Embodiment An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In the drawings, the same parts are designated by the same reference numerals.

FIG. 1, FIG. 2 and FIG. 3 are a side view, a top view and details of a work supply portion of a work supply / discharge device showing an embodiment of the present invention, respectively. Supply / discharge device
100 has a first shaft, that is, a shaft 10, which is slidable in the axial direction by a hydraulic cylinder 6 connected to one end. This axis
A work pressing member that presses the chuck on the unloader side, that is, a pressing member 10a is provided at the tip portion 10b of 10 as described below. A pin 13 is planted near the other end of the shaft 10. As can be seen in FIG. 2, the pin 13 is the lever 11
Is engaged with and guided by the long hole 11a provided at one end of the. The lever 11 is pivotally supported by a shaft pin 12 fixed to a fixing member 23 at a substantially central portion. A long hole 11b is provided at the opposite ends of the long hole 11a with the shaft pin 12 interposed therebetween. Long hole 11b
Is fitted with a pin 14 which is provided on a tubular sleeve member 20 which covers the outer periphery of the second shaft, that is, the loading shaft 8 and is slidable independently of the loading shaft 8, and is guided thereby. There is. The long holes 11a and 11b are provided with different phases in the longitudinal direction due to the cam action. As is apparent from the above configuration, the lever 11 can swivel around the shaft pin 12.

The loading shaft 8 and the third provided substantially parallel to it.
Of the shaft, that is, the unloading shaft 9, is connected by a connecting member 18 at one axial end of each.
It apparently slides integrally in the axial direction. The hydraulic cylinder 7 is connected to one end of the unloading shaft 9 fixed to the connecting member 18. Therefore, the loading shaft 8 and the unloading shaft 9 are simultaneously driven in the axial direction by the hydraulic cylinder 7 via the connecting member 18.

An intermediate member 22 extending in the axial direction is interlocked with an end of the loading shaft 8 opposite to the connecting member 18 in the axial direction. The other end of the intermediate member 22 is used for loading a work. A first work guide member, that is, a guide member 3 is provided. Therefore, the loading shaft 8, the intermediate member 22, and the guide member 3 can apparently move integrally in the axial direction. The guide member 3 has a substantially disc shape, and its outer diameter is set to be slightly smaller than the diameter of the substantially cylindrical inner diameter portion of the work W. Therefore, the guide member 3
It can easily enter the inner diameter portion of the work W and hold it. Further, the sleeve 20 is provided at the end opposite to the lever 11,
It has a work pushing member 19 that pushes the work W in the axial direction by contacting one edge portion of the work W in the axial direction. As is clear from the above configuration, the guide member 3 and the work pushing member 19 can move independently in the axial direction.

Like the loading shaft 8, the unloading shaft 9 is also operatively connected to the unloading substantially disk-shaped guide member 5 via an intermediate member 24 extending in the axial direction. Therefore, the second work guide member, that is, the guide member 5, is
By driving the hydraulic cylinder 7, it can be moved back and forth in the axial direction.
The diameter of the guide member 5 may be substantially the same as that of the guide member 3.

Here, the shape of the work W will be briefly described.
For example, the work W such as a conical inner ring has a substantially cylindrical inner diameter portion and a substantially cylindrical outer peripheral portion having a flange portion at one edge in the axial direction in the present embodiment. The applicable work is not limited to such a shape, and may be at least hollow and preferably has a cylindrical inner diameter portion. For example, it may be a work having a polygonal inner diameter portion. Almost any shape can be used for the outer circumference.

A part of each of the above components is fixed to the base 21. A cover 4 for supplying a work is rotatably supported on the base 21 by a mechanism (not shown) so as to face the guide members 3 and 5. The movement of the cover 4 will be briefly described with reference to FIG. The cover 4 is provided with an elevator 17 interlockingly with it, and when the elevator 17 is driven by a mechanism (not shown) and moves up, the cover 4 also moves up to take the lifted position 4 '. When the elevator 17 rises, the work W at the supply position is pushed upward, rides on the table 25, rolls on it, is placed on the bevel 16, and is arranged at a position where it can be supplied to the guide member 3. Incidentally, the cover 4
And the elevator 17 is preferably driven in conjunction with the hydraulic cylinders 6 and 7. In this example,
The cover 4, the elevator 17, and the bevel 16 constitute a vacuum supply means.

A support member 40 is fixed to the base 21, and the support member 40
The sleeve member 2 for inserting the loading shaft 8 into the hole 40a of the
0, and the unloading shaft 9 is guided and supported in the hole 40b.

Referring again to FIG. 1, the loading chuck member, that is, the chuck 1 faces the loading guide member 3 and the unloading chuck 2 faces the unloading guide member 5. It is arranged. The chucks 1 and 2 are driven by a mechanism (not shown), but it is preferable that the chucks 1 and 2 are also driven in conjunction with the two hydraulic cylinders 6 and 7. Both the chucks 1 and 2 for loading and unloading have a diameter slightly smaller than the diameter of the inner diameter portion of the work W in order to hold the inner diameter portion of the work W, that is, substantially the same as the guide members 3 and 5. Has a diameter of. Chuck 1
The chuck 2 and the chuck 2 may be chucks having the same mechanism or different chucks. The chucks 1 and 2 are fixed to the base 101.

The shaft 10 has a pressing lever 10a extending from the tip portion 10b for pressing the work.
It is pivotally supported at the tip portion 10b of 10 and is swingable around that. The pressing lever 10a is swingable between a pressing position for pressing the rear end portion 15 of the unloading chuck 2 at the time of unloading a work and other positions.

The operation of the work supply / discharge device 100 of the present invention described above is performed as follows. First, as shown in FIG. 3, the work W supplied from the work W supply device (not shown) is
It is lifted by the elevator 17 and placed on the bevel 16. At this time, since the cover 4 is rising at the same time as the elevator 17, the axial end surface of the work W is in contact with and held by the cover 4, and the axial position of the work W is determined. In this state, the guide member 3 driven by the hydraulic cylinder 7 advances in the axial direction and enters the inner diameter portion of the work W placed on the bevel 16 to hold the work W at the inner diameter portion. After that, when the cover 4 and the bevel 16 are separated from the work supply position, the work W is held only by the guide member 3. Guide member 3 in this state
The position of is indicated by the broken line 3a in FIG. In this state, the loading chuck 1 approaches the guide member 3 and substantially contacts the guide member 3 by a mechanism (not shown). After that, the hydraulic cylinder 6 operates and the sleeve 20 moves forward in the axial direction. Accordingly, the work pushing member 19 moves forward accordingly, abuts on the axial end surface of the work W, and pushes the work W in the axial direction. Transfer, that is, supply to the chuck 1 for loading.

When a predetermined working operation is performed on the work W after the loading is completed, the work W is transferred to the unloading chuck 2 (or the chuck 1 by a mechanism not shown).
Comes to the unloading position). Chuck 2
When it reaches the position facing the unloading guide member 5, the hydraulic cylinder 7 is driven again to advance the guide member 5 in the axial direction. When the guide member 5 reaches the position where it is almost in contact with the chuck 2 (the position indicated by the broken line 5a in FIG. 1), the cylinder 6 operates and retracts in the axial direction. As the cylinder 6 moves backward, the work pressing member 10a comes into contact with the rear end 15 of the chuck 2 and presses it. As a result, the stopper 2a interlocked with the rear end portion 15 retracts in the axial direction, and the work W is fitted into the guide member 5, that is, discharged. Therefore, the unloading work is completed.

As can be seen from FIG. 2, when the cylinder 6 works and the shaft 10 retreats in the axial direction, the sleeve 20 interlocked with it by the lever 11 advances in the axial direction, so that the retreating operation of the shaft 10 and the guide members 3 and 5 are performed. It is performed in conjunction with the forward movement of.

(Effect of the Invention) According to the work supply / discharge apparatus of the present invention described above, the following effects can be obtained.

Since the work is held by the inner diameter of the work, the posture of the work is stabilized and the workability is improved during the work of loading and unloading the work. Especially in the automatic turning process of conical inner ring etc.
Accidents due to discharge mistakes are eliminated, and the operation rate of work is improved.
