Abstract

PURPOSE:To completely automatize a pallet translocating operation by providing a hook member positioning mechanism on an unmanned conveying vehicle on which a pallet having a hook member is loaded, and providing a pallet towing hanger and a sequencer on a machine tool. CONSTITUTION:A positioning mechanism 6 for moving a pallet 3 on which a workpiece 8 is loaded, in A-A' and B-B' direction, is provided on an unmanned conveying vehicle 5, while a hook member 1 is provided on the pallet 3. The pallet 3 which has been conveyed to the pallet receiving window 11 of a machine tool 10, is stopped in a position in which the pallet towing hanger 2 of the machine tool 10 agrees with the center of the hook member 1 of the pallet 3, by means of a sequencer 20. Then, as the pallet 3 is moved up to a position in which the hook member 1 can be engaged with the hanger 2, by means of the sequencer 20 and via the positioning mechanism 6, the pallet 3 is lifted up in the B direction by means of the positioning mechanism 6, and the hook member 1 and the pallet towing hanger 2 are engaged, to introduce the pallet 3 to the machining position of the machine tool.

Description

[Detailed Description of the Invention] [Summary] The pallet transfer system of the present invention loads a pallet containing workpieces and transports it to a pallet receiving window of a machine tool, and transfers the transported pallet to a pallet receiving window of a machine tool. The pallet is moved to the processing position of the machine tool using a hanger for towing the pallet, and the work of transferring the pallet to the machine tool can be streamlined.

[Industrial application field]

The present invention relates to a pallet transfer system in which a pallet containing workpieces is transferred and transferred to a machine tool using an automatic guided vehicle.

[Conventional technology]

It has long been the practice to load pallets containing workpieces onto automated guided vehicles and transport them to the machine tool's pallet receiving window, but this is not the case for pallets on the machine tool side.

I. Since the height of the receiving window differs depending on each machine tool, the transfer of Ballen 1~ from the automatic guided vehicle to the machine tool was performed manually by the operator.

(Problems to be Solved by the Invention) However, as described above, relying on manual operations for pallet transfer is inefficient, and particularly places a severe physical burden on the workers responsible for the transfer. There will be M.

The present invention has been made in order to solve such problems in the conventional pallet transfer process.

[Means for solving problems]

As shown in FIG. 1, the system for transferring a pallet to a machine tool according to the present invention is as follows: (1) A hook member 1 is provided on a pallet 3 containing a workpiece 8.

■Barn F that engages with the hook member 1 of the pallet 3 on the machine tool 10 and moves the pallet 3 to a predetermined processing position
eCitation hanger 2 is provided.

(2) The automatic guided vehicle 5 is provided with a pallet positioning mechanism 6 that adjusts the height position of the hook of the loaded pallet 3 to the height position of the hanger 2 for pulling the valet of the machine tool 10.

(2) Furthermore, a sequencer 20 is provided which sequentially controls the transportation of the automatic guided vehicle 5, the height adjustment of the valet positioning mechanism, and the movement of the pallet pulling hanger 2.

Automated measures are being taken.

[Effect]

In the valet transfer system configured in this way, the transfer of the pallet mounted on the automatic guided vehicle to the machine tool is completely automated.

〔Example〕

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 is a side sectional view of a main part showing an embodiment of the present invention.

As shown in the figure, the valet transfer system of the present invention is equipped with a baren!/positioning mechanism 6 that moves the pallet 3 on which the workpiece 8 is loaded in the direction of the arrow A-^'' or the direction of the arrow B-B'. Automatic guided vehicle 5 and Barrett 2 quotation hanger 2
The operation of each of these components is controlled by a sequencer 20.

The operation of each of these configurations will be explained below.

■The pallet 3 loaded on the unmanned 1st carriage 5 and transported to the pallet receiving window 11 of the machine tool 10 is transferred to the 1st floor carriage 5 under the control of the automatic guided vehicle by the sequencer 20. F
, it stops at a position where the center of the quotation hanger 2 and the center of the hook 1 match.

■Then, the positioning mechanism 6 of the automatic guided vehicle 5 is activated by the sequencer 2.
0 to move the pallet 3 to a position where the hook member 1 and the hanger 2 for pulling the pallet engage.

■Next, the positioning mechanism 6 is driven upward in the direction of arrow B, and the hook 1 of the pallet 3 and the hanger 2 for pulling the pallet are
engage with.

■By the above operation, pallet towing hanger 2 and hook 1
When engaged, the pallet pulling hanger 2 pulls the pallet 3 in the direction of arrow A under the control of the sequencer 20 and guides it to a predetermined processing position.

In this way, the automatic guided vehicle 5 is equipped with the pallet positioning mechanism 6 that moves the pallet 3 in the direction of the arrow A-8 or in the direction of the arrow B-B" and connects the pallet towing hanger 2 and the hook member 1. , the hook member 1 and the pallet pulling hanger 2 are engaged with each other regardless of the hanger standby position P.

In the figure, 10a is a roller for smoothing the movement of the transferred pallet 3, and 15 is a cutter turret equipped with a group of cutting tools for processing.

The automatic guided vehicle 5 is guided by guided vehicle guiding rails 7 buried in the floor surface 25 to move.

FIG. 2 is a perspective view of a main part showing an example of the shape of a hook member and a hanger for pulling a pallet, in which (a) shows a hook-shaped shape;
bl indicates a fitting shape, respectively.

Note that the fitting type shown in FIG. 2(b) is generally used when positioning the pallet 3 with high precision.

It should be noted that the pallet positioning mechanism 6 is not necessarily necessary since the position adjustment in the direction of the arrow A-A' can be covered by the movement of the hanger 2 for pulling the pallet on the machine tool side in the A-^' direction.

〔Effect of the invention〕

As explained above, the pallet transfer system to a machine tool according to the present invention has a barreso 1 guidance function on the automatic guided vehicle side,
Thanks to the hanger operation function on the machine tool side and the coordinated operation of the sequencer that controls each of these components, pallets can be transferred regardless of the standby position of the hanger for pulling pallets, making it possible to completely complete pallet transfer operations. can be automated.
