DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device that forms an open elongated bag for accommodating a wet umbrella, and allows a user to easily place the bag over the umbrella. .

Prior Art In places where users bring in umbrellas, such as stores that sell products that would be a problem if they get wet, theaters, movie theaters, cafeterias, etc., a plastic bag is provided at the entrance to allow users to store their wet umbrellas. was traditionally done.

In this case, the plastic bag is folded flat and the plastic bags are in close contact with each other, and the user receives the bag, opens the entrance and inserts the umbrella, but the user has to peel off the plastic bags that are stuck together while holding the umbrella. is surprisingly difficult.

Therefore, a device that automatically forms an umbrella bag has been proposed, but the conventional example (Japanese Patent Publication No. 55-43965) has a cylindrical body into which an umbrella is inserted, and the user inserts the umbrella into the cylindrical body. After pulling out the umbrella along with the cylindrical plastic film that covered the cylinder, a switch is turned on manually or automatically to drive the cylinder drive mechanism to move the cylinder backward, and a device is installed that crimps and cuts the film. The device was driven to press and cut the rear end of the film that was pulled out together with the umbrella.

Problems to be Solved by the Invention In other words, the user must insert the umbrella into the barrel and pull out the film together with the umbrella, and even if the switch is automatically turned on, the barrel will move back and the film will not be removed. It is difficult to use the device in a short time and simply because it requires a lot of work and a long waiting time.

In addition, since this device does not have a means to support the end of the film, the film is always pulled out in a horizontal direction, and the cylinder is supported in a horizontal position, allowing the insertion of an umbrella,
Since it is necessary to draw out the umbrella horizontally, it is inconvenient that it is difficult to support the umbrella in a horizontal position after the umbrella is pulled out horizontally together with the plastic film until it is crimped and cut.

This can be a very troublesome task, especially when you have baggage.

The present invention was made in view of the above, and its purpose is to support an umbrella bag in an open state facing upward, to facilitate insertion of the umbrella, and to allow the umbrella bag to remain in the state in which it is covered. The object of the present invention is to provide an extremely convenient umbrella bag forming device that can be taken out.

Means and Effects for Solving Problems The present invention provides a winding means for winding and storing a belt-like cylinder made of a thin resin, a delivery means for sending the belt-like cylinder upward from the winding means, and a delivery means for feeding the belt-like cylinder upward from the winding means. an opening means for opening the upper end of the belt-like cylinder that has been sent out; a pulling means for supporting the upper end of the belt-like cylinder opened by the opening means and lifting it upward in the open state; Umbrella support means that narrows the lower end of the belt-shaped cylinder and supports the umbrella by receiving contact with the stones of the umbrella; Welding means that welds the belt-shaped cylinder in the width direction at a lower position of the umbrella support means; and Welding means a cutting means for cutting directly below the welded portion; an umbrella insertion detection means for detecting the load on the umbrella support means; This is an umbrella bag forming device equipped with an opening means for opening the umbrella bag.

The belt-shaped cylinder wound around the cylinder winding means is sent upward by the sending means, opened by the opening means, and pulled up by the pulling means in an open state while supporting the upper end of the belt-shaped cylinder, so that the umbrella can be opened. To facilitate insertion, the umbrella support means is narrowed at the bottom, the lower position is welded by the welding means, and the part directly below it is cut by the cutting means, so that the umbrella is in a state where it waits for the umbrella to be inserted. The umbrella insertion detection means is activated, and the upper end of the belt-shaped cylinder is opened, allowing the umbrella to be taken out together with the bag.
