Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pneumatic transport device for conveying disparate articles of different sizes from different floors of a building to containers provided at a central collection location.

This type of pneumatic transportation device is installed in high-rise buildings such as hospitals, hotels, and department stores to streamline and mechanize the transportation of goods.

Particularly in hospitals, for hygienic reasons, they are used to pneumatically transport laundry, used instruments and bandages.

The above-mentioned pneumatic transport device has the advantage that it saves the labor required for transporting items, and at the same time, workers do not come into direct contact with bacteria-contaminated clothing, sheets, gloves used during surgery or treatment, etc. ing.

On the other hand, when planning new urban areas, it was considered to package and send items in order to separate items such as laundry at collection points from items that would be incinerated as waste at incinerators.

The above incinerators are common in urban areas, and the heat generated during incineration is
It is now used to generate electricity, heat or produce hot water.

In known pneumatic conveying devices, separate pipes are provided for laundry and waste, and it has also been proposed to use one common fan to create the vacuum required for transport in the two pipes.

However, the above type of pneumatic transportation equipment requires a large number of piping,
There are disadvantages such as the construction work requires a lot of labor and maintenance is troublesome.

The present invention has been made in view of the above points, and aims to provide a pneumatic transportation device that simplifies construction work, reduces excavation and construction costs, and further reduces operating costs.

The object of the present invention is to provide a pneumatic transport device for conveying dissimilar articles of different sizes from different floors of a building to a central collection point with containers for further processing. A chute 1 extending vertically from a common upper floor to a lower floor is provided, and two pipe lines 4 and 5 are connected to the lower end of the chute 1 via a switching valve 3.
are connected to a common horizontally extending transport duct 13 via a bottom valve 6°7, one end of said transport duct 13 is provided with an air intake, the other end is provided with a fan and an air outlet, and the nearest A switching valve 3a is installed between the pipe and the fan.
, 3b are connected to branch passages in which containers for performing the above processing are arranged, and furthermore, depending on the movement of the covers 2a and 2b provided on each floor of the chute 1, corresponding bottom valves and switching valves are connected. This is achieved by means of a pneumatic transport device equipped with a control device for movement.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a chute for transporting articles, and this chute extends vertically from the upper floor to the lower floor of a high-rise building such as a hospital, and is used to transport laundry, waste, etc. Different types of articles with different sizes are caused to fall by the action of gravity.

Covers 2a and 2b for opening and closing the two insertion ports are provided at the portions corresponding to the floors I and I[... of the chute 1.
is provided.

The above two insertion ports are for inserting laundry and waste separately.

On the other hand, two pipe lines 4 and 5 are connected to the lower end of the chute 1 via a switching valve 3.

The switching valve 3 opens one conduit and closes the other conduit according to the opening and closing of the covers 2a and 2b, and selects and sends the articles falling from the chute 1.

The lines 4, 5 are connected via bottom valves 6, 7 to a common horizontal transport duct 13.

An air intake port 14 having a damper is provided at one end of the transport duct 13, and a fan device F and an air outlet are provided at the other end. I'm trying to transport it.

Further, between the lowermost side of the transportation duct 13, that is, the closest pipe line 7, and the fan device F, there are switching valves 3a and 3.
The two branch paths are connected through the transport duct 13, and a container TXAS for storing articles is provided at a portion corresponding to the central collection position of the transport duct 13 and the branch path. The sent articles are sent to one of the respective containers TXAS according to instructions.

That is, the covers 2a and 2b, the switching valve 3, and the bottom valves 6 and 7
, and the switching valves 3a, 3b, whose movements are controlled by a control device (not shown), and the covers 2a, 2b.
By opening one of the corresponding switching valves 3,
The bottom valves 6, 7 and the switching valves 3a, 3b are moved so that the articles falling from the chute 1 are sent into the correct container in which to store them.

The transport duct 13 is usually made of a smooth pipe made of steel, cast iron, or stainless steel, and depending on the installation conditions, the transport duct 13 can be as long as 500 m+n, and is installed in an underground culvert, for example.

In this case, a viewing cover is provided at an appropriate location to visually check the inside.

As described above, according to the present invention, although the articles inserted into the chute fall due to the action of gravity, they hardly get clogged in the chute, and the articles sent to the transport duct are transported horizontally. Since the fan equipment is not large-sized, and the transportation duct is common, the excavation and construction costs can be reduced, and since the chute is common, it is not necessary to make the fan equipment large. The area is small, and the building structure is not weakened by the drilling.
