Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic press apparatus suitable for progressive processing aimed at producing a wide variety of small and medium-sized bolts.

In order to increase the operating efficiency of this type of press equipment, it is important to improve the efficiency of the nine setup operations that involve exchanging molds and materials. Equipment can be unmanned. There are advantages.

To make such press equipment unmanned.

An automatic mold changing device or the like may be used, but conventionally, 6 to 8 molds were used, so a special changing device was not required.

However, when the number of molds reaches several hundred, it becomes necessary to transport the molds in order to use conventional equipment more efficiently.

There arises a need to control unloading, exchange, and storage as part of the production operating system. At the same time, as the number of molds increases, the types of materials also increase, so there is a need to systematize the storage and exchange of these materials.

In view of the above, the present invention uses a computer to organically connect the various devices described above and a production control system, and operates not only the press machine but also its peripheral devices according to a production program created by the computer. The present invention provides an automatic press device that automatically creates programs and controls all setup and production work.

The present invention will be explained in detail below based on an illustrated embodiment.

FIG. 1 is an overall perspective view showing one embodiment of the present invention.
At the back of the press machine 1 equipped with a mold exchange device (not shown), there is a mold warehouse 2 and a mold warehouse in which hundreds of molds used in the press machine 1 are stored and held at predetermined positions. A transport device 2b for selecting and transporting molds in the mold warehouse 2 is provided, and the entrance 2a of the mold warehouse 2 and the discharge port 1a of the press machine 1 are connected via a mold transport device 3. Here, the mold warehouse 2 is constructed of a conventionally known rack building, etc., and the transport device 2b moves the molds to be used in the next processing to the starting end of the mold transport device 3 based on instructions from the computer 17. At the same time, the mold conveying device 8
The used mold that has been transported to the terminal end 8b is transported to a predetermined position and stored. Furthermore, the mold conveying device 8 is constituted by a kind of slat conveyor, and the used molds are transported to the transport station 1a after a series of processes of the press machine 1 are completed according to instructions from a computer, which will be described later. At the same time, this mold is transported at the terminal end ab't, and at the same time, a new mold that has been supplied to the starting end 8a and is waiting at a waiting point 3c on the way is transported to the transport station 1a.

Further, an example of the press machine 1 includes a material warehouse 4 consisting of a coil material warehouse 4a that stores a plurality of types of coil materials, and a fixed length material warehouse 4b that stores several types of fixed length materials. The material warehouse 4 and the press machine 1 are connected via a material supply device 5 and a leveler feeder 6. Note that the material supply device 5 serves as a subordinate to the loop feed device 5a for feeding the coil material to the leveler feeder 6, and is an adsorption type (magnetic type) for supplying a fixed length material to the leveler feeder 6 instead of this coil material. Or a vacuum) feed mechanism 5b is provided on the upper part, and the feed mechanism is selected and used depending on the type of material determined by a command from a computer 17, which will be described later. The coil material warehouse 4a has a plurality of coil material cassettes 4e that integrate a plurality of uncoilers, cutters, etc. wound with predetermined coil materials, and are slidably mounted on a slide rail 4c. The coil material facing the loop feeding device 5a is automatically switched based on instructions from the computer. Further, the fixed-length material warehouse 4b is made up of a stack of a plurality of types of fixed-length materials arranged side by side in the same direction as the moving direction of the coil material warehouse 4a.

By automatically moving this length material warehouse 4b along the guide rails 46, it is possible to change the type of length material supplied to the leveler feeder 6 via the suction type feed mechanism 5b. In short, the material warehouse 4 holds multiple types of coil-shaped and fixed-length materials, and one predetermined material is exchanged and delivered to the supply position to the press machine 1 based on instructions from a computer. The specific structures of the material warehouse 4 and the material supply device 5 are not limited to the structure shown in FIG. 1, but may be arbitrary. 7 is for the station, 8
is a controller that controls commands from the computer to the breath machine and each of the above-mentioned devices.

As shown in FIG. 2, the computer 17 includes a central controller 9 and a first storage device 1 composed of a floppy disk or the like.
0, a second storage device 11 such as a magnetic disk, and peripheral devices 12 such as a typewriter or CRT. , press machine 1. Mold conveyance device 8
゜Peripheral equipment 1 such as material supply device 5 and leveler feeder 6
It is also line-coupled with the control system of No. 3. 14 is an interface for the automated warehouse control system, and 15 is an interface for the machinery control system.
．． Commands are output to each device through 15.

The controller 8 is an independent type, and when the automatic press machine is in full automatic operation, it controls the press machine, peripheral equipment, molds, and materials based on the production program described later.

It consists of a display panel for displaying production quantity commands, a graphic panel for pattern checking that displays signals for the flow of operation as a system, and an operation control panel consisting of start buttons, stop buttons, switches, etc. during manual operation. There is. Therefore, the controller 8 can not only centrally monitor the status of fully automatic operation, but also operate the vehicle 9 manually, without the use of a computer.

The above-mentioned graphic panel for pattern checking is used to check whether the automatic press system is working as efficiently as possible, and it divides the operation flow of each part into dozens of steps and memorizes each step. The system compares it with the standard pattern that is available and advances the step only when it matches, ensuring continuous reliable operation. A signal is displayed on the panel when the patterns do not match, making it easy to find the defective part.

The computer 17 determines the production order based on the production plan data, as shown in the flowchart shown in FIG. Next, read the warehouse data, press basic data, mold data, and material data.

It inquires whether each device can produce based on the production order, automatically displays any inconveniences, and changes the production order. The production program is completed in this way, and can be output and displayed as appropriate through the CRT display. Production will begin based on this production program, but we will also take measures to accommodate changes in the production plan.
It is now possible to freely change the production order, production quantity, etc., and make new additions and updates.

The computer 17 instructs each device to prepare for production based on the production program. First, a command is sent to the mold warehouse 2 and material warehouse 4, and a command is issued to ship the molds and materials used for the first production. Based on this unloading command, the transport device 2b operates and the predetermined mold is transferred to the mold transport device 8.
After being carried out to the starting end 3a and carried into the press machine 1 by the mold conveying device 8, it is automatically positioned and clamped by an automatic exchange device.

Similarly, only predetermined materials are carried from the material warehouse 4 to the press material supply device. On the other hand, the press machine 1 has not only the necessary die-items for mold replacement and installation, but also the preliminary feed amount of material, feed pitch, production volume per unit length of material, plate thickness, planned production quantity, etc. Various data are supplied, and the press machine 1 is automatically adjusted based on these data.

As described above, when the preparation for production of the press machine and peripheral equipment is completed, the specified material is automatically supplied to the press machine 1 by the material supply device 5 and the leveler feeder 6, and production is started.

Furthermore, after the start of production, the products and the remaining materials are automatically sorted and transported to their respective predetermined positions.

Further, when production is started, the molds to be used for the next production are transported to a waiting point 8ci based on instructions from the computer 17 in preparation for the metal bud exchange.

Once the planned quantity has been produced, production will be stopped.

In the same manner as described above, the molds and materials necessary for the next production process are replaced, and production is restarted.

Thereafter, production is returned in the same manner.

In addition, current abnormality monitoring is performed using a graphic panel during the current transportation and exchange of molds, materials, and production operations of press machines and peripheral equipment. If an abnormality occurs in the operation, it will automatically stop and a signal will be displayed on the panel indicating the abnormality.
Notify the operator and wait for recovery through manual work.

On the other hand, the computer 17 calculates the cumulative production number for each mold each time each production is completed according to the production program.
Usage time and number of abnormalities.

The contents, etc. are recorded, and the length and weight of the materials used are calculated to determine the remaining amount.

It is determined whether or not there is a problem with the next production, and if there is a problem, it is printed out or displayed on a CRT to inform the operator, or it is supplied to the computer as warehouse data. Furthermore, when the day's production is completed, a 9-day report is automatically created and recorded so that the day's production can be seen at a glance, greatly reducing the labor of the workers, but in some cases unmanned operation is also possible. It has also become

Incidentally, FIG. 4 shows a production line system according to another embodiment, which in this case is equipped with a mold warehouse and a plurality of press machines.

As explained above, according to the present invention, not only press machine adjustments but also molds and materials can be automatically replaced according to the production plan, so there is no need to perform manual setup work as in the past. do not have. For this reason, in press work that requires a large number of setups, such as high-mix small-to-medium production, the use of computers makes it easier to create and change production programs, and greatly reduces worker labor.
The operating efficiency of the press machine can be improved by shortening the setup time, and in some cases, the press machine can be operated unmanned.

Furthermore, the present invention greatly contributes to improving the operating rate in that it facilitates the combined use of coiled materials and regular length materials in the production of a wide variety of products in medium to small quantities through progressive processing.
