Description

[Detailed Description of the Invention] The present invention relates to an automatic pallet changing device for a machine tool attached to a machining center.

An automatic pallet exchange device is a peripheral device attached to a machining center. The pallets stored in this device are carried into the machining center and installed, and once machining is completed, they are carried out and returned to this device again.
Chips of various materials such as steel, casting, aluminum, etc. processed by the machining sender and coolant are loaded onto the pallet and returned. Workers clean chips and coolant when changing workpieces on pallets. At this time, chips and coolant are stored in an oil pan attached to an automatic pallet exchange device. Conventionally, the oil pan has been fixed to the equipment, which has caused the disadvantage and inconvenience that chips from various processed materials and coolant are mixed together and cannot be sorted or separated.

It is an object of the present invention to provide an automatic pallet changing device that can improve the drawbacks of the conventional devices and can sort and separate machining chips and coolant made of different materials stored on an oil pan.

The automatic pallet changing device of the present invention includes an oil pan that is hinged to the main body of the device and can swing vertically to the left and right, a drive device that swings the oil pan to the left or right as necessary, and It is characterized by having a plurality of buckets arranged below the pan, each containing chips of different materials and coolant.

Hereinafter, the present invention will be specifically explained with reference to embodiments illustrated in the drawings. FIG. 1 shows a front view of an embodiment of the present invention, and FIG. 2 shows a plan view. In the figure,
Reference numerals 1 and 2 are pallets, 3 is a main body of the apparatus that accommodates the pallets 1 and 2, and 4 is a support supporting the main body 3. The oil pan 5 is hinged to a hinge shaft 6 provided on the support column 4, and can swing vertically in left and right directions, and the oil pan 5 can be moved to the left or right as required by cylinders 7 and 8 provided below. Make it swing in the direction. Buckets 9 and 10 are arranged below the oil pan 5 and receive and store chips of different materials and coolant from the oil pan 5, respectively. The rocking and tilting of the oil pan 5 causes chips and the like accumulated therein to fall into the bucket 9 or 10. The bucket is replaced for each different material.

That is, by swinging the oil pan 5 leftward or rightward, machining chips and coolant made of different materials can be sorted and separated. For example, when aluminum is machined, the oil pan 5 is swung to the left to store only the aluminum machining chips in the bucket 9.
When machining castings, by swinging the oil pan 5 to the right, only the chips from the casting process are dumped into the bucket 10.
to be accommodated.

As described above, according to the present invention, machining chips and coolant made of different materials can be easily sorted and separated.
