Abstract

PURPOSE:To aim at making attitude control into automation, by installing at least three conveyor belts in line so as to have each parallelly aligning spot with each other in order along a conveyor line, while installing a stage between adjacent belts at each of these aligning spots, and installing an obliquely crossed conveying guide member. CONSTITUTION:Conveyor belts 5 (5a-5c) constituting a conveyor line 2 are installed in line so as to have each parallelly aligning spot with each other in order, besides in a zigzag setup. Each conveyor belt 5 is driven and rotated by motors 7a-7c so as to be speed-governable separately, while at the said spots A-C, these belts are approximated with an adjustable interval 10 each, and installed as to set the specified step difference with one another. Each of these belts 5 is tilted at the specified angle so as to cause a delivery side belt to be situated lower than a receiving side belt 5b in terms of horizontality. And, a conveying guide member 4 consisting of a symmetrical pair of guide plates 4a and 4b is set up just above the conveyor belts 5 so as to form an obliquely crossed part S at these parallelly aligning spots A-C.

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to cylindrical bodies such as nuclear fuel pellets that are continuously loaded into the cladding tubes of nuclear fuel rods, and is useful for automatically supplying cylindrical bodies such as nuclear fuel pellets, etc. to the next process. The present invention relates to an apparatus in which the cylindrical body in various postures is automatically corrected and controlled to assume a desired posture during the transportation process.

[Prior Art] Generally, nuclear fuel elements for light water reactors such as PWR type and BWR type contain uranium dioxide powder (UO
Nuclear fuel pellets in the form of cylinders are obtained by high-temperature sintering of the compacted product in 2), and after processing such as grinding on the circumferential side surface, inspection is carried out. The one with many insertions into is used.

Therefore, in order to grind and insert the fuel pellets, it is required to transport the fuel pellets to a desired location at 1 gi in a desired attitude. However, the fuel pellets are porous in order to minimize the release of gas such as FP gas into the cladding tube, and are therefore prone to brittle fracture, which is a characteristic of ceramics in general. As a result, defects such as damage may occur on the end or side surfaces of the parts, making it inappropriate to use a commonly used vibrating parts feeder for conveyance and supply.

In addition, when using this vibrating parts feeder, although its posture can be controlled, there is a possibility that powder may be generated due to friction between the nuclear fuel pellets, which will only lead to increased contamination within the controlled area. However, in the case of the same feeder, if more than a certain amount of fissile material gathers, the nuclear fission chain reaction will continue (reaching criticality), so there are handling controls to prevent this from happening.
In other words, criticality control problems also arise.

Therefore, as is also known, the nuclear fuel pellets are arranged in an upright state (standing on the bottom) on the rotating disk of a disk feeder, and a conveyor belt is installed in the tangential direction of the circumference of the disk. At the same time, a step difference may be provided between the circular plate and the conveyor belt, whereby the fuel pellets are laid down so that the circumferential side surface is in contact with the conveyor belt, and conveyance can be continued in this changed position. It is being done.

However, when transferring using this disc feeder, the nuclear fuel pellets are not in an upright state on the 0-rotation disc, and if they are lying on their side, they will end up in an upright state on the conveyor belt. Therefore, the task of feeding and placing the pellets onto the disk becomes troublesome, and when the pellets are transferred to the conveyor belt again, the pellets change from an upright state to a sideways state. It would be fine as long as it is transported, but it may end up lying on its side perpendicular to the transport direction, and due to such variations,
Reliable control of a constant posture has become difficult, and this is a major obstacle to automating alignment and conveyance for the next process.

Next, in order to explain the movement when conveying the cylindrical body 3 using this device, the cylindrical body 3 is erected in a position where the bottom surface 3a is placed on the conveyor belt as shown at the left end of FIG. The state is called the circumferential side surface 3b of the cylindrical body 3 as shown in the center of the figure.
is in contact with the conveyor belt, and the axis of the cylinder 3 is orthogonal to the conveyance direction, which is a sideways perpendicular state, and as shown on the right side, the axis is horizontal and the axis of the cylinder 3 is conveyed. The case where it is parallel to the direction will be referred to as a sideways parallel state (normal state).

As shown in FIG. 5 (A), the conveyor belt 5a on the current delivery side
When the cylindrical body 3 is transferred from the receiving side to the receiving side conveyor belt 5b, of course, all the conveyor belts are driven by an electric motor in the direction of the arrow, and the cylindrical body 3 is in an upright state on the conveyor belt 5a. For example, the state is maintained in the transport direction, and then the transport path 4 at the parallel alignment point A is transferred.
Since the conveyor belt 5b is arranged in a row with the belt gap 10 in FIG. It will be transported in the horizontally perpendicular state shown in the intermediate position.

Now, when we investigate the above-mentioned step difference X, we find that the inclination of the circumferential side surface 3b of the cylindrical body 3 with respect to the plane perpendicular to the upper surface of the conveyor belt 5b on the receiving side is θl, as shown in FIG. , if the inclination of the bottom surface 3a of the cylindrical body 3 with respect to the belt 5b is 02, the limit condition for the cylindrical body 3 not to fall from the upright state is θ1-02, and furthermore, when the cylindrical body 3 does not fall down from the upright state, it is θ1-02. Since the conditions for control are θ1 and θ2, let the diameter of the cylindrical body 3 be d and its height be h.

According to the above-mentioned theory, in the case of the conveyor belt (5a5b) having the height difference X, the center of gravity G of the cylindrical body 3 of the nuclear fuel pellets etc. will move, and the fuel pellets etc. will stand up. This means that the posture is controlled from a state to a sideways state.

Next, as shown in FIG. 5(B), by setting the conveying speeds va and vb of the conveyor belts 5a and 5b to predetermined speeds va-vb=k, the cylindrical body 3 is the conveyor belt on the delivery side.
When transferring from 5a to the receiving side conveyor belt 5b, a moment as shown by arrow a2 is generated due to the speed difference k, and as a result, the cylindrical body moves to the receiving side conveyor belt 5b.
When transferring to the conveyance guide section 4, the direction is changed by 90 degrees from the horizontally perpendicular state to the horizontally parallel state shown at the right end of FIG. The object is then transported in its original position.

In addition, when transferring the above, the transfer bell) 5a on the delivery side
Assuming that the upper cylindrical body is in the normal posture as described above, in this case the twisting moment that occurs during transfer will be minimal, so the nuclear fuel pellets will be transferred to the receiving side while maintaining almost the normal posture. The object then transfers onto the conveyor belt 5b, remains on the conveyor belt 5b, and continues to be conveyed in an unchanged posture thereafter.

By setting the conveyor belt 5b on the receiving side with respect to a to be higher than the horizontal plane, at an angle of about 5° to 15° with respect to the horizontal, transfer and conveyance of fuel pellets, etc. can be made even smoother.

It is preferable to use a suitable combination of polyester, polyurethane laminated on polyester, or the like.

In addition to preventing the generation of powder due to fuel pellets colliding with each other, criticality control is properly carried out, and there are fewer machines where workers directly handle fuel pellets, reducing the amount of radiation exposure for workers. This can be significantly reduced.
