Detailed implementation manners

[0044] The following further describes the present utility model with specific embodiments in conjunction with the accompanying drawings. Refer to Figures 1 - 11 :

[0045] A tape storage mechanism of a belt tying machine includes

[0046] The tape reel assembly 101 is used to install the tape reel 1011; a locking device 1012 is provided on the tape reel assembly 101; the locking device 1012 enables the tape reel to have a locked state and a rotatable state; when the tape reel is in the locked state, it cannot rotate; when the tape reel is in the rotatable state, it can be pulled by the tape and rotate to supply the tape into the tape storage mechanism; in this solution, the tape reel is rotatable when the locking device 1012 is in the energized state, and the tape reel is locked when the locking device 1012 is in the de-energized state.

[0047] A plurality of fixed rollers 102 are installed on one side of the tape storage mechanism; the fixed rollers are used for the tape to bend around.

[0048] A plurality of movable rollers 1031 are installed on the other side of the tape storage mechanism; the movable rollers 1031 are used for the tape to bend around; the fixed rollers 102 and the movable rollers 1031 cooperate to form a tape storage area 3.

[0049] The moving assembly 103 is movably installed on the frame; the movable rollers 1031 are installed on the moving assembly; the moving assembly 103 can move between a first position and a second position; when the moving assembly 103 moves to the first position, the movable rollers 1031 move away from the fixed rollers 102 and store the tape; when the moving assembly 103 moves to the second position, the movable rollers 1031 approach the fixed rollers 102 and feed the tape.

[0050] The detection roller 104 is used for the tape to bend around; the detection roller is installed on the detection bracket.

[0051] The detection bracket 105 is rotatably or movably installed on the frame; the detection bracket is configured with a damping member 107, and the damping member gives a certain resistance to the detection bracket.

[0052] The triggering device 106 is used to obtain the movement of the detection bracket; when the detection bracket moves, the triggering device indirectly or directly controls the locking device 1012 to stop working.

[0053] It should be noted that the moving assembly 103 and the movable rollers 1031 operate synchronously. Therefore, in the initial stage of the moving assembly 103 resetting to the first position, the tape storage process of the strapping machine obtains the tape from the loop knot mechanism, and this tape storage process is equal to the tape withdrawal process; after the tape withdrawal is completed, the moving assembly 103 continues to reset to the first position, and the tape is in a taut state during this process; when the tape drives the detection roller 104, the locking device 1012 enables the tape reel to be rotatable, and the tape storage process of the strapping machine obtains the tape from the tape reel.

[0054] Preferably, the damping component 107 is an electromagnetic damper with adjustable resistance, and a gear 1071 is installed on the output shaft of the electromagnetic damper; when the items or tapes to be packed change, it is necessary to adjust the tension of the tape during the tape retraction process to achieve a better packing effect; in this application, only by setting the working current or working voltage of the electromagnetic damper in the program can the resistance be adjusted and the tension of the tape during the tape retraction process be changed. Correspondingly, if the damping component 107 is a spring, its ability to adjust the resistance is relatively lacking.

[0055] The detection bracket 105 is a swing arm, the middle part of the swing arm is rotatably installed on the frame body, the detection roller 104 is installed at the lower end of the swing arm, and a tooth surface part 1054 is arranged at the upper end of the swing arm; the tooth surface part 1054 meshes with the gear 1071; the rotation point 1052 in the middle of the swing arm is located in the upper part of the swing arm, and the swing arm forms a simple lever structure, which enables the force at the lower part of the swing arm to be appropriately amplified and transmitted to the upper tooth surface part, making the detection more sensitive; the arc-shaped tooth surface part 1054 and the gear 1071 are matched to achieve the stability of the damping component 107, and there will be no situation where the resistance changes suddenly; an induction part 1051 is arranged on one side of the swing arm; the triggering device 106 is a sensor arranged on the frame body, and the sensor detects the movement of the induction part 1051. A part of the structure of the induction part 1051 extends between the two sensors. When the induction part 1051 exits between the two sensors, the photoelectric signal between the two sensors is turned on; the controller of the tape tying machine receives the corresponding photoelectric signal and controls the locking device 1012, and the locking device enables the tape reel to rotate; a abutting part 1053 is arranged on the swing arm, and a gear position part 1055 is arranged on the frame body; when the movement angle of the swing arm reaches a certain degree, the abutting part 1053 presses tightly on the gear position part 1055, so that the swing arm cannot continue to swing, achieving the effect of safety limit.

[0056] Preferably, the plurality of fixed rollers 102 and the plurality of moving rollers 1031 are arranged vertically; the fixed rollers 102 and the moving rollers 1031 are staggered with each other in the horizontal direction; the detection roller 104 is arranged in the same column as the fixed rollers 102. In the solution of this application, the fixed rollers 102 and the moving rollers 1031 are arranged left and right. The detection roller is arranged in the middle of the queue of the fixed rollers. As Figure 1 shown, after the tape comes out of the tape reel, it winds the tape from right to left in sequence, first winds a roller on the right side, then winds a roller on the left side, and then passes through the tape feeding roller group 201 from top to bottom.

[0057] Preferably, a slide rail 302, a synchronous belt assembly 301, and a driving motor 303 are installed on the frame body 1; the conveying direction of the synchronous belt assembly 301 is parallel to that of the slide rail 302;

[0058] The moving assembly 103 is installed on the slide rail 302, and the slide rail guides the moving assembly to move between a first position and a second position; as Figure 1 shown, the position where the moving assembly is located is the first position, which is also the limit position for the moving assembly to move leftward during actual operation; the limit position for the moving assembly to move rightward during actual operation is the second position;

[0059] One side of the moving assembly 103 is fixedly connected to the synchronous belt assembly 301; the driving motor 303 drives the moving assembly through the synchronous belt assembly 301, and the movement of the moving assembly is controlled by the driving motor to realize the switching of the moving assembly between the first position and the second position.

[0060] This application also provides a variant structure: the moving assembly 103 is divided from an integral component into two independent components; the moving assembly 103 includes a first moving bracket 1033 and a second moving bracket 1034; the first moving bracket 1033 and the second moving bracket 1034 are of a split structure; both the first moving bracket 1033 and the second moving bracket 1034 are installed on the slide rail 302;

[0061] The moving roller 1031 is installed on the front side of the first moving bracket 1033, and the rope 1035 is installed on the rear side of the first moving bracket 1033. The other end of the rope passes through the steering roller 1037 and suspends a counterweight 1036;

[0062] The second moving bracket 1034 is provided with a connecting portion 1039, and is fixedly connected to the synchronous belt assembly 301 through the connecting portion 1039; the driving motor drives the synchronous belt assembly and the second moving bracket 1034;

[0063] The second moving bracket 1034 is located between the first moving bracket 1033 and the fixed roller 102. After the belt storage is completed, the drive motor moves the second moving bracket 1034 to the second position, and the first moving bracket 1033 remains in the first position under the action of the counterweight; during the belt feeding stage, the belt feeding roller group 201 clamps the belt 2 and feeds the belt forward, and the belt overcomes the gravity of the counterweight block and drives the first moving bracket 1033; in this application, a very heavy counterweight block will not be selected, and the weight of the counterweight block is selected such that the belt can relatively easily drive the first moving bracket 1033; for example, the weight of the counterweight block is selected to be 1 kg. In this solution, separating the first moving bracket 1033 and the second moving bracket 1034 can further avoid the occurrence of interference between the belt feeding roller group 201 and the synchronous belt assembly 301 during the belt feeding process.

[0064] Preferably, a photoelectric induction sheet 1038 is provided on the first moving bracket 1033, and a photoelectric sensor is provided on the frame body; when the first moving bracket 1033 is in the first position, the photoelectric induction sheet 1038 triggers the photoelectric sensor. The principle of the photoelectric induction sheet 1038 and the photoelectric sensor is the same as that of the triggering device 106, and is used for the controller to detect whether the reset of the first moving bracket 1033 is completed.

[0065] Preferably, a shock pad 1040 is provided between the first moving bracket 1033 and the second moving bracket 1034, and the shock pad 1040 is fixed on the first moving bracket 1033 or the second moving bracket 1034; to avoid noise generated by the impact between the first moving bracket 1033 and the second moving bracket 1034.

[0066] The locking device 1012 on the tape reel assembly is an electromagnetic brake, and the function can be switched by energizing or de-energizing.

[0067] A banding machine includes the tape storage mechanism 10 as described above, and further includes:

[0068] A frame body 1 for providing a carrier for the remaining mechanisms and components; the frame body serves as the main structure of the banding machine;

[0069] A tape storage mechanism 10 for storing the tape and supplying the tape to the knotting mechanism when needed;

[0070] A knotting mechanism 20 for advancing the tape along an annular track and forming a head-to-tail connected knot; the knotting mechanism 20 is the same as the prior art and will not be elaborated in this application; in this application, the knotting mechanism is installed on the left side of the frame body, and the tape storage mechanism 10 is installed on the right side of the frame body, and the overall height is reduced;

[0071] A tightening mechanism 30 for reversely tightening the tape and tightly binding the knot formed by the tape to the product to be banded;

[0072] A fusion welding mechanism 40, which is used to weld the head and tail ends of the loop together; the fusion welding mechanism 40 is the same as the prior art, and will not be elaborated in this application;

[0073] A tape cutting mechanism 50, which is used to cut the tape connected to the loop; the tape cutting mechanism 50 is the same as the prior art, and will not be elaborated in this application;

[0074] Among them, the moving component 103, the detection roller 104, the detection bracket 105 and the triggering device 106 cooperate to form a tightening mechanism 30.

[0075] A packing method for a bundling machine, which is based on the said bundling machine, and its specific steps include:

[0076] Step (1), in the initial state, the tape storage mechanism 10 stores tape normally, and the tape reel 1011 is in a locked state;

[0077] Step (2), perform a tape feeding action: the tape feeding roller group 201 clamps the tape 2 and feeds it forward. When the tape is in a taut state, it transmits force to the moving roller 1031, and the moving roller and the moving component 103 move from the first position to the second position; combined with Figure 1 the state shown in, the moving component 103 moves from left to right; after the moving roller 1031 moves a certain distance, the tape feeding ends; when the tape feeding ends, the position where the moving roller 1031 is located is generally the middle position of the entire moving length;

[0078] Step (3), the front end of the tape is pressed; the pressing structure is the prior art and is realized by the configured top knife mechanism 60; the top knife mechanism 60 is the prior art. A tape passing groove is provided in the middle of the top knife of the top knife mechanism, and the tape passes through the tape passing groove before forming a loop; the top of the top knife is used to press the tape;

[0079] Step (4), perform a tape retracting action: the tape feeding roller group 201 releases the tape, and the moving component 103 moves to the first position; the driven wheel of the tape feeding roller group disengages from the tape, and the tape is pulled away by the first moving bracket 1033; during the moving process, the moving roller retracts the tape back into the tape storage mechanism, and the tape gradually tightens; since the loop forming mechanism has used a part of the tape and the tape reel is in a locked state, the length of the tape makes the moving component unable to retract to the first position; when the tightening force of the tape gradually increases to the set value, the detection roller 104 is driven by the tape, and the detection roller drives the detection bracket 105; the triggering device 106 on the frame detects the action of the detection bracket, and the triggering device indirectly or directly controls the locking device 1012 of the tape reel, so that the tape reel 1011 can rotate;

[0080] Step (5), perform the tape storage action: The tape feeding roller group 201 clamps the tape, the moving component 103 continues to move towards the first position, the tape reel rotates and supplies the tape into the tape storage mechanism until the tape storage is completed;

[0081] Step (6), the tape cutting mechanism 50 completes tape cutting, and the welding mechanism 40 completes tape welding; The packaging is completed.

[0082] In the said step (1), in the initial state, as Figure 6 shown, the first moving bracket 1033 and the second moving bracket 1034 are in a separated state. The first moving bracket 1033 is located at the first position or slightly displaced from the first position under the action of the counterweight 1036, and the second moving bracket 1034 is located at the second position; The second moving bracket 1034 is located on the right side and abuts against the swing arm;

[0083] In the said step (2), the moving roller 1031 and the first moving bracket 1033 overcome the gravity of the counterweight, and both the moving roller and the first moving bracket 1033 move a certain distance towards the second position, and the tape feeding ends;

[0084] In the said step (4), the first moving bracket 1033 moves towards the first position under the action of the counterweight; The second moving bracket 1034 moves towards the first position under the action of the synchronous belt assembly and the drive motor. If the rotational speed of the drive motor is relatively fast, the second moving bracket 1034 can catch up with the first moving bracket 1033 during the movement of the first moving bracket 1033; When the first moving bracket 1033 moves towards the first position to a certain extent, the tape is in a taut state, and the tape that is fed more in the tape feeding step has all been retracted into the tape storage mechanism 10; The tension force of the tape acts on the detection roller. When the force of the tape reaches the force set by the electromagnetic damper, the detection roller drives the swing arm to act, and the sensor at the upper end of the swing arm is triggered; In the actually designed scheme, the gravity of the counterweight is not sufficient to drive the swing arm, and the second moving bracket 1034 is required to push;

[0085] In the said step (5), the second moving bracket 1034 continues to move towards the first position and pushes the first moving bracket 1033 towards the first position; The tape reel rotates to store the tape until the first moving bracket 1033 reaches the first position; When the first moving bracket 1033 reaches the first position, the first moving bracket 1033 triggers a photoelectric signal; The electromagnetic brake locks the tape reel again; The drive motor 303 drives the synchronous belt assembly to rotate in the reverse direction according to this photoelectric signal, and the second moving bracket 1034 moves towards the second position and pushes the detection bracket 105 to reset; When the detection bracket reset is completed, the sensor on the frame is triggered, and the tape storage is completely completed; The work is completed.

[0086] As a variation of the method, in step (5), after the tape feeding roller group 201 clamps the tape, steps (6) and the remaining actions of step (5) can be executed simultaneously; specifically, after the tape feeding roller group 201 clamps the tape, the controller controls the top knife of the top knife mechanism 60 to move upward and hold the tape, the cutter of the tape cutting mechanism moves upward and cuts the tape, and the hot knife of the welding mechanism realizes the welding of the bundled tape; after the top knife, the cutter, and the hot knife are executed, they are reset; then the reset of the detection bracket 105 is executed. It should be noted that in this method, the tape reel is locked first and then the swing arm is reset. Therefore, during the reset process of the swing arm, the first moving bracket 1033 will move slightly to the right, which is a normal phenomenon and also falls within the protection scope of this application. The specific structures of the top knife, the cutter, and the hot knife belong to the prior art.
