^ Machine for the production of Am substantially cylindrical plant dumpersi ^ p *

The innovation relates to a machine for producing essentially cylindrical plant stumps, which from a filling material and a shell surrounding it.

The term "filler material" encompasses material in which seeds germinate, at least for a period of time and can take root.

The term “continuously” is understood in particular to mean “continuously”, but this term also includes consecutively hand-set sections.

For the production of plant stumps of the aforementioned The way they e.g. DE-OS 30 49 576 shows, it is known from U5-PS 3 456 386, filler material in the form of a feed pre-produced endless conveyor strip. The strand material can e.g. B. from lignocellulosic endless material exist, this strip-shaped material continuously before the formation of a stump tube is twisted helically to create a more round strand. The filler strip is with brought together in an endless spermatic cord and wrapped together in a strip of paper. Of the so educated Individual plant stumps are then cut off.

The task on which the innovation is based is to improve, in particular, plant stumps of the type mentioned above cheaper to manufacture.

According to the innovation, the machine mentioned at the beginning is thereby characterized in that a machine frame

The spreader 11 according to FIG. 2 is made of synthetic fibers according to the innovation existing filling material supply 12 in divided into two partial supplies: into a supply belt guided on a controlled drivable via rollers 25 and 30 31 located large supply 12a and in a smaller supply 12b, from the large supply 12a filler material with loosening by a rotating paddle roller "? 2 receives and from which a driven extractor 33

removes filler material in the form of a rotating roller 36 equipped with needles 34. One also studded with needles Counter-rotating back combing roller 37 ensures a constant layer between the needles 34 on the roller 36. A rapidly driven beater roller 38 is used to knock out the filler fibers from the needles 34 and for transfer to a driven, provided with a corrugated surface spreading or Winnover roller 39, which as scatter to scatter the filling material fibers on a guided over rollers 41 and 42, moving Non-woven cloth 43 is used. The one formed on the non-woven cloth 4.J. Fleece 13 has a small height relative to its width (see Figure 2) and is homogeneous, which is good for the uniformity of the subsequently built up filler fiber strand is important.

Below the fleece cuchea 43 is the rod former in the form of the funnel-shaped channel 14 with the Side walls 15a and 15b, on the bottom and on the side walls of which a conveyor in the form of a strand conveyor belt 56 runs. This band can, if there is an increased direction of the filling material 3 is required, air-permeable be; then under him the channel bottom 57 is provided with air passages 55, which connect between a Form vacuum chamber 58 and the strand conveyor belt 56. The vacuum chamber 58 is via a line 59 with ei nem vacuum generator 61, z. B. a fan, ver bound * The channel 14 can also have a rectangular cross-section with parallel side walls 15a and 15b, so that the strand conveyor belt 56 is guided just at the bottom of the channel. The vacuum chamber 58 can be omitted if the friction between the strand conveyor belt 56 and the filler material 3 is big enough.

The millet conveyed from the fleece cloth 43 into the channel 14 Filler fibers are fluffed up and from a relatively narrow, deeper filler fiber strand 62 conveyed away the strand conveyor belt 56 perpendicular to the plane of the drawing.

If the surface of the filler fiber strand 62 is to be smoothed, an equalizer can be used, as is known from GB-PS 1 365 517 and there- is only indicated by the identification of the equalization point 63.

The possibly supplied fertilizer particles are evenly distributed in the fiber strand formed.

Dosing disc 66 is equipped with a drive motor 72 (Figure 4) to drive the machine, that is to say in particular the strand conveyor belt 56, the strand conveyor 22; the hose former 23, the cutter 28 and the deflector device 29 synchronized so that a seed 4 is placed on the filling material fiber strand 62 in such a way that it is at a certain distance from the later separation points at which the strand is cut and the the end faces 8 and 9 in Figure 1 correspond to lie comes.

By increasing the number of recesses 67 in the metering disc 66 can the feeder 16 · for the seeds 4 be modified so that several seeds can be placed in a Pfianzstumpabschnitt.

If the plant stumps are only to be provided with seeds after production, then of course the is not required Dosers and feeders 19.

The actual line connects to the line conveyor 22 J Hose former 23 through which the wrapping material

rial strips 2 together with the FuH-mätefiäl-Faserätrang lying on it 62 drawn through by the endless format belt 73, which acts as a conveyor belt will. Here, the filler-fiber strand is initially increasingly compacted in the format 24, with the wrapping material strip around the strand during the compaction so is laid around that only one edge protrudes upwards, This edge is through the bucket 26, 'of the the glue container 35 and a glue application disk 40 are visible are glued. Details of the format and buckets are shown in US Pat. Nos. 3,915,176 and 3,380,352.

Subsequent to the gluing, the glued seam is through a heated bridge for faster glue setting heated, as is apparent from US Pat. No. 3,507,288. For cutting off finished plant stumps from the continuously conveyed plant stump hose 20 is used then the tailor 28, from the individual or double-length plant stumps 1 are cut off. At the tailor depicted, of whom the US-PS 3 176 560 shows details, the cutting knife is made by inclining a circumferential: knife carrier when cutting moved with the planting hose 20 in the direction of its longitudinal axis. The knife is then sharpened as it moves backwards. Another embodiment of a cutter with a reciprocating knife carrier is the US-PS 3 241 413 can be found.

The deflecting device 29, of which US Pat. No. 3,602,357 shows details, consists essentially of a

An eccentrically rotating accelerator cam 77, which is also connected to the machine and the Drum is synchronized, each cut plant stump 1 detects on its surface, accelerates it compared to the following plant stump and promotes it in a trough 74 of the drum 76. Here, the Plant stumps deflected in the deflection zone 76 in such a way that it from a movement in the direction of its longitudinal axis in a direction of movement is transferred transversely to its longitudinal axis.

The smaller supply 12b, which is kept constant and constantly compressed by the rammers 46, becomes continuous Filler fibers 3 removed from the roller 36, the removed layer from the needle roller rotating in the opposite direction 37 is limited. The filler material fibers knocked out of the needles 34 of the roller 36 by the beater roller 38 arrive at the scattering and winnover roller 39, which the filler material fibers as a shower 13a on the non-woven cloth 43 scatters and thereby builds up the fleece 13.

In this case, solidifiers can be sprayed through the nozzle 44 into the shower 13 a and fertilizer particles 71 can be sprinkled onto the fleece 13 will.

The filling material fibers of the fleece 13 are continuously transferred from the fleece cloth 43 to the strand conveyor belt 56 in the Channel 14 shuddered, on which the Forms filler fiber strand 62 and is conveyed away. If necessary, the strand will adhere to the strand conveyor belt increased by means of suction air and the strand surface

The seeds 4 are taken over into the receiving troughs 67 of the metering disk 66 and continuously conveyed to the filling material fiber strand 62 moving on the strand conveyor belt 56, on which they are placed at the correct distance to the later interfaces. Thereupon the filling material fiber strand 62 provided with seeds is continuously transferred by the strand conveyor belt 56 onto the wrapping material strip 2, the strand conveyor 22 engaging the filling material fiber strand at the top supporting the transfer by pushing. The filling material fiber strand 62 and the wrapping material strip 2 are pulled together and continuously from the format tape 73 through the tube former 23. Here, the filler material fiber strand is first compressed in format 24 and the wrapping material strip 2 - apart from one edge - placed around the strand. The edge protruding upwards is glued from the glue application disc 40 and the plant stump hose 20 is closed by pressing down the glued edge can be cut off by the cutter 28.

The cut, axially moved plant stumps 1 are accelerated by the accelerator cam 77 and
