With such a part supply device, a wide variety of workpieces can be supplied, and among the workpieces, some have protective surfaces that do not want to adhere to dirt. The reason why the protective surface should be protected is different depending on the workpiece. Reasons that may be conceived include, for example, foreign matter such as dirt or the like due to a specific surface of a workpiece, a part of the material, shape, or surface property, and the adhesion of the dirt may hinder performance in terms of effective performance of the performance required for the surface to be protected. Play, or its strength is low and easy to damage. Further, when the surface in which the workpiece is in contact with the most stable state is the bottom surface, the surface to be protected of the workpiece is generally set on the back side of the bottom surface, that is, the plane side.

Even if it is such a workpiece having a protective surface, it is of course the same as other workpieces. According to the shape of the workpiece and the supply destination of the downstream side, the direction of the workpiece must be correctly oriented in the same direction, or it can be recognized as The same direction. Further, in order to effectively protect the to-be-protected surface, the abnormal posture in which the protective surface is in contact with the component supply device side must be eliminated accurately and promptly.

An object of the present invention is to effectively solve the above problems. Specifically, an object of the present invention is to provide a component supply device capable of stably aligning workpieces to improve supply efficiency and to effectively reduce the quality of workpieces during transportation.

The present invention has been made in view of the above problems.

That is, the component supply device of the present invention is characterized in that The first traveling path, the second traveling path, and the third traveling path are provided, and the first traveling path is carried by the workpiece in a rough circular unprocessed area, and the workpiece is placed a portion of the first bottom wall having a width gradually decreasing; the second traveling path having a second side wall and a second bottom wall, the second side wall being a workpiece falling from the first traveling path When the bottom surface is in a normal posture to be transported to the destination, the second bottom wall, when the workpiece having the bottom surface in an abnormal posture that does not contact any of the surfaces falls from the first traveling path, The posture of the workpiece is changed to contact the bottom surface, whereby the workpiece in the normal posture is transported to the supply destination; the third travel path is the workpiece in which the bottom surface and the second bottom wall are in contact with each other The second travel path is guided to the aforementioned unprocessed area.

Here, the "bottom surface" refers to a surface in which the workpiece can be brought into contact in the most stable state during conveyance in the component supply device, in other words, a plane having the largest area among the surfaces of the workpiece. Further, the "bottom surface" is not necessarily narrowly defined to face downward, and certainly does not mean the direction in which the workpiece itself conveyed by the component supply device is assembled and disposed.

According to the above configuration, the posture is appropriately changed when the workpiece reaches the second traveling path, whereby the bottom surface can be brought into contact with either the second side wall or the second bottom wall. In this way, it is not necessary to remove a workpiece in an abnormal posture by air or the like as in the prior art, and a large motion is applied to the workpiece, and only by letting it fall, the workpiece can reach the second bottom wall. The proportion of workpieces in normal posture is greatly reduced. As a result, a component supply device can be provided which can stably arrange the workpieces in order to improve the supply. Efficiency, and can effectively avoid the quality of the workpiece in transit.

Further, in order to allow the workpiece to reach the transport destination more quickly, it is preferable to arrange the first traveling path to be wound around the outer edge of the unprocessed area.

Here, in order to effectively protect the protective surface located on the side opposite to the bottom surface of the workpiece, it is necessary to carry it in such a manner as to minimize the chance of the protective surface being in contact with the component supply device. In other words, in order to lengthen the time when the bottom surface of the workpiece comes into contact with the component supply device side during transportation, when there is a hopper for putting the workpiece into the unprocessed region, the workpiece that is transported in the abnormal posture in the first traveling path is allowed. The position of the posture change is preferably set at a position within 360° of the workpiece thrown from the hopper.

Further, in order to make the workpiece from the first traveling path to the second traveling path to a normal posture at a higher ratio, it is preferable that the second bottom wall is formed to be separated from the first bottom wall by a drop, which is When the workpiece having the bottom surface in contact with the first bottom wall is dropped, the posture can be changed to a normal posture; and the first traveling path has a posture maintaining portion that maintains the posture of the workpiece in the normal posture. Let the workpiece fall to the second walking path.

In particular, in order to more reliably change the posture of the workpiece in an abnormal posture to a posture other than the abnormal posture, the size of the drop formed between the first bottom wall and the second bottom wall is preferably larger than the bottom surface of the workpiece. The overall size is larger.

In the component supply device of the present invention, the workpiece has a bulging surface formed by bulging the shape on the opposite side of the bottom surface, and is substantially positive for the bottom surface. Squares can be more effective. More specifically, when the bulging surface is a lens for constituting an optomechanical part that is partially spherical, the above effect can be more effectively exerted on the workpiece.

According to the invention as described above, it is possible to provide a component supply device which can stably arrange the workpieces in order to improve the supply efficiency, and can effectively prevent the deterioration of the quality of the workpiece during transportation.

As described above, the first bottom wall 31a is configured to support the workpiece W at a position higher than the size of the substrate W1 of the workpiece W by the second traveling path 32 at a portion parallel to the second traveling path 32. The first bottom wall 31a is set such that the width dimension of the supportable workpiece W is gradually reduced, and the first bottom wall 31a disappears, or the portion where the workpiece W cannot be supported regardless of the posture is terminated. In the present embodiment, the end of the first traveling path 31 is set at a position where the workpiece W that has been placed into the unprocessed surface 20 from the hopper H is rotated within 360°. In the present embodiment, the posture changing unit 34 that allows the workpiece W to fall while changing the posture of the workpiece W is provided in the vicinity of the position where the first traveling path 31 starts and the second traveling path 32 is arranged side by side. Further, at the end of the first traveling path 31 or in the vicinity thereof, a workpiece W is maintained while maintaining the normal posture (N). In the posture, the posture maintaining portion 35 for dropping the workpiece W toward the second traveling path 32 is performed. The posture changing unit 34 and the posture maintaining unit 35 will be described later.

The second traveling path 32 has a second side wall 32b and a second bottom wall 32a as shown in Figs. 4 and 5 . The second side wall 32b is in contact with the bottom surface W3 of the workpiece W that has fallen from the first traveling path 31 when it is in the normal posture (N) to be transported to the supply destination R. The second bottom wall 32a changes the posture of the workpiece and brings the bottom surface W3 into contact when the workpiece W in the abnormal posture (X) where the bottom surface W3 is not in contact with either surface falls from the first traveling path 31. The second bottom wall 32a is formed to be spaced apart from the first bottom wall 31a by a gap 36, and the drop W is used to change the posture of the workpiece to a normal posture when the workpiece W in the posture in which the bottom surface W3 is in contact with the first bottom wall 31a is dropped. (N), the size of the drop 36 is set to be larger than the outer shape of the bottom surface W3 of the workpiece W, so that the posture change of the workpiece W can be smoothly performed.

The third traveling path 33 has a guiding surface 33a. The guide surface 33a is for guiding the workpiece W that is in contact with the bottom surface W3 but not in the normal posture (N) when the bottom surface W3 is in contact with the second bottom wall 32a, and is guided from the second traveling path 32 to the storage portion 2. In the present embodiment, as shown in Figs. 1 and 3, the plane view position at which the third traveling path 33 is provided is indicated by a hatching.

Further, in the present embodiment, as shown in FIG. 4, in the vicinity of the position where the first traveling path 31 and the second traveling path 32 are started to be arranged, the workpiece W from the normal posture (N) is set from the first traveling path. The posture changing unit 34 that changes the posture of the workpiece W to the second traveling path 32. Because the terminal of the first traveling path 31 is set in the workpiece W from the hopper H The position is rotated at a position within 360°, and the posture changing portion 34 is of course located at a position within 360° of the workpiece W. Specifically, it is located at a position where the workpiece W is wound from 220 to 230° from the position where the workpiece W is loaded from the hopper H. Hereinafter, the enlarged description of the IV portion of FIG. 4(a), that is, FIG. 4(b), FIG. 4(c) and FIG. 4(d) will be described. FIG. 4(a) shows the workpiece W passing posture changing portion 34. A cross-sectional view of the behavior of the workpiece W at that time. Here, the posture changing unit 34 of the present embodiment refers not only to the positions specifically illustrated in FIGS. 3 and 4 but to all the areas where the workpiece W in the posture other than the normal posture (N) may fall.

Fig. 4(b) shows the behavior of the workpiece W which is not in the normal posture (N) and which is in contact with the first bottom wall 31a. The workpiece W that is in contact with the first bottom wall 31a in the bottom surface W3 is dropped toward the second traveling path 32 so as to be in contact with the second side wall 32b. At this time, most of the workpiece W located on the first traveling path 31 in the state shown in FIG. 4(b) changes its posture to the normal posture (N) when it falls to the second traveling path 32. This is because the size of the drop 36 is ensured to be at least one-half of the outer dimension of the workpiece W, and the angle between the first bottom wall 31a and the second side wall 32b is an obtuse angle and the cross section is continuous.

4(c) shows the behavior of the workpiece W in the abnormal posture (X) in which the bottom surface W3 is not in contact with any of the surfaces and the protective surface W6 having the lens W9 is in contact with the first side wall 31b. The workpiece W that is in the abnormal posture (X) in which the protective surface W6 is in contact with the first side wall 31b is thus dropped toward the second traveling path 32 so as to be rolled off from the first traveling path 31. Most of the workpiece W in the abnormal posture (X) is the bottom surface as shown in Fig. 4(c). The state in which W3 is in contact with the second bottom wall 32a. This is because the size of the second side wall 32b, that is, the size of the drop 36 formed between the first side wall 31b and the second side wall 32b is set to be larger than the size of one side of the workpiece W in a plan view square shape, that is, the outer size. A certain size of a certain size.

Fig. 4 (d) shows the workpiece W conveyed in a normal posture (N) in which the bottom surface W3 is in contact with the first side wall 31b. The workpiece W in the normal posture (N) is conveyed to the posture maintaining unit 35 without being changed in posture by the posture changing unit 34.

Further, as shown in FIG. 3 and in particular, as shown in FIG. 5, the posture maintaining unit 35 is provided at a position where the angle change phase is 30° to 40° from the posture changing unit 34. The posture maintaining portion 35 is located not only at the position specifically illustrated in FIGS. 3 and 5, but also in the normal posture (N) by making the first bottom wall 31a the same or smaller than the thickness of the substrate W1 of the workpiece W. The entire area where the workpiece W may fall.

As shown in FIG. 5, at the end of the first traveling path 31 or in the vicinity thereof, the size of the first bottom wall 31a is reduced to an angle ratio formed by the first side wall 31b regardless of the position W of the workpiece W. The situation of Figure 4 is more inclined and formed upward. Thereby, as shown in FIG. 5(b) of the enlarged view of the V portion, most of the workpiece W is held in the normal posture (N), and as shown in FIG. 5(c), the bottom surface W3 can be in contact with the second side wall 32b. The way to slide down is to fall.

Further, as shown in FIG. 6, the workpiece W shown in FIG. 4(c) is guided from the second traveling path 32 to the third traveling path 33, and the guiding surface 33a on the third traveling path 33 is guided. Return to the unprocessed surface again 20. As shown in FIG. 6, at the installation position of the third traveling path 33, the size of the second bottom wall 32a is also a size that cannot be supported except for the workpiece W in the normal posture (N). As described above, the workpiece W in the state shown in FIG. 4(c) is returned to the unfinished surface 20, but can be re-wound while maintaining the state in which the bottom surface W3 is in contact with each other, and the posture is changed to the posture shown in FIG. 4(b). The normal posture (N) is transported to the supply destination R by the second traveling path 32.

By the workpiece W of the first traveling path 31 and the third traveling path 33, the second traveling path 32 passes through the posture changing device 5 and the eliminating unit E, and only the workpiece W that is in the posture of the predetermined correct direction is supplied to the workpiece W. Destination R supply.

The component supply device of the present embodiment described above is configured to include the first traveling path 31, the second traveling path 32, and the third traveling path 33. The first traveling path 33 has a first bottom wall 31a whose width dimension is gradually narrowed; the second traveling path 32 has a second side wall 32b and a second bottom wall 32a, and the second side wall 32b is from the first traveling path 31. When the bottom surface W3 of the fallen workpiece W is in contact with the normal posture (N) to be transported to the destination R, the second bottom wall 32a, when the workpiece W in the abnormal posture (X) falls from the first traveling path 31 At this time, the posture of the workpiece is changed to bring the bottom surface W3 into contact, whereby the workpiece W in the normal posture (N) is transported to the supply destination R; the third traveling path 33 is in contact with the bottom surface W3 and the second bottom wall 32a. The workpiece W is guided from the second traveling path 32 to the storage portion 2.

According to the above configuration, when the workpiece W reaches the second traveling path 32, the posture is appropriately changed, and the bottom surface W3 can be brought into contact with either the second side wall 32b or the second bottom wall 32a. Result, when the workpiece When W reaches the second bottom wall 32a, the proportion of the workpiece W in the abnormal posture (X) can be greatly reduced. In particular, in the conventional case, it is necessary to remove the workpiece W in the abnormal posture (X) from the conveyance path 3 by air or the like, and apply a large operation or impact to the workpiece W. However, in the present embodiment, the operation and the collision can be avoided. The posture change of the workpiece W can be realized only by a small movement of dropping the workpiece W to the parallel traveling path. In this way, although the conveyance path 3 is set to be short, a component supply device can be realized which can stably arrange the workpieces W in order to improve the supply efficiency, and can effectively prevent the quality of the workpiece W during transportation from being lowered.

Further, in the present embodiment, the first traveling path 31 is set to be wound around the outer edge of the unprocessed region, that is, the outer edge of the storage portion 2. Therefore, the structure of the existing conveying path 3 can be changed without requiring a large specification change. The workpiece W is quickly brought to the supply destination R.

In particular, in the present embodiment, the posture changing portion 34 is provided at a position within 360° of the workpiece W inserted from the hopper H, so that the posture of the workpiece W in the abnormal posture (X) in contact with the protective surface W6 can be quickly established. The change helps to protect the face W6 from further protection.

Further, in the present embodiment, the second bottom wall 32a is formed to be spaced apart from the first bottom wall 31a by a drop 36 which can be changed to a posture when the workpiece W in the posture in which the bottom surface W3 is in contact with the first bottom wall 31a is dropped. In the normal posture (N), the posture maintaining unit 35 is provided, and the posture maintaining unit 35 can maintain the posture of the workpiece W in the normal posture (N) and the workpiece W from the first traveling path 31 to the second traveling path 32. The workpiece W from the first traveling path 31 to the second traveling path 32 can be surely made a normal posture at a higher ratio. Potential (N).

In particular, in the present embodiment, by setting the size of the drop 36 formed between the first bottom wall 31a and the second bottom wall 32a to be larger than the outer shape of the bottom surface W3 of the workpiece W, it is possible to be in an abnormal posture (X). The workpiece W is more surely dropped by the posture in which the posture is changed to a posture other than the abnormal posture (X).

Further, in the component supply device of the present invention, the workpiece W has a bulging surface formed by bulging the shape, that is, a protective surface W6, and a substantially square surface of the bottom surface W3, and the workpiece W is dropped by the workpiece W. When the posture is changed, the protection of the protective surface W6 can be facilitated by a simple structure, and the effect can be more effectively exerted. According to this embodiment, the lens W9 located on the protective surface W6 can be effectively protected, and the workpiece W can be stably conveyed.

The above is an embodiment of the present invention, but the present invention is not limited to the structure of the above embodiment. For example, in the above-described embodiment, the storage portion is set in an unprocessed region where no posture change is performed on the workpiece, and the first traveling path, the second traveling path, and the third traveling path are formed on the conveyance path from the storage portion to the supply destination. However, it is a matter of course that a part of the storage portion constitutes the first traveling path, the second traveling path, and the third traveling path. In other words, it is also possible to make the bottom surfaces of all the workpieces in contact before the conveyance path. However, in order to apply this aspect, it is necessary to adopt a special structure in the storage portion so that all the workpieces reach the first traveling path.

Various modifications can be made without departing from the spirit and scope of the invention.
