Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reversing machine for vertically reversing a large and heavy flat object such as a sheet pallet.

[0002]

[Prior art]

 Conventionally, a reversing machine that vertically inverts a large and heavy sheet pallet has a structure in which the sheet pallet conveyed by a roller conveyor is dropped by its own weight along a semi-cylindrical reversing guide plate to invert the sheet pallet 180 degrees. .

In Japanese Utility Model Laid-Open No. 62-74618, the thickness of the bag body to be inverted is 1.5 times to 2. There is described a reversing device for a filling bag having a reversing guide plate which is provided over a range of about 180 degrees on the side opposite to the roller conveyor at a distance of 5 times. Further, in Japanese Utility Model Laid-Open No. Sho 61-108223, a flat object continuous consisting of a belt conveyor and an endless press belt, which is in contact with the outer peripheral surface of a transfer end of the belt conveyor, is in contact with the outer peripheral surface of the belt for more than a half of the belt in a synchronous manner. A reversing device is described.

[0004]

[Problems to be solved by the device]

 The conventional sheet pallet reversing machine has a structure in which the sheet pallet rolls down due to its own weight and then collides against the bottom plate of the reversing machine and collides with the bottom plate of the reversing machine. If it is made of a steel plate, noise of 113 to 115 DB is generated and the working environment is deteriorated. Further, the reversing device described in both of the above publications is not suitable for reversing a large and heavy object such as a sheet pallet.

It is an object of the present invention to solve the above problems and to provide a reversing machine that prevents the work and the reversing machine itself from being damaged and suppresses the generation of noise.

[0006]

[Means for Solving the Problems]

 The present invention has a plurality of sets of wires in which a U-shaped work passage is formed vertically between the upper work input opening and the lower work extraction opening in the horizontal direction, and the work falling portion of the passage has a different inclination angle. Is a reversing machine such as a sheet pallet, in which a work dropped by its own weight is reversed while sliding down on the wire by applying a predetermined tension through a spring.

[0007]

[Action]

 The work that has passed through the passage from the work input port on the upper stage falls in the U-shaped passage and collides with the first set wire with a strong impact, slides down on this wire and reverses, and The collision weakened the momentum and slipped on the next two wires, and proceeded to the work take-out port.

【Example】

 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a perspective view of a sheet pallet, and FIG. 3 is a schematic side view of FIG. Reference numeral 1 denotes the body of the reversing machine, and the inside of the body is shown in FIG. 1 except for the upper wall and the right side wall of the body 1. An inlet 2 for the sheet pallet W is provided on the upper side of the main body 1 of the reversing machine, and a roller conveyor 3 is installed so as to be in contact with the inlet for the work, and the other side of the main body 1 of the reversing machine also serves as a sound insulator. The semi-cylindrical wall 4 is installed to form a U-shaped work passage, and the work passage is connected to the work take-out port 5 provided at the lower stage of the reversing input port 2.

A plurality of buffer wires for receiving the sheet pallet W are provided at the drop portion of the sheet pallet W at the tip of the roller conveyor 3 in the U-shaped passage formed in the reversing machine body 1. As shown in FIG. 3, the buffer wire is stretched obliquely at a large angle (for example, 47 degrees, indicated by a chain double-dashed line in the figure) between the upper portion of the cylindrical wall 4 and the bottom portion of the reversing machine body 1. The first set wire 7A (four sets are shown in FIG. 1) passed over and a slight sag between the lower part of the cylindrical wall 4 and the work take-out port 5 part (for example, 12.7 degrees). The second set of wires 7B stretched over and the third set of wires 7C stretched horizontally without sagging between the bottom of the cylindrical wall 4 and the work outlet 5 part. Tension is applied to each wire by springs 8A, 8B and 8C. The strength of each spring 8A, 8B, 8C may be set appropriately according to the weight of the sheet pallet W. For example, the spring 8A is the strongest and the springs 8B, 8C are weaker in this order.

As shown in FIG. 2, the sheet pallet W is one in which pillows 10 are attached to both sides of one side of a frame body 9, and a panel or the like is placed and used for transportation. When the sheet pallet W is placed on the roller conveyor 3 and fed from the work input port 2, the roller conveyor 3 is inclined, so that the sheet pallet W travels to the right in FIG. 3 and begins to drop at the end of the roller conveyor 3. . As shown by the solid line in FIG. 3, the first group wire 7A is stretched along the passage of the sheet pallet W, so that the sheet pallet W collides with the first group wire 7A with a strong impact, and the spring It is buffered by 8A and slides down on the first set wire 7A. The sheet pallet W loses momentum due to the collision with the first set wire 7A and is reversed, and slides on the second set wire 7B, and the sheet pallet W that has further weakened the force on the horizontal third set wire 7C. Slide and stop by hitting the stopper 6 at the bottom of the work take-out port 5.

The sheet pallet W dropped at the tip of the roller conveyor 3 collides with the first set wire 7A and the second set wire 7B, and the momentum of its own weight is diminished and reversed, so that the sheet pallet W falls on the third set wire 7C. In the inverted state (shown by the one-dot chain line W ′ in FIG. 3), the vehicle slides and stops at the stopper 6. Therefore, since the sheet pallet W does not directly collide with the reversing machine main body 1, damage to the reversing machine and the sheet pallet W due to the drop of the sheet pallet W by its own weight is prevented, and noise generation is suppressed. The actual noise measurement was 97 to 100 DB.

In the above embodiment, the sheet pallet inversion is described, but the present invention is not limited to this and can be applied to a reversing machine for similar articles, and the tip of the work input port 2 or the roller conveyor 3 can be applied. Noise can be further prevented by suspending a vinyl sound insulation sheet on the upper wall of the section.

[Effect of device]

 The present invention has a simple structure in which multiple sets of buffer wires are attached to a conventional reversing machine, which can prevent the reversing machine itself and the work from being damaged and suppress the generation of noise to improve the working environment. Can be good.
