Description

Technical Field

[0001] The present invention relates to the technical field of glove folding equipment, and particularly to an automatic shaping and folding machine for latex rubber medical gloves. Background Art

[0002] Gloves are hand warmers or labor protection supplies, and there are also decorative ones. In some industries where gloves are replaced frequently, it is usually recommended to use disposable gloves, which can not only avoid cross-infection but also greatly save the replacement cost. For example, in industries with high hygiene requirements such as the medical industry, food processing industry, and catering industry. Disposable gloves used in the catering industry are further guaranteed in terms of their hygiene performance, and each glove or pair of gloves is independently packaged and heat-sealed. At this time, in order to adapt to the use of most customers, the gloves are usually thin and large. Therefore, the gloves need to be folded before packaging and heat-sealing. Due to the existing gloves being thin and large, and the folding times of the packaging machine being few, the packaging bags required for packaging are large, which is not convenient for glove packaging and has low packaging efficiency.

[0003] To solve this technical problem, the Chinese utility model patent application with the application number CN201821919013.9 discloses a glove folding and packaging machine, including a frame. A material feeding device, a film feeding and unwinding device, a film heat-sealing device, and a folding device for folding the material are provided on the frame. The folding device includes a first folding mechanism, a second folding mechanism, and a three-four fold mechanism. The first folding mechanism folds the material on the material feeding device for the first time and sends the material to the second folding mechanism. The second folding mechanism folds the material for the second time and sends the material to the three-four fold mechanism. The film heat-sealing device heat-seals the film unwound from the film feeding and unwinding device into a packaging bag with an opening. The three-four fold mechanism cooperates with the film heat-sealing device to fold the material and insert it into the packaging bag. The present invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life.

[0004] However, during the process of folding gloves by the above mechanism, there is a transportation of gloves. Since current medical surgical gloves and medical examination gloves are made of rubber or nitrile, the gloves are in a soft state. If there is transportation of gloves during the folding process, the gloves that are not fully folded are likely to become loose, reducing the glove folding efficiency and requiring manual re-selection and sorting, which increases the production cost. Summary of the Invention

[0029] Please refer to Figures 1 to 7 , an automatic shaping and folding machine for latex rubber medical gloves, comprising a hanging arm tooling 2, a tooling rotation driving mechanism 1 for driving the rotation of the hanging arm tooling 2, a central shaft 3 movably disposed within the hanging arm tooling 2, and a central shaft driving mechanism 4 for driving the telescopic movement of the central shaft 3; the hanging arm tooling 2 is communicated with a first pneumatic assembly 5; the central shaft 3 is communicated with a second pneumatic assembly 6; a sensor 10 for detecting the position of the thumb of the glove is disposed on one side of the hanging arm tooling 2 and a second folding mechanism 8 is located on one side of the sensor 10, and the second folding mechanism 8 is configured to fold the thumb to the palm of the glove; a first folding mechanism 7 for folding the remaining four fingers of the glove to the palm of the glove is installed on one side of the hanging arm tooling 2.

[0030] In practical applications, the staff manually hangs the arm of the glove on the outside of the hanging arm tooling 2. The first air pressure component 5 supplies low-pressure compressed air to the glove, causing the glove to expand. The tooling rotation drive mechanism 1 drives the hanging arm tooling 2 to rotate. At the same time, the position of the thumb of the glove is detected and sensed through the sensor 10. The position sensor 10 is preferably a photoelectric diffuse reflection sensor. After the sensor 10 senses the position of the thumb of the glove, the tooling rotation drive mechanism 1 stops driving the hanging arm tooling 2 to rotate. The central axis drive mechanism 4 drives the central axis 3 to telescopically move inside the hanging arm tooling 2, so that the central axis 3 is inserted into the glove from the hanging arm tooling 2. Then, the second air pressure component 6 pumps out the air inside the glove, causing the glove to adsorb on the outside of the central axis 3. The first folding mechanism 7 starts to operate to a specified position, and then the second folding mechanism 8 is started to fold the thumb towards the palm. After that, the first folding mechanism 7 continues to operate to fold the remaining four fingers of the glove towards the palm and wrap the thumb inside. Then, the central axis drive mechanism 4 drives the central axis 3 to retract into the hanging arm tooling 2 with the glove with five folded fingers adsorbed. The second folding mechanism 8 stops operating, and the first folding mechanism 7 returns to its original position. The first air pressure component 5 outputs positive-pressure high-pressure compressed gas to push the arm of the glove off the hanging arm tooling 2, and makes the arm of the glove complete the inner wall turning outwards to wrap the thumb and the remaining four fingers of the glove and completely cover the outside of the central axis. After that, the second air pressure component 6 stops the negative pressure to prepare for the glove to separate from the central axis 3. By outputting positive-high-pressure compressed air through the second air pressure component 6, the glove is pushed out from the central axis 3 to complete the folding and blanking of the glove. Finally, the central axis drive mechanism 4 drives the central axis 3 to retract into the hanging arm tooling 2; two complete units each composed of the tooling rotation drive mechanism 1, the hanging arm tooling 2, the central axis 3, the central axis drive mechanism 4, the first air pressure component 5, the second air pressure component 6, the first folding mechanism 7, the second folding mechanism 8 and the position sensor 10 can be symmetrically installed to simultaneously complete the folding of a pair of gloves. According to production needs, multiple workstations can also be made; the present invention has the characteristics of fast glove folding speed and high automation degree, and the gloves do not need to be transported during the folding process, effectively improving the production efficiency and reducing the production cost.

The output end of the first servo motor 101 is drivingly connected to a tooling driving gear 103, and the tooling driving gear 103 is drivingly connected to one end of the hanging arm tooling 2 through a tooling driving belt 102. In this embodiment, when the first servo motor 101 is turned on, the first servo motor 101 drives the tooling driving gear 103 to rotate, and the tooling driving gear 103 drives the hanging arm tooling 2 to rotate through the tooling driving belt 102.

[0032] Please refer to Figures 1 to 7 , the central axis driving mechanism 4 includes a driving cylinder 41. The driving cylinder 41 is installed on the side of the hanging arm tooling 2 away from the first folding mechanism 7. The piston rod of the driving cylinder 41 is connected to a connecting member 42. One end of the connecting member 42 is fixedly connected to the driving cylinder 41, and one end of the connecting member 42 is fixedly connected to the central axis 3. The hanging arm tooling 2 is in the shape of a hollow cylinder. In this embodiment, the driving cylinder 41 drives the connecting member 42 to drive the central axis 3 to perform reciprocating telescopic motion in the hanging arm tooling 2.

[0033] Please refer to Figures 1 to 7 , the first air pressure assembly 5 includes a plurality of first positive pressure air holes 51 provided at one end of the hanging arm tooling 2 close to the central axis 3. The plurality of first positive pressure air holes 51 are arranged at equal intervals.

The plurality of first positive pressure air holes 51 are all communicated with the first positive pressure solenoid valve 52, and the plurality of first positive pressure air holes 51 are all communicated with the second positive pressure solenoid valve 9. In this embodiment, after the arm of the glove is sleeved on the hanging arm tooling 2, the first positive pressure solenoid valve 52 is started, and low-pressure compressed air is discharged from the positive pressure air compressor into the plurality of first positive pressure air holes 51 through the air delivery pipe and then discharged into the glove to inflate and expand the glove. After the fingers of the glove are folded, the central axis 3 retracts into the hanging arm tooling 2 under the drive of the central axis driving mechanism 4, and the second positive pressure solenoid valve 9 is started. Positive pressure high-pressure compressed air is discharged from the positive pressure air compressor into the plurality of first positive pressure air holes 51 through the air delivery pipe and then discharged, pushing out the arm of the glove on the hanging arm tooling 2 and turning the arm part of the glove outwards to wrap the thumb and the remaining four fingers of the glove.

The plurality of negative pressure air holes 61 communicate with the negative pressure solenoid valve 62, and the plurality of negative pressure air holes 61 also communicate with the second positive pressure solenoid valve 9. In this embodiment, when the negative pressure solenoid valve 62 is started, under the action of a negative pressure air compression pump, the air in the glove sequentially passes through the plurality of negative pressure air holes 61, the air delivery pipe, and is compressed and discharged under negative pressure, so that the glove is adsorbed on the surface of the central shaft 3. After the arm of the glove is folded, the negative pressure solenoid valve 62 is closed, and at the same time, the second positive pressure solenoid valve 9 is started. The plurality of negative pressure air holes 61 output compressed air with positive pressure and high pressure to blow the glove off the central shaft 3, realizing blanking.

Then, by starting the second folding mechanism 8, the thumb is folded towards the palm. After that, the folding driving mechanism 72 drives the folding frame 71 to continue moving under the guiding action of the folding guiding mechanism 73, folding the remaining four fingers of the glove towards the palm, and wrapping the thumb inside. Then, the second folding mechanism 8 stops operating, and the folding driving mechanism 72 drives the folding frame 71 to move back to the starting position.

[0036] Please refer to Figures 1 to 7 , the folding frame 71 includes a folding moving frame 711 and a finger folding plate 712 fixedly installed at one end of the folding moving frame 711. The folding moving frame 711 is slidably connected to the folding guiding mechanism 73. The cross-section of the finger folding plate 712 is in a "U" shape and matches the shape and size of the central shaft. In this embodiment, the folding driving mechanism 72 drives the folding moving frame 711 to move under the action of the folding guiding mechanism 73, driving the second folding mechanism 8 to fold the thumb towards the palm. After that, the folding moving frame 711 drives the finger folding plate 712 to fold the remaining four fingers of the glove towards the palm and wrap the thumb inside. The finger folding plate 712 is in a "U" shape and matches the shape and size of the central shaft, facilitating the cooperation with the central shaft 3 to fold the remaining four fingers of the glove towards the palm, so that the remaining four fingers of the glove are all attached to the palm of the glove.

[0037] Please refer toFigures 1 to 7 , the folding drive mechanism 72 includes a second servo motor 721 for driving the folding frame 71 to move. The second servo motor 721 is connected to a coaxial gear set 723 through a first synchronous belt 722. The coaxial gear set 723 is connected to a roller 725 through a second synchronous belt 724. Both the roller 725 and the coaxial gear set 723 are rotatably connected to the folding guide mechanism 73, and the folding guide mechanism 73 is fixedly connected to the second synchronous belt 724.

At the same time, the folding frame 71 and the guide wheel 733 move under the action of the guide groove 736. When the guide wheel 733 moves on the slope position of the guide groove 736, the guide wheel 733 drives the folding frame 71 to move longitudinally and slide down on the longitudinal guide rail 731. At the same time, the folding frame 71 moves horizontally under the drive of the folding driving mechanism 72 along with the longitudinal guide rail 731. The telescopic rod 732 stretches and changes the inclination angle to play a traction role on the guide wheel 733.

And the folding frame 71 moves horizontally under the drive of the folding driving mechanism 72 along with the longitudinal guide rail 731. At the same time, the telescopic rod 732 accelerates stretching and changes the inclination angle to limit the sliding speed of the guide wheel 733 and enhance the stability of the movement of the folding frame 71. Then the folding driving mechanism 72 drives the longitudinal guide rail 731 to move horizontally in the reverse direction, and then the longitudinal guide rail 731 drives the folding frame 71 to move horizontally in the reverse direction to complete the folding of the four fingers of the glove.
