Longevity Packing Machine {APPARATUS FOR WRAPPING ELONGATED OBJECT}

The present invention relates to a long object packing machine, and more particularly, a long bag (long) vegetables, such as asparagus, leek, burdock or yam, which is difficult to pack, in particular a flexible packaging bag, for example For example, the present invention relates to a long product packing machine which can be reliably introduced by a simple operation in a plastic packaging bag.

Vegetables sold in supermarkets, for example eggplants, cucumbers, asparagus, green onions, burdock, yams, etc., are put in packaging bags made of transparent plastic films and displayed on shelves. Packaging of these vegetables is carried out in the process from the producer to the supermarket, etc., and is performed by hand. Among these packaging operations, particularly long vegetables, such as asparagus, green onion, burdock or yam, are made of plastic flexible, transparent, and long, which are difficult to open at the opening of the bag. In addition, even when the long vegetables are put from the inlet of the bag, the long vegetables are caught in the middle of the bag and cannot be smoothly fed to the bottom. Thus, the packing work of these long vegetables took a lot of effort and time.

Many packaging machines and packaging bags have been proposed so far in order to alleviate the cumbersome work of such packaging.

As a packaging machine, several storage bags for accommodating goods are arrange | positioned in the substantially cylindrical-shaped support frame arrange | positioned inclined like the Japanese Unexamined-Japanese-Patent No. 1-1-1216216 (refer FIG. 2, FIG. 2), A rotatable opening plate for installing the opening operation mechanism for sequentially opening the insertion opening of the storage bag in the support frame and entering the opening operation mechanism into the insertion opening of the storage bag, and rotating the opening plate; The packaging machine comprised with the rotation operation lever is known.

The hopper introduction mechanism 20 includes a lift lever 21 fixed to the support 40 so as to be movable in the vertical direction, a hopper 23 fixed to one end of the lift lever 21, and a lift lever 21. It consists of an operation lever 21a connected to the other end.

The lifting lever 21 is slidably held in the vertical direction by sliding grooves formed by L-shaped frames 42a and 42b provided on the rear surface of the support body 40. In addition, the lower part of the elevating lever 21 has a substantially L-shape in which the elevating lever 21 is installed at an oblique angle with a slight oblique angle so that the elevating lever 21 is brought into contact with the rotating body 39 when the operating member 34 is lifted.

In addition, the lifting lever 21 is provided with an arm 21b protruding at a right angle in a direction opposite to the operation lever 21a, and a hopper 23 is provided on the arm 21b.

The hopper 23 forms a long cylindrical shape having a diameter into which a long object can be packaged, and is divided into a cylindrical cylindrical body 24 and a plurality of slits in the longitudinal direction from one end of the cylindrical body 24. a plurality of strip (短冊: jobut of paper) is formed of a cylindrical body 25 made of a thin piece (25 _{1-25 10)} of the contour. The length of the thin strip pieces (25 _{1-25 10)} of the shape is, but set to an appropriate length by the length of the packaging bag P that the packaging is stored, where the first amount of at least 3 minutes from the inlet to the bag during infusion of blood packaging It is desirable to reach to. Moreover, this thin piece may be formed integrally or separately with the cylinder 24. However, it is preferable that the thin strip of the single-shape shape is formed of a flexible material. As the flexible material, for example, a plastic material is used. In addition, the material of a single piece of thin piece is not limited to this.

The hopper 23 is composed of a plurality of single-shaped thin pieces 25 _{1 to} 25 ₁₀ divided into a plurality of slits, so that when a packaged object passes through the hopper 23 and is put into a packaging bag, it is usually Although the place where the air in the packaging bag escapes is lost, it becomes the obstacle of the input of the packaged object, but by forming a plurality of slits, the remaining air can pass through the slit and go out, thereby making it easy to inject.

Barrel-shaped body 25 made of a thin piece of the plurality of band-shaped, thin slices of the plurality of strip-like (25 _{1-25 10)} is so separated by the slit, the distal end (25a) sealing the entrance of the packaging pouch In order to insert into the tube, a convergence mechanism for tying the tip portion 25a of the tubular body 25 is required.

This procedure mechanism has scattered horns in a state where the tubular body 25 composed of a plurality of strip-shaped thin pieces is lifted upward, that is, before the tip portion 25a is inserted into the bag inlet 56. A plurality of strip-shaped thin pieces (25 _{1 to} 25 ₁₀ ) are relatively tightly tapered to facilitate the insertion into the bag inlet 56, and the tip portion 25a of the tubular body is inserted into the bag. Therefore, a mechanism for weakening the binding force and making it easy to insert the packaged object is preferable.

5 is an example of this procedure mechanism. This convergence mechanism 81 consists of a loop ring 82a which binds a plurality of single-shaped thin pieces 25 _{1 to} 25 ₁₀ , and an adjusting member 83 for adjusting the convergence force of the convergence mechanism 81. The loop ring 82a is inserted into the hole 40a of the support body 40 by using one thread-shaped body 82 having a predetermined length, and the loop ring 82a is formed by making the center part annular. The diameter of the loop ring 82a is reduced or enlarged by pulling or loosening the other end 82b of the yarn-shaped body 82 from the back surface of the support body 40. The weight of the loop ring 82a is reduced or enlarged at a predetermined convergence force by using a weight for such an adjustment member 83 for pulling or relaxing. Wire, nylon cord, etc. are used for the yarn-shaped body 82. That is, in this convergence mechanism 81, it is installed in the vicinity of the holding port 50 of the support body 40, and the adjustment member 83 is drooped down through the loop ring 82a, and the loop ring 82a is a hopper. It is pulled by the adjustment member 83 according to the up-down movement of 23, and is reduced or expanded in diameter.

In addition, the adjustment member 83 of the convergence mechanism 81 may be provided on the surface of the support body 40 as shown in FIGS.

The sealing opening mechanism 60 includes an approximately L-shaped actuating lever 61, an adhesive member 62 fixed to the tip of the actuating lever 61, and a rotating body fixed to the lower end of the actuating lever 61. It consists of 63, and the edge part of the L-shaped actuating lever 61 is supported by one support | pillar 32a at the point 61c. The L-shaped actuating lever 61 is composed of a long side lever 61a and a short side lever 61b, and supports an adhesive member 62 at the front end of the long side lever 61a so as to be parallel to the support 40. At 62a, rotation is freely fixed. Moreover, the rotating body 63 is provided in the front-end | tip of the short side lever 61b. An annular roll is used for the rotating body 63.

The adhesive member 62 is formed of a roll having a length approximately equal to the width of the packaging bag, and an adhesive material 62b mounted on the roll, and is formed by a long side lever (B) by a support shaft 65 parallel to the packaging bag. It is detected at the tip of 61a). The adhesive material 62b is attached to the surface material of the packaging bag, can be easily peeled off, and a reusable adhesive such as PVA (polyvinyl alcohol) is used. By using such an adhesive agent, when adhesive force falls, the adhesive force is restored by washing an adhesive surface with water, and it can aim for reuse.

When the adhesive member 62 is freely rotated at the tip of the long side lever 61a, the opening and closing of the bag opening is simplified because the adhesive member 62 is freely attached to the thin and flexible packaging bag. Moreover, when a roll rotates, the place where an adhesive material is affixed will move, and an adhesive material can be used for a long time. In addition, since the adhesive member 62 rotates when the packaging bag is pulled out, the opening of the sealing inlet 56 is facilitated.

It is necessary for the adhesive member 62 to maintain this opening state until the sealing inlet 56 is opened to inject the packaged object. In order to maintain this state, the adjustment member 64 which regulates the swing range of the long side lever 61a is provided in the support | pillar 32a. For example, an L-shaped bracket is used for the adjustment member 64 as a whole having an adjustment groove.

4 is an explanatory view of the operation of the rotating body 63 provided in the cam mechanism 38 of the operation member 34 and the short side lever 61b of the sealing inlet mechanism 60 engaged with it.

The cam mechanism 38 (FIG. 4 (A)) which was in the stop position engages with the rotating body 63 in accordance with the rotation upward of the operating member 34. When the rotation of the operating member 34 is further advanced, the cam The mechanism 38 pushes the rotating body 63, and the lever 61 starts to rotate in the clockwise direction about the point 61c (FIG. 4B). The shape of the cam 38 is S-shaped, E-shaped, or Japanese-shaped, and since the middle portion is supported, the lower end of the cam 38 has a lower end even if its upper end is engaged with the rotating body 63. The lever 61 is interlocked because it cannot rotate by being engaged with the support of (38) (Fig. 4 (c)). When the hopper 23 moves upward to reach a predetermined position and the rotating body 63 rides over the cam 38, the engagement of the rotating body 63 is suddenly released, and the adhesive member 62 is attached to the packaging bag 53. ), The lever 61 which affixed () is retracted from its weight to the original position supported by the adjustment member 64, and opens the sealing inlet 56. As shown in FIG. The cam 38 has no engagement with the support of the cam 38 in the return path, i.e., the cam 38 only performs the rotational movement even if the cam 38 is forced in the counterclockwise direction in the drawing. The rotating body 63 smoothly returns to its original position without disturbing the cam 38. (FIG. 4D). The operation member 34 also pushes up and down the lift lever 21 until the hopper 23 and the cylindrical body 25 reach a predetermined position. (FIG. 4E).

Next, the operation | work encapsulating the packaged object to this packaging machine is demonstrated with reference to FIG. In addition, FIG. 3 is an operation | movement figure demonstrated using the side view of the packaging machine of FIG. 1, 2. In the following description, the code | symbol which is not attached to FIG. 3 uses another thing of FIGS.

First, the operation lever 36 is pushed down like an arrow. When the operation lever 36 is pushed down, one end 34b of the operation member 34 is lifted, so that the rotating body 39 moves in a rolling motion along the lower surface of the operation lever 21a to push the lifting lever 21. It raises (FIG. 3 (A), (B)).

When the operation lever 36 is pushed further down, the hopper 23 moves upward with the lifting lever 21 so that the tip portion 25a rises above the front portion of the packaging bag 53 and the tip portion 25a. Is tapered at the ends by the loop ring 82a of the procedure mechanism. Simultaneously with this, the actuating member 34 is further lifted so that the encapsulation inlet opening mechanism 60 rotated about the point 61c through the rotating body 63 engaged with the cam 38 of the actuating member 34. ), The adhesive member 62 provided at the free end thereof is affixed near the bag inlet 56 of the packaging bag 53, and then the engagement of the rotating body 63 is released to release the lever ( 61 retreats and opens the sealing inlet 56 (FIG. 3C).

Therefore, the tip 25a of the hopper 23 is raised above the bag inlet 56 by pushing the operation lever 36 downward, and the bag inlet 56 of the packaging bag 53 is opened. do. The lever 61 is stopped at a predetermined position by the adjustment member 64, and the sealing inlet 56 is kept open.

Then, the operation lever 36 is lifted upwards as shown by the arrow. By this lifting, the operation member 34 gradually starts to descend, and the tip 25a of the hopper 23 is inserted into the bag 56 in accordance with the lowering. At this time, since the tip portion 25a of the hopper is tied and tapered, the insertion into the bag inlet 56 is performed smoothly. (FIG. 3D).

In addition, when the operation lever 36 is lifted up, the tip portion 25a of the hopper 23 enters the packaging bag, and at the same time, the thin end of the tip portion is gradually enlarged and opened.

In this state, a long packaged object is thrown from the cylinder 24 of the hopper 23. Then, the packaged object falls along the inner circumferential surface of the hopper 23 by its own weight, enlarges and opens the tip portion 25a of the hopper 23 and is stored in the packaging bag 53. (FIG. 3E).

Thereafter, the packaging bag 53 containing the packaged object is pulled away from the holder 50. (FIG. 3F). By this detachment, the packaging bag 53 is separated from the holding device 50 at the same time as the upper edge portion is peeled off from the adhesive member 62 and broken from the sewing stitches 57'a and 57'b (see Fig. 6).

This packing machine raises the hopper by pushing down the operation lever, and in conjunction with this, opens the bag inlet by the bag inlet opening mechanism, inserts the tip of the hopper into the bag inlet, and in this state removes the package from the other end of the hopper. It can be put in, so that the packaging bag can be filled smoothly. Even if the packaged object is a long vegetable, it is difficult to put it in a relatively short one, for example, asparagus, or a long one, for example, a long one such as leek, burdock, or yam, and the tip of the hopper is wrapped. Because of the short length, it is easy to fill the bag with long vegetables that were difficult to induce smoothly into the bag.

8 and 9 show a packaging machine of a second embodiment of the present invention, FIG. 8 is an external perspective view of the packaging machine, and FIG. 9 is an operation explanatory view of the packaging machine of FIG. 8.

This packaging machine 10A has an operation having a hopper introduction mechanism 20A having a hopper for inserting a packaged object into one end of the bag when the packaged object is inserted, and an operation lever for moving the hopper up and down. 30 A of mechanisms, and the sealing inlet opening mechanism 60A which opens the sealing inlet of the packaging bag attached to the support body in conjunction with operation of this operation lever. In addition, since this packing machine 10A has a structure substantially the same as the above packing machine 10, the common part uses the same number as the packing machine 10, abbreviate | omits duplication description, and demonstrates another structure in detail.

30 A of said operating mechanisms consist of the plate-shaped member 93 standing up from the other end 31b of the base stand 31, and the operation lever 91 fixed to the upper end part 92 of this plate-shaped member 93. As shown in FIG. .

The actuating lever 91 is bent almost in a U shape using a pipe material, and the U-shaped bottom portion 91a is installed below the actuating lever 21a of the lifting lever 21, and the U-shaped open end is It is rotatably fixed to the upper end 92 of the plate-shaped member 93 by a holding | gripping tool. In addition, approximately the center portion 91b of the actuating lever 91 is connected to the other end of the connecting rod 35 having one end coupled to the actuating lever 36.

By setting the operation lever 91 in the above-described configuration, when the operation lever 36 is pushed down like the operation member 34 of the first embodiment, the upper end point 92 is moved to the shaft point. As a result, the U-shaped bottom portion pushes the elevating lever 21 upward to raise the hopper 23, but the cam mechanism or the like is unnecessary as compared with the operating member 34, and the mechanism of the operating member is simplified. In addition, the structure of the lifting lever 21 is simplified.

In addition, the operating lever 36 is provided with a rotating body 70 through the connecting member 71 at the lower portion near the tip end thereof. When the operation lever 36 is pushed down, this rotating body 70 abuts against the tongue piece 72 of 60 A of sealing inlet opening mechanisms, and contact | connects the sealing inlet. Complete the function of opening.

The structure of the hopper 23 is the same as that of the 1st Embodiment of the said hopper introduction mechanism 20A, but the installation place of the loop ring 82a of the convergence mechanism 8l differs. That is, in 1st embodiment, although the loop ring 82a is in the position of the cylindrical body 25 which consists of the single-piece thin pieces of the hopper 23, in this 2nd embodiment, the outer periphery of the cylindrical body 24 is carried out. Place it in In accordance with this position change, the position at which the thread-shaped body 82 is provided on the support body 40 is set upward.

By changing this installation location, the up-and-down movement of the hopper 23 becomes smooth, and the convergence of the front-end | tip part 25a of several strip | belt-shaped thin pieces becomes smooth.

In addition, the support member 40 has a surface member 54 of the packaging bag 53 bonded to the adhesive member 62 in order to ensure the opening of the sealing inlet 56 of the packaging bag 53 hanging on the holder 50. Is attached, and the stopper 80 which suppresses the movement of the back surface material 55 and facilitates the opening of the sealing inlet is provided.

Moreover, as for the sealing inlet opening mechanism 60A, the tongue piece 72 facing obliquely downward in the vicinity of the front-end | tip part of the operation lever 61, ie, the location where the adhesive member 62 is attached, is a near point of the front end of the operation lever 61. Is installed using. Hinges and the like are used for this holding member.

This tongue piece 72 has a predetermined length, and when the operation lever 36 is pushed down, the rotating body 70 pushes down the upper surface of the tongue piece 72 while moving downward, thereby actuating it. Through the lever 61, the adhesive member 62 is moved in the direction of the surface material of the packaging bag (not shown) and adhered.

When the rotor 7 passes through the tip portion 72a of the tongue 72, the rotor 70 moves to the lower surface of the tongue 72, and then lifts the operation lever 36 upward to rotate the rotor ( 70 lifts end 72a of tongue piece 72. Because of this lifting, the tongue piece 72 is held at the distal end of the actuating lever 61, so that the end portion 72a of the tongue piece 72 is lifted up to a predetermined position by the rotating body 70. The tip of the end portion 72a of the tongue piece 72 slips off the rotor 70 at the position beyond the position of. Thereafter, the rotating body 70 supports the operation lever 61 by lifting the tongue piece 72, and the adhesive member is affixed to the surface material of the packaging bag, and is slowly inclined in the direction of enlarging the bag entrance with the adhesive member attached. The bag opening is opened after a predetermined time. Since the opening of the sealing is opened slowly by this opening operation, breakage of the sealing body and the like at the time of opening can be eliminated as compared with the adhesive member falling immediately after being attached.

Next, the operation | work encapsulating the packaged object to this packaging machine is demonstrated with reference to FIG. In addition, FIG. 9 is demonstrated using the side view (FIG. 9 (A)) of the packaging machine of FIG. 8. In the following description, the code | symbol which is not attached to FIG. 9 uses the thing of FIG. In addition, description of the part common to what was described in 1st Embodiment is abbreviate | omitted.

First, the operation lever 36 is pushed down in the direction of the arrow. When the operation lever 36 is pushed down, the U-shaped bottom portion 91a is engaged with the operation lever 21a with the upper end 92 as an axis point, and the lifting lever 21 is pushed upward to raise the hopper ( 23 is raised, whereby the tip portion 25a of the hopper 23 is tapered to the end by the loop ring 82a of the converging mechanism on the cylinder 24. At the same time, the rotary body 70 through the connecting member 71 at the distal end of the operating lever 36 is pushed down while rolling the surface of the tongue piece 72, and is thus bonded through the operating lever 61. The member 62 is moved in the direction of the surface material of the packaging bag 54 to be adhered. ((B), (C) of FIG. 9).

After the adhesive member 62 is adhered to the packaging bag 53, when the operation lever 36 is further pushed down, the rotating body 70 passes through the tip portion 72a of the tongue piece 72. (FIG. 9D). At this time, the rotating body 70 moves to the lower surface of the tongue piece 72. Then, when the operation lever 36 is lifted upward, the rotating body 70 lifts the tip portion 72a of the tongue piece 72. (FIG. 9E). By this lifting, since the tongue piece 72 is held by the tip end of the operation lever 61, the tip part 72a of the tongue piece 72 is lifted to a predetermined position by the rotating body 70, and a predetermined position is carried out. The tip end of the tip end portion 72a of the tongue piece 72 slips off the rotating body 70 after passing through. (FIG. 9F).

At this time, the rotating body 70 lifts the tongue piece 72, thereby supporting the operation lever 61, and the adhesive member is affixed to the surface material of the bag, and is slowly attached in the direction of enlarging the bag inlet with the bag attached. Tilt opens the opening of a bag for a predetermined time. Lifting the operation lever 36 also lowers the hopper 23 of the hopper introduction mechanism 20A, which is pressed by the adhesive member 62 and the stopper 80 and loop loops of the convergence mechanism at the bag opening 56 that is wide open. The front end portion 25a of the single-shaped piece whose ends are tapered by 82a is inserted. Thereafter, as described in the first embodiment, when a long packaged object is introduced from the cylinder 24 of the hopper 23, the packaged object falls along the inner circumferential surface of the hopper 23 by its own weight, and the hopper 23 The tip end portion 25a is enlarged and stored in the packaging bag 54.

As described above, according to the second embodiment of the present invention, since the lifting mechanism does not need a cam or the lower operation arm needs to be inclined, the structure becomes easier. And the adjustment member is moved to the inside of the support, and the stopper is attached to the backing material of the packaging bag in the holder so that the hopper end can be inserted more reliably and the packaged object can be guided. By employing tongues in the stress portion of vertical movement, the opening of the adhesive member after the adhesive is adhered to the package is also linked to the operation of the operation lever, so that opening can be performed slowly and the breakage of the sealing body can be eliminated.

10-12 show the packaging machine of 3rd embodiment of this invention, FIG. 10 is an external perspective view of the packaging machine of 3rd embodiment, FIG. 11 is a side view of the packaging machine of 3rd embodiment, FIG. It is operation explanatory drawing of the packaging machine of 10. This packaging machine 10B, like the packaging machines 10 and 10A, has a hopper introduction mechanism 20B having a bag inlet opening mechanism 60B and a hopper 23 inserted into the bag inlet opening opened by the bag inlet opening mechanism. ) And an operation mechanism 30B having an operation lever 36 for moving the hopper 23 up and down in conjunction with the sealing inlet opening mechanism 60B and the hopper introduction mechanism 20B. And the basic operation of each means is almost the same as the above-mentioned packing machine, each of the packing machine is packed in accordance with the length of the packaging bag to the guide member 26 and the guide member 26 to facilitate the vertical movement of the hopper 23 The structure of the point that the adjustment means 28 which adjusts the length of the hopper inserted in a bag is provided is different. Here, the description of the same parts will be omitted avoiding duplication, and other configurations and operations will be described.

10 and 12, a guide member 26 for smoothly moving the hopper 23 up and down and a support means 29 for supporting the guide member 26 are provided in the operation mechanism 30B. The guide member 26 is made of a substantially T-shaped rod-shaped body, and the upper portion of the T-shaped is fixed to the hopper support arm 27c. The hopper support arm 27c is connected to the connecting lever 35 through the horizontal rod of the guide member 26.

When installing the guide member 26 to the hopper support arm 27c and the connecting lever 35, the vertical rod portion (hereinafter referred to as a guide lever) received downward from the guide member 26, that is, the guide lever 27a Is held by the support means 29 so as to slide approximately parallel to the hopper 23 at a predetermined distance. By this holding | maintenance, the guide member 26 is moved up and down in association with the up-down movement of the operation lever 36, and the guide lever 27a and the hopper 23 also move up and down in synchronism, and at this time, The guide member 26 supports and guides the vertical movement of the hopper 23.

Support means (29) is a guide (27a) to be in for smoothly sliding the support, a plurality of guide rollers (29 ₁ ~29 _4), and these guide rollers (29 ₁ ~29 ₄₎ As shown in Fig. 11 It consists of a frame body 29 _{0 to be} installed.

Of guide rollers (29 ₁ ~29 ₄₎ plurality are secured to the frame body (29 ₀₎ to face up, insert the guide lever (27a) in between. Frame body (29 ₀₎ is fixed to the support plate via a holding (32a, 32b).

Therefore, by fixing the guide member 26 to the struts 32a and 32b by the support means 29, the installation of the guide member 26 is firm and the vertical movement of the guide member 26 is stabilized. As a result, the vertical movement of the hopper 23 can be stabilized, without the hopper support arm 27c shaking.

By arranging the guide member 26 in this manner, the vertical movement of the hopper is stabilized. However, in order to further stabilize, it is preferable to provide a member to be guided by contacting the hopper separately from the guide member.

It is an expanded perspective view which shows a hopper guide with a procedure mechanism.

This hopper guide 90 consists of the trough 91 'whose cross section is substantially semi-circular, and has a predetermined length, the diameter of which is slightly longer than the diameter of the hopper, and the hopper 23 in the trough 91'. It consists of a length that can move up and down smoothly. The back surface of the trough 91 'is fixed to the support 40. The lower end of the trough (91 ') is preferable to cut the bag because it is close to the inlet, it is out of the way the side wall (91 _1, 91 ₂₎ inserted into the hopper of the bag opening. Therefore, the up-and-down movement of the hopper becomes smoother by laying the hopper guide 90. This hopper guide 90 may be attached not only to the packaging machine 10B but to other packaging machines 10 and 10A.

In addition, the hopper support arm 27c is preferably fixed to the coupling lever 35 so that the hopper mounting portion at the front end thereof descends at a predetermined angle with respect to the point 3 _{1 of} the connecting lever 35.

By inclining the hopper support arm 27c, the hopper 23 and the guide member 26 attached to the tip of the support arm 27c are inclined to be received. At this time, the inclination of the guide member 26 changes the size of the guide rollers 29 _{1 to} 29 ₄ of the support means 29, and the like, for example, to reduce the size of the guide rollers 29 ₁ and 29 ₄ . Or by changing the installation location.

By inclining the hopper support arm 27c downward in this way and providing the hopper 23 at the tip of the support arm 27c, the tip of the hopper 23 approaches the support 32a when descending. Therefore, insertion of the hanging packaging bag into the bag opening becomes easy.

In the lower end of the guide lever 27a, a plurality of pin mounting holes 27 _{1 to} 27 ₃ are formed. The pin mounting holes (27 _{1-27 3)} is so fitted into the stop pin (27, ₀₎ having a predetermined length. The pin (27 _0), as a stopper to prevent escape from the frame body (29, ₀₎ when the guide lever (27a) has been lifted, and serves as a control mechanism for controlling the travel of the hopper 23. That is, small enough to move move the distance stop pin distance of the stop pin (27 ₀₎ hopper 23 to FIG lowest position of the 10 upward from (27 _3), for example, by moving the pin mounting holes (27 ₁₎ Lose.

Therefore, the stopper pin (27, ₀₎ by changing the installation position, the selection of the packaging bag tailored to the insert length adjustment and avoid packaging of the hopper 23 of the packaging pouch of this is possible.

Since also due to a change in the installation position of the stop pin (27, ₀₎ changes the moving distance of the hopper 23, the adjustment of the sealing inlet opening mechanism (60B) also it is required. This adjustment is performed by moving the position of the hinge cam 73 to the operation lever 61. That is, as to move downwardly the stop pin (27, ₀₎ from the location of the mounting holes (27 _1), and also moved to the bottom installation position of the hinge cam (73).

By changing the attachment position of this hinge cam 73, the rotating body 70 of the operating mechanism 30B abuts against the hinge cam 73 exactly, and it can contact smoothly.

Next, the operation | work encapsulating the packaged object to this packaging machine is demonstrated with reference to FIG. FIG. 12 is an explanatory view of the operation of the packaging machine shown in FIGS. 10 and 11. In the following description, reference numerals not given to FIG. 12 use those of FIGS. 10 and 11.

First, the operation lever 36 is pushed down like an arrow. When the operation lever 36 is pushed down, the other end of the operation lever 36 is lifted by rotating about the point, the connection lever 35 having one end connected to the other end is pushed up, and the connection lever ( The guide member 26 and the hopper support arm 27c to which the other end of 35 are connected are pushed up, and the hopper 23 raises. (See Figs. 12A and 12B).

When the operation lever 36 is pushed further down, the hopper 23 rises further together with the guide lever 27a, and the lower end of the hopper 23 rises upward from the bag opening of the packaging bag 53 provided on the support plate. At the same time, the tip is thinly bound by the loop ring 82a of the convergence mechanism 81 from the thin pieces 25 _{1 to} 25 ₁₀ of the hopper tip. Simultaneously with this, the rotary body 70 next to the operation lever 36 pushed down is engaged with the hinge cam 73 of the operation lever 61 to free the end of the operation lever 61 of the bag inlet opening mechanism 60B. Is moved in the direction of the strut 32a, and the adhesive member 62 provided at the free end thereof is pressed against the bag inlet of the packaging bag 53. (FIG. 12C). When the hinge cam 73 is pushed down by the hinge cam, for example, the hinge cam 73 remains undeformed even when engaged with the rotating body 70, and rotates about an axis when deployed. When the engagement with the rotating body 70 is released without disturbing the return of the rotating body 70, it returns to a circular shape.

Further pushing down the operation lever 36 raises the hopper 23 further, and when the rotating body 70 engaged with the hinge cam 73 of the operation lever 61 is out of the hinge cam 73, the operation lever ( 61 rotates about the axial point 61c and returns to an original position. The packaging bag in which the adhesive member 62 provided at the free end of the operating lever 61 is pressed down opens the bag inlet with the return of the operating lever 61. (FIG. 12 (d)). The stopper / adjustment member 70a restricts the operation of the hinge cam 73. By pushing down the operation lever 36 in this way, the front end of the hopper 23 is raised above the bag opening, and the bag opening of the packaging bag is opened. The operation lever 61 is stopped at a predetermined position by the adjustment member 70a and is maintained in the state where the sealing inlet is opened.

Subsequently, the operation lever 36 is raised upward this time as an arrow. As a result of the lifting, the guide lever 27a starts to descend, and according to the lowering, the tip portion (plural strip-shaped thin pieces 25 _{1 to} 25 ₁₀ ) of the hopper 23 is inserted into the bag inlet. At this time, as described above, the tip portion of the hopper is tied to the thread-like body 82 and the tip is tapered, so that the insertion into the bag inlet is smoothly performed. ((E) of FIG. 12).

In addition, when the operation lever 36 is lifted up, the tip portion of the hopper 23 enters the packaging bag, and the plurality of strip-shaped thin pieces 25 _{1 to} 25 ₁₀ of the narrowed tip portion are gradually enlarged and _opened .

In this state, a long packaged object is put from the cylinder 24 of the hopper 23. The packaged object then falls inside the hopper 23 by its own weight, enlarges and opens the tip of the hopper 23, and is stored in the packaging bag. ((E) of FIG. 12).

Thus, if the packaging bag containing the packaged object is pulled downward, for example, and pulled away from the holder (FIG. 12 (f)), the packaging bag 53 is peeled off from the adhesive member 62 while the upper edge portion is peeled off. It is broken from the sweat part and is removed from the holding tool.

In the packaging machine 10B, although the mechanism shown in FIG. 5 is used as the procedure mechanism 81, you may use another procedure mechanism.

14 and 15 show another procedure mechanism, FIG. 14 is a perspective view of a state where the hopper is inserted, showing another procedure mechanism, and FIG. 15 is an operation explanatory diagram when applied to the packaging machine 1OB. In addition, this procedure mechanism is applicable to the other packaging machines 10 and 10A.

The convergence mechanism (81A) and is guiding the vertical movement of the hopper 23, to control the binding annulus 93 'the thin pieces (25 _{1-25 10)} of the plurality of band-shaped, the movement of the annuli It consists of a spring body 96.

In addition, although the hopper guide 90 is not attached to the mechanism shown in FIG. 14, you may provide the hopper guide 90 similarly to 81 A of procedures. By providing the hopper guide, the vertical movement of the hopper becomes smoother.

The annular body 93 'has a diameter slightly larger than the diameter of the cylindrical body of the hopper 23, and consists of a cylindrical body which has a predetermined height, and the hopper 23 can move smoothly this cylindrical body. It is supposed to be.

The strut 32a connected to the outer circumferential wall of the annular body 93 'and the strut is fixed by the hinge 95. In addition, instead of the hinge, a paper member, for example, a bendable rubber body, may be used. Moreover, the annular body 93 'is not directly fixed to the support 32a, but is provided in the base of a separate member through the rotation means (for example, the hinge 95, etc.), and this support is supported. It may be attached to or detached freely. By such a detachable installation, exchange with other procedure mechanisms becomes possible.

The annular body 93 'is pulled by the spring body 96 so that the annular body 93' may be installed in the substantially vertical direction from the surface of the strut 32a via the hinge 95. As shown in FIG. That is, the spring force of the spring body 96 is adjusted and installed so that the hinge 95 may be substantially folded between the hinge installation part to the annular body 93 ', and the support | pillar 32a.

Therefore, before the hopper 23 is inserted into the annular body 93 ', the annular body 93' is installed upright from the support | pillar 32a, and when the hopper 23 is inserted into the annular body 93 ', a spring body ( 96 is extended and the annular body 93 'is maintained in the substantially horizontal direction. At this time, the annular body 93 'is pulled strongly by the spring body 96. As shown in FIG. In addition, when the hopper 23 rises, the annular body 93 'tries to return to an original state, ie, a standing state, by the tension force of the spring body 96. As shown in FIG.

This relationship is described below with reference to FIG. 15. It is operation explanatory drawing explaining the state which an annular body rotates by a spring body according to the up-down movement of a hopper.

When the packaging machine 10B is not in use, as shown in Fig. 15A, the hopper 23 is inserted into the annular body 93 ', and the annular body 93' is kept in a substantially horizontal state, and the spring body (96) is in an extended state. From this state, the hopper 23 when the lift so a plurality of thin pieces of the strip-shaped hopper (25 _{1-25 10)} reaches in the annular body (93 '), (b) in FIG. 15, (c) As shown, the annular body 93 'is pulled by the spring body 96 to converge the plurality of strip-shaped thin pieces 25 _{1 to} 25 ₁₀ , and the plurality of bands to be smaller than the size of the opening of the bag inlet. The tip of the thin pieces 25 _{1 to} 25 ₁₀ is converged. (See FIG. 15 (c)).

Thereafter, the hopper 23 is lowered, and when the tip of the hopper is inserted into the bag inlet of the packaging bag, the annular body 93 'is brought into contact with the outer circumferential surface of the hopper while being pulled by the spring body 96. It is returned to its original state. (See (d) and (e) of FIG. 15).

Annular body 93 'has a portion that faces the mounting section of the spring body 96, for further converging a plurality of thin pieces of the strip (25 _{1-25 10)} of the hopper 23, the guide tube (94 It is preferable to install). The guide cylinder 94 has a large diameter of the upper opening 94a and a smaller opening 94b, which has a wrapper shape, and extends in contact with a part of the side wall of the annular body 93 '. (93 ') a plurality of thin pieces of the strip (25 _{1-25 10)} of the hopper from the opening of the side wall of the procedure is to fit as.

According to the convergence mechanism 81A, the annular body can be made of a solid material, for example, plastic or metal, so that the durability is increased compared to the strip-shaped body of the convergence mechanism 81, so that replacement according to the frequency of use is unnecessary. . In addition, since the annular body has a predetermined height as compared with the string-shaped body, the hopper can be guided smoothly.

Fig. 16 shows yet another procedure mechanism and is a perspective view with the hopper inserted.

This convergence mechanism 81B uses an acyclic body in place of the annular body of the convergence mechanism 81A.

This acyclic body 101 has a converging portion formed of a substantially V-shaped converging piece, and is provided at one end of the frame 100 as shown in FIG.

The frame 100 has two long pieces 102 ₁ and 102 ₂ arranged in parallel, and the other end is connected by a piece frame 103. Of the V-shaped body bihwan (number sequel:收束片) (101) is formed of stretched out in a direction crossing each other from each end, the V-angle of the bottom of the two full-length frame (102 _1, 102 ₂₎ of the hopper A plurality of strip-shaped thin pieces are gradually converged and converged until they are smaller than the opening of the bag inlet. The width of the frame 100 is somewhat wider than the diameter of the hopper 23, and the rotation is freely held by the two short struts 104 ₁ and 104 ₂ so that the hopper can move up and down between the respective long frame. The V-shaped acyclic body (procedure piece) 101 and each of the long and short frame 102 ₁ , 102 ₂ , 103 are integrally formed of resin or the like.

An actuation bar 107 is attached to the guide member 26 at an approximately center position 108 of the actuation bar 107 in a direction orthogonal to the short side of the guide member 26. The length of the operation bar 107 to be longer than the width between the respective full-length frame (102 _1, 102 _2), the actuating bar 107 to each feature frame (102 _1, 102 ₂₎ when the hopper 23 increases Abuts and abuts, and pushes down the V-shaped convergence piece end (non-cyclic body part 101) downward.

In addition, the shape of a non-cyclic body is not limited to V shape, You may make another shape, for example, a curved shape. In addition, this acyclic body may be provided with a hook-shaped procedure piece in the long side frame 102 ₂ excluding the long side frame 102 ₁ and the short side frame 103 of the frame body described above.

This relationship is explained below with reference to FIG. It is a perspective view explaining the state in which an acyclic body rotates according to the up-down movement of a hopper.

Packaging machine (10B) is located between, as shown in unused city, state 17 (a), the hopper (23) each feature frame (102 _1, 102 ₂₎ of the frame body (100). When the hopper 23 rises from this state, each long mold frame 102 ₁ and 102 ₂ is pushed up by the hopper support arm via the operation bar 107, and the V-shaped procedure piece 101 moves downward. Pushed down. As the V-shaped procedure piece 101 is pushed down, the plurality of strip-shaped thin pieces 25 _{1 to} 25 ₁₀ of the hopper are converged between the V-shaped procedure pieces so as to be smaller than the size of the bag inlet opening. the front end of the thin piece (25 _{1-25 10)} of the plurality of band-shaped are converged. (See FIGS. 17B and 17C).

Thereafter, the hopper 23 is lowered, and the tip of the hopper 23 is inserted into the bag inlet of the packaging bag. (See FIGS. 17D and 17E).

According to this procedure mechanism 81B, since the non-circular body can be made of a solid material, for example, plastic or metal, the durability is increased, and replacement according to the frequency of use such as a real body is unnecessary. Moreover, since a non-circular body is provided in a frame and rocked by the up-down movement of an operation lever, the tip of a hopper can be efficiently converged efficiently, guiding the up-and-down movement of a hopper by a frame.

Fig. 18 shows a shooter placed on the packaging machine. In the case where the base stand 31 is a frame like the packing machine shown in FIG. 10, when the present packing machine is maintained at a predetermined height and the shooter 12 such as a slide stand is provided on the base stand 31, the bag is sealed in the upper packing machine. When the bag to be filled with the filling is removed from the holder and dropped as it is, the shooter 12 can recover and the work efficiency is improved. In addition, this shooter 120 is not installable only in the packaging machine of 3rd Embodiment of the said FIG. 10, and this shooter is similarly carried out by making the shape of a base stand frame also in the packaging machine of 1st, 2nd embodiment of this invention. Installation of 120 becomes possible.

Moreover, although the supporters 32 are all fixed to the base 31 by the packaging machines of the said, 1st-3rd embodiment, the height adjustment may be needed depending on a working place. It is a principal part perspective view which shows the adjustment mechanism of the height of a strut. This adjustment mechanism can be attached to the packaging machine of said 1st-3rd embodiment. The adjusting mechanism is respectively connected to a second holding (130a ₁ ~130b ₂₎ on the base board (31) to the fixed part of the respective holding (32a, 32b) has a structure fixed on the base board (31). Fixed to the base stand 31 of each of the secondary holding (130a ₁ ~130b ₂₎ is carried out by screwing. In addition, a plurality of pin mounting holes 132 _{1 to} 1132 ₆ are formed on the side surfaces in contact with the supports 32a and 32b so as to pass through the respective auxiliary supports 130a _{1 to} 130b ₁ . Height adjustment by inserting one of the pins fixed pin (131a, 131b) in the mounting hole (132 _{1-132 6)} to fix the holding (32a, 32b). Thereby, for example, workability can be improved by shortening the strut in case of sitting and working, or lengthening the strut in case of standing.

As can be used commonly for the above three embodiments, a more preferred embodiment of the procedure procedure described in FIG. 5 will be described with reference to FIG. 20. Fig. 20 shows another embodiment of the procedure procedure of the present invention, which is a schematic explanatory view, partly in cross section, showing a case where it is provided in the packaging machine of the third embodiment. However, it will be apparent to those skilled in the art that the same configuration can be provided in the first and second embodiments of the present invention.

The procedure of FIG. 20 differs from the procedure of FIG. 5 in that a second loop ring 82b is provided. The second loop ring 82b is fixed to a fastener 82c provided at one end of the guide lever 27a at a lower end thereof, and has a cylindrical connecting rod 84 installed to connect struts 32a and 32b at a predetermined height. After one rotation, the other end is connected to the weight 83. The second loop ring 82b provided in this manner is set to the same length as supporting the weight 83 instead of the first loop ring 82a when the hopper 23 is less than or equal to the predetermined height. ) Is lifted more than a predetermined height, the support is released. By providing such a second loop loop 82b, when the hopper 23 is located below, the convergence action by the first loop ring 82a prevents the hopper 23 from moving or inserts the packaged object. Even when the first loop ring 82a converges the thin pieces 25 _{1 to} 25 ₁₀ of the hopper 23, there is no possibility that the packaged object may be blocked inside the hopper 23, thereby providing better packaging of the article. I can do it.

As described above, the preferred embodiment of the sealing inlet opening mechanism is described with reference to FIG. 21 as an embodiment that can be adapted to any of the first to third embodiments. Fig. 21 is a perspective view of principal parts showing a more preferred embodiment of the bag inlet opening mechanism according to the present invention. The sealing inlet procedure mechanism shown in FIG. 21 is provided with a plurality of mounting holes 66 _{1 to} 6 _{4 4} which can be fixed by inserting the support shaft 65 near the upper end of the operation lever 61. This is because the places where the adhesive member 62 adheres are different depending on the packaging bag, such as a packaging bag provided at a position where the opening position is lower than a normal one, or a packaging bag provided with a seal portion for sealing the opening of the sealing body. Therefore, a plurality of mounting holes 66 _{1 to} 66 ₃ are provided so that the position of the adhesive member 62 can be appropriately changed by the packaging bag to be used. In this way, the mounting holes 66 _{1 to} 66 ₃ of the support shaft 65 can be changed in accordance with the height of the opening of the packaging bag, thereby enabling the position of the adhesive member 62 to be appropriately changed. Can be used for packaging bags.

As described above, the present invention ensures that a long packing machine, especially a long vegetable that is difficult to pack, such as asparagus, green onion, burdock or yam, can be reliably introduced into a flexible packing bag, for example, a plastic packing bag. Can be used for long packing machines.
