Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pneumatic container that can be used to automate a pneumatic device used for transferring nuclear material analysis samples in nuclear material handling facilities.

It is desired that nuclear material handling work be automated in order to reduce radiation exposure of workers and contamination, and pneumatic pumping devices have been introduced as a method for transporting analysis samples to analysis laboratories in nuclear material analysis work. has been done.

However, ``the handling of the pneumatic containers used in pneumatic pumping devices and the loading and unloading of materials from the pneumatic containers are performed by humans, and there are currently no products on the market that are suitable for automation.
The present invention was made in view of the above circumstances, and its purpose is to provide a pneumatic container that can automate the loading and unloading of transferred materials and that can safely transfer nuclear materials and the like.

The present invention provides an inner container having a lid, an outer cylinder that houses the inner container, has a guide band around the outer periphery, and has one end closed.
The outer cylinder has a first locking mechanism that is inserted from the entrance end of the outer cylinder to engage and clamp the inner container within the outer cylinder to removably fix the outer cylinder, and is removably fixed to the table. and a bottom cup having a second locking mechanism that presses the first locking mechanism against a lock pin provided on the bottom cup when the second locking mechanism is fixed to the table. A lock pin holder and a pusher operated from the back side of the table are used to operate the lock pin holder and release the lock pin from engagement with the outer cylinder. This is a pneumatic device made of conductive rubber.

That is, according to the present application, since the outer cylinder is configured without any protrusions around it, it is possible to store and transfer an inner volume having a diameter close to the inner diameter of the transfer tube, and moreover, it is easy to put in and take out the inner container. This can be easily done by operating a clamper installed on the table and a busher installed on the back side of the table, so it can be automated to safely transfer nuclear materials, etc.

An embodiment of the pneumatic container according to the present invention will be described below with reference to FIG.

In Fig. 1, ``the outer cylinder with the lower end open □'' 2 is the bottom cup inserted into the lower inner surface of the outer cylinder 1, 3 is the inner container mounted on the bottom cup 2, and 4 is the inner container 3. With the lid,
For example, it is made of a material such as conductive rubber.

5 is a lock pin inserted at the bottom of bottom cup 2,
A groove la formed on the lower inner surface of the outer cylinder 1 is locked.

6 is a lock pin holder, 7' is a spring 8, a stop ring 9 is a table turtle 8, 11 is a clamper, and a shaft 2 is a pusher.

9~Group 2 is used to connect the outer tube turtle and bottom cup 2 and to separate them.

Turtle 3 and turtle 4 are guide bands made of felt or the like. Next, the effects of the above pneumatic container will be explained.

In other words, "Put nuclear material etc. into the inner container 3 made of metal such as stainless steel and cover with the lid 4. The lid 4 is made of conductive rubber etc., and when powder etc. is put into the inner container 3, static electricity will cause It prevents powder from adhering and seals the inner container 3 with its elastic force.The bottom cup 2 includes a lock pin 6, a lock pin presser 6, a spring 7, and a stop ring 8. As a result, the lock pin presser 6 is pressed toward the stop ring 8. In this state, the gap between the head of the lock pin 5 and the lock pin presser 6 is small, and the tip of the lock pin 5 protrudes from the bottom cup 2. The protruding portion of the lock pin 5 enters the groove 1-a provided inside the outer cylinder 1 and locks the outer cylinder 1 to the bottom cup. Table 9 as shown in Figure 1
A pneumatic container is placed on top, the bottom cup 2 is clamped with clampers 10 and 11, and the pusher 12 is raised to push up the lock pin presser 6.

As a result, the gap between the lock pin presser 6 and the head of the lock pin 5 becomes large, so if the outer cylinder 1 is grasped and pulled up with an automatic hand (not shown), the lock pin 5 can be moved to the outer cylinder 1.
The inner surface of the bottom cup 2 is pushed into the bottom cup 2, and the bottom cup 2 and outer cylinder 1 are unlocked and can be separated.To connect the outer cylinder 1 and bottom cup 2, place the bottom cup 2 on a table Clamp the top with the clamper Kameyama Kame, then raise the pusher turtle 2, and with the lock pin presser 6 pushed up, load the inner container 3 with the lid 4 on.
Further, the outer cylinder 1 is lowered until the lid is touched, and then the pusher weight 2 is lowered.

At this time, the lock pin presser 8 is pushed down by the spring y' until it hits the stop ring 8, and at the same time the lock pin 5 is pushed out and the outer cylinder turtle is locked. The pneumatic container in which the outer cylinder 1 and the bottom cup 2 are combined is grabbed by a hand of an automatic machine (not shown), releases the clamper turtles 0 and 11, and is loaded into a transmitter of a pneumatic device (not shown) and transferred. It is something that Figure 2 shows the state of the pneumatic container during transport, and the symbols are the same as in the blind diagram, and it travels in the direction of the arrow.

Turtle 5 is a pneumatic tube.

When the pneumatic container is running, the outer cylinder 1 is locked to the bottom cup 2 by a lock pin 5 and a lock pin presser 6, and this lock will not be released unless the lock pin presser 6 is pushed.

Therefore, for example, the nuclear material contained in the inner container 3 is not scattered into the pneumatic tube 15. In addition, even if the outer cylinder 1 were to come off, the inner container 3 is sealed by the lid 4, and the nuclear material will not scatter and contaminate the pneumatic device. Since the turtle is made of rubber and takes advantage of its elasticity, it is easy to automate.

In this way, it is possible to automate the loading and unloading of transferred materials into the pneumatic container, and the double container structure allows for safe transfer without contaminating the inside of the pneumatic pipe with nuclear materials, etc. .

In this embodiment, the lock pin 5 is used in the lock mechanism, but the effect will not be impaired even if a steel ball or the like is used, for example.
