PLACEMENT DEVICE, PLACEMENT SYSTEM AND PLACEMENT METHOD
First Claim
1. A placement device for placing parts of a disposable worn article on a base material, the placement device comprising:
- a base transfer device for carrying the base material;
a part transfer unit for carrying a plurality of parts separated from each other; and
two or more re-pitch units for intermittently picking up the plurality of parts from the part transfer unit and intermittently placing the plurality of parts on the base material, wherein;
each of the two or more re-pitch units includes two pads, each of which picks up one of the plurality of parts, accelerates until placing the one on the base material, and decelerates after the placement;
each of the re-pitch units includes one servo motor for rotating one of the two pads and another servo motor for rotating another one of the two pads, and does not include three or more servo motors; and
the two pads of each of the re-pitch units rotate about a common axis.

3. A placement device for placing parts of a disposable worn article on a base material, the placement device comprising:
-
a base transfer device for carrying the base material; a part transfer unit for carrying a plurality of parts separated from each other; a first unit for intermittently picking up some of the plurality of parts from the part transfer unit and intermittently placing the some of the plurality of parts on the base material; and a second unit for intermittently picking up, at a position on the part transfer unit downstream of the first unit, remaining parts that have not been picked up by the first unit from the part transfer unit and intermittently placing the remaining parts on the base material at a position on the base transfer device upstream of the first unit, wherein; the first unit includes a first pad for picking up an (i+1)th one (i is 0 or a multiple of
4) of the plurality of parts, accelerates until placing the (i+1)th one on the base material, and decelerates after the placement of the (i+1)th one;the second unit includes a second pad for picking up a (j+2)th one (j is 0 or a multiple of
4) of the plurality of parts, accelerates until placing the (j+2)th one on the base material, and decelerates after the placement of the (j+2)th one;the first unit includes a third pad for picking up an (i+3)th one of the plurality of parts, accelerates until placing the (i+3)th one on the base material, and decelerates after the placement of the (i+3)th one; the second unit includes a fourth pad for picking up a (j+4)th one of the plurality of parts, accelerates until placing the (j+4)th one on the base material, and decelerates after the placement of the (j+4)th one; the first, second, third and fourth pads are placed at the same position in a width direction perpendicular to a carrying direction of the plurality of parts; the first unit includes one servo motor for rotating the first pad and another servo motor for rotating the third pad, and does not include three or more servo motors, wherein the first pad and the third pad rotate about a common axis; and the second unit includes one servo motor for rotating the second pad and another servo motor for rotating the fourth pad, and does not include three or more servo motors, wherein the second pad and the fourth pad rotate about a common axis. - View Dependent Claims (6, 8, 9)
