Description

Technical Field

[0001] The present invention relates to the field of distribution and packing lines, and in particular to an intelligent empty box distribution and packing line. Background Art

[0002] With the development of society, products need to be packaged and boxed before storage or transportation. Traditionally, this method is mainly done manually. After the products are packaged into independent packages, they are manually placed in empty boxes and then sealed. This operation method has the disadvantages of low packaging efficiency, low boxing efficiency, high labor intensity for workers and high labor costs for enterprises. Later, some packing lines appeared on the market, which were mainly composed of a packaging box conveyor line, a case opener, a packaging product conveyor line, a case packer and a full box product conveyor line. A case packer must be equipped with a packaging box conveyor line, a case opener, a packaging product conveyor line and a full box product conveyor line, which leads to problems such as complex structure, large space occupation and high production cost, which is not conducive to the development of large-scale case packing industry; and the case openers on the market generally open the box sideways, and the case packers also need to pack the empty boxes sideways. The sideways packing leads to the problems of uneven packing, low packing efficiency and poor packing effect of the packaged products. If the empty box mouth needs to be adjusted upward, it is necessary to add corresponding equipment to complete the adjustment of the swing direction of the empty box, which leads to an increase in the space occupied by the case packing line and an increase in the cost of the equipment. In addition, the increase in the process of adjusting the swing direction of the empty box will reduce the packing efficiency. Summary of the invention The purpose of the present invention is to overcome the deficiencies of the prior art and provide an intelligent empty box delivery and packing line.

[0042] Preferably, a full box blocker and a full box transmission photoelectric sensor are provided in sequence at positions corresponding to the transplanting mechanism of the lower full box roller line.

[0043] By adopting the above-mentioned technical scheme, when the transplanting mechanism needs to transplant the full box to the lower full box roller line, the full box blocker blocks the full box transmitted by the lower full box roller line. After the lower full box roller line receives the full box transplanted by the transplanting mechanism and starts to transmit, the full box blocker releases the full box currently blocked by it; when the current full box transmission photoelectric sensor detects that the corresponding position on the lower full box roller line is transmitting a full box, the transplanting mechanism suspends transplanting the full box to the lower full box roller line. When the full box passes the current full box transmission photoelectric sensor, the full box blocker blocks the subsequent full box transmitted, and the transplanting mechanism resumes transplanting the full box to the lower full box roller line. After the lower full box roller line receives the full box transplanted by the transplanting mechanism and starts to transmit, the full box blocker releases the subsequent full box transmitted by the lower full box roller line. Through the box blocker and the full-box transmission photoelectric sensor, the lower-level full-box roller line is cooperated to collect and convey the full boxes in an orderly and efficient manner. By adjusting the speed of the lower-level full-box roller line to send empty boxes, one lower-level full-box roller line can collect and convey the full boxes sent by multiple transplanting mechanisms. This ensures that the lower-level full-box roller line can convey full boxes smoothly without retention, and the full box recovery is efficient, and the cost is reduced, so as to solve the problems of complex structure, large space and high production cost caused by the current case packing line on the market that each case packing machine must be equipped with a full-box product conveying line (that is, multiple case packing machines must be equipped with multiple full-box product conveying lines).

[0044] Preferably, a controller or PLC control system is provided for signal control with components such as the upper empty box roller line, the lower full box roller line, the case packing machine, the empty box distribution mechanism, the dual servo material sorting mechanism, the product conveying line, the case feeding mechanism, the case positioning mechanism, the case pushing mechanism, the case packing mechanism, the case removing mechanism, the transplanting mechanism and the vacuum pumping mechanism. The controller is a PLC programmable logic controller, which may adopt a programmable logic controller of model XDS-40T-D, but is not limited to this.

[0045] It should be noted that the first positive and negative thread connecting rod assembly and the second positive and negative thread connecting rod assembly both include positive and negative thread connecting rods, and both ends of the positive and negative thread connecting rods are connected with internal threaded external connecting rod fisheye joints or rod end spherical bearings. The box feeding roller line, the upper empty box roller line and the lower full box roller line are all functional descriptions of the roller line. Their specific structure and working principle are common knowledge and will not be explained in detail here. The first photoelectric sensor, the second photoelectric sensor, the third photoelectric sensor, the fourth photoelectric sensor, the middle photoelectric sensor, the lower photoelectric sensor, the forced stop photoelectric sensor, the box arrival photoelectric sensor, the backlog photoelectric sensor, the storage box photoelectric sensor and the full box transmission photoelectric sensor are all functional descriptions of the photoelectric sensor, and they can all use proximity sensors with model M18, but are not limited to this.

[0046] Compared with the existing technology, the beneficial effects of the present invention are as follows: 1. Its overall structural design can realize the automatic loading and conveying of empty boxes and packaged products on a distribution line, automatically detect the length and weight of the packaged products being conveyed, automatically unload and reject the packaged products that do not meet the requirements, automatically group and gather the packaged products that meet the requirements, automatically reserve empty boxes, automatically supply empty boxes in an orderly manner according to the detected box shortage status, automatically position the empty boxes before packing, automatically unpack the empty boxes, automatically fill the empty boxes with packaged products, and automatically gather, convey and unload the full boxes filled with packaged products for recycling. It can realize the automatic unpacking of the box cover from the top of the empty box and the automatic loading of packaged products from the top of the empty box without adding a structure for adjusting the swing direction of the empty box, so as to overcome the problems of the existing box unpacking machine that can only pack the empty boxes sideways, resulting in uneven packing, low packing efficiency and poor packing effect.

[0047] 2. The structure of the product conveyor line is designed so that the distance between the first photoelectric sensor and the second photoelectric sensor can be adjusted through the weighing conveyor mechanism to be suitable for detecting packaged products of different lengths and to determine whether the product meets the packing requirements by measuring the weight of the product; the rejecting conveyor line is pulled by the rejecting cylinder of the rejecting conveyor mechanism to swing downward around the first rotating axis to remove and reject unqualified packaged products, and the downwardly inclined end of the injection conveyor belt line of the injection conveyor mechanism is adjusted to dock with the double servo material sorting mechanism. The injection conveyor belt line cooperates with the side conveyor belt line to increase the friction with the packaged products, so that the packaged products can be quickly transmitted to the double servo material sorting mechanism to ensure that the packaged products are delivered to the double servo material sorting mechanism in place.

[0048] 3. The structure of the dual-servo material sorting mechanism is designed so that it can receive the packaged products from the injection conveying mechanism in a circular manner through the first circulation line and the second circulation line respectively, and group the packaged products. It can continuously receive packaged products, group the received packaged products, and prepare materials for the boxing mechanism.

[0049] 4. The structure of the empty box distribution mechanism is designed so that it can detect whether there is a lack of empty boxes based on the middle-layer photoelectric sensor or the lower-layer photoelectric sensor to drive the box pushing cylinder to pick up empty boxes from the upper-layer empty box roller line. The upper-layer opening and closing mechanism and the middle-layer opening and closing mechanism respectively reserve empty boxes or release empty boxes to continuously supply empty boxes to the box feeding mechanism, thereby ensuring sufficient supply of boxes to the box feeding mechanism.

[0050] 5. The structures of the box feeding mechanism and the box loading positioning mechanism are designed respectively. When the fourth photoelectric sensor of the box feeding mechanism detects that there is a lack of boxes, the box feeding blocker releases the empty boxes, and the box feeding roller line transports the empty boxes to the bottom of the box pushing mechanism to reserve empty boxes for packaging products. When the packaging boxes filled with products by the box loading positioning mechanism are pushed to the transplanting mechanism, the second servo motor of the box pushing mechanism drives the push plate to move the empty boxes to the box loading positioning mechanism to prepare for packaging products, thereby realizing the orderly supply of boxes to the box loading positioning mechanism on demand.

[0051] 6. The structure of the box opening mechanism is designed so that the box cover can be automatically opened from the top of the empty box. The box opening mechanism cooperates with the packing mechanism to load the packaged products from the top of the empty box and ensure that the packaged products are packed neatly. This greatly improves the packing efficiency of the packaged products and the subsequent sealing efficiency, and solves the problem that the existing box opening machine can only pack the empty boxes sideways, and cannot open the empty boxes from the top and cannot load the packaged products from the top of the empty boxes, resulting in uneven packing and low packing efficiency.

[0052] 7. By designing the structure of the transplanting mechanism and coordinating it with the upper empty box roller line, the lower full box roller line, the empty box distribution mechanism and the case packing machine, it is possible to collect and transport the full boxes transmitted by multiple transplanting mechanisms with only one lower full box roller line and to continuously and sufficiently supply boxes to multiple case packing machines with only one upper empty box roller line. It does not need to be equipped with multiple packaging box conveying lines and multiple full box product conveying lines, so as to solve the problems of complex structure, large space occupation and high production cost caused by the current case packing lines on the market that each case packing machine must be equipped with a packaging box conveying line, a carton opener, a packaging product conveying line and a full box product conveying line.

A seventh servo motor 125 is provided on the outside of one of the transplanting chain conveying assemblies 121. The output end of the seventh servo motor 125 is provided with a second reducer 126. The seventh servo motor 125 is connected and installed with the fourth linkage shaft 124 through the second reducer 126. A transplanting sinking cylinder 127 is provided below the other end of the transplanting conveying frame 120. The output end of the transplanting sinking cylinder 127 is rotatably connected to the transplanting conveying frame 120. Two transplanting bearing seats 123 and the transplanting sinking cylinder 127 are respectively installed on the boxing frame 30. One side of the transplanting chain conveying assembly 121 is also provided with a transplanting guide plate 128 that guides the transmission of full boxes. The structural design of the transplanting mechanism 12 realizes the automatic connection between the box loading and positioning mechanism 8 and the lower full box roller line 2, so that it can automatically and efficiently transfer the full boxes to the lower full box roller line 2 for collection and transmission.

[0104] Reference Fig.23 As shown, the upper empty box roller line 1 and the positions corresponding to the empty box delivery mechanisms 4 are respectively provided with forced stop photoelectric sensors 14, box arrival photoelectric sensors 15 and box separation blockers 16. The end of the upper empty box roller line 1 that receives and stores empty boxes is respectively provided with backlog photoelectric sensors 17, box storage photoelectric sensors 18 and box storage blockers 19. The above design enables it to use one upper empty box roller line 1 to continuously and sufficiently supply boxes to multiple case packers 3, which ensures that the case packers 3 can continuously pack boxes efficiently, thereby solving the problem that multiple case packers 3 of the existing case packing line must be equipped with multiple packaging box conveyor lines.

[0105] Specifically, when the upper empty box roller line 1 starts working, the box blocker 19 blocks the front empty box to reserve empty boxes; when the empty boxes are delivered to each empty box distribution mechanism 4, the box blocker 19 releases the empty boxes; when the middle space position and the lower space position of all the empty box distribution mechanisms 4 respectively store empty boxes, the empty box distribution mechanisms 4 do not take empty boxes from the upper empty box roller line 1; when the box arrival photoelectric sensor 15 and the forced stop photoelectric sensor 14 corresponding to any empty box distribution mechanism 4 detect an empty box at the same time, the upper empty box roller line 1 stops conveying empty boxes; when the backlog photoelectric sensor 17 detects an empty box, the delivery of boxes to the upper empty box roller line 1 is stopped.

[0106] Reference Fig.23 As shown, the positions of the lower full-box roller line 2 corresponding to the transplanting mechanism 12 are respectively provided with full-box blockers 20 and full-box transmission photoelectric sensors 21. The above design enables it to use only one lower full-box roller line 2 to collect and transmit full boxes transmitted by multiple transplanting mechanisms 12, and ensure that the lower full-box roller line 2 transmits full boxes smoothly without retention, and the full-box recovery is efficient, thereby solving the problem that multiple case packing machines 3 of the existing case packing line must be equipped with multiple full-box product conveying lines 6.

[0107] Specifically, when the transplanting mechanism 12 needs to transplant full boxes to the lower full box roller line 2, the full box blocker 20 blocks the full boxes transmitted by the lower full box roller line 2. After the lower full box roller line 2 receives the full boxes transplanted by the transplanting mechanism 12 and starts to transmit, the full box blocker 20 releases the full boxes currently blocked by it; when the current full box transmission photoelectric sensor 21 detects that the corresponding position on the lower full box roller line 2 is transmitting a full box, the transplanting mechanism 12 temporarily transplants the full boxes to the lower full box roller line 2. When the full box passes the current full box transmission photoelectric sensor 21, the full box blocker 20 blocks the subsequent full boxes transmitted, and the transplanting mechanism 12 resumes transplanting full boxes to the lower full box roller line 2. After the lower full box roller line 2 receives the full boxes transplanted by the transplanting mechanism 12 and starts to transmit, the full box blocker 20 releases the subsequent full boxes transmitted by the lower full box roller line 2.

[0108] Reference Fig.24 As shown, the box entry blocker 77, the box separation blocker 16, the storage box blocker 19 and the full box blocker 20 all include a blocking cylinder 22 and a box baffle 23. The box baffle 23 is arranged on the output end of the blocking cylinder 22. The blocking cylinder 22 raises the box baffle 23 to block an empty box or a full box.

[0109] Reference Fig.25As shown, the first limit guide assembly 615, the second limit guide assembly 625, the third limit guide assembly 72, the fourth limit guide assembly 74 and the fifth limit guide assembly 87 all include a limit bracket 24, a second cross bar 25 is provided at the upper end of the limit bracket 24, a movable guide plate 26 is provided on one end of the second cross bar 25, and a locking bolt 27 is provided at the upper end of the limit bracket 24. The length of the second cross bar 25 extending from the limit bracket 24 is adjusted to adjust the movable guide plate 26 to limit the box body, and the locking bolt 27 is tightened to fix the second cross bar 25 to prevent the second cross bar 25 from loosening.

[0110] Reference Figures 1 to 25 As shown, the present invention also provides a packing process of an intelligent empty box delivery packing line: the packaged products 13 are conveyed through the product conveyor lines 6 in each packing machine 3, and the weighing conveying mechanism 61 of the product conveyor line 6 can measure packaged products 13 of different lengths by adjusting the distance between the first photoelectric sensor 617 and the second photoelectric sensor 618, and whether the packaged products 13 meet the packing requirements is determined by measuring the length and weight of the packaged products 13. When the packaged products 13 that do not meet the requirements are conveyed from the weighing conveying mechanism 61 to the reject conveyor line 621 of the reject conveyor mechanism 62, the reject cylinder 623 of the reject conveyor mechanism 62 pulls the reject conveyor line 621 to swing downward around the first rotating shaft 622, so that the packaged products 13 that do not meet the requirements are unloaded and rejected through the reject conveyor line 621. When the packaged product 13 that meets the requirements is transferred from the weighing conveying mechanism 61 to the rejecting conveying mechanism 62, the packaged product 13 that meets the requirements is transferred to the injection conveying belt line 6302 of the injection conveying mechanism 63 via the rejection conveying line 621 of the rejection conveying mechanism 62. The injection conveying mechanism 63 can adjust the product conveying direction of the packaged product 13 with the side conveying belt line 6308 as the reference and close to the side conveying belt line 6308. The injection conveying belt line 6302 and the side conveying belt line 6308 cooperate to increase the friction with the packaged product 13, so that the packaged product 13 can be quickly transferred to the dual-servo material sorting mechanism 5, which ensures that the dual-servo material sorting mechanism 5 transfers the packaged product 13 to the right place. The first circulation line 51 and the second circulation line 52 of the dual-servo material sorting mechanism 5 respectively and cyclically receive the packaged products 13 transmitted from the injection conveying mechanism 63, and group and gather the packaged products 13, so that they can continuously receive the packaged products 13, and gather and group the received packaged products 13 to prepare materials for the boxing mechanism 10.

[0111] As the packaged products 13 are being fed and conveyed, the empty boxes are conveyed through the upper empty box roller line 1. When the upper empty box roller line 1 conveys the empty boxes through each empty box distributing mechanism 4, the box pusher 46 of each empty box distributing mechanism 4 pushes the empty boxes from the upper empty box roller line 1 into the upper space of the box drop bracket 40 under the drive of the box pusher cylinder 45. When the upper opening and closing mechanism 47 and the middle opening and closing mechanism 48 release the support for the empty boxes, the empty boxes fall into the lower space of the box drop bracket 40 and are located on the box feeding mechanism 7. The empty boxes are conveyed to the lower part of the box pushing mechanism 9 through the box feeding roller line 71 of the box feeding mechanism 7 to reserve empty boxes for packing the packaged products 13. The pusher plate 90 of the box pushing mechanism 9 can push the empty boxes from the box feeding roller line 71 into the box packing positioning mechanism 8 under the drive of the second servo motor 92, so as to prepare for the box packing operation of the packaged products 13, thereby realizing the orderly supply of boxes to the box packing positioning mechanism 8 on demand. The fifth limiting guide assembly 87 of the packing and positioning mechanism 8 provides a limiting reference for the empty box pushed from the box pushing mechanism 9 and limits the empty box through the box pushing roller 80. At the same time, the first box picking part 113 and the second box picking part 114 of the box picking mechanism 11 respectively pick up the box covers on the two adjacent sides of the two corners on the diagonal line of the empty box to realize automatic opening of the empty box from the top. Then, the suction nozzle 1005 of the packing mechanism 10 sucks the packaged product 13 from the double servo material sorting mechanism 5 and places it in the empty box on the packing and positioning mechanism 8 to automatically pack the packaged product 13. When the empty box is filled with packaged products 13 (referred to as a full box), the box pushing roller 80 of the box positioning mechanism 8 rotates under the drive of the third servo motor 86 to transfer the full box to the two parallel transplanting chain conveying assemblies 121 of the transplanting mechanism 12, and the seventh servo motor 125 of the transplanting mechanism 12 drives the two transplanting chain conveying assemblies 121 to convey the full box to the top of the lower full box roller line 2 through the second reducer 126 and the fourth linkage shaft 124. The transplanting sinking cylinder 127 drives the transplanting conveying frame 120 to swing downward around the second rotating axis 122, and the two transplanting chain conveying assemblies 121 are lowered and lower than the lower full box roller line 2, so that the full box is conveyed to the lower full box roller line 2, and the lower full box roller line 2 realizes the collection and transmission of full boxes transmitted from multiple transplanting mechanisms 12, so that it can realize automatic material unloading and recovery of full boxes.

[0112] Its overall structural design realizes the automatic loading and conveying of empty boxes and packaged products 13 respectively on a distribution line, the automatic length and weight detection of the conveyed packaged products 13, the automatic unloading and rejection of the packaged products 13 that do not meet the detection requirements, the automatic grouping and collection of the packaged products 13 that meet the detection requirements, the automatic storage of empty boxes, the automatic orderly supply of empty boxes according to the detected box shortage status, the automatic positioning of the empty boxes before packing, the automatic unpacking of empty boxes, the automatic filling of empty boxes with packaged products 13, and the automatic collection, conveying and unloading of full boxes filled with packaged products 13 for recycling. It not only realizes the automatic opening of the box cover from the top of the empty box and the automatic loading of packaged products 13 from the top of the empty box without adding a structure for adjusting the swing direction of the empty box, but also does not need to be equipped with multiple package box conveyors in the entire packing line. The invention relates to a packaging line and a plurality of full-box product conveyor lines, which simplifies the structure, reduces the occupied space and reduces the cost, and has the advantages of neat packing, good packing effect, high packing efficiency and high full-box recycling efficiency for the packaged products 13. In addition, it is also suitable for detecting packaged products 13 of different lengths and for opening the box covers of boxes of different sizes, so as to achieve strong versatility and further reduce the production cost. It not only solves the problem that each packing machine on the current packing line on the market must be equipped with a packaging box conveyor line, a carton opener, a packaging product conveyor line and a full-box product conveyor line, which leads to complex structure, large occupied space and high production cost, but also solves the problem that the current carton openers on the market can only pack empty boxes laterally, which leads to uneven packing, low packing efficiency and poor packing effect.

[0113] The above embodiment is only an example of the present invention and is not intended to limit the implementation and scope of rights of the present invention. Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
