The trays 50 are movably disposed on the first platform 35 or the second platform 45. Although FIG. 1 only shows one tray 50, in fact, the trays 50 can be stacked vertically on the tray. As shown in FIG. 4, the first support 35 or the second support 45 each has four positioning holes 52 and positions corresponding to the four positioning posts 254 on the clamping member 253, in this embodiment In the process, the trays 50 can be moved into or out of the first platform 35 by the rollers 351 of the first platform 35. Similarly, the trays 50 can be accessed by the second platform 45 The roller 451 enters or leaves the second platform 45 movably. In other possible embodiments, the rollers 351, 451 can be replaced with other elements with similar functions, as long as they can move the trays 50 into or out of the first bearing 35 or the second bearing Taiwan 45 is enough.

The following describes the steps of the circulating feeding of the circulating feeder 10, please refer to Figures 1 to 4.

First, the first motor 34 of the feeding system 30 drives the first interlocking device 33, so that the first interlocking device 33 simultaneously drives the two first screws 32 to rotate, and the first platform 35 receives the two first The screw 32 is driven to rise along the first guide rods 31, and the trays 50 on the first platform 35 rise together until the first tray 50 on the top is exposed to the first The opening 23 is substantially horizontally aligned with the sliding frame 252, and then the positioning posts 254 on the four clamping members 253 respectively extend into the four positioning holes 52 on the tray 50, so that the tray 50 is fixed, and the tray 50 The material on can be processed.

After the first tray 50 on the first platform 35 finishes the processing operation, the first motor 34 drives the first interlocking device 33 and drives the two first screws 32 to rotate, so that the first platform 35 And the other trays 50 on the first platform 35 are lowered to a predetermined position. At this time, the first tray 50 is still positioned by the positioning posts 254 and will not descend. Then, the sliding frame 252 slides on the two slide rails 251 sandwiching the first tray 50 until the first tray 50 is displaced to the second opening 24, at the same time, the second motor 44 of the discharge system 40 drives The second interlocking device 43 causes the second interlocking device 43 to synchronously drive the two second screws 42 to rotate, so that the second platform 45 is driven by the two second screws 42 to follow the second guides The guide rod 41 rises until the second platform 45 abuts against the bottom edge of the first tray 50, and then, the positioning posts 254 on the four clamping members 253 are retracted away from the four positioning holes 52, so that the first The material tray 50 is no longer positioned, the second motor 44 drives the second linkage 43, and the two second screws 42 are driven to rotate, so that the second platform 45 and the second platform 45 located on the second platform 45 One tray 50 is lowered. In this case, the circulating feeder 10 makes the first tray 50 complete the feeding operation and the discharging operation together.

After the first tray 50 completes the above steps, the sliding frame 252 slides from the second opening 24 to the first opening 23, and then the circulating feeder 10 repeats all the above steps again, so that the second The tray 50 is similar to the first tray 50 to complete the feeding operation and the discharging operation. It is understandable that the second tray 50 located on the second platform 45 of the discharging system 40 is stacked on the first tray 50 One tray 50, and so on.

In this way, the circulating feeder 10 can circulate the feeding operation and the discharging operation of the material. Compared with the conventional structure, the feeding and discharging efficiency of the processing operation can be effectively improved.

Please refer to FIG. 5, which is a lathe processing system 60 provided by a preferred embodiment of the present invention, which includes a circulating feeder 10, a tray feeding device 70, and a lathe processing machine 80 as described above. The tray picking and sending device 70 is used to feed the trays 50 before processing into the feeding system 30, or to send the trays 50 after processing away from the discharging system 40, that is, The material tray feeding device 70 can make the material trays 50 enter the first platform 35 through the rollers 351 to start the feeding operation, and can also make the material trays 50 leave the first tray 35 through the rollers 451 The second platform 45 ends the discharging operation. When the trays 50 are moved by the feeding system 30 and exposed to the first opening 23, the lathe processing machine 80 starts to process the materials on the trays 50.

Please refer to the axial schematic diagrams in Figs. 2 and 5. In this embodiment, the tray feeding device 70 feeds the trays 50 in or out of the circulating feeder 10 in the Z-axis direction. A support 35 and the second support 45 are raised or lowered in the Y-axis direction, and the sliding frame 252 is slid between the first opening 23 and the second opening 24 in the X-axis direction.

More specifically, the trays 50 are fed into the first platform 35 in the Z-axis direction by the tray-taking device 70, and then rise to the first platform 35 in the Y-axis direction by the first platform 35 The opening 23 is positioned by the four clamping pieces 253 for the lathe processing machine 80 to perform a processing operation, and the lathe processing machine 80 performs processing operations on the materials on the tray 50 one by one in the Z-axis direction, each time a row of Z is completed In the machining of the material in the axial direction, the sliding frame 252 drives the material tray 50 to move toward the second opening 24 by a predetermined distance in the X-axis direction, so that the lathe processing machine 80 can process the next discharge material, thereby By analogy, until all the materials on the tray 50 complete the processing operation, the sliding frame 252 continues to drive the tray 50 to move in the X-axis direction to the second opening 24, and then the Y The axis direction is lowered, and finally the tray take-out device 70 sends the trays 50 away from the second platform 45 in the Z-axis direction, thus completing a complete feeding and discharging cycle. When the tray feeding device 70 feeds the tray 50 into the first platform 35, a sensor (not shown) on the first platform 35 can sense whether the predetermined tray 50 is all Enter the first platform 35, if it is, the first platform 35 will start to rise; in addition, when the trays 50 rise, a sensor (not shown) on the sliding frame 252 can sense When the first tray 50 has risen to the position of the first opening 23 and is horizontally aligned with the sliding frame 252, if so, the first platform 35 stops rising, and at the same time, the positioning column on the four clamping members 253 254 extends into the four positioning holes 52 on the tray 50 to position the first tray 50, and the lathe processing machine 80 starts processing.

In fact, in other possible embodiments, the structure of the sliding device 25 can be changed as required, as long as it can move the trays 50 from the first opening 23 to the second opening 24; the trays The number of 50 is not limited, and it can be a single one or more than two stacked on top of each other; the position of the two first screws 32 is not limited to the position between the two first guide rods 31, the same is true for the two second screws 42 The position of is not limited to the position between the two second guide rods 41, but the position of the first screw 32 and the second screw 42 of the above embodiment can make the feeding system 30 and the discharging system 40 The structure is more stable; the number of the positioning holes 52 and the positioning posts 254 can be changed according to requirements, and even the structure and the manner in which the sliding frame 252 positions the trays 50 can have other changes, which is not particularly limited here.

It must be noted here that the detailed description given above with reference to the drawings is only an embodiment provided to illustrate the technical content and features of the present invention. Those who have general general knowledge in the field of the present invention will understand the technical content of the present invention. After the features and features, all kinds of simple modifications, replacements or component reductions without departing from the spirit of the present invention shall fall within the protection scope of the patent application scope disclosed by the present invention.
