mechanism that can freely raise and lower the arch horizontal packaging machine and/or the plurality of packaging containers facing the arch horizontal packaging machine, It has become possible to perform packaging operations for multiple packaging containers on a single line.In other words, the convex ribs formed on the skirts of the packaging containers that are being transported on the conveyor line, such as bottles and other packaging containers, A plurality of bands can be packed tightly together in an interlocking state, and a band wound horizontally around the packaging container and a band wound in a direction perpendicular to this can be wrapped around the convex ribs, respectively. Therefore, the packaging container can be packed squarely and firmly without slipping or coming off. Therefore, during shipping, the ribs in the meshing state prevent the packaging from shifting due to vibration. , it is possible to reduce the influence of vibrations applied to the packaging container, prevent the packaging container from bursting due to the increase in pressure of the contents such as carbonated drinks, and it is possible to easily transport multiple packed packaging containers by hand. At the same time, it eliminates the need for wooden boxes or trays, which were traditionally required for shipping packaging containers.
It has become possible to save equipment costs, personnel costs, and labor for collecting and recycling these materials. Further, if a recess is formed at the center of the bottom of the skirt, deeper than the distance from the upper end of the packaging container to the upper surface of the flange, and having a smaller diameter than the flange and a larger diameter than the neck of the packaging container, the ! i! When loading, if the neck of the lower packaging container is fitted into the recess of the upper packaging container, the upper surface of the flange of the lower packaging container will come into contact with the periphery of the recess of the upper packaging container. It protects the bottom of the container and allows it to be loaded in a stable manner without collapsing. In addition, if the packaging container is formed into a streamlined shape from the shoulder to the neck, the horizontal band wrapped around the neck will not be caught by the shoulder, and the band at the neck will allow for more accurate packaging. becomes possible. In addition, if the packaging container is made of synthetic resin such as PET, it is lighter and more resistant to impact than one made of glass, so it is possible to package and ship a large number of packaging containers at once, which requires less manual transportation. It is possible to reduce damage to the container during delivery, and to prevent damage to the container during delivery. 1--゛-゛, ゛
