Abstract

An automatic cleaner for a pressing device has a pressing unit that can reciprocate between a pressing position and an apart position. The automatic cleaner includes a separating structure configured to separate a workpiece from the pressing unit; a cleaning member; and a drive mechanism configured to move the separating structure and the cleaning member back and forth, in accordance with movement of the pressing unit. The drive mechanism is configured to make the separating structure drop the workpiece, after being worked, from the pressing unit, and to make the cleaning member clean the pressing unit, in accordance with the movement of the pressing unit.

First claim

The invention claimed is:

1. An automatic cleaner for a pressing device having a pressing unit that can reciprocate between a pressing position for pressing a workpiece and an apart position apart from the pressing position, the automatic cleaner comprising:
a separating structure configured to separate the workpiece from the pressing unit;
a cleaning member; and
a drive mechanism configured to move the separating structure and the cleaning member back and forth, relative to the pressing unit, in accordance with movement of the pressing unit, wherein
the drive mechanism is configured to make the separating structure drop the workpiece, after being worked, from the pressing unit, and to make the cleaning member clean the pressing unit, in accordance with the movement of the pressing unit,
wherein
the drive mechanism includes:
a biasing member; and
a movable member biased by the biasing member toward the pressing unit, the movable member being moved back and forth, relative to the pressing unit, in accordance with the movement of the pressing unit,

the pressing unit includes a pressing unit side inclined surface that is inclined with respect to a direction of the reciprocating movement of the pressing unit, and
by sliding the pressing unit side inclined surface and a part of the movable member on each other, in accordance with the movement of the pressing unit, the movable member is moved back and forth relative to the pressing unit.

2. An automatic cleaner for a pressing device having a pressing unit that can reciprocate between a pressing position for pressing a workpiece and an apart position apart from the pressing position, the automatic cleaner comprising:
a separating structure configured to separate the workpiece from the pressing unit;
a cleaning member; and
a drive mechanism configured to move the separating structure and the cleaning member back and forth, relative to the pressing unit, in accordance with movement of the pressing unit, wherein
the drive mechanism is configured to make the separating structure drop the workpiece, after being worked, from the pressing unit, and to make the cleaning member clean the pressing unit, in accordance with the movement of the pressing unit,
wherein
the drive mechanism includes:
a biasing member; and
a movable member biased by the biasing member toward the pressing unit, the movable member being moved back and forth, relative to the pressing unit, in accordance with the movement of the pressing unit,
the movable member includes a movable member side inclined surface that is inclined with respect to a direction of the movement of the movable member, and
by sliding a part of the pressing unit and the movable member side inclined surface of the movable member on each other, in accordance with the movement of the pressing unit, the movable member is moved back and forth relative to the pressing unit.

3. The automatic cleaner according to claim 1 , wherein
while the pressing unit moves close to the pressing position, the drive mechanism moves the separating structure and the cleaning member back from the pressing unit, and
while the pressing unit moves away from the pressing position, the drive mechanism moves the separating structure and the cleaning member towards the pressing unit.

4. The automatic cleaner according to claim 2 , wherein
the part of the pressing unit is a pressing unit side inclined surface that is inclined with respect to a direction of the reciprocating movement of the pressing unit, and
the movable member is moved back and forth, relative to the pressing unit, in accordance with the movement of the pressing unit, by sliding of the pressing unit side inclined surface and the movable member side inclined surface on each other.

5. The automatic cleaner according to claim 1 , wherein
the pressing unit includes:
a rod-shaped press member configured to press the workpiece; and
a press member support body configured to support the press member, the press member support body being formed in a tapered manner toward the workpiece, and

the pressing unit side inclined surface is an outer peripheral surface of the press member support body.

6. The automatic cleaner according to claim 1 , wherein
the pressing unit has a rod-shaped press member configured to press the workpiece, and
while the press member moves away from the pressing position, the separating structure is moved close to the press member and contacts the workpiece, so as to drop the workpiece adhering to the press member from the pressing unit.

7. The automatic cleaner according to claim 6 , wherein the separating structure has a concave portion recessed such that, when the press member moves away from the pressing position and the separating structure is in a state of being close to the press member, the separating structure does not interfere with the press member.

8. The automatic cleaner according to claim 6 , wherein while the press member moves away from the pressing position, the cleaning member contacts the press member and cleans the press member.

9. The automatic cleaner according to claim 8 , wherein while the press member moves away from the pressing position, the cleaning member cleans an outer peripheral surface and an end surface, on a side of the workpiece, of the press member.

10. The automatic cleaner according to claim 1 , wherein the cleaning member is a brush.

11. The automatic cleaner according to claim 1 , further comprising an air blowing mechanism configured to blow air to the pressing unit in the pressing position.

12. A pressing device comprising:
the automatic cleaner according to claim 1 ;
the pressing unit; and
a pressing unit moving mechanism configured to reciprocate the pressing unit between the pressing position and the apart position.
