The present application is based on, and claims priority from JP Application Serial Number 2019-197126, filed Oct. 30, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a printing system.
Ink has been replenished by using a consumable item such as an ink cartridge or an ink bottle in the related art. For example, as described in International Publication No. WO 2003/082582, a technique is known in which in replacement of the ink cartridge, color information of the ink cartridge or the like is recognized by using a radio tag of the ink cartridge to move a carriage according to the information and position the ink cartridge whose replacement is required to a replacement position. Further, as described in JP-A-2017-222152, a technique is known in which an ink bottle having an uneven portion and corresponding to an ink inlet port of a printer can be properly coupled by fitting the ink bottle to an uneven portion of an ink tank using the ink bottle.
However, when a container such as an ink cartridge or an ink bottle, which is a consumable item, has a radio tag, an IC chip, or the like, plastics and metals coexist, resulting in large burden on environment when discarded. When a plastic container with unevenness is discarded, the disposal amount increases and burden on environment increases. Therefore, a printing system using an environment-friendly consumable item is desired.
According to an aspect of the present disclosure, there is provided a printing system. The printing system includes a liquid supply container that stores a liquid; a printing device that receives a liquid supplied from the liquid supply container and performs printing; an imaging device that acquires image information including at least a part of the liquid supply container; an acquisition section that acquires reference information; a determination section that collates the image information with the reference information and determines whether or not the liquid is allowed to be supplied according to a collation result; and a control section that controls the printing device according to the determination.
A plurality of liquid containers 113 are provided. In the present embodiment, five liquid containers 113 are provided. Three of the five liquid containers 113 store cyan ink, magenta ink, and yellow ink, and the other two liquid containers 113 store black ink. When the printing device 100 is in an initial state or a liquid in the liquid container 113 is consumed, the liquid container 113 is replenished with the liquid using the corresponding liquid supply container 200. Five types of liquid supply containers 200 corresponding to the five liquid containers 113 are prepared, for example.
The printing device 100 includes a control device 400, an imaging device 300, a carriage 110, a lock mechanism 112, a notification section 120, and a waste liquid tank 117. As illustrated in
As illustrated in
First Information
Information regarding an outer appearance of the liquid supply container 200
Second Information
Color information of the liquid supply container 200 regarding a color of a stored ink, such as a film or label having a portion printed in the color of the stored ink, a film or label on which character information representing the color is printed, or at least a part of the liquid supply container which is dyed in the color of the stored ink, and the like
Third Information
Character information of the liquid supply container 200, such as a product number of the liquid supply container 200
Fourth Information
Code information of the liquid supply container 200, such as a QR code (registered trademark) including information regarding the liquid supply container 200
Fifth Information
Information of the liquid supply container 200 regarding a member reflecting infrared rays
The five types of liquid supply containers 200 corresponding to the five liquid containers 113 are configured to be identifiable by at least one of the first to fifth information. For example, when the liquid supply container 200 is configured to be identifiable by the first information, the five types of liquid supply containers 200 have different outer appearances. For example, when the liquid supply container 200 is configured to be identifiable by the second information, there is color information representing a color of the ink stored in the liquid supply container 200 on an outer surface. For example, when the liquid supply container 200 is configured to be identifiable by the third information, there is character information corresponding to each type of the liquid supply container 200 on an outer surface. For example, when the liquid supply container 200 is configured to be identifiable by the fourth information, there is code information corresponding to each type of the liquid supply container 200 on an outer surface. For example, when the liquid supply container 200 is configured to be identifiable by the fifth information, there is information regarding a member reflecting infrared rays having different sizes or shapes according to each type of the liquid supply container 200.
Image information can be acquired by appropriately combining the first to five information or other information. The image information can be acquired from an image captured by the imaging device 300 using a known image analysis technique.
The acquisition section 10 acquires reference information stored in the storage section 140. The reference information is information using when the determination section 20 performs determination as a reference, for example, reference image information. The reference information may be stored in a device outside the printing device 100. The determination section 20 collates the image information acquired by the imaging device 300 with the reference information acquired by the acquisition section 10, and determines whether or not the liquid is supplied from the liquid supply container 200 according to the collation result. The determination section 20 performs collation using a known technique such as pattern matching, for example. The control section 30 controls the printing device 100 according to the determination of the determination section 20. For example, the control section 30 controls various operations of the printing device 100 when the liquid is filled from the liquid supply container 200 to the liquid container 113 according to the determination of the determination section 20. The print execution section 40 performs control for printing. Details of the determination contents of the determination section 20 will be described below.
As illustrated in
The cover member 111 is provided on the corresponding liquid container 113. The cover member 111 is a lever capable of switching the cover member 111 between two states of a closed state where the liquid fill port 114 of the liquid container 113 is covered and an open state where the liquid fill port 114 is exposed. In the cover member 111, the closed state and the open state can be switched by allowing a user to rotate an operation section 111b, which is the other end portion, with one end portion 111a as a fulcrum.
The five lighting sections 130 are light source devices provided at positions corresponding to the five liquid containers 113, respectively. In the lighting section 130, a lighting-on state and a lighting-off state are switched under the control of the control section 30.
The lock mechanism 112 is a mechanism capable of switching the cover member 111 between a first state where the cover member 111 cannot transition from the closed state to the open state and a second state where the cover member 111 can transition from the closed state to the open state. In the present embodiment, the lock mechanism 112 is a plate-like member provided above the carriage 110, and can attain the first state by restricting the operation of the user to the operation section 111b due to the cover of the operation section 111b. The plate-like member has an opening 112a for exposing the operation section 111b.
In
The notification section 120 notifies a user of replenishment of the liquid or related information using a residual amount of liquid under the control of the control section 30. The related information includes, for example, a time required for replenishment of the liquid, the number of times of printing when the liquid in the liquid supply container 200 is completely replenished, and whether or not an amount of liquid in the liquid container 113 enables the completion of the replenishment. In the present embodiment, the notification section 120 is a display device, but not limited to this, for example, a voice device such as a speaker may be used.
The waste liquid tank 117 is a container that stores a liquid ejected from the print head 115 and not used for printing. For example, the waste liquid tank 117 communicates with a cleaning mechanism (not illustrated) that sucks the liquid from the print head 115. The liquid in the print head 115 sucked by the cleaning mechanism circulates in the waste liquid tank 117. The waste liquid tank 117 is a replaceable attaching/detaching member and is a consumable item that is replaced with a new waste liquid tank 117 when a predetermined amount of liquid is stored.
As illustrated in
Subsequently, the determination section 20 determines in Step S120 whether or not the liquid supply container 200 can be recognized from the captured image acquired in Step S100. That is, for example, the user determines whether or not to dispose the liquid supply container 200 in the area of an object to be imaged by the imaging device 300. When the liquid supply container 200 can be recognized, the processing proceeds to Step S130. On the other hand, when the liquid supply container 200 cannot be recognized, the processing returns to Step S100. That is, the printing system 500 repeats the processing of Steps S100 to S120 until the liquid supply container 200 can be recognized. When a predetermined time has elapsed, the liquid replenishment processing may be ended.
The determination section determines in Step S130 whether or not the recognized liquid supply container 200 can be replenished with the liquid in the liquid container 113 to be replenished with the liquid. More specifically, the determination section 20 collates the image information of the liquid supply container 200 recognized in Step S120 with the reference information acquired in Step S110 and determines whether or not the liquid supply container 200 corresponds to the liquid container 113 to be replenished. For example, it is possible to adopt at least one or more conditions including first condition among the following conditions as determination conditions. The determination conditions are set in advance when the liquid replenishment processing is started.
First Condition
The liquid supply container 200 stores a liquid having a predetermined color.
Second Condition
The liquid supply container 200 stores a liquid equal to or more than a predetermined amount.
Third Condition
The liquid supply container 200 is a regular product.
It is possible to determine whether or not the first condition is satisfied using, for example, the second information in the image information.
It is possible to determine whether or not the second condition is satisfied by obtaining the amount of liquid stored in the liquid supply container 200 using, for example, the first information in the image information and the image information acquired in Step S100.
It is possible to determine whether or not the third condition is satisfied using, for example, the third information or the fourth information in the image information.
The determination condition can be made by appropriately combining the first condition and the second and third conditions or other conditions. The determination condition may be stored in the storage section 140 or may be stored in a device outside the printing device 100.
When the determination section 20 determines in Step S130 that the replenishment cannot be made, that is, the determination condition has not been satisfied, the processing proceeds to Step S145 and the control section 30 controls the notification section 120 to notify the user that the liquid supply container 200 does not store ink to be replenished, and the liquid replenishment processing is thus ended. On the other hand, when the determination section 20 determines that the replenishment can be made, that is, when the determination condition is satisfied, the processing proceeds to Step S140 and the control section 30 performs replenishing processing.
In the replenishing processing, the control section 30 controls the printing device 100 to replenish the liquid from the liquid supply container 200 to the liquid container 113 to be replenished. Specifically, as illustrated in
Further, in the replenishing processing, the control section 30 may control the notification section 120 to notify the user of the related information. For example, during the processing of Step S120, the determination section 20 determines information regarding the residual amount of liquid in the liquid supply container 200 based on the image information, and calculates a time when the residual amount of liquid is filled into the liquid container 113 at a predetermined filling amount, that is, a time required for replenishment. Then, the control section 30 may be notified by the notification section 120 of the calculated time required for replenishment. Further, the control section 30 may control the notification section 120 to notify the user of a guide suitable for replenishment work according to the captured image acquired by the imaging device 300, the captured image including an image showing a coupling state of the liquid supply container 200 and the liquid fill port 114 as the liquid inlet port.
Subsequently, the printing device 100 determines in step S150 whether or not the replenishment is completed, as illustrated in
Finally, the control section 30 performs the replenishment completion processing in Step S160. The replenishment completion processing is control processing performed by the control section 30 when the replenishment of the liquid from the liquid supply container 200 is completed. As the replenishment completion processing, for example, any one or more of the following processing can be adopted.
First Processing
The carriage 110 is returned to the home position
Second Processing
The replenishment completion is notified by the notification section 120
Third Processing
The lighting section 130 that has been lit is turned off
The replenishment completion processing can be made by appropriately combining the first to third processing or other processing. The replenishment completion processing is determined according to the replenishing processing in Step S140.
According to the printing system 500 of the present embodiment described above, since it can be determined whether or not the liquid can be supplied from the liquid supply container 200 using the image information acquired by the imaging device 300, the control section 30 performs determination without having a radio tag on the liquid supply container 200 and an uneven shape for determination. Therefore, an environment-friendly consumable item, specifically, the liquid supply container 200 can be used.
Since the image information includes the color information 201, the character information 202, and the code information 203, the control section 30 can accurately perform determination whether or not the liquid is supplied.
Since the printing system 500 includes a plurality of imaging devices 300, it is possible to image the liquid supply container 200 from a plurality of angles. Therefore, image information with higher accuracy can be acquired. Furthermore, by imaging the liquid supply container 200 from the plurality of angles, the determination section 20 can generate third-dimensional information on the liquid supply container 200 by using the captured image. As a result, when the actual liquid supply container is a three-dimensional liquid supply container 200 even if a photograph is shown that the liquid supply container 200 is in front of the imaging device 300, it is possible to prevent the determination section 20 from performing false recognition.
In the replenishing processing, since the control section 30 moves the carriage 110 to a coupling position where the liquid supply container 200 and the liquid container 113 can be coupled, it is possible to easily recognize a position where the user couples the liquid supply container 200.
Since the captured image includes an image showing the coupling state between the liquid supply container 200 and the liquid container 113, the user can acquire the replenishment work in real time. Therefore, it is possible to perform the guide suitable for the user's work.
Since the notification section 120 notifies the information regarding the coupling method of the liquid supply container 200 and the liquid container 113 according to the determination of the control section 30, it is possible to assist the user's replenishment work. Therefore, it is possible to prevent the user from performing the wrong work.
Since the lighting section 130 indicates a position of the liquid container 113 to which the liquid supply container 200 is coupled, the position where the user couples the liquid supply container 200 can be easily recognized.
Further, the liquid container 113 to which the liquid supply container 200 is coupled can be replenished with the liquid according to the determination of the determination section 20, such that the control section 30 moves the carriage 110 so that the cover member 111 can be opened and closed. As a result, it is possible to prevent the user from coupling the liquid supply container 200 to the liquid fill port 114 of the liquid container 113 that is not the original liquid container to be replenished.
According to the printing system 500 of the present embodiment described above, since it can be determined whether or not the liquid can be supplied from the liquid supply container 200A by using the image information acquired by the imaging device 300, the control section 30 performs determination without having a radio tag on the liquid supply container 200A and an uneven shape for determination. Therefore, an environment-friendly consumable item, specifically, the liquid supply container 200A, which is a cartridge, can be used.
According to the printing system 500 of the present embodiment described above, since it can be determined whether or not the liquid can be supplied from the liquid supply container 200 using the image information acquired by the imaging device 300, the control section 30 performs determination without having a radio tag on the liquid supply container 200 and an uneven shape for determination. Therefore, the liquid supply container 200, which is an environment-friendly consumable item, can be used. As a result, the user can replenish the liquid from the liquid supply container 200 to the liquid container 113 through the liquid fill port 114.
(D1)
(D2) In the embodiment, the processing of Steps S100 to S130 may be repeated since determining that the replenishment can be performed in the liquid replenishment processing until the replenishment is completed. That is, even if it is determined that the liquid supply container 200 stores the liquid to be replenished, it is repeatedly determined whether the liquid supply container 200 stores the liquid to be replenished until the replenishment is completed. According to the embodiment, it is possible to avoid the user from replenishing the ink with the different liquid supply containers 200 on the way.
(D3) In the embodiment, the printing device 100 may be notified to the user according to an amount of liquid stored in the liquid supply container 200. For example, by using an amount of liquid stored in the liquid supply container 200 included in the image information acquired by the imaging device 300, the printing device 100 can obtain a time required for replenishment completion or the number of times of printing and notify the user of the time required for replenishment completion or the number of times of printing.
(D4) In the liquid replenishment processing of the embodiment, the printing system 500 may replace an attaching/detaching member as another replaceable consumable item. The attaching/detaching member is, for example, the waste liquid tank 117, the lighting section 130, a display, or the like. The imaging device 300 acquires image information including at least a part of the attaching/detaching member, and the acquisition section 10 acquires reference information regarding the attaching/detaching member. The determination section 20 collates the image information with the reference information, and determines whether or not the attaching/detaching member can be replaced according to the collation result. The control section 30 controls the printing device 100 according to the determination of the determination section 20.

If technical features are not described as indispensable features in the present description, the technical features may be deleted as needed. In the first and third embodiments, the term “replenishment” means supplying the liquid from the liquid supply container 200 to increase a liquid level of the liquid container 113, means filling the empty liquid container 113 with the liquid when the printing device 100 is used first, and means increasing the liquid level in a state where the liquid remains in the liquid container 113. Due to the “replenishment”, the liquid level may not be necessarily increased to a full position.
