Description

Technical Field

[0001] The present invention relates to a material packaging machine, in particular to a packaging and boxing device and a packaging method thereof on an automated production line for laminated filter element monomers. Background Art

[0002] High-efficiency air filters mainly include two main structures: a filter element and a box frame. As the most important structure for filtration, the filter element is generally made of ultra-fine chemical fibers and glass fiber materials; while the box frame structure mainly serves to package the filter element, making the filter element of the high-efficiency air filter form a box-shaped or box-like integral structure.

[0003] The filtration principle of high-efficiency air filters is to intercept the fine dust contained in the air passing through the filter element through the flocculent structure formed microscopically by the filter element material; in order to increase the windward area of the filter element, the filter element generally adopts a multi-layer structure, that is, multiple filter single sheets are stacked to form a filter element monomer, and folds are formed between adjacent two filter single sheets, thereby increasing the windward area. After stacking multiple filter single sheets, they are installed in a housing to form a filter element monomer; among them, the more the number of filter single sheets in the filter element monomer, the better the filtration effect. For example, most household fresh air conditioners use three filter single sheets stacked to form a filter element monomer, while in the on-vehicle air filter element of high-end new energy vehicles, generally four filter single sheets are stacked to form a filter element monomer.

[0004] On the production line of high-efficiency air filters, a predetermined number of filter single sheets need to be vertically and neatly loaded into the box frame from the side of the box frame for packaging, to prevent the multiple filter single sheets in the filter element monomer from scattering and separating. However, in the actual production environment, the filter single sheets are produced one by one; currently on the production line, each filter single sheet is turned to the vertical position by a flipping workbench and then sequentially loaded into the box frame. On the one hand, the rate of loading one by one does not match the production rate of the filter single sheets (the loading rate is lower than the production rate), and the production rate is forced to be slowed down; on the other hand, during the loading process, since the position of the flipping workbench is unchanged, therefore, it is necessary to adapt the box frame moving system to adjust the position of the box frame according to the sequential vertical stacking process of the filter single sheets, and during the vertical stacking process, a manipulator needs to always press the filter single sheet at the end of the stack; when the next filter single sheet is turned to the vertical state, the pressing manipulator is removed; after the pressing manipulator is removed, it often occurs that the multiple filter single sheets that were originally vertically and neatly stacked become unstable and loose again, interfering with the insertion of the next filter single sheet.

[0005] In addition, in order to keep the pressing manipulator always in a non-relaxed state, at least two sets of mechanical stop arms need to be matched to complete the vertical and neat stacking function. Among them, the front mechanical arm presses the multiple pre-stacked filter single pieces, and the rear mechanical arm is used to push the current filter single piece to be stacked onto the stacked multiple filter pieces; and after the current filter single piece is stacked, it is necessary to switch to the rear mechanical arm to keep the multiple filter pieces pressed, while the front mechanical arm switches to pushing the next filter single piece; the two mechanical arms alternate and operate, and interference problems often occur.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0042] Please refer to Figures 1 to 21 , as an embodiment of the present invention, the packaging and boxing device on the automated production line of the laminated filter monomer finished product includes a frame 1 and a bin body 4 horizontally installed on the frame 1; A conveying system is arranged on the bin body 4 along its length direction for conveying the filter single-piece finished products from the starting end of the bin body 4 to the other end one by one; A stacking mechanism is arranged at the conveying end of the conveying system. The stacking mechanism is installed on the bin body 4 and is matched with a turning mechanism; When the number of stacked filter single pieces on the stacking mechanism reaches a predetermined number (that is, reaches a predetermined thickness), the turning mechanism drives the stacking mechanism and the multiple stacked filter single pieces on the stacking mechanism to turn 90°, so that the predetermined number of filter single-piece finished products are vertically loaded into the monomer frame.

[0043] In this embodiment, in the present invention, by adopting a matching method to realize the mutual cooperation between the stacking mechanism and the turning mechanism, the stacking and turning actions are alternated, and the actions are strictly executed in sequence, avoiding the problem that the stacking action and the turning action interfere with each other due to action lag or cooperation signal conduction delay between the two functional structures.

[0044] As a further solution of the present invention, the turning mechanism includes a rotating part 7 rotatably arranged in the bin body 4 and a follow-up shaft sleeve 13 movably arranged in the bin body 4; The follow-up shaft sleeve 13 is slidably matched with a clamping sleeve 9, and the clamping sleeve 9 is elastically sleeved outside a fixed shaft 10. The fixed shaft 10 is installed in the bin body 4, and the follow-up shaft sleeve 13 is rotatably connected to the fixed shaft 10 through a bearing; A clamping post 8 is installed on the outside of the clamping sleeve 9 perpendicular to its axis direction. The clamping post 8 is matched with a rotating clamping tooth 701 formed on the rotating part 7. One side of the rotating clamping tooth 701 is a helical surface and the other side is a flat surface; When the rotating part 7 and the rotating clamping tooth 701 rotate until the flat surface abuts against the clamping post 8, the flat surface of the rotating clamping tooth 701 can drive the clamping post 8 and the clamping sleeve 9 to rotate, and elastic potential energy is stored during the rotation of the clamping sleeve 9; and when the flat surface of the rotating clamping tooth 701 passes over the clamping post 8, the clamping sleeve 9 and the clamping post 8 are driven to reverse and reset by releasing the elastic potential energy.

[0045] In this embodiment, in combination with the attachedFigure 16 As can be seen from the rotation direction of the rotating member 7 shown in [reference], the rotating engaging teeth 701 do not always cooperate with the engaging post 8. In the initial state, the engaging post 8 is located at the tooth root on one side of the helical surface; during most of the rotation of the rotating member 7, the rotating engaging teeth 701 do not cooperate with the engaging post 8; in this way, the rotational movement of the rotating member 7 in the previous cycle will not drive the sleeve 9 to perform any action. Only when the flat surface of the rotating engaging teeth 701 driven by the rotating member 7 rotates to contact the engaging post 8, will the engaging post 8 be driven to move.

[0046] As a further solution of the present invention, a helical fitting groove 901 is formed on the inner wall of the sleeve 9, an engaging hole 1001 is provided on the fixed shaft 10, a roller 11 is fitted in the engaging hole 1001, and the roller 11 is in rolling cooperation with the fitting groove 901; A step is further formed on the fixed shaft 10, a first compression spring 12 is sleeved on the fixed shaft 10, one end of the first compression spring 12 abuts against one end of the sleeve 9, and the other end of the first compression spring 12 abuts against the step; Wherein, the arc length occupied by the rotating engaging teeth 701 on the circumference of the rotating member 7 is 1 / 6 of the circumference, and when the engaging post 8 is separated from the flat surface of the rotating engaging teeth 701, the roller 11 rolls from one end of the fitting groove 901 to the other end.

[0047] For better visualization and explanation, the examples given in the attached drawings of the specification of the present invention are used as illustrations; the arc degree occupied by the rotating engaging teeth 701 on the circumference of the rotating member 7 given in the attached drawings of the specification is 60° (that is, the arc length occupied by the rotating engaging teeth 701 on the circumference of the rotating member 7 is 1 / 6 of the circumference), and the height difference between the tooth tip and the tooth root in the axial direction is h; and the length difference in the axial direction from one end to the other end of the fitting groove 901 is also h.

[0048] Wherein, the rotating member 7 rotates once every 60°, that is, the rotating member 7 performs an intermittent rotation behavior, stops every 60° of rotation, and after a predetermined time interval, rotates 60° again and stops again, and so on in a cycle.

[0049] Combined with the attached Figure 21 It can be seen that after the rotating member 7 and the rotating engaging teeth 701 rotate from the current position to the flat surface contacting the engaging post 8, the continuously rotating rotating engaging teeth 701 cooperate with the engaging post 8 by means of the flat surface on one side thereof, and drive the engaging post 8 and the sleeve 9 to rotate; during the rotation of the sleeve 9, due to the cooperation of the roller 11, the fitting groove 901 and the engaging hole 1001, the sleeve 9 rotates while moving along the helical direction of the fitting groove 901 and continuously compresses the first compression spring 12. Therefore, the sleeve 9 and the engaging post 8 perform a helical movement during this process. Therefore, compared with the flat surface, the engaging post 8 moves from the tooth root to the tooth top; During the process that the flat surface on one side of the rotating camming tooth 701 contacts the clamping post 8 at the tooth root and moves to the flat surface contacting the clamping post 8 at the tooth top, the rotating camming tooth 701 rotates by an angle of 60°, and the roller 11 also rolls from one end of the slot 901 to the other end; the rotating camming tooth 701 then stops, and at this time the clamping post 8 stays at the tooth top of the rotating camming tooth 701; after a predetermined time interval, the rotating camming tooth 701 rotates again. At this time, the clamping post 8 has passed over the tooth top and moves back to its original position along the spiral surface under the elastic force of the first compression spring 12, driving the clamping sleeve 9 to reverse and return to its original position; at the same time, the roller 11 also returns to the initial end of the slot 901.

[0050] As a further solution of the present invention, the rotating member 7 is installed on the main shaft 6, the main shaft 6 is rotatably arranged in the housing 4, and a stepper motor 5 is installed on one side outside the housing 4, and the output shaft of the stepper motor 5 is connected to the main shaft 6.

[0051] In this embodiment, the output shaft of the stepper motor 5 controls the main shaft 6 to rotate 60° each time, thereby driving the rotating member 7 to rotate once every 60°; it is realized that the rotating member 7 stops every 60° rotation, and after a predetermined time interval, it rotates 60° again; in this way, it circulates and steps forward by 60° in one direction each time.

[0052] As a further solution of the present invention, a keyway 1301 is axially formed on the inner wall of the follower rotating shaft sleeve 13, and a flat key 902 for sliding cooperation with the keyway 1301 is axially installed on the outer wall of the clamping sleeve 9; A large gear 14 is installed outside the follower rotating shaft sleeve 13, the large gear 14 meshes with a small gear 15, and the small gear 15 is installed on the turning shaft 16; the turning shaft 16 is rotatably arranged in the housing 4, and the stacking mechanism is connected to the turning shaft 16.

[0053] In this embodiment, due to the sliding cooperation between the keyway 1301 and the flat key 902, when the clamping sleeve 9 makes a spiral movement, it can only drive the follower rotating shaft sleeve 13 rotatably installed on the fixed shaft 10 through a bearing to rotate, thereby driving the large gear 14 to rotate, and the rotation of the large gear 14 can drive the small gear 15 to rotate; among them, during the process that the roller 11 spirally moves from one end of the slot 901 to the other end, the large gear 14 drives the small gear 15 to rotate 90°.

[0054] As a further solution of the present invention, the stacking mechanism includes a bracket 17, and one end of the bracket 17 is fixedly connected to the turning shaft 16; A bearing frame 26 is arranged in parallel on the bracket 17, and a guardrail is integrally arranged on one side of the bracket 17 close to the turning shaft 16; The conveying system includes a conveyor belt 2 , one end of the conveyor belt 2 is connected to the carrier frame 26 via a connecting plate 3 , and the connecting plate 3 is installed in the warehouse body 4 via a transverse axis.

[0055] In this embodiment, the filter sheets intermittently transported by the conveyor belt 2 in the conveying system fall one by one onto the carrier 26 through the connecting plate 3; after the filter sheets on the carrier 26 are stacked to a predetermined number (i.e., a predetermined thickness), the bracket 17 is driven to flip through the flip shaft 16, and finally the carrier 26 and the multiple filter sheets stacked thereon are flipped 90°, changing from horizontal stacking to vertical stacking.

[0056] The guardrail can ensure that when multiple filter sheets are turned over, the edges of each sheet always fit the guardrail, thereby ensuring that the edges are neat.

[0057] As a further solution of the present invention, a side beam 27 is installed on one side of the warehouse body 4, and two groups of limit columns 28 are arranged on the side beam 27, and the two groups of limit columns 28 are arranged along the plumb direction; A manipulator 29 is provided on the other side of the warehouse body 4; When the carrier 26 and the multiple filter sheets stacked thereon are turned over by 90°, the multiple filter sheets are clamped by the carrier 26 and the limiting pillars 28 .

[0058] In this embodiment, because when the support frame 26 and the multiple filter sheets stacked thereon are flipped 90°, one side of the stacked whole formed by the multiple filter sheets is limited by the support frame 26, and the other side is limited by two groups of limiting columns 28, so there is no gap between the multiple filter sheets; and at this time, the manipulator 29 is located on one side of the vertically stacked whole and is facing the center of the whole; the manipulator 29 is opened and continuously approaches the stacked whole to clamp it, and the stacked whole is clamped and sent to the outside of the warehouse body 4, and finally the multiple neatly stacked stacked whole is vertically loaded into the box frame structure to complete the packaging and boxing work.

[0059] As a further solution of the present invention, a sliding hole is provided on the bracket 17, and the sliding hole is slidably matched with a sliding rod 2601 fixedly provided on the carrier 26; The stacking mechanism also includes a compensation frame 22 that can be raised and lowered in the warehouse body 4, and the compensation frame 22 cooperates with the supporting frame 26; the compensation frame 22 is connected to the main shaft 6 through a sedimentation structure, and the sedimentation structure drives the supporting frame 26 to move downward intermittently when the main shaft 6 rotates and the ferrule 9 is stationary, and its single downward movement height is equal to the thickness of the filter sheet.

[0060] In this embodiment, taking the example shown in the illustrations of the specification, during the process of the main shaft 6 driving the rotating member 7 and the rotating cogs 701 to rotate the first 60°, the sleeve 9 remains stationary; meanwhile, the carrier 26 is located at the highest position and remains stationary. At this time, the height difference between the upper surface of the carrier 26 and the lowest end of the ramp surface of the connecting plate 3 is the thickness of a single filter sheet; the first single filter sheet sent by the conveyor belt 2 falls onto the carrier 26 through the connecting plate 3; During the process of the main shaft 6 driving the rotating member 7 and the rotating cogs 701 to rotate the second 60°, the sleeve 9 still remains stationary; meanwhile, the main shaft 6 drives the compensating frame 22 to move down by the thickness of a single filter sheet through the settlement structure. After the compensating frame 22 moves down, the carrier 26 also moves down by the thickness of a single filter sheet under the action of gravity, so as to keep the height of the first single filter sheet falling onto the carrier 26 equal to the initial highest position of the carrier 26, avoiding that the second single filter sheet cannot be stacked on the first single filter sheet due to too small a height difference; or that the second single filter sheet generates excessive friction due to too large a path during the process of being stacked on the first single filter sheet, resulting in position deviation, or that the stacking is insufficient due to the reason of frictional resistance, and there is a large gap between adjacent single filter sheets, thereby affecting the normal stacking of the next single filter sheet; During the process of the main shaft 6 driving the rotating member 7 and the rotating cogs 701 to rotate the third 60°, the sleeve 9 still remains stationary; meanwhile, the main shaft 6 drives the compensating frame 22 to move down by the thickness of a single filter sheet through the settlement structure, and the carrier 26 also moves down by the thickness of a single filter sheet, so as to keep the height of the second single filter sheet falling onto the carrier 26 equal to the initial highest position of the carrier 26, avoiding that the third single filter sheet cannot be stacked on the second single filter sheet; or that the third single filter sheet generates deviation during the process of being stacked on the second single filter sheet.

[0061] During the process of the main shaft 6 driving the rotating member 7 and the rotating cogs 701 to rotate the fourth 60°, the sleeve 9 still remains stationary; meanwhile, the main shaft 6 drives the compensating frame 22 to move down by the thickness of a single filter sheet through the settlement structure, and the carrier 26 also moves down by the thickness of a single filter sheet, so as to ensure that the fourth single filter sheet can be successfully stacked on the third single filter sheet.

[0062] At the beginning of the main shaft 6 driving the rotating member 7 and the rotating sprocket 701 to rotate the fifth 60°, the conveying system stops conveying new single filter pieces through the operation parameter settings via the connecting plate 3 (intermittent program shutdown); during the process of the rotating sprocket 701 rotating the fifth 60°, the flat surface on one side of the rotating sprocket 701 cooperates with the clamping post 8, driving the clamping post 8, the clamping sleeve 9, and the flat key 902 to perform a spiral motion along the groove 901 under the action of the roller 11, and the clamping post 8 moves from the tooth root on the flat surface side to the tooth top; and, during this process, the clamping sleeve 9 continuously approaches the step on the fixed shaft 10, further compressing the first compression spring 12; at the same time, the flat key 902 drives the follower rotating shaft sleeve 13 to only perform a rotational motion through cooperation with the keyway 1301; the follower rotating shaft sleeve 13 drives the small gear 15 to rotate through the large gear 14, ultimately driving the turning shaft 16, the bracket 17, and the bearing frame 26 to rotate 90°; at the same time, the main shaft 6 drives the compensation frame 22 to reset to the original height at the front stage of the fifth 60° rotation stroke of the main shaft 6 through the settlement structure. When the compensation frame 22 rises, the just-started rotating bearing frame 26 is lifted, and the stacked whole formed by the four filter single pieces stacked on the upper layer of the bearing frame 26 is higher than the lowest end of the inclined plane of the connecting plate 3, so as to prevent the conveying system from not being shut down in time, resulting in the fifth filter single piece impacting the stacked whole formed by the neatly stacked four filter single pieces and causing the neatly stacked four filter single pieces to be disordered; if the situation that the conveying system fails to be shut down in time occurs, the production line personnel should immediately remove the fifth filter single piece after the delayed shutdown conveying system stops (because the fifth filter single piece is blocked by the stacked whole of the first four pieces and will only stay on the connecting plate 3, and there is no safety risk during the removal process); it should be noted that during the process of the main shaft 6 rotating the fifth 60°, the compensation frame 22 first rises to the highest point and then remains stationary.

[0063] During the process of the main shaft 6 driving the rotating member 7 and the rotating sprocket 701 to rotate the sixth 60°, the clamping post 8 moves from the tooth top of the rotating sprocket 701 along the spiral surface to the tooth root on one side of the spiral surface; at the same time, under the action of the first compression spring 12, the clamping post 8, the clamping sleeve 9, and the flat key 902 perform a reverse spiral motion along the groove 901 under the action of the roller 11, returning to their initial positions, thereby causing the turning shaft 16, the bracket 17, and the bearing frame 26 to return to their initial positions; keep the compensation frame 22 still at the highest position.

[0064] In this way, a complete packaging and boxing cycle of the four-piece filter monomer is completed.

[0065] As a further solution of the present invention, the settlement structure includes a secondary shaft 19 rotatably arranged in the bin body 4, the secondary shaft 19 is connected to the main shaft 6 through a plurality of transmission belts 18, the transmission belts 18 are synchronous belts, and the transmission ratio between the main shaft 6 and the secondary shaft 19 is 1:1; An irregular-shaped wheel 20 is mounted on the auxiliary shaft 19. The irregular-shaped wheel 20 includes a cylindrical portion 2001 and a spiral portion 2002, and each of the cylindrical portion 2001 and the spiral portion 2002 occupies half of the irregular-shaped wheel 20. A roller 21 is rotatably arranged on the compensation frame 22. The roller 21 is in rolling cooperation with the irregular-shaped wheel 20, and a supporting portion 2201 is formed at one end of the compensation frame 22. The supporting portion 2201 passes through the bracket 17 and cooperates with the bearing frame 26. Wherein, a guide rod 23 is installed at the lower part of the compensation frame 22, a guide sleeve 24 slidably matched with the guide rod 23 is installed at the bottom of the bin body 4, and a second compression spring 25 is sleeved on the outer periphery of the guide rod 23. One end of the second compression spring 25 abuts against the guide sleeve 24, and the other end abuts against the top of the guide rod 23. It should be noted that a perforation is formed at the bottom of the bin body 4, which penetrates the bottom of the bin body 4 and is concentric with the guide sleeve 24 for the guide rod 23 to slide through.

[0066] During the first 60° rotation of the main shaft 6, the roller 21 is in stroke cooperation with the last 60° of the cylindrical portion 2001. Therefore, the roller 21 will not sink, that is, the compensation frame 22 will not sink, ensuring that the bearing frame 26 supported by the supporting portion 2201 will not sink. During the second 60° stroke of the rotation of the main shaft 6, the roller 21 cooperates with the spiral portion 2002, driving the roller 21 and the compensation frame 22 to sink by the thickness of a single filter sheet and compressing the second compression spring 25. Similarly, during the third and fourth 60° strokes of the rotation of the main shaft 6, the roller 21 and the compensation frame 22 sink by the thickness of a single filter sheet respectively, further compressing the second compression spring 25. During the fifth 60° stroke of the rotation of the main shaft 6, the second compression spring 25 rebounds to cause the roller 21 to drive the compensation frame 22 to reset to the original height at the front stage of this rotation stroke. During the sixth 60° rotation of the main shaft 6, the compensation frame 22 remains stationary at the highest position.

[0067] In addition, the present invention also proposes a method for packaging and boxing the finished product of the stacked filter monomer by using the packaging and boxing device on the automatic production line as described above, so as to realize horizontally stacking multiple filter single sheets to a predetermined number of sheets (or thickness), then flipping 90° and vertically loading them into a box frame adapted thereto for overall packaging. The specific steps are as follows: Step 1, matching and debugging. According to the stacking quantity, debug the interval conveying parameters of the conveying system and the operating parameters of the stepping motor 5. Among them, the interval conveying parameters of the conveying system include the conveying rate and the intermediate stop parameters. Step 2, state debugging. Check the initial positions of each component, including the corresponding relationship of the initial positions of the rotating part 7, the clamping column 8, the irregular-shaped wheel 20, and the manipulator 29. Step 3: Production line connection. Connect the starting end of the conveying system to the ending end of the production line of the single filter piece. Step 4: Production debugging. Pre-start the stepper motor 5 and the conveying system, and check the smoothness of the packaging process and the correctness of the connection of each process. Step 5: Officially start the packaging and boxing production. Trained production line personnel and subsequent transfer personnel after boxing can be arranged for this step.

[0068] The above embodiments are exemplary rather than restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
