Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the circumferential alignment of a bottle having a cylindrical shape or a similar shape, continuously conveyed in a horizontal orientation, and subjected to packaging printing at a predetermined position of the bottle. A method and an apparatus thereof.

[0002]

2. Description of the Related Art Conventionally, a bottle having a cylindrical shape or a similar shape is conveyed sideways, and when the bottle is aligned in the circumferential direction, it is manually performed or a sensor is used (for example, , JP-A-4-173616).

[0003]

The conventional manual alignment method has the drawback of poor accuracy and inefficiency, and when a sensor is used, a bottle is marked and a reciprocating rotary device is used. Must be provided separately,
There was a problem that it became a very large-scale device.

An object of the present invention is to enable accurate, high-efficiency alignment of a cylindrical bottle or a bottle of a similar shape in the circumferential direction without using a large-scale device.

[0005]

PROBLEM TO BE SOLVED: To provide a hook provided on a chain used for transporting a bottle with a protrusion capable of conforming to a concave portion of the bottle having a fixed relationship with bottle printing, and a bottle rotating device in the transporting process. Is provided.

[0006]

According to the present invention, a bottle rotating device is used to fit a concave portion of a bottle, which has a constant relationship with the phase of bottle printing, to a protrusion of a hook provided on a chain. It becomes possible to easily carry out the alignment in the circumferential direction of the bottle while continuously transporting in the shape of a bottle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the device of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a schematic front view showing a bottle 1.
Is, for example, a plastic container in which a cleaning agent is enclosed in a bottle. In recent years, characters, pictures, etc. have been directly printed on such plastic containers.
In order to print the packaging film and the like without covering the printing surface of the bottle 1, it is necessary to accurately align the bottle 1 in the circumferential direction.

By the way, in the printing of a round bottle, in order to print while rotating the bottle, one concave portion 13 (FIG. 5) is provided in order to make the printing phase constant. This is a method used also for avoiding the parting line of the mold, which is formed at the time of molding the resin bottle, from the printing surface of the bottle.

Therefore, it is usual that the phase between the recess and the bottle printing has a certain regularity. However, although there are some inexpensive ones that perform arbitrary printing phases without providing recesses, printing with recesses is generally used in high-grade bottles, such as the present invention, which tries to match the phases up to the packaging film. Is. The present invention makes it possible to align the bottles in the circumferential direction by utilizing this regularity. The bottle 1 is transported in the direction of arrow A by a transport conveyor 2 composed of a chain 5, a guide bar 3 and a hook 4, and is rotated by a rotary roller 11 and a free roller 12.
It is conveyed to the next step 15 via the bottle rotating device 6 composed of (FIG. 3).

FIG. 2 is a right side view of the conveyor 2. The conveyor 2 conveys the bottle 1 sideways, and is provided with two guide bars 3 and 3 and a hook 4, and the hook 4 is provided at predetermined intervals on a chain 5 that is stretched endlessly. The bottle 1 is provided and protrudes in the middle of the guide bars 3 and 3 and abuts on the rear end portion of the bottle 1 placed on the bars 3 and 3 in a sideways manner and conveys the bottle 1. The chain 5 is appropriately continuously driven by a drive device (not shown). The two guide bars 3 and 3 place the bottle 1 on its side so that the bottle 1 can slide on the bars 3 and 3.

The hook 4 is provided on the chain 5 and is provided with guides 8 and 8 arranged on the table surface 7, as well as the metal fitting 1.
0 is guided by the guides 9 and 9 arranged on the table surface 7, and comes into contact with the rear end portion of the bottle 1
To transport. Although the chain 5 is used in this embodiment, the present invention is not limited to this, and a belt may be used, for example.

FIG. 3 is a plan view of the bottle rotating device 6.
The bottle rotating device 6 is connected from the two guide bars 3 and 3, and is composed of a rotating roller 11 and a free roller 12 which are appropriately operated by a driving means (not shown).
In this embodiment, two free rollers are used for one rotating roller, but the number of free rollers is not limited to this. Further, in the present embodiment, the rotary roller 11 is provided at the lower part of the transport bottle 1, but it may be provided at the upper part. Anything that rotates the transport bottle 1 in the circumferential direction is sufficient.
Reference numeral 4 is a hook. FIG. 4 is a front view of the bottle rotating device 6. Reference numeral 14 is a protrusion provided on the hook 4.

FIG. 5 is a right side view of the bottle rotating device 6. The driving roller 11 and the free roller 12 are the bottle 1
The hook 1 is a device for rotating, and the projection 1 for fitting with the recess 13 of the bottle 1 is provided at the contact portion of the hook 4 with the bottle 1.
4 are provided.

Next, a method of aligning the bottle in the circumferential direction according to this embodiment having the above-mentioned structure will be described with reference to FIGS. 1 and 5. In FIG. 1, when the bottle 1 is fed on the conveyor 2 in a sideways manner, the hook 4 comes into contact with the rear end portion of the bottle 1 and successively conveys the bottle 1 in the direction of arrow A. When the bottle 1 reaches the bottle rotating device 6,
In FIG. 5, the rotating roller 11 driven by a driving unit (not shown) rotates in the direction of arrow B to rotate the bottle 1 in the direction of arrow C, and the projection 14 provided on the hook 4 is rotated.
And the concave portion 13 of the bottle 1 are fitted, the circumferential alignment of the bottle 1 is completed, and the bottle 1 is sent to the next step 15 (film packaging or the like).

[0015]

As described above in detail, in the bottle circumferential alignment method and apparatus according to the present invention, the bottle circumferential direction can be accurately measured with high efficiency without using a large-scale device. This has the effect that alignment can be performed easily. This makes it possible to easily perform packaging film printing, etc. without disturbing the contents of bottle printing in the next process, and to use it as a new method in the information transmitted to consumers. .
