Description

The present invention relates to a cut-out weighing device and a cut-out weighing method.

In the past, a cutting device for cutting out a weight to be weighed using a screw blade provided up to the vicinity of the outlet of the cylinder so as to communicate from the hopper to the inside of the cylinder was known (see Patent Documents 1-3). The screw blades were provided to communicate with the inside of the cylinder, which was merely a passive passage from the hopper to the outside.

In addition, a drying tool equipped with a weighing mechanism that weighs and cuts out drying ingredients (powder and granules such as ochazuke, sprinkle, or cup ramen bag) and a packaging mechanism that wraps the drying ingredients cut out by the weighing mechanism. A material bagging device is known (see, for example, Patent Document 4).

The present inventors have improved hygiene by making it possible to easily remove the cutout pipe that rotates the cylinder after taking in the weighed object and actively cuts out the weighed object. We have developed and provided a cutting-out weighing device and the like (see, for example, Patent Document 5).

Conventionally, the uptake from the hopper to the cutout pipe has been promoted by forming the tip of the cutout pipe into a blade shape.

Japanese Patent No. 2774593 Special Publication No. 43-14537 China Practical New Patent No. 20248967 Japanese Unexamined Patent Publication No. 2004-314983 Japanese Patent No. 64033348

In the first place, the old-fashioned cutting device as described in Patent Document 3-5 has a big drawback that the weight to be weighed such as powder easily sticks to the cylinder and becomes unsanitary. Therefore, in recent years, a cutout pipe method with improved hygiene is often adopted.

However, it has been difficult for the conventional cutting and weighing devices described in Patent Documents 4 and 5 to take in easily entangled vegetables such as leaves. In addition, for materials such as soup powder and other materials that tend to blitch (stick) to the inner wall of the hopper due to the moisture in the air, such as soup powder, the cutout pipe can also be used for materials in which the sugar content of the material components melts and the materials tend to solidify and become lumpy. It was difficult to capture.

Therefore, an object of the present invention is to provide a cut-out weighing device or the like that facilitates taking in a leaf or a easily meltable material from a hopper into a cutout pipe.

The first aspect of the present invention is a cutting-out weighing device that cuts out a weighing object, and a cylindrical cut-out pipe that rotates the cylinder itself after taking in the weighing object and actively cuts out the weighing object. A hopper that supplies the weighed object to the cutout pipe, and a movable guiding member that actively guides the weighed object in the hopper into the cutout pipe. The inside of the hopper communicates with the hopper, and the movable guide member is a cut-out weighing device penetrating the communication portion.

The second aspect of the present invention is the cut-out weighing device of the first aspect, in which the movable guide member is not inserted up to the discharge end of the cutout pipe for discharging the weighed object.

A third aspect of the present invention is the cut-out weighing device according to the first or second aspect, wherein the movable guide member includes an axial center extending in the long axis direction of the cutout pipe and the circumference of the axial center. It has a spiral screw blade, and further includes a guide member control unit that rotates the screw blade around the axis.

The fourth aspect of the present invention is the cutting and weighing device of the third aspect, and the pitch of the screw blades is the same at a plurality of places.

The fifth aspect of the present invention is the cut-out weighing device according to the third or fourth aspect, in which the diameter of the screw blade around the axis is substantially equal to the inner diameter of the cutout pipe. be.

A sixth aspect of the present invention is a cutting-out weighing method using a cutting-out weighing device that cuts out a weighing object, in which the weighing device rotates the cylinder itself after taking in the weighing object to rotate the weighing object. A cylindrical cutout pipe that actively cuts out, a hopper that supplies the weighed object to the cutout pipe, and a movable that actively guides the weighed object in the hopper into the cutout pipe. The cutout pipe and the hopper are internally communicated with each other in a communication portion, the movable guide member penetrates the communication portion, and the movable guide member is located in the hopper. It is a cut-out weighing method including a guidance step of guiding the weighed object to the cutout pipe and a cutting-out step in which the cutout pipe cuts out the weighed object.

According to each viewpoint of the present invention, whether the weight to be weighed in the hopper is powdery or a material that is easily entangled such as leafy vegetables, a material that easily melts and sticks, a certain size such as wonton. Even with the same material, the movable guide member can be reliably (forced) squeezed into the inside of the cutout pipe through the communication portion. As a result, the intake into the cutout pipe is stabilized, so that the weighing capacity and the weighing accuracy can be improved.

Until now, the cutout pipe can be cut out by rotating the cutout pipe as long as the weight to be weighed in the hopper enters the cutout pipe by its own weight when cutting out the powdered weight to be weighed. rice field. Therefore, it was not necessary to actively (force) guide the weight to be weighed from the hopper to the inside of the cutout pipe. In this respect, the technical background that is a prerequisite for the old-fashioned cutting device in which the cylinder does not rotate is completely different.

Nevertheless, the inventor of the present application has provided a movable guide member that penetrates the communication portion in order to solve the new technical problem of reliably incorporating a material other than the powdery weight to be weighed, which is well dried and easy to handle, into the cutout pipe. It is provided.

Further, according to the second aspect of the present invention, the movable guide member only needs to have a length that penetrates the communication portion. In this respect, it can be said that the old-fashioned cutting device and the cutting device according to the present invention, which require a movable guide member such as a screw blade to the discharge end of the cylinder because the cylinder does not rotate, are different in configuration.

For example, when the screw as a movable guide member extends to the discharge end of the cutout pipe, it is always cut out by the pitch of the screw. Therefore, according to the second aspect of the present invention, since the movable guide member is only in the middle of the cutout pipe, it is possible to individually control the intake from the hopper to the cutout pipe and the cutout from the cutout pipe. It will be possible.

Further, according to the third aspect of the present invention, it becomes easy to take the object to be weighed into the cutout pipe and cut it out in a plurality of patterns regarding the size and pitch of the screw blades.

Further, according to the third aspect of the present invention, it becomes easy to control the uptake from the hopper to the cutout pipe, and it becomes easy to stably take in a desired amount of the weight to be weighed at a desired timing. .. Therefore, it becomes easy to stably cut out a desired amount of the object to be weighed at a desired timing.

Here, when a weighted object, particularly a raw material that easily adheres to the cutout pipe, is sent to the cutout pipe, the weighted object may adhere to the inner surface of the cutout pipe. In the conventional cutting and weighing device, the adhesion has been improved by a mechanism such as a scraper of another mechanism, but it is not sufficient, and it is necessary to clean the cutout pipe every 1 to 2 hours.

Therefore, according to the fourth aspect of the present invention, the deposits on the inner surface of the cutout pipe are screwed by rotating the screw blades inside the cutout pipe, particularly whether or not the screw blades are in contact with the inner surface of the cutout pipe. The blades can be scraped off. This always refreshes the inner surface of the cutout pipe. Therefore, since the cleaning time of the cutout pipe is reduced, stable cutting becomes easy without stopping the cutting and weighing device.

It is a figure which shows the outline of the cut-out weighing apparatus which concerns on embodiment of this invention. It is a figure which looked at the cut-out weighing apparatus of FIG. 1 from the top. It is a figure which shows an example of a screw.

Hereinafter, examples of the present invention will be described with reference to the drawings. The embodiment of the present invention is not limited to the following examples.

1A and 1B are views showing an outline of a cut-out weighing device according to an embodiment of the present invention (an example of the “cut-out weighing device” described in the present invention), where FIG. 1A is a front view and FIG. 1B is a left side view. Is. Hereinafter, the outline of the cut-out weighing device 1 of FIG. 1 will be described.

With reference to FIG. 1, the cut-out weighing device 1 includes a hopper 2 (an example of the “hopper” described in the present claim) and a plurality of cutout pipes 3 (an example of the “cutout pipe” described in the present claim). , A plurality of motors 4-1 and a plurality of drive gears 4-2, a plurality of measuring buckets 5, a plurality of measuring instruments 7, a plurality of sub buckets 9, a chute 11, and a screw control unit 12 (claims of the present application). It is provided with an example of the “guidance member control unit” described in the above item). The measuring bucket 5 has a first open / close type damper 13. The sub-bucket 9 has a second openable damper 15. Further, the cutout pipe 3 has an annular gear 17 and a screw 19. The motor 4-1 and the drive gear 4-2 are examples of a cutout pipe control unit that controls the rotation speed, rotation direction, and rotation time of the cutout pipe 3.

The hopper 2 and the cutout pipe 3 are spatially communicated with each other at a communication portion (an example of the "communication portion" described in the claims of the present application). Further, the screw 19 penetrates the cutout pipe 3, and one end 6-1 is connected to the screw control unit 12 through the inside of the hopper 2. The screw control unit 12 controls the rotation speed, rotation direction, and rotation time of the screw 19.

The cut-out weighing device 1 cuts out the object to be weighed in fixed quantities. The cutout pipe 3 rotates to cut out the object to be weighed from the hopper 2. The drive gear 4-2 is fitted to the annular gear 17 and transmits the power of the motor 4-1 to the annular gear 17 to rotate the cutout pipe 3. Each cutout pipe 3 has one corresponding weighing bucket 5 and one sub-bucket 9 on the downstream side. Further, each of the individual measuring buckets 5 is connected to the corresponding measuring instrument 7. The weighing bucket 5 temporarily accommodates the weight to be weighed cut out from the corresponding cutout pipe 3. The measuring instrument 7 weighs the weight to be weighed contained in the corresponding weighing bucket 5. After the weighing is completed, the sub-bucket 9 accommodates the weighed object from the weighing bucket 5 and discharges the weighed object at the timing of the downstream process. For example, if the downstream process is a packaging machine, when the packaging bag is transported to the outlet of the chute 11, the plurality of second opening / closing dampers 15 open at different timings and toward the packaging machine via the chute 11. Discharge the objects to be weighed one by one. The chute 11 is located on the downstream side of the plurality of sub-buckets 9 as shown in (b), and the weigh-in material discharged from the sub-buckets 9 is led out to the downstream process.

Here, as shown in FIG. 1, the screw 19 does not have a length up to the discharge end 6-2 of the cutout pipe 3, and is inserted only halfway. Therefore, it is possible to individually control the intake from the hopper to the cutout pipe and the cutout from the cutout pipe. That is, the controllability is improved as compared with the configuration in which the screw is always extended to the discharge end by the pitch of the screw as in the old-fashioned cutting and weighing device.

Subsequently, with reference to FIG. 2, the mechanism for taking in the weight to be weighed in the cut-out weighing device of the present invention will be described. FIG. 2 is an enlarged view of the cut-out weighing device of FIG. 1 as viewed from above. The screw 19 has an axis 31 (an example of the "axis center" described in the present application) and a screw blade 33 around the axis 31 (an example of the "screw blade" described in the present application).

The weight to be loaded from the hopper 2, whether powder or leafy, is actively scraped into the cutout pipe by the rotation of the screw. Therefore, regardless of the shape and characteristics of the object to be weighed, it is easy to reliably take the object to be weighed into the cutout pipe and cut it out, which was difficult to take into the cutout pipe by the conventional passive uptake.

Further, the diameter of the screw blade 33 around the axis 31 is substantially equal to the inner diameter of the cutout pipe 3, although it is smaller than the inner diameter of the cutout pipe 3, and is a size that rotates at the inner surface thread of the cutout pipe 3. Therefore, the screw blade 33 scrapes off the deposits on the inner surface of the cutout pipe 3. As a result, the inner surface of the cutout pipe 3 is constantly refreshed. Therefore, the cleaning time of the cutout pipe 3 is reduced, and stable cutting is facilitated without stopping the cutting and weighing device 1.

Further, the cut-out weighing device 1 does not need to be provided with a separate mechanism for scraping off an object adhering to the inner surface of the cutout pipe 3 such as a scraper, which reduces the device cost.

Further, the shape of the screw will be described with reference to FIG. FIG. 3 is a diagram showing an example of a screw taken out from a cutout pipe. When mounted on the cut-out weighing device, the left side is the cutout pipe side and the right side is the hopper side. As shown in FIG. 3, the pitch of the screw blades is made to be constant. Also, the diameter of the screw blades is made larger inside the cutout pipe than in the hopper.

The rotation speed of the cutout pipe and the rotation speed of the screw may be linked and controlled. Specifically, increasing the rotation time or rotation speed of the screw for taking in increases the amount of taking in. Therefore, although it depends on what is to be weighed, it is generally preferable to control the rotation speed of the cutout pipe in order to keep the amount to be cut out constant with high accuracy. Since the rotation time of the cutout pipe is related to the weighing time, it is determined based on the weighing time. Further, when the rotation time or the rotation speed of the screw is reduced, it is preferable to perform the reverse control.

Further, the rotation direction of the cutout pipe and the rotation direction of the screw are individually controlled. It may be rotated in the same direction or in the opposite direction.

Further, as the shape of the screw, a plurality of screws having different blade sizes, lengths, and pitches may be used. The shape of the cutout pipe may also be different in the size of the inner diameter, the treatment of the inner surface, and the type of coating.
