[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Refer to Figures 1 to 12 , the noodle card strapping machine includes a main body frame 1, and a noodle card feeding mechanism 3 and a center strap-passing mechanism 7 are provided on the main body frame 1.

[0033] Among them, the face card feeding mechanism 3 includes an upper fixed frame plate 3-3, a middle fixed plate 3-4, and four linear optical axes, namely linear optical axis 3-7, linear optical axis 3-8, linear optical axis 3-9, and linear optical axis 3-10. After passing through the four diagonal positions of the middle fixed plate 3-4, the upper ends of the four linear optical axes are fixedly connected to the upper fixed frame plate 3-3 to form a feeding mechanism framework. A face card pushing plate 3-6 is also sleeved on the four linear optical axes between the upper fixed frame plate 3-3 and the middle fixed plate 3-4. Above the face card pushing plate 3-6 is used to place face cards 3-14 (shown as stacked face cards), and below the face card pushing plate 3-6 is connected by the telescopic rod of a face card servo cylinder 3-11.

[0034] The center threading strap mechanism includes a main board 7-13 with a central hollow. Four push cylinders are installed on the hollow main board 7-13 in a central symmetry manner. The four push cylinders are respectively push cylinder 7-5, push cylinder 7-6, push cylinder 7-7, and push cylinder 7-8. A face card mold 7-1 is installed at the end of push cylinder 7-5, a face card mold 7-2 is installed at the end of push cylinder 7-6, a face card mold 7-3 is installed at the end of push cylinder 7-7, and a face card mold 7-4 is installed at the end of push cylinder 7-8. Each face card mold is provided with an air groove, and when the four face card molds are combined, the air grooves form an air path for guiding the strap to pass through. This air path includes an X-axis air path and a Y-axis air path. The X-axis air path includes an X-axis air inlet and an X-axis air outlet, and the Y-axis air path includes a Y-axis air inlet and a Y-axis air outlet.

[0035] Above the central hollow main board, there is a strap conveying mechanism 7-A. The strap conveying mechanism 7-A is connected to the Y-axis strap conveying pipeline 5 and the X-axis strap conveying pipeline 6. The strap threading mechanism includes a movable plate 7-22 that can move vertically up and down and an up and down moving bracket 7-21. The movable plate 7-22 and the up and down moving bracket 7-21 are respectively fixed by four optical axes. Each optical axis is sleeved with two upper and lower bushings. The four upper bushings of the four optical axes are fixed on the upper fixed plate 7-11 of the hanging strap conveying mechanism 7-A, and the four lower bushings are fixed on the lower long fixed plate 7-12. A moving cylinder 7-10 is fixed on the upper fixed plate 7-11, and the telescopic rod of the moving cylinder 7-10 is connected to the up and down moving bracket 7-21. In this way, the moving cylinder 7-10 can drive the strap conveying mechanism 7-A to move up and down.

[0036] The X-axis strap feeding group and the Y-axis strap feeding group are installed on the moving plate 7-22. The Y-axis strap feeding group includes a strap feeding auxiliary funnel 7-23 and a corresponding suction nozzle 7-19 arranged on the other side of the strap feeding auxiliary funnel 7-23. The X-axis strap feeding group includes a strap feeding auxiliary funnel (not shown in the figure) and a corresponding suction nozzle 7-17 arranged on the other side of the strap feeding auxiliary funnel (not shown in the figure). When the moving plate 7-22 moves downward so that the lower parts of the X-axis strap feeding group and the Y-axis strap feeding group are in contact with the combined surface card mold, the strap feeding auxiliary funnel 7-23 is docked with the Y-axis strap conveying pipeline 5, and the strap feeding auxiliary funnel (not shown in the figure) is docked with the X-axis strap conveying pipeline 6.

[0037] A surface card extraction mechanism is provided on the side of the strap conveying mechanism 7-A. The surface card extraction mechanism includes a surface card servo motor 7-9 and a rotating bracket 7-14 installed on the reduction gear shaft of the surface card servo motor 7-19. A surface card picking cylinder 7-15 is installed at the end of the rotating bracket 7-14. Four small suction cups 7-16 are installed on the surface card picking cylinder. The four small suction cups 7-16 are controlled by the surface card picking cylinder 7-15 to move up and down to contact the surface card, and then the suction cups generate suction to suck the surface card and lift the surface card as the surface card picking cylinder 7-15 rises.

[0038] In specific implementation, bushings are respectively installed near the four diagonals of the surface card pushing plate 3-6. The linear optical axes 3-7, 3-8, 3-9 and 3-10 pass through the bushings and indirectly penetrate the surface card pushing plate. The bushings make the surface card pushing plate 3-6 move more stably up and down on the four linear optical axes.

[0039] The worker places the whole bundle of surface cards 3-14 on top of the surface card pushing plate 3-6 of the surface card feeding mechanism 3, and then places the two straps into the Y-axis strap conveying pipeline 5 and the X-axis strap conveying pipeline 6 respectively. The surface card extraction mechanism extracts the topmost surface card on the surface card feeding mechanism 3 and places it above the middle of the combined four surface card molds. Strip-shaped holes for the straps to pass through are reserved around the surface card 3-14 during production. The X-axis air inlet, X-axis air outlet, Y-axis air inlet and Y-axis air outlet formed after the four surface card molds are combined correspond to the positions of the strip-shaped holes. The lower part of the strap feeding auxiliary funnel 7-23 presses on the surface of the surface card and is not blocked due to the position of the strip-shaped hole, so it is communicated with the Y-axis air inlet. The surface of the surface card above the Y-axis air outlet is not blocked due to the position of the strip-shaped hole, so it is communicated with the channel of the suction nozzle 7-19. The lower part of the strap feeding auxiliary funnel (not shown in the figure) presses on the surface of the surface card and is not blocked due to the position of the strip-shaped hole, so it is communicated with the X-axis air inlet. The surface of the surface card above the X-axis air outlet is not blocked due to the position of the strip-shaped hole, so it is communicated with the channel of the suction nozzle 7-17.

[0040] Then, the Y-axis strap conveyor line 5 and the X-axis strap conveyor line 6 respectively convey their own straps to the strap feeding auxiliary funnel 7-23 and the strap feeding auxiliary funnel (not shown in the figure). The suction nozzle 7-19 on the other side of the strap feeding auxiliary funnel 7-23 generates suction through a negative pressure fan, sucks the strap conveyed from the Y-axis strap conveyor line 5 through the strap feeding auxiliary funnel 7-23 into the lower Y-axis air inlet, and pulls it from the Y-axis air outlet to the suction nozzle 7-19. The suction nozzle 7-17 on the other side of the strap feeding auxiliary funnel (not shown in the figure) generates suction through a negative pressure fan, sucks the strap conveyed from the X-axis strap conveyor line 6 through the strap feeding auxiliary funnel (not shown in the figure) into the lower X-axis air inlet, and pulls it from the X-axis air outlet to the suction nozzle 7-17.

[0041] After that, the back card extraction mechanism resets, and the four back card molds retract outward by their respective pushing air cylinders. The straps are detached from the mold air grooves, and finally the back cards with the straps threaded through are received by the finished product output mechanism 4 below. The whole process repeats continuously, and the worker only needs to put new bundles of back cards into the back card feeding mechanism 3 and place the straps in an orderly manner on the two strap conveyor lines.

[0042] Continue to refer to Figure 2 、 Figure 10 Furthermore, as an improvement to the present invention, a labeling mechanism 2 is provided on the main body frame 1. The labeling mechanism includes an X-axis 2-1 composed of a horizontal slider assembly disposed on a Y-axis 2-2 composed of a vertical slider assembly to form a cross slide table. A label cylinder 2-6 is installed at the end of the Y-axis 2-2 that composes the vertical slider assembly, and a label suction nozzle 2-5 is installed on the label cylinder 2-6. One side of the label suction nozzle 2-5 is close to the output end of a label peeling machine 2-3.

[0043] During implementation, when the label peeling machine 2-3 cooperates with the labeling mechanism 2, only the label with the outer label paper peeled off needs to be in contact with the label suction nozzle 2-5, that is, after the label is output by the label peeling machine 2-3, it can be normally sucked by the label suction nozzle 2-5 when in contact. For corresponding requirements, commercially available label peeling machines can be of any brand and model. The label suction nozzle 2-5 uses a vacuum suction nozzle, and the vacuum suction nozzle has a vacuum sensor. The two are sold integrally or in a set in the market. After directly purchasing and assembling, the circuit can be assembled according to the instructions.

[0044] The PLC controller controls the servo motors of the X-axis 2-1 and Y-axis 2-2, moves the label suction nozzle 2-5 above the label 2-4, then controls the label cylinder 2-6 to descend, presses the label suction nozzle 2-5 on the upper surface of the label 2-4. After the vacuum sensor senses that the label suction nozzle 2-5 has firmly sucked the label, it controls the label cylinder 2-6 to rise, and the label suction nozzle 2-5 sucks the label 2-4 and detaches it from the label paper. Then, the X-axis 2-1 and Y-axis 2-2 act simultaneously to move the label suction nozzle 2-5 to a position above the face card feeding mechanism 3, and according to the pasting position, paste the top face card with the label. Then, the label suction nozzle 2-5 no longer generates suction, rises with the label cylinder 2-6, and returns to the position where the label is grabbed, waiting for the next round of labeling operation.

[0045] Further, as an improvement to the present invention, a suction-in-place sensor is provided on one side of the suction nozzle. Specifically, the Y-axis suction nozzle 7-19 is equipped with a suction nozzle sensor 7-20, the X-axis suction nozzle 7-17 is equipped with a suction nozzle sensor 7-18, and the moving plate 7-22 is also equipped with an auxiliary discharging cylinder 7-26. The auxiliary discharging cylinder 7-26 is equipped with an auxiliary discharging suction cup (not shown in the figure); a pressing cylinder is also installed above the corresponding in-bonding auxiliary funnel. Specifically, the in-bonding auxiliary funnel 7-23 corresponds to the Y-axis pressing cylinder 7-24, and the in-bonding auxiliary funnel (not shown in the figure) corresponds to the X-axis pressing cylinder 7-25.

[0046] During implementation, after the suction-in-place sensor senses that the binding tape has reached the position, it feeds back the signal to the PLC controller. The PLC controller controls the auxiliary discharging cylinder 7-26 to move downward so that the auxiliary discharging suction cup (not shown in the figure) sucks the face card. After sucking or simultaneously, it controls the Y-axis pressing cylinder 7-24 and the X-axis pressing cylinder 7-25 to press down to hold the ends of the two binding tapes to prevent the suction nozzles 7-19 and 7-17 at the other end from sucking the binding tape completely.

[0047] Continue to refer to Figure 3 Furthermore, as an improvement to the present invention, the face card feeding mechanism 3 further includes a lower fixed plate 3-5. The lower fixed plate 3-5 is connected at the ends of four linear optical axes below after the four linear optical axes penetrate the middle fixed plate 3-4; the lower fixed plate 3-5 is installed on the Y-axis linear module 3-2, and the Y-axis linear module 3-2 is in turn installed on an X-axis linear module 3-1.

[0048] During implementation, the lower fixed plate 3-5 can move axially on the Y-axis linear module 3-2, and the Y-axis linear module 3-2 can in turn move axially on the X-axis linear module 3-1. In this way, the adjustment of the lower fixed plate 3-5 at any position can be realized within the overlapping moving range of the X and Y-axis linear modules, so as to ensure that the face card extraction mechanism accurately grabs the face card and correctly places it in the corresponding position of the central binding tape mechanism 7.

[0049] Furthermore, as an improvement to the present invention, an X-axis baffle 3-12 and a Y-axis baffle 3-13 are provided on the middle fixed plate 3-4, which penetrate the surface card pushing plate 3-6 to the upper fixed frame plate 3-3. The X-axis baffle 3-12, the Y-axis baffle 3-13 and the inner frame edge of the upper fixed frame plate 3-3 form a limiting channel that matches the periphery of the surface card 3-14.

[0050] During implementation, the X-axis baffle 3-12 limits the distance from the surface card 3-14 to the inner edge of the upper fixed frame plate 3-3 in the X-axis direction to prevent the surface card from loosening in the X-axis direction, and the Y-axis baffle 3-13 limits the distance from the surface card 3-14 to the inner edge of the upper fixed frame plate 3-3 in the Y-axis direction to prevent the surface card from loosening in the Y-axis direction.

[0051] Further, as an improvement to the present invention, a card sensor 3-15 is set up on one side of the upper fixed frame plate 3-4 to dynamically monitor the height of the card stacked on the card push plate 3-3. The card sensor 3-15 feeds back information to the PLC controller, and the PLC controller controls the operation of the card servo cylinder 3-11.

[0052] During implementation, the face card sensor 3-15 senses the top face card 3-14 in the limit channel. When the grabbing mechanism grabs one or more face cards, the face card sensor 3-15 cannot sense any signal, and the controller controls the face card servo cylinder 3-11 to push up until the face card sensor 3-15 senses a signal. In this way, it can be ensured that the top face card is always kept at a certain height, ensuring the normal operation of the labeling process and the grabbing process. When the face card servo cylinder 3-11 is fully extended, it means that a stack of face cards has been used up. The controller controls the face card servo cylinder 3-11 to drop to the lowest position, and manually put a new stack of face cards into the face card feeding mechanism 3.

[0053] Continue reading Figure 7 , Figure 8 , Figure 9 Further, as an improvement to the present invention, there are four thrust cylinders installed on the central hollow main board 7-13 in a centrally symmetrical form. The upper surface of each face card mold is partially concave to form a limit groove unit for placing the face card. Each limit groove unit is provided near the side groove wall with an X-axis air groove and a Y-axis air groove that penetrate from the surface to the other side surface of the face card mold to form the air groove.

[0054] During implementation, after each face card mold is merged, the X-axis air grooves are merged to form the X-axis air path, and the Y-axis air grooves are merged to form the Y-axis air path. When the face card is placed in the limit slot unit after the four face card molds are merged, the strip holes around the face card respectively match the inlet and outlet holes of the X-axis air path and the Y-axis air path.

[0055] Further, as an improvement to the present invention, the present invention also includes a finished product discharge mechanism 4, which is arranged below the hollowed-out portion in the middle of the central hollowed-out main board 7-13, and includes a discharge fixing plate 4-2, and the discharge fixing plate 4-2 is installed on the main frame 1 through a linear guide rail; four baffle plates are vertically arranged on the discharge fixing plate 4-2, namely, baffle plate 4-3, baffle plate 4-4, baffle plate 4-5, and baffle plate 4-6, and a discharge electric cylinder 4-9 is installed below the discharge fixing plate 4-2, and the telescopic rod of the discharge electric cylinder 4-9 is connected to a discharge docking platform 4-1 above.

[0056] During implementation, the baffle plate is folded vertically into an M shape, and the four baffle plates are close to each other with a gap between them at the middle section of the M shape. A discharge docking platform 4-1 is set at the gap, and the discharge docking platform 4-1 moves up and down in the gap with the discharge electric cylinder 4-9. The shape of the discharge docking platform is suitable for the face cards with the bandages. Therefore, each time a face card with the bandages is put down to the discharge docking platform 4-1, the discharge docking platform 4-1 will be lowered by a certain distance to ensure that the face cards with the bandages will not be piled up, until the discharge electric cylinder (4-9) is completely lowered, that is, the finished face cards in the discharge mechanism are fully collected, and then the stack of face cards with the bandages is manually taken out and then pushed in, and at the same time, the discharge electric cylinder (4-9) rises to the highest point to connect the next round of finished face cards.

[0057] In summary, the working principle of the present invention can be implemented as follows:

[0058] 1. The PLC controller controls the moving electric cylinder 7-10 to drive the strap conveying mechanism 7-A to move upward to the origin.

[0059] 2. The servo motor 7-9 for taking out the face card drives the four small suction cups 7-16 to move to the top of the face card feeding mechanism 3, takes out a face card with a label and rotates it to place it on the four face card molds, and then the rotating bracket 7-14 returns to the top of the face card under the drive of the servo motor to continue waiting.

[0060] 3. The mobile electric cylinder 7-10 drives the strap conveying mechanism 7-A to move downward to a certain position, so that the bottom of the Y-axis strap feeding auxiliary funnel 7-23, the X-axis strap feeding auxiliary funnel (not shown), the Y-axis suction nozzle 7-19 and the X-axis suction nozzle 7-17 are completely in contact with the upper surfaces of the four face card molds and press the face cards.

[0061] 4. The Y-axis feeding assembly line 5 and the X-axis feeding assembly line 6 start to rotate so that the two straps enter the Y-axis strap feeding auxiliary funnel 7-23 and the X-axis strap feeding auxiliary funnel (not shown) respectively. The two assembly lines are respectively equipped with pressure wheels and strap detection sensors, so that the length of the straps released can be controlled. When the two straps are released to the set length, the two assembly lines stop rotating.

[0062] 5. When the strap detection sensor controls the strap to enter the corresponding strap inlet auxiliary funnel, the Y-axis suction nozzle 7-19 and the X-axis suction nozzle 7-17 use the negative pressure fan to suck the two straps out through the Y-axis air path and the X-axis air path. When the Y-axis suction nozzle sensor 7-20 and the X-axis suction nozzle sensor 7-18 respectively sense that the strap is sucked out, the four thrust cylinders retreat, and the face card mold separates in 4 directions with the thrust cylinders.

[0063] 6. In order to prevent the surface card from falling off automatically, the auxiliary discharge suction cup sucks the surface card, and at the same time, the Y-axis pressing cylinder 7-24 and the X-axis pressing cylinder 7-25 press the ends of the two straps to prevent them from being completely sucked over.

[0064] 7. The mobile electric cylinder 7-10 drives the strap conveying mechanism 7-A to move upward to the end of the lower section. At the same time, the auxiliary discharge cylinder 7-26 extends downward until the surface card is pressed onto the docking platform 4-1 of the finished product discharge mechanism 4.

[0065] 8. The Y-axis suction nozzle 7-19 and the X-axis suction nozzle 7-17 change from suction to blowing through the reversing valve, and the sucked-out head of the strap is completely blown out. At the same time, the two downward pressure cylinders are lifted, and the Y-axis strap-in auxiliary funnel 7-23 and the X-axis strap-in auxiliary funnel (not shown) have blowing holes inside, and blow air to blow out the tail of the strap completely. Then the mobile electric cylinder 7-10 drives the strap conveying mechanism 7-A to move upward to the origin, completing the cycle.
