[0005]
Next, the operation of the cardboard caser 100 will be described. First, FIG. 12 shows an example of a cardboard box 90 to be box-formed. The corrugated cardboard 90 is a so-called A-shaped corrugated cardboard. As shown in a developed view of FIG. 3A, an inner flap 94 and an outer flap 92 are provided on both sides of a side surface 93, and a joint 95 is provided on one end. Is provided. The assembled state of the cardboard 90 is shown in FIG. With the cardboard 90 assembled, the bottom side of the cardboard 91 is closed with the inner flap 94 folded inside and the outer flap 92 folded outside. On the other hand, the upper part of the corrugated cardboard 91 is similarly folded and closed in the order of the inner flap 96 and the outer flap 97.
[0006]
First, in the box making device 1, the cardboard 90 that is folded flat and stands up is stored, taken out, and set up on the conveyor 6 of the sealing machine 2. The cardboard 91 set up is transferred to the filling conveyor 7 while the inner flap 94 at the bottom is folded and the outer flap 92 is folded slightly inward while being sequentially conveyed. FIG. 13 is an explanatory diagram showing a process leading to an integrated filling device. The manufactured cardboard 91 is conveyed by the conveyor 6, and the inner flap 94 in the conveying direction is folded at the entrance 35 of the stacking and filling device 3. The inner flap 94 in the direction opposite to the transport direction is folded by the separately provided actuator 36, and is positioned at a predetermined position on the filling conveyor 7 in that state.
[0007]
In the filling conveyor 7, the products are accumulated by the accumulation filling device 3, and the accumulated products (integrated products S) are stored in the corrugated cardboard 91 produced. Specifically, in the accumulating and filling apparatus 3, products are supplied from the supply conveyor 5, and these products are accumulated in, for example, four rows and three rows.

Subsequently, the inner flap 96 in the upper conveying direction of the cardboard 91 is folded by the inner flap fold 38 provided above the conveyor 6, and the inner flap 96 in the direction opposite to the conveying direction is folded by the inner flap fold 39 driven by the actuator. Then, the outer flap 97 is folded by the outer flap fold 40, and the packing is completed.
[0010]
[Problems to be solved by the invention]
However, in the conventional cardboard caser 100 described above, since the lower plate 31 is inserted into the cardboard 91 through the space 98 between the inner flaps 94, the dimensions of the lower plate 31 are different from those of the inner flap 94 and the inner flaps. There is a problem that the space 98 is restricted by the space 98 with the space 94 and cannot be made larger than the space 98, so that it is difficult to hold the integrated product S reliably.
[0011]
Then, this invention was made in view of the above, and an object of this invention is to provide the packing apparatus and packing method which can support reliably by a lower plate, and a cardboard.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, a packing device according to the present invention sandwiches an object to be packed between an upper holding member and a lower holding member, and turns the object to be packed into a cardboard in a state in which a bottom inner flap of the cardboard is substantially closed. At the same time, the lower holding member has a size larger than the size of the corrugated cardboard when the inner flap is closed, and a notch is provided in the inner flap of the corrugated cardboard at a portion where the lower holding member and the inner flap interfere with each other. It is characterized by having.
[0013]
That is, in the related art, the notch is formed on the inner flap side in accordance with the lower holding member having a dimension that interferes with the inner flap, whereby the object to be packed can be reliably held by the lower flap. In addition, the shape of the lower holding member is not limited to the plate shape, and various changes can be made according to an object to be packed as shown in the following embodiment, and the cutout shape of the inner flap is changed according to the shape. Is done. It is sufficient that a notch is provided at least in the interference portion, and it does not prevent the notch from being provided more than that.
[0014]
The packing device according to the next invention sandwiches the object to be packed between the upper holding member and the lower holding member, and puts the object to be packed into the cardboard while the inner flap on the bottom side of the cardboard is substantially closed, and the lower holding member is The size of the cardboard is larger than the size of the opening when the inner flap is closed, and a small flap is provided on the inner flap of the cardboard at a portion where the lower holding member interferes with the inner flap. It is characterized.
[0015]
That is, by providing the small flap in a portion that interferes with the lower holding member of the inner flap, even if the lower holding member interferes, the small flap is released by the flap operation. This makes it possible to reliably hold the object to be packed by the lower flap. In addition, the shape of the lower holding member is not limited to the plate shape, and various changes can be made according to the packing object as shown in the following embodiment, and the shape of the small flap is changed according to the shape. .
[0016]
The packing device according to the next invention is characterized in that, in the above configuration, when the object to be packed is further put into the cardboard, the container is in a semi-closed state in which the lower holding member can pass the outer flap on the bottom side of the cardboard. . That is, by setting the outer flap in a semi-closed state, it is easy to pass through the lower holding member, and it is difficult for the packing object stored from above the cardboard to fall down.
[0017]
In the packing device according to the next invention, in the above configuration, the lower holding member has a T-shaped cross section having a support portion, and the gap between the outer flaps is closed in a state where the outer flap on the bottom side of the cardboard is closed. The support portion of the lower holding member passes through, and the lower holding member comes off to the side of the cardboard.
[0018]
That is, although the lower holding member is supported by the support portion, when the outer flap is closed, the support portion is sandwiched between the outer flaps and can be moved only in the space direction. In addition, the lower holding member has a notch in the inner flap through which the lower holding member passes, and the lower holding member can be positioned in the vertical direction between the outer flap and the inner flap. Then, the supporting portion is moved together with the lower holding member in the spacing direction, and the lower holding member is pulled out to the side of the cardboard because the outer flap is opened in the same direction.

Accordingly, the size of the lower holding member can be increased, so that the object to be packed can be securely held and packed in cardboard.
[0021]
In the packing method according to the next invention, in the above configuration, when the object to be packed is further put into the cardboard, the flap on the bottom side of the cardboard is kept in a semi-closed state such that the lower holding member can pass through, and further, the lower holding The member has a T-shaped cross section having a support portion, and after the object to be packed is put in cardboard, the outer flap is closed, and in this state, the gap between the outer flap and the outer flap is supported by the lower holding member. The portion passes, and the lower holding member is pulled out to the side of the cardboard.
[0022]
That is, when the lower holding member is moved upward, the outer flap of the cardboard is kept in a semi-closed state, and the lower holding member is passed during this time. Then, when putting the object to be packed into the cardboard, the lower holding member is not completely retracted from the inside of the cardboard, and the outer flap is closed and packed. The lower holding member moves between the inner flap and the outer flap as the support moves in the gap between the outer flap and the outer flap, and is pulled out to the side of the cardboard. Thus, the object to be packed can be packed in a cardboard without the lower holding member interfering with the inner flap.
[0023]
The corrugated cardboard according to the next invention is characterized in that the cardboard is vertically opened, has at least two inner flaps on the bottom side, and a cutout is provided in the inner flap at a portion where the lower holding member of the packing device interferes.

Thereby, the integrated product S is accommodated in the cardboard 99 together with the upper plate 26 and the lower plate 31. After storing the integrated product S in the cardboard 99, the upper plate 26 is retracted upward.
[0028]
In addition, as shown in FIG. 14, the lower plate 31 is lowered to a position slightly lower than the inner flap 94 by being lowered, and is located between the inner flap 94 and the outer flap 92. Then, the outer flap 92 is gradually folded by the outer flap fold 37, but the cylinder shaft 33, which is the support portion of the lower plate 31, relatively moves in the gap 92s between the outer flap 92 and the outer flap 92, and When the lower plate 31 moves relatively in the gap 94s between the outer flap 92 and the inner flap 94, the lower plate 31 is pulled out from the open side rear of the outer flap 92. This allows the lower plate 31 to be extracted while the integrated product S is supported by the lower plate 31 to some extent or even when the outer flap 92 is folded.
[0029]
FIG. 3 is an explanatory diagram showing a modified example of the cutout portion. As shown in FIG. 7A, the lower plate 61 serving as the lower holding member may have an H shape, and two notches 62 may be formed for each inner flap 94 in accordance with the lower plate 61. Further, as shown in FIG. 7B, the lower holding member may be formed in an X shape constituted by a rod-shaped member 63. The notch 64 is formed obliquely so that the X-shaped bar 63 does not interfere. Further, as shown in FIG. 3C, the lower plate 65 may be formed in a Z shape, and the cutout portion 66 may be bent so that the Z shape lower plate 65 does not interfere. These are suitable for dispersing and supporting the supporting portions, for example, when the number of integrated products S is large. Further, as shown in FIG. 3D, the lower plate 67 may be formed in a track shape, and the cutout portion 68 may be formed in an arc shape.
[0030]
Further, as shown in FIG. 4, in the case of a corrugated cardboard 99 in which the inner flaps 94 alternately overlap, a hole-shaped notch 70 through which the lower plate 31 passes may be provided in one of the inner flaps 94. In this case, one inner flap 94 is closed, and the lower plate 31 is moved up and down through the cutout 70. After the integrated product is put in the cardboard 99, the other inner flap 94 is bent so as to cover the cutout 70.
[0031]
By doing so, the supporting portion of the lower plate 31 can be enlarged, so that the integrated product S can be reliably held without interfering with the inner flap 94.
[0032]
(Embodiment 2)
FIG. 5 is an explanatory diagram illustrating a packing device according to Embodiment 2 of the present invention. The present invention is characterized in that the small flap 71 is provided on the inner flap 94 on the bottom side of the cardboard 70. The small flap 71 is provided at a portion where the lower plate 31 interferes with the inner flap 94, and specifically, as shown in the figure, the small flap 71 is bent at a portion facing the short side of the lower plate 31 as a node. ing. When the lower plate 31 moves up, the small flap 71 is pushed up (not shown), and when the lower plate 31 moves down, the lower plate 31 pushes down the small flap 71. The formation of the small flap 71 only needs to make a cut 72 at a predetermined position of the inner flap 94. In addition, even if the cut 72 is not made, the entire end of the inner flap 94 may be a small flap 73 as shown in FIG. Even if the small flaps 71 and 73 as described above are used, the size of the lower plate 31 can be increased, so that the integrated product S can be reliably held.
[0033]
In addition, as the above-mentioned integrated products S, there are bag-packed products, boxed products, and the like, and almost all products can be packed. The present invention is not limited to the A-shaped corrugated cardboard, but the present invention is applicable to other types of corrugated cardboard. In other words, if there is a flap on the bottom side of the corrugated cardboard and the lower plate is enlarged to hold the integrated product, if the lower plate and the flap cause interference, the flap should be provided with a notch for preventing interference. Thus, the present invention can be suitably realized.
