Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stem cutting device for cutting fruit stems.

Generally, it is necessary to cut the fruit stems because they damage the surface of other fruits during processes such as fruit sorting.

In a conventional fruit stem cutting device, a fruit is placed on a conveyor belt provided with a hole, and the fruit stem is inserted into the hole and protrudes downward, and is placed close to the bottom of the conveyor belt. The fruit stalks were cut using a provided cutting device, but the stalks could not be cut short and there was a risk of damaging other fruits. had the disadvantage of cutting the clasp that holds the paper bag and damaging the blade.

The present invention provides a clamping and tensioning device below the conveyor belt for clamping and pulling the stopper of the fruit stem, and a cutting device is provided behind the transportation of the clamping and tensioning device to cut the fruit stem into short lengths. It is an object of the present invention to provide a fruit stalk cutting device that can prevent damage to the blade portion without cutting the stopper that fastens the paper bag, and can improve cutting performance. Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, 1 is a stalk cutting device, 3 is a clamping and conveying device, and 5 is a carrying out device. The fruit stem cutting device 1 is constructed as follows. That is, a conveyor belt 13 made of a thin steel plate is rotatably provided around pulleys 9 and 11 which are rotatably supported by the frame 7. 15 is a cutting device provided below the conveyor belt 13, and a rotary blade 19 is rotationally driven by a motor 17. The rotary blade 19 is located close to the lower surface of the conveyor belt 13.
This is to cut the fruit stem 23 that passes through the plurality of holes 21 provided in the stem 3 and projects downward. 25
is a paper bag that covers the fruit 27, which is squeezed at the stem 23 and fixed with a stopper 29. Reference numeral 31 denotes a gripping and pulling device provided below the conveyor belt 13 and before the conveyor of the cutting device 15, and is provided for gripping the fruit stem 23 and pulling it downward. That is,
33, 33 is a support stand 35 fixed to the frame 7
The rotating plates are fixedly fixed to rotating shafts 37, 37 which are rotatably supported by the rotating plates, and are made of an elastic material such as a rubber plate, and are arranged so that the upper parts thereof are inclined relative to each other and are in contact with each other. . Conveyor belt 13
The fruit stalks 23 conveyed by the rotary plates 33, 33 are clamped at approximately the uppermost positions, and as the rotary plates 33, 33, which rotate synchronously with the conveyor belt 13, rotate, the clamping portions move along the circumference. By descending, the stem 23 is pulled downward and cut by the rotary blade 19.

The clamping and conveying device 3 is constructed as follows. That is, 43 is a chain which is rotated by sprockets 47, 49 rotatably provided on a frame 45 provided above and parallel to the frame 7, and two chains 43, 43 are arranged in parallel. The sprockets 47, 47 are fixed to the rotating shaft 51 via keys 53, 53. 55,5
5, .
57 is connected to shafts 59 and 5 via brackets 58 and 58.
9, it is pivotally mounted so as to be swingable in the lateral direction. 6
Reference numeral 1 denotes a circular cam plate fixed to the rotating shaft 51 via a key 53 and arranged in parallel with the sprocket 47, and has a notch 63 on its outer periphery to avoid interference with the support body 55. 65 is a transport holder 57
The actuating portion contacts the cam plate 61 and rotates the transport holder 57 outward. Reference numeral 67 denotes a bullet whose both ends are connected to the conveyance holders 57, 57 and urge the respective conveyance holders 57, 57 to rotate inward. Numerals 69 and 69 are concave clamping body holders made of an elastic material that are provided opposite to the ends of the respective transport holders 57 and 57, and are provided with clamping surfaces 71 and 71 of appropriate shapes inside, such as rubber or the like. The clamping bodies 73, 73 are fitted and supported so as to be replaceable. Note that at the position on the sprocket 49 side, a cam plate (not shown) is provided in the same way as at the position of the sprocket 47 described above, and the conveyance holders 57, 57 are aligned in the direction of the arrow C in FIG.
When rotating from the direction in the direction of arrow B, the actuating part 6
5 and 65 come into contact with a cam plate (not shown), and the transport holders 57 and 57 are configured to swing in a direction away from each other.

The unloading device 5 is configured as follows. That is, 79 is a carry-out belt provided on the same plane as the conveyor belt 13 behind the conveyor of the stem cutting device 1,
It rotates around the pulley 81 etc. Note that the conveyor belt 13 and the chain 43 are configured to rotate synchronously.

In the above configuration, when the worker inserts the stalk 23 of the fruit 27 into the hole 21 of the conveyor belt 13 and places the fruit 27 on the conveyor belt 13, the fruit 27 is conveyed in the direction of arrow A in FIG. Ru. Conveyor belt 1
Conveyance holders 57, 57 that move synchronously with 3.
is moved in the direction of arrow B by the chain 43, rotated along the sprockets 47, and moved in the direction of arrow C, but the actuating parts 65, 65 are moved by the cam plate 6.
The transport holders 57, 5 are in contact with the outer peripheries of the
7 in a direction away from each other (outward),
The fruit 2 continues to move downward along the sprockets 47, 47 and is transported on the transport belt 13.
Clamping surfaces 71, 71 are located opposite to each other on both outer sides of the actuating portion 6, and are further lowered and moved in the horizontal direction.
When the cam plates 61, 65 are separated from the cam plates 61, 61, the transport holders 57, 57 are drawn together by the ammunition 67, and the clamping surfaces 71, 71 clamp the fruit 27 from both sides, synchronously with the fruit 27. Move in the direction of arrow A. When the stem 23 comes to the position of the rotary plates 33, 33, the stem 23 is clamped by the rotating plates 33, 33 together with the stopper 29 and pulled downward, and then the rotary blade 19 moves it to the upper position of the stopper 29. disconnected. The fruit 27 is conveyed while being held between the conveyance holders 57, 57, and transferred onto the conveyance belt 79. Actuating parts 65, 6 of transport holders 57, 57
5 come into contact with a cam plate (not shown) at the sprocket 49 and open in the direction of separation from each other to release the fruit 27 from being held. The fruit 27 is carried out by a carry-out belt 79. When cutting the fruit 27 of another variety with a different shape, the clamping body 73 having a clamping surface 71 corresponding to the shape is replaced and attached to the clamping body holder 69 for use.

As described above, the present invention has a conveyor belt provided with a hole for inserting the fruit stem of a placed fruit so as to protrude downward, and a lower peripheral edge portion located below the conveyor belt that is spaced apart from each other. A pair of left and right rotary plates, whose upper peripheral edges rotate close to each other, are rotated so that the upper peripheral edge portions of the left and right rotating plates approach the holes on the lower surface of the conveyor belt, thereby pinching the stopper portion of the fruit stem and rotating the conveyor belt. This fruit stem cutting device is equipped with a clamping and pulling device that rotates in the conveyance direction and pulls the fruit stem downward, and a cutting device that cuts the fruit stem on the downstream side of the conveyance side of the clamping and pulling device. Since the fruit stem is cut while holding the stopper and rotating downward in the conveying direction of the conveyor belt while pulling downward, the fruit stem can be cut well and the stem remaining on the fruit after cutting can be shortened. I can do it. Therefore, while the configuration is simple,
The stopper on the stem is located at the base of the stem, making it easy to hold the stem, and the stem can be cut into short lengths over a short distance in the direction of conveyance by the conveyor belt, making it possible to cut the fruit short during fruit sorting, etc. In addition, it is possible to prevent damage to the rotary blade by eliminating the need to cut the clasp of the paper bag.

It should be noted that the present invention is not limited to the above-described embodiments, and may be implemented in other embodiments.
