Technical Field

The present invention relates to a conveyor device having a conveyor having an arm capable of gripping a workpiece, the arm being movable between the inside and the outside of a machine tool.

Background

A machining apparatus is known in which a conveyor for conveying a workpiece is disposed adjacent to a side wall of a machine tool. In japanese patent laid-open publication No. 2017-177287, an arm of a conveyor moves between the inside and the outside of a machine tool through a window formed in a wall surface of the machine tool, and exchanges workpieces.

In this processing apparatus, a rack for storing a plurality of workpieces may be disposed beside the conveyor. The arm of the conveyor holds the workpiece from the rack, takes the workpiece out, and feeds the workpiece into the machine tool. The processing device is provided with a safety fence surrounding the conveyor and the material rack. The safety fence is provided with a door for an operator to take out and put in the workpiece relative to the material rack.

The platform 54 is guided by the 2 nd guide portion 53 and slides with respect to the movable portion 50. With the 1 st rack 49, the 2 nd rack 63, and the pinion 52, the amount of sliding of the platform 54 is twice as large as the amount of sliding of the movable portion 50.

As shown in fig. 7, a notch 45a is provided at a corner portion on the rear end edge side of the 1 st fixing portion 45, and an engaging portion 54b that engages with a tip end portion of the notch 45a is provided at a rear end portion of the platform 54.

The platform 54 is open at the center, and the platform 54 is provided with a 3 rd receiving portion 56 (see fig. 9) outside the opening edge.

As shown in fig. 10 to 12, the front plate 57 has a handle 57a at the center, and the front plate 57 is connected to the side surface of the distal end side portion of the movable portion 50 by a connecting portion 64. The connecting portion 64 has a lateral plate portion 64c extending along the rear surface of the front plate 57, an upper plate portion 64d, and an abutting portion 64e abutting against the side surface, and the abutting portion 64e has a long hole 64a extending in the front-rear direction.

The side surface is provided with female threads 50a, and a screw 64b penetrating the long hole 64a is fastened to the female threads 50 a.

Wheels 59 and an adjusting portion 60 are provided at four corners of a lower end portion of the 1 st case 41. The 1 st housing 41 is movable in the front-rear-left-right direction by the wheels 59, and after the 1 st housing 41 is disposed at a predetermined position, the operation of the wheels is suppressed by the adjustment portion 60. The height can be adjusted by the adjusting portion 60.

The 1 st case 41 and the 2 nd case 35 are different in front-rear length. As shown in fig. 1, the total front-rear length of the pullout portion 42 and the 1 st case 41 when the pullout portion 42 is pulled out to the front side is equal to or less than the front-rear length of the 2 nd case 35.

In the above-described conveyor 5, the handle 57a is pulled out from a state where the platform 54 is located at the rear portion of the 1 st housing 41, and the movable portion 50 is slid with respect to the 1 st fixing portion 45 by the 1 st guide portion 51. The movable portion 50 slides in a supported state supported by the roller 47. With the rack-and-pinion configuration, the amount of sliding of the platform 54 is twice as much as that of the movable portion 50. As a result, the table 54 is projected from the cover plate 41c, and the tray 55 in which the workpiece 6 is fitted is placed on the table 54, which is in the state shown in fig. 1. Then, the front plate 57 is pushed toward the cover plate 41b, so that the movable portion 50 slides along the 1 st fixed portion 45, and the platform 54 moves rearward. That is, the pullout portion 42 is movable in the front-rear direction in which the 1 st fixing portion 45 extends. The rear end surface of the movable portion 50 abuts against the stopper 61, and the tip end portion of the notch 45a of the 1 st fixing portion 45 engages with the engaging portion 54b provided on the platform 54. This can suppress the forward and backward movement of the platform 54, and the drawer 42 does not move forward during vibration.

The sensor 62 is connected to the control device 19. When the sensor 62 detects the rear end surface of the platform 54, the control device 19 acquires information indicating that the sensor 62 detects the rear end surface of the platform 54, and operates the conveyor 30. The arm 32 moves backward under the control of the controller 19, enters the 1 st housing 41 through the opening 41a, grips the workpiece 6 on the magazine 55, and takes out the workpiece 6 from the magazine 55. The arm 32 moves forward, enters the machine tool 1 through the opening 35a, and places the workpiece 6 on the table 20. The machine tool 1 machines a workpiece 6.

After the workpiece 6 is machined, the table 20 is moved toward the 2 nd housing 35 side, and the arm 32 grips the workpiece 6. The arm 32 moves backward, and the workpiece 6 is placed on the magazine 55. The next workpiece 6 is also machined in the same manner. When the machining of all the workpieces 6 on the magazine 55 is completed, the operator pulls out the front plate 57, and the table 54 projects from the cover plate 41c to exchange the workpieces 6.

During machining, the machine tool 1 sprays a coolant onto the workpiece 6 to cool the frictional heat. The coolant adheres to the workpiece 6, and when the workpiece 6 is taken out and put in between the machine tool 1 and the housing 4 by the arm 32, the coolant may flow down. The cooling liquid is collected in the receiving portion 3 of the housing 4 by the receiving portion 56. The cooling liquid is collected by the 1 st receiving unit 7 disposed below the conveyor 30 via the 2 nd receiving unit (not shown) disposed below the substrate 43. The cooling liquid is recovered to a liquid sump.

When the conveyor 30 is maintained, the conveyor 30 moves to the front side, and the operator removes any one of the cover plates 35b to 35 e. When the storage body 4 is to be maintained, any one of the cover plates 41b to 41g is removed. The cover plates 35b to 35e and the cover plates 41b to 41g are not limited to those that can be attached and detached. In addition to these cover plates, other removable cover plates may be provided. Each side of the 1 st case 41 and the 2 nd case 35 may not be divided into a plurality of cover plates.

When the transport device 5 is first attached to the machine tool 1, if a deviation occurs between the jig 24 in the machine tool 1 and the position of the workpiece 6 when the table 54 is disposed on the rear side of the drawer 42, the workpiece 6 may not be gripped by the arm 32 and the workpiece 6 may be taken in and out.

In the present embodiment, as shown in fig. 13, the mounting plate 44 can be tilted with respect to the base plate 43, and the position can be adjusted by the elongated hole 44c and screwed. Therefore, the offset can be eliminated.

The front plate 57 is also rotatable in the front-rear direction, and is screwed to the side surface of the movable portion 50 with the position thereof adjusted by the elongated hole 64a, thereby preventing the front plate 57 from being displaced with respect to the cover plate 41c into which the front plate 57 is fitted.

The jig 24 and the tray 55 in the machine tool 1 can be prevented from being displaced from each other. Therefore, the arm 32 can be prevented from failing to grip the workpiece 6.

The operator can adjust the position of the table 54 without adjusting the positions of the 1 st and 2

nd housings

41 and 35, and the start-up time of the machining device 10 at the initial installation can be shortened.

The start-up time can be shortened even when the position of the conveyor 5 is changed.

(embodiment mode 2)

The transport apparatus according to embodiment 2 has the same configuration as the transport apparatus 5 according to embodiment 1, except that the tray 66 of the drawer 42 can be attached to the table 65 at an angle.

As shown in fig. 14, the platform 65 has a pin 65a at the center of the rear end edge portion and a plurality of female screws 65b in the front-rear direction at the left and right end edge portions.

The tray 66 has substantially the same size as the deck 65, a through hole 66a through which the pin 65a passes is provided in the center of the rear end edge portion, and a plurality of long holes 66b corresponding to the female screws 65b and extending in the left-right direction are provided in the left and right end edge portions. After the tray 66 is positioned by inserting the pin 65a through the through hole 66a, the tray 66 is attached to the stage 65 by fastening the plurality of screws 66c to the female screw 65 b. The tray 66 has the elongated hole 66b, and therefore can be fixed to the platform 65 at an angle. That is, the pin 65a, the female screw 65b, the through hole 66a, the long hole 66b, and the screw 66c constitute a fixing structure, and the tray 66 can be attached to the platform 65 so as to be rotatable about the pin 65a as a fulcrum.

The pin 65a and the through hole 66a are not limited to those provided in the center of the rear end edge of the platform 65 and the tray 66, and may be provided in the corner and the center of the platform 65 and the tray 66.

In the present embodiment, when the conveyor 5 is misaligned when it is attached to the machine tool 1, the table 65 can be tilted with respect to the tray 66, and the position can be adjusted by the elongated hole 66b and the screw-fixed, thereby eliminating the misalignment.

The occurrence of positional deviation between the jig 24 and the magazine 55 in the machine tool 1 can be suppressed, and the arm 32 can be prevented from failing to grip the workpiece 6.

The position of the table 54 can be adjusted without adjusting the positions of the 1 st and 2

nd housings

41 and 35, and the start-up time of the processing apparatus 10 can be shortened.

The recovery time when resetting the transport device 5 due to the movement of the machine tool 1 can also be shortened.
