Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a device relating to a parts take-out mechanism in an assembling parts quantitative feeder used in the field of assembling automobiles and various other products.

[0002]

[Prior art]

 Conventionally, for example, metal or synthetic resin washers and nuts used for assembling various products were taken out from a container that contained a large number of them by one finger at the time of assembly work. Since the nuts are flat and the polygons are small, and they are all housed in a compact and overlapping state, it is harder for the worker to pick up the parts because the worker wears gloves, and even if picked, the assembly work It is necessary to pick up more than the required number and return the excess to the container, or if the number is insufficient, take the duplicate work of removing the required number from the container again. It wasn't. For this reason, the work efficiency is poor, and when the parts are particularly small or thin, or when the parts are made of synthetic resin and are lightweight, the adverse effects thereof are remarkable.

In order to solve this problem, a method of giving a slight vibration to a container accommodating parts, a method of raising and lowering a part accommodating portion by a cylinder at a place where parts are accumulated in the container, or a part is placed There was a parts feeder that discharges parts one by one from the container by making the container close to a sealed state and injecting air from the lower side of one side of the container.

[0004]

[Problems to be solved by the device]

 However, even in these parts feeders, parts are discharged from the container continuously or, conversely, intermittently, so that the parts are supplied to the assembly worker and the product is assembled by the worker. There was a problem that the time coordination with the work was not smooth.

[0007] The present invention is intended to provide a mechanism for supplying the parts discharged from the container in the assembling parts constant amount feeder to the hands of the assembling operator at the necessary time and in the required number. Is.

[0006]

[Means for Solving the Problems]

 The present invention relates to an assembling component constant quantity feeder for continuously discharging a fixed amount of a part (a) from the inside of the container 1 by vibration, an elevating mechanism or a jet airflow, in a discharge port of the container 1. 2 is connected to a guide body 3 which is inclined downward toward the assembly worker side (b), and the guide body 3 has a width in which each discharged part (a) can be rolled in an upright state. (S) and a guide path 3a is opened at least above the terminal end 4b, and the starting end 3b of the guide path 3a is communicated with the discharge port 2 and is guided to the guide body 3 near the terminal end 3c of the guide path 3a. The center part of the escape wheel 4 is pivotally supported so that it can be reciprocally rotated. The hook portion 4a at the front end of the escape wheel 4 faces the guide path 3a freely, and the stopper 4b at the rear is guided. The outlet 3d of the passage 3a is opened and closed, and the weight 5 is attached to the stopper 4b via the finger hook 4c.

[0007]

【Example】

 FIG. 1 is a perspective view of one embodiment of an assembling parts constant quantity feeder having a parts taking out mechanism of the present invention, in which 1 is a container for accommodating parts (a) for assembling products such as washers or nuts. Then, in this container 1, a funnel-shaped accumulating portion 6 which is the accumulating place of the component (a), a gas ejection mechanism 7 provided at the lower bottom portion of the accumulating portion 6, and an ejection from the gas ejection mechanism 7 are carried out. A guide part 8 is provided for guiding the part (a) blown up by the generated air flow to the discharge port 2 of the container 1.

Reference numeral 3 denotes a guide, which is attached to the discharge port 2 of the container 1 while being inclined downward toward the assembly operator side (b). The guide body 3 has a width (s) slightly larger than the wall thickness (t) of the part (a) continuously discharged from the discharge port 2 of the container 1 and opened at least above the terminal end 3c. A guide path 3a is bored along the longitudinal direction, and a starting end 3b of the guide path 3a is communicated with the discharge port 2.

On a side portion 3e of the guide body 3 near the end 3c of the guide path 3a, a supporting leg 9 is provided so as to project upward, and a downward U-shaped escape wheel 4 is provided at an upper end of the supporting leg 9. The central portion of the shaft is rotatably supported by a shaft 10 so that the hook portion 4a at the front end can freely move in and out of the guide passage 3a, and continuously rolls in the guide passage 3a. Among the multiple parts lined up in, the length and angle are suitable for cutting in between the first part (a) and the next part (a). Further, the stopper 4b at the rear portion is formed with a length and an angle capable of opening and closing the outlet 3d of the terminal end 3c of the proposed path 3a as the escape wheel 4 rotates, and when it is not necessary to take out parts, the stopper 4b is the outlet. A weight 5 for rotating the escape wheel 4 is provided so that the closed state of 3d can be maintained.

The hook portion 4a of the escape wheel & pinion 4 in the embodiment is formed to have a length and an angle suitable for taking out one part (a) from the outlet 3d. Depending on the contents of the assembling work, two or more than two parts may be formed at a length and angle so that they can be taken out from the outlet 3d at a time. In the figure, a 7ah compressor, 7b are air switching valves, and 7c is an ejection hole.

[0011]

[Function of the device]

 Since the present invention is configured as described above, the stopper 4b of the escape wheel 4 normally closes the outlet 3d of the guideway 3a due to the weight of the weight 5, and the component emitted from the outlet 2 of the container 1 is Roll one by one and line up in the guide path 3a.

When parts are needed, the finger rests 4c of the escape wheel 4 are lifted against the weight of the weight 5 by hanging the fingertips on the finger rest portion 4c of the escape wheel 4, and the escape wheel 4 rotates about the shaft 10. The hook portion 4a moves between the earliest washer and the subsequent washer which are the parts (a). At the same time, the stopper 4b opens the outlet 3d, so that only the earliest washer falls on the palm of the hand that operated the finger rest 4c.

Meanwhile, the subsequent washers (a), (a) ... Are prevented from rolling by the hook portion 4a and remain in the guide path 3a. When the finger is released from the finger rest 4c, the escape wheel 4 is rotated by the weight of the weight 5 and the hook 4a is displaced upward, so that the blocked washer (a) is rotated. Although it reaches the outlet 3d, the load of the weight 5 closes the outlet 3d. After that, the washers can be taken out one by one by the same operation as described above to hold the plurality of washers in the guide passage 3a.

[0014]

[Effect of device]

 Therefore, according to the present invention, when the escape wheel is rotated by the fingertips, the parts are automatically ejected. Therefore, it is easy and reliable to take out small parts of this kind, and at the same time, the operation is repeated. Since the parts can be received by the palm of the same hand as when operating the escape wheel, the other hand can be used for assembly work and the parts can be received with one hand. Together, they can further improve the efficiency of assembly work. The subsequent parts are securely retained in the guide path and do not drop, and do not hinder the progress of the work.
