Problems to be solved by the invention

[0003] However, if it is necessary to hang the hanging shaft in a short time while exerting force, there is no time to gradually lower the hanging shaft, so it is not possible to work carefully. For this reason, when it is necessary to hang the hanging shaft in a short time, the hanging shaft may be lowered at a stretch and spread. In this case, the tension is applied to the part of the paper on which the characters and pictures are drawn (the main body of the hanging shaft), which may damage the hanging shaft body. Also, at the moment when the hanging shaft spreads, it may come off from the hanging strap force hook and the hanging shaft may fall. Furthermore, since the weight of the hanging shaft concentrates on the hanging strap, the hanging strap may be cut.

The hanging shaft 101 is housed by winding a hanging shaft main body 105 around the outer peripheral surface of the shaft rod 102.

Returning to FIG. 1 and FIG. 2, the description will be continued. The base portion 11 is a box-like shape at the base of the hanging shaft support device 1, and a second pulley 43, a stepping motor 45 as a drive device, a drive control device 46, and the like are provided inside the base portion 11. ing. Further, a setter 13 for placing the hanging shaft 101 is erected on the upper surface portion 12 of the base portion 11. Since the central portion of the hanging shaft 101 placed on the setter 13 is located substantially in front of the support column 21, it is easy to hang the hanging strap 104 on the hook 31! /.

[0024] Further, inside the base portion 11, there is a concave portion 14 for taking in and out the hanging shaft 101 placed on the setter 13 inside the transparent wall 61. On the upper side of the front part 15 of the base part 11, there is a recess. A lid 16 for inserting and removing the hanging shaft 101 through 14 is provided via a hinge 19. The lid portion 16 includes a lid body 17 and a handle 18 attached to the upper end of the lid body 17. When the handle 18 is pulled in the front direction, the lid portion 16 is bent in the front direction.

Further, an input device 49 for inputting a predetermined numerical value by a pressing operation is provided below the front surface portion 15 of the base portion 11.

That is, the stepping motor 45 is rotationally driven, the second pulley 43 is rotationally driven, and the chain 44 is also rotationally driven. As the chain 44 is driven to rotate, the hook 31 attached to the chain 44 moves up and down.

[0031] The transparent wall 61 is formed of a transparent material such as an acrylic plate or a glass plate, and protects the hanging shaft 101 from a gust of wind or a child's mischief. [Electric configuration of hanging shaft support device]

Next, the control circuit of the hanging shaft support device 1 will be described in detail. FIG. 5 is a block diagram showing a control circuit of the hanging shaft support device 1 in the present embodiment.

[0033] Based on the numerical value input by the input device 49, the drive control device 46 that controls the stepping motor 45 includes a CPU (central processing unit) 91, a ROM (read-only memory) 92, and a RAM (read-write memory). ) It has 93 mag. The CPU 91 is connected to the ROM 92 and the RAM 93, and executes various processes according to programs stored in the ROM 92.

The drive control device 46 is connected to the input device 49 and further connected to the stepping motor 45 via the motor drive control circuit 94.

The ROM 92 stores a program for controlling the stepping motor 45 by the CPU 91. For example, after the stepping motor 45 is driven at a predetermined speed, the stepping motor 45 is gradually decelerated, and the midpoint force between the setters 13 and 13 of the base portion 11 and the height to the hook 31 are input to the input device 49. The ROM 92 stores a program for stopping the driving of the stepping motor 45 when the numerical value is the same.

Note that in this embodiment, ROM 9 is used as a medium for storing programs, tables, and the like.

However, the present invention is not limited to this as long as it is a computer-readable storage medium.

The RAM 93 stores various variable values as a temporary storage area of the CPU 91. For example, data relating to a predetermined numerical value input by the input device 49 (see FIG. 1) is stored.

The motor drive control circuit 94 generates a pulse wave on the basis of predetermined data or a predetermined command transmitted from the CPU 91, and drives and controls the stepping motor 45.

[0039] The input device 49 will be described with reference to FIG. FIG. 6 is an enlarged view of the input device 49. The input device 49 includes a numeric key 81 for inputting 0 to 9 and a decimal point, a display board 82 for displaying a number input by the number key 81, a clear one key 83 for erasing the number input by the number key 81, A fine adjustment key 84 and an enter key 85 for finely adjusting the numerical value displayed on the display panel 82 up and down are provided. The enter key 85 transmits data for starting operation to the drive control device 46 when pressed. [0040] The processing executed by the hanging shaft support device 1 is as follows. When a predetermined numerical value is input to the input device 49, the input device 49 transmits data of the predetermined numerical value to the drive control device 46. The RAM 93 receives and stores predetermined numerical data. Further, when the enter key 85 of the input device 49 is pressed, the input device 49 transmits a drive start signal to the drive control device 46. Then, the CPU 91 reads out the program stored in the ROM 92, refers to the predetermined numerical data and the drive start signal stored in the RAM 93 according to the program for controlling the stepping motor 45, and determines the drive start command and The predetermined numerical data and the driving speed data of the stepping motor 45 are transmitted to the motor drive control circuit 94. The motor drive control circuit 94 receives these drive start commands, predetermined numerical data, and drive speed data of the stepping motor 45, generates a pulse wave based on these data, and drives the stepping motor 45.

[0041] Then, the stepping motor 45 is driven to rotate at a predetermined speed, and then gradually starts to decelerate at a predetermined time point. The midpoint force between the setters 13 and 13 of the base portion 11 is also as high as the hook 31. When it becomes the same as the predetermined numerical value input to the input device 49, the drive is stopped.

That is, since the CPU 91 rotates the stepping motor 45 at a predetermined speed, the second pulley 43 is driven to rotate at a predetermined speed. Therefore, the speed at which the hanging shaft 101 is lifted becomes constant, and it is possible to prevent a strong tension from acting on the hanging shaft 101 main body partially. For this reason, damage to the hanging shaft 101 that occurs when the hanging shaft 101 is decorated can be prevented.

[0043] Further, the CPU 91 drives the stepping motor 45 when the height from the midpoint between the setters 13 and 13 of the base portion 11 to the hook 31 becomes the same as a predetermined value input to the input device 49. Therefore, when the height force from the base portion 11 to the hook 31 reaches a predetermined numerical value input to the input device 49, the rotational drive of the second pulley 43 is stopped. Therefore, since the height at which the hanging shaft 101 is lifted can be arbitrarily set according to the input predetermined numerical value, fine adjustment of the height after the hanging shaft 101 is lifted can be omitted.

[0044] Since the CPU 91 stops the driving of the stepping motor 45 by gradually decelerating the stepping motor 45, the rotational speed of the second pulley 43 also gradually decreases. As a result, the rotational drive of the second pulley is also stopped. Therefore, together with the chain 44 wound around the second pulley 43, the hook 31 attached to the chain 44 gradually decelerates and stops. For this reason, the hanging shaft 101 also gradually decelerates and stops. Therefore, compared to the case where the hanging shaft 101 stops suddenly without being decelerated, the hanging strap 104 of the hanging shaft 101 comes out of the hook 31 when the hanging shaft 101 stops, and the hanging shaft 101 Can be prevented from falling.

In this embodiment, the stepping motor 45 is used as the drive device, but another motor may be used. For example, a DC motor may be used as the drive device.

[0046] [How to use hanging shaft support device]

A method of using the hanging shaft support device 1 including the input device 49 will be described with reference to FIGS. 1, 2, 4, and 6 to 8. FIG. 7 is a perspective view of the hanging shaft support device 1 in which the lid portion 16 is opened in the front direction. FIG. 8 is a perspective view of the hanging shaft support device 1 in which the lid portion 16 is opened forward and the hanging shaft 101 is placed on the setters 13 and 13.

[0047] First, the handle 18 is pulled forward. When the handle 18 is pulled forward, as shown in FIG. 7, the lid 16 opens forward, so that the hanging shaft 101 is inserted through the recess 14 as shown by the arrow A, and the hanging shaft 101 is placed on the setters 13 and 13. Place it (see Figure 8). Hang the hook 104 of the hanging shaft support device 1 on the hook 31 of the hanging shaft 101, pinch the handle 18, and close the lid 16 that has fallen forward. (refer graph1). Next, the numeric key 81 of the input device 49 is pressed to input a predetermined numerical value. The value is displayed on the display panel 82 in units of a predetermined numerical force Scm (see Figure 6). As the predetermined numerical value at this time, the vertical dimension of the hanging shaft 101 (including the hanging string) is input. When the displayed numerical value is confirmed and the enter key 85 is pressed, the stepping motor 45 starts to be driven (see FIG. 4). The stepping motor 45 rotationally drives the second pulley 43, the hook 31 moves upward via the chain 44 wound around the second pulley 43, and the hanging shaft 101 is lifted. When the height from the midpoint between the setters 13 and 13 of the base portion 11 to the hook 31 becomes the same as a predetermined numerical value, the stepping motor 45 stops driving (see FIG. 2).

[0048] In this manner, the hanging shaft 101 is decorated by simply placing the hanging shaft 101 on the setters 13 and 13 of the base portion 11, hooking the hanging string 104 of the hanging shaft 101 on the hook 31, and driving the stepping motor 45. be able to. Therefore, if you have to hang the hanging shaft 101 in a short time Even if the hanging shaft 101 is not damaged, the hanging shaft 101 can be decorated. In addition, since the contact area of a human hand can be reduced, damage to the hanging shaft 101 that occurs when the hanging shaft 101 is decorated can be prevented.

[0049] On the other hand, when storing the hanging shaft 101, when "0" is input to the input device 49 and the enter key 85 is pressed, the stepping motor 45 starts to drive after a while, and the hook 31 is lowered. Come on. Then, both ends of the shaft rod 102 are rotated and the shaft body 105 is wound around the outer periphery of the shaft rod 102 to store the shaft 101. The setters 13 and 13 may be automatic take-up devices and controlled by the drive control device 46 so that the hanging shaft 101 can be stored automatically.

[0050] [Modification]

The first embodiment of the present invention has been described above, but only a specific example is illustrated and the present invention is not particularly limited.

[0051] In this embodiment, as shown in FIG. 1, the length between the sets 13 and 13 for placing the hanging shaft 101 is constant, but the present invention is not limited to this. That is, the setters 13 and 13 may be moved according to the length of the shaft rod 102. Since the length between the setters 13 and 13 can be changed by rubbing such a structure, various types of hanging shafts having different widths can be hung.

Further, in the present embodiment, as shown in FIG. 1, the force by which the setter 13 for placing the hanging shaft 101 is erected on the base portion is not limited to this. In other words, any structure can be used as long as the hanging shaft 101 can be placed. For example, as shown in FIG. 9, a semi-cylindrical recessed portion on which the hanging shaft 101 can be placed on the base portion 11. 20 may be provided.

In the present embodiment, as shown in FIG. 2, the second pulley 43 is attached to the chain 44, and the second pulley 43 is driven to rotate, and the chain 44 is also driven to rotate. However, the present invention is not limited to this. For example, as shown in FIG. 10, the chain 44 may be driven up and down by the hoisting machine 51 connected to the stepping motor 45 so that the chain 44 is hoisted or unwound.

[0054] In the present invention, the third pulley 47 and the fourth pulley 48 (see Fig. 4) are used. In this case, the first pulley 42 and the second pulley 43 are provided so as to face each other.

[0055] Further, in the present invention, any power transmission band can be used as long as it can transmit the driving force of the second pulley 43 connected only by the chain 44, and a belt, a string or the like may be used.

In the present invention, when the lid portion 16 is closed, the space surrounded by the lid portion 16, the transparent wall 61, and the base portion 11 is in a sealed state (see FIG. 1). Therefore, the hanging shaft support device 1 may be equipped with an air conditioning device for replacing the air inside with nitrogen. By providing such an air conditioner, the hanging shaft 101 does not come into contact with oxygen, so that the hanging shaft 101 can be prevented from being deteriorated by acid.

In the present embodiment, the transparent wall 61 and the lid 71 may be omitted as in the hanging shaft support device 111 as shown in FIG.
