Abstract

(57) [Summary] [PROBLEMS] To prevent bending of a soft sample to be conveyed. SOLUTION: When a soft sample is held and conveyed to a predetermined position of a material testing machine, the soft sample is bent and held by a bending holding means so that the soft sample does not bend to a predetermined position of the material testing machine. Transport.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft sample transfer device for automatically transferring a soft sample to a grip of a material testing machine.

[0002]

2. Description of the Related Art In a material testing machine, particularly a so-called automatic machine for continuously testing a large number of samples, a transport device is automatically operated to transport a sample from a storage container to the material testing machine. ing.

[0003] Particularly, in a device for transporting a soft sample such as a film, the air pad is operated, the soft sample is sucked, held and transported to a predetermined position, and then gripped by a gripper of a material testing machine.

[0004]

However, as shown in FIG. 5, in the case of a soft sample, since the tip end side is cantilevered from the suction portion by the air pad, the film is bent by its own weight.

[0005] When such bending occurs, the soft sample may be bent or bent when mounted on a gripper of a material testing machine.
In addition, it was not possible to insert between the gripping teeth of the gripping tool, and in such a case, the operation of the automatic machine had to be stopped and the test had to be repeated.

An object of the present invention is to solve such a problem and appropriately mount a soft sample transported to a material testing machine to a gripper of the material testing machine.

[0007]

According to the present invention, when a soft sample is conveyed to a predetermined position of a material testing machine, the soft sample is bent and held by a bending holding means, and a bending due to its own weight occurs. It is characterized in that it is conveyed to a predetermined position of the material testing machine so as not to do so.

[0008] Specifically, for example, the bending holding means is constituted by combining the bending means with the sample holding means, and it is only necessary to attach the bending means to the conventional apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIG.
This will be described with reference to FIGS. FIG. 1 is a diagram showing a schematic configuration of a soft sample transport device according to an embodiment of the present invention. Reference numeral 1 denotes a vacuum pad for adsorbing and suspending the sample TP placed in the storage container, a pad 1a made of silicone rubber is provided at one end, and an air suction device (not shown) is provided at the other end. Provided. A pair of the vacuum pads 1 is attached to the first plate 3 so as to be vertically slidable between a first screw 1b and a second screw 1c, and the vacuum pad 1 is attached to the vacuum plate 1 in a downward direction. A biasing first spring 4 is provided. The first plate 3
The second plate 6 is attached to the movable member 8 of the elevating cylinder 7 via the connecting rod 5.

On the other hand, as shown in FIG. 2, the sample TP sucked into the pad 1a is applied to the vacuum pad 1.
Bending guide 2 for bending in the short side direction around a
1 is attached. The curved guide 21 is attached to each of the pair of vacuum pads. By making the curved guide 21 detachable from the vacuum pad 1, it is possible to handle samples other than the soft sample.

Next, the operation of the soft sample transport device of FIG. 1 will be described with reference to FIG. Next, of the plurality of samples TP stored in the storage container 2, the evacuation cylinder 7 is operated to lower the vacuum pad 1 so as to suck the sample TP placed on the uppermost portion to be transported. After lowering the vacuum pad 1 to a position where the pad 1a contacts the surface of the sample, the suction device is operated to transfer the sample TP to the pad 1
a. Since the vacuum pad 1 can slide against the first plate 3 between the first screw 1b and the second screw 1c against the first spring 4, the thickness of the vacuum pad 1 varies within a certain range. Can correspond to the sample TP.

In this manner, when the sample TP is sucked into the pad 1a, at the same time, the sample T is
P curves in the short side direction. Then, while the sample TP bent by the bending guide 21 is sucked into the pad 1a, the lifting cylinder 7 is operated to suspend the sample TP.

After the vacuum pad 1 on which the sample TP is suspended is lifted to a predetermined position, the lifting cylinder 7 is moved by a moving mechanism (not shown) as shown in FIG. After rotating by degrees,
After moving horizontally, the sample TP is loaded between the gripping teeth 31a, 32a of the upper and lower gripping tools 31, 32 of the material testing machine. As described above, even after the elevating cylinder 7 and the like are rotated by 90 degrees, the rigidity of the sample TP is increased by the curvature, so that the sample TP does not bend due to its own weight. And gripper 3
After gripping the sample TP at 1, 32, a predetermined material test is performed.

In this embodiment, the vacuum pad 1
The curved holding means is constituted by attaching a curved guide 21 to the curved surface, but as a modified embodiment, as shown in FIG.
Alternatively, the soft sample may be gripped by moving the pair of gripping teeth so as to abut each other. in this case,
In order to be able to insert the grip teeth on the lower surface side of the sample with the grip teeth,
The space is provided between the lower surface of the sample and the table on which the sample is arranged.

In this case, by making the bending holding means replaceable, a sample other than a soft sample can be used while being replaced with a normal sample holding means.

[0016]

As described above, according to the present invention, when the sample is mounted on the material testing machine, the sample is bent in the short side direction, so that the sample does not bend or bend by its own weight. The sample can be appropriately mounted on a material testing machine.
