Description

[Detailed description of the invention] This invention has a separate type hopper bottom plate, and a spiral conveyance path established along the outer periphery of the cylindrical part at the center of the separation bottom of the bottom plate connected to the vibrating body. It concerns conveyors.

2. Description of the Related Art Conventionally, there is a vibrating conveyor as shown in FIG. 1, which continuously conveys a large amount of workpieces from below to above.

In the same figure, 1 is the electromagnet installed on the machine base 2, 3
4 is a movable plate that is vibrated by the electromagnet 1, and 4 is a vibrating body for mounting the hopper 6, which is fixed to the movable plate 3 and supported by an inclined plate spring 5 whose lower end is fixed at four points on the circumferential side of the electromagnet 10. , 7 is a spiral conveyance path established above the hopper 6.

In this case, the conveyance path 7 protrudes from the cylindrical portion 8 in the horizontal direction,
A side plate 9 is erected integrally with this, and this serves as one unit.
A plurality of them are connected in series with bolts 10.

As a result, in this conventional example, the conveyance path 7 can be formed of a single casting, and although it has the advantage of being relatively easy to manufacture, it has the disadvantage of lacking conveyance ability and impairing its function as a vibrating conveyor.

In other words, the workpiece is transported by the hopper 6 by intermittent operation of the electromagnet 1.
In addition, by vibrating the conveyance path 7 in the circumferential direction and vertical direction, the movement is carried out from inside the hopper 6 upward along the conveyance path 7. At this time, the mass of the workpiece inside the hopper 6 is vibrated. This affects the capacity (the excitation force applied to the conveyor 7 by the electromagnet 1), and the mass of the workpiece changes sequentially, making it difficult to maintain a constant conveyance capacity.

Further, in this conventional example, since the structure is such that the hopper 6, which does not contribute to the conveyance of the work, is also vibrated, there is a drawback that the capacity of the hopper 6 cannot be increased with the electromagnet 1 having the same vibration capacity.

On the other hand, in order to suppress fluctuations in conveyance capacity due to changes in the mass of the workpiece, a hopper with a separate bottom plate has been developed.

FIG. 2 shows the device.

As shown in the figure, the separation bottom 11 is fixed on an immovable base 12, and a spiral conveyance path 14 provided along the peripheral side wall of the hopper 13 is supported by an inclined leaf spring 15.

In such a separating bottom type device, the workpiece in the hopper 13 is supported by the separating bottom 11,
The influence of workpiece mass fluctuations on conveyance capacity is reduced to a negligible extent.

Therefore, the vibration of the electromagnet 16 is directly transmitted only to the conveyance path 14, which has the advantage that a constant conveyance capacity can be maintained.

Therefore, in view of the above-mentioned drawbacks of the conventional vibrating conveyor, the present invention improves and eliminates the drawbacks while effectively utilizing the advantages of the separate type vibrating conveyor.

The configuration of the present invention will be explained below according to embodiments shown in the drawings.

As shown in FIG. 3, a separation bottom 17 is fixed to a vibrating body 18, and a hopper 19 is fixed to a counterweight 21 via its bottom plate 20, or directly to an immovable base 22.

Reference numeral 23 denotes a cylindrical member fixed to the separation bottom 17 and the vibrating body 18, and a spiral conveyance path 24 is attached to the outer periphery of this cylindrical member at an angle of inclination α above the horizontal direction.

The vibrating body 18 is supported by an inclined plate spring as in the conventional case,
The structure is such that it is vibrated in the rotational direction and the vertical direction using an electromagnet (both not shown) or the like.

The vibration of the vibrating body 18 is directly transmitted to the conveying path 2 on the outer periphery of the cylindrical member 23.
4, and the works in the hopper 19 are sequentially taken out and placed on the conveyance path 24 in accordance with this vibration.

When the workpiece is placed on the conveyance path 24, it is thrown upward from below and conveyed, and then is supplied from the upper end to the next process by another conveyance means.

In this case, the workpiece is thrown upward in the radial direction due to the rotation and vertical vibration, so there is a risk of it jumping out of the conveyance path 24, but this is prevented by the inclination angle α of the conveyance path 24.

That is, in the hopper 19, most of the mass of the workpiece acts on the fixed bottom plate 20, and since the hopper 19 itself is a fixed body, the performance of the vibration source is not reduced.

Therefore, with the above structure, the hopper 19 can be expanded in the outer circumferential direction, and the height of its side wall can be increased, making it possible to perform large-capacity processing (for example, storing and transporting a large amount of workpieces).

In addition, the mass acting on the vibration source is the cylindrical portion 23 and the conveyance path 24.
A substantially constant value is obtained due to the workpiece on the conveyance path 24,
And? Since the mass of the workpiece on the bottom plate 20 during storage does not act, the vibration capacity is effectively consumed only for transporting the workpiece, and if the vibration source is the same, high-lift processing is possible, and if the lift is the same, the vibration source is lighter. This results in miniaturization and a certain level of work efficiency due to the predetermined conveyance capacity.

Furthermore, the cylindrical portion 23 and the conveyance path 24 have the function of pushing out the workpieces staying in the hopper 19 in the direction of the outer circumference due to vibrations, so they work to disperse the workpieces and prevent the workpieces from having complicated shapes as in the past. No clogging will occur even if the

It is arranged between the central separation bottom of the hopper and the immovable base, and consists of a vibrating body that electromagnetically vibrates the separation bottom in the rotation direction and the vertical direction, resulting in stable large capacity and high head conveyance. It is possible to provide a vibrating conveyor that allows processing.
