    [0002] OBJECT OF THE INVENTION
    [0004] The following invention refers to a modular feeding system, which is intended to be used in the supply of elements to manufacturing machines or tools, preferably for punching machines, so that the configuration and design of the modular feeding system allows it adapt to different types of dimensions, lengths, thicknesses and thicknesses, of the piece to be supplied, as well as the possibility of configuring the feeding both manually and automatically.
    [0006] BACKGROUND OF THE INVENTION
    [0008] Currently, to feed the punching machines with the parts or elements to be punched or perforated, it is necessary to use feeders that position and transfer said parts to said machine, which must be configured according to the dimensions, geometries and weights of said parts, it being difficult for the same feeder to be configured to feed parts of different dimensions and geometries, having to use a specific feeder for each type of part.
    [0010] In other words, existing feeders are specifically designed based on the dimensions of the parts to be punched and / or the availability of floor space.
    [0012] This fact means that, if there is enough space in the plant, the feeder is oversized to be able to accommodate a larger type of pieces, with the consequent wastage of space, or on the contrary, the feeding is limited to a specific type of piece, It cannot be expanded or modified in case of modifying the type of part to be fed.
    [0014] Therefore, one of the problems that current feeders have is that their design does not have a flexibility that allows modifying it to accommodate different types of parts, unless they are oversized, being necessary for this to have enough space, taking into account that feeding smaller pieces in an oversized installation leads to a waste of floor space.
    [0016] Another common problem in this type of system is that current feeders comprise a manual or automatic regime, with no option of having one or the other depending on the needs of the process.
    [0018] DESCRIPTION OF THE INVENTION
    [0020] In order to solve the existing problems, indicated above, of the current systems for feeding parts or elements in manufacturing, machining, transportation or storage processes, the present invention consists of a modular feeding system. Said modularity allows the elements that make up said system to be configured by modules, which makes it possible to adapt said system according to needs, that is, being able to have more or fewer modules depending on the size and type of the pieces to be fed.
    [0022] Therefore, the modular feeding system comprises at least one feeder module comprising:
    [0023] - at least one table support configured to be fixed or supported on an external element of the modular feeding system. Said external element can be a floor or part of an external structure on which the modular feeding system can be seated and the table support can be one or a plurality of metal profiles that form a frame, preferably arranged vertically, which make the feeder module leg functions;
    [0024] - a roller table supported on at least one table support, although preferably supported on two table supports joined at their ends, where said roller table comprises:
    [0025] or a plurality of rollers arranged in parallel, one after the other, configured to move elements in a longitudinal direction, connected at their ends to a frame of the roller table. The fact that the rollers are arranged in parallel means that they are positioned continuously, separated by a suitable distance for the configured function. The joints of the rollers with the frame are preferably of the type that allow the roller to rotate on itself with respect to the frame, which can comprise two or more metal profiles to which the ends of the rollers are attached.
    [0026] - at least one transverse pusher connected to the frame of the roller table, preferably attached to said frame, said transverse pusher configured to push, in a transverse direction, the elements to be fed by the modular feeding system, to a longitudinal push position , said elements being located on the plurality of rollers of the roller table. The transverse pusher preferably comprises a stop that limits the transverse movement of the elements to the longitudinal thrust position.
    [0028] Furthermore, the modular feeding system comprises a motorized carriage connected to at least one feeder module, said motorized carriage configured to detect the elements to be fed positioned on the roller table, located in a longitudinal thrust position, and to move, pushing or pulling, said elements in the longitudinal direction, on the plurality of rollers.
    [0030] That is to say, that by means of this embodiment, the elements to be fed are allowed to be placed on the roller table in a manual way, to be subsequently positioned by the transverse pushers to a suitable position for their longitudinal movement. This longitudinal movement is carried out by pushing the motorized carriage of the elements to be fed onto the rollers of the feeding module or of the feeding modules that make up the modular feeding system. In other words, a single motorized carriage is sufficient to push the elements, regardless of the number of feeder modules that make up the modular feeder system, or of the transverse pushers included in each feeder module. The number of feeder modules included in the modular feeder system depends on the size and geometry of the elements to be fed, so that the more feeder modules are available the longer the part to be fed.
    [0032] In one embodiment, the modular feeding system comprises a plurality of feeder modules connected in series, arranged in a longitudinal direction, where the motorized carriage is configured to move the elements to be fed in the longitudinal direction, on the plurality of rollers of the plurality of the feeder modules.
    [0033] In one embodiment, the transverse pusher comprises a linear actuator arranged in a direction perpendicular to the longitudinal direction of movement of the elements, which is the one that carries out the push in said transverse direction.
    [0035] In one embodiment, the modular feeding system comprises an automatic transverse feeding system, of elements to be fed, to the feeder module, where said automatic system comprises at least one transverse feeder fixed to a feeder module, where said transverse feeder comprises:
    [0036] - a first motorized means configured to move the elements to be fed, by the modular feeding system, in a lateral direction, transverse to the longitudinal direction of the feeding module, until said elements are positioned on at least one roller table of a feeding module; and
    [0037] - a support of the transversal feeder configured to be fixed or supported to an external element of the modular feeding system and to support the first motorized means.
    [0039] In other words, industrially, the modular design of the system makes it possible for the transverse feeding modules to be easily integrated into the feeding system, in the event that an existing manual feeding line has to be transformed, which lacks any type of automatic feeding. , to another with automatic cross feed. Therefore, the reverse process is also possible, that is, removing the cross feed modules to transform an existing automatic feed process to a manual feed one.
    [0041] Likewise, thanks to the modularity of the system, the length of the modular power supply system can also be modified by adding or removing power modules connected in series, depending on the lengths of the elements.
    [0043] In one embodiment, the automatic transverse feeding system of elements to the feeder module comprises two or more transverse feeders aligned and configured to rest on different table supports of the modular system, where said automatic transverse feeding system comprises an orientation detector of the displaced element. configured to measure or determine the longitudinal orientation of said element. The operation of this detector works in such a way that, until it is achieves proper alignment of the transported element by means of the movement of the first motorized means, the movement of the elements does not take place until they are placed on the roller table of the feeder module
    [0045] The motorized means can be rollers, chains or transmission belts, configured to carry out the movement of the elements. Moving the elements to place them on the roller table may require other devices or make use of gravity.
    [0047] In one embodiment, the table support comprises an elevator comprising a second motorized means, where:
    [0048] - the first motorized means is configured to move elements until they are positioned on the second motorized means;
    [0049] - the second motorized means is configured to move the elements, displaced by the first motorized means, in the same lateral direction, until they place said elements in a position outside the first motorized means;
    [0050] - the element elevator located on a table support is configured to move, in a downward vertical direction, the elements displaced by the second motorized means, until placing them on at least one roller table of a feeder module.
    [0052] In this way, once the elements to be fed are located in a position outside the first motorized means, the elevator can vertically move the element to be fed without being interrupted or making contact with said first motorized means, avoiding affecting its position. .
    [0054] With this embodiment, in the case of having an orientation detector, it is configured to measure or determine the longitudinal orientation of the element displaced by the first motorized means, and not to transfer it to the second motorized means until adequate alignment is achieved. of the transported item.
    [0056] The element elevator preferably comprises a linear actuator located in a vertical position, which is the one that performs the movement in said vertical direction, of the element to be fed, until it is positioned on the roller table, where it can be moved by the carriage. motorized. Once that element has been moved, the Lifting element can be raised again to repeat the same automatic feeding process.
    [0058] In one embodiment, the at least one cross feeder is aligned and configured to rest on a table support of a feeder module. That is, since a modular feeding system can comprise one or more transverse feeders and that preferably, said transverse feeders are positioned next to the supports of the tables included in the modular feeding system, the transverse feeders can be supported on said supports to favor a suitable load distribution for the system.
    [0060] In one embodiment, the element lift is located in an interior recess of the table stand. In this way, the structure of the table support is used to also support the lift.
    [0062] In one embodiment, the motorized means, both the first and the second, comprise a displacement mechanism comprising a chain connected to a motor.
    [0064] In one embodiment, the at least one cross feeder comprises an element loading zone comprising a plurality of free rollers and is configured to accumulate elements prior to being moved by the first motorized means. In this way, the elements can be accumulated in said loading area and let them feed according to the needs of the process.
    [0066] In one embodiment, the element loading zone of the at least one transverse feeder is separated from the first motorized means by at least one safety photoelectric barrier. By means of this barrier, possible interference in the process is detected, being able to stop the movements of the parts of the system in case of detection.
    [0068] In one embodiment, at least one feeder module of the modular feeding system comprises a scrap tray configured to remove excess parts of the elements moved by the motorized carriage. This tray allows the passage of the elements to be fed but also allows the removal of components from said elements that are not intended to be fed.

    [0086] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0088] As can be seen in Figures 1 and 2, the preferred, simplest embodiment of the invention of the modular element feeding system (20) is based on a feeder module (1) comprising a roller table supported on two table supports (2), located and fixed each of said supports (2) to each end of the table.
    [0090] As can be seen in any of Figures 1 and 2, this table comprises five rollers (4), parallel to each other, fixed to a frame (3) by rotating joints, configured to allow said rollers to rotate on themselves. Said frame (3) comprises at least two metal profiles which are supported and fixed by means of fixed joints to the supports (2).
    [0092] Also in Figures 1 and 2 it can be seen that each feeder module (1) comprises two transverse pushers (5) rigidly fixed to the frame (3) of the roller table, where said transverse pushers (5) each comprise a linear actuator, and are configured to push the element (20) to be fed in a transverse direction, on the surface of the rollers (4) up to a stop, so that said elements (20) are positioned in a suitable direction to be pushed in a longitudinal direction. That is, in a direction perpendicular to the rollers (4), so that their rotation favors the sliding of the elements (20).
    [0094] The supports (2) are provided at their base with corresponding means for leveling and mooring to the ground and the number and distribution of the transversal pushers (5) can vary depending on the number of connected feeder modules, the length of the element to be fed (20) and the way the system is loaded (manual or automatic).
    [0096] In figure 3 it can be seen that the modular power supply system comprises five power supply modules (1) connected in series, where the element (20) consists of a metal profile of small width compared to its length, so that these five modules feeders (1) are sufficient to support and move the element (20). To perform the longitudinal movement, the modular feeding system also comprises a motorized carriage (6) that is capable of detecting when the element (20) is in a suitable position for its longitudinal movement, anchoring or clamping said element (20) and push it in the desired direction.
    [0098] With this preferred embodiment, the elements (20) to be fed have to be positioned manually on the roller tables, so that the transverse pushers (5) and the motorized carriage (6) are the ones that move the elements (20) sequentially, one at a time.
    [0100] As can be seen in Figures 6 and 7, in the other preferred embodiment of the invention, the system comprises a series of transversal feeders (9) that allow the automatic feeding of the elements (20) to the modular feeding system. One of these transverse feeders (9) is shown in detail in Figure 4, where it can be seen that each of them comprises a first motorized means (11) supported, at a first end, on a feeder support (10) and at a second end on the table support (2).
    [0102] Figures 5A-5D show the steps performed by said transverse feeder (9), so that in Figure 5A a set of elements (20) to be fed are shown, supported on the first motorized means (11), an elevator (7) driven by a linear actuator, said elevator (11) located in a lower position, being configured to move a second motorized means (8) between two positions, the lower and the upper.
    [0104] In figure 5B, it is shown how the elevator (7) has risen to the upper position, so that the second motorized means (8) is at the same height, that is, flush with the first motorized means (11), so that the elements (20) that are supported on the first motorized means (11) they can be moved until they are positioned on the second means (8), when it has been determined by means of an orientation detector that the alignment of the element (20) is correct, as shown in figure 5C. Once an element (20) has been positioned on said second motorized means (8) and is no longer on the first motorized means (11), the elevator (7) can descend to its lower position, as shown in the figure 5D, being flush, or at the same height, as the rollers (4) of the roller table. Once the element (20) is on said table, it can be placed by the transverse pushers (5) to a suitable position for its longitudinal thrust.
    [0106] When these steps have finished, they are restarted again until all the elements (20) supported by the first motorized means (11) have moved.
    [0108] As can be seen in figure 6, the system can comprise as many transverse feeders (9) as are considered necessary, being normally dependent on the length of the elements (20) to be fed, and being preferably supported and aligned with the supports of the table (2), so that the distribution of loads and the transfer of the elements (20) is as continuous as possible.
    [0110] The wiring and modular design of the modular power supply system allows the system to be adapted according to needs and provides total flexibility to be able to adapt to various configurations, simply by adding or removing power supply modules.
    [0112] Likewise, the wiring and modular design of the system also allows it to be programmed with a partial activation of the transverse feeders (9), in those cases in which the length of the element to be fed is clearly shorter (that is, between half or two-thirds) to the nominal length for which the main feeder line was designed.
    [0114] Preferably, the elements to be fed can be distributed along the transverse feeders (9), in two loading zones, separated by a safety photoelectric barrier (12), shown in figure 7.
    [0116] In this way, an inner zone can be distinguished, comprising the corresponding motorized means (6, 8, 11) for moving the elements (20), and an outer zone, away from the feeder modules, with free rollers, where the The user can unload parts manually with industrial lifting elements and that can act as a warehouse or deposit of the elements (20) until their treatment is required.
    [0118] The photoelectric barrier (12) allows any intrusion from the outside to the interior zone to cause a detection and safety shutdown of the system process.
    [0120] As can be seen in figure 8, one of the feeder modules (1) of the system, the one that best adapts to the situation in which the user has established, can comprise a tray (13) for the discharge of remnants ( rest of the element that is not punched), to avoid that said remnants can affect the process for which the elements are fed (20).
    [0122] Therefore, the modular design of the present modular feeding system described allows, on the one hand, to adapt its dimensions to the needs of the user (adding or removing feeder modules) and, likewise, makes it possible for the automatic transverse feeders to be integrable in case of that a line with automatic feeding is required. In addition, the removable joints allow the storage of each of the components that are part of the system to occupy, separately, a reduced space.
