Description

Vibrating parts conveying device

The present invention relates to a vibrating component transporting apparatus that vibrates a component transporting member having a linear transport path and transports the components on the transport path.

As a device that transports components such as electronic chip components by vibration, and arranges the components to be aligned (the posture of the components is matched) and supplies them to the next step, a vibrating component transfer device is often used. The upstream side of the vibrating straight feeder which is capable of adjusting the component supply speed along the chute which is conveyed by the linear conveying path, and the disk having the spiral conveying path is connected and the parts can be stored in a large amount. Vibrating bowl feeder.

In the vibrating parts conveying device that connects the bowl feeder and the straight feeding feeder as described above, in general, since the vibration directions, vibration frequencies, and amplitudes of the two feeders are different, it is necessary to The conveying path of the bowl feeder is provided to the component delivery portion between the conveying paths of the straight feeding feeder, and a gap is provided between the conveying paths, and the gap is likely to be blocked or jammed. Therefore, in the part intersection, the conveying path of the straight feeder is set to be lower than that of the bowl feeder, so that the parts can be smoothly transferred. However, when there is a gap between the conveying paths of the parts intersections, even if the parts are arranged neatly in the bowl feeder, the parts may change their posture due to the impact when they are transferred to the straight feeder. Or situations where parts overlap each other.

On the other hand, in the following Patent Document 1, it has been proposed to provide a vibrating straight feed. The inlet portion of the conveying path of the feeder is set to the R groove, and the degree of freedom of the behavior of the parts is increased, so that the parts which are in a state of being overlapped or arranged in two rows are easily arranged one by one.

However, in a general vibrating straight-feed feeder, an arrangement transporting unit that transports parts that are transported from the upstream side is often provided in the middle of the transport path of the component transport member such as the chute. Correct the position of the part or remove the part with poor posture. In this case, even if the part from the entrance of the conveyance path to the arrangement conveyance part is an R groove as described in the above-mentioned Patent Document 1, it is easy to arrange the parts one by one, but still based on FIG. 4(a) below. ~(c) and as shown in Figs. 5(a) to (d), the shape of the entrance of the R-slot and the arranging and conveying portion is different, and the components are changed in posture or overlapped with each other due to the step.

4(a) to 4(c) and 5(a) show the entrance of the chute 51 from the linear transport path 52 in the vibrating straight feeder which performs the arrangement and transport of the rectangular parallelepiped parts P ( The portion to the arrangement transport portion 53 is a main portion of the example of the R groove 54. The arrangement transport unit 53 of the transport path 52 passes only the component P in the longitudinal direction of the transport direction (hereinafter, this posture is referred to as "good posture"), and the posture is poor (the longitudinal direction is oriented toward the transport path width direction). The part P of the posture with the longitudinal direction upward is dropped to the collecting portion 55, and is removed from the conveying path 52. On the other hand, the bottom portion (the central portion in the width direction) of the R groove 54 is formed to be slightly higher than the conveyance surface 53a of the array conveyance portion 53.

The plurality of parts P on the R groove 54 of the chute 51 are conveyed in a good posture by the semicircular cross-sectional shape of the R groove 54, and are transferred from the bottom to the array conveying portion 53, but There are also cases where a part of the part P changes posture in the middle of the R groove 54. In the case of a good posture, it is swayed in the width direction of the conveyance path 52, and the slope of either side of the slope which is higher than the bottom of the R groove 54 is transferred to the arrangement conveyance portion 53.

Then, the part P which has been transferred from the bottom of the R groove 54 to the arranging and conveying unit 53 is conveyed in a good posture as shown in Fig. 5(b) because the difference in the transition is small. On the other hand, since the component P which has been transferred from the inclined surface of the R groove 54 to the aligning and conveying portion 53 has a large difference in the transition, the posture of the side wall 53b of the arranging and conveying portion 53 rises as shown in Fig. 5(c). As shown in FIG. 5(d), the longitudinal direction is rotated in the longitudinal direction of the transport path to cause a posture failure. Further, although not shown in the drawings, there are cases where the subsequent component P is mounted on the preceding component P. When the components P that have changed their postures or overlap each other when they are arranged in the transporting portion 53 are thus dropped to the collecting portion 55, they are excluded, or the portions on the downstream side which are not shown are excluded, resulting in parts of the straight feed feeder. The supply capacity is reduced.

Therefore, an object of the present invention is to improve the component supply capability in a vibrating component transport apparatus in which an R-slot is provided on the upstream side of the transport path of the component transport member that linearly transports the component.

In order to solve the above problem, the present invention provides a vibrating component conveying apparatus including a component conveying member that conveys a component along a linear conveying path, and an R groove is provided on the upstream side of the conveying path of the component conveying member, and is disposed on the downstream side. The portion in which the cross-sectional shape is different from the R-groove is arranged, and the portion from the outlet of the R-groove of the transport path to the entrance of the transporting portion is smoothly changed from the shape of the R-groove in the component transport direction to the component transport direction. The shape converting portion of the inlet shape of the conveying portion is arranged as described above. According to this configuration, the sharp drop between the outlet of the R groove of the transport path and the entrance of the arranging and transporting portion disappears, and the component that is in a good posture in the R groove is transferred to the arranging and transporting portion, and the posture change is less likely to occur. The part supply capability can be improved as compared with the case where the outlet of the R groove is directly connected to the inlet of the arrangement conveyance unit.

In the above configuration, the length of the shape conversion portion of the transport path is set The shape conversion portion of the transport path is inclined downward from the outlet of the R-slot toward the entrance of the arranging and transporting portion, so that the component can smoothly pass through the shape-converting portion. The inclination angle when the shape conversion portion of the transport path is inclined is preferably 2 to 5 degrees.

Further, when the connection between the R groove and the shape conversion portion of the conveyance path is chamfered, the transfer from the R groove to the component of the shape conversion portion is also smooth.

As described above, the vibrating component conveying device of the present invention is provided between the R groove on the upstream side of the linear conveying path and the arranging conveying portion on the downstream side, and the cross-sectional shape is smoothly changed from the shape of the R groove in the component conveying direction. In order to arrange the shape conversion portion of the inlet shape of the conveying portion, the sharp drop between the outlet of the R groove and the inlet of the arranging and conveying portion is eliminated. Therefore, when the component that is in a good posture in the R groove is transferred to the arranging conveying portion, the posture change is less likely to occur. It is also possible to improve the supply of parts.

Hereinafter, embodiments of the present invention will be described based on Figs. 1 to 3(a) to (d). The vibrating component conveying device arranges and transports the rectangular parallelepiped parts P, as shown in FIG. As shown, the vibrating bowl feeder 1 and the vibrating straight feeder 11 connected to the downstream side thereof are provided. Further, by vibrating the bowl 2 of the bowl feeder 1, the part P placed at the bottom of the bowl 2 is conveyed by the spiral conveying path 3, and the part P is delivered to the straight feeder 11 from the outlet thereof. The inlet of the linear transport path 13 of the chute (part transport member) 12 is caused to vibrate the chute 12 of the straight feed machine 11, and the component P on the transport path 13 of the chute 12 is linearly transported and supplied to The next step.

In the above-described bowl-shaped feeder 1 , the component P is conveyed by the spiral conveyance path 3, and the conveyance path 13 is supplied to the chute 12 in a line by one line. On the other hand, the straight feed machine 11 is provided with an R groove 14 at the entrance portion of the conveyance path 13 of the chute 12, and an arrangement conveyance portion 15 is provided on the downstream side.

Further, as shown in Figs. 2(a) to (c) and Fig. 3(a), the transport path 13 of the chute 12 of the straight feed machine 11 is from the exit of the R slot 14 to the entrance of the array transport unit 15. The portion is a shape converting portion 16 in which the cross-sectional shape is smoothly changed from the shape of the R groove 14 in the component conveying direction to the shape of the inlet of the conveying portion.

The configuration of the R groove 14 and the array conveying unit 15 is the same as that of the above. In other words, the array conveyance unit 15 is formed in an L shape in which the conveyance road surface 15a is inclined upward by 15 to 20°, and has a narrow portion in which only the P component that is conveyed in the corner portion of the L-shaped cross section in a good posture is passed, and the posture is poor ( The part P in the longitudinal direction toward the transport path width direction and the longitudinal direction upward is dropped to the recovery unit 17 and is removed from the transport path 13 . On the other hand, the R groove 14 is formed such that the bottom portion (the center portion in the width direction) is slightly higher than the conveying road surface 15a of the array conveying portion 15.

The shape converting portion 16 is inclined downward from the outlet of the R groove 14 toward the inlet of the array conveying portion 15, and the inclination angle thereof is set to 2 to 5 degrees. Further, the length of the shape converting portion 16 is set to be five times or more the length dimension of the component P (in FIGS. 2(a) to (c) and FIGS. 3(a) to (d), the description is more practical. Shorter). Further, the joint between the shape converting portion 16 and the R groove 14 is chamfered. As a chamfering method, for example, polishing film grinding or beading can be used. Processing method, etc.

Further, when the chute 12 is actually produced, the portion of the R groove 14 and the shape converting portion 16 and the portion of the array conveying portion 15 can be formed integrally with each other and then integrated. In this case, the upstream side member is preferably machined along the entire length of the transport direction by the R groove 14 and then processed by cutting the R groove 14 from the downstream side end using the same cutting tool as the downstream side machining part to form a shape conversion portion. 16. Needless to say, the shape conversion portion 16 may be formed by cutting from the upstream side of the upstream side member. Further, it is not always necessary to divide the chute 12 as described above, and one member may be processed to form the R groove, the shape converting portion 16, and the array conveying portion 15, respectively.

Next, the flow of the component P in the vibrating component conveying device will be described. When the component P that has been placed at the bottom of the bowl 2 of the bowl feeder 1 is transported, the transfer path 3 is transferred from the outlet to the entrance of the transport path 13 provided in the chute 12 of the straight feed machine 11. Part of the R slot 14. The parts P transferred to the R grooves 14 of the chute 12 can be temporarily moved in a good posture one by one by the action of the semicircular cross-sectional shape of the R grooves 14 even if they are temporarily changed in posture or overlapped each other during the transfer. The shape conversion unit 16 passes through the shape conversion unit 16 and is sent to the array conveyance unit 15.

At this time, as shown in FIGS. 3( a ) to 3 ( d ), a plurality of parts P enter the shape conversion unit 16 from the bottom of the R groove 14 , and are smoothly moved to the side wall 15 b of the arrangement conveyance unit 15 in a good posture, and are smoothly transferred to The conveying unit 15 is arranged. Further, since the cross-sectional shape of the shape conversion portion 16 is smoothly changed from the R groove 14 to the arrangement conveying portion 15, the parts which enter the shape conversion portion 16 from the lower slope of the bottom portion of the R groove 14 are not shown. P can also be smoothly transferred to the array transport unit 15 without changing the posture.

Then, the part P which has been transferred to the arranging and conveying unit 15 in a good posture is conveyed to the downstream side through the narrow portion along the corner portion of the L-shaped cross section of the arranging and conveying unit 15, and is supplied from the outlet of the conveying path 13 of the chute 12 to The next step. In addition, when the transfer to the arranging conveyance unit 15 is small, the part P which is in a posture failure is small, but the component P having the poor posture is dropped to the recovery unit 17, and then returned to the bowl 2 of the bowl feeder 1.

As described above, the vibrating component conveying device is attached to the R groove 14 provided at the inlet portion of the conveying path 13 of the chute 12 of the straight feeding machine 11, so that the part P received from the bowl feeder 1 is in a row. The one layer is arranged in a good posture, and the components in which the R grooves 14 are aligned are held in a good posture via the shape transfer portion 16 and sent to the array conveying portion 15, so that the outlet of the R groove is directly connected to the inlet of the array conveying portion. In contrast, the number of parts P excluded by the array conveyance unit 15 is small, and the component supply capability can be improved.

Further, chamfering is performed on the joint between the R groove 14 and the shape converting portion 16 of the conveying path 13 of the chute 12, and the shape converting portion 16 is inclined downward at an inclination angle of 2 to 5 degrees toward the downstream side, and Since the length is set to be five times or more the length dimension of the part P, even when the conveyance speed is high, the component P can be smoothly transferred from the R groove 14 to the shape conversion portion 16 and passed through the shape conversion portion 16, Therefore, it is not easy to cause malfunctions such as blockage of parts.

Furthermore, the present invention is not limited to the case where the straight feeder is connected to the downstream side of the bowl feeder as in the embodiment, and can be widely applied to the following vibrating component conveying apparatus: the component is conveyed along a linear conveying path.
