[Industrial applications]

 The present invention is a device relating to a constant quantity feeder for assembling parts, which uses a gas jet pressure and is used in the field of assembling automobiles and various other products.

[0002]

[Prior art]

 Conventionally, relatively light washers made of light metal, synthetic resin, or rubber, which are used for assembling various products, have been picked out from the container in which a large number of containers are stored by picking them one by one during assembly work. However, the washers are flat and lightweight, and they are in an overlapping state.Because the worker wears gloves, it is more difficult to pick up the parts. It had to be put into the container in excess, and when the number was insufficient, it was necessary to take the duplicate work of retrieving the required number from the container again. For this reason, the work efficiency was poor, and when the parts were particularly small, or when they were lightweight, the adverse effects were remarkable.

In order to solve this problem, conventionally, a spiral guideway having an inner width corresponding to the diameter of a small component for assembly and a gentle upward gradient from the bottom of the container is provided on the inner peripheral edge of a circular dish-shaped container. There is a structure in which a sorting tongue that narrows the width of the taxiway is provided in the middle of the taxiway and that projects into the path. Then, by applying a slight vertical movement to this container and slowly rotating it in the same direction as the exit direction of the taxiway, for example, the nuts in the container are guided and lifted into the taxiway while aligning flat and proceeding upright. The selected tongue pieces were dropped onto the bottom of the container while the guide was in progress, and flatly arranged pieces were sequentially provided from the outlet to the assembly process.

[Problems to be solved by the device]

 Since the above-mentioned conventional equipment needs to perform both vibration and rotation simultaneously, there is a problem that the internal mechanism is complicated and expensive while requiring high accuracy.

An object of the present invention is to simplify the structure, to facilitate the operation and to reduce the price, to eliminate the conventional drawbacks, and to make it possible to quantitatively supply small parts for lightweight assembly. It is a device.

[0006]

[Means for Solving the Problems]

 According to the present invention, an assembly place for assembling parts is formed in the container, and a gas ejection hole is provided at this collection place. The container is formed in a shape in which the fumes ejected from the ejection hole recirculate, and the assembly place is formed. The accumulated assembly parts are intermittently ejected from the ejection holes. The air is circulated in the container by the fumes, and the assembly parts are received in the part accommodating portion having a receiving opening that is opened in a direction to receive the recirculating fumes. In order to roll out the container after it has been accommodated in a rollable state through the mouth, a component storage part is provided inside the container, and this component storage part receives the recirculating fumes. A downwardly inclined passage through which the receptacle and the assembly parts can roll upright, an outlet is formed at the outlet side following the downwardly inclined passage, and a through hole communicating with the outlet is formed in the standing wall of the container. And connect it to the outside of the container through the through hole. Attaching a guide portion having a guide groove inclined downward.

【Example】

 FIG. 1 is a perspective view of the present invention, in which an assembling place 2 having a generally funnel-shaped vertical section is formed in a container 1 for assembling a light washer (a) made of, for example, a synthetic resin. A jet hole 3 for jetting gas is formed in the bottom portion 2a of the stacking place 2, and the jet hole 3 is provided to the compressor 5 via an air supply pipe 4 and an air switching valve 5a for intermittently jetting the jet air. It is connected. The container 1 is formed with a semi-circular arc-shaped portion 1a at an upper portion thereof so that the washer (a) scattered by the fumes (b) ejected from the ejection hole 3 is suitable for circulating inside.

In the container 1, a component housing 6 is provided at a position opposite to the fumarole 3, that is, on the side wall 1b on the side where the recirculating fumes (b) are directed downward.

The component housing 6 has a receiving port 7 in the shape of an inverted “C” in the vertical direction, which is opened in a direction in which the recirculating and downwardly blowing fumes (b) are received, and the fumes (b) The width s (at least a little wider than the thickness t of the washer) that allows the washer (a) caught on the receiving port 7 during riding and standing upright by its own weight, and the downward inclined passage 8 that can roll after standing upright. A discharge port 9 is formed on the outlet side continuing from the downward inclined passage 8.

Further, a guide tube serving as a guide portion is provided with a through hole 10 communicating with the discharge port 9 in the front wall 1c of the container 1 and a guide groove 11a formed outside the container 1 and communicating with the through hole 10. Install by tilting 11 downward.

In the figure, reference numeral 12 is a balance stopper provided near the outlet 11b of the guide cylinder 11, and a support shaft 13 provided in the guide cylinder 11 is provided with a metal member composed of an engaging / disengaging rod 14, a stop rod 15 and a weight portion 16. The tool is supported so that it can be reciprocally rotated in the same direction as the method of dropping the assembly part (a).

The operation of the present invention will be described. When a large number of lightweight washers (a) made of, for example, synthetic resin, which are assembly parts, are put into the container 1, they are accumulated in the funnel-shaped collecting place 2. .

Then, when the compressor 5 is operated to inject gas intermittently through the air switching valve 5 a and the air supply pipe 4 from the ejection hole 3 by the operation of the air switching valve 5 a, the fumes (b) are discharged from the container 1 Since it is ejected upward in the lower part of the one side wall 1b, a part of the washer (a) is scattered upward. The fumes rise along one side wall 1b of the container 1, swirl along the semi-circular arc-shaped portion 1a, further descend along the other side wall 1b of the container 1 and the parts accommodating portion 6, and partly descends and slopes. It is discharged from the passage 8 to the outside through the through hole 10, a part of it reaches the funnel-shaped accumulation place 2, and the fumes (b) circulate in the container 1.

A plurality of washers (a) around the ejection hole 3 circulate in the container 1 together with the recirculating fumes (b), and one side of the periphery of the washer (a) is a reverse "ha" of the component housing part 6. When it is caught in the "-shaped" receiving port 7, the width (s) of the downward sloping passage 8 is formed slightly wider than the thickness (t) of the washer (a). The washer (a), which has fallen into the directional inclined passage 8 due to its own weight, stands upright and at the same time rolls in contact with the downward inclined passage 8 in the component housing 6. Then, it reaches the rolling outlet 11b from the discharge port 9 of the component housing portion 6 through the through hole 10 and along the guide groove 11a of the guide cylinder 11 provided outside.

The fumes (b) are not constantly ejected from the ejection holes 3 and are ejected intermittently by the operation of the air switching valve 5 a, so they are accommodated in the component accommodating portion 6 at the moment when the ejection is stopped. The washer (a) that has fallen to the collection place 2 accumulates on the ejection hole 3 and is scattered upward again by the injection of the next fumarole (b).

[Effect of device]

 Therefore, according to the present invention, the assembly parts accumulated in the container can be housed one by one in the parts housing part and sent out to the outside of the container. Therefore, the parts made of synthetic resin, rubber or light metal can be used. The conventional inconvenience and inefficiency in the work process that occur when picking out relatively small parts for assembly from the container are eliminated. In addition, a semi-circular arc is formed on the top of the container so that the fumes and parts for assembly are shaped so as to easily recirculate in the container, and the component housing is provided on the side where the fumes and parts descend. Since the receiving port formed in the component storage part is formed in an inverted "C" shape, there is a high probability that the circulating components will be stored. Since it is formed slightly wider than the thickness of the component, the component is kept upright and can roll, and the downward sloping passage is formed inside the component housing, so the component rolls by its own weight and Due to the rotational force, the guide groove of the guide portion that is inclined downward through the through hole can be rolled and reliably taken out to the outside.

Further, since the fumes are ejected intermittently, the accumulation of the assembly parts around the ejection holes, the accompanying scattering, and the effect of recirculation are smoothly performed.
