Description

[Detailed Description of the Invention] This invention relates to a winding device that divides a belt-like sheet into a plurality of strips using a slitter and winds it up and down the upper and lower winding shafts, and swings the upper and lower touch roller support arms as the winding progresses.

The present applicant previously filed a patent application No. 58-22037 for ``Upper-lower distribution winding device''. In the first aspect of the present invention, fixed gears provided on the swing shafts of the upper and lower touch roller support arms are meshed with each other to offset the weight of the upper and lower swing support arms. As a result, the influence of the weight of the vertically swinging support arm on touch pressure control can be eliminated.

However, in the above case, both support arms are always constrained to move symmetrically.

Therefore, the present invention provides a split winding device of this type, which includes an upper touch roller that presses the sheet from above or from the side of the upper winding shaft, an upper swinging support arm that supports the upper touch roller, and the lower winding shaft. A lower touch roller that presses the sheet from below or from the side, a lower swing support arm that supports the lower touch roller, and an upper swing shaft and a lower swing that are fixed to the swing centers of both swing support arms, respectively. a rotating shaft; a gear fixed to one of the upper swing shaft or the lower swing shaft;
a fixed position gear rotatably provided on the same axis as the gear; a floating composite gear having a gear with a different number of teeth meshing with the two gears; a differential gear mechanism comprising a movable frame that rotatably supports a floating compound gear; and a transmission that transmits rotation of the fixed position gear to the other of the upper swing shaft or the lower swing shaft. It is characterized by comprising a mechanism.

Therefore, according to the present invention, the rotation of the gear provided on one of the upper swing shaft and the lower swing shaft is controlled by the rotation of the gear provided on the movable frame that is rotatable about the axis. , an idling compound gear having a different number of teeth meshing with the gear and a fixed position gear rotatably provided on the same axis as the gear, the rotation of the fixed position gear and the fixed position gear being controlled by the other swing axis; Since the transmission is transmitted to the other swing shaft through a transmission mechanism that transmits the signal to the other swing shaft, it is possible to offset the weight while allowing the uneven movement of both swing support arms through the differential gear mechanism. In each case, contact pressure can be controlled individually by attaching a drive mechanism (hydraulic cylinder) for direct or indirect driving.

Next, the configuration and embodiments of this invention will be explained with reference to the drawings.

FIG. 1 is the same as the explanatory diagram of the first invention of Japanese Patent Application No. 58-22037 mentioned above, in which 1 is the original fabric, S is the pulled out strip sheet, 2 is the slitter, 3, 3
a is an upper and lower winding shaft that is rotationally driven at a fixed position;
4, 4a are the upper and lower touch rollers, 5, 5a are the respective swing support arms, and 6, 6a are the swing support arms 5, 5.
A guide roller for the sheet S is attached to each of the pivot shafts 6, 6a, and upper and lower gears 7, which are locked with a key, are attached to the pivot shafts 6 and 6a. 7a is attached to each. Each of the swing support arms 5, 5a is provided with a touch pressure control fluid pressure cylinder 8, 8a, respectively.

Now, in the present invention, as described above, the upper gear 7 and the lower gear 7a are not directly engaged with each other, but the differential gear mechanism 10 intervenes as shown in FIG. 2 and below. Examples of this part are shown in FIGS. 2 and 3. In FIG. 2, fixed gears 7, 7a are fixedly provided at the pivot centers of the bases of both swing support arms and are provided on rotatable swing shafts 6, 6a.
It looks like they are interlocking with each other, but as you can see in Figure 3,
The two gears mentioned above do not mesh with each other. That is, the upper gear 7 as a transmission mechanism meshes with a fixed position gear 11 provided coaxially with the lower swing shaft 6a in the differential gear mechanism 10, and the fixed position gear 11 engages with the lower swing shaft 6a.
It meshes with one gear 12a of a floating composite gear 12 that is pivotally supported on a movable frame 9 that is rotatable about an axis. Further, the other gear 12a of the floating composite gear
is meshed with a lower gear 7a as a differential gear mechanism. In order to attach the differential gear mechanism 10, a bracket 15 is attached to the vertical wall 14 of the movable frame 9, and the fixed position gear 11 is connected to the swing shaft 6 of the lower touch roller.
It is fitted via a ball bearing to a fixed shaft 13 that shares an axis with a, and rotates with play. The fixed shaft 13 supports the movable frame 9 together with the swing shaft 6a via ball bearings, and also serves as a rotation shaft for the movable frame 9.

The number of teeth of the gears in this embodiment is 36, the same number for gears 7 and 11, and 20 and 21 for gears 12a and 12b, respectively.
The gear 7a is 35.

Sheet roll S being wound on the upper and lower winding shafts 3, 3a ₀
If the diameters of the upper and lower touch rollers are different, the opening angles of the swinging support arm 5 of the upper touch roller and the swinging support arm 5a of the lower touch roller will be different accordingly. For example, the third
The lower swing shaft 6a in the figure does not rotate and the upper swing shaft 6
If it turns a little, the gears 7, 11, and 12 will turn a little and the gear 7a will not turn. That is, the rotation angle of the gear 7a becomes zero, and a small amount of the rotation angle of the gear 7 is absorbed by the movement of the movable frame 9.

In this way, the difference in opening angle between the upper and lower support arms 5, 5a is absorbed, and there is no problem at all with the weight offset effect.
The upper and lower touch rollers 4, 4a contact the sheet roll _S0 with only the required touch pressure from the fluid pressure cylinders 8, 8a, and since there is no adverse effect due to the difference in diameter of the upper and lower sheet rolls _S0 , touch pressure control is performed individually. It is.

Although this invention has been explained above using one example, it is natural that this invention may be modified and applied as appropriate depending on the well-known technology of the designer who implements it. The structure is left to the designer as long as it has the original function of a differential gear that can compensate for any unevenness in the rotation of the gears 7 and 7a by the movement of the floating compound gear. That is, since the difference in swing angle between the swing support arms 5 and 5a of the upper and lower touch rollers is a very small angle, it is only necessary to have a function to absorb this difference. Therefore, the gear of the differential gear mechanism provided at the rotation center of the movable frame and the floating composite gear can also be indirectly engaged with each other. The fluid pressure cylinder shown as a drive mechanism that drives the upper and lower swinging support arms to press the touch roller against each winding shaft may be replaced with a mechanical drive mechanism, one of which is a differential gear mechanism as a transmission mechanism. The swing support arm may be indirectly driven by driving the movable frame.

According to this invention, it is possible to tolerate variations in the swinging angles of the vertically swinging support arms, and it is also possible to individually control the winding of the upper and lower sheets by touch pressure.
