Description

Technical Field

[0001] The present invention relates to the field of automated processing, and in particular to an automated packaging system and packaging method for sheet material stacks. Background Art

[0002] Sheet products are often stacked, packaged and transported in the form of stacks. For sheet products in which at least one set of side edges is a straight edge, they are often bundled and packaged with wrapping paper after being stacked into a certain number of stacks to improve the stability of the stacking and improve the efficiency of packaging and transportation. For example, the outer packaging carton of cigarettes exists in the form of printed and die-cut cardboard before being folded into a box. Before transportation, a certain number of cardboards need to be stacked into a stack and bundled with kraft paper tape. At present, the bundling and packaging operations of the stacks are basically completed manually. Due to the large uncertainty of the bundling force and bundling position of each manual bundling operation, there are generally problems such as low packaging efficiency and unstable quality. The production and processing of sheet products have generally been automated, and the bundling and packaging of the stacks has largely limited the improvement of production efficiency.

[0003] The Chinese invention patent application with application publication number CN 111392121A discloses an automatic packaging device for finished cigarette box paperboards, which can automatically complete the operations of neatly feeding cigarette box paperboards, feeding and packing wrapping paper, pasting wrapping paper, etc., and has the advantage of high efficiency. However, the above automatic packaging device still has shortcomings, including: 1. The bundling steps of wrapping paper are feeding wrapping paper into a ring--the cigarette box paperboard is neatly fed into the ring wrapping paper--adjusting the tightness of wrapping paper--cutting wrapping paper. In the above bundling process, how to limit the wrapping paper to a ring shape, how to adjust the tightness of wrapping paper, and the structure and working mode of the stopper are not clearly introduced, and the reliability of the wrapping paper bundling is uncertain; 2. After the wrapping paper is bundled, in the process of the discharging device transferring the material stack to the gluing support, there is a lack of structural design to constrain the wrapping paper, and the tightness of the wrapping paper cannot be guaranteed before gluing, which will affect the reliability of the packaging. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an automatic packaging system and packaging method for sheet material stacks, which can automatically complete the bundling and packaging operations of sheet material stacks and has the advantages of reliable bundling and high efficiency.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an automated packaging system for sheet material stacks, comprising at least: A frame, wherein the frame is provided with a loading station, a paper feeding station, a gluing station and a unloading station; A paper feeding module, wherein the paper feeding module comprises a paper feeding assembly and a paper receiving assembly, wherein the paper feeding assembly comprises a paper feeding bracket and a packaging paper conveying unit; wherein the paper receiving assembly comprises a paper receiving bracket, a pressing unit and a translation driving unit, wherein the pressing unit is arranged on the paper receiving bracket, the paper receiving bracket is arranged opposite to the paper feeding bracket, and the translation driving unit drives the paper receiving bracket to translate relative to the paper feeding bracket; The glue sticking module comprises a glue sticking bracket, a glue feeding unit and a glue sticking assembly. The glue sticking bracket is located at the glue sticking station, the glue feeding unit is located at one side of the glue sticking station, and the glue sticking assembly is located below the glue sticking bracket; the glue sticking assembly is used to take the adhesive tape from the glue feeding unit and transfer and stick it to the material stack placed on the glue sticking bracket; The paper wrapping module comprises a base, on which two groups of material stack clamping arms extending downward are provided, and the lower ends of the material stack clamping arms are provided with a support plate; the two groups of material stack clamping arms are arranged in parallel, and together with the base, they enclose a paper wrapping interval; the base is also provided with a paper wrapping clamping plate and a flipping drive unit, the paper wrapping clamping plate corresponds to the opening side of the paper wrapping interval one by one, and the flipping drive unit drives the paper wrapping clamping plate to flip up and down relative to the base; the free end of the paper wrapping clamping plate is provided with a closing drive member; The transfer module includes a feeding assembly, an intermediate transfer assembly and a discharging assembly. The feeding station is used to transfer the material stack from the loading station to the paper feeding station, the intermediate transfer assembly is used to drive the paper wrapping module to transfer between the paper feeding station and the gluing station, and the discharging assembly is used to transfer the material stack from the gluing station to the unloading station.

[0006] When performing packaging operations, place the stack of materials on the loading station, and the feeding assembly works to transfer the stack of materials to the paper feeding station to complete the feeding operation. When the paper feeding module works, the translation drive unit first drives the paper receiving bracket close to the paper feeding bracket, and the paper feeding assembly feeds the packaging paper until the end of the packaging paper moves to the paper receiving bracket, and the paper receiving bracket constrains the end of the packaging paper. Then the translation drive unit drives the paper receiving bracket to move away from the paper feeding bracket, and the packaging paper conveying unit continues to feed paper. Under the constraint of the paper receiving bracket, the packaging paper maintains a certain tension. Finally, after the paper is fed to a specific length, the paper feeding assembly cuts the packaging paper to complete the feeding operation. On the premise of ensuring that there is no mutual interference, the feeding operation and the paper feeding operation can be performed simultaneously or in sequence. At this time, the packaging paper and the stack of materials are both located at the paper feeding station, and the packaging paper is located above the stack of materials.

[0007] The intermediate transfer module works, driving the paper wrapping module to move to the paper feeding station, the material stack enters the paper wrapping area of ​​the paper wrapping module, the wrapping paper is located between the material stack and the base, and the support plate lifts the material stack from below the material stack. After the paper wrapping module completes the material stack clamping operation, the intermediate transfer assembly drives the paper wrapping module and the material stack to move from the paper feeding station to the gluing station. In the process of separating the material stack and the wrapping paper from the paper feeding station and moving to the gluing station, the paper wrapping clamp flips down and presses the wrapping paper from the side. Finally, the closing drive folds the lower end of the wrapping paper toward the bottom of the material stack to complete the paper wrapping operation.

[0008] After the stack is transferred to the gluing station, the gluing component takes the tape from the gluing unit and sticks it to the joint of the packaging paper on the stack placed on the gluing bracket to complete the gluing operation. Finally, the unloading component transfers the stack with glued material to the unloading station to complete the packaging operation of the stack.

[0009] Compared with existing automatic packaging devices, the automatic packaging system of the present application has the advantages of high automation, high efficiency, reliable bundling, and stable packaging tightness.

The feed conveying line is located between the two lateral clamping plates, and the sorting drive is used to drive the two lateral clamping plates to move relatively closer or farther away.

[0011] The loading conveying unit is used to temporarily store and convey the material stacks. Multiple material stacks can be placed on the loading conveying line at the same time. The feeding conveying unit is used to drive the material stacks to feed the paper feeding station one by one. The feeding transfer unit is used to transfer the material stacks from the loading conveying unit to the feeding conveying unit. During the transfer clamping part transferring the material stack, the two end clamping arms clamp the material stack and align the ends of the material stack at the same time.

[0018] During the transfer of the stack from the paper feeding station to the gluing station, the paper wrapping operation is carried out.

[0031] The loading conveying unit 34 is used to temporarily store and convey the material stacks. Multiple material stacks can be placed on the loading conveying line in sequence at the same time. The feeding conveying unit 33 is used to drive the material stacks to feed the paper feeding station one by one. The feeding transfer unit 35 is used to transfer the material stacks from the loading conveying unit 34 to the feeding conveying unit 33. In the process of transferring the material stack by the transfer clamp, the two end clamping arms clamp the material stack and align the ends of the material stack at the same time. In the process of conveying the material stack by the feeding conveying unit 33, the material stack pauses between the two side clamping plates, and the two side clamping plates are brought together to align the sides of the material stack.

[0032] The intermediate transfer assembly 31 includes a support beam, on which a slider and a first intermediate drive are provided, and the first intermediate drive is used to drive the slider to move along the guide rail. The slider is provided with a support arm and a second intermediate drive, and the second intermediate drive is used to drive the support arm to move up and down relative to the slider, and the paper wrapping module 4 is connected to the support arm. When the stack of materials is transferred from the paper feeding station to the gluing station, the intermediate transfer mechanism lifts the paper wrapping module 4 and the stack of materials into the air, separates them from the paper feeding station, and transfers them to the gluing station in the form of being placed from top to bottom. The transfer method is more direct and efficient, and also facilitates the packaging closure of the lower end of the wrapping paper.

[0033] like Figure 5-Figure 8 As shown, the paper feeding module 2 includes a paper feeding component and a paper receiving component. The paper feeding component includes a paper feeding bracket 22 and a packaging paper conveying unit 21. The packaging paper conveying unit 21 is a prior art and is mainly used to realize the feeding and cutting of packaging paper. Its specific structure and working principle are not described in detail. The paper receiving component includes a paper receiving bracket 23, a pressing unit 25 and a translation drive unit 24. The pressing unit 25 is arranged on the paper receiving bracket 23. The paper receiving bracket 23 is arranged opposite to the paper feeding bracket 22. The translation drive unit 24 drives the paper receiving bracket 23 to translate relative to the paper feeding bracket 22.

[0034] like Figure 5-Figure 8 As shown, specifically, the paper feeding module 2 further includes a lifting adjustment component 28, and the lifting adjustment component 28 is used to drive the paper feeding bracket 22 and the paper receiving bracket 23 to perform lifting movements respectively.

[0035] like Figure 5-Figure 8 As shown, the paper feeding assembly further includes a paper feeding base 27 and a sliding base 26, and the paper receiving bracket 23 is movably connected to the sliding base 26. The translation drive unit 24 is disposed on the paper feeding base 27 and drives the sliding base 26 to translate relative to the paper feeding base 27.

[0036] like Figure 5-Figure 8 As shown, the paper feeding support 22 includes a paper feeding platform 221, the lifting and adjusting assembly 28 drives the paper feeding platform 221 to move up and down, and a pressure roller 222 is provided on the paper feeding platform 221. The paper receiving support 23 includes a paper receiving platform 231, the lifting and adjusting assembly 28 drives the paper receiving platform 231 to move up and down, and the pressing unit 25 is arranged on the paper receiving platform 231. The pressing unit 25 includes a pressing plate and a pressing driving unit. The pressing plate is located above the paper receiving platform 231, and the pressing driving unit drives the pressing plate to move up and down. In order to ensure that the packaging paper reaches the paper receiving platform 231 smoothly, when it is at the upper limit position, the paper receiving platform 231 is lower than the paper feeding platform 221.

[0037] During the feeding of the wrapping paper, the paper feeding bracket 22 and the paper receiving bracket 23 can be adjusted to a higher position to leave enough space for the feeding of the material stack to avoid mutual interference. The paper feeding operation and the material feeding operation can be performed simultaneously to speed up the work rhythm. When the material stack and the wrapping paper are both fed in place, the paper feeding bracket 22 and the paper receiving bracket 23 move downward to a lower position to leave enough space for the paper wrapping module 4 to work with the material stack.

[0038] like Figure 17-Figure 20 As shown, the gluing module 5 includes a gluing bracket 52, a gluing feeding assembly 51 and a gluing assembly 53. The gluing feeding assembly 51 is located on one side of the gluing bracket 52, and the gluing assembly 53 is located below the gluing bracket 52. The gluing bracket 52 is provided with a material stack support position, and the material stack support position is provided with a gluing channel. When performing the gluing operation, the gluing bracket is used to receive the material stack, and the lower end of the packaging paper is stacked on the lower end of the material stack and aligned with the gluing channel.

[0039] like Fig. 20 and Fig.21 As shown, the glue feeding assembly includes a glue feeding bracket 512 and a glue feeding driving member 511. The glue feeding bracket 512 is provided with a tape mounting seat 5122 and a tape guiding channel 5121. The adhesive tape 8 is pre-rolled on the tape mounting seat 5122, and the head of the adhesive tape 8 is pre-placed in the tape guiding channel 5121. The glue feeding bracket 512 is also provided with a detection unit 513 for detecting whether there is adhesive tape on the tape guiding channel 5121.

[0040] like Fig. 20 and Fig.21 As shown, the glue sticking assembly includes a glue sticking execution unit 532, a glue sandwiching unit 533 and a glue cutting unit 531, the glue sticking execution unit 532 is located between the glue sandwiching unit 533 and the glue cutting unit 531, and the glue sandwiching unit 533 is located on the side of the glue sticking execution unit 532 away from the glue feeding assembly, and the glue cutting unit 531 is located on the side of the glue sticking execution unit 532 close to the glue feeding assembly.

[0041] like Fig. 20 and Fig.21 As shown, the glue sticking execution unit 532 includes a glue sticking head 5322 and a feeding drive 5321. The glue sticking head 5322 is located below the glue sticking channel, and the feeding drive 321 drives the glue sticking head 5322 to move up and down. Specifically, the glue sticking head 5322 is a negative pressure adsorption head, which transfers the adhesive tape in the form of negative pressure adsorption, which is stable and reliable.

[0042] like Fig. 20 and Fig.21As shown, the inlet end of the tape guiding channel 5121 corresponds to the tape mounting seat 5122, and the outlet end is arranged toward the glue clamping unit 533, and the glue feeding driving member 511 is used to drive the glue feeding bracket 512 to approach and move away from the glue sticking assembly.

[0043] like Fig. 20 and Fig.21 As shown, the clamping unit 533 includes a clamp 5332 and a clamping drive 5331, and the clamping drive 5331 drives the clamp 5332 to open and close. The clamping unit 533 is used to clamp the head of the tape. When the head of the tape is clamped and limited, the tape as a whole retreats to complete the feeding of the tape. In order to avoid adhesion with the tape, the clamp 5332 is made of Teflon material. Teflon material has good non-stick properties, which can ensure that the tape can be normally fed out by the adhesive head while clamping.

[0044] like Fig. 20 and Fig.21 As shown, the glue cutting unit 531 includes a cutter 5312 and a glue cutting driving member 5311. The cutting edge of the cutter 5312 is set upward, and the glue cutting driving member 5311 drives the cutter 5312 to move up and down. After the glue feeding is completed, the adhesive tape covers the glue sticking head 5322 and also covers the cutter 5312. The cutter 5312 moves upward to cut the adhesive tape.

[0045] When feeding glue, the initial state is as follows Fig. 22 As shown, the glue feeding drive member 511 drives the glue feeding bracket 512 to move toward the glue clamping unit 533, and the glue clamping unit 533 clamps the head of the adhesive tape 8, that is, Fig.23 Then the glue feeding drive 511 drives the glue feeding bracket 512 to retreat and reset, and the corresponding adhesive tape 8 is fed and covers the top of the glue sticking head 5322, and finally the glue cutting unit 531 cuts off the adhesive tape 8, and the glue feeding is completed. Fig.24 The feeding drive unit drives the gluing head 5322 to feed upward, and the gluing head 5322 sticks the adhesive tape 8 to the joint of the wrapping paper to complete the gluing operation.

[0046] like Figure 17-Figure 20 As shown, specifically, the glue sticking bracket 52 includes a paper tightening assembly, and the paper tightening assembly includes a paper tightening driving member 55 and two receiving members 521. The two receiving members 521 are arranged opposite to each other, and the paper tightening driving member 55 is used to drive the two receiving members 521 to move relative to each other. In order to avoid interference between the paper tightening assembly and the support plate 43 in the paper wrapping module 4, each receiving member 521 includes two receiving blocks, and a gap is left between the two receiving blocks. When the paper wrapping module 4 transfers the stack to the glue sticking station, the support plate 43 corresponds to the gap between the two receiving blocks.

[0047] like Figure 17-Figure 20As shown, the gluing module 5 further includes a height adjustment unit 54, which is used to drive the gluing bracket 52 to move up and down. The upper limit position of the gluing bracket 52 is higher than the discharge conveyor line, and the lower limit position is lower than the discharge conveyor line. When the gluing bracket 52 is at the upper limit position, the material stack is separated from the discharge conveyor line, which is convenient for the paper tightening component to work. After the paper tightening is completed, the gluing bracket 52 falls back and the material stack is placed on the discharge conveyor line.

[0048] During the transfer of the stack from the paper feeding station to the gluing station, the paper wrapping operation is performed. Since the stack is supported by the bottom end, the stack tends to deform downward under the action of gravity, which has a certain impact on the tightness of the packaging paper. After the stack is transferred to the gluing station, the packaging paper is placed on the two receiving parts 521 of the paper tightening assembly, and the paper tightening driving part 55 drives the two receiving parts 521 to move closer to each other. Since the packaging paper is pressed on the receiving parts 521 by the gravity of the stack, the two lower ends of the packaging paper will also move synchronously, which plays a role of further tightening. After the subsequent gluing, the packaging tightness of the stack is guaranteed.

[0049] like Figure 9-13 As shown, the paper wrapping module 4 includes a base 41, on which two groups of stack clamping arms 42 extending downward are provided, and a support plate 43 is provided at the lower end of the stack clamping arms 42. The two groups of stack clamping arms 42 are arranged in parallel, and together with the base 41, they enclose a paper wrapping section. The base 41 includes a pre-pressing unit, which is located in the paper wrapping section and has an action end arranged downward. The pre-pressing unit always provides a pre-tightening force between the wrapping paper and the stack, which can improve the stability between the stack and the wrapping paper, thereby ensuring the reliability of the paper wrapping. The base 41 is also provided with a paper wrapping clamping plate 44 and a flipping drive unit 45, and the paper wrapping clamping plate 44 corresponds to the opening side of the paper wrapping section one by one, and the flipping drive unit 45 drives the paper wrapping clamping plate 44 to flip up and down relative to the base 41. The free end of the paper wrapping clamping plate 44 is provided with a closing drive member.

[0050] like Figure 9-13 As shown, the stack clamping arm 42 is provided with a longitudinal adjustment drive member 47 and a transverse adjustment drive member 46. The longitudinal adjustment drive member 47 is used to drive the support plate 43 to move in the vertical direction, and the transverse adjustment drive member 46 is used to drive the support plate 43 to move in the horizontal direction.

[0051] When the paper wrapping module 4 clamps the stack of materials, the driving member 47 is first adjusted longitudinally to drive the support plate 43 to move downward, increasing the distance between the support plate 43 and the base 41, and the driving member 46 is adjusted transversely to drive the support plate 43 to move outward, leaving enough space for the stack of materials to enter between the two stack of materials clamping arms 42. The intermediate transfer assembly 31 drives the paper wrapping module 4 to move from top to bottom in the paper feeding station, and the wrapping paper and the stack of materials enter the paper wrapping interval in turn, driving the wrapping paper to be located above the stack of materials. When the wrapping paper and the stack of materials contact the base 41, it is considered that the stack of materials has successfully entered the paper wrapping interval. At this time, the support plate 43 is lower in height than the bottom surface of the stack of materials, and the driving member 46 is adjusted transversely to drive the support plate 43 to move horizontally inward to enter the bottom of the stack of materials. Then, the driving member 47 is adjusted longitudinally to drive the support plate 43 to move upward to lift the stack of materials, and press the stack of materials together with the base 41 to complete the stack of materials clamping operation.

[0052] like Figure 9-13 As shown, the paper wrapping clamp 44 is provided with a rotating shaft, and the rotating shaft is rotatably connected with the base 41. The flip driving unit 45 includes a flip slider 452 and a flip driving member 451 located at one end of the base 41, and the flip driving member 451 drives the flip slider 452 to move up and down. The flip driving unit 45 also includes a connecting rod 453 corresponding to the paper wrapping clamp 44 one by one, one end of the connecting rod 453 is connected to the rotating shaft and rotates synchronously, and the other end is provided with a long strip groove. Two driving arms are fixedly provided on the flip slider 452, and the driving arms correspond to the connecting rod 453 one by one and are slidably connected with the long strip groove. When the flip slider 452 moves up and down, the connecting rod 453, the rotating shaft and the paper wrapping clamp 44 rotate synchronously relative to the base 41.

[0053] like Figure 9-13 As shown, the closing drive member includes a closing plate 48 and a closing power unit 49. The closing plate 48 is arranged perpendicular to the paper wrapping clamp 44. The closing power unit 49 is used to drive the closing plate 48 to translate perpendicular to the paper wrapping clamp 44 or to flip relative to the paper wrapping clamp 44. The closing drive unit drives the closing plate 48 to move relative to the paper wrapping clamp 44 to complete the folding operation of the lower end of the packaging paper.

[0054] When performing packaging operations, the stack 6 is placed on the loading station, and the feeding assembly works to transfer the stack 6 to the paper feeding station to complete the feeding operation. Figure 6 As shown, first, the translation driving unit 24 drives the paper receiving bracket 23 to approach the paper feeding bracket 22, and the paper feeding assembly feeds the packaging paper 7 until the end of the packaging paper 7 moves to the paper receiving bracket 23, and the paper receiving bracket 23 constrains the end of the packaging paper 7, as shown in FIG. Figure 8As shown, the translation drive unit 24 then drives the paper receiving bracket 23 to move away from the paper feeding bracket 22, the packaging paper conveying unit 21 continues to feed paper, and under the constraint of the paper receiving bracket 23, the packaging paper 7 maintains a certain tension, and finally after the paper is fed to a specific length, the paper feeding assembly cuts the packaging paper 7 to complete the paper feeding operation. Under the premise of ensuring that there is no mutual interference, the feeding operation and the paper feeding operation can be performed simultaneously or in sequence. At this time, the packaging paper 7 and the material stack 6 are both located at the paper feeding station, and the packaging paper is located above the material stack.

[0055] The intermediate transfer module works, driving the paper wrapping module 4 to move to the paper feeding station, and the stack of materials enters the paper wrapping area of ​​the paper wrapping module 4. The wrapping paper is located between the stack of materials and the base 41. The support plate 43 lifts the stack of materials from below, and the pre-pressing unit applies a downward pressing force to the stack of materials. After the paper wrapping module 4 completes the clamping operation of the stack of materials, the intermediate transfer assembly 31 drives the paper wrapping module 4 and the stack of materials to move from the paper feeding station to the gluing station. In the process of the stack of materials and the wrapping paper separating from the paper feeding station and moving to the gluing station, the paper wrapping clamp 44 flips downward and presses the wrapping paper from the side. Finally, the closing drive folds the lower end of the wrapping paper toward the bottom of the stack of materials to complete the paper wrapping operation, i.e. Figure 14-16 The process shown.

[0056] After the stack is transferred to the gluing station, the gluing assembly 53 takes the adhesive tape 8 from the gluing unit 51 and sticks it to the joint of the packaging paper 7 placed on the stack on the gluing bracket 52 to complete the gluing operation. Finally, the discharging assembly 32 works to transfer the stack 6 with glued material to the unloading station to complete the packaging operation of the stack 6.
