Abstract

The present disclosure may suppress adhesion of a liquid to a seal member used for moisturizing a nozzle surface. A seal member that is brought into contact with a seal position of a liquid jet head, a seal member support mechanism that supports the seal member to be movable and includes a swing member that supports the seal member to be swingable about a swing shaft extending along a first direction are provided, and in a case in which the seal member is moved in a second direction and a fourth direction as the liquid jet head of which a lower surface abuts on a head abutting position defined in the swing member moves in a third direction, the seal member is moved in a fourth direction by a distance, which is at least twice a moving distance in the second direction, and separated from the seal position.

Claims (45)

1 . A cap device that caps a liquid jet head, the cap device comprising:

a seal member that is brought into contact with a seal position defined on a side surface of the liquid jet head; and

a seal member support mechanism that supports the seal member to be movable with respect to the side surface, the seal member support mechanism including a swing member that supports the seal member to be swingable about a swing shaft along a first direction in which the seal member extends,

wherein, in the swing member,

a head abutting position where a lower surface of the liquid jet head, which is a surface different from a nozzle surface of the liquid jet head and faces a direction parallel to a second direction in which the nozzle surface faces, abuts is defined, and

in a case in which the seal member is moved in the second direction and a fourth direction in which a normal line of the side surface faces, as the liquid jet head of which the lower surface abuts on the head abutting position moves in a third direction opposite to the second direction, the seal member is moved in the fourth direction by a distance, which is at least twice a moving distance in the second direction, and separated from the seal position.

2 . The cap device according to claim 1 ,

wherein the swing member moves the seal member in the third direction and a fifth direction opposite to the fourth direction as the liquid jet head of which the lower surface abuts on the head abutting position moves in the second direction, to bring the seal member into contact with the seal position.

3 . The cap device according to claim 1 ,

wherein the seal member support mechanism includes a biasing member that biases the swing member in the third direction.

4 . The cap device according to claim 1 ,

wherein the third direction has a component in a vertical upward direction, and

a distal end of the seal member is located at a highest position in a case in which the seal member is brought into contact with the seal position.

5 . The cap device according to claim 1 ,

wherein the swing member supports at least any one of one end or the other end of the seal member in the first direction.

6 . The cap device according to claim 1 ,

wherein the seal member support mechanism includes a rotation member that is rotatably supported by the swing member, and

the rotation member is disposed at a position abutting on the lower surface of the liquid jet head at the head abutting position.

7 . The cap device according to claim 1 ,

wherein the seal member support mechanism includes a plate-shaped member having an abutting surface that abuts on the lower surface of the liquid jet head at the head abutting position.

8 . The cap device according to claim 7 ,

wherein the lower surface is formed with at least any one of a protruding portion or a recess portion, and

the abutting surface is formed with at least any one of a recess portion corresponding to the protruding portion formed on the lower surface or a protruding portion corresponding to the recess portion formed on the lower surface.

9 . A capping method of capping a liquid jet head, the capping method comprising:

via a cap device including

a seal member that is brought into contact with a seal position defined on a side surface of the liquid jet head, and

a seal member support mechanism that supports the seal member to be movable with respect to the side surface, the seal member support mechanism including a swing member that supports the seal member to be swingable about a swing shaft along a first direction in which the seal member extends,

in which a head abutting position where a lower surface of the liquid jet head, which is a surface different from a nozzle surface of the liquid jet head and faces a direction parallel to a second direction in which the nozzle surface faces, abuts is defined in the swing member,

moving, in a case in which the seal member is moved in the second direction and a fourth direction in which a normal line of the side surface faces as the liquid jet head of which the lower surface abuts on the head abutting position moves in a third direction opposite to the second direction, the seal member in the fourth direction by a distance, which is at least twice a moving distance in the second direction, to separate the seal member from the seal position.

10 . A liquid jet system comprising:

a liquid jet head; and

a cap device that caps the liquid jet head,

wherein the cap device includes

a seal member that is brought into contact with a seal position defined on a side surface of the liquid jet head, and

a seal member support mechanism that supports the seal member to be movable with respect to the side surface, the seal member support mechanism including a swing member that supports the seal member to be swingable about a swing shaft along a first direction in which the seal member extends, and

in the swing member,

a head abutting position where a lower surface of the liquid jet head, which is a surface different from a nozzle surface of the liquid jet head and faces a direction parallel to a second direction in which the nozzle surface faces, abuts is defined, and

in a case in which the seal member is moved in the second direction and a fourth direction in which a normal line of the side surface faces, as the liquid jet head of which the lower surface abuts on the head abutting position moves in a third direction opposite to the second direction, the seal member is moved in the fourth direction by a distance, which is at least twice a moving distance in the second direction, and separated from the seal position.

11 . The liquid jet system according to claim 10 , further comprising:

a head lifting/lowering device that lifts and lowers the liquid jet head along the second direction and the third direction,

wherein the head lifting/lowering device lifts and lowers the liquid jet head between a cap position at which the nozzle surface of the liquid jet head is moisturized and a purge position at which the liquid jet head is purged and at which a distance from the head abutting position is longer than a distance from the head abutting position at the cap position.

12 . The liquid jet system according to claim 10 ,

wherein the lower surface of the liquid jet head is located outside the nozzle surface in the first direction.

13 . The liquid jet system according to claim 10 ,

wherein the seal position is defined at a position on a third direction side with respect to the nozzle surface.
