DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for removing a refill container, and more particularly, to a method for packing and selling refill products such as an inner plate for refilling cosmetics. The present invention relates to a method and an apparatus for taking out a refill container when separating and taking out one sheet.

[0002]

2. Description of the Related Art When the contents of a compact container or the like are exhausted, only the inner plate in the compact container needs to be replaced, and only the inner plate is sold. When the middle plate is sold, the middle plate is stored in advance in a refill container and sold in order to protect the contents filled in the middle plate and to improve the characteristics of the product.

As shown in FIG. 5, a refill container 1 is formed by integrally forming an upper lid 2a via a hinge portion 2c on a container body 2b having a storage portion 2 for storing a medium filled with cosmetics and the like. It is made of a synthetic resin product having a thickness of about 1 mm.

[0004] The operation of filling a refill container with a medium dish is performed in the following procedure. That is, when the inner plate is accommodated in the accommodating portion 2, the inner plate is bent at the hinge portion as shown by an arrow in FIG. 5, and the ridge portion of the container body 2 b is fitted into the concave portion of the upper lid 2 a.
The flange 3 of the container body 2a is inserted into the cut 4a formed in the flange 4 of the container body 2b.

[0005] Since the refill container 1 is formed as a molded product, it is formed as shown in FIG.
b and the upper lid 2a are delivered from a container manufacturer in a state of being overlapped.

As described above, since the refill containers are delivered in a stacked state, they must be separated one by one prior to the filling process of the inner plates. However, this separation operation has conventionally been performed manually in the middle of an automatic line. It is done in.

[0007]

When the refill containers are stacked, the tapered concave and convex portions of the adjacent containers bite into each other, and require considerable force without peeling by hand. Are extremely difficult and work efficiency is poor.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an easy and efficient means for separating and taking out one refill container from a refill container group constituted by stacking the refill containers.

The suction means can be constituted as container suction jigs having different suction cup positions, and these jigs can be exchanged for the apparatus and have a reference portion at the time of exchange. It can be configured to do so.

Incidentally, the container suction jig has an end supporting portion of the refill container, and the reference portion can be constituted by a dovetail for engaging in a dovetail groove.

[0017]

The containers other than the refill container to be taken out are held down, and the refill container to be taken out is pulled out in the stacking direction of the refill containers while being sucked by the suction means.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, reference numeral 5 denotes a container set magazine as a storage means for accommodating refill containers in a stacked state, and a large number of refill containers 1 are placed on the container set magazine in a stacked state. ing. As shown in FIG. 2, the container set magazine 5 is inclined such that the left side, which is the container take-out side, is lower.

The degree of the inclination is such that it slides down on the container set magazine 5 by its own weight of the refill container group,
The refill container is brought into contact with the suction means. At the left end of the container set magazine 5, a container suction jig 6 as suction means for a refill container is located. As shown in detail in FIG. 3 (a), the container suction jig 6 is provided with two suction cups 7 using suction force due to a difference in air pressure in two rows. Reference numeral 9 denotes an air passage communicating with the suction cup, and the other end communicates with the vacuum means.

As shown in FIGS. 3 (a) and 3 (b), the container suction jig 6 is provided with a support 6a for supporting the flange 3 of the refill container.
And a support portion 6b for supporting the flange portion 4, and a lower support guide 8, 8 for correcting the level at the time of taking out the container is provided at an intermediate position across one row of the suction cups 7.
have.

As shown by a broken line in FIG. 3B, the refill container 1 is sucked by the suction cup 7 of the container suction jig. And the container body 2b
The suction cups 7 are adsorbed by a total of four suction cups 7.

A protrusion 10 is formed on the bottom of the container suction jig 6 as a reference when the jig is replaced, and is engageable with a dovetail groove formed on a pedestal 11 which is a part of the moving means. The pedestal 11 guides a guide 18 on a base 14 configured as a part of a posture control means for controlling the posture of the container suction jig 6.
And is slidable. The pedestal 11 is connected to the piston of the vertical cylinder CY1 provided on the base 14, and is slid on the base 14 with the operation of the vertical cylinder.

One end of the base 14 has a pin 1
The other end is pivotally connected to the tip of a piston of an erecting cylinder CY2 as a posture control means by a pin 15. The base end side of the erecting cylinder CY2 is pivotally connected to a member (not shown) integral with the advancement member 12.

The advancing member 12 is guided by a guide (not shown) and is movable leftward in FIG. 2, and the advancing cylinder CY3 is used for the movement.

In FIG. 1, in a direction orthogonal to the container stacking direction in the refill container group on the container set magazine 5, both sides of the container set magazine extend toward the center of the container set magazine and can be retracted. The pressing members 16 and 17 are provided.

These holding members 16 and 17 are provided with holding cylinders CY4 and CY provided on a stationary member (not shown).
5 is attached to each piston.

(2). Description of Operation In FIGS. 1 and 2, when the pistons of the holding cylinders CY4 and CY5 move forward, the falling of the refill container group is held by the holding members 16 and 17.

Next, as the piston of the erecting cylinder CY2 advances, the surface of the container suction jig 6 and the surface of the refill container set in the container setting magazine 5 become parallel (see FIG. 7).

Next, when the pistons of the holding cylinders CY4 and CY5 return, the refill container group on the container set magazine 5 is lowered, and at the same time, the piston of the vertical cylinder CY1 is advanced. Simultaneously with the forward movement of the up-and-down cylinder CY1, the pistons of the holding cylinders CY4 and CY5 retreat, and the holding members 16 and 17 escape, so that the containers in the magazine slide down. When the vertical cylinder has advanced most, the refill container hits the suction cup 7, is positioned, and is sucked by the air suction force (see FIGS. 4 and 8).

Here, the reason why the natural fall utilizing the sliding of the refill container and the advance of the piston of the vertical cylinder CY1 are performed simultaneously is to ensure that the container hits the suction cup more reliably. .

The refill container 1 is supported at four locations by a suction cup 7, and the flanges 3, 4 are supported by supports 6a, 6b. Under this condition, press cylinder CY

0).

Next, as shown in FIG.
Since the piston 1 returns, the container suction jig 6 moves together with the pedestal 11 in a direction away from the container set magazine 5, and
Only the second refill container is pulled apart.

At this time, as shown in FIG.
If the refill containers are tightly stacked, even if one refill is taken out, the next container will be pulled out together,
It is easy to be in the state of a letter, and there is a risk of causing the next supply failure. At this point, since the lower support guide 8 is protruded, the lower support guide 8 pushes the lower support guide 8 to correct the level even if it is in a "U" shape, so that the container is in a flat state as shown in FIG. It is sucked. In the state of FIG. 8 in which the jig 6 is advanced most, the holding members 16 and 17 are retracted, and the container is in a free state. Maintain the layered state as shown in FIG.

Next, when the piston of the erection cylinder CY2 returns, the base 14 rotates counterclockwise in FIG. 2 around the pin 13 as shown in FIG. The container is in an upright state (the state shown in FIG. 5).

Next, as shown in FIG.
The piston 3 moves forward, and the first refill container together with the advance member 12 is located immediately below the transfer cylinder CY6 having the suction cup 7.

When the transfer cylinder CY6 is operated, the suction cup 7 is lowered to suck the first refill container, and the suction of the suction cup 7 on the container suction jig 6 is stopped.

Next, the piston of the transfer cylinder CY6 is returned, and the first refill container is moved laterally together with the transfer cylinder CY6 by another appropriate moving means, and moved to an arbitrary middle plate setting position. Then, the setting of the inner plate is performed.

The erecting cylinder CY2 and the advancing cylinder CY3 return to the original state, and the above-mentioned steps are repeated again, whereby the refill containers on the container set magazine 5 are sequentially separated one by one, and It will be moved to the pan mounting position.

As described above, by the combination of the suction means and the holding means, the refill container is automatically and surely and efficiently separated and taken out. In addition, even if the shape of the refill container is various, it is possible to cope with it by making the jig dedicated to the container easy in advance. Therefore, a common reference portion is formed in each container suction jig. The reference portion is a ridge that engages with a dovetail groove formed on the base 11.

[0040]

According to the present invention, when one refill container is separated from the refill container group constituted by stacking the refill containers, the operation can be performed easily and efficiently.
