Abstract

PURPOSE:To prevent a pressure gradient, etc. from being produced in air blown out by supplying high pressure air from a nozzle of a high pressure pipe to the inside of a transfer passage. CONSTITUTION:A transfer passage 2 of an air conveyer 1 is provided on its top surface with a number of air blow outlets 3 tilting toward a transfer direction, with one end of the transfer passage 2 provided with an air passage 4 forming a space for taking atmosphere in. The air passage 4 is also provided either on its side or bottom face with an opening 5 and also either to the front or rear of the opening 5 inside the air passage 4 is arranged a nozzle 7 of a high pressure pipe 6. When high pressure air is supplied from the nozzle 7 of the high pressure pipe 6 to the inside of the transfer passage 2, atmosphere is taken from the opening 5 of the air passage 4 into the transfer passage 2. As a result, the high pressure air mixes with the atmosphere to reduce the pressure of air being sent in as well as to increase the flow rate of the air sent into the transfer passage 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conveyor that utilizes high pressure air from a compressor, high pressure piping in a factory, or the like.

[Conventional technology]

Conventionally, this type of air conveyor has been provided with a large number of air outlets (3) on the upper surface of a transport path (2), for example as shown in FIG. Road (4
) is configured to blow air from a suitable blower (10).

The air blown from this blower (<10) is normally 10
Since the pressure is adjusted to about ~500 mm Aq and has a sufficient amount of air, the air is uniformly blown out from the air outlet (3) provided in the transportation path (2), and objects are transported smoothly. Therefore, the air blown from the blower (10) has been used as a power source for the air conveyor.

However, if high-pressure air with a pressure of about 1 to 10 kg/cm from a compressor or high-pressure piping in the factory is used instead of the air blown from the blower (10), the blowing pressure is too strong. In addition, since the amount of air blown is not sufficient, a pressure gradient may occur in the air blown out from the air ports (3) provided in the transportation path (2), and sometimes negative pressure may occur at some air outlets (3). Conventionally, high-pressure air from a compressor or factory piping has not been used at all as a power source for this type of air conveyor.

[Problem that the invention seeks to solve]

However, the power source of the air conveyor is a blower (10
), the equipment cost of the blower (10) itself would be high, the installation location would have to be considered, and the working environment would be poor due to noise ( There was a problem with that.

Therefore, the present invention was made for the purpose of directly using high-pressure air from a compressor or using high-pressure air from high-pressure piping in a factory.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a structure in which high-pressure air from the nozzle (7) of the high-pressure pipe (6) is transferred to the transport path (2) through an appropriate space that takes in the atmosphere.
) is supplied internally.

Note that the space has a ventilation passage (4) having an opening (5) on the side surface.
) Inside the ventilation passage (4) or having an opening (5) at the bottom.
) or inside a ventilation channel (4) having openings (5) (5) on the sides and bottom.

[Effect]

As a result of implementing the above measures, the high-pressure air supplied from the high-pressure pipe (6) mixes with the atmosphere taken in through the space, the air blowing pressure decreases, and the air blowing amount increases, leading to the transportation route (2). Air is blown inside.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be explained below with reference to the drawings showing examples.

A large number of air outlets (3) are provided on the upper surface of the transport path (2) of the air conveyor (1) so as to be inclined in the transport direction, and furthermore, in the example shown in FIG. (2
), and in the example shown in Figures 2 and 3, a ventilation passage (4) is provided at the bottom of the approximately central part of this transport passage (2) to form a space for taking in the atmosphere. There is.

Note that this ventilation path (4) is not limited to the illustrated embodiment, and may be provided on the side or top surface of the transportation path (2).
) is provided with an opening (5) on the side or bottom, and the nozzle (7) of the high pressure pipe (6) is arranged inside the ventilation passage (4) at the front or rear position of the opening (5). ing.

Note that the opening (5) may be provided not only on either the side surface or the bottom surface but on both the side surface and the bottom surface.

Therefore, when high pressure air is supplied into the transportation path (2) from the nozzle (7) of the high pressure pipe (6), the ventilation path (4
) Atmospheric air is taken into the transportation route (2) through the opening (5) of the opening (5), and the high-pressure air mixes with this atmosphere, reducing the blowing pressure and increasing the amount of air being blown into the transportation route (2). Ru.

〔Effect of the invention〕

The air conveyor using high-pressure air of the present invention is configured as described above, and uses high-pressure air directly from a compressor instead of blowing air from a blower.
Even if high-pressure air is used from the high-pressure piping in the factory, it is possible to reduce the blowing pressure and increase the blowing volume. There are no problems such as slopes, etc., and there are problems such as high equipment costs, the need to consider the installation location, etc., and noisy noise. There is no problem that the lJ environment etc. will deteriorate.
Has excellent effects.
