Description

Technical Field

[0001] The invention belongs to the technical field of filling machines, in particular to a can feeding mechanism of a filling machine. Background Art

[0002] A filling machine is a type of packaging equipment and is also one of the most commonly used packaging equipment. From the perspective of material packaging, it can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of the degree of production automation, it can be divided into semi-automatic filling machines and fully automatic filling production lines. At present, when a fully automatic liquid filling machine is working, the conveyor belt transports the tank to be filled to the designated position, and then the liquid is injected into the tank through the filling head, and then transported by the conveyor belt.

[0003] In actual filling operations, a conveyor belt is required to accurately transport the can body to a designated position to ensure accurate filling through the filling head. However, when the conveyor belt is transporting the can body, it will inevitably accelerate, decelerate and brake. In this process, the can body located on the surface of the conveyor belt is prone to move relative to the conveyor belt due to inertia, causing the transported can body to deviate from the predetermined position when the conveyor belt stops, which in turn makes it difficult for the filling head to accurately inject the liquid into the tank body during the subsequent filling operation. For this reason, a robot arm needs to be set at the filling position to further position the tank body to ensure accurate docking between the tank body and the filling head. However, this adjustment method involves a transportation process and an adjustment process, which not only increases the preparation cost of the filling machine but also complicates the filling procedure, affecting the filling efficiency.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7 As shown, a can feeding mechanism of a filling machine according to an embodiment of the present invention comprises a workbench 1, a pair of conveyor belts 11 are symmetrically arranged on the top of the workbench 1 based on the center line, a loading plate 12 is arranged on the top surface of the conveyor belt 11, and a magnetic metal block is arranged at the center position inside the loading plate 12; a plurality of placement grooves 13 are provided on the top surface of the loading plate 12, and the inner diameter of the placement groove 13 is the same as the diameter of the can body to be filled; a rectangular through hole 3 is provided at the center position of the top surface of the workbench 1, a pair of slide grooves 31 are symmetrically arranged on both sides of the rectangular through hole 3, a slider is slidably connected inside the slide groove 31, a slide plate 32 is arranged at the top of the slider, an electromagnet 33 is arranged at the center of the top surface of the slide plate 32, and a receiving plate 36 is arranged on the top of the electromagnet 33; the top surface of the receiving plate 36 is at the same height as the top surface of the conveyor belt 11; a power supply 34 is installed on the top surface of the slide plate 32, and a conductive wire is arranged between the power supply 34 and the electromagnet 33; a connecting rod is provided on the bottom surface of the slide plate 32; and a filling block 35 is arranged at the bottom end of the connecting rod; A screw rod 4 is arranged below the rectangular through hole 3, and the end of the screw rod 4 is rotatably connected to a mounting plate, the top of the mounting plate is mounted on the bottom surface of the workbench 1, and an output motor 41 is arranged on the side of the mounting plate, and the output end of the output motor 41 is connected to the end of the screw rod 4, and the length of the filling block 35 is the same as the pitch of the spiral blades on the surface of the screw rod 4; initially, the filling block 35 is inserted into the gap between the spiral blades on the surface of the screw rod 4; a bracket 2 is arranged above the center position of the workbench 1, and a filling assembly 21 is arranged on the bottom surface of the bracket 2; the filling assembly 21 is used for filling the tank to be filled; When the embodiment of the present invention is in use, the manipulator places the loading plate 12 on the top surface of the conveyor belt 11, and the placement groove 13 on the top surface of the loading plate 12 is inserted with the can body to be filled, with the can mouth pointing upwards; then the conveyor belt 11 is controlled to rotate, and the conveyor belt 11 moves the loading plate 12 towards the receiving plate 36. Since the top surface of the receiving plate 36 is at the same height as the top surface of the conveyor belt 11, when the loading plate 12 is separated from the conveyor belt 11, the receiving plate 36 will receive the loading plate 12. Then, as the loading plate 12 moves on the receiving plate 36, when the magnetic metal block (not shown in the drawings of the specification) at the center of the loading plate 12 moves to the position just above the electromagnet 33, the power supply 34 is electrically conductive. The electromagnet 33 is energized, and the electromagnet 33 is energized to attract the magnetic metal block at the center of the loading plate 12, thereby limiting the loading plate 12 to the top of the receiving plate 36, and then the output motor 41 is started, and the output motor 41 drives the screw rod 4 to rotate, and the spiral blades on the surface of the screw rod 4 rotate synchronously. When the spiral blades rotate, the filling block 35 inserted in the gap between the spiral blades is pushed and moved by the spiral blades, and then the filling block 35 drives the slide plate 32 to slide on the top surface of the workbench 1 through the linkage rod, and when the slide plate 32 moves, the slider on the bottom slides inside the slide groove 31, thereby ensuring that the slide plate 32 moves in a straight line, and the receiving plate 36 is driven to move synchronously, and then moves to the filling component 2 1, the output motor 41 stops rotating, and then the can body on the loading plate 12 is filled with liquid through the filling assembly 21. When the filling is completed, the output motor 41 continues to rotate, and the filling block 35 drives the slide plate 32 to continue to move, thereby driving the loading plate 12 on the top of the receiving plate 36 to move synchronously. Since the length of the loading plate 12 is greater than the length of the receiving plate 36, when the receiving plate 36 moves to a position close to the end of another conveyor belt 11 and stops, part of the loading plate 12 will move to the top surface of the conveyor belt 11. As the conveyor belt 11 rotates, the conveyor belt 11 drives the loading plate 12 to move to the top surface of the conveyor belt 11 through the friction between the conveyor belt 11 and the loading plate 12 ; At this time, the power supply 34 no longer supplies power to the electromagnet 33, and the electromagnet 33 will not limit the movement of the loading plate 12; then the output motor 41 rotates in the opposite direction to reset the receiving plate 36 to the initial position, and then repeats the receiving of the loading plate 12 to continue the filling operation; during the entire filling process, the can body is first transported by the conveyor belt 11, and then transported by the receiving plate 36. The position of the receiving plate 36 is controlled by the number of twists of the screw rod 4, and the loading plate 12 that receives the can body is magnetically restricted. Therefore, the can body can be accurately transported to the filling position, and there is no need to use a robot for adjustment, which reduces the preparation cost of the filling machine and simplifies the filling procedure to avoid affecting the filling efficiency.

[0023] The two ends of the filling block 35 are rotatably connected with balls (not shown in the drawings of the specification). When the spiral blade on the surface of the spiral rod 4 rotates, the balls replace the filling block 35 to contact the surface of the spiral blade; when the spiral blade drives the filling block 35 to move, the balls at both ends of the filling block 35 will continue to press against the surface of the spiral blade, which can eliminate the gap between the filling block 35 and the spiral blade, improve the accuracy of the movement of the filling block 35 driven by the spiral blade, and reduce the friction between the filling block 35 and the surface of the spiral blade, thereby reducing the loss of the spiral blade during use and increasing the service life.

[0024] like Figures 8 to 9 As shown, an inclined surface 5 is provided at the end of the receiving plate 36 close to the conveyor belt 11; when the loading plate 12 moves to the top surface of the receiving plate 36, since the conveyor belt 11 is made of deformable material, when the mass of the can body is large, the loading plate 12 may compress the conveyor belt 11 to cause it to deform, resulting in the bottom surface height of the loading plate 12 being lower than the top surface height of the receiving plate 36. Therefore, an inclined surface 5 is provided at the end of the receiving plate 36 close to the conveyor belt 11. When the bottom surface height of the loading plate 12 is lower than the top surface height of the receiving plate 36, the end of the loading plate 12 will be pressed against the inclined surface 5, and then slide to the top surface of the receiving plate 36 through the inclined surface 5, completing the position transfer of the loading plate 12 from the conveyor belt 11 to the receiving plate 36, thereby avoiding jamming during movement.

[0025] like Figures 5 to 9 As shown, a plurality of grooves 6 are provided on the top surface of the receiving plate 36, and a support roller 61 is arranged inside the groove 6. The end of the support roller 61 is rotatably connected to a receiving bar 64. A pair of first hydraulic cylinders 62 are arranged on the top surface of the slide plate 32, and a connecting member 63 is arranged between the top of the output end of the first hydraulic cylinder 62 and the receiving bar 64; when the loading plate 12 partially moves to the top surface of the receiving plate 36, the first hydraulic cylinder 62 is started, and the receiving bar 64 is driven to move upward through the connecting member 63, and the receiving bar 64 drives the support roller 61 to move upward in the groove 6, and partially moves the support roller 61 to the top of the groove 6, thereby propping up the loading plate 12. After that, when the loading plate 12 moves on the support roller 61, the support roller 61 rotates, thereby reducing the friction resistance encountered by the loading plate 12 during movement, which is beneficial to improving the smoothness of the movement of the loading plate 12 on the top surface of the receiving plate 36.

[0026] like Figures 10 to 12As shown, a pair of air extraction grooves 7 are symmetrically provided on the bottom surface of the loading plate 12 based on the center line, and a suction cup 71 is arranged inside the air extraction groove 7, and the bottom end of the suction cup 71 is at the same height as the groove opening of the air extraction groove 7; a pair of air pumps 72 are arranged on the top surface of the loading plate 12 and directly above the air extraction groove 7, and the input end of the air pump 72 passes through the interior of the air extraction groove 7 and is connected with the suction cup 71; in the process of the loading plate 12 entering the top of the receiving plate 36 and detaching from the top of the receiving plate 36, the air pump 72 is started, and the air pump 72 evacuates air from the suction cup 71 in the air extraction groove 7, so that the suction cup 71 is adsorbed to the top surface of the conveyor belt 11, thereby increasing the driving force of the conveyor belt 11 on the loading plate 12, ensuring the process of the loading plate 12 stably entering the top surface of the receiving plate 36 and stably detaching from the top surface of the receiving plate 36; it should be pointed out that the pair of suction cups 71 of the loading plate 12 are alternately evacuated to avoid obstruction to the movement of the loading plate 12.

[0027] like Figure 12 to Figure 14 As shown, a plurality of pressure plates 8 are arranged in an annular shape inside the placement groove 13, and a second hydraulic cylinder 81 is arranged on one side of the pressure plate 8 close to the annular inner wall of the placement groove 13, and the output end of the second hydraulic cylinder 81 is connected to the pressure plate 8, and the shell part of the second hydraulic cylinder 81 is installed on the inner wall of the placement groove 13; for tank bodies of different sizes, by setting the pressure plate 8, when the tank body is placed inside the placement groove 13, the second hydraulic cylinder 81 is started, and the pressure plate 8 is pushed to move toward the surface of the tank body and stops when the pressure is generated, and the output of the second hydraulic cylinder 81 is pre-set based on the size of the tank body. Therefore, for tank bodies of different sizes, the placement groove 13 can be restricted in conjunction with the pressure plate 8 to improve the range of adaptation to the tank body.

[0028] A layer of rubber sheet is provided on the surface of the pressure plate 8 (not shown in the drawings of the specification); when the pressure plate 8 is close to the tank body, the rubber sheet will replace the pressure plate 8 to press against the surface of the tank body. The rubber sheet can increase the friction between the tank body and the tank body, thereby improving the stability of the tank body being restricted.

[0029] A plurality of inclined plates 82 are installed on the top of the pressure plate 8, and the inclined plates 82 are inclined away from the center of the placement groove 13; the bottom end of the inclined plate 82 is connected to the top end of the pressure plate 8; in actual use, for the semi-automatic filling mechanism; the tank body is placed inside the placement groove 13 by the staff. During the placement process, when the position of the pressure plate 8 is controlled in advance, the staff needs to align the tank body with the center of the placement groove 13 and move it downward. When a deviation occurs, the inclined plate 82 will receive the tank body and guide the tank body to move downward between the pressure plates 8, which is convenient for the staff to operate.

[0030] like Figure 1 to Figure 2As shown, a pair of limit plates 83 are arranged on the top surface of the conveyor belt 11 for conveying cans before filling. The limit plates 83 include a horizontal portion and an inclined portion. The spacing between the horizontal portions of the pair of limit plates 83 is the same as the width of the loading plate 12. When the manipulator places the loading plate 12 on the top surface of the conveyor belt 11, it is necessary to place the loading plate 12 at the center of the conveyor belt 11. By setting a pair of limit plates 83, a connecting frame connected to the workbench 1 is arranged on the side of the limit plates 83, and the horizontal spacing between the pair of limit plates 83 is the same as the width of the loading plate 12. The spacing between the parts is the same as the width of the loading plate 12, and the center line between a pair of limit plates 83 coincides with the center line of the conveyor belt 11. Therefore, the loading plate 12 transported by the conveyor belt 11 will inevitably pass between the horizontal parts of a pair of limit plates 83 when moving. When there is an error in the placement of the loading plate 12, the pair of limit plates 83 support and guide the loading plate 12 through the inclined parts to enter between the horizontal parts of the pair of limit plates 83 for correction, thereby ensuring the position accuracy of the loading plate 12 and helping to improve the overall filling accuracy.

[0031] A capping assembly 9 and a labeling assembly 91 are arranged above the conveyor belt 11 for transporting the filled cans; the capping assembly 9 and the labeling assembly 91 are used for capping and labeling the filled cans; when the loading plate 12 drives the filled can body to move to the bottom of the capping assembly 9 and the labeling assembly 91, the capping assembly 9 and the labeling assembly 91 will respectively perform capping and labeling operations on the can body to ensure the integrity of the overall equipment function.

[0032] During operation, the manipulator places the loading plate 12 on the top surface of the conveyor belt 11, and the placement groove 13 on the top surface of the loading plate 12 is inserted with the can to be filled, with the can mouth pointing upwards; then the conveyor belt 11 is controlled to rotate, and the conveyor belt 11 moves the loading plate 12 towards the receiving plate 36. Since the top surface of the receiving plate 36 is at the same height as the top surface of the conveyor belt 11, when the loading plate 12 is separated from the conveyor belt 11, the receiving plate 36 will receive the loading plate 12. Then, as the loading plate 12 moves on the receiving plate 36, when the magnetic metal block (not shown in the drawings of the specification) at the center of the loading plate 12 moves to the position just above the electromagnet 33, the power supply 34 energizes the electromagnet 33 through the conductive wire, and the electromagnet 33 is energized to attract the magnetic metal block at the center of the loading plate 12. Then the feeding plate 12 is restricted to the top of the receiving plate 36, and then the output motor 41 is started, the output motor 41 drives the screw rod 4 to rotate, and the spiral blades on the surface of the screw rod 4 rotate synchronously. When the spiral blades rotate, the filling block 35 inserted in the gap between the spiral blades is pushed to move by the spiral blades, and then the filling block 35 drives the slide plate 32 to slide on the top surface of the workbench 1 through the connecting rod, and when the slide plate 32 moves, the slider on the bottom slides inside the slide groove 31, thereby ensuring that the slide plate 32 moves in a straight line, and the receiving plate 36 is driven to move synchronously. When it moves to the filling position just below the filling component 21, the output motor 41 stops rotating, and then the can body on the feeding plate 12 is filled with liquid through the filling component 21. When the filling is completed, the output motor 41 continues to rotate, and the filling is completed. The filling block 35 drives the slide plate 32 to continue moving, and then drives the loading plate 12 on the top of the receiving plate 36 to move synchronously. Since the length of the loading plate 12 is greater than the length of the receiving plate 36, when the receiving plate 36 moves to a position close to the end of another conveyor belt 11 and stops, part of the loading plate 12 will move to the top surface of the conveyor belt 11. As the conveyor belt 11 rotates, the conveyor belt 11 drives the loading plate 12 to move to the top surface of the conveyor belt 11 through the friction between the conveyor belt 11 and the loading plate 12; at this time, the power supply 34 no longer supplies power to the electromagnet 33, and the electromagnet 33 will not limit the movement of the loading plate 12; then the output motor 41 rotates in the opposite direction to reset the receiving plate 36 to the initial position, and then repeats the receiving of the loading plate 12 to continue the filling operation; during the entire filling process, the can body first passes through It is transported by the conveyor belt 11 and then by the receiving plate 36. The position of the receiving plate 36 is controlled by the number of twisting turns of the spiral rod 4. The loading plate 12 that receives the can body is limited by magnetic force. Therefore, the can body can be accurately transported to the filling position, and there is no need to use a robot for adjustment, which reduces the preparation cost of the filling machine and simplifies the filling procedure to avoid affecting the filling efficiency. When the spiral blade drives the filling block 35 to move, the balls at both ends of the filling block 35 will continue to press against the surface of the spiral blade, which can eliminate the gap between the filling block 35 and the spiral blade, improve the accuracy of the spiral blade driving the filling block 35 to move, and reduce the friction between the filling block 35 and the surface of the spiral blade, thereby reducing the loss of the spiral blade during use and increasing the service life.

[0033] When the loading plate 12 moves to the top surface of the receiving plate 36, since the conveyor belt 11 is made of deformable material, when the mass of the can body is large, the loading plate 12 may compress the conveyor belt 11 to cause it to deform, resulting in the bottom surface height of the loading plate 12 being lower than the top surface height of the receiving plate 36. Therefore, an inclined surface 5 is provided at the end of the receiving plate 36 close to the conveyor belt 11. When the bottom surface height of the loading plate 12 is lower than the top surface height of the receiving plate 36, the end of the loading plate 12 will press against the inclined surface 5, and then slide to the top surface of the receiving plate 36 through the inclined surface 5, completing the loading plate 12 from The conveyor belt 11 is transferred to the position on the receiving plate 36 to avoid jamming during movement; when the loading plate 12 partially moves to the top surface of the receiving plate 36, the first hydraulic cylinder 62 is started, and the receiving bar 64 is driven to move upward through the connecting piece 63, and the receiving bar 64 drives the support roller 61 to move upward in the groove 6, and the support roller 61 is partially moved to the top of the groove 6, thereby propping up the loading plate 12. After that, when the loading plate 12 moves on the support roller 61, the support roller 61 rotates, reducing the friction resistance of the loading plate 12 during movement, which is conducive to improving the loading plate 12 in the receiving The smoothness of the movement of the top surface of the plate 36; in the process of the loading plate 12 entering the top of the receiving plate 36 and detaching from the top of the receiving plate 36, the air pump 72 is started, and the air pump 72 evacuates the suction cup 71 in the suction groove 7, so that the suction cup 71 is adsorbed to the top surface of the conveyor belt 11, thereby increasing the driving force of the conveyor belt 11 on the loading plate 12, ensuring the loading plate 12 stably enters the top surface of the receiving plate 36 and stably detaches from the top surface of the receiving plate 36; it should be pointed out that the pair of suction cups 71 of the loading plate 12 are alternately evacuated to avoid obstruction to the movement of the loading plate 12; For tanks of different sizes, by setting a pressure plate 8, when the tank is placed in the placement groove 13, the second hydraulic cylinder 81 is started, the pressure plate 8 is pushed to the surface of the tank and stops when pressure is generated. The output of the second hydraulic cylinder 81 is pre-set based on the size of the tank. Therefore, for tanks of different sizes, the placement groove 13 can be restricted by the pressure plate 8 to improve the range of adaptation to the tank; when the pressure plate 8 is close to the tank, the rubber sheet will replace the pressure plate 8 to press on the surface of the tank, and the rubber sheet can increase the friction between the rubber sheet and the tank, thereby improving the stability of the restricted tank.

[0034] In actual use, for the semi-automatic filling mechanism; the can body is placed in the placement slot 13 by the staff. During the placement process, when the position of the pressure plate 8 is controlled in advance, the staff needs to align the can body with the center of the placement slot 13 and move it downward. When a deviation occurs, the inclined plate 82 will receive the can body and guide the can body to move downward between the pressure plates 8, which is convenient for the staff to operate; when the manipulator places the loading plate 12 on the top surface of the conveyor belt 11, it is necessary to place the loading plate 12 at the center position of the conveyor belt 11, by setting a pair of limit plates 83, and the side of the limit plate 83 is provided with a connecting frame connected to the workbench 1, and the horizontal parts between the pair of limit plates 83 are spaced apart from the loading plate 1 2 has the same width, and the center line between the pair of limit plates 83 coincides with the center line of the conveyor belt 11, so the loading plate 12 transported by the conveyor belt 11 will inevitably pass between the horizontal parts of the pair of limit plates 83 when moving. When there is an error in the placement of the loading plate 12, the pair of limit plates 83 receive and guide the loading plate 12 to enter between the horizontal parts of the pair of limit plates 83 through the inclined parts for correction, so as to ensure the position accuracy of the loading plate 12, which is conducive to improving the overall filling accuracy; wherein, when the loading plate 12 drives the filled can body to move to the bottom of the capping assembly 9 and the labeling assembly 91, the capping assembly 9 and the labeling assembly 91 will respectively perform capping and labeling operations on the can body, so as to ensure the integrity of the overall equipment function.
