DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a scraper packer, a door for sensing a focusing pressure, and a needle for supplying a string on one side of a focusing space, and a knot building and a string holder on the other side. An opening for needle entry is formed in the string guide plate installed in front of the knot building and the string holder, and a string guide tool for receiving and supporting the tie string in the stem culm collection is provided at an intermediate portion of the opening. The present invention relates to a stalk-culm binding device.

[0002]

2. Description of the Related Art A bundling operation of a stalk-culm bundling apparatus as described above will be described. First, a tie string pulled out from a lace take-out port is used for a predetermined string receiving portion of a needle or a string guide of a string guide plate. The end portion of the strap is stretched so as to pass through the focusing space by being clamped and held by the strap holder at the back of the string guide plate. The stem culm is focused on the focusing space in such a manner that the stem stalk hangs over the stem culm receiving portion extending from the string guide member of the string guide plate. When a predetermined amount of stem culm is focused in the focusing space, a focusing pressure sensing door senses a focusing pressure higher than a set pressure, and with the sensing, a needle is wound around the stem culm where the needle is focused. The needle side portion of the tying string is supplied to the string holder by entering the opening of the guide plate. At this time, the string guide plate side in the needle side portion of the binding string is received and supported by a predetermined string receiving portion of the string guide tool of the string guide plate together with the string guide plate side in the string holder side portion. On the other hand, the knot building and the string holder start rotating in association with the operation of supplying the string of the needle, and with the rotation of the knot building, the string holder side portion and the needle side portion of the bundling string are wound around the holding claws of the knot building. At the same time, with the rotation of the string holder, the needle-side portion of the tying string is pulled into the string holder side by the hook of the lace holder, and is gathered into the string holder-side portion of the tying string. And, as the rotation of the knot building progresses, the string holder side portion and the needle side portion of the tying string
The knot building side passes over the tip of the string guide and is wound up by the holding claws of the knot building, and the string holder side assembled by the string holder is held by the holding claws of the knot building. Also, as the rotation of the string holder progresses, the action of the hooking claw causes the strap holder side portion of the binding strap held and held by the strap holder to be separated from the strap holder, and the needle side portion of the strapping strap to be tightened by the strap holder. And the knot building side of the needle side portion of the tying string newly held by the string holder is cut by the knife of the string holder. On the other hand, when the needle comes out of the opening of the string guide plate and returns to the initial position, a new binding string is stretched so as to pass through the focusing space, and the release arm is operated to be bound by the binding string. Extruded stems and stems. At this time, the stem culm side of the tying string that tied the stem culm with the extrusion of the stem culm moves together with the stem culm, and as this movement progresses, the string part wrapped around the claws of the knot building remains annular. When the cord is pulled out, the cord portion clamped by the claws of the knot building is externally clamped, so that a knot is formed and one bundling is completed.

[0003] Conventionally, in a stem-and-stem bundling apparatus which performs the above-described bundling operation, for example, Japanese Utility Model No. 7-288
As disclosed in Japanese Patent Publication No. 22-222, measures to prevent the binding strap received and supported by the strap guide from being displaced from a predetermined strap receiving portion of the strap guide to the root side of the strap guide are Had not been taken.

[0004]

Therefore, in the stem-and-culm bundling apparatus based on the above-mentioned prior art, when the bundled stem-and-culm is inclined in the outward falling direction, the tying string is operated by the needle. Due to the phenomenon that the tying string is wrapped around the shortest length when it is wound around the bundled stem, the stalk receiving part of the tying string (the part where the stem that moves to the focusing space becomes hung) It moves to the lower side (the root side of the string guide) of the bundled stem,
Along with this, at the time of stem stalk bundling, the string portion received and supported at the predetermined string receiving portion of the string guide is displaced toward the root of the string guide. As a result, when the knot building is rotated after supplying the needle-side portion of the tying string to the string holder by the operation of the needle, the cord holder-side portion and the needle-side portion of the tying string are wound around the claws of the knot building. The string portion received and supported at the predetermined string receiving portion of the string guide so as to be the winding start end is located near or outside the rotation locus of the holding claw, and the knot building is clamped. Since it becomes impossible to wind up the string holder side portion and the needle side portion of the tying string with the nail, a tying error has occurred.

[0005] An object of the present invention is to provide a simple improvement to a string guide so that a string portion received and supported at a predetermined string receiving portion of the string guide is displaced toward the base of the string guide. The object of the present invention is to prevent the occurrence of a binding error caused by the above.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, a scraper packer, a door for sensing a focusing pressure, and a cord supply are provided on one side of a focusing space. And a knot building and a string holder are provided on the other side, and an opening for needle entry is formed in the string guide plate installed in front of the knot building and the string holder. In a stem-and-culm bundling device provided with a string guide for receiving and supporting a tying string in a stalk-culm bundle at a site, the tying string is displaced toward the root side of the string guide at a string receiving portion of the string guide. A step portion for preventing the engagement is formed.

According to the first aspect of the present invention, in a case where the bundled stems and stems are inclined in the outward falling direction, when the binding cord is wound around the bundled stems and stems by the operation of the needle, Due to the fact that the tying cord is about to be wound with the shortest length, even if the stem culm receiving part of the tying cord moves to the lower side of the bundled stalk culm (the base side of the string guide), the tying culm is collected at the time of stalk culm gathering. The string portion received and supported at the predetermined string receiving portion of the guide is prevented from being displaced to the root side of the string guide by engagement with the step formed at the string receiving portion of the string guide. Become so.

In other words, when the knot building is rotated by supplying the needle-side portion of the tying string to the string holder by the operation of the needle, the string holder-side portion and the needle-side portion of the tying string are wound around the claws of the knot building. The string portion received and supported at a predetermined string receiving portion of the string guide so as to be the winding start end is displaced to the root side of the string guide and close to the outside of the rotation locus of the holding claw or rotated It can be prevented from being located at a position deviating from the trajectory, and as a result, even in a case where the bundled stems are inclined in the outward falling direction, the rotation of the knot building causes the tying string to be closer to the string holder side. Since the portion and the needle side portion can be securely wound around the holding claws of the knot building, the bundled stems can be securely bound with the binding string.

[0009] Therefore, by making a simple improvement in the string receiving portion of the string guide at the step of preventing the binding strap from being displaced toward the base of the string guide, it is possible to provide a simple improvement. It is possible to prevent the occurrence of a binding error caused by the displacement of the string portion received and supported at the predetermined string receiving portion in the above to the root side of the string guide.

According to the second aspect of the present invention,
The invention according to claim 1, wherein a concave portion is provided on the side of the string guide that faces the knot building and the string holder, the concave portion being capable of engaging and holding the binding string at the string receiving portion.
An end wall of the concave portion located on the root side of the string guide was defined as the step portion.

According to the second aspect of the present invention, when the bundled stems and stems are inclined in the outward falling direction, when the binding cord is wound around the bundled stems and stems by the operation of the needle, Due to the fact that the tying cord is about to be wound with the shortest length, even if the stem culm receiving part of the tying cord moves to the lower side of the bundled stalk culm (the base side of the string guide), the tying culm is collected at the time of stalk culm gathering. The string portion received and supported at the predetermined string receiving portion of the guide device is engaged and held by the string receiving portion at the concave portion provided on the opposing surface side of the knot building and the string holder of the string guide device. Thus, displacement of the string guide to the base side is prevented. Further, in the case where the bundled stems and stems are inclined in the inward falling direction, when the straps are wound around the bundled stems and stems by the operation of the needle, the straps are likely to be wound with the shortest length. Due to the phenomenon, even when the stem culm receiving portion of the tying strap moves to the upper side of the bundled stem culm (the tip side of the string guide), it is received at the predetermined string receiving portion of the string guide at the time of stem culm bundling. The supported string portion is engaged and held at the string receiving portion by the concave portion provided on the opposing surface side of the knot building and the string holder in the string guide, so that the displacement of the string guide to the distal end side is reduced. You will be blocked.

In other words, when the knot building is rotated after the needle-side portion of the tying string is supplied to the string holder by the operation of the needle, the string holder-side portion and the needle-side portion of the tying string are wound around the claws of the knot building. The string portion received and supported at a predetermined string receiving portion of the string guide so as to be the winding start end is displaced to the root side of the string guide, or displaced to the tip side of the string guide. As a result, it is possible to prevent the pinching claw from being located near the outside of the rotation trajectory or at a position deviated from the rotation trajectory due to being detached from the string guide tool. Regardless of the posture of the bundled stems and stems, the bundled stems can be held at the predetermined string receiving portion of the string guide, which is the appropriate winding start position for the holding claws, so that the bundled stems and stems can be removed. Regardless of the inclination direction of the knot building, the rotation of the knot building enables the string holder side portion and the needle side portion of the tying string to be securely wound around the holding claws of the knot building. .

In addition, a concave portion for engaging and holding a string portion serving as a winding start end with a predetermined string receiving portion of the string guide is provided on the opposing surface of the knot building and the string holder of the string guide. When the engaged and held string portion is wound around the claws of the knot building facing the concave portion, the cord portion is pulled out of the concave portion along with the winding around the claws, and is engaged with the predetermined string receiving portion by the concave portion. Since the holding is released and the displacement to the tip side of the string guide accompanying the winding operation is allowed, when the string holder side part and the needle side part of the tying string are wound with the claws of the knot building Can smoothly move over the tip of the string guide in the string portion, and as a result, the bundled stems and stems can be securely bound by the binding string.

Therefore, by making a simple improvement on the opposing surfaces of the knot building and the string holder in the string guide, a concave portion capable of engaging and holding the tying string at the string receiving portion is provided. It is possible to prevent occurrence of a binding error caused by unexpected displacement of the cord portion received and supported at the cord receiving portion of the cord guide device toward the root side or the tip side.
