Abstract

PURPOSE:To wind the floor sheet over a core without zigzag by pressure holding the core with six roll groups at the opposite sides of a frame and rotating the core as the frame travels. CONSTITUTION:When a core P for winding the floor sheet 25 is not fixed to the frame 1, the left and right wheels 6 can rotate independently while a caster 18 can rotate freely thereby the frame 1 can be pushed easily to desired position. In order to wind the floor sheet 25 over the core 25, the start of winding end of the floor sheet 25 laid on the floor is previously wound slightly over the core P pressure held at the opposite ends by means of three roller groups 13, 16 respectively. Then the frame 1 is pushed while grasping the handle 19 to rotate the roller groups 13, 16 through the wheel 6 and a frictional clutch 8 thus to wind the floor sheet 25 sequentially over the core P.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an example of a floor 7 sheet for winding 70 long strips made of various materials such as plastic and rubber.

Conventionally, in the work of laying or rolling up floor sheets on a vast floor, such as in a gymnasium, when laying a sheet, it is necessary to roll the rolled sheet onto the floor. Although it is easy to do, the work of winding up the sheet spread on the floor is particularly troublesome and laborious.2
This made it difficult to do anything, and the work efficiency was poor.Furthermore, it was impossible to wind it straight, and the edges tended to be uneven when rolled in a meandering manner (also known as bamboo shoot rolls), making it very difficult to clean up after winding.

Therefore, some attempts have been made to develop a traveling floor-sheet winding machine, but the conventional machines had various drawbacks such as physical difficulty, and there was no suitable one. .

The present invention has been made in view of the above, and it is an object of the present invention to provide a floor-sheet winding machine as described below to overcome the above-mentioned drawbacks and to meet the conventional demands of the industry.

The present invention will be described in detail with reference to embodiments shown in the drawings.

/ is a frame, and the left and right sides of the +iil 71N part are each provided with straight side plates /a. In the lower portions of the left and right side plates /a and /a, left and right pivot shafts 2 are respectively provided to protrude outward on the same horizontal axis tree in the lateral direction. First, large gears 3 are loosely fitted to the left and right axles 2, respectively, with bearings q and thrust bearings 5 interposed therebetween, so that they can rotate freely, and then clutches that can be fitted with friction pressure are attached to the outer surfaces of the large gears 2. Board g
The left and right wheels A, each having a friction clutch groove having a diameter a, are loosely fitted through a bearing 7 so that they can freely rotate and freely move axially. Finally, the left and right axles 2, 2 are screwed into the respective bases (outer end screw shafts), and the 54-node setscrews/Q are respectively 'Q'
It is equipped. Therefore, by appropriately tightening the left and right adjustment set screws 10, the left and right vehicles A are pressed inward through the respective coil springs, and each clutch plate and A are pressed against the large gear 3, respectively, and the friction clutch is created. The left and right axles and the left and right large-tooth AAA wheels are configured so that they can rotate integrally with respect to the left and right axles, respectively.

/1. // is on the left and right sides of the upper left and right side plates /a of the upper part of the left and right axle 2, respectively, on the horizontal ■ line in the left and right direction, respectively.
The front and rear passives +i11 on both the left and right sides were constructed with the intention of printing and translating freely, respectively, and the left and right passives @/
/ and // are small gears that mesh with the Ota wheel 3 on the outside.
2. /2, and drive trochanters 73 are also integrally wedged into the inner casing. Next /4Z.

/da is a left and right rotary grip /q which is respectively pivotally connected to the left and right side plates /a of the lower end part 2 by a pivot 75, and when each is vertically erected, each of the two front and rear drive trochanters /3 on both the left and right sides. ', 13
A freely rotatable trochanter is mounted at the apex position of a roughly 2'4-sided triangle. i.e. frame/
There are 1.2 driving trochanters/3 and 7 driving trochanters/Otsu on both the upper and left sides, respectively. Both portions of the winding core P are supported by the three trochanter groups on each of the left and right sides, as shown in the figure, and in this case, first, the rotary grip /ll or the fourth! When in the figure EN A position, the two front and rear drive trochanters/3. Place both ends of the winding core P on /3, then turn the rotating handle /≠ in the direction of the arrow, and place the trochanter on the straight line S tracing the center of the pivot 15 and the centers 0 and 2 of the winding core P. When the center of /B comes, the trochanter/B is in the state where it is most strongly pressed against the winding core P (the outer rubber ring of the trochanter/B is depressed by the pressure contact of the winding core P), but it is further from this state position. The rotary handle /l is rotated forward and stopped, and at that position the trochanter /6 is brought into pressure contact with the outer peripheral surface of the end of the winding core P, thereby supporting the winding core P under pressure. At this time, stoppers 77 are provided on both sides of the plate /a to prevent the rotary grip /≠ from rotating forward any further.

Therefore, forward rotation of the rotation grip /7i from the above state is prevented by the above-mentioned stopper 77, and the opposite rotation in the backward direction is prevented because the trochanter /7i is the strongest pressure contact point with the winding core P. Since it moves in the direction of a certain line S, it cannot be rotated arbitrarily. The trochanter/6 stably supports both ends of the winding core P under pressure without moving unnecessarily from the above state. Next, 7g is a caster (swivel leg) attached to the lower center of the rear part of the frame. Also, /9 is a handle at the upper end of the grip shaft /9a that extends diagonally backward and upward from the rear part of the frame. The handle part /9b is provided with levers 20 on the left and right sides, respectively, as shown in FIG. As shown in the figure, claw plates 2/ for preventing the rear small float/2 from reversing are provided, respectively, pivotally connected to each other by a support shaft 2). And the left and right nail plates 2
A spring 23 is tensioned in the darkness between the frame/ and one end of /, and of course, the left and right levers 20 of the handle part/9b are connected to the respective operating cables 2≠i81! tied together. In normal operation, the claw plates 2/2 are in the state shown by chain lines A in the figure due to the action of the spring 23, and the rear pinions/2 are in a state where they can rotate freely. When 0 is operated, the left and right pawl plates 2/ are rotated against the spring 23 by the indexing by both operating cables 2'l, and the respective pawls, 2/a, engage the left and right rear small gears 7.2. The state shown by the dotted line A in Figure 1 is reached, and the left and right rear drive trochanters/3 are prevented from reversing. E + 1 year old trochanter / 3] 1st turn IIJ city purchase T and the old man are sure. As described above, this invention uses three groups of trochanters on both the left and right sides to clamp and support both ends, respectively.
, ) The 5-core S is rotated as it is pushed by hand at a speed of 7 rams/time to wind up 70 strands of 25 strands. The above description is based on an actual example shown in the drawings, and the design can be modified as appropriate, for example, by using seven left and right drive trochanters/3, or by using a transmission mechanism other than a gear transmission mechanism.

Next, to explain the working state of the embodiment shown in the figure, first, as described above, the winding core P, whose both ends are supported under pressure by three groups of trochanters on each side, is placed on the floor as shown in FIG. The starting end of the floor sheet 25 being laid is placed in a slightly rolled state in advance, and the operator grasps the handle part 9bf of the push handle 9 to push the frame and move it.At this time, the winding core P Because the driving trochanters /3 of both the left and right fil are driven in a connected state by the clamping support of the frame /, the frame / moves straight and the floor-seat 2! is one that is sequentially wound onto the winding core P.

Since this invention is constructed as described above, when the core for winding the floor route E is not attached to the frame, the left and right wheels can rotate independently, and the casters can rotate freely, so that the frame When the winding core is pressed by the three trochanter groups on each side of the left and right sides of the frame, the drive trochanters on both the left and right sides, and therefore The wheels on both the left and right sides rotate as they are connected to each other, so if you push the frame normally, it will naturally move straight, so the floor and seat 2 will not wind in a serpentine or bamboo shoot manner. It has excellent effects such as being able to be wound straight around the winding core and being extremely efficient.

In addition, if the car floor sheet meandered during the winding process, if the worker tried to change the running direction of the frame by force in the meandering direction, the friction clutch would act like a car differential, and the clutch would Because the plate is not slippery, the meandering can be corrected arbitrarily while being pulled, and a friction clutch is used, so the floor to the winding core can be easily adjusted.
Even if the winding width increases, the left and right wheels will not slip and rotate, which will not interfere with sheet winding.

Furthermore, since the left and right drive trochanters are each equipped with a reversal prevention mechanism that is activated by lever operation, if the floor sheet sag or loosens during winding operation, the reversal prevention mechanism is activated. This has the effect of making it easy to straighten the floor sheet by pulling back T 7 L, -A. In addition, since the friction force of the friction clubchi is adjustable, it is effective to adjust the friction force appropriately according to the wear of the lining or the type of floor sheet, so that stable and proper work can be performed at all times. be.
