空気流出面に密着するようになっていた。However, in this conventional filter device, the distance between the guide roll and the air outflow surface of the device main body is predetermined according to the thickness of the filter medium used. By passing the filter medium between the air outflow surface and the guide roll, the filter medium comes into close contact with the air outflow surface of the apparatus main body.

を要していた。For this reason, when the thickness of the filter medium is smaller than a predetermined thickness, a gap is formed between the filter medium and the air outflow surface of the apparatus main body, and dust leaks from the gap.
When the thickness of the filter medium is larger than the predetermined thickness, the filter medium is drawn into the space between the air outflow surface of the apparatus main body and the guide roll by the traction force at the time of winding, and is narrowed down to the predetermined thickness. For this reason, the frictional damage of the filter medium is large, and a heavy load is applied to a driving source for winding the filter medium. Furthermore, when the filter medium is thicker than expected, it must pass through the space between the air outlet surface of the apparatus body and the guide roll while compressing the filter medium, and it takes much time and effort to install the filter medium. I needed it.

Air flow to both sides in the device body 1
Two filter media shafts 3a, 3b are arranged at a distance from the outlet surface 2 to the air inflow surface 5 side, and a guide roll 4 is provided between each of the filter media shafts 3a, 3b and the air outflow surface 2 of the apparatus body 1.
a and 4b are arranged. The filter medium X before dust collection is wound around the one filter medium shaft 3a, and is unwound from the filter medium shaft 3a.
It is wound around another filter medium shaft 3b via guide rolls 4a and 4b. During this time, the filter medium X located on the air outflow surface 2 of the device main body 1 has the air inflow surface 5 of the device main body 1 attached thereto.

When the filter medium is wound up, a certain amount of difference is generated between the pressure at the time of air inflow and the pressure at the time of outflow of the apparatus body 1 due to dust collection of the filter medium X. There is a method of winding up the filter medium X only for the length of the air outflow surface 2 of the above, or a method of winding up the filter medium X at every elapse of a predetermined time by a timer method. Which method is adopted? May be appropriately determined in consideration of the size of the apparatus, the installation place, the use state, and the like.

In order to cope with the fluctuation of the thickness of the filter medium, in the filter device of the present invention, the guide roll moves between each of the filter medium shafts and the air outflow surface of the apparatus main body in accordance with the thickness of the filter medium. It is provided in. That is, when the filter medium is wound, when the thickness of the filter medium is thin, the guide roll moves toward the air outflow side between each of the filter medium shafts and the air outflow surface of the apparatus body,
When the thickness of the filter medium is large, the guide roll moves to the filter medium shaft side so that the filter medium can be held in close contact with the air outflow surface of the apparatus main body.

If it is assumed that they are arranged so that ゜, a traction force F of a magnitude corresponding to the thickness of the filter medium X acts on the unwinding side guide roll 4 a in a direction parallel to the air outflow surface 2. Similarly, a traction force F of a magnitude corresponding to the thickness of the filter medium X acts on the guide roll 4b on the winding side in a direction parallel to the winding direction. As shown in FIG. 5, when the traction force F acting on the guide roll 4b is decomposed, it is divided into a force F1 acting on the air outflow surface 2 side and a force F2 acting on the filter medium shaft 3b side. The guide roll 4b is moved toward the air outflow surface 2 by the force F1 among these forces. On the other hand, as shown in FIG. 6, when the traction force F acting on the guide roll 4a is decomposed, a force F3 acting on the air outflow surface 2 side and a force F acting on the filter medium shaft 3a side are obtained.
It is divided into four. The guide roll 4a is moved to the air outflow surface 2 side by the force F3 among them.
In practice, resistance acts on the force to move the filter medium, so that the traction force F acting on the guide roll 4b increases as shown by the dotted line in FIG. 5, and accordingly, F1 also increases. On the other hand, the traction force F acting on the guide roll 4a decreases as shown by the dotted line in FIG. 6, and F3 also decreases.

る。As described above, in this filter device, the air outlet surface 2 of the device main body 1 is disposed so as to have a substantially C-shape, and the air outlet surface 2 of each of the long holes 7 is connected to the air outlet surface 2. The ends of the guide rolls 4a, 4b are loosely inserted into the elongated holes 7, 7 whose angle is in the range of 15 to 50 °, and the guide rolls 4a, 4b exert a traction force when the filter medium X is wound. F
Is moved to the air outflow surface 2 side of the apparatus main body 1 under the action of Thus, the filter medium X is always kept in close contact with the air outflow surface 2 of the apparatus main body regardless of the thickness. The shape of the long holes 7 is not limited to a linear hole, but may be an arm-shaped bend as shown in FIGS. 9 and 10. In this case, the guide rolls 4a, 4b The wear damage in each of the long holes 7, 7 is suppressed, and smoother movement becomes possible.

The force (F1, F3) for moving the guide rolls 4a, 4b to the air outflow surface 2 side of the apparatus main body 1 has an angle of 15 as described above.
In each case, the size becomes smaller than that in the case of ゜, and accordingly, the force for bringing the filter medium X into close contact with the air outflow surface 2 of the apparatus main body 1 also becomes smaller. In such a case, urging the guide rolls 4a and 4b toward the air outflow surface 2 is extremely effective.

A spring member 8 is attached to the rotating shafts 6a, 6b of the guide rolls 4a, 4b, and the guide rolls 4a, 4b are urged toward the air outflow surface 2 of the apparatus main body 1 by the spring force of the spring member 8. For this reason, when the thickness of the filter medium X is large at the time of winding the filter medium, the guide rolls 4a and 4b resist the urging force to the air outflow surface 2 side of the apparatus body 1 due to the traction force at the time of winding. 7, 7 are moved toward the respective filter medium shafts 3a, 3b. When the thickness of the filter medium X is small, the guide rolls 4a,
4b is moved to the air outflow surface 2 side of the apparatus main body 1 against the traction force at the time of winding by the urging force of the apparatus main body 1 toward the air outflow surface 2 side. Thus, the slot 7,

Is performed, for example, a detecting means for detecting the thickness of the filter medium X, a driving means for driving the guide rolls 4a and 4b back and forth with respect to the air outflow surface 2 of the apparatus main body 1, and An adjusting device comprising control means for driving the driving means in response to the signal is used, whereby the positions of the guide rolls 4a and 4b are changed in accordance with the thickness of the filter medium X, so that the filter medium X is placed on the air outflow surface of the apparatus main body 1. 2 may be adjusted so as to be always in close contact. Further, the position of the guide roll may be manually changed without using a spring member or an adjusting device.
