Abstract

PROBLEM TO BE SOLVED: To permit the continuous measurement of compressibility without cutting a test piece by permitting the measurement of compressibility while moving the object to be measured between an unwinding roll and a take-up roll. SOLUTION: A contiguous compression measuring device is provided with an unwinding roll 2 in which a long object to be measured 1 is wound up, a take-up roll 3 to take up the unwound object to be measured 1, a load exerting device part 62 which is provided between the unwinding roll 2 and the take-up roll 3 and exerts a predetermined load on the object to be measured 1, and a deformation measuring part 7 for measuring the amount f deformation at a deformed part on which a load is exerted by the load exerting device part 62. As this permits the measurement of compressibility while moving the object to be measured 1 between the unwinding roll 2 and the take-up roll 3, it is advantageously possible to measure compressibility continuously without cutting a test piece.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous compression measuring machine, and more particularly to an apparatus for continuously measuring the compressibility of a long printing blanket or a composite cloth.

[0002]

2. Description of the Related Art Conventionally, when measuring the compressibility of a flexible product or a semi-finished product such as a printing blanket as described above, a constant load is applied to an object to be measured.
This is done by measuring the amount of deformation. Since the measurement of the compressibility of the DUT is performed by sampling inspection to assure the quality of the product or semi-finished product, the test piece must be formed by cutting the length of the DUT to be measured. Generally, this test piece is applied to a compression measuring machine.

However, in the above-described method for producing a test piece, since the test piece is cut and formed, at least the vicinity thereof cannot be used as a product, and it takes time to manufacture the test piece. There is a disadvantage that the test cannot be performed efficiently.

The present invention has been made in view of the above points, and has as its object to provide an apparatus for continuously measuring the compressibility of a long object as described above.

[0005]

Means for Solving the Problems To solve the above problems, a continuous compression measuring machine according to the present invention comprises: an unwinding roll on which a long object to be measured is wound; A take-up roll that takes up the object to be measured, a load application device unit provided between the unwind roll and the take-up roll to apply a predetermined load to the object to be measured, and a load applied by the load application unit. And a deformation measuring unit for measuring a deformation amount of a portion deformed by the above-described method.

According to the present invention, the compressibility can be measured while moving the object to be measured between the unwinding roll and the winding roll, so that the compressibility can be continuously measured without cutting off the test piece. This has the advantage of being possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of a continuous compression measuring machine of the present invention, and FIG. 2 is a perspective view.
The continuous compression measuring machine has an unwinding roll 2 in which a long measuring object 1 is wound from one end and a winding roll 3 which is wound from the other end of the measuring object 1. The DUT 1 is guided by guide rolls 4 and 5, and is wound up from the unwinding roll 2 (upstream side) in the direction of the winding roll 4 (downstream side).

The continuous compression measuring machine has a load applying unit 6 for applying a load to the object 1 between the guide rolls 4 and 5. The load application unit 6 includes a pedestal 61 for supporting the bottom surface of the object to be measured when a load is applied, and a load application unit 62 for applying a load from above.

Then, on the downstream side of the load applying unit 6,
A deformation measuring unit 7 for measuring the thickness of the object is provided. By measuring the thickness in this manner, it is possible to know the amount of deformation of the DUT 1. The deformation measuring unit 7 may be a device that measures a thickness by, for example, a change in eddy current.

In this embodiment, the load applying portion 62
Is movable in the width direction (X direction). Pedestal 61
Is provided on the bottom surface of the DUT 1 over the entire width of the DUT 1, so that it can be moved in the X-direction in this manner, so that the entire width of the DUT 1 (in the X-direction) Can be measured anywhere.

According to the continuous compression measuring machine of the present invention, the DUT 1 unwound from the unwinding roll 2 is passed through the guide rolls 4 and 5 and partially wound around the winding roll 3. As described above, the load applying device 6 and the deformation measuring unit 7 are provided downstream of the guide rolls 4 and 5. After setting the DUT 1 in this way, the take-up roll 3 and the unwind roll 2 are driven to drive the DUT 1
Is moved (in the Y direction). By moving in this manner, a load can be applied to a desired portion of the DUT 1 in the Y direction by the load application unit 6, and the amount of deformation can be measured by the deformation measuring unit 7. That is, the compressibility of any part in the Y direction can be measured.

Further, in order to measure the compressibility of a desired portion in the width direction of the DUT 1, the load applying portion 62 is moved in the X direction, and a load is applied to the desired portion for measurement. This makes it possible to measure the compressibility at any point in the X direction.

According to the continuous compression measuring machine according to the above-described embodiment, even if the measuring point is any place of the object to be measured, it can be easily moved by moving the object 1 and by moving the load portion. In addition, there is an advantage that measurement can be performed continuously.

[0014]

As described above, according to the continuous compression measuring device of the present invention, the compressibility can be measured while moving the object to be measured between the unwinding roll and the winding roll. This has the advantage that compressibility can be measured continuously without cutting off
