Automatic folding and stacking method for water-washed wrinkled abdominal pads

Abstract

The automatic folding and stacking method for washed wrinkled abdominal pads comprises the following steps: The washed wrinkled abdominal pad material is stacked on a storage plate. An operator approaches the station and sequentially feeds the material onto the conveyor belt, securing the four corners of the pad with positioning pins. A motor operates intermittently, utilizing the characteristics of a servo motor, causing the material to sequentially enter the gripping station. Automatic folding occurs, folding the material twice more until it is fully folded. A second servo robot operates, moving a pusher plate laterally to move the folded pad for unloading. The robot then moves back to its initial position, completing one cycle of folding and stacking. Repeating steps one through five allows for continuous folding and stacking of washed wrinkled abdominal pad material. This invention features high intelligence, enabling automatic and rapid folding and stacking of washed wrinkled abdominal pads, significantly reducing manpower consumption and greatly improving processing efficiency.

Description

[0001] This invention is a divisional application of "Automatic folding and stacking device for washing wrinkled abdominal pads and its usage method" (application number: 2022116208413; application date: 2022-12-16). Technical Field

[0002] This invention relates to the field of production and processing technology of washable wrinkled abdominal pads, and in particular to an automatic folding and stacking method for washable wrinkled abdominal pads. Background Technology

[0003] Medical abdominal pads are medical consumables used to apply to wounds, primarily made of non-woven fabric and cotton. They typically need to be non-adhesive to the wound, have strong absorbency, and cause no skin irritation, providing comprehensive wound protection and reducing the chance of contamination. Unlike traditional cotton pads, they offer a significant leap in both absorbency speed and capacity, mainly due to their unique multi-layered structure: a double-layered non-woven fabric surface, a high-quality cellulose inner layer, and a highly absorbent cellulose fiber core. In modern industrial production, after the abdominal pads are manufactured through multi-layer stitching, they often require manual folding, compaction, and stacking before being transported to the packaging process. This process not only consumes a large amount of manual labor for folding, compaction, stacking, and transport but also requires reloading and replenishing materials when changing processing equipment, resulting in low automation and low processing efficiency. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide an automatic folding and stacking method for washable wrinkled abdominal pads. The automatic folding of washable wrinkled abdominal pads maintains efficient and stable folding quality. Only manual assistance is required for feeding, reducing labor costs and improving processing efficiency. The multi-segment folding in both the horizontal and vertical directions results in stable and aesthetically pleasing folding, facilitating packaging and stacking, and ensuring smooth connection. The device can be combined with an automatic feeding and unloading structure, showing broad optimization prospects and facilitating integration with automated production lines.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic folding and stacking method for water-washed wrinkled abdominal pads, which adopts an automatic folding and stacking device for water-washed wrinkled abdominal pads, the automatic folding and stacking device for water-washed wrinkled abdominal pads including a positioning and feeding structure.

[0006] The positioning and feeding structure includes a first support frame, on which are provided mutually cooperating conveyor rollers. Conveyor belts are fitted on the conveyor rollers and arranged symmetrically. Multiple sets of positioning pins are symmetrically arranged on the conveyor belts. The conveyor rollers are connected to the output end of the motor, and the motor is connected to the first support frame through a fixed base.

[0007] The first support frame has its feeding end hinged to one end of the storage plate via a connecting shaft. The storage plate is provided with a locking shaft, which engages with a locking block on the first support frame.

[0008] The folding and stacking method is as follows:

[0009] The washed wrinkled abdominal pad material is stacked on the storage plate. The operator approaches the station and feeds the material onto the conveyor belt in sequence, and fixes the four corners of the washed wrinkled abdominal pad with positioning nails.

[0010] The two motors work intermittently, relying on the characteristics of servo motors, to allow materials to enter the gripping station in sequence;

[0011] After entering the gripping station, the first servo robot moves onto it, and the first and second electric push rods work to grip the material. After retracting, the first servo robot moves laterally to the placement position. The first and second sensors work together, and the first electric push rod outputs and lowers one side of the washed wrinkled abdominal pad material. Then, the first electric push rod retracts and the first servo robot continues to move laterally to the position where the first and third sensors work together. The second electric push rod outputs and lowers the other side of the washed wrinkled abdominal pad material. Finally, the second electric push rod retracts and the first servo robot moves laterally in the opposite direction to return to the gripping station directly above it.

[0012] Fourth, the washed wrinkled abdominal pad material is folded twice to form a three-layer stack. The folding plates on both sides flip in turn, causing the washed wrinkled abdominal pad material to be folded twice more until it is fully folded.

[0013] The second servo robot works, driving the push plate to move laterally and push the folded, wrinkled abdominal pad to move and unload. After unloading, it moves back to the initial position to complete one folding and stacking of the folded, wrinkled abdominal pad.

[0014] Repeat steps one through five above to continuously fold and stack the washable wrinkle-reducing abdominal pad material.

[0015] In a preferred embodiment, the automatic folding and stacking device for the water-washed wrinkled abdominal pad further includes a feeding and folding structure and a folding and unloading structure. The feeding and folding structure includes a mounting frame, on which a limiting slide rail and a first servo manipulator that cooperates with the two are provided. A fixed frame is symmetrically provided on the first servo manipulator. A first electric push rod and a second electric push rod that cooperate with each other are symmetrically provided on the symmetrically provided fixed frame. The output ends of the first electric push rod and the second electric push rod are both provided with gripping and releasing heads. A first sensor is provided on the fixed frame near the first electric push rod.

[0016] The folding unloading structure includes an operating table, which is connected to the positioning and feeding structure via a second support frame. The operating table is also connected to the feeding and folding structure via a side plate. The operating table is equipped with a limiting track, a placement slot, and a second servo manipulator that works in conjunction with the three components. The second servo manipulator is connected to a push plate via a connecting arm. The operating table is also equipped with a second sensor, a third sensor, a placement position, and multiple adjustment slots. A folding plate is placed in the adjustment slot, and the folding plate is connected to a servo motor mounted on the operating table via a rotating shaft.

[0017] In a preferred embodiment, the conveyor roller is provided with a positioning groove that cooperates with the conveyor belt.

[0018] In a preferred embodiment, the gripping head is a negative pressure suction cup, a clamp, or a gauze picking needle.

[0019] In a preferred embodiment, the motor is a servo motor.

[0020] In a preferred embodiment, the plurality of adjustment slots are two in number and symmetrically arranged on both sides of the placement position.
