Manufacturing plant for producing a door for a household refrigeration appliance, and method for producing the door

Description

[0001] One aspect of the invention relates to a manufacturing system for producing a door for a household refrigerator. The manufacturing system comprises at least one mold. The mold has a first mold carrier, which is designed to receive the front of the door. The mold also has a second mold carrier, separate from the first, which is designed to receive the back of the door. Furthermore, the mold has a hinge device by which the two mold carriers are pivotably connected to each other. This allows the mold to be opened and closed. In the open state, the first and second mold carriers are accessible to insert the front and back of the door, respectively. The front and back of the door are pre-manufactured components.They are inserted into the mold carriers accordingly.

[0002] Such manufacturing systems for producing doors of a household refrigerator, in which a thermally insulating material is incorporated, are known in various embodiments. For example, so-called drum systems are known as manufacturing stations in this context. As the name suggests, a drum system has a drum on which several separate manufacturing molds are arranged. The drum can rotate about a horizontally oriented axis, so that the manufacturing molds also rotate accordingly.

[0003] In Fig. 1In this context, a manufacturing form 2' known from the prior art for a drum system is shown as manufacturing system 1'. This manufacturing form has a first mold carrier 3. It has a separate second mold carrier 4'. Furthermore, a hinge device 5' is shown. In the vertical y-direction of manufacturing system 1' and thus also of manufacturing form 2', these two mold carriers 3' and 4' are arranged one above the other. Fig. 1The assembly position is shown when the drum of the production system 1' is rotated such that a worker 6, while standing, has access to this lower second mold carrier 4'. The production mold 2' remains in this assembly position. As can be seen, the worker 6 can then relatively easily load the lower second mold carrier 4', which is facing him and inclined at an angle, with a back panel 7' for the door. This back panel 7' of the door is made of plastic.

[0004] Furthermore, in Fig. 2As can be seen, with this arrangement of the manufacturing form 2', loading the first mold carrier 3' located above it is ergonomically very difficult and time-consuming for the operator 6. On the one hand, access from above is restricted because the second mold carrier 4' below is positioned accordingly, pointing forward. In this context, it is therefore also difficult to load the front panel 8 of the door onto the upper first mold carrier 3'. Consequently, in this embodiment, it can happen that the front panel 8 is not positioned with sufficient accuracy. This can have disadvantages when closing the manufacturing form 2'.In particular, the front 8' and the back 7' may not be positioned relative to each other in such a way that the thermal insulation material is introduced effectively and correctly, and that no unwanted foam escapes when the manufacturing form 2' is closed.

[0005] In Fig. 3 In this context, a further embodiment of such a production plant 1' from the prior art is shown. To further illustrate this, Fig. 2To reduce the disadvantages described above, in one embodiment of a corresponding production plant 1' in the form of a drum system, the lower, second mold carrier 4' is pivotable downwards as indicated by arrow P. The upper mold carrier 3' remains in its original position. This pivoting action provides improved access to the upper, first mold carrier 3'. However, it still requires the operator 6 to work overhead to load the front 8' onto this first, upper mold carrier 3'. Furthermore, pivoting this second, lower mold carrier 4' downwards requires a corresponding amount of time.

[0006] Therefore, production plant 1' not only exhibits problems regarding the position of the mold carriers 3' and 4' relative to each other, but also results in an increase in cycle time during door production, since no activity can take place during the phase in which the lower mold carrier 4' is pivoted downwards. This therefore represents a corresponding loss of time.

[0007] In view of the disadvantages of such a manufacturing plant 1' explained above, the object of the present invention is to create a manufacturing plant in which the manufacturing time of a door can be reduced precisely in the manufacturing phase in which the manufacturing mold is to be loaded.

[0008] This task is solved by a manufacturing plant and a process in accordance with the independent claims.

[0009] US 3,139,369 A discloses a device for manufacturing laminated building panels with surface plates and spacers bonded between the plates, comprising means for moving the surface plates, means for applying a coating of a foamable, adhesive cellular plastic to the tops of the surface plates, means for providing spacers, and means for pivoting the surface plates about adjacent edges of the surface plates.

[0010] DE 11 47 029 B discloses a method for producing plastic composite bodies consisting of cover layers and foam cores, in which a foam core is produced in a space between two support forms, wherein at least one form is lined with a plastic film formed by vacuum drawing and optionally provided with adhesives and reinforcing layers, which is intended to serve as a cover layer for the composite body.

[0011] JP H06 278224 A discloses a method for manufacturing a plastic container, wherein a first sheet-like molten resin extruded from an extruder is formed under pressure through a first rear surface shape and a first top surface shape into a predetermined shape, and a second sheet-like molten resin extruded from the extruder is formed under pressure through a second rear surface shape and a second top surface shape into a predetermined shape.

[0012] Against this background, the invention relates to a manufacturing plant with the features of claim 1 and a method according to claim 15. Further preferred embodiments are defined in the dependent claims.

[0013] One aspect of the invention relates to a manufacturing plant for producing a door for a household refrigerator. The manufacturing plant is thus a door manufacturing plant for producing a household refrigerator door. In particular, the manufacturing plant is also a foaming plant in which thermal insulation material can be introduced into a manufacturing mold, in which a front and a back of the door are inserted, into a space between the front and back of the door.

[0014] The manufacturing system includes at least one mold for receiving a front and a back panel of the door. The mold is designed so that the front and back panels are inserted into it as pre-fabricated components. The mold comprises a first mold carrier. The first mold carrier is designed to receive a pre-fabricated front panel of the door. The mold also includes a second mold carrier, separate from the first. This second mold carrier is designed to receive a pre-fabricated back panel of the door. Furthermore, the mold includes a hinge mechanism. The two mold carriers are directly connected to this hinge mechanism, in particular by pivoting them together. This design allows the mold to be opened and closed.In the closed position, the mold carriers lie on top of each other. In the open position, the mold carriers are positioned so that the assembly areas, into which the front and back of the door can be inserted, are freely accessible. The mold carriers are, in particular, the mold halves of the manufacturing mold.

[0015] The manufacturing mold has a horizontally oriented longitudinal axis. When the mold is open, and viewed along this horizontal axis, the first mold carrier is arranged in line with the second. The hinge mechanism is positioned between these two mold carriers, also along this horizontal axis. The hinge mechanism is arranged such that it forms a pivot axis perpendicular to the horizontal. This type of manufacturing system offers numerous advantages. Firstly, when open, the two mold carriers are virtually at the same height. This allows them to be positioned side-by-side for simultaneous loading.Furthermore, this horizontal position, in which they are arranged in a row, is advantageous in that a worker no longer has to work overhead. Both mold carriers are positioned, or can be positioned, simultaneously so that they can be loaded by a worker or a robot without having to work overhead. This arrangement and design of the manufacturing mold also advantageously achieves the elimination of cycle time losses, as are typically found in the prior art. Fig. 3The previously explained procedure is no longer necessary. This is because it is no longer required that a lower mold carrier, which is no longer present in this manufacturing system according to the invention and the corresponding manufacturing mold, must first be separately pivoted downwards to achieve improved access to a mold carrier arranged vertically above it. Since this principle of a lower and an upper mold carrier in the manufacturing mold is eliminated by the manufacturing system according to the invention, the following can be further refined: Figs. 1 to 3 The disadvantages described above will be completely resolved.

[0016] This concept also allows the two mold carriers to be arranged side-by-side in the same plane and horizontally when the manufacturing mold is open. This enhances the advantages mentioned above. In particular, it enables particularly easy loading. Simultaneous loading is thus made especially simple.

[0017] Furthermore, this orientation also facilitates easy closing of the mold. The correspondingly oriented pivot axis enables a variety of devices to achieve quick and precise closing of the mold.

[0018] In one embodiment, viewed in the vertical direction of the production plant, the first mold carrier and the second mold carrier are arranged at the same height relative to each other when the production mold is open.

[0019] In one embodiment, a mold carrier is oriented at an angle when the manufacturing mold is open and a loading position of the manufacturing mold is reached in the production system. This means that the mold carrier is tilted towards the robot or the operator. In particular, an end of this mold carrier closer to the robot or operator is therefore lower in the vertical direction than an end of the mold carrier farther away from the robot or operator.

[0020] Tilting is not necessary when using a robot. However, it can still be done.

[0021] In one embodiment, it is particularly evident that, when the mold is open and in the assembly position reached along the production line, both mold carriers simultaneously assume the same corresponding inclined position. This further enhances the aforementioned advantages regarding fast, simultaneous, and ergonomically simple assembly.

[0022] In one embodiment, the joint device has an upper joint and a lower joint when viewed in the direction of the pivot axis. These two joints are arranged at opposite corners of the mold carriers. In particular, these are corners of opposite short sides of the mold carriers.

[0023] According to the invention, both mold carriers are essentially rectangular on their respective assembly sides, or are formed as cuboids. The shorter sides of these rectangles are oriented parallel to the pivot axis. They are arranged one after the other along this horizontal longitudinal axis and facing each other. The longer sides of these rectangular mold carriers are oriented in the direction of the horizontal longitudinal axis and are therefore parallel to it. The longer sides of this mold carrier are thus arranged in a row along this horizontal longitudinal axis.

[0024] This also characterizes the geometry of a form carrier specified in this regard with respect to its position in space. In particular, both form carriers are arranged accordingly.

[0025] In one embodiment, the production system includes a conveyor. The two mold carriers are arranged side-by-side on this conveyor in a common plane when the production mold is open. The conveyor may have a corresponding frame. For example, this frame may also include a pivoting device with a horizontal pivot axis. This pivot axis may be oriented parallel to the horizontal longitudinal axis. This pivot axis allows the conveyor to be tilted, enabling the advantageous inclined position of the two mold carriers in the loading position of the production mold, as mentioned above. This pivot axis of the conveyor is, in particular, oriented perpendicular to the pivot axis of the hinged device.

[0026] In one embodiment, the conveying device has a support table.

[0027] The mold carriers are arranged on this support table when the mold is open and the loading position of the mold is reached along the production line. In one embodiment, the support table is inclined at an angle between 20° and 70°, particularly between 30° and 60°, relative to the horizontal plane. This applies especially when the mold has reached the loading position along its path in the production line.

[0028] This tilt is in particular the one already explained above, which is inclined towards a worker or robot standing in front of it.

[0029] In one embodiment, the conveying system includes a conveying unit. The conveying unit allows the mold carriers to be moved along a support table of the conveying system. On the one hand, the mold can thus be moved by the conveying unit into the loading position along the production path in the manufacturing plant. On the other hand, the mold can then be moved from this loading position to the next position.

[0030] In particular, a high degree of automation is not only enabled by this design. The aforementioned aspect of the manufacturing system according to the invention, with its specific arrangement and orientation of the manufacturing mold in the open state, enables a high degree of automation. This is because, as already explained above, access to the individual mold carriers is easily facilitated, both mold carriers are accessible and can be loaded simultaneously, and thus, in particular, loading with a robot, at least of one mold carrier, can be improved.

[0031] In one embodiment, the conveying unit has a rack. This rack is designed for meshing coupling and decoupling with another toothed element of the conveying device. In the meshing state between the rack and the toothed element, a relative movement between the rack and the toothed element can be effected by a motor of the conveying device. This allows the movement of at least one mold carrier, and in particular both mold carriers, along a defined horizontal distance in the direction of the aforementioned horizontal longitudinal axis on the support table to be achieved with exceptional precision. This movement is then slip-free. The corresponding displacement can therefore be carried out very quickly and without slippage or the like. This enables the rapid and precise transfer of the production mold to this loading position along the production path in the manufacturing plant.In particular, compared to an embodiment in which such a toothing device is not present, such positional tolerances of the shape, which could occur due to undesired further rolling or sliding of corresponding rolling or sliding devices, can thus be avoided.

[0032] The required positional tolerances can also be achieved in variants without a rack and pinion system if the acceleration forces are below the prevailing frictional forces on rollers or the transport rollers of a roller device.

[0033] In one embodiment, the conveying unit has a roller assembly on which at least one manufacturing mold rests. Moving this manufacturing mold along the support table by rolling it is therefore easily accomplished. For example, when the manufacturing mold is closed, and especially when the thermal insulation material has already been inserted, this closed manufacturing mold can be easily moved out of the loading position, and this is facilitated by the roller assembly. This additional manufacturing path eliminates the need for a toothed device, as advantageously explained above. Thus, it is advantageous that the movement to reach the loading position of this manufacturing mold is achieved at least by means of the aforementioned toothed device.Following this manufacturing process step, movement based on such a toothed device may then be unnecessary. The aforementioned roller device may then suffice.

[0034] In one embodiment, the production system includes a pivoting device. This pivoting device enables the closing of the production mold. Starting from the open state of the production mold and with the two mold carriers positioned horizontally next to each other, the closing action can be selectively effected by this pivoting device. Specifically, this pivoting device pivots one mold carrier onto the other mold carrier about the aforementioned pivot axis of the hinge mechanism. Such a pivoting device can be designed in various ways. It can incorporate lifting mechanisms of hydraulic, pneumatic, or electric motor operation. However, other pivoting devices are also possible.

[0035] For example, arms can be provided that are combined with a deflection roller, so that when the open manufacturing mold is guided along the manufacturing path in the manufacturing plant, this open manufacturing mold reaches these arms, couples with them, and in particular, due to the existing deflection roller or guide roller, the closing process of the mold carriers around the pivot axis of the joint device is then automatically effected.

[0036] In another embodiment, at least one form carrier has a width, measured parallel to the pivot axis of the hinge device, that is between 750 mm and 1050 mm, in particular between 800 mm and 1000 mm. This design makes it possible to manufacture even very large doors for very large household refrigerators simply and with reduced production time.

[0037] In one embodiment, a mold carrier has a length parallel to the horizontal longitudinal axis, which is particularly between 1200 mm and 2500 mm. The advantages mentioned above regarding width also apply in this respect.

[0038] In another embodiment, the production system includes a foaming unit. This unit is designed to introduce thermal insulation material, in particular thermal insulation foam, into the production mold. Specifically, this thermally insulating foam is injected into the front of the door and / or the back of the door, which is inserted into the mold carrier. This space is formed when the front and back are inserted into the mold carrier and the production mold is closed.

[0039] This also makes foaming possible in such a production plant in a simple and advantageous way.

[0040] In one embodiment, the production system is designed as a circulation system. In this system, the conveying device is a linear system with a conveyor track. Several production molds are placed simultaneously on this conveyor track, and the mold carriers of these molds are arranged relative to each other along this horizontal longitudinal axis and can be conveyed continuously. Such a circulation system is not a drum system. Therefore, in a circulation system, a production mold does not rotate as a whole around a drum axis, as such a drum is not present. Rather, the production molds are moved along the production path—where the front and back of the door are also attached to the mold and the mold is closed—only in this linear direction along the circulation path of the system.

[0041] In one embodiment, the mold carriers of the production mold are arranged linearly side by side when the mold is open, allowing them to be loaded simultaneously with one side facing outwards and the other with the back side facing inwards. This also enables a high degree of automation in the production system. For example, the loading process can be performed by one or two workers. Similarly, loading can be performed by one worker and a robot simultaneously. It is also possible for both loading processes to be carried out by one robot or two different robots. Thus, the proposed production system offers a high degree of flexibility and adaptability with regard to the deployment of workers and / or robots.

[0042] Such a thing is not possible with the system known from the prior art, as it is described in... Figs. 1 to 3 As explained, this is not possible.

[0043] Another aspect of the invention relates to a method for manufacturing a door for a household refrigerator. According to the invention, the manufacturing process is carried out using a production plant as described above or as an advantageous embodiment thereof.

[0044] The following steps are carried out in the procedure: Providing an open manufacturing mold on a conveyor system of the production plant, such that the mold carriers are arranged in a row relative to each other in the direction of their longitudinal axes; loading the first mold carrier with the front of the door; loading the second mold carrier with the back of the door, whereby the position of the mold carriers relative to each other remains unchanged during this loading with the front and back; filling the inserted front and / or the inserted back with insulating foam; and closing the manufacturing mold by pivoting one mold carrier onto the other mold carrier about the pivot axis of the hinge device.

[0045] In particular, the relative positions of the mold carriers remain unchanged throughout the entire assembly process (loading with the front and back sides). The front and back sides are inserted into the mold carriers accordingly. Once this is done, thermal insulation material, especially in the form of insulating foam, is introduced into at least one of the two mold carriers. The mold is then closed, and the two mold carriers are pivoted onto each other. The mold remains closed until the insulating foam has finished curing.

[0046] Advantageous embodiments of the aforementioned production plant are to be regarded as advantageous embodiments of the process. The components of the production plant, either alone or at least partially in combination, enable the process steps for the process.

[0047] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth", "latitude", "height", etc. indicate the positions and orientations given when the system is used and arranged as intended.

[0048] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Fig. 1 a side view of a manufacturing form as known from the prior art and used in a drum system; Fig. 2 a representation according to Fig. 1 in one to Fig. 2 different stages of manufacture; Fig. 3 the representation according to Fig. 1 and Fig. 2, in which the manufacturing form known from the prior art was pivoted with a mold carrier to allow access to an overhead mold carrier of the manufacturing form for a worker to work overhead; Fig. 4 the schematic representation of an embodiment of a manufacturing plant according to the invention; Fig. 5 the perspective view of a partial area of ​​the manufacturing plant according to Fig. 4 with a manufacturing mold that is arranged in a loading position along the production path of the manufacturing plant and is open; Fig. 6 a side view of the illustration according to Fig. 5 ; and Fig. 7, a further perspective view of a section of the production plant according to Fig. 4 with an open manufacturing mold.

[0049] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0050] In the Fig. 4Figure 1 shows an embodiment of a production plant 1. The production plant 1 is designed and configured for manufacturing a door for a household refrigerator. Furthermore, the production plant 1 is also designed for foaming a door of a household refrigerator. The production plant 1 is designed as a recirculating system. This means, in particular, that it has a conveyor track or a circular path 9 along which the production line is formed. Along this circular path 9, which is a linear path, several separate production forms 2 are arranged in the embodiment. They are moved linearly along this circular path 9 and thus transported or conveyed to the corresponding production stations or production sections.

[0051] Production plant 1 has a loading area 10 along this circulation path 9. Loading area 10 is thus a production area of ​​production plant 1 in which the production mold 2 is open and a front and a back of the door to be manufactured can be inserted or placed into mold carriers 3 and 4 of the production mold 2.

[0052] Manufacturing form 2 also features a hinge device 5. The two separate mold carriers 3 and 4 of this manufacturing form 2 are articulated to each other by the hinge device 5. In one embodiment, this loading area 10 is secured by at least one light barrier of the manufacturing system 1. This prevents access by, for example, a worker 6, as is also the case in the Figs. 1 to 3is shown, and / or monitored by a robot not shown. In particular, a zone that extends in the depth direction (z-direction) when viewing Fig. 4 The area in front of the production mold 2 is monitored. This is particularly advantageous to ensure sufficient clearance when closing the production mold 2 and thus when folding the mold carriers 3 and 4 together via the hinge device 5. For example, a traffic light station can also be implemented in this context, which visually indicates to the operator 6 and / or the robot whether the loading area 10 is accessible again.

[0053] As already mentioned in Fig. 4As can be seen, the manufacturing mold 2, in its open state during the manufacturing process, is designed such that the mold carriers 3 and 4 are arranged in a horizontal row. This means that along a horizontal longitudinal axis A of the manufacturing mold 2, these two mold carriers 3 and 4 are positioned in this horizontal row relative to each other when the manufacturing mold 2 is open. Looking in the direction of this longitudinal axis A, which is located in the horizontal direction or width direction (x-direction) of the production system 1 in this loading area 10, the hinge device 5 is arranged or formed between these two mold carriers 3 and 4. The hinge device 5 is part of the manufacturing mold 2 and is directly connected to the mold carriers 3 and 4.In this context, a pivot axis B of this joint device 5 is formed, which, in this open state of the manufacturing form 2, is oriented perpendicular to this longitudinal axis A in the assembly area 10 of the production system 1. In one embodiment, this pivot axis B is oriented in a plane defined by the depth direction (z-direction) and the height direction (y-direction) of the production system 1. Furthermore, it is oriented at an angle, particularly between 20° and 70°, to the horizontal plane defined by the z-direction and the x-direction.

[0054] These arrangements and orientations apply in particular to the position of the production mold 2, at least within the loading area 10 of the production plant 1. This procedure and orientation make the loading of the mold carriers 3 and 4 with the front 7' and back 8' of the door, as intended in this loading area 10, particularly simple and advantageous. Unrestricted access to both mold carriers 3 and 4 is ensured and simultaneous loading is possible. Overhead work by a worker 6 or overhead loading with a robot is no longer necessary. The front 7' can be an outer wall made of sheet metal. The back 8' can be an inner wall made of plastic.

[0055] Furthermore, in Fig. 4It can also be seen that the production plant 1 has a conveyor system 11. The circulation path 9 is also defined by this conveyor system. The several separate production molds 2 are arranged on this conveyor system 11. The conveyor system 11 has a support table 12 on which the production molds 2 are directly arranged. In particular, this support table has an orientation, at least in the loading area 10, that is inclined at an angle between 20° and 70°, in particular between 30° and 60°, relative to the horizontal plane. This inclination is such that the production mold 2, with its open mold carriers 3 and 4, faces the loading area 10.

[0056] In Fig. 5A perspective view shows a partial section of production plant 1. Specifically, a section of the loading area 10 is shown. It can be seen that the production mold 2 is depicted in its open state. The inclination of the production mold 2 to the horizontal plane is also evident. Along the circulation path 9, particularly in the area of ​​loading area 10, the longitudinal axis A is oriented in the direction of, and thus parallel to, the direction of circulation. Therefore, the mold carriers 3 and 4 of the open production mold 2 are also arranged in a row along this direction of circulation in this zone of the coupling area 10.

[0057] In this state, the mold carriers 3 and 4 are arranged linearly side by side or in a row such that they can be loaded simultaneously with the front 7' of the door and the back 8'. This also means that work can be carried out on both mold carriers 3 and 4 simultaneously and side by side. The loading of the mold carriers 3 and 4 can therefore be performed simultaneously by two different workers 6 and / or by one worker 6 and a robot on the other, or by two separate robots. It is thus possible that no worker 6 is present and, for example, only one robot is used to load both mold carriers 3 and 4.

[0058] As in Fig. 4 and Fig. 5 As already indicated, production form 2 is moved along the circulation path 9 of production plant 1 into the loading area 10. Production form 2 is provided in the open state of the conveyor device 11.

[0059] This is done in the same way as before. Fig. 4 and Fig. 5 This was explained. The first mold carrier 3 is then loaded with the front 7' of the door, and the second mold carrier 4 is loaded with the back 8' of the door. Throughout this entire loading process, the position of mold carriers 3 and 4, particularly relative to each other, remains unchanged.

[0060] Once this assembly is complete and insulating foam has been introduced into the front 7' and / or the back 8', particularly using a foaming unit 17, the next step involves closing this manufacturing form 2. For this, the form carriers 3 and 4 are moved about the pivot axis B, so that the form carrier 3 and the form carrier 4 are pivoted towards each other and then lie against each other in the closed state. Such a pivoting action can be carried out according to the illustration in Fig. 4This closing process can also occur outside the loading area 10, for example, in a closing area 13. In particular, this closing process is carried out automatically by appropriate devices of the production system 1. For example, arms 14 and a guide roller 15 or deflection roller may be provided. When the production mold 2 moves along the circulation track 9 and from the loading area 10 into the closing area 13, the arms 14 automatically make contact. The closing process is then completed automatically by moving around the guide roller 15.

[0061] However, other locking devices are also possible. These can be implemented, for example, with lifting devices such as appropriate lifting cylinders or similar components. These examples of the locking process are not exhaustive. Other devices may also be used.

[0062] As in Fig. 5As can be seen, the two mold carriers 3 and 4 are rectangular in their surface design. In this context, short sides 3a and 3b are oriented perpendicular to the longitudinal axis A. The same applies to short sides 4a and 4b of mold carrier 4. The short sides 3b and 4b, facing each other, are directly connected to the hinge device 5. For this purpose, an upper hinge 5a and a lower hinge 5b are provided in the direction of the pivot axis. These are located at the corners of these short sides 4b and 3b. Long sides 3c and 3d are oriented parallel to the longitudinal axis A. The same applies to the long sides 4c and 4d of the second mold carrier 4.

[0063] Furthermore, in Fig. 5It can also be seen that in this open state of the manufacturing mold 2, particularly when it is located in the loading area 10 of the production plant 1, the mold carriers 3 and 4 are arranged in a common plane. Furthermore, the long side lengths 3c and 4c are essentially aligned with each other. This applies accordingly to the long side lengths 3d and 4d. In this open state of the manufacturing mold 2, the mold carriers 3 and 4 are arranged as shown in the illustration. Fig. 5 even without offset in the vertical direction and / or without offset in the vertical direction.

[0064] It can be provided that the mold carriers 3 and / or 4 have dimensions or widths between 750 mm and 1050 mm, in particular between 800 mm and 1000 mm, with respect to their short side lengths 3a, 3b, 4a and 4b. In one embodiment, at least one mold carrier 3 and / or 4 has a dimension of between 1200 mm and 2500 mm for its long side length 3c and / or 4c and / or 3b and / or 4b parallel to the longitudinal axis A.

[0065] As in Fig. 5 It can also be seen that the long side lengths 3c, 3d, 4c, 4d are oriented parallel to the longitudinal axis A, and in particular also parallel to the orbit 9, when the manufacturing mold 2 is open and when it is in this assembly area 10 of the manufacturing plant 1.

[0066] As already mentioned Fig. 4 As explained, after the insulating foam has been loaded and inserted, the closing is carried out by pivoting the form carriers 3 and 4 around the joint device 5.

[0067] This design is thus realized with a swiveling device 16 of the production plant 1 in the swiveling range.

[0068] Following the insertion of the front 7' and back 8' into the mold carriers 3 and 4 of the manufacturing mold 2, the resulting cavity between the front 7' and back 8' of the door in the manufacturing mold 2 is filled with a thermal insulation material, in particular an insulating foam. For this purpose, the manufacturing system 1 includes, in particular, a foaming unit 17, which is only indicated by a reference numeral and has already been mentioned above. While the manufacturing mold 2 is still open, this insulating foam is introduced, in particular by injection. The mold is then immediately closed. The closed state remains in place until the insulating foam has hardened.

[0069] In one embodiment, the production plant 1 includes a conveying unit 18. The conveying unit 18 is part of the conveying device 11. In one embodiment, the conveying unit 18 may include a rack 19 and / or a rack 20. Furthermore, the conveying unit 18 includes a Fig. 6 unrecognizable, however in Fig. 7 The toothed element 21 shown engages with the rack 19. The toothed element 21 is driven by a motor 22 of the production system 1, and the production form 2 is moved quickly and with high position accuracy on the support table 12.

[0070] Furthermore, it may be provided that the conveying unit 18 includes a roller device 23, as is also the case in Fig. 6 and Fig. 7The roller assembly 23 supports the manufacturing process of form 2 along the production line and thus also along the circulation line 9. Particularly in areas where the manufacturing process of form 2 is not carried out via the toothing device with the rack 19 and / or 20 and a toothed element 21, the movement is realized primarily by the roller assembly 23.

[0071] In Fig. 6 As already explained above, the side view of the design in Fig. 5 The inclined position of the opened manufacturing mold 2 in this assembly area 10 is shown. In particular, the support table 12 can be pivoted into this position by a corresponding swiveling device of the manufacturing system 1.
