Abstract

The method allows to manufacture webs or plates of thermoplastic material wherein a multitude of profiled bodies (17, 18) are formed, taped towards their summits and connected at their bases in the plane of the material web. The formation of profiled bodies is carried out in a thermoplastic phase of the material by means of spike-like tools (12) of which the temperature is lower than that of the material. The spike-like tools (12) deform, respectively, profile the plastified material by drawing the material until it solidifies following the cooling of the material, respectively until it reaches a temperature lower than the plastification point of the previously soft material. Also disclosed is a device for continuously or discontinuously producing a multitude of hollow standing bodies (17, 18), optionally tapered towards their summits and connected at their bases, from webs or plates of thermoplastic materials; the profiled bodies (17, 18) are formed on one side or on both sides of the plane (16) of the material, and are connected through the plane of the material (16) forming the base.

Description

Process for the production of a

Variety of protruding on one or both sides

Profiles of sheets or plates made of thermoplastic, deformable material.

The invention relates to a process for the production of webs or sheets of material with thermoplastic properties, a plurality of hollow profile bodies, tapering to the tip if necessary, which are connected to one another at the base by the material web level, being formed from the material level.

This formation takes place in the thermally plasticized state of the material with the help of pin-shaped tools, these having a temperature which is below the temperature of the plasticized material. The pin-shaped tools deform or profile the plasticized material due to a pulling effect that lasts until the previously soft material has hardened due to cooling or falling below the thermal plasticization range.

The invention further relates to a new device for forming a plurality of hollow, possibly tapering to the tip, at the base interconnected profile body made of a sheet or plate of material with thermoplastic properties in continuous or discontinuous operation, the profile body on one or both sides can be formed from the material level, however i The area of the material level that forms the base should remain connected flatly.

This device according to the invention is particularly suitable for carrying out the above-mentioned method. An important product, which is constantly developing in terms of its importance, particularly in the field of plastics processing, are so-called dimpled sheets, which have projections or profiles (so-called dimples) formed on one side primarily from a material level, which have different spacings can be formed to each other.

These profiles can have any geometric shape, in particular pyramid-shaped, truncated cone-shaped or also cylindrically tapering. Such prof liert webs, or plates (dimpled sheets), which are mostly covered in the plane of the profile tips by a flat material web and thus additionally reinforced, are already in a wide variety

Areas of application technology have been used and proposed. They can be found particularly in packaging technology, for example in container construction, as stiffening underlays for fragile or sensitive goods such as fruit, eggs, ampoules, electrotechnical articles (light bulbs), as stiffening material for cardboard boxes, as sound and temperature insulators, in Construction for the insulation of walls or roofs, in aircraft, body or floor construction, in solar technology and much more.

However, it has been shown that sheets, plates, foils or other materials known as knobs, the profiling of which is formed on one side only, in which therefore have only one knot formed on one side to the web or material level, with respect to their mechanical strength — and this applies quite generally regardless of the material used — have considerable defects. The sheets or plates are easily bendable, they tend to form cracks in the area of the base of the profile body, that is to say in the area of the remaining material, and they usually have to be used in double layers in order to counter these defects.

The lack of stability is particularly noticeable

Stiffening tasks, but also extremely disadvantageously noticeable when used as support underlay for fragile goods, so that additional support and stiffening elements are required in order to perform the task to some extent.

It has already been proposed (DE-OS 22 58 513) to carry out the profile formation from the material level on two sides, with mostly upper and lower profiles being produced alternately. Although this “knobs” on both sides already leads to a considerable improvement in the physical properties of the profiled end products (knobs), the technology used in the known method, on the other hand, does not permit the technical production of sheets or plates of any profile type, profile size etc., which are profiled on both sides, continuously , undisturbed operation not subject to faulty batches.

The known method therefore deliberately requires the restriction to a very specific ratio of the profile length (nub height) to the profile diameter at the base (material level). It also requires the use of only very specifically trained tools for the actual pulling effect that creates the profile. The tools should be available as pointed needles. The required ratio of profile length to profile diameter at the base in conjunction with a likewise required and thus restricting minimal surface of the material connecting the profiles to the base limits the area of use of such profiled materials to a considerable extent and, for example, as a carrier material hardly suitable for larger individual parts of fragile goods due to the extremely dense sequence of knobs (profile sequence). Furthermore, due to the requirement to maintain a ratio of profile length to the base profile diameter of "greater than 2: 1" when forming profiles on both sides, there is a risk of a considerable reduction in the wall thickness of the profiles with comparatively thick tips, as a result of which the mechanical stability of the profiles can be reduced in this way, that - depending on the material used - the breakdown of individual profiles or entire profile groups is inevitable.

That the demand made for compliance with the ratio of the profile length to the profile diameter considerably restricts the shape of the profiles and e.g. relatively broad or large profile ends or short, rounded profiles with a smaller or the same profile length than the profile diameter no longer allows at all, of course.

It is easy to see that in the case of double-sided, closely spaced profile formation with thickened tips and the required ratio of profile length to profile base diameter, material thinning cannot be avoided during the drawing process. The use of exclusively pointed pins as drawing tools for profile formation has also proven to be a disadvantage. Although a point-like deterrent and thus point-like thickening is achieved at the point of contact of the cold tips with the hot material web, as practice has shown, this can easily penetrate the pointed tools, particularly in the case of materials with a narrow softening area, such as glass mass manage the material, so that there are considerable incorrect batches during operation.

Another disadvantage of the known method is the dependence of the profiles on the fixed, unchangeable shape of the pointed pins as drawing tools in that other geometric shapes of the profiles than long, thin, extremely pointed knobs cannot be produced. The close succession of upper and lower thin, pointed profiles does not allow a smooth, seamless and constantly correct transition from one tooling group to the next one in continuous operation.

As a result of this, the profiled webs that are produced often occur with changes in the distance between individual rows of profiles, these distance transitions having beads, or at least visible seams.

Faulty batches are therefore also not uncommon in continuous operation.

It has been shown that for a flawless, operationally undisturbed, variable in the geometric shape of the profiles to be trained (also called knobs), the considerable 3 REΛ Disadvantages of previously known methods and the manufacture of webs or plates of the aforementioned type that eliminate their products and that require specific process parameters and their interaction, which were first recognized and implemented in the context of the invention.

The invention relates to a

Process for the formation of a plurality of hollow, possibly tapering to the tip, interconnected profiles at the base of a web of material with thermoplastic softening behavior, the material being a tensile force-producing action of the pin-shaped tools guided in the vertical direction to the material plane is exposed, characterized in that the material web is heated to the temperature of sufficient plasticizability shortly before entering the deformation region and then subjected to the action of the step-like, simultaneously vertically and horizontally moving to the material web plane, a temperature considerably lower than that of the material temperature having such tools is suspended, depending on the softening behavior of the material under tension

a) the vertical and horizontal movement of the tools in connection with the web speed of the material from the moment the tools first touch the material surface until the intended final length of the profiles has been reached, that is to say over the entire deformation path subject to the profile-forming tensile force , preferably has a paraboid shape, so that the tool tips asymptotically approach the final length of the profiles, b) the vertical movement of the tools takes the value zero when the final profile formation is reached,

c) the horizontal movement speed of the tools in the region of the deformation section corresponds to the speed of the rectified material web.

d) the variable input angle formed from the material plane as a first leg and the degree of lowering of the tools until the first contact with the web surface is reached as a second leg, the apex of which coincides with the apex of the first contact is

e) the pin-shaped tools remain unchanged until the material has finally hardened with further horizontal movement, when they have reached the final length of the profiles, forming a material cooling and calming zone,

f) the tools are subsequently discharged horizontally and vertically at an exit angle which is considerably greater than the entry angle and returned to the exit of the deformation.

Although the new method was developed primarily for continuous operation for the formation of profiles formed on both sides from the material level, it can also be used for the one-sided formation of profiles. In this case, the material web is guided on one side over a supporting, multi-mesh grid or net or perforated sheet with at least the number of meshes corresponding to the number of profile-forming pin-shaped tools or carried by it, the mesh assuming the movement process of the material web. The profiling tools act on the material to be shaped from top to bottom or from bottom to top.

The size of the deformation section and the penetration speed in relation to the web speed (section of the profile formation, also called the shaping zone) can be varied by the entrance angle (a). The size of the deformation path is a function of the material web thickness and the thickness of the profiled end product obtained or aimed for, the material viscosity at the moment the profile is formed, the tool mass (temperature and weight of the tool, if applicable) and the shape (habit) of the individual profiles. The entry angle (a) should not exceed or fall below a value of 5-45 °, in particular 20-30 °.

The profiles are preferably formed in continuous rows transversely to the material web, these being oriented alternately upwards and downwards in the case of double-sided profile formation, which corresponds to the preferred shape. They can also be offset from one another, have different lengths, or long and less long profiles can be formed alternately individually or in groups. Finally, deviations - even if only to a small extent - from the vertical alignment of the profiles to the material plane are also possible. Although practically all geometrical shapes of the profile-forming tools can be used in the method according to the invention, and there are no restrictive requirements such as in DE-OS 22 58 513, pin-shaped tools of cylindrical configuration with a flat, flat end surface have been found, however outside cross-section proved to be particularly suitable. These tool pins can have a concave shape on the end surfaces, that is to say on the surfaces by which the profile-forming pulling effect is brought about

Have indentation, such as in the shape of a hemisphere or a segment of a circle. Finally, those tool pins are particularly effective, the end regions of which are chamfered on the outermost circumference.

It goes without saying that individual stages of the process can undergo certain changes, operational adjustments or even more appropriate training. So it is e.g. possible instead of an already prefabricated material web, e.g. a film to use an extruder that serves both the production of the starting material web and their heating to the area of sufficient plasticization.

The course of the simultaneous vertical and horizontal movement of the pin-shaped tools from the beginning of the first contact with the plasticized material web to z reaching the outermost profile length, that is to say in the entire area of the so-called deformation zone, corresponds to an inclined plane, which in certain cases has a more parabe-shaped course can assume (if the

Penetration speed should be varied over time) which merges with the continually decreasing vertical movement until the zero point (extreme profile length) reaches the horizontal of the path plane. The course of the simultaneous vertical and horizontal movement of the pin-shaped tools in the deformation zone, whether as an uncurved inclined plane or as a parabolic approach to the zero point of the vertical movement, is a function of the properties of the material to be deformed, in particular its temperature-dependent plasticizing behavior, whereby for highly viscous , only in the narrow temperature range plasticizable materials such as glasses, the parabolic shape appears more favorable, while for low viscosity

Masses such as polyolefins and the like are more likely to be offered by a smooth, non-curved shape course corresponding to the inclined plane.

A precise coordination of the vertical and horizontal movement (speed) of the tools relative to the tool is of decisive importance for a perfect, unhindered and one-sided formation of the profiles from the path of the thermally plasticized material, which is not subject to operational disturbances

Material web, the length of the deformation zone, the length of the cooling and calming zone, the early vertical alignment of the tools perpendicular to the horizontally moving material plane before reaching the first contact, and - to be considered as the material constant of the end product - the distance of the opposing deformation zone when the profile is formed on both sides Tools.

The tools must have assumed their vertical position in relation to the material web plane at the beginning of the material deformation and must not change this during the course of the profile formation until the end of the cooling and calming zone. The vertical movement of the tools within the deformation zone can easily be variable with the maximum speed during the initial contacting the ground and the Material¬ W ^τ ert zero on reaching the outermost profile length (parabeiförmiger course). However, it can also decrease with a constant value, forming the already defined inclined plane, the apex of which, in turn, represents the outermost profile length with the material web plane (zero value).

All movements, i.e. the vertical and horizontal movement of the tools, the movement of the material web, the adjustment of the distance of the tools in the deformation area, the removal of the pins and thus the tools from the profiled path, the return of the tools to the starting point of the deformation and the absolute alignment of the Tools for the material web at the beginning of the shaping process must be infinitely adjustable and adjustable if all the products in accordance with the invention are to be driven and different thicknesses and

Structures are at risk.

If the tools are positioned on circumferential transport elements, care must always be taken that they - as is the case with the device according to the invention - only in the area of the tool alignment perpendicular to the material web, in the deformation zone, in the cooling and calming zone and in the area of the tool removals lie seamlessly against each other while the return transport must have enough play between the tools to allow the early alignment perpendicular to the material web. The new process offers the following advantages, which greatly enrich the application technology as a whole: Both discontinuous and continuous operation are possible, the latter being preferred. The pin-shaped tools - with their carrying elements - can be replaced at any time and continuously. The adjustment of the different movements to each other does not lead to the formation of undesired "seams" between the boundaries of adjacent tools or to incorrect deformation. The tensile pressure to form the profiles from the softened material is only effective in the direction of the profiles. Other pressure influences, which can lead to, for example, expansion of the profile cross-section or even destruction of the profiles during the deformation process, are completely excluded. The fact that the s ift-shaped tools remain in the profiles when they pass through the entire cooling and calming zone has made the formation more stable, more configuration-oriented, more solid

Profiles. The method is practically applicable to all thermally plasticizable materials. This includes the entire class of relevant homo- or copolymeric plastics, such as vinyl polymers and corresponding copolymers, polyolefins, polyamides, polynitriles, polycyanates and methacrylates, synthetic rubber and related products. The method is also applicable to plasticizable cellulose derivatives. Certain glasses, some ceramic materials and even thermally deformable metals and metal alloys are also suitable. Foodstuffs such as foils or plates made of sugar, chocolate and the like can, under certain conditions, also be profiled using the new process. It is understood that the variety of materials is not exhausted with this exemplary list. The length of the profiles, their basic diameter or cross-section, the degree of possible tapering to the tip, the material thickness of the finished profiles, the size (area) of the bond at the base of the profile, the geometric habit, the sequence of profiles of different configurations and length etc. can be varied as desired by the type of pin-shaped tools, the depth of drawing of the pin-shaped tools, the distance of the tools facing each other in the deformation zone, the length of the deformation zone and the thickness of the thermally plasticizable material fed in.

This results in a large number of possible profile configurations or profiled finished material webs which can be used in almost all areas of technology.

The method is explained in more detail below, reference being made to a device which has proven to be particularly suitable for carrying out the method.

The figures used to describe the method and the manner of operation and structure of the device show:

1, the overall system consists of a roll removal (1) for the deformable film or sheet made of thermally plasticizable material, a device (2) for heating the material in or above the plasticizing area, the actual shaping device

(3), consisting of - not visible - tool alignment zone, deformation zone and cooling and calming zone, the common machine drive with gears (8), roller mill (4) and product acceptance table (5), which is also set up as a cutting station for the extraction of plates can be. It goes without saying that the roll take-off (1), the heating device (2), the roller mill (4) or the take-off table (5) can be of any type. For example, the material can be pre-formed directly from an extruder, and the roll removal (1) can be dispensed with. A glass furnace can also be connected directly upstream of the machine (3) when processing glasses etc. These design options belong to the general technical knowledge of the person skilled in the art and depend on the type of material to be processed.

It has proven to be expedient to switch on a further roller system (possibly heated) between the heating device (2) and the actual shaping (3) for the level alignment of the material web.

1 further shows the arrangement of the vertically aligned movement elements (9) guided in a circle with a vertical axis, the jointly driven ends of the height and depth adjustable spindles (10), the box-shaped or plate-shaped support bodies (6, 6 ') to hold the pin-shaped tools, driver rings (11) and the four-fold arranged truncated cylinder-shaped bolts or cams (7) which extend beyond the material web on both sides and in which the in particular rod-shaped movement elements (9) engage. The speed of the drive rings (11), the speed of the movement elements (9) and the height adjustment of the spindles (10) can be changed as desired and adapted to the material web or its passage speed by means of the interacting, continuously variable transmission (8) , it is advantageous to drive the driver rings (11) which grip the tool carriers in the driver area with a slightly increased force in order to achieve a seamless pressing of the tools.

As can also be seen from FIG. 1, the tools are packed close together in the area of shaping and cooling or calming, so that a transition-free profile is formed. At the moment of withdrawal, i.e. the exit from the solidified profiles, the distance between the tools or the tool support body (6, 6 ') increases, they are gripped by the driver rings (11) and returned to the material inlet with the fastest return movement. Before the driver rings (11) are reached, the tool carrier bodies (6, 6 ') naturally leave the area of influence of the vertical movement elements (9).

The system shown in Fig. 2 corresponds to that according to Fig.l. A detailed page layout and a top view is shown, which is also a device for forming profiles from the material web on both sides. As can be seen, the supporting bodies (6,6 ') are guided in a circle over upper and lower running rails (7,7'), the material web being held under the influence of the pin-shaped tools held against one another on the supporting bodies (6,6 ') moved in the horizontal plane (from right to left in the system shown). 2 shows the area of the tool alignment zone (D) - alignment in the vertical and formation of a tight, gap-free association with one another - the actual shaping one (A), the cooling and calming zone (B) and - not designated - the tool removal zone at the left end of the machine (3). Rod-shaped movement elements (9) on each side of the machine (3) determine the exact (vertical) positioning of the tool carrier bodies (6, 6 ') in cooperation with the driver rings (11. Running with increased force and having a slip clutch) ) and capture them as soon as they have been pushed up by the driver rings, which on the guide piece 30 acc. Fig. 8 attack.

As already mentioned, the distance between the tools in the shaping area (A) can be adjusted via the spindles (10). This also makes the depth of the profile formation variable, regardless of the length of the pin-shaped tools. This means that profiles with a shorter length (than the tool) can also be formed with a tool of a certain length.

It is even possible to change the distance between the tools during the shaping process via the spindles (10) so that rows of profiles with large and small lengths can alternate with unchanged tool length.

Finally, Fig. 2 shows that with the help of the spindles (10), the length of the shaping zone (A) itself, and the entry angle between the upper and lower tool path can be changed. This measure is always necessary if the material to be deformed, for example, requires an extremely long shaping zone (A) due to its temperature-dependent viscosity or plasticizing behavior, or the tools in (D) aligned perpendicular to the material web are very careful, ie with reduced dimensions Tensile force should act on the material. 3 shows a more schematic illustration of the processes within a machine with profile formation on both sides from the thermally softened material web (16).

After the quick return of the tool carrier body

(6,6 ') from the (left) machine end for renewed action on the material web, they are first positioned with the help of the rod-shaped movement duck (9), see FIGS. 1 and 2, with simultaneous horizontal and vertical movement perpendicular to the material web (zone D) and then enter the shaping zone (A) at (A ¹ ). In this, the pulling effect for forming the profiles (22) runs asymptotically until the vertical movement has reached zero in the transition to (B). After solidification in the cooling and calming zone (B), the tools (pins 12, 12 ') are lifted off, the exit angle (b) described here being considerably larger than the entrance angle (a) (FIG. 4) .

Within the shaping zone (A), the course of movement of the tools can resemble an uncurved inclined plane, but it can also have a parabolic character (FIG. 5).

Fig. 6 shows in section the position of the opposing tool carrying body (6) and the pin-shaped tools (12) during or at the end of the shaping process. The material level (16) is practically no longer available. The pulling effect of the pins has resulted in an even profile (20). In the top view, the path offers itself as a sequence of upward (17) and downward (18) profiles (FIG. 7). A preferred embodiment of a tool support body (6) with an inserted comb-shaped set of pin-shaped tools (12) is shown in FIG. 8. The support element ends in a pin or bearing (30)

Driving cams (31), which are held by the running rails (7, 7 '), see Fig. 2, and, clamped in positive paths in the disposal zone, ensure that the tools are raised and lowered correctly in accordance with the method. Tool fastening elements (33) in the lower frame area (32) of the carrying elements (6) are designed in such a way that they allow easy replacement of the pin-shaped tools (12).

Fig. 9 shows a somewhat modified form of the tool carrying elements (6). In this case, a set of pin-shaped tools is fastened centrally at (34) in the frame area (32).

The end plates (24) of the tool support body (6) carry cam-like or bolt-shaped elements (25, 26, 27, 28) arranged in a square shape to one another according to FIGS. 10 and 11, between which the rod-shaped movement elements (9), cf. . 2, intervene and thus effect the horizontal transport and the vertical alignment of the pin-shaped tools.

Another embodiment of the end plates (24) completely covers the supporting bodies (6) according to FIGS. 12 and 13, and the comb-shaped set of pin-shaped tools (12) shown is also partially covered by the end plates (24).

By tapering (29) in the carrying bodies (6), which act as a kind of Bayonnet closure, the tools snap into place and cannot be pushed out to the side. An increased vertical distance between top

5 (25.26) and lower (27.28) bolt-shaped elements simultaneously leads to improved stability between the support body end plate (6) and the rod-shaped movement element (9) used in each case, see FIG. 2. Also with this type of end plates the

10 length of the rod-shaped movement elements (9) can be reduced.

14 shows exemplary possibilities for the formation of a predetermined and defined profile length (= thickness (s) of the finished material web obtained which is profiled on both sides) depending on the length of the deformation zone with the same material and the same length of the pin-shaped tools.

20 The product according to Fig. 14 a requires e.g. for one

Product thickness of (e) = 100 mm, a deformation distance of (f) = approx. 800 mm. With decreasing product strength e.g. to (e) = 50 mm (Fig. 14 b) the length of the deformation path is reduced to (f) = 400 mm, it becomes

25 thus 50% shorter. This already gives a mathematical relationship between product strength (e) and the length of the deformation section (f), but the material properties (viscosity, temperature range of the plasticization, thermal stability of the material)

30 etc.) occur as changing variants.

The further course of the decreasing product thickness (e) to 25 mm (FIG. 14 c) reduces the deformation distance (f) 200 mm and finally, according to FIG. 14 d, only 100 mm of deformation path (f) are required for a product thickness of approx. 4 mm.

This process, which is shown here by way of example, was determined using the same tools with profile formation on both sides of polyurethane copolymers, a continuous process based on a web width of 1000 mm being used.

The change or adaptation of the deformation distance (f in FIG. 14) can be carried out by adjusting the opposing tools with the aid of the spindles of the machine, as a result of which the distance between the pin-shaped tools which have not changed in length has been varied. But it is also possible to replace the guide pieces.

Finally, reference should be made to a particularly favorable type of pen-shaped tools, as are shown schematically in FIG. 15.

6, depending on the material used, it can sometimes be advantageous to make the flat ends hemispherical or bowl-shaped concave towards the inside (Fig. 15 a). As a result, less cold mass is brought into contact with (solidification) the material to be plasticized when it first comes into contact with the cold pins, so that the pulling effect favors the stability of the profiles during the deformation process. A solidification bead is avoided. 15 b shows a different shape of the pin ends, whereby the beveling prevents the plastic material film at the tip of the pin-shaped tool from being torn off from time to time.

Such pin-shaped tools have optimal properties, the ends of which according to FIG. 15 c have both a bevel according to FIG. 15 b and a concave end surface formation according to FIG. 15 a. This configuration virtually eliminates defects in the material during the profile formation and in the course of the deformation and subsequent consolidation process.
