2. Description of the Related Art As a conventional belt measuring device, a V-belt inspecting device is mainly known.
It is disclosed in Japanese Patent No. 56620. It hangs on a movable drive pulley and driven pulley on a V-belt,
After the distance between the shafts of the driving pulley and the driven pulley is measured while running while applying a predetermined tension, if the measured value is outside the set range, the side surface of the belt is polished.

Further, in the case of measuring the size of a conventional flat belt having a core wire, a flat belt having a core wire is suspended from a conventionally fixed drive pulley and a movable driven pulley,
After applying a constant load to the driven pulley side and rotating the flat belt a number of times, the distance between the drive shaft and the driven shaft was measured. If the distance between the shafts was within a predetermined range, it was judged as a passing product. on the other hand,
In the case of measuring a flat belt having no core wire, a constant extension, not a constant load, is applied by the movement of the driven pulley, and then the distance between the drive shaft and the driven shaft is measured.

[0004]

However, when measuring the dimension of the conventional flat belt, the distance between the drive shaft and the driven shaft is at most the axial distance. In the recent dimensional measurement of thin flat belts that do not have a core wire, it becomes impossible to maintain a certain quality unless the width, thickness, warp, and load applied to the belt are measured in addition to the distance between the shafts. Moreover, when a flat belt having a core wire and a flat belt having no core wire are mixed, a constant load is applied to the flat belt having the core wire, and a constant stretch is applied to the flat belt having no core wire. The measurement conditions had to be given and different belts had different measurement conditions, so two types of measuring machines had to be prepared.

The present invention solves such a problem, and it is possible to selectively measure whether the measurement condition is constant load or constant extension.
Another object of the present invention is to provide a belt measuring device capable of measuring the length, width, thickness, warpage, load applied to the belt, and the like of the belt.

Further, according to the present invention, the moving pulley is applied with a load in a direction opposite to the direction of the load applied by the load adjusting section, or the moving load section in which the load adjusting section slides on the shaft by the prime mover. , A load-fixing cylinder that blocks the load on the connecting member, and a stopper plate that stops swinging, or the reel in which the pulley extension part engages the connecting member makes the reel movable in a certain direction. This includes cases where the amount of movement of the pulley can be adjusted, and cases where the moving pulley of the belt mounting portion slides on the guide rail and is equipped with an opening / closing plate having a lock portion.

Further, according to the present invention, in a belt measuring device for measuring a belt length, width, thickness, warp, load applied to a belt, and the like, a belt mounting portion having a fixed pulley and a moving pulley, and a support shaft are provided.

In the present invention, the position of the moving load portion is adjusted to swing the load adjusting portion in a seesaw shape around the support shaft, and a constant load can be applied to the belt by the connecting member. By interrupting the transmission of the force to the connecting member by operating the load fixing cylinder provided on the shaft and bringing the tip of the shaft into contact with the stopper plate, move the reel of the pulley extension and pull the connecting member. The pulley can be moved to give a constant tension to the belt, and these measurement conditions can be selectively given by the same device. In addition, since the moving pulley is applied with a load in the direction opposite to the direction of the load applied by the load adjusting unit, when the position of the moving load unit of the load adjusting unit returns to its original position after measurement, the moving pulley will also move. It automatically returns to the start position, making it easy to restart measurement.

The opening / closing plate 18 is effective for avoiding the cantilever of the movable pulley 11. This opening / closing plate 18 is a door 2
When pulling out the knob 21 provided at the center of 0,
The fitting of the lock portion 22 having the concave-convex engagement structure is released, the door 20 can be inverted to open the entrance, and the measuring belt 9 can be attached. The lock portion 22 is composed of a concave portion 24 having a plurality of groove portions 23 on the shaft connected to the knob portion 21 and a fixed convex portion 25 engaging with the groove portion 23. When the door 20 is pushed in and closed after the measuring belt 9 is attached, the movable pulley 11 is stably supported by both shafts.

The moving pulley 11 is connected to the load adjusting portion 3 via the pulley extension portion 4 by a flexible connecting member 25 such as an aramid fiber cord or a wire, as will be described later, and is movable downward. In addition, it can be moved upward by connecting to another connecting member 25 having a balance weight 26 that applies a load in the opposite direction. When the load balance is lost due to the operation of the load adjusting unit 3, the moving pulley 11 moves upward and returns to the initial position.

In the load adjusting section 3, as shown in detail in FIGS. 1 and 5, a ball screw 31 into which a moving base 30 is fitted,

By applying it to the plate 42, the load transmitted to the connecting member 25 is blocked. In this state, the reel 45 around which the connecting member 25 of the pulley extension section 4 is wound is moved by the prime mover 46 on the axis of the ball screw 47, and the connecting member 25 is pulled or pulled back to set the moving amount of the pulley 11.

When the extension applied to the measuring belt 9 is removed, the rod 44 of the load fixing cylinder 43 is retracted to open the tip member 41, and the balance of the vertical pulling force applied to the moving pulley 11 is reversed. Then, the moving pulley 11 moves upward. These measurement conditions can be arbitrarily selected with the same device. This is the moving pulley 1
Since 1, the pulley extension part 4, and the load adjusting part 3 are connected in series via the connecting member 25, such an operation can be arbitrarily selected.
