Binding machine
A reinforcing steel bar binding machine is provided with: a second body part; a cover guide part attached to the second body part; and a first contact member (a second contact member) that is abutted against a reinforcing steel bar and moved. The cover guide part is provided with: a first guide recessed part and a second guide recessed part that movably guide the first contact member; and a first contact part against which the reinforcing steel bar is abutted.
1. A binding machine comprising:
a body part;
a cover guide part attached to the body part;
a first guide and a second guide extending in a first direction from one end portion of the body part, arranged with an interval, in which a binding object is inserted, in a second direction orthogonal to the first direction, and configured to guide a wire for binding the binding object;
a slider that is abutted against the binding object inserted between the first guide and the second guide and moved from a standby position to an actuation position;
a guide moving part configured to change the interval from a first distance to a second distance shorter than the first distance in response to a movement of the slider to the actuation position;
a sensor that detects a movement of the slider to the actuation position;
a controller configured to cause the binding machine to automatically execute an operation of binding in response to a detection, by the sensor, of the movement of the slider to the actuation position; and
a cover part attached to the cover guide part, wherein the cover guide part includes:
a guide configured to movably guide the slider;
a contact part against which the binding object is to be abutted;
a first sidewall part positioned at one side of the body part;
a second sidewall part positioned at another side of the body part; and
a connection part connecting the first sidewall part and the second sidewall part,
wherein the first sidewall part and the second sidewall part include a moving support point of the guide moving part,
wherein one of the guide and the slider includes a guide concave portion, which includes a long hole-shaped opening, which opens in a direction orthogonal to a moving direction of the slider, the guide concave portion including walls on both sides in the moving direction of the slider, the guide concave portion extending in a moving direction of the slider, and the walls extending in the direction orthogonal to the moving direction to restrict the range of movement of the slider in the moving direction,
wherein the other of the guide and the slider includes a guide convex portion protruding in the direction orthogonal to the moving direction and inserted into the guide concave portion, the guide convex portion being capable of abutting the walls,
wherein the slider covers the cover guide part and a moving amount of the slider is defined by the cover guide part, and
wherein the cover part covers the slider, and a guide concave portion and a guide convex portion are provided between the slider and the cover part.
2. The binding machine according to claim 1 , wherein the cover guide part covers the body part in at least three directions.
3. The binding machine according to claim 1 , wherein the cover part is configured to cover the guide and to be detachably attached to the cover guide part.
4. The binding machine according to claim 1 , wherein the guide configured to movably guide the slider comprises a plurality of guides provided at a plurality of positions on the same axis along the moving direction of the slider.
5. The binding machine according to claim 1 , wherein the slider comprises a pair of sliders, and the cover guide part is configured so that the pair of sliders can independently move.
6. The binding machine according to claim 1 , wherein the cover part covers the guide concave portion.
7. The binding machine according to claim 1 , wherein the moving support point of the guide moving part is provided on both of the first sidewall part and the second sidewall part of the cover guide part.
