Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for taping seedlings of strawberries, green onions, rye or the like, and folding the strip-shaped seedlings into a zigzag shape and accommodating them.

[0002]

[Prior Art]

 Conventionally, an apparatus for folding a tape-shaped banded seedling into a zigzag shape and packing it in a storage container has been already known from JP-A-2-76508.

[0003]

[Problems to be solved by the device]

 The known band-shaped seedling folding device housing contains the band-shaped seedlings folded in a zigzag shape inside the box, so it is difficult to take out the seedlings, and the band-shaped seedlings may be cut and the efficiency is low. there were. In order to solve such a problem, both sides of the folded belt-shaped seedlings were released, and the lower surface of the belt-shaped seedlings was received by a receiver that descends according to the increase in the folding thickness. The stalks of the band-shaped seedlings fell outward, causing seedling collapse.

[0004]

[Means for Solving the Problems]

 According to the present invention, a folding and stacking part for folding the strip-shaped seedlings in a folded shape is provided in the lower part of the supply part for continuously lowering the strip-shaped seedlings, and the side and the upper part are opened immediately below the folding and stacking part. A seedling storage unit is provided, and receiving units that receive the folded band-shaped seedlings and that descend according to the increase in the folding thickness are arranged in the seedling storage unit, and on both sides of the descending range of the receiving unit. The above-mentioned problems were solved by providing a guide member that slidably contacts the stem portion of the folded banded seedling.

[0005]

[Action]

 In the taping process, since the transport surface of the taping device is inclined so that the root side becomes lower, the roots can be easily aligned. Also, since the band-shaped seedling folding surface of the folding device has the same inclination angle as the conveying surface of the taping device, all the transmission shafts of those devices have the same inclination angle, and smooth transmission is performed. be able to. Also, when the folded banded seedlings are stored in a storage container whose stem tip side is open, even if the number of folds is large, the root side is sufficiently lower than the stem side, so the upper layer banded seedlings may slip off. Absent.

Which are reciprocally rolled left and right while being regulated by the boss portion being loosely fitted in the guide groove 19. 21b and a reciprocating drive mechanism 26 in which the upper end of the swing arm 22 which swings left and right around the lower fulcrum shaft 22a is connected to the shaft 25 of the folding rollers 21a and 21b via links 23 and 23. And a locking mechanism 27 that presses and holds the bent portion of the band-shaped seedling 14.

The locking mechanisms 27 are respectively provided at portions corresponding to both ends of the guide groove 19, and one end of a support shaft 30 rotatably supported by the frame member 28 is attached to the seedling pressing rod 31. The base is fixed, the tip is bent in the stem direction of the seedling, and the protrusion 31a that pierces the tape 14a of the band-shaped seedling 14 is attached, and the middle portion is lowered by the spring 32. The lower limit of the downward movement is restricted by a stopper 33, and a boss 35a of a control plate 35 is rotatably fitted to the other end of the support shaft 30 and a long hole 35b is formed in the boss 35a in the circumferential direction. A pin 36 which is integral with the support shaft 30 is inserted into the elongated hole 35b, and the pin 36 and the control plate 35 are connected by a tension spring 34 to normally urge the control plate 35 and the seedling retainer. The rod 31 and the rod 31 form a certain angle, On one side of the control plate 35, there is provided a notch 37 through which the end of the shaft 25 of the folding rollers 21a (or 21b) passes, and a band-shaped seedling is provided at a portion facing the movement path above the folding rollers 21a, 21b. A substantially horizontal receiving rod 38 is installed to receive the tip portion of 14 (the stem is cut to a certain size) and prevent the winding rollers 21a and 21b from being wound around.

The storage unit 13 is configured as follows. The support frame 40 has a gentle inclination of 15 degrees (45 degrees with respect to GL) with respect to the main frame 41 which is in the same direction as the frame plate 17, and has a short L-shape inside the left and right support frames 40. A scraper-shaped seedling receiving plate 45 which fixes the receiving pieces 42, 42 and serves as a storage body has an upper end protruding from the thin inheriting plate 43 bent in an upward dogleg shape and the inner surface of the support frame 40. It is inserted between the receiving pins 43a, 43a, and the lower part is superposed on the upper surfaces of the receiving pieces 42, 42 so as to be detachably mounted and supported along the outside of one supporting frame 40. A sliding cylinder 48 having a protrusion 47 is vertically slidably and rotatably fitted on the inclined shaft 46, and the sliding cylinder is attached to the base of the receiving body 50 whose tip faces the other supporting frame 40. Attaching bosses straddling 48 vertically, these bosses are loosely fitted on the inclined shaft 46, and the bosses mounted on the tip of the receiving body 50 are attached. By supporting 51 by the other support frame 40, the receiving body 50 can be moved up and down along the support frames 40, 40, and the receiving posture between the left and right support frames 40, 40 as shown in the drawing and the tilt shaft 46. It is configured so that it can be converted into a retracted posture in which it is pivoted outwards about.

Further, a pillar that is erected on the outer side of the left support frame 40 and a pillar that is erected on the right main frame 41 and that bypasses the outside of the tilt shaft 46 are folded up. Guide rods 49, 49 are provided as guide members to guide and guide the stems of the strip-shaped seedlings 14 which slide down in the vertical direction so that the stems do not project outward. The part corresponding to the folding rollers 21a, 21b is curved outward, and the lower end faces the vicinity of the part corresponding to the receiving piece 42, but the one on the right side rotates the receiver 50 outward. There is a vertical gap with respect to the receiving piece 42 to the extent that it can be moved. Although the guide member is illustrated as a bar, it may be formed of a plate.

Next, the transmission device will be described. The input sprocket 52 rotatably supported by the input shaft 41a on the outer side of the main frame 41 is sprocket 55 attached to the shaft of the delivery roller 7 via the chains 53 and 54. The small sprocket 56, which is driven and mounted on the input shaft 41a, drives the sprocket 60 of the rotating shaft 58 supported on the lower portion of the main frame 41 via the chain 57, and has a small diameter provided at the end of the rotating shaft 58. When the disk surface of the disk 63 at the end of the feed shaft 62 which is installed between the support frames 40 and 40 is attached to the friction wheel 61 by the spring 65 with the feed shaft 62 to convert the power transmission direction to a right angle, the speed is reduced together. , The connecting pins 71 ... Of the chain 70 hung on the sprocket 68 attached to the other end of the feed shaft 62 and the sprocket 69 pivotally supported on the upper portion of the main frame 41, Each of them protrudes to the side. When the sliding cylinder 48 is rotated to fit the protruding piece 47 between the connecting pins 71, the receiving body 50 is slowly lowered by the rotation of the chain 70. The crank arm 66 fixed to the rotary shaft 58 is interlocked with the swing arm 22 via a link 67, so that the swing arm 22 reciprocates left and right about the fulcrum shaft 22a. Further, the belt 73 hung on the pulley 72 attached to the lower end of the input shaft 41a is hung on the sprockets attached to the guide rollers 16 and 16 and the sprocket 75 pivotally supported on the side thereof in the opposite direction. Since it has been swung around, the guide rollers 16 and 16 feed the sandwiched strip-shaped seedling 14 downward.

The operation will be described below. The feeding speed of the feeding roller 7 of the taping device 1 and the winding and feeding speed of the guide rollers 16 and 16 are the same, and the average folding speed of the folding device 10 is also the same as the above speed. However, since the swing arm 22 is driven by the crank arm 66 as described above, the folding rollers 21a and 21b reciprocate rapidly at the middle of the guide groove 19 and slowly at both sides while temporarily stopping. As a result, the drooping band-shaped seedlings 14 become largely slack when the folding rollers 21a and 21b are on both sides, but the swing guide 18 returns to the center side by its own weight and swings to eliminate the slack.

Further, when the folding rollers 21a and 21b roll from right to left in the figure, the preceding folding roller 21a rolls while suppressing the expansion of the band-shaped seedling 14 that has already been folded. Then, the following folding roller 21b rolls while pressing down strongly while laying down the hanging belt-shaped seedling 14, and when approaching the side part, the preceding folding roller 21a rises along the inclined portion 19a of the guide groove 19. And shifts to the standby section 19b. At that time, the shaft 25 of the folding roller 21a pushes up the control plate 35, so that the seedling pressing rod 31 rotates upward against the spring 32, and is separated from the bent portion of the folded strip-shaped seedling 14 to end the movement. When reaching the vicinity, the shaft 25 and the cutout portion 37 of the control plate 35 coincide with each other. At that time, since the seedling pressing rod 31 is urged downward by the spring 32, the seedling pressing rod 31 is rotated downward together with the control plate 35 and is protruded at the tip. 31 a pierces and presses the band-shaped seedling 14 wound around the folding roller 21 b.

Then, when the swing arm 22 swings to the right, the right folding roller 21b precedes, while the left folding roller 21a rapidly follows along with it and rapidly descends along the inclined portion 19a. The fold portion is flattened by being crushed by riding on the fold portion, and on the other hand, the end of the shaft 25 of the folding roller 21a rides on the control plate 35 and resists it against the tension spring 34. When the shaft 25 passes over the control plate 35 by descending in the range of the hole 35b, the control plate 35 is pulled up by the tension spring 34 and returns to the standby position where it crosses the inclined portion 19a.

During the above-described folding operation, the feed shaft 62 slowly rotates the chain 70, so that the receiving body 50 is slowly lowered by an amount corresponding to the folding thickness, while the guide rods 49 and 49 are folded. When the taping device 1 is stopped when the receiver 50 reaches the lower end of the scraper 76, the stem of the banded seedling 14 is received and guided while preventing it from protruding outward or falling down. Since the folding device 10 interlocked with it is also stopped, the uppermost bent portion of the band-shaped seedling 14 is cut with a knife, and the receiving member 50 is pivoted outward and retracted, and then the folded band-shaped member. The seedling 14 can be taken out together with the scraper 76 and stored in a storage box. When the work is restarted, a new scraper 76 is set, the receiving body 50 is returned and rotated, and the sliding cylinder 4 8 The projection piece 47 is disengaged from the connecting pin 71 of the chain 70 by rotating, and the receiving body 50 is raised in that state, and then the sliding cylinder 48 is returned and rotated to move the projection piece 47 to the connecting pin 71, It is fitted between 71, the end of the band-shaped seedling is fixed to it, and taping work and folding work are started.
