Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punch press in which a large number of small products are punched and separated from a work by a punch press, and the separated products are automatically conveyed so that they can be sorted and collected, for example.

[0002]

2. Description of the Related Art Heretofore, various products have been known as products for separating a large number of products from a work and for sorting and collecting the products. First, when a large number of small products are machined in a turret punch press as a punch press, for example, a small amount of contour processing of each small product is left, and a so-called micro joint with the original large size work is left. After unloading the large size work pieces with all small products connected from the Talesi Punch Press, manually tap each small product to separate it from the original large size work piece, and then The small products are sorted according to product type and collected.

Secondly, after the small products separated by the punch and the micro joint are sucked by a vacuum pad or a magnet, the small products are sorted and stacked on a stacking pallet by an unloader.

Thirdly, a contour cutting punch is provided in the turret punch press, and each small product is separated from the large-sized work by the contour cutting punch, and then the turret punch press is carried out on the rear side table. It is carried out by rollers. The small products carried out are transferred and positioned by a transfer means capable of positioning the products in two orthogonal directions, and then the small products are sorted into a collection pallet by type by an unloader.

[0005]

By the way, in the multi-cavity processing by the above-mentioned first means of the related art, it takes manpower to separate each small product from a large-sized work, and each small product is separated. After that, there was a problem that it took another manpower to sort each product type.

Next, the second means has a problem that the vacuum pad cannot be used when the product has a hole, and that the suction by the magnet cannot be applied to the non-ferrous material.

Further, in the third means, after each small product is separated from the large size work by the contour cutting punch, it is carried out by the carry-out roller provided on the rear side table. There was a problem that the waiting time was long because the next punching work could not be done while in. Moreover, the transfer means in the third means is
The residual material left after cutting off small products, the so-called sun dump, was not considered.

In view of the above problems, an object of the present invention is to reduce the waiting time of punch press work regardless of whether the work material is ferrous or non-ferrous and whether or not there is a hole in the product without requiring manpower. It is to provide a punch press capable of treating residual material.

[0009]

In order to achieve the above object, the present invention provides a punching portion for punching a work by cooperation of an upper die and a lower die, and an appropriate number of punches from the work. A separation processing part for performing separation processing that separates individual products is provided, a slide table that is slidable is provided adjacent to the separation processing part, and a conveying means that conveys the product or the residual material is provided directly below the slide table. To form a punch press.

In the punch press, a transfer means for positioning the product in two directions and transferring the product is provided adjacent to the end side of the transfer means in the transfer direction, and the transfer device has an end side in the transfer direction. It is desirable to provide an accumulation pallet for accumulating products.

Further, in the punch press, it is preferable that a residual material box for accommodating the residual material is provided adjacent to a side orthogonal to the transfer direction of the transfer means.

[0012]

By adopting the punch press of the present invention, after punching the work in the punching part for punching the work in cooperation with the upper die and the lower die, the work is performed in the cutting part. A suitable number of products punched from the product are cut off. In the state where this separation processing has been performed, the slide table is slid in the conveying direction by the length of the relevant product to be opened, so that the product falls onto the conveying means immediately below. Then, immediately after the slide table is closed and returned to the original state, the cutting processing of the next product is started in the cutting processing section.

The product dropped on the conveying means is conveyed in the conveying direction and moved to the adjacent conveying means. The product transferred on the transfer means is transferred in the transfer direction and also in the direction orthogonal to the transfer direction. Then, the products are accumulated on the accumulation pallet.

Further, the residual material after the various products are separated from the work is placed on the above-mentioned transfer means through the same operation as the above-described product transfer and transfer operation, and then, in the transfer direction. After being moved to the leftover material box provided adjacent to the orthogonal side, it is stored and accumulated.

By appropriately operating 1 and the sub-cutting punch 43, the waiting time for punching work can be significantly shortened, which has the effect of improving work efficiency.

On the other hand, the product P dropped on the belt conveyer 47 is conveyed backward and is carried out to the roller conveyer in the cross feed table 23 described later. However, small products that cannot be sorted and stacked on a stacking pallet described later are dropped from the driven pulley 51 to the small product box 53 by tilting the belt conveyor 47 backward around the drive pulley 49 (FIG. 2 and FIG. Figure 5 (c)
See).

Next, the cross feed table (transfer means) 23 will be described in detail with reference to FIGS. 1, 2, and 3.
First, as described above, the LM guide 27 and the rack 31 are provided on the upper surface and the side surface of the upper frame 25 to guide and support the slide table 21 in the front-rear direction, as shown in FIG.

With the above structure, when the drive motor 65 is rotated, the drive belt 63 is rotated between the idlers 61, so that the plurality of pipe rollers 59 are simultaneously rotated. Therefore, the product P transferred from the belt conveyor 47 to the roller conveyor 67 is transferred from the front to the rear and reaches the rear end of the roller conveyor 67, but before that, the stopper cylinder 7
When the No. 1 piston rod is projected, the stopper base 75 swings from the rearwardly inclined position to the horizontal position, so that the stopper plate 69 largely swings and projects onto the transfer line of the roller conveyor 67. Then, the product P is held at its rear end and positioned in the front-rear direction. After this positioning, by stopping the drive motor 65 and retracting the piston rod of the stopper cylinder 71, the stopper plate 69 can be retracted under the transfer line of the roller conveyor 67 while largely turning. The above-described mechanism for projecting and retracting the stopper plate 69 allows the stopper plate 69 to be largely moved up and down even if the stroke of the stopper cylinder 71 is short, so that it can be compactly housed in a desired space and interfere with the operation of other components. There is nothing to do.

Further, the cross feed table 23 is provided with an intermediate height frame 83, and the intermediate height frame 83 is provided with an LM guide 85 extending in the left-right direction. A scraper frame 87 guided and supported by the LM guide 85 is provided so as to be movable in the left and right directions. In order to move the scraper frame 87 to the left and right, a rack 89 is provided extending in the left and right direction at the lower center of the scraper frame 87 as shown in FIGS. 1 and 2, and the rack 89 and the intermediate height are arranged.

The rod end pin and the trunnion are interlockingly connected. Therefore, the tilt table 109 is swingably provided to the left. When the tilt table 109 swings to the left, the left half portion 119 interferes with the roller conveyor 101, so a plurality of notches 121 are provided at the left end.
The notch 121 is not only for avoiding the interference with the roller conveyor 101, but also for the purpose of making the left half portion 119 serve as a scraper for scraping off the residual material S as described later. Furthermore, the tilt table 1
On the lower left side of 09, a residual material box 123 is provided as shown in FIGS.

The operation of the cross feed table (transfer means) 23 having the above structure will be described. Belt conveyor 4
The product P carried into the roller conveyor 67 from 7 is transported backward by the rotation of the pipe roller 59, and is positioned in the front-rear direction by the stopper plate 69 at the rear end. While the product P is being transferred rearward by the roller conveyor 67, the pusher bar 97 is moved leftward by the appropriate operation of the moving motor 91, and the left-right positioning is also performed. The positioning in the left-right direction is performed in order to facilitate the sorting and stacking of the products P on the stacking pallet, which will be described later, and to increase the efficiency.

Next, the work W which has finished punching the product P,
That is, a case where the residual material S is carried into the roller conveyor 67 will be described. First, after the stopper plate 69 is set in the protruding state, the residual material S is positioned on the roller conveyor 67 in the front-rear direction. Further, when the pusher bar 97 is fully moved from right to left in a state where the right half of the tilt table 109 is horizontal, the residual material S gets over the tilt table 109 to the left and the roller conveyor 101.
Fall on top. Then, since the roller conveyor 101 is inclined to the left, the residual material S comes into contact with the abutting frame 125 provided at the left end and stops.

When the piston rod of the tilt cylinder 117 is projected, the tilt table 109 swings to the left, so that the lower part of the left half portion 119 is cut into the roller conveyor 101 by the notch 121. .. At this time, when the scraper frame 87 is moved rightward together with the roller conveyor 101 by operating the moving motor 91, the residual material S is left on the left half portion 1 of the tilt table 109.
While being squeezed by 19 and rolling on the roller conveyor 101 and being pressed by the left end against the frame 125,
It is dropped and accumulated in the lower residual material box 123.

An accumulation pallet 127 is provided adjacent to the rear end of the cross feed table 23. This stacking pallet 127 is a lifter 12 provided on the floor surface.
It is placed on a lifting table 9 (not shown). Further, a known unloader 131 is provided above the stacking pallet 127. The unloader 131 is provided with a guide rail 133 extending in the front-rear direction and supported on the floor surface, and a rack 135 is provided on the side surface of the guide rail 133.

A clamper 143 is provided on the slider 137 so as to be movable left and right. The height of the clamper 143 is provided so as to match the height of the transfer line of the roller conveyor 67.

With the above structure, the product P positioned at the rear end of the roller conveyor 67 in the front-rear direction and the left-right direction is gripped by the clamper 143 which is previously positioned in the left-right direction. Then, by appropriately operating the carry-out motor 139, the product P is moved to the upper side where the corresponding product P is accumulated on the accumulating pallet 127, and then the clamper 143 is released, so that the product P is accumulated on the accumulating pallet 127. Sorted and collected automatically. When releasing the clamper 143 and dropping the product P to the corresponding stacking place, the lifter 129 is appropriately operated so as not to increase the drop.

By adopting the punch press of this embodiment as described above, first, the slide table 21 is opened by the length of the product P at the final stage of separating the product P from the work W (plate 55). As a result, the punching waiting time is shortened and the working efficiency is improved.

Since the products P transferred onto the cross feed table 23 are also moved and positioned in the direction orthogonal to the transfer direction, the products P are automatically and efficiently placed on the accumulating pallet 127 for each product P. It is effective in that work efficiency is improved by sorting and accumulating.

Further, the residual material S is also used for the cross feed table 2.
After being moved to the upper side, the leftover material box 1 adjacent to the left side
Since it is automatically accumulated in 23, there is an effect that work efficiency is improved.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in other modes by making appropriate changes.

[0042]

As can be understood from the above description of the embodiments, according to the present invention, the product cut from the work in the cutting processing section is opened in the conveying direction by the length of the corresponding product. Immediately after being dropped from the gap of the slide table to the conveyance means, the slide table is closed and the cutting punch starts to operate for cutting the next product, so the waiting time of the punch press is shortened and the work efficiency is improved. There is an effect of doing.

The products transferred onto the conveying means are also moved and positioned in the direction orthogonal to the transfer direction, so that the products are automatically and efficiently sorted on the accumulating pallet, so that the work efficiency is improved. It has the effect of improving.

Further, after the residual material is also transferred onto the transfer means,
There is an effect that the work efficiency is improved because the remaining material boxes are automatically accommodated and accumulated in the residual material box provided adjacent to the side.
