    A knotter for a baler.
    The present invention relates to a knotter for binding bales of harvested crop material or other substances, so that the bales can be processed, stored or manipulated in another way without breaking.
    In many cases, such bales are manufactured under high pressure conditions, so that the finished product is considerably denser than the loose material from which it is made.
    Although it can be generally explained that increased density in such bales is a highly desirable objective, the achievement of that goal was ennobled in many respects by the limitations of conventional wire or rope knots. Beyond a certain level of tension in the strands of wire or rope, the device encounters difficulties in holding the strands and manipulating them through the various movements associated with tying the opposite ends of the strands into a satisfactory knot or other type of connection. Moreover, the strands themselves can only withstand a certain level of tension before they will break.
    For balers making a single knot in each loop of rope that encircles a bale, one range in which considerable tension is created in the strands results from the procedure of pulling the strands between the closely abutting ends of a previous bale and the one formed to progressively elongate the material in the loop until the formed bale reaches its predetermined size, at which time the opposite ends of the loop are simply knotted together and the bale is thereby securely connected. The need to pull the strands between the adjacent bales in this way arises because each strand contains one end that is held by the knotting device while the rest of the strand is draped along the bale chamber. As the growing bale is pushed through the chamber, it pushes against the strand draped along the bale chamber and, since one end is anchored to the knotter, the strand must be pulled between the bales by the knotter to increase the length of the strand increase along that side of the bale next to the knotter. It is along this latter length that problems arise.
    To deal with these problems, balers were proposed in which each loop contains two knots. Two routes of rope subtracted from two separate feed rolls are knotted at the start of bale formation. As the size of the bale increases, more rope is subtracted from the feed rolls, but neither of the two routes of rope has to drag across the surface of the bale and the knot formed remains in the same place on the bale as its dimensions increase. At the end of a cycle to form a bale, two knots are formed in the two ropes, the first for the finished bale and the second for starting the next bale.
    A baler using such a knot device is described in US4142746, the drawings and description of which are taken over below as a background for the present invention, which relates to an improvement in one of the components of the knotter used in the baler of this patent.
    As will become apparent from the detailed description of US4142746 which follows, the knotter includes a rope holder that strongly grasps the two routes of rope to be knotted for the entire duration of the process of knotting the two desired knots. A device known as a "bill hook" rotates for the rope holder to form the knots and a cutter separates each knot as it is formed from the rope routes gripped by the holder. A rope finger placed under the bill hook is tilted to bring the routes of the rope within the reach of the bill hook at the start of the formation of each of the two knots.
    During the formation of the first of the two knots, i.e. the knot used to complete the loop wrapped around a bale, the rope is kept under tension by the compressed bale and this results in a dense knot with long ends protruding from the knot. Such a knot has no tendency to come loose during bale processing. While forming the second knot on the other side, the routes of the rope that is still gripped by the holders are only under the tension of the routes of the rope that is pulled from the feed rolls. These routes may include a spring arm for receiving of hanging rope and a friction device to prevent unraveling of the rollers, but the tension cannot be set too high based on the noise and the wear that the high tension would cause during baling. As a result, the second node is currently not as close as the first and has shorter ends sticking out. As a result, the second knot, i.e. the knot that connects the routes of rope together to form a new bale, runs the risk of coming loose while the bales are being processed.
    It is an object of the present invention to provide an answer to the foregoing disadvantages by producing a dense second long knot without increasing the force required to pull rope off the feed rolls.
    According to the present invention there is provided a knotter comprising a rope holder, a bill hook, an arm carrying a jaw and a cutting device and a rope finger operated by a drive mechanism to form two consecutive knots, the first to assemble two runs of rope tie that surrounds a finished bale and the second to tie together two runs of rope that are pulled from respective feed rolls to start the next bale, the rope holder serving to grab the two runs of rope pulled from the feed rolls during forming of the two knots, the bill hook serves to tie the runs of rope grabbed by the holder, the cutting device serves to cut the runs of rope between the holder and the bill hook, the beak pushes the runs of rope off the bill hook while completing each knot and the rope finger is tilted on the side of the bill hook that is opposite the rope holder around the parts of the lop and bringing the rope to be tied within the range of the bill hook, characterized in that an edge of the rope finger that contacts the running of rope when the knots are pushed away from the bill hook by the jaw contains an obstruction to resist the movement of the running of the rope in a direction transverse to their length.
    The obstruction can be a rounded protrusion on the side of the rope finger that preferably cuts the side from which it protrudes at an acute angle.
    Preferably, the side of the protrusion that makes contact with the running of the rope extends largely at right angles to the edge (118a) of the rope finger.
    When the bill hook turns to finish the formation of the second knot, the two loops of the rope drag along the side of the rope finger. By providing an obstruction on this side to obstruct the movement of the ropes, the invention allows the part of the routes of the rope containing the second knot to be under higher tension than the part of the routes of the rope rope that is pulled from the feed rolls and in this way obtains a superior knot without increasing the force needed to pull the rope off the two feed rolls.
    The invention will now be further described, by way of example, with reference to the accompanying drawings, in which:

    In the description that follows and in certain foregoing passages, the principles of the present invention will be described using the terms "rope" and "knots" formed in such rope. However, it must be acknowledged that such principles extend to thread and twisted connections of thread as well as rope and knots. The conclusions must be interpreted accordingly.
    The baler 20 shown in Figure 1 has a rectangular bale chamber frame 22 that is supported for movement over the ground by one or more wheels 24. The bale chamber frame 22 defines a bale chamber 26 fed by a curved channel 28 which enters the frame 22 along the bottom thereof. A plunger 30 moves back and forth in the bale chamber frame 22 to periodically squeeze new loads of material from the channel 28 backward into the chamber 26 in the direction of the arrow 32. When the bale reaches a predetermined size, a switch-on device 34 is pulled by a rod 36 connected to a suitable bale length sensor (not shown) to enable a coupling 38. This connects a knotter 40 and its needle 42 to a source of driving force from the drive chain 44 associated with the clutch 38 to start the knot operation.
    The needle 42 is mounted on the bale chamber frame 22 by means of a tipping point 46 and is swung back and forth through the bale chamber 26 by means of rod system 48 which is activated by the coupling 38. The needle 42 has a "home" or rest position completely below the bale chamber frame 22 as shown in Figure 1 and a "end stroke" position fully extended through the bale chamber frame 22 as shown, for example, in Figure 8. As perhaps most clearly shown in Figures 3 and 17 the top 50 of the needle 42 has an eyelet 52 defined therein by the opposite bracket arms 54 and 56 of the bracket-shaped tip 50 together with a pair of longitudinally-displaced, transversely extending rollers 58 and 60. It should be noted that the roller 58 is positioned inward of the outer end of the tip 50, while the roller 60 is positioned outwardly from the roller 58 more in the vicinity of such an end. Likewise, the roller 60 is positioned a short distance inward from the outer end of the tip 50 and both rollers 58 and 60 may be chamfered toward their center points to form reliable seats for the strands to be tied as will become apparent later.
    As will also become apparent, although structures 58 and 60 are shown in the form of rollers, they can actually be formed as stationary transverse structures such as transverse pins.
    It is currently suggested that reference be made to Figure 2 which depicts the kind of the binding loop that relates to the present invention. Through the current reference to this figure, it is believed that the details of the structure described below, and the operation explained below, will be most easily understood.
    For this purpose, it should be noted that the finished product manifests itself in the form of a complete loop 62 that will completely encircle the finished bale. The loop 62 is formed from two strands of binder material, i.e., one strand 64 along the top of the bale and a second strand 66 along the bottom of the bale and its two opposite ends. The strands 64 and 66 thus completely encircle the bale and are complementary to each other. Two nodes 68 and 70 occur in the loop 62 at those locations where the strands 64 and 66 lie substantially with their ends against each other.
    On the left side of the loop 62 there is an incomplete loop 62a that is forming. Note that the upper strand 64a has its origin in a feed source 72, while the lower strand 66a has its origin in a completely separate second feed source 74. At the particular point in the sequence chosen for the figure, the node 68a exists and the Approaching the length at which the needle 42 is ready to swing into operation and present the strands 64a and 66a to the knotter 40 to complete the second node 70a (not shown).
    With this brief explanation in mind, the details of the structure as shown primarily in Figures 3, 4, 5 and 6 can be described. The knotter 40 is identical in many respects to a "Deering" type of knoter available via P.D. Rasspe Sohne, West Germany. That is, the components of the knotter 40 that work together to form each of the bale nodes can be identical to those in a unit supplied by the Rasspe company. However, the means to operate such components to make a double knot must be different. According to the embodiment shown, these means comprise a substantially circular element 76 mounted on a drive shaft 78 for rotation with the latter through one complete revolution when the clutch 38 is engaged. The shaft 78 is supported by a forward-leaning frame 80 attached to the top of the bale chamber frame 22, and the frame 80 also supports the above-mentioned components for forming the knots due to the rotation of element 76.
    In summary, such components include a rotatable bill hook member 82 supported by the frame 80 for rotation about an oblique axis 84, a multi-disc holder 86 near the rear of the bill hook 82 for holding strands 64a and 66a in a position for engagement by the bill hook 82 during rotation of the latter, and means for releasing the connected strands from the holder 86 in the form of an arm 88 tilted relative to the frame 80 by means of a bolt 90. The lower end of the the arm 88 is designed as a fork defining a jaw 92 that opens away from the holder 86 under the bill hook 82. The jaw 92 carries a cutter 94 between the bill hook 82 and the holder 86 for cutting the strands 84a 66a due to the swinging movement of the arm 88 in the correct direction. Such a movement of the arm 88 to operate the cutter 94 also serves to bring the closest parts of the jaw 92 into contact with a knot formed on the bill hook 82 to push such a knot off the bill hook 82 .
    In order to transfer the driving force from the element 76 to the bill hook 82, the latter is provided with a gear wheel 96 arranged to engage a pair of toothed slats 98 and 100 arranged at different places on the circumference of the element 76. Similarly, the drive force transmitted to the disks of the holder 86 along a worm gear drive 102 and a beveled gear 104 positioned to sequentially engage a pair of tooth sections 106 and 108 arranged at different locations on the periphery of element 76. Drive force to arm 88 to swing around the tilting bolt 90 is obtained along a cam follower 110 at the upper end of the arm 88 past the tilting bolt 90 that is mounted inside a cam track 112 on the element 76. A pair of circumferential cam shoulders 114 and 16 are positioned in the track 112 to sequentially couple with the follower 110 to operate the latter.
    A finger 118, which is not per se new, is located under the bill hook 82 and the jaw 92 of the knotter 40 and is mounted on an upright tilting point 120 for a laterally swinging movement between a rest position shown in Figures 3 and 4 and an end stroke, laterally extended position slightly beyond that shown in Figure 5. A drive rod 122 coupled to one end with the finger 118 and at the opposite end with a crank 124 has the function of causing the swinging movement of the finger 118. The crank 124, in turn, is attached to a transversely extending shaft 126 which extends to a point behind the element 76 where it carries a second crank 128 as shown in Figure 6. The crank 128 is inclined upwardly by a coil spring 130 and carries a cam follower 132 on its outer end. The follower 132 is in a business coupling position with a double-sided cam 134 secured to the shaft 76 for rotation therewith, the cams 136 and 138 are circumferentially displaced in accordance with the desired timing ratio between the finger 118 and the knot forming components of the knotter 40.
    Also mounted on the shaft 78 with the cam 134 is a second cam 140 with a circumference range with a ridge 142 extending about 180 degrees from its circumference and a circumference range with a trough 144 over the remaining 180 degrees of its circumference. Such circumferential ranges 142 and 144 are provided for operating coupling against a cam roller 146 mounted on the extreme end of a rod 148 which is fixed at its inner end to a transverse axis 150. The rod 148 and thus the rod 150 is elastically polarized in one direction counterclockwise as shown in Figure 6 through a coil spring 152, and the shaft 150 extends back to the opposite side of element 76, parallel to the shafts 78 and 126 up to a point substantially in line with the front-rear alignment of the bill hook 82.
    At this location, the shaft 150 carries a fixedly connected rearwardly extending compensator device 154. The device 154 carries a pair of rollers 156 and 158 relative to each other at its rear end around which strand 64a is wound, as shown in Figure 3. A length of the strand 64a also forms an upward loop around another roller 160 disposed above the device 154 and carried by the knotter frame 80 adjacent the drive shaft 78.
    Also worth noting at this point is the fact that the strand 64a can be clamped on the basis of friction between a pair of opposed plates 162 and 164 (Figure 3) of a tensioning unit 166. The force with which the plates 162 and 164 can clamp the strand 64a by a wing nut 168 which acts against a spring 170 which in turn presses against a slidable plate 164. A tensioning unit similar to the unit 166 can also be provided for the strand 66a although such an additional unit is not shown.
    OPERATION
    The state of the partial loop 62a in Figure 2 and that of the knotter 40 and the needle 42 substantially correspond to the state shown in Figures 3, 4 and 7, with the exception that in Figure 2 the needle 42 is still in its home position is. At this time, the bale has reached its desired length and it is time to complete the loop around the bale and make the second knot in the loop. Note that the strand 64a extends along the top of the bale immediately below the beak 92 of the arm 88, but, at least for all effective purposes, does not make contact with the knotter 40.
    As shown in Figure 7, while the needle 42 swings up toward the knotter 40, it carries the strand 66a with it while it is pulled from source 74. Also note that because the strand 66a is wired through the eyelet 52 of the needle 42 a length of the strand 66a on the side of the needle on the side of the rope source is also carried upwards to the knotter 40, this extra length is hereinafter referred to as 66b.
    During the period that the needle 42 approaches the knotter 40, no additional length of the strand 64a is subtracted from the source 72. Even if the tip of the needle 42, and more particularly the roller 60, stretches the strand 64a as shown in Figure 8 and strands 64a and 66a together present to the knotter 40, no additional additional length of the strand 64a is pulled from the source 72 because the device 154 tilts up in a counterclockwise direction to provide free rope length necessary in the strand 64a to to catch the movement of the needle. When presenting the strands 64a and 66a, the needle 42 actually drapes the strands along the bill hook 82 and then into the ready slots of the holder 86, after which rotation of cooperating discs in the latter serves to firmly grasp the strands and release them. occur when the bill hook 82 starts its rotation as shown in Figure 9. Note that during the period that the strands are delivered along the bill hook 82 to the holder 86, the finger 118 is driven to swing inwards and at least the strand 66a as shown in Figures 8 and 9 for the purpose of seating them deep in the jaw 92 to ensure that the strands 64a and 66a are both in the correct position along the bill hook 82.
    The foregoing movements on behalf of the bill hook 82 and the holder 86 are of course caused by operating coupling of the toothed bar 98 and tooth section 106 on the element 76 with their respective gears 96 and 104 on the bill hook 82 and the holder 86. A such a drive coupling remains until a knot has been formed on the bill hook 82 as shown in Figures 10 and 11, as soon as the needle 42 has started to retract. At this point, the cam shoulder 114 of the element 76 comes into contact with the roller 110 of the arm 88 to swing the underside of the latter, and thus the cutter 94, along this part of the strands between the bill hook 82 and the holder 86 cutting it as shown in Figure 11. Such a movement of the arm 88 also irons the finished knot 70a from the bill hook 82 and drops the finished loop onto the bale as shown in Figure 12.
    While the knotter 40 drops the knot 70a after cutting and wiping off the bill hook 82, the strand 66b to source 74, as well as the strand 64b to source 72 is held by the holder 86. Consequently, when the needle 42 continues to retract the strand 66b is draped down along the bale chamber 26 while the compensator 154 drops to its normal position to pull a small amount of additional material from the source 72. Upon reaching the state shown in Figure 13, the strands 64b and 66b are in a position for forming the second knot cycle which is started by swinging the finger 118 (previously returned to its rest position) inwardly about the strands 64b and 66b and seated deep within the jaw 92 as shown in Figure 14. This ensures that the strands 64b and 66b are correctly positioned along and in contact with the bill hook 82, whereafter the latter and the container 86 are operated by their second respective toothed bar 100 and toothed section 108 on the element 76. As a result, the knot is formed as shown in Figure 15, whereafter the arm 88 is once again activated, but this time through the second cam shoulder 116 around the button of the holder 86 to cut it off the bill hook 82. This becomes node 68b in Figure 16 and it is clear that such a connection of the strands 64b and 66a is the start of a new loop which, although not shown, would get the reference 62b. Such a new loop, upon its application, takes the form of a bend with an open end along the lines of, but much shorter than, the incomplete loop 62a in Figure 2. Such a bend is in position to receive new material that is pressed into the bale chamber by the plunger 30 and the bend grows in length as additional length of the strands 64b and 66b is simultaneously pulled from their sources 72 and 74. Finally, the sequence returns to its starting point when the bale has reached its desired size, after which the bend is closed by operating the needle 42 to complete the loop around the bale and forming the second node.
    As shown in Figure 2 and as also shown in Figure 16, two short segments 62 'and 64' are released by the holder 86 after the completion of the node sequence and in preparation for the start of the next sequence. Such segments remain as the result of the surplus of the strands held within the disks of the holder 86 after the two cutting layers of the cutter 94.
    It should be apparent from the foregoing that two complete knot cycles are performed during each single revolution of the drive shaft 78. Thus, every time the needle 42 swings in operation, two knots are formed by the knotter 40. one knot is the second knot 70 on the previous bale and the other is the first node 68 on the next bale. The cutting device 94 functions to cut the two nodes apart, thereby also separating the two bales.
    Of essential importance is that once the strand 66 is pulled along the bale chamber 26 when the needle 42 is pulled back and the knot 68 is formed, the strands 64 and 66 remain largely stationary relative to the bale formed during the remainder of the bale formation and knot forming process. The additional lengths of binder material necessary to accommodate the growth of the forming bale are easily obtained from the two separate feed sources 72 and 74, the resistance that pulls on such strands is only those exerted by the sources 72, 74 themselves and by any other units that control the tension that can be used, such as, for example, unit 166 in Figure 3. There is no need to pull any strand through the interface formed between the closely adjacent preceding bale and the one being formed, and thus it is avoided that the strands as well as the knotter 40 are subject to excessive stresses or loads.
    The description of the knotter as elaborated above is largely the same as that in US4142746 and the drawings are all largely the same except for the modification of the rope finger 118 shown in Figure 4. A complete description of the prior art was given so that a ! reader who is not yet familiar with the construction and operation of a double knotter can understand the function of the rope finger whose shape has been modified according to the present invention to improve the quality of the second knot as produced in the steps shown in Figures 13 up to 16 of the corresponding i figures.
    According to the present invention, the rope finger side 118a in contact with the course of ropes 64b, 66b when the second node of the bill hook 82 is pushed through the jaw 92 has a bump 118b that blocks the course of the rope as it attempt to slide along the side 118a under the action of the mouth 92. The side of the hump 118b that makes contact with the course of the ropes makes a right angle with the side 118a. The angle between the hump 118b and the side 118a captures the course of the ropes, but does not run the risk of cutting them. As a result of the obstruction 118b, the tension in the part of the course of the ropes between the finger 118 and the bill hook 82 is increased when the jaw 92 is tilted about the axis 90 to release the knot from the bill hook 82 on the same moment as the free end n of the rope is pulled through the bill hook 82 through the loop of rope wrapped around it, thereby tightening the knot and extending the ends protruding from the knot. This increase in tension is achieved without an increase in tension in the parts of the course of the rope pulled from the feed rolls.
