DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding and filling apparatus for filling a rectangular tube-shaped container material with contents such as liquid and sealing the top of the container. In particular, the present invention relates to a container rotating device that rotates the direction of the conveyed container material by 90 ° or an integral multiple thereof, which is an apparatus constituting the molding and filling device.

[0002]

2. Description of the Related Art It is already known that there are so-called goebel top type containers and flat top type containers as paper containers containing contents such as liquids. The goebel top type container is a container in which the container top P is folded in a triangular cross section as shown in FIG. On the other hand, a flat-top type container is a container in which the container top P is folded into a planar shape as shown in FIG.

[0003] Flat top type container (Fig. 15)
Is generally formed from a flat cylindrical container material 1 having openings at both ends P and Q as shown in FIG. The formation process is briefly described as follows. In addition, the container bottom is formed in the first end opening Q thereafter, while
Since a container top is formed at the second end opening P, the first end Q may be referred to as a container bottom and the second end P may be referred to as a container top in the following description.

[0004] First, a flat container material 1 is spread out to form a rectangular cylindrical container material 2 (FIG. 11). Next, the first end Q of the container material 2 is folded to form a container bottom as shown in FIG. Next, the second end opening P is pushed in from the direction of arrow B, and the top pieces a and b are folded inside. Then, as shown in FIG. 13, the top pieces a and b of the container material are folded inside the container, while the other top pieces c and d located between the top pieces a and b are moved outside the container. Protrude. These protrusions are commonly referred to as ears. By the folding process shown in FIG. 13, the bonding region e on the top of the container material is bonded.

After the bonding area e is bonded, the bonding area e is folded as shown by the arrow C, and the entire top P of the container is pressed from above, so that the top P of the container material is flat as shown in FIG. Molded into a shape. Next, the ears c and d protruding to the outside of the container material are folded toward the side wall surface of the container material as shown by an arrow D. Further, as shown in FIG. It is fixed to the side wall surface of the container material by heat welding. Thereby, the intended flat-top type container is formed.

A feature of the manufacturing process of the flat top type container is that ears c and d (FIGS. 13 and 14) are formed to protrude outside the side wall surface of the container material. On the other hand, in the manufacturing process of the gobel top type container shown in FIG. 16, since each part of the container top is folded inward, the outer side of the side wall surface of the container material like the ears c and d. There are no projecting parts.

A molding and filling apparatus for producing a goebel top type container is disclosed in Japanese Patent Publication No. 48-5 / 1976.
No. 712 discloses this. In this device,
A plurality of container materials are intermittently transported in a lined state, and during the transport, various processes such as a process of filling the container material with contents and a process of sealing the top of the container material are performed. In this case, since there is no portion that protrudes to the outside of the container material such as the ears c and d in the gobel top type container, the plurality of container materials to be conveyed are arranged close to each other.

On the other hand, Japanese Patent Application Laid-Open No. 56-411 discloses a molding and filling apparatus for producing flat-top type containers.
No. 07 is disclosed. In this apparatus, as in the case of the above-mentioned Goebel top type container forming and filling apparatus, a plurality of container materials are conveyed in a state of being arranged side by side, and each processing such as filling processing of contents and sealing processing of the container top is performed. Receive. However, in a flat top type container, as shown in FIG. 13 or FIG.
Ears c and d project outside the side wall surface of the container material,
In a usual molding and filling apparatus, the lugs c and d protrude along the conveying direction of the container material.
For this reason, a large space must be provided between the two container materials conveyed adjacent to each other so that the protruding ears c and d do not collide with each other.
As described above, since a large space had to be provided between the container materials to be conveyed, the conventional flat-top type container forming and filling apparatus has a long overall length and a large installation space. There was a problem of taking.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems particularly in a flat-top type container forming and filling apparatus. Shorten the length,
It is an object of the present invention to be able to install the molding and filling device even in a narrow installation space.

[0010]

A container rotating device according to the present invention comprises a container bottom forming means for forming a container bottom at a first end of a rectangular cylindrical container material, and a second container material having a bottom formed thereon.
Content filling means for filling the content through the end opening, container top sealing means for sealing the second end opening of the container material filled with the content, container bottom forming means, content filling means,
And it is used for a molding and filling apparatus having a container conveying means for conveying the container material between the container top sealing means.

The container rotating device is arranged between the container bottom forming means and the contents filling means, and is capable of transferring the container material having the container bottom formed thereon, which is conveyed by the container conveying means, by an integral multiple of 90 °. Rotate. The container rotating device includes a container lifting means for lifting the container material conveyed by the container conveying means from the container conveyance path, a rotating member into which the container material to be lifted is fitted, and rotating the rotating member by an integral multiple of 90 °. And a container lowering means for lowering the container material inserted in the rotating member to the container conveying path.

[0012]

The container material whose bottom is formed by the container bottom forming means is conveyed on the container material conveying means. The conveyed container material is subjected to content filling processing by the content filling means, and further, sealing processing of the top opening is performed by the container top sealing means. In this container top sealing process, the ears c and d (FIGS. 13 and 14) are formed so as to protrude outside the side wall surface of the container material.

However, before the container material is conveyed to the container top sealing means, the container material is rotated by an integral multiple of 90 ° by the container rotating device. Oriented at right angles to it. As a result, there is no projecting portion in the transport direction of the container material. Therefore, there is no problem even if the interval between the container materials adjacent in the transport direction F is reduced. The fact that the distance between the conveyed container materials can be reduced means that the overall length of the molding and filling apparatus can be reduced. Also,
When the container material is rotated by 90 ° or an integer multiple thereof, the container material is lifted from the container transport path and fitted into the rotating member. By rotating the rotating member by 90 ° or an integer multiple thereof, the container material is rotated by 90 ° or an integer multiple thereof.

[0014]

That is, a rotary conveyor 16 in which the mandrels 15 are radially arranged is provided. The rotary transporter 16 is driven by a drive source (not shown) and intermittently rotates by １ ／ rotation about the central axis L. A well-known container bottom forming mechanism (not shown) is provided around the rotary conveyor 16.

The contents filling device 6 shown in FIG. 6 has a liquid tank 27 containing contents, for example, liquid, and a cylindrical filling nozzle 29 connected to a connection pipe 28 extending from the liquid tank 27. ing.

The container top sealing device 7 provided in the left region of the forming and filling device includes a top heater 17 for heating the top of the container material, a top breaker 18 for temporarily folding the top of the container material, and a top for the container material. Press 19, which presses the container downward, an ear press 20 which gives a fold to the ear of the top of the container projecting outside the side wall surface of the container material, and a press of the container material conveyed by the conveyance chains 4a, 4b. An adhesive applying device 22 having an adhesive spray nozzle 21 disposed at both sides is provided, and an ear fixing device 23 for pressing and fixing the ear at the top of the container against the side wall surface of the container material. .

The ear fixing device 23 is, as shown in FIG.

As shown in FIG. 5, the drive chain 25 is driven by auxiliary sprockets 27a and 27b that are coaxial with the container transport sprockets 13a and 13b, and moves in synchronization with the container transport chains 4a and 4b. Has become.

Hereinafter, the operation of the molding and filling apparatus having the above configuration will be described.

First, a flat container material 1 as shown in FIG. 10 is placed in a material stacker 30 (FIG. 5, FIG.
FIG. 6) shows a stacked state. Then, as shown in FIG. 7, the lowest one of the stacked container materials 1 is extracted from the stacker 30. At this time, the container material 1 is spread out into a rectangular tube shape (FIG. 11). In FIG. 1, a container material 2 spread in a rectangular cylindrical shape is inserted into one mandrel 15 of a rotary transfer device 16 and is intermittently conveyed as the mandrel 15 rotates. During this rotation conveyance, a container bottom is formed at the first end Q (FIG. 12) of the container material 2 by a container bottom forming mechanism (not shown) disposed around the mandrel 15.

The container material 2a with the bottom formed is transported to a position E where the mandrel 15 faces vertically downward, and is removed from the mandrel 15 at that position. The removed container material 2a is placed at the right end of a straight container transport path formed between the transport chains 4a and 4b in FIG.
Transport chains 4a and 4b receiving container material 2a
Then, the container material 2a is transported linearly and intermittently in the leftward direction in FIG. 6, that is, in the direction of arrow F in FIG. Note that the ear crests c and d (FIG. 12) of the container material 2a received by the transport chains 4a and 4b face the transport direction F.

The container material 2a conveyed by the conveying chains 4a and 4b is first sent to a direction changing stage G provided with a container rotating device 5 (FIG. 6). In this direction changing stage G, the container material 2a is once lifted from the container conveying path, rotated by 90 ° as indicated by an arrow H, and then lowered again to the container conveying path. By this processing, the ear crests c and d of the container material 2a are oriented in a direction perpendicular to the container transport direction F. This container rotation processing will be described later in detail.

The changed container material 2a is then
It is transported to a position below the filling nozzle 29 of the content filling device 6 and stops there. The filling nozzle 29 is connected to the liquid tank 27
The liquid inside the container material is discharged to the outside by a fixed amount, and the discharged liquid is filled, that is, injected into the container material 2a through the top opening P (FIG. 12) of the container material 2a. The container material 2a filled with the contents is then conveyed to the top heater 17, where the top, particularly the bonding area e (FIG. 12), is heated. This heating imparts tackiness to the bonding area e.

Thereafter, the container material 2a is transported to the top breaker 18. The top breaker 18 presses the top pieces a and b located next to the container ear top pieces c and d from the side to the inside as shown by the arrow B in FIG. By this pressing process, the top P of the container material 2a is temporarily folded. At the time of this temporary folding, the ear crests c and d project outward as indicated by the arrow J. After the temporary folding process, the container material 2
a is carried to the top press 19. This top press 1
9 presses the adhesive region e at the top of the container material from both sides, as shown by the arrow K in FIG. 13, and adheres the adhesive regions e, which have already been provided with tackiness, to each other based on the tackiness.

The container material 2a to which the bonding region e is bonded is
Then, it is sent to the ear press 20. This ear press 2
0 pushes the bonding area e so as to be flat as shown by the arrow C in FIG. By this pressing, the container top P is formed into a flat shape as shown in FIG. Thereafter, the container material 2a is transported to an adhesive application stage in which two adhesive spray nozzles 21 are provided. These two adhesive injection nozzles 21 are used to transfer the container material 2a
An adhesive is sprayed on the upper outer peripheral surfaces of the two opposing side walls.

The container material 2a to which the adhesive has been sprayed is
In FIG. 7, it passes between two opposing guide plates 24. At this time, the top ear pieces c and d of the container material 2a are:
While being guided by the guide plate 24, an arrow D shown in FIG.
Is bent toward the container side wall surface f as shown by. After that, the container material 2a is fed between the two opposing chains 25 having the ear pressing pieces 26.
The distance between the adjacent ear pressing pieces 26 attached to the individual chains 25 is set to exactly match the distance between the two container materials 2a to be conveyed.

Therefore, the top ears c and d of the container material 2a fed between the chains 25, 25 are pressed by the ear pressing pieces 26 to the side wall surface of the container material 2a where the adhesive is applied. Pressed to. In this case, the movement of the chain 25 that conveys the ear pressing piece 26 and the container material 2a
Since the movements of the transport chains 4a and 4b for transporting the same are synchronized with each other, the ear pressing pieces 26 do not move relative to the container material 2a but continue to push the fixed positions of the ears c and d for a long time. Due to this long pressing process, FIG.
As shown in FIG. 5, the ears c and d at the top of the container are securely fixed to the side wall surface f of the container by an adhesive, and a flat-top type liquid container as a product is completed.

When the flat-top type product container reaches the consumer's hand and takes out the liquid inside the container, one or both of the ears c and d are broken up and lifted upward. The tip of the part is cut using a cutting instrument such as scissors to form an opening, and the liquid is poured out through the opening.

As described above, in the present molding and filling apparatus, the direction of the container material 2a having the bottom portion is changed by 90 ° before the filling of the contents by the filling nozzle 29. Due to this direction change, the ears c and d at the top of the container material are oriented at right angles to the transport direction F of the container material.

Assuming that the container material 2a is not so changed in direction, the ears c and d remain in the transport direction F. The ears c and b are moved from the temporary folding process of the top by the top breaker 18 to the ear press 20.
By receiving the top processing up to the top pressing processing by the above, it projects outside the container side wall surface. Therefore, in a case where the container material 2a is transported in a state where the ears c and d face the transport direction F, the ears c and d of the adjacent container material 2a are prevented from hitting each other. For this reason, the distance between the container materials 2a must be considerably widened. However, if the distance between the container materials is set to be large as described above, the length of the molding and filling apparatus becomes extremely long, and the installation space must be increased.

On the other hand, according to the above-described apparatus in which the direction of the container material 2a is changed by 90 °, the interval between the container materials can be reduced, so that the entire length of the molding and filling apparatus does not increase. .

Hereinafter, a specific structure for changing the direction of the container material 2a will be described in detail with reference to an example.

(Container Rotating Apparatus) FIG.
1 shows an embodiment. In this figure, the container material 2a having the bottom portion already formed is intermittently transported in the direction of arrow F. Reference numeral 31 denotes a rail for supporting the container material 2a from below. Inside the machine frame 10, the drive shaft 1
The lift cam 32 fixed on the upper part 1 is fixed,
A lift cam lever 33 is disposed below the cam. The lift cam lever 33 has one end 33a.
Is rotatably supported by a frame 35 integral with the machine frame 10 and is urged upward by an air cylinder 34. Due to the urging force, the roller 36 integral with the cam lever 33 contacts the outer peripheral surface of the cam 32 under pressure.

An elevating member 38 is connected to the other end 33b of the cam lever 33 via a universal joint 37. On the elevating member 38, two elevating rods 39a and 39b are fixed. Each of these lifting rods extends upward and is supported by slide bushes 40, 40 fixed to the machine frame 10. As shown in FIG. 2, the upper end of one lifting rod 39a extends to the vicinity of the bottom surface of the container material 2a transported by the transport chains 4a and 4b. The upper end of the other lifting rod 39b extends to a position higher than the upper end of the conveyed container material 2a.

In FIG. 2, a long lifting rod 39 is used.
A bracket 41 is fixed to the upper end of b, and a pressing claw 42 is fixed to the tip of the bracket 41. As shown in FIG. 4, the holding claw 42 extends over one side wall of the container material 2a.

In FIG. 2, when the drive shaft 11 rotates, the lift cam 32 also rotates, and the lift lever 33 follows the rotation of the lift cam 32 about the shaft end 33a as indicated by an arrow MM '. When the lift lever 33 swings, the elevating member 38 connected to the lever end 33b moves up and down, and the elevating rods 39a and 39b move up and down accordingly.

When the lifting rods 39a and 39b are at the lowest position, the upper end of the lifting rod 39a is located immediately below the bottom surface of the conveyed container material 2a, and is fixed to the upper end of the other lifting rod 39b. The holding claw 42 is located just above the upper end of the conveyed container material 2a. When both rods 39a and 39b are raised to the uppermost position, the upper end of the lifting rod 39a is raised to the position shown by the dashed line N, and the holding claw 42 is raised to the position shown by the dashed line R.

In FIG. 1, two rotating plates 4 made of flat plates are provided above the conveyed container material 2a.
4, 44 are provided. As shown in FIG. 3, these rotating plates 44 are provided with a top plate 46 supported by columns 45.
Are supported rotatably about the axes L1 and L2, respectively, but immovable in the axial direction. A shaft 44a integral with each rotary plate 44 penetrates the bearing 47 and protrudes upward, and links 48, 48 are connected to the protruding ends thereof. These links 48 are driven by a drive link 49 and swing together. The drive link 49 is connected to an elevating rod 51 via an L-shaped lever 50, and the elevating rod 51 is connected to one end 52b of a container rotating lever 52 rotatably supported by the frame 35. The roller 53 provided at the center of the container rotation lever 52 is in contact with the outer peripheral surface of the container rotation cam 55 under pressure by the spring force of a tension spring 54 provided between the machine frame 10 and the lever 52. . The container rotation cam 55 is similar to the lift cam 32 shown in FIG.
1 fixed on.

When the container rotation cam 55 rotates in response to the rotation of the drive shaft 11, the lever 52 swings and the lifting rod 51 moves up and down. Lifting rod 5
1 is moved up and down via the L-shaped lever 50.
9, the drive link 49 linearly reciprocates. Then, the linear movement of the drive link 49 causes the link 48,
The rotation is transmitted to the rotating plate 44 via 48, and the rotating plate 44 rotates as shown by the arrow. In this case, as shown in FIG. 4, the rotating plate 44 reciprocates between a solid line position and a chain line position, that is, in an angle range of 90 °.

As shown in FIG. 2, the air cylinder 5 is attached to the lower ends of two columns 56, 56 hanging from the lower surface of the top plate 46.
7, 57 are fixed. Then, as shown in FIG. 4, two guide blocks 58 are fixed to the ends of the output rods of these air cylinders 57, respectively. These guide blocks 58 are provided with air cylinders 57.
To reciprocate between a retracted position shown by a solid line and a protruding position shown by a chain line.

Hereinafter, the operation of the container rotating device having the above configuration will be described.

In FIG. 1, when the container material 2a conveyed in the direction of arrow F reaches a position below the rotary plate 44, the conveyance of the container material 2a is temporarily stopped. Container material 2a
Is transported, the lifting rod 39a is lowered to the lowest position so as not to hinder the advance of the container material 2a. When the container material 2a stops at a position below the rotary plate 44, the lifting cam lever 33 swings to raise and lower the lifting rods 39a and 39b. In particular, the container material 2a is lifted upward by the shorter lifting lever 39a. .

The container material 2a thus lifted moves upward while covering the rotating plate 44. At this time, as shown in FIG. 4, the rotating plate 44 is positioned diagonally to the container material 2a, and
Guide the two corners. In addition, when the flat container material 1 as shown in FIG. 10 is spread out into the rectangular cylindrical container material 2 as shown in FIG. 11, the cross-sectional shape of the container material 2 does not become an accurate square shape, Due to the elastic restoring force of the material, a parallelogram is always formed. The tendency of the cross-sectional shape of the container material 2 to be transformed into a parallelogram continues even when the container material 2 is sent to the container rotating device 5 through the container bottom forming step by the container bottom forming device 3 (FIG. 2). Have been.

In FIG. 4, the diagonal direction in which the rotary plate 44 is inserted is adjusted to the shorter diagonal line in the parallelogram cross section. As a result, the container material 2a is
4, the container material 2 when pushed upwards
a rises while being pushed outward by both sides of the rotating plate 44. Then, when the container material 2a is lifted to the uppermost position, the container material 2a comes into close contact with both sides of the rotating plate 44 due to the elastic restoring force of returning to the parallelogram shape in cross section. Therefore, the container material 2a is held by the rotating plate 44 without falling off without performing any fixing process.

The lower end of both sides of the rotary plate 44 is formed with a taper, that is, an inclined surface for securely inserting the container material 2a. Further, the width of the rotating plate 44 is not limited to a specific value, and may be any width as long as the restoring force of the container material 2a to be restored to the original cross-sectional shape can be sufficiently increased. Specifically, assuming that the cross-sectional shape of the container material 2a is a square shape or a rectangular shape, it is considered that a value approximately equal to or slightly larger than the length of the diagonal line of the square or the rectangle is considered. Can be

When the container material 2a is held by the rotating plate 44, in FIG. 3, the container rotating lever 52 swings and the rotating plate 44 rotates 90 °. Due to this rotation of the rotating plate 44, the container material 2a supported by the rotating plate 44 also
Rotate 0 °. Thus, the ears c, d of the container material 2a
(FIGS. 13 and 14) are changed from a direction facing the container transport direction F to a direction perpendicular to the transport direction F.

When the rotating plate 44 has completed the 90 ° rotation, FIG.
In, the lift lever 33 rotates downward, and the lifting rods 39a and 39b descend. In this case, the container material 2a is pushed down by the holding claw 42 provided at the upper end thereof by the lowering of the long lifting rod 39b. And the lifting rod 39b is at the lowest position (solid line).
At this point, the container material 2a is again lowered to the container transport position by the transport chains 4a and 4b, that is, the position where the container material 2a is held by the container transport claws 43.

If no measures are taken when pushing down the container material 2a, a part of the bottom surface of the container material 2a will hit the upper end of any one of the container transport claws 43, and There is a possibility that it cannot be inserted correctly. In order to solve this problem, when pressing down of the container material 2a by the holding claws 42 is started, in FIG. 4, the four guide blocks 58 are driven by the air cylinder 57 to move to the protruding positions (dashed lines). Therefore, the falling container material 2
“a” is guided by the guide block 58 moved to the projecting position, and is accurately inserted between the container carrying claws 43.
The container material 2a inserted between the container carrying claws 43 and turned in the 90 ° direction is then carried by the carrying chains 4a and 4b and sent to the next step, that is, the contents filling step.

The above description is directed to a flat-top type container without a plug as shown in FIG. However, as a flat-top type container, there is also a type in which a plug 59 is attached to a flat container top P as shown in FIG. When manufacturing a container provided with such a plug, it is necessary to provide a step for mounting the plug at any place of the molding and filling apparatus shown in FIGS.

FIG. 9 shows an example of a molding and filling apparatus provided with such a stage for mounting a plug. In this molding and filling apparatus, the plug mounting stage S is provided between the container bottom forming device 3 and the container rotating device 5.
The other configuration of the present molding and filling apparatus is exactly the same as the molding and filling apparatus of the type shown in FIG.

The plug mounting stage S includes a plug temporary mounting device 60 and a plug welding device 61.
The temporary plug mounting device 60 is configured by a plug hopper 62 containing a large number of plugs, and a parts feeder 63 for feeding the plugs one by one. The parts feeder 63 feeds the plugs one by one onto the container transport path, and the fed plugs 59 are fed as shown by arrows T in FIG.
It is inserted from the inside of the container material 2a into an opening 64 provided beforehand in the upper part of the container material 2a.

The container material 2a into which the plug 59 has been inserted, ie, temporarily attached, is transported by the transport chains 4a and 4b and is transported to the plug welding device 61. Spout welding device 6
1 can be configured using, for example, an ultrasonic welding device known per se, and when this ultrasonic welding device is used, ultrasonic waves are applied to the flange portion 65 of the plug 59,
The vibration caused by the ultrasonic waves causes the flange portion 65
Generates heat and is welded to the inner surface of the side wall of the container material 2a. After the spout 59 is welded, the container material 2 a is sent to the container rotating device 5. The processing by the container rotating device 5 and the subsequent processing are exactly the same as those of the former molding and filling apparatus shown in FIG. 6, and therefore the description thereof is omitted.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the embodiments. For example, the rotation angle of the rotating plate 44 is not necessarily limited to 90 °, but may be an integral multiple of 90 °.
In addition, the shape of the rotating plate 44 is not limited to a flat plate shape, but may be any other shape.

[0057]

According to the present invention, the direction of the container material is set to 90.
By rotating 整数 or an integral multiple thereof, the ear crests c and d (FIG. 12) of the container material can be directed in a direction perpendicular to the container transport direction. Therefore, even when the distance between two adjacent container materials in the container transport direction is set to be small, the ears c and d of the container materials protruding outside the side wall surface of the container do not collide with each other. The overall length of the molding and filling apparatus can be reduced by reducing the distance between two adjacent container materials in the container transport direction.

Further, according to the present invention, the direction of the container material can be reliably changed with a simple configuration. Moreover,
Since the container material is once lifted from the transport path of the container and rotated, there is no need to modify the transport system of the container material itself, and the structure is not complicated from this aspect as well.
