Abstract

PURPOSE:To supply cylindrical cap-shape parts one by one successively to a part working machine without damage due to mutual collision between the parts. CONSTITUTION:In a part housing box 10 whose front face is opened to form a part inlet/outlet port 12 and in whose rear face a part push-out window 14 is provided, parts 18 are arranged lengthwise and breadthwise for housing on an inside shelf board 16. While the part housing box 10 is placed on an elevating arm 34 and elevated, a part push-out plate 38 is advanced through the part push-out window 14 in the rear face of the part housing box 10 placed on the elevating arm 34 so as to push out the parts 18 arranged on the shelf board 16 onto a part conveyor 42. Accordingly, parts can be supplied one by one successively to a part working machine without requiring an excessive device such as a tray draw-out device and a tray draw-out base and without damage to the parts due to mutual collision between the parts.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device used when a large number of small components having the same shape are handled.

[0002]

2. Description of the Related Art When a small part, for example, a cylindrical cap-shaped part 18 as shown in FIG. 5 is machined by a large amount of holes, the front and back of the parts are aligned to the processing machine one by one. Although it is necessary to supply the components, a component supply device of this type that has been conventionally used is as shown in FIG. In FIG. 6, a spiral component passage 74 that rises while expanding outward is provided in the outer peripheral cylindrical portion 72 of the cylindrical component pool 70, and a vibration that conveys the component to the outer periphery is applied by a vibration device (not shown). As a result, the parts that have been put into the parts pool 70 climb up in the parts passage 74 in a line. In addition, the parts passage 74
A notch 76 in the shape of a continuous semicircle is provided on the valley side near the upper end of the so as to reverse the front and back of the passing parts and to drop them back from the parts passage 74 to the parts pool 70. It has become.

[0003]

However, in the above-mentioned conventional parts supply device, when parts are supplied to the parts pool, the parts are thrown together into the parts pool, and the parts are notched in the part passage. When the parts are turned upside down, they are dropped into the parts pool, so they collide with each other,
There is a problem that the surface of the part is scratched.

In order to solve the above-mentioned problems of the above-mentioned conventional component supply apparatus, the inventors of the present invention have proposed Japanese Patent Application No. 2-213556.
In No. 5, a large number of trays in which components are aligned vertically and horizontally are housed in a tray box, and the tray box elevating device and the tray pulling device sequentially pull out the trays from the tray box to transport the components aligned on the trays. Has proposed a component supply device that transfers components to a component transfer device and supplies components.

However, the above-mentioned proposed component supply device requires a tray pull-out device and a tray support for supporting the pulled-out tray, resulting in poor work efficiency and an extra space. There is a problem.

The present invention has been made to solve the above-mentioned problems when supplying small parts to a processing machine. It is not necessary to pull out the tray from the tray box and a tray support base is required. First, it is an object of the present invention to provide a component supply device that can immediately supply components from a component storage box in which the components are aligned and stored.

[0007]

In the component supply apparatus of the present invention, a plurality of shelves for accommodating components arranged vertically and horizontally are provided inside, and the front face is opened to serve as a component inlet / outlet and the components are pushed out to the rear face. A component storage box provided with a component push-out window, a lifting arm for mounting and lifting the component storage box, and a component transfer conveyor fixed to the front surface of the component storage box mounted on the lifting arm. And a component extruding device that pushes out the components that enter from the component extruding window on the back surface of the component storage box placed on the elevating arm and that are aligned on the shelf board onto the component conveying conveyor. Use as a summary.

[0008]

The components are vertically and horizontally aligned and stored on the shelf board inside the component storage box. This component storage box is placed on the lifting arm. A component transfer conveyor is fixed to the front surface of the component storage box placed on the elevating arm, and by elevating the elevating arm, the individual shelf boards containing the components are sequentially laid side by side on the component transfer conveyor. It

The component push-out device is provided on the back surface of the component storage box placed on the elevating arm, and the components that enter from the component push-out window on the back surface of the component storage box and are aligned on the shelf board are sequentially transported by the component conveyor. Push it out. By alternately operating the elevating arm and the component extrusion device, the components in the component storage box are sequentially transferred onto the component transfer conveyor and supplied to the processing device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an embodiment of the present invention,
2 is a sectional view taken along line 2-2 of FIG. 1, FIG. 3 is a front view of the component storage box, and FIG. 4 is a rear view of the component storage box.

The component storage box 10 is a box body whose front surface is opened to serve as a component entrance / exit 12, and a component extrusion window 14 is opened on the back surface, and a shelf plate 16 is stacked inside. The shelf board 16 has a bottom plate 22 in which partition members 20 ... Are provided in parallel with the width of the component 18 at equal intervals, and two spacing plates 24 standing upright on two sides of the bottom plate 22 parallel to the partition members 20.
