Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to vibration feeders, and more particularly to an apparatus for adjusting a leaf spring of a vibration feeder.

That is, the invention provides interchangeable elements in the suspension structure,
The purpose is to adjust the angle of the leaf spring attachment of the feeder.

A typical vibrating pole feeder having a base, a driven element attached to the base by a spring, is vibrated by an electromagnetic exciter. The operating frequency of the exciter is determined by the line frequency of the power source.

The feeding speed changes according to different materials and articles, and according to the amount and form of material that can be fed, the pole feeder must have a certain degree of flexibility, so the angle of movement can be adjusted to a certain extent. It is hoped that this will be obtained.

The present invention has a second leaf spring mounting block 41, each block having a different apex angle on the spring contact surface. A plurality of spacers are provided, including a flat spacer and a spacer with a typical 5° apex angle, thereby adjusting the effective angle of the first leaf spring mounting block and the second leaf spring mounting block. . The spacers, hereinafter referred to as flat spacers and wedge members, are formed with mounting bolt receiving openings which allow the leaf spring mounting bolts to pass through the spacers and to the drilled and tapped mounting block. go inside.

The vertical acceleration of the ball feeder can be advantageously controlled and selected by adjusting the mounting angle of the ball support spring. The present invention allows angle adjustment by using a series of elements to support the ball.

Advantages and configurations of the invention will become apparent by reference to the following description and accompanying drawings.

FIG. 1 is a plan view of a vibrating ball feeder αO), in which the feeder αQ has a base α supporting a cross arm (14), and a ball (not shown) is attached to the cross arm (14) in the usual manner. ) is installed. Each extension of the loss arm is individually formed in the group i2G of leaf springs as indicated by the designation number (16). Each leaf spring group (2I is composed of a single leaf spring or a plurality of leaf springs,
The leaf spring group is merely representative of a preferred embodiment.

The elevational view in Fig. 2 shows the cross arm 0 which is a support member, and the extension part αe supported with respect to the base by a group of four leaf springs as indicated by the instruction number (A). shows. The base plate has a substantially rectangular shape with a considerable amount of mass, and the base plate has a notch shown with an instruction number (2) so that the leaf spring can be accommodated around the device. It is formed.

Each cut portion (2) extends perpendicularly from the periphery of the base toward the center, and is referred to as the base surface of the base cut portion below the first surface at least) is formed to be inclined with respect to the vertical reference line (A) The angle of this base plane is 25° in the preferred embodiment.

According to FIG. 2, an extension part having an extension part surface (to) is shown, and the extension part surface (to) has a perpendicular reference line (to) in a direction opposite to the angle of the base surface of the base notch. (to). The angle of this base plane is 15° in the preferred embodiment.

A through hole is formed at the end of each plate spring (20) to accommodate three spring fixing bolts.In this example, eight identical bolts are used, but other fixing structures may be used. The bolts are finally screwed into the screw holes in the base surface of the base a2 (2a1 and the extension surface of the cross arm α). are drilled at an angle of the same degree of inclination with respect to the horizontal plane. In this example, the screw holes are bored parallel to each other and inclined at 20° with respect to the horizontal plane.

A plurality of flat spacers and wedge members are provided to allow adjustment of the mounting angle of the leaf spring. That is, the flat spacer is formed of rectangular material, has a constant thickness and wide flat surfaces on both sides. These flat surfaces are approximately parallel to each other. These flat spacers, indicated by reference number (40) in FIG. 2, are provided with holes through which spring fixing bolts C+a pass.

The wedge member shown in FIG.
1 is parallel to the vertical plane, but the second plane (4fn) is inclined at 51 with respect to the vertical plane, that is, 5° with respect to the first plane.

A hole for accommodating the spring fixing bolt is also formed in the wedge member.

As shown in Figures 3 to 5, flat spacers (40
) and the wedge member (42) are arranged opposite to the leaf spring group t2o+i so that various leaf spring angles can be realized.

In FIG. 3, the leaf springs are positioned at an angle of 15 DEG with respect to the vertical, as indicated by the included angle A. As can be seen from FIG. 3, the example extension surface is formed on the extension part 16) of the cross arm so as to be inclined at 15 degrees from the vertical reference line (26), as indicated by the reference number (50). Ru. Further, on the base t1, as indicated by the reference number (52), a base surface (to) is formed at an angle of 25° from the vertical reference line (26). The surfaces of these extensions (to),
Although the angle of the base surface (241) is constant in the illustrated embodiment, various angles can be provided as desired.

In the embodiment of the leaf spring shown in FIG. 3, the following spacer structure is used to achieve a 15° angle in the leaf spring. Since the extension surface (30) of the cross arm is already provided with an angle of 15°, no spacer is required between the upper end of the leaf spring group and the extension surface (to). Wedge member (4
2 is placed at the outer end of the leaf spring group, so that the head of the spring fixing bolt contacts the surface perpendicular to the main axis of the screw hole I3a, so that the bolt does not bend even when a deflection load is applied. be done. The wedge member (42 provides a surface parallel to the surface (to) the extending portion of the cross arm. The base surface (2)
) is formed at an angle of 25" with respect to the vertical line (2) with a l
These two identical wedge members (42a) and (42b) are used. These two wedge members (42a), (42
b) with their vertical surfaces abutting each other; Therefore, using such a wedge member, the actual bevel angle of the base surface will be reduced from 25° to 10". A single wedge member (42C) is used outside the spring group in this area. , this causes the bolt head (32a) to be 2
The bolt is in contact with the 0' inclined shaft, and the bolt is prevented from deflecting even if a deflection load is applied to the bolt.

In the actual auction shown in Fig. 4, the leaf spring group -〇 and the vertical reference line (2
The groove angle between 6) and 6) is 20°. of course,
These elements are similar to those shown in Figures 1, 2, and 3, except that the flat spacer and wedge elements are used in a different arrangement.
The members are the same as those used in the figure. Especially in the cross arm part, the plate spring group 1. A wedge member (42d) is used between lα and the extending part surface (to), and the angle at which the instruction number G of the extending part surface (to) is placed is increased from 15° to 20°.

Since this extension surface provides a complementary angle to the spring fixing bolt 132), a flat spacer (40) is used on the outside of the spring group. Regarding the base,
In the part where the base surface is 25° as indicated by the instruction number (52), a wedge member (42e) is used between the plate spring group CO and the vertical reference line (a) to make the bevel angle 20°. . Only flat spacers are used on the outside of this part of the leaf spring group (20), which results in a concentric load on the spring fixing bolts (32).

In the embodiment shown in Fig. 5, wedge members (42f) and (42g) of 5° are installed between the plate spring group and the extending portion surface (to), so that the angle of 25° is The bevel angle is given. Another wedge member (42h) K is used on the outside of the top of the leaf spring group, and the wedge member (42h) that contacts the spring group is used so that the load is concentrically applied to the spring fixing bolt 04.
42h) is sloped at 20°. Regarding the base, since the base surface (to) is inclined at 25 degrees, there is no need for a wedge member, and the temporary spring group is directly attached to the base surface c! However, they can be installed side by side. However, in order to align the spring fixing pole l-(32a) with the screw hole of the cross arm, the wedge member (42J
) is used.

While this specification describes a wedge member having an inclination of 5" from the vertical plane, and specific angular displacements of the extension and base surfaces, these are merely illustrative of preferred embodiments, and therefore The angles of these members can be varied;
It can be said that those modifications are also included within the scope of the present invention. Furthermore, the quantity of elements disclosed is not critical to the invention. Therefore, it is also possible to form four or more cut portions in the base and provide the cross arm with a corresponding number of extension portions.

As is clear from the above description, by using a set of flat spacers and wedge members, a vibratory ball (container) feeder in accordance with the object of the present invention is obtained in which the angle of the spring can be adjusted. Several design changes are possible to the present invention and are considered to fall within the scope of the claims herein.
