Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a label form to which two or more types of labels are attached.

<Prior art> In recent years, the way in which label forms are used has become more complex, and label forms used for process control, quality control, etc. contain the necessary information as well as various labels made of different materials and sizes suitable for the purpose. It has become necessary to wear clothes.

<Problem to be solved by the invention> As described above, when different types of labels are attached to the same backing paper, if the bonding process is uniform for each type, the peeling performance will differ depending on the type. , resulting in a difference in the required peeling force. Specifically, for example, compared to high-quality paper labels, synthetic paper labels generally have a stronger adhesive force and are therefore more difficult to peel off, and even if they are made of the same material, the larger the paper, the wider the adhesive surface, so the adhesive strength is stronger. The peeling performance differs depending on the type.

In some cases, when printing on a label form, there may be problems such as the label separating on the printer, or the bonding force being too strong, causing peeling and damage to the backing paper. Ru.

An object of the present invention is to provide a label form that can be separated with substantially the same peeling force even if the labels are of different types such as material and size.

<Means for Solving the Problems> The present invention provides for a form with two or more types of labels attached, only on the label joining surface of the mount, according to the peelability based on the size and material of the labels. , a silicon layer is formed by setting the relative thickness so that the layer thickness is small for those that are easy to peel, and thick for those that are difficult to peel, and a glue layer of the same material is formed on the back side of the silicon layer. It is characterized by having a labeled label affixed to it.

<Function> The label is bonded to the mount via the adhesive layer on its back side and the silicone layer formed on the label bonding surface of the mount. The silicon layer can then be peeled off.

Therefore, by changing the thickness of the silicon layer within a certain value, the peeling performance will vary. That is, if the silicon layer is made thicker, the affinity between the glue layer and the mount will be lowered, making it easier to peel off, and if it is made thinner, the affinity will be increased, making it harder to peel off.

To explain this in more detail, as shown in FIG. When formed, silicon is embedded within the rough surface r. The exposed surface of the silicon layer x from the rough surface r becomes an effective area that exhibits the peeling ability.

For example, as shown in FIG.
The affinity between the label l and the mount p is inhibited, and the label l cannot be adhered to the mount p side. Furthermore, if the thickness of the silicon layer x is small as shown in FIG. Mount p
It will be glued to. That is, by changing the layer thickness of the silicon layer x that can cover the entire surface of the paper (layer thickness t in Figure 1A) or less, the affinity between the adhesive layer y and the mount p can be improved. This can be adjusted. Therefore, by setting the thickness of the silicon layer x, a desired peelability can be imparted to the label l.

Therefore, when attaching a large paper and a small paper to the same mount p, the larger paper is more difficult to peel off, so the amount of silicone applied to the bonding surface is larger than that of the small paper. and increase the layer thickness. As a result, the peeling force remains constant even if the size of the paper differs. In addition, synthetic paper is generally more difficult to peel than wood-free paper, so in the case of synthetic paper, the amount of silicon applied to the bonding surface is greater than that of wood-free paper to reduce the layer thickness. Make it large.

By adjusting the layer thickness, labels can be separated with substantially the same peeling force even if the labels are different in size, material, etc.

<Example> An embodiment of the invention will be described with reference to FIG.

Reference numeral 1 is a label form for continuous printing used for process control, etc., and feed holes 2 are continuously formed on both edges thereof. On the mount 3 of the label form 1 are rectangular labels 4 of different types.
a, 4b, and 4c are attached.

Here, the label 4a is made of weather-resistant synthetic paper, and is used, for example, when it is attached to the outer surface of a product to be transported outside, such as a vehicle. Also label 4
The label b is made of high-quality paper having the same shape as the label 4a, and is used, for example, when it is attached to the interior of a vehicle. Furthermore, the label 4c is made of high-quality paper and is smaller than the label 4b, and is used for key management by being attached to a vehicle key, for example.

Then, these labels 4a, 4b, 4c are attached to a predetermined bonding surface f on the mount 3. That is,
As shown in FIG. 3, a predetermined amount of silicon layer x is formed in advance on the bonding surface f, and the silicon layer x
Each label 4a, 4b, 4c is bonded and placed on the top with an adhesive layer y formed on the back surface thereof.

Incidentally, the application of the silicon layer x and the setting of its layer thickness can be achieved by a normal printing method.

That is, for the labels 4a to 4c, the silicon layer x on the joint surface f of the synthetic paper label 4a has the maximum thickness, the high quality paper label 4b of the same shape as the label 4a has the next layer thickness, and the small high quality paper label The silicon layer x of 4c has the minimum thickness.

Label form 1 coated with such a silicon layer x
are further fed, and the labels 4a to 4c having adhesive layers formed on their lower surfaces are respectively bonded onto the silicon layer x.

Another way to adjust the thickness of the silicon layer x is to adjust the roughness of the mesh formed on the coating member.
Various proposals may be made, such as setting it corresponding to a predetermined silicon layer x.

As a premise for controlling the layer thickness of the silicon layer x, it is necessary to be able to detect the layer thickness, and such detection can be performed using, for example, a known coating amount measuring means using fluorescence x-ray analysis.

By detecting such layer thickness, it becomes possible to generate differences in layer thickness corresponding to various labels.

<Effects of the Invention> The present invention sets the layer thickness of the silicon layer x to enable peeling of labels of different sizes, materials, etc. on a label form in accordance with the types,
Since the label can be separated with the same peeling force, it is possible to attach the label to the label form with the optimal bonding force regardless of the type of label, making it easy to peel and preventing damage to the label form due to peeling. It has excellent effects such as:
