Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a storage rack and a delivery device. Background Art

[0002] In photovoltaic glass production, a certain amount of photovoltaic glass needs to be palletized before it can be packaged. During the palletizing and packaging process, pallets are needed to support and secure the glass to facilitate its turnover.

[0003] In the related art, pallets are often manually transferred from the inventory area to the storage area using tools such as forklifts. When the glass needs to be packaged, the pallets are then transferred from the storage area to the packaging area. When stored, pallets need to be stacked in the storage area to increase the number of pallets that the storage area can accommodate. However, if the pallets are stacked too high, it will be inconvenient to transfer and there will be greater safety hazards; and if the pallets are stacked too low, the number of pallets transferred to the storage area will be small, resulting in an increase in the number of manual turnovers. In addition, when transferring pallets, it is necessary to manually separate the pallets stacked in the storage area before transferring them. The manual separation and transfer steps are cumbersome and inefficient, which reduces the packaging efficiency and packaging capacity of the glass. Utility Model Content

[0043] The storage rack 100 of the first embodiment of the present invention is described below with reference to the accompanying drawings. It should be noted that in the accompanying drawings, the up-down direction is the first direction, the left-right direction is the second direction, and the front-back direction is the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0044] The present invention provides a storage rack 100 for storing trays 200. Figure 1 、 Figure 3 and Figure 5As shown, the storage rack 100 includes a frame 110, a drive device 120, and a supporting assembly 130. The interior of the frame 110 defines a stacking space for storing pallets 200. The stacking space also includes an inlet and outlet 115 formed below the frame 110 along a first direction. The inlet and outlet 115 is used to transfer pallets 200 so that the pallets 200 can enter and exit the stacking space. The supporting assembly 130 is disposed in the stacking space and includes a connecting member 131 and a supporting member 132. The connecting member 131 is movably connected to the frame 110 and can move relative to the frame 110 in the first direction. Since the connecting member 131 and the supporting member 132 are connected, the supporting member 132 moves along with the connecting member 131. Furthermore, the supporting member 132 can also move relative to the connecting member 131 in a second direction under the influence of an external force, and the supporting member 132 has a first position and a second position under the influence of an external force. The support member 132 can be switched between the first position and the second position by being driven. Figure 3 As shown, the support member 132 is used to support the pallet 200 so that the pallet 200 is stored in the stacking space; when the support member 132 is in the second position, as shown in FIG. Figure 5 As shown, the support member 132 is used to avoid the pallet 200 so that the pallet 200 can leave the stacking space. The driving device 120 is connected to the frame 110 and the connecting member 131. The driving device 120 is used to drive the connecting member 131 to move relative to the frame 110 in a first direction so that the support member 132 moves closer to or away from the entrance 115 in the first direction.

[0045] Specifically, see Figures 1 to 7 As shown, the rack 110 includes a fence structure and a support structure. The support structure forms a three-dimensional structure (a structure with height in the first direction). The fence structure is connected to the support structure and is located on the side of the rack 110. The connection between the support structure and the fence structure creates a cavity within the rack 110, which serves as the stacking space. When storing and stacking pallets 200, the pallets 200 are transported from the entrance 115 to the stacking space, with the support members 132 in the second position. The connector 131 moves in the first direction toward the entrance 115, bringing the support members 132 closer to the entrance 115 until the support members 132 are at the bottom of the pallet 200. The support members 132 then transition from the second position to the first position, supporting the bottom of the pallet 200. The connector 131 then moves in the first direction, away from the entrance 115, moving the support members 132 away from the entrance 115, allowing the pallets 200 to be stored in the stacking space. When a new pallet 200 enters the entrance / exit 115 , the above-mentioned operation is repeated to achieve stacking of the pallets 200 .

[0046] When the pallet 200 needs to be separated for transfer, the device for transferring the pallet 200 will enter the stacking space through the entrance and exit 115 and be located below the pallet 200. At this time, the support member 132 is in the first position, and the pallet 200 is stored in the stacking space. When separating the pallets, the connecting member 131 and the support member 132 will move in the first direction (downward) relative to the frame 110 under the drive device 120, and will stop moving after moving to a certain distance. The support member 132 will then be converted from the first position to the second position, at which time the support member 132 will avoid the pallet 200, so that the bottom pallet 200 will be placed on the ground or on the device for transferring the pallet 200. The connecting member 131 and the supporting member 132 are then moved relative to the transfer device in a first direction (upward) by a distance equal to the height of the number of pallets 200 to be transferred. For example, if there are two pallets 200 to be transferred, the supporting member 132 is moved, counting from the bottom up, between the second and third pallets 200. The supporting member 132 is then shifted from the second position to the first position, supporting the bottom of the third pallet 200. This separates the pallets 200. The pallet 200 transfer device then supports the bottom of each pallet 200, completing the transfer of the pallets 200.

[0047] The storage rack 100 defines a stacking space through the frame 110, so that the pallets 200 can be accommodated in the stacking space, thereby improving the storage capacity of the pallets 200 by improving the utilization rate of the space. At the same time, since the movement speed of the connecting member 131 and the supporting member 132 is stable, the shaking of the pallets during the rising and falling process can be reduced. At the same time, since the frame 110 has a fence structure and a pillar structure, the frame 110 has a good bearing strength, and the stacking space of the frame 110 restricts the pallets 200, hindering the movement of the pallets 200 in the stacking space, further reducing the shaking of the stacked pallets 200, thereby solving the problem of the pallets 200 being stacked too high, which is inconvenient for transportation and poses a greater safety hazard; or the problem of the pallets 200 being stacked too low, resulting in a small number of pallets 200 and an increased number of manual turnover of the pallets 200. Furthermore, during conventional pallet sorting, manual sorting of the topmost pallet 200 is required to retrieve the pallet 200 that needs to be moved. Retrieving the pallet 200 that needs to be transferred from the bottom of the stacked pallets 200 may cause the stacked pallets 200 to collapse, posing a safety hazard. Therefore, it is necessary to retrieve the pallet 200 that needs to be transferred from the top of the stacked pallets 200. When retrieving the pallet 200, the device used to transfer the pallet 200 (such as a forklift) must be raised to a certain height before retrieving the pallet 200, resulting in low efficiency and cumbersome operation. The storage rack 100 of the present embodiment of the utility model can achieve pallet 200 sorting through the coordination and movement of the connector 131 and the support member 132, thereby improving the efficiency of pallet sorting and transfer, thereby enhancing packaging efficiency. Furthermore, the pallet 200 sorting is performed from below the rack 110, eliminating the need for a specific height requirement for the device that transfers the pallet 200, thus reducing the complexity of transfer. Furthermore, the tray 200 is separated from the bottom of the rack 110 rather than from the top of the stacked tray 200 , thereby reducing potential safety hazards and risks during the tray separation process.

[0048] In some embodiments, the stacking space has an opening 114 formed on one side of the frame 110 along the third direction. The opening 114 is suitable for pallets 200 to enter and exit the stacking space along the third direction. Specifically, the height of the opening 114 that allows pallets 200 to enter is greater than the height of the entrance 115. When stacking pallets 200, the pallets 200 can be transported into the stacking space one by one for stacking. For example, when pallets 200 need to be stacked, the pallets 200 are transported into the stacking space through the entrance 115, and the support member 132 is in the second position. If only one pallet 200 enters the stacking space, the connecting member 131 moves along the first direction toward the entrance 115, bringing the support member 132 closer to the entrance 115 until the support member 132 is at the bottom of the pallet 200. The support member 132 is then transferred from the second position to the first position so that the support member 132 supports the bottom of the pallet 200. The connecting member 131 is then moved in the first direction, away from the access port 115, so that the support member 132 is moved away from the access port 115, thereby storing the pallet 200 in the stacking space. When a new pallet 200 enters the access port 115, the support member 132 is moved in the first direction until the pallet 200 stored in the stacking space is placed above the new pallet 200. The support member 132 then shifts from the first position to the second position. The support member 132 is then moved in the first direction to the bottom of the new pallet 200, and then shifts from the second position to the first position, supporting the bottom of the lowest pallet 200 (i.e., the pallet 200 newly entered the stacking space). Finally, the support member 132 is moved again in the first direction, away from the access port 115, thereby collectively supporting all pallets 200 in the stacking space.

[0049] In other embodiments, if pallets 200 have already been stacked outside the stacking space, the stack (i.e., the stacked pallets 200) needs to be placed in the stacking space. Because the height of the stack is greater than the space of the entrance / exit 115, the stack needs to be placed through the opening 114 into the stacking space. Support members 132 are then used to support the bottommost pallet 200 in the stack, thereby storing the entire stack in the stacking space. Similarly, if, during a pallet separation operation, for example, only one pallet 200 needs to be transferred, support member 132 is moved, counting from bottom to top, between the first and second pallets 200. Support member 132 is then shifted from the second position to the first position, supporting the bottom of the second pallet 200. Support member 132 is then moved in the first direction, away from the entrance / exit 115, to support the remaining pallets 200, thereby separating the pallets 200. The pallet 200 transfer mechanism then supports the bottom of each pallet 200, thereby transferring the pallets 200. If the height of the separated pallets 200 is greater than the height of the access opening 115 , the stack of separated pallets 200 needs to be transferred out of the stacking space through the opening 114 .

[0050] In some embodiments, see Figure 3 、 Figure 4 and Figure 6 As shown, the storage rack 100 also includes a movable member 140, which includes a fixed portion 141 and a first movable portion 142 connected to each other. The fixed portion 141 is connected and fixed to the side of the connecting member 131 facing the support member 132, and the first movable portion 142 is connected to the support member 132. The first movable portion 142 is used to drive the support member 132 to move along the second direction relative to the connecting member 131. Specifically, in this embodiment, the first movable portion 142 is driven by a cylinder to enable the support member 132 to move. The use of the cylinder can provide the first movable portion 142 with a certain travel distance to prevent the support member 132 from colliding with the fixed portion 141 and causing damage when the support member 132 follows the first movable portion 142 to retract. In other embodiments, the first movable portion 142 can also drive the support member 132 to move by a chain drive or a belt drive. The movable part 140 includes a supporting portion 143, which is connected to the first movable part 142. The support part 132 extends along the first direction to form a protrusion 1321, and the protrusion 1321 is connected to the supporting portion 143. Along the second direction, the supporting portion 143 is arranged between the first movable part 142 and the protrusion 1321. The first movable part 142 is connected to the support part 132 through the supporting portion 143 to drive the support part 132 to move. Through the supporting portion 143, the first movable part 142 can be detachably connected to the support part 132. When the support part 132 is damaged, the support part 132 can be replaced alone without replacing the movable part 140 and the support part 132 together. In other embodiments, the movable part 140 may also not include the supporting portion 143, and the support part 132 is fixedly connected to the first movable part 142.

[0051] In some embodiments, see Figure 3 and Figure 5As shown, the connector 131 has a hollow structure 1311 that extends through the connector 131 along a first direction. Specifically, in this embodiment, there is only one connector 131. The connector 131 is connected to both sides of the frame 110 so that when the support member 132 supports the pallet 200, the connector 131 can partially relieve the pressure of the pallet 200 from the support member 132, thereby increasing the support strength of the support member 132. However, to allow the pallet 200 to enter and exit the stacking space, the hollow structure 1311 is required in the connector 131. The dimensions of the hollow structure 1311 must be no smaller than the dimensions of the pallet 200. When the support member 132 is in the first position, at least a portion of the support member 132 aligns with the hollow structure 1311 along the first direction. That is, when the support member 132 is in the first position, a portion of the support member 132 extends into the hollow structure 1311 to support the pallet 200 and prevent the pallet 200 from escaping the stacking space through the hollow structure 1311.

[0052] In some embodiments, see Figures 1 to 5 As shown, the load-bearing assembly 130 includes at least two support members 132. The frame 110 has a first side 111 and a second side 112 along the second direction. The first side 111 and the second side 112 are arranged opposite to each other, and the first side 111 and the second side 112 are respectively connected to the support members 132. The support members 132 respectively support the pallet 200 on the first side 111 and the second side 112 to improve the support strength. Specifically, in one embodiment, there are two support members 132, and the two support members 132 are respectively located on the first side 111 and the second side 112. When it is necessary to support the pallet 200, the two support members 132 move along the second direction, and the movement directions of the two support members 132 are opposite, that is, the support members 132 arranged on the first side 111 and the second side 112 extend toward the interior of the stacking space to jointly support the pallet 200. At this time, the support members 132 are in the first position. When it is necessary to avoid the pallet 200, the moving directions of the two support members 132 are opposite to each other, that is, the support member 132 arranged on the first side 111 and the support member 132 on the second side 112 are respectively retracted toward the inside away from the stacking space to jointly avoid the pallet 200 so that the pallet 200 can be transferred out of the stacking space. At this time, the support member 132 is in the second position.

[0053] In some embodiments, the supporting assembly 130 may include only one support member 132. For example, the support member 132 has a first end and a second end relative to each other, the first end being connected to the first side 111, and the support member 132 can be extended and retracted in a second direction relative to the first side 111. When it is necessary to support the tray 200, the support member 132 moves toward the second side 112 of the rack 110, and the first end slides on the first side 111 until the second end abuts the second side 112 to reach the first position. When it is necessary to avoid the tray 200, the support member 132 moves away from the second side 112 of the rack 110, and the first end slides on the first side 111, causing the second end to retract to the first side 111 of the rack 110 to reach the second position.

[0054] In other embodiments, the number of connecting members 131 can be two or more. For example, there are two connecting members 131, each connected to one side of the frame 110, and there are also two supporting members 132. The supporting members 132 are each connected to the connecting members 131, and the two connecting members 131 are not connected. This also allows the supporting members 132 to slide relative to the connecting members 131 in the second direction.

[0055] In some embodiments, see Figure 1 As shown, the drive device 120 further includes a second movable portion 121, a driving member 122, and a transmission wheel 123. Specifically, the second movable portion 121 can be moved relative to the frame 110 in a first direction under external force to change the height of the tray 200 in the first direction. Without external force, the second movable portion 121 remains stationary relative to the frame 110, ensuring that the tray 200 is stably stored in the stacking space. The transmission wheel 123 is connected to the frame 110 and can move relative to the frame 110. The transmission wheel 123 is driven by the driving member 122 to move. At the same time, the transmission wheel 123 is also connected to the second movable part 121, and the driving member 122 drives the second movable part 121 through the transmission wheel 123. Since the connecting member 131 connects the second movable part 121 and the frame 110, when the second movable part 121 moves relative to the frame 110 along the first direction, the connecting member 131 will also follow the second movable part 121 to move relative to the frame 110 along the first direction.

[0056] In some embodiments, see Figure 1As shown, in the first direction, the driving member 122 is disposed on the upper side of the frame 110. The driving member 122 is disposed relative to the connecting member 131 and the supporting member 132, that is, in the first direction, the connecting member 131 and the supporting member 132 are disposed on the lower side of the frame 110. Because the separation and transfer of the pallets 200 are performed on the lower side of the frame 110, the driving member 122 is disposed relative to the connecting member 131 and the supporting member 132. This allows the driving member 122 to normally drive the connecting member 131 and the supporting member 132 without hindering the separation and transfer of the pallets 200. This prevents the positioning of the driving member 122 from affecting the separation and transfer process and reducing work efficiency.

[0057] In some embodiments, see Figure 1 As shown, both the first side 111 and the second side 112 are provided with a second movable portion 121. The drive device 120 further includes a commutator 124 connected to the second movable portions 121 on the first side 111 and the second side 112. Specifically, the storage rack 100 improves the movement efficiency of the support member 132 and the connecting member 131 by providing the second movable portion 121 on both the first side 111 and the second side 112. In this embodiment, there is only one drive member 122, which drives the second movable portion 121 on the first side 111 and the second side 112 to move in the first direction. Because the driving member 122 has a single movement direction when rotating, it cannot cause the second movable portions 121 on the first side 111 and the second side 112 to move in the same direction (either upward or downward). Therefore, the driving member 122 is connected to the second movable portion 121 on the first side 111 or the second side 112 via a commutator 124 to ensure that the second movable portions 121 on the first side 111 and the second side 112 have the same movement direction. In other embodiments, the driving device 120 may not include the commutator 124, and at least two driving members 122 may be provided to drive the second movable portions 121 on the first side 111 and the second movable portions 121 on the second side 112, respectively. This can also ensure that the second movable portions 121 on the first side 111 and the second movable portions 121 on the second side 112 have the same movement direction.

[0058] The following describes the delivery device 10 of the second embodiment of the present invention with reference to the accompanying drawings. Figures 1 to 7 As shown, the delivery device 10 includes a storage rack 100 and a transfer device as described in any of the above embodiments. The transfer device is in communication with the storage rack 100 and has a support surface. When the transfer device enters the stacking space of the storage rack 100, the storage rack 100 senses the transfer device and drives the support assembly 130 to perform a pallet separation operation, placing the pallet 200 to be transferred onto the support surface, thereby putting the pallet 200 into operation.

[0059] Specifically, in the initial state, the support member 132 is in the first position to support the pallets 200 for storage in the stacking space. When the transfer device enters the stacking space through the entrance and exit 115, the storage rack 100 will receive a signal that the transfer device has entered the stacking space. There is a spacing distance between the carrying component 130 and the ground, and the transfer device will stay in this spacing distance. At this time, the connecting member 131 and the support member 132 move relative to the transfer device in the first direction (downward) so that the pallet 200 at the bottom of the first direction contacts the transfer device. The support member 132 is then converted from the first position to the second position, thereby carrying all the pallets 200 on the transfer device. Subsequently, the connecting member 131 and the support member 132 are moved relative to the transfer device in the first direction (upward), and the distance moved is the number of pallets 200 that need to be transferred. In this embodiment, the distance moved is the height of one pallet 200. Since there is a distance H between the pallets 200, after the connecting member 131 and the supporting member 132 have been moved, the supporting member 132 is moved from the second position to the first position so that the supporting member 132 is inserted into the distance H between the pallets 200. At this time, the pallets 200 not supported by the supporting member 132 are placed on the supporting surface, and the transfer device moves to transfer the pallets 200.

[0060] The delivery device 10 of the present embodiment cooperates with the storage rack 100 and the transfer device to enable the storage rack 100 to switch between a first position and a second position to separate the stacked pallets 200, and to place the pallets 200 to be transferred on the support surface of the transfer device for transfer. This improves the convenience of transferring the pallets 200, increases transfer efficiency, and saves labor.

[0061] In some embodiments, see Figure 7 As shown, the delivery device 10 also includes a sensing device 300, which is connected to the frame 110 and is located at the bottom of the frame 110. Specifically, the sensing device 300 is set at the position of the inlet and outlet 115. In other embodiments, the sensing device 300 can be located at other positions of the frame 110, as long as the transfer device can be identified. The sensing device 300 identifies the transfer device through infrared sensing or image recognition. When the transfer device enters the stacking space through the inlet and outlet 115, the sensing device 300 will detect the entry of the transfer device, thereby sending a signal to the processor that controls the storage rack 100. The processor will receive the signal and control the connector 131 and the support 132 to work, so as to separate the pallets 200 so that the pallets 200 that need to be transferred are placed on the support surface.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
