BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag removing device for removing a deposit attached to a bag opening before sealing in which a filler is stored.

[0002]

2. Description of the Related Art As shown in FIG. 3, a basic packaging system of an automatic packaging machine for foods or the like absorbs and lifts a bag 1 in a bag storage device by a suction cup 11 of a bag supply device A, and grasps a table T side. Device B
Bag feeding process I, which is delivered to the bag gripping claws 2a, 2b, a stamping process II for stamping the production date of the food on the surface of the bag 1 held by the stamping device C, and a mouth of the bag 1 with the bag opening device D A bag opening step III, which is opened by the suction cup 12, a filling step IV, V, in which the filling material and the filling liquid are filled in the bag 1 by the filling device E, a first sealing step VI, a second step, in which the bag mouth is sealed by the sealing device F It comprises a sealing step VII, a discharging step VIII for discharging the packaged bag 1 to the next step, and the like.

In the above-mentioned packaging system, a filling process IV,
The bag 1 containing the filling material and the filling liquid in the sealing process V
Although the bag mouth is sealed with I and VII, when filling the bag 1 with the filling in the filling step IV, the filling may adhere to the outside of the sealing position of the bag mouth. If there is any extraneous matter at the sealing position, it causes a poor sealing at the time of sealing, so it is necessary to remove this.

FIG. 4 shows a conventional method for removing extraneous matter adhering to a bag mouth. After a rod 8 having an air outlet is inserted into the bag 1 from the bag mouth, compressed air is supplied from an air hose 9. The air is blown upward to blow air, and the attached matter such as the filler attached to the bag mouth is blown off and removed. The air is also blown from the outside in the same manner to remove extraneous matter adhering to the outside.

[0005]

However, in the conventional method described above, since the compressed air is blown outward from the inside of the bag, the inside of the bag becomes negative pressure and the bag mouth is closed, so that the entire bag mouth is closed. It is not possible to remove the extraneous deposits. Further, there is a problem that the adhered substance is blown outward and adheres to surrounding machines and devices, another bag and the like, and becomes soiled.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is characterized by a rod which is pivotally supported by a base and swings right and left by a driving mechanism. And a scrubber that is attached to the tip of the bag and that contacts the seal portion of the bag before sealing in which the filler is stored and removes the adhered material attached to the seal portion.

[0007]

[Function] When the main body is swung right and left, the swabbing part at the tip contacts the seal part of the bag and swings right and left.
Deposits adhering to the seal portion are removed by being wiped off.

[0008]

1 and 2 show the device of the present invention.
Is a plan view and FIG. 2 is a side view. As shown in the above drawing, the attached matter removing device of the present invention supports the base of the rod 4 on the frame base 7 via the shaft 6 and arranges a fork 3a of a fixed length at the tip of the rod 4 at an appropriate interval. The scraping body 3 is formed to be protruded, and the scraping body 3 is above the fixed height of the bag gripping claws 2a, 2b by the operation of a drive mechanism (not shown) via a rod 5 at the intermediate portion of the rod 4. At the position, the left and right swinging operations of arrows (a) and (b) are performed toward the table T side.

The adhering substance removing apparatus having the above-described structure is installed at an intermediate position between the filling step V and the sealing step VI of the rotating table T or at a position just before the sealing step VI. When the stored bag 1 is sent to the sealing step VI, a driving mechanism (not shown) is associated with this.
The rod 5 performs the swinging movement of the rod 4 (a) and (b) through the above, so that the fork 3a of the scraping body 3 comes into contact with the seal portion 1a of the bag 1, and the portion is moved inward. Therefore, the adhered matter such as the filler adhered to the inside of the seal portion 1a or the inside and outside of the bag mouth is wiped off and removed.

Thus, the bag 1 is sent to the first and second sealing steps VI and VII to seal the bag opening. At this time, the attached matter attached to the seal portion 1a is completely removed. Therefore, a good sealing operation without sealing failure is performed. It should be noted that the number of times of the sweeping operation, the operating speed, and the like are appropriately determined according to the situation of the attached matter.

[0011]

The present invention is constructed as described above. Since the rod 4 is used for swinging operation and the bag mouth is swung while being sandwiched by the fork scraping body 3, the seal portion 1 is formed.
The substance adhering to a can be efficiently removed completely and removed. Therefore, in the subsequent sealing step VI, a good sealing action without defective sealing is performed on the bag.
