Abstract

PROBLEM TO BE SOLVED: To automatically count the long size material mounted on a tray by counting number of the material inside of the tray on the basis of the weight per each long size material. SOLUTION: A tray 1 is mounted on a conveyor, and transferred in the arrow (x) direction of the conveyor by a roller, and position of the tray 1 is fixed by a stopper 7 of an end of the conveyor. A scale device 8 is provided between each conveyor mechanisms 2, and when the tray 1 is stopped by the stopper 7, a motor is started, and a weight meter 11 is raised so as to measure the weight of the tray 1. The weight data is held as the data, which shows the number of the long size material 12. This data is converted to the data, which shows the number of the long size material, by a converting mechanism, which is not showed in a figure. In the case where the number of the long size material is expressed with (y), weight of the tray is expressed with (x1), weight from the weight meter 11 is expressed with (x2), and the weight per each one long size material is expressed with (x3), the number (y) is obtained with a formula (y)=((x2)-(x1))/(x3).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for counting long objects such as nuclear fuel rods loaded in a tray.

[0002]

In the past, it has been customary for a person to count the long objects loaded in a container, for example, the nuclear fuel rods loaded on a tray, one by one. Therefore, it takes a long time to count, and it is easy to make a miscalculation due to a counting error. Counting was extremely difficult, especially when the loading conditions were not tidy.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a long object counting device capable of automatically counting long objects stacked on a tray.

[0004]

SUMMARY OF THE INVENTION A long object counting device of the present invention comprises a weighing device for measuring the weight of a container accommodating a long product, a weight output by the weighing device and a weight of the container. From the, obtain the net weight of the long objects loaded in the tray,
A conversion means for calculating the number of long objects loaded in the container from the net weight and the weight per one long object is provided.

The weighing device is installed in the same row as a tray conveyor composed of a plurality of conveyor mechanisms in which rollers for container transfer are mounted on a roller fixing base, and the tray support surface of the weighing scale and the rollers. And a weighing device capable of supporting and weighing the container by one of the rollers being raised or lowered with respect to the other, and the weighing scale being positioned above the container supporting surface of the roller. Can be configured as.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of the main part of a long object counting device according to the present invention. In FIG. 1, first, a large number of long objects 12, for example, nuclear fuel rods are loaded on the tray 1 as shown in FIG. 2 or 3.

The tray 1 is mounted on a tray conveyor for measuring the weight of its contents. The tray conveyor is composed of three conveyor mechanisms 2 arranged in the carrying direction. Each conveyor mechanism 2 has a roller fixing base 5 supported by a support 4 on a base 3, and a roller 6 is pivotally attached to the roller fixing base 5. The tray 1 is mounted on the roller 6 mechanically (by a transfer device (not shown)) or manually, and is transferred from the starting end to the ending end (that is, in the arrow x direction) of the tray conveyor while rotating the roller 6. It A stopper 7 is provided on the conveyor mechanism 2 that constitutes the terminal end of the tray conveyor, and the position of the tray 1 is fixed by the stopper 7. Further, the stopper 7 prevents the tray 1 from running away or falling off. Further, when the tray 1 is taken out, it is transferred in the arrow x'direction.

A weighing device 8 is installed between the conveyor mechanisms 2. The scale device 8 includes a base 9 and the base 9
It is composed of a motor 10 mounted on the top and a weight scale 11 which is vertically moved by the motor 10.
When the tray 1 is stopped by the stopper 7, the motor 10 is activated, the weight scale 11 is raised, and eventually the tray 1 is brought into contact with the tray 1. The ascent of the scale 11 is stopped when the tray 1 is slightly separated from the roller 6, and
1, the tray 1 is supported. The weight at that time is held as data representing the number of long objects 12. When this weighing is completed, the motor 10 is activated, the weight scale 11 is lowered, and the tray 1 can be taken out from the conveyor.

The data from the weighing scale 11 is converted into the number of long objects by a conversion mechanism using a microcomputer (not shown), for example. This is the number y, the weight value of the tray is x1, the weight value from the scale 11 is x2, and the long object 1
When the weight value per book is x3, y = (x2-x1) / x3. However, this is the case where the tray 1 is loaded without using a loading jig as shown in FIG.

As shown in FIG. 3, the loading jig 1 is placed in the tray 1.
In the case of loading using the load No. 3, when the weight value of the loading jig 13 is x4, y = (x2-x1-x4) / x3 is obtained.

Further, by expanding the weight data for each long object, each tray, and each loading jig in the microcomputer, an accurate conversion can be performed.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment. For example, in the above embodiment, the weight scale 11 is raised above the roller 6 so that the weight scale 11 is positioned above the container supporting surface of the roller 6 and the tray 1 can be supported and weighed. However, according to the present invention, the same state can be obtained by lowering the roller 6 with respect to the weight scale 11.

[0013]

As described above, according to the present invention, the weight of a long object loaded in a container is measured, and the number of long objects in the container is measured from the weight of each long object. By doing so, it becomes possible to automatically count the long objects loaded in the container.
