Description of the Related Art A slitter is formed by slitting a wide web such as paper or plastic film vertically and winding the slit narrow web into a rolled product, but the ends of the slitter rolled product do not overlap each other. As described above, a device is generally used in which the material is distributed to two winding shafts arranged vertically in two stages at an interval in the vertical direction. By the way, in order to remove the slitter winding product from the slitter device to the outside of the slitter, the support of one end of the winding shaft is removed and the slitter winding product is pulled out in the axial direction to take out the slitter winding product. It is difficult to move the product because the load of the product is heavy on the worker and it is difficult to move the product.The next winding is performed until the extraction work is completed and the work to transport the product out of the slitter device is completed. It has been difficult to improve the operation rate because the slitter has to be stopped for a long time, for example, the work of mounting the paper tube cannot be started.

In order to solve the above-mentioned problems, the applicant has proposed a slitter winding product unloading device in Japanese Patent Application No. 11-32171. This slitter take-up product unloading device moves the carrier to the lower side of each take-up shaft after the winding is completed for the slitter take-up product distributed and wound on the two take-up shafts, and Lift and lower to support the rolled product on the carrier, move the carrier in the direction of the winding shaft, extract the wound product from the winding shaft, carry it out to the end of the winding shaft, wait for standby, and withdraw while The work for mounting the paper tube for the next take-up can be started on the completed take-up shaft, and the stoppage time of the slitter can be greatly reduced to improve the operation rate. However, in order to take out the rolled product supported on the vertically arranged carrier from the vertically arranged winding shaft to the outside of the slitter, the product must be further transferred to the carrier. The total weight of the wound product wound on the spindle is usually 500 kg to 1 ton,
