Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for automatically covering a case body 1 having a side wall 1a with a lid 2 having a side wall 2a partially overlapping with the side wall 1a.

[0002]

2. Description of the Related Art When a case body having a side wall is automatically covered with a cover body having a side wall partially overlapping with the side wall, the cover body is rotated with a chamfered portion of a corner bent portion of the case body as a fulcrum. There is a technology to do so. Further, as an apparatus for carrying out the method, a fixing means for holding the case main body with the chamfered corner bent portion at a predetermined position,
There is known one provided with a lid body holding means for holding a lid body having a side wall that overlaps a side wall portion of the case body and rotating the case body around a corner bending portion of the case body (for example, Japanese Patent Laid-Open No. Hei 10 (1999) -264242). No. 05-147604).

In the above-mentioned prior art, the lid body is covered with the lid body by rotating the lid body. That is, the lid body is rotated with the chamfered portion of the corner portion as a fulcrum in a fixed state of the case body.

[0004]

As described above, in the conventional method in which the cover body is covered with the cover body by rotating the cover body, the case body and the cover body are as flexible as those of the resin molded product. If it is made of something, there will be no problem, but if it is made of something that is not strong like paper, it is likely that both the case body and lid are deformed. Therefore, the cover cannot be reliably covered only by rotating the cover with respect to the case body.

Further, in the above-mentioned prior art, on the premise that the case body and the lid body are resin molded products, a method of holding only one side of both sides of the lid body is adopted. If the case body and lid are resin molded products, it is sufficient to hold only one of the two sides of the lid, but if they are made of something that is not as rigid as when made of paper. However, if only one of the both sides of the lid body is held, the lid body is easily deformed, and the case body cannot be covered well.

In particular, when the case body and the lid are made of a non-rigid material such as paper, and when the case is used as a carrying box, after the product is transported. Of the box, at least the lid is not bulky by bending the part that should become the side wall at its four peripheral edges, as shown in a of FIG. 1, a ₀ of FIG. 2 and a, b of FIG. It is folded in a sheet shape, a number of these are stacked and carried, and they are reassembled for use, and four side walls are raised from the four peripheral portions as shown in FIG. 1b, FIG. 2b and FIG. 3c, It is used again as a lid. Although not shown, the case body is a so-called assembling type, and after transporting the product, it is unfolded and folded into a sheet-like shape that is not bulky, and a large number of these are stacked and carried. C, four side walls are formed as shown in FIG. 2c, and they are used again as the case body.

As described above, in the case where the case body 1 and the lid body 2 are made of a material that is not stiff like in the case of paper, and when the case body 1 and the lid body 2 are used as a box to pass through them, At least the lid 2 has a so-called crease, and it is difficult to keep the lid in a regular shape as shown in FIG. 1b and FIG. 3c. Therefore, when the case body or the lid is a synthetic resin molded product. There is a problem in that it is particularly difficult to cover the case body 1 with the lid body 2 as compared with the above. For example, due to the above-mentioned crease, the lid 2
It is difficult to vertically hold the four side walls of the top plate 2c, and it tends to bend inward. Even if the cover body 2 is put on the case body 1 in this state, the side wall bent inward is the case. It cannot be properly covered by being caught on the four peripheral walls of the main body 1.

In the case where the case body 1 and the lid body 2 are made of a non-rigid material such as the case of paper, and when the case body is used as a box to pass through, the case body is Comparing the strengths of 1 and the lid body 2, since the case body 1 must contain an article (usually a product in most cases), it is usually stronger than the lid body 2 in terms of strength. On the other hand, since it is enough to cover the case body 1 with the cover body 2, there is almost no problem even if the lid body 2 is weaker in strength than the case body 1. Therefore, the lid body 2 is usually weaker in strength than the case body 1, and thus the method of moving the lid body 2 weak in strength and covering the case body 1 is difficult to adopt. is there. If this method is adopted, the above-mentioned problems will occur in covering the lid.

In the present invention, the case body 1 can be surely covered with the lid 2 even in such a case. That is, the present invention is directed to the side wall 2 of the lid body 2.
After engaging a with the side wall 1a of the case body 1, by moving the case body 1 upward, the case body 1
The lid 2 is put on the cover. Then, the case body 1 is moved to the case body 1 with respect to the lid body 2 held from both sides, not limited to the relative movement between the lid body and the case body. By covering the body 2, the case body 1 can be reliably covered with the lid 2.

[0010]

According to the method of the present invention, a lid body 2 having a side wall 2a which partially overlaps a side wall 1a of a case body 1 is tilted and brought close to the side wall 1a of the case body 1, and the lid body is closed. The side wall 2a of 2 is engaged with the side wall 1a of the case body 1, and then the case body 1 is moved upward,
Thus, the case body 1 is covered with the lid 2.

In the above case, the lid 2 is moved and the case body 1 is moved while holding the two sidewalls 2b, 2b of the lid 2 which are continuous with the sidewall 2a and are orthogonal to the sidewall 2a. Good to do.

By positioning the holding plates 4a and 4a so as to contact the inner surfaces of the two side walls 2b and 2b of the lid body 2, the two side walls 2b and 2b are held, and both holding plates 4a and 4a are held. It is preferable to move the case body 1 to the farthest position from the side wall 2a along the two side walls 2b, 2b, and then move the case body 1 upward.

Further, in the device of the present invention, of the four circumferences of the lid body 2 having the side wall 2a which partially overlaps the side wall 1a of the case body 1, the two side walls 2b and 2b which are continuous with the side wall 2a and which are orthogonal thereto. To hold the lid body 2 at least in a tilted state, and to move the lid body 2 forward, the pair of left and right holding bodies 4 and 4 are located below the both holding bodies 4 and 4. It is characterized by comprising a holding table 11 for moving the case body 1 upward from a predetermined position.

It is preferable to provide means for rotating the holding bodies 4 and 4 so that the pair of holding bodies 4 and 4 is in a horizontal state.

It is preferable that the pair of left and right holders 4 and 4 are constituted by holding plates 4a which are in contact with the inner surfaces of the two side walls 2b and 2b of the lid 2.

A pressing member 9 for pressing the lid body 2 supported by both holding bodies 4 and 4 may be arranged between the pair of left and right holding bodies 4 and 4.

[0017]

As shown in FIG. 1d, the side wall 1 of the case body 1
When the lid body 2 having the side wall 2a that partially overlaps a is brought close to the side wall 1a of the case body 1 in the tilted state (in the direction of the arrow in the figure), the side wall 2a of the lid body 2 is shown as e in FIG. Engages with the side wall 1a of the case body 1. After that, the case body 1 is moved upward as indicated by an arrow in FIG. Then, as shown by f in FIG. 1, the lid body 2 can be automatically covered on the case body 1.

In this case, when the two side walls 2b, 2b of the lid body 2 which are continuous with the side wall 2a and orthogonal to the side wall 2a are held, the lid body 2 and the case body 1 are moved. The two side walls 2b, 2b do not bend inward.

In particular, the two side walls 2b, 2b of the lid body 2
When the two side walls 2b, 2b are held by positioning the holding plates 4a, 4a so as to contact the inner surfaces of the two side walls 2b, 2b, the two side walls 2b, 2b cannot be bent inward by the both holding plates 4a, 4a. No, both holding plates 4
Since a and 4a can be located between the side walls 1b and 1b of the case body 1 and the side walls 2b and 2b of the lid body 2,
The two side walls 2b, 2b of the lid body 2 can be reliably positioned outside the two side walls 1b, 1b of the case body 1. Then, from this state, the pair of left and right holding plates 4a,
When 4a is moved to the position farthest from the side wall 2a along the two side walls 2b, 2b, the movement causes the two side walls 2b, 2b of the lid body 2 to move to the side of the case body 1.
The side walls 2a while being positioned outside the two side walls 1b, 1b
Can be further engaged with the side wall 1a of the case body 1. After that, when the case body 1 is moved upward,
It is possible to cover the case body 1 with the lid body 2 automatically and surely.

Further, in the apparatus of the present invention, d of FIG.
As shown in, the case body 1 is placed on the holding table 11. The pair of left and right holders 4 and 4 has a lid body 2 having a side wall 2a that partially overlaps the side wall 1a of the case body 1.
Of the four rounds of 2 which are continuous with the side wall 2a and orthogonal thereto
The two side walls 2b and 2b are held, and the lid 2 is supported at least in a tilted state. Next, when both holding bodies 4 and 4 are moved forward from the state shown in FIG. 2d as shown in FIG. 2e, this lid body 2 can be stably moved with respect to the case body 1. In this state, when the holding table 11 is moved upward as shown by f in FIG. 2, the case body 1 placed on the holding table 11 can be automatically covered with the lid body 2.

When a means for rotating the holding bodies 4, 4 so that the pair of left and right holding bodies 4, 4 is in a horizontal state is provided, a folded sheet as shown in FIG. 2a. 2 is supported by the holding bodies 4 and 4 in a horizontal state, and the holding bodies 4 and 4 are operated from that position as shown in FIG. 2b, 2b
The part can be automatically raised to a regular shape.

When the pair of left and right holders 4 and 4 are constituted by holding plates 4a which are in contact with the inner surfaces of the two side walls 2b and 2b of the lid body 2, they are held on the inner surfaces of the two side walls 2b and 2b of the lid body 2. The plates 4a and 4a can be positioned so as to be in contact with each other, and the two side walls 2b and 2b are not bent inward by the two holding plates 4a and 4a, but also the two holding plates 4a and 4a.
Since a and 4a can be located between the side walls 1b and 1b of the case body 1 and the side walls 2b and 2b of the lid body 2,
The two side walls 2b, 2b of the lid body 2 can be reliably positioned outside the two side walls 1b, 1b of the case body 1.

When the pressing member 9 is disposed between the pair of left and right holding bodies 4 and 4, the pressing member 9 is attached to the top plate portion 2c of the lid body 2 supported by the holding bodies 4 and 4. Since the cover body 2 is pressed down, it is possible to prevent the lid body 2 that is about to cover the case body 1 from floating.

[Example] An example of a method of covering the case body with a lid,
Description will be given mainly based on FIG. 1 of the accompanying drawings. Figure 1
It is a perspective view which shows in stages the whole process of the method of covering the case main body 1 with the cover 2. In addition, FIG. 3 shows a case where a sheet-like lid body which is not bulky is formed by bending a portion which should be a side wall at the four peripheral edge portions, when viewed from the front side and the back side, and when the four side wall portions are raised from the four peripheral edge portions. It is a perspective view showing the case where it is formed.

As shown in FIGS. 3 (a) and 3 (b), the lid is often folded or assembled, as described above, when it is used as a box through which the lid is passed. At least the lid of the box of FIG.
A, FIG. 2 a _0, and FIG. 3 a, b, bend the part that should become the side wall at its four peripheral edges and fold it into a non-bulky sheet, and carry it by stacking it in large numbers. At this time, it is reassembled and, as shown in FIG. 1b, FIG. 2b and FIG. 3c, the four side walls are raised from the four peripheral edge portions and used again as a lid.

A large number of lids folded into a non-bulky sheet are stacked in a magazine 3 as shown in FIG. 2 and taken out one by one while finally undergoing the steps described below. Cover the body 1. It should be noted that the sheet-like lids that are stacked in large numbers in the magazine 3
To take out one by one, for example, it is possible to use an adsorption device such as a suction cup.

The four side walls of the lid in the folded state taken out from the magazine 3 are raised from the four peripheral edge portions, as shown in FIG.
B, the normal shape as indicated by 2 in FIG. 2b. Then, while keeping this shape, the case body 1 is finally covered by the following steps. Next, the operation of the embodiment of the method of covering the case body with the lid will be described with reference to FIG.

A lid 2 having a shape as shown in FIGS. 1b and 2b is held horizontally, and a case body 1 is positioned below the lid 2 (see FIG. 1c). Then, the lid 2 is tilted so that the side wall 2a side is lowered as shown by an arrow in c of FIG. 1 (see d of FIG. 1). In this state,
As shown by the arrow in d of FIG. 1, the lid body 2 is moved with respect to the case body 1. Then, as shown in FIG. 1e, the side wall 2a of the lid body 2 engages with the side wall 1a of the case body 1. Then, as indicated by the arrow in e of FIG.
The case body 1 is moved upward. Then, as shown by f in FIG. 1, the lid body 2 can be automatically covered on the case body 1.

As described above, in covering the case body 1 with the lid body 2, in the present invention, the lid body 2 is not moved with respect to the case body 1, but is formed into a regular shape as shown by b in FIG. By moving the case body 1 which is relatively difficult to deform in a state where the lid body 2 which is relatively difficult to keep is stationary, the case body 1 is covered with the lid body 2 as a result.

In this case, the lid body 2 and the case body 1 are moved while holding the two side walls 2b, 2b of the lid body 2 which are continuous with the side wall 2a and are orthogonal to the side wall 2a. The two side walls 2b, 2b do not bend inward.

In particular, the two side walls 2b, 2b of the lid body 2
When the two side walls 2b, 2b are held by arranging the holding plates 4a, 4a so as to contact the inner surfaces of the two side walls 2b, 2b, the two side walls 2b, 2b are not bent inward by the both holding plates 4a, 4a. Not both holding plates 4
Since a and 4a can be located between the side walls 1b and 1b of the case body 1 and the side walls 2b and 2b of the lid body 2,
The two side walls 2b, 2b of the lid body 2 can be reliably positioned outside the two side walls 1b, 1b of the case body 1. Then, from this state, the pair of left and right holding plates 4a,
When 4a is moved to the position farthest from the side wall 2a along the two side walls 2b, 2b, the movement causes the two side walls 2b, 2b of the lid body 2 to move to the side of the case body 1.
The side walls 2a while being positioned outside the two side walls 1b, 1b
Can be further engaged with the side wall 1a of the case body 1. After that, when the case body 1 is moved upward,
It is possible to cover the case body 1 with the lid body 2 automatically and surely.
