Abstract

The present disclosure provides a continuous launcher including a pressing tube having a first hollow portion therein, a launch unit having a second hollow portion therein, disposed at a front side of the pressing tube in a spaced manner, and launching a launch object using air compression force, a piston supply unit provided at a rear side surface of the pressing tube, including a plurality of pistons therein, and supplying the pistons one by one, a piston loading unit connected to a rear end of the pressing tube, and moving the piston to a load position, and an operating fluid supply unit supplying an operating fluid to press forward the piston, wherein the launch unit includes a launch tube having a launch hollow portion with the launch object therein, and a diaphragm.

First claim

The invention claimed is:

1. A continuous launcher comprising:
a pressing tube having therein a first hollow portion in which a piston is movable;
a launch unit disposed at a front side of the pressing tube in a spaced manner based on a launching direction, for launching a launch object using compression force, the compression force being generated by the piston moved forward along the first hollow portion;
a piston supply unit provided at a rear side surface of the pressing tube and including therein a plurality of pistons, wherein the piston supply unit supplies the pistons one by one to a rear end of the first hollow portion;
a piston loading unit provided at a rear end of the pressing tube, and allowing the piston to be moved from a supply position of the piston supplied into the first hollow portion to a load position within the first hollow portion, at which the piston is loaded; and
an operating fluid supply unit supplying an operating fluid between the supply position and the load position of the piston, to press forward the piston from the load position,
wherein the launch unit comprises:
a high-pressure connector having therein a second hollow portion, in which the piston is movable; a launch tube having a solid launch object therein, provided with a launch hollow portion serving as a path for launching the solid launch object, the launch tube being connected to a front end of the high-pressure connector to communicate the launch hollow portion and the second hollow portion with each other; and a diaphragm disposed to block between the second hollow portion and the launch hollow portion to generate air compression force within the second hollow portion, and which is exploded to launch the launch object when the air compression force reaches a preset pressure,
wherein the launch hollow portion has a cross section smaller than that of the second hollow portion, wherein the launch unit and the pressing tube are spaced apart from each other, and wherein a front end of the first hollow portion and a rear end of the second hollow portion are disposed to face each other.

2. The continuous launcher of claim 1 , wherein the piston loading unit comprises:
an outer cylinder fixed to the rear end of the pressing tube;
an inner cylinder configured to be movable back and forth within the outer cylinder; and
a load piston movable back and forth within the inner cylinder, and allowing a new piston to be placed at a supply position when being moved backward, and the piston to be placed at a load position more forward than the supply position when being moved forward,
wherein the load piston comprises a load bar inserted into the first hollow portion through the inner cylinder and the outer cylinder, and wherein the load bar is formed in a shape of a bar extending into a shape having the same cross section as that of the first hollow portion.
