2. Description of the Related Art Conventionally, many FMSs using a stacker crane have been provided. However, since many of these systems are operated and controlled by a centralized control unit, it takes time and cost to build the system when building the system, and it is necessary to build it from the beginning as a large-scale system. The method is easy. Therefore, there is a problem that it is not suitable as an FMS that uses a stacker crane that is a system-up stacker crane that is to be constructed in the medium or small scale or expanded in the future.

Therefore, a machining unit having a function of exchanging tools and workpieces, and automatically selecting a machining program according to the type of a workpiece to be carried in and out to carry out workpiece machining, and a plurality of machining units can be additionally arranged. Development of unmanned processing equipment that enables independent distributed operation is desired.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to solve the problems.
It is intended to provide unmanned processing equipment in which multiple processing units can be additionally installed and each is capable of independent distributed operation.

[0005]

The present invention is provided with a machining unit having a function of automatically selecting a machining program according to the type of a workpiece to be carried in and out to carry out the workpiece machining. It is an unmanned processing facility with independent distributed operation that is connected to a monitor that monitors the operating status of each processing unit even if multiple expansions are installed.

[0006]

According to the present invention, each machining unit having a function of automatically selecting a machining program according to the type of the workpiece and performing the workpiece machining can perform independent distributed operation, and a plurality of expansion units can be freely arranged as needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments shown in the drawings will be described below. Figure 1
Is a perspective view of the stacker crane and the entire system showing the device of the present invention, FIG. 2 is a perspective view of the stacker crane according to the present invention, FIG. 3 is a perspective view of a pallet rack, FIG. 4 is a perspective view of a setup station, and FIG. FIG. 6 is a perspective view of the vertical buffer station, FIG. 6 is a perspective view of the horizontal buffer station, and FIG. 7 is a block diagram showing the entire system and control system.

FIG. 1 shows a stacker crane 1 and two vertical and horizontal machining units 2, 3 and a setup station 4,
A system comprising a vertical buffer station 5, a horizontal buffer station 6, and a pallet rack 7 provided in front of the processing units 2 and 3 is shown. In the pallet rack 7, various kinds of processed and unprocessed works are attached to a pallet and stored, and a designated pallet carrying the unprocessed works is provided by the stacker crane 1 at the front of each processing unit 2, 3. It is carried into the mold buffer station 5 or the horizontal buffer station 6 and processed. Then, the pallet of the processed work is stored in the original pallet rack 7 by the stacker crane 1. The setup station 4 is used to attach and remove various kinds of processed and unprocessed works to and from the pallet, and is performed manually by an operator.

Next, each member will be described. FIG. 2 is a perspective view of the stacker crane 1, showing two rails 10 and 1.
A carrier truck 12 is mounted on the carriage 1, and a drive unit composed of a servo motor SM and a speed reducer 14 is engaged with the traveling rack 13 to travel the carrier truck 12. A fork 16 of an elevator 15 that moves up and down by a chain 17 connected to a servomotor is provided on the carrier 12 and is controlled by an onboard control panel 18. In the pallet rack 7 shown in FIG. 3, the leveling block 20 is fixed with anchor bolts 19. In the drawing, three layers are stacked, and an oil pan 21 and a gutter 21A for receiving coolants dripping from each pallet are provided at the bottom.

FIG. 4 shows the setup station 4, in which the rotary table 22 rotates once every 90 degrees. LU1 is
Pallet ID reading unit, 23 is pallet I
This is the D tab. The vertical buffer station in FIG. 5 is provided with a table 24 for transferring pallets to and from the stacker crane 1, and a table 26 for turning 90 degrees from a horizontal posture to a vertical posture by a rotary unit 25. Palette change between the machine and this machine. The buffer cylinder C1 and the APC cylinder C2 are driving members. FIG. 6 shows a horizontal buffer station (shirt-tle type) 6, which has high-speed swing arms 27 at both ends.
28, the pallets on the horizontal tables 29, 30 are pallet changed between the stacker crane 1 and this machine. The horizontal buffer station (shirt tortle type) 6 is provided on the left and right horizontal tables 29, 30 with respect to the machine.
Move left and right to position.

FIG. 7 shows the entire system and a block diagram, and the pallet ID and the tool ID are provided in the magazine section of each processing unit 2 and 3, the work inlet and the setup station. Incidentally, each of the processing units 2, 3
Includes an NC controller 40 and an automatic programming system 50 using FA Tomato (trade name of our software).
Equipped with a monitor 60 and stacker crane 1
It is connected by a relay line such as S232C.

However, each machining unit having a function of automatically selecting a machining program according to the type of the workpiece to perform the workpiece machining is capable of independent distributed operation, and a plurality of expansion units can be freely arranged as required. The operating status of each processing unit that operates in a distributed manner can be collectively monitored by a monitor. Further, since the vertical buffer station 5 or the horizontal buffer station 6 is provided at the front of each processing unit 2 or 3, even for a work having a short processing time, the pallet is loaded into each processing unit 2 or 3. It can be carried out smoothly without stagnation.

It is needless to say that the present invention is not limited to the above-mentioned respective embodiments, and that design changes can be further made within the scope of the invention. In each of the above embodiments, the processing unit 2,
The number of 3 can be appropriately expanded.
