It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
In the present specification, the "front" and the "rear" are directions determined based on the conveying direction of the conveying structure 20.
Referring to fig. 1 and 2, a safe feed mechanism of automatic bag sealer, include frame 10 and establish the transport structure 20 on frame 10, frame 10 is equipped with limiting plate 40 in a side of transport structure 20 front end, and frame 10 is equipped with connecting plate 50 in transport structure 20 top, be fixed with detector 60 and telescopic cylinder 70 on the connecting plate 50, telescopic cylinder 70 establishes the place ahead at the transmission device, and detector 60 can be infrared ray detector 60 or travel switch, and detector 60 establishes the place ahead at telescopic cylinder 70, still be connected with the gas outlet on the connecting plate 50 and blow to the clean trachea 80 of transport structure 20, clean trachea 80 keeps away from connecting plate 50 one end and is connected with air feeder 90, has concatenated control valve 100 on the clean trachea 80.
In the existing automatic edge bonding machine, a base 10 is provided with a conveying structure 20 and rollers 30, and the rollers 30 are arranged above the conveying structure 20, so that when a plate is arranged on the rollers 30 and the conveying structure 20, the plate is pressed on the conveying structure 20 by the rollers 30, and then under the drive of the conveying structure 20, the plate sequentially passes through stations of multiple processes of gluing, edge bonding, cutting, head aligning, fine trimming, edge scraping, polishing and the like, and edge bonding of the plate is realized.
In the present application, by fixing the connecting plate 50 on the machine base 10, the connecting plate 50 is disposed in front of the roller 30 and the conveying structure 20, and the connecting plate 50 fixes the telescopic cylinder 70 which can extend downwards from the telescopic rod. When the telescopic rod of the telescopic cylinder 70 is in a contracted state, the distance between the tail end of the telescopic rod of the telescopic cylinder 70 and the plane on the machine base 10 for placing the plate is slightly larger than or equal to the distance between the roller 30 and the conveying structure 20, so that the thickness of the plate entering between the roller 30 and the conveying structure 20 is equal to or smaller than the distance between the roller 30 and the conveying structure 20, namely, the plate cannot be clamped between the roller 30 and the conveying structure 20 in a normal working state. When the telescopic rod of the telescopic cylinder 70 is in a downward extending state, the distance between the tail end of the telescopic rod of the telescopic cylinder 70 and the plane of the machine base 10 for placing the plates is smaller than the thickness of the plates, so that when the telescopic rod of the telescopic cylinder 70 is in a downward extending state, the plates can be prevented from passing through.
Wherein, set up detector 60 in the place ahead of telescopic cylinder 70, when detector 60 detected panel, automatic bag sealer's control system was with this signal and the last panel signal when through, judged whether have enough big spacing distance between two panels, if, telescopic cylinder 70 keeps in the shrink state, if not, then the telescopic link of telescopic cylinder 70 is in the state that stretches out downwards, treat whether have enough big spacing distance between two panels after, control telescopic cylinder 70's piston rod shrink.
In the above, under normal operation, the running speed of the conveying structure 20 is in a constant speed state or a motion state in which the speed is regularly changed, so that the interval between two sheets can be determined by the conveying time, or by obtaining the rotation angle of the driving motor of the conveying structure 20, that is, the conveying distance of the conveying structure 20 can be calculated by the rotation angle of the driving motor.
Specifically, the connecting plate 50 is connected with a cleaning air pipe 80, the cleaning air pipe 80 is arranged on the side face of the telescopic cylinder 70, air blown out from the cleaning air pipe 80 is used for blowing away sundries on the surface of the plate, and the phenomenon that the automatic edge sealing machine is blocked due to the fact that the sundries on the plate enter between the roller 30 and the conveying structure 20 along with the plate is avoided.
In the above, by arranging the detector 60, the telescopic cylinder 70 and the cleaning air pipe 80 in front of the conveying structure 20 of the automatic edge bonding machine, the telescopic cylinder 70 can limit the thickness of the plate material entering the conveying structure 20, and also can prevent the plate material from entering the position of the conveying structure 20, so that when a plate material exceeding the distance value between the roller 30 and the conveying structure 20 is put on the automatic edge bonding machine, the plate material is blocked by the piston rod of the telescopic cylinder 70, and therefore the plate material cannot reach the conveying structure 20, that is, the plate material cannot be conveyed by the conveying structure 20, and therefore, the plate material is prevented from being stuck between the roller 30 and the conveying structure 20 due to the overlarge thickness of the plate material; and can control the telescopic link of telescopic cylinder 70 to stretch out and draw back through the panel signal that detector 60 detected, and then reach and guarantee to have sufficient distance between two adjacent panels, avoid between two adjacent panels undersize and influence going on of processes such as subsequent alignment.
In the above, after the plates pass through the position of the telescopic cylinder 70, the control system may also control the telescopic rod of the telescopic cylinder 70 to extend, and when the detector 60 to be detected detects the next plate and the distance between two adjacent plates meets the set value, the control system controls the telescopic rod of the telescopic cylinder 70 to contract again.
In the above, the clean air pipe 80 can continuously eject air when the automatic edge bonding machine is in a starting state, and the on-off of the air can also be controlled by the control valve 100, that is, the control valve 100 is opened when a plate passes through, so that the clean air pipe 80 blows air only when the plate passes through, and the energy consumption of the air supply device 90 for supplying clean air is reduced.
In a preferred embodiment, the telescopic cylinder 70 is a double-head double-outlet cylinder, that is, the telescopic rod penetrates through the whole cylinder body of the telescopic cylinder 70, the telescopic rod of the telescopic cylinder 70 is provided with a central through hole, and the cleaning air tube 80 is a hose and is connected to one end of the telescopic rod far away from the conveying structure 20, so that the cleaning air tube 80 is communicated with the central through hole. In this embodiment, the distance between the end of the telescopic rod of the telescopic cylinder 70 and the plane on the base 10 for placing the plate is slightly greater than the distance between the roller 30 and the conveying structure 20, so that a gap for ejecting gas exists between the end of the telescopic rod of the telescopic cylinder 70 and the surface of the plate, thereby realizing dust removal and other objects on the surface of the plate, and reducing the installation space.
In a preferred embodiment, since the plate collides with the telescopic rod of the telescopic cylinder 70, the telescopic rod is sleeved with the rubber sleeve 120 at the end far away from the clean air tube 80, and the rubber sleeve 120 is fixed on the telescopic rod, so that when the plate contacts with the telescopic rod of the telescopic cylinder 70, the rubber sleeve 120 has a buffering effect on the plate; the size of the air gap between the end of the telescopic rod of the telescopic cylinder 70 and the surface of the plate can be adjusted by adjusting the position of the rubber sleeve 120 relative to the telescopic rod, so that the plate is blown by large air pressure.
Specifically, the connecting plate 50 is L-shaped, one end of the connecting plate 50 is fixed on the machine base 10, the other end is suspended, and the detector 60 and the telescopic cylinder 70 are fixed at the suspended end of the connecting plate 50; the suspended end of the connecting plate 50 is provided with a plurality of mounting holes, and the detector 60 and the telescopic cylinder 70 are fixed on the mounting holes.

A. the controller 110 controls the telescopic rod of the telescopic cylinder 70 to be in an extending state;
B. the detector 60 detects the plate and sends a signal to the controller 110, and the controller 110 controls the telescopic rod of the telescopic cylinder 70 to contract according to the signal of the detector 60 and simultaneously opens the control valve 100;
C. the detector 60 no longer detects the plate and sends a signal to the controller 110, and the controller 110 controls the extension rod of the extension cylinder 70 to extend according to the signal of the detector 60 and closes the control valve 100; D. the above steps are repeated until the controller 110 receives a shutdown signal.
In the above, after the automatic edge bonding machine is started, the telescopic rod of the telescopic cylinder 70 is in an extended state, after the device 60 to be detected detects a plate, the telescopic rod of the telescopic cylinder 70 is controlled to contract, the control valve 100 is opened to blow the plate, when the plate completely passes through the position of the telescopic cylinder 70, the controller 110 controls the telescopic rod of the telescopic cylinder 70 to extend, and the blowing is stopped, and when each plate passes through, the action is executed, that is, the steps a, B and C are repeated. In the method, the air blowing is stopped in the gap time when the two plates pass through the telescopic air cylinder 70, so that the waste of air is reduced, namely, the energy consumption of the air supply equipment 90 for providing clean air is reduced, and the telescopic rod of the telescopic air cylinder 70 is in the extending state, so that other objects are prevented from entering the position between the roller 30 and the conveying structure 20, and the safety of the automatic edge bonding machine during working is improved.
In a preferred embodiment, when the detector 60 no longer detects the sheet material, the conveying distance L1 is recorded, when step B is executed, the detector 60 detects the sheet material and sends a signal to the controller 110, and the controller 110 determines whether the conveying distance L1 passed by the conveying structure 20 is greater than or equal to the set conveying distance L2 when step C to step B are executed, and if yes, controls the telescopic rod of the telescopic cylinder 70 to contract and simultaneously opens the control valve 100; if not, after the conveying distance L1 passed by the conveying structure 20 is greater than or equal to the set conveying distance L2, the telescopic rod of the telescopic cylinder 70 is controlled to contract, and the control valve 100 is opened.
In the above embodiment, when the distance between the plate to be fed into the automatic edge bonding machine and the previous plate is calculated and the distance value between the two paperboards is greater than or equal to the set transfer distance L2, the telescopic rod of the telescopic cylinder 70 is controlled to contract, so that a certain distance is formed between the two adjacent plates, and the situation that the two adjacent plates are too close to each other to affect the subsequent processes of cutting, aligning and the like is avoided.
In a preferred embodiment, when the clean air pipe 80 communicates with the central through hole of the telescopic cylinder 70, the conveying structure 20 includes a driving motor with an angle detector, before step a, that is, after the automatic edge bonding machine is turned on, a conveying distance L2 is set on the controller 110, or an angle θ 2 required to rotate the driving motor is set on the controller 110 corresponding to the conveying distance L2, and after the detector 60 detects a plate, when the real-time conveying distance of the structure 20 to be conveyed reaches the set conveying distance L2, or the real-time rotation angle of the driving motor is equal to the set angle θ 2, the controller 110 controls the control valve 100 to open, so that air blowing is started only when the plate passes through the position of the telescopic cylinder 70, thereby reducing waste of air, that is, and reducing energy consumption of the air supply device 90.
In a preferred embodiment, the controller 110 controls the control valve 100 to close when the rotation angle of the driving motor is not changed. In this embodiment, when the automatic edge bonding machine is in the operating state, but the conveying structure 20 is in the jammed state, the plate is not actually conveyed, and the condition can be accurately determined by the change of the rotation angle of the driving motor, so as to control the control valve 100 to close, thereby reducing the waste of gas, i.e., reducing the energy consumption of the gas supply device 90. In this state, the controller 110 may also control other mechanisms to stop working at the same time, so as to avoid damage.
