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 packaging shampoo liquid containers, cosmetic liquid containers, beverage liquid containers and the like.

[0002]

2. Description of the Related Art In a shampoo solution filling line or the like, after filling a bottle container 1 aligned in a direction with an inner solution,
As shown in (A), the containers 1 are gripped in parallel by each of the plurality of chucks 2 and simultaneously inserted into the box 3.

[0003]

However, in the prior art, in the process of inserting the container 1 gripped by the chuck 2 into the box 3, variations in the container gripping posture by the chuck 2,
Alternatively, due to inertial shaking of the container 1 gripped by the chuck 2, the insertion tip 1A of the container located outside of the plurality of containers spreads outward from the outer edge of the box opening, and as a result, the insertion tip of the container 1 An insertion error may occur in which the portion 1A is caught by the outer edge of the box opening.

It is also conceivable to dispose a container guide 4 on the chuck 2 for centering the posture of the container 1 gripped by the chuck 2 on the chuck shaft (FIG. 6).
(See (B)). However, the container guide 4 merely serves to center the posture of the container 1 on the chuck shaft, and can completely suppress the above-described expansion due to the inertial shaking of the container 1 held by the chuck 2. Therefore, it is difficult to secure a smooth packing operation without insertion error.

An object of the present invention is to prevent an insertion error in which the insertion tip end portion of a container is caught in the box opening edge portion and ensure a smooth boxing work.

[0006]

According to a first aspect of the present invention, there is provided a method of packing a container in which a plurality of containers are gripped in parallel by a chuck and are inserted into a box at the same time. The posture of the container located outside of the container is slanted so that the insertion tip of the container is directed inward in the process of inserting the container.

According to a second aspect of the present invention, in a container packing apparatus for holding a plurality of containers in parallel by a chuck and inserting them in a box at the same time, the container is positioned outside the plurality of containers held by the chuck. The container attitude control unit is provided to tilt the container attitude so that the insertion tip of the container is directed inward when the container is inserted into the box.

According to a third aspect of the present invention, in addition to the second aspect of the present invention, the container attitude control section is disposed on the chuck and is located outside in cooperation with the container holding operation by the chuck. The container is configured by an elastic member that abuts against the side portion of the container and elastically presses the side portion inward.

[0009]

[Operation] In the process of inserting the container gripped by the chuck into the box, the posture of the container (the container that may be caught on the opening edge of the box) of the plurality of containers is determined by the insertion tip portion. It is tilted so that it points inward.
Therefore, not only is the expansion of the insertion tip portion caused by shaking or the like based on the inertia of the container completely suppressed, but also the insertion tip portion is positively squeezed and inserted inside the box from the edge of the box opening. Therefore, it is possible to prevent an insertion error in which the insertion tip portion of the container is caught in the box opening edge portion and ensure a smooth box packing operation.

The attitude control section for inclining the insertion tip of the container so as to be directed inward is constituted by the elastic member provided on the chuck, whereby the attitude control section is arranged and controlled. Can be simplified, and the device configuration can be extremely simplified.

The container boxing device 10 is arranged in a subsequent process of a shampoo liquid filling line, for example, a container supply aligning machine, a container direction aligning machine, a filling machine, a cap sealing machine and a serial number printing machine. Then, the container boxing device 10 fills the content liquid and then seals the cap, and arranges the bottle containers 11 of 2 rows and 6 columns (12 in total) arranged in parallel in the same direction on the front surface of the container. In the arranged state, they are inserted into the box 12 all at once.

That is, the container boxing device 10 has a total of 12 chucks 14 suspended and supported by a chuck head 13 that circulates along a boxing path in a 2 × 6 matrix, and is mounted on a conveyor. Each of the twelve containers 11 held by the container carrier (hakama) 15 conveyed in two rows and six columns is gripped by each chuck 14, and the containers 11 are put into the boxing path. It is to be collectively inserted into the box 12.

However, as shown in FIG. 5, each chuck 14 is provided with a pair of open / close pawls 22, 22 below the cylinder 21 supported by the chuck head 13, and is provided at the tip of the piston rod of the cylinder 21. The opening and closing cam 23 opens and closes so that the cap portion 11A of the container 11 can be held.

At this time, among the chucks 14, the chucks 14 located on both outer sides in each row have elastic members 24 as a container attitude control section fixed to their outer surfaces. The elastic member 24 is composed of a leaf spring, and is provided at its lower end with an R-shaped container abutting portion 25 forming a ridge toward the inside.

As a result, the chuck head 13 descends from the ascending side, and the cap portion 11A of the container 11 held in each container carrier 15 is grasped by each chuck 14 in the container gripping step. The elastic member 24 of the chuck 14 elastically abuts the container abutting portion 25 of the corresponding outer container 11 from the shoulder portion to the side portion. At this time, since the container 11 is held by the container carrier 15 and is immovable, the elastic member 24 elastically bends and deforms outward, and elastically presses the side portion of the container 11 toward the inside.

Then, the chuck head 13 rises from the lower end, and the containers 11 grasped by the chucks 14 are extracted from the container transporting tools 15 in the container removing step.
1 is no longer held by the container carrier 15, and the elastic members 24 of the chucks 14 on both outer sides try to elastically restore from the elastic bending deformation state to the initial state. As a result, of the containers 11 gripped by the chucks 14, the outer container 11 with which the container abutting portion 25 of the elastic member 24 abuts, the box 12A due to the elastic restoring force of the container elastic member 24. The insertion tip portion 11B (bottom portion) is posture-controlled in an inclined shape (inclination angle α) so as to be directed inward, and can be inserted into the box 12 in this posture control state.

Hereinafter, the container 11 by the container boxing device 10
The box packing procedure will be described. (1) In the standby step, the chuck head 13 is set to the rising end, and the chucks 14 in the form of 2 rows and 6 columns of the chuck head 13 are arranged in the same manner in the 2 rows and 6 columns of container transport tools on the transport conveyor. Correspondingly arranged on each container 11 in 15 (see FIG. 1 (A)).

(2) In the container holding process, the chuck head 13
Is lowered from the rising end, and each chuck 14 moves the above (1)
The cap portion 11A of the corresponding container 11 is grasped.
Interlocking with the container gripping operation by the chuck 14, the container abutting portions 25 of the elastic members 24 provided on the outer chucks 14 elastically abut from the corresponding shoulder portion to the side portion of the container 11, The elastic member 24 is elastically bent and deformed outward by the container carrier 15 with respect to the stationary container 11 (FIG. 1).
(B), see FIG. 2).

(3) The chuck head 1 is used in the container removing process.
3 rises from the descending end, and the containers 11 gripped by the chucks 14 are pulled out from the container transport tools 15. As a result, among the containers 11 gripped by the chucks 14, the outer container 11 with which the container abutting portion 25 of the elastic member 24 is abutted has the elastic bending deformation state of the elastic member 24 described above. As the elastic member 24 is restored to the initial state, the elastic restoring force of the elastic member 24 controls the posture of the insertion tip 11B into the box 12 in an inclining manner (see FIG. 1C and FIG. 3). ).

(4) The chuck head 13 is used in the container collecting process.
Collects the chucks 14 by moving them in the parallel direction. At the same time, the unsealed box 12 is placed below the chuck head 13 (see FIG. 1D).

(5) In the container inserting process, the chuck head 13
Descends from the ascending end and inserts the container 11 held by each chuck 14 into the box 12 (see FIG. 1 (E) and FIG. 4).
Each chuck 14 is released when the insertion tip portion 11B (bottom portion) of each container 11 is intruded into the box from the opening edge 12A of the box 12 by a certain amount, and each container 11 is released.
Drop into 2 and insert. At this time, of the containers 11 gripped by the chucks 14, the outer container 11
With the posture control according to the above (3), the insertion tip portions 11B are inserted so as to be narrowed toward the inside of the box from the opening edge portion 12A of the box 12.

(6) The chuck head 13 returns to the standby step (1) (see FIG. 1F).

The operation of this embodiment will be described below. In the process of inserting the container 11 gripped by the chuck 14 into the box 12, the posture of the container 11 (the container that may be caught in the box opening edge 12A) out of the plurality of containers 11 is inserted. The tip portion 11B is tilted so as to be directed inward. Therefore, not only is the expansion of the insertion tip portion 11B caused by shaking or the like due to the inertia of the container 11 completely suppressed, but also the insertion tip portion 11B is positively recessed from the box opening edge portion 12A toward the inside of the box. Becomes Therefore, it is possible to prevent an insertion error in which the insertion tip portion 11B of the container 11 is caught by the box opening edge portion 12A, and to ensure a smooth box packing operation.

The chuck 1 is provided with a posture control section for inclining the insertion tip portion 11B of the container 11 so as to be directed inward.
By using the elastic member 24 arranged in No. 4, the arrangement and the control operation of the posture control unit are simplified,
The device configuration can be extremely simplified.

In the practice of the present invention, the container attitude control section may comprise tilting means for tilting the chuck itself in the attitude control direction of the container.

Further, the container attitude control section may be provided separately from the chuck and independently provided on the side of the container in the process of inserting the box so that the attitude control action can be given to the container. .

Further, the container attitude control section is not limited to a resilient member such as a leaf spring, but is provided with a container pressing actuator or the like so that the container attitude control force output from the actuator or the like can impart an attitude control action to the container. May be
