Definitions
- 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.
- 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.
- 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 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.
- 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.
- FIGS. 1A-1I 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.
- 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 in FIG. 1B.
- FIGS. 1D and 1E depict corresponding spacers to those of FIGS. 1B-1C , but including more longitudinals, as indicated.
- FIGS. 1F and 1G present spacers 2 with differing formation of the apexes.
- 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.
- 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'.
- the spacer 2 is produced from the starting mesh 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.
- a gripper 3 that is fixed and holds the product 1 along length FG.
- a second gripper 4 holds the under-formation mesh 1 on the straight section DE.
- the gripper 4 is seated upon guides 9 and with the action of a force originating for example from a cylinder 22 may transpose the section DE perpendicular relative to axis XX'.
- Carrier 8 of gripper 4 and the guides 9 upon which gripper 4 moves are seated on a plate carrier 14 which is moved on guides 30 along the length of axis XX'.
- a third gripper 6 restrains the subject-to-formation mesh 1 on the straight section BC.
- the gripper 6 is seated on carrier 16 that moves on guides 30 along the length of axis XX'.
- gripper 5 that is seated on a carrier 11 that is moved on guides 12 perpendicularly relative to axis XX', which carrier 11 is moved by a force exercised, for example, by cylinder 23.
- Gripper 5, carrier 11, guides 12 and cylinder 23 are seated on plate carrier 15 that is seated on the guides 30 and is moved parallel to axis XX'.
- An exemplary method and system operate as follows.
- the grippers 3, 4, 5, 6, 7 are located at their initial locations that correspond to straight sections FG, DE, HI, BC, JK.
- the under-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.
- the straight section DE is transposed towards the D'E' and the HI towards the H'I'.
- the intermediate section EF carries the gripper 4, the straight section DE and the carrier 14 on the guides 30 along the length of axis XX'.
- the gripper 6 the straight section BC, and the carrier 16 are transferred on guides 30 along the length of axis XX'.
- 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 in FIGS. 1A , 1F .
- 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 to FIG. 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 to FIGS. 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.
- 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.
- FIGS. 2A-2B indicate in an exemplary manner methods for production of spacers 2 from mesh, wires or rods or material of prismatic 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'.
- the starting product 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 on guides 9 so as to be movable by the action of a force perpendicular to the longitudinal direction of product XX'.
- the guides 9, after the gripper 4, are ultimately seated on guides 30 so that they may move along the length of direction XX'.
- the subsequent apex BC is restrained by a gripper 6 that is seated on carrier 16, and this carrier 16 on guides 30 so as to be movable in the direction XX'.
- grippers 5, 7 and carriers 11, 17 with the same functionality and aim, with the starting mesh 1 being positioned inside the grippers 3, 4, 5, 6, 7.
- the sum of the grippers 3, 4, 5, 6, 7 restrain the subject-to-formation material 1.
- 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 3, 4, 5, 6, 7.
- the product may be made up of identically or differently inclined sides.
- the central jaw 3 has situated both a stationary tool 41 and also a movable tool 42 that is moved by the air 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 from FIG. 3 .
- the grippers 4, 5 also each dispose a respective stationary 41 and a respective movable tool 42 which by the action of respective cylinders 40 hold the under-formation mesh 1.
- the gripper 4 is seated on respective carrier 8 that is moved by the action of respective air cylinder 22 on guides 9 perpendicular to the under-formation mesh 1.
- the guides 9 are seated on a plate carrier 14 that in turn is seated on guides 30 so as to be movable parallel to the longitudinal axis XX' of the product.
- Air cylinder 71 acts on plate carrier 14, functioning to return the plate 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 the plate carrier 14.
- the gripper 6 has the same form with the gripper 7 and is located on respective carrier 16 that is seated upon guides 30.
- the gripper 6 also has disposed a stationary 41 tool and a movable tool 42, and these by action of cylinders 40 restrain the under-formation mesh 1.
- On gripper 6 is seated a rotating bending mechanism 81, that includes the movable tool, being in this example the cylinder 31 seated on a lever and being movable by air cylinder 24.
- the air cylinder 72 acts on carrier 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 upon carrier 16.
- the sum of the grippers 3, 4, 5, 6, 7 the carriers 13, 16, 17, 8, 11 and the guides 30 mount on a plate 59 and rotating beam 60.
- the rotating beam 60 is seated on two respective axes 64 of the respective thrust bearings 61 on the frame 62 of the machine.
- the mechanism assembly of the grippers may assume two positions, one horizontal for the supply of starting mesh 1, depicted in FIG. 3 , and one rotated, at an apex at which the unloading of the produced spacer 2 occurs.
- this exemplary machine of FIG. 3 may be understood as follows. Initially, the machine is found at a horizontal position and all the grippers 3, 4, 5, 6, 7 at their initial locations after their spacers. The under-formation initial product 1 is advanced inside grippers 3, 4, 5, 6, 7. These grippers 3, 4, 5, 6, 7 squeeze the under-formation product 1 with the action of respective cylinders 40. In following, the respective air cylinders 22, 23 of grippers 4, 5 respectively, are energized. Simultaneously, with the action of cylinders 22, 23 carriers 14, 15, 16, 17 are moved. Simultaneously, respective cylinders 24, 25 of the respective rotatable bending mechanisms 81, 82 are energized for the formation of the external sides. Consideration of FIG. 2B indicates the effect. With the end of formation the air cylinders 22, 23 are deenergized and the carriers are transposed anew because of the elastic recovery.
- the gripper system rotates to the unloading position (apex) under the action of cylinders 63.
- grippers 3, 4, 5, 6, 7 are deenergized and the readied product 2 falls to a collection surface where it is received.
- the system may produce spacers 2 with manual feeding of meshes 1, or the system may be supplied with meshes 1 from a mesh storage via a suitable supply mechanism. Furthermore, the system may cooperate with a production machine for meshes 1, these produced meshes then being automatically fed and the synchronization being effected by a central control unit.
- FIGS. 2A-2B and FIG. 3 indicate in an exemplary manner systems for production of spacers 2 from mesh, wires or rods 1, which spacers 2 have inclined sections A'B', C'D', E'F', G'H', I'J', K'L' with alternating inclinations.
- the starting product 1 is restrained at location O by gripper 3 with the action of cylinders 40, and beside location O there is gripper 4 energized by another cylinder 40, that restrains the mesh 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 on guides 9 so as to be moved by the action of cylinder 22 perpendicular to the longitudinal direction XX' of product.
- the carrier 8 is seated on guides 30 via plate carrier 14 so as to be able to move along the length of direction XX'.
- a rotating bending mechanism 81 that by action of cylinder 24 bends the end section A'B' of the spacer 2.
- the cylinders 71, 72, 73, 74 act to transfer, correspondingly, the respective carriers 14, 16, 15, 17 to their respective starting locations, as they do not typically exert any significant force on the carriers during the duration of formation.
- the entire gripper mechanism assembly is advantageously supported on a rotating beam 60, and this rotating beam in turn is supported upon two bearings 61 in a metallic construction frame 62.
- This rotating beam 60 rotates by the action of two cylinders 63, taking two positions, one horizontal for supply of the starting mesh 1 and one apex position for the unloading of the formed product 2.
- the starting mesh 1 is positioned symmetrically in the jaws 3, 4, 5, 6, 7 and these jaws 3, 4, 5, 6, 7 are located at the appropriate positions along axis XX' by the action of cylinders 71, 72, 73, 74.
- the grippers 3, 4, 5, 6, 7 restrain the subject-to-formation mesh 1, cylinders 22, 23 are energized, and the starting mesh 1 is formed into the spacer 2, with the carriers 14, 15, 16, 17 being pulled by the inclined sections C'D', E'F', G'H', I'J' of the product 2.
- the rotating bending mechanisms 81, 82 bend the end sections A'B', K'L' of the spacer 2 to a desired angle.
- the action of the deformation forces of cylinders 22, 23 of plate carriers 14, 15, and the formed product 2 undergoes elastic recovery and takes its final form.
- the entire gripper system rotates to an apex location by the action of cylinders 63, and the restraining cylinders 40 of all the grippers are deenergized to deliver the formed spacer 2.
- 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.
