Description

Detailed Description of the Invention

[0001]

The present invention relates to a test solution used in a laundry test for dyeing fastness such as fibers (soap solution, aqueous solution containing synthetic detergent, solvent such as perchlorethylene, etc.).
And the technology of weighing, counting, and automatically feeding stainless steel balls to test bottles.

[0002]

2. Description of the Related Art A washing fastness test for fibers and the like is based on JIS
(Japanese Industrial Standards) L0844 "Dyeing fastness test method for washing" and JIS L0860 "Dyeing fastness test method for dry cleaning" are specified, and one test piece (for example, 500 ml) is provided in a prescribed test bottle (for example, a capacity of 500 ml). 5 x 5 cm attached white cloth on the surface of 10 x 5 cm test piece 2
Put the pieces side by side and sew four sides roughly together, and put a prescribed amount of test solution (eg 100
ml soap solution and perchlorethylene solvent etc.) and a specified number of stainless steel balls (eg 10, 20
, 50 pieces) and sealed, and this test bottle is JIS L
0821-compliant dyeing fastness washing tester (hereinafter,
This is done by mounting it on a washing tester). Also, the above J
Since the test temperature is specified in IS L0844 and JIS L0860, the temperature of the test bottle installation tank (test tank) of the above washing tester is adjusted to the test temperature, and the test bottle is preheated before it is attached to the above washing tester. The bread was previously preheated to bring the test solution to the test temperature.

Further, the above test solution is weighed by a graduated cylinder or the like, and the stainless steel balls are counted in a test bottle by counting them one by one or by using a box into which a specified quantity is entered.

[0004]

In the above-mentioned washing fastness test, one test bottle is used to test one piece of sample. Therefore, in order to improve the efficiency of the test, a large number of test bottles ( This is often done using a washing tester that is attached (for example, 16 or 32 pieces).

For this reason, much labor is required for measuring the test solution and counting the stainless steel balls. Also, JIS L
Since the perchlorethylene used in 0860 is harmful to the human body, great care must be taken when handling it as a test solution. Further, in order to preheat the test solution to a predetermined test temperature, a preheating pan required for this is required in addition to the washing tester. A preheated pan was needed. Further, since the stainless steel balls have a small diameter of about 6.4 mm, they are easily lost during counting and at the time of loading the test bottle.

Therefore, the test solution can be maintained at the test temperature without using a preheating pan, etc., the measurement of the test solution and the counting of the stainless steel balls can be automated, and these can be safely and reliably supplied to the test bottle, resulting in labor saving. There was a strong demand for the development of a new device.

[0010]

[Function] The stainless steel ball supply mechanism stores the stainless steel balls in advance, counts them by a certain number with a steel ball counter, and supplies all the counted stainless steel balls to the test bottle at the same time. This operation is performed one or more times to supply a predetermined number of stainless steel balls to the test bottle. By performing one or more supply operations, the number of steel balls required for the test is supplied to the test bottle. It has become.
