Description

[Detailed explanation of the idea] The present invention relates to a calendar winding device.

Conventionally, when shipping calendars, they were rolled up into a cylinder and placed in a plastic bag or the like.

Calendars were rolled up by hand, which meant that the thickness of the rolls was inconsistent, and if they were too thick, they wouldn't fit in the bag, and it took a long time to roll them up.

This invention was made to solve the above problems, and the thickness of the roll is constant,
Another object of the present invention is to provide a calendar winding device that can wind winding quickly.

That is, the gist of the present invention is a calendar winding device comprising a calendar winding rod, an electric motor for rotating the winding rod, and a switch section for activating or stopping the electric motor.

Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is a schematic perspective view of a calendar winding device 1 of the present invention.

The calendar winding device 1 of the present invention comprises a calendar winding rod 3, an electric motor 5 for rotating the winding rod 3, and a foot switch 7 for operating or stopping the electric motor 5.

A support shaft 9 is connected to one end of the winding rod 3, and the support shaft 9 is rotatably attached to a housing 13 by a bearing 11.

A pulley 15 is fixed to the support shaft 9, while
A pulley 19 is also attached to the rotating shaft 17 of the electric motor 5 attached to the housing 13, and a belt 21 is hung between the pulleys 15 and 19, so that the rotation of the rotating shaft 17 is transmitted to the support shaft 9. In order to rotate the winding rod 3 at a desired speed, the diameters of the pulleys 15 and 19 may be changed appropriately.

A foot switch 7 is connected to the electric motor 5 through one cord 23, and a main switch 26 is connected through another cord 24, and a plug 16 is connected to the main switch. Further, the foot switch 7 and the main switch 26 are connected via a cord 18, and the electric motor 5 can be started or stopped by stepping on the foot switch 7 while the main switch 26 is turned on. There is.

The calendar winding device 1 of the present invention is not limited to the embodiments described above, and for example, the winding rod 3 is extended without providing a support shaft 9 and the winding rod 3 is directly supported by a bearing 11. It's okay. Furthermore, instead of connecting the electric motor 5 and the support shaft 9 via the belt 21, the rotating shaft 17 of the electric motor 5 may be directly connected to the winding rod 3. In this case, it is preferable to connect the electric motor 5 and the winding rod 3 via a suitable speed reducer.

Next, a method of using the calendar winding device 1 of the present invention will be explained.

As shown in the first figure, after one end of the calendar 25 is wrapped around the winding rod 3, the electric motor 5 is activated by stepping on the foot switch 7, and the winding rod 3 is rotated as shown by arrow A through the belt 21. Calendar 25
Wind up. When winding, a hand is placed to prevent the calendar 25 from shifting in the axial direction of the winding rod 3 and being wound.

By the way, as shown in the second figure, if a guide 27 is attached to one side of the winding rod 3 and the side end of the calendar 25 is pressed against it, the calendar 25 can be easily wound so as not to shift in the axial direction of the winding rod 3. You can take it.

After winding, the calendar 25 is moved in the axial direction of the winding rod 3 as shown by arrow B in FIG. Carefully remove the plastic bag and calendar 25 from the wrapping rod 3.

In order to easily attach the calendar 25 to the winding rod 3, one end of the leaf spring 29 is fixed to the winding rod 3 along the circumferential direction with a screw 28, as shown in FIGS. 3a, b, and c. On the other hand, the leaf spring 2 of the wrapped rod 3
The ball 33 is fixed to the plate spring 29 by the coil spring 35 housed in the hole 31 formed at the fixed position of the plate spring 29.
It is also possible to provide a calendar holding part 30 which is pressed against the calendar 25 and insert the end of the calendar 25 between the leaf spring 29 and the ball 33 to hold it there. Leaf spring 2
9 to the winding rod 3, a notch 32 is formed in the side wall of the winding rod 3, and the head of the screw 28 is attached to the winding rod 3.
It is preferable not to expose the surface of the side wall.
In order to remove the calendar 25 from the winding rod 3, it is only necessary to shift it in the axial direction of the winding rod 3.

Further, the plate spring 29 is attached to the winding rod 3 as shown in the fourth figure.
It may be installed parallel to the axial direction.

Next, as shown in Figure 5, a groove 37 may be formed in the winding rod 3 that reaches the end surface of the winding rod 3 and is parallel to the axial direction, and the end of the calendar 25 may be inserted therein.

Furthermore, as shown in FIG. 6, a hollow shaft with one end face closed and the other end face open is used as the winding rod 3,
A large number of air suction holes 39 are provided on the side wall of the winding rod 3, and a hollow support shaft 9 is provided on the open end surface of the winding rod 3.
One open end surface of the support shaft 9 may be provided in series, and an air suction pump 43 may be connected to the other open end surface of the support shaft 9 via a hose 41.

To wind up the calendar 25 using this calendar winding device, first operate the air suction pump 43 to suck air from the air suction hole 39 of the winding rod 3 to wind the end of the calendar 25. After adhering to the attachment rod 3, the electric motor 5 is operated to rotate the winding rod 3 and wind up the calendar 25.

Thereafter, by stopping the air suction pump 43, air suction is stopped and the calendar 2
5 in the axial direction of the winding rod 3 and remove it.

As described above, the calendar winding device of the present invention winds and rolls the calendar around a winding rod rotated by an electric motor, so that the winding can always have the same diameter and can be easily inserted into a plastic bag. Also, since an electric motor is used, the calendar can be rolled up very quickly, improving work efficiency.
