PROCEDURE AND DEVICE FOR ZUFUHRUNG THE BAG-WELL-BEHAVED KEEPING NIT FOR A FULLEINRICHTUNG

Invention refers itself on procedures for supplying Faltbeuteln, which are provided from flexible foil material manufactured and with grounds, to Füllstation Beutelfüllund closing machine, with which the bags are taken out of a pile magazine, into which it with their anfeinanderliegen flatrarely, and then during support of its ground upright standing, with the open bag end upward pointing, a Füllstatlon supplied and opened, furthermore on one procedure execution serving device. In the beverage industry more and more one-way packages succeeded. In particular Faltbeutel enjoy of large popularity and are used as consumer-friendly one-way small packings for milk, fruit juices and many other beverages increasingly. FaltbeuteI of this kind are descriptive in the German patent specification Nr.1281140 and the German Gebrauchsmusterschrfft 1786749. One of the problems arising with such Faltbeuteln exists forming materials in view of the small Eigensteiflgkeit the bags in the small Standfestlgkeit of the bags, which lack was tried to remedy by the most different bag organizations. Despite these efforts the supply of such bags proves to the Füllstation of the BeutelfüUund schlleßmaschine to a Fülteinrichtung, for example, as extremely difficult. Here the invention sets with the goal of indicating a practicable procedure of the bag supply for a filling mechanism of developing as well as one procedure execution serving device whereby to proceed and device the requirements must meet a mass production filling. The state of the art knows of course procedures and devices of the registration-in accordance with-eaten kind for supplying from Faltbeutela to the Füllstation of Fü!! - and closing machines as well as to open the bags before reaching the Füllstation, but these before-well-known functions and devices meet the requirements of an industrial Großserienabfül! ung only insufficiently. Like that Entnahmeund opening device at automatic filling machines for Faltund Kreuzbodenbeutel is descriptive in the German laying out writing 1035557, by means of which by a suction mechanism the bags are taken from a pile magazine and handed over then to against each other movable Sauger, which Sauger at the open bag end at both bag flat sides attacks and apart-spreads the latters in such a way that a blowing nozzle to the open bag end be introduced and the bag can be brought by means of compressed air completely in the Offnungszustand. Another device of this kind is descriptive in the German patent specification Nr.68453, with which the withdrawal of folded up bags from a pile magazine takes place by means of a Saugers in connection with pliers attacking within the range of the bag grounds, which pliers the bags in a Au£nahmeta conveyor chain or a similar means pulls in. As soon as the bags within the range of the photograph bags achieved their correct situation, each other facing bag broadsides in the proximity of the upper, open bag end of sow gladly are seized, which the bags hold then in hanging situation. Afterwards, in a following work station, directly at the broadsides within the range of the open bag ends singing means attack, which the bag broadsides mentioned apart-spread and which transfer bags into the opening situation. These before-well-known devices and the functions realisable thereby are complicated and usable for Faltbeutel with only small Eigensteifigkelt only conditionally. In particular it can come with Faltbeuteln of that kind, as they are to be made accessible for procedure execution serving device of the mass production filling by the procedure according to invention and, easily to that no safe opening before reaching the Füllstation Füllund Schlleßmaschine and thus no safe mode of operation is ensured. Those accordingly exists the invention underlying task in the creation of a procedure and a device of the aforementioned kind, with which in simple way supplying from Faltbeuteln to a Füllstation as well as their safe open without the employment more particularly, to the BeuteIoffenseite of attacking Hatternittel succeed. On the basis of initially indicated the procedure this task is solved in process engineering regard thereby that the Faltbeutel will provide running longitudinal folding edge after the withdrawal from the pile magazine for instance in the center of their width extending with one essentially parallel to their Seitenkanten, on which with supplying the bags perpendicularly to the Füllstation the Seitenkanten within the range of the open bag end, from each other removed, are squeezed together about to the bag flat sides and opened through on opposite sides at both flat sides attacking suction means. By bringing a longitudinal folding edge into the Faltbeutel, which runs essentially parallel to the bag side edges, the actually flexible bags receive a sufficient rigidity to the conditions of the Zuf'ührens and with supplying the bags to the Füllstation the Seitenkanten within the range of the open bag end, from each other removed, in the way are squeezed together that home following attack of the suction means at the bag flat sides the latters without substantial resistance can be to-each other-spread. Detailed attempts showed that this principle of the bag supply and opening ensures a safe mode of operation. In appropriate arrangement the procedure can be characterized also thereby that squeezing the bag ELT edges together takes place with supplying to the FülIstation gradually progressively, whereby likewise gradually progressively the Öffrtungsvorgang carries out itself. In device-technical regard the invention goes out from a device with a pile magazine taking up the bags in the folded up condition in a pile, which is provided to a Füllstation with a mechanism for the withdrawal of the bags from the pile magazine as well as with a conveyer system for supplying the bags, which conveyer system covers a circulating conveyance with photograph bags fiir the bags, and with the Sauger are intended to open the not locked bag ends. The task placed to that extent is solved during a such device thereby that the mechanism for the withdrawal of the bags from the pile magazine a folding mechanism is downstream for stamping a longitudinal folding edge into the bags, from which the Faltbeutel supplied intermittently in the machine clock is seized and with grounds pointing downward downward into the photograph bags likewise of the conveyance moved in the machine clock gradually forward of l0 in-promoted and upright standing in these bags taken up, and that for squeezing the bag narrow sides together at the obenliegenden, open bag ends guide bars are intended, before and in the Füllstation reciprocally the conveyer system and above the same extends and their distance from each other in the direction of the Füllstation of a measure, that more largely than the width of the bags is reduced, to a in contrast to this reduced, pre-determined measure. An appropriate arrangement of the device according to invention is characterized that the folding mechanism covers one for instance in the center of the width extending of the Faltbeutel at latter attacking role, under which the bags coming from the pile magazine in longitudinal direction passed through and by a folding edge in form of an easily imprinted longitudinal groove will provide. Another arrangement which it! 'mdung of against-intimately rotating, likewise in the center of the width extending of the Faltbeutel at latter attacking profile roles, consists which are provided with a shaping for stamping a longitudinal folding edge into the bags. In the following Füllund Schläeßmaschine the erfindnngsgemäße procedure is to be further described and to procedure execution serving device in connection with a remark example of a device illustrated schematically in the attached designs to supplying from Faltbeuteln to the Füllstation. Show: Fig.1 the withdrawal from beverage bags latters with lying on top of one another flatrarely taking up pile magazine, the bag delivery to a promoter provided with photograph bags as well as the means for expanding the open bag sides into a Füllstation and a Fig.2 a plan view on the promoter with itself, provided with photograph bags for the beverage bags, to the Füllstation narrowing, expanding the open bag ends of supporting guide bars. The pile magazine --10--, the folded up Getränkebentel lying on top of one another with their flat sides --11-- takes up, become at the open magazine lower surface --12-- the beverage bags in actually well-known way by means of a Saugers --13-- inferred, that at the end one around a fulcrum --14-- tiltable lever arm --15-- is arranged. The folded up beverage bags --11-- are in the pile magazine --10-- in correct position so arranged that the open side points upward with the withdrawal from the magazine. The lever arm --15-- is suggested between the withdrawal position and one shown in Fig.1 striehpunktiert, also --16-- marked transfer point with the remaining device back and forth movably. Under also --16-- suggested transfer position is a folding mechanism --17--, those from two of the Sauger --13-- supplied bag --11-- , vertically downward friction wheels circulating taking up between itself in the sense of a bag promotion --18, 19-- exists. For the guidance of the bag are in the range of the folding mechanism --17-- if necessary further, here however not interesting means intended. With the run by from the Relbrädern --18, 19-- existing folding mechanism --17-- the friction wheel equipped with an appropriate embossing edge coins/shapes --19-- into the beverage bag one lying on top of one another with its Flaehseiten parallel to the bag longitudinal folds running central longitudinal folding, approximately in the kind of a center hanging folding usual for stability improvement with Brief'bögen. Under the folding mechanism --17-- extends a conveyer system --20-- toward to also --21-- designated Füllstation, which can be out-arranged for example as circulating chain conveyors. The direction of rotation interprets arrow --22-- on. The promoter is, like itself from the range the folding mechanism --17-- to over the Fü] lstation --21-- outside extending Trumlage --23-- clarified, with upward open photograph bags --24-- provided. The movement law of the conveyer system is with that the Sauger ù13-- basic rocker movement so co-ordinated that during the supply of a bag --11--of the Sauger over the folding mechanism --17-- to the promoter in each case a photograph bag --24-- directly under the folding mechanism stands, so that the beverage bags after the run by the folding mechanism upright being located into the respective photograph bag of the promoter --20-- arrive. Afterwards scolded the conveyer system around the division measure between two neighbouring photograph bags --24-- appropriate switching step in the direction of the FüUstation --2! -- away. Within the range of the Füllstation --21-- are guide bars reciprocally limiting the supply way of the beverage bags moved transverse to the promotion direction --25, 26-- arranged, at the sections of the bag longitudinal folds in the proximity of the open Behälterselte, exceeding over the bags taking up the photograph bags, feel and their distance from each other in the direction of the Füllstation of a measure, which is larger than the container side, to a in contrast to this reduced, pre-determined measure reduced (see Fig.2). With the supply for garbage station already by means of the guide bars mentioned --25, 26-- within the range of the open bag ends with their longitudinalchewed squeezed together beverage bag become in the FüUstation --21-- from two in relation to lying flat sides of the bags attacking sow gladly --27, 28-- seized and by means of these Sauger apart-spread, so that the introduction of a means to the beverage filling in succeeds by the open container side into the container interior.
