[Example 1]
Embodiments of the present invention will be described below with reference to the accompanying drawings. First, with reference to FIG. 1, an overview of a media processing device 100A according to a first embodiment of the present invention as a media processing device 100 will be described. 100 A of media processing apparatuses shown in FIG. 1 include a conveyance section 10 that conveys a fabric F, which is an example of a medium, in a conveyance direction A, a liquid jetting section 1 that injects a liquid 3 onto the fabric F conveyed by the conveyance section 10, It is equipped with The medium processing device 100A of this embodiment is a medium cleaning device that cleans the fabric F with the liquid 3 as the cleaning liquid jetted from the liquid jetting section 1.

The conveyance unit 10A of this embodiment as the conveyance unit 10 includes an endless conveyance belt 13 that supports the fabric F, and the conveyance belt 13 is hung and rotates in the rotation direction C, thereby rotating the conveyance belt 13 in the rotation direction C. and a driven roller 11 to which a conveyor belt 13 is stretched along with the drive roller 12 and which rotates as the conveyor belt 13 rotates. The conveyance unit 10 configured as in this embodiment, which includes an endless conveyor belt 13 that supports the fabric F and a drive roller 12 that rotates the conveyor belt 13, can suitably convey the fabric F and also can apply the liquid 3. Since the fabric F can be supported by the conveyor belt 13 at this position, the liquid 3 can be made to collide with the fabric F with a strong impact force.

Here, the liquid ejecting section 1 of the medium processing device 100 of the present invention, although a detailed configuration example will be described later, injects the liquid 3 in a continuous flow 3a onto the fabric F conveyed by the conveying section 10A, and This is a liquid ejecting unit that causes the liquid 3 ejected as a continuous flow 3a to collide with the fabric F in the form of droplets 3b. The liquid ejecting section 1A as the liquid ejecting section 1 of this embodiment has a nozzle section 2 having at least one ejection port 4a for ejecting the liquid 3. By configuring the liquid ejecting section 1 in this way, the liquid 3 can be suitably ejected from the liquid ejecting section 1.

Further, the medium processing apparatus 100A of this embodiment includes an ultrasonic wave generating section 20 in addition to the above-mentioned transport section 10A and liquid ejecting section 1A. Here, the ultrasonic wave generating section 20 of the present invention is connected to a control section such as a control section 5 to be described later, and adjusts the amount of liquid 3 ejected from the liquid ejection section 1A. The structure is such that the liquid 3 injected from the cloth F is held as a liquid film 3f in contact with the fabric F, and ultrasonic waves can be transmitted to the liquid film 3f as the held liquid 3.

The medium processing device 100A of this embodiment can apply a strong impact to the fabric F by causing the liquid 3 injected as a continuous flow 3a to collide with the fabric F in the form of droplets 3b. Furthermore, the medium processing device 100A of the present embodiment applies ultrasonic waves to the liquid film 3f, which is the liquid 3 held in contact with the fabric F, by the ultrasonic generator 20A, which is an example of the ultrasonic generator 20 of the present invention. can be transmitted, so the liquid 3 in contact with the fabric F can be vibrated by the ultrasonic waves, and the fabric F can be treated with the vibrated liquid 3. Therefore, the medium processing apparatus 100A of this embodiment can effectively improve cleaning of the fabric F as a medium processing. Moreover, the cleaning range of the fabric F, which serves as the medium processing range, can be extended not only to the droplet impact position but also to the surrounding range.

Here, the medium used in the medium processing apparatus 100A of this embodiment is the fabric F, as described above. When the medium is the fabric F, simply spraying the liquid 3 onto the medium may not provide a sufficient treatment effect of the liquid 3 on the medium. However, since the medium processing apparatus 100A of the present embodiment includes the ultrasonic generator 20 having the above-described configuration, even when the medium is the fabric F, the medium processing apparatus 100A can process the fabric F as a process for the medium. The cleaning process can be effectively improved.

Further, as shown in FIG. 1, the ultrasonic generator 20A of this embodiment as the ultrasonic generator 20 is configured to apply the liquid 3 from the liquid jet unit 1A to the fabric F at a position A in the conveying direction A. It is located on the downstream side. Therefore, ultrasonic waves can be transmitted after the liquid 3 is applied by colliding the droplets 3b, and the fabric F can be effectively cleaned by ultrasonic waves. Note that "downstream side in the transport direction A" means the leading end side in the direction of the arrow in the transport direction A, and conversely, "upstream side in the transport direction A" means the rear end side in the direction of the arrow in the transport direction A. .

Next, with reference to FIGS. 2 and 3, the configurations of the liquid ejecting section 1 and the ultrasonic generating section 20 will be further described in detail. As shown in FIG. 2, in the liquid ejecting unit 1A of this embodiment, the ejection ports 4a for the liquid 3 are arranged in one row on the ejection surface 4 over the entire width direction, which is the direction intersecting the conveying direction A of the fabric F. It has a plurality of nozzle parts 2 arranged in a line.

In this way, in the medium processing device 100A of this embodiment, the nozzle section 2 has the ejection surface 4 in which the ejection port 4a is formed. As shown in FIGS. 1 and 2, the ultrasonic generating section 20A of this embodiment is provided in the nozzle section 2 and extends beyond the ejection surface 4 in the ejection direction B of the liquid 3. Like the ultrasonic generator 20A of this embodiment, the ultrasonic generator can 20 and the liquid ejecting section 1 can be prevented from interfering with each other, and the overall configuration of the device can be downsized.

More specifically, as shown in FIGS. 1 and 2, the nozzle part 2 has a row of injection ports 4 formed on the injection surface 4 in which a plurality of injection ports 4a are lined up in a direction intersecting the conveyance direction A, and generates ultrasonic waves. The extending portion of the portion 20A is a flat member extending in the direction along the injection port array. With such a configuration, the ultrasonic wave generator 20 and the application position of the liquid 3 injected from the nozzle array can be brought close to each other, and the ultrasonic waves can be effectively transmitted to the liquid film 3f. Although the nozzle section 2 of this embodiment has one row of injection ports, the nozzle section 2 may have a plurality of injection ports instead of one row.

In addition, although the extension part of 20 A of ultrasonic wave generating parts of a present Example protrudes linearly along the injection direction B, as shown in FIG. 1, it is not limited to such a structure. For example, the extending portion of the ultrasonic generator 20 may curve and protrude toward the downstream side in the conveyance direction A. With such a configuration, it is possible to reduce the possibility of damaging the fabric F when the extending part of the ultrasonic generating part 20 comes into contact with the fabric F, and also to prevent the extending part of the ultrasonic generating part 20 from being placed at the application position of the liquid 3. The exit part can be moved closer.

Further, as shown in FIG. 3, the liquid ejecting section 1A of this embodiment includes a nozzle section 2 having at least one ejection port 4a for ejecting the liquid 3, and a tube for conveying the liquid 3 to the ejection port 4a. The liquid transport section 7 has a pressure section 6 that pressurizes the liquid 3 in the liquid transport section 7. With such a configuration, the liquid ejecting unit 1 injects the liquid 3 in a continuous flow 3a and causes the liquid 3 injected as the continuous flow 3a to collide with the fabric F in a state where the liquid 3 becomes droplets 3b. can be suitably formed.

In this way, the liquid ejecting section 1A of this embodiment is capable of producing a liquid in which the continuous flow 3a of the liquid 3 continuously injected in the ejection direction B from the plurality of ejection ports 4a provided in the nozzle section 2 becomes droplets 3b. The liquid ejecting device is characterized in that the liquid droplets 3b collide with the target object, the fabric F, in a droplet state. As the liquid 3, water can be preferably used, as well as water containing detergents such as surfactants, aqueous solutions containing various solvents and additives using water as a solvent, volatile organic solvents, etc. , can be used without particular limitation.

Here, the liquid transport section 7, which serves as a liquid sending channel that connects the liquid storage section 8 to the nozzle section 2, can be constructed using a soft resin material or the like to improve handling properties. The pressurizing section 6 is driven under the control of the control section 5 connected via a control signal line 9, and feeds the liquid 3 at a predetermined pressure or a predetermined flow rate. Note that the pressure or flow rate can be arbitrarily changed by inputting an instruction to the control unit 5 by the user. Expressed in another way, the control unit 5 can control the amount of the liquid 3 injected from the liquid injection unit 1 . Therefore, the liquid 3 can be automatically ejected from the liquid ejecting section 1 at a preferable ejection amount. Note that a filtering mechanism may be provided between the liquid storage section 8 and the nozzle section 2, and the liquid 3 that has washed the fabric F may be collected into the liquid storage section 8 and circulated. With such a configuration, it is possible to save the liquid 3.

On the other hand, as shown in FIG. 4, the ultrasonic generating section 20B of the medium processing apparatus 100B of this embodiment is a flat member extending in the direction along the jet nozzle row like the ultrasonic generating section 20A. The extending portion is arranged on the upstream side in the transport direction A from the position P1 where the liquid 3 is applied to the fabric F from the liquid jetting portion 1A. Therefore, the position where the liquid 3 is applied can be set in advance in a state where ultrasonic waves are transmitted.

Here, in the medium processing apparatus 100 of the first embodiment and the present embodiment, the transport section 10A is provided in a position located above in the direction of gravity from the upstream side to the downstream side in the transport direction A. Therefore, the liquid film 3f tends to drip more upstream in the transport direction A than the application position P1 of the liquid 3. Therefore, the ultrasonic wave is transmitted to the application position of the liquid 3 in advance by the ultrasonic wave generator 20A, which is arranged upstream of the application position P1 of the liquid 3 in the transport direction A and is configured to contact the liquid film 3f. It is now easier to leave it as it is.

However, the configuration is not limited to this. For example, even if the conveyance section 10 is arranged horizontally from the upstream side to the downstream side in the conveyance direction A, the liquid film 3f spreads horizontally based on the application position of the liquid 3, so that ultrasonic waves are generated. Even if the portion 20 is configured to come into contact with the liquid film 3f, it is possible to set the position where the liquid 3 is applied in advance in a state where ultrasonic waves are transmitted. In addition, when the ultrasonic wave generator 20 is configured not to directly contact the liquid film 3f and transmit the ultrasonic waves, but to contact only the fabric F and indirectly transmit the ultrasonic waves to the liquid film 3f, It is possible to transmit ultrasonic waves to the liquid 3 held on the fabric F regardless of the spread of the liquid film 3f. The arrangement of the ultrasonic generator 20 is not particularly limited as long as it can transmit ultrasonic waves to the liquid 3 held on the fabric F.
