BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of stacking and stacking truncated cone-shaped containers such as cup-shaped containers which are stacked and stacked in multiple stages.

[0002]

2. Description of the Related Art A conventional frustum-shaped container stacking / stacking method and apparatus will be described with reference to FIGS. 3 to 5. FIG. 5 is a perspective view showing the entire truncated-conical container stacking / stacking apparatus. is there. In this frustum-shaped container accumulating / stacking device, while the frustum-shaped containers 10 are continuously supplied to the two-row supply conveyors 22 by the two-row carry-in conveyors 21, the cones supplied to the respective supply conveyors 22 are also supplied. The trapezoidal containers 10 are sorted into three rows by the sorting device 35 for each supply conveyor 22 (1
1), grouping them on the supply conveyor 22 and stacking them (see 11a), then joining both groups and guiding them to the bucket conveyor 23, where the partition sheets 33 supplied from the partition sheet magazine 32 are joined.
Are inserted between the upper and lower stages of the truncated cone-shaped containers 11a, and then the truncated cone-shaped containers 11a are filled by the filling device 24 into the corrugated cardboard sheets 26 supplied from the corrugated cardboard sheet magazine 25. Boxed molded product 2
After being molded into 7, it is carried out to the outside by a carry-out conveyor 31.

FIG. 3 is an explanatory view showing a general example of a stacking / stacking method for packing the truncated cone-shaped containers in the box without reducing the packing volume in the stacking / stacking apparatus. FIG. 3 (a)
When the frusto-conical container 10 is continuously supplied from the carry-in conveyor to the supply conveyor 2 as shown in FIG. 5, it is sorted into three rows, row A, row B, and row C by the sorting device (see 11). , And is conveyed by the supply conveyor 2.

Then, as shown in FIG. 3 (b), the three truncated cone-shaped containers 11 are sucked by the vacuum cups 6 of the stacking device 5 and placed at a predetermined position in the first stage. Next, the three frustoconical containers 11 in the second stage are sucked by the vacuum cup 6 of the stacking device 5 in the same manner as described above,
Moving to the right of (b), it is laid down on the partition sheet 7 placed on each truncated cone-shaped container 11 in the first stage, and the second stage is stacked on the first stage. It

FIG. 3 (c) shows another example of the stacking device. In this stacking device, the pushing lever 15 operates to the right, the three truncated cone-shaped containers 11 in the first stage are pushed to the right (see the dotted arrow), and supported by the cylinder 8 so as to be able to move up and down. It is placed on the table 9, the partition sheet 7 is placed on it, then the cylinder 8 operates in the contracting direction, the table 9 descends, and then the pushing lever 15 operates in the right direction in the same manner as described above, The three truncated cone-shaped containers 11 in the second stage are pushed rightward, placed on the partition sheet 7, and the second stage is stacked on the first stage.

FIG. 4 is an explanatory view showing a stacking / stacking method for packing the truncated cone-shaped containers in a box by reducing the packing volume. As shown in FIG. 4 (a), when the truncated cone-shaped container 10 is continuously supplied from the carry-in conveyor to the supply conveyor 2, the sorting device causes the three rows A, B and C to be separated.
It is sorted into rows and conveyed by the supply conveyor 2.

At this time, the truncated cone-shaped container 10 in the row B is
The reversing means B1 is turned upside down to form an inverted truncated cone shape in which the small diameter portion is on the upper side and the large diameter portion is on the lower side (see 12). That is, the row A is in the normal position (see 11), the row B is in the reverse position (see 12), and the row C is in the normal position (see 11). A stacking device (for example, FIG. 3B or FIG. 3) in which the truncated cone-shaped container 11 in the row A, the truncated cone-shaped container 12 in the row B, and the truncated cone-shaped container 11 in the row C on the supply conveyor 2 are not illustrated. As shown in FIG. 4B, the stacking device 3 (c) is used to stack the upper and lower layers.

In this case, the frustoconical containers in the first and second tiers are lined up in the lateral direction at the normal position, the reverse position, and the regular position, so that the lateral width becomes the minimum dimension. However, since the upper surface of the first step and the lower surface of the second step are in contact with each other, the contact part is damaged and the commercial value is reduced. In order to prevent this damage, it is conceivable to interpose a partition sheet 7 between the first stage and the second stage as shown in FIG. 3, but if this step is added, the cost of the entire apparatus becomes high. In addition, extra materials are required.

In FIG. 4C, when the truncated cone-shaped containers 10 are continuously supplied from the carry-in conveyor to the supply conveyor 2, the distribution device sorts them into three rows, row A, row B and row C. Then, it is conveyed by the supply conveyor 2. At this time, inversion means A1, B1 and C are provided for each column as shown.
By 1, the top and bottom of every other column is inverted so that the arrangement of each row is the normal position (see 11), the reverse position (see 12), the normal position (1
(See 1) ...

And, these truncated cone-shaped containers 11, 1
As shown in FIG. 4D, the stacking devices 2 and 11 are stacked by an unillustrated stacking device (for example, the stacking device shown in FIG. 3B or 3C). In this case as well, the frustoconical containers in the first and second stages are lined up in the horizontal direction at the normal position, the reverse position, and the normal position, so that the lateral width direction becomes the minimum dimension. Further, since the large-diameter lower surface of the first step and the large-diameter upper surface of the second step and the small-diameter lower surface of the first step and the small-diameter upper surface of the second step are in contact with each other, the contact portion is not damaged.

However, it is necessary to invert the truncated cone-shaped containers in each row and the adjacent row so that they are alternately arranged in the normal position and the reverse position, and the inversion control is complicated and there is a risk of malfunction.

[0012]

The above-mentioned conventional method of stacking and stacking truncated cone-shaped containers has the following problems. (1) When frustum-shaped containers are arranged in the same direction (normal position or reverse position) as shown in FIG. The packing volume of the shape container becomes large. (2) In the case of FIGS. 4A and 4B, since the upper and lower stages of the truncated cone-shaped container are aligned in the same direction (normal position or reverse position), the upper and lower surfaces of the truncated cone-shaped container are Contact
Damaged contacts. (3) In the case of FIGS. 4C and 4D, it is necessary to invert the truncated cone-shaped containers in each row and the adjacent row so as to be alternately arranged in the normal position and the reverse position, and the inversion control is complicated, There is a risk of malfunction.

The present invention is proposed in view of the above problems, and an object of the present invention is to improve the packing volume ratio of a truncated cone-shaped container, prevent quality deterioration during packing, and simplify reverse control. It is an object of the present invention to provide a method of accumulating and stacking frustoconical containers that can be made into a compact structure and can prevent malfunctions.

[0014]

In order to achieve the above object, the method of collecting and stacking truncated cone-shaped containers according to the present invention is such that a small-diameter portion is up and a large-diameter portion is down by a sorting means. The shaped containers are sorted into one row A, and the inverted frustoconical container with the smaller diameter portion and the larger diameter portion is sorted into the other row B, and then a plurality of truncated cone shaped containers in the row A are stacked. The first to move to the stacking position and to be arranged in a substantially V shape in plan view
The step and a plurality of inverted frustoconical containers in the row B are moved to the stacking position by the stacking means to form a space between the truncated conical containers arranged in the first step in a substantially inverted V shape in plan view. A second step of arranging, and a third step of moving a plurality of truncated cone-shaped containers in row A to a stacking position by a stacking means and placing them on the inverted truncated cone-shaped containers arranged in the second step. A predetermined number of truncated cones are passed through a fourth step of moving a plurality of inverted frustoconical containers in row B to a stacking position by stacking means and placing them on the truncated cone-shaped containers arranged in the first process. The feature is that shaped containers are accumulated and stacked in multiple stages.
