[0016] 1. First Embodiment

[0017] First, the structure of a recording device 10 that constitutes a work system 1 will be described. The recording device 10 is a printer that can perform recording on a medium M (e.g., cloth, paper).

[0018] In addition, in each of the drawings below, the direction along the X axis represents the width direction of the recording device 10. The direction along the Y axis represents the depth direction of the recording device 10. The direction along the Z axis represents the height direction of the recording device 10.

[0019] Figure 1 The structure of the recording device 10 that is disposed on a floor portion 2 of a factory as one example of a disposition site will be described. A discharge device 4 as one example of a discharge apparatus is disposed on the floor portion 2. In addition, the discharge device 4 can also be disposed on an unillustrated ceiling portion of the factory. The discharge device 4 is provided with an unillustrated discharge fan and is connected to a discharge duct 6 of the recording device 10. Discharge from the recording device 10 is recovered and purified by the discharge device 4 via the discharge duct 6 and is emitted to the outside of the factory from the discharge device 4.

[0020] The recording device 10 includes a main frame 12, a housing 14 (main body portion), a conveyance unit 16, a recording portion 20, a cleaning unit 24, a control unit 28, and a flow passage portion 30.

[0021] The main frame 12 is configured as a base portion for disposing each portion of the recording device 10. The housing 14 is an exterior member that covers each portion of the recording device 10. The main frame 12 and the housing 14 are members that have a magnetic body. The housing 14 accommodates the recording portion 20 and the like.

[0022] A housing cover 19 that is openable and closable is provided at the +Y direction end of the housing 14. The housing cover 19 is a part of the housing 14. The housing cover 19 is located above the conveyance belt 17 (rubber belt). The housing cover 19 extends in the direction along the X axis. The width dimension of the housing cover 19 in the direction along the X axis is slightly longer than the width dimension of the conveyance belt 17 in the direction along the X axis. The housing cover 19 is rotated about an axis provided in the direction along the X axis, between a closed state and an open state. In the case where the housing cover 19 is in the closed state, the housing cover 19 is in the direction along the Z axis when viewed in side view. In the case where the housing cover 19 is in the open state, the housing cover 19 is located at a position that is more upward than the horizontal direction when viewed in side view. A damper that is not shown is provided on the housing cover 19, and the housing cover 19 can be held in the open state.

[0023] In the recording processing of the recording device 10, the housing cover 19 is set to the closed state, and in the maintenance work of the conveyance belt 17 described later, the housing cover 19 is set to the open state.

[0024] The conveyance unit 16 includes a drive roller 16A, a driven roller 16B, a conveyance belt 17, and a take-up roller that is not shown. Also, the conveyance unit 16 is able to convey the medium M in the +Y direction, with movement of the conveyance belt 17 caused by rotation of the drive roller 16A. The drive roller 16A is disposed at the downstream in the conveyance direction, and the driven roller 16B is disposed at the upstream in the conveyance direction. Further, both the drive roller 16A and the driven roller 16B have a rotation axis in the direction along the X axis. The rotation of the drive roller 16A is controlled by the control unit 28.

[0025] The conveyance belt 17 is composed of a jointless belt in which both ends of a flat plate having elasticity are joined. Further, the conveyance belt 17 is wound around the outer peripheral surface of the drive roller 16A and the outer peripheral surface of the driven roller 16B, and is thereby able to move in a loop. An adhesive that is able to adhere the medium M is provided on the outer peripheral surface 17A of the conveyance belt 17. The medium M is supported on the conveyance belt 17 in a state of being adhered to the adhesive. The medium M is peeled from the adhesive and is recovered onto a take-up device that is not shown.

[0026] A flat portion in the outer peripheral surface 17A between the drive roller 16A and the driven roller 16B and in the +Z direction is a support surface 18 that supports the medium M.

[0027] Further, the conveyance belt 17 of the present embodiment has an exposed portion 90 in which a portion of the conveyance belt 17 is exposed with respect to the housing 14. Specifically, the conveyance belt 17 protrudes in the +Y direction with respect to the housing 14 (the housing cover 19 in the closed state). This protruding portion corresponds to the exposed portion 90. Since the conveyance belt 17 protrudes with respect to the housing 14, the fingers of a user are less likely to interfere with the housing 14 when the user performs a maintenance operation of the conveyance belt 17 described later, such as an operation of peeling or applying an adhesive to the conveyance belt 17, and thus the operability can be improved.

[0028] The recording section 20 performs recording on the conveyed medium M. Specifically, the recording section 20 includes a recording head 21 that ejects liquid (for example, ink) as droplets, and a carriage 22 that supports the recording head 21 and moves reciprocally in the direction along the X axis. The recording section 20 is opposed to the support surface 18 and is disposed above (in the +Z direction) the conveyance belt 17. The recording head 21 is capable of recording on the medium M by ejecting droplets with respect to the conveyed medium M while moving in the direction along the X axis.

[0029] The cleaning unit 24 is located downstream of the drive roller 16A in the direction in which the conveyance belt 1 moves around, and cleans the outer circumferential surface 17A.

[0030] The control unit 28 is configured to include a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a storage, and controls the operation of each portion of the recording device 10.

[0031] The flow passage section 30 is a portion of the inside of the housing 14 that includes the space 41 and functions as a flow passage that causes air to flow forcibly. Further, the flow passage section 30 has a blowing section 32 and a suction section 42.

[0032] The blowing section 32 is provided on the -Y direction side (upstream side) of the recording section 20. The blowing section 32 has the first fan 38, causes air to flow in via the flow inlet 15, and sends the air toward the support surface 18.

[0033] The suction section 42 is provided on the +Y direction side (downstream side) of the recording section 20, and suctions air that flows from the support surface 18. Specifically, the suction section 42 has a flow passage section 44 and a second fan 52. The flow passage section 44 has the first duct 56 and a second duct 76 that is disposed above the first duct 56. The second duct 76 is connected to the exhaust duct 6.

[0034] The second fan 52 is disposed inside the first duct 56. The second fan 52 draws air from the circulation section 44. Furthermore, the air drawn out by the second fan 52 is discharged from the exhaust duct 6 through the first duct 56 and the second duct 76.

[0035] A filter 78 is installed inside the second pipe 76. The filter 78 is capable of capturing foreign matter such as smoke mixed in with the air. The filter 78 can be made of non-woven fabric, glass wool, or rock wool.

[0036] Next, the maintenance work for conveyor belt 17 will be explained.

[0037] Maintenance of the conveyor belt 17 includes, for example, replacing the adhesive on the conveyor belt 17. Specifically, when the medium M is bonded to the conveyor belt 17 and recording processing is performed while the medium M is being transported, ink, thread ends, dust, etc., adhere to the adhesive applied to the conveyor belt 17. As a result, the adhesive strength gradually decreases, making it impossible for the medium M to be transported while being adequately bonded to the conveyor belt 17. In this case, the adhesive applied to the outer peripheral surface 17A of the conveyor belt 17 is removed, and a new adhesive is applied to form an adhesive layer on the conveyor belt 17. As a result, the adhesive strength for the medium M is restored. Furthermore, this maintenance work involving the application of adhesive is also performed on the new conveyor belt 17 when the recording device 10 is newly installed in the factory.

[0038] In the aforementioned maintenance work, the solvent or adhesive used to remove the adhesive from the conveyor belt 17 may contain volatile organic compounds (VOCs). In this case, there is a possibility that the vaporized VOCs may diffuse into the surrounding environment. Moreover, the VOCs that diffuse into the surrounding environment may have a chemical effect on the various mechanical components and electrical parts constituting the recording device 10, and as a result, there is a possibility that they may affect the operation of the recording device 10.

[0039] Therefore, in this embodiment, an operating system 1 is configured to suppress the diffusion of vaporized VOCs during the aforementioned maintenance operations.

[0040] The structure of operating system 1 will be described below.

[0041] like Figure 2 , Figure 3 as well as Figure 4 As shown, the operating system 1 includes a recording device 10, a cover 100, and a removal unit. The structure of the recording device 10 is as described above.

[0042] In addition, Figure 2 In the diagram, the recording device 10 is represented by a solid line, and the cover 100 is represented by a double-dotted line. Figure 3 as well asFigure 4 A portion of the recording device 10 is indicated by a two-dot chain line, and the cover 100 is indicated by a solid line.

[0043] The cover 100 is provided in the maintenance work of the conveyer belt 17. The cover 100 is a member that covers at least a portion of the exposed portion 90 of the conveyer belt 17 provided on the recording device 10, which is exposed from the housing 14. Further, the removal portion of the present embodiment is the second fan 52 (refer to Figure 1 ), and sucks the gas of the space covered by the cover 100. The sucked gas is discharged to the outside of the factory via the exhaust duct 6. Thereby, the gas, such as VOC, of the space covered by the cover 100 is removed. That is, the diffusion of the gasified VOC can be suppressed.

[0044] Further, the covering of at least a portion of the exposed portion 90 of the conveyer belt 17 by the cover 100 means that there is an area in which the exposed portion 90 of the conveyer belt 17 and the cover 100 overlap when the recording device 10 is viewed from above, viewed from the side Figure 3 ), or viewed from the front Figure 4 ). In the present embodiment, the entire exposed portion 90 of the conveyer belt 17 and the cover 100 overlap when the recording device 10 is viewed from above and viewed from the side. That is, the exposed portion 90 is covered by the cover 100 when the recording device 10 is viewed from above and viewed from the side. On the other hand, when the recording device 10 is viewed from the front, the opening 130 is provided on the cover 100, and the cover 100 does not overlap the conveyer belt 17 in the width direction and the height direction thereof via the opening 130. That is, the opening 130 is formed so that the user can directly view the conveyer belt 17 when the recording device 10 is viewed from the front. Thereby, the conveyer belt 17 can be directly contacted via the opening 130, and thus the maintenance work of the conveyer belt 17 becomes easy.

[0045] Further, the space covered by the cover 100 means the space that is closed by the cover 100 around the exposed portion 90 assuming that the opening 130 is closed.

[0046] The cover 100 of the present embodiment has a first cover 101 and a second cover 102.

[0047] The first cover 101 is disposed so that the portion of the conveyer belt 17 in the +Y direction, which protrudes (exposed portion 90), is substantially centered from the housing cover 19. The second cover 102 is disposed so that the portion of the housing 14 in the -Y direction is substantially centered from the housing cover 19.

[0048] The first cover 101 is provided in a state in which the housing cover 19 is set to the open state. Specifically, it is provided in a state in which it is lowered from the upper surface of the housing cover 19 in the open state to a position below the recording device 10. The lower end portion of the first cover 101 is in contact with the setting surface 2 to the extent. Thus, leakage of gas from the lower portion of the recording device 10 can be suppressed. In addition, the first cover 101 can be provided in a manner in which the portion in which the operation panel portion 29 is disposed is exposed.

[0049] In the present embodiment, a plurality of frames 110 are provided which are provided at intervals from each other. The frames 110 are formed of an antistatic material. In the present embodiment, two rod-shaped frames 110 are provided. Specifically, one frame 110 is provided between the housing cover 19 and the portion of the housing 14 in the +X direction of the conveyance belt 17. The other frame 110 is provided between the housing cover 19 and the portion of the housing 14 in the -X direction of the conveyance belt 17. These frames 110 support the housing cover 19. Thus, the open state of the housing cover 19 can be reliably maintained.

[0050] The +Y direction end portion of the housing cover 19 in the open state is located at a position slightly further in the +Y direction than the conveyance belt 17 and the main body frame 12. That is, the +Y direction end portion of the first cover 101 is provided in a state in which it is lowered to the vicinity of the +Y direction end portion of the conveyance belt 17. Thus, the first cover 101 can cover the periphery of the exposed portion 90 of the conveyance belt 17 with a minimum size. Therefore, the removal efficiency of gas in the space covered by the first cover 101 can be improved, and the ventilation efficiency can be improved.

[0051] Furthermore, since the area between the exposed portion 90 and the second fan 52 is made larger by setting the housing cover 19 to the open state compared to the case in which the housing cover 19 is in the closed state, the exhaust efficiency of gas in the space covered by the first cover 101 can be further improved.

[0052] The first cover 101 is formed of an antistatic material. Thus, the carrying of static electricity can be prevented, and discharge can be prevented. The first cover 101 can use, for example, cloth, vinyl, or the like. In particular, the first cover 101 is preferably a thin vinyl material having light transmittance. Thus, it becomes possible to visually confirm the conveyance belt 17 through the first cover 101, and the work efficiency can be improved.

[0053] The first cover 101 is attached in a manner that can be removed with respect to the recording device 10. The first cover 101 is fixed with respect to the casing 14 or the main frame 12 by at least one fixing portion 104. The fixing portion 104 is, for example, a thin sheet-shaped magnet that can be deformed freely. In the present embodiment, a plurality of fixing portions 104 (magnets) are provided at a plurality of places of the first cover 101, and are attracted to the casing 14 or the main frame 12 that has a magnetic body. Thereby, for example, displacement of the first cover 101 with respect to the casing 14 or the main frame 12 at the time of suction of the second fan 52 can be suppressed, and thus the space covered by the first cover 101 can be maintained. Further, the fixing portion 104 (magnet) can be easily removed from the casing 14 by a finger. Thereby, in a case where the maintenance work of the conveyance belt 17 is not performed, by removing the first cover 101 from the casing 14, for example, a case where a user contacts the exposed portion 90 to become an obstacle of the work of setting the medium M can be suppressed.

[0054] Further, the fixing portion 104 can use a face fastener or the like to fix the first cover 101 and the casing 14 or the main frame 12.

[0055] The second cover 102 is also attached in a manner that can be removed from the recording device 10, and is provided in a state of hanging from the upper portion of the casing 14 to the lower portion of the recording device 10 except for the exhaust duct 6. The second cover 102 is also fixed with respect to the casing 14 or the main frame 12 by the fixing portion 104 (for example, a magnet). In the present embodiment, an opening portion is provided at the +Y direction end portion of the casing 14, and a portion of the conveyance belt 17 is open from the casing 14. Therefore, by covering the portion including the -Y direction end portion of the recording device 10 by the second cover 102, diffusion of VOC emitted from the adhesive or the like of the conveyance belt 17 is suppressed. The second cover 102 also uses an antistatic material like the first cover 101.

[0056] The fixing portion 104 is fixed in a manner that a portion of the first cover 101 and a portion of the second cover 102 overlap. Thereby, the gap of the first cover 101 and the second cover 102 is eliminated, and leakage of VOC is suppressed.

[0057] Further, the cover 100 can be a one-piece molded member.

[0058] According to the present embodiment, by providing the cover 100 (the first cover 101, the second cover 102) that covers at least a part of the exposed portion 90 of the conveyance belt 17, it is possible to limit the range in which vaporized volatile organic compounds (VOC) generated from a release agent, an adhesive, or the like diffuse to the periphery of the recording device 10, for example, in a maintenance work of the conveyance belt 17. Also, by removing the gas of the space covered by the cover 100 using the second fan 52, it is possible to remove the vaporized VOC. Therefore, it is possible to suppress the chemical action on the recording device 10, thereby suppressing the influence on the operation or the like of the recording device 10.

[0059] In addition, the removal section in the work system 1 is not limited to the second fan 52. For example, the removal section can also be the exhaust device 4 provided in the factory. Further, the removal section can be either the air supply device or a porous material that absorbs or adsorbs the gas of the space covered by the cover 100.

[0060] Further, although the cover 100 is formed of an antistatic material in the present embodiment, it is not limited thereto. For example, it can be configured in a manner in which the cover 100 is erected on the plurality of frames 110 as an erecting member. In this case, the conductivity of the frame 110 is greater than that of the cover 100, and the frame 110 is directly or indirectly electrically connected to the recording device 10. In the case where the frame 110 is indirectly electrically connected to the recording device 10, the frame 110 is connected to the recording device 10 via an electrically conductive member such as an electric wire. The recording device 10 is grounded. Thereby, it is possible to make the potential of the cover 100 and the frame 110 substantially equal to the potential of the recording device 10. Therefore, it is possible to suppress the discharge caused by the potential difference between the potential of the frame 110 and the potential of the recording device 10.

[0061] Although a large opening 130 is provided at the +Y direction end portion of the first cover 101 in the present embodiment, it is not limited thereto. For example, a plurality of openings 130 can be formed, and the total area of the openings 130 can be reduced. Thereby, it is possible to increase the area covered by the first cover 101, thereby improving the gas suction efficiency of the space covered by the first cover 101.

[0062] Further, although only the opening 130 is provided at the +Y direction end portion of the first cover 101 in the present embodiment, in addition thereto, for example, a plurality of openings can be provided at the +X direction end portion of the first cover 101 or the -X direction end portion of the first cover 101, or the like. By being configured in this manner, it is possible to perform the maintenance work by a plurality of persons.

[0063] 2. Second Embodiment

[0064] Next, the second embodiment will be described. In addition, for the same structure as the first embodiment, the same reference signs are given, and the overlapping description will be omitted. Next, the second embodiment will be described. In addition, for the same structure as the first embodiment, the same reference signs are given, and the overlapping description will be omitted.

[0065] Although the first cover 101 is provided with the opening 130 and the conveyance belt 17 is exposed in the front view in the first embodiment, in the present embodiment, as shown in Figure 5 , the opening 130 of the first cover 101 is provided with a cover portion 140. The opening 130 as a whole is covered with the cover portion 140. Thereby, the exposed portion 90 of the conveyance belt 17 is covered with the first cover 101 in all directions. Thereby, diffusion of VOC to the outside of the first cover 101 can be suppressed. In addition, in Figure 5 , a part of the recording device 10 is indicated by a two-dot chain line, and the cover 100 is indicated by a solid line.

[0066] Further, the cover portion 140 is capable of being displaced to a position at which a space covered with the first cover 101 by the opening 130 communicates with an outside space of the first cover 101. Specifically, as shown in Figure 6A and Figure 6B , the cover portion 140 of the present embodiment is composed of a plurality of long rectangular long member 141 (141a, 141b). The cover portion 140 of the present embodiment is configured to be a curtain by the long member 141. The long member 141 (141a, 141b) is an elastic member, for example, is formed of a rubber member having light transmittance. The +Z direction end portion and the -Z direction end portion of the long member 141a are fixed to the first cover 101. The portion of the long member 141a other than the portion fixed to the first cover 101 is capable of being deformed freely. The long members 141a are arranged at a predetermined interval in the direction along the X axis. Further, the +Z direction end portion of the long member 141b is fixed to the +Z direction end portion of the adjacent long member 141a. Similarly, the -Z direction end portion of the long member 141b is fixed to the -Z direction end portion of the adjacent long member 141a. That is, the end portion of the long member 141a in the X direction and the end portion of the long member 141b in the X direction are arranged in a manner of overlapping each other. Thereby, the opening 130 is closed by the cover portion 140 in the front view. The portion of the long member 141b other than the fixed portion is capable of being deformed freely.

[0067] The long member 141 is formed of an antistatic material. Thereby, deformation (displacement) can be easily caused. Also, when a user's finger, wrist enters from the cover portion 140 toward the conveyance belt 17, the cover portion 140 is easily deformed, thereby connecting the inside space of the first cover 101 and the outside space. Also, the space covered by the first cover 101 can be easily accessed, and work can be performed. Further, when the finger, wrist is withdrawn from the cover portion 140, the shape of the long member 141 returns to the state before the finger, wrist entered, by the elasticity of the long member 141. Thereby, in a case where the user does not perform work, diffusion of VOC can be reduced by blocking the opening 130.

[0068] Further, the cover portion 140 can also be configured to be attachable and detachable with respect to the first cover 101. In this case, for example, it is also possible to perform suction by the second fan 52 in a state where the cover portion 140 is attached to the first cover 101 (a state where the opening 130 is closed), and after the VOC of the space covered by the first cover 101 is removed, the cover portion 140 is detached and maintenance work is performed, for a predetermined period.

[0069] Further, although the cover portion 140 is configured by the long member 141 in the present embodiment, it is not limited thereto. For example, the cover portion 140 can also be formed by a sheet rubber member, and fixed to the first cover 101 by a wire fastener, a face fastener, or the like. Even if it is configured as such, since the cover portion 140 can be displaced, the same effects as described above can be obtained.

[0070] 3. Third Embodiment

[0071] Next, the third embodiment will be described. For the same structure as the first embodiment, the same reference numerals are assigned, and overlapping description will be omitted. Also, in the Figure 7 In the drawing, the recording device 10 is indicated by a two-dot chain line, and the cover 100A is indicated by a solid line.

[0072] The cover 100A of the present embodiment has a first cover 101A and a second cover 102A. The cover 100A (the first cover 101A, the second cover 102A) includes a contact portion 105 which contacts the setting surface 2 on which the recording device 10 is set. As Figure 7As shown, the contact portion 105 has a contact surface that extends from the lower hem of the cover 100A towards the mounting surface 2 and contacts the mounting surface 2. The contact portion 105 is disposed around the entire periphery of the cover 100A. Furthermore, a pressing portion 150 is provided to press the contact portion 105 against the mounting surface 2. The pressing portion 150 is a weight such as a chain. The pressing portion 150 is arranged to span the entire contact portion 105 (the entire circumference of the recording device 10). This improves the tightness of the seal between the mounting surface 2 and the cover 100A. Therefore, the airtightness of the space covered by the cover 100A can be improved, thereby reducing the diffusion of VOCs from the gaps in the lower part of the cover 100A. In addition, the pressing portion 150 may also be a mechanism that applies air pressure to the contact portion 105. Furthermore, the other structures of the first cover 101A and the second cover 102A are the same as those in the first embodiment.

[0073] 4. Fourth Implementation Method

[0074] Next, the fourth embodiment will be described. Furthermore, structures identical to those in the first embodiment will be labeled with the same symbols, and repeated descriptions will be omitted. Additionally, in Figure 8 In the diagram, a portion of the recording device 10 is represented by a double-dotted line, and the cover 100 is represented by a solid line.

[0075] like Figure 8 As shown, the operating system 1A of this embodiment is provided with an external air intake 160, which draws external air into the space covered by the first cover 101.

[0076] The outside air suction portion 160 has a communication portion 161 and a blower portion 162. The communication portion 161 communicates a space covered by the first cover 101 with an outside space of the first cover 101. The blower portion 162 blows air into the space covered by the first cover 101 via the communication portion 161. The communication portion 161 is a pipe and is provided so as to penetrate the first cover 101. The blower portion 162 is a fan. The blower portion 162 is supplied with electric power, for example, from a commercial power source. The blower portion 162 can be disposed in the space covered by the first cover 101 or outside the first cover 101. The outside air suction portion 160 is disposed, for example, above a user who performs a maintenance work. By driving the blower portion 162, outside air flows into the space covered by the first cover 101 via the communication portion 161. Thus, it is possible to suppress a case where VOCs remain in the space covered by the first cover 101, and it is possible to reduce the concentration of VOCs in a shorter time than in a case where the outside air suction portion 160 is not provided. Thus, it is possible to further suppress a case where the action of the recording device 10 is affected. In addition, the power source of the blower portion 162 can be common to the power source of the recording device 10. Specifically, the blower portion 162 is electrically connected to the recording device 10 via a cable, and the recording device 10 is connected to the commercial power source. Thus, electric power is supplied to the blower portion 162 via the recording device 10. Further, the power source of the blower portion 162 can be a storage battery.

[0077] 5. Fifth Embodiment

[0078] Next, the fifth embodiment will be described. For the same structure as the first embodiment, the same reference signs are used, and overlapping descriptions will be omitted.

[0079] Although the work system 1 is configured of the recording device 10, the cover 100, and the removal portion in the first embodiment, the entire work system 1 can be configured as the recording device 10.

[0080] That is, the recording device 10 can have a conveyance belt 17 provided with an adhesive capable of adhering a medium M and capable of conveying the medium M, a housing 14 in which a recording portion 20 capable of performing recording on the medium M is accommodated, a cover 100 that covers at least a part of an exposed portion 90 of the conveyance belt 17 exposed from the housing 14, and a removal portion (for example, a second fan 52) capable of removing gas in a space covered by the cover 100. Even if configured as such, the same effects as described above can be obtained.
