Embodiment
Below, describe the toner accepting container among the present invention and the embodiment of toner supply device in detail with reference to the accompanying drawings, but the present invention is not limited to this embodiment.
At first, Fig. 1 is with the vertical disconnected front view (FV) as the simple expression of unitary construction of the plain paper copier of image processing system, substantial middle portion in the body case 2 of plain paper copier 1 is provided with the photoreceptor 3 of drum type, dispose charged exposure device 4, developing apparatus 5, reproducer unit 6, separation vessel 7, cleaning device 8 etc. around this photoreceptor 3, the top of photoreceptor 3 disposes fixing device 9.Developing apparatus 5 is made of imagescope 10 and toner supply device 11.
And then, in toner supply device 11, the toner accepting container holding member 12 of cylindric form is fixed on the imagescope 10.This toner accepting container holding member 12 is inserted into, thereby makes the toner accepting container 13 of the cylindric form of accommodating toner roughly be level and can rotate freely.Use following figure to illustrate.
Fig. 2 is the outside drawing of toner accepting container 13.Fig. 3 represents the outside drawing of the shape after the cap with the toner replenishing oral area of toner accepting container 13 unloads, Fig. 4 represents the sectional drawing of the shape after the cap with the toner replenishing oral area of toner accepting container unloads, Fig. 5 is the amplification profile diagram of the part of toner accepting container 13, and Fig. 6 is the sectional drawing of toner supply device 11.
At first, described toner accepting container 13, make a distolateral undergauge of vessel 15 cylindraceous, form toner replenishing oral area 16 on the leading section of this reducing diameter part 15a, had the spiral groove 17 that on the inner peripheral surface of cylindric form, is convex and is concavity on the outer peripheral face on the vessel 15.Seal with rear cap 24 on the rear portion of vessel 15 cylindraceous.
Promptly, toner accepting container 13 is near the escape hole of vessel 15 cylindraceous, towards escape hole, has the shape of the reducing diameter part 15a that diameter reduces gradually with respect to the long axis direction of accepting container.The undergauge angle of the reducing diameter part that diameter reduces gradually is preferred, and the outer wall of accepting container is no more than 45 ° angle from being with the direction of principal axis of long axis direction quadrature.
In this vessel 15 cylindraceous, on the reducing diameter part 15a of toner replenishing oral area side, the interval of spiral groove 17 is narrowed down and form.In imagescope during the supply toner, toner accepting container 13 rotates around central shaft cylindraceous by rotary driving part described later, be accompanied by the rotation of this toner accepting container 13, spiral groove 17 plays the function that the toner discharging port 35 on the leading section of toner replenishing oral area 16 is transported the flank of toner.Because this moment, spiral groove 17 diminished at interval gradually towards toner replenishing oral area 16, the performance of transporting of toner improves greatly.When even the residual quantity of the toner in the toner accepting container 13 tails off, also can supply with toner to developing apparatus swimmingly.
The ratio L/D of drum diameter D and the long L of cylinder is during less than the scope of 1/2≤L/D≤10, the travelling speed of toner will be unusual quickening, and when bigger than the scope of 1/2≤L/D≤10, the travelling speed of toner will be unusual slow down, preferably can obtain the scope of 1/2≤L/D≤10 of suitable toner travelling speed.
In addition, wall thickness of cylinder t is 0.3mm≤t≤5.0mm, wall thickness of cylinder deviation △ t≤20%, for example such shown in Fig. 5 (a), part at wall thickness of cylinder t1 and wall thickness of cylinder t2, its wall thickness poor, be that the wall thickness of cylinder deviation does not satisfy △ t≤20% o'clock, spiral groove 17 will damage, the transporting performance and will reduce of the toner in the toner accepting container 13.
In addition, such shown in for example Fig. 5 (b), the part of wall thickness of cylinder t3 and wall thickness of cylinder t4, poor when its wall thickness, be that the wall thickness of cylinder deviation does not satisfy △ t≤20% o'clock, it is big that spiral groove 17 will become, perhaps can leave toner on the less part of wall thickness, the transporting performance and will reduce of the toner in the toner accepting container 13.
Like this, wall thickness of cylinder t is 0.3mm≤t≤5.0mm, wall thickness of cylinder deviation △ t≤20% o'clock, transporting performance and will improve greatly by the toner in the toner accepting container 13 of spiral groove 17, even the residual quantity of the toner in the toner accepting container 13 becomes more after a little while, also can supply with toner to developing apparatus swimmingly.
The link 22 of the gear set 20 that rotary transmission part 18 is driven by 19 rotations of engine 19, launched machine, the final gear 21 with gear set 20 and the turning axle 33 that is connected with final gear 21 etc. constitutes.
The toner replenishing oral area 16 of toner accepting container 13 is made of cap 27, fold formula inner cap 28, toner discharging port parts 29 etc.
In addition, link 22 is made of turning axle 33 that is connected with final gear 21 etc., if in link 22, insert toner discharging port parts 29 as the outstanding end of toner accepting container 13, fold formula inner cap 28 is slided to toner accepting container base side, fold formula inner cap 28 moves to aperture position, toner discharging port 35 is just opened, toner accepting container 13 is communicated with the installation of toner accepting container 13 by toner discharging port 35 and imagescope 10.
Therefore, when in plain paper copier 1, toner accepting container 13 being installed, as long as the cap 27 with the toner replenishing oral area 16 of toner accepting container 13 takes off in advance, just needn't open fold formula inner cap 28, preventing toner when toner discharging port 35 is scattered, also preventing the pollution of the toner that is scattered operator's hand or clothes.
When in addition, toner accepting container 13 being taken out from toner accepting container holding member 12, because fold formula inner cap 28 can turn back to the original state of remaining silent, when toner discharging port 35 is produced toner and is scattered by toner place that fold formula inner cap 28 covered, adheres to, also prevented the pollution of the toner that is scattered to operator's hand or clothes on the outstanding end that prevents by toner accepting container 13.
The manufacture method of the toner accepting container 13 of this invention is if with molding resin material, then can enumerate following method, for example, the such blow molding of blowing of natural shape base or injection blow molding, injection molding forming, reducing formation is perhaps in the method for utilizing groove in the processing processing of back after the formation of paper tube.Control was processed as the wall thickness of regulation when the wall thickness of toner accepting container 13 was shaped, in addition, make the material preferred polyolefm resinoid of toner accepting container, special preferably polyethylene or polypropylene among the present invention.
As the toner of accommodating in the toner accepting container among the present invention, except common crushed toner, preferably the size-grade distribution of each toner particle and shape compare the polymerization toner of homogeneous.The polymerization toner here is meant toner with the generation of the resin of bonding agent and the shape of toner, be the starting monomer by adhesive resin polymerization with and subsequent the chemical treatment toner that forms, obtain.Be through polyreaction such as outstanding turbid polymerization, emulsion polymerization and according to the toner that operation obtains that melting between the particle that after this polyreaction, carries out of necessity particularly.
Conform to the polymerization toner of accommodating in the toner accepting container of the present invention, just should have special shape.Promptly, as the preferred polymerization toner that is applicable to this invention, shape coefficient is more than the 65 number % at the toner particle within 1.2～1.6 the scope, the coefficient of alteration of shape coefficient is below 16%, in the time of among such toner is used for image processing system, the vibration of the cleaning blade in the image processing system is just very steady.
In addition, as being applicable to the preferred polymeric toner of the toner accepting container of this invention, the coefficient of alteration of the shape coefficient of toner is below 16%, and the number coefficient of alteration in the number size-grade distribution of toner is below 27%.If use this toner, just can improve the spatter property of image processing system, the line reproducibility excellence of the image that obtains can form high-grade image quality for a long time.
In addition, as the preferred polymeric toner that is applicable to the toner accepting container of this invention, making the toner particle that does not have the angle in the toner by control is more than the 50 number %, and the number coefficient of alteration in the number size-grade distribution is 27% when following, just can improve the spatter property of image processing system, the line reproducibility excellence of the image that obtains can form high-grade image quality for a long time.
Be applicable to the shape coefficient of preferred polymeric toner of the toner accepting container of this invention, shown in following formula, represented the circularity of toner particle.

Below, specify the present invention according to drawing, but the present invention not only is defined in this.
Fig. 8 (a) is the stereographic map of the powder accepting container that the present invention relates to, and its peristome is by membranaceous encapsulant sealing, and Fig. 8 (b) expression is in order to the sectional drawing (the AA section of Fig. 8 (a)) of the peristome of supplying with powder.
201 is vessel among the figure, and it is the open rigid body container of at least one end, and it is for carrying out injection molding forming with thermoplastic resin described later or slush molding obtains.202 is preferably similar with body 201 resin of fixed cap.Fixed cap 202 and vessel 201 are one-body molded as the plastic shaping thing together, it seems from cutting down component count, shortening container assembling procedure and the reusable viewpoint of container, and be a kind of desirable method.
203 is lid, is arranged on the open end on the vessel, the preferred employing resin similar with vessel.In addition, preferred container body 201 and lid 203 be one-body molded together, its reason is the same with above-mentioned fixed cap.When the powder accepting container that the present invention relates to has slide lid 205 such in Figure 14 (a) and (b) described later, lid 203 with respect to glide direction about have the teat that is connected with the sliding part of slide lid 205.
The 204th, as the membranaceous encapsulant with peristome 2032 sealings of lid 203 of the seal member that the present invention relates to, can be connected on the lower surface of the side face of peristome 2032 and lid 203 with peeling off.Dispose a plurality of projections that describe in detail later on the lower surface 2032 of lid 203 with systematicness.Encapsulant 204 for example by the method known to bonding agent, heat-sealing, the pressurization etc. usually by bonding, but among the present invention preferably by deposited carry out bonding.Shown in Fig. 8 (a), the front end of membranaceous encapsulant 204 is positioned near the end of peristome 2032, firmly be fixed on the front end fixed part 2321, membranaceous encapsulant 204 can be connected on the lower surface 2033 with peeling off, and extension is folded back near the other end of peristome 2032.Extension with membranaceous encapsulant 204 turns back like this, if carry out peeling off of membranaceous encapsulant under the state that turns back, the glass angle on the lower surface 2033 becomes acute angle, therefore peels off easily.
The material that compacting tygon or polypropylene obtain in the material that material, compacting polypropylene and the polyester that the material of membranaceous encapsulant 204 can adopt mylar, compacting tygon and polyester to obtain obtains, the aluminium foil etc. has pliability and for the material with intensity such as disrumpent feelings, preferred multilayer has the contact face of a side of the layer structure of multiple film material and the described lower surface 2033 that disposes a plurality of projections and is preferably formed by the material of the performance sealing that is known as sealant.
The mode chart of a plurality of projections that 11 (a) (b) dispose on the peristome for the vessel 201 that the present invention relates to of explanation and the contact condition of membranaceous encapsulant 204 is before 11 (a) expression heat-sealing is implemented, after 11 (b) expression heat-sealing is implemented.Before shown in Figure 11 (a), sealing like that, only the projection front end and the membranaceous encapsulant of the configuration of vessel 201 sides contact, but after the heat-sealing of Figure 11 (b), heating when process seals, when a little fusion of projection front end of vessel side and membranaceous encapsulant are deposited, by the fusion of sealant material 2041 on membranaceous encapsulant 204 sides, that does not omit is full of between the projection, thereby has realized sealing.In addition, the membranaceous encapsulant 204 among the present invention has multi-ply construction, but Figure 11 (a) (b) in for simplicity, only represented sealant material layer, constitute layer and omitted other.
Fig. 9 (a) is the stereographic map of the powder accepting container membranaceous encapsulant 204 peeled off from vessel 1, the BB sectional drawing of Fig. 9 (b) expression 9 (a).Figure 10 represent with in the state from the stereographic map of beneath.The a plurality of projections that are provided with on the peristome periphery that the present invention relates to are arranged on the lower surface 2033 of peristome 2032.
Among Fig. 8 (a), if with the peristome of vessel 201 membranaceous encapsulant 204 by the powder accepting container of membranaceous encapsulant 204 sealings, towards the direction traction that is acute angle with respect to the surface of contact between vessel and the membranaceous seal member, the lower surface 2033 of peristome 2032 will be stripped from gradually.As Fig. 9 (a) at membranaceous encapsulant under the state that right-hand quilt is fully pulled out, peristome 2032 becomes open state, the powder T in the vessel 201 will fall for supply.
In the powder accepting container that the present invention relates to, by on the lower surface 2033 of vessel 201, having disposed a plurality of projections, reduced and friction factor, made and carry out peeling off of membranaceous encapsulant swimmingly from the lower surface 2033 and be achieved as the lower surface 2033 of the contact site of membranaceous encapsulant and vessel.
A plurality of projections about the vessel side setting of the powder accepting container that the present invention relates to describe.The a plurality of projections that are provided with on the powder accepting container that the present invention relates to, because its configuration status has systematicness, therefore in the firm effect that is connected of performance and membranaceous encapsulant 204, with membranaceous encapsulant 204 when vessel 201 is peeled off, need not to use bigger strength just can realize peeling off swimmingly.
Among the application, by having invented such powder accepting container that has disposed a plurality of projections in the vessel side, can under condition stably, realize between vessel and the membranaceous encapsulant firm connectivity and fissility swimmingly, therefore be lowered for the load that vessel applied, obtained promoting the reusable effect of powder accepting container.
In addition, in the described prior art, the minimum requirement of surface of contact of vessel 201 and membranaceous encapsulant 204 has the flatness of convex-concave difference less than 10 μ m.If this is poor because form convex-concave on both surface of contact, will form the slit between vessel and the membranaceous encapsulant, the moistures that the powder of accommodating is scattered from this slit or container is outer etc. are the reasons that causes the powder quality low from the slit intrusion.But, among the present invention by between vessel and membranaceous encapsulant, projection being set, both positive formation concavo-convex, can not accommodate the low of powder quality in the container that powder is scattered and the influence of external environment condition causes again.Obviously, it seems that this viewpoint from prior art can't anticipate.
Be provided with a plurality of projections on the vessel side and the contact site membranaceous encapsulant that the present invention relates to, powder just can not take place to be scattered and to accommodate the low reason of the quality of powder and unclear, but infer it to be because the projection that is provided with on the vessel side has certain rules, suppose to have formed the slit on the contact site of vessel and membranaceous encapsulant, powder particle is by packing near the slit, therefore prevented from being scattered and the intrusion of moisture etc. of slit powder, but this supposition is in fact not sure.
As mentioned above, a plurality of projections of being provided with on the vessel of the powder accepting container that the present invention relates to have certain rules, particularly, 1. shape, 2. height, 3. at interval, 4. density and 5. section configuration.Be elaborated with regard to these below.
The a plurality of projections that the present invention relates at first have regularity in shape at it, the projection of mesh-shape configuration in the island shown in Figure 12 (a) for example, 12 (b), but shape is not limited in this.
The height of the projection that the present invention relates to is below the above 300 μ m of 30 μ m, the projection of preferred value below 200 μ m more than the 70 μ m.In addition, the height of projection refers to distance shown in the h among Figure 13 (a).
The projection that the present invention relates to is with the arranged spaced below the 500 μ m more than the 10 μ m, the following interval of the above 300 μ m of preferred 100 μ m.Here the interval of projection is meant the distance between the extreme higher position of the rising height of representing with d among Figure 13 (b)～(d), in addition, refer to distance between the extreme higher position intermediate point of height shown in Figure 23 (d) when being square in the section configuration of projection.
The projection that the present invention relates to has confirmed that its density preferred disposition is 10/mm
2More than 1000/mm
2Below.
Square, triangle shown in preferred Figure 13 of the section configuration of the projection that the present invention relates to (a)～(d), semicircle and trapezoidal.The projection that the present invention relates to is owing to have these section configurations, projected front ends meeting homogeneous is deposited when heat-sealing, even when container is reusable, carry out repeatedly and the easypro shape sealing of film, the heat-sealing of material 204 is even also may keep the strength of joint and the fissility swimmingly when reusing of accommodating the degree that does not hinder circulation of goods as powder.
The above-mentioned projection that is provided with on the vessel that the present invention relates to can be by magnifier qualitatively with its shape of Visual Confirmation and section configuration, can from by the height of the quantitative mensuration projection of the result of optical microscope, electron micrograph, at interval, density etc. and the shape of confirming section.
Then, describe about contacting on the contact site of a plurality of projections that the present invention relates to and membranaceous encapsulant.
The concrete grammar that a plurality of projections that the present invention relates to are arranged on the vessel can adopt for example corresponding position on the vessel surface of mould, form projection by etching and processing, sandblast processing and electrosparking, perhaps by the mould cut is provided with cancellous projection.In addition, also can with the contact site of the membranaceous encapsulant of vessel on use light reactive resin to carry out the tracing of optics, with retouch into picture cut or etching and processing forms projection.The section configuration of described projection, highly, at interval, the configuration feature of projection such as density can be by selecting, control to obtain desired projection to imposing a condition of these projection producing devices.
There is no particular limitation for a plurality of projections that the present invention relates to and the concrete cladding method of membranaceous encapsulant, and the pressing component that for example can adopt existing use to be made by rubber-like elastic body and teflon plate carries out deposited method.The vessel with rigidity of the formation powder accepting container that the application is related to and soft membranaceous encapsulant seal deposited the time, and the push action that both sides are pressed together is to obtain the key element of deposited effect reliably.
The vessel of the powder accepting container that the present invention relates to and membranaceous encapsulant are undertaken deposited the time by heat-sealing, the melting point or the softening point of resin that constitutes vessel is higher 5～50 ℃ than fusing point, the softening point of the sealant that constitutes membranaceous encapsulant, therefore can keep when keeping fissility swimmingly because the deposited shape that causes the projection front end that is out of shape with not destroying.
In addition, the mensuration of the softening point of the resin of formation vessel for example can adopt the melting point analyzer to measure, in the mensuration machine of melting point analyzer CFT500 type (Shimadzu Seisakusho Ltd.'s manufacturing) etc., drop into the resin sample of ormal weight particularly, and then measure softening point.
Particularly the projection front end forms and can't damage like that, even carry out the repeated use of container repeatedly, also can keep and guarantee homogeneous and firm connectivity all the time for the vessel of membranaceous encapsulant, the projection tab that in addition, also can stop to take place to produce by breakage is effectively sneaked into when packet powder in container and is accommodated in the powder, thereby causes powder to accommodate the low situation of quality of goods.
Below, describe about the resin material of the formation vessel 201 that the present invention relates to.
The resin material of the vessel 201 that manufacturing the present invention relates to if shapable thermoplastic resin just there is no particular limitation, polypropylene (PP), tygon (PE), ABS resin, high impact tygon (HIPS) etc. are arranged particularly, preferably use polypropylene, tygon and high impact tygon.
As the shaping of the vessel 201 that the present invention relates to, can adopt for example injection molding method or hollow forming method, the resin that uses in these manufacturing process can adopt resin noted earlier.No matter in any method, do not use all material, when particularly being used as the toner accepting container, the impact during for impact when transporting or use, and also can be damaged when reusing, preferably having physical parameters such as melt index or density is the material of the value in the certain limit.
In the injection molding method,, therefore must have the flow characteristics of appropriateness owing to there is the method for in the slit of mould, injecting resin.Therefore, the preferred value of using melt index as polypropylene for example in the scope of 1～30g/10min, density is at 0.94～0.97g/cm as tygon
3Scope in resin material.Melt index is during less than this scope, it is bad that flowability becomes, uneven being filled in the mould, the container outer wall problem of heterogeneity undercapacity that becomes has taken place in the result, melt index is during greater than this scope, and resin material becomes and is easy to flow, though homogeneity improves, but thermal stability reduces, and all is not suitable for carrying out reusable container under the sort of situation.
The hollow forming method be with the resin effusion in mould, under the state of being clamped by mould, in resin, be blown into pressurized air, resin is expanded closely contacts with mould, make its cooling curing again and the method that is shaped.
In this method, if the value of using melt index as polypropylene for example in the scope of 0.1～4g/10min, density is at 0.94～0.97g/cm as tygon
3Scope in resin material, just can obtain good effect.Melt index is during less than this scope, the resin of melting state is difficult for flowing, therefore be difficult to carry out the expansion of homogeneous at the engineering phase that expands by pressurized air, the outer wall of the container heterogeneity that becomes, the impact stability of container reduces, melt index is during greater than this scope, owing to be easy to the effusion state labile that flows, particularly store resin easily in the lower end, therefore the upper and lower thickness of container outer wall has produced variation, the result has taken place to impact the problem that stability reduces, and all is not suitable for carrying out reusable container under the sort of situation.
In addition, again when vessel applies impact, be preferably in 0.1～30 in order not make its damaged Izod formula impact value.Izod formula impact value is hour breakage by impact easily, therefore is unsuitable for reusable container.If in addition, Izod formula impact value more than certain limit, just can bear in the use in hit, promptly carries out vessel in the reusable logistics operation and estimated the impulsive force that is subjected to, so Izod formula impact value is preferably in the above-mentioned scope.
For example, the resin material used as the vessel that the present invention relates to and the high density polyethylene of a preferred example that uses, its density is at 0.94～0.97g/cm
3Scope in.The assay method of density is to measure according to JIS K 7112.Very easy of the method for particularly using picnometer.

Below, describe about the resin material of the formation container that the present invention relates to.
If the resin material of the formation container that the present invention relates to is that just there is no particular limitation for the thermoplastic resin that can be shaped, polypropylene (PP), tygon (PE), ABS resin, high impact tygon (HIPS) etc. are arranged particularly, preferably use polypropylene, tygon and high impact tygon.
As the manufacturing process of the container that the present invention relates to, can adopt for example injection molding method or hollow forming method, the resin that uses in these manufacturing process can adopt resin noted earlier.No matter in any method, do not use all material, when particularly being used as the toner accepting container, the impact during for impact when transporting or use, and also can be damaged when reusing, preferably having physical parameters such as melt index or density is the material of the value in the certain limit.
In the injection molding method,, therefore must have the flow characteristics of appropriateness owing to there is the method for in the slit of mould, injecting resin.Therefore, the preferred value of using melt index as polypropylene for example in the scope of 1～30g/10min, density is at 0.94～0.97g/cm as tygon
3Scope in resin material.Melt index is during less than this scope, it is bad that flowability becomes, uneven being filled in the mould, the container outer wall problem of heterogeneity undercapacity that becomes has taken place in the result, melt index is during greater than this scope, and resin material becomes and is easy to flow, though homogeneity improves, but thermal stability reduces, and all is not suitable for carrying out reusable container under the sort of situation.
The hollow forming method be with the resin effusion in mould, under the state of being clamped by mould, in resin, be blown into pressurized air, resin is expanded closely contacts with mould, make its cooling curing again and the method that is shaped.
