Description

The present invention relates to a storage for storing and / or transporting stored materials in a factory or the like while maintaining cleanliness.

As shown in FIGS. 18 and 19, the conventional storage 2000 of this type has a fan 2004 and a filter 2006 in a roof portion 2002, and sends clean air CA obtained by filtering outside air A to a lower storage room 2008. There is. The storage room 2008 is partitioned by a plurality of horizontal shelf boards 2010 so that the storage items W can be stored in multiple stages.
A large number of through holes 2012 are bored in the shelf plate 2010 of each stage, and the clean air CA used for cleaning the stored matter W is further sent to the lower stage. The foreign matter D such as dust generated from the stored matter W and the shelf board 2010 at the upper stage flows to the lower stage and adheres to the stored matter W.
Therefore, as shown in FIG. 21, the foreign matter adhesion phenomenon occurs more frequently in the lower row, and the cleanliness of the stored matter W is lowered.

In addition, as shown in FIG. 20, when the door 2016 provided in the opening 2014 is opened to take out and put out the stored item W, the uppermost stage is a corner, and in the lower stage where the static pressure of the clean wind CA is low. The outside air invades and the stored matter W becomes dirty.
Then, as shown in FIG. 21, since the used clean air CA is exhausted from the lowermost level of the storage room 2008 to the floor, soaking dust on the floor and soaking the inside of the factory . This causes clogging of the filter 2006 on the roof 2002, which makes maintenance of the filter 2006 difficult.

As shown in FIG. 22 and FIG. 23, when the static eliminator 2020 is attached to the ceiling part 2018 at the top of the storage room 2008, the ion PN is absorbed by the shelf board 2010 and can not pass through the through hole 2012. The static electricity can not be removed after the second stage.

As shown in FIGS. 24 and 25, when the static eliminator 2020 is mounted on the back side wall 2022 separated from the opening 2014 of the storage room 2008, the static eliminator 2020 is directed by the downward clean air CA coming out of the filter 2006. The ions PN generated from the source flow downward, and the static electricity of the stored matter W near the opening 2014 can not be removed.

As shown in FIG. 26, since the filter 2006 is installed on the roof portion 2002, the foreign matter D dropped from the filter 2006 may enter the storage room 2008 and contaminate the storage room 2008 when the filter 2006 is maintained. There is.

As shown in FIG. 27, when moving the storage 2000 with the storage item W stored in the storage room 2008, the storage 2000 can not normally be grounded (earth), but movement of the storage 2000 The friction between the wheels 2024 and the floor 2026 generates static electricity, which accumulates in the storage. FIG. 28 shows the characteristic that the static electricity accumulated in the storage 2000 increases with time.

Thus, the conventional storage has many basic problems, and conventionally there was no means to solve this.

For this reason, conventionally, even if the stored matter is stored in the storage, it has been considered that the adhesion of the foreign matter can not be completely prevented, and it is considered that the matter is almost calm.

  The present invention is directed to cleaning stored goods during storage.

  Next, a preferred embodiment of a storage according to the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, the storage 1000 includes a rectangular parallelepiped storage room 1008 having an opening 1014 on one side, and the inside of the storage room 1008 is provided to the multistage shelf room 1048 by a horizontal shelf plate 1010. A fan 1004, an upstream filter 1006, and a filter 1007 are disposed at the top, separated.
An open door 1016 is attached to the storage chamber 1008 and can open and close the opening 1014.

A horizontal support plate (partition plate) 1040 is attached to the top of the storage chamber 1008, and the fan 1004 is attached and fixed on the support plate 1040. The upstream filter 1006 is disposed upstream of the fan 1004, and the filter 1007 is disposed downstream of the fan 1004, and filters the air blown by the fan 1004 to produce clean air CA. It is also possible to omit the upstream filter 1006 and filter the air only by the filter 1007. A space on the upstream side of the fan 1004 in the space above the partition plate 1040 is referred to as a fan upstream space 1049.

A side wall flow path 1044 along the side wall is formed on the upstream side of each shelf chamber 1048, and a side wall flow path 1050 along the side wall is formed on the downstream side. Air is allowed to flow into the flow path 1044 from the inlet 1046, and the air is raised from the flow path 1044 through the respective racks 1048 to rise in the flow path 1050 and return to the fan upstream space 1049.
Note that at least one shelf chamber 1048 is provided, and a channel having a constant rectangular cross section is formed between the channel 1044 and the channel 1050.

The clean air CA filtered by the filter 1007 flows into the rack room 1048 on each shelf 1010 while flowing down the flow path inlet 1046 and is stored in the shelf 1010 while flowing toward the opening 1014. Keep W clean.
In addition, it is preferable that a perforated plate 1020 having a large number of holes be provided between each shelf 1048 and the flow path 1044. As a result, the flow rate of air flowing into each shelf 1048 is equalized.

A static eliminator 1030 is disposed upstream of each shelf room 1048 to ionize the clean air CA flowing into the shelf room 1048. The ionized clean air CA removes static electricity accumulated in the stored matter W stored in the rack room 1048.

The clean air CA passes through the rack room 1048 and then reaches the opening 1014, ascends the flow path 1050 in the door 1016 and flows into the fan upstream space 1049 on the support plate 1040. That is, the fan 1004 circulates air so as to pass through the flow path inlet 1046, the flow path 1044, the rack room 1048, and the flow path 1050 sequentially, and return to the fan 1004, and is contaminated during storage of the storage W Clean the air repeatedly to keep it clean.
The door 1016 is in the form of a cavity constituted by a perforated plate 1020 having a large number of holes on the side of the opening 1014, and the inside of this cavity is a flow path 1050. The hole of the holed plate 1020 has a large diameter at a position in contact with the fan upstream space 1049, and the pressure loss is suppressed at the lowest pressure position immediately before flowing into the fan upstream space 1049. This makes the circulation of the clean wind CA smooth.
The support plate 1040 separates the rack room 1048 from the upper fan upstream space 1049, the fan 1004, and the filters 1006 and 1007, and cleans the clean air CA smoothly through the flow path inlet 1046, the flow path 1044, and the rack room 1048. Function as a partition plate for guiding to the channel 1050.

A roof portion 1002 of the storage room 1008 is provided with an outside air inlet 1028 opened to the outside air A. Outside air A enters the fan upstream space 1049 from the outside air inlet 1028 of 1002.
Therefore, as shown in FIG. 4, the fan upstream space 1049 is at an atmospheric pressure equal to the atmospheric pressure.
When the roof portion 1002 is provided with the outside air inlet 1028, the air pressure of the flow path inlet 1046, the flow path 1044, the rack room 1048, and the flow path 1050 from the downstream of the fan 1004 becomes positive with respect to the atmospheric pressure. Will not intrude.

  The door 1016 is opened and closed when the stored item W is taken out, but since the clean air CA flows from the back surface 1042 toward the opening 1014 in the rack room 1048, the opening 1014 is opened when the door 1016 is opened. The outside air A does not flow into the rack room 1048 from there. Therefore, even when the door 1016 is opened, the stored product W does not touch the unclean outside air A, and the cleanliness is maintained.

  Furthermore, the storage room 1008 is provided with wheels 1024 for traveling and transporting the storage 1000, and can move smoothly on the floor 1026.

Prevent them from invading
Most of the air in the storage room 1008 continues to circulate inside, so the frequency at which the filters 1006 and 1007 filter out unclean outside air is low, and the filters 1006 and 1007 require almost no maintenance. Further, even when the door 1016 is opened, air is not discharged from the storage room 1008 toward the floor, so that, for example, in the factory, dust on the floor is not thrown up, so the factory environment is not polluted.
In the first embodiment, the multistage shelf room 1048 is provided in the storage room 1008, but the shelf room 1048 may be one stage.

The discharge electrodes 1066 and 1068 are connected to the anode of the rectifier 1076 and the cathode of the rectifier 1078, respectively.
The rectifiers 1076 and 1078 pressurize the voltage of the storage 1000, and supply them to the discharge electrodes 1066 and 1068, respectively, and discharge positive ions and negative ions by corona discharge at the discharge electrodes 1066 and 1068, respectively. Thereby, the static electricity of the storage 1000 is removed.
The rectifiers 1076 and 1078 and the discharge electrodes 1066 and 1068 are accommodated in the insulating case 1070, and the discharge electrodes 1066 and 1068 discharge the ions PN from the openings 1072 and 1074 formed in the insulating case 1070 to the outside.

FIG. 17 is a graph showing the relationship between the charged state of the vehicle body of FIG. 15 and the amount of generated (discharged) ions from the wireless grounding device 1032, where the amount of positive ions released increases as the charge is more strongly positive, It can be seen that the more strongly the negative side is charged, the more the amount of anions released.

By installing the wireless grounding device 1032, charging of the storage 1000 can be prevented even when the storage 1000 can not be grounded. In this case, the wireless grounding device 1032 is driven by a battery (not shown).
