It is done.
[0024]
Next, the configuration of the first container reversing wheel 20 and the second container reversing wheel 38 will be described with reference to FIGS. Since both the reversing wheels 20 and 38 have the same configuration, only the configuration of the first reversing wheel 20 will be described and the description of the second reversing wheel 38 will be omitted. The first reversing wheel 20 is provided with a plurality of container gripping means 21 on the outer periphery of a rotating body 48 (the whole is not shown). In this embodiment, mounting blocks 50 having a U-shaped cross section are fixed horizontally on the outer periphery of the rotating body 48 at equal intervals in the circumferential direction with the openings 50a facing outward in the radial direction. The container gripping means 21 is attached to each block 50. In this embodiment, each of these container gripping means has two container gripping portions 52.
[0025]
Two parallel leaf springs (support plates) 56 whose center portions are fixed to both ends of the rod 54 are rotatably supported in the opening 50 a of the mounting block 50. As described above, the mounting block 50 is fixed to the outer periphery of the rotating body 48 in the radial direction. Therefore, the rod 54 supported between the openings 50a has a tangential direction to the rotating body 48. It is suitable. Further, springs 58 are connected to both sides of the rod 54 between the two plate springs 56, and the end portions 56a of the two plate springs 56 are always attracted in a direction approaching each other. Furthermore, grip plates 60 facing each other are attached to both end portions 56a (upper and lower ends in FIG. 2) of the two leaf springs 56, and the container is supported by the pair of grip plates 60 facing each other. A grip 52 is configured. An arc-shaped concave surface 60a that abuts the neck portion of the container 4 (in this embodiment, the lower portion 4c of the flange portion 4a) is formed at the center of the opposing surfaces of the grip plates 60. A guide surface 60b that expands in the direction is formed.
[0026]
The holding plates 60 on both sides constituting the container holding portion 52 are fixed to the end portions 56a of the two leaf springs 56 and are attracted by the springs 58. The container 4 has the neck portion 4c of the holding plates 60 on both sides. The grip plates 60 are moved outwardly through the guide surfaces 60b while entering between the arcuate concave surfaces 60a while being pushed open, and then the grip plates 60 on both sides are gripped by the springs 58. In addition, since each holding plate 60 has guide surfaces 60b on both sides of the arcuate concave surface 60a, the guide plate 60b can enter and exit between the opposing arcuate concave surfaces 60a. . That is, the container 4 can enter and exit between the grip plates 60 from both the right side and the left side of FIG. A container gripping means 21 is constituted by a container gripping part 52 comprising the plate spring 56, the spring 58 and a set of gripping plates 60. The container gripping means 21 of this embodiment has a central rod 54 as a center. The container gripping portions 52 are provided at the symmetrical positions.
[0027]
An engaging member 64 having U-shaped concave portions 64a that engage with the guide rail 62 at both ends is fixed to the central portion of the rod 54 in the length direction. As shown in FIG. 3, the engaging member 64 is attached to the leaf springs 56 on both sides so as to be inclined. On the other hand, in the vicinity of the outer peripheral portion of the first reversing wheel 20, the upper and lower portions of the two container gripping portions 52 are switched with the rotational movement of the rotating body 48 by engaging with the U-shaped concave portion 64 a of the engaging member 64. The axis O of the rod 54 ₁ A guide rail 62 for rotating the container gripping means 21 about 180 degrees is arranged. The guide rail 62 has a front end 62a located on the first wheel 18 side at the container delivery position A (see FIGS. 1 and 4) from the first wheel 18 to the first reversing wheel 20, and the engaging member 64. The U-shaped recess 64a is engaged.
[0028]
Then, the guide rail 62 gradually enters the inside of the first reversing wheel 20 and the height thereof increases toward the container delivery position B between the first reversing wheel 20 and the first inlet wheel 22, and the first inlet At the delivery position B to the wheel 22, the container gripping means 21 is moved to the axis O of the rod 54 so that the highest position is reached and the top and bottom of the two container gripping parts 52 are inverted. ₁ It is designed to rotate around the center. Further, in the process of returning from the first inlet wheel 22 side to the end portion 62b on the first wheel 20 side, the same height as the delivery position B to the first inlet wheel 22 is arranged at the same radial position. .
[0029]
The operation of the container processing system including the container reversing wheels 20 and 38 having the above-described configuration will be described. The container 4 conveyed in an upright state by the conveyor 16 and introduced into the aseptic chamber 2 from the inlet 2a of the aseptic chamber 2 is held by the gripper 19 of the first wheel 18 and is rotated and conveyed. In this embodiment, the gripper 19 of the first wheel 18 holds a portion 4 b above the flange 4 a formed on the neck portion of the container 4.
[0030]
When the container 4 held by the gripper 19 of the first wheel 18 approaches the delivery position A to the first reversing wheel 20, the container gripping means 21 attached to the U-shaped mounting member 50 of the first reversing wheel 20 The lower portion 4c of the flange 4a is inserted between the grip plates 60 on both sides of the container grip portion 52 positioned below the upper and lower container grip portions 52. In addition, as shown in FIG. 3, the two container holding parts 52 are located up and down in the vertical direction at the transfer position A between the first wheel 18 and the first reversing wheel 20.
[0031]
Since the two grip plates 60 are fixed to the leaf springs 56 and are attracted to each other by the springs 58, the container 4 held by the gripper 19 of the first wheel 18 spreads the guide surfaces 60 b of the both grip plates 60. Pass through and fit into the arcuate recess 60a. On the other hand, the engaging member 64 integral with the container gripping means 21 has a downward U-shaped concave portion 64 a engaged with the tip 62 a of the guide rail 62. At this time, the end portion 62b of the guide rail 62 is engaged with the upward U-shaped recess 64a (see FIG. 3).
[0032]
When the first wheel 18 and the first reversing wheel 20 rotate together and the gripper 19 and the container gripping portion 52 of the container gripping means 21 move away from each other, the container 4 comes off the gripper 19 of the first wheel 18 and the container. It is gripped on the gripping part 52 side and rotated and conveyed by the rotation of the rotating body 48 of the first reversing wheel 20. As the first reversing wheel 20 rotates, the U-shaped recess 64a of the engaging member 64 moves upward and radially inward along the shape of the guide rail 62, and the upper and lower portions of the two container gripping portions 52 are moved up and down. The container gripping means 21 is rotated so as to be replaced (see FIG. 5). Thus, when the two container gripping parts 52 rotate 180 degrees and the top and bottom are switched, the container 4 gripped by one container gripping part 52 is inverted from the upright state to the inverted state.
[0033]
When the container 4 gripped by one container gripping portion 52 of the container gripping means 21 in an inverted state approaches the delivery portion B to the first inlet wheel 22 by the rotation of the rotating body 48 of the first reversing wheel 20, The first inlet wheel 22 is also provided with a gripper (not shown) similar to the first wheel 18 and is gripped by this gripper. When the first reversing wheel 20 and the first inlet wheel 22 further rotate, the container 4 held by the gripper of the first inlet wheel 22 is taken out from the container holding portion 52 of the first reversing wheel 20. As described above, the leaf spring 56 to which the two gripping plates 60 of the container gripping portion 52 are fixed is attracted in the direction in which they approach each other by the spring 58, and the gripper grips the container 4 while holding the container 4. The container 4 is taken out from the container gripping portion 52 by being pulled out from the container.
[0034]
As described above, at the delivery position A from the first wheel 18 to the first reversing wheel 20, the container gripping portion 52 positioned below grips the container 4, and then the rod 54 (in the tangential direction of the rotating body 48). The container gripping means 21 rotates 180 degrees around the axis), the container gripping part 52 gripping the container 4 moves upward, and the held container 4 is handed over to the gripper of the first inlet wheel 22. Then, the upper and lower two container gripping portions 52 that have delivered the container 4 to the first inlet wheel 22 return to the container delivery position A from the first wheel 18 again. At this time, since the container gripper 52 that has gripped the container 4 at the previous time is positioned upward and the other container gripper 52 has moved downward, this time, the container gripper 52 (upward The container gripping part 52) located in the position grips the container 4 below.
[0035]
The container 4 gripped in the inverted state by the gripper of the first inlet wheel 22 is delivered in an inverted state at the transfer part C to the first chemical liquid rinser 6. Since the container 4 is introduced into the first chemical liquid rinser 6 while being inverted, the cleaning liquid is immediately sprayed from the inner washing nozzle and the outer washing nozzle to wash the container 4. Thereafter, the chemical liquid injected into the container 4 is discharged by being rotated and conveyed in the rinser 6 in the inverted state, and is delivered to the first outlet wheel 24 in the inverted state. As described above, since the first chemical rinser 6 is always in an inverted state from the time of introduction to the time of discharge, cleaning can be started immediately after the introduction, and draining can be performed until the time of carrying out. Accordingly, the necessary cleaning time and draining time can be ensured without increasing the size of the rotating body of the rinser 6.
[0036]
The container 4 taken out from the first chemical liquid rinser 6 by the first outlet wheel 24 is delivered to the second inlet wheel 28 via the first intermediate wheel 26, and the second chemical liquid rinser 8 is entered from the second inlet wheel 28. be introduced. Even in the second chemical liquid rinser 8, the container 4 is always conveyed in an inverted state from the time of introduction to the time of unloading, and the necessary washing time and draining time can be secured and complete washing can be performed. In addition, since the container 4 is always conveyed in an inverted state in each of the wheels 24, 26, and 28 that convey the container 4 from the first chemical liquid rinser 6 to the second chemical liquid rinser 8, these wheels 24, 26, and 28 are also conveyed. The conveyance section in can also be used as a cleaning liquid discharge section.
[0037]
The container 4 that has been subjected to the second cleaning with the chemical liquid by the second chemical liquid rinser 8 is further in an inverted state through the second outlet wheel 30, the second intermediate wheel 32, and the third inlet wheel 34. Introduced in. Even in the finishing rinser 10, since it is always conveyed in an inverted state like the first and second chemical rinsers 6 and 8, a sufficient washing section and draining section can be secured without increasing the size of the rotating body. .
[0038]
The container 4 that has been cleaned in the finishing rinser 10 is taken out of the finishing rinser 10 in an inverted state by the third outlet wheel 36 and delivered to the second reversing wheel 38. The second reversing wheel 38 has the same configuration as that of the first reversing wheel 20, but the container 4 delivered from the third outlet wheel 36 is in an inverted state, so that the two reversing wheels 38 positioned vertically above and below are two. It is delivered to the container gripper 52 located above the container gripper 52. While the container 20 is rotated and conveyed in the second reversing wheel 38, the container gripping means 21 rotates around the rod 54, the upper and lower container gripping parts 52 are switched, and the upper container gripping part 52 is inverted. The container 4 that has been gripped is gripped in an upright state by the container gripping portion 52 that has moved downward.
[0039]
The container 4 returned to the upright state by the second reversing wheel 38 is introduced into the filler 12 via the filler inlet wheel 40. In the filler 12, liquid is filled in the container 4 while the container 4 is rotated and conveyed.
[0040]
The container 4 filled with the liquid is taken out from the filler 12 by the delivery wheel 42 from the filler 12 to the capper 14 and is introduced into the capper 14 as it is. After the container 4 is capped in the capper 14, it is taken out by the capper exit wheel 44, discharged onto the transport conveyor 46, and sent to the next step.
[0041]
In the container processing system according to the above configuration, the container 4 is inverted by the first reversing wheel 20 and then introduced into the rinsers 6, 8, 10, and the plurality of rinsers 6, 8, 10 and the inlet wheels 22, 28 of these rinsers are introduced. , 34, intermediate wheels 26, 32, and exit wheels 24, 30, 36, etc., are conveyed while being inverted, and a second reversing wheel 38 disposed between the most downstream rinser 10 and filler 12 Since it is reversed again to return to the upright state, there is no need to provide a mechanism for reversing the container 4 in the rinsers 6, 8, 10, and the structures of the rinsers 6, 8, 10 are simplified and rotated. A washing section and draining section can be secured over a sufficient length without increasing the size of the body. Further, since the structure of the container gripping portion 52 provided in the container gripping means 21 is extremely simple, the entire container processing system can be made compact and the cost can be reduced.
[0042]
In the above embodiment, the three rinsers 6, 8, 10 are connected in series, and the container 4 inverted by the reversing wheel 21 is sequentially introduced into the rinsers 6, 8, 10 while being inverted. However, the present invention is not limited to the configuration having a plurality of rinsers.The container is inverted by the reversing wheel on the upstream side of the rinser and inverted again on the downstream side of the rinser. Any container can be used as long as it returns to an upright state. In particular, there are two container gripping portions 52 of the container gripping means 21 in vertically symmetrical positions, and these container gripping portions 52 alternately grip and reverse the containers. That's fine. In addition, the number of container gripping portions 52 provided in the container gripping means 21 is not limited to two arranged at symmetrical positions as in the above-described embodiment.
