Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a parts supply device that supplies parts from a parts supply device such as a parts feeder to a parts receiving device such as a nut runner.

[Technical background of the invention and its problems] For example, on an engine assembly line, when tightening a nut on a bolt protruding from the engine body, the nut runner automatically tightens the nut. A nut runner is installed to tighten nuts against the engine body flowing on the line. Therefore, it is necessary to supply nuts to each nut runner each time, and conventionally nuts are supplied to each nut runner from a parts feeder. However, installing one parts feeder for one nut runner requires as many parts feeders as the number of nut runners, which increases costs and requires a large space to install the parts feeders. In addition, for example, if two nut runners are installed together, but depending on the model, only one nut runner is operated, the corresponding parts feeder must be stopped, resulting in poor parts feeder availability. There is.

[Purpose of the invention]

This invention was made with attention to the above-mentioned circumstances, and its purpose is to be able to supply parts from one parts supply device to two receiving devices, and to also be able to supply parts from the receiving device to two receiving devices. It is an object of the present invention to provide a component supply device that can selectively supply the components to the acceptance device in response to an acceptance request signal.

[Summary of the invention]

In order to achieve the above object, the present invention provides first and second escape devices in the supply path of the component supply device, and operates the first and second escape devices in response to a component acceptance request from the acceptance device. The object of the present invention is to allow parts to be received from the supply path and selectively supplied to the receiving device.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows the overall configuration of the parts supply device, and numeral 1 indicates a parts feeder as the parts supply device.

This parts feeder 1 is composed of a main body 3 that accommodates parts 2 and a supply path 4 that supplies the parts 2. The parts 2 are, for example, cap nuts, and are aligned and aligned by vibration from the main body 3. A first escape device 5 and a second escape device f6, which will be described later, are provided at the tip of this supply path 4. Device 6 has a first
A component discharge path 7 and a second component discharge path 8 are provided, and are connected to a first receiving device 9 and a second receiving device 10, respectively.

As shown in FIG. 2, the first escape device 5 is composed of a solenoid 11 and a stopper 12 that is pushed and retracted by the solenoid 11.

The solenoid 11 is attached to the distal end of the supply path 4 by a bracket 13, and the stopper 12 comes into contact with the frontmost component 2 of the supply path 4 when it is projected to stop the supply. In addition, the second escape device 6
is constructed as shown in FIGS. 3 and 4. That is, 14 is a base, a first outlet 15 is provided at one end of the base 14, and a second outlet 16 is provided at the other end in parallel. The component discharge path 7 and the second discharge port 16 communicate with the second component discharge path 8, respectively. Further, a slider 17 is slidably provided on the upper part of the base 14, and is driven by an air cylinder 18.

Further, the slider 17 is provided with a first receiving opening 19 and a second receiving opening 20 each of which is a notch and faces the tip of the supply path 4 . These receiving ports 19.
20 has a space for accommodating one component 2, and faces the first discharge port 15 and the second discharge port 16 by sliding the slider 17. Then, when the first receiving port 19 faces the first discharging port 15, the internal parts 2 are dropped into the first discharging port 15, and when the second receiving port 20 opposes the second discharging port 16. , the internal parts 2 are dropped into the second discharge port 16. In other words, when the slider 17 retreats, the first
The receiving port 19 faces the supply path 4 , and the second receiving port 20 faces the second discharge port 16 . Further, when the slider 17 moves forward, the first receiving eye 19 faces the first outlet 15, and the second receiving eye 19 faces the first outlet 15.
The receiving port 20 faces the supply path 4.

Further, the first and second discharge passages 7.8 connected to the second escape device 6 are formed by tubes, for example, and
The parts 2 are moved by air pressure and supplied to the first and second receiving devices 9.10.

These receiving devices M9.10 are, for example, nut runners, which are supplied to the engine body (not shown) to tighten the cap nuts.

Next, the operation of the parts supply device will be explained. First, when the parts feeder 1 is operated, the parts 2 are aligned and aligned by vibration and are sequentially supplied to the supply path 4. Then, it is supplied from the tip of the supply path 4 to the second escape device W6.

At this time, when a component acceptance request signal is input from the first acceptance device 9 to the second escape device 6, the slider 17 moves back and waits as shown in FIG. 3(A). Therefore, the component 2 from the supply channel 4 enters the first receiving port 19 .

Next, as shown in FIG. 3B, when the slider 17 moves forward, the first receiving port 19 faces the first discharging port 15,
The part 2 falls into the first discharge port 15.

This part 2 is then supplied to a first receiving device 9 via a first discharge path 7. On the other hand, at this time, the second receiving port 20 faces the supply path 4, but since the stopper 12 of the first escape device 5 is protruded by the solenoid 11, the most advanced component 2 is stopped by the stopper 12. There is. Therefore, the part 2 never enters the second receiving hole 20. Next, when the slider 17 moves back again, the first receiving port 19 faces the supply path 4 . Then, when the stopper 12 is retracted by the solenoid 11 of the first escape device 5, the most advanced part 2 enters the first receiving hole 19. Then, when the slider 17 moves forward again, the first receiving port 19 faces the first discharging port 15, and the part 2
falls and is supplied to the first receiving device 9 via the first component discharge path 7. Further, when a parts acceptance request signal is input from the second acceptance device 10 to the second escape device 6,
As shown in FIG. 4(A), the slider 17 moves forward and the second receiving port 20 faces the supply path 4.

The most advanced part 2 thus falls within the second receiving eye 20 . Next, when the slider 17 retreats, the second receiving eye 20 faces the second discharge port 16, and the component 2 falls to the second receiving hole 20.
The parts are supplied to the second receiving device 10 via the parts discharge path 8 . At this time, the first receiving port 19 faces the supply channel 4, but the most advanced component 2 in the supply channel 4 is in contact with the stopper 12 of the first escape device [5], so the first receiving port 19 faces the first receiving port 19. It never enters. When the slider 17 moves forward again, the second receiving opening 20 faces the supply channel 4, and when the stopper 12 is retracted by the solenoid 11, the most advanced part 2 enters the second receiving opening 20. Then, when the slider 17 retreats again, the part 2 in the second receiving hole 20
falls into the second discharge port 16 and is supplied to the second receiving device 110 via the second discharge path 8. In this way, the first
, the first and second escape devices 5.6 are operated in response to a component acceptance request signal from the second acceptance device 9.10 to selectively supply the component 2 to the acceptance device N9.10. can.

Therefore, one parts feeder 1 can feed parts 2 to two receiving devices, for example the nut runner 9.1o. Furthermore, since the escape device 6 and the receiving device 9.10 are connected by the component discharge path 7.8 made of a tube, they can be installed apart from each other.

In the above-mentioned embodiment, a case was explained in which a cap nut was supplied, but the present invention can also be applied to the supply of parts such as washers and screws.

〔Effect of the invention〕

As explained above, according to the present invention, the parts supply device is provided with two escape devices, the second escape device is composed of a base and a slider that slides on the base, and the two receiving devices are Since the slider is actuated in response to a parts acceptance request to selectively supply parts to the receiving device, there is no need to provide an expensive parts feeder for each receiving device as a parts receiving device. This has the effect that it is possible to reduce the system down and also to reduce the occupied space.
