[0001] The present application relates to the technical field of binding equipment, more particularly to a full-automatic binding machine and a control method thereof. BACKGROUND

[0002] The full-automatic binding machine is a kind of equipment for binding books, magazines and other printed matter. Its technical background can be traced back to the traditional hand binding process, and the modern full-automatic binding machine is developed on the basis of the traditional process combined with the development of automation technology.

[0003] The full-automatic binding machine includes a punching device, a pipe cutting device, a hot riveting device, etc. For the convenience of use, some binding machines are also provided with a pipe receiving support mechanism, which is used to receive the cut riveting pipe, and waits for the guide needle assembly on the punch seat to transport the cut riveting pipe to the workbench for riveting. However, the existing binding machine has the following defects: there is no device on the current binding machine for detecting whether there is a riveting pipe on the guide needle of the guide needle assembly. During the working process of the binding machine, if there is a residual pipe on the guide needle, the residual pipe will be pushed to the pipe receiving support mechanism during the rising process of the guide needle to receive the riveting pipe, which may damage the pipe receiving support mechanism and affect the binding effect, and in severe cases, it may cause damage to the binding machine or scrap the bound paper. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a full-automatic binding machine which can detect whether there is a residual pipe on the guide needle, effectively avoid damaging the pipe receiving support mechanism, and avoid damaging the binding machine or scrapping the bound paper.

[0006] After adopting the above structure, the full-automatic binding machine of the present application has the following advantages compared with the prior art:

[0007] Since the full-automatic binding machine of the present application further comprises a residual pipe detector for detecting the position of the pipe receiving support, during the pipe receiving process, the position of the pipe receiving support detected by the residual pipe detector can determine whether there is a residual pipe on the guide needle, and can prompt the user to clean the residual pipe on the guide needle, which can effectively avoid damaging the pipe receiving support mechanism, and avoid damaging the binding machine or scrapping the bound paper.

[0008] As improvement, the residual pipe detector is a photoelectric sensor; the photoelectric sensor comprises a photoelectric seat and photoelectric detection elements; the photoelectric seat is installed on the frame, and the photoelectric detection elements are installed on the photoelectric seat; a channel is left between the photoelectric detection elements for the top of the pipe support to extend into; when the top of the pipe support extends into the channel, the photoelectric detection elements generate signals; and the photoelectric detection elements are electrically connected with the control unit.

With this structure, the residual pipe is clamped by the blade structure, and the residual pipe is not easy to fall off.

[0012] Another technical problem to be solved by the present application is to provide a control method of a full-automatic binding machine, through which it can be detected whether there is a residual pipe on the guide needle, and the pipe support mechanism can be effectively prevented from being damaged, and the binding machine or the bound paper can be effectively prevented from being damaged or scrapped.

The puncher seat is installed on the lower side of the workbench of the frame 1, and the puncher seat is provided with a puncher assembly 4 and a guide needle assembly. The puncher seat can rotate within a range of 90°, and in the process of back-and-forth rotation, the puncher assembly 4 and the guide needle assembly can be alternately sent to the riveting position of the workbench of the frame 1. The above structure is the prior art of the full-automatic stapler, which will not be described here.

[0028] The full-automatic bookbinding machine further comprises a residual pipe detector, which is installed on the frame 1 and located on the upper side of the top of the pipe receiving support 301 of the pipe receiving support 301 assembly 3, and is electrically connected with the control unit; the residual pipe detector is used to detect the position of the pipe receiving support 301.

[0029] The residual pipe detector is a photoelectric sensor, which comprises a photoelectric seat 6 and photoelectric detection elements 7; the photoelectric seat 6 is installed on the frame 1, and the photoelectric detection elements 7 are installed on the photoelectric seat 6; a channel 8 is left between the photoelectric detection elements 7 for the top of the pipe receiving support 301 to extend into; when the top of the pipe receiving support 301 extends into the channel 8, the photoelectric detection elements 7 will generate a signal; the photoelectric detection elements 7 are electrically connected with the control unit.

[0030] The pipe receiving support 301 is provided with a U-shaped groove 302 for the guide needle 5 of the guide needle assembly to embed, and one side wall or opposite two side walls of the U-shaped groove 302 are provided with protrusions for clamping the residual pipe. Two sides of the protrusions are respectively provided with cut surfaces 303, and the connection between the two cut surfaces 303 forms a blade structure 304, which is used to clamp the residual pipe.

[0031] The residual pipe detector can also be a micro switch, which is installed on the frame 1 and electrically connected with the control unit; the micro switch is installed above the top of the pipe receiving support 301, and can be contacted by the pipe receiving support 301 after the pipe receiving support 301 is lifted by a certain distance, and the micro switch will generate a signal and transmit the signal to the control unit. Embodiment

[0032] The embodiment discloses a control method of a full-automatic bookbinding machine, which comprises the following steps:

[0033] S1, the full-automatic bookbinding machine performs a pipe receiving action; in the embodiment, the pipe receiving action can be performed when the "punching", "binding" or "annular cutter" button on the display panel of the full-automatic bookbinding machine is pressed. The control unit controls the pipe receiving support to move downward, and the top of the pipe receiving support is separated from the residual pipe detector, which is a photoelectric sensor or a micro switch.

[0034] S2, the control unit controls the puncher base to be transposed by 90°, and the puncher base is connected with a guide needle assembly. After the transposition is completed, the guide needle of the guide needle assembly is just placed in the U-shaped groove of the pipe receiving support. The diameter of the U-shaped groove of the pipe receiving support is greater than the diameter of the top needle and less than the diameter of the rivet pipe.

[0035] S3, the control unit controls the punching motor to drive the punching base to rise, at this time the control unit monitors the Hall step number of the punching motor. If the punching base rises for a set time and the pipe receiving support does not trigger the residual pipe detector to work, the control unit determines that there is no residual rivet pipe on the guide needle, and enters step S5; if the punching base rises and triggers the residual pipe detector to work within the set time, the control unit determines that there is residual rivet pipe on the guide needle, and enters step S4. The set time is counted by the Hall step number of the punching motor. In the specific embodiment, the set time is when the Hall step number is 8-10, and the set time is when the Hall step number is 9, which is the best.

[0036] When there is residual pipe on the guide needle, and the length of the residual pipe is less than 14MM, after the punching base is transposed by 90°, the guide needle is placed in the U-shaped groove of the pipe receiving support, and the residual pipe on the ejector pin is just below the pipe receiving support. Since the diameter of the U-shaped groove of the pipe receiving support is smaller than the diameter of the rivet pipe, when the guide needle rises, the rivet pipe will push the pipe receiving support to rise. When there is residual pipe on the guide needle, and the length of the residual pipe is greater than 14MM and less than 70MM, after the punching base is transposed by 90°, the residual pipe is clamped into the U-shaped groove at the bottom of the pipe receiving support, and the blade-shaped structure is clamped on the outer wall of the residual pipe. At this time, when the guide needle rises, the rivet pipe will drive the pipe receiving support to rise.

[0037] S4, if there is residual rivet pipe on the guide needle, the control unit controls the output unit to prompt the user to clean the residual pipe on the guide needle. The output unit is a display unit or a voice broadcast unit.

[0038] S5, start the ejector pin rising function to move the ejector pin to an operable position, then eliminate the residual pipe fault, start the reset program, and then the punching and riveting program can be restarted.

[0039] The present application is not limited to the above-mentioned best embodiment, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solution with the same or similar technical solutions as the present application falls within the protection scope of the present application.
