Description

  The present invention relates to a static eliminator in an automatic warehouse, and in particular, the static eliminator is mounted on a transfer machine of a stacker crane disposed in an automatic warehouse or a manufacturing factory, and the automatic warehouse is used by using the stacker crane. The present invention relates to a static eliminator in an automatic warehouse that automatically performs static eliminator processing.

  Conventionally, in a liquid crystal manufacturing factory, a semiconductor manufacturing factory, etc., parts and products are temporarily stored and transported in a clean room so that impurities do not adhere. In particular, for temporary storage of parts and products, stacker cranes are installed to run along the running path in order to carry parts and products in these factories or in automated warehouses close to these factories. In the transfer machine mounted on the stacker crane, the cassette storing the parts and products is loaded into and unloaded from the loading shelf arranged in the automatic warehouse and along the travel path of the stacker crane. .

By the way, loading shelves are arranged in the automatic warehouse and along the traveling path on which the stacker crane travels. The loading shelves are arranged in a plurality of rows along the normal traveling path and in a plurality of stages in the vertical direction. It is necessary to prevent dust (impurities) from adhering to the parts and products due to the characteristics of the products to be arranged, arranged and manufactured.
However, when a new automatic warehouse is constructed or renewed, the components that make up the loading shelf are subject to static electricity during the manufacture and transportation of the components, or the attachment and assembly of components, and contact with workers. Becomes charged. The electrification of static electricity by the members constituting the loading shelf causes impurities such as dust to adhere to the parts and products stored in the loading shelf. In order to prevent this, at the time of construction or renewal of the automatic warehouse, static electricity removal processing work (static elimination processing) is always performed for each row and each loading shelf before the automatic warehouse is operated.

However, this static electricity removal processing (ionizer treatment) work of the loading shelf is not particularly limited by an operator, but for example, a gun-type static electricity removal device is held by hand, It is a human-powered work to enter and remove electricity.
However, in recent years, the size of the transported goods has increased, and the loading shelves for storing and storing them have also become high-rise and large-sized, and it is difficult and dangerous to perform the static electricity removal processing work of the high-rise large loading shelves manually, There was a problem that it took a long time to work.

  The present invention provides a static eliminator in an automatic warehouse in which the static eliminator in the automatic warehouse is automatically performed using a stacker crane in view of the problems of the conventional static eliminator in the automatic warehouse. The purpose is to do.

  In order to achieve the above object, a static eliminator in an automatic warehouse according to the present invention comprises a static elimination frame that can be attached to and detached from a telescopic arm of a transfer machine mounted on a stacker crane, left and right sides of the static elimination frame, and a telescopic arm extension direction. It consists of a static eliminator attached to the side.

  In this case, the static eliminator attached to the static elimination frame can be a bar type.

  Also, the static eliminator can be attached in two stages, upper and lower, on both the left and right sides of the static elimination frame and the extension arm side.

  In addition, a control program can be incorporated so as to selectively operate the static eliminators attached to the right and left sides of the static elimination frame and the extension arm side.

  According to the static eliminator in an automatic warehouse of the present invention, a static elimination frame that can be attached to and detached from a telescopic arm of a transfer machine mounted on a stacker crane, and static electricity that is attached to both the left and right sides of the static elimination frame and the extension arm side. By constructing it with a remover, it is possible to carry out static electricity removal processing work in an automatic warehouse using a stacker crane, so there is no labor cost as in the past, no dedicated equipment is required, and positioning can be performed accurately. Therefore, highly accurate and uniform static elimination is possible, and even in high-rise and large transfer shelves, static elimination can be performed smoothly in a short time without risk of working at high places. In addition, by programming the transfer shelf charge removal mode in the stacker crane, highly accurate charge removal processing can be performed automatically.

  In addition, by using a bar-type static eliminator attached to the static elimination frame, it is possible to perform uniform static elimination processing on the inner surface of the loading shelf.

  In addition, by attaching the static eliminator to the left and right sides of the static eliminator frame and the extension arm in the upper and lower stages, the transfer machine mounted on the stacker crane can be lowered once along the loading shelf. With the static eliminator attached in two upper and lower stages, the upper and lower ends are not left untouched, and the central part is subjected to static elimination twice, so that highly accurate static elimination processing can be performed easily and quickly.

  In addition, the static eliminator can be used effectively by incorporating a control program to selectively operate the static eliminators attached to the left and right sides of the static elimination frame and the extension arm extension direction. Even with a large loading shelf that accommodates a large cassette that is larger than the width, it is possible to carry out the charge removal process easily.

  Hereinafter, an embodiment of a static eliminating device in an automatic warehouse according to the present invention will be described with reference to the drawings shown in FIGS.

One Example of the static eliminating device in the automatic warehouse of this invention is shown in FIGS.
In the figure, reference numeral 1 denotes an automatic warehouse disposed in a liquid crystal manufacturing factory, a semiconductor manufacturing factory, or the like, or adjacent to these factories. A plurality of loading shelves 10 are arranged and arranged in a plurality of stages in the direction, and a cassette K that stores parts and products is stored and stored in each loading shelf 10.
The individual loading shelves 10 in each row are along the longitudinal direction of the traveling path, and are not particularly limited, but include, for example, cassettes K containing liquid crystal or semiconductor parts. In order to be able to do so, it is formed between the loading shelf columns 11, 11 facing each other with a predetermined interval and on each loading shelf column 11 by protruding the shelf holder 12 at a height position facing each other, and facing at the same position. The shelf receivers 12 and 12 to be mounted are placed so that the bottom end of the cassette K is hooked and loaded.

Accordingly, the interval W1 between the loading shelf columns 11 and 11 arranged along the longitudinal direction of the traveling path R is not particularly limited so that the cassette K to be stored and stored can be stored and stored. The interval W1 between the loading shelf pillars 11 and 11 is determined in accordance with the lateral width so that the cassette K can be smoothly stored in the loading shelf.
Further, in the vertical direction of the shelf supports 12 and 12 provided facing each stage, the interval H between the upper and lower shelf supports is also set in accordance with the size of the cassette K, more specifically, the height of the cassette K. In addition, the interval H between the upper and lower shelf holders is determined to be slightly larger than the height of the cassette K. As a result, the cassette K can be smoothly stored in the loading shelf.

Further, a stacker crane 2 is disposed in the automatic warehouse so as to be able to travel along the traveling path R. The stacker crane 2 is provided with a transfer machine 3 having a telescopic arm having a plurality of telescopic arms. Mount.
The transfer machine 3 is not particularly limited. For example, the transfer machine 3 is configured to be guided by the mast of the stacker crane 2 to move up and down, and includes a plurality of stages of telescopic arms 31, 32, 33. The cassette K is placed on this state-of-the-art telescopic arm 31 so as to be transported and transferred.

Further, the static eliminator A of the present invention uses this stacker crane 2 to be mounted on the most advanced telescopic arm 31 of the transfer machine 3 to perform the static eliminating process in the automatic warehouse.
The static eliminator A includes a static elimination frame 4 that can be attached to and detached from the most advanced telescopic arm 31, and a static eliminator 5 that is attached to both the left and right sides of the static elimination frame 4 and the extension arm extension direction side.

The static elimination frame 4 is mounted on the most advanced telescopic arm 31 so that it can be attached or detached. This is not particularly limited. For example, in the illustrated embodiment, the static elimination frame 4 is parallel to the telescopic arm 31. The two horizontal frames 41 and 41 that are mounted in the vertical direction, the vertical frames 42 and 42 that are integrated at both ends of the two horizontal frames 41 and 41, and the extension of the most advanced telescopic arm 31 The arm 43 is composed of a single horizontal frame 41 arranged on the direction side and projecting horizontally toward the extension direction side of the horizontal frame 41, and the vertical frames 44, 44 attached to the tips of the arms 43, 43.
As a result, the static eliminator A can be set only by placing the two horizontal frames 41, 41 of the static elimination frame 4 on the state-of-the-art telescopic arm 31. If necessary, it is fixed using a fixture (not shown) such as a clamp or a bolt.

The static eliminator 5 attached to the left and right sides of the static elimination frame 4 and the extension direction side of the telescopic arm is disposed so as to span between the vertical frames 42 and 42 facing each other and between the vertical frames 44 and 44. Adopt one. When the static eliminators 5 and 5 are attached to the left and right sides of the static elimination frame 4, the width W 2 of the static eliminator A is determined to be smaller than the interval W 1 between the loading shelf columns 11 and 11.
The bar-type static eliminator 5 is not particularly limited. For example, a clean air barrier static eliminator SJ-V series (manufactured by Keyence) can be used.
This clean air barrier static eliminator is constructed by projecting a plurality of electrode needles (not shown) at regular intervals, and alternately applying a high voltage of “+” and “−” to each electrode needle. The ion current generated by the electrode needle is placed on clean air ejected from the air nozzle 52 formed on the charge removal bar 51, and the charge is eliminated.
As shown in FIG. 1 (a), the static elimination bar 51 has an air nozzle 52 formed on the outer surface and the upper or lower surface of the static elimination bar 51, as shown in FIG. 1 (b). A set of two air nozzles 52 formed on one surface of the bar 51 is arranged in a set so that clean air can be jetted onto two surfaces, a side surface (back surface) and an upper surface or a lower surface. Thereby, the process of 2 surfaces, the side of a loading shelf, and a top | upper surface, or a bottom face can be performed simultaneously by one static elimination process.

Further, the bar type static eliminator 5 can be arranged so as to span between the vertical frames 42 and 42 and 44 and 44, respectively. However, as shown in FIG. Can be arranged so as to span two by two.
As a result, it is possible to expand the range that can be neutralized at a time while preventing the interference of the structural members, and the upper and lower ends are not left untouched. In addition, it is possible to perform highly accurate static elimination processing quickly.

  In addition, the static eliminators 5, 5, and 5 attached in three directions on the right and left sides of the static elimination frame and in the extension arm extension direction side (advance side) are either one of the right side, the left side, or the advance side, or two or three. A control program can be incorporated to selectively operate. As a result, even if the width W2 of the static eliminator A is considerably smaller than the interval W1 between the loading shelf columns 11 and 11, the static eliminator A is lowered along the one loading shelf column 11 and then the static electricity is removed. By removing the removing device A closer to the loading shelf column 11 side on the other side and again descending, it is possible to easily perform the charge removal process even on the loading shelf that accommodates the large cassette K having the large interval W1.

Next, the operation of the static eliminator in the automatic warehouse of the present invention will be described.
The construction or renewal of the automatic warehouse is completed, and before the cassette K is stored in the automatic warehouse, the static electricity removal (static elimination) of the loading shelf is performed using a stacker crane disposed in the warehouse. This is because the static eliminator A is placed on the most advanced telescopic arm 31 of the transfer machine mounted on the stacker crane, and a predetermined position of the telescopic arm is secured by a fixture such as a clamp or a bolt as necessary. Although not particularly limited, for example, the static electricity removing device A is fixed so that the central portion thereof coincides with the central portion of the telescopic arm 31. And, when removing the load from the load shelf, the charge removal process is performed from the top load shelf. This is to remove it.

After setting the static eliminator A, the transfer machine is moved up and down to a predetermined loading shelf position to extend the telescopic arm, and the most advanced telescopic arm 31 is inserted into the uppermost loading shelf. Thereby, the static eliminating device A attached to the telescopic arm 31 is also inserted into the loading shelf. In this case, the static eliminator A is positioned at the upper position in the uppermost loading shelf, and the distance between the loading shelf column or the side wall disposed along the loading shelf column and the static eliminator 5 is the static eliminator. It is assumed that the ion generated in 5 is set to be within the static elimination possible range.
Next, when all the static eliminators 5 are actuated and the transfer machine is lowered while generating ions from each electrode needle, the loading shelf columns facing the left and right or the side walls disposed along the loading shelf columns, The back wall disposed in the inner back portion is simultaneously discharged from the upper position along the lower position. Garbage removed by this charge removal falls downward, but some of it may adhere to the lower loading shelf or the like.
When the static eliminator A descends in the loading shelf due to this charge removal processing, the static eliminator 5 is required if the length of the bar-shaped static eliminator 5 is equal to the depth and width of the loading shelf. However, if the length of the static eliminator 5 is shorter than the depth and width of the loading shelf, the static eliminator A can be moved forward and backward. What is necessary is just to make it descend | fall while moving to a horizontal direction.

When the charge removal of the uppermost loading shelf is completed in this way, the process of removing electricity from the second loading shelf from the top is started. In this case, after the telescopic arm is contracted at one end, the transfer machine 3 is lowered to the position of the second stage loading shelf, and then the telescopic arm is extended to perform the static elimination process in the same manner. However, if the static eliminator 5 of the static eliminator A passes through the space between the left and right shelf holders without contacting any of the shelf holders, the expansion and contraction of the telescopic arm can be omitted. Therefore, it is possible to perform the charge removal process from the uppermost loading shelf to the second stage.
By repeating this operation, the charge removal process up to the lowest loading shelf can be completed.

  In the loading shelf for storing and storing a large cassette K, the inner width of the loading shelf is larger than the lateral width of the cassette K, and the static elimination process by the ions generated by the static eliminator 5 is lowered once along the loading shelf. If uniform processing cannot be performed only by operation, either one of the static electricity removers 5 facing left and right is placed on one of the loading shelf columns facing the loading shelf column or the side wall disposed along the loading shelf columns. Then, the static elimination device A is raised in the same loading shelf after the static elimination treatment is performed by setting the ionizing range within the range of ions and lowering it along the loading shelf column or side wall. After moving the transfer machine laterally so that the removing device A follows the opposite loading shelf column or the side wall, it is possible to perform the charge removal process on both the left and right sides of the loading shelf by lowering again.

When performing static elimination processing using this stacker crane, the static elimination processing is automatically performed using the stacker crane by programming not only the transfer mode by the stacker crane but also the static elimination processing mode. be able to.
In addition, by attaching the static eliminator 5 to the left and right sides of the static eliminator frame and the extending direction of the extendable arm respectively, the static eliminator A can be lowered once, and the column of the loading shelf opposite to the static eliminator A can be lowered. Alternatively, the neutralization of the wall surface can be performed more reliably and accurately.

  As mentioned above, although the static electricity removal apparatus in the automatic warehouse of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, In the range which does not deviate from the meaning, the The configuration can be changed.

  The static eliminator in the automatic warehouse of the present invention has a characteristic that the static eliminator is automatically performed using the stacker crane by mounting the static eliminator on the transfer machine mounted on the stacker crane. Therefore, it can be suitably used for static elimination in an automatic warehouse equipped with a stacker crane, and can also be used for static elimination in a clean room of a manufacturing plant, for example.
