Description

[Detailed description of the invention] This application proposes that when goods are being moved between a warehouse and the outside, between warehouses, etc., when a fire occurs and the shutters automatically fall, the shutters between the conveyors are moved. This invention relates to a falling gear propeller that can pass through and block partition walls in warehouses to prevent the spread of fire.

The present application also relates to a falling gear roller that can provide rollers that normally communicate between conveyors with a simple construction and at low cost.

Furthermore, the present invention relates to a falling gear propeller that is simple in structure and can operate reliably to pass through the shutter.
Furthermore, the present application relates to a falling gear propeller in which the height of the rollers connecting the conveyors can be finely adjusted by adjusting the protruding length of the bolts.

Furthermore, in this application, once the hook-shaped lever or L-shaped arm is released, it does not come into contact with the shutter.
It is compatible with various shutter shapes, prevents the shutter body from being scratched by the hook-shaped lever, and when raising the shutter, it is easy to operate because the shutter does not interfere with the hook-shaped lever or L-shaped arm. This is an invention related to a falling gear propeller that made this possible.

Furthermore, this invention relates to a falling gear propeller that has a simple structure and can be easily attached to an existing conveyor.

Now, to explain one embodiment, two conveyors 2 and 3 are arranged with a partition wall 1 in between, keeping a constant interval W (for example, 130 mm), and the conveyors 2 and 3 are connected in series. The rear end of the horizontal member 5a of the L-shaped arm 5 having the roller 4 at the upper end of the vertical member 5b is attached to the frame of the conveyor 2 or conveyor 3 on either side of the conveyor 2 or conveyor 3 which are close to each other. 6
The lower end of the vertical portion 8b of the hook-shaped lever 8 is attached to the block 7 which is pivotally attached to the lower part of the horizontal member 5a of the L-shaped arm 5 by a shaft 9, and the center of the block 7 is attached to the frame. The bolt 1 is pivotally connected to the body 6 by a shaft 13, and the bolt 1 is attached to the block 7 on the opposite side to which the hook-shaped lever 8 is attached so that the protruding length can be freely adjusted upward.
0 protruding from the horizontal member 5 of the L-shaped arm 5.
The angle member 11 that contacts the head of the bolt 10 when the bolt 10 is kept horizontal is fixed to the horizontal member 5a, and the head of the bolt 10 is engaged, and the bolt 1
The upper surface of the roller 4 is normally positioned flush with the upper surfaces of the conveyors 2 and 3 by adjusting the protrusion length of the roller 0, and the front end of the horizontal portion 8a of the hook-shaped lever 8 is raised slightly above the upper surface of the roller 4. The positional relationship between the head of the bolt 10 and the angle member 11 is set so that the bolt 10 stops at a slightly inclined position toward the shaft 9, so that the upper part of the vertical portion 8b stops at a slightly inclined position toward the shaft 9.

That is, the bolt 10 is inclined toward the shaft 9, the vertical portion 8b of the hook-shaped lever 8 and the bolt 10 are attached parallel to each other, and the angle member 11 is attached to the head 1 of the bolt 10.
0a, the horizontal member 5a of the L-shaped arm 5 remains horizontal. The block 7 is provided to intersect the vertical portion 8b of the hook-shaped lever and the bolt 10 at right angles.

The head 10a of the bolt 10 is formed into a hemisphere.

The L-shaped arm 5, the hook-shaped lever 8, the block 7, the bolt 10, and the angle member 11 are provided in pairs on the left and right sides of the conveyor 2 or the conveyor 3, and the L-shaped arm 5 is connected to the shaft 4a of the roller 4, the auxiliary shaft 12, and the shaft 1.
3 and are fixed together so that they can operate on the left and right sides as one.

The roller 4 is rotatably attached to a shaft 4a.

The aforementioned L-shaped arm 5, block 10, and shaft 9 may be attached directly to the frame 6 of the conveyor 2 or conveyor 3, but they may also be attached to a U-shaped side channel 14 attached to the frame 6 as shown. It is something.

The operation of the present invention will be explained based on the above-mentioned structure. When an accident is detected and the shutter 15 automatically falls, the lower end of the shutter 15 comes into contact with the horizontal portion 8a of the hook-shaped lever 8, and the block 7 is axis 1
3 as a fulcrum and lifts the bolt 10. At this time, the angle member 11 rises once, so the L-shaped arm 5 also raises its end (the side where the roller 4 is attached), but the bolt Once the angle member 10 becomes vertical, it is removed from the lower surface of the angle member 11. Therefore, the hook-shaped arm 8 rotates counterclockwise and rotates to the lower part of the conveyor 3, so that the L-shaped arm 5 also rotates counterclockwise and moves to the bottom of the conveyor 3 since the bolt 10 and the angle member 11 are no longer engaged.
Rotate to the bottom of.

Due to this action, there is nothing intervening between the conveyors 2 and 3, so the shutter 15 falls to the bottom of the conveyor 2 and conveyor 3 without being obstructed, blocking both sides of the shutter 15 and serving as fire prevention. It is something that does. To return to the original position, it is sufficient to lift the L-shaped arm 5 and the hook-shaped lever 8 by hand, engage the bolt 10 and the angle member 11, and stop.

As described above, two conveyors 2 and 3 are arranged with a constant interval W between them with a partition wall 1 in between, and either one side of the conveyors 2 and 3 which are arranged in series is close to each other. An L-shaped arm 5 with a roller 4 at the upper end of a vertical member 5b at the end of the conveyor 2 or conveyor 3
The rear end of the horizontal member 5a is pivotally connected to the frame 6 of the conveyor 2 or the conveyor 3 with a shaft 9, and the L-shaped arm 5
The lower end of the vertical portion 8b of the hook-shaped lever 8 is attached to a block 7 which is pivotally attached to the lower part of the horizontal member 5a, and the center of the block 7 is pivotally attached to the frame 6 by a shaft 13. At 7, a bolt 10 is attached to the side opposite to where the hook-shaped lever 8 is attached, so that the protrusion length can be adjusted freely, and the horizontal member 5 of the L-shaped arm 5 is attached.
fixing the angle member 11 to a, engaging the head of the bolt 10, and adjusting the protruding length of the bolt 10 to position the upper surface of the roller 4 flush with the upper surface of the conveyor 2 and the conveyor 3; Since the horizontal part 8a of the hook-shaped lever 8 is located above the upper surface of the roller 4, when a shutter or the like falls and comes into contact with the hook-shaped lever, it will operate reliably and position the roller between the conveyors at the bottom of the conveyor. It is possible to quickly drop the shutter to the bottom and shut off both sides of the shutter, the structure is simple and inexpensive, it can be easily installed on conventional conveyors, and the protruding length of the bolt can be reduced. By adjusting the height of the rollers that connect the conveyors, it is possible to finely adjust the height of the rollers that connect the conveyors.In particular, in this application, once the hook-shaped lever or L-shaped arm is released, it does not come into contact with the shutter. Compatible with various shutter shapes, the hook-shaped lever does not damage the shutter body, and when raising the shutter, the shutter does not interfere with the hook-shaped lever or L-shaped arm, making it easy to operate. It has the following effects.
