Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an apparatus for simultaneously forming and bonding a tension ring to a container lid.

<Background Art> Recently, containers have been developed in which a tear weakening line extending from a tear-off tab protruding from the skirt portion of the container lid all the way to the top surface is provided on the container lid body, and the container can be easily opened by pulling the tear-off tab. Lids are popular. In this type of container lid, it is necessary to pull up the tear tab with considerable force when opening the lid, and therefore, the tear tab is made relatively long or equipped with a suitable tension piece. Makes opening easier.

However, a relatively long tear-off tab has the disadvantage that a lot of material is wasted when the container lid is preformed from sheet metal, which increases the manufacturing cost of the container lid. In addition, when attaching a tension piece to the tear-off tab on a container lid, it has traditionally been
Connections are made by means such as riveting or clamping, but these methods require a lot of time and effort during the manufacturing process, and the manufacturing cost increases.
The connection part is fragile and there is a risk of it being severed before the package is opened.

In order to solve the above-mentioned problems, a substantially cylindrical annular preform is formed, and the free end of the tear-off tab of the container lid and a portion of the preform can overlap with each other. Positioning the container lid and the preformed body, and then curling the peripheral edge of the preformed body in the radial direction to form a ring, and rolling the tear-off tab into the ring to join the two together. A manufacturing method and device for manufacturing container lids with tension rings were proposed by Vikanders in Sweden, and a patent application has been filed (patent application).
No. 58-13855 (see Japanese Patent Application Laid-Open No. 59-144536) and Japanese Patent Application No. 58-13856 (see Japanese Patent Application Laid-Open No. 59-144537). In this type of container lid with a tension ring, the molding of the container lid includes a preform forming means that forms a substantially annular preform, and a position where the preform is joined to a tear-off tab of the container lid. A preform supply means for supplying a preform, a container lid supply means for supplying a container lid, and a tension ring forming and forming method for forming a preform abutted against a receiving pocket of the container lid into a tension ring and simultaneously joining this to the container lid. This is easily accomplished by a device consisting essentially of: a coupling means;

In such a case, in order to obtain a container lid with a tension ring with stable quality at a low cost, a substantially cylindrical annular pre-formed body is formed at a sufficiently high speed, and the formed pre-formed body is used as a tension ring and then formed at a higher speed. It is required to be formed into a shape and to bond sufficiently firmly to the tear tab of the container lid.

Therefore, in order to satisfy the above-mentioned requirements, the applicant improved the apparatus for forming and joining a container lid with a tension ring having the above-described configuration, and formed and joined the tension ring at a sufficiently high speed and with sufficient strength. proposed a device that can simultaneously form a tension ring and bond it to a container lid. Such apparatus includes preform forming means, tension ring forming and bonding means,
comprising a container lid transfer means and a bond strengthening means,
The preform forming means forms a substantially cylindrical annular preform, and the tension ring forming and connecting means overlaps a portion of the preform and a free portion of the tear-off tab of the container lid. In this state, the peripheral edge of the preformed body is curled in the radial direction to form a ring, and the tearing tab is rolled into the ring to connect the two, and the container lid transfer means moves the container to which the tension ring is connected. transferring the lid from the tension ring forming and joining means to the joining reinforcement means, the joining reinforcement means pressurizing and deforming the joint between the tear-off tab of the transported container lid and the tension ring to strengthen the joint; The container lid with tension ring is thus formed as required.

In such devices, if the preform is not fed as required to the tension ring forming and joining means, a so-called no-ring container lid occurs, which is then transferred via the container lid transfer means. will be transferred to the bond strengthening means and therefore,
In order to prevent the above-mentioned transfer, monitoring means are provided on the container lid transfer means for monitoring the container lid of the knolling.

However, in the above-mentioned apparatus, since the monitoring means is configured to stop the entire apparatus when it detects a no-ring container lid, there is a problem in that the operating efficiency of the apparatus is reduced.

OBJECTS OF THE INVENTION The main object of the invention is to monitor a container lid with a tension ring transported by a container lid transport means,
To provide an improved device for forming and simultaneously bonding a tension ring to a container lid, which can reliably eliminate this in the case of a no-ring container lid to avoid being transferred to a reinforcing bonding means. It is.

The tear-off tab of the container lid is bent as required, and then the peripheral edge of the preform is radially curled to form a ring in the tension ring forming and joining zone G, and the tear-off tab of the container lid is inserted into the ring. The two are then rolled up and transported to the discharge area H. Furthermore, the container lid transfer means 18 (described later) receives the container lid to which the tension ring is attached from the tension ring and coupling means 16 in the discharge area H, conveys it in the direction of the arrow, and carries it out to the transfer area I. The bond reinforcing means 20 receives the container lid to which the tension ring has been bonded from the container lid transfer means 18 in the transfer zone I, conveys it in the direction of the arrow, and separates the tear-off tab of the container lid and the tension ring in the pressurized deformation zone J. After applying pressure and deformation to the mutually wrapped joint with a part of the material to strengthen the joint, the material is conveyed to the delivery area K. The configurations and effects of each of the above-mentioned preformed body forming means 10, preformed body supplying means 12, container lid supplying means 14, tension ring forming and bonding means 16, and bonding reinforcement means 20 are disclosed in the applicant's application.

(see Japanese Patent Application No. 1983-65287)
(See Publication No. 33931), Japanese Patent Application No. 58-65288 (Refer to Publication No.
63-33932) and Japanese Patent Application No. 58-65290 (see JP-A-59-191534).

Next, the container lid transfer means 18 will be explained in detail with reference to FIGS. 2 to 8. In FIGS. 2 and 3, a specific example of container lid transfer means 1 is shown.

A rotary conveyance board 30 is fixed to the upper end of the hollow cylindrical body 26 by mounting screws 28 . The hollow cylindrical body 26 is drivingly connected to a drive source such as an electric motor through a suitable transmission means, so that the rotary conveying plate 30 is rotated in the direction shown by the arrow 32 (second direction).
(counterclockwise in the figure).
A plurality of container lid receiving blocks 34 are fixed to the outer periphery of the rotary conveyance plate 30 with mounting screws 35 at equal intervals in the circumferential direction. At the upper end of each of the blocks 34, a container lid receiving pocket 36 is provided, as shown in FIG. Each container lid receiving pocket 36, as easily understood from FIG. It is set to about half of that. In the vertically intermediate portion of the pocket 36, a groove 42 is provided on the outer surface of the block 34 and extends through the block 34 in the circumferential direction. The radial depth of this groove 42 adjoining the pocket 36 is considerably greater than the radial depth of the pocket 36. The block 34 as described above has a pocket 3 as shown in FIG.
A cylindrical permanent magnet 44 is embedded in the bottom wall located above the portion where the groove 42 of No. 6 exists and the bottom wall located below that portion.

Further, the container lid transfer means 18 of the specific example includes a stationary guide rail 4 disposed along the outer circumferential surface of the rotary conveyance board 30 at a predetermined interval with respect to the outer circumferential surface.
It is equipped with 6. The stationary guide rail 46 is
When viewed in the rotational direction of the rotary conveyance plate 30 indicated by 2, it extends over substantially the entire range from the discharge zone H to the transfer zone I, except for the exclusion zone J (FIG. 2). That is, in the specific example, an upstream stationary guide rail is provided in the upstream transport area L from the discharge area H to the upstream side of the monitoring area K that is located upstream of the exclusion area J when viewed in the rotation direction shown by the arrow 32. A downstream stationary guide rail 46a is provided in the downstream conveying area M from the downstream end of the exclusion area J to the transferring area I when viewed in the rotational direction shown by the arrow 32.
b is provided. Upstream stationary guide rail 46
a and the downstream stationary guide rail 46b are support legs 48
The inner surface 50 of the container lid 3 is supported at a predetermined distance from the outer surface of the block 34.
The skirt walls 40 of the blocks 8 and 8 are positioned at intervals of approximately half the height of the skirt walls 40, and their upper surfaces 52 are positioned slightly lower than the height of the upper surfaces of the blocks 34 (in FIG. 3, the upstream side stationary Only the guide rail 46a is shown).

In the illustrated embodiment, an upper guide rail 54 is also provided in conjunction with the stationary guide rail 46, as shown in FIGS. 2 and 3. The upper guide rail 54a located on the upstream side extends from the downstream side of the discharge area H to the upstream end of the monitoring area K when viewed in the rotation direction shown by the arrow 32, and the upper guide rail 54b located on the downstream side extends from the downstream side of the discharge area H to the upstream end of the monitoring area K. , extending from the upstream end of exclusion zone J to transfer zone I, viewed in the direction of rotation indicated by arrow 32 (see FIG. 2). The upper guide rails 54a and 54b are connected to each other via support members 56 (only one is shown in FIG. 3), which are spaced apart from each other on the outer upper surfaces of the upstream stationary guide rail 46a and the downstream stationary guide rail 46b. It is supported by these. The radially inner lower surfaces of the upper guide rails 54a and 54b have a tension ring 58 coupled to a container lid 38 which is accommodated and transported in the pocket 36.
(only the upper guide rail 54a is shown in FIG. 3) and prevents upward displacement of the container lid 38 and the tension ring 58 coupled thereto.

In the illustrated example, the outer peripheral portion of the upper stationary guide rail 54b corresponding to the exclusion zone J is further cut out, and the opening of the discharge sheet 60 is positioned in this cutout. Referring also to FIG. 8, the upper wall 62 of the ejection sheet 60 is located above the upper guide rail 54b, and its lower wall 64 is located below the block 34, which is moved in the direction indicated by the arrow 32, thus Container lid 38 received in pocket 36 of block 34 is transported through an opening in discharge sheet 60 in the direction indicated by arrow 32.

The above-mentioned container lid transfer means 18 is used to monitor whether or not the container lid, which has been properly connected to the container lid at the same time as forming the tension ring by the tension ring forming and joining means 16, is being transferred. A monitoring means 66 is provided. Referring to FIGS. 2, 4, and 7, a monitoring means 66 is disposed in the monitoring area K, and a first detection means 68 and a second detection means 7
It has 0. In a specific example, the first detection means 68 includes a light emitting element 72 made of a light emitting diode or the like and a light receiving element 74 made of a photovoltaic cell or the like, and the second detection means 70 includes a detector 76 made of a proximity sensor or the like. It is configured. Referring to FIG. 8 together with FIG. 7, the monitoring means 66 includes a holding member 78 having a U-shaped cross section.
8 is attached to a mounting bracket 80 fixed to the upstream side wall of the discharge sheet 60. An upper horizontal portion 78a protruding inward in the radial direction of this holding member 78

A light receiving element 74 is fixed to the lower horizontal portion 78b that protrudes inward in the radial direction. Light projecting element 7
The light receiving element 74 is positioned slightly outward from the outer surface of the container lid receiving block 34 provided on the rotary conveyance board 30 so as to project light downward.
is positioned so as to receive the light projected from the light projecting element 72. Detector 76 is also positioned to detect the presence of tension ring 58 coupled to container lid 38 that is received and transported in container lid receiving pocket 36. Therefore, when the container lid 38 to which the tension ring 58 is coupled is transferred between the light emitting element 72 and the light receiving element 74, the light emitting element 72
The light from the container does not reach the light receiving element 74, and thus the first detection means 68 detects the presence of the container lid 38. The detector 76 also performs a sensing operation when the tensioning ring 58 coupled to the container lid 38 is below it, and thus the second detection means 70 detects the presence of the tensioning ring 58. In the monitoring means 66 as described above, when the first detecting means 68 detects the container lid 38 and the second detecting means 70 detects the tension ring 58 in the monitoring area K, if the first detecting means 68 detects the container lid 38 and the second detecting means 70 detects the tension ring 58, the On the other hand, if the first detection means 68 detects the container lid 38 but the second detection means 70 does not detect the tension ring 58. In this case, the tension ring 58 is not coupled to the container lid 38 housed in the pocket 36 (that is, the container lid is a so-called no-ring container lid). In the monitoring area K, such monitoring means 66
The presence of the container lid 38 and the tension ring 58 are simultaneously sensed, and a no-ring signal is generated when the container lid 38 and the tension ring 58 coupled thereto are not simultaneously detected.

The container lid transfer means 18 is further provided with an ejecting means 82 for removing the no-ring container lid 38 accommodated in the container lid receiving pocket 36 when a no-ring signal is generated. Second

Fixed. A mounting bracket 90 is fixed to the upper surface of the mounting member 86, and a control valve 9 is mounted on the mounting bracket 90.
2 is installed. The illustrated control valve 92 has a control valve body 94 in which a passage is formed, and an electromagnetic solenoid 96 having a valve member in the control valve body 94.
is installed. A valve member (not shown) is disposed in the passageway of the control valve body 94 and normally closes the passageway, but opens the passageway when the electromagnetic solenoid 96 is energized. A supply side connection part 94a in which a supply port is formed is provided on one end side of the control valve main body 94, and a discharge side connection part 94a in which a discharge port is formed in the other end side.
4b is provided. Although not shown, the supply side connection portion 94a of the control valve body 94 is connected to a compressed air supply source such as a compressor via a connection member. Further, the discharge side connection portion 94b of the control valve main body 94 includes an L-shaped connecting pipe 98, a connecting pipe 100,
and air supply member 104 via connection member 102
It is connected to the. A flange portion 104a is provided at the middle portion of the air supply member 104, and this flange portion 104a is fixed to a support member 106 attached to a mounting member 86 by a mounting screw 108. The support member 106 has a mounting screw 112 inserted through a long hole 110 formed in the inner end of the mounting member 86.
The air supply member 104 is attached by screwing the air supply member 104, and therefore, as can be easily understood from FIG. 4, the arrangement position of the air supply member 104 can be adjusted.
A sleeve member 114 for defining an exhaust port is fitted into the lower part of the air supply member 104 so as to be slidable in the vertical direction. A step is provided on the lower outer circumferential surface of the sleeve member 114, and an annular ring member 116 and the support member 1 are attached to this step.
06, a coil spring 118 is interposed between the coil spring 118 and the coil spring 118. As described above, the sleeve member 114
is biased downward by the action of the coil spring 118, protrudes slightly from the lower surface of the air supply member 104, and its lower surface is brought into contact with the upper surface of the rotary conveyance plate 30.

On the other hand, the rotary conveyance plate 30 described above has a plurality of air passages 120 (FIGS. 3 and 8) corresponding to each of the pockets 36 of the container lid receiving block 34.
is provided. One end of the air passage 120 opens to the upper surface of the rotary conveyance board 30, and the other end opens to the circumferential side of the portion of the rotary conveyance board 30 where the block 34 is attached. And each block 3
A through hole 122 communicating with the opening on the other end side of the corresponding air passage 120 is provided in the bottom wall of the pocket 36 of No. 4.

The removal means 82 as described above includes a connecting member (not shown), a control valve main body 94, an L-shaped connecting pipe 98, a connecting pipe 100, a connecting member 102, and a passage provided in the air supply member 104 and a sleeve. The interior space of member 114 constitutes a first flow path of an air supply flow path for conducting compressed air to pocket 36 (thus, the first flow path is configured to conduct compressed air from a source of compressed air). air passage 12 provided in the rotary conveyance plate 30)
0 and the through holes 122 provided in the block 34 communicating therewith constitute a second flow path of the air supply flow path for guiding compressed air to the pocket 36 (therefore, a second flow path). The flow path guides the compressed air supplied through the first flow path from the top surface of the rotary conveyance plate 30 to the pocket 36 of the block 34). The first flow path and each second flow path are connected to pockets 3 provided in the block 34, as shown in FIG.
6 is in the exclusion zone J, the second flow path corresponding to the pocket 36 in the exclusion zone J is in communication with the first flow path. In a specific example, the inner diameter of the sleeve member 114 corresponds to a predetermined range in the exclusion zone J, and the discharge port of the first flow path is set larger than the supply port of each second flow path. Therefore, in a state where the control valve 92 opens the first flow path, the supply port of the second flow path opens the first flow path as the rotary transfer plate 30 rotates in the direction shown by the arrow 32.
Compressed air flows into the air supply flow path from a point where the supply port aligns with an upstream portion of the outlet of the first flow path to a point where the supply port aligns with a downstream portion of the outlet of the first flow path. Pocket 3 in exclusion zone J through
6 will be sent.

In the specific example, a safety switch 121 is further provided downstream of the exclusion zone J (FIG. 4).
This safety switch 121 is composed of, for example, a micro switch.

Next, the effects of the container lid transfer means 18 described above will be explained.

Referring mainly to FIGS. 2, 6, 7, and 8, the arrow 3 is
The container lid receiving block 34, pivoting in the direction indicated at 2, reaches the discharge area H in synchronism with the tension ring forming and connecting means 16. In emission area H,
A pocket (not shown) provided in the tension ring forming and coupling means 16 and a container lid receiving pocket 36 provided in the block 34 face each other in close proximity and are accommodated in the tension ring forming and coupling means 16. The container lid is transferred to the pocket 36 of the block 34. When the block 34 pivots from the discharge area H in the direction shown by the arrow 32 and the tension ring forming and coupling means 16 also pivots in a predetermined direction, the container lid accommodated in the pocket of the tension ring formation and coupling means 16 remains stationary on the upstream side. The upstream end of the guide rail 46a restrains the pocket 36 of the block 34, thereby smoothly transferring the container lid to the desired position on the block 34 as desired. Once thus delivered, the container lid 38 and the tension ring 58 coupled thereto are received in the pocket 36 of the block 34, as shown in FIG.
Permanent magnet 44 (seventh magnet) embedded in block 34
(Fig. 8).
That is, the container lid 38 and the tension ring 58 are in a state in which the top wall 126 of the container lid 38 is located radially inward, the tear-off tab piece 128 is located at the uppermost position, and the tear-off tab piece 128 is free. A tension ring 58 coupled to the end projects radially outwardly (seventh
(See also figure). Thereafter, the container lid 38 and the tension ring 58 coupled thereto move from the discharge area H to the upstream conveying area L, to the monitoring area J, and to the downstream conveying area M as the block 34 pivots in the direction shown by the arrow 32. It is transported to the transport area I through.

In the upstream conveyance area L, as shown in FIG. and a tension ring 58 coupled thereto that connects the container lid 38.
Rotation about the central axis of the container lid 34 is prevented, allowing stable transfer of the container lid 34.

When the container lid 38 and the tension ring 58 coupled thereto are transferred to the monitoring area K through the upstream conveying area L, the monitoring means 66 detects these and transfers the container lid 3 to the monitoring area K.
It is detected whether or not the tension ring 58 is coupled to 8. To explain with reference to FIG. 7, block 3
When the container lid 38 accommodated in the pocket 36 of No. 4 and coupled with the tension ring 58 is transferred as shown in FIG. The tension ring 58 coupled to the container lid 38 is sensed and the monitoring means 66 detects the tension ring 58 coupled to the container lid 38 . In such a case, no ringing signal is generated. On the other hand, when the container lid 38 with the tension ring 58 missing is accommodated in the pocket 36 and transferred, the first detection means 68 detects the container lid 38 but the second detection means 70 does not detect the tension ring 58. First, the monitoring means 66 is attached to the tension ring 58 on the container lid 38.
detect that they are not combined. In such a case, a no-ring signal is generated.

If the no-ring signal is not generated, the container lid 38 with which the tension ring 58 is connected is transferred through the exclusion zone J and the downstream conveying zone M to the transfer zone I where it is removed from the container lid transfer means 18. It is delivered to the bond reinforcing means 20 as required. In the downstream conveyance area M, similarly to the upstream conveyance area L, the tear-off tab piece 128 and the tension ring 58 coupled thereto are abutted and supported on the upper surface of the downstream stationary guide rail 46b, thereby removing the container lid. 38 and the tension ring 58 coupled thereto are prevented from pivoting about the central axis of the container lid 38.

On the other hand, if a no-ring signal is generated,
Based on this no-ring signal, the electromagnetic solenoid 96 of the removing means 82 is activated for a predetermined period of time. This predetermined period approximately corresponds to the time during which the pocket 36 provided in the block 34 moves within the exclusion zone J. When the electromagnetic solenoid 96 is energized, the first
The flow path is opened and compressed air from the air supply source is supplied as shown by arrow 124 (FIG. 5). Then, as the rotary conveyance plate 30 rotates, the exclusion zone J
The supply port of the second flow path corresponding to the pocket 36 located in the second channel (in which the container lid 38 without the tension ring 58 is housed) and the first
When the outlets of the channels are aligned, compressed air from a compressed air source (not shown) is removed through the first channel and the second channel, as seen in FIG. The container lid 38 (i.e., Norling container lid) fed into the pocket 36 in area J and thus accommodated in the pocket 36 resists the magnetic attraction force of the permanent magnet 44 by the action of compressed air. It is removed from the pocket 36 and collected and removed by the discharge sheet 60. As such, the knolling container lid 38 is reliably excluded in the exclusion zone J and is not transferred to the bond reinforcing means 20.

The safety switch 121 (FIG. 4) detects when the no-ring container lid 38 is not removed from the pocket 36 as required and jams at the opening of the ejection sheet 60. Stop the entire device.

<Effects of the Invention> As described above, in the apparatus of the present invention, since the container lid transfer means 18 is equipped with the monitoring means 66 and the removal means 88, the container lid 38 with the tension ring 58 missing is transferred. If this is the case, this is detected and the container lid 3 with this tension ring 58 missing is removed.
8 can be reliably eliminated without stopping the device, making it possible to improve the operating efficiency of the device.
