Description

The present invention relates to an inkjet recording device.

Techniques related to inkjet recording devices have been proposed. For example, Patent Document 1 discloses a device that discharges liquid. The device that ejects liquid is an inkjet printer. In an inkjet printer, a carriage is moved and scanned in a main scanning direction. A suction fan is installed at the top inside the device main body. The suction fan generates airflow in the following directions: The above-mentioned direction is the direction in which the air inside the device main body is discharged to the outside. A mist suction duct is connected to the upstream side of the suction fan via a filter, an exhaust duct, a mist suction tube, and a flow path connecting member. The liquid mist is collected by the filter by the airflow through the mist suction duct, the flow path connecting member, the mist suction tube, and the exhaust duct. Liquid mist is generated by liquid ejection from the head. The mist suction ducts are provided on both sides of the carriage in the main scanning direction. The mist suction duct is provided near the nozzle of the head. In this device, the opening surface of the mist suction duct and the nozzle surface are preferably at the same height.

The capture body 75 has a convex curved surface or bent surface on the first side in the first direction and on the second side in the first direction. In the inkjet recording apparatus 10, the capture body 75 has a curved surface that is convex on the first side in the first direction on the second side in the first direction (see FIG. 3). In the capture body 75, when the surface on the second side in the first direction is a curved surface convex to the first side in the first direction, the surface on the second side in the first direction can also be a triangular curved surface. good. In this case, it is preferable that the above-mentioned bent surface has an equilateral triangular shape or an isosceles triangular shape (see FIG. 7 described later). The capture body 75 is formed of a sheet-like member. For example, the capture body 75 may be a metal mesh (see FIG. 4). Preferably, the capture body 75 is made of stainless steel mesh. However, the shape and material of the capture body 75 are appropriately determined in consideration of various conditions. For example, when determining the material of the capture body 75, the components of the ink are taken into consideration. The grid showing the capture body 75 in FIG. 4 indicates that the capture body 75 is a mesh. In the inkjet recording device 10, since the capture body 75 is sheet-shaped, the first side surface of the capture body 75 in the first direction is a surface along the second side surface of the capture body 75 in the first direction. (See Figure 3).

The capture body 75 is provided in the storage chamber 52 (see FIGS. 3 and 4). The capture body 75 is provided in the first accommodation chamber 53 on the first side of the suction port 51 in the first direction. In the capture body 75, the first end 76 on the fifth side in the third direction is accommodated in the first receiving chamber 68, and the second end 77 on the sixth side in the third direction is accommodated in the second receiving chamber 69. (See Figure 3). The capture body 75 spans between the first region R1 of the first side wall 55 and the second region R2 of the first side wall 55 in the storage chamber 52. The capture body 75 captures ink mist contained in the air sucked in from the suction port 51. The air sucked in from the suction port 51 flows in the first direction in the first direction toward the exhaust port 86, which will be described later, inside the storage chamber 52. At that time, the air passes through the trap 75. The trap 75 traps the ink mist contained in this air. After the ink mist adheres to the trap 75 , it flows along the surface of the trap 75 to either one of the first receiving chamber 68 and the second receiving chamber 69 . The surface of the capture body 75 includes a surface on the first side of the capture body 75 in the first direction, and a surface on the second side of the capture body 75 in the first direction.

The guide 85 has an exhaust port 86 . The exhaust port 86 is connected to a suction device 99 via an exhaust duct 98 (see FIG. 1). The suction device 99 sucks air sucked in from the suction port 51. In other words, the recovery device 40 sucks air from the suction port 51 as the suction device 99 operates. 1, 3, and 4, the exhaust duct 98 shows a portion on the exhaust port 86 side.

In the collectors 41, 42, 43, 44, and 45, the guide 85 is provided on the first side of the conveying surface 21 in the first direction. Furthermore, in the recovery device 41, the guide 85 is provided in line with the inkjet head 30Y on the fifth side in the third direction of the inkjet head 30Y. In the recovery device 42, the guide 85 is provided between the inkjet heads 30Y and 30M in parallel with the inkjet heads 30Y and 30M in the third direction. In the recovery device 43, the guide 85 is provided between the inkjet heads 30M and 30C in parallel with the inkjet heads 30M and 30C in the third direction. In the recovery device 44, the guide 85 is provided between the inkjet heads 30C and 30K in parallel with the inkjet heads 30C and 30K in the third direction. In the recovery device 45, the guide 85 is provided in line with the inkjet head 30K on the sixth side in the third direction of the inkjet head 30K. The guides 85 in all the collectors 40 of the collectors 41, 42, 43, 44, and 45 are fixedly arranged at the positions described above.

The container 50 is suspended on the guide 85 on the second side in the first direction (see FIG. 3). The container 50 includes first engaging portions 70 and 71. The first engaging portion 70 is provided on the first side of the container 50 in the first direction and on the fifth side in the third direction. The first engaging portion 71 is provided on the first side of the container 50 in the first direction and on the sixth side in the third direction. The guide 85 includes second engaging portions 87 and 88. The second engaging portion 87 is provided on the second side of the guide 85 in the first direction and on the fifth side in the third direction. The second engaging portion 88 is provided on the second side of the container 50 in the first direction and on the sixth side in the third direction. The first engaging portions 70, 71 and the second engaging portions 87, 88 have a flat plate shape along the second direction and the third direction. The first engaging portion 70 overlaps the second engaging portion 87 on the fifth side in the third direction in the next first state in the first direction. The first state is a state in which the first engaging portion 70 is on the first side in the first direction, and the second engaging portion 87 is on the second side in the second direction. The first engaging portion 71 overlaps the second engaging portion 88 on the sixth side in the third direction in the next second state in the first direction. The second state is a state in which the first engaging portion 71 is on the first side in the first direction, and the second engaging portion 88 is on the second side in the second direction.

In the recovery device 40, as described above, the first engaging parts 70, 71 overlap with the second engaging parts 87, 88, so that the first engaging parts 70, 71 are caught on the second engaging parts 87, 88. , the container 50 is suspended on the second side of the guide 85 in the first direction. In the recovery device 40, the first engaging portion 70 is pulled by pulling the container 50 from the third side to the fourth side in the second direction or pushing the container 50 from the fourth side to the third side in the second direction. , 71 slide on the second engaging portions 87, 88 in the direction of the force acting on the container 50. Along with this, the container 50 moves from the third side to the fourth side in the second direction, or moves from the fourth side to the third side in the second direction. In this case, the guide 85 guides the movement of the container 50 in the second direction from the third side to the fourth side and the movement of the container 50 in the second direction from the fourth side to the third side.

When recording a pattern on the recording medium 15, the container 50 in the collectors 41, 42, 43, 44, and 45 is in the following third state (see FIG. 1). The third state is a state in which the container 50 is placed at the moving end on the third side in the second direction. When the container 50 is in the third state, the suction port 51 is arranged on the first side of the transport surface 21 in the first direction and faces the transport surface 21 (recording medium 15). For example, when maintenance of the recovery device 40 is required, the operator pulls out the container 50 in the third state of the recovery device 40 to be maintained toward the fourth side in the second direction. Accordingly, the container 50 in the third state moves from the third side in the second direction to the fourth side and enters the fourth state. The fourth state is a state in which the container 50 is placed at the moving end on the fourth side in the second direction. The moving end on the fourth side in the second direction in the fourth state is a position where the container 50 is on the fourth side in the second direction from the inkjet heads 30Y, 30M, 30C, and 30K. That is, the guide 85 guides the container 50 to a position on the fourth side in the second direction from the inkjet heads 30Y, 30M, 30C, and 30K lined up in the third direction. The moving end on the fourth side in the second direction in the fourth state may be a position where the entire capture body 75 is on the fourth side in the second direction from the inkjet heads 30Y, 30M, 30C, and 30K. In FIG. 1, the container 50 in the third state is shown by a solid line, and the container 50 in the fourth state is shown by a two-dot chain line.

The cover 90 is provided in the storage chamber 52 ( see FIGS. 3 and 4). Furthermore, a cover 90 is provided on the first plate 62 in the second receiving chamber 54 . Therefore, the cover 90 is provided in the storage chamber 52 on the first side of the capture body 75 in the first direction. The cover 90 covers the first side of the storage chamber 52 in the first direction. In other words, the cover 90 separates the second side surface of the guide 85 in the first direction (the inner surface of the guide 85 ) from the storage chamber 52 . The cover 90 preferably separates at least the following areas of the inner surface of the guide 85 from the storage chamber 52: The above-mentioned area is the area of the inner surface of the guide 85 that will be exposed when the container 50 is placed in the above-mentioned fourth state. The cover 90 is provided with a through hole 91 that penetrates the side wall in the first direction at a position next to the side wall on the first side in the first direction. The above-mentioned position is a position where the cover 90 overlaps the exhaust port 86 in the first direction when it is installed in the storage chamber 52 (see "center line L" in FIG. 4). In other words, the above-mentioned position is a position that coincides with the exhaust port 86 in the second direction and the third direction in the above-mentioned state.

<Effects of embodiment>
According to the embodiment, the following effects can be obtained.

(1) In the inkjet recording apparatus 10, the collectors 41, 42, 43, 44, and 45 are arranged alternately with the inkjet heads 30Y, 30M, 30C, and 30K in the third direction (see FIG. 1). The collector 40 collects ink mist. The collector 40 includes a container 50, a capture body 75, and a guide 85 (see FIGS. 3 and 4). The container 50 has a storage chamber 52 inside. The trap 75 traps ink mist. The guide 85 guides the movement of the container 50 from the third side to the fourth side in the second direction and the movement of the container 50 from the fourth side to the third side in the second direction (see FIG. 1). ). The container 50 has a suction port 51 on the second side in the first direction (see FIGS. 3, 4, and 6). The suction port 51 communicates with the storage chamber 52 . The capture body 75 is provided in the storage chamber 52 on the first side of the suction port 51 in the first direction (see FIGS. 3 and 4). The guide 85 guides the container 50 to a position on the fourth side in the second direction from the inkjet heads 30Y, 30M, 30C, and 30K (see FIG. 1).

Therefore, the ink mist can be captured by the capture body 75. The container 50 can be pulled out from the inkjet heads 30Y, 30M, 30C, and 30K to a position on the fourth side in the second direction. When the inkjet recording apparatus 10 is in a recording operation state, the collectors 41, 42, 43, 44, and 45 collect ink mist at positions lined up with the inkjet heads 30Y, 30M, 30C, and 30K in the third direction. On the other hand, when some or all of the collectors 41, 42, 43, 44, and 45 require maintenance, the collectors 40 that require maintenance have their containers 50 moved in the second direction. pulled out to the fourth side. The maintainability of the recovery device 40 in the inkjet recording apparatus 10 can be improved.

(2) The recovery device 40 includes a cover 90 (see FIGS. 3 and 4). The cover 90 covers the first side of the storage chamber 52 (second storage chamber 54) in the first direction. The cover 90 is provided in the storage chamber 52 on the first side of the capture body 75 in the first direction. The guide 85 has an exhaust port 86 . Therefore, the housing chamber 52 and the guide 85 can be separated by the cover 90. The air sucked into the recovery device 40 and passed through the capture body 75 can be exhausted from the first side in the first direction. When air flows out from the exhaust port 86 to the exhaust duct 98, ink mist contained in this air can be prevented from adhering to the guide 85. For example, the following event can be prevented in a state where the container 50 is pulled out to the fourth side in the third direction. The aforementioned event is that ink falls from the guide 85 and contaminates one or both of the recording medium 15 and the transport device 20 (transport surface 21). Regardless of the movement of the container 50 in the second direction, the exhaust port 86 can be arranged at a constant position. The configuration of the exhaust duct 98 can be simplified. For example, there is no need for the exhaust duct 98 to have a telescopic function.

(3) The storage chamber 52 includes a first storage chamber 53 and a second storage chamber 54 (see FIGS. 3 and 4). The container 50 includes a partition wall 60. The partition wall 60 partitions the storage chamber 52 into a first storage chamber 53 and a second storage chamber 54 . The partition wall 60 has a connection port 61 . The connection port 61 connects the first storage chamber 53 and the second storage chamber 54. The capture body 75 is provided in the first accommodation chamber 53 on the first side of the suction port 51 in the first direction. A cover 90 is provided on the partition wall 60 in the second storage chamber 54 . Therefore, the air that has passed through the capture body 75 can be made to flow into the second storage chamber 54 via the connection port 61.

(4) The partition wall 60 includes a first plate 62 and a second plate 64 (see FIGS. 3 to 5). The second plate 64 is stacked with the first plate 62 in the first direction. The second plate 64 is provided to be movable relative to the first plate 62 in a second direction. The first plate 62 has a first opening 63. The first opening 63 penetrates the first plate 62 in the first direction. The second plate 64 has a second opening 65. The second opening 65 penetrates the second plate 64 in the first direction. The second opening 65 is connected to the first opening 63 in the first direction in a state where the second plate 64 and the first plate 62 are stacked. The first opening 63 and the second opening 65 become the connection port 61. In the connection port 61, when the position of the second plate 64 in the second direction with respect to the first plate 62 is the middle position in FIG. 5, the opening area of the connection port 61 is in a fully open state. On the other hand, when the position of the second plate 64 in the second direction with respect to the first plate 62 is the position shown in the lower part of FIG. 5, the opening area of the connection port 61 is in a half-open state. Therefore, the opening area of the connection port 61 can be changed. The flow rate of air flowing into the second storage chamber 54 can be adjusted.

(5) The container 50 includes a first side wall 55, a first suction wall 66, and a second suction wall 67 (see FIGS. 3 and 6). The first side wall 55 is provided on the second side of the container 50 in the first direction. The first side wall 55 has a suction port 51 . The first suction wall 66 is continuous with the sixth side end in the third direction of the first region R1 of the first side wall 55, and its tip faces toward the accommodation chamber 52. The second suction wall 67 is continuous with the fifth side end in the third direction of the second region R2 of the first side wall 55, and its tip faces toward the storage chamber 52. The capture body 75 spans between the first region R1 of the first side wall 55 and the second region R2 of the first side wall 55 in the storage chamber 52 (first storage chamber 53) (see FIG. 3). Therefore, the capture body 75 can be provided in the storage chamber 52 in a state facing the suction port 51. The air sucked into the recovery device 40 can be passed through the capture body 75 .

(6) The capture body 75 has a convex curved surface or bent surface on the first side in the first direction on the second side in the first direction (see FIG. 4 and FIG. 7 described later). Therefore, the surface area of the capture body 75 can be increased. Accordingly, the area where the ink mist is captured by the capture body 75 can be expanded.

<Modified example>
Embodiments (see FIGS. 1-6) may also be as follows. Some of the configurations of the modified examples shown below can also be employed in combination as appropriate. Below, points different from the above will be explained, and explanations of similar points will be omitted as appropriate.

(1) The first receiving chamber 68 and the second receiving chamber 69 may have a shape that is inclined toward one or both of the third side and the fourth side in the second direction. For example, the first receiving chamber 68 and the second receiving chamber 69 may have the following configuration. In the above embodiment, the third side end of the first receiving chamber 68 in the second direction is the first side in the first direction, and the third side end of the first receiving chamber 68 is inclined toward the second side in the first direction toward the fourth side in the second direction. It is a mode. Furthermore, in the above embodiment, the third side end of the second receiving chamber 69 in the second direction is the first side in the first direction, and the third side end in the second direction is the second side in the first direction. It is in an inclined manner. In this case, in the first region R1 of the first side wall 55, the first drain may be provided on the fourth side in the second direction. In the second region R2 of the first side wall 55, a second drain may be provided on the fourth side in the second direction. Waste liquid in the first receiving chamber 68 can be drained from the first receiving chamber 68 via the first drain. The waste liquid in the second receiving chamber 69 can be discharged from the second receiving chamber 69 via the second drain. By setting the first receiving chamber 68 and the second receiving chamber 69 in the above-described manner, the following phenomenon does not occur. The aforementioned event is that when the container 50 is moved from one of the third and fourth sides in the second direction to the other, the first drain and the second drain pass over the conveying surface 21. Contamination of one or both of the recording medium 15 and the transport device 20 (transport surface 21) can be prevented.

(2) In the recovery device 40, the capture body 75 is provided in the storage chamber 52 (first storage chamber 53) in the following state. In the above-mentioned state, the first end 76 of the capture body 75 is accommodated in the first receiving chamber 68. Furthermore, the above-mentioned state is a state in which the second end portion 77 of the capture body 75 is accommodated in the second receiving chamber 69. The capture body 75 may be provided in the storage chamber 52 in the manner shown in FIG. In FIG. 7, in order to clarify the correspondence with the recovery device 40 of FIGS. 2 to 6, the reference numerals for each part are the same as above.

The second holding portion 80 may be provided with a second piece 81 at the fifth side end in the second direction. The second piece 81 protrudes toward the first side in the first direction. In the embodiment, the first piece 79 and the second piece 81 are convex pieces along the first direction. Therefore, the tip of the first piece 79 and the tip of the second piece 81 face the first side in the first direction. With the first holding part 78 and the second holding part 80 holding the captured body 75, the first piece 79 prevents the first end 76 of the captured body 75 from falling off, and the second piece 81 prevents the captured body 75 from falling off. This prevents the second end 77 of 75 from falling off.

In this case, the next interval W4 is preferably 1 mm or more. The interval W4 is the interval between the second suction wall 67 and the second piece 81 in the second direction. By setting the distances W3 and W4 to 1 mm or more, the following phenomenon can be prevented. The above-mentioned phenomenon is such that when the waste liquid that has exceeded the first piece 79 flows out into the first receiving chamber 68, this waste liquid flows from the suction port 51 along the sixth side surface of the first suction wall 66 in the third direction. It is leakage to the second side in the first direction. Furthermore, the above phenomenon is such that when the waste liquid that has exceeded the second piece 81 flows out into the second receiving chamber 69, this waste liquid flows through the suction port along the fifth side surface of the second suction wall 67 in the third direction. 51 to the second side in the first direction.

When the second piece 81 is provided in the second holding part 80, the second piece 81 has a shape in which the tip position is the same position in the first direction as the tip of the second suction wall 67, or the tip position is in the second suction wall 67. It is preferable that the shape is on the second side in the first direction from the tip of the wall 67. The area of the first end 76 of the capture body 75 covered by the first piece 79 can be narrowed. The range of the second end 77 of the capture body 75 covered by the second piece 81 can be narrowed. It is possible to widen the range of the capture body 75 that is exposed to the air sucked in from the suction port 51.

(3) In the container 50, the first corner C1 and the second corner C2 are formed at right angles (see FIG. 3). The first corner C1 is a portion where the first region R1 of the first side wall 55 and the first suction wall 66 intersect. The first corner C1 forms the fifth side of the suction port 51 in the third direction. The second corner C2 is a portion where the second region R2 of the first side wall 55 and the second suction wall 67 intersect. The second corner C2 forms the sixth side of the suction port 51 in the third direction. In the container, the first corner C1 and the second corner C2 may have an R shape. The shapes of the first corner C1 and the second corner C2 are appropriately determined in consideration of various conditions.

(4) In the recovery device 40, the container 50 includes first engaging portions 70 and 71, and the guide 85 includes second engaging portions 87 and 88. (See Figure 3). The first engaging portions 70, 71 and the second engaging portions 87, 88 have a flat plate shape.

(7) The inkjet recording apparatus was an inkjet recording apparatus 10 including line-type inkjet heads 30Y, 30M, 30C, and 30K (see FIG. 1). As an inkjet recording apparatus, a different type of apparatus from the inkjet recording apparatus 10 has been put into practical use. In this description, this different type of inkjet recording device will be referred to as a "serial type." The configuration in which the recovery device 40 (41, 42, 43, 44, 45) is provided side by side with the inkjet heads 30Y, 30M, 30C, and 30K can also be adopted in a serial type inkjet recording device, similar to the inkjet recording device 10.

The fifth side in the third direction is one side of the third side and the fourth side in the second direction of the embodiment, and the sixth side in the third direction is the third side and the fourth side in the second direction of the embodiment. Become the other side of the side.

In the serial type inkjet recording apparatus, pattern recording is performed while reciprocating the inkjet heads 30Y, 30M, 30C, and 30K in the third direction. The conveyor 20 moves the inkjet heads 30Y, 30M, 30C, and 30K from the fifth side to the sixth side in the third direction, and moves the inkjet heads 30Y, 30M, 30C, and 30K from the sixth side to the sixth side in the third direction. The recording medium 15 is transported in the transport direction corresponding to the movement toward the fifth side. The conveyance direction is along the second direction. That is, the conveyance of the recording medium 15 by the conveyance machine 20 is performed intermittently at the timing when the inkjet heads 30Y, 30M, 30C, and 30K reach the movement end on the fifth side or the sixth side in the third direction.

For example, the container 50 may be moved in the second direction by moving the inkjet heads 30Y, 30M, 30C, and 30K to the fifth or sixth moving end in the third direction. The moving end of the inkjet head 30Y, 30M, 30C, 30K on the fifth side or the sixth side in the third direction is It is best to position it on the side. That is, in the serial type inkjet recording apparatus, it is preferable that the inkjet heads 30Y, 30M, 30C, and 30K are not on the conveying surface 21. A serial type inkjet recording device is a well-known device that has already been put into practical use. Therefore, other explanations regarding this will be omitted.
