Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid member mounting method and device.

[0002]

2. Description of the Related Art As one form of a package for instant foods such as ramen, for example, as shown in FIG. 9, a cup-shaped container 1 having an upper opening, in which foods to be packaged are stored, There is a container 1 in which a sheet-shaped lid member 2 is adhered to the upper end portion and sealed. The reference numeral 2a is a projecting piece formed integrally with the lid member 2 and serves as a gripping portion when opening.

In order to manufacture such a package, conventionally, a separately formed lid member is supplied to the hopper. Then, the container containing the food is conveyed at a predetermined interval, and during the conveyance, the lid members stocked in the hopper are taken out one by one, placed on the container, and heat-sealed in that state.

[0004]

The above-mentioned conventional ones have various problems as described below. That is, before starting the operation of the lid member attaching device, it is necessary to first supply the lid member to the hopper, and the number of lid members that can be stored in the hopper at one time is limited. Therefore, the mounting process cannot be continuously performed for a long time. Therefore, considering the daily operating efficiency, not only is there a limit to the improvement of productivity, but also the supply to the hopper is complicated and the workability is poor. Moreover, a place for storing a separately formed lid member is also required.

In addition, recently, there are various types of packages, and the plane shape is not limited to a circular shape, but a rectangular shape (some have rounded vertices) or an elliptical shape (see FIG. 9)). Then, the lid member for such a packaging body has directionality, and when it is stored in the hopper, it has to be performed in consideration of its orientation, which makes the storage process in the hopper more complicated.

Further, since this type of device is generally versatile and can be used for mounting containers and lid members having different shapes, it is necessary to prepare hoppers of various sizes and shapes. However, it is not practical to prepare the hopper according to all the shapes from the viewpoint of storage space and the like, and it is also used for a plurality of types of lid members. Further, in the case of a special (non-circular) shape as described above, it is complicated to manufacture a hopper that conforms to the shape with high accuracy, and in many cases, it does not coincide completely.

Therefore, a gap is created between the inner shape of the hopper and the outer shape of the lid member, and the lid member is idle in the hopper. Therefore, even if the lid member is housed in the hopper with the correct orientation, the above-mentioned play changes the posture of the lid member in the hopper, and the correct posture (direction) when the lid member is taken out from the hopper. It may be in a state of being rotated by a predetermined angle from. Therefore, if the rotation angle is large, the container cannot be properly mounted, and the opening of the container cannot be closed, which may result in defective packaging. When the rotation angle is small, the opening of the container can be closed and the package can be sealed, but the appearance is deteriorated. Therefore, the yield is reduced.

The present invention has been made in view of the above background, and an object thereof is to continuously perform a series of processes from the manufacturing of the lid member to the mounting process of the lid member to the container. The mounting process can be speeded up, the number of products manufactured per unit time can be increased, the conventional manual mounting process on the hopper is not required, and the number of manual steps can be reduced as much as possible to simplify workability. It is an object of the present invention to provide a lid member mounting method and device that can be mounted in a container in a correct state even if it has a special shape, and that has a high yield.

[0009]

In order to achieve the above-mentioned object, in the lid member mounting method according to the present invention, a container having an upper opening is conveyed at predetermined intervals. Separately from this, while continuously pulling out the film material constituting the lid member to be attached to the opening of the container from the original roll, cut out into a predetermined shape at a predetermined timing during the withdrawal from the film material. Separated to form a lid member. Then, the transfer processing is performed by holding the cut-out lid member and covering the upper opening of the transported container. Further, the lid member thus transferred and the abutting portion of the container are adhered to each other (claim 1).

In the mounting of the lid member according to the present invention suitable for carrying out the above method, the transporting means for transporting the container having the upper opening and the film material constituting the lid member mounted on the container are wound up. A means for pulling out the film material from the original roll, a cutting means for cutting a predetermined position of the film material into the shape of the lid member, a container for holding the cut lid member, and being transported on the transport device. And a bonding means for bonding the contact surface between the lid member and the container to each other (claim 2).

The cut-out means may be composed of, for example, a pair of male and female dies, and a drive means for moving the male dies forward and backward with respect to the female dies at a predetermined timing. Item 3). When the mold is used as described above, a storage portion for temporarily holding the cut cover member in the female mold may be formed (claim 4). Further, as another configuration of the cutting means, a die roll having a blade portion of a predetermined shape on the film contact surface can be used (claim 5).

Further, in any of the above-mentioned constitutions, it is more preferable to add a collecting means for collecting the film material cut out by the lid member, on the downstream side of the cutting means (claim 6). Then, as the collecting means, for example, it may be wound on a take-up reel, cut into a predetermined length using a cutter, and store the cut chips in a tray or the like, or use a cutter. Various configurations can be adopted such as stacking a predetermined number of cut sheets and banding.

The lid member is manufactured by pulling out the film material from the original roll and cutting it into a predetermined shape during the pulling out. The manufactured lid member is held by the transferring means, the lid member is transferred onto the container moving on the conveying means, and the lid member and the container are sealed and integrated by using the bonding means. . This completes the mounting process of the lid member. That is, a series of processes from the production of the lid member to the adhesion and integration into the container are automatically and continuously performed.

Since the lid is manufactured by an integrated apparatus, it is easy to control the relative positional relationship between the direction of cutting the film material by the cutting means and the direction of the container. Even if there is a shape,
It is possible to control so that the conveying attitude of the container on the conveying means and the cutting direction have a predetermined relationship, and the lid member can be reliably mounted on the container.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a lid member mounting method and apparatus according to the present invention will be described in detail below with reference to the accompanying drawings. 1 to 3 show a first embodiment of the present invention, which is an example applied to an apparatus for manufacturing a package for cup noodles (shown in FIG. 9) in the present embodiment. As shown in the figure, the container 1 having the upper opening is sequentially transported on the transport device 10 in an aligned state at predetermined intervals. This kind of container 1
Has an inverted trapezoidal vertical cross section, the size of which increases as it goes to the upper part. Therefore, as shown in FIG. 2, the transfer device 10 includes the endless chains 11 arranged in parallel on both sides in the transfer direction, and the endless chains 11. A large number of flat plates 12 provided between the endless chains 11 are provided, and the flat plate 12 has three through holes 12a formed in a direction orthogonal to the transport direction. The size and shape of the through hole 12a are formed so as to correspond to the outer shape of the container 1, and match the outer shape of the container 1 at a predetermined position on the side surface. As a result, when the container 1 is supplied into the through hole 12a, it is caught at a predetermined position and the flat plate 12
The upper portion of the container 1 projects from the upper surface of the container. Then, by supplying the container 1 into the through hole 12a, the posture of the container 1 relative to the carrying direction is positioned.

In this example, the three containers 1 are conveyed in a horizontal row, and the lid members are attached to the three containers 1 at the same time. The number of pieces to be processed at the same time can be arbitrary by changing Further, the flat plate 12 is detachably attached to the endless chain 11 by a predetermined stopper, and when the size and shape of the container to be processed changes, the flat plate is changed accordingly. Also, the flat plate 12
It is also possible to set a through hole to be formed in a relatively large size and attach an attachment (a through hole having a predetermined shape is formed) in the through hole so as to correspond to different containers.

An original roll 13 and a preliminary original roll 13 'are arranged at a predetermined position above the conveying device 10. Then, the strip-shaped film 15, which is a film material, is continuously drawn out from the one original roll 13, and the strip-shaped film 15 is fed to the idle roller 16 and the feed roller 17.
It is adapted to be taken up by a take-up reel 18 located below and passed through a predetermined path.

The strip-shaped film 15 is made of a material which constitutes the lid member 2 to be mounted on the container 1, and the design of the lid member 2 is printed at a predetermined position. There are three printing positions in the direction orthogonal to the pull-out direction, and the arrangement interval is the conveyance device 10.
The arrangement interval of the through holes 12a of the flat plate 12 in FIG. Although not shown in the drawings, a positioning mark called an eye mark is printed on a side edge of the strip-shaped film 15 corresponding to a position where the lid member is printed.

On the other hand, the feed roller 17 serving as a drive source for pulling out the band-shaped film 15 at a predetermined speed receives the rotational force from the drive motor 19 and rotates intermittently at a predetermined speed. As the drive motor 19, a servo motor whose rotation speed can be controlled to be increased or decreased is used. The drive motor 19 is connected to the control device (CP
U) Driven on the basis of the control signal from 20, the control device 20 uses the photoelectric sensor 2 for detecting the above-mentioned eye mark.
A control signal is output based on the detection signal from 1.

That is, while the container 1 advances one pitch on the transport device 10, the strip film 15 also needs to advance one pitch. Therefore, the distance between the eye marks is detected by detecting the eye marks by the photoelectric sensor 21 (since the control device 20 knows the moving speed of the belt-shaped film 15, the time required to detect the front and rear eye marks). You can calculate the distance from). In addition, in the present embodiment, since the transport device 10 is operated at a constant speed, the detected one pitch of the belt-shaped film 15 is a predetermined time (1 of the transport device 10).
Drive motor 19 so that it moves in the pitch movement time)
Determine the rotation speed of.

As a result, when the cover members printed on the band-shaped film 15 have no gaps in printing and the band-shaped film 15 does not extend, and the cover members are evenly spaced, the drive motor 19 rotates at the same speed during rotation (described later). When there is a print misalignment and the eye mark spacing is different, the drive motor 1 is driven according to the misalignment.
9 is acceleration / deceleration controlled. That is, in this embodiment, the idle roller 16, the feed roller 17, and the drive motor 1 are
9, the control device 20 and the photoelectric sensor 21 constitute a means for drawing out the film material.

Further, in this embodiment, the film supplier 2
2, the strip-shaped film 1 from one original roll 13
After the pulling-out of 5 is completed, the strip-shaped film 13 ′ is pulled out from the spare original fabric roll 13, and
By connecting the rear end of the strip film 13 to the leading end of the strip film 13 ', the strip film can be continuously supplied. Therefore, both films 13, 13 '
Since the joint portion cannot be used as a lid member, the eye mark interval becomes long at least in the joint portion. In such a case, the rotation speed of the drive motor 19 is increased so that the lid member 2 can be supplied to the container 1 without coming off.
The film supplier 22 has a film end detection sensor 23, and when the sensor 23 detects the rear end of the film, the head of the next strip-shaped film 13 'is bonded to the rear end by a known mechanism. .

The take-up reel 18 is linked to a drive motor 25 via a powder clutch 24. The rotation speed of the drive motor 25 is the same as the take-up speed of the take-up reel 18.
It is set to be faster than the speed at which the band-shaped film 15 is pulled out by the feed roller 17. The speed difference is absorbed by the powder clutch 24 (the clutch is constantly slipping), and the rotation speed of the take-up reel 18 becomes slower than the rotation speed of the output shaft of the drive motor. As a result, the strip-shaped film 15 that has been pulled out is always in a state where a predetermined tension is applied.

The powder clutch 24 is interposed between the drive motor 25 and the take-up reel 18, causes a predetermined slip, and as described above, the take-up reel 18 is determined by the rotation speed of the drive motor 25. For absorbing the difference between the rotational speed of the take-up reel 18 and the rotational speed of the take-up reel 18 determined by the speed at which the strip-shaped film 15 is pulled out by the feed roller 17, and various power transmission mechanisms can be used as long as they have such a function. be able to. And in this embodiment,
The take-up reel 18, the powder clutch 24, and the drive motor 25 constitute a film material collecting means.

Further, in this embodiment, a punching device, which is a cutting means composed of a female die 28 and a male die 29, with the strip-shaped film 15 sandwiched therebetween is installed, and the female die 28 is attached to a fixed system such as a machine frame of a lid member mounting device. The male die 29 can be moved forward and backward toward the female die 28 by a cylinder 30 as a driving means.

Then, the female die 28 and the male die 29 are matched with the shape of the printed lid member, and when the male die 29 enters the female die 28 due to the extension of the cylinder 30, both die 2 are
The strip-shaped film 15 sandwiched between 8 and 29 is punched out at its printed portion (portion to be a lid member) and moves into the female mold 28. Then, the remaining film is taken up by the take-up reel 18 as described above.

The outside of the female die 28 (the strip film 15
A transfer device 31 for holding the punched lid member and mounting it on the container 1 is provided on the opposite side). The transfer device 31 includes a suction cup 33 that is inserted into the female mold 28 to adsorb the lid member, a cylinder 34 that moves the suction cup 33 forward and backward, and a base end of the cylinder 34 (a side opposite to the suction cup mounting side). Attached rotating shaft 3
5 and a drive motor 36 that is associated with the rotating shaft 35 and rotates the rotating shaft 35 forward and backward. Furthermore its sucker 3
A sealer 37 serving as an adhesive means is arranged so as to surround the periphery of 3. The sealer 37 can be moved forward and backward independently of the suction cup 33 by a drive source (not shown). The shape of the sealer 37 is the same as the shape of the upper end opening of the container 1. Also, the suction cup 33
The shape of is a size smaller than the shape of the sealer 37. The suction cup 33 may be replaced with a suction jig provided with suction means.

By rotating the drive motor 36 forward and backward, the cylinder 34 remains horizontal and the suction cup 33 faces the female die 28 at the first position as shown in FIG. When the cylinder 34 is rotated 90 degrees, the cylinder 34 is in the vertical state and the suction cups 33 are positioned downward at the second position alternately at a predetermined timing. In this embodiment, by rotating the drive motor 36 forward and backward, the two positions described above are reciprocated. For example, a predetermined link and / or a cam is used to reverse the rotation direction of the rotary shaft 35 (drive). The motors may rotate in the same direction).

Next, the operation of the above embodiment will be described. First, the feed roller 17 rotates at a predetermined speed, and the strip film 15 is continuously drawn from the original roll 13. Then, the strip-shaped film 15 is converted by the feed roller 17 in the moving direction to the lower side, and the female die 28 and the male die 29 are moved.
It passes through the space and is continuously wound around the winding reel 18. Then, while the photoelectric sensor 21 detects the eye mark provided on the band-shaped film 15, the band-shaped film 15 is conveyed by one pitch (interval between the front and rear eye marks) at a predetermined speed, and the printed portion corresponding to the lid member is When it is located between the two molds 28, 29, it is temporarily stopped.

At the time of this temporary stop, the cylinder 30 connected to the male die 29 expands, the male die 29 advances toward the strip film 15, and enters the female die 28. Then both types 2
The printed portion of the strip-shaped film 15 sandwiched between 8 and 29 is punched out to form a lid member. At this time, the cylinder 34 of the transfer device 31 also expands at the same time, and the suction cup 33 moves the female mold 28.
Since it has entered the inside, the lid member punched out from the band-shaped film 15 is held by the suction cup 33.

Next, the cylinders 30 and 34 are contracted, and the male die 29 and the suction cup 33 are retracted. Then, the feed roller 17 rotates at a predetermined speed to position the next printed portion of the lid member between the two molds 28 and 29, and
The punched strip-shaped film 15 is taken up by the take-up reel 18.

The transfer device 31 includes the drive motor 3
6 is rotated to rotate the cylinder 34 clockwise by 90 degrees about the rotary shaft 35 from the state of FIG. 1, and the suction cup 33 holding the lid member 2 is located at the lowermost end as shown in FIG. 3 (A). Let

At this time, the carrier device 10 also intermittently moves at a predetermined timing, and is temporarily stopped with the container 1 positioned below the suction cup 33. In this state, the cylinder 34 is extended to lower the suction cup 33, and the lid member 2 is brought into contact with the upper portion of the container 1 ((B) in the same figure). In this state, the lid member 2 maintains the state of being sucked by the suction cup 33.

Next, the sealer 37 is lowered (simultaneously (C)), the sealer 37 is brought into contact with the position corresponding to the contact portion between the lid member 2 and the container 1, and the container 1 is heated at a predetermined pressure while heating the lid member 2. Bias to the side. As a result, the lid member 2 and the container 1 are heat-sealed, and the lid member mounting process is completed.

Thereafter, the reverse process to the above is performed to prepare for the next mounting process of the lid member. That is, in the transfer device 31, the cylinder 34 contracts and the suction cup 33 and the sealer 37 rise. At this time, since the lid member 2 and the container 1 are already heat-sealed and integrated, the lid member 2 is separated from the suction cup 33 as the suction cup 33 rises. And sucker 3
3. When the sealer 37 has risen to the position shown in FIG. 3 (A), the drive motor 36 is rotated in the reverse direction to rotate the cylinder 34 counterclockwise by 90 degrees and return to the upper position shown in FIG. Further, the transport device 10 is also moved by one pitch, and the next container is positioned below the transfer device 31 as shown in FIG.

As described above, in this embodiment, the lid member 2 is punched out from the band-shaped film 15 by using the two molds 28 and 29, and the punched lid member 2 is mounted on the container 1. There is no need to manually attach the lid member to the hopper as in the conventional case, and a series of processes from the production of the lid member to the attachment to the container can be automatically performed continuously, and the production efficiency is improved. Also, the mounting process of the lid member,
At least one roll of the original roll 13 can be continuously performed. Further, in the present embodiment, by providing the film supplier 22, when one roll of the original fabric 13 is used, the next roll is automatically performed. From the original roll 13 'to the strip film 1
Since 5'is supplied, continuous operation is possible for a long time.

Further, the orientation of the container 1 with respect to the transport device 10 is uniquely and accurately determined, and the strip-shaped film 15 is used.
Since the lid member 2 punched out from the container is held by the suction cup 33 as it is and transferred onto the container 1, the relative positional relationship between the lid member and the container can be accurately arranged, and the conventional positioning can be performed. Occurrence of defective products due to defects is suppressed as much as possible, and the yield is improved.

FIG. 4 shows an essential part of the second embodiment of the present invention. In this embodiment, unlike the above-described embodiment, the feed roller 17 is continuously operated (not temporarily stopped for die cutting) to improve the number of products manufactured per unit time. That is, in this embodiment, the die member 40 is used to cut out the lid member from the band-shaped film 15.
The die roll 40 is composed of a pair of rollers arranged to face each other with the strip film 15 interposed therebetween.
Side surface (film contact surface) is flat, and the other roller 40
A blade portion is formed on the side surface of b according to the shape of the lid member to be manufactured, and the blade member is pressed against the strip film 15 to cut out the lid member having a predetermined shape from the strip film 15. In this embodiment, this die roll 40 constitutes a cutting means.

Immediately below the die roll 40, the suction belt 41 and the above-mentioned transfer device 31 are arranged so as to face each other with the strip film 15 interposed therebetween. This suction belt 4
Although not shown in the figure, 1 has a large number of through holes formed in the belt surface, and the through holes are linked with a suction pump so that the belt film can be sucked at a predetermined timing to adsorb the belt-shaped film 15 located on the belt surface. It has become. Therefore,
A predetermined portion of the strip-shaped film 15 is gradually separated by the die roll 40, and the suction of the suction belt 41 is started at least before the cover member is formed by completely cutting the belt-shaped film 15, so that the separated cover member 2 is removed. It never falls.

Further, the suction belt 41 is adjusted so that the belt surface moves at the same speed as the feeding speed of the belt-shaped film 15 by the feed roller 17. Then, after passing through the die roll 40, the belt-shaped film 15 and the lid member 2 are conveyed while being suction-held by the suction belt 41 while being cut and separated, and the lid member faces the suction cup 33 of the transfer device 31. Cylinder 34 expands and sucker 33
Comes into contact with the lid member 2 and sucks and holds it. After that, when the cylinder 34 contracts, the lid member held by the suction cup 33 separates from the suction belt 41. At this time, in order to smoothly perform the separation, it is preferable to temporarily stop the suction processing of the suction belt 41. When the holding force of the suction cup 33 is stronger than the suction force of the suction belt 41, the suction belt 41
May be continuously sucked.

By doing so, it is not necessary to move the male die 29 forward and backward to manufacture the lid member, the time required for the movement can be omitted, and the processing can be performed at higher speed.
The suction cup 33 moves on the suction belt 41.
The rotation of the suction belt may be temporarily stopped so as not to apply an unreasonable force to the transfer device 31 when it comes into contact with the die roll 40 and the feed roller 17 accordingly.
Also pause). Even in this way, the stop time is
Compared with the temporary stop due to the movement of the male die 29 in the first mode, the speed is very small, so high speed is ensured. Since the other configurations and effects are the same as those of the first embodiment described above, detailed description thereof will be omitted.

FIG. 5 shows a third embodiment of the present invention.
This embodiment is based on the above-mentioned first embodiment, and is an improvement of the processing mechanism (collecting means) of the strip film 15 after the lid member is cut off. That is, in the first embodiment, the strip-shaped film 15 after use is wound around the take-up reel 18. However, when the film is wound in such a manner, the diameter increases as the winding progresses, so that the drive motor 25 is When operating at a constant speed, the speed difference becomes even larger. Therefore, the load on the powder clutch 24 increases. Then, in order to eliminate such a situation, it is necessary to gradually reduce the speed of the drive motor 25 during rotation. Furthermore, take-up reel 1
Since the strip-shaped film 15 wound around 8 is in a perforated state in which the portion of the lid member 2 is pulled out, it is difficult to wind up the film neatly.

Therefore, in the present embodiment, the cutter device 44 is installed below both the molds 28 and 29, and the tray 45 is installed further below the cutter device 44 to drive the take-up reel 18 and the take-up reel 18 in the first embodiment. Mechanisms 24 and 25 were removed. Then, the cutter device 44 and the tray 4
5 constitutes a collecting means.

As a result, the strip-shaped film 15 that has passed through both the molds 28 and 29 is cut by the cutter device 44 into predetermined lengths. Then, the cut chips 46 are accumulated in the tray 45. When the chips 46 stored in the tray 45 are accumulated to some extent, they are taken out and discarded. Since the other configurations and effects are the same as those of the first embodiment described above, detailed description thereof will be omitted. And, of course, the third mode can be applied to the second mode, which is not shown.

FIG. 6 is an improvement of the third embodiment, in which the sheet 47 cut by the cutter device 44 is banded. That is, when the chips 45 are received by the tray 45 as in the third embodiment, the chips 46 are
When the two are entangled with each other, they cannot be efficiently stored in the tray 45 and become bulky. Furthermore, when discarding the chips 46 stored in the tray 45, it is necessary to be careful so as not to scatter around, which is complicated.

Therefore, in the present embodiment, the cutter device 44
The cut belt 4 is provided with a suction belt 48 on the downstream side of the sheet.
7 is moved horizontally while temporarily adsorbing, and a carry-out conveyor 49 is arranged below the suction belt 48, and a banding machine 50 is provided on the downstream side of the carry-out conveyor 49.
Is installed. Then, the cutter device 44, the suction belt 48, the carry-out conveyor 49, and the banding machine 50.
Constitutes the recovery means of the present invention.

According to this structure, when the tip of the belt-shaped film 15 reaches the suction belt 48, the tip portion is sucked by the suction belt and conveyed while maintaining the horizontal state, and if it is pulled out by a predetermined length, the cutter. Device 44
The sheet is cut into sheets 47 and conveyed as they are. When the suction belt 48 is conveyed to the predetermined position, the suction process of the suction belt 48 is stopped. Then, since the suction force is lost, the suction force naturally falls and is transferred onto the carry-out conveyor 49 below. At this time, the carry-out conveyor 49 is temporarily stopped.

Then, the sheet 47 is placed on the carry-out conveyor 49.
When a predetermined number of sheets have been stacked, the carry-out conveyor 49 is driven to supply the stacked belt to the banding machine 50, and the stacked sheet bundle is bundled therein. With such a configuration, the sheets 47 are banded so that they are efficiently stacked, and the cut sheets 47 become a lump so that they do not scatter around and are easy to handle. The fourth mode can also be applied to any of the above-described first and second modes. Other configurations and operational effects are the same as those of the above-described respective embodiments, and thus detailed description thereof will be omitted.

FIG. 7 shows a fifth mode of the present invention. This mode is based on the first mode described above, and relates to improvement of post-treatment of the lid member 2 manufactured by punching with both molds. That is, in the present embodiment, the female die 28 'is made thicker and the internal space (storage portion) 51 has a function of temporarily storing the cut lid member 2. Specifically, a locking piece 52 that protrudes inward is attached to the opening peripheral edge of the female die 28 'on the lid member take-out side (the side opposite to the male die 29). This locking piece 52
The outer peripheral edge of the punched lid member 2 is locked to the
The separation of the lid member 2 from 8'is suppressed.

Further, a biasing mechanism 53 is arranged inside the male die 29 so that the punched lid member 2 is surely positioned on the opening side of the female die 28 '. The urging mechanism 53 includes a cylinder 54 and a push plate 55 attached to the tip of the cylinder rod of the cylinder 54.
4 moves with the male die 29, and when the cylinder 54 extends, the push plate 5 attached to the tip of the cylinder rod.
5 penetrates deeply into the internal space 51 of the female die 28 ', and the cut lid member 2 is pushed into the opening side of the female die 28' (see FIG. 7B).

With such a construction, for example, before the lid member mounting process is started, a predetermined number of lid members 2 are manufactured by punching a predetermined position while moving the band-shaped film 15, and the lid members 2 are stocked in the female mold 28 '. be able to. Then
For example, a strip film 15 from one original roll 13
And the distance between the front and rear lid members printed at the joining portion of the strip-shaped film 15 'from another original roll 13' is long, and a lid for attaching the lid member to the next container 1 even if fast-forwarding. Even when the production of the members is not in time, the lid member 2 stocked in the female mold 28 ′ can be mounted on the container 1, and the container 1 transported on the transport device 10 can be Can be securely attached without coming off. As a result, the feeding speed of the container 1 and the strip-shaped film 15 can be determined by noting the feeding at the above-mentioned joining portion of the films but focusing only on the normal movement of one pitch, so that the driving speed should be higher. Is possible and productivity is further improved.

Further, by adopting such a configuration, even if there is something abnormal on the transfer device and the transfer device is temporarily stopped,
The lid member can be manufactured by continuously pulling out the strip-shaped film 15 side, and conversely, even when there is an abnormality on the strip-shaped film 15 side and production of the lid member is temporarily stopped, the female mold 2
It is possible to supply to the container by using the lid member stocked in 8 '. As a result, the possibility that the entire apparatus will stop is suppressed as much as possible, and in that respect as well, productivity is improved. In addition,
This embodiment can be applied to any of the above-mentioned respective embodiments. In addition, the urging mechanism is not limited to the one that directly presses the lid member by the above-mentioned cylinder, but air may be blown out. The point is that the punched lid member ensures the female mold 28 '. It suffices if it can move to the opening side of.

In each of the above-mentioned embodiments, since the lid member is manufactured when the strip-shaped film 15 is moving downward, the transfer device 31 is also rotated in the 90 ° angle range. However, the present invention is not limited to this, and for example, the lid member may be manufactured when the strip-shaped film is horizontally moved, and the transfer device may be rotated by 180 degrees.

That is, an example (sixth embodiment) of the embodiment in which it is rotated by 180 degrees can be constructed as shown in FIG. As shown in the figure, the strip-shaped films 15 and 15 ′ pulled out from the original fabric rolls 13 and 13 ′ mounted on the film supply 22 are stretched around an idle roller 16 and a feed roller 17, and by the feed roller 17. The course is changed and it comes to move horizontally.

The cylinder 3 is provided above the horizontally moving path.
A male die 29 that moves up and down by 0 is disposed, and a female die 28 is disposed below the male die 29 with the strip-shaped film 15 interposed therebetween. Further, below the female die 28, a transfer device 31 is arranged.

In this transfer device 31, the rotary shaft 35 is 1
The first position in which the suction cup 33 is located above and faces the female mold 28 as shown by the solid line in the figure.
As shown by the chain double-dashed line in the figure, the suction cups 33 are located below and alternate between the second position facing the container 1. Then, the cylinder 34 expands and contracts at each position, holds the lid member in the female mold 28 at the first position, and attaches the held lid member 2 to the container 1 at the second position. The holding mechanism and the mounting mechanism are the same as those in the above-described examples.

With such a configuration, the distance for moving the suction cup 33 becomes long, which is inferior in terms of high speed, but, for example, when the first and second positions are alternately positioned, the forward and reverse rotation is not performed. It is also possible to rotate them by 180 degrees in the same direction, and the drive mechanism can be simplified. Furthermore, since the lid member punched out by the male mold 29 and the female mold 28 maintains the horizontal state, the gravity is evenly applied. Therefore, the container 1 can be surely held in a normal posture without being biased.
It is more reliably performed to put it in a normal state when it is attached to. In particular, when a predetermined number of lid members punched into the female mold are stocked as in the fifth embodiment described above, there is no risk of the lid members curving during stocking, which is preferable.

Since the other constructions and effects are the same as those of the above-mentioned respective embodiments, the same reference numerals are given and detailed description thereof will be omitted. Thus, it goes without saying that the present embodiment shown in FIG. 8 is not limited to the one shown in the drawings, and can be appropriately combined with the characteristic configurations of the above-described embodiments. Furthermore, the rotation angle when moving between the first and second positions in the transfer device is not limited to the above-mentioned 90 degrees and 180 degrees, and it goes without saying that it can take any angle.

[0059]

As described above, in the lid member mounting method and apparatus according to the present invention, a series of processes from the manufacturing of the lid member to the mounting process of the lid member in the container can be continuously performed. As a result, it is not necessary to manually attach the hopper to the hopper, the number of steps required by the human is reduced as much as possible, the workability is simplified, the attaching process of the lid member is speeded up, and the unit time is reduced. The number of products manufactured per unit can be increased. In addition, since it can be centrally managed, even if it has a special shape, it can be reliably attached to the container in a correct state, and the yield is improved.

According to the third aspect of the invention, since the lid member can be stocked in the female die, the interval between punching positions such as the joint portion of the film materials becomes long, and the film material is placed within a desired time. Even when the fixed amount cannot be moved, the stock lid member can supply the lid member to the container. Therefore, the lid cannot be attached to the container, and the container becomes a defective product, and the transporting means is not temporarily stopped to reduce the productivity, so that it is possible to further increase the speed and improve the yield.
