Driving and device for filling valve bags

χ *

The invention relates to a method and a device / for filling valve sacks and keeps track of the difficulties encountered before aging, such as the impellers or similar problems that have arisen when filling the open air. remove. It is particularly suitable for pulling Gto t, Are I9a.es tends to bake. Such a hitherto unpopular property has been made nutsable. The flaw of the invention consists in the fact that the goods are brought to the sack by means of conveyor belts.

Ui e l'ülldüse. 2σ is vertically displaceable in the guide 2.5 of the machine part 15 and can be lifted into the dot-dashed days by means of the handle 24 and the scissors 25. Then the sliding surface 26 is in the path of the Gutstranges and allows the G-ut in ien i-hlauftrichter fall 27 from which it ß & ger line 28 back into the feed hopper la zuräckge is introduced. The Jüse 2o is brought into this position while there is no sack 22 on it. JSs can be seen, including means, which only allow them to assume the lower operating position shown when the bag 22 is attached, for example by arranging an electrical contact interrupted by the attached bag or an ultra-red light beam that controls the excitation of a magnet that lifts the sleeve.

uas conveyor belt 11 only has tensile planes 29 for transmitting the output from drive shaft 13 in its central part In addition, its lateral parts are free of such and consist of highly elastic, longitudinally, lightly elastic, stretchable, Yerkstoff. This will fold over the side. Edge parts of the bend it 11 facilitates and a LäLngsdehnuiig of the tendons 2Q Terhütet, whereby the life of the band 11 is considerably extended »,

Lan already has the bulk material in a flow considerably larger ■ cross-section than that of the üinfullventils, on one having an approximately horizontal part, with a large

In contrast, according to the invention, the 5xut given to the tape becomes one. Strands or rods so compressed that it retains this shape when the belt is bent and is pushed into the Wentilsaok through the jg'üllSffmmg.

In the exemplary embodiment shown in Fig. 6-8, the syliii & rl & ßheEt bulb pairs 3o, 51 and 32 are in the machine frame stored in such a way that they uporkippea the lateral, again ran longitudinal tendons, free ropes of the conveyor belt 34, so that leave a right-angled-eji cross-section according to fig. "Above the. Volume 34 there is a second endless Bamsd 35 TorgeseiiL, daa its drive τοη the in the opposite sense revolving roller 36 receives. .This upper belt 35 runs from its roller 37 initially obliquely downward onto the guide roller 38 and then parallel to the middle part of the lower band 34. It is therefore narrow that it is between its folded-up rare parts can run along *

The material discharged from the feed hopper 39 is thus here compressed onto a strand with a square cross-section the pressure is exerted by the band 35 also τοη above.

The coaming 4 ©> arranged in front of the ends of the two belts 34 and 35 which is shown here for the sake of simplicity,

however, it can also be designed to be liftable, as in the most exemplary embodiment, is bent downwards and ends in this oblique sighting into the valve bag 41 attached to it, the one on it in the usual quiet way, the jQemme 42 held tight

In this exemplary embodiment, the shower 43 * is provided above the band a 34 between the feed funnel 39 * and the roller 37, in order to be able to shower, moisten or wet the product if necessary, as well as a heating device 44 _S to warm it up before pressing it together if necessary *

Fig. 9 and Io show cross-sections of a different embodiment accordingly (Leu lacing the Fig. 7 and 8 "read! Conveyor belt 5ο is provided here on its / back with longitudinal grooves 51, which facilitate a flat folding of its side parts (see Fig. 11). The upper conveyor belt 52 is wider than the distance between the side parts of the lower belt 5, which are completely folded down in the vertical position, and it does not enter between them, but rather their hands are facing its running surface here.

In the embodiment shown in Fig. 12, the two strips 6o and 61 are finally bent together by the pairs of rolls 62 and 63 or 64 and 65 to form semicircular cross-sections, which are finally united by the last pair of tubes 66 to form a full cross-section, the two lateral ones , each other
