Processing apparatus for processing subject

1. A processing apparatus for unfurling or folding a processing subject, comprising:

a pair of retaining devices capable of retaining the processing subject;

a carrying device capable of carrying the processing subject such that a part of the processing subject hangs down therefrom while the processing subject is retained by at least one of the pair of retaining devices; and

a control device that controls movement of the retaining devices and the carrying device,

wherein the control device rotates the carrying device in a condition where the processing subject retained by at least one of the retaining devices hangs down from the carrying device,

wherein, in a condition where the processing subject retained by at least one of the retaining devices hangs down from the carrying device, the control device tilts the carrying device at a predetermined angle relative to a vertical direction of the processing apparatus during unfurling the processing subject.

2. The processing apparatus according to claim 1 , wherein, in a condition where the processing subject is retained by a first retaining device of the pair of retaining devices so as to hang down from the carrying device, the control device causes a second retaining device of the pair of retaining devices to retain a lowermost point of the processing subject by moving the second retaining device below the processing subject.

3. The processing apparatus according to claim 1 , wherein, when the retaining devices move above the carrying device while lifting up the processing subject, the control device brings a part of the carrying device into contact with the processing subject either by moving the carrying device in a horizontal direction toward the retaining devices or by rotating the carrying device.

4. The processing apparatus according to claim 1 , wherein the carrying device is a rectangular plate-shaped member, and

the control device tilts the carrying device relative to the horizontal direction, and then places the processing subject, which is retained by both of the pair of retaining devices, on an edge line of the carrying device.

5. The processing apparatus according to claim 1 , further comprising a pair of clamping members that move relative to the carrying device in order to clamp the carrying device carrying the processing subject.

6. The processing apparatus according to claim 5 , wherein the clamping members clamp the carrying device such that the part of the processing subject that hangs down from the carrying device is folded toward the carrying device.

7. The processing apparatus according to claim 1 , further comprising an imaging device that photographs the processing subject while the processing subject is retained by the retaining devices,

wherein the control device controls the movement of the retaining devices and the carrying device on the basis of image data obtained from the imaging device in relation to the processing subject.

8. The processing apparatus according to claim 7 , wherein the control device includes:

an end point detection unit that detects a lowermost point of the processing subject on the basis of the image data obtained from the imaging device in relation to the processing subject; and

a retaining device control unit that causes a first retaining device of the pair of retaining devices to retain the processing subject, and in this condition moves a second retaining device of the pair of retaining devices toward the processing subject and causes the second retaining device to retain the lowermost point.

9. The processing apparatus according to claim 7 , wherein the control device includes a type recognition unit that recognizes a type of the processing subject on the basis of the image data obtained from the imaging device in relation to the processing subject.

10. A processing apparatus for unfurling or folding a processing subject, comprising:

a pair of retaining devices capable of retaining the processing subject;

a carrying device capable of carrying the processing subject such that a part of the processing subject hangs down therefrom while the processing subject is retained by at least one of the pair of retaining devices, wherein the carrying device is tilted at a predetermined angle relative to a vertical direction during unfurling the processing subject; and

a control device that controls movement of the retaining devices and the carrying device,

wherein, in a condition where the processing subject retained by at least one of the retaining devices hangs down from the carrying device, the control device moves the retaining devices in a horizontal direction relative to the carrying device or moves the carrying device in the horizontal direction relative to the retaining devices such that a lowermost point of the processing subject is within a detection range of an end point detection unit that detects a predetermined end point of the processing subject when the lowermost point of the processing subject is not within the detection range.

11. A processing apparatus for unfurling or folding a processing subject, comprising:

a pair of retaining devices capable of retaining the processing subject;

a carrying device capable of carrying the processing subject such that the processing subject hangs down therefrom while the processing subject is retained by at least one of the pair of retaining devices; and

a control device that controls movement of the retaining devices and the carrying device,

wherein the carrying device includes a rotary axis in approximate horizontal direction,

wherein the processing subject is hanged down from a first side to a second side such that the processing subject is crossed to the rotary axis,

wherein the control device rotates the carrying device in a condition where the processing subject retained by at least one of the retaining devices hangs down from the carrying device such that a part of the processing subject remaining on the second side is hoisted up and moved so that the entire processing subject including the part is moved to the first side.
