Description

[Detailed Description of the Invention] [Field of application in the industry] The present invention relates to an automatic peel test piece feeding device and an automatic tensile test device, and more specifically, the present invention relates to an automatic peel test piece feeding device and an automatic tensile test device. The present invention relates to an apparatus useful for measuring the T-peel strength of adhesive surfaces such as laminated films and flexible sheet materials such as rubber.

[Conventional technology]

There are various methods for measuring the adhesive strength between two layers pasted together, but the most commonly used method is to measure the degree of adhesion of flexible and thin materials such as textile materials. is JIS
A T-peel test as shown in L-1089 etc. was conducted.
Ru. Measuring these peel strengths is very important from both process control and quality control regarding finished products.

Conventionally, this type Ill peel test has been relatively easy to handle because it is possible to prepare a V-shaped test piece in advance for the material 1i, such as metal. It is difficult to even handle flexible and thin materials such as fiber materials at a small size, for example, improvement of the gripping tool as in Japanese Utility Model Publication No. 55-17158, or tensioning as in Japanese Unexamined Patent Publication No. 55-63787, is difficult. Although only a few automated testing devices are known,
No automated equipment is known for flexible thin T-peel testing.

For this reason, -one person is required for each demarcation device.
At present, the attachment and detachment of test pieces is done manually for each test piece.

[Problem that the invention seeks to solve]

Conventionally, the T-peel test carried out at Jusakuei involves holding each test piece in a specified gripping tool (-me), measuring it with a strength testing device specializing in continuous extension type, and after the measurement. Remove the test piece 27
1- Retrieval is a complicated, monotonous and long-time work. Accidents such as getting caught were also occurring, increasing the danger.

Although not in the same field as the present invention, the above-mentioned Japanese Patent Application Laid-Open No.
Automatic tensile testing equipment for flexible materials, such as the 63737, requires work such as attaching stoppers to both ends of the specimen in advance, or placing a load on the specimen to keep it under tension. Because the method requires preparatory work that is undesirable both in terms of work and testing, it is not satisfactory as an automatic tensile test device, even though the operation is much more monotonous than in a peel test.

In manual peel testing, there is a limit to the number of test samples that can be measured.
It is impossible to determine the distance, and since known automatic tensioning devices also require a stopper, it is impossible to continuously measure hundreds to tens of sheets, or it is extremely difficult to measure. However, the drawback is that a large area is required for mounting a large test piece.

[Means for Solving Problem 76] The present invention consists of: (1) a means for moving the test piece to a fixed position by movable according to the amount of the test piece placed; , a means for controlling the operation of the mounting table and/or a transport mechanism, ① a means for transporting the test specimens in a fixed position one by one to the gripping tool of the measuring device, ③ a means for opening the test specimens into a substantially T-shape, and ■ 1. An automatic peel test piece supply device comprising a means for automatically gripping a test piece opened in a substantially T-shape; means, means for detecting the end of measurement for each sheet, means for collecting the test pieces after measurement, and detecting the total number of test pieces,
The present invention relates to an automatic tensile testing apparatus comprising means for sending a signal repeating the above-mentioned operation 1.

[Function and Examples]

In the present invention, the test piece is JLSL-10 described in +iii
As shown in 89-8-, a part of the test piece is prepared by peeling 1-7 in advance. In normal cases, it is difficult to uniformly separate parts of a test piece that have been completely glued together to form a gripping part, so the gold film may peel off in parts where adhesive has not been applied in advance, or In many cases, the gripping portion of the test piece is formed by sandwiching a suitable material such as a 11Ilt paper pattern between parts of the specimen during the adhesive treatment.

In the present invention, any method may be used to form the gripping part of the test piece, but it is possible to blow thin films or paper with low air permeability onto the bamboo between the samples, so that they remain in the gripping part. When a test piece is formed, it is advantageous because a vacuum suction type mechanism can be used as a means for transporting the test piece, which will be described later.

An embodiment of the apparatus of the present invention will be described in detail below with reference to drawing F1, but the present invention is not limited to these drawings or embodiments.

First, referring to f in the figure, the g positioning device l moves the mounting table 3 to a fixed position by means of a reversible motor 2 with a brake and appropriate transmission means. In addition to the vertically lifting type shown in this drawing and the tilted upwards and downwards type as shown in this drawing, the mounting device can also be a rotary type in which multiple mounting tables on which an appropriate number of test pieces are placed are rotated, or a testing device. Any means can be selected, such as a horizontal movement type that moves the pieces horizontally. The vertical lift type shown in the drawings is advantageous because it is easy to use the weight of the test piece and it is possible to place hundreds to dozens of thick samples in a very narrow space. It is. Father, the power source is also shown in the drawing.
In addition to the stirring type, it is also possible to use air or liquid pressure.

The test piece is kept in a fixed position by using a sensor such as the phototube 4 shown in the figure, or by inputting the test piece thickness and the number of tests t using a microcomputer. be able to.

In the mounting apparatus l shown in FIG. 1, the mounting table 3 is located at the bottom in the measurement preparation stage. When the test pieces are stacked on the mounting table 8 and preparations are completed, the operating switch is turned on to raise the uppermost test piece to a fixed position. The detection of the test piece and the operation of the transport mechanism 5, which will be described later, are connected by a suitable relay or the like, and exhibit a predetermined function. Transport mechanism 5 if necessary
When the test piece is operated and the uppermost test piece is moved, the mounting table 3 is lowered by an appropriate distance. When the mounting table 8 is lowered in conjunction with the transport mechanism 5, the second and lower test pieces from the top are lowered by their own weight, so they are not in contact with the lowest measurement test piece. Therefore, it is most advantageous because it is possible to reliably test each sheet and eliminate various resistances such as friction and entanglement during transportation.

Since lowering the mounting table 3 to the F dead center will impair work efficiency, it is sufficient to lower it to the extent that it helps ensure the above-mentioned reliable conveyance. Therefore, controlling the descent distance with a timer or with a computer increases efficiency.

Next, the carrying means 5 will be explained. The conveyance means 5 includes a pickup section 6 that holds one test piece, and a rotary or linear return movement and/or vertical movement for moving the photographed test piece to the gripping tool of the measuring device. The arm portion 7 to 0 is constructed. In the drawing, the pickup section 6 is of a vacuum suction type with scattering plates, but in addition to this,
When measuring test pieces of woven materials such as raised fabrics, it is also possible to use curved fasteners with hook-shaped or ear-shaped protrusions, or to use claw-shaped pickups. , a pick-up using an appropriate adhesive can be used for the film issue. When a vacuum suction type pickup 6 is used, if the gripping part of the test piece is made impermeable or has low air permeability, it will not only ensure that the test piece is heated up, but also prevent scattering when it is gripped by the gripping tool. This is particularly advantageous because it allows the air to flow back and allows the specimen to be quickly released from the plate.

In the drawing, the arm s7 includes a linearly actuated air cylinder 8 (hereinafter referred to as "cylinder A") and a rotary actuated air cylinder 9 (hereinafter referred to as "cylinder B").
Driven by.

For the drive, an electric method may be used other than this, and a robot arm having a pickup function may also be used. However, the use of air cylinders
As a means for transporting from a fixed position to a fixed position, it is advantageous because the transport mechanism can be constructed most quickly, reliably, and at a low cost.

The cylinders A8 and B9 are installed at optimal positions when conveying to the gripping tool of the measuring device, and at arbitrary positions where they do not come into contact with the gripping tool of the measuring device or the crosshead that moves up and down at a constant speed. In the drawing, the cylinder 8 is installed at the rear of the measuring device, and the cylinder B9 is the movable mouth of the cylinder A8.

It is installed at the tip of the TolO and the Big Our Pro is attached. First, cylinder B9 is activated to push out the threatening pickup 6, which is placed horizontally between the gripping tools of the measuring device, to a position above the mounting table. Rotate 90 degrees and pick up the scattering board 6
Stop at the fixed position. At this time, the mounting table 8 is raised, the test piece is stopped at a fixed position and brought into contact with the pickup 6, and at the same time, it is detected that the test piece is at a fixed position and a signal is sent to start conveyance. Simultaneously or several seconds after the test piece is sucked into the pickup 6, the mounting table 8 is lowered a predetermined distance, and then the cylinder B9 is reversely rotated by 90"C, and the /su/zoom 8 is returned to its original gripping position. In this way, the entire test piece can be transported accurately.

Next, we will explain how to open the test piece into a roughly T-shape.
Again, various means can be employed.

For example, by suctioning the grip part of the test piece from above and below, approximately T
It can be opened in a mold or using a small robot arm or the like. However, since the test piece to which the present invention is applied is a flexible and thin material, the above method has the drawback of being complicated and expensive. The inventors
As a result of examining various means, it was found that the use of a metal fitting 11 that opens in a substantially T-shape shown in the drawings is the simplest, most reliable, and most suitable means. In the drawings, the metal fitting 11 is an abbreviated metal fitting with a pressing part on the same plane as the tip of the pickup 6, but it does not have to be made of metal and L-shaped, and may be made of hard resin or U. Any shape can be selected as long as it is pressed against the peeling interface of the test piece and can vertically support the gripping part of the test piece.

If the metal fitting 11 according to the drawing is installed on the same side as the pickup 6, one side of the gripping part of the test specimen is folded in advance and then stacked on the mounting table, but if the metal fitting is installed on the opposite side of the pickup 6 in an unreasonable manner. There is no need to pre-fold the specimen. However, when installing the metal fittings on the opposite side of the Big Our Pro, the flexibility of the test piece often prevents it from opening in a roughly T-shape, resulting in low versatility, so the configuration shown in the drawing can be used for all test pieces. It can be said to be the best thing possible. In the drawing, the metal fitting 11 is the arm part 7 of the air cylinder B9.
Fixed.

Therefore, the metal fitting 11 always shows the same movement as the pickup 6, continues to support the adhesive interface of the test piece until the Big Our Pro sucks one side of the gripping part of the test piece, and transports it between the gripping tools of the measuring device. By maintaining the gripping part of the specimen up and down, reliable gripping is achieved regardless of the type of specimen.

Next, a description will be given of the roughly R-shaped test piece and the means for grasping it.These can be those commonly used in ordinary tensile test and measurement equipment, and do not require anything special. Therefore, it is preferable to use a commercially available gripping tool called an air holder, since the control mechanism built into the measuring device can be used as is. The air chuck 12 shown in the drawings is wired so that it is activated when the conveyance means has conveyed the test piece to the gripper. This control may be performed so that the air chuck 12 closes at the same time as the actuation light r of the cylinder A8 is applied, or a time lag of several seconds may be set using a timer for more reliable gripping. For example, as shown in JP-A-53-138779, the plate ta of the air chuck 12 is changed to the plate 1 in order to make it easier to insert the test piece.
It is also a good idea to gently curve one or both ends of the 3 to the outside.

Briefly summarizing the interactions of one embodiment of the automatic peeling test piece feeding device according to the present invention shown above, by adopting a vertically elevating movable mounting table as the mounting device, it is practically impossible to do so with the conventional method. It is now possible to easily handle flexible and thin fabrics, etc., and also to handle test specimens with large tits ranging from hundreds to tens of sheets at once. Furthermore, by utilizing the weight of the test specimen, it is possible to handle each specimen individually. It is realized that the transfer mechanism (4) can be reliably moved to the transfer machine (4).Although the transfer mechanism is a very compact configuration that combines an air cylinder and a plate-forming type pickup, the transfer mechanism of the present invention is The 7-prong transport mechanism not only has reliable transport performance, but is also very compact, quick to operate, and can be easily controlled by a series of relays, etc. with other means. Since the L-shaped metal fitting is fixed to the side of the conveyor as a means for opening it into an approximately T-shape, it is possible to reliably maintain the specimen in an approximately 'V-shape, and also prevent the shaking of the specimen during 1ti transport. It also has the effect of preventing such things, and is extremely economical.As a gripping tool for the measuring device, you can use a commercially available 20-Archuck, etc., so there is no need for a special one. Although the feeding device is extremely simple in all respects, it is extremely capable of automatically feeding flexible and flexible Alt specimens, which was previously thought to be practically impossible. This was realized in a reliable and easy-to-understand manner.

Furthermore, an automatic release paper testing device that integrates the automatic release test strip supply device (hereinafter referred to as "supply device") described in detail above will be described.

First, referring to the means for measuring T-shaped peeling over a predetermined distance, a commonly used constant-speed extension type tensile test measuring device or the like can be used. It is further advantageous if a data processing device is attached which performs calculations on the measured values thus obtained.

In the present invention, the measuring device performs constant-speed peeling over a predetermined distance from the time when the air chuck 12 closes and the pickup 6 stops suction and releases the test piece from the scattering plate due to backflow, or after a time lag of several seconds. When the measurement of the predetermined distance is completed, the signal is sent to the test piece collection device described below, and the collection device is activated. This signal can be used as it is, such as a relay built into the measuring device. When the air chuck 12 is opened and the test piece is collected, the measuring device returns to its original position.

Various methods can be used to collect the test pieces, such as blowing them away with a blower, mechanical collection, or suction. You can choose to.

In the drawings, the means by sakshi and n are used. The upper part 14 and the lower part 14; /i5 are vIA@ed by an air cylinder, are normally placed at the rear of the measuring device, and are pushed out to the position of the test piece after measurement by the measurement completion signal, When the air chuck opens, the released test piece is sucked in by the actuation of the suction cliff. The reason for using two slits on the top and bottom is to prepare for the case where the test piece is cut during peeling.
If there is no risk of the test piece being divided into two by cutting, etc.
One sakshi and n are enough.

The aspirated test piece is collected at L locations or multiple locations using a suitable transfer means such as a flexible pipe. When the suction is finished, the suction device is stopped, the upper and lower suctions are retracted to their original positions, and then a signal is sent to the measuring device to return to its original position.

The purpose of these collection means is to prevent inaccurate measurements due to test piece residue and to prevent the measurement device from operating properly, as well as to verify data and check the state of peeling. This is also necessary from a technical standpoint.

The above-mentioned supply device and measuring and collecting device are operated by individual sensors, relays, etc., as described above. Then, means for sending a signal to return mQ according to the number of test pieces will be explained.

The simplest method is to use a counter, but other methods include a method in which an appropriate sensor is used to sense the presence or absence of a test piece on the mounting table. When using a counter, the number of test pieces t must be entered in advance.
It becomes easy to check in the event of an accident such as a malfunction, and if sensors are used, the trouble of confirming and inputting the number of test pieces is unnecessary and efficient. Therefore,
If necessary, the housings can be separated, or both can be used together.

When using the automatic peel-off paper testing device according to the present invention described in detail above, the only work a person has to do is to stack the test pieces on the mounting table, and it becomes possible for one person to handle multiple testing devices.・Also, notify the completion of measurement of all test pieces,
If a means to automatically turn off the power is installed, once the test piece is placed, it can be completely unmanned, making it possible to conduct tests at night or perform other tasks during measurements. It is very useful because it allows you to go back and forth.

In addition, since the present invention has an extremely simple configuration, if the various sensors such as light sensors and weight sensors are installed in safe locations, all controls can be performed by a computer.
The usefulness can be further improved.

Although the feeding device and testing device according to the present invention are intended to measure peel strength, these devices can also be used as automatic devices for measuring tensile strength and elongation. -0 can also be used.

〔effect〕

The automatic peeling paper testing device A'a iA and self-excited peeling 1iiiIU testing device according to the present invention can handle multiple devices by one person, whereas conventional testing requires one person for one measuring device. It is intended to make complete unmanned operation practical, and to streamline the function. Although C'T is a flexible and thin material that has traditionally been widely used, it is possible to manufacture it at a very low cost because it has been automated with extremely simple construction.
It has a lot of advantages and is also economical.

Historically, in the past, it was only possible to measure the grip manually, which led to individual measurement errors. The device according to the invention has the advantages of: 1. certainty of definition, economy; It is an unprecedented device that is completely safe and highly efficient.
