Abstract

PROBLEM TO BE SOLVED: To make it possible to efficiently create a grafting rootstock having a fine cut surface.SOLUTION: A cut surface 1011 on a scion 101 is V-shaped and a cut surface 1041 on a rootstock 104 is y-shaped as indicated in (b) while it is conventionally Y-shaped. In the case of the Y-shaped cut surface, a fine cut surface cannot be obtained from the bottom of the V-shaped cut surface to the vertical parts if cutting (pushing and cutting) is carried out with a cutting tool comprising three blades as a single unit; therefore, if cutting is carried out by using a cutting tool with one thin blade, three processes are required. In the case of the present invention, on the contrary, two processes can be enough. For this reason, a grafting rootstock can be produced efficiently. In addition, when a scion 101 is thick, as indicated in (c), the upper part of the rootstock 104 is cleaved into two parts just to an extent equivalent to the diameter of the scion at a notch 1042 from the bottom of the V-shaped cut surface, and covers an area to the arc-shaped external edge part 1011a of the scion. Furthermore, the cut surface of a deeper notch 1044 of the y-shaped cut surface can be firmly attached without being wound up, and some sieve tubes are communicated. As a result, the percentage of rootage can be improved.

Description

  The present invention relates to an apparatus for processing a rootstock for grafting and a grafting apparatus using the rootstock processing apparatus for grafting.

  In recent years, grafting is not limited to fruit trees, but has become very widely used for vegetables, flower buds, and the like, and efficient mass production and improvement of grafting survival rate have become issues. The conventional technique of the rootstock processing aiming at the improvement of the survival rate is shown by patent document 1, for example. According to the prior art, as shown in FIG. 9 (a), when the cut surface 1011 of the hogi 101 is viewed from the side, it is V-shaped that has been used conventionally, The side view is not a conventional V-shape like the rootstock 102 shown in FIG. 10A, but a Y-shape like the rootstock 103 shown in FIG. 9 (b), FIG. 10 (b), and FIG. 11 (b) show FIG. 9 (a), FIG. 10 (a), and FIG. 11 (a), respectively, by 90 degrees around the central axis of the stem or embryo axis. It is a side view from the rotated position. Such V-shaped and Y-shaped cut surfaces 1011, 1021, and 1031 are particularly applied to plants of the lion family.

  Therefore, by forming a cut in the upper part of the rootstock 103 in a Y shape as shown in FIG. 11A, both side portions 1033 on the upper side of the rootstock 103 are formed by the cut 1032 extended from the bottom of the V-shape. , 1034 are easy to expand, and the insertion resistance of the hogi 101 is made smaller than the V shape shown in FIG.

  In addition, when the hogi 101 is thicker than the rootstocks 102 and 103, the V-shaped notch has an arcuate outer edge portion 1011a in the cut surface 1011 of the hogi 101 as shown in FIG. It protrudes from both sides 1023 and 1024 of the rootstock 102 over the entire circumference. On the other hand, in the Y-shaped notch, both sides 1033 and 1034 of the rootstock 103 are split into two portions corresponding to the diameter of the hogi 101 by the notch 1032 extended from the bottom of the V-shape. The arcuate outer edge portion 1011 a can be covered with the cut surface 1031 of the rootstock 103.

JP 2004-194544 A

  However, in the above-described prior art, since the cutting surface 1031 is a special one, the Y-shaped cutting surface 1031 is processed once by using a cutter in which three blades are integrated as in Patent Document 1. In particular, there is a problem that the portion of the cut 1032 is crushed and a beautiful cut surface cannot be obtained. In this regard, when the blade is thinned, the degree of crushing can be reduced, but there is a problem that the blade loses the fiber and the cut surface 1031 is bent. Therefore, if one blade is sequentially cut, three steps are required, which takes time.

  Further, when the tip 1012 of the hogi 101 is fitted into the extended cut 1032, as shown in FIG. To escape). Therefore, the distal end 1035 side of the cut surface 1031 of the rootstock 103 does not come into close contact with the arcuate outer edge portion 1011a of the cut surface 1011 of the hogi 101 (rolls up), and the canal and the master tube constituting the vascular bundle. Among them, there is a problem in that the outer peripheral side master tube comes off from the rootstock 103 and the viability decreases.

  An object of the present invention is to provide a grafting rootstock processing apparatus capable of efficiently producing grafts and improving the survival rate, and a grafting apparatus using the same.

  The graft processing apparatus for grafting of the present invention is an apparatus for processing the upper part of the rootstock for grafting, and has a holding member for holding the vicinity of the upper part of the rootstock and a cutter, and is supported by the holding member. From one side of the tree, cut into the blade beyond the central axis from the top to the bottom so that the cutting edge of the blade intersects the central axis of the stem or hypocotyl at a predetermined angle. The cutting tool having a first cutting member and a cutting tool, and holding the rootstock held by the holding member from a position substantially equal to the first cutting member in the vertical direction on the opposite side to the one side. And a second cutting member for cutting from the upper side to the lower side to the vicinity of the central axis so that the cutting edge of the blade intersects the central axis of the stem or hypocotyl at the predetermined angle, Forming a y-shaped cut in the upper part of the rootstock And features.

  According to said structure, by forming the cut | notch of the upper part of a rootstock in y shape, the insertion resistance of a panty can be made small compared with a V shape similarly to a Y shape, and it can insert reliably. . On the other hand, when the hogi is thicker than the rootstock, the arc-shaped outer edge portion of the cutting surface of the hogi protrudes from the rootstock almost entirely in the V-shaped cut. On the other hand, in the Y-shaped and y-shaped cuts, the upper part of the rootstock is split into two parts corresponding to the diameter of the panicles, with the cuts extending from the bottom of the V-shape. The outer edge portion can be covered with the cut surface of the rootstock.

  However, in the case of the Y shape, three steps are required when cutting with a single blade to obtain a clean cut surface. On the other hand, in the case of the y-shape as in the present invention, it can be completed in two steps. This makes it possible to produce grafts efficiently.

  In the case of the Y-shape, when the tip of the hogi is fitted into the extended cut portion, the cut surface of the extended cut is pushed out (released) substantially evenly on both sides. Therefore, the distal end side of the cutting surface of the rootstock does not come into close contact with the outer edge portion of the arcuate cutting surface of the hogi (climbs up), and the outer peripheral side of the vascular tube and the pedicle tube constituting the vascular bundle. The master tube will come off the rootstock and the viability will be reduced.

  On the other hand, when the notch at the top of the rootstock is formed in a y-shape, the extended notch is a diagonal line from the center to the outer peripheral side, and when the tip of the hogi is fitted into the hatched part, The cut surface on one side where the y-shaped cut is shallow is pushed out (escapes). On the other hand, the cut surface on the deep side of the y-letter is standing as it is (without rolling up), is in close contact with the outer edge portion of the arc-shaped cut surface of the hogi, and at least a part of the phloem is communicated. be able to.

  Thereby, the survival rate of graft can be improved.

  In the grafting root processing apparatus of the present invention, the predetermined angle is approximately 15 degrees.

  According to the above configuration, the cut surface of the V-shaped portion of the hogi and the rootstock has an apex angle of 30 degrees and the joining surface is not too wide, that is, while suppressing the decrease in the survival rate as described above. Applicability to different diameters can be ensured.

  Furthermore, in the grafting rootstock processing method of the present invention, the blade is a thin plate having a thickness of approximately 0.15 mm.

  According to said structure, the extended notch | incision can be formed from the V-shaped cutting surface of the acute angle of 30 degrees as mentioned above by using a thin-plate-shaped blade.

  Further, in the grafting root processing apparatus of the present invention, the first cutting member and the second cutting member use a common cutting tool, an arm for swinging down the cutting tool, A tilt member that tilts at a predetermined angle with respect to the central axis of the hypocotyl and switches the tilt direction between one side of the rootstock and the opposite side thereof, and a stroke by which the arm swings the blade down, A stopper that is relatively long when operated as the first cutting member and is relatively short when operated as the second cutting member is provided.

  Furthermore, the grafting rootstock processing apparatus of the present invention is characterized in that the lower side of the cutter is formed on a hypotenuse and further includes an extruding member for moving the arm forward and backward with respect to the rootstock.

  According to the above configuration, by using the cutter whose lower side of the blade edge is formed on the hypotenuse and providing the pushing member for advancing and retracting the blade, it is possible to make a cut from above to below when the blade is pushed out. .

  Therefore, when the same cut surface is formed, the stroke for swinging down the arm can be reduced.

  Further, in the grafting rootstock processing apparatus of the present invention, the holding member has a clearance groove of the cutting edge, and is disposed on the opposite side to the cutter with respect to the rootstock, and holds the rootstock from the rear side. A receiving cutting board, a y-shaped groove, a presser blade guide that is disposed on the same side as the cutter with respect to the rootstock and holds the rootstock from the front side. It is characterized by.

  According to said structure, when forming the notch | incision by extrusion of a cutter using an extrusion member, the escape of a rootstock can be suppressed by providing a receiving cutting board. Further, by providing a presser blade guide having a y-shaped groove, it is possible to suppress bending due to an impact when an extremely thin blade collides with a rootstock. By these, a cut surface can be finished smoothly and a survival rate can be raised.

  Furthermore, the grafting device of the present invention includes a spike processing device that cuts a lower part of a spike to form a V-shaped joint end surface, the root graft processing device for grafting, and the spike processing at a joint position. The V-shaped joint end face treated with the apparatus is pushed into the y-shaped joint end face treated with the rooting processing apparatus for grafting, and the grafting operation apparatus for joining is joined. A clip mounting device for mounting a clip at a junction between a certain hogi and a rootstock, and the hogi processing device, the grafting rootstock processing device, the grafting operation device, and the clip mounting device, It is characterized by comprising a conveying device for conveying.

  According to the above configuration, the survival rate can be improved by processing the rootstock, and a grafting apparatus that automatically creates a graft can be realized simply by setting the hogi and rootstock.

  According to the grafting root processing apparatus of the present invention and the grafting apparatus using the same, the cutting surface of the rootstock is y-shaped, so that even when cutting with a single blade to obtain a clean cutting surface, Cutting can be completed in two steps, so that grafts can be produced efficiently and the survival rate can be improved.

In FIG. 1 and the subsequent figures, hogi and rootstock are omitted as appropriate in order to avoid complication of the drawing.

  The rotary conveying device 2 is configured to include a pair of left and right hog chucks 21 and 22 on the upper side and a pair of left and right rootstock chucks 23 and 24 on the lower side at eight equal positions on the outer periphery. This rotary transfer device 2 delivers a hogi and a rootstock to each stage (facing devices 3 to 9) as a set every predetermined cycle, for example, every 2 seconds, and when the processing at each stage is completed, Move to the stage. Under the hogi chucks 21 and 22 and the rootstock chucks 23 and 24, receiving plates 25 for receiving soil falling from the rootstock are provided.

  The chucking operations of the hogi chucks 21 and 22 and the rootstock chucks 23 and 24 may be performed at the same timing in all the stages, or although the control is complicated, individual timings at each stage, It may be performed at different timings between the hogi chucks 21 and 22 and the rootstock chucks 23 and 24. In the example of FIG. 1, an empty space for one step is provided between the hogi processing device 5 and the rootstock processing device 6, but the interval (number of stages) between the devices 3 to 9 is Any processing apparatus may be provided as appropriate. For example, one or a plurality of devices among the devices 5 to 8 are arranged in parallel according to the type of seedling, and the processing is performed only by the corresponding device. It may be configured to pass without being performed. Therefore, the arrangement of the devices 3 to 9 is not limited to the eight equal positions of the rotary conveyance device 2, and the number of pairs of hogi chucks 21 and 22 and rootstock chucks 23 and 24 in the rotary conveyance device 2 is also limited to eight. Absent.

  The hogi introduction device 3 is generally configured to include a transport device 31 formed in a cross shape and a cutter 32. The conveying device 31 is configured to be rotatable and provided with a chuck at each of the protrusion positions of the cross. In the example of FIG. 1, the conveying device 31 is advanced 90 degrees clockwise and stopped, and the chuck facing the cutter 32 chucks the safoli whose lower end is processed, and the chuck facing the rotary conveying device 2. Then, the chucked hogi is delivered to the hogi chucks 21 and 22. For this reason, in the cutter 32, the hogi is thrown in manually or by the robot along the guide member 321, and the vicinity of the lower end of the fed hogi is cut by the rotary blade 322. A cover 323 is covered in a range not involved in the cutting of the rotary blade 322.

In the example of FIG. 1, the conveying device 41 is advanced by 90 degrees counterclockwise and stopped. The chuck facing the cutter 42 chucks the rootstock whose upper end is processed, and the chuck facing the rotary conveying device 2 The chucked rootstock is delivered to the rootstock chucks 23 and 24. Therefore, in the rotary conveying device 2, the hotwood chucks 21, 22 are idlely conveyed from the discharging device 9 to the hotwood introducing device 3, and the rootstock chucks 23, 24 are transferred from the discharging device 9. The space up to the rootstock introducing device 4 is empty.

  The safflower treatment device 5 forms an accurate V-shaped cut surface with respect to the safoli in which the lower end is cut at right angles to the axial direction and the tip length is adjusted in the safflower introduction device 3. . For this reason, when the hogi is gripped by the pair of left and right hogi chucks 51, 52, the back surface is received by the receiving cutting plates 511, 521 formed at the tips, and the front is a blade attached to the tip of the guide arm 53. The guide 531 is pressed down. At that time, the center of the stem or the hypocotyl is aligned with a predetermined reference axis (centered) and held by the inclined guide surfaces of the receiving plates 511 and 521 and the blade guide 531. In this state, the cutter 55 attached to the cutter arm 54 moves from the V-shaped guide groove formed in the cutter guide 531 to the straight guide groove formed in the receiving plates 511 and 521. The lower end portion of the stem or hypocotyl is cut into the V shape by sequentially inserting from the one side and the other side, intersecting the central axis of the stem or hypocotyl at a predetermined angle.

The drive member 6242 can swing around the pin 6245 from the mounting member 6241 by the connection with the pin 6245.

  Further, a support rod 6241d extends from a substantially central portion 6241c of the mounting member 6241, and a drive air cylinder 6243 is mounted on the support rod 6241d. A bracket 6243b is fixed to the tip of the operating piece 6243a of the drive air cylinder 6243. A pin 6246 is erected on the bracket 6243b, and the pin 6246 is fitted in a long hole 6244c formed in one end 6244a of the drive rod 6244 so as to be swingable and slidable. The other end 6244b of the drive rod 6244 is swingably attached to a substantially central portion 6242c of the drive member 6242 by a pin 6248. Further, a spring 6240 that generates an elastic force is provided between the opposing surfaces of the one end 6241a of the mounting member 6241 and the other end 6242b of the driving member 6242.

  Accordingly, when the drive air cylinder 6243 is extended, the drive member 6242 is swung from the mounting member 6241 around the pin 6245 through the bracket 6243b and the drive rod 6244 from the operating piece 6243a, thereby the cutter blade 621. Is swung down in the direction of the arrow F1, and a cut is made in the upper part of the rootstock 104. In this way, a swinging motion in the front-rear direction is realized.

  At this time, the front / rear swing mechanism 624 and the cutter blade 621 are mounted on the left / right swing mechanism 623 as described above, so that they are inclined by a predetermined angle from the axis in the vertical (vertical) direction z. Will be included. Moreover, stoppers 6271 and 6272 are provided on the frame (not shown) so as to face the front surface 6242d of the driving member 6242. As a result, the driving member 6242 is swung down until its front face 6242d abuts against the stoppers 6271 and 6272. After the abutting, the driving air cylinder 6243 extends between the mounting member 6241 and the driving member 6242. Are absorbed by the spring 6240 and the long hole 6244c and the pin 6246 provided in

  Then, by making the position of the left stopper 6271 higher than the position of the right stopper 6272, as shown in FIG. 8A, the cut from the left side is shallow with respect to the rootstock 104, and from the right side. The cuts are formed deeply. Then, as the first step, the y-shaped long side cut (first groove) 1047 is first inserted from the right side, and then, as the second step, the y-shaped short side cut (second groove) from the left side. Groove) 1048 and an unnecessary upper portion 1049 is cut away to form the y-shaped cut surface 1041 as shown in FIG. it can. Correspondingly, the front plate 6161 of the presser blade guide 616 through which the cutter blade 621 passes is formed with the y-shaped cut 6161a.

  In this way, by forming a cut in the upper part of the rootstock 104 in a y-shape, both side parts 1043 and 1044 on the upper side of the rootstock 104 are formed by the cut 1042 extending from the bottom of the V-shape, as in the Y-shape. Becomes easier to spread, and the insertion resistance of the hogi 101 is made smaller than that of the V shape, so that the insertion can be surely performed.

  In addition, even when the hogi 101 is thicker than the rootstock 104, both sides 1043 and 1044 of the rootstock 104 are formed by the notch 1042 extending from the bottom of the V-shape, so It is split into two portions corresponding to the diameter, and the arc-shaped outer edge portion 1011 a can be covered with the cut surface 1041 of the rootstock 104.

  Furthermore, when forming the Y-shaped cut surface, three steps are required to cut with a single blade in order to obtain a clean cut surface. Then, the two steps of forming the cuts 1047 and 1048 can be completed. Thereby, grafted seedlings can be efficiently produced.

  In the case of the Y-shape, when the tip of the hogi 101 fits into the extended cut portion, the cut surface of the extended cut is pushed out to both sides substantially evenly. In the case of the y-shape, the extended cut 1042 is a diagonal line from the center toward the outer peripheral side. Therefore, as shown in FIG. 8 (c), when the tip of the hogi 101 fits into the hatched notch 1042, the left side portion 1043, which has a shallow y-shaped notch, is mainly expanded (escape). The side portion 1044 on the deep cut side is standing as it is (without rolling up), and is in close contact with the arc-shaped outer edge portion 1011a of the cut surface 1011 of the hogi 101, and at least a part of The master tube can be communicated. Thereby, the survival rate of the graft can be improved.

  In addition, by tilting the cutter blade 621 downward by ± 15 degrees from the axis of the vertical (vertical) direction z that is the central axis of the stem or hypocotyl of the rootstock 104 by the left and right swing mechanism 623, The cut surface 1041 of the V-shaped portion of the rootstock 104 has an apex angle of 30 degrees, and the joining surface is not too wide. In other words, the adaptability to the different diameters as described above is ensured while suppressing a decrease in the survival rate. be able to.

  Furthermore, by using a thin plate-like blade having a thickness of approximately 0.15 mm for the cutter blade 621 that is a blade, the cutter blade 621 is extended from the V-shaped cutting surface 1041 having an acute angle of 30 degrees as described above. A cut 1042 can be formed.

  Moreover, the rootstock processing apparatus 6 of the present embodiment has a cutter blade 621 that is common to the first cutting member that forms the cut of the long side of the y-shape and the second cutting member that forms the cut of the short side. The cutting member 62 is tilted at ± 15 degrees with respect to the axis in the vertical (vertical) direction z with respect to the longitudinal swing mechanism 624 as an arm for swinging down the cutter blade 621. Left and right swing mechanism 623 as a tilting member that switches the tilt direction between one side of the rootstock 104 and the opposite side, and the stroke at which the front and rear swing mechanism 624 swings the cutter blade 621 down, When operating as the first cutting member (forming the first groove 1047), it is relatively long, and when operating as the second cutting member (forming the second groove 1048), it is relatively short. System Constituted by a stopper 6271,6272 to. Therefore, the cutting member 62 can be configured with a simple configuration.

  Furthermore, in the rootstock processing apparatus 6 according to the present embodiment, the lower side of the cutter blade 621 is formed on a hypotenuse, and a front / rear drive mechanism as an extruding member that advances and retracts the front / rear swing mechanism 624 relative to the rootstock 104. Since 622 is provided, when the cutter blade 621 is pushed out, it is possible to make a cut from above to below. Accordingly, when the same cut surface 1041 is formed, a stroke for swinging down the driving member 6242 in the front / rear swing mechanism 624 can be reduced.

  Further, the rootstock processing apparatus 6 of the present embodiment has the clearance grooves 6132 and 6142 of the cutter blade 621 in order to form a cut by pushing out the cutter blade 621 using the front and rear drive mechanism 622. By providing the receiving plates 613 and 614, the backward escape of the rootstock 104 can be suppressed. Further, by providing the presser blade guide 606 having a y-shaped groove on the front surface of the rootstock 104, it is possible to suppress bending due to an impact when the extremely thin cutter blade 621 collides with the rootstock 104. By these, the cut surface 1041 can be finished smoothly and the survival rate can be increased.

  When the rootstock processing device 6 is used as the above-described hogi processing device 5, the positions of the stoppers 6248 and 6249 are aligned, and the cut 6161a formed in the front plate 6161 of the presser blade guide 616 is V. By forming a letter shape, a V-shaped cut surface 1011 is formed at the lower end of the hogi 101. The receiving cutting plates 613 and 614 and the pressing arm 615 provided on the free end side of the arms 611 and 612 receive the hotwood from the hotwood chucks 21 and 22.

  FIG. 3 is an exploded perspective view showing a main part of the clip mounting device 8 according to the embodiment of the present invention. Also in FIG. 3, configurations that are not essential for explaining the operation of the clip mounting device 8 such as an external housing, a frame, and a power source are omitted. The clip mounting device 8 is generally provided on the rotary conveyance device 2 side, and holds the hogi chuck 21 and the rootstock 104 that are grafted by the grafting operation device 7 of the previous stage, respectively. 22 and rootstock chucks 23, 24, a clip fitting portion 81 for attaching clips to the joint portions thereof, a tube feeding device 82, a tube cutter device 83, and a seedling guide 84 provided on the rotary conveyance device 2 side. It is configured with.

  In this clip mounting device 8, the hogi chucks 21 and 22 and the rootstock chucks 23 and 24 in the rotary conveyance device 2 described above are used as the hogi chuck and the rootstock chuck. Wood chucks and rootstock chucks may be provided, and delivery may be performed from the hogi chucks 21 and 22 and the rootstock chucks 23 and 24 on the rotary conveyance device 2 side.

  In the example of FIG. 3, the clip is made of a material having elasticity, and is cut in the axial direction (slit) 8211 on one side facing the above-mentioned hogi and rootstock, and has a C-shaped cross section. A tube 821 made of is used. The tube 821 is fed to a necessary length by the tube feeding device 82 and cut by the tube cutter 83 for use.

  FIG. 4 is a perspective view of the clip fitting portion 81 and the tube feeding device 82. The tube feeding device 82 is a device that feeds the tube 821 wound around a drum or a reel (not shown) by the necessary length. The drum or reel that accommodates the long tube constitutes an accommodating portion.

  The tube feeding device 82 includes a tube feed cylinder 822, upper and lower chuck units 823 and 824, a chuck 823 on which the chuck units 823 and 824 are mounted, and a vertical movement of the slider 825, that is, a tube. And stoppers 826 and 827 for restricting the amount of feeding and a tube guide 828.

  The slider 825 is formed of a plate-like body that is guided by a guide shaft or the like as appropriate and is movable in the vertical direction. An operating piece 8221 of the tube feed cylinder 822 is connected to the upper side or the lower side (the upper side in the example of FIG. 4) of the slider 825, and the upper end surface and the lower end surface thereof are the stoppers 826, 827, respectively. It becomes a hit surface.

  The chuck unit 823 is provided with a pair of claws 8231 and 8232 supported by pins 8233 and 8234 so as to be swingable about the axis in the front-rear direction y on the slider 825 so that the distal ends thereof are closed to each other by a spring 8235. It is composed of force. Therefore, the pair of claws 8231 and 8232 sandwich the tube 821 from both left and right sides by the elastic force of the spring 8235, and when the slider 825 is displaced downward, the tube 821 is chucked and displaced together, and the upward displacement Sometimes the tube 821 is released to keep the tube 821 in place. Due to the downward displacement, the tube 821 is fed out by a length corresponding to the interval between the stoppers 826 and 827. The chuck unit 824 is configured in the same manner as the chuck unit 823 described above, and a description thereof is omitted. The feeding method of the tube 821 is not limited to the chuck units 823 and 824 provided with the claws 8231 and 8232 as described above, but may be any method such as using a feeding roller having a knurled surface on the outer peripheral surface.

  FIG. 5 is a perspective view for explaining the function of the tube guide 828. Referring to FIGS. 3 and 5, the tube guide 828 includes an attachment portion 8281 attached to the slider 825 and a protrusion 8282 formed at one end thereof. In the example of FIG. 5, the protrusion 8282 is configured by a rib obtained by bending the one end of the mounting portion 8281, and the rib is disposed between the claws 8231 and 8232 of the chuck units 823 and 824. .

  On the other hand, as described above, the tube 821 is made of an elastic material and has a C-shaped cross section in which an axial cut (slit) 8211 is formed on one side facing the hogi 101 and the rootstock 104. Consists of the body. Then, when the operator sets the tip of the tube 821 to the tube guide 828, the protrusion 8282 is set to fit into the C-shaped notch (slit) 8211. Accordingly, as shown in FIG. 5, both edge portions of the C-shaped cut (slit) 8211 are expanded from the tube guide 828 to the clip fitting portion 81, and the tube 821 is fed. The protrusion 8282 is not formed to have a uniform width as shown in FIG. 5, but the width may be increased toward the clip fitting portion 81 side (downward). A bulge may be formed at the tip of the ridge 8282.

  The tube cutter device 83 includes a cutter cylinder 831, a slide member 832, a slide base 833, and a cutter blade 834. The slide member 832 is fixed to the operating piece 8311 of the cutter cylinder 831. The slide base 833 includes a slide bearing, and guides the slide member 832 in the extending and contracting direction of the operating piece 8311. A cutter blade 834 is attached to the slide member 832 in a replaceable manner with screws 835. When the cutter cylinder 831 extends, the cutter blade 834 advances between the tube feeding device 82 and the clip fitting portion 81 to cut the tube 821.

  Referring to FIG. 4, the clip fitting portion 81 includes a tube insertion cylinder 811, a slide member 812, a pair of hooks 813 and 814, a receiving member 815, and a stopper 816.

  The slide member 812 is mounted on a slide base (not shown), and slides on the slide base in the front-rear y direction (the approach / separation direction of the hogi 101 and the rootstock 104) by the expansion and contraction of the tube insertion cylinder 811. It is freely displaceable. On the slide member 812, the hooks 813 and 814 and the receiving member 815 are mounted. The mounting of the hooks 813 and 814 and the receiving member 815 is realized by first attaching the hooks 813 and 814 to the receiving member 815 and then mounting the receiving member 815 on the slide member 812.

  Specifically, the pair of hooks 813 and 814 have ridges 8131 and 8141 that protrude from the center in the longitudinal direction (the front-rear y direction) toward the rear, and are raised toward the receiving member 815. The ridges 8131 and 8141 Is fitted into the side portion of the receiving member 815 and is pivotally mounted about the vertical axis by pins 8132 and 8142. On the other hand, on the slide member 812, ridges extending in the front-rear y direction or pins are erected with a predetermined interval in the front-rear y direction, and the receiving member 815 is provided on the ridges or pins. When the groove or the long hole formed from the bottom surface is fitted, the receiving member 815 can slide on the slide member 812 in the front-rear y direction.

  The tips 8133 and 8143 of the hooks 813 and 814 are formed with claws 8134 and 8144 that respectively engage with both edges of the C-shaped cut (slit) 8211 in the tube 821. Further, in the vicinity of the rear ends 8135 and 8145 of the hooks 813 and 814, compression springs 8136 and 8146 are provided between the inner peripheral surface facing the side of the receiving member 815 and the side of the receiving member 815, respectively. Is provided. Furthermore, guide slopes 8137 and 8147 are formed on the inner peripheral surface of the hooks 813 and 814 on the tip 8133 and 8143 side facing the side of the receiving member 815, and the guide slopes 8137 and 8147 are formed in the guide slopes 8137 and 8147. Are fitted with tube opening rollers 8139, 8149. The tube opening rollers 8139 and 8149 are pivotally supported around the vertical axis by pins 8138 and 8148 on the distal end side of the slide member 812.

  The receiving member 815 is a rod that straddles the ridges or pins erected on the slide member 812 as described above and is slidable on the slide member 812. The front end 8151 of the receiving member 815 has a receiving surface 8152 that receives the outer peripheral surface of the tube 821, and a hook 8154 that engages with the stopper 816 is formed at the rear end 8153. A compression spring 817 is interposed between the stopper 816 and the hook 8154.

  Further, in the receiving surface 8152, the C-shaped notch (slit) 8211 in the tube 821 is opposed to one diameter line, that is, at the center of the arc of the receiving surface 8152 formed in an arc shape in plan view. A protrusion 8153 for scratching the outer peripheral surface of the tube 821 is provided. In the example of FIG. 4, the protrusion 815 is constituted by a cutter blade whose blade surface height increases (cuts deep) from the top to the bottom. The height at the lowermost end of the cutter blade is, for example, 0.3 mm.

  Therefore, when the tube insertion cylinder 811 is extended, the receiving member 815 and the hooks 813 and 814 mounted on the slide member 812 are initially moved in the direction approaching the hogi 101 and the rootstock 104. Eventually, when the compression spring 817 between the stopper 816 and the hook 8154 begins to exert an elastic force, the difference in the elastic force between the compression spring 817 and the compression springs 8136, 8146 (the direction of the compression springs 8136, 8146). However, the movement of the receiving member 815 is restricted. As a result, the tube opening rollers 8139 and 8149 press the guide slopes 8137 and 8147 of the hooks 813 and 814, the tips 8133 and 8143 of the hooks 813 and 814 are expanded, and both edges of the notch (slit) 8211 of the tube 821 are expanded. The receiving member 815 and the hooks 813 and 814 move forward toward the joining portion of the hogi 101 and the rootstock 104 while the interval between the portions is expanded. Thus, the tube 821 encloses the joining portion of the hogi 101 and the rootstock 104 therein.

  When the compression spring 817 is completely compressed, the stopper 816 prevents the movement of the receiving member 815 and the hooks 813 and 814, and only the slide member 812 moves, and the tube opening rollers 8139 and 8149 are moved to the hook 813. 814 is further expanded. When the claws 8134 and 8144 are disengaged from both edges of the notches (slits) 8211 of the tube 821, the edges of the notches (slits) 8211 are contracted and closed by the elasticity of the tube 821. While being fastened to the portion, a force is applied to the receiving surface 8152 of the receiving member 815, and the receiving surface 8152 is ejected as a launch pad by the resistance.

  As a material of the tube 821 that realizes such a function, a soft plastic that can be elastically deformed within a predetermined range can be adopted as a synthetic resin material. For example, polyethylene, polypropylene, polystyrene, ABS resin (acrylic) Nitrile butadiene styrene copolymer), polyvinyl chloride (vinyl chloride), polyamide (nylon), polycarbonate, polyacetal, polyester, PTFE (polytetrafluoroethylene) and other thermoplastic synthetic resins are suitable. Moreover, not only the said thermoplastic synthetic resin but thermosetting synthetic resins, such as a phenol resin and an epoxy resin, can also be used. Furthermore, so-called elastomers such as natural rubber and various synthetic rubbers can be suitably used.

  As described above, according to the clip fitting portion 81 of the present embodiment, the tube 821 can be automatically fastened to the joining portion and the tube 821 can be removed from the hooks 813 and 814 only by expanding the tube 821 as a clip. Efficient removal, and the clipped seedlings can be automatically removed for efficiency. Further, since the projection 8153 is provided on the receiving surface 8152, when the tube 821 is extended by a predetermined length and loaded between the claws 8134 and 8144 of the clip fitting portion 81, the projection 8153 Since the outer peripheral surface of the tube 821 is scratched in the axial direction, and the projection 8153 and the scratch function as a rotation stopper for the clip, the claws 8134 and 8144 have substantially the same timing from both edges of the slit (slit) 8211. Therefore, the tube 821 can accurately protrude from the receiving surface 8152 in a substantially vertical direction.

  Furthermore, by using such a clip fitting portion 81, a tube (tube 821) in which the clip has a cut (slit) 8211 formed on one side surface such as a C-shaped cross section perpendicular to the axis is made of an elastic material. ) Can be used, so that it is very cheap compared to a so-called clothespin clip. In particular, an ordinary vinyl tube or the like is cut open at one side and cut into a predetermined length to be used as the clip, whereby the cost can be greatly reduced.

  The tube 821 has an inner diameter of, for example, 1.5 mm or 2.0 mm, and a tube having an appropriate diameter can be used by replacing the drum or reel depending on the diameter of the seedling. Alternatively, it is necessary to arrange the clip mounting device 8 by the number of tubes having the main diameter, and use the clip mounting device 8 suitable for the diameter of the seedling, so that the labor and adjustment of the drum and the reel are necessary. In such a case, the adjustment work can be saved.

  In the above-described embodiment, the tube 821 is notched (slit) 8211 in advance when it is loaded into the tube feeding device 82, but is loaded into the tube feeding device 82 from the drum or reel. In doing so, the tube feeding device 82 may be cut open.

  Referring to FIG. 3, the seedling guide 84 that functions as an end face alignment jig for the hogi 101 and the rootstock 104 is provided opposite to the clip fitting portion 81 on the rotary conveyance device 2 side as described above. It arrange | positions between the upper Hogi chucks 21 and 22 and the lower rootstock chucks 23 and 24. The seedling guide 84 includes a hogi presser 841, a rootstock presser 842, a guide member 843 for guiding the hogi presser 841 and the rootstock presser 842, and a seedling guide cylinder 844 for moving them up and down. The

  The guide member 843 includes a holding member 8431 that holds the hogi presser 841 and rootstock presser 842, a support member 8432 that holds the holding member 8431, and an elastic member 8433. The holding member 8431 is held by the support member 8432 and the elastic member 8433 so as to cause predetermined play in the left-right x direction and the front-rear y direction. The guide member 843 is advanced to the clip mounting device 8 by the seedling guide cylinder 844 at the stage where the clip mounting device 8 faces the hogi chucks 21 and 22 and the rootstock chucks 23 and 24.

  The holding member 8431 is also provided with a storage groove 8431a on the front surface (hog 101 and root 104 side), and the front of the storage groove 8431a is for introducing the ear 101 and root 104. A guide slope 8431b is formed. The hogi presser foot 841 and the rootstock presser foot 842 are stored in the storage groove 8431a.

  The hogi presser 841 includes a presser piece 8411 and an elastic member 8412. Similarly, the rootstock presser 842 is also provided with a pressing piece 8421 and an elastic member 8422. These pressing pieces 8411 and 8412 have front surfaces 8411a and 8412a formed on arcuate surfaces corresponding to the side surfaces of the hogi 101 and the rootstock 104, respectively.

  And the holding piece 8411 is formed in the V-shape which the front surface 8411a is convex on the lower side which is the side surface shape corresponding to the facing Hogi 101. Further, the pressing piece 8421 has a front surface 8421a formed in a V-shape that is concave on the upper side, which is a side surface shape corresponding to the rootstock 104 facing the pressing piece 8421a. Here, as described above, the cut surface 1041 of the rootstock 104 subjected to the tip processing by the rootstock processing apparatus 6 is y-shaped in a side view, but when pressing the side surface, both side portions of the extended notch 1042 are provided. There is no need to handle 1043 and 1044 individually, and the pressing piece 8421 is formed in the V shape.

  In this way, the press pieces 8411 for the hogi 101 and the press pieces 8421 for the rootstock 104 are urged by the individual elastic members 8412 and 8422, respectively, so that the claws 8134 and 8144 are formed in the clip fitting portion 81. The tube 821, the hogi 101 and the rootstock 104, which have come off from both edges of the notch (slit) 8211 of the tube 821 and have jumped out, are received by the pressing pieces 8411 and 8421. At this time, the hogi 101 and the rootstock 104 are The one side surface is individually pressed against the inner peripheral surface of the tube 821.

  Here, when clipping is performed, conventionally, the hogi chucks 21 and 22 and the rootstock chucks 23 and 24 are configured such that the lower part of the corresponding hogi 101 and the upper part of the rootstock 104 are substantially orthogonal to the one side view direction. By gripping from both sides in the direction, the centers of the hogi 101 and the rootstock 104 are substantially coincident (centering). Therefore, when the diameters of the hogi 101 and the rootstock 104 are different, as shown in FIG. 6A, most of the vascular bundles are shifted, the growth is poor, and the survival rate of the graft is lowered. In FIG. 6, ◯ and ● are mentor pipes constituting the vascular bundle, and Δ and ▲ are passage pipes constituting the vascular bundle.

  On the other hand, in the present embodiment, as described above, the presser foot 841 and the presser foot 841 corresponding to the hotwood 101 and the rootstock 104, respectively, between the hotwood chucks 21 and 22 and the rootstock chucks 23 and 24. A seedling guide 84 having a rootstock presser 842 is provided. Therefore, as shown in FIG. 6 (b), even when at least one side surface of the hogi 101 and the rootstock 104 are flush with each other and the diameters thereof are different, Among them, as in the range indicated by the reference symbol A, at least the outer side of the pedestal tube can be communicated with the one side surface. Thereby, the nutrient produced | generated by the hogi 101 can be supplied to the rootstock 104, and the survival rate of grafting can be improved.

  Thus, when the mounting of the tube 821 is completed after the side surfaces of the hogi 101 and the rootstock 104 are aligned, the seedling guide cylinder 844 moves the guide member 843 backward. As a result, the pressing pieces 8411 and 8421 are disengaged from the notches (slits) 8211 of the tube 821, and the tube 821 is in close contact with the outer peripheral surfaces of the hogi 101 and the rootstock 104. The seedling with the tube 821 attached thereto is transferred to the cup 93 by the arm 91 of the discharging device 9 at the next stage as described above.

  According to the grafting apparatus 1 as described above, it is efficient and low-cost, and it is automatically performed only by setting the hogi 101 and the rootstock 104 in the hogi introduction apparatus 3 and the rootstock introduction apparatus 4, respectively. A grafting device that creates a grafted seedling and discharges it from the discharge device 9 can be realized. Moreover, about the produced seedlings, a survival rate can be improved by the above-mentioned y cut in the rootstock processing apparatus 6, and also by the side alignment in the clip mounting apparatus 8. FIG.

  In the above-described example, the tube 821 is cut by the tube cutter device 83 after a long tube is drawn out by the tube feeding device 82 for a required length, but the tube cutter device 83 is cut in the middle. By inserting a (lateral slit), it is possible to cope with a difference in diameter between the hogi 101 and the rootstock 104. That is, in the state where there is no cut (lateral slit) shown in FIG. 7A, when the rootstock 104 is thick, it becomes as shown in FIG. 7B, and when the hogi 101 is thick, FIG. ), The tube 821 becomes an inclined surface 8218 at the step portion between the hogi 101 and the rootstock 104, and the inner surface of the inclined surface 8218 is not in close contact with the hogi 101 and the rootstock 104. Become.

  On the other hand, a cut (lateral slit) 8219 is formed at a height corresponding to the tip of the rootstock 104 at a right angle from the edge of the cut (slit) 8211 of the tube 821 as shown in FIG. Thus, when the rootstock 104 is thick, it becomes as shown in FIG. 7 (e), and when the hogi 101 is thick, it becomes as shown in FIG. 7 (f). In both cases, the tube 821 ′ is in close contact with the outer peripheral surface of the tube 104. By configuring in this way, the winding diameter of the tightened state can be made different above and below the cut (lateral slit) 8219, and the difference in diameter between the hogi 101 and the rootstock 104 can be dealt with. .

  The cut line (lateral slit) 8219 is not only formed from one end edge of the cut line (slit) 8211 but may be approximately half the length and formed equally from both end edges. In that case, the tube cutter device 83 is provided on both the left and right sides. Further, when the end of the tube 821 ′ is separated vertically by the cut (lateral slit) 8219, the claws 8134, 8144 of the hooks 813, 814 may also be separated vertically.
