Claims (5)

  1. A reel comprising a bobbin and a wire wound around the bobbin, A reel mounting section for rotatably mounting the aforementioned reel, A feeding unit that feeds the wire wound on the bobbin around the reinforcing bar, A twisted portion that twists the wire around the reinforcing bar, A type detection unit for detecting the type of reel, It comprises the reel mounting portion, the feeding portion, the twisting portion, and a support portion that supports the type detection portion. The type detection unit detects the type of the reel before the reel rotates, in a rebar tying machine.
  2. A reel mounting section for rotatably mounting a reel which comprises a bobbin and a wire wound around the bobbin, A feeding unit that feeds the wire wound on the bobbin around the reinforcing bar, A twisted portion that twists the wire around the reinforcing bar, A type detection unit for detecting the type of reel, It comprises the reel mounting portion, the feeding portion, the twisting portion, and a support portion that supports the type detection portion. The type detection unit detects the type of the reel before the reel rotates, in a rebar tying machine.
  3. A reel comprising a bobbin and a wire wound around the bobbin, A reel mounting section for rotatably mounting the aforementioned reel, A feeding unit that feeds the wire wound on the bobbin around the reinforcing bar, A twisted portion that twists the wire around the reinforcing bar, A type detection unit for detecting the type of reel, The reel mounting portion, the feeding portion, the twisting portion, and the support portion that supports the type detection portion, A control unit configured to perform a type detection process to cause the type detection unit to detect the type of the reel, Switch 1 and A housing that defines a storage space for accommodating the aforementioned reel, The housing is equipped with a reel cover that is movably attached between a state in which the storage space is open and a state in which the storage space is closed . Before the reel rotates, the control unit, upon detecting a predetermined state via the first switch, executes the type detection process . The first switch is configured to detect whether the reel cover is in a closed state in the storage space. The control unit, before the reel rotates, detects via the first switch that the reel cover is closed to the storage space, and then executes the type detection process, in a rebar tying machine.
  4. The type detection unit, A push-button type second switch, The device comprises a switch cover positioned between the second switch and the push element when the second switch is pressed by the push element, The type detection unit distinguishes and detects the type of the reel according to the pressed state of the second switch, as described in any one of claims 1 to 3 .
  5. The type detection unit distinguishes and detects the type of the reel according to at least one of the thickness of the wire, the presence or absence of a coating on the wire, and the presence or absence of plating on the wire, as described in any one of claims 1 to 3 .

Description
