Description

  The present invention relates to a covering guide for collecting a covering material in a field management device for facilitating initial work preparation when winding and recovering a covering material such as a cold koji directly on a teacup, for example. .

For example, in tea cultivation, there is a case where so-called direct hanging is performed by directly covering a teacup with a covering material such as a cold koji for a certain period of time for the purpose of shading, removing frost, improving quality, and the like. This is because coated and cultivated tea has improved taste, color and fragrance, can meet consumer preference requirements, and can improve profitability.
The covering material used for this type of covering cultivation is usually formed into a slender shape in accordance with the formation state of the cocoon, that is, the tailored state. It is a long sheet shape having a constant width of about 50 m. Moreover, as a package of the covering material before covering with a teacup, it is in the state wound by roll shape. The covering material in this state is hereinafter referred to as a “winding roll”.

  And various methods and apparatuses have been devised in such a case that such a covering material is unrolled and covered in the unfolded state, or the covering material in a state of being covered on the reed is wound into a roll shape (for example (See Patent Documents 1 to 4). In these conventional methods, it has been common to monitor the winding of the covering material and to arrange dedicated assist personnel for continuously and smoothly performing the winding operation. The fact that such assistants must be arranged separately in addition to the operators who operate the equipment is a significant burden on humans and labor, especially for tea farmers and other people whose farming population is decreasing. In addition, because of the increased cost, it was a big problem.

  For this reason, we have developed a new coating material winding and unfolding device that can wind up the coating material neatly and continuously without requiring a dedicated assistant to smoothly wind up the coating material. One of the applicants has already been involved in the process of patent application (Patent Documents 5 and 6).

  According to the various inventions of the present applicant, smooth winding and collection of the covering material has been achieved, but there has been pointed out room for further improvement when focusing on the actual working mode. That is, when starting the winding of the covering material, an operation of fixing the winding start end portion to the winding shaft of the winding shaft device is performed, but it has been pointed out that the work is difficult to perform. Specifically, the covering material on the teacup was set to pass in a zigzag manner through each of the three guide bodies of the receiving guide body, the intermediate guide body, and the winding guide body in this covering material guide device. Thereafter, the starting end is fixed to the winding shaft. Fixing the starting end while changing the direction of the passing direction of the covering material is an extremely troublesome work, and the improvement thereof has been demanded.

  The mode for carrying out the present invention includes one described in the following examples, and also includes various methods that can be improved within the technical idea.

  As shown in FIG. 1 and FIG. 2 as an example, a farm management device 1 to which the present invention is applied includes a traveling machine body 2 that travels across a covering target T such as a teacup, and a covering object that is covered by the traveling machine body 2. The covering material processing unit 3 is supported so as to be positioned on the upper surface of T. That is, the farm management apparatus 1 shown in the present embodiment has a structure in which the covering material processing unit 3 is mounted on the traveling machine body 2 of a riding type teacup-type tea garden management machine that is often used in a tea garden. To do.

  Here, the “farm management work” by the “farm management device 1” will be described. The “farm management work” refers to performing an intended work by attaching an appropriate management device unit to the traveling machine body 2 according to the work content. That is, in the case of a tea plantation that is an example of a farm, as a management device unit, a pruning machine unit that prunes a trunk to prepare a tree shape and restores the tree vigor, and a plucking machine that plucks tea leaves A unit or a fertilizer application / control unit that spreads fertilizer, chemicals, etc. on a teacup is well known. In this embodiment, the covering material processing unit 3 is applied as a management device unit.

A typical example of the covering target T is a teacup, and the same reference numeral “T” is given to the teacup in this specification as well, but the covering target T is not necessarily limited to the teacup T. For example, it may be a straw of crops other than tea, such as lettuce, cabbage, onion, etc., or the soil surface of a mulching target, and in this sense, it is a coating target T. Further, in this specification, the term “mochi” may be used simply in the sense that the covering target T is not limited to the teacup T only.
Furthermore, as described above, since it is assumed variously as the coating target T, the coating material S is not limited to the cold chill commonly used in tea gardens, but a chemical fiber sheet, a nonwoven fabric sheet, a mulching sheet, etc. However, it is also possible to apply woven or bamboo woven long sheets.
Hereinafter, the traveling machine body 2 and the covering material processing unit 3 constituting the farm management apparatus 1 will be described.

First, the traveling machine body 2 will be described. The traveling machine body 2 travels on the ground between the teacups T, and has a frame 21 formed in a gate shape substantially in accordance with the conventional method when viewed from the running direction, that is, the longitudinal direction of the teacup T. A member. This frame 21 is attached to the left and right leg frames 21A that move into a standing state between the ribs, a connecting frame 21B that connects the front, rear, left and right leg frames 21A upward, and a leg frame 21A that can be raised and lowered. The lift bracket 21C is provided. Incidentally, for example, the plucking machine unit can be attached to the elevating bracket 21C. In this case, the plucking machine unit is provided at a substantially middle position (intermediate in the front-rear direction) of the traveling machine body 2. This is for the purpose of understanding that various usage modes are provided, and in the recovery of the covering material S in the present invention, the picking machine unit is not attached.
Moreover, the traveling body 22 which applied the crawler as an example is provided in the lower end of the leg part frame 21A. Of course, this traveling body 22 is not limited to such a crawler, but a form in which a pneumatic tire that does not excessively press the saddle, or both are applied (for example, a form in which a pneumatic tire is applied to the front side and a crawler is applied to the rear side). Etc. can be taken as appropriate.

  Further, on the upper part of the connecting frame 21B, controls for controlling and operating the control seat (operator seat) 23, the control stick 24, and the farm management apparatus 1 where an operator who has boarded the farm management apparatus 1 sits. A box 25 is provided. A motor 26 to which, for example, a diesel engine is applied is mounted on the side of the driver's seat 23. As an example, a hydraulic pump (not shown) is driven by the motor 26 and supplied by the hydraulic pump. The hydraulic fluid is used to drive the traveling body 22, drive a winding shaft 40 of the covering material processing unit 3 described later, and further drive a cylinder (not shown) responsible for the lifting and lowering movement of the lifting bracket 21C.

An adapter member for attaching the covering material processing unit 3 to the traveling machine body 2 so as to be positioned above the teacup T is provided.
Specifically, an elevating guide member 27 including a pair of left and right elevating guide brackets 27A and elevating receiving rollers 27B is provided at the front end portion of the frame 21, and a pair of left and right elevating adapters 28 are supported on the elevating guide member 28. In addition, each raising / lowering adapter 28 of each right and left can change an raising / lowering position separately. A specific configuration of the elevating adapter 28 is configured by an elevating post 28A that extends vertically in the shape of a long eave and is directly supported by the elevating guide member 27, and an adapter rod 28B that extends forward below the elevating post 28A. A conventionally known mechanism is adopted as a mechanism for raising / lowering shift. As an example, a method of pulling up a shift cable connected to the lower end of the raising / lowering post 28A by a cylinder or the like is employed.

A skid member 29 is further provided around the leg frame 21 </ b> A in the traveling machine body 2. The skid member 29 is a member for preventing the vicinity of the leg frame 21A in the traveling machine body 2 from being caught by interference with the tea tree skirt of the teacup T, the covering material S suspended from the teacup, or the like. is there.
First, as a first embodiment of the skid member 29, a cover sheet 291 is applied. The cover sheet 291 is, for example, a transparent resin sheet or the like, and is a flexible member as a whole, but has a certain stiffness, and a transparent vinyl sheet having a thickness of about 3.0 mm is used. You may apply. In short, the cover sheet 291 has a surface hardness to such an extent that the tip of the stem will not pierce even if it touches the sharp stem of the teacup skirt of the teacup T. It is only necessary to elastically push back and obtain a smooth rubbing state.
This may have a length that covers the entire side surface of the leg frame 21A, for example, or may be divided into appropriate dimensions. In any case, a plurality of hook receiving holes 291a are provided at appropriate positions on the cover sheet 291 and are fixed so as to be fitted into hook-shaped skid fixing portions 210 in the leg frame 21A and the connecting frame 21B, for example. Of course, as shown in FIG. 7, a cover sheet 291 as an example of the skid member 29 may be provided around the leg frame 21A using a hook strap 291b.

As the skid member 29, a hard cowl 292 having a shape that smoothly covers the leg frame 21A and its peripheral devices may be applied in addition to the cover sheet type. Specifically, an FRP material, a resin molding material, and an aluminum pressing material can be applied. In this case, the shape of the skid member 29 itself can be set to a more strict dimension, and the interference between the tea tree skirt portion of the surrounding teacup T and the covering material S stretched in the unfolded state on the teacup T is further increased. Can be effectively prevented. For example, the hard cowl 292 can be divided into left and right parts, and the hard cowl 292 is formed in the middle to cover the leg frame 21A. Reference numeral 293 denotes a fixing pin that is combined with bolts and nuts so that both are in the middle and the bracket-like skid fixing part 210 in the frame 21 is fastened together. Of course, in consideration of workability, in addition to a screw-like fixing method, a bayonet-engaged pin member called a quick fastener may be used.
In any case, it is preferable that the hard cowl 292 is formed in a recessed state as shown in FIG. 8 in the receiving portion 210A of the fixing pin so that the fixing pins themselves are not caught and cause interference.

Next, the covering material processing unit 3 constituting the covering material collection guide mechanism according to the present invention will be described. The covering material processing unit 3 is composed of a winding shaft device 4 and a covering material guide device 5 which will be described later, and a member which becomes a frame for supporting them, and as described above, a cold chill directly covering the ridges to be coated T, etc. The coating material S is wound up in a roll shape. On the other hand, this can also be applied in the case of performing the unfolding operation, that is, the operation of feeding out the roll-shaped covering material S and placing it on the teacup T. In addition, about the coating | coated material S, the thing of the state wound up especially is demonstrated also as the winding roll SR as needed.

At this time, as described above, the left and right adapter rods 28 </ b> B can be independently set in height, and the covering material processing unit 3 can be tilted in the left-right direction and mounted on the traveling machine body 2. The mounting method tilted in this way is effective when working in a teacup T on an inclined ground.
In the embodiment described below, a type that does not allow such inclined mounting will be described.

  The covering material processing unit 3 is attached to the front part of the traveling machine body 2, which is already deployed on the teacup T with the traveling machine body 2 moving forward, in other words, with the operator normally facing forward. This is because the winding work of the covering material S in the finished state can be performed. For this reason, if the coating material processing unit 3 is used as it is and the coating material S is spread on the teacup T (work to be fed out), the operator turns back and moves the traveling machine body 2 backward. Will be done. Incidentally, in actual work, a processing unit dedicated to feeding is often provided at the rear of the traveling machine body 2 for forward work.

The clamp bolt 475 has an operation grip 475a at its upper end and a spacer 475b. The end of the clamp bolt 475 acts to press down the side edge of the elongated drawer hole 473 in the substrate portion 472. Thereby, the separation bearing unit 47 is positioned and fixed with respect to the opening / closing frame 372 of the take-out side roll support frame 371. The separation bearing 470 is fixed to a bearing mounting portion 476 that rises from the base plate portion 472. Opposing to the bearing mounting portion 476, the base plate portion 472 is somewhat raised and formed on the front side of the side, and an operation portion 477 serving as a clue for sliding the separation bearing 470 is formed.

Next, the covering material guide device 5 which is a main configuration of the collection guide mechanism for the covering material S will be described.
As shown in FIGS. 2, 3, 4, 5, and 9, the covering material guide device 5 has the front side to be wound as the front or the front with respect to the direction in which the covering material S is wound. If the side to be taken is the rear stage or the rear side, it is provided at the front stage of the winding shaft 40. The covering material guide device 5 includes a receiving guide body 51, an intermediate guide body 52, and a winding guide body 53 as main members, and the intermediate guide body 52 and the winding guide body 53 are further separated by a rotating bracket 54. It is supported so that the installation posture can be reversed as a whole.
First, the receiving guide body 51 will be described. The receiving guide body 51 is provided with plate-like members 510 which are appropriately fitted and fitted at both ends, and is attached to the distal end portion 393 of the extension frame 39 so that the set angle can be adjusted somewhat. The receiving guide body 51 is formed by bending a pipe-shaped member, the bending direction of the receiving guide body 51 in a plan view, and the center portion being bent toward the rear. This configuration gives the tendency that the covering material S to be scooped up by the receiving guide body 51 is concentrated toward the center of the covering material guide device 5, and is set as the centripetal guide structure 511.
Incidentally, the centripetal guide structure 511 itself can be configured to be guided around the covering material S by an appropriate method such as applying a drum-shaped roller in addition to being curved in this way. As such a variation, one disclosed by Japanese Patent Application No. 2013-102668 developed by one of the present applicants and extending to a patent application can be applied. The receiving guide body 51 is configured to be folded at the distal end portion 393 of the extension frame 39 by a folding link portion 392 so that the receiving guide body 51 can be folded up in the upward direction. It is configured so as not to hinder the transportation of 1 on a truck or the like.

Next, the intermediate guide body 52 and the winding guide body 53 will be described.
The intermediate guide body 52 is a rotatable roller having a straight guide surface, and is provided rearward with respect to the receiving guide body 51 in the feeding direction of the covering material S in a side view as described above. It has been.
Further, a winding guide body 53 is provided at the subsequent stage of the intermediate guide body 52. In addition, the meaning of this latter stage means that it becomes the next process when viewed in the feeding direction of the covering material S, and does not mean that it is positioned rearward. When actually viewed in terms of position, in the winding operation state in which the covering material S is being wound, the winding guide body 53 is positioned slightly forward and slightly above the intermediate guide body 52 in a side view. The winding guide body 53 is formed by bending a circular tubular member, and the curved central portion takes a shape that projects forward. Such a shape is a configuration for guiding the covering material S guided here so as to spread outward from the central portion, and this is referred to as a deployment guide structure 531. The unfolding guide structure 531 can select, for example, a drum-shaped roller shape with a middle swelling, similarly to the centripetal guide structure 511 in the receiving guide body 51. The take-up guide body 53 is provided with a straight tubular reinforcing bar 532 substantially parallel to the take-up shaft 40. The take-up guide body 53 with the reinforcing bar 532 is connected to the end connecting plate. 533 is integrated. The end connection plate 533 is connected to the rotation bracket 54 so as to be integrated.

The rotating bracket 54 includes a rotating shaft 541 in the middle of the vertical direction in the winding operation state. The rotation shaft 541 is supported by the rotation fulcrum 382 of the rotation support bracket 381 of the guide support post 38, and the rotation bracket 54 is rotatable with the intermediate guide body 52 and the winding guide body 53. Attached to.
The intermediate guide body 52 is supported below the rotating bracket 54 in the winding operation state. As an example, the intermediate guide body 52 is rotatably supported by the intermediate guide bearing 542.
Note that the handle-like member extending forward from the lower side of the rotating bracket 54 is an operation lever 543, which is a clue for rotating the rotating bracket 54 as will be described later.

Here, the reversing operation of the setting state of the intermediate guide body 52 and the winding guide body 53 by the turning operation of the turning bracket 54 will be described.
As shown in FIGS. 2 and 9, by operating the operation lever 543 in the rotating bracket 54, the setting is switched from the winding operation state of the intermediate guide body 52 and the winding guide body 53 to the “winding preparation state”. Become. That is, as shown in FIGS. 5C and 9, when the rotating bracket 54 rotates clockwise, the intermediate guide body 52 rotates so as to be positioned upward, while the take-up guide body 53 moves upward. It will be in a position that faces downward from.
At this time, the covering material S is passed between the intermediate guide body 52 that is positioned above and the winding guide body 53 that is positioned below the intermediate guide body 52, and the tip of the covering material S is When going to the winding shaft device 4 side, the passage route of the covering material S itself is set in a straight line, and the winding operation of the covering material S around the winding shaft 40 is very easy to perform.
On the other hand, when the rotating bracket 54 is rotated from this state, the intermediate guide body 52 is changed in position from the upper position to the lower position as shown in FIGS. 9B to 9E. The taking guide body 53 moves so as to return from the lower position to the upper position. As a result, the covering material S has a guide track in a zigzag winding operation state toward the receiving guide body 51, the intermediate guide body 52, the winding guide body 53, and further to the winding shaft device 4 in a side view. The

  Note that such a rotation bracket 54 has a lock mechanism shown in FIG. 5C in order to particularly reliably maintain the winding operation state. In other words, reference numeral 544 denotes a lock pin, which is slidably guided with respect to the lock pin bracket 544a attached to the rotating bracket 54, and always tends to protrude downward by the lock pin spring 544b. Set to have. A lock pin receiving hole 544c is formed in the extension frame base portion 391 of the extension frame 39 at the position of the tip of the lock pin spring 544b, and the tip of the lock pin 544 is inserted in a hook shape here, whereby the rotating bracket 54 Is maintained in the winding operation state.

The configuration of the farm management apparatus 1 to which the present invention is applied has the configuration as described above, and the operation mode thereof will be described below in accordance with the work order.
(i) Situation of the covering material S First, the situation where the covering material S such as a cold chiller is provided on the teacup T, which is an example of the work target, is described.
In this situation, as shown in FIG. 1 and FIG. 10, a cold koji that covers from the top surface of the teacup T to its side surface is applied. Especially when the covering material S is wound from the teacup T, There is a problem that the winding operation is difficult because there is a portion that is disposed so as to hang down from the bottom of T.

(ii) Setting of the farm management apparatus 1 Prior to the work, the following preparations are made for the farm management apparatus 1.
(ii-A) Attaching the skid member 29 As described above, the leg frame 21A of the traveling machine body 2 and the nearby auxiliary machinery and the like in the farm management device 1 and the branches of the teacup T are covered there. Since the interference with the covering material S is a hindrance to work, the skid member 29 is mounted to avoid this. When the skid member 29 is a cover sheet 291 that is flexible and has a certain stiffness, the hook receiving hole 291a provided in the cover sheet 291 is engaged with the skid fixing portion 210 of the traveling machine body 2 so that the skid member 29 is substantially suspended. It is attached or hung using a hook strap 291b as shown in FIG. Accordingly, the cover sheet 291 is attached in a state of being wound around the leg frame 21A.
In the case where the skid member 29 is a hard cowl 292, these are attached so as to surround the leg frame 21A in the middle, and the skid fixing portion 210 and the like are fixed by a fixing pin 293 while the pair of hard cowls 292 are being aligned. Use to fix.

(ii-B) Mounting of the covering material processing unit 3 The covering material processing unit 3 is attached so that the rod receiving sleeve 31 in the base frame 3A is inserted into the adapter rod 28B in the traveling machine body 2 in an almost assembled state. As an actual work, for the purpose of saving labor, the entire covering material processing unit 3 is supported on a movable stand or the like, the farm management device 1 is run in accordance with the position, and the adapter rod in the elevating adapter 28 is used. It takes the form of setting the height of 28B and inserting it there. In this fixing, the inserted state is maintained by an appropriate lock pin or the like according to a conventional method.
Further, the receiving guide body 51 of the covering material guide device 5 in the covering material processing unit 3 folds the folding link portion 392 in the middle of the extension frame 39 in the guide frame 36 at the time of transportation and the like, and the tip end portion 393 is moved upward. However, the position is set so that the receiving guide body 51 faces forward, with the tip 393 rotated downward.

(iii) Winding preparation
(iii-A) Setting to take-up preparation state In preparation for winding the coating material S, preparation for starting winding is performed in the conventional manner that the receiving guide body 51, the intermediate guide body 52, and the take-up guide body that were always in the winding work state The covering material S is passed in a zigzag manner between the winding member 53 and the leading end of the coating material S is fixed to the winding shaft 40 of the winding shaft device 4.
In the present invention, by setting the intermediate guide body 52 and the winding guide body 53 to the winding preparation state at the time of winding preparation, the setting is made such that the covering material S is passed in such a zigzag shape. It is no longer necessary. In other words, the winding preparation state is set to about 150 ° in the clockwise direction in the drawing by operating the operation lever 543 as shown in FIG. Rotate to reverse the setting of the intermediate guide body 52 and the winding guide body 53 in the vertical direction. Thereafter, the covering material S is passed almost linearly between the upper intermediate guide body 52 and the lower winding guide body 53, and the tip of the covering material S passes through the winding shaft 40 of the winding shaft device 4. Fix it. The covering material S is set on the take-up shaft 40 because the lock pin body 412 always protrudes from the take-up shaft 40, so that the mesh of a relatively cold mesh or the like is locked to this. Then, the main body shaft 41 is rotated several times, and the tip of the covering material S is appropriately wound around the body shaft 41 to be in a winding start state.

(iii-B) Setting to Winding Operation State After setting to this state, the rotating bracket 54 is operated again, and the operation lever 543 is shown in FIGS. 9 (b) to 9 (e). The intermediate guide body 52 is rotated counterclockwise so that the intermediate guide body 52 located above pushes the covering material S downward from above, while the winding guide body 53 located below is covered by the covering material S from below. Is further guided forward and upward of the intermediate guide body 52. As a result, the covering material S is guided in a zigzag manner between the receiving guide body 51, the intermediate guide body 52, the winding guide body 53, and the winding shaft 40 in a side view. This state is the “winding work state”.

(iv) Winding Work In this state, the farm management device 1 is advanced, and the winding shaft 40 of the winding shaft device 4 is driven to wind the covering material S there.
(iv-A) Centric guide structure 511 of the receiving guide body 51 (FIGS. 10A to 10C)
As described above, since the covering material S is provided so as to cover especially the skirt portion of the teacup T, this portion hinders smooth winding. First, the first important point that the receiving guide body 51 works satisfactorily is that the receiving guide body 51 guides the covering material S from below.
Further, the receiving guide body 51 has a shape in which the central portion is further curved backward in a plan view in the traveling direction, and this shape, that is, the centripetal guide structure 511 is centered on the covering material S to be wound. It works like a close-up.

(iv-B) Preliminary lateral development by the intermediate guide body 52 (FIG. 10D)
In such a state, the covering material S that reaches the intermediate guide body 52 is assisted by the fact that the intermediate guide body 52 is rotatable as an example. Guided to switch forward. Of course, the substantial action of guiding forward is because the winding guide body 53 is disposed forward and upward from the intermediate guide body 52.

(iv-C) Horizontal deployment guide by the winding guide 53 (FIG. 10 (e))
Since the winding guide body 53 has the unfolding guide structure 531, the coating material S that has reached the winding guide body 53 is guided in a curved shape facing forward in plan view and spreads sideways. , The fully expanded state appears over the entire width.
In this state, the winding shaft 40 in the winding shaft device 4 is driven, and the coating material S is wound around the winding shaft 40 to obtain the winding roll SR.
At this time, since the winding shaft 40 is provided with the flange 43, the side edge of the covering material S is smoothly guided by this.

(v) Action of skid member In the above-described winding operation of the covering material S, it is inevitable that the leg frame 21A in the farm management device 1 is in contact with the teacup T. At this time, due to the presence of the skid member 29, the leg frame 21A or the like does not come into direct contact with the tea tree skirt or the like, and the skid member 29 smoothly slidably contacts the teacup T or the covering material S covered thereon. It will be in such a state. As a result, the conventional interference between the leg frame 21A or its peripheral equipment and the teacup T or the covering material S can be completely prevented.
If attention is paid to the covering material S at this time, as described above, the operation of the centripetal guide structure 511 included in the receiving guide body 51 involved in the winding of the covering material S and the laterally expanded guide structure included in the winding guide body 53 are described. Thus, the covering material S is not wound up in a state of being offset from the teacup T.
This means that the covering material S is always in a certain position with respect to the leg frame 21A of the farm management device 1 moving between the teacups T. As a result, the covering material S is not removed from the position in contact with the skid member 29 and is smoothly wound. By the way, when the covering material S is wound up, if this is extremely shifted to one side with respect to the teacup T, the covering material S is positioned further below the skid member 29 on the offset side, The state of being caught in the crawler traveling body below the leg frame 21A is not unpredictable.

(vi) Removal of the wound coating material S When such work is completed, the work of removing the take-up roll SR from the take-up shaft 40 is performed.
In this operation, in this embodiment, the winding shaft 40 in the winding shaft device 4 is separable into a main body shaft 41 and a separation shaft 42, and the separation shaft 42 side is opened like a door by an opening / closing frame 372, for example. It is configured so that it can be removed from the installation position, and the work is easy to perform.
Hereinafter, these operations will be described.

(vi-A) Unraveling work First, the covering material S is fixed to the winding shaft 40 because the covering material S is locked to the locking pin main body 412 of the main body shaft 41. by.
The covering material S wound here is in a state where the locking pin main body 412 is pierced to some extent by the tension generated during the winding operation.
For this reason, first, the open / close flange 43B is manually rotated with a clue to rotate the winding shaft 40 in the direction opposite to the winding direction. As a result, the covering material S that has become the take-up roll SR is released from the strong biting with the locking pin main body 412 in the main body shaft 41 at the center thereof.

(vi-B) Separation of Winding Shaft 40 Following such work, an operation of separating the separating shaft 42 constituting the winding shaft 40 from the main body shaft 41 is performed. This operation is an operation of shifting the slide bracket 471 in the separation bearing unit 47 to the outside as shown in FIG. 5B. Specifically, the clamp bolt 475 in the slide bracket 471 is operated, and thereby the substrate. The fixed state of the portion 472 with respect to the open / close frame 372 is released. This operation can be performed without the need for a tool because the clamp bolt 475 has an operation grip 475a at its upper end.
Of course, it is not a structure for fixing or releasing the slide bracket 471 by the clamp bolt 475, and it does not matter if the operation is performed with a lock member called a quick release or quick snap as long as the purpose can be achieved. .

When the fixing by the clamp bolt 475 is released, the slide bracket 471 can freely move between the upper surface of the opening / closing frame 372, and the slide elongated bracket 473 is provided, whereby the slide bracket 471 is provided. 471 can be moved to the outside of the open / close frame 372. As a result, the entire separation bearing unit 47 moves, and the separation bearing 470 moves outward with the separation shaft 42. As a result, the separation shaft 42 comes out of the state of being fitted to the main body shaft 41 so that the main body shaft 41 and the separation shaft 42 are separated.
In setting the main body shaft 41 and the separation shaft 42 in the winding shaft 40 again, the rotation prevention protrusion 42a provided on the separation shaft 42 and the rotation prevention notch 416 in the main body shaft 41 are assembled and assembled. Become.

Thus, when the main body shaft 41 and the separation shaft 42 are separated from each other, the main body shaft 41 in the winding shaft 40 is free to be supported on the separation shaft 42 side, and the free end portion hangs down at that position. It becomes a state. In order to allow this state, the main body bearing 440 can be deflected in a three-dimensional direction by the action of the horizontal rotation board 441 and the vertical swing bracket 442, and the free end side of the main body shaft 41 is arranged. Sagging can be tolerated.
In such a state, the covering material S is extracted from the free end side of the main body shaft 41. Actually, however, if the separation shaft 42 exists at that position, the free end of the main body shaft 41 is sufficiently moved upward to avoid them. It must be pulled out in a state of facing, and workability is poor. For this reason, in this apparatus, after such separation of the separation shaft 42 is completed, they are further withdrawn from the position as a whole to facilitate the removal of the winding roll SR remaining on the main body shaft 41. It is what.
That is, as shown in FIG. 4D, the lock pin 375 of the guide frame 36 is released so that the open / close frame 372 is opened in a door shape with respect to the hinge column 373. Thus, if it is set as the state opened to the side, the separation bearing unit 47 supported by the opening-and-closing frame 372 will withdraw from the position as a whole. As a result, the portion where the separation bearing unit 47 and the opening / closing frame 372 are provided is opened sufficiently large, and the take-up roll SR can be pulled out from the main body shaft 41 while the main body shaft 41 remains substantially in that position.
Incidentally, the open state of the opening / closing frame 372 does not have to be such an opening door shape. It is only necessary to be able to move substantially from the steady position, and may be a form in which the lower edge is a hinge and the upper edge part is tilted toward the front side, a form in which it slides into the sliding door state and moves away. Note that the locking pin main body 412 in the locking pin unit 410 is configured such that the rotation direction of the locking pin main body 412 can fall in the extraction direction of the winding roll SR, so that the winding roll SR is pulled out. As shown in a partially enlarged view in FIG. 4 (d), the locking pin falls down in a state where it is pressed against the core of the take-up roll SR, and can be easily removed.

(vii) Preparation for the next process After such work, first, in the winding shaft device 4, the opening / closing frame 372 is closed again, so that the separation shaft 42 is returned to the original closed position, and then the cutting shaft 42 is cut. The separating shaft 42 is fitted into the free end side of the main body shaft 41. The operation is such that the slide bracket 471 of the separation bearing unit 47 is pushed in toward the main body shaft 41 and the push-in state is maintained by the clamp bolt 475. The open / close frame 372 as a whole is also maintained in an open / closed state by operating the lock pin 375.
On the other hand, in the covering material guide device 5, the position setting of the intermediate guide body 52 and the winding guide body 53 is reversed by operating the rotating bracket 54 to return it again from the winding work state. Take the winding ready state.

[Other embodiments]
The present invention is based on the embodiment described above as one basic technical idea, but the following modifications can be considered.
Although the present invention has been described mainly for tea gardens, it may be used in other farms as mentioned above. For example, it can be applied to the handling of mulching sheets.
Further, the coating material S is wound up by the winding shaft device 4. For example, as shown in FIG. 11, the coating material S is not formed in the form of the winding roll SR by the pinch roller 48. It can be stored in a zigzag shape while being guided back and forth. In this embodiment, the pinch roller 48 is substantially equivalent to the winding shaft 40, and is a constituent member of the winding shaft device described in the claims.
