    The invention relates to a filming device for fully automatic filming of goods according to the preamble of claim 1.
    Foliation devices are used to cover or wrap goods with a film. For example, the goods are mainly packed manually or semi-automatically in sawn timber production plants, with staples of plastic or light metal or nails usually being used for positioning or fixing the foil as an aid. Automatic filming devices often use film hoods to foil goods.
    In general, the film is applied to the material to be foiled and provided with a strapping or put over the goods as a prefabricated film hood and then fixed with staples or nails or an additional strapping. The adaptation of the film to the different dimensions of goods is usually carried out by a film exchange on a film dispenser.
    A disadvantage of such Folierungsvorrichtungen is that prefabricated film hoods always require the same dimensions of the goods, which is why film hoods do not allow flexibility in terms of the dimensions of the goods. In order to adapt the film to the respective dimensions of the goods, the film dispenser must be converted over time. Furthermore, automatic filming devices usually require a large amount of space and / or they require a complicated and expensive mechanism and increased processing times. Manual and semi-automatic foiling processes are not only cumbersome and cumbersome, but due to various personnel-demanding steps also correspondingly personnel, cost and time-consuming.
    The object of the invention is therefore to provide a foliation device of the type mentioned, with which the mentioned disadvantages can be avoided, with which a simple, space-saving and fully automatic foiling of goods can be accomplished.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that the foiling process is uncomplicated and / 25
    36909 runs fully automatically. Thus, the operating staff is relieved, since no human steps for the wrapping of the goods are required and can be saved according to employee costs. Furthermore, a simple, reliable and fully continuous operation of the filming device is made possible. Due to the automation, the efficiency of the filming device is also increased. Furthermore, there is the advantage that no fixing elements such as staples, nails or strapping are needed to position the film on the estate and / or to fix, whereby visually appealing results of high quality are possible. Since the available space is often very limited in various systems and production areas, another advantage of the filming device is that the filming device can be shorter in size than the product to be foiled. Due to the space-saving design, the foliation device is thus also suitable for production spaces with limited space. By the welding of both wrapped with foil side edges of the estate by the welding device in the welding plane on the one hand, the processing time and on the other hand, the space required by the filming device kept low because the good for one or more welding steps does not have to be rotated or raised. Since the grippers grip the film only at its opposite corners and pull and hold from the ready position to the welding position, can be on a complex and space-demanding mechanics as used, for example, in articulated robot arms used, and it is further automatically finds a certain tightening of Foil instead, whereby kinks and wrinkles of the same, disposed in the welding position Good avoided. Another advantage of the simple design of the gripper and the welding device is that these components require little maintenance due to their simplicity. Due to the welding of the side edges of the Guts a multi-layered film is avoided on Good, since film projections do not need to be handled. Since the respective material 2 is foiled with a perfect fit, additional positioning or fixing means can be dispensed with.
    Furthermore, the invention relates to a method for operating a
    Foiling apparatus according to claim 10.

    Figures 1a to 10 show at least parts of preferred embodiments of a filming apparatus 1 for automatically wrapping goods 2 comprising a conveyor 3 for conveying a stock 2 through a filming duct 4 of the filming apparatus 1, the filming apparatus 1 for providing film 5 for wrapping of the item 2 has - viewed in the operating position - above the Folierungskanals 4 arranged film providing device 6, wherein the filming device 1 further comprises at least two movably arranged gripper 7 and a welding device 8. In FIGS. 2 to 10, not all features are provided with reference numerals.
    The filming device 1 serves to cover goods 2 with film 5, or to encase, in order to protect the goods 2 from external environmental influences. The word goods 2 denotes any kind of piece goods, but in particular stacks of goods 2 and more preferably
    Lumber pile. The conveying device 3 conveys a product 2 through the filming channel 4 of the filming device 1 in a conveying direction 14. The speed of conveying the product 2 is controllable. The Folierungskanal 4 is the area in which the goods 2 are foiled. The filming channel 4 can also be seen as that volume which is delimited by the conveyor 3 and the film supply device 6. The film 5 may consist of a plastic such as polyethylene or a tear-resistant fabric. In the operating position, the film supply device 6 is arranged above the filming channel 4, which is shown by way of example in FIG. 8. The material 2 is sheathed in particular on five sides with the film 5. More specifically, the material 2 is encased in particular on the two side surfaces, on the two end faces 15, 17 and on the upper side 20 with the film 5. By operating position, it is meant that the foaming device 1 is constructed ready for operation and is not tilted at an angle, as in a transport state at / 25, for example
    36909 a transport could be the case.
    1a-1e show a schematic exemplary representation of individual process steps, wherein a good 2 is moved in the conveying direction 14 through the filming channel 4 and is foiled. In the welding plane 12 in each case one, in particular triangular and double-layered, film projection 16 is welded to the side edges of the respective two end faces 15, 17 of the product 2 by the welding device 8, which is exemplified in the highlighted front views of the respective end face 15, 17 of the product 2 in FIG Fig. 1c and in Fig.1e is shown.
    The filming device 1 comprises at least two grippers 7 arranged in a movable manner. The grippers 7 may have at least one, preferably more than one clamping device or pliers for gripping the film 5. At least one gripper 7 can also have a clamping strip for gripping the film. The
    Film supply device 6 provides the film 5 for wrapping the goods 2 ready. The welding device 8 welds the film 5 to the goods 2. The grippers 7 grip the film 5 at opposite corners in the ready position 9. The ready position 9 can be seen with respect to the grippers 7 as the position in which the grippers 7 of the film supply device 6 are spatially closest to each other and in which the film providing device 6, the film 5 for the gripper 7 ready to take over ready provides, which is exemplified in Fig. 4 and in Fig. 5. FIG. 5 further shows, by way of example, how a gripper 7 grips the film 5 provided by the film supply device 6. The gripper 7 is arranged on a moving device 21.
    The grippers 7 are designed to pull the film 5 from the ready position 9 into a welding position 10. In the welding position 10, the grippers 7 are spatially furthest away from the film supply device 6 in the operating state. In the welding position 10, the grippers 7 are further arranged in the welding plane 12 and substantially at the level of an upper side 11 of the conveyor 3, which is shown by way of example in FIG. The welding plane 12 is that plane in which the film 5 is welded to the material 2, in particular to two side edges 13 of the product 2 sheathed with film 5. The welding plane 12 can be regarded as an imaginary plane, which is arranged parallel to the end face 13 of the product 2, in particular positionally stable. The top 11 of the conveyor 3 is as / 25
    36909 that side of the conveyor 3 defines on which the Good 2 is arranged in the operating state, which is exemplified in Figure 10 can be seen.
    It is provided that the at least two grippers 7 between the
    Provision position 9 and the welding position 10 are predeterminably arranged movable, the grippers 7 are adapted to grab the film provided by the film providing device 6 slide in the ready position 9 at two opposite corners and to move from the supply position 9 in the welding position 10 and hold, wherein the grippers 7 are arranged in the welding position 10 in a welding plane 12 and substantially at the level of the top 11 of the conveyor 3, and that the welding device 8 is formed, both arranged in the welding plane 12 and covered with foil 5 side edges 13 of the estate 2 to weld.
    For parallelepiped material 2, the welding plane 12 is substantially normal to the conveyor 3 and transverse to the conveying direction 14. The grippers 7 are arranged in the welding position 10 in the welding plane 12 and substantially at the level of the top 11 of the conveyor 3, to ensure that the film 5 extends substantially to a lower edge of the Guts 2 during welding.
    Furthermore, a method for operating a foaming apparatus 1 is provided, wherein material 2 to be foiled is conveyed by means of a conveyor 3 through a foliation channel 4 of the foiling apparatus 1, film 5 being provided for foiling the product 2 by a film supply means 6 arranged above the foiling channel 4, wherein at least two movably arranged grippers 7 in a ready position 9 grip the film 5 provided by the film supply device 6 at two opposite corners, the grippers 7 holding the film 5 being moved from the supply position 9 into a welding position 10, the grippers 7 in the welding position 10 are arranged in a welding plane 12 and substantially at the level of an upper side 11 of the conveyor 3, wherein the material to be foiled 2 is moved by means of the conveyor 3 until a first end face 14 of the product 2 in the welding plane 12 a is arranged, wherein arranged by the welding position 10, the film holding gripper 7, the film 5 / 25th
    36909

    Folierungskanals 4 and conveys the Good 2 through the Folierungskanal 4. The conveyor 3 may preferably as a conveyor belt, particularly preferably as a longitudinal conveyor and in particular as a telescopic conveyor, be formed and protrude beyond the length of the Folierungskanals 4. The material 2 is moved by means of the conveyor 3 until the first end face 14 of the product 2 is arranged in the welding plane 12. In the case of a cube-shaped or cuboid-shaped material 2, both side edges 13 of the first end face 14 of the product 2 are correspondingly arranged in the welding plane 12. In particular, both side edges 13 can be welded at the same time by means of the welding device 8 in the welding plane 12.
    This results in the advantage that the entire foiling process is uncomplicated and fully automatic. Thus, the operator is relieved, since no human steps for the foiling of goods 2 are required and can be saved according to employee costs. Furthermore, a simple, reliable and fully continuous operation of the filming device 1 is made possible. Due to the automation, the efficiency of the filming device 1 is also increased. Furthermore, there is the advantage that no fixing elements such as brackets, nails or strapping are needed to position the film 5 on the estate and / or to fix, whereby visually appealing results of high quality are possible. Since the available space is often very limited in various plants and production areas, another advantage of the filming apparatus 1 is that the filming apparatus 1 can be made smaller in size than the product 2 to be sheeted.
