Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a root vegetable tying machine, and more particularly to a root vegetable tying machine capable of continuously tying root vegetables.

[Prior Art] In general, for the convenience of drying root vegetables such as radish in the sun for transportation or pickling after harvesting,
It is necessary to tie the stems and leaves in desired numbers with string. As for tying agricultural products without manual labor, tying machines for tying grain rods such as rice are widely known.

As shown in Fig. 11, this binding machine a is used mounted on a combine harvester or the like, and sequentially transports grain rods A in one direction B, binds them with strings C, and discharges them outside the machine. It's becoming like that. Its configuration includes a table b for placing the grain rods A, a packer c for transporting the grain rods A to a binding area D which is provided under the table b in a double-acting manner and is a binding position. A string holder d provided above the binding area D and having a blade for pinching one end of the string C and cutting the string C; and a string C provided close to the rear of the string holder d in the conveying direction B. a knotted beak e for tying, a needle f that is deployably provided below the table b and supplies the string C to the binding area D, and a needle f that protrudes forward in the traveling direction B of the binding area D and is below the table b. It consists of a T-protrusion g that is swingably provided above the string holder d, and a release arm h that is swingably provided above the string holder d and for releasing the tied grain rods A out of the machine.

The needle f is formed of an arc-shaped member i that slidably holds the other end of the string C at its tip, and an arm j that supports this. It is designed to be able to expand upwards. Further, the string holder d and the nodule beak e are each provided with gears at their upper ends, and a drive gear k that meshes with these is provided. This driving gear k rotates the string holder d and the knotted beak e intermittently around their respective axes, and the supplied string C.
It is designed for knotting, pinching, and cutting.

With this configuration, the grain rods A are sequentially conveyed on the table b to the bundling area D by the double action of the packer c whose tip traces a substantially elliptical trajectory. A string C is supplied to this binding region D in a substantially vertically traversal manner, and its end portion is held by a string holder d. Therefore, the front side of the grain rods A to be bundled in the transport direction B is surrounded by the string C and comes into contact with the T protrusion g. When a predetermined amount of grain rod A enters the binding area D, the needle f moves upward from the rear side of the grain rod A while paying out the string C, and the other end is folded back to the knot beak e and the string holder d. and hold it
It is formed into a loop shape to surround the grain rod A. At the same time, the front end of arm j pinches grain rod A between it and T protrusion g, compresses it, and gathers it into a density that can be bundled. After the knotting beak e knots near the top of the grain rod A, the string holder d cuts the other end side of the knotting position with a blade. The tied grain rods A are discharged to the outside of the machine by a discharge arm h. In this way, the grain rods are tied almost automatically.

If this binding machine a is applied as is to binding the stems and leaves of root vegetables, the stems and leaves are more fragile than the grain rods, so they will be cut by the pressure exerted by the patch c, the T protrusion g, and the arm j of the needle f, making it impossible to bind them. .

For this reason, the operator presses the stems and leaves with his hands and operates a binding machine that does not have a pressing action.
Proposal of a root vegetable binding machine for binding stems and leaves (Jikko Sho 57-
Publication No. 42264, etc.) have been made.

As shown in FIG. 12, this binding machine l is provided with an inclined plate o between horizontal receiving plates n having a height difference on a machine frame m, and a binding means p with a binding area D formed in the middle thereof. ing. No T-protrusion or packer is provided below the inclined plate o, and the arm r of the needle q is formed so as not to be pushed toward the binding area D. Further, a driving means s is provided between the machine frame m and the receiving plate n, and a clutch (not shown) is engaged/disconnected by an operation rod t provided above the tying machine 1 to release the needle. q, string holder d, and nodule beak e are started or stopped, respectively.

Therefore, the root vegetables E are slid down from the receiving plate n along the inclined plate o by the hands of the worker, and are moved to the binding area D.
Once this is reached, the operating rod is operated and the stems and leaves are tied together by the known action described above. Tied root vegetables E
falls onto the lower receiving plate n due to its own weight and is ejected from the machine. In this way, according to this binding machine 1, the stems and leaves are not pressed appropriately and are mechanically bound.

[Problems to be solved by the invention] By the way, in the above proposal, a series of steps are required to carry the root vegetables E into the binding area D, restrain the stems and leaves before stringing the string C, and start and stop the binding means P. This will be done as work. Therefore, these tasks have to be carried out by one person, which poses problems in that work efficiency is poor and the worker is likely to become fatigued.

Also, hold the roots with one hand and needle the stems and leaves.
The needle q is expanded upward while being supported by the string C in the binding area D supplied between the nodule beak e and the nodule beak e, which poses a safety problem for the operator.

Furthermore, the drive means s is constantly operated,
If there is an erroneous operation such as accidentally touching the operating rod t, the tying means p becomes idle, and the string C becomes wrapped around the knotted beak e and the string holder d, making it impossible to tie.
Damage may occur.

In view of the above-mentioned circumstances, the present invention was devised to provide a stem and leaf binding machine for root vegetables that is safe and improves efficiency.

[Means for Solving the Problems] The present invention provides a conveyor for transporting root vegetables by placing them transversely to the transport direction with the stems and leaves extending from one side, and a conveyor for transporting root vegetables in the middle of the conveyor. a binding means provided in the conveyor for supplying the leaves and foliage extended from the side of the conveyor so as to be conveyed across the binding cord from the conveying direction and folding back the same to the rear thereof to bind the leaves, and the conveyor; The stems and leaves of the root vegetables are moved parallel to the extended side part and in synchronization with the conveyor, and each desired number of root vegetables to be bound by the binding means is positioned at the rear of the conveyance direction, and is supplied from the binding means. A movable protrusion for aligning and pressing the stems and leaves against the binding string that crosses forward in the conveyance direction, and whether the root vegetables conveyed by the conveyor enter the binding area provided with the binding means. and a discriminating means for discriminating whether the binding means is the same and actuating the bundling means.

[Operation] The conveyor sequentially conveys the root vegetables with their stems and leaves extending toward the binding means. The binding means supplies the binding string into the binding area so as to cross the binding string from the front in the conveying direction. The movable protrusions press a desired number of stems and leaves against the string in the binding area to make them ready for binding. The determining means operates the binding means when the root vegetables enter the binding area, and does not operate the binding means when the root vegetables do not enter the binding area. The actuated binding means folds back the string to bind the root vegetables within the binding area.

Next, the operation of this embodiment will be explained in accordance with the procedure of the bundling work.

First, the drive source 35 is started, and the drive means 7 operates the conveyor 1, the movable protrusion 3, and the binding means 2. Then, a desired number of root vegetables E are placed on the rear side of the conveyor 1 in the conveyance direction B. At this time, the foliage part F is extended from the side part 12 of the conveyor 1 as appropriate so that, for example, a position about 150 mm from the so-called blue neck part of the root part G enters the binding area D. The movable protrusion 3 has a shape that partitions this stem and leaf part F. Moreover, the string C is supplied to the binding area D. The root vegetables E transported by the conveyor 1 are
A disc 2 forming a discriminating means 4 in front of the binding area D
Contact with 3. When the rotary arm 25 supporting the disk 23 is expanded upward, the wire 28 connects to the clutch portion 22.
, the locking shaft 44 is inserted into the engagement hole 49, and the first clutch arm 41 and the second clutch arm 45 are integrated.

As shown in FIG. 7, the movable protrusion 3
is pressed against the string C to surround the front thereof and to bind it so that it can be tied. Then, the cam 40 driven in synchronization with the movable projection 3 rotates the integrated arms 41 and 45 to pull the wire 47, so that the clutch of the binding means 2 is engaged. Now, as shown in FIG. 8, the needle 83 folds back the string C and wraps it around the binding beak 81 and the string holder 82. The binding beak 81 and the string holder 82 are knotted by a predetermined rotation and then cut to form a bundle of root vegetables E. The conveyor 1 carries this out to the front side in the conveyance direction B.

On the other hand, when the root vegetables E are not in the bundling area D at the start or end of work or due to a placement error, the disk 23 remains positioned downward, so the first wire 28 is locked. The shaft 44 is prevented from entering, and the arms 41 and 45 are disengaged. Therefore, even if the cam 40 rotates the first clutch arm 41 in synchronization with the moving projection 3 entering the binding area D, the binding means 2 will not operate.

In this way, the bundling work can be carried out continuously and reliably, improving work efficiency and ensuring the safety of the worker and the bundling means.

Further, the binding speed of the binding means 2 is, for example, 0.3
Since the conveyance speed is about seconds, which is much faster than the conveyance speed of the conveyor 1, there is no risk of failing to bundle the root vegetables E that have entered the binding area D. , it may be possible to make it possible to bind more reliably and to make it easier to place the root vegetables E. In this case, the clutch portion 22
An input shaft 38 equipped with a known intermittent drive mechanism, for example a cam 40, in a first gearbox 36 attached thereto.
It is sufficient to provide a gear with partially carved teeth, and adjust the gear so that the output side, which is transmitted to the conveyor 1, stops rotating for a predetermined period of time each time the gear rotates.

Furthermore, a protrusion similar to the moving protrusion 3 may be provided on the placement surface of the conveyor 1 to prevent the root vegetables E from rolling and to ensure more reliable conveyance. Although the conveyor 1 has been described as an endless belt in this embodiment, it may also be a rod conveyor.

In this embodiment, the disk 23 is provided as the root vegetable sensor 21, but it is also conceivable to provide a long slope 90 formed in a bridge shape as shown in FIGS. 9 and 10.

This long slope 90 is fixed to the end portion 24 of the rotary arm 25 and extends forward in the conveying direction to a predetermined length from the disk 23, so that a desired number of root vegetables E are placed on the long slope 90. , at least one is in the binding area D
, the rotary arm 25 is brought into contact with this, the wire 28 is moved, and the binding means 2 is operated.

With this configuration, the bundling work can be done more practically. That is, when only the disks 24 are configured, when placed at intervals as shown in the figure or when a bent root vegetable E is placed, it moves so as to fall between them, and the binding means There is a concern that the operation of 2 may be stopped. However, the long plate 90
By providing this, it is possible to prevent such bundling errors, reduce the labor required for mounting work, or relax restrictions on the shape of objects to be bound.

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) Conventional bundling machines require a single worker to carry out a series of tasks, but with a conveyor that conveys the root vegetables to the area of the bundling means, it is possible to perform a series of tasks by simply placing the root vegetables on the bundling device. By making it possible to tie the pieces together, it is possible to reduce the burden on the worker and improve efficiency.

(2) Conventionally, the bundling means was activated after the worker pressed the foliage by hand, but now a movable protrusion that synchronizes with the conveyor is provided, the foliage is pressed, and the binding means is activated by the discrimination means. Therefore, the worker does not need to be near the binding means, and work safety can be ensured.

(3) Since the determining means determines the presence or absence of root vegetables, it is possible to prevent the bundling means from being damaged due to idle operation due to erroneous operation.
