[Industrial application fields]
The present invention is for vertically stacking a plurality of winding rolls on a pallet.Winding ofThe present invention relates to a vertical roll palletizer.
[0002]
[Prior art]
In a processing facility for a winding roll of a belt-like sheet such as a film or paper, the winding roll is generally transported in a laid state. And when they are shipped, they are often stacked vertically on a pallet. Since this take-up roll is easily damaged, it is not preferable to hold the outer periphery with a device such as a robot hand and stack it vertically on a pallet. Conventionally, as an apparatus for stacking vertically on a pallet so as not to damage the take-up roll, for example, as disclosed in Japanese Patent Laid-Open No. 6-24554, a lying-up take-up roll is placed on a stand that can be inverted. The end of the take-up roll is brought into contact with the movable stopper plate that extends vertically from the upper surface of the stand to the tip of the stand, and the stand is inverted with the stopper so that the take-up roll stands on the movable stopper plate. In some cases, the movable stopper is retracted from the state to the inside of the table so as to be lowered onto the pallet located below the movable stopper. In this device, the transfer position in the horizontal direction of the pallet is changed by a supply device that transfers the take-up roll in the horizontal direction of the table, and the stacking position in the vertical direction of the pallet is transferred to transfer the pallet in the longitudinal direction of the table. Varies depending on the device.
[0003]
Further, in the winding roll processing facility, it is desirable to make a production plan with the highest priority on improving the product yield, and to process the winding roll based on that. In general, a plurality of processed winding rolls are made into a set according to the ordering conditions, and are shipped on a pallet. Therefore, the processing time of each winding roll placed on one pallet varies widely. Therefore, conventionally, the processed winding rolls are sequentially conveyed to a sorting device and sorted and stored for each pallet. When all the pallet-unit take-up rolls are prepared, the pallet-unit take-up rolls are unloaded from the sorting device, sent to the palletizer, and stacked on the pallet by the palletizer (see Japanese Patent Laid-Open No. 5-338741).

Further, when the winding rolls are vertically stacked on the pallet in the above-described procedure, the following problems occur. That is, the take-up roll must be carried to a sorting device and sorted, and the take-up roll stored in the sort device must be taken out and transported to the palletizer on the palletizer and placed on the pallet by the palletizer. Therefore, it takes time to carry in, carry out, and sort into the sorting apparatus. In addition, it is necessary to have a sorting device that can sort and store the winding rolls and take out necessary items in a timely manner. To automate them, the structure and control become very complicated, and the device is expensive. Become.

Also, press the outer circumference of the standing take-up roll to slide the movable support plate, temporarily support the take-up roll with the movable support plate, and pull out the movable support plate when all the necessary take-up rolls are ready. Therefore, regardless of the smoothness of the top surface of the pallet, for example, even a pallet with an uneven top surface, the winding roll can be transferred smoothly and accurately, and transferred to the movable support plate. Since a large force is not applied to the take-up roll when it is placed, the damage and deformation can be prevented.Also, with a pair of regulators,When the movable support plate is removed from the take-up roll receiving position, the take-up roll is constrained so as not to be displaced in the pallet width direction, so that the stacking pattern of the take-up roll on the pallet can be prevented from being broken.
[0050]
Furthermore, even if it is a winding roll with a small outer diameter and a wide width | variety, the fall can be prevented by pressing the standing upper end surface of the winding roll with a pressing member. For this reason, the speed of the transport vehicle can be increased so that it can move to the target position in a short time, and the take-up roll can be reliably transferred onto the movable support plate.
[0051]
Claim 2Winding ofAccording to the vertical take-up palletizer, the take-up rolls can be stacked vertically on the pallet while being sorted. In addition, lead time can be shortened and the full automation of the equipment becomes easier than before, and it is necessary to install a sorter with automatic roll storage and take-out functions, or an automatic warehouse, which is complicated and expensive in structure and control. Disappear.Also, a rail provided along the front edge of the movable support plate at the support positionSince the transport vehicle is guided in a certain direction and only the travel distance needs to be controlled, the transport vehicle can be easily controlled, and the transport vehicle can be brought to the target position in a short time.
[0052]
Claim 3According to the vertical stacking palletizer, the pallet can be loaded and unloaded by the crossing conveyor and the infection conveyor so as not to obstruct the movement of the transport vehicle. It is possible to fully automate the loading and unloading of pallets to and from the position.
[0053]
Claim 4In the vertical take-up palletizer, when the movable support plate is removed from the take-up roll receiving position, the take-up roll is restrained so that it does not shift in the pallet width direction. It can be prevented from collapsing.
[0054]
Claim 5According to the vertical stacking palletizer, when the movable body is in the retreat limit, the base of the movable body and the arm of the intermediate movable base are overlapped, and the movable body moves relative to its own intermediate movable base. Since the take-up roll can be pushed out by the distance plus the moving distance of the intermediate movable platform relative to the transport vehicle, the installation space of the transport vehicle can be saved.
