Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for taping a seedling of strawberries, green onions, rye or the like to fold a strip-shaped seedling into a zigzag shape.

[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]

 In the band-shaped seedlings that are folded and stacked by the known band-shaped seedling folding device, the roots of the roots are connected by tapes, but the stems are disjointed. As it descended before the section, the stems of the stacked band-shaped seedlings were disturbed, and the bulk of the stacked condition became bulky, the planting became unsmooth, and the planting posture was disturbed or felled.

[0004]

[Means for Solving the Problems]

 The present invention relates to a device for folding a strip-shaped seedling that moves downward in a horizontal direction from above from a folding device having a folding device that reciprocates in the lateral direction in a zigzag form, in which the folding device of the folding device reciprocates. In the area close to the upper part of the path, the rod that supports the tip of the seedling is folded so that the tip of the seedling that is being folded is laid horizontally so that it will come off when the seedling is folded down. The above-mentioned problems were solved by supporting them by the rods and stacking them in an unsupported state after folding.

[0005]

[Action]

 For example, the taping device continuously lowers the band-shaped seedlings, and the descending band-shaped seedlings are folded back in a zigzag shape one after another by the folding means of the folding device to stack them. The belt-shaped seedlings are held in a predetermined sideways posture by the tip of the seedlings being received by the rods, and when the seedlings are stacked, the tip end of the seedlings is removed from the rods and is already stacked and is in the lying posture. It falls on the existing seedlings and polymerizes into a neat and well-arranged posture.

 The present invention will be described in more detail with reference to an embodiment shown in the drawings. A taping device 1 includes a belt conveyor 2, a guide 3 provided on the base side of the belt conveyor 2, and a holding belt 5 provided on the upper surface of the belt conveyor 2 on the delivery side. As shown in FIG. 3, the rotating ring 6 with the needle 4 and a pair of upper and lower delivery rollers 7, and the respective shafts associated with them and the seedling table 8 are inclined about 30 degrees so that the root side becomes lower. The operator stands on the side facing the seedling mounting table 8 and, while driving the rotating parts, respectively, takes out the seedlings, for example, the root-dissolved strawberries, from the seedling mounting table 8 and places them on the belt conveyor 2. Arrange them almost continuously in strips, and pull out the tape on the upper and lower sides of the stem from the root as shown in the figure to attach the thread.The thread pulled out from the rotating needle is wrapped around the tape sandwiching the seedlings to form a striped seedling. Become. At that time, since the belt conveyor 2 and the seedling placing table 8 are gently inclined toward the worker side, it is easy to supply the seedlings and perform rooting work.

The folding device 10 provided on the delivery side of the taping device 1 includes a feeding and feeding section 11 for lifting and lowering the strip-shaped seedlings 14 delivered from the delivery roller 7 obliquely upward, and a lowered strip-shaped feeding part 11. It is composed of a folding part 12 for making the seedling 14 into a zigzag shape, and a storage part 13 for accommodating the folded band-shaped seedlings 14. The lifting and feeding part 11 is perpendicular to the axial direction of the delivery roller 7 or the like. A guide plate 15 attached to a frame plate 17 (inclined by 60 degrees with respect to the GL) for guiding the band-shaped seedlings 14 obliquely upward, and a band-shaped seedling 14 sandwiched above the guide plate 15 supported by a sprocket. A pair of guide rollers 16 and 16 that are continuously lowered (the axial center direction is parallel to the feed roller 7 and the like) and a lower portion of a pair of left and right swinging rods 18a and 18a that are upwardly U-shaped when viewed from the feed direction. It can be freely rotated with the connecting rod 18b. The connecting rod 18b bypasses the tip of the descending stalk of the strawberries.

The folding and stacking portion 12 has a plate surface inclined at the same angle as that of the frame plate 17, and a cam in which a substantially horizontal guide groove 19 having a sloped portion 19a and a standby portion 19b following the inclined portion 19a is formed near both sides. The plate 20 and a pair of folding rollers 21a. 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 for pressing and stopping 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 in a portion facing the upper part of the movement locus of the folding rollers 21a, 21b. As seen from below, a U-shaped downward rod is installed, and the legs on both sides are erected from the frame body of the cam plate 20. The rod 38 is a belt-shaped seedling 14 (stems are fixed. (Cut to size) to prevent the posture from being disturbed and the stem from being caught in the folding rollers 21a and 21b.

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 slidable cylinder 48 having a protruding piece 47 is vertically slidably and rotatably fitted on the inclined shaft 46, and the sliding cylinder is attached to the base of the receiving plate 50 whose tip faces the other support frame 40. Attaching bosses that straddle 48 up and down, loosely fit these bosses on the inclined shaft 46, and attach them to the tip of the receiving plate 50. By supporting 51 by the other supporting frame 40, the receiving plate 50 can be moved up and down along the supporting frames 40, 40, and as shown in the drawing, the receiving posture extending between the left and right supporting frames 40, 40 and the inclined shaft 46. It is configured so that it can be converted into a retracted posture in which it is pivoted outwards around the center of the belt-shaped seedlings 14 that are folded above the left and right support frames 40, 40 in a folded state. Guide rods 49, 49 are provided for receiving and guiding the middle portion of the stem so as not to project laterally.

Next, the transmission device will be described. An input sprocket 52 rotatably supported on the outside of the main frame 41 by an input shaft 41a is provided by a sprocket 55 attached to the shaft of the delivery roller 7 via 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, and when the sliding cylinder 48 is rotated to fit the protruding piece 47 between the connecting pins 71, the rotation of the chain 70 causes the receiving plate 50 to slowly descend. 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 by pressing strongly while laying down the drooping band-shaped seedling 14, and the receiving rod 38 receives and supports the tip of the drooping band-shaped seedling 14 and the folding roller 21b fixes the root part. When laid, the tip of the stem disengages from the rod 38 and overlaps with the stem of the band-shaped seedling 14 folded in the previous step, and when approaching to the side, the leading folding roller 21a causes the guide groove 19 to tilt. It rises along the portion 19a and moves to the standby portion 19b. At that time, since the shaft 25 of the folding roller 21a pushes up the control plate 35, the seedling holding rod 31 is rotated upward against the spring 32, and is separated from the bent portion of the folded band-shaped seedling 14 to move. When reaching the vicinity of the terminal end, the shaft 25 and the notch 37 of the control plate 35 coincide with each other. At that time, since the seedling pressing rod 31 is biased downward by the spring 32, the seedling pressing rod 31 is pivoted downward together with the control plate 35 and is turned. The protrusion 31a pierces and presses the band-shaped seedling 14 wound around the folding roller 21b.

Next, when the swing arm 22 swings to the right, the right folding roller 21b leads, while the left folding roller 21a rapidly descends along the inclined portion 19a following the swiveling roller 21b. 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.

Since the feed shaft 62 slowly rotates the chain 70 during the folding operation described above, the backing plate 50 is slowly lowered by an amount corresponding to the folding thickness, and when the backing plate 50 reaches the lower end of the scraper 76. When the taping device 1 is stopped, the folding device 10 interlocked with it is also stopped. Therefore, the uppermost bent portion of the band-shaped seedling 14 is cut with a knife, and the receiving plate 50 is pivoted outward and retracted. After that, the folded banded seedlings 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 and the receiving plate 50 is returned. It is rotated to return to the upper side, the end of the band-shaped seedling is fixed to it, and taping work and folding work are started.

[Effect of the device]

 The present invention relates to an apparatus for folding and folding a strip-shaped seedling 14 which is horizontally laid down from above from the upper side in a zigzag shape by a folding apparatus 10 having a folding means. At the position close to the upper part of the reciprocating path, a rod 38 for supporting the tip of the seedling was laid horizontally so that it could be removed when the strip-shaped seedling 14 was folded and descended. When the seeds are folded by the folding means, only the stems do not fall apart and fall onto the strip-shaped seedlings 14 that have already been folded prior to the root, and the tip is received and folded without disorder. Can be stacked. As a result, it is possible to prevent the bulk from becoming abnormally large when folded into multiple layers, and to pull out the band-shaped seedlings neatly at the time of planting.
