Printing apparatus and can body manufacturing system
A printing apparatus ( 500 ) is provided with a moving unit ( 550 ) used to convey a can body ( 10 ). In addition, the printing apparatus ( 500 ) is provided with a first linear unit ( 610 ) in a linear shape which the moving unit ( 550 ) travels to move in one direction. Moreover, the printing apparatus ( 500 ) is provided with a second linear unit ( 620 ) which the moving unit ( 550 ) travels to move in a direction opposite to the one direction, the second linear unit ( 620 ) being arranged in parallel with the first linear unit ( 610 ) and formed linearly. Further, the printing apparatus ( 500 ) is provided with a printing unit ( 520 ) that performs printing on the can body ( 10 ) held by the moving unit ( 550 ). By these units, the miniaturization of a printing apparatus and a can body manufacturing system is attained.
1. A printing apparatus comprising:
a moving body used for conveying a can body;
a first moving route in a linear shape which the moving body travels when the moving body moves in one direction;
a second moving route disposed in parallel with the first moving route and formed in a linear shape, which the moving body travels when the moving body moves in a direction opposite to the one direction;
a third moving route that moves the moving body from one moving route of the first moving route and the second moving route to an other moving route; and
a printing unit that performs printing on a can body held by the moving body, wherein
a moving mechanism for moving the moving body in the third moving route is provided apart from a moving mechanism for moving the moving body in the first moving route and a moving mechanism for moving the moving body in the second moving route.
2. The printing apparatus according to claim 1 , wherein
the printing unit is provided to the first moving route or the second moving route, and,
in a moving route of the first moving route and the second moving route, which is provided with the printing unit, a linear mechanism is used to move the moving body.
3. The printing apparatus according to claim 1 , wherein one moving route of the first moving route and the second moving route is disposed above an other moving route.
4. The printing apparatus according to claim 1 ,
wherein
the third moving route is formed into a linear shape and is disposed in a relationship substantially orthogonal to the first moving route and the second moving route.
5. The printing apparatus according to claim 1 ,
wherein
the moving mechanism for moving the moving body in the third moving route includes a rotation body that holds the moving body, the moving mechanism rotating the rotation body around a rotation axis extending along a direction in which the first moving route and the second moving route extend to move the moving body.
6. A can body manufacturing system comprising a moving route on which a can body moves, which is branched to a plurality of branch routes at a branch part, the plurality of branch routes joining at a joining part on a downstream side of the branch part, the moving route including a joining route that is provided on a downstream side in the joining part, an inkjet printing apparatus provided to one branch route included in the plurality of branch routes, the inkjet printing apparatus performing printing onto a can body by an inkjet method; a plate printing apparatus provided to an other branch route included in the plurality of branch routes, the plate printing apparatus performing printing onto a can body by a plate printing method, and a controller adapted to cause the system to perform a common processing to the can body onto which printing has been performed by the inkjet printing apparatus and the can body onto which printing has been performed by the plate printing apparatus along the joining route.
