Abstract

PURPOSE:To provide the vibrating frame body for packing a developer which can rapidly and efficiently pack the developer at a high density. CONSTITUTION:The vibrating frame body A for packing the developer used for primarily packing the developer into a developer supplying container, then applying vibrations to the developer supplying container to lower the powder level of the developer, thereby secondarily packing the developer is constituted of a light metal alone. Since the vibrating frame body A for packing the developer is constituted of the light metal alone, the vibrations applied to the developer supplying container via the vibrating frame body A are hardly attenuated, and the self-excited vibration of the container is moreover added. The developer is thus packed rapidly and efficiently into the container with high density. Since the vibrations are effectively transmitted to the developer supplying container, the vibration time with the conventional container is drastically shortened and the cost of packing the developer is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a developer filling vibrating frame for filling a developer, a carrier pallet, a funnel, a developer filling method and apparatus.

[0002]

2. Description of the Related Art Conventionally, a developer has been used in a copying machine, a printer or the like using an electrostatic photography method. Generally, a developer having a particle diameter of about several microns is used, and there are various color developers including black.

These developers are replenished by discharging the developers from a developer supply container to a developer receiving container installed in the main body of a copying machine or the like.

By the way, as a method of filling the developer supply container with the developer, a method of directly filling the developer from the hopper into the developer supply container is generally used. At this time, if the amount of the developer filled becomes high density with respect to the volume of the developer supply container, after the primary filling, the developer is temporarily stored while being vibrated for a certain period and then filled once or twice again. The multiple filling method is adopted.

In particular, recently, the global environmental problem concerning waste has been greatly highlighted, and it is necessary to increase the filling amount of the developer to be filled in the developer supply container as much as possible and reduce the amount of the developer supply container to be discarded. The manufacturing side is also making efforts.

Further, by increasing the filling amount and performing high-density filling, the number of times of replenishing the developer supply container is reduced, and the copy cost per sheet is reduced.

Due to the environmental problems and the cost reduction as described above, there is a demand for high density packing of the developer.

By the way, the above-mentioned vibration for a certain period is 1
This is an operation for lowering the powder surface of the developer in the developer supply container after the second filling so that more developer can be filled when the developer is secondarily filled or thirdly filled.

Thus, a pallet is used to hold the developer supply container while applying the vibration for a certain period to the developer supply container.

The structure of a typical pallet is composed of a bottom plate and a lateral holding block. In the structure of the bottom plate, a metal is used for the bottom part that directly contacts the vibrating part, and a resin material such as polyacetal resin or Teflon resin that is not easily scratched on the developer supply container is used for the upper part that contacts the developer supply container. It is used. The lateral pressing block is made of the same resin material.

By the way, as the bottom plate and the lateral pressing block, those for surely fixing the developer supply container without backlash by binding with screws or the like, or the metal portion of the bottom plate and the upper part of the bottom plate and the lateral pressing block are made of the same resin. The one that is integrally molded with the one that is firmly adhered with an adhesive or the like is used.

[0012]

However, in the conventional pallet, the resin material of the upper portion of the bottom plate and the lateral pressing block makes it difficult to transmit the vibration to the developer supply container, and the vibration is considerably damped by the direct vibration. To the developer supply container. For this reason, the powder surface drop due to the vibration of the developer in the developer supply container is less than initially assumed, and a predetermined amount of the developer cannot be filled in the secondary filling or the tertiary filling.

Further, in order to reduce the cost related to filling as much as possible, it is necessary to shorten the time for applying vibration, but the time required for lowering the predetermined powder surface of the developer for the purpose of damping the vibration is extended, and therefore, the filling is performed. The whole time becomes long and the filling cost increases.

Further, since the number of developer supply containers temporarily stored while being vibrated is limited by the area of the bottom plate of the pallet larger than the sectional area of the developer supply container, a large number of developer supply containers are vibrated at one time. In such a case, the number of containers that can be vibrated at one time is reduced, and the filling time is rate-determined and the filling cost is increased.

Therefore, an object of the first, second and third inventions is to provide a vibrating frame for filling a developer, which can efficiently perform high density filling of the developer in a short time. is there.

The object of the fourth and fifth inventions is as follows.
It is an object of the present invention to provide a developer-filling transport pallet capable of efficiently filling a developer with high density in a short time.

By the way, as a method of filling the developer supply container with the developer, a method of directly filling the manufactured developer into the developer supply container from a hopper is generally used. In this case, the developer discharged from the hopper is discharged from the discharge nozzle by the auger screw filling method, for example.

In recent years, the body of a copying machine or the like is often designed to be as compact as possible from the viewpoint of space saving. For this reason, the developer supply container itself has become very compact, and the diameter of its filling port has become smaller.

There is a case where the developer is directly filled into the developer supply container from the discharge port through the small-diameter filling port. However, depending on the nature of the developer, for example, in the auger screw type filling method, an auger screw and an auger casing are used. Since there is a possibility that a phenomenon such as fusion of the developer or coarsening of the developer may occur during the interval, the diameter of the discharge nozzle is made larger than the diameter of the filling port, and the developer discharged from the discharge nozzle is filled with the developer filling funnel. In many cases, a method of guiding the developer to the filling port of the developer supply container is also used.

By the way, the conventionally used developer filling funnel is made of a metal such as stainless steel having abrasion resistance and rust prevention, and has a conical developer discharge receiving portion and a developer supplying portion. And a developer pouring portion having a diameter slightly smaller than the filling port of the container. The developer pouring portion is attached in parallel with the funnel center line from the narrowed central portion of the conical developer discharge receiving portion.

However, when the developer is filled using the filling funnel, a large amount of the developer is temporarily accumulated in the developer discharge receiving portion of the funnel during the filling, resulting in development. The developer is often clogged with the agent filling funnel. It is considered that this is because the fluidity of the developer does not follow the discharge speed from the developer hopper, and the developer is blocked in the funnel due to frictional resistance with the surface of the funnel.

In order to prevent the above funnel clogging when the conventional developer filling funnel is used to fill the developer, the developer discharging speed from the developer hopper should be set to such an extent that the developer is not blocked by the funnel. I have to lower it,
According to this, the filling speed is significantly reduced, and the filling cost is significantly increased.

Therefore, an object of the sixth and seventh inventions is to provide a developer filling funnel capable of increasing the discharging speed of the developer from the developer hopper and reducing the filling cost.

By the way, in the case of high-density filling of the developer, the primary filling is performed to the fullest extent, and then the powder surface of the developer in the container after the primary filling is lowered as much as possible. It is necessary to secure a volume corresponding to the filling after the next filling,
Therefore, the time for vibrating the container becomes long and the production tact decreases, or the condition of the vibration becomes too strong and the developer filled from the developer filling port of the container scatters to control the filling amount. Not only becomes impossible, but also the filling line may be soiled.

Therefore, an object of the ninth invention is to provide a developer filling method capable of efficiently filling a high density of the developer in a short time.

Another object of the tenth aspect of the invention is to provide a developer filling device capable of efficiently filling the developer with high density in a short time.

[0027]

[0036]

According to the first aspect of the invention, not only the vibration applied to the developer supply container is hardly damped, but also self-excited vibration of the container is added. Therefore, the secondary filling or the tertiary filling of the developer is performed. It becomes possible to secure a predetermined amount. This makes it possible to fill the developer with higher density, reduce the number of developer supply containers used, and further reduce waste.

【Example】

[First Invention] An embodiment of the first invention will be described below with reference to the accompanying drawings.

<First Embodiment> FIG. 1 is a perspective view of a developer-filling vibrating frame A according to the present invention. As shown, the vibrating frame A has a vertical frame 10, a horizontal frame 11, and It is configured by combining the bottom plate 13. In addition, the capacity of the vibration device is small,
When the withstand load is small, the bottom plate 13 is omitted and the vertical frame 10
The vibrating frame body A may be configured only by the horizontal frame 11.

In the vibrating frame A, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X shown in FIG. The shape and dimensions of the developer supply container X are set according to the developer supply container X so that the developer supply container X does not rattle.

By the way, as a method of constructing each of the frames 15, that is, a method of combining the vertical frame 10 and the horizontal frame 11, binding by screws or the like, or forming on the vertical frame 10 and the horizontal frame 11 respectively as shown in FIG. There are combinations of recesses 18
In any method, it is necessary to surely combine the vertical frame 10 and the horizontal frame 11 so that each frame 15 does not rattle due to vibration.

Thus, the vertical frame 10, the horizontal frame 11, and the bottom plate 1
The developer-filling vibrating frame A composed of 3 is composed of a light metal that is as light and thin as possible so that the vibration from below is transmitted to the developer supply container X as it is, with as little vibration as possible. It As the light metal, aluminum is desirable in terms of durability and cost.

If the vertical frame 10, the horizontal frame 11, and the bottom plate 13 are made of aluminum, the thickness thereof is about 1 mm to 5 m.
m is preferable, and 1 mm to 3 mm is more preferable.

The developer-filling vibrating frame A is securely mounted and mounted on the vibrating plate 100, as shown in FIG. When mounting the vibrating frame body A, the vibrating frame body A and the vibrating plate 100 are prevented from rattling.
The bottom plate 13 is completely attached to the diaphragm 100 with double-sided adhesive tape or the like, or is completely fixed with screws or the like.

Next, a high-density filling method of the developer t using the vibrating frame A for filling the developer according to the present invention will be described.

As shown in FIG. 5, the discharge nozzle 50 of the hopper 20 in which the freshly manufactured developer t is stored.
An auger 51 that discharges the developer t while regulating the discharging speed is provided inside.

The developer t in the hopper 20 is discharged from the discharge nozzle 50 at a constant discharge speed. The developer t discharged from the discharge nozzle 50 then moves to the funnel 70 having a diameter that matches the diameter of the filling port 2 of the developer supply container X, and finally passes through the filling port 2 from the funnel 70 to develop. The developer is discharged toward the developer supply container X, and the developer supply container X is discharged.
It is primarily filled inside.

As described above, after the primary filling of the developer t is completed, as shown in FIG. 3, the developer supply containers X whose primary filling is completed are sequentially filled with the developer on the vibrating plate 100. Each frame 15 of the vibrating frame body A is loaded one after another.

A vibrating device is attached to the lower portion of the vibrating plate 100. As a method of driving the vibration device, there are an air cylinder type vibration method and an electromagnetic type vibration method. The air cylinder type vibration method vibrates the entire diaphragm 100 by regulating the air pressure, but since it is an air type, the frequency and the amplitude simultaneously increase and decrease. On the other hand, in the electromagnetic vibration method, both the frequency and the amplitude can be controlled by using the voltage regulation and the converter together.

Therefore, the electromagnetic vibration method can control the vibration more precisely, and the developer supply container X for the developer t can be controlled.
It is possible to regulate the decrease of the powder surface inside. For example, in FIG.
The electromagnetic vibrating device Y as shown in FIG. 2 is used. The electromagnetic vibrating device Y includes a vibration source main body 150, a power switch 80, a frequency conversion knob 60 and an amplitude adjustment knob 90 provided in the outer frame 160. It is configured to include. A vibration gap 110 is formed in the outer frame 160.

Thus, in the above electromagnetic vibrating device Y,
When the power switch 80 is turned on, the alternating current of the frequency adjusted by the built-in converter is applied to the electromagnetic vibration device Y.
The optimum vibration can be obtained by adjusting the amplitude of the flow.

Next, the reduction of the powder surface of the developer t in the developer supply container X will be described.

As shown in FIG. 6, by the primary filling, the developer t is filled to the position where the powder surface in the developer supply container X is a.

After that, when the developer supplying container X on the vibrating plate 100 is filled with the developer supply container X and is vibrated, the vibration is generated via the developer filling vibrating frame A. It is transmitted to the supply container X. Due to the vibration of the developer supply container X, the developer t located at the position a immediately after the filling is filled with the developer t.
The powder surface of is lowered to the position of b. The larger the distance L between the powder surface a and the powder surface b, the larger the filling amount of the developer t that can be filled by the secondary filling.

In order to fill the developer supply container X with the developer t in the highest possible density in a short time, it is necessary to make an effort to increase the primary filling amount and the secondary filling amount of the developer t as much as possible. . In particular, the amount of the developer t to be primarily filled may be an amount with which the developer t is filled up to just before the filling port 2 of the developer supply container X, and this amount is regulated by the rotation speed of the auger 51.

By the way, in transmitting almost 100% of the vibration to the developer supply container X, the vibration transmitting performance of the developer filling vibrating frame A according to the present invention is an important factor.

The vibrating frame A for filling the developer according to the present invention is
As described above, in addition to being as light and thin as possible, it is possible to transmit vibrations to the developer supply container X while suppressing the vibration to a minimum, and as a result of the self-excited vibration of the developer supply container X, A vibration that is further amplified than the transmitted vibration is applied to X, and it is possible to maximize the distance L for lowering the powder surface in the developer supply container X within a fixed time.

Therefore, the developer t is 2 by the amount of the decrease L of the powder surface.
The next filling amount can be increased, which enables the high density filling of the developer t.

The vibrating frame A for filling the developer according to the present invention
Is used, it is possible to increase the number of developer supply containers X that can be mounted on the vibration plate 100 having a limited area at one time and vibrated, and increase the tact of filling the developer t to reduce the filling cost. It becomes possible.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

As shown in FIG. 7, as in the first embodiment,
The developer filling vibrating frame B according to this embodiment is configured by combining a vertical frame 10, a horizontal frame 11, and a bottom plate 13.
As in the first embodiment, when the vibration device has a small capacity and a small withstand load, the bottom plate 13 may be omitted and the vertical frame 10 and the horizontal frame 11 may constitute the vibration frame body B. .

In the vibrating frame B, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X shown in FIG. 8 is to be inserted. The shape and the size of the developer supply container X are set according to the developer supply container X so that the developer supply container X does not rattle.

Then, the vertical frame 10 and the horizontal frame 1 of the vibrating frame B
As shown in FIG. 7, a lightening portion 19 is formed on the No. 1 except for the mutually combined portions. This lightening part 19
As a result, the weight of the developer-filling vibrating frame B is significantly reduced, and vibration damping can be minimized.

Further, the developer-filling vibrating frame B composed of the vertical frame 10, the horizontal frame 11 and the bottom plate 13 is made of a light metal such as aluminum which is as light and thin as possible like the first embodiment. It

Next, as shown in FIG. 8, the developer-filling vibrating frame B is securely mounted and mounted on the vibrating plate 100.

As a result, the same high density filling of the developer as in the first embodiment is performed using the developer filling vibration frame B mounted on the vibration plate 100. It was possible to fill the developer with a density higher than that of the equivalent, and it was possible to reduce the filling cost by maximally increasing the number of containers X that can be vibrated at one time.

The developer-filling vibrating frame B according to the present embodiment is greatly reduced by the lightening portion 19 as compared with the developer-filling vibrating frame A used in the first embodiment. It was achieved, and it became possible to minimize vibration damping more effectively.

This embodiment is especially useful when the vibration device has a small withstand load, a large number of developer supply containers are vibrated at one time, or a large developer filling amount per container. Is effective for.

<Third Embodiment> Next, a third embodiment of the present invention will be described.

Similar to the first embodiment, the developer filling vibrating frame C according to the present embodiment has a vertical frame 10, a horizontal frame 11 and a bottom plate 1.
It is configured by combining three. As in the first embodiment, when the vibration device has a small capacity and a small load resistance, the bottom plate 13 may be omitted and the vertical frame 10 and the horizontal frame 11 may constitute the vibration frame body C. .

In the vibrating frame C, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X shown in FIG. The shape and the size of the developer supply container X are set according to the developer supply container X so that the developer supply container X does not rattle.

By the way, in this embodiment, as shown in FIG. 8, a developer supply container X is provided in each of the vertical frames 10 and the horizontal frames 11.
A corner remover 30 is formed to facilitate the loading into the vehicle 5.

By the above-mentioned corner removal 30,
An operator or a robot system does not take time to load the developer supply container X, and the surface of the container X is not easily scratched when the developer supply container X is taken out.

As in the first embodiment, the developer-filling vibrating frame C composed of the vertical frame 10, the horizontal frame 11 and the bottom plate 13 is made of a light metal such as aluminum which is as light and thin as possible.

The developer filling vibrating frame C is securely mounted on the vibrating plate 100 as in the first embodiment (see FIG. 3).

Then, the same high-density developer was filled as in the first embodiment by using the developer-filling vibrating frame C mounted on the vibrating plate 100, which was the same as in the first embodiment. As described above, the high-density developer can be filled, and the number of containers X that can be vibrated at one time can be maximized to reduce the filling cost.

The use of the developer-filling vibrating frame C according to the present embodiment results in a corner removal 30 as compared with the case of using the developer-filling vibrating frame A according to the first embodiment. In addition, it is very effective because it does not take time to load the developer supply container X, and when the developer supply container X is taken out, the surface of the container X is not easily scratched.

<Comparative Example> Next, a comparative example with the present invention will be described.

As shown in FIG. 9, a developer filling pallet D composed of a bottom plate 210 and a pressing block 200 which have been conventionally used was prepared.

The bottom plate 210 is a metal plate to which a polyacetal resin plate is attached, and the lateral holding block 200 is similarly molded from polyacetal resin.

Using the developer filling pallet D produced as described above, the developer supply container X is filled with the same amount of the developer at the same rate as in the first embodiment. At this point, it was confirmed that the powder surface in the developer supply container X was at the position a in FIG.

Next, in order to carry out the secondary filling, as many developer supply containers X as can be mounted on the vibration plate 100 (see FIG. 3) used in the first embodiment are used for the same time as in the first embodiment. After mounting, the same vibration as that in the first embodiment was applied to the developer supply container X.

Immediately after the vibration, when the powder surface drop inside the developer supply container X was measured, it was not lowered to the position of b in FIG. 6, and therefore the secondary filling amount was the vibration for filling the developer according to the present invention. It was confirmed that the number was smaller than that when the frame A was used.

Further, by changing the vibration time, the distance when the vibrating frame A for filling the developer according to the present invention was used and the distance of the powder surface reduction L were measured and plotted. The result is shown in Figure 1.
It shows in 0.

As is apparent from FIG. 10, when the developer filling pallet D of the comparative example is used, the powder surface at a certain time is compared with the case where the developer filling vibrating frame A according to the present invention is used. The result that the decrease L was inferior was confirmed.

The reason for the above is that the weight of the developer filling pallet D per container X depends on the resin used for the bottom plate 210 and the side pressing block 200, and therefore the developer filling vibrating frame according to the present invention. In addition to being significantly heavier than each frame 15 of the body A and having large vibration damping in the pallet D, in the comparative example, the self-excited vibration of the developer supply container X is completely suppressed by the lateral pressing block 200, and the amplitude of the amplitude is reduced. It is conceivable that amplification cannot be obtained, and therefore the powder surface is more deteriorated when the vibration frame A whose amplitude is amplified by self-excited vibration at the same frequency is used.

Further, in the comparative example and the first embodiment, the number of the developer supply containers X that can be mounted on the diaphragm 100 having the same area is smaller in the comparative example, and the filling cost is increased in the comparative example. The reason is that the bottom plate 21 of the developer filling pallet D of the comparative example.
This is because the area of 0 is larger than the area of each frame 15 of the first embodiment.

Therefore, the developer filling pallet D according to the comparative example is inferior to the present invention in the amount of developer filling which can be filled within a certain period of time, and the area is limited to one area at a time. It is not possible to maximize the number of developer supply containers X that can be mounted on the vibration plate 100 and vibrated, which leads to an increase in filling cost. [Second Invention] An embodiment of the second invention will be described below with reference to the accompanying drawings.

<First Embodiment> FIG. 11 is a perspective view of a developer filling vibrating frame A according to a first embodiment of the present invention. The vibrating frame A includes a vertical frame 10, a horizontal frame 11 and It is configured by combining the bottom plate 13. In addition, the capacity of the vibration device is small,
When the withstand load is small, the bottom plate 13 is omitted and the vertical frame 10
The vibrating frame body A may be configured only by the horizontal frame 11.

In the vibrating frame A, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 constitutes a space into which the developer supply container X shown in FIG. 13 should be inserted. In order to prevent the developer supply container X from rattling therein, its shape and dimensions are set according to the developer supply container X.

By the way, as a method of constructing each of the frames 15, that is, a method of combining the vertical frame 10 and the horizontal frame 11, binding by screws or the like, or as shown in FIG. There is a combination of the formed recesses 18 and the like, and in any method, it is necessary to surely combine the vertical frame 10 and the horizontal frame 11 so that each frame 15 does not rattle due to vibration.

Thus, the vertical frame 10, the horizontal frame 11, and the bottom plate 13
The developer-filling vibrating frame A is composed of a light metal that is as light and thin as possible so that the vibration from below is transmitted to the developer supply container X as it is with as little vibration as possible. . As the light metal, aluminum is desirable in terms of durability and cost.

When the material of the vertical frame 10, the horizontal frame 11 and the bottom plate 13 is aluminum, the thickness thereof is about 1 mm.
About 5 mm is desirable, more preferably 1 mm to 3 mm
Is preferred.

Further, in this embodiment, the holding surface of the developer supply container X of the vibrating frame A for filling the developer constituted by the vertical frame 10, the horizontal frame 11 and the bottom plate 13 is protected with a thickness of 1 mm or less. Layers have been formed. As the protective layer, a plastic film or the like is attached or a resin coating is applied, and preferably a Teflon resin film is applied or a coating is applied by a spray method or the like.

By forming the protective layer, the surface of the vibrating frame A holding the developer supply container X is not easily scratched, and the protective layer has a thickness of 1 mm or less. The vibration is hardly damped in the vibrating frame A.

Next, as shown in FIG. 13, the developer-filling vibrating frame A is securely mounted on and attached to the vibrating plate 100.

The developer-filling vibrating frame A is securely mounted and mounted on the vibrating plate 100, as shown in FIG. When attaching the vibrating frame A, the bottom plate 13 should be completely attached with a double-sided adhesive tape or the like, or vibrated with a screw or the like so that rattling does not occur between the vibrating frame A and the vibration plate 100. Fully fixed to the plate 100.

Next, a high-density filling method of the developer t using the vibrating frame A for filling the developer according to the present invention will be described.

As shown in FIG. 15, the discharge nozzle 5 of the hopper 20 in which the freshly manufactured developer t is stored.
Inside the 0, an auger 51 for discharging the developer t while regulating the discharging speed is provided.

The developer t in the hopper 20 is discharged from the discharge nozzle 50 while being regulated at a constant discharge speed. Then, the developer t discharged from the discharge nozzle 50
Next moves to the funnel 70 having a diameter that matches the diameter of the filling port 2 of the developer supply container X, and finally is discharged from the funnel 70 through the filling port 2 toward the developer supply container X. The supply container X is primarily filled.

As described above, after the primary filling of the developer t is completed, as shown in FIG. 13, the developer supply containers X whose primary filling is completed are sequentially filled with the developer on the vibrating plate 100. Each frame 15 of the vibrating frame body A is loaded one after another.

A vibrating device is attached to the lower portion of the diaphragm 100. As a method of driving the vibration device, there are an air cylinder type vibration method and an electromagnetic type vibration method. The air cylinder type vibration method vibrates the entire diaphragm 100 by regulating the air pressure, but since it is an air type, the frequency and the amplitude simultaneously increase and decrease. On the other hand, in the electromagnetic vibration method, both the frequency and the amplitude can be controlled by using the voltage regulation and the converter together.

Therefore, the electromagnetic vibration method can control the vibration more precisely, and the developer supply container X for the developer t can be controlled.
It is possible to regulate the decrease of the powder surface inside. For example, in FIG.
4 is used, the electromagnetic vibration device Y includes a vibration source body 150, a power switch 80, a frequency conversion knob 60, and an amplitude adjustment knob 90 provided in the outer frame 160. It is configured to include. A vibration gap 110 is formed in the outer frame 160.

Thus, in the above electromagnetic vibrating device Y,
When the power switch 80 is turned on, the alternating current of the frequency adjusted by the built-in converter is applied to the electromagnetic vibration device Y.
The optimum vibration can be obtained by adjusting the amplitude of the flow.

Next, the reduction of the powder surface of the developer t in the developer supply container X will be described.

As shown in FIG. 16, by the primary filling, the developer t is filled up to the position where the powder surface in the developer supply container X is a.

After that, when the developer supplying container X is loaded in the developer filling vibrating frame A on the vibrating plate 100 and vibration is applied thereto, the vibration is generated via the developer filling vibrating frame A. It is transmitted to the supply container X. Due to the vibration of the developer supply container X, the developer t located at the position a immediately after the filling is filled with the developer t.
The powder surface of is lowered to the position of b. The larger the distance L between the powder surface a and the powder surface b, the larger the filling amount of the developer t that can be filled by the secondary filling.

In order to fill the developer supply container X with the developer t in the highest possible density in a short time, it is necessary to make an effort to increase the primary filling amount and the secondary filling amount of the developer t as much as possible. . In particular, the amount of the developer t to be primarily filled may be an amount with which the developer t is filled up to just before the filling port 2 of the developer supply container X, and this amount is regulated by the rotation speed of the auger 51.

By the way, in transmitting almost 100% of the vibration to the developer supply container X, the vibration transmitting performance of the developer filling vibrating frame A according to the present invention is an important factor.

The developer filling vibrating frame A according to the present invention is
As described above, in addition to being as light and thin as possible, it is possible to transmit vibrations to the developer supply container X while suppressing the vibration to a minimum, and as a result of the self-excited vibration of the developer supply container X, A vibration that is further amplified than the transmitted vibration is applied to X, and it is possible to maximize the distance L for lowering the powder surface in the developer supply container X within a fixed time.

Therefore, the developer t is equal to 2 by the amount of the decrease L of the powder surface.
The next filling amount can be increased, which enables the high density filling of the developer t.

The vibrating frame A for filling the developer according to the present invention
Is used, it is possible to increase the number of developer supply containers X that can be mounted and vibrated at a time on the diaphragm 100 having a limited area, and the filling tact of the developer t can be increased to reduce the filling cost. It will be possible.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

As shown in FIG. 17, similarly to the first embodiment, the developer filling vibrating frame B according to the present embodiment has a vertical frame 1
0, the horizontal frame 11, and the bottom plate 13 are combined. As in the first embodiment, when the vibration device has a small capacity and a small withstand load, the bottom plate 13 may be omitted and the vibrating frame body B may be configured by only the vertical frame 10 and the horizontal frame 11. .

In the vibrating frame B, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X is to be inserted. In order to prevent the developer supply container X from rattling, its shape and size are set according to the developer supply container X.

Then, the vertical frame 10 and the horizontal frame 11 of the vibrating frame B are arranged.
As shown in FIG. 17, a lightening portion 19 is formed in each of the parts except the combined parts. This lightening part 19
As a result, the weight of the developer-filling vibrating frame B can be significantly reduced, and vibration damping can be minimized.

The developer-filling vibrating frame B composed of the vertical frame 10, the horizontal frame 11 and the bottom plate 13 is made of a light metal such as aluminum which is as light and thin as possible like the first embodiment. It

Next, as shown in FIG. 18, the developer-filling vibrating frame B is securely mounted and mounted on the vibrating plate 100.

When the developer-filled vibrating frame B mounted on the vibrating plate 100 was used to densely fill the developer with the same density as in the first embodiment. As a result, it was possible to fill at a high density equal to or higher than that, and it was possible to reduce the filling cost by maximizing the number of containers that can vibrate at one time.

The developer-filling vibrating frame B according to the present embodiment achieves a significant reduction in weight by the lightening portion 19 as compared with the developer-filling vibrating frame A used in the first embodiment. Is
It became possible to more effectively minimize the vibration damping.

In particular, this embodiment is extremely useful when the load capacity of the vibration device is small, the number of developer supply containers vibrated at one time is large, or the developer filling amount per container is large. Is effective for.

Further, also in this embodiment, since a protective layer is formed on the holding surface of the vibrating frame B on which the developer supply container X is to be held, the developer supply container X is less likely to be scratched and further protected. Since the layer has a thickness of 1 mm or less, the protective layer hardly damps the vibration.

<Third Embodiment> Next, a third embodiment of the present invention will be described.

Similar to the first embodiment, the developer filling vibrating frame C according to the present embodiment is constructed by combining the vertical frame 10, the horizontal frame 11 and the bottom plate 13. As in the first embodiment, when the vibration device has a small capacity and a small load resistance, the bottom plate 13 may be omitted and the vertical frame 10 and the horizontal frame 11 may constitute the vibration frame body C. .

In the vibrating frame C, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X shown in FIG. 18 should be inserted. The shape and size of the developer supply container X are adjusted to the developer supply container X so that the developer supply container X does not rattle.

By the way, in this embodiment, as shown in FIG. 18, the vertical frame 10 and the horizontal frame 11 are provided with corner cuts 30 for facilitating the loading of the developer supply container X into each frame 15. .

Thus, by the corner removal 30 described above,
An operator or a robot system does not take time to load the developer supply container X, and the surface of the developer supply container X is not easily scratched when the developer supply container X is taken out.

The developer-filling vibrating frame C composed of the vertical frame 10, the horizontal frame 11 and the bottom plate 13 is made of a light metal such as aluminum which is as light and thin as possible, as in the first embodiment. .

The developer-filling vibrating frame A is securely mounted on the vibrating plate 100 as in the first embodiment (see FIG. 13).

Then, the same high-density developer as in the first embodiment was filled using the developer-filling vibrating frame C mounted on the vibrating plate 100, which was the same as in the first embodiment. As described above, the high-density developer can be filled, and the number of containers that can be vibrated at one time can be maximized to reduce the filling cost.

When the vibrating frame C for filling the developer according to the present embodiment is used, the developer is supplied for the corners 30 as compared with the case where the vibrating frame A according to the first embodiment is used. It is very effective because it does not take time to load the container X and the surface of the container X is not easily scratched when the container X is taken out.

Further, as in the first and second embodiments, the holding surface of the developer supply container X held by the protective layer is not easily scratched, and the thickness of the protective layer is 1 mm or less.
Vibration is hardly damped in the vibrating frame C.

<Comparative Example> Next, a comparative example with the present invention will be described.

As shown in FIG. 19, a developer filling pallet D including a conventionally used bottom plate 210 and a pressing block 200 was prepared.

The bottom plate 210 is a metal plate to which a polyacetal resin plate is attached, and the lateral holding block 200 is similarly molded from polyacetal resin.

Using the developer filling pallet D produced as described above, the developer supply container X is filled with the same amount of the developer at the same rate as in the first embodiment.

At this point, it was confirmed that the powder surface in the developer supply container X was at the position a in FIG.

Next, in order to carry out the secondary filling, as many developer supply containers X as can be mounted on the vibration plate 100 (see FIG. 13) used in the first embodiment are provided for the same time as in the first embodiment. After mounting, the same vibration as in the first embodiment was applied.

Immediately after the vibration, the powder surface drop inside the developer supply container X was measured, and it was not lowered to the position of b in FIG. 16. Therefore, the secondary filling amount was It was confirmed that the number was smaller than that when the vibrating frame A was used.

Further, the vibration time was changed and the distance L of powder surface reduction was measured and plotted in the case of using the developer-filling vibration frame A of the present invention and in the powder surface. The result is shown in Figure 2.
It shows in 0.

As is apparent from FIG. 20, the developer filling pallet D according to Comparative Example 1 has a powder surface at a constant time, as compared with the case where the developer filling vibrating frame A according to the present invention is used. The result that the decrease L was inferior was confirmed.

The reason is that the weight of the developer filling pallet D per container X is the resin used for the bottom plate 210 and the side pressing block 200, and therefore the developer filling vibrating frame according to the present invention. In addition to being significantly heavier than each frame 15 of the body A and having large vibration damping in the pallet D, in the comparative example, the self-excited vibration of the developer supply container X is completely suppressed by the lateral pressing block 200, and the amplitude of the amplitude is reduced. It is conceivable that amplification cannot be obtained, and therefore the powder surface deterioration becomes larger when the frame A whose amplitude is amplified by self-excited vibration at the same frequency is used.

Further, in the comparative example 1 and the first example, the number of the developer supply containers X which can be mounted on the vibration plate 100 having the same area is smaller in the comparative example 1, and the comparative example 1 increases the filling cost. The reason for this is that the area of the bottom plate 210 of the developer filling pallet D of Comparative Example 1 is larger than the area of each frame 15 of the first embodiment.

Therefore, the developer filling pallet D of Comparative Example 1 is inferior to the present invention in the developer filling amount that can be filled within a fixed time, and the diaphragm having a limited area at one time is used. It is not possible to maximize the number of developer supply containers X that can be mounted on 100 and vibrated, which leads to an increase in filling cost.

<Comparative Example 2> Next, a second comparative example with the present invention will be described.

The developer-filling vibrating frame E having the same shape and dimensions as in the first embodiment was prepared without forming the protective layer.

Using the developer-filling vibrating frame E produced as described above, the developer supply container X is filled with the same amount of the developer at the same rate as in the first embodiment, and then the container is filled. The same vibration as in the first embodiment was applied to X.

The powder surface reduction L of the developer after vibration for a certain period of time was about the same as in the first embodiment.

After the completion of the filling of the developer, the developer supply container X was removed from the developer filling vibrating frame E, and the appearance was inspected. It was confirmed that there were innumerable small scratches due to rubbing, making it impossible to ship the product. [Third Invention] An embodiment of the third invention will be described below with reference to the accompanying drawings.

<First Embodiment> As shown in FIGS. 21 and 23, a vibrating frame A for filling developer according to the present invention comprises a vertical frame 1
0, a horizontal frame 11, a bottom plate 13, and a metal spring 8.

In the developer filling vibrating frame A, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X shown in FIG. 23 is fitted. Therefore, the shape and size of the frame 15 are set according to the developer supply container X so that the developer supply container X does not rattle therein.

By the way, as a method of constructing each of the frames 15, that is, a method of combining the vertical frame 10 and the horizontal frame 11, binding by screws or the like, or as shown in FIG. There is a combination of the formed recesses 18 and the like, and in any method, it is necessary to surely combine the vertical frame 10 and the horizontal frame 11 so that each frame 15 does not rattle due to vibration.

Thus, the developer-filling vibrating frame A composed of the vertical frame 10, the horizontal frame 11, the bottom plate 13, and the metal spring 8 is used as it is for the development without any damping of vibrations from below. It is made of light metal that is as light and thin as possible so as to be transmitted to the agent supply container X.

As the light metal, aluminum or duralumin having a specific gravity of 4 or less is used, and aluminum is particularly preferable in terms of durability and cost.

If the material of the vertical frame 10, the horizontal frame 11 and the bottom plate 13 is aluminum, the thickness thereof is about 1 mm to 5 mm.
The thickness is preferably about mm, and more preferably 1 mm to 3 mm.

The developer-filling vibrating frame A is securely mounted and mounted on the vibrating plate 100, as shown in FIG. When the vibration frame A is attached, the bottom plate 13 is completely attached with double-sided adhesive tape or the like, or is completely fixed to the vibration plate 100 with screws or the like so as not to cause rattling with the vibration plate 100.

As shown in FIG. 23, on the bottom plate 13, for each frame 15, the metal spring 8 and the groove portion 1 provided in the vertical frame 10 are provided.
4, and a sliding plate 5 that moves up and down in the groove 14 is provided.

The metal spring 8 has a frame 15 on the bottom surface of the bottom plate 13.
They are evenly distributed for each and securely joined by screwing or the like.
The metal spring 8 is a phosphor bronze plate specified by JIS-H3731 and SUS301-CSP, SUS3 specified by JIS.
04-CSP (above austenite type), SUS420
J2-CSP (Martensite system), SUS631-C
It is desirable to use a leaf spring made of metal such as SP (precipitation hardening system), and more desirably a phosphor bronze sheet prescribed in JIS-H3731. The shape of the metal spring 8 may be any shape other than that shown in FIG.

The material of the sliding plate 5 is not particularly limited, such as metal and plastic, but the vibration of the metal spring 8 is not attenuated as much as possible, and the vibration is effectively applied to the bottom of the developer supply container X. It is desirable to use a material that is as light as possible and highly durable so that it can be transmitted to, for example, an aluminum plate having a thickness of about 0.5 mm.

The length of the groove portion 14 is regulated so that the sliding plate 5 does not come out of the groove portion 14 when the amplitude of the sliding plate 5 is too large when the sliding plate 5 moves up and down. It

Here, how vibration is transmitted to the developer supply container X when the metal spring 8 is used will be described.

First, the vibration is transmitted from the diaphragm 100 to the metal spring 8. The amplitude of this vibration is amplified by the spring repulsive force of the metal spring 8. The vibration of the amplified amplitude is transmitted to the sliding plate 5 above the metal spring 8 and further to the bottom of the developer supply container X.

As described above, the vibration amplitude from the vibration plate 100 is amplified by the metal spring 8, but this is very effective especially when the weight of the developer supply container X and the developer t is large. .

Next, a high-density filling method of the developer t using the vibrating frame A for filling the developer according to the present invention will be described.

As shown in FIG. 25, the discharge nozzle 5 of the hopper 20 in which the freshly manufactured developer t is stored.
Inside the 0, an auger 51 for discharging the developer t while regulating the discharging speed is provided.

The developer t in the hopper 20 is discharged from the discharge nozzle 50 at a constant discharge speed. The developer t discharged from the discharge nozzle 50 then moves to the funnel 70 having a diameter that matches the diameter of the filling port 2 of the developer supply container X, and finally passes through the filling port 2 from the funnel 70 to develop. The developer is discharged toward the developer supply container X and is primarily filled in the developer supply container X.

As described above, after the primary filling is completed, as shown in FIG. 23, the developer supply container X whose primary filling is completed is sequentially arranged on the vibrating plate 100 for the developer filling vibrating frame A. The frames 15 are loaded one after another.

A vibrating device is attached to the lower portion of the vibrating plate 100. As a method of driving the vibration device, there are an air cylinder type vibration method and an electromagnetic type vibration method. The air cylinder type vibration method vibrates the entire diaphragm 100 by regulating the air pressure, but since it is an air type, the frequency and the amplitude simultaneously increase and decrease. On the other hand, in the electromagnetic vibration method, both the frequency and the amplitude can be controlled by using the voltage regulation and the converter together.

Therefore, the electromagnetic vibration method can control the vibration more precisely, and the developer supply container X for the developer t can be controlled.
It is possible to regulate the decrease of the powder surface inside. For example, in FIG.
4 is used, the electromagnetic vibration device Y includes a vibration source body 150, a power switch 80, a frequency conversion knob 60, and an amplitude adjustment knob 90 provided in the outer frame 160. It is configured to include. A vibration gap 110 is formed in the outer frame 160.

Thus, in the above electromagnetic vibration device Y,
When the power switch 80 is turned on, the alternating current of the frequency adjusted by the built-in converter is applied to the electromagnetic vibration device Y.
The optimum vibration can be obtained by adjusting the amplitude of the flow.

Next, the reduction of the powder surface of the developer t in the developer supply container X will be described.

As shown in FIG. 26, by the primary filling, the developer t is filled to the position where the powder surface in the developer supply container X is a.

Then, when the developer supplying vibrating frame A on the vibrating plate 100 is filled with the developer supply container X and is vibrated, the vibration is generated via the developer filling vibrating frame A. It is transmitted to the supply container X. Due to the vibration of the developer supply container X, the developer t located at the position a immediately after the filling is filled with the developer t.
The powder surface of is lowered to the position of b. The larger the distance L between the powder surface a and the powder surface b, the larger the filling amount of the developer t that can be filled by the secondary filling.

In order to fill the developer supply container X with the developer t in the highest possible density in a short time, it is necessary to make an effort to increase the primary filling amount and the secondary filling amount of the developer t as much as possible. . In particular, the amount of the developer t to be primarily filled may be an amount with which the developer t is filled up to just before the filling port 2 of the developer supply container X, and this amount is regulated by the rotation speed of the auger 51.

By the way, the amount of the developer to be secondarily filled is substantially determined by the performance of the vibration source main body 150 provided below the vibration plate 100. In transmitting almost 100% of the vibration from the vibration source main body 150 to the developer supply container X, the vibration transmitting performance of the developer filling vibrating frame A according to the present invention is an important factor.

The developer filling vibrating frame A according to the present invention is
As described above, not only is it as light and thin as possible and it is possible to transmit vibrations to the developer supply container X with minimal damping, but also to transmit as a result of self-excited vibration of the developer supply container X. Vibration that is more amplified than
It is possible to maximize the distance L of powder surface reduction in the developer supply container X within a fixed time.

Therefore, the developer t is equal to 2 by the amount of the decrease L of the powder surface.
The next filling amount can be increased, which enables the high density filling of the developer t.

Further, the vibrating frame A for filling the developer according to the present invention
Is used, it is possible to increase the number of developer supply containers X that can be mounted and vibrated at a time on the vibration plate 100 having a limited area, and increase the tact for filling the developer t to reduce the filling cost. Is possible.

Further, in the developer filling vibrating frame A according to the present invention, the vibration amplitude is amplified by the spring repulsive force of the metal spring 8, and especially when the weight of the developer supply container X and the developer t is large. Is very effective for.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

Similar to the first embodiment, the developer-filling vibrating frame B according to the present embodiment has a vertical frame 10, a horizontal frame 11, and a bottom plate 13.
And a metal spring 8.

In the vibrating frame B, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X is fitted, as in the first embodiment. Therefore, the shape and size of the frame 15 are set according to the developer supply container so that the developer supply container X does not rattle therein.

Then, the vertical frame 10 and the horizontal frame 1 of the vibrating frame B are arranged.
As shown in FIG. 27, a lightening portion 19 is formed on the first portion 1 except for the mutually combined portions. This lightening part 19
As a result, the weight of the developer-filling vibrating frame B can be significantly reduced, and vibration damping can be minimized.

The vibrating frame B for filling the developer, which is composed of the vertical frame 10, the horizontal frame 11, the bottom plate 13, and the metal spring 8, is made of aluminum or the like, which is as light as possible and thin, as in the first embodiment. Composed of light metal.

Then, as shown in FIG. 28, the same high density filling of the developer as in Example 1 was performed using the vibrating frame B for filling developer, which was the same as in Example 1. As described above, it is possible to fill the developer with high density, and it is possible to reduce the filling cost by maximizing the number of containers that can vibrate at one time.

The developer-filling vibrating frame B according to the present embodiment is greatly reduced by the lightening portion 19 as compared with the developer-filling vibrating frame A used in the first embodiment. It was achieved, and it became possible to minimize vibration damping more effectively. In particular, it is very effective when the vibration device has a small withstand load, when there are a large number of developer supply containers that are vibrated at one time, or when the developer filling amount per container is large.

<Third Embodiment> Next, a third embodiment of the present invention will be described.

Similar to the first embodiment, the developer filling vibrating frame C according to the present embodiment has a vertical frame 10, a horizontal frame 11, and a bottom plate 13.
And a metal spring 8.

In the vibrating frame C, each frame 15 composed of the vertical frame 10 and the horizontal frame 11 forms a space into which the developer supply container X should be fitted, as in the first embodiment. Thus, the shape and size of the frame 15 are set in accordance with the developer supply container X so that the developer supply container X does not rattle therein.

By the way, in this embodiment, as shown in FIG. 28, the vertical frame 10 and the horizontal frame 11 are provided with corner cuts 30 for facilitating the loading of the developer supply container X into each frame 15. .

Then, by the above corner removal 30,
An operator or a robot system does not take time to load the developer supply container X, and the surface of the container X is not easily scratched when the developer supply container X is taken out.

The developer filling vibrating frame C including the vertical frame 10, the horizontal frame 11, the bottom plate 13 and the metal spring 8 is made of a light metal such as aluminum which is as light as possible and thin as in the first embodiment. Composed.

The developer-filling vibrating frame C is securely mounted and mounted on the vibrating plate 100 as in the first embodiment (see FIG. 23).

When the developer-filled vibrating frame C mounted on the vibrating plate 100 was used to fill the high-density developer in the same manner as in the first embodiment, the result was equal to or higher than that in the first embodiment. High-density developer can be filled, and the number of containers that can be vibrated at one time can be maximized to reduce the filling cost.

The use of the developer-filling vibrating frame C according to the present embodiment provides the corner removal 30 as compared with the case of using the developer-filling vibrating frame A according to the first embodiment. In addition, it does not take time to load the developer supply container X, and when the developer supply container X is taken out, the surface of the container X is hardly scratched, which is very effective.

Comparative Example 1 Next, a first comparative example with the present invention will be described.

As shown in FIG. 29, a pallet D for filling a developer, which is composed of a bottom plate 210 and a pressing block 200 which have been conventionally used, was prepared.

The bottom plate 210 is a metal plate to which a polyacetal resin plate is attached, and the lateral pressing block 200 is similarly molded from polyacetal resin.

Using the developer filling pallet D produced as described above, the developer supply container X is filled with the same amount of the developer t at the same rate as in the first embodiment. At this point, it was confirmed that the powder surface in the developer supply container X was at the position a in FIG.

Next, in order to carry out the secondary filling, as many developer supply containers X as can be mounted on the vibration plate 100 (see FIG. 23) used in the first embodiment for the same time as in the first embodiment. After mounting, the same vibration as that in the first embodiment was applied to the developer supply container X.

Immediately after the vibration, the powder surface drop inside the developer supply container X was measured, and it was found that the powder surface did not reach the position of b in FIG. 26. It was confirmed that the number was smaller than that when the vibrating frame A was used.

Further, the distance L of powder surface reduction when the vibrating frame A for filling the developer and the pallet D according to the present invention were used while varying the vibration time was measured and plotted. The result is shown in FIG.

As is apparent from FIG. 30, the developer filling pallet D according to this comparative example has a powder surface at a certain time, as compared with the case where the developer filling vibrating frame A according to the present invention is used. The result that the decrease L was inferior was confirmed.

The reason for the above is that the weight of the developer-filling pallet D per container X depends on the resin used for the bottom plate 210 and the lateral pressing block 200, so that the developer-filling vibrating frame according to the present invention is used. In addition to being significantly heavier than each frame 15 of the body A and having large vibration damping in the pallet D, in the comparative example, the self-excited vibration of the developer supply container X is completely suppressed by the lateral pressing block 200, and the vibration amplitude is Therefore, it is conceivable that the powder surface is more deteriorated when the frame A whose amplitude is amplified by self-excited vibration at the same frequency is used.

Further, the number of developer supply containers X that can be mounted on the diaphragm 100 having the same area in this comparative example and the first example is smaller in this comparative example, and the filling cost is increased in the comparative example. The reason is that the area of the bottom plate 210 of the developer filling pallet D of the comparative example is larger than the area of each frame 15 of the first embodiment.

Therefore, the developer filling pallet D according to this comparative example is inferior to the present invention in the filling amount which can be filled within a fixed time, and the diaphragm 1 having a limited area at one time.
It is not possible to maximize the number of developer supply containers X that can be shaken by being mounted on the printer 00, which leads to an increase in filling cost.

Comparative Example 2 Next, a second comparative example with the present invention will be described.

As shown in FIG. 31, the vertical frame 10 and the horizontal frame 11
A vibrating frame E for filling the developer, including the bottom plate 13 and the bottom plate 13, was manufactured. That is, the frame E having the same shape and material as those of the first embodiment was manufactured without providing the metal spring.

Using the developer-filling vibrating frame E produced as described above, the developer supply container X is filled with the same amount of the developer t at the same rate as in the first embodiment.

Next, in order to carry out the secondary filling, as many developer supply containers X as can be mounted on the vibration plate 100 used in the first embodiment are loaded for the same time as in the first embodiment, and The same vibration as in the first example was applied to the container X.

Immediately after the vibration, the powder surface drop inside the developer supply container X was measured, and it was not lowered to the position of b in FIG. 26. Therefore, the secondary filling amount is the same as that for the developer filling according to the present invention. It was confirmed that the number was smaller than that when the vibrating frame A was used.

Further, by changing the vibration time, the distance L of the powder surface lowering between the developer-filling vibration frame A according to the present invention and the developer-filling vibration frame E according to the present comparative example was measured, respectively. Turned into The result is shown in FIG.

As is clear from FIG. 32, the vibrating frame E for filling the developer of this comparative example has a powder surface at a certain time, as compared with the vibrating frame A for filling the developer according to the present invention. The results were confirmed to be inferior in decline. The reason for this is that when the developer-filling vibrating frame A according to the present invention is used, the spring repulsive force of the metal spring 8 amplifies the amplitude of the vibration given by the vibrating plate 100. This is because the vibrating force applied to the developer supply container X is larger than in the case of the example, and thus the powder surface reduction in a certain period of time is larger than that in this comparative example.

Therefore, it was revealed that the vibrating frame E for filling the developer of this comparative example is inferior in powder surface reduction as compared with the present invention because the repulsive force of the metal spring cannot be obtained. [Fourth Invention] An embodiment of the fourth invention will be described below with reference to the accompanying drawings.

<First Embodiment> FIG. 33 is a perspective view of a developer filling transport pallet A according to the first embodiment of the present invention.
The transfer pallet A is composed of a bottom plate Z and a lateral pressing block B.

The bottom plate Z is not a plate in which a metal plate and a resin are closely adhered to each other as much as possible so that the vibration from below is mainly transmitted to the developer supply container P as it is in a state where it is not attenuated as much as possible. It is made of light metal that is lightweight and thin. Aluminum is preferable as the light metal in terms of durability and cost.

The side pressing block B is made of a light metal such as aluminum in the same manner as the bottom plate Z in accordance with the shape of the developer supply container P. Similar to the bottom plate Z, the lateral pressing block B has a certain rigidity so that the vibration can be transmitted to the developer supply container P as easily as possible and the developer supply container P does not fall down during transportation. It is made as thin as possible. If the bottom plate Z and the lateral pressing block B are made of aluminum, their thickness is preferably about 1 mm to 3 mm.

By the way, the lateral pressing block B is composed of a fixed block B1 and a movable block B2 as shown in FIG. The fixed block B1 is completely tightly fitted to the bottom plate Z with a screw or the like, and the movable block B2 is movable in the groove portion M provided in the bottom plate Z shown in FIG.
The movable block B2 can move in the X direction and the Y direction while the movement amounts thereof are restricted, as shown in FIG.

Thus, the developer filling transfer pallet A
33 is carried on the carrying path 100 while holding the developer supply container P having the container body 1 and the filling port 2 as shown in FIGS.

Until the developer supply container P is primarily filled with the developer, as shown in FIG. 34, the movable block B2 of the lateral pressing block B ensures that the developer supply container P has no gap. It is temporarily fixed at the position B2 'so that it can be conveyed while being held. When the movable block B2 is temporarily fixed, electromagnets S and N are provided at the ends of the fixed block B1 and the movable block B2 which are in close contact with each other, as shown in FIG.
Furthermore, an electromagnetic changeover switch (not shown) is provided on the bottom plate Z,
Operate the changeover switch to turn on the electromagnets S and N,
Make sure that the ends of both blocks B1 and B2 are in close contact.

When the developer supply container P is primarily filled with the developer, the changeover switch is operated again to turn off the electromagnets S and N.
F is performed to release the close contact between the fixed block B1 and the movable block B2, and the movable block B2 is disengaged from the fixed block B1 to make it movable.

A developer supply container P that is primarily filled with the developer.
Is transported on the transport path 100 while being vibrated while maintaining a gap that is the movement amount of the movable block B2. The gap formed between the movable block B2 and the developer supply container P is developed in consideration of the shape of the developer supply container P, the unevenness of the transport path 100, whether there is a detour point, the transport speed, and the like. The agent supply container P is provided such that it does not come off the pallet A during transportation, and further, the developer t primarily filled from the filling port 2 of the container P does not pop out due to vibration during transportation. It is set to about 5 mm to 30 mm.

In this embodiment, the gap of the side presser block B is provided by the electromagnetic means (electromagnets S, N), but the gap may be provided without any particular limitation such as air type or mechanical type. it can.

By the way, in this embodiment, the carrier pallet A is used.
A protective layer having a thickness of 1 mm or less is formed on the holding surface of the bottom plate Z and the lateral pressing block B for holding the developer supply container P. As the material of the protective layer, it is desirable that the vibration of the developer supply container P is not disturbed as much as possible and that the surface of the developer supply container P is not easily scratched by vibration or the like. Specifically, the protective layer is preferably a plastic film or the like attached or a resin applied, and more preferably a Teflon resin film applied or applied by a spray method or the like.

By the protective layer, the holding surface of the developer supply container P is less likely to be scratched, and the vibration is propagated to the container P with almost no damping.

Next, a high-density filling method of the developer t using the developer filling transport pallet A according to the present invention will be described.

As shown in FIG. 38, the discharge nozzle 5 of the hopper 20 in which the freshly manufactured developer t is stored.
Inside 0, an auger 51 for discharging the developer t while controlling the discharging speed is provided.

The developer t in the hopper 20 is discharged from the discharge nozzle 50 at a constant discharge speed. Then, the developer t discharged from the discharge nozzle 50 moves to the funnel 70 having a diameter that matches the diameter of the filling opening 2 of the developer supply container P, and finally passes through the filling opening 2 from the funnel 70 to develop. The toner is discharged toward the developer supply container P and is primarily filled in the developer supply container P.

By the way, before the primary filling, a gap is not provided between the lateral pressing block B and the developer supply container P, and when the primary filling is performed, the filling port 2 of the developer supply container P is opened. Be sure to fix it to the funnel 70 while filling.
As a result, it is possible to prevent the developer t from being scattered to the periphery during filling as much as possible.

As described above, after the primary filling of the developer t is completed, as shown in FIG. 37, the developer supply container P whose primary filling is completed is sequentially transported on the transport path 100.

A vibrating device is attached to the lower part of the transport path 100. As a method of driving the vibration device, there are an air cylinder type vibration method and an electromagnetic type vibration method. The air cylinder type vibration method vibrates the entire conveyance path 100 by regulating the air pressure. However, since it is an air type, the frequency and amplitude simultaneously increase and decrease. On the other hand, in the electromagnetic vibration method, both the frequency and the amplitude can be controlled by using the voltage regulation and the inverter together.

Therefore, the electromagnetic vibration method can control the vibration more precisely, and the developer supply container P for the developer t can be controlled.
It is possible to regulate the decrease of the powder surface inside.

Next, a description will be given of the reduction of the powder surface of the developer t in the developer supply container P.

As shown in FIG. 39, by the primary filling, the developer t is filled up to the position where the powder surface in the developer supply container P is a.

Thereafter, the developer supply container P is moved to the transport path 100.
The vibration is transmitted to the developer supply container P via the developer-filling transport pallet A by passing through. Due to this vibration, the powder surface of the developer t which was at the position a immediately after the filling is lowered to the position b. The larger the distance L between the powder surface a and the powder surface b, the larger the filling amount of the developer t that can be filled by the secondary filling.

In order to fill the developer supply container P with the developer t at a high density in a short time, it is necessary to make an effort to increase the primary filling amount and the secondary filling amount as much as possible. In particular, the amount of the developer t to be primarily filled may be an amount with which the developer t is filled up to just before the filling port 2 of the developer supply container P, and this amount is regulated by the rotation speed of the auger 51.

On the other hand, the amount of the developer to be secondarily filled is determined by the performance of the vibration device provided below the conveying path 100. In order to reliably transmit the vibration from the vibrating device to the developer supply container P, the vibration transmitting performance of the developer filling transport pallet A according to the present invention is an important factor.

Transport pallet A for filling developer according to the present invention
In the above, after the primary filling of the developer t, the lateral pressing block B
Since a gap is provided between the developer supply container P and the developer supply container P, self-excited vibration of the developer supply container P is promoted, and as a result, the vibration amplitude from the vibration device is not only compensated for but also transmitted. The vibration amplitude can be increased.

When the vibration frequency is the same, the larger the vibration amplitude is, the more advantageous it is to reduce the powder surface of the developer. It is clear from FIG. 40 which is a graph showing the correlation with the decrease in the powder surface of the developer in the container.

[0248]

## EQU1 ## F = (M ₀ + M ₁ + M ₂ + M ₃ ) × α × D × f ² where, F = exciting force M ₀ = weight of movable part of vibration device M ₁ = mounting jig and table M ₂ = Weight of developer supply container M ₃ = Weight of developer D = Amplitude f = Frequency α = Intrinsic coefficient Therefore, when the developer filling transport pallet A according to the present invention is used, It is possible to give a limited vibration amplitude, and as a result, it becomes possible to maximize the distance L of the powder surface reduction in the developer supply container P within a fixed time. That is, the secondary filling amount of the developer t can be increased by the amount L of the powder surface reduction, and the high density filling of the developer t can be performed.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

The developer filling transfer pallet C according to the present embodiment is similar to the first embodiment in that the bottom plate Z and the lateral pressing block B are used.
And is manufactured in the same shape as the first embodiment.

The material of the bottom plate Z and the lateral pressing block B is made of a resin material such as polyacetal resin, Teflon resin, ABS resin or the like, which is unlikely to scratch the developer supply container P and is unlikely to be cracked by vibration. It

Therefore, according to this embodiment, unlike the first embodiment, it is not necessary to further provide a protective layer.

The developer filling transfer pallet C according to the present embodiment is provided with a movable side pressing block as in the first embodiment after the primary charging of the developer, and the shape and transfer of the developer supply container P are carried out. An appropriate gap can be maintained between the developer supply container P and the developer supply container P in consideration of the condition of the path, the transport speed, and the like.

Further, the transport pallet C according to this embodiment is
Although it has the same shape as that of the first embodiment, it is made of a resin material having a smaller specific gravity than that of the first embodiment, so that vibration damping from the vibration device is very small.

Therefore, the self-excited vibration of the developer supply container P can be further promoted and the container P can be increased by increasing the vibration amplitude.
The amount of decrease in the powder surface of the developer can be made larger than that in the first embodiment, and as a result, the secondary filling amount of the developer is increased, and the dense filling of the developer becomes possible.

<Third Embodiment> Next, a third embodiment of the present invention will be described.

As shown in FIG. 41, the developer filling transfer pallet D according to the present embodiment has a bottom plate Z as in the first embodiment.
And a lateral presser block B. As the material of the bottom plate Z and the lateral pressing block B, the same resin material as in the second embodiment is selected.

Therefore, according to the present embodiment, as in the second embodiment, it is not necessary to provide a protective layer for preventing the developer supply container P from being damaged by vibration or the like.

The bottom plate Z of the transport pallet D according to this embodiment.
41 has a shape similar to that of the second embodiment, but as shown in FIG. 41, in the lateral pressing block B, the lightening portion 19 is formed in the block having the same shape as that of the second embodiment. By the lightening portion 19, the weight of the lateral pressing block B is significantly reduced, and the weight of the transport pallet D itself is also reduced.

The carrying pallet D according to the present embodiment is provided with a movable side-holding block after the primary filling of the developer as in the first and second embodiments, and the shape of the developer supply container P and the carrying path. In consideration of the state, the transportation speed, etc., it is possible to maintain an appropriate gap with the container P.

Further, the transport pallet D according to this embodiment is
As in the case of the second embodiment, in addition to being made of a lightweight resin material, the weight reduction portion 19 makes it possible to significantly reduce the weight, so that the vibration damping from the vibration device is very small.

Therefore, the self-excited vibration of the developer supply container P can be further accelerated, and the container P can be increased by increasing the vibration amplitude.
The amount of decrease in the powder surface of the developer can be increased more than in the second embodiment, and as a result, the secondary filling amount of the developer is increased, and the high density filling of the developer becomes possible.

<Fourth Embodiment> Next, a fourth embodiment of the present invention will be described.

As shown in FIG. 42, the developer filling transport pallet E according to this embodiment is composed of a bottom plate Z and a lateral pressing block B, as in the first embodiment. The bottom plate Z and the lateral pressing block B are made of a light metal such as aluminum as in the first embodiment.

The bottom plate Z of the transport pallet E according to the present invention is
Although it has the same shape as the first embodiment, as shown in FIG. 42, a corner cut 30 is formed at the upper end of the inner side surface of the side presser block B.
Are formed. The location where the corner removal 30 is provided is the most frequent contact point between the transport pallet E and the developer supply container P when the developer supply container P is transported while vibrating, and the developer supply container P is also provided. Since the surface of the container P is most likely to be damaged during the attachment / detachment, a curved surface formed by the corner cut 30 is provided here to prevent the damage as much as possible.

Further, in the carrier pallet E according to this embodiment, there is no gap between the pallet E and the developer supply container P before the primary filling of the developer, and when the container P is mounted. The corner removal 30 facilitates mounting.

Further, the transport pallet E according to this embodiment maintains a proper gap between the developer P and the developer supply container P after the primary filling of the developer, and thus the container P Self-excited vibration is promoted, and the amount of decrease in the powder surface of the developer can be increased by increasing the vibration amplitude. That is, the secondary filling of the developer is possible by the amount of decrease in the powder surface, and the high-density filling of the developer is realized.

Comparative Example 1 Next, a first comparative example with the present invention will be described.

With the same material and size as in the first embodiment,
A developer filling transport pallet F including a bottom plate Z and a lateral pressing block B was prepared.

The bottom plate Z has the same shape as that of the first embodiment, but unlike the first embodiment, the lateral pressing block B does not have a movable block and is completely shaped according to the shape of the developer supply container P. It is manufactured so that there is no gap with the container P.

Using the developer filling transport pallet F prepared as described above, the developer supply container P is filled with the same amount of the developer t at the same speed as in the embodiment. At this point, it was confirmed that the powder surface in the developer supply container P was at the position a in FIG.

Next, in order to carry out the secondary filling of the developer t,
The developer supply container P was transported while applying the same vibration on the transport path 100 used in the first embodiment.

Immediately after the conveyance, the powder level inside the developer supply container P was measured, and it was not lowered to the position of b in FIG. 39. Therefore, the secondary filling amount is the conveyance for the developer filling according to the present invention. It was confirmed that the amount was smaller than that in the case where the pallet A was used. Further, by changing the vibration time, the developer filling transport pallet A according to the present invention and the pallet F according to the present comparative example.
Measure the distance L of powder surface reduction when using
Graphed. The result is shown in FIG.

As is apparent from FIG. 43, in the case of using the developer filling transport pallet F according to this comparative example, as compared with the case of using the developer filling transport pallet A according to the present invention, It was confirmed that the powder surface deterioration L at a certain time was inferior. The reason for this is that in this comparative example, the self-excited vibration of the developer supply container P after the primary filling is completely suppressed by the lateral pressing block B, and the vibration amplitude cannot be amplified.
This is because the powder surface deterioration was larger in the first embodiment in which the amplitude was amplified by self-excited vibration at the same frequency. That is, the developer-filling transport pallet F according to the present comparative example cannot secure a predetermined amount of the secondary-filled or tertiary-filled developer, making it impossible to densely fill the developer. Become.

<Comparative Example 2> Next, a second comparative example of the present invention will be described.

With the same material and size as in the first embodiment,
A developer filling transport pallet G including a bottom plate Z and a lateral pressing block B was prepared.

The bottom plate Z has the same shape as that of the first embodiment, but the lateral pressing block B does not have a movable block unlike the first embodiment, and the developer supply container P and the block B are preliminarily used in the embodiment. It is manufactured with a set gap.

Using the developer filling transport pallet G prepared as described above, the developer supply container P was filled with the same amount of the developer t at the same rate as in the first embodiment.

However, when carrying out the primary filling, the transfer pallet G
Since the gap between the developer supply container P and the developer supply container P is provided in advance, the self-excited vibration of the container P immediately before filling cannot be suppressed, and the filling port 2 of the container P is securely fixed to the funnel 70. Meanwhile, the developer could not be filled. This allows
The scattering of the developer t around the filling port 2 at the time of filling is extremely large,
By the time of the secondary filling, it was necessary to frequently clean the transport path 100 due to the dirt of the developer.

Further, not all of the developer t to be primarily filled is filled in the developer supply container P through the filling port 2, the amount scattered to the periphery is wasted, and the filling cost is increased. In other words, the developer filling transport pallet G according to the present comparative example cannot be filled 100% of the filling amount that should be primarily filled, and the surrounding dirt due to the scattering of the developer t also overlaps and is filled. The cost will increase. [Fifth Invention] An embodiment of the fifth invention will be described below with reference to the accompanying drawings.

<First Embodiment> As shown in FIG. 44, the developer filling transport pallet A according to the first embodiment of the present invention is
It is composed of a bottom plate 11 and a lateral pressing block 10.

In the transfer pallet A, the bottom plate 11 is a conventional plate in which a metal plate and a resin are adhered to each other so that the vibration from the bottom is transmitted to the developer supply container X as it is without being damped as much as possible. It is made of light metal, which is as light as possible and thin. As a light metal,
Aluminum is desirable in terms of durability and cost.

The horizontal pressing block 10 is composed of the bottom plate 1
Similar to 1, light metal such as aluminum is used for the developer supply container X
It is manufactured according to the shape of. This side presser block 10
Is as similar to the bottom plate 11 as possible to easily transmit the vibration to the developer supply container X, and to the extent that the developer supply container X has a certain rigidity so that the developer supply container X does not fall down during transportation. It is made thin. If the bottom plate 11 and the lateral pressing block 10 are made of aluminum, their thickness is preferably about 1 mm to 3 mm.

By the way, in this embodiment, a protective layer having a thickness of 1 mm or less is formed on the holding surface of the developer supply container X of the bottom plate 11 and the lateral pressing block 10. As the protective layer, a plastic film or the like is applied or a resin coating is applied, and preferably a Teflon resin film is applied or is coated by a spray method or the like.

Thus, the protective layer prevents the holding surface of the developer supply container X from being easily scratched, and since the protective layer has a thickness of 1 mm or less, vibration is hardly damped.

The lateral pressing block 10 is the developer supply container X.
The bottom plate 11 is completely fitted tightly with screws so that there is no play.

The bottom plate 10 and the lateral pressing block 11 may be integrally molded from aluminum or the like.

Next, a high-density filling method of the developer t using the developer filling transport pallet A according to the present invention will be described.

As shown in FIG. 45, the discharge nozzle 5 of the hopper 20 in which the freshly manufactured developer t is stored.
Inside 0, an auger 51 for discharging the developer t while controlling the discharging speed is provided.

The developer t in the hopper 20 is discharged from the discharge nozzle 50 at a constant discharge speed. The developer t discharged from the discharge nozzle 50 then moves to the funnel 70 having a diameter that matches the diameter of the filling port 2 of the developer supply container X, and finally passes through the filling port 2 from the funnel 70 to develop. The developer is discharged toward the developer supply container X and is primarily filled in the developer supply container X.

As described above, after the primary filling of the developer t is completed, as shown in FIG. 48, the developer supply container X whose primary filling is completed is sequentially transported on the transport path 100.

A vibrating device is attached to the lower part of the transport path 100. As a method of driving the vibration device, there are an air cylinder type vibration method and an electromagnetic type vibration method. The air cylinder type vibration method vibrates the entire conveyance path 100 by regulating the air pressure, but since it is an air type, the frequency and amplitude simultaneously increase and decrease. On the other hand, in the electromagnetic vibration method, by using the voltage regulation and the inverter together,
Both frequency and amplitude can be controlled.

Therefore, the electromagnetic vibration method can control the vibration more precisely, and the developer supply container X for the developer t can be controlled.
The powder surface inside is filled up to the position of a in FIG. 47.

Next, the reduction of the powder surface of the developer t in the developer supply container X will be described.

As shown in FIG. 47, by the primary filling, the developer t is filled up to the position where the powder surface in the developer supply container X is a.

Thereafter, the developer supply container X is moved to the transport path 100.
By passing through, the vibration from the vibration device is transmitted to the developer supply container X via the developer filling transport pallet A. By the developer supply container X being vibrated,
Immediately after the filling, the powder surface of the developer t, which was at the position a in FIG. 47, is lowered to the position b. In this case, the larger the distance L between the powder surface a and the powder surface b, the larger the filling amount of the developer t that can be filled by the secondary filling.

In order to fill the developer supply container X with the developer t at a high density in a short time, it is necessary to make an effort to increase the primary filling amount and the secondary filling amount of the developer t as much as possible. . In particular, the amount of the developer t to be primarily filled may be the amount to which the developer t is filled to just before the filling port 2 of the developer supply container X, and this amount is regulated by the rotation speed of the auger 51.

On the other hand, the amount of the developer t to be secondarily filled is determined by the performance of the vibration device provided in the lower portion of the transport path 100. In transmitting almost 100% of the vibration from the vibrating device to the developer supply container X, the vibration transmitting performance of the developer filling transport pallet A according to the present invention is an important factor.

Transport Palette A for Filling Developer According to the Present Invention
As described above, since it is possible to transmit the vibration to the developer supply container X while suppressing the vibration to the minimum attenuation as much as possible, it is possible to reduce the distance L of the powder surface reduction in the developer supply container X. It is possible to maximize the size within a fixed time. Therefore, the secondary filling amount can be increased by the amount L of the powder surface reduction, and the developer t can be filled at a high density.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

The developer filling transfer pallet B according to this embodiment is made of the same material as that of the first embodiment and has the same shape.

Also in this embodiment, as in the first embodiment, the developer t whose discharge speed is regulated is discharged from the hopper 20 through the funnel 70 into the developer supply container X for primary filling.

As described above, the developer supply container X is temporarily stored on the vibration plate 200 as shown in FIG. 48 after the primary filling of the developer is completed and is given a vibration.

A vibrating device is attached to the lower portion of the diaphragm 200. The first driving method of the vibration device is
Similar to the embodiment, there are an air cylinder type vibration method and an electromagnetic type vibration method, but the electromagnetic type vibration method can control the vibration more precisely.

Next, the reduction of the powder surface of the developer t in the developer supply container X will be described.

Similar to the first embodiment, the powder surface of the developer t is at the position a in FIG. 47 immediately after the primary filling, but the developer supply container X is temporarily stored on the vibration plate 200. As a result, the vibration from the vibration device causes the developer loading transfer pallet B
Is transmitted to the developer supply container X via. Then, as the developer supply container X is subjected to vibration, a
The powder surface of the developer t in the position of is lowered to the position of b (see FIG. 47). The amount of the developer t that can be secondarily filled is determined by increasing the distance L between the powder surfaces a and b as much as possible.

The developer filling transport pallet B according to the present embodiment is light and thin as in the first embodiment, and since vibration can be transmitted to the developer supply container X as it is with almost no vibration damping, High density packing of the developer t is possible.

Further, since the carrier pallet B has the protective layer formed thereon, the holding surface of the developer supply container X is not easily scratched, and the protective layer has a thickness of 1 mm or less. Does not decay.

Comparative Example 1 Next, a first comparative example with the present invention will be described.

A developer filling transport pallet C having the same shape and size as in the first embodiment and having the conventionally used structure was prepared as follows.

The bottom plate 11 is formed by sticking a polyacetal resin plate on a metal plate, and the lateral holding block 10 is similarly molded of polyacetal resin.

Using the developer filling transport pallet C prepared as described above, the developer supply container X is filled with the same amount of the developer t at the same rate as in the embodiment. At this point, it was confirmed that the powder surface in the developer supply container X was at the position a in FIG.

Next, in order to carry out the secondary filling of the developer t,
The developer supply container X was transported while applying the same vibration on the transport path 100 used in the first embodiment (see FIG. 46).

Immediately after the conveyance, the powder surface drop inside the developer supply container X was measured, and it was not lowered to the position b in FIG. 47. Therefore, the secondary filling amount of the developer t is the developer according to the present invention. It was confirmed that the number was smaller than that when the filling transport pallet A was used. Further, the vibration time was changed, and the distance L of powder surface reduction when the developer filling transport pallet A according to the present invention and the pallet C according to this comparative example were used was measured and plotted. The result is shown in FIG. 49.

As is apparent from FIG. 49, the developer filling transport pallet C according to this comparative example has a reduced powder surface compared to the case where the developer filling transport pallet A according to the present invention is used. The result that L was inferior was confirmed. That is, it was revealed that the developer filling transport pallet C according to this comparative example is inferior to the present invention in the developer filling amount that can be filled within a fixed time.

<Comparative Example 2> Next, a second comparative example with the present invention will be described.

A developer filling transfer pallet D having the same shape and size as in the second embodiment and having the following conventional structure is prepared.

The bottom plate 11 is formed by sticking a polyacetal resin plate on a metal plate, and the lateral pressing block 10 is similarly molded of polyacetal resin.

Using the developer filling transport pallet D prepared as described above, the developer supply container X is filled with the same amount of the developer t at the same speed as in the embodiment. At this point, it was confirmed that the powder surface in the developer supply container X was at the position a in FIG.

Next, in order to carry out the secondary filling of the developer t,
The developer supply container X was transported while applying the same vibration on the transport path 200 used in the first embodiment (see FIG. 48).

Immediately after the conveyance, the powder surface drop inside the developer supply container X was measured, and it was not lowered to the position b in FIG. 47. Therefore, the secondary filling amount is the developer filling conveyance pallet according to the present invention. It was confirmed that the amount was smaller than that when B was used. Furthermore, the vibration time was changed, and the distance L of powder surface reduction when the developer-filling transport pallet B according to the present invention and the transport pallet D according to this comparative example were used was measured and plotted. The result is shown in FIG.

As is apparent from FIG. 50, in comparison with the case where the developer-filling transport pallet B according to the present invention is used, the developer-filling transport pallet D according to this comparative example has a reduced powder surface at a certain time. The result that L was inferior was confirmed. That is, it was revealed that the developer filling transport pallet D according to the present comparative example is inferior to the present invention in the developer filling amount that can be filled within a fixed time.

<Comparative Example 3> Next, a third comparative example of the present invention will be described.

With the same shape and size as in the first embodiment, the developer-filling transfer pallet E is made of aluminum alone.

Using the developer filling transport pallet E prepared as described above, the developer supply container X is filled with the same amount of the developer t at the same speed as in the first embodiment, and then the developer is filled. The supply container X was conveyed while being subjected to the same vibration as in the first embodiment.

After the conveyance, the powder surface decrease L of the developer t at a constant time was about the same as in the first embodiment.

After the completion of the filling, the developer supply container X was removed from the transport pallet E and the appearance was inspected.
It was confirmed that the surface had numerous scratches due to rubbing against the transport pallet E, making it impossible to ship the product.

<Comparative Example 4> Next, a fourth comparative example with the present invention will be described.

A developer-filling transfer pallet F is made of aluminum alone with the same shape and size as in the second embodiment.

Using the developer filling transport pallet F prepared as described above, the developer supply container X is filled with the same amount of the developer t at the same rate as in the second embodiment, and then the developer is filled. The supply container X was conveyed while applying the same vibration as in the second embodiment.

The decrease L in the powder surface during a certain period of time after the conveyance of the developer t was about the same as in the second embodiment.

After the completion of the filling, the developer supply container X was removed from the transport pallet F and the appearance was inspected.
It was confirmed that the surface had numerous scratches due to rubbing against the transport pallet F, and it became impossible to ship the product. [Sixth Invention] An embodiment of the sixth invention will be described below with reference to the accompanying drawings.

<First Embodiment> As shown in FIG. 51, the developer filling funnel A according to the first embodiment of the present invention is mounted at the positions of the developer discharge receiving portion 1 and the mounting portion 4. It is composed of a developer pouring portion 2 and a processing surface 3 inside the funnel A.

The developer discharge receiving portion 1 has a conical shape so that the developer discharged from the developer hopper (not shown) receives the frictional resistance as much as possible and drops into the developer pouring portion 2 of the funnel A. Alternatively, a shape in which the cylindrical portion 7 and the conical portion 8 are combined as shown in FIG. 51 is desirable.

The developer discharge receiving portion 1 is not deformed by the discharge pressure of the developer discharged from the developer hopper,
In addition, it is made of a metal having wear resistance and rust resistance, and stainless steel is preferable.

The developer pouring portion 2 is formed in a cylindrical shape whose inner diameter is as close as possible to the outer diameter of the filling port of the developer supply container. Then, like the developer discharge receiving portion 1, the developer pouring portion 2 is made of a metal that is not deformed by the discharge pressure and has abrasion resistance and rust prevention. As the metal, for example, stainless steel is desirable, and its wall thickness is desirably as thin as possible. The reason is that the inner diameter d (see FIG. 52) of the developer pouring portion 2 needs to be expanded as much as possible so that the passing developer t is not blocked by the developer pouring portion 2.
This is because it is necessary to make the outer diameter of the funnel A as small as possible when the vicinity of the filling port of the developer supply container is not completely open. When the developer pouring portion 2 is made without slender material, its thickness is preferably about 0.5 mm to 1 mm.

The developer pouring portion 2 is attached to the attachment portion 4 of the conical portion 8 of the developer discharge receiving portion 1 so as to be parallel to the center line of the funnel A.

Developer inflow section 2 and developer discharge receiving section 1
The TIG welding method or the like is used as the connection method, but the connection method is not particularly limited.

In this embodiment, the developer pouring portion 2 and the developer discharge receiving portion 1 are joined to form the funnel A. However, when the length of the funnel is restricted due to the design of the funnel, stainless steel or the like is used. It is also possible to directly carve out the metal of the above to produce the funnel.

[0340] Developer inflow portion 2 and developer discharge receiving portion 1
After joining, the joining portion inside the funnel A is ground particularly at the center.

Then, the polished inner surface of the funnel A is subjected to fluorine treatment.

As the fluororesin used for the fluorine treatment, polytetrafluoroethylene, tetrafluoroethylene = perfluoroalkyl vinyl ether copolymer,
Tetrafluoroethylene = hexafluoropropylene copolymer, polychlorotrifluoroethylene, tetrafluoroethylene = ethylene copolymer, polyvinylidene fluoride, polyvinyl fluoride and the like are used, and preferably polytetrafluoroethylene is used.

Fluorine treatment is carried out by applying a fluororesin by a spray method or a brush, and then at about 150 ° C to 2 ° C.
The treatment is performed by drying at a temperature of about 50 ° C., or by a lining method.

When the fluororesin is applied by a coating method, care should be taken to prevent defects such as foreign matter and film thickness unevenness from occurring on the applied surface and to keep the treated surface 3 as smooth as possible.

The film thickness of the treated surface 3 is 0.5 mm or more in consideration of the fact that the fluorine treated surface is gradually scraped due to friction with the developer.
It is set to about 1.5 mm.

As shown in FIG. 53, when the developer particles t'pass through the treated surface 3 prepared as described above, the fluorine treatment reduces the frictional resistance between the developer particles t'and the treated surface 3. As a result, the developer funnel is less likely to be blocked.

Next, a method of filling the developer t using the developer filling funnel A according to the present embodiment will be described.

As shown in FIG. 54, the developer t which has just been manufactured is supplied from the hopper supply port 10 to the developer hopper 11.
Shipped to and stored in.

The developer t temporarily stored in the developer hopper 11 is discharged from the developer hopper 11 by the rotation of the auger 30 provided in the auger casing 20 provided under the hopper 11. At this time, the discharge speed of the developer t can be easily regulated by controlling the screw rotation speed of the auger 30.

Thus, the developer t discharged from the auger 20 passes through the developer filling funnel A and is filled in the developer supply container X through the filling port 50.

When the developer filling funnel A according to the present embodiment is used, the friction resistance between the developer t and the inner surface of the funnel A is reduced by the fluorine treatment, so that the funnel clogging of the developer t is less likely to occur. . Therefore, the discharge speed of the developer t from the developer hopper 11 can be increased to the extent that the developer t is not blocked by the funnel, and the filling cost can be significantly reduced.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

The developer filling funnel B according to the present embodiment is
Similar to the first embodiment, it is composed of the developer discharge receiving portion 1, the developer pouring portion 2 attached to the position of the attaching portion 4, and the processing surface 3 inside the funnel B.

The material and shape of the developer filling funnel B are the same as those in the first embodiment except the treated surface 3.

In this embodiment, the inner surface of the developer filling funnel B is treated with silicon. In the silicon treatment, a silicone resin is applied by a spray method or a brush, and the applied silicone resin is about 100 ° C.
It is dried at a temperature of about 200 ° C. When applying the silicone resin, it is necessary to pay attention so that defects such as foreign matter and application unevenness do not occur on the application surface, and the processing surface 3 is kept as smooth as possible. Also, the film thickness to be applied is
Considering that the siliconized surface is gradually scraped due to friction with the developer, it is set to a value that ensures a dry film thickness of 0.5 mm to 1.5 mm.

As shown in FIG. 53, when the developer particles t'pass through the processed surface 3 produced as described above, the frictional resistance between the developer particles t'and the processed surface 3 is reduced by the silicon treatment, Therefore, the funnel clogging of the developer is less likely to occur. Therefore, the discharge speed of the developer t from the developer hopper 10 can be increased to such an extent that the developer does not clog the funnel, and the filling cost can be significantly reduced.

<Third Embodiment> Next, a third embodiment of the present invention will be described.

The developer filling funnel C of the present invention has the developer discharge receiving portion 1, the developer pouring portion 2 attached at the position of the attaching portion 4, and the inside of the funnel C as in the first embodiment. And the processing surface 3.

The material and shape of the developer filling funnel C are the same as those in the first embodiment except for the treated surface 3.

In this embodiment, the inner surface of the developer-filling funnel C is treated with ultra-high molecular weight polyethylene.

Ultra-high molecular weight polyethylene has a molecular weight of 300
Since it is more than 10,000, the α chain length of the constituent molecule is very long, and since it is linear, it has excellent wear resistance or impact resistance. In particular, it has impact resistance superior to steel and polyurethane and has self-lubricating properties.
The ultra high molecular weight polyethylene treatment is performed by a lining method.

When performing lining, it is necessary to perform lining so that defects such as foreign matter and coating unevenness do not occur on the lining surface, and care should be taken to keep the treated surface 3 as smooth as possible. The film thickness of the lining is set to a value such that a dry film thickness of about 0.5 mm to 1.5 mm is secured in consideration of the fact that the siliconized surface is gradually scraped due to friction with the developer.

As shown in FIG. 53, when the developer particles t'pass through the treated surface 3 prepared as described above, the developer particles t'and the treated surface 3 are treated by ultra-high molecular weight polyethylene treatment.
The frictional resistance with respect to the developer was reduced, and as a result, the developer funnel was less likely to be blocked. Therefore, the discharge speed of the developer t from the developer hopper 10 can be increased to such an extent that the developer does not clog the funnel, and the filling cost can be significantly reduced.

<Comparative Example> Next, a comparative example with respect to the present invention will be described.

As shown in FIG. 55, the developer discharge receiving portion 1
The developer pouring portion 2 was attached to the position of the attaching portion 4 to prepare a developer filling funnel D. The developer filling funnel D has the same shape and material as those of the first embodiment and has no processing surface.

When the funnel D according to this comparative example and the funnels A, B and C according to the present invention are used respectively, and the developer t having the same physical properties is filled in the developer supply container X,
When the discharge speed of the developer from the developer hopper is increased to the maximum extent that does not cause the funnel clogging, according to the developer filling funnels A, B, and C according to the present invention, the development according to the comparative example is performed. It was possible to speed up the developer by about 3 times or more than the developer discharging speed when the agent filling funnel D was used.

The reason for the above is that the inner surface of the developer-filling funnel D according to the comparative example is not subjected to any surface treatment for reducing the frictional resistance with the developer, so that the inner portion of the funnel D is not treated. This is because the developer temporarily accumulates.

Therefore, when the developer filling funnel D according to the comparative example is used, the filling cost is significantly increased as compared with the case where the developer filling funnels A, B and C according to the present invention are used. have done. [Seventh Invention] An embodiment of the seventh invention will be described below with reference to the accompanying drawings.

<First Embodiment> As shown in FIG. 56, the developer filling funnel A according to the first embodiment of the present invention is mounted at the positions of the developer discharge receiving portion 1 and the mounting portion 4. And a developer pouring section 2.

In the developer filling funnel A, the developer discharge receiving portion 1 receives the developer t discharged from the developer hopper as little frictional resistance as possible, and the developer discharging portion 2 of the funnel A flows into the developer flowing portion 2. Cone to fall or fig. 5
It is desirable to form the cylindrical portion 7 and the conical portion 8 in a combined shape as shown in FIG.

Further, the developer discharge receiving portion 1 is made of a metal which is not deformed by the discharge pressure of the developer t discharged from the developer hopper and has abrasion resistance and rust prevention property, and is made of, for example, stainless steel. It is desirable to be configured.

On the other hand, the developer pouring portion 2 is formed into a cylindrical shape whose inner diameter d is set as close as possible to the outer diameter of the filling port of the developer supply container. The developer pouring part 2 is made of a metal that is not deformed by the discharge pressure like the developer discharge receiving part 1 and has abrasion resistance and rust prevention,
For example, it is preferably made of stainless steel.

By the way, it is desirable that the thickness of the developer pouring portion 2 is as thin as possible. The reason is that it is necessary to widen the inner diameter d of the developer pouring portion 2 so that the passing developer t is not blocked by the developer pouring portion 2.
This is because if the vicinity of the filling port of the developer supply container is not completely open, it is necessary to make the outer diameter of the funnel A as small as possible. In addition, when the developer pouring portion 2 is made without slender material, the thickness thereof is 1 mm to 0.5 mm.
About mm is desirable.

Thus, the inclination angle θ1 of the developer discharge receiving portion 1
And θ2 are 45 ° or more and 90 ° or less, and more preferably 60 ° or more and 90 ° or less. Incidentally, the inclination angles θ1 and θ
When 2 is less than 45 °, the powder pressure of the developer t or the like is easily received, and the powder is temporarily accumulated on the slope, and as a result, the phenomenon that the funnel is closed near the mounting portion 4 is likely to occur.

Further, as shown in FIG. 57, the inclination angles θ1 and θ2 of the funnel A are not the same, but the funnel A is asymmetrical and has a double stop.

By the way, as shown in FIG. 56, how the developer particles t ′ move after hitting the slope 9 on the θ1 side and how the developer particles t ″ move after hitting the slope 9 ′ on the θ2 side. Is
Since the inclination angles θ and θ2 are different, the center line M of the funnel A is
You will hit at a point off.

Considering this from the large flow of the developer t itself, the movement of the developer t on the slope 9 side and the movement of the developer t on the slope 9'side are at positions deviated from the center line M of the funnel A. Join.

Therefore, the developer t discharged from the hopper
The powder pressure in the mounting portion 4, which is the center of the narrowed funnel A, which is most likely to receive the powder pressure can be reduced, and the funnel of the developer is less likely to be blocked.

The developer pouring portion 2 is attached to the attachment portion 4 of the conical portion 8 of the developer discharge receiving portion 1 so as to be parallel to the center line M of the funnel A. As a method of connecting the developer pouring portion 2 and the developer discharge receiving portion 1, for example, an arc welding method is adopted, but the connecting method is not particularly limited.

In this embodiment, the developer pouring portion 2 and the developer discharge receiving portion 1 are joined to form the funnel A. However, if the funnel design restricts the length of the funnel, stainless steel is used. It is also possible to directly carve out a metal such as to produce the funnel.

Developer inflow portion 2 and developer discharge receiving portion 1
After joining, the joint part inside the funnel A is ground particularly at the center. The inner surface of the polished funnel A may be subjected to Teflon treatment, silicon treatment, or wax treatment. By this treatment, the frictional resistance between the developer particles and the treated surface is lowered, and therefore, the funnel clogging of the developer is further difficult to occur.

Next, a method of filling the developer t using the developer filling funnel A according to this embodiment will be described.

As shown in FIG. 58, the freshly manufactured developer t is supplied from the hopper supply port 100 to the developer hopper 1
It is transported to 10 and stored.

The developer t temporarily stored in the developer hopper 110 is discharged from the developer hopper 110 by the rotation of the auger 130 provided in the auger casing 120 provided at the lower part of the hopper 110. By controlling the screw rotation speed of the auger 130,
The discharge speed of the developer t can be easily regulated.

The developer t discharged from the auger 130
Passes through the developer filling funnel A and is filled in the developer supply container X from the filling port 50.

Thus, when the developer filling funnel A according to the present embodiment is used, the powder pressure of the developer t discharged from the developer hopper 110 is relieved and the fluidity of the developer t is reduced. It became good and it became difficult for the funnel clogging to occur.

Therefore, the discharging speed of the developer t from the developer hopper 110 can be increased to such an extent that the developer t is not blocked by the funnel, and the filling cost can be greatly reduced.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

As shown in FIGS. 59 and 60, the developer filling funnel B according to this embodiment has a developer discharge receiving portion 11
And the developer pouring portion 13 attached to the position of the attaching portion 14.

The developer discharge receiving portion 11 and the developer pouring portion 13 are made of a metal having abrasion resistance and rust prevention, such as stainless steel, as in the first embodiment.

The developer discharge receiving portion 11 is formed in a shape in which the cylindrical portion 11 and the conical portion 12 are combined as in the first embodiment, and has the vertical surface 10. Therefore, the inclination angle θ3 of the vertical surface 10 is 90 °.

On the other hand, the inclination angle θ4 of the conical portion 12 is 45 ° or more and less than 90, and more preferably 60 ° or more and less than 90 °.

By the way, as shown in FIG. 59, how the developer particles t ′ move after hitting the slope 10 on the θ3 side and θ4.
The way the developer particles t ″ move after hitting the side slope 12 is different from the center line M of the funnel A because the inclination angles θ3 and θ4 are different.

Considering this from the large flow of the developer t itself, the movement of the developer t on the slope 10 side and the movement of the developer t on the slope 12 side join at a position deviated from the center line M of the funnel A. Particularly, in the case of the developer filling funnel B according to the present embodiment, since the inclination angle θ3 is 90 °, the developer t on the vertical surface 10 side is extruded straight downward from the developer hopper and moves downward. The speed of movement of the slope 12
It is faster than that of the developer t on the side. For this reason, it is possible to deviate from the center line M without concentrating the point where the developer t on the slope 12 side merges into one point.

Therefore, the developer t discharged from the hopper
It is possible to reduce the powder pressure in the mounting portion 4 which is the center of the narrowed funnel A, which is most likely to receive the powder pressure, and it is difficult for the developer to close the t funnel.

The thickness of the developer pouring portion 13 is set as thin as possible, and the shape thereof is a cylinder designed to be as close as possible to the outer diameter of the filling port of the developer supply container X as in the first embodiment. Shaped. Then, the developer pouring portion 13 is attached to the attachment portion 14 of the conical portion 12 of the developer discharge receiving portion 11 in a manner similar to that of the first embodiment so as to be parallel to the center line M of the funnel A. .

The funnel B for filling the developer according to this embodiment.
Can be made by directly carving out metal. Alternatively, the bonding surface may be polished as the center, and the inner surface may be subjected to the same surface treatment as that of the first embodiment.

Thus, when the developer filling funnel B according to the present embodiment is used, the powder pressure of the developer t discharged from the developer hopper is alleviated by providing the vertical surface 10 in particular. Since the fluidity of the developer t was improved, the funnel of the developer t was less likely to be blocked.

Therefore, the discharge speed of the developer t from the developer hopper can be increased to the extent that the developer t is not blocked by the funnel, and the filling cost can be greatly reduced.

<Third Embodiment> Next, a third embodiment of the present invention will be described.

As shown in FIG. 61, the developer filling funnel C of this embodiment has a developer discharge receiving portion 21 and a mounting portion 24.
And the developer pouring portion 23 attached at the position.

The developer discharge receiving portion 21 and the developer pouring portion 23 are made of a metal such as stainless steel having abrasion resistance and rustproofness as in the first embodiment.

The developer discharge receiving portion 21 is a quadrangular prism portion 2
1 and the pyramid portion 22 are combined, and vertical walls 25 and 26 are provided. Therefore, the inclination angle θ5 of the joint surface 20 of the vertical walls 25 and 26 is 90 °.

On the other hand, the inclination angle θ4 of the quadrangular pyramid portion 22 is 45 °.
It is at least 90 and more preferably at least 60 ° and less than 90 °.

As a result, the shape of the funnel C is such that the developer pouring portion 23 has the vertical walls 25 and 2 as shown in FIG.
The shape is completely offset to the 6 side.

By the way, as shown in FIG. 61, the movement of the developer particles t ′ after hitting the slopes 25 and 26 on the θ5 side and the developer particles t ″ after hitting the slopes 27 and 28 on the θ6 side. Since the inclination angles .theta.5 and .theta.6 are different, the movement of the vehicle will hit at a point deviated from the center line L of the funnel C.

Considering this from the large flow of the developer t itself, the movement of the developer t on the side of the vertical walls 25 and 26 and the movement of the developer t on the slopes 27 and 28 deviate from the center line L of the funnel C. Join at the point where Particularly, in the case of the developer filling funnel C according to the present embodiment, since the inclination angle θ5 is 90 °, the developer t on the vertical walls 25 and 26 side is extruded straight downward from the developer hopper to the lower side. And the moving speed thereof is faster than that of the developer t on the slopes 27 and 28 side.

Therefore, the center line L can be further adjusted without concentrating the points where the developer t on the slopes 27 and 28 merges at one point.
It is possible to shift further.

Therefore, the developer t discharged from the hopper
It is possible to further reduce the powder pressure in the mounting portion 24 which is the central portion of the narrowed funnel A, which is most likely to be subjected to the powder pressure, so that the funnel is less likely to be blocked.

The thickness of the developer pouring portion 23 is set as thin as possible, and the shape thereof is designed to be as close as possible to the outer diameter of the filling port of the developer supply container X as in the first embodiment. It has a cylindrical shape.

The developer pouring portion 23 is attached to the attachment portion 24 of the quadrangular pyramid portion 22 of the developer discharge receiving portion 21 so as to be parallel to the center line M of the funnel C by the same connection method as in the first embodiment. Has been.

Incidentally, the developer filling funnel C according to the present embodiment.
Can be produced by directly carving out metal as in the first embodiment. Alternatively, the bonding surface may be polished as the center, and the inner surface may be subjected to the same surface treatment as that of the first embodiment.

When the developer filling funnel C according to this embodiment is used, the powder pressure of the developer t discharged from the developer hopper is relaxed as much as possible by providing a vertical surface. Therefore, it is possible to improve the fluidity of the developer t and make it difficult for the funnel to be closed.

As a result of the above, the discharge speed of the developer t from the developer hopper can be increased to such an extent that the developer t is not blocked by the funnel, and the filling cost can be greatly reduced.

<Fourth Embodiment> Next, a fourth embodiment of the present invention will be described.

As shown in FIG. 63, the developer filling funnel D according to this embodiment has a curved surface 32 on the slope 12 of the second embodiment.
It is made of the same material and shape as those of the second embodiment except that

Due to the curved surface 32, the confluence of the developer t ″ on the curved surface 32 side and the developer t ′ on the vertical surface 30 side is not concentrated at one point, but is further dispersed by the curved surface property of the curved surface 32. , The powder pressure of the developer t discharged from the hopper can be maximally reduced at the mounting portion 34 which is the center of the narrowed funnel D, which is most likely to receive the powder pressure of the developer t. It can be hard to wake up.

Therefore, the discharging speed of the developer t from the developer hopper can be increased to the extent that the developer t is not blocked by the funnel, and the filling cost can be greatly reduced.

<Comparative Example> Next, a comparative example with the present invention will be described.

As shown in FIG. 64, the developer discharge receiving portion 4
0 and the developer pouring portion 43 attached at the position of the attaching portion 44, the developer filling funnel E was produced.

The developer pouring portion 43 is attached so that its center line coincides with the center line M of the funnel E.

When the funnel D according to the present comparative example and the developer filling funnels A, B and C according to the present invention are used and the developer t having the same physical properties is filled in the developer supply container X, the funnel clogging is prevented. In the case where the discharge speed of the developer t from the developer hopper is increased to the maximum extent that does not occur, and when the developer filling funnels A, B, C according to the present invention are used, the comparative example It was possible to speed up the developer discharge speed by a factor of about 2 or more when using the developer filling funnel E.

The reason is that the developer t in the developer-filling funnel E of the comparative example merges together at the conical portion 42 having a symmetrical shape along the center line M of the funnel E toward the mounting portion 44. This causes the powder pressure of the developer t discharged from the developer hopper to concentrate on the mounting portion 44 which is the central portion of the narrowed funnel E,
The developer t temporarily accumulates, and as a result, the developer t blocks the developer filling funnel E.

Therefore, when the developer filling funnel E according to the comparative example is used, the filling cost is significantly increased as compared with the case where the developer filling funnels A, B and C according to the present invention are used. Oops. [Eighth Invention] An embodiment of the eighth invention will be described below with reference to the accompanying drawings.

<First Embodiment> FIG. 65 shows the first embodiment of the method of the present invention.
It is a block diagram of the developer filling device for implementing an Example.

In FIG. 65, 2 is a pallet made of polyacetal resin, which is a vibration generator 3
Supported by. The developer supply container 1 is accommodated in the pallet 2 in an inclined state as shown in the drawing, and the inclination angle θ of the developer supply container 1 with respect to the vertical direction is 5 °.
Is set to.

The pallet 2 is an electromagnetic vibration generator 3
Has a role of transmitting the vibration from the developer container 1 to the developer supply container 1, and it is important that it is lightweight and does not damp the vibration as much as possible. Since the bottom surface 2a of the pallet 2 is inclined as shown in the figure, the developer supply container 1 accommodated in the pallet 2 is held in a state inclined by a predetermined angle θ (= 5 °). The inclination angle θ of the developer supply container 1 with respect to the vertical direction is preferably as large as possible within the range where the toner t does not scatter from the filling port of the developer supply container 1, and the value is 0 ° or more. It is preferably 30 ° or less, and more preferably 5 ° or more and 15 ° or less if possible.

Further, the vibration generator 3 is preferably of an electromagnetic type or an eccentric motor type so that a sufficient vibration can be precisely controlled and transmitted to the pallet 2 placed thereon (in this embodiment, it is preferable). , Using the electromagnetic type). The vibration generated by the vibration generator 3 is basically a longitudinal vibration, and its amplitude and frequency can be freely controlled, depending on various conditions such as the properties of the toner used, the filling amount, and the configuration of the developer supply container 1. The optimum vibration condition is selected.

Thus, according to this embodiment, since the developer supply container 1 is tilted and vibration is applied thereto, the area of the powder surface of the toner t that is primarily filled in the developer supply container 1 is Expands. That is, the powder surface S1 of the toner t in the upright developer supply container 1 shown in FIG. 66 (a) and the powder surface S1 of the toner t in the inclined developer supply container 1 according to the present invention shown in FIG. 66 (b). The relationship of S2> S1 is established between S2. For this reason, the air that is replaced with the toner t filled in the developer supply container 1 escapes better, and the reduction of the powder surface of the toner t in the container 1 is promoted.

Further, lateral vibration including self-excited vibration of the developer supply container 1 is generated at the time of vibrating, and the lateral vibration vibrates the toner t.
The close packing is performed, and the reduction of the powder surface of the toner t in the container 1 is promoted. For that purpose, it is desirable that there is a play between the container 1 and the pallet 2 so that the lateral vibration of the container 1 is easily generated.

Actually, the volume average particle diameter of 8 μm is 100
Developer supply container (volume: 250 cm)
³ , height: 200 mm) is placed on the vibrating device of this embodiment, and a vibration with a longitudinal amplitude of 0.4 mm and a frequency of 50 Hz is set to 1
When applied for a minute, appropriate lateral vibration including self-excited vibration is applied, and as shown in FIG. 67, the powder surface a (10 mm below the filling port) of the toner in the container after the primary filling is b (80 mm below the filling port).
Went down. As a result, it became possible to fill the remaining 40 g of the total filling amount by the secondary filling.

<Second Embodiment> This embodiment is the same as the first embodiment except that the angle θ of the container body with respect to the vertical direction is maintained at 30 °.

When a filling test was actually carried out in the same manner as in Example 1, some scattering of the toner primarily filled from the filling port was observed.

Therefore, when the longitudinal amplitude is reduced to 0.2 mm, the toner scattering from the filling port is no longer seen, and the toner powder surface a (in the container after the primary filling is carried out in the same time as in the first embodiment. 10 mm below the filling port) dropped to b (80 mm below the filling port). As a result, as in the first example, 40 g could be filled by the secondary filling.

<Comparative Example 1> FIG. 68 shows a state showing the structure of the present comparative example.

In this comparative example, as shown in FIG. 68, the bottom portion of the pallet for receiving the developer supply container is horizontal,
The procedure is the same as in the first embodiment except that the container body is held upright.

When a filling test was conducted in the same manner as in the practical example, the powder surface a (10 mm below the filling port) of the toner in the container after the primary filling did not fall to c (60 mm below the filling port) in 1 minute. (See FIG. 3).

Level of the first embodiment (80 mm below the filling port)
When the vibration time was extended to lower the temperature, the time required was about 1.5 times longer than that in the first embodiment, resulting in a significant tuck down.

Further, in order to lower the powder surface within the same time, the longitudinal amplitude of the vibration condition was increased to 0.6 mm, and the toner primarily filled from the filling port was scattered, and it became difficult to control the filling amount. At the same time, the filling line was soiled.

Comparative Example 2 In this comparative example, the first example is used except that the angle θ of the container body with respect to the vertical direction is maintained at 40 °.
Same as the embodiment.

Similar to the first embodiment, when a filling test was actually carried out, a large amount of toner was scattered from the filling port of the container, and the scattering of toner could not be prevented even if the longitudinal amplitude was reduced to 0.2 mm. When the amount of toner for primary filling was reduced to 90 g, the amount of secondary filling was increased to 50 g, and it was impossible to fill unless the filling time was extremely lengthened. [Ninth Invention] An embodiment of the ninth invention will be described below with reference to the accompanying drawings.

<First Embodiment> FIG. 69 is a sectional view of a developer filling device according to the present embodiment, and FIG. 70 is a plan view of the same.

In the figure, reference numeral 5 is a disk-shaped vibrating table, in the center of which a rotary shaft 7 which stands upright is penetrated. The rotary shaft 7 is rotationally driven by the rotary drive device 6, and a plurality of arms 9 are radially attached to a portion of the rotary shaft 7 projecting above the vibration table 5, and each arm 9 has a tip end portion. A pallet 2 is attached so as to be rotatable around a shaft 10. In this embodiment, 16 pallets 2 made of Teflon resin are used, and a developer (hereinafter referred to as toner) is used for each pallet 2.
The developer supply container 1 in which t is primarily filled is accommodated and held.

An eccentric motor type vibration generator 3 is attached to the lower portion of the vibration table 5.

Thus, the developer supply container 1 is primarily filled with the toner t before the container 1 is held by the pallet 2 of the developer filling device. Then, the developer supply container 1 in which the primary filling of the toner t is completed is sequentially placed on each pallet 2 of the developer filling device, and is vibrated by the vibration generating device 3.

When the containers 1 are installed on all of the pallets 2 on the vibration table 5, the rotation driving device 6 is driven to rotate the pallets 2 at high speed. The high speed rotation state of the container 1 is shown in FIG.

Then, the toner t in each developer supply container 1 is subjected to the centrifugal force in addition to the vibration by the vibration generator 3, and the sedimentation in the container 1 after the primary filling is promoted. The volume for the secondary filling in the container 1 increases. In order to prevent the toner t from scattering from the filling port of each container 1 and to effectively use the centrifugal force to reduce the powder surface of the toner t in the container 1, the filling port of the container 1 is rotated orbital of the container 1. It is desirable to face the inside.

After that, the container 1 is rotated together with the pallet 2 for a certain period of time, the rotation is stopped, the container 1 is taken out from the pallet 2, and the taken-out container 1 is secondarily filled with the toner t. At this time, the powder surface of the toner t in the container 1 is lowered by the vibration and the centrifugal force as described above.
Since the volume for the next filling is increased, more toner t can be efficiently filled in the container 1 in a short time.

By the way, the pallet 2 has a role of transmitting the vibration from the vibration generator 3 to the held container 1, and it is important that the pallet 2 is lightweight and does not damp the vibration as much as possible. The number of pallets 2 can be arbitrarily set depending on the filling tact, vibration, and scale of the rotary drive device 6.

Further, the vibration generator 3 is preferably of an electromagnetic type or an eccentric motor type so that a sufficient vibration can be precisely controlled and transmitted to the pallet 3 placed thereon (in this embodiment, it is preferable). , Using an eccentric motor type). The vibration generated by the vibration generator 3 is basically longitudinal vibration, and its amplitude and frequency can be freely controlled,
The optimum vibration condition is selected according to various conditions such as the properties of the toner t used, the filling amount, and the configuration of the developer supply container 1.

Regarding the rotation condition of the container 1, it is better to let the toner t in the container 1 settle in a shorter time. Therefore, the rotation speed and the turning radius are increased, and the settling condition of the toner 1 in the container 1 is increased. The rotation time may be set in accordance with the above, but at that time, it is necessary to consider the property of the toner t to be used so that the toner t in the container 1 is not fused and solidified.

Actually, one toner having a volume average particle diameter of 8 μm is used.
A developer supply container (capacity: 250
cm ^3, height: a 200 mm) placed on a filling device of the present embodiment, the vertical amplitude: 0.4 mm, frequency: After applying a vibration of 50 Hz, the rotational speed: 600 rpm, rotation time: under conditions of 1 minute Rotated.

As a result, as shown in FIG. 72, the toner powder surface a (10 mm below the filling port) of the toner in the container after the primary filling is b.
(80 mm below the filling port), it became possible to fill the remaining 40 g of the total filling amount by the secondary filling.

<Second Embodiment> This embodiment is the same as the first embodiment except that the rotation condition of the container is set to a rotation speed of 800 rpm and 45 seconds.

When a filling test was carried out in the same manner as in the first embodiment, almost the same effect as in the first embodiment was obtained.

<Comparative Example> In this comparative example, as shown in FIG. 73, the developer supply container 1 was vibrated in the upright state. In this comparative example, the electromagnetic vibration generator 8 was used,
The vibration conditions are the same as in the first embodiment.

When a filling test was conducted in the same manner as in Example, the powder surface a (10 mm below the filling port) of the toner t in the container 1 after the primary filling was c (60 m below the filling port) within the same time.
m) did not go down (see FIG. 72).

When the vibrating time was extended to lower the powder surface of the toner t to the level of the first embodiment (80 mm below the filling port), the vibrating time took about twice as long as that of the first embodiment. I was down.

In order to lower the powder surface within the same time,
When the vertical amplitude of the vibration condition was increased to 0.6 mm, the primary filling toner t scattered from the filling port, making it difficult to control the filling amount, and at the same time soiling the filling line.

As is apparent from the above description, according to the first invention, not only the vibration applied to the developer supply container is hardly damped, but also the self-excited vibration of the container is added.
It is possible to secure a predetermined amount of the developer to be filled secondly or thirdly. This makes it possible to fill the developer with higher density, reduce the number of developer supply containers used, and further reduce waste. Further, the copy cost per sheet can be reduced, and the vibration can be effectively transmitted to the developer supply container, so that the conventional vibration time can be greatly shortened and the filling cost can be reduced.

According to the second invention, in addition to the effect obtained by the first invention, the effect that the developer supply container is hardly scratched by the action of the protective layer formed on the vibrating frame is obtained. In this case, if the thickness of the protective layer is 1 mm or less, the vibration from the vibration device is transmitted to the developer supply container as it is without being damped by the vibration frame.

According to the third invention, in addition to the effect obtained by the first invention, the vibration amplification effect of the metal spring allows
In particular, when a large number of large-capacity developer supply containers are filled with the developer at one time, or when the vibration generator has a small capacity, it is possible to efficiently fill the developer with a high density.

According to the fourth invention, since the gap is provided between the carrier pallet and the developer supply container after the primary filling of the developer, the self-excited vibration of the developer supply container is promoted and the carrier pallet is used. This not only compensates for the attenuation of the vibration amplitude, but also increases the vibration amplitude, so that it is possible to increase the filling amount of the developer that is secondarily or thirdly filled, and it is possible to significantly reduce the vibration time. Also, the filling cost can be reduced. According to the fourth invention,
Since there is no gap between the transport pallet and the developer supply container before the primary filling, the filling port of the developer supply container is securely fixed to the discharge port of the developer filling device during the primary filling. It is possible to perform the filling, and it is possible to prevent the developer from being scattered around during the filling.

According to the fifth invention, since the protective layer is formed on the surface of the carrier pallet which holds the developer supply container, the fourth embodiment is provided.
In addition to the effect obtained by the invention, the effect that the holding surface of the developer supply container is not easily scratched is obtained.

According to the sixth aspect of the present invention, the frictional resistance between the funnel and the developer is reduced by the surface treatment of the inner surface of the developer-filling funnel, so that the developer funnel is less likely to be clogged and the developer discharging speed is reduced. Can be increased to reduce the filling cost.

According to the seventh aspect of the present invention, by changing the shape of the funnel, the powder pressure at the portion where the developer is likely to cause the funnel clogging can be alleviated as much as possible, thereby improving the fluidity of the developer. It is possible to prevent the developer from closing the funnel, increase the developer discharging speed, and reduce the filling cost.

According to the eighth aspect of the invention, vibration is applied to the developer supply container in a tilted state, so that the powder surface of the developer primarily filled in the container is promoted to decrease, and the developer level is increased. Dense packing can be done efficiently in a short time.

According to the ninth invention, when the developer supply container in which the developer is primarily filled is vibrated, for example, the container is rotated at a high speed and a centrifugal force is applied thereto, so that the developer supply container The reduction of the powder surface of the primarily filled developer is promoted, and the dense packing of the developer is efficiently performed in a short time.
