Can manufacturing device and can manufacturing method

A bottle can manufacturing device provided with:

• first and second turntables that are arranged facing each other and that are capable of intermittently rotating about a rotational axis;
• a plurality of chuck units that are provided on an outer periphery section of the turntables and that hold a bottom-ended cylindrical workpiece;
• a linear motor frame arranged between the first and second turntables;
• a tool supporting body supported on the linear motor frame with a linear motor therebetween;
• and
• a plurality of working tools that are provided on the tool supporting body and are respectively arranged facing the first and second turntables and that perform working on the workpieces, wherein
• the plurality of working tools are linearly reciprocated, via the tool supporting base, between the first and second turntables by the linear motor, and
• when performing the linear reciprocation, the plurality of working tools are made to alternately approach and move away from the first and second turntables, to thereby perform working on the workpiece.

• and
• a tool supporting base that supports a plurality of working tools for performing working on the workpieces and that is arranged facing the workpiece supporting base in the axial direction of the workpiece,
• in which the plurality of working tools are made to approach and move away from the workpiece supporting base in the axial direction of the workpieces, to thereby perform working on the workpieces supported on the workpiece supporting base, wherein
• the tool supporting base is provided with:
• a working tool unit that is made to approach and move away from the workpiece supporting base in the axial direction;
• and
• a supporting trestle that supports the working tool unit so as to be able to move in the axial direction,
• the working tool unit is provided with:
• a base that moves along the axial direction;
• and
• a tool supporting disk that is fixed on the workpiece supporting base side of the base and that has the working tool arranged thereon in the circumferential direction thereof,
• the base is provided with:
• a projecting section that extends along the axial direction;
• and
• a magnet plate provided on the outer side surface of the projecting section,
• the supporting trestle is provided with:
• a recessed groove section that engages with the projecting section so as to be able to relatively move in the axial direction;
• and
• an electromagnetic coil provided on the inner side surface of the recessed groove section, and wherein
• in a state where the projecting section is engaged with the recessed groove section, the electromagnetic coil and the magnet plate generate a thrust force to move the working tool unit in the axial direction.
