DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0034] Example 1

[0035] Reference Figure 1 As shown, a bag canning device of the present invention comprises:

[0036] The lifting mechanism comprises: a first clamping assembly 8, a second clamping assembly 7, a lifting drive assembly, and a limit plate 36. The first clamping assembly 8 is driven and connected to two groups of corresponding first support rods 9. The second clamping assembly 7 is connected to the output end of the lifting drive assembly. The second clamping assembly 7 is driven and connected to two groups of corresponding second support rods 11 arranged on one side of the first support rod 9. The limit plates 36 are arranged on both sides of the second support rods 11 and form a lifting channel for the bag body 3 to be filled to pass through.

[0037] The canning mechanism comprises: a contour seat 10, a cover plate 26, a crank arm driving assembly, a first pushing assembly, and a second pushing assembly. The contour seat 10 is arranged on one side of the second support rod 11, the cover plate 26 is connected to the output end of the crank arm driving assembly and can be driven to cover the contour seat 10, the cover plate 26 and the contour seat 10 enclose a press-fitting space for accommodating a bag body 3 to be filled with a can, the size of the press-fitting space gradually decreases along the direction of the can body to be bagged on the first side of the contour seat 10, the first pushing assembly is movably arranged in the press-fitting space, the second pushing assembly is connected to the output end of the first pushing assembly, the contour seat 10 is provided with a plurality of first strip grooves 19 adapted to the second support rod 11, the size of the press-fitting space is larger than the second pushing assembly and smaller than the first pushing assembly, the first pushing assembly can be fitted to the inner wall of the second side of the contour seat 10, and the second pushing assembly is adapted to the can body to be filled.

[0038] The bag canning device described in the present invention, when it is necessary to carry out canning operation on the bag 3 to be canned, the bag is placed on a receiving rack composed of the first support rods 9, the two sets of second support rods 11 are closed and close to the bottom of the first support rods 9, the first support rods 9 are driven to open by the first clamping assembly 8, so that the bag falls onto the receiving rack composed of the second support rods 11, the bag is driven to move downward in the lifting space by the driving assembly, the bag descends with the descent of the support rods, and is limited by the limiting plate 36 until the bag reaches the vicinity of the profiling seat 10, the second support rods 11 are opened to make the bag fall into the profiling seat 10, and the cover plate 26 is driven to close by the crank arm driving assembly. On the contour seat 10, a sealed press-fitting space is formed surrounding the circumference of the bag body, so that the first pushing component moves in the press-fitting space from the second side of the contour seat 10 toward the first side, and the second pushing component is tightly fitted to the inner wall of the second side of the contour seat 10, which can prevent the bag body from being stuck between the second pushing component and the contour seat 10. Since the size of the press-fitting space on the first side of the contour seat 10 along the direction toward the can body to be bagged is gradually reduced, the first pushing component is stopped when pushing the second pushing component to the second side, and the press-fitting space on the second side of the bag contour seat 10 is gradually squeezed into a shape that matches the can body, and the bag body continues to be pushed into the can body to be bagged through the second pushing component.

[0039] The first clamping assembly 8 drives and connects two groups of corresponding first support rods 9. The first clamping assembly 8 can be, for example, a pneumatic clamp or an electric clamp, etc. When the first clamping assembly 8 receives a corresponding control signal, it can make the two groups of first support rods 9 dock to form a material receiving rack or separate and move away. The second clamping assembly 7 and the second support member have the same principle.

[0040] It also includes a third clamping assembly 4, which is driven and connected to an opening and closing plate 5. The opening and closing plate 5, the first support rod 9 and the second support rod 11 are arranged in sequence from top to bottom. The limiting plate 36 is provided with a plurality of second strip grooves adapted to the second support rod 11. The limiting plate 36 is provided with a plurality of through holes adapted to the first support rod 9. The first strip grooves 19 and the second strip grooves correspond to each other continuously one by one. The structure of the third clamping assembly 4 can be similar to that of the first clamping assembly 8, for example, a pneumatic or electric clamping structure is adopted. It mainly plays the role of driving the opening and closing plates 5. The two groups of opening and closing plates 5 are closed to form a closed receiving platform, which not only provides additional buffering positions and optimizes the canning rhythm, but also can form a shielding above to prevent foreign objects from falling. Photoelectric sensors are set on both sides of the opening and closing plates 5. When a bag is detected, it opens, so that the bag falls on the second support rod 11 for buffering, waiting for the first support rod 9 to receive the material, and forms an empty space on the opening and closing plates 5 to wait for the next batch of bag materials to be received, preventing multiple batches of bags from mixing, and providing waiting time and buffering positions for matching the incoming material speed and the canning speed. The width and depth of the second strip groove are designed according to the size of the second support rod 11, so that the second support rod 11 can move up and down smoothly in the second strip groove during the lifting process to guide and give way. The continuous correspondence between the first strip groove 19 and the second strip groove ensures that the movement path of the second support rod 11 is continuously coordinated during the lifting operation. The through hole on the limit plate 36 is used to adapt the first support rod 9. The diameter of the through hole is slightly larger than the outer diameter of the first support rod 9 to allow the first support rod 9 to pass smoothly. The edge of the through hole may be smoothed, for example, by chamfering or rounding, to reduce the friction resistance of the first support rod 9 when passing through the through hole.

[0041] The lifting drive assembly includes: a lifting motor 12, a driving screw 13 connected to the output end of the lifting motor 12, a screw pair adapted to the screw, and a lifting frame 6 connected to the screw pair. The second clamping assembly 7 is connected to the lifting frame 6, and the screw pair is adapted to the driving screw 13, and is composed of components such as a nut and a slider. The internal thread of the nut is matched with the external thread of the screw. When the lifting motor 12 is started, the output shaft of the motor starts to rotate, driving the driving screw 13 connected thereto to rotate synchronously. Since the screw pair and the driving screw 13 are adapted to each other, the rotational movement of the screw causes the nut of the screw pair to produce a linear motion. Under the guidance of the guide rail, the slider in the screw pair moves smoothly along the linear direction, thereby driving the lifting frame 6 connected to the screw pair to perform a linear lifting motion, such as driven by a belt, a chain, etc. The second clamping assembly 7 is connected to the lifting frame 6, and the lifting motion of the lifting frame 6 is directly transmitted to the second clamping assembly 7. The second clamping assembly 7 then drives the second support rod 11 connected thereto to perform a lifting motion.

[0042] The profiling seat 10 includes: a ring portion 16, a concave portion 15 and a movable portion 33, wherein the ring portion 16 is arranged on one side close to the can body to be loaded, and the concave portion 15 is arranged on the other side of the ring portion, and the movable portion 33 is detachably installed on both sides of the concave portion 15 and extends upward, and the profiling seat 10 is provided with a plurality of first strip grooves 19 in the vertical direction, and the first strip grooves 19 correspond to the second strip grooves, and the concave portion 15, the movable portion 33 and the cover plate 26 enclose a press-fitting space, and the ring portion 16 encloses a guide space, and the press-fitting space and the guide space have the same size along the vertical plane; the ring portion 16 is embedded with a narrowing portion 32, and the narrowing portion 32 encloses a shaping space whose size gradually decreases toward the direction of the can body to be loaded, and the shaping space and the guide space constitute a press-fitting space, The press-fitting space is narrowed on the first side of the profiling seat 10 to form a shaping space. The ring portion 16 is located on the side close to the can body to be loaded and on the second side of the profiling seat 10. The shape of the ring portion 16 is annular. The concave portion 15 is arranged on the other side of the annular portion. Its shape is an inwardly concave structure, and it has an end surface adapted to the cover plate 26 at the top. When it is in contact with the cover plate 26, it forms an accommodating space adapted to be slightly larger than the can body. Mounting structures are arranged on both sides of the concave portion 15 for detachably mounting the movable portion 33. A guiding inclined surface is provided at the top of the movable portion 33, and the movable portion 33 itself is made of wear-resistant material, which can provide a guiding function and increase wear resistance. It can be removed and replaced after excessive wear. The top of the movable portion 33 and the bottom of the limiting plate 36 form a tongue adapted. The cover plate 26 is provided with a groove 27 adapted to the concave portion 15 to enclose a guiding space.

[0043] The bag is then gradually reshaped into a shape that is more similar to the shape of the can body to be filled.

[0044] A shaping seat 17 is embedded on the side of the ring portion 16 close to the can body to be loaded, and a guide ring 29 is provided on the side of the shaping seat 17 close to the can body to be loaded. The inner wall of the guide ring 29 is provided with an inclined surface which gradually expands outward toward the can body to be loaded. The size of the intersection line between the shaping seat 17 and the inner circle of the guide ring 29 is the same as the size of the outer circle of the can body to be loaded. The shape of the shaping seat 17 is adapted to the local shape of the ring portion 16 to ensure a tight fit. The inclination angle of the inclined surface is determined according to factors such as the material and shape of the bag body and the shape of the can body to be loaded. The can body is guided by the guide ring 29 and surrounded by the outer peripheral side of the can body to prevent the bag body from squeezing the can body and causing tearing during canning.

[0045] The first pushing assembly includes: a first cylinder 22 arranged on one side of the shaping seat 17, a telescopic arm 21 connected to the output end of the first cylinder 22, and a first piston disc 30 connected to the end of the telescopic arm 21. The first piston disc 30 can fit the inner wall of the guide space, and the shape of the first piston disc 30 is designed to match the inner wall of the guide space. Since the first strip groove 19 passes through the profiling seat 10 and is connected to the guide space, the first piston and the first cylinder 22 are selected based on factors such as the thrust, working stroke and working frequency required in the canning process. The selection of the first cylinder 22 is determined based on factors such as the thrust, working stroke and working frequency required in the canning process. The edge of the first piston disc 30 is chamfered or rounded to reduce the friction resistance in the process of fitting with the inner wall of the space and prevent scratching the bag body. When the bag body reaches the position where it needs to be pushed, the first cylinder 22 starts to work, and the gas in the cylinder drives the piston to move, and the piston drives the telescopic arm 21 to extend. The telescopic arm 21 transmits power to the first piston disc 30, and the first piston disc 30 begins to move in the guide space toward the shaping space. Since the first piston disc 30 can fit the inner walls of the shaping space and the guide space, during the movement, the first piston disc 30 contacts the bag body and applies a thrust to the bag body, causing the bag body to move toward the inside of the shaping space. At the same time, the first piston disc 30 causes the bag body to gradually change its shape according to the shape of the space during the pushing process, and begins to perform preliminary shaping until the first piston disc 30 abuts against the wall on one side of the shaping space.

[0046] The second pushing assembly includes: a second cylinder 28 provided on the telescopic arm 21, a second piston disc 18 connected to the output end of the second cylinder 28, the second piston disc 18 can be fitted to the inner wall of the narrowing portion 32 close to the side of the can to be loaded, the size of the second piston disc 18 is slightly smaller than the guide ring 29, the first piston disc 30 is provided with a receiving groove 31 adapted to the second piston disc 18, the function of the receiving groove 31 is to provide space for the second piston disc 18 to form a flat surface during the canning process when the first pushing assembly and the second pushing assembly work together, in the process of the first piston disc 30 pushing the bag body for preliminary shaping, the receiving groove 31 can accommodate the second piston disc 18, so that the two can push the bag body in the same vertical plane, and as the first piston disc 30 continues to push, the bag body gradually approaches the final shaping and pushing stage. When the bag body reaches a certain position, the first piston disc 30 stops pushing or slows down the pushing speed. At this time, the second cylinder 28 starts to work, and the second piston disc 18 extends out from the accommodating groove 31 of the first piston disc 30. After the second piston disc 18 extends out, under the push of the second cylinder 28, it fits the inner wall of the narrowing portion 32 close to the side of the can body to be loaded and continues along the inner wall of the narrowing portion 32, passing through the inner side of the narrowing portion 32 to push the bag body into the can body.

[0047] A bracket 20 is provided on one side of the profiling seat 10, and the crank arm driving assembly includes: a third cylinder 23 provided on one side of the profiling seat 10, a first arm 24 with one end hinged to the output end of the third cylinder 23 and the other end rotatably connected to the bracket 20, a second arm 25 with one end fixedly connected to the first arm 24 and the other end connected to the cover plate 26, an angle is formed between the extension directions of the first arm 24 and the second arm 25, the bracket 20 is fixed to the base of the device by bolt connection or welding, and the piston inside the third cylinder 23 moves linearly under the action of air pressure. When compressed air is introduced into the air inlet of the cylinder, the piston moves forward; when the compressed air is released or the air is exhausted to the exhaust port, the piston returns under the action of a spring or an external load, and a joint bearing is used to connect at the hinge with the output end of the third cylinder 23, and this connection method can ensure that the first arm 24 can rotate flexibly within a certain range. The rotation connection part with the bracket 20 can be connected by an axle pin, and a rolling bearing is installed on the axle pin to reduce the friction resistance during rotation. When the piston of the third cylinder 23 moves, the first arm 24 rotates around the connection point with the bracket 20. Since the first arm 24 is hinged with the output end of the third cylinder 23, it can adjust its own angle according to the movement direction and stroke of the piston. The second arm 25 is integrally formed with the first arm 24. Since the second arm 25 is connected with the first arm 24, when the first arm 24 rotates under the drive of the third cylinder 23, the second arm 25 will move with the first arm 24 and transmit the movement to the cover plate 26. There is an angle between the extension directions of the first arm 24 and the second arm 25, so that the cover body can rotate around the pin. The limit plate 36 includes a first limit plate 36 with a second strip groove on both sides along the radial direction of the profiling seat 10, and a front limit plate 35 close to one side of the tank body. When the cover plate 26 is opened, it forms a rear limit plate 36. The three groups of limit plates 36 enclose a lifting space.

[0048] Also include a flip displacement assembly 1, which includes: a suction cup that can adsorb the tank body to be loaded, a flip assembly connected to the suction cup and used to drive the suction cup to rotate and be coaxial with the profiling seat 10, and a displacement assembly 1 connected to the flip assembly and used to drive it to approach or move away from the profiling seat 10, and the adsorption principle is based on the negative pressure principle. After the suction cup contacts the surface of the tank body, the air in the suction cup is extracted by an external device such as a vacuum pump, so that a negative pressure environment is formed inside the suction cup. Under the effect of the external atmospheric pressure, the suction cup is tightly adsorbed on the surface of the tank body, the flip assembly is driven by a cylinder to rotate around the drive shaft, the crank arm is fixedly connected to the drive shaft, the suction cup and its bracket 20 are fixedly connected to the drive shaft, thereby rotating with the drive shaft, the displacement assembly 1 is a screw rod driven displacement assembly 1, the screw rod cooperates with a nut, and the nut is fixedly connected to the bracket 20 of the flip assembly. The motor drives the screw rod to rotate, and the nut moves linearly on the screw rod. The flip assembly is connected to the output end of the screw rod driven displacement assembly 1, thereby driving the flip assembly to approach or move away from the profiling seat 10.

[0049] Example 2

[0050] This embodiment discloses a control method, which uses a bag-filling canning device as described in Embodiment 1 to put a bag-filled body into a can-filled body, comprising the following steps:

[0051] Step S1: provide a plurality of canned bags 3 to be filled, and place the canned bags 3 into the contour seat 10 by using a lifting mechanism; the first clamping assembly 8 and the second clamping assembly 7 of the lifting mechanism respectively operate the first support rod 9 and the second support rod 11. After the receiving rack composed of the first support rod 9 receives the canned bags 3 to be filled, the first clamping assembly 8 drives the first support rod 9 to open, so that the bags fall onto the receiving rack composed of the second support rod 11. The lifting drive assembly (such as a motor-screw mechanism) is started, driving the second support rod 11 to move downward, and the first support rod 9 moves downward synchronously. The bag body descends in the lifting channel formed by the limit plate 36 along with the support rod, and the limit plate 36 limits the support rod through the through hole (adapting to the first support rod 9) and the strip groove (adapting to the second support rod 11) opened therein, ensuring that the bag body accurately reaches the vicinity of the contour seat 10 and falls into the contour seat 10.

[0052] Step S2: using the cover body and the contour seat 10 to surround a plurality of bags 3 to be filled with cans on the second side of the contour seat 10; the piston of the third cylinder 23 extends to push the first arm 24 to rotate around the connection point with the bracket 20, and the second arm 25 moves with the first arm 24, driving the cover plate 26 to move toward the contour seat 10 and cover the contour seat 10.

[0053] Step S3: using the first pushing assembly and the second pushing assembly to drive the bag body 3 to be filled with cans, so that it is driven from the second side of the contour seat 10 to the first side;

[0054] The first pushing assembly starts to work. The gas in the first cylinder 22 pushes the piston to move, and the piston drives the telescopic arm 21 to extend, and the first piston disc 30 at the end of the telescopic arm 21 moves from the second side to the first side of the contour seat 10 in the press-fitting space.

[0055] The first piston disc 30 is fitted to the inner wall of the shaping space and the guide space, and applies a thrust to the bag body during the movement, so that the bag body moves toward the first side. Since the size of the press-fitting space on the first side of the contour seat 10 in the direction toward the can body to be bagged gradually decreases, the bag body is squeezed by the first piston disc 30 and the inner wall of the space during the pushing process, and begins to be shaped, and its shape gradually adjusts to a shape suitable for loading into the can body, and the second pushing assembly continues to work. The second piston disc 18 is located in the receiving groove 31 of the first piston disc 30.

[0056] Step S4: using the second pushing assembly to drive the bag body 3 to be filled into the can body to be filled.

[0057] After the bag is pushed into the guide space by the first pushing assembly, the first piston disc 30 stops pushing, and the second cylinder 28 starts pushing the second piston disc 18 out of the receiving groove 31 of the first piston disc 30. The second piston disc 18 fits the inner wall of the narrowing portion 32 close to the side of the can to be loaded, and the bag is pushed from the first side of the contour seat 10 into the can to be loaded under the push of the second cylinder 28. Since the size of the second piston disc 18 is slightly smaller than the guide ring 29, it can smoothly pass through the guide ring 29 area where the bag has passed before, and finally accurately push the bag into the can to be loaded, completing the entire canning process.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention.
