Work table installed on a bucket conveyor, suitable for manual insertion of one or more items by the operator. The operator places the item into the tray, which contains all the items that will be inserted into the finished bag. The operator can easily access the tray through a slot in the table. The tray passes by, stopping for a preset time in front of the operator, before being filled and moving on to the packaging machine. The tray will then ascend via a conveyor belt to the entrance of the packaging machine, which will receive the items in the tray and form the bag.
