Description

[Detailed Description of the Invention] This invention relates to a measuring traveling device used for traveling a measuring instrument.

When measuring powder flowing on a belt conveyor or the moisture content or temperature of paper during papermaking without contact, fixing the measuring device at one point allows you to measure objects that are widely distributed. It was not possible to measure the entire area, which was a problem in terms of quality control. For this purpose, a running rail has been provided, and the measuring device has been suspended from the running rail via rollers or the like and is made to run. However, there are problems in that the roller becomes difficult to rotate due to the weight of the measuring device, or it is difficult to maintain a constant measurement distance between the measuring device and the object to be measured.

The purpose of this invention was made in view of the above points, and the measuring track is slidably held by an open linear ball bearing on a round bar fixed to the inner bottom surface of the channel steel via a support. It is an object of the present invention to provide a measuring traveling device suitable for traveling a measuring instrument by providing a body.

FIG. 1 is an explanatory front view showing one embodiment of this invention. 1 is a channel steel with a substantially U-shaped cross section and is open at the bottom; 2 is two drawn round bars; It is fixed with bolt 3. An open linear ball bearing 4 is provided to surround this round bar 2, and this open linear ball bearing 4 is provided at the top of a measurement traveling body 5 with a measuring instrument 6 suspended at the bottom. There is.
Then, as shown in the side explanatory view of FIG. 2, the measuring instrument 6 is suspended from the measurement traveling body 5 and is attached to the channel steel 1 in a direction perpendicular to the object to be measured 7 flowing in the direction of arrow A. An open linear ball bearing 4 provided on a measurement traveling body 5 slides on the provided round bar 2, and the measurement traveling body 5 is moved to perform reciprocating scanning by an external drive mechanism (not shown).

FIG. 3 is a detailed view of the round bar holding part, and the strength of the spring 22 between the column 21 and the channel steel 1 can be adjusted by the tightening strength of the bolt 3 at the top of the channel steel 1. The height of the round bar 21 can be adjusted.

FIG. 4 is a front view and a side view b of the open linear ball bearing 4, in which a large number of ball bearings 42 are slidably held inside a cylindrical holding part 41. The round bar may not have a circular cross section as shown in FIG. 5a, but may have a shape in which an open linear ball bearing 42 with a notch along the longitudinal direction as shown in FIG. 5b can slide along its circumference. .

As detailed above, this invention consists of a measurement traveling body that is slidably held by an open linear ball bearing on a round bar that is fixed to the inner bottom surface of a channel steel via a support. It is a traveling device.

Therefore, since open linear ball bearings are used, there is no risk that running will be hindered even if a load is applied. Also, if you install a height adjustment mechanism such as fixing a round bar to the column via a spring, etc.
The height between the measuring device suspended from the measurement traveling body and the measuring surface can be kept constant at all times, allowing accurate measurement.
