  Hereinafter, embodiments of the present invention will be described in detail for each example.

FIGS. 1-19 is a perspective view which shows the apparatus which knots the string-like body of Example 1. FIG. Each figure shows the state of each part of the apparatus during the process.
The apparatus shown in the figure has a function of automatically producing a ring provided with a knot for processing, for example, a string-like dried straw which is continuously supplied and tying kelp winding. The kelp roll is completed by inserting kelp later into the ring. This device can automatically make knots with good appearance on various string-like bodies as well as drought.

  The apparatus of FIG. 1 is configured to continuously supply the string-like body 12 from a supply apparatus (not shown). In this example, the guide bar 14 grips one end 13 of the string-like body 12 at its tip, and guides it to a place where the string end clamp 16 is located. Therefore, the guide rod 14 is configured to expand and contract in the direction of arrow A so that the tip thereof reaches the position of the string end clamp 16. Note that any of the mechanisms shown in the figure can be operated by, for example, air pressure or hydraulic pressure. Of course, it can also be electromagnetically operated by a solenoid.

  The tip of the guide rod 14 is processed into a bullet shape so that it can easily pass through a ring of the string-like body 12 described later. In addition, a clamp mechanism for grasping and releasing one end 13 of the string-like body 12 is incorporated in the notch at the tip of the guide rod 14. One end 13 of the string-like body 12 guided by the guide rod 14 is held by a string end clamp 16 so as not to move. The mechanism for guiding the one end 13 of the string-like body 12 to the string end clamp 16 may be a mechanism different from the guide rod 14. After the one end 13 of the cord-like body 12 is sandwiched between the cord end clamps 16, the binding core 24 rotates around the rotation shaft 25 as indicated by an arrow B and is disposed above the cord-like body 12.

  The string end clamp 16 rises from the state of FIG. 1 in the direction of arrow C, and holds one end 13 of the string-like body 12 in the state shown in FIG. That is, the string end clamp 16 functions to grasp the one end 13 of the string-like body 12 at two locations and then release it. Further, the one end 13 of the string-like body 12 is raised vertically by swinging about 90 degrees so that the one end 13 of the string-like body 12 can be easily delivered to the guide rod 14. Thereby, the string-like body 12 is made substantially horizontal and held with reverse tension. Accordingly, the one end 13 of the string-like body 12 is in a state of being raised through the bottom of the binding core 24.

  Next, as shown by the arrow D in FIG. 2, the first twisting arm 18 and the second twisting arm 20 move. That is, as shown in FIG. 3, the first twisting arm 18 and the second twisting arm 20 insert the arms under the string-like body 12. Thus, with the one end 13 of the string-like body 12 held, the first twisting arm 18 moves in the direction of arrow E as shown in FIG. 4, and the second twisting arm 20 is shown in FIG. And move in the direction of arrow F to operate the string-like body 12 so as to be slack. For this purpose, the first twisting arm 18 and the second twisting arm 20 have a mechanism that moves perpendicularly to the longitudinal direction of the string-like body 12.

  Although a stopper is provided to prevent the other portions of the string-like body 12 from lifting when the string-like body 12 is slackened, the illustration is omitted because it is too complicated. The function will be described with reference to FIG. Further, the first twisting arm 18 and the second twisting arm 20 operate so as to form a ring by twisting the slack. For this purpose, the first twisting arm 18 and the second twisting arm 20 have a mechanism for rotating the arm inserted below the string-like body 12.

  As shown in FIGS. 6, 7, and 8, the first twisting arm 18 grips the vicinity of the end 13 of the string-like body 12 at one place to loosen the string-like body 12, and The first ring 21 (FIG. 8) is formed by twisting in the direction. As shown in FIGS. 7, 8, and 9, the second twisting arm 20 grasps the string-like body 12 at a position farther from the first twisting arm 18 when viewed from one end of the string-like body 12. A slack is applied to the string-like body 12 and a twist is added to the slack to form a second ring 22.

  The first twisting arm 18 twists the slack by one and a half turns to form the first ring 21. Further, the second twisting arm 20 forms a second ring 22 by twisting the slack by one and a half turns in the opposite direction to the first twisting arm 18. Further, the first twisting arm 18 and the second twisting arm 20 are inserted through the first wheel 21 and the second wheel 22 through the linear guide rod 14 as shown in FIGS. Keep it in a state to let it go. As a result, the structure of the guide rod 14 is simplified, and the operation of the guide rod 14 can be performed only by linear movement in the direction of the arrow J.

  As shown in FIG. 10, the tip 15 of the guide rod 14 passes through the second wheel 22 and the first wheel 21 in order, and then grips one end 13 of the string-like body 12. Thereafter, the cord end clamp 16 swings in the arrow K direction to release the cord-like body 12. As shown in FIG. 11, the guide rod 14 grasps one end 13 of the string-like body 12 and moves in the direction of the arrow L to pass through the first wheel 21 and the second wheel 22 in order. .

  As shown in FIGS. 12 and 13, after one end 13 of the string-like body 12 passes through the first ring 21, the first twisting arm 18 swings in the direction of the arrow M, and the string-like body 12 is moved. Evacuate at the same time as releasing. As shown in FIGS. 13, 14, and 15, after one end 13 of the string 12 passes through the second ring 22, the second twisting arm 20 swings in the direction of arrow N, The body 12 is released and retracted at the same time. This completes the movement of the guide rod 14 in the direction of arrow L.

  In this series of movements, the binding core 24 receives a force in the direction of the guide rod 14 and moves in the direction of the arrow P. The binding core 24 supports the portion of the string-like body 12 that extends from the first ring 21 to the one end 3 of the string-like body 12. A knot is formed on the binding core 24 using the first ring 21 and the second ring 22. At that time, one end 13 of the string-like body 12 drawn in the direction of the guide bar 14 arrow L (FIG. 14) is partially cut off. At this time, the binding core 24 is configured to move in the direction of the arrow P in order to reduce the useless portion cut off as much as possible.

  Next, as shown in FIG. 15 and FIG. 16, the auxiliary hook 23 grips the string-like body 12 located between the first ring 21 and the second ring 22, passes the binding core 24, and ends the string end. It moves in the direction of the clamp 16 (the direction of the arrow Q). Then, as shown in FIG. 17, the first knot is formed by crossing the string-like bodies 12 on the side surface of the binding core 24.

  Further, as shown in FIG. 18, the guide bar 14 moves in the direction of the string end clamp 16 (direction of the arrow R) while holding the one end 13 of the string-like body 12, and on the side surface of the binding core 24, The string-like bodies 12 are crossed to form a second knot.

  FIG. 19 shows the loop of the string-like body 12 in a state where the knot 11 is completed and unnecessary portions are cut off. The figure shows a state where the ring 30 of the string-like body 12 is supported by the binding core 24. However, after that, for example, after the binding core 24 is rotated in the direction of the arrow S, the string-like ring 30 is automatically removed from the binding core 24 by a mechanism (not shown). In the case of a kelp roll, the kelp is inserted into the dried cocoon ring thus obtained to obtain a finished product. In addition, in the case of kelp winding, the shape of the knot 11 of the cypress ring greatly affects the commercial value. The apparatus described here can automatically finish the knot 11 of the ring 30 of the string-like body very uniformly. This is because the twist of the string-like body 12, the direction of the tension applied to the string-like body 12 when making a knot, and the like can be easily optimized depending on the position and amount of movement of the auxiliary hook 23 and the guide rod 14.

20, FIG. 21 and FIG. 22 are explanatory views showing the operation principle and the process of the apparatus of the present invention.
In the first embodiment, a specific apparatus, its configuration and operation are described. In this second embodiment, how the string-like body 12 is processed is explained by focusing on the shape change of the string-like body 12. To do. And the optimal processing method is also mentioned.

  First, (a) of FIG. 20 shows the supply process of the first string-like body 12. The string-like body 12 is supplied, for example, in a necessary length in order while being wound around the reel 32. One end 13 of the string-like body 12 is pulled in the direction of arrow A and advanced to the position of the string end clamp 16. At this time, the string-like body 12 may be supplied by an arbitrary mechanism. The string-like body 12 only needs to be held to such an extent that unintentional loosening or twisting does not occur, and a light back tension may be applied.

FIG. 20B shows a process in which the string end clamp 16 holds one end 13 of the string-like body 12.
In this method, the string-like body 12 is wound around the binding core 24 to form a knot. In a later step, since one end 13 of the string-like body 12 is taken up via the binding core 24, the cord end clamp 16 holds the one end 13 of the string-like body 12 in a position convenient for starting the take-up. I am doing so.

  (C) of FIG. 20 shows the preparation state immediately before performing the process which adds a slack to the string-like body 12. FIG. The first twist arm 18 and the second twist arm 20 are inserted below the string-like body 12. Further, when the first twisting arm 18 lifts the string-like body 12 in the direction of arrow E, the first stopper 27 is disposed so as not to be lifted up to both side portions.

  Similarly, when the second twisting arm 20 lifts the string-like body 12 in the direction of the arrow F, the second stopper 28 is disposed so as not to be lifted up to both sides. The first stopper 27 and the second stopper 28 are claw-shaped members that allow the string-like body 12 to move in the longitudinal direction and prevent the string-like body 12 from lifting. As described above, these are also provided in the apparatus of Example 1, but are not shown.

  20D and 20E show that the first twisting arm 18 and the second twisting arm 20 slack the string-like body 12, and the first ring 21 and the second ring 22 respectively. The state which forms is shown. For example, the first twisting arm 18 grips the vicinity of the one end 13 of the string-like body 12 at one place to make the string-like body 12 loose, and then the first twisting arm 18 is viewed from one end of the string-like body 12. At a position farther than 18, the second twisting arm 20 grips the string-like body 12 at one place and loosens the string-like body 12.

  Subsequently, the first twisting arm 18 twists the slack to form the first ring 21, and finally the second twisting arm 20 twists the slack to form the second ring 22. . In this order, the first wheel 21 and the second wheel 22 are formed. At this time, the string-like body 12 is fed out by a necessary amount little by little from the right side of the drawing. When the operations are performed in this order, an excessive force is not applied to the string-like body 12.

  FIG. 21A shows a step of grasping one end 13 of the string-like body 12 after the tip 15 of the guide rod 14 has passed through the second wheel 22 and the first wheel 21 in order. As shown in this figure, the positions of the one end 13 of the string-like body 12, the first wheel 21 and the second wheel 22 are positioned on substantially the same straight line. As a result, the guide rod 14 can be moved linearly in the direction of the arrow J, so that it can pass through the second wheel 22 and the first wheel 21 at a stretch and grasp the one end 13 of the string-like body 12.

  21 (b) to 21 (d), the guide rod 14 grips one end 13 of the string-like body 12 released by the string end clamp 16, and the inside of the first ring 21 and the second ring 22 in order. The process of passing is shown. At this time, the binding core 24 is supported so as to wind the portion of the string-like body 12 from the first ring 21 to the one end 3 of the string-like body 12.

  In this step, the binding core 24 is moved in the direction of the first wheel 21 with the tension generated by the movement of the one end 13 of the string-like body 12. That is, the binding core 24 is supported by the binding core movable support portion 26 so as to be movable in the P direction. The binding core movable support portion 26 applies a force to the binding core 24 by an elastic force with a spring or the like in a direction opposite to the arrow P. When the one end 13 of the string-like body 12 moves, the binding core movable support portion 26 follows the movement of the one end 13 of the string-like body 12 and moves the binding core 24 in the direction of the first wheel 21.

  As already described, when the binding core 24 is brought close to the first wheel 21 by the binding core movable support portion 26 in this way, the end material to be cut off at the one end 13 of the string-like body 12 after the binding is completed can be minimized. At the same time, excessive tension is not applied to the string-like body 12, and the shapes of the first wheel 21 and the second wheel 22 can be appropriately maintained. In the state of FIG. 21C, the first stopper 27 releases the string-like body 12 and retracts. Thereby, the 1st ring | wheel 21 approaches the binding core 24 and can prepare for the next knot formation process.

  22 (a) and 22 (b), the auxiliary hook 23 grabs the string-like body 12 located between the first ring 21 and the second ring 22 and moves toward the string end clamp 16, A process of forming the first knot by crossing the string-like bodies 12 on the side surface of the binding core 24 is shown. Immediately before the state (a) is reached, the side close to the binding core 24 of the pair of second stoppers 28 releases the string-like body 12, and the auxiliary hook 23 is inserted under the string-like body 12 that has been lifted.

  Thereafter, if the auxiliary hook 23 moves in the arrow Q direction with the guide rod 14 holding the one end 13 of the string-like body 12, the first knot 33 of the string-like body 12 is formed on the binding core 24. It is formed. The hardness of the knot 33 can be adjusted by the amount of movement of the auxiliary hook 23.

  It is not necessary to further supply the string-like body 12 after the step (e) in FIG. Therefore, for example, the second stopper 28 may be pressed so as not to move the string-like body 12 until the step (d) in FIG. 22 after the step (e) in FIG.

  The figure (c) shows that the guide rod 14 moves in the direction of the string end clamp 16 while holding the one end 13 of the string-like body 12, and crosses the string-like body 12 on the side surface of the binding core 24. The process of forming the knot 34 is shown. When the guide bar 14 is moved in the direction of arrow R by pressing the supply side of the string-like body 12 with the second stopper 28, the second knot 34 can be formed with an appropriate tension. In the above process, in order to make the two knots 33 and 34 on the string-like body 12, from the process of FIG. 21A to the process of FIG. No. Thus, productivity can be remarkably improved by eliminating the operation of changing the string-like body 12. Moreover, the control can be simple and speeded up.

  In the above method, the first knot 33 is formed in advance using the auxiliary hook 23, and then the guide rod 14 is moved to form the second knot 34. Thereby, when the string-like body 24 having a slightly flat cross section is bound, a knot having a good shape as required by kelp winding can be formed. However, when binding a string-like body having a round cross section, there is no problem even if the first knot 33 and the second knot 34 are formed at a stretch.

  That is, the guide bar 14 is moved from the state of FIG. 22A to the state of FIG. The auxiliary hook 23 becomes unnecessary. When the guide rod 14 moves in the direction of the string end clamp 16 while holding the one end 13 of the string-shaped body 12, the string-shaped body 12 is crossed on the side surface of the binding core 24, and the first one by the first ring 21 is obtained. The knot 33 and the second knot 34 by the second ring 22 can be formed simultaneously.

  The present invention has been developed to tie knots in dried straw for making kelp rolls, but can be widely used to tie knots in various string-like bodies. In particular, since the shape of the knot can be adjusted by optimizing the tension of the string-like body when forming the shape of the winding core and the knot, it is suitable as a production facility for products that place importance on the knot shape. Moreover, not only a string-like body having a circular cross section but also a polygonal cross section or a flat belt-like cross section can form a good knot.
