2. Description of the Related Art As a packaging material for articles, there is a carton formed of cardboard or the like. In this type of carton, as shown in FIG. 15, four plate materials p are formed into a rectangular tube shape with a fold line 1 interposed therebetween. Generally, a lid flap f and a bottom flap g that respectively close the opening portions at both ends are continuously provided on both end edges of the body portion b formed in FIG. 1. As shown in the figure, the bottom flap g is glued in advance. The so-called one-touch cart, in which the bottom flap g is naturally engaged with the bottom flap b to form the bottom, and the type in which the bottom flap is folded and glued during assembly (not shown) is there.

Until these cartons C are filled with articles, as shown in FIG. 16, the cartons C are folded in a flat plate shape with a pair of diagonal fold lines 1 formed on the body b. Transported and accumulated in.

When articles are packaged using such a carton C, as a carton C stacking device used in the packaging operation process, a device as shown in FIG. 17 is generally used. As shown in the figure, this stacking device 80 has four guide bodies 81 standing upright for guiding the corners of a carton C folded in a flat plate shape.
Carton C folded into a flat plate inside the guide body 81
It is designed to be stacked in the vertical direction while accumulating.

A locking claw 82 slightly protruding inward is provided at the lower end of the guide body 81 (see FIG. 18 (a)).
Is provided, and the lowest carton C is locked to the locking claw 82 so that the accumulated carton C is held.

Further, as a carton assembling device for taking out the cartons C thus accumulated in the accumulating device 80 and assembling the folded carton C, there is one as shown in FIG.

This assembling apparatus 90 attracts one of the plate members p constituting the body b of the lowest carton C stacked in the stacking apparatus 80, and raises and lowers the suction head 91. A pair of guide plates 92a, 92b which form a passage of the body part b of the carton C, which is arranged immediately below the stacking device 80 corresponding to the elevating means (not shown) and the plate material p sucked by the suction head 91. And a mounting portion 93 of the carton having a flat mounting surface disposed directly below the passage, and a pair of guide plates 92a,
The upper part of 92b is a plate material p not sucked by the suction head 91.
The guide plate 92b on the side is inclined upward so as to spread outward, thereby forming an upwardly extending introduction path, and at the bottom of the pair of guide plates 92a and 92b, the plate material p to which the suction head 91 sucks is barely bare. It is designed to form a passage of constant width that can pass through.

First, as shown in FIG. 18A, when the suction head 91 attracted to the lowermost carton C stacked in the stacking device 80 descends, only the lowermost carton C flexes slightly and the locking claws are engaged. It is removed from 82 and taken out from the collecting device 80.

Next, when the suction head 91 descends as it is, when the body part b of the carton C passes through the introduction path formed by the pair of guide plates 92a and 92b, as shown in FIG. The plate member p that is not attracted by the suction head 91 comes into contact with the upper inclined portion of the one guide plate 92b to raise the body part b of the carton C to some extent. After that, when the suction head 91 further descends, as shown in FIG. 7C, when passing through the passage of a constant width formed by the lower portions of the pair of guide plates 92a and 92b, the body portion b of the carton C is rectangular. Shaped, square tubular body b
Is formed.

When the suction head 91 is further lowered, the carton C is placed on the placing portion 93 with the body portion b formed in a rectangular tube shape.
When the suction state is released and the robot descends, the assembly of the body portion b of the carton C is completed, as shown in FIG.

[0011]

When a carton of the type in which the bottom flap is folded and glued at the time of assembling is assembled using the carton assembling apparatus 90 as described above, the flat carton is guided. Board 9
Although it is possible to assemble the carton body into a rectangular tube shape by passing it through the passage formed by 2a and 92b, the carton's opening shape is completely flat because it is slightly distorted due to creases. Cannot be kept in a rectangular shape, and when the bottom flap is folded and glued in the next step, it is held in a state in which the opening shape of the body does not become a perfect rectangle, making it difficult to fill the article in the article filling step. There is a problem that problems such as

Further, in the one-touch carton as shown in FIGS. 15 and 16, as described above, the engaging portions of the bottom flaps g, which are pre-glued, are finally meshed with each other so that the body portion b is finally obtained. Although a bottom is formed on the bottom, the engaging portions do not engage with each other only by raising the body portion b from a flat plate state to a rectangular shape, and the body portion b is slightly flattened in the opposite direction from the rectangular state. The joints are engaged. Therefore, the assembling apparatus 9 as described above
When 0 is used to assemble the carton C, there is a problem that the bottom of the body b is not completely formed and the carton C cannot be completely assembled.

Therefore, an object of the present invention is to provide a carton assembling apparatus which can surely raise the body of the carton in a rectangular shape and can sufficiently assemble a one-touch carton.

The support member 31 is arranged so as to block the transport path of the stacking unit 10 at the take-out position β of the carton 70. As shown in FIG. A cutout portion 31a is formed in a portion corresponding to the partition body 12 so as to pass therethrough. Therefore,
The partition body 12 can be circulated through the cutout portion 31a, and the cartons 70 stacked in the upright state in the stacking portion 10 are blocked by the support member 31 in the transport path. Further, the height of the support member 31 may be appropriately determined based on the smallest carton 70 so that it can correspond to other types of cartons 70.

The pressing claw 32 and the pressing plate 33 are supported as a whole so as to be able to move up and down on a column 35 which is erected in front of the take-out position β of the carton 70, and is driven to move up and down by an actuator. Further, the pressing claw 32 is supported in front of the pressing plate 33 so as to be able to move forward and backward, and is also supported so as to be able to move up and down independently, and is driven to move forward and backward and is moved up and down by an actuator. As described above, the pressing plate 33 holds the pressing carton 70 so that the front carton 70 does not fall when the pressing claw 32 is inserted between the cartons 70. By providing it, there is an advantage that the inserting operation of the pressing claw 32 into the carton 70 can be performed smoothly, but it is not always necessary to provide.

In the air blowing device 34, the air blowing nozzle 34a is arranged in front of the take-out position β of the carton 70 so that the air can be blown out obliquely forward in the traveling direction of the stacking unit 10. Has become.

As shown in FIG. 1, the assembling device 2 is arranged on the side of the take-out position β of the carton 70, following the stacking device 1, and the carton 70 for taking out the carton 70 at the take-out position β of the carton 70. It is composed of a take-out means 40, a conveyor 50 for carrying the carton 70 taken out by the take-out means 40 to the next step, and a locking member 60 provided on the conveyor 50.

The take-out means 40 is shown in FIG. 1, FIG. 4 and FIG.
As shown in FIG. 3, a slide rail 41 disposed on one side of these from the stacking device 1 to the conveyor 50, and a column 43 erected on the slide rail 41 via a slider 42 so as to be able to move forward and backward. An arm 45 horizontally supported by the column 43 via a slider 44 and extending horizontally toward the stacking device 1 and the conveyor 50; and a body of a carton 70 attached to the tip of the arm 45. The suction head 46 is attached to the suction head 71, an actuator (not shown) that drives the sliders 42 and 44, and control means (not shown) that controls these actuators. It can move freely in the vertical direction and the front-back direction. Details of drive control of the suction head 46 by the control means will be described later.

The conveyor 50, as shown in FIG.
It is provided with four conveyor belts 51 functioning as a mounting surface of the carton 70, and after the carton 70 is assembled on the upper surface of the conveyor belt 51 by the take-out means 40, the next step is an article filling station. The carton 70 is transported to. Since the conveyor 50 is a well-known belt conveyor that is generally used, detailed description of its configuration will be omitted.

The locking member 60 is supported by the flat bar 61, which is disposed on the conveyor belt 51 with a slight gap so as to be orthogonal to the conveyor belt 51 of the conveyor 50. And a guide plate 62. The guide plate 62 rises obliquely upward toward the stacking device 1 side.

Next, a series of steps from stacking to assembling of the carton 70 will be described together with detailed operations of the stacking apparatus 1 and the assembling apparatus 2. As described above, in the stacking device 1, since the plurality of stacking sections 10 partitioned by the plurality of partition bodies 12 are cyclically moved from the supply position α of the carton 70 to the extraction position β, the stacking device 1 is provided at the supply position α. The carton 70 is supplied to the stacking unit 10 by a worker or a carton supplying device. At this time, the carton 70 is oriented so that the fold line 72 of the body 71 is horizontal as shown in FIG. Further, a plurality of cartons 70 can be supplied to one stacking unit 10 formed by the two partition bodies 12. However, in order to take out the carton 70 smoothly, one stacking unit 10 is required.
It is desirable to set the number of supply so that a certain amount of gap is generated between the cartons 70 inside.

Carton 70 supplied to the stacking unit 10
Moves to the take-out position β side on the plate 11 with the movement of the partition body 12, and when the first carton 70 is detected by the sensor 29, the conveying means 20 stops. Here, as shown in FIG. 6A, first, the air blow device 34 operates to blow out air from the blowout nozzle 34a, and disperse the carton 70 near the take-out position β.

Next, as shown in FIG. 3B, the pressing claw 32 and the pressing plate 33 are lowered so that the pressing plate 33 is pressed by the pressing claw 3.
The carton 70 at the rear of 2 is pressed from above to maintain that state. At this time, since the pressing claw 32 is located above the pressing plate 33, only the pressing plate 33 presses the carton 70. Following this, the pressing claws 32 descend and are inserted between the cartons 70, as shown in FIG. Then, as shown in FIG. 7A, the pressing claws 32 inserted between the cartons 70 move forward to press the cartons 70 against the support member 31. As a result, the carton 70 to be taken out which is located at the leading edge is positioned.

At this point, the suction head 46 of the take-out means 40 stands by at a position facing the uppermost plate member 71d of the body 71 of the positioned carton 70, as shown in FIG. The suction head 46 is in the carton 70
It horizontally moves to the upper side and is adsorbed to the uppermost plate member 71d of the body 71. At this time, as described above, since the carton 70 is pressed against the support member 31 by the pressing claw 32, the carton 70 is completely positioned and the suction by the suction head 46 is surely performed. Then, as shown in FIG. 3C, when the suction head 46 moves upward while being sucked by the carton 70, the most advanced carton 7 at the take-out position β is detected.
Only 0 is taken out of the integrated device 1. When the carton 70 is taken out, the pressing claw 32 and the pressing plate 33 are returned to the initial positions to prepare for taking out the next carton 70.

When suction by the suction head 46 to the carton 70 is hindered for some reason, an increase in suction pressure of the suction head 46 (decrease in negative pressure) is detected by a pressure sensor (not shown). Therefore, based on this detection signal, the control means reversely drives the servo motor of the transport means 20 to temporarily retract the stacking unit 10 by a predetermined amount, and then repeats the above-described steps.

The carton 70 thus taken out of the stacking device 1 is subsequently assembled by the assembling device 2. First, when the arm 45 of the take-out means 40 moves upward with the carton 70 adsorbed, as shown in FIG.
As shown in FIG. 5, the suction head 46 also rises accordingly, and the carton 70 is completely extracted from the stacking device 1. Then, in the direction indicated by the arrow in FIG.
Move horizontally, and as shown in FIG.
The suction head 46 that has adsorbed is also moved above the conveyor 50. At this time, the carton 70 sucked by the suction head 46 is in a state in which its body portion 71 is slightly opened.

When the column 45 moves further forward by a predetermined amount while the arm 45 descends along the column 43, the suction head 46 moves in the direction shown by the arrow in FIG. As shown, the body 71 of the carton 70
The corner portion at the lowest position abuts on the conveyor belt 51 near the flat bar 61. At this time, depending on the opening degree of the body 71 of the carton 70, the corner of the body 71 comes into contact with the guide plate 62, and the guide 62 naturally causes the corner of the body 71 to come close to the flat bar 61. Be guided. Therefore, although the guide plate 62 is not always necessary, it is preferable to provide it.

From this state, the arm 45 is further moved to the column 4
When descending along 3, the suction head 46 also descends accordingly, gradually opening the body 71 of the carton 70,
Finally, as shown in FIG. 2B, the carton 70 is placed on the conveyor belt 51 in a state where the body portion 71 is formed in a rectangular rectangular tube shape. At this time, the body portion 71 is formed to have a rectangular tubular shape, but the engaging portions 77a and 77b of the bottom flaps 75a and 75b of the carton 70 described above are not meshed with each other, and the bottom of the carton 70 is completely closed. It has not been formed.

Then, when the column 43 is finally retracted slightly, the suction head 46 presses the rectangular tube-shaped body portion 71 against the flat bar 61 as indicated by the arrow in FIG. -Shaped body 71 is slightly flattened on the opposite side and becomes flat, and at the same time the bottom flap 75 of the carton 70 is
Engagement portions 77a and 77b of a and 75b are completely engaged with each other to form a bottom, and the assembly of the carton 70 is completed. When the assembling of the carton 70 is completed, the suction head 46 releases the suction state to the carton 70, returns to the initial position, and prepares for taking out the next carton 70.

As described above, this carton stacking device 1
Since the stacking unit 10 is formed by a plurality of partition bodies 12 and the flat carton 70 is erected horizontally in the stacking unit 10, the kind and size of the carton are changed to some extent. Can be sufficiently dealt with, and the state of stacking cartons does not become unstable unlike the conventional type stacking device that stacks stacks vertically.
Large quantities of cartons can be accumulated at one time.

At the take-out position β of the carton 70, since the carton 70 is reliably positioned at the take-out position β by the take-out assisting means 30, the suction head 46 of the take-out means 40 of the carton 70 sucks the carton 70 onto the carton 70. The operation is reliably performed, and the carton 70 can be taken out smoothly.

Further, the assembling apparatus 2 has the suction head 46.
The corner portion of the body portion 71 of the carton 70 adsorbed by the above is lowered while abutting on the conveyor belt 51 of the conveyor 50 to form the body portion 71 in the shape of a rectangular tube and the body portion formed in the shape of a rectangular tube. 71 further flat bar 6
The bottom flaps 75a, 7a of the carton 70 are pushed down to the opposite side by pressing 1 to flatten them.
Since the engaging portions 77a and 77b of the 5b are intermeshed with each other, the carton 70 can be reliably assembled. Furthermore, if the type or size of carton changes,
Since it suffices to change the program of the control means for controlling the movement of the suction head 46, the versatility is improved, and the labor for setup change is reduced, and the work efficiency is improved.

In the stacking apparatus 1 according to this embodiment, the stacking unit 10 is formed by the fixed plate 11 and the plurality of partition bodies 12 moving along the plate 11. For example, each stacking unit 10 It is also possible to provide a bottom plate for each and to circulate and move the bottom plate together with the partition body 12. In addition, in this embodiment, the stacking unit 10 is circularly moved in the vertical direction between the supply position α and the take-out position β of the carton 70, but the present invention is not limited to this, and, for example, circulation on a horizontal plane. It can also be moved.

Further, the take-out device 2 assembles the carton 70 on the conveyor belt 51 of the conveyor 50. For example, an assembling table having a locking member attached to the mounting surface of the carton is separately provided. Cartons can also be assembled on the assembly table. Further, although the take-out device 2 drives the suction head 46 so as to bring the carton 70 into contact with the conveyor belt 51 in the vicinity of the locking member 60, the carton 70 is moved away from the locking member 60. The body 71 is once abutted to form the body 71 into a rectangular tube shape, and then the suction head 46 is further moved horizontally to fix the body 71 of the carton 70 to the locking member 60.
You may make it contact | abut and press.

[0049]

As described above, the assembling apparatus of the present invention is
In a position above the mounting surface, the plate material adsorbed is substantially at a right angle to the mounting surface, from the state in which the plate member is supported in a posture such that the plate material is far from the mounting surface, While keeping the posture, the suction head is brought close to the placing surface, the attracted plate material is brought into contact with the placing surface, and then the other plate material of the body portion facing the attracted plate material is Since the stopper member is brought into contact with and slightly pushed to the stopper member side, the body portion is formed into a rectangular tube shape when the plate material attracted to the suction head is brought into contact with the mounting surface. By further abutting the locking member and slightly pressing it toward the locking member, the crease is eliminated, and in the one-touch carton, the engaging portions of the glued flaps on the bottom side are mutually engaged. Engages with the bottom to ensure a bottom is formed on the body.

Therefore, when the carton is assembled by the assembling apparatus of the present invention, the problem that the product is difficult to be filled in the process of filling the product is solved and the one-touch carton can be assembled sufficiently. It is possible and versatility is enhanced.
