Definitions
- the present invention relates to a rechargeable power tool.
- NiCd batteries and NiMH batteries are the most popular secondary batteries used in rechargeable power tools, but this type of secondary battery can be charged in a shallow depth of discharge that does not reach full discharge. Repeatedly, it is known that the power supply stops at a shallow depth of discharge during use, and there is a memory effect that reduces the apparent battery capacity.
- One or more embodiments of the present invention provide a memory effect of a secondary battery and a low temperature environment. Provide rechargeable power tools that eliminate inconveniences such as inability to use or reduction of available time.
- a rechargeable power tool using a secondary battery as a power source has a voltage threshold at which the rechargeable power tool can operate!
- a voltage comparison device that compares the power supply voltage and a warning device that displays a warning according to the comparison result are provided.
- the warning device displays a warning and the warning Even after the display, it can be started by operating the trigger switch.
- the rechargeable power tool can be applied to the motor even after the power supply voltage drops below the reference voltage and a warning is displayed by a buzzer or LED. Control is not performed to cut off the power supply, and the startup operation is accepted.Therefore, the work can be performed at least several times after the warning, and the battery can be replaced when the separation is good based on the operator's judgment rather than the machine's judgment. . Work is also possible when a warning is displayed due to an apparent voltage drop at low temperatures, which improves usability and work efficiency compared to a configuration in which the power supply to the motor is cut off at the same time as the warning is displayed. .
- FIG. 1 is a side view of a reinforcing bar binding machine.
- FIG. 2 is a flowchart showing an operation sequence of the reinforcing bar binding machine of the present invention.
- FIG. 1 shows a reinforcing bar binding machine 1 as an example of an electric tool powered by a secondary battery, and a binding wire feeding mechanism 3 and a binding wire twisting mechanism 4 are built in a housing 2.
- a binding wire reel (not shown) is loaded into the magazine 6 arranged in front of the grip portion 5 of the housing 2.
- a battery pack 7 containing a NiMH battery is attached to the end of the grip portion 5, and the feed motor of the binding wire feed mechanism 3 and the torsion motor of the binding wire twist mechanism 4 through a power circuit board (not shown). And power.
- a power switch 8, a voltage warning LED 9, and a torsion torque setting dial 10 are arranged on the upper surface of the rear part of the reinforcing bar binding machine 1, and a buzzer for voltage warning (not shown) is provided in the housing 2. Is installed.
- the reinforcing bar binding machine 1 executes the initialization operation, and the binding wire feed mechanism 3 moves the binding wire to the upper wire guide nose.
- the cable is fed by a certain length toward the wire 11 and the binding wire twisting mechanism performs a series of operations consisting of 4 forces S clamp and twist, stops at the initial position, and enters the standby state.
- the rebar binding operation of one cycle consisting of binding wire feed, binding wire clamp and binding wire pull back, binding wire cutting, and binding wire twisting is continuously executed. .
- the binding wire feed mechanism 3 is arranged in the front and back direction of the paper surface in FIG. 1 and drives one V-groove gear of the two V-groove gears that are in contact with each other by a feed motor. It is configured to feed the binding wire with an attached gear, and the binding wire is fed from the binding wire reel in the magazine 6. It is sent out upward.
- the sent-out binding wire is formed into an arc shape along the guide groove on the inner periphery of the wire guide nose 11 and goes around the reinforcing bar, and the tip is fed into the binding wire twist mechanism 4.
- the binding wire twisting mechanism 4 is composed of a twisting shaft not shown in the figure and three clamp plates attached to the tip of the twisting shaft.
- the three clamp plates are a wire guide nose 11 and a lower guard.
- the two clamp plates located on both sides of the central clamp plate are opened and closed by the cam mechanism inside the side cover 14 located between the two.
- the binding wire is sent through between the central clamp plate and one outer clamp plate, and the control unit (not shown) stops the wire feed after sending the wire corresponding to the set number of turns. At this time, the tip of the wire reaches the tip of the wire guide nose 11. Then, after the twisting shaft of the wire twisting mechanism 4 and the clamp plate move forward and grip the wire loop, the wire is pulled back, and the wire cutter (not shown) force is interlocked with the forward movement of the twisting shaft. The trailing end of the wire is cut and the wire loop is also disconnected from the subsequent wire force. At the same time, grip the rear end of the wire.
- the control unit monitors the voltage of the battery pack 7 during the bundling operation via the voltage detection circuit, and sounds a buzzer when the voltage of the battery pack 7 drops to a predetermined recommended charging voltage. Voltage warning LED9 is lit to notify the voltage drop.
- Fig. 2 shows an operation sequence of the reinforcing bar binding machine 1.
- the initialization operation (Step 2) described above is executed to enter the standby state, and the trigger lever 12 Is pulled and trigger switch is turned on (Step 3), 1-cycle bundling operation is performed and the voltage of battery pack 7 is detected (Step 4), and the battery voltage is set to the specified reference voltage (recommended charging voltage) (Step 5). If the battery voltage is equal to or higher than the reference voltage, the process returns to step 3 to execute the bundling operation by the next trigger operation.
- the rebar binding machine 1 of the present invention differs from the conventional type in that when the knotter voltage drops below the reference voltage, a warning is given but the power supply to the motor of the bundling mechanism is not interrupted. . Therefore, even when the voltage warning is displayed (step 6), if the trigger lever 12 is pulled, the bundling operation after step 3 is executed.
- the reinforcing bar binding machine can bind at least several times after the warning is displayed, and is separated by the operator's judgment rather than the machine side judgment. You can replace the battery pack at a good time.
- the reinforcing bar binding machine may not be activated without stopping power supply to the motor due to an apparent voltage drop at an extremely low temperature.
- the bundling work can be performed ignoring the warning, and it is easy to use.
- a sound buzzer or light LED has been described as a warning device.
- the technical scope of the present invention may be such that a warning is given by a voltage meter, a liquid crystal display, or a red mark display.
- a warning is given by a voltage meter, a liquid crystal display, or a red mark display.
- the present invention extends to those modifications. Needless to say, the present invention is not limited to the reinforcing bar binding machine but can be applied to power tools other than the reinforcing bar binding machine.
