TECHNICAL FIELD 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, there has been known a crushing apparatus that cuts a crushing target (processed material) such as cutting chips generated in a large amount from a machine tool such as a cutting machine to reduce the volume. Conventionally, in order to use such a crushing apparatus, a processing means such as a swarf discharged from a machine tool is provided with a conveyor belt provided with a conveyor belt, one end of which is disposed at a processing material discharge port of the machine tool. Thus, the workpiece is dropped to a crushing processing apparatus having an open hopper at the other end of the transfer means, and the crushing processing is performed. Alternatively, a chip storing bucket is arranged at the discharge port of the machine tool, the chip is temporarily stored in the chip storing bucket, and at a timing when the chips are sufficiently accumulated in the bucket, the bucket is taken out and the contents thereof are removed. , Into a crusher located elsewhere.
[0003]
[Problems to be solved by the invention]
However, in the method of temporarily storing the chips in the chip storing bucket, the machine tool must be stopped when the bucket is taken out, resulting in a problem that the working efficiency is deteriorated.
[0004]
On the other hand, in the case of using a conveyor having a conveyor belt, the discharged chips are sequentially conveyed by the conveyor belt, so that the machine tool can be basically operated continuously. . However, the processed material discharged from the machine tool contains a large amount of cutting fluid used during machining together with chips. Due to the viscosity of the cutting fluid, the chips may not fall at the other end of the conveying means while the chips are attached to the conveyor belt, or due to the characteristics of the chips, while the chips are stuck to the conveyor belt. As described above, the chips attached or caught on the conveyor belt often enter the drive unit of the transporting unit, thereby causing an abnormality in the transporting unit. Stopping due to an abnormality in the transport means means that the chips cannot be transported, and as a result, the machine tool is stopped. Therefore, there is a problem that the machine tool may not be able to continuously operate even when using the conveying means provided with the conveyor belt.
In addition, it is necessary to prevent the processed material discharged from the machine tool from scattering inside or around the machine tool and causing a deterioration in the working environment.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a crushing apparatus that enables continuous operation of a machine tool and can maintain a favorable working environment. Further, the present invention provides a crushing apparatus capable of separating a crushing object such as a swarf discharged from a machine tool into a swarf and a cutting fluid and conveying only the swarf to perform a crushing process. The purpose is to:
[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 the input processed material, transport means for transporting the processed material input to the input chamber to the downstream side, and a downstream end of the transport means. And crushing means for crushing the processed material transported by the transporting means, and driving means disposed downstream of the crushing means and rotationally driving the transporting means and the crushing means. This is achieved by a crushing apparatus.
[0007]
According to the present invention, the processed material charged into the charging chamber is transported by the transport means, directly sent to the crushing means, and crushed there. Therefore, transport and crushing can be performed as a series of continuous operations. Thereby, the possibility that the machine tool is stopped due to the temporary stop of the crushing device can be significantly reduced. In addition, since the single driving unit drives the conveying unit and the crushing unit, the crushing apparatus can be downsized. Further, the driving means is arranged further downstream of the conveying means and the crushing means. Due to the miniaturization of such a device and the arrangement of the driving means, it is possible to arrange at least the upstream portion of the crushing processing device in the machine tool, and realize the transport and crushing of the processed material as a series of continuous operations. .
[0008]
In a preferred embodiment, the transporting means includes a shaft provided coaxially with a rotation axis of the crushing means and driven to rotate by the driving means, and a screw blade formed around the shaft.
According to this embodiment, the processed material is conveyed by the screw blade for feeding formed around the same shaft portion as the rotation shaft of the crushing means. Thus, it is possible to prevent chips from adhering to the transporting unit and obstructing continuous driving thereof, as in the case of using a conveyor belt.
[0009]
In a more preferred embodiment, the processing object has a substantially cylindrical cylindrical body including the screw blades, and protrudes radially along a rotation axis on a lower inner wall of the cylindrical body. And a guide plate for guiding the water to the downstream side. According to this embodiment, the processed material rotates as the screw blade rotates in the normal rotation direction, hits the guide plate, and accumulates around the side wall of the guide plate. The accumulated processed material is gradually sent downstream along the guide plate with the rotation of the screw blade due to the twist of the screw blade. By adopting such a configuration, even when the crushing treatment device is arranged horizontally, even when the crushing treatment device is inclined so as to make the downstream side higher, appropriate treatment without stagnation Can be conveyed downstream.
[0010]
In a preferred embodiment, the crushing means includes at least one or more rotary blades protruding radially from the rotation shaft coaxial with the transport means. A single rotary blade may be formed from the rotary 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 radially protrudes from an inner wall of the crushing chamber containing the rotating shaft, and at least one or more fixed blades for crushing the workpiece in cooperation with the rotating blade. Having. For example, it is desirable that the first crushing blade is formed from the lower side of the crushing chamber so as to be continuous with the guide plate of the conveying means or through a small gap. Further, in addition to the first crushing blade, a second crushing blade may be formed at a position facing the first crushing blade, that is, from above the crushing chamber. When the processing object enters the gap between the rotary blade and the crushing blade, the processing object is torn off and becomes a finer state.
[0012]
In the above embodiment, the driving means is disposed adjacent to and downstream of the crushing means. Therefore, a crushing torque is generated near the driving means. Therefore, the driving force of the driving means may be relatively small. In addition, since the load torque used in the transfer means can be smaller than the crushing torque, even if a small drive means is used, the transfer means can be smoothly transferred and crushed without overloading the drive means. Becomes possible.
[0013]
In another preferred embodiment, the input chamber includes a side plate having a plurality of discharge holes for discharging the cutting fluid contained in the input workpiece.
According to this embodiment, most of the cutting fluid contained in the workpiece can be discharged from the charging chamber. This makes it possible to reduce the mass of the processed object transported by the transport unit, and to achieve smoother transport by the transport unit.
[0014]
Further, in another preferred embodiment, the input chamber can be arranged below the discharge section for discharging the processed material inside the machine tool, and the connection between the transfer means and the crushing means protruding from the machine tool. On the lower side in the vicinity of the section, there is provided a support leg erected to support the crushing apparatus. According to this embodiment, the upstream side of the crushing device can be arranged inside the machine tool, and the downstream side can be arranged to protrude from the machine tool. With such an arrangement, the crushed processed material discharged from the crushing means can be stored in the storage bucket disposed below the discharge port of the crushing means. This makes it possible to easily exchange the storage bucket. More preferably, the support legs are height adjustable.
[0015]
In a preferred embodiment, the support leg is arranged so as to be inclined such that the downstream portion is higher than the upstream portion. That is, it is possible to realize the conveyance and crushing of the processed material in substantially the same arrangement and occupied space as the conveyance means provided with the conventional conveyor belt.
Further, it is preferable that a hopper having a shape matching the discharge portion of the processing machine is provided at the upper part of the opening of the input chamber. In addition, it is desirable that the discharge hole of the side plate of the input chamber is arranged so as to be aligned with the collection tank that stores the cutting fluid disposed below the machine tool.
[0016]

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 device 10 according to an embodiment of the present invention, and FIG. 2 is a plan sectional view of the crushing device 10 according to the present embodiment.
As shown in FIGS. 1 and 2, a crushing apparatus 10 according to the present embodiment includes a charging chamber 12, a transfer chamber 14, a crushing unit 16, a processing object transfer unit 18, and a drive unit 20. The charging chamber 12, the transfer chamber 14, and the crushing unit 16 are arranged on the same axis, and the adjacent members are attached and fixed by bolts, respectively. Further, inside the loading chamber 12, the transport chamber 14, and the crushing unit 16, a workpiece transport means 18 coaxial with these members is accommodated, and transports the workpiece loaded into the loading chamber 12 toward the crushing unit 16. .
[0017]
In the present embodiment, the left side in FIG. 1, that is, the side on which the charging chamber 12 is mounted is referred to as an upstream side, and the side on which the driving means 20 is mounted is referred to as a downstream side. The upper side of the charging chamber 12 mounted on the upstream side of the crushing device 10 is opened, and a hopper 13 (shown by a fancy line in FIG. 1) is mounted. In addition, two side plates 30 are attached to the lower part of the input chamber 12 on both sides in a substantially V shape, and a plurality of discharge holes 32 are provided in each side plate 30. By arranging the side plates 30 in a substantially V-shape, the chips fed into the hopper 13 are appropriately conveyed downstream by the processing object conveying means 18 as described later.
[0018]
Further, in the present embodiment, the processed material discharged from the cutting machine or the like is charged into the hopper 13 and falls into the charging chamber 12. Since a large amount of cutting fluid is contained in the processed material, most of the cutting fluid is discharged from the discharge hole 32 of the side plate 30 and only the cutting chips contained in the processed material or the cutting residue slightly remaining The swarf containing the liquid is transported to the downstream side by the workpiece transporting means 18.
The processing object conveying means 18 is composed of a screw 24 and a screw blade 26 provided around the screw 24, and rotates a motor 28 of a driving means 20 mounted on the upstream side of the crushing device 10 in a predetermined direction. By doing so, it is driven to rotate. The upstream end of the processing object transporting means 18 extends to the upstream end of the charging chamber 12 and is rotatably supported by a bearing 15.
[0019]
Further, the processing object transporting means 18 sends the processing material input into the input chamber 12 via the hopper 13 to the transport chamber 14. The processed material fed in is guided by a chip guide plate 22 attached to the lower portion of the transfer chamber 14 along the axial direction so as to protrude toward the center of the axis, and the crushed portion 16 attached to the downstream side is guided. It is transported to the crushing chamber 34. One end of the chip guide plate 22 extends to the upstream end of the charging chamber 12, and the other end extends to the crushing section 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 the “twist” of the screw blade 26. In this way, the processed material is gradually conveyed to the downstream side along the chip guide plate 22. In the present embodiment, in order to convey the processed material to the downstream side along the chip guide plate 22, as described later, even if the crushing processing device 10 is arranged to be inclined such that the downstream side is higher, The processed object can be transported without returning to the upstream side.
[0020]
Further, in the present embodiment, a plurality of projections 25 each having a planar shape protruding in the radial direction of a triangle are formed on a portion of the screw 24 corresponding to the charging chamber 12. As shown in FIG. 6, the projections 25 are arranged at an angular interval of 180 degrees. Further, in a region (see an arrow D in FIG. 1) of the screw 24 from the center of the charging chamber 12 to the downstream end, a notch 27 as shown in FIG. 6 is formed in the screw blade 26.
[0021]
The projections 25 and the cuts 27 are useful for hooking the chips contained in the processing material put into the input chamber 12 to the ends of the projections 25 and the cuts 27 and transporting the chips to the downstream side. is there. In particular, when the chips are easily cut or shredded, or when the chips have few or no protrusions, smoother conveyance can be realized by the protrusions 25 and the cuts 27. However, it goes without saying that the formation of these projections and cuts is optional or optional. Further, the region where the protrusion or the cut is formed is not limited to the above-described embodiment. 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 unit 16 has a crushing chamber 34 provided between the transfer chamber 14 and the driving unit 20. In the present embodiment, the crushing chamber 34 is isolated from the driving means 20 by a labyrinth seal 44 to prevent oil or the like from entering the driving means 20.
[0023]
The crushing chamber 34 has a plate-shaped support frame 35 serving as an upper part thereof, and a cylindrical body 39 serving as a lower part thereof and having a partially opened opening in the axial direction. The cylindrical body 39 is opened at a downstream half portion of the screw 24 in the forward rotation direction (clockwise in FIG. 4), and a discharge port 42 is formed therein. The mounting frame 37 is formed on the upstream side, that is, the wall on the side adjacent to the shaft among the walls forming the discharge port 42. In the crushing chamber 34, a first fixed blade 36 protruding toward the axial center along the axial direction is attached substantially at the center of the lower portion of the support frame 35, while the mounting provided at the lower part of the crushing chamber 34 is provided. A second fixed blade 38 protruding toward the axial 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 a portion corresponding to the crushing chamber 34 at the downstream end portion of the screw 24 of the processing object transporting means 18. 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 with the rotation of the screw 24 when the screw 24 rotates forward (in the direction of arrow “a”, that is, clockwise in FIG. 4).
[0025]
The first fixed blade and the second fixed blade desirably have a certain height between the fixed blade and the rotary blade even when the rotary blade 40 protruding from the screw 24 approaches. With this configuration, in the present embodiment, the processed material transported to the crushing chamber 34 by the chip guide plate 22 and the screw blades 26 of the transport chamber 14 becomes the first fixed blade 36 and the second fixed blade 36. By the blade 38 and the rotary blade 40, they are crushed and crushed finely while tearing. The crushed processed material is discharged from a discharge port 42 provided at a lower portion 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 use state of the crushing device 10 according to the present embodiment. As shown in FIG. 5, the crushing device 10 is arranged such that the opening of the hopper 13 is aligned with the position where the processed material such as chips inside the NC lathe 48 is discharged. The upper portion of the opening of the hopper 13 may be fixed to the processed material discharge port of the NC lathe 48 by a fixing member. The crushing device 10 is attached to the NC lathe 48 at an upstream end thereof by an attaching portion 49 provided at a lower portion of the charging chamber 12.
[0027]
In the present embodiment, the NC lathe 48 is housed in a housing made of a machine frame, and a collection tank 50 for housing a cutting fluid is arranged below the machine frame. The crushing treatment 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 a lower part of the charging chamber 12. Is done. Generally, 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 the collection tank is not provided, an oil pan is provided at the position of the machine frame. Therefore, in any 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 thereof is fixed to a connecting portion between the transfer chamber 14 and the crushing portion 16, and the lower end is supported by the support legs 53 extending to the installation surface. . A caster is provided at the lower end 30 of the support leg 53. Accordingly, the crushing apparatus 10 can be easily moved by releasing the attachment between the upstream side (for example, the upper part of the hopper 13) and the NC lathe 48.
[0029]
In the present embodiment, the crushing treatment device 10 is disposed so as to be inclined such that the downstream portion is higher than the upstream portion. This corresponds to the fact that, from the conventional NC lathe, the chip transferring means provided with the conveyor belt is arranged so as to be gradually higher in the moving direction of the chips by the conveyor belt. That is, the crushing apparatus 10 according to the present embodiment can be arranged 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 at an angle of up to about 45 degrees so as to increase the downstream side in accordance with the position where the processed material 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 disposing the operation panel 52 on the downstream side, it is possible to easily move the crushing apparatus 10 and install a processing machine such as an NC lathe.
[0030]
When using the crushing apparatus 10, the operator presses a start switch of the operation panel 52 to start the motor 28 of the driving means 20. As a result, the screw 24 of the processing object transport means 18 rotates forward. In the present embodiment, the operator selects a desired operation mode of the motor 28 from the automatic operation, the manual operation, and the overload protection operation according to the use state of the crushing apparatus 10 and the crushing state of the processed material. Can be. Thereby, a desired operation state can be realized according to the cutting state of the processed material from the processing machine (for example, the size, hardness, content of the cutting fluid, and the like). The overload protection operation means that the screw 24 is rotated in the reverse direction when the driving means 20 is overloaded in a state where the processed material is sandwiched between the fixed blades 36 and 38 and the rotary blade 40 in the crushing chamber. This means that the processing object is released from the pinched state.
[0031]
Next, the operator starts the operation of the NC lathe 48 to start cutting of the object to be processed. In the present embodiment, since the NC lathe 48 automatically or manually cuts the workpiece for a long time, a large amount of the workpiece is continuously discharged. As shown schematically in FIG. 5, the processed material to be discharged includes cutting chips “p” generated when cutting the processing target object, and a cutting fluid “w” used for preventing heat and the like.
[0032]
The discharged mixture of the swarf “p” and the cutting fluid “w” is charged into the charging chamber 12 from a hopper 13 attached to the upper part of the charging chamber 12. In the present embodiment, it is desirable that the hopper 13 attached to the upper part of the charging chamber 12 has a predetermined shape depending on the attachment state of the crushing device 10, the attachment angle, the scattering state of the processed material, and the like. Thus, even if the processed material is scattered, the hopper 13 can efficiently receive the processed material in a wide range without throwing the inside of the NC lathe 48 into the input chamber 12. .
[0033]
The cutting fluid “w” contained in the input processed material is discharged from the plurality of discharge holes 32 provided in the side plate 30 of the input chamber 12, and is accumulated in the recovery tank 50 provided below the NC lathe 48. You. Chips “p” in the processed material and the remaining cutting fluid that has not been completely discharged from the discharge holes 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 to the downstream side while climbing the inclined transport path.
[0034]
In the present embodiment, the cutting fluid “w” contained in the processing object is discharged from the discharge hole 32 as it is, as described above, and the cutting fluid “p” is processed by the screw 24 of the processing object transport unit 18. In the course of being transported together with the crusher 10, some of the crusher 10 returns to the input chamber 12 toward the upstream side due to the inclination provided in the transport path of the crusher 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 crushed. In addition, foreign matter such as a tip discharge material and a work mixed into the chips is conveyed together with the chips by the screw 24 (the screw blade 26) and the chip guide plate 22, and is discharged from the discharge holes 32 of the transfer chamber. Alternatively, even when a foreign object is caught between the fixed blades 36 and 38 and the rotary blade 40, the screw 24 rotates in the reverse direction by the overload protection operation by the overload protection device, thereby discharging the foreign matter from the discharge hole 32. Can be.
[0036]
In the present embodiment, the screw 24 of the processing object transporting means 18 is rotated by the motor 28 of the driving means 20 attached on the downstream side in a state where the screw blade 26 is retracted. Further, the rotary blade 40 of the crushing unit 16 is rotationally driven at a position adjacent to the driving unit 20, and the screw 24 of the transporting unit 14 is rotated at a separated position. Therefore, the crushing torque can be advantageously generated near the motor 28 (drive source) on the rotating shaft. In addition, since a large load torque is not required for transporting the processing object, no load is applied to the motor 28, and the motor 28 can be operated efficiently.
[0037]
The chips "p" conveyed to the crushing chamber 34 are crushed by the first fixed blade 36, the second fixed blade 38, and the rotating rotary blade 40. More specifically, the chips are pinched between the first fixed blade 36 and the second fixed blade 38 and the rotating rotary blade 40, and are moved from the pinched state, so that the chips are entangled, Or, it will tear off. Thus, the chips are finely crushed in the crushing chamber 34. The crushed chips “p” are 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 a net 58 provided at a lower portion of the chip bucket 54 and is collected at a lower portion 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 therein.
[0038]
As described above, in the present embodiment, chips and the like continuously discharged from a machine tool such as the NC lathe 48 are conveyed, and the chips “p” and the cutting fluid “w” are separated during conveyance, Thus, it is possible to finely crush the cuttings “p”.
[0039]
In the present embodiment, the risk of the crushing device stopping can be significantly reduced as compared with the case where the processing object is transported using a transporting device using a conveyor belt as in the related art. As described above, in the related art, the processed material containing the cutting fluid adheres to the conveyor belt, so that the conveyor belt cannot move, and thus the conveyance unit often stops. On the other hand, according to the present embodiment, there is a possibility that a problem of adherence of a processing object may occur, and it is possible to solve the problem of stopping the apparatus accompanying the problem, whereby the machine tool such as the NC lathe 48 can be used. Long-term continuous operation becomes possible.
