An unloading chute 174 for unloading the work 1 on the unloading stand 173 to a device in a subsequent process is provided.

The above means 11 to 16 and the robot 17
The respective cylinders or actuators are operated by compressed air supplied via a pipe, a switching valve and the like (not shown), and perform respective required operations.

Next, the operation of the deburring system for the gear end portion and the entire deburring apparatus according to the above embodiment will be described. (1) The work 1 is carried into the pedestal 26 by the carry-in means 11. (2) The lateral movement cylinder 59 is operated to insert the burr raising tool 50 into the hole portion 2 of the work 1 at a substantially central position in the width direction. (3) The pedestal 26 is raised by the lifting / lowering cylinder 37, and the pedestal 26 stops rising at the position where the gear-shaped teeth 51 of the tool 50 are engaged with the teeth 3 of the work 1 by burr. (4) The deburring tool 50 is rotated by the geared motor 60, and reciprocated by the mechanical valve 74 and the sliding cylinder 65 for a predetermined time. (5) During this movement, the gear-shaped teeth 51 of the burr raising tool 50 cause the burr 8 to be turned back to the tooth groove 7 side of the tooth portion 3 of the work 1.

(6) After a predetermined time has passed, the burr raising tool 50 is retracted by the lateral movement cylinder 59,
The pedestal 26 is lifted to the rising end by the lifting cylinder 37. (7) From the position of the rising end, the transfer robot 17 transfers the work 1 to the position of the deburring means 14. (8) In the middle of this conveyance, the operator stops at the position just above the discrimination pad 85 and confirms the front and back surfaces of the work 1 and the end surface groove 6 by the proximity switches 86 and 87. (9) The work 1 is processed as follows depending on whether the result of the confirmation is normal “yes”, inside out “no”, or “unknown” that does not belong to either of these. In the case of “yes”, the work 1 is conveyed to the position of the deburring means 14 by the robot 17. In the case of "no", the work 1 is conveyed to the position of the reversing means 15, is reversed here, and then is returned to the above (8) to be redone.
In the case of "unknown", the work 1 is conveyed to the unknown goods unloading place 24, and when the photoelectric switch (not shown) and the photoelectric switch (not shown) of the reflecting plate, which are opposed to each other with the work sandwiched, are turned on for a certain period of time, the work is treated as an unknown goods. To be done.

(10) The work 1 conveyed to the position of the deburring means 14 is clamped by the chuck 94. (11) The hand 17a of the robot 17 escapes to the outside of the interference, the main housing 100 descends by the lifting cylinder 97 of the deburring means 14, and the deburring tool 104 moves the gear tooth 51 of the work 1 into the deburring tool 90. It meshes with the end of the tooth portion 3, and the chuck 94 rotates in this state, and this rotation causes the burr 8 to fall toward the end face groove 6 side. (12) At the same time when the main housing 100 is lowered in (11), the deburring tool 92 attached to the holder 129 is lowered by the speed regulator 130 at a timing adjusted in advance with respect to the lowering of the deburring tool 90. The tip of the picking tool 92 enters the end surface groove 6. (13) When the chuck is rotated while the work 1 and the deburring tool 90 are in mesh with each other, the deburring tool 90 also rotates.

(14) By the rotation of the deburring tool 90, the burrs 8 in each tooth groove 7 of the work 1 are successively tumbled, and the deburred tool 92 splashes and removes the deburred tools 8. go. After repeating this operation twice within an arbitrary time, the rotation of the chuck 94 is stopped, the clamp by the chuck claw 94a is released, and the work 1 is held by the hand 1 of the robot 17.
It is gripped by 7a and conveyed to the next step. (15) Here, the work 1 having the end surface groove 6 on the back side as well.
Is conveyed to the position of the reversing means 15 and reversed, and then confirmed by the discrimination pad 85. Here, the proximity switch 8
When it is judged as “unknown” by 6, 87, it is transported to the unknown-item delivery point 24. In the case of "yes", (1
0) to (14) are repeated. (16) The work 1 that has been deburred is cleaned by the cleaning means 1.
The robot 17 is transported to the position 6 and is mounted on the cleaning table 165 and undergoes cleaning for an arbitrary predetermined time while making a reciprocating angular motion. After cleaning, the robot 17 is transferred to the oil draining table 168 and waits for removal when the oil is drained. After being conveyed onto the table 173, one cycle of deburring is completed. (17) The work 1 on the carry-out waiting stand 173 is carried out to the subsequent process by the carry-out means 18 as appropriate.

In the case of the above embodiment, a series of each means 1 is provided within the reach of the hand 17a of the robot 17 arranged at the center.
Since 1 to 18 are installed on the common base 10, it is easy to automate a series of operations for deburring from loading and unloading of the work 1, and as the deburring tool 50 and deburring tool 90. By using a small spur gear type, the life of the tool can be greatly extended and stabilized, there is an advantage that reliability and reliability of deburring are increased, and quality is stable. By adopting the throw away tip, it is possible to shorten the tool replacement time and stabilize the replacement accuracy and facilitate management.By using pneumatic pressure as the cylinder and actuator drive source in each means, deburring work can be performed. This has the effect of facilitating labor saving and automation, and quick operation.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the invention. For example, the elevating and lowering support member 38 of the burr raising means 12 may be moved in a direction intersecting with the vertical direction instead of moving up and down in the vertical direction,
The angle between the work 1 and the axis of the deburring tool 90 is 45
The deburring tool 92 may be of any suitable size other than degrees.
Other than the throwaway chip can also be used as.
