Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a carrier and air shower device in various facilities such as factories and distribution facilities requiring clean rooms.

(Prior art) In a variety of facilities such as factories and logistics facilities that require a clean room, when a work that needs to be handled in a clean environment is transported to a clean room with a higher level of cleanliness, adhere to it. An air shower device as a barrier is required to remove dust and other contaminants.

As a conventional air shower device for removing dust and the like adhering to such a work in the automatic transfer path, there is, for example, one shown in FIG. In this air shower device, an air shower chamber b is formed in a horizontal transfer path by a transfer device a such as a conveyor, and automatic doors c are provided on both sides of the air shower chamber b corresponding to the transfer devices a on each side. And a work transfer device e for horizontal transfer is provided in the air shower chamber b, and the work f is used in the air shower chamber when the work device a, e horizontally transfers the same floor. The air shower cleaning is performed by the air shower section g in the b.

(Problems to be Solved by the Invention) Since the conventional air shower device is provided only in the automatic transfer route having different levels of cleanliness on the same floor as described above, it can be installed in a clean room with high construction cost. There are limits in terms of effective use of space, effective removal of dust, etc., and improvement of system capacity.

The present invention aims to improve these points more than ever before.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the transfer and air shower device of the present invention is provided in a transfer chamber configured between upper and lower floors having different levels of cleanliness in a facility. In addition to configuring the work itself by the transfer machine, the transfer chamber corresponds to the transfer machine on each floor and constitutes a work inlet / outlet equipped with an automatic door, and extends vertically inside the transfer chamber. An air shower unit is provided.

(Function) When transferring a work between floors with different levels of cleanliness, especially from a floor with a low level of cleanliness, to a floor with a high level of cleanliness, first transfer the work to the entrance / exit by the carrier of the former floor. The work
After passing through the automatic door that was opened temporarily, it is transferred to the transfer machine in the transfer chamber, and then this transfer machine is moved up and down to operate the air shower section while transferring to the latter floor to perform air shower cleaning. To do. The air shower unit is installed vertically in the transfer chamber, and it irradiates the rising and lowering work with air, so the work is irradiated with air from various angles, and dust etc. are effectively removed. You can Then, when the work arrives at the target floor, the operation of the air shower section is stopped, after which the automatic door is temporarily opened, and the work is transferred from the carrier in the transfer chamber to the carrier on the latter floor. Then, it can be transported to a desired place on this floor. In this way, dust etc. adhering to the work on the floor with a low level of cleanliness is removed by air shower cleaning in the transfer chamber configured between the upper and lower floors,
Cleaner floors with higher cleanliness can be prevented.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIG.

Reference numeral 1 denotes a transfer chamber configured between upper and lower floors 2a and 2b of a facility requiring a clean room, such as a pharmaceutical factory, a semiconductor factory, a physical distribution facility, and the like, and a transfer machine 3 provided in the transfer chamber 1 The work 4 is configured so as to be freely conveyed. Then, the transfer chamber 1 has the floors 2a, 2
Automatic door 6 corresponding to the conveyors 5a and 5b in b.
Work inlets / outlets 7a and 7b provided with a and 6b are configured. The carrier 3 conveys the work 4 between the upper and lower floors 2a and 2b by raising and lowering, and if the work can be transferred between the work machines 4a and 5b on the respective floors 2a and 2b. An appropriate structure may be used, such as a structure in which the conveyor 4 that can be transferred laterally or a moving carriage is supported so as to be able to move up and down. In addition, the carrier 5 on each floor 2a, 2b
The configurations of a and 5b and the number of installations are also appropriate.

An air shower unit 8 is provided vertically in the transfer chamber 1. The air shower unit can be configured by appropriately disposing a fan for air injection, a filter, a slit or a nozzle, and an intake port.

In the above configuration, for example, when the work 4 is transferred from the lower floor 2b having a low level of cleanliness to the floor 2a having a high level of cleanliness, first, the work transferred to the doorway 7b by the carrier 5b. 4 passes through the automatically opened automatic door 6b, is transferred to the carrier 3 in the carrier chamber 1, and then the carrier 3 is raised to carry it to a higher floor. Then, the work 4 is transferred to the carrier 3, and the air shower unit 8 is operated after the automatic door 6b is closed, so that the work 4 is transferred from the lower floor to the higher floor in the transfer chamber 1. Air shower cleaning can be performed.

Since the air shower unit 8 is provided in the vertical transfer chamber 1, it can be partially provided over the entire circumference of the transfer chamber 1 as shown in the example of the drawing, and is also provided vertically. Then, the workpiece 4 that rises (or descends) is irradiated, so that the workpiece 4 is irradiated with the air shower from various angles, and therefore dust and the like can be removed more effectively than the conventional device described above. can do. When the work 4 arrives at the higher floor in this way, the air shower unit 8
Operation is stopped, and then the automatic door 6a is temporarily opened, the work 4 is transferred from the carrier 3 in the carrier chamber 1 to the carrier 5a, and is transferred to a desired place on the floor 2a. You can

The above operation can be easily and automatically controlled by using a microcomputer or the like. Also, in the illustrated example,
Although the number of floors is 2, it is needless to say that the present invention can be applied to the number of floors of 3 or more. Thus, while the work is conveyed between the appropriate floors, the floor is of a low level of cleanliness. In addition, the dust and the like adhering to the work can be removed by the air shower cleaning, and the contamination of the floor with higher cleanliness can be prevented.

(Effects of the Invention) As described above, the present invention, in a facility such as a factory or a logistics facility that requires a clean room, transfers the work vertically while passing through the transfer chamber configured between the upper and lower floors. Since the dust on the work is removed by the air shower cleaning on the floor with a low level of cleanliness, it is possible to easily build a barrier between floors with different levels of cleanliness. Air shower cleaning is performed using the transfer time between floors that has not been used, so the capacity of the system can be greatly expanded, and it is possible to more effectively remove dust etc. compared to the conventional method. It is possible to effectively use the space of the clean room, which has a high construction cost, and so on.
