Then, the precise position of the barrel mouth is obtained by the visual inspection mechanism, and the IBC barrel capping mechanism or the 200LPE barrel capping mechanism is driven to screw off the barrel cover; Step 3: After the barrel cover is unscrewed, the filling mechanism will perform filling. After the filling is completed, the IBC barrel capping mechanism or the 200LPE barrel capping mechanism will screw back the barrel cover to complete the filling; Step 4: When the first detection shooting switch on the unloading roller conveyor line detects that there is no barrel at the unloading work position, the unloading port opening and closing door of the filling room opens, and the barrel is transported to the unloading port through the unloading roller conveyor line to wait for forklift transportation. When the first detection shooting switch detects that there is a barrel, the unloading port opening and closing door closes, and finally the whole filling process is completed.

[0019] (2) The present invention utilizes two capping mechanisms, only one of which is always in the process of capping, while the other is idle. A light source telescopic mechanism is installed in each of the two capping mechanisms. When one is in the process of capping, the other can insert the light source deep into the barrel body. This not only makes the two capping mechanisms cooperate with each other, but also uses a high-resolution camera to capture images of the barrel body to determine whether the barrel body quality meets the requirements. Therefore, while completing the filling, it is ensured that the barrel body quality meets the requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] Combine the following Figures 1 to 10 , the present invention is further described: like Figure 1As shown, the 200L PE barrel 11 is a common plastic container, which is widely used to store and transport various liquids, powders or granular materials. PE is the abbreviation of polyethylene, which has good chemical resistance, impact resistance and weather resistance, and is suitable for a variety of industrial applications. Its standard capacity is 200 liters, which is suitable for medium-scale storage and transportation needs. In the present invention, four 200L PE barrels 11 are placed on a forklift pallet as a group.

[0023] like Figure 2 As shown, an Intermediate Bulk Container (IBC) 12 is a large container used to store and transport liquid, powder or granular materials. It includes a container and a metal frame. The container is usually made of high-density polyethylene (HDPE) or stainless steel and is used to store liquid or solid materials. The metal frame is usually made of steel or aluminum and is used to protect the container and provide structural support.

[0024] like Figure 3-4 As shown, the fully automatic filling device compatible with different types of solvent barrels of the present invention includes a roller conveyor line 22, which is used to convey different types of solvent barrels into and out of a filling chamber 21; the solvent barrels include 200LPE barrels 11 and IBC ton barrels 12. A filling mechanism and two different types of opening mechanisms are provided in the filling chamber 21. Different opening mechanisms disassemble the corresponding barrel cover from the corresponding solvent barrel, and the filling mechanism then fills the solvent into the solvent barrel after the cover and barrel are separated, and the opening mechanism installs the barrel cover with the solvent barrel.

[0025] like Figure 4 As shown, the roller conveyor line 22 is composed of three parts: a loading roller conveyor line 22, a filling roller conveyor line 22 and a unloading roller conveyor line 22. The loading roller conveyor line 22 is provided with a second detection shooting switch 26, the filling roller conveyor line 22 is provided with a third detection shooting switch 27, a limit baffle, a side push cylinder assembly 24 and a blocking cylinder assembly 25, and the unloading roller conveyor line 22 is provided with a first detection shooting switch 23.

[0026] The filling method of the fully automatic filling device compatible with solvent barrels of different models of the present invention comprises the following steps: Step 1: Place the IBC barrel 12 or 200LPE barrel 11 on the loading roller conveyor line 22. When the third detection shooting switch 27 of the filling work station detects that there is no barrel and the second detection shooting switch 26 of the loading roller conveyor line 22 detects that there is a barrel at the loading work station, the loading port opening and closing door of the filling chamber 21 opens.

[0027] Step 2, the loading roller conveyor line 22 is opened, and after the barrel is transported to the filling roller conveyor line 22, the loading door is closed, and the barrel is roughly positioned by the blocking cylinder assembly 25 and the side push cylinder assembly 24, and then the precise position of the barrel mouth is obtained by the visual detection mechanism 33 and the IBC ton barrel capping mechanism 31 or the 200LPE barrel capping mechanism 32 is driven to unscrew the barrel cover.

[0028] Step 3: After the barrel cover is unscrewed, the filling mechanism performs filling. After the filling is completed, the IBC barrel capping mechanism 31 or the 200LPE barrel capping mechanism 32 screws the unscrewed barrel cover back to complete the filling.

[0029] Step 4: When the first detection shooting switch 23 on the unloading roller conveyor line 22 detects that there is no barrel at the unloading work position, the unloading port opening and closing door of the filling chamber 21 is opened, and the unloading roller conveyor line 22 is used to transport the barrel to the unloading port to wait for forklift transportation. When the first detection shooting switch 23 detects that there is a barrel, the unloading port opening and closing door is closed, and the entire filling process is finally completed.

[0030] like Figure 5 As shown, the filling chamber 21 is also provided with a visual inspection mechanism 33, a Y-axis moving mechanism 34 and an X-axis moving mechanism 35. The visual inspection mechanism 33, the cover opening mechanism and the filling mechanism are directly or indirectly connected to the Y-axis moving mechanism 34 and the Y-axis movement is realized by the driving mechanism of the Y-axis moving mechanism 34. The Y-axis moving mechanism 34 is connected to the X-axis moving mechanism 35, and the driving mechanism of the X-axis moving mechanism 35 realizes the X-axis movement of the visual inspection mechanism 33, the cover opening mechanism and the filling mechanism.

[0031] The Y-axis moving mechanism 34 and the X-axis moving mechanism 35 use servo motors to drive gears to move on racks and are guided by slide rails.

[0032] The lens of the visual inspection mechanism 33 moves to the middle of the barrel to take pictures to identify the exact position of the barrel mouth and control the IBC barrel capping mechanism 31, the 200LPE barrel capping mechanism 32 to align with the barrel mouth when capping and the filling mechanism 4 to fill, so as to realize capping and solvent filling.

[0033] like Figure 6As shown, the cover opening mechanism includes an IBC ton barrel cover screwing mechanism 31; the IBC ton barrel cover screwing mechanism 31 includes a pressing block 310, a bracket 311, a first lifting cylinder 312, a clamping cylinder 313, a claw assembly 314, a pressing plate 315, a first rotating shaft 316, a bearing ring assembly 317, a first reducer 318 and a first servo motor 319. The middle part of the claw assembly 314 is hinged to the pressing block 310, the upper part of the pressing block 310 is connected to the lower end of the first rotating shaft 316, the lower part of the pressing block 310 is used to press the barrel cover, the upper part of the claw assembly 314 is hinged to the ring sleeved on the first rotating shaft 316, and there is also a hinge point between the upper part of the claw assembly 314 and the middle part of the claw assembly 314; a spring is sleeved on the first rotating shaft 316 between the circular ring and the pressing block 310, and the clamping cylinder 313 acts on the pressing plate 315 to move downward, and the pressing plate 315 moves downward so that the circular ring moves downward The movement squeezes the spring at the same time, and the ring moves downward so that the lower end of the claw assembly 314 clamps the barrel cover; the upper end of the first rotating shaft 316 is connected to the first servo motor 319 through the first reducer 318, and the first servo motor 319 rotates the claw assembly 314 connected to the first rotating shaft 316 to achieve the removal or installation of the barrel cover; the first reducer 318 and the first servo motor 319 are installed on the bracket 311, and the first lifting cylinder 312 is connected to the bracket 311 to achieve the vertical movement of the claw assembly 314.

[0034] The filling method of the fully automatic filling device compatible with solvent barrels of different models of the present invention comprises the following steps: When the IBC ton barrel capping mechanism 31 is removing the barrel cover, the entire IBC ton barrel capping mechanism 31 is driven down by the first lifting cylinder 312. When the first lifting cylinder 312 is dropped to the lowest position and the circular plane of the pressure block 310 hits the barrel cover, the clamping cylinder 313 extends out, and transmits the cylinder thrust to the claw assembly 314 through the pressure plate 315, thereby clamping the barrel cover; the first rotating shaft 316 is driven to rotate by the first servo motor 319, the first reducer 318, and the bearing ring sleeve assembly 317, thereby driving the claw assembly 314 to rotate, realizing the lid loosening function, and after the barrel cover is completely separated from the barrel body, the first lifting cylinder 312 is retracted.

[0035] When the IBC ton barrel capping mechanism 31 is installing the barrel cover, the entire IBC ton barrel capping mechanism 31 is driven to descend through the first lifting cylinder 312. When the first lifting cylinder 312 descends to the lowest position, the barrel cover clamped by the claw assembly 314 is driven to rotate through the first servo motor 319. When the torque reaches the set value of the first servo motor 319, the clamping cylinder 313 retracts, and the claw assembly 314 releases the barrel cover through the restoring force of the spring. The first lifting cylinder 312 retracts to complete the capping.

[0036] The first rotating shaft 316 is connected to the first speed reducer 318 through the bearing sleeve assembly 317. The bearing sleeve assembly 317 allows the first rotating shaft 316 to move up and down in a small range therein to prevent the claw assembly 314 from being damaged by the cylinder pressure when the cap is screwed.

[0037] like Figure 7 As shown, the cover opening mechanism includes a 200LPE barrel cover screwing mechanism 32; the 200LPE barrel cover screwing mechanism 32 includes a second servo motor 320, a second reducer 321, a second lifting cylinder 322, a guide sleeve buffer compression spring 323, a floating guide sleeve 324, a cover screwing head assembly 325, a cover screwing head clamping cylinder 326, a cover screwing head clamping spring 327, a cover screwing head clamping block 328, a universal coupling 329, a sprocket chain assembly 3210, a second rotating shaft 3211 and a height adjustment cylinder 3212.

[0038] The floating guide sleeve 324 has a cavity that can cover and guide the vertical edge of the barrel cover. The lower end of the capping head assembly 325 is located in the cavity of the floating guide sleeve 324, which fits the barrel cover and transmits rotational force to the barrel cover. The upper end of the capping head assembly 325 is connected to the lower end of the second rotating shaft 3211 through a universal coupling 329. The upper end of the second rotating shaft 3211 is connected to the second reducer 321 through a sprocket chain assembly 3210. The second servo motor 320 is connected to the second reducer 321. A fixing plate 3214 is provided on the mounting bracket 3213. The universal coupling 329 passes through the passage hole on the fixing plate. The straight rod at the upper end of the head assembly 325 passes through the circular plate at the top of the floating guide sleeve 324, and a guide sleeve buffer compression spring 323 is provided between the circular plate and the fixed plate to ensure that the capping head assembly 325 and the floating guide sleeve 324 are concentric with the barrel cover; the straight rod sleeve of the capping head assembly 325 is provided with a capping head clamping spring 327, and the capping head clamping spring 327 is limited between the pressure block at the lower end of the capping head assembly 325 and the capping head clamping block 328 at the upper end, and the capping head clamping cylinder 326 acts on the capping head clamping block 328, and transmits the spring force to the capping head assembly 325 through the capping head clamping spring 327 so that it can be stuck in the barrel cover.

[0039] A groove or a protrusion is provided at the bottom of the screw capping head assembly 325, which matches with the protrusion or the groove on the barrel cover, so that the screw capping head assembly 325 and the barrel cover can be snap-fitted.

[0040] It also includes a second lifting cylinder 322 and a height adjustment cylinder 3212. The second lifting cylinder 322 can drive the entire 200LPE barrel capping mechanism 32 to move in the vertical direction; the cylinder rod of the height adjustment cylinder 3212 is connected to the second rotating shaft 3211, which can enable the second rotating shaft 3211 to move in the vertical direction to adapt to 200LPE barrels of different heights.

[0041] The reason why the IBC barrel capping mechanism 31 uses the claw assembly 314 and the 200LPE barrel capping mechanism 32 uses the capping head assembly 325 for capping is that the two are for different barrel cap mechanisms: the barrel cap of the IBC barrel is thicker and has multiple ribs on the side, so each claw can be clamped between two adjacent ribs. There is a groove on the top of the 200LPE barrel, and the protrusion on the top of the capping head assembly 325 can be stuck in the groove and the protrusion can be clamped by the elastic groove. Therefore, the two capping mechanisms are different to suit different barrel caps.

[0042] The filling method of the fully automatic filling device compatible with solvent barrels of different models of the present invention comprises the following steps: When the 200LPE barrel capping mechanism 32 is removing the barrel cap, the entire 200LPE barrel capping mechanism 32 is driven to descend by the second lifting cylinder 322. During the descent of the second lifting cylinder 322, the floating guide sleeve 324 first contacts the barrel cap of the 200L PE barrel, the guide sleeve buffer compression spring 323 is compressed, and the capping head assembly 325 is guided; When the second lifting cylinder 322 drops to the lowest position, the capping head assembly 325 engages with the barrel cover, and the second rotating shaft 3211 is driven to rotate by the second servo motor 320, the second reducer 321, and the sprocket chain assembly 3210. The second rotating shaft 3211 transmits power to the capping head assembly 325 through the universal coupling 329, thereby driving the barrel cover to rotate and realize the cap loosening function; after the barrel cover is completely detached, the second lifting cylinder 322 retracts; When the 200LPE barrel capping mechanism 32 is installing the barrel cover, the entire 200LPE barrel capping mechanism 32 is driven to descend by the second lifting cylinder 322. When the second lifting cylinder 322 descends to the lowest position, the second rotating shaft 3211 is driven to rotate by the second servo motor 320, the second reducer 321, and the sprocket chain assembly 3210. The second rotating shaft 3211 transmits power to the capping head assembly 325 through the universal coupling 329 to drive the barrel cover to rotate; when the torque reaches the set value of the second servo motor 320, the second servo motor 320 stops rotating, the second lifting cylinder 322 retracts, and the installation of the barrel cover is completed.

[0043] like Figure 8As shown, the filling mechanism includes a material pipe 41 and a rodless cylinder 47. The rodless cylinder 47 is connected to the material pipe 41 so that the material pipe 41 can enter the barrel mouth of the solvent barrel. A filling valve cylinder 46 is provided at the upper end of the material pipe 41. The filling valve cylinder 46 is connected to the plug 42 through a push-pull rod 45. The push-pull rod 45 is located in the material pipe 41. When the filling valve cylinder 46 retracts the cylinder rod, the push-pull rod 45 drives the plug 42 to move upward to close the outlet of the material pipe 41. When the filling valve cylinder 46 releases the cylinder rod, the push-pull rod 45 drives the plug 42 to move downward to open the outlet of the material pipe 41; a feed flange 43 is provided on the material pipe 41 to connect with the feeding pipe, and a gas pipe joint 44 is provided on the material pipe 41 to connect with the gas pipe. The high-pressure gas in the gas pipe presses the material in the material pipe 41 out of the material pipe 41.

[0044] The working principle of the filling mechanism is as follows: when the filling port of the material pipe 41 is aligned with the barrel mouth, the rodless cylinder 47 moves vertically to drive the material pipe 41 into the barrel, at this time, the feed valve opens, the filling valve cylinder 46 extends, drives the push-pull rod 45 and the plug 42 to move downward, separates the plug 42 from the material pipe 41, and begins to inject solvent into the barrel. When the weight of the solvent reaches the set value of the weighing sensor, the feed flange 43 is closed, and the air pipe blows the material pipe 41 to blow the residual solvent in the material pipe 41 into the barrel. After the air blowing is completed, the filling valve cylinder 46 retracts, drives the push-pull rod 45 and the plug 42 to move upward, so that the plug 42 and the material pipe 41 are pressed tightly to close the filling port, and the rodless cylinder 47 drives the filling assembly to withdraw from the barrel, and the filling is completed.

The driving motor 51 rotates the screw rod 52, and the nut 53 and the movable sleeve 54 can move axially along the screw rod 52 so that the high-power LED lamp 55 leaves the pressing block 310 or the screw capping head assembly 325 and enters the IBC ton barrel 11 or the 200LPE barrel 12; after the IBC ton barrel screw capping mechanism 31 grabs the barrel cover, the light source telescopic mechanism in the 200LPE barrel screw capping mechanism 32 enables the high-power LED lamp 55 to enter the IBC ton barrel; after the 200LPE barrel screw capping mechanism 32 grabs the barrel cover, the light source telescopic mechanism in the IBC ton barrel screw capping mechanism 31 enables the high-power LED lamp 55 to enter the 200LPE barrel.
