Description

The present invention relates to an inkjet printer provided with a wiping mechanism for cleaning the nozzle surface with a simple structure.

In an inkjet printer having a head that ejects a liquid such as ink, the printing quality is improved by keeping the nozzle surface on which the nozzle that ejects the liquid is arranged clean.

FIG. 7 is an explanatory view of an aspect of the nozzle surface cleaning mechanism in the conventional inkjet printer 101. In the inkjet printer 101, the head portion 105 has a plurality of inkjet heads 115 that are scanned on the Y-direction stretching member (Y bar) 107 to eject a liquid such as ink. A mounting table 117 is arranged so as to face the head portion 105. The object to be printed 109 is placed on the mounting table 117, and is printed by ink or the like ejected from the inkjet head 115. The operation of the head unit 105, the printed object 109, and the like is controlled by the control unit 129. A method is known in which the nozzle surface 111 is wiped with a wiper 113 when the head portion 105 is moved in the X direction in the nozzle surface cleaning region 121 to keep the nozzle surface clean. Specifically, for example, by moving the nozzle surface 111 of the head portion 105 in contact with the wiper 113, the ink or the like adhering to the nozzle surface 111 is wiped off.

In addition to the simple wiper mechanism described above, various techniques have been proposed for a cleaning mechanism for wiping the nozzle surface 111. For example, a technique is also known in which a cylinder wrapped with a cloth for wiping is appropriately rotated by a driving device to expose a clean cloth portion and wipe the nozzle surface 111 (see, for example, Patent Document 1). ..

When moving the cleaning mechanism with the head fixed, two drives are required: a drive device that moves the cleaning mechanism and a drive device that exposes a new surface of the wiping member that wipes the nozzle surface. In some cases. If there are a plurality of drive devices in this way, the control of each device becomes complicated, and the cost increases due to the increase in the number of parts, which is not preferable.
Further, in the technique described in Patent Document 1, although only one drive device is required, there is a problem that a complicated planetary gear switching mechanism is required and a failure is likely to occur.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an inkjet printer provided with a cleaning mechanism capable of reliably cleaning a nozzle surface with a small number of parts.

In an inkjet printer, excess ink may adhere to the nozzle surface of the head where a large number of nozzle holes for ejecting ink etc. are arranged, and if left as it is, the nozzle holes may be blocked or mixed colors may occur. This causes deterioration of print quality. It is common to provide a cleaning mechanism in order to keep the nozzle surface clean, but if a plurality of drive devices are required or the mechanism is complicated, problems arise in terms of cost and ease of maintenance. Therefore, in the present invention, by combining one driving device and a joint mechanism for rotational motion, it is possible to achieve both the movement of the cleaning mechanism and the feeding control of the wiping member.

The wiping member includes a conversion member that converts the power of linear movement into the power of rotational movement, and the wiping member is covered by rotating the sheet roll, which is the wiping member that is wound and stored, in a predetermined direction. The wiping portion is advanced to a position where it can be wiped, and in the wiping member winding region, the drive source linearly moves the cassette carrier along the guide portion, and the power of the linear movement of the cassette carrier. Is converted into the power of the rotational operation by the conversion member, so that the sheet roll is rotated in the direction in which the wiping member is advanced to a position where the wiped portion can be wiped. I will provide a.

According to the invention described in (2) above, by providing the jointing mechanism, the presence or absence of winding of the wiping member, specifically, the allowance and prevention of rotation of the sheet roll, as the moving direction of the cassette carrier changes. Therefore, it is possible to achieve an excellent effect that the cassette carrier can be moved and the wiping member can be appropriately wound with only a small number of parts and one drive source.

(3) In the present invention, the joint mechanism regulates the radial movement of the sun gear, the planetary gear that rotates by being meshed with the sun gear, and the movement of the planet gear in the circumferential direction. The space has a planetary gear support gear that supports the planetary gear in the space, and the space is a planetary gear in the space when the cassette carrier is linearly moved in the first direction. Has a blocking portion that moves from one side to the other and engages with the planetary gear to prevent the planetary gear from rotating, and the blocking portion engages with the planetary gear to rotate the planetary gear. When this is prevented, the planetary gear support gear rotates with the rotation of the sun gear, and the wiping member that is wound and stored is wound to a position where the wiped portion can be wiped, and the wiped portion is wound. When the cassette carrier is linearly moved in the second direction opposite to the first direction, the planetary gear in the space moves from the other side to the one side, and the planetary gear The wiping member that allows rotation and that the planetary gears rotate freely with the rotation of the sun gears so that the rotation of the planetary gears is not transmitted to the planetary gear support gears and is wound and housed.

The wiping member 31 is moved to a position where the wiped portion can be wiped by rotating the seat roll 33, which is the wiping member 31 wound and stored, in a predetermined direction, and the wiping member is wound up. In the region 75, the drive source 60 linearly moves the cassette carrier 35 along the guide portion 45, and the power of the linear movement of the cassette carrier 35 is converted into the power of the rotational operation by the conversion member. The seat roll 33 is rotated in the direction in which the wiping member 31 is advanced to a position where the wiping portion can be wiped.

FIG. 5 is an explanatory diagram of a gear mechanism constituting the one-way clutch 100 which is a joint / disconnection mechanism. The gear mechanism serves to transmit rotational motion from the pinion gear 50 to the take-up gear 53 when the conditions are met.

The one-way clutch 100 includes a sun gear 90 fixedly supported by the pinion gear 50, a planetary gear lock gear 95, and a planetary gear 85 supported by the planetary gear lock gear 95 and capable of freely rotating. The planetary gear locking gear 95 is a lock pin that locks the engaged planetary gear 85 when rotating in one direction, for example, counterclockwise, and does not lock the planetary gear 85 when rotating in the opposite direction, for example, clockwise. The gear portion (blocking portion) 97 is provided (see FIG. 6 described later). The sun gear 90 and the pinion gear 50 are fixedly connected by a drive shaft.

The one-way clutch 100 is, for example, in the moving direction of the cassette carrier 35 in FIG. 4 (B), that is, when the cassette carrier 35 moves from the wiping operation region 80 to the wiping member winding region 75, the counter in FIG. When the pinion gear 50 rotates clockwise, the planetary gear 85 is locked by the planetary gear locking gear 95, and the rotational movement of the pinion gear 50 is the planetary gear locking gear via the sun gear 90 and the planetary gear 85. Reported to 95. Then, the rotational motion is transmitted from the planetary gear lock gear 95 to the take-up gear 53, and the wiping member 31 (see FIG. 4B) is taken up.

On the contrary, the one-way clutch 100 has a moving direction of the cassette carrier 35 in FIG. 4C, and when the set carrier 35 moves from the wiping member winding area 75 to the wiping operation area 80 in FIG. 4C, When the pinion gear 50 rotates clockwise, the planetary gear 85 moves in the space 96 to the opposite side of the claw portion 97 of the planetary gear locking gear 95, so that the planetary gear 85 is not locked by the claw portion 97 and is free as it is. It rotates (see FIG. 6B described later). Therefore, the rotational movement of the pinion gear 50 is not transmitted to the planetary gear locking gear 95, and as a result, the wiping member 31 is not wound up and is left in a fixed state.

FIG. 6A shows a detailed view of the one-way clutch 100. When the sun gear 90 is rotated counterclockwise (in the direction of the solid line arrow), the planetary gear 85 moves in the space 96 toward the claw portion 97 while rotating, and is caught by the claw portion 97 to be locked. The planetary gear lock gear 95 having the claw portion 97 is rotated counterclockwise (in the direction of the broken arrow).

FIG. 6B shows a one-way clutch 100 when the sun gear 90 is rotated clockwise. Since the planetary gear 85 moves in the space 96 and is located on the opposite side of the claw portion 97, it is not locked and freely rotates as shown by the broken line arrow. Therefore, the rotational movement of the sun gear 90 is not transmitted to the planetary gear lock gear 95.

As a connection mechanism for whether or not to transmit the rotational motion to the take-up gear of the wiping member, a one-way clutch having a planetary gear mechanism shown in FIGS. 6 (A) and 6 (B) is used, for example, a circumferential clutch. A rotation direction maintenance mechanism having a missing gear having teeth formed only at a predetermined position in the direction may be used (see Patent Document 2).
