A device for moving the lid removing device by another drive device in the horizontal direction and the vertical direction is known from Japanese Patent Publication No. 51-48161 (capping device for coal charging vehicle). The lid removal is completely horizontal and vertical, but two separate drives are used.

As described above, according to the prior art, the lid cannot be attached and removed accurately and reliably, the height of the device, the movement area for removing the lid is large, and two driving devices are required. There were some drawbacks.

(Problem of the Invention) The present invention is to eliminate the above-mentioned drawbacks of the conventional technology.

(Means for Solving the Problems) According to the present invention, the above problems can be solved by the configuration described in the utility model registration claim.

(Operation) According to the present invention, the guide 2 and the guide 2 are divided into two for horizontal movement and vertical movement, and two links 9 parallel to each other and a lever 10 are combined to cover the lid 8 during movement. While keeping the frame 8 parallel to the upper surface of the charging hole, the lid 15 is always supported horizontally, and this drive is performed by one common drive unit so that the lid frame can be operated smoothly and reliably. did.

(Example) A horizontal guide 2 having a linear guide surface is fixedly provided on a machine frame 1 through two struts, and is fixed to the machine frame 1 and extends over two struts, and is a guide consisting of a straight line and a curved line. An elevating guide 3 having a surface is fixedly provided. A drive device 4 is arranged on the machine frame 1 and is used for opening and closing the lid removing device, which will be described below. Rollers 5 and 6 are mounted on a moving frame 7 and these rollers 5, 6 are guided in a horizontal guide 2 having a linear guide surface. Moving frame 7
On the side surface close to the lid removing frame 8, a link 9 is pivotally supported on the lid removing frame 8 by a fulcrum B, which is an axis of the roller 5, and a lever parallel to this.
10 links are pivotally supported at a fulcrum A on the side of the movable frame 7 on the side of the lid removal frame 8. A roller 11 is pivotally supported by the arm on the side opposite to the fulcrum A of the lever 10 on the side opposite to the lid removal frame 8, and the roller 11 is guided in the lifting guide 3. The right end (FIG. 1) of the lifting guide 3 is designated as point E. A rod 17 is connected to the tip of the arm of the lever 10 opposite to the lid take-off frame 8 via a turnbuckle, the other end of the rod is pivotally supported by a lever 12 via the turnbuckle, and the other end of the lever is The lever 12 is pivotally supported on a support on the machine frame 1 at a fulcrum F, and the lever 12 is connected to a drive device 4 which is, for example, a pneumatic cylinder at a position between the pivotally supported fulcrum F and the tip of the lever 12.

The ends of the link 9 and the lever 10 on the lid removal frame 8 side are pivotally supported on the lid removal frame 8 at fulcrums C and D, and the lid removal frame 8 is provided with a magnet 14. The magnet 14 is located above the charging hole 16 and thus the lid 15. A lever rotating device 13 is arranged on the lid take-up frame 8 in which a lever is driven via a pneumatic cylinder, and the lever is connected to the magnet 14 via two parallel links for rotating the magnet 14. It is set up.

(Operation Method of the Invention) The lever 12 is moved by the operation of the drive device 4, and thereby the roller 11 pivotally supported by the lever 10 is moved in the lifting guide 3. The moving frame 7 moves the rollers 5 and 6 by the swing of the lever 10.
Is horizontally moved along the fitted horizontal guide 2.
That is, when the lever 10 moves, the lever 10 moves the moving frame 7 together horizontally, so that the fulcrum A also moves at the same time as the roller 5 of the moving frame 7.
The fulcrum B of the link 9, which is pivotally supported, is also moved horizontally. The lid removal frame 8 is pivotally supported by the moving frame 7 through both the lever 10 and the link 9, and the pivotally supported fulcrums A and B,
Since C and D form one parallelogram (parallel movement mechanism), the lid taking frame 8 always moves horizontally while keeping parallel to the upper surface of the charging hole 16. During this horizontal movement of the lid removal frame 8, the roller 11 pivotally supported by the lever 10 moves along the guide surface of the elevating guide 3 according to the guide curve of the elevating guide 3, so that the lever 10 is swung. Lifting the lid removal frame 8 to the guide 3
From point E on the right end of the, a gentle descent, horizontal movement, and a descent near the vertical are made. According to the shape of the guide surface of the elevating guide 3 shown in the figure, when the roller 11 starts to move from the point E, the lid removing frame 8 moves horizontally while descending a little, and then the lid 15 is inserted into the charging hole 16.
Move horizontally until you get close to. When the roller 11 reaches the curved guide surface of the elevating guide 3, the lid take-off frame 8 is kept horizontal and the lid 15 is lowered toward the charging hole 16 at a steep angle, that is, substantially vertically. When the roller 11 further advances along the curved guide surface, the lid removing frame 8 is fitted with the lid 15 attracted by the magnet 14.
Abut on 16. Next, the excitation of the magnet 14 is turned off, and the lid 15 is separated from the magnet 14. On the other hand, when removing the lid 15,
The magnet 14 is excited, the lid 15 is attracted, and the lid 15 is rotated by the rotating device 13. Subsequent movement of the lid 15 is performed by the drive device 4 causing the roller 11 to return along the guide surface of the elevating guide 3 to the point E in the direction opposite to the above movement.

(Effect of the device) Since the guide for horizontal movement and the guide for elevation are provided separately, the lid removal frame can be accurately moved horizontally, in parallel, and vertically. Therefore, the lid can be attached and detached accurately, surely and quickly. Therefore, there is no gas leakage after attaching the lid.

Since the lid removing frame is always horizontal and never tilted, the mounting angles of the rotating device 13 and the magnet 14 are always parallel and do not change. As a result, the rotation device 13 and the magnet 14 can be easily attached, their adjustment is facilitated, the movement is ensured, and the lid is easily rotated.

Since the lid removal frame is moved horizontally and in parallel, the height is low,
Installation space is reduced.

The lid drive frame 8 can be continuously and quickly moved accurately and horizontally and parallelly by one drive device 4.
