Description

Technical Field

[0001] The present invention relates to the technical field of food and drug packaging machinery and equipment, and particularly relates to a film cutting and sealing machine and a film cutting and sealing method. Background Art

[0002] The existing film cutting and sealing machine includes a film cutting and releasing device and a bottle conveying mechanism. The film cutting and releasing device is arranged at the upper film working position of the bottle conveying mechanism. The film cutting and releasing device generally includes a staggered film cutting mechanism and a film sucking and transferring mechanism. The film sucking and transferring mechanism transports the film pieces cut by the staggered film cutting mechanism to the bottles at the upper film working position. The existing staggered film cutting mechanism generally cuts the film in rows, and the film pieces in each row are flat and aligned, resulting in low utilization rate of the film and large waste. Secondly, the existing film sucking and transferring mechanism generally has only two degrees of freedom in the front-back and up-down directions, and requires high installation accuracy for the relative positions of the staggered film cutting mechanism and the film sucking and transferring mechanism. For example, after the staggered film cutting mechanism and the film sucking and transferring mechanism are installed, if the relative position error is large, manual reinstallation is required to eliminate the installation error, which is time-consuming, laborious and difficult. Moreover, the film releasing station and the film sealing station of the film cutting and sealing machine are set at the same place, and it is necessary to wait for the parts at the film releasing position to move away before sealing the film, resulting in low working efficiency. When the film is transferred from the film releasing station to the film sealing station, the film is easy to fall or shift. Summary of the Invention

The supporting surface includes a horizontal section and a gradually rising pushing section. The top edges of the horizontal section and the pushing section are connected and extend below the film placing station and the film sealing station. On one side of the bottle conveying mechanism, there is a guiding surface. The guiding surface includes a straight section and a pushing section that gradually approaches the bottle conveying mechanism. The side of the straight section and the pushing section close to the bottle conveying mechanism are connected and extend to the side of the film placing station and the film sealing station.

The film sucking nozzle is arranged on the film taking group, and the film taking group is installed on the frame through the front-back moving seat, the up-down moving seat and the left-right moving seat.

[0010] The left-right moving seat is slidably arranged on the frame. The up-down moving seat is slidably arranged on the left-right moving seat. The front-back moving seat is slidably arranged on the up-down moving seat.

[0011] The first driving mechanism includes a front-back telescopic driving member. The front-back telescopic driving member is arranged on the up-down moving seat, and the front-back moving seat is connected with the telescopic end of the front-back telescopic driving member. The second driving mechanism includes an up-down telescopic driving member. The up-down telescopic driving member is arranged on the left-right moving seat, and the up-down moving seat is connected with the telescopic end of the up-down telescopic driving member. The third driving mechanism includes a left-right telescopic driving member. The left-right telescopic driving member is arranged on the frame, and the left-right moving seat is connected with the telescopic end of the left-right telescopic driving member.

[0012] The misaligned film cutting mechanism includes a film cutting frame and a new film roll dispenser, a misaligned film cutting die and a waste film roll collector arranged on the film cutting frame. The misaligned film cutting die is arranged corresponding to each film sucking nozzle.

[0013] On the film sealing station, there is a film sealing mechanism. The film sealing mechanism includes a film sealing frame, a film sealing seat and a heat sealing head. The film sealing seat is arranged to be lifted and lowered on the film sealing frame. The film sealing frame is provided with a lifting driving mechanism for driving the film sealing seat to lift and lower. The heat sealing head is arranged to be liftable on the film sealing seat. A buffer elastic member is arranged between the film sealing seat and the heat sealing head.

[0014] On the carrier, there is a guiding mechanism for the lifting and guiding of the film sucking nozzle and the heat sealing head. The bottle conveying mechanism is a circulating conveying mechanism.

[0015] A film cutting and sealing method is carried out by using the above-mentioned film cutting and sealing machine, and it includes the following steps:

[0016] S1. Bottle placing: The bottle body is conveyed to the carrier on the bottle body conveying mechanism;

[0017] S2. Film placing: The film is cut by the offset film cutting mechanism. When the carrier transports the bottle body to the film placing station, the film picking suction nozzle picks up the film and places it above the bottle cap under the guidance of the film positioning member;

The specific film conveying process is completed by the film picking suction nozzle. The film picking suction nozzle can move forward and backward, up and down, and left and right relative to the offset film cutting mechanism, and has three degrees of freedom. Thus, the installation error of the relative positions of the offset film cutting mechanism and the film suction and transfer mechanism can be compensated by the movement of the film picking suction nozzle itself, thereby reducing the installation requirements for the relative positions of the offset film cutting mechanism and the film suction and transfer mechanism. Moreover, the film placing station and the film sealing station are separately arranged, and the work of the two stations can be carried out simultaneously, improving the work efficiency. Also, when the film is transferred from the film placing station to the film sealing station, under the limiting action of the film positioning member, it is not easy to fall or shift. This film cutting and sealing machine is easy to install, does not require time-consuming and laborious manual adjustment later, has high work efficiency, and avoids the film from falling or shifting during the transfer process.

[0021] In the film cutting and sealing method of the present invention, when placing the film, the film is accurately placed above the bottle cap under the guiding action of the film positioning member, preventing the film from being misaligned with the bottle body, and the film placing effect is good. When the film is transferred from the film placing station to the film sealing station, under the limiting action of the film positioning member, it is not easy to fall or shift. Moreover, the film placing station and the film sealing station are separately arranged, and the work of the two stations can be carried out simultaneously, improving the work efficiency. This film cutting and sealing method can improve the work efficiency, has a good film placing effect, and can avoid the film from falling or shifting during the transfer process.

[0031] The following will further describe the present invention in detail with reference to the accompanying drawings of the specification and specific embodiments.

[0032] Embodiment 1:

[0033] Figures 1 to 7An embodiment of the film cutting and sealing machine of the present invention is shown. The film cutting and sealing machine includes a misaligned film cutting mechanism 1, a film sucking and transporting mechanism 2, and a bottle transporting mechanism 3. The bottle transporting mechanism 3 is sequentially provided with a film placing station 4 and a film sealing station 5 along the transporting direction. The film sucking and transporting mechanism 2 for transporting the film of the misaligned film cutting mechanism 1 to the carrier 31 at the film placing station 4 is provided at the film placing station 4. The film sucking and transporting mechanism 2 includes a frame 21 and a plurality of film picking suction nozzles 23 provided on the frame 21 and capable of moving back and forth, up and down, and left and right relative to the misaligned film cutting mechanism 1. The bottle transporting mechanism 3 includes a carrier 31 for transporting the bottle and the film from the film placing station 4 to the film sealing station 5. A film positioning member 311 for positioning the film is provided on the carrier 31.

[0034] The bottle is placed on the carrier 31. The carrier 31 moves along the transporting direction of the bottle transporting mechanism 3 and sequentially passes through the film placing station 4 and the film sealing station 5. The bottle is film placed at the film placing station 4 and film sealed at the film sealing station 5. The film sucking and transporting mechanism 2 is used to transport the film of the misaligned film cutting mechanism 1 to the carrier 31 at the film placing station 4. The specific film transporting process is completed by the film picking suction nozzle 23. The film picking suction nozzle 23 can move back and forth, up and down, and left and right relative to the misaligned film cutting mechanism 1 and has three degrees of freedom. Thus, the installation error of the relative positions of the misaligned film cutting mechanism 1 and the film sucking and transporting mechanism 2 can be compensated by the movement of the film picking suction nozzle 23 itself, thereby reducing the installation requirements for the relative positions of the misaligned film cutting mechanism 1 and the film sucking and transporting mechanism 2. Moreover, the film placing station 4 and the film sealing station 5 are separately arranged, and the work of the two stations can be carried out simultaneously, improving the work efficiency. Also, when the film is transferred from the film placing station 4 to the film sealing station 5, it is not likely to fall or shift under the limiting action of the film positioning member 311. This film cutting and sealing machine is easy to install, does not require time-consuming and laborious manual adjustment later, has high work efficiency, and avoids the film from falling or shifting during the transfer process.

[0035] In this embodiment, a lateral guiding assembly 314 and a vertical guiding member 312 are further provided on the carrier 31. The lateral guiding assembly 314 is connected with a lateral rolling member 315. One end of the vertical guiding member 312 facing the film positioning member 311 is provided with a bottle holder 7, and the other end is provided with a jacking and pushing portion 313.

[0036] As Figure 4As shown in the figure, before the film placing station 4, under the driving force of an external force, the lateral rolling member 315 causes the lateral guiding assembly 314 to move laterally, so that the film positioning member 311 moves laterally above the bottle body on the bottle holder 7, realizing the alignment of the film positioning member 311 and the bottle body. The structure is simple and the alignment is convenient. The film positioning member 311 moves to above the bottle body on the bottle holder 7, so that the film positioning member 311 is pre-aligned with the bottle cap. Moreover, the lifting and pushing part 313 can make the vertical guiding member 312 rise vertically, so that the bottle body on the bottle holder 7 approaches the upper film positioning member 311 to an appropriate position for film placing and subsequent film sealing, making the alignment accuracy of the film at the film placing station 4 and the film sealing station 5 high and avoiding the occurrence of misalignment phenomena.

[0037] In this embodiment, a support surface 8 for supporting the lifting and pushing part 313 is provided below the bottle body conveying mechanism 3. The support surface 8 includes a horizontal section 82 and a gradually rising pushing section 81. The top edges of the horizontal section 82 and the pushing section 81 are connected and extend below the film placing station 4 and the film sealing station 5. A guiding surface 9 is provided on one side of the bottle body conveying mechanism 3. The guiding surface 9 includes a straight section 92 and a pushing section 91 that gradually approaches the bottle body conveying mechanism 3. The side of the straight section 92 and the pushing section 91 close to the bottle body conveying mechanism 3 are connected and extend to the side of the film placing station 4 and the film sealing station 5.

[0038] Before the carrier 31 enters the film placing station 4, it passes through the pushing section 91. The lateral rolling member 315 on the carrier 31 moves along the pushing section 91 towards the straight section 92. At the same time, the lateral guiding assembly 314 moves laterally, so that the film positioning member 311 moves above the bottle body on the bottle holder 7. When the lateral rolling member 315 on the carrier 31 abuts against the straight section 92, the film positioning member 311 remains above the bottle body on the bottle holder 7. Before the carrier 31 enters the film placing station 4, the carrier 31 passes through the pushing section 81. The lifting and pushing part 313 on the carrier 31 moves along the pushing section 81 towards the horizontal section 82. At the same time, the lifting and pushing part 313 moves upward, so that the bottle body on the bottle holder 7 approaches the upper film positioning member 311 to an appropriate position. When the lifting and pushing part 313 abuts against the horizontal section 82, the bottle body on the bottle holder 7 remains at an appropriate position from the film positioning member 311 for subsequent film placing and film sealing, making the alignment accuracy of the film at the film placing station 4 and the film sealing station 5 high and avoiding the occurrence of misalignment phenomena.

[0039] In this embodiment, as Figure 5 and Figure 6As shown, the film suction and transfer mechanism 2 further includes a front-back moving seat 24, an up-down moving seat 25, a left-right moving seat 26, a first driving mechanism 27 for driving the front-back moving seat 24 to move back and forth, a second driving mechanism 28 for driving the up-down moving seat 25 to move up and down, and a third driving mechanism 29 for driving the left-right moving seat 26. The film suction nozzle 23 is arranged on the film picking group 22, and the film picking group 22 is installed on the frame 21 through the front-back moving seat 24, the up-down moving seat 25, and the left-right moving seat 26. The film suction nozzle 23 moves with the front-back moving seat 24, the up-down moving seat 25, and the left-right moving seat 26, thus having degrees of freedom in three directions: front-back, up-down, and left-right. Specifically, the left-right moving seat 26 is slidably arranged on the frame 21, the up-down moving seat 25 is slidably arranged on the left-right moving seat 26, and the front-back moving seat 24 is slidably arranged on the up-down moving seat 25.

[0040] In this embodiment, the first driving mechanism 27 includes a front-back telescopic driving member. The front-back telescopic driving member is arranged on the up-down moving seat 25, and the front-back moving seat 24 is connected to the telescopic end of the front-back telescopic driving member; the second driving mechanism 28 includes an up-down telescopic driving member. The up-down telescopic driving member is arranged on the left-right moving seat 26, and the up-down moving seat 25 is connected to the telescopic end of the up-down telescopic driving member; the third driving mechanism 29 includes a left-right telescopic driving member. The left-right telescopic driving member is arranged on the frame 21, and the left-right moving seat 26 is connected to the telescopic end of the left-right telescopic driving member.

[0041] In this embodiment, as Figure 5 shown, the offset film cutting mechanism 1 includes a film cutting frame 11, a new film reel dispenser 12, an offset film cutting die 13, and a waste film reel collector 14 arranged on the film cutting frame 11. The offset film cutting die 13 is arranged corresponding to each film suction nozzle 23. The offset film cutting die 13 is used for offset film cutting, so that the films in adjacent rows are offset, thereby improving the utilization rate of the film. The film suction nozzle 23 sucks the film cut by the offset film cutting die 13 to the film placing station 4.

[0042] In this embodiment, as Figure 7 shown, a film sealing mechanism 6 is arranged at the film sealing station 5. The film sealing mechanism 6 includes a film sealing frame 61, a film sealing seat 62, and a heat sealing head 63. The film sealing seat 62 is arranged to be lifted and lowered on the film sealing frame 61. An elevating driving mechanism 64 for driving the film sealing seat 62 to lift and lower is arranged on the film sealing frame 61. The heat sealing head 63 is arranged to be liftable on the film sealing seat 62. A buffer elastic member 65 is arranged between the film sealing seat 62 and the heat sealing head 63. During heat sealing, the carrier 31 transports the film to the lower part of the heat sealing head 63. The elevating driving mechanism 64 drives the film sealing seat 62 to descend, and the film is pressed down onto the lower bottle body through the heat sealing head 63. Moreover, under the heating action of the heat sealing head 63, the film is sealed on the top of the bottle body. Due to the elastic buffering effect of the buffer elastic member 65, the heat sealing head 63 and the bottle body are prevented from colliding violently.

[0043] In this embodiment, a guiding mechanism for lifting and guiding the film-taking suction nozzle 23 and the heat-sealing head 63 is provided on the carrier 31, and the bottle conveying mechanism 3 is a circulating conveying mechanism. Under the action of the guiding mechanism, the film-taking suction nozzle 23 can accurately place the film on the film positioning member 311, and moreover, the heat-sealing head 63 can be prevented from being misaligned with the film below during heat sealing. The film placement and sealing effects can be improved.

[0044] Embodiment 2:

[0045] A film cutting and sealing method is carried out by using the above film cutting and sealing machine, and it includes the following steps:

[0046] S1. Placing the bottle: The bottle is conveyed onto the carrier 31 on the bottle conveying mechanism 3;

[0047] S2. Placing the film: The misaligned film cutting mechanism 1 cuts the film. When the carrier 31 transports the bottle to the film placement station 4, the film-taking suction nozzle 23 takes the film and places it above the bottle cap under the guidance of the film positioning member 311;

[0048] S3. Heat sealing: The carrier 31 transports the bottle and the film to the heat-sealing station 5 for heat sealing. At the same time, S1 to S3 are carried out until all products are heat-sealed.

[0049] When placing the film, the film is accurately placed above the bottle cap under the guiding action of the film positioning member 311, preventing the film from being misaligned with the bottle body, and the film placement effect is good. When the film is transferred from the film placement station 4 to the heat-sealing station 5, it is not easy to fall or shift under the limiting action of the film positioning member 311. Moreover, the film placement station 4 and the heat-sealing station 5 are separately arranged, and the operations of the two stations can be carried out simultaneously, improving the work efficiency. This film cutting and sealing method can improve the work efficiency, have a good film placement effect, and can prevent the film from falling or shifting during the transfer process.

[0050] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
