Description

Technical Field

[0001] This invention relates to a structure in which the upper bag and the handover tray work simultaneously. Background Technology

[0002] In the domestic market, large food packages are generally made of woven bags. However, with rising labor costs, many rice producers are opting for fully automated packaging equipment. In existing fully automated packaging equipment, after the filling mechanism completes filling a bag, the bag is conveyed to the next station by the feeding mechanism. Then, the swing arm bag-loading mechanism swings the next bag onto the filling mechanism. In this process, the feeding mechanism and the swing arm bag-loading mechanism cannot be mechanically linked; they rely solely on sensors to detect the bag positions of the filling and feeding mechanisms. The swing arm bag-loading mechanism then uses its own power source to perform the swinging bag-loading action, resulting in poor synchronization and stability. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a structure in which the upper bag and the handover bag work simultaneously.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a structure for synchronous operation of bag feeding and bag handover, including a filling mechanism, a bag feeding mechanism is arranged below the filling mechanism, and a swing arm bag feeding mechanism is arranged behind the bag feeding mechanism; the bag feeding mechanism includes a bag feeding seat that moves back and forth, a connecting rod is hinged on the bag feeding seat, the other end of the connecting rod is hinged to the swing arm of the swing arm bag feeding mechanism, and the top end of the swing arm is hinged to the frame through a rotating shaft.

[0005] Preferably, the bag delivery mechanism includes a fixed frame, on which a bag delivery seat is mounted and reciprocated by an electric mechanism. A bag clamping assembly is located above the bag delivery seat, and a bag support assembly is located below it. The bag clamping assembly includes a left clamp and a right clamp, both of which are driven by a first drive mechanism to move up and down and reciprocate left and right.

A bag support plate is located below the bag support assembly.

[0006] Preferably, the package feeding seat and the fixed frame are connected by a sliding block slide rail moving pair extending in the front-rear direction. The electric mechanism includes a servo motor, the output end of which is fixedly connected to a crank. The crank is hinged to a connecting rod, which is hinged to the package feeding seat, forming a crank-slider mechanism.

[0007] Preferably, both the left and right grippers are pneumatic fingers, and the first drive mechanism includes a lifting cylinder fixedly connected to the package feeding seat. The top of the double piston rod of the lifting cylinder is fixedly connected to an adapter plate. The adapter plate is equipped with an electric cylinder that can extend and retract left and right. The piston rod of the electric cylinder is fixedly connected to the cylinder body of the corresponding pneumatic finger. The pneumatic finger and the adapter plate are connected by a sliding block slide rail moving pair extending in the left and right direction.

[0008] Preferably, both the left and right pallets are arc-shaped, and the second drive mechanism includes a bag-holding cylinder. The double piston rods of the bag-holding cylinder extend to the left and right and are fixedly connected to the corresponding pallets. The cylinder bodies of the bag-holding cylinders are fixedly connected to the adapter frame. The adapter frame and the bag-feeding seat are connected by a vertical slider rail moving pair.

[0009] Preferably, the bag support plate is located below the left support plate and the right support plate.

[0010] Preferably, the bag support plate is driven to rise and fall by a drive mechanism.

[0013] Compared with the prior art, the present invention has the following advantages: a connecting rod is hinged to the bag feeding seat, and the other end of the connecting rod is hinged to the swing arm of the swing arm bag feeding mechanism. The top of the swing arm is hinged to the frame through a rotating shaft. When the bag feeding seat moves forward to feed the bag, the bag feeding seat controls the swing arm to move synchronously through the connecting rod. The swing arm of the swing arm bag feeding mechanism swings the bag with the bag opening facing upward to the bottom of the filling mechanism. The bag feeding and the swing arm bag feeding have strong linkage, good synchronization and stability. The swing arm bag feeding mechanism does not need to be set up with a separate swing arm power source.

[0027] like Figures 1-9 As shown, this embodiment provides a structure in which bag feeding and bag handover work synchronously, including a filling mechanism 1, a bag feeding mechanism 2 is provided below the filling mechanism, and a swing arm bag feeding mechanism 3 is provided behind the bag feeding mechanism; the bag feeding mechanism includes a bag feeding seat that moves back and forth, a connecting rod 4 is hinged to the bag feeding seat, the other end of the connecting rod is hinged to the swing arm 5 of the swing arm bag feeding mechanism, and the top end of the swing arm is hinged to the frame through a rotating shaft.

[0028] When the bag feeding seat moves forward to feed the bag, the bag feeding seat controls the swing arm to move in sync via the connecting rod. The swing arm of the bag feeding mechanism swings the bag with the opening facing upwards and feeds the bag to the bottom of the filling mechanism.

[0029] In this embodiment of the invention, the bag-feeding mechanism includes a fixed frame A1, on which a bag-feeding seat A2 is mounted, which is driven by an electric mechanism to perform reciprocating sliding motion. A bag-clamping assembly is mounted above the bag-feeding seat, and a bag-supporting assembly is mounted below it. The bag-clamping assembly includes a left gripper A3 and a right gripper A4, both of which are driven by a first driving mechanism to perform lifting and lowering and reciprocating sliding motion. The bag-supporting assembly includes a left support plate A5 and a right support plate A6, both of which are driven by a second driving mechanism to perform lifting and lowering and reciprocating sliding motion. A bag-supporting plate A7 is mounted below the bag-supporting assembly.

[0030] In this embodiment of the invention, the package feeding seat and the fixed frame are connected by a slider slide rail moving pair A8 extending in the front-back direction. The electric mechanism includes a servo motor A9, the output end of which is fixedly connected to a crank A10. The crank is hinged to a connecting rod A11, which is hinged to the package feeding seat, and the whole assembly forms a crank slider mechanism.

[0031] In this embodiment of the invention, both the left and right grippers are pneumatic fingers. The first driving mechanism includes a lifting cylinder A12 fixedly connected to the package feeding seat. The top of the double piston rod of the lifting cylinder is fixedly connected to a transition plate A13. The transition plate is equipped with a left-right telescopic electric cylinder A14. The piston rod of the electric cylinder is fixedly connected to the cylinder body of the corresponding pneumatic finger. The pneumatic fingers and the transition plate are connected by a sliding block slide rail moving pair extending in the left-right direction.

[0032] In this embodiment of the invention, both the left and right support plates are arc-shaped. The second driving mechanism includes a bag-supporting cylinder A15, with its double piston rods extending laterally and fixedly connected to the corresponding support plates. The cylinder bodies of the bag-supporting cylinders are fixedly connected to a transfer frame A16. The transfer frame and the bag-feeding seat are connected via a vertically oriented slider-rail sliding pair. The transfer frame can be adjusted for height by an electric push rod, cylinder, hydraulic cylinder, or ball screw pair.

[0033] In this embodiment of the invention, the bag support plate is located below the left support plate and the right support plate.

[0034] In this embodiment of the invention, the bag support plate is driven to rise and fall by a driving mechanism, which is a cylinder.

[0035] In this embodiment of the invention, a support bag assembly is also installed on the swing arm.

[0036] In this embodiment of the invention, a package delivery conveyor 6 is connected to the front of the package delivery mechanism.

[0037] In this embodiment of the invention, the bag-clamping assembly includes a rotating shaft 7 mounted on a swing arm. The rotating shaft is driven to rotate by a power source. A bag-clamping clearance cylinder 8 is fixedly connected to the rotating shaft. The piston rod of the bag-clamping clearance cylinder faces downward and is fixedly connected to a bag-clamping cylinder 9. L-shaped bag-clamping plates 10 are fixedly connected to the piston rods at both ends of the bag-clamping cylinder. Bag-clamping mechanical fingers 11 are fixedly connected to the swing arms at both ends of the bag-clamping plates.

[0038] In this embodiment of the invention, the conveyor belt of the package conveyor has two sections that drive in the left and right directions. The two sections of the conveyor belt are driven separately and connected at adjacent ends. A photoelectric switch 12 is provided at the adjacent end.

[0039] In this embodiment of the invention, the filling mechanism includes a filling frame 13, on which a filling cylinder 14 with the filling port facing downwards is provided. The filling cylinder is symmetrically equipped with bag-sorting mechanical fingers 15 on the left and right sides of the filling port. The bag-sorting mechanical fingers are all driven by bag-sorting cylinders 16 to perform left and right reciprocating translation adjustment. The left and right extension stroke of the bag-sorting cylinders is adjustable so as to adjust according to large or small bags. The filling cylinder is symmetrically hinged with V-shaped swing blocks 17 on the front and rear sides of the filling port. The lower end of each V-shaped swing block is fixedly connected with a bag-clamping rubber 18, and the upper end of each V-shaped swing block is connected to a bag-clamping cylinder 19 to control the swing of the V-shaped swing blocks.

[0040] The working method of this structure, which synchronizes the upper bag with the handover bag, includes the following steps:

[0041] like Figure 5 As shown, after the packaging bag is opened and sent to the swing arm bag-loading mechanism, in the initial state, the gripping mechanical fingers are open, the bag-supporting cylinder is closed, and the bag-opening clearance cylinder is extended. The connecting rod of the swing arm in the swing arm bag-loading mechanism is connected to the bag-feeding mechanism to achieve the same action. When working, the rotating shaft rotates to allow the bag-supporting plate to enter the bag opening, and then the bag-supporting cylinder opens to allow the bag-supporting plate to open the bag opening, making it easier for the bag to enter the filling port later. The gripping mechanical fingers clamp the bag, thus realizing the initial bag-clamping action. The swing arm bag-loading operation is a linkage action of the bag-feeding mechanism.

[0042] When the bags are first loaded, there are no rice bags coming out of the feeding mechanism. Therefore, the feeding seat of the feeding mechanism moves forward, driving the connecting rod, which in turn drives the swing arm of the bag-loading mechanism to swing upwards to load the bags. For example... Figure 4 As shown, after the bag-loading mechanism of the swing arm reaches the filling mechanism. (The sentence is incomplete and requires more context to translate accurately.) Figure 6As shown, in the initial state, the bag-sorting mechanical fingers are open, the bag-sorting cylinder is retracted, and the bag-clamping cylinder retracts, causing the bag-clamping rubber to open and the filling port to close. At the start of operation, the bag-clamping cylinder closes to clamp the bag, and the probe on the bag-clamping rubber detects the presence of a bag. The bag-sorting mechanical fingers then close the bag clamp. Next, the rotating shaft rotates, causing the bag-supporting plate to retract from the bag opening, and the bag-supporting clearance cylinder retracts, moving the bag-supporting plate out of the safe range of the filling port. Simultaneously, the bag-clamping mechanical fingers open to release the bag, and the bag-feeding seat retracts, causing the swing arm bag-raising mechanism to swing downwards back to its original position. The swing arm bag-raising mechanism begins a new bag clamping cycle, the filling port opens for filling, and at this time, the bag-sorting cylinder extends inwards, and both bag-sorting mechanical fingers move inwards, achieving the automatic bag opening retraction function.

[0043] During the filling process, the bag support plate under the bag moves up and down, patting the bottom of the bag. After filling, the support plate aligns with the bag-out conveyor, facilitating the transfer of rice bags. The filling nozzle closes, the bag-clamping cylinder retracts, releasing the bag from its gripper rubber, and the bag-sorting cylinder retracts, pulling the bag opening straight outwards by the bag-sorting mechanical fingers, thus completing the bag-clamping, filling, and sorting functions. The bag then awaits handover to the bag-delivering mechanism.

[0044] After filling is complete, wait for the packaging delivery organization to hand over the pallet. For example... Figure 7 In the initial state, the left and right electric cylinders retract, the left and right pneumatic finger claws open, the left and right bag-holding cylinders retract, and the piston rods of the left and right lifting cylinders extend upwards. For example... Figure 8 After packaging bag A17 is filled with materials, the electric cylinder and the bag-supporting cylinder operate simultaneously. The left and right electric cylinders move inward, the left and right pneumatic fingers clamp the bag opening, the bag-sorting mechanical fingers release, and the piston rods of the left and right lifting cylinders retract downward, disengaging the bag opening from the filling mechanism. The left and right electric cylinders then move outward, causing the left and right pneumatic fingers to pull the bag opening straight. The piston rods of the left and right bag-supporting cylinders extend, allowing the left and right support plates to hold the bag body, with the bottom of the bag positioned on the bag-supporting plate. The servo motor drives the crank-slider mechanism, pushing the bag-feeding seat forward. Figure 9 The bag-feeding seat moves horizontally forward along the slider rail, causing the pneumatic fingers and bag-supporting cylinders to move horizontally forward as well. This enables the rice bags to be conveyed to the next workstation via an outgoing conveyor. For different bag sizes, the left and right electric cylinders can adaptively adjust their positions according to the bag width; the left and right support plates and bag-supporting plates can adaptively adjust their height according to the bag height.

[0045] As the rice bags are conveyed to the outgoing conveyor, the bag-feeding mechanism drives the swing-arm bag-loading mechanism to load the bags. The swing-arm bag-loading mechanism and the bag-feeding mechanism move synchronously without causing interference. Once the rice bags reach their designated positions, all grippers on the bags release. The bag-feeding mechanism then retracts, and the swing-arm bag-loading mechanism swings downwards back to its original position. This process is repeated.

[0046] The bag-out conveyor starts working, with two conveyor belts driving the rice bags. When a rice bag leaves the photoelectric switch, the conveyor belt connected to the bag-feeding mechanism stops running, waiting for the bag-feeding mechanism to deliver more rice bags. The conveyor belt not connected to the bag-feeding mechanism continues to run, continuing to deliver rice bags out and into the subsequent sewing station.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
