Description

  The present invention relates to a cap unit and an ink jet printer, and more particularly to a cap unit that moves up and down with movement of an ink jet head that includes a light irradiation lamp, and an ink jet printer that includes the cap unit.

  Conventionally, a recording sheet whose entire operation is controlled by a microcomputer and conveyed as a medium in a predetermined direction by a paper feeding device (hereinafter, a direction in which a medium such as a recording sheet is conveyed is appropriately referred to as a “sub-scanning direction”). Ink is ejected from an inkjet head that moves in a direction orthogonal to the sub-scanning direction (hereinafter, the direction orthogonal to the sub-scanning direction is appropriately referred to as “main scanning direction”). 2. Related Art Inkjet printers that perform predetermined printing on recording paper are known.

  In such an ink jet printer, the ink jet nozzle provided in the ink jet head is sealed with a cap at a standby position where the carriage on which the ink jet head is mounted is positioned at a predetermined timing such as after printing on the medium (hereinafter, “ “Sealing with a cap” is referred to as “capping”.) A cap unit is provided.

  The cap unit is raised when the carriage is positioned at the standby position to cap the inkjet nozzles, and is lowered when the carriage is separated from the standby position to release capping to the inkjet nozzles.

  As an elevating mechanism for elevating and lowering the capping unit, for example, an elevating mechanism that elevates and lowers by driving means such as a motor is known.

However, in such an elevating mechanism, it has been pointed out as a problem that an expensive driving means such as a motor has to be provided, which increases the manufacturing cost.

  As a technique for solving such a problem, a cap unit is known that is moved up and down as the carriage moves.

  Here, with reference to FIGS. 1A, 1B, and 1C, capping on an ink jet nozzle by a cap unit having a lifting mechanism accompanying movement of the carriage will be described.

  In order to capping the inkjet nozzle, the carriage 202 on which the inkjet head 200 is mounted is moved from the other side to the one side in the main scanning direction, and the carriage 202 is moved toward the standby position RP (see FIG. 1A). To do.)

  Then, immediately before the carriage 202 reaches the standby position RP, the contact member 102 erected on the cap unit 100 contacts the side surface 202a on one side of the carriage 202 (see FIG. 1B).

  When the carriage 202 further moves to one side in the main scanning direction, the base member 110 provided with the cap 108 is pressed and moved to one side in the main scanning direction.

  That is, in the cap unit 100, since the base member 110 on which the cap 108 is disposed is fixed to the support member 106 that is rotatably supported by the base portion 104, the cap unit 100 is pressed by the carriage 202. The support member 106 rotates in the direction of arrow A, and the base member 110 moves to one side in the main scanning direction while rising.

  When the carriage 202 is positioned at the standby position RP, the cap 108 in the cap unit 100 comes into pressure contact with a predetermined region S including the ink jet nozzle (not shown) in the ink jet head 200 to cap the ink jet nozzle (see FIG. 1 (c)).

  In the cap unit 100, one of the cap 108 in the main scanning direction from the contact surface 102a with the side surface 202a of the carriage 202 of the contact member 102 so that the inkjet nozzle (not shown) is reliably capped by the cap 108. The distance L2 in the main scanning direction to the side end portion 108a is the distance from the end portion Sa in the main scanning direction of the predetermined region S including the ink jet nozzle (not shown) on the lower surface of the carriage 202 to the side surface 202a of the carriage 202. It is configured to coincide with the distance L3 in the main scanning direction (see FIGS. 1E and 1F).

  Further, when the carriage 202 moves to the other side in the main scanning direction and moves away from the standby position RP, the support member 106 is rotated in the arrow B direction by the urging force of the urging means (not shown). As a result, the base member 110 moves to the other side in the main scanning direction.

At this time, as the carriage 202 moves to the other side in the main scanning direction, the base member 110 is lowered and the capping by the cap 108 to the inkjet nozzle (not shown) is released.

  By the way, an ink jet printer using an ultraviolet curable ink that is cured by irradiation with ultraviolet rays (hereinafter, “ultraviolet curable ink” is appropriately referred to as “UV ink”) is known.

  In this inkjet printer using UV ink, ink is ejected onto recording paper, and an ultraviolet irradiation lamp (hereinafter referred to as “ultraviolet irradiation lamp”) provided on a carriage for the discharged ink is appropriately referred to as “UV lamp”. The ink discharged onto the recording paper is cured by irradiating with ultraviolet rays.

  Such UV lamps are disposed on both end faces of the carriage 202 in the main scanning direction.

  That is, as shown in FIG. 1D, a UV lamp 302 is disposed on one side surface 202a of the carriage 202 in the main scanning direction, and a UV lamp 304 is disposed on the other side surface 202b.

  Therefore, in the cap unit 100 disposed in the ink jet printer using UV ink, the side surface 302a on one side in the main scanning direction of the UV lamp 302 is brought into contact with the contact surface 102a of the contact member 102, so that the carriage 202 It is comprised so that it may raise / lower with the movement of.

  In this case, the cap unit 100 considers the width W1 of the UV lamp 302 in the main scanning direction and the connection width W2 of the connecting portion between the carriage 202 and the UV lamp 302 in the main scanning direction. Is disposed.

That is, in the cap unit 100, the distance L3 from the contact surface 102a of the contact member 102 to the end portion 108a of the cap 108 is such that the end portion Sa of the predetermined region S in the main scanning direction extends in the main scanning direction of the UV lamp 302. It must be configured to coincide with the distance L4 in the main scanning direction to the side surface 302a on one side (see FIG. 1G).

  However, the connection width W <b> 2 varies due to the influence of component accuracy and mounting accuracy of the connection member that connects the UV lamp 302 and the carriage 202.

  Thereby, it is difficult to set the distance La from the end portion Sa of the predetermined region S to the side surface 302 of the UV lamp 302 to a constant value.

  For this reason, in an ink jet printer using UV ink, when an elevating mechanism accompanying the movement of the carriage 202 is used, it is not easy to reliably cap the ink jet nozzle.

Therefore, in an inkjet printer using UV ink, it is necessary to use an elevating mechanism that elevates and lowers the cap in the cap unit by a driving means such as a motor, resulting in high costs.

For this reason, there has been a demand for an ink jet printer capable of reliably capping an ink jet nozzle without incurring high costs even when a UV lamp is mounted.

  The overall operation of the inkjet printer 10 is controlled by a microcomputer (not shown) mounted in the side unit 18.

  Here, the inkjet printer 10 uses a conventionally known inkjet printer technique except that it includes a carriage 26 provided with UV lamps 32 and 34 and a cap unit 36 that moves up and down as the carriage 26 moves. Can be applied.

Therefore, in the following description, only the carriage 26 and the capping unit 36 will be described, and a detailed description of other configurations and operations to which a conventionally known technique can be applied will be omitted.

3 (a) shows a front view of the carriage, FIG. 3 (b) shows an I arrow view of FIG. 3 (a), and FIG. FIG. 4A is a front explanatory view of the capping unit, and FIG. 4B is a view taken along the arrow II in FIG. 4A.
The carriage 26 has a UV lamp 32 disposed on the right side surface 26a and a UV lamp 34 disposed on the left side surface 26b. In addition, since the conventionally well-known technique is applied about the structure of the connection part of UV lamps 32 and 34 connected to the carriage 26 and the UV lamps 32 and 34 to the carriage 26, the detailed description is abbreviate | omitted.

  Further, on the lower side of the right side surface 26 a of the carriage 26, there are a pressing member 38 that protrudes below the lower surface 26 c of the carriage 26 and a pressing member 40 that protrudes rearward from the rear surface 26 d of the carriage 26. It is arranged.

  The pressing member 38 includes a region where an abutting portion 52 (described later) of the abutting member 50 provided on the cap unit 36 abuts in front of the UV lamp 32 in the sub-scanning direction.

Further, the pressing member 40 includes a region where an abutting portion 54 (described later) of the abutting member 50 provided on the cap unit 36 abuts behind the UV lamp 32 in the sub-scanning direction. .

  In the cap unit 36, one end portion 44a of the support member 44 is rotatably disposed on a base portion 42 fixed on the base member 14 below the standby position RP.

  A base member 48 having a cap 46 disposed on the upper surface 48a is rotatably disposed at the other end 44b of the support member 44.

  The cap 46 is provided with various functions such as suctioning an inkjet nozzle (not shown) when capping, for example. The function and configuration of the cap 46 are conventionally known. Since the technology can be applied, detailed description thereof is omitted.

  The support member 44 is always urged in the direction of arrow C by an urging means (not shown) such as a spring.

  Accordingly, the base member 48 is urged from the right side to the left side in the main scanning direction by the urging force of the urging means (not shown) in the support member 44.

  An abutting member 50 is disposed on the right side surface 48b of the base member 48. The abutting member 50 is fixed to the right side surface 48b of the base member 48 at a connection portion 60 extending in the sub-scanning direction. An abutting portion 52 that extends upward and contacts the pressing member 38 is formed on the front side of 60, and is formed by extending upward on the rear side of the connecting portion 60. An abutting portion 54 that abuts on 40 is formed.

  The contact portion 52 formed on the front side of the contact member 50 and the contact portion 54 formed on the rear side of the contact member 50 are formed with a gap g1 in the sub-scanning direction. g1 is longer than the length L1 of the UV lamp 32 in the sub-scanning direction.

  The abutting portion 52 formed on the abutting member 50 is in contact with the pressing member 38 provided on the right side surface 26a of the carriage 26 when the cap unit 36 is fixed to the base member 14 below the standby position RP. It is formed so that it can contact.

The cap unit 36 is disposed on the base member 14 so that the UV lamp 32 disposed on the carriage 26 moving in the main scanning direction passes between the contact portion 52 and the contact portion 54. .

  In the above configuration, a case where the nozzle surface 30a of the inkjet head 30 is capped by the cap unit 36 in the inkjet printer 10 will be described.

  First, in order to capping the nozzle surface 30a of the inkjet head 30, the carriage 26 on which the inkjet head 30 is mounted is moved from the left side to the right side in the main scanning direction, and the carriage 26 is moved toward the standby position RP. (See FIG. 5A).

At this time, the contact member 50 of the cap unit 36 is formed such that the contact portion 52 and the contact portion 54 are formed with a gap g1 longer than the length L1 of the UV lamp 32 in the sub-scanning direction. The unit 36 is disposed on the base member 14 so that the UV lamp 32 disposed on the carriage 26 moving in the main scanning direction passes between the contact portion 52 and the contact portion 54. The contact parts 52 and 54 do not contact the UV lamp 32 (see FIG. 6A).

  Immediately before the carriage 26 reaches the standby position, the contact portions 52 and 54 of the contact member 50 of the cap unit 36 contact the pressing members 38 and 40 provided on the right side surface 26a of the carriage 26, respectively. (See FIG. 5B).

  When the carriage 26 further moves from the left side to the right side in the main scanning direction, the base member 48 is pressed and moved from the left side to the right side in the main scanning direction.

Here, since the base member 48 on which the cap 46 is disposed is fixed by a support member 44 that is rotatably supported by the base portion 42, the support member 44 is pressed by the carriage 26 against the cap 36. Rotates in the direction of arrow D, and the base member 48 moves to the right side in the main scanning direction while moving up.
When the carriage 26 is positioned at the standby position RP, the cap 46 in the cap unit 36 comes into pressure contact with a predetermined region S including the inkjet nozzle (not shown) on the nozzle surface 30a, thereby capping the inkjet nozzle (see FIG. 5 (c) and FIG. 6 (b) are referred to.)

  Here, in the inkjet printer 10, in the cap unit 36, the contact portion 52 and the contact portion 54 of the contact member 50 are formed with a gap g1 longer than the length L1 of the UV lamp 32 in the sub-scanning direction. Therefore, even if the UV lamp 32 passes over the contact member 50, the contact member 50 does not contact the UV lamp 32.

  The pressing members 38 and 40 disposed on the right side surface 26a of the carriage 26 are in contact with the contact portions 52 and 54 of the contact member 50, respectively.

For this reason, in the inkjet printer 10, the inkjet nozzle (not shown) on the nozzle surface 30 a can be reliably capped by the cap 46 in the same manner as a conventionally known inkjet printer that does not include a UV lamp. Become.

  When the carriage 26 moves from the right side to the left side in the main scanning direction and is separated from the standby position RP, the support member 44 is moved in the direction of arrow E by the urging force of the urging means (not shown). As a result, the base member 48 moves from the right side in the main scanning direction to the left side.

When the carriage 26 moves from the left side to the right side in the main scanning direction, the base member 48 is lowered and the capping by the cap 46 to the predetermined region S of the nozzle surface 30a is released.

  As described above, the inkjet printer 10 including the cap unit according to the present invention has the pressing members 38 and 40 disposed on the carriage 26 on which the UV lamps 32 and 34 are disposed, and the cap unit 36 includes The base member 48 is provided with a contact member 50 in which contact portions 52 and 54 that contact the pressing members 38 and 40 are formed.

  The pressing member 38 includes a region that contacts the contact portion 52 on the front side of the UV lamp 32 in the sub-scanning direction, and the pressing member 40 is pressed on the rear side of the UV lamp 32 in the sub-scanning direction. An area that contacts the contact portion 54 is provided.

  The contact portions 52 and 54 are formed with a gap g1 longer than the length L1 of the UV lamp 32 in the sub-scanning direction.

  Further, the cap unit 36 is disposed on the base member 14 so that the UV lamp 32 passes between the contact portion 52 and the contact portion 54 when the carriage 26 moves in the sub-scanning direction. did.

  Accordingly, in the ink jet printer 10 having the cap unit according to the present invention, the pressing members 38 and 40 can contact the contact portions 52 and 54 of the contact member 50 without contacting the UV lamp 32, respectively. It becomes.

  For this reason, in the inkjet printer 10 provided with the cap unit according to the present invention, compared with a conventionally known inkjet printer having a carriage not provided with a UV lamp, although the carriage is provided with a UV lamp. The inkjet head can be capped with the same accuracy.

Therefore, according to the ink jet printer 10 including the cap unit according to the present invention, the ink jet nozzle can be reliably capped without incurring high cost while having the UV lamp.
