Description

  The present invention relates to a component supply apparatus that can take out a necessary number of components from a storage unit in which a plurality of components are stored.

  Conventionally, as a device that can take out a plurality of components in an aligned state from a housing portion that houses a plurality of components, there is a component supply device as disclosed in, for example, Japanese Patent Application Laid-Open No. 05-077918. Such a component supply device applies a combined vibration of swinging and reciprocating motion to a housing box for housing the component by the driving device and an aligning portion for aligning the component, and continuously adjusting the directionality of the component by this vibration. The parts are moved by vibrating almost the whole apparatus.

  However, the supply of parts by the above-described conventional method is provided with a drive mechanism that transmits power from a power source such as a motor over almost the entire route through which the parts are supplied, which increases the size of the apparatus and reduces the manufacturing cost. There was a problem that it became expensive and maintenance was difficult.

  The present invention was devised to solve such problems, and the parts installation area is small, so that the cost, development man-hours and installation man-hours can be reduced and maintenance is not required. An object is to provide an apparatus.

In the first aspect of the invention, the storage unit is configured to be connected to the storage unit that stores the components, the quantity adjustment unit that adjusts the number of components discharged from the storage unit, and the quantity adjustment unit. A slide part having two or more downhills that incline relative to the parts thrown in from the quantity adjusting part, and is provided at the end of downhill of the slide part and connected to the downway, the slide part A receiving portion for receiving the component that has descended from the surface, and a closing wall for closing the component that descends to the downhill end, and a direction perpendicular to the direction in which the component slides down with a fulcrum provided at the end as a center Can be swung up and down approximately 30 degrees, and when swinging, the holding unit further includes a blocking wall that closes the sliding end of the sliding unit, a moving mechanism that swings the holding unit, and the holding mechanism that holds the holding unit. The part swings Characterized in that it comprises a take-out portion for taking out a was Desa had parts.

The invention according to claim 2 is characterized in that the slide portion is inclined downward by 20 to 25 degrees with respect to the horizontal direction in a side view.

According to a third aspect of the present invention, a vertical wall portion is provided on one side in the width direction of each downhill of the slide portion, and the bottom of the downstream portion of the downhill of the slide portion is perpendicular to the downhill direction from the intermediate position. It is characterized by being inclined at a downward angle of 5 to 10 degrees toward the vertical wall.

According to a fourth aspect of the present invention, the closing wall of the holding portion is 1 mm lower than the plate thickness of the component.

In the present invention, since the component accommodated in the accommodating portion slides down by its own weight using the inclination of the slide portion and can be taken out at the downstream outlet, the power source for conveying the component is This eliminates the need for cost, maintenance man-hours, and reduction in the installation area of the apparatus.

In addition, a plurality of parts housed randomly in the housing part slide down continuously along the plurality of downhills, and one part is temporarily held in each downway by a holding part located at the downstream end of the downway. Since the component supply device can be separated from the components that are continuous in the downway, the necessary number of components can be simultaneously extracted.

Further, by setting the inclination of the slide portion downward from 20 degrees to 25 degrees, the gravity and dynamic friction force acting on the parts are balanced, and an appropriate speed can be maintained without stopping.

In addition, a vertical wall portion is provided on one side in the width direction on each downhill of the slide portion, and the bottom portion of the downstream portion is inclined downward from 5 degrees to 10 degrees toward the vertical wall portion from the intermediate position of each downhill road. The parts can be slid down without deviating from the runway and one part can be aligned with the holding part in each runway.

In addition, since the retaining wall of the holding part is set to be 1 mm or more lower than the thickness of the part, excess parts slide down from the top of the part closed by the holding part, and two or more parts are held in one holding part. There is nothing to do.

It is a side view of the component supply apparatus of this invention. It is a principal part detailed perspective view of this invention. It is sectional drawing which shows the shape of the slide part in sectional view perpendicular | vertical to a downhill direction. It is a figure which shows the shape of a holding | maintenance part.

  Hereinafter, an embodiment of a component supply device of the present invention will be described based on the drawings with reference to FIGS. FIG. 1 is a side view showing the configuration of a component supply device 1 according to the present invention. The component supply device 1 is roughly divided into a storage unit 2 for storing components, a quantity adjustment unit 3, a slide unit 4, and a holding unit 5. The take-out unit 6 and the moving mechanism 7 are configured. From the slide part 4 toward the holding part 5, the slide part 4 is inclined downward toward the downhill direction in a side view with respect to the horizontal direction as a whole. For this reason, the component is moved downward by gravity from the component accommodating unit 2 via the quantity adjusting unit 3, reaches the holding unit 5, and is extracted by the extraction unit 6.

(Container)
In FIG. 1, the accommodating portion 2 has an upper surface opened to form a space in which a substantially rectangular component can be accommodated, and the bottom portion is inclined at a predetermined angle. A part of the bottom of the accommodating portion 2 is opened so that the inner surface of the accommodating portion 2 and the quantity adjusting portion 3 can communicate with each other, and a communication passage 2a is provided.

(Quantity Adjustment Department)
Three rotating magnets (not shown) are embedded in a horizontal row in the width direction of the rotating drum, and four magnet groups are provided at four equal intervals in the rotating drum section. In the present embodiment, three parts are taken out, but two parts or four or more parts may be used as necessary. Thereby, the components accommodated in the accommodating portion 2 are magnetically attracted to the magnet through the communication path 2a. The part magnetically attracted to the magnet rotates while being magnetically attracted with the rotation of the rotating drum and is put into the slide unit 4.
A rotating mechanism 9 for rotating the rotating drum is provided at the lower part of the rotating drum stand. When the operator pushes the lever 10 installed at the lower part of the apparatus, the pulley 9a moves in the horizontal direction, and moves up and down the flat rack 9b chopped by a wire fixed at one end to the frame. Thus, rotational force is applied to the pinion 9c. By doing so, the rotating drum is rotated by driving the belt 9d coupled to the rotating drum. Further, the rotation mechanism 9 may be rotated by an operator turning a lever (not shown) provided on the side of the rotary drum.

(Slide part)
The slide portion 4 has a width equivalent to that of the rotating drum, and the width direction is divided into a plurality of as shown in FIG. 2 to form a plurality of downhill paths 4a, 4b, and 4c. The vertical walls 4-1, 4-2, and 4-3 project from the end portions of the downhills, and the downways are formed in an L shape as a whole in a cross-sectional view perpendicular to the downhill direction. It is arranged in a shape. Moreover, the inclination of the slide part 4 takes a downward inclination angle in the down direction of 20 to 25 degrees with respect to the horizontal direction in a side view, and the part slides down the slide part 4 by the action of gravity. The tilt angle may be fixed, or may be a structure that can be changed by the adjuster 8 as shown in FIG. In addition to gravity, parts receive dynamic frictional force from the downhill, but the coefficient of dynamic friction varies depending on factors such as downway, surface properties of the parts, and shape of the parts. The speed of the parts can be adjusted so that the parts do not stop in the middle of the runway and reliably stop at the closing wall.
In FIG. 1, the downways 4a, 4b, and 4c of the slide portion 4 for sliding down the parts are arranged in three rows in the width direction. However, the number of downways may be two rows or four or more rows as necessary. In this embodiment, the bottoms of the downways 4a, 4b, and 4c are set slightly wider than the longitudinal dimension of the component, but are formed to have a dimension that is greater than or equal to the longitudinal dimension of the component and approximately twice or less. It only has to be.

Further, the angle of the bottom portion in the cross-sectional view perpendicular to the downhill direction of the downways 4a, 4b, and 4c is the horizontal direction (cross section AA) and the intermediate position as shown in FIG. On the downstream side, as shown in FIG. 3 (b), it is inclined downward (cross section BB) by 5 degrees to 10 degrees downward toward the vertical wall portion in a sectional view perpendicular to the downhill direction. Each of them is gradually inclined so as to incline in the direction of the vertical wall as it goes downstream. As a result, it is possible to prevent the parts from dropping out to the lower runway.
On the contrary, the heights of the vertical wall portions 4-1, 4-2, 4-3 are set to be substantially equal to the plate thickness of the parts, so that the lower runway to the upper runway The movement of parts can be prevented. In addition, smooth operation can be realized without interference between adjacent downhill components.
The length of the runway is determined mainly from the viewpoint of securing the length necessary for alignment and ensuring the compactness of the device, but at present, the length is about 10 parts on the shortest runway. .

(Holding part)
In FIG. 1, the holding part 5 is located at the end of the downhill of the slide part 4 and is connected to the downway. The holding part 5 has a receiving part 5a for receiving the parts down the downways 4a, 4b, 4c. In order to stop the flow of parts, a closing wall 5b is provided at the downstream end of the receiving portion 5a. As shown in FIG. 2, the receiving portion 5a has the same cross-sectional shape as that of the downhill end in a cross-sectional view perpendicular to the downhill direction, and the length in the downhill direction is set to be approximately 1 mm shorter than the short side of the component. As a result, the subsequent part is formed so as not to be held by the receiving part 5a, so that when the holding part 5 performs a paying-out operation, the next part will not be lifted up by the receiving part and will be moved to the holding part 5 next time. Can be aligned.

The height of the closing wall 5b is set to be about 1 mm lower than the thickness of the component. Since the closing wall 5b has a sufficient height, when the component stops, the component can be reliably closed without generating a moment in the direction in which the component floats. In addition, since the height of the closing wall is lower than the thickness of the part, even if the parts overlap and fall down to the receiving part 5a, they pass through the discharge passage 11 at the downstream end of the holding part 5 without being closed by the closing wall 5b. And collected in the collection box 12. As shown in FIG. 4, the holding part 5 is provided with a fulcrum 5c, and in order to take out the held part to the take-out part 6, the vertical direction about 30 degrees in the direction perpendicular to the direction in which the part slides down with the fulcrum 5c as the center. Can be swung. The holding portion 5 has a substantially plate-like blocking wall 5d for closing the downhill end of the downhill so that parts do not fall from the downhill end of each downhill 4a, 4b, 4c when the holding portion 5 swings. Is provided.

(Movement mechanism)
The moving mechanism 7 is a mechanism for swinging the holding portion 5 in the vertical direction. The moving mechanism 7 is provided with a moving body 7 that reciprocates in the vertical direction. The swinging portion 5e of the holding portion 5 shown in FIG. 7 and can be linked. When the moving body 7 moves upward due to the reciprocating motion of the moving body 7, the swinging portion 5e of the holding portion 5 is interlocked to swing upward about 30 degrees around the fulcrum 5c. Has been made. When the holding part 5 is swung upward by the moving mechanism 7, the downhill end of the downhill paths 4a, 4b and 4c is closed by the closing wall 5d provided at the lower part of the holding part 5 so that the parts do not fall. Has been made.
The mechanism for reciprocating the moving body 7 can reciprocate the moving body 7 by providing a lever 10 in the apparatus and driving the lever by an operator.

(Removal part)
The holding unit 5 is swung upward by the moving mechanism 7, and a plurality of parts are slid to the take-out part 6 and discharged at a time, and a necessary number of parts can be taken out from the take-out part 6.

In the present embodiment, the shape of the component is substantially rectangular, but the shape of the component may be a square, trapezoid, circle, or a polygon more than a quadrangle, and the shape is not particularly limited.
