Abstract

PURPOSE:To make it possible to stick a label on a joint of packing paper even if the paper is thin by applying magnetic ink to the end of piled packaging paper, packaging an article in such a manner that the end comes to a joint, and detecting the end by means of a magnetic sensor. CONSTITUTION:Magnetic ink 4 containing metal powders such as iron powders is applied by means of a coating roller 6 to an end 2a of a plurality of packing papers 2 which are piled up. In this case, since a plurality of sheets of paper 2 are paled up, the ink 4 is not applied to a principal side of the paper 2 and hence value of the paper 2 is not reduced by the ink 4. An article 8 is packaged with said paper 2, in which the article 8 is packaged in such a manner that the end 2a of the paper 2 to which the ink 4 has been applied comes to a joint 3. By inspecting the end 2a by means of a magnetic sensor, the joint 3 of the packing paper can be detected. Consequently, even when the packing paper is thin, its joint 3 can be detected, A label 30 is applied to the joint 3 which has been detected.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for attaching a label, and more particularly to a method for attaching a label to a seam portion of wrapping paper used to package an article.

(Prior art) In this type of conventional label pasting method, as the size of the item changes, the position of the seam of the wrapping paper that wraps it also changes. One method was to detect it with a switch and attach a label to the seam.

(Problem B that the invention seeks to solve) However, with this conventional label pasting method, if the wrapping paper is thin, for example, it is not possible to detect the seam of the wrapping paper using a photo sensor or a contact switch. In some cases, it was not possible to attach a label to the seam of the wrapping paper.

Therefore, the main object of the present invention is to provide a method for attaching a label, which allows a label to be attached to the seam portion of wrapping paper even when the wrapping paper is thin.

(Means for Solving the Problems) The present invention includes a step of stacking a plurality of wrapping papers, a step of applying magnetic ink to the ends of the stacked wrapping papers, and a step of stacking a plurality of wrapping papers, and a step of applying magnetic ink to the ends of the wrapping papers coated with the magnetic ink. There is a process of wrapping an article with wrapping paper so that it forms an eye, a process of detecting the seam of the wrapping paper by detecting the edge of the wrapping paper coated with magnetic ink with a magnetic sensor, and a process of detecting the seam of the wrapping paper by using a magnetic sensor to detect the edge of the wrapping paper coated with magnetic ink. This method includes the step of supplying the label to the seam of wrapped wrapping paper.

(Function) In the step of applying magnetic ink, since a plurality of wrapping papers are stacked on top of each other, magnetic ink is applied only to the ends of the wrapping paper and not to its main surface. Therefore, the value of the wrapping paper is not lost.

Furthermore, in the wrapping process, the article is wrapped in wrapping paper so that the edges of the wrapping paper coated with magnetic ink form a seam.

In the detecting step, a seam of the wrapping paper is detected by using a magnetic sensor to detect the edge of the wrapping paper coated with magnetic ink. Therefore, even if the wrapping paper is thin, the seams of the wrapping paper can be detected.

In the step of supplying the label, the label is supplied to the detected seam portion of the wrapping paper.

Therefore, the label is attached to the seam of the wrapping paper.

(Effects of the Invention) According to the present invention, even if the wrapping paper is thin, a label can be attached to the seam portion of the wrapping paper.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Example) In this example, first, as shown in FIG. 1, a plurality of wrapping papers 2 are stacked.

Then, magnetic ink 4 containing metal powder such as iron powder is applied to the end portions 2a of the plurality of stacked wrapping papers 2 using, for example, an application roller 6. In this case, since a plurality of wrapping papers 2 are piled up, the magnetic ink 4 is not applied to the main surface of the wrapping paper 2.

Therefore, the value of the wrapping paper 2 is not impaired by the magnetic ink 4.

Then, as shown in FIG.
is packaged. In this case, the article 8 is wrapped with the wrapping paper 2 so that the end 2a of the wrapping paper 2 coated with the magnetic ink 4 forms the seam 3.

Then, the article 8 wrapped in the wrapping paper 2 is, for example,
A label is pasted to the seam 3 portion of the wrapping paper 2 using the label pasting device 10 shown in FIG. A and FIG. 3B.

That is, this labeling device 1o includes a conveyor 12 for conveying the articles 8. This conveyor 12 has two rotating shafts 14a and 14b provided at an interval.
Two belts 16a and 16b are hung on these rotating shafts 14a and 14b at intervals.

A magnetic sensor 18 is provided between the two belts 16a and 16b of this conveyor 12.

This magnetic sensor 18 is for detecting the seam 3 of the wrapping paper 2 at the bottom of the article 8 conveyed by the conveyor 12, and when it detects the magnetic ink 4 at the end 2a of the wrapping paper 2. It outputs a detection signal to the

This magnetic sensor 18 is connected to an input end of a control unit 20 that includes, for example, a timer. When a predetermined time set by a timer has elapsed since the detection signal was input to the input terminal of the control unit 20, the control unit 20 controls the label supply device 22 (to be described later).
It is configured to output a drive signal for driving from its output end.

The label supply device 22 includes a holding reel 24 provided below the conveyor 12, and a continuous label body 26 is held in the form of a roll on the holding reel 24. This label continuous body 26 is made up of a large number of labels 30 temporarily attached at intervals to one main surface of a strip-shaped release mount 28.

Furthermore, this label supplying device 22 has two parts of the container 12.
includes a peeling plate 32 provided between two belts 16a and 16b. This peeling plate 32 is for sharply folding back the peeling mount 28 of the continuous label body 26, peeling off the label 30 from the peeling mount 28, and feeding the label 30 upward.

Further, a take-up reel 34 is provided below the conveyor 12. This take-up reel 34 is attached to the peeling plate 3
This is for winding up the peelable mount 28 that has been sharply folded back at step 2. Therefore, this take-up reel 34 has
A motor 36 is connected.

The motor 36 of the take-up reel 34 is connected to the output end of the control section 20 described above. Therefore, this label supply device 22 uses a drive signal that is output from the output end of the control unit 20 after a predetermined time has elapsed since the magnetic sensor 18 detects the magnetic ink 4 on the edge 2a of the wrapping paper 2 of the article 8. Drive with.

In addition, the predetermined time in this case can be determined by adjusting the timer of the control unit 20 so that the article 8 can be moved from the magnetic sensor 18 part to the peeling plate 32 of the label supplying device 22 by adjusting the timer of the control unit 20.
The time is set to be the same as the time it takes to be transported to the site. Therefore, this label supply device 22 has its peeling plate 3
It is driven when the seam 3 of the wrapping paper 2 of the article 8 is located at the two parts.

Therefore, with this label sticking device 10, the label 30 can be stuck to the seam 3 of the wrapping paper 2 of the article 8, as shown in the bottom view in FIG. In this case, since the seam 3 of the wrapping paper 2 of the article 8 is detected by the magnetic sensor 18, the seam 3 is detected even if the wrapping paper 2 is thin.

Therefore, even if the wrapping paper 2 is thin, the label 30 can be attached to the seam 3 portion.
