[0124] FIG. 6 schematically shows a model view of a system in the form of a shaping, filling and sealing system in which a shaped film is again moved along a crystallization line in the machine direction outside of a molding tool to at least in part crystallize the film material along the crystallization line; and

[0125] FIG. 7 schematically shows a model view of a different system having a rotary table in which a shaped film is moved along a crystallization line in the machine direction outside of a molding tool to at least in part crystallize the film material along the crystallization line.

[0126] FIG. 1 shows, in a first embodiment, a device 1 for shaping, in particular for thermoforming, a film 2 made of a thermoplastic film material (not specifically designated), the film 2 being transported through the device 1 along the processing line 4 in the machine direction 3. The film 2 is unwound from a coil 5 here. The processing line 4 is linear and straight in design here. A CPET material is used as a thermoplastic film material here.

[0127] In this embodiment, the device 1 comprises a shaping tool 8 having an incoming shaping region 9 as well as an outgoing shaping region 10 arranged farther downstream to shape the film 2 into shaped pieces 11 and finally into finished products 12.

[0128] In the present case, the incoming shaping region 9 and the outgoing shaping region 10 form an overall processing surface (not designated again) of the shaping tool 8, at least with regard to the shaping of the shaped pieces 11 or the finished products 12.

[0129] Furthermore, the device 1 comprises a crystallization line 15 on which the thermoplastic material of the shaped film 2 can completely crystallize.

[0130] In this embodiment, the crystallization line 15 is arranged between the incoming shaping region 9 and the outgoing shaping region 10 and extends in the machine direction 3.

[0131] Furthermore, the crystallization line 15 is a partial line (not specifically designated) of the processing line 4 and can be designed to have almost any length within the processing line 4.

[0132] The crystallization line 15 is at least the size of the incoming shaping region 9 in the machine direction 3.

[0133] In this case, a crystallization process is initiated by the shaping of the film 2 in the incoming shaping region 9 and continued on the crystallization line 15, it being possible to subsequently complete the crystallization process in the outgoing shaping region 10.

[0134] The crystallization line 15 makes it possible to move the crystallization out of the incoming shaping region 9 in particular, as a result of which the closing time of the shaping tool 8 can be significantly reduced. As a result, a higher cycle rate can be achieved with the device 1 when shaping the film 2.

[0135] Furthermore, the crystallization process can overall be influenced in a greater variety of ways by means of the crystallization line 15, for example by being able to additionally heat and/or cool the crystallization line 15, in particular as a function of the choice of thermoplastic material and/or the film to be processed, for example with regard to the film thickness.

[0136] FIG. 2 shows a further embodiment of a device 101 for shaping, in particular for thermoforming, a film 102 made of a thermoplastic film material to form a shaped piece 111 or a finished piece 112 having a shaping tool 108. A CPET material is also used as a thermoplastic film material here.

[0137] The shaping tool 108 has an incoming shaping region 109 and an outgoing shaping region 110 that comprise an incoming shaping cavity 109A as well as an outgoing shaping cavity 110A.

[0138] In this embodiment, the special feature of the shaping tool 108 can be seen in that both the incoming shaping region 109 and the outgoing shaping region 110 can be heated such that the shaping cavities 109A and 110A available for shaping the film 102 are doubled on the shaping tool 108.

[0139] In this respect, the overall processing surface 108A present in the shaping tool 108, by means of which overall processing surface the film 102 can be processed, can also be heated.

[0140] The film 102 is transported through the device 101 in the machine direction 103 along a linear and straight processing line 104. The film 102 is again unwound from a coil 105 here.

[0141] An additional heating device 117 is placed upstream of the shaping tool 108 to preheat the film 102 before it is shaped with the shaping tool 108.

[0142] A crystallization line 115 is integrated into the actual processing line 104 downstream of the shaping tool 108, on which crystallization line the thermoplastic material can crystallize after being shaped. The crystallization line 115 can be designed to have almost any length here.

[0143] A further molding tool 118 is arranged further downstream, in which molding tool the film 102 or the shaped piece 11 can subsequently be finally shaped.

[0144] In this respect, the shaping tool 108 represents a primary molding tool 119 and the further shaping tool 118 represents a secondary molding tool 120 for the purposes of the present invention.

[0145] The degree of crystallization of the thermoplastic film material can be controlled by means of the further molding tool 118 or the secondary molding tool 120, it being possible to actively cool the secondary molding tool 120.

[0146] This also means that, in this embodiment, the shaping tool 108 can be heated upstream of the crystallization line 115 and a further molding tool 118 can be cooled downstream of the crystallization line 115.

[0147] Furthermore, the crystallization line 115 can be heated and/or cooled at least in certain regions here, as a result of which the crystallization process taking place on the crystallization line 115 can additionally be manipulated.

[0148] A punching and stacking device 123 is provided at the end 122 of the processing line 104, at which punching and stacking device the finished products 112 can be punched out and subsequently stacked.

[0149] FIG. 3 shows a different embodiment having a system 225 for producing products 212 from a thermoplastic film material, in particular a CPET material, the products 212 being formed from a film 202 that is unwound from a coil 205 and transported through the system 225 in the machine direction 203 along a processing line 204.

[0150] The system 225 is in particular characterized by a first shaping station 226 having a first molding tool 208, a further shaping station 227 having a further molding tool 218 as well as a crystallization line 215 arranged between the first shaping station 226 and the further shaping station 227.

[0151] To be more precise, the first shaping station 226 is placed in an input region 228 of the crystallization line 215 and the further shaping station 227 is placed in an output region 229.

[0152] Accordingly, the first molding tool 208 of the first shaping station 226 embodies a primary molding tool 219 of the system 225 and the further molding tool 218 of the further shaping station 227 embodies a secondary molding tool 220 of the system 225.

[0153] The crystallization line 215 can be designed to have almost any length here. In any case, this crystallization line 215 is also configured to continue a crystallization process initiated at the first shaping station 226 as a main crystallization having all the advantages described here, preferably into the further shaping station 227, where the crystallization process can then be completed.

[0154] Furthermore, the system 225 also comprises a heating station 230 by means of which the film 202 can be preheated upstream of the first shaping station 226 before it is shaped into shaped pieces 211 or into the finished products 212.

[0155] A steel strip punch station 231 is arranged farther downstream and after the further shaping station 227, by means of which steel strip punch station the products 212 can be punched out of the film 202.

[0156] FIG. 4 shows a further embodiment having an alternative system 325 for producing products 312 from a thermoplastic material, in particular a CPET material.

[0157] In this case, the products 312 are formed from a film 302, the film 302 being unwound from a coil 305 and subsequently being transported through the system 325 in the machine direction 303 along a processing line 304.

[0158] The system 325 also has, in particular, a first shaping station 326 having a first molding tool 308 and a further shaping station 327 having a further molding tool 318.

[0159] A crystallization line 315 is again arranged between the first shaping station 326 and the further shaping station 327, the first shaping station 326 being placed in an input region 328 of the crystallization line 315 and the further shaping station 327 being placed in an output region 329.

[0160] Accordingly, the first molding tool 308 of the first shaping station 326 embodies a primary molding tool 319 of the system 325 and the further molding tool 318 of the further shaping station 327 embodies a secondary molding tool 320 of the system 325.

[0161] The crystallization line 315 can be designed to have almost any length here and this crystallization line 315 is configured to continue a crystallization process initiated at the first shaping station 326 as a main crystallization having all the advantages described here, preferably into the further shaping station 327, where the crystallization process can then in turn be completed.

[0162] The system 325 also has a heating station 330 by means of which the film 302 can be preheated upstream of the first shaping station 326 before it is shaped into shaped pieces 311 or into the finished products 312.

[0163] A punching/stacking station 332 is also arranged after the further shaping station 327, by means of which punching/stacking station the finished products 312 can be punched out of the film 302 and subsequently stacked.

[0164] The embodiment illustrated in FIG. 5 also shows a system 425 by means of which products 412 can be produced from a thermoplastic film material, in particular a CPET material.

[0165] The products 412 are formed from a film 402 here. For this purpose, the film 402 is unwound from a coil 405 and the film 402 is subsequently transported through the system 425 in the machine direction 403 along a processing line 404.

[0166] This system 425 also uses, in particular, a first shaping station 426 having a first molding tool 408 and a further shaping station 427 having a further molding tool 418 between which a crystallization line 415 is placed.

[0167] In this case, the further shaping station 426 is not only equipped with the further molding tool 418 but is simultaneously provided with a punch (not explicitly shown and designated). In this respect, the further shaping station 426 is a steel strip shaping and punching station 435 that is located at the end of the crystallization line 415.

[0168] While the first shaping station 426 is in an input region 428 of the crystallization line 415, the further shaping station 427 or the steel strip shaping and punching station 435 is, in this respect, placed in an output region 429 of the crystallization 415.

[0169] Accordingly, the first molding tool 408 of the first shaping station 426 embodies a primary molding tool 419 of the system 425 and the further molding tool 418 of the further shaping station 427 embodies a secondary molding tool 420 of the system 425.

[0170] The crystallization line 415 can also be designed to have almost any length in this embodiment.

[0171] In this case, this crystallization line 415 is also once again configured to continue a crystallization process initiated at the first shaping station 426 as a main crystallization having all the advantages described here, preferably into the further shaping station 427, where the crystallization process can then in turn be completed.

[0172] A heating station 430 is arranged on the system 425 before the shaping station 426, by means of which heating station the film 402 can be preheated upstream of the first shaping station 426 before they are shaped into shaped pieces 411 or into the finished products 412.

[0173] Following the further shaping station 427 or the steel strip shaping and punching station 435, the finished products 412 are stacked to form a stack of products 436.

[0174] FIG. 6 shows an additional embodiment of a shaping, filling and sealing system 525 by means of which products 512 can be produced from a thermoplastic film material, in particular a CPET material. In this case, the products 512 are also formed from a film 502 that is unwound from a coil 505. The film 502 is then transported through the shaping, filling and scaling system 525 in the machine direction 503 along a processing line 504, the processing line 504 being of rectilinear design. In this respect, the film 502 is also transported through the shaping, filling and sealing system 525 in a translational manner in the machine direction 503 in this embodiment.

[0175] The processing line 504 comprises a crystallization line 515 on a partial portion (not designated again), which crystallization line is of rectilinear design, exactly as in the case of the systems 225, 335 and 425 already explained above.

[0176] A first shaping station 526 is arranged in an input region 528 of the crystallization line 512 and a further shaping station 527 is arranged on the crystallization line 515 in an output region 529 of the crystallization line 515.

[0177] The first shaping station 526 comprises a first molding tool 508 that, in this respect, embodies a primary molding tool 519 of the system 525.

[0178] Accordingly, the further shaping station 527 comprises a further molding tool 518 that represents a secondary molding tool 520 of the system 525.

[0179] In this further embodiment having the shaping, filling and scaling system 525, the crystallization line 515 can also be designed to have almost any length to continue a crystallization process initiated at the first shaping station 526 as a main crystallization on the crystallization line 515, it being possible for this main crystallization to take place into the further shaping station 525, at which the crystallization process can then finally be completed.

[0180] In a manner similar to the systems 225, 325 and 425 described above, the shaping, filling and sealing system 525 also has a heating station 530 by means of which the film 502 can be preheated upstream of the first shaping station 526 before the film 502 is then shaped into shaped pieces 512 or into the finished products 512 with the aid of the primary molding tool 519.

[0181] A filling station 540, a sealing station 541 and a separating station 542 are located farther downstream on the processing line 504 in the machine direction 503 after the second shaping station 527 having the secondary molding tool 520 such that the products 512 hitherto produced with the shaping, filling and sealing system 525 can subsequently be filled with almost any filling material 543 at the same time.

[0182] Even farther downstream, the sealing station 541 is located after the filling station 540, by means of which sealing station the products 512 filled with the respective filling material 543 can then be sealed with a sealing film 544.

[0183] In this embodiment, the sealing film 544 is wound onto a supply roll 545 and is applied to the respective product 512 after being unwound from said supply roll 545 and placed onto the filled products 512 by means of a sealing unit 546, namely with a sealing movement 547 transverse to the machine direction 503.

[0184] The products 512 thermoformed, filled and sealed in this manner are then separated at the end of the processing line 548 by means of the separating station 542 such that ready-to-use packaging units (not designated here) are ultimately present at the end of the processing line 504.

[0185] In this respect, the embodiment illustrated in FIG. 6 shows by way of example how a unit composed of a filling station 540, a sealing station 541 and a separating station 542 can be combined with the present crystallization line 515, it being unnecessary to discuss the individual design of the filling station 540, the sealing station 541 and the separating station 542 in further detail in the present case because they are widely known in terms of designs and methods.

[0186] FIG. 7 shows, once again by way of example, a different embodiment in the form of a rotary table system 625 for producing products 612 from a thermoplastic film material in the form of a film 602, the thermoplastic film material being a CPET material. In this case, the film 602 is again unwound from a coil 605 and subsequently prefabricated to form individual blanks 651 by means of a blanking unit 650.

[0187] These prefabricated blanks 651 are then transferred to a rotary table 655 in the machine direction 603, which rotary table rotates about an axis of rotation 656. The machine direction 603 is thus not only of rectilinear design, as is the case with the systems 225, 325, 425 and 525 described above, but it also has a circular component (not shown and designated again here) such that a processing line 604 accordingly also has a curved partial portion 658.

[0188] When the rotary table 655 is rotated in the direction of rotation 657, the separated blanks 651 successively reach the individual processing stations of the rotary table system 625, such as a heating station 630, a first shaping station 626 having a first molding tool 608 or having a primary molding tool 619, a second shaping station 627 having a further molding tool 618 or a secondary molding tool 620, and a discharge station 660.

[0189] At this point, it should also be noted that the second shaping station 627 can optionally also be designed as a steel strip shaping and punching station (not explicitly designated here), as is explained, for example, with regard to the embodiment of FIG. 5. In such an optional embodiment, the products 612 can then optionally simultaneously be stacked at the discharge station 660.

[0190] In any case, a crystallization line 615 is again located between the first shaping station 626 and the second shaping station 627 such that the first shaping station 626 is located in an input region 628 of the crystallization line 615 and the second shaping station 627 is arranged in an output region 629 of the crystallization line 615 accordingly.

[0191] The crystallization line 615 is designed to be curved or bent on the rotary table 655. In any case, the crystallization line 615 is part of the aforementioned curved partial portion 658 of the processing line 604.

[0192] With regard to the rotary table system 625 for producing products 612, it should furthermore be noted that the film 602 or the separated blanks 651 are transported to the individual processing stations 630, 626, 627 and 660 and also to the crystallization line 615 by means of the rotary table 655.

[0193] In this case, the number of processing stations can vary depending on the product requirements and on crystallization line 615.

[0194] It is clear that the film 602 or the separated blanks 651 can also be preheated outside of the rotary table 655.

[0195] In any case, the rotary table system 625 illustrates a system of a shorter and very compact design for producing products from a thermoplastic film material for the purposes of the present invention.

[0196] At this point, it should explicitly be pointed out that the features of the solutions described above or in the claims and/or figures can optionally also be combined to implement or achieve the described features, effects and advantages in a correspondingly cumulative manner.

[0197] It is clear that the embodiments described above are merely initial designs of the invention. In this respect, the design of the invention is not limited to these embodiments.
