Description

The present invention relates to a filling device and a funnel, and particularly to a technique suitable for use in filling a powder material while manufacturing a packaging bag.

Conventionally, in order to provide fine powders such as coffee, cocoa, matcha, powdered milk, pharmaceuticals, health foods, and powders with poor fluidity (powder materials) as packaging bags for stick type and three-way pouch type, a certain amount is measured. Proposals have been made for fixed-quantity supply packaging machines that supply, supply, and package.

For example, an auger screw type is known as a fixed quantity supply unit that measures a certain amount of powder (powder material) and supplies it to a packaging machine.
As an example of such a configuration, as a multi-row auger weighing type counting accumulation, a vertical auger screw is inserted through a storage hopper and rotated to collect powder stored between the auger screws in the screw portion. It can be supplied downward from the feeding port located at the lower end, and the powder weighed to a certain amount is cut out from the storage hopper according to the rotation amount of the auger screw and supplied so as to be filled in the package bag formed in the shape of a bag. Was there.

Further, the powder material weighed to a certain amount by the auger screw is supplied by a member called a filling chute. The filling chute is composed of a funnel-shaped collector funnel connected to the lower end of the auger screw and a chute portion reduced in diameter by the collector funnel and connected downward (Patent Document 1).

As a stick packaging line, a vertical seal is formed so that the packaging material wraps the chute portion, and a stick-shaped packaging bag is formed. Then, the lower ends of the stick-shaped packaging bag are vertically and horizontally sealed to form a stick-shaped packaging bag. After that, the powder material charged from the inlet portion was put into the packaging bag via the chute pipe, and the upper end of the packaging bag was laterally sealed and sealed (Patent Document 2).

However, when it is sent out from the auger screw, the powder material not only falls into the packaging bag, but also adheres as fine powder to the metal filling chute such as SUS or the like and the chute pipe portion below the auger screw. The adhered powder material accumulates and drops irregularly. When this irregularly dropped powder material enters the packaging bag, there is a problem that an excessive discharge occurs in which a packaging bag having a filling amount different from the fixed amount specified by the auger screw is formed.

Further, when the adhered powder material drops irregularly, the powder raw material passes through the sealing portion or stays in the air as fine powder at the timing of sealing, and is referred to as powder biting into the formed sealing portion. There was a possibility that the seal would be defective.
This powder chewing has a problem that it often occurs when filling health foods such as powdered cocoa beverage, powdered coffee beverage, powdered tea beverage, powdered milk, instant creaming powder, powdered soup, and powdered green juice with poor fluidity. rice field.

The funnel 10 is integrally formed of a flexible material.
As the material for forming the funnel 10, silicon resin, ethylene / propylene / diene rubber (EPDM), nitrile rubber (NBR), chloroprene rubber (CR), and fluororubber can be used. Since the funnel 10 has flexibility, the ease of assembling the funnel 10 can be improved.

The length dimension of the funnel 10 is set corresponding to the vertical position between the lower end portion 114 of the auger and the upper end portion of the foam pipe 151. Specifically, the length dimension of the funnel 10 can be set to be equal to, slightly shorter, or slightly longer than the vertical distance between the lower end portion 114 of the auger and the upper end portion of the foam pipe 151.

Here, when the length dimension of the funnel 10 is set to be slightly longer with respect to the vertical distance between the lower end portion 114 of the auger and the upper end of the foam pipe 151, the funnel 10 is compressed in the vertical direction. By combining these, the upper end of the reduced diameter portion 11 can be pressed against the lower end portion 114 of the auger to bring it into close contact, and the lower end of the uniform diameter portion 12 can be pressed against the upper end of the foam pipe 151 to bring them into close contact with each other. It is possible to minimize the adhesion of powder material and powder material.

Further, here, regardless of whether the length dimension of the funnel 10 is equal to the vertical distance between the lower end portion 114 of the auger and the upper end of the foam pipe 151, which is slightly shorter or slightly longer, the funnel 10 and the auger pipe are used. By making the exhaust function wait at one or more of 112 and the foam pipe 151, the retention of air is further reduced, and the filling performance such as reduction of adhesion due to retention of fine powder and improvement of powder falling speed is further improved. Can be done.
In the length dimension of the funnel 10, a little short or a little long with respect to the vertical distance between the lower end portion 114 of the auger and the upper end of the foam pipe 151 means that there is a dimensional difference of about 1 mm to 5 mm. There is.

The inner diameter at the upper end of the reduced diameter portion 11 and the inner diameter of the lower end portion 114 of the auger are set to be substantially the same, and the inner diameter at the lower end of the uniform diameter portion 12 and the inner diameter at the upper end of the foam pipe 151 are set to be substantially the same.
The inner diameter at the upper end of the reduced diameter portion 11 may be set to be slightly larger than the inner diameter of the lower end portion 114 of the auger, and the inner diameter of the uniform diameter portion 12 may be set to be slightly smaller than the inner diameter of the upper end of the foam pipe 151. can.

Further, on the entire inner surface of the funnel 10, for example, the mold used for molding the silicon resin is made of ABS resin, and the surface roughness of the corresponding portion in this mold is Ra5.30 to 7. It can be set to about 3 μm, preferably about Ra 6.0 to 6.6 μm, and more preferably about 6.3 μm. Since the surface of the ABS resin mold wears as the number of times of use increases, the above numerical values are only the manufacturing conditions within several times after the start of manufacturing. Here, if the surface roughness of the mold surface is made too small, the funnel 10 molded from the mold will not be peeled off, which is not preferable. Further, if the surface roughness of the mold surface is made too large, the powder material tends to stay and adhere, which is not preferable. Further, the inner surface of the funnel 10 is smoothly formed without any unevenness.
The inner surface in the vicinity of the boundary between the reduced diameter portion 11 and the uniform diameter portion 12 is formed so as to be smoothly continuous, so that the powder material is less likely to stay and adhere.
As long as the powder material does not easily stay or adhere, the ABS resin mold surface roughness range as the above manufacturing conditions is not limited to this, and the powder material to be filled and the filling conditions (manufacturing conditions) are not limited. ) Also changes the optimum range, so it is preferable that the inner surface state of the funnel 10 is set according to the conditions of the powder material and the like.

When the powder material is a food product, it is preferable that the funnel 10 is formed so as to comply with the Food Sanitation Law. Alternatively, when the powder material is used as a pharmaceutical product, it is preferable that the funnel 10 is formed by satisfying necessary conditions such as sanitary standards.
In the funnel 10, the reduced diameter portion 11 and the uniform diameter portion 12 can be formed into a so-called straight pipe shape so as to have the same straight axis axis.

The flange portion 13 is provided at the lower end position of the reduced diameter portion 11, and the outer diameter above the flange portion 13 of the funnel 10 is substantially uniform with the outer diameter at the upper end of the reduced diameter portion 11. The outer diameter below the portion 13 is substantially uniform with the outer diameter at the lower end of the uniform diameter portion 12.

The thickness of the flange portion 13 is substantially uniform in the radial direction, but is not particularly limited as long as it can be fixed to the fixing portion 15 described later.
The upper and lower surfaces of the flange portion 13 are set so that the dimensions up to the radial contour differ depending on the outer diameter dimension of the diameter reduction portion 11 and the outer diameter dimension of the diameter equalizing portion 12. Therefore, the wall thickness of the funnel 10 near the lower end of the reduced diameter portion 11 is set to be thicker than that of the other portions.

As shown in FIGS. 3 to 5, the flange portion 13 is sandwiched between the fixing washer plates 14a and 14b from both sides in the vertical direction, is supported in the vertical direction, and is fixed to the fixing portion 15.
The fixed washer plates 14a and 14b are made of metal such as SUS, but are not particularly limited as long as they have rigidity that can fix the funnel 10. Further, the fixed washer plates 14a and 14b are formed in an annular shape with substantially the same radial dimensions as the upper and lower surfaces of the flange portion 13, respectively. The radial dimensions of the fixed washer plates 14a and 14b may be different from those of the upper and lower surfaces of the flange portion 13.

The fixing portion 15 is a horizontal member extending in the horizontal direction substantially orthogonal to the auger pipe 112 at a vertical position between the fixed quantity feeding portion 110 and the filling bag making portion 150.
A plurality of fixed support portions 15a are provided in the fixed portion 15 so that the mounting position can be adjusted. The funnel 10 can be fixed by the fixed support portions 15a, and the vibrating portion 16 is mounted via the support member 15b. Has been done.

The fixed support portion 15a has two arm portions 15a2 and 15a2 protruding in the forward direction (horizontal direction) from the fixed portion 15, and the uniform diameter portion 12 is positioned between the arm portions 15a2 and the arm portions 15a2. At the same time, the flange portion 13 can be positioned by placing the lower fixed washer plate 14b on the upper surface of the two arm portions 15a2. The distance between the two arms 15a2 in the fixed support portion 15a in the left-right direction is set to be equal to or slightly larger than the outer diameter of the uniform diameter portion 12. On the upper surface of the fixed support portion 15a, at least the upper surface of the arm portion thereof is formed in a substantially planar shape so that the fixed washer plate 14b can be placed.

Through holes 13a, 14a1, 14b1, 15a1 are provided in the arm portions 15a2 of the flange portion 13, the fixing washer plates 14a, 14b, and the fixing instruction portion 15a, respectively, and the bolts and nuts 14c, 14d are used as fastening members. By being fastened, the flange portion 13 is fixed to the fixing portion 15.

As shown in FIG. 5, the fixing portion 15 is provided on the machine body 101 so that it can vibrate in the horizontal direction (horizontal direction or front-back direction) intersecting the axial direction of the funnel 10 by the vibrating portion 16. The vibrating portion 16 allows the fixed portion 15 and the funnel 10 fixed to the fixed portion 15 to vibrate in the front-rear direction. The arrows shown in the figure exemplify the vibration direction in the front-back direction.

As shown in FIGS. 3 and 4, the funnel 10 is tightly bound by being covered with a flexible band 18 whose upper end and lower end portion 114 of the auger are connected in a sealed state, and the lower end of the funnel 10 and foam. The upper end of the pipe 151 is covered and tied with a flexible band 19 that connects the periphery in a closed state.

The flexible band 18 has an annular belt shape made of a material having the same flexibility as the funnel 10, and has an inner diameter slightly smaller than the outer diameter of the reduced diameter portion 11 and the lower end portion 114 of the auger.
The flexible band 19 is made of the same material as the funnel 10 and has an inner diameter slightly smaller than the diameter equalizing portion 12 and the outer diameter of the upper end of the foam pipe 151.

The flexible bands 18 and 19 have flexibility and inner diameter dimensions to which a reduced diameter portion 11, an auger lower end portion 114, a diameter equalizing portion 12 and a foam pipe 151 are fitted so that they can be hermetically connected to each other.
The thickness and width dimensions of the flexible bands 18 and 19 are not particularly limited, but are set as the thickness and width dimensions having the strength to maintain the sealed state because the vibration by the vibrating portion 16 is applied. Is preferable.

In the filling device 100 in the present embodiment, the powder material sent out as a constant amount from the lower end portion 114 of the auger of the fixed quantity feeding unit 110 falls to the reduced diameter portion 11 of the funnel 10 vibrating in the horizontal direction by the vibrating unit 16. , Moves through the diameter equalizing portion 12 to the foam pipe 151 of the filling bag making portion 150.

At this time, since the flexible bands 18 and 19 are sealed, the leakage of the powder material to the outside is suppressed over the lower end portion 114 of the auger, the funnel 10 and the foam pipe 151.

Further, the upper end of the reduced diameter portion 11 and the lower end portion 114 of the auger, and the uniform diameter portion 12 and the upper end of the foam pipe 151 are connected to each other so as to be in contact with each other or close to each other with an interval of about 1 to 5 mm. It is possible to prevent or minimize the formation of irregularities on the inside of the surface, thereby preventing the powder material from entering the formed irregularities and causing irregular drops. In particular, it is possible to prevent the powder material from adhering to the funnel 10 and the foam pipe 151, which are located below the connection portion.

Further, since the upper end of the reduced diameter portion 11 and the lower end portion 114 of the auger, and the uniform diameter portion 12 and the upper end of the foam pipe 151 are connected so as to be in contact with each other, the funnel 10 itself can be compared with the conventional metal funnel. The size can be reduced, and as a result, the area of the inner surface of the funnel 10 to which the powder material adheres can be reduced, and the amount of the powder material to which the powder material adheres can be further reduced.

Further, since the funnel 10 having flexibility and being made smaller and lighter is configured to be vibrated in the horizontal direction by the vibrating portion 16, the fixed portion 15 and the funnel 10 do not vibrate in the vertical direction, so that the diameter-reduced portion is formed. The upper end of the auger 11 and the lower end 114 of the auger, the lower end of the uniform diameter portion 12 and the upper end of the foam pipe 151 can be brought into close contact with each other, and it is not necessary to form unevenness inside the connection portion as a vibrating gap. At the same time, when it is attempted to apply the same vibration, the output of the required vibration unit 16 can be made smaller than that of the metal funnel.

Here, if unevenness is formed inside the connection portion between the upper end of the reduced diameter portion 11 and the lower end portion 114 of the auger, and the smoothed diameter portion 12 and the upper end of the foam pipe 151, the powder material or this powder is formed in the concave portion. The gas mixed in the material stagnates and stays, resulting in the accumulation of the powder material. On the other hand, in the present embodiment, since such a recess is not formed, it is possible to prevent the occurrence of retention in the recess, and the occurrence of irregular drop in which the powder material suddenly adhered / retained falls. Can be prevented extremely effectively.

Further, the funnel 10 of the present embodiment is formed of a silicon resin or the like, and the inner surface of the funnel 10 is formed so as to be within the range of the above-mentioned inner surface roughness, so that the powder adheres to the inner surface of the funnel 10. The material can be extremely reduced.
Further, by vibrating the funnel 10 in which the adhesion of the powder material is minimized by the vibrating portion 16, the powder material can be effectively dropped from the inner surface of the funnel 10 deformed by the vibration, and the powder material is suddenly adhered. It is possible to extremely effectively prevent the occurrence of irregular drops of the powder material.

As a result, even if the powder material is a health food such as powdered cocoa beverage, powdered coffee beverage, powdered tea beverage, instant creaming powder, powdered milk, powdered soup, powdered green juice, etc., which has poor fluidity and easily adheres, it cannot be used. It is possible to prevent the occurrence of regular drops, prevent the occurrence of excessive discharge and powder biting, and prevent the yield from decreasing in the production of the stick packaging bag P.

Further, since the funnel 10 of the present embodiment is formed of a flexible silicon resin or the like, the funnel 10 can be easily deformed, so that the upper end of the reduced diameter portion 11 and the lower end of the auger 114, and At the time of assembling the lower end of the diameter equalizing portion 12 and the upper end of the foam pipe 151, the stick-shaped packaging bag P can be obtained by simply fitting the funnel 10 with the flexible bands 18 and 19 in a state where the funnel 10 is easily deformed and abutted against each other. It can be assembled in a manufacturable sealed state. The required deformation of the funnel 10 at the time of assembly is about 5 mm, and the funnel 10 formed of silicon resin or the like can sufficiently cope with it.

As a result, conventionally, at the time of assembly, a large number of fixed support portions 15a are aligned with respect to the fixed portion 15, and a large number of funnels made of metal that are not easily deformed are provided with the fixed support portion 15a and the lower end of the auger. A large number of processes such as three-dimensionally accurate alignment of the portion 114 and the upper end of the foam pipe 151 are required, and in each process, the bolts and nuts and the like are loosened and then fastened. It is possible to perform the positioning / assembling process with poor handleability, which has been performed sequentially, without using a fastening tool or a positioning tool.

Further, as compared with the metal funnel such as stainless steel, in the present embodiment, the funnel 10 is made of silicon resin, so that the weight can be reduced and the handleability at the time of cleaning and assembling can be improved.
Further, since the flexible funnel 10 is deformed and the adhered powder material can be easily sucked, it is not necessary to remove it from the fixing portion 15, so that the handling property at the time of cleaning and assembling is improved. The working time can be shortened.

Further, the fixed support portion 15a has two arm portions 15a2, and the funnel 10 can be set only by the horizontal operation of locating the uniform diameter portion 12 between the arm portions 15a2 and the arm portions 15a2. Therefore, it is not necessary to remove the fixed portion 15 itself from the machine body 101, the labor is not required at the time of assembly, the handleability is improved, and the labor and time required for maintenance can be shortened.

Therefore, even in the multi-row auger weighing type filling device 100 having a large number of auger pipes 112, it is possible to easily assemble the vicinity of the funnel 10 in a short time, and the handling property is improved. It is possible to reduce the labor and time required for maintenance.

Further, in the cleaning step of the funnel 10, it is possible to remove the adhered powder material only by deforming the funnel 10, and even in the multi-row auger weighing type filling device 100 having a large number of auger pipes 112. , It is possible to reduce the labor and time required for cleaning.

In addition, in this embodiment, in FIGS. The inclination angle thereof can be appropriately set corresponding to the horizontal position of 114 and the foam pipe 151. Specifically, it is also possible to configure the axis of the reduced diameter portion 11 and the axis of the uniform diameter portion 12 to coincide with each other.

Hereinafter, a second embodiment of the filling device according to the present invention will be described with reference to the drawings.
FIG. 6 is an enlarged cross-sectional view showing the vicinity of the funnel in the filling device in the present embodiment, and what is different from the above-mentioned first embodiment in the present embodiment is the point regarding the adhesion detection unit, and the other points described above. The same reference numerals are given to the configurations corresponding to the first embodiment, and the description thereof will be omitted.

In the filling device 100 of the present embodiment, as shown in FIG. 6, adhesion detection units 20 are provided in the vicinity of a large number of funnels 10, respectively.
The adhesion detection unit 20 includes a detection light irradiation unit 21 and a detection unit 22, and the detection light irradiation unit 21 and the detection unit 22 are arranged so as to be radially symmetrical positions with respect to the axis of the funnel 10. There is.

At the same time, the funnel 10 is made of a material that is flexible and capable of transmitting detection light, and examples thereof include uncolored silicon resin.

The arrangement of the detection light irradiation unit 21 and the detection unit 22 is not limited to this arrangement as long as the adhesion state of the powder material in the funnel 10 can be detected, as will be described later. For example, the detection light irradiation unit 21 can be arranged so as to pass through a predetermined position on the inner surface of the reduced diameter portion 11, and the detection unit 22 can be arranged so that the detection light transmitted through the portion can be detected.

Further, the detection light irradiation unit 21 and the detection unit 22 can be arranged so that the adhered state of the powder material can be detected on the diameter equalizing portion 12. In this case, for example, when an irregular drop occurs, it can be detected.

The detection light irradiation unit 21 irradiates a type of detection light that can transmit a funnel 10 made of silicon resin or the like, such as visible light, infrared light, and ultraviolet light, and can detect the state of the attached powder material. It is considered possible. Specifically, a laser light oscillating device that irradiates a laser beam capable of detecting this state change can be exemplified according to the composition, color, particle size, density, and the like of the powder material.

The detection unit 22 is a sensor that can detect the state of the powder material by detecting the detection light emitted from the detection light irradiation unit 21. For example, it is possible to detect the laser beam and make it possible to detect the adhered state of the powder material by its intensity.

In the present embodiment, when the packaging bag P is manufactured, the detection light is irradiated from the detection light irradiation unit 21, the funnel 10 is transmitted therethrough, and the intensity is measured by the detection unit 22.
If the powder material does not adhere to the funnel 10, or if the degree of adhesion does not cause irregular drops, the strength measured by the detection unit 22 is sufficiently strong. It can be seen that there is no need to do anything and the production of the packaging bag P can be continued as it is.

Further, when the powder material adhered to the funnel 10 and the degree of adhesion increased to the extent that irregular drops occurred, the detection light transmitted by the powder material decreased and was measured by the detection unit 22. The detection light intensity becomes weak. As a result, it becomes possible to detect that the powder material is attached in excess of the specified value, and the powder supply is interrupted due to the rotation stop of the auger screw, the production of the packaging bag P is interrupted, or in addition, the funnel 10 is used. It is possible to perform necessary processing such as cleaning.

This reliably detects the possibility of irregular drops or the occurrence of irregular drops, reliably prevents the occurrence of excessive discharge and powder biting, and avoids a decrease in yield in the production of stick-shaped packaging bag P. It becomes possible to do.

Further, in the first and second embodiments described above, when the packaging bag P is manufactured and filled, the detection light is irradiated from the non-fixed detection light irradiation unit 21 to allow the funnel 10 to pass through the inside of the funnel 10. You can also observe the condition. In this case, the detection light irradiation unit can be used as an LED light on hand by the worker, and the heat seal and the filling timing can be adjusted.

Hereinafter, examples of the present invention will be described.

Here, the stick-shaped packaging bag P is manufactured by using the funnel 10 made of silicon resin in an actual manufacturing apparatus, and the number of stick-shaped packaging bags that have been excessively discharged and the stick-shaped packaging bag that has become powder-bitten. The number of pieces was verified as the over-emission rate and the powder biting rate, which are the ratios of the number of pieces manufactured to the total number of pieces.
At the same time, we compared the incidence of overdose and powder biting when using a conventional stainless steel funnel. Stick-shaped packaging bag P Shows the specifications for manufacturing.

Filling amount in packaging bag: The following 4 types (ratio of the corresponding number to the total number of manufactured products)

10g (34.8%),
12g (52%)

・ Silicon funnel Filled powder material: Coffee, etc. (96.0% with sugar, 4.0% without sugar)
Number of packaging bags manufactured: Approximately 50,000,000 in total Overdose discharge rate: 8.9ppm

Number of packaging bags manufactured: Approximately 30,000,000 in total Powder biting rate: 0.06ppm

-Stainless steel funnel filled powder material: coffee, etc. (93.3% with sugar, 8.7% without sugar)
Number of packaging bags manufactured: Approximately 40,000,000 in total Overdose discharge rate: 238.0 ppm

Number of packaging bags manufactured: Approximately 20,000,000 in total Powder biting rate: 9.56ppm

From the above results, the filling device 100 having the funnel 10 of the present invention reduces the adhesion of the powder material having poor fluidity, prevents the adhered powder material from occurring irregularly, and causes an excessive amount. It can be seen that the occurrence of discharge and powder biting can be prevented.

In addition, in order to verify the handleability and the reduction of labor and time required for maintenance, the cleaning and assembly time during maintenance was measured.
10 funnels of multi-row auger weighing type filling device 100 Number of pieces: 10 Cleaning method; Remove the funnels and remove the adhered powder material by suction.
・ Silicon funnel assembly time after disassembly: 1.2 hours ・ Stainless steel funnel assembly time after disassembly: 3.8 hours

From the above results, it can be seen that the filling device 100 having the funnel 10 of the present invention can shorten the assembly time during maintenance.

As an example of utilization of the present invention, a stick type or a three-way pouch can be used for health foods such as powdered cocoa beverages, powdered coffee beverages, powdered tea beverages, instant creaming powders, powdered milk, powdered soups, powdered green juices, and powders such as powdered pharmaceuticals. Examples include the use in a device for filling a certain amount in a packaging bag such as a type and a gusset pack, a plastic or glass bottle container, and the like.
