Description

Technical Field

[0001] The utility model belongs to the technical field of stereoscopic warehouses, and particularly relates to a stereoscopic warehouse system for storing the discharged rubber of a mixer for building stacks. Background Art

[0002] In the tire production industry, as the core link of rubber material processing, the logistics efficiency of the mixing workshop is directly related to the smoothness and efficiency of the entire production line. With the expansion of production scale, many challenges have gradually emerged in the existing logistics system.

[0003] Currently, the mixing workshop generally relies on AGV vehicles for the inbound and outbound operations of rubber compounds. This mode effectively promoted the improvement of logistics efficiency in the initial stage. However, with the increasing production demand, the transportation capacity bottleneck of the AGV system has become more and more obvious. Especially in the remote areas of the workshop, due to the long transportation route, the operation efficiency of AGVs has been significantly reduced, affecting the overall logistics efficiency.

[0004] In addition, inventory management problems have become increasingly prominent. The continuous increase in production volume has increased the inventory pressure, and problems such as warehouse explosions and poor turnover occur frequently. The single-layer flat warehouse positions in the workshop can no longer meet the rapidly growing demand for warehouse positions.

[0005] More critically, due to the limitations of the space design of old workshops, large automated stereoscopic warehouses cannot be directly introduced to optimize the logistics system. This makes the traditional logistics mode seem powerless in coping with the requirements of high-efficiency and high-volume production.

[0006] To sum up, the existing logistics system in the mixing workshop faces multiple challenges such as limited transportation capacity, insufficient warehouse positions, and increased risk of AGV failures, which severely restricts the further improvement of production efficiency and production capacity. Based on this, the existing technology needs to be further developed. Summary of the Utility Model

[0030] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model will be clearly and completely described below in conjunction with the attached drawings of the present utility model. Based on the embodiments in this application, other similar embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "upper", "lower", "left", "right", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for illustration rather than limitation of the present invention.

[0031] The present utility model will be further described below in conjunction with the attached drawings and preferred embodiments.

[0032] According to an embodiment of the present utility model, a vertical storage system for storing the discharged rubber of a mixer for building stacks is provided. Please refer to Figures 1 to 4 , including: a glue storage roller bed 1, the glue storage roller bed 1 having at least two layers; a lifting and traveling device 2, the lifting and traveling device 2 including: a roller bed conveying mechanism 23, the roller bed conveying mechanism 23 being used to receive the rubber stack output from the building stack and transfer it to the glue storage roller bed 1; a traveling mechanism 25, the traveling mechanism 25 being connected to the roller bed conveying mechanism 23 and driving the roller bed conveying mechanism 23 to reciprocate between the building stack and the glue storage roller bed 1; a lifting mechanism (not shown in the figure), the lifting mechanism being connected to the roller bed conveying mechanism 23 and driving the roller bed conveying mechanism 23 to reciprocate in the vertical direction so that the roller bed conveying mechanism 23 is docked with different layers of the glue storage roller bed 1.

[0033] It should be noted that the vertical storage system for storing the discharged rubber of a mixer for building stacks is arranged beside the building stack. The rubber stack output from the building stack is transported to the glue storage roller bed 1 through the lifting and traveling device 2. The lifting and traveling device 2 can replace or partially replace the role of the AGV cart in the operation of rubber material in and out of the warehouse, reduce the pressure of AGV logistics operation, and significantly improve the stability and reliability of logistics transportation.

[0034] In the vertical storage system for storing the extruded rubber bales from the internal mixer stacking operation in this embodiment, the lifting and traveling device 2 further includes a frame 21. The frame 21 is arranged around the roller bed conveying mechanism 23 to form a channel for the roller bed conveying mechanism 23 to lift. A guide rod 22 is fixedly provided on the frame 21. The guide rod 22 is arranged in the vertical direction. A guide wheel 231 is connected to the side of the roller bed conveying mechanism 23. A card slot matching the guide rod 22 is provided on the guide wheel 231. When the roller bed conveying mechanism 23 moves up and down, the guide wheel 231 rolls along the guide rod 22.

[0035] It should be noted that the cooperation between the guide rod 22 and the guide wheel 231 ensures the stability of the roller bed conveying mechanism 23 when moving in the vertical direction and prevents the rubber bales from tipping over when the roller bed conveying mechanism 23 moves up and down.

[0036] Specifically, a plurality of guide rods 22 are provided. The plurality of guide rods 22 are symmetrically arranged. The guide wheels 231 are arranged in one-to-one correspondence with the guide rods 22, further ensuring the stability of the roller bed conveying mechanism 23 when moving in the vertical direction.

[0037] Preferably, in order to prevent the frame 21 from interfering with the output of the rubber bales, a channel for the output of the rubber bales is provided on one side of the frame 21 close to the discharge end of the roller bed conveying mechanism 23.

[0038] In the vertical storage system for storing the extruded rubber bales from the internal mixer stacking operation in this embodiment, the roller bed conveying mechanism 23 includes: a plurality of rollers 232, which are drivingly connected; a roller bed conveying drive motor 233, and the output end of the roller bed conveying drive motor 233 is connected to one of the plurality of rollers 232 to drive the roller 232 to rotate. Specifically, the plurality of rollers are drivingly connected by a chain.

[0039] In the vertical storage system for storing the extruded rubber bales from the internal mixer stacking operation in this embodiment, the lifting mechanism includes: a lifting drive motor, which is fixedly provided on the top of the frame 21; a sprocket and chain transmission assembly, and the output end of the lifting drive motor is connected to the roller bed conveying mechanism 23 through the sprocket and chain transmission assembly. Through sprocket and chain transmission, the roller bed conveying mechanism 23 is driven to move up and down.

[0040] It should be noted that the specific form of the sprocket and chain transmission assembly is not limited here, as long as the lifting of the roller bed conveying mechanism 23 can be realized.

[0041] In the vertical storage system for storing the extruded rubber bales from the internal mixer stacking operation in this embodiment, the lifting and traveling device 2 further includes a guide rail 24. The guide rail 24 extends from the discharge end of the stacking operation to the feed end of the vertical storage. The traveling mechanism 25 moves along the guide rail 24 to drive the entire lifting and traveling device 2 to make a reciprocating motion directly between the stacking operation and the rubber storage roller bed 1.

[0042] In the vertical storage system for storing the extruded rubber bales from the internal mixer in this embodiment, the traveling mechanism 25 includes a plurality of rollers 251, and all the plurality of rollers 251 are connected to the frame 21. When the roller bed conveying mechanism 23 makes a reciprocating movement between stacking operations, the rollers 251 roll along the guide rail 24. At least two of the plurality of rollers 251 are driving wheels, and the two driving wheels are connected by a driving shaft 252; the traveling mechanism 25 further includes a traveling driving motor (not shown in the figure), and the output end of the traveling driving motor is in transmission connection with the driving shaft 252 to urge the driving wheels to move along the guide rail 24.

[0043] In the vertical storage system for storing the extruded rubber bales from the internal mixer in this embodiment, the rubber storage roller bed 1 includes a plurality of free rollers, and the plurality of free rollers are arranged at intervals in sequence. The height of the discharge end of the rubber storage roller bed 1 is lower than the height of the feed end of the rubber storage roller bed 1, so that the rubber bale can directly travel from the feed end of the rubber storage roller bed 1 to the discharge end of the rubber storage roller bed 1 by its own weight without power drive, reducing the operation cost of the vertical storage system for storing the extruded rubber bales from the internal mixer.

[0044] Preferably, the slope of the rubber storage roller bed 1 is set to be 0.4° - 2°, and the slope of the rubber storage roller bed 1 is selected according to its length. The longer the rubber storage roller bed 1 is, the smaller the slope is, to prevent the speed of the rubber bale from being too high when it travels to the discharge end of the rubber storage roller bed 1, causing too much impact on the rubber storage roller bed 1 or causing the rubber bale to fall over.

[0045] Specifically, a limit stop block 11 is provided at the discharge end of the rubber storage roller bed 1 to prevent the rubber bale from rushing out of the rubber storage roller bed 1.

[0046] In some specific embodiments, the rubber storage roller bed 1 includes free rollers, roller bed side plates for installing the free rollers, and roller bed legs for supporting the rubber storage roller bed 1.

[0047] In the vertical storage system for storing the extruded rubber bales from the internal mixer in this embodiment, it further includes a rubber discharge roller bed 3. The running direction of the rubber discharge roller bed 3 is the same as the rubber discharge direction of the stacking. The lifting and traveling device 2 is located between the stacking and the rubber discharge roller bed 3. When the rubber bale does not need to be stored in the vertical storage, the roller bed conveying mechanism 23 receives the rubber bale output from the stacking and directly outputs the rubber bale to the rubber discharge roller bed 3.

[0048] Preferably, the rubber discharge roller bed 3 is inclined, the height of the discharge end of the rubber discharge roller bed 3 is lower than the height of the feed end of the rubber discharge roller bed 3, and power-free rollers are installed on the rubber discharge roller bed 3, so that the rubber bale can directly travel from the feed end of the rubber discharge roller bed 3 to the discharge end of the rubber discharge roller bed 3 by its own weight without power drive.

[0049] For the convenience of understanding the present invention, the present invention is further described below with the aid of the running route of the rubber bale (assuming that the rubber storage roller bed 1 has two layers):

[0050] When the rubber stack does not need to be stored in the rubber storage roller bed 1, the rubber stack discharged from the stacking process passes through the lifting and traveling device 2. Due to the continuous operation of the roller bed conveying mechanism 23, the rubber stack is directly discharged to the rubber discharging roller bed 3, and then transported away by the AGV cart.

[0051] When the rubber stack needs to enter the first-layer rubber storage roller bed 1, the rubber stack discharged from the stacking process enters the lifting and traveling device 2. Then, the roller bed conveying mechanism 23 stops running, and the traveling mechanism 25 runs, carrying the rubber stack along the guide rail 24 to the feeding end of the rubber storage roller bed 1. Subsequently, the roller bed conveying mechanism 23 runs, discharging the rubber stack to the first-layer rubber storage roller bed 1, and the rubber stack is transported to the discharging end of the rubber storage roller bed 1 due to its own weight.

[0052] When the rubber stack needs to enter the second-layer rubber storage roller bed 1, the rubber stack discharged from the stacking process enters the lifting and traveling device 2. Then, the roller bed conveying mechanism 23 stops running, and the traveling device of the lifting and traveling device 2 runs, carrying the rubber stack along the guide rail 24 to the feeding end of the rubber storage roller bed 1. The lifting mechanism runs, lifting the rubber stack to the feeding end of the second-layer rubber storage roller bed 1. Then, the roller bed conveying mechanism 23 runs, discharging the rubber stack to the second-layer rubber storage roller bed 1, and the rubber stack is transported to the discharging end of the rubber storage roller bed 1 due to its own weight.

[0053] It should be noted that the rubber storage roller bed 1 is not limited to 2 layers and can be set to multiple layers according to the on-site storage space. The operation logic of the multiple-layer rubber storage roller bed 1 is the same as that described above.

[0054] The above has made a detailed description of the present utility model. The above is only the preferred embodiment of the present utility model, and it cannot limit the scope of implementation of the present utility model. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present utility model.
