Description
- The present invention relates to a method and system for the production of spacers 2 from wires, rods, or materials of diverse prismatic cross section; as well as meshes of wire, or concrete-reinforcing rods, or tubes, or material of prismatic cross section. Such spacers 2 are placed inside wooden or metallic molds so as to define the location of the reinforcement of the concrete plates. These spacer meshes are produced from
initial mesh 1 that may be produced at a mesh welder. The development of such mesh into spacers occurs as follows. The initial mesh is situated along its longitudinal direction in a machine including grippers seated on carriers so as to be freely movable along this longitudinal direction of the product. However, a central gripper is stationary, whereas every second gripper may be moved also perpendicular to the longitudinal direction by the action of a cylinder. With the action of these cylinders, the starting product is deformed, and the carriers of the grippers are subjected to relocation as a result of the pull of the longitudinal wires of the starting product as the final product is formed. - The usual practice in production of spacers is their formation at presses with the use of suitable tools. An initial level mesh is introduced into a machine that has disposed both stationary and movable deformation tools, and where the movable deformation tools may be moved by pneumatic or hydraulic cylinders so that by their action the mesh is formed in the desired shape or form. In another approach, prior
US-3,722,254A disclosed a material forming apparatus with plural forming heads and a single motor acting through a drive chain system. A linkage system constrained the material forming heads in parallel, equal-space relationship relative to each other, and since all of the material forming heads were connected to each other by that linkage system, it was only necessary to connect the chains to the outermost material forming heads. Thus,US-3,722,254A necessitated that the material forming heads are connected all together by linkage control elements for maintaining a fixed angular relationship between the material forming heads as they move relative to each other. - The above referred-to methods disadvantageously require adjustment or even changing of tools for different diameters of longitudinal wires. Furthermore, the quality of the produced product is disadvantageously affected by the elastic recovery of the longitudinal wires that, in turn, is affected negatively as a result of slipping of the wires inside these tools. The result is always a disadvantageous divergence of the dimensions of the produced spacer from the desired form.
- Advantageous solutions may be found via systems and methods that locate grippers (3,4,5,6,7) at initial locations, then place material (1) inside the grippers on an axis (XX'). By energizing the grippers to hold the material at their respective locations (BC, DE, FG, HI, JK) and then energizing respective cylinders (23,24) to transpose the respective locations (DE, HI) corresponding to the respective grippers, respectively, perpendicularly relative to the axis (XX'), the product spacer (2) is deformed. This moves respective plate carriers (14,15) parallel with the axis (XX') via the linking of respective intermediate longitudinal wires (E'F', G'H') of the product (2), and also moves respective carriers (16,17) of respective grippers parallel with the axis (XX') via the linking of respective intermediate longitudinal wires (C'D', I'J') of the product (2). A bending of respective end sides (AB, KL) of the material (1) by the action of respective bending mechanisms (81,82) seated on the respective carriers (16,17) of respective grippers, may be made either at the beginning, the duration or the end of deformation. In finishing, such systems and methods open the grippers and deliver the product spacer (2).
- According to the invention, this object is achieved by systems having the features of
patent claim 1, and by processes and methods having the features ofpatent claim 7. Advantageous configurations and further developments of the invention are evident from the dependent claims and from the description in combination with the figures of the drawings. - The systems and methods may be understood to present many advantages, especially notably in that the formation of spacers now does not depend on the diameter of the longitudinal wires. Furthermore, the adjustments of the mechanism assembly are comparatively simple, that is are only the boundaries of motion of the carriers. Additionally, the forces of deformation are small because the longitudinal wires are bent freely and are not compressed in the tools. Thus, the instant invention presents advantageous systems and methods that may produce spacers from level starting mesh, flexibly, with excellent quality and low cost.
- Aspects of systems and methods according to the present invention may be understood from the following description and from the attached drawings, wherein systems and methods are presented in an exemplary manner, and where parts which are the same or similar are provided with the same reference numeral labels.

FIG. 2A - a schematic side view at the beginning of method operations. -
FIG. 2B - a schematic side view of progress of method operations. -
FIG. 3 - a detailed perspective view of a system for production of spacers. - In following are presented descriptions of exemplary implementations of systems and methods in the sense of non-limiting examples.
- The spacers 2 are depicted in
FIGS. 1A-1I and may be of differing forms.FIG. 1A depicts a spacer 2 comprised of one wire or rod. In contrast,FIG. 1B depicts the most common type of spacer 2, that includes a longitudinal mesh with two longitudinal wires.FIG. 1C similarly depicts a spacer 2, but in a version with the transverse wires located between the longitudinal wires rather than below as depicted inFIG. 1B. FIGS. 1D and1E depict corresponding spacers to those ofFIGS. 1B-1C , but including more longitudinals, as indicated.FIGS. 1F and 1G present spacers 2 with differing formation of the apexes. Finally,FIGS. 1H and 1I present spacers with different length sides, as can be seen from side view. - A method may be understood in an exemplary sense for the production of a spacer 2 with five horizontal sections, for example as in
FIGS. 1B - 1C . It should be understood that, with the same method, there may be produced spacers with more or fewer horizontal sections. - Considering
FIGS. 1B-1C andFIG. 2B , spacer 2 includes straight sections A'B', B'C', C'D', D'E', E'F', F'G', G'H', HT, I'J', J'K' and K'L' of which B'C', D'E', F'G', H'J', and J'K' are horizontal, as depicted. The location O' coincides with the middle of the straight section F'G'. With further reference toFIG. 2A , the spacer 2 is produced from the startingmesh 1 on which may be identified the locations A, B, C, D, E, F, G, H, I, J, K, L that correspond to locations A', B', C', D', E', F', G', H', I', J', K', L' of the formed spacer 2. - At the location O of the under-
formation mesh 1 there is located a gripper 3 that is fixed and holds theproduct 1 along length FG. A second gripper 4 holds the under-formation mesh 1 on the straight section DE. The gripper 4 is seated uponguides 9 and with the action of a force originating for example from acylinder 22 may transpose the section DE perpendicular relative to axis XX'. Carrier 8 of gripper 4 and theguides 9 upon which gripper 4 moves are seated on aplate carrier 14 which is moved onguides 30 along the length of axis XX'. - A
third gripper 6 restrains the subject-to-formation mesh 1 on the straight section BC. Thegripper 6 is seated oncarrier 16 that moves onguides 30 along the length of axis XX'. On thiscarrier 16 there is seated abending mechanism 81 that rotates a tool 31 around its axis by the action of a force that originates for example from acylinder 24. - Considering the other direction along axis XX' from location O, on the straight section HI acts
gripper 5 that is seated on acarrier 11 that is moved on guides 12 perpendicularly relative to axis XX', whichcarrier 11 is moved by a force exercised, for example, bycylinder 23.Gripper 5,carrier 11, guides 12 andcylinder 23 are seated on plate carrier 15 that is seated on theguides 30 and is moved parallel to axis XX'. - On the straight section JK acts
gripper 7 seated oncarrier 17 that in turn moves onguides 30 parallel to axis XX'. On thiscarrier 17 there is seated abending mechanism 82 that rotates thetool 32 on its axis by the action of a force originating from acylinder 25. - An exemplary method and system operate as follows. The
grippers formation mesh 1 is placed on axis XX' and inside the grippers. The grippers are energized and squeeze the under-formation product at the referred-to corresponding straight sections. Subsequently there are energized therespective cylinders respective carriers 14, 15 correspondingly. The straight section DE is transposed towards the D'E' and the HI towards the H'I'. During the movement ofcarriers 8, 11 perpendicularly relative to axis XX' there are moved thecarriers carrier 14 on theguides 30 along the length of axis XX'. Simultaneously via the action of straight section CD thegripper 6, the straight section BC, and thecarrier 16 are transferred onguides 30 along the length of axis XX'. - With the completion of the action of the
cylinders mechanisms - With the retraction of the forces of
cylinders grippers - Considering
FIGS. 1F-1I , the restraining tools at the gripper may be formed at their interior side with a radius of curvature so as to correspond to the desired radius of curvature of the longitudinal wires of the spacer 2. - The method was presented in exemplary form for the products of
FIGS. 1A-1I . It should be understood that the method may be applied for the simultaneous formation of spacers 2 with either more or fewer apexes. Furthermore, while the method is advantageously applied for the production of spacers from initial product mesh, it should be understood that it may in this form also deform at least one or more wires or rods, as depicted inFIGS. 1A ,1F . - According to the method, the form of the spacer 2 depends on the tools on the grippers. With different tools a different product may be produced, such as, for example, the products of
FIGS. 1F-1G . Furthermore, with more particular reference toFIG. 1I , according to the method, it should be understood that the apexes of the spacer may have either the same or different forms in correspondence with the chosen tools on the grippers. Again with reference toFIGS. 1H-1I , according to the method, the sections on the apexes F'G', D'E', B'C', H'I', J'K' may have either equal or different lengths. - With further reference to
FIG. 1H , according to the method the intermediate sections EF and CD may be different or equal length one to the other. With the action of the forces, the carriers are moved and deform the product. - Accordingly,
FIGS. 2A-2B indicate in an exemplary manner methods for production of spacers 2 from mesh, wires or rods or material ofprismatic cross section 1, which spacers 2 include inclined sections A'B', C'D', E'F', G'H', I'J', K'L' with alternating inclinations and intermediate apexes B'C', D'E', F'G', H'I', J'K'. As explained, the startingproduct 1 is restrained at a location O by gripper 3, and an apex DE beside location O is restrained by a gripper 4 that is seated onguides 9 so as to be movable by the action of a force perpendicular to the longitudinal direction of product XX'. Theguides 9, after the gripper 4, are ultimately seated onguides 30 so that they may move along the length of direction XX'. The subsequent apex BC is restrained by agripper 6 that is seated oncarrier 16, and thiscarrier 16 onguides 30 so as to be movable in the direction XX'. On thegripper 6 there is seated arotating bending mechanism 81 that bends the last section A'B' of the spacer 2. Advantageously, from the other side of location O there aregrippers carriers mesh 1 being positioned inside thegrippers grippers formation material 1. By the action ofcylinders grippers 4, 5 the startingmaterial 1 is deformed into the form of a spacer 2, with thecarriers rotating bending mechanisms respective cylinders carriers 14, 15 and the formed product 2 may undergo elastic recovery and thus assume its final form. At the end, thegrippers - In following to the explanation of the immediately preceding paragraph, and with reference to FIGS. IF - 1I, it should be understood that optionally, the form of the product at the apexes may be of any form, in conjunction with the form of the restraining tools of the
grippers - Considering
FIG. 2A andFIG. 3 , the central jaw 3 has situated both astationary tool 41 and also amovable tool 42 that is moved by theair cylinder 40. The gripper 3 has a slot disposed so that it may enter inside the under-production mesh 1 in a manner that may be understood fromFIG. 3 . - As may be further understood from
FIG. 2A andFIG. 3 , thegrippers 4, 5 also each dispose a respective stationary 41 and a respectivemovable tool 42 which by the action ofrespective cylinders 40 hold the under-formation mesh 1. The gripper 4 is seated on respective carrier 8 that is moved by the action ofrespective air cylinder 22 onguides 9 perpendicular to the under-formation mesh 1. Theguides 9 are seated on aplate carrier 14 that in turn is seated onguides 30 so as to be movable parallel to the longitudinal axis XX' of the product. Air cylinder 71 acts onplate carrier 14, functioning to return theplate carrier 14 to its starting position for the start of formation, while during the duration of formation the cylinder 71 does not exert forces on theplate carrier 14. - Considering
FIG. 2A andFIG. 3 further, thegripper 6 has the same form with thegripper 7 and is located onrespective carrier 16 that is seated upon guides 30. Thegripper 6 also has disposed a stationary 41 tool and amovable tool 42, and these by action ofcylinders 40 restrain the under-formation mesh 1. Ongripper 6 is seated arotating bending mechanism 81, that includes the movable tool, being in this example the cylinder 31 seated on a lever and being movable byair cylinder 24. As shown, theair cylinder 72 acts oncarrier 16 so as to transport it to its initial location for the start of deformation, while during the duration of deformation it does not exert forces uponcarrier 16. - On the other side of location O and symmetrically relative to the machine axis XX', there are
respective grippers grippers 4, 6, and there is also abending mechanism 82 in correspondence to bendingmechanism 81. - As depicted in detail in
FIG. 3 , the sum of thegrippers carriers guides 30 mount on aplate 59 androtating beam 60. Therotating beam 60 is seated on tworespective axes 64 of therespective thrust bearings 61 on theframe 62 of the machine. With the action ofair cylinders 63 the mechanism assembly of the grippers may assume two positions, one horizontal for the supply of startingmesh 1, depicted inFIG. 3 , and one rotated, at an apex at which the unloading of the produced spacer 2 occurs. - The function of this exemplary machine of
FIG. 3 may be understood as follows. Initially, the machine is found at a horizontal position and all thegrippers initial product 1 is advanced insidegrippers grippers formation product 1 with the action ofrespective cylinders 40. In following, therespective air cylinders grippers 4, 5 respectively, are energized. Simultaneously, with the action ofcylinders carriers respective cylinders rotatable bending mechanisms FIG. 2B indicates the effect. With the end of formation theair cylinders - Then in progress toward finishing, the gripper system rotates to the unloading position (apex) under the action of
cylinders 63. At theunloading position grippers - It should be understood by the above discussion that the system may produce spacers 2 with manual feeding of
meshes 1, or the system may be supplied withmeshes 1 from a mesh storage via a suitable supply mechanism. Furthermore, the system may cooperate with a production machine formeshes 1, these produced meshes then being automatically fed and the synchronization being effected by a central control unit. - Accordingly,
FIGS. 2A-2B andFIG. 3 indicate in an exemplary manner systems for production of spacers 2 from mesh, wires orrods 1, which spacers 2 have inclined sections A'B', C'D', E'F', G'H', I'J', K'L' with alternating inclinations. The startingproduct 1 is restrained at location O by gripper 3 with the action ofcylinders 40, and beside location O there is gripper 4 energized by anothercylinder 40, that restrains themesh 1 at a starting location that, after the formation corresponds to the next neighboring apex D'E' of the spacer 2. The gripper 4 is seated on a respective carrier 8 which is ultimately seated onguides 9 so as to be moved by the action ofcylinder 22 perpendicular to the longitudinal direction XX' of product. The carrier 8 is seated onguides 30 viaplate carrier 14 so as to be able to move along the length of direction XX'. In following, in the same direction there is ajaw 6 that also restrains the startingmesh 1 at a location BC that corresponds to the next apex B'C', with thegripper 6 being energized bycylinders 40 and thegripper 6 being seated oncarrier 16 and thus on guides 30 so as to be able to be moved parallel to the direction XX'. On thegripper 6 there is seated arotating bending mechanism 81 that by action ofcylinder 24 bends the end section A'B' of the spacer 2. On the other side of location O there exist thesame grippers same carriers cylinders respective carriers rotating beam 60, and this rotating beam in turn is supported upon twobearings 61 in ametallic construction frame 62. Thisrotating beam 60 rotates by the action of twocylinders 63, taking two positions, one horizontal for supply of the startingmesh 1 and one apex position for the unloading of the formed product 2. The startingmesh 1 is positioned symmetrically in thejaws jaws cylinders grippers formation mesh 1,cylinders starting mesh 1 is formed into the spacer 2, with thecarriers rotating bending mechanisms cylinders plate carriers 14, 15, and the formed product 2 undergoes elastic recovery and takes its final form. To finish, the entire gripper system rotates to an apex location by the action ofcylinders 63, and the restrainingcylinders 40 of all the grippers are deenergized to deliver the formed spacer 2. - In following to the explanation of the immediately preceding paragraph, it should be understood that optionally, the feeding of
meshes 1 may be made automatically by a machine for the production of mesh, or may be made automatically by a feeder. Systems according to the explanation of the immediately preceding paragraph may optionally but preferably be controlled by an electronic computer so that all the working phases occur automatically. - It should be understood in the context of the preceding discussion that the present invention is not limited in any manner to the described and drawings-depicted implementations, but may be realized in many forms and dimensions without abandoning the region of protection of the invention. For example, in implementations of the invention the materials that are used and also as well the dimensions of particular elements may be according to the demands of a particular construction. Thus, in closing, it should be noted that the invention is not limited to the abovementioned versions and exemplary working examples.
