Description

[Detailed Description of the Invention] [Field of Application in Confectionery] The present invention relates to an air purifying device that supplies clean air to manufacturing equipment, and particularly to air cleaning equipment for line-shaped manufacturing equipment such as various manufacturing lines and transportation lines. The present invention relates to an air cleaning device suitable for.

[Conventional technology]

Figure 25 shows an example of a production line before air cleaning measures were taken. Line-shaped air purification as shown in Figure 25 is shown in Figure 26,
As shown in FIG. 27, this has been done by making the entire room a clean room, or by locally cleaning the entire area including the production line and the workers involved in the production line. Note that FIGS. 20 and 21 show an example in which there are several manufacturing lines in one room.

[Problem that the invention seeks to solve]

In the method of making the entire room into a clean room with lines as shown in FIG. 26, there is a problem that the volume to be heated and cooled in addition to air purification becomes large (e), resulting in enormous power costs.

Furthermore, since there are workers who are a major source of emissions in the clean area, there is a risk that the dust emitted from them will fall onto lines that require a high level of cleanliness.

Additionally, in terms of equipment costs, there was a problem in that walls, ceilings, ducts, and air-conditioning work, other than direct air purification equipment, accounted for a large proportion of equipment costs.

In the system generally referred to as a unit clean room shown in Figure 27, the target volume is smaller than the clean room described above, reducing power and equipment costs.
Since the workers are in a clean area, the problem of dust falling onto the line could not be solved.

An object of the present invention is to provide a cleaning line that can save energy and reduce equipment costs while maintaining the cleanliness required for the production line.

Measures to Solve Problem c] The above purpose is to install an air purification means near the target production line, and to form a space that surrounds the production line and communicates with the clean air outlet of the living air purification means. This can be accomplished by arranging a partition wall so that the partition wall is open, and providing an opening or the like in the partition wall so that an operator can work from outside the partition wall through the opening.

[Effect]

The air purifying device supplies clean air into a partition wall surrounding a production line, purifies the atmosphere of the line, and then discharges the air from a working opening. As a result, the worker always approaches the line from the lower side of Jt, so the risk of dust generated by the worker falling onto the line can be extremely reduced.

Furthermore, since the air purifier is installed only in the target line section, power and equipment costs can be reduced compared to conventional systems.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 24.

A cleaning line in a first embodiment of the present invention will be explained with reference to FIGS. 1 and 2.

In the cleaning line 1 in this embodiment, a clean air supply unit 3 is disposed above the production line 2 as an air purifying device, and the production line 2 is surrounded by a clean air outlet of the clean air supply unit 3. Partition panel 5 as a partition wall
is set up. In this embodiment, the clean metal supply unit 3 is supported on the floor by pillars 4. Clean air is supplied from the clean air supply unit 3 to the space formed by the partition panel 5 and the clean air outlet of the clean air supply unit 3, thereby purifying the atmosphere of the production line. A suitable number of working openings 5a are provided in the partition panel 5 as cutting sections, and workers work on the articles on the manufacturing line 2 from outside the partitioning panel 5 through the working openings 5a. As shown in FIG. 2, the work opening 5a is on the leeward side with respect to the articles on the production line 2, so even if a worker puts his/her hand through this opening, the articles on the line will not come from the worker. Not affected by dust.

A second embodiment of the invention is shown in FIG.

In this embodiment, the clean air supply units 3 are installed discontinuously, and when the level of cleanliness required for the line is not so high, the clean air supply units 3 and clean air are connected as shown in FIG. This is appropriately combined with a ceiling panel unit 26 that does not blow out.

The desired level of cleanliness can be obtained by changing the ratio between the dimension a of the pre-purifying nitrogen gas supply unit 3 and the dimension a of the ceiling envelope unit 26, and by adjusting the total number of circulations.
