Description

Technical Field

[0001] The invention relates to the technical field of sanitary napkin production, in particular to a double-station material sorting mechanism for sanitary napkins. Background Art

[0002] Sanitary napkins are disposable sanitary products designed for women during their menstrual period, mainly used to absorb blood flowing out during menstruation. It is usually made of multiple layers of materials, including the innermost absorbent core, the middle protective layer, and the outermost leak-proof layer. The absorbent core is usually made of a mixture of high molecular absorbent resin (SAP) and wood pulp, which can quickly absorb and lock liquids and keep the surface dry. The protective layer is used to prevent liquid reflux and is usually made of breathable non-woven fabric materials to increase comfort. The outer layer is usually made of waterproof materials, such as polyethylene film, to prevent blood leakage. Sanitary napkins come in different shapes and sizes, including daily use, night use, extended type and ultra-thin type, to meet the needs of different time periods and different flow rates. The sanitary napkin packaging machine is a highly automated equipment specially designed for the packaging process of sanitary napkins. It usually includes the following main parts and functions: the conveying system automatically transports the formed sanitary napkins on the production line to the packaging position to ensure the orderly and efficient transportation of the products; the packaging material supply provides materials for packaging, such as packaging film, packaging paper or packaging bags, to ensure the continuous supply of packaging materials; the sealing and cutting system heat-seals or cold-seals the packaging materials and accurately cuts them into the required packaging size to ensure the sealing of the seal and the neatness of the cutting; the product positioning system uses sensors and mechanical devices to ensure that each sanitary napkin can be precisely aligned when entering the packaging area to ensure the neatness and beauty of the packaging; the final packaging system puts the sanitary napkins into pre-prepared packaging bags or boxes, and performs the final sealing and marking to ensure the integrity and identifiability of the product.

[0003] In the current sanitary napkin production environment, when customers need to combine two different products, such as sanitary napkins or menstrual pants (product A and product B) in one bag, the automation function of the existing packaging machine seems to be unable to cope with it.

[0018] See Figure 1. Figure 2 As shown, it includes a material sorting frame mechanism 1, a material sorting lifting mechanism 2, a material sorting active shaft 1 3, a material sorting active shaft 2 4, a material sorting tensioning mechanism 5, a support plate 7 fixed on the main machine, a vertical plate 6 installed on the support plate 7, connected in the middle by a cross beam 8, a guide rail mounting plate 9 installed on the cross beam 8, a chain guide rail 10 fixed on the guide rail mounting plate 9, and left and right baffles 11 fixed on the vertical plate 6. This mechanism mainly plays a supporting role.

[0019] See Figure 1. Figure 3 As shown, the lifting vertical plate 13 is fixed on the guide rail 12, four optical axes 15 are installed on the distance plate 14, and a product receiving plate 16 is provided on the top of the optical axis 15. Side clamping cylinders 18 are installed on the lifting left and right plates 17, and the side clamping plates 19 are fixed on the side clamping cylinders 18. This mechanism is used to clamp the product and move it upward.

[0020] See Figure 1. Figure 4 As shown, a synchronous wheel 21, an electromagnetic clutch 22, an electromagnetic clutch fixing plate 23, a sprocket 24, a sprocket 25, a sprocket 3 26, a sprocket 4 27 and a bearing 28 are installed on the driving shaft 20. The mechanism is mainly used to drive the first group of levers to move. When the electromagnetic clutch 22 is in a power-off state, the relative position between the sprocket 25 and the sprocket 3 26 can be adjusted. When the electromagnetic clutch 22 is in a power-on state, the sprocket 25 and the sprocket 3 26 rotate together with the driving shaft 20.

[0021] See Figure 1. Figure 5 As shown, a synchronous wheel 1 21, an electromagnetic clutch 22, an electromagnetic clutch fixing plate 2 29, a sprocket 3 26, and a sprocket 4 27 are installed on the driving shaft 2 28. The mechanism is mainly used to drive the second group of shifting rods to move. When the electromagnetic clutch 22 is in a power-off state, the relative position between the sprocket 3 26 and the first group of shifting rods can be adjusted. When the electromagnetic clutch 22 is in a power-on state, the first group of shifting rods and the second group of shifting rods rotate together.

[0022] See Figure 1. Figure 6 As shown, the connecting and fixing plate 30 is installed on the left and right vertical plates 6, the adjusting plate 31 is connected to the connecting and fixing plate 30, four sprockets 27 are installed on the tensioning shaft 32, and the tensioning shaft 32 is installed on the reinforcement plates 33 on both sides. This mechanism is mainly used for tensioning the first group of shifting rods and the second group of shifting rods together.

[0023] See Figure 1. Figure 8 As shown, the sprocket can rotate around the fixed shaft 36 under the action of the spring 37, wherein the fixed shaft is fixed on the tensioning block 35. This mechanism is mainly used to compensate for the expansion and contraction of the chain itself, thereby playing a tensioning role for the entire chain.

[0024] See Figure 1. Figure 7 As shown, the servo motor 39 is started, and the two synchronous wheels 21 are driven to rotate through the belt 44, thereby transmitting power to the driving shaft 20 and the driving shaft 28 to achieve the purpose. Similarly, when the material lifting mechanism 2 needs to move up and down, the servo motor 40 is started, and the synchronous wheel 43 is driven to rotate through the belt 42, thereby playing a lifting and lowering role.

[0025] Specifically, servo motor 1 39 and servo motor 2 40 control the material handling active shaft 1 3 and material handling active shaft 2 4, as well as the up and down movement of the material handling lifting mechanism 2. The high precision and fast response characteristics of the servo motor ensure that the equipment can remain stable and accurate during high-speed operation. The front ends of the active shaft 1 20 and the active shaft 2 28 are fixedly sleeved with a synchronous wheel 1 21, and an electromagnetic clutch 22 is fixedly sleeved through an electromagnetic clutch fixing plate 1 23 and an electromagnetic clutch fixing plate 2 29. The electromagnetic clutch 22 can be powered on or off to achieve flexible adjustment between sprocket 2 25 and sprocket 3 26. This design enables the equipment to quickly respond to different product requirements during the feeding process without stopping or complicated manual operations. Two lifting vertical plates 13 are fixed on the guide rail 12, and four optical axes 15 are installed on the distance plate 14. There is a product receiving plate 16 on the top of the optical axis 15 for receiving and transferring products. The side clamping cylinder 18 is installed on the lifting left and right plates 17, and the side clamping plate 19 is fixed on the side clamping cylinder 18 to clamp the product and move it upward. This design ensures the stability and accuracy of different products during the transmission process. The electromagnetic clutch 22 can flexibly adjust the relative position between the sprocket 25 and the sprocket 3 26 to adapt to the size and feeding requirements of different products. When the electromagnetic clutch 22 is energized, the sprocket rotates with the driving shaft 1 20; when the power is off, the sprocket position can be adjusted separately. This flexible adjustment method greatly improves the adaptability and production flexibility of the equipment. A plurality of vertical plates 6 are fixedly arranged on the outer sides of the two support plates 7, and the upper ends of the front vertical plates 6 and the rear vertical plates 6 are fixedly arranged with left and right baffles 11, and the two support plates 7 are fixedly connected by a crossbeam 8. A guide rail mounting plate 9 is fixedly arranged on the upper end of the crossbeam 8, and a chain guide 10 is fixedly arranged on the upper end of the guide rail mounting plate 9. This structural design provides a stable support, making the entire mechanism more compact and reducing the floor space. Synchronous wheel 1 21 and synchronous wheel 2 43 transmit the power of the servo motor to the driving shaft and the lifting mechanism through belt 1 42 and belt 2 44, ensuring the high efficiency and reliability of the transmission. The guide seat 41 is fixed on the belt 1 42 and connected to the guide rail 12, ensuring the smooth operation of the lifting mechanism. Two adjustment plates 31 are fixedly arranged between the two connecting fixed plates 30, and reinforcement plates 33 are fixedly arranged on the opposite sides of the adjustment plates 31. The tensioning shaft 32 is installed between the reinforcement plates 33 on both sides, and the tensioning blocks 35 at the front and rear ends are fixedly connected to the winding shaft 36, and the lower end of the winding shaft 36 is fixedly arranged with a spring 37. The tensioning mechanism automatically compensates for the expansion and contraction of the chain through the tension of the spring 37, ensuring that the entire chain is always in a tensioned state, thereby improving the transmission efficiency and reliability of the equipment.

[0026] The mechanism is installed at the front end of the packaging machine for sanitary napkins or menstrual pants. The servo motor 1 39 and servo motor 2 40 at the front end of the equipment frame 38 drive the synchronous wheel and the synchronous belt to transmit power to the material handling active shaft 1 3 and the material handling active shaft 2 4, thereby driving the sprocket and the lever mechanism to operate. After product A comes out of the main machine, it is pushed into the sanitary napkin packaging machine by the right pusher. After product B comes out of the main machine, it is pushed into the sanitary napkin packaging machine by the left pusher. Different products enter different levers. The lever spacing can be adjusted by the electromagnetic clutch 22. The operator only needs to change the parameters to achieve the change of different products without complicated offline adjustment operations. The design of the side clamp cylinder 18 and the side clamp plate 19 can position and clamp the product before it enters the lever. The side clamp cylinder 18 is installed at the upper end of the lifting left and right plates 17, and the side clamp plate 19 is fixedly set at the opposite end of the side clamp cylinder 18 to ensure that the product will not be offset or misplaced during the transmission process. The precision and consistency of the product during feeding and transmission are ensured by precision parts such as sprockets, chains, guide rails 12, optical axes 15, and product receiving plates 16. Sprocket 1 24, sprocket 2 25, sprocket 3 26, and sprocket 4 27 are fixedly mounted on the driven shaft 34, the driving shaft 1 20, the driving shaft 2 28, and the tensioning shaft 32, respectively, and connected by chains to achieve stable power transmission. Thus, the automatic feeding of the two products A / B is realized.

[0027] Different products enter different levers, and the lever spacing can be adjusted by the electromagnetic clutch 22. The front ends of the driving shaft 1 20 and the driving shaft 2 28 are fixedly sleeved with a synchronous wheel 1 21, and the electromagnetic clutch 22 is fixedly sleeved through the electromagnetic clutch 22 fixing plate 1 and the electromagnetic clutch fixing plate 2 29. The electromagnetic clutch 22 can be powered on or off to achieve flexible adjustment between the sprocket 2 25 and the sprocket 3 26. This design enables the equipment to quickly respond to different product requirements during the feeding process without stopping or complicated manual operations.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
