Description

Technical Field

[0001] The present invention relates to a material packaging machine, specifically a packaging and boxing device and its packaging method on an automated production line for laminated filter monomers as finished products. Background Art

[0002] High-efficiency air filters mainly include two main structures: a filter element and a casing. As the most important structure for filtration, the filter element is generally made of ultra-fine chemical fibers and glass fiber materials; while the casing 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 filtering principle of high-efficiency air filters is to intercept the 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 pieces are stacked to form a filter monomer, and folds are formed between adjacent two filter single pieces, thereby increasing the windward area. After stacking multiple filter single pieces and loading them into a housing, a filter monomer is formed; among them, the more the number of filter single pieces in the filter monomer, the better the filtering effect. For example, most household fresh air conditioners use three filter single pieces stacked to form a filter monomer, while in the on-vehicle air conditioner filter elements of high-end new energy vehicles, generally four filter single pieces are stacked to form a filter monomer.

[0004] On the production line of high-efficiency air filters, a predetermined number of filter single pieces need to be vertically and neatly loaded into the casing from the side of the casing for packaging, so as to prevent the multiple filter single pieces in the filter monomer from scattering and separating. However, in the actual production environment, the filter single pieces are produced one by one; currently on the production line, each filter single piece is turned to the vertical position by a flipping workbench and then loaded into the casing in sequence. On the one hand, the rate of loading one by one does not match the production rate of the filter single pieces (the loading rate is lower than the production rate), and the production rate has to be slowed down; on the other hand, during the loading process, since the position of the flipping workbench remains unchanged, therefore, a casing moving system needs to be adapted to adjust the position of the casing according to the process of vertically stacking the filter single pieces one by one. During the vertical stacking process, a manipulator needs to always press the filter single piece at the end of the stack; when the next filter single piece 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 pieces that were originally vertically and neatly stacked become unstable and loose again, interfering with the insertion of the next filter single piece.

[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 function of vertical and neat stacking. 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 to be stacked with the multiple stacked filter pieces; and after the current filter single piece is stacked, it needs to be switched to the rear mechanical arm to keep the multiple filter pieces pressed, while the front mechanical arm is switched to push the next filter single piece; the two mechanical arms alternate and operate alternately, and interference problems often occur.

Specific implementation mode

[0065] 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.

[0066] 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;

[0067] A conveying system is arranged on the bin body 4 along its length direction for conveying the single-piece filter finished products from the starting end of the bin body 4 to the other end one by one;

[0068] A stacking mechanism is arranged at the conveying end of the conveying system. The stacking mechanism is installed on the bin body 4, and the stacking mechanism is matched with the turning mechanism;

[0069] When the number of single-piece filters stacked on the stacking mechanism reaches a predetermined number (that is, after reaching a predetermined thickness), the turning mechanism drives the stacking mechanism and the multiple single-piece filters stacked on the stacking mechanism to turn 90°, so that the single-piece filter finished products of the predetermined number are vertically loaded into the single-piece frame.

[0070] In this embodiment, in the present invention, the mutual cooperation between the stacking mechanism and the turning mechanism is realized by means of cooperation, so that the stacking and turning actions are alternately performed, 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.

[0071] 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 rotating shaft sleeve 13 movably arranged in the bin body 4;

[0072] The rotating shaft sleeve 13 is in sliding fit with the ferrule 9, and the ferrule 9 is elastically sleeved outside the fixed shaft 10. The fixed shaft 10 is installed in the bin body 4, and the rotating shaft sleeve 13 is rotatably connected to the fixed shaft 10 through a bearing;

[0073] A clamping post 8 is installed on the outside of the ferrule 9 perpendicular to its axis direction. The clamping post 8 is matched with the rotating clamping teeth 701 formed on the rotating member 7. One side of the rotating clamping teeth 701 is a helical surface, and the other side is a flat surface;

[0074] When the rotating member 7 and the rotating clamping teeth 701 rotate until the flat surface abuts against the clamping post 8, the flat surface of the rotating clamping teeth 701 can drive the clamping post 8 and the ferrule 9 to rotate, and elastic potential energy is stored during the rotation of the ferrule 9; when the flat surface of the rotating clamping teeth 701 passes over the clamping post 8, the elastic potential energy is released to drive the ferrule 9 and the clamping post 8 to reverse and reset.

[0075] In this embodiment, referring to Figure 16 the rotation direction of the rotating member 7 given in the attached figure, it can be seen that the rotating clamping teeth 701 are not always in cooperation with the clamping post 8. In the initial state, the clamping post 8 is located at the tooth root on the side of the helical surface; during most of the rotation of the rotating member 7, the rotating clamping teeth 701 are not in cooperation with the clamping post 8; in this way, the rotation movement of the rotating member 7 in the previous cycle will not cause any movement of the ferrule 9, and only when the flat surface of the rotating clamping teeth 701 driven by the rotating member 7 rotates to abut against the clamping post 8, will the clamping post 8 be driven to move.

[0076] As a further solution of the present invention, a helical groove 901 is formed on the inner wall of the ferrule 9, an insertion hole 1001 is provided on the fixed shaft 10, a roller 11 is fitted in the insertion hole 1001, and the roller 11 is in rolling fit with the groove 901;

[0077] 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 ferrule 9, and the other end of the first compression spring 12 abuts against the step;

[0078] Among them, the arc length occupied by the rotating clamping teeth 701 on the circumference of the rotating member 7 is 1 / 6 of the circumference, and when the clamping post 8 is separated from the flat surface of the rotating clamping teeth 701, the roller 11 rolls from one end of the groove 901 to the other end.

[0079] For a better and more concrete illustration, the examples given in the attached drawings of the specification of the present invention are used as an explanation; the arc occupied by the rotating engaging teeth 701 on the circumference of the rotating member 7 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 slot 901 is also h.

[0080] Among them, the rotating member 7 rotates once every 60°, that is, the rotating member 7 performs an intermittent rotation behavior. It will stop every time it rotates 60°. After a predetermined time interval, it will rotate 60° again and stop again, and so on in a cycle.

[0081] Combined with the attached Figure 21 As can be seen, after the rotating member 7 and the rotating engaging teeth 701 rotate from the current position to contact the column 8 on the flat surface, the continuously rotating rotating engaging teeth 701 cooperate with the column 8 by means of the flat surface on one side thereof, and drive the column 8 and the sleeve 9 to rotate; during the rotation of the sleeve 9, due to the cooperation of the roller 11, the slot 901 and the through hole 1001, the sleeve 9 rotates while moving along the spiral direction of the slot 901 and continuously compresses the first compression spring 12. Therefore, the sleeve 9 and the column 8 perform a spiral movement during this process. Therefore, the column 8 moves from the tooth root to the tooth tip compared with the flat surface.

[0082] During the process that the flat surface on one side of the rotating engaging teeth 701 contacts the column 8 at the tooth root and moves to fit the column 8 at the tooth tip, the rotating engaging teeth 701 rotate an angle of 60°, and the roller 11 also rolls from one end of the slot 901 to the other end; the rotating engaging teeth 701 then stop. At this time, the column 8 stays at the tooth tip of the rotating engaging teeth 701; after a predetermined time interval, the rotating engaging teeth 701 rotate again. At this time, the column 8 has passed over the tooth tip and moves back along the spiral surface under the elastic force of the first compression spring 12, driving the sleeve 9 to reverse and reset; at the same time, the roller 11 also resets to the initial end of the slot 901.

[0083] 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 stepping motor 5 is installed on one side outside the housing 4, and the output shaft of the stepping motor 5 is connected to the main shaft 6.

[0084] In this embodiment, the output shaft of the stepping motor 5 controls the main shaft 6 to rotate 60° each time, and further drives the rotating member 7 to rotate once every 60°; it is realized that the rotating member 7 stops every time it rotates 60°, and after a predetermined time interval, it rotates 60° again; and so on in a cycle, stepping and rotating every 60° in one direction.

[0085] As a further solution of the present invention, a keyway 1301 is axially formed on the inner wall of the follower rotating 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;

[0086] A large gear 14 is installed outside the follower rotating sleeve 13, the large gear 14 meshes with a small gear 15, and the small gear 15 is installed on the turnover shaft 16; the turnover shaft 16 is rotatably arranged in the bin body 4, and the stacking mechanism is connected to the turnover shaft 16.

[0087] 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 sleeve 13 rotatably installed on the fixed shaft 10 through a bearing to rotate, and then drive 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 groove 901 to the other end of the groove 901, the large gear 14 drives the small gear 15 to rotate 90°.

[0088] 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 turnover shaft 16;

[0089] A carrier 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 turnover shaft 16;

[0090] The conveying system includes a conveyor belt 2, and one end of the travel of the conveyor belt 2 is docked with the carrier 26 through an adapter plate 3, and the adapter plate 3 is installed in the bin body 4 through a cross shaft.

[0091] In this embodiment, the single filter pieces intermittently conveyed by the conveyor belt 2 in the conveying system fall onto the carrier 26 one by one through the adapter plate 3; after the single filter pieces on the carrier 26 are stacked to a predetermined number (i.e., a predetermined thickness), the turnover shaft 16 drives the bracket 17 to turn over, and finally drives the carrier 26 and the multiple stacked single filter pieces thereon to turn over 90°, changing from horizontal stacking to vertical stacking.

[0092] The guardrail provided can ensure that during the turnover process of the multiple single filter pieces, the edges of each piece always fit the guardrail, thereby ensuring neat edges.

[0093] As a further solution of the present invention, a side beam 27 is installed on one side of the bin body 4, and two groups of limit posts 28 are arranged on the side beam 27, and the two groups of limit posts 28 are arranged in the vertical direction;

[0094] A manipulator 29 is arranged on the other side of the bin body 4;

[0095] When the carrier 26 and multiple stacked filter single pieces thereon are flipped by 90°, the multiple filter single pieces are clamped by the carrier 26 and the limit posts 28.

[0096] In this embodiment, when the carrier 26 and multiple stacked filter single pieces thereon are flipped by 90°, one side of the stacked whole formed by the multiple filter single pieces is restricted by the carrier 26, and the other side is limited by two groups of limit posts 28. Therefore, there is no gap between the multiple filter single pieces; and at this time, the manipulator 29 is located on one side of the vertical stacked whole and is facing the center of the whole; by opening the manipulator 29 and continuously approaching and clamping the stacked whole, the stacked whole is clamped and sent outside the bin body 4, and finally the vertically stacked whole of neatly stacked multiple pieces is loaded into the box frame structure, completing the packaging and boxing work.

[0097] As a further solution of the present invention, a sliding hole is provided on the bracket 17, and the sliding hole is in sliding fit with a sliding rod 2601 fixedly arranged on the carrier 26;

[0098] The stacking mechanism further includes a compensation frame 22 that is liftably arranged in the bin body 4, and the compensation frame 22 cooperates with the carrier 26; the compensation frame 22 is connected to the main shaft 6 through a settlement structure, and during the process that the main shaft 6 rotates and the clamping sleeve 9 is stationary, the settlement structure drives the carrier 26 to intermittently move downward, and the height of its single downward movement is equal to the thickness of the filter single piece.

[0099] In this embodiment, taking the example shown in the drawings of the specification, during the process that the main shaft 6 drives the rotating member 7 and the rotating engaging teeth 701 to rotate the first 60°, the clamping sleeve 9 remains stationary; at the same time, 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 inclined plane of the connecting plate 3 is the thickness of one filter single piece; the first filter single piece sent by the conveyor belt 2 falls onto the carrier 26 through the connecting plate 3;

[0100] During the process that the main shaft 6 drives the rotating member 7 and the rotating engaging teeth 701 to rotate the second 60°, the clamping sleeve 9 still remains stationary; at the same time, the main shaft 6 drives the compensation frame 22 to move downward by the thickness of one filter single piece through the settlement structure. After the compensation frame 22 moves downward, the carrier 26 also moves downward by the thickness of one filter single piece under the action of gravity, so as to keep the height of the first filter single piece falling onto the carrier 26 equal to the initial highest position of the carrier 26, avoiding that the second filter single piece cannot be stacked on the first filter single piece due to too small height difference; or that the second filter single piece generates more friction and position deviation due to too large path during the process of being stacked onto the first filter single piece, or that due to the reason of frictional resistance, the stacking is not sufficient and there is a large gap between adjacent two filter single pieces, thus affecting the normal stacking of the next filter single piece.

[0101] During the process that the main shaft 6 drives the rotating member 7 and the rotating engaging teeth 701 to rotate the third 60°, the bushing 9 still remains stationary; meanwhile, the main shaft 6 drives the compensation frame 22 to move down by the thickness of another filter single piece through the settlement structure, and the carrier frame 26 also moves down by the thickness of another filter single piece, so as to keep the height of the second filter single piece falling onto the carrier frame 26 equal to the initial highest position of the carrier frame 26, avoiding that the third filter single piece cannot be stacked on the second filter single piece; or the third filter single piece is offset during the process of being stacked onto the second filter single piece.

[0102] During the process that the main shaft 6 drives the rotating member 7 and the rotating engaging teeth 701 to rotate the fourth 60°, the bushing 9 still remains stationary; meanwhile, the main shaft 6 drives the compensation frame 22 to move down by the thickness of another filter single piece through the settlement structure, and the carrier frame 26 also moves down by the thickness of another filter single piece, so as to ensure that the fourth filter single piece can be smoothly stacked on the third filter single piece.

[0103] At the beginning of the main shaft 6 driving the rotating member 7 and the rotating engaging teeth 701 to rotate the fifth 60°, the conveying system stops conveying new filter single pieces through the connecting plate 3 (intermittent program shutdown) by setting the operating parameters; during the process that the rotating engaging teeth 701 rotate the fifth 60°, the flat surface on one side of the rotating engaging teeth 701 cooperates with the clamping post 8, and drives the clamping post 8, the bushing 9, and the flat key 902 to perform a spiral movement along the slot 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 bushing 9 continuously approaches the step on the fixed shaft 10 and further compresses the first compression spring 12; meanwhile, the flat key 902 drives the follower rotating shaft sleeve 13 to only perform a rotational movement by cooperating with the key slot 1301; the follower rotating shaft sleeve 13 drives the small gear 15 to rotate through the large gear 14, and finally drives the turning shaft 16, the bracket 17, and the carrier frame 26 to rotate 90°; meanwhile, 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 carrier frame 26 is lifted, and the stacked whole formed by the four filter single pieces stacked on the upper layer of the carrier frame 26 is higher than the lowest end of the slope surface 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 is not shut down in time occurs, the production line personnel should immediately remove the fifth filter single piece after the conveying system that is delayed in shutdown 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 fifth 60° rotation of the main shaft 6, the compensation frame 22 first rises to the highest point and then remains stationary.

[0104] During the process that the main shaft 6 drives the rotating member 7 and the rotating engaging teeth 701 to rotate by the sixth 60°, the clamping post 8 moves from the tooth top of the rotating engaging teeth 701 along the spiral surface to the tooth root on one side of the spiral surface; meanwhile, under the action of the first compression spring 12, the clamping post 8, the clamping sleeve 9, and the flat key 902 move along the slot 901 in a reverse spiral motion under the action of the roller 11, and return to their initial positions, thereby enabling the turning shaft 16, the bracket 17, and the carrier 26 to return to their initial positions; and the compensation frame 22 still remains at the highest position.

[0105] Thus, a complete packaging and boxing cycle of a four-piece filter monomer is completed.

[0106] As a further solution of the present invention, the settling structure includes a secondary shaft 19 rotatably arranged in the housing 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;

[0107] An irregular-shaped wheel 20 is installed on the secondary shaft 19, the irregular-shaped wheel 20 includes a cylindrical portion 2001 and a spiral portion 2002, and the cylindrical portion 2001 and the spiral portion 2002 each account for half of the irregular-shaped wheel 20;

[0108] 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, and the supporting portion 2201 passes through the bracket 17 and cooperates with the carrier 26;

[0109] 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 housing 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;

[0110] It should be noted that a through hole is provided at the bottom of the housing 4, which penetrates the bottom of the housing 4 and is concentric with the guide sleeve 24 for the guide rod 23 to slide through.

[0111] During the first 60° rotation of the main shaft 6, the roller 21 cooperates with the last 60° stroke of the cylindrical portion 2001. Therefore, the roller 21 does not sink, that is, the compensation frame 22 does not sink, ensuring that the carrier frame 26 supported by the supporting portion 2201 does not sink. During the second 60° stroke of the rotation of the main shaft 6, the roller 21 cooperates with the spiral portion 2002, and the roller 21 and the compensation frame 22 are driven to sink by the thickness of a single filter sheet and compress 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 each, further compressing the second compression spring 25. During the fifth 60° stroke of the rotation of the main shaft 6, the roller 21 drives the compensation frame 22 to reset to the original height at the front stage of this rotation stroke through the rebound of the second compression spring 25. During the sixth 60° rotation of the main shaft 6, the compensation frame 22 is kept stationary at the highest position.

[0112] 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 automated production line as described above, so as to realize that after stacking multiple filter single sheets horizontally to a predetermined number of sheets (or thickness), they are flipped 90° and vertically loaded into a box frame adapted to them for overall packaging. The specific steps are as follows:

[0113] 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 speed and the intermediate stop parameters.

[0114] 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 special-shaped wheel 20, and the manipulator 29.

[0115] Step 3, production line connection. Connect the conveying start end of the conveying system to the production line end of the filter single sheet.

[0116] Step 4, production debugging. Pre-start the stepping motor 5 and the conveying system, and check the smoothness of the packaging process and the correctness of the connection of each process.

[0117] Step 5, officially start the packaging and boxing production. This step can be equipped with trained production line personnel and subsequent transfer personnel after boxing.

[0118] The above embodiments are exemplary and not 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.
