    The present invention relates to the baling of [vegetable fibers.
    In particular, it relates to a cylindrical baler for the above materials which take the form of a vegetable layer or swath, involving, in particular, but not exclusively, {10 aligned flax fibers, Such machines, not- | are generally referred to as 9 yarn winding machines.
    This type of machine is generally located downstream of scalding lines,
    A known technique consists of wrapping the vegetable layer under pressure in the form of a cylindrical bale.
    To this end, the machine consists of:
    - an inlet for the vegetable lasg and a cylindrical bale former with a device for forming the cylindrical bale and an upper belt:
    a feeding device for feeding the vegetable layer of the inlet in the cylindrical bale former in a feeding direction, the feeding device comprising at least one feed belt around the vegetable
    Move low in the feed direction Le, which cylindrical bale former includes an upper belt and a cylindrical bale chamber which is at least partially bounded by the upper belt and the supply belt;
    It is known that in some balers the top belt and the feed belt rotate in the same trigonometric directional to wrap the layer on mich. It is also known that the top belt is designed to deform during bale formation to adapt to the larger diameter of the bale that is formed. It is further specified that the machine may comprise a single 9 supply belt, which is then in the form of a conveyor belt, or 9 multiple supply belts parallel to each other. | The same applies to the magic band and / o0Ë the band | downstream. 9 10 | Once formed, the cylindrical bale is usually tied with a 9 rope before being led out of the machine. 9 In practice, it sometimes happens that the vegetable layer 9 15 does not wrap properly or at all, which leads to a blockage. The operator must then stop the machine for an intervention to loosen the layer, greatly increasing the time required to bale the flax fibers.
    The object of the invention is to address the aforementioned drawbacks by providing a cylindrical baler that facilitates the formation of cylinodric traps.
    To this end, the cylindrical baler according to the invention further comprises a starting mechanism to initiate the formation of the cylindrical bale in the chamber, the starting mechanism comprising a push element movable between an upstream position and a downstream position, the push element being configured that it pushes the layer into the chamber to initiate the flattening of the vegetable layer in the core.
    It is clear that, by moving from the upstream to the downstream position, the push element: pushes the layer to the chamber below the first roller, which causes the | piant layer helps to get into the room, which it | 5 winding in motion. In other words, the {displacement of the duvelement avoids the | vegetable layer comes in contact with the top band before entering the room 9. This prevents blockage and | winding is promoted at the same time. 9 Advantageously, the push element can be rotated around one. : hinge axis that is perpendicular to the supply direction. This 3 pivot axis is mainly horizontal,: 15 The push element is hingedly mounted on the frame and 9 has a slanting movement. 9 The push element is preferably located at a first 9 end of at least one arm which is hinged around the frame in relation to the 9 20 frame. pivot shaft is mounted.
    The hinge connection between the arm and the frame is located}. Preferably a second end of the arm opposite the first end. Advantageously, the starting mechanism additionally comprises at least one actuator configured to move the duvel element in a hinged reciprocation about the hinge axis.
    Preferably, the actuator is a pneumatic jack. This pneumatic jack can be manually activated by the operator. According to a variant, the starting mechanism comprises a sensor for detecting the start of the take-up, and an operating element that controls the actuator to set the duvel element in motion. When the sensor is | has detected the beginning of cylindrical baling, the control element causes the push element to become; moves to its upstream position where the | remains during bale finalization,; The pushing element advantageously comprises at least one pin | 10 mounted on a support, with the pin located between the 9 supply conveyor and the upper conveyor when the duvelement | is in its downstream position: Preferably, the thickness of the pin is slightly less than the smallest distance between the upper belt and the supply belt.
    Preferably, the pushing element comprises a plurality of pins co-spaced from each other. Preferably, each pin has an end portion which is substantially parallel to the supply belt when the pushing element is in a downstream position. Thanks to this construction, the duvel element prevents the fibers of the chase from going backwards when the push element returns to its upstream position. To facilitate winding, the end portion has a pushing surface transverse to the feed belt, configured to support the vegetable lasg pushes into the room.
    Preferably, the pushing element has a length that is greater than half the width of the Loefband. Preferably, the length of the pushing element, viewed in a direction transverse to the direction of supply, is essentially equal to the width of the Loevoergedeslite. 9 3 Um to avoid damage to the upper belt, the machine 9 additionally includes a stop for the movement of the pushing element | to stop in downstream position, | Advantageously, the machine further comprises a 9 18 blocking element to maintain the push element in upstream position. It is important to be aware of it make sure that the pushing element remains in the retracted position 9 during bale formation after winding | has started. | 15 Advantageously, the upper belt is mounted on at least one serious rot and the pushing element aidan, in downstream position, is between the first roller and the supply belt. It goes without saying that in that case the first roi and the Loevedband define an inlet passage to the room, according to a variant, the bale former further comprises a drive cylinder between the first roll and the Loader belt, and the pushing element, in downstream position, is located between the drive cylinder and the feed belt. Preferably, the sanding cylinder is rotated in the opposite direction of the feed direction to participate in the bale wrapping.
    With the insight to make the invention clearer, an embodiment is described hereinafter by way of example, without any limiting character, with reference to the accompanying drawings, in which:
    - Figure 1 schematically represents the side of the cylindrical baler according to the invention, provided with a starting mechanism; 9 - figure 2 in more detail and in perspective a | 5 an embodiment of the pushing element of the starting mechanism (shown schematically in FIG. 1); | - figure 3 is a variant of the machine of figure 1 | wherein the upper belt and the supply belt form one piece 9 LG; and 9 - figures 4A and 4B show a variant of the machine from | Figure 2, in which a drive cylinder is arranged between the conveyor belt and the supply belt.
    Figure 1 schematically shows a cylindrical baler 10 for a vegetable layer N, generally called a yarn wrapping machine, which serves to form a cylindrical bale by wrapping a previously swung vegetable layer on itself, for example a layer of flax fiber, before tying it up and discharging along a rear part 12 of the machine 10.
    This machine 10 is primarily intended to be positioned downstream of a scallop line, known from 25 other documents and not shown here.
    The machine 10 has a frame 14 which is provided with an inlet 16 for receiving the vegetable layer N previously gathered by suitable already known means. As known from other documents, the machine 10 further comprises an outlet 15 around the cylindrical bales to drain.
    As illustrated in figure 1, the vegetable layer N enters the machine according to an infeed direction, also referred to as: "feed direction FP" encoded by means of a conveyor belt known from other {documents and not shown here, | In the present description, the terms | Considered «STFCOMOGWAaRts» and «downstream» in relation to the feed direction F,: 10 The machine 10 furthermore comprises a cylindrical bale former 18 9 which is arranged in the frame 14, This cylindrical # bale former comprises a forming chamber 19 for forming the 9 cylindrical bales in which the cylindrical bale B is formed.
    Since cylindrical bale formers already exist from other | As documents are known, we will limit ourselves here to a brief description of different variants, without any limiting nature, of the present invention.
    The machine 10 further comprises a feeding device 20 for feeding the vegetable layer N of the inlet 16 of the frame 14 into the chamber 19. The plant-like layer thus moves in the aforementioned direction of supply F. Here, the feeding device 20 comprises at least one supply belt 22, which forms a conveyor belt and serves to displace the vegetable layer N according to the feeding direction F.
    Seen in the feed direction F, it is noted that the feed belt 22 is mounted on an upstream roll 24 and there are rotating impellers 2e rotatable about rotational axes X1 for the upstream roll 24 and X2 for the downstream roll 26.
    The axes of rotation Xi and X2 are parallel to each other and essentially perpendicular to the direction of feed direction F.
    It is also clear that the vegetable layer becomes N; 5 carried by the top portion 22a of the supply belt 22, hereinafter referred to as "supply section 22a".
    In the schematic representation in Figure 1, the 9 supply belt 22 rotates clockwise, the vegetable layer N; 10 moves with the feed section 22a, from upstream to upstream, from left to right. The machine 10 comprises at least one top belt 30 mounted on at least a first roll 32 rotatable about the axis of rotation K3, parallel to the axis of rotation X2 of the roll downstream 26, In this example, the top belt 30 further comprises a first intermediate roll 34 which is rotatable about an axis of rotation X4 2Ù parallel to the axis of rotation X3 of the first roller 32, the first intermediate roller 34, in this example, being disposed upstream of the first roller 32, slightly above it, The upper belt 30 is further supported by a second intermediate roller 36 which does not rotate an axis of rotation X5, parallel to the rotational axis X4 of the first intermediate roller 34, in the example of figure 1, without any limiting character, the second intermediate roller 36 is arranged above the first roller 22 such that the upper belt 30 is an upstream part 38 shows that it is oriented mainly vertically.
    The direction of movement of the upper belt 30 is configured such that the upstream portion 3rd
    N BE2019 / 5423 2 moves from the second intermediate roll 36 to the serest roll 32. It is further apparent that the first roll 32 # is slightly above the feed portion 22a of the supply belt | 22 Lis raised slightly upstream of the axis of rotation X2 of the roll downstream. It is also assumed that the top belt passes under the first roll 32. The top belt 30 is further carried by other rollers 33 9 with which the top belt can be set in motion. | 10 3 As is clear from Figure 1, the upper belt 30 turns in | silly phrase. The machine 20 further includes a downstream belt 40 which is downstream of the upper belt 30: sprung and, in this example, slightly upstream | 15 of the rotation axis K2 of the roller downstream 26. 9 The belt downstream 40 is in turn driven # by multiple rollers and more specifically a portion of the Downstream 42 extending between a second roller 2Û44 rotatably mounted about a rotation axis X6 parallel to the axis of rotation X2 of the roller downstream 26 and a third roller 46 rotatably mounted about an axis of rotation X7 parallel to the axis of rotation X6 of the second roller 44. The belt downstream is driven clockwise. The third roll 46 is located above the second roll 44, so that the downstream portion 42 is oriented substantially vertically when starting cylindrical baling, the upstream portion moving from the second roll 44 to the third roll 46.
    In other words, the upstream portion 38 of the top belt 30 and the downstream portion 42 of the downstream belt 40 are opposite each other and extend almost vertically, at least during the bale start-up phase, while driving in the opposite direction. 9 5 Seen in the feed direction F, the second roll 9 is in turn downstream of the roll downstream 26 | and of the first roll 32. According to the invention, the machine further comprises a | 10 starting mechanism 50 to start cylindrical baling B | start, As is clear from figure 1, the 9 cylindrical bale B is formed in the chamber 19 by the | vegetable layer N according to winding the winding direction E in itself. In this example, without any limiting character, winding takes place between the upstream part 38 of the upper belt 30 and the downstream part 42 of the downstream belt 40, which are driven in opposite directions. direction, and above the Feeding portion 22a of the feeding belt 22, As explained above, the starting mechanism has the function of starting the cylindrical baling B, for this purpose it comprises a pushing element 52 which is rotatable about a hinge axis Y perpendicular to the feeding direction FP. In other words, in this example, the pivot axis Y is parallel to the axis of rotation XZ of the roll downstream Z6.
    Preferably, viewed in a horizontal direction and transverse to the supply belt, the pushing element has a length of 52% greater than half the width of the supply belt
    22. Preferably, the length DL of the pushing element is substantially equal to the width of the supply belt. | Furthermore, the pushing element 52 is movable relative to | 53 the box 14 between an upstream position, 9 illustrated by a dotted line in figure 1, and a position | downstream, illustrated in full line in figure 1. 9 The push element 52 exhibits a back and forth movement such that it exerts a pushing effect against the vegetable layer N 9 10, during the movement of the push element 9 from the upstream position to the downstream position. position, | to pass the layer under the first roll 32 of the upper belt 30 and contact the downstream portion to facilitate entry of the layer into the chamber and winding it up. when the front portion of the vegetable layer N comes into contact with the downstream portion 42 of the downstream belt 40, it is considered to be fed up through the upstream portion and tends to deflect until it contacts with the net section of the streamcow 38 of the top band 30 that brings the Layer back to the ridden.
    Thus, the end of the layer N comes into contact with a part of itself that continues to move to the downstream portion 42 of the belt downstream 40, thus causing the Layer to wind on itself in the winding direction E as illustrated in Figure 1 In this example, the push element 52 is located at the first ends 548, 5a4a; of two arms 54, 541 hingedly about the pre-clamped pivot axis Y located at the second ends 54b, 54bi of the arms, opposite the first ends 54a, 54a; is located.
    The star mechanical mechanism 50 further comprises at least one actuator 60, in this example a pneumatic jack, which is configured. hinged back and forth movement, such as | As can be seen from Figure 2, the duvel element 52 comprises several | pins 53 mounted on a support 55, The tips: 16 are parallel to each other and are spaced from each other to form a comb, The support 55 extends | from between the first end 54a of the first arm 54 and 9 the first end 54a; of the second arm 54 ", Each pin | 23 further exhibits an end portion 53a which is substantially isod right to the support 55.
    Each end section 53a is flat and substantially parallel to the Supply conveyor, and more specifically to the supply section 228 of the supply conveyor 22, when the duvel element is in a current-flow position, as illustrated in FIG.
    1. It is also understood that the end portion 53a extends between the first roll 32 and the feed site 22a of the feed belt 22 when the duvel element is in a straw downstream position. The end portion 52a has a pushing surface 53b which is transverse to the feed belt. This pushing pocket 53b serves to more easily push the vegetable layer under the first roll to the belt downstream. When we return to Figure 1, it is clear that the machine further includes a stop 70 to move the duveloment 52 into the downstream position. in other words, when the duvel element has reached the downstream position, with the end portion 53a located below the first roll 32, | the arm 54 rain the stop 70 holding the pushing element immobilizes,: € | The machine further includes a blocking element 80 to hold the pushing element 52 in an upstream position, # Figure 3 illustrates a cylindrical baler 10 ° dis 9 9 is a variant of the machine 10 of Figure 1. The machine 10 ° 9 also includes: 9 - a frame 14 'provided with an inlet 18 ”for the vegetable layer and a cylindrical bale former 18' provided with a mold chamber 187. To form the cylindrical bale:
    Zen feed device 20% for introducing the vegetable layer of the inlet 16 'of the frame 14' into the said cylindrical bale molding chamber 18 "according to a feeding direction F, the feed device Z0 'comprising at least one feeding belt 22" for displacing the vegetable layer N according to the feed direction.
    The chamber for forming the cylindrical bales is at least partially delimited by the top belt 30 ", the downstream belt 40" and the feed belt 22 °. The essential difference between the machines of [figures! and 3 lies in the fact that the upper belt and belt 20 flow 30, 40 ° of the machine 10 ° in figure 3 form one and the same belt.
    Furthermore, the headband 320 ”is mounted on at least a cerebral roller 32 ° located above the feed belt 227" k, the top belt having an upstream portion 387 | moving in a first direction. 9 The feed tooth is arranged below the top belt and extends Seen in accordance with said feeding directions, sisters roll upstream 24 'and roll downstream | 26', the feed belt having a feed section 22a '| 10 positioned below the upstream section 38 °, 9 the downstream conveyor 40 'is mounted on at least one 9 second roll 44', this second roll, viewed in the direction of feed direction F, is located in the room 9 downstream 26 and from the first roll 32 °, with the tape downstream a downstream portion 42 ° is opposite the upstream portion, with the downstream portion moving in a second direction, opposite to the first direction. In accordance with the invention, the machine 10 "further includes a 50 ° starting mechanism to start forming the cylindrical bale B.
    The starting mechanism is similar to the starting mechanism of Figure 1 and includes a 52 ° dueling element which is movable relative to the frame 14 ° between an upstream position and a downstream position.
    The duvel element 52 "is configured such that it pushes the wicked layer N and the first roll 32" to the downstream portion 42 "of the belt downstream 40 ° to wind up the vegetable layer between the
    N BE2019 / 5423 upstream section, start upstream section and feed section,
    {Figures 4A and 45 are a schematic representation of a | 3 another variant of the cylindrical baler 10 ° ", which {differs from the machine 10" from Figure 3 in that no | property is downstream and due to the fact that the top belt 9 20 ° "extends directly between the first roll 32 ° and the second roll | 4 'and in the opposite direction from the 9 i0 direction of the top belt 30' of the machine 10 ° from figure 9 3 is driven: To allow the layer to wind on itself, a drive cylinder 70 ° 'is provided, in this example a 9 star cylinder, which rotates in the same direction as # the first roll 32 ° ”to low back to the conveyor belt. In other words, in this variant, the first roll 32, the second roll 44 °, the roll downstream 265 and the drive cylinder 7077 rotate in the same trigonometric view.
    According to the invention - does the machine 107 comprise a starter mechanism 50 ° "comparable to the starter mechanism 50 of figure 2. The starter mechanism 50 °" thus also comprises a push element 52 ° "with which the winding of the bale B in the chamber can be started.
    In figure 4A the pushing element SE is in the downstream position, while in figure 4B the dueling element is 52 ° in the upstream position.
    The duvelement 52 "therefore has the consequence that the passage of the layer N between the drive cylinder 70 °" and the
    _ BE2019 / 5423 The supply belt 22 ° is forced so that it enters the chamber 19 ° ”where it is wound up.
