Description

[Detailed description of the invention] This invention is a device having a pneumatic tube in which a plurality of garbage capsules are successively pneumatically fed, and these garbage capsules are sequentially removed one by one from the terminal end of the pneumatic tube. It is an object of the present invention to provide a take-out device that allows safe take-out.

When garbage collection in condominiums, high-rise buildings, etc. is carried out by capsule pneumatic transportation, pneumatically conveying the capsules filled with garbage one by one to the collection point at time intervals is a problem when residents handle the capsules. This is extremely impractical in view of the convenience and improvement of collection ability by pneumatic transport, and it must be taken into consideration that the garbage capsules will continue to be pneumatically transported.

However, when taking out the capsules from the terminal end of the pneumatic pipe, which is the collection point, it is necessary to take out the capsules one by one in order to load them onto a transport vehicle or the like.

This situation also applies to cases where capsules made of paper or the like are automatically put into an incinerator.

This invention is a method of solving the above-mentioned demands with respect to a means for taking out the capsule, and this invention will be explained below with reference to the illustrated example.

That is, B is a terminal chamber connected to the terminal end of the pneumatic tube A, and the pneumatic tube A serves as a passage for transporting air to the capsule by vacuum suction through the suction tube H.

The device according to this invention has such a terminal chamber B, a palate d of the terminal chamber B, and an extraction control device as described below.

First, starting from the terminal chamber B, an endless bell (D) is provided inside the terminal chamber B.

The endless belt D receives the capsules K (located at C) discharged from the end of the pneumatic pipe A and conveys them.
It is driven by motor M1.

In the illustrated example, the capsule is a rectangular cardboard tube with a total length of 40 cm, and in this case, the length of the conveying surface of the endless belt D only needs to be approximately 2 m.

There is also a capsule guide passage G inside the terminal chamber B, and this guide passage G guides downward the natural fall of the capsule K (located at C,) which is discharged from the end of the endless bell D. Therefore, when a capsule at position C1 falls, it naturally affects the diving posture as shown in the figure, so the wall of guide path G smoothly guides the falling capsule downward in the diving posture. Design the form in such a way that it can be done.

Next, an outlet E is opened at the lower end of the guide passage G, and the palate d has a palate opening/closing device F for sealing the outlet E from below.

The palate opening/closing device F in the illustrated example is based on a pneumatic cylinder.

Finally, regarding the above-mentioned take-out control device, this device has the following features:
In synchronization with the ejection of the capsule K from the end of the endless bell (D), a command is issued to stop the operation of the suction source (such as a vacuum pump) and the endless bell) D, and after a certain period of time has elapsed, a command is issued to the palate opening/closing device F. It has a signaling device for supplying an opening command.

That is, in the illustrated example, Sl is a sensor of this signal device, and has a relay (not shown) that detects the capsule that has arrived at the position of C and cuts off the drive current to the motor M0 and the intake source V. ing.

This relay activates a timer (not shown), and opens the air supply valve to the pneumatic cylinder, which is the palate opening/closing device F, after a certain period of time.

The operation of the device according to this invention will be explained below.

Initially, the palate d is closed, and the terminal chamber B is exhausted through the control valve GV and the intake pipe H by the operation of the intake source ■.
It is also assumed that the endless bell) D is being operated.

The plurality of capsules filled with garbage and thrown in are sucked by the vacuum and advance inside the pneumatic tube A toward the terminal end, but according to experiments, they follow each other at intervals of about 2 to 10 cm. It is coming.

The capsules that have advanced to position C, which is the end of the pneumatic pipe A, are placed on the conveying surface of the endless belt D by the inertia of running, and then, as shown in the figure, the capsules are moved forward by the endless belt D. .

When the leading capsule is about to be ejected from the end of the endless bell (D), the sensor S1 of the above-mentioned take-out control device detects this at the position C1, and therefore the intake source is started at the same time as the endless bell (D) is stopped. will also be suspended.

The capsule that has arrived at position C1 assumes a diving position, falls down the guide passage G due to its own weight, and is exposed to the closed palate d.
placed on top.

The following several capsules come to rest on the conveyance surface as the endless bell (D) stops.

Since the intake air to the pneumatic pipe A is stopped due to the operation of the intake source V being stopped, even if there is a subsequent capsule, it will stop at the position C, thus preventing a rear-end collision with the capsule already on the endless bell (D). be spared.

After a certain period of time after the leading capsule reaches position C1, the palate d is opened, and the capsule (position C2) that has fallen onto the palate d is discharged downward from the outlet E of the terminal chamber. (Position C3) is done.

J is a roller conveyor driven by motor M2, which is used to transfer the ejected capsules laterally.

The operation of the roller conveyor L is controlled by a sensor S2 that detects the capsule at the position C3 and changes in the detection current of the sensor S2.

0. Each L is a guide plate that safely guides the falling capsule onto the roller conveyor J.

The capsules discharged from the roller conveyor J are loaded onto a truck or the like.

S3 is a sensor that detects when the capsule is moved to the side from directly below the outlet E by the roller conveyor J, and the detection current of this sensor causes the closing of the palate d and the subsequent endless bell) D and A command is given to restart the operation of the intake source ■.

In this way, according to this invention, the garbage is filled and
- The capsules traveling as a group in tracking in the pneumatic pipe remain on the conveying surface of the endless belt in the same tracking manner, and until one of the leading capsules is discharged from the terminal chamber B, the other capsules remain stationary in the terminal chamber. By stopping the capsule in the pneumatic tube before the terminal chamber, it is prevented from colliding with the capsule in front.

Therefore, the capsules can be safely removed one by one at appropriate time intervals and loaded onto a truck or the like.

Thus, according to this invention, it is possible to develop a garbage collection means in which a plurality of garbage capsules follow the pneumatic pipe as a group, and improve the garbage collection ability by pneumatic transportation of garbage capsules. The practical benefits it contributes to are enormous.
