Description

  The present invention relates to an apparatus for winding a covering material such as a cold koji directly on a teacup, for example, and a novel winding and unfolding apparatus capable of winding up efficiently and beautifully. It is related to.

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”.

  Various methods and apparatuses have been devised for covering such a covering material in a rolled-out state in a state where the covering material is unrolled or rolled up in 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 patent application, and has reached patent application (Patent Document 5).
In this prior invention, while moving along a covering object such as a teacup, the covering material covering the covering object in the unfolded state is taken up, while the covering material is unwound and unfolded on the covering object. A winding shaft for winding the coating material, and a plurality of guide bodies for peeling the coating material from the coating target and guiding the peeled coating material toward the winding shaft. It comprises a reeling machine frame that supports it. The tip guide body provided on the leading end side in the winding advance direction of the guide body is formed in a convex curved shape in a plan view in the advance direction, and is unfolded on the covering target at least during the winding operation. It is provided so as to receive the covering material that has been scooped up.
While this prior invention can be sufficiently evaluated in that the coating material can be smoothly wound under favorable conditions, the winding material is unbalanced under bad conditions where the coating material is beaten under strong winds. Further points to be solved have been found. In other words, once the covering material is shifted to either the left or right due to the strong wind or for some reason described above, the tendency of the covering material to shift is further promoted so as to be guided by the convex curved guide body, and as a result, the winding shaft In this case, the covering material does not become an average spread state and is wound up by being offset.

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

  The covering material winding and unfolding apparatus 1 (hereinafter abbreviated as the winding and unfolding apparatus 1) of the present invention is a traveling machine body that travels across a covering target T such as a teacup as shown in FIGS. 2 and a winding and unfolding machine body 3 supported by the traveling machine body 2 so as to be positioned on the upper surface of the coating target T. In other words, the winding and unfolding apparatus 1 shown in the present embodiment has a structure in which the winding and unfolding machine body 3 is mounted on the traveling machine body 2 that uses a riding-type teacup-running type tea garden management machine often used in a tea garden as an example. Is the basic structure. This is because it is intended that the worker can run the traveling machine body 2 and wind up the covering material S at the same time. Of course, in such a form, there is no need for an assistant who assists the smooth winding of the covering material S, and it is possible to reduce the labor and labor saving of the worker, and the expense is not required for the assistant. Can also be reduced. Furthermore, since the existing traveling machine body 2 is used, the winding and unfolding device 1 can be introduced at a low cost.

  Here, the “tea garden management machine” in the “tea bowl straddling type tea garden management machine” will be described. The “tea garden management machine” is an apparatus that attaches an appropriate tea garden management machine body to the traveling machine body 2 according to the work content and performs a desired work. Note that this type of tea plantation management machine includes a pruning machine that prunes branches and trunks to restore the tree structure, a plucking machine that plucks tea leaves, or sprays fertilizers, chemicals, etc. A fertilizer / controlling machine body is well known. In this embodiment, the winding and unfolding machine body 3 is applied as a tea garden management machine body.

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 winding and unfolding machine body 3 constituting the winding and unfolding 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 across the teacup T, and has a frame 21 that is formed in a gate shape when viewed from the running direction, that is, the longitudinal direction of the teacup T. The frame 21 includes left and right leg frames 21A provided in a standing state between the ribs, a connecting frame 21B that connects the left and right leg frames 21A, and an elevating bracket 21C that is attached to the leg frame 21A so as to be movable up and down. Consists of. Incidentally, for example, the picking machine body can be attached to the elevating bracket 21C. In this case, the picking machine body is provided at a substantially middle position (intermediate in the front-rear direction) of the traveling machine body 2.
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 take-up and deploying device 1 where an operator who rides on the take-up and deploying device 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 cockpit 23. As an example, a hydraulic pump (not shown) is driven by the motor 26 and supplied by the hydraulic pump. The traveling oil 22 is driven by hydraulic oil, the winding shaft 5 of the winding and unfolding machine body 3 to be described later is driven, and further, the cylinder (not shown) that drives the lifting bracket 21C is driven.

An adapter member for attaching the winding and unfolding machine body 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.

  Next, the winding deployment machine body 3 will be described. As described above, the winding and unfolding machine body 3 winds the coating material S such as a cold cocoon directly covered on the basket as the coating target T in a roll shape, but this machine body performs the unfolding operation, that is, the wound coating material S. This can also be applied to the case where the work is carried out and placed on the teacup T. For this reason, in the names of the present invention and the like, the terms “winding and unfolding apparatus”, “winding and unfolding machine body” and the like and “developing” are also used. In addition, even if the winding machine is not equipped with a deployment mechanism, that is, when the deployment work is performed manually or by another machine or a unit dedicated to deployment, the winding work is performed by the same method as the present invention. The winding and unfolding apparatus 1 (winding and unfolding machine body 3) of the present invention is included. Moreover, about the coating | coated material S, it is set as the winding roll SR as needed about the thing of the state wound up especially.

In this embodiment, as described above, since the winding and unfolding machine body 3 is attached to the traveling machine body 2, the mounting structure will be described first prior to detailed description of the winding and unfolding machine body 3.
The winding and unfolding machine body 3 is provided so as to be movable up and down with respect to the traveling machine body 2, and is attached so that the winding and unfolding machine body 3 is inserted into the adapter rod 28B as shown in FIGS. At this time, since the left and right adapter rods 28B can be independently set in height as described above, the winding and unfolding machine body 3 can be tilted in the left-right direction and mounted on the traveling machine body 2 as shown in FIG. The mounting method tilted in this way is effective when working in a teacup T on an inclined ground.
The winding and unfolding machine body 3 is attached to the front part of the traveling machine body 2 unlike the plucking machine body and the like, but this means that the traveling machine body 2 is moved forward, in other words, the operator is normally facing forward. This is because the winding work of the covering material S already developed on the teacup T can be performed. For this reason, in the operation | work which expand | deploys the coating | covering material S on the teacup T (work to draw out), it will carry out, retreating the traveling body 2 while the operator looks back.

Hereinafter, the winding and unfolding machine body 3 will be described in more detail.
First, the winding and unfolding machine body 3 is prepared as one of the so-called attachments for the traveling machine body 2 as a tea garden management machine as an example, and as shown in FIG. A configuration is adopted in which a frame 3B and a guide action frame 3C are provided and these are superposed and combined. The reason why the frame member is divided is to enable the winding and unfolding machine body 3 to be set at an appropriate position in accordance with the situation of the teacup T or the like. Therefore, when it is in an environment where the winding and unfolding machine body 3 can be operated in a certain posture from the situation of the teacup T, it is not necessary to adopt such a frame member configuration.

First, the base frame 3A will be described. The main member is a base frame 30 that is horizontally long in a plan view, and includes rod receiving sleeves 31 at positions close to the left and right sides of the lower surface side of the base frame 30. The rod receiving sleeve 31 is a member for receiving the adapter rod 28 </ b> B in the traveling machine body 2 and attaching it to the traveling machine body 2.
The rod receiving sleeve 31 has a variable width interval between the left and right rod receiving sleeves 31 so that even if the height of the adapter rod 28B is changed to the left and right, it can be accommodated. That is, one rod receiving sleeve 31 is a fixed side rod receiving sleeve 31A, and the other is a movable side rod receiving sleeve 31B, which is slidable in the left-right direction.
Specifically, two support rods 311 are provided as an example along the width direction of the teacup T with respect to the base frame 30, and a slide block 312 is attached to the support rod 311. A movable rod receiving sleeve 31B is provided. Further, a transverse shift motor 32 that is a drive member for transversely moving the intermediate transverse frame 3B supported by the base frame 3A to the left and right is mounted on the base frame 3A. In this device, a transverse shift motor 32 is mounted near the fixed rod receiving sleeve 31A, and the screw shaft 33 is rotationally driven via a relay chain 322 wound around its output shaft.
On the other hand, near the center of the base frame 30, there are provided transverse support rails 34 at four places on the left and right in the front-rear direction, and an upper presser plate 341 is provided above the support rails 34.

  Next, the intermediate transverse frame 3B will be described. The intermediate transverse frame 3B is supported so as to freely traverse the base frame 3A. First, the intermediate transverse frame 3B includes the intermediate transverse frame 35 as a main frame member, and has a rectangular configuration as a whole. Near the four corners of the intermediate transverse frame 35 are provided with wheels 351, and the wheels 351 are configured to roll on the transverse support rails 34 in the base frame 30. Further, a female screw block 352 is fixed to the lower surface of the intermediate transverse frame 35, which receives the screw shaft 33 on the base frame 3A side and constitutes a so-called ball screw mechanism. In addition, a guide action frame mounting plate 353 configured in a bracket shape is horizontally provided at a position close to the female screw block 352.

Next, the guide action frame will be described.
The guide action frame 3C is configured with a guide frame 36 that is elongated in the horizontal direction in plan view as a main frame member. A pair of left and right roll support posts 37 and guide support posts 38 are provided so as to rise from the guide frame 36, and a guide support arm 39 extends substantially horizontally so as to protrude forward from the front edge of the guide frame 36. .
A center mounting frame 361 is provided at the center of the guide frame 36 in the width direction. A pair of left and right deflection mounting frames 362 are provided at equal intervals across the center mounting frame 361, and the deflection mounting frame 362 includes a slightly curved elongated bolt hole 363. The guide frame 36 is covered with an upper surface guard panel 364 at the upper center. The guide frame 36 and the intermediate traversing frame 3B are attached in such a manner that the fixing bolt is passed through the central support portion 354 provided at the center of the intermediate traversing frame 35 in the center mounting frame 361 so that both are in a loose state. Connect to position. Further, a bolt is passed through the bolt hole 363 of the deflection mounting frame 362, and is fixed to the guide action frame mounting plate 353 in the intermediate traversing frame 3B. Since the bolt hole 363 is an arc-shaped long hole, the guide action frame 3C can be attached to the intermediate traversing frame 3B so that the attachment angle can be somewhat deflected in plan view.

Next, the material guide member 4 and the winding shaft 5 of the covering material S that are mainly attached to the guide action frame 3C will be described.
First, the receiving guide body 41 constituting the material guide member 4 is provided at the tip of the guide support arm 39, and the receiving guide body 41 is a bowl-shaped member that is concavely curved as an example in a plan view in the traveling direction. It is comprised by. The structure that is concavely curved in a plan view is the “centric guide structure (411)” in the claims. That is, the coating material S guided here is brought to the center.
Further, an intermediate guide body 42 is provided behind the receiving guide body, and is, for example, a single straight member. Of course, this member may be a bowl-like member to which a fixed pipe or the like is applied, or may have a roller-like configuration whose surface can rotate. The intermediate guide body 42 is attached below the guide support post 38.

Further, a winding guide body 43 is attached to the upper end of the guide support post 38, and this is constituted by a bowl-shaped member having a convex curve shape in plan view in the traveling direction. This structure having a convex curved shape in plan view is a “deployment guide structure (431)” in the claims. The centripetal guide structure 411 and the unfolding guide structure 431 can take other forms, which will be described later.
Next, the take-up shaft 5 has a configuration in which a take-up bearing 51 is provided at the upper end of the roll support post 37 and the shaft main body 52 is rotatably supported. The shaft body 52 has flanges 53 at both left and right ends thereof, and is configured so that the wound covering material S is accommodated therebetween. The shaft main body 52 is connected to a drive motor 54 to which a hydraulic motor is applied at one end thereof, and is rotationally driven.

About the structural member of the winding expansion | deployment apparatus 1 of the covering material of this invention, the form which was described above is taken and the operation | movement aspect is demonstrated.
[A] Winding operation (1) Situation of covering material S The covering material S covered on the covering target T such as the teacup T covers the top surface of the teacup T as shown in FIG. At the same time, there is some margin in the dimension in the width direction, and both edges in the left and right width direction are in a state of hanging from the end of the heel. This hanging portion is fixed to a tea tree stalk or the like with a clip or the like or tied with a string or the like to maintain the covering period of the teacup T or the shielding of solar radiation for the management period necessary for the tea leaves. In winding, the presence of this sag portion makes it difficult to wind smoothly.

(2) Preparation of apparatus As preparation for winding up such a covering material S, the following preparation is made about the covering material winding and unfolding apparatus 1. First, the winding shaft 5 for winding the coating material S is attached to the roll support post 37. At this time, the flange 53 is detachable with respect to the shaft body 52 of the winding shaft 5 in many cases. Therefore, the flange 53 is attached to the shaft body 52 before the winding shaft 5 is attached. .
One end of the shaft body 52 is connected to the drive motor 54 side by an appropriate coupler. On the other hand, the winding guide body 43 is fixed to the upper end of the guide support post 38 at the position closest to the winding shaft 5. In this fixing, there is some adjustment angle of the mounting angle, and an optimum angle is set empirically. In any case, the winding guide body 43 is formed in a convex curved shape toward the front so that the unfolding guide structure 431 is formed in a plan view. A straight rod-shaped intermediate guide body 42 is provided below and a receiving guide body 41 is attached to the tip of the guide support arm 39. This can also be adjusted empirically to an appropriate angle, orientation, etc., depending on the work site or the tailoring state of the tea tree or teacup. The receiving guide body 41 is also attached so as to form a centripetal guide structure 411 that is concavely curved forward in plan view.

(3) Preparation for winding The winding and unfolding machine body 3 is in such a state and the covering material S near the end of the teacup T is lifted. It is made to advance slightly in T and guides it above the receiving guide body 41 of the covering material S. In other words, when viewed from the receiving guide body 41, this is arranged so as to scoop the covering material S developed on the teacup T from the lower surface side. In addition, the position where the receiving guide body 41 scoops the covering material S first is the both ends in the width direction as shown in FIG.
Further, the end portion of the covering material S guides it below the intermediate guide body 42, changes the direction from there to substantially upward at right angles, and further passes from the front surface of the winding guide body 43 toward the upper surface. After that, the end is fixed to the winding shaft 5.

(4) Winding Work After passing through such a preparation stage, the traveling machine body 2 is advanced into the teacup T and the driving motor 54 is driven to wind up the covering material S. At this time, the coating material S wound around the winding shaft 5 has a larger winding diameter as the work proceeds. Therefore, if the rotational speed of the winding shaft 5 is constant, the peripheral speed increases, so that a smooth operation cannot always be performed. For this reason, it is preferable to adjust so as to decrease the rotational speed as the winding diameter increases so that an appropriate winding state can be obtained.

(5) Orientation guide In such work, the operation of the receiving guide body 41, the intermediate guide body 42, the winding guide body 43 and the winding shaft 5 will be described.
For example, under the influence of wind or the like during the work, there is a case where the wind enters the lower surface of the covering material S that has been partially scooped up and moves in such a way that it deviates from the bowl T. In such a case, conventionally, the state in which the covering material S spreads on the entire winding width of the winding shaft 5 on average collapses all at once, and manual correction is required each time. On the other hand, since the receiving guide body 41 of the present invention has the centripetal guide structure 411 having a concave curved shape toward the winding operation progressing direction, the coating material S when scooped up is shown in FIG. As shown in Fig. 1, the behavior is once collected at the center in the width direction of the apparatus. Such a behavior itself is not a preferable state when it is wound as it is, and it may become a spindle shape in which the coating material S is concentrated and wound around the center of the winding shaft 5. is expected. However, when the covering material S is guided to the center of the receiving guide body 41 as described above, the winding center of the covering material S is forcibly set to substantially the center of the winding and unfolding machine body 3 prior to final winding. It means to contribute to the smooth winding after that.

(6) Preliminary lateral development guide by the intermediate guide body The covering material S wound up in such a state is somewhat laterally displaced from the center due to the presence of the intermediate guide body 42 as shown in FIG. 5 (d). It is guided to expand and spread. Furthermore, after that, the transfer direction of the covering material S is switched, and as an example, the coating material S is guided toward the upper winding guide body 43.

(7) Lateral deployment guide by the winding guide body The winding guide body 43 receives the somewhat expanded coating material S and further guides it laterally so as to cover the entire width of the winding shaft 5. To do. This effect is achieved by providing the winding guide body 43 with a deployment guide structure 431 that is convexly curved in a plan view toward the winding work progressing direction. That is, the coating material S that has reached the winding guide body 43 is guided by the unfolding guide structure 431 so as to spread on both sides thereof, and is finally wound in a state in which the covering material S has spread sufficiently horizontally with respect to the winding shaft 5. Made.

(8) Completion of winding operation When the winding operation is performed in such a state, the winding shaft 5 is removed and stored separately, and the new winding shaft 5 is supported on the roll support post 37, and the next coating is performed. The material S is wound up.

[B] Unfolding operation The present invention exerts an extremely effective action mainly in the winding operation of the covering material S, but it can of course be used for unfolding operations. At this time, the receiving guide body 41, which is one of the important components of the present invention, can be removed and used. In deployment, the covering material S is already wound around the winding shaft 5 for deployment, and at least the receiving guide body 41 and the intermediate guide body 42 are allowed to pass through, and the end portion of the bowl T Fix it to the deployment start end.
In this state, the traveling machine body 2 moves while retreating between the teacups T, and is unfolded while appropriately feeding the coating material S from the winding shaft 5. With this development, when fixing both ends in the width direction of the covering material S to both ends of the teacup T, an auxiliary worker may follow the covering material S that is being developed separately, The worker who has performed the unfolding work may do it later.

[Other Embodiments]
The present invention is based on the embodiment described above as one basic technical idea, but the following modifications can be considered.
First, the center guide structure 411 in the receiving guide body 41 and the unfolding guide structure 431 in the winding guide body 43 can have appropriate forms.
That is, with respect to the receiving guide body 41, it is important to concentrate the covering material S toward the center in the width direction, and the centripetal guide structure 411 for that purpose is as shown in FIGS. 8B and 8C. The guide body 41 is divided as a rotatable roll body, and a large number of spike-shaped center guide bodies 410 arranged in a spiral shape having directionality in the guide action are provided around the guide body 41 so that the center guide structure 411 is provided. Can be configured. Of course, in this case, the receiving guide body 41 may be a straight bar-shaped rotating roll as long as the covering material S can be guided sufficiently toward the center due to the arrangement specification of the spike-shaped centroid guide bodies 410.
Alternatively, as shown in FIG. 7, it is possible to form a roller-shaped receiving guide body 41 having a drum-like central portion with a small diameter.

  As for the winding guide body 43, the unfolding guide structure 431 is constituted by spike-like spirally arranged pins as shown in FIGS. 8B and 8C, or shown in FIG. 8A. It is good also as a structure by which the coating | coated material S guided to this by such a spindle-type roller carries out the effect | action which spreads to the full width direction.

[Inclination setting]
Further, in the previous winding and unfolding work or the like, although the slope is not mentioned, the winding and unfolding machine body 3 travels by setting the height by changing the elevating adapter 28 that supports the winding and unfolding machine body 3 to the left and right. A state of being inclined relative to the airframe 2 is obtained, and a favorable setting suitable for the working conditions can be achieved even on an inclined ground.
That is, the rod receiving sleeve 31 of the base frame 3 </ b> A is fitted into the adapter rod 28 </ b> B of the elevating adapter 28, and the winding and unfolding machine body 3 is attached to the traveling machine body 2 in an attachment shape. Since one of the rod receiving sleeves 31 is the movable rod receiving sleeve 31B, even if the height of the adapter rod 28B is different between the left and right, even if the substantial width of both is changed, the movable rod The receiving sleeve 31B moves corresponding to at least a change in its length, and the inclined state of the winding and unfolding machine body 3 can be maintained as a whole.

(Movement in the width direction)
Furthermore, the guide action frame 3C on which the substantial action member in the winding and unfolding machine body 3 is mounted may be displaced from an appropriate position in the width direction of the teacup T, for example, when tilted. In this case, by operating the transverse shift motor 32 in the base frame 30, the screw shaft 33 can be rotated, and the winding and unfolding machine body 3 can be set at a preferred position with respect to the teacup T or the like. In other words, the intermediate traverse frame 3B is moved to the left and right as a whole by mutual threading of the female thread block 352 and the screw shaft 33 in the intermediate traverse frame 3B. As a result, the material guide member 4 and the take-up shaft 5 that substantially act as guides are moved. The apparatus is set to an appropriate winding state by shifting the installed guide action frame 3C to the left and right.
In the embodiment described above, the most realistic riding-type tea garden management machine is applied as the traveling machine body 2, but the covering material winding and unfolding device 1 is suitably hand-held frame as shown in FIG. 9. As the traveling machine body 2, it is possible to adopt a configuration in which the traveling machine body 2 is mounted, or a configuration in which a simple driving engine is mounted thereon.

[Form in which winding and unfolding are individually dedicated units]
As mentioned above in part in the embodiment described above, when the covering material S is handled, the apparatus of the present invention can be used at the time of winding, and a dedicated developing apparatus can be used at the time of expansion.
Incidentally, at the time of deployment, a winding roll SR of the covering material S is attached to the traveling machine body 2, and a unit dedicated for deployment is configured by combining appropriate guide rolls and guide bars, and the covering material winding and unfolding device 1 of the present invention is provided. It is used together with or replaced with this. This is shown skeletally in FIG. 10, and the deployment-dedicated machine body 6 has the coating material S wound around the core shaft 60 and a guide member 61 using an appropriate roll or bar on the deployment direction side. Is provided.
10 (a) and 10 (b) show a deployment-dedicated machine body 6 installed in front of the traveling machine body 2 in place of the winding and unfolding machine body 3 of the present invention. FIG. 10A shows that the covering material S is unrolled and unfolded in front of the traveling machine body 2, and the operation is performed while the traveling machine body 2 is moved backward.
On the other hand, what is shown in FIG. 10 (b) is one in which the unfolding direction of the covering material S is extended to the rear of the traveling machine body 2, and can be performed while the traveling machine body 2 is advanced.
Furthermore, what is shown in FIG. 10 (c) is configured such that the deployment-dedicated machine body 6 is disposed behind the traveling machine body 2 and is provided with the winding and unfolding machine body 3 of the present invention disposed in front. Of course, when only the unfolding operation of the covering material S is targeted, only the unfolding exclusive body 6 can be arranged behind the traveling body 2. When the deployment-dedicated machine body 6 is arranged behind the traveling machine body 2, it is naturally preferable that the feeding direction of the covering material S is the rear of the traveling machine body 2, so that the operator can move the traveling machine body 2 forward. However, it is possible to perform deployment work in a natural working posture.
