Description

[0001]
BACKGROUND OF THE INVENTION
After heating a tabbed cap comprising a top wall, a cylindrical skirt wall depending from the periphery of the top wall, and a tab including a base extending axially from a portion of the open end of the skirt wall With a tab, which is disposed downstream of the heating device for supplying and transporting the liner material to the inside of the top wall, and press-molding the liner material of the cap delivered from the heating device with a pressing tool The present invention relates to a cap liner molding apparatus.
[0002]
[Prior art]
The heating device described above has a first rotation having a rotating substrate and a plurality of semicircular arc-shaped notches which are fixed to the rotating substrate integrally with the rotating substrate and receive and convey the tab side of the skirt wall in the cap. It has a turret plate. The rotation of the first rotating turret plate allows each of the notches to sequentially pass through the cap delivery area. A liner mold pressing apparatus disposed on the downstream side of the heating device includes a rotating substrate and a rotating plate fixed on the rotating substrate and rotating integrally therewith. A gap for receiving the skirt wall of the cap is formed between the lower surface of the peripheral portion of the rotating plate and the corresponding upper surface of the peripheral portion of the rotating substrate. A plurality of semicircular cutouts for strippers are formed on the periphery of the rotating plate. Each of the notches is sequentially passed through the delivery area by rotation of the rotating plate, and is aligned with each of the notches of the first rotating turret plate in the delivery area.
[0003]
A plurality of embossing means are disposed above the peripheral edge of the rotating plate. Each of the stamping means includes a stamping tool, and each of the stamping tools includes a circular outer peripheral surface having a common vertical axis with each of the notches of the rotating plate. The inner peripheral edge of each notch of the rotating plate has a smaller diameter than the open end of the skirt wall and can be used as a stripper function to insert and remove the outer peripheral surface of the embossing tool. It is formed in the size which can accept.
[0004]
The cap in which the tab side of the skirt wall is received in the notch of the first rotating turret plate is aligned with the notch of the rotating plate in the cap delivery area. At this time, the embossing tool of the liner embossing apparatus is lowered and a part of the embossing tool is inserted into a part of the inner side of the open end of the skirt wall. Accompanying the further rotation of the rotating plate, the embossing tool descends to the inside of the top wall and presses the liner material already supplied in the heating device. Due to this forming action, the cap is held directly on the upper surface of the rotating substrate by the embossing tool. Thereafter, the cap is rotated and transferred while being pressed and held by the embossing tool. And the embossing tool is raised just before the discharge area. At that time, the cap is prevented from rising by the inner peripheral edge of the notch for the stripper of the rotating plate. A cap having a liner molded and mounted inside the top wall is discharged to the outside in the discharge area.
[0005]
[Problems to be solved by the invention]
In the conventional liner embossing apparatus, the cap that is conveyed by receiving the tab side of the skirt wall by the heating device is configured to be directly caught and held only by the descending embossing tool in the delivery area. It is extremely difficult to perform centering of the embossing tool and the cap as desired, and problems such as liner failure have occurred. This tendency becomes stronger as the rotation of the first rotating turret plate and the rotating plate becomes higher.
[0006]
In addition, the cap tends to rotate due to the presence of the tab in the process of being held by the embossing tool in the delivery area. However, since each notch of the rotating plate has a semicircular arc shape, the distance between both ends thereof is considerably wide. Therefore, the cap may rotate at a relatively large angle, and when the rotation occurs, the tab violently collides with the end of the notch of the rotating plate, or collides with the tab of another cap. The tab may be deformed. Such a defect tends to occur even after the embossing tool is lifted after the liner is molded and mounted. This tendency becomes stronger as the rotation of the first rotating turret plate and the rotating plate becomes higher.
[0007]
It is an object of the present invention to reliably perform centering of an embossing tool and a cap as desired when receiving a tabbed cap from a heating device, and to provide predetermined rotation of the cap during and after the cap is received. The present invention provides a novel tab-cap type liner embossing apparatus that can be controlled within the above range and that has a very simple structure.
[0008]
[Means for Solving the Problems]
According to the present invention, in a cap comprising a top wall, a cylindrical skirt wall depending from the periphery of the top wall, and a tab including a base portion extending in the axial direction from a part of the open end of the skirt wall. A first rotating turret plate having a plurality of notches at the periphery for receiving and transporting the tab side of the skirt wall, and each of the notches sequentially moves a delivery area of the cap by rotation of the rotating turret plate; In the liner embossing device of the tabbed cap disposed on the downstream side of the heating device passed through,
A second rotating turret plate having a rotating substrate and a plurality of semicircular arc-shaped notches which are fixed on the rotating substrate and receive and convey the opposite side of the tab of the skirt wall, Each of the notches by rotation is sequentially passed through the delivery area, and a second rotating turret plate that aligns with each of the notches of the first rotating turret plate in the delivery area, and the second A rotating plate fixed on the rotating turret plate and having a peripheral edge larger in diameter than the second rotating turret plate; and disposed above the peripheral portion of the rotating plate, and the cut of the second rotating turret plate. A plurality of embossing means comprising a embossing tool having a circular outer peripheral surface having a common vertical axis with each of the notches,
A plurality of notch means are formed at the periphery of the rotating plate, each notch means having a common vertical axis for each notch of the second rotating turret plate and An arc-shaped notch for a stripper having a large arc length, and a V-shaped notch comprising a pair of inclined portions with a circumferential interval extending from both ends of the arc-shaped notch toward the periphery,
The pair of inclined portions are provided at a height position that is positioned at a distance from both sides in the circumferential direction of the tab of the cap that is received by the second rotating turret plate and that contacts the tab. A tabbed cap liner embossing device is provided.
[0009]
In the liner stamping apparatus according to the present invention, a plurality of semicircular arc-shaped notches for receiving and transporting the opposite side of the tab of the skirt wall are provided at the periphery below the rotating plate fixed on the rotating substrate. A second rotating turret plate is fixed. Each of the cutouts of the second rotating turret plate is sequentially passed through the delivery area by its rotation and is aligned with each of the cutouts of the first rotating turret plate in the delivery area. Therefore, the cap that is received by the notch of the first rotating turret plate of the heating device and the tab side of the skirt wall is received and conveyed in the notch of the second rotating turret plate of the liner stamping apparatus in the delivery area. The opposite side of the skirt wall tab is accepted. That is, in the delivery area, the substantially semicircular circumference on the tab side of the cap skirt wall is received in the notch of the first rotating turret plate, and the substantially semicircular circumference on the opposite side of the tab is the notch of the second rotating turret plate. The cap is positioned in such a manner that its vertical axis is generally aligned with the notch of the second rotating turret plate and the common vertical axis of the embossing tool. As a result, centering of the embossing tool and the cap, which has been difficult in the past, is reliably performed as desired in the delivery area, and occurrence of problems such as defective liners is prevented.
[0010]
Also, in the liner stamping apparatus according to the present invention, a pair of inclined portions of the V-shaped notch of the rotating plate is positioned on both sides of the tab with an interval between them, and these inclined portions are formed on the second rotating turret plate. The notch is formed so as to extend from both ends of the notch forming an arc longer than the notch semicircular arc toward the periphery, and the distance between both ends is smaller than both ends of the conventional semicircular arc. Therefore, when the cap transferred by receiving the tab side of the skirt wall by the heating device is received in the notch of the second rotating turret plate of the liner stamping apparatus, the opposite side of the tab of the skirt wall is received in the delivery area. Even if the cap is rotated, the pair of inclined portions restricts the rotational movement of the tab to a predetermined range that is significantly smaller than the conventional one, so that the deformation of the tab is reliably prevented.
[0011]
It goes without saying that the action and effect of restricting the rotational movement of the tab are continuously held even after the embossing tool is raised after the liner is molded and fixed. Due to the respective effects of the centering of the embossing tool and the cap and the rotational movement restriction of the tab according to the present invention, it is possible to further increase the cap conveyance speed and to significantly improve the productivity of the cap. This can be said to be able to convey (deliver) smoothly and surely at a relatively high speed even when the direction of the tab of the cap is reversed in the delivery from the heating device to the liner embossing device. .
[0012]
Each of the arc-shaped notches has a stripper function, and each of the V-shaped notches has a function of restricting the rotation of the tab as described above, and each of these notches is rotated. Since it is formed at the peripheral edge of the plate, the structure is remarkably simple and can be put into practical use at low cost.
[0013]
The shape of the pair of inclined portions at each of the V-shaped notches of the turntable spreads within a predetermined range when the cap is delivered, so that the second from the first rotary turret plate is allowed. It is easy to receive the cap into the rotating turret plate.
[0014]

The cap 100 delivered from the delivery area R1 is conveyed by the first rotating turret plate 20 with the tab 108 directed inward in the radial direction, and heated by the high frequency heating device between the position X and the position Y. Then, the liner material is supplied to the inside of the top wall 102 between the position Y and the position Z. And it is delivered to the liner stamping apparatus 10 in the delivery area R2.
[0020]
Next, the liner stamping apparatus 2 configured according to the present invention will be described. 1 to 5, reference numeral 30 denotes a rotating substrate, which is rotatably supported on a fixed shaft (not shown) that stands upright on a stationary substrate (not shown). The rotating substrate 30 has an upper surface 32 that supports the top wall 102 of the cap 100 to be transported, and has a function of receiving on the lower side at the time of liner mold pressing, which will be described later. It is formed from a disk member.
[0021]
Referring also to FIG. 6, reference numeral 40 denotes a second rotating turret plate, which is fixed on the rotating substrate 30. In this embodiment, the second rotating turret plate 40 is formed of a single ring-shaped plate member, and a plurality of the rotative turret plates 40 that receive and convey the opposite side of the tab 108 of the skirt wall 104 are provided on the periphery thereof. A semicircular cutout 42 is formed. The second rotating turret plate 40 may be configured by fixing a plurality of divided (for example, two) arc-shaped plate members on the rotating substrate 30 in a ring shape. Due to the rotation of the rotating substrate 30, and thus the second rotating turret plate 40, in the clockwise direction in FIG. 1, each of the notches 42 is rotated and transferred sequentially through the delivery area R2 and the discharge area R3. Each of the notches 42 of the second rotating turret plate 40 is aligned with each of the notches 22 of the first rotating turret plate 20 in the delivery area R2. In the delivery area R2, approximately half of the circumference of the skirt wall 104 of the cap 100 is received by the notch 22 of the first rotating turret plate 20, and the other approximately half is notched 42 of the second rotating turret plate 40. To be accepted.
[0022]
The height (thickness) of the second rotating turret plate 40 from the upper surface 32 of the rotating substrate 30 is defined to be slightly higher than the height (axial length) of the skirt wall 104. The peripheral portion of the second rotating turret plate 40 extending from the outer peripheral edge of the second rotating turret plate 40 beyond the deepest portion of each of the notches 42 to the inside in the radial direction is opposed to the lower surface 44 of the peripheral portion. The thickness is defined such that a predetermined gap S is formed between the rotating substrate 30 and the upper surface 32 of the rotating substrate 30. In this embodiment, the thickness is defined by forming an annular thin portion on the outer peripheral edge of the second rotating turret plate 40 (number 46 indicates the step portion).
[0023]
Referring also to FIG. 7, reference numeral 50 denotes a rotating plate, which is fixed on the second rotating turret plate 40. The rotating plate 50 is formed from a single ring-shaped plate member, like the second rotating turret plate 40, and has a peripheral edge 52 having a diameter larger than that of the second rotating turret plate 40. Similar to the second rotating turret plate 40, the rotating plate 50 can be composed of a plurality of divided arc-shaped plate members. A plurality of notch means are formed on the peripheral edge 52 of the rotating plate 50. Each of these notch means comprises an arc-shaped notch 54 for a stripper and a V-shaped notch 56 formed continuously on the peripheral edge 52 side.
[0024]
Each of the arc-shaped notches 54 is positioned to have a common vertical axis with respect to the corresponding notch 42 of the second rotating turret plate 40. The length of each arc of the arc-shaped notch 54 is formed longer than the length (substantially semicircle) of each arc of the notch 42 of the second rotating turret plate 40. Each of the V-shaped notches 56 includes a pair of inclined portions 56a and 56b whose circumferential intervals widen from the both ends of each arc-shaped notch 54 toward the peripheral edge 52 (become widened toward the end). The inclined portions 56a and 56b are positioned at both sides thereof so as to restrict the rotational movement of the tab 108 of the cap 100 received by the second rotating turret plate 40. The inner peripheral edge of each arc-shaped notch 54 of the rotating plate 50 is more than the inner peripheral edge of each notch 42 of the second rotating turret plate 40 so as to prevent the upward movement of the open end of the skirt wall 104. It has a slightly smaller diameter. With this configuration, each of the arc-shaped notches 54 functions as a stripper.
[0025]
Above the peripheral edge of the rotating plate 50, the stamping means 60 known per se corresponds to each of the notches 42 of the second rotating turret plate 40 and each of the arc-shaped notches 54 of the rotating plate 50. Are disposed at intervals in the circumferential direction. Each of the stamping means 60 includes a stamping tool 62. Each of the embossing tools 62 has a circular outer peripheral surface having a common vertical axis with each of the notches 54 of the second rotating turret plate 50. Each embossing tool 62 therefore has a common vertical axis with each of the arcuate notches 54 of the rotating plate 50. The inner peripheral edge of each arc-shaped notch 54 of the rotating plate 50 is formed to a size that allows the insertion and removal of the outer peripheral surface of the corresponding embossing tool 62.
[0026]
As described above, the stationary support plate 24 of the heating device 4 is configured to extend from the delivery region R1 to a position close to the rotary substrate 30 of the liner mold pressing device 2. The upper surface 25 of the stationary support plate 24 is defined to be substantially flush with the upper surface 32 of the rotating substrate 30. The stationary outer guide plate 26 of the heating device 4 extends from the delivery area R1 to a position close to the liner mold pressing apparatus 2, and further in the delivery area R2, the second rotating turret plate 40 of the liner mold pressing apparatus 2 is used. It extends so that it may be located in the clearance gap S between the lower surface 44 of the peripheral part of this, and the upper surface 32 of the rotating substrate 30. FIG. The inner peripheral surface 27 of the stationary outer guide plate 26 is positioned close to the opposite side of the tab 108 on the skirt wall 104 of the cap 100 in the delivery region R2. On the other hand, although not shown, the stationary upper guide plate 28 of the heating device 4 extends from the delivery area R1 to a position close to the peripheral edge 52 of the rotating plate 50. With the above configuration, the cap 100 is smoothly and reliably transported from the heating device 4 to the liner mold pressing device 2.
[0027]
Next, the operation of the liner embossing device 2 for the tabbed cap of the present invention configured as described above will be described. Although not shown, the rotary substrate 30 (and the second rotary turret plate 40 and the rotary plate 50) of the liner stamping apparatus 2, the first rotary turret plate 20 and the reversing device 8 of the heating device 4 are used. Each of the rotating turret plates 10 is drivingly coupled to a common electric motor via a gear device, and is configured to be driven to rotate at the same peripheral speed in synchronization with the direction shown in FIG.
[0028]
The cap 100 that is received by the notch 22 of the first rotating turret plate 20 of the heating device 4 and transported with the tab 108 side of the skirt wall 104 is transported in the second region of the liner stamping device 2 in the delivery area R2. The opposite side of the tab 108 of the skirt wall 104 is received in the notch 42 of the rotating turret plate 40. That is, in the delivery area R2, the substantially semicircular circumference on the tab 108 side of the skirt wall 104 of the cap 100 is received by the notch 22 of the first rotating turret plate 20, and the substantially semicircular circumference on the opposite side of the tab 108 is the second semicircular circumference. Therefore, the vertical axis of the cap 100 is substantially aligned with the common vertical axis of the notch 42 of the second rotating turret plate 40 and the embossing tool 62. Positioned in form. As a result, centering of the embossing tool 62 and the cap 100, which has been difficult in the past, is reliably performed as desired in the delivery area R2, and the occurrence of problems such as defective liners is prevented.
[0029]
Further, on both sides of the tab 108 of the cap 100, a pair of inclined portions 56a and 56b of the V-shaped notch 56 of the rotating plate 50 are positioned at an interval, and these inclined portions 56a and 56b are arranged in the second rotation. Since it is configured to extend from both ends of the notch 54 that forms an arc longer than the semicircular arc of the notch 42 of the turret plate 40 toward the periphery, the interval between the both ends is smaller than both ends of the conventional semicircular arc. Therefore, the cap 100 received and conveyed on the tab 108 side of the skirt wall 104 by the heating device 4 is transferred to the notch 42 of the second rotary turret plate 40 of the liner stamping apparatus 2 in the delivery area R2. Even if rotation occurs when the opposite side of the tab 108 of the 104 is received, the rotational movement of the tab 108 is remarkably restricted as compared with the prior art.
[0030]
In the delivery area R <b> 2, the stamping tool 62 of the corresponding stamping means 60 descends and a part of its tip penetrates the notch 54 of the rotating plate 50 and the notch 42 of the second rotating turret plate 40. Then, it is inserted into a part of the inside of the open end of the skirt wall 102 (see FIG. 4). As a result, the movement of the cap 100 outward in the radial direction of the second rotating turret plate 40 is prevented. Along with the further rotation of the rotary substrate 30, the embossing tool 62 descends to the inside of the top wall 102 and presses a liner material (not shown). Thereafter, the cap 100 is rotationally transferred in a state where the opposite side of the tab 108 of the skirt wall 104 is received in the notch 42 of the second rotating turret plate 40 and pressed by the embossing tool 62. The embossing tool 62 is raised before the discharge area R3 of the liner embossing device 2. At that time, the cap 100 is prevented from rising by the inner peripheral edge of the notch 54 of the rotating plate 50, which is a stripper. The cap 100 in which the liner is molded and attached to the inside of the top wall 102 is discharged to the outside in the discharge area R2.
[0031]
Although the present invention has been described in detail based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications or corrections can be made within the scope of the present invention.
[0032]
【The invention's effect】
According to the present invention, when the tabbed cap is received from the heating device in the delivery area, the centering of the embossing tool and the cap, which has been difficult in the past, is desired due to the cooperative operation of the first and second rotating turret plates. It is executed as expected, and the occurrence of defects such as liner failure is prevented. Further, even when the cap is received in the delivery area and after the cap is received, the movement in the rotation direction of the tab can be restricted to a predetermined range by the V-shaped notch formed in the rotating plate, and therefore the rotation of the cap is controlled to a predetermined range. The range can be regulated. Further, since the arc-shaped notch having the function of the stripper and the V-shaped notch are formed on the periphery of the common rotating plate, the structure is very simple and can be easily put into practical use at low cost. .
