Description
Technical Field
The present invention relates to a filling device for filling a container with contents, and more particularly to a filling device for filling a container with viscous contents.
Background
Conventionally, as a filling apparatus for filling a container with viscous contents such as meat processed products, a filling apparatus 110 is known, and as shown in fig. 4, the filling apparatus 110 includes: a filling nozzle 120 having a nozzle hole 123 formed in the vertical direction and opening downward; a content supply unit 130 that supplies a content to the nozzle hole 123; and a plunger 140 disposed in the nozzle hole 123 so as to be movable up and down (see, for example, patent document 1).
In the filling device 110, a predetermined amount of contents is supplied to the nozzle hole 123 by the content supply means 130, and the contents in the nozzle hole 123 are pushed out downward by the plunger 140, whereby the contents are filled into the container C.
However, in the filling device 110, since the nozzle tip (lower end) of the filling nozzle 120 is in close contact with the upper surface of the content immediately after the container C is filled with the content, when the nozzle tip is separated from the content from this state, the center portion of the upper surface of the content in close contact with the nozzle tip is pulled upward, and a so-called convex horn (horn) is formed on the upper surface of the content.
Further, when the container C is sealed with the lid while the convex horn is formed on the upper surface of the content, the convex horn is crushed by the lid and adheres to the back surface of the lid, which causes a problem that the appearance is deteriorated when the container is opened, and there is another problem that: the contents crushed by the lid may adhere to the container flange portion C1, and a sealing failure of the lid may occur.
Therefore, in the filling device 110 of patent document 1, in order to eliminate the state where the content adheres to the nozzle tip, as shown in fig. 4, an annular gas ejection port 129 is formed at the tip (lower end) of the plunger 140, and the content is filled and then the gas is ejected from the gas ejection port 129, thereby separating the content from the nozzle tip.

Patent document 1: japanese Kokai publication Hei-5-37094
Disclosure of Invention
However, in the filling device 110 of patent document 1, since the gas discharge port 129 and the gas flow path 127 are formed in the plunger 140 that moves up and down, the gas supply unit 150 that supplies gas to the gas flow path 127 (or a connection pipe that connects the gas supply unit 150 and the gas flow path 127) must move up and down in accordance with the up and down movement of the plunger 140, and as a result, there is a problem as follows: the device structure becomes complicated and the degree of freedom in design of the surrounding environment is impaired.
In the filling device 110 of patent document 1, when the annular gas discharge port 129 is formed at the distal end of the plunger 140, the food adhesion preventing member 190 formed by complicated processing is attached to the concave portion formed at the distal end of the plunger 140, but if the annular gas discharge port 129 is formed at the distal end of the plunger 140 in this way, complicated processing is required to be performed on the distal end of the plunger 140, which causes a problem of an increase in manufacturing load.
Further, particularly in the case of viscous contents, there is a problem that it is difficult to fill the contents uniformly into the corners of the container C without any gap, and if the filled contents are not uniformly filled into the container C, the contents may be deteriorated due to the gap, and if the contents are not uniformly filled into the container C, the contents may be adhered to the container flange portion C1 and sandwiched between the container and the lid, thereby deteriorating the sealing property.
Accordingly, in order to solve the above-described problems, an object of the present invention is to provide a filling device which can prevent uneven filling of a container or a horn protruding from the upper surface of the filled content while achieving simplification of the device structure, improvement of the degree of freedom in design, and reduction of the manufacturing load.
The present invention provides a filling device, comprising: a filling nozzle having a nozzle hole formed in a vertical direction and opening downward; a content supply unit which supplies a content to the nozzle hole; a plunger which is disposed in the nozzle hole so as to be movable up and down, and which pushes out a content supplied into the nozzle hole downward; and a gas supply unit for supplying a gas, wherein the filling nozzle is provided with: a gas inlet connected to the gas supply unit; a gas flow outlet opening to the nozzle hole; and a gas flow passage that communicates the gas inlet and the gas outlet, and that discharges the gas supplied from the gas supply means from a gap between an inner circumferential surface of the nozzle hole and an outer circumferential surface of the plunger at a lower end of the filling nozzle.
Effects of the invention
According to the invention of claim 1, the gas is ejected from the nozzle tip of the filling nozzle, so that the gas can be fed in a ring shape between the nozzle tip of the filling nozzle and the upper surface of the contents after the contents are filled, the close contact between the nozzle tip and the contents can be released, and the formation of a convex horn on the upper surface of the contents can be prevented.
That is, according to the invention of claim 1, since the gas flow passage is formed in the filling nozzle and the gap between the inner peripheral surface of the nozzle hole and the outer peripheral surface of the plunger is used as the gas ejection port for ejecting the gas from the nozzle tip, unlike the conventional filling device in which the gas flow passage and the gas ejection port are formed in the plunger that moves up and down, it is not necessary to move up and down the gas supply unit, the connection pipe, and the like connected to the gas flow passage in accordance with the up and down movement of the plunger, and therefore, the device structure can be simplified and the degree of freedom in designing the surrounding environment can be increased.
Further, since the gap between the inner peripheral surface of the nozzle hole and the outer peripheral surface of the plunger is used as the gas ejection port, it is not necessary to form a separate gas ejection port, and the manufacturing load can be reduced.
Further, since the gap between the inner peripheral surface of the nozzle hole and the outer peripheral surface of the plunger is used as the gas ejection port, even when the gas ejection port is clogged with the content, the content can be removed by moving the plunger up and down, and therefore, the clogging of the content in the gas ejection port can be easily and reliably eliminated without a special operation.
According to the invention of claim 2, the filling nozzle includes: a nozzle body; and a nozzle tip attached to the lower side of the nozzle body, whereby the nozzle tip can be replaced according to the type of contents and the shape of the container, and the contents can be uniformly filled into each corner of the container without any gap.
According to the invention of claim 3, since the annular first packing is provided on the outer peripheral side of the opening formed on the facing surface of the nozzle body between the facing surfaces of the nozzle body and the nozzle tip, the gas supplied from the gas supply means can be prevented from leaking to a portion other than the predetermined flow path, and therefore, the gas can be efficiently sent between the content and the lower end of the filling nozzle. Further, by interposing the first packing between the facing surfaces of the nozzle body and the nozzle tip, a gap between the facing surfaces of the nozzle body and the nozzle tip, which are used as a part of the gas flow passage and the gas outflow port, can be maintained at an appropriate width. Further, since the annular recess formed in an annular shape and communicating with the opening of the facing surface is provided on the outer peripheral side of the nozzle hole in at least one of the facing surfaces of the nozzle body and the nozzle tip, the gas can be circulated between the facing surfaces of the nozzle body and the nozzle tip in an annular shape, and therefore, the gas can be uniformly discharged from the annular gap between the outer peripheral surface of the plunger and the inner peripheral surface of the nozzle hole at the nozzle tip.
According to the invention of claim 4, since the annular second packing is disposed above the content supply hole connected to the content supply means between the inner peripheral surface of the nozzle hole and the outer peripheral surface of the plunger, the gas supplied from the gas supply means can be prevented from leaking to a portion other than the predetermined flow path, and therefore, the gas can be efficiently sent between the content and the lower end of the filling nozzle.
According to the invention of claim 5, since the nozzle cover which is movable in the vertical direction is provided on the outer periphery of the filling nozzle, when the contents are filled, the outer peripheral edge portion of the upper surface of the contents is pressed by the nozzle cover on the outer peripheral side of the filling nozzle, whereby adhesion of the filled contents to the flange portion of the container and flattening of the upper surface can be prevented, and furthermore, by forming the gas inlet at a position above the uppermost nozzle cover, interference between the nozzle cover and a connection pipe connected to the gas inlet can be prevented.
According to the invention of claim 6, since the center portion of the front end convex portion is formed to protrude downward on the lower surface of the filling nozzle, the center portion of the upper surface of the content filled in the container can be depressed, and therefore the upper surface of the content after heat sterilization can be flattened. That is, in the case where the content is a processed meat product or the like, the content expands when the content is heat-sterilized after being filled in the container, but by recessing the center portion of the upper surface of the content in advance in consideration of the expansion of the content, the upper surface of the heat-sterilized content can be flattened.

Detailed Description
Hereinafter, a filling device 10 according to an embodiment of the present invention will be described with reference to the drawings.
The filling device 10 fills a container C with viscous contents B such as meat processed products, and as shown in fig. 1, the filling device 10 includes: a filling nozzle 20 having a nozzle hole 23; a content supply unit 30 for supplying the content B to the nozzle hole 23; a plunger 40 which is disposed in the nozzle hole 23 so as to be movable up and down and which pushes out the content B supplied into the nozzle hole 23 downward; a gas supply unit 50 that supplies gas a; a nozzle cover 60 provided on the outer periphery of the filling nozzle 20; a first gasket 70 and a second gasket 71 in the form of rings, which seal the respective portions; and a container lifter 80 that moves the container C up and down.
Hereinafter, each component of the filling device 10 will be described with reference to fig. 1 to 3.
First, as shown in fig. 1 and 2, the filling nozzle 20 includes: a cylindrical nozzle hole 23 extending in the vertical direction and opening downward; and a content supply hole 24 extending from the nozzle hole 23 toward the side and reaching the outer surface of the filling nozzle 20. The content supply hole 24 is connected to the content supply unit 30 and supplies the content B into the nozzle hole 23.
The filling nozzle 20 is formed with a flow path for ejecting the gas a supplied from the gas supply unit 50 from the nozzle tip (lower end) of the filling nozzle 20, and specifically, as shown in fig. 1 and 2, formed with: a gas inlet 25 which is opened to the outer surface of the filling nozzle 20 and is connected to the gas supply unit 50; a gas outlet 26 that opens into the nozzle hole 23; and a gas flow path 27 that communicates the gas inlet 25 and the gas outlet 26.
As shown in fig. 2, the gas a supplied from the gas supply unit 50 is ejected into the nozzle hole 23 through the gas inlet 25, the gas flow passage 27, the annular recess 21a, and the gas outlet 26, and is ejected from the annular gap between the outer circumferential surface of the plunger 40 and the inner circumferential surface of the nozzle hole 23, which are moved downward, at the nozzle tip of the filling nozzle 20.
Further, describing the filling nozzle 20 in more detail, as shown in fig. 1 and 2, the filling nozzle 20 includes: a nozzle body 21; and a nozzle tip 22 attached to the lower side of the nozzle body 21 in a fixed state.
As shown in fig. 2, the nozzle body 21 includes: the aforementioned gas inflow port 25; an opposite surface side opening 28 that opens to an opposite surface (lower surface) of the nozzle body 21 that is opposite to the upper surface of the nozzle tip 22; and a body flow passage 29 that communicates the gas inlet 25 with the opposite-surface-side opening 28.
In the present embodiment, the gas flow path 27 includes: a body flow passage 29; the opposite side is open 28; and a gap between the opposed surfaces of the nozzle body 21 and the nozzle tip 22.
The gas outlet 26 is formed by a gap between the facing surfaces of the nozzle body 21 and the nozzle tip 22.
The nozzle holes 23 are formed in both the upper nozzle body 21 and the lower nozzle tip 22, and open to the lower surface of the nozzle tip 22.
An annular recess 21a communicating with the facing surface side opening 28 is formed in the facing surface (lower surface) of the nozzle body 21. Similarly, an annular recess communicating with the facing-surface-side opening 28 may be formed in the facing surface (upper surface) of the nozzle tip 22.
As described above, since the annular concave portion 21a is formed on at least one of the opposing surface (lower surface) of the nozzle body 21 and the opposing surface (upper surface) of the nozzle tip 22, the gas a can be circulated between the opposing surfaces of the nozzle body 21 and the nozzle tip 22 in an annular shape, and therefore, the gas a can be uniformly discharged from the annular gap between the outer peripheral surface of the plunger 40 and the inner peripheral surface of the nozzle hole 23 at the nozzle tip of the filling nozzle 20.
As shown in fig. 3, the nozzle tip 22 is formed in an approximately rectangular shape similar to the shape of the container C when viewed from below. The shape of nozzle tip 22 may be designed according to the shape of container C and the opening thereof. By forming the container C and the nozzle tip 22 in the same shape as described above, the contents B can be flowed to each corner of the container C using the nozzle tip 22 as a pressing plate, and the viscous contents B can be filled in the container C, particularly in the corner of the bottom of the container C, without forming a space.
As shown in fig. 1 to 3, a tip protrusion 22a is formed on the lower surface of the nozzle tip 22 (filling nozzle 20), and the center of the tip protrusion 22a protrudes downward. By filling the inside of the bag so that the front end convex portion 22a is formed and the surface of the content B is dented, the surface of the content B can be smoothed even if the viscous content B swells in the sterilization bag.
The content supply unit 30 supplies a fixed amount of the content B to the nozzle hole 23, and is configured by a measuring instrument, a cylinder, and the like. As shown in fig. 1, the content supply unit 30 is connected to the content supply hole 24 of the filling nozzle 20 through a content supply pipe 31 attached to the filling nozzle 20.
As shown in fig. 1, the plunger 40 is a substantially columnar member that moves up and down by a plunger driving unit 41 configured by an air cylinder or the like. When moving downward, as shown in fig. 2, the lower surface of the plunger 40 is substantially flush with the lower surface of the tip end protrusion 22a of the nozzle tip 22 in a state where the plunger 40 is moved to the lowermost position.
The gas supply unit 50 is for supplying the gas a, and in the present embodiment, the gas supply unit 50 includes the following components: an air compressor including a regulator for adjusting a supply amount of compressed air; and a filter that purifies air supplied from the air compressor. The specific embodiment of the gas supply unit 50 may be any one as long as the gas a such as air can be supplied.
The nozzle cover 60 is configured to: the filling nozzle 20 is movable in the vertical direction and abuts against the container stacking portion C2, and when the content B is filled, the outer peripheral edge portion of the upper surface of the content B is pressed against the outer peripheral side of the filling nozzle 20, whereby the filled content B is prevented from adhering to the container flange portion and the upper surface is flattened. The nozzle cover 60 is biased downward by a spring (not shown). As shown in fig. 2, the lower surface of nozzle cover 60 is substantially flush with the lower surface of the outer peripheral portion of tip end protrusion 22a of nozzle tip 22 in the state where nozzle cover 60 is positioned at the lowest position.
As shown in fig. 1 and 2, the first gasket 70 is disposed between the facing surfaces of the nozzle body 21 and the nozzle tip 22 on the outer peripheral side of the facing surface side opening 28. More specifically, the first gasket 70 is disposed in an annular recess formed in the opposite surface (upper surface) of the nozzle tip 22. Thereby, the gas a can be controlled to: flows only in the direction of the gas outflow port 26 without leaking in the outer circumferential direction of the filling nozzle 20.
As shown in fig. 1 and 2, the second gasket 71 is disposed between the inner peripheral surface of the nozzle hole 23 and the outer peripheral surface of the plunger 40 above the content supply hole 24. More specifically, the second gasket 71 is disposed in an annular recess formed in the outer peripheral surface of the plunger 40. Thereby, the gas a can be controlled to: flows only in the direction of the filling nozzle 20 and does not leak from above the plunger 40.
The container lifter 80 moves up and down, and moves the container C at the lower side of the filling nozzle 20 in accordance with the filling of the content B. In the present embodiment, the filling nozzle 20 is set in a fixed state, but the filling nozzle 20 may be configured to move up and down, or both the filling nozzle 20 and the container C may be configured to move up and down. In this way, by synchronizing the moving speed of the container lifter 80 or the filling nozzle 20 with the filling speed of the content B, the content B can be made to flow to each corner of the container C, and even in the case of the content B containing a viscous or sheet-like solid material, the formation of a gap between the contents can be prevented.
Next, a method of filling the container C with the content B using the filling device 10 will be described below.
First, the container C is moved upward by the container lifter 80 so that the nozzle cover 60 on the outer periphery of the filling nozzle 20 abuts on the container stacking portion C2 of the container C, and the nozzle tip 22 of the filling nozzle 20 is inserted into the vicinity of the lower end in the container C.
At this time, the nozzle cover 60 is pushed upward by the container stacking portion C2 and moved upward.
Next, in a state where the container lifter 80 is stopped, the supply of the content B into the nozzle hole 23 from the content supply unit 30 through the content supply hole 24 is started, and after the content B is filled into each corner of the bottom of the container C without a gap (after about 10 seconds), the supply of the content B is continued while the container C is moved downward by the container lifter 80. The time for stopping the container lifter 80 and the lowering distance of the container lifter 80 may be appropriately adjusted according to the filling speed of the container C and the content B. Then, the supply of the content B is stopped at a stage when the outer peripheral edge of the nozzle tip 22 and the nozzle cover 60 are in a substantially flush position, the container lifter 80 is further lowered by several mm (about 3mm in the present embodiment), and then the plunger 40 is moved downward to press the content B in the nozzle hole 23 into the container C, thereby completing the filling. In this way, by adjusting the lowering timing of the container lifter 80 in several stages, it is possible to further prevent uneven filling into the container C and generation of a gap in the content B.
In this filled state, as shown in fig. 2, the content B in the container C is in close contact with the lower surface of the filling nozzle 20 (nozzle tip 22), that is, the space between the upper surface of the content B and the lower surface of the filling nozzle 20 is in a vacuum state.
Then, as shown in fig. 2, the gas a is supplied from the gas supply unit 50, and is fed between the upper surface of the content B and the lower surface of the filling nozzle 20 through the gas inlet 25, the gas flow passage 27, the gas outlet 26, the annular recess 21a, and the annular gap between the outer peripheral surface of the plunger 40 and the inner peripheral surface of the nozzle hole 23. This makes it possible to release the vacuum state between the upper surface of the content B and the lower surface of the filling nozzle 20, to release the state in which the upper surface of the content B is in close contact with the lower surface of the filling nozzle 20, and to prevent the formation of a convex horn when the filling nozzle 20 pulls up the upper surface of the content B after the content B is filled and the container C is separated from the filling nozzle 20.
Finally, the container C filled with the content B is moved downward.
The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments described above, and various design changes may be made without departing from the scope of the present invention described in the claims.
For example, in the above-described embodiment, the structure including the nozzle body and the nozzle tip has been described as the filling nozzle, but the filling nozzle may be formed as a single member.
