Abstract

A printing apparatus including: a cleaning section including a cleaning member and configured to perform cleaning processing of a screen mask used in printing of a viscous fluid onto a print target; a cleaning member moving section configured to perform at least one of moving the cleaning member to and from a cleaning position and an exchange position, and unloading and loading of the cleaning member; and an exchange control section configured to control the cleaning member moving section to perform cleaning member exchange processing of exchanging the cleaning member.

First claim

The invention claimed is:

1. A printing apparatus comprising:
a cleaning section including a cleaning member and configured to perform cleaning processing of a screen mask used in printing of a viscous fluid onto a print target;
a cleaning member moving section configured to perform at least one of moving the cleaning member to and from a cleaning position and an exchange position, and unloading and loading of the cleaning member;
a holder that holds an exchange-cleaning member; and
an exchange control section configured to control the cleaning member moving section to perform cleaning member exchange processing of exchanging the cleaning member with the exchange-cleaning member.

2. The printing apparatus according to claim 1 , wherein
the cleaning section includes an attachment member configured to have the cleaning member attached and including an engaging member configured to engage with the holder, wherein
the cleaning member moving section, by moving the cleaning member, moves the cleaning member to and from the cleaning position and the holder, and
the exchange control section is configured to, during the cleaning member exchange processing, control the cleaning member moving section to exchange the attachment member together with the cleaning member to and from the holder and the cleaning section.

3. The printing apparatus according to claim 2 , wherein
the cleaning section includes a loading member on which the attachment member is loaded, and a support member configured to support the loading member from a first direction along a horizontal direction,
the cleaning member moving section includes a mechanism configured to move the cleaning member by moving the support member in a second direction that is along the horizontal direction and perpendicular to the first direction, and a mechanism configured to relatively move the loading section with respect to the support member in the second direction,
the engaging section includes a protruding section protruding from the attachment section at both sides in the first direction, and
the exchange control section is configured to, during the cleaning member exchange processing, control the cleaning member moving section such that when the attachment member is transferred to and from the holder, the loading member protrudes with respect to the support member at a side of the holder in the second direction.

4. The printing apparatus according to claim 2 , wherein
the printing apparatus includes the holder and a raising and lowering section of the holder and is configured to perform loading and unloading of the attachment member to and from an accommodation apparatus configured to accommodate an exchange-use attachment member, and
the exchange control section is configured to, during the cleaning member exchange processing, by using the raising and lowering section to raise and lower the holder, perform at least one of causing the engaging section of the attachment member including the cleaning member to engage with the holder such that the attachment member is attached to the holder, or release the engagement of the engaging section of the attachment member attached to the holder from the holder to attach the engaging section to the cleaning section.

5. A printing apparatus comprising:
a cleaning section including a cleaning member and configured to perform cleaning processing of a screen mask used in printing of a viscous fluid onto a print target;
a cleaning member moving section configured to perform at least one of moving the cleaning member to and from a cleaning position and an exchange position, and unloading and loading of the cleaning member; and
an exchange control section configured to control the cleaning member moving section to perform cleaning member exchange processing of exchanging the cleaning member, wherein
the cleaning member is a wiping sheet configured to clean by being wiped on the screen mask,
the cleaning section includes a feeding section configured to feed the wiping sheet and a takeup section configured to take up the wiping sheet, and is configured to perform the cleaning processing using a portion of the wiping sheet fed by the feeding section, and to perform sheet feeing processing of using the feeding section to feed the portion of the wiping sheet used to perform the cleaning processing,
further provided is a detection section configured to detect an exchange timing at which the wiping sheet is taken to have run out, and
the exchange control section is configured to perform the cleaning member exchange processing when the detection section has detected the exchange timing.

6. The printing apparatus according to claim 1 , wherein
the exchange control section is configured to perform at least a portion of the cleaning member exchange processing in parallel with the printing.

7. A printing system comprising:
a cleaning section including a cleaning member and configured to perform cleaning processing of a screen mask used in printing of a viscous fluid onto a print target;
a cleaning member moving section configured to perform at least one of moving the cleaning member to and from a cleaning position and an exchange position, and unloading and loading of the cleaning member;
an exchange control section configured to control the cleaning member moving section to perform cleaning member exchange processing of exchanging the cleaning member; and
an accommodation apparatus configured to accommodate an exchange-use cleaning member and to enable unloading and loading of the cleaning member to and from the printing apparatus.
