Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a self-winding device for a timepiece, and more particularly to a device suitable for screwing a mechanical self-winding timepiece.

[0002]

[Prior art]

 At present, a so-called quartz clock using a crystal oscillator is frequently used as a wristwatch. However, recently, mechanical watches with complicated mechanical mechanisms have been revived, and in particular, 200,000 to 300,000 mechanical luxury wrist watches with a price of 100,000 yen or more each are sold. Such phenomena may be due to various reasons, such as a kind of repellent phenomenon to the extreme digitization of various products including watches, or a self-assertion and, in some cases, a kind of status display. Watch sales are increasing.

[0003] Most of such mechanical watches have a rotating weight stored in the timepiece, and when the timepiece is worn, the weight rotates to automatically wind the mainspring (screw). It is often a so-called self-winding watch. Unless the self-winding operation is performed, the maximum operation time of a self-winding watch is limited to 48 hours. If the watch is left unattended, the watch will stop. For example, if the clock is left unattended because Saturday and Sunday are holidays, the clock will stop when the clock is used again on Monday, even if the mainspring is completely wound before leaving. That is, at this point, the troublesome time adjustment of the clock must be performed.

[0004]

[Problems to be solved by the invention]

 In order to solve the above-mentioned problem, a small number of apparatuses for automatically winding a mainspring by storing a timepiece in a rotating body and rotating the rotating body by a driving means such as a motor have been provided. This device stores a self-winding watch in a container that is rotated by driving means such as a motor via a gear mechanism and performs automatic winding by rotating this container, but the mechanism is complicated. In addition, since there is only one container, it is not possible to automatically wind multiple watches simultaneously.

[0005] After all, the conventional automatic winding device has a large meaning as a decorative storage means, is complicated and expensive, and is accepted only by a very small number of limited purchasers. That is the fact.

[0006]

[Means for Solving the Problems]

 The present invention is an apparatus configured in view of the above-described problems, and includes a drum that is a rotating body that stores a timepiece and a mechanism that rotationally drives the drum, and a mechanism that rotationally drives the drum has a plurality of mechanisms. A means for rotating the drums is provided, and the drums are configured so that they can be appropriately attached to and detached from the mechanism, and the user can appropriately arrange and rotate the respective drums in accordance with the number of watches to be wound. It is a device that is configured so that the clock can be taken in and out of the drum and the drum taken out from the rotary drive means can be taken out and put in.

[0007]

[Embodiment of the invention]

 The driving mechanism is provided with driving means such as an electric motor and a driving roller which is rotationally driven by the driving means. In addition to the driving roller, a plurality of driven rollers that rotate freely or rollers that rotate in synchronization with the driving roller by a transmission means such as a belt are arranged so that their rotation axes are parallel.

On the other hand, a container for storing a timepiece is configured as a drum formed in a cylindrical shape, and stores a timepiece that winds a screw around the drum. By arranging these drums between the driving roller or driven roller arranged in parallel, each drum is supported by two adjacent rollers.

When the driving roller is rotated in the above state, in a configuration having a driven roller that rotates freely, the rotational force of the driving roller is transmitted to the other driven roller via the drum, and the drum rotates. When all the rollers supporting the drums are driven rollers, the driven rollers rotate by the rotation of the adjacent drum, and the driven rollers also rotate via the respective drums. The clock stored in the drum is automatically wound by the rotation of the drum.

In a mechanism having a power transmission means such as a belt, the power is transmitted to all the rollers via the driving force transmission means. In the drive mechanism of this configuration, any roller is driven to rotate, so that the position of the drum can be freely set, and the drum can be rotated regardless of the position of the roller.

[0011]

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 to 3 show a first embodiment of the present invention. In the figure, reference numeral 1 denotes a driving roller, and reference numerals 2, 3 and 4 denote driven rollers, all of which are arranged at equal intervals so that their rotation axes are parallel. Reference numerals 5a and 5b denote frames supporting these rollers 1-4. M1 is an electric motor connected to the drive roller 1, and for example, a small motor driven by a dry battery is sufficient. Although the motor M1 and the drive roller 1 are directly connected in the illustrated configuration, they may be connected via a speed reduction mechanism. In this manner, the drum rotating mechanism is constituted by the driving source such as the driving roller 1, the driven rollers 2 to 4 and the motor 11 for driving the driving roller to rotate.

On the other hand, reference numeral 6 denotes a drum as a container for storing a timepiece, which is formed independently of the drum rotating mechanism. The inner diameter of the drum is set to a size suitable for storing the timepiece W as shown in FIG. Flanges 6a and 6b are formed at both end edges of the drum 6, and are particularly configured to prevent the drum 6 from deviating from each roller when the drum rotates. The drum 6 configured as described above is removably disposed between the respective rollers of the drum driving mechanism.

In the above configuration, when the driving roller 1 is rotated in the X direction, for example, by the motor M1, this rotational force is transmitted to the drum 6A in contact with the driving roller 1, and the drum 6A rotates in the Y direction. This rotation is transmitted to the next driven roller 2, and the driven roller 2 rotates in the same X direction as the driving roller 1, and the rotation of the driven roller 2 causes the adjacent second drum 6B to be the same as the drum 6A. Rotate in the Y direction. In this way, each drum 6 rotates in the Y direction, and the clock stored in the drum 6 winds the mainspring by this rotation.

The drive roller 1 may be rotated by manually operating a power switch connected to the motor M 1, or may be appropriately driven using a timer. Even when the timepiece is not used for a relatively long time, it is also possible to configure to wind the screw periodically by operating the drum rotating mechanism for every two hours, for example, every 24 hours.

The driving source for driving the driving roller 1 to rotate does not need to be limited to an electric motor. For example, the driving source may be of a mainspring type, or a crank or a handle may be provided at one end of the shaft of the driving roller 1 to provide a little play feeling. It is also possible to manually rotate the crank or the handle.

FIG. 4 and FIG. 5 show a second embodiment. In the figure, reference numeral 7A denotes a first driving roller, 7B denotes a second driving roller, 7C denotes a third driving roller, and 7D denotes a fourth driving roller. Each of the illustrated rollers has a configuration in which roller portions 7b and 7c for supporting a drum are disposed at both ends of a shaft 7a, and the entire shaft 7a and roller portions 7b and 7c are referred to as drive rollers. The configuration of the driving roller may be a configuration in which the roller portion is formed on the entire shaft as in the first embodiment, in addition to the configuration shown in the drawing.

The shaft 7a of each drive roller is supported by frames 8a and 8b erected on a base 9. A pulley 10 is attached to each of the shafts 7a protruding toward the frame 8a, and a belt 11 is disposed between the pulleys 10 as power transmission means.

Reference numeral M2 denotes a geared motor as a drive source. When the pulley 13 of the geared motor M2 and the pulley 10 of the adjacent first drive roller are connected to the belt 11, the respective drive rollers 7A to 7D In response to the rotation of the geared motor M2, for example, it rotates synchronously in the X direction. Each drum 6 is appropriately arranged between these drive rollers 7A to 7D.

In this embodiment, since each roller is driven to rotate and the drum 6 does not serve as a transmitting means of the rotational force unlike the first embodiment, the number of the drums 6 and the position of the drum 6 with respect to the drum rotating mechanism are both different. You can choose freely. That is, in the first embodiment, all the driven rollers after the roller 2 are completely free-rotating, and each driven roller is configured to transmit the rotational force via the drum 6 disposed therebetween. On the other hand, in the case of the present embodiment, since the rotational force is transmitted in advance to all the rollers via the power transmission means, the drum 6 rotates regardless of the arrangement position of the drum 6. .

On the other hand, in the case of the first embodiment, the drum driving mechanism can be simply configured, but when three drums 6A, 6B, 6C are arranged as shown in the figure, for example, 6A Is removed, the rotational force is no longer transmitted to the driven roller 2, and the drums 6B and 6C cannot rotate. Similarly, when the drum 6B is removed, the drum 6C cannot be rotated, so that the arrangement position of the drum 6 is naturally determined.

[0021]

[Effect of the invention]

 As described above, according to the present invention, the drum for storing the timepiece and the drum rotating mechanism for rotating the drum are separately configured, and the drum can be appropriately attached to and detached from the drum rotating mechanism. It is easy to put the watch in and out, and it is also possible to store this drum as a storage container for the watch separately from the drum rotation mechanism.

Further, the number of arranged drums can be appropriately selected according to the number of installed rollers of the drum rotating mechanism, and winding of a plurality of watches can be performed simultaneously.
