【Example】

 An embodiment of the present invention will be described with reference to the drawings, in which 1 is a disentangling machine for loosening the root stock of a strawberries seedling in which root stocks are entangled, and the treated seedling is supplied to a taping machine 2.

The taping machine 2 has roller-shaped pulleys 5 and 5 that are inclined and have a V-shaped circumferential groove in the middle between the start end side and the end end side of the machine frame 3, and those pulleys 5, 5, a conveyor belt 6 having a V-shaped ridge in the middle of the inner peripheral surface is stretched, and a V-shaped ridge inclined so as to be parallel to the conveyor belt 6 is provided on the upper side of the delivery side. The pressing belt 7 is stretched around the V-shaped pulleys 8 with peripheral grooves so that the row-shaped seedlings can be carried out while being sandwiched and conveyed. A seedling stand 10 is provided to set the seedlings to be rooted and the seedlings of the strawberries are placed, and the seedlings are thawed and supplied to the seedlings supplied from the machine 1. Reference numeral 9 is a stock conveyor belt that receives and conveys the cut end of the root.

Further, a circular saw-shaped cutter 12 screwed to a rotary shaft 11 is provided on the stem tip side of the conveyor belt 6 so that the stem tips of the conveyed seedlings are cut and aligned, and attached to a frame. A rubber plate 15 having a slit with which the outer peripheral portion of the cutter 12 fits is fixed to the tip of the protective plate 13 so as to remove the stalk scraps and juice leached from the stalk that are entrained by the cutter. .

Above the start end of the pressing belt 7 and below the end side of the conveyor belt 6, reels 17, 17 on which the winding balls of the tape 16 to be bonded are mounted are rotatably mounted. A winding spring 18 is interposed between the tapes 16 and 16 so that the tapes 16 and 16 rewound from above and below are passed through the guide rollers 20 and 20 and fixed to the shafts of the above pulleys 5 and 8 on the terminal end side of the conveyance and press-contacted. It is led to the rollers 21 and 21.

Further, a ring 23 is rotatably supported on the delivery side of the conveyor belt 6 and the pressing belt 7 by three guide rolls 22 ... Since the attached sprocket 25 is linked to the motor 26 through the speed reducer 27 and the chains 28 and 30, the ring 23 rotates. When the guide roll 22 on the stock side is driven, the sprocket attached to the shaft is driven via the chain 31 by another sprocket attached to the sprocket 25 on the tip side.

A reel 33 around which a black thread 32 is wound is rotatably and detachably supported on the ring 23, and the pulled-out thread 32 passes through a cord brake 35 and is attached to the tip of a needle 36 projecting in the vicinity thereof. The photoelectric sensor 41 attached to the bracket 40 is pushed out inward by the tension of the thread 32 at the tip of the sensor arm 38 that is drawn out from the hole and is rotatably supported by the shaft 37 of the cord brake 35. When the thread 32 is cut or lost, the sensor arm 38 is rotated outward by the centrifugal force and is received by the stopper 43 and retracts out of the sensing range of the photoelectric sensor 41. When the reel 33 and the needle 36 rotate together with the ring 23 while the yarn 32 is being supplied, the photoelectric sensor 41 emits the reflected light from the mirror 42 as a pulse signal. When the thread 32 is detected and the thread 32 is cut or lost, the detection signal disappears.

The return shaft 45 supported on the delivery side of the ring 23 is provided with a pair of rubber scraping return rollers 44, 44 having a large number of axial protrusions 44 a having a receding angle. The sprocket 46 of the return shaft 45, the sprocket 47 attached to the pulley shaft 6a of the conveyor belt 6, the sprocket 50 attached to the pulley shaft 48 at the end of the presser belt 7, and the upper and lower intermediate adjustable supports. Attached to the sprocket 52 of the shaft 51 and the shaft 49a of the upper delivery roll 49 above the return shaft 45, and the chain 55 is alternately wound up and down around the sprocket 53, and the lower one is hung around the outer periphery. Therefore, the conveyor belt 6 and the presser belt 7 rotate in opposite directions, and the scrape return rollers 44, 44 are extremely narrow on the delivery side of the rotation trajectory of the needle 36. At a position close to each other with a small gap S ₁ , it is rotated in the same direction as the conveyor belt 6 and is rotated upward while being close to the rotation locus of the needle 36 which thrusts downward into the seedling row. The needle 36 scrapes off the seedling that is about to go around and returns it upward.

The bracket 56 fixed to the machine frame near the end of the conveyor belt 6 has an inverted L shape in a side view, and the upper horizontal portion is a plan view so that the tape 16 can pass in a fitted state. The guide member 56a is notched in a U-shape, and the width of the notch portion of the guide member 56a is substantially the same as that of the tape 16. Therefore, the tape 16 is guided to a certain position from the root stock of the seedling. And glued. Further, the receiving guide member 57, which is an elastic rod whose base is fixed to the horizontal portion, gradually moves upward while regulating its position along the side edge on the stem side of the tape 16 that is pulled out obliquely from below and returns. Since it extends onto the guide roller 58 attached to the guide roller 58, it guides the tape 16 which is rewound and moves to the guide roller 58 via the guide roller 60 of the pulley shaft 6a to a predetermined position with respect to the seedling row, and at the same time, the needle. 36 will prevent the stem from pushing down and catch it around. On the other hand, the upper guide member 61 which descends from the upper part of the machine frame toward the lower side in the transport direction slides on the side edge on the root side of the tape 16 pulled out from above and guides it to the upper surface of the seedling row. Is inclined so that the tip side is higher, and the tape is also inclined so as to be parallel to the surface of the seedlings and easily moves to the root side, but the upper guide member 61 receives it and the tape of the seedlings Guide to a fixed position. Further, an inverted L-shaped stem tip guide rod 62, which is fixed to the machine frame at the lower part, extends along the stem side of the conveyor belt 6 to the lower side in the conveyor direction to support and guide the stem tips of the strawberries. To do. 63 is a switch.

When the strawberries in a row form are nipped and conveyed by the conveyor belt 6 and the pressing belt 7 and reach the vicinity of the end, the cutter 12 finish-cuts the tip of the stem and sends out from the belts 6 and 7. The tip of the stem is supported and guided by the tip of the stem guide rod 62 just before the portion corresponding to the ring 23, and the base of the stock is supported and guided by the receiving guide member 57 on the guide roller 58 on the lower side of the ring 23. The tape 16 pulled out from above is guided to a fixed position by the upper guide member 61, and the tape 16 pulled out from below is guided to a fixed position by the guide member 56a of the bracket 56 and pressure-bonded by the pressure rollers 21 and 21. The needle 36 is rotated together with the ring 23 to pull out the thread 32 and adhere to the upper and lower tapes and the receiving guide member 57. When it is wound around and is further moved in that state, it is taken up by the take-up reel 65.

11 and 12 show another example of the guide rollers 21 and 21 for pressing the tapes 16 and 16 onto the seedling row. In the example of FIG. 11, the material is sponge rubber or another elastic material. The guide roller 21 of the example shown in FIG. 12 has flanges at both ends, and the other guide roller 21 has a flange shape at both ends. Is formed so as to fit between the flanges, and the material is sponge rubber or the like as in the above example. If the guide rollers 21 and 21 are adopted, the seedlings and the tapes 16 and 16 can be prevented from shifting.
