[0011]

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described with reference to the accompanying drawings, which show an embodiment of the invention. FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a side view thereof.

A brush roll (1) arranged above the metal strip horizontal pass line (a), (2)
Indicates a roll chock attached to the brush roll (1). The roll chock (2) has a separate structure from the following pressure-reducing head (4), which is a chock support system. A trolley (3) arranged above the pass line (a) is attached to the roll chock (2). The trolley (3) is of a type capable of moving in the axial direction of the brush roll (1), that is, in the direction transverse to the pass line (a).

[0013] (4) is a pressing head for pressing down the roll chock (2) of the brush roll (1). In the illustrated embodiment, the pressing head (4) is located above the trolley (3). (3) Under contact with the top surface,
The roll chock (2) is lowered through the trolley (3). The press-down head (4) is of a vertical drive type by an elevating mechanism (5) driven by a mechanical force such as an electric motor (not shown). In the illustrated embodiment, the lifting mechanism (5) has the same configuration as the screw jack facing downward, and the rod (5
a) The pressing head (4) is connected to the tip. The rod (5a) penetrates a frame (10) described later so as to be vertically movable. As the lifting mechanism (5), a gear-type transmission system (5b) from a driving device such as an electric motor can be advantageously applied.

Rails (7) and (7) are arranged facing the lower surfaces of the wheels (6) and (6) of the trolley (3).
The rails (7) (7) extend along the transverse direction to the pass line (a) at least over a range corresponding to the mounting of the trolley (3). The rails (7) and (7) are connected to a pneumatic cylinder and plunger device (9) (9) arranged on the frame (8) of the brush roll machine (A) in parallel with the pressing head (4). It is attached to the frame (10). The frame (10) is of a type capable of moving up and down. The frame (10) having a frame shape surrounding the trolley (3) on the upper side and the left and right sides can be advantageously applied. The frame (10) is slidingly fitted to a groove-shaped guide frame (11) extending vertically at a fixed position.

As is apparent from the above, the restraint in the vertical direction of the roll chock (2) of the brush roll (1) on the upper side of the pass line (a) is controlled by the pressing head (4).
And a pneumatic cylinder and plunger device (9) (9). Specifically, the rail (7) on the frame (10)
With the trolley (3) of the roll chock (2) placed on (7), the brush roll (1) is previously supported on the pneumatic cylinder / plunger device (9) (9) so that the device (9) (9) ) Is pressurized to a certain pressure, and while the internal pressure is maintained, the roll chock (2) is reduced by the reduction head (4), thereby restraining the roll chock (2) in the vertical direction. As the pressure of the roll chock (2) goes down, the pneumatic cylinder / plunger devices (9) (9) release internal air so as to keep the internal pressure constant.

In the restraining specification (also referred to as a pressing down specification), the transmission system (5b) of the lifting / lowering mechanism (5) of the pressing down head (4) is
In the case of a gear type which is easily available, is economical and is suitable for detecting the degree of reduction of the brush roll (1) because of its reliable operation, a pass line (a) of the roll chock (2) described later is used. And (3) canceling the backlash of the gear type transmission system with the internal pressure of the pneumatic cylinder / plunger device (9) under the condition of releasing the constraint in the along direction. This backlash elimination is effective during the entire stroke from the start of the reduction of the roll chock (2) by the reduction head (4) to the end of the reduction of the roll chock (2). Accordingly, during the entire stroke, there is no play in the downward movement of the brush roll (1) with the roll chock (2).

The pass line (a) of the roll chock (2)
The pneumatic cylinder / plunger device (9) while raising the rolling head (4) from the roll chocking (2) rolling position in a state where the restraint in the along direction is released.
When (9) is pressurized to keep the internal pressure constant, the frame (10) with the rails (7) and (7) is rolled with the trolley (3) on the roll chock (2) by the internal pressure.
After the plunger of the pneumatic cylinder and plunger device (9) goes up to the rising limit, the pressing head (4) continues to go up further and the frame is moved up together with the brush roll (1). (10) Move away from the trolley (3) above.

In this way, when the roll chock (2) is completely released from the reduction by the reduction head (4), an appropriate receiving device, for example, a receiving device using a rail on which the trolley (3) can be transferred, is arranged in a fixed position. And a brush with a roll chock (2) out of the brush roll machine (A) system under the guidance by the rails (7) and (7) on the frame (10) and the movement by the trolley (3) mounted on the rail. The roll (1) can be carried out in a short time.

As is apparent from the above description, when the reduction of the roll chock (2) by the reduction head (4) is released, the frame (10) connected to the pneumatic cylinder and plunger device (9) (9). The trolley (3) of the roll chock (2) is on the upper rails (7) (7). For this reason, the roll chock (2) is released from rolling down, that is, the brush roll (1) can be carried out of the system.

Pneumatic cylinder / plunger device (9)
(9) is arranged in parallel with the pressing head (4),
It has a function of lifting the roll chock (2) of the brush roll (1) above the pass line (a) above the pass line (a). Therefore, unlike the related art, there is no need for a push-up device below the roll chocks of the brush roll, which restrains the brush roll from descending. The push-up device is also provided below the pass line (a) so as to face the upper brush roll (1). When the brush roll [or backup roll] (1 ') is arranged, the lower roll (1') of the lower roll (1 ') extends in the same direction as the rails (7) and (7) over a similar range. Under the application of (12), it is possible to carry out the system in a short time. The roll chock (2 ') of the lower roll (1') is of a trolley type having wheels (13) (13) facing above the rails (12) (12). The lower roll (1 ') with the roll chock (2') is pushed up by the lifting head (15) of the lifting / lowering function (14) arranged below the roll chock (2 '). Can be The lifting head (1) is moved by the lifting mechanism (14).
5), the wheels (13) and (13) of the roll chock (2 ') are placed on the rails (12) and (12).

In the embodiment shown in the drawing, the roll chocks (2) of the upper brush roll (1) are fixed to the fixed frame (16) and the tip of the pneumatic cylinder / plunger device (17) in the direction along the pass line (a). Pressing head (1
8), that is, restrained. The constraining system for the roll chock (2 ') is indicated by a code with a dash added to the code for each part of the constraining system along the pass line (a) of the roll chock (2).
