[0047] The application will be further described below Figures 1 to 10 The application will be further described below

[0048] As Figure 1 shown, the 200L PE barrel 11 is a common plastic container, widely used for storing and transporting various liquid, powder or granular materials. PE is the abbreviation of Polyethylene, this material has good chemical resistance, impact resistance and weather resistance, suitable for various industrial applications. Its capacity is standard capacity of 200 liters, suitable for medium-scale storage and transportation needs. In this application, four 200L PE barrels 11 are placed on a forklift pallet as a group.

[0049] As Figure 2 shown, the IBC ton barrel 12 (Intermediate Bulk Container, IBC for short) is a large container for storing and transporting 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, used for storing liquid or solid materials. The metal frame is usually made of steel or aluminum, used to protect the container and provide structural support.

[0050] As Figures 3-4 shown, the application is compatible with different models of solvent barrels, including a drum conveying line 22 for conveying different models of solvent barrels into and out of the filling chamber 21; the solvent barrels include 200L PE barrels 11 and IBC ton barrels 12. The filling chamber 21 is provided with a filling mechanism and two different types of cap opening mechanisms, the different cap opening mechanisms will disassemble the corresponding barrel cap from the corresponding solvent barrel, the filling mechanism will fill the solvent into the solvent barrel after the cap is separated, and the cap opening mechanism will install the barrel cap on the solvent barrel.

[0051] As Figure 4 shown, the drum conveying line 22 is composed of three parts: the drum conveying line 22 for feeding, the drum conveying line 22 for filling and the drum conveying line 22 for discharging. The second detection reflection switch 26 is arranged on the drum conveying line 22 for feeding, the third detection reflection switch 27, the limiting baffle, the side pushing cylinder assembly 24 and the blocking cylinder assembly 25 are arranged on the drum conveying line 22 for filling, and the first detection reflection switch 23 is arranged on the drum conveying line 22 for discharging.

[0052] The filling method of the full-automatic filling device compatible with different models of solvent barrels of the application comprises the following steps:

[0053] Step 1: Place the IBC ton 12 or 200LPE ton 11 onto the feeding roller conveyor line 22. When the third detection photoelectric switch 27 of the filling station detects that there is no ton and the second detection photoelectric switch 26 of the feeding roller conveyor line 22 detects that there is a ton at the feeding station, the opening and closing door of the feeding port of the filling chamber 21 is opened.

[0054] Step 2: The feeding roller conveyor 22 is turned on. After the barrel is transported to the filling roller conveyor 22, the feeding opening and closing door is closed. The barrel is coarsely positioned by the blocking cylinder assembly 25 and the side push cylinder assembly 24. Then, the precise position of the barrel opening is obtained by the vision inspection mechanism 33 and the IBC ton barrel capping mechanism 31 or the 200LPE barrel capping mechanism 32 is driven to unscrew the barrel cap.

[0055] Step 3: After the lid is unscrewed, the filling mechanism will fill the container. After filling is completed, the IBC ton container capping mechanism 31 or the 200LPE container capping mechanism 32 will screw the unscrewed lid back on to complete the filling.

[0056] Step 4: When the first detection photoelectric switch 23 on the unloading roller conveyor line 22 detects that there is no barrel at the unloading work position, the unloading port door of the filling chamber 21 opens and the barrel is transported to the unloading port through the unloading roller conveyor line 22 to wait for the forklift to transfer. When the first detection photoelectric switch 23 detects that there is a barrel, the unloading port door closes, and the entire filling process is finally completed.

[0057] like Figure 5 As shown, the filling chamber 21 is also equipped with a vision inspection mechanism 33, a Y-axis moving mechanism 34, and an X-axis moving mechanism 35. The vision inspection mechanism 33, the cap opening mechanism, and the filling mechanism are all directly or indirectly connected to the Y-axis moving mechanism 34 and move in the Y direction through the drive 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 drive mechanism of the X-axis moving mechanism 35 realizes the X-axis movement of the vision inspection mechanism 33, the cap opening mechanism, and the filling mechanism.

[0058] The Y-axis moving mechanism 34 and the X-axis moving mechanism 35 are driven by servo motors to move gears on racks and pinions, and are guided by slide rails.

[0059] The lens of the visual inspection mechanism 33 moves to the middle of the barrel to take pictures and identify the accurate position of the barrel opening. It controls the IBC barrel capping mechanism 31, the 200LPE barrel capping mechanism 32 to align with the barrel opening when capping and the filling mechanism 4 to fill, so as to realize capping and solvent filling.

[0060] like Figure 6As shown, the opening mechanism includes an IBC container capping mechanism 31; the IBC container capping mechanism 31 includes a pressure block 310, a bracket 311, a first lifting cylinder 312, a clamping cylinder 313, a claw assembly 314, a pressure 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 pressure block 310, the upper part of the pressure block 310 is connected to the lower end of the first rotating shaft 316, the lower part of the pressure block 310 is used to press the container lid, the upper part of the claw assembly 314 is hinged to a ring fitted 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 fitted on the first rotating shaft 316 between the ring and the pressure block 310, the clamping cylinder 313 actuates the pressure plate 315 downward, the pressure plate 315 moves downward, causing the ring to move downward. The movement compresses the spring, causing the ring to move downwards and clamp the bottom of the claw assembly 314 onto the lid. The upper end of the first rotating shaft 316 is connected to the first servo motor 319 via the first reducer 318. The first servo motor 319 causes the claw assembly 314 connected to the first rotating shaft 316 to rotate, thereby enabling the removal or installation of the lid. The first reducer 318 and the first servo motor 319 are mounted on the bracket 311, and the first lifting cylinder 312 is connected to the bracket 311 to enable the vertical movement of the claw assembly 314.

[0061] The present invention provides a filling method for a fully automatic filling device compatible with different types of solvent tanks, comprising the following steps:

[0062] When the IBC ton container capping mechanism 31 removes the container lid, the first lifting cylinder 312 drives the entire IBC ton container capping mechanism 31 to descend. When the first lifting cylinder 312 descends to the lowest position and the circular plane of the pressure block 310 touches the container lid, the clamping cylinder 313 extends and transmits the cylinder thrust to the claw assembly 314 through the pressure plate 315, thereby clamping the container lid. The first servo motor 319, the first reducer 318, and the bearing ring assembly 317 drive the first rotating shaft 316 to rotate, thereby driving the claw assembly 314 to rotate, realizing the lid release function. After the container lid is completely separated from the container body, the first lifting cylinder 312 retracts.

[0063] When the IBC ton container capping mechanism 31 is installing the container lid, the first lifting cylinder 312 drives the entire IBC ton container capping mechanism 31 to descend. When the first lifting cylinder 312 descends to the lowest position, the first servo motor 319 drives the lid held by the claw assembly 314 to rotate. 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 lid through the restoring force of the spring. The first lifting cylinder 312 retracts, completing the cap tightening process.

[0064] The first rotating shaft 316 is connected with the first speed reducer 318 through the bearing sliding sleeve assembly 317. The bearing sliding sleeve assembly 317 allows the first rotating shaft 316 to move up and down in a small range, preventing the damage of the threads of the barrel caused by the pawl assembly 314 when the cap is screwed and the cylinder pressure is borne.

[0065] As shown in FIG. 2, the cap opening mechanism includes a 200LPE barrel cap screwing mechanism 32. The 200LPE barrel cap screwing mechanism 32 includes a second servo motor 320, a second speed reducer 321, a second lifting cylinder 322, a guide sleeve buffer spring 323, a floating guide sleeve 324, a cap screwing head assembly 325, a cap screwing head pressing cylinder 326, a cap screwing head pressing spring 327, a cap screwing head pressing block 328, a universal coupling 329, a sprocket and chain assembly 3210, a second rotating shaft 3211, and a height adjusting cylinder 3212. Figure 7 The floating guide sleeve 324 has a cavity capable of covering and guiding the vertical edge of the barrel cap. The lower end of the cap screwing head assembly 325 is embedded in the cavity of the floating guide sleeve 324 to fit the barrel cap and transmit the rotating force to the barrel cap. The upper end of the cap screwing head assembly 325 is connected with the lower end of the second rotating shaft 3211 through the universal coupling 329. The upper end of the second rotating shaft 3211 is connected with the second speed reducer 321 through the sprocket and chain assembly 3210. The second servo motor 320 is connected with the second speed reducer 321. The mounting bracket 3213 is provided with a fixed plate 3214. The universal coupling 329 passes through the through hole of the fixed plate. The straight rod of the upper end of the cap screwing head assembly 325 passes through the circular plate at the top of the floating guide sleeve 324. The guide sleeve buffer spring 323 is arranged between the circular plate and the fixed plate to ensure that the cap screwing head assembly 325 and the floating guide sleeve 324 are concentric with the barrel cap. The straight rod of the cap screwing head assembly 325 is sleeved with the cap screwing head pressing spring 327. The cap screwing head pressing spring 327 is limited between the pressing block at the lower end of the cap screwing head assembly 325 and the cap screwing head pressing block 328 at the upper end. The cap screwing head pressing cylinder 326 acts on the cap screwing head pressing block 328. The spring force is transmitted to the cap screwing head assembly 325 through the cap screwing head pressing spring 327, so that the cap screwing head assembly 325 can be clamped into the barrel cap.

[0066] The bottom of the cap screwing head assembly 325 is provided with a groove or a protrusion, which matches with the protrusion or the groove on the barrel cap, so that the cap screwing head assembly 325 and the barrel cap can be clamped.

[0067] The second lifting cylinder 322 and the height adjusting cylinder 3212 are further included. The second lifting cylinder 322 can drive the entire 200LPE barrel cap screwing mechanism 32 to move in the vertical direction. The cylinder rod of the height adjusting cylinder 3212 is connected with the second rotating shaft 3211, so that the second rotating shaft 3211 can move in the vertical direction to adapt to 200LPE barrels of different heights.

[0068]

[0069] ​The reason why the IBC ton barrel cap mechanism 31 uses the claw assembly 314 and the 200L PE barrel cap mechanism 32 uses the cap head assembly 325 to cap is that both are for different barrel cap mechanisms: the barrel cap of the IBC ton barrel is thicker, and multiple convex ribs are distributed on the side, so each claw can be clamped between two adjacent convex ribs. While the 200L PE barrel top has a groove, the protrusion at the top of the cap head assembly 325 can be clamped in the groove, and the protrusion can be clamped by the elastic groove. Therefore, the two cap mechanisms are not the same to adapt to different barrel caps.

[0070] The present application is compatible with the filling method of the full-automatic filling device for different models of solvent barrels, comprising the following steps:

[0071] When the 200L PE barrel cap mechanism 32 is disassembling the barrel cap, the second lifting cylinder 322 drives the entire 200L PE barrel cap mechanism 32 to descend, and the floating guide sleeve 324 first contacts the barrel cap of the 200L PE barrel during the descent of the second lifting cylinder 322, the guide sleeve buffer spring 323 is compressed, and the cap head assembly 325 is guided;

[0072] When the second lifting cylinder 322 is lowered to the lowest position, the cap head assembly 325 is engaged with the barrel cap, the second servo motor 320, the second speed reducer 321, and the chain wheel and chain assembly 3210 drive the second rotating shaft 3211 to rotate, the second rotating shaft 3211 transmits power to the cap head assembly 325 through the universal joint 329, thereby driving the rotation of the barrel cap, realizing the function of loosening the cap; after the barrel cap is completely separated, the second lifting cylinder 322 is retracted;

[0073] When the 200L PE barrel cap mechanism 32 is installing the barrel cap, the second lifting cylinder 322 drives the entire 200L PE barrel cap mechanism 32 to descend, and when the second lifting cylinder 322 is lowered to the lowest position, the second servo motor 320, the second speed reducer 321, and the chain wheel and chain assembly 3210 drive the second rotating shaft 3211 to rotate, the second rotating shaft 3211 transmits power to the cap head assembly 325 through the universal joint 329, thereby driving the rotation of the barrel cap; 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 is retracted, and the installation of the barrel cap is completed.

[0074] As Figure 8As shown, the filling mechanism includes a tube 41 and a rodless cylinder 47, the rodless cylinder 47 is connected with the tube 41 so that the tube 41 can enter the barrel opening of the solvent barrel, the upper end of the tube 41 is provided with a filling valve cylinder 46, the filling valve cylinder 46 is connected with the plug 42 through a push-pull rod 45, the push-pull rod 45 is located in the tube 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 tube 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 tube 41; The tube 41 is provided with a feeding flange 43 connected with a feeding pipe, the tube 41 is provided with a gas pipe joint 44 connected with a gas pipe, the high-pressure gas in the gas pipe press the material in the tube 41 out of the tube 41.

[0075] The working principle of the filling mechanism is as follows: when the filling port of the tube 41 is aligned with the barrel opening, the rodless cylinder 47 vertically moves to drive the tube 41 to extend into the barrel, at this time the feeding valve is opened, the filling valve cylinder 46 extends to drive the push-pull rod 45 and the plug 42 to move downward, so that the plug 42 is separated from the tube 41, and the solvent begins to be injected into the barrel, when the weight of the solvent reaches the set value of the weighing sensor, the feeding flange 43 is closed, the gas pipe blows the tube 41 to blow the residual solvent in the tube 41 into the barrel. After the gas blowing is completed, the filling valve cylinder 46 retracts to drive the push-pull rod 45 and the plug 42 to move upward, so that the plug 42 is pressed tightly with the tube 41 to close the filling port, the rodless cylinder 47 drives the filling assembly to exit outside the barrel, and the filling is completed.

The driving motor 51 rotates the lead screw 52, the nut 53 and the moving sleeve 54 can move axially along the lead screw 52, so that the high-power LED lamp 55 enters the IBC ton barrel 11 or the 200L PE barrel 12 away from the pressing block 310 or the cap screwing head assembly 325; after the IBC ton barrel cap screwing mechanism 31 grasps the barrel cap, the light source telescopic mechanism in the 200L PE barrel cap screwing mechanism 32 makes the high-power LED lamp 55 enter the IBC ton barrel; after the 200L PE barrel cap screwing mechanism 32 grasps the barrel cap, the high-power LED lamp 55 enters the 200L PE barrel through the light source telescopic mechanism in the IBC ton barrel cap screwing mechanism 31, and a high-resolution camera is arranged around the IBC ton barrel or the 200L PE barrel to collect light changes on the barrel wall, and a control unit judges whether there is a crack or a barrel wall thinning according to the light changes.
