Further, on the outer peripheral surface of the liquid receiving cup 53, there is provided a belt hooking concave portion 54 having a concave arc cross section along the circumferential direction of the liquid receiving cup 53. The belt hooking recess 54 is provided at a position near the lower end of the outer peripheral surface of the liquid receiving cup 53. Further, a discharge port 55 for discharging the cutting fluid that has flowed into the liquid receiving cup 53 is provided at the center of the bottom surface of the liquid receiving cup 53. Below the discharge port 55, a liquid receiving tank (not shown) for receiving and collecting the cutting fluid received by the liquid receiving cup 53 and discharged from the discharge port 55 is installed.

  Furthermore, a bottomed substantially cylindrical bucket 61 as a collection device is attached in the liquid receiving cup 53. The bucket 61 is detachably attached to the liquid receiving cup 53, that is, detachably attached. Therefore, the bucket 61 is formed in a picture-bottomed cylindrical shape having an outer dimension slightly smaller than the inner diameter dimension of the liquid receiving cup 53 and a height dimension larger than the height dimension of the liquid receiving cup 53. Further, the bucket 61 can rotate in the circumferential direction together with the liquid receiving cup 53 by rotating the liquid receiving cup 53 in the circumferential direction. In the bucket 61, the chips separated by the separator 31 and flowing down together with the cutting fluid fall from the base end edge of the separation plate 32 of the separator 31 and are supplied. Here, as shown in FIGS. 1 and 2, the bucket 61 is supplied with chips falling from the base end edge of the separation plate 32 of the separator 31 at a position closer to the outer periphery than the central portion of the bucket 61. Is attached in position.

  Specifically, as shown in FIG. 4, the bucket 61 has a bottom plate body 62 as a mortar-shaped accumulation portion having a conical shape in which the center portion is most depressed. The bottom plate body 62 is provided at the bottom of the bucket 61. Then, on the bottom plate 62, the chips supplied together with the cutting fluid are deposited and accumulated in the bucket 61, and the chips are separated from the cutting fluid. A cylindrical body 63 as a cylindrical drainage part is attached to the outer peripheral edge of the bottom plate body 62. The cylindrical body 63 is formed on the peripheral surface portion of the bucket 61, and allows the cutting fluid supplied together with the chips into the bucket 61 to be discharged to the outside of the bucket 61. Further, the lower end, which is one end in the axial direction, of the cylindrical body 63 is closed by the bottom plate body 62 to form the bucket 61.

  In addition, the cylindrical body 63 is configured by rounding an elongated rectangular flat plate punching plate in which liquid draining holes 64 as a plurality of holes are formed at equal intervals, and connecting both end edges to each other. That is, the cylindrical body 63 discharges the cutting fluid supplied together with the chips into the bucket 61 from the plurality of liquid drain holes 64 of the cylindrical body 63 into the liquid receiving cup 53 outside the bucket 61. Let Here, the upper end edge of the cylindrical body 63 protrudes upward from the upper end edge of the liquid receiving cup 53 in a state where the bucket 61 is installed on the liquid receiving cup 53.

  Further, a plurality of concave notch recesses 65 are provided at the lower end edge of the cylindrical body 63 for allowing the cutting fluid discharged from the plurality of liquid discharge holes 64 of the cylindrical body 63 to flow into the discharge ports 55 of the liquid receiving cup 53. Is formed. For example, about six of these notch recesses 65 are provided at regular intervals in the circumferential direction of the cylindrical body 63. Here, when the bucket 61 is accommodated in the liquid receiving cup 53, these notched recesses 65 are engaged with the bottom surface of the liquid receiving cup 53 and rotate the bucket 61 together with the liquid receiving cup 53.

  On the other hand, a motor 71 as a driving means for rotating the bucket 61 together with the liquid receiving cup 53 is attached below the installation plate 52 on the other end side from the liquid receiving cup 53. The motor 71 rotationally drives a pulley 72 as a rotating shaft that protrudes from below the installation plate 52 toward the upper side of the installation plate 52. The pulley 72 and the belt-hanging recess 54 of the liquid receiving cup 53 are wound with the central portion of the belt body 73 that is an endless endless body intersecting. Therefore, the motor 71 rotates the belt body 73 by rotating the pulley 72 with the motor 71, whereby the liquid receiving cup 53 rotates with the belt body 73, and the bucket 61 in the liquid receiving cup 53 is rotated. Rotate.

  That is, the motor 71 rotates the bucket 61 together with the liquid receiving cup 53, and moves and averages the inflow positions of the cutting fluid and the chips into the bucket 61. The motor 71 is connected to a controller as a control means (not shown) that can control the rotation of the motor 71. The motor 71 is configured so that the rotation speed of the bucket 61 can be operated in two stages of a low speed and a high speed under the control of the controller. Specifically, the motor 71 rotates the bucket 61 at a low speed under the control of the controller when the cutting fluid is separated from the chips supplied to the bucket 61. Further, the motor 71 is configured to drive the bucket 61 at a high speed by the control of the controller immediately after the separation of the cutting fluid from the chips in the bucket 61 is completed and immediately before the chips are discarded from the bucket 61. By rotating, the cutting fluid adhering to the bucket 61 is discharged to some extent by centrifugal force.

  Further, the liquid receiving cup 53 is attached so as to be movable along the longitudinal direction of the installation plate 52. That is, when the bucket 61 installed in the liquid receiving cup 53 is removed from the liquid receiving cup 53, the upper end edge of the cylindrical body 63 of the bucket 61 is the base end edge of the separator 31. In order not to be caught by the mounting plate 52, the mounting plate 52 is attached so as to be movable toward the other end side.

  The installation plate 52 is provided with a lock mechanism 74 as a fixing means for rotatably fixing the liquid receiving cup 53 in a state where the liquid receiving cup 53 is moved to the separator 31 side. As shown in FIGS. 1 and 2, the lock mechanism 74 includes a pair of lock levers 75 attached to both sides of the pulley 72 on the installation plate 52. Here, the lock mechanism 74 allows the liquid receiving cup 53 to move toward the other end side of the installation plate 52 by opening each of the lock levers 75. Further, the lock mechanism 74 can rotate the liquid receiving cup 53 by closing each of the lock levers 75 in a state where the liquid receiving cup 53 is moved toward one end of the installation plate 52. Secure and lock.

  Next, the operation of the first embodiment shown in FIGS. 1 to 4 will be described.

  First, if the cutting fluid used for cutting in the cutting unit contains a certain amount of chips generated by the cutting in this cutting unit, collect the cutting fluid in the recovery tank and And supplied to the supply port 3 of the storage tank 2 of the chip separation device 1, and stored in the storage tank 2.

  In this state, the motor 22 is driven to rotate the rotating shaft 23 and the magnet drum 11 is rotated counterclockwise in FIG. 1 via the chain 24 and the cutting fluid stored in the storage tank 2 It is extracted from the discharge port 4 of the storage tank 2 by a pump and supplied to each spray nozzle 41.

  Furthermore, the motor 71 of the chip collection device 51 is driven to rotate the pulley 72 at a low speed, and the bucket 61 is rotated at a low speed together with the liquid receiving cup 53 via the belt body 73.

  At this time, chips in the cutting fluid stored in the storage tank 2 are adsorbed to the outer surface of the magnet sheet 15 attached to the outer peripheral surface of the magnet drum 11. Then, the chips adsorbed on the outer surface of the magnet sheet 15 rotate with the rotation of the magnet drum 11 while adsorbed on the outer surface of the magnet sheet 15.

  Thereafter, the chips are scraped off at the leading edge of the separation plate 32 of the separator 31 by the rotational force of the magnet drum 11 and collected from the outer surface of the magnet sheet 15 of the magnet drum 11.

  Then, the chips collected at the leading edge of the separation plate 32 of the separator 31 are directed from the distal end side to the proximal end side on the separation plate 32 of the separator 31 by the cutting fluid sprayed from each spray nozzle 41. It is flowed together with the cutting fluid and supplied into the bucket 61 of the chip collection device 51.

  At this time, as the bucket 61 rotates, the supply position of the cutting fluid and the chips to the bucket 61 continues to change in the circumferential direction. Accordingly, the chips are supplied to the bucket 61 in a substantially uniform manner together with the cutting fluid.

  Thereafter, the chips supplied together with the cutting fluid into the bucket 61 are deposited and deposited on the bottom plate body 62 of the bucket 61. Further, the cutting fluid supplied into the bucket 61 together with the swarf is discharged to the outside from the liquid draining hole 64 of the cylindrical body 63 of the bucket 61 and received by the liquid receiving cup 53.

  Then, the cutting fluid received by the liquid receiving cup 53 is discharged from the discharge port 55 of the liquid receiving cup 53 through the notch recess 65 of the bucket 61, and is installed below the discharge port 55. It is collected in the receiving tank.

  Thereafter, when a predetermined amount of chips accumulates in the bucket 61, the rotation of the magnet drum 11 of the chip separating device 1 is stopped and the spraying of the cutting fluid by each spray nozzle 41 is stopped.

  Next, the bucket 71 is rotated at a high speed together with the liquid receiving cup 53 by the motor 71 of the chip collection device 51, and the cutting liquid adhering to the bucket 61 is discharged to some extent by centrifugal force, and then the motor 71 is stopped. Thus, the rotation of the liquid receiving cup 53 and the bucket 61 is stopped.

  In this state, each lock lever 75 of the lock mechanism 74 of the chip collecting device 51 is opened to allow the liquid receiving cup 53 to move toward the other end side of the installation plate 52.

  Thereafter, the bucket 61 is moved to the other end side of the installation plate 52 together with the liquid receiving cup 53, and then the bucket 61 is removed from the liquid receiving cup 53.

  Then, the chips accumulated in the bucket 61 are removed manually.

  Thereafter, after the bucket 61 from which the chips have been removed is installed in the liquid receiving cup 53, the bucket 61 is moved toward the one end side of the installation plate 52 together with the liquid receiving cup 53.

  In this state, each lock lever 75 of the lock mechanism 74 is closed, and the liquid receiving cup 53 is rotatably fixed on the installation plate 52 and locked.

  Thereafter, the magnet drum 11 of the chip separating device 1 is rotated, the cutting fluid is sprayed from each spray nozzle 41, and the liquid receiving cup 53 of the chip collecting device 51 is further rotated to be stored in the storage tank 2. The work of collecting chips from the cutting fluid is started.

  As described above, according to the first embodiment, when the magnet drum 11 is rotated, chips in the cutting fluid stored in the storage tank 2 are removed from the magnet sheet 15 on the outer peripheral surface of the magnet drum 11. The chips adsorbed on the magnet sheet 11 are scraped off and collected at the front edge of the separation plate 32 of the separator 31. At this time, the cutting fluid stored in the storage tank 2 is sprayed from each spray nozzle 41 toward the portion where the chips are scraped off and collected by the separation plate 32 of the separator 31, and the separation plate 32 The chips collected in step 1 were washed away with cutting fluid.

  As a result, the chips collected by the separation plate 32 of the separator 31 do not accumulate in a large amount at the leading edge of the separation plate 32 or spill out from the side plates 33 on both sides of the separation plate 32. By spraying the cutting fluid by each spray nozzle 41, the chips collected by the separation plate 32 can be flowed into the bucket 61 of the chip collecting device 51 together with the cutting fluid. At the same time, since the cutting fluid stored in the storage tank 2 is branched and sprayed from the spray nozzle 41, the cutting liquid stored in the storage tank 2 is contained in the cutting liquid without being diluted. Chips can be collected. As a result, the chips contained in the cutting fluid stored in the storage tank 2 can be efficiently collected and recovered from the cutting fluid.

  Further, the chips collected at the leading edge of the separation plate 32 of the separator 31 are accumulated at a position closer to the base end side than the leading edge of the separation plate 32 by continuously collecting the chips. Therefore, the cutting fluid is sprayed from each spray nozzle 41 toward the position closer to the base end side than the distal end edge of the separation plate 32. As a result, the chips collected by the separation plate 32 flow more efficiently together with the cutting fluid to the bucket 61 of the chip collection device 51. Therefore, the chips collected by the separation plate 32 are more efficiently It can be well collected and collected in the bucket 61 of the chip collection device 51.

  Further, the inner diameter dimensions of the spray ports 42 of each of the spray nozzles 41 were made larger than the average size of general chips contained in the cutting fluid stored in the storage tank 2. As a result, even if the cutting fluid stored in the storage tank 2 is branched and sprayed from the spray nozzles 41, the spray ports 42 of the spray nozzles 41 are not easily clogged with chips. Therefore, it is possible to prevent clogging due to chips of the spray ports 42 of the spray nozzles 41.

  Further, by supplying the chips separated by the separator 31 of the chip separating apparatus 1 into the bucket 61 of the chip collecting apparatus 51, the chips are deposited on the mortar-shaped bottom plate body 62 of the bucket 61. The cutting fluid that accumulates and flows into the bucket 61 together with the chips is discharged from the drain hole 64 of the cylindrical body 63 of the bucket 61 to the liquid receiving cup 53. As a result, the chips separated from the cutting fluid can be separated efficiently from the cutting fluid simply by flowing the cutting fluid from the spray nozzle 41 and supplying it into the bucket 61. Can be recovered.

  Further, the liquid receiving cup 53 in which the bucket 61 is installed is rotated, and the bucket 61 is rotated together with the liquid receiving cup 53. As a result, the supply position of the cutting fluid and the chips from the separator 31 to the bucket 61 changes at any time in the circumferential direction of the bucket 61, so that these chips and the liquid can be uniformly supplied into the bucket 61. Therefore, the chips can be deposited and averaged in the bucket 61 on average, so that the chips can be separated and recovered more efficiently from the cutting fluid.

  Further, as in the second embodiment shown in FIG. 5, the separator 31 has a concave U-shaped groove structure, and an elongated cylindrical pipe 81 as a spraying means is attached to the tip edge of the separator 31, A plurality of, for example, four spray ports 42 may be opened in the pipe 81. In this case, the spray ports 42 are provided at equal intervals in the axial direction of the pipe 81. Furthermore, one end of the pipe 81 is closed, and the cutting fluid is sprayed onto the separator 31 from each spraying port 42 of the pipe 81, so that the chips accumulated on the separator 31 flow. .

  As a result, the configuration is such that the cutting fluid is discharged from the spray port 42 provided in the pipe 81 and sprayed onto the separator 31, thereby providing the same operational effects as the first embodiment and the spray nozzle 41. Compared with the case where the cutting fluid is sprayed onto the separator 31 from the spraying port 42, the spraying port 42 is less likely to be clogged by the chips contained in the cutting fluid. Further, even if any one of these spray ports 42 is clogged, the flow of the cutting fluid on the separator 31 is more difficult due to the spraying of the cutting fluid from the other spray ports 42. Therefore, the cutting fluid can flow over the entire separator 31 for a longer period of time.

  In each of the above embodiments, the magnet sheet 15 is attached to the outer peripheral surface of the magnet drum 11. However, the magnet sheet 15 is attached to at least a part of the outer peripheral portion of at least one side surface of the magnet drum 11, and the magnet A configuration in which the chips adsorbed on the sheet 15 are collected by the separator 31 may be employed.

  Further, the liquid receiving cup 53 is rotated and the bucket 61 installed in the liquid receiving cup 53 is rotated. However, only the bucket 61 may be rotated. Moreover, although the cutting fluid stored in the storage tank 2 was sprayed from the spray nozzle 41 onto the separation plate 32 of the separator 31, a gas other than the cutting fluid, such as liquid or air, was sprayed from the spray nozzle 31 to separate the separator. The chips accumulated on the 31 separation plates 32 can be forced to flow into the bucket 61.

  The cylindrical body 63 of the bucket 61 is configured by punching metal. However, the cylindrical body 63 may be configured by a net-like body such as a wire net, and the mesh of the net-like body may act as the liquid drainage hole 64. .
