Description

Technical Field

[0001] This invention relates to the field of hygiene products, and more particularly to an automatic diaper processing device. Background Technology

[0002] Diapers are disposable products, commonly used daily necessities for infants and also a type of adult care product. Diapers are typically composed of a breathable outer layer, an absorbent core layer, and a waterproof backing layer. The edges of the breathable outer layer and the backing layer extend beyond the absorbent core layer, meaning the absorbent core layer is smaller than the outer and backing layers. In the production process, the three layers are usually cut to a predetermined size, then the outer and backing layers are sequentially coated with adhesive, and finally the waterproof backing layer, absorbent core layer, and breathable outer layer are stacked and pressed together. Alternatively, the absorbent core layer can be cut into individual sheets on one machine and then pressed together on another machine: first, adhesive is applied to the top surface of the waterproof backing layer; then, the absorbent core layer sheet is placed on the waterproof backing layer manually or by a robotic arm and conveyed forward; next, adhesive is applied to the breathable outer layer, and its bottom surface is attached to the absorbent core layer; finally, they are pressed together and then cut. However, regardless of the method used, there are problems such as numerous steps, the need for more equipment or complex equipment structures, large space requirements, and low work efficiency.

The middle layer material is transferred via the middle conveying layer and the first clamping device to the cutting device for cutting. The flipping device sprays adhesive onto the bottom surface of the upper layer and the top surface of the lower layer, then flips the cut product and attaches it to the top surface of the lower layer, pressing it together with the upper layer through the material passage and into the pressing device. The second clamping device pulls the pressed composite layer to the slitting device for cutting and transfers the cut product to the conveying device for subsequent processing.

[0005] Furthermore, the left rotating bracket is also provided with a glue supply channel connected to the nozzle, and each end of the central frame is provided with a hollow connecting pipe, which is equipped with a glue supply pipe and connected to the glue supply channel.

[0006] Furthermore, the lower conveying assembly also includes a lower roller located in front of the lower guide roller, and a guide support plate is also provided below the lower guide roller and the lower roller.

[0007] Furthermore, the bracket is provided with a three-beam assembly, the beam assembly including two opposing beams, the top surface of the beams being provided with a limiting slot, the limiting slot being provided with a fastener, the fastener being installed on the beams by fasteners.

By incorporating a flipping device to pick up, insert, and paste the absorbent core layer, and simultaneously spray adhesive on the bottom surface of the breathable surface layer and the top of the waterproof bottom layer, not only are production steps reduced, work efficiency improved, but the number of equipment required is also reduced. The overall structural layout of the present invention is reasonable, highly practical, and has significant potential for widespread application. Attached Figure Description

[0029] like Figures 1 to 8 As shown, this invention provides an automatic diaper processing device. The diaper includes a surface breathable layer, an absorbent core layer, and a waterproof bottom layer arranged sequentially from top to bottom. The automatic diaper processing device is used to press the surface breathable layer, absorbent core layer, and waterproof bottom layer of the diaper into shape in one step and then cut them. The automatic diaper processing device includes a base 100 and, from front to back, a feeding device 10, a cutting device 20, a flipping device 30, a pressing device 40, a first clamping device 50, a cutting device 60, a second clamping device 80, and a conveying device 70, all sequentially mounted on the base 100.

[0030] The feeding device 10 includes a support 11, three feeding assemblies 12 mounted on the support 11, and a conveying assembly 13. The support 11 has three sets of crossbeams, each set including two opposing crossbeams 111. Each crossbeam 111 has a limiting groove 112 on its top surface, with the groove gradually increasing in diameter from the bottom towards the locking position to facilitate insertion. A fastener 113 is provided on one side of the limiting groove 112, and is mounted on the crossbeam 111 by a fastener 114. The fastener 113 can rotate along the fastener 114. The three feeding assemblies 12 are arranged side-by-side at upper, middle, and lower intervals. Each feeding assembly 12 includes a mother roller 121 and two drive rollers 122. The two drive rollers 122 are arranged horizontally side-by-side, with the mother roller 121 located on the outermost side and positioned lower than the two drive rollers 122.

[0031] Both ends of the drive roller 122 and the mother roller 121 are respectively mounted on the corresponding crossbeams 111 on the bracket 11. During installation, both ends of the mother roller 121 are respectively inserted into the two limiting slots 112, and then the fastener 114 is rotated to loosen it. The buckle 113 is rotated along the fastener 114 to the top of the limiting slot 112, and then the fastener 114 is locked to limit the mother roller 121 within the limiting slot. The mother roller 121 extends to the outer surface of the limiting slot 112 and is equipped with a bearing, so that the mother roller 121 can still rotate after being limited within the limiting slot 112. In this embodiment, the upper, middle and lower three sets of feeding components 12 are used to feed the surface breathable layer, the absorbent core layer and the waterproof bottom layer, respectively, and the three mother rollers 121 are respectively equipped with rolled surface breathable layer, absorbent core layer and waterproof bottom layer. In addition, the bottom of the bracket 11 may be provided with a lockable roller 115; the roll material can be installed on the spare bracket 11 first, and when it is necessary to change the roll, the spare bracket 11 can be pushed over to replace the original bracket 11, thereby reducing the time spent when changing the roll.

[0032] The conveying assembly 13 includes an upper conveying assembly, a middle conveying assembly, and a lower conveying assembly. The upper conveying assembly includes an upper roller 131 and an upper guide roller 132. The upper roller 131 is located behind the uppermost feeding assembly 12 in the conveying direction and is arranged side by side. The upper guide roller 132 is located behind and below the upper roller 131. The middle conveying assembly includes a middle conveying roller 133, which is located behind the middle feeding assembly 12 in the conveying direction. The lower conveying assembly includes a lower roller 134 and a lower guide roller 135. The lower roller 134 is located behind the lowermost feeding assembly 12 in the conveying direction and is arranged side by side. The lower guide roller 135 is located above and behind the lower roller 134, and the upper guide roller 132 and the lower guide roller 135 are arranged vertically opposite each other, forming a material passage between the upper guide roller 132 and the lower guide roller 135. The height of this material passage is less than or equal to the composite thickness of the surface breathable layer, the absorbent core layer, and the waterproof underlayer. In addition, a guide support plate 136 is provided behind the lower guide roller 135 and the lower roller 134. There is a very small gap between the guide support plate 136 and the outer surface of the waterproof underlayer between the lower guide roller 135 and the lower roller 134, so that it can provide support when the absorbent core layer is applied without affecting the conveying.

[0033] The cutting device 20 is located behind the middle conveyor roller 133, and the first clamping device 50 is located behind the cutting device 20. The cutting device 20 includes a lower positioning block 21 and an upper cutting assembly. The upper cutting assembly includes a positioning block 22 and a cutting block 23 located below the positioning block 22. The cutting block 23 has several through holes extending vertically. The bottom surface of the positioning block 22 has several downwardly extending positioning protrusions 24, which are fitted into the through holes, and the length of the positioning protrusions 24 is greater than the depth of the through holes. A cutting blade 25 is provided on the bottom surface of the cutting block 23 between two adjacent through holes. In addition, a top material block 26 that can move vertically is also provided in the middle of the lower positioning block 21. During operation, the positioning block 22 is driven by a cylinder to move downward, so that the bottom end face of the positioning protrusion 24 presses against the top surface of the absorbent core layer to fix the absorbent core layer. Then, the cutting block 23 is driven to move downward to cut the absorbent core layer. The cutting tool 25 cuts the absorbent core layer horizontally and evenly into a row of several pieces. After cutting, the top material block 26 lifts the individual absorbent chips upward to facilitate clamping.

[0034] The base 100 has outer guide rails 71 and inner guide rails 72 on both sides of the first clamping device 50. The first clamping device 50 includes a mounting frame 51 and several grippers 52 mounted on the mounting frame. Both ends of the mounting frame 51 are mounted on the inner guide rails 72 and can move back and forth along the inner guide rails 72. A moving groove 53 is provided on the side of the mounting frame 51. The grippers 52 are mounted in the moving groove 53 and can be adjusted in position to suit the processing of different models of products. During operation, the first clamping device 50 moves along the inner guide rail 72 toward the middle conveyor roller 133. At this time, the lower positioning block 21 and the cutting block 23 are in an open state. The first clamping device 50 enters the cutting device 20 and pulls the absorbent core layer into the cutting device 20 so that it completely covers the effective processing area of ​​the cutting device 20. The stretching length can be controlled by a program so that the stretching length of the first clamping device 50 reaches the required position. Then the cutting device 20 cuts the absorbent core layer. In this embodiment, the cutting device 20 directly and uniformly cuts the absorbent core layer into several ends, and therefore has a horizontal cutter 211 and a vertical cutter 212 as shown in the figure.

[0035] The flipping device 30 includes a movable frame 31 and a spraying device 32 and an adsorption device 33 mounted on the movable frame 31. Both ends of the movable frame 31 are mounted on an outer guide rail 71 and can move along the outer guide rail 71. The movable frame 31 includes two uprights 311 and a central frame, a left rotating frame 312, and a right rotating frame 313 mounted on the two uprights 311. The left rotating frame 312 and the right rotating frame 313 are respectively located on the left and right sides of the central frame. Each upright 311 has a mounting part (not shown) at its bottom end, which is mounted on an inner guide rail 72. A guide groove extending vertically is provided on the inner surface of the upright 311. The inner end of the mounting part can move vertically relative to the guide groove for position adjustment. Specifically, the bottom end of the upright 311 is connected to a drive cylinder, which is mounted on a base 100 and can drive the upright 311 to move up and down. The central frame can rotate 360° relative to the two columns 311.

[0036] The glue spraying device 32 is mounted on the left rotating frame 312. The glue spraying device 32 includes a plurality of nozzles 321, which are evenly distributed on the upper and lower surfaces of the left rotating frame 312. Furthermore, the left rotating frame 312 is provided with a glue supply channel (not shown) for supplying glue to the nozzles 321. A hollow connecting pipe is provided at each end of the central frame. A bearing is fitted over the upper connecting pipe and mounted on the column 311, allowing the central frame to rotate relative to the column 311. A glue supply pipe 322 is installed inside the hollow connecting pipe and connected to the glue supply channel.

[0037] The adsorption device 33 is mounted on the right rotating frame 313. The adsorption device 33 includes several vacuum nozzles 331, which are located on the top surface of the right rotating frame 313. Thus, when the flipping device 30 rotates to the left, the vacuum nozzles 331 are below the right rotating frame 313, facilitating the absorption of the core layer. In this embodiment, the right rotating frame 313 includes several support rods, and the vacuum nozzles 331 are mounted on these support rods. A sliding groove is provided on the outer surface of the central frame, and the position of the support rod within the groove can be adjusted as needed. After adjustment, it can be locked using fasteners (screws, bolts, etc.). The pressing device 40 includes several upper pressure rollers 41 and lower pressure rollers 42, which are arranged vertically opposite each other, forming a material passage between them. The material passage gradually narrows from front to back.

[0038] The slitting device 60 includes an upper mold 61, a lower mold 62, and a slitting cutter 615. The upper mold 61 has a structure basically the same as the upper cutting assembly, including a plurality of slitting positioning blocks 611 and slitting blocks 612 disposed between the slitting positioning blocks 611. The slitting cutter 615 is disposed on the bottom surface of the slitting block 612. The bottom surface of the slitting positioning block 611 is provided with a plurality of protrusions, including an outer protrusion 613 and an inner protrusion 614. The slitting cutter 615 is disposed between the outer protrusion 613 and the inner protrusion 614. In this embodiment, the bottom surface of the inner protrusion 614 is also provided with an upper groove, and the top surface of the lower mold 62 is provided with a lower groove. The upper groove and the lower groove are arranged vertically opposite each other, and the combination of the upper groove and the lower groove forms an accommodating space corresponding to the accommodating absorbent core layer. In addition, a lifting block 621 is provided at the bottom of the lower groove. The lifting block 621 is connected to a drive cylinder, which can drive the lifting block 621 to move upward to push out the cut product. Furthermore, a dust suction device (not shown) is provided on the outside of both the slitting device 60 and the cutting device 20 to suck away the waste generated during cutting.

[0039] During processing, the inner protrusion 614 is driven downward by a cylinder to clamp the composite diaper into the cutting device 60, and the absorbent core layer is housed within the housing space. This position can be determined by controlling the length of the composite layer within the cutting device 60 through program design, thereby achieving accurate positioning. Alternatively, conventional CCD monitoring and alignment can also be used. The cutting tool 615 is driven downward by a cylinder to cut the composite layer positioned by the inner protrusion 614, the outer protrusion 613, and the lower mold 62.

[0040] The second clamping device 80 is disposed between the slitting device 60 and the pressing device 40, and its structure is the same as that of the first clamping device 50. Slide rails are provided on the base 100 at both ends of the second clamping device 80, allowing it to move along these rails to approach or move away from the pressing device 40 and the slitting device 60. In this embodiment, the conveying device 70 is a conveyor belt, and the second clamping device 80 is disposed above it. The second clamping device 80 can clamp and pull the composite layer on the pressing device 40 to the slitting device 60 for secondary positioning and slitting, and then transfer the slit product to the conveying device 70.

[0041] During operation, the upper, middle, and lower feeding components 12 respectively feed the surface breathable layer, absorbent core layer, and waterproof underlayer roll material, and then convey them through the upper conveying component, middle conveying component, and lower conveying component. The upper conveying component conveys the surface breathable layer into the material passage formed by the upper guide roller 132 and the lower guide roller 135, while the middle conveying component sends the absorbent core layer to the middle conveying roller 133. The first clamping device 50 moves towards the middle conveying component and clamps the end of the absorbent core layer, pulling it backward onto the lower positioning block 21 of the cutting device 20, and then returns to its original position. The upper cutting block 23 cuts the absorbent core layer in the end area into several absorbent core layer sheets. The top material block 26 lifts the absorbent core layer sheets, and the first clamping device 50 moves the sheets forward to clamp them below the left rotating frame 312.

[0042] The flipping device 30 is horizontally positioned and moves a certain distance toward the pressing device 40, bringing the adhesive spraying device 32 closer to the waterproof substrate and the surface breathable layer for easier adhesive spraying. After spraying, the flipping device 30 returns to its original position and rotates downwards until it is above the absorbent core layer sheet at the position of the adsorption device 33. The adsorption device 33 picks up the absorbent core layer sheet and rotates it forward and upwards to the position of the guide support plate 136, attaching the absorbent core layer sheet to the waterproof substrate on the front side of the guide support plate 136 and pressing it forward moderately to make the adhesion more secure.

[0043] The upper guide roller 132 and lower guide roller 135 start to convey forward. When the absorbent core layer, which is attached to the upper surface of the waterproof bottom layer, is conveyed between the upper guide roller 132 and lower guide roller 135, the surface breathable layer adheres downward to the absorbent core layer. It is then conveyed to the pressing device 40 for pressing, making the adhesion between the three layers more stable. After pressing, the clamping device 50 at the slitting device 60 moves forward to the rear of the pressing device 40 to clamp and pull the pressed composite layer onto the slitting device 60 for cutting. The lifting block 621 lifts the cut product upward, and the clamping device 50 transfers the product from the lifting block 621 to the conveying device 70. The conveying device 70 then transfers the product to the next processing step.

[0044] In summary, the automatic diaper processing device of the present invention integrates the conveying and spraying of the breathable surface layer, the cutting and placing of the absorbent core layer, and the conveying and spraying of the waterproof bottom layer into one device. It can achieve the spraying of adhesive for the breathable surface layer and the waterproof bottom layer in one operation, without the need for separate equipment to cut the absorbent core layer. A pressing device is used to press the composite layers together, and the thinner breathable surface layer and waterproof bottom layer are further pressed together on the cutting device 60, avoiding the problem of incomplete pressing of thin layers due to the thickness of the absorbent core layer. By setting up a flipping device 30 to pick up, insert, and paste the absorbent core layer, and simultaneously spray adhesive on the bottom surface of the breathable surface layer and the top of the waterproof bottom layer, not only are production steps reduced, work efficiency improved, but the number of equipment required is also reduced. The overall structural layout of the present invention is reasonable, highly practical, and has strong promotional value.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
