Below to the technology of the present invention further instruction in addition.

But the containe for supply ink powder that the recycle that the present invention relates to is used is the new design of the inventor, in prior art, do not have fully, be necessary to specialize, so that understand, above-mentioned design is meant and can makes vessel separate the mechanism that makes up with the part of installing wherein.

Owing to adopt this mechanism, the part that revolving member is such is installed in the vessel earlier, behind the assembling containe for supply ink powder, toward container filling ink powder, it is positioned on the image processing system with usual method, be concatenated to form image, the electrical condenser that ink powder is used up is not as waste treatment, but separation container body and part, removes after the dirts such as ink powder that adhere on the vessel of above-mentioned separation and part, combination once more can be for re-using.

Containe for supply ink powder of the present invention is also taked all measures certainly except above-mentioned said detachable vessel body and part, even so that re-use after the recombinant, ink powder can not take place yet leak, and can keep desired powdered ink feed performance.

About for outside the characteristic that reaches the object of the invention,, the containe for supply ink powder summary is described earlier owing to can use the common key element that containe for supply ink powder had.

With regard to vessel, its shape size is different because of the image processing system kind, for example, is that the two ends fixed size of 15-30cm left and right sides housing section is 25～70cm in length mostly as vessel ²Side plate.

Vessel has ink powder holding part and cover separable and inseparablely be one-piece type branch, though there is the metal of use to make on the material, injecting resin moulding making mostly usually.

In addition, vessel is provided with two maintaining parts, two top ends of rotary middle spindle are to be combined in the above-mentioned maintaining part with freely rotating, and at least one maintaining part is a through hole, and generally the leading section of the rotary middle spindle that is supported at this through hole is connected with the drive source of image forming device body.

On the other hand, many revolving members are provided with rotary middle spindle at both ends at least, have at central portion and to make the loose function of sending towards the outside of filling ink powder, the leading section of rotary middle spindle one end is connected with the drive source of image forming device body by the such power transmission members of the gear that is fixed on this, becomes to drive the rotating mechanism of revolving member.

The concrete shape of revolving member central portion etc. is various, according to central portion mechanism this revolving member is divided into agitating type in the present invention and the supply roll shape describes.

If lift the agitating type example, the type of ladder shape shown in the label 2 among Fig. 2 is then arranged, be provided with the screw type (being also referred to as spiral) of spiral blade, the coiled type type reaches member wiry etc. only is set, mainly be to make the ink powder appropriateness of taking in loose, be transplanted on the toner replenishing port of container, must be effectively carry out supply to the development section of image processing system by revolving member revolution, therefore, try every possible means to improve physical strength for the material that constitutes central portion, shape etc.

The supply roll shape have the surface have magnetic by magnetic attraction sticking magnetic ink powder so-called magnet roller and be located at the pattern that keeps non-magnetic toner in the concavity notch on surface, usually be arranged near the slot-shaped toner replenishing port of vessel, make the revolution of supply roller, fall the ink powder that is kept, this ink powder replenishes to development section by toner replenishing port.

When using the magnet roller, the ink powder that passes through the terminal surface in contact that disposed scrapes plate (being called scraper plate), makes to remain on ink powder and fall.

Be installed in revolving member kind on the vessel and quantity and do not do special restriction, but most occasion adopts and only establishes a stirrer or stirrer is set and each one on supply roller.

Say the practice of past vessel filling ink powder again,, thought various ways at aspects such as its shapes about a bit.For example, carrying out in the ink powder filling method, ink powder filling orifice and pressurized air bleed hole are being set on vessel with pressurized air attraction method, from pressurized air bleed hole emit pressurized air on one side, the ink powder filling injected from filling orifice on one side.Behind the filling ink powder, above-mentioned hole is stopped up with bolt.

Below, the characteristic of powdered ink feed device of the present invention once is described.

Containe for supply ink powder of the present invention be basically the rotary middle spindle of revolving member by being located at the through hole that covers on the member, and be mounted with detachable lid member on the opening of vessel being located at.So-called among the present invention " opening and closing the lid member of opening " is meant " as chimeric then closing any opening, as pulling down the detachable lid member of then opening the opening ".

First function that the lid member that has bearing that is used on the containe for supply ink powder of the present invention is required is can open and close opening at an easy rate and will be contained on the opening with duration of work the ink powder leakage not to take place between the storage life of back, and also identical after the recycle use.When being the filling ink powder, the big problem that the ink powder leakage causes to realize highly dense useless filling because of ink powder leaks, in addition if formation brings bad influence to image in image processing system inside from leaking between lid member and opening that then ink powder can be made dirty, if leaking then from the lid through hole of member and centre of gyration between centers, ink powder enters bearing portion etc., the result, the misalignment of rotary middle spindle, be difficult to guarantee the vertical precision of bearing, revolving member can not precision rotating, powdered ink feed is brought hinder.

Second function that the lid member is required is the bearing function for the rotary middle spindle of revolving member, guarantee the vertical precision of bearing for the axle of bearing and turning central shaft, wish that the portion of bearing at least of covering member has the physical strength that few generation is distorted, in addition, it is concentric with rotary middle spindle to wish to cover the through hole of member.

In the present invention, there is use to have the occasion of the lid member of above-mentioned two functions simultaneously, following this occasion is also arranged: for more effective performance two sides' function, except the lid member, also prepare other all-in-one-piece bearing components, on the lid member, mainly have above-mentioned first function, on bearing components, mainly have above-mentioned second function.Therefore, the what is called of using in the present invention " the lid member that has bearing " is meant member (pattern A) that covers member itself and have the bearing function or the member of being made up of lid member and other all-in-one-piece bearing components (pattern B).

But,,, we can say and use pattern B more than using pattern A ideal so use two aspects to consider from containe for supply ink powder performance and recycle owing to cooperate various functions can select material, size, shape, thickness etc.

Through hole is set on the bearing components, and rotary middle spindle wishes that by above-mentioned through hole above-mentioned through hole and rotary middle spindle are roughly concentric.

Bearing components is identical with above-mentioned bearing portion, preferably have to distort few physical strength takes place, if from others, in order to give full play to the bearing function, preferably has lower flexible and raising wearing quality, for easy open-close lid member and ink powder does not take place leak, preferably have than higher flexible, be the material of good springiness.As the material that is used for two members, select tygon for example or polyacetal to have the material of various physical strengths like that.

Have again,, with regard to the through hole length that contacts with rotary middle spindle, preferably make bearing components side longer at least than covering member for the revolution runout of rotary middle spindle does not take place.Though the through hole length of the bearing components that contacts with rotary middle spindle without limits, about about 1-6mm.

For more certain impermeability that prevents between ink powder leakage and assurance and revolving shaft, preferably use containment member, with lid member adjacency, connect airtight the configuration containment member at least, so very effective.For the sealing effectiveness of better performance containment member, on the lid member, cylindrical wall is set especially, embed containment member at its recess, and then make it become compressive state, more effective like this.About the using method of sealing member, use bearing components in any case, can both be suitable for.Especially attracting method toward container filling ink powder occasion by air, it is very important to improve impermeability.

The sealing member is provided with through hole, is used to pass through rotary middle spindle.As containment member, preferably the high member of impermeability elastic force uses materials such as felt, rubber, resin, also can use two above containment members as required.

The position relation of lid member, bearing components and containment member is not particularly limited, but give full play to the bearing function in order to prevent that ink powder from leaking, be preferably in and cover the member recess and include containment member in, especially preferably from vessel press cover member, containment member, bearing components arranged in order.About the using method of this configuration sequence and member, even do not use bearing components occasion (pattern A) also identical.

Skew ground must not take place respectively and is connecting airtight in lid member, bearing components and containment member vertically on rotary middle spindle, for this reason, be preferably on a certain side of covering member and bearing components or the both sides cylindrical wall is set, form recess, become mutual embedded structure, make it integrated.

To cover member, bearing components and containment member axial dipole field does not take place on rotary middle spindle in order to make, on rotary middle spindle, fixedly install supporting mass with this approximate vertical, on rotary middle spindle, fixed component is set in addition with detachable state, with above-mentioned supporting mass and the above-mentioned lid member of fixed component clamping, bearing components and containment member, be effective like this.Being connected, being fixed on the such power transmission members of gear on the rotary middle spindle with the revolution drive source can double as be the said fixing member also.Even do not use bearing components occasion (pattern A), above-mentioned this clamp method also can be suitable equally.

The most handy resin of supporting mass and the rotary middle spindle be located on the rotary middle spindle are one-body molded, and it is big slightly that its size cans be compared to supporting member most.

Be securely fixed in the revolution of guaranteeing revolving member on the vessel in order to cover member (pattern A) or lid member and bearing components (pattern B); along opening edge or from opening edge one at interval arranged outside cylindrical wall is arranged; when the lid member occasion (pattern A) of using the double as bearing; this lid member can be contained on the above-mentioned cylindrical wall; cover member and bearing components occasion (pattern B) when using, lid member, bearing components can be installed in respectively on opening, the cylindrical wall.This cylindrical wall length is not particularly limited, and is located at the cylindrical wall occasion of opening edge, is below 1/2 of opening footpath even grow the longest, is located at the cylindrical wall occasion of covering member or bearing components, then is below 1/3 of opening footpath.

No matter be pattern A or pattern B, can between lid member or bearing components and above-mentioned cylindrical wall, screw mechanism or hook mechanism be set, form more firm stationary state.For example, being provided with at least one side of covering member and bearing components is to close pawl, in the cylindrical wall that is formed at opening the pawl fixed part is set, perhaps opposite, also can the pawl fixed part be set a side of lid member and bearing components, be to close pawl the cylindrical wall setting that is formed at opening, as hook mechanism.So-called pawl fixed part is meant the structure in projection, recess or hole and so on.Can use as pawl being located at a part of otch that covers the cylindrical wall on member or the bearing components or be located at the flange on this cylindrical wall.

Opening, lid member, bearing components, the various cylindrical wall and the supporting mass shape that are located on the above-mentioned member are not particularly limited, and still, install and recycle operation consideration from revolving member, and be preferably roughly rounded, mutual coaxial setting.Though size also is provided with qualification,, for example with opening, the most about 3cm degree of diameter.The lid member is owing to must be securely fixed on the opening, so preferably use resilient material, ratio open is big slightly.Be located at the through hole that covers on member, bearing components and the containment member respectively the rotary middle spindle that passes it turned round sleekly, and rotary middle spindle preferably with through-hole wall exposure level thickness.

About lid member and bearing components, except roughly rounded plate object, can use the member of forming by Embedded Division and flange part, it is selected to press physical strength according to desired function, though material is not limited, preferably uses resin.

Constitute in two rotary middle spindles of revolving member, at least the rotary middle spindle that is connected with drive source can use be located in the container in the past with the incorporate parts of revolving member central portion, but from installing and the recycle operation is considered, then with newly figure out, can want to middle body from, install and remove freely mechanism for well.Though the length to the rotary middle spindle of these separable mounting or dismounting does not limit, about the about 5cm of length.

Though as revolving member can use above-mentioned in the past agitating type and all members of supply roll shape, also can use member in order to realize that the object of the invention is newly figured out.For example, remembering the parts that use in first example, flat member is installed down outside the ladder shape stirrer.This revolving member enlarges installing under the flat member state, and it is big to become the ratio open footpath, but because flat member has the property of putting forward, while if turn round and push, revolving member can be easily and correctly from shedding motion on vessel.

Use this agitating type revolving member that has flat member, it is turned round in container, the ink powder that flat member connects nearly container inner wall face can both scrape, the ink powder consumption efficiency is good, the result, the amount of toner that remains in institute's use container can reduce, thereby can alleviate the clean-out operation that uses for recycle, do not hinder fully in view of installing yet, so be to be used for the very effective method that recycle is used, compare with using not the agitating type revolving member of strap shape member, can obtain extraordinary effect.

In the present invention, shown in first example, near the opposite other end of the centre of gyration shaft end of member is covered in configuration, and with rotary middle spindle axially roughly be fixed with tabular ways in vertical direction, can make revolving member correctly and easily be installed in institute's allocation in the vessel by this ways by opening.This ways is the shape or the size of slipping with at least a portion of vessel inner peripheral surface, and is so very effective, even run into the member of the shape or the size of opening, as long as how much have pliability, also can be suitable for.As shape, can use circular or fan-shaped etc.

Assembling about containe for supply ink powder of the present invention, be not particularly limited, use recycle part occasion too, but, its elemental operation method is that such use one of can be got in " the lid member that has bearing " of various forms as mentioned above, one side that will constitute two rotary middle spindles of revolving member usually passes and is located at after the through hole that covers on the member, insert the opposing party's of rotary middle spindle leading section toward the inboard from the opening that is located at vessel, be set to institute's allocation, to cover member then and embed opening, be fixed.

The occasion (pattern B) of the member conduct " the lid member that has bearing " that use is made up of lid member and other all-in-one-piece bearing components, or use containment member occasion, must use rotary middle spindle keeping by through hole, so that on rotary middle spindle, make these members axially be in tightlock status, when especially these members have mutual composite construction, make them be combined into high tightlock status.When being located at supporting mass on the rotary middle spindle and freely these members of fixed component clamping of mounting or dismounting too.

Constitute be provided with in two rotary middle spindles of revolving member cover member one side do not use can with revolving member central portion separated structures, with tightlock status plural member as described above is installed on this rotary middle spindle earlier, afterwards, it is combined with the revolving member central portion, with the opening of lid member embedding vessel, see very desirable from the operation aspect.

As mentioned above, when using the agitating type revolving member occasion that pliability sheet member is installed at central portion, must be inboard while the revolving member revolution is inserted from the opening that is located at vessel, like this, flat member is curling shape at the revolving member central portion, can insert revolving member sleekly from opening.

Have again, as mentioned above, ways is set on revolving member, toward the inboard revolving member that inserts, at least a portion of this ways and vessel inner peripheral surface is slipped, revolving member more correctly can be installed in the institute's allocation in the vessel from opening.It is especially effective that this guide plate and central portion are equipped with the words that pliability sheet member share.

The operation that the lid member is embedded opening is undertaken by pressurization, and preferably this pressure is about 1-10kg.
