Examples
As shown in fig. 4, 5, 6, and 7, the dog clutch 80 includes: the clutch comprises a fixed clutch gear 82, a sliding clutch gear 81, a clutch spring 83, an adjusting nut 84 and a clutch shaft 85, wherein the fixed clutch gear 82, the sliding clutch gear 81, the clutch spring 83 and the adjusting nut 84 are coaxially arranged on the clutch shaft 85 in sequence, the fixed clutch gear 82 is fixedly connected with the clutch shaft 85, the sliding clutch gear 81 is sleeved on the clutch shaft 85 in an empty mode, the adjusting nut 84 is connected with the clutch shaft 85 through threads, and the sliding clutch gear 81 and the fixed clutch gear 82 are axially meshed with each other under the elastic action of the clutch spring 83 through at least one inclined tooth or curved tooth.
As shown in fig. 4, 5, 6 and 7, the sensor 9 is combined with the jaw clutch 80 and the tightening mechanism 30, the sensor 9 is arranged on the end surface of the sliding clutch gear 81 and leaves a gap with the end surface of the sliding clutch gear 81 (in fig. 5, the sensor 9 is in a non-triggered state), external power is input from the driving gear 61, the driving gear 61 rotates in the direction shown in fig. 4 and 7, the driving gear 61 drives the sliding clutch gear 81, the sliding clutch gear 81 is axially meshed with the fixed clutch gear 82, the fixed clutch gear 82 is fixedly connected with the transmission gear 31 and drives the active tightening wheel 301, when the tightening tension moment of the band reaches or exceeds the friction moment generated by the preset force of the clutch spring 83, the clutch spring 83 is forced to compress, and the sliding clutch gear 81 slides along the axial direction of the clutch shaft 85 and is disengaged from the fixed clutch gear 82; if no tie is entered into the tightening mechanism 30 or before the tie is tightened, the sliding clutch gear 81 and the fixed clutch gear 82 are not disengaged axially, and no signal reversal of the sensor 9 occurs (as shown in fig. 5, the sensor 9 is in a non-triggered state); only when the tightening mechanism 30 balances the tie-up tightening force (moment) with the force (moment) set by the dog clutch 80, the sliding clutch gear 81 and the fixed clutch gear 82 are disengaged from the axial engagement, and the sensor 9 is turned back (as shown in fig. 6, the end surface gap between the sensor 9 and the sliding clutch gear 81 becomes small, and the sensor 9 is in the triggered state).
As shown in fig. 4, 5, 6 and 7, the sensor 9 detects the change in the end gap with the sliding clutch gear 81 and sends a signal to determine whether the bundling of the automatic bundling tool is successful. If the clearance between the end face of the sliding clutch gear 81 and the sensor 9 does not change in a bundling period, the sensor 9 does not generate signal inversion, namely, the bundling is judged to be failed; if the sensor 9 detects that the gap between the end face of the sliding clutch gear 81 and the sensor 9 is reduced in a bundling period, and the sensor 9 generates signal inversion, the bundling belt is tensioned, namely the bundling is judged to be successful; or when the sensor 9 detects that the gap between the end face of the sliding clutch gear 81 and the sensor 9 is reduced in a bundling period, the sensor 9 can generate signal reversion, external power is immediately stopped or is reversed even by a small angle, and the external power is started again, so that the automatic bundling tool can be tensioned for two times or more; or when the sensor 9 detects that the gap between the end face of the sliding clutch gear 81 and the sensor 9 becomes smaller in a bundling period, and the sensor 9 can generate signal reversion, external power is immediately reversed, the tensioning mechanism 30 reverses to withdraw the tail of the bundling belt, namely the tail of the bundling belt is not cut off after bundling, and when the scheme is used for not cutting off the tail of the bundling belt after bundling, the cutter 8 needs to be shortened or the cutter 8 needs to be cancelled. Turning the adjustment nut 84 sets the strap tension.
Examples
As shown in fig. 11, the motor 303 is fixedly connected with the active tightening wheel 301 of the tightening mechanism 30 (either through coupling connection or through gear indirect engagement connection), the controller 304 is electrically connected with the motor 303, when no tie enters the tightening mechanism 30, the motor 303 runs idle, the current is smaller, when the tie enters the tightening mechanism 30, the current of the motor 303 can rise under the condition of constant voltage and motor impedance and inductance, when the tie is tightened, the current of the motor 303 can be larger, a comparison value of the current is preset in the controller 304, and the controller 304 judges whether the tie enters the tightening mechanism 30 and judges whether the tie is tightened by monitoring the increase of the current of the motor 303 to a preset comparison value, and then judges whether the tie is successfully tied; or when the current from the controller 304 to the motor 303 reaches a set comparison value, the controller 304 controls the motor 303 to drive the tightening mechanism 30 to realize a secondary or more tightening function, or the controller 304 controls the motor 303 to drive the tightening mechanism to reversely rotate so as to realize that the tail of the binding belt is not cut off after the binding belt is bound.
In fig. 11, if the auxiliary tightening wheel 302 and the active tightening wheel 301 are designed with a "floating" center-to-center distance, when no tie is put into the tightening mechanism 30, the motor 303 runs idle, the current is small, when the tie is put into the tightening mechanism 30, the current of the motor 303 is increased under the condition of constant voltage and motor impedance and inductance, and when the tie is tightened, the current of the motor 303 is larger, so two comparison values can be set in the control board 304: one for determining whether a tie has entered the tightening mechanism 30 and one for determining whether auto-strapping is successful.
The signal result of the current of the controller 304 monitoring motor 303 can be qualitatively or precisely quantitatively output to a terminal device, such as a display, in a wired or wireless (bluetooth) manner; the force of the tightening mechanism 30 for tightening the ribbon is in a linear relation with the current of the motor 303 without considering the loss of mechanical efficiency, so that the value of the current of the motor 303 monitored by the controller 304 can be converted into the value output of the tightening force of the tightening mechanism 30 on the ribbon, and by utilizing the characteristic, whether the ribbon is too thin or too thick, namely, the thickness error of the ribbon can be determined.
