2. Description of the Related Art Conventionally, as this type of apparatus, for example,
It has two optical systems consisting of upper and lower sensors with different degrees of association with the sheet, detects a measurement optical signal and a reference optical signal for each of these optical systems, and uses these signals to detect the above-mentioned sheet. A technique for obtaining a signal corresponding to the amount of water, for example, as shown in FIGS. 5 to 7 (a schematic configuration diagram of a conventional sheet-like substance characteristic measuring apparatus) is known (for example, Japanese Utility Model Application Laid-Open No. 1-180644). Gazette and Japanese Utility Model Laid-Open No. 2-6249).

In FIGS. 5 to 7, 1 is a vertical frame usually called an F stand, 2 is a vertical frame usually called a B stand, and 3 and 4 are horizontal frames.
An O-shaped frame 5 is formed based on the conformal frames. 6 (6 ') is the upper head (6' is moving) gripped by the horizontal frame 3, and 7 (7 ') is the lower head (7' is moving) gripped by the horizontal frame 4. is there.

The heads 6 and 7 are arranged so as to be opposed to each other at a fixed interval, and are respectively attached to the frame main member (H-shaped rope) 3A in horizontal frames 3 and 4, respectively. Jack bolts J arranged at predetermined intervals
Provided to move the upper and lower sensors simultaneously in parallel so that the height adjustment (Z direction shown in FIG. 7) and the mounting position can be adjusted in the horizontal direction (X direction shown in FIG. 7) by a and Jb. The two rails (for example, the portion indicated by 3a and 3b when expressing the horizontal frame on the upper side of FIG. 7; the lower side is abbreviated, but the shape corresponding to this is naturally , But reciprocates in the horizontal direction (Y direction shown in FIG. 7).

At this time, looking at the upper horizontal frame, two rails 3a and 3b have upper rollers 6a1 and 6a1, respectively.
6a2 is locked, and upper and lower sensors are supported by rollers 6b1 and 6b2 on the left and right sides to prevent lateral displacement, and traveling is possible. Reference numeral 8 denotes a sheet that travels between the upper and lower heads 6 and 7. 9 is motor with reducer, 11 is small belt 10
Drive shafts 12a, 12b,
For example, 12b is a timing belt, 13a to 13e are reels,
14a to 14d are idlers.

In such a main part configuration, when the motor 9 with the speed reducer rotates, the vertical sensor
The rotation of the reels 13b and 13c is transmitted to the timing belts 12a and 12b via the reel 13a → the drive shaft 11 → the reels 13b and 13c through the upper head 6 and the lower head 7.
Runs and moves at a speed proportional to the number of rotations of the motor. This operation is performed by rotating the motor forward and backward.
The upper and lower sensors can be scanned left and right on the sheet surface (reciprocated in the width direction of the sheet).

At this time, the scanning width is set by commanding the measurement width in accordance with the sheet 8 using a microprocessor or the like (not shown), or an optical switch or the like for detecting the sheet width is connected to an up / down sensor. It is configured to be automatically determined by mounting it on the like.

On the other hand, a limit switch (not shown) is actually arranged in consideration of, for example, a case where the window of the optical switch becomes dirty or runs away in these command systems. By the way, at this time, as for the operation position of the limit switch due to load, inertia, etc., unless the operation position is made to be slightly variable, as a practical problem, the upper and lower heads 6, 7
Vertical frame of the upper and lower head by overrun
There is a risk of collision. Therefore, in order to avoid such a situation, a mechanical stopper (not shown) is further provided outside the limit switch. This allows the upper and lower heads to be
The collision of vertical frames has been prevented. The mechanical stoppers are provided with fixing holes (processed) based on the specifications of the device, and are fixed to the portions.

[0009]

However, such a conventional technique has the following problems.

(A) To explain the problem in detail with reference to FIG. 7, considering that one rail (for example, 3a) is adjusted in the height direction (Z direction), the measurement center of the sensor 6 is Z Move in the horizontal direction (X direction) (for example, 3a
When the sensor is lowered, the sensor rotates clockwise). By moving the other rail 3b in the height direction (Z) to correct this, the movement in the horizontal direction (X direction) can be returned to the original direction. However, to make fine adjustment in the Z direction, it is necessary to alternately move the two rails to reduce the deviation in the X direction. As described above, since the rail adjustment requires considerable skill and adjustment time, the man-hours for the adjustment cannot be ignored.

(B) Since the mechanical stopper for mechanically stopping the upper and lower heads is fixed by a method of individually installing fixing holes based on the specifications of the apparatus, the number of working steps for this is not negligible. It has become.

The present invention has been made in view of such problems of the prior art, and has as its object to provide a mechanical stopper for stopping rail adjustment and sensor movement. It is an object of the present invention to provide a sheet-like substance characteristic measuring device capable of reducing man-hours for setting and the like. In other words, when adjusting the rails in parallel, the rails for adjusting the height direction and the rails for adjusting the horizontal direction are provided separately to separate the adjustment directions. It is an object of the present invention to provide a sheet-like material characteristic measuring apparatus provided with a rail adjusting mechanism capable of minimizing mutual interference as much as possible (negligibly small). Also, regarding the setting of the mechanical stopper, when the sheet width or the center of installation is shifted, the stopper as a safety device can be easily replaced according to the operation. -To provide an apparatus for measuring the properties of a substance.

[0013]

In order to achieve the above-mentioned object, the present invention provides a method in which a seal is provided on a guide rail provided on each of the main frames of the upper and lower horizontal frames. In a sheet-like material characteristic measuring device, upper and lower sensors, which are opposed to each other so that the sheet-like material can travel within a predetermined interval, simultaneously move in parallel to measure the characteristics of the sheet-like material. A): Two pieces are vertically arranged on the frame main material via a rail support member, and one piece located at the upper part of the inside has a circular surface shape and has a height direction. The other adjustable Z-adjustment rail, which is arranged at the lower position, has a rectangular shape and is an X-adjustment rail which is mounted so as to be adjustable in the horizontal direction. And a guide rail provided between the rail support member and the Z adjustment rail. A pair of Z adjustment wedges are arranged in an intersecting manner, and a Z adjustment rail support adjusting mechanism for adjusting the Z direction of the Z adjustment rail in accordance with the wedge intersecting position, and a pair of the upper and lower sensors. A pair of main rollers and a pair of main rollers arranged at a predetermined angle with respect to the center axis of the rail and both sides of the X adjustment rail are provided on the Z adjustment rail. And a pair of side rollers. (B): When two pieces are vertically arranged via the rail supporting member on the frame main material, the surface shape arranged at the upper position is formed in a circular shape and the height direction can be adjusted. A guide rail comprising an adjustment rail, and a damper sandwiched in a central portion so as to be located at an upper position of the Z adjustment rail, and a Z rail being sandwiched at a lower portion. A sheet-like substance characteristic measuring device, comprising: a mechanical stopper mechanically stopping movement of an upper and lower head composed of a pair of buckets.

[0014]

[Function] In parallel adjustment of the upper and lower sensors, a Z adjustment rail for adjusting the height direction (Z direction) and an X adjustment rail for adjusting the horizontal direction (X direction) are separately provided. To separate the adjustment directions. Specifically, the Z adjustment laser
The upper and lower Z-rails are arranged so that they are positioned above and below the sheet of the X-adjustment rail.
The adjusting rail has a circular surface shape in order to perform adjustment in the Z direction, so that the effect of twisting of the rail is eliminated and fine adjustment can be performed in the Z direction. On the other hand, the lower X-adjustment rail is formed in a rectangular shape so that displacement in the X direction hardly occurs due to movement of the contact surface of the roller due to Z adjustment (to reduce interference).
Adjustment in the X direction is facilitated.

A main roller and a side roller are mounted on the sensor, and the main roller is mounted on a Z-adjustment rail at a pair of predetermined angles and mounted thereon. , And the side rollers are arranged in a pair so as to sandwich both sides of the X adjusting rail.

Accordingly, when the X adjustment rail is adjusted in the X direction, the sensor moves in an arc centered on the Z adjustment rail. At this time, the sensor moves in the horizontal direction (X direction). The movement in the height direction (Z direction) becomes 1/10 or less, which is a sufficiently negligible value, and the adjustment in the X direction and the adjustment in the Z direction can be separated. That is, mutual interference can be reduced as much as possible.

Furthermore, the limit switch and the mechanical stopper can be continuously and variably moved and adjusted in accordance with the width of travel of the upper and lower heads. As a result, it is possible to manufacture the apparatus without the need for a state investigation and a meeting on the user side, thereby reducing man-hours (providing an inexpensive apparatus) and eliminating special considerations for remodeling or relocating the apparatus. . At this time, it is possible to attach a stopper using a fastener such as a screw with a slotted H-shaped steel, but since it is mounted outside the shape of the H-shaped steel, In the case of a sheet break or the like, it is conceivable that the cut portion may be caught by a screw or the like, so this method is not very good. Therefore, the best shape is to be provided on the rail.

And so on.

Accordingly, when the wedge position adjusting bolt 41 is loosened, the wedges 40a and 40b are expanded by the force of the spring S, so that the Z adjusting rail 31 is lowered. , 40b are narrowed, so that the Z-adjusting rail 31 can be adjusted to a position where it rises. If both wedges are fixed by finally tightening the wedge fixing bolts 38 after such adjustment, the stability of the Z adjustment rail 31 can be ensured thereafter.

On the other hand, the X adjusting rail 32 is a rail supporting member.
