DEVICE FOR CONNECTING THE UMSCHNUERUNGS CENTRAL ENDS AT UMSCHNUERUNGSMASCHINEN

The invention concerns a device for connecting the Umschnürungsmittelenden at Umschnürungsmaschinen, with which the Umschnürungsmittelenden between an upper and lower printing cheek is pressed together and with which of a side of the Umschnürungsstelle the grip arms shiftable to the other page is intended, which a Schneidmesser for splitting the Umschnüs rungsmittels is assigned. There is devices of this kind well-known, with which the grip arm must umfahren, in order to arrive of a side of the UmschnürungssteUe at the other side, the printing cheek. One keeps the disadvantage of large, complex and heavy designs connected to Hiedurch with relatively high manufacturing costs. Furthermore a long way of the grip arm is present when driving the printing cheek around, whereby the device and thus the Umschnürungsmaschine with smaller achievement work. Task of the invention is it, in particular, i.e. additionally to itself the task productions resulting in from description and requirements, one device of simple and compact structure would genericin accordance with-eat in such a manner to indicate that the hit under achievement of a higher Umsehnürungsleistung needs to put back only a small way. Solved this task is according to invention thereby that the lower printing cheek sits to a side of the grip arm and itself with this shifted. According to such arrangement is one would indicated genericin accordance with-eat device, which is characterised essentially on the one hand by a simplified structure and on the other hand by a increased work. Under the common misalignment of printing cheek and grip arm 21) the latter needs to only go through a small way. The necessary time becomes shorter thereby. Furthermore the grip arm steering construction units can be kept simpler and smaller, which leads to the above-mentioned compact design of the device. In practice this looks in such a way that with usual overlap length of the Umschnürungsmittelenden the device according to invention is about half as large as the well-known device of these art. this substantial reduction brings the advantage of a smaller weight and permits it, the manufacturing costs to lower. Then the entire Umschnürungsmaschine can receive a more compact structure below Umschnürungsti. Also the according to invention works according to device the shorter grip arm way in relation to the well-known solutions more störungsunanfäiliger. A favourable characteristic consists in accordance with the invention of that the lower printing cheek is subjected to this lengthwise-relocatable to the Greffer stored, in pressure position above a tappet arranged and. Despite common misalignment of grip arm and printing cheek the latter is relative to the Greffer shiftable. In the pressure position then the printing cheek lies above the tappet, which takes over the actual controlling of the printing cheek. Connecting the Umschnürungsmittelenden is possible e.g. with welding or with a clip. It proves according to invention as favourable that some upper, which trains a Greffer retaining plate course-turned edge of the lower printing cheek the knife edge. Thus the lower printing heel fulfills a dual function. On the one hand it serves for the Zus.m, nenpressen the Umschnürungsmittelenden, and on the other hand it splits the Umschnürungsmittel after finished Umschnürung. The gumption effect thereby obtained according to the misalignment of printing cheek in relation to the grip arm. Then it is of advantage in accordance with the invention that the lower printing cheek is spring-tensioned in opening direction. It is given guarantee thereby that to finished connecting procedure of the Umschnürungsmittelenden for example by welding the printing cheek always returns to its regulation-fair initial position. Controlly technical it is favourable according to invention that the tappet sits at the free end of a cam controlled balance beam. With each common misalignment of grip arm and printing cheek this withdraws from the path and permits a troublefree misalignment of the printing cheek and the grip arm. It goes only with the closing procedure into action. Finally it still according to invention is of advantage that a spring-tensioned free course between Stöße1 and Schwinghehel is present. This design is in particular selected, if connecting in such a way the Umschnürungsmittelenden is done via welding. The heating lamella driven between the Umschnürungsmittelenden can back-shift then to finished heating process without damage of the appropriate Umschnürungsmittelabschnitte. After these Zurückverlagerung and in press position of stepped printing cheek only the spring action of the tappet appropriate pressure is then expenditure-practiced, which leads to no unfavorable squeezing of the Umsehnürungsmittelendeu. A remark example of the invention is described on the basis the designs. It shows: Fig.1 an opinion against the device, Fig.2 the klappfigürliche side view from left to Fig.1 and Fig.3 to 8 a cutout of the upper range of the device in different working positions with the Umschnüren of a package. The device possesses the housing --1--. Within the lower range the housing stores --1-- the drive shaft --2--. This carries within the housing not represented cam discs as well as at the front side the housing --1-- cam disc present --3--. The cam disc --3-- is with a turn slot --4-- provided, in which the assessment roll --5-- around the pin --6-- stored lever --7-- intervenes. The free end of the lever --7-- forms a Mitnehmerschlltz --8-- out, that of a tap --9-- the support --10-- one intersperses. To the guidance of the support --10-- serve horizontal-arranged stem guides --11--, of the carriage shiftable in the height --12-- go out. To the guidance of the slot --12-- serve the housing-stationary bars --13 and 14--. The misalignment of the carriage --12-- happens by means of the control disk --3--, which possesses a not represented turn slot on its back, in which the assessment roll --15-- the einarmigen lever --16eintaucht. The lever --16-- stores around the axle --17--. A steering wheel --18-- the misalignment of the lever transfers --16-- on the carriage --12--. The support --10-- is carrier of the grip arm --19--. Components of the same are the grip arm retaining plate --20-- and this assigned clamping jaw --21--. The Greffer retaining plate --20-- is equipped with one transverse to the Umschnürungsmittel --22-- aligned notch --23--, that the accordingly formed rib --24-- the clamping jaw --21-- faces. Furthermore the support carries --10-- the printing cheek --25--. From the lower surface the tax tap goes to the same --26-- out, a guidance block --27-- the support intersperses. For the twist lock those serve the printing cheek reciprocally the tax tap --26-- guide pins present --28--. By means of a not represented feather/spring the printing cheek is toward the guidance block --27-- spring-tensioned, thus in Öffnungsriehtung. The printing cheek --25-- forms for the Greffer retaining plate at its upper, --20-- course-turned edge the measurer longing oaths --29-- out. Concerning the printing cheek --25-- it concerns the lower printing cheek, that the upper printing cheek --30-- faces. Represented tax proceeds do not permit the upper printing cheek --30-- a misalignment in Pfeilriehtung x. Within the range between upper and lower printing cheek the heating lamella shiftable transverse to the Umsehnürungsebene 3s extends --31--. The upper printing cheek --30-- is carrier of a shim --32--. The clamping slidegate valve is assigned to this --33--, which aforementioned parts the volume clamp --34-- represent. The clamping slidegate valve --33-- is for his part shiftable transverse to the Umschnürungsebene. Of the clamping jaw --21-- a Führungssteg goes --21 '-- out, that the Durehführöffnung --35-- for the Umschnürungsmittel --22-- forms. The lower printing cheek --25-- and the Greffer retaining plate --20-- are likewise in Pfeflrichtung x shiftable. Hiezu goes from the guidance block --27-- a tap --36-- to. This is subjected to a cam controlled lever --37--. Then is still another further cam controlled balance beam --38-- planned. The free end of 4s --89-- leads the tappet --40--. A transverse tap --41-- the same intersperses the lengthwise slot --42-- the balance beam --38-- and limits the misalignment way from a compression spring --43-- loaded tappet --40--. R-S results the following impact: In Fig.1 and 2 the starting position of the device is represented. A package --44-- is umschnürt finished and still lies on the machine table. The Umschnürungsmittelende --22 '-- is from the grip arm --19-- held. After a certain partial turn of the Steuerseheiben in direction of arrow y the position is reached in accordance with Fig.3. Occasionally however the turn is interrupted. In this position the upper printing cheek has itself --30-- from the Umschnürungsebene in direction of arrow x back-shifts, so that the finished umschnürte package can be presented be removed and a new. The lever --7-- has in accordance with Fig.3 the support --10-- on the stem guides Nr.347862 --11-- the carriage --12-- shifted. Thus is the grip arm --19-- and also the lower printing cheek --25-- on the other side of the Umschnürungsstelle. In order to make this transverse misalignment possible, is the tappet --38-- upwards avoided. In accordance with Fig.3 the tap extends --36-- in the Sehwenkbereich of the cam controlled lever --37--. Furthermore is also the upper printing cheek --30-- again into their starting position in accordance with Fig. 1 driven. After a further certain turn of the drive while --2-- the position is reached after Fig.4. The lever --16-- has the carriage --12-- upward shifts and concomitantly the support --10--. The Greffer --19-- is on height of the upper printing cheek --30-- driven. The Umschnürungsmittelende --22 '-- is against the shim --32-- stepped and becomes by the clamping slidegate valve moved against the direction of arrow x --33-- between these two parts held. In this instant a double wedging is present, on the one hand by the Bandklenune --34-- and on the other hand by the grip arm --19--. After a further step turn the position is present in accordance with Fig.5. The grip arm --19-- and the lower printing cheek --25-- have themselves over the lever --7-- still continues to shift. At the same time the cam controlled lever subjects --37-- the taps --36--, which a misalignment of the printing cheek --25-- and also the grip arm retaining plate --20-- according to (to the consequence) has. This misalignment of the grip arm retaining plate arranged transverse to the Umschnürungsebene --20-- leads za opening the grip arm, so that the Umschnürungsmittelende --22 '-- exclusive of the volume clamp --34-- is held. The Umsehnürungsmittel can in this position of the not represented Umschnürungsarm of the machine completely around the package --44-- and become D are put nn by the opening --35-- the clamping jaw --21-- led. The Umschnürungsmittel already is into the range between notch --23-- and rib --24-- stepped. Becomes subsequently, after a further Tefldrehung of the drive shaft --2-- the position in accordance with Fig.6 reaches. The grip arm --19-- and the lower printing cheek --25-- were now again back-shifted by means of the cam controlled lever --7--. Is the tap --36-- from the effective range of the lever --37-- stepped. The lower printing cheek --25-- and the hit retaining plate --20-- itself could] agern against direction of arrow x. Is the grip arm --19-- stepped into clamping position. ] Agerung the grip arm retaining plate --20-- and the pressure plate --25-- taken place via the spring-tensioned pressure pin --45--. In the position in accordance with Fig.6 is the carriage --12-- again downward-moved by the appropriate SteuermitteI. Fig.7 shows the next intermediate position. The lever --7-- has now the support --10-- completely to the other side shifts. The carriage is simultaneous --12-- again raised, so that itself now the grip arm --19-- beside the upper printing cheek --30-- finds. The servo-controlled heating lamella --31-- extends between the Umschnärungsmittelende --22 '-- and the appropriate section of the Umschnürungsmittels --22--. Furthermore is the tappet --40-- over the cam controlled balance beam --38-- brought in action, which tappet --40-- the tax taps --26-- the printing cheek --25-- subjected and these toward the junction point loads. After a certain heating-up time of the Umschnürungsmittels designed as plastic volume the position is reached after Fig.8. The heating lamella --3I-- then the lower printing cheek is in back-shifted position and --25-- the heated Umschnürungsmittetabschnitte brings in splicing tape. However the carriage has itself --12-- over ehlen consciences ask downward shifted. The support beweit itself --I0-- with. The printing cheek --25-- remains itself during this downward misalignment in its pressure position according to the not shifting balance beam --38-- and the tappet --40--. Under the downward misalignment of the support --10-- likewise a downward movement of the grip arm steps --19-- on” whereby the Umschnürungsmättel --22-- of the knife edge --29-- the printing cheek --25-- splits becomes. Thus becomes from the grip arm --19-- Umschnürungsmittelende held --22 "-- for the next Umschnürungsvorgang obtains. In the position in accordance with Fig.8 is however still the other Umschnürungsmittelende --22 '-- of the Bandldemme --34-- held. The release of the Umschnürungsmittelendes --22 '-- happens only with further Telidrehung of the Antrfebswelle --2-- into the starting position in accordance with Fig.l. The clamping slidegate valve drives --33-- the volume clamp in direction of arrow x back. Then however the appropriate UmschnürungsmittelabschDitte is already connected.
