[0002]

2. Description of the Related Art Generally, a work such as a round bar or a pipe is cut into a predetermined size according to a user's request. This cutting process is performed with a circular saw, a parting bite, a press, or the like. However, in the above cutting process,
A so-called burr occurs at the cutting part of the work. This burr affects the processing in the next process. Also, burrs are not preferable in terms of safety. Therefore, in recent years, the demand for deburring at the end of the work tends to increase. In addition, there are cases where it is desired to perform marking, painting, or other processing on the edge of the work. Therefore, conventionally, an end processing device such as a cutter cutting chamfering machine or an industrial robot is provided on at least one of the left and right side surfaces of a work transfer device such as a belt conveyor, and the end part of the work is clamped in a clamped state. The deburring process is performed on the.

However, in the conventional work transfer processing apparatus, when the work is clamped and transferred and at the same time the above processing is performed, it is possible to cope with a change in the length and thickness of the work. could not. This is because the clamp position of the work in the work transfer device is fixed in the conventional device. The present invention has been made in view of such conventional problems, and an object thereof is to provide a general-purpose work transfer processing device capable of coping with changes in the length and thickness of a work to be clamp-transferred.

[0004]

According to the present invention, there is provided a work transfer processing device comprising a work transfer device and an end processing device provided on at least one of both left and right side surfaces of the work transfer device for processing an end part of a work. So, the work transfer device is
It consists of a pair of left and right lower conveyors and a pair of left and right upper conveyors. The lower conveyor has a receiving attachment for loading the work, while the upper conveyor holds the work for holding it against the attachment. The lower conveyor and the upper conveyor have an attachment, and are arranged so that the receiving attachment and the pressing attachment are synchronously moved in a state of facing each other.
Further, the upper conveyor and the lower conveyor have a horizontal width adjusting mechanism for adjusting the left and right widths according to the length of the work, and the upper conveyor and the lower conveyor have a horizontal width adjusting mechanism according to the thickness of the work. A work transfer processing apparatus is characterized in that it has a vertical gap adjusting mechanism for adjusting the vertical gap.

What is most noticeable in the present invention is that the lower conveyer and the upper conveyer constitute a work transfer device, and the lower conveyer and the upper conveyer are provided with a horizontal width adjusting mechanism and a vertical gap adjusting mechanism. In the present invention, the work transfer device includes a continuous transfer type for continuous processing and an intermittent transfer type for batch processing. Further, the edge processing device is for performing processing such as deburring, engraving, painting, and labeling on the edge of the work. Further, as the deburring processing device, there are a cutter cutting chamfering machine using a cutting tool, an industrial robot for cutting that performs a motion following a work shape, a planetary brush (see FIGS. 3 and 4), and the like.

If the above planetary brush is used, it is possible to continuously convey and process the work when deburring the work, and the cycle time can be greatly shortened. In addition, it is possible to perform deburring regardless of the shape of the work. In the present invention, the left-right width adjusting mechanism may be provided independently on the upper conveyor and the lower conveyor (see FIG. 5). As a result, the left and right widths of the upper conveyor and the lower conveyor can be accurately adjusted independently of each other according to the length of the work.

Further, the above-mentioned vertical interval adjusting mechanism may be a mechanism capable of vertically moving up and down the upper conveyor at the same time (see FIG. 5).
reference). As a result, even when the diameter of the work is changed, it is possible to raise and lower the upper conveyor at the same time and adjust the interval between the two attachments to the thickness of the work by a single lifting operation. Further, the left-right width adjusting mechanism may be configured so that the upper conveyor and the lower conveyor can be simultaneously moved in the left-right direction at the same time (see FIG. 11). As a result, the upper conveyor and the lower conveyor can be moved to the left and right at the same time by a single moving operation. Also,
The vertical interval adjusting mechanism may be a mechanism that can lift the upper conveyor independently left and right (see FIG. 11). As a result, the vertical distance between the upper conveyor and the lower conveyor can be accurately adjusted independently depending on the thickness of the workpiece.

[0008]

In the present invention, when the length and thickness of the work are changed, the left and right widths of the upper and lower conveyors are adjusted by the left and right width adjusting mechanism according to the length of the work. In addition, the vertical distance between the upper and lower conveyors is adjusted by the vertical distance adjustment mechanism according to the thickness of the workpiece. As a result, the work can be firmly gripped between the receiving attachment of the lower conveyor and the pressing attachment of the upper conveyor without rattling.

Further, during conveyance, the lower conveyor and the upper conveyor move synchronously with the receiving attachment and the pressing attachment facing each other. Therefore, the work is smoothly conveyed by the work conveying device, and its end is processed. An end processing device such as a deburring machine is provided on at least one of the left and right side surfaces of the work transfer device. Therefore, the edge processing device performs processing such as deburring on the edge of the work. As described above, in the present invention, the horizontal width and the vertical distance of the upper conveyor and the lower conveyor are adjusted by the horizontal width adjusting mechanism and the vertical distance adjusting mechanism. Therefore, according to the present invention, it is possible to provide a general-purpose work transfer processing device capable of coping with changes in the length and thickness of a work.

This is for deburring.

Since the apparatus of this example is constructed as described above, it exhibits the following operational effects. That is, when the length and the thickness of the work 90 are changed, the horizontal width and the vertical interval of the lower conveyor 2 and the upper conveyor 3 are adjusted according to the length and the thickness of the work 90. In adjusting the left / right width, the left / right width adjusting mechanisms 24, 34 are used. First, the horizontal width adjustment of the lower conveyor 2 will be described. As shown in FIG. 9, the screw shaft 242 rotates by rotating the handle 241 of the left / right width adjusting mechanism 24.

As a result, the screw shaft 242
The support plate 203 of the movable conveyor 22 moves in the left-right direction through the screwing of the nut 243 with the support plate 203. At this time,

As a result, the movable frame 52 moves up and down through the screw engagement between the screw shaft 352 and the nut 353. Since the fixed conveyor 31 and the movable conveyor 32 of the upper conveyor 3 are disposed on the movable frame 52, both conveyors 31 and 32 also move up and down together with the movable frame 52. As a result, the vertical distance between the lower conveyor 2 and the upper conveyor 3 is adjusted according to the thickness of the workpiece 90.

In this way, the horizontal width and the vertical interval of the lower conveyor 2 and the upper conveyor 3 are adjusted. By this,
The receiving attachment 23 of the lower conveyor 2 and the upper conveyor 3
The work 90 can be firmly gripped between the pressing attachment 33 and the press attachment 33 without causing rattling.

0 is smoothly and continuously transferred by the work transfer device 1. At this time, the planetary brush 63 of the end processing device 6 deburrs the end of the work 90 while performing a planetary motion.

As described above, in this embodiment, the horizontal width adjusting mechanisms 24 and 34 and the vertical interval adjusting mechanism 35 adjust the horizontal width and the vertical interval of the upper conveyor 3 and the lower conveyor 2. Therefore, it is possible to easily deal with the change in the length and the thickness of the work 90. That is, the work transfer processing apparatus of this example is excellent in versatility. Further, as described above, since the deburring is performed by the planetary brush 63, a great labor saving can be achieved as compared with the conventional deburring by hand using a hand grinder. Also, the work 90
Deburring can be reliably performed regardless of the shape of the end of the. Furthermore, the deburring of both ends of the work 90 can be performed at the same time, which is efficient.

Further, the work transfer device 1 and the planetary brush 6
3, the work 90 can be continuously deburred while being continuously conveyed, so that the cycle time for deburring can be significantly shortened as compared with a conventional batch processing type cutter cutting chamfering machine. Therefore, the productivity of the work 90 can be significantly improved. Further, according to this example, the work transfer processing device can be downsized. Therefore, the equipment installation space is small.
