Description

Technical Field

[0001] The present invention relates to the technical field of transport devices, in particular to a transport device and a stacking method for packaging Chinese herbal medicine slices. Background Art

[0002] Aisle stacker cranes (also known as stacker cranes) are the core equipment in automated warehouses.

Their main structure includes a frame that can move along the track, a cargo platform installed on the inside of the frame that can be raised and lowered, and a fork installed on the cargo platform for picking up and placing goods. In the warehousing management of Chinese herbal medicines, the herbal medicines are generally packaged in plastic bags first, and then multiple plastic bags are encapsulated in cartons. The cartons are stacked and placed on pallets. Finally, a stacker crane is used to transport the pallets and cartons to the shelves.

[0003] In actual use, there are certain safety hazards when transporting goods by aisle stackers: aisle stackers generally use laser ranging and encoders to achieve positioning when placing goods. However, when the stacker vibrates during use, and when the dust of Chinese herbal medicines adheres to the optical sensor, it is easy to cause inaccuracy. At this time, when the pallet is placed in the bracket, the edge of the pallet contacts the bottom edge and side edge of the shelf. If the fork is forcibly pushed in, the goods will be placed crookedly or stuck on the fork, which can easily cause safety accidents. In addition, if some Chinese herbal medicines are light in weight, the pallet can easily shake during the transfer process relying solely on gravity, and there is a lack of appropriate measures to ensure stability.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As introduced in the background technology, in order to solve the deficiencies in the existing technology and the above technical problems, the present application proposes a transport device and a stacking method for packaging Chinese herbal medicine pieces.

[0022] Example 1: Please refer to Figure 1-Figure 5, a transport device includes a frame 1, a cargo platform 2 installed on the frame 1 and a fork 3 installed on the cargo platform 2, the fork 3 includes two brackets 4 that can be extended and retracted in two directions, two sets of limit baffles 5 and a drive assembly 6 are provided on the outside of the two brackets 4, the limit baffles 5 are used to limit the edge of the pallet, the limit baffle 5 includes a base block 51 movably connected to the outer wall of the bracket 4 and a main detection assembly 52 installed on the base block 51, the main detection assembly 52 is used to detect the accuracy of loading, the main detection assembly 52 includes a vertical rod 53 and a cross rod 54 that can be retracted, the bottom end of the vertical rod 53 corresponds to the bottom position of the pallet, and the end of the cross rod 54 corresponds to the side position of the pallet, and the drive assembly 6 is used to drive the limit baffle 5 to swing; After the pallet is loaded on the fork 3, the driving assembly 6 operates to force the limit baffle 5 to swing to a vertical position and fit the edge of the pallet, thereby limiting the position of the pallet; During unloading, the driving assembly 6 operates to force the limit baffle 5 to swing to a horizontal state, the bracket 4 extends toward the shelf, and the main detection assembly 52 operates to monitor the accuracy of the fork 3. If the accuracy is wrong, the fork 3 is controlled to stop the loading operation.

[0023] Among them, the pallet is a prior art. The cargo transported by this device is a pallet and cartons containing Chinese herbal medicine pieces stacked on the pallet. The bracket 4 on the fork 3 can extend horizontally to the side of the loading platform 2 during operation, so that the bracket 4 is inserted into the pallet. Then the loading platform 2 moves vertically along the frame 1 to lift the pallet to a specified height. In the initial state, the limit baffle 5 is horizontal and stored on the side of the bracket 4. When in use, when the bracket 4 lifts the pallet, the driving assembly 6 is started. After the driving assembly 6 is running, the limit baffle 5 is driven to rotate 270 degrees, so that the limit baffle 5 originally located on the side of the bracket 4 in a horizontal state is rotated into a vertical state. One end of the limit baffle 5 extends vertically above the upper bracket 4 and just abuts against the edge of the pallet. It plays a role in positioning the pallet during the vertical movement of the pallet, thereby improving the stability of the pallet. When the pallet moves to the storage area facing the shelf, the driving assembly 6 close to the side of the shelf is started, and the driving assembly 6 forces the matching limit baffle 5 to move in the opposite direction. After rotating 90 degrees, the limit baffle 5 is in a horizontal state, and one end of the limit baffle extends toward the storage area on the shelf. At this time, the bottom end of the vertical rod 53 on the limit baffle is at the same height as the bottom of the pallet, and one end of the cross bar 54 on the limit baffle is at the same position as the side edge of the pallet. Then the fork 3 is operated to force the bracket 4 to move toward the shelf. If the position is accurate, there will be no obstacles in the moving path of the cross bar 54 and the vertical rod 53. If there is an error in the position, the cross bar 54 or the vertical rod 53 will touch the metal beam on the shelf on the moving path, and then the fork 3 is controlled to stop moving to avoid safety accidents.

[0024] By providing a drive assembly 6 and a limit stop bar installed on the bracket 4, the drive assembly 6 can be used to force the limit stop bar to rotate and fit into the side of the pallet when lifting the goods, thereby positioning the pallet and improving the stability of the pallet during movement. Before the pallet is sent to the storage area on the shelf, the drive assembly 6 is used to drive the limit bar to rotate again, so that the vertical rod 53 and the horizontal rod 54 on the limit stop bar are moved to the moving path of the pallet. Whether there is a position deviation is monitored by whether the horizontal rod 54 and the vertical rod 53 contact obstacles during the movement process, which is conducive to avoiding the position deviation caused by damage to the positioning parts, which ultimately causes a safety accident, thereby improving safety.

[0025] Example 2: See Figure 4-Figure 6 , different from the above embodiment, the base block 51 is arranged on one side of the end of the bracket 4, and a base shaft 55 is fixed on the base block 51, and the base shaft 55 is rotatably connected to the side wall of the bracket 4, and a guide groove 56 is provided on the surface of the base block 51, and the main detection component 52 includes a strip plate 521, one end of the strip plate 521 extends into the guide groove 56 and is slidably connected to the guide groove 56, and a main pressure sensor 522 is fixed to the inner wall of the guide groove 56, and a spring 523 is fixedly connected between the main pressure sensor 522 and the strip plate 521, and the end of the vertical rod 53 and the end of the horizontal rod 54 are both installed on the end of the strip plate 521 away from the base block 51.

[0026] The width of the base block 51 is the same as that of the strip plate 521. When in use, the driving assembly 6 operates to force the entire limit baffle 5 to rotate to a horizontal state. At this time, one end of the strip plate 521 extends toward the shelf. When loading goods into the storage area, the bracket 4 moves horizontally, driving the base block 51, the strip plate 521 and the pallet to move at the same time. When there is a positioning accuracy error, the vertical rod 53 and the horizontal rod 54 at the end of the strip plate 521 will contact the shelf during the movement, thereby blocking the strip plate 521 and compressing the spring 523. After the spring 523 is compressed, the elastic force increases and acts on the main pressure sensor 522. The main pressure sensor 522 detects the increase in pressure value and sends an electrical signal, which controls the fork 3 to stop operating through the PLC system. By setting the limit baffle 5 as a base block 51 and a strip plate 521, the strip plate 521 is movably installed on the base block 51 through a spring 523 and a pressure sensor. If the limit baffle 5 is blocked by the shelf when moving with the bracket 4 to the storage area, it means that there is an accuracy error and a safety risk, and then the fork 3 is controlled to stop running, thereby avoiding the occurrence of safety accidents in time and facilitating maintenance personnel to quickly check and adjust.

[0027] Example 3, see Figures 5-10, which is different from the above embodiment, the strip plate 521 is provided with a groove 524 at one end away from the base block 51, and a first rotating shaft 57 is fixed to one end of the vertical rod 53. The first rotating shaft 57 is movably installed in the groove 524 through a first bearing seat. A second rotating shaft 58 is further provided inside the groove 524. The second rotating shaft 58 is perpendicular to the first rotating shaft 57 and is movably installed in the groove 524 through a second bearing seat. A connecting block 59 is fixed to the second rotating shaft 58. The end of the cross bar 54 It is fixedly connected to the connecting block 59, and a transmission motor 7 is fixedly connected to the inside of the groove 524. The output shaft of the transmission motor 7 is fixed to the end of the second rotating shaft 58. A driving bevel gear 8 is fixed on the second rotating shaft 58, and a driven bevel gear 9 is fixed on the first rotating shaft 57. The driving bevel gear 8 is engaged with the driven bevel gear 9. The transmission motor 7 drives the vertical rod 53 and the horizontal rod 54 to rotate around the first rotating shaft 57 and the second rotating shaft 58 respectively, forcing the vertical rod 53 and the horizontal rod 54 to swing and fit the surface of the strip plate 521.

[0028] Among them, when the precision measurement function is not needed, the transmission motor 7 is started. When the transmission motor 7 is running, it drives the second rotating shaft 58 to rotate. When the second rotating shaft 58 rotates, it drives the connecting block 59 to rotate. When the connecting block 59 rotates, it drives the cross bar 54 to swing. At the same time, the second rotating shaft 58 also drives the active bevel gear 8 to rotate. When the active bevel gear 8 rotates, it drives the driven bevel gear 9 to rotate. When the driven bevel gear 9 rotates, it drives the first rotating shaft 57 to rotate. When the first rotating shaft 57 rotates, it drives the vertical rod 53 to swing. Finally, the vertical rod 53 and the cross bar 54 rotate 90 degrees at the same time, so that the vertical rod 53 and the cross bar 54 fit the outer wall of the strip plate 521, thereby greatly reducing the volume of the strip limit baffle 5, playing a role in storage. By starting the transmission motor 7, the horizontal bar 54 and the vertical bar 53 are forced to rotate to fit the outer wall of the strip plate 521, which is conducive to storing the horizontal bar 54 and the vertical bar 53, reducing the volume of the limit baffle 5, and avoiding contact with other objects when loading and transferring goods, thereby affecting transportation.

[0029] Example 4, see Figure 6 , different from the above embodiment, the driving assembly 6 includes a driving motor 61 fixed to the side of the bracket 4, a worm 62 is fixed on the output shaft of the driving motor 61, two third bearing seats 63 are installed on the worm 62, the two third bearing seats 63 are fixed to the side of the bracket 4, a worm gear 64 is fixed on the base shaft 55, and the worm gear 64 is engaged with the worm 62.

[0030] Among them, the worm 62 and the worm wheel 64 have a self-locking effect in the meshing state compared with the existing technology. When in use, the drive motor 61 is started, and the drive motor 61 drives the worm 62 to rotate after it runs. When the worm 62 rotates, it drives the worm wheel 64 to rotate. When the worm wheel 64 rotates, it drives the base shaft 55 to rotate. When the base shaft 55 rotates, it drives the base block 51 to rotate, and then drives the entire limit baffle 5 to swing, which is conducive to adjusting the angle of the limit baffle 5 according to different work requirements. When transferring goods, the limit baffle 5 is driven to rotate to a vertical state to position and protect the edge of the pallet to prevent the pallet from moving at will. When unloading goods, the limit baffle 5 is driven to rotate to a horizontal state and extend toward the shelf direction to perform risk detection work. During the rest of the work, the limit baffle 5 is driven to rotate to a horizontal state and extend toward the center of the bracket 4 to store the entire limit baffle 5 on one side of the bracket 4 to avoid interference with work.

[0031] Example 5, see Figure 9 and Figure 11 , different from the above embodiment, a secondary detection component 10 is installed on the side of the base block 51, and the secondary detection component 10 includes a secondary pressure sensor 101 movably installed on the base block 51. The secondary detection component 10 is used to monitor the depth of the fork 3 inserted into the shelf when loading goods, and the secondary detection component 10 includes a rack 102 slidably connected to the side wall of the base block 51, and the secondary pressure sensor 101 is fixed to the end of the rack 102. An adjusting motor 103 is fixed inside the guide groove 56, and the output shaft of the adjusting motor 103 passes through the outside of the guide groove 56 and is fixed with a driving gear 104, and the driving gear 104 is engaged with the rack 102. The inner wall of the guide groove 56 is provided with a main slide groove, and the end edge of the strip plate 521 is provided with a main slide groove matching the main slide groove. A secondary slide groove is fixed to the outer wall of the base block 51, and a secondary slide groove matching the guide rail is opened on the rack 102. The sliding direction of the rack 102 is consistent with the sliding direction of the strip plate 521.

[0032] Among them, when the distance measurement system is inaccurate, it is easy to cause the problem of different pushing depths when loading goods. At this time, when the pallet is placed in the storage area on the shelf, the edge of the pallet cannot be effectively supported and extends outside the storage area, which is easy to fall or interfere with the movement of other goods, further causing safety accidents. During use, when loading goods, one of the limit baffles 5 on the bracket 4 is in a horizontal state facing the storage area, and the other limit baffle 5 away from the storage area remains in a vertical state. At this time, the rack 102 is close to the edge of the pallet and vertically downward. When the bracket 4 pushes the pallet into the deepest part of the storage area When the adjusting motor 103 is started, the adjusting motor 103 drives the driving gear 104 to rotate when the adjusting motor 103 is running. When the driving gear 104 rotates, it drives the rack 102 to move vertically downward. The rack 102 drives the auxiliary pressure sensor 101 at the bottom to move vertically downward. At this time, since the rack 102 is located at the outer edge of the pallet, if the pallet is fully extended into the shelf at this time, the rack 102 will move downward and contact the shelf to ensure that the bottom of the entire pallet is supported. If the auxiliary pressure sensor 101 at the bottom is not blocked when the rack 102 moves downward, that is, there is no supporting structure at the bottom edge of the pallet, there is a safety risk of the pallet being placed in a position deviated during loading. By setting up the auxiliary detection component 10, the placement position of the pallet can also be detected when loading goods, avoiding the edge of the pallet being exposed outside the shelf, further reducing safety risks, improving safety, and facilitating rapid maintenance of the distance measurement system by staff.
