Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a root vegetable tying machine, and in particular, a machine for tying root vegetables, which is capable of tying root vegetables while storing the foliage between protrusions that move in synchronization with an endless conveyor. This invention relates to a root vegetable tying machine that binds the foliage that fits between the protrusions during transportation and then discharges the foliage onto a table continuous to the end of the forward path of the conveyor.

[Prior Art] In a conventional root vegetable tying machine, an operator immediately picks up a bundle of root vegetables from the end of an endless conveyor after tying, to prevent the bundle of root vegetables from falling on the ground.

However, the work of picking up items was hectic, resulting in workers getting tired or failing to pick up items. Therefore, as shown in FIGS. 6 and 7, the applicant installed a continuous table 8 at the end of the endless conveyor 11, discharged the bundles of root vegetables 7 onto this table 8, and temporarily kept them on standby for work. We have succeeded in solving the above-mentioned problems by developing a stem and leaf binding machine 1 for root vegetables that allows for extra margin.

[Problem to be solved by the invention] However, in the developed stem and leaf binding machine 1 for root vegetables, when a bundle of tied root vegetables 7 is discharged from the end of the endless conveyor 11 to the table 8, The vicinity of the bound portion of the stem and leaf portion 4 of the waiting root vegetable 7 is cut into a down cut shape by being pinched by the table 8 and the protrusion 9 when going around the reversing portion of the roller chain 12.

In this way, the root leaves 7 whose stems and leaves 4 near the binding part have been cut become unstable in their binding state, and fall off from the binding strings 5 when being transported to the next process, resulting in an unbound state, which prevents the processing work in the next process. Productivity decreases as it becomes impossible to do so. Further, the root vegetables 7 whose stems and leaves 4 have been cut cannot be re-bound, causing problems such as being unable to be commercialized.

The present invention was devised to solve these problems, and is a novel product that prevents the cutting of stems and leaves, improves the binding yield, and allows the next process to be carried out accurately and efficiently. The purpose of the present invention is to provide a stem and leaf binding machine for root vegetables.

[Means for Solving the Problems] In order to achieve the above object, the present invention aims to transport root vegetables while storing their stems and leaves between the protrusions that move in synchronization with an endless conveyor. In a root vegetable tying machine that binds the stems and leaves that fit within the space and then discharges them onto a table continuous to the end of the forward path of the conveyor, the protrusions are rotatably supported on the conveyor at a predetermined interval and the forward path ends. It consists of a protrusion main body and a leg part that are set to tilt in the opposite direction in the conveying direction at the reversing part on the terminal end side, and is provided in parallel with the conveying body and engages with the leg part of the protrusion during the outward movement. It is equipped with a guide body that holds and guides the protrusion main body in an upright state.

[Function] In the above configuration, during the forward stroke of the conveyance body, the legs of the protrusions engage with the guide members, so that the protrusion bodies are held in a protruding state and push the stems and leaves. Then, the stems and leaves are bundled on the way, and further pushed by the projection main body to reach the terminal end of the conveying body. When the bound stem and leaf portion reaches the reversing portion of the conveyance body from the terminal end, the leg portions and the guide body are disengaged, and the protrusion main body rotates while tilting in the opposite direction to the conveyance direction. Therefore, the vicinity of the binding part of the stem and leaf part avoids the town-cutting effect by the protrusion main body.
