[0002] Environmentally friendly paper bags are generally packaging bags made of recyclable paper or renewable resources to reduce pollution and damage to the environment, and have been widely used in production and life. As packaging products, environmentally friendly paper bags need to be transported to the packaging and storage area in the actual production process. In the transportation process, in order to facilitate the subsequent centralized stacking or centralized batch packing, the paper bags need to be centralized sorted and packaged. Specifically, the finished paper bags need to be stacked and stacked in batches, and then the stacked paper bags are fixed and packaged by tying. The tying is mostly done with rubber bands, and then they are centralized and transferred to the storage area.

[0003] In small and medium-sized paper bag production enterprises, finished paper bags are generally automatically stacked during the transportation process, but the stacked paper bags need to be taken out manually, and the whole stack of paper bags need to be sorted, aligned and compacted, and then manually inserted with rubber bands to complete the binding and fixation, and finally transported to the storage area through the next section of the conveyor belt. In actual operation, it often requires the collaboration of multiple people, and each person needs to complete at least one or more repeated operations of taking out the whole stack of paper bags, sorting the paper bags, compacting the paper bags and tying the paper bags, which wastes manpower and requires manual labor to perform a large number of simple repetitive operations.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, an environmentally friendly paper bag finished product automatic conveying equipment includes a workbench 1, on which is mounted a conveyor unit 2 for driving paper bags to be conveyed one by one, the conveyor unit 2 includes a conveyor frame 21 welded to the workbench 1, on which is mounted a horizontal conveying belt conveyor 22, and on which is mounted a conveying roller unit 23 at the conveying port of the belt conveyor 22 on the conveyor frame 21; the conveying roller unit 23 includes a main roller 231 and an auxiliary roller 232 which are horizontally rotatably mounted on the conveyor frame 21, and the horizontal conveying section of the main roller 231 Flush with the conveying end surface of the belt conveyor 22, the auxiliary roller 232 is located directly above the main roller 231, and both the main roller 231 and the auxiliary roller 232 can be connected to the motor to realize independent drive; a stacking table 3 for guiding multiple paper bags to be automatically stacked and stacked is installed on the conveyor frame 21; the stacking table 3 is docked and arranged at the lower side of the main roller 231; the stacking table 3 includes a fixed seat 31 welded to the conveyor frame 21 and a stacking plate 32 welded to the fixed seat 31; the stacking plate 32 is an L-plate structure, and the stacking plate 32 is arranged obliquely with the notch facing upward. The belt conveyor 22 is docked with the finished product blanking end of the existing environmentally friendly paper bag making machine, and the finished paper bags will fall on the belt conveyor 22, such as Figure 5 As shown, the paper bag is conveyed from left to right on the belt conveyor 22, the main roller 231 rotates clockwise, and the auxiliary roller 232 rotates counterclockwise. The paper bag passes through the gap between the main roller 231 and the auxiliary roller 232, and falls into the recess of the coding plate 32. When passing through the gap between the main roller 231 and the auxiliary roller 232, the paper bag can be flattened once. Through continuous conveying, multiple paper bags will be stacked in sequence in the recess of the coding plate 32.

[0034] The finished paper bags need to be packaged in batches. When the paper bags stacked on the stacking board 32 reach the predetermined number of batch packaging, the whole stack of paper bags in the stacking board 32 needs to be taken out to facilitate the stacking of the next batch. Therefore, the workbench 1 is equipped with a transfer mechanism 4 for moving the whole stack of paper bags stacked on the stacking table 3 out; it should be noted here that an existing electronic counter can be installed on the conveyor frame 21 to automatically count the paper bags on the belt conveyor 22, thereby counting the stacked paper bags.

[0035] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the transfer mechanism 4 includes a transfer plate 43 and a moving component 42 that drives the transfer plate 43 to move horizontally away from under the coding plate 32; in order to realize the final automatic flipping and unloading, a flip base 41 is installed on the workbench 1, and the moving component 42 includes a slide rail 421 horizontally fixed on the flip axis of the flip base 41 and a sliding base 422 slidably installed in the slide rail 421; the flip base 41 can be driven to flip at a specified angle through an existing angle motor, and the angle motor has a built-in locking structure to achieve position locking after the flip is completed. The transfer plate 43 is composed of a lower support plate 431 and a leaning plate 432 which are welded perpendicular to each other. The lower support plate 431 is welded on the sliding base 422. When the slide rail 421 is in a non-flipping tilted state, the lower support plate 431 and the leaning plate 432 are respectively in a corresponding parallel state with the two flat plate parts of the coding plate 32; a cylinder can be installed at one end of the slide rail 421 (the cylinder is not shown in the accompanying drawings), and the sliding base 422 can be fixed at the output end of the cylinder. The sliding base 422 is pushed by the cylinder to slide along the slide rail 421, thereby driving the transfer plate 43 to move between a position below the coding plate 32 and a position moved out from under the coding plate 32.

[0036] like Figure 8 As shown, a rectangular avoidance notch 4311 is provided on the lower support plate 431; a slide groove 4321 is centrally provided on the plate surface of the inclined plate 432 located inside the notch of the transfer plate 43, and the slide groove 4321 extends to the upper and lower ends along the hypotenuse direction of the inclined plate 432; the inclined push assembly 44 includes an inclined push plate 442 arranged at the avoidance notch 4311, and a sliding portion 4421 that slidably cooperates with the slide groove 4321 is welded on the inclined push plate 442, and the sliding portion 4421 is in a non-convex state in the slide groove 4321, and a No. 1 cylinder 441 is fixed to the outer wall of the inclined support plate 432 through a fixing plate, and the sliding portion 4421 passes through the inclined support plate 432 and is welded to the output end of the No. 1 cylinder 441; in this embodiment, when the output rod of the No. 1 cylinder 441 is in a fully extended state, the plate surface of the lower support plate 431 located inside the notch of the transfer plate 43 is flush with the inclined push plate 442.

[0037] like Figure 5 and Figure 8As shown, a side thrust assembly 45 is mounted on the leaning plate 432; a bevel rail 4322 extending along the bevel direction is welded on one side of the bevel of the leaning plate 432; the side thrust assembly 45 includes a No. 2 cylinder 451 welded and fixed on the bevel rail 4322 and a sliding bar 452 slidably mounted in the bevel rail 4322, and an end plate 453 is relatively vertically welded on the end of the sliding bar 452 away from the lower support plate 431, and the end plate 453 is fixed to the output end of the No. 2 cylinder 451 by bolts. ; A side push plate 454 is welded on one side of the end plate 453 close to the lower support plate 431 and is vertically arranged relative to the lower support plate 431 and the inclined plate 432; when the output rod of the No. 2 cylinder 451 is fully extended, that is, when the sliding bar 452 slides to the farthest position from the lower support plate 431, the side push plate 454 is located outside the recessed area of ​​the coding plate 32. When the transfer plate 43 moves under the coding plate 32 again, the side push plate 454 can avoid the paper bag in the coding plate 32 to avoid pushing the paper bag out.

[0038] like Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, a bag pressing assembly 46 for pressing a whole stack of multiple paper bags against each other is correspondingly mounted on the side pushing assembly 45 . The bag pressing assembly 46 includes a guide column 461 which is vertically slidably mounted on the end plate 453 relative to the inclined plate 432, and a bag pressing plate 462 which is arranged parallel to the inclined plate 432 is welded at one end of the guide column 461. The bag pressing plate 462 is evenly provided with circular holes for facilitating air extrusion when the paper bag is compressed. A return spring 463 is sleeved on the guide column 461, and the two ends of the return spring 463 are respectively welded to the end plate 453 and the bag pressing plate 462; the bag pressing assembly 46 moves synchronously with the side push plate 454 as the sliding bar 452 slides toward the lower support plate 431 from the position farthest from the lower support plate 431, the bag pressing plate 462 moves inward from the outside of the recessed area of ​​the coding plate 32; that is, when the output rod of the No. 2 cylinder 451 is fully extended, when the transfer plate 43 moves under the coding plate 32 again, the bag pressing plate 462 is in a position to avoid the paper bag in the coding plate 32 like the side push plate 454. The bag pressing assembly 46 is also equipped with a pressure assembly 7 for making the bag pressing plate 462 approach the inclined plate 432. The pressure assembly 7 includes a connecting frame 71 welded to the outer wall of the conveyor frame 21, a No. 4 air cylinder 72 fixed to the connecting frame 71 by bolts, and a pressure plate 73 fixed to the output end of the No. 4 air cylinder 72 by bolts, and the extension direction of the output rod of the No. 4 air cylinder 72 is vertically arranged relative to the bag pressing plate 462.

[0039] When the number of paper bags in the stacking plate 32 reaches the number of batches to be bound, as counted by the electronic counter, the transfer mechanism 4 will automatically move the entire stack of paper tapes out of the stacking plate 32. Specifically, first, the No. 2 cylinder 451 drives the sliding bar 452 to slide in the direction close to the lower support plate 431, so that the side push plate 454 and the bag pressing plate 462 are synchronously moved into the recess of the stacking plate 32. At this time, the bag pressing plate 462 acts as a partition plate, so that the entire stack of paper bags to be removed is separated from the next batch of paper bags being stacked. It should be noted here that when the reset spring 463 is not actively compressed, the side push plate 454 is located between the leaning plate 432 and the bag pressing plate 462, that is, the side push plate 454 only makes pushing contact with the entire stack of paper bags to be removed; Figure 6 As shown in the perspective, the moving component 42 then drives the transfer plate 43 to move downward, so that the transfer plate 43 gradually moves out from under the coding plate 32. During the movement, the side push plate 454 moves synchronously with the transfer plate 43, thereby pushing the entire stack of paper bags to move downward. The side push plate 454 also plays a role in arranging and aligning the entire stack of paper bags when pushing sideways. When the transfer plate 43 is completely moved out, the entire stack of paper bags automatically falls from the coding plate 32 to the transfer plate 43, and stops when the transfer plate 43 moves to the right side of the pressure-applying component 7.

[0040] Next, the No. 4 cylinder 72 is started, driving the pressure plate 73 to press against the bag pressing plate 462, and the bag pressing plate 462 presses against the entire stack of paper bags, so that the entire stack of paper bags is compacted. Subsequently, the pressure plate 73 is withdrawn, and under the action of the reset spring 463, the bag pressing plate 462 is reset.

[0041] In this embodiment, similar to the prior art, rubber bands are preferably selected as the binding material to bind and fix the whole stack of paper bags. Different from the existing large-scale paper bag production, conveying and packaging production line, a large disc material sorting machine is not used to sort and convey the rubber bands. Instead, Figure 1 , Figure 3 , Figure 5 and Fig. 9As shown, the workbench 1 is equipped with a pre-storage feeding box 5 for pre-storing rubber bands and pushing the rubber bands one by one; the conveyor unit 2, the pressure component 7 and the pre-storage feeding box 5 are distributed in sequence in the moving direction of the moving component 42; the pre-storage feeding box 5 includes a fixed frame 51 welded on the workbench 1 and a box body 52 fixed on the fixed frame 51, the box body 52 is installed in an inclined manner, and the inclination angle direction of the box body 52 is consistent with the leaning plate 432, the top of the box body 52 is open, and the bottom end of the box body 52 is welded with a box bottom plate 521, and the box bottom plate 521 is fixed to the fixed frame 51 by bolts; a support frame 53 for supporting the rubber bands and arranged one by one is movably inserted and installed in the box body 52, and the box body 52 is also equipped with a stepping pushing component 54 that pushes the support frame 53 to move out of the box body 52 in sections. The material support rack 53 includes a rod seat 531 that slides with the inner wall contour of the box body 52, and four material support rods 532 with rectangular vertices are vertically welded on the rod seat 531. The rubber bands can be manually stretched and sleeved on the four material support rods 532. In order to ensure that the rubber bands are distributed one by one and to facilitate the removal of materials one by one, the material support rods 532 are evenly distributed with limiting grooves 5321 along the axial direction, and the limiting grooves 5321 are annular grooves; the material support rack 53 can be aligned and inserted into the interior of the box body 52, and can also be quickly pulled out. In order to facilitate alternating replacement, a plurality of spare material support racks 53 can be set. The stepping push assembly 54 includes a stepping motor 541 fixed on the bottom plate 521 of the box by screws and a lead screw 542 fixed on the output shaft of the stepping motor 541. The lead screw 542 is rotatably mounted on the outside of the box body 52. ​​A push plate 543 is installed in the box body 52 to slide with its contour, and the push plate 543 is threadedly connected to the lead screw 542. The push plate 543 is located at a more inner position of the box body 52 relative to the support frame 53. The support frame 53 inserted in the box body 52 has its rod seat 531 in close contact with the push plate 543. After the stepping motor 541 is started, the push plate 543 is driven by the lead screw 542 to move in a direction away from the bottom plate 521 of the box, thereby pushing the support frame 53 to move synchronously. The stepping motor 541 is started intermittently, and each time the pushing distance for the support frame 53 is equal to the distribution spacing of the limit slots 5321, so that the rubber bands are pushed out from the box body 52 one by one. Compared with the disc feeder, although the method of using the pre-storage feed box 5 requires manual periodic replenishment, that is, it is impossible to achieve highly continuous processing operations, the pre-storage feed box 5 has a simple structure, is easy to maintain, occupies a small space, and is more suitable for the production and manufacturing of small and medium-sized processing workshops. It is also convenient for taking out the rubber bands one by one. In addition, the rubber band itself has great viscosity and is a flexible material. If a disc feeder is used for material sorting and transportation, a large number of rubber bands are also prone to entanglement and sticking to each other.

[0042] like Figure 1 , Figure 4 and Figure 5As shown, in order to realize the automatic tying of paper bags by rubber bands, the workbench 1 is also equipped with a tying actuator 6 for tying a whole stack of paper bags by rubber bands. The tying actuator 6 includes a displacement frame 61 fixed on the workbench 1, and the displacement frame 61 includes a vertical frame 611 welded on the workbench 1, and a transverse rail 612 arranged parallel to the slide rail 421 is welded on the vertical frame 611, and an oblique rail 613 is slidably installed on the transverse rail 612, and the guiding direction of the oblique rail 613 is vertically arranged relative to the plate surface of the lower support plate 431, and a tying manipulator 62 for opening and grasping the rubber band is slidably installed on the oblique rail 613; in this embodiment, the sliding of the oblique rail 613 along the transverse rail 612 and the sliding of the tying manipulator 62 along the oblique rail 613 can be driven by assembling a cylinder, and it should be pointed out that the cylinder is not shown in the drawings.

[0043] like Figure 1 , Figure 4 and Fig.10 As shown, the tying robot 62 includes a carrying frame 63 sliding along the inclined rail 613, and a guide plate 64 is fixed to the lower end of the carrying frame 63 by screws. Four guide holes 641 are opened on the guide plate 64. The guide holes 641 are long holes, and the four opening rods 65 are distributed in the form of rectangular vertices; the layout of the four guide holes 641 is not described here, and the specific layout can be seen Figure 4As shown; a spreading rod 65 is slidably provided in each of the four guide holes 641. When the rubber band is obtained from the pre-stored feeding box 5 by the tying manipulator 62, in order to allow the guide hole plate 64 to avoid the spreading rod 532 that is continuously pushed out from the box body 52, in this embodiment, the part of the spreading rod 65 that extends downward from the guide hole plate 64 is lengthened; the carrying frame 63 is equipped with a spreading drive assembly 66 that synchronously drives the four spreading rods 65 to slide; the spreading drive assembly 66 includes a No. 3 cylinder 661 fixed to the carrying frame 63 by bolts, and a No. 3 cylinder 661 is fixed to the carrying frame 63 by bolts. The output end of the cylinder 661 is hinged with two connecting rods 662, and the other ends of the two connecting rods 662 are hinged with sliders 663. The guide hole plate 64 is provided with a guide groove 642 which is arranged parallel to the transverse rail 612. The two sliders 663 are arranged opposite to each other and slidably installed in the guide groove 642. Guide rods 664 are welded on the two sliders 663, and the guide rods 664 are arranged perpendicularly to the sliding direction of the sliders 663. Two spreading rods 65 are slidably installed on one of the guide rods 664, and the other two spreading rods 65 are slidably installed on the other guide rod 664. When the No. 3 cylinder 661 is started, the two sliders 663 can be driven to slide along the guide groove 642 through the two connecting rods 662. When the two guide grooves 642 slide back to back, the slider 663 can drive the expansion rod 65 to move along the guide hole 641 through the guide rod 664. The expansion rod 65 moves away from the distribution center of the four guide holes 641 in the direction of the guide groove 642 and perpendicular to the direction of the guide groove 642, so that the four expansion rods 65 are in an outward expansion state. On the contrary, when the two sliders 663 slide close to each other, the four expansion rods 65 are in an inward contraction state.

[0044] In the process of moving the transfer plate 43 out from under the code plate 32, the tying actuator 6 synchronously completes the taking of the rubber band from the pre-stored feeding box 5, so as to Figure 6 As shown in the perspective, specifically, the tying robot 62 moves downward along the transverse rail 612 along the oblique rail 613, so that the tying robot 62 moves from the right side position of the pressure component 7 to the right side position of the pre-stored feeding box 5; Figure 5 As shown in the perspective, under the push of the stepping pushing assembly 54, the support frame 53 moves obliquely upward along the inner contour of the box body 52, completing the removal and pushing of a single rubber band, and the tying robot 62 then moves downward along the oblique moving rail 613 to the lowest position, so that the front end position of the four spreading rods 65 extends into the circle of the rubber band, and then, the spreading drive assembly 66 drives the four spreading rods 65 to move outward, and the rubber band is further spread and deformed through the four spreading rods 65, and separated from the four supporting rods 532, thereby completing the spreading and grasping of the rubber band, and then, the tying robot 62 moves upward along the oblique moving rail 613 to reset, and the oblique moving rail 613 moves and resets along the transverse moving rail 612, so that the tying robot 62 moves to the Figure 6It is shown in the figure at the right side of the pressure assembly 7. It should be added that the size of the rubber band on the tying manipulator 62 can be fully inserted into a whole stack of paper bags.

[0045] When the whole stack of paper bags is compacted and the rubber bands are removed, the paper bags can be tied. Specifically, first, the No. 1 cylinder 441 is started, thereby pushing the whole stack of paper bags to move obliquely upward through the oblique push plate 442, so that the upper aligned end of the whole stack of paper bags is synchronously extended outward from the oblique support plate 432; then, the tying robot 62 moves downward along the oblique rail 613, so that the rubber band in the expanded state is smoothly inserted into the whole stack of paper bags, and then, the expansion drive assembly 66 drives the four expansion rods 65 to retract and move closer, and then the rubber band is automatically tightened on the whole stack of paper bags, and then, the tying robot 62 moves upward along the oblique rail 613, and the expansion rod 65 is immediately pulled out of the rubber band; after the tying is completed, the oblique push plate 442 is reset, and the whole stack of paper bags falls back into the transfer plate 43 again, and then, the flip base 41 drives the moving assembly 42 and the transfer plate 43 to flip as a whole, so that the tied paper bags are automatically unloaded from the transfer plate 43. It should be added that Figure 6 As shown, a conveyor or a collection box may be arranged below the pressure-applying assembly 7 to further convey or centrally collect the unloaded paper bags.

[0046] An environmentally friendly automatic conveying device for finished paper bags is provided with a conveying unit 2 and a stacking table 3 that cooperate with each other, which can realize automatic guidance and stacking of paper bags. A transfer mechanism 4 is provided in cooperation with the stacking table 3, which can replace manual work to automatically remove a whole stack of paper bags, and can synchronously arrange and align the whole stack of paper bags during the removal process through a side push component 45 provided in the transfer mechanism 4. Through the bag pressing component 46 provided in the transfer mechanism 4 and in cooperation with a pressure applying component 7, the whole stack of paper bags can be automatically pressed and compacted instead of manual work; a pre-storage feeding box 5 is provided, which can pre-arrange and store rubber bands and automatically push them, and a matching The binding actuator 6 can automatically align and pick up the rubber band relative to the pre-stored feeding box 5, and can also cooperate with the oblique push assembly 44 provided in the transfer mechanism 4 to replace manual labor to complete the automatic binding and fixation of the whole stack of paper bags. In addition, the bound paper bags can be automatically unloaded. In summary, the conveying equipment provided by the present invention has a simple and compact structure, and can replace manual labor to synchronously complete a series of operations of taking out, sorting, compacting and binding of batches of paper bags during the conveying and transferring of finished paper bags. Manual labor only needs to replenish the rubber band in time, which reduces manpower, improves sorting efficiency, and avoids a large number of simple and repetitive manual operations.
