Description

The device that is used for stacking flat, flexible objects
The present invention relates to a kind of by claim 1 as described in the preamble be used for flat, flexible, article upright on a narrow side are stacked on a device that piles up in the frame in stand up position.
Treat the flat parts stacked on one product, may have bigger difference aspect length, height and the elasticity as sending article.Its transportation is carried out with as far as possible little spacing successively, preferably is clamped between the elasticity load-transfer device (pressure zone system).For the front edge that does not make article when piling up is run into the lagging dege of the article that move ahead, and cause thus and block, be necessary the lagging dege of the article that move ahead and the front edge of heel article are staggered just so-called " release access road ".
In order to realize this purpose, a kind of main shaft that piles up of driving has been described in DE 3 317 865 A1, before it is positioned at each hermetically and piles up frame, and the aft section of article on ascent direction is towards stacking deflection, thereby the article of heel can not run into lagging dege, but run on the article that piled up in the side.Power importing by main shaft is carried out on the lower edge of article.But this can cause, and especially high article that is to say that owing to inertia reverses the back upward discharges " access road " in the angle too late or not even.Pile up the article that up to the present main shaft can only be used to have the tiny length difference effectively.The general lagging dege orientation in its position according to the shortest article to be piled up.If the length between long article and the shortest article is than greater than 2, its effect is limited for long article so.
Also known other steering component, for example the lever that can swing is similar to the turn-out track wing (Weichenfluegel) (US Re.34,330=US 34330E).Be configured to adverse current turn-out track element at this steering component, that is to say at the transporting direction of the reverse article of state lower prong that do not produce and point out from centre of gration.If steering component does not sail into before its front edge by article catch up with, so will with article generation front shock, this can cause destroying.
In order can be correspondingly the article of big specification limit to be piled up, propose according to DE 101 18 758C1, set gradually a plurality of steering components.
What be not much accounted of in this solution is, especially for big article specification limit, always such article can occur, it is successfully piling up the back because its special article characteristic is gone into access road to go up thereafter angle lapping, and can have the danger of diving to the subsequent article that enter thus.Disadvantageously high in addition impact loading is to article, and relative velocity is higher between article and the steering component.
Therefore task of the present invention provides a kind of device up to specification, its not only will be to be piled up when gently handling article the lagging dege of article from access road, shift out, and avoided the article that successfully piled up because it is flexible again in the impouring access road.
According to the present invention, this task solves by the described feature of claim 1.
Stackedly be provided with the part that on sense of motion be positioned at back that one or more hook component be used to make bigger article to the side on the transportation plane of piling up the path in the frame along the direction to the stacking post at article at this and turn to and support, these hook components are being fixed on the end on the axle of a controlled driving respectively.Greater than the thickest article, and this free-ended outline makes the part that is positioned at the back on transporting direction of the bigger article that piled up can be subjected to support to be used to discharge access road to the size of the distance on transportation plane to profile to the distance on transportation plane in hook component free-ended.Being provided with sensor in addition is used to detect with the front edge and the lagging dege of the article of given speed transportation and is provided with processing mechanism and be used for obtaining front edge and lagging dege is being determined position constantly by sensor signal.Be designed for the controller that activates the driver train of hook component axle according to this time dependent position, make and to activate by a sensor signal that produces by the front edge of the article that enter for entering the article that pile up in the frame, hook component is so directed, make article sail hook component into, and the lagging dege of the bigger article that piled up is shifted out from access road.Hook component and article synchronized movement ground are shown from the transportation plane, make article not arrive with hindering and pile up in the frame.The size of the distance of hook component and stop wall makes support function keep in showing process always, has definite lap up to the lagging dege of the front edge of the article that enter and the article that supported that piled up.The sensor signal that is produced by the lagging dege by the article that enter triggers hook component put again and gets back to it and support antemarginal initial position then.Just hook component unified the function that the lagging dege of the narrow article that will grow releases and the unsettled article of avoiding especially big specification successfully pile up the back since on the back free angle fracture and support function in the impouring access road.
Preferred construction scheme of the present invention is described in the dependent claims.
In order to make support function during the hunting motion of hook component, keep long as far as possible, is favourable when hook component has one during from part that centre of gration stretches out, connecting a part with outline of approximate circle arc-shaped bend on this part, its flexural center is in the centre of gration place.
Also advantageously, the quantity of hook component with and distance from the base plate to the axle so select, make and can support the article that remain to be piled up with differing heights.
In order only to apply very little load to the article that pile up by hook component, hook component with send the part that article contact and preferably have very little friction coefficient.
For short article are carried out glitch-free piling up, advantageously be provided with one between roller and the hook component and pile up main shaft and be used for short article piling up.
Subsequently describe the present invention with a kind of embodiment with reference to the accompanying drawings.
Accompanying drawing illustrates:
Fig. 1-3 shows the diagrammatic top view of stack device in the different phase of the process of piling up;
Fig. 4 shows cutaway view A-A.
Article 3 are sent in the load-transfer device 4 of pressure zone system individually with clamping and pile up in the frame.The pressure zone system favours a stop wall 11 guiding of piling up frame by slewing rollers 14 towards the load-transfer device that piles up frame far awayly unlike another load-transfer device, wherein flat article 3 stops at this stop wall place.Thus article 3 just a side guided to be sent to and piled up in the frame.On delivery conduit, there is a grating 5 to be used to detect the article 3 of arrival in the entrance of piling up frame.To the path of stop wall 11, the hook component 1 of article 3 by rotatably arranging successively up and down, these hook components are being fixed on the end on the axle 13 by motor 9 controlling and driving.This 13 is positioned at the face after a while that leaves stacking 7 transportation planes, and this transportation plane is determined by pressure zone system and guiding mechanism 12.Follow thereafter be the pressure zone system to stop wall slewing rollers 14 the most closely.Then, on delivery conduit, be provided with one and pile up roller 6.Each article 3 piles up roller 6 bendings with respect to the angle of stacking orientation around this by leading to the transporting direction that piles up in the frame.By reducing of flexure stress, the lagging dege of article 3 shifts out from access road transverse to transporting direction.In order to support and quicken this cross motion, before piling up roller 6, be provided with a kind of known main shaft 8 that piles up in a side towards stacking 7.The lagging dege that piles up main shaft 8 that stretches out far away of long article 3 shifts out from access road by hook component 1 in addition.In initial position, this hook component 1 occupies such position, and the article 3 that sail into sail the open side (Fig. 1) of hook component 1 into.
Hook component 1 synchronously rotates along the direction of arrow with the article 3 that sail in the stack device, makes it corresponding to the front edge of its selected geometric modeling above the article that sail into, up to its complete " disappearance " back (Fig. 2) on the transportation plane.Hook component 1 has been unified the function that the lagging dege of long article 3 is released and has been avoided the unstable article 3 of for example big specification successfully piling up the back because fractureing of free angle and support function in the impouring access road on the back.
So construct hook component on geometric configuration, the lateral surface of hook component 1 fashions into and is similar to the circuit orbit section, the centre of gration place that is centered close to hook component 1 of circuit orbit section.All connect the tangential rounding of curve element thereon.
Hook component 1 is as far as possible little with respect to the frictional property of article material with the surface that it contacts with article 3 to be piled up.
During the process of piling up, the support function that is provided by the outline of hook-type geometric configuration remains to the front edge of the article 3 that sail into always for thin big unsettled article 3 sufficiently overlapping with the article that pile up obliquely.If article to be piled up 3 sail in the stack device far enough, hook component 1 is so located between it so, make the back side of hook-type geometric configuration from transporting flat, shift out, and a transverse acceleration that rises continuously is applied on the lagging dege zone of article 3 at this.
According to the article characteristic, this motion parts of hook component 1 carries out (according to Fig. 3 against transporting direction) in company with the article 3 that sail into or against the transporting direction of the article 3 that sail into, and wherein the hook component 1 along the transporting direction rotation has with respect to the very little advantage of article 3 relative velocities of sailing into.
If hook component 1 is in initial position again, its article that on this position, stop and support piling up so.The article 3 that connect later on of following processes restart then.The motion process of hook component 1 is by control of regulating mechanism and monitoring, wherein this regulating mechanism according to the Item Information that when pretreatment, obtains and near the signal of grating 5 on the front edge of article to be piled up start corresponding program.
