[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic grafted seedling production apparatus for automatically joining rootstocks and scions to produce grafted seedlings.

[0002]

[Prior art]

 Generally, in cultivating vegetables, fruits and the like, grafted seedlings obtained by joining a scion of a desired plant species to a rootstock of another plant species are often used. This is because the seedlings that combine the advantages of the plant species used as the rootstock can be obtained by joining the barley and the scion to the rootstock. For example, if a watermelon scion is joined to a rootstock of Yugao, it is possible to obtain a watermelon seedling less susceptible to the vine cracking disease, which is a peculiar disease of watermelon.

In a commercial cultivation of vegetables, fruits, etc., a large amount of such grafted seedlings are required. Therefore, if the grafted seedlings were manufactured by hand, it is necessary to carry in the scion and rootstock, A huge amount of labor is required for cutting the scion and rootstock, joining the scion and rootstock, and carrying out the grafted seedling, which causes a problem that the cost of producing the grafted seedling becomes extremely high.

Therefore, in order to solve such a problem, various automatic grafted seedling manufacturing apparatuses that automate at least a part of the grafted seedling manufacturing process are disclosed in, for example, Japanese Patent Laid-Open No. 6-181633 (published article 1). Kaihei 6-50427 (Publication 2), Jitsukaihei 6-50428 (Publication 3), Japanese Examined Patent Publication 6-48940 (Publication 4), JP-A-5-23051 (Publication 5) ), JP-A-1-252228 (Publication 6), JP-A-6-141679 (Publication 7), JP-A-6-38630 (Publication 8), JP-A-3-61429 ( Publication 9), JP-A-6-70641 (Publication 10), JP-B-6-133642 (Publication 11) and the like.

[Problems to be solved by the device]

 However, the conventional automatic grafted seedling production apparatus as disclosed in the above publications, for example, have the following problems. In other words, the production process of grafted seedlings is generally carried out by the process of loading the original seedling pallet containing the spikes or rootstocks into the processing area (pallet loading step) and the spikelets or rootstocks in the seedling pallets. The process of transferring the seedlings to the splicing device (the original seedling transfer process), the process of cutting the scion and the rootstock and then joining the two (cutting and joining process), and the process of transferring the grafted seedlings to the grafted seedling pallet ( The process of transferring grafted seedlings) and the process of unloading the grafted seedling pallets containing the grafted seedlings from the vicinity of the processing plant (pallet unloading process). Cannot be sufficiently accelerated to increase the production capacity of the device.

[0006] However, all of the above-mentioned automatic grafting seedling production apparatuses disclosed in the above publications have not been able to automate all of the above steps, and the grafted seedlings can be manufactured sufficiently quickly and efficiently. However, there is a problem that the production capacity of the device is not sufficiently enhanced.

[0007] Further, when the individual grafted seedling production apparatuses disclosed in the above publications are individually viewed, it is considered that there are the following problems. That is, in the devices disclosed in Publications 1 to 3, since the scion and rootstock are taken out and transferred one by one in the seedling transfer process, the scion or rootstock located at a distant position can be transferred. When the transfer is carried out, the time required for the transfer becomes long, so that the production capacity cannot be sufficiently increased. Further, since the pallet storage section is not provided, it is necessary to manually introduce the seedling seedling pallet and discharge the grafted seedling pallet into the apparatus every time the joining process for one pallet is completed. Furthermore, since the alignment of the joint surface of the scion and the rootstock is complicated, the adhesion of the joint surface is poor and the survival rate of grafted seedlings is low.

In the device disclosed in Publication 4, the pallet carrying-in process, the original seedling transferring process, the grafted seedling transferring process and the pallet carrying-out process are not automated, so that the production capacity cannot be sufficiently enhanced. In addition, in the cutting and joining process, each operation such as cutting and joining is a sequential operation, so the cycle time is long and the production capacity cannot be sufficiently enhanced.

In the device disclosed in Publication 5, each work operation in a series of steps from the original seedling transfer step to the grafted seedling transfer step has a long cycle time and its production capacity is high. It cannot be raised enough. Moreover, since the manufacturing apparatus is expensive, the cost for manufacturing grafted seedlings is high. Furthermore, since the alignment of the joint surface between the scion and the rootstock is complicated, the adhesion of the joint surface is poor and the grafted seedling survival rate is low.

In the device described in Publication 6, the production capacity cannot be sufficiently increased because it is not automated except for the cutting and joining process. Further, since the alignment of the joint surface between the scion and the rootstock is complicated, the adhesion of the joint surface is poor and the survival rate of the grafted seedling is low.

In the device described in Publication 7, since the pallet loading process is not automated, there is a loss time for exchanging the original seedling pallet, and the production capacity cannot be increased sufficiently. Further, since the cutout portion (unnecessary portion) of the rootstock is not automatically discharged, the dischargeability of the cutout portion is poor. Furthermore, since it has a multiple structure, the operating range of each mechanism that performs clamping, cutting, joining, etc. is wide, and therefore the operating time is long and the production capacity cannot be sufficiently increased. In addition, the adhesion of the joint surface between the scion and the rootstock is poor, and the survival rate is low.

In the device described in Publication 8, since the pallet loading process and the pallet unloading process are not automated, and the pallet storage unit is not provided, a loss time for replacing the pallet occurs, and the production capacity is increased. Is not raised enough. In addition, in the cutting and joining process, each operation such as cutting and joining is a sequential operation, so that the cycle time is long and the productivity cannot be sufficiently enhanced.

The apparatus described in Publication 9 does not have a high production capacity because it is not automated except for the cutting and joining process. Further, since the device is expensive, the cost of producing grafted seedlings is high. Furthermore, the adhesion between the scion and the rootstock is poor, and the grafted seedling survival rate is low.

In the device described in Publication 10, the cutting capacity is not automated except for the cutting and joining process, so that the production capacity cannot be sufficiently increased. Further, since the device is expensive, the cost of producing grafted seedlings is high.

The apparatus described in Publication 11 has a very low production capacity because it is not automated except that the pallets are conveyed by a conveyor.

The present invention has been made to solve the above-mentioned conventional problems, and automatically and quickly joins a scion and a rootstock to produce a grafted seedling having a high survival rate. The objective is to obtain an automatic grafted seedling production device with high production capacity.

[0023]

[Action]

 According to the first aspect of the present invention, the grafted seedling production means does not operate sequentially but at the same time (at the same timing) so as to take in the rootstock, take in the cuttings, and eliminate unnecessary parts of the rootstock and the cuttings. Since excision, joining of rootstock and scion and removal of grafted seedling are performed, the cycle time of the automatic grafted seedling production equipment is shortened and the grafted seedling production is speeded up. In addition, the stems of the rootstock and the scion are substantially coaxial with each other by using an adhesive so that the end faces of the two are in contact with each other and the peripheral faces are at least partially almost linear in the axial direction. Since they are joined in a circular shape, even if the diameter of the rootstock and the diameter of the scion are slightly different, at least in the vicinity of the part where the peripheral surfaces are in a straight line, the rootstock's conduit (duct etc.) And the pipe line (conduit, etc.) of Hogi is surely connected.

In the second aspect of the present invention, basically the same operation as that of the automatic grafted seedling production apparatus according to the first aspect of the present invention occurs. Furthermore, the following effects occur. That is, in the intermittent rotation operation of the rotary table, when the rotary table stops rotating, the first opening / closing cam and the second opening / closing cam are set to the front position, and therefore, at the rootstock loading / transferring position, Each of the opening / closing cams has a large-diameter cam surface engaged with the rootstock holder or the scion holder, and both holders are in an open state (non-holding state). On the other hand, in the position of the scooping and transferring section, the first opening / closing cam engages the small diameter cam surface with the stock holder and the second opening / closing cam engages the large diameter cam surface with the stock holder, and thus the rootstock. The holder is in the closed state (holding state), while the spike holder is in the open state. Also, at the grafted seedling take-out / transfer position, both opening / closing cams engage the small-diameter cam surfaces with the rootstock holder or the scion holder, and both holders are closed.

In this state, both holders are empty at the position of the rootstock loading / transferring section, and the rootstock holder holds the rootstock at the position of the rootstock loading / transferring section, The inside of the holder is empty, and both holders jointly hold the grafted seedling at the grafted seedling take-out transfer position. After that, the rootstock is transferred to the rootstock holder by the rootstock acquisition transfer section at the rootstock transfer section, and the rootstock is held by the earstock transfer section at the rootstock transfer section. The scion is brought into the tool, and the grafted seedlings are also held by the grafted seedling removal and transfer section at the grafted seedling removal and transfer section position. That is, at the position of the rootstock loading / transferring section, the rootstock is held by the rootstock loading / loading section in the rootstock holder, while the scion holder is empty. On the other hand, while the rootstock is held by the rootstock holder at the position of the earstock transfer section, the earstock is held by the earpiece transfer section in the earpiece holder. Further, at the grafted seedling take-out transfer section position, the grafted seedling is held together by the rootstock holder, the scion holder and the grafted seedling take-out transfer section.

Next, the first opening / closing cam and the second opening / closing cam are set to the rear position, and accordingly, the first opening / closing cam uses the small-diameter cam surface as a stock holding tool at the stock loading / transferring position. When engaged, the root holder is closed and holds the root. On the other hand, the second opening / closing cam engages the small-diameter cam surface with the spike holder to hold the spike in the closed state at the spike intake / transfer section position. At the grafting seedling take-out transfer position, both opening and closing cams engage the large-diameter cam surface with the rootstock holder or scion holder, both holders are opened, and the grafted seedling is taken out. It is held only by the transfer section. After this, the rooting or scion loading section releases the rooting or scion holding. In addition, at almost the same time, the rootstock is received by the rootstock holder at the rootstock loading / transferring position, and the scion is received by the scion holder at the scooping material loading / transferring position. The grafted seedlings are delivered to the grafted seedling removal and transfer section at the transfer section.

Further, the spike holder is set to the lower position by the elevating cam immediately before reaching the adhesive application position, and the spike descends accordingly, and the lower end surface of the stem has the lower end surface of the rootstock. Abut the top surface of the stem. Then, the stalk of the rootstock and the stalk of the scion whose end surfaces are in contact with each other are joined by the adhesive application section using an adhesive. Here, the rootstock and the scion are cut at a predetermined part by the seedling adhesion stabilization cutting part at the seedling adhesion stabilization cutting part position before entering the adhesive application part position. Is made constant, so that the two are securely brought into contact with each other before entering the position where the adhesive is applied.

Thus, within a short time (for example, within 3 seconds) from the time when the rotary table stops rotating to the time when the rotary table starts to rotate again, the rootstocks are taken in and the spikes are taken in at almost the same time. Cutting of trees and stalks (removal of unnecessary parts), joining of rootstocks and stalks, and removal of grafted seedlings are performed. Therefore, the cycle time of the automatic grafted seedling production apparatus is greatly shortened, and the production of grafted seedlings is significantly speeded up.

[0029] In the third aspect of the present invention, basically, the same operation as that of the automatic grafted seedling production apparatus according to the first or second aspect of the present invention occurs. Further, among the plurality of pallets stored in the rootstock pallet storage section, the scion pallet storage section, and the grafted seedling pallet storage section, the pallets to be transferred for seedlings are automatically and sequentially supplied. Since it can be moved to a position where it can be engaged with the transfer section, scion feeding transfer section or grafted seedling supply transfer section, the pallet containing grafted seedlings can be moved from the loading of pallets containing rootstocks or spikes. The entire process up to the delivery of is automated. It should be noted that the pallets may be brought in or out of the stock pallet storage unit, the scion pallet storage unit, or the grafted seedling pallet storage unit from time to time (eg, once an hour).

In the fourth aspect of the present invention, basically, the same operation as that of the automatic grafted seedling production apparatus according to any one of the first to third aspects of the present invention occurs. Furthermore, since the rootstock supply transfer section, the scion supply transfer section, and the grafted seedling discharge transfer section respectively transfer a plurality of rootstocks, spikelets or grafted seedlings at a time, Alternatively, the time required for transferring each grafted seedling is greatly shortened, which shortens the cycle time of the apparatus and further speeds up the production of grafted seedlings.

In the fifth aspect of the present invention, basically, the same operation as the automatic grafted seedling production apparatus according to the fourth aspect of the present invention occurs. Furthermore, the rootstock or spike is taken out from the pallet by inserting the rod of the lifting mechanism into the hole of the pallet, but since the solid member is arranged above each hole of the pallet, the rootstock Or, it becomes very easy to remove the scion.

In the sixth aspect of the present invention, basically, the same operation as that of the automatic grafted seedling production apparatus according to any one of the first to fifth aspects of the present invention occurs. Furthermore, since the roots of the rootstocks are cut off on the rootstock transfer conveyor and the roots of the rootstocks are cut off on the rootstock transfer conveyor, it is possible to avoid bringing unnecessary parts into the grafted seedling production means.

As described above, before the rootstock 1b and the scion 1a enter the grafting and seedling production unit main body 2, these unnecessary portions are cut off on the conveyor in advance, so that the unnecessary portions are brought into the indexing table 3. I can't.

Further, in the automatic grafting seedling production apparatus 1, the rootstock pallet stocker 20 (rootstock pallet stocking means), the earstock pallet stocker 23 (earning pallet stocking means), and the grafted seedling completed product pallet stocker 26 (Graft stock pallet stock means) is provided. Here, the stock pallet stocker 20 includes a stock stock empty pallet storage section 20b capable of storing a plurality of empty stock pallets 21 and a plurality of stock stocks (stocks full of stock) 21. A plurality of rootstocks 1b can be taken out at a time from the rootstock-filled pallet storage section 20c capable of accommodating individual pieces and the rootstock pallet 21 with rootstocks arranged in the rootstock supply pallet storage area 20a, and then transferred to the rootstock conveyor 12. It is provided with a stock supply / transfer section 17 for transferring and a stock push-up mechanism 22 for pushing up the stock 1b in the stock pallet 21 and taking it out from the stock pallet 21. Then, the stock pallet stocker 20 automatically and automatically introduces the full stock pallet pallets 21 to be transferred into the stock pallet storage yard 20a, while the empty stock pallet pallets 21 which have been transferred are transferred. The material is automatically discharged from the stock supply pallet storage area 20a. Therefore, the stock pallet 21 automatically moves as shown by the arrows X ₁ , X ₂ , X ₃ , X ₄ .

The earstock pallet stocker 23 also has the same structure as the rootstock pallet stocker 20. The earstock empty pallet storage section 23b, the earstock full pallet storage section 23c, and the earstock supply pallet storage area 23a, It has a scion feeding / transfer section 18 and a scion lifting mechanism 25. As with the stock pallet stocker 20, the panty pallet 24 or the panty 1a is handled.

The grafted seedling completed pallet storage section 26b and the grafted seedling completed pallet stocker are stored. It is provided with a section 26c, a grafted seedling completed product discharge pallet storage area 26a, and a grafted seedling completed product discharge transfer section 19, but no push-up mechanism is provided. The seedling transfer direction and the pallet flow direction are opposite to those in the stock pallet stocker 20. Therefore, the grafted seedling pallet 31 automatically moves as shown by arrows Y ₁ , Y ₂ , Y ₃ , and Y ₄ .

In this way, in each pallet stocker 20, 23, 26, the full pallet 21, 24, 31 and the empty pallet 21, 24, 31 are automatically exchanged, but each pallet stocker When the unprocessed pallets 21, 24, 31 stored in 20, 23, 26 reach the upper limit storage amount, or become lower than the lower limit storage amount, warning lamps, buzzers, etc. notify the situation. It has become.

The specific structure of the automatic grafted seedling production apparatus 1 will be described below. As shown in FIG. 3, the rootstocks 1b are cultivated in the plurality of inverted frustoconical rootstock storage chambers formed on the rootstock pallet 21, respectively. Here, holes 21a are formed at the bottom of each root storage chamber. A plate 22a (solid member) or a ball 22b (solid member) made of a relatively hard material is provided in each root housing chamber so as to cover the hole 21a. On the other hand, at the upper end of the root push-up mechanism 22, rods 22c projecting upward are arranged at positions corresponding to the holes 21a. The root push-up mechanism 22 is configured to be capable of reciprocating in the vertical direction, and when this is moved upward, the rods 22c are inserted into the corresponding holes 21a from the lower side to the upper side. The rootstock 1b is pushed upward by this, and the rootstock 1b is taken out from the rootstock palette 21. At this time, each rod 22c pushes up the rootstock 1b via the plate 22a or the ball 22b, so that the rootstock of the rootstock 1b or the soil around the root is not deformed, and the rootstock 1b is not deformed. It can be easily retrieved. The scion pallet 24 and scion lifting mechanism 25 have the same structure.

Next, a specific structure of the indexing table 3 will be described. As shown in FIGS. 4 (a) and 4 (b), the indexing table 3 is provided with a substantially disk-shaped rotary table 3r, and the rotary table 3r has a root holder 4 and a scion holder 5. Ten seedling holders (hereinafter referred to as seedling holders 4 and 5) configured by are arranged at a constant center angle (center angle with respect to the center O) in the circumferential direction of the rotary table. In other words, the respective seedling holders 4 and 5 are arranged at positions separated by 36 ° at the central angle in the circumferential direction of the rotary table. Here, the root holder 4 is arranged on the lower side and the spike holder 5 is arranged on the upper side, but they are arranged so as to substantially overlap each other in a plan view. A soil receiver 3f for receiving soil falling from the stock 1b is provided below each stock holding unit 4. The operation of the rotary table 3r is controlled by the control panel 30, and the rotary table 3r is rotated by the same rotation angle as the above-mentioned central angle, that is, by 36 °, at a predetermined short time counterclockwise in a plan view from above (see FIG. It rotates intermittently in the direction of arrow Z _{3 in} 7.). For example, the operation of rotating for 36 seconds over 1 second and then stopping for 2 seconds is repeated. The number of seedling holders 4 and 5 to be installed is not limited to 10, but may be any desired number as long as it is 6 or more. However, when the number of installations is not 10, the above-mentioned central angle and rotation angle are not 36 °, but 360 ° divided by the number of seedling holders (for example, when 8 are 45 °).

Here, the rotation phase of the rotary table 3r is controlled by the control panel 30 so that when the rotary table is stopped, one of the seedling holders 4, 5 always comes to the front position F (stops). . Therefore, when the rotary table is stopped, one of the seedling holders 4 and 5 is always located at a position separated from the front position F by a central angle of 36 ° when viewed in the circumferential direction of the rotary table. In the following, for the sake of convenience, the front position F is referred to as the first stop position, and the positions separated by 36 ° counterclockwise from the front position F (first stop position) when viewed in the circumferential direction of the rotary table are sequentially referred to as the first stop position. 2nd stop position, 3rd stop position ... 10th stop position.

Then, in the indexing table 3, the second stop position among the first to tenth stop positions is the root receiving station 3a corresponding to the root loading and transferring section 8, and The 4th stop position is the scion receiving station 3b corresponding to the scion transfer section 9, and the 5th stop position is the seedling adhesion stabilization cutting station 3c corresponding to the seedling adhesion stabilization cutting unit 6, and the 6th stop position is The stop position is the first seedling adhesive fixing station 3d corresponding to the first adhesive applying section 7, and the seventh stop position is the second seedling adhesive fixing station 3d 'corresponding to the second adhesive applying section 7'. The tenth stop position corresponds to the grafted seedling completed product removal station 3e corresponding to the grafted seedling removal transfer section 10. The other stop positions are idle parts where no work is performed.

Each stock holding unit 4 has a cam follower 4a in contact with the cam surface of the stock holding arm opening / closing cam 4b (first opening / closing cam), and first and first cam followers 4a connected via a gear 4c. It is provided with two rootstock holding arms 4d and 4e. The root holding arm opening / closing cam 4b has a large-diameter cam surface having a large diameter (distance) from the center O and a small-diameter cam surface having a small diameter (distance) from the center O in plan view. At the connection between the large-diameter cam surface and the small-diameter cam surface, the transition angle (the diameter gradually increases) for smoothly connecting both cam surfaces by the amount corresponding to θ at the central angle (see Fig. 5). Cam surface is formed.

Here, the rootstock holding arm opening / closing cam 4b is one that opens both rootstock holding arms 4d, 4e via the gear 4c when its large diameter cam surface abuts (engages) with the cam follower 4a. When the small-diameter cam surface abuts (engages) with the cam follower 4a (non-holding state of the undercarriage), both the undercarriage holding arms 4d and 4e are closed via the gear 4c (the understock). Hold state).

On the other hand, each spike holder 5 has a cam follower 5a that comes into contact with the cam surface of the spike holding arm opening / closing cam 5b (second opening / closing cam), and a first follower connected to the cam follower 5a via a gear 5e. The second scion holding arms 5f and 5g are provided. And, in the plan view, a large diameter cam surface having a large diameter (distance) from the center O and a small diameter cam surface having a small diameter (distance) from the center O are formed on the spike holding arm opening / closing cam 5b. At the connection between the large-diameter cam surface and the small-diameter cam surface, the transition angle (the diameter gradually increases) for smoothly connecting both cam surfaces by the amount corresponding to the central angle θ (see Fig. 5). Cam surface is formed. The root holding arm opening / closing cam 4b and the scion holding arm opening / closing cam 5b have the same large-diameter cam surface, and these small-diameter cam surfaces also have the same diameter.

Here, the spike-holding arm opening / closing cam 5b is arranged to open both spike-holding arms 5f and 5g through the gear 5e when the large-diameter cam surface abuts (engages) with the cam follower 5a. When the small-diameter cam surface abuts (engages) with the cam follower 5a (in the state that the spikes are not held), both spike-holding arms 5f and 5g are closed via the gear 5e. Hold state).

Further, each of the spike holders 5 is provided with a vertical cam follower 5c that comes into contact with the cam surface of the spike moving cam 5d (elevating cam). Then, as shown in FIG. 8, the top cam surface having a high height from the bottom surface and the low cam surface having a low height are formed on the scoop moving cam 5d in plan view. A transitional cam surface (gradually changing in height) is formed at the connecting portion between the lower cam surface and the lower cam surface in order to smoothly connect both cam surfaces.

Here, when the high cam surface of the spike-moving cam 5d abuts (engages) with the vertical-moving cam follower 5c, the spike-holding portion 5 is positioned at the upper position, while (Separated state), when the lower cam surface abuts (engages) with the vertically moving cam follower 5c, the scion holding portion 5 is positioned at the lower position (rootstock / scrib contact state). .

Hereinafter, a specific structure of each of the cams 4b, 5b, 5d that controls the operations of the stock holding portion 4 and the spike holding portion 5 will be described. In the following, regarding the positional relationship with respect to the indexing table 3, the front side is simply referred to as the “front side” with respect to the rotating table rotation direction (the arrow Z ₃ direction in FIG. 7), and the opposite direction is simply referred to as the “rear side”, for convenience. Side. As shown in FIGS. 5 to 7, the root holding arm opening / closing cam 4b and the scion holding arm opening / closing cam 5b integrally rotate between a front position and a rear position as viewed in the rotating table rotation direction. You can do it. 5 and 7, both cams 4b and 5b are located at the front position, and in FIG. 6, both cams 4b and 5b are located at the rear position. Here, the center angle separation between the front side position and the rear side position, that is, the rotatable angle α of both cams 4b, 5b is a value slightly larger than the center angle θ with respect to the transitional cam surface. Has been done.

The cam surface shape of the root holding arm opening / closing cam 4b is such that the front end of the small-diameter cam surface is in the tenth stop position when it is located at the front position, as is apparent from FIGS. 5 and 7. (The grafted seedling completed product take-out station 3e) or slightly forward of this, and the front end of the large-diameter cam surface is at the second stop position (stock receiving station 3a) or slightly forward of this. Is set. The rear end of the large-diameter cam surface is located slightly forward of the 10th stop position (but rearward of the first stop position), and the rear end of the small-diameter cam surface is slightly forward of the second stop position. It is located behind the 3rd stop position. When the root holding arm opening / closing cam 4b is located at the rear position, the rear end of the large-diameter cam surface is located at the tenth stop position or slightly rearward as shown in FIG. The rear end of the small-diameter cam surface is set to the second stop position or slightly rearward of the second stop position. The front end of the small-diameter cam surface is located slightly behind the 10th stop position (but before the 9th stop position), and the front end of the large-diameter cam surface is slightly behind the 2nd stop position. It is located in front of the first stop position.

As seen from FIGS. 5 and 7, the front end of the small-diameter cam surface has the cam surface shape of the spike holding arm opening / closing cam 5b in the state of being positioned at the front position. (The grafted seedling completed product take-out station 3e) or slightly forward of this (the same position as the case of the root holding arm opening / closing cam 4b), and the front end of the large-diameter cam surface is at the 4th stop position or more than this. It is set to be located slightly to the front. The rear end of the large-diameter cam surface is located slightly forward of the 10th stop position (the same position as the case of the root holding arm opening / closing cam 4b), and the rear end of the small-diameter cam surface is the 4th stop position ( It is located slightly ahead of the Hoki receiving station 3b) (behind the fifth stop position). Then, in the state where the spike holding arm opening / closing cam 5b is located at the rear side position, as is apparent from FIG. 6, the rear end of the large-diameter cam surface is at the tenth stop position or slightly rearward from this. (The same position as in the case of the root holding arm opening / closing cam 4b), and the rear end portion of the small-diameter cam surface is set to the fourth stop position or slightly rearward thereof. The front end of the small-diameter cam surface is located slightly rearward of the 10th stop position (the same position as in the case of the root holding arm opening / closing cam 4b), and the front end of the large-diameter cam surface is closer to the 4th stop position. It is located slightly behind (on the front side of the third stop position).

As shown in FIG. 8, the scion moving cam 5d is a fixed cam (does not rotate), and its cam surface shape is such that the front end portion of the lower cam surface is at the 10th stop position (the grafted seedling completed product removal It is located slightly forward of the station 3e), and the rear end of the low cam surface is set slightly behind the sixth stop position (first seedling adhesion fixing station 3d). The rear end of the high cam surface is located slightly behind the first stop position, and the front end of the high cam surface is slightly front of the fifth stop position (seedling adhesion stabilization cutting station 3c). .

Next, a specific structure of the seedling transferring section 11 including the rootstock transferring section 8, the scion transferring section 9, and the grafted seedling transferring section 10 will be described. As shown in FIGS. 9 (a) and 9 (b), in the seedling transfer section 11, the transfer section is provided by two columns 11b (only one is shown) fixed to the base plate 2a of the grafted seedling production section main body 2. The installation plate 11a is supported. Here, the transfer portion installation plate 11a can move up and down as indicated by an arrow W ₁ . In addition, 34 is a tie rod.

The rootstock loading transfer unit 8 is connected to the transfer unit installation plate 11 a via a gear mechanism 32 and an arm 33. Further, the rootstock loading and transferring unit 8 can rotate in a horizontal plane as shown by an arrow W ₂ . Further, the rootstock loading / transfer section 8 is provided with a chuck mechanism 8a capable of holding (chucking) the rootstock 1b or releasing (unchucking) the rootstock 1b, and a rotary actuator 8b. . In addition, the scion taking-in and transferring section 9 and the grafted seedling taking-out and transferring section 10 have substantially the same structure as the rootstock taking-in and transferring section 8.

In this way, the seedling transfer section 11 (the rootstock uptake transfer section 8, the scion uptake transfer section 9 or the grafted seedling removal transfer section 10) reciprocates in the W ₁ direction and rotates in the W ₂ direction. By preferably combining the dynamic operation and the operation by the rotary actuator, the rootstock 1b on the rootstock conveyor 12 or the earstock 1a on the earstock conveyor 14 is brought to the rootstock receiving station 3a or the eararm receiving station 3b. The grafted seedlings in the grafted seedling completed product take-out station 3e can be placed (transferred) on the grafted seedling transfer conveyor 16.

The operations of the root stock holding section 4 and the spikelet holding section 5 are controlled by these cams 4b, 5b, 5d, and the operation of the root stock holding section 4 and the spikelet holding section 5 will be described below. First, the opening / closing operation of both holding parts 4, 5 caused by both opening / closing cams 4b, 5b will be described. It is assumed that the indexing table 3 (rotary table 3r) rotates intermittently in a repetitive pattern in which the indexing table 3 (rotating table 3r) rotates by 36 ° for 1 second and then stops for 2 seconds. During the intermittent rotation operation of the indexing table 3, when the rotary table 3r stops rotating, the indexing table 3 opens and closes the root holding arm opening / closing cam 4b and the hooki holding arm as shown in FIG. The cam 5b is positioned at the front position by the control board 30 (opening / closing cam control mechanism). Therefore, at the rootstock receiving station 3a, the rootstock holder 4 and the spikelet holder 5 are open (empty). At the scion receiving station 3b, the root holder 4 is closed (holds the root 1b), while the ear holder 5 is open (empty). . In the grafted seedling completed product take-out station 3e, the root holder 4 and the spike holder 5 are closed (holding grafted seedlings).

Immediately after this, at the rootstock receiving station 3a, the rootstock 1b is brought into the rootstock holding section 4 by the rootstock loading and transferring section 8, and at the rootstock receiving station 3b, the rootstock loading and transferring section. The scion 1a is brought into the scion holding section 5 by the section 9, and the grafted seedling take-out transfer section 10 holds the grafted seedling at the grafted seedling completed product take-out station 3e. That is, at the rootstock receiving station 3a, the rootstock 1b is held only by the rootstock loading and transfer section 8 in the opened rootstock holder 4, while the earstock holder 5 is empty. . At the scion receiving station 3b, the rootstock 1b is continuously held by the rootstock holding section 4, while the scion 1a is held only by the scion intake / transfer section 9 in the opened scion holding section 5. It becomes a state. In the grafted seedling completed product unloading station 3e, the grafted seedlings are jointly held by the rootstock holding section 4, the scion holding section 4, and the grafted seedling unloading and transferring section 10.

Next, as shown in FIG. 6, the root holding arm opening / closing cam 4b and the scion holding arm opening / closing cam 5b are rotated in the arrow Z ₁ direction and set to the rear position. . Along with this, at the stock receiving station 3a, the stock holding arm opening / closing cam 4b brings its small diameter cam surface into contact with the cam follower 4a, and the stock holding unit 4 is closed to hold the stock 1b. At the scion receiving station 3b, the scoop holding arm opening / closing cam 5b brings its small-diameter cam surface into contact with the scion holder, and the scion holding section 5 is closed to hold the scion 1a. At the grafted seedling completed product take-out station 3e, both open / close cams 4b and 5b bring their large diameter cam surfaces into contact with the cam follower 4a or the cam follower 5a, both holding sections 4 and 5 are opened, and the grafted seedlings are taken out. It is held only by the transfer unit 10.

Then, the both transfer units 8 and 9 release the holding of the rootstock 1b or the scion 1a, respectively, and return to their original positions, and the grafted seedling take-out transfer unit 10 holds the grafted seedlings and retains them. Return to position. Thus, the rootstock 1b is transferred from the rootstock loading and transferring section 8 to the rootstock holding section 4 at the rootstock receiving station 3a, and the earstock 1a is transferred to the rootstock receiving station 3b at almost the same time. The grafted seedlings are transferred from the loading section 9 to the scion holding section 5, and the grafted seedlings are transferred from the holding sections 4, 5 to the grafted seedling removal transfer section 10 at the grafted seedling completed product removal station 3e.

After that, the rotary table 3r starts to rotate when 2 seconds have elapsed from the stop of rotation, and rotates 36 ° for 1 second, and then stops again. At this time, the rootstock holding arm opening / closing cam 4b and the spikelet holding arm opening / closing cam 5b are rotated in the arrow Z ₂ direction at an appropriate time when the rotary table 3r rotates a little more than θ at the central angle. Returned to. Therefore, when the rotary table 3r is stopped again, the state shown in FIG. 7 is obtained. The state shown in FIG. 7 is the same as the state shown in FIG. 5 except that the rootstock 1b, the scion 1a, or the grafted seedlings held by both holding portions 4 and 5 are displaced by one. .

Next, the vertical movement of the spike holding unit 5 caused by the spike moving cam 5d will be described. The operation of the root stock holding unit 4 is not affected by the scion moving cam 5d. From the slightly rear side of the first stop position to the slightly front side of the fifth stop position (seedling adhesion stabilization cutting station 3c), the spike holder 5 has a vertical cam follower 5c which is a higher cam surface of the spike moving cam 5d. Since it abuts, it is located at the upper position. At this time, the scion holding part 5 and the rootstock holding part 4 are in a relatively vertical positional relationship as shown in the state on the left side of FIG. 4 (b). Even when the holding part 5 and the root stock holding part 4 respectively hold the scion 1a or the root stock 1b (before cutting the seedling adhesion stabilization cutting), the lower end of the scion 1a and the upper end of the root stock 1b are retained. Separated from parts (not abutting or overlapping).

In addition, the scion holding unit 5 extends from a slightly rear side of the sixth stop position (first seedling adhesion fixing station 3d) to a slightly front side of the tenth stop position (grafted seedling completed product removing station 3e). Since the vertically moving cam follower 5c contacts the lower cam surface of the scoop moving cam 5d, it is located at the lower position. At this time, the spike holder 5 and the root holder 4 are relatively close to each other in the vertical direction, as shown in the state on the right side of FIG. 4 (b). The seedlings 1a (lower end) and the rootstock 1b (upper end), which have been subjected to seedling contact stabilization cutting, are in close contact with each other.

Hereinafter, a specific structure of the seedling adhesion stabilization cutting section 6 and the first and second adhesive application sections 7 and 7 ′ will be described. As shown in FIG. 10 and FIG. 11, the seedling adhesion stabilization cutting part 6 and the first and second adhesive applying parts 7, 7 ′ can approach or retract with respect to the indexing table 3, that is, the arrow. W ₄ is attached to the slide plate 7b which can reciprocate in the direction. The slide plate 7b is driven by the slide plate drive mechanism 7c so that the slide plate 7b can reciprocate in the arrow W ₄ direction as the slide plate drive mechanism 7c rotates in the arrow W ₃ direction. It has become. Here, the slide plate 7b approaches the indexing table 3 after the indexing table 3 has stopped, and retracts before the indexing table 3 rotates again and starts.

As shown in FIG. 12 and FIG. 13, in the seedling adhesion stabilizing cutting section 6, a scion cutter 6a and a rootstock cutter which are attached to the slide plate 7b and are vertically separated from each other by a predetermined distance. 6b and a cutter cleaning tool 6c that is fixed to the immovable part (not interlocked with the slide plate) and removes (scraps) the adhered matter of the cutters 6a and 6b when the cutters 6a and 6b move. It is provided. Then, the seedling adhesion stabilization cutting unit 6 cuts the rootstock 1b and the scion 1a at a predetermined position (stem portion) when the slide plate 7b linearly moves toward the indexing table 3. (Unnecessary parts are cut off). By this cutting, the interval between the lower end of the spike 1a and the upper end of the rootstock 1b is made constant (stabilized). In the conventional automatic grafted plant production equipment, the rootstock or scion is cut by the rotating motion of the cutter.

Here, the vertical distance between the cutters 6a and 6b, that is, the distance between the lower end of the spike 1a and the upper end of the rootstock 1b after cutting is lower than the high cam surface of the spike moving cam 5d. It is the same as or slightly smaller than the height difference with the position cam surface. Therefore, when the spike holding unit 5 moves from the fifth stop position (seedling adhesion stabilizing cutting station 3c) to the sixth stop position (first seedling adhesion fixing station 3d) with the rotation of the indexing table 3. When displaced from the upper position to the lower position, the lower end of the spike 1a and the upper end of the rootstock 1b are surely brought into close contact with each other. If the gap between the cutters 6a and 6b is set to be slightly smaller than the above-mentioned cam surface height difference, the scion holding part 4 will overstroke, but the scion 1a and scion holding part 4 will Since the holding force between them is preferably set slightly loosely, a relative deviation occurs between the two, and the scion 1a and the rootstock 1b do not interfere with each other (for example, the abutting ends crush each other). (Without causing problems such as), and firmly contact and abut.

Again, as shown in FIG. 10 and FIG. 11, the first and second adhesive applying portions 7 and 7 ′ are provided with first and second adhesive feeding pipes 7 a and 7 a ′, respectively. There is. Then, when the slide plate 7b is stopped at a position close to the indexing table 3, the first and second adhesive feed pipes 7a and 7a ′ are used to attach the adhesive to the contact portion between the rootstock 1b and the spike 1a. Is applied, and the scion 1a and the rootstock 1b are adhered (joined) to each other to produce a grafted seedling. In this embodiment, the adhesive is a two-liquid type, and the adhesive supplied from the first adhesive feed pipe 7a and the adhesive supplied from the second adhesive feed pipe 7a 'are mixed. At the same time, both adhesives are solidified to bond the scion 1a and the rootstock 1b.

Thus, within a short time (within 2 seconds) from the time when the indexing table 3 (rotary table 3r) stops rotating to the time when it starts rotating again, it is possible to take in the rootstock 1b at almost the same time. The incorporation of the scion 1a, the cutting of the rootstock 1b and the scion 1a (removal of unnecessary portions), the joining of the rootstock 1b and the scion 1a, and the removal of the grafted seedlings are performed.

According to this automatic grafted plant production apparatus 1, as shown in FIG. 14, the stems of the rootstock 1b and the scion 1a are brought into contact with each other with their end faces facing each other using an adhesive, In addition, at least a part of the peripheral surfaces are substantially coaxially joined in the axial direction (straight line R) so as to be substantially coaxial. Therefore, even when the diameter of the rootstock 1b and the diameter of the scion 1a are slightly different from each other, at least in the vicinity of the portion where the peripheral surfaces are in a straight line (straight line R), the conduit of the rootstock 1b (such as a conduit). ) And the ducts (pipes, etc.) of the scion 1a are reliably connected, and the survival rate of the grafted seedlings is enhanced (in this case, if the rootstock 1b and the scion 1a are joined together with their stem centers aligned, Rate is lower). Further, the rootstock 1b and the rootstock 1a can be reliably bonded to each other without using a fixing member for the rootstock and the rootstock as in the case of the conventional automatic grafted seedling manufacturing apparatus. In this case, since the rootstock 1b and the spikelet 1a are positioned when the rootstock 1b and the spikelet 1a are held by the rootstock holder 4 or the spikelet holder 5, It is not necessary to align the complicated joint surfaces as in the case of the conventional automatic graft seedling manufacturing equipment.

Further, as described above, in the case where the scion holding portion 4 is slightly overstroked when the rootstock 1b and the scion 1a are adhered / contacted with each other after the adhesion stabilization cutting, when the scion holding part 4 is slightly overstroked, It is necessary to loosen the holding power of the stalks preferably. In this case, for example, as shown in FIG. 15 (a), it is preferable to hold the scion 1a through an elastic body 40 such as rubber. By doing so, even when the spike holding portion 4 is overstroked as shown by S ₂ in FIG. 15 (b), no trouble is caused and the spike 1a and the rootstock 1b are securely connected. Can be brought into close contact with or brought into contact.

Further, in the automatic graft planting apparatus 1, as shown in FIG. 16, the rootstock 1b is taken in, the spikes 1a are taken in, and unnecessary portions of the rootstocks 1b and the spikes 1a are cut by simultaneous operation. and joining the stock 1b and scion 1a, since the extraction of the grafted seedling is performed, it is shortened considerably can cycle time t _1, Thus the production of grafted seedling significantly faster, thus the tangent Kinae The production capacity will be greatly increased and the cost of producing grafted seedlings will be reduced. In addition, in the conventional automatic seedling production system by sequential operation, the cycle time t ₂ becomes very long (t ₂ > t ₁ ) as shown in Fig. 17, and the production capacity of grafted seedlings is sufficiently enhanced. There was such a problem.

Furthermore, in the automatic grafted seedling production apparatus 1, among the plurality of pellets 21, 24, 31 housed in the rootstock pallet stocker 20, the scion pallet stocker 23, and the grafted seedling pallet stocker 26, The pallets 21, 24, 31 to be transferred are automatically and sequentially moved to the stock supply pallet position 20a, the scion supply pallet position 23a or the grafted seedling completed product discharge pallet position 26a. The entire process from loading of pallets 21 and 24 containing 1b or scion 1a to unloading of pallet 31 containing grafted seedlings has been automated, greatly reducing the labor and speed of grafted seedling production. Therefore, the production capacity of grafted seedlings is further increased, and the production cost of grafted seedlings is further reduced. It should be noted that the carry-in or carry-out of the pallets 21, 24, 31 with respect to the rootstock pallet stocker 20, the scion pallet stocker 23, or the grafted seedling pallet stocker 26 need only be performed once (for example, once an hour) collectively.

In addition, in the automatic grafted seedling production apparatus 1, the rootstock supply transfer section 17, the scion supply transfer section 18 and the grafted seedling completed product discharge transfer section 19 are respectively provided on a plurality of machines at a time. Since the tree 1b, the scion 1a or the grafted seedlings are transferred, the time required for transferring each rootstock 1b, the scion 1a or the grafted seedling is greatly shortened, and therefore the cycle of the apparatus 1 is reduced. The time will be shortened and the production of grafted seedlings will be accelerated, which will further increase the production capacity of grafted seedlings and further reduce the cost of producing grafted seedlings.
