    The threading of the sleeve from the top end towards the root end is blocked by the positioning means.
    THE INVENTION IN BRIEF In order to provide an automated application of sleeves, this problem is solved by a device whose distinctive features are set out in claim 1.
    Advantageous embodiments are set out in more detail in the dependent claims.
    Briefly, there is provided an apparatus for applying a tubular sleeve to a plant plant standing in a culture cell contained in a cassette consisting of at least one row of culture cells, which device comprises positioning means for positioning the cassette relative to a sleeve holder, which sleeve holder is movably arranged and driven for a reciprocating movement in the longitudinal direction of the plant for threading a sleeve so that the sleeve extends around the plant for at least a part of its length. A plant rectifier included in the device has a set of rulers which in pairs extend side by side and are assigned drive means with which the rulers are rotatable about an offset or rotating axis offset against one longitudinal edge of the ruler to a horizontal extent where the rulers support the plant in the path of the sleeve holder. rotatable to a vertical extent in which the rulers extend outside and on either side of the path of movement of the sleeve holder.
    The solution allows the sleeve holder with the sleeve supported therein to be lowered over the plant without being obstructed by the rulers.
    In an advantageous and preferred embodiment, the rulers are arranged to be passively carried by the advanced sleeve holder and rotated to the lateral position. The function can be provided in a mechanical solution comprising a releasable locking mechanism, and can alternatively be realized by a hydraulically or pneumatically acting rotating member at which the working pressure is closed to allow the passive rotation of the rulers. In the illustrated and preferred embodiment, the rulers are rotated to the supporting horizontal position by means of a pneumatic rotating member and a gear transmission, a valve being provided for venting the pneumatic circuit in synchronization with the movement of the sleeve holder in the direction of the cassette. It is advantageous if at least two pairs of rulers are arranged in different planes or levels, and aligned vertically over each other. This provides support for the plant at two or two levels along the length of the plant, thereby straightening the plant and facilitating the application of the sleeve while reducing the risk of mechanical damage to the plant. In the shown and preferred embodiment, for these purposes, three pairs of rulers are arranged in different planes.
    The individual ruler is a disc-shaped and elongate element with parallel longitudinal edges, and has a length adapted to the cassette. A shaft journal extends from the end of the ruler substantially as an extension of one longitudinal edge, forming a pivot axis about which the ruler is rotatable between a substantially vertical rest position and a substantially horizontal working position. Opposite longitudinal edge is formed with recesses forming receiving positions for each of the plants in the row of plants. These recesses, which are evenly distributed in the length of the ruler, are suitably U- or V-shaped with a widened mouth at the edge of the ruler, thereby providing a guide of the plant or its stem towards the bottom area of the recess when the ruler is turned to the working position. This achieves a positioning of the plant in both directions of the cassette, or in other words both in the X-direction and in the Y-direction.
    In a preferred embodiment, the rulers within each pair of rulers are further arranged in different but adjacent planes, and have an overlapping width in such a way that corresponding recesses in the two rulers together form an all around limited opening for the plant when the rulers in the working position occupy the horizontal the stretch.
    It is further preferred that at least the top pair of rulers is adjustable in height, i.e. in the longitudinal direction of the plant. Based on a length measurement by means of sensors, the top rulers can be adjusted to the area of the top end of the plant for an accurate positioning of the top in the path of movement of the sleeve holder, in a substantially centered relationship to the sleeve which is releasably supported in the sleeve holder.
    Advantageously, however, all rulers can be adjustable in height in order in this way to enable an optimal distribution of the support points in the longitudinal direction of the plant. In this embodiment, the rulers can be controlled to stretch the plant in its longitudinal direction, by first turning the rulers to their supporting position in their lowest position and then lifting them to a higher position determined on the basis of a measurement of the plant length.
    The rulers are in their longitudinal direction movably mounted in a horizontal running guide which is supported in a frame which also comprises means for receiving and fixing the cassette. By means of a drive means, such as an air cylinder, the planter can be inserted with rulers horizontally between rows of seedlings from a starting position next to and above the cassette.
    An alternative design comprises a plant rectifier arranged stationary in the frame and a movable receiving position with associated drive means for the cassette.
    Furthermore, each pair of rulers is rotatably mounted by its shaft journals in a respective bearing unit which comprises a rotary motor, such as a pneumatic rotary motor, and a gear transmission with which the rulers are linked for simultaneous rotation in mutually opposite directions of rotation.
    The storage units of the rulers are further individually and / or jointly movably mounted in a vertically oriented guide, and associated drive means such as air cylinders or motors for simultaneous or individual adjustment of the rulers in height. Said vertical guide is supported on a pillar on which the sleeve holder is adjustable in height and movably mounted for reciprocating movement in the vertical direction by means of a drive means, such as an air cylinder. The sleeve holder is for this purpose supported on a support arm which extends horizontally from the pillar above the set of rulers and in the longitudinal direction thereof, more specifically in such a way that the center of the sleeve holder is directed towards the opening for the plant formed between the rulers in their horizontal position.
    The entire assembly comprising pillars, sleeve holder / sleeve holder head and its support arm as well as plant straighteners with rulers and associated storage and drive units are preferably jointly stored in the frame so as to be brought into position as a unit relative to the cassette and relative to the row of plants. The unit and / or the cassette can then be arranged to be moved stepwise relative to each other by a distance corresponding to the distance between the rows of plants. The sleeve holder is a tubular element which is arranged to releasably hold a sleeve and bring it into the movement of the sleeve holder for threading the sleeve onto the plant. The sleeve holder's grip on the sleeve may comprise a friction fit between the sleeve and the sleeve holder. A releasable engagement can alternatively be provided by means of a latch movably arranged at the sleeve, such as a heel or a shoulder, which entrains the sleeve in the movement of the sleeve holder and is then released to release its engagement with the sleeve. A third alternative may comprise an opening arranged in the wall of the sleeve holder to which a negative pressure is fed in order to hold the sleeve by vacuum during threading.
    The sleeve holder is included in a sleeve holder head to which sleeves are fed from a storage unit for individual fitting in the sleeve holder. Sleeve holder head with sleeve holder is supported in the support arm movably supported on the column and is carried in its movement when threading sleeves and back to the initial position above the plants.
    Basically, the fixation of the sleeve on the plant is met by the engagement of the sleeve with the green parts of the plant, ie. twigs and leaves or needles. If necessary, the sleeve holder head may comprise special means for fixing the sleeve to the plant, such as means by which a constriction can be formed in the upper end of the sleeve, for example by upsetting, riveting, stapling, gluing, etc. In one embodiment the upper end of the sleeve extends out of the sleeve holder. In the region of the protruding end, a stapler and an associated abutment are arranged in the sleeve holder head, which are driven in synchronous movement via a link system and for example an air cylinder for application of a staple through the upper part of the sleeve thereby creating a constriction which secures the sleeve to the plant. In an alternative embodiment, the sleeve holder head comprises a means designed to create a constriction in the upper end of the sleeve by upsetting.
    BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail below with reference to the accompanying drawings, in which an exemplary embodiment of the device according to the invention is shown. In the schematic drawings: Fig. 1 shows a perspective view of the device; Figs. 2a-2d show a set of rulers and sleeve holders included in the device, shown in end view and at different stages of a work cycle; Fig. 3 is a schematic top view of the rulers in the supporting position according to Fig. 2b, and Fig. 4 shows a partially sectioned view of a sleeve holder head included in the device.
    DETAILED DESCRIPTION OF AN EMBODIMENT It should be emphasized at the outset that expressions such as vertical or vertical or horizontal or horizontal in the description are used herein to describe the relationship between elements, planes or directions in the device, and should not be construed as an exact indication of these elements. the extent or orientation of planes or directions in space. For a detailed description of sleeves suitable for application to a plant plant by means of the present invention, reference is made to the initially mentioned WO 2007/133159.
    A device according to the invention comprises a stand 1 with a horizontally oriented receiving position 2 for a cultivation cassette (not shown), and a unit 3 movably stored in the frame 1 which is arranged for threading tubular sleeves over plant plants rising from cultivation cells included in the cassette. The assembly 3 mainly consists of a plant straightener 4 and a sleeve holder head 5 with a sleeve holder 6, which are movably arranged in the assembly and drivable in synchronized movements for positioning and direction of plants and for threading sleeves, respectively. In the exemplary embodiment, the assembly 3 is stored in a horizontal guide 7 and assigned to a linear drive means 8 with which the assembly 3 can be inserted over the cassette from a starting position next to and above the cassette.
    The plant straightener 4 consists of one or two sets of elongate disc-shaped elements or rulers 9 which fold in pairs and parallel side by side with a space adapted to the distance between the rows of plants in the cassette.
    The rulers 9 are rotatably mounted in a storage unit 10 by means of pivot pins 1 1 which extend in the extension of the ruler in the region of one of them, i fi g. l upper, longitudinal edge. Opposite longitudinal edge of the ruler has a number of evenly distributed V-shaped recesses 12. In the storage unit 10 is arranged an air-driven rotary motor 13 which via a gear transmission 14 rotates the rulers 9 in mutually opposite directions of rotation, from that in Fig. 1 and Fig. 2a shows the vertical rest position to a horizontal position according to Fig. 2b in which the recesses 12 meet and form an all-defined opening 12 '(see Fig. 3) in which the plant is caught and directed towards the sleeve holder 6. The plant straightener 4 shown comprises three such sets rulers which are movably mounted on a pillar 15 for height adjustment and associated with an air cylinder 16 and a link system 17 with which the mutual vertical distances of the line sets are regulated synchronously with raising and lowering of the planer 4.
    Adjustment of the height of the rulers over the cassette, as well as selection of a suitable sleeve length, is suitably based on a measurement of the height of the plants, for example by means of a number of optical sensor means not shown arranged at different levels in a holder 18. Measurement of plant height can be done with of two sensors, one of which is arranged to read a plant height up to 150 mm, while a second sensor is arranged to read a plant height above 200 mm.
    Furthermore, on the column 15 a support arm 19 is movably mounted and can be raised and lowered by means of a drive means obscured in Fig. 1, such as an air cylinder, the position of which in the device is indicated by the arrow 20. The support arm 19 carries the sleeve holder head with the sleeve holder 6 vertical movements on the pillar.
    The operation of the device will now be explained with reference to Figs. 2a-2d, in which a working cycle is illustrated in schematic end views of the plant straightener 4 and the sleeve holder 6. The working cycle of the pneumatic embodiment illustrating the invention can be briefly described including the following steps: in over the cassette with its rulers on either side of a planting line 0 The rulers turn to horizontal position 0 The rulers are raised 0 The plant height is measured 0 The sleeve holder goes down 0 The rulers are disengaged from the pneumatic drive to be passively rotated by the sleeve holder 0 The rulers go down synchronously with sleeve 15 20 25 30 35 0 The sleeve is left on the plant 0 If necessary, fixing the sleeve on the plant by stapling, spraining or other fixing action 0 The sleeve holder goes up 0 The rulers are turned to a vertical position 0 The plant straightener with rulers goes out of the cassette 0 To move to the next plant row in Fig. 2a a position after starting the cycle in which plantr the icter from an initial position next to the cassette is inserted over the cassette so that the rulers 9 extend between the rows of plants. The plant straightener is in its lowest position, and the sleeve holder 6 in its uppermost position above the plants and opposite a dividing line between the rulers 9 arranged in pairs, which in this position have a substantially vertical extension.
    From the initial position in Fig. 2a, the plant rectifier 4 is raised to that in fi g. 2b illustrated the supporting position, in which the rulers 9 are simultaneously or previously rotated to a substantially horizontal stretch. At this moment, the plants are caught in the recesses 12 of the rulers and stretched in the direction of the sleeve holder 6 and positioned in its path of movement.
    Fig. 2c illustrates the sleeve holder during threading of a sleeve 21 in an initial stage of the threading movement in which the rulers 9 of the top pair are rotated back in the direction of their vertical stretch and out of the path of movement of the sleeve holder.
    Fig. 2d illustrates a final stage of the threading movement in which the sleeve holder is in its lowest position. All rulers 9 have now been rotated out of the path of movement of the sleeve holder and extend on either side of the sleeve holder. At the same time, the leveler's line sets have been returned to their lowest position.
    The work cycle ends with the sleeve holder leaving the sleeve and returning to the initial position above the plants, whereupon the unit with plant straightener and sleeve holder is returned to the initial position next to the cassette. The cassette or unit is then moved one row apart to start the next work cycle. Finally, it should be mentioned that the device of the exemplary embodiment comprises a stapling apparatus schematically described with reference to Fig. 3 for fixing the sleeve to the plant by means of a staple. For this purpose, a stapler 22 with a staple magazine is supported in the sleeve holder head. The stapler 22 is mounted in the sleeve holder head and driven by an air cylinder 23 for a stroke movement in the direction of an abutment 24, which is driven via a system of link arms 25, 26 by the same air cylinder 23 for simultaneous pivoting and stroke in the opposite direction around a pivot axis 27. The stapler 22 and the abutment 24 meet in the extended centerline of the sleeve holder for application of a staple which penetrates the sleeve on either side of the stem of the plant. The abutment can advantageously have an anvil with grooves designed to fold the legs of the staple outwards, and suitably has a recess formed between the support surfaces in which the stem is received so as not to be damaged in connection with the stapling.
    It is further understood that a supply of sleeves, not shown in more detail, is suitably connected to the sleeve holder head, which are fed piece by piece to the sleeve holder before each work cycle.
    Loading of sleeves in the sleeve holder can advantageously be arranged to take place with the aid of air-driven mechanics for separating and feeding individual sleeves from one of several sub-stores containing sleeves of different lengths. In particular, it can be foreseen that when the sleeve holder is raised to the initial position before the next work cycle, it is pushed up over a fed sleeve and grips it in order to be carried in the next actuating movement.
    The device can alternatively be arranged with a single sleeve holder head 5 which moves on the support arm 19, or together with the same, for application of sleeves to all plants in the row. Preferably, the arm 19 carries a number of sleeve holder heads with sleeve holders 6 corresponding to the number of plants in the row for simultaneous threading of sleeves on all in a row standing plants.
    POSSIBLE MODIFICATIONS OF THE EXAMPLE EXAMPLE Instead of the three pairs of rulers of the exemplary embodiment, a modified planar converter may contain a smaller or a larger number of rulers. A larger number of rulers can advantageously guide plants of different lengths into the path of movement of the sleeve holder.
    Preferably, the number of rulers is at least two pairs. It is further conceivable that the direction of the plants takes place only by rotation of the rulers and without any vertical separation movement between the pairs of rulers.
    The rotation of the rulers can be controlled by means of individual valves to take place in pairs in series, with the beginning of the lowest pair of rulers, instead of simultaneous rotation of all rulers to the supporting position. If necessary, the free ends of the rulers can be stored in guides to increase their directional stability. Furthermore, the receiving positions of the rulers for plants may have a different shape, such as semicircular or elliptical, instead of the above-mentioned U- or V-shape.
    The planter can also, if necessary, be equipped with means that fold away the plants from adjacent rows of plants when positioning the unit above the cassette. Such a member can extend next to the rulers and in their full length to expose the plant row in question and in this way also facilitate the sensors' reading of the plant length.
    Alternatively, the sleeve holder and the sleeve holder head can be separately movably supported in the stand and their movement driven and controlled independently of the planer. In such an embodiment, the sleeve holder head with sleeve holders can be arranged to move horizontally laterally for picking up sleeves, as well as vertically for applying the sleeves.
    The above are only examples of such possible modifications which fall within the spirit of the invention as it is expressed in the claims.
