Abstract

PURPOSE:To convey a crop as keeping it on a conveying route as well as to make both ends of the crop cuttable automatically by regulating a movement of the crop with a width regulating member and a small diametral regulating member. CONSTITUTION:A crop 10 is conveyed in a constant direction by a conveyor means 11, while a width regulating member 40 and a vertical regulating member 50 come into contact with the crop 10 as being displaced according to size and form of the crop 10, whereby movements in both width and vertical directions of the crop 10 are regulated, thus the crop 10 is kept on a constant conveying route. Then, the crop 10 passes through a setup position of a pair of cutters 32 in a turning state, thus both ends of the crop 10 are cut off. At this time, since the paired cutter 32 is displaced solidly with a contact-separation member 20 together with the width regulating member 40, a cutting quantity is kept constant irrespective of form and size of the crop 10.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a crop cutting device for simultaneously cutting both ends of crops such as onions.

[Conventional technology]

Some of the commonly sold crops, such as onions,
Some are used for cooking by cutting off both ends. Cutting of such crops is done either in the processing process before marketing, or by the purchaser after marketing, but conventionally all of this was done by hand.

[Problem II that the invention seeks to solve]

As mentioned above, it is very troublesome to manually cut crops, and in order to reduce costs, there is a strong desire for a device that automatically performs the cutting.

However, since the size and shape of the crops mentioned above are not constant,
It is difficult to always cut a certain amount of both ends of various crops with a single device, and the cutting work is still done by hand.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a crop cutting device that can automatically cut both ends of crops having different sizes and shapes by a substantially constant amount at all times.

Means for Solving Problem C] The present invention is an apparatus for cutting both ends of a crop at the same time, and includes a conveyance means for conveying the crop in a fixed direction while supporting the crop from below, and a conveyance means for conveying the crop in a fixed direction while supporting the crop from below. a pair of contacting/separating members provided on both sides of the conveyance path and configured to be able to approach and separate from each other; a biasing means for urging these contacting/separating members in a direction in which the contacting/separating members approach each other; and each contacting/separating member. It is provided on the member and is pressed against both sides of the crop during WI transport by the biasing force of the biasing means, thereby suppressing the movement of the crop in the width direction.
a width regulating member disposed above the conveyance path so as to be movable up and down, and biased downward, and regulating the vertical movement of the crop by contacting the upper surface of the crop being conveyed; and a cutter, which is installed on each contacting and separating member, is oriented substantially parallel to the direction in which the crop is conveyed, and is positioned downstream of the width ruler-j member, and cuts both ends of the crop that is being conveyed in a rotating state. and cutter driving means for rotationally driving this cutter (fil requirement 1).

Further, the width regulating member and the cutter provided on each of the contacting/separating members are installed to be movable relative to each other in the contacting/separating direction of the contacting/separating member, and actuating means for relatively moving the width, the W sub-member and the cutter is provided. It is more preferable (Claim 2).

Furthermore, each width regulating member has a pair of pinching members that sandwich the crop being transported from above and below, and the downstream end of at least one of the pinching members is rotatable around the upstream end in the crop conveyance direction. A more excellent effect can be obtained if the bracket is configured such that the downstream end of the bracket is biased in a direction toward the other pinching member (Claim 3).

[Function] First, according to the apparatus according to claim 1, the crop is conveyed in a fixed direction by the conveying means, and the width regulating member and the upper and lower layer side members are displaced according to the size and shape of the crop. By contacting the crop, movement of the crop in the width direction and in the vertical direction is suppressed, and the crop is held on a constant conveying rod. When the crop passes through the positions of the pair of rotating cutters, both ends of the crop are cut. At this time, since the cutter is displaced together with the @ layer side member and the contacting/separating member, the amount of cutting is kept constant regardless of the shape and size of the crop.

Furthermore, according to the second aspect of the apparatus, the amount of cutting of both ends of the crop by the cutter is changed by relatively moving the cutter and the width regulating member provided on each contacting/separating member using the actuating means.

Moreover, according to the apparatus according to claim 3, both ends of the crop are sent to the cutter while being sandwiched from above and below by the pinching members of the width regulating member.

Next, the process of cutting the crop 10 performed by the apparatus described above will be explained.

First, the conveyance sprocket 12 shown in FIG. 1 is rotationally driven by a drive motor (not shown), and the rotation is transmitted to the conveyance sprocket 13 via the chain 14.
Conveyance sprocket 7 coaxial with this conveyance sprocket 13
2 rotates. Furthermore, this rotation is transmitted to the sprocket 68 of the crop conveyance device via the chain 70, and the sprocket 66 and the front and rear rotating shafts 63, 64 of the device rotate, and the chain member 75 begins to move in the crop conveyance direction.

In this state, as shown in FIG.
By placing the crop 10 between them, the crop 10 is stably supported from below and conveyed as it is toward the crop cutting device.

On the other hand, in the crop cutting device, the cutter 32 is rotationally driven by the cutter drive motor 31, and the chain 14 is operated in accordance with the movement of the conveyance sprocket 12, whereby the crop conveyance member 16 is sequentially moved in the crop conveyance direction. are doing. As shown in FIG. 1, the crop conveying member 16 passes between the left and right supports of the crop conveying device so as to pass between the members 76 from below, so that the supports are not supported between the members 76 until then. The crop 1.degree. that was being held is scooped up from below by the front portion 182 of the crop conveying member 16, thereby passing the crop 10 from the tray member 76 to the crop conveying member 16.

The crop 1o scooped up by the crop conveying member 16 is conveyed in a predetermined conveying direction (to the left in FIG. 1) while being supported from below by the horizontal portion 181 of the crop conveying member 16. When the crop 1o hits the regulation plate 501 of the vertical regulation member 50, the vertical regulation member 50 is pushed up against its gravity, and conversely, the crop 1o is held down from above by the vertical restraint member 5o. Its vertical movement is regulated.

That is, the crop 1o is conveyed in a predetermined direction while being in contact with the lower surface of the regulation plate 501.

Further, when the crop 10 reaches the area where the width regulating member 40 is arranged and both ends of the crop 10 come into contact with the pair of sandwiching plates 42, the upper sandwiching plate 42 is moved by its gravity due to the passage of the crop 10. At the same time, the width regulating member 40 is pushed open to the left and right outside together with the detachable table 20 against the tensile force of the tension spring 28. Conversely, both ends of the crop 10 are sandwiched from above and below and from the left and right by the pair of pinching plates 42, thereby restricting movement of the crop 10 in the width direction. Due to the regulation of the width regulating member 40 and the regulation of the upper and lower 11 members 50, the crop 10 is conveyed toward the cutter 32 while being held on a fixed conveyance path.

On the other hand, since the double-strength vines 32 are each fixed on the contact/separation table 20, they move outward to the left and right by the same amount as the width regulating member 40 moves. In this state, when the crop 10 passes through the installation position of the double-sided ivy 32, the crop 10
Both ends of 0 are cut off, and the remaining center part is placed at a predetermined location (
transported in a basket, etc.).

As described above, in this device, by regulating the movement of the crop 10 with the width regulating member 40 and the vertical regulating member 50, the crop 10 is conveyed while being held on a fixed conveyance path, and both ends of the crop are cut. 32, the crop 10 can be cut automatically without manual work as in the past. Moreover, the cutter 32 is fixed on the approach/separation table 20 like the width regulating member 40, and is always displaced together with the width ruler IIj member 40. Even if the actuator 10 is pushed open by a certain amount, both ends of the actuator 10 will always be cut by a certain amount. That is, regardless of the shape, size, etc. of the crop 10,
A constant amount of cutting can always be ensured.

Furthermore, in this embodiment device, the left and right width regulating members 40 are mounted to be movable in the width direction with respect to the approach/separation table 20, and the width regulating members 40 are moved relative to the approach/separation base 20 by rotating the feed screw 34. The position of the cutter 32 and the width regulating member 4 can be changed by this change.
By appropriately changing the relative position with respect to 0, the amount of cutting at both ends of the crop 10 can be adjusted to a desired amount.

In addition, in the device of this embodiment, the conveyance driving force of the crop cutting device is transmitted to the crop conveyance device via the chain 70, so that both devices are linked, so that the difference in conveyance speed between the two devices can be set accurately. As a result, the crops 10 can be smoothly transferred between the mountain folds w1.

It should be noted that the present invention is not limited to such embodiments, and may take the following embodiments as examples.

(1) The above crop cutting device is equipped with a crop conveying device,
Although the crops 10 are transferred from this crop conveying device to the crop cutting device, the present invention is not limited to this, and the crops may be placed on the conveying means of the crop cutting device with one joint or the like.

(2) In the above embodiment, the lower sandwich plate 42 is completely fixed and the upper sandwich plate 42 is rotatable, but conversely, the upper sandwich plate 42 is completely fixed. , the lower clamping plate 42 may be configured to be rotatable. In this case, the same effect as described above can be obtained by urging the downstream end of the lower sandwich plate 42 in the crop conveyance direction upward by a compression spring or the like.

(3) In the above embodiment, the position of the width regulating member 40 with respect to the approach/separation table 20 is adjustable, but the invention is not limited to this, and the relative position of the width regulating member 40 and the cutter 32 can be adjusted. If so, the same effect can be obtained, and for example, by configuring the relative position of the cutter 32 with respect to the approach/separation table 20 to be adjustable, the amount of cutting at both ends of the crop 10 can be adjusted.

(4) The device of the present invention can be applied not only to onions but also to various operations requiring cutting of both ends.

[Effects of the Invention] As described above, the present invention transports the crop while keeping it on the conveyance path by restricting the movement of the crop with the width regulating member and the small diameter regulating member, and cuts both ends of the crop with a cutter. Therefore, it is possible to automatically cut both ends of the crop without performing manual work as in the past. Moreover, the cutter is installed on the contact/separation member like the width regulating member, and is always displaced together with the width regulating member, so that the shape of the crop can be adjusted.
It has the effect of being able to always keep the cutting scars at both ends constant without having to limit the size.

Further, in the apparatus according to claim 2, the width regulating member and the cutter are installed so as to be movable relative to each other in the approaching/separating direction of the approaching/separating member, and further comprising an actuating means for relatively moving the width regulating member and the cutter. Therefore, with this actuation means, the width, I
By appropriately changing the relative position of the ii1 member and the cutter, there is an effect that the amount of cutting at both ends of the crop can be made into an arbitrary section by one section.

Further, in the apparatus according to claim 3, each width regulating member has a pair of pinching members that sandwich the crop being conveyed from above and below, and at least one of the pinching members has a downstream end centered on the upstream end in the crop conveyance direction. The side end is configured to be rotatable, and the downstream end is biased in the direction approaching the other pinching member, so both ends of the crop can be moved up and down with both line members. By sandwiching between the two, it is possible to more reliably control the movement of the crop in the width direction.
