JP2007133846A - Device for confirming and counting number of operation - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a device for confirming and counting the number of operations for preventing subjective assumption and erroneous memorization of a worker without disturbing the operation. <P>SOLUTION: A worker carries a portable radio transmission means 1 in assembly/inspection work. When a switch is operated in counting operation, counting is carried out by a separate counter 2 serving as a receiver at the same time. When the number of counting is below a predetermined number, when the number of counting is above the predetermined number, or when the number of counting reaches the predetermined number, the counter 2 serving as the receiver transmits incompletion information or completion information. By the counter 2 serving as the receiver, a work condition is checked. As provision against erroneous pressing on a count switch 6, a reset switch 7 is installed in the portable radio transmission means 1, and when the reset switch is pressed, the counting value of the counter serving as the receiver can be reduced. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a counting device for confirming the number of operations in an inspection operation and an assembly operation that require a predetermined number of times.

In a nut runner or impact wrench, a device is used that detects the number of times that a screw has been tightened when the tightening torque of the screw is reached and indicates that assembly is complete when a predetermined number of screws have been assembled.
However, in the inspection work and assembly work of the worker, in many cases, the counting of a plurality of inspection points and the counting of a plurality of assembly parts have to be relied on in contrast to the worker's memory and checklist. .

According to the above state, an erroneous inspection or work may be repeated due to a misunderstanding of the worker or a difference in memory. Although it is possible to carry a handy type counter, it is necessary to notify the production line of confirmation information when the work is completed on the production line. The trap does not have such a function.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a counting device for confirming the number of operations, which prevents an operator's belief and memory difference, and does not hinder the operations.

  In order to solve the above problems, the portable wireless transmission means for generating a count signal provided with a count switch and the count signal transmitted from the separate portable wireless transmission means are received and counted, and the predetermined number of times is obtained. A receiver / counter that emits incomplete information or completion information when it does not reach, exceeds, or reaches a predetermined number of times. Also, in case the count switch is accidentally pressed, a reset switch is provided in the portable wireless transmission means, and the count value of the receiver / counter can be reduced by pressing the reset switch.

  According to the present invention, the operator is easy to carry because the count signal transmission means is wireless, and does not hinder assembly work or inspection work. In addition, it can be confirmed whether or not the parts have been assembled or inspected at a predetermined number of times.

  One embodiment of the present invention is shown in FIG. A portable radio transmission means is provided at the time of assembly work and inspection work, and a count signal is transmitted by pressing the switch at the time of counting. The receiver / counter receives the count signal and performs counting. In some cases, the counter is decremented, and each confirmation information is issued when the predetermined number of times is reached or not reached when the work is completed. The set value can be sequentially changed by a receiver / counter body and an external input.

  In the implementation mobile of FIG. 3, the portable wireless transmitter means can store the writing instrument when marking the confirmation part on the product with the writing instrument in the inspection work, and by pressing the count switch of the transmitter means at the time of marking, the receiver / counter side Then, every time a count signal is received, the count is incremented by one.

  In the embodiment of FIG. 4, a portable wireless transmission means is attached to the work tool, a count signal is transmitted every number of operations, and a predetermined number of operations is counted. The work tool to which the portable wireless transmission means is attached is not limited to the pliers, and can be attached to all work tools by changing the form of the portable wireless transmission means.

It is an external view which shows the whole embodiment. It is sectional drawing which shows the inside of a portable radio | wireless transmission means. It is an external view of the portable radio | wireless transmission means which shows one Embodiment. It is an external view of the portable radio | wireless transmission means which shows one Embodiment.
