Abstract

PROBLEM TO BE SOLVED: To provide an apparatus for filling an object to be packaged into a bag with a high density. SOLUTION: In order to put an object to be packaged into a bag while adjusting the directional property of the object, this bagging machine is designed to move the bag suspended by a clamp along an endless track together with the clamp and house the object in the bag in the moving course. In this machine, when an impact blow is given to a hammering core 13 with a rotary cam 18, a channel-shaped member 10 slidably supported by a sleeve 17 with the aid of a guide member 14 is vibrated in a lateral direction to shake the bag 26 suspended by the clamp 25. An object to be packaged such as, for example, flaked dried-bonito in the bag is settled flat by the lateral shaking of the bag and can be packaged in reduced bulk. Two balance springs 20, 21 for keeping the neutrality of the channel-shaped member 10 give an aftereffect to the vibration of the channel-shaped member 10 even after the rotation of the cam 18 is stopped, and adjust the uniform directional property of the object.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for densely filling an object to be packed into a bag.

[0002]

2. Description of the Related Art As shown in FIG. 4, a bag 3 having a seat plate 2 mounted thereon is vibrated up and down 4 integrally with the crank by the rotation of the crank 1 as shown in FIG. Due to the application of inertia due to vibration, the packaged object 5 in the bag 3
An apparatus for automatically lowering the height of a bag toward the bottom of a bag is disclosed.

[0003]

The inertial force of an object is proportional to the weight of the object. For example, when the object to be packaged is shaved and the weight is light, such as bonito or feathers, the inertia force is equal to nothing. Conversely, there is a problem that these objects swell with air and increase in bulk. That said, push rod 6 from above
When the object 5 is forcibly pressed, there is a disadvantage that the object is crushed or broken.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a bag, which has been hooked down by a clamp, is moved along an endless track integrally with the clamp in order to sink the packaged object into the bag while adjusting the direction. And a bag stuffing machine for accommodating an article to be packaged in the bag being moved, wherein the groove-shaped member is formed so that two opposing walls of the groove-shaped member are located on both sides of the bag. While the member is installed in the middle of the endless track, a guide member extending laterally from the groove-shaped member is slidably supported on the machine base, and the groove is swingable in both wall directions. A striking means for applying a striking force to the shaped member for a certain period of time is provided.

[0005]

When the striking means exerts a force on the groove member for a certain period of time, the groove member vibrates in the direction of both walls due to the sliding of the guide member, and the bag moves down the endless track by being clamped by the clamp. The roll is rolled, and at the same time, the lateral vibration is applied to the packaged items inside. Thin paper-like objects such as shaved bonito have a flattened directionality due to such rolling, and the swelling phenomenon due to the conventional pitching is eliminated, so that the bulk is reduced.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A tapping bar 13 is horizontally projected from a channel-shaped member 10 provided with two facing walls 11 and 12, and a guide member 14 fixed parallel to below the tapping bar is fixed to a machine base 15 by a bracket. A hitting means formed by a rotating cam 18 is provided opposite to the end of the tapping core 13 so as to be slidably supported by a sleeve 17 of 16.

Further, between the member 19 hanging from the end of the guide member 14 and the machine base 15, two balancing coil springs 20 and 21 are provided to attract each other. Since the attraction of the two coil springs causes a tendency to hold the channel member 10 at the neutral position, the rotary cam 18 relatively moves the tapping center 13 against the retraction force of the coil springs 20 and 21. At short intervals,
The channel member 10 vibrates in the lateral direction due to the sliding of the guide member 14. Therefore, when the bag 26 suspended by the clamp 25 enters the channel member 10, the bag is hit by the walls 11 and 12 on both sides. In this case, since the reciprocating beating is performed on the bag, the number is doubled as compared with a device for hitting the bag from below.

FIG. 3 shows the vibration width A and the vibration pitch B of the groove-shaped member. In FIG. 1, after the rotation of the rotary cam 18 is stopped, the groove-shaped member is balanced by the two coil springs 20 and 21. In FIG. 10, as shown in FIG. 3, the width A and pitch B of the vibration gradually attenuate while leaving a lingering sound. Due to the attenuation of the vibration, the packaged item in the bag is settled down in a proper direction, and the settling is more effective and desirable than stopping the vibration suddenly.

FIG. 2 shows another embodiment of the hitting means, in which a pump 31 and a fluid cylinder 32 are connected via a 4-port, 3-position electromagnetic directional valve 30, and the directional valve 30 is connected between both side positions. To switch the piston rod 33
Reciprocates as indicated by an arrow 44. Therefore, the piston rod 33 is changed to the rotary cam 18 of FIG.
The connection to 3 enables the groove-shaped member 10 to vibrate.
In the neutral position of the directional valve 30, the piston rod 33 is free.

In the apparatus shown in FIG. 4, every time the length of the bag 3 hung by the clamp 7 changes, it is necessary to adjust the entire vibrating means up and down in accordance with the bag. A considerable gap C can be formed between the bag and the bottom of the channel-shaped member, so that no adjustment is necessary even if the length of the bag becomes so large.
