Battery powered tensioning tool for strap

摘要

A tensioner for strap includes a housing, a battery, a motor, a tension head having a tension wheel operably connected to the motor and a nosepiece having a pinch element. The nosepiece is mounted to the tension head for movement relative thereto. An actuator handle is mounted to the nosepiece to move the pinch element toward and away from the tension wheel. A strap sensor is operably connected to a controller and senses the presence or absence of strap between the tension wheel and the pinch element. A home position switch senses pinch wheel proximity to the tension wheel. The nosepiece is moved away from the tension head to introduce strap to the tool and the home position switch changes state to signal the controller to permit actuation of the motor when the strap sensor senses the presence of strap between the pinch element and the tension wheel.

1. A tensioner for strap, comprising:
a housing; a local power supply removably mounted to the housing; a motor positioned in the housing; a tension head mounted to the housing; a tension wheel positioned in the tension head, the tension wheel operably connected to the motor; a nosepiece operably mounted to the tension head for movement relative to the tension wheel, the nosepiece including a pinch element, the nosepiece being biasedly mounted to bias the pinch element toward the tension wheel; an actuator handle operably connected to the nosepiece to move the pinch element toward and away from the tension wheel; a strap sensor located in the tension head and positioned to sense the presence and/or absence of strap between the tension wheel and the pinch element; a home position switch; a home position switch engaging element for engaging the home position switch when the pinch element is in proximity to the tension wheel; and a controller positioned in the housing and operably connected to the strap sensor and the home position switch, wherein when the nosepiece is moved away from the tension head to introduce strap between the tension wheel and the pinch element, the home position switch engaging element disengages from the home position switch changing the state of the home position switch to signal the controller to permit actuation of the motor when the strap sensor senses the presence of strap between the pinch element and the tension wheel.
