JP 2010-173041 A

  In the apparatus of Patent Document 1, when the amount of chips falling on the carriage reaches a certain amount, the carriage is pulled out from below the impeller. Then, the cart is moved to a disposal place, and the chips accumulated on the cart are discarded. An empty carriage is then placed below the impeller.

  However, when the carriage is moved from the lower side of the chip conveyor to another place, the cutting agent falls from the impeller and the chip conveyor, and the floor surface is soiled.

  An object of the present invention is to effectively capture a cutting agent falling from a chip conveyor, and to prevent the floor surface in a factory from becoming dirty.

  (1) A cutting agent recovery apparatus according to one aspect of the present invention is an apparatus for recovering a cutting agent that is provided in a chip recovery apparatus having a chip conveyor and a carriage for chip recovery and used for cutting. . This apparatus includes a frame and a collection container. The frame is disposed below the discharge end of the chip conveyor. The collection container is supported by the frame, and in conjunction with the movement of the carriage, when the carriage is located at the collection position below the discharge end of the chip conveyor, the collection container is retracted, and the carriage is moved from the collection position. If you do, take a posture. When the collection container is in the retracted posture, the chips and cutting agent discharged from the chip conveyor are collected by the carriage. Further, when the collection container is in the receiving posture, the cutting agent falling from the chip conveyor is collected in the collection container.

  In this apparatus, when the carriage is disposed at the collection position below the discharge end of the chip conveyor, the collection container is in the retracted posture. Therefore, the chips and cutting agent conveyed by the chip conveyor fall into the carriage. When a certain amount of swarf or the like accumulates in the trolley, the trolley is moved to another waste disposal site. At this time, that is, when the carriage is moved from the collection position, the collection container is in the receiving posture and collects the cutting agent falling from the chip conveyor.

  Here, when there is no carriage below the discharge end of the chip conveyor, it is possible to prevent chips and cutting agent from falling on the floor of the factory, and to prevent the floor from becoming dirty.

  (2) In the cutting agent recovery apparatus according to another aspect of the present invention, one end of the recovery container in the direction along the moving direction of the carriage is rotatably supported by the frame. The recovery container is in a retracted posture with one end as a pivot point and the other end facing downward, and the other end of the recovery container in the retracted position is located above or inside the carriage in the recovery position.

  Here, when the recovery container is in the retracted position, the front end of the recovery container faces downward. Therefore, when chips and cutting agents are accumulated in the collection container, the accumulated chips and the like fall downward. Therefore, the collection container is arranged so that the tip when the collection container is in the retracted position is located above or inside the carriage. Therefore, even when the collection container is tilted in the retracted position, the chips and the like are collected in the cart.

  (3) In the cutting agent recovery device according to still another aspect of the present invention, a discharge port is formed in the recovery container. And the tank which accumulates cutting agent and the guide member which guides the cutting agent discharged | emitted from the discharge port of the collection | recovery container to a tank are further provided.

  Here, the cutting agent collected in the collection container is collected in the tank from the discharge port via the guide member. Therefore, it is possible to prevent the cutting agent collected in the collection container from overflowing from the collection container and falling to the floor surface.

  (4) In the cutting agent recovery device according to still another aspect of the present invention, the cutting agent recovery apparatus further includes a link mechanism having a connection portion connected to the recovery container at one end and a contact portion capable of contacting the carriage at the other end. I have. The link mechanism receives and maintains the collection container in a state where the contact portion is not in contact with the carriage. On the other hand, the link mechanism moves the receiving container from the posture to the retracted posture in conjunction with the movement of the carriage when the abutting portion comes into contact with the carriage and the carriage is pushed below the discharge end of the chip conveyor.

  The connecting portion includes a configuration directly connected to the collection container itself and a configuration connected to another member fixed to the collection container.

  Here, when the carriage is pulled from the collection position below the chip conveyor, the collection container is in the receiving position. On the other hand, when the carriage is set at the collection position, the collection container is retracted in conjunction with the movement of the carriage.

  For this reason, the worker can set the collection container in the receiving posture and the retracted posture by simply moving the carriage.

  (5) In the cutting agent recovery device according to still another aspect of the present invention, the link mechanism has a plurality of link members. At least one of the plurality of link members has a variable length so that the angle with respect to the floor surface in the retracted posture and the receiving posture of the collection container can be adjusted.

  Here, the angle of the collection container in the receiving posture can be mainly adjusted by adjusting the length of the link member. For this reason, the fall to the floor surface of a cutting agent can be suppressed more.

  (6) In the cutting agent collection | recovery apparatus which concerns on another side surface of this invention, the chip conveyor has the side wall which protrudes from a conveyance surface in the at least one side of the width direction. And this apparatus is further provided with the air blow and the collection | recovery member. Air blow blows away the cutting agent adhering to the discharge end of the chip conveyor toward the side wall of the chip conveyor. The collecting member collects the cutting agent blown off on the side wall of the chip conveyor.

  Here, the cutting agent adhering to the chip conveyor is blown off toward the side wall of the chip conveyor by air blow, and accumulates on the side wall. And the cutting agent which accumulated on this side wall is collect | recovered by the collection | recovery member, for example to a tank.

  As described above, according to the present invention, it is possible to effectively capture the cutting agent falling from the chip conveyor, and to prevent the floor surface in the factory from becoming dirty.

In FIG. 3, a part of it is omitted. On the left side of FIG. 1, a cutting machine (not shown) such as a lathe is installed.

[Chip collection device 1]
As shown in FIG. 1, the chip collection device 1 includes a chip conveyor 3 and a carriage 4. The chip conveyor 3 conveys the chips generated by the cutting machine. The carriage 4 is disposed at a collection position below the discharge end of the chip conveyor 3 and receives chips that have been conveyed by the chip conveyor 3. When a certain amount of chips accumulates on the cart 4, the chips 4 are moved to another disposal site, and the chips in the cart 4 are discarded. Then, the empty cart 4 is returned to the collection position below the chip conveyor 3.

[Cutting agent recovery device 2]
The cutting agent recovery apparatus 2 includes a frame 10, an oil pan 11 as a recovery container, an air blow 12 (see FIG. 2), and a tank 13 (see FIG. 2). Further, the cutting agent recovery device 2 further includes a link mechanism 15.

<Frame 10>
The frame 10 is disposed at a collection position (position indicated by a two-dot chain line in FIG. 1) below the discharge end of the chip conveyor 3. As shown in FIGS. 1 and 3, the frame 10 includes four vertical frames 18, first to third horizontal frames 19a, 19b, and 19c, and a pair of support frames 20a and 20b. Yes.

  The four vertical frames 18 are installed on the floor surface. The first and second horizontal frames 19a and 19b are arranged to face each other and extend in the conveying direction of the chip conveyor 3 (hereinafter, the cutting machine side in the conveying direction (the left side in FIG. The first and second horizontal frames 19a and 19b are fixed to the upper end surface of the vertical frame 18. The third horizontal frame 19c is the first and second horizontal frame 19a. 19b is fixed so as to connect the end portions on the back side of the first and second horizontal frames 19a and 19b, so that the cart is opened from the front side of the frame 10. 4 can enter the frame 10.

  The pair of support frames 20a and 20b are fixed to the upper surfaces of the first and second horizontal frames 19a and 19b and extend upward. Bearings 22a and 22b are provided at the upper ends of the support frames 20a and 20b.

<Oil pan 11>
The oil pan 11 is formed in a rectangular dish with a shallow depth, and is disposed below the discharge end of the chip conveyor 3, that is, above the carriage 4 at the collection position. As is apparent from FIGS. 2 and 3, a rotating shaft 24 extending in the lateral direction is fixed to the bottom surface of the bottom of the oil pan 11. The rotating shaft 24 is rotatably supported by bearings 22a and 22b provided at the upper ends of the pair of support frames 20a and 20b at both ends.

  With the configuration as described above, the oil pan 11 rotates together with the rotating shaft 24 and can take a receiving posture shown by a solid line in FIG. 1 and a retracting posture shown by a two-dot chain line. When the oil pan 11 is in the receiving posture, it is possible to receive the cutting agent and chips falling from the chip conveyor 3. Further, when the oil pan 11 is in the retracted posture, the cutting agent and the chips falling from the chip conveyor 3 fall into the carriage 4. Further, when the oil pan 11 is in the retracted position, the tip of the oil pan 11 faces downward, and the tip is located inside the cart 4 at the collection position.

  As shown in FIGS. 2 and 3, the oil pan 11 has a discharge port 11 a penetrating downward. A first guide member 26 is fixed to the bottom surface of the bottom of the oil pan 11, more specifically, below the discharge port 11a. The first guide member 26 is made of, for example, an angle material having a substantially L-shaped cross section. Then, the cutting agent dropped from the discharge port 11 a is guided to the tank 13 along the first guide member 26.

<Air blow 12>
As is clear from FIG. 2, the air blow 12 is disposed on one side of the chip conveyor 3. Air is blown from the air blow 12 toward the chip conveyor 3 and toward the other side of the chip conveyor 3. As shown in FIGS. 2 and 4, side walls 3 a that protrude in the vertical direction from the transport surface are formed on both sides of the chip conveyor 3.

  A guide plate 28 is disposed below the side wall 3a on the side where air is blown. The guide plate 28 is arranged such that the tip protrudes further outward (front side) from the discharge end of the chip conveyor 3 and extends to the back side. Further, as shown in FIG. 4, the guide plate 28 is disposed so that the front end is positioned higher than the back side (in FIG. 4, the horizontal plane is indicated by a symbol H). Therefore, the cutting agent dropped from the side wall 3a of the chip conveyor 3 is received by the guide plate 28 and further flows to the back side.

  On the back side of the guide plate 28, a discharge port 28a penetrating downward is formed. Therefore, the cutting agent guided to the back side of the guide plate 28 falls downward through the discharge port 28a. A second guide member 29 is disposed below the guide plate 28. The second guide member 29 extends in a direction orthogonal to the direction in which the guide plate 28 extends. The cutting agent dropped from the discharge port 28 a of the guide plate 28 is guided to the tank 13 by the second guide member 29.

<Link mechanism 15>
As shown in FIGS. 1 and 3, the link mechanism 15 includes first to fourth link members 31, 32, 33, and 34. Each link member 31-34 is formed of a strip-shaped steel plate. One end of the first link member 31 is fixed to the rotating shaft 24, and the rotating shaft 24 rotates by the movement of the first link member 31. The first link member 31 extends to the back side, and the other end of the first link member 31 is rotatably connected to one end of the second link member 32. The other end of the second link member 32 extends downward and is rotatably connected to one end of the third link member 33. The other end of the third link member 33 extends to the near side, and is fixed to one end of the fourth link member 34 so as not to rotate. A connecting portion between the third link member 33 and the fourth link member 34 is rotatably supported on the upper surface of the third horizontal frame 19c. And the 4th link member 34 is extended so that the front-end | tip may hang down below. A bearing 36 is disposed at the tip of the fourth link member 34, and the bearing 36 can come into contact with the side surface of the carriage 4 entering the frame 10.

  The link mechanism 15 is configured so that the weight of the oil pan 11 and the weight of the oil pan 11 are reduced when the cart 4 is not disposed in the frame 10, that is, when the bearing 36 at the tip of the fourth link member 34 is not in contact with the side surface of the cart 4. The oil pan 11 is maintained in the receiving posture by the balance of the weights of the link members 31 to 34.

  Here, of the four link members 31 to 34, for example, the second link member 32 can be changed in length as shown in FIG. Specifically, the 2nd link member 32 is comprised from the strip | belt-shaped 1st member 32a and the 2nd member 32b. And the bolt members 40 and 41 are being fixed toward the mutually opposing edge part of the 1st and 2nd members 32a and 32b. Note that the screw directions of the two bolt members 40 and 41 are reversed. The two bolt members 40 and 41 are screwed into the turnbuckle 42.

  In such a configuration, the distance between the first member 32 a and the second member 32 b can be changed by rotating the turnbuckle 42. That is, the length of the second link member 32 can be changed. By changing the length of the second link member 32, the angle of the receiving posture and the retracting posture of the oil pan 11 (the angle with respect to the horizontal plane) can be finely adjusted.

[Operation]
When cutting with a lathe or the like, as shown in FIG. 6A, the carriage 4 enters the frame 10 and is placed at a collection position below the discharge end of the chip conveyor 3. In this state, the bearing 36 of the fourth link member 34 of the link mechanism 15 is pushed by the side surface of the carriage 4. Therefore, the operation of the link mechanism 15 causes the oil pan 11 to be in a retracted posture so that the tip is directed downward. When the oil pan 11 is in the retracted posture, the tip of the oil pan 11 is located inside the carriage 4.

  In the state shown in FIG. 6A, the chips generated by the cutting process and the cutting agent adhering to the chips are transported by the chip conveyor 3 and fall into the cart 4 below from the discharge end of the chip conveyor 3. Therefore, in this state, the chips and cutting agent are collected inside the carriage 4.

  When a predetermined amount of chips accumulates in the cart 4, it is necessary to discard the chips in the cart 4. In this case, when the cutting process is interrupted, the conveyance of the chip conveyor 3 is stopped. And as shown to FIG. 6B and FIG. 6C, the trolley | bogie 4 is pulled out from the flame | frame 10, and the trolley | bogie 4 is moved to the waste disposal place. At this time, as described above, the oil pan 11 and the link mechanism 15 are configured such that the oil pan 11 is maintained in the receiving posture due to the weight balance. Shifts from the retracted position to the receiving position.

  And if the side surface of the trolley | bogie 4 leaves | separates from the bearing 36 of the 4th link member 34, as shown to FIG. 6D, the oil pan 11 will be in a receiving attitude | position. In this state, the cutting agent and chips falling from the chip conveyor 3 are received by the oil pan 11. Therefore, it is possible to prevent the cutting agent and chips from falling on the floor surface.

  Further, the cutting agent falling on the oil pan 11 falls on the first guide member 26 through the discharge port 11 a of the oil pan 11. Then, the cutting agent is guided to the tank 13 along the first guide member 26 and is collected in the tank 13.

  When the air blower 12 is operated while the chip conveyor 3 is stopped, the cutting agent adhering to the chip conveyor 3 is blown off to the side wall 3 a on one side of the chip conveyor 3 by the air from the air blow 12. The blown-off cutting agent falls down along the side wall 3a, is received by the guide plate 28 below and guided to the back side. And it falls to the 2nd guide member 29 of the downward direction further from the discharge port 28a of the guide plate 28, is guide | induced to the tank 13 along this 2nd guide member 29, and is collect | recovered in the tank 13. FIG.

  When the cart 4 in which the chips are discarded is pushed into the frame 10, the oil pan 11 shifts to the retracted posture by the reverse operation to that described above. That is, the bearing 36 of the fourth link member 34 is pushed by the side surface of the carriage 4, whereby the link mechanism 15 is activated. Then, the rotating shaft 24 to which the oil pan 11 is fixed rotates, and the oil pan 11 assumes a retracted posture in which the tip is located inside the carriage 4.

[Feature]
(1) When the cart 4 is moved from the collection position below the chip conveyor 3, the oil pan 11 is in a receiving posture and receives cutting agent and chips falling from the chip conveyor 3. Therefore, even when the carriage 4 is not in the collection position, it is possible to suppress the floor surface from being soiled by the cutting agent or the like.

  (2) The cutting agent attached to the chip conveyor 3 is blown off by the air blow 12, and the blown-off cutting agent is collected in the tank 13 via the second guide member 29. Accordingly, it is possible to further suppress the contamination of the floor surface due to the dropping of the cutting agent.

  (3) The oil pan 11 assumes a receiving posture and a retracted posture in conjunction with the movement of the carriage 4. Therefore, the operation | work which an operator changes the attitude | position of the oil pan 11 becomes unnecessary.

  (4) When the oil pan 11 is in the retracted position, the tip of the oil pan 11 is located in the cart 4, so that the cutting agent falling from the oil pan 11 in the retracted position can be collected in the cart 4, and the floor surface Stain can be suppressed.

  (5) Since the discharge port 11a is formed in the oil pan 11 and the first guide member 26 that guides the cutting agent from the discharge port 11a to the tank 13 is provided, the amount of cutting agent that falls on the oil pan 11 is large. However, it is possible to prevent the cutting agent from overflowing from the oil pan 11 and falling to the floor surface.

  (6) Since the length of the link member constituting the link mechanism 15 is adjustable, the posture of the oil pan 11 can be finely adjusted. Therefore, the cutting agent can be reliably received by the oil pan 11, and the cutting agent falling from the retracted posture of the oil pan 11 can be reliably collected in the cart 4.
