AUTOMATIC TYING MACHINE FOR CROPS, BUNDLES, OR BUNDLED PRODUCTS

Abstract

The present invention relates to an automatic tying machine for automatically tying binding wires in order to fix crops in a farmhouse or tie bundles or bundled products during distribution. More specifically, the present invention relates to an automatic tying machine which can use binding wires of different thicknesses, in which after a binding wire is drawn into a slot of a whirling binding wire guide device, the binding wire does not slip off from the slot during rotation of a slewing gear to prevent malfunctioning of the automatic tying machine for crops, such that it is possible to accurately and quickly tie crops, bundles or bundled products. Due to these features, the automatic tying machine has remarkable effects that can improve the productivity of work of tying crops, bundles or bundled products and improve work convenience.

MODE FOR CARRYING OUT THE INVENTION

[0042] According to the present invention, there is provided an automatic tying machine, comprising a case having a front opening for inserting a crop, a bundle, or a bundled products, a tying string supply provided behind the case, a feeder providing a tying string of the tying string supply forward, a rotational tying string guide winding the tying string supplied from the feeder around the crop, bundle, or bundled product as a rotating gear is rotated by a driving motor, a tying string cutter cutting the tying string wound around the crop, bundle, or bundled product by the rotational tying string guide as the driving motor rotates reversely, and a tying string twister receiving a rotational force from the driving motor to twist both ends of the tying string cut by the tying string cutter, wherein the rotational tying string guide includes the rotating gear, the rotating gear including a guide structure which is an opening for positioning the crop, bundle, or bundled product inside the rotating gear, wherein a fastening slot and a rotating slot are formed on the rotating gear in a direction opposite to the guide structure, and wherein when the crop, bundle, or bundled product is positioned in the guide structure, the fastening slot and rotating slot of the rotating gear rotate around the crop, bundle, or bundled product while biting the tying string, thereby tying the crop, bundle, or bundled product.

[0043] The fastening slot is fastened onto the rotating gear and is spaced by a gap for receiving the tying string under the rotating slot. The rotating slot is formed on the rotating gear and over the fastening slot to pivot on a pivot shaft. The rotating slot includes a tying string guide support and a tying string compressing part to prevent the tying string from sliding off when the tying string is wound around the crop, bundle, or bundled product. A stopper is provided to control rotation of the rotating slot.

[0044] The rotating slot is rotated to fit the thickness of the tying string to thereby guide various thicknesses of tying strings. The rotating slot compresses the tying string by the tying string compressing part to prevent the tying string from sliding off.

[0045] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings to be easily practiced by one of ordinary skill in the art. However, the present invention may be implemented in other various forms and is not limited to the embodiments shown in the drawings.

[0046] According to the present invention, an automatic tying machine includes a case having a front opening for inserting a crop, a bundle, or a bundled products, a tying string supply provided behind the case, a feeder providing a tying string of the tying string supply forward, a rotational tying string guide winding the tying string supplied from the feeder around the crop, bundle, or bundled product as a rotating gear is rotated by a driving motor, a tying string cutter cutting the tying string wound around the crop, bundle, or bundled product by the rotational tying string guide as the driving motor rotates reversely, and a tying string twister receiving a rotational force from the driving motor to twist both ends of the tying string cut by the tying string cutter. The rotational tying string guide includes the rotating gear, the rotating gear including a guide structure which is an opening for positioning the crop, bundle, or bundled product inside the rotating gear. A fastening slot and a rotating slot are formed on the rotating gear in a direction opposite to the guide structure. When the crop, bundle, or bundled product is positioned in the guide structure, the fastening slot and rotating slot of the rotating gear rotate around the crop, bundle, or bundled product while biting the tying string, thereby tying the crop, bundle, or bundled product.

[0047] Referring to FIGS. 1 to 8, according to the present invention, an automatic tying machine includes a case 100 having a front opening for inserting a crop, a bundle, or a bundled products, a tying string supply 200 provided behind the case, a feeder 300 providing a tying string of the tying string supply forward, a rotational tying string guide 400 winding the tying string supplied from the feeder around the crop, bundle, or bundled product as a rotating gear is rotated by a driving motor, a tying string cutter 500 cutting the tying string wound around the crop, bundle, or bundled product by the rotational tying string guide as the driving motor rotates reversely, and a tying string twister 600 receiving a rotational force from the driving motor to twist both ends of the tying string cut by the tying string cutter. The rotational tying string guide 400 includes the rotating gear 420. The rotating gear 420 includes a guide structure 410 which is an opening for positioning the crop, bundle, or bundled product inside the rotating gear. A fastening slot 421 and a rotating slot 421 are formed on the rotating gear in a direction opposite to the guide structure.

[0048] In this case, the fastening slot 421 is fastened onto the rotating gear 420 and is spaced by a gap for receiving the tying string under the rotating slot 421. The rotating slot 421 is formed on the rotating gear 420 and over the fastening slot 421 to pivot on a pivot shaft 427. The rotating slot 421 includes a tying string guide support 424 and a tying string compressing part 425 to prevent the tying string from sliding off when the tying string is wound around the crop, bundle, or bundled product. A stopper 426 is provided to control rotation of the rotating slot 421.

[0049] The rotating slot 421 is rotated to fit the thickness of the tying string to thereby guide various thicknesses of tying strings. The rotating slot 421 compresses the tying string by the tying string compressing part 425 to prevent the tying string from sliding off.

[0050] That is, the tying string guiding support 424 supports the tying string to allow the tying string to rotate around the crop, bundle, or bundled product. The tying string compressing part 425 compresses the tying string to prevent the tying string from sliding off.

[0051] According to the present invention, with the configuration of the fixing slot 421 and the rotating slot 421, the automatic tying machine allows for use of various thicknesses of tying strings and may prevent the tying string pulled into the slot of the rotational tying string guider from sliding off the slot when the rotating gear rotates. Thus, the automatic tying machine may be prevented from malfunctioning while automatically tying crops, bundles, or bundled products in a quick and precise manner, thereby enhancing productivity and work convenience in tying crops, bundles, or bundled products.

[0052] The above-described embodiments are merely examples, and it will be appreciated by one of ordinary skill in the art various changes may be made thereto without departing from the scope of the present invention. Accordingly, the drawings are provided for illustrative purposes, but not to limit the scope of the present invention, and should be appreciated that the scope of the present invention is not limited by the drawings. The scope of the present invention should be construed by the following claims, and all technical spirits within equivalents thereof should be interpreted to belong to the scope of the present invention.
