Abstract
Description
Technical Field
[0001] The present invention relates to a device provided with a temperature-controlled section for controlling the temperature of a storage container and a temperature-sensitive product contained in the storage container before the storage container and the temperature-sensitive product contained in the storage container are inserted into a storage and retrieval system. Background Art
[0002] FIG. 1 discloses a prior art automated storage and retrieval system 1 having a frame structure 100, and FIGS. 2, 3, and 4 disclose three different prior art container handling vehicles 201, 301, 401 adapted to operate on such a system 1.
[0003] The frame structure 100 includes upright members 102 and a storage volume including storage rows 105 arranged in rows between the upright members 102. In these storage rows 105, storage containers 106 (also referred to as bins) are stacked one on top of the other to form stacks 107. The members 102 can generally be made of metal, such as extruded aluminum profiles.
[0004] The frame structure 100 of the automated storage and retrieval system 1 includes a track system 108 disposed across the top of the frame structure 100, on which a plurality of container handling vehicles 201, 301, 401 can operate to lift storage containers 106 from the storage rows 105 and lower the storage containers 106 into the storage rows 105, and also to transport the storage containers 106 above the storage rows 105. The track system 108 includes a first set of parallel tracks 110 arranged to guide the container handling vehicles 201, 301, 401 to move along a first direction X across the top of the frame structure 100, and a second set of parallel tracks 111 arranged perpendicular to the first set of tracks 110 to guide the container handling vehicles 201, 301, 401 to move along a second direction Y perpendicular to the first direction X. The containers 106 stored in the rows 105 are accessed by the container handling vehicles 201, 301, 401 through access openings 112 in the track system 108. The container handling vehicles 201, 301, 401 can move laterally above the storage rows 105, i.e., in a plane parallel to the horizontal X-Y plane.
[0005] The upright members 102 of the frame structure 100 can be used to guide the storage containers during the process of lifting the containers out of the rows 105 and lowering the containers into the rows 105. The stacks 107 of the containers 106 are generally self-supporting.
[0006] Each prior art container handling vehicle 201, 301, 401 includes a vehicle body 201a, 301a, 401a, and a first set of wheels and a second set of wheels 201b, 201c, 301b, 301c, 401b, 401c, which respectively enable the container handling vehicles 201, 301, 401 to move laterally in the X direction and the Y direction. In FIGS. 2, 3, and 4, two wheels in each set are fully visible. The first set of wheels 201b, 301b, 401b are arranged to engage two adjacent tracks of the first set of tracks 110, and the second set of wheels 201c, 301c, 401c are arranged to engage two adjacent tracks of the second set of tracks 111. At least one of the wheel sets 201b, 201c, 301b, 301c, 401b, 401c can be lifted and lowered so that the first set of wheels 201b, 301b, 401b and / or the second set of wheels 201c, 301c, 401c can engage the corresponding set of tracks 110, 111 at any given time.
[0007] Each prior art container handling vehicle 201, 301, 401 also includes a lifting device for vertically transporting the storage container 106, such as raising the storage container 106 from the storage row 105 and lowering the storage container 106 into the storage row 105. The lifting device includes one or more clamping / engaging devices adapted to engage the storage container 106, and the clamping / engaging device can be lowered from the vehicles 201, 301, 401 so that the position of the clamping / engaging device relative to the vehicles 201, 301, 401 can be adjusted in a third direction Z orthogonal to the first direction X and the second direction Y. In FIG. 2, the clamping device of the container handling device 201 is located within the vehicle body 201a and is thus not shown.
[0008] Generally, and also for the purposes of the present application, Z = 1 represents the uppermost layer available for the storage containers below the tracks 110, 111, i.e., the layer immediately below the track system 108, Z = 2 represents the second layer below the track system 108, Z = 3 represents the third layer, and so on. In the exemplary prior art disclosed in FIG. 1, Z = 8 represents the lowermost bottom layer of the storage containers. Similarly, X = 1…n and Y = 1…n represent the positions of each storage row 105 in the horizontal plane. Thus, as an example, and using the Cartesian coordinate system X, Y, Z indicated in FIG. 1, the storage container identified as 106' in FIG. 1 can be said to occupy the storage position X = 17, Y = 1, Z = 6. The container handling vehicles 201, 301, 401 can be said to travel in layer Z = 0, and each storage row 105 can be identified by its X and Y coordinates. Thus, the storage containers extending above the track system 108 shown in FIG. 1 are also said to be arranged in layer Z = 0.
[0009] The storage volume part of the frame structure 100 is generally referred to as the grid 104, where the possible storage positions within this grid are called storage cells. Each storage column can be identified by positions in the X and Y directions, and each storage cell can be identified by the container number in the X, Y, and Z directions.
[0010] Each of the prior art container handling vehicles 201, 301, 401 includes a storage compartment or space for receiving and loading the storage container 106 when transporting the storage container 106 across the track system 108. The storage space can include a cavity arranged inside the vehicle bodies 201a, 401a, as shown in FIGS. 2 and 4, and as described, for example, in WO2015 / 193278A1 and WO2019 / 206487A1, the contents of which are incorporated herein by reference.
[0011] FIG. 3 shows an alternative configuration of the container handling vehicle 301 having a cantilever structure. Such a vehicle is described in detail, for example, in NO317366, the contents of which are also incorporated herein by reference.
[0012] The chamber-type container handling vehicle 201 shown in FIG. 2 can have a coverage area covering a certain region, the dimensions of which in the X and Y directions are approximately equal to the lateral extent of the storage column 105, for example, as described in WO2015 / 193278A1, the contents of which are incorporated herein by reference. The term "lateral" used herein can refer to "horizontal".
[0013] Alternatively, the chamber-type container handling vehicle 401 can have a coverage area larger than the lateral area defined by the storage column 105, as shown in FIGS. 1 and 4, for example, as disclosed in WO2014 / 090684A1 or WO2019 / 206487A1.
[0014] The track system 108 generally includes tracks having grooves in which the wheels of the vehicle run. Alternatively, the tracks can include upwardly projecting elements, where the wheels of the vehicle include flanges to prevent derailment. These grooves and upwardly projecting elements are collectively referred to as guide rails. Each track can include one guide rail, or each of the tracks 110, 111 can include two parallel guide rails. In other track systems 108, each track in one direction (e.g., the X direction) can include one guide rail, and each track in the other perpendicular direction (e.g., the Y direction) can include two guide rails. Each of the tracks 110, 111 can also include two guide rail members fastened together, each guide rail member providing one of the pair of guide rails provided by each track.
[0015] WO2018 / 146304A1 (the contents of which are incorporated herein by reference) shows a common configuration of the track system 108, which includes tracks and parallel guide rails in the X and Y directions.
[0016] In the frame structure 100, most of the columns are storage columns 105, i.e., columns 105 in which storage containers 106 are stored in stacks 107. FIG. 5 shows the lowermost layer of a plurality of storage columns, where the containers 106 are placed in the lowest position, e.g., adjacent to the floor of the facility.
[0017] As can be seen in FIG. 5, the storage column 105 is defined by four upright members 102. Guide profiles 103 are arranged on the upright members 102 to hold the containers within the bounds of the storage column 105 and to guide the container when it is raised or lowered by a container handling vehicle. The guide profile 103 consists of two faces 103a which are arranged at 90 degrees and positioned to hold the corners of the container 106. As further shown in FIG. 5, the frame structure can be enclosed by a wall 111, and the storage column 105 adjacent to the wall 111 is shown in this figure.
[0018] In addition to the storage columns 105, there are also columns in the frame that can have other purposes. In FIG. 1, columns 119 and 120 are such dedicated columns which are used by container handling vehicles 201, 301, 401 to deposit and / or pick up storage containers 106 so that they can be transported to an access station (not shown), where the storage containers 106 can be accessed from outside the frame structure 100, or transferred out of or into the frame structure 100. In the art, such locations are generally referred to as "ports", and the columns in which the ports are located can be referred to as "port columns" 119, 120. The transport to the access station can be in any direction, i.e., horizontal, inclined and / or vertical directions. For example, the storage container 106 can be placed in a random or dedicated column 105 within the frame structure 100 and then picked up by any container handling vehicle and transported to the port columns 119, 120 for further transport to the access station. The transport from the port to the access station may require movement in various different directions by means such as carrier vehicles, trolleys or other transport lines. It should be noted that the term "inclined" means the transport of the storage container 106 having a generally transport direction somewhere between horizontal and vertical.
[0019] In FIG. 1, the first port column 119 can be, for example, a dedicated unloading port column, where the container handling vehicles 201, 301, 401 can unload the storage containers 106 to be transported to an access station or a transfer station, and the second port column 120 can be a dedicated pick-up port column, where the container handling vehicles 201, 301, 401 can pick up the storage containers 106 that have been transported from an access station or a transfer station.
[0020] An access station can generally be a pick-up station or a deposit station where product items are removed from or located in a storage container 106. At the pick-up or deposit station, the storage container 106 is generally not removed from the automated storage and retrieval system 1 but instead returns to the frame structure 100 after access. The ports can also be used to transfer the storage container to another storage facility (e.g., to another frame structure or to another automated storage and retrieval system), to a transport vehicle (e.g., a train or a truck), or to a production facility.
[0021] A conveyor system including conveyors is generally used to transport the storage container between the port columns 119, 120 and the access station.
[0022] If the port columns 119, 120 and the access station are at different heights, the conveyor system can include a lifting device having a vertical member for vertically transporting the storage container 106 between the port columns 119, 120 and the access station.
[0023] The conveyor system can be arranged to transfer the storage container 106 between different frame structures, e.g., as described in WO2014 / 075937A1, the content of which is incorporated herein by reference.
[0024] When accessing a storage container 106 stored in one of the columns 105 disclosed in FIG. 1, one of the container handling vehicles 201, 301, 401 is instructed to retrieve the target storage container 106 from its location and transport it to the unloading port column 119. This operation includes moving the container handling vehicle 201, 301, 401 to a position above the storage column 105 where the target storage container 106 is located, using the lifting device (not shown) of the container handling vehicle 201, 301, 401 to retrieve the storage container 106 from the storage column 105, and transporting the storage container 106 to the unloading port column 119. If the target storage container 106 is deep within a stack 107, i.e., one or more other storage containers 106 are located above the target storage container 106, this operation also includes temporarily moving the storage containers located above before lifting the target storage container 106 from the storage column 105. This step, sometimes referred to in the art as "digging", can be performed using the same container handling vehicle that is subsequently used to transport the target storage container to the unloading port column 119, or using one or more other cooperating container handling vehicles. Alternatively or additionally, the automated storage and retrieval system 1 can have a container handling vehicle 201, 301, 401 dedicated to the task of temporarily removing storage containers 106 from the storage column 105. After the target storage container 106 is removed from the storage column 105, the temporarily removed storage container 106 can be repositioned into the original storage column 105. However, the removed storage container 106 can alternatively be repositioned into other storage columns 105.
[0025] When the storage container 106 is to be stored in a storage column 105, one of the container handling vehicles 201, 301, 401 is instructed to pick up the storage container 106 from the pick-up port column 120 and transport it to the position above the storage column 105 where the storage container is to be stored. After removing any storage containers 106 located at or above the target position within the stack 107, the container handling vehicles 201, 301, 401 position the storage container 106 at the desired position. Then, the removed storage container 106 can be lowered back into the storage column 105 or repositioned to another storage column 105.
[0026] To monitor and control the automated storage and retrieval system 1, such as monitoring and controlling the position of each storage container 106 within the frame structure 100, the contents of each storage container 106, and the movement of the container handling vehicles 201, 301, 401 so that the desired storage container 106 can be delivered to the desired position at the desired time without the container handling vehicles 201, 301, 401 colliding with each other, the automated storage and retrieval system 1 includes a control system 500, which is typically computerized and typically includes a database for tracking the storage containers 106.
[0027] Inserting storage containers into the system
[0028] The automated storage and retrieval system 1 typically includes several thousand storage containers 106. When initially constructed at a location, these several thousand storage containers must be inserted into the system as a whole. Similarly, if an existing system is expanded, many additional containers will need to be inserted into the system during a large number of operations. As can be understood, such a large number of insertions of storage containers (or "bins") is difficult and time-consuming.
[0029] Currently, each of these storage containers is manually inserted through the port columns 119, 120 of the automated storage and retrieval system, and the container handling vehicles 201, 301, 401 pick them up from these port columns and transport them to their storage positions within the frame structure.
[0030] Since the operation of manually inserting containers takes a large amount of time, one or more access stations for container / bin insertion will be occupied and cannot be used for their intended purposes.
[0031] Therefore, an automated insertion solution is needed that is less cumbersome for inserting storage containers and avoids occupying the access stations so that the access stations will be free to perform their normal operations.
[0032] Temperature-controlled section of the storage system
[0033] Automated storage and retrieval systems are increasingly being used to store temperature-sensitive goods. One such area of application is cold storage for temperature-sensitive goods. In a cold storage facility, the temperature within the automated storage and retrieval system can be regulated to store the goods according to the requirements of the goods stored in the system. For example, there may be areas within the automated storage and retrieval system where goods are stored at temperatures in the range of 0 to 4 degrees Celsius, such as goods like food are refrigerated. While in other areas, the goods can be stored at much lower temperatures (in the range of minus 18 degrees Celsius) where they need to be frozen.
[0034] When such temperature-sensitive goods are to be introduced into the automated storage and retrieval system, they are manually placed in a storage container that is already operating within the system and are redeposited into the system through an access station. This presents several challenges as the redepositing has to be carried out manually by personnel, which occupies the access station and renders it unavailable for order fulfillment. Additionally, the goods must be kept at the appropriate temperature prior to redepositing.
[0035] This in turn increases costs as any goods that thaw or heat up while waiting for redepositing may have to be discarded. Therefore, the system requires a more efficient way of redepositing temperature-controlled goods such as food.
[0036] Accordingly, there is a need for an apparatus and method for automatically depositing and / or redepositing temperature-sensitive goods into a temperature-controlled section of an automated storage and retrieval system. SUMMARY OF THE INVENTION
[0037] The present invention relates to a temperature-controlled storage container insertion device and a method for depositing or redepositing temperature-sensitive goods into a temperature-controlled section of an automated storage and retrieval system. According to the present invention, the device is arranged to automatically insert a storage container containing temperature-sensitive goods into the automated storage and retrieval system for eventual storage in the temperature-controlled section of the system. The present invention also relates to an apparatus for handling goods in a refrigerated or frozen container related to the insertion operation.
[0038] According to one aspect of the present invention, goods are deposited / redeposited into the storage and retrieval system by "inserting" a container containing the goods into the storage and retrieval system. As used herein, the term "inserting" a storage container or "bin" into an automated storage and retrieval system refers to the terminology in the art, which includes steps of attaching an identification label having a machine-readable identification code to the new container and recording the container into the control system of the facility. The physical dimensions of the container are scanned or otherwise measured to ensure that the dimensions of the container are within a predetermined tolerance. The goods can also be recorded into a warehouse management system that tracks the inventory of goods within the automated storage and retrieval system.
[0039] In one aspect of the present invention, the container insertion device of the present invention is arranged to insert the container laterally into an empty storage column of the system, rather than inserting it via the access station. According to this aspect of the present invention, the automated storage and retrieval system is provided with a lateral opening, door or cutout in the wall of the frame structure surrounding the storage and retrieval system at or near the floor of the facility in which the automated storage and retrieval system is installed. The opening provides an entrance to the storage column arranged at the periphery of the frame structure and adjacent to the wall. In the case where there is no wall surrounding the frame structure, a plurality of storage columns will be exposed at the periphery of the frame structure.
[0040] The storage container insertion device of the present invention (hereinafter referred to as "container insertion device" or "insertion device") can be transported to this opening, for example, by rolling on wheels, thus allowing the container to be inserted into the automated storage and retrieval system via the exposed storage column without occupying the port column at the access station for the purpose of temporarily inserting the container. This allows container insertion to be performed while the automated storage and retrieval system is operating without occupying the access station.
[0041] In one aspect of the present invention, the insertion device includes a conveyor for transporting the container to be inserted from the rear of the device to the front of the device. As the container is transported along the conveyor, it passes through a temperature-controlled section and one or more automatic container preparation devices for performing tasks related to preparing the container to be inserted into the system, such as one or more temperature sensors, labeling devices, scanners, cameras, and / or other devices for measuring the dimensions of the container. In one aspect, the container preparation devices are installed in or on a compartment having a through-channel with an entrance and an exit provided with doors through which the conveyor transports the container. However, these devices can be suspended above the compartment or on the side of the conveyor within the compartment by supports or other means.
[0042] According to one aspect, the compartment of the device includes a temperature-controlled section provided with refrigeration equipment for controlling the temperature and refrigerating or freezing temperature-sensitive goods stored in the storage container passing through the compartment. The refrigeration equipment can be a quick chiller, a freezing unit, or any other suitable refrigeration equipment known in the art. The compartment is provided with an entrance door and an exit door to provide a temperature-controlled environment within the compartment, which is necessary to achieve the correct temperature for the temperature-sensitive goods stored in the container.
[0043] The insertion device is also provided with a support or platform that extends outwardly from the device and is arranged to be laterally inserted into a storage row exposed by an opening in the wall. The lateral dimensions of the platform are substantially the same as the lateral dimensions of the storage container to allow the container to rest on the platform inside the storage row. In use, the storage container will be transported by a conveyor through the insertion device, past a temperature-controlled section and various automatic container preparation devices, and transported to rest on the support or platform within the storage row, where the container will await removal by a container handling vehicle that lowers its gripping means into the storage row. Then, the storage container with temperature-sensitive goods is placed in the temperature-controlled section of the automated storage and retrieval system. As can be appreciated, the insertion operation will thus greatly reduce the interference with the throughput of the system that would occur if one or more of the several access stations were diverted from their normal function to the task of container insertion. After the container insertion operation is completed, the device can be removed, and the storage row can be used for normal storage of the containers.
[0044] As described above in the background section, the storage rows of prior art automated storage and retrieval systems are defined by four upright members. These upright members typically include guide profiles that help keep the corners of the containers within the bounds of the storage row. Thus, such guide profiles would prevent the lateral insertion of a storage container or the platform of the insertion device into the storage row. Accordingly, another aspect of the present invention provides a method for laterally inserting a container into a storage row.
[0045] In one aspect, the method for laterally inserting a storage container can be to provide a lateral opening in the guide profiles of two upright members adjacent to the opening in the wall. For example, a portion of the face of the guide profile located between the opening in the wall and the storage row can be cut away at a height at least as high as the container. The platform of the insertion device and the container can thus be inserted into the storage row through this lateral opening in the guide profile. An alternative solution is to provide a movable section in the face of the guide profile located between the opening in the wall and the storage row, whereby the movable section can be pushed to one side to allow the container to be laterally inserted. Examples of such movable sections include a slidable section that can slide up or down or a hinged section that can be pushed in or pulled out. In one example, the movable section can include a spring-loaded hinged section such that when the platform of the insertion device is inserted into the storage row, the platform pushes these sections inward against the force of the spring, thereby allowing the platform and the container to enter the storage row laterally. When the platform is removed, the spring will snap these sections back into place, where they can resume their guide profile function.
[0046] The storage container that houses temperature-sensitive goods and is to be inserted into the temperature-controlled section of an automated storage and retrieval system is carried by a conveyor that transfers the storage container towards the entrance door of the passage of the compartment of the device. At the compartment, the storage container with temperature-sensitive goods passes through the temperature-controlled section that includes refrigeration equipment, and various container preparation devices prepare the container for insertion into the automated storage and retrieval system. For example, a labeling device attaches a label / identification placard to the storage container. The label is scanned by a scanner or otherwise recorded, and the information associated with the container is input into the control system of the storage and retrieval system. A scanner or other device measures the dimensions of the container to ensure that the container meets the predetermined dimensional limits. The device may also include a camera to record an image of the storage container. A machine-readable label that identifies the contents of the container may also be attached to the container. A scanning device can scan this label and record the contents into the warehouse management system.
[0047] As described above, the container and its contents are also transported through the temperature-controlled section where, depending on the nature of the goods, the contents are refrigerated or frozen to a predetermined temperature. The control system of the storage system can transmit temperature information to the refrigeration equipment. In one aspect, the control system can control the opening and closing of the entrance door and the exit door leading to the compartment, which ensures that the goods within the container have reached the predetermined temperature.
[0048] After the container has passed through the various container preparation devices and is confirmed to be ready for insertion into the storage system, and the goods have been refrigerated or frozen to the desired temperature, the storage container is transferred by the conveyor to be placed on a support or platform within the storage column. In one aspect, the goods can be cooled to a temperature below the expected storage temperature to compensate for any warming of the contents due to the travel time from the insertion device to the final destination.
[0049] Then, the control system instructs the container handling vehicle that the storage container is ready to be picked up from the storage column.
[0050] According to one aspect, the present invention relates to a container insertion device for laterally inserting a storage container into an automated storage and retrieval system through a storage column of the system, the device comprising:
[0051] - a compartment having an entrance, an exit, and a passage for transporting the storage container between the entrance and the exit, wherein the compartment includes a temperature-controlled section that includes refrigeration equipment for reducing the temperature of the container and / or the contents of the container,

[0095] In the following, embodiments of the present invention will be discussed in more detail with reference to the accompanying drawings. However, it should be understood that the drawings are not intended to limit the present invention to the subject matter depicted therein.
[0096] The frame structure 100 of the automated storage and retrieval system 1 is constructed in a manner similar to the frame structure 100 of the prior art described above in connection with FIGS. 1 to 5, i.e., the frame structure 100 surrounded by the wall 111 includes a plurality of upright members 102 and includes a first upper track system 108 extending in the X and Y directions.
[0097] The frame structure 100 further includes storage compartments provided in the form of storage columns 105 between the members 102, wherein storage containers 106 can be stacked in the storage columns 105 in the form of stacks 107.
[0098] The frame structure 100 can be of any size. In particular, it should be understood that the frame structure can be much wider and / or much longer and / or much deeper than that disclosed in FIG. 1. For example, the frame structure 100 can have a horizontal extent of more than 700×700 columns and a storage depth of more than twelve containers.
[0099] Now reference will be made to Figures 6 to 14 Aspects of the device and method for inserting a storage container with temperature-sensitive goods into an automated storage and retrieval system according to the present invention will be discussed in more detail.
[0100] Throughout the specification, the storage container 106 can alternatively be referred to as a box. In addition, the container insertion device, the box insertion device, and the insertion device can be used interchangeably. The support and the platform 607 can also be used interchangeably.
[0101] Figure 6 is a perspective view of the automated storage and retrieval system 1. The frame structure of the automated storage and retrieval system is surrounded by a wall 111. Although Figure 6Depicts the wall 111, but it should be understood that the automated storage and retrieval system may include a frame structure not surrounded by walls. According to one aspect of the present invention, an opening 501 is formed in the wall 111 to expose the storage column 105. Obviously, if there is no wall surrounding the frame, the opening 501 is not required. The opening 501 provides a lateral access to the storage column 105 of the frame structure adjacent to the wall, preferably at or near the lowermost layer of the storage column 105. Figure 6 Shows a single opening 501. However, it should be understood that according to the present invention, a plurality of openings 501 may be provided. The storage column 105 exposed by the opening 501 preferably has no containers. The opening 501 may be a simple opening as depicted, or may have a door or panel that can be selectively opened or closed.
[0102] Figure 7 Depicts an embodiment of the container insertion device 600 of the present invention, which is positioned Figure 6 near the opening 501 in the wall 111 (and hides the opening). According to one aspect, the container insertion device 600 is a portable device. According to one aspect, the container insertion device 600 includes wheels 611 that allow the container insertion device to roll along the floor 613 of the facility in which the automated storage and retrieval system is installed at the opening 501.
[0103] The container insertion device 600 includes a conveyor 603 that is arranged to transport the container 106 to be inserted into the storage and retrieval system from the rear 614 of the insertion device to the front 615 of the insertion device. The device includes a compartment 601 having a through-channel 602. The through-channel 602 has an inlet 608 and an outlet 609. The inlet 608 and the outlet 609 may be provided with doors to help regulate the temperature in the channel 602. Alternatively, the inlet 608 and the outlet 609 may include air curtains. The channel 602 also includes a temperature-controlled section having refrigeration equipment 621, the details of which will be discussed in Figure 13 below.
[0104] In this embodiment, the conveyor 603 is arranged to longitudinally transport the storage container 106 through the channel 602. The conveyor 603 is preferably an automatic conveyor belt that is controlled by the control system 500 of the automated storage and retrieval system.
[0105] The container insertion device 600 further includes a channel including a temperature-controlled section having refrigeration equipment, and one or more container preparation devices for automatically performing functions required to prepare a container for insertion into the temperature-controlled section of the storage and retrieval system. Examples of such container preparation devices include a labeling device 604 arranged to automatically apply a label 604a to the container. The label includes identification information for the container, and the label may include a two-dimensional code or other machine-readable code. In one aspect, the labeling device 604 automatically sends information about the label to the control system 500 of the storage and retrieval system. Additionally or alternatively, the insertion device 600 may include an ID scanner 605 arranged to scan the label 604a and send the identification information of the container to the control system 500. Such an ID scanner may scan the label 604a applied by the labeling device 604, or may be used when the container has a pre-applied identification label. The container preparation device may further include a size scanning device 606, such as a camera, a laser scanner, or other such device for measuring the size of the container. The scanning device 606 is used to measure the physical size of the container to confirm that the size of the container is within a predetermined tolerance before insertion. Additionally, the container preparation device may further include a number of temperature sensors configured to monitor the temperature of the storage container and the goods in the container, as well as the temperature of the channel or compartment as the container passes through the channel or compartment. In one embodiment, the container preparation device is mounted in or on the compartment 601 as shown, however it should be understood that such a device may be supported above or to the side of the conveyor 603 in other ways.
[0106] As Figures 8 to 11 shown, the container insertion device 600 further includes an exit platform or support 607 that longitudinally protrudes beyond the front portion 615 of the device, such as beyond the exit 609 of the compartment 601. The platform 607 is sized to be inserted into the storage column 105 and provides a resting position / support for the container 106 that exits the front portion 615 of the device / compartment 601 and awaits pickup by the container handling vehicle of the system. The platform or support 607 is shown as a platform having a flat surface, however those skilled in the art will understand that the term "platform" in this context will cover other structures performing the same function, such as support rails, etc.
[0107] As shown in FIG. 5, the storage columns in an automated storage and retrieval system are typically defined by four upright members including corner guiding profiles 103. Such guiding profiles hold the storage containers within the bounds of the storage column, but will thereby prevent the lateral insertion of the exit platform 607 of the insertion device and / or the lateral insertion of the storage container by the device. Thus, according to one aspect of the present invention, a lateral opening 617 is formed in the guiding profile to allow such lateral insertion. In Figure 12AIn one embodiment shown, the lateral opening 617 in the guide profile includes a section of the guide profile face 103a of the guide profile that is located between the opening 501 and the storage row 105 and is removed. In Figure 12B In the embodiment shown, the lateral opening 617 in the guide profile includes a hinged section 619 in the guide profile face 103a. The hinged section is arranged to be pushed aside by the platform 607 and / or the container 106, thereby allowing lateral access to the storage row. In one aspect, the hinged section 619 can be spring-loaded such that when the platform 607 is removed, it springs back into place.
[0108] Reference Figures 6 to 14 will explain the sequence of steps in a method of inserting a temperature-controlled storage container with temperature-sensitive goods into the temperature-controlled section of a storage and retrieval system using the device of the present invention.
[0109] First, in the presence of the wall 111 surrounding the frame of the automated storage and retrieval system, an opening 501 is provided in the wall to expose the storage row 105.
[0110] The storage row 105 is modified by providing a lateral opening 617 as shown in Figure 12A and / or Figure 12B to allow lateral insertion of the storage container.
[0111] The container insertion device 600 as described above is transported to the opening 501, for example, by rolling along the floor of the facility and placing it adjacent to the opening, where the support or platform 607 of the device is inserted into the exposed storage row 105.
[0112] As Figure 7 shown, the storage container 106 with temperature-sensitive goods to be inserted into the storage row 106 of the automated storage and retrieval system is placed on the conveyor 603 near the rear 614 of the container insertion device. Then, the storage container 106 is transported by the conveyor 603 towards the compartment 601 containing the temperature-controlled section with refrigeration equipment and towards the support or platform of the device. In one aspect, the conveyor 603 is configured to transport a number of storage containers 106 one by one.
[0113] Figure 8Illustrates the preparation process of a storage container to be inserted into the storage column 106 of an automated storage and retrieval system. In an exemplary embodiment, the storage container 106 may contain temperature-sensitive goods, such as food products that can be refrigerated or frozen products. Information about the food loaded into the storage container is sent to the control system 500 or the warehouse management system, for example, by a scanner that reads a machine-readable label attached to the container. The storage container filled with goods passes through the entrance door of the compartment 602, which includes a passage 602 with container preparation devices. However, the container preparation devices can also be installed at the top horizontal height on a support member extending through the passage 602 of the compartment.
[0114] The container preparation devices thus perform various automated tasks to prepare the container for insertion into the storage and retrieval system. For example, as Figure 8 shown, a labeling device 604 can attach an identification placard or label 604a to the storage container 106. The identification placard can also be a barcode, a QR code, an etching, or other forms of machine-readable information.
[0115] The identification information of the container, together with the information about the goods stored in the container, is transmitted to the control system 500 of the storage and retrieval system. Such information can be transmitted by the labeling device 604 or by a scanning device 605 that can scan the label and transmit the identification information. The scanning device 605 performs the same function when the container is pre-labeled.
[0116] Figure 9 Illustrates that before being inserted into the storage column of the automated storage and retrieval system, a dimensional scanning device 606 checks the dimensions of the storage container and scans it. The dimensional scanning device 606 can be a camera or other types of scanners, such as a laser scanning device. The measured dimensions are compared with a predetermined tolerance. If the dimensions are within the acceptable tolerance, the container is approved for insertion; if the dimensions are outside the tolerance, the container is rejected for insertion, and for example, a warning light or other signal can indicate that the container needs to be removed from the device. The camera 606 can also record an image of the container for various archiving or other purposes.
[0117] Figure 13 Illustrates a storage container processed by the temperature-controlled section of the container insertion device of the automated storage and retrieval system. The temperature-controlled section 620 can include refrigeration equipment 621 to circulate cold air or maintain the temperature below zero according to the type of goods stored in the container. The compartment 601 can include an entrance 608 provided with a door or an air curtain or a PVC curtain. The compartment 601 can also be provided with a plurality of temperature sensors 622 distributed throughout the passage 602 to monitor and record the temperature of the storage container and the goods stored in the storage container throughout the passage 602.
[0118] After the storage container 106 reaches the predetermined temperature required for the goods, a signal that the container is ready to be inserted into the storage system can be sent to the control system 500.
[0119] On the other hand, if the temperature sensor 622 monitors that the temperature of the storage container 106 has not reached the desired temperature required for the goods, the control system 500 can instruct the refrigeration device 621 to adjust the temperature to the required temperature range based on the type of temperature-sensitive goods stored in the container 106.
[0120] Figure 10 Depicted is a storage container leaving the compartment in the container preparation area and approaching a support or platform 607 within the storage column. In one aspect, the support or platform 607 is sized substantially equal to or less than the size of the grid cell occupying the storage column, and the platform has a hinged section 619 that is pushed to one side, or other hinged sections that have passed through the lateral opening 617. Figure 12B Pushed to one side of the hinged section 619, or other hinged sections that have passed through the lateral opening 617.
[0121] As Figure 10 Shown, the storage container 106 that has been approved for insertion arrives on the platform 607 and is placed within the storage column 105 to await pickup by the container handling vehicle. The control unit 500 instructs the container handling vehicle to pick up the storage container 106.
[0122] Figure 11 Shows a close-up view of the storage column 105, where the storage container is placed on the platform of the container insertion device 600 and awaits pickup by the container handling vehicles 201, 301, 401 of the storage system by means of their clamping and lifting devices.
[0123] In addition, for each storage container 106 that houses temperature-sensitive goods inside and is to be inserted into the automated storage and retrieval system 1, the sequence of the above steps is repeated. After all the storage containers 106 have been inserted into the system, the control system can send an instruction to complete the container insertion process. Then, the container insertion device 600 can be removed from the storage column 105. The storage column 105 can then be used as a normal storage column 105 for storing the storage containers 106.
[0124] Figure 12A and Figure 12B Shows an empty storage column adjacent to an opening in the wall of Figure 6 Shows different embodiments of the opening in the guide profile that allows the container to be inserted laterally into the storage column. In Figure 12A , some segments of the face of the guide profile are removed, while in Figure 12B , a hinged segment of the face of the guide profile is shown. Then, the container insertion device is inserted into the empty column through the wall openings of Figure 12A and Figure 12B The wall openings of
[0125] Figure 13 Shows the temperature-controlled section of the container insertion device of the automated storage and retrieval system. As shown, the temperature-controlled section 620 is provided as part of the container insertion device 600. The temperature-controlled section 620 may be integrated with the channel / container handling area 602 of the insertion device. The temperature-controlled section 620 includes refrigeration equipment 621 for controlling the temperature of the container. Examples of such refrigeration equipment include chillers, freezing units, or other refrigeration equipment known in the art.
[0126] According to one aspect, when a storage container containing goods passes through the channel 602, the refrigeration equipment 621 adjusts the temperature to a predetermined value established for the specific goods accommodated in the container. The predetermined temperature can be set by sending an instruction from the control system 500 of the automated storage and retrieval system to the refrigeration equipment 621.
[0127] In one example, if the storage container 106 to be inserted through the container insertion device 500 contains goods that need to be maintained within a predetermined temperature range (e.g., from 0 to 4 degrees Celsius), the control system 500 will instruct the refrigeration equipment to circulate cold air within the channel / container handling area 602 to reach the desired temperature range sufficiently.
[0128] In another example, if the storage container 106 to be inserted through the container insertion device 600 contains a product that needs to be maintained in a frozen state, the refrigeration equipment 621 can be used as a freezing unit to maintain the air within a sub-zero temperature range and circulate the air, and assist in reaching or maintaining the frozen state of the goods.
[0129] Although not explicitly shown in the figure, it should be understood that the refrigeration equipment 621 includes basic components known in the art and will not be discussed in detail here.
[0130] Figure 14 Shows the temperature-controlled section of the automated storage and retrieval system. The automated storage and retrieval system 1 is provided with a section as the temperature-controlled section 630. The temperature-controlled section 630 can be further divided into a refrigerated storage section 631 and a frozen storage section 632. Depending on the nature of the goods, the temperature in the refrigerated storage section can be maintained within any suitable temperature range, e.g., the range can be from 0 to 4 degrees, and can be used for storage of, for example, fresh fruits and vegetables, dairy products, medical supplies, etc. The temperature in the frozen storage section will be at least below zero degrees Celsius, and can be, for example, maintained below minus 18 degrees Celsius, and is used for storage of seafood, meat, poultry, chemicals, and medical supplies.
[0131] When the storage container 106 loaded with temperature-sensitive products is inserted into the container insertion device, it passes through the compartment 601 towards the channel 602 of the device. The control system 500 can send instructions to open the entrance door or curtain provided at the entrance of the compartment 601. The storage container 106 passes through the compartment to reach the channel 602. The temperature-controlled section 620 regulates the temperature within the channel 602 and helps to obtain the refrigerated or frozen temperature required for the storage container 106 and the goods stored in the container.
[0132] In one embodiment, the temperature-controlled section 620 may further include a number of temperature sensors 622 distributed within the channel / container handling area 602. The temperature sensors 622 can be used to check whether the storage container passing through the container insertion device has reached the required temperature based on the type of product loaded in the storage container.
[0133] In another aspect, the control system 500 can communicate with the container insertion device and control and monitor the functions of the insertion device. For example, the control system 500 can monitor and record the temperature measured by the temperature sensors 622 in the channel 602. Based on the recorded temperature, the control system can determine whether the storage container has reached the required temperature based on the contents of the storage container. If the required temperature is not reached, the control system 500 can send a signal to the refrigeration equipment to adjust the temperature.
[0134] When the storage container 106 has reached the required temperature, the control system can send instructions to the (available) container handling vehicle to pick up the storage container from the support through the columns of the storage system.
[0135] In one aspect, the conveyor 603 can include segments configured to move at different speeds. This allows for controlling the movement of the storage container 106 as it passes through the channel 602 of the insertion device. In one example, the first container may contain frozen goods and require a frozen temperature range. Subsequent containers may contain refrigerated goods, such as milk, and thus the temperature of the temperature-controlled section needs to be adjusted before the second container can pass through the channel. Therefore, the second container can pass through the slow-moving segment of the conveyor to allow for a waiting time before the temperature of the temperature-controlled section is adjusted by the control system 500.
[0136] In the above description, various aspects of the transport vehicle and the automated storage and retrieval system according to the present invention have been described with reference to illustrative embodiments. For purposes of explanation, specific numbers, systems, and configurations have been set forth in order to provide a thorough understanding of the system and its operation. However, this specification is not intended to be construed in a limiting sense. Various modifications and variations of the illustrative embodiments and other embodiments of the system that are obvious to those skilled in the art to which the disclosed subject matter pertains are considered to fall within the scope of the present invention.
