Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a novel proposal for an apparatus for inserting objects to be filled into packaging bags.

(Prior Art) Conventionally, in the filling and packaging of foods, filling hopper 1'
to allow the material to be filled 2' to fall naturally into the packaging bag 3'.

(Problems to be Solved by the Invention) By the way, when the material is added using the gravity drop method, it falls into a lump at the bottom of the bag, and if it is welded and sealed in that state, the product will have a poor appearance.

In particular, in vacuum packaging bags that are deaerated and vacuum welded, it is impossible to align the filling after filling and sealing, so it is strongly desired that the bags be inserted in an orderly and preferable manner.

Furthermore, if the soft material is filled using the dropping method, the product may lose its shape and become unusable.

(Means for Solving the Problems) The present invention solves the above problems and makes it possible to obtain high-quality packaging bags. The bag openings of each packaging bag are placed in the same direction through the fixing gripping claws, and are moved intermittently at the above-mentioned pitch intervals. On the other hand, on the side of the conveyance belt perpendicular to the bag opening to be opened, a supply tray for filling material having a U-shaped cross section is connected to a piston rod of a reciprocating cylinder; In connection with the stop due to intermittent movement, the supply tray for the material to be filled is inserted into the opened bag mouth, and on the other hand, the supply tray for the material to be filled is inserted into the bag mouth on the supply tray for the material to be filled. A pushing rod is provided to push the material on the supply tray for filling into the bag by interlocking and swinging by cylinder operation, and a push rod is provided above the packaging bag to be opened on the conveyor belt. The device is characterized in that a pressing plate with sponge rubber adhered to the lower surface thereof is configured to interlock with the pushing rod and move up and down by cylinder operation.

(Example) FIG. 1 is a partial perspective view of an insertion device according to the present invention.

Reference numeral 1 denotes a supply tray which is slidable in the horizontal direction and has a U-shaped cross section, a beak-shaped tip 1a, and a rear end connected to a piston rod 2a of a cylinder 2. 3a and 3b are guide rails, and 4a and 4b are sliding members provided on the lower surface of the supply tray 1 that engage with the guide rails.When the piston rod 2a is pushed out by the operation of the cylinder 2, it moves a certain distance, It is adapted to move forward to the mounting position of the packaging bag 5.

Here, the packaging bag 5 is arranged horizontally,
6a and 6b are fixing gripping claws, and 7a and 7b are opening suction cups.

Reference numeral 8 denotes a pushing means disposed above the opening side of the packaging bag 5, which consists of an L-shaped lever 8b that swings by the operation of a cylinder 8a, and a pushing rod 8c attached to the tip of the lever 8b; is a support shaft of the L-shaped lever 8b.

Reference numeral 10 denotes a pressing means disposed above the packaging bag 5, which includes a cylinder 10a and the cylinder 10a.
It consists of a piston rod 10b that swings when the piston rod 10b is operated, and a pressing plate 10c attached to the tip of the piston rod 10b. Sponge rubber S is adhered to the lower part of the pressing plate 10c. Note that 10d is a guide bracket.

FIG. 2 is an explanatory diagram of the operation, and the illustrated example shows the packaging bag 5.
A large number of bags (5, 5', 5'', etc.) are installed at a uniform pitch p so that each bag opening is on the same side with respect to the width direction of the conveying belt 11, and the conveying belt 11 is moved intermittently at the pitch interval p. At this time, the opening of the packaging bag 5 is opened by the operation of the suction cups 7a and 7b during the intermittent movement process, and the supply tray 1 is loaded with the material to be filled 12. In this state, the object to be filled 12 is inserted by moving toward the inside of the bag mouth.

Specifically, the cylinder 2 is moved forward toward the opening of the packaging bag 5 by the operation of the cylinder 2, and the object to be filled 12 on the tray is inserted into the bag, and when the insertion is completed, the cylinder 2 is activated. The pushing rod 8c pushes the material 12 on the tray into the bag through the lever 8b, and then the supply tray 1 escapes from inside the bag, but at this time the cylinder 10
a is activated and presses the press plate 10 via the piston rod 10b.
C is lowered and the top surface of the packaging bag 5 is pressurized by the sponge rubber s of the plate, so that the object to be filled 12 is prevented from shifting and its shape is not lost. Subsequently, the bag opening is sealed by a sealing means (not shown).

(Effects of the invention) According to the invention, the objects to be filled are aligned and arranged on a horizontal supply tray and then inserted into the packaging bag, and at that time the pushing rod is operated to ensure that they are pushed into the packaging bag. At the same time, the upper surface of the packaging bag is pressed by a pressing plate after being pushed in, thereby preventing the supply tray from losing its shape during the pulling operation.
This results in a beautiful packaging finish.

In the illustrated example, one insertion device is provided, but in actual work, several insertion devices are arranged in parallel at pitch intervals of a packaging container, and these devices are moved intermittently as a constituent unit of one block. The overall filling time can be shortened and productivity can be improved.

Claims (1)

[Scope of utility model registration request] Each bag opening of the packaging bag is placed in the same direction through fixing gripping claws attached at uniform pitch intervals in the width direction of the conveyance belt, and the bags are moved intermittently at the pitch interval. At the same time, the bag opening of each packaging bag is opened by the operation of the upper and lower suction cups, and on the other hand, a supply tray for the stuff to be filled having a U-shaped cross section is provided on the side of the conveyance belt perpendicular to the bag opening to be opened. It is connected to a piston rod of a reciprocating cylinder, and when the conveyor belt is stopped due to intermittent movement, a supply tray for the material to be filled is inserted into the open bag mouth, and on the other hand, a supply tray for the material to be filled is inserted into the opening of the bag. In this case, the supply tray for the material to be filled is inserted into the bag opening. A pushing rod is linked and swings by cylinder operation to push the material on the supply tray for the material to be filled into the bag. A pressing plate with sponge rubber adhered to the lower surface of the conveying belt above the opening of the packaging bag is configured to be moved up and down by cylinder operation in conjunction with the pushing rod.
