These conveyers only allow limited transportation stroke, and it directly depends on the length of rotatable arms or guide rod respectively.
European patent EP 0621093B1 (M ü ller-Weingarten) and EP0600254B1 (Schuler) and U.S. Patent application US2003/84701A1 (Komatsu) mention the conveyer that punch line is used, wherein cross bar extends between the transportation balladeur train in the forcing press both sides, and cross bar has the anchor clamps that are used for holding workpiece.Described transportation balladeur train can independently move on the horizontal support rail that the transporting direction that is parallel to conveyer extends.Wherein the balladeur train of EP0621093B1 comprises the upright driving mechanism that is used to rise and reduce cross bar, and EP0600254B1 and US2003/84701A1 disclose vertically movably supporting rail.
In principle, the transportation stroke of these conveyers permissions is only limited by the length of supporting rail.Yet the structure of these conveyers is very complicated, and must be in the horizontal direction in transportation and/or the quality of numerous elements of moving of vertical direction be very big.Correspondingly, the speed of realization and efficient just are restricted.
EP0309430A1 (Volvo) relates to a kind of conveyer that is used for punch line, and this conveyer designs in so a kind of mode, and the ground space between stamping machine is fully left a blank out.Comprise in the disclosed embodiment that one has the center bearing bracket of two upright guide rails.The height adjusting slider is fit to move along these guide rails with being set up.These slide plates have some arm configurations that stretch out from guide rail, and these arms are at they end bearing lateral adjustments slide plates separately.These slide plates carry a vertical rail, and it can tilt about its longitudinal axis and vertical axis.And this vertical rail can rotate around its longitudinal axis.One coaster is set to move along track on this track, coaster carries one can be around the clamping device of a plurality of rotations.In order to transmit, from stamping machine, shifted out down the auxiliary of a feed appliance by a workpiece of the clamping device clamping of conveyer.At first, clamping device is around the vertical axes half-twist, and then workpiece is transmitted along track, and clamping device is rotated about a horizontal axis 180 ° simultaneously and locatees perpendicular to direction of transfer.At last, clamping device is by half-twist in such a way again, and workpiece can be transferred into another feed appliance that this workpiece is moved into next stamping machine.
This device is allowed in transportation and workpiece to be reorientated and directed.Yet it is not suitable for heavy and/or big workpiece and does not allow quick transportation.
Summary of the invention
An object of the present invention is, a kind of conveyer that starts this area of mentioning that belongs to is provided, promptly simple in structure, allow long transportation stroke and be used for the conveyer of transmitting workpiece effectively apace.
According to the present invention, the parts that are used for supporting traverse comprise rotating mechanism, are used for around the horizontal pivot axis line rotating beam perpendicular to transporting direction, also comprise rotationally the anchor clamps of motion, are used for compensating at least the variation of the workpiece location that the rotation because of crossbeam produces.And, this conveyer comprises that one second crossbeam and is used to support the parts of this second crossbeam, these parts comprise a rotating mechanism, be used for rotating second crossbeam around the horizontal pivot axis line perpendicular to transporting direction, second crossbeam and these parts are arranged on stamping machine second side across stamping machine first side.The bar of one cross bar form extends across stamping machine and is connected on two crossbeams.
Basically, the vertical displacement that is connected to the bar of crossbeam is that rotational action by overall beam realizes.This action allows to reduce apace and rise bar, and crossbeam serves as the effect of lever.The quality of the element that will be moved in transportation obtains reducing.Both there is no need mobile vertically overall beam and also there is no need to adopt extremely heavy balladeur train, this balladeur train comprises the upright driving mechanism that is used to rise or fall bar, and wherein said heavy balladeur train need move along crossbeam.In principle, the transportation stroke of conveyer of the present invention is not restricted; It is generally determined by the length of crossbeam.In addition, simple in structure according to conveyer of the present invention, so conveyer low cost of manufacture.
Although rotational action is arranged,, extends on crossbeam always being arranged essentially parallel to the transporting direction of conveyer.According to transportation range and required rise degree, angle of rotation with respect to the horizontal plane mostly is most 3-15 °.This enough is used for holding workpiece, transports out of first stop with its rise with it.The horizontal movement of workpiece is realized along moving of crossbeam by bar basically.
Each station that workpiece transports between it can be the forcing press station that comprises the mould of two cooperations, and other station of multiple position press, such as initial dispatch station, be arranged in middle station, perhaps last delivery heap or the conveyer of transporting Forming Workpiece placed between the forcing press station.Conveyer for example can be made up of the robot or transmitting workpiece to the shuttle of debarkation stop of general conveyer belt, stack shaping workpiece.
Anchor clamps can freely be selected from prior art, and this depends on the workpiece that will transport.Anchor clamps can be specifically by attracting, magnetic force, form fit or traction come holding workpiece, as the attraction instrument, the groove of Magnetic tools or those and workpiece, the instrument of opening or projection cooperation.
Usually, the bar of clamping device flatly and perpendicular to transporting direction extends.Yet bar all is possible in any direction, and this allows in each forcing press station clamping and unloads workpiece.
The rotational action of anchor clamps is preferably rotated around its longitudinal axis by bar and is realized.In the ordinary circumstance of the horizon bar that extends perpendicular to transporting direction, the longitudinal axis of bar is parallel to the rotating shaft of crossbeam.Therefore, by the longitudinal axis around it bar is rotated, anchor clamps are rotated, so the workpiece location that is caused by the rotation of crossbeam changes and can accurately be compensated.Yet the rotational action of anchor clamps is not limited to the compensation location to be changed, and the transportation from first stop to second station, the location of workpiece can change as required, for example adjusts the location for following modular form and structure according to second station.
Generally, the parts of supporting traverse are disposed in the side of forcing press, are preferably located in the center between the first stop and second station.These parts can be do not need to support or be connected near the station, particularly be connected to the vertical support of forcing press, perhaps be connected to the base of forcing press in the punch line.
The cross bar that use is fixing at two ends can reduce to act on the torque of crossbeam, and therefore heavier load can use lighter parts to transmit.
Preferably, rotating mechanism forms like this, then rotating shaft intersect with the vertical plane that comprises crossbeam, perhaps on crossbeam, below or pass crossbeam, especially near the mid portion of crossbeam.In this manner, and compare from the situation of forcing press side and this hand-deliver fork, crossbeam is formed a rocking bar, and at it in the moving of crossbeam, bar passes the point of safes in its path, if the point that can vertically not move when promptly crossbeam does not rotate.Therefore, bar is can be at its two end points places in path raised and fall, and allows to pick up or put down workpiece in the position near beam-end.
In addition, the simple structure that this layout obtains has minimum torque, and therefore makes the power minimum on the element that acts on the clamping crossbeam.When the vertical plane of close crossbeam mid portion was passed in rotating shaft, this layout was correct especially, so the compensation of quality realizes optimization, and the distribution of the power on the element of clamping crossbeam is the most symmetrical.In addition, rotate if crossbeam leans around the rotating shaft of nearly its center arrangement, the end points of crossbeam is implemented vertical substantially motion.
Advantageously, conveyer comprises that two stride across the forcing press beam arranged, and bar is to stride across forcing press cross bar that extend, that be connected to two crossbeams.Cross bar is fixed at two ends, and the torque that acts on the crossbeam can be minimum, in being to use the heavier load of lighter carry elements.Yet, the invention is not restricted to have the conveyer of cross bar, but expand to conveyer with the cantilever that is connected to crossbeam, wherein these arms are connected with the anchor clamps of holding workpiece.In this case, the crossbeam that has cantilever can be arranged in the both sides of forcing press, and perhaps conveyer is one-sided, and promptly the cantilever of the transmitting workpiece that is useful on engages with forcing press from the same side.
Preferably, it is supported that at least one is used to support the parts of one of two crossbeams, so in order to adjust two distances between the crossbeam, can reorientate in the direction perpendicular to transporting direction.This allows the length of cross bar to adapt to the width of forcing press like a cork, and the width of this forcing press depends on the size of the mould of use again.One of parts with respect to another such as being transportable on rail, perhaps the same cross bar of clamping, to stride across two parts that forcing press arranges be that symmetry moves.By adopting the cross bar of minimum length, the quality that is moved element is all minimum with the power that acts on the crossbeam, allows the greater flexibility of conveyor system and operation faster.
Selectively, these parts are installed in the fixed position, and the length of the cross bar that adopts is predetermined length, allow its Breadth Maximum that has of transportation can be by the mach workpiece of pressure.
Preferentially, described parts also comprise the elevating mechanism that is used at the vertical direction moving beam.This allows crossbeam is risen or drop to the position that maintenance work can not carried out by crossbeam with hindering, for example, so can change the mould of forcing press.In addition, conveyer can promptly adapt to differing formed forcing press and/or mould.Though in the press operation process vertical motion of clamping bar basically (preferentially whole) realize by the rotational action of crossbeam, in transportation, if consider quicker operational example, can adopt by vertically moving that elevating mechanism carries out as under situation with special finishing die auxiliaryly.
Selectively, conveyer can form like this, so for maintenance work, crossbeam can be removed in another way, for example pass through it to be folded or arrive vertical position for about 90 ° by rotating beam, so mould can be removed, be inserted between the crossbeam.
Advantageously, rotating mechanism comprises two axles (spindle) that are connected to crossbeam, and in order to rotate and preferably vertical moving beam, described axle can be operated independently.By mobile axle independently, particularly by the reverse rotation axle, two isolated strong points of crossbeam are moved, and allow rotating beam.At least one connector between axle and crossbeam comprises a compensation mechanism, is used to compensate because the variable in distance between the strong point that the independent operation of axle causes.Preferably, two axle layouts parallel to each other and extend at vertical direction.Correspondingly, the strong point is general and against being arranged on the crossbeam.In this case,, crossbeam is vertically moved, so two strong points as one man rise or fall if two axles of simultaneously operating are rotated in the same way.In preferable case, compensation mechanism advantageously comprises horizontal guide groove, is used for a connector between axle and the crossbeam.Preferably, axle and connector form the ball-screw parts.
Exist the scheme that plurality of optional is selected for rotating mechanism.For example, crossbeam can be installed to single horizontal rotating shaft, and this axle is connected above-mentioned parts, limits the pivot axis of crossbeam.In this case, by the driven guide rod of linearity (perhaps a plurality of guide rod) that any some place at the distance pivot axis is pivotally connected to crossbeam, can control rotational action.Another may scheme be directly to control rotational action by the rotating drive mechanism that is bonded on rotating shaft.
Advantageously, crossbeam comprises two connectors vertically arranging along crossbeam, preferably symmetric arrangement and close crossbeam center.Each connector cooperates with an axle.Arrange vertically that along crossbeam connector allows axle directly is bonded on the strong point of beam, crossbeam strides across axle herein; There is no need to use certain arm or similar middleware.Therefore, make the designs simplification of rotating mechanism (the particularly connector between the strong point of axle and crossbeam), and reduced the space (particularly in direction) that needs across forcing press.By a strong point or two strong points of the crossbeam that moderately is shifted, make it possible to the quick rotation crossbeam near crossbeam center arrangement connector.The optimum weight compensation of two exterior parts of crossbeam is provided with respect to the symmetric arrangement at crossbeam center.
Selectively, axle is connected to the terminal part of crossbeam, for example by the arm of the strong point that connects axle and crossbeam.
Preferably, crossbeam comprises the telescopic drive mechanism of the slip that is used for bar.This allows the vertical fast moving of bar along crossbeam, there is no need to increase the relative acceleration between the adjacent element that is moved.Therefore, the acceleration of the bar that obtains can increase, and causes the improvement in performance of conveyer.In addition, by adopting telescopic drive mechanism, the stroke of conveyer can increase, and there is no need the overall beam that extends.This has been avoided the conflict between the adjacent beams and has reduced the weight of beam parts.
Advantageously, telescopic drive mechanism can be by the brace summer that is connected to rotating mechanism, second balladeur train that is installed to first balladeur train of brace summer and is installed to first balladeur train slidably slidably forms.This makes the simple in structure, in light weight of crossbeam, and makes that at the same time the guiding of bar of holding workpiece is stable.
Selectively, can adopt other known telescopic drive mechanism for crossbeam.
Preferably, have the situation of long transportation route especially, linear guides in the middle of between the brace summer and first balladeur train, arranging, described thus guide rail can be removable with respect to the brace summer and first balladeur train.Advantageously, middle linear guides designs by this way and arranges, promptly it is with respect to the unique decision of relative position of brace summer by first balladeur train with respect to the position of the brace summer and first balladeur train.This can be by providing ormal traction power to realize between middle linear guides and the brace summer and first balladeur train.Therefore, do not need the driving mechanism that adds, be used for the additional travel of telescopic drive mechanism.By linear guides in the middle of adopting, can reduce the relative velocity of linear moving member, promptly first balladeur train can be divided into respect to the relative velocity of brace summer, and middle linear guides is with respect to first speed of brace summer and first balladeur train second speed with respect to middle linear guides.Therefore, the mechanical stress that is caused by high speed and acceleration can obtain relaxing.In addition, can allow on brace summer, to support reliably first balladeur train by linearly moving middle linear guides, even under the situation of the length that reduces brace summer.By the weight that reduces length and reduce brace summer thus, the power and the moment that act on rotating mechanism reduce.In addition, because the littler length of (linearity is fixed) brace summer, the conflict between beam and the adjacent forcing press station can be avoided.
Preferably, be useful on is along beam carriage release lever and the driving mechanism that is used for cant beam, fixes with regard to the moving longitudinally of beam with regard to bar.Therefore, have to be minimized by the quality of the element of fast moving.In addition, compare with the situation of the mobile driving mechanism that needs haulage chain etc., the power supply of fixed drive mechanism is simpler.Compare with the situation in the conveyer field with balladeur train, described balladeur train comprises the driving mechanism that is used for vertical carriage release lever, is used to rotate longitudinal beam and realizes that the driving mechanism that vertically moves of bar is arranged to bar irrelevant along moving of crossbeam.Most preferably, described driving mechanism is completely fixed, as two axles that are connected to parts and are connected to crossbeam.Be used for also fixing with regard to the action of beam with regard to bar along the driving mechanism of beam carriage release lever.For example, it can be connected to the core of crossbeam and comprise the transmission mechanism that is connected to balladeur train, and such as driving shaft, balladeur train moves relative to beam.The little driving mechanism that rotatablely moves that only is useful on anchor clamps need move and share the quality of the element of fast moving with bar.
Selectively, described being used for for example comprises linear induction motor between the balladeur train that is arranged in longitudinal beam and supporting rod along the driving mechanism of beam carriage release lever.Can make up different driving mechanisms, for example first of telescopic drive mechanism section can be driven by fixed motor by rack and pinion drive, and other section is by linear electric motor.
Be used for conveyor system, comprise the conveyer of a plurality of continuous layouts at punch line or multimode stamping machine transmitting workpiece.Generally, for forcing press, need N+1 conveyer: N-1 the conveyer between the forcing press station, a conveyer and a conveyer that is used for taking away workpiece that transports workpiece to the first forcing press station from last forcing press station with N station.
The situation that need make the workpiece upset from a station to the next stop, as recurrent in the double-acting forcing press, two continuous conveyers are preferably arranged like this, so workpiece can be transferred second conveyer to from first conveyer, thus, make the workpiece upset, promptly rotate about 180 °.Therefore, do not need to be used to the to overturn special-purpose intermediate station of workpiece.
A kind of forcing press particularly in punch line or the multimode stamping machine from first stop to method near the second station transmitting workpiece of first stop, employing is connected to the bar of crossbeam, crossbeam is arranged in a side of forcing press, is parallel to transporting direction and extends, and this method comprises the steps:
A) bar is placed on the top that is in the workpiece in the first stop;
B), bar is reduced by coming rotating beam around horizontal pivot axis line perpendicular to transporting direction;
C) by being connected to the anchor clamps holding workpiece of described bar;
D) by crossbeam is rotated around described pivot axis bar is risen;
E) by along the described bar of vertically moving of described beam, make workpiece be transported to second station;
F) by crossbeam is rotated around described pivot axis, bar is placed on the transfer position; With
G) unload workpiece from anchor clamps.
Especially, by being forcing press at second station, the middle placement stood, and place work piece in individual final conveying heap or the conveyer arrives and transfers the position.
Some steps can be implemented simultaneously, promptly rise and/or fall and transport step a) and b), d) and e), and/or e) and f),, take place simultaneously at least in part promptly along described bar of vertically moving of beam and rotation.Therefore, can quicken transportation.Workpiece is being placed on second station promptly after forcing press, before described bar left working space between the upper and lower mould, punching operation was promptly fallen patrix and can be begun.In order to make this operating sequence the best that can implement and make punch line or multimode stamping machine, the path of bar unloaded or load can be by correspondingly the rotation and the lateral movement of control lever customize.Consider further optimization, at first in the punch line that forcing press station itself can asynchronously be operated, the action that belongs to the bar at different stations can be controlled independently.
Preferably, described method also comprises the step of mobile anchor clamps rotationally, and the location that is used for compensating at least the workpiece that the rotation because of crossbeam causes changes.The spinning movement of anchor clamps is not limited to compensate the variation of location, and the location of workpiece can change the transportation from first stop to second station as required, for example in order to make the location adapt to the structure of the counterdie at second station.
If second station is the another conveyer that is used for further transmitting workpiece, this conveyer comprises second anchor clamps, described method can comprise the another step that moves the anchor clamps of two conveyers rotationally, so the workpiece by the anchor clamps clamping of first conveyer is placed on delivery position, it can directly be transferred to second anchor clamps of another conveyer herein.Therefore, workpiece is reversed.Before transporting it into the next stop, just in the situation of double-acting forcing press, often workpiece need be overturn.Adopt method of the present invention to save special-purpose intermediate station.
Other useful embodiment and combination of features come from following detailed description and all claims.

Fig. 3-the 6th, other different views of conveyer: Fig. 3-5 are respectively from the forcing press outside and inboard and along the upright view of the axis of forcing press; Fig. 6 is the vertical view of conveyer.Support component 100 comprises by three level boards: two parallel vertical posts 101,102 that substrate 103, intermediate plate 104 and top board 105 keep at a certain distance away and fix.Vertical column 101,102 has I type cross section (see figure 2), its main axis that extends perpendicular to forcing press.Substrate 103 serves as the effect of platform, so strengthen the stability of support component 100.Top board 105 supports two driving machines 106,107, and each driving machine is connected to an end of the vertical axle 108,109 that is arranged in support component 100 inboards.The other end of axle 108,109 is by the bearing support that is fixed on intermediate plate 104.In addition, a vertical column 102 has vertical guide slot 110 in its same inboard, and this guide groove is parallel to respective mandrels 109.
What be connected to support component 100 inboards is crossbeam 300.For this reason, crossbeam 300 comprise along crossbeam 300 vertically, symmetrically and near its two connectors 301,302 of center arrangement.One of cooperating in axles 108,109 of each connector 301,302 forms the ball-screw parts.For this reason, connector 301 comprises vertical internal thread, interacts with the external screw thread of vertical axle 108,109 by the ball bearing that forms between screw thread.Vertical internal thread its master's (vertically) axis relatively is rotatably fixing, still can rotate around trunnion axis relative to crossbeam 300.
By at a direction or another one direction mandrel 108,109, connector 301,302 is raised respectively or fall.Therefore, by operating axle 108,109 independently, can set the gradient of crossbeam 300; By operating two axles 108,109 simultaneously, can not change the rise of gradient ground or reduce crossbeam 300 so that it has same rotary speed and direction of rotation.These two kinds of motions are promptly rotated and are risen or fall, and can superpose by correspondingly selecting rotatablely moving of axle 108,109.
Along with the gradient increase of crossbeam 300, because the relative crossbeam 300 of the distance between the strong point on the axle 108,109 increases, the distance of connector 301,302 has to adjust simultaneously.For this reason, a connector 301 comprises compensation mechanism 303, its by be parallel to crossbeam 300 longitudinally two rails form, can slide mobile at this rail upper connector 301.Another connector 302 is fixed on crossbeam 300.
Crossbeam 300 comprises brace summer 310, second balladeur train 330 of a telescopic drive mechanism 320 and an end (see figure 2) that is connected cross bar 500.Brace summer 310 is made up of the hollow section part 311 that is connected connector 301,302.Two parallel rails 312,313 are arranged on the inner surface of hollow section part 311, along the longitudinal extension of brace summer 310.
Telescopic drive mechanism 320 is arranged in the inboard and channeling conduct on these rails 312,313 of brace summer 310.Driving mechanism 320 comprise 321, two of first balladeur train that have a roller at two ends be with 322,323 on the balladeur train around first balladeur train 321, vertically be directed along it.First balladeur train 321 main extends half of brace summer 310 length of being longer than crossbeam 300 a little.At its inner surface, first balladeur train 321 comprises a pair of parallel rail 324,325 that is used for sliding guidance second balladeur train 330.
On the one hand, be with 322,323 to be fixed on second balladeur train 330, on the other hand, these bands are fixed on the core of brace summer 310.Because be with the relative motion of 322,323 relative first balladeur trains 321, in case drive first balladeur train 321 along brace summer 310 with given speed, just in same direction with identical speed drive second balladeur train 330 of relative first balladeur train 321.Because the stack of motion, the relative brace summer 310 of the speed of second balladeur train 330 that obtains is the twice of the speed of about first balladeur train 321.
Fig. 2-6 is illustrated in second balladeur train 330 of left-most position.First balladeur train 321 and second the balladeur train 330 relatively vertically brace summer 310 of crossbeam 300 are easily seen.The length of crossbeam 300 is that 5-6 rice is corresponding with the distance at the adjacent forcing press station that deducts telescopic drive mechanism 320 unnecessary length.This makes locatees adjacent conveyer in punch line or multimode stamping machine, so two conveyers can reach same centre position, workpiece is put down or be picked herein, and does not disturb between the crossbeam of conveyer.That is, the projection of first balladeur train 321 passes through two spaces between the adjacent beams in the process of picking up or putting down of workpiece.Otherwise brace summer 310 is reserved enough spaces and is used to make crossbeam to rotate and is used for cross bar with adjacent conveyer and be placed in the space between the crossbeam.
Driving mechanism 304 is connected the core rear side of crossbeam 300.It passes through the space of reserving the ample clearance between the vertical column 101,102, then driving mechanism 304 neither can conflict also not with the rotation of crossbeam 300 can with it rise or fall and conflict.This driving mechanism is cooperated with the guide rail that is connected first balladeur train 321, so first balladeur train 321 can move relative to the brace summer 310 of crossbeam 300.
On second balladeur train 330, arrange the driving mechanism 331 that is used for rotary bar 500.If it is connected to cross bar 500 by gear reduction, this driving mechanism 331 can be very little.Cross bar 500 is made up of cancellate framework 501, and described framework has a plurality of anchor clamps 502 of the workpiece that clamping will transport that are used for as the attraction instrument.On the one hand, rotating horizontal pole 500 is used to compensate because the location of the cross bar 500 that the rotation of crossbeam 300 brings changes.On the other hand, the location of cross bar 500 can optimization, is used for picking up work piece, and the location of the workpiece of transportation can adapt to the destination of workpiece, such as the structure of the mould of delivery heap or destination forcing press.Cross bar 500 can automatically unload from second balladeur train 330, is replaced such as the cross bar with another kind of anchor clamps by another.The replacement of anchor clamps preferably occur on the mobile brace summer or on the balladeur train that separates.
The power and the anchor clamps 502 that are used for the driving mechanism 331 of rotating horizontal pole 500 are carried by haulage chain as the required compressed air of attraction instrument, and this haulage chain comprises cable and airduct, is arranged in the top of the brace summer 310 of crossbeam 300.For the sake of clarity, haulage chain does not draw in the drawings.
Fig. 7 represents the detail drawing of the telescopic drive mechanism of conveyer.Telescopic drive mechanism 320 is parts of crossbeam 300, and crossbeam is connected axle 108 by connector 301, and the lower end of axle 108 is supported by the intermediate plate 104 of support component 100.Connector 301 comprises the swivel plate that has gantry post, is used for respect to regulating the location of the connector 301 that is connected to crossbeam 300 with the vertical screw thread of axle 108 coupling.Connector 301 also comprises compensation mechanism 303, and this mechanism is made up of with the respective guide slots (guidance) that is connected to connector 301 the horizontal rail of the brace summer 310 that is connected to crossbeam 300.Compensation mechanism 303 allows the variable range of compensation between the strong point of the connector on the axle.
And crossbeam 300 comprises the support 305 of cooperating with the vertical guide slot 110 that is fixed to one of vertical column 101.Support the part of 305 burden tilt torque and the holding power that burden produces between crossbeam 300 and support component 100, so removed the burden of axle.
Driving mechanism 304 is connected to the rear side of hollow section part 311 of the brace summer 310 of crossbeam 300.Power transmission shaft stretches out from the front surface of driving mechanism 304, its axle be level and perpendicular to the main extension of crossbeam 300.Power transmission shaft passes through hollow section part 311 by the opening of rear surface.Be arranged in the pinion 307 in hollow section part 311 the place aheads,, be connected the front end of power transmission shaft by another opening in the front surface of hollow section part 311.Pinion 307 cooperates with the tooth bar 308 that extends along first balladeur train 321 and be connected to this balladeur train.Therefore, by operation driving mechanism 304, drive first balladeur train 321 and move along the main extension of the brace summer 310 of crossbeam 300.
Guide groove 326,327 by being connected first balladeur train 321 cooperates with the rail of brace summer 310 312,313, and first balladeur train 321 is slidably mounted in brace summer 310.Guide groove 332,333 by being connected second balladeur train 330 and the rail of first balladeur train 321 324,325 cooperate, and second balladeur train 330 of clamping cross bar 500 is slidably mounted in first balladeur train 321.
Be with 322,323 cores that are fixed on brace summer 310 around what first balladeur train 321 was directed, near the place of arranging driving mechanism 304.In addition, be with 322,323 to be fixed to second balladeur train 330.The guiding of the roller by being arranged in two ends is with 322,323 can move freely by relative first balladeur train 321.
Fig. 8 A-F is the illustrative of method of the present invention.Fig. 8 A is illustrated in the cross bar 500 of right-hand position; Crossbeam 300 is tilted, so the center of cross bar 500 relative crossbeams 300 reduces.Normally, required maximum rise scope is about 30cm or still less, and the allowable angle of inclination that this means relative horizontal plane is about 6 ° or still less.In obliquity, the picking up of workpiece 2 that is positioned at first stop 10 is to provide negative pressure to realize by the attraction instrument to cross bar 500.In case workpiece 2 is picked, the right side axle 107 of operation support component 100 is rotated crossbeam 300, so it arrives horizontal level.Therefore, workpiece 2 rises from first stop 10.In rotating process,, just begin the horizontal movement of second balladeur train 330 of clamping cross bar 500 in case workpiece 2 discharges from first stop 10.This allows from the mobile apace cross bar 500 of the working space between the upper die and lower die, and the process efficiency maximization that punch line is implemented.In the rise process,, cross bar 500 is rotated in order to compensate the relative positioning of cross bar 500 relative second balladeur trains 330.Therefore, the location of workpiece 2 keeps constant.
In the situation shown in Fig. 8 B, in case after crossbeam 300 arrived horizontal level, because moving of the rotation of crossbeam 300 and second balladeur train 330 is synchronous, cross bar 500 moved towards the center of crossbeam 300.Next, the motion of second balladeur train 330 continues.Need point out that because the telescopic arrangement of balladeur train, second balladeur train 330 is with the speed motion of twice first balladeur train 321.Fig. 8 C represents the center of conveyer.
Fig. 8 D situation before the rotational motion of crossbeam 300 of representing to be about to begin.Second balladeur train 330 and cross bar 500 also do not arrive its left-most position, and are subjected to the influence of left side axle 106, continue to move to the left side in the rotational action process of crossbeam 300.Fig. 8 E represents to arrive the situation of left-most position, and its middle cross beam 300 inclinations, so workpiece 2 can break away from cross bar 500 and be placed on second station 20.Once more, in falling process, for the relative positioning that compensates cross bar 500 relative second balladeur trains 330 changes, cross bar 500 is rotated, so the maintenance of the location of workpiece 2 is constant.
Along with the disengaging of workpiece 2, by rotating beam 300, will rise empty cross bar 500, and in case may, cross bar 500 just begins central horizontal towards crossbeam 300 toward swivel motion, so arrive the state shown in Fig. 8 F.Workpiece 2 one is ready to transportation, just then carries out from first stop 10 to second stations 20 the next circulation technology of transmitting workpiece 2 again.
Need point out, in described technical process, crossbeam 300 itself do as a whole neither fallen not raised yet.Rotational action by crossbeam 300 influences falling of cross bar 500 specially and rises.Need not rise under the situation of overall beam 300, the rise scope also can further increase: this is to realize once unload the horizontal level that rotating beam 300 is returned to it from first stop by horizontal level and workpiece that rotating beam in the rise process 300 surpasses it.
Yet, if implement maintenance work or if mold exchange more, just need be with crossbeam 300 rises.In addition, according to the geometry of punch line and conveyer, if except rotational motion, also replenish moving both vertically of overall beam 300, the motion of cross bar 500 can be controlled more neatly.Need point out that each conveyer of punch line (comprising two support components in illustrated embodiment, two crossbeams and cross bar) can be operated separately.This makes the technological process of punch line further optimize.
Fig. 9 be in order to overturn workpiece two adjacent conveyers 52,52 ' between transfer the schematic diagram of workpiece.In order to realize transferring workpiece, the cross bar 500 of holding workpiece is rotated about 90 °, so workpiece 2 is by clamping erectly.Subsequently, with two adjacent conveyers 52,52 ' second balladeur train 330,330 ' move to adjacent outermost end position, this depends on the width of workpiece 2.Simultaneously, second conveyer 52 ' cross bar 500 ' rotation, so its anchor clamps are towards the anchor clamps of another cross bar 500 of first conveyer 52.In this position, can realize transferring: at short notice, both sides are holding workpiece 2 all just, breaks away from workpiece 2 and removes cross bar 500 up to first conveyer 52.By rotate second conveyer 52 ' cross bar 500 ', workpiece 2 is located once more, so it is guided into forcing press station.Yet because the action of transfer as shown in Figure 9, the location of workpiece 2 is reversed.
Figure 10 is the perspective view according to conveyer of the present invention, has relocatable support component.Conveyer 52a is the conveyer shown in the corresponding diagram 2-7 52 in fact.Yet the support component 100a that is used for supporting traverse 300,400 of conveyer 52a, 200a is modified, so in that they can relocate perpendicular to the direction of transporting direction.For this reason, support component 100a, 200a is by extend through two parallel rails 601,602 supports that forcing press extends below press machine lower die.Rail 601,602 extends end to end from a support component 100a to another support component 200a, forms rail 600, support component 100a, and 200a can relocate along this rail.
Two support component 100a, 200a are included in spool or the roller that cooperates with rail 601,602 on their the substrate 103a bottom side.In addition, they comprise and are used for fixed support part 100a on rail 601,602, the fixture of the position of 200a.If conveyer 52a is used at the width of a pair of mould forcing press transmitting workpiece littler than cross bar 500 maximum lengths, take off long cross bar 500, break away from support component 100a, the fixture of 200a, and reorientate support component 100a, 200a, so can use shorter cross bar, its length adapts to the width of mould.At last, the support component 100a that reorientates, 200a are fixed to rail 601,602 at their reposition once more.
Illustrate with the conveyer of the present invention with rotatable crossbeam though be used to reorientate the layout of support component, the application part of this layout is not limited to such conveyer.It also can expand to other conveyor system, this system has crosses over the interchangeable cross bar that forcing press extends, forcing press in its both sides by supporting units support, what for example, those were known has balladeur train, rotatable arms that is supported on the horizontal rail or the conveyor system that is used for the guide-bar mechanism of clamping cross bar.
Under a stable condition,, promptly more close or to have only a support component further from forcing press be relocatable just enough if in direction perpendicular to transporting direction.These rails can separate, rather than continuous.Except rail and spool or roller, can adopt the known support thing of other permission linear movement.For the operation that makes this layout simpler, described two support components and/or fixture can for example link together by chain drive mechanism each other, then parts reorientate cause the corresponding symmetry of another parts reorientate and/or the fixing of two parts takes place simultaneously.By correspondingly controlling the driving mechanism that rail transversely moves support component, the distance adjustment between the support component can manually or automatically be implemented.
Figure 11 A, B represent the vertical view according to two positions of another embodiment of conveyer of the present invention, and having with additional middle linear guides is the telescopic drive mechanism of feature.Usually, the structure of the described conveyer of structure corresponding diagram 1-7 of conveyer.Yet, to compare with the foregoing description, the characteristics of another embodiment of this conveyer 52b are that the brace summer 310b length of crossbeam 300b reduces.The length of brace summer 310b is the length of the corresponding first balladeur train 321b of cardinal principle just in time.In order to allow the secure support of the first balladeur train 321b at brace summer 310b, linear guides 340b in the middle of between the brace summer 310b and the first balladeur train 321b, being provided with.Middle linear guides 340b is slidably to move for its two adjacent elements.Its length approximates half of the first balladeur train 321b length greatly.
Together with middle linear guides 340b, the 320b of telescopic drive mechanism, it has the structure shown in Fig. 5-7 basically, form three sections telescopic drive mechanisms, promptly, the relative velocity that can be connected with the relative brace summer 310b of the second balladeur train 330b (it does not move horizontally along forcing press) of cross bar is divided into first speed of the relative brace summer 310b of middle linear guides 340b, the second speed of the middle relatively linear guides 340b of the first balladeur train 321b and the third speed of the relative first balladeur train 321b of the second balladeur train 330b.Be used to provide the better power except having two drive unit 304.1b and 304.2b,, promptly adopt rack-and-pinion to drive, start the telescopic drive 320b of mechanism with mode the same in the foregoing description.
Figure 11 A has described the situation that the second balladeur train 330b is in the center.At this state, the first balladeur train 321b and middle linear guides 340b be also in their center, promptly with respect to the center symmetry of crossbeam 300b.Because the length of brace summer 310b reduces, conveyer 52b also reduces (contrast Fig. 8 c) along the span of forcing press, and this makes that the processing of workpiece in adjacent forcing press is no problem.
What Figure 11 B described is the situation that the relative crossbeam 300b of the second balladeur train 330b is in the outermost end position.Almost half of the first balladeur train 321b exceeded the brace summer 310b of crossbeam 300b in the vertical.Middle linear guides 340b moves towards the corresponding end of brace summer 310b, and is still supporting the first balladeur train 321b along its whole length, partly comprises two drive unit 304.1b, the part that 304.2b cooperates with the first balladeur train 321b.Therefore, guarantee the firm support of the first balladeur train 321b, particularly at drive unit 304.1b, 304.2b applies the zone of moment and power to the first balladeur train 321b.The distance of the second balladeur train 330b is divided into, middle linear guides 340b, and the first balladeur train 321b and the second balladeur train 330b are 1:1:2 with respect to the relative distance of their adjacent external components, promptly the absolute distance of these elements is 1:2:4.
Figure 12 represents the detail drawing of first embodiment of the middle linear guides that adds.Once more, be connected to the rotatablely moving of driving mechanism 304.1b of brace summer 310b rear side, by pinion 307b be delivered to the first balladeur train 321b cooperating of tooth bar 308b, wherein pinion is connected to the driving shaft of driving mechanism 304.1b, and tooth bar 308b is fixed on the first balladeur train 321b and along its extension.Linear guides 340.1b in the middle of two, 340.2b is arranged between the brace summer 310b and the first balladeur train 321b in stacked mode.Each guide rail 340.1b and 340.2b respectively with two rail 312b that are connected to the brace summer 310b and the first balladeur train 321b, 326b; 313b, 327b cooperates.For this reason, guide rail 340.1b, 340.2b is with single track bearing 341.1b known in the art, 342.1b; 341.2b 342.2b is a main feature.In order to guarantee guide rail 340.1b, the synchronization action of 340.2b promptly guarantees guide rail 340.1b, and the position of 340.2b always limits by the position of adjacent elements is unique, and guide rail 340.1b, 340.2b include around vertical axis promptly perpendicular to by parallel rail 312b, 326b; 313b, the axis cogwheel 343.1b free to rotate on the plane that 327b limits, 343.2b.The parallel inserted tooth rail 314b that each cogwheel 343.1b, 343.2b are relative with two respectively, 328b; 315b, 329b cooperates, and these inserted tooth rails are parallel to rail 312b, 326b; 313b, 327b also is fixed to brace summer 310b and the first balladeur train 321b.
By the spool 334b that is installed in rotation on the second balladeur train 330b, 335b, the second balladeur train 330b (the perhaps anchor clamps of other kind) that is used for the clamping cross bar is slidably mounted in the first balladeur train 321b, along the vertical rail 324b that is connected to the first balladeur train 321b, and the 325b operation.Compare with the foregoing description, the structure that the second balladeur train 330b has is that its width (promptly in the length that strides across the forcing press direction) has reduced.For this reason, the second balladeur train 330b is higher than the first balladeur train 321b and extends, so be used to start the top that the driving mechanism 331b of the spinning movement of anchor clamps can be connected the first balladeur train 321b, the rear side of the second balladeur train 330b.Driving mechanism 331b moves through the front side that corresponding transmission mechanism is passed to the second balladeur train 330b.The balladeur train 321b that width reduces also can be with using in conjunction with the first embodiment of the invention of Fig. 1-7 explanation.
Once more, be fixed to the mid portion of brace summer 310b around the band 322b of first balladeur train 321b operation.And band 322b is fixed to the second balladeur train 330b.Once more, the guiding of the roller by being arranged in its two ends, but the relative first balladeur train 321b freely-movable of band 322b.
Figure 12 also represents two cable unit 350b that can drag, 351b, and it comprises the pipe tunnel that is connected respectively to the brace summer 310b and the first balladeur train 321b.First cable that in the pipeline that is connected to brace summer 310b, extends, with second cable that in the pipeline that is connected to the first balladeur train 321b, extends, on the first balladeur train 321b, connect, so second cable is connected to consumer on the second balladeur train 330b or that be connected to the second balladeur train 330b (promptly being used for rotary clamp, the driving mechanism 331b of adsorption tool etc.).Compare with individual cable, two cables bear lower power, so their life-span increases.Above-mentioned first embodiment also can be equipped with as described two cable units that can drag of present embodiment.
Figure 13 represents the detail drawing of second embodiment of additional middle linear guides.Aspect most of, its structure is corresponding to the structure of the embodiment of discussing in Figure 12.Here it is, and we concentrate the reason of discussing the difference part below.In order to reduce the whole width of crossbeam, middle linear guides 340.1c, 340.2c be another kind of type with positive control cage (positive control cage) 344.1c, 344.2c is the guide rail of main feature.Such guide rail can be by (for example, the INA guide rail MVZ of INA Schaeffler KG or the Schneeberger Formula-S guide rail) of commercial affairs purchase.They comprise that two have V-type section, encirclement center cage 344.1c, the parallel rail 345.1c of 344.2c, 346.1c; 345.2c 346.2c is with respect to two rail 345.1c, 346.1c; 345.2c, 346.2c, the center cage can slide mobile.Positive control is realized that by cogwheel described cogwheel is installed in rotation on cage 344.1c, 344.2c last and be fixed to centre linear guides 340.1c, two rail 345.1c of 340.2c, 346.1c; 345.2c the inserted tooth rail on the 346.2c cooperates.In this embodiment, cage 344.1c, 344.2c form first section of the 320c of telescopic drive mechanism effectively, and middle linear guides 340.1c, the rail 345.1c of 340.2c, 346.1c; 345.2c 346.2c is fixed to adjacent elements, i.e. the brace summer 310c and the first balladeur train 321c.
If cross bar is connected to the balladeur train that bar along the longitudinal extends in some way, two balladeur trains can be independently in the horizontal direction and/or vertical direction carry out displacement, the flexibility of cross bar conveyor system is improved so.Therefore, by mobile balladeur train independently and location crossbeam, the form and the orientation of the position of cross bar and directed workpiece that can be adapted to pick up or that will put down.In addition, the process of transporting to the next stop from a station, the flexible adjustment of workpiece orientation can be accomplished.For this reason, between balladeur train and cross bar, adopt connector, allow cross bar in vertical plane and horizontal plane, to tilt.This for example can realize by universal joint.In addition, because the distance between the balladeur train increases when cross bar tilts, at a connector, two connector places or arrange the compensation mechanism that adapts to the cross bar effective length, telescoping mechanism for example, the distance that changes with compensation along cross bar.
In order to reduce power and the moment that acts on the driving mechanism that is used for drive spindle, gravity compensation mechanism is provided, the parts of compensation crossbeam are in the gravitational difference of actual steering axle both sides, and this gravitational difference is caused by the rotation of crossbeam.Basically, this mechanism can comprise vertical substantially arm, and the support component of conveyer supports above-mentioned arm rotationally and slidably, so turning cylinder just in time is positioned at the top, center (as long as crossbeam is horizontal) of crossbeam.Stride across turning cylinder, the main feature of described arm is one massive.At the other end, described arm is fixed to the center of crossbeam.
Nature does not depart from the scope of the present invention, and the ins and outs of the foregoing description can be made amendment.At first, shown size should be understood to schematically.Conveyor system of the present invention is for punch line with littler or bigger forcing press or multimode stamping machine, and/or littler or bigger punch line or the multimode stamping machine such as 3-9m of the distance between adjacent forcing press station also is suitable.The allowable angle of inclination of crossbeam and rise scope can correspondingly be changed.Similarly, have forcing press or any right mould of any amount respectively in punch line or multimode stamping machine, this conveyor system all is adaptable.This conveyor system can be combined into various forcing press structures, and for example independent patrix of arranging is with supporting or the forcing press pedestal.Conveyor system of the present invention is particularly suitable for the remodeling of existing punch line or multimode stamping machine, but also is suitable for being combined into the equipment of coming of new.
In addition, telescopic drive mechanism can comprise other device that drives first balladeur train, such as leather belt driving mechanism or linear induction motor.If a corresponding gear train is provided, the path that is covered by first balladeur train is different by the path that balladeur train covered that is connected to cross bar relatively.Under a stable condition, if particularly the stroke of conveyer weight extremely short or workpiece is very little, telescopic drive mechanism can be omitted, and with respect to crossbeam, cross bar can directly be driven.
The layout of crossbeam also can be made amendment, and for example, first balladeur train can be shelved on the brace summer or first balladeur train can hang down from brace summer, and promptly the element of driving mechanism can be arranged in the top of each other.Each rail between balladeur train and brace summer and guide groove for example can be replenished or be replaced by roller.
If because the rotation of crossbeam, the unique task that is used for the driving mechanism of rotating horizontal pole is the variation of compensation workpiece orientation, according to the inclined degree of crossbeam,, can simplify this structure by omitting driving mechanism and the mechanical feed device that is provided for the direct compensation change in orientation.
In a word, be used for the conveyer of transmitting workpiece in a kind of forcing press that should be pointed out that the invention, it is simple in structure, allow long transportation stroke and transmitting workpiece quickly and effectively.
