Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device that suspends and horizontally conveys a headed component.

As shown in Patent Document 1, a conventional component supply device includes a basket capable of storing a large number of headed components, a scoop plate capable of scooping up the headed components from the basket, supporting them in a suspended manner, and swinging. a chute rail extending in front of the oscillating path of the scoop plate so that the headed part can be suspended and supported in a vertical posture and opposed to each other at a predetermined interval; and a vibrating body capable of imparting vibration to the chute rail; An escapement is arranged to contact the front end of the chute rail and is capable of receiving the headed parts one by one and sequentially discharging them to the next process.

The scoop plate is provided with a support groove capable of guiding the shaft portion of the headed component so as to be able to pass therethrough and supporting the head of the headed component by suspending it. Further, the shoot rail guides the shaft portion at a constant interval from the rear end to the front end, while allowing the head portion to be suspended. In addition, the chute rails are arranged in parallel and set at regular intervals, and are configured to suspend the heads of the headed components and guide the shafts of the headed components at the intervals.

The operation of the conventional component supply device configured in this way will be described. The scoop plate swings to scoop upward the headed components in various postures stored in the basket. This causes the headed part to be lured into the support groove or to slide back into the basket. Here, the headed part guided by the support groove of the scoop plate slides down toward the rear end of the chute rail due to further swinging of the scoop plate, and changes from an oblique posture to a vertical posture. Also, the headed parts suspended in this vertical posture are oscillatingly transported in a line toward the escapement. Further, the escapement receives the headed parts ejected from the rear end of the chute rail one by one and sends them one after another to the next process such as a screw tightening machine.

Patent No. 4464094

However, in the conventional component feeding device disclosed in Patent Document 1, when the interval between the chute rails is set to a dimension that is substantially the same as the diameter of the shaft portion of the headed component, the inlet of the headed component received from the scoop plate is narrow. , there is a problem that it is difficult to secure the supply amount of headed parts. Conversely, in the conventional parts feeder, when the distance between the chute rails is set to be sufficiently larger than the shaft diameter of the headed part, the position of the headed part delivered to the escapement is There is also a problem that it tends to fluctuate in the orthogonal direction. In this way, the conventional parts supply device tends to cause problems when receiving parts with heads from the scoop plate to the chute rail and when transferring them from the chute rail to the escapement, and ensures a stable supply of parts with heads. I had a difficult problem.

The present invention comprises a basket capable of storing a plurality of headed components, a scoop plate capable of scooping up and swinging the headed components in the basket, and a scoop plate extending forward of the swing path of the scoop plate. a shoot rail capable of receiving and suspending a scooped-up headed component; a vibrating means for fixing the shoot rail and imparting vibration to the shoot rail; and an escapement that receives the headed component discharged from the front end side and supplies it to the next process, wherein the shoot rail is spaced at a predetermined interval so that the shaft portion of the headed component can be inserted. a first rail and a second rail arranged opposite to each other, and the interval between the first rail and the second rail is set so as to gradually decrease from the side of the scoop plate toward the side of the escapement. Characterized by The vibrating means includes a vibrating body for generating vibration, a mounting screw capable of fixing the shoot rail to the vibrating body, and a spacer having a different thickness interposed between the vibrating body and the shoot rail. It is desirable that both the first rail and the second rail have the same thickness.

Since the component feeding device according to the present invention is configured such that the interval between the first rail and the second rail gradually decreases toward the escapement side, the scoop plate side with the wide interval can easily receive the headed component, and The side of the narrowly spaced escapement has the advantage of facilitating positioning and delivery of the headed component to the escapement. As a result, the parts supply device according to the present invention can efficiently transfer the headed parts from the scoop plate to the chute rail, and stably supply the headed parts that are less likely to be caught in the escapement. can carry out transportation. In addition, since the component supply device of the present invention is provided with spacers with different thicknesses that can adjust the interval between the first rail and the second rail with the same thickness, it is possible to form slopes on the first rail and the second rail. There is also the advantage that it does not require any special processing, making it possible to reduce costs.

1 is a schematic diagram of a component supply device according to the present invention; FIG. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of a component supply device according to the present invention, and FIG. 1A is an explanatory view of a main part showing a first rail and a second rail having the same plate thickness and gradually reducing the distance between shoot rails by spacers; (b) is an explanatory view of a main part showing a configuration in which the facing surfaces of the first rail and the second rail are inclined without using spacers to gradually reduce the interval.

A component supply device according to the present invention will be described with reference to FIGS. 1 and 2. FIG. A parts supply apparatus 1 according to the present invention comprises a basket 6 capable of storing a plurality of screws S, which are examples of headed parts, and a scooping plate 7 arranged swingably in the basket 6 and capable of scooping up the screws S. , a chute rail 10 arranged to extend in front of the oscillating path of the scoop plate 7 , a vibrating means 20 for fixing the chute rail 10 and imparting vibration to the chute rail 10 , and the chute rail 10 . and an escapement 30 arranged to contact the front end.

The basket 6 is formed in the shape of a mortar, and is capable of storing a large number of the screws S in advance. The basket 6 is formed so that the rear end of the chute rail 10 can be arranged therein, and the bottom thereof is formed so that the scoop plate 7 can be arranged swingably.

The scoop plate 7 has a substantially sector shape and is configured to be swingable in the basket 6 along the rear end of the chute rail 10. The scoop plate 7 guides the shaft portion S2 of the screw S and It comprises a suspension groove 7a capable of suspending and supporting the portion S1. The suspension groove 7a has a groove through which the shaft portion S2 of the screw S stored in the basket 6 can be inserted, and is configured such that the head S1 of the screw S inserted through the groove can be suspended from the upper surface of the groove. It is The scoop plate 7 has the suspension groove 7a substantially horizontal at the bottom of the basket 6, which is the swing bottom dead center, while the suspension groove 7a is tilted at the top of the basket 6, which is the swing top dead center. Become. Therefore, the scoop plate 7 can scoop up the screws S stored in the basket 6 by swinging, and the screws S suspended in the hanging grooves 7a can be slid down from the hanging grooves 7a to the chute rail 10 and supplied.

The vibrating means 20 includes a vibrating body 21 that can oscillate in the front-rear direction, and the shoot rail 10 can be fixed to the vibrating body 21 . The shoot rail 10 can be fixed to the vibrating body 21 by hexagon bolts, which are an example of mounting screws. As shown in FIGS. are using. As a result, the vibrating means 20 can slightly vibrate the chute rail 10 integrated therewith in the front-rear direction, so that the screw S suspended from the chute rail 10 is moved from the rear end side of the chute rail 10. It will move toward the front end side.

The chute rail 10 comprises a first rail 11 and a second rail 12 which are arranged opposite to each other with a predetermined gap between them. The dimensions are set so that the portion S1 can be suspended and supported. The distance between the first rail 11 and the second rail 12 is set to be 1.05 to 1.25 times the shaft portion S2 of the screw S, as shown in FIGS. As shown, the dimensions are set to gradually decrease from the side of the scoop plate 7 toward the side of the escapement 30 . Specifically, the space A located on the side of the scoop plate 7 is set to be 1.25 times the size of the shaft S2, and the space B located on the side of the escapement 30 is 1.05 times the size of the shaft S2. The dimensions are set to be doubled, and are arranged so as to satisfy the dimensional relationship of interval A > interval B and to gradually decrease toward the escapement 30 side.

In this way, by setting the interval A located on the rear end side of the chute rail 10 wide, it is easy to guide the shaft portion S2 of the screw S that slides down from the scoop plate 7 to the chute rail 10, and the first rail 11 and the second rail 11 are easily guided. The head S1 can be supported on the upper surface of the rail 12, and the screw S can be stably suspended by always suspending one head S1 with two members. Further, by narrowing the interval B located on the front end side of the chute rail 10, the screws S suspended from the chute rail 10 are less likely to be displaced in the direction perpendicular to the conveying direction. Therefore, the screws S conveyed from the chute rail 10 to the escapement 30 can be gradually aligned linearly with respect to the conveying direction, and the delivery of the screws S to the escapement 30 is stabilized.

The escapement 30 is configured to sequentially receive the screws S discharged from the rear end side of the chute rail 10 and supply them to the next process. and a discharge hole 32 having a hole diameter that allows the head S1 of the screw S to pass through. Also, the escapement 30 is constructed so that the receiving plate 31 can move toward the discharge hole 32, and is normally positioned on the rear end side of the chute rail 10 as shown in FIGS. While connecting, the screw S suspended from the receiving plate 31 is moved from this position toward the discharge hole 32 side and supplied to the next process.

As described above, the first rail 11 and the second rail 12 need only be arranged so that the interval gradually decreases from the side of the scoop plate 7 toward the side of the escapement 30, and each has a uniform thickness. may have been In this case, when fixing to the moving means 20, as shown in FIGS. 1 and 2A, spacers 21a and 21b having different thicknesses are used and fixed with the hexagonal bolt. The spacer 21a is attached to the side of the scoop plate 7 and is thinner than the spacer 21b. On the other hand, the spacer 21b is attached to the side of the escapement 30 and is thicker than the spacer 21a. In this manner, the vibrating means 20 fixes the shoot rail 10 using the spacers 21a and 21b having different thicknesses, so that the first rail 11 and the second rail 12 are uniformly vibrated as shown in FIG. 2(a). It is possible to gradually decrease the interval B from the interval A while setting the thickness T. Therefore, since the first rail 11 and the second rail 12 can each be made of parts having the same thickness T, it is possible to improve the manageability of the parts.

In addition, since the first rail 11 and the second rail 12 gradually reduce the dimension of the interval B from the interval A, as shown in FIG. Thickness may be adopted. That is, while the outer widths C and D of the first rail 11 and the second rail 12 are the same size, the gaps A and B are set to different sizes. The opposing surface of the rail 12 may be processed to be an inclined surface. Therefore, it becomes possible to eliminate the need for dimensional adjustment of the gaps A and B by the spacers 21a and 21b, and the assembling workability can be enhanced.

The component feeding device 1, which has dimensions that gradually decrease from the interval A toward the interval B of the chute rail 10, has a configuration in which the screw S is easily received from the scoop plate 7, so that the outer diameter of the head portion is large and the length of the shaft portion is large. A part with a long head, which is particularly difficult to scoop up by the scoop plate 7, can be reliably guided to the chute rail 10.例文帳に追加Therefore, it is possible to increase the supply amount of headed parts compared to the conventional art.
