DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box packing device for accommodating bottles in a box inside a paper box such as a cardboard box or other material.

[0002]

2. Description of the Related Art Conventionally, when a product bottle is packed in a cardboard box or the like in a factory or the like, a cardboard box that has been boxed (a cardboard box molded into a rectangular tube and having one opening closed). The bottles are inserted in an assembled state from an unclosed opening, and then the opening is closed by closing means such as hot melt. In this case, insertion of the bottle into the cardboard box is performed by moving the chuck mechanism up and down while chucking the necks of the assembled bottles with the chuck mechanism.

[0003]

When the neck of a bottle is chucked as in the prior art, the structure of the chuck mechanism is complicated, so that the box packing device is also increased in size and complexity. In addition, there is a concern that the bottle may fall off due to a shock or the like acting on the inside of the chuck.

Accordingly, an object of the present invention is to provide an apparatus capable of packing a bottle with a simple structure while reliably preventing the bottle from falling off.

[0005]

In order to achieve the above object, a bottle packing apparatus according to the present invention comprises a bottle supply mechanism for supplying a plurality of bottles in an aligned state to a standby position, and a plurality of sleeves in an assembled state. A sleeve assembly arranged in parallel,
The sleeve assembly and the bottle supplied to the standby position by the bottle supply mechanism are relatively slid in the sleeve axial direction to insert the bottle into each sleeve, and then the sleeve assembly is moved together with the bottle in the sleeve radial direction. It has a transfer mechanism for transferring each bottle into the box waiting at the insertion work position, and a support means for supporting the bottom of the bottle during the movement of the bottle from the standby position to the insertion work position.

In the above case, at least two adjacent surfaces of the box are not closed, and one of the unclosed surfaces is used as an insertion port of the bottle held by the sleeve assembly into the box.
The other unclosed surface may be an outlet for the sleeve assembly extracted from the bottle out of the box. As the two adjacent non-closed surfaces, the upper surface 4a of the box (see FIG. 1) and one end surface 4b1 in the direction orthogonal to the transport direction of the box transport mechanism are considered.

In addition, a plurality of flaps for closing the unclosed surface serving as an insertion port are provided, and the bottom flap is pushed out to the open side by a guide member, and the bottle is held by the sleeve assembly. Should be transported into the box.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic structure of a bottle packing apparatus according to the present invention. As shown in the drawing, the box packing device includes a bottle supply mechanism 2 for aligning and supplying a plurality of bottles 1, a sleeve assembly 3 in which a plurality of sleeves 3a are arranged in parallel in a collective state, and a cardboard box or the like. The main components are a box transport mechanism 5 for intermittently transporting the box 4 (paper box) and a transport mechanism 6 (see FIG. 2) for transporting the bottle 1 from the bottle supply mechanism 2 into the paper box 4.

[0010] The bottle 1 is supplied to the bottle supply mechanism 2 in a state of a finished product which accommodates an object to be accommodated in another process not shown and is sealed with a lid or the like. The shape (glass, plastic, etc.) and material (food, medicine, etc.) and properties (liquid, fluid, solid, etc.) of the container 1 are particularly important. It doesn't matter.

The bottle supply mechanism 2 includes a feeding means 21 for transporting the bottles in a state of being arranged in a double row (five rows in this embodiment), and a reciprocating drive source such as a cylinder which is disposed adjacent to the end of the feeding means 21.
It comprises a transfer table 23 reciprocally driven by 22 and a stopper 24 provided at the downstream end of the feeding means 21.

The feeding means 21 comprises a conveyor section 21a (see FIG. 3) composed of a belt conveyor or the like and a storage section 21b provided at a downstream end thereof. The storage section 21b is formed of a plate-like member, the upstream end of the upper surface of which is continuous with the conveying surface of the conveyor section 21a, and the downstream side thereof is slightly inclined downward. The bottle 1 that has reached the downstream end of the conveyor section 21a is transferred to the storage section 21b, is slid on the upper surface of the storage section 21b, and is locked by the stopper 24 protruding from the upper surface. Similarly, the subsequent bottles successively transfer to the storage portion 21b, so that the plurality of bottles 1 (here, “stage” means the number of rows of the bottles 1 in the transport direction) are kept aligned on the storage portion 21b. While being collected.

The transfer table 23 is fed by a reciprocating drive source 22
It is driven reciprocally in parallel with the feed direction of 21 and approaches and separates from the downstream end of the storage section 21b. While the transfer table 23 is away from the storage section 21b, the stopper 24 projects as described above to close the outlet of the storage section 21b, so that the bottle 1 on the storage section 21b stays. On the other hand, when the transfer table 23 approaches the storage unit 21b, the stopper 24 retreats below the upper surface of the storage unit 21b, and the bottle 1 located at the downstream end of the storage unit 21b is pushed by the subsequent bottle and transferred. Transfer to the platform 23. The transferred bottle 1 slides on the transfer table 23, stops on the positioning member 23a provided on the transfer table 23, and stops. Further, when the subsequent bottles transferred onto the transfer table 23 come into contact with the bottles, the respective bottles 1 are placed on the transfer table 23 in the above-mentioned aligned state in a collective state. Bottle 1 of specified number of stages
Is placed, the reciprocating drive source 22 is restarted and the transfer table 23
Is retreated, and the transfer table 23 is transferred to a predetermined standby position A (shown by a solid line in FIG. 3).

In FIGS. 1 and 3, two bottles 1
Exemplifies a case in which the bottles are transferred onto the transfer table 23, but the number of bottles 1 to be transferred is arbitrary, and one or three or more bottles can be transferred. The number of steps to be transferred at one time
It can be changed by adjusting the dimension of the transfer table 23 in the width direction (the feeding direction of the feeding means 21), and can also be changed by adjusting the opening / closing timing of the stopper 24, for example.

Each sleeve 3a of the sleeve assembly 3 is mounted on the lower surface of a base 31 (see FIG. 2) with its axial direction directed upward and downward. Each sleeve 3a is formed of a resin material or the like into a cylindrical shape, for example, a cylindrical shape, and has an inner diameter that is large enough to allow the bottle 1 to be inserted. In this case, the entire length of the bottle 1 does not necessarily need to be insertable into the sleeve 3a, and the lower portion 1a of the bottle 1 may not be insertable as shown in FIGS. Thus, there is a large diameter portion 1a at the bottom of the bottle 1,
When the other portion of the bottle 1 is inserted into the sleeve 3a, the sleeves 3a can be attached to the base 31 in close contact with each other, and the sleeve assembly 3 can be further compacted.

The box transport mechanism 5 is composed of a belt conveyor or the like. The box transport mechanism 5 sequentially feeds each of the paper boxes 4 to a position B (insertion operation position) where a bottle insertion operation is performed while holding the paper boxes 4 in an unsealed state (a state in which they are not completely sealed). . The paper box 4 is mounted on the transport surface with at least two adjacent surfaces, for example, the upper surface 4a and one end surface 4b1 (in this embodiment, both end surfaces 4b1 and 4b2) facing the bottle supply mechanism 2 not closed. Is pressed between a pair of fixing members 51 having an L-shaped cross section, and is clamped by both fixing members 51 from both sides in the transport direction. The paper box 4 of the present embodiment includes a bottom plate 41 and both side plates 42.
In the state where only the bent portion between the bottom plate 43 and the side plate 42, the top plate 44, and the folded portion 45, which are continuous with each other, are bent at the U-shaped section, the bottom plate 41 It is pushed between the fixtures 51. The flaps 41a, 42a, 43a, and 44a are provided in the openings at both ends of the paper box 4 for each of the bottom plate 41, the side plates 42 and 43, and the top plate 44, and the respective flaps 41a to 44a are folded inward. Both ends opening is closed, both ends 4b of the paper box 4
1, 4b2 are formed.

The transfer mechanism 6 moves the sleeve assembly 3 up and down.
The slider is slid in the radial direction of the sleeve, and includes a lifting drive unit 6a and a horizontal drive unit 6b. Lifting drive 6a
Is composed of a cylinder 61 and a pair of guides 62, and the base 31 and the sleeve assembly 3
Is raised and lowered together. As shown in FIG. 2, the horizontal drive unit 6b converts the rotational output of a rotary drive source 64 such as a motor into a horizontal reciprocating motion via a link mechanism 65, and reciprocates the traveling platform 66 in the horizontal direction. The horizontal reciprocating motion of the carriage 66 is guided by a guide rail 67. The base 31 is mounted on the traveling base 66 via a connecting member (not shown), whereby the base 31 and the sleeve assembly 3 are reciprocated in the horizontal direction in conjunction with the reciprocating movement of the traveling base 66. . In the present embodiment, this horizontal movement is performed in a direction orthogonal to the transport direction of the box transport mechanism 5, so that the sleeve assembly 3 can be moved horizontally between the areas immediately above the standby position A and the insertion work position B. .

a, 42a and 44a are pressed to the open side (outside) by the flap pressers 7a and 7b. Of these, the flap retainer 7a for the bottom flap 41a is constituted by a thin plate-shaped guide member 71 arranged parallel to the side of the box transport mechanism 5. For example, the upper surface of the guide member 71 is arranged at the same level as the lower surface of the paper box 4,
Further, by making the tip of the bottom flap 41a sunk under the guide member 71 (see FIG. 2), the bottom flap 41a is restrained in a slightly opened state from a neutral position (a position parallel to the bottom surface of the box). . The lower end of the flap below the guide member 71 can be simultaneously performed when the paper box 4 is pushed between the pair of fixing tools 51, for example.

Further, a side flap 42a on the leading side in the transport direction.
And a flap holder 7b for the upper flap 44a is a thin rotating plate 72 which is configured to be swingably rotatable about a vertical axis.
It consists of. During the transportation of the paper box 4, the rotary plate 72
Is retracted to the bottle supply mechanism 2 side as shown by the two-dot chain line, and is at a position where it does not interfere with the side flaps 42a and 43a and the top flap 44a, but when the paper box 4 is transported to the insertion work position B, the solid line position in FIG. And pushes the side flap 42a and the top flap 44a on the leading side in the transport direction to a neutral posture (a posture parallel to the side surface of the box) or an opening side thereof.

In the drawing, the flap retainer 7b composed of the rotary plate 72 is provided only on the flaps 42a and 44a on the leading side in the transport direction. However, a similar flap retainer 7b is provided near the side flap 43a on the trailing side. The flap 43a may be pressed in a neutral position or an open side.
In the drawing, the flap holder 7a for the bottom flap 41a is shown.
Are provided on both sides of the paper box 4, but the flap holder 7a (the guide member 71) on the opposite side (the lower side in FIG. 3) from the bottle supply mechanism 2 side.
Can be omitted.

The transfer member 8 is disposed between the guide member 71 on the bottle supply mechanism 2 side and the transfer table 23 at the standby position A. The transfer member 8 functions as a support means for supporting the bottom of the bottle 1 during the movement of the bottle 1 from the standby position A to the insertion work position B, and the upper surface level is the upper surface of the transfer table 23 and the guide member. It is set to the same level as the upper surface of 71 (see FIG. 2). Delivery member 8, transfer table 23, and guide member
The gap between them and 71 is made as small as possible, and desirably, these upper surfaces are continuous.

Hereinafter, the operation and operation of the device of the present invention will be described.

First, the reciprocating drive source 22 of the bottle supply mechanism 2 is activated, and the transfer table 23 is moved to the feeding means 21 as shown by a two-dot chain line in FIG.
Then, the bottles 1 of a predetermined number of stages are transferred onto the transfer table 23, and the transfer table 23 is separated from the feeding means 21 and transferred to the standby position A. Next, the raising / lowering drive unit 6a of the transfer mechanism 6 is activated, and the sleeve assembly 3, which is disposed immediately above the standby position A (initial position: shown by a two-dot chain line in FIG. 1), is lowered to remove each sleeve 3a. Insert the bottle 1 into the inner periphery. Then, the horizontal drive unit 6b
Is started to move the sleeve assembly 3 horizontally, and the sleeve assembly 3 and the bottle 1 are transferred into the paper box 4 which has been waiting in the insertion work position B in advance. At this time, both end surfaces 4 of the paper box 4
Of the b1 and 4b2, the end face 4b1 on the bottle supply mechanism 2 side serves as an insertion port of the sleeve assembly 3 and the bottle 1 into the paper box 4. With the horizontal movement of the sleeve assembly 3, the bottle 1 held by each sleeve slides on the transfer member 8 and the guide member 71,
It is stored in the paper box 4. Thereafter, the lifting drive 6a is restarted, the sleeve assembly 3 is raised, and each sleeve 3a is placed in the bottle 1
Then, the horizontal drive unit 6b is restarted, and the sleeve assembly 3 is returned to the initial position (at this time, the upper surface 4a of the paper box 4 becomes an outlet of the sleeve assembly 3). The paper box 4 that has completed the above-described box packing process is transferred to a folding process (not shown), and the top plate 44 and the folded portion 45 are sequentially folded according to the procedures shown in FIGS. Etc.), and flaps at both ends
41a-44a are folded in and both ends are closed.

As described above, in the present invention, the bottle 1 is inserted into the inner peripheral portion of the sleeve assembly 3 and then the sleeve assembly 3 is slid and the bottle 1 is accommodated in the paper box 4. The structure can be simplified compared to the case of chucking a bottle,
Further, dropping of the bottle 1 due to impact after chucking or the like can be reliably avoided.

In particular, in the present invention, the bottle 1 is stored in the paper box 4 with the bottom flap 41a being pressed to the open side by the guide member 71, so that the bottle 1 is moved from the standby position A to the insertion work position B. Can be prevented from being caught on the tip of the bottom flap 41a and falling, and the stability and reliability of operation can be improved.
