This embodiment also discloses a method for bundling control of a steel bar bundling machine. The steps are as follows:

Step S1, the main control unit determines the set position of the switch group by detecting the signal output from each sub-switch in the switch group;

In this embodiment, referring to Table 1, when the main control unit detects that the signal output from the first sub-switch to the fourth sub-switch is 0110 level signal, it can be determined that the switch group is in the M position, that is, the gun head model switch Gear

When the main control unit detects that the signal output from the first sub-switch to the fourth sub-switch is the level signal of 0101, it can be determined that the switch group is in the L position, that is, the wire length setting gear position;

When the main control unit detects that the signal output from the first sub-switch to the fourth sub-switch is the level signal of 1111, it can be determined that the switch group is at the 0th gear, that is, the wire is formed into a loop diameter detection gear position;

In this embodiment, 5 torque setting gears are included; when the main control unit detects that the signals output from the first sub-switch to the fourth sub-switch are 1010 level signals, it can be determined that the switch group is in the torque setting gear Bit 5; when the main control unit detects that the signals from the first sub-switch to the fourth sub-switch are 1011 level signals, it can be determined that the switch group is in the torque setting gear 4th gear; when the main control unit detects the The signal output from one sub-switch to the fourth sub-switch is a level signal of 1100, it can be determined that the switch group is in the torque setting gear 3; when the main control unit detects the signal output from the first sub-switch to the fourth sub-switch It is a level signal of 1101, it can be determined that the switch group is in the torque setting gear 2nd gear; when the main control unit detects that the signal output from the first sub-switch to the fourth sub-switch is the level signal of 1110, the switch can be determined The group is in torque setting gear 1st gear.

Step S2. When the main control unit determines that the switch group is in the L-length setting gear L position, the main control unit controls the wire length of the steel strapping machine according to the work of the trigger switch, wherein the main control unit Correspondingly adjust the length of the wire output of the steel bar binding machine; when the wire length of the steel bar binding machine is set, during the wire feeding process of the steel bar binding machine, the rotation number detection device of the wire feeding motor detects the number of rotations of the wire feeding motor. The control unit calculates the current wire output according to the current number of turns of the wire feed motor. When the current wire output reaches the set wire output length, the main control unit controls the wire feed motor to stop rotating, and the steel bar binding machine outputs the corresponding length of wire.

In this embodiment, there may be n levels of wire output lengths, which are the 1st to nth levels respectively, and n may be 5, wherein the wire output length of the steel bar binding machine of each level is different. As the level increases, the wire output The length becomes longer; after the switch group is in the L position of the wire-out length setting gear, the main control unit counts the number of times the trigger switch is triggered. Each time the trigger switch is triggered, the count value is increased by 1 and the level of the wire-out length is increased by one level , When the count value reaches n, that is, the wire length level is the highest n level, then when the main control unit receives the trigger switch again, the count value will become 0, and the wire length level will switch to the first level. By operating the trigger switch, the user can select the corresponding length of the wire.

Step S3. When the main control unit determines that the switch group is in the torque setting gear, the main control unit sets the torque of the twisting wire motor according to the current torque setting gear of the switch group; or when the main control unit determines that the switch group is in torque When setting the gear, the main control unit controls the torque of the twisted wire motor according to the work of the trigger switch

In this embodiment, the torque setting gear includes 1 to 5 gears, and the main control unit sets the torque of the torsion wire motor according to the current torque setting gear of the switch group, which can be set as the gear increases, the torque Get bigger. The user can freely adjust the twisting force according to the needs of different rebar size combinations in the application site.

In this embodiment, there may be only one torque setting gear, and the main control unit controls the torque of the torsion wire motor according to the operation of the trigger switch. In this case, you can set the torque to have m levels, which are the 1st to m levels respectively. The torque of the torsion wire motors of each level is the same. As the level increases, the torque becomes larger; the switch group is in the torque setting file After the bit is set, the main control unit counts the number of times the trigger switch is triggered. Each time the trigger switch is triggered, the count value is increased by 1 and the torque level is increased by one level. When the count value reaches m, that is, the torque level is the highest level m level, Then when the main control unit receives the trigger of the trigger switch again, the count value will become 0, and the level will switch to the first level. By operating the trigger switch, the user can select the corresponding level of torque for the torsion wire motor.

Step S4. When the main control unit determines that the switch group is in the M-gear of the rebar binding machine gun head model, the main control unit selects the rebar binding machine gun head model according to the work of the trigger switch; wherein each time the trigger switch is triggered, the rebar binding machine gun The head model is selected once. If there are 4 types of steel bar machine heads to choose from, and four types of steel bar machine heads have different calibers, the main control unit will trigger the number of trigger switches when the switch group is in the gear switch of the steel bar machine head. Count, every time the trigger switch is triggered, the count value is increased by 1, and the model of the steel bar machine head is replaced by a larger caliber. When the count value reaches 4, when the current model of the steel bar machine head is the largest caliber, the main control When the unit receives the trigger of the trigger switch again, the count value will become 0, and the model of the steel bar gun head is selected as the smallest caliber.

In this embodiment, each steel strapping machine head model is configured with a set of wire-out length values. The set of wire-out length values includes multiple wire-out length values, and the number of wire-out length values in each group of wire-out length values The number is the same; as the caliber of the gun head becomes larger, each of the wire length values in the set of wire length values configured in the model of the steel head of the steel strapping machine head also becomes larger. In this embodiment, there are n levels of wire outlet lengths, from level 1 to level n corresponding to a set of n wire outlet length values from small to large in a group of wire outlet length values; Under the machine gun head model, if the gear of the switch group is in the setting position of the wire length, the main control unit controls the wire out length of the steel strapping machine according to the operation of the trigger switch to the configuration of the currently selected steel strapping machine head model.

In the case where the main control unit sets the torque of the torsion wire motor according to the current torque setting gear of the switch group, usually when the number of torque setting gears is multiple, each steel strapping machine head model is configured with a A group of torque values, the number of torque values included in a group of torque values is the same as the number of torque setting gears, and each torque value included in a group of torque values is in a one-to-one correspondence with each torque setting gear; for example, this implementation In the example, the switch group includes 5 torque setting gears, then the set of torque values configured for each steel strapping machine head model includes 5 torque values, 5 torque values and 5 torque setting gears are one One correspondence. Under the currently selected steel bar machine head type, if the switch group is in the torque setting gear, the main control unit sets the torque of the twisting wire motor to the set of torques configured for the currently selected steel bar machine head type The torque value corresponding to the torque setting gear relationship among the torque values of the wire motor; for example, the currently selected steel strapping machine head model is a 20A gun head, and the set of torque values of the 20A gun head is set to x group, The x group includes 5 torque values x1, x2, x3, x4, x5. The 5 torque values correspond to the torque setting gears from 1st to 5th gear. When the switch group is in the torque setting gear 1st gear, then The main control unit sets the torque of the twisting motor to x1.

In addition, when the main control unit sets the torque of the torsion wire motor according to the trigger switch operation, usually there is only one torque setting gear, then each type of steel bar machine head is equipped with a set of torque values, a set of torque The value includes multiple torsion values. Under the currently selected steel strapping machine head model, if the gear of the switch group is in the torque setting gear, the main control unit controls the torque of the twisted wire motor according to the work of the trigger switch.

Mechanically adjust the loop diameter of the wire output of the steel strapping machine until the wire diameter of the steel wire output from the steel strapping conforms to the current gun head model of the steel strapping machine.

In the above method of this embodiment, when the switch group is in the setting position of the wire length or the type of the rebar binding machine gun head is switched, the main control unit controls the status of each connected LED lamp according to the action of the trigger switch; specifically , When the switch group is in the setting mode of the wire length or the switch mode of the steel bar model of the steel strapping machine, the main control unit controls the combination state of the LED lights connected to it to change once each time the trigger switch is triggered; the user can quickly The determination of the currently set wire length or the currently selected type of rebar strapping machine head brings great convenience for users to use and adjust the rebar strapping machine.
