[0108] S3. Open clamp 2 7, the sensor inside counter 9 switches to detection mode, the feeding mechanism 5 pushes the material to the counting area, counter 9 detects that the material is in place, then stops the feeding mechanism 5, counter 9 moves back Lmm relative to the direction of the wire entry into the encoder's soft limit area, so that the servo positioning and counting are cleared, then the sensor inside counter 9 switches to counting mode, moves forward and starts counting. If the lever cylinder moves Kmm and still cannot reach the full count, counter 9 returns. At the same time, open the feeding mechanism 5 and switch the sensor inside counter 9 to detection mode. When the feeding mechanism 5 pushes the material to the point that the sensor inside counter 9 detects, stop the feeding mechanism 5, counter 9 moves back Lmm relative to the direction of the wire entry into the encoder's soft limit area, so that the servo positioning and counting are cleared, then the sensor switches to counting mode, moves forward and starts counting, and waits after reaching the full count. L is the effective distance for counter 9 to enter the encoder's soft limit area, K is the distance of the total wire thickness P to be counted multiplied by the safety factor c, and c is 2.

[0109] S4. When the lever cylinder pushes the material to the storage tray area, the feeding mechanism 4 and clamp 3 8 are opened to check if there are bags in the bagging area. If so, the counter 9 in standby state is opened to continue counting and the material is pushed to the storage tray area. The receiving rod 19 of the receiving module extends to the receiving station, so that the feeding rod 18 and the receiving rod 19 are close together in the same straight line and the receiving rod is directly above the storage tray. Then the feeding mechanism 4 pushes the material from the feeding rod 18 to the receiving rod 19. The receiving rod 19 retracts, so that the material received by the receiving rod 19 falls into the storage tray of the pushing module. The storage tray 3 moves forward. After the storage tray 3 is in place, the bagging mechanism 12 pushes the material into the bag. The S4 action can be repeated m times to complete m bagging actions, where m is 3.

[0112] Preferably, in S2, manual feeding requires the use of a specified tooling. The tooling requires that the length of the dental floss string cannot exceed the distance between clamp one and clamp two, and that the material must be pushed into the safe zone during feeding.

[0113] Preferably, the counter 9 is equipped with a controller, which is used to calculate the return distance of Lmm in S3, starting from the return position. The controller is used to receive information from the counter 9 and can control the mode of the counter 9.

The receiving rod 19 of the receiving module extends to the receiving position, so that the feeding rod 18 and the receiving rod 19 are close to each other and in the same straight line, with the receiving rod directly above the storage tray. Then the feeding mechanism 4 pushes the material from the feeding rod 18 to the receiving rod 19. The receiving rod 19 retracts, so that the material received by the receiving rod 19 falls into the storage tray of the pushing module. The storage tray 3 moves forward. After the storage tray 3 is in place, the bagging mechanism 12 pushes the material into the bag. The S4 action can be repeated m times to complete m bagging actions, where m is 3.

[0134] S5, the bag-taking mechanism 16 sucks down the bag, the bag-feeding clamp 13 sends the bag to the bag-opening station, the bag-opening mechanism 15 opens the bag, the bag-opening motor 17 opens the bag to the required size for bagging, the tray 11 moves to send the bag to the bagging station, and then waits for the storage tray 3 to enter.

[0135] After S6 and m bag insertions are completed, the bag-supporting motor 17 retracts, the tray 11 returns to its original position, and the next set of bag-feeding clamps 13 sends the full bag to the hot-pressing area, where it is sealed by the sealing machine 10 and finally discharged from the finished product outlet 2.

[0136] In S2, manual feeding requires the use of designated tooling. The tooling requires that the length of the dental floss string cannot exceed the distance between clamp one and clamp two, and the material must be pushed into the safe zone during feeding.

[0137] The counter 9 contains a controller, which is used to calculate the return distance of Lmm in S3, starting from the return position. The controller is used to receive information from the counter 9 and can control the mode of the counter 9.

[0138] The packaging speed of a single packaging machine of the present invention is on average 40-50 stacks of dental floss per minute (approximately 1000 dental flosses per minute).

Claims

1. A bagged floss packaging machine characterized by, include: The module includes a feeding module, a sorting module, a delivery module, a receiving module, and a pushing module. The feeding module is used to input the dental floss to be packaged and pass it to the finishing module; The sorting module is used to sort the input dental floss and form floss piles, where each floss pile contains a predetermined number of flosses. The sorting module includes a feeding mechanism, a counter, and a lever cylinder. The feeding mechanism pushes the floss to the counting area. The counter detects that floss has arrived and then stops the feeding mechanism. The counter moves backward Lmm relative to the direction in which the floss entered, entering the encoder's soft limit area, resetting the servo positioning and count to zero. Then, the sensor inside the counter switches to counting mode, moves forward, and starts counting. If the lever cylinder moves Kmm but still cannot reach the full count, the counter returns, and simultaneously opens the feeding mechanism, and the floss is placed into the counting area. The sensor inside the counter switches to detection mode. When the feeding mechanism pushes the material to the point where the sensor inside the counter detects it, the feeding mechanism stops. The counter moves backward Lmm relative to the direction in which the wire enters, entering the soft limit area of ​​the encoder. This resets the servo positioning and counting to zero. Then, the sensor switches to counting mode, moves forward, and starts counting. After reaching the full count, it waits for the next step. L is the effective distance for the counter to enter the soft limit area of ​​the encoder. K is the distance of the total thickness P of the wire to be counted multiplied by the safety factor c, where c is 2. After counting the wire, the lever of the lever cylinder inserts the wire at a designated position, separating the wire pile from the entire string of wire. The feeding module is used to receive a stack of dental floss from the sorting module and transport the stack of dental floss to the subsequent receiving module. The feeding module is equipped with a feeding rod for suspending the stack of dental floss. The receiving module is used to receive the dental floss stack from the feeding module and transfer the dental floss stack to the pushing module; the receiving module is provided with a receiving rod and a first driving mechanism, the first driving mechanism drives the receiving rod to alternately move between the receiving position and the dropping position, wherein when the receiving rod is alternately in the receiving position, the receiving rod cooperates with the feeding rod of the feeding module, so that the dental floss stack suspended on the feeding rod is transferred to the receiving rod; The pushing module is used to receive the dental floss stack from the receiving module and push the dental floss stack into a packaging container, which is used to accommodate the dental floss stack.
