Description

Method for filing sheet-shaped objects and

Arrangement for carrying out this method

The present invention relates to a method for depositing sheet-like objects, in particular for depositing electrodes and / or separators for constructing an electrochemical energy store or parts of such electrodes or separators, and to an arrangement for carrying out such a method.

The handling of leaf-shaped objects plays in a row very much

different technical fields an important role. In this case, the problem of separating these leaf-shaped objects occurs again and again

Appearance. Especially in the field of page printers, which are loaded with stacks of paper sheets, or in the field of

Numerous attempts have been made to solve the problems encountered in bill handling.

For example, DE 193 03 70 A1 discloses a device for removing sheet-shaped recording media from a stack resting on a height-adjustable base plate, in which the respective uppermost recording medium of the stack is detected by a circulating friction belt and by a conveyor belt circulating with the transport speed and an opposing brake band formed neck of a transport path is performed. In this device are slightly inclined in the transport direction in the

disposed stack arranged receiving bottom plate openings, by the application of a negative pressure, the friction of the lowermost Record carrier of the stack is controllable with respect to the frictional belt which detects it.

DE 20 05 270 A1 discloses a transport device for sheet-like documents consisting of a hollow drum, in which a vacuum chamber is provided, which is connected to a vacuum source via a hollow shaft and has suction openings in its cylinder jacket. Behind a suction opening or a group of suction openings in this transport device, a pneumatically operated diaphragm valve is arranged, which connects these openings optionally with the vacuum chamber. A pneumatic logical

Control is connected to the diaphragm valve to connect the suction ports to the vacuum chamber when a document is to be held on the cylinder jacket of the drum and to interrupt the connection to the vacuum chamber when no document is to be held or when a previously held document is to be released.

DE 22 01 254 B2 discloses a device for separating of

Sheet material from the bottom of a stack to a pair of conveying rollers using a stationary stacking table with a reciprocating slide plate, which detects the respective lowermost sheet of the stack at its trailing edge, moves over the stacking table and enters in conveying rollers, associated with the stacking table Saugbohrungen through which each of the lowermost sheet is subjected to a negative pressure, and with

Support rails for the stack. These stationary support rails form between them suction channels, which are open at the remote from the conveyor rollers ends relative to the outside air. The slide plate has on its upper side to below the lower edge of the contact surface for the leaves to be separated passing through grooves, each of which is aligned with one of the suction channels formed between the support rails. In this way, the trailing edge of the next sheet to be conveyed is pulled down during singulation of the lowermost sheet. Similar devices are described in the published patent applications DE 26 50 438 C2, DE 30 23 157 A1, DE 32 20 237 C2 and DE 34 04 215 A1.

Further, DE 34 41 479 A1 discloses a vacuum-operated

Lifting devices for air-permeable sheet-like objects of variable outline, in which a suction chamber containing a housing having a plurality of evenly distributed suction openings in the bottom of the housing is provided, and wherein each suction port is associated with a switching valve, which closes the opening against the atmospheric pressure closing valve member one passing through the opening down, from the

Housing protruding valve stem and one with the valve member

having associated switching piston, which on the side facing away from the valve member at a closed opening on its full diameter and released opening on a reduced diameter of

Atmospheric pressure is applied.

Because of the particularly low dimensional stability of sheet-shaped electrodes or separators for constructing an electrochemical energy store or of sheet-like parts of such electrodes or separators, technical teachings which offer advantages in the field of paper processing are generally not applicable to the handling of electrodes and / or separators for the construction of an electrochemical energy storage transferable. The present invention has for its object to provide a technical teaching for handling sheet-shaped objects, in particular also advantages in handling sheet-shaped objects with low stiffness from electrode materials and / or separator materials in connection with the production of electrochemical energy storage offers.

This object is achieved by a method for depositing sheet-like objects or by an arrangement for carrying out this method according to one of the independent claims.

According to the invention, a method for depositing sheet-like objects is provided, in which a plurality of such objects are successively superposed, and in which at times one or more objects are removed from above again. It is also provided that the objects offset from each other and / or rotated against each other are superimposed. In this context, a sheet-like object is to be understood as a flat article, preferably a thin flat article, that is to say preferably a flat article whose dimensions in a direction perpendicular to its surface are substantially smaller than the dimensions of the smallest sections which are completely within the surface lie. Examples of sheet-shaped objects are, in particular, electrochemical materials, such as, for example, electrode materials or separator materials, such as are used in the production of electrochemical energy stores.

A plurality of such objects in this context means a number of objects greater than one.

Arrangement;

FIG. 7 shows a fourth arrangement of sheet-shaped objects; Figure 8 is a vacuum lift according to a preferred embodiment of the invention.

As shown schematically in FIG. 1, in this exemplary embodiment the leaf-shaped objects are offset relative to one another, but not rotated relative to one another, so that the edges or certain subregions of a second leaf-shaped object lying below a first leaf-shaped object are freely accessible. When the uppermost sheet-like object 5 in Fig. 1 is to be raised, the underlying sheet-shaped object 4 can be prevented from being lifted by the overhead sheet-shaped object 5 by holding down this sheet-shaped object 4.

At the same time, the underlying other sheet-shaped objects are also prevented from being lifted. For holding down the leaf-shaped objects, in particular the leaf-shaped object 4, for example, the points 15a, 15b, 15c and 15d offer, on which, for example, with the aid of a mechanical hold-down pressure can be exerted. FIG. 2 shows a similar situation using the example of sheet-shaped objects which are placed one above the other in a twisted manner. To hold down the underlying leaf-shaped objects offer here, for example, the points 16a, 16b, 16c and 16d. A similar situation is shown in FIG. 3, wherein here the sheet-shaped objects are rotated relative to one another and staggered relative to each other.

Preferably, the at least one point or at least a part of this object is at the edge of the surface of this object. Particularly preferably, the objects used are at least partially air-permeable objects. The staggered and / or twisted deposition of the sheet-like objects shown in FIGS. 1, 2 and 3 respectively allows a particularly effective, reliable and simple separation of these leaf-shaped objects, especially if these are easy due to their material properties and an associated adhesion or cohesion adhere to one another or if this, in particular in the case of at least partially air-permeable

Objects are sucked together in a plurality of a vacuum jack 1 together. In FIG. 5, a further preferred exemplary embodiment is one

FIG. 6 shows a further preferred exemplary embodiment of an arrangement according to the invention, in which preferably on the lifting device 1

Information technology devices 7 are attached, by means of which the position of a sheet-shaped object 5 can be detected, so that the

Lifting device 1 can be aligned according to the detected position. This information technology device 7 preferably comprises one or more cameras, which preferably receive or record images from the edges of the sheet-like objects, from which with the help of information technology

Method the position of the sheet-shaped objects or a sheet-shaped object can be determined. Preferably, procedures of the sample detection for use, particularly preferably methods for

Edge detection.

Edge detection is part of image processing segmentation that attempts to separate two-dimensional areas in a digital image. Many methods for automatic segmentation are known.

Basically, they are often divided into pixel-, edge- and region-oriented methods. In addition, a distinction is made between model-based methods based on a specific form of the objects and texture-based methods in which an internal, homogeneous structure of the objects is also taken into account.

The boundaries between the procedures are often fluid. Also, one can combine different methods to achieve better results.

So-called edge operators should detect the transitions between these areas during edge detection. These transitions are marked as edges. In contrast, however, a single area should also be recognized as such and not be divided by an edge into two parts by a good edge detector. An edge detector calculates its corresponding edge image from an image, in which all edges can be seen accordingly. To achieve this, each pixel is reset by a calculation using a matrix. In edge-oriented methods for segmenting digital images, the image is searched for edges or object transitions. Many algorithms do not yet provide closed edges; These must first be combined with other methods to include objects. However, this is often not necessary for determining the position of leaf-shaped objects of known form. Edges often lie between the pixel regions of an image. The results of an algorithm may be polygons (or lines), but some operations also provide the edges as differently colored pixels. With methods such as the Sobel operator and the Laplace operator, as well as a gradient search, pixels belonging to an edge can be found. These are still loose and must be completed with edge-tracking algorithms. A popular method of creating a contiguous object silhouette, or at least edge sequences from the edge pixels, is the live wire method of the authors E. Möllensen, WA Barrett, and JK Udupa. The idea can be visually compared with a navigation system, which determines an optimal path from the start to the destination. Optimal in the context of segmentation means that the path between start and destination always leads over the strongest edge pixels. The optimal routing is then a standard problem of computer science and can be solved, for example, with a breadth first search. Another very well-known method is the watershed transformation, which works on grayscale images and always delivers closed edges. Other methods include parallel and sequential edge extraction, optimal edge search, the Feltszwalb-Huttenlocher algorithm, Active Shape Models and Snakes.

In the embodiments of the invention shown in Figures 4, 5 and 6, preferably at least one lifting device 1, more preferably a vacuum jack 1 is provided which is rotatably mounted on a lifting device 2 about a vertical axis 9 and / or in a horizontal plane 10 , The vertical axis 9 is preferably arranged substantially parallel to the direction of gravity and thus substantially orthogonal to the surfaces of the stored or raised objects. The horizontal plane 10 is preferably arranged perpendicular to the vertical axis 9.

These or further embodiments of the invention preferably have at least one hold-down device 3, through which at least one first object 4 is held while at least one lying over the at least one first object 4 second object 5 is removed. As a hold-down device 3 preferably mechanical gripping devices, electrostatic holding devices or working with a vacuum or vacuum hold-down come into question.

The embodiment of the invention shown in Figure 5 has a

Hold-down 3, which is constructively connected to the vacuum generator 1 or with any other lifting device such that this holddown in kinematic reference systems of the vacuum lift does not or at most in the vertical direction moves when the vacuum lift in relation to a stored or horizontal object in horizontal Direction moves. As shown in Figure 5, while the hold-3 is preferably rigidly connected to the vacuum jack 1 or with the other lifting device or at least connected so that a relative movement between the hold-down and the vacuum lift in any case is not possible if the vacuum lift or other lifting devices themselves moved horizontally in relation to a stored or lying object. Preferably, as shown in FIGS. 4, 5 and 6, at least one vacuum jack 1 has a plurality of pressure chambers 6. These

Pressure chambers 6 are preferably independent of each other

Negative pressure acted upon. Particularly preferably, the pressure chambers are arranged in the horizontal direction 10 against each other displaceable. This has the advantage that the position of the pressure chambers of the shape of the sheet-shaped object can be adjusted.

Information technology device for alignment and / or positioning a lifting device based on the detected by this or other information technology device location of an object to be removed. The information technology device for detecting the position of a

an object to be removed preferably has a camera 7.

As shown in Figure 7, the sheet-shaped objects 4, 5 are preferably rotated against each other, particularly preferably rotated by an angle of about 26 degrees against each other or alternately individually or in groups are stored in two interpenetrating stacks, which are rotated against each other. The sheet-like objects can be secured at their ends or edges by limiting elements 17, 18 against unintentional twisting or displacement. Such limiting elements 17, 18 may also preferably support the intended stacking of the sheet-shaped objects in order to keep deviations from the desired position as small as possible.

Vacuum jack or vacuum gripper for use in connection with an inventive arrangement shown, such

Vacuum jack 1 preferably a number of pressure chambers 6 with respective vacuum ports 20.

The vacuum lift preferably has a plurality of hold-downs 3, which in the case of that shown in FIG

Embodiment preferred as a spring retainer 3 are formed. The points of application of these hold-down devices are preferably located as close as possible to the edge of the vacuum gripper 1 in order to prevent undesired buckling of the sheet-like objects when lifted by the vacuum gripper. If the sheet-like objects are separator foils or

Electrodes for the production of galvanic cells, is the

Vacuum jack preferably operated with a negative pressure of 0.7 bar. In these cases, the hold-downs preferably exert a force of a total of 18 N on the leaf-shaped object to be held down.

The invention is expressly not limited to applications in which only individual leaf-shaped objects are raised or deposited. In the production of electrochemical energy stores, in particular of galvanic cells, embodiments of the invention are preferred in which sheet-shaped objects of different types and / or compositions, preferably electrodes and / or separator foils are raised or deposited together or in such a way that first an electrode is lifted and then, without first laying down the electrode, with the same vacuum jack, a separator foil or in reverse

Preferably, an annular gap is provided around the anode, which is preferably about 2mm wide. The cut Separatorfolien are often slightly larger than the electrodes. The invention is therefore expressly applicable to leaf-shaped objects of different sizes or shapes.
