Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applied to automatic packaging of can products such as dry cell batteries, canned beer, canned youth, etc., in which the printed product design is aligned in a certain direction in a pre-packaging process. Regarding the alignment method.

[Conventional technology]

Can products such as dry batteries, canned beer, canned youth, etc.
Multiple pieces may be shrink wrapped. The surfaces of can products are printed with various designs, and in the case of shrink packaging, it has conventionally been impossible to match the surface designs of a plurality of can products.

[Problem that the invention seeks to solve]

However, when multiple can products are shrink-wrapped and displayed on a product display shelf, the display effect is poor because the positions of each can product are not aligned, and in extreme cases, the front design of the can product is There is a problem in that it may not appear on the surface at all.

To solve this problem, either print the front design of the product on a separate piece of paper in advance and package it so that the front design of the product is always visible, or print the front design of the product on the Shrink film itself. is possible, but it is not preferable as it increases the packaging cost. Therefore, the most desirable thing is to align the orientation of the products when shrink-wrapping the products so that the print on the front side of the product always faces the front in the packaged state.

In response to this demand, the present invention aims to provide a new method for automatically aligning the positions of a plurality of can products in a pre-packaging process.

[Means for Solving the Problems] The present invention includes a drive roller, and a pressure roller that pinches and separates a can product from the drive roller by moving toward and away from the drive roller, A fiber sensor seam detection means detects the seam of the rotating can products, and simultaneously feeds the plurality of can products to a plurality of positioning mechanisms for positioning the can products, and the plurality of can products are fed into the positioning mechanism. A method for manufacturing a packaged can product, which comprises aligning the can products in a certain direction, and then simultaneously sending the plurality of can products to a packaging mechanism and packaging each can product with each can product oriented in a desired direction. Each of the rollers includes a drive roller and a pressure roller that clamps the can product between the drive roller and moves away from the drive roller, and is rotated by the fiber sensor seam detection means. Equipped with multiple positioning mechanisms that detect the joints of canned products and position the canned products.
Can product packaging body manufacturing, characterized in that it has a feeding mechanism that simultaneously feeds a plurality of can products to the positioning mechanism, and a feeding mechanism that simultaneously feeds the plurality of can products aligned by the positioning mechanism to the packaging mechanism. It consists of a device.

〔Example〕

A specific example of implementing the method of the present invention is shown in the drawings and will be explained according to this example.

The drawing shows an embodiment in which eight dry batteries are aligned at the same time, and A1 to A8 in the drawing indicate the respective positioning mechanisms.

Each positioning mechanism includes a drive roller 3 that is rotationally driven via a gear system 2 by the driving force of a drive motor 1, a free rotation roller 4 adjacent to this drive roller 3, and a drive roller 3 and a free rotation roller. 4, and has a pressing roller 5 which operates toward and away from the driving roller 3 in order to clamp and release the dry battery C between the driving roller 3 and the driving roller 3.

The compression rollers 5 constituting each positioning mechanism are attached to one operating rod 6 so that they operate simultaneously, and the clamping force of the dry battery C is automatically adjusted by the elastic force of the spring 7. It's like this.

At the positions of these positioning mechanisms, a shutter support plate 8 for placing the dry cell battery C between the rollers is provided, and is movable into and out of the position between the rollers.

This positioning mechanism is also provided with a fiber sensor seam detection means 9, which detects the shadow of the seam of the dry battery C, and activates the drive motor 1.
The operation of the dry batteries C is stopped, and the rotation of the dry batteries C by the drive roller 3 is stopped so that the positions of the dry batteries C are oriented in the same direction.

In the figure, reference numeral 10 denotes a chuck mechanism, which simultaneously clamps a plurality of dry batteries C that are sent in irregular directions. In this raised state, the battery C is moved laterally to just above the positioning mechanism A, and further lowered to release the clamping action and feed the dry battery C to each positioning mechanism A.

Next, numeral 12 in the figure is a feeding mechanism positioned directly below the positioning mechanism A.

In the embodiment of the method of the present invention as described above,
First, a plurality of dry batteries C are sent into the clamp position 11 with their orientations being irregular. These dry batteries C are simultaneously clamped by the lowering and clamping action of the chuck mechanism 10. Next, the chuck mechanism 10, while holding the plurality of dry batteries C, rises as shown by the upward arrow in FIG.
Thereafter, the chuck mechanism 10 descends, releases the clamping action, and sends each dry battery to the positioning mechanism A. After completing this feeding action, the chuck mechanism returns to its original state and waits just above the clamp position 11 for the next dry battery clamping.

Each of the fed dry batteries C is placed between rollers 3, 4 and 5.
It is placed on the shutter support plate 8, which was located between the shutter support plate 8 and the shutter support plate 8, which was waiting to protrude. Next, the actuating rod 6 operates in the direction of compressing the dry batteries, and compresses the plurality of dry batteries C between the drive rollers 3 using the respective pressing rollers 5.
As a result, the dry batteries C rotate by receiving the rotational force of the drive roller 3, respectively. Then, the sensor of the fiber sensor seam detection means 9 detects the seam of each dry battery, stops the drive motor, and aligns the positions of each dry battery.

After that, the shutter support plate 8 is retracted, and the dry batteries are sent out in the aligned direction.

〔Effect of the invention〕

As mentioned above, in the method of the present invention, a plurality of canned products are simultaneously fed into a plurality of positioning mechanisms, and the plurality of canned products are sent out at the same time with their orientation aligned, so this alignment work can be carried out immediately before shrink packaging. This method has the great advantage of being able to package a plurality of canned products with all orientations aligned.
