Description

[Detailed description of the invention] a. Industrial application field The present invention relates to a device for separating micro-joint parts, and more specifically, the present invention relates to a device for separating micro-joint parts, and more specifically, to remove a large-sized piece after nibbling while leaving an appropriate number of micro-joint parts on the contour line of the shape. A double-opening table is installed to horizontally support the fixed-length plate material at the position where it is carried out from the punching machine.
A gripping device and a stretching device are provided for approaching and gripping opposite edges of the regular-sized plate material on the table and expanding and holding the regular-sized plate material with tension around the center line of the table, and the double-door table is A reversible conveyor is installed almost horizontally in the open lower part, and moves while rotating away from the upper surface of the fixed-length plate material that is gripped and stretched by the table frame member equipped with the gripping device and the stretching device. This invention relates to a micro-joint separation device equipped with a rotary hammer that hammers almost the entire top surface.

b. Prior Art First, as shown in Fig. 3, the micro joint part 1 is
Explain.

For example, when cutting a plurality of medium-sized blanks 5 from a regular-sized plate material 3 such as 90 x 180 (cm ² ) using a turret punching machine, etc., without using a rectangular mold, Overtaking is performed using a combination mold consisting of a small square punch and a corresponding die.

In other words, since the blank 5 punched with a rectangular die is inconveniently limited to specific dimensions, continuous punching (punching) with a small square punch or the like is used to adapt it to high-mix, low-volume production.

However, in general, the scraps from punching work are
The medium-sized blank 5 that passes through the center hole of the die and is ejected from below the die, but remains on the work table of the punching machine and becomes an obstacle to the movement and positioning of the regular-length plate material 3 in the subsequent operation.

Therefore, the punching process is completed by providing a micro-joint part 1 in which the standard-sized plate material 3 remains as it is at the step part of the overtaking part or the part where the mold to be used changes, and then the standard-sized plate material 3 (in this case (It's just a piece of dregs with holes, and it's called a skeleton.)
It is necessary to separate the product from the product.

Conventionally, the work of separating the microjoint portion 1 described above has been mostly done manually, and there has been no power-driven method that is compact and inexpensive.

c. Problems to be Solved by the Invention The disadvantages of the conventional devices described above, which are complicated and expensive, are solved by the device described below.

d Means for solving the problem The present invention has the above-mentioned micro joint part 1,
At the initial stage of transporting the regular-sized plates 3 together, a device was installed that spread them out horizontally above the belt conveyor and struck them with a power-driven rotary hammer to separate them.

e Effect: With the device of the present invention, a medium-sized blank product produced by the punching process can be automatically separated from the skeleton and transported out separately.

f Embodiment The separating device 7 for the micro-joint part 1, which is an embodiment of the present invention shown in FIGS. This was carried out. [Related to unpublished application (Jet Application No. 59-039087) of the same applicant] The depositing device 11 is equipped with double-opening roller stands 15, 15 (see FIG. 8) above the carry-out cart 13; Centering gripping devices 17, 17 are provided. Fluid pressure cylinder 1 shown in FIGS. 1 and 2
9, a chain 21, and sprockets 23, 23, the double-opening roller stands 15, 15 move toward and away from each other around the center line 25.

Furthermore, the centering gripping devices 17, 17 symmetrically approach and move away from the center line 25 by means of a servo motor 27, sprockets 29, 29, and chain 31.

In the apparatus according to the embodiment of the present invention illustrated in FIGS. 1 and 2, a lower pressure type fixed length plate material gripping claw device 35 such as a fluid pressure cylinder 33 is provided on the center line 25 side of the centering gripping device 17.

Also, a roller stand 15 and a centering gripping device 17
Rack plates 39 are provided on the upper and lower sides of the frame body 37 shown in FIG.

The above-mentioned cutting device 7 for the medium-sized blank 5 is as follows:
A pinion gear 43 is fixed to both ends of a round rod-shaped shaft 41 parallel to the center line 25 described above. Furthermore, the shaft 41 is driven by an electric motor 49 such as a servo motor attached to a motor cart 47 that is guided by rails 45 on the frame body 37 and can move left and right, and moves across the entire width of the standard-sized board 3 while rotating. do.

As shown in FIGS. 4, 5 and 6, the shaft 41
A suitable number of striking elements 51 are swingably provided on the outer periphery of the cylinder via links 53, and as shown in FIG. The hammering action is performed every 90 degree rotation.

As shown in FIG. 2, when the roller stand 15 under the centering gripping device 17 of the present invention is opened to the left and right, the fixed-length plate 3 is moved to the roller stand 1 as shown in FIG.
A belt conveyor 55 is provided that moves in a direction perpendicular to the direction in which the paper is transported.

This belt conveyor 55 is a pantograph mechanism 5
7 on a trolley 59, and can be moved up and down while maintaining a horizontal position, and the above-mentioned hammering operation is performed after approaching the fixed-length plate 3 as shown in FIG.

The belt conveyor 61 shown on the right side of the belt conveyor 55 in FIGS. 2 and 4 carries out the medium-sized blanks 5 in the front and back directions of the paper in FIG. It is.

After all of the medium-sized blanks 5 that have been subjected to the punching process are carried out, the grip of the gripping claw device 35 by the fluid pressure cylinder 33 is released, and the fixed-sized plate material 3 (the part excluding the medium-sized blank 5 corresponds to a skeleton) is placed on the belt conveyor 55.

If the belt conveyor 55 is reversed, the standard length plate material 3
The skeleton part will be transported to the scrap chute 65 on the left side of FIG.

As is clear from the detailed description above, in order to operate the apparatus according to the embodiment of the present invention, first a plurality of medium-sized blanks were punched out from a standard-sized plate material, leaving micro joints. Transfer an object to a roller table in a horizontal position without applying impact.

Next, the opposing sides of the processed regular-sized plate material on the roller stand are gripped by a centering gripping device, spread out across the center and held almost horizontally, and the roller stand is opened from the bottom and moved away, allowing the belt conveyor to approach.

At this time, the electric motor is started and the shaft of the cutting device is rotated while moving the full width of the standard length plate to apply a hammering action to separate the micro joints.

The separated medium-sized blanks are conveyed in a different direction by a belt conveyor and transported to a storage box, and then the skeleton portion of the regular-sized board is released from its grip and sent in a different direction by the belt conveyor directly below. Proceed to Scrapshoot.

g. Effects of the invention In the apparatus according to the embodiment of the invention described in detail above, a conventional large-sized blank stacking apparatus is modified to include a new centering gripping apparatus for horizontally rolling out fixed-length plates, and an unloading belt conveyor is installed on the underside of the centering gripping apparatus. This is a device that uses a rotary hammer to separate the punched portion from the regular-length plate material while the two are brought close to each other.

Therefore, there is no manual operation required, and the device is neither complicated nor costly, resulting in safe labor savings.

It is also clear that the design can be easily changed without departing from the technical idea of the present invention.
