Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a laminating apparatus for covering the front and back of cards, documents, etc. with a synthetic resin film, and in particular, frequency switching that can be applied by selecting two types of commercial frequencies. Type laminating apparatus.

[Conventional technology]

Since commercial power in Japan is divided into regions with frequencies of 50 Hz and 60 Hz, electrical equipment that uses motors is manufactured with a structure corresponding to each frequency range.
These are sold separately. This is not an exception even in a laminating apparatus belonging to office equipment, and gears of a power transmission mechanism are selected and incorporated according to the frequency of the sales area. Also, in a laminating apparatus of a type that has a relatively simple structure and is inexpensive,
There is also a system in which a power transmission mechanism is set in accordance with an intermediate value of both frequencies to be used for both frequency ranges.

[Problems to be solved by the device]

However, in the gear selection type laminating device, there is a problem that flexibility in each frequency range is not preferable, and in the both frequency dual type laminating device, setting of the power transmission mechanism is not possible. Since it is an intermediate value, the rotation speed of the roller is not optimum regardless of the frequency used.

On the other hand, in order to solve these problems, it is possible to mount a frequency converter and to obtain the rotation speed of the roller corresponding to the commercial frequency of the area, but according to this means, This is not preferable because the electric circuit becomes complicated and a structure for reducing the influence of heat on the circuit is required, which causes an increase in cost.

The present invention has been made in view of such circumstances, and it is possible to always obtain the same roller rotation speed even if the commercial frequency is changed, and the structure and operation are simple and the cost is not increased. The purpose is to provide a device.

[Means for Solving the Problems]

In the laminating apparatus of the present invention, the driven gear that meshes with the drive gear connected to the motor is rotatably supported by the switching lever that pivots around the rotation center of the drive gear and is movable.

On the movement locus of this driven gear, an inlet side gear that drives the inlet side roller and an outlet side gear that drives the outlet side roller are arranged, and the driven gear is selected as both the inlet side and outlet side gears. It is configured to be able to mesh with each other. The tooth number ratio between the inlet side gear and the outlet side gear corresponds to the ratio between the first frequency and the second frequency higher than this, among commercial frequencies,
Regardless of whether the driven gear meshes with the gear on the inlet side or the outlet side, the rollers on the inlet side and the outlet side have the same rotation speed.

Further, the inlet side roller and the outlet side roller are connected by a transmission mechanism of a constant speed and the same rotation direction.

[Action]

When the switching lever is turned in accordance with the commercial frequency of the area where the laminating device is used, the driven gear moves and meshes with either the inlet side gear or the outlet side gear, which causes the inlet side roller and the outlet side roller. The roller on the meshed side among the above rotates at a predetermined rotation speed. Then, the transmission mechanism causes the rollers on the other side to rotate in the same direction at the same number of rotations, and eventually both the rollers on the inlet side and the outlet side rotate at a predetermined number of rotations, so that a smooth laminating operation can be performed.

Also, when using this in an area where the commercial frequency is different, when the switching lever is turned to the other, the driven gear meshes with the gear on the opposite side to rotate the roller corresponding to that gear, Further, the other roller is also rotated in the same direction at the same rotation speed by the transmission mechanism. The rotation of the rollers at this time is the same as the rotation speed before the switching in consideration of the gear tooth ratio, so that the rollers rotate at the same rotation speed even in regions where the commercial frequency is different. Therefore, the finish is uniform in any area.

〔Example〕

1 and 2 show a power transmission mechanism in which rollers are omitted. Reference numeral 1 denotes a motor, which is fixed to and supported by a bracket 10, and a drive gear 3 is fixed to an output shaft 2 thereof. A switching lever 4 is rotatably supported on the output shaft 2 about the center line of the output shaft 2 and the drive gear 3, and the driven gear 5 is driven by the switching gear 4.
It is supported in the state of meshing with. Thus, the driven gear 5 is kept in mesh with the drive gear 3 and is movable around the drive gear 3 by the switching lever 4.

The inlet side gear 6 and the outlet side lower gear 7 are arranged on the locus of the movement of the driven gear 5, and the driven gear 5 is connected to the inlet side gear 6.
And the lower gear 7 on the outlet side can be selectively meshed with each other.

The inlet gear 6 is fixed to the rotating shaft 8 and the outlet gear 7
Is fixed to a rotating shaft 9, an inlet side lower roller 11 is fixed to the rotating shaft 8, and an outlet side lower roller 12 is fixed to the rotating shaft 9 at the center of the shaft as shown in FIG.
The upper roller 1 on the inlet side is located above the lower roller 11 on the inlet side.
3, Outlet-side upper rollers 14 are arranged above the outlet-side lower rollers 12 in rolling contact with each other. Reference numeral 15 denotes a rotating shaft to which the outlet-side upper roller 14 is fixed, and an outlet-side upper gear 16 fixed to an end of the rotating shaft meshes with the outlet-side lower gear 7 to rotate the outlet-side lower gear 7. The outlet side upper roller 14 is driven by the above.

Here, the inlet-side lower roller 11 and the outlet-side lower roller 1
2. The outlet side upper roller 14 is positioned and supported by the bearing plates 17 and 18 via the rotating shafts 8, 9 and 15, and the inlet side upper roller 13 has a larger weight than the other rollers. The shaft 19 penetrates through a vertically elongated long hole 17a formed in the bearing plates 17 and 18, and is in rolling contact with the inlet-side lower roller 11 by its own weight.

Further, the transmission gears 19, 2 are provided at the other ends of the rotary shafts 8 and 9.
1 is fixed, and the bearing plate 1 is provided between the transmission gears 19 and 21.
An idler gear 22 rotatably supported by 8 interposes with the idler gear 22 to form a transmission mechanism 23 for transmitting a rotational force between the rotary shafts 8 and 9. This transmission mechanism 23 transmits the rotational driving force between the inlet-side lower roller 11 and the outlet-side lower roller 12 at a constant speed and in the same rotation direction.

Each of the above components is arranged in the casing 24, and 25 indicates its inlet and 26 indicates its outlet. Casing 24
4, a hole 24a shown in FIG. 4 is formed at the tip end position of the switching lever 4, and a stopper 27 is inserted therein. The stopper 27 fixes the position of the switching lever 4, and fixes the switching lever 4 at a position where the driven gear 5 individually engages with the inlet-side lower gear 6 and the outlet-side lower gear 7. is there. Therefore, the stopper 27
A protrusion 27a is formed on the projection 27a, and the protrusion 27a abuts the switching lever 4 to prevent the movement thereof. The stopper 27 has such a shape that it can be used regardless of whether the driven gear 5 is meshed with either of the gears 6 and 7, and the proper use is made by reversing the left and right in FIG.

The tooth number ratio of the inlet-side lower gear 6 and the outlet-side lower gear 7 corresponds to the ratio of two types of frequencies of commercial electric power. Since commercial power in Japan is 50Hz and 60Hz, for example, 50Hz
When the driven gear 5 is meshed with the outlet lower gear 7, the driven gear 5 is meshed with the inlet lower gear 6 at 60 Hz, the number of teeth of the outlet lower gear 7 and the inlet lower gear 7 The fraction of 6 is 5 to 6. The outlet-side lower gear 7 and the outlet-side upper gear 16 have the same tooth number ratio, and the transmission gear 19 and the transmission gear 21 have the same tooth number ratio.

Next, the operation of this embodiment will be described.

First, the switching lever 4 is moved to the outlet side lower gear 7 side in accordance with the frequency of commercial power in the usage region, for example, in the 50 Hz region in the Kanto region, and the switching lever shown in FIG. 1 and shown by the solid line in FIG. Position 4. At this time,
Remove the stopper 25 from the casing 24
The tip of a tool such as a screwdriver is inserted from a, and this is engaged with the concave portion of the tip of the switching lever 4 to move the switching lever 4. As a result, the driven gear 5 meshes with the lower gear 7 on the outlet side, so that the stopper 27 is mounted in the hole 24a and the switching lever 4 is fixed in that position.

When the motor 1 is rotated here, the drive gear 3 rotates via the output shaft 2, and this rotates the outlet side lower gear 7 via the driven gear 5. Then, the outlet-side upper roller 14 rotates via the outlet-side upper gear 16 meshing with the outlet-side lower gear 7 and the rotating shaft 15, while the outlet-side lower roller 12 also rotates via the rotating shaft 9. The rotation of the rotary shaft 9 is transmitted to the rotary shaft 8 via the transmission gears 21, 22, 19 of the transmission mechanism 23 to rotate the inlet-side lower roller 11, and the rotation also rotates the inlet-side upper roller 13. It will be. Thus, since the rollers 11, 12, 13, 14 rotate in a predetermined manner, the laminated product inserted from the inlet 25 into the casing 24 has the upper and lower rollers 1 on the inlet side.
In addition, the rollers 11 and 13 are drawn in by 1, 13 and heated and pressure-bonded by the rollers 11 and 13 that are heated by a heating device (not shown), and are sent to the upper and lower rollers 12 and 14 on the outlet side. Sent out.

Next, for example, in the 60 Hz region in the Kansai region, the switching lever 4 is moved to the entrance side lower gear 6 side to the position of the switching lever 4 shown in FIG. 2 and shown by the chain line in FIG. The stopper 27 at this time is reversed to the left and right in FIG. As a result, the rotational force of the drive gear 3 is transmitted to the inlet-side lower gear 6 via the driven gear 5,
While rotating the inlet-side lower roller 11 via the rotating shaft 8, the transmission mechanism 23 is transmitted in the opposite manner to rotate the outlet-side lower roller 12 via the rotating shaft 9 and the outlet-side lower gear 7. The outlet-side upper roller 14 is rotated via the outlet-side upper gear 16 and the rotating shaft 15.

At this frequency of 60 Hz, the number of rotations of the motor is higher than that at the time of 50 Hz, but the number of teeth of the inlet side lower gear 6 is also larger than the number of teeth of the outlet side lower gear 7, so each roller 11
The rotation speeds of -14 are the same as those at 50 Hz. For this reason, the passing speed of the laminated product moved by these rolls is always the same, so that the heat quantity of the heating device (not shown) can always be the same, and the adjustment is not necessary.

Thus, it is the transmission path from the motor 1 to the driven gear 5 that changes in rotation speed according to the frequency of the commercial power,
The rotation speed is always the same in the transmission path after the outlet side lower gear 7 and the inlet side lower gear 6 where the driven gear 5 meshes.

In addition, the number of teeth of the inlet side lower gear 6 and the outlet side lower gear 7 is reversed, and the driven gear 5 is set to the inlet side lower gear 6 at 50 Hz.
Of course, the frequency is not limited to the above 50 Hz and 60 Hz, and other frequencies may be applied depending on the area where the laminating apparatus is used. Of course, you get it. Further, the gear with which the driven gear 5 meshes may be a gear that rotates integrally with the upper roll of the pair of upper and lower rollers.

[Effect of device]

As described above, in the present invention, the same roller rotation speed can always be obtained even by changing the frequency of the commercial electric power, simply by operating the switching lever. Moreover,
Since it is possible to maintain the same number of rotations of the roller due to the change of the frequency only by moving the driven gear, there is an effect that the structure can be prevented from becoming complicated.
