Description

Technical Field

[0001] The present application relates to the technical field of office equipment, and more specifically to a binding machine and a control method thereof. Background Art

[0002] Binding machines are mainly used for binding documents, bills and vouchers, etc. The binding machine uses a drill to drill a circular binding hole on the edge of the object to be bound, and then uses a hot riveting mechanism to hot-press the upper and lower ends of the rivet tube inserted into the binding hole into a rivet tube head to achieve rivet tube binding. The binding machine generally includes a punching mechanism and a riveting mechanism. The punching mechanism is raised and lowered to drill holes in the object to be bound, and the riveting mechanism can insert the rivet tube into the above drilled hole. Therefore, with the use of the binding machine, the remaining rivet tube in the binding machine gradually decreases, and the total length of the rivet tube gradually decreases. When the remaining length of the rivet tube is not enough to meet the thickness of the object to be bound, that is, after drilling the object to be bound, the remaining rivet tube cannot complete the binding task, affecting normal binding, and even causing waste of the object to be bound or the rivet tube. In view of the above problems, a Chinese invention patent with publication number: CN113173020A discloses a binding method and a binding machine, wherein the binding method is implemented by a binding machine; the binding method comprises: placing objects to be bound on a workbench, measuring the length of the hose required for binding the objects to be bound by a measuring device as a first length; storing the remaining length of the hose in the binding machine as a second length; comparing the first length with the second length: if the first length is greater than the second length, the interactive device prompts the user, and the binding device does not start; if the first length is less than the second length, the binding device starts; the binding machine uses the above binding method; in the technical solution, by comparing the first length with ... user prompts the user, and the binding device does not start; if the first length is less than the second length, the binding device starts; the binding machine uses the above binding method; in the technical solution, by comparing the first length with the second length, the user prompts the user, and the binding device does not start; if the first length is less than the second length, the binding device starts; the binding machine uses the above binding method; in the technical solution, by comparing the first length with the second length, the user prompts the user, and the binding device does not start; if the first length is less than the second length, the binding device starts; the binding machine The remaining amount of the hose is detected, and binding is only carried out when the remaining amount of the hose is sufficient, thereby avoiding waste of the material to be bound or the hose. However, this technical solution can only solve the problem that only one hose is stored in the binding machine, and some users will continuously put multiple hoses in during use. When multiple hoses are in the binding machine at the same time, the multiple hoses are spliced ​​front and back. Even if the remaining amount of the first hose put in is insufficient, it is difficult to measure. As a result, after the front and rear hoses are spliced ​​together, the material to be bound is riveted, and the riveting reliability of the spliced ​​tubes is low, and it is easy to fall off. It is also possible that only the hose with insufficient remaining amount is used for binding, resulting in the situation that half of the material to be bound is riveted and cannot be completed. Summary of the invention

[0003] The technical problem to be solved by the present application is to provide a binding machine and a control method thereof, wherein the binding machine conveys a rivet tube in a first conduit along a first direction through a tube feeding device, and an additional tube discharging device is provided to convey the rivet tube in a second conduit along a second direction, thereby separating the rivet tube in the first conduit and the rivet tube in the second conduit from each other, avoiding the formation of spliced ​​rivet tubes after the front and rear rivet tubes sequentially enter the first conduit, thereby improving the riveting efficiency and reliability.

[0004] The present application provides a binding machine, comprising a frame, a tube feeding device installed on the frame, the tube feeding device comprising a first guide tube and a first driving mechanism, the first guide tube being used for placing a rivet tube, the first driving mechanism being used for driving the rivet tube in the first guide tube to move along a first direction to achieve feeding; a tube arranging device is also installed on the frame, the tube arranging device comprising a second guide tube and a second driving mechanism, the second guide tube being connected to the first guide tube, the second driving mechanism being used for driving the rivet tube in the second guide tube to move along a second direction, the tube arranging device being located in the second direction of the tube feeding device, the rivet tube in the second guide tube being separated from the rivet tube in the first guide tube by moving along the second direction to be limited in the second guide tube.

[0005] In the technical solution, the riveting tube is conveyed to the riveting mechanism by a tube conveying device, the riveting tube is placed in the first conduit, and the riveting tube is driven to move in the first direction by the first driving mechanism to realize the conveying. By installing a tube discharging device on the second direction of the tube conveying device, the riveting tube is placed in the second conduit, and the riveting tube is driven to move in the second direction by the second driving mechanism to be limited in the second conduit. The first direction is opposite to the second direction, thereby preventing the riveting tube in the second conduit from entering the first conduit along the first direction. When only one riveting tube is placed in the second conduit, the second driving mechanism cannot drive the riveting tube to move in the second direction by controlling the tube discharging device to stop or reverse operation, thereby enabling the riveting tube to enter the first conduit through the second conduit along the first direction. After the riveting tube enters the first conduit, the first driving mechanism The first and second rivet tubes are placed in the second conduit one after the other, and the first rivet tube enters the first conduit through the aforementioned steps. When the second rivet tube enters the second conduit, the pipe arrangement device operates normally to enable the second driving mechanism to drive the second rivet tube to move in the second direction, so that the second rivet tube cannot enter the first conduit along the first direction. The second rivet tube is limited in the second conduit, thereby separating the first rivet tube in the first conduit and the second rivet tube in the second conduit. The first and second in this application are only used to indicate the order in which two adjacent rivet tubes enter the first conduit and the second conduit. The first rivet tube that enters is the first rivet tube, and the second rivet tube that enters is the second rivet tube. The following will not be repeated, so as to avoid the formation of spliced ​​rivet tubes after the two rivet tubes enter the first conduit one after another, thereby improving the riveting efficiency and reliability.

[0006] As an improvement, the second drive mechanism is electrically connected to a controller, and the second drive mechanism can drive the riveted tube in the second conduit to move in the first direction or the second direction through the controller. In this technical solution, the second drive mechanism is electrically connected to the controller, and the controller can control the second drive mechanism to drive the riveted tube to move in the first direction or the second direction. When the first riveted tube is placed in the second conduit, the controller controls the second drive mechanism to first convey the first riveted tube in the first direction, so that the first riveted tube can enter the first conduit along the first direction. When the second riveted tube is placed in the second conduit, the controller controls the second drive mechanism to convey the second riveted tube in the second direction, so that the second riveted tube is limited in the second conduit, thereby being separated from the first riveted tube. The running direction of the second drive mechanism is controlled by the controller to improve the riveted tube conveying efficiency, avoid the splicing of the front and rear riveted tubes, thereby improving the riveting efficiency and reliability, meeting more production and use requirements, and improving the intelligence of the whole machine.

[0007] As an improvement, the second driving mechanism includes a second pipe delivery wheel and a second motor. The controller drives the second pipe delivery wheel to rotate bidirectionally through the second motor. The second pipe delivery wheel delivers or blocks the riveted tube in the second conduit through bidirectional rotation. In this technical solution, a second driving mechanism is set to drive the second pipe delivery wheel to rotate through the second motor, so that the second pipe delivery wheel can drive the riveted tube in the second conduit to move. The riveted tube is placed in the second conduit, and the output shaft of the second motor is connected to the second pipe delivery wheel to drive the second pipe delivery wheel to rotate forward or reversely. The second pipe delivery wheel can drive the riveted tube in the second conduit into the first conduit or block the riveted tube in the second conduit from entering the first conduit through bidirectional rotation, thereby improving the riveting efficiency and reliability.

[0008] As an improvement, the tube delivery device is connected to a tube inspection mechanism, which is electrically connected to the controller. The tube inspection mechanism is used to detect whether there is a riveted tube in the first conduit and transmit the detection signal to the controller, and the controller controls the bidirectional rotation of the second tube delivery wheel through the detection signal. In the present technical solution, a tube delivery device is provided to be connected to the tube inspection mechanism, which detects whether there is a riveted tube in the first conduit through the tube inspection mechanism, and the tube inspection mechanism is electrically connected to the controller. The tube inspection mechanism can transmit the detection signal of whether there is a riveted tube in the first conduit to the controller, and the controller controls the bidirectional rotation of the second tube delivery wheel according to the detection signal. When the tube inspection component detects that there is no riveted tube in the first conduit, the tube inspection component transmits the detection signal to the controller, and the controller controls the second tube delivery wheel to rotate in a first direction so as to be able to transport the riveted tube in the second conduit along the first direction, so that the riveted tube in the second conduit enters the first conduit. When the tube inspection component detects that there is a riveted tube in the first conduit, the tube inspection component transmits the detection signal to the controller. The controller controls the rotation of the second tube delivery wheel so as to be able to transport the riveted tube in the second conduit along the first direction, so that the riveted tube in the second conduit enters the first conduit. The detection signal is transmitted to the controller, and the controller controls the second tube-feeding wheel to rotate in the opposite direction so as to be able to transmit the riveted tube in the second conduit along the second direction, so that the riveted tube in the second conduit cannot enter the first conduit, thereby separating the riveted tube in the first conduit from the riveted tube in the second conduit. When the riveted tube in the first conduit is completely separated from the first conduit, the tube-detecting component detects that there is no riveted tube in the first conduit and transmits the detection signal to the controller, and the controller controls the second tube-feeding wheel to rotate so that the riveted tube in the second conduit can be transmitted to the first conduit along the first direction, and the above steps are repeated, thereby avoiding the front and rear riveted tubes from being spliced, improving the riveting efficiency and reliability, and improving the intelligence of the whole machine.

[0009] As an improvement, the first direction is the direction of gravity, and the second direction is opposite to the direction of gravity. In this technical solution, the first direction is set as the direction of gravity, and the second direction is opposite to the direction of gravity, that is, the pipe arrangement device and the pipe delivery device are distributed up and down, so that the riveted pipe in the first conduit is not only affected by the conveying action of the first drive mechanism but also by its own gravity, thereby improving the pipe delivery efficiency of the pipe delivery device. On the other hand, the riveted pipe in the second conduit can also enter the first conduit under the action of its own gravity, and when it is necessary to separate the front and rear riveted pipes, the riveted pipe in the second conduit stops falling due to the offset of gravity and the conveying force of the second drive mechanism along the second direction, and is thus limited in the second conduit, thereby avoiding the splicing of the front and rear riveted pipes, improving the riveting efficiency and reliability, and improving the intelligence of the whole machine. The upper and lower installation distribution method is simple and saves installation space.

[0010] As an improvement, the driving force of the first driving mechanism is greater than or equal to the driving force of the second driving mechanism. In this technical solution, when a single riveted tube enters the second conduit, the inspection mechanism first detects that there is no riveted tube in the first conduit, and the controller controls the second tube delivery wheel to rotate to deliver the riveted tube to the first conduit along the first direction. At this time, the inspection mechanism detects that there is a riveted tube in the first conduit, and the controller controls the second tube delivery wheel to rotate in the opposite direction to deliver the riveted tube along the second direction. The riveted tube exists in the first conduit and the second conduit at the same time. By setting the driving force of the first driving mechanism to be greater than or equal to the driving force of the second driving mechanism, that is, the force in the first direction on the riveted tube is greater than the force in the second direction, the riveted tube can be delivered in the first direction. In this process, the second tube delivery wheel keeps delivering the riveted tube in the second direction. Even if a new riveted tube is subsequently placed, the new riveted tube can be prevented from entering the first conduit, thereby avoiding the splicing of the front and rear riveted tubes, improving the riveting efficiency and reliability, and improving the intelligence and reliability of the whole machine.

[0011] As an improvement, the first driving mechanism is provided with a first pipe delivery wheel and a first motor, and the first motor drives the first pipe delivery wheel to rotate so that the riveted pipe in the first conduit moves along the first direction. In this technical solution, the first driving mechanism is provided to drive the first pipe delivery wheel to rotate through the first motor, so that the first pipe delivery wheel can drive the riveted pipe in the first conduit to move, and the riveted pipe enters the first conduit, and the output shaft of the first motor is connected to the first pipe delivery wheel to drive the first pipe delivery wheel to rotate. The first pipe delivery wheel can drive the riveted pipe in the first conduit to move along the first direction by rotating to complete the transportation, achieve the purpose of pipe delivery, and improve the efficiency of pipe delivery.

[0012] As an improvement, the pipe delivery device is provided with a first roller opposite to the first pipe delivery wheel, and the first roller cooperates with the first pipe delivery wheel to move the riveted pipe in the first conduit along the first direction. In this technical solution, by adding a first roller in the pipe delivery device, the first roller and the first pipe delivery wheel are relatively distributed, one side of the riveted pipe in the first conduit abuts against the first roller, and the other side abuts against the first pipe delivery wheel, so that the first roller can rotate synchronously when the first pipe delivery wheel rotates to deliver the riveted pipe, and the first roller cooperates with the first pipe delivery wheel to deliver the riveted pipe, so as to avoid the riveted pipe abutting against the inner wall of the first conduit to increase the friction force, thereby improving the pipe delivery efficiency.

[0013] The present application may also provide a control method for a binding machine, comprising a frame, a tube feeding device and a tube arranging device are installed on the frame, the tube feeding device comprises a first guide tube and a first driving mechanism, and the tube arranging device comprises a second guide tube and a second driving mechanism; and further comprising the following steps:

[0014] S1, when the first riveted tube passes through the second conduit and enters the first conduit, the first driving mechanism drives the first riveted tube to move in the first direction, and the second driving mechanism drives the first riveted tube to move in the second direction, and the driving force of the first driving mechanism is greater than the driving force of the second driving mechanism so that the first riveted tube moves in the first direction;

[0015] S2. When the preceding riveted tube is separated from the second guide tube and the following riveted tube enters the second guide tube, the first driving mechanism drives the preceding riveted tube to continue to move in the first direction, and the second driving mechanism drives the following riveted tube to move in the second direction to reversely transport the following riveted tube, so that the following riveted tube is confined in the second guide tube and is separated from the preceding riveted tube.

[0016] In the technical solution, the riveting tube is conveyed to the riveting mechanism by the tube conveying device, the riveting tube is placed in the first conduit, and the riveting tube is driven to move in the first direction by the first driving mechanism to realize the conveying, and the tube arrangement device is installed on the second direction of the tube conveying device, the riveting tube is placed in the second conduit, and the riveting tube is driven to move in the second direction by the second driving mechanism to be limited in the second conduit, and the first direction is opposite to the second direction, thereby preventing the riveting tube in the second conduit from entering the first conduit along the first direction, avoiding the formation of spliced ​​riveting tubes after the front and rear riveting tubes enter the first conduit in sequence, and improving the riveting efficiency and reliability;

[0017] When the first riveted tube passes through the second conduit and enters the first conduit, the first riveted tube exists in the first conduit and the second conduit at the same time, the first driving mechanism drives the first riveted tube to move in the first direction, and the second driving mechanism drives the first riveted tube to move in the second direction, the driving force of the first driving mechanism is greater than or equal to the driving force of the second driving mechanism, that is, the force in the first direction applied to the first riveted tube is greater than the force in the second direction, so that the first riveted tube can be transported in the first direction; when the first riveted tube leaves the second conduit and the subsequent riveted tube enters the second conduit, the first riveted tube is located in the first conduit, the first driving mechanism drives the first riveted tube to continue to move in the first direction, and the second driving mechanism drives the subsequent riveted tube to move in the second direction to reversely transport the subsequent riveted tube, so that the subsequent riveted tube is limited in the second conduit, the first riveted tube in the first conduit and the subsequent riveted tube in the second conduit are separated, so as to avoid the formation of spliced ​​riveted tubes after the front and rear riveted tubes enter the first conduit in sequence, thereby improving the riveting efficiency and reliability.

[0018] As an improvement, the tube delivery device is connected with a tube inspection mechanism, and the second drive mechanism and the tube inspection mechanism are both electrically connected to the controller; in step S1, the tube inspection mechanism detects that there is a prior riveted tube in the first conduit, and the tube inspection mechanism transmits the detection signal to the controller, and the controller controls the second drive mechanism to drive the prior riveted tube to move in the second direction. In this technical solution, the tube inspection mechanism detects whether there is a riveted tube in the first conduit, and the second drive mechanism and the tube inspection mechanism are both electrically connected to the controller. The tube inspection mechanism can transmit the detection signal of whether there is a riveted tube in the first conduit to the controller, and the controller controls the second tube delivery wheel to rotate in both directions according to the detection signal. In step S1, the prior riveted tube passes through the second conduit and enters the first conduit. The tube inspection mechanism detects that there is a riveted tube in the first conduit, and the tube inspection mechanism transmits the detection signal to the controller, and the controller controls the second drive mechanism to deliver the riveted tube in the second direction. The driving force of the first drive mechanism on the prior riveted tube is greater than the driving force of the second drive mechanism, and the prior riveted tube can still move in the first direction without being affected, thereby improving the riveting efficiency and reliability.

[0019] As an improvement, in step S2, the inspection mechanism detects that there is a previous riveted tube in the first conduit, and the inspection mechanism transmits a detection signal to the controller, and the controller controls the second drive mechanism to drive the subsequent riveted tube to move in the second direction. In this technical solution, in step S2, the previous riveted tube detaches from the second conduit and the subsequent riveted tube enters the second conduit, the inspection mechanism detects that there is a riveted tube in the first conduit, and the inspection mechanism transmits a detection signal to the controller, and the controller controls the second drive mechanism to transport the riveted tube in the second conduit along the second direction, the first drive mechanism drives the previous riveted tube to continue to move in the first direction, and the second drive mechanism drives the subsequent riveted tube to move in the second direction, so that the subsequent riveted tube is limited in the second conduit, thereby avoiding the splicing of the front and rear riveted tubes, and even if a new riveted tube is subsequently placed, it can avoid the new riveted tube from entering the first conduit, thereby improving the riveting efficiency and reliability.

[0020] As an improvement, the method further includes step S3: when the previous riveted tube detaches from the first conduit, the inspection mechanism detects that there is no riveted tube in the first conduit, and the inspection mechanism transmits a detection signal to the controller. The controller controls the second driving mechanism to drive the subsequent riveted tube to move in the first direction, and the subsequent riveted tube in the second conduit is transported into the first conduit, and the first driving mechanism drives the subsequent riveted tube to move in the first direction. In the present technical solution, in step S3, the previous riveted tube is conveyed into the pressure riveting mechanism and completely separated from the first conduit. At this time, the inspection mechanism detects that there is no riveted tube in the first conduit, and the inspection mechanism transmits a detection signal to the controller. The controller controls the second driving mechanism to drive the subsequent riveted tube to move along the first direction, so that the subsequent riveted tube can enter the first conduit along the first direction. At this time, the subsequent riveted tube exists in the first conduit and the second conduit at the same time. The first driving mechanism drives the subsequent riveted tube to move along the first direction. The inspection mechanism detects that there is a riveted tube in the first conduit, and the inspection mechanism transmits a detection signal to the controller. The controller controls the second driving mechanism to drive the subsequent riveted tube to move along the second direction. The driving force of the first driving mechanism is greater than or equal to the driving force of the second driving mechanism, that is, the force in the first direction on the subsequent riveted tube is greater than the force in the second direction, so that the subsequent riveted tube can be conveyed along the first direction. Subsequently, a new riveted tube is placed in the second conduit and the above three steps are repeated, thereby ensuring that the front and rear riveted tubes are always separated in the two conduits, improving the riveting efficiency and reliability, and improving the intelligence of the whole machine.

[0033] When only one riveted tube is placed in the second conduit 31, the second driving mechanism 32 cannot drive the riveted tube to move in the second direction by controlling the tube arrangement device 3 to stop or reverse operation, so that the riveted tube can enter the first conduit 21 in the first direction through the second conduit 31. After entering the first conduit 21, the riveted tube moves in the first direction through the first driving mechanism 22 to achieve transportation. When two riveted tubes are placed in the second conduit 31 front and back, the first riveted tube enters the first conduit 21 through the aforementioned steps, and when the rear riveted tube enters the second conduit 31, the tube arrangement device 3 operates normally to enable the second riveted tube to move in the first direction. The driving mechanism 32 drives the rear riveted tube to move in the second direction, so that the rear riveted tube cannot enter the first conduit 21 in the first direction. The rear riveted tube is limited in the second conduit 31, thereby separating the first riveted tube in the first conduit 21 and the rear riveted tube in the second conduit 31. The first and the rear in the present application are only used to indicate the order in which two adjacent riveted tubes enter the first conduit 21 and the second conduit 31.

No further details will be given later, so as to avoid the formation of spliced ​​riveted tubes after the two riveted tubes enter the first conduit 21 successively, thereby improving the riveting efficiency and reliability.

[0034] More specifically, the second driving mechanism 32 is electrically connected to the controller, and the second driving mechanism 32 can drive the riveting tube in the second conduit 31 to move along the first direction or the second direction through the controller. The second driving mechanism 32 is electrically connected to the controller, and the controller can control the second driving mechanism 32 to drive the riveting tube to move along the first direction or the second direction. When the first riveting tube is placed in the second conduit 31, the controller controls the second driving mechanism 32 to first convey the first riveting tube along the first direction, so that the first riveting tube can enter the first conduit 21 along the first direction. When the rear riveting tube is placed in the second conduit 31, the controller controls the second driving mechanism 32 to convey the rear riveting tube along the second direction, so that the rear riveting tube is limited in the second conduit 31, thereby being separated from the first riveting tube.

The second pipe delivery wheel 321 delivers or blocks the riveted tube in the second conduit 31 through bidirectional rotation. The second driving mechanism 32 is set to drive the second pipe delivery wheel 321 to rotate through the second motor 322, so that the second pipe delivery wheel 321 can drive the riveted tube in the second conduit 31 to move. The riveted tube is placed in the second conduit 31. The output shaft of the second motor 322 is connected to the second pipe delivery wheel 321 to drive the second pipe delivery wheel 321 to rotate forward or reversely. The second pipe delivery wheel 321 can drive the riveted tube in the second conduit 31 to enter the first conduit 21 or block the riveted tube in the second conduit 31 from entering the first conduit 21 through bidirectional rotation, thereby improving the riveting efficiency and reliability. In this solution, the controller adopts a conventional PLC controller or a single-chip microcomputer, and controls the second motor 322 to rotate forward or reversely and stop through the controller. Figure 4 and Figure 5 The straight arrows in the figure represent the movement direction of the riveted tube, and the arc arrows represent the operation directions of the first driving mechanism 22 and the second driving mechanism 32.

[0036] More specifically, Figure 3As shown, the tube delivery device 2 is connected with a tube inspection mechanism 4, which is electrically connected to the controller. The tube inspection mechanism 4 is used to detect whether there is a riveted tube in the first conduit 21 and transmit the detection signal to the controller. The controller controls the second tube delivery wheel 321 to rotate bidirectionally through the detection signal. The tube delivery device 2 is connected to the tube inspection mechanism 4, and the tube inspection mechanism 4 is used to detect whether there is a riveted tube in the first conduit 21. The tube inspection mechanism 4 is electrically connected to the controller. The tube inspection mechanism 4 can transmit the detection signal of whether there is a riveted tube in the first conduit 21 to the controller, and the controller controls the second tube delivery wheel 321 to rotate bidirectionally according to the detection signal.

[0037] When the tube inspection component detects that there is no riveted tube in the first conduit 21, the tube inspection component transmits the detection signal to the controller, such as Figure 5 As shown, the controller controls the second tube delivery wheel 321 to rotate so as to deliver the riveted tube in the second conduit 31 along the first direction, so that the riveted tube in the second conduit 31 enters the first conduit 21;

[0038] When the tube inspection component detects that there is a riveted tube in the first conduit 21, the tube inspection component transmits the detection signal to the controller, such as Figure 4 As shown, the controller controls the second tube delivery wheel 321 to rotate in the opposite direction so as to deliver the riveted tubes in the second conduit 31 along the second direction, so that the riveted tubes in the second conduit 31 cannot enter the first conduit 21, thereby separating the riveted tubes in the first conduit 21 from the riveted tubes in the second conduit 31;

[0039] When the riveted tube in the first conduit 21 is completely separated from the first conduit 21, the tube detection component detects that there is no riveted tube in the first conduit 21 and transmits the detection signal to the controller. Figure 5 As shown, the controller controls the second tube delivery wheel 321 to rotate so that the riveted tube in the second conduit 31 can be delivered to the first conduit 21 along the first direction, and the above steps are repeated, thereby avoiding the splicing of the front and rear riveted tubes, improving the riveting efficiency and reliability, and improving the intelligence level of the whole machine.

[0040] More specifically, Figure 4 As shown, the first direction is the direction of gravity, and the second direction is opposite to the direction of gravity, that is, the pipe arrangement device 3 and the pipe delivery device 2 are distributed up and down, so that the riveted pipe in the first conduit 21 is not only affected by the conveying action of the first driving mechanism 22 but also by its own gravity, thereby improving the pipe delivery efficiency of the pipe delivery device 2. On the other hand, the riveted pipe in the second conduit 31 can also enter the first conduit 21 under the action of its own gravity, and when it is necessary to separate the front and rear riveted pipes, the riveted pipe in the second conduit 31 stops falling due to the offset of gravity and the conveying force of the second driving mechanism 32 along the second direction, and is thus limited in the second conduit 31, thereby avoiding the splicing of the front and rear riveted pipes, improving the riveting efficiency and reliability, and improving the intelligence of the whole machine. The upper and lower installation distribution method is simple and saves installation space.

[0041] More specifically, the driving force of the first driving mechanism 22 is greater than or equal to the driving force of the second driving mechanism 32. When a single riveted tube enters the second conduit 31, the inspection mechanism 4 first detects that there is no riveted tube in the first conduit 21, and the controller controls the second tube-feeding wheel 321 to rotate to convey the riveted tube to the first conduit 21 along the first direction. At this time, the inspection mechanism 4 detects that there is a riveted tube in the first conduit 21, and the controller controls the second tube-feeding wheel 321 to rotate in the opposite direction to convey the riveted tube along the second direction. The riveted tube exists in the first conduit 21 and the second conduit 31 at the same time. By setting the driving force of the first driving mechanism 22 to be greater than or equal to the driving force of the second driving mechanism 32, that is, the force in the first direction on the riveted tube is greater than the force in the second direction, the riveted tube can be conveyed along the first direction. During this process, the second tube-feeding wheel 321 keeps conveying the riveted tube in the second direction. Even if a new riveted tube is subsequently placed, the new riveted tube can be prevented from entering the first conduit 21, thereby avoiding the splicing of the front and rear riveted tubes, improving the riveting efficiency and reliability, and improving the intelligence and reliability of the whole machine.

[0042] More specifically, Figures 1 to 3 As shown, the first driving mechanism 22 is provided with a first pipe delivery wheel 221 and a first motor 222. The first motor 222 drives the first pipe delivery wheel 221 to rotate so that the riveted tube in the first conduit 21 moves along the first direction. The first driving mechanism 22 is provided to drive the first pipe delivery wheel 221 to rotate through the first motor 222, so that the first pipe delivery wheel 221 can drive the riveted tube in the first conduit 21 to move, and the riveted tube enters the first conduit 21. The output shaft of the first motor 222 is connected to the first pipe delivery wheel 221 to drive the first pipe delivery wheel 221 to rotate. The first pipe delivery wheel 221 can drive the riveted tube in the first conduit 21 to move along the first direction by rotating, thereby completing the transportation, achieving the purpose of pipe delivery, and improving the efficiency of pipe delivery.

[0043] More specifically, Figures 1 to 3 As shown, the pipe delivery device 2 is provided with a first roller 23 opposite to the first pipe delivery wheel 221, and the first roller 23 cooperates with the first pipe delivery wheel 221 to make the riveted pipe in the first conduit 21 move along the first direction. By adding the first roller 23 in the pipe delivery device 2, the first roller 23 and the first pipe delivery wheel 221 are relatively distributed, one side of the riveted pipe in the first conduit 21 abuts against the first roller 23, and the other side abuts against the first pipe delivery wheel 221, so that the first roller 23 can rotate synchronously when the first pipe delivery wheel 221 rotates to deliver the riveted pipe. The first roller 23 cooperates with the first pipe delivery wheel 221 to deliver the riveted pipe, so as to avoid the riveted pipe abutting against the inner wall of the first conduit 21 to increase the friction force, thereby improving the pipe delivery efficiency.

[0044] Embodiment 2

[0045] like Figures 1 to 5As shown, this embodiment provides a control method for a binding machine, including a frame 1, on which a pipe feeding device 2 and a pipe discharging device 3 are installed, the pipe feeding device 2 includes a first guide tube 21 and a first driving mechanism 22, the pipe discharging device 3 includes a second guide tube 31 and a second driving mechanism 32, the riveting tube is transported to the riveting mechanism by the pipe feeding device 2, the riveting tube is placed in the first guide tube 21, and the first driving mechanism 22 drives the riveting tube to move along a first direction to achieve transportation, by installing the pipe discharging device 3 on the second direction of the pipe feeding device 2, the riveting tube is placed in the second guide tube 31, and the second driving mechanism 32 drives the riveting tube to move along a second direction to be limited in the second guide tube 31, the first direction is opposite to the second direction, so as to prevent the riveting tube in the second guide tube 31 from entering the first guide tube 21 along the first direction, and avoid the front and rear riveting tubes from sequentially entering the first guide tube 21 to form a spliced ​​riveting tube, thereby improving the riveting efficiency and reliability;

[0046] The following steps are also included:

[0047] S1. When the first riveted tube passes through the second conduit 31 and enters the first conduit 21, the first driving mechanism 22 drives the first riveted tube to move in the first direction. Figure 4 As shown, the second driving mechanism 32 drives the first riveted tube to move along the second direction, and the driving force of the first driving mechanism 22 is greater than the driving force of the second driving mechanism 32 to make the first riveted tube move along the first direction;

[0048] S2, when the first riveted tube is separated from the second guide tube 31 and the second riveted tube enters the second guide tube 31, the first driving mechanism 22 drives the first riveted tube to continue to move along the first direction, such as Figure 4 As shown, the second driving mechanism 32 drives the rear riveted tube to move in the second direction to reversely transport the rear riveted tube, so that the rear riveted tube is confined in the second guide tube 31 and is separated from the preceding riveted tube;

[0049] When the first riveted tube passes through the second conduit 31 and enters the first conduit 21, the first riveted tube is simultaneously present in the first conduit 21 and the second conduit 31, and the first driving mechanism 22 drives the first riveted tube to move along the first direction, such as Figure 4 As shown, the second driving mechanism 32 drives the preceding riveted tube to move in the second direction, and the driving force of the first driving mechanism 22 is greater than or equal to the driving force of the second driving mechanism 32, that is, the force applied to the preceding riveted tube in the first direction is greater than the force applied to the preceding riveted tube in the second direction, so that the preceding riveted tube can be transported in the first direction;

[0050] When the first riveted tube is separated from the second guide tube 31 and the second riveted tube enters the second guide tube 31, the first riveted tube is located in the first guide tube 21, and the first driving mechanism 22 drives the first riveted tube to continue to move in the first direction. Figure 4As shown, the second driving mechanism 32 drives the rear riveted tube to move in the second direction to reversely transport the rear riveted tube, so that the rear riveted tube is confined in the second conduit 31, and the front riveted tube in the first conduit 21 and the rear riveted tube in the second conduit 31 are separated, so as to avoid the front and rear riveted tubes from forming a spliced ​​riveted tube after entering the first conduit 21 in sequence, thereby improving the riveting efficiency and reliability.

[0051] More specifically, Figures 1 to 5 As shown, the tube delivery device 2 is connected to a tube inspection mechanism 4, and the second driving mechanism 32 and the tube inspection mechanism 4 are both electrically connected to the controller. The tube inspection mechanism 4 detects whether there is a riveted tube in the first conduit 21. The second driving mechanism 32 and the tube inspection mechanism 4 are both electrically connected to the controller. The tube inspection mechanism 4 can transmit a detection signal of whether there is a riveted tube in the first conduit 21 to the controller, and the controller controls the second tube delivery wheel 321 to rotate bidirectionally according to the detection signal. In step S1, the first riveted tube passes through the second conduit 31 and enters the first conduit 21. The tube inspection mechanism 4 detects that there is a riveted tube in the first conduit 21, and the tube inspection mechanism 4 transmits the detection signal to the controller. Figure 4 As shown, the controller controls the second driving mechanism 32 to transport the riveted tube along the second direction. The driving force of the first driving mechanism 22 on the riveted tube is greater than the driving force of the second driving mechanism 32. The riveted tube can still move in the first direction without being affected, thereby improving the riveting efficiency and reliability.

[0052] More specifically, when the first riveted tube is separated from the second conduit 31 and the second riveted tube enters the second conduit 31, the inspection mechanism 4 detects that there is a riveted tube in the first conduit 21, and the inspection mechanism 4 transmits a detection signal to the controller, such as Figure 4 As shown, the controller controls the second driving mechanism 32 to transport the riveted tube in the second conduit 31 along the second direction, the first driving mechanism 22 drives the preceding riveted tube to continue to move along the first direction, and the second driving mechanism 32 drives the following riveted tube to move along the second direction, so that the following riveted tube is limited in the second conduit 31, thereby avoiding the front and rear riveted tubes from being spliced, and even if a new riveted tube is subsequently placed, it can be avoided that the new riveted tube enters the first conduit 21, thereby improving the riveting efficiency and reliability.

[0053] More specifically, the method further includes step S3: when the previously riveted tube is separated from the first conduit 21, the inspection mechanism 4 detects that there is no riveted tube in the first conduit 21, and the inspection mechanism 4 transmits a detection signal to the controller, such as Figure 5 As shown, the controller controls the second driving mechanism 32 to drive the rear riveted tube to move along the first direction, the rear riveted tube in the second conduit 31 is transported into the first conduit 21, and the first driving mechanism 22 drives the rear riveted tube to move along the first direction;

[0054] In step S3, the first riveted tube is transported into the pressure riveting mechanism and completely separated from the first conduit 21. At this time, the inspection mechanism 4 detects that there is no riveted tube in the first conduit 21, and the inspection mechanism 4 transmits a detection signal to the controller. Figure 5 As shown, the controller controls the second driving mechanism 32 to drive the rear riveted tube to move in the first direction, so that the rear riveted tube can enter the first conduit 21 along the first direction. At this time, the rear riveted tube is simultaneously present in the first conduit 21 and the second conduit 31. The first driving mechanism 22 drives the rear riveted tube to move in the first direction. The inspection mechanism 4 detects that there is a riveted tube in the first conduit 21, and the inspection mechanism 4 transmits a detection signal to the controller, such as Figure 4 As shown, the controller controls the second driving mechanism 32 to drive the rear riveted tube to move in the second direction, and the driving force of the first driving mechanism 22 is greater than or equal to the driving force of the second driving mechanism 32, that is, the force applied to the rear riveted tube in the first direction is greater than the force applied to the rear riveted tube in the second direction, so that the rear riveted tube can be transported in the first direction. Subsequently, a new riveted tube is placed in the second conduit 31 and the aforementioned three steps are repeated, so as to ensure that the front and rear riveted tubes are always separated in the two conduits, thereby improving the riveting efficiency and reliability, and improving the intelligence level of the whole machine.

[0055] The present application is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present application. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present application.
