Abstract

PROBLEM TO BE SOLVED: To provide a lightweight vibrating feeder capable of reducing projections of a driving device from a trough, and suppressing breakage of a coil in the driving device.SOLUTION: A trough 10 includes a trough body 11 for feeding an object to be conveyed, and a pair of lower side plates 13 mounted on a lower side of the trough body 11. A driving device 20 is arranged on the inner sides of the pair of lower side plates 13. The driving device 20 includes a fixed core-side driving unit 30 mounted on the trough 10, and a movable core-side driving unit 50 connected to the fixed core-side driving unit 30 via a leaf spring 40. The fixed core-side driving unit 30 has a coil.

Description

本発明は、電磁式の駆動装置を備える振動フィーダに関する。   The present invention relates to a vibration feeder including an electromagnetic drive device.

従来より、トラフと、トラフを振動させる電磁式の駆動装置とを備える振動フィーダが知られている（例えば特許文献１）。従来の振動フィーダは、トラフから出っ張るように駆動装置が配置される構造であった。   Conventionally, a vibration feeder including a trough and an electromagnetic driving device that vibrates the trough is known (for example, Patent Document 1). The conventional vibration feeder has a structure in which a driving device is arranged so as to protrude from the trough.

また、従来の振動フィーダは、トラフの質量に対して駆動装置の質量が大きく設定されていた（例えばトラフの質量：駆動装置の質量＝１：２など）。ここで、トラフと駆動装置との振幅比は、これらの質量比の逆比となる。すなわち、従来の振動フィーダでは、トラフの振幅に対して駆動装置の振幅が小さく設定されていた（例えばトラフの振幅：駆動装置の振幅＝２：１など）。   Further, in the conventional vibration feeder, the mass of the driving device is set to be larger than the mass of the trough (for example, the mass of the trough: the mass of the driving device = 1: 2). Here, the amplitude ratio between the trough and the drive device is an inverse ratio of these mass ratios. That is, in the conventional vibration feeder, the amplitude of the driving device is set to be smaller than the amplitude of the trough (for example, the amplitude of the trough: the amplitude of the driving device = 2: 1).

特開昭６１−２０８２６号公報Japanese Patent Laid-Open No. 61-20826

しかしながら、上記の振動フィーダには次の課題があった。   However, the above vibration feeder has the following problems.

まず、従来の振動フィーダでは、トラフから出っ張るように駆動装置が配置される構造であったため、振動フィーダの小型化が望まれていた。   First, since the conventional vibration feeder has a structure in which the drive device is arranged so as to protrude from the trough, it is desired to reduce the size of the vibration feeder.

また、振動フィーダの軽量化も望まれていた。ここで、トラフを軽くすることは強度上困難である。よって、駆動装置を軽くすることが考えられる。しかしながら、トラフの質量に対する駆動装置の質量を小さくすると、トラフの振幅に対する駆動装置の振幅が大きくなる（例えばトラフの振幅：駆動装置の振幅＝１：２など）。これにより、駆動装置内のコイルが破損する問題が生じる。この問題が振動フィーダの軽量化を阻害していた。   In addition, weight reduction of the vibration feeder has been desired. Here, it is difficult in terms of strength to reduce the trough. Therefore, it is conceivable to reduce the driving device. However, if the mass of the driving device relative to the trough mass is reduced, the amplitude of the driving device relative to the trough amplitude increases (for example, trough amplitude: drive device amplitude = 1: 2). This causes a problem that the coil in the driving device is damaged. This problem hinders weight reduction of the vibration feeder.

本発明の目的は、トラフからの駆動装置の出っ張りを減らすことができ、駆動装置内のコイルの破損を抑制でき、軽量に構成できる振動フィーダを提供することである。   The objective of this invention is providing the vibration feeder which can reduce the protrusion of the drive device from a trough, can suppress the failure | damage of the coil in a drive device, and can be comprised lightweight.

本発明に係る振動フィーダは、トラフと、当該トラフを振動させる駆動装置と、を備える。前記トラフは、被搬送体を給送するトラフ本体と、前記トラフ本体の下方側に取り付けられる一対の下部側板と、を備える。前記駆動装置は、一対の前記下部側板の内側に配置される装置であって、前記トラフに取り付けられる固定コア側駆動部と、前記固定コア側駆動部に板バネを介して連結される可動コア側駆動部と、を備える。前記固定コア側駆動部は、コイルが取り付けられる固定コアを備える。前記可動コア側駆動部は、前記固定コアと前記コイルとで構成される電磁石により当該固定コア側に吸引される可動コアを備える。   The vibration feeder according to the present invention includes a trough and a drive device that vibrates the trough. The trough includes a trough body that feeds a transported body, and a pair of lower side plates that are attached to the lower side of the trough body. The drive device is a device arranged inside a pair of lower side plates, and a fixed core side drive unit attached to the trough, and a movable core connected to the fixed core side drive unit via a leaf spring A side drive unit. The fixed core side drive unit includes a fixed core to which a coil is attached. The said movable core side drive part is provided with the movable core attracted | sucked to the said fixed core side by the electromagnet comprised with the said fixed core and the said coil.

この振動フィーダでは、駆動装置は、トラフを構成する一対の下部側板の内側に配置される。したがって、一対の下部側板の内側に駆動装置が配置されない場合に比べ、トラフからの駆動装置の出っ張りを減らすことができる。   In this vibration feeder, the drive device is disposed inside the pair of lower side plates that constitute the trough. Therefore, the protrusion of the drive device from the trough can be reduced as compared with the case where the drive device is not disposed inside the pair of lower side plates.

また、この振動フィーダの駆動装置は、トラフに取り付けられる固定コア側駆動部と、この固定コア側駆動部に板バネを介して連結される可動コア側駆動部と、を備える。すなわち、この振動フィーダは、トラフ及び固定コア側駆動部を備える一の質量部と、可動コア側駆動部を備える他の質量部と、が板バネで連結された２質量振動系を構成する。一般にこのような振動系では、２つの質量部の質量比と振幅比とが逆比の関係となる。
また、この振動フィーダでは、固定コア側駆動部は、コイルが取り付けられる固定コアを備える。また、可動コア側駆動部は、固定コアとコイルとで構成される電磁石により固定コア側に吸引される可動コアを備える。この構成により、可動コア側駆動部にはコイルを設ける必要がない。
ここで、一の質量部に対する可動コア側駆動部の質量を軽くすると、一の質量部に対する可動コア側駆動部の振幅は大きくなる。この振幅の大きい可動コア側駆動部にコイルが取り付けられれば、コイルが破損するという問題が生じ得る。しかしながら、この振動フィーダでは、可動コア側駆動部にはコイルを設ける必要がないので、上記のコイル破損の問題をなくすことができる。したがって、可動コア側駆動部を軽量に構成できる。その結果、振動フィーダを軽量に構成できる。 The drive device for the vibration feeder includes a fixed core side drive unit attached to the trough, and a movable core side drive unit coupled to the fixed core side drive unit via a leaf spring. That is, this vibration feeder constitutes a two-mass vibration system in which one mass part including a trough and a fixed core side driving unit and another mass unit including a movable core side driving unit are connected by a leaf spring. In general, in such a vibration system, the mass ratio and the amplitude ratio of two mass parts are in an inverse ratio relationship.
Moreover, in this vibration feeder, the fixed core side drive unit includes a fixed core to which a coil is attached. Moreover, the movable core side drive part is provided with the movable core attracted | sucked to the fixed core side by the electromagnet comprised with a fixed core and a coil. With this configuration, it is not necessary to provide a coil in the movable core side drive unit.
Here, if the mass of the movable core side drive unit with respect to one mass unit is reduced, the amplitude of the movable core side drive unit with respect to one mass unit increases. If the coil is attached to the movable core side drive unit having a large amplitude, there may be a problem that the coil is damaged. However, in this vibration feeder, since there is no need to provide a coil in the movable core side drive unit, the above-described problem of coil breakage can be eliminated. Therefore, the movable core side drive unit can be configured to be lightweight. As a result, the vibration feeder can be configured to be lightweight.

以上の説明に述べたように、特に、一対の下部側板の内側に駆動装置が配置される構成により、トラフからの駆動装置の出っ張りを減らすことができる。また特に、トラフに取り付けられる固定コア側駆動部にコイルが取り付けられる構成により、可動コア側駆動部にコイルを設ける必要がないので、可動コア側駆動部を軽量に構成でき、その結果、振動フィーダを軽量に構成できる。   As described in the above description, the protrusion of the drive device from the trough can be reduced particularly by the configuration in which the drive device is arranged inside the pair of lower side plates. In particular, since the coil is attached to the fixed core side drive part attached to the trough, it is not necessary to provide the coil in the movable core side drive part, so that the movable core side drive part can be configured to be lightweight, and as a result, the vibration feeder Can be made lightweight.

Hereinafter, the configuration of the vibration feeder 1 will be described in detail with reference to FIGS.

振動フィーダ１は、材料、食品、機械、部品、その他の被搬送物を搬送する吊り下げ式電磁式直進フィーダである。この振動フィーダ１は、図１及び図２に示すように、トラフ１０と、トラフ１０を振動させる駆動装置２０と、を備える。なお、駆動装置２０が振動する方向をＹ方向という。   The vibration feeder 1 is a suspended electromagnetic linear feeder that conveys materials, food, machines, parts, and other objects to be conveyed. As shown in FIGS. 1 and 2, the vibration feeder 1 includes a trough 10 and a driving device 20 that vibrates the trough 10. The direction in which the drive device 20 vibrates is referred to as the Y direction.

トラフ１０は、駆動装置２０により直線方向（Ｙ方向）に振動させられる部分である。このトラフ１０は、トラフ本体１１と、トラフ本体１１の下部に取り付けられる一対の下部側板１３と、一対の下部側板１３の間に取り付けられる結合部１５（図１参照）とを備える。   The trough 10 is a portion that is vibrated in the linear direction (Y direction) by the driving device 20. The trough 10 includes a trough body 11, a pair of lower side plates 13 attached to a lower portion of the trough body 11, and a coupling portion 15 (see FIG. 1) attached between the pair of lower side plates 13.

トラフ本体１１は、被搬送体を給送する桶状部材である。このトラフ本体１１の外側には複数のフック１１ｆが取り付けられる。   The trough body 11 is a bowl-shaped member that feeds the transported body. A plurality of hooks 11 f are attached to the outside of the trough body 11.

フック１１ｆには、図示しない吊下装置が取り付けられる。これにより振動フィーダ１が天井等に吊り下げられる。   A hanging device (not shown) is attached to the hook 11f. Thereby, the vibration feeder 1 is suspended from the ceiling or the like.

下部側板１３は、駆動装置２０を覆う一対の板であり、トラフ本体１１の下方側に取り付けられる。一対の下部側板１３は、内側に駆動装置２０を配置できるように配置される。具体的には例えば、図１に示すように、トラフ本体１１の幅方向の両端部から下方側に延びるように間隔をあけて配置される。なお、一対の下部側板１３が対向する方向をＸ方向という。また、図１及び図２に示すように、一対の下部側板１３は、駆動装置２０全体を内側に配置できるように（駆動装置２０全体を覆えるように）形成されることが好ましい。具体的には例えば、駆動装置２０の下端部にほぼ沿うように下部側板１３の下辺１３ａが形成される。また、一対の下部側板１３の下辺１３ａ及び後辺１３ｂにはカバー１４（図２参照）が取り付けられる。   The lower side plates 13 are a pair of plates that cover the drive device 20 and are attached to the lower side of the trough body 11. The pair of lower side plates 13 are arranged so that the driving device 20 can be arranged inside. Specifically, for example, as shown in FIG. 1, the trough main body 11 is disposed with a gap so as to extend downward from both ends in the width direction. The direction in which the pair of lower side plates 13 oppose is referred to as the X direction. Further, as shown in FIGS. 1 and 2, the pair of lower side plates 13 are preferably formed so that the entire driving device 20 can be disposed inside (so as to cover the entire driving device 20). Specifically, for example, the lower side 13 a of the lower side plate 13 is formed so as to be substantially along the lower end portion of the driving device 20. A cover 14 (see FIG. 2) is attached to the lower side 13a and the rear side 13b of the pair of lower side plates 13.

カバー１４（図２参照）は駆動装置２０を覆う板である。カバー１４は、一対の下部側板１３それぞれの下辺１３ａ及び後辺１３ｂを連結するように、一対の下部側板１３に取り付けられる。なお、図１ではカバー１４を一対の下部側板１３から取り外した状態を示している。   The cover 14 (see FIG. 2) is a plate that covers the drive device 20. The cover 14 is attached to the pair of lower side plates 13 so as to connect the lower side 13 a and the rear side 13 b of each of the pair of lower side plates 13. FIG. 1 shows a state where the cover 14 is removed from the pair of lower side plates 13.

結合部１５は、図１に示すように、トラフ１０と駆動装置２０とを結合する部材である。結合部１５は、結合板１５ａ及び結合板１５ｂを備える。   As shown in FIG. 1, the coupling portion 15 is a member that couples the trough 10 and the driving device 20. The coupling unit 15 includes a coupling plate 15a and a coupling plate 15b.

結合板１５ａは、一対の下部側板１３に取り付けられるとともに、駆動装置２０（固定コア側駆動部３０）が取り付けられる板である。結合板１５ａは、一対の下部側板１３を連結するように、一対の下部側板１３に取り付けられる。これにより一対の下部側板１３を補強できる。   The coupling plate 15a is a plate that is attached to the pair of lower side plates 13 and to which the drive device 20 (fixed core side drive unit 30) is attached. The coupling plate 15 a is attached to the pair of lower side plates 13 so as to connect the pair of lower side plates 13. Thereby, a pair of lower side board 13 can be reinforced.

結合板１５ｂは、トラフ本体１１の底面と結合板１５ａとを連結する板である。結合板１５ｂは、トラフ本体１１の底面及び結合板１５ａそれぞれに垂直に取り付けられる。これにより、駆動装置２０の振動がトラフ本体１１に確実に伝わる。   The coupling plate 15b is a plate that connects the bottom surface of the trough body 11 and the coupling plate 15a. The coupling plate 15b is vertically attached to the bottom surface of the trough body 11 and the coupling plate 15a. Thereby, the vibration of the drive device 20 is reliably transmitted to the trough body 11.

（駆動装置）
駆動装置２０は、図１及び図２に示すように、トラフ１０を振動させる装置であり、電磁石で駆動する。駆動装置２０は、一対の下部側板１３の内側に配置される。すなわち、トラフ１０から駆動装置２０が出っ張っていない。言い換えれば、駆動装置２０はトラフ１０に内蔵されている。なお、駆動装置２０全体を一対の下部側板１３の内側に配置することが好ましい。この配置により、振動フィーダ１をより小型化できる。 (Driver)
As shown in FIGS. 1 and 2, the drive device 20 is a device that vibrates the trough 10, and is driven by an electromagnet. The driving device 20 is disposed inside the pair of lower side plates 13.

The two fixed core side support portions 31 are separated from the fixed core side support portion main body 31a and the fixed core side support portion main body 31a, respectively, including the trough attachment portion 31t and the fixed core attachment portion 31c in order from the Y1 side to the Y2 side. And a leaf spring retainer 31s provided on the body.

A connecting plate 15a of the connecting portion 15 of the trough 10 is attached to the trough attaching portion 31t, and is fixed with, for example, a bolt 32t.

固定コア取付部３１ｃは、図３に示すように、固定コア３３を取り付ける部分である。２つの固定コア側支持部３１それぞれの固定コア取付部３１ｃは、固定コア３３を挟むように配置され、例えばボルト３２ｃを用いて固定コア３３を固定する。   As shown in FIG. 3, the fixed core attachment portion 31 c is a portion to which the fixed core 33 is attached. The fixed core attachment portions 31c of the two fixed core side support portions 31 are arranged so as to sandwich the fixed core 33, and fix the fixed core 33 using, for example, bolts 32c.

板バネ押さえ３１ｓは、トラフ取付部３１ｔ及び固定コア取付部３１ｃを備える固定コア側支持部本体３１ａとは別体に設けられる。そして固定コア側支持部本体３１ａと板バネ押さえ３１ｓとで板バネ４０のＸ方向両端部を挟み、例えばボルト３２ｓで固定する。   The leaf spring retainer 31s is provided separately from the fixed core side support body 31a including the trough attachment portion 31t and the fixed core attachment portion 31c.

（振動フィーダの動作）
次に、図１及び図２に示す振動フィーダ１の動作について説明する。振動フィーダ１では、２つの重りがバネで連結された２質量振動系が構成される。すなわち、図４に示すように、固定コア側駆動部３０及びトラフ１０を備える一の質量部Ｍ１と、可動コア側駆動部５０を備える他の質量部Ｍ２と、一の質量部Ｍ１と他の質量部Ｍ２とを連結する板バネ４０とで２質量振動系が構成される。 (Vibration feeder operation)
Next, the operation of the vibration feeder 1 shown in FIGS. 1 and 2 will be described. In the vibration feeder 1, a two-mass vibration system in which two weights are connected by a spring is configured. That is, as shown in FIG. 4, one mass unit M1 including the fixed core side drive unit 30 and the trough 10, another mass unit M2 including the movable core side drive unit 50, one mass unit M1, and other A two-mass vibration system is configured by the leaf spring 40 connecting the mass part M2.

図３に示すコイル３５へ電流を周期的に流すと、固定コア３３とコイル３５とで構成される電磁石と、可動コア５３との間で電磁力が周期的に発生する。そして図４に示す一の質量部Ｍ１と他の質量部Ｍ２とが、図３に示す固定コア３３と可動コア５３とが対向する方向（Ｙ方向）に振動する。   When a current is periodically passed through the coil 35 shown in FIG. 3, an electromagnetic force is periodically generated between the electromagnet composed of the fixed core 33 and the coil 35 and the movable core 53. And one mass part M1 shown in FIG. 4 and the other mass part M2 vibrate in the direction (Y direction) where the fixed core 33 and the movable core 53 shown in FIG. 3 face each other.

ここで、図４に示す一の質量部Ｍ１と他の質量部Ｍ２との振幅比は、これらの質量比の逆比となる。具体的には例えば、一の質量部Ｍ１の質量：他の質量部Ｍ２の質量＝２：１、に設定すれば、一の質量部Ｍ１の振幅：他の質量部Ｍ２の振幅＝１：２となる。   Here, the amplitude ratio between one mass part M1 and the other mass part M2 shown in FIG. 4 is an inverse ratio of these mass ratios. Specifically, for example, if the mass of one mass part M1: the mass of another mass part M2 = 2: 1, the amplitude of one mass part M1: the amplitude of another mass part M2 = 1: 2. It becomes.

（本実施形態の振動フィーダの特徴）
本実施形態の振動フィーダ１には以下の特徴がある。 (Characteristics of the vibration feeder of this embodiment)
The vibration feeder 1 of the present embodiment has the following features.

（特徴１）
振動フィーダ１では、図１及び図２に示すように、トラフ１０を構成する一対の下部側板１３の内側に駆動装置２０が配置される。すなわち駆動装置２０はトラフ１０に内蔵される。したがって、一対の下部側板１３の内側に駆動装置２０が配置されない場合に比べ、トラフ１０からの駆動装置２０の出っ張りを減らすことができる。 (Feature 1)
In the vibration feeder 1, as shown in FIGS. 1 and 2, the driving device 20 is disposed inside the pair of lower side plates 13 that constitute the trough 10. That is, the driving device 20 is built in the trough 10. Therefore, the protrusion of the drive device 20 from the trough 10 can be reduced as compared with the case where the drive device 20 is not disposed inside the pair of lower side plates 13.

（特徴２）
また、振動フィーダ１の駆動装置２０は、トラフ１０に取り付けられる固定コア側駆動部３０と、この固定コア側駆動部３０に板バネ４０を介して連結される可動コア側駆動部５０と、を備える。すなわち、図４に示すように、この振動フィーダ１は、トラフ１０及び固定コア側駆動部３０を備える一の質量部Ｍ１と、可動コア側駆動部５０を備える他の質量部Ｍ２と、が板バネ４０で連結された２質量振動系を構成する。一般にこのような振動系では、２つの質量部の質量比と振幅比とが逆比の関係となる。 (Feature 2)
The driving device 20 of the vibration feeder 1 includes a fixed core side drive unit 30 attached to the trough 10 and a movable core side drive unit 50 connected to the fixed core side drive unit 30 via a leaf spring 40. Prepare. That is, as shown in FIG. 4, the vibration feeder 1 includes a trough 10 and one mass part M1 including the fixed core side drive unit 30 and another mass part M2 including the movable core side drive unit 50. A two-mass vibration system connected by a spring 40 is configured. In general, in such a vibration system, the mass ratio and the amplitude ratio of two mass parts are in an inverse ratio relationship.

また、この振動フィーダ１では、図３に示すように、固定コア側駆動部３０は、コイル３５が取り付けられる固定コア３３を備える。また、可動コア側駆動部５０は、固定コア３３とコイル３５とで構成される電磁石により固定コア３３側（Ｙ１側）に吸引される可動コア５３を備える。この構成により、可動コア側駆動部５０にはコイル３５を設ける必要がない。   Moreover, in this vibration feeder 1, as shown in FIG. 3, the fixed core side drive part 30 is provided with the fixed core 33 to which the coil 35 is attached. In addition, the movable core side drive unit 50 includes a movable core 53 that is attracted to the fixed core 33 side (Y1 side) by an electromagnet composed of the fixed core 33 and the coil 35. With this configuration, it is not necessary to provide the coil 35 in the movable core side drive unit 50.

ここで、図４に示す一の質量部Ｍ１に対する他の質量部Ｍ２（可動コア側駆動部５０）の質量を軽くすると、一の質量部Ｍ１に対する他の質量部Ｍ２（可動コア側駆動部５０）の振幅は大きくなる。この振幅の大きい可動コア側駆動部５０にコイルが取り付けられていれば、コイル３５が破損するという問題が生じ得る。しかしながら、この振動フィーダ１では、可動コア側駆動部５０にはコイルを設ける必要がないので、上記のコイル破損の問題をなくすことができる。したがって、可動コア側駆動部５０を軽量に構成できる。その結果、振動フィーダ１を軽量に構成できる。   Here, if the mass of the other mass part M2 (movable core side drive part 50) with respect to one mass part M1 shown in FIG. 4 is lightened, the other mass part M2 with respect to one mass part M1 (movable core side drive part 50). ) Becomes larger. If a coil is attached to the movable core side drive unit 50 having a large amplitude, there may be a problem that the coil 35 is damaged. However, in this vibration feeder 1, since it is not necessary to provide a coil in the movable core side drive part 50, the problem of said coil breakage can be eliminated. Therefore, the movable core side drive part 50 can be comprised lightweight. As a result, the vibration feeder 1 can be configured to be lightweight.

以上、本発明の実施形態について図面に基づいて説明したが、具体的な構成はこれらの実施の形態に限られるものではなく、発明の要旨を逸脱しない範囲で変更可能である。   As mentioned above, although embodiment of this invention was described based on drawing, a specific structure is not restricted to these embodiment, It can change in the range which does not deviate from the summary of invention.

例えば、前記実施形態では、振動フィーダ１を吊り下げ式としたが、振動フィーダ１を地面に設置しても本発明を適用できる。この場合は例えば、地面に支持台（図示なし）を設置し、支持台の上にバネ（図示なし）を介して振動フィーダ１を載せる。   For example, in the embodiment, the vibration feeder 1 is a suspension type, but the present invention can be applied even if the vibration feeder 1 is installed on the ground. In this case, for example, a support base (not shown) is installed on the ground, and the vibration feeder 1 is placed on the support base via a spring (not shown).
