Description

Technical Field

[0001] The invention belongs to the technical field of material storage and transportation, and in particular relates to a cargo stacker for storage and transportation. Background Art

[0002] In the field of logistics, warehousing and transportation mainly involves the centralized storage of goods on a three-dimensional rack structure. In the limited space of a warehouse plant, by increasing the height of the goods transportation and stacking them layer by layer, the maximum utilization of the storage material transportation is achieved. For the transportation of goods on the three-dimensional racks, a cargo stacker is usually used to store or load and unload the goods. The stacker is generally provided with three axes, i.e., tracks for the movement of the device, which are placed along both sides of the rack, so that the stacker transport trolley can move back and forth along the track surface, and then the transport trolley can also be lifted and lowered to lift the goods to a specified height. A platform is also provided on the top of the transport trolley, which moves back and forth vertically on both sides along the transport direction of the device track, and the goods placed above the platform (generally, a loading board with space on the side is provided) are placed on the rack. In the prior art, when the transport trolley is The platform of the vehicle extends outward and places the goods on the designated position of the rack. Generally, the entire transport trolley moves downward in the vertical direction for a short distance (the purpose is to separate the platform from the support for the goods from below, so that the rack can support the goods, and at the same time, it is convenient to recycle the platform to the transport trolley). However, this part of the movement generally requires the motor that drives the transport trolley to perform redundant movements. When the transport trolley is displaced vertically as a whole, the burden of the lifting motor that drives its movement is additionally increased, and the displacement stroke of the transport trolley in this process is small, but it is subjected to accelerated motion, uniform motion (or even no motion due to the small distance), and decelerated motion until it stops in a short period of time. This brings a counter-torque burden to the lifting motor, thereby damaging the internal structure of the motor and reducing the service life of the device. Therefore, it is urgent to solve this problem. Summary of the invention

[0005] As a preferred solution of the present invention, the slide rails are arranged in two groups and are distributed on the top of the fixed platform, one on the left and one on the right. The slide bar is slidably installed on the upper surface of the slide rails. The top of the slide bar is fixedly connected to the bottom of the moving seat. The driving mechanism is used to drive the slide bar and the moving seat to move.

[0006] As a preferred solution of the present invention, the driving mechanism includes two groups of motors 1 distributed front and back, the output shaft of the motor 1 is fixedly installed with a gear 1, the right side of the slide bar on the right side is fixedly connected with a rack, and the gear 1 is meshed with the rack.

[0007] As a preferred solution of the present invention, the through groove is located in the middle of the bottom surface of the moving seat and penetrates upward to the inner wall of the placement cavity, and the abutment tube 1 and the abutment tube 2 can enter the through groove.

[0008] As a preferred solution of the present invention, the rotating drum and the worm are arranged one above the other and perpendicular to each other, and the output shaft of the second motor is fixedly connected to the worm.

[0009] As a preferred solution of the present invention, the outer surface of the abutting tube 2 abuts against the top of the fixing platform, and the inner wall of the sliding groove is designed to be an arc.

[0010] As a preferred solution of the present invention, the upper surface of the support platform is larger than the upper surface of the card block, and a gap is provided between the bottom of the card block and the bottom of the placement cavity.

[0011] As a preferred solution of the present invention, the highest points of the outer surfaces of the abutment tubes 1 and 2 are lower than the top of the inner wall of the through groove, and each group of the connecting columns is provided with two left and right ones, and are fixedly connected to the two ends of the outer surface of the rotating cylinder.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The stacker has been redesigned to reduce the extra descending action of the device after loading goods in the rack area, reduce the counter-torque burden of the lifting vehicle, and provide a slide rail and a slide bar so that the moving seat can drive the card block and the support platform to move along the surface of the slide rail under the action of the driving mechanism perpendicular to the track 1 to load and unload materials, wherein the card block and the support platform constitute a feeding platform for holding goods or unloading materials, and a guide column is provided to be inserted into the inside of the card block so that the card block can only move up and down, and then a through groove is opened at the bottom of the moving seat so that the abutment cylinder 1 or the abutment cylinder 2 can enter the through groove upward and support the card block, so that a gap is left between the card block and the top of the placement cavity, and two sets of connecting columns are fixedly connected by a rotating cylinder, and are respectively fixedly connected to an abutment column 2 and an abutment column 3 distributed in front and behind. The movement trajectories of the connecting column one, the abutting column one and the abutting column two are controlled by the slide groove and the rotating drum. The connecting column is driven to rotate by the rotating drum, so that the abutting cylinder one or the abutting cylinder two moves to the highest point and provides support for the card block. The supporting force is provided by the self-locking property between the gear two connected to the rotating drum and the worm. When the moving seat moves outward along the surface of the slide bar, the card block is supported by rolling by the abutting cylinder one or the abutting cylinder two until the card block moves to a position disengaged from the abutting cylinder one. The cargo is just placed, and the card block and the supporting platform automatically lower their height as a whole and disengage from supporting the cargo. At this time, the lifting vehicle and the fixed platform as a whole do not need to perform unnecessary low-stroke descending operations. They only need to wait for the moving seat to reset and then directly perform lifting movements as a whole. This design greatly reduces the power output of the lifting vehicle.

[0014] 2. Then, the two groups of symmetrical connecting columns are driven to rotate by a rotating drum, so that the abutment column 1 and the abutment cylinder 1 move downward to the lowest point, and the abutment column 2 and the abutment cylinder 2 move upward to the highest point. When the moving seat is reset under the action of the driving mechanism, it will inevitably drive the card block to move back. At this time, the abutment cylinder 1 close to the card block side just moves downward, so that the card block is no longer pushed up by the abutment cylinder 1, avoiding the support table from rising again and contacting the placed goods, thereby affecting the stability of the goods placement, and the abutment cylinder 2 away from the moving seat and the card block side provides limiting support for the card block when the moving seat is almost completely reset. At this time, the support table, the card block and the moving seat have long left the area where the goods are placed, and will not have any impact on the placement of the goods.

[0015] 3. Finally, the stacker is also provided with a second motor to drive the worm to rotate, and drives the second gear and the rotating drum to rotate. On the one hand, the abutment cylinder 2 and the abutment cylinder 1 which are centrally symmetrically distributed along the axis of the rotating drum can always maintain that only one of the two is kept in the abutment support position with the block. At the same time, the self-locking property of the worm and the second gear in transmission is utilized to provide the abutment cylinder 1 and the abutment cylinder 2 with stable support for the block, which greatly improves the practicability of the device.

[0027] The stacker has been redesigned to reduce the extra descending action of the device after loading goods in the rack area, reduce the counter-torque burden of the lifting vehicle 4, and provide a slide rail 6 and a slide bar 7 so that the moving seat 8 can drive the block 9 and the support platform 10 to move along the surface of the slide rail 6 perpendicular to the track 1 to load and unload materials under the action of the driving mechanism, wherein the block 9 and the support platform 10 form a feeding platform for holding goods or unloading materials, and a guide column 16 is provided to be inserted into the inside of the block 9 so that the block 9 can only move up and down, and a through groove 14 is provided at the bottom of the moving seat 8, so that the abutment cylinder 1 27 or the abutment cylinder 29 can enter the through groove 14 upward and support the block 9, so that a gap is left between the block 9 and the top of the placement cavity 15, and two sets of connecting columns 25 are fixedly connected by the rotating cylinder 18, and are respectively fixedly connected to an abutment column 28 and an abutment column 2 distributed in front and behind. 6. The movement trajectory of the abutment column 1 26 and the abutment column 28 is controlled by the slide groove 24 and the rotating drum 18. The rotating drum 18 drives the connecting column 25 to rotate, so that the abutment cylinder 1 27 or the abutment cylinder 29 moves to the highest point and provides support for the block 9. The supporting force is provided by the self-locking property between the gear 2 19 connected to the rotating drum 18 and the worm 21. When the moving seat 8 moves outward along the surface of the slide bar 7, the abutment cylinder 1 27 or the abutment cylinder 29 supports the block 9 by rolling until the block 9 moves to a position where it is separated from the abutment cylinder 1 27. The goods are just placed, and the block 9 and the support platform 10 are automatically lowered downward as a whole and are separated from the support for the goods. At this time, the lifting vehicle 4 and the fixed platform 5 as a whole do not need to perform unnecessary low-stroke descending operations. They only need to wait for the moving seat 8 to reset and then directly perform lifting movements as a whole. This design greatly reduces the power output of the lifting vehicle 4.

[0028] Then, the two groups of symmetrical connecting columns 25 are driven to rotate by the rotating drum 18, so that the abutment column 1 26 and the abutment cylinder 1 27 move downward to the lowest point, and the abutment column 28 and the abutment cylinder 29 move upward to the highest point. When the moving seat 8 is reset under the action of the driving mechanism, it will inevitably drive the block 9 to move back. At this time, the abutment cylinder 1 27 close to the side of the block 9 just moves downward, so that the block 9 is no longer pushed upward by the abutment cylinder 1 27, avoiding the support platform 10 from rising again and contacting the placed goods, thereby affecting the stability of the goods placement, and the abutment cylinder 2 29 away from the moving seat 8 and the block 9 side provides limiting support for the block 9 when the moving seat 8 is almost completely reset. At this time, the support platform 10, the block 9 and the moving seat 8 have long left the area where the goods are placed, and will not have any impact on the placement of the goods.

[0029] Finally, the stacker is also provided with a motor 22 to drive the worm 21 to rotate, and drive the gear 2 19 and the rotating drum 18 to rotate. On the one hand, the abutment cylinder 2 29 and the abutment cylinder 1 27, which are centrally symmetrically distributed along the axis of the rotating drum 18, can always maintain a position in which only one of the two is in abutment and support with the block 9. At the same time, the self-locking property of the worm 21 and the gear 2 19 in transmission is utilized to provide the abutment cylinder 1 27 and the abutment cylinder 2 29 with stable support for the block 9, thereby greatly improving the practicability of the device.

[0030] The slide rails 6 are provided in two groups, and are distributed on the top of the fixed platform 5 in a left and a right manner. The slide bar 7 is slidably mounted on the upper surface of the slide rails 6. The top of the slide bar 7 is fixedly connected to the bottom of the moving seat 8. The driving mechanism is used to drive the slide bar 7 and the moving seat 8 to move.

[0031] The slide rail 6 enables the moving seat 8, the block 9 and the support platform 10 to drive the goods to move back and forth along the extension direction of the slide rail 6 through the slide bar 7, and the slide bar 7 is driven by the driving mechanism so that the moving seat 8 can move freely.

[0032] The driving mechanism includes two groups of motors 12 distributed front and back, the output shaft of the motor 12 is fixedly mounted with a gear 13, the right side of the right slide bar 7 is fixedly connected with a rack 11, and the gear 13 is meshed with the rack 11;

[0033] The power of the driving mechanism comes from the motor 12 and gear 13 distributed front and back. The rack 11 is fixedly installed on the side of the slide bar 7 on the right. When the two sets of motors 12 and gears 13 rotate, they will act on the rack 11 at the same time, converting the rotation from the motor 12 into linear motion. The distribution of the two sets of motors 12 and gears 13 can enable the slide bar 7 to exert its maximum motion range.

[0034] The through groove 14 is located in the middle of the bottom surface of the moving seat 8 and penetrates upward to the inner wall of the placement cavity 15. The abutment tube 1 27 and the abutment tube 2 29 can enter the through groove 14.

[0035] The opening of the through slot 14 enables the abutment tube 1 27 and the abutment tube 2 29 to enter the placement cavity 15 from here and provide rolling support for the clamping block 9 .

[0036] The drum 18 and the worm 21 are arranged one above the other and perpendicular to each other, and the output shaft of the motor 22 is fixedly connected to the worm 21;

[0037] The vertical distribution of the rotating drum 18 and the worm 21 enables the worm 21 to drive the gear 2 19 and the rotating drum 18 to rotate in one direction, while the rotating drum 18 and the gear 2 19 cannot drive the worm 21 to rotate, thereby effectively protecting the motor 2 22 and providing stability and supporting effect to the abutment drum 1 27 or the abutment drum 2 29.

[0038] The outer surface of the abutment tube 29 abuts against the top of the fixing platform 5, and the inner wall of the slide groove 24 is designed in an arc shape;

[0039] The second abutment tube 29 is located at the lowest position, while the first abutment tube 27 is located at the highest position, thereby achieving a supporting effect on the clamping block 9 and an automatic descending delayed abutment supporting function of the clamping block 9 after unloading.

[0040] The upper surface of the support platform 10 is larger than the upper surface of the block 9, and a gap is provided between the bottom of the block 9 and the bottom of the placement cavity 15;

[0041] The large area design of the support platform 10 enables it to carry larger goods, thereby improving the practicality of the device.

[0042] The highest points of the outer surfaces of the abutment tube 1 27 and the abutment tube 2 29 are lower than the top of the inner wall of the through groove 14, and each group of connecting columns 25 is provided with two left and right ones, and are fixedly connected to the two ends of the outer surface of the rotating drum 18;

[0043] The abutting tube 1 27 and the abutting tube 2 29 only abut against the bottom of the clamping block 9 and do not contact any part of the moving seat 8 to avoid jamming.

[0044] Working principle:

[0045] First, the device is set between two groups of three-dimensional storage racks, so that the track 1 is placed between the two groups of three-dimensional storage racks, so that the transport vehicle 2 can move back and forth along the surface of the track 1. When loading, the lifting vehicle 4 moves downward to the material-taking height, and controls the motor 12 to drive the gear 13 to rotate, and through the meshing transmission with the rack 11, drives the slide bar 7, the moving seat 8, the block 9 and the support platform 10 to extend in the vertical direction of the track 1 as a whole. When the goods are completely located above the support platform 10, start the lifting vehicle 4 and drive the goods to move upward as a whole. Then, control the motor 12 and the gear 13 to rotate, and drive the moving seat 8 to reset;

[0046] Then, the transport vehicle 2 moves along the surface of the track 1, and the lifting vehicle 4 drives the fixed platform 5 to move upward to the cargo stacking area designated by the rack. When the cargo stacking area is located on the side close to the abutment cylinder 27, the abutment cylinder 27 moves upward and provides support for the block 9, the motor 12 is started, and the gear 13 is driven to rotate, so that the rack 11 drives the slide bar 7, the moving seat 8, the block 9, the support platform 10 and the cargo above the support platform 10 to move horizontally to the side of the abutment cylinder 27. At this time, the block 9 The bottom of the block 9 rolls and abuts against the outer surface of the abutment tube 1 27, and drives the abutment tube 1 27 to rotate. When the moving seat 8 is extended outward as a whole to the longest stroke, the goods reach the placement area. At this time, the bottom of the block 9 is separated from the abutment with the abutment tube 1 27 and moves downward under the action of gravity. At this time, the goods that have lost the support of the support platform 10 are just placed on the storage rack. At the same time, since the support platform 10 moving downward is separated from the support of the bottom of the goods, the lifting vehicle 4 as a whole does not need to make an additional descending action at this time;

[0047] Finally, in order to prevent the block 9 from abutting against the abutment cylinder 1 27 and lifting again during the resetting process of the moving seat 8, which would affect the stability of the goods after they are placed, the motor 22 is started to drive the worm 21, the gear 2 19 and the rotating cylinder 18 to rotate. Figure 5 As shown, the rotating drum 18 drives the connecting column 25, the abutting column 1 26, the abutting cylinder 1 27, the abutting column 28 and the abutting cylinder 2 29 to rotate clockwise around the axis of the rotating drum 18, so that the abutting cylinder 1 27 moves to the lowest point and the abutting cylinder 2 29 moves to the highest point. Then, the motor 22 is stopped, and the self-locking property of the worm 21 and the gear 2 19 provides supporting force for the abutting cylinder 2 29. At this time, the moving seat 8 and the block 9 that move back and forth will not abut against the abutting cylinder 1 27 until the moving seat 8 is completely reset, that is, the support platform 10 is out of the area of ​​the storage rack. At this time, the abutting cylinder 29 just provides support for the block 9.
