Next, the operation of the material storage hopper 1 will be described.

When the material stored in the hopper 2 is discharged from the material discharge port 2a of the hopper 2 using the material storage hopper 1, first, a screw for reversely transferring the material provided in the hopper 2 is used. The distance G between the blade 4 and the material transfer screw blade 3 is adjusted to a predetermined distance.

Next, the material is stored in the hopper 2.

Next, the material transfer screw blade 3 is rotated at a predetermined rotation speed, and the material reverse transfer screw blade 4 is rotated at a predetermined rotation speed.

When the screw blade 4 for material reverse transfer is rotated in the direction shown by the arrow Ar3, the material stored in the hopper 2 is rotated by the rotation of the screw blade 4 for material reverse transfer, and the screw blade for material reverse transfer is rotated. 4, while being moved in the direction opposite to the material discharge port 2a (in the direction indicated by the arrow Ar4) while being agitated, the material drops by gravity toward the material transfer screw blade 3 provided below.

When the material transfer screw blade 3 is rotated in the direction of arrow Ar1, the material stored in the hopper is rotated by the rotation of the material transfer screw blade 3.
The material is moved in the direction of the material discharge port 2a (the direction shown by each of the arrows Ar2a and Ar2b) while being stirred by the material transfer screw blades 3b1 and 3b2.

Yes,
Large agglomerates (eg, agglomerates Ba1, Ba shown in FIG. 1)
2, Ba3... ) Are a plurality of small agglomerates (see, for example, small agglomerates Bb... Shown in FIG. 2).
To be.

The rotation of the screw blade 3 for transferring the material and the rotation of the screw blade 4 for transferring the material in the reverse direction cause a large agglomerate in the material (for example, the agglomerate Ba shown in FIG. 1).
1, Ba2, Ba3... ) Is loosened into a plurality of small agglomerates (see, for example, small agglomerates Bb... Shown in FIG. 2), and agitated and homogenized material is supplied to the screw blade 3 for material transfer. Due to the rotation, the material moves in the direction of the material discharge port 2a while being stirred.

That is, in the material storage hopper 1, the material stored in the hopper 2 is transferred to the tip of each screw blade part by the rotation of the material transfer screw blade 3 and the rotation of the material reverse transfer screw blade 4. Due to the force (shearing force) generated in the gap G between the large agglomerates (for example, the agglomerates Ba1, Ba2, Ba3 shown in FIG. 1) generated in the material
See ... ) Is converted to a plurality of small agglomerates (eg,
See small agglomerates Bb ... shown inside. ), While discharging the material from the material discharge port 2a of the hopper 2 while stirring so as to be homogeneous, so that it is difficult to discharge the material continuously and quantitatively with the conventional hopper. From the material discharge port 2a of the hopper 2, it is possible to continuously discharge quantitatively.

Further, in the material storage hopper 1, the rotation of the screw blade 3 for transferring the material and the rotation of the screw blade 4 for transferring the material in the reverse direction are rotated so as to be opposite to each other. Since the stored material is efficiently stirred, the material which is difficult to discharge continuously and quantitatively in the conventional hopper is made more homogeneous, and the material discharge port 2a of the hopper 2 is made. , Can be quantitatively continuously discharged.

Further, in the material storage hopper 1, since the distance G between the screw blade 3 for material transfer and the screw blade 4 for material reverse transfer can be adjusted, the screw blade 3 for material transfer and the material reverse screw blade 3 can be adjusted. The gap G between the transfer screw blade 4 and the large agglomerates (for example, the agglomerates Ba1, Ba2, Ba3,... Shown in FIG. 1) generated in the material is set according to the physical properties of the material stored in the hopper 2. .) Into a plurality of small agglomerates (eg, as shown in FIG. 2,
See small agglomerates Bb. ) Can be set to a distance that can be loosened.

As described above, the material transfer screw blade 3
In accordance with the physical properties of the material stored in the hopper 2, the distance between the material backward transport screw blades 4 and the agglomerates generated in the material (for example, the agglomerates Ba1, Ba2,
See Ba3 ... ) Is efficiently set to a distance that can be loosened into a plurality of small agglomerates (see, for example, small agglomerates Bb... Shown in FIG. 2). The material that is difficult to continuously discharge can be quantitatively continuously discharged from the material discharge port 2a of the hopper 2 in a more homogenized state.

Therefore, the material storage hopper 1 can be used not only when the material stored in the hopper is a normal powder material, but also when the material has a high water content.
Even a highly adhesive material can be quantitatively and continuously discharged from the material discharge port 2a of the hopper 2.

That is, the material stored in the hopper 2 is a culture medium, compost fertilizer, wood chip, or the like.
In the conventional hopper, even if it is considered that it is difficult to discharge the material from the material discharge port when stored in the hopper, such a material can be transferred to the hopper by using the material storage hopper 1. 2 can be discharged quantitatively and continuously from the material discharge port 2a.

Further, in the material storage hopper 1, the rotation speed of the material transfer screw blade 3 and the rotation speed of the material reverse transfer screw blade 4 are made variable.
The amount of material discharged from the material discharge port 2a of the hopper 2 can be set as a target discharge amount.

Further, in this example, in the region R1,
The rotation direction of the shaft 4a of the screw blade 4 for material reverse transfer and the rotation direction of the shaft 3a of the screw blade 3 for material transfer are rotated in mutually opposite directions (arrow A shown in FIG. 1).
See the directions indicated by r3 and arrow Ar1, respectively. Therefore, in the region R1, the cooperation between the screw blade 4 for material reverse transfer and the screw blade 3 for material transfer allows
The material in the region R1 is efficiently and without waste.
The material is discharged from the material discharge port 2a of the hopper 2.

In the region R4, the material in the region R4 is efficiently transferred to the region R3 by the material transfer screw blade 3.

As described above, in this example, by rotating each of the screw blades 3 for transferring the material and the screw blade 4 for transferring the material in the reverse direction, the material in the region R1 can be efficiently and without waste. 2 is discharged from the material discharge port 2a and the material in the region R4 is efficiently removed from the region R3.
Since the transfer is made to the side, the material stored in the hopper 2 can be discharged from the material discharge port 2a of the hopper 2 to the end without waste.

Next, the structure of the bag holding means 16 will be described.

FIG. 5 is a perspective view schematically showing the structure of the bag holding means 16. As shown in FIG.

The bag holding means 16 can hold the bag P by suction.

More specifically, the bag holding means 16
Includes a ring body 17 having a hollow, and suction means 18 connected to the ring body 17.

As the suction means 18, for example, a known
A vacuum pump, a blower, or the like is used. Further, the suction means 18 is configured to be driven when electric power is supplied from a commercial AC power supply. The member device indicated by 28 is provided with an inverter (frequency) provided to vary the frequency of the AC current supplied from the commercial AC power source for the purpose of saving power consumption and adjusting the suction force of the suction means 18. Conversion device).

The driving amount of the suction means 18 can be adjusted by a control unit (arithmetic processing unit) 22.

The ring body 17 is provided so as to surround the outer periphery of the material discharge port 15a of the destination hopper 15.

The ring body 17 has a plurality of suction holes 17a on its outer peripheral surface. In this example, the plurality of suction holes 17a are provided on the outer peripheral surface of the ring body 17 at equal intervals.

The ring body 17 has a connection port 17c for connecting the conduit 19.

Next, the operation of the material filling device 11 will be described.

FIG. 6 shows that the bag P
5 is a flowchart schematically illustrating an example of an operation program stored in advance in a storage unit of the control device 22 as an operation of filling a material into the storage device.

Using this material filling device 11, for example,
When bagging a culture medium for germinating and growing mushrooms and the like, first, a culture medium (material) obtained by fermenting and ripening a material mainly containing bagasse or rice straw is placed in a material storage hopper 1. Housed in hopper 2.

Next, the main switch (power switch) of the material filling device 11 is turned on (see step 1).

Then, an initial screen is displayed on the display means (not shown) of the control device (arithmetic processing device) 22 (see step 2).

In this initial screen, it is possible to select whether to operate the material filling apparatus 11 with manual setting or automatic (automatic) setting (see step 3).

When "manual" is selected in step 3, a manual input screen is displayed on the display means (not shown) of the control device (arithmetic processing device) 22 (step 4). reference).

In step 4, according to the display on the manual input screen, the rotation speed of the material transfer screw blade 3, the rotation speed of the material reverse transfer screw blade 4, the material transfer screw blade 3, and the material The distance G with the reverse transfer screw blade 4 is set, the target weight of the material to be filled in the bag P is set, and the conveying means 12 is set.
The transport speed can be set.

When the above setting is completed, the suction means 18 is driven by a predetermined drive amount.

Next, by attaching the opening of the bag P to the ring 17 of the bag holding means 16 and driving the suction means 18, the suction generated in each of the suction holes 17a. Using the airflow of the atmosphere, the ring body 17
The bag P is sucked and held.

At this time, the bag P is placed on the measuring means 21. If necessary, the weighing means mounting pedestal portion 24b is appropriately rotated with respect to the pedestal main body portion 24a, and the weighing means 21 is positioned at an optimal position for measuring the weight of the material to be filled in the bag P. Set to.

In this example, the ring body 17 is provided with a sensor (not shown) such as a pressure-sensitive sensor.
7, when the bag P is held, a sensor (not shown) is turned on, and information that this sensor (not shown) is turned on is transmitted to the control device (arithmetic processing device) 22. (See step 5).

In step 5, when the control device (arithmetic processing device) 22 receives the information that the sensor (not shown) is turned on, the start button (in this example,
The foot pedal 27 enters the operation mode. That is, when the start button (in this example, the foot pedal) 27 is turned on (pressed), the screw blade 3 for material transfer is turned on.
And the screw blade 4 for material reverse transfer start driving at the respective rotation speeds set in step 4 with the interval G set in step 4 therebetween, and the conveying means 12 Is driven at the set transport speed.

On the other hand, the control device (arithmetic processing device) 22
If the information that the sensor (not shown) is turned on is not received, the start button (in this example, the foot pedal) 27 is not in the operation mode. Even if the button (the foot pedal in this example) 27 is turned on (push operation), each of the screw blade 3 for material transfer, the screw blade 4 for reverse material transfer, and the conveying means 12 is not driven.

In step 6, when the start button (in this example, the foot pedal) 27 is turned on (push operation), if the bag P is held in the ring body 17, the screw blade 3 for transferring the material is turned on. Each of the screw blade 4 for material reverse transfer and the transport means 12 is driven at a predetermined speed, and the material (in this example, the culture stored in the hopper 2 in the hopper 2) is loaded into the bag P held by the ring body 17. The filling operation of the medium is started (see step 7).

When the measuring means 21 detects in step 4 that the weight of the material to be filled into the bag P (in this example, the culture medium contained in the hopper 2) has reached the target weight, this signal is output. Is sent from the weighing means 21 to the control device (arithmetic processing device) 22.

The controller (arithmetic processing unit) 22 reads the weight of the material (the culture medium contained in the hopper 2 in this example) from the measuring means 21 into the bag P. When a signal is detected indicating that the weight of the material (the culture medium contained in the hopper 2 in this example) has reached the target weight, the screw blade 3 for material transfer, the screw blade 4 for material reverse transfer, and the conveying means 12 Stop each (see steps 8 and 9).

In this example, the control device (arithmetic processing device) 22 determines that the weight of the material (the culture medium contained in the hopper 2 in this example) to be filled into the bag P is measured by the measuring means 21. Upon receiving a signal indicating that the weight of the material to be filled into the bag P (in this example, the culture medium contained in the hopper 2) has reached the target weight, the drive amount of the suction means is reduced, and the operator The bag P is easily removed from the ring body 17.

Next, in step 10, the operator
When the bag P is removed from the ring body 17, a sensor (not shown) provided on the ring body 17 is turned off, and a signal indicating that the sensor (not shown) is turned off is given.
It is sent to the control device (arithmetic processing device) 22. When the control device (arithmetic processing device) 22 receives a signal indicating that this sensor (not shown) has been turned off from a sensor (not shown) provided on the ring body 17, the next bag P (In this example, a culture medium contained in the hopper 2) (see step 10).

When the main switch (not shown) is turned off after step 10, the bag P is filled with the material (in this example, the culture medium contained in the hopper 2). The work is completed (see step 11).

In step 3, "manual"
Is selected, during the operation of filling the bag P with the material (the culture medium contained in the hopper 2 in this example), if necessary, the rotation speed of the material transfer screw blade 3 is appropriately set, The setting of the rotation speed of the screw blade 4 for material reverse transfer, the setting of the distance G between the screw blade 3 for material transfer and the screw blade 4 for material reverse transfer, the setting of the target weight of the material to be filled in the bag P, and the conveyance Each of the transport speeds of the means 12 can be changed.

On the other hand, if "auto" is selected in step 3, an input screen for auto is displayed on the display means (not shown) of the control device (arithmetic processing device) 22 (step 3). 12).

In step 12, the rotation speed of the screw blade 3 for material transfer, the rotation speed of the screw blade 4 for reverse material transfer, the screw blade 3 for material transfer, It is possible to set the distance G with the reverse transfer screw blade 4, set the target weight of the material to be filled in the bag P, and set the transfer speed of the transfer means 12. The above condition setting items are the same as those in the case of the manual input screen. However, in the automatic input screen, the weight before the target weight of the material to be filled in the bag P (weight less than the target weight) can be set. (Refer to “Setting of filling speed change weight” in FIG. 6).

The weight (weight less than or equal to the target weight) before the target weight of the material to be filled in the bag P is determined by the rotation speed of the material transfer screw blade 3 and the material reverse transfer screw blade 4.
Since the rotation speed and the transfer speed of the transfer means 12 are the target weights when the speed is lower than the initial set speed, in this specification, the target weight of the material to be filled in the bag P, which can be set in this step 12, is set. The front weight (weight equal to or less than the target weight) is referred to as “filling speed change weight” for convenience.

Further, on the auto input screen, the rotation speed of the material transfer screw blade 3 and the material reverse transfer screw blade 4 after the weight of the material to be filled in the bag P becomes equal to or greater than the change speed of the filling speed. Rotation speed of the conveying means 12
Can be set (see "Setting of speed after change to initial speed").

In this example, the case where the setting of the charging speed change weight and the setting of the speed after the change to the initial speed can be appropriately performed by the operator has been described. When you set the weight, for example,
"Filling speed change weight" = "Target weight" x "α%" (α%
=, For example, 80%) may be automatically set to a predetermined weight.

Further, the rotation speed of the screw blade 3 for transferring the material after the weight of the material to be filled in the bag P becomes equal to or more than the change weight of the filling speed sets the initial rotation speed of the screw blade 3 for transferring the material. Then, for example, “the rotation speed of the material transfer screw blade 3 after the filling speed change weight or more” = “the initial rotation speed of the material transfer screw blade 3” × “β%” (β% = for example, 80%), a predetermined rotation speed may be automatically set.

Further, after the weight of the material to be filled in the bag P becomes equal to or greater than the filling speed change weight, the rotation speed of the screw blade 4 for reverse material transfer is changed to the rotational speed of the screw blade 4 for reverse material transfer.
When the initial rotation speed of the screw blade 4 is set to, for example, “the screw blade 4 for material reverse transfer after the filling
Rotation speed "=" initial rotation speed of material reverse transfer screw blade 4 "x" γ% "(γ% = 80%, for example) so as to be automatically set to a predetermined rotation speed. It may be.

Further, the transfer speed of the transfer means 12 after the weight of the material to be filled in the bag P becomes equal to or more than the change rate of the filling speed is set by setting the initial transfer speed of the transfer means 12, for example, Conveying means 1 after exceeding the speed change weight
2 ”=“ Initial transfer speed of the transfer unit 12 ”×
A predetermined transport speed may be automatically set, such as “δ%” (δ% = for example, 80%).

In the above examples, the same values are shown as α%, β%, γ%, and δ%.
Needless to say, each of β%, γ%, and δ% may be a different value.

When the above setting is completed, the suction means 18 is driven by a predetermined drive amount.

Next, the opening of the bag P is attached to the ring body 17 of the bag holding means 16 and the suction means 18 is driven, so that the suction holes 17a. Using the airflow of the atmosphere, the ring body 17
The bag P is sucked and held.

At this time, the bag P is placed on the measuring means 21. If necessary, the weighing means mounting pedestal portion 24b is appropriately rotated with respect to the pedestal main body portion 24a, and the weighing means 21 is positioned at an optimal position for measuring the weight of the material to be filled in the bag P. Set to.

In this example, the ring body 17 is provided with a sensor (not shown) such as a pressure-sensitive sensor.
7, when the bag P is held, a sensor (not shown) is turned on, and information that this sensor (not shown) is turned on is transmitted to the control device (arithmetic processing device) 22. (See step 13).

In step 13, when the control device (arithmetic processing device) 22 receives the information that the sensor (not shown) is turned on, the start button (in this example, the foot pedal) 27 is set to the operation mode. become. That is,
The start button (in this example, the foot pedal) 27 is
When turned on (push operation), the screw blade 3 for material transfer and the screw blade 4 for material reverse transfer are moved to Step 1
Driving is started at the respective rotation speeds set in Step 4 at an interval G set in Step 2, and the transfer means 12 is driven at the transfer speed set in Step 4.

On the other hand, the control device (arithmetic processing device) 22
If the information that the sensor (not shown) is turned on is not received, the start button (in this example, the foot pedal) 27 is not in the operation mode. Even if the button (the foot pedal in this example) 27 is turned on (push operation), each of the screw blade 3 for material transfer, the screw blade 4 for reverse material transfer, and the conveying means 12 is not driven.

In step 14, when the start button (foot pedal in this example) 27 is turned on (pressed), if the bag P is held by the ring body 17, the screw blade 3 for transferring the material is turned on. Each of the material reverse transfer screw blades 4 and the conveying means 12 is driven at a predetermined initial set speed, and the material (in this example, into the hopper 2 in the bag P held by the ring body 17). The filling operation of the accommodated culture medium) is started (see step 15).

In step 16, the measuring means 21 determines
When it is detected that the weight of the material to be filled into the bag P (in this example, the culture medium contained in the hopper 2) has reached the weight at which the filling speed has been changed, this signal is sent from the measuring means 21 to the control device (calculation processing). Device 22).

The controller (arithmetic processing unit) 22 reads the weight of the material (the culture medium contained in the hopper 2 in this example) from the measuring means 21 into the bag P. When receiving a signal indicating that the weight of the material (in this example, the culture medium accommodated in the hopper 2) has reached the filling change speed weight, the rotation speed of the material transfer screw blade 3 is increased to the filling speed change weight or more. The rotation speed of the screw blade 3 for material transfer after the rotation becomes equal to the rotation speed of the screw blade 4 for material reverse transfer after the rotation speed of the screw blade 4 for material reverse transfer becomes equal to or more than the filling speed change weight, and the transfer is performed. The conveying speed of the means 12 is set to the conveying speed after the filling speed change weight or more, and the filling operation into the bag P is performed by the weighing unit 21 by the material (the hopper in this example) filled in the bag P. Housed in 2 Weight of the culture medium) is performed until the target weight (see step 17 and step 18).

In step 18, the measuring means 21
When it is detected that the weight of the material (the culture medium contained in the hopper 2 in this example) to be filled in the bag P has reached the target weight, this signal is sent from the measuring means 21 to the control device (arithmetic processing device). 22.

The control device (arithmetic processing device) 22 reads the weight of the material (the culture medium contained in the hopper 2 in this example) from the weighing means 21 into the bag P. When a signal is detected indicating that the weight of the material (the culture medium contained in the hopper 2 in this example) has reached the target weight, the screw blade 3 for material transfer, the screw blade 4 for material reverse transfer, and the conveying means 12 Stop each (see step 19).

In this example, the control device (arithmetic processing device) 22 determines from the measuring means 21 that the weight of the material (the culture medium contained in the hopper 2 in this example) to be filled into the bag P is Upon receiving a signal indicating that the weight of the material to be filled into the bag P (in this example, the culture medium contained in the hopper 2) has reached the target weight, the drive amount of the suction means is reduced, and the operator The bag P is easily removed from the ring body 17.

Next, in step 20, the operator
When the bag P is removed from the ring body 17, a sensor (not shown) provided on the ring body 17 is turned off, and a signal indicating that the sensor (not shown) is turned off is given.
It is sent to the control device (arithmetic processing device) 22. When the control device (arithmetic processing device) 22 receives a signal indicating that this sensor (not shown) has been turned off from a sensor (not shown) provided on the ring body 17, the next bag P (In this example, a culture medium contained in the hopper 2) (see step 20).

When the main switch (not shown) is turned off after step 20, the bag P is filled with the material (the culture medium contained in the hopper 2 in this example). The operation is completed (see step 21).

In the material filling device 11, since the material storage hopper 1 is used, the material (in this example, the culture medium) stored in the hopper 2 is transferred to the material transfer device by rotating the material transfer screw blades 3 and rotating the material. Since the appropriate agglomeration is formed by the rotation of the reverse transfer screw blade 4, the material can be quantitatively and continuously discharged from the material discharge port 2a of the hopper 2.

The material (the culture medium in this example) discharged from the material discharge port 2a of the hopper 2 is transported by the transport means 12 and filled in the bag P held by the bag holding means 16.

Since the weight of the material to be filled in the bag P can be measured by the measuring means 21, the weight of the material (the culture medium in this example) to be filled in the bag P is equal to the target weight. , The bag P can be filled with a predetermined amount of material by ending the filling operation.

That is, in the material filling apparatus 11, the operation of filling the bag P with the material (in this example, the culture medium) can be automatically performed by a machine without human intervention.

As a result, not only can the labor of filling the bag P with the material (in this example, the culture medium) be saved, but also the operation of filling the bag P with the material (in this example, the culture medium) can be performed. At this time, it is possible to prevent the material filled in the bag P from being contaminated with various bacteria.

Further, in the material filling device 11, since the rotation speed of the screw blade 3 for transferring the material, the rotation speed of the screw blade 4 for transferring the material in the reverse direction, and the transfer speed of the transfer means 12 can be adjusted, The material can be filled into the container at an optimum speed.

Further, in the material filling apparatus 11, the distance G between the screw blade 4 for reverse transfer of the material-filled material and the screw blade 3 for material transfer is adjusted to a predetermined distance, so that the material is stored in the hopper 2. Large agglomerates occurring in the material (for example, agglomerates Ba1, Ba shown in FIG. 1)
2, Ba3 .... ) To a plurality of agglomerates of a predetermined size (for example, see agglomerates Bb... Shown in FIG. 2).
By loosening the material, the material can be quantitatively and continuously discharged from the material discharge port 2a of the hopper 2.

Further, in the apparatus 11, the work of filling the bag P with the material is performed quickly until the target weight of the material to be filled in the bag P reaches a predetermined weight (the changing speed of the filling speed). Therefore, the bagging operation of the material (in this example, the culture medium) can be performed in a short time.

Further, in the material filling apparatus 11, the weighing means 21 detects that the target weight of the material (the culture medium in this example) to be filled in the bag P has reached a predetermined weight (filling speed change weight). Then, each of the screw blade 3 for material transfer, the screw blade 4 for material reverse transfer, and the conveying means 12 is automatically driven at a speed lower than a predetermined speed. Can be filled so that the filling amount of the material into the target weight accurately matches the target weight.

In the material filling apparatus 11, the bag P is held by the bag holding means 16 by suction.
6 can hold the bag P, and the bag can be removed from the bag holding means 16 simply by weakening or stopping the suction.

More specifically, in the material filling device 11, when the suction means 18 is driven, a plurality of suction holes 17a provided on the outer peripheral surface of the ring body 17 are provided.
Since an airflow of a suction atmosphere is generated in each of the cases, the bag P can be easily attached to the ring 17 of the bag holding means 16 simply by locating the opening of the bag P on the ring 17. . Further, if the driving amount of the suction means 18 is reduced or stopped, the bag P can be easily removed from the ring body 17.

In this way, the bag changing operation can be performed very easily when the bag P is filled with the material.

Further, in the material filling device 11, the entire material filling device 11 can be moved by the moving means, so that the bagging operation of the material can be performed at a place convenient for the operation.

More specifically, in the material filling device 11, the material storage hopper 1, the transporting means 12, the transport destination hopper 15, and the bag holding means are mounted on a pedestal 24 of a truck having wheels 25a, 25b, 25c and 25d. 16, the weighing means 21 and the control means (arithmetic processing unit) 22 are provided, so that the wheels 25a, 25b, 25c and 25d can be easily moved to a target place.

Further, in the material filling device 11, the weighing means 21 is provided on the weighing means mounting pedestal portion 24b rotatably provided on the pedestal main body portion 24a. The pedestal portion 24b for attaching the measuring means is changed to the pedestal main portion 24a in accordance with the size of the bag P held in
By rotating, the measuring means 21 can be provided at an optimal position for measuring the material (the culture medium in this example) filled in the bag P.

Further, in the material filling apparatus 11, a jig 26 for hanging a forklift is attached to the moving means (the carriage 23).
By attaching the fork of the forklift to the jig 26 for hanging the forklift, the material filling device 11 can be routed by the forklift.

Next, the material filling apparatus 11 according to the present invention will be described below in accordance with preferred products.

The hopper 2 of the material storage hopper 1 includes:
One having a volume of 5 m ³ was used.

Thus, for example, in the case of a bag P for 15 kg, if the hopper 2 is filled with a material (in this example, a culture medium) until it is full, about 40 bags can be filled. Needless to say, the hopper 2 can be arbitrarily charged and replenished with a material (in this example, a culture medium) even during the bagging operation, so that the hopper 2 can be continuously filled.

The filling speed of each of the bags P depends on the setting of the rotation speed of the screw blade 3 for material transfer, the setting of the rotation speed of the screw blade 4 for reverse transfer of the material, and the setting of the transfer speed of the transfer means 12. If set alone or in combination of at least two of them, it can be changed arbitrarily, but in this device 11, the amount of bagging work / time is
When a bag of 15 kg is used as the bag P, the maximum bagging work / time is set to 180 bags / hour.

The weighing error of the bagged material relative to the target weight is 0.5 kg of soil even in the case of a coarse fibrous and highly cohesive culture medium as in the case of the present material. Note that, depending on the type and quality of the material, the weighing error with respect to the target weight of the bagged material can reach 0.1 kg of soil.

The method for filling the bag P with the material (the culture medium in this example) is as follows.
First, an empty bag P is set in the bag holding means 16. Then, if an empty bag P is set in the bag holding means 16, a sensor (not shown) detects that the bag P has been set in the bag holding means 16, and the apparatus 11 enters a startable state. .

Accordingly, the operator only needs to turn on (step on) the start button (foot pedal in this example) 27 in this state. Then, the entire apparatus 11 is activated, and the filling operation of the material (the culture medium in this example) into the bag P held by the bag holding means 16 is started. If the filling speed change weight is set to, for example, 80% of the target weight, the bag P held by the bag holding means 16
When the filling amount of the material (the culture medium in this example) reaches 80% of the target weight, the screw blade 3 for transferring the material is used.
, The rotation speed of the material reverse transfer screw blade 4 and the conveyance speed of the conveyance means 12 are automatically decreased by one step, and the accuracy of measuring the amount of the material (in this example, the culture medium) filled in the bag P is measured. And continue bagging until the target weight is reached.

Materials in bag P (in this example, culture medium)
When the filling amount of the material reaches the target weight (set value), the screw blade 3 for material transfer, the screw blade 4 for material reverse transfer, and the conveying means 12 are all stopped, and the first bag packing operation (filling operation) ) Is completed.

When the first bag filling operation (filling operation) is completed, the completed bag P is removed from the bag holding means 16.

Thereafter, when the next empty bag P is set in the bag holding means 16, the same operation as described above is repeated, and the next empty bag P is filled with the material (in this example, the culture medium). ) Is automatically performed.

In the apparatus 11, the suction means (in this example, a vacuum pump is used) of the bag holding means 16 is used.
8, the continuous operation is performed, but when the filling amount of the material (the culture medium in this example) into the bag P reaches the target weight (set value), the driving amount (rotation speed) automatically decreases, The suction force of the suction means (in this example, a vacuum pump is used) is automatically weakened, so that the worker can remove a predetermined amount of material (this In the example, the bag P filled with the culture medium) can be easily removed.

The device 11 has a capacity of 10 kg to 15 kg.
Although the bag P for g is targeted, the work of filling the material into a bag having a capacity of several hundred kg such as a transbag can also be performed.

That is, when the bag P is a bag having a capacity of several hundred kg, such as a transbag, the weighing means mounting pedestal portion 24b is arranged with respect to the pedestal main body portion 24a around the rotating shaft 24c. By rotating the bag P by a predetermined amount, the bag P
1.

In the above description, the operation of the present apparatus 11 has been described in the case where the automatic operation is selected and the automatic operation according to the program is performed. Material filling operations can also be performed.

Further, since the present apparatus 11 is provided with a jig 26 for suspending the lift, the present apparatus 11 can be moved to an arbitrary place by a forklift truck.
