Abstract
A sheet material feeding apparatus includes a first roll 106, and a second roll 108 arranged vertically below first roll 106, to feed a sheet material clamped between the first roll 106 and the second roll 108. The sheet material feeding apparatus further includes a first motor 102 provided with a rotatable first motor shaft 104 coupled to the first roll 106, and a second motor 103 provided with a rotatable second motor shaft 105 coupled to the second roll 108. The first motor shaft 104 and the second motor shaft 105 rotate at substantially the same rotation speed to allow the first roll 106 and the second roll 108 to rotate in synchronization with each other.
Claims13
A sheet material feeding apparatus, comprising:
- a housing;
- a first roll accommodated in the housing;
- a second roll accommodated in the housing and arranged vertically below the first roll;
- a first motor provided with a rotatable first motor shaft coupled to the first roll;
- a second motor provided with a rotatable second motor shaft;
- a joining device that couples the second roll and the second motor shaft to allow the second roll to be movable vertically with respect to the second motor shaft;
- a roll support member that is vertically movable and supports the second roll, the roll support member including a cam bearing at a lower end thereof;
- a cam piston that is movable in a direction which is horizontal and orthogonal to a rotational axis of the second roll, and engages with the cam bearing to move the roll support member vertically as the cam piston moves horizontally;
- and
- an eccentric cam configured to move the cam piston horizontally as the eccentric cam rotates,
- wherein a sheet material is fed while clamped between the first roll and the second roll and, while the sheet material is clamped, the eccentric cam is rotated to move the cam piston horizontally and the roll support member vertically to release the sheet material, and
- the first motor shaft and the second motor shaft rotate at substantially the same rotation speed to allow the first roll and the second roll to rotate in synchronization with each other.
