Description

[Detailed description of the invention] (Field of industrial application) The invention relates to a diaphragm device for hitting the bottom of packaging bags.
The height of the diaphragm can be adjusted freely even when the automatic packaging machine is in operation.

(Prior Art) In an automatic packaging device, a device fills a packaging bag which is suspended by supporting arms at both vertical edges and then taps the bottom of the bag with a vibrating plate.
This is disclosed in Japanese Utility Model Publication No. 57-60961 and is publicly known, but the height of the diaphragm needs to be adjusted depending on the size of the packaging bag, the bulk of the item to be packaged, etc.

Conventionally, while the packaging machine was running, the state of contact between the diaphragm and the bag was visually checked, and if it was necessary to make adjustments, the packaging machine was stopped and the bolts were loosened using a tool such as a wrench to adjust the vertical movement of the support rod. The height of the diaphragm is adjusted and fixed again with nuts, and if readjustment is deemed necessary, the above adjustment operation is repeated, so the operation of the packaging machine must be stopped each time adjustment is made. However, this method requires wasted time and has the disadvantage of impairing packaging workability.

(Problems to be solved by the present invention) In view of the above, the present invention makes it possible to freely adjust the height of the diaphragm even during operation, without stopping the packaging machine and impairing workability. This is the goal of solving problems.

(Means for solving the problem) The present invention is aimed at realizing the goal stated in the previous section, and a threaded portion 6 is provided on the support rod 5 connected to the bottom-beating diaphragm 3. 2nd part on the threaded part
A nut body 9 having a pulley 10 is screwed together, a vibration lever 23 is connected to the nut body, and a first pulley 16 rotated by a handle is provided, and an elastic belt is attached to the first pulley 16 and the second pulley 10. 1
8, the nut body 9 is rotated via the belt 16, and the support rod 5 is moved up and down to adjust the height of the diaphragm 3. Even when the automatic packaging machine is operating, the height of the diaphragm can be freely adjusted by simply rotating the first pulley using the handle without stopping the operation.

A preferred embodiment of the invention is described in the following section.

(Example) In the figure, 1 is a table of an automatic packaging machine, and a is a packaging bag that is hung by gripping the vertical edges on both sides by one pair of support arms among a plurality of pairs protruding from the rotary plate of the packaging machine. Then, the article to be packaged b is filled at the filling station.

The diaphragm 3 of the present invention is 1 following the filling station.
The diaphragm 3 is mounted on a support rod 5 which extends through the center of a ball bearing 4 mounted on the table 1 and extends to the lower surface of the table 2. The support rod 5 is provided with a threaded portion 6 on the lower surface than the table 1, and one or several rotation stop plates 7 are horizontally protruded from the lower end and fixed.
A pair of sliding guide plates 8 provided on the machine base 2 of the table 1
It is fitted into the rotation stopper plate 7 so that it can freely slide up and down.

A second pulley 10 is provided on the threaded portion 6,
A nut body 9 with a ring plate 11 provided on its lower surface is screwed together.

Reference numeral 12 denotes a shaft supporting cylinder which is passed vertically from the upper surface of the table 1 and fixed to the table 1. A bracket arm 13 is attached to the lower end, and a handle 1 is mounted inside.
A rotary shaft 14 provided with a rotary shaft 14 is passed freely through the rotary shaft 14, a boss of a first pulley 16 is fixed to the lower end thereof, and a set screw 17 for stopping the rotation of the rotary shaft 14 is screwed to the upper part of the table 1.

A round belt 18 made of elastic silicone rubber or the like is hung between the first pulley 16 and the second pulley 10, and is attached to the grooved support roller 20 provided on the hanging piece 19 of the bracket arm 13 and the protruding arm 21 of the nut body 9. The provided grooved presser roller 22 contacts the round belt 18 from below and above to produce a guiding action.

Reference numeral 23 denotes a vibration lever supported by a shaft 24 for reversible rotation, and as shown in FIG. 2
6 and 26 are passed horizontally through the bifurcated portion 25 to connect them. Further, in the vibration lever 23, a roller 28 at the tip of a protruding arm 27 protruding from the shaft 24 is brought into contact with the circumferential surface of a vibrating cam 29 having several protrusions. The vibration cam 29 is fixed to the rotating shaft 30.

(Function) The present invention uses the vibrating plate 3 to visually check the degree of beating of the packaging bag a, and if there is too much or too little, rotate the handle 15 in either direction, and run the belt 18 using the first pulley 16. 2 pulley 10 rotates relatively upward or downward on the threaded portion 6, and thereby the support rod 5 moves upward or downward to move the diaphragm 3 up and down, thereby vibrating the bottom of the packaging bag a. Adjust the degree of hitting using the lever 23.

(Effect) Although the present invention does not change the amount of vibration caused by the vibration lever 23 of the diaphragm 3, the handle 15 rotates the first pulley 16, and the round belt 18 rotates the nut body 9 provided with the second pulley 10. As a result, the height of the diaphragm 3 above the table 1 can be changed by moving the support rod 5 up and down, and the degree of hitting the bottom of the packaging bag a can be freely adjusted. Unlike conventional methods, the automatic packaging machine does not have to be stopped, and the adjustment can be made without stopping to directly check the degree of beating of the packaging bag.Therefore, there is no wasted adjustment time, and there is no need to reduce packaging efficiency. It has no effect.
