BACKGROUND OF THE INVENTION
The present invention relates to a multi-film stripping apparatus that strips and winds a multi-film covering a ridge.
[0002]
[Prior art]
Japanese Patent Publication No. 7-55104 is known as a multi-film stripping device for stripping and winding a multi-film from a multi-film-coated ridge. The stripping device described in this publication is provided with a winding device that winds a multi-film on a cart with a handle that is gripped by an operator, and a driving device that rotates the winding device. When the multi-film is taken up by the apparatus, the carriage is pulled forward by the tension applied to the multi-film.
[0003]
[Problems to be solved by the invention]
This multi-film stripping device is a dedicated machine that does not require any other working machine such as a tractor (previously it was installed as an auxiliary device such as a tractor) and can be manufactured at a low cost. There is an advantage that it does not require a driving device for traveling because it is pulled forward by the tension applied to the multi-film at the time.
However, this multi-film stripping device has the inconvenience that it is necessary for the operator to always hold the handle and walk on the stripping device. Also, if the multi-film is covered with a thick soil or if the soil is hard, a large force is required to peel off the multi-film, and if so, the tension applied to the multi-film will increase and the multi-film will be cut during winding. There was a problem.
[0004]
The present invention is a multi-film stripping device in which a carriage moves forward by tension applied to a multi-film to be wound, so that the operator can automatically wind even without sticking to the device. In this case, the object is to prevent the multi-film from being cut, and to enable optimum stripping under various conditions.
[0005]
[Means for Solving the Problems]
The present invention includes a winding device that winds a multi-film and a drive device that rotationally drives the winding device on a cart that includes a front wheel and a rear wheel and that runs independently across a multi-film-covered cage. In the multi-film stripping device in which the carriage moves forward by the tension applied to the multi-film to be taken, a guide roller that reciprocally swings up and down by the driving device is installed above the winding device, It is hung on the guide roller, and is wound around a winding device via the guide roller. Note that the self-supporting traveling means that the vehicle can stand on its own wheels and travel without being supported manually (in the stripping device of the above publication, the operator supports the vehicle with a handle).
[0006]
In the above stripping device, the front wheel and the rear wheel are installed on the carriage so that the vehicle can run independently, so that the winding can be automatically performed without the operator sticking to the device. In addition, a guide roller is installed above the winding device so that the multi-film is wound on the winding device via the guide roller, so that the pulling angle of the multi-film becomes large and it becomes easy to peel off from the ground surface. . Furthermore, swinging the guide roller back and forth up and down will cause the multi-film to be shaken with strength, just as when the multi-film is peeled off from the ground surface by hand. The multi-film can be easily peeled off from the ground surface, and the attached soil can be removed. Therefore, excessive tension is not applied to the multi-film, and the cutting is prevented.
[0007]
If the guide roller is installed directly above or near the front side of the rear axle, the load applied to the front wheel during winding is relatively reduced, and the carriage can be smoothly moved without slipping into the ground. The multi-film is prevented from being cut by the forward movement. (Because the guide roller is loaded downward by the multi-film tension, if the guide roller is in front, the load applied to the front wheel increases, and the front wheel It will be difficult to move forward due to slipping inside, and the tension applied to the multi-film will become higher and cut.)
[0008]
The present invention also includes a winding device that winds the multi-film and a driving device that rotationally drives the winding device on a cart that includes the front wheels and the rear wheels and that runs independently across the multi-film covered ridge. In the multi-film stripping device in which the carriage moves forward due to the tension applied to the multi-film to be wound, a guide roller is installed above the wind-up device, and the multi-roller at the time of winding is placed on the front side of the guide roller. A stop device for detecting that the film pulling angle has become larger than the normal value and stopping the winding is installed, and the multi-film is hung on the guide roller and wound on the winding device via the guide roller. It is characterized by that. In this case, since the multi-film descends from the normal position on the front side of the carriage, it is the same even if it is detected. In addition, it is desirable to combine the structure of this invention (point which provides a stop device) with the structure of the said invention .
[0009]
If the multi-film is difficult to peel off, the cart will move forward as the multi-film is wound, so the pulling angle of the multi-film will gradually increase, the cart will become difficult to move forward, the tension applied to the multi-film will increase, and if left Lead to cutting. The stop device has a function of stopping winding and preventing cutting of the multi-film at such time.
The stop device includes, for example, a swing arm that is erected so as to be able to rotate and swing toward the rear of the vehicle body, and a horizontal detection member that is attached to the upper portion of the swing arm. The pulling angle is detected by swinging the swing arm backward by a predetermined angle. For example, a horizontally supported roller may be used as the detection member. The stop device may be provided with a lock device for fixing the swing arm so as not to rotate and swing.
[0010]
Moreover, the multi film guide part extended upwards can be provided in the both ends of this detection member. By winding the multi-film through the space between the multi-film guides, it is possible to prevent the multi-film from coming off from the detection member. Furthermore, a portal-type multifilm passage guide through which the multifilm passes can be installed between the multifilm guide section and the guide roller. You may install the roller which contact | abuts a multi film and rotates on both sides of this multi film passage guide. The film passage guide cooperates with the multi-film guide portion to prevent the multi-film from deviating from the normal passage route.
[0011]
In the multi-film stripping device described above, the front and rear wheels can be adjusted in the left-right position, and / or the relative height of the front and rear wheels with respect to the carriage can be adjusted. In this case, it is desirable that the front and rear wheels can be adjusted in the left-right position for each wheel, or the vertical positions of the front and rear wheels with respect to the carriage can be adjusted for each wheel .
In addition, a clutch that interrupts power transmitted from the driving means to the winding device can be provided.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to FIGS.
The multi-film stripping device shown in FIGS. 1 and 2 includes a pair of front wheels 1, 1 and rear wheels 2, 2, a carriage 3 that runs independently across a multi-film covered ridge, and a rear side of the carriage 3. The multi-film F winding device 4 installed in the engine, the engine 5 that rotationally drives the winding device 4, the power transmission mechanism 6 that transmits the driving force of the engine 5 to the winding device 4, and the upper front side of the winding device 4 The guide roller 7 is installed on the front side, the swing mechanism 8 is configured to swing the guide roller 7 up and down by the driving force of the engine 4, and the stop device 9 is provided on the front side of the guide roller 7.
[0013]
The power transmission mechanism 6 includes a speed reducer 11, a sprocket 12, a chain 13, and a sprocket 14, and transmits the driving force of the engine 5 to a main shaft 27 described later of the winding device 4.
The swing mechanism 8 includes a crank mechanism 15 that is driven by the engine 5 via the speed reducer 11, a transmission rod 16, a swing shaft 19 that is supported at both ends by bearings 18 that are fixed to a pair of brackets 17, It consists of plate members 21a, 21b, etc. that are fixed in the vicinity of both ends of the moving shaft 19 and pivotally support both ends of the guide roller 7 at the tip, and the upper end portion 16a of the transmission rod 16 is at the rear extension of one plate member 21a. The transmission rod 16 is moved up and down by the rotation of the crank mechanism 15, the plate member 21a (and 21b) is swung around the swing shaft 19 (bearing 18), and the guide roller 7 is also swung up and down. Move.
It is desirable that the guide roller 7 is located immediately above or near the front side of the axis of the rear wheel 2. This is for reducing the load applied to the front wheel 1 as described above and making the carriage 3 easy to move forward. According to the experiment in the field, the angle (θ) formed by the straight line passing through the axis of the rear wheel 2 and the axis of the guide roller 7 and the vertical line passing through the axis of the rear wheel 2 is about 15 degrees forward. When the vehicle is within, the carriage 3 has moved forward without the front wheel 1 being relatively displaced. Therefore, this is a guide for the installation position of the guide roller 7.
[0014]
The stop device 9 includes a swing arm 23 pivotally supported by a pair of brackets 22 on the carriage 3, and a detection roller pivotally supported horizontally and rotatably at the upper end of the swing arm 23. 24, a transmission wire 25 attached to the lower end of the swing arm 23, and the like. The transmission wire 25 is normally located at the position shown by a biasing force of a spring (not shown), and the swing arm 23 stands upright, but a backward load is applied to the detection roller 24 and the swing arm 23 tilts backward (see FIG. 1), the transmission wire 25 is pulled forward against the urging force of the spring, and this acts on an accelerator lever (not shown) of the engine 5 and pulls it back to the low rotation side. Stop rotation.
[0015]
Therefore, when the multi-film F is difficult to peel off, while the winding is continuously performed and the carriage 3 moves forward, the pulling angle (δ) of the multi-film F gradually increases (= the multi-film F descends). The detection roller 24 is pushed rearward by the multi-film F, the swing arm 23 is inclined rearward, the engine 5 is rotated at a low speed via the transmission wire 25, and the rotation of the winding device 4 is stopped. As described above, the tension applied to the multi-film F does not increase and cutting is prevented. When the rotation of the winding device 4 stops, the multi-film F may be peeled off to some extent by hand, and winding by this device may be started again.
[0016]
The winding device 4 is installed on the rear side of the guide roll 7, and as shown in FIGS. 3 and 4, a main shaft 27 having one end pivotally supported on a bearing 26 fixed at a predetermined position on the carriage 3, a main shaft A plurality of winding members (six in this example) are disposed around the periphery of the main shaft 27 to constitute a winding shaft, and a boss member is detachably fitted to the other end of the main shaft 27. 29, a retaining member 31 for screwing and fixing the boss member 29 to the main shaft 27, a bearing 32 which is detachably fitted to the outer periphery of the boss member 29 and supports the boss member 29 rotatably. 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. Further, a roller 39 corresponding to each take-up shaft constituting member 28 is attached inside the flange plate 36.
[0017]
The take-up shaft constituting member 28 is attached to a bracket 41 attached to the outer periphery of the main shaft 27 via links 42 and 42 (which forms a so-called parallel link mechanism), and the main shaft 27 is kept parallel to the main shaft 27. 27 or a predetermined distance. In the unloaded state, each take-up shaft constituting member 28 is urged by a spring 43 and is separated from the main shaft 27 as shown in FIG. 3, and one end thereof passes through a hole 33 a formed in the flange plate 33 to be brought into contact with the contact plate 35. Abutting and positioning is performed. At this time, the parallel links 42 and 42 are not perpendicular to the main shaft 27 but slightly inclined toward the boss member 29.
The bearing 32 is rotatably attached to a frame 45 supported on the carriage 3 so as to be swingable around the support portion 44 via a pair of pins 46. The bearing 32 oscillates around the support portion 44 when fitted to or extracted from the boss member 29, but since it is pivotally attached via the pin 46, it can always be kept parallel to the boss member 29. Can be installed and removed without any problems.
[0018]
When 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 in contact with the contact plate 35 as described above. Then, the other end of each winding shaft constituting member 28 slides on the corresponding roller 39, passes through the hole 36 a formed in the flange plate 36, and comes into contact with the contact plate 38. Next, the frame 45 is raised, the bearing 32 is fitted to the boss member 29 from the outside, and the retaining member 31 is screwed into the other end of the main shaft 27 with the handle 47 to fix the boss member 29 to the main shaft 27. The bearing 32 is held in the fitting position.
Thus, one end of the main shaft 27 is rotatably supported by the bearing 26, and the other end is rotatably supported by the bearing 32 together with the boss member 29. Also, each winding shaft constituting member 28 is supported at both ends by the contact plates 35 and 38 and maintains its position, and the inner side (main shaft side) is supported by a roller 39, which is the winding shaft (multi-film The rotating shaft is wound up.
[0019]
At the time of winding the multi-film, the carriage 3 is placed straddling the multi-film-covered cage, and the end of the multi-film is first peeled off by hand, the guide roller 7 is passed, and the take-up shaft constituting member 28 is formed. It winds so that it may not remove | deviate to a winding shaft to be transmitted, and transmits the driving force of the engine 5 to this winding device. When the main shaft 27 rotates and winding of the multi-film F starts, the multi-film F is peeled off from the ridge by the tension applied to the multi-film F and the swinging action of the guide roller 7, and the attached soil is removed. On the other hand, the carriage 3 is automatically pulled forward by the tension applied to the multi-film F, and during this time, the operator does not have to stick.
[0020]
If there is a part where the peeling of the multi-film F does not go smoothly, the winding is continued even at that time, so that only the carriage 3 advances, and the inclination angle δ of the multi-film F increases. . As the inclination angle δ increases, the force component acting on peeling increases even with the same tension, which may cause the multi-film F to be peeled off again. In that case, the inclination angle δ is restored, but when 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. This pushes and swings the swing arm 23 backward. As a result, 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 forward movement of the carriage 3 is also stopped. If the inclination angle δ becomes too large, the load applied to the front wheel 1 increases, making it difficult for the carriage 3 to move forward, increasing the tension applied to the multi-film F and facilitating cutting. F disconnection is automatically prevented. When the cart 3 is stopped, it is preferable to operate this apparatus again by removing the hard soil by an operator.
[0021]
When the winding of the multi-film F is completed, the handle 47 is turned to remove the retaining member 31 from the main shaft 27, the frame 44 is tilted outward, the bearing 32 is extracted from the boss member 29, and the boss member 29 is further extracted from the main shaft 27. . Next, the parallel link mechanism is tilted to reduce the diameter of the take-up shaft constituted by each take-up shaft constituting member 28, and the multi-film wound around the periphery is extracted. The multi-film is wound around the winding shaft constituting members 28 in multiple layers and strongly compressed in the diameter reducing direction. However, since the diameter of the winding shaft is reduced, the multi-film can be easily pulled out.
[0022]
In the multi-film stripping device, it is desirable to provide a manual clutch that interrupts the power transmitted from the engine 5 to the winding shaft of the winding device 4. If this clutch is set to “disengaged”, the operator can arbitrarily rotate the winding shaft, so that the end of the multi-film can be easily wound and fixed to the winding shaft at the beginning of winding.
[0023]
In addition, the stop device 9 may be provided with a lock device that locks the swing arm 23 in the upright position so as not to rotate and swing so that the operator can arbitrarily select the locked state or the unlocked state. When the operator locks the swing arm 23 in the upright position, the swing arm 23 does not swing backward even when the pulling angle of the multi-film F is increased. Therefore, the winding device 4 does not automatically stop and winding is continued. The Therefore, for example, when the multi-film is stronger than a general one, there is no risk that the multi-film will be cut even if a little excessive tension is applied. Just keep it.
[0024]
In the above example, the front side of the stripping device is directed in the direction of laying the multi-film, and the stripping device is advanced along with the winding, but on the contrary, the rear side of the stripping device is It is possible to wind the stripping device while retracting the stripping device in the direction of laying the multifilm. In this case, as shown in FIGS. 5 and 6, the stripping device is moved backward on the multi-film F, the multi-film F is folded back on the front side of the stripping device, and the leading end is wound up via the guide roller 7. It winds around the winding shaft of the device 4. Winding is started by increasing the number of revolutions of the engine 5, and the operator holds the handle 48 and pulls the peeling device backward (arrow). 49 is a bag.
[0025]
When stripping the multi-film in a straight line by advancing the stripping device, the multi-film may wind in a strong wind, etc. Then, since the multi-film is stepped on by the operator and the wheel of the stripping device, the multi-film is not greatly swollen even if it is subjected to a strong wind and is not cut.
[0026]
The stripping device shown in FIG. 7 to FIG. 9 differs in the structure of the stopping device 51 and the point that a multi-film passage guide 52 is installed between the stopping device 51 and the guide roller 7. It is basically the same as the picking device (the same number is assigned to the same part).
The only difference between the stop device 51 and the stop device 9 is that a multi-film guide portion 54 extending upward is provided at both ends of the detection roller 53. The guide portion 54 has a rod shape in which both swing arms 55 extend upward beyond the detection roller 53. The multi-film passage guide 52 is composed of struts 56 on both sides and beam portions 57 connecting the upper ends thereof, and has a gate shape as a whole.
[0027]
Between the guide portions 54 and in the passage guide 52 is a passage path for the multi-film F, and the multi-film F is wound around the winding device 4 via the guide roller 7 through the passage. When the wind is strong or the like, the multi-film winds up and beside it and may deviate from the normal passage route up to the guide roller 7, but these can be prevented by installing them.
In addition, it is more desirable to install rollers that rotate in contact with the multi-film on the support columns 56 on both sides of the passage guide 52. Similarly, a roller may be installed in the guide unit 54.
[0028]
The stripping device shown in FIGS. 10 to 13 is different in that the front and rear wheels can be adjusted in the left-right position for each wheel, and the vertical positions of the front and rear wheels with respect to the carriage can be adjusted for each wheel. Except for this point, it is basically the same as the stripping device described so far (corresponding portions are given the same numbers).
A wheel support frame 61 having a hollow cross section is installed horizontally on the carriage 3, and a horizontal support arm 62 of each wheel is inserted into the wheel support frame 61, and a vertical support arm 63 of each wheel is attached to both ends of the horizontal support arm 62. . The vertical support arm 63 includes a hollow cross-section frame portion 64 fixed to the horizontal support arm 62 and an arm portion 65 inserted into the frame portion 64. The axle of each wheel is fixed to the arm portion 65. .
Each horizontal support arm 62 is slidable with respect to the wheel support frame 61, and each arm portion 65 is slidable with respect to each frame portion 64, and can be fixed at an appropriate position by screws 66 and 67. 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 each wheel is adjusted by being expanded or contracted horizontally or vertically. Adjustment can be performed smoothly.
[0029]
In this stripping device, the distance between the wheels can be adjusted as appropriate, so that an appropriate distance can be set according to the width of the flange 49 as shown in FIG. 12, and the positions of the front wheel 1 and the rear wheel 2 can be set. By shifting the to the left and right, it is possible to prevent the running resistance from increasing due to the rear wheel (or front wheel) being fitted after the front wheel (or rear wheel) has passed.
On the other hand, since the height of the vehicle body can be adjusted as appropriate, it can be set to an appropriate height corresponding to the height of the collar 49 as shown in FIG. In addition, even if the heel itself is low but it is taller with a pillar standing up and tunneled, if you raise the body, you can run on the heel without being caught by the pillar.
[0030]
【The invention's effect】
According to the present invention, in the multi-film stripping device in which the carriage moves forward by the tension applied to the multi-film to be wound, the winding can be automatically performed without the operator sticking to the device. In that case, the multi-film can be prevented from being cut. Also, the attached means enables optimum stripping under various conditions.
