Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a belt-like material winding machine for winding up a material, such as a bandage, which has wrinkled due to washing or the like.

[Prior Art] Conventionally, belt-shaped objects are often wound into rolls for storage, transportation, or use.

For example, bandages can be washed and used repeatedly, but because they are formed into a band, they must be rolled into a roll before use.

However, since the bandage is formed using gauze, it wrinkles when washed. Therefore, when winding a bandage into a roll, the bandage must be rolled out from the tip to the left and right, making the winding process extremely troublesome and time consuming. Moreover,
The bandages had to be adjusted manually, which was unhygienic. Further, since it has wrinkles, it cannot be rolled evenly, making it difficult to use it again.

[Problems to be Solved by the Invention] As mentioned above, in the conventional technology for rolling up band-like objects such as bandages, the efficiency of the winding operation is low, it is unsanitary, and it is extremely difficult to roll it evenly. It was hot.

The present invention has been made in view of these problems, and its purpose is to provide an excellent belt-like material winding machine that is highly workable, hygienic, and capable of uniform winding. .

[Means for Solving the Problems] In order to solve the above problems, the belt hoisting machine of the present invention includes a swingable support arm that removably supports a hoisting shaft, and a hoisting A transmission member that is connected to the shaft and transmits the driving force of the motor and absorbs the displacement of the support arm; and a rotatable expansion roller that is close to the hoisting shaft and is bent in an F-shape and divided into two parts. ,
an anti-slip member provided on the surface of the expansion roller;
The structure is characterized in that it includes an elastic member provided so as to bias the winding shaft in the direction of the spreading roller.

[Function] The function of the present invention having the above configuration is as follows.

That is, the tip of the strip is brought into contact with the winding shaft,
The strip is placed on the upper surface of the spreading roller in a sufficiently spread state. Then, when the motor is operated while pulling the end of the strip with an appropriate force, the strip is wound into a roll around the winding shaft. At this time, since the spreading roller is divided into two parts in an F-shape, the strip is stretched in the left and right direction, and wrinkles do not occur in the strip. Moreover, since an anti-slip member is provided, the strip is not wrinkled. , it is possible to prevent the strip from shifting. Therefore, it is possible to uniformly and reliably wind up the strip into a roll. Further, even if the belt-shaped article is wound to a certain extent or more and becomes thick, the support arm swings, so that the belt-shaped article does not get jammed between the winding shaft and the spreading roller. Furthermore, since the transmission member absorbs the displacement caused by the swinging of the support arm, the driving force of the motor is reliably transmitted to the hoisting shaft, and hoisting is performed uniformly. Moreover, since the winding shaft is always urged in the direction of the spreading roller, the strip does not loosen.
After the strip has been rolled up, the winding shaft can be removed from the support arm and the strip can be extracted from the winding shaft.

[Example] A bandage winding machine will be specifically described based on the drawings as an embodiment of the band winding machine of the present invention as described above.

*Configuration of the embodiment* As shown in FIG. 1, the bandage winding machine 1 includes a machine base 2
An expanding roller 3 is rotatably provided on the upper support plate 2a, and a winding shaft 4 (upper side in the figure) and a guide bar 5 (lower side in the figure) are rotatably provided before and after the expanding roller 3.
Further, a drive motor 6 as a drive source is installed on the machine base 2, and the drive motor 6 is connected to a belt 7.
The transmission spring 8 is connected to the gear 8a of the transmission spring 8 via the transmission spring 8. In this embodiment, a bandage a that has wrinkles due to washing or the like is rolled up on a winding shaft 4. Further, in FIG. 1, the direction in which the bandage a is fed into the winding shaft 4 is upward in the figure. That is, when viewed from the feeding direction, the front side is the bottom side in the figure, and the back side is the top side in the figure.

The spreading roller 3 is composed of a pair of left and right rollers, and is arranged close to the winding shaft 4 and on the front side when viewed from the feeding direction of the bandage a. Of these spreading rollers 3, the left end of the right roller and the right end of the left roller, which face each other, are arranged near the center line of the bandage a, and are connected by engaging projections 3a as described later. Further, the right end of the right roller and the left end of the left roller are located closer to the front than the opposing ends of both rollers when viewed from the feeding direction of the bandage a.

Therefore, when the shaft is viewed from above, the roller shaft of the expansion roller 3 is inclined with respect to the winding shaft 4 so that the opposite end sides are narrowed, and the roller shaft has a substantially V-shaped shape when viewed from above. It is refracted in In addition, the expansion roller 3
When viewed from the horizontal direction, the roller axes are located at approximately the same height from the machine base 2 (Fig. 3).

As shown in FIG. 2, the expansion roller 3 has two cylindrical members arranged in an F-shape that are partially engaged with each other by a protrusion 3a. Further, the surface of the spreading roller 3 is provided with a concavo-convex member 3b which is used as an adhesive surface of magic tape to prevent the bandage a from slipping.

Further, as shown in FIG. 3, the winding shaft 4 is formed from three elastic metal wires 4a, and is provided with an attachment 9 and a support arm 10 at both ends thereof. The attachment 9 is removably fitted onto the metal wire 4a, while the support arm 10 has its base 10a installed on the machine base 2 and is swingable. This base portion 10a is movable in a direction parallel to the winding shaft 4, and is locked by a stopper 10b (FIG. 4). Further, the direction in which the support arm 10 swings is toward the back side when viewed from the feeding direction of the bandage a, and the support arm 10 swings in a manner that it falls down. Furthermore, the base 10 of the support arm 10
A spring 11 is attached near a.
This spring 11 is an elastic member as described in the claims, and its end portion engages with the support plate 2a, and urges the support arm 10 in the direction of the expansion roller 3. Further, a conduction spring 8, which is a conduction member, is rotatably connected to the support arm 10. The transmission spring 8 is composed of the gear 8a, a rotatable and freely movable spring shaft portion, and a portion connected to the support arm 10. Of these, the gear 8a is rotatably arranged on the support plate 2a of the machine stand 2. Therefore, the driving force from the drive motor 6 is transmitted to the gear 8a via the belt 7.
, the gear 8a rotates, which causes the spring shaft portion and the portion connected to the support arm 10 to rotate.

Further, as the support arm 10 swings, the part connected to the support arm 10 also swings, but at this time,
The spring shaft portion is configured to freely move in the same direction as the swinging direction of the support arm 10. Therefore, the spring shaft part is attached to the support arm 10.
The rotational force of the gear 8a is transmitted to the support arm 10 side.

On the other hand, as shown in FIG. 3, the guide bar 5 is
It is swingably attached to the support plate 2a and engaged with the limit switch 12 via a connecting member 12a. At this time, the connecting member 12a is biased toward the limit switch 12 side. Further, the limit switch 12 is electrically connected to the drive motor 6 and controls ON/OFF of the drive motor 6. That is, when the bandage a is lightly pulled toward the front (left side in the figure), the connecting member 12a is pulled via the guide bar 5, the limit switch 12 is turned on, and conversely, the force applied to the bandage a is released. Then, the guide bar 5 returns to the winding shaft 4 side, the connecting member 12a is urged toward the limit switch 12, and the limit switch 12 is turned OFF.

The guide bar 5 also includes a positioning guide 13.
is slidably installed, and is adapted to move depending on the width of the bandage a.

*Operation of the embodiment* The operation of this embodiment having the above-described configuration is as follows.

That is, the distal end of the bandage a, which has been washed and wrinkled, is passed under the guide bar 5 and is held between the metal wires 4a of the winding shaft 4 while making contact with the surface of the spreading roller 3. Then, adjust the positioning guide 13 according to the width of the bandage a, and lightly pull the bandage a toward you (leftward in FIG. 3). Then, the limit switch 12 is turned on, and the bandage a is rolled up around the winding shaft 4. At this time, in the spreading roller 3, the right end of the right roller and the left end of the left roller are located closer to this side than the opposing ends of both rollers when viewed from the feeding direction of the bandage a. Therefore, the left and right side edges of the bandage a are pulled in the left-right direction, and the bandage is rolled up while the wrinkles are stretched. Moreover, since the uneven member 3b provided on the surface of the spreading roller 3 prevents the bandage a from shifting, it is possible to reliably roll it up with the same width.

Further, as the bandage a is rolled up and its thickness increases, the support arm 10 swings to fall down. At the same time, the conduction spring 8 also moves freely and absorbs the displacement of the support arm 10. Therefore, a constant rotational force is always transmitted to the winding shaft 4, and the bandage a can be rolled up uniformly.

Furthermore, in this embodiment, since the limit switch 12 that controls the drive motor 6 is connected to the guide bar 5 via the connecting member 12a, the drive motor 6 can be turned off by simply relaxing the force applied to the bandage a in the forward direction. become. Therefore, in case, bandage a
Even if the wire is about to be wound up with a broken wire, the drive motor 6 can be stopped immediately and correction can be made easily.

When removing the bandage a rolled up as described above from the winding shaft 4, the following procedure is performed. That is, the stopper 10 of the base 10a of the support arm 10
b, and remove the hoisting shaft 4 along with the attachment 9 from the support arm 10. Then, the attachment 9 is removed from the winding shaft 4, and the metal wires 4a are pulled out one by one. This metal wire 4a is very thin and easy to pull out if it is one by one.Moreover, it has a moderate elasticity, so if you pull it out while swinging it from side to side, the roll shape of the bandage a will be removed. It won't collapse.

*Other Examples* The present invention is not limited to the above-mentioned embodiments, and any belt-like material can be rolled up. It is also possible to previously attach a core to the winding shaft and wind up the strip.

[Effects of the Invention] As described above, the belt-like material hoisting machine of the present invention is provided with a support arm that pivotally supports the hoisting shaft and a displacement absorbing member that absorbs displacement of the support arm in a swingable manner. It has a simple structure with a non-slip member on the surface and an expanding roller that is bent in an F-shape and split into two parts, making it highly workable, hygienic, and capable of uniform and reliable winding. It is possible to provide an excellent belt hoisting machine. In particular, according to the present invention, the strip can be rolled up while automatically stretching wrinkles caused by washing etc. by the spreading roller that spreads the strip in the left-right direction. Since the displacement caused by the swinging of the support arm is absorbed, the driving force of the driving source can be reliably transmitted to the hoisting shaft.
