Piece feeding device for piece combiner {A Piece Feeding Apparatus for Motor-driven Driver}

The present invention corresponds to the operation of the drive unit through the switching means provided in the variable member and the drive unit when the drive unit to which the drive bit is connected relative to the variable member connected to the casing on which the piece is mounted relative to the piece It relates to a piece feeder for piece coupler to be sequentially supplied.

Generally, most of industrial products, such as household appliances, are fastened with screws so that the user can easily disassemble the product when the product is broken or cleaned. Accordingly, in the production line for mass production of industrial products, The screw fastening operation is performed using an automatic screw fastener for convenience of operation.

The automatic screw fastener includes a screw fastening unit and a screw feeding unit.

The double screw fastening unit includes a driver bit, a driving means for rotating the driver bit, and a guide rod for guiding the advancing / retreating operation of the driver bit. The screw feeding unit includes a feeding line for guiding the feeding operation of the screw, And an air supply device for supplying air to the air supply device so as to perform the feeding operation of the screw. The driving means may be a motor, a pneumatic device, or the like.

In addition, the guide rod and the feeding line are connected to a fastening head having a screw-thread-like hole formed at its end so that the screw head is caught, and the screw installed in the screw- In order to prevent the deviation of the screw that is installed in the above screw hole, the automatic screw fastener should always be in the state where the screw shaft is facing downward. When screwing the screw, So that they can be shot on both sides.

Therefore, when fastening screws through these automatic screw fasteners, first feed the screwdriver bits along the guide rods while feeding the screws to the fastening object in the state that they are fed along the feeding line, The driving means is driven.

Then, the screw is automatically rotated together with the driver bit to be fastened to the object to be fastened. Thereafter, when the screw hole is in the empty state without the screw, the air supply device is driven again, The screw fastening operation by the automatic screw fastener is performed by repeating this process.

However, in such a conventional automatic screw fastener, since the automatic screw fastener should be kept in a state where the automatic screw fastener is always facing the lower side during the screw tightening operation in order to prevent the screw installed in the screw thread main shaft from being separated, There is no point in tightening the screws, but when the posture is changed so that the screws are turned to the upper side or the side to tighten the screws from the lower side to the upper side or to tighten the screws in the lateral direction, So that the screw fastening operation can not be performed effectively.

In order to improve such a problem, the technique of the automatic screw fastener is proposed in Korean Patent Application Publication No. 2010-58020. The configuration of the automatic screw fastener is a screw fastening unit that performs a screw fastening operation as shown in FIG.

It consists of an assembly structure of the first elastic member 31c elastically supporting in the retracted direction, the end of the bit guide passage is provided with a guide rod 41 for wrapping the driver bit 13 exposed to the outside of the housing , The portion adjacent to the screw long hole 33 Between the tong members 31b of the screw support member 51 is made of a configuration that is connected.

However, the automatic screw fastener as described above causes the screw to be supplied at regular intervals regardless of the operation of the driver bit during the feeding operation of the screw S in the thread guide passage, resulting in a malfunction of the screw due to screwing. Corresponding to the bit is that the smooth supply of the piece is difficult.

An object of the present invention for improving the conventional problems as described above, to ensure the accurate supply of the piece by automation, the piece is supplied sequentially in response to the operation of the driver bit to facilitate the work, the combination of the pieces The present invention provides a piece feeder for a piece combiner that can shorten the time and adjust the feed time of the piece.

The present invention, in order to achieve the above object, the drive unit is connected to the casing to which the piece supply pipe is connected is connected via a variable member, at least a pair of jaws having a stopper in the casing can be enlarged and reduced in diameter Piece for piece coupler is installed to support and discharge the piece in a connected configuration, the switching means is provided to detect the relative movement of the drive unit with respect to the variable member to transmit a switching signal to the piece supply unit during operation of the drive unit. Provide a feeder.

In addition, the casing of the present invention provides a piece feeding device for a piece coupler in which a positioning boss protrudes to prevent contact by the jaw when the jaw rotates.

In addition, the positioning boss of the present invention provides a piece feeder for a piece coupler, the length of which is installed to extend by screwing.

In addition, the positioning boss of the present invention provides a piece feeder for a piece coupler made of a configuration in which the diameter adjusting piece is in close contact with the inside.
