PART CONVEYANCE DEVICE AND MACHINE TOOL WITH THE CONVEYANCE DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component takeout device which is installed in a machine tool and grips a machined part from a work to be taken out of the machine, and a machine tool provided with the takeout device.

In general, for example, Japanese Laid-Open Patent Publication No. 2001-310201 discloses an automatic lathe in which a plurality of parts are continuously processed using a long bar as a work, or a plurality of parts are continuously processed by automatically supplying a short bar as a work. As shown, there exists a movable type chute which receives the above-mentioned component separated from the main shaft, and the receiving box which accommodates the components which moved on this separate chute is provided.

The automatic lathe is stacked by receiving the parts in the receiving box via the separate chute. In addition, the automatic lathe which falls on the belt conveyor provided in the inside of an automatic shelf (inside of a cover structure) instead of receiving a component, and discharges it from the preformed conveyor hole to the outside is also known.

Some of the above-mentioned parts must be treated with particular care after processing such as extremely thin and easily deformable diameters, high dimensional accuracy, or small surface roughness due to mirror finish. Such parts are generally held by a chuck or a hand, not by a separate suit or the like, so as not to be subjected to an impact. The gripped part is conveyed onto the belt conveyor by moving the arm structure with the chuck or hand at the tip in the direction intersecting the axis of the main shaft. However, since the arm structure is generally relatively large, when moving the arm structure in the direction intersecting with the axis center of the main axis, the arm structure is in the inner side than the outer near position of the mount end edge on the moving direction side. It is difficult to accommodate inside. If the arm structure protrudes outward from the position near the outer side of the edge of the mount end in the moving direction, there is a problem that the installation area of the automatic lathe becomes large.

In particular, machine tools such as automatic lathes are often used in combination with facilities such as palletizers that receive parts from machine tools. In this case, the palletizer is often disposed adjacent to the front surface (operation side) of the machine tool from the viewpoint of layout restrictions and workability. It is not desirable to protrude the above-mentioned arm structure outwardly to the outside of the mount end edge on the front side of the machine tool.

The present invention is a structure in which the workpiece mounted on the main shaft is compactly accommodated without being extremely protruding outward from the outside of the mount end edge of the machine tool for processing into a predetermined part, and the machined part from the workpiece is smoothly taken out to the outside of the machine tool. It is an object of the present invention to provide a component taking out device and a machine tool provided with the carrying out device.

The movement direction of the said 1st conveyance means can be made into the horizontal direction of the said main shaft.

More specifically, the transverse direction of the main axis is a direction obliquely downward or obliquely upward from the main axis.

The component dispensing apparatus is provided with the hand which the said 1st conveying means hold | grips the said component, and the linear motion member which supports this hand so that rotation is possible by one point, and this linear motion member carries out the moving direction of a hand. Therefore, a linear guide for moving in the lateral direction is provided, a guide groove for installing the posture changing means between the fixed side and the hand side for the movement of the linear member, and an operation installed on the guide side and engaging with the guide groove. A first groove parallel to the movement direction of the linear motion member in the guide groove so as to change a posture between the horizontal direction and the vertical direction according to the movement of the linear motion member by the linear motion guide. It is possible to provide a second groove continuously formed to intersect one groove.

The second conveying means has a part receiving part on which a part held by the first conveying means is mounted and a base supporting the part receiving part at a position to receive a part from the first conveying means. It is possible to comprise reciprocally between the position which receives the said part, and the carrying out position of a part.

The automatic lathe 1 is equipped with the mount 5, the back spindle base 4 provided in the center upper part of the mount 5, and a tool stand (not shown). The back spindle 41 is mounted on the back spindle stand 4 so as to face the spindle 4 '. The workpiece (the rod in the illustrated example) is detachably attached to the front end of the rear spindle 41. In addition to the machining of the workpiece in the main shaft 4 ', the automatic lathe 1 has a rear main shaft 41 by a tool mounted on a tool post (not shown) by the slide movement in the axial center direction of the rear main shaft 41. In (), the workpiece is processed to process a component having a predetermined shape.

The automatic lathe 1 has a cover structure 6 configured to cover the entire upper half of the automatic lathe 1 including the mount 5 and the area near the outer side of the mount end edge. The cover structure 6 prevents scattering of cutting powder and grinding oil during processing of the workpiece on the main shaft and the back spindle. The cover structure 6 restricts the operator's access to the inside of the automatic lathe (particularly the machining area). The area near the outer edge of the mount end edge means an area within a range that extends outward to a certain extent from the region extending in the vertical end direction and does not substantially affect the operator's operation or the installation layout of the machine tool.

The said automatic lathe 1 is provided with the component carrying-out apparatus 10 which carries out the component 2 processed from the workpiece | work to the outside from the back spindle 41. As shown in FIG. 3, the carrying out apparatus 10 is a component 2 from the component separator 12 and the component separator 12 which hold | maintain the above-mentioned component 2 attached to the back spindle 41 after completion | finish of processing. It is comprised by the conveyance shuttle 14 which receives this. As shown in FIG. 2A, channel portions 8 and 8 'extending in the horizontal direction are formed before and after the mount 5. The channel portion 8 is located below the rear spindle mount 4. The cover structure 6 blocks the top of the channel portions 8, 8 ′. The cover structure 6 blocks the upper portion of the channel portions 8 and 8 ', thereby forming a laterally facing yaw-shaped portion near the boundary between the cover structure 6 and the mount 5. . The conveyance shuttle 14 is provided in the channel part 8 of the front side which is the side where the palletizer 3 was arrange | positioned, and is arrange | positioned in the front yaw-shaped part. The conveyance shuttle 14 is located below the rear main shaft 41 and the component separator 12. The component separator 12 is provided between the back spindle 41 and the conveyance shuttle 14. The cover structure 6 covers the processing chamber with a portion blocking the upper portions of the channel portions 8, 8 ′. The cover structure 6 is provided with the perpendicular surface which covers the opening part of a concave-shaped part in the same surface as the front side cross section of the mount 5. By the structure of the said cover structure, since the concave-shaped part is shielded from the inside of a cover structure, scattering of cutting pieces etc. during workpiece | work processing to the conveyance shuttle 14 is prevented. The palletizer 3 is disposed adjacent to the vertical surface of the cover structure 6 so as to be located on the front operation surface 7 side of the automatic lathe 1 for improving workability.

The component separator 12 is equipped with the holding unit which is the 1st conveying means which hold | grips the component 2 and is carried out from the back spindle 41. The gripping unit supports the hand 16 gripping the component 2, the hand support member 18 for holding and supporting the hand 16, and the hand support member 18 so as to be pivotable by the point 20. Made of a linear member 22. As shown in FIG. 3, the hand 16 is provided with the opposing claw, and can hold and grip the outer peripheral side of the component 2 by opening and closing of a claw. It is also possible to use a chuck instead of the hand 16 as the gripping means for gripping the component 2. The component separator 12 is provided with the linear guide 24 which slides the linear motion member 22 freely. The linear guide 24 has a supporting plate 30 and a rodless cylinder 32. The support plate 30 is fixed by the bolt 28 to the installation block 26 fixed to the mount 5 in the state which inclined diagonally downward from the back main shaft toward the conveyance shuttle 14. By the support plate 30 being fixed to the mount 5, the component separator 12 is arrange | positioned above the conveyance shuttle 14, and is fixed. The rodless cylinder 32 is disposed obliquely downward along the support plate 30.

The rodless cylinder 32 has a guide shaft 34 and a rodless cylinder moving body 38. The guide shaft 34 is disposed on the back surface of the support plate 30. The moving body 38 protrudes forward than the opening part 40 provided in the support plate 30. The moving body 38 moves along the guide shaft 34 by the drive of the rodless cylinder 32.

The support plate 30 is fixed with a linear guide 42 extending in parallel with the guide shaft 34. The linear motion member 22 is integrally attached to the movable body 38 by the bolt 36. The linear motion member 22 is supported by the linear motion guide 42 with the linear motion guide moving body 44 interposed therebetween. The linear motion member 22 is guided by the linear motion guide 42 by the drive of the rodless cylinder 32, and moves along the guide shaft 34 obliquely downward with the moving body 38 integrally. The holding unit moves by the movement of the linear member 22.

The hand support member 18 has an actuation shaft 46. The operation shaft guide 48 is fixed to the support plate 30 which is fixed to the movement of the linear member 22. The guide shaft 50 is formed in the operating shaft guide 48. The working shaft 46 is slidably engaged with the guide groove 50. The guide groove 50 is L-shaped in which R of predetermined diameter was formed in the corner part. One L-shaped side of the guide groove 50 forms a first groove 50a parallel to the guide axial direction G of the rodless cylinder 32. The other L-shaped side of the guide groove 50 forms a second groove 50b extending upwardly perpendicular to the guide direction G. As shown in FIG. The first groove 50a and the second groove 50b cross each other and are continuously formed.

As shown in Fig. 4A, the component separator 12 is a component in which the hand 16, which is waiting in the yaw-shaped portion 8, is finished on the rear spindle 41 and the machining at the position Al is completed. In order to grip 2), it moves in the state which protruded toward the back main shaft 41. FIG. When the hand 16 grips the component 2, the working shaft 46 of the hand support member 18 is located at position B1. The component 2 is transferred from the rear spindle 41 to the hand 16 by the rear spindle 41 releasing and retracting the grip of the component 2 from the state in which the hand 16 grips the component 2. . Subsequently, by the drive of the rodless cylinder 32, the holding unit moves away from the rear main shaft 41 sideways obliquely downward along the guide direction G of the linear guide 24 (lower left in the illustrated example). Go to. When the operating shaft 46 moves to the position B2 just in front of the corner portion of the guide groove 50, the component 2 gripped by the hand 16 moves to the position A2.

The operating shaft 46 continues to move along the guide groove 50. However, since the guide groove 50 is L-shaped as described above, the moving direction of the operating shaft 46 gradually changes in the vertical direction from the direction G to the direction G upward. On the other hand, the point 20 of the hand support member 18 continues to move linearly along the direction G integrally with the linear member 22. Accordingly, in accordance with the change in the moving direction of the operating shaft 46, the hand support member 18 is shown in FIG. 4A with respect to the linear member 22 about the point 20 (shown as "+" in FIG. 4A). Turn clockwise. The hand 16 is inclined by the rotation of the hand support member 18. For example, when the operating shaft 46 is at position B3, the part 2 gripped by the inclined hand 16 is at position A3.

If the operating shaft 46 continues to move from position B3 to position B4 and position B5, the hand support member 18 further turns to tilt the hand 16 and the component 2 moves to position A4 and position A5. . Therefore, the component 2 moves linearly from the position Al to the position A2, and moves along the curve which is convex downward from the position A2 to the position A2, as shown by the trace T. FIG. When the component 2 is positioned at the last position A5, the hand 16 is changed in posture in a vertical posture which is approximately vertically downward (see FIG. 7).

When the hand 16 is in a vertical position, the component 2 is supported at an upper position in the yaw-shaped portion 8 so that the shaft core is parallel to the shaft core of the rear main shaft 41. When the hand 16 constituting a part of the gripping unit is changed in posture in the vertical position, even if the gripping unit moves to the yaw shape 8 side, the gripping unit moves to the outside of the yaw shape 8. It does not protrude and is accommodated inside the front edge of the mount 5. In this embodiment, the attitude | position change means which changes the attitude | position of the hand 16 has the simple and easy structure which consists of the operating shaft 46, the guide groove 50, etc.

As shown in FIG. 2B and FIG. 4B, by holding the support plate 30 'to the mount 5 in an inclined state obliquely upward, it is also possible to set it as the structure which the holding unit obliquely moves upward from the back main shaft. In addition, except that the component separator 12 'is inclined upwardly, the configuration of FIG. 4A and the configuration of FIG. 4B are almost the same, so that each component shown in FIG. 4B is the same as that of the corresponding component of FIG. 4A. Reference numerals are denoted by "'", and detailed description is omitted. However, the second groove 50 'is formed in a direction that is generally vertically upward, as the hand 16' is changed in posture in the vertical position. Hereinafter, the differences from the configuration of FIG. 4A will be mainly described.

As shown in Fig. 4B, the operating shaft 46 'of the hand support member 18' is positioned at the position B1 'when the hand 16' grips the finished component 2 at position A1 '. . When the back spindle 41 releases the grip of the part 2 and retracts from the state in which the hand 16 'grasps the part 2, the part 2 moves from the back spindle 41 to the hand 16'. Is passed. Next, by the drive of the rod cylinder 32 ', the holding unit moves away from the rear main shaft 41 sideways obliquely upward along the guide direction G' of the linear guide 24 '(in the illustrated example). Top left). When the operating shaft 46 'moves to the position B2' in front of the corner portion of the guide groove 50 ', the component 2 gripped by the hand 16' moves to the position A2 '.

The moving direction of the operating shaft 46 'gradually changes upward from the direction G' toward the direction G 'along the shape of the guide groove 50'. In accordance with the change in the moving direction of the operating shaft 46 ', the hand support member 18' is rotated clockwise in FIG. 4B about the point 20 ', and the hand 16' is inclined. The operating shaft 46 'moves from the position B1' to the position B4 ', and the component 2 gripped by the hand 16' in accordance with the movement of the operating shaft 46 'causes the position A1 along the trajectory T'. Move from 'to position A4'. When the component 2 is positioned at the last position A4 ', the posture is changed to the vertical position in which the hand 16' is approximately vertically downward.

When the holding unit moves obliquely upwards, the conveyance shuttle 14 is arranged at a height according to the position of the hand 16 'by a predetermined stand 15 or the like so as to be close to the hand 16' in the vertical position. .

By setting the holding unit to move upward at an angle, the cutting oil scattered in the component separator 12 'can be configured to not flow down to the conveyance shuttle 14 side.

The conveyance shuttle 14 comprises the 2nd conveyance means which receives a component from a holding unit. As shown in FIG. 5, the conveyance shuttle 14 has the component water position 52 which receives the said component 2 from the hand 16 of a vertical position, and the outside of the automatic lathe 1 with the component 2. The linear conveyance path in the channel portion 8 by means of a drive means 56 such as a rodless cylinder, between the component unloading position 54 where the component 2 can be watered with the palletizer. It is provided along the 58 so that reciprocation is possible. As shown in FIG. 6 and FIG. 7, the transfer shuttle 14 supports the component accommodating member 60 and the component accommodating member 60 that can receive the component 2 from the hand 16 so as to be movable up and down. The support member 62 and the base 64 in which the support member 62 is provided are provided.

Shocks such as an end stopper 66 and an oil damper, such as a rigid rod, which respectively position the transfer shuttle 14 at the part water position 52 or the part discharging position 54 at both ends of the transfer path 58. An observer 68 is installed (shown in FIG. 6 only for the part water position). The end stopper 66 contacts the base 64 to regulate the movement of the transfer shuttle 14. The shock absorber 68 contacts the base 64 just before the base 64 contacts the end stopper 66 to mitigate the impact between the base 64 and the end stopper 66.

As shown in FIG. 6 and FIG. 7, the component accommodating member 60 of the conveyance shuttle 14 is moved upward by the lift mechanism in order to facilitate the component water with the hand 16 in the component accommodating position 52. Is lifted up. The lift mechanism includes the above-described support member 62, the pivot 70 fixed at one end to the support member 62, the pivot plate 72 fixed at the other end of the pivot 70, and the pivot plate 72. 1st cam follower 74 and 2nd cam follower 76 and the cam stopper 78 fixed on the conveyance path 58 are provided. The cam stopper 78 is made of a bolt or the like which is able to contact the first cam follower 74 in a substantially horizontal direction. The part accommodating member 60 and the base 64 have a U-shape when viewed from the side. The support member 62 is located inside the part receiving member 60 and the base 64. The pivot 70 penetrates the hole 80 provided in the base 64. The support member 62 and the pivot plate 72 are pivotable about the base 64 with the pivot 70 as the shaft center. The first cam follower 74 and the second cam follower 76 are formed as protrusions provided on opposite sides with the pivot 70 on the pivot plate 72 interposed therebetween.

As shown in the substantially center of FIG. 5, the component accommodating member 60 of the conveyance shuttle 14 when moving between the component water-system position 52 and the component carrying out position 54 is based on self-weight. It is in a state of being lowered to approach the base 64. As shown in FIG. 6, when the conveyance shuttle 14 approaches the component water position 52 and the first cam follower 74 contacts the bolt 78, the movement of the first cam follower 74 is stopped. Regulated. On the other hand, the base 64 moves until it comes in contact with the end stopper 66. By moving the base 64 in a state where the movement of the first cam follower 74 is restricted, the support member 62 pivots the pivot 70 with the pivot plate 72 and the pivot 70 therebetween. Then, it rotates counterclockwise in FIG. The component accommodating member 60 which is supported by the support member 62 is raised by turning counterclockwise of the support member 62. As the part receiving member 60 is lifted up, the hand 16 in the vertical position and the part receiving member 60 come close to each other. By releasing the holding of the component 2 by the hand 16 in a state where the hand 16 and the component receiving member 60 are in close proximity, a smooth water system of the component is formed between the hand 16 and the component receiving member 60. Is done.

When the water system of the parts is completed and the transfer shuttle 14 moves to the left side of FIG. 6, the turning plate 72 and the support member 62 are driven by the axis 70 by the weight of the parts receiving member 60. It rotates clockwise, and the component accommodating member 60 falls again. When the conveyance shuttle 14 is close to the component conveyance position 54, and the bolt 78 '(refer FIG. 5) corresponded to the cam stopper 78 contacts the 2nd cam follower 76, it is as mentioned above. The component receiving member 60 is raised. Since the bolt 78 'is the same as the ascending operation at the part water position 52 except for the contact with the second cam follower 76, the detailed description is omitted. As the part receiving member 60 is raised at the part discharging position 54, the water system of the smooth part between the robot etc. (not shown) which transfers a part to the palletizer 3, and the conveyance shuttle 14 is carried out. Can be carried out.

In addition, the component accommodating member 60 is in the lowered state except when the conveyance shuttle 14 is at the component inherited position 52 or the component discharging position 54. Therefore, the height of the cover structure 6 of the part which the conveyance shuttle 14 in the state which the component accommodating member 60 passed down can pass low. By making the height of the cover structure 6 low, the maintenance space with respect to a spindle and a tool post can be ensured widely, and the workability around a spindle and a tool can be improved.

A urging means (not shown) such as a spring for urging the component accommodating member 60 downward is provided, and the component accommodating member 60 is forcedly lowered at a position other than the component water position and the component discharging position. You may make it become.

The 2nd conveyance means can also be set as the belt conveyor which can mount components from the component separator 12, and this belt conveyor can also be provided in the said channel part 8. As shown in FIG. The conveyor belt may be continuously operated or may be intermittently transported so that parts do not collide with each other. However, as for the component including the mirror-finished surface, the conveyance by means in which the part of the component in contact with the other member is limited to the predetermined portion, like the above-mentioned conveyance shuttle, is suitable. In addition, since the conveyance shuttle can accurately align the attitude of the parts to be carried out, the watershed for the palletizer can be smoothly performed as compared with the case where the transport shuttle is carried out in a random attitude.

In this component discharging device 10, a part of the gripping unit is changed in posture so that all the components, including the movement of the gripping unit, are accommodated within a range inside the outer vicinity of the edge of the mount, and the components of the gripping unit are It does not protrude from the range to the working side. Specifically, since the component separator 12 is normally disposed in the cover structure 6 on the operation front side of the machine tool 1, the component separator 12 is disposed on the rear spindle 41 so as not to interfere with visual inspection and operation of the operator. It does not protrude largely upward from the position of the workpiece 2 held. In addition, the component separator 12 is not a simple configuration such as an arm swinging with respect to one point, but the linear movement of the component conveyance path (trace T in FIG. 4A) from the rear main shaft to the conveyance shuttle 14 is performed. The structure is not largely separated from 24). Therefore, since the guide direction G of the linear guide 24 extends obliquely downward from the rear main shaft toward the front of the machine tool, the space occupied by the component separator 12 including the parts is obliquely downward from the substantially center of the rear main shaft, and is conveyed. It can be limited to the space above the shuttle 14. Therefore, the component separator 12 can be accommodated compactly in the place which does not interfere with the work in the cover structure 6. In addition, since the component separator 12 "grasps" the processed component and conveys it from the rear spindle 41, a separate chute, which is a movable cylindrical object, is installed below the rear spindle to "roll and drop" the component. It is suitable for the conveyance of parts that need to be handled with care, as compared to the "floating" structure.

The conveyance shuttle 14 is housed inside the cover structure 6 except where it is located near the part unloading position 54, and the part unloading position 54 is outside the cover structure 6 but is an automatic lathe. It is arrange | positioned in the place (left side toward the operation surface 7 in FIG. 1) other than the front surface (operation surface) 7 side of (1). Therefore, the component of the integrated component carrying-out apparatus 10 does not protrude on the operation surface side of the automatic shelf 1, and the safety of an operator is ensured, and when it is used in combination with facilities, such as a palletizer, You can save space.

According to this invention, by changing the attitude | position of the 1st conveyance means by a posture change means, a 1st conveyance means is moved from the outer vicinity position of the edge of the mount side of the front side used as the moving direction of the 1st conveyance means in a machine tool. It is accommodated in the inner range. Therefore, the component discharging device can be installed compactly by suppressing a minimum protrusion from the edge portion of the mount. In particular, by providing the first conveying means so as not to protrude from the mount end edge, the machine tool provided with the component discharging device 10 can be provided with the same occupied area as a machine tool without a conveying device for parts. In the case where the component discharging device does not protrude from the end edge of the mount, the cover can be made almost the same as the end edge of the mount, and the size of the cover can be the same size as that of a machine tool without a conveyance device for the part.

By setting the moving direction of the first conveying means to the front side that becomes the transverse direction of the main shaft, the height of the entire machine tool can be suppressed without having to configure the component discharging device above the main shaft, thereby improving workability around the main shaft and the tool. You can. In particular, when the first conveying means is moved obliquely downward from the main shaft, the second conveying means can be disposed below the first conveying means, so that the part can be easily passed to the second conveying means, and from the main shaft transverse direction It is also good in terms of visibility of the main axis. In addition, when the first conveying means is moved obliquely upward from the main axis, good visibility of the main axis from the main axis transverse direction can be obtained.

Specifically, the first conveying means is simple and easily configurable by a hand holding a component, a linear member for pivotally supporting the hand, and a linear guide for moving the linear member in the horizontal direction along the moving direction of the hand. In addition, it is possible to smoothly convey the parts without applying an extremely large impact or the like, and even when the first conveying means is an arm structure having a chuck or a hand, the arm structure can be easily accommodated within the above range. Further, the attitude changing means comprises a guide groove provided between the fixed side and the hand side for the movement of the linear motion member, and an operating shaft engaged with the guide groove, and the hand is moved in accordance with the movement of the linear motion member by the linear guide. The attitude changing means is easily formed by forming a first groove parallel to the moving direction of the linear motion member and a second groove continuously formed to intersect the first groove in the guide groove to change the attitude between the horizontal direction and the vertical direction. Can be configured.

On the other hand, by making the 2nd conveyance means into the form of the conveyance shuttle comprised so that a reciprocating movement between a part water system position and a component carrying out position is possible, between a 2nd conveyance means and a 1st conveyance means, or a 2nd conveyance means and a palletizer. Since the impact on the part and the like can be suppressed in the water system of the part between the receiver of the part lower than the second conveying device such as the above, it is possible to easily carry out the part that needs to be handled particularly carefully. have.

Moreover, by providing a lift mechanism to the second conveying means, the water system of the parts between the second conveying means, the first conveying means or the palletizer can be performed more smoothly.

In addition, when the second conveying means is a belt conveyor capable of intermittent transport operation, it is possible to obtain an original effect such that the second conveying means can be made simple.

In the machine tool provided with the component carrying device of the present invention, even when the first conveying means carries out conveying the parts to the front side of the machine tool, the outside of the mount end edge where the first conveying means becomes the front side of the machine tool.
