Abstract

PURPOSE:To permit a dropping object to be released and to drop by using a stopper pin in contact with a fitting metal, provided in the face of the upper part of the pivotally turnable fitting metal hanging and lifting the dropping object. CONSTITUTION:Under the condition that a dropper 10 is hung down by a lever 1, when the lever 1 is moved upwards through an air cylinder 6, the cam slope face 12 of the lever 1 comes into contact with a stopper pin 3, the lever 1 is turned counterclockwise, a hanging pin 2 is removed from a coupled portion 11, and the dropper 10 drops to give an impaction to a substance to be impacted. When coupled portion 11 is lifted up and the pin 2 is coupled, the lever 1 is brought down through an air cylinder 6, whereupon the slope face 13 of the lever 1 comes into contact with the hanging pin 2. When the lever 1 is further brought down, the lever 1 is turned against the tension of a spring 4 and the hooked portion 11 is inserted under the hanging pin 2. The position of the stopper pin 3 is designed to be freely and vertically adjusted. Thus, the impaction force can be freely adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drop impact device that uses gravity to drop an object and apply impact.

In general, devices that apply impact to an object include those that use the counterforce of a spring and those that use gravity, both of which use the inertia that occurs when a sudden stop (collision) or a sudden change in the direction of the force occurs. It utilizes the power of

When applying impact in the vertical direction, the force (potential energy) caused by falling can be used, but conventionally, a cam like a shear (cutting machine) is used, or a machine that pulls up to a certain height like a pile driver is used. I was trying to make it fall at this position. However, when a cam is used, it is difficult to change the falling stroke, and there is a risk of wear due to the gravity of the falling object being applied to the tip of the cam at the switching point between rising and falling. However, in order to drop it at a certain height, a disconnection device from the lifting drive unit is required, which is complicated and expensive.

The present invention was made in view of the above situation, and an object of the present invention is to provide a drop impact device that has a simple structure and can freely adjust the impact force.

The falling impact device of the present invention is formed to apply impact by dropping an object using gravity, and includes a lever mounting bracket, a means for moving the falling object upward via the lever, and a rotating mechanism for the lever mounting bracket. It can be attached freely and has a locking part with a rotatably formed contact part at the bottom to which the lifting pin of the falling object is locked, and as the cam slope comes into contact with the stopper bin as it rises, it is rotatably driven. The lever includes the lever formed so that the lifting pin can be removed when the lifting pin is removed, and the stopper pin whose contact portion is rotatably formed so as to be in contact with the cam slope.

An embodiment of the drop impact device of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a front view, and FIG. 2 is an explanatory diagram of each position when the lever in FIG. 1 is operated. In FIG. 1, reference numeral 1 denotes a lever. As shown in FIG.
1, has a cam slope 12 on the upper end surface, and has a cam slope 12 on the lower end surface.
It has 3. Reference numeral 6 denotes a stopper bin, which has a rotatable contact portion through a ball bearing, and is configured to contact the cam slope 12 and rotate the lever 1, which is displaced upward, in a counterclockwise direction. 4 is a spring, and 5 is a pin, which together control the posture of the lever 1 when the lifting pin 2 of the falling object 10 is locked by the locking part 11 as shown in FIGS. 1 and 2 (A). shaped to hold. Reference numeral 6 forms a means for lifting the lever mounting bracket 7 upwardly by an air cylinder. 8 is fixed to the falling object 10 with a slide base, and is attached via rollers 15 to the inside of the frame 9 so as to be able to rise and fall.

In the above structure, when the falling object 10 is suspended in the posture of the lever 1 shown in FIG. 1 and FIG. 3, the lever 1 is rotated in the counterclockwise direction as shown in FIG. .

Also, when locking the lifting pin 2 to the locking part 11 again, at this point the lever mounting bracket 7 is at the upper position and the slide pace 8 is at the lower end, so the mounting bracket 7 is lowered via the air cylinder 6. When the lever 1 is lowered, the slope 13 of the lever 1 comes into contact with the lifting pin 2 as shown in FIG.
The locking part 11 is now located at the lower part of the lifting pin 2.

At this point, when the lever mounting bracket 7 is lifted up through the cylinder 6 and moved further upward, the lever 1 comes into contact with the stopper bin 3 again, the lifting pin 2 is removed, and it falls freely. Since the stopper bin 3 is formed so that its mounting position in the vertical direction can be adjusted, the fall distance H can be adjusted and the impact force can be adjusted.

Further, like the stopper bin 3, the lifting pin 2 also has a contact portion rotatably formed via a pole bearing.

As described above, the drop impact device of this embodiment has a simple structure consisting of only a means for lifting a falling object, a stopper bin, a leno<- and a lifting pin, and the sliding part is also formed to be rotatable, so that it does not wear out. There are no parts, and you can adjust the fall distance to apply impact.

In addition, although the above embodiments have been described with reference to the case where an air cylinder is used to displace a falling object upward, the effect is the same even if the falling object is displaced by other means.

As described above, the drop impact device of the present invention has a simple structure and the effect that the impact force can be freely adjusted.
