OPTIMIZED EQUIPMENT FOR THE ASSEMBLY OF SEMI-FINISHED PRODUCTS FOR THE PRODUCTION OF THERMAL BREAK PROFILES

Description

Optimized device for assembly of semi-finished products for the production of profiles thermal cut. DESCRIPTION The present invention relates to a apparatus optimized for the assembly of semi-finished products for the production of profiles thermal cut. Thermal break profiles are known generally made up of at least two semi-profiles in aluminum, so-called “shells”, obtained by extrusion and connected to each other by means of interposition of one or more connecting partitions elongated shape, so-called “bars”, in thermally insulating material of the type polyamide or other plastic material. Each semi-profile is equipped with at least one longitudinal hollow, which is delimited by two opposing ribs, so-called “hammers”, one of which is deformable. The two semi-profiles are positioned side by side with their respective quarries two, two facing each other to define at least one location housing a corresponding bar and with the relative deformable ribs arranged on the same side of the bar. These profiles are widely used in the energy-saving window and door production sector energetic, in which the two semi-profiles are facing one inward and one outward of the environment in which the window frame is mounted, with the interposition of an air chamber, defined between the semi-profiles themselves and the bars, which acts from thermal barrier. The production process of a profile thermal cutting involves the following phases processing: – knurling of the grooves provided on the pair of semi-profiles to be assembled; – introduction of at least one long bar a corresponding pair of quarries between them look at the semi-profiles placed side by side to obtain a semi-finished product; – rolling of the deformable ribs obtain the tightening of at least one bar within the relevant quarries and, therefore, the assembly of the profile. There are several types of devices known for carry out the knurling phases of the semi-profiles and of introducing one or more bars between the semi-profiles themselves. A first version of the known apparatus includes two knurling machines working in parallel, one on each semi-profile from assemble, and a third insertion station of the bars along the knurled grooves of the two semi-profiles to obtain the semi-finished product. After performing the knurling, each semi-profile must be moved from the area of unloading of the relevant knurling machine to the bar insertion station, in which the two semi-profiles must be positioned one next to the other on top of the other with their respective quarries facing each other. One of the two semi-profiles must, therefore, be overturned and held in a suspended position above to the other one at the station insertion of the bars. This known type solution is not free from drawbacks. First of all, foreseeing three distinct processing areas with respective machines and equipment (two for knurling of the semi-profiles and one for the insertion of the bars), requires adequate space for installation and is expensive. Furthermore, the need to move both semi-profiles towards the insertion station, moreover by overturning one of the two and keeping it in reversed position, requires the intervention of different operators and lengthens the time required for complete the processing, with reduction of the productivity and increased costs to perform the pre-assembly of each profile. Again the handling of semi-profiles involves the risk that they suffer impacts resulting in damage, especially if already painted. To partially solve these drawbacks is known a second version of pre-assembly apparatus which provides for a first station where the knurling is performed a first semi-profile using a first machine knurling machine and at the same time the insertion of a bar for each quarry to obtain a first semi-finished product and a second machine knurling machine for the second processing semi-profile and the simultaneous coupling with the first semi-finished product to obtain the profile pre-assembled. The first semi-finished product, consisting of from the first semi-profile coupled with one or more bars inserted into the relevant slots, must be transferred downstream of the second knurling machine, in so that the second semi-profile coming out of it pair along the bars completing the pre- assembly. In the transfer phase it is expected to turn the first semi-finished product over to position it valley of the second knurling machine in position upside down, with the bar(s) protruding towards the low. In this case, in addition to the risk of damage the first semi-profile, it turns out quite complicated to keep it in position correct when inserting the second semi-profile, preventing it from decoupling from the bars not yet tightened into their respective slots. In one variant it is foreseen that the first semi-profile with one or more bars comes positioned downstream of the second knurling machine with the bars facing upwards and that the second knurling machine works from the bottom on the second semi-profile positioned with the relative slots facing downwards, so as to mate along the bars, protruding upwards from at the first semi-profile, upon exiting the machine same. Even in this case, although it is not the overturning of the semi-finished product is expected, the the need to move it involves stretching cycle times, in addition to the risk of damage it. Both of these solutions, however, involve the need to provide two machines knurling machines and an adequate number of operators those responsible for supervising the processes and managing the movement of the first semi-profiles Therefore, this second known solution too, although it is an improvement over the previous, presents bulk and costs of installation not negligible. Furthermore, even in in this case, the need to move the first semi-profile with bars to couple it to the second semi-profile requires the intervention of operators and consequent waiting times execution that negatively impact costs and on processing productivity. The purpose of this invention is to to create an optimized device for the assembly of semi-finished products for production of thermal break profiles that are capable of improve the known technique in one or more of the aspects indicated above. Within this task, one purpose of the found is that it is compact in size in order to facilitate its installation. A further aim of this invention is to to reduce the number of machinery and equipment used to reduce the cost of purchase and limit maintenance interventions required. Another purpose of this invention is to minimize the need for intervention by operators in charge, in order to reduce the use of labor and the resulting operating costs. Not least, the present invention has the following purpose: that of not requiring the movement of the semi-profiles between one processing phase and another in order to eliminate the resulting downtime and the risk of damaging the semi-profiles, optimizing productivity and efficiency process. Furthermore, the present invention aims to the aim of overcoming the drawbacks of the known technique as an alternative to any existing solutions. Not least, the aim of the invention is to to create an optimized device for the assembly of semi-finished products for production of thermal break profiles that are of high reliability, relatively easy production and at competitive costs.

The electronic management and control unit It can be a conventional electronic board or programmable logic controller (PLC) capable of manage the operating cycle of the device 1 which will be described below. In an alternative form of implementation (figures 15-16) assembly station 3 comprises two working groups 5 of the type described above, arranged in a mirror-like manner on opposite sides of the operational management D. The two working groups 5 they are aligned with each other transversally to the operational direction D. In this case the apparatus 1 can work both semi-finished products S composed of semi-profiles S1 and S2 and from a single partition connection B (figure 4), activating a single group of work 5, which semi-finished products S composed of semi-profiles S1 and S2 and two connecting partitions B (figure 17), activating both working groups 5. In this case the above detection means described may be unique to the station assembly 3 and provide a first sensor 29, a second sensor 30, a third sensor 31 and a fourth sensor 32 for the actuation of both working groups 5. With reference to a work cycle to obtain a semi-finished product S composed from the semi-profiles S1 and S2 and from a single partition connection B the operation of the device 1 is the following. The first semi-profile S1 is loaded onto the support surface 14 of transfer group 2 arranged along the operating direction D, with the at least one first C1 cavity facing upwards and the front end, with respect to the direction of feed A, corresponding to the tool knurling tool 9. The support surface 14 is positioned at a first working height along the second axis of A2 recording processed from the electronic management and control unit in function of the geometry and dimensions of the first semi-profile S1. The connecting septum B is positioned between the clamp 12 tightened on the second edge B2 in the socket configuration and the guide 21 arranged in the operational configuration in contact with the first margin B1. It should be noted that a section of end T of the connecting septum B is kept protruding from the clamp 12 towards the knurling tool 9 (figure 5). The share of the working configuration in where the connecting septum B is positioned is determined by the electronic unit in operation of the geometry and dimensions of the semi-profiles S1 and S2 in progress and remains the same for the entire production cycle. The electronic unit positions the tool knurling tool 9 in the first position along the first A1 recording axis and the contrast organ 19 lower in the operating configuration to contact with the first semi-profile S1. When the first sensor 29 detects the presence of the first semi-profile S1 in correspondence with the knurling group 8, the electronic unit of management and control drives the rotation of the knurling tool 9 in the first direction V1. The first semi-profile S1, driven by action of the knurling tool 9 along the direction operational D in the direction of advancement A, yes approach the connecting septum B to insert it along the end section T with the relative first edge B1 inserted into the first slot C1 (figure 6). Preferably in this first phase of insertion of the rotation speed of the knurling tool 9 is maintained reduced. When the second sensor 30 detects the presence of the first semi-profile S1 upstream of the guide 21, the electronic unit deactivates temporarily the means of operation in rotation 10 of the knurling tool 9 and activates the fifth actuating means 22 to bring the guide 21 in the rest configuration (figure 7) in order to allow the passage of the first semi-profile S1. Following the active electronic unit the rotating drive means again 10 of the knurling tool 9, always in the first towards V1 and with a higher speed than the previous, to complete the knurling of the first C1 cavity and the insertion along the septum of junction B. When the rear end of the first semi-profile S1 passes the fourth sensor 32 the electronic unit reduces the speed of rotation of the knurling tool 9 (figure 8), until it stops when the first sensor 29 detects the absence of the first semi-profile S1 (figure 9). At this point the electronic unit activates the any accompanying means to complete the insertion of the first semi-profile S1 along the connecting septum B. Before starting the processing of the second semi-profile S2 the electronic unit operates the positioning of the support surface 14 at a second work quota along the second axis of Recording A2, of the knurling tool 9 in the second position along the first axis of A1 registration and contrast organ 19 superior in operational configuration. The second semi-profile S2 is then positioned on the support surface 14 along the operational direction D (figure 10) and is moved towards the knurling tool 9. When the first sensor 29 detects the presence of the second semi-profile S2 in correspondence with the knurling group 8, the electronic unit of management and control drives the rotation of the knurling tool 9 in the second direction V2. The second semi-profile S2, driven by the action of the knurling tool 9 along the direction operational D in the direction of advancement A, yes approaches the connecting septum B and then inserts itself along the end section T with the relative second margin B2 inserted into the second slot C2 (figure 11). Preferably in this first phase of insertion of the rotation speed of the knurling tool 9 is maintained reduced. When the third sensor 31 detects the presence of the second semi-profile S2 upstream of the clamp 12, the electronic unit temporarily deactivates the tool rotation drive means 10 knurling tool 9 and operates the third means of drive to bring the clamp 12 into the release configuration (figure 12), so as to allow the passage of the second semi-profile S2. In this condition the connecting septum B however, it remains in its original position in how much is coupled in the first slot C1 of the first S1 semi-profile resting on the support surface 25. At the same time the feedback is brought of end of travel 28 in the active configuration. Following the active electronic unit the rotating drive means again 10 of the knurling tool 9, always in the second towards V2 and with a higher speed than the previous to complete the knurling of the second C2 cavity and the insertion along the septum of junction B. When the rear end of the second semi-profile S2 passes the fourth sensor 32 the electronic unit reduces the speed of rotation of the knurling tool 9 (figure 13), until it stops when the first sensor 29 detects the absence of the second semi-profile S2. At this point the electronic unit activates the rotation of the motorized roller 27 to complete the transfer of the semi-profiles S1 and S2 and of the connecting septum B along the operating direction in the direction of advancement A until they reach hit against the end stop 28, completing the insertion of the semi-profiles along in set itself to obtain a semi-finished product S. When the end of the first semi-profile S1 passes the fifth sensor 33 the unit electronics deactivates the motorized roller 27 (figure 14). In case device 1 is equipped with two groups of work 5, each of them replicates in the operational phases described above simultaneously on semi-profiles S1 and S2 with reference to respective first and second quarries C1 and C2. According to the invention, a assembly method of a semi-finished product S for obtaining thermal break profiles which It essentially includes the following phases: - a phase of supply of a first S1 semi-profile equipped with at least one first slot C1 longitudinal, of a second semi-profile S2 provided with at least one corresponding second longitudinal C2 cavity and at least one septum of connection B having a first and a second margin B1 and B2 opposed to each other, – a first phase of movement along the operating direction D in the direction of advancement A of the first semi-profile S1 arranged at a first work quota and with at least one first C1 quarry facing upwards through an area of process in which knurling is performed of the first quarry itself and the simultaneous insertion of the first knurled C1 slot along the corresponding first margin B1 of the septum of junction B, - a second phase of movement along the operating direction D in the direction of advancement A of the second semi-profile S2 arranged at a second share of work and with at least one second C2 hollow facing down through the area of processing in which the knurling of the second slot itself and the simultaneous insertion of the second C2 cavity knurled along the corresponding second margin B2 of the connecting septum B to obtain a semi-finished product S for the production of a profile thermal cut, during the above mentioned handling phases the at least one connecting septum B being maintained stuck in a downstream work configuration of the processing area along the direction of operational D in the direction of advancement A. In practice it has been found that the finding achieve the intended task and goals creating an optimized device for the assembly of semi-finished products for production of thermal break profiles of overall dimensions compact, reducing the number of equipment expected and which do not require particular interventions by the operators in charge, in particular for the movement of semi-profiles during the assembly.
