The present invention relates to a packaging bag sealing device that can be automatically sealed.

(Problems to be solved by the invention) Conventionally, when packaging objects using a bag,
For example, a packaging means such as that described in Japanese Utility Model Publication No. 16752/1983 is used. That is, this conventional means:
As shown in FIG. 5, after the object to be packaged 4 is housed in a bag 35 having an opening 31, the bag 35 is sealed and fused to seal and close the opening 31.

However, in the conventional method, after the article 4 to be packaged is housed in the bag body 35, the bag body 35 is sealed with a sealer 40.
No mechanical device has been developed that can fully automatically perform a series of sealing and fusing operations, and the bag body 3 containing the object to be packaged 4
5 by hand to position the sealer 40, and then manually move the sealer 4 to the position where the sealer 40 is placed.
The seal fusing operation for the cough bag body 35 was performed under zero operation control.

Therefore, in the past, the sealing work of the bag was very complicated and the workability was poor, and there were also problems such as increased labor costs and extremely high product costs. There was a strong demand within this industry for this to be improved.

The present invention was invented in view of the above-mentioned problems.
The purpose is to use a mechanical device to automate a series of sealing operations of the cough bag after the object to be packaged is placed inside the bag.

(Means for Solving the Problems) The present invention provides transport, positioning, and detection of a bag when sealing is cut on a bag containing an object to be packaged, control of the operation of a siniller,
The present invention was designed to solve the problems of the prior art by developing an apparatus that can continuously perform a series of process operations such as post-processing after melting and cutting the bag seal.

That is, the gist of the configuration of the present invention is that the transfer table 11 is provided in a downwardly inclined manner so as to be able to slide and transfer the bag body 35 containing the object 4 to be packaged by its own weight, and the transfer table 1
a positioning stop member 13 that is provided on the top surface of the bag body 13 so as to be freely protrusive and retractable and that can lock and stop the transferred bag body 35 when the bag body 35 is projected onto the top surface; and a bag that is positioned and stopped by the positioning stop member 13. a detection means for detecting the presence of the body 35; and a bag 35 positioned by the positioning stop member 13 by the detection of the presence of the bag 35 by the detection means.

(Function) Therefore, in the sealing device characterized by the above configuration, when the bag body 35 containing the object to be packaged 4 is fed to the transfer table 11, the bag body 35 is first fed along the inclined surface of the transfer table 11. The bag body 35 that is slid forward can be brought into contact with and locked by the positioning stop member 13 to be positioned and stopped at a predetermined position, and the detection means detects the presence of the nuclear bag body 35 and After the body 35 is positioned and stopped, the sealer 18 starts operating and performs a seal fusing operation on the bag body 35, thereby automatically sealing the bag body 35. After the sealer 18 performs the seal fusing operation for a predetermined period of time, compressed air is blown from a separately provided air nozzle 27 to remove the film residue 37 of the bag body 35 generated during the seal fusing operation to the transfer table 11. This allows the remaining pieces 37 to be removed from the outside of the bag body 35, and it is possible to avoid the situation where the remaining pieces 37 become a hindrance to the next sealing operation of the bag body 35. Furthermore, after the sealing work is completed, the bag body 3 is

Reference numeral 27 indicates an air nozzle installed at a lateral position slightly above the table 25, and the air nozzle 27 blows compressed air in a lateral direction perpendicular to the transfer table 11 at approximately the same time as the limit switch 26 is turned on. It is set to automatically stop blowing air after a certain period of time. Further, a cylinder 14 for operating the positioning rod 13 is also provided to operate in conjunction with the limit switch 26, and at the same time as the limit switch 26 is turned on, the positioning rod 13 is once lowered from the surface of the transfer table 11. After that, it is set to be raised again above the transfer table 1.

The present embodiment has the above configuration, and its usage and operation will be explained next.

That is, in this embodiment, for example, as shown in FIG.
A notch 32.32 is formed on the edge of the film 30 on the one end side where 1 is formed, and a hole 33.33 is bored at a position near the inside of the notch 32.32. A bag body 3 formed with a header 34 with an advertisement etc. on the side
5 is used as an example. First, a large number of the bags 35 are polymerized and the bag body setting table 8 of the filling device 1 is used.
At that time, the hole 33 of the bag 35 is
．． 33 through which both ends of the U-shaped shaft 36 are inserted, the bag body 35 can be properly positioned and fixed, and then compressed air is blown into the bag body 35 from the air nozzle 9 to widen the opening 31. By pushing the packaged article 4 with the pushing body 5, the packaged article 4 is pushed into the bag body 35.
It is filled with. Further, even after the object 4 is filled, if the pushing body 5 is moved forward to push the object 4, the film 30 of the bag 35 will be moved to the position of the hole 33.33 and the notch 32.32. The bag 35 is broken in the middle and the attachment by the shaft 36 is released, and as a result, the bag 35 is transferred to the shooter 10 while still containing the article 4 to be packaged.

Next, the bag body 35 transferred to the shooter 10 falls along the slope of the shooter 10 and is supplied to the sealing device 2 according to this embodiment. slides down the surface of the inclined transfer table 11 and comes into contact with the positioning rod 13, thereby being locked and positioned. In addition, the cough bag body 35 is connected to the limit switch 1.
Since the limit switch 17 is turned on by passing over the contact piece 16 of No. 7, the sealer main body 22 approaches the receiver 25 as shown in FIG. 3, and the sealer 18 starts the sealing operation. It is. Therefore, as shown in the figure, the bag body 35 which is sandwiched between the sealer body 22 and the receiver of the sealer 18 by the stand 25 is sealed so that the opening 31 is closed by the heating plate 23, and the bag body 35 is sealed by the heating plate 23. One end of the seal is melted by the heating wire 24, and the seal melt-cutting operation is completed after a predetermined time period preset by a timer attached to the sealer 18 has elapsed. However, after the sealing operation is completed, the limit switch 26, which was in contact with the arm 21 during the sealing operation of the sealer 18, is turned on as the arm 21 rises and leaves. At the same time as or immediately after the end, the air nozzle 27 starts blowing compressed air, and as a result, the film residue 37 of the fuse-cut bag 35 is blown away to the side of the device 2, and the film residue 37 is discarded. This is done in a suitable manner. Therefore,
The film remains on the stand 2 even during the next sealing operation.
It is possible to prevent the seal from remaining on the surface of the sealing material 5 and hindering the sealing operation, thereby ensuring proper sealing operation at all times.

In addition, since the positioning rod 13 descends and temporarily enters the notch groove 12 of the transfer table 11 at the same time as air is blown from the air nozzle 27 after the sealing operation is completed, the sealed bag body 35 is placed on the transfer table. 11 and is automatically supplied to the next different work process position.

In the above embodiment, the transfer table 11 has a cutout groove 12.
A plurality of bottle-shaped positioning rods 1 are carved in the notched groove 12.
3 is inserted through the positioning stop member 13 so as to be vertically movable, but the specific shape, number, and transfer table 11 of the positioning stop member 13 according to the present invention are
The manner in which it is mounted is not limited to this, but the point is that it can be moved freely onto and retracted from the transfer table 11, and when it is projected, it can lock the bag body 35 and position and stop the bag body 35. It is sufficient if it is provided. However, the positioning stop member 13
It is preferable that the sealing member is provided so as to be adjustable in position along the transport direction of the bag body 35 as in the above embodiment, so that the seal fusing position of the bag body 35 can be changed and adjusted as appropriate.

Further, in the above embodiment, both the heating plate 23 and the heating wire 24 are provided in the sealer main body 22 of the sealer 18, and the welding and sealing of the film of the bag body 35 and the fusing and cutting are performed at different positions. This has the advantage that the strength of the welded seal can be increased; however, the present invention is by no means limited to this; for example, the seal of the film of the bag body 35 may be fused and cut at the same location.

Furthermore, the overall structure of the sealer 18 according to the present invention is not limited to the above embodiment, and the point is that a separately provided detection means is used to detect the state in which the bag body 35 is positioned by the positioning stop member 13. It is sufficient that the seal fusing operation is started upon detection, and the seal fusing operation is completed after a predetermined period of time has elapsed, so that the seal fusing operation is movably provided above or on the top surface of the transfer table 11. If the time required to melt the seal of the bag body 35 is extremely short, a timer or the like is not necessary.

Further, in the present invention, the specific configuration of the detection means for detecting the state in which the bag body 35 is positioned by the positioning stop member 13 may be such that the contact piece 16 is protruded above the transfer table 11 as described above, or the contact piece 16 is The design is not limited to the switch 17, and the specific shape and mounting position of the air nozzle 27 for blowing away the film residue 37 after the seal fusing operation is completed can be changed.

In addition, in the above-mentioned embodiments, an example is given in which the packaging material filling device 1 is installed in front of the sealing device according to the present invention. The present invention is intended for the sealing operation after filling and housing the objects 4, and does not question the configuration of the filling device 1, etc., and does not question the presence or absence of the filling device itself. Incidentally, the filling device 1 is used for packing objects 4 as in the embodiment described above.
In addition to stroking by pushing the object 4 with a pushing body 5 to mechanize the entire filling operation of the object 4 to be packaged, the object 4 to be packaged is manually placed into the bag 35 set on the bag setting table s. It is possible to configure the container to be filled sequentially.

(Effects of the Invention) As described above, the present invention provides a retractable positioning member on a transfer table for transferring a bag containing an object to be packaged, and locks the bag to the member. The cough bag body is positioned by the bag body, and after the detecting means detects the presence of the positioned bag body, the sealer is activated to perform a seal fusing operation on the bag body for a predetermined time. , it has become possible to mechanize and automate the entire series of operations related to sealing and sealing of bags containing objects to be packaged, and the work efficiency has been improved compared to the conventional means of performing a series of sealing operations manually. In addition to being able to significantly improve the number of workers, we have achieved the extraordinary effect of significantly reducing the number of workers and the cost of packaging using bags.

Moreover, since the present invention is provided with a separate air nozzle for removing film debris generated when the seal is cut after the seal is melted and cut on the bag body, it is not necessary to repeat the sealing operation of a plurality of bags. When carrying out the sealing operation, it is possible to suitably eliminate the problem that the film residue becomes a hindrance to the operation, and to maintain the series of sealing operations in a comfortable condition at all times. Since it is constructed so that it can be slid along the platform by its own weight, there is no need to use any special equipment for the transport means of the cough bag, and the cost of the device is extremely low. After the sealing operation is completed, the bag can be automatically transferred to the next work process position by an extremely simple means of retracting the positioning member that positions the bag. It also has the practical benefit of allowing very smooth transfer and discharge operations.
