(2) Operating State of Device 10 Next, the operating state of the device 10 will be described.

As shown in FIGS. 1 and 3, a web W is arranged around the outer circumference of the cylindrical shell 20 . When the driving device 36 rotates together with the running speed of the web W, the shaft 18 is rotatably supported by the first bearings 28 and 68 and rotates. In this case, since the first bearings 28, 68 are bearings with an alignment function, they are less likely to be affected by the mounting orientation of the left and right support members 14, 16, so the shaft 18 can rotate smoothly.

As shaft 18 rotates, it is rotated by second bearing 56 in shell 20 . When the web W rotates at a constant traveling speed, the shell 20 rotates along with it, and the shaft 18 also rotates along with the traveling speed, so the web W can be guided smoothly.

(3) Dustproof Structure of Device 10 Next, the dustproof structure of the device 10 will be described. When the web W travels and the shell 20 and shaft 18 rotate as described above, dust is generated from the first bearings 28, 68 and the second bearings 52, 56. As shown in FIG. As shown in FIGS. 1 and 2, when dust is generated, the left side flows into the first left dust-proof space 32 and the right side flows into the first right dust-proof space 72 . As shown in FIGS. 1 and 5, it does not come out of the first left dustproof cover 30 and the first right dustproof cover 70 and does not adhere to the web W on the outer periphery of the shell 20 .

As shown in FIG. 1, when the suction device 78 is driven, dust inside the first left dust-proof space 32 is sucked through the main suction pipe 76, the vertical left suction passage 46, the horizontal left suction passage 44, and the suction passage 42, Completely dustproof. Further, as shown in FIGS. 1 and 2, the lateral left suction passage 44 also sucks the air in the second dustproof space 40, so dust generated by the coupling device 34 and the driving device 36 is also sucked, and the second dustproof cover It does not scatter from 38 to the outside. Also on the right side, the dust inside the first right dust-proof space 72 is sucked from the main suction pipe 76 through the vertical right suction passage 86 and the horizontal right suction passage 84, so that dust prevention can be completed.

(4) Effect According to the present embodiment, dust generated from the first bearings 28, 68 and the second bearings 52, 56 is removed by the first left dustproof cover 30 and the first right dustproof cover 70. , and stays inside the first right dust-proof space 72 and does not scatter outside, so that it does not adhere to the web W.

In addition, since the dust inside the first left dust-proof space 32 and the first right dust-proof space 72 is sucked by the suction device 78, the dust can be completely removed.

A slight gap 54 is formed between the shell 20 and the first left dustproof cover 30, and a small gap 74 is also formed between the right end of the shell 20 and the first right dustproof cover 70. , the shell 20 can rotate smoothly. Also, since the suction device 78 sucks the dust, the dust does not scatter from the gaps 54 and 74 .

(5) Modification In the above embodiment, the dust in the first left dust-proof space 32 and the first right dust-proof space 72 is sucked by the single suction device 78, but separate suction devices on the left and right sides may be used.

In the above embodiment, the suction passage 42 and the suction passage 82 are provided inside the left attachment portion 24 and the right attachment portion 64, and suction is performed through the insides of the left leg portion 22 and the right leg portion 62. A first suction port may be opened in each of the left dustproof cover 30 and the first right dustproof cover 70 , a suction pipe may be connected to each of the first suction ports, and the suction device 78 may suction. Similarly, in the second dust-proof space 40 , the second dust-proof cover 38 may be provided with a second suction port, a suction pipe may be directly connected to the second suction port, and the suction device 78 may perform suction.

Also, in the above embodiment, the first bearings 28, 68 are bearings with an alignment function, but they may be ordinary bearings without an alignment function.

In addition, although the suction device 78 is provided in the above-described embodiment, the dustproof effect can be achieved by simply providing the first left dust-proof cover 30, the second dust-proof cover 38, and the first right dust-proof cover 70 without providing the suction device 78. .

Also, in the above embodiment, the first left dustproof cover is attached to the left attachment portion 24, but instead of this, the first left dustproof cover 30 is attached to the left end portion of the shell 20, and the first left dustproof cover 30 and the left attachment are attached. A slight gap 54 may be provided between the portion 24 and the portion 24 . The same is true for the right side of shell 20 .

While one embodiment of the invention has been described above, this embodiment is provided by way of example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.
