By the way, in recent years, it has been further required to shorten the processing cycle time. On the other hand, it is required to avoid increasing the size and complexity of the processing equipment.

In Patent Documents 1 and 2, since machining is performed on the indexing machine at each station such as polishing and grinding, the indexing machine is positioned and fixed at a predetermined position during machining of the workpiece, and is split during machining of the workpiece. The output board cannot be rotated. Then, due to the difference in processing time and the like at each station, the standby time may become long depending on the station, and there is a limit to shortening the cycle time.

The present invention has been made in view of these points, and an object of the present invention is that a plurality of processes and the like can be performed by one unit, and the cycle time can be shortened without requiring a complicated configuration. The purpose is to provide processing equipment.

In order to achieve the above object, in the present invention, the work piece is transferred to the processing section instead of on the indexing machine and processed so that the indexing machine can be rotated during the processing of the work piece.

It is designed to be processed closer to or further from W.

In this embodiment, the first processed portion 41 and the second processed portion 45 perform the same processing on the same portion of the same type of work W, and the first processed portion 41 will be described below. To simplify the description of the second processing unit 45.

Specifically, the first processing portion 41 rotates around the first tool rotating body 42 attached to the first tool box 34 and the axis extending in the third direction Z, and is the lower part of the first tool rotating body 42. A rod-shaped first spindle 43 attached to the first spindle 43 and a first grindstone 44 fixed to the lower end of the first spindle 43 are provided. Inside the first tool rotating body 42, a motor (not shown) for rotating the first spindle 43 and the like are provided.

For example, when grinding the inner surface of the work W, the first tool table 33 is lowered in the third direction Z using the first tool slide guide 32 as a guide to bring the first machined portion 41 closer to the work W. .. Then, the first grindstone 44 is inserted into the cylinder of the work W, and the first grindstone 44 rotates together with the first spindle 43 while abutting on the inner surface of the work W, and the work W on the first work table 24 Is rotated together with the first spindle 25, so that the inner surface of the work W is ground.

The second processing portion 45 is provided with a second tool rotating body 46, a second spindle 47, and a second grindstone 48.

The four holding portions 52 provided on the indexing board 5 each have the same shape, and a notch 53 is formed in a substantially U shape from the outer periphery of the indexing board 5 toward the rotation center axis 51. The notch 53 has a shape that allows the first spindle 25 of the first work table 24 and the second spindle 29 of the second work table 28 to enter and exit from the radial outside of the indexing board 5 in the first direction X. ..

The jig 10 is for supporting the work W on the indexing board 5, or the first spindle 25 and the second spindle 29, and is generally used, and detailed description thereof will be omitted. ..

FIG. 2 shows the first processing portion 41 and the second processing shown in FIG. 1 so that the first work table 24 and the second work table 28 approach the center of rotation of the indexing machine 5, that is, the center in the left-right direction. It shows a state of sliding in the first direction X from the position below the portion 45 to the position where it enters below the indexing board 5.

As shown in FIG. 2, when the work W is transferred from the holding portion 52 to the machining portion 4, the first work table 24 is slid in the first direction X so as to approach the rotation center axis 51 of the indexing board 5. Then, the right half of the first work table 24 (transfer mechanism 6) enters below the indexing board 5, the first spindle 25 is loosely fitted in the notch 53, and the upper surface of the first spindle 25 is the jig 10. It is in a state facing the lower surface. Then, the jig 10 is supported by the first spindle 25 so that the jig 10 can be moved from the holding portion 52. After that, the first work table 24 is slid in the first direction X so as to be separated from the rotation center axis 51 of the indexing board 5. By this operation, the first spindle 25 is pulled out from the notch 53 in the radial direction, and the jig 10 and the work W are separated from the indexing board 5. Further, the first work table 24 is slid to move the work W to a position where it can be machined by the first machining section 41.

The second work table 28, which moves to a position where it can be machined by the second processing unit 45, moves in the opposite direction in synchronization with the first work table 24 of the first processing unit 41, and is a symmetrical movement. Therefore, the description is omitted. The first spindle 25 and the second spindle 29 need only be inserted below the work W held by the holding portion 52, and are brought into contact with the notch 53 instead of being loosely fitted. May be good.

As shown in FIG. 1, the "position that can be machined by the first machining section 41" means that the first spindle 25 on the first work table 24 is on the front side of the first machining section 41 and is located on the first spindle 25. The position where the supported work W is below the first processed portion 41. Similarly, the "position that can be machined by the second machined portion 45" also means the position where the work W is below the second machined portion 45.

The work W is configured by providing a notch 53 in the holding portion 52 and sliding the first work table 24 and the second work table 28 in the first direction X between the indexing machine 5 and the processing portion 4. Can be transferred to the holding portion 52 and the processing portion 4 by linear movement in the left-right direction without lifting the above, so that the transfer can be performed with a simple configuration and in a short time.

As schematically shown in FIG. 3, the loading / unloading mechanism 7 is located at the front portion of the processing apparatus 1 at the radial outer position of the indexing machine 5 and at one of the holding portions 52 in the second direction Y. It is attached to the bed 2 adjacent to the holding portion 52. The carry-in / out mechanism 7 has, for example, a robot hand, and carries out the processed work W held by the adjacent holding portion 52 in the second direction Y from the holding portion 52, or holds the work W in the second direction Y. The unprocessed work W is arranged in the portion 52 so that it can be carried in.

The processing device 1 further includes a rotation mechanism (not shown) that rotates the indexing machine 5 in the clockwise direction. As shown in FIG. 1, the control unit 9 that controls the rotation mechanism includes a first rotation control unit 9a that controls the indexing board 5 to index and rotate in a 90 ° clockwise direction, and the indexing board 5 is a clock. A second rotation control unit 9b for controlling the index rotation by 180 ° in the clockwise direction is provided.

In order to distinguish and explain the four holding portions 52, in FIG. 3, in the state of the first step S1 described later, the holding portion 52 located adjacent to the first processing portion 41 is referred to as the first holding portion 52a. The holding portion 52 located adjacent to the second processed portion 45 facing in the first direction X is referred to as the second holding portion 52b. Further, the holding portion 52 located relatively away from the loading / unloading mechanism 7 in the second direction Y is the third holding portion 52c, and the holding portion 52 located adjacent to the loading / unloading mechanism 7 is the fourth holding portion 52d. And. That is, it will be described as 52a, 52d, 52b, 52c sequentially in the clockwise direction. Further, in order to distinguish and explain the work W, in FIGS. 3 and 4, in the first step S1, the work W held by the four holding portions 52a, 52d, 52b, and 52c is referred to as the work W1, W4, and W2, respectively. , W3.

Although the detailed method will be described later, the works W3 and W4 held by the third holding portion 52c and the fourth holding portion 52d in the first direction X are transferred to the first processing portion 41 and the second, respectively. The work W1 held by the first holding portion 52a, which is one holding portion 52 of the second direction Y, is carried by the loading / unloading mechanism 7 in a state of being transferred to the processing portion 45 and processed (S2 in FIG. 3). It is carried out and the unprocessed work W5 is carried into the first holding portion 52a (S3 in FIG. 3). Then, the indexing board 5 is rotated halfway, and the work W2 held by the second holding portion 52b, which is the other holding portion 52 in the second direction Y, is carried out by the carry-in / out mechanism 7, and the second holding portion 52b is carried out. The unprocessed work W6 is carried into the machine (S4 in FIG. 3). As a result, four work Ws can be carried in and out while two work Ws are being machined at the same time, and the carry-in / carry-out time required for one work W can be shortened. Therefore, one work W can be machined (carried out, processed and carried out). The cycle time related to (up to) can be shortened.

Next, the processing process of this embodiment will be described with reference to FIGS. 3 and 4.

First, as the first step S1, two workpieces W1 and W2 that have been processed by the first processing portion 41 and the second processing portion 45, respectively, in the first holding portion 52a and the second holding portion 52b in the first direction X, respectively. To hold. At the same time, in a state where the third holding portion 52c and the fourth holding portion 52d hold the two unprocessed workpieces W3 and W4 in the second direction Y, the indexing board 5 is rotated by the central axis 51. At the center, the first rotation control unit 9a rotates the index by 90 ° clockwise.

By this rotation, the third holding portion 52c and the fourth holding portion 52d are positioned in the first direction X, and the first holding portion 52a and the second holding portion 52b are positioned in the second direction Y.

Next, as the second step S2, the first work table 24 (transfer mechanism 6) is moved in the first direction X so as to approach the rotation center axis 51 of the indexing board 5, and the first spindle 25 is held in the third position. It is inserted below the work W3 held by the portion 52c (FIG. 2). Then, the work W3 is supported by the first spindle 25, and the first work table 24 (transfer mechanism 6) is moved in the first direction X so as to be away from the rotation center axis 51 of the indexing board 5, so that the work W3 is moved to the first position. It is transferred to the 1 processing section 41, and the first machining section 41 is lowered to start machining. In order to synchronize with this, the transfer mechanism 6 (second work table 28) is moved in the same manner, the work W4 of the fourth holding portion 52d is transferred to the second processing portion 45, and the work W4 is processed by the second processing portion 45. To start. The portion surrounded by the alternate long and short dash line in FIG. 3 indicates the state during this processing.

Next, as the third step S3, while the workpieces W3 and W4 are being machined in the second step S2, they are held by the first holding portion 52a, which is one holding portion 52 in the second direction Y. The work W1 is carried out by the carry-in / out mechanism 7, and the unprocessed work W5 is carried into the first holding portion 52a.

While the workpieces W3 and W4 are being machined in the second step S2, as the fourth step S4 following the third step S3, the indexing board 5 is centered on its rotation center axis 51, and the second rotation control unit 9b 180 ° index rotation in the clockwise direction. By this rotation, the positions of the four holding portions 52 are reversed around the rotation center axis 51, respectively. That is, the positions of the first holding portion 52a and the second holding portion 52b in the second direction Y are reversed, and the second holding portion 52b becomes a position adjacent to the loading / unloading mechanism 7. Then, the processed work W2 held by the second holding portion 52b, which is the other holding portion 52 in the second direction Y, is carried out by the carry-in / out mechanism 7, and the unprocessed work is carried out to the second holding portion 52b. Carry in W6.

Next, as the fifth step S5, the machining of the two workpieces W3 and W4 in the second step S2 is completed following the fourth step S4 while keeping the position of the indexing machine 5 in the state of the fourth step S4. Then, the transfer mechanism 6 (first work table 24 and second work table 28) is moved toward the center in the first direction X, respectively, and the processed works W3 and W4 are held in the third direction X in the first direction X. It is transferred to the section 52c and the fourth holding section 52d, respectively.

By the steps from the first step S1 to the fifth step S5, the processed work W1 to the unprocessed work W5 in the first holding portion 52a, and the processed work W2 to the unprocessed work in the second holding portion 52b. Replaced with W6. Further, in the third holding portion 52c, the unprocessed work W3 is in a processed state, and in the fourth holding portion 52d, the unprocessed work W4 is in a processed state.

Then, when the fifth step S5 is completed, the process returns to the first step S1 and the process up to the fifth step S5 is repeated to sequentially carry out the processed work W and carry in or process the unprocessed work W. Can be done.

By these series of steps, while the work W3 and the work W4 are being machined by the first machined portion 41 and the second machined portion 45, the machined works W1 and W2 are carried out and a newly unprocessed work W5 is carried out. , W6 can be carried in. Therefore, the time required to carry out the works W1 and W2 and the time required to carry in the works W5 and W6 can be shared with the processing time of the works W3 and W4. That is, since the carry-in / carry-out time of four works can be set during the processing of the two works W, the cycle time until the carry-in, processing, and carry-out of one work W can be shortened.

Further, since the first processing unit 41 can perform the processing work without interfering with the movement of the indexing machine 5, when the work W is processed by the first processing unit 41, the first processing unit 41 is required. It is also possible to change the orientation of the spindle 25 and the height and orientation of the first grindstone 44, and complicated machining is also possible. The same applies to the second processed portion 45 provided symmetrically.

Further, when machining the work W, it is required to improve the accuracy of positioning. However, in the present invention, the work W is not machined on the indexing machine 5, so that when the work W is machined on the indexing machine 5. In comparison, the indexing position can be easily controlled.

Further, in the present embodiment, the first processing unit 41, the indexing machine 5, and the second processing unit 45 are arranged side by side, and the front side of the processing unit 4 is an open space. The processing state of the work W can be visually recognized from the front side of the work W. Therefore, since the work such as maintenance of the processing unit 4 and replacement of the grindstone can be performed from the front of the processing apparatus 1 in which the work W is carried in and out, the workability is excellent. Further, since the holding portion 52 located on the rear side of the indexing board 5 which is a place where it is difficult to perform relatively complicated work becomes the standby position of the work W, the space on the rear side of the indexing board 5 is effective. Can be used for.

(Embodiment 2)
The second embodiment will be described with reference to FIG. In the second embodiment, only the parts different from the first embodiment will be described, and the description of the common parts will be omitted. In the second embodiment, the work W processed by the first processing unit 41 and the work W'processed by the second processing unit 45 are of different types, and different processing is performed. In order to further shorten the cycle time, it is preferable that the work W processed by the first processing unit 41 and the work W'processed by the second processing unit 45 have substantially the same processing time.

In the second embodiment as well, the same steps as those in the first embodiment may be repeated, and the processed work W is carried out and the unprocessed work W is carried in, and the processed work W'is carried out and unprocessed. If the work W'is carried in, the work W'will always be machined in the first machining section 41, and the work W'will be machined in the second machining section 45.

Therefore, for example, if the work W and the work W'are processed in the same part although the dimensions and shapes are partially different, and the processing times are almost the same, two types of workpieces are used in this one unit. Since it can be processed by the processing apparatus 101, it is excellent in production efficiency.
