Description

Technical Field

[0001] This invention belongs to the field of medical dressing production technology, and specifically relates to an automatic medical dressing sheet filling device and a sheet filling method. Background Technology

[0002] Chinese patent document CN114476210A discloses a method for filling medical dressing pieces (a patent technology previously applied for by our company). The main working principle is as follows: medical dressing pieces are loaded into a raw material tank, ensuring that the folded corners of the medical dressing pieces face upwards during the loading process; a discharge hook is provided at the lower end of the raw material tank, and the top of the discharge hook is connected to the discharge port; a rotating material handling device is provided at the discharge hook, and the rotating material handling device is connected to a feeding device; the piece-feeding device divides and conveys the medical dressing pieces to an equally spaced filling belt, which is used to transport the medical dressing pieces to a packaging machine for packaging.

[0003] The drawback of the above method is that it cannot guarantee that only one medical dressing is hooked at a time, because several medical dressings are stuck together, and when hooking one medical dressing, it is easy to bring out other medical dressings. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic medical dressing sheet-separating and filling device and a sheet-separating and filling method, which can ensure that only one sheet of medical dressing is extracted at a time, making it less likely to pull out other medical dressings, thus ensuring the quality of the filling material.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An automatic medical dressing sheet filling device includes a hopper, and a rotating material picking mechanism is installed at the outlet of the hopper. The rotating material picking mechanism includes a rotating disk, which is driven to rotate by a rotating disk driving component. A suction cup and a gripper mechanism are installed on the rotating disk. The rotary material handling mechanism also includes a suction cup in / out cam, which is used to cooperate with the suction cup to complete the in / out operation. The suction cup is slidably mounted on the rotary disk. The rotary material handling mechanism also includes a gripper mechanism entry / exit cam, which is used to cooperate with the gripper mechanism to complete the entry and exit operation. The gripper mechanism is slidably mounted on the rotary table.

[0006] Preferably, the gripper mechanism includes a connecting rod and a gripper, the connecting rod being used to drive the gripper to open and close; the connecting rod being used to cooperate with the gripper closing cam to complete the reciprocating movement operation.

[0007] Preferably, the rotary disk driving component is a rotary disk drive motor; the rotary disk drive motor drives the rotary disk to rotate through a drive wheel, a driven wheel, and a transmission component; the driven wheel is coaxially mounted with the rotating shaft of the cam rotary motor, and a bushing is provided on the outside of the rotating shaft of the cam rotary motor. The bushing is connected to the driven wheel, and the end of the bushing is connected to the rotary disk. The bushing is rotatably mounted on the equipment frame; the cam rotary motor is used to drive the gripper closing cam, the gripper mechanism in-and-out cam, and the suction cup in-and-out cam to rotate synchronously.

[0008] Preferably, the suction cup, the gripper mechanism, and the connecting rod are all provided with guide wheels at their ends. The guide wheel of the suction cup contacts the edge of the suction cup entry / exit cam, the guide wheel of the gripper mechanism contacts the edge of the gripper mechanism entry / exit cam, and the guide wheel of the connecting rod contacts the edge of the gripper closing cam.

[0009] Preferably, the gripper closing cam, the gripper mechanism entry and exit cam, and the suction cup entry and exit cam are axially arranged on the rotating shaft of the cam rotary motor; the other end of the bushing is connected to the cam rotary motor, or the other end of the bushing is not connected to the cam rotary motor.

[0010] Preferably, the suction cup and gripper mechanism are mounted on the rotating disk by a tension spring.

[0011] Preferably, a feeding belt is provided at the bottom of the hopper, and the feeding belt is driven by a feeding motor. Preferably, a vibration device is installed on the silo.

[0012] An automatic gauze pad separation and filling method is disclosed, which employs an automatic medical dressing separation and filling device. The separation and filling method is as follows: S1. Place the material pieces that need to be sliced ​​into the hopper; S2. The rotating disk is driven by the rotating disk drive component. When the suction cup rotates to the outlet of the hopper, the rotating disk stops. S3. The cam rotary motor drives the gripper closing cam, the gripper mechanism entry and exit cam, and the suction cup entry and exit cam to rotate synchronously. When the suction cup in / out cam rotates, it will first drive the suction cup to extend forward, and the suction cup will pick up the first piece of material. Then the suction cup will retract backward and drive the first piece of material to bend. When the gripper mechanism's in-and-out cam rotates, it extends the gripper mechanism forward. At the same time, when the gripper closing cam rotates, it opens the gripper. As the gripper mechanism's in-and-out cam and gripper closing cam continue to rotate, the gripper picks up the first piece of material. S4, Working Condition 1: When the bushing is connected to the cam rotary motor, the cam rotary motor stops operating. The rotary disk drive component continues to drive the rotary disk to rotate, which will simultaneously drive the gripper closing cam, the gripper mechanism in and out cam, the suction cup in and out cam, and the cam rotary motor to rotate. Operating Condition 2: When the bushing is not connected to the cam rotary motor, the cam rotary motor and the turntable rotary drive motor start synchronously, and the output speeds of the cam rotary motor and the turntable rotary drive motor are the same, so that they synchronously drive the gripper closing cam, the gripper mechanism in and out cam, the suction cup in and out cam, and the turntable to rotate synchronously. S5. When the first material piece rotates to the filling station, the rotary disk drive component stops working, and the cam rotation motor moves the gripper closing cam, the gripper mechanism in / out cam, and the suction cup in / out cam relative to the rotary disk, and drives the gripper to release. The first material piece is successfully filled, and the single material piece is successfully filled.

[0013] The present invention can achieve the following beneficial effects: This invention ensures that only one piece of medical dressing is extracted at a time, preventing other medical dressings from being pulled out and guaranteeing the quality of the filling material. It also enables continuous automatic segmentation and filling of gauze pads, reducing manual labor and improving the efficiency of gauze pad packaging. Attached Figure Description

[0016] Example 1: Preferred solutions include Figures 1 to 7As shown, an automatic medical dressing sheet filling device includes a hopper 1. A rotating material picking mechanism is installed at the outlet of the hopper 1. The rotating material picking mechanism includes a rotating disk 201, which is driven to rotate by a rotating disk driving component. A suction cup 202 and a gripper mechanism 203 are installed on the rotating disk 201. The rotary material handling mechanism also includes a suction cup in / out cam 204, which is used to cooperate with the suction cup 202 to complete the in / out operation. The suction cup 202 is slidably mounted on the rotary disk 201. The rotary material handling mechanism also includes a gripper mechanism entry / exit cam 205, which is used to cooperate with the gripper mechanism 203 to complete the entry and exit operation. The gripper mechanism 203 is slidably mounted on the rotary disk 201.

[0017] In this embodiment, the cams include three types: a gripper closing cam 206, a gripper mechanism entry / exit cam 205, and a suction cup entry / exit cam 204. A set of suction cups 202 and gripper mechanisms 203 is provided on the rotary disk 201. A sliding groove is provided on the rotary disk 201, and the suction cups 202 and gripper mechanisms 203 are slidably mounted on the rotary disk 201 via sliders. The function of the suction cups 202 is to bend the upper part of a single auxiliary material sheet, making it easier for the gripper mechanisms 203 to clamp the upper edge of the single auxiliary material sheet. After the gripper mechanisms 203 clamp the single auxiliary material sheet, the rotary disk 201 rotates, causing the auxiliary material sheet to rotate, and finally, the gripper mechanisms 203 release the material to complete the unloading process.

[0018] In this embodiment, the suction cup 202 is a component based on the principle of negative pressure adsorption. As an alternative, the suction cup 202 can be selected with a suitable material picking mechanism according to the characteristics of the material. For example, when the material is a piece of gauze, it can also be picked up by pasting or hooking. Furthermore, the gripper mechanism 203 includes a connecting rod 203.1 and a gripper 203.2. The connecting rod 203.1 is used to drive the gripper 203.2 to open and close; the connecting rod 203.1 is used to cooperate with the gripper closing cam 206 to complete the reciprocating movement operation.

[0019] The gripper mechanism 203 in this embodiment includes two grippers, one of which is fixed to the outer shell and the other is hinged to the outer shell. A connecting rod is used to drive the hinged gripper to rotate. Alternatively, the gripper mechanism 203 in this embodiment can be replaced by other equivalent mechanisms. For example, gripper 203.2 includes mating grippers, one of which is driven to move by connecting rod 203.1. The two grippers can be connected by an elastic element to provide a reset function.

[0020] Furthermore, the rotating disk driving component is a rotating disk drive motor 3; the rotating disk drive motor 3 drives the rotating disk 201 to rotate through a drive wheel, a driven wheel, and a transmission component; the driven wheel is coaxially mounted with the rotating shaft of the cam rotating motor 4, and a bushing is provided on the outside of the rotating shaft of the cam rotating motor 4. The bushing is connected to the driven wheel, and the end of the bushing is connected to the rotating disk 201. The bushing is rotatably mounted on the equipment frame; the cam rotating motor 4 is used to drive the gripper closing cam 206, the gripper mechanism entry and exit cam 205, and the suction cup entry and exit cam 204 to rotate synchronously.

[0021] Specifically, the cam rotary motor 4 is a motor with a self-locking function, while the turntable rotary drive motor 3 is a motor without a self-locking function; the gripper closing cam 206, the gripper mechanism entry and exit cam 205, and the suction cup entry and exit cam 204 are axially arranged on the rotating shaft of the cam rotary motor 4. The other end of the bushing is connected to the cam rotary motor 4, or the other end of the bushing is not connected to the cam rotary motor 4.

[0022] There are at least two possible combinations of interaction between the cam rotary motor 4 and the turntable rotary drive motor 3: Operating Condition 1: The cam rotary motor 4 can be a geared motor with a worm gear reducer. The external wiring of the cam rotary motor 4 is connected via slip rings. Because when the turntable rotary drive motor 3 drives the turntable 201 to rotate, it will also drive the cam rotary motor 4 to rotate. When the cam rotary motor 4 rotates, it can drive the three cams to rotate independently. At the same time, the rotation of the bushing will drive the turntable 201 and the cam rotary motor 4 to rotate. Therefore, when the turntable rotary drive motor 3 is working, it can drive the three cams and the cam rotary motor 4 to rotate synchronously.

[0023] Operating Condition 2: The cam rotary motor 4 and the turntable rotary drive motor 3 are independent of each other. In order to achieve synchronous rotation of the three cams and the turntable 201, it is necessary to control the output speed of the cam rotary motor 4 and the turntable rotary drive motor 3 so that the three cams and the turntable 201 remain relatively stationary.

[0024] Furthermore, guide wheels are provided at the ends of the suction cup 202, the gripper mechanism 203, and the connecting rod 203.1. The guide wheel of the suction cup 202 contacts the edge of the suction cup entry / exit cam 204, the guide wheel of the gripper mechanism 203 contacts the edge of the gripper mechanism entry / exit cam 205, and the guide wheel of the connecting rod 203.1 contacts the edge of the gripper closing cam 206. The guide wheels are used to reduce friction.

[0025] Furthermore, the suction cup 202 and the gripper mechanism 203 are mounted on the rotating disk 201 by a tension spring.

[0026] The rotary disk 201 rotates, and the gripper mechanism 203 and the suction cup 202 rotate with the rotary disk 201. The gripper closing cam 206, the gripper mechanism entry and exit cam 205, and the suction cup entry and exit cam 204 are connected into a whole by a connector. The three cams can rotate independently or rotate together with the rotary disk 201. Furthermore, a feeding belt 5 is provided at the bottom of the hopper 1, and the feeding belt 5 is driven by a feeding motor 6. A vibration device is installed on the hopper 1. The vibration device is used to loosen the material and prevent it from sticking together.

[0027] An automatic gauze pad separation and filling method is provided, employing an automatic medical dressing separation and filling device. The separation and filling method is as follows: S1. Place the material pieces that need to be sliced ​​into the hopper 1; S2. The rotating disk 201 is driven to rotate by the rotating disk drive component. When the suction cup 202 rotates to the outlet of the hopper 1, the rotating disk 201 stops. S3. The cam rotary motor 4 drives the gripper closing cam 206, the gripper mechanism entry and exit cam 205 and the suction cup entry and exit cam 204 to rotate synchronously. When the suction cup in / out cam 204 rotates, it will first drive the suction cup 202 to extend forward, and the suction cup 202 will pick up the first piece of material. Then the suction cup 202 will retract backward and drive the first piece of material to bend. When the gripper mechanism entry / exit cam 205 rotates, it will extend the gripper mechanism 203 forward. At the same time, when the gripper closing cam 206 rotates, it will open the gripper 203.2. As the gripper mechanism entry / exit cam 205 and the gripper closing cam 206 continue to rotate, the gripper 203.2 will pick up the first piece of material. S4, Working Condition 1: When the bushing is connected to the cam rotary motor 4, the cam rotary motor 4 stops operating. While the rotary disk drive component continues to drive the rotary disk 201 to rotate, it will simultaneously drive the gripper closing cam 206, the gripper mechanism entry and exit cam 205, the suction cup entry and exit cam 204, and the cam rotary motor 4 to rotate. Working condition 2: When the bushing is not connected to the cam rotary motor 4, the cam rotary motor 4 and the turntable rotary drive motor 3 start synchronously, and the output speeds of the cam rotary motor 4 and the turntable rotary drive motor 3 are the same, so that the gripper closing cam 206, the gripper mechanism in and out cam 205, the suction cup in and out cam 204 and the turntable 201 rotate synchronously. S5. When the first material piece rotates to the filling station, the rotary disk drive component stops working, and the cam rotary motor 4 moves to make the gripper closing cam 206, the gripper mechanism entry and exit cam 205 and the suction cup entry and exit cam 204 move relative to the rotary disk 201, and drive the gripper 203.2 to release. The first material piece is successfully filled, and the single material piece is successfully filled.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
