Description

Technical Field

[0001] This invention relates to a paper box packaging machine, and more specifically to a system for feeding paper boxes to the paper box packaging machine. Background Art

[0002] A cartoning machine is a device that inserts items to be packaged (such as medicines) along with their instructions (such as medicine instructions) into cardboard boxes. With the increasing demand for automation in the packaging industry, the operating speed of cartoning machines has increased from 200 boxes / minute for traditional equipment to over 600 boxes / minute. However, the cardboard box supply still relies on manual operation. Manual labor involves continuously stacking boxes at high speeds, resulting in high labor intensity, fatigue, and inefficiency that cannot match the machine's speed. Current technology also requires the design of dedicated pallets for different types of cardboard boxes, leading to high customization costs. Furthermore, manual stacking of boxes is prone to misalignment and tilting, affecting cartoning accuracy and yield. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention innovatively provides a carton supply system for a cartoning machine based on cable ties binding the carton.

[0004] This carton feeding system for a cartoning machine is characterized by comprising a carton transfer robot and a carton untying device. The carton transfer robot includes a robot body and a carton clamp. The carton clamp includes a mounting base, a suction nozzle, a suction nozzle lifting power source, a left clamping block, a right clamping block, and a clamping power source. The mounting base is connected to the robot body. The suction nozzle lifting power source and the clamping power source are both mounted on the mounting base. The suction nozzle is driven by the suction nozzle lifting power source. The suction nozzle lifting power source can drive the suction nozzle to move up and down. The clamping power source can drive the left clamping block to move towards or away from the right clamping block. The suction nozzle is located between the left and right clamping blocks. The carton untying device includes a placement platform and a tie. The system includes an upper suction mechanism, a cable tie cutting mechanism, a lower suction mechanism, and a lower pull mechanism. The upper suction mechanism and the lower cutting mechanism are located above the placement platform. The upper suction mechanism includes an upper suction nozzle and a power source for driving the upper suction nozzle to move up and down. The lower cutting mechanism includes a cutter and a power source for driving the cutter to perform a cutting action. The lower suction mechanism and the lower pull mechanism are located below the placement platform. The lower suction mechanism includes a lower suction nozzle and a power source for driving the lower suction nozzle to move up and down. The placement platform has a discharge port, and the lower suction nozzle can pass upward through the discharge port. The lower pull mechanism includes a pull rod and a power source for driving the pull rod to perform a pulling action.

[0005] Below the placement platform is a cable tie conveying mechanism, which includes two conveying units, left and right. The pull rod can enter between the two conveying units. Each conveying unit includes a conveying seat, a conveyor belt, upper and lower conveyor pulleys, and a power source. The upper and lower conveyor pulleys are mounted on the conveying seat, and the conveyor belt is wound around the upper and lower conveyor pulleys. The power source is mounted on the conveying seat and is driven by the conveyor pulleys. The conveying seat is slidably mounted on a horizontal guide rail, and the two conveying units are driven by the clamping power source that drives the relative movement of the two conveying units.

[0006] The placement platform is equipped with a rotatable transmission screw. A first nut is connected to the conveyor seat of one of the conveying units, and the first nut is threadedly connected to the transmission screw in the forward direction. A second nut is connected to the conveyor seat of the other conveying unit, and the second nut is threadedly connected to the transmission screw in the reverse direction. The transmission screw is connected to the clamping power source.

[0007] The cable tie suction mechanism is provided in two parts, one on the left and one on the right. One cable tie suction mechanism is located on the outside of one conveying unit, and the other cable tie suction mechanism is located on the outside of another conveying unit.

[0008] The pull-down rod is connected to a translational force source that drives the pull-down rod to move back and forth. The pull-down force source can drive the translational force source and the pull-down rod to move up and down together.

[0009] Both the cable tie suction mechanism and the cable tie cutting mechanism are mounted on the movable frame. The movable frame is slidably mounted on the guide rail via a slider. The movable frame is connected to the power source that drives the movable frame to move.

[0010] The cutter includes a fixed cutter and a movable cutter. The cutter power source can drive the fixed cutter and the movable cutter to tangent. The fixed cutter is connected to the fixed cutter power source that drives the fixed cutter to move back and forth. The movable cutter is located above the fixed cutter. The cutter power source can drive the movable cutter to move up and down. The suction nozzle on the cable tie is located on one side of the movable cutter.

[0011] The device includes a paper box storage unit, which includes a paper box storage unit. A paper box support mechanism is provided on one side of the paper box storage unit. The paper box support mechanism includes a paper box support rod, a telescopic power source, a movable seat, and a material support power source. The paper box support rod is driven to extend and retract forward and backward. The paper box support rod is used to block the rear side of the paper box. The telescopic power source is mounted on the movable seat, which is driven to move back and forth along the paper box feeding direction of the paper box storage unit.

[0012] A rotating seat is rotatably mounted on the movable seat. The telescopic power source and the cardboard box handle are both located on the rotating seat. The rotating seat can rotate forward under the action of a spring, causing the cardboard box handle to tend to push forward. A proximity switch is provided on the movable seat. The rotating seat can rotate backward to compress the spring and act on the proximity switch. The proximity switch is connected to the control system. The control system can control the output of the material handling power source.

[0013] The mounting base is equipped with a pressing power source, which is connected to the pressing plate. The pressing power source can drive the pressing plate to move up and down. The pressing plate is located on the side where the right clamp is located.

[0014] The carton supply system for a cartoning machine provided by the present invention can automatically supply cartons, thereby reducing labor intensity, increasing the carton placement speed, and matching the high-speed packaging requirements of the cartoning machine.

Detailed Implementation

[0016] like Figure 1 As shown, the cardboard box supply system first moves the cardboard box H, which is bundled with cable ties H1, to the cardboard box cable tie removal device C via the cardboard box transfer robot M (the cardboard box is flat and multiple cardboard boxes are bundled together with cable ties). Then, the cardboard box transfer robot M moves the cardboard box H, which has had its cable ties removed from H1, to the cardboard box storage device N. The cardboard box storage device N then conveys the cardboard box forward. After being sucked up by the suction robot, the box can be automatically opened for packaging items.

[0017] like Figure 9 As shown, this cardboard box transfer robot M includes a robot body M1 and a cardboard box clamp M2. The cardboard box clamp M2 is mounted on the robot body M1. The cardboard box clamp M2 can both hold the cable ties H1 that bind the cardboard boxes H and transfer the cardboard boxes one by one from the stacking area to the cardboard box cable tie removal device C. After the cable ties H1 are removed by the cardboard box cable tie removal device C, the cardboard boxes H are then transferred to the cardboard box storage device N.

[0018] like Figure 9 and Figure 10 As shown, the paper box clamp M2 includes a mounting base M20, a suction nozzle M21, a suction nozzle lifting power source M22, a left clamping block M23, a right clamping block M24, and a clamping power source M25. The mounting base M20 is connected to the main body M1 of the robot arm. The suction nozzle lifting power source M22 and the clamping power source M25 are both mounted on the mounting base M20. The suction nozzle M21 is driven by the suction nozzle lifting power source M22, which can drive the suction nozzle M21 to move up and down. The left clamping block M23 is driven by the clamping power source M25, which can drive the left clamping block M23 to move closer to or away from the right clamping block M24. The suction nozzle M21 is located between the left clamping block M23 and the right clamping block M24.

[0019] During operation, the robotic arm body M1, carrying the cardboard box clamp M2, arrives at the cardboard box stacking area. First, the suction nozzle lifting power source M22 drives the suction belt nozzle M21 to move downward. Figure 10 As shown, the suction nozzle M21 picks up the cable tie H1 binding the cardboard box H, transferring the box from the stacking area to the cable tie removal device C. After the cable tie removal device C removes the cable tie H1, the suction nozzle lifting power source M22 drives the suction nozzle M21 to move upward, creating space between the left clamping block M23 and the right clamping block M24. Then, the clamping power source M25 drives the left clamping block M23 to move closer to the right clamping block M24, so that the left clamping block M23 and the right clamping block M24 can clamp the cardboard box H. Figure 11As shown, the cardboard box H is transferred to the cardboard box storage device N. It is worth mentioning that at the cardboard box stacking area, all the cardboard boxes are stacked together with almost no gaps between each bundle, making it difficult to clamp them. The only way to deliver the cardboard box H to the cardboard box tying device C is to use the suction nozzle M21 to suck up the cable tie H1 binding the cardboard box H from directly above.

[0020] When the left clamping block M23 and the right clamping block M24 clamp the paper box H and transfer it to the paper box storage device N, the newly placed paper box H and the already placed paper boxes H on the paper box storage device N will be close together. This means the right clamping block M24 will be sandwiched between the paper boxes H. When the paper box clamp M2 places the paper box H and lifts it upwards, the right clamping block M24 may lift the paper box H closest to it due to friction, affecting the placement of the paper box. To solve this problem, a pressing power source M27 is installed on the mounting base M20. This pressing power source M27 is connected to a pressing plate M28, which is located on the side where the right clamping block M24 is located. When the paper box clamp M2 is lifted, the pressing power source M27 drives the pressing plate M28 to move downwards, pressing the paper box H downwards. This prevents the paper box H from being lifted upwards when the left clamping block M23 and the right clamping block M24 are lifted upwards, ensuring that the paper box H is placed stably.

[0021] like Figure 9 As shown, there are two sets of suction nozzles M21 and suction nozzle lifting power source M22. The two sets of suction nozzles M21 can improve the stability of suction and prevent the paper box H from falling.

[0022] like Figure 9 As shown, there are two right clamping blocks M24 on the left and right, and one left clamping block M23. The three clamping blocks can stably clamp the paper box H. A space is provided on one side of the left clamping block M23 for the paper box support rod N2 on the paper box storage device N to extend into and block the paper box H to prevent it from tipping over after it is placed.

[0023] like Figure 10 As shown, a distance detection photoelectric sensor M26 is installed on the mounting base M20. The distance detection photoelectric sensor M26 is connected to the control system, which can control the suction nozzle lifting power source M22 to move. When the cardboard box clamp M2 moves to the work position above the cardboard box stack, after the distance detection photoelectric sensor M26 confirms the distance, the control system controls the suction nozzle lifting power source M22 to move. The lifting power source M22 drives the suction nozzle M21 to move down and suck up the cable tie H1 that is binding the cardboard box H.

[0024] Both the nozzle lifting power source M22 and the clamping power source M25 are cylinders, but they can also be motors.

[0025] After the cardboard box H with cable tie H1 is sent to the cardboard box cable tie removal device C, the device C removes the cable tie H1. For example... Figure 2As shown, this cardboard box cable tie removal device C includes a placement platform C1, and a cable tie suction mechanism C2 and a cable tie cutting mechanism C3 are provided above the placement platform C1. Figure 3 As shown, the cable tie suction mechanism C2 includes a cable tie suction nozzle C20 and a suction nozzle power source C21 that drives the cable tie suction nozzle C20 to move up and down; the cable tie cutting mechanism C3 includes a cutter C30 and a cutter power source (not shown) that drives the cutter C30 to perform a cutting action; as shown Figure 4 As shown, a cable tie suction mechanism C4 and a cable tie pull-down mechanism C5 are provided below the placement platform C1, as follows: Figure 7 As shown, the cable tie suction mechanism C4 includes a cable tie suction nozzle C40 and a suction nozzle power source C41 that drives the cable tie suction nozzle C40 to move up and down. Figure 4 As shown, the placement platform C1 has a discharge port C10, and the cable tie suction nozzle C40 can pass upward through the discharge port C10; as Figure 4 As shown, the cable tie pull-down mechanism C5 includes a pull-down rod C50 and a pull-down power source C51 that drives the pull-down rod C50 to perform a pull-down action.

[0026] The working principle of this cardboard box cable tie removal device C is as follows: The cardboard box transfer robot M places the cardboard box H with cable tie H1 onto the placement platform C1. The cardboard box H is above the feed inlet C10. At this time, the cable tie suction nozzle C20 of the cable tie suction mechanism C2 suctions the cable tie H1 from above. Then, the suction nozzle power source C21 drives the cable tie suction nozzle C20 to move upward, thus suctioning up the upper part of the cable tie H1. Figure 3 As shown, the upper part of the cable tie H1 is thus separated from the upper surface of the cardboard box H; then the cable tie cutting mechanism C3 starts working, and the cutter power source drives the cutter C30 to perform a cutting action, cutting off the upper part of the cable tie H1, as shown. Figure 5 As shown; then the cable tie suction mechanism C4 starts working, and the suction nozzle power source C41 drives the cable tie suction nozzle C40 to move upward, as shown. Figure 6 As shown, the cable tie suction nozzle C40 passes through the discharge port C10 of the placement platform C1 and sucks up the bottom of the cable tie H1. The suction nozzle power source C41 then drives the cable tie suction nozzle C40 to move downward, sucking the cable tie H1 down. Since the cable tie H1 has been cut, the downward-moving cable tie H1 is sucked down (the bottom of the cable tie H1 is below the placement platform C1). Then the cable tie pull-down mechanism C5 starts to work. The pull-down power source C51 drives the pull-down rod C50 to move down, and the pull-down rod C50 pulls the cable tie H1 down, so the cable tie H1 falls down, thus completing the removal of the cable tie H1.

[0027] Pulling cable tie H1 down using lever C50 will cause it to fall in a rather scattered manner. To ensure cable tie H1 falls smoothly into the collection bin below, as follows... Figure 5 and Figure 6As shown, a cable tie conveying mechanism C6 is provided below the placement platform C1. This mechanism C6 includes two conveying units C60, one on the left and one on the right, and a pull rod C50 can enter between the two conveying units C60. Figure 6 As shown, each conveying unit C60 includes a conveying seat C601, a conveyor belt C603, two upper and lower conveyor pulleys C602, and a conveying power source C604. The two upper and lower conveyor pulleys C602 are mounted on the conveying seat C601, and the conveyor belt C603 is wound around the two upper and lower conveyor pulleys C602. The conveying power source C604 is mounted on the conveying seat C601 and is connected to the conveyor pulleys C602 in a driving connection. In addition, the conveying seat C604 is slidably mounted on a horizontal guide rail C64, and the two conveying units C60 are connected to the clamping power source C63 that drives the two conveying units C60 to move relative to each other.

[0028] When cable tie H1 is pulled down by the pull rod C50, cable tie H1 is positioned between the two conveying units C60. The pull rod C50 retracts, and the clamping power source C63 drives the two conveying units C60 to move closer together on the horizontal guide rail C64. In this way, the two conveyor belts C603 clamp the cable tie H1. Then, the conveying power source C604 drives the conveyor belts C603 to move. Through the transmission of the two conveyor belts C603, the cable tie H1 is smoothly conveyed downwards, and the cable tie H1 falls stably into the collection bucket below.

[0029] In order for a single clamping power source C63 to drive two conveying units C60 to move simultaneously, such as Figure 6 As shown, a rotatable transmission screw C65 is provided below the placement platform C1. A first nut C62 is connected to the conveyor seat C601 of one conveying unit C60, and the first nut C62 is threadedly connected to the transmission screw C65 in the forward direction. A second nut C66 is connected to the conveyor seat of the other conveying unit, and the second nut C66 is threadedly connected to the transmission screw C65 in the reverse direction. The transmission screw C65 is connected to the clamping power source C63. With this structure, one clamping power source C63 drives the transmission screw C65, which in turn drives the two conveying units C60 to move synchronously relative to each other, saving costs.

[0030] In order to stably pull the cable tie H1 downwards, such as Figure 4 As shown, there are two cable tie suction mechanisms C4, one on the left and one on the right. One cable tie suction mechanism C4 is located outside one conveying unit C60, and the other cable tie suction mechanism C4 is located outside another conveying unit C60. The two cable tie suction mechanisms C4 can stably suck the cable tie H1 downwards and form a large notch, which facilitates the insertion of the pull rod C50.

[0031] like Figure 4As shown, the pull rod C50 is connected to the translational force source C52, which drives the pull rod C50 to move back and forth. The pull-down power source C51 can drive the translational force source C52 and the pull rod C50 to move up and down together. When the cable tie H1 is sucked down by the cable tie suction mechanism C4, the translational force source C52 drives the pull rod C50 to insert into the inner circle of the cable tie H1. Then, the pull-down power source C51 drives the translational force source C52 and the pull rod C50 to move down together, so that the pull rod C50 can pull the cable tie H1 down. Of course, the pull-down power source C51 can also directly drive the pull rod C50 to move diagonally downward, so that the pull rod C50 enters the inner circle of the cable tie H1 and pulls the cable tie H1 down.

[0032] In order to free up space, the cardboard box transfer robot M places the cardboard box H with cable ties H1 into the corresponding position on the placement platform C1, such as... Figure 2 As shown, the cable tie suction mechanism C2 and the cable tie cutting mechanism C3 are both mounted on the movable frame C7. The movable frame C7 is slidably mounted on the guide rail C71 via a slider C70, and the movable frame C7 is connected to the movable frame power source C8 that drives the movable frame C7 to move. When the cardboard box H has removed the cable tie H1, the movable frame power source C8 drives the movable frame C7 to move away with the cable tie suction mechanism C2 and the cable tie cutting mechanism C3. When the cardboard box transfer robot M delivers the cardboard box H with the cable tie H1, there is space to place a new stack of cardboard boxes H into the corresponding position on the placement platform C1. After the cardboard box H is placed, the movable frame power source C8 drives the movable frame C7 to reset with the cable tie suction mechanism C2 and the cable tie cutting mechanism C3, and the removal of cable ties H1 begins again.

[0033] To align the cardboard boxes H so they can be easily transferred to the robotic arm M for gripping. For example... Figure 2 and Figure 3 As shown, a paper box sorting mechanism C9 is provided on the placement platform C1. This mechanism C9 includes a left push plate C90, a right push plate C91, and a side push plate C92. The left push plate C90 is connected to a left push plate power source C93 that drives its left and right movement. The right push plate C91 is connected to a right push plate power source C94 that drives its left and right movement. The side push plate C92 is connected to a side push plate power source C95 that drives its back and forth movement. Through the tapping action of the left push plate C90, right push plate C91, and side push plate C92, the paper boxes H1 after the cable ties H1 are removed are more neatly arranged, making it easier for the paper box transfer robot M to grip them and place them neatly on the paper box storage device N.

[0034] like Figure 8 As shown, the cutter C30 includes a fixed cutter C301 and a movable cutter C302. The cutter's power source can drive the fixed cutter C301 and the movable cutter C302 to cut each other (similar to scissors cutting). In this way, the fixed cutter C301 and the movable cutter C302 can cut the cable tie H1.

[0035] In order for the cable tie H1 to enter between the fixed cutter C301 and the movable cutter C302, as follows: Figure 8 As shown, the fixed cutter C301 is connected to the fixed cutter power source C303, which drives the fixed cutter C301 to move back and forth. The movable cutter C302 is located above the fixed cutter C301. The cutter power source can drive the movable cutter C302 to move up and down, while the cable tie suction nozzle C20 is located to one side of the movable cutter C302. When the cable tie H1 is picked up by the cable tie suction nozzle C20, the upper part of the cable tie H1 is below the movable cutter C302. Then, the fixed cutter power source C303 drives the fixed cutter C301 to move forward, so that the upper part of the cable tie H1 is above the fixed cutter C301. Thus, the upper part of the cable tie H1 is between the fixed cutter C301 and the movable cutter C302. Finally, the cutter power source can drive the movable cutter C302 to move downward, so that the fixed cutter C301 and the movable cutter C302 can cut the cable tie H1 tangentially.

[0036] like Figure 1 As shown, after the cable tie H1 is removed from cardboard box H, the cardboard box transfer robot M delivers cardboard box H (which is not opened and is flat) to the cardboard box storage device N. Figure 12 As shown, this paper box storage device N includes a paper box storage compartment N1 (composed of a base plate N13 and a side plate N14). To facilitate the placement of paper boxes H by the paper box transfer robot M, as shown... Figure 12 and Figure 13 As shown, a paper box support mechanism is provided on one side of the paper box compartment N1. This paper box support mechanism includes a paper box support rod N2, a telescopic power source N3, a movable seat N4, and a material support power source N5. The paper box support rod N2 is connected to the telescopic power source N3, and the telescopic power source N3 can drive the paper box support rod N2 to extend and retract back and forth. Figure 12 (In the X-axis direction), the carton support rod N2 is used to block the rear side of the carton; while the telescopic power source N3 is mounted on the movable seat N4, which is connected to the material support power source N5. The material support power source N5 can drive the movable seat N4 to move back and forth along the feeding direction of the carton compartment N1. Figure 12 (Y-axis direction in the text).

[0037] During operation, the cardboard box transfer robot M places a stack of cardboard boxes H into the cardboard box compartment N1. The newly placed cardboard box H rests against the back of the already placed cardboard box H. After the newly placed cardboard box H is in place, the telescopic power source N3 drives the cardboard box support rod N2 to retract. The cardboard box support rod N2 no longer supports the back of the already placed cardboard box H. Then, the material handling power source N5 drives the moving seat N4 to move backward. The moving seat N4 moves backward along with the cardboard box support rod N2 and the telescopic power source N3. When it reaches the back of the newly placed cardboard box H, the moving seat N4 stops, and the telescopic power source N3 drives the cardboard box support rod N2 to extend forward and block the back of the newly placed cardboard box H. In this way, the cardboard box support rod N2 can hold the cardboard box H and prevent the cardboard box H from tipping over backward.

[0038] To ensure that the cardboard box support rod N2 can exert a certain force on the rear side of the cardboard box H, and to ensure that the support rod N2 can act firmly on the rear side of the cardboard box H, keeping the cardboard box H upright (if the cardboard box H tilts backward, it will affect the subsequent placement of cardboard boxes H), as follows... Figure 13 As shown, a rotating seat N10 is rotatably mounted on the movable seat N4, and both the telescopic power source N3 and the cardboard box handle N2 are located on the rotating seat N10. The rotating seat N10 can rotate forward under the action of the spring N11, causing the cardboard box handle N2 to tend to push forward. Figure 12 (In the Y-axis direction), a proximity switch N6 is provided on the movable seat N4. The rotating seat N10 can rotate backward to compress the spring N11 and act on the proximity switch N6. The proximity switch N6 is connected to the control system signal, and the control system can control the output of the material support power source N5. When the paper box support rod N2 is tightly acting on the rear side of the paper box H, the rotating seat N10 can rotate backward to compress the spring N11. When the rotating seat N10 abuts against the proximity switch N6, the proximity switch N6 receives a signal, and the control system controls the material support power source N5 to stop outputting, so the rotating seat N10 stops at that position. As the paper box H is continuously consumed, the rear side of the paper box H no longer exerts force on the paper box support rod N2. Under the action of the spring N11, the rotating seat N10 rotates forward, so the rotating seat N10 no longer acts on the proximity switch N6. The proximity switch N6 transmits a signal to the control system, and the control system controls the output of the material support power source N5, allowing the rotating seat N10 to move forward until the paper box support rod N2 is tightly acting on the rear side of the paper box H again. This cycle ensures that the cardboard box H remains vertical and does not tilt backward.

[0039] like Figure 13 As shown, the cardboard box compartment N1 includes a base N13 and a side plate N14. A conveyor belt N12 is mounted on the base N13 and is connected to a feeding power source. Cardboard boxes H are placed on the base N13, and driven by the feeding power source, the conveyor belt N12 moves the cardboard boxes H forward.

[0040] like Figure 12As shown, a paper box tapping mechanism is provided on the paper box compartment N1. The paper box tapping mechanism includes a tapping plate N8 and a tapping plate power source N9 that drives the tapping plate N8. The tapping plate N8 is located on the opposite side of the side plate N14, and the tapping plate N8 can tap the side of the paper box. The paper box H is placed on the base N13 and rests against one side of the side plate N14. The tapping plate power source N9 drives the tapping plate N8 to tap the paper box H towards the side of the side plate N14, so that the paper box H is aligned with the side plate N14 as a reference, ensuring that the paper box H is neat.

[0041] Finally, it's worth mentioning that the telescopic power source N3 is an electric actuator, motor, cylinder, or hydraulic cylinder. The material handling power source N5 is an electric cylinder, motor, cylinder, or hydraulic cylinder. When the telescopic power source N3 is a cylinder, the cardboard box handle N2 can be a piston rod integrated with the cylinder.
