Description

For manufacturing the method and apparatus of hairbrush or brush and the carrier of hairbrush or brush

Technical field

The present invention relates to the method and apparatus for manufacturing hairbrush or brush, the hairbrush or brush have to be moulded by thermoplasticity Expect constitute carrier, the carrier have at least one permanent opening, at least one bristle elements be embedded in the permanent opening and No anchorage is fixed therein.Moreover, it relates to a kind of for hairbrush or the carrier of brush, the carrier is by thermoplastic It constitutes and there is at least one permanent opening, the bristle elements of no anchor are embedded in the permanent opening.

Background technique

When manufacturing hairbrush, particularly toothbrush and housework is brushed, actually implement two methods, that is, by anchor (Bao Jin Belong to plate or wire loop) or without anchorage fastening brushing cluster.From use anchor different, no anchor method regulation: not being to fold brushing cluster and tight Gu at it in brush carrierIn folding position on, but locked at one end through bonding or heat On brush carrier.Here, the method regulation commonly implemented in practice: brush carrier has opening, by the brushing cluster It is inserted through these openings.Then brushing cluster is added from stretching in the opening and on the back side of brush carrier with its back end Heat.Therefore the thermoplastic material of bristle melts, thus bristle mutually merges in terms of material and generate thicker portion, single brush Hair cannot be drawn forward out due to the thicker portion.Usually so that many brushing clusters is liquefied in back side by hot wind or hot formed punch, makes The material for obtaining each brushing cluster mutually merges and generates a kind of layer by liquefied bristle ends in back side.Then the back side is carried out Covering, particularly splash.

The shortcomings that this solution, is: due to the necessary covering of this back side it is therefore, it is necessary to pay process aspect and The huge extraneous expense of equipment aspect.It should be noted herein: being exactly to set the transition face between adjacent layer in the case where toothbrush Be calculated as it is as gapless as possible, to avoid hygienic issues.

The concept of " brush carrier " is construed as the component of finished product of brush, which carries bristle or brushing cluster.Bristle Carrier can be entire brush body herein, include the portion of handle, neck and the one-piece injection on head in the case where toothbrush Part, or can also be only the prefabricated component part of later period brush body.In aftermentioned situation, brush carrier is usually by heat The thin plate that thermoplastic plastic is constituted, the thin plate are provided with one or more for filling opening for one or more bristles or brushing cluster Mouthful.After bristle is filled and fastened, then laminal brush carrier is embedded in prefabricated brush body, the brush body example As having the respective recess for lamellar brush carrier.As alternative furthermore, it is often the case that: to lamellar brush Bristle holder carries out injection encapsulating and thus generates the brush body of the rest part including prefabricated brush carrier and injection.

672 579 A5 of CH proposes a kind of method for brushing cluster to be fastened in brush carrier by thin anchor slab. This means that: brushing cluster is folded, and thin anchor slab is located in fold domain, which is pressed into the wall of permanent opening simultaneously And thus finally brushing cluster is fixed on brush carrier.However in order to which more preferably the opening on the end side of brush carrier is sealed It closes, prevent bacterium and mould are from breeding herein and breeding, it should protuberance is inwardly extruded on brush carrier, the protuberance is around solid Fixed opening extends and the protrusion from end side.However brushing cluster itself is logical not by this forming fastener of protuberance Anchor itself is crossed to be fastened.Each brushing cluster is driven into brush carrier via filling tool one by one, the filling Brushing cluster through folding is pushed through pipe by tool.Described pipe itself then has heating device, the heating device on its end side It only sticks on the protuberance and the protuberance is made to melt or be plasticized and then radially-inwardly squeeze.

Other than above-mentioned a possibility that being fastened on bristle or brushing cluster on brush carrier without anchorage, theoretically also generate Other method, however this method is from having not been able to implement in practice, that is, brushing cluster is pierced into brush carrier, which carries Body, which has, to be open and is preheated.After brushing cluster is pierced into soft brush carrier, by press to brush carrier before it (brushing cluster is stretched out from the leading flank) applies pressure on side, so that soft material is extruded around the edge and opening of opening Cross section be reduced.Introduce several schemes thus below.

198 53 030 A1 of DE is provided: brushing cluster has the bristle mutually melted as thicker portion in its back side.Bristle carries Body possesses opening, the protrusion of the bar shape of heating device before brushing cluster piercing at not contact openings edge in the case where be inserted into In these openings.Pass through this radiant heat, the inside edge local pyrexia of opening.Brush carrier reaches in the edge region makes group The temperature of knitting variation, such as softening temperature.It is increased by temperature, should be reduced in the cross section Kong Qi, so that brushing cluster is being pierced into Shi Yiding enters in wall.Then it will be pushed into the opening with the brushing cluster of thicker end after removing heating device, Wherein, thicker portion is greater than open cross-section in cross-section, so that the thicker portion enters restriction and surrounds the open edge Soft region in, in i.e. corresponding wall.Next still shape the leading flank of brush carrier using formed punch, so that the bristle The material of carrier is pressed towards brushing cluster and is fixed.

A kind of similar method as known in US 5 224 763, in the method, brush carrier have crowned protrusion Open edge.It is heated herein also by edge of such as under type to the opening, that is, the heating element of bolt shape protrudes into institute It states in opening or carries out operation using hot wind.Thicker end of the opening itself from cross section less than brushing cluster, so that should Brushing cluster is fixed therein later in the wall for being pierced into soft opening.Then holder for brushing cluster squeezes heated ring Around protuberance so that additional material can be used for arrive the closure of openings of the transition department of the end side of brush carrier.

A kind of method as known in 0 355 412 A1 of EP, in the method to the thicker end and/or brush of brushing cluster The edge of opening in bristle holder is heated, wherein size and temperature are chosen to, so that the edge of opening is at thicker end Portion, which is pierced into, to be pressed to inside later and is similar to the thicker end encirclement and shape lock in being connected so like that Ground is closed to be accommodated.

0 472 557 B1 of EP is proposed: utilizing being made of plastics for heated, with pin formed punch indentation plate shape In the brush carrier of plate shape, so that the pin constitutes the opening for accommodating brushing cluster.Then brushing cluster is embossed into , in still hot opening, and there is melt around the thicker portion of brushing cluster.Furthermore template can be pressed to brush carrier Upside, also to make melt forming.Herein particularly preferably: protrusion or grand is stretched out on the upside of also unfashioned brush carrier It rises, these protrusions or protuberance constitute the material that can be used as pressing to the direction of opening.

In the method according to 34 22 623 A1 of DE, the brush carrier and bristle that plate shape will be designed as and be not open Cluster welding, these brushing clusters are made of plastics identical with brush carrier.Heating tool brush carrier and brushing cluster also It is moved between the side not being welded to each other, so that the two melts.It then will be in the material of the fusing of brushing cluster indentation brush carrier.

The bristle of bristle elements 12A, 12C and 12D can be made of thermoplastic, especially PA, PBT, polyester, copolymerization Ester or polypropylene.

Carrier 10 is fixed in holder 18.The holder 18 makes for carrier 10 to be maintained in corresponding work station Corresponding procedure of processing must can be implemented.

In Fig. 1, procedure of processing is to equip at least one bristle elements 12 for carrier 10.Have thus and schematically shows Equipment Station 20, using the equipment Station can will corresponding bristle elements 12 be embedded in carrier 10 in permanent opening 22 in.

Permanent opening is at this from extending into the side of carrier 10 more than prespecified depth in the carrier 10. It is designed as blind hole in the embodiment of Fig. 1 and 2.

Bristle elements 12 and permanent opening 22 design are as follows: bristle elements 12 (almost) nothing frictionally can be inserted into permanent opening In 22.The especially cross sectional dimensions of permanent opening 22 foot 14 or bar portion 16 the cross sectional dimensions that is greater than bristle elements.

Therefore, bristle elements 12 are not fastened on the load first after it is embedded in carrier 10 in the first procedure of processing In body 10.Also anchor is not used bristle elements 12 are fixed in the carrier.

After carrier 10 is equipped with one or more bristle elements 12, the second procedure of processing shown in figure 2 is carried out. The procedure of processing is carried out by the pressing mold 24 schematically shown.

In the second procedure of processing, carrier 10 is also secured in holder 18.What is be related in this case can be load Body 10 also is located at the same holder 18 therein in the first procedure of processing；Continue in this case or by carrier 10 It shifts to next machining workstation or the second procedure of processing carries out on the same position, the first procedure of processing is also in the position Set progress.However also relate to other holders 18；Equipped carrier 10 is by conveying equipment in this case It is further mobile.

Use two pressing molds 24 in the second procedure of processing, these pressing molds from opposite side press to carrier 10 away from each other Side surface 26, that is, act on the side for being different from bristle elements 12 and extending out from the carrier 10 on it of carrier 10 Side on.

Pressing mold 24 designed in the way of formed punch and can along arrow P direction towards the side surface of carrier 10 26 into It gives.Here, direction P (pressing mold is fed along the direction) is approximately perpendicular to the longitudinal axis L of permanent opening 22.

According to corresponding practical structures situation, the moving direction of pressing mold 24 is relatively orthogonal to the longitudinal axis L of permanent opening 22 Certain offset in direction can be suitable.However the longitudinal axis L of the relatively fixed opening of principle upper die 24 tilts always It ground and is substantially transversely squeezed.The component perpendicular to longitudinal axis L effect of moving direction is more vertical than being parallel to this herein The component of axis effect is big (preferably much bigger).

Pressing mold 24 is forced with very big to carrier 10.According to the rim condition in structure, the pressure of 200bar or more can be used Power, preferably at least 400bar.

Action time of the pressing mold 24 on the side surface of carrier 10 is at least 5 seconds, particularly at least 6 seconds and maximum For 15 seconds, particularly it is up to 10 seconds.

As the exercising result of pressing mold 24, the material of carrier 10 is plastically deformed.As can be seen in Fig. 2, The material of carrier 10 is transferred in permanent opening 22, so that the cross section of the permanent opening 22 reduces.Specifically, permanent opening 22 inner wall sticks in the bristle elements 12 being embedded within, the bristle elements be thus fixedly secured in permanent opening and It is thereby secured on carrier 10.

If bristle elements 12 are equipped with foot 14, this improves fixed function, this is because in addition in permanent opening 22 Inner wall and bristle elements 12 between clamping action except also generate mechanical caging effect.

It is flowed for the ease of the material of carrier 10, is preferably heated to the temperature for being conducive to this.It sets for this purpose It is equipped with heating device 30, can be acted in the region on carrier in pressing mold 24 using the heating device and heat is placed in carrier 10 In, especially in the region of respective side surface 26 and in the material area of 22 side of permanent opening being located under it.

Heating device and pressing mold 24 can be provided separately in principle, to be for example placed in energy by radiating or vibrating In carrier 10, which leads to local heating there.

It is possible thereby to which the material of carrier is heated to desired temperature and then carries out operation using " cold " pressing mold.

However it is preferred that heating device 30 is integrated in pressing mold 24, more specifically near compressive plane, pressing mold 24 is with this Compressive plane effect is over the carrier 10 (i.e. based on direction P near the front end face of pressing mold 24).

In the embodiment shown in fig. 2, heating device 30 is designed as electric heating equipment, i.e. resistive heating device, peace On pressing mold 24 or it is integrated in.

In a preferred embodiment, the compressive plane of pressing mold 24 is heated to by heating equipment molten lower than 10 material of carrier Change the temperature of temperature.Especially it is the highest 85% of the corresponding fusion temperature of 10 material of carrier calculated in degrees celsius.If carrying Body material is for example with 100 DEG C of fusion temperature, then the temperature of pressing mold 24 is 85 DEG C of highest when it presses to carrier 10.

(carrier 10 is heated to the temperature to the temperature in the region of its side surface 26, in this region pressing mold pressure To side surface 26) should not only be lower than or significantly lower than 10 material of carrier fusion temperature, but also should be in carrier material In the range of glass transition temperature.Using for example the extremely high pressure of 600bar or more can by carrier 10 side surface 26 area It is heated only to be located at the temperature of limiting temperature or more in domain, which has in carrier material is more than or equal to 300 It is 60%, particularly 80% calculated in degrees celsius of the glass transition temperature of the carrier material in the case where degree Kelvin.So And it is preferred that the limiting temperature about or bottom line be higher than glass transition temperature.In glass transition temperature less than 300 Kelvins In the case where the carrier material of degree, heating temperature is the maximum 50% that glass transition temperature or more is calculated with degree Kelvin.

Generally speaking it is emphasized that: carrier 10 should not be made close to its fusion temperature, but be significantly away from the fusing Temperature and close to glass transition temperature, this is not only to be directed to shown embodiment.Especially heating temperature and therefore Temperature in the region of pressing mold 24 on side surface 26 should not be greater than the glass transition temperature of carrier material or more 15%.

One embodiment of the present invention provides: the side surface 26 in the region of pressing mold 24 is heated to therefore carrier 10 130 DEG C of maximum 140 DEG C of temperature, particularly maximum are preferably heated in the range of 100 to 115 DEG C.In this case, special It is not to use polypropylene, PET (85 to 90), ABS and SAN as material for carrier.It can be enough and beneficial in the case where PET : side surface is heated to the only temperature in the range of 85 DEG C to 90 DEG C.

If carrier material is such as determining PP type (Polypropylenart) (vitrifying in these PP types Transition temperature be not higher than environment temperature) as material, then can be omitted the heating to pressing mold 24, however be not necessarily required to It is such case.Here, it can be beneficial for being still minimally heated to slightly higher than glass transition temperature, however it is same Sample is substantially less than fusion temperature again.If if need not or not heated in the case where such carrier material, then only passing through Apply aforementioned pressure and reduces permanent opening 22 in cross-section with the action time.Herein The pressing mold 24 of no heating device or the pressing mold 24 with heating device can be used, wherein the basic un-activation of the heating device.

In order to accurately control corresponding movement and temperature, the equipment has control device not shown here, utilizes The control device not only controls heating temperature, but also controls the pressure and motion process of application.

For motion process, variant schemes that is different, being combined with each other can have.

Pressing mold can with otherwise be heated to keep constant that constant or it is in the side table with carrier in desired running temperature It is just heated after the touching of face 26.

Pressing mold can be sticked on side surface 26 with low-pressure in the first phase, so that the material to carrier 10 adds Heat, and then moved into the side surface against side surface 26 and if necessary in second stage with above-mentioned high pressure. Optionally, pressing mold 24 can continuously press to side surface 26 with prior defined power, so that same pressure is consistently Effect is there.

Controllably pressing mold can be loaded to the side surface of carrier 10 26 on power, time and/or stroke.

The following contents is independently applicable in carrier material: in the feed motion of 24 opposite carrier 10 of pressing mold pressure and when Between upper controlled feed motion and/or controlled feed motion in pressure and stroke can be advantageous.It is especially following interior Appearance is beneficial: in the first stage of feed motion, by 10 material of carrier in pressing mold 24, (pressing mold is located at the carrier It is interior) region of lower part is heated to above the temperature of limiting temperature.If carrier material possesses the glass transition of 300 degree Kelvins or more Temperature, then this limiting temperature be about the glass transition temperature of carrier material or less 60%, particularly 80% (with degree Celsius Measurement).However limiting temperature is preferably about glass transition temperature, reach when necessary glass transition temperature or more with degree Celsius 20% calculated.In the subsequent second stage of feed motion, it is plastically deformed carrier 10 in 22 side of permanent opening, so that The inner wall of the permanent opening 22 is pressed towards bristle elements 12 and the bristle elements is fastened in the permanent opening 22.

After the action time of pressing mold 24 terminates, it is moved back to these pressing molds again, and bristle elements 12 are reliably solid It is scheduled in carrier 10.

Then carrier 10 can be taken out and if necessary it is continued to process.Such as it can be in order to which toothbrush be to bristle Continue to process, such as is cut into desired profile.Such as it also can use plastic material and carrier 10 infused Encapsulating is penetrated, to secure it on handle or handle.

In a kind of unshowned modified embodiment, a unique pressing mold 24 also can be used, the pressing mold is in unilateral side It is applied on carrier 10.Then carrier 10 is pressed to support by pressing mold 24, the carrier supported is on the support.The support Effect can be that large area supports, so that the effect of the inner wall of permanent opening 22 only unilateral plastic deformation or the support It can be the small area support similar to the contact area of pressing mold 24, so that the effect by the reaction force of support occurs such as It is deformed using same bilateral as two mutually just relatively opposed pressing molds.It can also set in the holder in this case Set heating device 30.

In other unshowned modified embodiment, also can be used more than two pressing molds, such as three each other The pressing mold being arranged at 120 ° of angles.

Generally speaking, if using more than one pressing mold, then these pressing molds are symmetrical.
