DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figures 1 to 10 As shown, the present invention provides an automated three-dimensional storage system for motor production, comprising a three-dimensional shelf 1 and a stacker 2. The three-dimensional shelf 1 comprises columns 31 and beams 3. The beams 3 are installed in multiple layers from bottom to top. The beams 3 enclose multiple cargo areas 12 on the columns 31. The stacker 2 is installed on the side of the three-dimensional shelf 1. The stacker 2 is used to store and retrieve goods in the cargo area 12 on the three-dimensional shelf 1. The goods are placed in the cargo area 12 through the pallet 11; A load-bearing rod 4 is installed on the crossbeam 3 in the cargo area 12. The length direction of the load-bearing rod 4 is the same as the length direction of the three-dimensional shelf 1. A limit rod 5 is installed on the load-bearing rod 4. A socket plate 51 is installed on the limit rod 5. The limit rod 5 is slidably installed on the load-bearing rod 4 through the socket plate 51. The limiting rods 5 are provided in multiple groups, each group of the limiting rods 5 is arranged in pairs, and a clamping spring 511 is installed between each group of the limiting rods 5. A blocking bolt 41 is installed on the carrying rod 4, and the blocking bolt 41 and the limiting rod 5 are connected to each other through a positioning spring 512. The clamping spring 511 and the positioning spring 512 are both installed on the socket plate 51; A contact plate 52 is mounted on the limiting rod 5, and an extrusion rod 53 is mounted on the lower surface of the contact plate 52. A through hole is formed on the limiting rod 5, and the lower end of the extrusion rod 53 is inserted into the through hole. A buffer pad 522 is mounted between the contact plate 52 and the limiting rod 5, and serrations are provided on the upper surface of the contact plate 52. The automated three-dimensional storage system includes a plurality of groups of three-dimensional shelves 1 and stackers 2, wherein the three-dimensional shelves 1 are evenly arranged in the warehouse, and aisles are formed between the three-dimensional shelves 1. The stackers 2 are installed in the aisles, and the stackers 2 are used to retrieve and store goods in the cargo areas 12 on the three-dimensional shelves 1 on both sides of the aisles. At the same time, the stacker 2 includes a lower track 21 laid on the ground, the lower track 21 is located in the aisle, and the lower track 21 has the same length direction as the three-dimensional shelves 1. A driving mechanism 22 and a lifting column 23 are installed on the lower track 21, and a telescopic plate fork 24 is installed on the lifting column 23. The lifting column 23 and the telescopic plate fork 24 are driven by the walking mechanism in the driving mechanism 22 to move along the lower track 21, and the telescopic plate fork 24 is driven by the lifting mechanism in the driving mechanism 22 to move up and down along the lifting column 23. During operation, the pallet 11 with the goods is lifted by the telescopic plate fork 24 on the stacker 2, and then the pallet 11 is moved to the corresponding goods area, and then the pallet 11 is placed in the goods area by the telescopic plate fork 24 to complete the storage of the goods; At the same time, when the pallet 11 carrying the goods is placed in the goods area, as the pallet 11 gradually descends, the foot block 111 on the lower surface of the pallet 11 will be inserted between the two limiting rods 5 of any group. Afterwards, when the pallet 11 is placed, the lower surface of the pallet 11 will contact the contact plate 52 on the limiting rod 5, and the lower surface of the foot block 111 will contact the upper surface of the carrying rod 4; Since the limiting rods 5 are slidably mounted on the carrying rods 4, and a clamping spring 511 is installed between the two limiting rods 5 arranged in pairs, when the pallet 11 is gradually lowered and placed in the cargo area 12, the foot block 111 on the pallet 11 will be inserted between the two limiting rods 5, and the two limiting rods 5 will be tightly attached to the two sides of the foot block 111 under the action of the clamping spring 511, clamping and limiting the foot block 111; At the same time, as the foot block 111 descends, the lower surface of the pallet 11 contacts and squeezes the contact plate 52, so that the pad between the contact plate 52 and the limiting rod 5 is squeezed and compressed, and then the contact plate 52 and the squeezing rod 53 move toward the direction close to the limiting rod 5, until the pallet 11 is placed. The lower end of the squeezing rod 53 contacts and squeezes the upper surface of the load-bearing rod 4, so that the position of the limiting rod 5 on the load-bearing rod 4 is locked by the squeezing rod 53, thereby limiting and locking the pallet 11 on which the goods are placed, and preventing the pallet 11 from moving in the length direction of the three-dimensional shelf 1 when the pallet 11 and the goods are affected or disturbed by external forces after the pallet 11 is placed in the cargo area 12, thereby affecting the stability of the goods placement and the safety of the storage system; At the same time, the positioning springs 512 connected to the blocking bolts 41 and the socket plates 51 fix the relative positions of the limiting rods 5 of each group on the carrying rods 4, thereby preventing the limiting rods 5 from shifting significantly after the cargo area 12 is repeatedly stored, retrieved, and placed. This would prevent the foot blocks 111 on the pallet 11 at the bottom of the cargo from being inserted between the limiting rods 5 after subsequent cargo is placed, and the foot blocks 111 from being limited and fixed by the limiting rods 5, thereby affecting the stability of the stored cargo. At the same time, after the goods are placed in the cargo area 12, the lower surface of the pallet 11 at the bottom of the goods will be pressed against the upper surface of the contact plate 52. The serrations on the upper surface of the contact plate 52 will make the pallet 11 and the contact plate 52 relatively fixed, so as to prevent the pallet 11 from moving in the width direction of the three-dimensional shelf 1 when the goods or the pallet 11 are affected by the outside world, and to prevent the goods and the pallet 11 from slipping, falling or protruding from the cargo area 12, which will affect the stability of the goods placement, interfere with the normal operation of the stacker 2, and cause safety accidents in the storage system.

[0019] As an embodiment of the present invention, the distance between the limit rods 5 in each group is less than or equal to the width of the foot block 111 on the support plate 11, the edge of the contact plate 52 in the length direction is beveled, and the bevel on the contact plate 52 contacts the foot block 111; The inclined surface is formed at the edge of the upper surface of the contact plate 52, and the inclined surface is used to guide and direct. When the foot block 111 moves downward and is squeezed onto the inclined surface, the squeezing force of the foot block 111 causes the two limit rods 5 to move away from each other, so that the foot block 111 is inserted between the two limit rods 5, thereby ensuring that after the subsequent goods are placed, the limit rod 5 fully limits the foot block 111 in the length direction of the three-dimensional shelf 1. At the same time, since the inclined surface is provided at the edge of the contact plate 52, the lower surface of the foot block 111 is prevented from directly abutting against the upper surface of the contact plate 52 during the descending process of the foot block 111, resulting in the foot block 111 and the support plate 11 being directly placed above the limit rod 5, so that the support plate 11 is not fully limited and fixed, affecting the stability of the goods placed in the cargo area 12 and the safety of the storage system. At the same time, since the distance between the limiting rods 5 is smaller than the width of the foot block 111, and the limiting rods 5 are connected to each other by the clamping spring 511, after the foot block 111 is inserted between the limiting rods 5, the limiting rods 5 will be tightly attached to the side of the foot block 111, avoiding as much as possible a large gap between the limiting rods 5 and the foot block 111, thereby ensuring a good limiting effect on the foot block 111 and the support plate 11.

[0020] As an embodiment of the present invention, a positioning bar 42 is installed on the upper surface of the carrying bar 4, and the lower end of the extrusion rod 53 is opposite to the upper surface of the positioning bar 42. The upper surface of the positioning bar 42 and the lower surface of the extrusion rod 53 are roughened, and the positioning bar 42 is elastic. When the contact plate 52 drives the squeezing rod 53 to move downward, the lower end of the squeezing rod 53 will contact and squeeze onto the positioning bar 42. The rough treatment of the lower surface of the squeezing rod 53 and the upper surface of the positioning bar 42 makes the friction between the squeezing rod 53 and the positioning bar 42 larger, avoiding sliding between the squeezing rod 53 and the positioning bar 42, affecting the positioning and fixation of the limiting rod 5 on the load-bearing rod 4, and affecting the limiting effect of the pallet 11. At the same time, after multiple storage and retrieval of goods in the same cargo area 12, the multiple contacts between the lower end of the squeezing rod 53 and the upper surface of the load-bearing rod 4 make it easy for the load-bearing rod 4 to slip. The upper surface of the extrusion rod 53 and the lower surface of the extrusion rod 53 are worn and smooth, which affects the limiting and fixing effect of the limit rod 5 on the load-bearing rod 4. Therefore, an elastic positioning strip 42 is installed on the load-bearing rod 4 to make the extrusion rod 53 and the positioning strip 42 contact each other. While ensuring that the friction between the extrusion rod 53 and the positioning strip 42 is relatively large, the wear of the extrusion rod 53 and the positioning strip 42 is avoided or reduced, affecting the limiting effect of the pallet 11 and the limiting effect of the limit rod 5 on the load-bearing rod 4, affecting the stability of the goods in the cargo area 12, and affecting the safety of the storage system.

[0021] As an embodiment of the present invention, limiting blocks 54 are installed on opposite sides of the limiting rod 5 in each group. The limiting blocks 54 are located at both ends of the limiting rod 5. The thickness of the limiting block 54 at the end facing the middle of the limiting rod 5 is smaller than that at the end facing away from the middle of the limiting rod 5. The upper surface of the limiting block 54 is inclined, and the inclined surface of the limiting block 54 and the inclined surface of the contact plate 52 are flush with each other and are in the same plane; Since there is a deviation in the position of the goods and the pallet 11, when the telescopic plate fork 24 on the stacker 2 is inserted under the pallet 11 and lifts the pallet 11 and the goods, the relative position of the goods and the pallet 11 on the telescopic plate fork 24 will also change, thereby causing a deviation in the placement position of the goods and the pallet 11 in the cargo area 12. For example, there is a position deviation in the width direction of the three-dimensional shelf 1, which causes the goods in the cargo area 12 to be placed too far forward or too far back, which easily causes uneven force on the local part of the three-dimensional shelf 1, affecting the normal use of the three-dimensional shelf 1. At the same time, when affected by external factors such as vibration, it is easy to cause the goods in the cargo area 12 to become unstable, slide out or fall, affecting the stability and safety of the goods placed in the cargo area 12; At the same time, limiting blocks 54 are installed at both ends of the limiting rods 5, so that when the foot block 111 is inserted downwardly between the limiting rods 5, when the position of the pallet 11 is too far forward or far back in the width direction of the three-dimensional shelf 1, the foot block 111 will be guided and guided by the side surfaces of the triangular or arc-shaped limiting blocks 54 in the vertical direction, so that the pallet 11 will move along the width direction of the three-dimensional shelf 1, and the pallet 11 on which the goods are placed is located in the middle position in the width direction of the three-dimensional shelf 1 in the cargo area 12 as much as possible, so that the local position of the three-dimensional shelf 1, that is, the cargo area 12, is evenly stressed, and the goods are prevented from being placed too far forward or too far back, resulting in instability after placement and easy sliding or interference with the normal operation of the stacker 2; At the same time, the upper surface of the limiting block 54 is inclined so that the upper surface of the limiting block 54 is an inclined surface, and the inclined surface of the limiting block 54 is flush with the inclined surface of the contact plate 52, and the two inclined surfaces are located in the same plane. Therefore, when the pallet 11 is placed too far forward or too far back in the cargo area 12, the foot block 111 will be guided and directed by the inclined surface of the limiting block 54, so as to avoid the foot block 111 being abutted by the limiting block 54, resulting in the foot block 111 being unable to be inserted between the limit rods 5, affecting the stability and safety of the cargo placement; At the same time, during the downward movement of the foot block 111, the lower surface of the pallet 11 just contacts the contact plate 52, and the pallet 11 will drive the contact plate 52 to continue moving downward. At this time, the weight of the goods and the pallet 11 is mainly borne by the telescopic fork plate on the stacker 2, so that when the foot block 111 contacts the vertical side of the triangular or arc-shaped limiting block 54 and is guided by it, the pallet 11 can move in the width direction of the three-dimensional shelf 1.

[0022] As an embodiment of the present invention, the limiting block 54 is made of elastic material, an extrusion cavity is defined inside the limiting block 54, and the extrusion cavity is filled with hydraulic oil. The buffer pad 522 is defined inside a receiving cavity, and the receiving cavity and the extrusion cavity are communicated with each other. When the pallet 11 is placed in the cargo area 12, the lower surface of the pallet 11 contacts and presses the contact plate 52, thereby driving the contact plate 52 to move downward, so that the buffer pad 522 between the contact plate 52 and the limit rod 5 is squeezed and compressed, and then the hydraulic oil in the accommodating cavity is squeezed into the extrusion cavity, causing the limit block 54 to gradually expand, further guiding and directing the foot block 111 that enters between the limit rods 5, so that the pallet 11 finally falls in the middle position of the cargo area 12, ensuring the stability and safety of the cargo placement; At the same time, after the limiting block 54 expands, the limiting block 54 will limit the movement of the foot block 111 in the width direction of the three-dimensional shelf 1, and cooperate with the serrations on the upper surface of the contact plate 52 to further ensure the stability of the pallet 11 in the cargo area 12, avoiding the movement of the goods and the pallet 11 in the width direction of the three-dimensional shelf 1, ensuring the stability of the goods, and ensuring the safety of the storage system.

[0023] As an embodiment of the present invention, a protruding rod 541 is provided on the side of the limiting block 54. The protruding rod 541 is evenly arranged on the side of the limiting block 54. The upper surface of the protruding rod 541 and the upper surface of the limiting block 54 are located in the same plane. After the foot block 111 is guided and led by the inclined surfaces on the limiting block 54 and the contact plate 52 into the space between the limiting rods 5, as the foot block 111 descends, the foot block 111 contacts the protruding rods 541 on the side of the limiting block 54, thereby reducing the contact area and friction between the foot block 111 and the limiting block 54, facilitating smooth downward movement of the foot block 111 until the pallet 11 is placed in the cargo area 12. At the same time, the wear or scratching of the surface of the limiting block 54 by the foot block 111 during the descent process is reduced, thereby minimizing damage to the limiting block 54 and leakage of the internal hydraulic oil. At the same time, through the raised rod 541 on the side of the limiting block 54, the movement of the foot block 111 in the width direction of the three-dimensional shelf 1 is restricted after the limiting block 54 expands, further limiting the pallet 11 and the foot block 111 in the width direction of the three-dimensional shelf 1, avoiding poor stability and safety of the goods and affecting the normal operation of the storage system.

[0024] As an embodiment of the present invention, an isolation layer 542 is installed on the inclined surface of the limiting block 54, and the isolation layer 542 is composed of elastic metal sheets arranged evenly, and the protruding rod 541 is an elastic metal rod; By installing an isolation layer 542 made of elastic metal sheets on the inclined surface of the limiting block 54, the foot block 111 is guided by the contact plate 52 and the inclined surface of the limiting block 54. When entering between the limiting rod 5, the foot block 111 can smoothly and quickly pass through the inclined surface area of ​​the limiting block 54, and the scraping and friction of the foot block 111 on the inclined surface of the limiting block 54 is reduced, thereby minimizing damage to the inclined surface of the limiting block 54 and affecting the normal use of the limiting block 54. At the same time, by installing a metal protruding rod 541 on the vertical side of the limiting block 54, the protruding rod 541 can avoid deformation and flattening when guiding the foot block 111, and the friction between the foot block 111 and the limiting block 54, and between the foot block 111 and the protruding rod 541 can be reduced as much as possible, thereby ensuring that the foot block can be smoothly inserted between the limit rods 5. At the same time, it can also avoid damage to the protruding rod 541, thereby ensuring the stability and safety of the goods in the cargo area 12.

[0025] As an embodiment of the present invention, a lubricating layer is installed on the lower surface of the limiting rod 5 and the surface of the socket plate 51 facing the load-bearing rod 4, and the lubricating layer is made of polytetrafluoroethylene material; Since the limit rod 5 is slidably installed on the load-bearing rod 4 through the socket plate 51, and as the storage system is used, a lubricating layer is installed on the surface of the limit rod 5 and the socket plate 51, so that when the limit rod 5 slides on the load-bearing rod 4, the limit rod 5 will not get stuck or jammed, ensuring that the goods are smoothly placed in the middle position in the cargo area 12, further ensuring the stability and safety of the goods.

[0026] The specific workflow is as follows: During operation, the pallet 11 with the goods is lifted by the telescopic plate fork 24 on the stacker 2, and then the pallet 11 is moved to the corresponding goods area, and then the pallet 11 is placed in the goods area by the telescopic plate fork 24 to complete the storage of the goods; At the same time, when the pallet 11 carrying the goods is placed in the goods area, as the pallet 11 gradually descends, the foot block 111 on the lower surface of the pallet 11 will be inserted between the two limiting rods 5 of any group. Afterwards, when the pallet 11 is placed, the lower surface of the pallet 11 will contact the contact plate 52 on the limiting rod 5, and the lower surface of the foot block 111 will contact the upper surface of the carrying rod 4; Since the limiting rods 5 are slidably mounted on the carrying rods 4, and a clamping spring 511 is installed between the two limiting rods 5 arranged in pairs, when the pallet 11 is gradually lowered and placed in the cargo area 12, the foot block 111 on the pallet 11 will be inserted between the two limiting rods 5, and the two limiting rods 5 will be tightly attached to the two sides of the foot block 111 under the action of the clamping spring 511, clamping and limiting the foot block 111; At the same time, as the foot block 111 descends, the lower surface of the support plate 11 contacts and presses the contact plate 52, so that the pad between the contact plate 52 and the limiting rod 5 is squeezed and compressed, and then the contact plate 52 and the squeezing rod 53 move toward the limiting rod 5 until the support plate 11 is placed and the lower end of the squeezing rod 53 contacts and presses on the upper surface of the carrying rod 4, so that the position of the limiting rod 5 on the carrying rod 4 is locked by the squeezing rod 53; At the same time, the relative position of each group of limiting rods 5 on the bearing rod 4 is fixed by the positioning spring 512 connected to the blocking bolt 41 and the socket plate 51; At the same time, after the goods are placed in the cargo area 12, the lower surface of the pallet 11 at the bottom of the goods will be pressed against the upper surface of the contact plate 52. The serrations on the upper surface of the contact plate 52 will fix the pallet 11 and the contact plate 52 relatively, preventing the pallet 11 from moving in the width direction of the three-dimensional shelf 1. By inverting an inclined surface at the edge of the upper surface of the contact plate 52, when the foot block 111 moves downward and is pressed against the inclined surface, the two limiting rods 5 are forced to move away from each other by the pressing force of the foot block 111, so that the foot block 111 is inserted between the two limiting rods 5. At the same time, it is prevented that the lower surface of the foot block 111 directly abuts against the upper surface of the contact plate 52 during the process of the foot block 111 descending, causing the foot block 111 and the support plate 11 to be directly placed above the limiting rods 5, so that the support plate 11 is not fully limited and fixed; At the same time, since the distance between the limiting rods 5 is smaller than the width of the foot block 111, and the limiting rods 5 are connected to each other by the clamping spring 511, when the foot block 111 is inserted between the limiting rods 5, the limiting rods 5 will be tightly attached to the side of the foot block 111; When the contact plate 52 drives the extrusion rod 53 to move downward, the lower end of the extrusion rod 53 contacts and is squeezed onto the positioning bar 42. The rough treatment of the lower surface of the extrusion rod 53 and the upper surface of the positioning bar 42 makes the friction between the extrusion rod 53 and the positioning bar 42 greater, thereby preventing the extrusion rod 53 and the positioning bar 42 from sliding. At the same time, an elastic positioning bar 42 is installed on the bearing rod 4 to make the extrusion rod 53 and the positioning bar 42 contact each other. While ensuring that the friction between the extrusion rod 53 and the positioning bar 42 is relatively large, the wear of the extrusion rod 53 and the positioning bar 42 is avoided or reduced. At the same time, limiting blocks 54 are installed at both ends of the limiting rods 5. Therefore, when the foot block 111 is inserted downwardly between the limiting rods 5, when the position of the pallet 11 is too far forward or too far back in the width direction of the three-dimensional shelf 1, the foot block 111 will be guided and guided by the side surfaces of the triangular or arc-shaped limiting blocks 54 in the vertical direction, so that the pallet 11 will move along the width direction of the three-dimensional shelf 1, and the pallet 11 on which the goods are placed will be located in the middle position of the width direction of the three-dimensional shelf 1 in the cargo area 12 as much as possible; At the same time, the upper surface of the limiting block 54 is inclined so that the upper surface of the limiting block 54 is an inclined surface, and the inclined surface on the limiting block 54 is flush with the inclined surface on the contact plate 52, and the two inclined surfaces are located in the same plane, so as to prevent the foot block 111 from being abutted by the limiting block 54, resulting in the foot block 111 being unable to be inserted between the limiting rods 5; At the same time, when the foot block 111 moves downward, the lower surface of the pallet 11 just contacts the contact plate 52, and the pallet 11 drives the contact plate 52 to continue to move downward. At this time, the weight of the goods and the pallet 11 is mainly borne by the telescopic fork plate on the stacker 2. Therefore, when the foot block 111 contacts the vertical side of the triangular or arc-shaped limiting block 54 and is guided by it, the pallet 11 can move in the width direction of the three-dimensional shelf 1. When the pallet 11 is placed in the cargo area 12, the lower surface of the pallet 11 contacts and presses the contact plate 52, thereby driving the contact plate 52 to move downward, so that the buffer pad 522 between the contact plate 52 and the limit rod 5 is squeezed and compressed, and then the hydraulic oil in the accommodating cavity is squeezed into the extrusion cavity, causing the limit block 54 to gradually expand, further guiding and directing the foot block 111 that enters between the limit rods 5, so that the pallet 11 finally falls in the middle position of the cargo area 12; At the same time, after the limiting block 54 expands, the limiting block 54 will limit the movement of the foot block 111 in the width direction of the three-dimensional shelf 1, and cooperate with the serrations on the upper surface of the contact plate 52 to further ensure the stability of the pallet 11 in the cargo area 12 and prevent it from moving in the width direction of the three-dimensional shelf 1; After the foot block 111 is guided and led by the inclined surfaces on the limiting block 54 and the contact plate 52 into the space between the limiting rods 5, as the foot block 111 descends, the foot block 111 contacts the protruding rods 541 on the side of the limiting block 54, thereby reducing the contact area and friction between the foot block 111 and the limiting block 54, facilitating smooth downward movement of the foot block 111 until the pallet 11 is placed in the cargo area 12. At the same time, the wear or scratching of the surface of the limiting block 54 by the foot block 111 during the descent process is reduced, thereby minimizing damage to the limiting block 54 and leakage of the internal hydraulic oil. At the same time, the protruding rod 541 on the side of the limiting block 54 limits the movement of the foot block 111 in the width direction of the three-dimensional shelf 1 after the limiting block 54 expands; By installing an isolation layer 542 made of elastic metal sheets on the inclined surface of the limiting block 54, the foot block 111 is guided by the contact plate 52 and the inclined surface of the limiting block 54. When entering between the limiting rod 5, the foot block 111 can smoothly and quickly pass through the inclined surface area of ​​the limiting block 54, and the scraping and friction of the foot block 111 on the inclined surface of the limiting block 54 is reduced, thereby minimizing damage to the inclined surface of the limiting block 54 and affecting the normal use of the limiting block 54. At the same time, by installing a metal protruding rod 541 on the vertical side of the limiting block 54, the protruding rod 541 is prevented from being deformed or flattened when guiding the foot block 111, and the friction between the foot block 111 and the limiting block 54, and between the foot block 111 and the protruding rod 541 is reduced as much as possible; Since the limit rod 5 is slidably installed on the load-bearing rod 4 through the socket plate 51, and as the storage system is used, a lubricating layer is installed on the surface of the limit rod 5 and the socket plate 51, so that when the limit rod 5 slides on the load-bearing rod 4, the limit rod 5 will not get stuck or jammed.
