TECHNICAL FIELD OF THE INVENTION
The present invention relates to a winder that is manually operated to remove a long floor sheet laid on a floor of a dome stadium, a gymnasium, or the like after use. In particular, the present invention relates to a winder capable of winding a floor sheet without any problem even if the floor sheet winds up and the weight increases. In addition, the present invention relates to a winder having good operability, which makes it easy to temporarily wind a floor sheet on a cart and can smoothly proceed to the next winding work. Further, the present invention provides a floor sheet winding machine that can cleanly wind a floor sheet without being biased to one side and wound up in a bamboo shoot shape.
[0002]
[Prior art]
In recent years, floor sheets have been laid on floors of indoor stadiums such as a dome stadium and a gymnasium. These facilities are often used for multiple purposes. Therefore, the floor sheet must be removed every time the event is held. For example, a floor sheet is laid in the gymnasium at the time of the event, and after that, the floor sheet is removed and returned to the floor surface for the next sports competition. Since such a process is repeated, the frequency of winding the floor sheet is high. In each case, it is not easy to secure manual labor for the winding operation, and the winding operation is a bottleneck. Therefore, there is a need to develop a winder that can be worked alone and that can wind a floor sheet neatly.
[0003]
FIG. 1 is a perspective view and FIG. 2 is a side view of a conventional floor sheet winder. The bogie 20 serving as the main body of the floor sheet winder A has box-shaped frames 21 and 21 'on the left and right. Wheels 1 and 1 'are mounted on the left and right sides of the front of the frame, and casters 22 are mounted on the center of the rear of the frame. In addition, a handle 23 for pushing is provided at the rear of the carriage 20. Winding of the floor sheet is performed while pushing the handle of the cart and running. At this time, the running force of the wheels is the force for winding the floor sheet B. The operation of winding will be described later. A guide roller 24 is attached to a front end of an arm 26 in front of the frames 21 and 21 '. Next, FIG. 3 shows a front view of the transmission mechanism for winding the floor sheet, and FIG. 4 shows a side view thereof. The main part of the bogie 20 includes left and right wheels 1, 1 'and an axle 2 connecting these wheels. A differential device 7 is provided at the center of the axle 2. In addition, rolling wheels 5, 5 ′ are provided on one side of the bogie 20 via a chain 3 and a gear group 4. The other side is provided with rolling wheels 5, 5 'via an intermediate shaft 8 and a gear group 4'. Here, the rolling wheels 5, 5 'are roller-shaped with a short shaft length. Covering the entire center of the floor sheet winding machine is the floor sheet B being wound on the winding core 6.
[0004]
Hereinafter, the operation of winding the floor sheet B will be described. The user pushes the handle 23 to move the cart 20. When the wheel 1 rotates, the running force of the wheel is transmitted to one of the rolling wheels 5, 5 'via the chain 3 and one of the gear groups 4. The running force of the wheels is transmitted to the other rolling wheels 5, 5 'via the intermediate shaft 8 and the other gear group 4'. These forces are transmitted to the winding core 6 resting on the rolling wheels. The floor sheet B is guided by the guide roller 24 at the front end of the arm 26 in front of the frame, and is wound on a winding core on a cart. Here, the guide roller has a rod shape longer than the width of the floor sheet. When this type of winder goes straight, the left and right wheels rotate at the same peripheral speed. However, when traveling on a curve, the differential device 7 operates to absorb the rotation difference between the left and right wheels. Further, when the winding is not performed, for example, after the winding of the floor sheet is completed, the clutch (not shown) connected to the gear group 4 on the chain 3 is disengaged, so that the transmission to the rolling wheels can be performed. When released, the wheels 1, 1 'rotate freely. As a result, the carriage can be easily pushed by hand.
[0005]
[Problems to be solved by the invention]
However, the winding core 6 is only supported by the narrow rolling wheels 5 and 5 'having a short shaft length at both ends in the width direction of the floor sheet B. Therefore, as the winding diameter increases and the weight of the winding core increases, a large load is locally concentrated on the four left and right rolling wheels. As a result, the rolling wheel slips or stops.
[0006]
Further, the rolling wheels 5 and 5 'at both ends have a short shaft length and a narrow width, so that the entire width of the floor sheet B cannot be supported. When the floor sheet is placed directly on the rolling wheel, the center is concave. Therefore, when temporarily winding the floor sheet around the winding core 6, the floor sheet is temporarily spread on the floor, and the winding core is placed thereon, and then the front end of the floor sheet is temporarily wound around the winding core. I do. After that, the temporarily wound winding core is placed on the rolling wheel. In this way, it is impossible to temporarily wind the rolling directly on the rolling wheel, and it takes a double effort. Further, it is not easy to put a heavy take-up core on a rolling wheel by itself.
[0007]
Further, the floor sheet B is guided by the guide roller 24 at the tip of the arm 26 in front of the frames 21 and 21 'of the cart, and is wound around the winding core 6 on the cart. The guide roller has only a rotational movement, and its axial movement is restricted. As a result, during winding, the floor sheet is biased to one side and a dullness occurs. However, it has been pointed out that the floor sheet cannot be reduced or absorbed.
[0008]
In view of the above circumstances, the present invention can prevent the rolling rotation of the rolling wheel from slipping or stopping even when the winding diameter of the winding core is increased and the weight is increased, and the force that always winds the floor sheet. Is provided. It is another object of the present invention to provide a winder having good operability, which allows a user to temporarily roll a floor sheet. Another object of the present invention is to provide a floor sheet winding machine that reduces and absorbs one-sided bias and dullness that occurs in the floor sheet and does not cause bamboo shoots or wrinkles.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a device in which a long floor sheet laid on the floor is wound while the bogie is pushed by hand, and the traveling force of one wheel is reduced by one. And the traveling force of the other wheel is transmitted to the other rolling wheel via the other gear group. A floor sheet winder in which driving wheels are provided in parallel, the floor sheet is mounted on the rolling wheels, and a winding core is rotatably mounted thereon.
[0010]
A second aspect of the present invention is a floor sheet winder including a floating roller at a front portion of a carriage and guiding a floor sheet onto the carriage, in addition to the features of the first aspect of the invention.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be specifically described below based on embodiments of the present invention illustrated in the accompanying drawings.
[0012]
FIG. 5 shows an embodiment of the present invention and is a plan view of a floor sheet winder. FIG. 6 is a side view. FIG. 7 is a plan view of a transmission mechanism for winding the floor sheet. FIG. 8 is a side view.
[0013]
First, as shown in FIGS. 5 and 6, a bogie 20 serving as a main body of the floor sheet winder A has left and right frames 21 and 21 ′. Wheels 1 and 1 'are mounted on the left and right sides of the front of the frame, and casters 22 are mounted on the center of the rear of the frame. In addition, a handle 23 for pushing is provided at the rear of the carriage 20. In addition, a floating roller 25 serving as a guide when winding the floor sheet B is provided at the front portion of the frame. Here, the floating roller is formed by arranging a plurality of short rollers in the axial direction, and rotates and slightly moves in the axial direction.
[0014]
The configuration of the transmission member of the floor sheet winder will be described with reference to FIGS. A gear group 4 is connected to one of the wheels 1 and then to a rolling wheel 5. The other wheel 1 'is connected to 4' and then to the rolling wheel 5 '. The transmission member on one wheel 1 side and the transmission member on the other wheel 1 'side are each independently configured as a transmission mechanism. Here, the rolling wheel has a rod shape longer than the width of the floor sheet. Further, the rolling wheels 5 and 5 'are provided in parallel with each other. A floor sheet B is placed on the rolling wheel, and a winding core 6 is placed on the floor sheet B so as to be rotatable, and the floor sheet is wound.
[0015]
Next, the operation of the transmission member will be described. By pushing the handle 23 by hand, the floor sheet winder runs. The running force of the wheels is transmitted to the rolling wheels via a gear group. This force is transmitted to the floor sheet B on the rolling wheel, and the floor sheet is wound around the winding core 6.
[0016]
At this time, the running force of the wheels is transmitted to the rolling wheels separately for the left and right wheels. That is, the running force of the wheels is independently transmitted to the rolling wheel 5 via one gear group 4 and to the rolling wheel 5 'via the other gear group 4'. This point is different from the related art in which left and right transmissions are linked.
[0017]
The rolling wheel for transmitting the force for winding the floor sheet B is not a narrow shaft having a short shaft length unlike the conventional winding machine. It is a long axis that supports the entire width of the floor sheet. This point is also different from the conventional rolling wheel. Therefore, since the load is not locally concentrated on the rolling wheels, the rolling wheels do not slip or stop and the winding force is always transmitted to the floor sheet. That is, even if the diameter of the winding core increases and the weight increases, the winding force is always transmitted to the floor sheet, and the winding does not suddenly stop.
[0018]
In addition, as described above, the running forces from the wheels are independently transmitted to the rolling wheels 5 and 5 '. Therefore, even when one wheel slips or does not rotate, the other rolling wheel rotates, so that the floor sheet B can be wound up correctly. In addition, since the left and right rolling wheels are not directly connected and interlocked, the vehicle can easily travel on a curve without a differential device that absorbs the rotation difference between the left and right wheels as in the related art. Further, even when winding is not performed, for example, after winding of the floor sheet is completed, the bogie can be easily pushed by hand without requiring a conventional clutch (not shown).
[0019]
A plurality of floating rollers 25 are provided in the front part of the winder in the axial direction. The floor sheet B is guided on the floating roller, and is wound on the winding core 6. Here, the floating roller 25 freely rotates while slightly moving in the left-right axis direction. That is, the floating roller rotates and moves in the axial direction like an abacus ball. Since the floor sheet B is placed on the floating roller and guided while freely rolling and sliding toward the winding core 6, the movement in the width direction is not restricted, and the dullness is reduced and wrinkles are not generated. Also, the floor sheet is not biased to one side and is not wound up in a bamboo shoot shape.
[0020]
Next, the procedure of the winding operation will be described. Since the rolling wheels 5 and 5 'are of a long axis supporting the entire width of the floor sheet B, the center of the width is not depressed even if the floor sheet is directly placed on the rolling wheel. Therefore, the temporary winding operation can be performed on the rolling wheel. First, the floor sheet B is spread on the floor, and its tip is folded back by about 1 meter. Next, the floor sheet that has been folded back by about 1 meter is dragged up to the winder side and placed on the rolling wheels 5, 5 '. Next, the take-up core 6 is placed on the floor sheet, and the protruding portion of the floor sheet that is folded at the end is wound around the take-up core. Thus, the preparation work for winding is completed, and then the floor sheet is wound on the winding core 6 by running while pushing the handle 23 of the cart manually. As in a conventional winding machine, a floor sheet is temporarily spread on a floor, a winding core is placed thereon, and the front end of the floor sheet is temporarily wound. After that, there is no need to double the work of placing the winding core in the temporarily wound state on the rolling wheel. In addition, since the heavier winding core is not placed on the rolling wheel by itself, the temporary winding work can be performed alone.
[0021]
【The invention's effect】
The floor sheet winder according to the present invention can support the entire floor sheet in the width direction by the long rolling wheel. That is, since the rolling wheels do not receive the load of the wound floor sheet locally and concentratedly, slip rotation or stop of the rolling wheels can be prevented. The winding force can always be transmitted to the floor sheet. Even if the diameter of the winding core is increased and the weight is increased, the winding force is always transmitted to the floor sheet, so that the winding does not suddenly stop.
[0022]
Even if one wheel slips or stops rotating, the running force of the wheel is transmitted to the other rolling wheel, so that the winding core rotates normally and the floor sheet is correctly wound. Can be taken.
[0023]
The rolling wheel has a long axis shape that supports the entire width of the floor sheet. Therefore, even if the floor sheet is directly placed on the rolling wheel during temporary winding, the center of the width does not become depressed. Therefore, a temporary winding operation can be performed by one person.
[0024]
The floor sheet rests on the floating roller, rolls and slides freely and is guided toward the winding core, so that the movement in the width direction of the floor sheet is not restricted, and the dubble of the floor sheet is reduced. No wrinkles occur. Also, the floor sheet is not biased to one side and is not wound up in a bamboo shoot shape.
[0025]
Since the floating roller does not protrude forward of the bogie, after winding is completed, the bogie can be tilted obliquely and the core can be kicked forward. The work of lowering the core can be done alone.
[0026]
As described above, the operability is good even for a first-time user, and the floor sheet can be neatly wound.
As an additional effect, the winding diameter can be increased. Since the top of the truck of the floor sheet winder is open, it can be wound up to about 600 mm in diameter while rolling on two rolling wheels.
