Abstract

PURPOSE:To enable an efficient removal of dusts to be performed by a method wherein an air shower cleaning is carried out within a transfer chamber when a workpiece is transferred vertically through the transfer chamber arranged between upper and lower floors, the air shower cleaning is performed within the transfer chamber. CONSTITUTION:When a workpiece 4 is transferred from a floor 2b to a floor 2a, the workpiece 4 transferred to an inlet or outlet opening 7b by a transfer device 5b is passed through an automatic door 6b, moved onto a transfer device 3 within a transfer chamber 1 and the transfer deice 3 is lifted up to transfer the workpiece to a higher floor. After the workpiece is moved onto the transfer device 3 within the transfer chamber 1, an air shower part 8 is operated to cause the workpiece 4 to be transferred from a lower floor to an upper floor and the air shower cleaning is carried out within the transfer chamber 1. In this way, since the air shower part 8 is arranged with the vertical transfer chamber 1, it may be arranged at an entire circumference within the transfer chamber 1. The workpiece arranged vertically and being lifted up is radiated, so that a more efficient removal of dusts can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conveyance/air shower device used in factories, logistics facilities, etc. that require clean rooms.

(Prior art and its problems) A conventional air shower device for removing dust, etc. attached to a workpiece that requires handling in a clean environment by placing it on the automatic transport path of the workpiece, for example, 2
As shown in the figure, an air shower room is constructed in the horizontal transport path by a transporter a such as a conveyor, and automatic doors C are installed on both sides of the air shower room, corresponding to the transporter a on each side. In addition to configuring a workpiece entrance d with a workpiece entrance d, a conveyor @e for horizontal conveyance is also provided in the air shower room, and when the workpiece f is horizontally conveyed on the same floor by the conveyors a and e, The structure is such that air shower cleaning is performed by the air shower section q during the cleaning process.

Conventional air shower devices are installed only on the automatic conveyance path on the same floor, so
There were limitations in terms of effective use of clean room space, which is expensive to construct, effective removal of dust, etc., and improvement of system capacity.

The present invention aims to improve these points over the conventional ones, and will be described in detail below based on drawings corresponding to embodiments.

(Means for solving the problem) Reference numeral 1 refers to the upper and lower floors 28 of facilities that require clean rooms, such as pharmaceutical factories, semiconductor factories, etc., and logistics facilities.
2b shows a transfer chamber configured between the transfer chamber 1 and the transfer chamber 1, in which a workpiece 4 is configured to be freely transferred by a transfer machine 3. The transfer chamber 1 has automatic doors 6a, 6b corresponding to the transfer machines 5a, 5b on each floor 2a, 2b.
The workpiece entry/exit lowers a and 7b are configured. The conveyor 3 moves the workpiece 4 to the upper and lower floors 2a by raising and lowering it.
, 2'o, and each floor-2a,
As long as the workpiece 4 can be transferred between the conveyors 5a and 5b in the conveyor 2b, any suitable structure may be used, such as a conveyor that can move the workpiece 4 laterally or a structure that allows the moving cart to be moved up and down. Also, the conveyor 5a on each floor 2a, 2b,
The configuration and number of units 5b installed are also appropriate. Therefore, the present invention is characterized in that an air shower section 8 is provided vertically within the transfer chamber 1. The air shower section 8 is constructed by appropriately arranging an air injection fan, filter, slit or nozzle, and an intake port.

[Effect]

In the above configuration, when transporting the workpiece 4 from the lower floor 2b to the higher floor 2a, for example, the workpiece 4 is first transported to the entrance/exit lower b by the transporter 5b.
Pass through the automatic door 6b that is temporarily opened □ and enter the transfer room 1.
The material is then transferred to the transport machine 3 inside the building, and the transport machine 3 is raised and transported to a higher floor.

After the workpiece 4 is transferred to the transport chamber I3 and the door 6b is closed, the air shower unit 8 is operated, so that an air shower is generated in the transport chamber 1 while the workpiece 4 is transported from the lower floor to the upper floor. Can be washed. In the present invention, since the air shower section 8 is provided inside the transfer chamber 1 in the vertical direction, it can be provided partially over the entire circumference inside the transfer chamber 1 as shown in the illustrated example, and can also be installed over the entire circumference of the transfer chamber 1 in the vertical direction. Since the workpiece 4 is irradiated with the workpiece 4 that is rising, the air shower is irradiated onto the workpiece 4 from various angles. Therefore, compared to the conventional 5A installation mentioned above, dust etc. are removed more effectively. can do.

When the work 4 reaches the upper floor in this way, the operation of the air shower section 8 is stopped, and then the automatic door 6a is temporarily opened to transfer the work 4 from the transport machine 3 to the transport machine 5a. 615a, 5th floor floor-2a
can be transported to the desired location. Note that the above operations can be easily automatically controlled using a microcomputer or the like.

In addition, in the illustrated example, the number of floors is 2, but 3
It goes without saying that the present invention can be applied to the above number of floors, and in this way, when the workpiece 4 is transferred between appropriate floors, it is possible to wash the workpiece 4 by one shower.

〔Effect of the invention〕

As described above, in facilities such as factories and logistics facilities that require a clean room, when a workpiece is transported vertically through a transport chamber constructed between upper and lower floors, an air shower is installed in the transport chamber. Since it is configured to perform cleaning, it is possible to easily construct a barrier between floors with different levels of cleanliness. (2) Since air shower cleaning is performed using the transport time between floors, which was not used in the past, the capacity of the system can be greatly increased. ■Compared to conventional methods, it is possible to remove dust more effectively. ■It has special effects such as being able to effectively utilize the space of a clean room, which is expensive to construct.
