Description of a preferred embodiment

Next, a system of transport used to carry boxes and the like from a point Initial to an end point. Said system is formed by a circuit, as shown in general in the figure 35, which in turn consists of a plurality of modules of transport, straight and curvilinear trajectory, which are coupled to each other by well known means (so it is not going to go into more detail in your description), defining a trajectory by which the elements to be moved are moved transported

Usually, each of the modules Transportation consists of two main parts, one lower support structure and means of transport located in the upper part through which the elements to transport (C). In the embodiments shown here, the means of transport consist of a plurality of rollers driven by middle of a drive belt, although it will be evident by any expert in the field that other means of transport, such as transport bands.

Then they will be described in a way detailed the various parts of which the transport modules:

       \ vskip1.000000 \ baselineskip
    

Support leg

The support leg, indicated in general with reference (1), is the main element that makes up the Support structure of each of the transport modules. In in particular, as seen more clearly in Figures 1 to 3, said support leg comprises an elongated material profile metallic that has a central section (1a) that has a double undulation (101) that confers rigidity and inertia using little sheet thickness Said central section (1a) also presents a series of perforations (102) spread over their entire height that They allow the fixing of different crossbars. Mention that the crossbar arrangement depends on the height and width of each transport module

The upper end section (1b) that has a vertical flat area (103) that adapts to side profiles located in the transport modules (described in greater detail later).

In addition, the profile has an end section bottom (1c) that has a right angle bend of the profile, of so that there is a horizontal and partially flat support base. In this lower end section (1c) a ripple is included central that provides a greater degree of rigidity and some holes (104) on the support base that allow fixing, for example, by Anchors or hardware elements.

In an alternative embodiment of another leg of support (1 '), according to figure 10, the end section upper (1b ') can incorporate a folded sheet portion (105) in order to be used as a means of support for transport. In the section of the lower end (1c ') incorporate threaded rods (106) and nuts (107) that They allow height adjustment of the means of transport.

       \ vskip1.000000 \ baselineskip
    

Support structure

This structure is what makes up the part bottom of a transport module that supports the means of transport. Basically, this structure is constituted by two support legs (1), as described above, facing each other each other that are joined by one or more crossbars (2), of such way they form a flat lattice structure, where the number of crossbars (2) can be variable as well as its arrangement in function of the height and width of the transport module.

Figures 5 and 6 show two realizations of the support structure within the scope of the present invention, the one of figure 6 being provided with a single inclined crossbar (2) while, in the case of figure 5, it have provided two crossbars (2) inclined in directions opposite.

The support structure is advantageously provided with a regulation system that allows to regulate in height and tilt the support legs in a simple and practical way, of such that it does not require any additional elements. This is achieved by gradually changing the profile with double corrugation which forms the support leg (1), so that in the section of upper end (1b) has a partially flat surface that incorporates two elongated grooves or collisions (108) and inclined with respect to the longitudinal axis, from which, in combination with the horizontal grooves described above, existing in the vertical wall of the side profiles, a relative displacement of the lateral profile of the means of transport with respect to the support leg (1), both in a vertical direction as angularly, as indicated by arrows in figure 8.

Another embodiment of support structure, in which common parts with the previous Realizations have the same numerical references. This support structure is also formed by two support legs (1 ') joined together with a single horizontal crossbar (2 ') and variable in length depending on the width of the means of transport. Every end of the crossbar (2 ') joins the support legs (1') by means of four bolted joints (4) that ensure stability and rigidity of the set with a single crossbar. In this case, the crossbar (see figures 12, 13 and 14) is made up of a sheet profile folded along its entire length, with a thin section and specially designed folds, which confers sufficient inertia and rigidity to the crossbar in question to fulfill the stiffening and joining functions screwed at its ends. In particular, they are appreciated longitudinally two undulations (201), which protrude in directions opposite each other, and each of these undulations (201) suffers in its 2 extremes a progressive deformation and a discontinuity such that define accommodations through which said pass hardware elements. The described arrangement avoids the use of welding techniques or additional joining elements.

       \ vskip1.000000 \ baselineskip
    

Transport module

The transport module, indicated as general with reference (5), are the modular parts that form part of a circuit that are generally comprised of the support structure described above, indicated general with reference (6), and means of transport superiors through which the boxes or the like move to be transported from one point to another.

In addition, two side profiles are provided (7) that run parallel to each other, arranged one on each side of the means of transport between which the means are arranged of transport, in this case represented, a plurality of rollers (8) which are coupled to such lateral profiles (7) through drills or perforations provided along the profiles sides (7) described below in detail.

Depending on the dimensions of the elements to be transported, especially in the transverse direction to the transport direction, the width of each transport module (5) it will be different to adapt to such dimensions, for which the length of the crossbars (2) of the support structures (6), as well as their quantity and arrangement Between the support legs.

The transport modules, as it has been mentioned above, they can have a rectilinear trajectory or curvilinear, according to the user's needs.

Now, making particular reference to a straight transport module, shown in figure 15, the side profiles (7) have a substantially shaped section "S" such that it allows its adaptation to different means of transport, whether rollers (8) or bands or their different variations or the respective drive means used. In Figure 16 shows a similar transport module characteristics to that shown in figure 15 with the main unlike the means of transport installed, where in the Figure 16 such means of transport are of the band type (9).

Entering more detail in the side profile (7), presents a central section (7a) (which adopts a provision of vertical wall when mounted on the transport module) where there is a series of perforations at different heights and geometries. In this central section (7a), the main components of the means of transport, such as transport rollers, driving rollers, etc.

As can be seen in detail in the figure 18, the lateral profile (7) also has a lower section (7b) and a lateral fin (7c) that confers rigidity to such lateral profile and that facilitate the channeling of cables and fixing some necessary elements for the proper functioning of the media of transport and; an upper section (7d) and an upper section (7e) which also confers rigidity to the lateral profile (7) and facilitates the fixing of additional elements, such as channel detectors or profiles, which are described with more detail later.

In regards to the different perforations provided on the side profiles (7), are arranged The following perforations:

-

Hexagonal contour perforations (10), separated equidistant by a step "e", the which are used for fixing without roller screws transport;

-

Drills (11) separated in shape equidistant with a step "p" which is triple the step "e" and are used for the passage of the associated electrical connections with the rollers and the detection elements;

       \ global \ parskip0.930000 \ baselineskip
    

-

Additional drills (12) separated by an "e" step;

-

Four-slot groupings (13) arranged horizontally that are essentially intended for fixing the support legs (1) and which are linked directly with the height and inclination adjustment means of the support legs (1), as seen in the figure 9;

-

Drills (14) interspersed between each two groups of slots (13) with various functions, among which are the crossbar fixing (2).

       \ vskip1.000000 \ baselineskip
    

Additionally, in the lower section (7b) of the side profile (7) double perforations can be provided (15), having provided two drills at the same pace as the groups of four slots (13). Similarly, on the lateral fin (7c) bottom can be arranged a series of holes (16) normally located at each step "p" that are used for fixing additional items

As can also be seen in figures 20 and 21, in the upper section (7d) of the lateral profile (7) a series of holes in which some of larger diameter are inserted (17) with ones of smaller diameter (18). The largest diameter holes (17) are used for fixing detection photocells (19) for the items to be transported (boxes and the like), while that the smaller diameter holes (18) are used for the fixing reflection mirrors (20) for correct operation of said detection photocells (19).

The detection photocells (19) used they have the peculiarity of being cylindrical and launching a beam of detection in a direction perpendicular to the cylinder axis of the Photocell body. The cylindrical shape and its small size allow it to be fixed directly on the side profile (7) on one side of the transport module, in particular in the hole (17) without the need to use additional brackets, either for fixing in the lateral profile (7) as to regulate the working angle of the detection beam At the same time, the connection part of the detection photocell (19) corresponding to the bottom of it is not exposed to possible accidental blows due to the "S" shape of the cross section of the side profile (7).

It is worth mentioning that the length "L" of the side profiles (7) is a multiple value of the main step "p" and each side profile (7) starts, regardless of its length, always with a drill that is in step "p".

Next we will refer to a transport module with curvilinear trajectory and to figures 22, 23 and 24, indicated generally with reference (21), which it presents some differences with respect to the transport module of straight path (5) described above. In In particular, this transport module is characterized by having lateral profiles (22, 23) with a predetermined radius of curvature in which the means of transport are supported. The structure of support (6) is the same as in the transport module (5).

Such curved side profiles (22, 23) they have a section in the form of "L" with the particularity that in the case of the outer curved profile (22) the "L" section is reversed, which facilitates the productive process of the curved both in the inner curved profile (23) and in the profile curved outside (22). The inner curved profile (23) has a bent fin (23a) at an angle of approximately 9 0 degrees in the lower end or flange while the outer curved profile (22) has a bent fin (22a) at the end or flange higher. Such bent fins provide the side profile curved greater rigidity and inertia to the section of the latter to withstand the minimum thickness required.

The curved side profiles (22, 23) also they have a plurality of through holes, see Figures 23 and 24, which are the following:

-

Hexagonal contour perforations (24) equidistant by an "ei" step in the curved profile inside and a step "ee" in the curved profile outside with the purpose of housing the ends of the rollers without screws transport (8);

-

Drills (25) interspersed between hexagonal perforations and one step multiple of the steps "ei" and "ee" respectively, in order to fix brackets used to fix channeling profiles;

-

Drills (26) located one step away multiple of the steps "ei" and "ee" for fixing the elements of detection of the means of transport;

-

A series of pairs of horizontal grooves (27) located one step away multiple of the steps "ei" and "ee" for the purpose of fix the support legs (1, 1 ').

       \ vskip1.000000 \ baselineskip
    

Mention that the inner curved profile (23) always has the same radius as the profile radius curved outside (22) is variable depending on the width of the media Of transport.

It is possible to get different angles or curve lengths varying the length of the curved profiles, both inside and outside, at intervals equal to the step "ei" and "ee" respectively between perforations for transport rollers (8).

       \ global \ parskip1.000000 \ baselineskip
    

Protection element

As shown in Figures 25 and 26, it provides at each junction point between the side profile (7) and a transport roller (8) a protection element (28) in which the transport roller (8) is partially inserted, being said protection element (28) fixed on the inside of the lateral profile (7). It has the function of preventing personal injury due to the movement of the transmission belts (29) and the transport rollers, wherein said transmission belts (29) gear with transmission heads (30) located at the ends of said transport rollers (8). Thus, the possibility is eliminated that you can accidentally insert your fingers or hands into the transmission belt travel (29) and, therefore, prevent that due to the movement of said transmission belt (29) and the rotation of the transport rollers (8) fingers or hand can be absorbed and damaged by said moving elements.

As can be seen in greater detail in the Figures 27 and 28, this protection element (28) is shaped by a single piece of injection moldable plastic material, which it has a flat base provided with a central section (28a) with a through hole (28b) through which a spindle head is inserted transmission (30) of the end of the transport roller (8) and two noticeably semi-cylindrical side sections (28c) opposite between yes that partially wrap the transmission head (30) of the transport roller (8) and those protruding from each of the lateral sections noticeably semi-cylindrical straight fins (28d).

Channel profile and fasteners

Clamping elements are available (31, 32) intermediate between the side profiles (7) and the profiles of channeling (33) that prevent the elements to be transported from divert from the transport zone on the transport rollers (8). Two different types of fasteners are provided described below:

A first fastener (31) that places the guiding surface on the same vertical side wall of the side profile (7) of the transport module (5, 21). The element of clamp (31) is made of a single piece of sheet metal with several folds that give it a structural rigidity and allow to hold the channeling profile without the need for a screw connection. As can be seen in figures 30, 31 and 32, the clamping element (31) is formed by a vertical section of folded sheet in the form of "L" (31a), having a lower support base (31b) formed by two parts of the same piece folded over each other and provided with through holes. Partially available a fold as a wave in a longitudinal direction (31c) (vertical direction) that provides structural rigidity. In the part There are two folded fins (31d, 31e), one fin (31d) with double projection up and down and a fin (31e) with a single outgoing down. These two fins (31d, 31e) are intended for enter into the "C" shaped section of the channeling profile (33) and, by turning the element of clamping, both fins (31d, 31e) and their protrusions remain fitted in such a way with the channeling profile (33), which get a strong enough bond, after fixing more than a support of the same channeling profile on a profile side of a transport module (5, 21).

A second fastener (32) is that which presents a general configuration inclined and shown in the Figures 33 and 34. In particular, this second fastener It is also made of a single piece of sheet metal with several folds that confer rigidity and, at the same time, give the suitable way to hold the channeling profile (33) without the need for screw connection with said channeling profile (33), as also happens with the clamping element previously described. The body of the clamping element (32) it presents an inclined section (32a) of folded sheet in the form of "U" with a lower support base (32b) formed by two parts of the same piece folded over each other. In the upper zone of the inclined section (32a) two fins (32c, 32d) are included one fin (32c) with double projection up and down and the other fin (32d) with a single protrusion down, as seen clearly in figure 34. These two fins (32c, 32d) are intended to be introduced inside the channeling profile (33) in the form of "C", and by turning the piece in respect to the profile, both fins remain and their protrusions embedded in such way with the profile that a union is achieved sufficiently strong, after fixing more than one support of the same profile of channeling (33) on a side profile (7) of a module transport (5, 21).

The control of the transport circuit depicted in figure 35 is carried out by the configuration of a plurality of divisions, also called henceforth as plots, which should not necessarily physically match the various transport modules that They are part of the transport circuit.

Such plots should be understood as units of electrical and electronic control responsible for controlling the speed, acceleration, object detection across the track of circulation (defined by means of transport).

This control system allows you to configure and vary at any time, independently of the division Physics of transport modules (5), characteristics Functional plots (40). This is achieved thanks to the fact that the different control elements that are provided in each plot are easily pluggable at any point at along the length of the transport modules and, allow their Once configured separately in terms of parameters, such as speed or acceleration independently from the rest of the circuit.

The detection system or working mode can be configured in each plot (40) independently of the others plots and physical sections of transport. To do this, how can see in figure 36, each plot (40) is connected electrically to a control connection box (41) of the distributed along the transport circuit, without discarding the possibility that some or some plots (40) are occupying more of a transport module (5) (physically speaking) or just a partial section thereof, and in which each junction box of control (41) is connected on the one hand to a transmission cable of power (42) and, on the other hand, to a data transmission cable (43).

The details, the shapes, the dimensions and other accessory elements, as well as the materials used in the manufacture of the transport system of the invention may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention nor of the scope defined by the claims included in continuation.
