JPS5885144A - Inspection of labels - Google Patents

Abstract

PURPOSE:To make it possible to inspect certainly defective labels and make it certain that no defective product is ovelooked by feeding intermittently a rolled sheet on which labels are pasted on and performing visual inspection of labels when they are stopped. CONSTITUTION:A motor 6 that rotates a winding shaft 5 is driven intermittently by a control circuit and so on. Every time a sheet B that is directed to a bobbin 4 is run for a certain distance, it stops for an appropriate time, and during this stopping a label A is visually inspected. The rolled sheet B is mounted on a shaft 3, and the end of the drawn sheet is fixed on the cylinder core 4 that is mounted on the winding shaft 5 with the end running along the guide shafts 7 and 8. When a start switch 11 is turned on in this state, the rotation and stopping are repeated according to a beforehand setup time schedule, and the defective product removal inspection can be made for sure by stopping labels and no defective object is overlooked.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inspection method for detecting defective products from printed labels attached to rolled sheets.

Labels, labels, and stickers attached to various products,
(hereinafter simply referred to as a label) is printed and cut into a predetermined shape, then attached to a band-shaped backing sheet and rolled.
It is automatically peeled off from the sheet during the process of pasting it onto the product.
It is attached to the product with an adhesive surface.

By the way, after printing, labels often produce defective products, such as those with faded ink or damaged paper. It is necessary to avoid this at all costs, as it can lower your reputation and damage your image.

For this reason, the labels after printing are visually inspected to ensure that defective products are removed to prevent the above-mentioned problems from occurring.

In conventional visual inspection of labels, a rolled sheet is continuously run and an inspector constantly watches the moving label while inspecting it.

However, inspection work that requires constantly looking at continuously moving labels causes great fatigue for workers, and because they are continuously moving, accurate inspection is difficult, and many defective products are left uninspected. There was a rush.

In this way, when inspecting labels, it is more important to improve accuracy than to improve efficiency.

This invention was made in view of the above points, and provides an inspection method that allows visual inspection of labels to be performed with high accuracy without overlooking defective products, and that can reduce worker fatigue. The purpose is to provide.

The structure of the present invention is such that the rolled sheet with labels attached thereto is fed intermittently, and the visual inspection of the labels is performed in a stopped state.

Hereinafter, the present invention will be explained based on specific examples shown in the accompanying drawings.

Fig. 1 shows an example of an inspection device, which includes a shaft 3 for setting a rolled sheet B with labels A pasted at regular intervals on a top plate 2 of a frame 1, and a cylinder core for winding the sheet B. 4 is provided, and a motor 6 for driving the winding shaft 5 is attached to the lower part of the top plate 2.

The rolled sheet B attached to the shaft 3 is pulled out to the front side of the frame 1, guided to the cylinder core 4 along the guide shafts 7 and J/8 attached to both sides of the top plate 2, and is guided to the front side of the frame 1. At this time, the seat B travels in a straight line between the guide shafts 7 and 8.

The label A attached to the sheet B faces the outer surface of the sheet B, that is, the front surface of the frame 1 between the guide shafts 7 and 8, so that the label A can be visually observed from the front side of the frame 1.

The motor 6 that rotates the winding shaft 5 is driven intermittently by a control circuit or the like, and the sheet B heading toward the winding core 4 stops for an appropriate time every time it travels a predetermined distance. 1. A visual inspection is performed.

Intermittent mileage of seat I3 1. The length is set to be equal to or shorter than the straight-line running portion between both gates 7 and 8, so that all labels A must be stopped at the straight-line running portion so that visual inspection can be performed without fail.

The above intermittent travel distance and travel speed are 0 in frame 1.
1) It can be controlled freely by operating the provided knobs 9 and 10, and it can also be rotated continuously at high speed to rewind the sheet B.

This invention has a configuration as shown in L. In order to visually inspect the rolled label A after printing, the rolled sheet B is attached to the shaft 3, and the tip of the drawn sheet B is moved to the guide shaft -I/ It is fixed to the cylinder core 4 attached to the winding shaft 5 while aligning it with l/7.8.

If the start switch 11 is turned on in this state to start the inspection, the motor 6 will repeatedly rotate and stop according to a preset time as shown in the time chart shown in FIG. Therefore, the sheet B to which the label A is attached moves intermittently to the cylinder core 4 side, and the inspector must move the guide 17 during the stop time when the sheet B stops running.
．． Visually inspect label A between 8 and 8.

In this way, since the stationary Pel A is inspected, each label can be inspected reliably and at the same time the strain on the eyes can be reduced. Furthermore, when the sheet B is moved again after it has stopped for a certain period of time, the inspector only needs to look away from the sheet.

As described above, according to the present invention, the sorting with labels affixed to them is carried out intermittently and the visual inspection of the labels is performed in a stopped state, so that the defective product removal inspection of the labels By stopping the inspection, inspection can be carried out reliably, no defective products will be overlooked, and inspection accuracy will be greatly improved.

In addition, since it is only necessary to visually check the stopped labels, the strain on the eyes is reduced, and fatigue can be reduced even during long hours of work.
