Container for filling with substantially cylindrical Seedlings

The invention relates to a container for filling with 1m substantially cylindrical seedlings, each consisting of of a filler material that contain at least one seed may, surrounding HUIIe in which the seeds or Plant part are brought to germinate. The term "filler material" includes material in the seeds - at least for a certain time - can germinate and take root. It can be peat, potting soil or similar substances with and level fillers (e.g. Foams) and fertilizers. The filling material can contain a seed or can be used to hold parts of plants, like cuttings, be suitable e.g. B. by providing a recess.

It is known from DE-OS 30 49 576 to connect cylindrical seedlings, such as those produced by the method known from US Pat. No. 3,456,386, by means of a spacer band and to germinate the seeds at the desired time. After cultivation, the seedlings are then planted out in the field in a manner not shown, the spacer band determining the distance between the seedlings.
The object on which the invention is based consists in

Empty containers 2 (hereinafter referred to as "trays") are in f / q. on a blank space stetion 1 on standby and become by a lifting mechanism 3 with the drive that executes a lifting and forward movement in the direction of arrow 5 4 successively transferred to a lowering conveyor 7 (step conveyor) that can be driven step by step by a drive 6, of the one tray 2 transferred onto it step by step into a further vertical filling level F at a filling station 8 promoted by. The filling station 8 receives seedlings 9 (Details in Figure 2) from a feed conveyor in the form a tape 11 is successively fed in transversely axially perpendicular to the plane of the drawing and in an accumulation plane A. (Fig. 4) on receptacles (troughs 12) of a row former arranged directly above the belt 11 in the form of a suction head 13 accumulated to form a gapless row 10 of equidistant seedlings 9. The troughs 12 protrude Channels 14 in connection with a space 16 in which there is negative pressure. After forming the series that consists of a defined number of equidistant seedlings 9 exists, a drive 17 lifts the suction head 13 into the transfer level "^ !!! an amount that is slightly larger than the diameter of the seedlings, so that the wider incoming seedlings 9 are not disturbed when they get under the suction head 13. One of a drive

18 driven transfer means in the form of a ram

19 transfers the entire row 10 through a mouthpiece 21 in the tray 2, each planting in one Receives recording, which is separated from the neighboring recordings by partitions. The drive then lowers 6 the tray 2 by one step, which corresponds to the distance between two rows of plants, while the drive 18 moves the plunger 19 back and the drive 17 moves the suction head is lowered back to its original position via the belt 11, in which it collects another row of plantings.

In this way, the tray 2 becomes consecutive formed rows of plantings filled.

After a certain number of rows of plants has been transferred, the drive 4 transfers the following empty trench onto the lowering conveyor 7. Reaches the filled tray the level of a full tray station 22, it is conveyed by a conveyor belt 23 in FIG Direction of arrow 24 conveyed away. The conveyors 3, 4 and 23 represent both conveyors and discharge conveyors for the trays 2 as well as storage for the empty or full trays. The tray 2 is what is not in Figure 1

Xb is visible, honeycomb through horizontally and vertically

running partition walls divided, with the horizontal walls the individual horizontal rows of plants from each other separate while the vertical walls separate the seedlings in a row. The recordings formed in this way the trays 2 can be round, triangular, rectangular (especially square) or polygonal, e.g. B. hexagonal be. If the recordings are hexagonal, so can they can be designed like the walls of honeycombs.

Figure 2 shows a planting 9 with a shell 26, the substantially cylindrically shaped filler material

27 made of peat, organic fibers, potting soil or the like or mixtures thereof. In itself is used as a filler material any material suitable in which a seed

28 can germinate or develop roots. The shell can made of material that rots quickly in the ground, preferably paper. But also other materials, e.g. B. suitable plastics can be used. Relatively durable plastic can also be used, if rapid dissolution of the envelopes is not required or desired.

In Figures 3 to 5, the suction head 13 is to be collected and lifting of rows of plants together with drives explained in detail.

The suction head 13 is movable up and down that a Maintain a parallel position with respect to the conveyor belt 11 remain. The movement of the suction head 13 is initiated by the piston of an air cylinder 31, which is rotatable is attached to part G of the machine frame and the power element of the drive 17 (Figure 1) forms. This rotary movement is in turn supported by a piston rod 32, a spindle 33 and two rotatably mounted Transfer levers 34 to suction head 13. The levers 34 are mounted by means of bolts 36. The connection between the suction head 13 and the levers 34 take place through a hollow bearing spindle 37, which is firmly connected to the levers 34 and is provided with a temporary bearing. The suction head 13 is rotatably mounted in this way on the hollow bearing spindle 37, which acts as a suction line 38 for the suction air serves (see Figure 4). The suction line 38 is connected to the suction side via a flexible line (not shown) a fan, also not shown, in connection. To the suction line 38 with the vacuum chamber 16 of the suction head 13, an opening 41 is provided in the hollow bearing spindle 37, which is dimensioned so that with each movement of the lever 34 and the corresponding slide bearing that is in the The suction head 13 remaining in the lower layer is provided, the full cross section of the suction channel V for the suction air preserved. A recess 42 is provided opposite the opening 41 in the hollow bearing spindle 37. The recess 42 corresponds to an additionally provided air inlet 43, which is involved in the to-and-fro movement the lever 34 takes part.

The underside of the conveyor belt 11 is supported on a support plate 44 (see also FIG. 5). This platen sits between frame parts 46 and 47, in which pulleys 48, 49 of the conveyor belt 11 are rotatably mounted are. The end 51 of the suction head 13 facing away from the hollow bearing spindle 37 is in levers 52 and according to FIG 53 pivotally mounted and removably supported by slot 54.

The levers 52, 53 are on the frame parts 46 and 47 p by means of hinge pins 56 or 57 (see also Figure 5)

'4. pivotally attached. The upper lever arms 58, 59 of the

J form a lever 34 located in the area of the bearing spindle 37

15 with the levers 52 and 53 a parallel guide for the k Suction head 13.

H The suction surface of the suction head 13 is used as troughs

U ₁ trained receptacles 12 for the seedlings 9 formed.

J These receptacles 12 are accessible via channels 14 (Figure 1,

ξ 20 Figure 5) connected to the negative pressure chamber 16. The recording '■ i: Men 12 form the top wall and the frame parts 46

The operation of the device according to Figures 3 to

5 is the following:

The conveyor belt 11 promotes the seedlings 9 in an irregular manner Follow to, and the seedlings are one after the other from the receptacles 12 or their suction slots 14 sucked in. As Figure 4 shows, there are already four seedlings 9 have been sucked in, which have the same distance 15 from central axis to central axis. The fifth The seedling is still from the fifth shot 12 removed, but is already under the action of the air flow, which is effective in the direction of arrow 62. At the beginning of the action of the air flow on the plant

Stw .: Fill in seedling container and excretion Hauni file 1765 - Bergedorf, April 18, 1984

This becomes ling due to the fact that it is carried along by the conveyor belt 11 moves in the direction of arrow 62 and approaches the associated receptacle 12 at an accelerated rate As it approaches the associated receptacle, it is lifted off the conveyor belt 11 by the air flow and with it a relatively high speed resulting from the air flow is conveyed to its receptacle 12.

The process described above is repeated in tt --- r sequence, until all the seedlings are sucked into the receptacles 12 of the suction head 13.

To move the in the manner described above in the

Gapless row of plantings formed on accumulation level A in a higher transfer level ^ the air cylinder 31 is applied in such a way that it pulls the piston rod 32 into itself. By this movement of the piston rod 32 pivot the levers 34 in the direction of arrow 63. This makes the suction head 13 parallel to itself raised. The push rod mentioned in FIG. 1, not shown in FIGS. 3 to 5 for reasons of clarity 19 then pushes the seedlings of the raised row in the direction of their longitudinal axis from the suction head 13 and promotes them in the recordings of the tray 2 (Figure 1). After the row of plants has been transferred, the suction head 13 is moved back into the accumulation plane A shown by reverse movement of the piston rod.

During the transfer of a row of plantings 10 from the suction head 13 in the trays 2, the seedlings 9 further conveyed by the belt 11 can under äen Running suction head. After it has been lowered, the first seedling automatically reaches the first receptacle 12 of the suction head 13, because the negative pressure is highest at this trough. If the recording is carried out in the manner described above with a When the seedling is occupied, the adjacent open receptacle has the highest negative pressure. If this recording is also occupied,

Stw.t seedlings-fill-container-excretion Hauni file 1765 - Bergedorf, April 18, 1984

so the maximum negative pressure moves to the next open one Recording until this is also occupied, etc. When the negative pressure has reached the last intake (in the direction in which the seedlings are fed the first) has been reached and this is occupied, the resultant change in the negative pressure conditions detected in the vacuum chamber 16 by a vacuum switch, not shown, and the upward movement as well triggered the flyover of the series. The seedlings deposited in this way lie in the receptacles of the tray 2 one above the other, as shown in FIG.

When the suction head 13 is raised, the air outlets arrive 42, 43 (FIG. 4) one above the other, so that the negative pressure is reduced when the seedlings 9 are transferred into the container 2 or is eliminated. Depending on the nature of the seedlings, it can also be advantageous to use the seedlings to slide off the suction head 13 when a negative pressure is active, the air passages 42, 43 then being omitted.

FIG. 6 shows a planting 9 ¹ , consisting of a filling material 27 * surrounding envelope 26 ', which instead of a seed 28 (FIG. 2) has a recess 29 for a seedling, e.g. B. has a cutting. Such seedlings can also be automatically filled into containers with the method and the device according to the invention.

In FIGS. 7 and 8 there is a container 2 without the reinforcing ribs still indicated in FIG. 1 on it Shown outside. The container has square receptacles 82 for receiving seedlings 9, 9 '. These recordings are formed by a grid of hori-

Stw .: Fill in planting container - excretion Hauni file 1765 - Bergedorf, April 18, 1984

zontally extending partition walls 83 and vertically extending Partitions 84. The partitions have the purpose of

Roots of germinated from seeds or cuttings Separate plants from one another. On the underside 86, which is the filling side in FIG. 1

is turned away, the recordings 82 have round openings 87, through which water can drain. If necessary, slides (not shown) through the openings 87 in the receptacles 82 for removing the seedlings 9, 9 ' be pushed out of the recordings.

To prevent the seedlings 9, 9 'from falling through the openings To avoid 87, a support edge 88 is provided at the bottom of the receptacles 82.

FIGS. 9 and 10 show a variant of the container according to FIGS. 7 and 8, in which a spacer 89 consisting of four webs centers a planting 9, 9 ¹ in the middle of a considerably larger receptacle 82.
