Description

[Detailed Description of the Invention] The present invention relates to a packaging device, in which a packaged article such as a leaf vegetable that is difficult to shape for filling by a machine is placed on a splint above its lower end at the filling position. The splint is filled into the packaging bag along with the packaged goods, and in conjunction with the filling, the packaging bag and the packaged goods are gripped by a pair of presser plates below the lower end of the splint, and only the splint that has escaped the gripping is held. It is designed to release by rising, and its purpose is to store packaged items with unique characteristics such as Enoki mushrooms, leafy vegetables, and other items that are difficult to shape or easily damaged if filled alone. To provide a packaging device which can easily perform mechanical filling of packaging bags without causing damage.

An embodiment of the present invention will be described.

In the figure, reference numeral 1 denotes a table, and the table of the packaging device has a pair of gripping arms 2 protruding radially from an intermittent rotating plate on its upper surface to grasp the vertical edge of the packaging bag a and support it in a hanging manner. The stopping position of the first packaging bag a is defined as the filling position I of the packaged article, and a pair of suction cups 3a and 3b are installed at this position to suck both sides of the packaging bag a near the bag opening to widen the bag opening. Movable arm tube 4a.

4b.

Further, above the bag opening, there is a shaping plate 5 whose inner surface is shaped like an arc,
A splint plate 6 made of a vertically long flexible plate material and having vertical edges 7 on both sides in contact with each other is provided facing the inner surface of the shaping plate 5.

The splint plate 6 and the shaping plate 5 are curved in a concave arc shape so as to form a cylindrical inner space 8 between their inner surfaces, and the shaping plate 5 is attached to a horizontal link 9 that moves back and forth, and the splint plate 6 is vertically long. is attached to the slider 10 that moves up and down.

Before supplying the packaged articles, the horizontal link 9 moves backward to retract the shaping plate 5 and enlarge the cylindrical interior space 8 as shown by the solid line in FIG.

The splint plate 6 stops with its lower edge slightly above the lower edge of the shaping plate 5 due to the upward movement of the slider 10.

Immediately below the shaping plate 5, a shutter 11 is provided which performs a sideward retracting movement during the feeding movement of the packaged articles performed by the downward movement of the slider 10 and the splint plate 6.
1 is provided with an inverted conical guide cylinder 12 that fits slightly from the position shown in FIG.

As shown in FIG. 3, the guide tube is constituted by a vertically divided tube that opens left and right when the splint plate 6 is lowered to expand the bag opening of the packaging bag a from the inside. When it is rising, it closes in an inverted cone shape by means of springs, etc.

On the table 1, as shown in FIG. 3, shafts 13a and 13b corresponding to the lower sides of the packaging bag a are fixed, and a pair of presser plates 14a and 14b corresponding to both sides of the packaging bag a are attached to each shaft.
The lower ends of each are fitted to rotate freely, and sector gears 15a and 15b that mesh with each other are fixed to each lower end, and elastic and flexible holding pieces 16a and 16b, such as sponge plates, are attached to the upper ends. The presser pieces 16a and 16b are brought into contact with the lower both side layers of the packaging bag a.

Further, an arm 17 is protruded from one of the presser plates 14a, and the upper end of a connecting rod 18 that causes vertical movement by a rotary cam plate (not shown) on the lower surface of the table 1 is pivotally connected to the arm. The opening and closing movements of the holding pieces 16a and 16b are performed, and the opening movement shown by the chain line and the closing movement shown by the solid line are performed downward in conjunction with the meshing of the sector gears 15a and 15b.

In the apparatus of the above embodiment, as shown in FIG. 1, when the shaping plate 5 retreats and the lumbar support plate 6 rises and stops, the packaging bag a held and suspended by the pair of gripping arms 2 moves to the supply position I.
Then, the movable arm tubes 4a and 4b move forward from the retreated position and suck the packaging bag a by the suction cups 3a and 3b.
Touch both sides of the bag near the mouth of the bag and step back a little while suctioning to expand the bag mouth (at the same time, the pair of gripping arms 2 narrows the gap a little), and then the guide tube 12 moves down a little to make the bag as shown in Figure 3. Insert the bottom edge slightly into the bag opening.

On the other hand, immediately after the splint plate 6 stops rising, the packaged articles such as Enoki mushrooms and leafy vegetables are pressed against the concave arcuate inner surface of the splint plate 6, and the diameter is expanded as shown by the solid line in Figure 2. The lower end is brought into contact with the shutter 11 by pushing it into the cylindrical inner space 8.

When this feeding is completed, the horizontal link 9 advances to the right in FIG. 1, and causes the vertical flames 7 on both sides of the splint plate 6 to slide relative to each other on the arcuate inner surface, as shown by the chain line in FIG. The container is deformed into a cylindrical shape with a small diameter, and the packaged article sent into the cylindrical inner space 8 is centripetally compressed and gripped.

At that time, the shutter 11 is laterally withdrawn from the lower surface of the interior space 8, and the slider 10 begins its downward movement, lowering the splint 6 which grips the packaged article.

The splint plate 6 expands the guide tube 12 as shown in FIG. 3 and descends from the bag opening of the packaging bag a to the position approximately shown in FIG. retract, thereby releasing the compression of the splint 6.

At this time, the presser plates 14a and 14b move from the open position shown by the chain line in FIG. 3 to the closed position shown by the solid line, and the presser piece 16a.

16b, both sides of the packaging bag a and the packaged article are brought into contact with just below the lower end of the splint plate 6 and are engaged.

Immediately after the latching operation, the splint plate 6 returns to the raised position together with the slider 10, and lifts up and escapes from the packaging bag a while leaving the packaged articles in the packaging bag a.

After that, the suction cups 3a and 3b whose suction ability has been canceled are evacuated,
The shaping plate 5 retreats again to the position shown in FIG. 1, the guide tube 12 rises a little, the holding plates 14a and 14b open to release the jamming, and the shutter 11 moves back, causing the packaged article to be wrapped. If the inside of bag a is not falling enough, press the presser plate 1.
Along with the above-mentioned release movement of 4a and 14b, a re-fall occurs.

The packaging bag a moves to the next position together with the pair of gripping arms 2.

As exemplified above, the present invention is arranged in the filling position of the packaging device, in the opening of the packaging bag gripped by both longitudinal edges by the pair of gripping arms, and placed above the lower end of the packaging article together with the packaging bag. a splint that enters and moves upward; performs opening and closing movements on both sides of the packaging bag, and grips the packaging bag and the packaged article under the splint as the packaged article is fed into the packaging bag; A pair of presser plates are installed; the upward movement of the splint plates is made to occur after the gripping, and when used alone, it is difficult to shape and fill packaging bags, and packaging articles that are difficult to fill and easily cause damage. The material is attached to the splint above the filling position to facilitate shaping, and is also fed into the opening of the packaging bag together with the splint to prevent damage. Therefore, the packaging bag and the packaged article are held down by a pair of pressing plates below the splint plate, which has the effect of speeding up the filling of the packaging bag with the packaged articles of the above-mentioned properties.
