The present application is based on, and claims priority from JP Application Serial Number 2022-178117, filed Nov. 7, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to an adhesive removing device and a recording device.
An example of this type of device is disclosed in JP-A-2021-109736. JP-A-2021-109736 discloses an adhesive layer removing device in which when an adhesive force of an adhesive layer adhering to a front surface of an endless belt that rotates is reduced, an adhesive layer is formed again. It is described that the adhesive layer removing device includes a solvent applying unit that applies a solvent that dissolves the adhesive layer having a reduced adhesive force in order to efficiently remove the adhesive layer, a swelling promoting unit that promotes swelling of the adhesive layer through permeation of the solvent, and a scraper that scrapes the dissolved adhesive layer.
However, a scraper for scraping an adhesive is different in required scraping performance such as appropriate rigidity according to the type and the deterioration state of the adhesive, but the adhesive layer removing device of JP-A-2021-109736 cannot structurally cope therewith. Thus, it has been difficult to efficiently remove the adhesive.
To solve the above problem, an adhesive removing device according to the present disclosure includes a scraping member configured to scrape an adhesive layer adhering to a front surface of a belt configured to transport a transport target object, and a support portion configured to support the scraping member, the support portion being configured to support the scraping member such that a support state of the scraping member is changeable.
Moreover, a recording device according to the present disclosure includes a belt including a front surface to which an adhesive layer adheres, the belt being configured to transport a medium, a recording unit configured to perform recording on the medium transported by the belt, and an adhesive removing device configured to remove the adhesive layer from the front surface of the belt, wherein the adhesive removing device is the adhesive removing device according to any one of first to eighth aspects described below.
Hereinafter, the present disclosure will be schematically described first.
To solve the above problem, an adhesive removing device according to a first aspect of the present disclosure includes a scraping member configured to scrape an adhesive layer adhering to a front surface of a belt configured to transport a transport target object, and a support portion configured to support the scraping member, the support portion being configured to support the scraping member such that a support state of the scraping member is changeable.
Here, the expression “scrape an adhesive layer” means that the belt moves in a transport direction relative to the scraping member in a state in which the scraping member is in contact with the adhesive layer adhering to the front surface of the belt, so that the adhesive layer is removed so as to be scraped off the front surface of the belt.
According to this aspect, the support portion that supports the scraping member supports the scraping member such that the support state of the scraping member is changeable. Accordingly, since the support state of the scraping member can be changed, the change can be performed according to the type of the adhesive and the deterioration state of the adhesive layer, and thus the adhesive layer can be scraped with efficient scraping performance.
An adhesive removing device according to a second aspect of the present disclosure is the adhesive removing device according to the first aspect, wherein the support portion is configured to support different types of the scraping members in a replaceable manner.
According to this aspect, the support portion supports the different type of the scraping member in a replaceable manner. This can easily change the support state of the scraping member by replacing the scraping member with the different type of the scraping member.
An adhesive removing device according to a third aspect of the present disclosure is the adhesive removing device according to the second aspect, wherein the scraping member is a scraper having a plate shape, and the adhesive removing device includes a curve forming portion configured to curve the scraper when the scraper is supported by the support portion.
According to this aspect, the curve forming portion curves the plate-shaped scraper having low rigidity, which can easily increase the rigidity of the scraper. Thus, the scraper, which has low rigidity in a non-curved state, is curved to have increased rigidity, and thus the scraper can be pressed against and come into firm contact with the belt. Accordingly, the adhesive layer can be scraped in a state in which the belt is less likely to be damaged.
An adhesive removing device according to a fourth aspect of the present disclosure is the adhesive removing device according to the third aspect, wherein the curve forming portion includes a plurality of members.
According to this aspect, since the curve forming portion includes the plurality of members, it is possible to easily bring the scraper into a desired curved state by arranging the plurality of members such as cylindrical bodies in accordance with the degree of curve.
An adhesive removing device according to a fifth aspect of the present disclosure is the adhesive removing device according to the second aspect, including an adhesive layer receiving portion configured to receive the adhesive layer scraped by the scraping member.
According to this aspect, since the adhesive layer receiving portion that receives the adhesive layer scraped by the scraping member is provided, the scraped adhesive layer can be easily collected.
An adhesive removing device according to a sixth aspect of the present disclosure is the adhesive removing device according to the second aspect, wherein the scraping member is a scraper having a plate shape, and a portion of the scraper configured to make contact with the belt for scraping is formed into a protruding curve shape.
According to this aspect, the portion of the scraper that performs scraping in contact with the belt is formed into the protruding curve shape. That is, the contact position of the scraping portion of the scraper with respect to the belt changes along the protruding curve shape. Thus, the scraping of the adhesive layer starts at the top position of the protruding curve shape, and the scraping position expands along the protruding curve shape, so that the adhesive layer can be scraped without difficulty.
An adhesive removing device according to a seventh aspect of the present disclosure is the adhesive removing device according to the third aspect, including a position adjustment portion configured to vertically adjust a position of a portion of the scraper configured to make contact with the belt for scraping.
According to this aspect, the position of the portion of the scraper that performs scraping in contact with the belt can be vertically adjusted by the position adjustment portion. Accordingly, the rigidity of the scraper can be easily adjusted, and thus the support state of the scraping member can be easily changed.
An adhesive removing device according to an eighth aspect of the present disclosure is the adhesive removing device according to the second aspect, including a rail extending in a width direction of the belt, wherein the support portion is configured to move along the rail.
According to this aspect, the rail extending in the width direction of the belt is provided, and the support portion is configured to move along the rail. Thus, by moving the support portion along the rail, the scraping can be easily performed over the entire width of the belt.
A recording device according to a ninth aspect of the present disclosure includes a belt including a front surface to which an adhesive layer adheres, the belt being configured to transport a medium, a recording unit configured to perform recording on the medium transported by the belt, and an adhesive removing device configured to remove the adhesive layer from the front surface of the belt, wherein the adhesive removing device is the adhesive removing device according to any one of the first to eighth aspects.
According to this aspect, the same effect as that of any of the first to eighth aspects can be obtained as the recording device.
Hereinafter, an adhesive removing device according to each embodiment of the present disclosure and a recording device such as an inkjet printer including this adhesive removing device will be specifically described with reference to the drawings.

Adhesive Removing Device
As illustrated in
In the first embodiment, the adhesive removing device 11 includes a scraping member 13 that scrapes the adhesive layer 3 adhering to the front surface of the belt 7 that transports the medium 5, which is a transport target object, and a support portion 15 that supports the scraping member 13. The support portion 15 is configured to support the scraping member 13 such that a support state of the scraping member 13 is changeable.
Here, the expression “scrapes the adhesive layer 3” means that the belt 7 moves in the transport direction F relative to the scraping member 13 in a state in which the scraping member 13 is in contact with the adhesive layer 3 adhering to the front surface of the belt 7, so that the adhesive layer 3 is removed so as to be scraped off the front surface of the belt 7.
In addition, a specific structure in which the support portion 15 supports the scraping member 13 such that the support state of the scraping member 13 is changeable will be described below.
As illustrated in
The adhesive removing device 11 further includes a box-shaped adhesive layer receiving portion 19 for receiving the adhesive layer 3 scraped by the scraping member 13.
As illustrated in
In the case of a structure in which the support portion 15 is fixed to the outer surface 14 of the adhesive layer receiving portion 19, the adhesive layer 3 scraped by the scraping member 13 is less likely to enter the adhesive layer receiving portion 19 than in the case where the support portion 15 is fixed to the inner surface 12 as illustrated in
In the first embodiment, the adhesive layer receiving portion 19 is configured to be movable in the width direction of the belt 7 (X-axis direction) along the rail 17. Although a structure is employed in which the adhesive layer receiving portion 19 is manually moved along the rail 17, the adhesive layer receiving portion 19 may be configured to be movable by means of a driving mechanism (not illustrated) transmitting power of a driving source such as a motor using a power transmission mechanism.
In the first embodiment, since the support portion 15 supporting the scraping member 13 is fixed to the inner surface 12 (
In addition, the support portion 15 may have a structure of moving directly along the rail 17 without interposing the adhesive layer receiving portion 19 therebetween.
In the first embodiment, both ends of the rail 17 are coupled to a structural member (not illustrated) holding the bearings 6 and 8 via coupling members (not illustrated) and the rail 17 can be mounted at a predetermined position with respect to the belt 7. As a result, the adhesive removing device 11 can scrape and remove the adhesive layer 3 of the belt 7. When the adhesive removing device 11 is not in use, the coupling members can be removed from the structural member, so that the adhesive removing device 11 can be removed from the recording device 1. As a result, the adhesive removing device 11 can be kept at another place.
When the adhesive removing device 11 does not interfere with use of the recording device 1 in a state in which the adhesive removing device 11 is coupled to the recording device 1, it is needless to say that the adhesive removing device 11 may remain coupled.
Further, the “predetermined position” of the rail 17 with respect to the belt 7 may not be a fixed position but may be a variable position. The scraping member 13 may be also supported by the support portion 15 such that the contact angle with respect to the belt 7 is changeable.
In addition, it is needless to say that the structure in which the adhesive removing device 11 can scrape and remove the adhesive layer 3 of the belt 7 is not limited to the structure in which the adhesive removing device 11 is mounted along the structural member via the coupling members. For example, leg portions may be provided at both end portions of the rail 17 so as to enable the adhesive layer 3 of the belt 7 to be scraped and removed with the leg portions fixed to a floor or the like.
In the first embodiment, as a specific structure capable of changing the support state of the scraping member 13, the support portion 15 is configured to support a different type of scraping member 13 in a replaceable manner.
The different type of scraping member 13 means that the scraping member 13 is replaced with another one different in the shape, thickness, material, and the like in accordance with the type of the adhesive and the deterioration state of the adhesive layer 3 so that the adhesive layer 3 can be scraped with efficient scraping performance.
The structure capable of changing the support state of the scraping member 13 is not limited to the above-described structure capable of replacing the scraping member 13 with a different type of scraping member 13. For example, a structure in which the contact angle of the scraping member 13 supported by the support portion 15 with respect to the belt 7 is variable or a structure in which the protruding length of the scraping member 13 from the support portion 15 is variable may be employed.
In the first embodiment, the scraping member 13 includes a plate-shaped scraper 13 (denoted by the same reference numeral 13). Further, as illustrated in
Further, in the scraper 13, a portion 23 that performs scraping in contact with the belt 7 is formed into a protruding curve shape 25. The protruding curve shape 25 is formed such that a central portion in the width direction (X-axis direction) of the portion 23 that performs scraping in contact with the belt 7 protrudes most, in other words, the central portion is formed at a top position 16. The scraper 13 starts scraping the adhesive layer 3 of the belt 7 from the top position 16, and the scraping position expands along the protruding curve shape 25.
The specific structure in which the support portion 15 supports the scraper 13 via the curve forming portion 21 is drawn small in
Examples of the scraper 13 having different shapes will be described with reference to
In
In the first embodiment, as illustrated in
Next, a specific structure in which the support portion 15 supports the scraper 13 via the curve forming portion 21, inclusive of the structure of the position adjustment portion 27, will be described with reference to
As illustrated in
As illustrated in
Push-in screws 40 and 42 are screwed into both ends of the base portion 38 of the support portion 15. The push-in screws 40 and 42 are turned and pushed in, and thus the scraper 13 is curved and deformed so as to come into contact with the curve forming surface 46 of the curve forming portion 21. Accordingly, the scraper 13 is deformed into a curve shape that protrudes in the −Y direction, and the scraper 13 in the curve shape is supported by the support portion 15.
As illustrated in
As illustrated in
As illustrated in
In a case where the contact angle of the scraper 13 with respect to the belt 7 is configured to be variable, the angle can be adjusted to an appropriate angle when the position of the scraping portion 23 of the scraper 13 is vertically moved and adjusted.
Description of Effects of First Embodiment
(1) In the first embodiment, the support portion 15 that supports the scraping member 13 supports the scraping member 13 such that the support state of the scraping member 13 is changeable. Thus, since the support state of the scraping member 13 can be changed, the change can be performed according to the type of the adhesive and the deterioration state of the adhesive layer 3, which enables the adhesive layer 3 to be scraped with efficient scraping performance.
(2) Further, in the first embodiment, the support portion 15 supports a different type of scraping member 13 in a replaceable manner. Thus, the support state of the scraping member 13 can be easily changed by replacing the scraping member 13 with the different type of scraping member 13.
(3) Further, in the first embodiment, the curve forming portion 21 curves the plate-shaped scraper 13 having low rigidity, thereby easily enabling the rigidity to increase. This enables the scraper 13, which has low rigidity in a non-curved state, to be pressed against and brought into firm contact with the belt 7 in a state where the scraper 13 is curved to have increased rigidity. Thus, it is possible to scrape the adhesive layer 3 in a state where the belt 7 is less likely to be damaged.
(4) In addition, in the first embodiment, since the adhesive layer receiving portion 19 that receives the adhesive layer 3 scraped by the scraping member 13 is provided, the scraped adhesive layer 3 can be easily collected.
(5) Further, in the first embodiment, the portion 23 of the scraper 13 that performs scraping in contact with the belt 7 is formed into the protruding curve shape 25. That is, the contact position of the scraping portion 23 of the scraper 13 with respect to the belt 7 changes along the protruding curve shape 25. Thus, the scraping of the adhesive layer 3 starts at the top position 16 of the protruding curve shape 25, and the scraping position expands along the protruding curve shape 25, so that the adhesive layer 3 can be scraped without difficulty.
(6) In the first embodiment, the position of the portion 23 of the scraper 13 that performs scraping in contact with the belt 7 can be vertically adjusted by the position adjustment portion 27. Accordingly, the rigidity of the scraper 13 can be easily adjusted, and thus the support state of the scraping member 13 can be easily changed.
(7) Further, in the first embodiment, the rail 17 extending in the width direction of the belt 7 is provided, and the support portion 15 is movable along the rail 17. Thus, by moving the support portion 15 along the rail 17, the scraping can be easily performed over the entire width of the belt 7.
Next, an adhesive removing device 11 according to a second embodiment will be described with reference to
A curve forming portion 21 of the adhesive removing device 11 of the second embodiment is not a single body as in the first embodiment, but includes a plurality of members. Specifically, the five curve forming portions 21 having a cylindrical shape are arranged separately from each other and are configured such that the scraper 13 is curved by all of the five curve forming portions 21. It is needless to say that the plurality of members are not limited to those having a cylindrical shape and may have any structure as long as the scraper 13 can be curved by all of the plurality of members.
According to the second embodiment, the curve forming portion 21 includes the plurality of members. That is, since the plurality of members having a cylindrical shape or the like can be arranged in accordance with the degree of curve of the scraper 13, the scraper 13 can be easily brought into a desired curved state.
The adhesive removing device 11 and the recording device 1 including the adhesive removing device 11 according to the present disclosure is based on the configurations of the embodiments described above. However, as a matter of course, modifications, omission, and the like may be made to a partial configuration without departing from the gist of the disclosure of the present application.
In the above-described embodiments, the recording device 1 has been described as a device including the adhesive removing device. However, devices other than the recording device may include the adhesive removing device. That is, the present disclosure is also applicable to other devices having a structure of transporting the medium 5 with the medium 5 sticking to the adhesive layer 3 of the belt 7.
In the above-described embodiments, the case where the support portion 15 supports one scraper 13 has been described. However, the support state of the scraper 13 may be changed by the support portion 15 supporting two or more scrapers in an overlapping manner.
