Abstract
The invention relates to a support, particularly a profiled or wire frame of a continuous transport device for transporting thin and bendable objects, panels or sheets through a drying tunnel or through a tunnel for thermal treatment or the like.
This support is characterized by the shape of its surface which receives the objects to be transported. The purpose of this shape is to prebend the panels to be transported when they are received approximately horizontally so as to prevent them from bending in vertical direction under their own weight as soon as they are lifted into a quasi-vertical position for or during transport. During this second-mentioned deformation, contact points which are very detrimental to the quality of the dried products are established between the panel and the preceding wire frame.

Description
~~'~~.°~ ~.
The present invention is concerned with supporting devices which are known as wire frames and are mounted in parallel one behind the other on one or more chains (or similar devices). In this manner, continuous transport of the panels or sheets is assured so that these can be sent through a tunnel for drying or thermal treatment, or can be disposed solely in a waiting position between two consecutive manufacturing processes in the same production line.
Transport systems of this type are indeed known and are frequently employed. A typical example from the metal packing industry is schematically illustrated in Figure 1. Thin iron sheets or aluminum panels, which are varnished, printed or coated for protection or on optical grounds, are required in the metal packing industry. Here, it is necessary for the sheet metal panels to dry or polymerize for about 10 minutes at temperatures between 120°C and 220°C so that the color or the like adheres firmly to the metal and can thus fulfill the protective or decorative function. This application serves only as an example since the wire frames of the present invention can function to carry all types of flat, thin objects which are transported in an almost vertical position. The time for which the objects are subjected to the treatment is limited by the length of the tunnel.
Figure 1 shows a panel or sheet coating installation "a" and a belt transport arrangement "b" for introducing the panels between the wire frames 1 of a continuous transport device "c".
An unloading device with a belt transport arrangement "d" in the direction of a stacker "e" is likewise illustrated.
Figure 2 shows, in plan view, a typical wire frame 1 for a transport device for the transport of metal panels through a ~;~r~~r drying tunnel. In Figure 3, the same wire frame can be seen in profile. A sheet metal panel of maximum length and maximum width is illustrated in Figure 2 by dashed lines.
The design of this wire frame 1 results from a compromise between two contradictory requirements; namely, to make available a large and robust support surface which is suitable for a large number of different panel or sheet sizes, and to provide a minimum mass so as to decrease the energy consumption required for multiple heatings to operating temperature per hour. The wire frames normally consist of welded or riveted, flat steel shapes as depicted in Figure 2. On the other hand, until today one has adhered to the practice of placing both their surfaces between two parallel planes in order to again align them on a rolling slab without difficulty if they are dented or deformed due to a transport incident (Figure 3).
These wire frames are installed on one or more chains 2 (Figure 4). In order that the transported panels distinctly lie on the surface which is opposite the just printed or coated side, that is, on the backside (so that the front side does not come into contact with the preceding wire frame), the nature of the attachment of the approximately horizontal wire frame to the chain or chains provides for an angle of 15 degrees between the vertical and the support plane of the wire frame. In well-designed transport systems, U-shaped parts 3 secured to the tops of the wire frames serve as transverse connections between two respective, consecutive wire frames. Due to this cage-like arrangement, the wire frames, which move in a row, are practically undeformable.
Such designs were completely satisfactory as long as the ratio of the lengths and heights (dimension of the quasi-vertical panel during transport) to their thickness was such that the panels did not bend under their own weight and largely remained straight while supported against the wire frames as can be seen in Figure 4, reference character 4.
The search for more effective use of the metal leads to an enlargement of the individual panel and a decrease in its thickness. In the conventional transport devices, the large and thin panels bend readily, as can be seen via the reference character 5 in Figure 4, so that the undesired contacts between the panel and the backside of the preceding wire frame occur ever more frequently. This results in defective protection and/or unsightly spots which make the panel virtually unusable. This tendency is also found in panels of light metal which is less rigid than steel.
Supports of transport devices having an upper run and a lower run are known from U.S. patent 2,593,415 and U.S. patent 1,'736,866 and serve to transport flat objects. The supports of these transport devices are flat. The objects are introduced in horizontal orientation in the region of the transport device where the supports reverse direction and are then raised into an approximately vertical position by further transport of the run.
The goal of the present invention is to eliminate these drawbacks. It is based on that one must employ a large force in order to bring a flat object consisting of a material which is resistant in two mutually perpendicular directions into a bent form. In effect, the deformability of the panel is lost due to the shaping which occurs in different directions and a large amount of force thus becomes necessary. Accordingly, to prevent a panel from bending about a horizontal axis as illustrated in Figure 4, reference character 5, it suffices to proceed in such a manner that the panel is bent about a perpendicular axis before one brings it into an almost vertical position in which, per the known device, the danger of undesired deformation exists.
This prebending is achieved in a simple fashion by means of the ~~ wire frames which are the s,abject of the present invention.
The present invention provides a support member for a continuous conveying installation for conveying plate-shaped and bendable objects, the conveying installation having a longitudinal axis, the conveying installation receiving the 1C plate-shaped objects with each plate-shaped object and the support member being in an f=_ssentially horizontal position and conveying the plate-shaped objects in direction of the longitudinal axis in an upright position, the support member defining a surface, the surface of the support member being 15 shaped such that, when the :support member is in an essentially horizontal position, a plate-shaped object placed on the surface of the support member is bent downwardly due to gravity about an axis located in a vertical plane extending in direction of the longitudinal axis of the conveying 20 installation, whereby, when the plate-shaped object is moved into the upright position prior to and during conveyance, the plate-shaped object is prevented from being bent about an axis which extends approximately perpendicularly to the vertical plane extending in axial direction of the conveying 25 installation; the support member comprising a plurality of shaped metal wires which are connected to each other, the metal wires being arranged in two planes, the metal wires of the two planes being connected to each other in a manner such that the surface of the support member has a bent shape for bending the 30 plate-shaped objects.
The invention is described in greater detail with reference to the Figures. There is shown:
Figure 1 a schernatic side view of a transport device with supports for flat transported articles, Figure 2 a plan view of a support, Figure 3 a front. view of a known support, Figure 4 a side view of a plurality of supports, Figures 5, 6, 7, 8, 10 front views of different embodiments of supports according to the invention, Figure 9 a detai_1 view of a support, Figure 11 a plan view of a support located in the transport device.
The most direct. realization of a wire frame (flanged frame, profiled frame) confc>rming to the present invention consists in bending an ordinary wire frame to give it a form corresponding to a section of a cylinder as illustrated in Figure 5 or to bend it slightly so that an open V shape is obtained as illustrated in Figure 6. The wire frames of the invention can have lateral extensions which point upwards (Figure 7) or downwards (Figure 8).
In the first three exemplary embodiments, the wire frame bends the panel in such a manner that the lateral portions lead the center of the panel during transport in vertical or almost vertical position. The opposite is the case in the exemplary embodiment of Figure 8. The wire frames can bend the panels lIl 5a _.
one or the other fashion, both bending directions lie within the scope of the present invention.
To simplify the manufacture of the wire frame according to Figures 7 and 8 by means of conventional tools, the flat steel shapes 6 which have a rectangular cross section and serve to produce the lateral support extensions 7 (arms) can be replaced by trapezoidal shapes. This is illustrated in Figure 9. In this manner, the lateral support extensions 7, during production, automatically form the desired v-shaped angle in the region of approximately 180 degrees with respect to the central portion of the wire frame.
If is it not possible to design the panel feed (belt transport arrangement "b") of Figure 1 so that the panel sides can be raised before they are introduced between two wire frames, and if the wire frames are provided with raised lateral portions, that is, when they have profiles according to Figures 5, 6 or 7, the design of the wire frame of Figure 2 is no longer suitable for the automatic loading of "toothed" panels having lateral zigzag margins (see the dashed line in the left center of Figure 12, reference character 8). The lateral cutouts of these panels, which one encounters ever more frequently in the metal processing industry, is intended to avoid the metal losses arising from a straight cut when the objects to be produced are assigned to the surface of the panels in a pentamerous arrangement for varnishing or printing. In general, this involves round objects such as covers or can bottoms, closures which are produced in large quantities and whose material costs play a significant role in the manufacturing cost.
The illustration according to Figure 2 no longer conforms to these conditions since, during automatic loading of the panels, _ 2011964 that is, as soon as these perform a translational movement along the wire frame axis, there exists the danger that the margins 9 of the toothed sheets 8 will collide with the lateral support extensions 7 whose outer ends are raised above the central portion of the panel.
Figures 10 and ~~ show a wire frame which eliminates this drawback.
In such a wire frame, the toothed margins are supported by straight and continuous profiles 121 and 122 which run parallel to the symmetry plane of the wire frame and are bent at the outer portion so that rectangular frames, which are welded or riveted to a central portion 15, are produced, for example. This structure is strengthened by means of inforcements 16.
In an embodiment which is to be preferred, the straight profiles 121 and 122 have an almost trapezoidal cross section so that, upon assembly, one automatically obtains an angled surface as illustrated in section in Figure 11. The frame or frames 15, as well as the reinforcements 16, are further produced from flat bar steel having a rectangular cross section.
Figure 11 shows a wire frame which, by way of example, has two lateral frames 121 and 122 on either side. This number can be reduced or increased without departing from the scope of the invention. Multiplication of the profiles 121,122,12n allows the sides of a large number of panels of different size to be better supported. However, increased energy consumption upon heating for the treatment also occurs due to the increased mass of the wire frames.
Likewise, profiles 121,12n which have a rectangular cross section and are used for the production of the lateral frames remain within the scope of this invention if they have an 20?1964 unbroken length parallel to the symmetry plane of the wire frame.
Figure 10 shows that, when the profiles 12 have a trapezoidal cross section, each connection 121-122, 122-12n forms a new portion which has an angle of inclination and increases the desired curvature of the panel.
On the other hand, the automatic loading devices have mechanisms which decelerate and hold each panel introduced into the transport device "b" (Figure 1). Similarly, the unloading stations of the same Figure are equipped with belts which serve for withdrawal and are frequently supported by magnetic or other rolls. The form of the wire frame must be such that impediments along its path are avoided.
The wire frames of the present invention exhibit the desired conditions so that these impediments are avoided.
On the one hand, the profiles and the outer longitudinal frames 122 or 12n do not extend over the entire height of the wire frame in order to permit the mounting of a magnetic or pneumatic panel braking device 13 which is illustrated solely by its outlines in the lower right of Figure 11.
On the other hand, a large, curved cutout between the sides 121 enables one to surround the horizontal belts and the associated magnetic and pneumatic rolls. The latter remove panels which, due to the movement of the wire frame, are pressed down at the end of the transport device and are forwarded to a transport device 18 in accordance with the reference character "d" of Figure 1.
In addition, a central bracket 17, which is secured to the frame 15 in such a manner that it passes between two groups of withdrawal belts 14, prevents the high and narrow panels which have been bowed due to the form of the wire frame from sliding down between the frames 121.
The U-shaped parts which serve as transverse connections between consecutive wire frames are secured to the horizontal sides of the frames 121,122,12n as can be seen from Figure 11.
Such a wire frame (profiled frame, flanged frame) comes into contact with the chains 2 via its two flanges which project from the sides of the frame 15. These flanges extend into the openings of the chain links. The wire frames are held in a classical manner by slotted keys.
l0 A wire frame of the type which exhibits two symmetry planes before the U-shaped parts 3 are applied can be used indiscriminately to form a transport arrangement in which the center of the curved sheet points forwards or backwards. The mounting of the transverse connecting pieces 3 (U-shaped parts 3) alone determines the manner in which the transport arrangement functions.
These wire frames are intended, in particular, for transport arrangements of drying tunnels installed in printing and varnishing installations for metal panels which are used, by way 20 of example, for the manufacture of packing means (cans, metal containers, drums, etc.), bottle closures (caps, crowned corks) or diverse metal articles made in large production runs (plates, toys, games, etc.).

To simplify the manufacture of the wire frame according to Figures 7 and 8 by means of conventional tools, the flat steel shapes 6 which have a rectangular cross section and serve to produce the lateral support extensions 7 (arms) can be replaced by trapezoidal shapes. This is illustrated in Figure 9. In this manner, the lateral support extensions 7, during production, automatically form the desired v-shaped angle in the region of approximately 180 degrees with respect to the central portion of the wire frame.

Figures 10 and ~~ show a wire frame which eliminates this drawback.
In such a wire frame, the toothed margins are supported by straight and continuous profiles 121 and 122 which run parallel to the symmetry plane of the wire frame and are bent at the outer portion so that rectangular frames, which are welded or riveted to a central portion 15, are produced, for example.
