JPH10338422A - Mounting confirmation device of object to be worked - Google Patents

Abstract

PROBLEM TO BE SOLVED: To confirm a mounting situation of an object to be worked from outside by providing a means which detects changes of pressure of a support body which supports the object to be worked and outputs a signal on a movement body side and providing a detection means which outputs a predetermined signal when it detects an output signal on a reference body side separate from a movement body. SOLUTION: In a movement body 2, a handle 41 is operated after a bobbin 7 is mounted between piston rods 33 of a support body 3 to communicate a pipe 40A with a pipe 40C. Consequently, pressure in a rear chamber C becomes higher than that in a front chamber B so that the piston rods 33 advance to fix the bobbin 7. Since high pressure air passes through the pipe 40C and a pressure switch 4 is turned on in this condition, an energizing body 5 forms a magnetic field. As a result, a signal is generated by an electromagnetic phenomenon every time when the energizing body 5 approaches a proximity sensor 6 in a reference body 1 cyclically. A mounting condition of the bobbin 7 can be confirmed on the outside of the movement body 2 by confirming the signal outputted regularly.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working device for performing various operations with a moving body that moves with respect to a stationary reference body, wherein a work is mounted and locked on a support provided on the moving body side. The present invention relates to a device for confirming the attachment of a work to be checked on the reference body side.

[0002]

2. Description of the Related Art For example, there is known a working device which sets various unprocessed products (hereinafter, referred to as "work") on a turntable which rotates on a fixed base, and performs an appropriate processing operation on the work. Have been.

Of course, in such a working device, for example, the worker starts the work after firmly setting the work in a predetermined position. Even if you intend, you can inadvertently make a setting mistake. For this reason, for example, a device to which a mounting device for automatically mounting is added has been developed.

[0004]

However, even with such an automatic mounting device, if the device is broken or the mounting state is uncertain,
Since this cannot be confirmed, the work may be repelled from the rotating turntable, causing a serious accident. Under such circumstances, there is a strong demand for the development of a confirmation device that can confirm the wearing state from outside of the exercise body even during exercise (work).

[0005] In view of the above circumstances, the present invention allows the user to check the mounting state of a work object on various types of moving bodies from outside the moving body without contact, and thus to improve safety. It is an object of the present invention to provide a device for confirming attachment of a work.

[0006]

That is, according to the present invention, there is provided a reference body provided with a stationary reference plane, and a moving body which performs an appropriate relative movement with respect to the reference plane of the reference body. ,
An apparatus for confirming that a work is mounted and locked on the support by fluid pressure in various work devices including a support provided on the moving body, wherein the support is A means for detecting a change in pressure and outputting an appropriate signal is provided on the moving body side, and a detecting means for detecting the output signal is provided on the reference body side, and the mounting state of the work is confirmed on the reference body side. It is configured as follows.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram showing an apparatus for confirming attachment of a work according to this embodiment, which is applied to a cradle (a splitting plate) of a cable assembly machine. The apparatus for confirming attachment of a work according to this embodiment includes a reference body 1 fixed (stationary) to a floor or the like, a moving body 2 performing (rotating) motion with respect to the reference body 1, and a moving body 2 , A pressure switch 4 and an exciter 5, and a proximity sensor (magnetic sensor) 6 provided on the reference body 1 side. In addition, the code | symbol 7 in FIG. 1 shows the bobbin which is a to-be-worked object (work).

The reference body 1 in this embodiment corresponds to the body side of the cable assembly machine, and the moving body 2 corresponds to the cradle rotating around the line shaft. The support 3 is for holding and supporting the bobbin 7 from both sides by fluid pressure (high-pressure air in this embodiment), and includes an air cylinder 31 and a piston 3 that slides in the cylinder 31.
2 and a rod 33 attached to the piston 32. High pressure air is supplied to the air cylinder 31 from a cylinder (not shown) as a supply source via a pipe 40A, a pipe 40B or 40C. High-pressure air is sent to the side. The support 3 is attached to a rotatable body 34 rotatably supported via a bearing (not shown) on the moving body 2 side, and is connected to the motor M side of the reference body 1 via a rotary joint RJ. I have. The rotary joint RJ is a pipe in which a pipe is arranged concentrically inside a rotary shaft via a bearing, and a fluid (high-pressure air in this embodiment) flows through the pipe.

The pressure switch 4 is turned on when high-pressure air is sent in through the pipe 40C to close the circuit (shown by a broken line) S, and is turned off and opened otherwise. The exciter 5 and the proximity sensor 6 are installed in a positional relationship capable of facing each other, and the exciter 5 comes closest to the proximity sensor 6 only once each time the moving body 2 makes one rotation (one cycle), A magnetic signal corresponding to the mounted state of the bobbin 7 is transmitted and received from the exciter 5 to the proximity sensor 6 (in a non-contact state).

Therefore, according to this embodiment, the handle 4
1 is operated in a predetermined direction to adjust the valve 42 so that the pipe 40A and the pipe 40B communicate with each other. As a result, as shown by the solid line in FIG. 1, high-pressure air is supplied from the supply source through the valve 42 to the front chamber B via the pipe 40B, so that the piston 32 retracts toward the low-pressure rear chamber C, and 3 is released.

In this state, after the bobbin 7 is mounted between the piston rods 33 of the support 3, the handle 41 is operated in the opposite direction (indicated by a broken line), and the pipes 40 A and 4
And communicate with 0C. As a result, the rear chamber C immediately becomes higher in pressure than the front chamber B, so that the piston rod 33 advances, and the bobbin 7 is firmly fixed by the piston rod 33.

In this state, the high-pressure air passes through the pipe 40C and the pressure switch 4 is turned on (the state shown by the solid line), so that the exciter 5 forms a magnetic field. As a result, every time the exciter 5 periodically approaches the proximity sensor 6, a signal (current or voltage) can be generated by an electromagnetic phenomenon. By confirming that this signal is output periodically, The user can check the mounted state of the bobbin 7 outside the moving body 2.

[0013]

As described above, according to the present invention, a means for detecting a change in pressure of a support for supporting a work and outputting a signal is provided on the moving body side. Since the detection means for outputting a predetermined signal is provided on the reference body side different from the moving body, even if there is a barrier made of a non-magnetic material such as resin or glass between the reference body and the moving body, the fluid pressure and Using the magnetic action, the mounting state of the work can be reliably confirmed from the outside. In other words, troubles due to mounting mistakes, loosening or disengagement during exercise, etc. can be reliably detected, leading to a dramatic improvement in safety in various operations.
