Description

[Detailed explanation of the idea] The present invention relates to a hydraulic capsule stopping device.

As shown in FIG.
In a hydraulic capsule transportation device that hydraulically transports the capsule 21 by putting the capsule 21 in the capsule 21 while running,
When stopping the pipeline 2, a stopper 22 generally made of a rod or plate-shaped solid (elastic body) is inserted from the outside.
A structure is adopted in which the capsule 21 is inserted into the capsule 0 and stopped by applying the capsule 21 thereto.

This format is very effective when the weight of the capsule 21 is relatively light.

However, when the weight of capsule 21 increases, capsule 2
1 and the inertial force generated when stopping the flow of water behind the capsule, a very large force is applied to the stopper 22.

Therefore, the stopper 22 and the mounting structure 23 may be damaged, or smooth insertion operation may not be expected.
In order to avoid this, the stopper 22 and the like must be made sturdy and large.

The purpose of this invention is to propose a hydraulic capsule stopping device that can easily stop a capsule while eliminating the need for a stopper. In the capsule transport device, the capsule stopping device has a large number of drainage holes formed in the circumference of the pipeline on the upper side in the direction of capsule transport, an annular body that covers these drainage holes from the outside, and a ring that communicates with the annular body. A drainage section consisting of a main drainage pipe is provided, and is provided on the downstream side in the capsule transportation direction of the capsule stop position, and is opened diagonally so as to spout water toward the upstream side in the capsule transportation direction around the circumference of the pipeline. A water supply section consisting of a large number of water supply holes, an annular body that covers these water supply hole groups from the outside, and a water supply pipe communicating with the kneading annular body is provided, and between the main pipe of the water drainage section and the water supply pipe of the water supply section. Furthermore, the above object is distantly achieved by interposing a water supply pump whose suction side is connected to the main pipe and whose discharge side is connected to the water supply pipe.

An example of this will be described below with reference to FIGS. 2 and 3.

Reference numeral 1 denotes a pipeline for hydraulically transporting capsules 2 by flowing water, and a capsule take-out section 3 is provided at the end of the pipeline, for example.

4 is a capsule stopping device installed at an appropriate location in the pipeline 1, on the upper side of the capsule stopping position in the direction of capsule transportation;
It is composed of a water drain section 5 that drains water flowing through the pipeline 1, and a water supply section 6 that supplies water into the pipeline 1 on the downstream side of the capsule stopping position in the capsule transportation direction.

The drainage section 5 includes a large number of drainage holes 7 formed between the pipelines 1 and an annular body 8 that covers the group of these drainage holes 7 from the outside.
and a drainage pipe 9 communicating with this annular body 8.

The water supply section 6 also includes a large number of water supply holes 10 formed in the pipeline 1 and an annular body 1 that covers the group of these water supply holes 10 from the outside.
1 and a water supply pipe 12 communicating with the annular body 11, and the water supply hole 10 is oriented on the upstream side so as to inject (or flow) water upward in the capsule transportation direction.

Here, the water supply pump 13 is provided between both parts 5 and 6.

That is, the suction pipe 14 of the water supply pump 13 communicates with the water drain pipe 9, and the discharge pipe 15 communicates with the water supply pipe.

A capsule detection device 16 is provided upstream of the capsule stop device 4, and an operation detection device 17 is provided in the capsule take-out section 3.

The capsule detection device 16 emits a detection signal a when the capsule 2 passes, and the operation detection device 17 performs an extraction operation.

Sometimes a detection signal is emitted.

The rain detection signals a and b enter, for example, an AND circuit 18, from which an activation signal is issued to the water supply pump 13.

Normally the water pump 13 is inactive, so that water passes through the capsule stop device 4.

When the capsule 2 being transported through the pipeline 1 is detected by the capsule detection device 16, a detection signal a is generated.

At this time, when the capsule ejector 3 is empty and inactive, the AND circuit 1
8 does not work.

Therefore, since the stop device 4 does not work, the capsule 2
passes through and reaches the capsule extraction section 3.

On the other hand, when the capsule take-out section 3 is in an operating state, a detection signal is generated, so that the AND circuit 18 acts and the water supply pump 13 is operated.

As a result, the water in the pipeline 1 is drained from the water extraction section 5, and then supplied to the pipeline 1 again from the water supply section 6 via the water supply pump 13, and this drained supply water is directed upward in the direction of capsule transportation. Since the capsule 2 is being injected, the brakes are applied to the capsule 2 being transported, thereby stopping it.

During this stop, when the capsule take-out section 3 becomes inactive, the detection signal is cut off, and the water supply pump 13 is stopped and the capsule 2 is transported again.

In the embodiment, a stop device 4 for stopping double feeding to the capsule take-out section 3 is shown, but this is provided for various stop requests in the pipeline 1.

As described above, according to the present invention, even if water is flowing through the pipeline and is being transported by hydraulic power, the water in the pipeline is forcibly extracted from the water outlet part by the water supply pump and drained to the water supply part. Moreover, since the water to be supplied flows upwardly from the water supply hole in the capsule transport direction, the capsule can be easily stopped between the extraction section and the water supply section without using a stopper or the like.
