Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for holding and processing continuously supplied elongated objects at regular intervals, and more specifically, for forming a belt-like sheet into a cylindrical shape, Fill the cylinder with the internal solution,
Furthermore, in the process of separating and shaping each packaging container, the above-mentioned band-like sheets and The present invention relates to a device that holds and processes elongated bodies such as cylindrical bodies at regular intervals.

[Prior Art] In an apparatus for obtaining each packaging container filled with contents from a strip sheet on which a pattern of a developed view of the packaging container, etc. is continuously printed, a crease line stamping process for shaping each packaging container, A vertical sealing process to form a tube, a process of filling the tube with contents, a horizontal sealing process of dividing the filled tube into each packaging container, a process of cutting the horizontal seal, and a process of shaping into a hexahedral container. There is.

Conventionally, as a horizontal sealing mechanism for horizontally sealing a tube body, a rotating disk that is continuously driven to rotate,
A plurality of clamping mold bodies are provided at equal intervals in the circumferential direction of the rotating disk, each having an upper mold located inside the rotating disc in the radial direction and a lower mold located outside the rotating disc, It is known that a tube body that is continuously fed between the upper and lower molds is sandwiched between the upper mold and the lower mold to perform a horizontal seal (Japanese Patent Application Laid-open No. 48903/1983).

The horizontal seal mechanism moves each clamping mold body in the radial direction of the rotating disk to change the circumferential spacing of each clamping mold body, thereby changing the length of the container partitioned by the horizontal seal. Equipped with a horizontal seal position adjustment mechanism to change the position of the seal.

Note that the crease line stamping process and the horizontal sealing process need to be done in a predetermined position according to the sheet pattern, and both processes are performed while holding the sheet or tube body, so the shape of the formwork to be held is The only difference is the shape etc. Therefore, both processes basically have the same configuration.

[Problems to be Solved by the Invention] The horizontal seal position adjustment mechanism described above is provided for the purpose of moving each clamping mold body in the radial direction of the rotating disk according to the length of the container when the horizontal seal mechanism stops operating. Therefore, it was not possible to change the circumferential spacing between the clamping bodies during operation of the lateral seal mechanism.

Therefore, even if a printing pattern misalignment occurs due to transfer misalignment of the elongated object or thermal expansion or contraction of the elongated object during operation of the horizontal sealing mechanism, the elongated elongation by the individual clamping bodies can be adjusted to accommodate the misalignment. Since it is not possible to change the location at which the elongated object is held, it is not possible to apply a horizontal seal at an accurate position to match the pattern of the elongated object or to engrave a crease line.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention includes a rotating disk that is continuously driven to rotate, and a plurality of rotating disks provided at equal intervals in the circumferential direction of the rotating disk. A clamping mold body having an upper mold located on the inside in the radial direction of the disk and a lower mold located on the outside, and a long body continuously supplied between the upper mold and the lower mold is placed on top of the holding mold. In a device that clamps and processes continuously supplied long objects at regular intervals between a mold and a lower mold, each clamping mold is provided for each clamping mold body, and each clamping mold is A cam stopper that displaces the body in the radial direction of the rotating disk, a cam follower that rotates the cam stopper in conjunction with the cam stopper, and the cam follower that is provided outside the rotating disk and is moved as the rotating disk rotates. a rocking plate that engages with the cam follower and displaces the cam follower in the radial direction of the rotating disk to rotate the cam stopper; The cam stopper is provided with a drive means for adjusting the amount of displacement and the amount of rotation of the cam stopper.

[Operation] According to the above configuration, by moving the swing plate in the radial direction of the rotating disk by the driving means, the cam follower, which is transferred as the rotating disk rotates, is engaged with the swing plate. At the same time, the cam follower can be displaced in the radial direction of the rotating disk. By displacing the cam follower in the radial direction of the rotating disk, the cam stopper linked to the cam follower can be rotated, and each clamping body can be displaced in the radial direction of the rotating disk by rotation of the cam stopper. .

By displacing each clamping mold body radially inward of the rotating disk, the circumferential interval between the clamping mold bodies can be narrowed, and each clamping mold body can be moved radially outward of the rotating disk. By displacing the clamping mold bodies to , it is possible to increase the circumferential spacing between the clamping mold bodies.

Therefore, during the rotation of the rotating disk, if there is a misalignment between the printed pattern and the clamping location due to misalignment of the elongated body during transportation or thermal expansion or contraction of the elongated body, the printing pattern will be adjusted according to the amount of misalignment. By moving the rocking plate in and out of the rotating disk in the radial direction, the displacement can be eliminated.

[Example] An example of the present invention will be described using a horizontal seal mechanism. The rotating disc 1 is provided with clamping mold bodies 2, 2, . The upper mold 3 is received and positioned by the upper mold 3.

The cam stopper 5 is rotatably supported by the rotary disk 1, and a cam follower 7' provided on a fixed rod 7 of the shaft 6 is controlled to engage with the rocking plate 3, so that the shaft 6 is rotated by the rocking of the rocking plate 8. rotates, and the receiving part of the upper die 3 of the cam stopper 5 changes, so the distance of the upper die 3 from the center point of the rotating disk 1 changes, and the upper die 3 rotates in a circular orbit with a set radius. .

Therefore, the cylinder 9 that regulates the rocking of the rocking plate 3 is electrically controlled by detecting the pattern of the elongated body 17 (filled with contents to form a tube body) sent to the horizontal sealing mechanism. By doing so, the upper mold 3 can be brought into contact with a predetermined location.

Further, the lower mold 10 which separates from the upper mold 3 to sandwich the elongated body 17 to form a lateral seal has one end rotatably pivoted to the upper mold 3 and is driven by the rotating disc 1 together with the upper mold 3. and makes a rotational movement.

The trochanter 12 provided on the lower mold 10 is engaged with a twisting guide groove 13 that constantly rolls and slides as the lower mold 10 rotates, and the twisted portions 13a are separated from the upper mold 3. The portion between the non-twisted portions 13b comes into contact with the upper die 3.

Further, a pressing circular arc plate 14 is installed outside the lower mold 10 between the non-twisted portions 13b, and is in rolling contact with a pressing roller 16 provided with a spring 15 interposed below the contact with the upper mold 3. Since the lower mold 10 is pressed against the upper mold 3 by the elastic force of the spring 15, the pressing force can be applied without being affected by the positional fluctuation in the inner and outer directions due to the rotation of the cam stopper 5 of the upper mold 3.

Therefore, the upper die 3 and the lower die 10, which are freely positioned in the inner and outer directions of the rotary disk 1 by the cam stopper 5, rotate, and the lower die 10 rotates while the torsion guide groove on which the trochanter 12 slides is formed. 13, rotates and separates from the upper mold 3.

When the upper and lower dies 3 and 10 are brought into contact, the arc plate 14 for pinching applies pressure, and since the position of the upper die 3 can be varied by the cam stopper 5, the contact is made according to the pattern position of the elongated body 17 to be pressed. It is possible to clamp a predetermined location by changing the grounding point, and since it follows the elongated body while clamping, horizontal sealing can be performed continuously.

[Effects of the Invention] According to the present invention, a fold line can be embossed or a horizontal seal can be engraved at an accurate position according to a pre-printed pattern on a long sheet, and the sheet can be continuously transported. Since stamping and sealing can be performed according to the transfer speed without stopping, it is possible to achieve a marked increase in efficiency compared to conventional work.
