Description

  The present invention relates to a vibratory component conveying apparatus in which a vibratory bowl feeder is connected to a vibratory linearly moving feeder.

  It is desirable that the vibration type component conveying apparatus that arranges and conveys minute electronic components and supplies them to the subsequent process is fixed on a highly rigid surface plate in order to fully exhibit the component supply capability. However, in practice, the vibratory parts conveying device is often fixed on an installation table provided on the floor surface. In this case, vibration from the vibration source is transmitted to the installation table and the installation table vibrates. When the reaction force of the vibration of the installation base is transmitted to the component conveying member, the vibration for supplying the component is hindered, and the component supply capability may not be fully exhibited. In addition, the vibration of the installation base is transmitted to the floor, affecting the operation of other equipment installed on the same floor, and conversely, the vibration of other equipment is transported through the installation base. It may be transmitted to the equipment and reduce the parts supply capacity.

  For this reason, normally, an anti-vibration member is provided between the installation base and the vibration type component conveying device to make it difficult for vibration to be transmitted between the two. For example, in Patent Documents 1 and 2, a vibration type linearly moving feeder of a type that supplies only parts in a desired posture to a subsequent process while conveying parts linearly in opposite directions with two troughs as parts conveying members. In the vibration component conveying apparatus provided, a drive spring support portion that supports a drive spring for vibrating the trough and an installation base fixed to the floor surface are connected by a plurality of leaf springs as vibration isolation members. Has been proposed.

  By the way, a vibration component conveying apparatus that aligns and supplies electronic components is often used in which a vibration type linear feeder and a vibration type bowl feeder connected to the upstream side thereof are fixed to one base. However, no technical guidelines have been established for the arrangement of the vibration isolating member provided between the base and the installation base for the vibratory component conveying apparatus in which the bowl feeder is connected to the linear feeder in this way. Furthermore, there is no description in the above Patent Documents 1 and 2. For this reason, depending on the installation position of the vibration isolating member, the linear feeder may cause yawing or pitching to lose balance, and the component supply may become unstable. In addition, the position change of the connecting part between the linear feeder and bowl feeder and the connecting part with the post process of the linear feeder becomes large, and parts are not delivered smoothly at the connecting part, and the parts supply capacity is reduced. There is also a risk.

  SUMMARY OF THE INVENTION Accordingly, the present invention provides a vibration component conveying apparatus in which a vibration-type bowl feeder is connected to a vibration-type linear feeder so that a vibration-proof effect by a vibration-proof member can be sufficiently obtained and stable parts can be supplied. And

  In order to solve the above problems, the present invention includes a vibration type linear feeder, a vibration type bowl feeder connected to the vibration type linear movement feeder, and a base on which the vibration type linear movement feeder and the vibration type bowl feeder are fixed. Equipped with a vibration-type component conveying device provided with a plurality of vibration isolation members between the base and the installation base fixed to the floor below the plurality of vibration isolation members when viewed from the vertical direction, Each installation position is a vertex of the polygon or a point on the side of the polygon, and the center of gravity of the vibration linear feeder, the vibratory bowl feeder and the base inside the polygon, and the vibration linear feeder alone The center of gravity was placed to fit.

Here, it is desirable that the anti-vibration rubber has a rubber hardness of 60 degrees or more as measured by a type A durometer of JIS K 6253. By using a vibration-proof rubber with high hardness, even if the load acting on the vibration-proof rubber changes, it is possible to suppress changes in the position of the connection part between the linear feeder and bowl feeder and the connection part with the subsequent process of the linear feeder. This is because the delivery of parts at the connecting portion can be performed smoothly.

  As described above, the vibration component conveying device of the present invention has a total gravity center of the vibration linear feeder, the vibration bowl feeder, and the base, and the gravity center of the vibration linear feeder alone as viewed from the vertical direction. Because it is designed to fit inside the polygon formed by the installation position of the vibration isolator, the vibration of the linear feeder can be suppressed in a well-balanced manner, making it difficult for yawing and pitching to occur, and stable parts can be supplied. it can.
