Abstract

PURPOSE:To permit safe and wider application of an installed press machine to small volume production of diversified kinds without removing the safety device thereof by disposing a circular table, a feed robot and an extractor on both sides of a bed. CONSTITUTION:The piston bar 91 and chuck 92 of an extractor 9 for extracting the formed work from dies advance, descend, and ascend after attracting the work in a pre-stage. When the bar 91 of the extractor retreats to the home position in succession, the chuck 92 releases the attraction to release the work. The arm chuck 82 of a feed robot descends, to attract the work W1 in the feed position and ascends, then the robot advances to the positioln of a die 4, and descends again upon arriving at said position and sets the work in the die 4. A circular table 7 rotates horizontally by a set indexing angle theta and stops after the work W in the next position moves to the feed position. The piston bar 81 of the robot which completes setting the work in the die 4 retreats to reset to the home position. A main body 1 operates to form the work set in the die 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically transporting workpieces in a press machine.
A device has been developed that automatically transports the corrugated material to and from the mold, i.e., supplies and takes it out.
With this, one worker can manage 2.3 machines? It's happening. However, as a conventional workpiece transfer device, there are two
A mechanism for supplying workpieces with a part of the workpieces slightly entering the inside of the vessel, and a dedicated magazine for accommodating the workpieces to be processed in a vertical column and then taking them out and supplying them from ship to vessel are installed.
? ffisa (t.

It is known that a device is provided with a take-out mechanism for carrying out a processed workpiece from behind the opposing bed. .

-)j, This J+((The press machine of I has phototube elements installed on both sides of the front of the bed to prevent danger to workers.
If a body part such as a hand or a foreign object enters the bed from this area, the 6 machine will not operate.3. The reality is that in order to combine the conveyance device with a ready-made press machine, the safety device must be removed.

Therefore, even if 499'7 of the workpiece is made into an automatic press machine, the fact that the press machine is not equipped with a safety device and is managed by one worker is a violation of the special law and is extremely dangerous. There's no need to say that.

Installing a magazine on the spatula to stack workpieces of a certain shape and supply them one after another is not a problem if the workpieces are flat and stable, but if the workpieces are non-flat and need to be stretched by UL or φ. Because it is not suitable for processing.

The Wl(If) magazine itself has to be replaced, making it troublesome to manufacture and replace the magazine.

-) There was a drawback of poor workability.

The present invention is provided in view of the above points, and includes a ready-made press machine? It is possible to reliably automatically transport the workpiece to the mold without removing this safety device, and to prevent the workpiece to be processed to be of a different type or shape, unstable or bulky. The purpose is to make it possible to apply this method by simply replacing a part of the workpiece storage section without having to replace the entire workpiece storage section.

One aspect of the present invention is to achieve the above object.

At a predetermined interval on one side of the bed, the installed work is horizontally rotated by a set indexing amount, and then sequentially fed.
The workpiece at the feeding position is removed from the mold on the bed H, and the molded workpiece is taken out from the mold and retreated by the lateral force of the other bed. This is a method for automatically conveying a workpiece in a press machine, characterized in that the workpiece is conveyed by a press machine.

Another feature of this invention is the lateral force on one side of the bed.

The workpieces placed at predetermined intervals are horizontally rotated by a set indexing amount (thereby sequentially moving and stopping at the supply position e~Cura table and the table H at its supply position mlf).
After the workpiece is integrated with the piston parr (the arm chuck is lowered and adsorbed and raised L), it is moved to the mold position on the bed 1-, and the 1-zo peg of the arm chuck "By removing the 111F, set up the feeding robot to set it on the bed, and place it on the other side of the bed.

A piston par with a chuck moves the workpiece, which has been formed by press processing, in the front direction, then descends and adsorbs it from the mold.
1. 1, then retreat and release the adsorption of the Ail-marked par chuck to set the take-out device that makes the T7-ri an angle γ square.
I got 1fffi.

Special? : An automatic conveyance system (z') for workpieces in a press machine.

The following drawings (to explain in detail, 1 is the press machine body,
2 is a bed, 6 is a mold die set, 4 is a metal plate, 5 is a safety device incorporating a photoelectric device installed on both sides of the front of the bed, 6 is a guide bin for the die set, 7
A regular table is installed on one side of the bed 2, and an auxiliary table 71 to support the workpiece W to be processed on the plane is installed on the opposite side of the bed 2. Specifically, the size of the circular table is, for example, 500 questions in diameter, and the number of indexes is θ.
The auxiliary table 7 is set so that it rotates at a rate of 60 degrees, which is obtained by dividing the circumference of the table 7 into six equal parts, and stops.
1 (This means that parts are provided to support the workpieces W1 to Wn at 60 degree intervals. 8 is a supply robot that sequentially feeds the workpieces W, to w, to the mold, The workpiece W1 is sucked downward by the piston parr 81 and the arm chuck 82ζ which is provided integrally with the piston parr 81. After the -CC fin is moved, the workpiece W1 is moved forward at the position of the mold 4 1Q:
J (Go down 9, release the suction of the arm chuck 82, apply seven strokes to the mold, remove the arm chuck, and then land to the original position) 1
(It is structured such that the piston par 81 and arm chuck 8□0 of the supply robot are moved downwards and downwards, and the operating mechanism for advancing and retracting is performed by a so-called mechanism and a link mechanism.9 is Press 1.,,',l
This is a device for taking out a workpiece W that has been formed by a machine.

The head l facing the circular table 7 written in ml.
, the piston par 91 and the chiseling part 92 integrated therewith are lowered from the position of the mold 4 from 7iJ forward C, suck the workpiece W, and then raised to the original position 7t. The plan is to release the workpiece by lfu+i by retreating to the position and releasing IVk. It should be noted that the chuck portion 92 of the I-pull device is i+r! Normally, it is possible to use an air chuck, but if the workpiece has a simple shape and is easy to take out, it is also possible to use an air chuck to pick it up and take it out.

Note that the circular table 7 and the supply robot 8,
The arrangement relationship with the IIQ output device 9 is taken into consideration based on the position e of the guide bin B of the mold die set filter.

Namely, 1) II - What is the position of νf and therefore the supply line? The gutter piston par 81 and arm chuck 82 may be obstructed by the guide bin 6e and may not be able to enter as far as the mold 4, which may be 7°C.

Therefore, if the guide bin 6 is provided on the front side of the die set 60, the circular table 7 as shown in FIG.
The supply robot 8 is located on the right (14 side) of the bed 2, and the take-out device 9 is located on the left (14) side. When the primary guide bin 6 is located at the front of the die set 6, the feed robot 8 is located at the back of the die set 6, as shown in Figure 2. The two take-out devices 9 are placed on the right side of the bed 2. In this case, the operator is positioned on the left side of the bed 2, as well as on the side of the circular table.

Next, an example of the work process according to the present invention will be explained. FIG. 4 is a diagrammatic representation of one of the steps. 8. First, in order to take out the molded work piece from the mold in the previous step, the chuck portion 92 of the piston parr 9 of the take-out device 9 moves forward. Then, it descends, adsorbs, and rises. At this time, main body 1. Neither the circular table 7 nor the supply robot 8 operates.

Subsequently, when the piston parr 91 of the take-out device retreats to its original position, the chuck portion 92 releases the suction and releases the workpiece. When the screw/member 91 retreats, the supply robot 8 also starts operating, and its arm chuck 82 descends to adsorb and lift the workpiece W1 at the supply position, and then advances to the position of the mold 4. After reaching it, descend again, release the suction, and set 14 pieces of gold. At this time, circular table 7
Also set index ji) horizontal J by θ (60 degrees in Figures 1 and 2)
ul liυ, the next workpiece W moves to the supply position and then stops (1-22).Then, the piston par 81 of the supply robot that has completed filling the mold 4 retreats and returns to the original position"?+)l During this time, the main body 1, the circular table 8, and the take-out device 9 do not operate.Then, only the main body 1 is produced.One process is completed by molding the workpiece set in the mold 4. The time for one process is
It is related to the press operation time, but one press operation is 0.6
When it is seconds, set it so that it lasts about 6 seconds.

) l: The invention is as follows: The workpieces placed at a predetermined interval from the lateral force on one side of the bed are set index: 11
water) ■ Rotate once, then move the workpiece w1 to the supply position and stop moving, then move the workpiece w1 to the bed 2.
Supply it to metal No. 1 and 4 of L, and press t.
This method consists of taking out the processed workpiece from the mold by twisting it and then rolling it to the other side.For this purpose, there are two circulars 1-pull 7 and a supply robot 8 necessary for automatically transporting the workpiece to be processed. and the extraction device 9 on both sides of the bed 2.
4. It is placed on both sides, so that at least it does not obstruct the front of the bed. Therefore l! IJ: There is no need to remove the safety device 5 of the manufactured breath machine.

Moreover, even if an operator inserts a part of the body into the die set to inspect or replace the mold, the danger is eliminated and it is safe.

In addition, the circular table 7 rotates horizontally with the set index amount θ, so the index amount can be changed depending on the shape and seed center of the workpiece to be machined. It is also suitable for machining workpieces of different types and shapes.However, as long as the auxiliary table 71 that matches the workpiece shape and scale is prepared, there is no need to replace the entire circular table 7, etc. 1. Good workability and suitable for versatile workpiece machining. 1.
゜Furthermore, the resistance relationship between the circular table 7, the supply robot 8, and the take-out device 9 that opposes them depends on the position of the guide bin 6 of the full-type Dyscent B in either the left or right lateral direction e.
I wonder if it can be converted and installed freely.

Thirty types of die sets and any standard can be used. Therefore, for example, when using a standardized die set called a QDC die set, the guide pin 6 is provided on the back side, so the arrangement as shown in Fig. 1 is not suitable. West 1j fi'? of Circula table, feeding robot and take-out device? By changing as shown in Figure 2.

-The QDC die set attached to the puller main body 1 side only needs to be attached once, and only the mold inside can be quickly replaced, improving drawing efficiency.

The present invention is novel and useful as a method and device for automatically transporting workpieces in a press machine.

61 If you turn off the switch of the device of the present invention, no equipment will be installed.
? Of course, normal work (manual supply and removal) can be carried out without removing the M1, and it is also possible to perform work such as a circular table e, an autoloader 2 or a Verts Wider. - By using a suitable automatic feeder in combination, the entire system becomes an automatic system.

We will expand the range of versatility and implement short-term model changes and
This invention has widened its application to high-mix, low-volume production.
