Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bowl feeder Z in which two bowls are combined into a unit so as to vibrate in opposite phases.

Conventional electromagnetic vibration type bowl feeders have multiple leaf springs installed on the top surface of the base at an angle, and the bowl is supported by the free end of the leaf spring at the top so that it can vibrate in a circle, and the bowl is placed on the base. It uses an electromagnet to vibrate the bowl in Z direction.

For this reason, the heavy bowl containing the parts is necessarily supported at a high position from the base, so the center of gravity of the entire bowl feeder is raised, and this, in conjunction with the vibration of the bowl and base, causes the bowl feeder to This makes the installation stability of the system extremely poor. Furthermore, since the bowl is directly fixed to the base via a leaf spring, attaching and detaching the bowl is complicated and time-consuming, and the efficiency of changing the bowl required when changing the parts to be delivered is greatly reduced. It's making things worse. In order to eliminate the above-mentioned drawbacks, the present invention provides two sets of leaf springs by arranging a plurality of leaf springs radially on a holder that is detachably attached to the support part of the base. Two bowls are independently supported at the outer end of the bowl, and a vibrating member is provided between the pair of bowls to form a unit, so that the two bowls are vibrated circularly in opposite phases.

With this, despite having two bowls, he is short,
Mutual vibrations cancel each other out, reducing vibration transmission to the base, dramatically improving the installation stability of the bowl feeder, and allowing the pair of bowls to be easily attached and removed from the base, improving replacement efficiency. Sealing (bowl setup changes) can be done freely. Next, the present invention will be explained with reference to embodiments shown in the drawings.

In the bowl feeder BF of the first embodiment shown in FIGS. 1 to 3, reference numerals 1 and 2 are donut-shaped annular bowls with a hollow center, and the inner circumferential wall has a spiral conveying path of an appropriate width from the bottom to the top. la and 2a are provided. Reference numeral 3 designates a disk-shaped base (table), which is placed on a floor 5 with several anti-vibration rubbers 4 placed on the bottom surface, and has a support column 3a erected in the center of the top surface.

A holder S is detachably attached to the support column 3a, and is fixed to the support column with a set screw 7.

An appropriate gap x is created between the two bowls M and 14 so that the two bowls 1 and 2 can be vibrated circularly in the circumferential direction in an opposite phase relationship. As described above, a pair of bowls 2 each having a vibrating member are attached to one holding body 6 to form a unitized bowl feeder BF. The inclination angle of each leaf spring 8 can be adjusted by using the mounting pieces 9 on both sides, since both ends of the rarely attached leaf spring are cylindrical 8a.・・・、12・・・・・・・・・・・・
You can set it to any angle by loosening... In the second embodiment shown in FIGS. 4 to 6, a pair of annular bowls 1' and 2' have different outer diameters, and the bowl 2' on the small diameter side is connected to the bowl 1 on the large diameter side.
', and the height of the bowl is the same as that of one bowl. That is, the holder 6' arranged on the support column 3a of the base 3 is a hexagonal truncated pyramid, and each pyramidal surface 6'a has three long and three short pyramids.
The base end side of the leaf springs 8, 8' (total of 6 pieces) is fixed with the bolt 20.
It has a modified radial mounting configuration with screws attached. Then, the bottom part 1'b of the large diameter bowl 1' is attached to the outer ends of the three long leaf springs 8 by the support 21...
At the same time, the bottom part 2'b of the small diameter bowl 2' is attached to the outer ends of the three short leaf springs 8' by the support 22. Make it stick. Now, the two bowls 1', 2' are supported as a pair by the leaf springs 8, 8' independently in the internal and external mounting relationship. , an electromagnet M is placed in the bottom 2'b space of the bowl 2' on the small diameter side.
・A suction iron piece 14 is attached and faces the suction iron piece 14.
. . . is attached to the bottom 1'b of the bowl 1' on the large diameter side. As described above, one holding body 6'
A pair of bowls 1' and 2' each having a vibrating member are attached to the bowl feeder BF to form a unitized bowl feeder BF. The holding body 6' has a through hole 6'b aligned with the support column 3a of the base 3, and is fixed to the seat 3b of the support column using the bolt 301 of the textbook.The present invention The bowl feeder BF is constructed as described above and operates as follows.

The two unitized bowls 1, 1\ 2, 2' are
The support columns (supporting parts) 3a of the base 3 are supported by the holders 6 and 6'.
It is attached to the base by a set screw 7 or a bolt 38'. The installation height of this bowl is the same as that of the conventional bowl.
Because it is lower than the Wolf Feeder, the center of gravity is low even when parts are placed in the bowl, allowing for stable installation.The vibration of the electromagnet M causes each bowl to move, 1', 2,
The circular vibrations generated at 2' are in antiphase with each other, and their vibration energy cancels out in the holders 6 and 6'.Therefore, there is almost no vibration transmission of the bowl to the base 3, so it is difficult to place the base in place. The electromagnet M efficiently vibrates the pair of bowls without compromising stability, causing the parts in each bowl to circulate in the direction of the chain arrow, and are smoothly transported from the chute to the external machine.Then, the first embodiment Leaf spring 8 like...
If the inclination angle of ... can be freely adjusted, the feeding speed of the parts stored in the two upper and lower bowls 2 can be changed arbitrarily and easily. Furthermore, when lifting the bowl, loosen the set screw 7 or bolt 30 and lift the bowl so that the holders 6, 6' are aligned with the support columns 3a.
The bowl units can be easily pulled out from the base 3, and the pair of bowl units can be separated from the base 3. Here, a new bowl unit prepared separately is fitted onto the support column 3a of the base 3, and tooling of the bowl is completed by tightening the set screw 07 or bolt 30.
That is, the leaf spring 8 and the vibration member M are included in one bowl unit.
, 14, since the pair of bowls 1, 1', 2, 2' are incorporated, there is no need to adjust the leaf spring angle, attach or detach the vibrating member, or adjust the gap each time the bowls 1, 1', 2, 2' are installed. By increasing the length of the bowl unit, it is possible to stack several bowl units.The present invention is not limited to the above two embodiments, and the design can be changed within the spirit of the invention.

For example, in the first embodiment, the leaf spring 8...
It is also possible to use a fixed type as in the second embodiment in which the leaf spring 8 cannot be adjusted.
. . . 8' . . . are arranged in a radial mounting relationship as in the first embodiment, and are adjustable. In the first embodiment, the upper bowl 1 may be shaped like a dish, and in the second embodiment, the opposing walls 1'c, 2'c of the two inner and outer bowls 1', 2' are omitted, and one large bowl shape is used. You can also use it as Furthermore, as shown in FIG. 7, in the configuration of the second embodiment having two types of long and short leaf springs 8, 8', the short leaf spring 8' is arranged in parallel with the long leaf spring 8 via the spacer 40. You can also use it as This has the advantage of widening the space between the leaf springs. Since the bowl feeder of the present invention is as described above,
Although it has two bowls, it is short and allows multiple units to be stacked one on top of the other, and not only can it be stably installed, but the vibrations of the bowls cancel each other out and are transmitted to the base. This dramatically improves the installation stability of the bowl feeder, and also allows the pair of bowl units to be easily attached and detached from the base, providing excellent exchange efficiency and reducing the angle of the leaf springs and the gap between the vibrating members. It exhibits many excellent effects, such as being able to freely perform ringing without any adjustment.
