The present invention relates to an apparatus for automatically loading and unloading a workpiece on a chuck of a machine tool, and in particular, automatically loading and unloading a workpiece to enable automatic loading and unloading of a workpiece regardless of the size and type of the workpiece. Relates to a device.

The machine tool has a spindle for rotating the workpiece, and the spindle is provided with a chuck for chucking the workpiece. Therefore, if the spindle is rotated while the workpiece is in the chuck, the tool will turn or mill the workpiece.

As such, two conveyor systems are required to load the workpiece into the chuck and to take out the workpiece.

However, when the size or type of raw materials changed, these conveyor systems had to be modified as a whole.

For example, in the processing line of a brake disc applied to a brake device of a vehicle, when changing the size of a brake disc, normal production response is possible only by changing a line production machine or a large part of a machine related to a workpiece size. In addition, even if the type of workpieces, such as a brake drum, changes, all the line production machines had to be changed.

Accordingly, the present invention is to solve the problems of the prior art as described above, even if the size of the material is different, the automatic loading of the workpiece flexible to change the size and type of the workpiece so that it can be easily loaded or taken out to the chuck without changing the production line And the purpose of providing a carrying device.

Specific means of the present invention for achieving the above object,

As a device for loading the air workpiece into the chuck of the machine tool and at the same time to remove the workpiece from the chuck to discharge to the next processing line,

Lifting means disposed close to the chuck and moving the workpiece to a predetermined position;

Loading means for positioning the atmospheric material placed at a predetermined position of the lifting means on the chuck while rotating and advancing;

Is disposed on one side of the loading means is characterized in that it comprises a guide means for receiving the processing material discharged by the loading means to guide the other processing line.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual view of the automatic workpiece loading and unloading apparatus of the present invention, Figure 2 is a conceptual diagram showing three-dimensional, Figure 3 is a block diagram of a stopper device applied to the present invention.

1 to 3, the lifting unit 30 for moving the workpiece (work waiting to be processed) material (work waiting for processing) to a predetermined position on one side of the chuck 22 installed on the main shaft 20, as shown in Figs. ) Is located. For example, the lifting unit 30 may be mounted on the headstock 10.

The lifting unit 30 controls the housing 32 having a guide passage through which the atmospheric workpiece is guided from the input position A to the standby position B, and the height of the atmospheric material placed at the standby position of the housing 32. Stoppers 34 and 35 and index plungers 37 for exchanging the positions of the stoppers 34 and 35.

The enclosure 32 is provided with a sensor (not shown) for detecting the input position (A) of the material to control the loading unit 40 to be described later. In FIG. 1, the atmospheric workpieces W1 and W2 charged to the enclosure 32 have different diameters, and show that the corresponding atmospheric workpieces are fitted to the standby position B by the stoppers 34 and 35. have.

One stopper 34 is configured to have a relatively shorter length than the other stopper 35. Therefore, the relatively short stopper 34 serves to position the center of the relatively large workpiece W2 at the standby position B, and the relatively long stopper 35 moves the center of the small workpiece W2 to the standby position ( Position B).

At this time, the index plunger 37 serves to rotate the upper disk 36 to which the stoppers 34 and 35 are fixed, so that the positions of the stoppers 34 and 35 are changed.

That is, when the index plunger 37 is rotated away from the lower disc 38, the upper disc 36 rotates about the shaft 33 to change the positions of the stoppers 34 and 35.

Reference numeral 40 denotes a loading unit.

The loading unit 40 loads the chuck 22 by waiting for the workpiece placed in the standby position B of the housing 30 to the chuck 22 and at the same time the chute which will be described later with the processed workpiece held by the chuck 22 ( 60).

That is, the loading unit 40 moves the workpiece (b1) to the fixed chuck position while positioning the atmospheric workpiece (W1 or W2) on the chuck 22 while rotating and advancing. will be.

The loading unit 40 includes a drive unit 44 for rotating and advancing the rotating shaft 42, and a pair of swing arms 46 connected to the end of the rotating shaft 42 at an angle (120 degrees). And a plurality of grippers 49 and 50 connected to respective ends of the swing arms 46 and 47 to chuck material.

Reference numeral '60' is a 'suit' disposed on one side of the loading unit 40.

The chute 60 receives the processing material discharged by the gripper 49 and guides it to the machining line, and has a chute guide 62 inclined in the carrying out direction.

The operation of this embodiment configured as described above will be described.                     

First, "C" and "E" denoted by capital letters in FIG. 1 are the original positions of swing arms 46 and 47, "D" is the chucking position of swing arm 46, and "F" is the position of swing arm 47. It shows a carrying out position.

First, in the state where the swing arms 46 and 47 are in the positions (standby positions) of "C" and "E", for example, when a small diameter atmospheric workpiece W1 is introduced into the enclosure 30, the sensor not shown in FIG. This is detected and transmitted to the driving unit 44 of the loading unit 40 as a 'chucking' operation signal. Subsequently, the standby work W1 is lowered and stopped by the stopper 35 to stay in the standby position B. FIG.

Next, after the rotational shaft 42 is advanced, it rotates clockwise in FIG. 1 so that the swing arms 46 and 47 are positioned at positions "B" and "D", respectively.

The rotary shaft 42 then retreats to hold the atmospheric workpiece W1 waiting at the "B" position with the gripper 49 of one swing arm 46. At this time, the other swing arm 47 is chucked to the chuck 22 by the gripper 50 to catch the finished workpiece.

Then, the rotating shaft 42 moves forward again. Thus, the workpiece W1 is released from the enclosure 30 and the processed workpiece is released from the chuck 22.

Then, the rotating shaft 42 again rotates 120 degrees counterclockwise. Thus, swing arms 46 and 47 are placed at positions "D" and "F", respectively.

Then, the rotating shaft 42 moves backward. Therefore, the workpiece W1 in the air held by the gripper 49 on one swing arm 46 is loaded on the chuck 22 to perform chucking and at the same time, the gripper 50 on the other swing arm 47 on the gripper 50. The workpiece is placed in the chute guide (60). In this state, when the gripper 50 is opened, the processed workpiece is taken out to another processing line by the chute guide 62 of the chute 60.

When the loading and unloading of the workpiece W1 and the machined workpiece are automatically performed in the air as described above, the rotating shaft 42 moves forward and rotates clockwise to move the swing arms 46 and 47 to "C" and "E". It will return to the original position (standby position).

On the other hand, in order to process the large workpiece W2, the index plunger 37 is operated so that the relatively small stopper 34 places the large workpiece W2 exactly in the standby position B as described above. Automatic loading and unloading is performed by the operation.

As such, according to the present invention, even if the size or type of the workpiece to be processed is changed, the loading position can be kept constant at all times by operating the stopper. As a result, the chucking and the carrying out can be continuously performed. Automation is possible without change.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

As described above, according to the automatic workpiece unloading device, which is flexible for changing the size and type of the workpiece of the present invention, the loading position and the unloading position can be used as they are, even when the size of the workpiece is changed by operating a stopper device having a different height. It can be flexibly coped without changing the production line. Therefore, unlike the related art, it is not necessary to change the production line, thereby reducing economic and time loss.
