[0018]
The suction valve 19 includes a valve cone 25 and a spring 26. The valve cone 25 is urged upward by the spring 26, and the suction valve 19 is normally closed. When the piston 36 is lowered to generate a negative pressure in the valve housing 23, the valve cone 25 is lowered against the urging force of the spring 26, and the suction valve 19 is opened.
[0019]
When the suction valve 19 is opened, the liquid food in the tank 11 is discharged from the discharge opening 18, flows through the valve body 22, and is supplied into the valve housing 23 through the suction valve 19, and then the elbow pipe 24 is supplied to the weighing space 20.
[0020]
Further, the measuring space 20 communicates with the inside of the measuring supply pipe 13 via the discharge valve 40. A nozzle 61 is attached to the lower end of the metering pipe 13, and the nozzle 61 has a predetermined shape set corresponding to the type of carton 15 filled with liquid food.
[0021]
The discharge valve 40 includes a valve cone 42 and a spring 43. The valve cone 42 is urged upward by the spring 43, and the discharge valve 40 is normally closed. When the piston 36 is raised to increase the pressure in the valve housing 23, the valve cone 42 is lowered against the urging force of the spring 43, and the discharge valve 40 is opened. As a result, the liquid food in the measurement space 20 is supplied to the measurement supply pipe 13 via the valve housing 23 and discharged from the nozzle 61.
In order to forcibly open the suction valve 19 and the discharge valve 40, a valve opening drive device 27 is disposed above the tank 11, and the valve opening drive device 27 penetrates the upper wall of the tank 11. A mandrel 29 extending downward is provided. Therefore, the suction valve 19 and the discharge valve 40 can be simultaneously opened by lowering the mandrel 29 by the valve opening drive device 27.
[0022]
Meanwhile, a liquid food supply pipe 51 is connected to the lower part of the side wall of the tank 11. The liquid food supply pipe 51 is connected to a liquid food supply source (not shown) via a liquid food supply valve 52, and by opening and closing the liquid food supply valve 52, liquid food is supplied into the tank 11 in the direction of the arrow.

[0026]
When the liquid food supply valve 52 (FIG. 2) is opened, the liquid food supplied from a liquid food supply source (not shown) is supplied into the tank 11 through the liquid food supply pipe 51. The level of the liquid food in the tank 11 is detected by the level sensor 56, and the liquid food is always kept at the same height by opening and closing the liquid food supply valve 52.
[0027]
In the suction mode, as shown in FIG. 3, the piston 36 of the metering pump 12 is lowered to a predetermined position below the metering stroke by lowering the piston rod 38, and the metering space 20, elbow pipe 24 and A negative pressure is generated in the valve housing 23. At this time, the discharge valve 40 is kept closed, but the suction valve 19 is opened by the negative pressure in the valve housing 23. Accordingly, the liquid food in the tank 11 is sucked into the weighing space 20. Then, the carton 15 is raised at the timing when the lowering of the piston 36 is finished, and is placed at the filling start position.
[0028]
Next, in the delivery mode, as shown in FIG. 4, the piston 36 is raised to a predetermined position above the metering stroke by raising the piston rod 38, and the metering space 20, the elbow pipe 24 and the valve housing 23. The pressure inside becomes high. At this time, the suction valve 19 is kept closed, but the discharge valve 40 is opened by the pressure in the valve housing 23. Therefore, the liquid food in the measurement space 20 is supplied to the measurement supply pipe 13.
[0029]
The liquid food fed to the metering pipe 13 flows down through the metering pipe 13 and is discharged from the nozzle 61 to fill the carton 15. Then, as the piston 36 moves up, the carton 15 is lowered. 25 and 42 are bubble cones, and 26 and 43 are springs.
[0030]
Next, the operation of the carton 15 will be described.
[0031]
FIG. 5 is a diagram showing the operation of the carton in the first embodiment of the present invention. (A) in the figure shows the state of the carton 15 at the end of the suction of the liquid food in the suction mode, (b) in the figure shows the state of the carton 15 at the start of filling in the delivery mode, and (c) in the figure shows the delivery. The state of the carton 15 during filling in the mode is shown, and (d) in the figure shows the state of the carton 15 at the end of filling in the delivery mode.
[0032]
In the figure, 13 is a metering pipe, 15 is a carton, 61 is a nozzle, and S1 is the liquid level of the liquid food.
[0033]
When the suction mode ends, the carton 15 is raised in the direction of the arrow from the standby position at the lower end, as shown in FIG.
[0034]
In the delivery mode, as shown in FIG. 5B, the carton 15 is placed at the filling start position at the upper end, filling of the liquid food is started, and the liquid food flows in the direction of the arrow. At this time, the bottom of the carton 15 is brought closest to the lower end of the nozzle 61.
[0035]
Then, as shown in (c) of the figure, the carton 15 is moved in the direction of the arrow as the filling of the liquid food proceeds. In this case, when the nozzle 61 is separated from the liquid level S1 of the liquid food in the carton 15, the liquid level S1 is bubbled to generate bubbles, and the bubbles are caught in the liquid food. Therefore, the nozzle 61 is always immersed in the liquid food while being filled with the liquid food.
[0036]
In this way, when filling is completed, as shown in (d) of the figure, the carton 15 is placed at the filling completion position, and then moved further in the direction of the arrow to wait as shown in (a) of the figure. Placed in position and replaced with the next empty carton 15.
[0037]
By the way, if the liquid food adhering to the nozzle 61 drips when the filling is completed and the nozzle 61 moves away from the liquid surface S1, the carton 15 and the surroundings of the weighing device and the like are soiled.
[0038]
Therefore, a mesh (not shown) is provided at the lower end of the nozzle 61, and the liquid food is held by the mesh using surface tension so as to prevent the liquid food from dripping.
[0039]
FIG. 1 is an exploded perspective view of a main part of a nozzle according to the first embodiment of the present invention, FIG. 6 is a perspective view of a main part of the nozzle according to the first embodiment of the present invention, and FIG. The perspective view of the nozzle in embodiment, FIG. 8 is principal part sectional drawing of the nozzle in the 1st Embodiment of this invention.
[0040]
In the figure, 61 is a nozzle, 62 is an upper end and a lower end are opened, and a nozzle body attached to the metering pipe 13 (FIG. 2), 63 is detachably disposed on the nozzle body 62, and the upper end And an adapter having a lower end opened.
[0041]
The nozzle body 62 has a circular section corresponding to the shape of the metering supply pipe 13 and a cylindrical portion 62a as an upper half having a circular shape, and a cross section of the upper end corresponding to the shape of the cylindrical portion 62a. It has a shape and is gradually enlarged as it goes downward, and the lower end cross section corresponds to the shape of the carton 15 and is composed of, for example, an enlarged portion 62b as a lower half portion having a square shape. The cylindrical portion 62a and the enlarged portion 62b are integrally formed with each other. Further, the cylindrical portion 62a includes a small diameter portion 81 having a small diameter on the upper side and a large diameter portion 82 having a large diameter on the lower side. The large diameter portion 82 and the enlarged portion 62b have a double tube structure.
[0042]
The adapter 63 is made of a frame having a square shape, for example, corresponding to the shape of the carton 15, and has a discharge port M for discharging liquid food at the lower end.
[0043]
In the adapter 63, a mesh unit 93 composed of first to third meshes is disposed. Therefore, the mesh unit 93 can hold the liquid food using the surface tension and prevent the liquid food from dripping when the nozzle 61 moves away from the liquid surface S1 (FIG. 5).
[0044]
For example, when changing the liquid food to be weighed, it is necessary to clean the tank 11, the metering supply pipe 13, the nozzle 61, etc. of the metering device, but the liquid adhering to the mesh unit 93 and a seal member described later. Since it is difficult to remove food, particularly liquid food that has entered between and adhered to each of the first to third meshes, the work related to cleaning is extremely troublesome.
[0045]
Therefore, the nozzle 61 is detachably disposed on the metering supply pipe 13. For this purpose, a thin insertion portion 65 is formed on the outer peripheral surface of the lower end portion of the nozzle main body 62 (enlarged portion 62b), and the nozzle main body 62 and the adapter 63 are connected by inserting the insertion portion 65 into the adapter 63. Can be brazed.
[0046]
Further, in order to maintain the state in which the nozzle body 62 and the adapter 63 are joined to each other, a locking piece 67 serving as a locked portion is formed at two positions on the upper end of the body portion 66 of the adapter 63. Is done. The locking piece 67 has a pair of first hooks 68 extending from the outside to the inside at the upper end, and is accommodated in the nozzle body 62 when the nozzle body 62 and the adapter 63 are joined together. Thus, it is formed thinner than the main body 66.
[0047]
The nozzle body 62 is provided with a pair of locking projections 69 as locking portions so as to be detachable from the first hook 68 and movable in the longitudinal direction. Includes a second hook 71 having a shape corresponding to the first hook 68 at the lower end and extending from the inside toward the outside. Further, in order to pull up the locking projection 69 upward, a stainless steel string 72 as a connecting means is provided, and the lower end of the string 72 is attached to the upper end of the locking projection 69.
[0048]
Therefore, by engaging the first hook 68 and the second hook 71 and pulling the string 72 upward, it is possible to maintain the state where the nozzle body 62 and the adapter 63 are joined together. A slit (not shown) having a shape corresponding to the shape of the locking piece 67 is formed at the lower end of the enlarged portion 62b so that the locking piece 67 can be accommodated in the nozzle body 62. The guide groove 70 is formed so that the string 72 can be penetrated and guided.
[0049]
Further, in order to hold the string 72 in a lifted state, a support flange 75 as a support portion is formed at a predetermined position of the small diameter portion 81 so as to protrude radially outward, and the string is formed on the support flange 75. A guide groove 83 for penetrating 72 is formed. A ring 76 as a supported body is attached to the upper end of the string 72.
[0050]
The string 72 extends upward in the guide groove 70 and protrudes from the large diameter portion 82, further extends upward in the guide groove 83, protrudes from the guide groove 83, and is connected to the ring 76. . A spacer 77 is disposed between the support flange 75 and the ring 76 in order to give a predetermined tension to the string 72 by a wedge action. The string 72, the support flange 75, the ring 76, and the spacer 77 constitute locking state holding means for holding the locking state between the locking piece 67 and the locking protrusion 69.
[0051]
The spacer 77 is composed of first and second wedge bodies 77a and 77b having a semicircular shape, and is cylindrical by combining the first and second wedge bodies 77a and 77b. It becomes the shape. Each of the first and second wedge bodies 77a and 77b includes a cylindrical portion a, and first and second tapered portions b and c formed at the upper and lower ends of the cylindrical portion a, The upper surface of the first taper portion b forms a first taper surface S11 that extends obliquely upward from the radially inner side toward the radially outer side, and the lower surface of the ring 76 causes a radial direction from the radially inner side. A second taper surface S12 extending obliquely upward toward the outside is formed, and a third taper extending obliquely downward from radially inward to radially outward is formed by the lower surface of the second taper portion c. A surface S13 is formed, and the upper surface of the support flange 75 forms a fourth tapered surface S14 extending obliquely downward from the radially inner side to the radially outer side.
[0052]
Incidentally, a holding portion 92 is formed at the lower end of the adapter 63 so as to protrude inward, and the discharge port M is set by the inner peripheral edge of the holding portion 92. The holding portion 92 accommodates and holds the mesh unit 93 and a seal member (not shown) made of a rubber annular body in the adapter 63. Therefore, the four sides of the mesh unit 93 are set shorter than the four sides of the inner peripheral surface of the adapter 63 and longer than the four sides of the peripheral edge of the discharge port M, respectively.
[0053]
The insertion portion 65 is set to be shorter than the adapter 63 in the vertical direction. When the insertion portion 65 is inserted into the adapter 63, the mesh unit 93 and the seal member are pressed against the holding portion 92 by the lower end of the insertion portion 65. be able to.
[0054]
The mesh unit 93 is formed by laminating the first to third meshes in direct contact with each other.
[0055]
In the nozzle 61 having the above-described configuration, when the adapter 63 is attached to the nozzle body 62, first, the mesh unit 93 and the seal member are inserted into the adapter 63, and then the first hook 68 and the second hook 71 are locked. Then, the string 72 is pulled upward. Subsequently, the first and second wedge bodies 77a and 77b are placed between the support flange 75 and the ring 76, and each second taper portion c and the support flange 75 are clamped by an annular clamp 91. Thus, the spacer 77 is set. At this time, the ring 76 and the support flange 75 are pressed by the first and second taper portions b and c, respectively, and tension is applied to the string 72 in the raised state. In this way, the adapter 63 can be attached to the nozzle body 62.
[0056]
Further, when removing the liquid food adhering to the mesh unit 93 and the seal member, particularly the liquid food adhering between the first to third meshes, first, each second taper portion by the clamp 91 is removed. c and the clamp of the support flange 75 are released, the spacer 77 is removed from between the support flange 75 and the ring 76, and the string 72 is moved downward. Subsequently, the engagement between the first hook 68 and the second hook 71 is released, the adapter 63 is removed from the nozzle body 62, and the mesh unit 93 and the seal member are taken out from the adapter 63. The liquid food adhering to the seal member, in particular, the liquid food adhering to the first to third meshes can be removed. In addition to the liquid food, fat mass, sludge and the like attached to the mesh unit 93 and the seal member can be removed. Therefore, the work concerning cleaning can be simplified.
[0057]
Next, the first to third meshes will be described.
[0058]
9 is a plan view of the first and third meshes in the first embodiment of the present invention, FIG. 10 is a cross-sectional view taken along the line XX of FIG. 9, and FIG. 11 is a first view in the first embodiment of the present invention. It is a top view of 2 meshes.
[0059]
9 and 10, reference numeral 178 denotes an annular frame having a shape and dimensions that can be accommodated in the adapter 63 (FIG. 1), and 179 is parallel to the lateral side of the frame 178 at a predetermined pitch. The arranged first wire 180 is a second wire arranged at a right angle to the first wire 179 and parallel to the vertical side of the frame 178 at a predetermined pitch. Yes, each pitch of the first and second wires 179 and 180 represents a mesh size, and is set to 0.8 [mm], for example. The frame 178 and the first and second wires 179 and 180 are all made of metal, and the frame 178 and the first and second wires 179 and 180 are welded.
[0060]
In FIG. 11, reference numeral 181 denotes an annular frame having the same shape and dimensions as the frame 178, and 182 denotes a predetermined angle θ1 (for example, 45 °) with respect to the side of the frame 181 at a predetermined pitch. The first wire 183 disposed at a right angle to the first wire 182 and at a predetermined pitch with respect to the vertical side of the frame 181 at a predetermined angle θ2 (for example, 45 [° ], The pitch of each of the first and second wires 182 and 183 represents a mesh size, for example, 0.8 [mm]. The frame 181 and the first and second wires 182 and 183 are all made of metal, and the frame 181 and the first and second wires 182 and 183 are welded.
[0061]
In this case, the first and second wires 179 and 180 in the first and third meshes, and the first and second wires 182 in the second mesh disposed between the first and third meshes, Since 183 is disposed at an angle different from each other, surface tension can be generated without making the mesh sizes of the first and third meshes different from the mesh sizes of the second mesh.
[0062]
The first and second wires 179 and 180 in the first and third meshes and the first and second wires 182 and 183 in the second mesh both have a circular cross section. Compared with the case where a perforated plate is used, since the area which contacts a liquid food is large, sufficient surface tension can be generated. Accordingly, since the number of meshes to be stacked can be reduced, the axial dimension of the nozzle 61 can be reduced.
[0063]
Next, a second embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st Embodiment, the description is abbreviate | omitted by providing the same code | symbol.

In this case, the nozzle main body 62 and the adapter 63 are joined to each other, and in order to maintain the joined state, the two pieces at the upper end of the main body portion 66 of the adapter 63 have locking pieces as locked portions. 67 is formed to protrude, and the locking piece 67 includes a pair of first hooks 68 extending from the outside to the inside at the upper end.
[0066]
In addition, a thin lever housing portion 101 is formed on two opposing side surfaces of the lower end portion of the enlarged portion 62b so as to correspond to the locking piece 67, and a pair of levers 102 serving as a locking portion is formed in the lever housing portion 101. Is movable around the axis sh, that is, swingable in the direction of the arrow in FIG. Each lever 102 includes a pair of second hooks 104 extending from the inside toward the outside at the lower end, and the first and second hooks 68 and 104 are moved by rotating the levers 102 away from each other. It can be locked.
[0067]
Meanwhile, each lever 102 is detachably attached to the lever accommodating portion 101. For this purpose, as shown in FIG. 15, an annular convex portion 108 is formed at the upper end of the lever accommodating portion 101 corresponding to each axis sh, and a lever insertion port 109 is formed at the center of the convex portion 108. Is done. On the other hand, each lever 102 is formed with a circular convex portion (not shown) at a portion corresponding to the shaft sh, and the lever 102 is inserted into the lever accommodating portion 101 by inserting the convex portion into the lever insertion port 109. Can be attached. The lever 102 is formed with a thin fin 111 at the edge portion on the distal end side of the second hook 104.
[0068]
Therefore, after the lever 102 is attached to the lever accommodating portion 101, the nozzle body 62 and the adapter 63 are joined to each other, and the levers 102 are rotated away from each other, thereby the first hook 68 and the second hook. When 104 is locked, each fin 111 enters the back side of the first hook 68, so that each lever 102 does not come off from the lever accommodating portion 101. In order to prevent the first hook 68 and the second hook 104 from being locked once (once) to the upper edge 113 of the lever accommodating portion 101, the locking is easily released. The wedge can be formed. In that case, the wedge constitutes a locking state holding means for holding the locking state between the locking piece 67 and the lever 102.
[0069]
In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.
