Description

Technical Field

[0001] The invention relates to the technical field of steel mesh processing, in particular to a transverse steel wire feeding device. Background Art

[0002] ALC board, or autoclaved lightweight concrete board, is a porous concrete formed board made of fly ash (or silica sand), cement, lime, etc. as the main raw materials, reinforced with a steel mesh cage that has been treated with rust removal and anti-corrosion, and cured with high-pressure steam. The existing production method of the steel mesh cage of ALC board is generally to weld the steel mesh first, and then use multiple mesh clips to connect two steel meshes into a steel mesh cage. There are the following problems: 1. The steel meshes are only connected by mesh clips, and the existing mesh clips are mostly made of plastic, resulting in a weak connection between the steel meshes, affecting the overall strength of the steel mesh cage, and thus affecting the performance of the ALC board; 2. The use of mesh clips to assemble the steel mesh cage requires more manual participation, which affects production efficiency and has high labor costs.

[0003] In response to the above problems, the applicant proposed a steel mesh cage structure, in which the length of several transverse steel bars of each of the two steel meshes exceeds the width of the steel mesh, and the excess part is bent and processed into a bent part and then welded together one by one, so that the two steel meshes can be rigidly connected, and the bent part can be closed to form a clamping hole for the steel bar to be inserted, which can completely replace the mesh clamp and reduce labor costs. However, the transverse wire feeding device of the existing steel mesh production line can only convey transverse steel bars of uniform length, and it is difficult to meet the conveying requirements of transverse steel bars of two or more lengths. This problem has yet to be solved. Summary of the invention

[0004] The object of the present invention is to overcome the deficiencies existing in the above-mentioned background technology and to provide a transverse steel bar wire feeding device which can automatically convey transverse steel bars of various lengths.

DETAILED DESCRIPTION

[0028] In order to enable ordinary technicians in the field to more clearly understand the objectives, technical solutions and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] This embodiment provides a transverse steel wire feeding device for conveying steel base material and cutting it into a predetermined length. The transverse steel bars obtained after cutting are arranged crosswise with the external longitudinal steel bars 129, and then welded into a steel mesh by an external welding device. Figure 6 As shown, in the steel mesh described in this embodiment, a part of the transverse steel bars are ordinary transverse steel bars 130, whose length is basically close to the width of the steel mesh, and a part of the transverse steel bars with a longer length are transverse steel bars 131 to be bent. The length of the transverse steel bars 131 to be bent is greater than the width of the steel mesh, and both ends extend beyond the two outermost longitudinal steel bars 129 of the steel mesh by a distance. This section of the exceeding transverse steel bars serves as the bending section that finally connects the two steel meshes.

[0031] like Figures 1 to 3 As shown, the transverse steel bar wire feeding device includes a frame 100, a straightening mechanism, a sliding platform 101, a transverse wire feeding mechanism 117, a cutting mechanism 109 and a discharge frame 111. The sliding platform 101 is arranged on the frame 100, and a combined track composed of a transverse guide rail 114 and a longitudinal guide rail 113 is provided at the bottom thereof, thereby forming a cross slide structure. The sliding of the sliding platform 101 on the longitudinal guide rail 113 (parallel to the longitudinal steel bar 129) is driven by the longitudinal driving mechanism arranged on the frame 100, and the sliding of the sliding platform 101 on the transverse guide rail 114 (parallel to the transverse steel bar) is driven by the transverse driving mechanism arranged on the frame 100. As shown Figure 2 As shown, generally, since the longitudinal sliding of the sliding platform 101 usually only occurs during maintenance and fine-tuning, the longitudinal drive mechanism can be driven by a screw rod 116 and a nut driven by a hand-cranked wheel. The sliding platform 101 needs to slide horizontally frequently. In order to ensure its response speed and movement accuracy, the horizontal drive mechanism is recommended to use a servo electric cylinder 115, or other conventional linear drive components that can meet the requirements, such as a screw rod 116 and nut assembly driven by a servo motor 118.

[0032] The transverse wire feeding mechanism 117 is used to transport the steel bar mother material, and can control the length of the steel bar mother material transported each time. The transverse wire feeding mechanism 117 includes a fixed seat 112 vertically fixed on the sliding platform 101, and two groups of wire feeding components installed on the front of the fixed seat 112 for transporting the steel bar mother material. The two groups of wire feeding components are driven by a power source. Each group of wire feeding components includes two wire feeding wheels, one above and one below, and a certain gap is maintained between the two wire feeding wheels as a passage for the steel bar mother material. The edge of each wire feeding wheel is roughened or a circle of tooth grooves 127 is directly processed to increase the friction between it and the steel bar mother material, avoid slipping, and remove the oxide layer on the surface of the steel wire. Figure 5 As shown, in this embodiment, the outer ring of one of the wire feeding wheels is formed with a circumferential groove 128, which serves as a channel for the steel bar matrix, and its depth is less than the diameter of the steel bar matrix, so that the outer wall of the steel bar matrix can be exposed from the groove 128 and thus pressure is applied by the other wire feeding wheel. A plurality of guide tubes 107 can be provided on the fixing seat 112, which are in the same straight line as the channel to guide the steel bar matrix.

[0033] Of the two wire feeding wheels, the lower wire feeding wheel is a driving wheel 106 driven by a power source. Since the length of the steel bar mother material to be transported needs to be accurately controlled, a servo motor 118 is recommended as the power source. The servo motor 118 drives the driving wheels 106 of the two sets of wire feeding components to rotate synchronously through a conventional one-in and two-out speed reduction mechanism, thereby avoiding speed differences as much as possible. The upper wire feeding wheel is a driven wheel 105, which is used to apply pressure to the steel bar mother material. In order to adapt to steel bar mother materials of different thicknesses and adjust the pressure of the driven wheel 105 on the steel bar mother material at the same time, in this embodiment, the driven wheel 105 is installed on the fixed seat 112 through a vertical conventional guide structure 104. Two power components that drive the two driven wheels 105 are provided on the top of the fixed seat 112. It is recommended that the power component be a cylinder 103. When the cylinder 103 is in motion, the driven wheel 105 can slide up and down. By changing the spacing between the driven wheel 105 and the driving wheel 106, the pressure of the driven wheel 105 and the driving wheel 106 on the steel bar mother material is adjusted.

[0034] like Figure 1 to Figure 3As shown, the straightening mechanism includes three straighteners 102, of which two horizontal straighteners 102 are installed in front of the transverse wire feeding mechanism 117 through a support 108. Among the two straighteners 102, the straightener 102 at the front position can be selected as an arc or a straight line type according to the incoming position of the steel bar mother material, and the straightener 102 at the rear position is a straight line type. Another vertical straightener 102 is installed behind the transverse wire feeding mechanism 117 through a support 108, and is also a straight line type. In addition, the steel bar mother material will be slightly deformed after passing through the wire feeding wheel. The straightener 102 behind the transverse wire feeding mechanism 117 can straighten the slightly deformed area before the steel bar mother material is cut. These straighteners 102 straighten the steel bar mother material from two mutually perpendicular directions to eliminate the stress of the steel bar mother material. Furthermore, an inner winding brush for removing the oxide layer on the surface of the steel bar mother material can be installed in front of the straightening mechanism. This is a conventional component that can be directly purchased commercially and is omitted in the figure.

[0035] The cutter mechanism 109 is arranged behind the transverse wire feeding mechanism 117 through the support 108, and slides with the sliding platform 101. Its function is to cut off a section of steel bar matrix after the transverse wire feeding mechanism 117 feeds it out each time, so as to obtain transverse steel bars of a predetermined length. The cutter mechanism 109 includes a cutter 110 for cutting the steel bar matrix, and a power source that directly drives or drives the cutter 110 through a transmission member. Here, the power source can use a reduction motor 120. In this embodiment, the power source drives the cutter 110 to cut the steel bar matrix through a deflection structure (such as a cam). Obviously, other existing cutter mechanisms 109 can also be used for replacement.

[0036] The unloading rack 111 is arranged behind the cutting mechanism 109 through the support 108 and slides together with the sliding platform 101. The unloading rack 111 is installed with a supporting component and a steel bar detection component. The cut transverse steel bars are supported by the supporting component. After the steel bar detection component detects the transverse steel bars on the supporting component, the supporting component releases the transverse steel bars and sends them to the welding device by the unloading rack 111.

[0037] like Figure 4As shown, the unloading rack 111 includes a main body 121, and a guide part 123 cantilevered from the main body 121 to the welding device, and the guide part 123 is used to guide the cut transverse steel bars to fall onto the welding device, so as to be arranged crosswise with the longitudinal steel bars 129. In this embodiment, the guide part 123 is a plurality of guide plates with beveled or arc-shaped edges on the top, which are kept at a certain distance from each other. The supporting assembly includes a rotating shaft 126 passing through each guide plate, three supporting claws 122 fixedly mounted on the rotating shaft 126, and a power component (it is recommended to use a cylinder 103) that drives the rotating shaft 126 to rotate through a short connecting rod 119 to realize the swing of the supporting claws 122. The supporting claws 122 are provided with magnets for adsorbing the transverse steel bars. When the supporting claw 122 swings upward to the limit position, the supporting claw 122 protrudes from the top edge of the guide plate and can receive the cut transverse steel bar. When the supporting claw 122 swings downward to the limit position, the supporting claw 122 is lower than the top edge of the guide plate, and the transverse steel bar is blocked by the guide plate and detaches from the magnet of the supporting claw 122. The supporting claw 122 releases the transverse steel bar it receives, and the transverse steel bar slides down along the top edge of the guide plate to the welding device. In order to prevent the transverse steel bar from falling, the overhanging end of the supporting claw 122 can be bent at a certain angle, but this bend should not affect the release of the transverse steel bar.

[0038] The steel bar detection assembly includes a photoelectric sensor 124 for directly detecting the transverse steel bars, or Figure 4 As shown, it includes a detection block 125 triggered by the transverse steel bar and a photoelectric sensor 124 triggered by the detection block 125. The detection block 125 can adopt a rotatable structure similar to a tooth plate. When the transverse steel bar falls on the supporting claw 122, the detection block 125 will rotate after being pressed down or touched by the transverse steel bar, and the detection light of the photoelectric sensor 124 will change from being blocked to passing through the teeth, so that the rotation of the detection block 125 can be detected. The function of the steel bar detection component in this embodiment is to detect whether the transverse steel bar falls on the supporting claw 122. Therefore, in addition to the above structure, an existing detection module that can realize this function can also be selected for replacement.

[0039] Obviously, the above-mentioned electrical components such as the air cylinder 103, the photoelectric sensor 124, the servo motor 118, the servo electric cylinder 115, the reduction motor 120, etc. are all electrically connected to the control machine, and the control machine controls the operation of each device through these electrical components.

[0040] The working principle of this embodiment is: the servo motor 118 drives the wire feeding wheel of the transverse wire feeding mechanism 117 to rotate, and uses friction to push the steel bar mother material to move horizontally by a predetermined distance. The end of the steel bar mother material passes through the cutter mechanism 109 and is suspended above the supporting claw 122 of the unloading rack 111. In this process, the steel bar mother material is straightened by the straightening mechanism, and the oxide layer on the surface is removed by the inner brush and the wire feeding wheel. Then the reduction motor 120 of the cutter mechanism 109 drives the cutter 110 to cut off the extended steel bar mother material to obtain a transverse steel bar of a predetermined length. When the transverse steel bar falls, it is received by the supporting claw 122. When the photoelectric sensor 124 detects that there is a transverse steel bar on the supporting claw 122, the cylinder 103 drives the rotating shaft 126 to rotate to make the supporting claw 122 swing down, release the transverse steel bar, and the transverse steel bar falls along the guide plate and is sent to the external welding device, arranged orthogonally with the longitudinal steel bar 129, and then welding can be carried out.

[0041] Among these transverse steel bars, there are common transverse steel bars 130 whose length is close to the transverse width of the steel mesh, and there are also transverse steel bars 131 to be bent whose length is greater than the transverse width of the steel mesh. Usually, a transverse steel bar 131 to be bent is arranged every several common transverse steel bars 130, or as Figure 6 The ordinary transverse steel bars 130 and the transverse steel bars to be bent 131 are arranged alternately. In order to center these transverse steel bars, the servo electric cylinder 115 drives the sliding platform 101 to move, and the sliding platform 101 moves laterally with the transverse wire feeding mechanism 117, the cutting mechanism 109 and the unloading frame 111, so that the midpoints of all the transverse steel bars falling on the welding device are basically located on the same straight line.

[0042] Since the transverse wire feeding mechanism 117 can control the length of the wire fed each time, the present invention can also be transformed into another embodiment, that is, the transverse wire feeding mechanism 117 and the straightening mechanism are fixed on the frame 100, and the cutter mechanism 109 and the discharge rack 111 are installed on the sliding platform 101. The sliding platform 101 adjusts the positions of the cutter mechanism 109 and the discharge rack 111 according to the required length of the transverse steel bars. In this way, transverse steel bars of different lengths can be cut, and the midpoints of all the transverse steel bars falling onto the welding device are basically located on the same straight line.

[0043] The above is only a preferred embodiment of the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
