The present invention relates to a device for automatically supplying a work, which is used when, for example, automatically supplying a large number of raw pipes accommodated in a raw pipe storage frame to a intermittent pipe drive type raw pipe supply conveyor.

2. Description of the Related Art For example, in a photosensitive drum of an electronic copying machine, a laser printer, or the like, a photosensitive drum substrate that supports a photoconductive photosensitive layer is often manufactured by piercing one end of a long aluminum extruded raw pipe. After processing, this is subjected to drawing processing, straightening is performed, then this is cut into specified length units, chips are washed, and finally end face processing is performed. It is being appreciated.

Then, the present applicant has recently fully automated the above-mentioned processes from the process of forming the extrusion extrusion raw pipe to the processing of the end face, and also automates the delivery of the work between the processes, thereby making it possible to automatically We have developed and put into practical use a photosensitive drum substrate automatic manufacturing facility that allows the photosensitive drum substrate to be automatically sent out sequentially from the final take-out line if the extrusion pipes are sequentially supplied to the raw pipe supply / conveyor.

However, on the other hand, even in this automated facility, the supply of the drawing raw pipe to the raw pipe supply conveyor of the automatic mouthpiece processing apparatus still requires manual labor.

That is, the extruded raw pipe to be drawn is generally manufactured in an extrusion equipment installed in a building different from the building in which the photosensitive drum substrate automatic manufacturing equipment as described above is installed. After that, in a state in which a large number of the styrene spacers (2) are accommodated in a horizontal parallel laminated state using a styrene spacer (2) as shown in FIG. It is carried to the real frame stockyard adjacent to. Then, when manufacturing the photosensitive drum substrate, the actual frame (3) is moved by a forklift.

It is possible to manufacture the photosensitive drum substrate with high yield without causing scratches or the like.

Further, since the apparatus of the present embodiment is arranged by arranging the actual frame transfer line (8) and the empty frame transfer line (12) vertically, the installation space of the apparatus may be small, and the actual frame Since the supply position of (3) and the take-out position of the empty frame (6) coincide with each other, there is an advantage that a work space for performing both works can be reduced.

Moreover, in addition to the arrangement of the two lines (8) and (12) in the vertical direction, the real frame elevating device (44) for taking out the work arranged at the work taking out station (7) is provided to the real frame feeding means (9). By adopting a configuration that also serves as each component of the empty frame delivery means (11), the device configuration can be simplified.

In addition, the actual frame transfer line (8) is placed at the bottom, the empty frame transfer line (12) is placed at the top, and the pedestal (46) is at the height position of both lines (8) and (12) for taking out the raw pipe. Since it is supposed to be raised intermittently between spaces, the pedestal (46) is moved to the height position of the empty frame transfer line (12) after the empty tube (4) is taken out. The working time can be shortened, and the empty frame (6) and the real frame (3) can be quickly replaced in the work picking station (7).

Further, the work take-out supply device (10) is configured to include an intermediate transfer device (40), and an air blow device (73) is provided in the transfer path of the raw pipe (4) by the transfer device (40). ) Is provided, it is possible to supply the raw pipe (4) from which foreign substances such as dust and dust causing scratches are removed to the processing device side, and it is possible to improve the manufacturing yield of products. it can.

The work supplied by the device of the present invention is not limited to the drawing raw pipe, and includes a pipe or rod-shaped work for various purposes.

EFFECTS OF THE INVENTION As described above, in the work automatic feeder according to the present invention, the worker supplies the real frame that accommodates a large number of works in the horizontal parallel stacked state to the real frame transfer line, and the empty frame transfer line. Since the work is automatically automatically supplied to the work receiving side simply by performing the work of removing the empty frame from the work receiving side, the work load on the worker can be reduced and the work stability can be improved. it can.

Moreover, since the work can be supplied to the work receiving side without touching the operator's hand by using this work automatic supply device, the surface quality particularly used for manufacturing the photosensitive drum substrate is strictly required. It is possible to supply the work to various processing apparatuses without damaging the work.

Also, since the actual frame transfer line and the empty frame transfer line are arranged side by side vertically, the installation space for the device may be small, and the supply position of the actual frame and the take-out position of the empty frame match. By doing so, the work space for performing both works can be reduced, and both works can be performed at the same place, so the labor burden can be reduced.

Further, the real frame elevating device (44) is provided in the work take-out supply device (10) of the work take-out station corresponding to the above-mentioned arrangement configuration of both lines (8) (12), and the real frame (3)
The pedestal on which is mounted is to be moved up and down between the height position of the exit of the actual frame transfer line and the height position of the entrance of the empty frame transfer line located above it. Since the pedestal is intermittently lifted so that the work on the frame can be taken out sequentially from the upper one by a work transfer device at a predetermined height position, the work can be taken out from the actual frame. After finishing, it is possible to shorten the time to move the empty frame to the height position of the empty frame transfer line by raising the pedestal, which in turn shortens the time required to replace the empty frame with the actual frame at the work picking station. Therefore, the work can be efficiently supplied without a break.
