[0001] Welding device and method for operating
[0002] Description
[0003] The present invention relates to a welding device comprising at least one base body with at least one support device and at least one welding element. The welding element can be heated in the installed state and is held on the support device. The support device comprises at least one flow channel, wherein the flow channel has at least one fluid connection and at least one outlet opening in the direction of the welding element. The present invention also relates to a method for operating such a welding device and a method for manufacturing it.
[0004] Welding devices or welding stations are available in many different designs and in many different areas.
[0005] For example, in the production of bags made of film, welding stations can be used, among other things, to create a longitudinal seam to form a tubular film from a partially overlapping film layer and / or to create bottom or top seams. The joining of bag components can also be achieved using a welding station.
[0006] Typically, a so-called welding band is subjected to electricity, which causes it to heat up to a relatively high level. This causes the film to melt locally, for example, sealing it to another layer of film. After the welding process, the resulting weld seam must cool for a certain period of time to ensure stability and allow the welding band to be easily removed from the film.
[0007] This waiting time can significantly reduce the performance of the welding station and thus of the entire system into which the welding station is integrated, as relatively long waiting times are sometimes necessary.
[0008] DE 10 2007 057 177 A1 discloses an elongated welding device, wherein a cooling device made of a thermally insulating material is provided between a heating element and a welding bar. A cooling medium is supplied to a cooling channel in the cooling device in order to accelerate the cooling of the heating element. In order to wet the heating element with the cooling medium over as large an area as possible, the heating element is provided in a curved manner and rests only on the edges of the cooling device. A disadvantage here, however, is that the disclosed design creates a temperature gradient along the heating element, resulting in uneven cooling. Thus, the cooling time must sometimes be significantly extended to ensure sufficient cooling everywhere. Furthermore, the heating element is not supported by the cooling device, as it only rests on the edges.This makes this design quite unstable and the cooling medium can easily escape uncontrollably from the sides.
[0009] Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine Schweißvorrichtung zur Verfügung zu stellen, mit welcher ein schneller Schweißvorgang mit einer stabilen Schweißnaht zuverlässig erreicht werden kann.
[0010] This object is achieved by a welding device having the features of claim 1, by a method for operating the device having the features of claim 19, and by a method for manufacturing the device having the features of claim 24. Preferred developments of the invention are the subject of the subclaims. Further advantages and features of the present invention will become apparent from the general description and the description of the exemplary embodiment.
[0011] The welding device according to the invention comprises at least one base body with at least one support device and furthermore at least one welding element. In the installed state, the welding element is heated or heatable and is held at least in sections on the support device. The support device comprises at least one flow channel with at least one fluid connection. Furthermore, the flow channel has at least one outlet opening and in particular at least two outlet openings in the direction of the welding element. In addition, at least one insulation device is provided between the welding element and the support device, which insulation device is made at least in sections and in particular completely from a thermally insulating material which is in particular also thermally resistant and preferably also has an electrically insulating effect.The insulation device comprises at least two fluid passages, each with at least one opening directed in the direction of the welding element, wherein the fluid passage of the insulation device is in operative connection with the outlet opening of the flow channel.
[0012] The welding device according to the invention can be used in many technical fields. In particular, such a welding device can be used in the production of bags, especially film bags, and preferably in an FFS (form fill seal) machine.
[0013] The base body of the welding device is, in particular, the component that comprises the support device for the welding element. Such a base body can, in particular, be assigned at least one counterpart, which can, in particular, also be designed without a welding element. Depending on the design, the counterpart can, for example, also comprise a permanently heated preheating plate or the like, and / or alternatively, provide a pure support surface. Depending on the design, two or more base bodies with a support device and welding element can preferably be provided, so that the welding process can be carried out from both sides.
[0014] The insulation device is designed in particular such that the welding element is substantially and preferably completely thermally decoupled from the carrier device by means of the insulation device.
[0015] A welding element is in particular at least one welding band, an impulse welding jaw and / or another element which is suitable for producing a weld or a weld seam.
[0016] Depending on the design, connections for the welding element are provided in the support device or through the support device so that the welding element can be operated thermally, electrically and / or in other suitable ways.
[0017] The fluid connection of the flow channel can in particular be supplied with at least one fluid, wherein a controllable supply is particularly preferred.
[0018] The outlet opening of the flow channel in the support device can, for example, be a bore or the like, which guides the fluid selectively toward the insulation device or the welding element. Depending on the design, the opening can also be designed, for example, as a groove or slot, so that the flow channel is open at least in sections toward the insulation device and is covered by the insulation device or closed except for the openings in the insulation device.
[0019] The welding device according to the invention offers many advantages. A significant advantage is that the welding element is thermally decoupled from the support device by the insulation device. Furthermore, the special design of the insulation device and the support device allows the heated welding element to be cooled relatively quickly by a fluid, such as an air stream, before, after, and / or during a welding process. In particular, a previously created weld seam can also be cooled down, so that it achieves sufficient and, depending on the design, final stability very quickly. This can sometimes significantly reduce the process time.
[0020] By passing a fluid used for cooling through the insulation device, which is thermally resistant and insulating, a particularly rapid cooling of the welding element can be achieved, since the support surface or the holder on the carrier device is not heated up or not heated up significantly by the welding element itself.
[0021] Preferably, the insulation device is made of silicone, at least in sections. In particular, it is provided that the insulation device consists or is made entirely of silicone. Silicone has the preferred properties of an insulation device, as it is both insulating and temperature-resistant.
[0022] Particularly preferably, the insulation device comprises at least one cooling channel, which is operatively connected to the at least one fluid passage. Such a configuration can enable even better cooling of the welding element. Thus, depending on the configuration of the cooling channel, the area of the welding element that is operatively connected to a cool fluid flow can be increased.
[0023] In expedient embodiments, the cooling channel has at least one intersection, which in particular does not pass through the opening of the fluid passage. This allows for advantageous fluid distribution within the insulation device. The branching branches of the cooling channel can branch off transversely or in a different manner from the main channel or the cooling channel, e.g., in a fishbone pattern or in a zigzag pattern.
[0024] In preferred embodiments, the cooling channel is open, at least in sections, at least in the direction of the welding element. Particularly with such a configuration, particularly effective cooling of the welding element can be achieved, since, depending on the design of the cooling channel, particularly large-area cooling of the welding element can be achieved, even if a fluid, e.g., an air stream, is introduced into the insulation device only at one or more points.
[0025] Particularly preferably, a plurality of openings directed toward the welding element are provided, wherein the plurality of openings are provided in particular to correspond to the outlet openings of the support device. Depending on the design, a fluid passage with several openings or separate fluid passages, each with one opening, can be expediently provided.
[0026] Preferably, the number of openings in the insulation device corresponds to the number of outlet openings in the support device. Thus, a fluid flow or a fluid can be guided through each outlet opening in the support device toward the welding element, preferably through the opening in the insulation device, in order to achieve rapid cooling of the welding element.
[0027] Preferably, at least two openings of the insulation device are connected to one another via at least one common cooling channel. This also allows particularly advantageous cooling to be achieved.
[0028] In expedient developments, the cooling channel has at least one outlet opening, which is arranged or provided, in particular, substantially transversely to the opening in the insulation device. Such a configuration makes it possible, in particular, to discharge fluid or air from the cooling channel, especially even when a welding element otherwise covers the cooling channel.
[0029] Preferably, the insulation device is designed in a frame-like manner. In such a configuration, a circumferential flow channel is advantageously also provided in the support device, and in particular, the welding element is also provided in a ring-shaped or frame-like manner and is arranged on the support device or on the insulation device.
[0030] Depending on the design, the insulation device can also be bar-shaped or elongated. In this case, the desired configuration of the weld seam is generally the decisive factor for the shape and design of the welding element and / or the insulation device.
[0031] In general, the welding element or the support device or the insulation device or the components assigned to these components can also be shaped in such a way that three-dimensional features can be created or the weld seam follows a three-dimensional contour.
[0032] In advantageous further developments, at least one processing device is provided which is suitable and designed to be received at least in sections in the carrier device and to reach at least temporarily and at least in sections through the plane of the welding element. Such a configuration makes it possible to provide further processing steps simultaneously with and / or at a time-delayed time to a welding operation and / or to arrange auxiliary means in the welding device or in the base body and / or the counterpart. For example, a knife and / or a gripper device, for example a vacuum gripper, can be provided.
[0033] Preferably, at least one covering device is provided, which in particular covers the welding element. Depending on the configuration, the covering element also covers the insulation device and / or the support device or the base body, at least in sections. In this case, a covering device is in particular designed to be heat-conductive and / or is provided with the welding element.
[0034] In advantageous embodiments, the covering device comprises at least one recess for the passage of the processing device. With such a configuration, the welding element is suitably and securely covered, while still allowing the use of any processing device provided.
[0035] Preferably, at least one quick-change device is provided, in particular with an angle compensation device. Using such a quick-change device, the welding device or welding element can be mounted and aligned quickly.
[0036] Preferably, the flow channel in the support device is designed to cool the support device at least in sections. This makes it possible, in particular, to cool the heat that transfers to the support device despite the insulation device simultaneously with the cooling of the welding element.
[0037] In particular, it is provided that the flow channel comprises at least one exhaust air duct, which can in particular comprise at least one silencer or the like. An exhaust air duct can be used, for example, to ensure that an excess of a fluid used for cooling can be supplied to the insulation device. The excess fluid then escapes via the exhaust air duct. Depending on the design, the exhaust air volume can be regulated by means of the silencer, and unwanted noise when the fluid escapes can be reduced or even avoided.
[0038] In expedient developments, the insulation device is suitable and designed to direct the fluid flow laterally toward the welding element. With such a configuration, particularly suitable cooling of the welding element can be achieved. This can be achieved, in particular, by appropriate shaping and / or appropriately provided cooling channels and / or openings.
[0039] Preferably, the insulation device is suitable and designed to cool at least one electrical connection of the welding element. In particular, openings and / or cooling channels can be provided in the insulation device such that a fluid conducted through the insulation device also cools the electrical connections of the welding element.
[0040] Particularly preferably, the insulation device is suitable and designed to direct a fluid flow, at least in sections, directly onto the welding element. For this purpose, the welding element is provided, in particular, directly downstream of the opening in the insulation device in the flow direction. Thus, a fluid directed through the opening is guided directly onto the welding element.
[0041] Preferably, no barriers or the like are provided between the opening in the insulation device and the welding element.
[0042] The method according to the invention is suitable for operating a welding device as described above. The welding element is heated to produce a weld seam, wherein, at least after the welding process, at least one fluid is supplied to the fluid passage of the insulation device via the outlet opening in the support device and is directed to the welding element via the opening of the fluid passage in the insulation device in order to cool the welding element at least in sections.
[0043] In particular, cooling of the welding element at least in sections and at least temporarily also causes cooling of the previously produced weld seam.
[0044] The method according to the invention also offers the advantages already explained above. In particular, a significantly faster cooling of the welding element can be achieved, which in particular also simultaneously cools and thus preferably stabilizes the weld seam. The supplied fluid is preferably temperature-controlled. In particular, a cooled or pre-cooled or cold fluid such as cooled air and / or a cooled or cold gas and / or a cooled gas mixture can be supplied as the fluid in order to bring about an even faster cooling of the welding element.
[0045] Particularly preferably, at least one cooling channel is provided in the insulation device, and the insulation device is cooled by at least one fluid conducted through the cooling channel. In particular, simultaneous cooling of the insulation device and the cooling of the welding element can be provided. Depending on the design, however, certain structural features can also be provided, for example, separate cooling channels, in order to cool only the insulation device, at least in sections.
[0046] Particularly preferably, at least one cooling channel is provided in the insulation device, and the welding element is cooled at least in sections by at least one fluid conducted through the cooling channel. By providing at least one cooling channel, through which the fluid introduced into the insulation device via the opening is further distributed, a welding element can be cooled particularly effectively and, in particular, over a larger area.
[0047] In expedient embodiments, at least one processing device reaches through the plane of the welding element at least in sections before, after and / or during the welding process. Such an embodiment can be provided in particular when a frame-like welding device or a frame-like welding element with correspondingly frame-like additional components is provided. A further method according to the invention is suitable for producing at least one insulation device for at least one welding device, as described above. In this case, at least one at least two-part casting mold is provided, wherein liquefied insulating material, for example liquid silicone, is poured into the casting mold.
[0048] Preferably, the material is then removed after curing.
[0049] The method according to the invention for producing an insulation device enables particularly simple production of insulation devices.
[0050] In this way, the sometimes preferred complex structures with a large number of openings and / or branched cooling channels can be produced quickly and cleanly through the casting process.
[0051] In particular, the mold is manufactured at least partially using at least one 3D printing process. This enables particularly cost-effective, simple, and flexible mold production.
[0052] Further advantages and features of the present invention will become apparent from the embodiment which will be explained below with reference to the accompanying figures.

[0066] Fig. 15 is a detailed view of an insulation device for a welding device according to Figure 13.
[0067] Figure 1 shows a purely schematic exploded view of an embodiment of a welding device 1 according to the invention.
[0068] In the exemplary embodiment shown here, the welding device 1 according to the invention comprises a base body 2, which provides a support device 3. In the exemplary embodiment shown, the support device 3 has a receptacle 9 for an insulation device 50.
[0069] When installed, the insulation device 50 is arranged between the support device 3 and a welding element 4, which is designed here as a welding band. The welding element 4 can be heated via electrical connections 15. Furthermore, in the embodiment shown here, a covering device 10 is provided, which is provided here as a closure of the base body 2 and which covers the welding element 4.
[0070] In the illustrated embodiment, the welding element 4 is provided in a frame-like manner, allowing a circumferential weld seam to be created. Therefore, the design of the insulation device 50 and the support device 3 or the base body 2 is also provided accordingly.
[0071] The insulation device 50 is made of a thermally resistant and insulating material 51 so that it is not damaged by the welding element during welding and also does not absorb or significantly absorb and / or conduct the heat generated during welding. In the example shown, the insulation device 50 is made entirely of silicone 54.
[0072] Figure 2 shows the base body 3 and the insulation device 50 again in an enlarged view. It can be seen here that a flow channel 5 is provided in the support device 3 or the base body 2, into which a fluid such as air, a gas, or, depending on the design, a liquid and / or the like can be introduced via a fluid connection 6.
[0073] In the direction of the welding element 4 or the insulation device 50, a plurality of outlet openings 7 are provided in the embodiment shown here in connection with the flow channel 5, which here correspond to openings 53 of a fluid feedthrough 52 of the insulation device 50. The fluid guided into the flow channel 5 via the fluid connection 6 is guided via the outlet opening 7 through the fluid feedthrough 52 or the openings 53 in the direction of the welding element 4. In the embodiment shown here, the openings 53 are connected to one another via a cooling channel 55, so that a particularly large-area cooling of the welding element 4 can be achieved via the fluid flowing through the openings 53 or the cooling channel 5.
[0074] Figure 3 shows a purely schematic representation of a casting mold 100 which can be used to produce an insulation device 50 for a welding device 1 according to the invention.
[0075] In the embodiment shown, the casting mold 100 is provided in several parts and comprises an upper part 101 and a lower part 102, wherein an intermediate part 103 is also provided for shaping.
[0076] To produce an insulation device 50 from a thermally insulating material 51, the casting mold 1 is assembled and liquefied material 51 is filled into the mold 100 via the filling openings 104.
[0077] After curing, the casting mold 100 can be disassembled, and the insulation device 50 can be removed. In the illustrated embodiment, the casting mold 100 is manufactured using a 3D printing process, which enables, in particular, the flexible production of complex insulation devices 50, even those with a three-dimensional design or shape.
[0078] Figure 4 shows a purely schematic illustration of an insulation device 50 for a welding device 1 according to the invention, which can be used, for example, in the exemplary embodiment shown in Figures 1 and 2. In the exemplary embodiment shown here, the frame-like insulation device 50 is made entirely of a thermally insulating material 51, with silicone 54 being used here. Silicone 54 also offers the advantage that the material is not only thermally insulating but also thermally resistant.
[0079] In the illustrated embodiment, it can be seen that the fluid passage 52 of the insulation device 50 comprises a plurality of openings 53 through which fluid supplied via the outlet openings 7 flows out. In the illustrated embodiment, the openings 55 are connected to one another via a cooling channel, so that the fluid used for cooling can flow through the openings 55 and also further through the channel 55, thus effecting even better cooling of the welding element 4.
[0080] In the embodiment shown here, intersections 56 are provided in the cooling channel 55, which in this case are located at a different location than the openings 55 or not in the region of the openings 55. Outlet openings 57 can be provided via the intersections 56, which here provide transverse extensions of the cooling channel 52, so that the air flowing through the cooling channel 55 can also exit when the cooling channel 55 is covered at the top by the welding element 4.
[0081] In the illustrated embodiment, it is also shown that the cooling channel 55 also extends into the corner regions of the frame device, into which the electrical connections 15 of the welding element 4 run, so that these too can be cooled by means of the insulation device 50 or by means of the air or fluid flowing through the cooling channels 55. Figure 5 shows a purely schematic plan view of an embodiment of a welding device 1 according to the invention. Here, too, the frame-like design of the insulation device 50 can be seen, which here consists of a thermally insulating material 51, with silicone being used as the material here too.
[0082] Here, too, the intersections 56 in the cooling channel 55 can be seen, via which a good distribution of the fluid used to cool the welding element 4 is enabled.
[0083] Furthermore, in the lower left and upper right corners, it can be seen that a special shape of the insulation device 50 is provided to enable cooling of the tab-like electrical connections 15. The insulation device 50 is also designed to be electrically insulating.
[0084] Figure 6 shows a purely schematic cross-section through the area CC in Figure 5. Here, the flow channel 5 in the support device 3 of the base body 2 can be seen. It is shown that outlet openings 7 lead out of the flow channel 5 in the direction of the welding element 4 to be cooled, to which corresponding openings 53 of the fluid feedthrough 52 in the insulation device 50 are assigned.
[0085] If a fluid is fed into the flow channel 5 via the fluid supply 6, it can pass through the outlet openings 7 into the fluid passage 52 or the corresponding openings 53 and thus directly hit the welding element 4 arranged above it and thus cool it.
[0086] Figure 7 shows a further lateral sectional view through a welding device 1 according to the invention, also illustrating the flow channel 5. This shows a cross-section through the cooling channel 55 of the insulation device 50 in the region of an intersection 56. Thus, the open ends of the transverse channel sections and the outlet openings 57 can also be seen here.
[0087] Figure 8 shows a purely schematic perspective view of an embodiment of a welding device 1 according to the invention or of a base body 2 of such a welding device 1.
[0088] In the embodiment shown here, it can be seen that the base body 2 or generally the welding device 1 comprises a quick-change device 12, which here also comprises an angle compensation device 13.
[0089] Figure 9 shows, purely schematically in a sectional view, the fluid guide through the base body 2 or the carrier device 3 of a welding device 1 according to the invention.
[0090] Fluid is fed into the flow channel 5 via a fluid connection 6. In the exemplary embodiment shown here, it is shown that an exhaust air channel 16 can also be provided at one end of the flow channel. This exhaust air channel 16 carries away excess fluid, which in this case is fed in excess to the insulation device 50. Furthermore, a silencer 17 is connected here, via which the amount of exhaust air can be adjusted and which reduces or prevents unwanted noise, for example hissing or whistling. Such a silencer 17 can preferably also provide the function of a pressure relief valve. Figure 10 shows a purely schematic embodiment of a welding device 1 according to the invention, the welding device 1 being shown here in an assembled state.
[0091] Here, the welding device 4 comprises a base body 2 and a counterpart 14. In the illustrated embodiment, both the base body 2 and the counterpart 14 comprise a quick-change device 12 with an angle compensation device 13. Here, the base body 2 and counterpart 14 are provided offset or rotated by 90° relative to one another, so that optimal alignment in all directions and in all planes can be achieved via the angle compensation devices 13 of the base body 2 and counterpart 14.
[0092] In the embodiment shown here, the counterpart 14 does not comprise a welding element 4, but serves only as a support surface or counter surface for welding.
[0093] Figure 11 shows a purely schematic representation of the base body 2 of the welding device 1 according to Figure 10, wherein in the embodiment shown here it is shown by way of example that a processing device 60 can be arranged in the base body 2, wherein the processing device 60 is designed here as a cutting device 61 with a plurality of blades.
[0094] Accordingly, in the illustrated embodiment, the covering device 10 has recesses 11 through which the cutting device 61 can pass when actuated. This allows the cutting device 61 to pass through the plane 8 of the welding element 4 for processing, for example, a film during bag production. Figure 12 shows a purely schematic, partially sectioned perspective view of the welding device 1 according to Figure 10.
[0095] Here you can see the quick-change device 12 with the angle compensation device 13 on the counterpart 14.
[0096] Figure 13 shows an embodiment of a bag manufacturing device 200 which comprises a welding device 1 according to the invention.
[0097] Figure 14 shows a sectional side view of the welding device 1 from Figure 13. In the embodiment shown here, the welding device comprises two base bodies 2, each with a welding element 4, which are moved toward each other to weld film into a bag.
[0098] In Figure 15, it is shown purely schematically and by way of example that a welding element 4 and thus also the corresponding insulation device 50 and the support device (not shown) can be designed in a bar-like or elongated manner.
[0099] Such a design is shown purely schematically and by way of example as a further embodiment in comparison to the previously frame-like design of a welding element 4 or an insulation device 50. List of reference symbols
