Multilayer-type sheet processing apparatus
A multilayer-type sheet processing apparatus includes processing units. Each of the processing units includes first guide members extending in an X-direction, first moving bodies arranged on the first guide members, second guide members supported to the first moving bodies and extending in a Y-direction, second moving bodies arranged on the second guide members, Y-drive mechanisms configured to drive the second moving bodies along the second guide members, work areas each arranged in a plane including the X- and Y-directions, and tools, which are arranged in the second moving bodies to be able to move close to and separate away from the work areas, and are each configured to form a processing line on a sheet arranged on a work area. The first moving body that is moved by the X-drive mechanism and the first moving bodies of the other units are coupled to each other.
1. A multilayer-type sheet processing apparatus comprising a plurality of processing units, each of the plurality of processing units comprising:
a first guide member extending in an X-direction;
a first moving body arranged so as to be movable along the first guide member;
a second guide member, which is supported to the first moving body and extends in a Y-direction orthogonal to the X-direction;
a second moving body arranged so as to be movable along the second guide member;
a Y-drive mechanism configured to drive the second moving body along the second guide member; and
a work area arranged in a plane including the X-direction and the Y-direction,
wherein the second moving body comprises a tool moveable towards and away from the work area and configured to form a processing line on a sheet arranged on the work area,
wherein the plurality of processing units are stacked so that the work areas of the plurality of processing units overlap with each other in a direction perpendicular to the X-direction and the Y-direction,
wherein the first moving body of at least one processing unit of the plurality of processing units is driven along the first guide member by an X-drive mechanism, and
wherein the first moving body that is moved by the X-drive mechanism and the first moving body of another processing unit of the plurality of processing units comprising no X-drive mechanism are coupled to each other.
2. The multilayer-type sheet processing apparatus according to claim 1 ,
wherein the plurality of processing units is at least three processing units stacked in a vertical direction, and the first moving body of the processing unit at an intermediate position is capable of being driven by the X-drive mechanism, and
wherein the first moving body of the processing unit at the intermediate position and the first moving bodies of other processing units provided on an upper side and a lower side with respect to the first moving body of the processing unit at the intermediate position are coupled to each other.
3. The multilayer-type sheet processing apparatus according to claim 1 , wherein, for at least one of the plurality of processing units,
