Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric production technology, and in particular to an automated production method for medical gloves. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber, polyester fiber (abbreviated as: PET) material, and is made through needle punching process, which can produce different thicknesses, feel, hardness, etc.

[0003] Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, lightness, flame retardancy, non-toxicity, odorlessness, low price, and recyclability. They can be used in various industries, such as sound insulation, heat insulation, heating elements, masks, clothing, medical applications, and filling materials.

[0004] Existing medical gloves made from nonwoven fabric are produced using a medical glove cutting device, as detailed in patent CN202122485482.2. However, this device typically requires a worker to be present to monitor the process, in case the nonwoven fabric roll cannot be fed in a timely manner, or if the forming and cutting components continue to operate after the nonwoven fabric roll has been used, resulting in mechanical damage. Therefore, fully automated production cannot be achieved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automated production method for medical gloves, thereby solving the problem that the existing technology cannot fully realize the automated production of medical gloves.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automated production method for medical gloves, the innovation of which is: including a sensing system, an alarm device, a system switch, a glove cutting device and a controller, wherein the sensing system, the alarm device, the system switch and the glove cutting device are all connected to the controller;

[0007] The glove cutting device includes an alignment component, a forming component, a cutting component, and a finished product box;

[0008] The sensing system includes a first position sensor, a second position sensor, and a third position sensor. The first position sensor is installed on the feeding side of the forming component of the glove cutting device, the second position sensor is installed on the feeding side of the cutting component of the glove cutting device, and the third position sensor is installed inside the finished product box of the glove cutting device.

[0009] The method for automating the production of medical gloves using the above structure includes the following steps:

[0010] S1. Power On: Turn on the system switch to power on;

[0011] S2, Feeding: The first non-woven fabric roll and the second non-woven fabric roll are respectively installed on the first unwinding roller and the second unwinding roller using a robotic arm; at the same time, the signals of the first and second position sensors are detected. If both the first and second position sensors detect the presence of non-woven fabric, proceed to S3; otherwise, proceed to S1.

[0012] S3 Alignment: Align and press the first nonwoven fabric on the first nonwoven fabric roll and the second nonwoven fabric on the second nonwoven fabric roll using the alignment component to form a double-layer fabric. At the same time, the first and second position sensor signals are detected. If the first position sensor detects that the nonwoven fabric is not present, an alarm is issued and the ultrasonic hot melt welding machine is shut down, and the process proceeds to S5. If the second position sensor detects that the nonwoven fabric is not present, an alarm is issued and the ultrasonic hot melt welding machine and the cutting component are shut down, and the process proceeds to S2.

[0013] S4. Hot melt forming: The double-layer fabric is conveyed to the forming component and continuously hot melt forming of the glove shape and the long edge of the double-layer fabric are performed on the double-layer fabric by an ultrasonic hot melt welding machine.

[0014] S5. Cutting and shaping: The double-layer fabric that has been thermoformed is conveyed to the cutting assembly for the separation of finished gloves and waste blocks;

[0015] S6. Waste recycling: The finished gloves and waste blocks are transported to the conveyor belt, and the middle part of the finished gloves in the double-layer fabric after cutting and the two sides of the length of the finished gloves are pressed respectively. The waste blocks are then recycled by the winding roller.

[0016] S7. Finished product collection: The remaining finished gloves from S5 fall from the conveyor belt into the finished product box for automatic collection. At the same time, the third position sensor detects the signal. If the finished product box is full of finished gloves, an alarm is issued and it is determined whether to continue feeding. If yes, proceed to S2; otherwise, proceed to S8.

[0017] S8, End.

[0018] Furthermore, the alignment component is used to align and press the first nonwoven fabric on the first nonwoven fabric roll and the second nonwoven fabric on the second nonwoven fabric roll to form a double-layer fabric.

[0019] Furthermore, the molding assembly includes an ultrasonic hot melt welding machine, which is set on the discharge side of the pressing assembly, for continuously performing glove-shaped hot melt molding and hot melt molding at the long edge of the double-layer fabric on the double-layer fabric.

[0020] Furthermore, the cutting assembly includes a support roller and a cutting roller. A first metal cutting strip and a second metal cutting strip are fixedly connected on the cutting roller. The first metal cutting strip forms a closed cutting glove shape, used to continuously cut the glove shape formed by heat fusion on the double-layer fabric completely, resulting in a finished glove. The width of the finished glove is 'a'. The waste area on the outer side of the double-layer fabric is the scrap area. The second metal cutting strip is horizontally positioned in the middle of the first metal cutting strip, connecting its two ends. The support roller has cutting grooves corresponding to the first and second metal cutting strips. The cutting roller and support roller work together to continuously cut the double-layer fabric in the scrap area between two adjacent finished gloves, dividing the scrap area along its length into two unconnected scrap blocks. After the double-layer fabric is cut, the distance between two adjacent finished gloves and the length of the second metal cutting strip are both 'b', and 'a' > 2b.

[0021] Furthermore, the glove cutting device also includes a pressing assembly, which is located near the input end of the conveyor belt and includes a main pressing component and an auxiliary pressing component;

[0022] The main pressing component includes a fixed pressing roller, a movable pressing roller, and several pressing belts for connecting the fixed pressing roller and the movable pressing roller. The extending direction of the pressing belt is consistent with the extending direction of the conveyor belt. The fixed pressing roller and the movable pressing roller are arranged parallel to each other, and the distance between the fixed pressing roller and the movable pressing roller is c, where c > a + 2b. The main pressing component is set on the transmission belt and is located vertically above the finished glove, so that the fixed pressing roller is located between the cutting component and the movable pressing roller, and the pressing belt presses the middle part of the finished glove in the double-layer fabric after cutting.

[0023] The auxiliary pressing component includes an auxiliary pressing strip, the extension direction of which is consistent with the conveyor belt. The auxiliary pressing component is symmetrically arranged on the transmission belt at both sides of the pressing strip, and is used to press the finished glove at both sides of its length.

[0024] Furthermore, if multiple boxes of finished gloves need to be produced during the production process, a counting device and a second robotic arm are also required. The counting device is connected to the controller. When the controller detects that the finished box is full of finished gloves in S7, the count in the counting device is incremented by one. At the same time, the second robotic arm is used to remove the finished box full of finished gloves and place the next empty finished box until the number of finished boxes full of finished gloves reaches the target.

[0025] The advantages of this invention are:

[0026] (1) In this invention, a sensing system is used to automatically detect whether the first and second non-woven fabrics are missing during the production process of the glove cutting device, and whether the finished product box is full of finished gloves. Then, the controller is used to control the alarm device and the robot to perform corresponding operations based on the detection results. The whole process does not require human intervention and can realize the fully automated production of medical gloves.

[0027] (2) In the production process of the present invention, if it is necessary to produce multiple finished boxes of finished gloves, a counting device and a second robot are also required. The counting device is connected to the controller. When it is detected in S7 that the finished box is full of finished gloves, the count in the counting device is incremented by one. At the same time, the second robot is used to move the finished box full of finished gloves away and place the next empty finished box until the number of finished boxes full of finished gloves reaches the target and then stops.
