DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-film peeling apparatus for peeling and winding a multi-film covering a ridge.

[0002]

2. Description of the Related Art Japanese Patent Publication No. 7-55104 discloses a multi-film peeling apparatus for peeling a multi-film from a ridge covered with the multi-film and winding the multi-film. The peeling device described in this publication is provided with a winding device for winding a multi-film on a cart with a handle gripped by an operator, and a driving device for rotating and driving the winding device. When the multi-film is wound by the device, the carriage is pulled and moved forward by the tension applied to the multi-film.

[0003]

This multi-film peeling device is a dedicated machine which does not require any other working machine such as a tractor (previously, it was all installed as an accessory device of a tractor or the like). It is advantageous in that it can be manufactured at low cost and does not require a driving device for traveling because it is pulled forward by the tension applied to the multi-film at the time of winding and advances. However, this multi-film peeling device has the inconvenience that an operator needs to walk with the handle always holding the peeling device. In addition, if the multi-film is thickly covered with soil or the soil is hardened, a large force is required to peel off the multi-film, and the tension applied to the multi-film increases, and the multi-film is cut during winding. There was a problem.

In order to solve this problem, the present applicant has proposed FIG.
A multi-film peeling device shown in FIG. 11 was invented and filed earlier (Japanese Patent Application No. 11-298898). This device will be described below. The multi-film peeling device shown in FIGS. 8 and 9 includes a pair of front wheels 1, 1 and a rear wheel 2,
2, a carriage 3 running independently on a ridge covered with a multi-film, a winding device 4 for a multi-film F installed on the rear side of the carriage 3, an engine 5 for rotating the winding device 4, and an engine 5. A power transmission mechanism 6 for transmitting the driving force to the winding device 4, a guide roller 7 installed above the front side of the winding device 4, and a swing that reciprocates the guide roller 7 up and down by the driving force of the engine 4. Mechanism 8, guide roller 7
And a stopping device 9 installed in front of the vehicle.

The power transmission mechanism 6 comprises a speed reducer 11, a sprocket 12, a chain 13, and a sprocket 14.
The driving force of the engine 5 is transmitted to a main shaft 27 of the winding device 4 described below. The oscillating mechanism 8 uses the engine 5 to drive the speed reducer 1
, Driven by the crank mechanism 15, the transmission rod 1
6, a swing shaft 19 having both ends pivotally supported by bearings 18 fixed to a pair of brackets 17; a plate member fixed to the vicinity of both ends of the swing shaft 19 and having both ends of the guide roller 7 pivotally supported at the tip end; The upper end 16a of the transmission rod 16 is pivotally supported by a rear extension of one of the plate members 21a, and the rotation of the crank mechanism 15 causes the transmission rod 16 to move up and down, so that the plate member 21a (and 21b ) Swings about a swing shaft 19 (bearing 18), and the guide roller 7 likewise swings up and down. Note that the guide roller 7 is desirably located immediately above the axis of the rear wheel 2 or near the front side thereof. This is to reduce the load applied to the front wheels 1 to make the truck 3 easily move forward. According to the experiment in the field, the angle (θ) between the straight line passing through the axis of the rear wheel 2 and the guide roller 7 and the vertical line passing through the axis of the rear wheel 2 is about 15 degrees forward. In this case, the bogie 3 moved forward without relatively slipping of the front wheel 1. Therefore, this is a guide for the installation position of the guide roller 7.

The stopping device 9 is pivotally supported by a pair of brackets 22 on the carriage 3 so as to be rotatable, respectively, and is horizontally and rotatably supported at the upper end of the pivoting arm 23. And a transmission wire 25 attached to the lower end of the swing arm 23. The transmission wire 25 is normally in the position shown in the figure by the urging force of a spring (not shown), and the swing arm 23 is upright.
When the swing arm 23 is inclined backward (swings clockwise in FIG. 1) by applying a backward load to the transmission wire 2, the transmission wire 2
5 is pulled forward against the urging force of the spring, and this acts on an accelerator lever (not shown) of the engine 5 to return to the low rotation side, thereby stopping the rotation of the winding device 4.

Accordingly, the multi-film F is not easily peeled off, while the winding is performed continuously, the carriage 3 moves forward, and the lifting angle (δ) of the multi-film F gradually increases (= the multi-film F descends). In such a case, the detection roller 24 is pushed backward by the multi-film F,
The swing arm 23 is tilted backward, the engine 5 is rotated at a low speed via the transmission wire 25, and the rotation of the winding device 4 is stopped. Therefore, the tension applied to the multi-film F does not increase any more and cutting is prevented. Is done. When the rotation of the winding device 4 is stopped, the multi-film F may be manually peeled to some extent, and the winding by the present device may be started again.

The take-up device 4 is installed on the rear side of the guide roller 7, and as shown in FIGS. 10 and 11, the main shaft 2 whose one end is supported by a bearing 26 fixed at a predetermined position on the carriage 3.
7. A plurality of winding rollers (six in this example) are arranged around the main shaft 27 in parallel with the main shaft 27 to constitute a winding shaft, and are detachably fitted to the other end of the main shaft 27. A boss member 29, a retaining member 31 for screwing and fixing the boss member 29 to the main shaft 27, a bearing 32 detachably fitted to the outer periphery of the boss member 29 and rotatably supporting the boss member 29, and the like. A flange plate 33, a flange ring 34 and a contact plate 35 are integrally attached to one end of the main shaft 27, and a flange plate 36, a flange ring 37 and a contact plate 38 are also integrally formed on the outer periphery of the boss member 29. Rollers 39 corresponding to the respective winding shaft constituent members 28 are further mounted inside the flange plate 36.

The take-up shaft member 28 is provided on a bracket 41 attached to the outer periphery of the main shaft 27 with links 42, 4 respectively.
2 (forming a so-called parallel link mechanism) through the main shaft 2 while maintaining a parallel state with respect to the main shaft 27.
7 or a predetermined distance. In a no-load state, each winding shaft component member 28 is urged by a spring 43 and separates from the main shaft 27 as shown in FIG. 3, and one end of the winding shaft member 28 passes through a hole 33 a formed in the flange plate 33 to be brought into contact with the contact plate 35. The contact is performed and the positioning is performed. At this time, the parallel links 42 are not perpendicular to the main shaft 27,
It is slightly inclined to the boss member 29 side. The bearing 32 is rotatably mounted via a pair of pins 46 on a frame 45 supported swingably on the trolley 3 about the support portion 44. The bearing 32 swings about the support portion 44 when it is fitted to or removed from the boss member 29, but it is always rotatably mounted via the pin 46 so that the bearing 32 can always be kept parallel to the boss member 29. It does not hinder attachment and detachment.

At the time of winding the multi-film, the boss member 29 is fitted from the other end of the main shaft 27 with one end of each winding shaft constituting member 28 being in contact with the contact plate 35 as described above. Then, the other end of each winding shaft component member 28 slides on the corresponding roller 39, passes through a hole 36a formed in the flange plate 36, and comes into contact with the contact plate 38. Next, the frame 45 is raised, and the bearing 32 is attached to the boss member 29 from the outside.
To the other end of the main shaft 27.
1 is screwed in with the handle 47 to fix the boss member 29 to the main shaft 27 and, at the same time, to hold the bearing 32 at the above-mentioned fitting position. Thus, the main shaft 27 has one end rotatably supported by the bearing 26 and the other end rotatably supported by the bearing 32 together with the boss member 29. Also,
Both ends of the take-up shaft member 28 are supported by contact plates 35 and 38 at both ends to maintain their positions, and the inside (main shaft side) is supported by rollers 39. This is the take-up shaft (multi-film take-up Rotating shaft).

At the time of winding the multi-film, the carriage 3 is placed over a ridge covered with the multi-film, and the end of the multi-film is first manually peeled off, passed through the guide roller 7 and passed through the winding shaft constituting member 28. And the driving force of the engine 5 is transmitted to the winding device. When the main shaft 27 rotates to start winding the multi-film F, the multi-film F is peeled off from the ridges at the same time as the soil attached thereto is dropped by the tension applied to the multi-film F and the swinging operation by the guide roller 7. On the other hand, the trolley 3 is pulled forward by the tension applied to the multi-film F and automatically advances, and during this time, the operator does not need to stick.

If there is a part where the multi-film F cannot be peeled off smoothly, the winding is continued at that time, so that only the carriage 3 advances, and the inclination angle δ of the multi-film F is increased. Becomes larger. As the inclination angle δ increases, the component of the force acting on the peeling increases even with the same tension.
May be torn again. In this case, the inclination angle δ returns to its original state, but if the multi-film F is not peeled off, the inclination angle δ gradually increases (the multi-film F descends), and finally the multi-film F moves the detection roller 24 backward. By pushing, the swing arm 23 swings backward. Thereby, the accelerator lever of the engine 5 is pulled back to the low rotation range, the rotation of the winding device 4 is stopped, and the advance of the bogie 3 is also stopped. Note that the inclination angle δ
Becomes too large, the load applied to the front wheel 1 becomes large, the carriage 3 becomes difficult to move forward, and the tension applied to the multi-film F becomes large, so that the multi-film F is easily cut. Is prevented. When the bogie 3 stops, the operator may operate the device again, for example, by removing hard soil.

When the winding of the multi-film F is completed,
By turning the handle 47, the retaining member 31 is removed from the main shaft 27, the frame 44 is tilted outward, the bearing 32 is removed from the boss member 29, and the boss member 29 is further removed from the main shaft 27. Next, the parallel link mechanism is tilted down to reduce the diameter of the take-up shaft constituted by the respective take-up shaft constituent members 28, and the multi-film wound multiple times around the take-up shaft is extracted. Although the multi-film is wound around the winding shaft component member 28 in multiple layers and strongly compressed in the diameter reducing direction, the diameter of the winding shaft is reduced, so that the multi-film can be easily removed.

In the multi-film peeling apparatus described above, the carriage basically travels over a ridge covered with the multi-film, and peels off the multi-film in a straight line. Depending on the conditions described above, it may be possible to smoothly peel off diagonally. Therefore, the present invention enables the multi-film to be peeled off as needed.

[0015]

According to the present invention, a winding device for horizontally winding a multi-film and a driving device for rotating and driving the winding device are installed on a carriage having front and rear wheels and running independently. In the multi-film peeling device, the winding device is rotatable within a predetermined range in a horizontal plane around a rotation fulcrum set on the carriage, and can be fixed at a predetermined position. I do. In the stripping device according to the present invention, the upstream side of the movement of the multi-film wound by the winding device is defined as the front side, and the downstream side is defined as the rear side. In addition, the self-sustained traveling means that the vehicle can stand on its own wheel and travel without being supported manually (in the stripping device described in the above publication, the operator supports the vehicle with a handle).
Means that.

In the stripping device, the winding device and the driving device are mounted on a turntable mounted on a carriage, and the turntable is rotatable around the turning fulcrum and fixed at an appropriate position. It may be as follows. In this case, for example, an arc-shaped guide rail centering on the rotation fulcrum is installed on the trolley, and the support member installed on the rotation table is movable along the guide rail. As the support member, for example, a roller or a slide member running on a guide rail can be used.

In the above-mentioned stripping apparatus, FIGS.
It is desirable to provide a guide roller on which a multi-film is hung in the same manner as in the peeling device of the prior application described in (1), and wind the multi-film on a winding device via the guide roller. Similarly, it is desirable that the guide roller is reciprocated up and down by the driving device. Reciprocating the guide roller involves shaking the multi-film with strength and weakness, just as when manually pulling the multi-film off the ground surface. It is easy to peel off from the surface of the ground and can remove attached soil. This guide roller is
It is installed on a turntable above the front side of the winding device.

As in the case of the peeling device of the prior application shown in FIGS. 8 and 9, when the angle at which the multi-film is lifted during winding is larger than a normal value, the winding is stopped. It is desirable to install a stop device. In this case, since the multi-film is lowered from the normal position on the front side of the cart, the same is true even if the multi-film is detected. This stopping device includes, for example, a swing arm that is erected so as to be able to swing and rotate toward the rear of the vehicle body and a horizontal detecting member attached to an upper part thereof, and the detecting member is pushed by a multi-film and When the swing arm swings backward by a predetermined angle, the lifting angle is detected. For example, a horizontally supported roller may be used as the detection member. The stop device is installed on a turntable in front of the guide roller. Further, a guide rod projecting to an adjacent ridge can be provided on the front side of the bogie.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a multi-film peeling device according to the present invention; FIG. It should be noted that the same numbers are given to portions having substantially the same structure, function, and the like as those of the stripping device shown in FIGS. 8 to 11, and detailed description is omitted.

The peeling device shown in FIGS. 1 to 4 has a pair of front wheels 1, 1 and rear wheels 2, 2, and a carriage 3, which runs independently.
A winding device 4 for the multi-film F installed on the rear side of the cart 3, an engine 5 for rotating and driving the winding device 4, a power transmission mechanism 6 for transmitting a driving force of the engine 5 to the winding device 4, a winding device. The guide roller 7 includes a guide roller 7 installed above the front side of the guide roller 4, a swinging mechanism 8 that reciprocates the guide roller 7 up and down by the driving force of the engine 4, and a stop device 9 installed on the front side of the guide roller 7. . A turntable 51 is installed on the trolley 3, and a support frame 52 that supports the engine 5, the power transmission mechanism 6, and the like is installed on the turntable 51.
The winding device 4, the engine 5, the power transmission mechanism 6, the guide roller 7, the swing mechanism 8, the stop device 9, and the like are mounted on the turntable 51.

As shown in FIG.
A boss 53 is attached to the rear center of the bogie 3, and the boss 53 is provided at the center of the rear end of the bogie 3.
To be rotatable. A support roller 55 is attached to a lower portion on the front side of the turntable 51, and an arc-shaped guide rail 56 centering on a rotation fulcrum shaft 54 is installed on the carriage 3 below the support roller 55. Is allowed to run on it. As a result, the turning table 51 is turned
And is supported on the carriage 3 by the support rollers 55. A regulating body 57 is horizontally supported below the rotating table 51 and is constantly urged toward a guide rail 56 by a spring 58 so that its head 57 a
Can be freely inserted into horizontal locking holes 59 formed at several places (five places).

In addition, the rear handle 60 is connected to the turntable 51.
At the rear end, a front handle 61 is installed on a front frame 62 attached to the front end of the bogie 3. Further, a wheel support frame 64 having a hollow cross section is installed horizontally and horizontally on the trolley 3, and a horizontal support arm 63 of each wheel is inserted into the wheel support frame 64, and a vertical support arm 65 of each wheel is attached to both ends of the horizontal support arm 63. ing. Vertical support arm 65
Consists of a frame section 66 having a hollow section fixed to the horizontal support arm 64, and an arm section 67 inserted therein,
The axle of each wheel is fixed to the arm portion 67. Each horizontal support arm 64 is slidable with respect to the wheel support frame 63, and each arm 67 is slidable with respect to each frame 66, and can be fixed at an appropriate position. Therefore, the distance between the front wheels 1 and 1 and the distance between the rear wheels 2 and 2 or the height of the vehicle body can be adjusted as appropriate, and furthermore, each wheel is adjusted by expanding and contracting in the horizontal or vertical direction. The adjustment can be done smoothly.

When winding the multi-film, the regulating body 57 is pulled forward against the urging force of the spring 58 (FIG. 4).
Imaginary line), the head portion 57a is pulled out from the locking hole 59, and the turntable 51 is turned in a horizontal plane about the turning fulcrum shaft 54 in the desired direction (the direction of the other locking holes 59). Turn. During this time, the support roller 55 runs on the guide rail 56. The turntable 51 is stopped in a desired direction, the head portion 57a is fitted into the stop hole 59 at the stop position again, and the turntable 51 is fixed to the guide rail 56. 1 and 2
As shown in, when turning table 51 is directed straight forward,
This stripping device is substantially the same as that of FIGS. The stripping device travels across the ridges 49 covered with the multi-film F, peels the multi-film F in a straight line, and removes the upper frame 68 (multi-film F).
), And through the guide roller 7.

On the other hand, as shown in FIG. 5, when the turntable 51 is directed obliquely, the multi-film F of the adjacent ridge 49a is formed.
Can be stripped diagonally. By doing so, the stripping line 69 becomes oblique, and the multi-film F
9a, the soil and grass on the peeled multi-film F easily flow sideways, and the winding resistance is reduced, and the breakage of the multi-film can be prevented.

In each of the above-described examples, the front side of the stripping device is directed toward the laying of the multi-film F, and the stripping device is moved forward with the winding. The rear side of the apparatus can be oriented in the direction of the laying of the multi-film, and the peeling device can be wound back while being retracted with the winding. FIG. 6 shows that the rotating table 51 is directed straight forward, the peeling device is advanced backward on the multi-film F, the multi-film F is folded back on the front side of the peeling device, and the leading end is wound via the guide roller 7. It is wound around a winding shaft of the take-up device 4 and wound up. As the number of revolutions of the engine 5 is increased to start winding, the operator holds the rear handle 60 and pulls the peeling device backward.

When the peeling device is advanced to peel off the multi-film F in a straight line, there is an advantage that the carriage 3 automatically advances due to the tension applied to the wound multi-film F. However, the wind engulfed it, and it was peeled off from the ridges and was greatly lifted, sometimes breaking. However, in the method shown in FIG. 6, since the multi-film is stepped on by the operator and the wheel of the peeling device, the multi-film is not greatly swollen and does not break even in a strong wind.

The peeling device shown in FIG. 7 is different from the peeling device shown in FIGS. 1 to 6 in that a guide rod 70 projecting from an adjacent ridge is provided on the front side of the bogie 3. Is the same. The guide rod 70 is attached to the front frame 62 and is located at a position slightly higher than the front wheel 1 in front of the front wheel 1.
It can project to either the left or right side, and has elasticity as indicated by the imaginary line.

The rotary table 51 of the peeling device is fixed obliquely so that the multi-film F on the adjacent ridge 49a is pulled obliquely while retreating. In this case, it is just like combining the methods of FIGS. 5 and 6,
While winding the multi-film F with the winding device 4, the operator pushes the cart 3 backward with the front handle 62, and peels the multi-film F from the ridge 49a. At this time, since the folded portion 71 of the multi-film F is formed diagonally in front of the stripping device, the multi-film F
Is easily peeled off from the ridges 49a, and soil, grass and the like on the peeled multi-film F easily flow sideways, thereby reducing winding resistance and preventing breakage of the multi-film. Also, the multi-film will not be greatly overheated even in a strong wind.

Here, if there is no guide rod 70, when there is a strong follow-up wind (wind from the front to the rear of the stripping device), the multi-film F is bent toward the body by blowing the wind, and When the guide rod 70 is present, the multi-film F blown toward the fuselage is received by the guide rod 70, and is wound via the guide roller 7 without being entangled with the fuselage. It is wound by the take-up device 4. Further, since the multi-film F is once received by the guide rod 70, the multi-film F can be uniformly wound without being offset to one side. In addition, the guide bar 70 has a function of a scraper for removing soil and the like attached to the peeled multi-film. In particular, when the elasticity is high, the effect is increased. Also acts as a tension to absorb the slack of the multi-film.

Although the retreating system is illustrated in FIG. 7, the stripping device provided with the guide bar 70 can be applied to a forward system as shown in FIG.

[0031]

The multi-film peeling apparatus according to the present invention can run over a ridge covered with the multi-film, and can peel off the multi-film in a straight line. Can be peeled off diagonally from the ridge.
