Abstract
A rebar tying robot configured to tie a plurality of first rebars and a plurality of second rebars intersecting the plurality of first rebars at points where the plurality of first rebars and the plurality of second rebars intersect. The rebar tying robot may include a rebar tying machine, a conveying unit configured to convey the rebar tying machine, and a control unit configured to control an operation of the conveying unit. The conveying unit may include a crawler configured to move on the plurality of first rebars and the plurality of second rebars.
Claims14
A rebar tying robot configured to tie a plurality of first rebars and a plurality of second rebars intersecting the plurality of first rebars at points where the plurality of first rebars and the plurality of second rebars intersect, the rebar tying robot comprising:
- a rebar tying unit;
- a conveying unit configured to convey the rebar tying unit;
- and
- a control unit configured to control an operation of the conveying unit, wherein
- the conveying unit comprises a crawler configured to move in a front-rear direction on the plurality of first rebars and the plurality of second rebars,
- the conveying unit further comprises a side stepper,
- the side stepper comprises:
- a step bar;
- and
- a stepper motor configured to drive the step bar along a predetermined side- stepping track,
- when the step bar moves along the side-stepping track, a lower end of the step bar moves to a position lower than a lower end of the crawler, then the lower end of the step bar moves in a left-right direction, and then the lower end of the step bar moves to a position higher than the lower end of the crawler, and
- the step bar extends in the front-rear direction.
A rebar tying robot configured to tie a plurality of first rebars and a plurality of second rebars intersecting the plurality of first rebars at points where the plurality of first rebars and the plurality of second rebars intersect, the rebar tying robot comprising:
- a rebar tying unit;
- a conveying unit configured to convey the rebar tying unit;
- and
- a control unit configured to control an operation of the conveying unit, wherein
- the conveying unit comprises a crawler configured to move in a front-rear direction on the plurality of first rebars and the plurality of second rebars,
- the crawler comprises a right crawler and a left crawler,
- the rebar tying robot further comprises a position detection sensor configured to detect a position of a first rebar in the left-right direction to be subjected to a tying operation among the plurality of first rebars, and
- the control unit is configured to provide a speed difference between the right crawler and the left crawler so that a position of the first rebar in the left-right direction detected by the position detection sensor becomes closer to a reference position.
A rebar tying robot configured to tie a plurality of first rebars and a plurality of second rebars intersecting the plurality of first rebars at points where the plurality of first rebars and the plurality of second rebars intersect, the rebar tying robot comprising:
- a rebar tying unit;
- a conveying unit configured to convey the rebar tying unit;
- a control unit configured to control an operation of the conveying unit;
- and
- a battery holder configured to detachably receive a plurality of battery packs, each of the plurality of battery packs being a battery pack configured to be detachably attached to a rebar tying machine independent of the rebar tying robot when each battery pack is detached from the battery holder.
