Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automatic pallet changing device that cleans a pallet attached to a workpiece processed by a machine tool or a workpiece before being processed by a machine tool. be.

Conventional technology of this type uses a pallet 103 as shown in FIG.
The workpiece 102 mounted on the machine tool 100 and processed by the machine tool 100 is placed in the bed 106 of the automatic pallet exchange device 101.
The vent 106 places the workpiece 102 attached to the pallet 103 on top, rotates in the direction of arrow A, and places the workpiece 10 in a position facing the reversible washer 104.
2, the workpiece 102 attached to a pallet 103 is inserted into the reversing type washer 104, the surroundings are covered, and the reversing device 105 turns the workpiece 102 over, allowing chips to fall naturally and coolant to be sprayed from a plurality of nozzles 107. Wash. On the other hand, the unprocessed workpiece 102a attached to the pallet 103a is inserted into the bed 10 of the automatic pallet exchange device 101 after the processed workpiece 102 is inserted into the reversible cleaning tillO4.
6 rotates in the direction of arrow A, and the workpiece 102a is transferred to the machine tool 1.
Automatic pallet exchange device 10 when it comes to the position opposite to 00
1's bet 106 is stopped and the workpiece 102a is machine tool 1.
It is attached to the turntable 100a of No. 00.

(Problems to be Solved by the Invention) However, in the prior art as described above, there is a problem that the installation space becomes large because both the automatic pallet exchange device and the reversing type washing machine are installed.

(Means and effects for solving the problem) In order to solve the above problems, the present invention provides a pallet that has a workpiece machined with a machine tool attached thereto, or a pallet that has a workpiece that has not been machined with a machine tool attached thereto. In an automatic pallet exchange device having a pet section for attaching one or both pallets, it is possible to attach pallets to the upper and lower surfaces of the pet, and the vent can be reversed so that it is placed in a position facing the pet surface. The automatic pallet changing device is characterized by being equipped with a cleaning nozzle.

(Example) Embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a side view of an automatic pallet changing device with a cleaning device of the present invention and a multifunctional machine tool related to this device, and Fig. 2 is an operation of the automatic pallet changing device with a cleaning device of the present invention and a multifunctional machine tool. It is a diagram showing the contents.

1 is an automatic pallet changing device) 1b, a drive motor Ia for reversing the plate Ib, and a power transmission bell) l
pallets 3a and 3b are detachably constructed on the upper and lower surfaces of the plate 1b.

Reference numeral 2 denotes a pallet cleaning device, and there are automatic doors 2a, 2b, and 2c that automatically open and close when loading and unloading pallet (baren) 3a, 3b, and a nozzle 4 below which sprays cleaning coolant.

The pallets 3a and 3b are attached by machining the workpieces attached to the pallets 3a and 3b using a multifunction machine tool equipped with a turntable 5a.

A guide bridge 6 is used for moving the pallets 3a and 3b between the multi-tasking machine tool 5 and the automatic pallet changing device 1.

7 is a setup station used for jig setup.

Next, the operation of the automatic valet changing device with cleaning device and the multifunction machine tool of the present invention will be explained with reference to FIG. In the figure (T
N table) shows the turntable 5a side of the multi-tasking machine tool 5, and (APC) shows the automatic pallet changing device Nl side.

At NOI, turntable 5 of compound machine tool 5
The workpiece 3-(1) attached to the pallet 3 on a is being processed, and the workpiece 3-(2) attached to the pallet 3 attached to the automatic pallet changing device 1 is on standby.

In NO2, workpiece 3 attached to pallet 3
- (1) is moved to the upper surface of the automatic pallet exchanger w1 after the processing is completed.

In NO3, the automatic pallet changing device 1 is reversed,
The workpiece 3-(1) that has been processed will be on the bottom side, and the waiting workpiece 3-(2) will be on the top side.

In NO4, the waiting work 3-(2) is moved onto the turntable 5a of the multitasking machine tool 5.

At No. 5, workpiece 1-(2) is being processed, and the automatic pallet changing device 1 is inverted with workpiece 3(1) still attached, and coolant is injected from nozzles 4a and 4b, and workpiece 3(1) is being machined. Washed.

At No. 6, work 3-(2) is being processed, and work 3-(1) is being carried out after cleaning.

At NOV, the workpiece 3-(2) is being processed, the automatic pallet changing device 1 is reversed, and the pallet 3 is cleaned.

At No. 8, the workpiece 3-(2) is being processed and the automatic pallet changing device 1 is reversed.

At No. 9, the workpiece 3-(2) is being processed, and a new workpiece 3-(3) is attached to the pallet 3.

At No. 010, the workpiece 3-(2) is being processed, the automatic pallet changing device 1 is reversed, the workpiece 3-(3) waits under the automatic pallet changing device 1, and returns to NOI.

(Effects of the Invention) Since the present invention has the above-described configuration, the space for installing the cleaning device and the automatic pallet exchange device is narrow, and since the pallet is cleaned before mounting the workpiece, chips are removed between the pallet and the workpiece. There is no biting and seating problems are less likely to occur.
