Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a measuring instrument mounting device for always mounting a measuring instrument or a detector on a measurement object in the same state.

(Prior Art) In the industrial field, various measuring instruments and detectors (only measuring instruments are described below as representatives) are used.
Many of these need to be removed from the installation position and then reattached to the same position for measurement or repair purposes.In this case, depending on the object to be measured, it is necessary to always attach it in the same position with high accuracy. is there.

By the way, a light emitting device and a light receiving element are used for the color difference meter, and the reflected light from the measuring object is received to measure the color difference. In this case, it is necessary to always mount the measuring device at an exact right angle to the object to be measured. However, since the measured value changes depending on the ambient temperature and elapsed time, it is necessary to adjust the reference point each time it is measured.Each time it is removed, calibration and adjustment of the reference point are performed, and the mounting position and The angle must be adjusted accurately.

FIG. 2 shows a conventional mounting device for a measuring instrument of this type.

In the figure, reference numeral 1 denotes a measuring head of a color-difference meter, in which a mounting seat 4 is sandwiched between an upper flange 3a fixed to a band 2 wound around the main body and another lower flange 3b, and a wing nut 5 is used to attach both. By fastening the flange, the tip 1a of the measuring head is attached so as to hit the glass window 7 formed in the container 6 of the measuring object (for example, flour) which is the measuring surface at a right angle. Reference numeral 8 is a fiber cable for transmitting the measurement light to the measurement head 1.

When such a mounting device is used, a liner is used to mount the measuring head 1 so that the tip 1a of the measuring head 1 is at a right angle. However, it is difficult to obtain the precision of the mounting angle, and the tip of the universal joint is mounted on the liner. Although a method of screwing the measuring head is also used, there is a problem that the angle adjustment is difficult and troublesome.

(Object and Structure of the Invention) The present invention has been made in view of the above points, and an object thereof is to provide a measuring device mounting device which can be easily mounted and dismounted and whose mounting angle can be accurately determined. In order to achieve this, an attachment member having a first surface that comes into contact with the measurement surface and a second surface that is accurately formed so as to have a predetermined positional relationship with the first surface is used, and a measuring instrument is used. While holding one end of the contact member against the second surface of the attachment member, the other end is engaged with the holder to elastically press the measuring instrument in the direction of the measuring surface, and in this state, the holder is elastically coupled. The support frame is configured to be fixed to the mounting seat.

(Example) Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a mounting device according to the present invention, in which the same reference numerals as in FIG. 2 denote the same components.

A support ring 10 is fixed to the upper flange 3a so that the measuring head 1 can pass through it loosely.
One ends of the three springs 11 are attached at equal intervals along the circumference of 0, and the other ends of the springs 11 are attached to the collar 12a of the annular holder 12. This holder 1
2 also has three hooks 12b at equal intervals along the circumference.
Is provided.

On the other hand, an adapter cap attachment 13 is used to attach the measuring head 1. This attachment 13 is a short cylindrical sleeve and has two end faces 13b and 13c which are formed at a right angle to the side peripheral face 13a with high accuracy.

Next, a procedure for attaching the measuring head 1 of the colorimeter to the measurement object will be described.

First, one end surface 13c of the adapter cap attachment 13 is applied to the tip 1a of the measuring head 1 so that the entire support ring 1
After passing through 3, the adapter cap attachment 13
The tip (left end in the figure) end surface 13 b of the above is applied to the glass window (that is, the measurement surface) 7 of the container 6. In this state, the holder 12 is applied to the rear portion of the measuring head 1 so that its hook 12b abuts the rear end (right end in the figure) of the head 1, and three springs are provided between the support ring 10 and the collar 12a of the holder 12. Cross over 11. Next, by moving the support ring 10 forward (to the left in the figure), the measuring head 1 itself receives a forward (leftward in the figure) force by the spring 11, and the adapter cap attachment 13 causes the glass window (measuring surface) 7 to move. In this state, the wing nut 5 is turned to tighten the upper flange 3a and the lower flange 3b to the mounting seat 4. Even if the upper and lower flanges 3a and 3b are properly mounted on the mounting seat 4, the measuring head 1 is pushed forward by the force of the spring 11 and positioned on the glass window 7 via the adapter cap attachment 13. Therefore, it can be mounted at a right angle to the measurement surface with high accuracy.

When the measurement head 1 is once attached in this way and then removed from the measurement surface for calibration with a standard white plate, loosen the wing nut 5 to remove the lower flange 3b, and move the upper flange 3a rearward (rightward in the figure). For example, the force of pushing the measuring head 1 forward by the spring 11 is released, and the holder 12 is also released from the measuring head 1.
The adapter camp attachment 13 can be removed from here. After that, the main body of the measuring head 1 can be manually applied to a standard white plate which is easily prepared for the configuration.

To reattach the measuring head 1 to the measuring surface after calibration, the tip 1a of the measuring head 1 is to be mounted as in the case of the above-described mounting.
Insert the adapter cap attachment 13 into the
Move the upper flange 3a forward (to the left in the figure) by hooking the hook 12b of the holder 12 to the rear end of the head 1, and when the predetermined position is reached, turn the wing nut 5 to tighten the upper and lower flanges 3a and 3b. Good. As a result, the measuring head 1 has an adapter cap attachment 1
Since it is positioned on the glass window (measurement surface) 7 via 3, it is attached at the same angle as before removal.

In the above embodiment, both the support ring 10 and the holder 12 are the measuring head 1.
Although the ring shape is adapted to the outer shape of, the shape is not limited to this, and other shapes may be used. Further, the number of springs 11 stretched between the support ring 10 and the holder 12 and the number of hooks 12b provided on the holder 12 are not limited to three in the embodiment. Further, the means for fixing the support ring 10 is not limited to the method of fixing the two flanges 3a and 3b to the mounting seat 4 with the wing nut 5.

Further, the present invention is not limited to the detector, the sensor and the optical type in addition to the measuring device, and the two surfaces 13b and 13c of the adapter cap attachment 13 do not necessarily have to be parallel as in the embodiment. It may be formed in a predetermined positional relationship.

(Effects of the Invention) As described above, according to the present invention, the first surface abutting on the measurement surface and the second surface accurately formed so as to have a predetermined positional relationship with the first surface. Using an attachment member having a surface, one end of the measuring instrument is kept in contact with the second surface of the attachment member, and the other end is engaged with a holder to elastically press the measuring instrument in the direction of the measuring surface. The support frame that is elastically connected to the holder is fixed to the mounting seat in this state, so it is easy to remove and install the measuring instrument, and the mounting angle when re-installing does not cause troublesome adjustment. It can be done with the same precision as before removal.
