Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.
In a dense warehouse, the higher the shelves 100, the more storage space is available and the greater the storage capacity. And when the number of the commodities which can be stored in the shelf 100 is increased, the hit rate of the single shelf 100 is higher, which is beneficial to reducing the use number of the robots. For this reason, those skilled in the art will have a strong desire to expand the pallet 100 upward while still using the transfer robot.
In the application environment to adopting transfer robot to remove goods shelves 100, goods shelves 100 are difficult to realize the problem that upwards expands reliably because of upper portion takes place to rock easily, the utility model provides a select system. As shown in fig. 1 to 4, the picking system according to the present invention includes a rack 100, a first rail 111, a first sliding member 112, and a transfer robot (not shown). The first rail 111 is located at the shelf moving area and is located at the upper side of the shelf 100. The first slide member 112 is connected to at least one of the upper end of the shelf 100 and the side of the shelf 100. The first slide member 112 is slidably engaged with the first rail 111 along the extending direction of the first rail 111. The first sliding member 112 is limited to the first rail 111 along a direction perpendicular to the extending direction of the first rail 111. The transfer robot is configured to be movable at least within the rack movement area. And the top of the transfer robot is disposed corresponding to the bottom of the shelf 100. The transfer robot is used to move the rack 100 in the rack movement area.
The pallet 100 generally includes four sets of columns 102 and a plurality of decks 103. Four sets of studs 102 are located at respective corners of a rectangular laminate 103. The layer plate 103 and the upright post can be detachable or fixed. The layer plates 103 are arranged at intervals along the height direction of the vertical columns.
In implementing this embodiment, the existing shelving 100 may be further raised and the shelving 100 may be further extended toward the top of the warehouse to a position near the top of the warehouse. Alternatively, the pallet 100 may be raised to the ground to carry the total weight of the pallet 100 that can be supported, such as to take into account the weight that can be carried by the transfer robot.
The first rail 111 may be configured without limitation, as long as the first rail 111 can restrict at least the upper portion of the shelf 100 from moving to swing in a direction perpendicular to the first guide rail. Of course, it can be understood by those skilled in the art that, during the movement of the shelf 100, if the clearance between the shelf 100 and the first rail 111 along the height direction of the shelf 100 is small, the first rail 111 may also limit the swing of the shelf 100 along the extending direction of the first rail 111.
According to the present invention, the first rail 111 is provided on the upper side of the rack 100 in the rack movement area, and the first sliding member 112 capable of sliding-fitting with the first rail 111 is provided on at least one of the upper end and the side portion of the rack 100, whereby the rack 100 is moved in the rack movement area by the transfer robot. Since the sliding member is limited to the first rail 111 along the direction perpendicular to the extending direction of the first rail 111, the upper portion of the pallet 100 can be prevented from shaking along the direction perpendicular to the extending direction of the first rail 111 during the movement of the pallet 100 by the transfer robot, which helps to ensure the stability of the pallet 100 during the movement.
Referring to fig. 1 and 3, in addition, to prevent the lower portion of the rack 100 from shifting during movement, the picking system may further include a second rail 121 and a second sliding member 122. The second rail 121 is located below the first rail 111 and is parallel to the first rail 111. The second rail 121 is provided corresponding to the lower portion of the shelf 100. Here, the lower portion of the shelf 100 is understood to be a portion below the center of the shelf 100 in the height direction, that is, a lower half of the shelf 100 in the height direction. The second sliding member 122 may be connected to the lower end of the shelf 100, may be connected to the side of the shelf 100, and may be connected to the lower end of the shelf 100 and the side of the shelf 100, respectively, as long as the second rail 121 corresponds to and can be engaged with the second sliding member 122. The second slide member 122 is slidably fitted to the second rail 121 in the extending direction of the second rail 121. The second sliding member 122 is constrained to the second rail 121 along a direction perpendicular to the extending direction of the second rail 121. Since the second track 121 is parallel to the first track 111, the extending direction of the second track 121 is parallel to the extending direction of the first track 111. In the case where the first rail 111 and the first slide member 112 are already provided, the stability of the entire moving rack 100 can be better ensured by adding the second rail 121 and the second slide member 122.
With reference to fig. 1 and 3, when the carrier robot lifts the rack 100 to start walking, the first rail 111 and the first sliding member 112 are engaged with each other, and the second rail 121 and the second sliding member 122 are engaged with each other, so as to guide the rack 100, prevent the rack 100 from shaking, and stabilize the rack 100.
Referring to fig. 1-3, in addition, the picking system may further include a weighted member (not shown). The weight member is connected to the pallet 100 so that the center of gravity of the pallet 100 in an unloaded state is lower than the center of the pallet 100 in the height direction and the center of the pallet 100 may not be on a vertical line. In the loaded state, depending on the weight of the container on the pallet 100, the center of gravity of the pallet 100 may be below the center of the pallet 100 or the center of gravity of the pallet 100 may be below the center of the pallet 100. The weight member may in particular be arranged at the lowermost shelf, e.g. between a deck and a shelf. In general, the higher the height of the shelf 100 is expanded upward, the higher the center of gravity, so that the upper portion of the shelf 100 is more likely to shake during the movement of the shelf 100, and even to topple over the shelf 100. Therefore, the utility model discloses an add the counter weight component in the lower part of goods shelves 100, can adjust the focus under the empty load state of goods shelves 100 to leaning on down, help preventing that the focus of goods shelves 100 under the full load state is too close to upper portion to can reduce the probability that the upper portion of goods shelves 100 takes place to rock and the range of rocking at the removal in-process of goods shelves 100 to a certain extent, and then further improve the stability of goods shelves 100 at the removal in-process. For example, the configuration member may be a weight. It will be appreciated by those skilled in the art that adjusting the center of gravity of the pallet 100 when empty by providing a weight member can be used as an aid to offset the center of gravity of the pallet 100 in the loaded state downward from the height-wise center of the pallet 100, thereby helping to reduce the amplitude of the sway of the portion of the pallet 100 above the height-wise center.
Referring to fig. 2 to 4, for example, the shelf moving area may include a shelf placement area (not shown) and a shelf resting area (not shown). The shelf placing area is used for placing the shelf 100. The shelf parking area is located on the side of the shelf placing area and used for parking the shelf 100. In addition, the picking system may also include a workstation area and a handling unit 140. The working station area is internally provided with a picking station and can also be provided with a separate sowing station. The workstation district is located the one side that deviates from goods shelves district of berthing the district of goods shelves, and workstation district and goods shelves berth the district interval arrangement. The load handling unit 140 is located at the separation of the workstation area and the rack parking area. The handling unit 140 is configured to be able to transfer containers 150 between the workstation area and the rack parking area. The picking station transfers the containers 150 between the racks 100 of the workstation area and the rack parking area by means of the handling unit 140, i.e. the picking of the containers 150 is effected, or the handling of goods on and off the racks is effected. Wherein, the shelf placing area can also be understood as the stock area of the shelf.
Referring to fig. 1 and 3, the first rail 111 and the second rail 121 may be continuously disposed in the moving area of the shelf. That is, the first rail 111 and the second rail 121 are provided in both the shelf placement area and the shelf resting area, and the entire moving process of the shelf 100 is moved along the guide paths of the first rail 111 and the second rail 121. The internally preset traveling route of the transfer robot is matched with the guide paths of the first rail 111 and the second rail 121.
Referring to fig. 1 and 2, the first rail 111 and the second rail 121 may be discontinuously disposed in the moving area of the shelf. For example, the first rail 111 and the second rail 121 are not provided in the shelf stop area. In this case, in order to facilitate the shelf 100 to be reliably engaged with the ends of the first and second rails 111 and 121 when returning from the shelf resting area, a bell mouth structure may be provided at the ends of the first and second rails 111 and 121.
Referring to fig. 2 through 4, for example, the handling unit 140 may include a frame 141 and a container handling device (not shown). The container handling apparatus is removably attached to the frame 141. The container handling apparatus is used to transfer containers 150 such that the containers are transferred between the shelves 100 of the shelf docking area and the workstation area. The height of the rack body 141 is adapted to the height of the shelf 100, so that the requirements of goods loading and unloading are met. Here, the height of the shelf body 141 is adapted to the height of the shelf 100, and it is understood that the height of the shelf body 141 cannot be lower than the height of the shelf 100, so that the goods loading and unloading operations can be performed for different positions of the shelf 100 in the height direction.
Referring to fig. 2 and 3, in addition, the picking system may further include a positioning member 131 and a finger 132. The spacer 131 is coupled to an upper portion of the body 141 and is disposed corresponding to an upper portion of the shelf 100 at the shelf stop region. The positioning member 131 is used to abut against the shelf 100 at the shelf resting area to limit the distance from the upper portion of the shelf 100 to the body 141. The hook claw 132 is connected to the frame body 141. The hook 132 is used to hook the shelf 100 so that the shelf 100 abuts against the positioning member 131. In the case where the second rail 121 and the second slide member 122 are provided, by providing the hook claw 132 at the loading and unloading unit 140 to hook the upper portion of the rack 100, it is possible to prevent the upper portion of the rack 100 from being shaken when the container 150 is transferred. By providing the spacers 131, the upper portion of the shelf 100 is prevented from being too close to the body 141 such that the upper portion of the shelf 100 is inclined toward the body 141. The size of the spacer 131 may be set according to the distance between the lower portion of the shelf 100 and the body 141. For example, the positioning member 131 may enable the distance from the upper portion of the shelf 100 to the shelf body 141 to be equal to the distance from the lower portion of the shelf 100 to the shelf body 141, thereby ensuring that the pick-up distance is consistent for any floor of the entire shelf 100. The position of the hook 132 on the frame body 141 may be selectively provided on the upper portion of the frame body 141 to correspond to the upper portion of the hook shelf 100.
With continued reference to fig. 2 and 3, the positioning member 131 may be configured as a positioning block, for example. The positioning block may be mounted on the frame body 141 by using a detachable fastener such as a screw, or may be fixed on the frame body 141 by welding, riveting, or the like. The hook claw 132 may be configured as an L-shaped hook, or may be a hook of another shape as long as the shelf 100 can be reliably hooked. The claw 132 may be mounted to the frame 141 in a pivotally, telescopically, slidably, or other movable mounting manner. It will be appreciated by those skilled in the art that the fingers 132 need to be able to switch between an escape position to avoid movement of the pallet 100 and an operative position to hook the pallet 100 during movement of the pallet 100 into and out of the pallet parking area. For example, before the shelf 100 is to be moved into the shelf stop area, the hook 132 is moved to the avoiding position, so as to prevent the interference with the hook 132 during the movement of the shelf 100 into the shelf stop area; after the shelf 100 has been moved completely into the shelf resting area, the hook 132 is moved to the operative position to hook the shelf 100 so that the shelf 100 remains stable during the loading and unloading of goods. Similarly, before the shelf 100 is to be moved out of the shelf stop area, the hook 132 is moved to the avoidance position to prevent the shelf 100 from interfering with the hook 132 during movement out of the shelf stop area.
The motive force for the movement of the fingers 132 may be from a manual or powered source. For example, a power device or equipment such as a motor, an air cylinder, or an electric cylinder may be provided on the frame body 141 as a power source, and the power source may be connected to the hook 132 to drive the hook 132 to move between the avoiding position and the operating position.
Referring to fig. 2-4, the workstation area may further include a transport line 142. The conveyor line 142 can be used to receive containers 150 transferred from the handling unit 140 or to transport containers 150 located on the conveyor line 142 to the handling unit 140. In the workstation area, the operator at the picking station may place the goods into the empty containers 150 of the conveyor line 142, may remove the goods from the containers 150 of the conveyor line 142, and the conveyor line 142 may transport the containers 150 with the goods to the loading and unloading unit 140, or may transport the empty containers 150 to the picking station. Conveyor line 142 may include, but is not limited to, a conveyor line 142 located between the picking station and the handling unit 140. The conveying line 142 may be configured as, but not limited to, a roller conveying line 142, or a chain conveying line 142.
Referring to fig. 1-4, for example, the shelf 100 may have a spout 101 for the movement of containers 150 in and out. The gate 101 is oriented perpendicular to the extension of the first rail 111. The material port 101 may be located on one side of the shelf 100, or may be located on two opposite sides of the shelf 100. The reason why the orientation of the gate 101 is set to be perpendicular to the extending direction of the first rail 111 is to facilitate the arrangement of the first rail 111. By reasonably arranging the first rail 111 in the shelf stop area, the loading and unloading unit 140 is located beside the first rail 111, so that after the shelf 100 stops in the shelf stop area, the positioning between the shelf 100 and the shelf body 141 can be facilitated, and the goods loading and unloading operations can be more conveniently implemented. A reinforcing rod 104 is arranged between two adjacent upright posts 102 on the side of the shelf 100 where the material opening 101 is not arranged, and the reinforcing rod 104 is inclined to the upright posts 102 and is used for reinforcing the connecting structure of the upright posts 102 and the laminate 103.
Referring to fig. 1 and 3, the transfer robot needs to reserve a space for the upward and downward movement of the stocker 100 in the warehouse during the process of lifting up and lowering down the stocker 100, and reliably engages with the first rail 111 after the stocker 100 is lifted up by the transfer robot. To this end, the first rail 111 of the present invention may have a limiting portion. The stopper is located above the first slide member 112. During the movement of the rack 100 by the transfer robot, the first slide member 112 is closer to the stopper portion than when the rack 100 is placed on the floor. In other words, the distance between the first slide member 112 and the stopper portion decreases during the process of the carrier robot lifting up the rack 100. Accordingly, the first sliding member 112 is away from the stopper portion in a process in which the transfer robot does not move the rack 100, that is, the rack 100 is placed in the rack placing region.
With continued reference to fig. 1 and 3, further, in order to ensure that the rack 100 can be engaged with the second rail 121 when being jacked up by the transfer robot and can be reliably supported when the rack 100 is being set down by the transfer robot, the second rail 121 of the present invention may have a support portion for supporting the second sliding member 122. During the movement of the rack 100 by the transfer robot, the second slide member 122 is disengaged from the support portion. Accordingly, when the carrier robot does not move the rack 100, i.e., the rack 100 is put down by the carrier robot, the second slide member 122 may be pressed against the support portion. The support here may be configured as a floor of the warehouse.
The utility model discloses a with goods shelves 100 heightening to through increasing such as first track 111, second track 121, first sliding member 112 and the mode of second sliding member 122 isotructure, the upper portion of restriction goods shelves 100 takes place to rock the purpose on goods shelves 100's removal in-process upper portion, has improved the space utilization of warehouse along the direction of height, and has helped improving the storage capacity in warehouse. The increase in the height of the rack 100 can increase the storage capacity of the rack 100, and can store more goods, so that the probability of being hit during picking is relatively increased, thereby helping to reduce the number of robots used. By means of heightening the shelf 100 and adding auxiliary stabilizing structures such as the first rail 111 and the first sliding member 112 for preventing the upper part of the shelf 100 from shaking, the operation is more flexible and more convenient to implement compared with a multi-layer scheme with the same storage and the same efficiency. In addition, the quantity of the picking personnel or the mechanical arms can be reduced to a certain extent, and the labor is saved to a certain extent, so that the warehouse is more intelligent.
