Description

[Detailed Description of the Invention] This invention relates to a furnace material sagging prevention device for a furnace material winding type dust collector and an actuating device for a furnace material holder that operates a furnace material winding end switch.

In the conventional door material holding device, when the furnace material sags due to its own weight, or when the furnace material is wound up to a predetermined length and feeding is stopped, the rolled furnace material is removed. In order to prevent the furnace material from being sent out excessively due to inertia, a furnace material holder is installed that constantly presses against the furnace material using spring pressure or its own weight to suppress sagging of the furnace material and inertial force during winding.

This furnace material holder can freely rotate in the radial direction of the furnace material, and as the furnace material is wound up and the roll diameter becomes smaller, the furnace material holder also responds, and when the furnace material runs out, the furnace material holder responds. Contact the shaft.

Further, the winding end switch is configured to utilize this movement to operate a winding end switch that detects that the furnace material has run out.

However, with conventional models, spring pressure is used to press the furnace material from the anti-gravity direction, and in those that press the furnace material in the direction of gravity, the furnace material holder is lifted upward when replacing the furnace material. However, fresh furnace material must be installed.

Therefore, a locking member is provided to fix the furnace material holder in the lifted state, but in the former case, the spring of the furnace material holder may become deformed, or in the latter case, after the furnace material is replaced, the locking member of the furnace material holder may be removed. If you forget, the furnace material may sag, or the furnace material winding end switch may not operate even though there is no furnace material left.

This invention eliminates the above drawbacks, has a simple structure,
Moreover, it is an object of the present invention to provide a device that reliably operates a furnace material presser.

An embodiment of this invention will be described below.

In the figure, 1 is an upper furnace material storage box, 2 is a lower furnace material storage box, and 3 is rotatably stored via a door material shaft 3a.

4 is attached to the opening 1a of the upper furnace material storage box 1 by a hinge 4a,
The upper door is attached to be openable and closable, and has a protrusion 4b that protrudes into the upper furnace material storage box 1.

A furnace material holder 5 is rotatably mounted on a bearing 5a in the upper furnace material storage box 1, and presses against the furnace material 3 when passing;
6 is an end-of-roll switch having an actuator 6a which is activated by the furnace material presser 5 to detect the end of winding of the furnace material when the furnace material 3 runs out; 7 is the upper guide roll; 8 is the lower guide roll; 9 is the contaminated furnace material. 10 is a lower door provided at the opening of the lower furnace material storage box 2, 11 is a drive device for the furnace material winding shaft 9, and 12 is a winding shaft for both storage boxes 1 so as to cross the air flow passage surface.
, a curtain rod that guides the furnace material 3 installed between the two;
Reference numeral 13 denotes a locking member having a substantially U-shaped cross section, and includes a lower side 13a that supports the free end side of the furnace material presser 5 at that position when the furnace material presser 5 is lifted upward when replacing the furnace material, and a locking member that is shorter than this lower side 13a. an upper side 13b, whose negative end is rotatably attached to the upper side of the upper furnace material storage box 1 via a spacer 14 with a screw 15 and a nut 16, and upper and lower sides 13a, 13b. It consists of a connecting side 13c that connects.

In such a configuration, when the furnace material 3 becomes contaminated by filtering dust-containing air, the winding shaft 9 is driven, and the contaminated part of the furnace material 3 is wound up on the winding shaft 8, and the fresh part is taken up. is sent out to the airflow passing surface.

By repeating this operation, the diameter of the roll of the furnace material 3 in the upper furnace material storage box 1 becomes smaller, and accordingly the furnace material presser 5 moves from the state of FIG. Press the actuator 6a of the switch 6 to stop the furnace material winding operation.

At this point, the furnace material will be replaced. At this time, first open the upper door 4, then rotate the furnace material holder 5 to the state shown in Fig. 2, and rotate the locking member 13 as shown in Fig. 3. Then, the furnace material presser 5 is locked to the lower side 13a of the locking member 13, and the furnace material presser 5 is locked to the lower side 13a of the locking member 13.
The furnace material 3 can be installed in the upper storage box 1 without getting in the way.

When the upper door 4 is closed, the protrusion 4b provided on the upper door 4 pushes the free end side of the locking member 13, as shown in FIG. The locking member 13 is rotated, and as a result, the furnace material presser 5 is released from the locking member 13, presses the furnace material 3, and enters the state shown in FIG. 2A.

As mentioned above, this invention has a simple structure, and by closing the door, the furnace material holder can be set in the normal position by its own weight, which eliminates the problem of forgetting to set the furnace material holder or spring deformation. etc. can be prevented.
