Definitions
- the invention relates to a filling machine with a device for the pneumatic conveying of the filling material through a rigid filling pipe firmly connected to a weighing device into a valve bag which can be pushed onto the filling pipe, the filling pipe including an angle between 0 ° and 35 ° with the horizontal.
- the invention has for its object to improve a filling machine of the type mentioned so that an improved emptying of the filling tube is achieved at the end of the filling process.
- This object is achieved in that the inner cross section of the filling tube has a much greater width than height.
- a rectangular, semicircular or elliptical cross-section can be considered as cross-sectional shapes in the filling tube according to the invention.
- the filling tube has the greatest width at its bottom, which is the case with filling tubes with a rectangular or semicircular cross section.
- the preferred embodiment is a fill tube with a rectangular cross section.
- the ratio of the width to the height of the inner cross section of the filling tube is preferably about 2: 1.
- this filling tube led to a reduction in the deposit of 30% compared to a filling tube with a round inner cross cut.
- the filling pipe can be constructed with two shells.
- the space between the two shells can be used to remove the compressed air escaping from the sack.
- the bottom of the filling pipe can be designed as a ventilation floor. In this way, a type of fluidized bed can be created with which any remaining amount remaining in the filling pipe can be discharged completely.
- the air supply lines can also be accommodated in the space between the two shells. The previously common, heavily dust-producing blow-out devices with mostly unsatisfactory residual emptying of the filling tube can thus be dispensed with.
- the outer wall is formed by an inflation hose which automatically forms the required round outer wall when it is inflated with compressed air or the like.
- the filling machine shown in Figure 1 has a support frame 1 to which a bag chair 2 is attached as part of a weighing device.
- a filling tube 3 is connected to the arrangement movable with the bag chair 2. Via a rubber piece 4 effecting a decoupling of the weight of the filling tube 3 from the support frame 1, the filling tube 3 continues up to a storage cylinder 5, into which the continuation of the filling tube 3 opens.
- the filling tube 3 is inclined obliquely downwards, its inclination roughly corresponding to the inclination of a bottom 6 of the storage cylinder 5.
- a plurality of compressed air chambers 7, which are supplied individually with compressed air hoses 8, are arranged below the base 6. The pressure in the compressed air lines 8 can be adjusted via the adjusting regulator 9.
- a shut-off device 10 At the upper end of the storage cylinder 5 there is a shut-off device 10 with which the storage cylinder 5 can be separated from a supply line 11 from a storage bunker (not shown).
- the connected to the weighing device front end of the I filling tube 3 is connected to the bag chair 2 via a mounting bracket 12, to which a pressure stamp 13 is attached above the filling tube 3, which is used to hold the valve pushed onto the filling tube 3 of a (not shown) ) Valve bag on the filling tube 3 is used.
- FIGS 2 and 3 clarify the structure of the filling tube 3 with the devices attached to it.
- the filling tube 3 is attached at an angle of approximately 20 ° to the horizontal, pointing obliquely downward on the outer wall of the storage cylinder 5 and opens into the latter with a through opening 14 which has exactly the cross section of the filling tube 3.
- the filling tube has rectangular inner walls 15, the width of its inner cross section being approximately twice as large as the height.
- the inner wall 15 of the filling tube 3, which forms the bottom, which is horizontal in cross section, is aligned with the bottom 6 of the supply cylinder 5. Below the bottom 6, the associated compressed air chamber 7 is indicated in FIG.
- the front end of the filling tube 3 has the rectangular inner cross section, which is illustrated in FIG. 2a with a section along the line AB in FIG. 2.
- a protective plate 16 is attached on the bottom inner wall of the filling tube 3.
- These ventilation lines 17 are used to discharge the conveyed air pumped into the sack with the contents from the sack.
- the outer wall of the filling tube 3 has two annularly formed and spaced apart grooves 18, between which a chamber 19 is formed. In the grooves 18 two ends of an inflation hose 20 are fixed in a ring-shaped manner, which spans the chamber 19.
- a compressed air supply line 21 opens into the chamber 19, through which the compressed air required to inflate the inflation hose 20 is pumped into the chamber 19.
- the part of the filling tube 3 described so far is connected to the weighing device via the mounting bracket 12. It is followed by the soft rubber piece 4 towards the supply cylinder 5, with which the front part of the filling pipe 3 is decoupled in weight from the remaining part of the filling pipe 3.
- the part of the rubber piece 4 pointing towards the supply cylinder 5 is fastened to the support frame 1 of the filling machine. It is continued by a further piece of rubber 21 which merges into a fixed line piece 22 attached to the outer wall of the supply cylinder 5.
- the rubber pieces 4, 21 and the line piece 22 all have the rectangular inner cross section shown in FIG. 2 a, so that a smooth flow channel with a rectangular inner cross section is formed for the filling pipe 3.
- the rubber piece 21 can be partially or completely compressed by means of two pressure pistons 23. Due to the partial compression of the rubber piece 21, the quantity of product passed through the filling pipe 3 is reduced in quantity, that is to say a so-called fine flow is formed. Serves in a known manner; the fine flow for the remaining filling of the sack largely filled with a coarse flow. By completely squeezing the rubber piece 21, the flow is completely interrupted and the filling of the sack is ended.
- the emptying of the filling pipe is further improved by the fact that the bottom of the filling pipe 3 is at least partially constructed as a sieve, under which a compressed air line 25 ends (cf. FIG. 4a). As a result, the tendency of the filling material to settle on the essentially flat bottom is still reduced by the compressed air flowing through the sieve bottom 24.
