Detailed Description
A recording apparatus according to an embodiment of the liquid ejecting apparatus of the present invention will be described in detail below with reference to the drawings.
First, an outline of the recording apparatus 1 according to an embodiment of the present invention will be described.
Fig. 1 is a schematic perspective view of a recording apparatus 1 of the present embodiment. Fig. 2 is a schematic plan view of the recording apparatus 1 of the present embodiment. Fig. 3 is a schematic front view of the recording apparatus 1 of the present embodiment. Fig. 4 is a schematic side view of the recording apparatus 1 of the present embodiment. Fig. 5 is a schematic rear view of the recording apparatus 1 of the present embodiment. Fig. 1 to 5 show a state in which a part of the components is removed from the recording apparatus 1 of the present embodiment, and for example, a state in which the sub carriage 5 (see fig. 6 and 7) is removed from the carriage 6.
The recording apparatus 1 of the present embodiment includes a conveying mechanism 3, and the conveying mechanism 3 conveys a recording medium (medium) in a conveying direction a by an adhesive tape 2 (endless belt) that supports the recording medium by a support surface to which an adhesive is adhered. Further, a non-illustrated extracting unit is provided, to which a roll-shaped recording medium can be attached, and which can extract the recording medium to the conveying mechanism 3. Further, the recording mechanism 4 is provided, and the recording mechanism 4 performs recording by reciprocating scanning a carriage 6 provided with a recording head 7 as a discharge portion in a reciprocating direction B intersecting the conveying direction a of the recording medium in a region where the recording medium is conveyed by the conveying mechanism 3. Further, a winding mechanism, not shown, is provided, and the winding mechanism can wind the recording medium on which recording is performed by the recording mechanism 4.
The conveying mechanism 3 of the present embodiment includes: an adhesive tape 2 for carrying and transporting the recording medium drawn out from the drawing section; a driving roller 8 and a driven roller 9, the driving roller 8 and the driven roller 9 moving the adhesive tape 2. The recording medium is attached to and placed on the support surface of the adhesive tape 2.
However, the endless belt as the transport belt is not limited to the adhesive belt. For example, an electrostatic adsorption type endless belt may be used.
The recording apparatus 1 of the present embodiment is provided with the transport mechanism 3 having the above-described configuration, but is not limited to the transport mechanism having the above-described configuration, and may be configured to support and transport the recording medium by a movable support tray or the like, or configured to transport the recording medium by a roller or the like. Further, the recording apparatus may be a so-called tablet type recording apparatus in which a recording medium is fixed to a support portion and recording is performed by moving the recording head 7 with respect to the fixed recording medium.
The recording mechanism 4 includes a carriage motor 30 (see fig. 8), and the carriage motor 30 reciprocates a carriage 6 including a recording head 7 capable of ejecting ink (liquid) in a reciprocating direction B.
The recording apparatus 1 of the present embodiment performs recording by reciprocating scanning the carriage 6 including the recording head 7 during recording, but the conveying mechanism 3 stops conveying the recording medium during recording scanning (during movement of the carriage 6). In other words, at the time of recording, the reciprocating scanning of the carriage 6 and the conveyance of the recording medium are alternately performed. That is, at the time of recording, the transport mechanism 3 intermittently transports the recording medium (intermittently moves the adhesive tape 2) in accordance with the reciprocating scanning of the carriage 6.
Although the recording apparatus 1 of the present embodiment includes the recording head 7 that performs recording while performing reciprocating movement, it may be a recording apparatus including a so-called line head in which a plurality of nozzles for ejecting ink are provided in a direction intersecting the transport direction a.
Here, the "line head" refers to a recording head used in a recording apparatus which is provided so that a region of a nozzle formed in a crossing direction crossing a transport direction a of a recording medium can cover the entire crossing direction of the recording medium and relatively moves the recording head or the recording medium to form an image. Further, the nozzle area in the intersecting direction of the line head may not cover the entire intersecting direction of all the recording media corresponding to the recording apparatus.
Further, a track 10a extending in the reciprocating direction B is formed on a duct 11a constituting the skeleton portion of the recording apparatus 1 of the present embodiment, and a track 10B extending in the reciprocating direction B is formed on a duct 11B constituting the skeleton portion of the recording apparatus 1 of the present embodiment. Further, the movement of the carriage 6 in the reciprocating direction B in the present embodiment is guided by the rails 10a and 10B by receiving bearing portions, not shown, in the rails 10a and 10B.
A blowing portion 12 is provided at a lower position of the duct 11B, and the blowing portion 12 extends in the reciprocating direction B and blows air in a direction opposite to the conveying direction a from a plurality of blowing ports, not shown. A mist recovery unit 13 is provided at a lower position of the duct 11a, and the mist recovery unit 13 extends in the reciprocating direction B and is capable of recovering the ink mist ejected from the recording head 7. Further, the mist recovery unit 13 is provided with a recovery port 16, and the recovery port 16 extends in the reciprocating direction B at a lower position of the duct 11 a.
As shown in fig. 3, a plurality of (three) exhaust fans 14 for generating the blowing force by the blowing unit 12 are provided on the downstream side in the transport direction a of the recording apparatus 1 of the present embodiment. The air blowing unit 12 can blow air from the outside of the recovery unit 13 (at a position downstream in the conveyance direction a) to the recovery port 16 by the blowing force generated by the exhaust fan 14. As shown in fig. 5, a plurality of (three) suction fans 15 as suction portions for generating air flows from the recovery port 16 to the inside of the recovery portion 13 and further from the inside of the recovery portion 13 to the outside of the recording apparatus 1 are provided on the upstream side in the transport direction a of the recording apparatus 1 according to the present embodiment.
Next, a carriage 6 which is a main part of the recording apparatus 1 of the present embodiment and a sub-carriage 5 mounted on the carriage 6 will be described.
Here, fig. 6 is a schematic front view of the carriage 6, and fig. 7 is a schematic side perspective view of the sub carriage 5.
As shown in fig. 6, the carriage 6 of the present embodiment is configured to be able to mount a plurality of sub-carriages 5 and perform reciprocating scanning in the reciprocating direction B.
As shown in fig. 7, the sub carriage 5 includes: a discharge portion housing section 20 in which the recording head 7 is housed; the drive substrate accommodating portion 19 accommodates a drive substrate 40 for driving the recording head 7. The drive substrate housing section 19 and the ejection section housing section 20 are connected by a connection section 38 (connector terminal) on the drive substrate housing section 19 side and a connection section 39 (connector terminal) on the ejection section housing section 20 side. Further, the drive substrate 40 and the connection portion 38 are connected by an FFC (flexible flat cable) 43, and the recording head 7 and the connection portion 39 are connected by an FFC 44.
As shown in fig. 7, fans 21 as first airflow generating portions capable of sending airflow into the drive substrate housing portion 19 are provided on both end portions of the drive substrate housing portion 19 in the conveying direction a so as to face each other. Further, an exhaust port 41 as an exhaust portion for exhausting the synthetic airflow W1 of the airflows generated by the two opposing fans 21 is provided at an end portion (the opposite side of the recording head 7) of the driving substrate accommodating portion 19 in the vertical upward direction C.
On the other hand, a fan 22 as a second airflow generating portion capable of sending an airflow into the ejection portion housing portion 20 is provided at a downstream end portion of the ejection portion housing portion 20 in the conveying direction a. Further, an exhaust port 42 as an exhaust portion for discharging an air flow W2 generated by the fan 22 is provided at an upstream end portion (a position facing the fan 22) in the conveying direction a of the ejection portion accommodating portion 20.
Next, an electrical structure of the recording apparatus 1 of the present embodiment is explained.
Fig. 8 is a block diagram of the recording apparatus 1 of the present embodiment.
The control unit 23 is provided with a CPU24 for controlling the entire recording apparatus 1. The CPU24 is connected to a ROM26 in which various control programs executed by the CPU24 and the like are stored and a RAM27 capable of temporarily storing data, via a system bus 25.
The CPU24 is connected to a head driving unit 28 for driving the recording head 7 via the system bus 25.
In addition. The CPU24 is connected to a motor driving unit 29 for driving the carriage motor 30, the transport motor 31, the drawing motor 32, the winding motor 33, the discharge fan motor 17, the suction fan motor 18, the substrate accommodating unit fan motor 36, and the ejection unit accommodating unit fan motor 37 via the system bus 25.
Here, the carriage motor 30 is a motor for moving the carriage 6 including the recording head 7. The conveyance motor 31 is a motor for driving the drive roller 8. The extracting motor 32 is a driving motor of an extracting unit for feeding the recording medium set in an extracting unit, not shown, to the transport mechanism 3. The winding motor 33 is a drive motor that drives a winding mechanism, not shown, to wind the recording medium on which recording is performed. The fan motor 17 is a motor for driving the fan 14. In addition, the suction fan motor 18 is used for driving the motor of the suction fan 15. The driving substrate accommodating portion fan motor 36 is a motor for driving the fan 21 provided in the driving substrate accommodating portion 19. The ejection-section accommodating-section fan motor 37 is a motor for driving the fan 22 provided in the ejection-section accommodating section 20.
Further, the CPU24 is connected to the input/output unit 34 via the system bus 25, and the input/output unit 34 is connected to a PC35 for transmitting and receiving data such as recording data and signals.
Here, in summary, the recording apparatus 1 of the present embodiment includes: a recording head 7 for ejecting ink; a drive substrate 40 for driving the recording head 7; and a drive substrate accommodating portion 19 for accommodating the drive substrate 40. Further, the present invention includes: a plurality of fans 21 provided in the drive substrate accommodating portion 19 and generating an air flow; and an exhaust port 41 provided in the drive substrate accommodating portion 19 for exhausting a synthesis gas flow W1 of the flows generated by the plurality of fans 21. Therefore, the plurality of fans 21 can efficiently send the air flow to the drive substrate 40, and the heat generated by the drive substrate 40 is transferred, so that the air flow having a temperature increased can be efficiently discharged from the exhaust port 41. Therefore, the recording apparatus 1 of the present embodiment is configured to effectively suppress heat accumulation in the drive substrate housing section 19.
Further, as shown in fig. 7, the drive board housing portion 19 of the present embodiment is formed with the exhaust port 41 for discharging the synthetic gas flow W1, but instead of the exhaust port 41, a suction fan (a fan that generates an air flow from the inside to the outside of the drive board housing portion 19) may be formed as the exhaust portion. With this structure, the discharge efficiency of the syngas flow W1 is further improved.
Further, although the ink is likely to evaporate from the nozzles (not shown) when the temperature of the recording head 7 increases, and the ejection stability may be lowered, as shown in fig. 7, the exhaust port 41 of the present embodiment is provided on the opposite side (the vertically upward direction C side) to the direction (lower side) of the recording head 7 with respect to the drive substrate 40. Therefore, the temperature of the recording head 7 can be prevented from being increased by the synthetic gas flow W1 (the flow heated by the heat of the drive substrate 40) discharged from the exhaust port 41.
As shown in fig. 7, the plurality of fans 21 of the present embodiment provided in the drive substrate accommodating portion 19 are provided at respective opposing positions. Therefore, the synthesis position of the gas flow and the traveling direction of the synthesis gas flow W1 can be easily grasped, the exhaust port 41 can be disposed at an appropriate position, and the synthesis gas flow W1 can be prevented from being accumulated in the drive substrate accommodating unit 19 and from being heated and accumulated in the drive substrate accommodating unit 19.
Here, the plurality of fans 21 of the present embodiment provided in the drive substrate accommodating portion 19 each use the same fan. That is, fans having the same air volume are used for the plurality of fans 21. Therefore, the synthesis position of the gas flow and the traveling direction of the synthesis gas flow W1 (in the present embodiment, the central portion of the drive substrate accommodating section 19 in the transport direction a) can be grasped more easily, and the exhaust port 41 can be disposed at a more appropriate position, whereby the synthesis gas flow W1 can be particularly effectively prevented from being accumulated in the drive substrate accommodating section 19 and heat can be effectively prevented from accumulating in the drive substrate accommodating section 19.
Note that "equal" does not mean the same in a strict sense, but means that the air volumes of the plurality of fans 21 are slightly different due to, for example, a variation in design.
As shown in fig. 6 and 7, the sub-carriage 5 of the present embodiment accommodates the recording head 7 and the drive board 40 separately as a separate body. In other words, the sub-carriage 5 of the present embodiment includes the ejection portion accommodating portion 20 for accommodating the recording head 7 separately from the drive substrate accommodating portion 19. In this manner, the drive substrate 40 and the recording head 7 are accommodated in different accommodating portions, thereby effectively suppressing heat generated by the drive substrate 40 from being transmitted to the recording head 7.
However, the present invention naturally includes a configuration in which the recording head 7 and the drive substrate 40 are accommodated in one accommodation portion (a configuration in which a drive substrate accommodation portion accommodating both the recording head 7 and the drive substrate 40 is provided).
Further, the fan 22 that generates the air flow W2 is provided in the ejection portion housing portion 20, and heat accumulation in the ejection portion housing portion 20 can be suppressed.
Further, as shown in fig. 7, the discharge portion housing portion 20 of the present embodiment is formed with the exhaust port 42 at a position facing the fan 22, but a suction fan (a fan that generates an air flow from the inside to the outside of the discharge portion housing portion 20) may be formed as the exhaust portion instead of the exhaust port 42. With this configuration, the discharge efficiency of the airflow W2 is further improved.
In addition, as shown in fig. 7, the drive substrate 40 of the present embodiment is disposed along the direction of the recording head 7 relative to the drive substrate 40 (the direction in the vertically upward direction C). In other words, the drive substrate 40 of the present embodiment is disposed in a configuration not facing the recording head 7. Therefore, the heat generated by the drive substrate 40 is effectively suppressed from being transmitted to the recording head 7.
The present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention.
