- the invention is applied to brushes of a substantially flat type wherein the ferrule consists of a metal or plastic strip, closed in a ring substantially of any shape: rectangular, round, polygonal, etc.
- the state of the art includes ferrule-assembly machines which are fed separately with bundles of bristles, which constitute the end part of the brush, and with ferrules onto which the bundles of bristles are attached, normally glued.
- the ferrules normally consist of metal or plastic strips closed in a ring, the edges overlapping in correspondence with one of the narrow sides so as to constitute a closing ridge.
- the ferrules generally have perimeter ribs and writings or markings to identify the brush, such as the size, brand, type of bristle or other information, which define a univocal assembly position for the bundle of bristles and the handle with respect to the ferrule itself.
- the function of the ribs is both to stiffen the ferrule and as an anchor for the glue used to attach the bristles to the ferrule.
- the ribs determine univocally the side of the ferrule into which the bundle of bristles is inserted and the side into which the handle is inserted.
- the ferrules are usually fed into the loader of the ferrule-assembly machine manually by a worker who positions them, one at a time, in the loader; this operation takes a long time and entails high production costs.
- One conventional solution provides to use a vibrating feeder which feeds the ferrules, aligned on a belt, one by one; there are means which detect the orientation of the ferrule on the belt and expulsion means which intervene in the event that the ferrule is not correctly oriented, returning it to the feeder.

- the loader Upstream of the entrance to the feeder of the ferrule-assembly machine, the loader according to the invention comprises optical detection means able to recognize the orientation of the ferrules and to identify the ferrules which are not correctly oriented.
- the detection means are associated with pick-up means which are activated in the event that an incorrectly oriented ferrule is identified.
- the pick-up means consist of suction cup means able to pick up the incorrectly oriented ferrules from the conveyor belt and to rotate them through 180° to allow them to be fed correctly to the ferrule-assembly machine.
- the pick-up means are activated for every ferrule, in order to pick up the ferrules from a first feeder belt and to deposit them on a second discharge belt associated with the loader of the ferrule-assembly machine.
- the ferrule If the ferrule is already correctly oriented, it is simply transferred onto the discharge belt; otherwise, it is first rotated by 180° and then deposited on the discharge belt.

Abstract
Description
- The invention concerns an automatic loader of ferrules for brushes, used in the brush production industry to feed correctly oriented ferrules to a ferrule-assembly machine wherein a bundle of bristles and possibly a handle is associated with the ferrules.
- The invention also concerns the relative method to feed ferrules to a ferrule-assembly machine for brushes.
- The invention is applied to brushes of a substantially flat type wherein the ferrule consists of a metal or plastic strip, closed in a ring substantially of any shape: rectangular, round, polygonal, etc.
- In the brush production industry, the state of the art includes ferrule-assembly machines which are fed separately with bundles of bristles, which constitute the end part of the brush, and with ferrules onto which the bundles of bristles are attached, normally glued.
- The ferrules normally consist of metal or plastic strips closed in a ring, the edges overlapping in correspondence with one of the narrow sides so as to constitute a closing ridge.
- The ferrules generally have perimeter ribs and writings or markings to identify the brush, such as the size, brand, type of bristle or other information, which define a univocal assembly position for the bundle of bristles and the handle with respect to the ferrule itself.
- The function of the ribs is both to stiffen the ferrule and as an anchor for the glue used to attach the bristles to the ferrule. The ribs determine univocally the side of the ferrule into which the bundle of bristles is inserted and the side into which the handle is inserted.
- At present, the ferrules are usually fed into the loader of the ferrule-assembly machine manually by a worker who positions them, one at a time, in the loader; this operation takes a long time and entails high production costs.
- One conventional solution provides to use a vibrating feeder which feeds the ferrules, aligned on a belt, one by one; there are means which detect the orientation of the ferrule on the belt and expulsion means which intervene in the event that the ferrule is not correctly oriented, returning it to the feeder.
- Although this solution is very valid in that it makes it much faster to feed the ferrules, compared with the manual method, it is not completely satisfactory since it entails limited productivity in the event that there is a high percentage of incorrectly oriented ferrules among the total of those fed. Moreover, the system is not able to adapt to every type and every size of ferrule, which means it is necessary to make corrections and modifications every time the model is changed; this makes production times longer and increases the costs.
- The present Applicant has devised and embodied this invention to overcome the shortcomings of the state of the art and to obtain further advantages.
- The invention is set forth and characterized in the respective main claims, while the dependent claims describe other characteristics of the main embodiment.
- The purpose of the invention is to provide a completely automatic loader of ferrules for brushes, able to guarantee that the ferrules, correctly positioned and oriented, are fed at high speed to a ferrule-assembly machine.
- Another purpose is to achieve a universal loader suitable to feed ferrules of any type, material, shape and size, varying in width at least from 20 to 100 mm and in height at least from 30 to 50 mm.
- The invention allows to feed both metal ferrules made of brass, copper, stainless steel or other, made from sheet metal closed in a ring, and also ferrules made of plastic material. The invention allows to considerably increase the productivity of the ferrule-assembly machine and there is substantially no need for workers to be present; this consequently reduces the overall costs of making up the brushes.
- Moreover, the loader is simple to make, economical and is very limited in bulk and energy consumption.
- The invention is applied in cooperation with usual feeder assemblies, whether they be of the vibration type or not; only simple, quick and inexpensive modifications are required.
- The automatic loader according to the invention has a guide channel associated with a conveyor belt, which is connected to a container/feeder from which the ferrules are fed, separate and one by one, with one wide face resting on the plane of the belt.
- Upstream of the entrance to the feeder of the ferrule-assembly machine, the loader according to the invention comprises optical detection means able to recognize the orientation of the ferrules and to identify the ferrules which are not correctly oriented.
- The detection means are associated with pick-up means which are activated in the event that an incorrectly oriented ferrule is identified.
- In a preferential embodiment, the pick-up means consist of suction cup means able to pick up the incorrectly oriented ferrules from the conveyor belt and to rotate them through 180° to allow them to be fed correctly to the ferrule-assembly machine. In another preferential embodiment, the pick-up means are activated for every ferrule, in order to pick up the ferrules from a first feeder belt and to deposit them on a second discharge belt associated with the loader of the ferrule-assembly machine.
- If the ferrule is already correctly oriented, it is simply transferred onto the discharge belt; otherwise, it is first rotated by 180° and then deposited on the discharge belt.
- In this embodiment, every time a ferrule reaches a set position with respect to the optical detection means, the conveyor belt stops, until the cycle to pick up and discharge the ferrule is complete.
- This embodiment allows to make the loading times of the ferrules independent of the working times of the ferrule-assembly machine, preventing problems in the event that blockages or downtimes of the machine occur during the steps of inserting the bristles or the handle into the ferrules.
- In the event that the conveyor belt is full of ferrules, sensor means intervene to stop the vibrating feeder.
- In the event that the ferrule is positioned upside down on the conveyor belt, for example with the markings not visible, the optical detection means recognize this condition and activate discharge means able to pick up the ferrule and return it to the feeder.
- The functioning of the loader according to the invention is governed by the commands of a control unit equipped with memory means which contain sample images related to a plurality of types of ferrule which can be used with the loader.
- At the start of the cycle, an operator selects the type of ferrule being worked, so that the optical detection means are able to compare the ferrules advancing on the conveyor belt with the sample image selected, and to recognize conditions of correct or incorrect orientation.

- The
reference number 10 denotes generally an automatic loader offerrules 11 which is applied in makingbrushes 12 of a substantially flat type comprising aferrule 11 to which a bundle ofbrushes 13 is solidly associated on one side and ahandle 14 on the other. - The
ferrule 11, in the case shown here, is of the type made from a strip of metal sheet closed in a ring with the edges overlapping along one of the narrow sides so as to constitute aclosing ridge 15, which, in this case, has arounded side 16 and a protruding fold 17 (Fig. 2). - The
ferrule 11 has aperimeter rib 18a associated with the edge cooperating with thehandle 14, and twoperimeter ribs 18b associated with the edge cooperating with the bundle ofbristles 13. - The ferrules (Figs. 3 and 4a-4c) also have identification markings, in this case a number (75 in Fig. 3 and 60 in Figs. 4a-4c) which indicates the measurement of the
brush 12; in cooperation with theribs bristles 13 and handle 14 with respect to theferrule 11. - The
automatic loader 10 comprises a feeder-vibrator assembly 19 equipped with abasket 20 to thelateral wall 21 of which aguide channel 23 is associated; theferrules 11 aligned one by one pass on theguide channel 23 to be fed to afirst conveyor belt 30. - The
first conveyor belt 30 is equipped with lateral guides 130 (Fig. 3) adjustable at least in width according to the width of theferrules 11 to be loaded; the function of theguides 130 is to align theferrules 11 with one wide face resting on thebelt 30. Theferrules 11 are loaded pell-mell into thebasket 20 and, due to the vibration, are separated and aligned on the plane of theconveyor belt 30. - In cooperation with the terminal zone of the
first conveyor belt 30, theloader 10 according to the invention has optical detection means 29 to detect the orientation of theferrules 11; the optical detection means 29 are functionally associated with acontrol unit 31, shown for the sake of simplicity in Fig. 4a only. - The function of the optical detection means, in this case a
video camera 29, is to verify that theferrule 11 which is about to be sent to the discharge zone is correctly oriented for coupling withbristles 13 and handle 14. - The detection operation is based on the numerical marking located on one side of the
ferrule 11. - To perform the detection operation, the invention provides that sensor means 32 interrupt the advance of the
first belt 30 in correspondence with an end-of-travel position, aligning thefirst ferrule 11 to the lens of thevideo camera 29. - The image taken by the
video camera 29 is sent to thecontrol unit 31 which, by means of aprocessing unit 33, compares it with a sample image memorized in anappropriate memory cell 34 and selected by an operator, who makes the setting at the beginning of the cycle, by means of akeyboard 35 or similar means. - The
control unit 31 can detect three possible cases. In a first case (Fig. 4a) theferrule 11a is correctly oriented. - In this case, the
control unit 31 commands a first suction cup means 24 (Fig. 5) to be activated, which is able to be lowered to pick up theferrule 11a from the terminal end of the first conveyor belt 30 (position 24a), and to move forwards in adirection 36 to deposit theferrule 11a on the initial end of a second discharge belt 25 (position 24b). - In correspondence with the terminal end of the
second discharge belt 25 there is a second suction cup means 26 able to pick up the correctly orientedferrule 11a and deposit it in anassembly zone 27, where theferrule 11 is coupled, in a substantially conventional manner, withbristles 13 and handle 14. - In a second case, wherein a
ferrule 11b is not correctly oriented (Fig. 4b), thevideo camera 29 recognizes the numerical marking but identifies that it is incorrectly oriented. - In this case, the first suction cup means 24 is able to rotate through 180°, in a direction indicated by the
reference number 37, around its substantially vertical axis in order to restore the correct orientation of theferrule 11b. To be more exact, the first suction cup means 24 is lowered to pick up theferrule 11b from thefirst conveyor belt 30, then is raised, rotates on itself by 180° and then moves forwards; it then discharges the correctly orientedferrule 11b onto thesecond discharge belt 25, which provides to carry it to theassembly station 27. - In the third case, shown in Fig. 4c, the
video camera 29 recognizes a situation in which the numerical marking is not visible and where therefore the orientation of theferrule 11c cannot be corrected simply with the help of the first suction cup means 24. - In this case, the invention provides to activate a third suction cup means 22 able to pick up the
ferrule 11c from thefirst conveyor belt 30 and to deposit it on athird recovery belt 28, which has a direction of feed opposite to that of thebelts basket 20. - In this way, with the method according to the invention, only the
ferrules 11c, which are in a position which cannot be corrected by means of the first suction cup means 24, are returned to the vibratingfeeder 19, whereas all the other ferrules are fed forwards substantially continuously and discharged by means of thesecond discharge belt 25. - By using suction cup means 24, 26 and 22, the position of which can be adjusted both longitudinally, transversely and vertically with respect to the relative conveyor belts, it is possible to adapt the
loader 10 to any size, shape and type of ferrule without needing important modifications and adaptations. - Modifications and variants may be made to the invention without departing from the spirit and scope thereof. For example, an alternative embodiment provides that the suction cup means itself transfers both the correctly oriented ferrules, or after the rotation, to the
discharge belt 25, and also the upside down ferrules to therecovery belt 28. In another embodiment, the suction cup means can be replaced by magnet means, in the case of metal ferrules, or by gripper means. In another embodiment, theconveyor belt 30 can have a continuous feed, instead of a discontinuous one as described.
