Abstract

PURPOSE:To eliminate an idle time of a treating device and reduce the number of trucks, by supporting a pallet on which an untreated work is constantly placed. CONSTITUTION:A pallet placed at the first station 6 is transferred to the second station 7 when the adjacent station becomes vacant. Then, a work-gripping member 9 of a taking-out mechanism 5 takes out the untreated work placed on the pallet located at the station 7, transfers the work to a working mechanism 4 to subject the work to a working treatment, and the worked work is placed on the pallet. When the treatment of the work placed on the pallet at the station 7 is completed, the pallet is transferred to the third station 8, and simultaneously, the pallet located at the first station 6 is transferred to the second station 7. During the treatment of the work placed on the pallet located at the second station 7, the truck 1 recovers the pallet placed on the station 8 and feeds it to a storehouse.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing system in which a transport vehicle transfers a workpiece to a processing device that automatically performs, for example, cutting processing.

In addition to installing a large number of processing devices (robots) that automatically perform processing such as cutting, casting, and pressing in one factory, it is also possible to transport workpieces between these robots and warehouses, etc. Automated systems equipped with powered vehicles have recently been actively developed. In order to increase the operating efficiency of the transport vehicle, the transport vehicle is normally configured to transport a large number of workpieces at once via pallets. However, if the number of transport vehicles is reduced, there will be a waiting time after the robot finishes processing a workpiece until the next unprocessed workpiece is supplied, making it difficult to improve the operating efficiency of the entire factory. There is a risk of being too lenient. On the other hand, if the number of conveyance vehicles is increased in order to prevent the idle time of 10 bots from occurring, the entire factory will be forced to work hard and the layout will become complicated, resulting in an expensive system.

The present invention has been made in consideration of the above-mentioned points, and aims to provide a processing system that can be operated with a relatively small transport vehicle, which reduces the idle time of each processing device.

The present invention features @1゜mug, each of which can hold a pallet;
A plurality of processing devices have second and third stage machines, take out the workpieces on the pallet of the second stage machine, process them, and place the processed workpieces on the pallets, and a A transfer mechanism that transfers the pallet, and a pallet with a workpiece mounted on it, are connected to J1'! A transport vehicle is provided that transports m between the storage location and each processing device d, and the transport vehicle delivers pallets on which unprocessed workpieces are placed to the first stage, and also places processed workpieces thereon. It is time and space that the pallet is received from the third station.

The present invention will be explained below with reference to illustrated embodiments.

The figure shows a part of a factory to which the present invention is applied, and processing equipment 43 is disposed at predetermined intervals on the side of the rail 2 through which the transport vehicle 1 passes. The processing device 3 is, for example, a lathe, a milling machine,
Approximately 50 casting machines, presses, etc. are installed in this embodiment, and each of them is controlled automatically and operates independently of each other.

Each processing device #3 Fi, for example, a processing mechanism 4 that performs cutting, and a take-out mechanism 5 that supplies a workpiece to this processing mechanism 4.
and a first, second and third station 6, 7, 8 provided near the rail 2.

The extractor mechanism has 5 pieces, is rotatable around point P, and
The work gripping member 9 is supported so as to be freely retractable.

When this workpiece gripping member 9 takes out the unprocessed workpiece on the pallet of the second station 7, it retreats toward the turning center P, and
After turning to the processing mechanism 4 side, it protrudes and delivers the workpiece to the processing mechanism 4. However, when the processing of the workpiece by the lever is completed, the workpiece gripping member 9 takes out the processed workpiece from the processing mechanism 4, retreats toward the turning center P, and then moves to the second
It pivots toward the stage rack 7 side, projects again, and places the processed workpiece on the pallet of the second stage rack 7. That is, the work gripping member 91d: moves forward and backward along the arrow A on the second stage 7, rotates along the arrow B from the second station 7 to the processing mechanism 4O, and rotates along the arrow B. In the vicinity of , it moves forward and backward along arrow IIICK.

Rabbit, 1. A transfer mechanism 10 is provided over the second and third stage stages 6, 7.8. Transfer machine $1410
U: When the pallet is transferred between stages 6 and 7.8, there is no pallet at the third station 8, and the processing of the workpiece on the pallet at the second stage 7 is completed. , this pallet is transferred to the third stage Hyakuten, and when the pallet is supplied to the second station 7 and a pallet with unprocessed workpieces is supplied to the first stage station 6, the pallet is is transferred to the second station 7. Tsumari, these stage signs 6 and 7
．． 8 holds one pallet each, and the first stage 6 holds a pallet with unprocessed workpieces placed on it, and the second stage 7 holds a pallet with unprocessed workpieces placed on it. , each holds a pallet on which 8 rivet-processed workpieces are placed at 3 stations.

The transport vehicle moves along IFi rails 2 and transports pallets 11 between a warehouse (not shown) and each processing device 3. In this example, one transport vehicle is coated with two gold films,
Each pallet 11 is transported one bale at a time, and the pallets 11 are loaded and unloaded using conventionally known forks (not shown).

Since the present embodiment has the following configuration, it operates as follows to process the workpiece.

The transport vehicle 1 carries out a pallet 11 containing unprocessed workpieces from the warehouse, moves along the arrow, and supplies the pallet 11 to a predetermined processing device 3. The transport vehicle 1 transports the pallets 11 to the processing device 3.
The pallet on which the processed workpiece is placed is either returned to the warehouse or sent to the third stage station 8 of one of the processing apparatuses 3 to pick up the pallet on which the processed workpiece is placed. The pallet placed on the first stage loading station 6 is placed in the second stage loading station 7 when the adjacent second stage loading station 7 becomes empty.
will be transferred to. Therefore, the work gripping member 9 of the take-out mechanism 5
takes out the untreated workpiece of pallet soil from the second station 7, delivers it to the processing mechanism 4, performs processing 1, and places the processed workpiece on the pallet. By repeating this operation, until the processing of all the workpieces on the pallet is completed, the pallet on the 3rd station 8 is immediately taken out from the transport vehicle IK and placed on the 1st stage 6. A new coverlet will be supplied to Send 1. Second
When the processing of the work on the pallet of stage V7 is completed, this pallet is transferred to the third stage 18, and at the same time, the pallet of station 6 is transferred to the second station 7.

During the processing of the workpieces on the pallets in the second stage, day 7, the first transport vehicle 1 collects the pallets on the third stage 8 and transports them to the warehouse.

Therefore, the second stage is n7! Since the pallet carrying the unprocessed workpieces is held, the play time of the processing device 3 can be substantially eliminated, and even if the number of conveyance vehicles is small, such a play time can be achieved.
It becomes possible to realize operation without I. In addition, since the workpiece gripping member 9 does not pass over the first and third stage 6.8, the inspector does not interfere with the workpiece gripping member 9, and the stage according to tl et al. Word 6
The workpiece on #8 can be safely inspected.

In the above embodiment, the transport vehicle 1 transports the pallets 11 one by one, but it is also possible to transport a plurality of pallets at the same time.

As described above, according to the present invention, it is possible to substantially eliminate the idle time of processing equipment, reduce the number of conveyance vehicles, and obtain an inexpensive processing system with a high operating rate. Wife the effect.
