The cup 2 supplied by the cup supply mechanism 6 is provided with a flange at the opening at the upper end, and the flange is engaged with the peripheral edge of the hole of the plate 20 and held.
[0019]
On the downstream side of the cup supply mechanism 6, a filling mechanism 8 for filling the contents such as liquid into the cup 2 is provided. Below the position where the filling mechanism 8 is provided, the cup 2 conveyed intermittently by the container conveyance conveyor 4 is temporarily stopped to perform filling.
[0020]
A sealing mechanism 10 and a cutting mechanism 12 are provided in order at a predetermined interval downstream of the filling mechanism 8. Between the filling mechanism 8 and the sealing mechanism 10, a film sheet 24 is supplied from above by a film supply mechanism (indicated by reference numeral 22), which will be described later. The upper direction is changed toward the downstream side (left side in FIG. 1), and is sent between the upper sealing mechanism 10 and the cutting mechanism 12 and the upper surface of the cup 2 conveyed by the lower conveyor 4. . After the film sheet 24 is thermocompression-bonded to the opening of the cup 2 by the seal mechanism 10 at the stop position of the cup 2, the periphery of a portion serving as the lid of the cup 2 is punched by the cutting mechanism 12.
[0021]
Next, the structure of the film supply mechanism 22 will be described with reference to FIGS. 1 and 2 and FIGS. A supply stand (film roll support means) 26 of the film supply mechanism 22 is installed adjacent to the side of the machine frame 13 where the main body of the filling and sealing device is provided (see FIG. 2). On the supply stand 26, a film roll 24A on which the film sheet 24 is wound in a roll shape is supported. The film sheet 24 pulled out from the film roll 24A is sent through a plurality of rollers 28 supported by a supply stand 26. In addition, as the film sheet 24 used as a lid of the cup 2, a film made of aluminum or resin, or a film coated with these, is generally used.
[0022]
The film supply stand 26 is provided with a dancer roller 30 for adjusting the tension of the film sheet 24 to be sent out. The film sheet 24 is sent upward through the dancer roller 30 and installed in the machine frame 13. Is supplied to the main body of the filling and sealing device.
[0023]
Around the position where the seal mechanism 10 and the cutting mechanism 12 are provided above the side frame 13a of the machine frame 13, in a direction parallel to the container transport direction by the transport conveyor 4 (see the arrow A in FIGS. 1 and 3). The installed introduction roller 32 (see FIGS. 2 and 3) is attached, and the film sheet 24 sent via the dancer roller 30 is moved by the introduction roller 32 installed in parallel with the container conveyance direction A. It is supplied into the main body of the filling and sealing device in a direction orthogonal to the container transport direction A.
[0024]
A direction changing roller 34 is attached at an angle of approximately 45 degrees between both side frames 13a and 13b of the machine frame 13 arranged in parallel on both sides of the container conveying path of the container conveying conveyor 4. The direction conversion roller 34 has an end 34a located on the downstream side thereof rotatably connected to a fulcrum pin 36 on the frame 13a side to which the introduction roller 32 is attached. The swinging end 34b of the direction changing roller 34 is arranged facing the upstream side of the conveyor 4 and is connected to a rod of a servo cylinder 38 as an angle changing mechanism. Is moved, the angle of the direction changing roller 34 can be changed.
[0025]
The servo cylinder 38 includes a screw shaft (rod) and a nut screwed onto the screw shaft. The nut is rotated by a servomotor to move the screw shaft forward and backward. The tip 38a of the screw shaft is connected to the swinging end 34b of the direction changing roller 34. A long hole 34c is formed at the swinging end 34b of the direction changing roller 34, and the pin 40 of the cylinder rod tip 38a fits into the long hole 34c so as to be relatively movable.
[0026]
The film sheet 24 fed into the filling and sealing device via the introduction roller 32 installed in parallel with the conveyance direction A of the cup 2 is changed in direction by almost 90 degrees by the direction change roller 34, and is upstream of the conveyance conveyor 4. Turned to the side. On the upstream side of the direction changing roller 34, an upper roller 42 is installed orthogonal to the transport direction A of the transport conveyor 4. The upper sheet 42 changes the direction of the film sheet 24 whose feed direction is changed by 90 degrees by the direction changing roller 34 in a substantially downward direction. Further, a lower roller 44 is disposed below the upper roller 42 and slightly above the transport surface of the transport conveyor 4, and the film sheet 24 sent downward from above is transported by the lower roller 44. 4 can be changed substantially horizontally toward the downstream side in the transport direction. In FIG. 5, the lower roller 44 is composed of two rollers.
[0027]
The film sheet 24 directed to the downstream side of the conveyor 4 and supplied in a substantially horizontal state is provided at the opening of the cup 2 which is conveyed on the container conveyor 4 and temporarily stopped at this position by the sealing mechanism 10. Thermocompression bonded to the flange. Subsequently, in the next cutting mechanism 12, the periphery of a portion that is attached to the mouth of the cup 2 of the film sheet 24 and serves as a lid is cut. The remaining portion 24a (see FIG. 1) of the film sheet 24 from which the lid is cut out is taken up by a take-up roll 48 via a roller 46.
[0028]
A drive roller 50 is provided between the upper roller 42 and the lower roller 44. After the film sheet 24 is adhered to the flange at the mouth of the container 4 in the sealing mechanism 10, the film sheet 24 advances with the cup 2 conveyed by the traveling conveyor 4, but is not pulled by the movement of the cup 2. In addition, the rotation of the drive roller 50 allows the sheet to be fed synchronously so as to follow the movement of the cup 2.
[0029]
Free rollers 52 and 54 are arranged above and below the driving roller 50, and the film sheet 24 sent downward from the upper roller 42 is first wound around the lower free roller 54 and then wound around the driving roller 50. By turning, the contact area with the drive roller 52 is increased. Then, the drive roller 50 is pressed by the free roller 52 from above. The drive roller 50 is rotationally driven by a servomotor 56 (see FIGS. 4 and 5) in synchronization with the movement of the container transport conveyor 4.
[0030]
A mark sensor 58 that detects marks printed on the film sheet 24 at a predetermined pitch is provided toward the surface of the drive roller 50 (see FIG. 5). As described above, the drive roller 50 is operated by the servo motor 56 in synchronization with the movement of the transport conveyor 4, but the feed amount of the film sheet 24 depends on the detection result of the mark position by the mark sensor 58. Is increased or decreased.
[0031]
A feed roller 62 driven by a motor 60 is provided in front of the dancer roller 30 so that the film sheet 24 is pulled out from the film roll 24A and sent to the dancer roller 30. The feed roller 62 is stopped when the dancer roller 30 descends to the lower end, and is driven at a higher speed than the drive roller 50 when a predetermined time (for example, 3 seconds) elapses from the lower end. As a result, the dancer roller 30 repeatedly moves up and down. By providing the dancer roller 30 in this manner, a constant tension can be applied to the film sheet 24 without synchronizing the feed roller 62 and the drive roller 50. When the dancer roller 30 has risen to the rising end, the present device stops. The lower end and the upper end of the dancer roller 30 are detected by a lower limit sensor 64 and an upper limit sensor 66, respectively. A pressing roller 68 for pressing the film sheet 24 against the feed roller 62 is provided above the feed roller 62.
[0032]
Further, a pair of end sensors 70 for detecting the positions of both end portions of the film sheet 24 are provided between the upper roller 42 and the driving roller 50. The meandering amount of the film sheet 24 is detected by these end sensors 70, and the angle of the direction changing roller 34 is adjusted according to the meandering amount. Here, a state in which the position of the film sheet 24 is changed by adjusting the angle of the direction changing roller 34 will be described with reference to FIG. 3 in which the direction changing roller 34 and the film sheet 24 are viewed from above. When the rod of the servo cylinder 38 extends and the swinging end 34b moves upstream in the transport direction A, the film sheet 24 is displaced upward in FIG. 3, and conversely, the rod of the servo cylinder 38 contracts. When the swinging end moves to the downstream side in the transport direction A, the position of the film sheet 24 is shifted downward in FIG. Note that the end sensor 70 does not necessarily need to be provided corresponding to both ends of the film sheet 24, and only one may be provided. When only one end sensor 70 is provided in this manner, it is preferable to provide the end sensor 70 on the side closer to the direction changing roller 34 (the lower side in FIG. 3) because the response to the change in the angle of the direction changing roller 34 is fast.
[0033]
The operation of the filling and sealing device according to the above configuration will be described. A cup supply mechanism 6 is provided above the upstream end of the container conveyor 4, and the cup supply mechanism 6 inserts a cup into each container support hole of the plate 20 attached between the chains 18 on both sides of the conveyor 4. 2 are supplied. The cup 2 has a flange formed at the upper end opening, and the flange engages around the hole of the plate 20 and is conveyed in a suspended state.
[0034]
The transport conveyor 4 intermittently transports the cup 2 by repeating running and stopping, and the transported cup 2 is filled in the container transport path in the downstream of the cup supply mechanism 6 in order. It stops at the position of the mechanism 8, the seal mechanism 10, and the cutting mechanism 12. The cup 2 first stops below the filling mechanism 8 and is filled with contents such as liquid. The cup 2 filled with the contents is conveyed by the conveyor 4 below the next seal mechanism 10.
[0035]
On the other hand, the film sheet 24 serving as a lid of the cup 2 is pulled out from a film roll 24A supported at a lower portion of the film supply stand 26, wound around a feed roller 62 via a plurality of rollers 28, and It is sent out by 62 and sent to the dancer roller 30. The dancer roller 30 repeatedly moves up and down to adjust the tension of the film sheet 24. When the dancer roller 30 descends to the lowest position, the lower limit sensor 64 detects this and stops driving the feed roller 62. Further, after a certain time (for example, 3 seconds) elapses from the lower end, the drive roller 50 is driven at a feed speed higher than that of the downstream drive roller 50. In this embodiment, another auxiliary roll 24B is supported above the film roll 24A of the film supply stand 26, and when the film roll 24A runs out, it is replaced by the auxiliary roll 24B and the film sheet 24 is replaced. Continue to supply. When the film roll 24A in use approaches the end of the spare roll 24B, the spare roll 24B is connected to the starting end of the film roll 24A for replacement. The connection and replacement of the film rolls 24A and 24B may be performed manually, or may be automated by a conventionally known technique. In particular, in this embodiment, since the film roll 24A is disposed on the side of the conveyor 4, the replacement operation is extremely easy.
[0036]
The film sheet 24 sent upward through the dancer roller 30 is sent into the machine frame 13 through the introduction roller 32, is wound around the direction changing roller 34, is changed in the direction by 90 degrees, and is transferred in a horizontal state. 4 upstream. The film sheet 24 is further turned in the vertical direction from the horizontal state by the upper roller 42 and is sent toward the lower conveyor 4.
[0037]
A pair of end sensors 70 are provided below the upper roller 42, and detect the positions of both ends of the film sheet 24 whose direction is changed from the horizontal direction to the vertical direction. The servo cylinder 38 is operated in accordance with the positions of both ends of the film sheet 24 detected by the end sensors 70 to change the angle of the direction changing roller 34, thereby correcting the meandering of the film sheet 24. The film sheet 24 has a slight thickness variation due to coating unevenness or the like, and is always meandering. However, the end sensor 70 always detects the end position and adjusts the angle of the direction changing roller 34. Thereby, the meandering correction can be performed with high accuracy. The end sensor 70 may be provided at another position. For example, when the end sensor 70 is provided between the direction changing roller 34 and the upper roller 42, the film sheet 24 is changed by changing the angle of the direction changing roller 34. May be deflected, so that it is difficult to detect accurately. In addition, when the film sheet 24 is provided on the driving roller 50, the detection result may not be reflected because the film sheet 24 is sandwiched and fed. As in the embodiment, it is preferably provided at a position between the upper roller 42 and the driving roller 50.
[0038]
The film sheet 24 sent downward is wound around the drive roller 50 after being wrapped around the free roller 54 below the drive roller 50, and is supplied toward the lower conveyor 4 by the drive of the drive roller 50. You. At this time, the film sheet 24 is pressed against the drive roller 50 by the upper free roller 52.
[0039]
A lower roller 44 is provided below the driving roller 50, and the film sheet 24 sent vertically downward from the upper roller 42 and the driving roller 50 is moved horizontally by the lower roller 44. The direction is changed and the sheet is sent toward the downstream side of the conveyor 4. A seal mechanism 10 is provided downstream of the lower roller 44, and the film sheet 24 is thermocompression-bonded to a flange at an opening of the cup 2.
[0040]
The film sheet 24 adhered to the opening of the cup 2 accommodated in the plate 20 of the conveyor 4 advances integrally with the cup 2 conveyed by the conveyor 4, but is not pulled by the cup 2. As described above, the sheet is fed by the driving roller 50 in synchronization with the movement of the cup 2. In the next cutting mechanism 12, the periphery of a portion of the film sheet 24 attached to the upper surface of the cup 2 serving as the lid of the cup 2 is cut. The cup 2 sealed by the lid made of the cut-off film is transported by the transport conveyor 4 as it is, taken out downstream, and sent to the next step. On the other hand, the remaining portion 24 a from which the lid portion of the film sheet 24 is cut out is taken up by a take-up roll 48 via a roller 46.
[0041]
In this embodiment, the film rolls 24A and 24B are installed outside the filling and sealing device, and are not installed above the cup 2 before being sealed after the contents are filled. There is no risk that foreign matter such as dust generated when the sheet is pulled out of the cups 24A and 24B will enter the filled cup 2. In particular, the direction changing roller 34 is arranged at a position above or downstream of the sealing mechanism 10, and since the opening of the conveyed cup 2 is already covered with the film sheet 24, the direction changing roller 34 is Even if dust is generated when the film sheet 24 is rubbed against 34, there is no possibility of falling into the cup 2. Further, since the film rolls 24A and 24B are installed at a low position, the exchange of the film rolls 24A and 24B is easy, and the maintainability is improved. Further, since the film rolls 24A and 24B and the dancer roller 30 are installed at low positions, the height of the entire apparatus does not increase, and the film sheet 24 is supplied from the lateral direction of the filling and sealing apparatus. Therefore, the overall length of the apparatus does not increase.
[0042]
In the above-described embodiment, a plurality of independent cups 2 made of paper or resin (for example, cups used as containers for yogurt, pudding, jelly, etc.) are transferred from the cup supply mechanism 6 to the conveyor 4. Although it is designed to be supplied, it is not limited to such an independent cup 2, but a plurality of continuous containers formed by depressing a resin film (for example, a container such as a yogurt that can be divided along a perforation). ) Can also be applied.
[0043]
【The invention's effect】
As described above, according to the first aspect of the invention, there is obtained an effect that the film roll can be easily replaced and the maintenance property is excellent. Further, there is no possibility that foreign matter such as dust from the film roll falls into the container after filling and before sealing.
[0044]
According to the second aspect of the invention, meandering during the supply of the film sheet can be corrected.
[0045]
Further, according to the third aspect of the present invention, the end of the film sheet is detected by the detecting means, so that the meandering of the film sheet can be corrected with high accuracy.
