Description

  The present invention relates to a rotary filling apparatus capable of filling and capping various types of containers, and more particularly to a filling apparatus capable of filling a liquid that easily generates bubbles at a high speed.

  Many devices for filling a container or bottle with liquid have been disclosed. For example, a highly versatile bottle filling device corresponding to containers such as PET bottles and bottles having a size or shape as disclosed in Patent Document 1 is known. Patent Document 2 also relates to an apparatus that fills a continuously running container with a liquid.

The invention of Patent Document 1 includes a bottle supply device, a bottle filling device, a bottle capping device, and a PET bottle transfer mechanism therebetween, and latches one of the two-stage constricted portions of the upper opening of a filling container such as a PET bottle. Then, by hanging and filling or capping, handling bottles of different sizes and shapes eliminates the need for adjustments associated with lot changes. However, since the container is filled while being held vertically, there has been a problem that in filling with a highly foamable liquid, if the container is not filled slowly over time, it will leak.
Also, Patent Document 2 does not describe filling of a liquid having a highly foamable liquid.

Japanese Patent Laid-Open No. 2002-104587 (pages 2, 3 and 1) Japanese Patent Laid-Open No. 11-278594 (2nd, 3rd page, FIG. 1)

  Conventionally, when a highly foamable liquid is filled in a filling device or a filling capper device, bubbles are generated and overflow from the container, a predetermined amount cannot be filled, and the machine / container is more likely to be contaminated. There was a problem.

  When filling with foaming liquid, the liquid is likely to leak from the container as usual because the container is placed on a horizontal table and filled, so the liquid hits the bottom of the container when it is injected or the liquid hits the liquid surface. It was for making it foam.

  In order to suppress the generation of bubbles and to prevent filling, the filling speed (that is, the rotational speed of the rotor) must be set low, and high-speed processing cannot be performed.

  In order to solve the above-described problems, the present invention provides a configuration in which a filling base on which a container is mounted is automatically inclined during liquid filling to suppress generation of bubbles in the filling liquid as much as possible.

  Accordingly, it is an object of the present invention to provide a filling apparatus that can prevent contamination of containers and machines as much as possible when filling a highly foamable liquid and can perform high-speed processing.

The small filling capper device of the present invention includes a substrate table to which a rotary bearing portion of a shaft shaft is fixed, a rotational drive transmission portion disposed on a lower shaft shaft of the substrate table, and an upper shaft shaft on the substrate table. At least a rotating table arranged and a plurality of n filling tables attached along the periphery of the rotating table for filling the container with the liquid, the rotating table intermittently rotating, and the filling table A rotary-type filling capper device that sequentially performs filling and capping at a circumferential angle position determined by rotating a container mounted on the rotary table,
The filling table is composed of a container mounting plate, a back plate perpendicularly connected to the plate, a bevel member attached to the back plate, supporting the outer periphery of the container at two points, and fixing the bottle mouth in a predetermined position,
The rotary table includes n arms respectively connecting the back plates of the n filling bases, and n pieces for freely rotating each of the arms on a plane perpendicular to the circumferential direction of the rotary table. Arm fulcrum bearing,
When the filling table is within the range of the circumferential angle where the liquid filling machine is installed due to the rotation of the rotary table, the arm of the filling table is pushed up from the lower side and the axis of the mounted container is made vertical. And a tilting cam provided on a fixed table on the rotary bearing portion to be tilted from the nozzle, and the filling of the liquid from the nozzle reduces the amount of bubbles and enables high-speed filling. .

Further, in addition to the filling table tilting mechanism, within the range of the circumferential angle position, when the container mounting plate of the filling table is tilted from the horizontal by the tilt cam and the rotary table is temporarily stopped for liquid filling, A liquid filling machine is arranged to push up the container mounting plate by a predetermined amount in order to push up the bottle mouth of the container immediately below the nozzle tip of the liquid filling machine and put the tip of the nozzle into the bottle mouth. An air cylinder mechanism is provided on the fixed table at a circumferential angle position,
Since the filling liquid discharged from the nozzle of the liquid filling machine is filled along the inner wall of the container, the generation of bubbles is further reduced.

Further, the air cylinder mechanism is characterized in that when the container mounting plate is further pushed up, a roller is provided at the tip of the air cylinder mechanism to smoothly lift a predetermined amount.
The inclined filling table is provided with an adjusting mechanism capable of changing the fixing position of the air cylinder mechanism in accordance with the type and length of the container mounted thereon.

  Further, the inclined filling table is provided with an adjusting mechanism capable of changing the fixing position of the air cylinder mechanism in accordance with the type and length of the container mounted thereon.

  The present invention exhibits the following effects. That is, each container is mounted on each of a plurality of filling tables attached to the periphery of the turntable, and when the filling table is positioned just under the nozzle of the liquid filling machine by the rotation of the turntable, the filling table is inclined. Due to the mechanism, even when a highly foamable liquid is filled into the container at high speed, the generation of bubbles is suppressed, and high-speed filling is possible.

  In particular, the filling table automatically inclines only the rotation table circumferential angle range of the filling position, inclines the containers mounted on the filling table, and the other ranges do not incline the filling table at all, that is, the containers Since the construction such as capping can be performed while standing upright, there is an effect that the filling capper device can be designed in a small size.

  In addition, since it is supported at two points by a bevel member, it can easily accommodate various types of containers with different outer diameters or lengths, and by attaching adapters to the bevel parts, containers with different diameters at the top and bottom can also be used. Can be handled.

  The tip of the filling nozzle is inserted into the bottle mouth when the container is lifted by the air cylinder mechanism. For this reason, the generation of bubbles can be further reduced.

  Embodiments of the small filling capper apparatus of the present invention will be described below with reference to the drawings.

  1 and 2 show an overall configuration diagram of a small filling capper device. 1 is a front view and FIG. 2 is a plan view thereof.

  Here, reference numeral 100 denotes a substrate table, and a rotary bearing portion 100b of the shaft is fixed at the center of the substrate table 100, and the shaft 100a penetrates through the center thereof. In addition, a fixed table 100e is fixed to the upper portion of the rotary bearing portion 100b.

  A rotation drive transmission unit 100c that rotates the shaft intermittently is connected to the lower shaft shaft 100a of the substrate table 100.

  On the other hand, the rotary table 10 is connected to the upper shaft shaft 100 a of the substrate table 100. Further, an octagonal surface is provided at the tip of the shaft shaft 100a above it, and a reflecting mirror 100d is attached to each surface.

  In this embodiment, arm fulcrum bearings 12 are disposed at the lower part of the eight positions at equal intervals in the present embodiment. Each of these arm fulcrum bearings 12 serves as a fulcrum for the rotation axis of the arms 11 (eight). The rotation surface of the arm 11 is a surface orthogonal to the circumferential direction of the rotary table 10.

  Here, 2 shows the entire filling table, the filling table 2 on the right side of FIG. 1 shows a state when the container 1 is standing upright, and the filling table 2 on the left side of FIG. 1 shows a state when the container 1 is tilted.

  Each of these filling tables 2 is connected to an arm 11, and there are eight in this embodiment.

  The filling table 2 includes a container mounting plate 2a for placing the bottom surface of the container, a back plate 2b connected perpendicularly to the container mounting plate 2a, and a bevel-shaped bevel member 2c connected to the back plate 2b.

  The bevel member 2c supports the outer periphery of the container at two points and fixes the bottle mouth at a predetermined position. Moreover, when the filling stand 2 is inclined, the peripheral surface of the container 1 leans against the bevel member 2c, and the container 1 is further restricted from moving in the circumferential direction of the turntable 10.

  Reference numeral 13 denotes an inclined cam provided on the fixed table 100e, which is arranged coaxially with the rotary table 10. The inclined cam 13 has a thin cylindrical hollow shape, and the hollow cylindrical wall has a structure such that the diameter of the hollow cylindrical wall is below the eight arms as shown in FIGS.

  Therefore, the height of the hollow cylindrical wall, that is, the inclined cam 13 is set so that the cam height is increased as shown in FIG. The arm 11 is raised (in the embodiment, the arm 11 is tilted by about 30 degrees), and the cam 11 is set at a height such that the arm 11 is horizontal as shown in FIG.

  In FIG. 2, there is a hollow cylindrical tube wall or inclined cam 13 along the periphery of the rotary table 10, and the upper end of the inclined cam 13 is in contact with the cam facing plate 14 at the lower end of the eight arms 11. .

  In the embodiment of FIG. 2, the rotary table 10 is temporarily stopped, and the phase angle positions with respect to the central axis are referred to as (A) to (H).

  When liquid is injected into the containers 1 of the filling table 2 at the phase angle positions (B) and (C), the container 1 is inclined, so the arm 11 of the filling table 2 at the positions (B) and (C). The lower inclined cam 13 is formed to have a high height so as to push up the lower cam facing plate 14.

  The state of the filling platform 2 from the phase angle position (A) to (B) and from (C) to (D) is such that the container is smoothly tilted from upright to incline and from tilt to upright. The change in height is connected by a slowly changing curved surface.

  FIG. 5 shows an example of the inclined cam 13. Here, H1 is the height of the cam at which the arm 11 is horizontal, and H2 is the height of the cam at which the arm 11 is inclined by 30 degrees. The change in height from H1 to H2 is a curved surface that continuously changes as described above.

  In FIG. 1, the filling table tilting mechanism 15 indicates the entire tilting mechanism, and 14 indicates a cam facing plate with the tilting cam 13.

  Reference numeral 16 denotes an air cylinder mechanism fixed to the fixed table 100e, 17 denotes a tip roller, and 18 denotes a lever. This air cylinder mechanism 16 is provided at the positions (B) and (C), and when the filling table 2 is inclined at the position (B) or (C), it is shown in FIG. 3 (described later). Thus, in order to put the nozzle 20a of the liquid filling machine into the bottle mouth 1a of the container 1, it is a mechanism that pushes up the lower part of the container mounting plate 2a and pushes it up while tilting the filling table. At that time, the air cylinder is pushed up smoothly by the tip roller 17 of the air cylinder.

  The lever 18 has a screw for adjusting the push-up amount.

  Next, the overall configuration of the small filling capper device will be described in detail with reference to the plan view of FIG.

  In this embodiment, the filling table 2 of the turntable 10 is n = 8.

  Here, (A) to (H) show eight phase angle positions with respect to the central axis of each of the eight filling tables 2 when the rotary table 10 is temporarily stopped. The angular interval is 45 degrees in this embodiment. The work contents of the filling table 2 that has been rotated at each position are shown below.

(A): An empty container 1 is placed on an upright filling table 2.
(The tilting cam 13 makes the filling table 2 upright to tilt)
(B): First liquid injection (C): Second liquid injection
(The tilting cam 13 causes the filling stand 2 to be upright from the tilt)
(D): Space (E): Place lid on bottle mouth (F): Inner cap capping (G): Outer cap capping (H): Container removal

  Here, reference numeral 21 denotes a liquid filling machine fixing portion which is a stand of the liquid filling machine 20 and is fixed to the substrate table 100.

  Note that the injection of the first and second liquids at the positions (B) and (C) gives the work time twice as long as the work requiring time by the work at the two positions. is there. Two kinds of liquids such as seasoning liquid and oil such as dressing can be filled.

  Next, the liquid injection at the positions (B) and (C) will be described in more detail with reference to FIG.

  The left side of FIG. 3 shows details of the state at the position (C) where the liquid is injected into the container 1 from the nozzle 20a of the liquid filling machine 20.

  First, at (1) position (C) or (B), when the filling table 2 is brought, the arm 11 is raised by the inclined cam 13 and the filling table 2 is inclined by about 30 degrees. The container 1 placed on the filling table 2 is inclined, and the bottle mouth 1a comes directly below the nozzle 20a.

  Next, (2) the air cylinder mechanism 16 is automatically turned ON, the tip of the container is extended by a predetermined amount, and the tip of the tip roller 17 is tilted up to further tilt.

  By the pushing-up, the filling table 2 is rotated up around the arm fulcrum bearing 12, so that the nozzle 20 a is inserted into the bottle mouth of the container 1.

  When the liquid with high foaming property is injected into the container 1 by the mechanism operations of (1) and (2), foaming hardly occurs compared to the conventional case. Therefore, the intermittent rotation speed of the turntable 10 can be increased to enable high-speed filling.

  In addition, even if the position of the bottle mouth 1a of the container 1 changes depending on the type of the container, the position of the nozzle 20a is adjusted to adjust the push-up amount of the axial radial direction adjusting mechanism 23 and the air cylinder mechanism 16 according to the type. Adjustment can be easily made with the screw of the adjuster 19.

  Next, the outer cap capping on the right side of FIG. 3 will be described. This position corresponds to (G).

  The capping mechanism includes the work of the inner cap capping mechanism 30 performed at the position (F) and the outer cap capping mechanism 40 at the position (G). Press the switch to select whether to work. One of the selected operations is performed, and the other operation is passed.

  The embodiment of FIG. 3 shows a state where the outer cap capping is selected, stopped at the position (G), and the outer cap operation is performed. Reference numeral 43 denotes a container fixing mechanism that temporarily prevents the container 1 from rotating. The container fixing mechanism 43 rotates the lid 1b of the bottle mouth 1a with a predetermined torque, tightens it, and plugs it. 41 and 42 are stopper position adjusting mechanisms in the outer stopper capping mechanism 40.

  The adjuster 19 in FIG. 3 can be moved in the axial direction and screwed, and the adjuster 19 can be moved up and down (indicated by a two-dot chain line in FIG. 3) to match the shape of the container and the characteristics of the filling liquid. Thus, it is possible to increase or decrease the push-up amount of the filling table 2.

  Next, the overall flow of container movement will be described with reference to FIG.

  The empty container 1 thrown into one of the filling tables 2 at the position (A) rotates and comes to the position (B) and stops temporarily. By this time, the filling table 2 is inclined 30 degrees from the horizontal.

  In position (B), the liquid is injected and filled from the nozzle 20a by half of the container.

  At that time, the liquid filling machine 20 is provided with an optical sensor 22, and the central shaft shaft 100a is provided with a total of eight reflecting mirrors 100d in the regular octagonal direction, and the optical sensor 22 faces the reflecting mirror 100d. When this occurs (that is, when the rotary table 10 is temporarily stopped), the reflected light is detected, the presence or absence of the container is confirmed, and the liquid filling machine 20 is operated. For this reason, the liquid is not injected into the filling table in which the container is not loaded.

  When the filling table 2 comes to the position (C) and stops temporarily, the same confirmation is made, and only when there is a container, the remaining half of the filling is performed. In this explanation, an example in which the injection time is shortened by injecting the liquid filling machines 20 at two locations in half to one container is shown. However, different liquids such as dressing are injected from each liquid filling machine 20. There is also a case.

  As described above, it is confirmed that the container 1 is placed on the filling table 2 by the optical sensor 22 and the reflecting mirror 100d attached in the regular octagonal direction, and the liquid filling machine 20 and the inner cap capping mechanism 30 are confirmed. Then, the outer cap capping mechanism 40 is operated.

  The positions (D) and (E) are positions where the lid 1b is placed on the mouth part 1a and the bottle mouth 1a of the container 1 into which the liquid has been injected. The operation of placing the lid 1b on the bottle mouth 1a is performed manually by the operator. Of course, an automatic lid supply mechanism may be provided here.

  In the position (F), when the inner stopper is selected, the inner stopper capping mechanism 30 is operated and the lid 1b is tightened. According to the size of the container 1, its position is set in advance by the bottle mouth position adjusting mechanism 31.

  In the position (G), when the outer plug is selected, the outer cap capping mechanism 40 is operated and the lid 1b is tightened. The position is set in advance by the stopper position adjusting mechanisms 41 and 42 according to the size of the container 1.

  When the outer cap capping mechanism 40 operates, the container fixing mechanism 43 presses the container 1 and the lid is wound with a predetermined torque.

  The position (H) is a position where the container 1 of the filling table 2 that has come here is discharged to the carry-out mechanism 50 of the roller conveyor on the outside.

  The carry-out mechanism 50 includes a container discharge mechanism 51 for moving the container 1 from the filling table 2 onto the roller conveyor. The container discharge mechanism 51 is configured such that the container discharge plate 51a is positioned radially inside by an air cylinder before the filling table 2 rotates, and is operated outside when the filling table on which the container 1 is mounted arrives. 1 is pushed out to the discharge mechanism 50 side.

  At the position (A), the empty container 1 is put on the empty filling table 2 and the above operation is repeated.

  When filling and capping containers 1 having different types and sizes of lids, the inner cap and the outer cap are selected (by pressing a selection switch button not shown), and the liquid filling machine 20 and adjuster 19 are adjusted according to the size of the container. Adjustment and adjustment of the inner plug capping mechanism 30 or the outer plug capping mechanism 40 are performed.
