Description

The present invention relates to a horizontal rotary type automatic machine that divides a horizontally conveyed long packaging film (resin film) into a large number of bag portions and fills each bag portion in the horizontal direction with a content. The present invention relates to improved technology for filling and packaging machines.

Conventionally, using a long packaging film (resin film), the horizontal rotary type is one of the automatic filling and packaging machines that divide and package the contents such as powders that have been weighed into a number of packages. There is an automatic filling and packaging machine.

In this horizontal rotary automatic filling and packaging machine, for example, as described in Patent Literature 1 and Patent Literature 2, a packaging film or the like is horizontally wound from a film coil in which a packaging film or the like is wound around a core material. While pulling out and moving the film guide part, the packaging film is folded in half in a direction substantially perpendicular to the film traveling direction to form the bottom part of the bag part, and the packaging film is introduced to the turntable. do.

A large number of side seal bars arranged around the turntable move horizontally (rotational movement) by sandwiching the packaging film from the vertical direction while rotating at a speed synchronized with the introduced packaging film. A width seal (side seal: heat seal) extending perpendicular to the direction of travel is formed with respect to the packaging film to be applied.

Between the sequentially folded packaging films (upper opening bag portion), a plurality of side seal bars are arranged corresponding to the space between the side seal bars adjacent to each other, and are rotated synchronously with the packaging films and the side seal bars. A filling chute is inserted, and a predetermined amount of content (powder, granular material) is filled (thrown in) from this filling chute, then the filling chute is removed from the bag, and the resin film is sandwiched. remove the side seal bar.

The packaging film in which each bag portion is filled with contents in this manner is then top-sealed (heat-sealed) at the upper edge of the bag portion to be sealed. In this state, the width-sealed portion between the bag portions is cut or perforated along the longitudinal direction to obtain the required packaging form.

Japanese Patent Application Laid-Open No. 2003-341607 Japanese Patent Application Laid-Open No. 2006-124030

Here, in the conventional horizontal rotary type automatic filling and packaging machine as described above, a funnel-shaped bag is formed by sealing both sides of the film folded in two so that the upper side is open. When the lower end of the filling chute is inserted and the bag is filled with powder through the filling chute, the powder or the like dropped from the metering container to the filling chute adheres to the inner wall of the filling chute, There is a risk that the powder will adhere to this and form lumps of a predetermined size.

In such a case, there is a risk that the lump adhering to the inner wall of the filling chute will not be supplied into the bag portion, resulting in the production of a product with insufficient contents. Because it falls at a place where there is a risk of causing trouble with the mechanical part.

For this reason, in Patent Document 1, the filling chute is lowered into the bag portion of the upper opening and inserted to a predetermined position. An uneven groove (uneven surface 400) is formed on the sliding contact surface (80) of the cam (second cam 201) that vertically moves the filling chute so as to pull it out of the bag portion and the cam follower (79), and the filling chute is connected. A device has been proposed in which vibration is applied to the cam follower (79).

Recently, there are cases where tablets such as supplements are filled as contents, and in such cases, various types of supplements (with different effects, shapes, sizes, etc.) are combined as a group of tablets to be taken at one time. In such cases, the diameter of the funnel-shaped filling chute may differ depending on the timing and attitude of dropping large tablets from the metering container to the filling chute. There is a risk of clogging near the entrance to the narrowed portion (reduced diameter portion).

In the case of clogging due to the oversized tablets, there was a possibility that the clogging of the tablets could not be eliminated only by applying vibration to the extent that the accumulation of powder could be eliminated as in Patent Document 2.

Here, by increasing the width and depth of the concave-convex groove (convex-convex surface 400) formed on the sliding contact surface (80) of the copying cam (second cam 201), it is also assumed to increase the vibration given to the filling chute. However, since the copying cam (second cam 201) is attached to the base of the main body of the horizontal rotary automatic filling and packaging machine, it cannot be easily replaced. It is very difficult to replace in advance.

For this reason, it is difficult to adjust the amount of vibration of the filling chute when changing the type of contents to be packed (powder, tablet, etc.) according to customer needs. If the amount of vibration in the vertical direction of the filling chute increases, the abrasion of each contact part increases, packaging defects (defects such as wrinkles in the sealing part) occur, noise and vibration increase, and tablets are damaged. If the content is changed to powder or the like while the copying cam is still capable of applying vibrations, excessive vibrations will occur, which is undesirable for the user.

For this reason, it is desirable to be able to easily adjust the amount of vibration applied to the filling chute according to the contents to be filled.

In addition, it is conceivable to apply a shock such as a blow to the filling chute, but the stress on the filling chute and the packaging film is large, and parts breakage and packaging defects (defects such as wrinkles at the seal part) may occur, and vibrations may occur.・The noise increased, which was undesirable for the user.

Therefore, it is desirable to be able to easily adjust the amount of vibration applied to the filling chute in a relatively quiet and reliable manner.

An embodiment according to the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the present invention is not limited by the embodiments described below.

First, with reference to FIG. 1, the overall configuration of a horizontal rotary automatic filling and packaging machine according to the present invention will be described.
FIG. 1 is a front view (partial cross-sectional view) showing a horizontal rotary automatic filling and packaging machine according to the present invention. As shown in FIG. 1, a horizontal rotary automatic filling and packaging machine 1 includes a packaging film original fabric roll support shaft 2, a packaging film feeding device 3, a packaging film folding guide 4, a turntable 21, a side seal device (side seal bar) 5, a filling chute 6, a content storage hopper 7, a mass weighing rotary disk device 8 which is a weighing device, a top seal device (top seal roll) 8, a cutter device 10, an unloading slide table 11, and a control device 12.

The packaging film is wound into a roll as a packaging film original fabric roll F1 and attached to the packaging film original fabric roll support shaft 2 .
Here, the packaging film is composed of a transparent or translucent material, for example, composed of a base film such as PET and a heat seal film such as polyethylene having a lower melting point than the base film. Moreover, the packaging film F1 may have a three-layer structure of a base film, an intermediate film, and a heat seal film.

The packaging film F2 pulled out from the original packaging film roll F1 supported by the original packaging film roll support shaft 2 passes through the packaging film feeding device 3, and then flows continuously rightward in FIG. The packaging material film folding guide 4 folds the film in two along the central portion in the longitudinal direction to form a U-shape with an open top. The folded packaging film F3 is introduced into the turntable 21 from the tangential direction (A1 direction) of the turntable 21 as shown in FIGS. (A2 direction).

On the turntable 21, as shown in FIG. 2A, a large number of side seal devices (side seal bars) 5 forming a width seal are arranged concentrically. The side seal device 5, which rotates at a speed synchronized with the turntable 21, is positioned at a predetermined position (peripheral direction and height) with respect to the packaging film F4 introduced into the turntable 21 and rotated in the circumferential direction (direction A2). direction positioning), and at the same time, the packaging film F4 is heat-sealed in the width direction and locally heat-pressed.

At this time, the portion of the packaging film sandwiched by the side sealing devices 5 is melted by the heat supplied from the side sealing devices 5 . At the same time, since the side seal device 5 sandwiches the packaging film F4, the melted portion of the folded packaging film F4 is pressurized. As a result, the heat seal films of the double-folded packaging film F4 are crimped to form side seals F71 and F72 (see FIG. 2(B)). In this manner, a plurality of bag portions F75 (see FIG. 2(B)) sandwiched by the side seal devices 5 are formed in the double-folded packaging film F4.

In parallel with the heat-sealing operation of the side sealing device, the filling chute 6 is inserted between the folded packaging film F4, and the contents weighed by the mass weighing rotary plate device 8 pass through the filling chute 6. inserted through. A plurality of filling chutes 6 concentrically arranged on the turntable 21 are configured to rotate in the circumferential direction (direction A2) at a speed synchronized with the turntable 21 and the packaging film F4.

Thereafter, the packaging film F5 filled with contents is sent out from the turntable 21 in the tangential direction (A3 direction), and the top seal device (top seal roll) 9 seals the bag portion F75 of the packaging film F5 (Fig. 2 ( A top seal F74 (see FIG. 2(B)) is formed by heat-sealing and thermo-compression bonding to the filling port (upper open) of B)). As a result, the top-open packaging film (continuous packaging bag) F5 filled with the content becomes a continuous packaging bag F6 in which the content F76 (see FIG. 2B) is sealed.

After that, the width seal formed by the cutter device 10 is cut near the center to produce an individual packaging bag F7 (FIG. 2(B)). It should be noted that it is also possible to produce a package body by separating a plurality of packaging bags F7 in a continuous state, instead of individually.

FIG. 3A is an enlarged view of the side sealing device 5, the filling chute 6, the packaging film F4, etc., which are rotated synchronously with the turntable 21 in the horizontal rotary automatic filling and packaging machine 1 according to the present invention.

As shown in FIG. 3(A), the packaging film F4, which is folded in two along the central portion in the longitudinal direction to form a U-shape with an upper opening, is attached to the sides of the side sealing devices 5 arranged at predetermined intervals. The sides are sealed by being sandwiched between the seal bars 51, 52 and the side seal bars 53, 54 in the minor axis direction. 2 (B)), the filling chute 6 is inserted from the upper opening. Reference numerals 51 and 52 denote opening/closing side seal bars (movable side), and reference numerals 52 and 54 denote receiving side side seal bars (fixed side).

The side seal bars 51 and 52 and the side seal bars 53 and 54 of the side seal device 5 are arranged when the packaging film F4 is transported from the tangential direction (A1 direction) and when the packaging film F5 is transported in the tangential direction (A3 direction). When unloading, it is retracted downward in FIG. 1 so as not to interfere with the packaging film, etc., and after the packaging film F4 is moved in the circumferential direction (direction A2), it moves upward from the bottom in FIG. is set to a predetermined height, and is operated to sandwich the packaging film F4 at that position. It can be configured to do so by a profiling cam (not shown).
Here, the turntable 21 and the copying cam constitute a part of the side seal device driving mechanism according to the present invention.

The filling chute 6 supported by the chute arm 63 is rotated together with the turntable 21. When the packaging film F4 is transported from the tangential direction (A1 direction) and when the packaging film F5 is transported from the tangential direction (A3 direction), it is retracted upward in FIG. 1 so as not to interfere with the packaging film, and after the packaging film F4 is moved in the circumferential direction (A2 direction), It is moved downward, and its tip portion (content discharge port) 62 is inserted into the bag portion F75 from the upper opening. It is configured to be formed by the formed profiling cam 100 .
Here, the turntable 21 and the copying cam 100 constitute a part of the filling chute driving mechanism according to the present invention.

As shown in FIG. 4, the profiling cam 100 is supported by the body frame 6 coaxially with the rotary shaft 21A of the turntable 21, and its shape is centered around the rotary shaft 21A, as shown in FIG. It has a substantially annular shape.

The upper surface of the copying cam 100 functions as a sliding contact surface 101 that makes sliding contact with the cam follower 65, and as shown in FIG. The cam follower 65 and thus the filling chute 6 can be moved up and down in a predetermined manner in order to insert and withdraw the leading end portion (discharge port for the contents) 62 from the upper opening of the packaging film F4 into and out of the bag portion F75. It is configured with a cam shape (profile).

The cam follower 65 is rotatably supported by a vertical movement shaft (rod) 64 , and the chute arm 63 and the filling chute 6 are supported by the vertical movement shaft 64 .

Here, in this embodiment, as shown in FIG. 5 and the like, the cam follower 65, the vertical movement shaft 64, and the filling chute 6 are provided with an uneven surface 200 for giving vertical vibration.

The uneven surface 200 vertically vibrates (vibrates) the vertically movable shaft 64 that rotates together with the turntable 21 .

In the present embodiment, the width and depth of the uneven surface (uneven groove) 200 (that is, the period and amplitude of vibration applied to the filling chute 6, that is, the amount of vibration) are determined by the inner surface of the filling chute 6, for example. It can be set to a size that can suppress adhesion and deposition of contents (powder) to the tablet (or a size that is sufficient to give vibration that can suppress tablet clogging).

Here, in the present embodiment, the uneven surface 200 is formed on an uneven metal fitting (uneven block) 210, and as shown in FIG. ing.

That is, according to the present embodiment, when the type of contents to be bagged (powder, granules, tablets, etc.) is changed according to customer needs, it is possible to apply a desired vibration. By replacing with the fitting 210, the amount of vibration of the filling chute can be easily adjusted (changed) according to customer needs.

As a result, the amount of vibration in the vertical direction of the filling chute cannot be adjusted, and compared to the conventional case where the amount of vibration is always large, wear of each contact part increases and packaging defects (such as wrinkles in the seal part) occur. ) can be reliably suppressed, and noise and vibration can be suppressed to a low level.

That is, according to the present embodiment, the concavo-convex metal fitting 210 and thus the concavo-convex surface 200 can be easily replaced according to the type of contents to be bagged (powder, granules, tablets, etc.). Therefore, if the content (powder) adheres to the inner surface of the filling chute 6, by replacing the concave-convex metal fitting 210 in advance according to the type of content to be bagged (powder, granules, tablets, etc.) (or when the filling chute 6 is clogged with tablets), the tablets can be dropped without fail.
Although it is difficult to remove and replace the entire substantially annular profiling cam 100 from the horizontal rotary automatic filling and packaging machine 1, only the uneven metal fitting 210 having the uneven surface 200 can can be partially detached and replaced from the outside of the horizontal rotary automatic filling and packaging machine 1 relatively easily.

The uneven surface 200 can be formed on a part of the sliding contact surface 101 of the profiling cam 100 with the cam follower 65. The front end (discharge port) 62 can be formed in at least part of the rotational movement range in which it is inserted into the packaging film bag portion F75.

Since the concave-convex fitting 210 and thus the concave-convex surface 200 are configured to be easily replaceable, the width and depth of the concave-convex surface (convex groove) 200 (that is, the period and amplitude of the vibration applied to the filling chute 6) size) can be easily changed, it is possible to provide vibrations that meet customer needs.

The specifications (shape, size, number) of the uneven surface (uneven groove) 200 can be appropriately adopted according to the purpose and effect, as shown in FIGS. 7(A) to 7(F).

The specifications of the uneven surface (uneven groove) 200 shown in FIG. 7(A) have a groove width (the length of the bottom portion of the groove) expanded on the basis of the example shown in FIG. 6(B). As a result, the frequency of vibration is reduced, and the vibration (amplitude) imparted to the cam follower can be increased.

Further, the specifications shown in FIG. 7(B) are shapes in which the groove depth is increased based on the example shown in FIG. 6(B). Thereby, the vibration (amplitude) applied to the cam follower can be increased.

Moreover, the specification shown in FIG. 7(C) is a shape in which the convex top surface is arcuate. As a result, the impact on each protrusion can be reduced, which can contribute to the suppression of packaging defects (defects such as wrinkles in the seal portion) due to vibration, and the reduction of wear, noise, and the like.

Further, the specifications shown in FIG. 7(D) have a shape in which the unevenness is wavy. As a result, the filling chute 6 can be vibrated up and down with almost no impact, which contributes to suppression of packaging defects (defects such as wrinkling of the sealing portion) due to vibration, and reduction of wear and noise.

The specifications shown in FIG. 7E are shapes in which the size of the unevenness differs depending on the position (a combination of unevennesses with different specifications). As a result, it can be adopted when it is desired to gradually increase or decrease the strength of the vibration.

It is also possible to replace the chute with a smooth shape (normal shape) as shown in FIG. 7(F). This contributes to the suppression of packaging defects due to vibration (defects such as wrinkles at the seal), as well as the reduction of wear and noise.

Thus, according to the present embodiment, since the uneven surface 200 can be easily replaced, the type of contents to be packed (powder, granules, tablets, etc.) can be changed according to customer needs. In this case, the amount of vibration of the filling chute can be easily adjusted according to customer needs. As a result, the amount of vibration in the vertical direction of the filling chute cannot be adjusted, and compared to the conventional case where the amount of vibration is always large, wear of each contact part increases and packaging defects (such as wrinkles in the seal part) occur. ) can be reliably suppressed, and noise and vibration can be suppressed to a low level.

Further, in the above, the case where the concave-convex metal fitting 210 is configured by a block-shaped (lump-shaped) member is exemplified, but it is not limited to this. As shown in (A) and FIG. 9(B), an uneven plate-shaped member (uneven plate) 310 is adopted by bending a plate-shaped member into an L shape, and the tip thereof is shaped like a comb. It is also possible to make the portion of .function.

10(A) to 10(C) exemplify a specification change example of the uneven plate member 310 having the uneven surface 300. FIG.

FIG. 10A is a cross-sectional view of a concave-convex plate (convex-convex plate-like member 310) with a reference thickness (for example, 1 mm), and FIG. FIG. 10C is a cross-sectional view of a plate (uneven plate-like member 310), and FIG. 10C is a cross-sectional view of an uneven plate (uneven plate-like member 310) having a thickness (eg, 2 mm) greater than the reference thickness.

As described above, according to the concave-convex plate member 310 according to the present embodiment, replacement or retrofitting (new installation) is possible relatively easily. Since (amount of vibration) (vibration period, amplitude) can be changed, a desired amount of vibration can be easily obtained according to the degree of clogging of the filling chute 6, and the powder adheres to the inner wall of the filling chute 6. In addition to dropping the clumps formed by this process, even if clogging occurs due to a large tablet, the clogging can be eliminated.

As described above, according to the present embodiment, the type of contents to be bagged (powder, tablet, etc.) can be changed by the customer, compared to the conventional case where the entire copying cam 100 has to be replaced. Since the amount of vibration can be easily adjusted (changed) according to the needs of the customer, it is possible to provide a more user-friendly horizontal rotor type automatic filling and packaging machine.

In other words, according to the present embodiment, a horizontal rotary automatic filling and packaging machine that can control vibration and noise and apply adjustable vibration to the filling chute while having a relatively simple and low-cost configuration is provided. can provide.

Here, an experiment was conducted to confirm the effect of imparting vibration to the cam follower 65 by changing the size (groove width L, groove depth H) of the uneven surface 200 (300) according to the present embodiment. is shown in FIG.

That is, FIG. 11 shows the case where the groove width (groove width in the direction in which the cam follower advances) L mm and the groove depth H mm of the uneven surface (groove) are changed with respect to the outer diameter φD (here, φ28 mm) of the cam follower 65. It is a figure which shows the confirmation experiment result of a vibration provision effect.

From the results shown in (IV) of FIG. 11, L / D (x 100) = 18% (≈ 17.9%) or more, preferably L / D (x 100) = 29% (≈ 28.6 %), it has been found that the cam follower and thus the filling chute can be well vibrated.

Also, if L/D (×100)=29% (≈28.6%) or more, even if the groove is relatively shallow (groove depth H=0.5 mm or more), the cam follower extension is good. It was also found that vibration can be imparted to the filling chute.

Various modifications can be made without departing from the gist of the present invention.
