Description

Technical Field

[0001] The present invention relates in particular to industries involving the coating of parts, for example industries that cover parts such as profiles, fins, panels, boards, etc. with a tape-shaped or strip-shaped coating material such as a flat plate, a protective sheet or a decorative sheet. More specifically, the present invention relates to a system for readjusting a tool support part and / or replacing a tool for attaching a coating material to new parts of different shapes placed in a part coating machine.

Background Art

[0002] Component coating machines are known that are used to coat profiles for mainly decorative applications, such as furniture, door profiles, windows, etc., in response to the surface finishing process of components typically made of wood or its derivatives, aluminum, PVC, etc. In this type of machine, the components are conveyed longitudinally by a conveyor along a conveyor path, and thereby coated with a continuous or discontinuous sheet made of different materials such as paper, PVC, CPL, etc. using an adhesive. Thereby, the components are given any desired appearance and it is also possible to achieve any properties based on the type and design of the coating material used.

[0003] In these machines, there are a plurality of support parts along the conveyor path of the components, where tools, preferably in the form of replaceable pressure rollers, are supported. After applying an adhesive to the coating sheet and / or the component and then placing the coating sheet on the upper surface of the component, the component already provided with the sheet passes through the roller, whereby the sheet is extended to cover its outer shape by the pressure roller. At each tool position, the surface of the formed roller is made to coincide with the corresponding surface portion of the component, and the position and inclination of the axis of the pressure roller need to be adjusted according to the outer shape to be processed in order to process the coating material to fit accurately and step by step to the component shape.

[0004] Therefore, when changing the covering to a different component, in addition to readjusting the support to set the new position, it is usually necessary to replace the pressure roller with one having a different outer shape or hardness.

[0005] Generally, this reconfiguration requires the replacement and adjustment of numerous pressure rollers by adjusting the support structure, which is time-consuming and involves a long period of downtime, resulting in high costs. Furthermore, this reconfiguration requires the expertise and experience of workers who are well-versed in methods for achieving proper coverage.

[0006] An existing solution to this problem and reduce reconfiguration time is proposed in Patent Document 1, which discloses an apparatus for modifying an outer shape coating machine, which provides the operator with a static magazine that provides a screw conveyor or holding robot for corresponding rollers, so that the rollers can be replaced according to the new outer shape to be placed in the machine. Furthermore, the apparatus includes a program that algorithmically selects the corresponding pressure rollers and their locations based on the shape of a given outer shape that can be input as CAD data. This reduces readjustment time by allowing the operator to position the tools accordingly. Furthermore, the apparatus includes a signaling device that indicates the roller placement location to the operator, and a data processing system that determines the necessary adjustments to multiple support parts and explains to the operator how to adjust the support parts.

[0007] However, this system still requires human intervention, which can delay processing and potentially lead to adjustment errors during reconfiguration if the operator is inexperienced. Furthermore, situations arise where adjustments that can only be made by experienced operators are not considered by the system's reconfiguration decision software, resulting in defective parts that increase production costs. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Spanish Patent No. 2527574 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] Considering the aforementioned shortcomings and limitations of existing solutions, and given that the current configuration of this type of machine is entirely manual when inserting new parts of different shapes, there is a need for a solution that enables the automation of the coating machine changeover process in an economically feasible manner, minimizing downtime due to reconfiguration, providing the versatility to be readjusted and processed by experienced operators, and reducing defective products. [Means for solving the problem]

[0010] To achieve this objective, solve the technical problems described herein, and provide the additional advantages that will become apparent below, the present invention provides a part covering system comprising a conveyor for transporting a part to be covered longitudinally. The longitudinal direction is understood to be the same direction and viewpoint in which the covering material is first applied to the part. The part covering system comprises a plurality of non-motorized position supports, each having at least one pressurizing tool, which presses the covering material onto the part when the part to be covered is transported according to a predetermined orientation of the pressurizing tool based on the shape of the part. The system comprises a memory having a correspondence between the shape of the part, the type of tool, and the positioning of each position support with respect to the orientation of the tool, and a control means that determines the positioning of each position support for reconfiguration, taking into account the position database in the memory when parts to be covered of different shapes are placed. The part covering system comprises at least one motorized actuator, which can be connected to a plurality of position supports and is configured to connect to a corresponding position support, release the position support, and perform operations for reconfiguration of the position supports based on commands given by the control means according to the shape of the part to be covered.

[0011] "Release" is understood to mean unlocking the movement of the support so that it can be adjusted by applying force, but not completely unlocking it, thereby allowing it to be operated by that adjustment movement.

[0012] Preferably, the release is performed selectively; that is, the lock on the movement of the support is released based on the need for adjustment.

[0013] Unlike other embodiments that use robotic positioning supports for tools, which result in higher manufacturing and maintenance costs compared to conventional systems, this electric actuator enables automation that reduces the time required to reconfigure multiple positioning supports when the shape of the parts or profile material placed in the coating system changes, while suppressing cost increases. Given a database containing the correspondence between part shapes, support locations and orientations, and / or the tools being changed, stored in the system's memory, the control means determines reconfiguration parameters and transmits relevant commands so that the electric actuator reconfigures the multiple supports based on the shape of the newly introduced part.

[0014] This automation is made possible by configuring the electric actuator to receive commands from a control means, and further by configuring it to change its position by coupling to and releasing a corresponding support, after which the support is re-restrained and the electric actuator is released. In accordance with the positioning command, the electric actuator acts on the required number of support units, safely and efficiently reconfiguring the molding line composed of position support units.

[0015] This eliminates the need for human intervention and reduces errors in timing and positioning. Furthermore, it can be easily applied to existing coating machine models on the market.

[0016] Regarding release, the position support unit may be equipped with release means, such as an electric brake or a hydraulic means. Therefore, preferably, the function of these release means is to lock the movement of the position support unit, but they are configured to be activated by an electric actuator in accordance with a command from the control means and / or by receiving a release signal issued from the control means for the purpose of release.

[0017] According to the features of the present invention, the electric actuator can be moved to each position support in accordance with a command from a control means for reconfiguring its posture and / or changing its location.

[0018] The actuator is movable, preferably by guide, which facilitates the identification of the support points and allows the electric actuator to precisely move to each support point, engage with it, and act upon release. This electric actuator can be in the form of a robot with a limited range of motion to avoid the risk of accidents, or in the form of a collaborative robot that avoids the risk of accidents caused by human traffic by operating in a safety mode. Furthermore, as described above, the electric actuator can move along guides, thereby limiting the range of motion. All of these features enable workers to safely perform maintenance and adjustment tasks.

[0019] According to another embodiment of the present invention, the electric actuator is in the form of a movable device and comprises a support positioning means and a corresponding actuation means for reconfiguring the attitude according to a command from a control means. Thus, the electric actuator, in this case the movable device, moves to the corresponding support in accordance with a command received from the control means, automatically couples with it, and when the actuation means is connected to the support positioning means and thereby actuated, the support is positioned according to a tool position determined for that part.

[0020] Preferably, the movable device is in the form of a cart with three individually motorized axes, and is configured to be coupled to a positioning element corresponding to each positioning axis of the position support.

[0021] According to another embodiment of the present invention, the electric actuator is not movable and is fixed to the reconfiguration area, receives the position support parts and couples to them, and performs an operation to change its posture. In this case, a further cooperating worker or robot is responsible for removing the corresponding support part from the coating machine and bringing it to the electric actuator in the reconfiguration area. The electric actuator knows the position of the support part within the machine and changes its posture based on the command indicated from the control means.

[0022] With this configuration, during the reconfiguration of the support part, an operator or robot can perform other operations, and the reconfiguration time is shortened.

[0023] According to one aspect of the present invention, in addition to changing the location and posture of the support part, the electric actuator is configured to remove a tool from the support part and replace it with another one from the tool magazine according to a command from the control means.

[0024] In addition to the operation of the electric actuator, the coating system of the present invention enables an operator to perform adjustment work in manual mode after the electric actuator and / or the control system releases the support part. For this purpose, the system of the present invention includes auditory and / or display means for indicating the changes made for the positioning reconfiguration and / or tool replacement of each support part based on a command from the control means. Thereby, the reconfiguration time is shortened and manual work is possible even when there is some defect in the electric actuator, for example.

[0025] With this configuration, as another embodiment of the movable device in cart form, based on a command from the control means, the device can be moved by the work of an operator who moves to the corresponding support part and couples it. Further, the operating means is in the form of a manual drill that can be operated by an operator, and it is conceivable that the operator connects to the position positioning means and acts on each axis according to a command given through the auditory and / or display means by the control means.

[0026] According to another aspect of the present invention, the control means is configured to record in a memory a manual position adjustment of the position support part by an experienced operator, and then process it in a future reconfiguration including parts of the same shape. This enables so-called "master touch (first-class skill)", that is, adjustment of the support part position based on the operator's experience. With this configuration, it can be automated without an operator thereafter, so that the adjustment can be shown to an operator who does not have the knowledge of accurate positioning by himself / herself after the adjustment or after the system processes it. As a result, defects are reduced and waste of materials is avoided.

[0027] The manual adjustment can be carried out by an experienced operator directly on the support part or by having a system of a manual control device that can control an electric actuator such as a push button. Thereby, the adjustment is recorded according to the operation instructed to the electric actuator by the push button.

[0028] [[ID=⑧]] According to another embodiment, when the operator makes an adjustment with the actuator not coupled, or when the system cannot record the movement of the coupled actuator, the support part is configured to detect position adjustments made in each degree of freedom of the position support part, such as using an encoder that communicates with the control means to record and process the adjustment.

[Figure 4]This is a side view of the system of the present invention, in which the electric actuator is located on the moving guide and is shown in an uncoupled position. [Figure 5] This diagram is similar to Figure 4, showing the electric actuator coupled to the position support section. [Figure 6] A schematic side view is shown of an electric actuator in the form of a movable device, which includes a positioning means for a position support and a corresponding actuation means. [Figure 7] A schematic front view of a practical embodiment in which an electric actuator is fixedly positioned in the reconfiguration area is shown. [Modes for carrying out the invention]

[0030] Referring to the drawings above and according to the reference numerals, preferred embodiments of the present invention can be seen therein, which include parts and components shown and described in detail below.

[0031] Figure 1 shows a component coating system that is the subject of the present invention, which comprises a coating machine and a plurality of position support units (3) arranged along a conveyor (2) on the bed of the coating machine, which together form a conveyor path on which the component (1) is coated.

[0032] In this conveyor path, the part or profile material (1) is transported on the conveyor (2) in the direction indicated by the arrow (leftward).

[0033] In this case, the covering material (5) is drawn out from the reel (13) as is conventionally done in continuous application. At the application section (12), adhesive is applied to the material for later application to the part (1) moving on the conveyor (2).

[0034] Multiple position support sections (3) collectively form a row of support sections, and the configuration of their orientation, location, and the tools (4) they support are determined by a database stored in the coating machine's memory, depending on the parts (1) placed in the machine.

[0035] The tools (4) placed on each support are preferably in the shape of a pressing roller and have an outer surface configuration corresponding to the part (1).

[0036] Therefore, as the part (1) moves forward on the conveyor (2), the tool (4) is supported by position support parts (3) arranged along the conveyor path, and the covering material on the outer surface of the part (1) is gradually extended from the center outward to conform to its shape.

[0037] However, the introduction of new covered parts of a different shape requires adjustments based on reconstruction parameters, including adjustment of the position support (3), and / or relocation of the support (3), and / or replacement of the tool (4).

[0038] According to the present invention, as shown in Figure 1, the system of the present invention comprises a robot-shaped electric actuator (6), which is preferably a collaborative robot movable to each position support (3), and more preferably movable longitudinally along a guide (6.1) in the transport direction of the part (1). The electric actuator (6) receives commands from a control means (14). The control means (14) determines reconfiguration parameters based on the shape of the new part (1) and indicates to the electric actuator (6) which position support (3) it should act on. Information about the correspondence for reconfiguration is stored in the memory of the covering system, which is accessed by the control means (14) that calculates and determines the reconfiguration parameters.

[0039] Considering the above, the electric actuator (6) can operate to change the orientation of the tool (4) by changing the posture of the position support (3), and / or change the posture of the position support (3) to a new posture that is more suitable for the new shape, and / or take a new tool (4) from the tool magazine (11), replace the previous tool, and return the previous tool (4) to the corresponding position in the magazine (11).

[0040] As shown in Figure 2, the conventional position support (3') for positioning the tool (4) is movable in order to fix it along the Z-axis corresponding to the vertical direction. It is also movable along the X-axis direction and rotatable about the X-axis for precise positioning of the tool. Furthermore, it is movable along the Y-axis direction and rotatable about the Y-axis. These degrees of freedom are controlled by the position support (3) of the present invention, schematically shown in Figure 4.

[0041] Figure 4 shows the electric actuator (6), which is movable longitudinally along the guide (6.1), before coupling to the support (3) as instructed by the control means (14). As shown in Figure 5, when the electric actuator (6) is aligned with the position of the support (3) to be reconfigured, the electric actuator (6) couples with the support (3). Once coupled, the electric actuator (6) disengages from the support (3) so that the support (3) can be positioned according to commands from the control means (14).

[0042] Preferably, each position support (3) is provided with a release mechanism, such as a mechanical release mechanism or an actuation mechanism controlled electromagnetically, pneumatically, or hydraulically. The release mechanism has the function of locking the position support (3) in the working position, and to release it, for example, an electric actuator (6) mechanically connects to the support (3) using a clutch and releases the electromagnetic brake to make the support (3) reconfigurable. Once reconfigured, the release mechanism relocks the support (3) in the newly defined position. The electric actuator (6) can change the tool (4) using a similar clutch.

[0043] In another embodiment, instead of being operated by the electric actuator (6), the control means (14) emits a signal or electrical impulse that acts on the release means to release the lock on the position support (3). Once released, the electric actuator (6) operates according to the command given by the control means (14).

[0044] According to another embodiment of the present invention, as shown in Figure 6, the electric actuator (7) is a movable device, preferably a cart that can be automatically moved to each position support (3). The cart comprises an actuating means (7.1) corresponding to the positioning means (3.6) of the support (3). The actuating means (7.1) is preferably in the form of an electric rotating shaft, preferably three in number, so that they correspond to three positioning means (3.6) configured to receive rotation of the actuating means (7.1) to position the tool (4). Thus, the first rotating shaft of the actuating means (7.1) is inserted into the first positioning means (3.6), thereby moving the support in the X direction using a worm gear mechanism; the second rotating shaft is inserted into the second positioning means (3.6), thereby moving the support in the Z direction using a worm gear mechanism; and the third rotating shaft rotates the third positioning means, which rotates the tool around the Y axis.

[0045] According to another embodiment, the movable cart is movable by an operator to a corresponding support (3), thereby allowing the actuation means (7.1) to be operated in accordance with commands given by the control means (14).

[0046] According to another embodiment, the actuation means (7.1) is in the form of a manual drill that can be actuated by an operator, thereby, in accordance with a command from the control means (14), the operator acts on the positioning means (3.6) on the corresponding axis, and when the positioning operation is complete, indicates to the control means (14) and awaits the next command.

[0047] Both the cart-type electric actuator (7) and the electric actuator (6) corresponding to the robot may consist of a single actuator, or one may be provided on each side of the conveyor (2) and act on the corresponding row of position support units (3).

[0048] In another embodiment, as shown in Figure 7, the electric actuator (8) may be fixedly positioned in the reconfiguration area (9). Therefore, when the position support (3) needs to be reconfigured, the operator is responsible for removing the position support (3) which is fixed according to the positioning, and then, once the position support (3) is available in the reconfiguration area (9), the electric actuator (8) engages with it, disengages it, acts on it by changing the orientation of the position support (3) according to a command from the control means (14), and then the position support (3) is re-engaged. Similar to the previous embodiment, the electric actuator (8) may also be able to change the tool (4). Once reconfigured, the operator can return the position support (3) to its original or new location and fix it in place. In this case, the work performed by the operator may also be performed by a robot. Alternatively, the operator may perform the reconfiguration work after the support (3) has been released according to a command from the control means (14).

[0049] In another aspect of the present invention, the system may include auditory and / or display means (15), such as a screen as shown in Figure 1, which indicates changes for the repositioning and / or relocation and / or tool (4) of each position support (3) to be made by the operator. For this purpose, electric actuators (6, 7, 8) first connect to and then release the support (3). Alternatively, the support (3) is simply released by the control means (14) without the need to connect the electric actuators (6, 7, 8). This allows the operator to act on the support (3) according to the instructions on the screen (15) which shows commands given by the control means (14) based on the new shape of the inserted part (1). Once the change is complete, the support (3) is re-engaged. In another embodiment of the present invention, the display means may also use augmented reality (AR) to display the changes to be made by the operator. This would display on the screen, through augmented reality software, the actions to be taken to obtain the necessary repositioning based on commands from the control means (14).

[0050] The reconfiguration parameters provided by the control means (14) may not be entirely correct, which may result in defects in the application of the covering, such as undesirable wrinkles. Alternatively, even if the reconfiguration parameters are accurate, there may be areas for improvement that could lead to better results. To resolve or improve these deficiencies, it is conceivable that an experienced worker, using their "master touch"—a skill based on their experience—may adjust the position support (3) by applying the necessary adjustments for the correct application of the covering material using the tool (4). Therefore, according to a practical embodiment of the present invention, the control means (14) is configured to record and process its manual adjustments in the machine's memory so that any adjustment errors are corrected when the shaped part (1) is inserted again in the future.

[0051] Furthermore, the system of the present invention may include software that determines reconstruction parameters based on the shape of a part (1) that is not present in the machine's memory, preferably a shape input via CAD, thereby also taking into account the master touch settings stored in memory in order to perform this calculation.

[0052] Furthermore, the system of the present invention may include a tool (4) wear recognition system such as a sensor, which identifies the wear that has occurred, and these wear parameters may be taken into consideration by the software described above for calculating reconstruction parameters.

[0053] According to one embodiment, once the electric actuators (6, 7, 8) are coupled and the support unit (3) is released, a master touch can be performed by an operator using a control device such as a push button in a manner that controls the positioning movement of the support unit (3). These pulse movements are recorded by the control means (14), and this information can be used to determine the adjustments that have been made.

[0054] In another embodiment, the operator performs a master touch when the actuators (6, 7, 8) are coupled and the support (3) is released. This allows the control means (14) to determine the adjustment made between the initial position and the final position when the actuators (6, 7, 8) are coupled.

[0055] In a further embodiment, after the support unit (3) is released by a signal emitted from the control means (14), the operator performs a master touch by directly acting on the support unit (3) while the actuators (6, 7, 8) are not connected. In this case, the position support unit (3) is equipped with a plurality of sensors (10), such as encoders, which record the position of the tool (4) by detecting the positioning adjustment made to the support unit (3) and transmit this information to the control means (14).

[0056] All of these features of the component coating system covered by the present invention aim to automate, reduce, and eliminate errors in the coating process, while simultaneously ensuring worker safety. Furthermore, a far more economical system is obtained than known solutions that use multiple electric robot support units. [Explanation of Symbols]
