DETAILED DESCRIPTION

[0068] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0069] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0070] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] like Figures 1 to 11 As shown, the present invention discloses a double-column stacker for carrying a medicine decocting pot.

[0072] The double-column stacker includes a straight-line extending ground rail assembly 1 and a stacker body 2. The ground rail assembly 1 is laid flat. The stacker body 2 is located above the ground rail assembly 1, and the stacker body 2 can move on the ground rail assembly 1 along the extension direction of the ground rail assembly 1. A traction mechanism 3 is provided between the ground rail assembly 1 and the stacker body 2, and the traction mechanism 3 is connected to the ground rail assembly 1 and the stacker body 2, and the traction mechanism 3 is used to drive the stacker body 2 to move on the ground rail assembly 1 along the extension direction of the ground rail assembly 1.

[0073] Specifically, in this embodiment, the ground rail assembly 1 includes two parallel linear rails 11, and a plurality of anchor plates 12 are arranged below each linear rail 11, and the anchor plates 12 are used to fix the linear rail 11 on the installation ground. The plurality of anchor plates 12 are arranged at intervals along the extension direction of the linear rail 11. The anchor plates 12 are fixedly connected to the linear rail 11. The ends of the two linear rails 11 are connected by a connecting plate 13, and the connecting plates 13 are fixedly connected to the two linear rails 11 respectively.

[0074] In this embodiment, at both ends of the linear track 11, a vertically arranged reflective mirror panel 14 is installed on the linear track 11, and the reflective mirror surface of the reflective mirror panel 14 is located above the linear track 11 and the reflective mirror surface of the reflective mirror panel 14 faces the stacker body 2. A reflective photoelectric sensor 4 is fixed on the side of the stacker body 2 facing the direction of the reflective mirror panel 14. The reflective photoelectric sensor 4 and the reflective mirror panel 14 are arranged relative to each other. The reflective photoelectric sensor 4 sends an infrared signal to the reflective mirror panel 14, and the infrared signal returns the infrared signal to the reflective photoelectric sensor 4 via the reflective mirror surface of the reflective mirror panel 14. When foreign matter appears on the upper surface of the linear track 11, the foreign matter blocks the infrared emitted by the reflective photoelectric sensor 4. When the reflective photoelectric sensor does not receive the infrared signal reflected back by the reflective mirror panel 14, it means that there is a foreign matter on the linear track 11, and the stacker body 2 stops moving at this time.

[0075] In this embodiment, an origin scale 15 extending horizontally toward the stacker is provided on the connecting plate 13 at one end of the linear track 11. An origin sensor 5 is fixed at a position where the stacker body 2 is opposite to the origin scale 15. When the stacker body 2 approaches the origin scale 15, the origin sensor 5 can move above the origin scale 15. The cooperation between the origin sensor 5 and the origin scale 15 facilitates the equipment to find the zero point and check the error during the debugging of the double-column stacker.

[0076] In this embodiment, limit sensors 16 are also installed at both ends of the linear track 11. When the distance between the stacker body 2 and the limit sensor 16 reaches a set distance value, the stacker body 2 stops moving. The limit sensor 16 prevents the stacker body 2 from accidentally running off the track.

[0077] In this embodiment, a plurality of movable seats 6 are disposed at positions where the stacker body 2 is opposite to each linear track 11, and the plurality of movable seats 6 are arranged along the extension direction of the linear track 11. The movable seats 6 are fixedly connected to the stacker body 2, and the movable seats 6 are slidably connected to the linear track 11. When the stacker body 2 is moved by the traction mechanism 3, the movable seats 6 move along the extension direction of the linear track 11.

[0078] Specifically, in this embodiment, the stacker body 2 includes a frame 21 , a telescopic fork 22 movably connected to the frame 21 , and a synchronous belt traction assembly 23 for pulling the telescopic fork 22 to move in the vertical direction. The synchronous belt traction assembly 23 is installed on the frame 21 .

[0079] Specifically, in this embodiment, the synchronous belt traction assembly 23 includes a drive shaft 231 rotatably connected to the top of the frame 21, and the drive shaft 231 is arranged horizontally. A servo motor 232 is arranged at one end of the drive shaft 231, and the servo motor 232 is fixed on the frame 21. A first planetary reducer 233 is arranged between the motor shaft of the servo motor 232 and the drive shaft 231, and the motor shaft of the servo motor 232 is connected to the input shaft of the first planetary reducer 233, and the drive shaft 231 is connected to the output shaft of the first planetary reducer 233. When the servo motor 232 is started, the first planetary reducer 233 transmits the force of the motor shaft of the servo motor 232 to the drive shaft 231, thereby driving the drive shaft 231 to rotate.

[0080] Two upper pulleys 234 are arranged at intervals along the axial direction of the driving shaft 231 on the driving shaft 231, and the upper pulleys 234 are fixedly connected to the driving shaft 231. Two lower pulleys 235 are arranged at the bottom end of the frame 21, and the lower pulleys 235 are slewingly supported and connected to the frame 21. The upper pulleys 234 and the lower pulleys 235 are opposite to each other. An annular traction belt 236 is arranged between the upper pulleys 234 and the lower pulleys 235, and the traction belt 236 passes around the upper pulleys 234 and the lower pulleys 235. When the driving shaft 231 rotates, the upper pulley 234 drives the traction belt 236 to move, and the traction belt 236 is relatively fixed to the telescopic fork 22.

[0081] When the drive shaft 231 rotates forward, the traction belt 236 pulls the telescopic fork 22 to move upward. When the drive shaft 231 rotates reversely, the traction belt 236 labors the telescopic fork 22 to move downward. The height of the telescopic fork 22 is adjusted by controlling the drive shaft 231 to rotate forward and reverse.

[0082] Specifically, in this embodiment, the telescopic fork 22 includes a main frame 221 slidably connected to the frame body 21 and two telescopic arms 222 fixed to the main frame 221, and the two telescopic arms 222 are arranged side by side in a horizontal direction. There is a gap between the two telescopic arms 222, and the gap between the two telescopic arms 222 is used to accommodate the medicine decocting pot.

[0083] Furthermore, in the present embodiment, a secondary positioning mechanism 24 is provided between the two telescopic arms 222. When the two telescopic arms 222 are forking the medicine decoction pot, the secondary positioning mechanism 24 can fine-tune the position of the medicine decoction pot.

[0084] Specifically, the secondary positioning mechanism 24 includes a first clamping plate 241 and a second clamping plate 242. The first clamping plate 241 and the second clamping plate 242 are movably disposed between the two telescopic arms 222. The first clamping plate 241 and the second clamping plate 242 are disposed with a horizontal spacing therebetween.

[0085] A first linear optical axis 243 and a second linear optical axis 244 are disposed between the first clamping plate 241 and the second clamping plate 242. The first linear optical axis 243 and the second linear optical axis 244 are parallel to each other. The axial direction of the first linear optical axis 243 and the second linear optical axis 244 is disposed along the arrangement direction of the first clamping plate 241 and the second clamping plate 242.

[0086] Flange linear bearings are provided at both ends of the first linear optical axis 243 and the second linear optical axis 244, and the first linear optical axis 243 is slidably connected to the flange linear bearings. The flange linear bearings connected to the first linear optical axis are fixed to the main frame 221. The first linear optical axis 243 can move along its own axial direction on the flange linear bearings.

[0087] The second linear optical axis 244 is slidably connected to the flange linear bearing. The flange linear bearing connected to the second linear optical axis 244 is fixed on the main frame 221. The second linear optical axis 244 can move along its own axial direction on the flange linear bearing.

[0088] The first linear optical axis 243 passes through the first clamping plate 241 and the second clamping plate 242 in sequence. The first linear optical axis 243 and the first clamping plate 241 are slidably connected, and the first linear optical axis 243 and the second clamping plate 242 are fixedly connected.

[0089] The second linear optical axis 244 passes through the first clamping plate 241 and the second clamping plate 242 in sequence. The second linear optical axis 244 is fixedly connected to the first clamping plate 241 , and the second linear optical axis 244 is slidably connected to the second clamping plate 242 .

[0090] Transmission racks 245 are respectively disposed on the surfaces of one side opposite to the first linear optical axis 243 and the second linear optical axis 244. The transmission rack 245 on the first linear optical axis 243 is fixed to the first linear optical axis 243. The extension direction of the transmission rack 245 on the first linear optical axis 243 is arranged along the extension direction of the first linear optical axis 243. The transmission rack 245 on the second linear optical axis 244 is fixed to the second linear optical axis 244, and the extension direction of the transmission rack 245 on the second linear optical axis 244 is arranged along the extension direction of the second linear optical axis 244.

[0091] A transmission gear 246 is provided between the first linear optical axis 243 and the second linear optical axis 244 , and the transmission gear 246 is rotatably connected to the main frame 221 . The transmission gear 246 meshes with the transmission rack 245 on the first linear optical axis 243 and the transmission rack 245 on the second linear optical axis 244 .

[0092] In this embodiment, a driving cylinder 247 is provided on the side of the second clamping plate 242 facing away from the first clamping plate 241, and the piston rod of the driving cylinder 247 is parallel to the first linear optical axis 243 and the second linear optical axis 244. The driving cylinder 247 is fixed on the telescopic fork 22. The piston rod of the driving cylinder 247 is fixed to the second clamping plate 242. When the driving cylinder 247 is started, the piston rod of the driving cylinder 247 extends outward from the cylinder body of the driving cylinder 247, and the piston rod of the driving cylinder 247 pushes the second clamping plate 242 to approach the first clamping plate 241. Through the cooperation of the transmission rack 245 and the transmission gear 246, the first clamping plate 241 and the second clamping plate 242 move simultaneously and approach each other. When the piston rod of the driving cylinder 247 is gradually retracted from the extended state into the cylinder body of the driving cylinder 247, the first clamping plate 241 and the second clamping plate 242 move simultaneously and move away from each other.

[0093] The driving cylinder 247 can also be arranged on the side of the first clamping plate 241 facing away from the second clamping plate 242. When the driving cylinder 247 is arranged on the side of the first clamping plate 241 facing away from the second clamping plate 242, the piston rod of the driving cylinder 247 is fixed to the first clamping plate 242.

[0094] In this embodiment, a plurality of vertically arranged guide rails 25 are arranged on the surface of the frame 21, and the guide rails 25 are fixed on the frame 21. The main frame 221 of the telescopic fork 22 is provided with the same number of sliding seats 2211 as the guide rails 25, and the sliding seats 2211 are opposite to the guide rails 25 one by one. The sliding seats 2211 are clamped on the relative guide rails 25, and the sliding seats 2211 can move vertically along the extension direction of the guide rails 25. Through the cooperation between the sliding seats 2211 and the guide rails 25, the stability of the telescopic fork 22 can be increased when the telescopic fork 22 moves vertically.

[0095] Preferably, a QR code scanner 26 is provided on the main frame 221 of the telescopic fork 22, and the scanning area of ​​the QR code scanner 26 is located between the two telescopic arms 222. When the decoction pot is decocting medicinal materials, a QR code is generally pre-pasted on the outer surface of the decoction pot, and the prescription information of the medicinal materials in the decoction pot is recorded in the QR code. When the telescopic fork 22 forks the decoction pot, the QR code scanner 26 can scan the QR code of the decoction pot. The QR code scanner 26 scans the QR code on the decoction pot to ensure whether the medicinal materials decocted in the forked decoction pot match the prescription information set in the system.

[0096] Specifically, in this embodiment, the traction mechanism 3 includes a linear rack 31 fixed to one of the linear rails 11, and the extension direction of the linear rack 31 is parallel to the extension direction of the linear rail 11. The traction mechanism 3 also includes a driving gear 32 rotatably connected to the bottom of the stacker body 2, and the driving gear 32 is meshed with the linear rack 31. A driving motor 33 is provided on the stacker body 2, and a second planetary reducer 34 is provided between the motor shaft of the driving motor 33 and the driving gear 32, and the input shaft of the second planetary reducer 34 is connected to the motor shaft of the driving motor 33, and the output shaft of the second planetary reducer 34 is connected to the driving gear 32.

[0097] When the drive motor 33 is driven, the second planetary reducer 34 transmits the force applied by the motor shaft of the drive motor 33 to the drive gear 32, so that the drive gear 32 rotates. As the drive gear 32 rotates, the drive gear drives the stacker body 2 to move along the extension direction of the linear rack 31. By using the cooperation of the drive gear 32 and the linear rack 31 to drive the stacker body 2 to move, the moving position of the stacker body 2 can be more accurately controlled, and the error of the moving position of the stacker body 2 can be reduced.

[0098] Preferably, the linear rack 31 is a helical linear rack, and the driving gear 32 is a helical gear. By setting the driving gear 32 as a helical gear and the linear rack 31 as a helical linear rack, the impact between the teeth of the gear rack can be reduced through the oblique tooth design, so the transmission is smoother and the noise is less. At the same time, each pair of gear teeth of the helical gear enters and disengages from the meshing gradually, which reduces the load of each pair of gear teeth, improves the bearing capacity of the gear, and prolongs the service life.

[0099] The double-column stacker also includes a lubricating material supply mechanism 7, which is fixed on the frame 21. The lubricating material supply mechanism 7 is used to supply lubricating material between the driving gear 32 and the linear rack 31, between the linear track 11 and the moving seat 6, and between the guide track 25 and the sliding seat 2211. The lubricating material can be grease or lubricating oil.

[0100] The lubricating material supply mechanism 7 includes a container 71, an automatic lubricating pump 72 and a plurality of delivery pipelines 73. The interior of the container 71 is used to store the lubricating material, and the automatic lubricating pump 72 is connected to the interior of the container 71 through the pipeline, so as to extract the lubricating material stored in the container 71 through the pipeline.

[0101] The multiple delivery pipelines 73 include a first delivery pipeline 731 for delivering lubricating material between the driving gear 32 and the linear rack 31, a second delivery pipeline 732 for delivering lubricating material between the linear rail 11 and the moving seat 6, and a third delivery pipeline 733 for delivering lubricating material between the guide rail 25 and the sliding seat 2211.

[0102] Preferably, a lubricating material smearing member 8 is provided at the bottom of the stacker body 2, and the lubricating material smearing member 8 adopts a felt gear rotatably connected to the bottom of the stacker body 2. The felt gear is meshed with the driving gear 32. Since the felt gear is meshed with the driving gear 32, when the driving gear 32 rotates, the felt gear rotates synchronously.

[0103] The outlet of the first delivery pipeline 731 is opposite to the felt gear, and the lubricating material flowing out of the first delivery pipeline 731 flows onto the felt gear. When the driving gear 32 drives the felt gear to rotate, the lubricating material on the felt gear is smeared onto the surface of the driving gear 32. The lubricating material attached to the driving gear 32 is smeared onto the linear rack 31 as the driving gear 32 moves on the linear rack 31.

[0104] Specifically, the number of the second delivery pipelines 732 is the same as the number of the moving seats 6, and the second delivery pipelines 732 are opposite to the moving seats 6. The lubricating material flowing out of the second delivery pipelines 732 drips onto the moving seat 6. The lubricating material on the flow channel moving seat 6 gradually flows into the gap between the moving seat 6 and the linear track 11. When the moving seat 6 moves on the linear track 11, the moving seat 6 evenly applies the lubricating material on the linear track 11.

[0105] Specifically, the number of the third delivery pipelines 733 is the same as the number of the sliding seats 2211, and the third delivery pipelines 733 are opposite to the sliding seats 2211 one by one, and the third delivery pipelines 733 are hoses. The lubricating material flowing out of the third delivery pipeline 733 drips onto the sliding seat 2211, and the lubricating material flowing onto the sliding seat 2211 gradually flows into the gap between the sliding seat 2211 and the guide rail 25. When the sliding seat 2211 moves vertically along the guide rail 25, the sliding seat 2211 evenly applies the lubricating material on the guide rail 25.
