た電磁式直進振動フィーダに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vibration feeder, and more particularly to an electromagnetic linear vibration feeder provided with vibration amplification means.
直進型の振動フィーダの振動源として最近では圧電素子
等を用いたものも開発されているが、発生する振動エネ
ルギーが小さい等のため、その用途は限定され、振動源
の主流はやはり電磁力である。Recently, devices using piezoelectric elements have been developed as vibration sources for linear type vibration feeders, but their use is limited because the vibration energy generated is small, and the mainstream of vibration sources is still electromagnetic force. be.
第４図は従来の振動フィーダの構成を示す。FIG. 4 shows the configuration of a conventional vibratory feeder.
粉粒体を充填したホッパ３２は二枚の板バネ３０及び３

う振動フィーダの固定板３５に固定した電磁石である。The hopper 32 filled with powder and granules is connected to two leaf springs 30 and 3.
1, and a suction plate 33 is fixed to the hopper 32 side. Reference numeral 34 denotes an electromagnet fixed to the fixed plate 35 of the vibrating feeder so as to face the suction plate 33.

せる。By applying an alternating current voltage to the electromagnet 34, the electromagnet intermittently emits magnetic force in response to the cycles of this alternating voltage. As a result, the suction plate 33 receives the intermittent suction force of this electromagnet and the leaf spring 30.3 that springs in response to this suction force.
It vibrates due to the cooperation with 1. This vibration is caused by the hopper 32
The powder and granules filled inside are transferred to the discharge end 32a.
The liquid is moved toward the outside and discharged from the discharge end.

精度が低下するので特に問題である。In the conventional configuration shown above, the distance from the suction center of the electromagnet 34, that is, the axis 36 of the iron core 34a of the electromagnet 34 to the powder filling surface is not large because the suction plate 33 is suspended. It cannot be taken. In other words, since the moment arm during vibration has approximately this distance, it is necessary to increase the gap G between the end face of the iron core 34a and the suction plate 33 in order to increase the amplitude. However, if the gap G is large, a large suction force is required to attract the suction plate 33, and as a result, a strong and large electromagnet 34 must be used, and the entire vibrating feeder becomes large and large.
It will add a lot of weight. Fig. 5 shows the relationship between the gap G and the suction force. As is clear from this figure, the suction force increases by 1/10" as the gap G increases (for example, n#1 to 5
). For items such as drugs where the amount to be cut out must be set very accurately, a method is to place the vibrating feeder on a precision weighing device such as an electronic balance and control the cutting out of the powder or granules being dropped. However, in this case, as mentioned above, when the vibrating feeder becomes large and heavy, the dead load of the weighing device becomes large and the accuracy of weighing decreases, which is a particular problem.

した電磁石型の振動フィーダである。The present invention has been constructed in view of the above-mentioned problems, and includes an electromagnet disposed opposite to a plate spring that supports a part for disposing powder or granules such as a hopper, and powder particles from a suction part of the electromagnet in this plate spring. By setting a large distance to the body placement surface, the moment arm during vibration is set to be large.
In some cases, this is an electromagnet-type vibratory feeder in which an electromagnet is installed so as to be movable along this leaf spring, and the moment arm is made variable.

幅を得ることが可能となる。An electromagnet is arranged opposite to the leaf spring, and the electromagnet suction part of the leaf spring and the powder s! By setting a large distance between the mounting surfaces, the moment arm during vibration is set to be large, so it is possible to amplify small-amplitude vibrations in the electromagnet suction part with this large moment arm. Therefore, it is possible to obtain a large amplitude with a small electromagnet.
以下本発明の実施例を図面を参考に具体的に説明する。Embodiments of the present invention will be specifically described below with reference to the drawings.
第１図は本発明の第１の実施例を示す。FIG. 1 shows a first embodiment of the invention.

に構成しである。In the figure, reference numerals 1 and 2 indicate leaf springs, each of which has its lower end fixed to a fixed plate 3 and whose upper end supports a hopper 4. 5 is an electromagnet, and an iron core 6 of this electromagnet 5 is located opposite to an attraction plate 7 attached to the leaf spring 2. In this case, the center of suction in the leaf spring 2 (the position where the axis 8 of the iron core 6 passes through the temporary spring 2) is located below the leaf spring 2, for example, from the lower fixed part of the leaf spring 2 to the suction center. The ratio of the distance a to the distance from the suction center to the bottom of the hopper is set to 1:2, and the distance ' from the suction center to the powder placement surface, that is, the moment arm during vibration, is set large. In this case, the gap G between the iron core 6 of the electromagnet 5 and the suction plate
is set narrowly so that the leaf spring 2 vibrates with a small suction force.
小さな吸引力でもモーメントアームｂを大きく設定しで
あるので、粉粒体載置面における振動は大きく増幅され
る。従って前記電磁石は小型のものでよく、振動フィー
ダ全体を軽量化することが可能である。Since the moment arm b is set large even with a small suction force, vibrations on the powder placement surface are greatly amplified. Therefore, the electromagnet may be small, and it is possible to reduce the weight of the entire vibratory feeder.
第２図及び第３図は第２の実施例を示す。2 and 3 show a second embodiment.
この実施例では電磁石５を板バネ２に沿って移動可能な
ように構成し、これにより振幅を調節するように構成し
である。In this embodiment, the electromagnet 5 is configured to be movable along the leaf spring 2, thereby adjusting the amplitude.
９は電磁石を取りつける取り付は台であり、この取り付

なように構成しである。これにより電磁石５を仮バネ２
に沿って所定の位置に移動後固定し、仮バネ２における
モーメントアームを変更可能なようにしている。Reference numeral 9 designates a base on which the electromagnet is attached, and the base 9 is fixed to the fixed plate 3 with screws 10. The insertion portion of the screw 10 is formed as an elongated hole 3a formed so that its longitudinal direction coincides with the longitudinal direction of the temporary spring 2, and the elongated hole 3a allows the mounting base 9 to be moved. It is. This causes the electromagnet 5 to become the temporary spring 2.
The temporary spring 2 is moved to a predetermined position and then fixed, so that the moment arm of the temporary spring 2 can be changed.
第３図は電磁石取り付は部の詳細を示す。Figure 3 shows details of the electromagnet mounting section.

により鉄心６の移動面１１と吸引板７との成す角もαと
なるため、例えば鉄心６の軸心が８ａの位置から８ｂの
位置に下降するとその隙間はＧ、からＧｔに狭まる。In the figure, the mounting is configured such that the moving surface 3b of the base 9 and the surface of the plate spring 2 facing the electromagnet form a predetermined angle α (see also FIG. 2). With this configuration, the electromagnet 5
As the iron core 6 is lowered, the iron core 6 approaches the suction plate 7. That is, when mounting the moving surface 3b of the stand 9 as described above, the angle formed between the moving surface 11 of the iron core 6 and the suction plate 7 also becomes α, so that, for example, the axis of the iron core 6 is moved from the position 8a. When descending to position 8b, the gap narrows from G to Gt.
つまり電磁石５を下降させて振幅をより大きく増幅する
ようにするためにはより大きな振動エネルギーを必要と
するが、この振動エネルギーを隙間Ｇを狭めることによ
り達成するように構成している。That is, in order to lower the electromagnet 5 and amplify the amplitude to a greater extent, larger vibration energy is required, but this vibration energy is achieved by narrowing the gap G.
このように構成すれば粉粒体の種類や性情により最適な
振幅を設定することが可能となる。With this configuration, it becomes possible to set the optimum amplitude depending on the type and characteristics of the powder or granular material.

類や性情によって最適な振幅に調節することができる。As the configuration of the present invention has been specifically explained above, an electromagnet is disposed opposite to a plate spring that supports a powder arrangement part such as a hopper, and an electromagnet suction part of this plate spring and a powder By setting the distance between the particle mounting surface and the particle mounting surface to be large, the moment arm during vibration is set to be large, and in some cases, the electromagnet is also set so that it can be moved up and down along this leaf spring. Since the moment arm is configured to be variable, it is possible to obtain large-amplitude vibrations by amplifying the vibrations of a small electromagnet, which makes it possible to reduce the weight of the vibration feeder and to adjust the size of the powder and granular material. The amplitude can be adjusted to the optimum level depending on your personality and personality.
