The specific embodiment

Fig. 1 shows the side view of a shear 1, and the part of its mid frame 2 omits, In order to clearly show that shear. This device has a holding device 3, admits dress at this Be set up metal sheetpile 5 is received in the device 1, metal sheetpile 5 places on the base plate 4. Here, the metal sheetpile can by side guide mechanism and the expansion magnetic patch 6 be clamped in from the heap get Go out the zone of metallic plate. A plurality of mechanisms 7 that take out metallic plate from heap are arranged, its energy above heap Uppermost metallic plate is thrown off from this heap and is lifted in enough will piling, for example by shown in pneumatic Suction cup. This to take out metallic plate from heap be known, so be not further described here. Also show cut cells 12 among Fig. 1, its in the illustrated case by one with a plurality of circular knifes Circle shear to 8 and 9 consists of. This circle shear also is known, does not need here to retouch in detail State. Can find out in the top view of shear shown in Figure 21 how cut cells 12 is Whole width at device extends, and wherein is provided with a plurality of circular knifes in order to shear each metallic plate Right, in order to be cut into bonding jumper. In Fig. 2, the Reference numeral identical with the front represents identical Part shows the top view of a clamping device here, and it can be with the gold that takes out from heap Belong to plate holder and be held in the top of heap, and do not rely on the mechanism that from heap, takes out metallic plate. Fig. 2 for this reason Show four tracks 25,26,27 and 28, they along shear 1 vertically at metal Extend sheetpile receiving positions top. Here track can be arranged on lateral frame 19 and 20, should Lateral frame extends in metal sheetpile holding device both sides perpendicular to device 1. On lateral frame, also There is the unit 7 that from heap, takes out metallic plate to be arranged on the beam 30,31 and 32 that extends longitudinally. These beams can be adjusted along horizontal by dismountable guiding mechanism on lateral frame, so that from The unit 7 that takes out metallic plate in the heap can be matched with the size of metallic plate. At illustrated track 25 In 28 layout, equally on these guiding mechanisms, with the mechanism that from heap, takes out metallic plate Together, so that can adjusting, these tracks adapt to current metallic plate size. Illustrated embodiment In, at track 25 a plurality of magnetic rollers 29 being arranged, it slightly stretches out track downwards. When uppermost metal When plate was upwards taken out 5 from piling by the unit 7 that takes out metallic plate from heap, metallic plate came to magnetic On the roller 29, metallic plate is clamped on the position of heap top thus, is independent of from heap and takes out The mechanism of metallic plate, the latter continues upwards, thereby unclamps metallic plate, so that metallic plate is still by magnetic Roller 29 clampings. Only schematically illustrate three magnetic rollers 29 among Fig. 1, wherein from heap, taken out metallic plate Mechanism also do not arrive final position above it, in this final position, itself and metallic plate 22 No longer contact. Because metallic plate 22 is clamped on the roller 29, just can be by propulsion plant 10 with it Advance seamed edge 11 to shift onto between the circular knife, wherein advance the seamed edge 11 can be along direction of arrow A back and forth Mobile. According to the present invention, be deciding of the desired metallic plate 22 of clipped position accuracy of necessity Position and stabilizing step can be carried out at the clip position of metallic plate 22 on roller 29. Thus cancellation Be located in the prior art heap and

circular knife

8,9 between location bed, this location bed has at least The size of a metallic plate, and not independent according to prior art metallic plate in this location bed Clamping device 25 to 29 and after from heap, taking out, directly place then stable and locate. And Keeper of the present invention is arranged on the top of heap, does not need an independent location bed.

Referring to Fig. 2, keeper with the side lean against on the metallic plate side direction gear roller 13 and 14 with And side direction gear roller 15 and 16. Temporarily be fixed on the gold of heap top by the magnetic roller 29 of clamping device Belong to plate and here for example be pressed onto on roller 15 and 16 by the transverse shifting of roller 13 and 14, thereby Produce the exact position of metallic plate 22. Here, magnetic roller 29 can make metallic plate accordingly mobile, Acted on the power of each metal-sheet edges by roller 13 and 14 to the not impact of bonding jumper edge quality. At positioning stablity after the stage, pushed away by

propulsive mechanism

10,11 by each metallic plates of roller 29 clampings To between 8,9, and catch the shearing slivering by it as known per se to circular knife. Then Next piece metallic plate 23 takes out from piling 5, by taking out the unit 7 of metallic plate by putting from heap To magnetic roller 29 and by its clamping, re-start then stable and positioning step, had good positioning Metallic plate 23 after the vibration of taking out from heap is stable be pushed into circular knife between.

Clamping device can certainly be embodied as other structure that is different from illustrated magnetic device. Example As adopting the plate with lubricious and a plurality of holes, the pneumatic low pressure source of Kong Yuyi links to each other, and makes The metallic plate that must take out from heap can be fixed onboard by negative pressure. Lubricious, for example can Be Te Fulong coating (Teflonbeschichtung) or give plate chromium plating so that each plate still can by Side direction backstop 13 to 16 is located and is shifted onto between the circle shear by

propulsive mechanism

10,11.

By above the metal sheetpile, positioning and stabilizing step, obtained a kind of relatively existing Technology is the shear of compactness obviously, in the prior art, and on metal sheetpile holding device next door Be provided with a very big location and stable bed, thus cutting mechanism and metal sheetpile holding device With very big pitch arrangement. In shear according to the present invention, cut cells 12 can be direct Be arranged in the next door of metal sheetpile holding device, this has reduced the shared ground of shear 1 greatly The face area.

Another aspect of the present invention is described by Fig. 3 to 11, and wherein Fig. 3 has schematically illustrated shearing The top view of device, this shear also have one to hang down with it on cut cells 12 next doors of having stated The straight cut cells 52 of arranging, this cut cells 52 can be to 8 equally with a plurality of circular knifes With 9 circle shear. As can be seen from Figure 3, lie in metallic plate 22 on the cut cells 12 How to form bonding jumper 40 to 43, these bonding jumpers output to illustrated conveying dress along the direction of arrow Put, by this conveying device bonding jumper is transported to cut cells 52 then. Metallic plate is got from heap Go out and stable and location preferably can be carried out as set forth by Fig. 1 and 2 the front like this. Metallic plate 22 also can come before the comfortable cut cells 12 with an independent location and stable bed Traditional shear. This is to being transported to bonding jumper 40 to 43 the conveying dress of cut cells 52 Put working method and substantially do not have impact. This conveying device also can be used in traditional shear.

Can find out that from Fig. 3 and Fig. 4 conveying device has a lot of longerons 45 to 50, its phase Can for example connect into a platform by parts 71 (Fig. 4) mutually. Here conveyer belt linger 45 to 50 operations for example can be cingulums, and it is along the operation of direction shown in the arrow B among Fig. 3, and tool For example common drive unit 60 is arranged, and this drive unit for example can act on cingulum roller 60 ' On, move to cut cells 52 directions with the Continuous Drive cingulum. Below cingulum 56 can Magnet N/S is set in the beam, and this magnet pulls to corresponding cingulum with metallic plate. In beam 45 to 50 Turn round in addition rod 65 to 70, its partial-length in respective beam extends, and is positioned at cut cells 12 The output position, finish a distance before cut cells 52, this distance is equivalent at least The bonding jumper width. The shape of cross section of turning round rod 65 to 70 is a circle of clipping partial arc, As turning round among Fig. 4 shown in the rod 66 to 68.

Turn round excellent 65-70 and preferably have a common positioning drive unit 79, this drive unit is borrowed Help cingulum to be applied to turn round on the cingulum roller 72 on the rod, at bonding jumper 40 to 43 from cut cells 12 Output place, turn round excellent 65-70 and locate as shown in Figure 4 so that metallic plate lean turning round the rod complete On the straightening footpath, this leaning is positioned at the cingulum surface, thereby cingulum 54 to 59 can not connect Touch bonding jumper 40 to 43. Therefore bonding jumper is being turned round the rod reach until ending as shown in Figure 5 Gear 73. When bonding jumper arrives backstop 73, leave cut cells 12 fully, lean against conveying Turning round on the rod of device. This position of bonding jumper shows in the viewgraph of cross-section in Fig. 6. Turn round rod 65 Move on on the conveying device at bonding jumper to 70 and to rotate together along moving direction in the process, such as Fig. 6 Shown in, respectively turn round the relative Fig. 4 of rod and continue rotation, and the bonding jumper that again stops with its diameter leans To conveyer belt. Continue rotation when turning round rod 65 to 70, wherein turn round rod 70 at gold shown in Figure 5 The position that belongs to bar length and backstop 73 is inoperative, and then bonding jumper drops to conveyer belt 54 to 58 On, as shown in Figure 8. This moment, all bonding jumper 40 to 43 passed through together transmission of conveyer belt, from And all bonding jumper is carried towards cut cells 52, as shown in Figure 7. When being positioned at throughput direction When the bonding jumper 40 of front has passed through to turn round the active region of rod, turn round rod and again arrive shown in Figure 10 The position is left from the cingulum lifting at this position bonding jumper, thereby whole conveyings are ended. By No longer be in the active region of turning round rod in bonding jumper 40, therefore continued towards cut cells 52 Carry, and other bonding jumper 41 to 43 is temporarily no longer carried. This moment, bonding jumper 40 was sheared 52 fronts, unit place correct by the registration roller 74 and 75 (Fig. 9) that side direction only is shown among the figure Clipped position, and the conveying cam by under table top, exposing 78 exactly parallel with positioningly with mutually The higher fltting speed of transporting velocity is advanced in the cut cells 52. Be arranged in for example conveyer chain On the relative set of conveying cam 78 here no longer describe in detail because it is known substantially. From As can be known aforementioned, when the clipped position of the width of bonding jumper 40 or first cut cells 12 changes, Conveying device of the present invention does not need readjusting with conveyer. Certainly, remarkable at width During change, require cam 78 is readjusted, rather than whole cingulum conveyer is transferred again Whole. Greatly reduced in this way the downtime when changing shearing or bonding jumper width.

Figure 11 illustrates the another kind of form of implementation of conveying device with schematic side. Bonding jumper from It also is to enter into this conveying device that cut cells 12 comes out. Here, metal whole conveyings how are Conveying cam by on the trailing edge that acts on rearmost bonding jumper figure 11 illustrates Two cams 81 are finished, and are to act on the trailing edge 43 ' of bonding jumper 43 in Fig. 3. These cams are known by the driving of carrier chain basically, so be not described in detail here. If there are not adequate measures to prevent, then bonding jumper whole conveyings in this way usually can be led Cause the mutual slip of bonding jumper. Figure 11 shows and turns

round rod

83 and 84 for this reason, along conveying side To downward-extension on the bonding jumper plane, it is arranged to as shown in the figure, and bonding jumper enters into turns round rod 83 And between 84, so that the bonding jumper slight curvature becomes curve-like. This is rearmost by acting on Finishing cam on the trailing edge of ladder makes bonding jumper common forward towards the direction of cut cells 52 During conveying, bonding jumper reclines reliably each other and avoids in other words relative sliding. Bonding jumper 40 to 43 no longer separate, but carry by the cam 81 of cut cells 52. Therefore cancelled usually Essential conveying cam 78. This moment cam 81 fltting speed greater than shear rate, cam 81 Transporting velocity less than the shear rate of cut cells 52, in order to avoid being positioned at cut cells 52 In bonding jumper and the collision between the bonding jumper to be advanced. Bonding jumper 40 to 43 is only protruding Just separate when wheel speed is slower than the shear rate of cut cells 52. Such as the example of front, at this In the cut cells 52, bonding jumper is cut into metal segments separately. These metal segments are transported, root A kind of preferred application area according to described shear or described conveying device is transported to the box-like frame Round as a ball and welding in the son. As shear, the roll-type that preferred employing can simply be made is sheared single Unit is as shown in WO94/00261.
