Description

  The present invention comprises an article storage section in a plurality of upper and lower stages, and can be moved up and down along a storage shelf installed in an air-conditioning target space that is partitioned from the outside and adjusted to a predetermined air-conditioning state, and a lifting mast. An article that includes an elevating part for supporting an article having a width greater than that of the elevating mast, and that travels between the inside and the outside of the air-conditioning target space through an opening for passing a conveyance vehicle that is opened in a side wall part of the air-conditioning target space. The present invention relates to an article storage facility provided with a transport vehicle.

  As the article storage facility, for example, an aging warehouse in which the inside of the air-conditioning target space is maintained at a temperature higher than normal temperature and the articles are stored in the article storage unit of the storage shelf, or the air-conditioning target space is set at a temperature higher than normal temperature. There are low-temperature warehouses and the like that store articles at a low temperature while maintaining a low temperature.

  The air-conditioning target space is partitioned from the outside in order to maintain the air-conditioning state, but the side wall of the air-conditioning target space is provided with a transport vehicle passage opening, and the article transport vehicle is passed through the transport vehicle passage opening. By traveling over the inside and outside of the air-conditioning target space, the article can be carried in from the outside and the article can be carried out to the outside.

  As described above, in the article storage facility, the article transport vehicle can travel between the inside and outside of the air conditioning target space while maintaining the air conditioning state of the air conditioning target space as much as possible.

  In order to suppress the flow of air into and out of the air-conditioning target space as much as possible through the opening for passing the conveyance vehicle, conventionally, the opening and closing that can be opened / closed to open and close the entire surface of the opening for passing the conveyance vehicle is possible. Some doors are provided (for example, refer to Patent Document 1).

JP 2000-142913 (paragraphs “0022” and “FIG. 1”)

  By the way, if the number of the upper and lower stages of the article storage unit in the storage shelf is increased in order to obtain an article storage facility having a high storage capacity, the article transport vehicle can be moved up and down to a height corresponding to the article storage unit at a higher position. It is necessary to configure the lifting mast with a high height, and as a result, the height of the opening for passing the transport vehicle is also increased.

  However, since the conventional article storage facility is provided with an open / close door that opens and closes the entire surface of the transport vehicle passage opening, the height of the lifting mast of the article transport vehicle is increased. If the height of the opening for passing the transport vehicle is also increased accordingly, the entire height of the opening for passing the transport vehicle is closed by the open / close door, and air passes through the opening for passing the transport vehicle. Since it will suppress flowing inside and outside, it is necessary to enlarge an opening-and-closing door.

  As a result, the weight of the open / close door also increases, making it difficult to open and close the open / close door, increasing the time required for the open / close operation, causing a waiting time until the open / close operation is completed, and reducing the operation efficiency of the article transport vehicle. Inconvenience, and the operating mechanism for opening and closing the door is increased in size and robustness, which is disadvantageous in terms of cost and installation conditions.

  Furthermore, when the article transport vehicle is passed through the transport vehicle passage opening, the entire surface of the transport vehicle passage opening is opened, so that air easily flows into and out of the air-conditioning target space. The adverse effect is severe. This problem becomes more prominent as the area of the opening for passing the transport vehicle is larger.

  The present invention has been made in view of the above circumstances, and its purpose is to pass a transport vehicle without causing inconveniences as much as possible even when the height of a storage shelf is increased to improve the storage capacity. The object of the present invention is to provide an article storage facility capable of suppressing air from flowing into and out of the air-conditioning target space through the opening.

In order to achieve this object, an article storage facility according to the present invention is provided in an air-conditioning target space that is provided with an article storage section in a plurality of upper and lower stages and that is partitioned from the outside and adjusted to a predetermined air-conditioning state. Air-conditioning through an opening for passing a transport vehicle, which is provided with a storage shelf and an elevating part for supporting an article that is movable up and down along the elevating mast and has a larger width than the elevating mast. An article transport vehicle that travels between the inside and the outside of the target space is provided, and the first characteristic configuration is that the transport vehicle passage opening is as viewed in the travel direction of the article transport vehicle. A part of the vertical direction is formed as a wide part through which the elevating part can pass, and the remaining part is formed as a narrow part narrower than the wide part. To flow into Suppressing air through-flow suppressing means is provided, said air through-flow suppressing means, with the wide portion opening and closing freely opening and closing door in a state of open closing a state, air in the width direction in the narrow portion It is in the point comprised from the air flow means to flow through .

  That is, the conveyance vehicle passage opening opened in the side wall portion in the air-conditioning target space has a portion in the vertical direction as a wide portion through which the elevating portion can pass, as viewed in the traveling direction of the article conveyance vehicle, and the remaining portion. Is formed as a narrow part narrower than its wide part, so that the width of the narrow part is as close as possible to the width of the relatively narrow part of the article transport vehicle (for example, the lifting mast part) and passes through the transport vehicle. The opening area of the opening for passing the conveyance vehicle can be reduced by partially narrowing the lateral width of the opening for use. By reducing the opening area, it becomes difficult for air to flow into and out of the air-conditioning target space through the opening for passing the transport vehicle.

  And the elevating part has a larger width than the elevating mast, but the elevating part corresponds to the height of the wide part because the elevating part can be freely passed through the opening for passing the carriage. When the article transport vehicle travels between the inside and outside of the air-conditioning target space through the transport vehicle passing opening by traveling in a state matched to the lift position, the lift section having a larger lateral width than the lift mast is the wide section. The article transport vehicle can be made to travel so as to pass. Therefore, the elevating part which is relatively wide does not interfere with the side wall part and does not hinder the traveling of the article transport vehicle.

  In this way, by forming a narrow portion in the transport vehicle passage opening and reducing the opening area of the transport vehicle passage opening, air is less likely to flow into and out of the air-conditioning target space through the transport vehicle passage opening. By forming a wide portion that allows the elevating part to pass through the opening for passing the transport vehicle, the article transport vehicle can travel inside and outside the air-conditioning target space.

  And when forming the conveyance vehicle passage opening so as to correspond to the article conveyance vehicle provided with a long lifting mast that can deliver the article to and from the article storage unit at a high position, the height direction of the wide portion This can be dealt with by increasing the length of the narrow portion in the height direction without changing the length of the narrow portion.

  In addition, since air flow suppression means is provided, air is prevented from flowing into and out of the air-conditioning target space through the transport vehicle passage opening, but the smaller the lateral width of the transport vehicle passage opening is, the smaller the width is. Since air can easily be prevented from flowing into and out of the air-conditioning space through the transport vehicle passage opening, the configuration of the air flow restraint means is simplified for the portion corresponding to the narrow portion of the transport vehicle passage opening. Can be.

  Therefore, when forming the transport vehicle passing opening so as to correspond to an article transport vehicle having a long lifting mast, the air flow suppressing means is provided so that the portion corresponding to the narrow portion is elongated in the height direction. What is necessary is just to comprise, and a simple location of a structure should just be comprised long in a height direction.

  That is, even when the storage shelves are configured with a high height in order to improve the storage capacity of the storage facility, inconveniences are less likely to occur because the air flow suppressing means only needs to be configured with a simple portion extending in the height direction.

  As described above, according to the first characteristic configuration of the present invention, even when the storage shelf is increased in height and the storage capacity is improved, the air can be air-conditioned through the opening for passing the transport vehicle without causing inconvenience as much as possible. It came to obtain the article | item storage equipment which can suppress flowing through inside and outside.

Further, according to the first characteristic configuration of the present invention, the open / close door is configured to be freely openable / closable in a state where the wide portion is opened and in a closed state. Since only a small size is required, the door can be configured with a small door that is easier to handle than a size that closes the entire opening for passing the transport vehicle.

  If the opening / closing door is opened to open the wide part, the lifting / lowering part of the article transport vehicle can pass, and the opening / closing door is closed to close the wide part. Since the wide portion of the opening is shielded by the door which is a structure, it is possible to effectively suppress air from flowing into and out of the air-conditioning target space in the wide portion.

  The air flow means allows air to flow in and out of the air-conditioning target space in the narrow portion by causing air that does not hinder the travel of the article transport vehicle in the width direction in the narrow portion. Therefore, the narrow portion is in a state in which the article transport vehicle can pass while the air is suppressed from flowing into and out of the air conditioning target space.

That is, according to the first characteristic configuration of the present invention, the air flow in the wide portion can be effectively suppressed, and the air conditioning is performed through the opening for passing the transport vehicle only by an easy operation of opening and closing the openable door. It can be set as the state which an article conveyance vehicle can drive over the inside and the exterior of object space.

According to a second characteristic configuration of the article storage facility according to the present invention, in the first characteristic configuration, the wide portion is positioned below the opening for passing the conveyance vehicle, and controls the operation of the article conveyance vehicle and the door. The article transport vehicle has a control means such that the article transport vehicle passes through the opening for passing the transport vehicle in a state where the lift unit is located at the lower limit of the lift and the open / close door opens the wide portion. And it is in the point comprised so that the action | operation of the said door may be controlled.

  That is, since the wide portion is located below the opening for passing the transport vehicle, the door can be installed near the floor surface, so that the door can be easily installed.

  In addition, the control means controls the operation of the article transport vehicle and the opening / closing door, so that the article transporting vehicle passes through the transport vehicle in a state where the lifting / lowering portion is positioned at the lower limit of lifting and the opening / closing door opens the wide portion. Because the product passes through the opening, even if the operator does not need to manually perform the opening / closing operation of the opening / closing door and the lifting / lowering operation of the lifting / lowering section by manual control, It can travel between the inside and outside of the target space, and is easy to use.

Thus, according to the 2nd characteristic structure of this invention, it came to obtain the article storage equipment which was easy to install an opening-and-closing door and was easy to use.

According to a third characteristic configuration of the article storage facility according to the present invention, in the second characteristic configuration, when the control means does not perform the work of taking in and out the article with respect to the storage shelf by the article transport vehicle, The article transport vehicle and the opening / closing door are operated so that the article transport vehicle stands by outside the air-conditioning target space with the wide portion closed and the lift unit positioned at the lower limit position. In that it is configured to control.

  That is, since the inside of the air conditioning target space is adjusted to a predetermined air conditioning state, for example, when the inside of the air conditioning target space is adjusted to a high temperature (for example, 60 degrees Celsius) higher than normal temperature. If the article transport vehicle stays in the air-conditioning target space for a long time, there is a risk that an electronic component such as a control device provided in the article transport vehicle or a mechanical part such as a drive mechanism may break down.

According to the third characteristic configuration of the present invention, when the article transporting operation is not performed with respect to the storage shelf by the article transporting vehicle, the above-described inconvenience can be generated by waiting the article transporting vehicle outside the air-conditioning target space. It becomes possible to prevent.

  In addition, when the article transporting operation is not performed on the storage shelf by the article transport vehicle, the wide door is provided while the door is in the closed state so that the article can be removed from the storage shelf. In this case, the air is reliably prevented from flowing into and out of the air conditioning target space, and the air conditioning state inside the air conditioning target space is easily maintained.

  Further, when the article transport vehicle stands by outside the air-conditioning target space, the lifting unit is in the lower limit position, so that, for example, the wide part of the opening for passing the transport vehicle according to the lower limit position of the lifting unit. In order to move the article transport vehicle that has been waiting outside the air-conditioning target space toward the air-conditioning target space in order to move the articles in and out of the storage shelf, Since the transport vehicle passage opening can be passed through without being operated, the article transport vehicle can be quickly moved to the air-conditioning target space, and the work efficiency is improved.

  In addition, since articles to be stored in the storage shelf are often carried in at a height corresponding to the lower limit position of the lifting unit by transport means such as a storage conveyor, the lifting unit is positioned at the lower limit position. Thus, when an article to be stored in the storage shelf is brought in from the outside, it is possible to support the article to be stored without significantly raising and lowering the lifting unit, and the work efficiency of the storage process is improved. .

As described above, according to the third characteristic configuration of the present invention, it is possible to obtain an article storage facility that can prevent the article transport vehicle from being broken and that can improve the work efficiency.

  With the above configuration, even when the wide portion Tw is not closed by the automatic door 22, the air flows through the wide portion Tw of the crane passing opening G into and out of the high temperature aging space Z2H. In addition, when the wide portion Tw is closed by the open / close door 22, it is possible to reduce wasteful energy consumption by not operating the wide portion air curtain 28.

  Below, based on the flowchart shown in FIG.7 and FIG.8, control operation | movement of the 2nd stacker crane 5H, the opening / closing door 22, and the air curtain unit 24 by the fixed side controller H1 and the crane side controller H2 is demonstrated.

  The fixed-side controller H1 and the crane-side controller H2 are in a standby state at step # 1 (hereinafter, the term “step” is omitted) until an external conveyance command is issued. At this time, the open / close door 23 is in a state in which the wide portion Tw is closed, the wide portion air curtain 28 is not in operation, and the second stacker crane 5 is in the home position in a state in which the lift carriage 12 is positioned at the lift lower limit position. Waiting at HP. In addition, since the narrow part air curtain 23 is always operating, it is also operating when the second stacker crane 5 is standing by at the home position HP.

  When a warehousing command or a warehousing command is commanded from the outside, the command type is discriminated at # 2, and if the conveyance command is a warehousing command, the control operation is shown as # N1 or lower, and if it is a warehousing command, circle A The control operation shown in FIG.

  The warehousing command is instructed by the host management computer when the warehousing object is carried into the article receiving position set at the conveyance terminal portion of the warehousing conveyor 8, and the warehousing command is high temperature for a predetermined aging time. This is instructed when an article stored in the aging space Z2H is to be taken out from the article storage section 2 of the storage shelf 3 and transported to an article delivery position set at the transport start end of the delivery conveyor 9.

  First, a case where a warehousing instruction is instructed will be described. At # N1, the second stacker crane 5H that has been waiting at the home position HP picks up the goods to be stored that have been carried into the article receiving location by the storage conveyor 8.

  Preparation for passing the second stacker crane 5H by opening the wide door Tw of the crane passing opening G by operating the wide part air curtain 28 at # N2 and opening the automatic door 22 at # N3. do.

  In # N4, the travel of the traveling cart 10 is started. Thereby, the second stacker crane 5H starts to travel from the home position HP toward the target travel position corresponding to the target stop position with respect to the article storage unit designated by the warehousing command. When the second stacker crane 5H is positioned at the internal determination position Pin set on the opposite position OP side by a predetermined distance from the position where the automatic door 22 is installed, it is determined Yes at # N5, and at # N6 The automatic door 22 is closed, and the operation of the wide air curtain 28 is finished at # N7.

  As a result, after the second stacker crane 5H travels from the outside to the inside of the high temperature aging space Z2H and passes through the crane passage opening G, the wide portion Tw is closed and the wide portion air curtain 28 is stopped. It becomes a state. Even when the wide portion Tw is in the closed state, the control infrared ray or the distance measuring laser beam is passed through the door lower end opening Gd formed at the lower end of the automatic door 22 located at the closed position. Similarly to the case where the stacker crane 5H is located on the home position HP side (outside the high temperature aging space Z2H) from the automatic door 22, the operation of the second stacker crane 5H located inside the high temperature aging space Z2H can be controlled.

  When the second stacker crane 5H exceeds the internal determination position Pin, the lifting operation of the lifting carriage 12 is started at # N8. As a result, the second stacker crane 5H moves the carriage 10 to the target lift position corresponding to the target stop position while the traveling carriage 10 moves along the travel path 4 toward the target travel position corresponding to the target stop position. It will be in the state which rises along the raising / lowering mast 11 toward it. At # N9, the traveling carriage 10 stops at the target traveling position, and the lifting carriage 12 stops at the target lifting position. It should be noted that the travel stop and the lift stop timing are not necessarily the same.

  In # N10, the goods to be received are transferred to the article storage unit 2 of the storage shelf 3 designated by the storage instruction. If a delivery command is instructed as the next transport command when the transfer is completed, it is determined Yes in # N11, the process proceeds to #SS, and the subsequent control flow in the delivery process shown in FIG. Merge onto the circle B mark. When the next transfer command is not commanded when the transfer is completed, or when the command is a warehousing command even if the transport command is commanded, it is determined No in # N11, and the second stacker In order to return the crane 5H to the home position HP, control of # N12 and below is performed.

  At # N12, the lowering operation of the elevating carriage 12 is started, and the traveling carriage 10 is caused to travel toward the home position HP. The traveling carriage 10 stops once when traveling to the internal determination position Pin at # N13 and # N14. Then, in # N15, it is checked whether the elevating carriage 12 is lowered to the lower limit position. If it is not the lower limit position, the traveling carriage 10 stands by in a traveling stop state until the lowering operation is completed.

  When it is determined at # N15 that the elevating carriage 12 has been lowered to the lower limit position, the operation of the wide air curtain 23 is started at # N16, the automatic door 22 is opened at # N17, and the traveling carriage at # N18 Ten runs are started.

  Note that the traveling carriage 10 may not be stopped at # N14 if the lowering operation of the elevating carriage 12 has already been completed before the traveling carriage 10 reaches the internal determination position Pin at # N16. In this case, the opening operation of the automatic door 22 is started when it passes through the set travel position set in consideration of the time required for the opening operation of the automatic door 22, and the wide air curtain 23 The operation may be started substantially simultaneously with or just before the opening operation.

  The second stacker crane 5H that resumes traveling at # N18 travels at # N19 and # N20 until it is positioned at the home position HP, and when it reaches the home position HP, the traveling stops. At this time, the elevating carriage 12 is maintained at the elevating lower limit position.

  Thus, the second stacker crane 5H passes from the inside of the high-temperature aging space Z2H toward the outside through the crane passing opening G in which the wide portion Tw is opened in a state where the lifting carriage 12 is positioned at the lower limit position. Run.

  When the second stacker crane 5H stops at the home position HP, the automatic door 22 is closed at # N21 and the wide portion Tw is closed. At # N22, the operation of the wide portion air curtain 28 is stopped.

  Thus, in the case where the second stacker crane 5H does not carry out the work of putting in and out the articles with respect to the storage shelf 3, the automatic door 22 is in a state in which the wide portion Tw is closed and the lift carriage 12 is in the lift lower limit position. It waits outside the high temperature aging space Z2H.

  The case where the warehousing command is instructed has been described above. Next, the case where the warehousing command is instructed will be described. Note that. Some of the control operations of the fixed-side controller H1 and the crane-side controller H2 based on the exit command are completely the same as those of the control operation based on the already-described entrance command. .

  As shown in FIG. 7, among the control operations in the case of the exit command, the control operations of # S1 to # S8 are the same as # N2 to # N9 of the control operation in the case where the entrance command is instructed. That is, by the control operations of # S1 to # S8, the opening / closing operation of the automatic door 22 and the operation start and stop of the wide portion air curtain 28 are controlled in accordance with the passage timing of the crane passage opening G of the second stacker crane 5H. On the other hand, the second stacker crane 5H is configured in such a manner that the lifting carriage 12 passes through the crane passing opening G while the lifting carriage 12 is maintained at the lifting lower limit position, and the lifting carriage 12 starts the lifting operation after passing through the crane passing opening G. The traveling carriage 10 and the raising / lowering carriage 12 move from the home position HP to a target traveling position and a target raising / lowering position corresponding to the target stop position for the article storage unit 2 designated by the delivery command.

  In step S9, the articles stored in the article storage section 2 designated by the delivery command are received by the article transfer device 12b of the lifting carriage 12.

  The control operations from # S10 to # S20 are the same as # N12 to # N22 of the control operation when the warehousing command is instructed. That is, by the control operations of # S10 to # S20, the opening / closing operation of the automatic door 22 and the operation start / stop of the wide portion air curtain 28 are controlled in accordance with the passage timing of the crane passing opening G of the second stacker crane 5H. On the other hand, after the elevating carriage 12 is lowered to the elevating lower limit position, the traveling carriage 10 and the elevating carriage 12 of the second stacker crane 5H are unloaded in a manner of passing through the crane passing opening G while maintaining the state. It moves from the travel position corresponding to the article storage unit 2 specified by the command and the lift position after the transfer operation to the home position HP.

  Then, in # S21, the goods to be delivered are wholesaled at the article delivery location of the delivery conveyor 9, and the delivery operation is completed.

  As described above, in the present embodiment, the lower part of the crane passing opening G is formed as the wide part Tw through which the lifting carriage 12 can pass, and the remaining partial narrow part Tn is formed. The narrow portion air curtain 23 is provided with an automatic door 23 that can be opened and closed at the wide portion Tw to prevent air from flowing into and out of the high temperature aging space Z2H.

  The fixed controller H1 and the crane-side controller H2 are configured such that the second stacker crane 5H passes through the crane passage opening G with the wide portion Tw opened, and the second controller H2 with the wide portion Tw closed. When a warehousing command or a warehousing command is commanded so that the stacker crane 5H waits at the home position HP, the opening / closing operation of the automatic door 22, the operation start / stop of the wide part air curtain 28, and the operation of the second stacker crane 5H It controls the operation.

  In the present embodiment, even if the height of the storage shelf 3 is increased to improve the storage capacity, it is only necessary to increase the length of the narrow portion Tw and provide more air curtain units 24. Therefore, it is possible to suppress air from flowing into and out of the high temperature aging space Z2H through the crane passing opening G without any inconvenience.
