This improves safety.

Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, specifically to a transportation device and a stacking method for packaging traditional Chinese medicine decoction pieces. Background Technology

[0002] Stacker cranes (also known as stacker hoists) are core equipment in automated storage and retrieval systems (AS / RS). They are mainly used for the rapid and precise storage and retrieval of goods in the aisles of high-rise racks. Their main structure includes a frame that can move along a track, a lifting platform installed inside the frame, and forks installed on the platform for picking up and placing goods. In the warehousing and management of traditional Chinese medicine decoction pieces, the decoction pieces are generally first packaged in plastic bags, then multiple plastic bags are sealed in cardboard boxes, the cardboard boxes are stacked and placed on pallets, and finally the stacker crane is used to transport the pallets and cardboard boxes to the racks.

[0003] In actual use, stacker cranes in aisle transport pose certain safety hazards: stacker cranes typically use laser rangefinders and encoders to position goods. However, vibrations during operation and dust from medicinal herbs adhering to the optical sensors can easily cause inaccuracies. When pallets are placed on the racks, if the pallet edges contact the bottom and side edges of the racks and the forks forcefully push the goods in, the goods may be placed crookedly or become stuck on the forks, which can easily lead to accidents. In addition, if some medicinal herbs are lightweight, the pallets may easily sway during transport due to gravity alone, and there is a lack of appropriate measures to ensure stability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a stacking method for a transport device and packaging of traditional Chinese medicine decoction pieces, which has advantages such as high safety and solves the problems of insufficient positioning accuracy due to damage to positioning equipment and easy shaking of lighter goods in existing aisle stacker cranes, resulting in insufficient safety.

A driving bevel gear is fixed on the second rotating shaft, and a driven bevel gear is fixed on the first rotating shaft. The driving bevel gear meshes with the driven bevel gear. The operation of the drive motor drives the vertical rod and the horizontal rod to rotate around the first rotating shaft and the second rotating shaft respectively, forcing the vertical rod and the horizontal rod to swing and then adhere to the surface of the strip plate.

[0012] Preferably, the drive assembly includes a drive motor fixed to the side of the bracket, a worm gear fixed on the output shaft of the drive motor, two third bearing seats mounted on the worm gear, the two third bearing seats being fixed to the side of the bracket, and a worm wheel fixed on the base shaft, the worm wheel meshing with the worm gear.

[0017] Compared with the prior art, the present invention provides a transport device and a stacking method for packaging traditional Chinese medicine decoction pieces, which has the following beneficial effects:

[0018] 1. This type of transport device and stacking method for packaging Chinese herbal medicine pieces, by setting up a drive component and a limiting bar installed on the pallet, allows the limiting bar to rotate and fit against the side of the pallet when the goods are lifted, thus positioning the pallet and improving its stability during movement. Before the pallet is placed into the storage area on the shelf, the limiting bar is driven to rotate again by the drive component, causing the vertical and horizontal bars on the limiting bar to move onto the pallet's movement path. The positional deviation is monitored by whether the horizontal and vertical bars come into contact with obstacles during their movement, which helps to avoid positional deviations caused by damage to the positioning parts, ultimately leading to safety accidents and improving safety.

[0019] 2. This type of transport device and stacking method for packaging Chinese herbal medicine pieces, by starting the drive motor, forces the horizontal and vertical bars to rotate to fit against the outer wall of the strip plate, which is conducive to the storage of the horizontal and vertical bars, reduces the volume of the limiting baffle, and avoids contact with other objects during loading and transferring of goods, thus preventing obstruction and affecting the transport. By setting the drive component, the entire limiting baffle can also be rotated to store the entire limiting baffle on one side of the bracket, avoiding interference with the operation.

[0020] 3. This type of transport device and stacking method for Chinese herbal medicine packaging, by setting up a secondary detection component, can also detect the placement position of the pallet during loading, preventing the pallet edges from being exposed outside the shelf, further reducing safety risks, improving safety, and facilitating the staff to quickly inspect and maintain the ranging system.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a transportation device and a stacking method for packaging Chinese herbal medicine slices.

[0035] Example 1: Please refer to Figures 1-5 A transport device includes a frame 1, a loading platform 2 mounted on the frame 1, and forks 3 mounted on the loading platform 2. The forks 3 include two brackets 4 that can extend and retract in both directions. Each of the two brackets 4 is provided with two sets of limiting baffles 5 and a drive assembly 6 on its outer side. The limiting baffles 5 are used to limit the edge of the pallet. The limiting baffles 5 include a base block 51 that is movably connected to the outer wall of the brackets 4 and a main detection assembly 52 mounted 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 retractable vertical rod 53 and a horizontal rod 54. The bottom end of the vertical rod 53 corresponds to the bottom of the pallet, and the end of the horizontal rod 54 corresponds to the side of the pallet. The drive assembly 6 is used to drive the limiting baffles 5 to swing.

[0036] After the pallet is loaded onto the forks 3, the drive assembly 6 operates to force the limit baffle 5 to swing to a vertical position and fit against the edge of the pallet, thereby limiting the position of the pallet;

[0037] During unloading, the drive assembly 6 operates, forcing the limit baffle 5 to swing to a horizontal position, the bracket 4 extends towards the shelf, and the main detection assembly 52 operates to monitor the accuracy of the forks 3. If the accuracy is incorrect, the forks 3 are controlled to stop the loading operation.

[0038] The pallet is existing technology. The goods transported by this device are pallets and cardboard boxes containing Chinese herbal medicine slices stacked on the pallets. When the fork 3 is in operation, the bracket 4 can extend horizontally to the side of the loading platform 2, thereby inserting the bracket 4 into the pallet. Then the loading platform 2 moves vertically along the frame 1 to lift the pallet to the specified height. In the initial state, the limiting baffle 5 is horizontal and stored on the side of the bracket 4.

[0039] In use, when the tray 4 lifts the pallet, the drive assembly 6 is activated. After the drive assembly 6 operates, it drives the limit baffle 5 to rotate 270 degrees, causing the limit baffle 5, which was originally horizontal on the side of the tray 4, to rotate into a vertical position. One end of the limit baffle 5 extends vertically upward above the tray 4, just abutting against the edge of the pallet. During the vertical movement of the pallet, it plays a positioning role for the pallet, improving the stability of the pallet. When the pallet moves to the storage area directly facing the shelf, the drive assembly 6 on the side closest to the shelf is activated. The drive assembly 6 forces the matching limit baffle 5 to... Rotate 90 degrees. At this time, the limit baffle 5 is in a horizontal state, and one end of the limit bar extends towards the storage area on the shelf. At this time, the bottom end of the vertical bar 53 on the limit bar is at the same height as the bottom of the pallet, and one end of the horizontal bar 54 on the limit bar is at the same position as the side edge of the pallet. Then, the forks 3 operate, forcing the bracket 4 to move towards the shelf. If the position is accurate, there will be no obstruction on the movement path of the horizontal bar 54 and the vertical bar 53. If there is an error in the position, the horizontal bar 54 or the vertical bar 53 will touch the metal beam on the shelf on the movement path, and then the forks 3 will be controlled to stop operating to avoid safety accidents.

[0040] By setting up the drive assembly 6 and the limit bar installed on the bracket 4, when lifting goods, the drive assembly 6 can force the limit bar to rotate and fit against the side of the pallet, thus positioning the pallet and improving the stability of the pallet during movement. Before the pallet is sent into the storage area on the shelf, the drive assembly 6 drives the limit bar to rotate again, causing the vertical bar 53 and horizontal bar 54 on the limit bar to move onto the pallet's movement path. The positional deviation is monitored by whether the horizontal bar 54 and vertical bar 53 come into contact with obstacles during their movement. This helps to avoid positional deviation caused by damage to the positioning parts, which could ultimately lead to safety accidents, thus improving safety.

[0041] Example 2: See Figures 4-6 Unlike the above embodiments, the base block 51 is located on one side of the end of the bracket 4, and a base shaft 55 is fixed on the base block 51. The base shaft 55 is rotatably connected to the side wall of the bracket 4. A guide groove 56 is formed on the surface of the base block 51. 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. A main pressure sensor 522 is fixed on the inner wall of the guide groove 56. A spring 523 is fixedly connected between the main pressure sensor 522 and the strip plate 521. The ends of the vertical rod 53 and the horizontal rod 54 are both installed on the end of the strip plate 521 away from the base block 51.

[0042] The width of the base block 51 is the same as the width of the strip plate 521. When in use, the drive assembly 6 operates, forcing the entire limit baffle 5 to rotate to a horizontal state. At this time, one end of the strip plate 521 extends towards the shelf. When loading goods into the storage area, the bracket 4 moves horizontally, simultaneously driving the base block 51, the strip plate 521, and the pallet to move. When there is a positioning accuracy error, the vertical bar 53 and the horizontal bar 54 at the end of the strip plate 521 will contact the shelf during the movement, thereby hindering 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.

[0043] By setting the limit baffle 5 as a base block 51 and a strip plate 521, the strip plate 521 is movably mounted on the base block 51 by a spring 523 and a pressure sensor. If the limit baffle 5 is obstructed by the shelf when it moves with the bracket 4 to the storage area, it indicates that there is an accuracy error and safety risk. This will control the fork 3 to stop operating, avoid the occurrence of safety accidents in time, and facilitate maintenance personnel to quickly check and adjust.

[0044] Example 3, see Figures 5-10Unlike the above embodiments, the strip plate 521 has a groove 524 at the end away from the base block 51. A first rotating shaft 57 is fixed to one end of the vertical rod 53. The first rotating shaft 57 is movably mounted in the groove 524 via a first bearing seat. A second rotating shaft 58 is also provided inside the groove 524. The second rotating shaft 58 is perpendicular to the first rotating shaft 57 and is movably mounted in the groove 524 via a second bearing seat. A connecting block 59 is fixed to the second rotating shaft 58. The end of the horizontal rod 54... The drive motor 7 is fixedly connected to the connecting block 59 and is fixedly connected inside the groove 524. The output shaft of the drive motor 7 is fixed to the end of the second rotating shaft 58. The second rotating shaft 58 is fixed with a driving bevel gear 8 and the first rotating shaft 57 is fixed with a driven bevel gear 9. The driving bevel gear 8 and the driven bevel gear 9 mesh. The drive 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 then stick to the surface of the strip plate 521.

[0045] When the accuracy measurement function is not required, the drive motor 7 is started. When the drive 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 horizontal 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 bar 53 to swing. Finally, the vertical bar 53 and the horizontal bar 54 rotate 90 degrees at the same time, so that the vertical bar 53 and the horizontal bar 54 fit against the outer wall of the strip plate 521, thereby greatly reducing the volume of the strip limit baffle 5 and playing a storage role.

[0046] By starting the drive 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 facilitates the storage of the horizontal bar 54 and the vertical bar 53, reduces the volume of the limit baffle 5, and avoids contact with other objects during loading and transferring of goods, thus preventing obstruction and affecting the conveying.

[0047] Example 4, see Figure 6 Unlike the above embodiments, the drive assembly 6 includes a drive motor 61 fixed to the side of the bracket 4, a worm gear 62 fixed on the output shaft of the drive motor 61, two third bearing seats 63 mounted on the worm gear 62, the two third bearing seats 63 fixed to the side of the bracket 4, and a worm wheel 64 fixed on the base shaft 55, which meshes with the worm gear 62.

[0048] The worm gear 62 and worm wheel 64, in their meshed state, have a self-locking effect, similar to existing technologies. During operation, the drive motor 61 is started, causing the worm gear 62 to rotate. This rotation of the worm gear 62, in turn, drives the worm wheel 64, which in turn drives the base shaft 55. The base shaft 55 then drives the base block 51, which in turn causes the entire limiting baffle 5 to swing. This allows for adjustment of the limiting baffle 5's angle according to different work requirements. During goods transfer, the limiting baffle 5 is driven to rotate to a vertical position to position and protect the pallet edge, preventing unauthorized pallet movement. When unloading, the limiting baffle 5 is driven to rotate to a horizontal position and extend towards the shelf for risk detection. During other operations, the limiting baffle 5 is driven to rotate to a horizontal position and extend towards the center of the bracket 4, storing the entire limiting baffle 5 on one side of the bracket 4 to avoid interference with operations.

[0049] Example 5, see Figure 9 and Figure 11 Unlike the above embodiments, a secondary detection component 10 is installed on the side of the base block 51. The secondary detection component 10 includes a secondary pressure sensor 101 movably mounted on the base block 51. The secondary detection component 10 is used to monitor the depth of the fork 3 inserted into the shelf during loading. The secondary detection component 10 includes a rack 102 slidably connected to the side wall of the base block 51. 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. The output shaft of the adjusting motor 103 passes through the outside of the guide groove 56 and is fixed with a drive gear 104. The drive gear 104 meshes with the rack 102. A main slide groove is provided on the inner side wall of the guide groove 56. A main slider matching the main slide groove is provided on the end edge of the strip plate 521. A secondary slider is fixed on the outer wall of the base block 51. 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.

[0050] When the ranging system malfunctions, it can easily cause uneven pushing depths during loading. In this case, when the pallet is placed in the storage area on the shelf, the pallet edge cannot be effectively supported and extends beyond the storage area, making it prone to falling or interfering with the movement of other goods, further causing safety accidents. During use, when loading, one of the limiting baffles 5 on the bracket 4 is horizontal, facing the storage area, while the other limiting baffle 5, away from the storage area, remains vertical. At this time, the rack 102 is close to the pallet edge and vertically downwards. When the bracket 4 pushes the pallet into the deepest part of the storage area... When the adjustment motor 103 is started, the adjustment motor 103 drives the drive gear 104 to rotate. When the drive 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 inserted into the shelf, the rack 102 will contact the shelf when it moves downward, ensuring that the bottom of the entire pallet is supported. If the auxiliary pressure sensor 101 at the bottom does not have any obstruction when the rack 102 moves downward, that is, there is no support structure at the bottom edge of the pallet, the pallet has a safety risk of placement deviation when loading materials.

[0051] By setting up the secondary detection component 10, the placement position of the pallet can also be detected during loading, preventing the pallet edges from being exposed outside the shelf, further reducing safety risks, improving safety, and facilitating staff to quickly inspect the ranging system.
