Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a ball conveyor of a cutting press device that transports the cut blanks out of the cutting press device from a cutting press device that cuts blanks from a strip-shaped plate material. It is.

(Prior art) In recent years, blanking lines that cut out raw materials (blanks) to become products from strip-shaped plates are equipped with blanking dies equipped with cutting blades in order to improve processing efficiency. A cutting press device that shears the material into a predetermined shape and size is often used. In such a cutting press device, when attempting to obtain various types of trapezoidal, rectangular, etc. blanks with different dimensions from a strip-shaped plate material, the position of the blank die is repositioned for each loft.

Conventionally, in order to carry out the blanks cut out from such a cutting press device, wheel conveyors of appropriate sizes are arranged before and after the slidable blank die to supply the strip material, The blanks that had been cut out were being carried out.

(Problems to be Solved by the Invention) However, in the ball conveyor of this type of cutting press device, when setting the blank die,
First, pull out the wheel conveyor that gets in the way before and after the blank die that will be slid.

This is because once the die set is completed, a wheel conveyor of a size that matches the space before and after the blank die that has been slid is reinserted.

It is difficult to completely eliminate complicated operations that require manual labor, making it difficult to apply automatic control such as numerical control using a computer to the cutting press device.

The present invention has been made with attention to these points, and by making the width of the conveyor before and after the slidable blank die expandable and contractible in the bed axis direction, it can be easily adapted to computer-based numerical control, etc. The purpose of the present invention is to provide a cutting press device that provides a cutting press.

(Means for solving the problem) Therefore, in the present invention, blank dies equipped with cutting blades are mounted on a bed, and at least one of the blank dies is slidable in the axial direction of the bed. A cutting press machine cuts out a blank of a predetermined shape and size from a band-shaped plate material using the cutting blade of each blank die, and a conveyor for transporting the cut blank to the outside of the cutting press machine is equipped with a pair of arms. A pantograph mechanism is formed by connecting a plurality of pairs of arms rotatably connected at the center thereof, the ends of each arm being rotatably connected to each other, and forming a pantograph mechanism. A plurality of balls are rotatably supported and arranged on the upper surface of a predetermined arm, and the pantograph mechanism is attached to the front and rear of the sliding direction of the slidable blank die, respectively. .

(Function) With the ball conveyor of the cutting press device of the present invention configured as described above, when trying to obtain various blanks with different dimensions from a strip-shaped plate material, even if the blank die is repositioned, the pantograph Due to the action of the mechanism, the width of the ball conveyor changes steplessly in the axial direction of the bed as the blank die slides, so it is necessary to replace the conveyors before and after the slidable blank die each time the die is set. Manual work is completely eliminated, and it becomes easy to apply numerical control by computer to the cutting press device.

(Example) Next, an example of implementation of the present invention will be described with reference to the drawings. In the drawings, 11 is a bed of a cutting press device, and 13 is a plate guide portion for guiding a strip-shaped plate. 1
Reference numeral 5.17 indicates a blank die to which a cutting blade (not shown) is attached, and the rotation of the blank dies 15 and 17 is controlled by a first driving source not shown in the drawings. The bed 11 is slidably controlled in the axial direction indicated by the arrow A in FIG. 1 by the drive source 19 of No. 2. 21 are the blank dies 15 and 17 on the bed 11;
This is a blank extrusion mechanism disposed between the blank die 15 and the blank die 17, and moves so as to be always located in the center between the blank die 15 and the blank die 17 in accordance with the sliding movement of the blank die 15.

23 is a first conveyor, 25 is a second conveyor, and 27 is a third conveyor, each of which is constituted by a pantograph mechanism as shown in FIG.

As shown in FIG. 3, the arms 29 and 31 or 33 and 35 are made into a pair and are rotatably pivoted at their central portions to form an arm pair 37 or 39. A large number of such arm pairs 37 and 39 are prepared and arranged alternately, and the arms 29 and 33 or 31 and 35 are rotatably pivoted at their respective ends. As a result, the arm pairs 37 and 39 are alternately and continuously connected to form a telescopic pantograph mechanism 41. A plurality of balls 43 are disposed on the upper surface of the arm 29 disposed above the pantograph mechanism 41 and are supported so as to be able to rotate once, forming a ball conveyor. Also.

The balls 43 are also rotatably arranged on the upper surfaces of the pivot points of the arms 29, 31, 33, and 35, and the upper ends of each ball 43 are at the same level.

In the first conveyor 23 having such a structure, one end of the pantograph mechanism is attached to the plate material guide section 13, and the other end is attached to the slidable blank die 15, respectively. Also,
The second conveyor 25 similarly carries blank dies 15 and 17.
The third conveyor 27 is installed between the blank die 15 and the blank extrusion mechanism 21 and between the blank extrusion mechanism 21 and the blank die 17.

Further, 45 is a fourth conveyor attached to the blank die 17, and 47 is a fifth conveyor extending from this fourth conveyor 45. Both conveyors do not have an expandable structure.

According to the ball conveyor of the cutting press device according to the present invention configured as described above, the strip-shaped plate material is sent out by a predetermined dimension from the plate material guide section 13 via the first conveyor 23, and the blank die 15 and the blank die 17 Then, the blanks are cut into blanks having predetermined shapes and dimensions. Among these blanks, those cut by the blank die 17 fall onto the fourth conveyor 45 and the fifth conveyor 47, and are carried out to the front of the cutting press device along the inclination thereof. Further, the blanks cut by the blank dies 15 and 17 fall onto the second conveyor 25 and the third conveyor 27, and are carried out to the side of the cutting press device by the action of the blank extrusion mechanism 21. .

After cutting out the blanks of the lot, the angles of the blank dies 15 and 17 and the position of the blank die 15 are reset in accordance with the dimensions of the blanks to be cut in the next loft. At this time, the first conveyor 23 and the second conveyor 23
．． The third conveyor 25° 27 expands and contracts according to the positions of the blank die 15 and the blank extrusion mechanism 21 by the action of the pantograph mechanism 41 thereof. Therefore, the space between the plate material guide section 13 and the blank die 15, and the space between the blank dies 15 and 17 is automatically filled with each of the conveyors 23 or 25, 27. Each of these conveyors 23,
Since the arms 25 and 27 have a rotatably supported ball 43, even if the angles of the arms 29 to 35 change, there is no problem in conveying the blank.

Although the present invention has been described in detail according to the embodiment shown in FIG. 4, the present invention is not limited thereto. The ends may be rotatably connected using the metal fittings 45 without overlapping. In this case, by providing the notches 47 in the arms 29 and 31, the pantograph mechanism 41 can be retracted until the arms 29 and 31 are in perfect contact.

Furthermore, since the upper surfaces of arm 29 and arm 33 are on the same level, ball 43 can be placed on the upper surface of arm 33 in the same way as on the upper surface of arm 29.

In addition, it is not necessary to arrange the balls 43 on the upper surfaces of all the arms on the upper side of the pantograph mechanism 41, and it may be arranged only on the upper surfaces of the minimum number of arms as long as it does not hinder the conveyance of blanks. .

(Effects of the Invention) The present invention is constructed as described above, and the conveyors before and after the slidable blank die are configured to be extendable and retractable by the action of the pantograph mechanism, so that the blank die can be slid when resetting the die. However, since each of the above expands and contracts according to the position of the blank die, etc., there is no need to replace the conveyors before and after the slidable blank die each time the die is set, completely eliminating manual work. Not only can the present invention be easily applied to cutting presses that are automatically controlled by computer numerical control, etc., which is an excellent effect.
