 1 is a plan view showing an embodiment of a continuous cutting lower leaf removing apparatus according to the present invention, FIG. 2 is a side view of the apparatus, FIG. 3 is a diagram showing an operating state of the leaf removing apparatus, and FIG. 4 is a leaf removing apparatus. Part (a) is a view showing the relationship between the rotary shaft and the linear body, (b) is a cross-sectional view showing the x part, and FIG. 5 is a view showing the x1-x1 part of FIG. 1 related to the cutting device. Is.

In the figure, 1 is a table on which flowers w to be processed are placed, 2 is a transportation route for transporting the flowers w one by one, and 3 is provided on a side portion in the middle of this transportation route 2. The leaf removing devices 4 are cutting devices provided on the upstream side of the cutting device 3.

The transport path 2 is designed to sequentially rise in the downstream direction f1. Specifically, the guide wheels 5a ... 5b. Provided in a state higher than the former, the endless transport chains 6 ... Are wound around the guide wheels 5a ... 5b ... And the locking rods 7 are fixed to the chains 6 at fixed intervals. In addition, the input wheel 9 fixed to the shaft 8 formed integrally with the guide wheel 5b is given a rotational force such as a motor (not shown).

The leaf remover 3 is provided with two variable-speed motors 10a, 10b on the leaf remover frame 3a, and the rotations thereof are independently transmitted from the respective motors 10a, 10b via appropriate transmission mechanisms 11a, 11b. The two rotating shafts 12a and 12b are arranged along the conveying path 2 at fixed positions on the upper and lower sides thereof, and the rotating shafts 12a and 12b are made of a large number of soft elastic materials such as rubber and urethane. The linear bodies 13 ... Of are extended.

At this time, each of the rotary shafts 12a and 12b is formed of a bar, and a through hole p is provided in the rotary shaft 12a and 12b as shown in FIG. 4 (a), and the linear body 13 is inserted through the through hole p. Then, a screw hole p1 orthogonal to the through hole p is provided, and fixing bolts 14a and 14b are screwed into the screw hole p1 from the upper and lower sides, and a spring or a lock nut is used if necessary. Then, the linear body 13 is firmly fixed. Fixing the bolts 14a and 14b from the upper and lower sides is excellent in obtaining a good balance action during rotation.

In the present invention, however, the linear body 13 is hollow, and the tubular body as shown in FIG. 4B is advantageous in terms of cost. However, the present invention is not limited to this, and for example, a closed hollow portion may be formed at regular intervals in the longitudinal direction of the linear body 13 or only a necessary portion on the tip side may be hollow. It doesn't matter. Further, it is not necessary that all of the linear members 13 made up of a large number be hollow, and it is possible to form hollow parts partially or in a scattered manner.

The cutting device 4 arranges a rotating saw blade 15 and a disk 16 vertically along a vertical surface in the transport direction, the center of rotation of the former is a fixed upper position of the transport path 2, and that of the latter is the same path. 2 is set to a fixed position on the lower side and these peripheral portions are overlapped with each other, and the rotary saw blade 15 is driven by a motor m (see FIG. 5), while the disk 16 rotates about a rotation center. In addition to fixing the driven wheel 17 to the shaft 16a, a driving wheel 19 is fixed to the shaft 18 which is the same body as the guide wheel 5a, and an endless chain 20 is hung around both the wheels 18 and 19, and also to the chain 20. The number of locking rods 21 arranged in association with the locking rods 7 is fixed so that the peripheral speed of the disk 16 substantially matches the transport speed of the transport path 2.

Reference numeral 22 is a stopper for specifying the widthwise position of the flower w on the conveyance path 2, and 23 is a guide strip that supports the flower w from below, and may be provided as necessary.

A usage example and an operation of the apparatus of this embodiment configured as described above will be described. Prior to using the apparatus, the flowers w to be treated are placed on the table 1, and a weight sorter (not shown) or the like is continuously arranged downstream of the transport path 2. After that, the product

The trader puts the device into operation, and manually supplies the flowers w one by one between the locking rods 7 ... At this time, the head of the flower w is brought into contact with the stopper 22 so that the position of the flower w on the transport path 2 is determined.

The flowers w thus supplied are obliquely raised along the transport path 2 while being supported by the locking rods 7 ... on their backs and held in the posture shown in FIG. After a certain period of time, the root of the disk 16 reaches the disk 16, and the root of the disk 16 is supported by the outer circumference of the disk 16 immediately near the point to be cut.

On the other hand, since the disk 16 is rotated in conjunction with the guide wheel 5a via the driving wheel 19 and the driven wheel 17, it supports the root of this flower w and forcibly conveys it to the downstream side for rotation. The saw blade 15 is moved to the optimum cutting position. At this time, since the outer circumference of the disk 16 is rotated and moved at substantially the same speed as the transport speed of the transport path 2, the posture of the flower w during transport is maintained in a state orthogonal to the transport direction of the transport path 2. Further, since the disk 16 maintains the root of the flower w from below even during the cutting of the rotary saw blade 15, the position of the flower w during cutting is stable. Therefore, the rotary saw blade 15 can smoothly and stably cut the extra length of the flower w in an accurate posture.

The cut flower w is further conveyed by the conveying path 2 and its root is supplied between the two rotary shafts 12 a, 12 b of the leaf removing device 3.

In the leaf removing device 3, the two rotary shafts 12a and 12b are rotated in the directions of arrows f2 and f3 by the motors 10a and 10b together with the linear bodies 13 ... .. is in a state of being tense in the radial direction due to centrifugal force. Therefore, the root portion supplied into the device 3 is struck by the linear body 13 of one rotating shaft 12a from above toward the stocker side, and the linear body 13 of the other rotating shaft 12b 13 ...・ Because it is tapped from below toward the root of the stock, this ensures that the lower leaves of the flower w are removed. Although the linear bodies 13 ... hit the stem of the flower w, the linear bodies 13 ... that collide with the stem elastically flatten with a relatively small force due to the presence of the hollow portion. It absorbs impact energy and exerts a buffering effect, and since the flattened linear members 13 ... come into contact with the stem over a large area, the local load generated on the stem during impact is generated. Is reduced and stem damage is prevented.

Thus, the flower w from which the lower leaves have been removed is further transferred in the transport path 2 and then discharged to the downstream side of the device, and such an action is performed in the transport path 2 in succession. It will be performed continuously for w.

When a weight sorter is continuously provided in the apparatus of this embodiment, the flower w discharged in this way is continuously treated by the weight sorter or the like. The unit will function as a continuous feeder of the sorter.

[0027]

[Effect of device]

 According to the present invention configured as described above, it is possible to perform the pre-shipment processing of flowers without causing a deterioration in quality.

That is, according to the first aspect, since the linear body is hollow, the impact with the stalk is greatly reduced to prevent the stalk from being damaged. In this case, the linear body 13 can be easily attached and replaced, and the workability can be improved. In addition to the advantages described in claim 3, the disk is forcibly rotated, so that the stem can be cut smoothly and stably in an accurate direction, and a neat cut end can be cut. Is what you get.
