[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a crushing apparatus for continuously crushing chips generated from a machine tool.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a crushing processing apparatus that cuts and reduces the volume of a crushing object (processed product) such as cutting powder generated from a machine tool such as a cutting machine is known. In order to use such a crushing processing apparatus, conventionally, a processing means such as a chip discharged from a machine tool is transported with a conveyor belt, one end of which is disposed at a processing object discharge port of the machine tool. Thus, the workpiece is transported to the outside of the machine tool, and at the other end of the transporting means, the processed material is dropped into a crushing processing apparatus having an open hopper, and crushing processing is executed. Alternatively, a chip storage bucket is arranged at the discharge port of the machine tool, the chip is once stored in the chip storage bucket, and the bucket is taken out at the timing when the chip is sufficiently accumulated in the bucket, and the contents thereof are removed. , Has been put into a crushing processing device located in another place.
[0003]
[Problems to be solved by the invention]
However, in the method of temporarily storing chips in the chip storage bucket, the machine tool has to be stopped when taking out the bucket, and there is a problem that work efficiency is deteriorated.
[0004]
On the other hand, when using the conveying means provided with the conveyor belt, the discharged chips are sequentially conveyed by the conveyor belt, so that basically the machine tool can be operated continuously. . However, the processed material discharged from the machine tool contains a large amount of cutting fluid used during machining with the chips. Due to the viscosity of the cutting fluid, there is a case where the chips do not fall at the other end of the conveying means while the chips adhere to the conveyor belt, or due to the characteristics of the chips, the chips are stuck on the conveyor belt. Thus, it has often occurred that the chips adhering to or caught on the conveyor belt enter the drive unit of the conveying unit, thereby causing an abnormality in the conveying unit. Stopping due to an abnormality in the conveying means means that the chips cannot be conveyed, and as a result, the machine tool is stopped. Therefore, there is a problem that the machine tool cannot be continuously operated even when the conveying means including the conveyor belt is used.
In addition, it is necessary to prevent the processed material discharged from the machine tool from being scattered inside and around the machine tool and deteriorating the working environment.
[0005]
An object of this invention is to provide the crushing processing apparatus which enables continuous operation of a machine tool and can maintain a favorable working environment. Moreover, this invention provides the crushing processing apparatus which sorts the crushing objects, such as the chip discharged | emitted from a machine tool, into a chip and a cutting fluid, and can convey only a chip and crush it. For the purpose.
[0006]
[Means for Solving the Problems]
An object of the present invention is to provide an input chamber that is disposed on the upstream side and receives an input processed product, a transfer unit that transfers the processed product input to the input chamber to the downstream side, and a downstream end of the transfer unit And crushing means for crushing the processed material conveyed by the conveying means, and a driving means arranged on the downstream side of the crushing means and for rotationally driving the conveying means and the crushing means. This is achieved by the crushing processing apparatus.
[0007]
According to the present invention, the processed material put into the charging chamber is transported by the transporting means, sent directly to the crushing means, and crushed there. Therefore, conveyance and crushing can be performed as a series of continuous operations. Thereby, the possibility that the machine tool may stop due to the temporary stop of the crushing apparatus can be significantly reduced. In addition, since the single driving means drives the conveying means and the crushing means, the crushing apparatus can be reduced in size. Further, the driving means is arranged further downstream of the conveying means and the crushing means. By such downsizing of the apparatus and arrangement of the driving means, it becomes possible to arrange at least the upstream part of the crushing processing apparatus in the machine tool, and realize conveyance and crushing of the processed material as a series of continuous operations. .
[0008]
In a preferred embodiment, the transport means includes a shaft portion that is provided coaxially with the rotation shaft of the crushing means and is rotationally driven by the drive means, and screw blades formed around the shaft portion.
According to this embodiment, the processed material is conveyed by the screw blade for feeding formed around the same shaft portion as the rotating shaft of the crushing means. As a result, it is possible to prevent chips from adhering to the conveying means and hindering continuous driving as in the case of using a conveyor belt.
[0009]
In a more preferred embodiment, the processing means has a substantially cylindrical cylindrical body including the screw blades, and protrudes radially on the lower inner wall of the cylindrical body along the rotation axis. Has a guide plate for guiding the gas to the downstream side. According to this embodiment, the processed material rotates as the screw blade rotates in the forward rotation direction, hits the guide plate, and accumulates around the side wall of the guide plate. The collected processed products are gradually fed downstream along the guide plate as the screw blades rotate due to the twisting of the screw blades. By adopting such a configuration, even if the crushing treatment apparatus is horizontally arranged, or even if it is arranged to be inclined so as to make the downstream side higher, it is possible to appropriately handle the processed material without stagnation. Then, it can be conveyed downstream.
[0010]
In a preferred embodiment, the crushing means includes at least one rotary blade that protrudes in the radial direction from the rotary shaft that is coaxial with the conveying means. A single rotary blade may be formed from the rotating shaft of the crushing means, or two rotary blades may be formed at an angular interval of 180 °.
[0011]
In a more preferred embodiment, the crushing means protrudes radially from the inner wall of the crushing chamber including the rotation shaft, and cooperates with the rotary blade to crush the processed material. Have For example, it is desirable that the first crushing blade is formed from the lower side of the crushing chamber so as to continue from the guide plate of the conveying means or through a slight gap. Furthermore, in addition to the first crushing blade, a second crushing blade may be formed from a position facing the first crushing blade, that is, from above the crushing chamber. When the processed material enters the gap between the rotary blade and the crushing blade, the processed material is torn off and becomes finer.
[0012]
In the above embodiment, the driving means is disposed adjacent to the crushing means and downstream thereof. Therefore, the crushing torque is generated in the vicinity of the driving means. Therefore, the driving force of the driving means may be relatively small. In addition, since the load torque used in the conveying means may be smaller than the crushing torque, even when a small driving means is used, smooth conveyance and crushing can be realized without overloading the driving means. Is possible.
[0013]
In another preferred embodiment, the input chamber is provided with a side plate having a plurality of discharge holes for discharging the cutting fluid contained in the charged processed material.
According to this embodiment, most of the cutting fluid contained in the processed material can be discharged in the charging chamber. Thereby, the mass of the processed material conveyed by a conveyance means can be reduced, and conveyance by a smoother conveyance means can be implement | achieved.
[0014]
Furthermore, in another preferred embodiment, the input chamber can be arranged below the discharge portion for discharging the processed material inside the machine tool, and is connected to the conveying means and the crushing means protruding from the machine tool. On the lower side of the vicinity of the section, a support leg erected to support the crushing treatment apparatus is provided. According to this embodiment, the upstream side of the crushing apparatus can be disposed inside the machine tool, and the downstream side can be disposed so as to protrude from the machine tool. With such an arrangement, the crushed processed product discharged from the crushing means can be accommodated in the accommodation bucket arranged at the lower part of the discharge port of the crushing means. As a result, the storage bucket can be easily replaced. More preferably, the height of the support leg is adjustable.
[0015]
In a preferred embodiment, the support leg is inclined so that the downstream portion is higher than the upstream portion. In other words, it is possible to realize the conveyance and crushing of the processed object with substantially the same arrangement and occupied space as the conveying means including the conventional conveyor belt.
Further, it is desirable that a hopper having a shape matching the discharge portion of the processing machine is provided in the upper portion of the input chamber that is open. Further, it is desirable that the discharge hole of the side plate of the input chamber is disposed so as to be aligned with the recovery tank that stores the cutting fluid disposed at the lower part of the machine tool.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front sectional view of a crushing treatment apparatus 10 according to an embodiment of the present invention, and FIG. 2 is a plan side sectional view of the crushing treatment apparatus 10 according to the present embodiment.
As shown in FIGS. 1 and 2, the crushing processing apparatus 10 according to the present embodiment includes an input chamber 12, a transfer chamber 14, a crushing unit 16, a processed material transfer means 18, and a drive means 20. The input chamber 12, the transfer chamber 14, and the crushing portion 16 are arranged on the same axis, and the adjacent members are respectively attached and fixed with bolts. In addition, in the charging chamber 12, the transfer chamber 14, and the crushing section 16, a processed material transfer means 18 that is coaxial with these members is housed, and the processed material charged in the charging chamber 12 is transferred toward the crushing section 16. .
[0017]
In the present embodiment, the left side in FIG. 1, that is, the side to which the input chamber 12 is attached is referred to as the upstream side, and the side to which the driving means 20 is attached is referred to as the downstream side. An upper side of the input chamber 12 attached to the upstream side of the crushing processing apparatus 10 is opened, and a hopper 13 (shown by an imaginary line in FIG. 1) is attached. In addition, two side plates 30 are attached to both sides of the lower portion of the input chamber 12 in a substantially V shape, and each side plate 30 is provided with a plurality of discharge holes 32. By arranging the side plate 30 in a substantially V shape, the chips put into the hopper 13 are appropriately conveyed downstream by the processed material conveying means 18 as will be described later.
[0018]
In the present embodiment, the processed product discharged from the cutting machine or the like is put into the hopper 13 and falls into the loading chamber 12. Since a large amount of cutting fluid is contained in the processed material that has been input, most of the cutting fluid is discharged from the discharge holes 32 of the side plate 30, and only the cuttings contained in the processed material or some remaining cutting fluid is left. Chip containing the liquid is conveyed downstream by the processed material conveying means 18.
The workpiece conveying means 18 includes a screw 24 and screw blades 26 provided around the screw 24, and rotates a motor 28 of a driving means 20 attached to the upstream side of the crushing processing apparatus 10 in a predetermined direction. It is driven to rotate. The upstream end portion of the processed material conveying means 18 extends to the upstream end portion of the charging chamber 12 and is rotatably supported by the bearing 15.
[0019]
Further, the processed material transport means 18 sends the processed material charged into the input chamber 12 through the hopper 13 into the transport chamber 14. The processed material that has been fed is guided by a chip guide plate 22 that is attached to the lower part of the transfer chamber 14 in the axial direction so as to protrude toward the center of the shaft. It is conveyed to the crushing chamber 34. The chip guide plate 22 has one end extending to the upstream end of the charging chamber 12 and the other end extending to the crushing portion 16. In the present embodiment, as the screw blade 26 rotates in the forward rotation direction (clockwise), the processed material rotates in the forward rotation direction, hits the chip guide plate 22, and the side wall of the chip guide plate 22. Accumulate around. The processed material accumulated around the side wall of the chip guide plate 22 is gradually sent to the downstream side by “twisting” of the screw blades 26. In this way, the processed material is gradually conveyed downstream along the chip guide plate 22. In the present embodiment, in order to convey the processed material downstream along the chip guide plate 22, as will be described later, the crushing treatment device 10 may be disposed so as to be inclined so that the downstream side becomes higher, The processed material can be transported without returning to the upstream side.
[0020]
Further, in the present embodiment, a plurality of projecting portions 25 each having a planar shape projecting in the radial direction of a triangle are formed in a portion corresponding to the input chamber 12 of the screw 24. As shown in FIG. 6, the protrusions 25 are arranged at an angular interval of 180 degrees. Further, in the region of the screw 24 extending from the center portion of the charging chamber 12 to the downstream end portion (see arrow D in FIG. 1), a cut 27 as shown in FIG.
[0021]
The protrusions 25 and the cuts 27 are useful for catching the chips contained in the processed material put into the charging chamber 12 and transporting the chips downstream of the protrusions 25 and the cuts 27. is there. In particular, when the chips are easily cut or broken, or when there are few or no protrusions on the chips, smoother conveyance can be realized by the protrusions 25 and the cuts 27. However, it goes without saying that the formation of these protrusions and cuts is optional or optional. Further, the region where the protrusion or the cut is formed is not limited to the above embodiment, and for example, the cut of the screw blade may be formed over the entire region corresponding to the charging chamber.
[0022]
As shown in detail in FIGS. 3 and 4, the crushing section 16 has a crushing chamber 34 provided between the transfer chamber 14 and the driving means 20. In the present embodiment, the crushing chamber 34 is isolated from the driving means 20 by the labyrinth seal 44 to prevent oil or the like from entering the driving means 20.
[0023]
The crushing chamber 34 has a plate-like support frame 35 that forms an upper portion thereof, and a cylindrical body 39 that forms a lower portion thereof and is partially opened in the axial direction. The cylindrical body 39 opens at the downstream half of the forward rotation direction of the screw 24 (clockwise in FIG. 4), and a discharge port 42 is formed there. A mounting frame 37 is formed on the upstream side of the wall forming the discharge port 42, that is, the wall adjacent to the shaft. In the crushing chamber 34, a first fixed blade 36 protruding toward the axial center along the axial direction is attached to a substantially lower center of the support frame 35, and on the other hand, an attachment provided at a lower portion of the crushing chamber 34. A second fixed blade 38 protruding toward the axis center is attached to the frame 37 along the axial direction.
[0024]
Further, two rotary blades 40 that protrude radially outward along the axis are attached to the screw 24 of the workpiece conveying means 18 at a portion corresponding to the crushing chamber 34 at the downstream end thereof. In the present embodiment, the two rotary blades 40 are arranged at an angular interval of 180 °. The rotary blade 40 is configured to rotate along with the rotation of the screw 24 when the screw 24 rotates in the forward direction (in the direction of the arrow “a”, that is, clockwise in FIG. 4).
[0025]
In the first fixed blade and the second fixed blade, it is desirable that the clearance through which the processed material passes between the fixed blade and the rotary blade is high to some extent even when the rotary blade 40 protruding from the screw 24 is close. By adopting such a configuration, in the present embodiment, the processed material conveyed to the crushing chamber 34 by the chip guide plate 22 and the screw blades 26 in the conveyance chamber 14 is the first fixed blade 36 and the second fixed blade. The blade 38 and the rotary blade 40 are crushed finely while tangling and tearing. The crushed processed product is discharged from a discharge port 42 provided in the lower part of the crushing chamber 34.
[0026]
An application example of the crushing apparatus 10 configured as described above will be described below. FIG. 5 is a diagram illustrating an example of a usage state of the crushing apparatus 10 according to the present embodiment. As shown in FIG. 5, the crushing processing apparatus 10 is arranged so that the opening of the hopper 13 is aligned with a position where a processed material such as chips inside the NC lathe 48 is discharged. The upper opening portion of the hopper 13 may be fixed to the processed material discharge port of the NC lathe 48 with a fixing member. The crushing treatment apparatus 10 is attached to the NC lathe 48 by an attachment portion 49 provided at the lower end of the input chamber 12 at the upstream end thereof.
[0027]
In the present embodiment, the NC lathe 48 is accommodated in a housing made of a machine frame, and a recovery tank 50 for accommodating cutting fluid is disposed below the machine frame. The crushing processing apparatus 10 is fixed to a machine frame disposed below the NC lathe 48 and above the recovery tank 50 by a fixing means such as a screw by a mounting portion 49 provided at the lower portion of the input chamber 12. Is done. In general, in a machine tool such as an NC lathe, a recovery tank 50 for recovering a cutting fluid is disposed at a lower portion, and a machine frame is formed at an upper portion thereof. When no collection tank is arranged, an oil pan is arranged at the position of the machine frame. Therefore, in either case, one end of the crushing apparatus according to the present embodiment can be fixed at a predetermined position in the NC lathe.
[0028]
Further, on the downstream side of the crushing device 10, the upper end is fixed to the connecting portion between the transfer chamber 14 and the crushing unit 16, and the lower end is supported by the support leg 53 extending to the installation surface. . A caster is provided at the lower end 30 of the support leg 53. Therefore, the crushing apparatus 10 can be easily moved by releasing the attachment of the upstream side (for example, the upper part of the hopper 13) and the NC lathe 48.
[0029]
In this Embodiment, the crushing processing apparatus 10 is inclined and arrange | positioned so that a downstream part may be located higher than an upstream part. This corresponds to the fact that, from the conventional NC lathe, the chip transfer means provided with the conveyor belt is arranged so as to gradually increase in the moving direction of the chip by the conveyor belt. That is, it becomes possible to arrange the crushing apparatus 10 according to the present embodiment in place of the chip conveying means provided with the conventional conveyor belt. The crushing processing apparatus 10 according to the present embodiment can be arranged to be inclined so as to raise the downstream side up to about 45 degrees in accordance with the position at which the processed product is discharged from the machine tool to be installed. . The operation panel 52 may be attached to a predetermined position on the downstream side, for example, above the support frame 53. Thus, by arranging the operation panel 52 on the downstream side, it is possible to facilitate the movement of the crushing processing apparatus 10 and the installation of a processing machine such as an NC lathe.
[0030]
When using the crushing apparatus 10, the operator presses the start switch of the operation panel 52 to activate the motor 28 of the driving means 20. As a result, the screw 24 of the workpiece conveying means 18 rotates forward. In the present embodiment, the operator selects a desired operation mode of the motor 28 from automatic operation, manual operation, and overload protection operation according to the usage state of the crushing processing apparatus 10 and the crushing state of the processed material. Can do. Thereby, a desired driving | running state is realizable according to the cutting state (For example, the magnitude | size of chip, hardness, the content of cutting fluid, etc.) of the processed material from a processing machine. In the overload protection operation, the screw 24 is rotated in the reverse direction when the drive means 20 is overloaded with the processed material sandwiched between the fixed blades 36 and 38 and the rotary blade 40 in the crushing chamber. This means that the processed product is released from the sandwiched state.
[0031]
Next, the operator starts the operation of the NC lathe 48 and starts cutting the workpiece. In the present embodiment, the NC lathe 48 automatically or manually cuts the workpiece for a long time, so that a large amount of processed material is continuously discharged. As schematically shown in FIG. 5, the discharged processed material includes a chip “p” that is produced when a workpiece is cut and a cutting fluid “w” that is used to prevent heating.
[0032]
The mixture of the discharged chip “p” and the cutting fluid “w” is charged into the charging chamber 12 from a hopper 13 attached to the upper portion of the charging chamber 12. In the present embodiment, it is desirable that the hopper 13 attached to the upper portion of the input chamber 12 has a predetermined shape depending on the attachment state of the crushing treatment apparatus 10, the attachment angle, the scattered state of the processed material, and the like. As a result, even if the processed material is scattered, the NC lathe 48 is not contaminated, and the processed material in a wide range can be efficiently received by the hopper 13 and input into the input chamber 12. .
[0033]
The cutting fluid “w” included in the charged processed material is discharged from a plurality of discharge holes 32 provided in the side plate 30 of the charging chamber 12 and accumulated in a recovery tank 50 provided below the NC lathe 48. The Further, the chip “p” in the processed material and the remaining cutting fluid that has not been completely discharged from the discharge hole 32 are removed by the screw blades 26 provided around the screw 24 of the processed material conveying means 18. While being guided by the guide plate 22, it is transported downstream while going up the inclined transport path.
[0034]
In the present embodiment, the cutting fluid “w” contained in the processed material is not only discharged from the discharge hole 32 as described above, but also the chip “p” by the screw 24 of the processed material conveying means 18 as described above. In the middle of being conveyed, there is also a thing which returns to the input chamber 12 toward the upstream side due to the inclination provided in the conveying path of the crushing processing apparatus 10 and is discharged from the discharge hole 32.
[0035]
The chips “p” conveyed to the downstream side are conveyed to the crushing chamber 34 of the crushing unit 16 and are crushed. In addition, foreign matter such as tip waste material and workpiece mixed in the chips is also conveyed together with the chips by the screw 24 (screw blade 26) and the chip guide plate 22, and is discharged from the discharge hole 32 of the transfer chamber. Alternatively, even when a foreign object is sandwiched between the fixed blades 36 and 38 and the rotary blade 40, the screw 24 is reversely rotated by the overload protection operation by the overload protection device, and is thereby discharged from the discharge hole 32. Can do.
[0036]
In the present embodiment, the screw 24 of the workpiece conveying means 18 is rotated by the motor 28 of the driving means 20 attached downstream so that the screw blades 26 are drawn. Moreover, the rotary blade 40 of the crushing part 16 is rotationally driven at a position adjacent to the driving means 20, and the screw 24 of the conveying means 14 is rotated at a separated position. Therefore, the crushing torque can be generated in the vicinity of the motor 28 (drive source) on the rotating shaft, which is advantageous. In addition, since a large load torque is not required when conveying the processed material, the motor 28 is not loaded and can be operated efficiently.
[0037]
The chip “p” conveyed to the crushing chamber 34 is crushed by the first fixed blade 36, the second fixed blade 38 and the rotating rotary blade 40. More specifically, the chips are sandwiched between the first fixed blade 36 and the second fixed blade 38 and the rotating rotary blade 40, and the chips are entangled by being moved from the sandwiched state, Or it will tear off. In this way, the chips are finely crushed in the crushing chamber 34. The crushed chip “p” is discharged from the discharge port 42 and stored in the chip bucket 54. Further, the cutting fluid “w” slightly contained in the chip “p” passes through the net 58 provided in the lower part of the chip bucket 54 and is collected in the lower part of the chip bucket 54. The collected cutting fluid “w” is sucked up by the pump 56, sent to the collection tank 50, and stored.
[0038]
As described above, in the present embodiment, the chips and the like continuously discharged from the machine tool such as the NC lathe 48 are conveyed, and the chips “p” and the cutting fluid “w” are separated during the conveyance, and finally In particular, the chip “p” can be finely crushed.
[0039]
Compared with the case where a processed material is conveyed using a conveying means using a conveyor belt as in the prior art, in the present embodiment, the possibility that the crushing processing apparatus stops can be significantly reduced. As described above, conventionally, the processed material containing the cutting fluid adheres to the conveyor belt, so that the conveyor belt cannot move, and thus the conveying means often stops. On the other hand, according to the present embodiment, there is a possibility that the problem of adhesion of the processed material may occur, and the problem of the stoppage of the apparatus accompanying this may be solved. It is possible to operate continuously for a long time.
[0040]
The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
For example, in the above-described embodiment, the crushing apparatus 10 is installed in a machine tool that performs continuous automatic operation for a long time, such as an NC (numerical control) lathe 48, but is not limited thereto. For example, you may install and use on machine tools, such as a normal lathe, a profile lathe, and an automatic lathe.
[0041]
Moreover, in the said embodiment, although the crushing processing apparatus 10 has arrange | positioned the chip bucket 54 for chip collection near machine tools, such as NC (numerical control) lathe 48, it is not limited to this. . For example, it may be arranged at a desired position by adjusting the lengths of the transfer chamber 14 and the screw 24.
Furthermore, in the said embodiment, although the processed material is crushed by two rotary blades and two fixed blades, it is not limited to this, and one or three or more rotary blades are fixed. A blade may be used.
In the present specification, the function of one means may be realized by two or more physical means, or the function of two or more means may be realized by one physical means.
[0042]
【The invention's effect】
According to the present invention, by arranging the driving means such as a motor downstream, it is possible to generate a crushing torque near the driving means, thereby reducing the load on the driving means. Further, according to the present invention, the chips and cutting fluid can be discharged continuously, and these can be collected separately.
[0043]
In other words, according to the present invention, it is possible to provide a crushing processing apparatus that enables continuous operation of a machine tool and maintains a good working environment, and to crush objects such as chips discharged from the machine tool. Objects can be separated into chips and cutting fluid, and only the chips can be conveyed and crushed.
