Abstract

Novelty: method and system for the production of meshes manufactured with variably-displaced longitudinal and traverse wires or concrete rods. Manufacture stages: the longitudinal wires 1 and the traverse wires 12 are precut or supplied by a coil; the cases 2 of the longitudinal wires are set onto carriers 3 found on the pre-feeder 4; the supplier’s carrier 6 has the hooks 7 and conducts the longitudinal wires to the welding heads 10;the produced mesh 20 is received by the mesh carrier 14. All the above components (carriers, cases, hooks etc) are displaced in the direction of the traverse wire with no restrictions in order to match the longitudinal wires to be welded. The traverse wires are conducted to the welding heads for being welded along with the longitudinal ones. The machine produces meshes with openings by grouping the longitudinal wires and conducting these groups towards the welding heads, matching the position of the related mechanisms with the position of the longitudinal wires.

Description

METHOD AND SYSTEM FOR PRODUCING MESHES FROM WIRE OR BEETLE BARS WITH VARIABLE LONGITUDINAL AND TRANSVERSAL STEPS

Description

The present patent refers to a method and system for producing meshes from wires or bettobars with programmed variable longitudinal and transverse steps. The longitudinals and transverses may be coil-fed or pre-cut. The longitudinal wires are fed into trays on carriages with the carriages on a pre-feeder carriage, a feeder carriage with grippers transports them to the bonding heads and the produced mesh is picked up by a mesh carriage. The carriages with the holders of the longitudinals on the pre-feeder carriage, the grippers of the longitudinals on the feeder carriage and the welding heads are shifted in the transverse direction without restriction to match the longitudinal wires to be welded. The transverse wires are fed to the welding heads where they are welded to the longitudinal ones. The machine produces meshes with openings and meshes with different lengths of longitudinal wires, grouping the longitudinal wires into groups and feeding the groups of longitudinals to the bonding heads, adjusting the position of the related mechanisms to the position of the longitudinals.

Technical level cons

Existing welding machines show great flexibility in welding longitudinals. The pitch between the longitudinals may be variable between them along the production length of the web.

Welding machines that produce standard grids have feed mechanisms and welding heads or welding spots with pairs of electrodes at fixed distances. Their flexibility is exhausted in the production of grids with longitudinal steps multiples of a basic distance. Changing the spacing of the longitudinals requires a lot of mechanical work and is time consuming.

In another category of welding machines, the longitudinals are fed manually from pre-cut wires. Changing the distances between the longitudinals is done by manually moving the adhesive heads, guides and related mechanisms. This machine has some flexibility but low productivity due to the manual feeding of longitudinal wires.

Another class of welding machine is that where the longitudinals are fed from pre-cut wires and the movement of the welding heads, guides, and associated mechanisms is automatic and can produce grids with variable longitudinal pitches without pitch limitation. In these machines, the longitudinals are automatically fed from a longitudinals deposition table to a feeder carriage with magnetic mechanisms or mechanisms with grippers. The disadvantage of these machines is that the longitudinal feed mechanisms, in order for the automatic grippers to work, require a large number of longitudinals at the point where they are initially automatically picked up and that the longitudinals in this case can only have one diameter. An additional disadvantage is that towards the end of the production of the series of meshes produced the blanks have to be placed in the feeder manually. In addition, they cannot produce mesh with different longitudinal lengths and meshes with openings. These machines are not possible to produce small quantities of nets (1-20 pieces) due to the peculiarity of the feeding mechanism which require a large number of longitudinals.

Object of the present invention

The aim of the present invention is to present a method, which automatically produces meshes with openings with variable longitudinal pitch and in small quantities without limitations.

Purpose of the present invention

The purpose of the present invention is to present a system, which will automatically produce meshes with openings and with variable longitudinal pitch, possibly of different diameters and different lengths without limitations, with great flexibility in the production of different meshes.

Method

According to the method, the longitudinal wires (1) are deposited in a sufficient number of cases (2) on a carrier (3) which will be called a case carrier. The case carriages (3) are based on the carriage of the pre-feeder (4) and move on it independently of each other and perpendicular to the direction of the longitudinal wires, so as to receive different distances between them without restrictions.

The pre-feeder carriage (4) also moves vertically in the direction of the longitudinals from a position where the longitudinals are fed to a position on the main axial axis of the machine along which the longitudinals are transported to the bonding heads.

The feeding of the longitudinals is done along the axial (5). The pre-feed carriage (4) is moved so that a selected case carriage is in the longitudinal feed position (5). With continuous movements of the pre-feeder (4), respective longitudinal wires are deposited at specific distances that correspond to the longitudinal distances in the mesh to be produced, without limitations.

At the end of the feeding of the longitudinals (1) to the case carriages (3), the carriage of the pre-feeder (4) is moved to a suitable position to deliver the longitudinals to the carriage of the feeder (6).

The feeder carriage (6) has wire grippers (7) actuated by a motor (8), which move controllably and independently of each other and perpendicular to the longitudinal wires. The grippers (7) of the feeder carriage (6) are moved to positions corresponding to the longitudinal wires of the mesh which are to be welded.

The grippers (7) have two positions, a first position at the level of the generated mesh, so that the axial axis of the corresponding longitudinal coincides with the axial axis of the gripper (7) and a second position above the mesh so that the gripper (7) does not collide with the underlying longitudinal wire in case of a second feeding of longitudinal wires when deriving meshes with different wire lengths.

The feeder carriage (6) moves to the pre-feeder carriage (4), picks up the longitudinal wires (1) and transports them to the bonding heads (10).

The adhesive heads (10) move independently and vertically in the direction of the longitudinals and take positions corresponding to the positions of the longitudinals in the mesh being produced. They also have a gripper (11) for holding the longitudinals.

The longitudinal wires (1) are transported from the feeder carriage (6) to the gluing heads (10) where they are assembled by the grippers (11) on the gluing heads. Then the feeder carriage grippers (7) are opened, the feeder carriage (6) is moved back away from the bonding heads (10) by an appropriate length, they are reactivated, the grippers (11) of the bonding heads (10) are deactivated and advanced the longitudinal ones so that the first transverse one (12) can be welded. By repeating the advancement of longitudinals - under mesh production, cross welding in a number of cross sufficient for the first cross to be in the receiving area of the grippers (15) of the mesh carriage (14), the feeder carriage (6) is removed from the welding heads (10). Then, with continuous repetition of moving longitudinals, feeding transverses and welding transverses to longitudinals, the mesh is produced.

The produced mesh (20) is pulled by the mesh carriage (14) which has grippers (15). The grippers (14) are in number capable of transporting the produced mesh and its longitudinals during the production of the mesh. The grippers (14) move vertically and controllably in the direction of the longitudinals and take suitable positions for holding and transporting the mesh.

The grid is analyzed in groups according to the position of the longitudinals in the direction of entry to be welded to the welding heads. The longitudinals of each group of longitudinals are isosceles in a direction perpendicular to the direction of the longitudinals.

The operation of the method is illustrated by the example of the production of a mesh (21) with openings, Figure 3B, in the sense of an example. The longitudinals of the mesh under production (21) are analyzed in two groups, (22) of Fig. 3C and (23) of Fig. 3D.

The case carriages (3) on the pre-feeder (4), the grippers (7) on the feeder carriage (6) and the adhesive heads (10) are moved to positions corresponding to the longitudinals of the first group of longitudinals (22), Fig. 4A.

With continuous movements of the carriage cases of the pre-feeder (4) - feeds of longitudinals (1) the longitudinals corresponding to the group of longitudinals (22) are deposited, Fig. 4B.

The pre-feed carriage (4) transports the case carriages (3) with the longitudinals to the machine axis to receive the longitudinals from the feeder carriage (6), Fig. 4C.

The feeder carriage (6) delivers the longitudinals (22) to the grippers (11) of the gluing heads (10), the grippers of the feeder carriage (7) are deactivated, moved to a suitable length with the carriage from the gluing heads (10), activated the grippers (7) of the feeder carriage, the grippers (11) of the gluing heads (10) are deactivated and the longitudinals are advanced to a suitable length into the gluing heads. There the welding is done with the first transverse wire (12) of the grid. The next step is done by advancing through the grippers of the feeder (7) and then the mesh carriage (14) takes over the advancement of the produced mesh, Fig. 4D.

While the transverses are welded to the longitudinals, the feeder carriage (6) returns close to the pre-feeder carriage (4) and the grippers (7) of the feeder carriage (6) and the case carriages (3) of the pre-feeder carriage (4) are moved to positions corresponding to the second group of longitudinals (23). Next, the longitudinals of the second group of longitudinals are fed, Fig. 4E.

The longitudinals of the second group of longitudinals (23) are transferred by moving the pre-feeder carriage (4) towards the axial axis of the machine where they are received by the grabs (7) of the feeder carriage (6), Fig. 4F.

When receiving the longitudinals of the second group of longitudinals (23) the grippers (7), which are not going to receive longitudinal wire, with the action of the motor (8) are moved above the level of the produced mesh, so as not to collide with the other longitudinals of the first group of longitudinals (22), which are still inside the adhesive heads. Indicatively, the position of the grabs is shown in Fig. 2A, 2B.

The longitudinals of the second group of longitudinals (23) are transferred to the adhesive heads (10), Fig. 4G.

The longitudinals of the second group of longitudinals (23) are received by the grippers (11) of the adhesive heads (10), Fig. 4H.

The longitudinal wires of the second group of longitudinals (23) are cross-welded to complete the mesh, Fig. 4K.

After the welding of the transverses, the grid (21) is delivered complete, Fig. 4L.

The longitudinal wires can be of the same or different diameter.

The cross wires can be of the same or different diameter.

Both longitudinals and transverses may be windfed, aligned and cut to length, but may be pre-cut to appropriate lengths and fed to the gluing machine.

The cross wire can be welded from the top of the longitudinals, or from the bottom of the longitudinals.

For the case where the longitudinal wires are of different diameters with significant differences the welding heads may be moved perpendicular to the plane of the grid to adjust the welding electrodes to the plane of the grid wires.

System

In the system that follows, an implementation of the mentioned method is presented in the sense of an example,

The welding machine (40) consists of an appropriate number of welding heads (41) which have the ability to move in a direction perpendicular to the longitudinal ones (32) in the transverse direction.

The welding head consists of the following elements. A fixed electrode (42), mounted on a copper base (43), which is connected via a flexible conductor (44) to a socket (45).

A mobile electrode (48), mounted on a copper base (49), which is connected through a flexible conductor (50) to the corresponding socket (51).

The movable electrode and its copper base are moved by a cylinder (58), which is actuated by a valve.

The longitudinal wires pass through a guide (55) through the copper base (43) of the lower electrode.

At the entrance of the longitudinal wire to the guide (55) there is a gripper (56) activated by a cylinder (57).

The socket (45) of the fixed electrode (42) moves from a cylinder (46) perpendicular to the electrical conductor (47) and the socket of the mobile electrode (51) moves from a cylinder (52) perpendicular to the electrical conductor (53). Between the electrical conductors there is an electrical voltage capable of welding the transverse to the longitudinal. The electric voltage between the two conductors (47), (53) is produced by at least one welding transformer (60), the phases of which are connected to the supply conductors (47), (53). The number of welding transformers depends on the welding power required for simultaneous welding in more than one position. Given more transformers the number of transformers activated during welding depends on the required electrical power.

The bonding head (41) is mounted on two linear carriages (62), for its movement on linear guides (63) perpendicular to the longitudinal wires.

The welding head (41) is moved by a drive screw (64) whose rotation is converted into linear movement of the welding head (41) by means of a nut and an electric clutch (65). Turning the screw (64) only moves those welding heads (41) whose clutches (65) are activated. The drive screw (64) is driven by an electric motor (66).

The feeder carriage (70) has grippers (72), which move along the carriage (70) and perpendicular to the direction of the longitudinals (32).

The longitudinal wire passes through the input die (71) and the gripper (72). The gripper is actuated by an air cylinder (73), which holds the longitudinal (32) within the gripper (72).

The gripper (72) with the input die (71) and the air cylinder (73) are based on a guide (74) and are moved by the action of an air cylinder (75). The grippers can, with the action of the air cylinder, be in two positions, one in the supply line of the adhesive heads in the axial direction of the longitudinals (a-a') and one higher than the longitudinals (b-b') that will produce the grid.

The guide (74) is based on a plate (76) which in turn is based on two linear carriages (77), for their linear displacement vertically in the longitudinal direction.

The movement of the grippers (72) is done through the electric clutch nut (79) which, through an electrical command, engages the rotation of the drive screw (78) with the linear movement of the gripper (72). As the drive screw rotates, the grippers (72) whose clutches (79) are activated move. The drive screw is rotated by a motor (88).

The grabbers with the linear carriages, their guides, the driving screw and its motor are located on a carriage (70) which is provided at the ends of the carriage (80) and moves linearly on guides (81). The movement of the carriage is implemented with toothed wheels (82), rack (83), with the toothed wheels (82) resting on a shaft (84) driven by an electric motor (85).

The mesh carriage (90) transports the meshes being produced and also forms the step for welding the crosspieces.

It has grippers (91) which move along the carriage and perpendicular to the longitudinal wires of the grid. The gripper has the fixed caliper (92) and the movable one (93) under the action of the air cylinder (94). The two grippers (92), (93) and the air cylinder (94) are based on a joint so that the point of the grippers is in two positions, one in the area of the cross so that it can assemble it and one above the level of the meshes . This movement is implemented with an air cylinder (95). The calipers (92), (93), the air cylinder (94) and the air cylinder (95) are based on a plate (96) which in turn is based on two linear carriages (97) and are moved by the rotation of the drive screw (98). The rotation of the drive screw is converted into linear motion by means of a nut and an electric clutch (99). When the drive screw (98) is rotated, the grippers whose clutches are activated move.

The drive screw (98) is rotated by a motor (100). The mechanisms of the grabs, the driving screw and its motor are located on a carriage (90) which moves along the longitudinals on guides. An electric motor (101) rotates a shaft (102) at the ends of which two toothed wheels (103) are mounted engaging with hangers (104) on the carriage bases (105). By rotating the electric motor (101) the mesh carriage (90) is moved.

The longitudinal wires are delivered from the production unit to the pre-feeder (110) which is described below.

The wire (32) is deposited in double (111) and single (112) cases within which it is assembled by magnets. At least one double case (111) and additional single cases (112) are located on a carriage (113) which rests on linear carriages (114) and moves on linear guides (115) by a drive screw (116) via a nut and an electric clutch ( 117). The number of case carriers (113) corresponds to the number of grippers (72) of the gripper carrier (70) and the number of adhesive heads (41). The drive screw (116) is driven by an electric motor (118). The linear guides (115) of the carriages (114) are mounted on a frame (120) which is also a carriage and is mounted on linear carriages (121) on linear guides (122). The pre-feed carriage (120) is moved by chain action (123) which moves on sprockets (124). The sprockets are mounted on axles (125), (126) and driven by a motor (127) via chain transmission. The carriage is mounted on the chain via a link (128). By the action of the motor (127) the carriage (120) with the carriages (113) is moved transversely to the longitudinals from the loading position of longitudinals to the yielding area of the longitudinals on the feeder carriage. The stretchers with the cases (113) have a short length compared to the length of the longitudinals. Behind the pre-feeder carriage (120) are a number of chains (130) having a suitably shaped slot (131) flush with the case mounts (111) and (112). The chains are driven by the shaft (132) which is rotated by a transmission of sprockets (133), (134) by the shaft (126). The motor (127) simultaneously drives the carriage (120) and the chains (130) at the same linear speed.

The wires deposited on the sheaths (111), (112) and chains (130) move parallel to themselves from the feed point to the receiving area by the feeder carriage (70).

Cross wire (33) is drawn from coil (138) to wind (139) and is fed to pre-alignment (140), rotor alignment (141), passes through output and metering rollers (142), is fed to cutter (143) and then to the boat (144). The rotor (141) has a roller, aligns and advances the wire and is rotated by the motor (137). The wire is fed, measured and cut to the programmed length in the cutter (143). The vessel (144) is then opened and the wire falls by gravity to the position (145). In position (145) the air cylinder (146) is activated and pushes the gripper (147) with the magnets (148) towards the wire () which it holds. The gripper (147) with the magnets (148) is mounted on a carriage (149) which moves with a belt (150) and a motor (151) parallel to the cross wires. The wire is transported with the gripper (147) parallel to the crossbars in the position corresponding to the mesh being produced.

The flap (152) is opened by the action of the air cylinder (153) and the cross wire is guided to the position (154). With the action of the air cylinder (155), the flap (156) rotates and the wire falls from the position (154) to the position (157) where it is assembled with the beam springs (158). The pushers (159) with the action of the cylinder (160) push the wire from the position (157) towards the welding heads (41) and specifically on the lower welding electrodes (42), where the wire is assembled by the magnets.

The longitudinal wire (32) is drawn from a coil (165) on a winder (166), guided to the straightening machine and then to the boat (167) through the cutter (168). The alignment machine consists of the input rollers (169), the roller rotor (170) and the output and measuring rollers (171). The rotor (170) is rotated by the motor (172).

The wire is advanced by the rotor (170), the advanced length of wire is measured and when the programmed length has been produced the cutter (168) cuts it into the vessel (167). By opening the vessel (167) the wire is deposited on a case carrier (113) with one double (111) and one single case (112). Next, the next carriage with double and single case is advanced to the position of depositing longitudinals, the new wire that has been advanced into the vessel of longitudinals is deposited with the process continuing until the production of all longitudinals is completed.

The operation of the machine is as follows:

According to the method, the longitudinals of the grid to be produced are analyzed in groups of longitudinals.

To feed a group of longitudinals the case carriages (113) with the double (111) and the single (112) gripper are moved between them by the power of the motor (118) of the screw (116) and the clutches (117), with suitable such that they correspond to the relative distances of the longitudinals between them.

The grippers (72) of the feeder carriage (70) are moved between them by the action of the motor (88), the screw (78) and the clutches (79), so as to correspond to the positions of the longitudinals in the mesh to be produced.

The adhesive heads (41) are moved between the by the action of the motor (66) of the screw (64) and the clutches (65) and take positions corresponding to the longitudinals of the mesh to be produced.

The grippers (91) of the grid carrier (90) are moved by the action of the motor (100), the screw (98) and the clutches (99) to receiving positions of the grid by holding the first cross of the grid between the longitudinal ones,

The carriage of the pre-feeder (120) with the case carriages (113) is moved by the action of the motor (127) towards the position of depositing longitudinals. By successive feedings of longitudinals and displacements of the carriage (120) the group of longitudinals is fed.

The pre-feeder carriage (120) is shifted to the yield position of the longitudinals on the feeder carriage (70).

The feeder carriage (70) is moved by the action of the motor (85) towards the pre-feeder carriage and the ends of the longitudinal wires enter the grippers (72) of the feeder carriage. The rollers (73) of the grippers (72) are activated and pick up the longitudinals, which they transport to the adhesive heads.

The longitudinal wires (32) enter the bonding heads (41) the grippers (56) on the bonding heads are activated, the feeder carriage grippers (72) are deactivated, the feeder carriage is moved back a programmed length, the grippers are activated ( 72) of the feeder carriage (70), the grippers (56) of the welding heads (41) are deactivated, the feeder carriage (70) advances the longitudinal wires to a position corresponding to the welding of the first cross. At the same time, the first transverse (33) has been produced in the transverse alignment unit and is advanced with the pushers (159) on the longitudinals within the adhesive heads (41).

By activating the rollers (58) of the adhesive heads in which there is a longitudinal, the transverse is compressed on the longitudinals, the rollers (46), (52) are activated to move the sockets (45), (51) on the supply ducts (47) , (53), the welding transformers (60) are activated and the transverse to longitudinal welding is performed.

The feed carriage (70) with the grippers (72) and the grippers (56) of the bonding heads (41) advances the longitudinal and the welded transversal by the distance of the first from the second transversal. The cross already produced is fed on the longitudinals to the welding heads and the welding of the second cross is carried out.

At the same time, the mesh carriage (90) moves and the grippers (91) of the mesh carriage are lowered by the action of the cylinder (95), closed by the action of the cylinder (94) and the mesh carriage (90) now takes over the promotion of the product under production grid, simultaneously deactivating the grippers (72) of the feeder carriage (70) and the grippers (56) of the adhesive heads (41).

By successive advancements of the mesh under production and feeds across, the first group of mesh is produced.

Simultaneously with the production of the mesh, the case carriages (113) are moved to positions corresponding to the positions of the longitudinals of the second group of longitudinals. The pre-feed carriage (120) is moved to the longitudinal feed position where the longitudinals of the second group of longitudinals are fed.

Upon completion of the feeding of the second group of longitudinals, the carriages (113) with the longitudinals are transferred to the position of receiving longitudinals from the feeder carriage (70).

Simultaneously with the feeding of longitudinals and the production of the first group of the mesh the grippers (72) of the feeder carriage (70) are shifted to positions corresponding to the longitudinals of the second group of longitudinals and the feeder carriage (70) is shifted to receive the produced longitudinals. at the end of the production of the first group of the mesh, the adhesive heads which do not have a wire are moved to positions corresponding to the longitudinals of the second group of longitudinals.

This is followed by the reception of the longitudinals from the respective grippers (72) of the feeder trolley (70) and their transfer to the adhesive heads (41). Following the procedure of the first group, the new transverses are welded to the longitudinals and the production of the mesh continues.

With continuous advancements of the groups of longitudinals, the production of the grid is completed.
