Description

[Detailed Description of Device] a. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for measuring the adhesive force of adhesive labels, adhesive tape, and other adhesive paper.

B. Conventional technology It is easy to measure the adhesive strength of adhesive labels, adhesive tapes, and other adhesive papers by the peeling method. Peeling methods include 90 degree peeling and 180 degree peeling. The adhesive strength of adhesive paper is greatly affected not only by the characteristics of the adhesive but also by the rigidity of the base coated with the adhesive, so to measure the adhesive strength of the adhesive, a peel test is performed by changing the peel angle. There is a need. Peel force is measured
Usually, a sample adhesive sheet is adhered to a fixed reference surface,
The required peeling force is measured at a peeling angle of 90 degrees or 90 degrees, but there are few devices that can measure 90 degree peeling and 180 degree peeling with one device, and the conventional device as shown in Fig. 6 is used. Was used to measure the peeling adhesive strength at a peel angle of 180 degrees or 90 degrees. As shown in Fig. 6A, when peeling 180 degrees,
The adherend S with the surface as a reference plane is fixed vertically, the sample tape T is folded back 180 degrees, and the folded tip is pulled vertically upward to measure the tensile strength by the load cell 25. As shown in FIG. 6B, an adapter such as a linear way 21 that can move freely in only one horizontal direction is used on the measuring stand of the same tester, and the adapter to which the sample is attached is held, and the adapter is attached. In order to move the sample tape T in the horizontal direction in synchronism with the vertical movement, the extension arm 24, the wire 23, the pulley 22 and the like are attached to the tester, and the sample tape T tip is pulled in the vertical direction at the same time. The pulling force of the sample tape T is measured by the load cell 25 so that the adherend S is pulled and moved in the horizontal direction so that the sample tape T is constantly pulled in the vertical direction.

C. Problems to be solved by the invention With the above-mentioned device, when trying to measure both 180-degree peeling and 90-degree peeling at approximately the same time, the adapter or extension arm must be exchanged for 180-degree peeling and 90-degree peeling. . However, replacement of adapters etc. takes time,
There was a problem that workability was poor. Also, since it takes time to replace the adapter, there is a difference in the time elapsed from the time when the sample tape is attached to the adherend until the measurement is made between the 180-degree peeling and 90-degree peeling measurements. There is also a problem that it becomes difficult to compare measurement data.

An object of the present invention is to solve the above-mentioned problems and to provide an adhesive force measuring device capable of easily measuring the peeling adhesive force for 180 degree peeling and 90 degree peeling.

D. Means for Solving Problems A device for measuring peeling force includes a sample winding roll, a drive motor for the sample winding roll, a traveling roller driven at the same peripheral speed as the sample winding roll, and a sample of the sample winding roll. A measuring head that includes a sensor that detects a required winding force, and that can travel linearly by the traveling rollers, a base, a traveling track plate that is held above the base in parallel with the base surface, and on the base and Comprised of a measuring stand equipped with an adherend holding means for sample attachment, which is provided between the base and the running track plate perpendicularly to the surface of the running track and the running track plate, and runs on the running track plate of the above measuring stand The measurement head can be placed as much as possible, and the traveling roller of the measurement head is floated from the mounting surface, or the rotation of the traveling roller of the measurement head is stopped so that only the winding roll can be rotated. The above measurement It can be placed on the base of the stand or on the running track plate.

E. Action When peeling the sample tape at an angle of 90 degrees, the peeling point retreats with respect to the adherend on which the sample is attached, so the winding position is the same as the movement of the peeling point. It is necessary to move in parallel, and when peeling the sample tape at an angle of 180 degrees, the peeling point only retreats in the pulling direction on the substrate on which the sample is attached, so the peeling point is relative to the pulling direction. Does not move, so the winding position can be fixed.

The device of the present invention has the ability of the measuring head to run at the same speed as the winding speed, and the installation location can be changed.
When it is placed on the running track plate and is self-propelled, 90-degree peeling measurement can be performed on the sample tape attached on the base parallel to the base surface, and the sample tape is held on the base parallel to the base surface. Then, if the traveling roller is installed by floating it on the base of the measuring head, the measuring head does not move and only the tape is wound, so 180 degree peeling measurement can be performed, or the measuring roller can be placed on the traveling track plate. 180 degree peeling measurement is possible even if the sample tape is attached to the adherend held on the base while floating.

In the above description, the traveling roller is floated above the traveling surface so that the traveling roller idles so that the measurement head does not move even if the sample winding roll rotates. It is also possible to turn on and off the clutch by interposing a clutch mechanism between them, and to wind the sample without moving the measuring head.

In the measuring head H, 1 is a take-up roll for winding the sample tape T, 2 is a drive motor, 3 is a measuring head incorporating the take-up roll 1, the drive motor 2 and the like. It is a pair of running rollers. Reference numeral 4 is an auxiliary roller which stabilizes the measuring head while traveling on the traveling track plate 5, like the traveling roller 3. A timing belt 6 connects the driving pulley 11, the traveling pulley 13 and the winding pulley 12 so that the driving force of the driving motor 2 is applied to the traveling roller 3 and the winding roll 1 so that the peripheral speed of both rolls is Communicate to be the same. A torque detector 7 detects the winding roll driving torque between the winding roll 1 and the winding pulley 12 by the rotation of the drive motor 3. Reference numeral B is a support rod provided in the lower rear part of the measurement head in parallel with the winding roll 1 and with the lower surface higher than the lower surface of the winding roll 1.

S is an adherend, and the sample tape T is adhered thereon. The adherend S is a standard Japanese Industrial Standard (JI
SZ0237), but in the case of on-site comparative measurement, any object plane may be used.

ST is a measurement stand. At the measuring stand ST, D
Is used to fix the adherend S on the surface of the base by means of a presser foot 8. The traveling track plate 5 is held above the base D by a support C so as to be parallel to the base surface, and there is an open groove parallel to the paper surface of the drawing at the center of the width in the vertical direction on the paper surface of the drawing. The lead tape R can be hung from the measuring head.

E and E ′ are adherend holding plates, which are fixed on the side of the measurement stand, perpendicular to the surface D of the base, and on the columns of the measurement stand.

A is a measuring stand with the measuring head fixed.

The measurement head is held on the base with the running roller 3 and the auxiliary roller floating above the base D by providing a contact surface that does not move against the base.

The usage and operation of the above-mentioned apparatus will be described. Place the measuring stand on a suitable substrate surface. The upper surface of the base D of the measurement stand is horizontal. When measuring 180 degree peeling, the measuring head positioning base A is fixed to the right end of the base D as shown by the chain line in FIG. 1 and as shown in FIG. As shown in FIG. 3, the traveling head 3 is mounted on the measuring head positioning table and the traveling roller 3 is a base table
Install it so that it floats from above. Returning to FIG. 2, sample tape T
Is adhered to the adherend S, the adherend S is fixed on the base D by the adherend presser 8, the one end of the sample tape T is held by the lead tape R, and the slack portion of the lead tape R is fixed. Take-up roll 1
And the drive motor 2 is driven at a set speed. Since the traveling roller 3 is installed so as to idle by the measuring head positioning base A, the sample tape T is wound by the winding roll without moving the measuring head. A torque detector 7 detects the torque when the sample tape T is wound on the winding roll 1.

When performing 90 degree peeling, as shown in FIG. 1, the measurement head is arranged on the running track plate 5 so as to be self-propelled, the sample tape T is set in the same manner as the above example, and the slack of the lead tape R is set. This portion is wound on the winding roll 1, the traveling roller 3 and the auxiliary roller 4 are positioned on the traveling track plate 5 so that the peeling angle becomes 90 degrees, and the drive motor 2 is driven at the set speed. The take-up roll 1 is driven by the drive motor 2.
The lead tape R is wound on the sheet, the traveling roller 3 is rotated, and the adhesive force measuring device moves on the traveling track plate 5 at the same speed as the sample winding speed. Therefore, the positional relationship between the peeling point of the sample tape T and the take-up roll 1 is constant, and the sample tape T is kept at the peeling angle of 90 degrees.
To be wound up. During the peeling period, the torque detector 7 detects the tension required for peeling. In any of the above cases, the detection signal is stored and calculated by a computer (not shown), and the measurement result is displayed by a display device (not shown). Also, 18
As shown in FIG. 4, by fixing the adherend S to the adherend holding plate E or E ′, the adherend S is perpendicular to the running track plate 5 as a measuring method of the 0 ° peeling. It is also possible to carry out the measurement by fixing the measuring head H on the running track plate 5 and holding it by the measuring head positioning base A.

In the above description, 180-degree peeling and 90-degree peeling are performed separately, but for the same tape on the same adhered surface, 180

Is dropped on the adhesive surface and is pressed onto the sample tape with a constant load, and after a predetermined time, the drive motor 2 is driven at a set speed. Since the traveling roller 3 is installed so as to idle by the measuring head positioning base A, the adherend S ′ is lifted by the winding roll without moving the measuring head. The torque detector 7 detects the maximum torque when the adherend S ′ is lifted up by the winding roll 1 and separated from the sample tape. As described above, the present invention can be applied to the tack characteristic test.

Also, when performing 90 degree peeling measurement or 180 degree peeling measurement, if the rotation angle of the winding roll 1 is detected, the winding length can be detected. If the start and end positions are set, the motor 2 can be automatically stopped / reversely rotated at the measurement end position, and the lead tape R can be automatically returned to the start point. By doing so, it is possible to further improve the measurement efficiency.

In the above-described embodiment, when the measuring head is not moved such as 180 degree peeling and tack test, the measuring head is fixed by using the measuring head positioning base A. However, a clutch is interposed between the traveling roller and the motor to wind the winding head. It is also possible to eliminate the positioning base A by rotating only the take-up roll so as not to move the measuring head.

G. Effect According to the present invention, switching between 180 degree peeling and 90 degree peeling can be performed simply by changing the placement location and placement of the measuring head. Even when used for 90 degree peeling measurement and the rest for 90 degree peeling measurement, the measurement can be performed with almost no loss time, and the measurement error due to the difference in elapsed time after application is eliminated, and the measurement accuracy is further improved. Also, 180 degree peeling and 90
In addition to measuring the degree of peeling, it is possible to perform tack property tests,
The range of applications has expanded.
