DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

(7) FIG. 1 shows a schematic illustration of a packing arrangement 100 according to the invention, [comprising] a bagging unit 110, a pallet loading device 120, and a load securing device 130. The bagging device 110 is supplied with a tubular packing means 111, which is stored on a roll 112. This packing means 111 is pulled off the roll 112. The front end of this packing means 111 is provided with a bottom seam and cut to a bag length such that a bag is formed, which is open towards the top. It is grasped at its upper end by a pair of graspers and transported to a filling station. Here, the upper end is pulled such that the inside of the bag becomes accessible. Now the bag can be filled with the product to be bagged, which is freely flowing, but represents a solid substance (thus is not a liquid) in the desired quantity, for example 25 kg. The product is here stored in a silo 113 and is taken therefrom. Subsequently the still open but already filled bag is moved to a sealing station, in which a head seam is applied, sealing the bag, generally by way of a welding process.

(8) The filled bags 139 are now transported with a transport device 114, which may comprise several conveyor belts, to the pallet loading device 120. Here, several bags 139 are collected above a pallet 121 and arranged there. This arrangement of bags is placed onto the pallet and forms there a bag layer 122. In this bag layer the bags are generally arranged varying in reference to the previous bag layer, in order to this way increase the stability of the stack of bags 123.

(9) The completely loaded pallet 121 is now moved by a conveyor device 124 to the load securing device 130, where the loaded pallet is provided with a cover, a so-called stretch hood 131. For this purpose respectively one gathering finger 133 is arranged at each corner, above the loaded pallet, on which a film hose 132 is stored showing a certain length. Subsequently the gathering fingers 133 move diagonally towards the outside, so that seen in the horizontal direction they are outside the dimensions of the pallet. Here the film hose 132 is stretched. Now the gathering fingers 133 can move downwards and here successively release the film hose so that a smooth hood develops over the loaded pallet. Before or during the downwards motion of the gathering fingers the film hose 132 is severed according to the length required and closed with a welding seam so that the hood 131 is closed at the top. The stretched hood serves not only to securely keep the bags on the pallet during transportation, but it can also serve for protection from environmental influences, such as moisture.

(10) Each of the above-mentioned devices 110, 120, 130 comprise in this exemplary embodiment a control and information device 140, 150, 160, which saves and renders available respective information regarding events in the respective device. For this purpose, the storage device may comprise a computer and at least one bulk memory component, for example in the form of a hard drive, on a magnetic basis and/or a solid-state drive (semiconductor drive). In this storage component information can now be saved regarding various but specified events. Some of these events, for example production of a filled bag or sack occur continuously, while other events may occur irregularly. However, storage regarding the respective information occurs for all events.

(11) The storage device 140, 150, 160 may respectively also comprise a monitor 141, 151, 161, on which illustrations can be displayed comprising the various information saved. Furthermore, an input device 142, 152, 162 may be provided, by which far example commands can be entered leading to the above-mentioned illustrations. Data conductors 143, 153, 163 lead from the various components of the devices to the storage device 140, 150, 160.

(12) FIG. 2 shows a schematic illustration of another packing arrangement 100 according to the invention, with the devices 110, 120, 130 being equivalent to those of FIG. 1 and thus the individual reference characters not being shown for reasons of clarity. Here, a difference from the embodiment in FIG. 1 is given in that the data conductors 143, 153, 163 lead to a common storage device 200, which saves the above-mentioned information centrally for all devices. The actual storage components may alternatively be arranged in the individual devices and here save the information, which increases the operational safety, for example when one of the devices malfunctions. The storage device 200 may in this case primarily serve for information processing and illustration. This means that here the three devices 110, 120, 130 are networked together.

(13) FIG. 3 shows an illustration of the function of a data filter of a packing arrangement according to the invention. Here a database is shown which provides a software connection of events and the corresponding information and organizes the storage in the storage components. Additionally, the database provides information also in case of inquiries.

(14) In a special data inquiry, data can now be obtained in the embodiment shown, with only search criteria and/or search ranges being permitted for the static information. For example the user, the recipe, the time, and the machine can be determined for the data inquiry. For example, all information can be searched for allocated to events which occurred within the most recent 24 hours. A respective data inquiry in the dynamic information is not provided. The data inquiry is shown in FIG. 3 as filter 301. The data inquiry can then be disclosed to the user by a display medium 302, for example a monitor.

(15) FIG. 4 shows an embodiment for an illustration of the results of a data inquiry on a monitor 400. In a display range 401 the filter is shown, i.e. the lettering filter represents the filter name. Under this filter name the filter can be saved with the respective search criteria. Now, all events are displayed in the illustration range 402 or all events are shown that match the static information of the search criteria. The event used is shown in FIG. 4 as view 1, view 2, etc. A view can now be selected, in which all static and/or dynamic information regarding the selected event can be displayed. For this purpose, the illustration field 403 is provided.

(16) The exemplary embodiment of FIG. 3 and FIG. 4 serves for the simple formation of a filter as well as the clear illustration of the search results. This way, an operator can quickly be informed about important matters of the packing arrangement, such as previous maintenance work performed.

(17) The invention being thus described, it will be apparent that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be recognized by one skilled in the art are intended to be included within the scope of the following claims.
