Description

Technical Field

[0001] The present invention relates to a machine for manufacturing brush-type tools for household and / or industrial use, particularly tools such as brushes, brooms, etc., wherein the bristle bundles are fixed to the body of the tool by locking elements or anchoring elements. Background Technology

[0002] According to existing technology, bristle bundles or tufts are fixed to the body or base of a bristle-type tool, such as a brush or broom, by performing a drilling operation and a subsequent stamping operation. During the drilling process, a cavity or blind hole is formed in the tool body, typically made of plastic material. During the subsequent stamping operation, the bristle bundle is inserted into the cavity or blind hole and fixed therein by a corresponding locking or anchoring element. More precisely, each bristle bundle is grouped and folded into a "U" shape around a corresponding anchoring element to form an anchoring end, which, together with the anchoring element, is inserted by a punch into a corresponding hole in the tool body.

[0003] Known machines for manufacturing brush-type tools include conveying devices or processing systems equipped with multiple carrier units, each carrier unit being configured to house and support one or more bodies or bases of the tool, and capable of moving along a closed-loop path to sequentially move the body through various operating stations of the machine to undergo different processing operations.

[0004] Specifically, the operating stations include the supply station, drilling station, stamping station, and take-out station.

[0005] In the supply station, the tool body is transferred manually by the operator or automatically by a dedicated supply system and housed in the carrier unit.

[0006] In the drilling station, one or more drilling tools form holes in the tool body for the bristle bundle. In the stamping station, one or more punches insert the anchoring end of the bristle bundle, along with the corresponding anchoring element of the bristle bundle, into the holes in the tool body.

[0007] At the removal station, the bristle-equipped tool is removed from the carrier unit either manually by the operator or automatically by a dedicated gripping and removal system.

[0008] Anchoring elements are typically in the form of hooks or plates and are made of metal. The lateral dimension of the anchoring element is larger than the lateral dimension of the cross-section of the hole, which is usually cylindrical. During the stamping process, the anchoring element is wedged in like a nail and firmly embedded in the plastic material of the tool body, causing the tool body to deform. The anchoring element embedded in the hole ensures stable tensile strength or resists the resistance of the bristle bundles being removed from the tool body.

[0009] Therefore, the use of metal anchoring elements ensures a firm and stable fastening of the bristles, but raises questions about the recyclability of the tool itself, as the tool consists of plastic parts (body and bristle bundles) and metal parts (anchoring elements), which cannot be disposed of together.

[0010] In order to properly handle and recycle brush tools, the metal components must be removed and processed separately, which makes the entire recycling process of the tools complex and costly.

[0011] To solve this problem, anchoring elements made of plastic material are used to secure the bristle bundles to the holes in the body.

[0012] However, anchoring elements made of plastic cannot be embedded into the plastic material of the tool body by cutting or deforming the material; they can only be deformed by being forced into the hole. The deformation of the anchoring element—particularly the deformation of the opposite end of the anchoring element that contacts the columnar inner wall of the hole—is insufficient to achieve a connection that ensures strong, stable, and, in particular, durable tensile retention of the bristle bundle with time and use.

[0013] For this purpose, in order to securely and permanently lock the anchoring element in the hole after insertion, known machines include means for melting the contact area between the anchoring element and the inner wall of the hole in a stamping station or a dedicated operating station located downstream of the stamping station.

[0014] However, these gluing and welding devices and / or operating stations make the machines used to produce the tool significantly more complex and expensive. Summary of the Invention

[0015] The object of the present invention is to improve known machines for manufacturing brush-type tools for household and / or industrial use, in particular, in which the bristle bundles are secured to the tool body by locking or anchoring elements made of plastic material.

[0016] Another objective is to provide a machine that allows the bristle bundles to be effectively, stably, and permanently locked to the body or base of the tool using anchoring or locking elements made of plastic material similar to the body.

[0017] Another objective is to provide a machine for manufacturing brush-like tools that are entirely made of plastic and therefore fully recyclable.

[0018] The above and other objectives are achieved by a machine for manufacturing brush-type tools according to one or more of the following claims. Attached Figure Description

Detailed Implementation

[0020] Reference Figures 1 to 10 The invention illustrates a machine 1 for manufacturing household and / or industrial bristle-type tools 50, such as brushes, brooms, etc. Each bristle-type tool 50 includes a body 51 made of plastic material, the body 51 being provided with a plurality of open cavities 52 adapted to receive corresponding bristle bundles 60 made of plastic material, the bristle bundles 60 being locked in the cavity 52 by means of anchoring elements 61 also made of plastic material and partially deformable.

[0021] The machine 1 of the present invention includes a plurality of support units 2, which are movable along a closed-loop movement path P, which is, for example, circular, and the support units are configured to accommodate and support the body 51 of at least one corresponding bristle tool 50.

[0022] Machine 1 also includes a drilling station 3 and a stamping station 5. The drilling station 3 is equipped with a drilling device 4 to form a plurality of open cavities 52 on each body 51, such as blind column holes. The stamping station 5 is equipped with a stamping device 6, which is adapted to force the corresponding bristle bundles 60 and the corresponding anchoring elements 61 into the cavities 52.

[0023] Specifically, the drilling device 4 forms a cavity or hole 52 by interacting with the outer surface 54 of the body 51, which includes a flat surface, a curved surface, or a plurality of adjacent and non-coplanar surfaces.

[0024] Each cavity 52 extends inside the body 51 along direction X, which is perpendicular to or inclined relative to the outer surface 54.

[0025] Machine 1 is also provided with a guide device 7, which is used to slidably support the carrier unit 2, which is capable of moving along the movement path P through the drilling station 3 and the stamping station 5, and in particular moving in a predetermined forward direction A (see reference). Figure 1 The floor plan is in a clockwise direction.

[0026] The support unit 2 includes a corresponding clamping device 12, which is of a known type and therefore not described or shown in detail, which is adapted to support and fix the body 51 of the brush tool 50 as it moves through the drilling station 3 and the stamping station 5.

[0027] The guiding device 7 includes, for example, an annular guide, on which a movable support unit is slidably mounted, for example, by a corresponding actuator.

[0028] Alternatively, the carrying unit 2 can be driven by a moving belt or chain associated with the guiding device 7.

[0029] The drilling apparatus 4 includes at least one drilling tool 14 of a known type, which is mounted on a drilling head 13 at the drilling station 3. The drilling head 13 is capable of moving linearly along the drilling direction C to sequentially form cavities or holes 52 on each body 51.

[0030] The stamping device 6 includes at least one stamping tool 16 of a known type, which is mounted on a stamping head 15 of the stamping station 5. The stamping head 15 is linearly movable along the operating stamping direction D to force the bristle bundle 60 and its corresponding anchoring element 61 into the corresponding cavity 52 of the body 51. For this purpose, the stamping station 5 includes a bristle supply device 25 and a pick-up device 26 configured to pick up the bristle bundle 60 from the supply device 25. Both the bristle supply device and the pick-up device are of a known type and will not be described in detail. The pick-up device 26 conveys the bristle bundle 60 to an insertion device 27, which is also of a known type and will not be described in detail. The insertion device 27, together with the anchoring element 61, is loaded onto the stamping tool 16. Specifically, the insertion device 27 transfers the bristle bundle 60 to the stamping tool 16, which is grouped and folded into a U-shape around its corresponding anchoring element 61 to form the anchoring end 60a to be inserted into the cavity 52.

[0031] The machine 1 also includes a grooving device 8, which is adapted to form at least one notch or groove 55 on the sidewall 53 of each cavity 52 in the body 51, the notch or groove extending inside the body 51, and in particular, the notch or groove narrowing toward the interior of the body and having an opening 55a to allow the corresponding anchoring element 61 to be inserted and locked by interference and partial deformation.

[0032] The grooving device 8 can be associated with the grooving station 9 located between the drilling station 3 and the stamping station 5, or the grooving device 8 can be associated with either the drilling station 3 or the stamping station 5.

[0033] exist Figures 1 to 10In the illustrated embodiment, the machine 1 includes a grooving station 9 positioned between the drilling station 3 and the stamping station 5, and the grooving device 8 includes at least one grooving tool 18 mounted on a grooving head 19 of the grooving station 9, the grooving head 19 being capable of linearly moving along the grooving direction B to form a groove 55 in each cavity 52 of the body 51.

[0034] In the illustrated embodiment, the slotting device 8 is configured to form a pair of notches or grooves 55 on the particularly columnar sidewalls 53 of each cavity 52, the pair of notches or grooves facing each other and opposite each other, each groove 55 extending inside the body 51, particularly narrowing towards the interior of the body 51, and provided with an opening 55a for inserting the anchoring element 61.

[0035] Specifically, each groove 55 has a generally constant and rectangular cross-section, which is substantially orthogonal to the sidewall 52 of the cavity. It is also conceivable that the cross-section of the groove 55 may narrow towards the interior of the cavity 52. ​​In particular, the two facing and opposing walls of the groove 55 and / or the wall connecting these two walls may narrow towards the interior of the cavity.

[0036] In particular, such as Figures 6 to 10 In the embodiment illustrated herein, the grooving device 8 may also be configured to form a groove 55, which includes a corresponding first inlet portion 55b and a corresponding second anchoring portion 55c. The first inlet portion 55b is provided with an opening 55a, and the second anchoring portion 55c has a smaller size than the first inlet portion 55b and is provided with an anchoring wall suitable for engaging with the anchoring element 61, as further explained in the specification.

[0037] In this case, the cross-section of the first inlet portion 55b and the second anchoring portion 55c of each groove 55 is also approximately constant and rectangular in shape.

[0038] Machine 1 also includes a supply station 10 and a removal station 11. The supply station 10 is positioned upstream of the drilling station 3 with reference to the forward direction A of the support unit 2, in which the body 51 of the brush tool 50 is inserted into the support unit 2. The removal station 11 is positioned downstream of the stamping station 5 with reference to the forward direction A, in which the brush tool 50 is removed from the support unit 2.

[0039] In the embodiment of the machine 1 of the present invention illustrated in the accompanying drawings, the supply station 10 and the take-out station 11 coincide.

[0040] More precisely, operator W manually removes the completed brush tool 50, i.e., the tool with a body 51 having a cavity 52 into which the bristle bundle 60 has been inserted and secured by the anchoring element 61, from the clamping device 12 of the support unit 2. Then operator W manually loads the body 51 with the bristle bundle 60 to be installed onto the clamping device 12 of the support unit 12.

[0041] Alternatively, instead of an operator, machine 1 may be equipped with appropriate removal and loading devices for removing the completed bristle tool 50 from the carrier unit 2 and loading the body 51 of the bristle bundle to be installed onto the carrier unit 2.

[0042] The operation of the machine 1 for manufacturing brush-type tools according to the present invention involves loading the body 51 of the tool 50 onto the carrier unit 2 at the supply station 10 and the take-out station 11, each carrier unit 2 moving autonomously and independently along the movement path P.

[0043] Each support unit 2 stops at the drilling station 3, where the drilling device 4 forms the required multiple cavities or holes 52 on the body 51. Figures 2 to 4 ).

[0044] After drilling is completed, the bearing unit 2 moves to the subsequent grooving station 9, where the grooving device 8 forms, for example, a pair of grooves 55 facing each other and opposite each other on the sidewall 53 of each cavity 52 of the body 51. The grooves 55 extend inside the body 2 and are provided with corresponding openings 55a. The openings 55a open on the outer surface 54 of the body 51 to allow the insertion of the anchoring element 61. Figures 5 to 7 ).

[0045] After the grooving operation is completed, the bearing unit 2 moves to the subsequent stamping station 5, where the stamping tool 16 of the stamping device 6 inserts the bristle bundle 60 and the corresponding anchoring element 61 into each cavity 52 previously formed on the body 51. Specifically, the stamping tool 16 forcibly inserts the insertion end 60a of the bristle bundle 60 together with the corresponding anchoring element 61 into the corresponding cavity 52. ​​In this way, the anchoring element 61 interferes with the anchoring wall of the second portion 55c of the engagement groove 55. More precisely, the anchoring element 61 is pushed into the second anchoring portion 55c by the stamping tool 16 along the stamping direction D, causing the anchoring element 61 to deform against the anchoring wall. Figures 8 to 10 ).

[0046] The deformation of the plastic material of the anchoring element 61 and the friction between it and the anchoring wall of the groove 55 ensure significant tensile strength of the bristle bundle 60. It should be noted that the opposing ends of the anchoring element 61 engage all three anchoring walls of each groove 55, which increases the contact area and thus increases the friction between the anchoring element 61 and the cavity 52, significantly enhancing the tensile or removal resistance of the anchoring element 61, and consequently enhancing the tensile or removal resistance of the bristle bundle 60 associated with the anchoring element 61.

[0047] Tests conducted by the applicant show that, in tools manufactured using the machine 1 of the present invention, the stretching or removal resistance exhibited by the bristle bundles 60 fixed in the cavity 52 of the body 51 by the corresponding anchoring element 61 made of plastic material is comparable to the stretching or removal resistance of the bristle bundles in tools having the same body (in terms of material and size) but provided with metal anchoring elements.

[0048] Because of the machine 1 of the present invention, brush-type tools for household and / or industrial use can be produced, wherein the bristle bundles are firmly, stably and permanently attached to the tool body using anchoring elements made of the same plastic material as the tool body and the bristles, and since the anchoring elements are made entirely of plastic material, they can be fully recycled.

[0049] Reference Figures 11 to 13 This illustrates a variation of machine 1 of the present invention, which is similar to... Figures 1 to 10 The difference between the embodiments described and shown is that the grooving station 9, located between the drilling station 3 and the stamping station 5, is not included because the grooving device 8 is associated with the drilling station 3. More precisely, the grooving device 8 includes at least one grooving tool 28 associated with the drilling tool 14 of the drilling device 4. Both the drilling tool 14 and the grooving tool 28 are mounted on the drill head 23 of the drilling station 3, which is linearly movable along the drilling direction C to form a cavity 52 and one or more grooves 55 on each body 51 of the tool 50.

[0050] Specifically, the grooving tool 28 is coaxially mounted on and around the drilling tool 14, and the grooving tool 28 is integrally connected to the drilling tool 14 to move linearly along the drilling direction C. The drilling tool 14 is of a known type and is also capable of rotating about a longitudinal axis parallel to the drilling direction C.

[0051] It is also envisioned that the grooving tool 28 can move independently and autonomously relative to the drilling tool 14 along the drilling direction C.

[0052] Specifically, the grooving tool 28 includes a hollow body 28a coaxially mounted on the drilling tool 14, to which one or two grooving blades 28b are attached (in the illustrated embodiment, two opposite blades) to form a corresponding groove 55 in a cavity 52 made by the drilling tool 52.

[0053] The operation of this variant of machine 1 of the present invention and Figure 1 The only difference in the operation of the machine in this embodiment is that the drilling and grooving operations are performed almost simultaneously or rapidly and continuously within the same drilling station 3. Specifically, when the body 51 of the tool 50, which is moved by the corresponding support unit 2, is available at the drilling station 3, the drill head 23 moves toward the body 51 along the drilling direction C. The appropriately rotated drilling tool 14 contacts the outer surface 54 of the body 51 and drills a hole, thus forming a cavity 52. ​​At the same time, the grooving tool 28, which is integrally connected to the drilling tool 14 so that it moves slightly behind the drilling tool 14 along the drilling direction C, also abuts against the outer surface 54 of the body 52. ​​The central portion of the grooving tool 28 is inserted into the cavity 52, and the opposite outer portion of the grooving tool 28 forms two grooves 55 on the side wall 53 of the cavity 52.

[0054] The grooving tool 28 can also be moved linearly relative to the drilling tool 16 to adjust the operation of the grooving tool 28 on the body 51, for example, to form a groove 55 after the hole 52 is completed and the drilling tool 14 has disengaged from the hole 52.

[0055] Reference Figures 14 to 16 This illustrates a variation of the machine 1 of the present invention, which is similar to... Figures 1 to 13 The difference between the embodiments described and shown is that the grooving station 9, which is located between the drilling station 3 and the stamping station 5, is not included, because the grooving device 8 is associated with the stamping station 5.

[0056] More precisely, the grooving device 8 includes at least one combined grooving and stamping tool 38, which also serves as a stamping tool for the stamping device 6.

[0057] The grooving and stamping tool 38 is mounted on the stamping head 15 of the stamping station 5. The stamping head 15 is capable of moving linearly along the operating stamping direction D to form one or two grooves 55 on each cavity 52 of each body 51. Then, the bristle bundle 60 is inserted into the cavity 52, and the corresponding anchoring element 61 is inserted into the cavity 52 and the groove 55.

[0058] For this purpose, the grooving and stamping tool 38 includes, for example, an inner portion 38a and an outer portion 38b, the inner portion 38a being adapted to receive the operating ends of the bristle bundles 60 and their corresponding anchoring elements 61, and the outer portion 38b being provided with one or two operating accessories (in the illustrated embodiment, two opposing blades) capable of forming corresponding grooves 55. The bristle bundles 60, grouped and folded into a U-shape around their respective anchoring elements 61 to form the anchoring ends 60a of these bundles, are transferred and loaded onto the grooving and stamping tool 38 by an insertion device 27, which receives the bristle bundles 60 and the anchoring elements 61 from the first supply device 25 and the second supply device 26 of the stamping station 5, respectively.

[0059] The operation of this variant of machine 1 of the present invention and Figure 1 The only difference in the operation of the machine in this embodiment is that the drilling and stamping operations are performed almost simultaneously or rapidly and continuously within the same stamping station 5 by a single grooving and stamping tool 38. Specifically, when the body 51 of the tool 50, moved by the corresponding support unit 2, is available at the stamping station 5, the stamping head 15 moves toward the body 51 along the operating stamping direction D. The appropriately actuated combined grooving and stamping tool 38 contacts the outer surface 54 of the body 51, specifically inserting the central portion of the grooving and stamping tool into the cavity 52, and forming two grooves 55 on the sidewall 53 of the cavity 52 by two opposing operating attachments of the outer portion of the grooving and stamping tool 38. Simultaneously, the combined grooving and stamping tool 38 inserts the anchoring end 60a of the bristle bundle 60 with its corresponding anchoring element 61 into the thus formed groove 55.
