Description

  The present invention relates to a vibration-type component conveying device that conveys a component by using the vibration of another vibration device having an excitation mechanism.

  Vibrating component feeders such as vibratory bowl feeders and vibratory linear feeders used to transport and feed parts vibrate vibrating bodies such as bowls and troughs with their own vibration mechanisms, and are provided on this vibrating body. Parts are transported along the transport path. In addition, when parts are conveyed and supplied, it is often necessary to change the parts conveyance direction and conveyance speed in the middle of the conveyance path in order to align, sort, and maintain the parts. In this case, combine a plurality of vibratory parts conveyors each having a vibration mechanism to share the roles of alignment, sorting, posture maintenance, etc., and return parts that have been removed by sorting. (For example, refer to Patent Document 1).

  As the vibrating mechanism of the vibrating body, a mechanism using an electromagnetic force as a driving source using an electromagnet and a movable iron core, and a mechanism using a piezoelectric element as a driving source are often used. In addition to this, the vibration mechanism can be selected arbitrarily, such as a mechanically driven one or a fluid pressure driven one. In many cases, the energy consumed for driving the vibrating mechanism is large, and the running cost increases. In particular, when combining a plurality of vibratory component conveying devices, each is provided with a vibration mechanism, so that its energy consumption is considerably increased and the initial cost for installing the vibration mechanism is also increased.

  In order to reduce the number of vibration mechanisms installed by combining a plurality of vibratory component conveying devices, two troughs that extend linearly are arranged close to each other, and each trough is inclined in the opposite direction. It is supported by a leaf spring, an electromagnet is attached to one side, and a movable iron core facing this electromagnet is attached to the other, and these are caused to vibrate relative to each other in the opposite direction, and parts are conveyed in opposite directions by each trough (For example, refer to Patent Document 2).

  In addition, the vibrator that vibrates the transport body is provided with two sets of arm portions whose vibration phases are opposite to each other, and two transport bodies are separately attached to these arm portions, and the transported object is moved by each transport body. Some of them are transported in the opposite direction (see, for example, Patent Document 3).

JP 2000-118682 A (page 2-4, FIG. 1-2) JP 59-97912 (pages 3-4 and 3-4) JP-A-6-345238 (page 3-4, FIG. 5)

  Since the conventional vibration type component conveying devices that reduce the number of the above-described vibrating mechanisms are configured to vibrate the conveying bodies (troughs) directed in opposite directions with mutual interaction. , The amplitude of each individual carrier cannot be adjusted independently, and therefore the parts conveyance speed cannot be adjusted separately as in the case of combining a plurality of independent vibration type parts conveyance devices each having a vibration mechanism. There is. Also, the conveying direction of the components is limited to those opposite to each other.

  Accordingly, an object of the present invention is to reduce the number of vibration mechanisms installed in the vibration type component conveying apparatus and to increase the degree of freedom in setting the component conveying speed and direction.

In order to solve the above-described problems, the vibration type component conveying apparatus of the present invention is connected to the lower vibration body of the vibration type component conveying apparatus having an excitation mechanism by a plate spring inclined upward, and the plate spring is The same side as the leaf spring inclined in the upward direction that has a conveyance path for conveying components in the direction facing and is arranged at a vibration part that vibrates in a substantially horizontal direction with an interval in the vibration direction and connected to the lower vibration body to a plurality of leaf springs are inclined in the vertical plane, and the support towards the longitudinal direction at least one vibrator, the vibrations propagated through the plurality of leaf springs from the vibrating portion, the vibrating body A configuration is adopted in which the components are transported along the transport path provided in the front-rear direction to the side opposite to the transport path of the vibration part .

That is, it is connected to the lower vibrating body of the vibration type component conveying device having an excitation mechanism by a leaf spring inclined upward, and has a conveyance path for conveying the component in a direction in which the leaf spring faces, and in a substantially horizontal direction. the vibration part to vibrate, is arranged at an interval in the vibration direction, the a plurality of leaf springs which are inclined in a vertical plane on the same side as the leaf spring which is inclined supine connects the lower vibration member, at least one of The vibrating body is supported in the front-rear direction, and the component is moved along the conveying path provided in the front-rear direction of the vibrating body by vibration propagated from the vibrating section through the plurality of leaf springs. By moving toward the opposite side of the transfer path, the number of vibration mechanisms installed in the vibratory component transfer device can be reduced, and the degree of freedom in setting the transfer speed and transfer direction of the components can be increased. .

  By setting the front-rear direction of the vibrating body supported by the plurality of leaf springs to a direction within 45 ° in a horizontal plane with respect to the vibration direction of the vibrating portion, the component is moved along the conveyance path provided in the vibrating body. It can be transported stably. When the front-rear direction of the vibrating body with respect to the vibration direction of the vibration part exceeds 45 ° in the horizontal plane with respect to the vibration direction of the vibration part, the propagation of the vibration vector of the vibration part in the front-rear direction of the vibration body, which is the component transport direction This is because the component becomes smaller and the conveyance efficiency is lowered, and the torsional vibration of the leaf spring is increased.

  In addition, when making the front-back direction of the said vibrating body large within 45 degrees within a horizontal surface, it is good to increase each torsional rigidity by forming each leaf | plate spring wide. Further, the front-rear direction of the vibrating body, that is, the conveying direction of the components can be changed depending on the arrangement direction of the leaf springs in the horizontal plane. The conveying direction of the parts can also be changed by changing the mounting direction of the vibrating body in the horizontal plane.

  It is preferable that the inclination angle in the vertical plane of each leaf spring is within ± 45 ° with respect to the horizontal plane, and the relative inclination angle with each other is within 45 °. When the inclination angle in the vertical plane exceeds ± 45 ° with respect to the horizontal plane, the vibration vector component propagated from the vibration part increases in the plate thickness direction of the leaf spring having low rigidity, and the vibration of the vibrating body is reduced. It is small and unstable.

  Since the plate spring has a high rigidity in the longitudinal direction and a low rigidity in the plate thickness direction, the vibration vector in the substantially horizontal direction of the vibration part is a component facing the longitudinal direction of the leaf spring, that is, a component in the elevation angle direction of the leaf spring. Is propagated to the vibrating body. Therefore, as will be described later with reference to FIG. 3, by adjusting the inclination angle in the vertical plane of the leaf spring, the amplitude and vibration direction of the vibrating body are changed, and the conveying speed of the parts in the conveying path is increased. Can be adjusted.

  When two leaf springs arranged on the outermost side among the plurality of leaf springs are attached to the vibration part in a direction away from each other, it is suitable for a vibrating body that requires a relatively long conveyance path.

  When two leaf springs arranged on the outermost side among the plurality of leaf springs are attached to the vibration part in a direction close to each other, it is suitable for a vibrating body that requires a short partial conveyance path.

  By setting the center of gravity of the vibrating body on a substantially bisector of the interval between the leaf springs arranged on the outermost side among the plurality of leaf springs, the pitching of the vibrating body is prevented and the parts are stabilized. Can be transported.

  By forming at least one of the plurality of leaf springs by a pair of leaf spring units, and providing a crossing angle within the leaf surface between the two leaf springs of the leaf spring unit, The rigidity of the leaf spring that supports the vibrating body can be increased, and the vibration of the vibrating body can be further stabilized. In addition, the vibration of the vibrating portion that supports the vibrating body can also be stabilized. Moreover, even if the position of the center of gravity of the vibrating body is slightly deviated in the width direction, the posture can be stably maintained.

  A pair of leaf springs having a crossing angle in the plate surface are crossed with each other, so that the vibration parts at both ends of the pair of leaf springs and the attachment positions to the vibrating body are placed in the width direction. It is possible to prevent the rolling of the vibrating body by providing an interval.

  By providing the vibrating body with a weight whose mounting position can be adjusted, the center of gravity of the vibrating body can be easily adjusted.

  By making it possible to adjust the support position of the vibrating body to the vibrating site in the front-rear direction, the vibration balance between the vibrating body and the vibrating site can be adjusted.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 6 show a first embodiment. FIG. 1 shows a component supply device in which a vibration type bowl feeder 1 and a vibration type linear feeder 2 each having a vibration mechanism are combined with a vibration component conveying device 3 having no vibration mechanism according to the present invention. Show.

  The bowl feeder 1 torsionally vibrates the bowl 4 in the circumferential direction by a vibration mechanism (not shown) using an electromagnet and a movable iron core, and the parts put into the bottom of the bowl 4 are transferred to the spiral conveying path 5. Are aligned in a row at the narrow portion 5a of the conveyance path 5 and delivered to the trough 7 of the linear feeder 2 through the conveyance path 6a of the connecting member 6 connected to the outermost circumference conveyance path 5. . The bowl 4 is also provided with a return passage 8 that receives a part that is removed by a part selection unit 17 (to be described later) and returned and transported by the vibration part transporting device 3.

  As shown in FIGS. 1 and 2, the linear feeder 2 is attached to a lower vibrating body 10 and an upper vibrating body 11 connected by a pair of parallel leaf springs 9 with an electromagnet 12 and a movable iron core 13 facing each other, The trough 7 attached to the upper vibrating body 11 is reciprocally oscillated, and the parts are conveyed along the straight conveying path 16 in a direction in which the pair of leaf springs 9 face up. Further, the lower vibrating body 10 is provided with a counterweight 10a and is attached to the base 15 via an anti-vibration spring 14. The upper vibrating body 11 has a leaf spring 20 of the vibration type component conveying device 3 to be described later. A connecting member 11a to which is attached is provided.

  The parts delivered to the trough 7 are conveyed along the straight conveyance path 16 to the right side where the leaf spring 9 faces upward, and the parts sorting unit 17 provided in the middle of the conveyance path 16 causes a posture error. Things are removed in the groove 18 on the side of the conveying path 16, and only parts in a predetermined posture are supplied to the discharge end 19.

  The vibration-type component conveying device 3 is arranged in parallel with the connecting member 11a of the upper vibrating body 11 that reciprocally vibrates with an equal inclination angle in the vertical plane in the direction parallel to the vibration direction in the horizontal plane. The vibrating body 22 provided with the straight conveyance path 21 is supported by the two leaf springs 20. Each leaf spring 20 is attached to the connecting member 11a of the upper vibrating body 11 facing upward and in the same left direction. As will be described later with reference to FIG. Transport. Further, the vibrating body 22 is provided with a weight 23, and the attachment position thereof can be adjusted in the front-rear direction at the position where the bolt 24b is locked to the long hole 24a.

  The vibration body 22 receives the vibration of the upper vibration body 11 through the two leaf springs 20 and receives the part having the poor posture discharged from the groove 18 of the trough 7 on the upstream side of the conveyance path 21. Then, from the downstream side to the return passage 8 of the bowl 4, it is returned and conveyed in the direction opposite to the conveying direction of the linear feeder 2. A slight climbing gradient is given to the conveyance path 21 of the vibrating body 22 due to the height difference between the bowl feeder 1 and the linear feeder 2, but the leaf spring 20 of the vibrating body 22 described later in the elevation angle direction is provided. Due to the vibration, the parts are returned to the climbing slope without any problem.

Hereinafter, the vibration form transmitted to the vibrating body 22 will be described with reference to FIG. The inclination angle of the vibration vector V of the upper vibrating body 11 in the vertical plane is β (in the example of FIG. 3, the vibration vector V is slightly downward, so β in this case is negative), and each parallel. Assuming that the inclination angle in the vertical plane of the leaf spring 20 is α, the magnitude of the component V _L of the vibration vector V facing the longitudinal direction of the leaf spring 20 is V · cos (α−β), and the leaf thickness of the leaf spring 20 The magnitude of the component V _T that faces the direction is V · sin (α−β). Since the plate spring 20 has a high rigidity in the longitudinal direction and a low rigidity in the plate thickness direction, the vibration vector V of the upper vibrating body 11 is a component V _L that faces the longitudinal direction of the plate spring 20, that is, the inclination angle of the plate spring 20. An amplitude having a direction of α and a size of V · cos (α−β) is propagated to the vibrating body 22 via each leaf spring 20.

  The center of gravity G of the vibrating body 22 is set on a bisector L of a distance D between two parallel leaf springs 20 by adjusting the attachment position of the weight 23. Therefore, the vibrating body 22 vibrates with an amplitude of V · cos (α−β) in the direction of the inclination angle α of the leaf spring 20 without causing pitching, and transports the component A back along the transport path 21. Since this amplitude is a monotonically decreasing function of α in the range of β ≦ α ≦ 90 °, adjusting the inclination angle α of the leaf spring 20 in this range allows the amplitude of the vibrating body 22, that is, the conveying speed u of the component A. Can be adjusted. Practically, it is preferable to set the inclination angle α of the leaf spring 20 to about 45 ° or less. When the distance D between the two leaf springs 20 is 0, that is, when the two leaf springs 20 are arranged on a straight line, the center of gravity G of the vibrating body 22 may be set on this straight line.

As shown in FIG. 4, the linear feeder 2 is driven at a frequency F _D close to the natural frequency F _N2 of the vibration system, vibrating component transporting apparatus 3 which is formed with the vibrating body 22 by the plate spring 20 The natural frequency F _N3 of the vibration system is set to be sufficiently smaller than the drive frequency F _D of the linear feeder 2. Accordingly, the driving frequency F amplitude of the V _T direction of vibratory parts conveying apparatus 3 in _D becomes sufficiently small, without resonating in the thickness direction of the low rigidity plate spring 20, the vibrator 22 is V · cos ( It vibrates stably with an amplitude of α−β).

  FIG. 5 shows a modification of the method for attaching the weight 23 to the vibrating body 22. The mounting position of the weight 23 is a locking position by a set screw 25b to the mounting bracket 25a, and can be adjusted in the vertical direction.

In addition, the conveyance direction of the components in the conveyance path 21 of the vibrating body 22 in each schematic diagram is in the opposite direction (leftward direction) to the conveyance direction of the rectilinear feeder 2.

  FIG. 6A is an example in which two leaf springs 20 are attached to the upper vibrating body 11 in a direction away from each other with one facing upward and the other facing downward, and a relatively long conveying path 21 is required. This is suitable for the vibrating body 22. FIG. 6B shows an example in which two leaf springs 20 are mounted in a direction close to each other with one facing upward and the other facing downward, and a vibrating body 22 that requires a short partial conveyance path 21.
