Description

[Technical field]

[0001] The present invention relates to a transport device and a recording device. [Background technology]

[0002] Conventionally, various conveying devices have been used. Among them, there is a conveying device that includes a conveying belt that supports and conveys a medium on its outer peripheral surface, and a blade that can wipe the outer peripheral surface. For example, Patent Document 1 discloses an inkjet recording device that includes a conveying belt that supports and conveys a medium on its outer peripheral surface, and a secondary wiping blade that can contact the surface of the conveying belt and wipe the outer peripheral surface.

[0003] [Patent Document 1] JP 2014-47034 A Summary of the Invention [Problem to be solved by the invention]

[0004] The inkjet recording device of Patent Document 1 further includes a secondary fixing plate to which the secondary wiping blade is fixed with screws, a secondary pressing member that presses the base end of the secondary wiping blade against the secondary fixing plate, and a plurality of secondary fixing screws that fasten the secondary pressing member to the secondary fixing plate. In a device configured in this way, the reaction force against the conveyor belt depends only on the elasticity of the blade. In other words, the degree of freedom between the conveyor belt and the blade, which corresponds to the reaction force against the conveyor belt required for the device, is narrow. In this way, in a conventional conveyor device with a narrow degree of freedom between the conveyor belt and the blade, the ease of assembly when assembling the device, such as installing the conveyor belt, is easily reduced. [Means for solving the problem]

[0005] In order to solve the above problem, the conveying device of the present invention is characterized in that it comprises a conveying belt having an outer peripheral surface that supports a medium and is capable of conveying the medium, a blade that is capable of wiping the outer peripheral surface by contacting the outer peripheral surface, a first frame that holds the blade, an elastic member that biases the first frame in a direction in which the blade contacts the outer peripheral surface, and a second frame that supports the first frame movably along a normal direction of the outer peripheral surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] First, the present invention will be briefly described. In order to solve the above problem, a conveying device of a first aspect of the present invention is characterized in that it comprises a conveying belt having an outer peripheral surface that supports a medium and is capable of conveying the medium, a blade that is capable of wiping the outer peripheral surface by contacting the outer peripheral surface, a first frame that holds the blade, an elastic member that biases the first frame in a direction in which the blade contacts the outer peripheral surface, and a second frame that supports the first frame movably along a normal direction of the outer peripheral surface.

[0008] According to this aspect, the device includes a first frame that holds the blade, an elastic member that biases the first frame in a direction in which the blade contacts the outer peripheral surface, and a second frame that supports the first frame movably along the normal direction of the outer peripheral surface. By configuring the device to include an elastic member in this way, it is possible to increase the degree of freedom between the conveyor belt and the blade, and by configuring the second frame to support the first frame movably along the normal direction of the outer peripheral surface, it is possible to particularly increase the gap between the conveyor belt and the blade. Therefore, it is possible to improve the ease of assembly of the device.

[0009] A second aspect of the transport device of the present invention is an aspect dependent on the first aspect, characterized in that the elastic member is a spring.

[0010] According to this aspect, the elastic member is a spring, and with this configuration, the elastic member can be made to have a simple configuration at low cost.

[0011] A conveying device according to a third aspect of the present invention is an aspect dependent on the second aspect, characterized in that the spring has an attachment portion that can be attached to the first frame and the second frame.

[0012] According to this aspect, the spring has an attachment portion that can be attached to the first frame and the second frame. With this configuration, the elastic member can be attached to the first frame and the second frame, and the second frame that supports the first frame movably along the normal direction of the outer peripheral surface can be easily configured.

[0013] A fourth aspect of the conveying device of the present invention, in an aspect dependent on the first aspect, is characterized in that the elastic member is attached to the first frame and the second frame and is detachable from the first frame and the second frame.

[0014] According to this aspect, the elastic member is attached to the first frame and the second frame and is detachable from the first frame and the second frame. With this configuration, the elastic member can be easily attached to the first frame and the second frame, and the assemblability of the device can be particularly improved.

[0015] A fifth aspect of the present invention is a transport device dependent on the fourth aspect, characterized in that the first frame is capable of mounting a plurality of the elastic members.

[0016] According to this aspect, a plurality of elastic members can be attached to the first frame. With this configuration, for example, by changing the number or type of elastic members attached to each first frame, it is possible to bias the blade against the outer circumferential surface with an appropriate biasing force.

[0017] A sixth aspect of the conveying device of the present invention is an aspect dependent on the fifth aspect, characterized in that a plurality of the first frames are connected to one of the second frames via the elastic member.

[0018] According to this aspect, a plurality of first frames are connected to one second frame via an elastic member. With this configuration, the second frame can easily support each of the first frames movably along the normal direction of the outer peripheral surface, improving the ability of the first frames to follow the outer peripheral surface. This improves the effect of the blade wiping the outer peripheral surface.

[0019] A seventh aspect of the present invention is a transport device dependent on the first aspect, characterized in that the transport device further comprises a sliding member between the first frame and the second frame.

[0020] According to this aspect, the sliding member is provided between the first frame and the second frame, which makes it easier for the first frame to move relative to the second frame.

[0021] The recording device of the eighth aspect of the present invention is characterized in that it comprises a conveying device described in any one of the first to seventh aspects and a recording unit capable of recording on the medium transported by the conveying belt.

[0022] According to this aspect, recording is performed on the medium transported by the transport unit of the transport device, and therefore, it is possible to record on the medium using a recording device with improved assembly efficiency.

[0023] [Example 1] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. First, an overview of a recording apparatus 1A according to a first embodiment, which is both a conveying apparatus 1 and a recording apparatus 1 of the present invention, will be described with reference to FIG.

[0024] As shown in Figure 1, the recording device 1A of this embodiment is equipped with a holding unit 80 capable of rotatably holding a roll body R on which medium M is wound in a roll shape, and a transport unit 20 having a drive unit 40 which is a motor, and which transports the medium M unwound from the holding unit 80 in a transport direction A by the driving force of the drive unit 40.

[0025] The holding unit 80 includes a holding shaft 2 that holds the roll R and is passed through a paper tube that constitutes the rotation shaft of the roll R. The holding unit 80 is capable of rotating the holding shaft 2 in a rotation direction C to unwind the medium M from the roll R to the transport unit 20. The recording device 1A of this embodiment also includes a pressure roller 6 that presses the medium M against the transport belt 5 in an area facing the transport belt 5 that constitutes the transport unit 20. However, a configuration without the pressure roller 6 may also be used.

[0026] The transport unit 20 includes a driven roller 3 located upstream in the transport direction A, a driving roller 4 located downstream in the transport direction A, and a transport belt 5 which is an endless belt stretched between the driven roller 3 and the driving roller 4. Here, the transport belt 5 is an adhesive belt having an outer peripheral surface 5a in which an adhesive is applied to the support surface for the medium M which is the outer surface.

[0027] 1, with the medium M attached to the outer peripheral surface 5a, the medium M is supported by and transported on the transport belt 5. In the recording device 1A of this embodiment, the medium support region of the transport belt 5 that supports the medium M is the upper region bridged by the driven roller 3 and the driving roller 4. The driving roller 4 is a roller that rotates in a rotation direction C by the driving force of the driving unit 40, which is a motor, and the driven roller 3 is a roller that rotates by being driven by the rotation of the transport belt 5 that accompanies the rotation of the driving roller 4.

[0028] Moreover, the recording device 1A of this embodiment includes a carriage 100 capable of reciprocating in the width direction B of the conveyor belt 5, and a head 101 attached to the carriage 100. The head 101 is a recording unit capable of recording an image by ejecting liquid ink onto a medium M conveyed in a conveying direction A based on recording data.

[0029] The recording device 1A of this embodiment is capable of forming an image by ejecting ink from the head 101 onto the transported medium M while moving the carriage 100 back and forth in a width direction B intersecting the transport direction A. By being equipped with the carriage 100 configured in this manner, the recording device 1A of this embodiment is capable of forming a desired image on the medium M by repeating the process of transporting the medium M in the transport direction A by a predetermined transport amount and ejecting ink while moving the carriage 100 in the width direction B with the medium M stopped.

[0030] As described above, the recording device 1A of this embodiment is equipped with a so-called serial head type ejection head in which the head 101 mounted on the carriage 100 moves back and forth in the width direction B. However, the present invention is not limited to such an ejection head. For example, the head 101 may be fixed and extended in the width direction B, and may be a line head type recording unit in which a plurality of nozzles that eject ink along the width direction B are arranged. In addition, in the case of a configuration equipped with a line head type recording unit, the medium M can be transported by so-called continuous transport in which the medium M is transported continuously, rather than by so-called intermittent transport in which the medium M is transported by a predetermined transport amount and the medium M is stopped, as in the recording device 1A of this embodiment.

[0031] When the medium M on which an image is formed by ejecting ink from the head 101 is ejected from the recording device 1A of this embodiment, it is sent to a drying device that volatilizes the ink components ejected onto the medium M, or a winding device that winds up the medium M on which the image is formed, which are provided downstream of the recording device 1A of this embodiment.

[0032] Here, a printable material can be preferably used as the medium M. The printable material refers to fabrics, clothing, and other clothing products that are the subject of printing. Fabrics include woven fabrics, knitted fabrics, and nonwoven fabrics made of natural fibers such as cotton, silk, and wool, chemical fibers such as nylon, and composite fibers that are a mixture of these. Clothes and other clothing products include sewn T-shirts, handkerchiefs, scarves, towels, carrier bags, cloth bags, curtains, sheets, bed covers, and other furniture, as well as fabrics that exist as parts before and after cutting, etc. In addition to the above-mentioned printable materials, plain paper, fine paper, and paper dedicated to inkjet recording such as glossy paper can also be used.

[0033] When a printable material is used as the medium M, the printable material is prone to ink strike-through, which is a phenomenon in which ink ejected onto the medium M seeps through to the back surface, and the conveyor belt 5 may become dirty with ink. Therefore, the recording device 1A of this embodiment is provided with a cleaning unit 9 for cleaning ink that has struck through and adhered to the conveyor belt 5. The cleaning unit 9 of this embodiment is provided with a blade forming unit 90, the details of which will be described later, a storage tank 14 for storing cleaning liquid, a cleaning roller 10 that is immersed in the cleaning liquid and comes into contact with the conveyor belt 5, a blade 11 that is extended in the width direction B and wipes off the cleaning liquid that has adhered to the conveyor belt 5, and an absorbing roller 16 that absorbs the cleaning liquid that has not been wiped off by the blade 11. The direction in which the conveyor belt 5 rotates when the recording device 1A of this embodiment conveys the medium M in the conveying direction A is the rotation direction C, and the direction in which the conveyor belt 5 moves relative to the blade forming unit 90 at that time is the movement direction D.

[0034] Next, the blade forming section 90 of the cleaning section 9, which is a main part of the recording apparatus 1A of this embodiment, will be described in detail with reference to Fig. 2 to Fig. 10. As described above, the recording apparatus 1A of this embodiment includes the conveyor belt 5 having an outer peripheral surface 5a for supporting the medium M and capable of conveying the medium M, and the blade 11 capable of wiping the outer peripheral surface 5a by contacting the outer peripheral surface 5a. As shown in Figs. 2 to 7, the recording apparatus 1A of this embodiment includes, as the blade forming section 90, in addition to the blade 93, a first frame 91 having metal plates 96a and 96b and holding the blade 93 with the metal plates 96a and 96b, a metal plate 94 extending in the width direction B, and a second frame 92 fixed to the metal plate 94 with a plurality of screws 97 and extending in the width direction B.

[0035] Here, the second frame 92 supports the first frame 91 movably along the vertical direction corresponding to the normal direction of the outer peripheral surface 5a. Furthermore, the recording device 1A of this embodiment includes, as the blade forming section 90, a spring 95 which is an elastic member connected to the first frame 91 and the second frame 92 and biases the first frame 91 against the second frame 92 in the vertically upward direction in which the blade 93 contacts the outer peripheral surface 5a.

[0036] Thus, the recording device 1A of this embodiment includes a first frame 91 that holds the blade 93, a spring 95 as an elastic member that biases the first frame 91 in a direction in which the blade 93 contacts the outer peripheral surface 5a, and a second frame 92 that supports the first frame 91 movably along the normal direction of the outer peripheral surface 5a. The recording device 1A of this embodiment is configured to include an elastic member in this way, thereby making it possible to increase the degree of freedom between the conveyor belt 5 and the blade 93. Furthermore, the recording device 1A of this embodiment is configured such that the second frame 92 supports the first frame 91 movably along the normal direction of the outer peripheral surface 5a, thereby making it possible to particularly increase the degree of freedom between the conveyor belt 5 and the blade 91. Therefore, the recording device 1A of this embodiment is easy to assemble. Furthermore, the recording device 1A of this embodiment is configured such that the second frame 92 supports the first frame 91 movably along the normal direction of the outer peripheral surface 5a, thereby making it possible to efficiently apply the force of the blade 93 to the conveyor belt 5.

[0037] As described above, the recording device 1A of this embodiment includes the head 101 as a recording unit capable of recording on the medium M transported by the transport belt 5. That is, recording is performed on the medium M transported by the transport belt 5. Therefore, the recording device 1A of this embodiment can record on the medium M in the recording device 1 with improved assembly properties.

[0038] Here, the recording device 1A of this embodiment is configured such that the second frame 92 supports the first frame 91 movably along the normal direction of the outer peripheral surface 5a, thereby making it possible to particularly increase the degree of freedom between the conveyor belt 5 and the blade 91. The recording device 1A of this embodiment shown in FIG. 7 can adjust the distance between the blade 93 and the outer peripheral surface 5a to be reduced by a length L1 by the blade 93 contacting the outer peripheral surface 5a and bending, and can adjust the distance between the blade 93 and the outer peripheral surface 5a to be reduced by a length L2 by the first frame 91 moving along the normal direction of the outer peripheral surface 5a relative to the second frame 92. On the other hand, the recording device 1 of the reference example shown in FIG. 9 can only adjust the length L1 associated with the blade 93 contacting the outer peripheral surface 5a and bending, since the first frame 91 is fixed to the second frame 92. This adjustment involves adjusting the position of the base of the blade 93 in the normal direction and the position of the outer peripheral surface 5a, based on the position where the tip of the blade 93 contacts the outer peripheral surface 5a when no biasing force is applied.

[0039] Therefore, in the recording device 1X of the reference example shown in FIG. 9, how close the blade 93 can be to the position of the outer peripheral surface 5a in the normal direction of the outer peripheral surface 5a, in other words, how long the overlap length with respect to the outer peripheral surface 5a can be, the overlap length can only be about 2.5 mm. FIG. 10 shows the relationship between the overlap length and the urging force applied to the outer peripheral surface 5a in the recording device 1X of the reference example shown in FIG. 9. In detail, it shows how much urging force is applied to the outer peripheral surface 5a with a width of 1960 mm (length in the width direction B is 1960 mm) when the overlap length is changed. Here, the overlap length indicates how far the tip of the blade 93 advances in the normal direction to the position of the outer peripheral surface 5a when the conveyor belt 5 is removed from the recording device 1.

[0040] In the recording device 1X of the reference example shown in FIG. 9, the overlap length changes only when the blade 93 comes into contact with the outer peripheral surface 5a and bends. Therefore, as shown in FIG. 10, the overlap length and the biasing force are proportional to each other. If the overlap length becomes too short, the biasing force may become too small due to design tolerances and variations in components. Therefore, the minimum biasing force is set to 100N. In other words, by setting the biasing force to 100N or more, the blade 93 can be bent appropriately and the cleaning liquid attached to the outer peripheral surface 5a can be effectively wiped off. However, if the biasing force becomes too large, the friction force between the blade 93 and the outer peripheral surface 5a becomes large, which may cause transport failure or increase power consumption due to an increase in the transport load.

[0041] For this reason, in the recording device 1X of the reference example shown in FIG. 9, the effective region is a region where the biasing force is in the range of 100N to 500N. The effective region is a region where the overlap range where the cleaning liquid attached to the conveyor belt 5 is not left unwiped when the blade 93 contacts the outer peripheral surface 5a overlaps with the biasing force where the conveying load generated by the blade 93 being biased against the outer peripheral surface 5 does not exceed the upper limit. Here, the overlap range is in the range of 0.5mm to 2.5mm, but it is preferable that the upper limit value of 2.5mm is larger. If the overlap range is narrow, the biasing force is too small due to design tolerances and variations in components, and it may cause unwiped areas. In addition, it is preferable that the upper limit value of the biasing force, 500N, is smaller. If the biasing force is too large, it may cause conveying failure or increase power consumption due to an increase in the conveying load.

[0042] On the other hand, in the recording device 1A of this embodiment shown in Fig. 7, the overlap length changes when the blade 93 comes into contact with the outer peripheral surface 5a and bends, and also when the first frame 91 moves relative to the second frame 92 along the normal direction of the outer peripheral surface 5a. Therefore, the relationship between the overlap length and the biasing force changes in two stages, as shown in Fig. 8. In detail, the overlap length changes when the overlap range is up to 0.5 mm as the blade 93 comes into contact with the outer peripheral surface 5a and bends, and when the overlap range is more than 0.5 mm, the overlap length changes when the first frame 91 moves relative to the second frame 92 along the normal direction of the outer peripheral surface 5a.

[0043] For this reason, in the recording apparatus 1A of this embodiment shown in Fig. 7, the effective range is set to a biasing force of 100N or more and 200N or less. In this way, even if the range of the biasing force is narrowed, the overlap range is large, ranging from 0.5mm to 6.0mm. Therefore, the recording apparatus 1A of this embodiment can suppress wiping omissions due to design tolerances and variations in components, and can suppress the occurrence of transport failures and the increase in power consumption due to an increase in the transport load.

[0044] Here, in the recording apparatus 1A of this embodiment, as described above, the elastic member that biases the first frame 91 against the second frame 92 is the spring 95. By configuring the elastic member in this way, it is possible to achieve a low-cost and simple configuration.

[0045] 5 and 6, the spring 95 in the recording device 1A of this embodiment has an attachment portion 95b that can be attached to the attachment portion 91a of the first frame 91, and an attachment portion 95a that can be attached to the attachment portion 92a of the second frame 92. By configuring the elastic member in this way, the elastic member can be attached to the first frame 91 and the second frame 92, and the second frame 92 that supports the first frame 91 movably along the normal direction of the outer circumferential surface 5a can be easily configured. However, the elastic member is not limited to being configured in this way. For example, the elastic member may be configured of a member other than the spring 95, such as a rubber member.

[0046] On the other hand, by configuring the elastic member as the spring 95, the initial load can be set to any value by the user. For example, the adhesive applied to the outer peripheral surface 5a of the conveyor belt 5 deteriorates and peels off over time. Depending on the deterioration of the conveyor belt 5, the user can maintain the performance of wiping off the cleaning liquid by attaching a spring 95 with a larger initial load than the spring 95 attached when the conveyor belt 5 was new. In addition, the user can arbitrarily select an adhesive to apply to the outer peripheral surface 5a of the conveyor belt 5, but the appropriate biasing force of the blade 93 against the outer peripheral surface 5a also changes depending on the type of adhesive used. As will be described later, the recording device 1A of this embodiment can maintain the performance of wiping off the cleaning liquid regardless of the type of adhesive because the type and number of the springs 95 can be freely selected.

[0047] Furthermore, in the recording device 1A of this embodiment, the attachment portions 91a and 92a are convex, the attachment portions 95a and 95b are annular, and the spring 95 can be easily attached to the first frame 91 and the second frame 92, and can also be easily attached to and detached from the first frame 91 and the second frame 92. For this reason, the recording device 1A of this embodiment is particularly easy to assemble.

[0048] As shown in FIG. 4, the recording device 1A of this embodiment has a plurality of first frames 91 arranged in the width direction B, and as shown in FIG. 4, FIG. 5, and FIG. 6, the recording device 1A of this embodiment can attach a plurality of springs 95, which are elastic members, to one first frame 91. With such a configuration, the recording device 1A of this embodiment can urge the blade 93 against the outer peripheral surface 5a with a suitable urging force, for example, by changing the number and type of elastic members attached to each first frame 91. Specifically, the springs 95 can be replaced with springs with a strong urging force, or some of the springs 95 can be left detached. Furthermore, it is also possible to change the urging force of the blade 93 against the outer peripheral surface 5a in the width direction B by replacing the springs 95 of the first frames 91 located at the ends in the width direction B with springs with a strong urging force, or by replacing the springs 95 of the first frames 91 located in the center in the width direction B with springs with a weak urging force.

[0049] 2, 3 and 4, in the recording apparatus 1A of this embodiment, a plurality of first frames 91 are connected to one second frame 92 via springs 95. With this configuration, the recording apparatus 1A of this embodiment makes it easier for the second frame 92 to support each of the first frames 91 movably along the normal direction of the outer peripheral surface 5a, improving the ability of the first frames 91 to follow the outer peripheral surface 5a. This improves the effect of the blade 93 wiping the outer peripheral surface 5a.

[0050] 5, 6, and 7, the first frame 91 is fixed to the second frame 92 by a plurality of screws 97. In detail, the screw shafts of the screws 97 fixed to the second frame 92 pass through the screw holes of the first frame 91, and the first frame 91 is sandwiched between the second frame 92 and the screw heads of the screws 97. Here, the screw holes of the first frame 91 are elongated holes that are long along the normal direction of the outer peripheral surface 5a, and are longer along the normal direction of the outer peripheral surface 5a than the screw shafts of the screws 97. Therefore, the first frame 91 is movable relative to the second frame 92 along the normal direction of the outer peripheral surface 5a.

[0051] [Example 2] Next, the recording apparatus 1B of the second embodiment will be described with reference to FIG. 11. Here, FIG. 11 is a diagram corresponding to FIG. 7 of the recording apparatus 1A of the first embodiment. In FIG. 11, components common to the first embodiment are indicated by the same reference numerals, and detailed description will be omitted. Here, the recording apparatus 1B of this embodiment has the same configuration as the recording apparatus 1A of the first embodiment, except for the configuration of the blade forming unit 90. Therefore, except for the parts described below, the recording apparatus 1B of this embodiment has the same characteristics as the recording apparatus 1A of the first embodiment.

[0052] 11, the recording device 1B of this embodiment is provided with a plastic washer 70, which is a sliding member, between the first frame 91 and the second frame 92. For this reason, in the recording device 1B of this embodiment, the first frame 91 moves more easily relative to the second frame 92. Note that the sliding member is not particularly limited as long as it allows the first frame 91 to move more easily relative to the second frame 92 when there is a sliding member than when there is no sliding member, and may be a plastic washer as in this embodiment, or a fluid such as grease.

[0053] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the invention as defined in the claims, and needless to say, these modifications are also included within the scope of the present invention.
