2. Description of the Related Art Conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 64-64948, front and rear opposing front winders arranged longitudinally and horizontally in the longitudinal direction of a strip-shaped sheet are conventionally used. There is a type in which a split sheet is alternately sorted and wound by a slitter to a take-up device and a rear take-up device. In this sheet split winding device, the front winding device and the rear winding device respectively include a core supporting device and a core supporting device that are parallel to the longitudinal direction of the core according to the length of the core. An interval adjustment table is provided, which can be slid in the front-rear direction, and the take-up rolls of the divided sheets are carried out to the machine side by conveyors provided between the touch roller section and each take-up device.

[0003] Further, as disclosed in Japanese Patent Application Laid-Open No. 4-303352, for example,
A spacing adjustment table is installed rotatably in two stages vertically and horizontally in parallel with the width direction of the belt-shaped sheet, and the core support device is attached to the upper spacing adjustment table in a suspended state, and the lower spacing adjustment table is attached to the lower spacing adjustment table. In some cases, the core supporting device is mounted in an inverted state. In this apparatus, in order to carry out a take-up roll, there is provided a product take-out device in which an upper receiving member and a lower receiving member are lifted and lowered and rotatably attached to a lift truck. Then, to unwind the take-up roll, rotate the take-up roll to the unloading position in front by rotating the winding core supporting device together with the interval adjusting table, and then move the product unloading device to the unloading position, and The lower take-up device supports the upper and lower take-up rolls from below, and in that state, moves the product take-out device to a position such as a conveyor, and transfers the take-up rolls to the conveyor.

[0004]

The above-described sheet winding device in which the winding devices are arranged before and after is generally used in the sheet winding process in which the width of the raw material exceeds 4 meters. However, if the web width is small, for example, about 4 meters or less, the length in the front-rear direction is long for the narrow web width, and a large installation area is required.

[0005] The above-described sheet split winding device having a product take-up device in which a take-up device is provided above and below, and an upper and lower receiving device is attached to a lift truck, has the following problems.
That is, the height of the product take-out device is high and large, and the occupied space is large. Since the moving space is required, the entire sheet dividing and winding apparatus including the unloading device requires a large installation area. In addition, when the take-up roll is carried out, the product take-out device moves to the take-up preparation work space in front of the upper and lower take-up devices and receives the take-up roll, which is disadvantageous in securing the safety of the operator. The next winding preparation operation cannot be performed until the apparatus has completely left the winding preparation work space. In general, the interval adjusting table is equipped with a plurality of pairs of core supporting devices. When the number of divisions of the belt-shaped sheet is small, some of the core supporting devices are stopped, and they are put on standby on both sides of the interval adjusting table. Therefore, the length of the interval adjusting table is made longer than that of the belt-shaped sheet guide roller in consideration of the standby position of the core supporting device. Therefore, in order to rotatably support the gap adjusting table, tall machine frames are required at both ends thereof, and the size of the apparatus is increased.

SUMMARY OF THE INVENTION In view of the above problems, the present invention requires a small installation area, does not require unloading the take-up roll by the labor of the operator, and can ensure the safety of the worker when unwinding the take-up roll.

Then, the lower unloading device 51 moves up the belt conveyor 36 by the elevating device 37 at the lower unloading position and receives the take-up roll R2 from the lower core support device 26 onto the conveyor 36. When the lower core support device 26 releases the winding roll R2, the moving mechanism 24
Operates, and the lower interval adjusting table 15 starts retreating to the retracted position shown by the solid line. At the same time, each lifting / lowering device 37 operates to lower each belt conveyor 36 to a predetermined carry-out height. This state is shown by a solid line in FIG. Then, in this state, the belt conveyor 36 operates to take up the winding roll R.

According to the sheet dividing and winding apparatus according to the first aspect, the divided sheets are sorted and wound up and down, and are moved from the retracted position below the lower touch roller to the slitter side of the lower interval adjusting table. Since the upper and lower take-up rolls are unloaded by the unloading device movably disposed to the lower unloading position, the installation area can be reduced. Also, the upper core is supported at the lower end of the upper core support device, and the lower core is supported at the tip protruding toward the touch roller side of the lower core support device. After receiving the take-up roll on the conveyor from the lower core support device and carrying it out, the lower take-up roll was carried out by receiving and taking out the take-up roll from the upper core support device on the conveyor. Thereafter, the unloading device moves up the conveyor without moving from the unloading position, and is ready to receive the take-up roll from the upper core support device.
Therefore, the upper and lower winding rolls can be efficiently unloaded by one unloading device. Also, even if the worker does not move to the front and rear winding positions as in the conventional case, the cores are mounted on the upper and lower core supporting devices from the work floor, and the leading ends of the divided sheets are stopped on the cores. The winding preparation operation can be performed efficiently. In addition, since there is no core supporting device before the slitter, the workability of the positioning operation is good. Further, a working floor is provided on the front side of the lower core supporting device, and the upper and lower winding rolls can be transported to the machine side by a conveyor on the slitter side of the lower core supporting device, so that the winding roll There is no danger to workers when unloading.

According to the sheet dividing and winding apparatus of the present invention, the upper and lower winding rolls can be unloaded simultaneously by the respective conveyors, so that the unloading time of the upper and lower winding rolls can be reduced. it can. In addition, since the upper carry-out device is disposed on the slitter side of the lower carry-out device, the sliding distance of the upper interval adjusting table can be reduced, and the structure of the upper winding portion does not become large.
