[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching machine for punching or punching a product from a material such as an iron plate. The present invention relates to a micro-joint removing device for a punching machine that separates a product and a work by cutting a micro-joint that is a thin connecting portion that connects the two.

[0002]

2. Description of the Related Art Conventionally, a technique relating to a mechanism for removing a microjoint of a punching machine has been known. For example, JP-A-3-138027, JP-A-2-112837, and JP-A-2-17

It is like the technique described in Japanese Patent Publication No.

[0003]

However, in the prior art, there is no technique for automatically removing the microjoint without the hand of an operator and separating the work and the product. Therefore, after the punching or punching by the punching machine, the removal of the product or the unnecessary punched portion from the work is performed by the worker hitting or applying vibration in the next stage. According to the present invention, such a micro-joint removing operation can be automatically separated and removed by a micro-joint removing device arranged at a later stage of the punching machine processing line, and the separation and transfer of the residual frame and the product are not automatically performed.

Next, the operation of the present invention will be described. An iron plate work T is supplied from the work supply storage S to the punching machine M via the positioning table A and the auxiliary table B. Then, in the punching machine M, the product 2 and the hole are punched into a predetermined shape. Then, the product 2 and the remaining frame 4 are sent to the microjoint removing device G in a state where the product 2 and the hole are not dropped while being connected by the microjoint 3. . The vibration mechanism H provided in the microjoint removing device G
, The vibrating frame 9 is vibrated, and the protruding portion 7 having the upper and lower gaps b inside and inside the vibrating frame 9 and having the interval a in front and rear vibrates. The portion of the micro joint is removed from the workpiece T being transported. Then, the product 2 and the remaining frame 4 after the removal are conveyed to the product storage section and the remaining frame storage section by the micro joint removing device G in the next stage.

[0006]

Next, an embodiment will be described. FIG. 1 is a drawing showing a micro joint removing system of a punching machine of the present invention, FIG. 2 is an enlarged side view showing a configuration of a micro joint removing device G, and FIG. 4 is an enlarged side view showing a state in which the micro joint is separated from the work T. FIG. 4 is a plan view of the projection 7 and the vibrating frame 9. FIG. Remaining frame 4
FIG. 6 is a plan view showing a micro joint, and FIG. 7 is a plan view of a punching machine system provided with a micro joint removing device.

The present invention relates to a technique for removing a micro joint 3 connecting a workpiece T and a product 2 generated when the workpiece T is processed by a punching machine M. The punching machine M prepares a plurality of punching tools when the product quantity is not large enough to be pressed, and selects various punching tools by a computer to form various shapes on a work T which is a single iron plate. It is a device for making holes. Therefore,
By exchanging the input tape to be input to the control unit of the punching machine M, a drilling tool can be designated each time to make a round hole or a square hole. However, the drilling tool itself is fixed to the punching machine M, and the work T
Is moved downward to the coordinate position designated in the front, rear, left, and right directions by the transport device 5, and the transport device 5 is disposed below, so that the punched product 2 is dropped downward as in press working. Therefore, it is necessary to remove the microjoint 3 after the transfer from the transfer device 5 to the next step.

Conventionally, the removal of the microjoint 3 has been separated and removed by an operator vibrating the work T or hitting it with a mallet. The present invention provides a micro-joint removing apparatus G that can automate the separation and removing operation of the micro-joint 3. As shown in FIG. 6, the microjoint 3 is often provided at a corner of a punching machine M between the remaining frame 4 and the product 2, and has a narrow width such that the product 2 is not separated. After being sent out from the position 5, the worker is disengaged by applying vibration.

According to the present invention, the product 2
In order to remove the micro joint, a micro joint removing device G as shown in FIGS. 2, 3 and 4 is configured. That is, in the microjoint removing device G, the vibration frames 9a and 9b are vertically arranged, and the vibration mechanism H is disposed on the upper vibration frame 9b. The vibrating mechanism H is driven by a vibrating motor M, and a vibrating weight 6 is provided inside the vibrating mechanism H. The vibrating weight 6 rotates to vibrate. The vibration weight 6
Can be adjusted according to the type of the work T and the product 2, and the number of vibrations and the vibration force of the vibration mechanism H can be changed.

At the lower part of the vibration frames 9a and 9b, vibration supporting springs 8.8 for supporting vibration by the vibration mechanism H are provided, and the vibration mechanism H maintains constant amplitude and frequency. It is configured as follows. Further, inside the excitation frames 9a and 9b, there are provided projection-fixed vertical frames 10a and 10b and projection-fixed horizontal frames 11 and 11 integrated with the excitation frames 9a and 9b. The projecting portion fixing vertical frames 10a and 10b and the projecting portion fixing horizontal frames 11 and 11 are formed in a frame shape, and the work T is inserted between the upper and lower projecting portion fixing vertical frames 10a and 10b by the transfer device. is there.

As shown in FIGS. 2 and 4, a plurality of projecting portions 7 are provided on the projecting portion fixing horizontal frame 11 in such a manner that the projecting portions 7 have a front-to-back space a and a vertical space b. It is arranged so as to protrude from the portion where T passes. As shown in FIG. 3, the projecting portion 7 comes into contact with the portion of the product 2 of the work T which is vibrating up and down in the primary vibration or the secondary, tertiary and quaternary vibrations. On the other hand, the product 2 is extruded, and the product 2 cuts the micro joint 3 and falls.

In such a configuration, the present invention, as shown in FIG. 1, uses a micro-joint removing device G itself for inserting a work T sent out from a punching machine M, as shown in FIG.
The workpiece T, the product 2 and the remaining frame 4 are transported to the next step by the inclined surface. Then, at the stage of transport from the micro-joint removing device G, they are separated vertically. The upper part is a remaining frame inclined conveying device 13 for conveying the remaining frame 4, and the lower part is the product inclined conveying device 1 for the product 2.
4. The work T after being processed by the punching machine M is automatically separated from the product 2 and the remaining frame by the inclination of the micro-joint removing device G and the inclination of the remaining frame tilting and conveying device 13 and the product tilting and conveying device 14. 4 can be separated.

[0013]

As described above, the present invention has the following advantages. First , the worker does not have to remove the product 2 by vibrating the work T or hitting it with a mallet in a state where the product 2 is connected at the micro joint 3 as in the related art. Then, the product 2 and the remaining frame 4 are removed from the transfer device 5 of the punching machine M to the micro-joint removing device G, and the micro-joint removing device G and the rear transfer device are tilted in the next stage. Therefore, the operation of the punching machine M and the micro-joint removing device G can be operated in an unmanned state at night. Second, the upper and lower protruding part fixed horizontal frames 11.1 vibrated by the vibration mechanism H
1 and a protruding portion fixed vertical frame 10a, 10b, a protruding portion 7 having a front and rear space a and an upper and lower space b is protruded, and the protruding portion 7 is primary, secondary, or tertiary. Since the portion of the vibrating workpiece T comes into contact with the product 2, the microjoint 3 can be easily cut from the remaining frame 4.
