Abstract

(57) [Summary] [Objective] The purpose is to remove the adhering matter that has adhered to the bag opening before sealing, which contains the filled material, so as to prevent defective sealing. [Structure] The base is pivotally supported, and a rod that is rotated left and right by a drive mechanism and a seal part of a bag before the seal that is attached to the tip of the rod and contains a filling material are in contact with and attached to the seal part. It consists of a wiper that removes the deposits.

[Industrial application]

 TECHNICAL FIELD The present invention relates to a bag deposit removing device for removing deposits adhering to a bag opening before sealing, in which a filling is stored.

[0002]

[Prior Art]

 As shown in FIG. 3, the basic packaging system of an automatic packaging machine for foods and the like sucks the bag 1 in the bag storage device by the suction cup 11 of the bag feeding device A and lifts it, and the chuck of the gripping device B on the table T side. Bag feeding step I to deliver to the bag 10, 10, marking step II for marking the production date of food with the marking device C on the surface of the grasped bag 1, and the suction cup 12 of the bag opening device D for opening the mouth of the bag 1. Opening bag step III, filling steps IV and V for filling the bag 1 with filling material and filling liquid by the filling device E, primary sealing step VI and secondary sealing step for sealing the bag mouth with the sealing device F VII, a discharging step VIII for discharging the packaged bag 1 to the next step, and the like.

In the above packaging system, the bag 1 containing the filling material and the filling liquid in the filling steps IV and V is sealed at the bag mouth in the sealing steps VI and VII. When filling in, the filling may adhere to the inside and outside of the sealing position of the bag mouth. It is necessary to remove the foreign matter on the seal position, as it may cause a defective seal during sealing.

FIG. 4 shows a conventional method for removing deposits adhering to the bag mouth. After the punch 8 having an air outlet is inserted into the bag 1 from the bag mouth, compressed air is blown from the air hose 9. The air is blown out and blown upward, and the adhering substances such as fillers adhering to the bag mouth are blown off and removed. In addition, air is also blown from the outside in the same manner to remove the deposits adhering to the outside.

[0005]

[Problems to be Solved by the Invention] However, in the above-described conventional method, since compressed air is blown outward from the inside of the bag, the inside of the bag becomes a negative pressure and the bag mouth is closed, so that the entire bag mouth is closed. Removal of deposits across the area will not occur. In addition, there is a problem that the adhered matter is blown out to the outside and adheres to the surrounding machines and devices, another bag, etc. to be contaminated, and there is a defect that the adhered matter having a particularly high viscosity has no effect.

[0006]

[Means for Solving the Problems]

 The present invention is intended to solve the above problems, and is characterized in that a base is pivotally supported, and a rod that is rotated left and right by a drive mechanism and a filler that is attached to the tip of the rod are provided. It is composed of a blow-off body that comes into contact with the seal portion of the stored unsealed bag and removes the deposits attached to the seal portion.

[0007]

[Action]

 When the main body is rotated to the left and right, the expulsion part at the tip comes into contact with the seal part of the bag and swings it to the left and right, so that the adhered matter adhering to the seal part is dislodged and removed. .

[0008]

【Example】

 1 and 2 show the device of the present invention. FIG. 1 is a plan view and FIG. 2 is a plan view. As shown in the above drawings, the deposit removing device of the present invention pivotally supports the base of the rod 4 on a frame base 7 via a shaft 6, and forks 3a of a certain length on the tip side of the rod 4 at appropriate intervals. It is formed on the ejecting body 3 which is protruded, and the rod 5 is interposed in the middle portion of the rod 4, and the ejecting body 3 is operated by a drive mechanism (not shown) so that the bag grasping claws 2a, 2a have a constant height. At the upper position, the front and rear swinging action of the arrows (a) and (b) toward the table T side is performed.

The deposit removing device having the above configuration is installed at an intermediate position between the filling process V and the sealing process VI of the rotating table T or at a position before the sealing process VI. When the stored bag 1 is sent to the sealing step VI, in connection with this, the connecting rod 4 moves the rod 1 through the drive mechanism (not shown) to move the rod 1 forward and backward. As a result, the fork 3a of the scrubbing body 3 comes into contact with the seal portion 1a of the bag 1 and swings back and forth while pinching the portion inside the seal portion 1a. Adhesives such as fillers adhering to the inside and outside of the mouth are wiped off and removed.

Then, the bag 1 is sent to the first and second sealing steps VI and VII to be sealed at the bag mouth. At this time, the adhered matter adhered to the seal portion 1a is completely removed. Since it has been removed, a good sealing work can be performed without a defective seal. Note that the number of times the cleaning operation is performed, the operation speed, and the like are appropriately determined according to the condition of the adhered matter.

[0011]

[Effect of the device]

 The present invention is configured as described above. Since the rod 4 is swinging and the bag mouth is swung in a state of being sandwiched by the fork scraping body 3, the adhered matter attached to the seal portion 1a is removed. It can be removed efficiently and completely. Therefore, in the subsequent sealing step VI, the bag has a good sealing action without a sealing defect.
