[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing machine for reversing a large and heavy flat object such as a sheet pallet.

[0002]

2. Description of the Related Art Conventionally, a reversing machine for reversing a large and heavy sheet pallet vertically is configured to drop a sheet pallet conveyed by a roller conveyor by its own weight along a semi-cylindrical reversal guide plate, and to reverse the sheet pallet by 180 degrees. It has become.

[0003] Japanese Utility Model Application Laid-Open No. 62-74618 discloses that the width of a bag to be inverted is 1.5 to 2.5 times over a range of about 180 degrees opposite to a roller conveyor. A reversing device for a filled bag body having a reversing guide plate provided is described. In addition, 61-108223
The publication discloses a flat object continuous reversing device composed of a belt conveyor and an endless presser belt that runs synchronously with a part of the belt area pressed against the outer peripheral surface of the transfer end of the belt conveyor over half a circumference or more.

[0004]

The above-mentioned conventional sheet pallet reversing machine has a structure in which the sheet pallet is inverted by its own weight while dropping and falls and collides on the bottom plate of the reversing machine, and the collision causes damage to the reversing machine itself and the sheet pallet. In addition, if the bottom plate of the reversing machine is made of a steel plate, 113-115D
The noise of B is generated, and the working environment deteriorates. Further, the reversing devices described in the above publications are not suitable for reversing large and heavy objects such as sheet pallets.

[0005] The present invention solves the above problems and provides a seat.
An object of the present invention is to provide a reversing machine that prevents damage to a pallet and the like and the reversing machine itself and suppresses generation of noise.

[0006]

According to the present invention, an upper sheet is provided.
A U-shaped passage is formed up and down in the lateral direction between the inlet of the pallet and the outlet of the lower sheet pallet and the like, and a plurality of sets of wires having different inclination angles are springed at the falling part of the passage such as the sheet pallet. A sheet pallet or the like that applies a predetermined tension to the sheet pallet through the wire and turns over while falling down on the wire while falling down on the wire.

[0007]

[ Function ] Seat pallet that has advanced through the passage from the upper input port
Etc. fall in a U-shaped passage, collide with the first set of wires with a strong impact, slide down on this wire and invert, and in the collision with the first set of wires the momentum weakens and the next second set Sliding over the wire and proceeding to an outlet for sheet pallets and the like .

1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a perspective view of a seat pallet, and FIG. 3 is a schematic side view of FIG. 1 is a main body of the reversing machine, and FIG. 1 shows the inside of the main body 1 except for an upper wall and a right side wall. An input port 2 for the sheet pallet W is provided on the upper side of one side of the reversing machine main body 1, and a roller conveyor 3 is installed in an inclined state in contact with the input port. A U-shaped passage was formed by installing the cylindrical wall 4 and provided at the lower stage of the reversing inlet 2.
It is connected to the sheet pallet outlet 5.

[0009] A plurality of sets of buffer wires for receiving the sheet pallets W are installed in the falling portion of the sheet pallets W at the tip of the roller conveyor 3 in the U-shaped passage formed in the reversing machine main body 1. This buffer wire, as shown in FIG.
Large angle (e.g. 47 °, shown by the one-dot chain line in the drawing) obliquely to the upper and bottom of the reversing machine body 1 of the cylindrical wall 4 first pair wire 7A (in Figure 1 4 passed significantly slackening in tension in Set is shown) and a small angle (e.g., 12.7 degrees) between the lower part of the cylindrical wall 4 and the sheet pallet outlet 5 part.
With the second set of wires 7B that were slightly slackened and stretched over,
A third set of wires 7C extending horizontally without sagging between the bottom of the cylindrical wall 4 and the sheet pallet outlet 5
Each of these wires has a spring 8
A tension is applied at A, 8B and 8C. Each spring 8A,
The strengths of 8B and 8C may be appropriately set according to the weight of the sheet pallet W. For example, the strength of the spring 8A is set to be the strongest, and thereafter, the strength of the springs 8B and 8C is set to be weak.

As shown in FIG. 2, the sheet pallet W has pillows 10 attached to both sides of one side of a frame 9, and is used for carrying a panel or the like on the sheet. When a sheet pallet W is loaded on the roller conveyor 3 from the sheet pallet inlet 2 and fed in, the sheet pallet W travels rightward in FIG. Begins to fall. As shown by the solid line in FIG. 3, the first set of wires 7A is slackened and stretched along the path of the sheet pallet W, so that the sheet pallet W collides with the first set of wires 7A with a strong impact,
It is buffered by the spring 8A and slides down on the first set of wires 7A.

The sheet pallet W has a first set of wires 7A.
Momentum weakens in the collision with and turns over, the second set of wires 7B
Sliding up, sheet pallet W weakened further
(Shown by a dashed line W ′ in FIG. 3) is a horizontal third set of wires.
-7C on the stopper 6 under the outlet 5
Hit and stop. Therefore, since the sheet pallet W does not directly collide with the reversing device main body 1, damage to the reversing device and the sheet pallet W itself due to the falling of the sheet pallet W under its own weight is prevented, and noise generation is suppressed. In the noise measurement of the actual machine, it was 97 to 100 DB.

In the above embodiment, the reversal of the sheet pallet has been described. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a reversing machine for similar articles. The noise can be further prevented by suspending a vinyl sound insulation sheet on the upper wall of the tip of the third.

[0013]

[Effects of the Invention] The present invention has a simple structure in which a plurality of sets of buffer wires are attached to a conventional reversing machine.
It is possible to prevent damage to the seat pallet and the like, and to suppress the generation of noise to improve the working environment.
