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 out of a work by a punch press and separated, and the separated products are automatically conveyed, for example, to be sorted and collected.

[0002]

2. Description of the Related Art Conventionally, various products have been known for separating and collecting a large number of products from a workpiece. First, when a large number of small products are to be machined from a large-sized work using a turret punch press as a punch press, for example, the original large-sized work and a so-called microjoint are left with a small amount of contour processing for each small product. After removing the large-sized work with all small products connected from the Taleshi punch press, lightly tap each small product by hand to separate it from the original large-size work, and then manually Each small product is sorted by product type and accumulated.

[0003] Secondly, small products separated from the micro-joint and punched are suctioned by a vacuum pad or a magnet, and then sorted and collected on an accumulation pallet by an unloader.

Third, a turret punch press is provided with a contour cutting punch, and each small product is separated from a large-sized work by the contour cutting punch, and then is carried out on a rear side table in the turret punch press. Rolled out. The transported small products are transported and positioned by transport means capable of positioning the products in two orthogonal directions, and then each of the small products is sorted by type into an integrated pallet by an unloader.

[0005]

By the way, in the above-described multi-cavity machining by the first means, the work of separating each small product from a large-sized work requires labor and also separates each small product. After that, there is a problem that it takes time and labor to sort by product type.

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

Further, in the third means, each small product is separated from a large-sized work by a contour cutting punch, and then is carried out by a carry-out roller provided on a rear side table. , There is a problem that the next punching operation cannot be performed and the waiting time increases. Moreover, the transfer means in the third means includes:
The remaining material after the small product was cut off, the so-called Sun dump, was not considered.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to reduce the waiting time of a punch press work regardless of whether a work material is ferrous or non-ferrous, regardless of the presence or absence of a hole in a product, without requiring any manpower. An object of the present invention 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 section for punching a work by cooperation of an upper die and a lower die, and an appropriate number of punches from the work. A separating section for performing a separating process for separating individual products is provided, a slidable slide table is provided adjacent to the separating section, and a conveying means for conveying the product or the remaining material is provided immediately below the slide table. To form a punch press.

[0010] In the punch press, a transfer means for positioning the product in two directions and transferring the product is provided adjacent to the end of the transfer means in the transfer direction. It is desirable to provide an accumulation pallet for accumulating products on the pallet.

Further, it is preferable that the punch press is provided with a remnant material box for storing the remnant material adjacent to a side orthogonal to the transfer direction of the transfer means.

[0012]

By using the punch press of the present invention, the work is punched in the punching section for punching the work in cooperation with the upper mold and the lower mold, and then the work is cut in the separating section. The cutting process is performed on an appropriate number of products punched from the product. In the state where the separation process is performed, the slide table is slid in the transport direction by a length corresponding to the product to be opened, whereby the product falls onto the transport means immediately below. Then, as soon as the slide table is closed and returned to the original state, the next product separation process is started in the separation processing section.

The product that has fallen on the transport means is transported in the transport direction and is transferred to an adjacent transport means. The product transferred on the transfer means is transferred in the transfer direction and also in a direction orthogonal to the transfer direction. The products are then accumulated on an accumulation pallet.

Further, the remaining material after the various products are cut off from the work is placed on the transfer means via the same operation as the above-mentioned product transfer and transfer operation, and then the transfer direction and After being moved onto the remaining material box provided adjacent to the orthogonal side, it is stored and collected.

On the other hand, the product P that has fallen on the belt conveyor 47 is conveyed backward and is carried out to a roller conveyor in the cross feed table 23 described later. However, small products that cannot be sorted and collected on a stacking pallet, which will be described later, are dropped from the driven pulley 51 to the small product box 53 by the belt conveyor 47 being tilted rearward about the drive pulley 49 (see FIG. 2 and FIG. 2). FIG. 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, the LM guide 27 and the rack 31 are provided on the upper surface and the side surface of the upper frame 25, respectively, and the slide table 21 is guided and supported in the front-rear direction as described above, as shown in FIG. An inner upper frame 57 extends in the front-rear direction inside the upper frame 25, and a plurality of pipe rollers 59 are rotatably supported inside the inner upper frame 57. A plurality of idlers 61 are provided below the pipe rollers 59 as shown in FIG. 2, and press the drive belt 63 from below to transmit rotation to the pipe rollers 59. The drive belt 63 is rotated by a motor pulley linked to a drive motor 65. The plurality of pipe rollers 59 constitute a roller conveyor 67, and the transfer line on the upper surface is provided so as to coincide with the transfer line on the upper surface of the belt conveyor 47 in a horizontal state.

At the rear end of the roller conveyor 67, FIG.
As shown in FIG. 7, a stopper plate 69 extending in the left-right direction is provided by a stopper cylinder 71 so as to be able to protrude and retract from the transfer line. More specifically, as shown in FIG. 2, an appropriate number of pin brackets 73 indirectly fixedly supported on the inner upper frame 57 are provided side by side in the left-right direction.
A stopper base 75 is provided on the pin bracket 73 so as to be swingable so as to be inclined from the horizontal to the rear via a pin. A pin bracket 77 is provided below the stopper base 75.

With the above configuration, when the drive motor 65 is rotated, the drive belt 63 rotates between the idlers 61, so that the plurality of pipe rollers 59 rotate simultaneously. Therefore, the product P transferred from the belt conveyor 47 to the roller conveyor 67 is transported 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 first piston rod is made to protrude, the stopper base 75 swings from the position inclined backward to the horizontal position, so that the stopper plate 69 protrudes above the transfer line of the roller conveyor 67 while largely turning. The product P is positioned in the front-rear direction with the rear end held down. After this positioning, if the drive motor 65 is stopped and the piston rod of the stopper cylinder 71 is retracted, the stopper plate 69 can be immersed below the transfer line of the roller conveyor 67 while largely turning. The mechanism for projecting and retracting the stopper plate 69 described above can move the stopper plate 69 up and down greatly even if the stroke of the stopper cylinder 71 is short, so that the stopper plate 69 can be compactly stored 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 movably in the left-right direction. In order to move the scraper frame 87 left and right, a rack 89 is provided extending left and right 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 provided. This is achieved by meshing with a pinion 93 interlockingly connected to a drive shaft of a moving motor 91 which is a servomotor supported and fixed to the frame 83. Further, a plurality of stands 95 are located on the right side of the scraper frame 87.
And a pusher bar 97 is provided thereon so as to be movable in the left-right direction together with the scraper frame 87. The pusher bar 97 is a member having a channel-shaped cross section extending in the front-rear direction as shown in FIG. 3, and has an upper end projecting from the transfer surface of the pipe roller 59 as shown in FIG. As shown, a plurality of notches 99 are provided on the lower surface so as not to interfere with the pipe roller 59. Therefore, the pusher bar 59 is connected to the pipe roller 5.
9 can be moved in the left-right direction without interfering with the function of No. 9.

Further, on the scraper frame 87, a plurality of roller conveyors 101 extend left and right, and
As shown in FIG. 3, the taper is inclined leftward (in FIG. 3, inclined rightward). This roller conveyor 101
Is provided on a scraper frame 87 with a channel section (tooth shape) opened upward and inclined leftward on a scraper frame 87, and a large number of rollers 105 are arranged on the conveyor base 103 in the left-right direction. It is provided rotatably supported. The plurality of roller conveyors 101
As shown in FIG. 2, they are provided on the scraper frame 87 so as to be arranged back and forth, and are appropriately connected at right and left ends by connecting plates 107.

On the other hand, a tilt table 109 extending back and forth is provided on the left upper frame 25 so as to be swingable via a pin 111 supported by the upper frame 25 as shown in FIGS. . The tilt table 109
Normally, the right half is provided horizontally at a height corresponding to the transfer surface of the roller conveyor 67, while the left half is provided to be inclined leftward in a U-shape. The tilt table 1
An appropriate number of pin brackets 113 are provided below the right half of the horizontal section 09. A rod end trunnion type tilt cylinder 117 is provided between the pin bracket 113 and the pin bracket 115 supported by the upper frame. It is linked and connected by a rod end pin and a trunnion. Therefore, the tilt table 109 is provided to be able to swing to the left. When the tilt table 109 swings to the left, the left half portion 119 interferes with the roller conveyor 101, so that a plurality of notches 121 are provided at the left end.
The notch 121 has a purpose not only to avoid interference with the roller conveyor 101, but also to cause the left half portion 119 to function as a scraper for scraping off the remaining material S as described later. In addition, tilt table 1
In the lower left part of 09, a remaining material box 123 is provided as shown in FIGS.

The operation of the cross-feed table (transfer means) 23 having the above configuration will be described. Belt conveyor 4
The product P conveyed from 7 to the roller conveyor 67 is transported rearward 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 transported rearward by the roller conveyor 67, the pusher bar 97 is moved to the left by the operation of the moving motor 91 as appropriate, so that the positioning in the left-right direction is performed. The positioning in the left-right direction is performed in order to easily sort and accumulate the products P on an accumulating pallet, as described later, and to improve efficiency.

Next, the work W which has finished punching the product P,
That is, a case where the residual material S is carried in onto the roller conveyor 67 will be described. First, after the stopper plate 69 is set in the protruding state, the remaining material S is positioned on the roller conveyor 67 in the front-rear direction. 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 remaining material S passes over the tilt table 109 to the left and the roller conveyor 101.
Fall on. Then, since the roller conveyor 101 is inclined to the left, the remaining material S abuts against the butting frame 125 provided at the left end and stops.

When the piston rod of the tilt cylinder 117 is protruded, the tilt table 109 swings to the left, so that the lower half 119 is cut into the roller conveyor 101 by the notch 121. . At this time, when the scraper frame 87 is moved to the right together with the roller conveyor 101 by operating the movement motor 91, the remaining material S becomes the left half 1 of the tilt table 109.
19, while rolling on the roller conveyor 101 with the left end struck by the frame 125,
It falls into the lower remaining material box 123 and is collected.

An accumulation pallet 127 is provided adjacent to the rear end of the cross feed table 23. This stacking pallet 127 is mounted on the lifter 12 provided on the floor surface.
9 on a lifting table (not shown). Further, a known unloader 131 is provided above the accumulation pallet 127. The unloader 131 is provided with a guide rail 133 extending back and forth and supported on the floor surface, and a rack 135 is provided on a side surface of the guide rail 133.
Is provided. The slider 137 is provided so as to be movable in the front-rear direction while being guided and supported by the guide rail 133.
The movement of the slider 137 is performed when the pinion 141 interlocked with the unloading motor 139 meshes with the rack 135. Further, 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 configuration, the product P positioned at the rear end of the roller conveyor 67 in the front-rear and left-right directions is gripped by the clampers 143 positioned in the left-right direction in advance. By appropriately operating the unloading motor 139, the product P is moved upward where the corresponding product P is accumulated on the accumulation pallet 127, and then the product P is moved onto the accumulation pallet 127 by releasing the clamper 143. Automatically sorted and collected. When the clamper 143 is released and the product P is dropped to the corresponding collecting location, the lifter 129 is appropriately operated so that the head does not increase.

As described above, by employing the punch press of this embodiment, the slide table 21 is first opened by the length of the product P at the last stage of separating the product P from the work W (the plate 55). As a result, it is possible to reduce the waiting time for punching and improve the working efficiency.

The products P transferred to the cross feed table 23 are also moved and positioned in a direction orthogonal to the transfer direction, so that the products P are automatically and efficiently placed on the stacking pallet 127 for each product P. There is an effect that the work efficiency is improved by being sorted and accumulated.

Further, the remaining material S is also a cross feed table 2
3 After being moved on, left box 1 adjacent to the left
Since they are automatically accumulated in the storage unit 23, there is an effect that work efficiency is improved.

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

[0042]

As can be understood from the above description of the embodiment, according to the present invention, the product separated from the work in the separation processing section is opened in the transport direction by the length of the corresponding product. Immediately after the slide table is dropped from the gap of the slide table to the transporting means, the slide table is closed and the separation punch starts to operate for separating 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 transporting means are also moved and positioned in a direction orthogonal to the transfer direction, so that the products are automatically and efficiently sorted on the stacking pallet for each product. There is an effect of improving.

Further, after the remaining material is also transferred to the transfer means,
Since it is automatically stored and accumulated in the remaining material box provided adjacent to the side, there is an effect that the working efficiency is improved.
