Description

Technical Field

[0001] The present invention relates to the field of packaging machinery, in particular to an integrated inner and outer packaging machine. Background Art

[0002] An existing packaging method involves placing the material into an inner bag, sealing it, placing the inner bag into an outer bag, and then sealing the outer bag to complete the packaging. This composite packaging method, combining inner and outer bags, allows for the outer bag to be printed with desired graphics or other promotional content, while ensuring safety, sealing, and non-toxicity requirements for food and other materials.

[0003] The existing inner and outer bag packaging method often adopts manual filling or automatic filling. Although the method of manually stuffing the inner bag into the outer bag can ensure that the inner bag is transferred into the outer bag, the efficiency is slow and cannot meet the requirements of automated packaging. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated inner and outer packaging machine to improve packaging efficiency in response to the above problems.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is an inner and outer packaging integrated machine, which includes an inner bag packaging part and an outer bag packaging part and a transfer part between the two, wherein the inner bag packaging part is responsible for loading the material into the inner bag, and the loading part moves the packed inner bag to the outer bag packaging part, and the inner bag is loaded into the outer bag through the outer bag packaging part; the inner bag packaging part includes an inner packaging workbench, and the outer bag packaging part includes an outer packaging workbench, and both the inner and outer packaging workbench are provided with a bagging mechanism, and the bagging mechanism includes a rotary rotating along a vertical axis. A rotating ring is provided on which a clamping group for clamping the edges of both sides of the packaging bag is provided. The clamping group includes clamping jaws arranged at horizontal intervals. The distance between the clamping jaws on both sides is adjustable to adapt to operations such as filling and sealing. The inner and outer workbenches are provided with bag opening devices. The bag opening devices are responsible for opening the inner or outer bag during the material filling process or the inner bag filling process. When the inner or outer bag is opened, the distance between the clamping jaws on both sides is shortened so that the bag opening can be opened. After the filling is completed, the distance between the clamping jaws on both sides is increased to straighten the bag opening.

[0006] Furthermore, in order to reduce the driving mechanism and ensure that the clamping group can be opened and closed accurately according to its position, the rotating ring is arranged on the outside of the inner ring, and the upper end face of the inner ring is provided with a boss portion. The clamping driving mechanism for driving the clamping group to open and close rotates on the upper end face of the inner ring. Through the setting of the boss portion, the clamping group can be opened when it moves to the area of ​​the boss portion, and can be automatically retracted when it moves to the area outside the boss portion.

[0007] Furthermore, in order to cooperate with the boss part, the clamping group is now automatically opened and closed; a rotating shaft is provided on the rotating ring, and the two clamping jaws on the same clamping group are respectively provided on two adjacent rotating shafts, and the two clamping jaws on the same clamping group are connected by a reset spring; the clamping drive mechanism includes a rolling part that rotates on the upper end face of the inner ring, the rolling part is provided at one end of the toggle member, the middle part of the toggle member is rotatably provided on the mounting part, and the other end of the toggle member is in contact with one side of the clamping jaw.

[0008] Furthermore, during the packaging process, the clamp needs to fix the two side edges of the packaging bag. At the same time, in order to reduce the driving mechanism, reduce costs and maintenance difficulty, the clamp includes a fixed part and a movable part. One end of the movable part is rotatably connected to one end of the fixed part, and the other end of the movable part is rotatably connected to one end of the L-shaped pendulum. The other end of the L-shaped pendulum is rotatably connected to the movable clamping part. The fixed part is provided with a clamping spring connected to the movable part.

[0009] Furthermore, the packaging bag needs to be opened before filling, and the bag opening device includes adsorption parts arranged on the front and back sides of the packaging bag, and the adsorption parts move along the opening direction of the packaging bag.

[0010] Furthermore, during filling, in order to prevent the material from falling out of the packaging bag, the bag opening device also includes relatively arranged paddles, which move in the vertical direction. After the paddles are inserted into the packaging bag, the paddles on both sides move toward the outside of the packaging bag respectively, and the material can enter the packaging bag from between the paddles.

[0011] Furthermore, due to the possibility of missing bags and other phenomena, the inner packaging workbench and the outer packaging workbench are also provided with an empty bag rejection mechanism, and the empty bag rejection mechanism includes a rejection drive mechanism that moves in the vertical direction, and a rocker arm is provided on the piston rod of the rejection drive mechanism, and an abutment portion that contacts the rocker arm is provided at the lower end of the movable portion. The rocker arm moves, thereby opening the clamping jaws, and the packaging bags that have not completed filling fall from the clamping jaws.

[0012] Furthermore, in order to move the material to the lower end of the inner bag and avoid the material staying at the bag opening, thereby affecting subsequent sealing processes, a shaking part is provided on the inner bag workbench, and the shaking part includes a shaking drive mechanism, the piston rod of the shaking drive mechanism is connected to the moving part, and a baffle cooperating with the moving part is provided on a clamping jaw of the clamping group.

[0013] Furthermore, in order to achieve continuous production, the transfer part includes a fixed disk, a rotating disk and a pushing part. The fixed disk is provided with a discharge port. The position of the pushing part is adapted to the discharge port, and the discharge port is located on one side of the outer workbench; the rotating disk and the fixed disk are arranged in the same direction and the rotating disk rotates around its axial direction. The rotating disk is provided with a feeding port, and a feeding pipe is provided in the feeding port.

[0014] Furthermore, since the calibers of the inner bag and the outer bag are often slightly different, in order to prevent the inner bag from hitting the edge of the outer bag during filling, thereby causing poor packaging, the discharge tube includes clamping parts arranged horizontally at intervals, and the clamping parts on both sides move laterally.

[0015] The beneficial effects of the present invention are as follows: the opening and straightening of inner and outer bags and other packaging bags can be automatically completed, thereby automatically realizing the filling and sealing of materials or inner bags and improving packaging efficiency.

[0016] 1. Through the cooperation of the clamping drive mechanism and the boss part, the clamping group can be automatically opened and closed without a drive unit such as a cylinder, thereby meeting the needs of automated production while simplifying the control program and reducing the number of drive mechanisms.

[0017] 2. An empty bag rejection mechanism is provided to make the empty bags fall off the clamping group, thus improving the packaging quality.

[0018] 3. A transfer unit is provided to move the filled inner bag to the outer bag packaging unit, thereby completing the process of putting the inner bag into the outer bag, while trying to avoid the inner bag touching the edge of the outer bag, etc., reducing the occurrence of defects during packaging.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0032] Example 1, as Figure 1-4 As shown, the structure of this embodiment is: an inner and outer packaging integrated machine, which includes an inner bag packaging part 1 and an outer bag packaging part 2 and a transfer part 3 therebetween; the transfer part 3 moves the inner bag that has completed filling in the inner bag packaging part 1 to the outer bag packaging part 2 for the subsequent process of putting the inner bag into the outer bag, the inner bag packaging part 1 includes an inner packaging workbench 101, the outer bag packaging part 2 includes an outer packaging workbench 201, and both the inner packaging workbench 101 and the outer packaging workbench 201 are provided with a bagging mechanism 4.

[0033] The bagging mechanism 4 includes a rotating ring 401 rotating along a vertical axis. The rotating ring 401 is provided with a clamping group for clamping the edges of the packaging bag on both sides. The clamping group includes clamping jaws 402 arranged at horizontal intervals, and the distance between the clamping jaws 402 on both sides is adjustable.

[0034] The inner packaging workbench 101 and the outer packaging workbench 201 can be flexibly arranged on the outside of the rotating ring 401 according to needs. In this embodiment, the bag supply device 5, the coding station, the bag opening station, the filling station, the shaking station, the empty bag rejection station and the heat sealing station are sequentially arranged on the inner packaging workbench 101 in the rotation direction of the rotating ring 401 to explain the work, and the bag supply device 5, the bag opening station, the filling station, the empty bag rejection station and the heat sealing station are sequentially arranged on the outer packaging workbench 201 in the rotation direction of the rotating ring 401 to explain the work. Figure 2 On the top, the rotating ring 401 and the transfer part 3 rotate clockwise; the number of clamping groups is designed according to the number of workstations.

[0035] The specific working process is as follows: The bag feeding device 5 on the inner bag workbench 101 moves the inner bag between the two clamping jaws 402 of the clamping group. The two clamping jaws 402 then grasp the two sides of the inner bag. The clamping jaws 402 can be pneumatically operated. The clamping group then moves to the coding station, where the inner bag is coded. After coding, the clamping group moves to the bag opening station, where a vacuum suction cup or other device pulls the inner bag open. The two clamping jaws 402 in the clamping group then close the distance between them as the bag opening opens. The opened inner bag moves to the filling station, where material drops from the material processing line into the inner bag. The filling station can be equipped with a funnel or other device. After the material enters the inner bag, the clamping group drives the inner bag to the shaking station. At this shaking station, a linear drive mechanism such as a cylinder can be used to tap the inner bag, causing the inner bag to shake, ensuring that the material does not get stuck in the bag opening. Then, visual sensors and weighing sensors are used to detect whether the inner bag contains material. If it does, the inner bag passes normally when it moves to the empty bag rejection station. If it does not, the clamp 402 is opened at the empty bag rejection station, and the empty inner bag falls from the clamp 402. The inner bag is in the open state at the empty bag rejection station. After the inner bag passes the empty bag rejection station, the clamp 402 opens, straightening the bag opening and entering the heat sealing station, where it is sealed using a rice knives or other methods.

[0036] After sealing, the transfer part 3 is used to move the inner bag to the top of the filling station of the outer packaging workbench 201. The transfer part 3 can adopt a robot, etc. At this time, the bag supply device 5 on the outer bag packaging part 2 moves the outer bag to the clamping group on the outer packaging workbench 201. The outer bag passing through the bag opening station is opened and moved to the bottom of the inner bag. At this time, the inner bag enters the outer bag to complete the filling. The outer bag passes through the empty bag rejection station and the heat sealing station in turn, thereby completing the entire completion process. The bag supply device 5, the bag opening station, the heat sealing machine used in the heat sealing station, etc. used in the above embodiment can adopt mature products on the market, and their structure will not be described in detail here.

[0037] Example 2, as Figure 7-8As shown, other structures and working methods of this embodiment can refer to Example 1, but in this embodiment, the rotating ring 401 includes a top plate 408 and a rotating ring 409 spaced apart from top to bottom, the rotating ring 409 is sleeved on the outside of the inner ring 403, the top plate is located above the inner ring 403, the inner ring 403 is installed on the inner packaging workbench 101 and the outer packaging workbench 201, the rotating ring 401 rotates in coordination with the inner ring 403, the rotating ring 401 can be driven by a motor, hydraulics, etc., the upper end surface of the inner ring 403 is provided with a boss portion 4031, the area of ​​the boss portion 4031 is adapted to the positions of the bag supply device 5, the coding station and the heat sealing station.

[0038] A rotating shaft 4011 is provided on the rotating ring 401, and the opposite sides of the two jaws 402 on the same clamping group are respectively provided on two adjacent rotating shafts 4011. Among the two jaws 402 on the same clamping group, one of the jaws 402 is provided with a driving block 4028 extending toward the other jaw 402, and the driving block 4028 supports the side wall of the other jaw 402. The driving block 4028 has a non-circular structure. The two jaws 402 are connected by a reset spring 404, so that the jaws 402 can open and close synchronously.

[0039] The clamping drive mechanism includes a rolling part 405 that rotates on the upper end surface of the inner ring 403. The rolling part 405 can be a roller, etc. The rolling part 405 is arranged at one end of the toggle member 406. The toggle member 406 can be L-shaped. The middle part of the toggle member 406 is rotatably arranged on the mounting part 407. The upper end of the mounting part 407 is fixed on the top plate 408. The other end of the toggle member 406 contacts the side wall of one side of the clamp 402; the contact area between the toggle member 406 and the clamp 402 and the contact area between the drive block 4028 and the clamp 402 are both located on the inner side of the rotating ring 401.

[0040] Specific working process: When the rolling part 405 moves to the boss part 4031, the rolling part 405 is lifted, thereby driving the toggle member 406 to move toward the side of the clamping jaw 402, and then pushing one side of the clamping jaw 402 to open. At this time, due to the action of the driving block 4028, the other side of the clamping jaw 402 on the same clamping group also moves toward its outside, thereby causing the clamping group to open.

[0041] When the rolling portion 405 moves to the area of ​​the non-boss portion 4031 at the upper end of the inner ring 403, the rolling portion 405 descends, and the toggle member 406 moves toward the distal end of the clamping claw 402. Under the action of the return spring 404, the clamping assembly is closed, and the bag opening is now in an open state.

[0042] Example 3, as Figure 4-9As shown, other structures and working methods of this embodiment can refer to Example 1 or 2, but in this embodiment, the clamping jaw 402 includes a fixed part 4021 and a movable part 4022, one end of the movable part 4022 is rotatably connected to one end of the fixed part 4021, the other end of the movable part 4022 is rotatably connected to one end of the L-shaped pendulum 4023, the other end of the L-shaped pendulum 4023 is rotatably connected to the movable clamping part 4024, and a clamping spring 4025 connected to the movable part 4022 is provided on the fixed part 4021.

[0043] An empty bag rejection mechanism is also provided on the inner packaging workbench 101 and the outer packaging workbench 201. The empty bag rejection mechanism is located at the empty bag rejection station and is not located in the area where the boss portion 4031 is located. The empty bag rejection mechanism includes a rejection drive mechanism 7 that moves in the vertical direction. The rejection drive mechanism 7 can adopt a hydraulic cylinder, an electric push rod, etc. In this embodiment, a cylinder is adopted. The lower end of the rejection drive mechanism 7 is hinged to the support 11, and the support 11 is installed on the inner packaging workbench 101 and the outer packaging workbench 201. The piston rod of the rejection drive mechanism 7 is connected to the lower end of the rocker arm 8. The rocker arm 8 is L-shaped, and the middle part of the rocker arm 8 is hinged to the upper end of the support 11. The lower end of the movable part 4022 is provided with a supporting part 4026 that contacts the upper end of the rocker arm 8.

[0044] Specific working process: The two side edges of the packaging bag are fixed between the movable clamping part 4024 and the end face of the fixed part 4021. When the packaging bag that has not completed filling moves to the empty bag rejection station, the piston rod of the rejection drive mechanism 7 rises, causing the rocker arm 8 to push the abutment part 4026 to move toward the outside of the rotating ring 401, thereby opening the movable clamping part 4024 and releasing the packaging bag.

[0045] Example 4, as Figure 4-6 As shown, other structures and working methods of this embodiment can refer to Example 1 or 2, but in this embodiment, a shaking part is provided on the inner package workbench 101, and the shaking part is located at the shaking station. The shaking part includes a shaking drive mechanism 9, and the shaking drive mechanism 9 can adopt a hydraulic cylinder, an electric push rod, etc., and a cylinder is adopted in this embodiment; the shaking drive mechanism 9 is installed on the inner ring 403 and is not located in the area of ​​the boss part 4031. The piston rod of the shaking drive mechanism 9 is connected to the moving part 10, and a baffle 4027 cooperating with the moving part 10 is provided on a clamping jaw 402 of the clamping group, and the baffle 4027 forms an angle with the rotation path of the rotating ring 401 on the vertical projection plane.

[0046] Specific working process: The shaking drive mechanism 9 pushes the moving part 10 to move toward the inside of the clamping group. During the movement of the moving part 10, the distance between the baffle 4027 and the tangent of the rotation path of the rotating ring 401 is shortened, so that the two clamping jaws 402 are close to each other. As the moving part 10 moves back and forth, the inner bag shakes.

[0047] Example 5, as Figure 1-2 As shown, other structures and working methods of this embodiment can refer to other embodiments, but in this embodiment, the bag opening device 6 includes an adsorption portion 601 arranged on the front and back sides of the packaging bag, and the adsorption portion 601 moves along the opening direction of the packaging bag. The adsorption portion 601 is located in the area where the boss portion 4031 is located.

[0048] The bag opening device 6 further includes paddles 602 arranged opposite to each other. The paddles 602 move in a vertical direction. After the paddles 602 are inserted into the packaging bag, the paddles 602 on both sides move toward the outside of the packaging bag respectively.

[0049] Specific working process: in the rotation direction of the rotating ring 401, the paddle 602 is located behind the adsorption part 601, and the paddle 602 is located at the filling station. The adsorption part 601 can adopt a vacuum suction cup, and the adsorption part 601 and the paddle 602 can be pushed by a hydraulic cylinder, an electric push rod, etc. In this embodiment, a cylinder is used for pushing. The packaging bag is first moved between the adsorption parts 601 on both sides, and then the adsorption part 601 moves toward the packaging bag to adsorb the front and back sides of the packaging bag. Then, the adsorption parts 601 are pushed away from each other by the cylinder until they are separated from the packaging bag, thereby opening the packaging bag.

[0050] The packaging bag is then moved to the bottom of the paddle 602. At this time, the paddles 602 on both sides are close to each other, and then the paddle 602 moves downward to be inserted into the packaging bag. Then the paddles 602 on both sides move away from each other to open the packaging bag to facilitate filling of the material. After filling is completed, the paddle 602 rises and resets.

[0051] Example 6, as Figure 10-11 As shown, other structures and working methods of this embodiment may refer to other embodiments, but in this embodiment, the transfer unit 3 includes, from bottom to top, a fixed disk 301, a rotating disk 302, and a pushing unit 303. The fixed disk 301 is provided with a discharge port 304, the position of the pushing unit 303 being adapted to the discharge port 304, and the discharge port 304 is located at the filling station in the outer packaging workbench 201; the rotating disk 302 is arranged in the same direction as the fixed disk 301 and the rotating disk 302 is driven by a motor or the like to rotate around its axis. The rotating disk 302 is provided with a feeding port, which is arranged in a circular array around the axis of the rotating disk 302. A feeding pipe 305 is provided in the feeding port. The feeding pipe 305 includes horizontally spaced clamping portions 306, which are arranged on both sides along the inner wall of the feeding port for transverse movement, and the lower end of the clamping portion 306 faces the fixed disk 301.

[0052] During specific operation, the sealed inner bag is moved to the discharge tube 305 close to the inner packaging workbench 101 by a robot or by directly dropping. The working mode of the robot can be to use a rotating cylinder to drive the pneumatic fingers to move the inner bag to the designated place. The pneumatic fingers are responsible for clamping the packaged inner bag and moving it to the outer bag packaging part 2. At this time, the inner cavity of the discharge tube 305 is slightly larger than the inner bag, so that the packaged inner bag can fall into the discharge tube 305. The fixed plate 301 supports the lower end of the inner bag, so that the inner bag rotates with the rotating plate 302.

[0053] During the rotation of the rotating disk 302 , the cylinder provided at the lower end of the rotating disk 302 is used to push the clamping parts 306 on both sides to move toward each other, thereby tightening the discharge pipe 305 and further shrinking the inner bag.

[0054] When the discharge tube 305 rotates to the discharge port 304, the outer bag is located below the discharge port 304 in an open manner, and the pushing part 303 moves toward the fixed disk 301 under the push of the cylinder, etc. to push the inner bag into the outer bag. After the inner bag is pushed out of the discharge tube 305, the discharge tube 305 reopens and rotates again with the rotating disk 302 to continue the next packaging.
