  2. Description of the Related Art Conventionally, there has been known a liquid fixed-quantity filling apparatus that can automatically clean all necessary portions in the apparatus. For example, the valve chamber includes a casing having a valve chamber, a metering cylinder that incorporates a piston and allows a filling liquid to flow into and out of the valve chamber by a stroke of the piston, and a rotating body that is accommodated in the valve chamber. Has a cylindrical stepped peripheral surface composed of a small-diameter portion and a large-diameter portion, and an inlet port and an outlet port are provided on the peripheral wall of the small-diameter portion at intervals in the circumferential direction, and the end wall of the small-diameter portion Alternatively, a communication port is provided on the peripheral wall, the metering cylinder is connected to the communication port, and the rotating body has an outer peripheral surface that is slidably fitted to the peripheral surface of the small diameter portion in the circumferential direction and the axial direction. The rotating body is provided with a filling liquid passage for alternately connecting the inlet port and the outlet port to the communication port as the rotating body rotates. Thus, a liquid fixed-quantity filling device is proposed in which the rotating body is moved between a filling position where the rotating body is positioned at the small diameter portion and a cleaning position where the rotating body is positioned at the large diameter portion. (For example, refer to Patent Document 1).

Conventionally, a rotary filling valve for transferring and filling a liquid or semi-liquid material in a fixed amount is known.

  However, in the rotary filling device according to Patent Document 1, it is desired to simplify the internal structure of the device, particularly the structure of the rotating body and the valve chamber, in order to enhance the cleaning effect.

  In addition, the rotary filling device according to Patent Document 2 takes time for cleaning, and is inefficient when manufacturing foods and the like. When handling food, etc., it is necessary to periodically clean the apparatus before starting the filling operation. Cleaning is also required when the rotary filling valve is used for food production or the like. However, simply supplying a cleaning liquid instead of filling material to the rotary filling valve is not sufficient. In particular, the gap between the valve chamber and the rotating body and the gap between the cylinder chamber and the shuttle-type piston cannot be cleaned and removed by simply supplying the cleaning liquid. For this reason, all rotary type filling valves including pumps must be disassembled and washed by hand, which is extremely inefficient when producing foods. In addition, in this type of rotary type filling device, the original purpose of this type of rotary type filling device is that when a food containing solid matter is filled in order to send the filling material under pressure by a pump, the solid matter is broken. Problems arise that conflict with In particular, in this rotary type filling device, the outlet of the filling tank and the suction port of the pump are directly connected, and the transfer path from the pump to the filling valve is long, so that it is extremely damaged when filled with soft solids such as pulp. Problems arise. Moreover, the problem which clogs a rotary valve etc. also arises with the solid substance which was crushed and dumpled. Furthermore, in this rotary type filling device, if the diameter of the pipe connecting the pump to the filling valve is increased, there is a problem that a high pressure is required accordingly, so that food containing large solids cannot be filled. .

  Therefore, the present invention is a rotary filling device that can automatically clean the inside of the device without disassembling the device, the internal structure is simple, and the food containing solid matter is not damaged by the solid matter. It aims at providing the rotary type | mold filling apparatus which can be filled.

Moreover, the cross-sectional shape of a cylinder chamber can be made circular, and a notch part can also be provided in a part. The material of the shuttle type piston is not particularly limited, but a soft elastic material is preferable from the viewpoint of ensuring adhesion with the cylinder chamber. Examples of the soft elastic material include nylon, Teflon (registered trademark), plastic, and the like, and nylon and Teflon (registered trademark) are more preferable. Further, the shape of both ends of the shuttle type piston, that is, the shape of the surface of the piston toward the inlet and outlet of the cylinder chamber is not particularly limited, but it is preferable to form a recess. The concave portion is more preferably a curved surface in order to reduce the adhesion surface of food or the like. Moreover, in order to reduce adhesion of food etc., a recessed part can also be made into a mirror surface finish.

  FIG. 4 is a longitudinal sectional view of a rotary filling valve according to an embodiment of the present invention. As shown in FIG. 4, the rotating body 37 has a cylinder chamber 35 penetrating in the radial direction. A shuttle type piston 36 is contained in the cylinder chamber 35, and can be reciprocated in the axial direction of the cylinder chamber 35 by the rotational movement of the rotating body 37. The rotating body 37 is disposed so as to rotate while being in sliding contact with the inner periphery of the casing 34, and the cylinder chamber 35 penetrating the rotating body 37 in the radial direction has a casing each time the rotating body 37 rotates approximately 180 degrees. 34 is in a position to communicate with the inlet 45 and the outlet 46 at the same time. When the cylinder chamber 35 communicates with the outlet 46 of the casing 34, the edge on the outlet 46 side slightly covers the cylinder chamber 35, and the portion covering the cylinder chamber 35 projects the piston 36 toward the outlet 46. It becomes a stopper to stop. The cylinder chamber 35 has a long hole-like cross section, and the piston 36 fitted in the cylinder chamber 35 has the same shape. This shape serves as a rotation restricting means for preventing the relative rotation of the piston 36 in the cylinder chamber 35. Yes.

  FIG. 5 is an explanatory view of the filling operation of the rotary filling valve according to one embodiment of the present invention. As shown in FIG. 5, the rotating body 37 is positioned at the filling position (see FIG. 6A), the casing 45 is installed with the inlet 45 facing upward and the outlet 46 facing downward. Is installed so that the outlet of the filling tank 51 communicates. (1) The filling liquid in the filling tank 51 causes the piston 36 to exit from the cylinder chamber 35 due to its own weight, or pressurized air in the filling tank 51 generated by its own weight and air supplied from the air supply port 71 (see FIG. 3). By descending to the 46 side, it flows into the cylinder chamber 35 (FIG. 5A). (2) The servo motor 83 (see FIG. 1) is driven and transmitted to the gear, the rotating body 37 rotates approximately 180 degrees, and the rotating body 37 stops at a position where one end of the cylinder chamber 35 communicates with the inlet 45 (see FIG. 1). 5 (c)). (3) The piston 36 is lowered again to the outlet 46 side by its own weight or its own weight and the pressurized air in the filling tank 51, and at that time, the filling liquid previously entered in the cylinder chamber 35 is pushed out from the outlet 46, The container a (see FIG. 3) is filled (FIG. 5 (d)). (4) The servo motor 83 is driven again so that the rotating body 37 rotates approximately 180 degrees, and the rotating body 37 stops at a position where the other end of the cylinder chamber 35 communicates with the inlet 45 (FIG. 5 (f)). This completes one filling operation. Hereinafter, by appropriately repeating the operations (1) to (4), it is possible to sequentially fill the new container with the filling liquid. Note that the timing of the rotating body 37 can be freely set by changing the control of the servo motor 83.

  FIG. 6 is an explanatory view of the cleaning operation of the filling apparatus according to the embodiment of the present invention. As shown in FIG. 6, when the piston rods (see FIGS. 1 and 2) of the short air cylinder 93 and the long air cylinder 94 are pulled together, the rotating body 37 is located in the small diameter portion 41 (also referred to as a filling chamber). Then, it is positioned at the filling position (FIG. 6A). When the piston rods of both cylinders 93 and 94 are pushed together, the rotator 37 is located in the large-diameter portion 42 (also referred to as a cleaning chamber) and is positioned at the cleaning position (FIG. 6B). When the piston rod of the short air cylinder 93 is pushed and the piston rod of the long air cylinder 94 is pulled, it is positioned between the filling position and the cleaning position (FIG. 6C). This intermediate position is also a cleaning position and an air bleeding position. At this intermediate position, the communication between the filling chamber 41 and the cleaning chamber 42 is blocked by the rotating body 37.

  Next, the cleaning operation in the apparatus will be described. The states of the rotating body 37, the spool 63, and the like differ depending on the part to be cleaned. That is, cleaning is sequentially performed for each of the system of the cylinder chamber 35 and the shuttle type piston 36, the system of the filling nozzle 32, and the system of the rotating body 37.

  When the system of the cylinder chamber 35 and the shuttle type piston 36 is cleaned, the rotating body 37 is kept at the intermediate cleaning position (FIG. 6C). Further, the spool 63 is positioned in the middle, and the adapter 68 is attached to the filling nozzle 32. In this manner, when the cleaning liquid is supplied to the filling tank 51 together with steam or the like as necessary, the cleaning liquid or the like flows from the filling tank 51 into the filling chamber 41. Most of the cleaning liquid flows on the rear side of the rotating body 37, but approximately half of the cylinder chamber 35 faces the inlet 45 and outlet 46 of the casing 34, so that the cleaning liquid or the like flows into the cylinder chamber 35. When the rotating body 37 is rotated approximately every 180 degrees as in the filling, the piston 36 slides in the cylinder chamber 35 and is cleaned. The washing liquid after washing goes out through the adapter 68 from the outlet 64 of the filling nozzle 32.

  When cleaning the system of the filling nozzle 32, the rotating body 37 is set to the filling position (FIG. 6A), the spool 63 is positioned in the large diameter portion 66 which is the ascending limit, and the cleaning liquid supply port 67 is opened. Keep it. At this time, the rotating body 37 is stopped. In this state, when the cleaning liquid or the like is supplied from the cleaning liquid supply port 67, the spool 63, the small diameter portion 65, and the large diameter portion 66 are cleaned. The cleaning liquid after cleaning goes out from the outlet 64 of the filling nozzle 32. Separately from this cleaning operation, the rotating body 37 is placed at the position shown in FIG. 6C, the spool 63 is positioned in the large diameter portion 66 that is the ascending limit, and the cleaning liquid water supply port 67 (here, referred to as a drain port). ) Is open. At this time, the rotating body 37 is stopped. In this state, when cleaning liquid or the like is supplied to the filling tank 51, the cleaning liquid or the like closes the cylinder chamber 35 with the piston 36, so that it passes through the casing 34, flows through the L-shaped pipe 52, and flows into the filling nozzle 32. . If the adapter 68 side is closed, the cleaning liquid or the like flows into the large diameter portion 66 of the filling nozzle 32, and the spool 63, the small diameter portion 65, and the large diameter portion 66 are cleaned. The cleaning liquid after cleaning exits the drain port 67.

  The cleaning of the system of the rotator 37 will be described. The filling nozzle 32 closes the spool 63 and closes the inlet 62 to place the rotator 37 in the cleaning position, that is, in the cleaning chamber (FIG. 6B). ). In this way, the cleaning liquid or the like is supplied to the filling chamber 41 via the filling tank 51. Each part of the filling chamber 41 and the rotating body 37 is cleaned by the cleaning liquid flowing into the filling chamber 41, and the space between the peripheral surface of the filling chamber 41 and the outer peripheral surface of the rotating body 37 is also cleaned. The cleaning liquid after cleaning is discharged out of the filling chamber 41 from the drain port 48. The cleaning liquid remaining in the L-shaped tube 52 can be discharged by opening the spool 63 and the adapter 68.

  When starting the filling operation, if the rotating body 37 is positioned at the intermediate cleaning position which is also the air venting position (FIG. 6C), the filling body can be quickly filled without rotating the rotating body 37. 51 can be introduced into a filling liquid passage from the filling nozzle 32 to the filling nozzle 32, and air staying in a series of filling liquid passages from the filling nozzle 32 to the filling tank 51 is gradually upstream from the filling nozzle 32 through the filling liquid passage. And finally discharged into the filling tank 51.

  By using this filling device, a CIP-compatible device for filling seaweeds such as pulp, side dishes, squid salted seaweed, thread mozuku, potato salad, boiled hijiki, and other foods mixed with solids Can be used as For example, the cleaning liquid can be automatically supplied from the cleaning liquid supply port 67 or the filling tank 51, and by combining with a rotary pump capable of CIP, it can also be used as a CIP compatible filling device. Moreover, a low-viscosity filling can be accommodated by attaching a tip spool.
