Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a self-rolling curtain for channel attachment.

[Prior art] Conventionally, as shown in Fig. 4, clean room R
In some cases, a special clean room S with an even higher ultra-cleanliness level is set up in a room surrounding the production equipment, etc.
Automatically roll up curtains 11 on the four circumferences of the ceiling T
A plurality of vinyl curtains 14 are installed so that the vinyl curtain 14 hangs down. In the ceiling T, channel cells C supported by hanging bolts B suspended from beams (not shown) are stretched over the entire surface in a cross shape to form a rectangular section k. Ultra-high performance HEPA with a planar shape of almost equal size
A side plate Fs that holds the filter F from all four sides is placed on the channel cell C, and a special sealing liquid E (for example, a silicone shielding agent) is applied to the recessed inner channel of the channel cell C, The special clean room S and the back of the ceiling T are completely airtight. (See Fig. 2) To install the automatic winding curtain 11, for example, as shown in Fig. 5, hang bolts B vertically suspended from a plurality of mounting span plates P installed on both beams H. The automatic roll-up curtain 11 is crimped to the ceiling T by passing through the ceiling T and facing into the clean room R, and tightening the L-shaped mounting brackets 12k attached to the front and upper rear surfaces of the storage case 12 of the automatic roll-up curtain 11. Fixed.

In addition, as another conventional example, as shown in FIG. 6, a horizontal frame Wy is mounted on the top surface of a pair of support frames Ws, which are provided with guide rails G for guiding the weight 14w of the curtain 14 on the inner surface. In some cases, a lever-shaped outer mounting frame W is erected so as to reach the ceiling T from the floor Y, and the storage case 12 is attached to the lower surface of the horizontal frame Wy.

[Problem that the invention attempts to solve]

However, special clean rooms require three changes such as changing the model or rearranging the production equipment installed inside.
It is customary to be carried out every ~6 months, and each time,
It is necessary to change the plan shape, size, or location of the special clean room, but in the former case of the conventional example, the installation of hanging means in the ceiling is extremely troublesome, time-consuming, and time-consuming. However, in the latter case, the outer frame for mounting is large, requiring manpower to move it, and the manufacturing cost is high.
This has the disadvantage that consideration must be given to the storage location of items that are not in use.

[Means for solving problems]

In view of the above-mentioned circumstances, the present invention focuses on utilizing the existing channel cell stretched across the ceiling of the clean room, and a rotating drum rotated by a motor pulley is installed inside, and a weight is attached to the drum. A storage case is created that is equipped with electric parts for a motor pulley to wrap the curtain around the lower side and perform drooping and winding operations of the curtain, and can be directly attached and detached to the channel cell using a latching fitting. The present invention aims to solve these problems by providing an automatic winding curtain.

[Effect]

Therefore, attachment and detachment of the automatic winding curtain does not require any tools other than a stepladder, and a special clean room can be created extremely quickly and easily.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

First, I will explain the configuration.

This automatic winding curtain 1 is mainly composed of a storage case 2, a rotating drum 3, a curtain 4, and an electric component 5, as shown in a partially sectional front view shown in FIG.

As shown in the horizontal cross-sectional view in FIG.
A longitudinal groove 2m for storing an electric cord is formed in c, and a curtain 4 is formed on one side of the bottom plate 2t.
A slit 2s is bored through it. Two sets of snap-lock type latching fittings 2k are provided at required locations on the upper portions of the front surface 2f and the rear surface 2b, respectively. If the curtain 4 is wide, several sets of hooks 2k are provided depending on the length of the storage case 2.

The rotary drum 3 is rotatably attached to a shaft 3s fixed to a pair of left and right support fittings 2l fixed to the lower surface of the groove bottom plate 2mt of the groove 2m of the case 2, and has a built-in multi-stage reduction type motor pulley. 3m are integrally connected.

The curtain 4 is a transparent vinyl curtain that has been subjected to antistatic treatment, and a long weight 4w is attached along the entire length of the lower side, while the upper side is fixed to the rotating drum 3, and the movement of the motor pulley 3m is fixed to the upper side. It is wrapped around the rotating drum 3 and raised, or it hangs down together with the weight of the weight 4w to partition the clean room R.

Although not shown, the electrical components 5 are suspended in the clean room R, and include a cab tire equipped with a push button switch box for controlling the rotation of the rotating drum 3, and a motor pulley 3 from a power source (not shown).
An electric cord 5c is housed in the groove 2m of the main body 2h and equipped with a plug 5p in order to conduct power to the main body 2h.
and a limit switch 5 that comes into contact with the weight 4w to stop the winding of the curtain 4 around the rotating drum 3.
It is with l.

Next, a method of using the storage case 2, which is a feature of the present invention, will be described.

Automatic winding curtain 1 item channel cell C
To install it, connect the power cord passing through the bottom plate Ct to the required location of the channel cell C, and connect the plug 5p of the electric cord 5c to the socket 5s attached to the bottom surface of the bottom plate Ct.
Raise the handle 2kh of the latch 2k, hook the tip 2kk extending upward to the upper edge Ce of the channel cell C, and then pull down the handle 2kh downwards for each latch 2k in sequence. Then, the top surface 2c of the main body 2h is connected to the bottom plate of the channel cell C.
Attach storage case 2 to the Ct.

Note that for removal, the above operations may be performed in reverse order. (See Figures 2 and 3.) When a plurality of automatic winding curtains 1 are installed in series, an intermediate socket (not shown) having a plurality of socket parts is connected to the socket 5s, and other automatic winding curtains are connected to each other. The electric cord 5c is passed through the groove 2m of the curtain 1 as a guide groove, and the plug 5p thereof is connected to the intermediate socket, and then the automatic winding curtain 1 is attached to the channel cell C in a row.

Relocation of the automatic winding curtain 1 can be carried out quickly and easily since it can be easily removed and attached using the snap-lock type mounting fittings 2k.

In addition, the gap between the curtains 4 which are in a continuous hanging state can be created by installing a removable guide support (not shown) between the floor surface and the continuous part of the automatic winding curtain 1, or by Adjacent curtains 4 may be connected by a removable adhesive tape.

[Effect of idea]

As explained above, since the present invention has the above-mentioned configuration, the automatic winding curtain can be attached and detached from the channel cell extremely quickly and easily.
There is an advantage that a special clean room having an ultra-cleanliness level in a desired area can be quickly and easily formed without using any tools. Furthermore, the structure is simple, and no auxiliary members are required for attachment, making it extremely inexpensive.
