Next, the operation of the liquid discharge device 11 configured as described above will be described.
When the liquid storage container 24 connected to the housing unit 14 is pivoted downward by the load applied to the projection 32 b protruding from the housing 14 or the weight of the projection 32 b, the liquid storage container 24 with respect to the connection 31 of the liquid outlet 32 c The connection may not be maintained properly.
In that respect, since the liquid discharge device 11 of the present embodiment includes the support unit 26 that supports the projection 32 b of the liquid storage container 24 from the lower side in the vertical direction outside the housing 14, the rotation of the liquid storage container 24 is suppressed. Be done. In addition, since the load applied to the self weight of the protrusion 32b and the protrusion 32b is supported by both the housing 14 and the housing support 13 via the support unit 26, the load can be dispersed.
In particular, there is a risk that a large load may be applied to the end of the liquid container 24 or the displacement due to rotation may increase, but the load applied to the end of the liquid container 24 may be through the end support portion 43. It is transmitted to the case support 13. Therefore, even when a large load or impact is applied to the housing unit 14, the vibration is unlikely to be applied to the liquid discharge unit 30 in the housing unit 14, so that the deterioration of the printing performance is suppressed. Further, by supporting the load applied to the tip end side of the liquid storage container 24 by the case support portion 13 located at a lower position than the case portion 14, the center of gravity balance of the liquid discharge device 11 can be maintained.
In the liquid storage container 24 of the present embodiment, the protruding direction is the longitudinal direction, and the protrusion 32 b protruding from the housing 14 is more liquid than the base end 32 a housed in the housing 14. Because the storage capacity is large, the front end side is easily inclined downward. In addition, when the liquid storage container 24 becomes large, the components of the liquid receiving portion 39 and the support unit 26 provided accompanying the liquid storage container 24 also become large, so that manufacturing errors and mounting errors become large, and the support unit 26 and the liquid storage The position of the container 24 may shift.
In that respect, in the present embodiment, among the constituent elements of the support unit 26, the position of the container support portion 62 in contact with the protrusion portion 32b of the liquid storage container 24 can be adjusted. And the influence of the positional offset of the side support part 61 can be suppressed.
Further, in the present embodiment, among the components constituting the support unit 26, the positions of the first adjustment member 64 and the second adjustment member 66 disposed at the position sandwiching the liquid receiving portion 39 can be adjusted. Thereby, even when an error occurs in the mounting position of the liquid receiving portion 39 or the load transfer portion 65, the influence of the positional deviation is suppressed, and the load applied to the projecting portion 32b from the load transfer portion 65 to the case support portion It can be reliably transmitted to 13.
Further, since the fixing of each component capable of performing the position adjustment is performed with a screw, the position can be easily adjusted with a driver without using a special tool.
For example, as shown in FIG. 5, the support position adjustment screw 74 for adjusting the position of the container support 62 and the upper adjustment screw 72 for adjusting the position of the first adjustment member 64 use the space in front of the liquid storage unit 25. Thus, the driver can perform a turning operation from the front side. In FIG. 5, in order to clearly show the configuration of the first adjustment member 64 etc., the load transfer part 65, the second adjustment member 66, the protective plate 38, the liquid receiving part 39 and the liquid storage member 40 are omitted. There is.
In the present embodiment, in the load transfer unit 65, the area of the surface receiving the load through the container support unit 62 (the area in contact with the load transfer unit 65 of the second adjustment member 66) projects the protrusion 32b on the horizontal surface. Smaller than the projected area. Also, the container support 62 extending in the moving direction X contacts the plurality of protrusions 32 b, and the load received by the plurality of protrusions 32 b is via the first adjustment member 64 and the second adjustment member 66 extending in the vertical direction. Is transmitted to the load transfer unit 65. Therefore, the installation space of the end support portion 43 may be smaller than the space required when arranging a box-like support member supporting the entire bottom surface of the protrusion 32 b.
Furthermore, the load transfer unit 65 is connected to the housing support 13 in a mode capable of transferring the load received by the protrusion 32 b, but the load transfer unit 65 is supported in a cantilever manner by the housing support 13. By doing this, it is possible to further reduce the installation space of the end supporting portion 43 below the projection 32 b in the vertical direction. In the present embodiment, since the arm member 19 and the holder 21 are disposed vertically below the projection 32 b, the miniaturization of the support unit 26 similarly disposed below the liquid receiving portion 39 is particularly advantageous. .
(1) When a load is applied to the projecting portion 32 b of the liquid storage container 24 connected to the connection portion 31, the load transmitting portion 65 transmits the load to the housing support portion 13, so that the inside of the housing portion 14 is The projection 32b can be supported so as not to be displaced while suppressing the influence on the components of the projection 32b. Therefore, the influence by applying a load to the part which protruded from the housing part 14 of the liquid storage container 24 connected to the housing part 14 can be suppressed.
(2) By providing the container support 62 in contact with the protrusion 32 b of the liquid storage container 24 separately from the load transfer unit 65, the container support 62 is formed according to the shape of the protrusion 32 b, etc. The load transfer portion 65 can be formed in a shape that can efficiently transfer the load to the housing support portion 13.
(3) Even when the plurality of liquid storage containers 24 are connected, the container supporting portion 62 in contact with the plurality of protruding portions 32 b can transmit the load received by the plurality of protruding portions 32 b to the load transfer portion 65 it can.
(4) The load transfer unit 65 can be miniaturized because the area of the load transfer unit 65 that receives the load via the container support 62 is smaller than the projected area of the projection 32 b projected on the horizontal surface. .
(5) By arranging the load transfer unit 65 in the vertical direction below the protrusion 32 b of the liquid storage container 24, a load is applied to the protrusion 32 b such that the protruding end is rotated downward in the vertical direction In this case, the protrusion 32b can be supported more stably.
(6) Even when an error occurs in the position of the load transfer unit 65, the load can be reliably transmitted by adjusting the relative position of the second adjustment member 66 with respect to the load transfer unit 65.
The end support 43 may be formed of one member. In this case, the end support portion 43 functions as a load transfer portion. Further, the end supporting portion 43 can also be configured by a plurality of members different from the above embodiment.
The liquid discharge device 11 may not include any or all of the rear end support portion 42, the protection plate 38, the liquid receiving portion 39, and the liquid storage member 40.
When the liquid discharger 11 does not include the liquid receiving portion 39, the second adjusting member 66 is not provided, and the first adjusting member 64 is extended downward in the vertical direction so as to be directly connected to the load transmitting portion 65. May be Also in this case, by moving the first adjustment member 64 functioning as the relay member in the vertical direction, the influence of the positional deviation of the load transfer unit 65 can be suppressed.
The liquid discharger 11 does not include the second adjusting member 66, and the liquid receiving portion 39 is provided with a through hole, and the first adjusting member 64 is extended downward in the vertical direction so as to penetrate the through hole. You may make it connect to the transmission part 65 directly. Also in this case, by moving the first adjustment member 64 functioning as the relay member in the vertical direction, the influence of the positional deviation of the load transfer unit 65 can be suppressed. However, in this case, there is a risk that the liquid received by the liquid receiving portion 39 may leak from the through hole, so the first adjusting member 64 and the second adjusting member 66 sandwich the liquid receiving portion 39 as in the above embodiment. It is preferable to set it as an aspect.
The first adjustment member 64 may be connected to each of the fixing plate portions 68 without the connecting member 63. However, in this case, since the second adjustment member 66 and the first adjustment member 64 are not aligned in the vertical direction, the liquid receiving portion is more than when the second adjustment member 66 and the first adjustment member 64 are aligned in the vertical direction. It is preferable to increase the strength of 39.
The liquid storage container 24 may be configured without the inlet 34.
The number of liquid storage containers 24 can be arbitrarily changed. Alternatively, the liquid storage container 24 provided with the injection port 34 and the liquid storage container 24 not provided with the injection port 34 may constitute the liquid storage unit 25. For example, in the case of monochrome printing, if the inlet 34 is provided in the liquid container 24 corresponding to black ink, a large amount of monochrome printing can be performed continuously. In this case, the liquid storage container 24 corresponding to the color ink may not include the protrusion 32 b and the injection port 34, and the entire liquid storage container 24 may be stored in the housing 14.
The liquid storage container 24 may not necessarily store the liquid discharged by the liquid discharge unit 30. For example, the liquid storage container 24 may be a cleaning liquid for cleaning the liquid discharge unit 30 or the like, a moisturizing liquid for suppressing the drying of the liquid discharge unit 30, or a waste liquid from the liquid discharge unit 30 for maintenance. It may be one containing the discharged liquid or the like.
The liquid storage container 24 may be connected to the connection portion 31 in a state in which the liquid is stored, or may be connected to the connection portion 31 in an empty state in which the liquid is not stored. May be injected.
· The downstream end of an ink tube whose upstream end is connected to an ink tank or the like disposed outside the housing unit 14 is connected to the injection port 34 of the liquid storage container 24 so that the ink is simultaneously injected and printed. It may be possible to
The liquid discharge device 11 may be changed to a so-called line head type liquid discharge device that does not include the carriage 29 but includes the long fixed liquid discharge unit 30 corresponding to the entire width of the medium S. In this case, the liquid discharge unit 30 may arrange the recording range over the entire width of the medium S by arranging in parallel a plurality of unit head units in which the nozzles for discharging the liquid as droplets are formed. The recording range may extend over the entire width of the medium S by arranging a large number of nozzles on one long head over the entire width of the medium S.
The liquid ejected or jetted from the liquid ejection unit 30 is not limited to the ink, and may be, for example, a liquid in which particles of a functional material are dispersed or mixed in the liquid. For example, recording is performed by discharging a liquid material containing materials such as electrode materials and coloring materials (pixel materials) used for manufacturing liquid crystal displays, EL (electroluminescence) displays, and surface emitting displays in the form of dispersion or dissolution. It may be configured.
