Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can lid packaging apparatus in which a plurality of can lids are stacked and packed in a bag to form a can lid package that can be shipped. [0002] Hitherto, it has been known that a predetermined number of can lids are stacked in a column shape and shipped as a can lid package packed in a bag. [0003] In a can lid package, a stacked can lid group is stored in a bag, a bag opening of the can lid package in a state in which the can lid group is stored is closed, and then the longitudinal direction is set to be horizontal to a predetermined length. Each bundle is bundled, and large quantities can be shipped and transported at one time.
These steps are sequentially performed by a can lid packaging device including a bagging device, a folding device, and a stacking device. To elaborate,
The bagging device is configured to divide a predetermined number of can lids that are continuously and horizontally supplied in a stacked state into can lid groups to form a group of can lids, and on the other hand, to form a paper lid that is supplied in a state of being folded into a flat state. The bag mouth of the bag is opened and supported horizontally to face the can lid group. Next, the can lid group is pushed toward the bag mouth of the bag and inserted into the bag. Thereafter, the bag is dispensed in an upright state with the bottom of the bag facing downward. The folding device is provided on the downstream side of the bagging device, supports the can lid package transferred and thrown from the bagging device in an upright state, folds the bag mouth of the bag and closes it, and then raises the can lid package. Pay out in the state. The stacking device is provided on the downstream side of the folding device, and stacks the closed can lid packages in a plurality of rows and a plurality of stages. A transfer device for transferring the can lid package is provided between the bagging device and the folding device, and between the folding device and the stacking device. A transfer device provided between the bagging device and the folding device transfers the can lid package discharged from the bagging device in an upright state to the folding device in a vertically upright state. A transfer device provided between the folding device and the stacking device transfers the can lid package discharged from the folding device to the stacking device in a state where the package is horizontal in the longitudinal direction. However, since the can lid package discharged from the folding device is in the upright state, it is necessary to convert the can lid package from the upright state to the horizontal state in order to transfer it to the stacking device. For this reason, for example, at the payout position of the folding device, a device is provided that horizontally folds the standing can lid package continuously with the payout of the folding device, and the can lid package that is in the horizontal state at the payout position of the folding device is provided. Is provided to a device corresponding to the input portion of the stacking device, and further,
A plurality of devices are required between the folding device and the stacking device, such as providing a device for transferring the can lid package transferred by the transfer device to the charging section of the stacking device. In addition, when the can lid package is in the horizontal state at the dispensing position of the folding device, the other closed can lid package that is subsequently closed cannot be dispensed, which hinders the efficiency of the closing operation by the folding device. There are inconveniences. Further, when the can lid package is folded down horizontally, the can lid package in the horizontal state is prevented from interfering with the folding device and other can lid packages subsequently discharged from the folding device. It is necessary to keep the work position for folding the lid package horizontally away from the folding device by at least the length of the can lid package. As a result, the scale of the can lid packaging apparatus becomes large, and there is a disadvantage that a large installation space is required. Further, conventionally, the folding device has been performing a closing operation by a so-called medicine folding method of folding the bag opening of the bag so as to be rolled up and maintaining a closed state, but in order to increase the working speed, in recent folding devices, A method of applying a hot-melt adhesive or the like to a bag opening and folding the bag to maintain a closed state is adopted. In this way, even when the closing operation of the can lid package by the folding device is accelerated, the can lid can be converted from the upright state to the horizontal state through a plurality of devices as described above. The transfer distance of the lid package to the stacking device is increased, and not only the scale of the entire device is increased, but also the transfer speed to the stacking device is, for example, every time a can lid package in which 250 can lids are packaged. There is an inconvenience that the speed of the closing operation is meaningless because it is relatively slow at about 3.5 parts. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned disadvantages, and an object of the present invention is to provide a can lid packaging apparatus which can be made compact and which can improve the efficiency of can lid packaging. Aim. [0007] In order to achieve the above object, the present invention is to insert and store a predetermined number of stacked can lids in a column shape into a flat folded bag from the bag mouth. A bagging device for forming a can lid package, a folding device provided downstream of the bagging device, for conveying the can lid package in an upright state, and for folding the bag lid to close the bag opening, and a downstream of the folding device. And a stacking device for stacking a plurality of can lid packages in a horizontal state, the stacking device being provided with a plurality of can lid packages in a horizontal state. In, provided so that the input portion of the stacking device is located above the payout portion of the folding device, the bagging device, the folding device and the stacking device are disposed in a substantially U-shape in plan view,
