Description of the Related Art Conventionally, as a chip conveying conveyor device that captures and discharges chips from a turbid coolant containing chips discharged from a machine tool, a chip conveying conveyor device composed of a hinge conveyor composed of a hinge belt has been known. Yes.
[0003]
11 and 12 show an example of a conventional chip conveying conveyor device. The chip conveyor 1 'includes a hinge conveyor 4 including an endless hinge belt 3 (see FIG. 2 for the hinge belt) that circulates in a horizontal direction in the conveyor case 2, and a side chain of the hinge conveyor 4. 32 is provided with a sprocket 4a on the side of the drive unit around which the winding 32 is wound and a tail disk 4b on the side of the driven unit on which the side chain 32 slides on the conveyor tail portion T.
[0004]
In the figure, 2a is a horizontal bottom plate of the conveyor case 2, 2b is a chip discharge port provided on the chip discharge part side, and 2c is a curved part in which the conveyor case of the conveyor tail part is formed in a substantially semicircular shape. 2d is a coolant outlet formed on the side plate of the conveyor case 2, A is a turbid coolant containing large and small chips, G is an outer case, G1 is a discharge port, L is a machine tool, L1 is a main spindle, and M is a workpiece. A mounting table, N is a chip collection box.
[0005]
When the turbid coolant A mixed with large and small chips enters the conveyor case 2 from above, the chip conveying conveyor device 1 'has a large chip K1 (on the conveying hinge belt 3a running on the upper side). For example, curled chips, chips solidified in a dango shape, long chips, etc.) and some small chips K2 are captured, and these chips are conveyed to the discharge portion H side by the conveying-side hinge belt 3a. Then, it is discharged to the outside from the chip discharge port 2b and the discharge port G1. On the other hand, small chips K2 that are not captured by the conveyance-side hinge belt 3a are partially captured on the inner peripheral surface of the return-side hinge belt 3b, and the rest are settled and deposited on the horizontal bottom plate 2a of the conveyor case 2. To do.
[0006]
[Problems to be solved by the invention]
In the conventional chip conveying conveyor device 1 ', when large and small chips are mixed in the turbid coolant, as described above, the large chips K1 and some of the small chips K2 are on the conveying hinge belt 3a. The remaining small chips K2 pass through the gap between the hinge plates 31 of the conveyance-side hinge belt 3a, the gap between both ends of the hinge belt 3 and the conveyor case side wall, the gap between the side chains, and the like. A small portion of the fine chips K2 that are trapped on the inner peripheral surface of the return-side hinge belt 3b that travels below and that are not trapped also settle and accumulate on the bottom plate 2a of the conveyor case 2.
[0007]
At this time, as shown in FIG. 12, the small chips K2 captured on the inner peripheral surface of the return side hinge belt 3b are conveyed to the conveyor tail portion T, where the return side hinge belt 3b moves from the lower side to the upper side. During reverse running, the small chips K2 gradually accumulate in the space between the tail disks 4b on the inner side of the reverse part, and gradually grow to grow into a round bar-like lump K3. In this case, even if a sprocket is provided instead of the tail disk and a shaft for connecting the sprocket is provided, the tail disk is similarly enlarged and solidified.
[0008]
Thus, when the lump K3 of the chips gradually enlarges and increases, there is a problem that the hinge belt 3 is pushed up and down from the inside of the reversing part and eventually the hinge conveyor 4 is stopped. As a result, when the hinge conveyor 4 stops due to a lump of chips, there is a problem that the hinge conveyor 4 must be pulled out each time to remove the lump of chips and clean the inside. Further, since the coolant flows out from the coolant outlet 2d provided on the side plate, there is a problem that the small chips K2 accumulated on the bottom plate 2a of the conveyor case 2 cannot be discharged to the chip discharge port 2c side by the coolant flow. is there.
[0009]
As described above, in the conventional chip conveying conveyor device, there is a problem that the large and small chips contained in the turbid coolant cannot be discharged by one device. As a solution to this problem, conventionally, a scraper conveyor (small chips are not used). Although it can be carried out, large chips cannot be carried out) and a hinge conveyor (large chips can be carried out but small chips cannot be carried out) are arranged side by side or stacked in two stages. If two or more stages are stacked side by side, a large occupied space is required, and two drive sources are required, resulting in disadvantages in terms of power consumption and cost. There are problems such as poor maintainability of the conveyor.
[0010]
The conventional chip conveying conveyor device 1 'is also used for conveying dry chips mixed with large and small chips and chips adhering to the coolant, and conveying chips contained in the turbid coolant. The problem that arises in is exactly the same.
In addition, this dry swarf is a swarf which is contained in a coolant or does not contain a coolant.
[0011]
Accordingly, the present invention eliminates the problems of the prior art as described above, and in a chip conveying conveyor device using a hinge conveyor, the present invention is a small cutting device that passes through the conveying hinge belt and is captured on the returning hinge belt. By preventing the powder from staying inside the reversing part of the conveyor tail and causing the formation of chips, it is possible to prevent the hinge conveyor from stopping, and large chips are captured by the conveyor-side hinge belt. A small chip that has passed through the conveyor-side hinge belt is transported along the partition plate and discharged from the conveyor case. The purpose is to enable transporting and discharging of chips and chips with attached coolant.

[0029]
The operation of the chip conveying conveyor device 1 having the above-described configuration is as follows. When a turbid coolant containing large and small chips enters the conveyor case 2 from above, a large chip K1 is captured on the conveyor-side hinge belt 3a and conveyed to the chip discharge section H, and the conveyor-side hinge. Due to the inversion of the belt 3a, it naturally falls and is discharged from the chip discharge port 2b.
[0030]
Small chips K2 that have passed through the conveyance-side hinge belt 3a are captured on the partition plate 5. The small chips not captured here are captured on the return side hinge belt 3b (the back side of the hinge conveyor 4), and the remaining small chips K2 settle on the bottom plate 2a.
[0031]
The small chips K2 captured on the return side hinge belt 3b are conveyed to the conveyor tail part T while being placed on the return side hinge belt 3b, and the return side hinge belt 3b is reversed from the lower side to the upper side at the reverse part. In doing so, it is transferred onto the partition plate 5 along the circular member 6 while being supported by the protrusion of the hinge pipe 31 a between the hinge belt 3 and the outer peripheral surface of the circular member 6. As a result, it is possible to prevent chips from staying and clumping inside the reversing part.
[0032]
The small chips K2 transferred onto the partition plate 5 pass through the conveyance-side hinge belt 3a, and together with the small chips K2 captured on the partition plate 5, the hinge pipe 31a of the conveyance-side hinge belt 3a. It is conveyed along the partition plate 5 by the bulging, and is discharged outside the side of the conveyor case 2 by the screw conveyor 7 b of the discharge mechanism 7.
[0033]
Further, small chips settled on the bottom plate 2a of the conveyor case 2 are formed in the space formed by the tip of the side wing 36 of the hinge conveyor 4 and the bottom plate 2a, or between the side wing 36 and the side wall of the conveyor case 2. The coolant is discharged from the chip discharge port 2b by the coolant flowing on the bottom plate 2a toward the chip discharge portion.
[0034]
Furthermore, as a modification of the comparative example 1 that is helpful in understanding the present invention, as shown in FIGS. 7 and 8, an outer cleaning cleat 8 is attached to the outer peripheral surface of the hinge conveyor 4 as necessary. . There are one or two outer cleats 8 for cleaning as a whole. In this case, when the small chips K2 accumulated on the bottom plate 2a of the conveyor case 2 increase, it is transferred in the direction of the conveyor tail portion T by the cleaning outer cleat 8 and upwards along the curved portion 2c of the conveyor case. It is transported and placed on the transport-side hinge belt 3a.
[0035]
In Comparative Example 1, which is a reference for understanding the present invention, the bottom plate of the conveyor case is described as a horizontal bottom plate, but it is inclined downward from the conveyor tail portion side toward the chip discharge portion side. An inclined bottom plate may be used, or the conveyor case may be inclined such that the bottom plate is inclined downward from the conveyor tail portion side toward the chip discharging portion side. When the bottom plate is inclined, the coolant flow increases, and small chips that settle on the bottom plate can be efficiently discharged.
[0036]
Next, before explaining the chip conveying conveyor device of the present invention, a comparative example 2 which is helpful in understanding the present invention will be described with reference to FIGS.
The chip conveying conveyor device of Comparative Example 2 which is a reference for understanding the present invention is the chip conveying conveyor device 1 of Comparative Example 1 as shown in FIG. Since the inner cleat 9 having a relatively low height is attached to the surface with a relatively low height, and other configurations are not different, the operation will be described below.
[0037]
When the inner cleat 9 is attached to the inner peripheral surface of the hinge conveyor 4, small chips K2 captured on the return side hinge belt 3b when the return side hinge belt 3b reversely travels from the lower side to the upper side in the reverse part. Is conveyed upward along the outer peripheral surface of the circular member 6 while being supported by the inner cleat 9 between the hinge belt 3 and the circular member 6, and transferred onto the partition plate 5. The small chips K2 transferred onto the partition plate 5 pass through the conveyance-side hinge belt 3a, and along the partition plate 5 by the inner cleat 9 together with the small chips K2 captured on the partition plate 5. Be transported.
[0038]
Thus, by providing the inner cleat 9 on the inside of the hinge conveyor 4, the transfer of small chips on the partition plate at the reversing part and the transfer of chips on the partition plate are performed efficiently.
[0039]
When the inner cleat is provided, the partition plate is not limited to a flat plate shape, but the central portion in the width direction of the partition plate is formed in a concave shape in the longitudinal direction, and both side ends are inclined surfaces, and the chips are in the center It may be easy to shift to the part. At this time, the inner cleat is formed in conformity with the concave portion of the partition plate so as to be completely fitted. If it does in this way, it will become a thing suitable for conveyance when small chips are contained in large quantities.
[0040]
Furthermore, the cleaning outer cleat 8 is attached to the outer peripheral surface of the hinge conveyor 4 as necessary, as in the modified example of the comparative example 1 which is helpful in understanding the present invention as described above.
[0041]
The above is a description of the chip conveying conveyor device that conveys the chips contained in the coolant by mixing large and small chips as Comparative Example 1 and Comparative Example 2 which are helpful in understanding the present invention.
Therefore, the chip conveying conveyor apparatus according to the present invention uses the chip conveying conveyor apparatus 1 as described above for conveying dry chips mixed with large and small chips and chips with attached coolant. .
[0042]
That is, in the chip conveying conveyor device 1 of the present invention, when a dry chip mixed with large and small chips and a chip with coolant attached thereto are charged into the conveyor case, Comparative Example 1 as described above, Similar to 2, large chips are captured on the conveyance-side hinge belt 3a, conveyed to the chip discharge portion H, and discharged. In addition, the small chips K2 that have passed through the conveyance-side hinge belt 3a are captured by the partition plate 5, captured by the return-side hinge belt 3b, or fall on the bottom plate 2a of the conveyor case 2. As will be described, it is transported to the chip discharging part side and discharged to the outside of the side of the conveyor case 2.
[0043]
That is, the small chips captured on the return side hinge belt 3b are transferred to the partition plate 5 along the circular member 6 by the conveyor tail portion T, and together with the small chips captured on the partition plate 5. It is conveyed to the chip discharge part H side along the partition plate using the protrusion of the hinge pipe on the lower surface of the conveyance side hinge belt 3a or by the inner cleat 9, and discharged to the outside of the conveyor case 2 by the discharge mechanism. Is done.
[0044]
Further, the small chips K2 accumulated on the bottom plate 2a of the conveyor case 2 are transferred to the conveyor tail portion T side when the outer cleaning cleat 8 provided on the outer peripheral surface of the hinge conveyor 4 is provided, The sheet is placed on the conveyance-side hinge belt 3a by reversing the return-side hinge belt 3b.
[0045]
As mentioned above, although the Example of the chip conveyance conveyor apparatus of this invention was described, it replaces with a screw conveyor as a discharge mechanism 7 which discharges | emits the small chip conveyed along the partition plate, and uses a coil conveyor. Good. The drive mechanism of the discharge mechanism 7 may be independently driven by a separately provided motor, for example, a gear motor, a hypoid gear motor, or the like instead of using the side chain of the hinge conveyor as in the first comparative example.
[0046]
Also, without providing a screw conveyor, coil conveyor, etc., on the chip discharge part side, a concave ridge that slopes downward toward the outer side of the conveyor case is provided at the end of the partition plate. A bowl-shaped chute that is inclined obliquely downward may be connected, and small chips may be slid down into the chip collection box N.
[0047]
Moreover, although the thing using the plain plate without a through-hole as a hinge plate was demonstrated, the perforation plate with a through-hole, the dimple plate with a protrusion may be used, and these may be used in multiple types of combination. The hinge plate is preferably made of steel, but may be made of plastic.
[0048]
Further, as a form of the conveyor tail portion T in which the hinge belt reversely travels, as shown in FIG. 1, the hinge belt travels around the tail disk 180 ° around the reversing portion, and the conveyance side hinge belt and the return side hinge belt In addition to the configuration in which the hinge belt is in a parallel state, the hinge belt travels around the tail disk at 180 ° or more in the reversing part, rises up in a mountain, then falls, and the conveyance side hinge belt and the return side hinge belt It is good also as a thing of the form used as a parallel state (refer FIG. 11, FIG. 12).
[0049]
【The invention's effect】
As described above, the chip conveying conveyor device according to the present invention is provided with a partition plate in the longitudinal direction on the lower side of the conveying-side hinge belt that runs on the upper side, in close proximity to the conveying-side hinge belt. Therefore, the small chips that have passed through can be captured by the partition plate without being captured by the conveyance-side hinge belt.
[0050]
Since a circular member is provided across the width direction inside the reversing part where the return hinge belt reversely travels from the lower side to the upper side on the conveyor tail side, small chips captured on the return side hinge belt Can be transferred along the circular member at the conveyor tail portion onto the partition plate using a hinge belt. As a result, it is possible to prevent the occurrence of a lump of chips inside the reversing part, and thus it is possible to prevent the conveyor from being stopped due to clogging of the chips and to reduce the frequency of maintenance.
[0051]
On the lower side of the conveyor-side hinge belt running on the upper side, a partition plate is provided in the longitudinal direction in close proximity to the conveyor-side hinge belt. The small chips made and the small chips captured on the partition plate can be conveyed along the partition plate to the chip discharge section side using the inner peripheral surface of the hinge conveyor.
[0052]
Also, if the inner cleat is not provided on the inner peripheral surface of the hinge conveyor, if the inner cleat is attached to the inner peripheral surface of the hinge conveyor due to the protrusion of the hinge pipe that is the connecting part of the hinge plate The small cleat trapped on the return side hinge belt can be transferred onto the partition plate along the circular member by the inner cleat, and the transported small chips and small trapped on the partition plate can be transferred. Chips can be conveyed along the partition plate.
[0053]
Since the discharge mechanism that discharges small chips conveyed along the partition plate to the outside of the side of the conveyor case is provided at the end of the partition plate on the chip discharge part side, the transfer-side hinge belt and the return-side hinge From between the belts, small chips can be discharged outside the side of the conveyor case.
[0054]
As described above, according to the present invention, it is possible to convey and discharge dry chips mixed with large and small chips and chips adhering to the coolant in one chip conveying conveyor device. Thus, a large occupied space is not required unlike a conveyor device in which two types of conveyors are arranged side by side or stacked in two stages, and the occupied space of the chip conveying conveyor device can be reduced.
