Abstract

PURPOSE:To prevent a setting miss of control information of a molding apparatus, by providing the molding apparatus with a system for automatically changing control information, which commands the molding apparatus to do various operations, at the time when an adaptor of the molding apparatus is changed. CONSTITUTION:Top and bottom oces U, D are replaced, and an accessory apparatus, a feed bar 4, is also replaced. When a new feed bar 4 is connected to a feed bar driving apparatus 49, punched holes H1-H4 formed in the feed bar 4 come in contact with access sensors S1-S4 provided in a feed bar driving apparatus 4a. Then the access sensors S1-S4 operate to generate an input pattern corresponding to the combination pattern of the punch holes H1-H4. This input pattern is read via an interface 73, and has access to a memory 72 to read out control information in the memory 72 thereby giving the control information to control apparatuses 5, 6. When press is carried out, the driving of the feed bar 4 is started based on the information of the information apparatuses 5, 6.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a control information setting system, and more particularly to a control information setting system that includes an adapter device and a main device, such as a feed bar and its drive device in a transfer press device, etc. The present invention relates to a control information setting system that can automatically set control information for controlling various operations in a device at the same time as replacing an adapter device.

[Technical background of the invention]

First, referring to FIG. 1, an outline of a transfer press device, which is the premise of the present invention, will be explained.

In the figure, l is a transfer press device, 2 is a material supply device, 3 is a product take-out device, 4 is a removable feed bar, 4
A'b indicates a feed bar drive device to which the feed bar 4 is attached and which causes the feed bar to move forward, backward, up and down, etc.

First, the transfer press device 1 has a pair of slides la.
and a bed 1b, and lower molds D1 to D5 are arranged linearly at equal intervals on the upper surface of the bed 1b, corresponding to the desired pressing operation, and a slide 1a is provided.
Upper molds U1 to U5 are also linearly arranged at equal intervals on the lower surface of the mold.

Further, the feed bar 4 is mounted on a rack along the line direction of the transfer press device 1, and both ends of the feed bar 4 are connected to feed bar drive devices 4a-b. Further, clampers C0 to C5 are fixed to the lower surface of the feed bar 4 at equal intervals to the above-mentioned mold intervals.

Then, the lifting timing of the slide 1a, the material supply timing of the material supply device 2, the product takeout timing of the product takeout device 3, the conveyance timing of the feed bar 4,
The clamping and unclamping timings of the clampers CO to C5 are interlocked with each other, and the material supplied from the material supply device 2 is subjected to multi-step press processing in the transfer press device 1 and taken out by the product takeout device 3.

More specifically, the slide 1a moves up and down in accordance with the rotation of a crank drive mechanism (not shown), and when the crank angle is O.
Lowering movement between ° and 180 °, crank angle is 180 °
Perform a rising motion between ° and 360 °. Then, the material is transported while the crank angle is between 270° and 90°.

That is, in FIG. 2, the clamper C1 (i is an integer between θ and 5) is stopped at an intermediate position between the lower mold Di and the lower mold D (++1) when the crank angle is between 90° and 270°. . Then, when the crank angle passes through 270°, the feed bar 4 is activated, so that the clamper Ci retreats in the direction of arrow a and is positioned above the lower mold pi, and then descends in the direction of the arrow to lower it. Clamp the material on the mold Di. When the material is clamped, the clamper Ci rises in the direction of arrow C, moves forward in the direction of arrow d, and is positioned above the lower mold D (++1), and then descends in the direction of arrow e to transfer the material to the lower mold. D
Release onto (++1). After unclamping the material in this manner, the clamper C1 moves up in the direction of arrow f, retreats in the direction of arrow g, and returns to its initial position.

The new material is supplied from the material supply device 2 to the lower mold D1 by the clamper CO, and the material (product) is taken out from the lower mold D5 by the clamper C5.

When the conveyance of the materials and products is completed in this manner, the slide 1a descends and presses the materials on each of the lower molds. Therefore, by sequentially repeating the above operations, the material supplied from the material supply device 2 onto the lower mold Di is sequentially moved over the molds adjacent to the cloth and subjected to multi-step press processing, resulting in a product. The product is taken out by the product taking out device 3.

By the way, in the case of such general-purpose transfer press equipment, changes in the desired processing content involve changes in the shape and spacing of the upper and lower molds, as well as changes in the structure and spacing of the clamper, so it is usually not possible to change the desired processing content. Gently replace the feed bar 4 itself.

Also, at this time, changing the shape of the lower mold sometimes requires changing the amount of elevation of the feed bar 4, and changing the mold interval requires changing the amount of advance/retreat of the feed bar 4.
When changing the desired processing content, it is necessary to replace the feed bar 4 and also change the control information for specifying the amount of advance, retreat, elevation, etc. of the feed bar 4.

Conventionally, control information for specifying the amount of advance, retreat, elevation, etc. of the feed bar 4 was manually input directly from a digital switch on the operation panel, or this type of control information itself was assigned an identification number. The control information was stored in memory, and the control information was read out by inputting the identification number from the operation panel.

For this reason, conventionally, when changing the machining content, in addition to replacing the feed bar, it was necessary to separately specify control information for specifying the amount of advance, retreat, elevation, etc. of the feed bar 4. Not only is this complicated, but there is also the risk that the entire system may malfunction due to errors in inputting control information.

[Object of the invention] The present invention has been made in view of the current situation, and
For example, it is an object of the present invention to provide a control information setting system that can automatically set control information for specifying the amount of advance, retreat, elevation, etc. of a feed bar at the same time as replacing an adapter device such as a feed bar. purpose.

[Summary of the invention]

In summary, the control information setting system of the present invention is an apparatus that includes an adapter device such as a feed bar, which is replaced as appropriate depending on the desired work content, and a main device connected to the adapter device. , an identification code of the adapter device is attached to a connection point of the adapter device with the main device, an input means for reading the identification code is provided at a connection point of the main device with the adapter device; A storage device is provided in which control information for controlling various operations is stored in association with the identification code, and the control information is read out from the storage device in accordance with the identification code inputted from the input means. It is designed to control various operations according to the control information received.
When changing the processing content, various control information can be automatically obtained simply by replacing the adapter device.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

Reference numeral 6 in the figure indicates a control device that includes a microprocessor 61, a memory 62, and an interface 63, and this control device W6 controls the vertical movement of the feed bar 4 (arrows b and 6 in FIG. 2).
This is to control the amount of movement, speed of movement, activation timing, etc. regarding the movement in the directions of arrow C, e, and f. The output of the control device 6 via the interface 63 is amplified by the amplifier 64 to drive the DC motor DCM2 for raising and lowering the feed bar 4.

The operating state of this DC motor DCM2 is determined by the interface 63 as the output of the pulse generator PG2.
is fed back to the control device 6 via.

In addition, IIJ control devices 5 and 6, amplifiers 54 and 64, DC motors DCMI and DCM2, and pulse generator PCI
・For the PO2 feedback system itself, a conventionally known one can be applied.

Next, numeral 7 indicates a main control device that includes a CPU 71, a memory 72, and an interface 73, and the main control device 7 is for providing control information to the control device 5 and the control device 6 to control them.

The characteristic feature of this embodiment is that the main controller 70 memory 72 contains control information (advance amount, forward speed, forward timing, backward amount, backward speed, backward Data indicating timing, lifting amount, lifting speed, lifting timing, etc. and microprograms for control) are stored in memory areas allocated for each type of feed bar 4. Automatically specified at time of exchange.

The designation of the storage area of the memory 72 will be explained in more detail in the operation description below.

Further, 4 indicates the feed bar also shown in FIG. 1, and 4a indicates the feed bar driving device also shown in FIG.

A characteristic feature of this embodiment is that when the feed bar 4 and the feed bar drive device 4a are connected, the feed bar 4 and the feed bar drive device 4a come into contact with each other, and the feed bar 4 side is An identification code indicating the type of bar 4 is attached, and an input means for reading this identification code is provided on the feed bar drive device 4''a side.

The specific configuration of this input means can be selected from various types such as a barcode league, a magnetic tape league, a photoelectric sensor, a microswitch, a proximity sensor, etc. depending on the mode of identification code, but in this embodiment, As an example of this input means, a proximity sensor S is connected to the feed bar drive device 4a.
1 to S4 are provided, and punch holes H1 to H4 are provided as an example of identification codes at the locations of the feed bar 4 corresponding to the proximity sensors S1 to S4, and the proximity sensors S
1 to S4 are configured to determine the presence or absence of the corresponding punch holes H1 to H4 using binary logic (1.0).

As described above, in this embodiment, the proximity sensors S1 to S
4 and punch holes H1 to H4 are arranged for four each, so there are 24 combinations of cover turns obtained from the proximity sensors S1 to S4, that is, 16 types. Therefore, 16 types of feed bars 4 are arranged. It becomes possible to identify.

As described above, the memory 72 of the main controller 7 is configured to store control information corresponding to the type of feed bar 4 to be replaced in a memory area allocated for each type of feed bar 4. Therefore, the memory 72 can have up to 16 areas for storing control information.

Incidentally, FIG. 4 shows the correspondence between the combination cover turns of the proximity sensors S1 to S4 and the numbers of the memory areas prepared in the memory 72 for storing control information.

Next, the operation of this embodiment will be explained with reference to the above matters.

First, when changing the desired processing content, the lower molds D1 to D5 fixed to the bed 1b and the upper molds U1 to U5 fixed to the slide 1a are replaced, the feed bar 4 is replaced, and the feed bar 4 is replaced. By connecting the bar 4 to the feed bar drive device 4a, punch holes H1 to H4 provided in the feed bar 4 and proximity sensors S1 to S4 provided in the feed bar drive device 4a come into contact with each other. ) When the power is turned on from the operation panel (not shown), the proximity sensor S1
~S4 operates to generate an incoming cover turn corresponding to the combination pattern of punch holes H1~H4.

For example, if only the punch hole H4 is punched, the proximity sensors S1 to S4 generate an input cover turn (0001) as shown in FIG. device 7. The main controller 7 reads this input cover pattern via the interface 73, determines a read address based on this input cover pattern, and accesses the memory 72.

Therefore, from the memory area indicated by area number 2 of the memory 72, control information (data indicating advance amount, forward speed, forward timing, backward amount, backward speed, backward timing, lifting amount, lifting angle, lifting timing, etc.) The main control device 7 provides this control information to the control devices 5 and 6 via the interface 73 in accordance with the type of information.

Then, the control device 5 reads the control information given in this way via the interface 53 and stores it in the memory 5.
At the same time, the control device 6 reads the control information thus given through the interface 63 and writes it into the memory 62.

Thereafter, when the conditions for starting press working are completed, the main controller 7 communicates with the controller 5 via the interface 73.
and 6, and the control devices 5 and 6 start driving and operating the feed bar 4 according to the control information written in the memories 52 and 62, respectively.

Since the operation after starting the drive of the feed bar 4 in this manner is conventionally known, a redundant explanation will be omitted.

In addition, in the above, proximity sensors S1 to S1 are used as an example of input means.
Although we have shown an example using S4, various input means other than the above may be used as long as they correspond to the identification code attached to the feed bar, such as barcode readers, magnetic tape leagues, microswitches, photoelectric sensors, etc. can be used.

Furthermore, although the above example shows how up to 16 types of feed bars can be identified using a combination pattern of 4 bits, it goes without saying that if the combination pattern is made up of n bits, up to 2 degrees of types of feed bars can be identified.

In addition, although the embodiment in which the present invention is applied to the operation control of the feed bar of a transfer press device has been shown above, the present invention may be applied to other applications as long as the adapter device is replaced when changing the work content. be able to. For example, as an example of an adapter device, an identification code is attached to the mold,
(1) Die Hyde, (2) the number of rotations of the press, and (3) the feed length when using coil material as the material may be controlled.

Moreover, although the above explanation has mainly been given to the case where information for controlling the operation of the adapter device is set, it goes without saying that information for controlling the operation of the main device can also be set.

Furthermore, although the case where the adapter device operates with two degrees of freedom has been described above, it goes without saying that the present invention can be applied as is even if the degrees of freedom increase.

〔Effect of the invention〕

As explained above, according to the present invention, various kinds of control information are automatically set at the same time as the adapter device is replaced, and there is no need to separately manually set this type of control information. This not only saves time and effort, but also effectively prevents malfunctions caused by incorrect settings of control information.
