DETAILED DESCRIPTION OF THE INVENTION

[0007] First, the configuration of the movable compressor box 1000 will be described with reference to FIGS.

[0008] As shown in FIG. 1, the movable compressor box 1000 includes an air compressor 100, a housing 200 that houses the air compressor 100, and casters 300 attached to the side surfaces 210 of the housing 200.

[0009] The air compressor 100 includes a compressor 110, a motor 120, a filter 130, a suction port 140, a discharge port 150, a first pipe 160, a second pipe 170, and a control unit 180.

[0010] The compressor 110, also called a blower, compresses the air that has passed through the filter 130 and discharges the compressed air from an outlet 150. The motor 120 is connected to the compressor 110 and drives the compressor 110. The motor 120 is disposed at the bottom of the housing 200 together with the compressor 110.

[0011] The filter 130 removes dirt, dust, and other particles from the air. The filter 130 is connected to an intake port 140 provided on a side surface 210 of the housing 200. The filter 130 is connected to the compressor 110 via a first pipe 160. The air sucked in from the intake port 140 passes through the filter 130 and is introduced into the first pipe 160.

[0012] The exhaust port 150 is provided on a side surface 210 of the housing 200. The exhaust port 150 is connected to the compressor 110 via a second pipe 170. The exhaust port 150 discharges the air compressed by the compressor 110. The second pipe 170 guides the air from the compressor 110 to the exhaust port 150.

[0013] The control unit 180 controls the driving of the motor 120. The control unit 180 is configured with an inverter, or a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like.

[0014] Such a movable compressor box 1000 is used, for example, in a sheet manufacturing apparatus that produces new paper by dry-type defibrating and fiberizing waste paper, and then pressurizing, heating, and cutting the paper. Specifically, the compressed air discharged from the outlet 150 is used, for example, in the sheet manufacturing apparatus, to blow compressed air from the direction opposite to the suction direction onto a filter that has sucked in the removed fibers, thereby blowing off the fibers adhering to the filter.

[0015] The housing 200 accommodates the above-mentioned compressor 110, motor 120, filter 130, first pipe 160, second pipe 170, and control unit 180. The housing 200 has, for example, a rectangular parallelepiped shape.

[0016] As described above, the caster 300 is attached to the side surface 210 of the housing 200. As shown in Fig. 2, the caster 300 includes a roller 310, a mounting plate 320 for attaching the roller 310 to the side surface 210 of the housing 200, and a connecting portion 330 for connecting the mounting plate 320 and the roller 310.

[0017] The mounting plate 320 is provided with mounting holes 350 for fixing the casters 300 with bolts 340. The mounting holes 350 are formed in an elliptical shape that is long in the vertical direction so that the position of the rollers 310 can be moved in the vertical direction.

[0018] The mounting plate 320 is provided with four of the above-described oval mounting holes 350. The casters 300 are fixed to the side surfaces 210 of the housing 200 with bolts 340 via the mounting holes 350. In this embodiment, the casters 300 are attached to the side surfaces 210 using four bolts 340. The combination of the mounting holes 350 and the bolts 340 is referred to as an adjuster 360.

[0019] 1 and 2, vibration-isolating legs 400 are attached to the bottom surface 220 of the housing 200. The vibration-isolating legs 400 are provided to fix the movable compressor box 1000 to the installation surface 510. The vibration-isolating legs 400 are also provided to prevent large vibrations generated by the air compressor 100 from being transmitted to the installation surface 510.

[0020] In this embodiment, six vibration-isolating legs 400 are attached to the bottom surface 220 of the housing 200. The six vibration-isolating legs 400 are arranged on the bottom surface 220 of the housing 200 at approximately equal intervals.

[0021] It is preferable that the height of the bottom 401 of the vibration-isolating leg 400 is the same as the height of the bottom 311 of the roller 310. In other words, the bottom 401 of the vibration-isolating leg 400 and the bottom 311 of the roller 310 are in contact with the installation surface 510. A preferred method of adjusting the position is to first install the movable compressor box 1000, then adjust the adjuster 360 to align the height of the roller 310, in other words, align the bottom 401 of the vibration-isolating leg 400 and the bottom 311 of the roller 310, and then fix them with the bolt 340.

[0022] Next, a maintenance method for the movable compressor box 1000 will be described with reference to FIG.

[0023] The movable compressor box 1000 is disposed, for example, in a gap in the device main body 500 (see FIG. 1). As shown in FIG. 3, when performing maintenance on the movable compressor box 1000, the movable compressor box 1000 is lifted and pulled out, for example, to the right in FIG. 3.

[0024] Specifically, when the movable compressor box 1000 is lifted obliquely in the pull-out direction, the vibration-isolating legs 400 arranged on the bottom surface 220 of the housing 200 rise above the installation surface 510. As a result, the only part of the movable compressor box 1000 that comes into contact with the installation surface 510 is the rollers 310. Therefore, the movable compressor box 1000 can be easily pulled out to the right in FIG. 3 .

[0025] 4, in the conventional movable compressor box 1000A, casters 300A are attached to the bottom surface 220 of the housing 200. Therefore, there is no gap in the height direction in the gap of the device main body 500, and when pulling out the movable compressor box 1000A, it comes into contact with the device main body 500, making it difficult to pull out, i.e., difficult to perform maintenance.

[0026] However, in the movable compressor box 1000 of this embodiment, the casters 300 are attached to the side surfaces 210 of the housing 200, and the height of the casters 300 is further adjusted to an appropriate position by the adjusters 360. Therefore, when the movable compressor box 1000 is placed in a gap in the device main body 500, a gap can be secured in the height direction. As a result, when the movable compressor box 1000 is pulled out for maintenance, contact with the device main body 500 is reduced, and the box can be easily pulled out.

[0027] Furthermore, a conventional movable compressor box 1000A requires at least four casters 300A for installation. Furthermore, a fixing mechanism is required to prevent the casters 300A from moving. However, the movable compressor box 1000 of this embodiment is provided with vibration-isolating legs 400, so only two casters 300 are required. Furthermore, since the box can be fixed in place using the vibration-isolating legs 400, no fixing mechanism is required. This reduces costs.

[0028] As described above, the movable compressor box 1000 of this embodiment includes the air compressor 100, the housing 200 that houses the air compressor 100, and the casters 300 for movement that are attached to the side surfaces 210 of the housing 200. With this configuration, the height of the housing 200 can be reduced because the casters 300 for movement are attached to the side surfaces 210 of the housing 200. This makes it possible to tilt the housing 200, and the casters 300 can be used to move the housing 200. Therefore, after placing the movable compressor box 1000 in a gap in the device main body 500 and using it, it can be easily pulled out from a narrow gap, making maintenance easier.

[0029] Furthermore, since the height is kept low, the movable compressor box 1000 can be installed even in a narrow space such as the bottom of a sheet manufacturing apparatus.

[0030] Furthermore, the movable compressor box 1000 of this embodiment preferably includes vibration-isolating legs 400 attached to the bottom surface 220 of the housing 200. With this configuration, since the vibration-isolating legs 400 are provided on the bottom surface 220, when the movable compressor box 1000 is placed in a gap in the device main body 500 for use, it can be firmly installed and fixed so that it does not move from its installed location. Furthermore, since the vibration-isolating legs 400 are provided, even if large vibrations are generated from the air compressor 100, it is possible to suppress the vibrations transmitted to the installation surface 510, thereby suppressing vibration of the installation surface 510. In other words, the noise reduction effect can be improved.

[0031] Furthermore, the movable compressor box 1000 of this embodiment preferably includes adjusters 360 that can change the position of the casters 300. With this configuration, the adjusters 360 make it possible to adjust the relative positions of the casters 300 and the installation surface 510. Specifically, when the movable compressor box 1000 is placed in a gap in the apparatus main body 500, the adjusters 360 do not interfere more than necessary with the installation surface 510, preventing the vibration-proof legs 400 from floating. When the box is pulled out for maintenance, the casters 300 can be adjusted so that only they are in contact with the installation surface 510 when moving.

[0032] A modification of the above embodiment will now be described.

[0033] As described above, in addition to arranging the intake port 140 and the exhaust port 150 on the side surface 210 of the housing 200, a cooling fan for cooling the air compressor 100 may also be arranged. [Explanation of symbols]
