Description

Brush manufacturing equipment, brush body clamp and method for manufacturing brushes

The invention relates to a brush manufacturing equipment, in which the brush body is further processed, the brush body has an opening for accommodating and fixing the bristles, and the brush body is a part of a brush to be manufactured.

In addition, the present invention relates to a brush body holder applicable to the above-mentioned brush manufacturing equipment, and a method for manufacturing a brush.

Brush manufacturing equipment is a high-precision work machine that manufactures and further processes brush parts on several continuous workstations. The brush itself has a brush body, and the brush body of the toothbrush includes a handle, a neck, and a head. The head has openings arranged in a predetermined hole pattern, and the bristle bundles are plugged into the hole pattern. These bundles of bristles are then fixed on the brush side. The so-called "plug hole" operation can be performed on the entire brush body or a part of the brush body, such as a holding sheet, which has the necessary openings for the bristle bundles. Plug this retaining sheet into the hole and connect it to the rest of the brush body. This can be achieved by squeezing or pre-fixing the rest of the brush body. The present invention relates to components for both the holding sheet and the finished brush body or brush body. Brush manufacturing equipment divided into further processing. The brush body itself having an opening through which the bristles can be inserted or a retaining sheet with bristles and the retaining sheet or, in general, a prefabricated part that will participate in defining the brush body in the future, will be referred to as a brush body hereinafter. The brush manufacturing equipment of the present invention described below does not limit the manner of fixing the bristle bundles to the brush body. It can be fixed by anchor or without anchor.

In addition, the present invention relates to a brush manufacturing equipment that performs one or more of the following steps when manufacturing bristles: plugging holes, fixing the bristles to the brush body, and processing (trimming, rounding) the ends of the bristles.

Brush manufacturing equipment must be designed to be extremely flexible, meaning that such brush manufacturing equipment must be capable of being quickly retrofitted. As the number of brushes to be prepared increases, the cycle becomes faster. The brush body must be positioned with the highest accuracy when the equipment is running at high speed. This means that when the equipment needs to be adapted to the new brush, the positioning unit must be adjusted precisely at each station.

The point is that the positioning unit for clamping the brush body to the corresponding processing station is precisely adjusted. However, since the brush bodies have different external geometries on the outer peripheral edges (side edges) of the brush bodies, adjustment is difficult.

It has been suggested to feed the brush body into the brush holder in advance rather than inserting the device to form a unit. In this case, the brush holder has a relatively simple outer profile for the brush manufacturing equipment to get stuck relatively easily, so that centering and positioning operations can be performed quickly. important The reason is that although several different brush bodies have different receiving profiles in different brush body clamps, they have individual receiving modes. However, different brush body clamps have the same contour on the parts where the brush body clamps are positioned and held on the brush manufacturing equipment. In this way, despite the existence of different brush bodies, the complicated positioning unit adjustment operation can be completely eliminated or simplified.

For this reason, these conceived brush holders have openings that taper and taper slightly from the front of the brush holder toward the back, and relative to the external geometry of the brush body to be inserted into the openings, The opening size is insufficient. Thereby, the brush body inserted from the front is held like a wedge.

An object of the present invention is to provide a brush manufacturing equipment, a brush body holder, and a manufacturing method that can further simplify and speed up the manufacturing of a brush.

The solution to achieve the object of the present invention is a brush manufacturing equipment, in which the brush body is further processed, the brush body has an opening for receiving and fixing the bristles, and the brush body is a brush to be prepared A part of the brush body has a back surface and a front surface. After the brush is made, the bristles protrude from the front surface. The brush manufacturing equipment includes a brush body clamp, in which at least one brush body can be detachably inserted into each brush body clamp to form a form-fitting temporary unit. The unit is fed into the equipment, passes through the equipment and is Remove the device. The brush manufacturing equipment further includes equipment End positioning unit, which holds the unit by holding the brush holder and positioning the unit in the device when the brush body is further processed, wherein the brush holders are designed to have mechanical stops In order to prevent the corresponding brush body from detaching from the brush holder from the back surface toward the front direction.

The present invention is provided with a large number of brush body clamps by brush manufacturing equipment. This means fixtures that are not permanently installed in the equipment and become part of the equipment. More precisely, each brush body clamp together with one or several brush bodies forms a unit that passes through each station in the equipment or a single station. Therefore, these brush body clamps are temporary mobile clamps, which correspond to the brush body and not the equipment. These brush body clamps are characterized in that the brush body clamps are not inserted from the front like the conventionally designed brush body clamps, and are fastened to the brush body clamps only in a clamping manner (wedge effect) forward. More precisely, the brush holders have one or more mechanical stops that prevent the brush body from falling off. The direction in which the stopper or stoppers act can be most simply defined as the direction from the back of the brush body to the front. In addition, it should be pointed out that the brush body clamp has a back surface and a front surface, and the back surface and the front surface correspond to the back surface and the front surface of the brush body accommodated in the brush body clamp, respectively, that is, the orientations of the two are consistent. The stop is used to obtain a mechanical locking effect to prevent the brush body from falling forward. This is particularly beneficial when processing the bristle bundles that have been inserted into the brush body. Because when trimming the bristle bundles or rounding the bristle bundles, it is possible to generate a pulling force that may cause the brush body to detach from the brush body holder of the brush body.

The positioning unit should only clamp the brush holder, so that it can benefit from the brush holders being always the same, regardless of the external size or external geometry of the brush body type, and without having to be realigned.

It is also possible to provide a transport unit that only clamps the brush holder and transports the unit through the device. Therefore, the conveying unit also benefits from the external shape and external geometry of the brush body fixture that is always the same and is not affected by the geometry of the brush body contained in the brush body fixture.

The transport unit may include movable jaws that laterally clamp the brush body clamps and receive the brush body clamps to move the brush body clamps toward or away from the positioning unit or units. In other words, the transport unit preferably clamps the edge (ie, the periphery) of the brush holder from the outside, but other implementation changes can also be adopted therein. For example, the brush holder can also have one or more openings, and the pins of the transport unit can be embedded in these openings in order to remove the brush body from the positioning unit and continue to transport it.

The brush body clamps are configured such that the brush bodies received in the brush body clips are held without gaps in all directions. That is, even if the brush body is inserted into the brush body holder from the back, the brush bodies will not fall off the brush body holder when the unit is raised.

In order to simplify the manufacture of the brush body clamps, and in particular to more conveniently position and transport (i.e., hold) the brush body clamps, the brush body clamps have at least one positioning unit and ( Or) The straight contact surface of the transport unit. But the better one is two. Opposite and parallel flat contact surfaces and / or openings into which positioning units and / or transport units can be embedded.

The brush body clamps may have a plate-like shape and have a receiving port for the brush body, wherein the receiving port is defined by a holding edge that catches a side edge of the brush body. The plate-like shape is easy to manufacture, and it is also convenient and securely positioned on the first plane (ie, the placement plane) on the equipment or each station of the equipment.

The receiving port may have a shape complementary to the outer periphery of the brush at least in sections. The receiving openings need not be completely complementary, rather, it is beneficial to set only a part of the section as a contact surface. This can reduce friction and reduce jamming between components. When manufacturing the brush body clamp, it is extremely difficult to contact only the part and requires high precision. Therefore, if the contact surface becomes smaller, manufacturing can also be simplified.

According to an embodiment of the present invention, the brush body clamp is designed to form an engaging connection with the at least one inserted brush body. This snap-in connection is particularly beneficial because it combines the quick insertion and removal of the brush body in the brush body clamp with mechanical locking.

The brush body clamp or a section of the brush body clamp may be composed of an elastic material such as plastic, or may be composed of metal. When the brush body is accommodated, these sections are pressed directly against the brush body and clamp the brush body. Therefore, the snap-in connection is implemented not only to achieve a form fit with the brush body, but also to further clamp the brush body.

According to a particularly simple variation, it is proposed that the plate-shaped brush body clamp be slit, which means that the gap is used to define two relatively Moving section. These sections can be separated from each other to accommodate the brush holder, and then move back and forth to maintain the brush body.

The gap forms, for example, two spaced apart sides, which are relatively elastic and flexible to form a snap connection. The gap may extend to the side edge of the brush body clamp, that is to say, except for only one side or one end, the gap extends continuously. Therefore, one side of the two side edges is elastically connected through the base edge (Steg), and is preferably connected integrally. In this case, the base edge is mainly used to realize the relative mobility of the side edges. On the opposite end, the sides form free ends, respectively.

As an alternative to the elastic design of the brush body clamp or a complementary change that can be combined with this, it is proposed that the gap continuously passes through the brush body clamp to form several sections, and these sections can also be independent parts. These sections are installed in a relatively elastic manner through at least one elastic element (especially a metal spring) in order to form a snap-in connection. In the simplest case, the brush holder is composed of two independent halves which are coupled by a deflection connection and at least one spring or, for example, by two springs. Flexibility is generated by this elastic effect, so that a snap connection can be achieved. The advantage is that the holding area does not have to be too elastic. For example, the sections or parts of the brush holder can be made of metal, thereby extending the life of the holder.

The brush body clamp has a plate-shaped bottom penetrated by the gap and a retaining edge protruding from the bottom, wherein the flexible sections are respectively Including: a section of the plate-shaped bottom and a protruding retaining edge, so that the retaining edges of the sections can be moved toward or away from each other.

When the unit composed of the brush body and the brush body clamp has been inserted, the positioning unit can optionally mechanically prevent the relatively movable sections from moving to the open position, thereby preventing the brush body from falling off.

The brush body clamp should preferably hold the brush body accommodated in the brush body clamp without gap, and of course hold it at least laterally and forward in a form-fitting manner.

The device of the present invention preferably does not directly jam the brush body during further processing. The brush body is locked in the device only by the brush holder.

In addition, the present invention relates to a brush holder for use in the brush manufacturing apparatus of the present invention, wherein the brush holder has a receiving port for a brush body to be inserted into the brush holder, and the receiving port is formed by A retaining edge definition, wherein the retaining edge has at least one stop protruding inwardly toward the front. Through this stop, the following effects can be achieved: the brush body will not be easily pulled out of the fixture during the processing of the brush body inside the brush manufacturing equipment. The brush body clamp has a slit, and the gap also passes through the accommodation port, so as to form a number of relatively movable sections, especially elastic sections. These sections allow the insertion and removal of the brush body. The equal segments and the brush body form an engaging connection that can be released without breaking, and these segments are pressed against the brush body when the brush body is accommodated.

As described in the foregoing in connection with the brush manufacturing equipment, the brush body clamp may have an elastically flexible section, and these sections form a snap-in connection with the corresponding brush body without breaking.

In particular, the brush holder has a plate-shaped bottom, and the integrally-shaped holding edge projects out from the bottom. As mentioned before, the gap divides the bottom and the retaining edge into two sections or halves, which sections or halves can be brought together or separated, so that the gap becomes larger or smaller accordingly. These sections can be relatively elastic, which is achieved by springs or through the sections being integrated at the ends under the condition of forming a U shape.

It should also be emphasized that the characteristics of the brush holder described in the introduction of the brush manufacturing equipment of the present invention can also be directly possessed by the brush holder.

The invention preferably relates to a kit composed of a plurality of brush body clamps, which have the same external geometry, but have different receiving openings for different brush bodies.

Finally, the present invention relates to a method for manufacturing a brush. The brush has a brush body provided with an opening for receiving bristles. The brush body is a part of the finished brush and has a back surface and a front surface. After the brush is made, the bristles protrude from the front surface, which is characterized by the following steps: inserting the brush body into the brush body holder, the brush body holder has a mechanical stop to prevent the brush body from detaching from the back surface toward the front Brush holder, The unit composed of the brush body and the brush body clamp is transferred to a conveying unit, which automatically feeds the unit into the brush manufacturing equipment (by a driver), and the positioning unit is used to hold the grip on the brush body clamp The unit is positioned at a further processing station, where the positioning unit only clamps the brush body clamp, and mechanically prevents such possible failures when the unit consisting of the brush body and the brush body clamp is inserted The relative moving section moves to the open position, thereby preventing the brush body from falling off. The brush body is further processed, and the unit is transported away from the further processing station and / or the brush manufacturing equipment in a manner that the brush body clamp is caught.

In the method of the present invention, the brush body clamp or the large number of brush body clamps are not part of the equipment, but are temporarily formed into a unit with the brush bodies of the brush body clamps respectively, so as to automatically (in a unit form) That is, by means of a drive, not manually, is carried through the brush manufacturing equipment and is finally taken out of the brush manufacturing equipment again.

The features described above in connection with the brush manufacturing equipment are also relevant to the method of the present invention and are equally applicable to the method.

In particular, the brush body is inserted into the brush body holder of the brush body under the condition of snap-fit connection, and is held in the brush body holder without gap. This gapless hold occurs in all spatial directions.

FIG. 1 shows a brush manufacturing apparatus 1. In this example, the brush manufacturing apparatus can perform various processing steps, and the present invention is not limited thereto. The brush manufacturing apparatus has, for example, a rotatable feeding table 5.

The feeding table is generally a cube, and the cube can rotate between four positions about the axis A. The unit composed of the brush body 8 and the brush body holder 9 is housed in the positioning unit 7 and mounted on the side of the cube. Different processing steps are performed at these four different locations, and these processing steps form a processing station.

The loading station 4 is implemented in the top position. The unit composed of the brush body 8 and the brush body holder 9 is inserted into an empty positioning unit 7 there. In particular, this is done in a fully automatic manner. The illustrated embodiment is simplified.

The next step (rotating 90 ° clockwise) is to perform the plugging on the plugging station, where a plugging operation is performed, for example, with an anchor.

To this end, the brush body 8 has a plurality of openings 20, and these openings 20 are sequentially filled with the plugging tool 10. The symbol 11 is used to indicate the bristle box, and the symbol 12 is used to indicate the separator.

After continuing to rotate 90 ° or 180 °, the free end of the bristles 15 is then processed at this position, for example by cutting and / or grinding. Finally, the unit composed of the brush body 8 and the brush body clamp 9 is taken out of the device again. This is performed at a position rotated 270 ° with respect to the loading station 4. This station is marked with the symbol 13.

Of course, the brush body and the fixture of the brush body can also be jointly removed from the feeding table and sent to other stations for reprocessing steps, where the bristles are cut or rounded, for example. It should be emphasized that the illustrated equipment is only an example. The equipment can also implement only one of the aforementioned processing steps or other processing steps, and it does not have to be implemented in a rotatable feeding table. Several stations connected in sequence through one track can also form the device of the invention.

Figure 2 shows the positioning unit 7 mounted separately on a feeding table, which here forms a transport unit. The positioning unit 7 is fixed on the feeding table 5 during work and is a fixed component of the equipment, while the unit composed of the brush body 8 and the brush holder 9 is only temporarily located in the equipment, and is sent before and after processing Move in or out of the device.

The brush body 8 is a brush body made by injection molding technology and has a large number of openings 20. The bristles 15 are plugged into the openings 20.

The brush body clamp 9 is implemented as a standard piece, and the brush body clamp 9 is generally plate-shaped and has a flat back surface (also referred to as a bottom surface). The back surface is located on the same side as the back surface of the brush body 8, and the brush body 8 has a top surface as shown in FIG. 2. This top surface is the side where the bristles bulge after the brush is made (see Figure 1).

Correspondingly, the brush holder 9 also has a top surface that points to the same side as the top surface of the brush body 9.

The brush holder 9 shown in more detail in FIG. 4 has a simple structured external geometry and includes a side edge 20 which has a large number of parallel flat contact surfaces 22, 24. On these contact surfaces 22, 24, it is very easy to grasp or align the unit.

The brush body 8 is held in the brush body clamp 9 by a snap connection.

For this purpose, the brush holder 9 includes an accommodation opening 30 that faces only the front (see Fig. 4), only the back (see Fig. 5), or the front and back (Figs. 4 and 5). (Combined) open. The accommodating opening 30 is defined by a holding edge 32 that abuts at least in sections on the side edge 34 of the brush body and presses against the side edge 34.

The inner side of the holding edge is provided with a geometric shape at least in sections. The geometric shape is complementary to the shape of the side edge and the outer periphery of the brush body. Therefore, the brush body 8 is fixedly installed in the brush body holder 9.

The section of the brush holder 9 (referred to herein as the section of the retaining edge protruding upward with respect to the plate-shaped bottom) adopts a flexible design. In addition or as an alternative, the entire brush body clamp 9 can also be formed entirely by a flexible section.

In the embodiment as shown in FIGS. 4 to 6, the brush holder 9 is designed with a slit. The longitudinal slit 41 communicating with the opening 42 extends to the side edge of the brush body clamp, thereby forming two sections that can move relative to each other, here are two side edges 44 and 46, and these side edges 44 and 46 penetrate the base edge 48 interconnected. The side edges 44 and 46 have holding edges 32 (see FIG. 4) and can be moved together or separated in the direction of the arrow in FIG. 5 to move relative to each other. This shape allows the brush body 8 to be inserted into the accommodation port 30 from above or in the longitudinal direction (see the arrow in FIG. 4). The opening 42 can also be used as a positioning hole in the device.

In the embodiment as shown in FIG. 5, the slit 41 is expanded into a back opening so that the brush body 8 can be inserted from the back, and in the embodiment as shown in FIG. 6, the slit is narrowed uniformly.

In addition, it should be emphasized that the retaining edge 32 can also be divided into several small finger-shaped protrusions, instead of having to consist of two strip-shaped protrusions that abut against the brush body 9 along almost the entire side edge. The gap also extends through the receiving opening and the holding edge 32, so that the holding edge protruding integrally from the plate-like bottom of the brush holder 9 also has several sections.

The snap-in connection is designed so that the holding edge 32 abuts on the top surface of the brush body 8. Specifically, the holding edge 32 has A stop 40 (see FIG. 4) protruding inward in the region is implemented in the form of a lip. This prevents the brush body from being detached from the brush holder 9 upwardly (ie, from the back to the front).

The section 51 of the brush holder 9 abutting on the top of the brush body can further serve as a stop and positioning aid in the direction of the arrow in FIG. 4, and can also have a stop 52 on the top surface of the section 50. The stopper 52 prevents the brush body 9 from coming out of the brush body holder.

In this case, the relatively movable elastic sections are the two side edges 44 and 46 elastically connected through the base edge 48, but the gap 41 may not be provided, and only the edge 32 is adopted to adopt an elastic design.

Generally speaking, the brush holder can be made of metal or plastic, and this applies to all embodiments. It can also be manufactured using 3D printing technology (rapid prototyping).

In the embodiments as shown in FIG. 7 and FIG. 8, the brush body holder 9 adopts substantially the same design as that of FIGS. 4 to 6, but the two sides 44 and 46 are completely separated instead of being integrated, and there is no basis Edge 48. Thereby, a plurality of independent sections or sections are formed through the gap extending through the brush body clamp 9, and these sections or sections are pre-tensioned toward each other by the elastic element 50 (here, a metal tension spring). Here, the aforementioned snap connection can also be formed between the brush body 8 and the brush body holder 9.

The shape of the brush holder is implemented to be equivalent to the embodiment shown in FIGS. 4 to 6.

The embodiment shown in FIG. 9 is different from the embodiments shown in FIGS. 7 and 8 only in that the two are separated from each other and formed. The sides 44, 46 which are independent parts are connected to each other at one end through a bearing or a hinge. An elastic element 50 (here, for example, a U-torsion spring) brings the two sections together to form an engagement mechanism.

Of course, a plastic hinge with elasticity can also be provided instead of the spring shown in the figure.

Generally speaking, the brush holder can also be implemented as a multi-component injection molding casting. The softer component connects the two halves of the harder component.

The same brush holder can always be manufactured in the first step, especially by injection molding technology, and then these brush holders are individually adjusted (that is, reprocessed, especially by milling) to suit the corresponding brush body. Among them, for example, only individual milling or expansion of the receptacles. Such a method for manufacturing a brush holder is the method of the present invention.

In the embodiment as shown in FIG. 10, the brush body 8 is not a complete brush body as in the previous embodiment, but a small disk-shaped member provided with an opening 20. These disk-shaped members are mounted on the electric toothbrush and The electric toothbrush is driven.

A plurality of brush bodies 8 are inserted into the plate-shaped brush body holder 9 from the back side (here, from below).

As shown in FIG. 11, the brush holder 9 also has a stop 40 here, which is close to the top surface and is implemented as an edge protruding inward toward the accommodation port.

As in the above-mentioned embodiment, in this embodiment, the accommodation port 30 is also designed to be at least segmentally complementary to the outer periphery and outer peripheral shape of the brush body 8. In the illustrated embodiment, a plurality of depressions 60 are provided in the area of the holding edge 32.

In this embodiment, the stopper 40 is also used to prevent the brush body 9 from detaching from the brush holder from the front.

Different from the foregoing embodiments, this embodiment does not provide a snap-in connection, but prevents the brush body 9 from falling downward through a clamping effect. Specifically, the receiving opening 32 is slightly undersized relative to the outer periphery of the brush body 8. Of course, this embodiment may also be provided with a snap connection.

As mentioned above, the brush holder 9 of this embodiment also has a number of straight contact surfaces 22, which are also partially pointed in opposite directions in pairs to facilitate the formation of the brush body 8 and the brush holder 9 Positioning of units and simplified manufacturing.

It should be noted that the external geometry of the brush holder 9 is always the same in the sections (sides 44 and 46) where the positioning unit 7 abuts, but the brush holder 9 is in the receiving opening. The area 30 adopts different structures so that different brush bodies 8 can be accommodated.

The accommodating and fixing of the units in the equipment or at the stations is shown in Figures 2 and 3.

The positioning unit 7 has a flat placing surface 62 on which the brush holder 9 is placed with the flat bottom surface of the brush holder 9.

The holding shoe 64 on the placement surface 62 has a cantilevered upper edge 66 that snaps into a plate-like section of the brush holder 9 in a manner similar to a snowboard fixture. At the other end of the brush holder 9 opposite to this, a deflectable or movable fastener 68 catches the top surface of the plate-like section of the brush holder 9. After the unit is placed, these fasteners 68 are moved towards the retaining shoe 64, for example by pre-tensioning a spring or by hydraulic, pneumatic or electric means. In the illustrated example, the fastener 68 is pneumatically deflected or moved to the open position, and the spring pressure moves the fastener 68 to the closed position.

The fastener 68 may further clamp the side edge of the brush body clamp 9 laterally, and push the brush body clamp 9 forward into the holding shoe 64 and against the holding shoe 64.

Since the side edge of the brush body clamp 9 has an oblique angle forming a flat contact surface 24 in the contact area in contact with the fastener 68, the brush body clamp 9 is also held laterally and aligned between the two fasteners 68.

After the unit composed of the brush body and the brush holder is inserted, the fastener 68 of the positioning unit 7 catches the sections in the form of the side edges 44 and 46 from the outside, thereby preventing the relatively movable sections of the brush holder 9 from outward Move to the open position, thereby mechanically preventing the brush body 8 from being taken out / pulled out.

FIG. 13 illustrates a conveying unit 70 having a claw 72 that can move toward or away from each other, and the claws 72 hold the brush body clamp 9 at the flat contact surface 22.

As shown in FIG. 10, the brush holder 9 has a beveled edge 74 on the transition area between the side edge and the bottom surface for the claw 72 to be locked, and when the brush holder is required to be located on a flat surface, the brush holder can be clicked into 9 下。 9 below.

As shown in FIG. 13, the conveying unit 9 forms, for example, a brush holder 9 on the brush body 8 to form a unit.

FIG. 12 also shows the transport unit 70, but in this example, the transport unit 70 is not used to form the above unit, but is used to transport the unit into or out of the apparatus of the present invention. Here, these units enter or exit the station or from one station to the next station, of which the brush body 8 may of course have been plugged or otherwise processed further.

Figure 14 shows an optional plughole station using these units. Here, the bristles are not cut by the plug hole, but the bristles or tufts are unrolled from at least one reel 80 and inserted into the opening 20. The bristles 15 or tufts of bristles are then cut from the bristles with a blade 82. If the hole is plugged from the back, the brush holder 9 must have a correspondingly large opening on the back of the brush holder 9 in order to reach the opening 20 in the brush body 8. For the sake of simplicity, the brush holders 9 are not shown here, but the brush bodies 8 are also permanently located in the brush holders of the brush bodies 8 at this station.

In the embodiment as shown in FIG. 15, the brush holder 9 is composed of several parts, that is, two separately made side edges 44 and 46, and a connecting plate 80 is installed on the top surfaces of the side edges 44 and 46. The side edges 44 and 46 are located on the bottom plate 82, and the bottom plate 82 may have a complementary arch structure matching the back surface of the brush body 8.

In the front end region of the brush body 8, the connecting plate 80 protrudes slightly from the brush body 8 to form a stop 32.
