Description

Technical Field

[0001] The present invention relates to industrial equipment, in particular to an industrial storage system. Background Art

[0002] During the storage and safekeeping of goods, they often need to be stacked to ensure that more goods can be placed within a limited storage space. Traditionally, stacking goods requires manual handling, which is subject to many limitations. Manual handling is difficult, and when goods are stacked high, handling efficiency is extremely low. With the development of modern logistics equipment, a variety of intelligent warehouses have emerged, such as stackers and shuttle garages. Shuttles, also known as rail-mounted automated guided vehicles, are equipment that emerged alongside automated logistics systems and high-bay warehouses. They can serve as peripheral equipment in high-bay warehouses, automatically connecting to other logistics systems such as inbound and outbound platforms, buffer platforms, conveyors, elevators, and robots. They can also serve as independent systems to carry out planned material handling.

[0003] The Chinese patent publication number is CN105858029A, and the patent name is an invention patent for an elevator for shuttle vehicles, which includes a frame part, a drive part, a counterweight part and a material box. The materials are placed on the elevator to achieve high-precision positioning and layer change, reducing the consumption of manpower and material resources. However, this elevator is not suitable for large warehouses with a large height. Every time this shuttle vehicle transports goods, it needs to transport back and forth from the bottom to the cargo placement location. When the goods are high, the intermediate path takes too long and the handling efficiency is low. In addition, the Chinese patent publication number is CN206969469U, and the patent name is the invention patent of shuttle material box composite elevator and shuttle garage, which includes a frame, a power system, a shuttle lifting unit and two conveyor roller lifting units arranged in parallel on both sides of the shuttle lifting unit. The frame has three lifting channels arranged in parallel, and the shuttle lifting unit and the two conveyor roller lifting units are respectively located in the three lifting channels. This composite elevator can ensure that when one conveyor roller lifting unit transports the material, the material can also be sent to another conveyor roller lifting unit through the shuttle, which can ensure the efficiency of transportation. However, this composite elevator is provided with three lifting channels, and each lifting channel is surrounded by columns, which takes up a large space. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an industrial warehousing system, which can improve the efficiency of cargo handling while ensuring that a small space is occupied, and shorten the time taken by a shuttle vehicle to complete a transport.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] An industrial storage system includes a three-dimensional warehouse and a shuttle material elevator arranged in the three-dimensional warehouse, wherein the shuttle material elevator includes:

[0007] A column arranged in the three-dimensional warehouse, wherein at least three sides of the column are longitudinally provided with lifting guide rails;

[0008] The material transfer device can move up and down along a lifting guide rail to transfer materials;

[0009] Two material lifting devices are respectively arranged on the lifting guide rails on both sides of the material transfer device, and are used to transfer goods to the material transfer device, or receive materials from the material transfer device and transport them to the corresponding floors of the warehouse.

[0010] Preferably, the material transfer device includes a transfer platform that can move up and down along a lifting guide rail, and a shuttle arranged on the transfer platform that can push materials laterally.

[0011] Preferably, the material lifting device includes a material transfer platform that can move up and down along the corresponding lifting guide rail, and a plurality of rollers are provided on the material transfer platform.

[0012] Preferably, a conveying mechanism corresponding to the lifting guide rail is provided at the end of the column, and the conveying mechanism includes a conveyor belt arranged along the lifting guide rail and a driving motor for driving the conveyor belt to move. The material transfer device and the material lifting device are respectively connected to the conveyor belt arranged on the corresponding lifting guide rail.

[0013] Preferably, the material transfer device is further provided with an anti-fall mechanism which can limit the movement of the material transfer device along the lifting guide rail when the conveyor belt is broken.

[0014] Preferably, the anti-fall mechanism includes a blocking member arranged in parallel with the lifting guide rail, and a locking structure that can be connected to the blocking member when the conveyor belt is broken.

[0015] Preferably, the blocking member is fixed on the column, and the blocking member is divided into multiple buffer channels by multiple hanging blocks.

[0016] Preferably, the locking structure includes a fixing seat and a pin shaft installed on the transfer platform, and a moving channel for the pin shaft to slide is provided in the fixing seat.

[0017] One end of the pin shaft is provided with a connecting piece that can be hung on the hanging block, and the other end is provided with a self-locking connecting rod fixedly connected to the transmission belt.

[0018] Preferably, the self-locking connecting rod is rotatably connected to the fixing seat via a rotating shaft.

[0019] One end of the self-locking connecting rod is fixedly connected to the transmission belt, and the other end is rotatably connected to the end of the pin shaft.

[0020] Preferably, the shuttle comprises a first drive structure and a second drive structure arranged front to back, and a placement area for placing materials to be transferred is provided between the first drive structure and the second drive structure.

[0021] The present invention achieves the following beneficial effects:

[0022] (1) An industrial storage system of the present invention is provided with a column including at least three sets of lifting rails and a material transfer device and a material lifting device corresponding to the lifting rails. A material lifting device transports the material to the material transfer device. After receiving the material, the material transfer device continues to transport it upward. When the material transfer device returns, it can complete the material transfer with another material lifting device. There is no need for the material transfer device to travel back and forth between the ground and the corresponding floor of the warehouse, which shortens the cargo transportation cycle and solves the problem that the existing industrial storage system only uses one set of lifting devices and has low efficiency in transferring cargo.

[0023] (2) An industrial storage system of the present invention is provided with a shuttle material elevator. The shuttle material elevator is provided with columns with lifting guide rails on at least three sides in the longitudinal direction, a material lifting device and a material transfer device. The material lifting device and the material transfer device are both arranged on the columns and connected to the lifting guide rails. There is no need to set the material lifting device and the material transfer device to be completely isolated and occupy a large space. This solves the problem that the existing shuttle system uses multiple lifting channels and uses guide rails and columns to enclose the multiple channels into a three-dimensional structure, which occupies a large space.

[0024] (3) An industrial storage system of the present invention includes a material transfer device, which is provided with an anti-falling mechanism including a blocking member and a locking structure. The locking structure is provided with a chamfer. The blocking member is divided into multiple moving channels by multiple hanging blocks. The hanging blocks are configured as wedge-shaped structures. When the elevator falls, the locking structure falls before it is fully popped out. It can only be stably engaged with the hanging block after it is fully popped out. This solves the problem that in the existing elevator self-locking structure, there is no chamfer between the locking structure and the blocking member during the falling process, and when the locking structure is not fully clamped, the elevator is at risk of continuing to fall.

[0025] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Similarly, terms such as "a" or "an" do not denote a limitation of quantity, but rather denote the presence of at least one.

[0046] like Figure 1 and 2As shown, as an embodiment of the present invention, an industrial storage system includes a three-dimensional warehouse and a shuttle material elevator 2. The shuttle material elevator includes a column 21, a material transfer device 22, and a material lifting device 23. The column 21 is provided with a lifting guide rail 211. The shuttle material elevator 2 is arranged inside the three-dimensional warehouse; the column 21 serves as the main structure of the shuttle elevator 2, and the lifting guide rails 211 are arranged on the side of the column. The lifting guide rails are arranged along the longitudinal direction of the column and are provided in at least three groups; the material transfer device is provided on the central lifting guide rail, and at least two material lifting devices are provided, arranged around the material transfer device. In this embodiment, there are three sets of lifting rails 211. Correspondingly, there is one material transfer device 22 and two material lifting devices 23. The material lifting devices 23 are arranged on the lifting rails 211 on both sides of the material transfer device 22. Both the material transfer device 22 and the material lifting device 23 can move up and down along the lifting rails 211. The lifting rails are independent of each other, and the material lifting devices and the material transfer device do not affect each other when they move up and down. The shuttle material elevator lifts the material and places it in the three-dimensional warehouse, which is used to store materials. As the main body of the shuttle material elevator, the height of the column should not be less than the height of the warehouse so that the shuttle material elevator can lift the material to any floor of the three-dimensional warehouse. The material transfer device moves up and down along the middle lifting rail to transfer materials. The material lifting device is used to transfer goods to the material transfer device or receive materials from the material transfer device and transport them to the corresponding floor of the warehouse. In this embodiment, the material is transferred upward along the lifting guide rails 211 by the material lifting device 23 to the material transfer device 22. After the material exchange is completed with the material transfer device, the material transfer device then transports the material to the corresponding floor of the warehouse. In this embodiment, the shuttle material elevator is equipped with one material transfer device and two material lifting devices. One of the material lifting devices transfers the material to the material transfer device. After receiving the material, the material transfer device continues to transport the material upward. When the material transfer device returns, it can complete the material transfer with the other material lifting device. This eliminates the need for the material transfer device to travel back and forth between the ground and the corresponding floor of the warehouse, shortening the cargo delivery cycle and resolving the problem of low cargo transfer efficiency in existing industrial warehousing systems that use only one set of lifting devices. The shuttle material elevator is equipped with columns with lifting guide rails on at least three sides in the longitudinal direction. The material lifting device and the material transfer device are both arranged on the columns and connected to the lifting guide rails. This eliminates the need for the material lifting device and the material transfer device to be completely isolated and occupy a large space. This solves the problem of existing shuttle systems that use multiple lifting channels and use guide rails and columns to enclose the multiple channels into a three-dimensional structure, which occupies a large space.

[0047] like Figure 3As shown, according to an embodiment of the present invention, the material transfer device 22 includes a transfer platform 221 and a shuttle 222. The rear portion of the transfer platform 221 is connected to the lifting guide rail 211 and moves up and down along the lifting guide rail. The shuttle 222 is placed on the transfer platform and can move up and down with the transfer platform. The shuttle can also move horizontally along the transfer platform to transport goods in the horizontal direction. The vertical movement is used to place the shuttle at the corresponding level of the three-dimensional warehouse. The vertical and horizontal movements of the shuttle cooperate with each other to transport materials to the corresponding location in the warehouse.

[0048] like Figure 4 As shown, according to an embodiment of the present invention, transfer platform 221 is further provided with roller unit 1 223. Roller unit 1 223 is located at the rear of the transfer platform and is connected to the central lifting rail 211. Roller unit 1 can be provided in multiple groups, arranged along the outer end surfaces of the lifting rail. Each roller of roller unit 1 is rotatably connected to the lifting rail. This not only secures the material transfer device in the vertical direction outside the lifting rail, but also reduces resistance when the material transfer device moves up and down along the lifting rail.

[0049] like Figure 5 As shown, according to an embodiment of the present invention, the material lifting device 23 includes a material transfer platform 231, and the material transfer platform is provided with rollers. The rollers are arranged in a plurality along the material transfer platform, and the material transfer platform can move up and down along the outer lifting guide rail. In this embodiment, the material is placed on the rollers of the material transfer platform, and the material moves upward along the lifting guide rail along the material lifting device to the height of the material transfer device. The material is transferred from the rollers to the material transfer device, and the rollers are arranged side by side in the horizontal direction of the material transfer platform so that the material can be transported smoothly. In this embodiment, similar to the material transfer device 22, the material transfer platforms 231 of the two material lifting devices 23 are also respectively provided with roller units 232 and roller units 3 233, which are respectively arranged along the outer end faces of their respective lifting guide rails to ensure that the material lifting devices can operate smoothly when moving up and down.

[0050] like Figure 6As shown, according to an embodiment of the present invention, a conveying mechanism 212 is provided at the end of a column 21. The conveying mechanism comprises a conveyor belt 213 and a drive motor 214. The conveyor belt 213 is arranged along the inner side of the lifting rail 211. The drive motor is connected to the conveyor belt and can be located at the base of the column or at the top of the column. In this embodiment, the drive motors are located at the bottom of the column, each with its own corresponding conveyor belt. In other embodiments, the drive motors can also be located at the top of the column to provide driving functions. The conveyor mechanisms 212 correspond to the lifting rail 211 and are arranged in three groups, each of which does not interfere with each other. The material transfer device and the material lifting device are both equipped with a transmission cavity. Each conveyor belt passes through the transmission cavity of the corresponding lifting rail to drive the material lifting device and the material transfer device. When transferring material, the drive motor drives the conveyor belt, which controls the material lifting device and the material transfer device. In this embodiment, the conveying mechanism is set up as three groups, and the material lifting device and the material transfer device can cooperate with each other to transfer goods, solving the problem of low transportation efficiency when using a single shuttle car elevator to transport materials from the ground to the corresponding level of the warehouse each time.

[0051] like Figure 7 As shown, according to an embodiment of the present invention, the material transfer device 22 is further provided with an anti-fall mechanism 224. The anti-fall mechanism is located at the rear end of the material transfer device 22 and is connected to the conveyor belt 213. The anti-fall mechanism can prevent the material transfer device from falling along the hoist rails in the event of a conveyor belt breakage. The anti-fall mechanism can be implemented as a speed limiter, a safety clamp, or a self-locking device. In this embodiment, the anti-fall mechanism is implemented as a self-locking device. When transporting light materials, compared to conventional hoists that use a speed limiter as the anti-fall mechanism, this avoids occupying a large installation space and reduces costs.

[0052] like Figure 7 As shown, according to an embodiment of the present invention, the anti-fall mechanism 224 includes a blocking member 225 and a locking structure 226. The blocking member 225 is arranged parallel to the lifting guide rail 211 and is positioned between the lifting guide rail and the conveyor belt. The locking structure 226 is disposed on the transfer platform 221 of the material transfer device 22, located at the rear of the transfer platform. If the conveyor belt breaks, the locking structure 226 deforms and extends toward the blocking member 225, connecting the blocking member and the locking structure, thereby preventing the material transfer device 22 from falling. The blocking member is approximately the same length as the lifting guide rail to ensure that the material lifting device will not fall rapidly at any height if the conveyor belt breaks.

[0053] like Figure 8As shown, according to an embodiment of the present invention, the blocking member 225 is fixed on the column, and a hanging block 227 is provided inside the blocking member. The hanging blocks are provided in plurality and adjacent hanging blocks are provided at intervals. The blocking member is divided into a plurality of buffer channels by the hanging blocks. When the conveyor belt breaks, the locking structure can perform a short buffering along the buffer channel so that the locking structure can be adjusted to an appropriate state to connect with the blocking member, thereby preventing the material transfer device from continuing to fall.

[0054] like Figure 9 and 10 As shown, according to an embodiment of the present invention, the locking structure 226 includes a fixed seat 228 and a pin 229. A movable channel is provided in the fixed seat, and a connecting member 2291 and a self-locking link 2292 are provided on the pin. The fixed seat and the pin are mounted on the transfer platform, and the pin can slide along the movable channel in the fixed seat. The connecting member is provided at one end of the pin, and the self-locking link is provided at the other end of the pin. When the conveyor belt breaks, the connecting member can be hooked to the hook block 227 of the blocking member 225 under certain conditions; the transmission cavity of the material transfer device is provided on the self-locking link, and the conveyor belt passes through the transmission cavity and is connected to the locking structure. The fixed seat 228 connects the locking structure and the material transfer device. When the conveyor belt breaks, the pin moves to connect to the blocking member to prevent the material transfer device from falling.

[0055] like Figure 10 and 11 As shown, according to an embodiment of the present invention, a rotating shaft 2293, a rotating cavity 2294, a transmission channel 2296 and a pin shaft mounting seat 2297 are provided on the self-locking link 2292, and a rotating pin 2295 is provided on the pin shaft 229. The rotating shaft 2293 divides the self-locking link into two parts, the upper part of the self-locking link is fixedly connected to the transmission belt, and the lower part is rotatably connected to the fixed seat around the rotating shaft. The rotating cavity 2294 is provided at the lower part of the self-locking link, and the pin shaft 229 is connected to the self-locking link through the rotating cavity. Figure 12As shown, one end of the pin 229 is flattened, and a rotating pin 2295 is disposed at the flat end of the pin. The rotating pin 2295 is placed in the rotating cavity 2294. A transmission channel 2296 is disposed on one side of the self-locking link 2292, and a transmission belt is disposed along the transmission channel. A pin mounting seat 2297 is disposed on the lower portion of the self-locking link. In this embodiment, the pin mounting seat 2297 is communicated with the rotating cavity 2294, that is, the flat end of the pin 229 is placed in the pin mounting seat 2297, and the rotating pin 2295 is placed in the rotating cavity 2294. In this embodiment, a spring member is sleeved on the pin 229. When the transmission belt is operating normally, the spring member is in a compressed state. When the transmission belt breaks, the spring member gradually deforms, driving the connecting member to move outward. In this embodiment, the rotating pin is smaller than the rotating cavity. When the conveyor belt breaks, the rotating pin can move along the rotating cavity 2294 to ensure that the pin shaft can extend outward. At the same time, since the pin shaft 229 is set in the moving channel of the fixed seat, the pin shaft can only move along the moving channel, and the locking structure can be stably hung on the blocking member 225.

[0056] like Figure 8 、 Figure 10 and Figure 12 As shown, according to an embodiment of the present invention, a chamfer 2298 and a stopper 2299 are provided on the connecting member 2291, the upper end of the hanging block 227 is set to a wedge shape, the chamfer is set on the outside of the connecting member, and the stopper is set on the inside of the connecting member. In this embodiment, the connecting member is set to an inner groove structure, and after the conveyor belt breaks, the groove is finally hung on the stopper. The stopper 2299 is preferably set to a circular block structure. When the conveyor belt breaks and the pin shaft extends outward to a certain extent, the stopper can abut against the stopper to prevent the pin shaft from over-extending and causing the connection between the connecting member and the stopper to be unstable. The stopper is set to a circular block structure. When the pin shaft moves outward to a certain extent, the circular structure can more effectively prevent the pin shaft from continuing to extend outward along the buffer channel. When the conveyor belt is intact, the self-locking connecting rod 2292 is fixed on the conveyor belt, the pin shaft will not be pushed out, and the pin shaft is against one side of the conveyor belt; when the conveyor belt is broken, the lower end of the self-locking connecting rod rotates around the rotating shaft, driving the pin shaft to extend outward, and at the same time the material transfer device 22 moves down a certain distance along the buffer channel to the adjacent hanging block 227. If the pin shaft extends outward enough, the connector is mounted on the wedge-shaped hanging block, and the material transfer device no longer falls; if the pin shaft does not extend outward enough, the chamfered connector slides down along one side of the wedge-shaped hanging block, and the material transfer device continues to move downward. When the pin shaft extends a distance enough for the connector to be hung on the hanging block, it stops falling. The combination of the chamfered connector and the wedge-shaped hanging block solves the problem that the existing elevator self-locking structure only uses conventional pin shafts and blocking members for engagement. When the pin shaft and the blocking member are only partially engaged, it can only temporarily fix the material transfer device, and there is still a risk of falling.

[0057] like Figure 13 As shown, according to an embodiment of the present invention, the shuttle 222 includes a first drive structure 2221 and a second drive structure 2222. The first drive structure and the second drive structure are located on the transfer platform in a front-to-back arrangement, and a placement area for placing materials to be transferred is provided between the first drive structure and the second drive structure.

[0058] like Figure 9 and 13 As shown, according to an embodiment of the present invention, roller units 4 2223 and 5 2224 are provided on either side of the first and second drive structures, respectively. Moving guide rails 2211 are provided on either side of the transfer platform 221 of the material transfer device 22. Roller units 4 and 5 are both configured to be in rolling connection with the moving guide rails. In this embodiment, roller units 4 and 5 each comprise two sets of rollers, one arranged transversely and the other longitudinally along the transfer platform. Accordingly, the moving guide rails are curved, with rollers oriented in different directions on each end of the rails. Using multiple sets of rollers can reduce resistance between the shuttle and the transfer platform.

[0059] According to an embodiment of the present invention, the shuttle 222 further includes a rotating shaft unit 2225. Both the first and second drive structures are equipped with synchronous transmission belts 2226 and folding shelves 2227. The rotating shaft unit is connected to the first and second drive structures via synchronous transmission belts 2226, which are connected to the lower ends of the folding shelves 2227. In this embodiment, a motor is installed within the first drive structure. When the shuttle is carrying a large amount of cargo and the storage area is insufficient, the motor enables the folding shelves 2227 on one side of the first drive structure to expand outward. Simultaneously, the rotating shaft unit 2225 causes the folding shelves on the second drive structure to expand outward, maintaining synchronization with the folding shelves on the first drive structure. This ability to expand outward ensures that the folding shelves can support large cargo.

[0060] According to an embodiment of the present invention, a lifting device is provided on the material transfer device, and the lifting device is provided on the shuttle and / or the transfer platform. The lifting device can be configured as a foldable structure or a rotating structure. In this embodiment, the lifting device is configured as a foldable structure. When the lifting device is not in use, it is placed in a folded state. After the material transfer device is transported to a corresponding height, the lifting device is unfolded to lift the material and then store the material. In other embodiments, the lifting device can also be configured as a rotating structure. When not in use, the main body of the lifting device is placed horizontally below the material. When the material is to be lifted, the lifting device is rotated to be placed vertically.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0062] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
