Description

Technical Field

[0001] This invention relates to the field of workshop conveying system technology, specifically to a stepped rebar feeding module, a rebar processing production line, and processing technology. Background Technology

[0002] Steel bars are commonly used building materials in engineering construction. Their processing typically includes straightening, cutting, and bending, with conveying equipment used to move the bars to improve automation. Different processing equipment has height differences: steel bars can be easily moved from higher to lower positions by rolling; however, a stepped feeder is needed to lift the steel bars from lower to higher positions.

[0003] The stepped feeder uses an alternating stepped structure to drive the steel bars to rise step by step, but the problem of the steel bars falling off the steps often occurs. Summary of the Invention

[0004] In order to overcome the problem of "steel bars falling from the stepped feeder" in the above-mentioned background technology, the present invention provides a stepped steel bar feeding module, a steel bar processing production line and processing technology.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A stepped rebar feeding module includes a lifting assembly; the lifting assembly includes a fixed plate and a lifting plate; the top edge of the fixed plate has several first steps, and the top edge of the lifting plate has several second steps; the lifting plate is capable of lifting and lowering to drive the rebar to rise along the first steps; a strip-shaped or rod-shaped inclined pressure member is provided between the fixed plate and the lifting plate; the first bottom surface of the inclined pressure member is pressed against the rebar to reduce the probability of the rebar coming out of the overlapping groove formed by the first and second steps, and to prevent the rebar from returning; an angle sensor is provided above the fixed plate, and the angle sensor is connected to the top of the inclined pressure member; when the rebar moves along the first step, it can drive the inclined pressure member to swing; the angle sensor is used to measure the swing angle of the inclined pressure member; it also includes a storage unit and a calculation unit; the storage unit is used to store the angle data of each swing of the inclined pressure member; the calculation unit is used to count the frequency of repeated angle data to detect the position of the first or second step that has malfunctioned.

[0006] As a further optimization of the present invention, when the reinforcing bar rises or falls along the first step of different grades, it can push the inclined pressure member to swing at different angles.

[0007] As a further optimization of the present invention, the swing angle of the inclined pressure member increases as the reinforcing bar rises.

[0008] As a further optimization of the present invention, the tilt angle of the inclined pressure member is adapted to the arrangement direction of the first step.

[0009] As a further optimization of the present invention, the fixed plate is upright; the lifting plate is upright and parallel to the fixed plate; the first step and the second step correspond one-to-one, and the second step is adapted to the first step corresponding to it; both the first step and the second step are inclined.

[0010] As a further optimization of the present invention, it also includes a low-level lateral conveying component and a high-level longitudinal conveying component disposed on both sides of the lifting component.

[0011] As a further optimization of the present invention, the widths of the different first steps are all equal; the heights of the different first steps are all equal; the inclination angles of the different first steps are all equal; the widths of the different second steps are all equal; the heights of the different second steps are all equal; and the inclination angles of the different second steps are all equal.

[0012] The steel bar processing production line includes a stepped steel bar feeding module, a cross-feeding component, a low-level longitudinal conveying component, a first bending machine, and a second bending machine. Two low-level transverse conveying components are provided and located on either side of the cross-feeding component. One low-level transverse conveying component is positioned between the lifting component and the cross-feeding component, and the other low-level transverse conveying component is positioned between the low-level longitudinal conveying component and the cross-feeding component. The first bending machine is located at the end of the high-level longitudinal conveying component, and the second bending machine is located at the end of the low-level longitudinal conveying component.

[0013] As a further optimization of the present invention, when the swing angle of the inclined pressure member reaches its maximum value, the cross-feeding assembly can control the steel bar used for replenishment to roll in the direction of the lifting assembly.

[0014] The steel bar processing technology involves using a steel bar processing production line to process steel bars, and the steps include... S1. Convey the reinforcing bar, and simultaneously detect the location of the failed first step or second step based on the number of times the reinforcing bar climbs different first steps; S2. Bend the reinforcing bar.

[0015] In summary, the present invention has at least one of the following advantages: (1) The present invention adds an inclined pressure member for obliquely pressing the reinforcing bars. On the one hand, by adding an oblique pressure form, the tendency of the reinforcing bars to move towards the inside of the first V-shaped groove is enhanced, reducing the probability of the reinforcing bars coming out of the overlapping groove; on the other hand, even if the reinforcing bars come out of the overlapping groove, they can be quickly stopped (i.e., locked in the next level of the first V-shaped groove), preventing them from falling further downward and reducing the number of falling levels; on the third hand, the lifting plate can drive the stopped reinforcing bars to try to climb again and again, thereby improving the overall lifting success rate.

[0016] (2) The inclined pressure member can (partially or completely) seal the top opening of the overlapping groove, which has the effect of inhibiting the problem of the reinforcing bar slipping or popping out from the overlapping groove.

[0017] (3) An angle sensor is used to collect data on the swing angle of the inclined pressure component; the calculation unit is used to count the frequency of repeated angle data to detect the location of the first or second step of the functional failure (i.e., to detect which specific first / second step is faulty). In traditional technology, machine vision is often used to detect defects, but wear defects and fit defects are relatively microscopic and difficult to collect data through cameras; therefore, the present invention has more reliable detection accuracy and more convenient operation.

[0018] (4) The present invention can also assess the level of failure: for example, if the amount of data at a certain angle exceeds 40% of the data at other angles, it can be determined as a severe failure, and the operator and maintenance personnel need to be notified through an alarm system such as a loudspeaker; after the maintenance personnel perform timely maintenance, the loss of the present invention due to ineffective operation can be reduced.

[0019] (5) The guide bar guides the lifting plate and improves the transmission stability. On the other hand, it supports the inclined pressure piece to form a material feeding gap so that the steel bars can be smoothly transported to the bottom of the inclined pressure piece, instead of being jammed by the intersecting inclined pressure piece and the conveyor chain.

[0020] (6) The cross-feeding component works in conjunction with the inclined pressure component to achieve rapid replenishment of reinforcing bars. When the reinforcing bars are lifted to the top of the fixed plate, the single swing angle of the inclined pressure component reaches its maximum value (this data can be obtained conveniently and intuitively). At this time, the cross-feeding component can feed the lifting component to replenish the reinforcing bars, reduce the time interval of reinforcing bar feeding, improve processing efficiency, and avoid the problem of two or more reinforcing bars colliding with each other and getting tangled in a bundle at the bottom of the lifting component, making it difficult to be lifted by the first step.

Low-position lateral conveying component b. Detailed Implementation

[0023] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows: Reference Figure 1 and Figure 2 This embodiment provides a stepped rebar feeding module, including a low-level transverse conveying component 1, a high-level longitudinal conveying component 2, and a lifting component 3. The low-level transverse conveying component 1 and the high-level longitudinal conveying component 2 are respectively disposed on both sides of the lifting component 3. The lower end of the lifting component 3 is adapted to the end position of the low-level transverse conveying component 1, and the higher end of the lifting component 3 is adapted to the position of the high-level longitudinal conveying component 2. The lifting component 3 is used to lift the rebar 9 on the low-level transverse conveying component 1 and transport it to the position of the high-level longitudinal conveying component 2.

[0024] Reference Figure 2The low-position lateral conveying assembly 1 includes a first crossbar 11, a conveyor chain 12, a first sprocket 13, a second sprocket 14, and a first motor. The first sprocket 13 and the second sprocket 14 are rotatably mounted at both ends of the first crossbar 11 (e.g., via a shaft and bearing). The conveyor chain 12 is annular and vertically covers the outer periphery of the first crossbar 11, with both ends of the conveyor chain 12 adapted to mesh with the first sprocket 13 and the second sprocket 14, respectively. The end of the low-position lateral conveying assembly 1 points towards the lifting assembly 3. The housing of the first motor is fixedly connected to the first crossbar 11 by bolts. The first output shaft of the first motor is coaxial and fixedly connected (e.g., by bolts) with the shaft inserted at the center of the second sprocket 14. The second sprocket 14 is fixedly connected (e.g., by bolts) to the shaft inserted at its center. The first motor can drive the second sprocket 14 to rotate, thereby driving the conveyor chain 12 and the first sprocket 13 to rotate, thus driving the steel bar 9 pressed onto the conveyor chain 12 to move in the direction of the lifting assembly 3. The first sprocket 13 is installed at the end of the first crossbar 11 near the lifting assembly 3, and the second sprocket 14 is installed at the end of the first crossbar 11 away from the lifting assembly 3, thereby avoiding interference between the first motor and the lifting assembly 3.

[0025] Reference Figure 2 The conveyor chain 12 above the upper surface of the first crossbar 11 is used to transport the reinforcing bar 9; the conveyor chain 12 above the upper surface of the first crossbar 11 is arranged perpendicularly to the reinforcing bar 9 being transported by it.

[0026] Reference Figure 2 The first crossbar 11 is supported by the first leg 111. The bottom end of the first leg 111 is fixedly connected to the floor of the processing workshop (e.g., by anchoring), and the top end of the side wall of the first leg 111 is fixedly connected to the side wall of the first crossbar 11 (e.g., by bolting or by welding), so as to make way for the conveyor chain 12 at the bottom of the first crossbar 11.

[0027] Reference Figure 2 and Figure 7The high-level longitudinal conveying assembly 2 includes a support frame 21, a first conveying roller 22, and a second motor 23. The first conveying roller 22 is rotatably mounted laterally inside the support frame 21 (e.g., via a bearing connection). The circumferential surface of the first conveying roller 22 has a first annular groove for holding the reinforcing bar 9. The housing of the second motor 23 is located on the outer wall of the support frame 21 (e.g., via bolts). The second output shaft of the second motor 23 is coaxially arranged with and fixedly connected to the first conveying roller 22 (e.g., the second output shaft is inserted into the center hole on the end face of the first conveying roller 22 and fixedly connected with bolts). The axial direction of the first conveying roller 22 is arranged laterally (i.e., along the shorter edge of the processing workshop). Several first conveying rollers 22 are arranged in a linear array along the longitudinal direction (i.e., along the longer edge of the processing workshop). The support frame 21 is arranged longitudinally to realize the conveying of the reinforcing bar 9.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The lifting assembly 3 includes a fixed plate 31 and a lifting plate 32. The top edge of the fixed plate 31 has several first steps 311 (the first steps 311 are arranged at an angle to form a first V-groove 3110 structure; the lowest first step 311 is located at the end of the low-position transverse conveying assembly 1 and at adapter height, while the highest first step 311 is located diagonally above the high-position longitudinal conveying assembly 2). The top edge of the lifting plate 32 has several second steps 321 (the second steps 321 are arranged at an angle to form a second V-groove 3210 structure, and the angle of the second steps 321 is adapted to the angle of the first steps 311). The first steps 311 are arranged in a continuous stepped pattern, and the second steps 321 are also arranged in a continuous stepped pattern. The first steps 311 and the second steps 321 correspond one-to-one (i.e., the second steps 321 and the first steps 311 of the same level correspond to each other), and the second steps 321 and their corresponding first steps 311 (i.e., the second steps 321 and the first steps 311 of the same level) are adapted to each other.

[0029] Reference Figure 3 Since both the first step 311 and the second step 321 are inclined, the reinforcing bar 9 has a tendency to roll / slide towards the lowest position on the top surface of the first step 311 / second step 321, which will improve the locking stability of the reinforcing bar 9 and reduce the probability of the reinforcing bar 9 detaching from the first step 311 and falling downward.

[0030] Reference Figures 2-4 The lifting plate 32 can be raised and lowered (along the vertical edge of the first step 311) to drive the reinforcing bar 9 to rise and fall along the first step 311 (the purpose of the lifting plate 32 is to drive the first step 311 to rise, but if the lifting function fails, the reinforcing bar 9 will fall).

[0031] Reference Figure 4 and Figure 5 The fixed plate 31 is upright, and several fixed plates 31 are arranged parallel to each other. The lifting plate 32 is upright, and several lifting plates 32 are arranged parallel to each other. The fixed plates 31 and the lifting plates 32 are arranged parallel to each other, thereby realizing the synchronous and stable lifting of the reinforcing bars at more than 9 positions.

[0032] Reference Figure 2 , Figure 4 and Figure 5 The lifting assembly 3 also includes a support frame 33, a cam 34, a camshaft 35, a guide crossbar 36, and a linkage plate 37. The support frame 33 includes a support base and a diagonal brace 331. The support base is fixedly connected to the processing workshop floor (e.g., anchored), and the bottom end of the diagonal brace 331 is fixedly connected to the support base (e.g., by bolts). The top end of the side wall of the diagonal brace 331 is fixedly connected to the fixing plate 31 (the edge opposite to the first step 311) (e.g., by bolts).

[0033] Reference Figure 2 , Figure 4 and Figure 6 The cam 34 is located below the lifting plate 32. The side wall of the lifting plate 32 is connected to a rotatable friction-reducing wheel 323 (for example, connected by a bearing and a shaft). The friction-reducing wheel 323 is pressed against the top surface of the cam 34. During the eccentric rotation of the cam 34, the friction-reducing wheel 323 can roll relative to the circumference of the cam 34, thereby driving the lifting plate 32 to rise and fall smoothly.

[0034] Reference Figure 4 and Figure 7 The lifting plate 32 is positioned above the horizontally placed camshaft 35. The camshaft 35 is inserted into and rotatably connected to the fixed plate 31 (e.g., via a bearing). The camshaft 35 is inserted into and fixed to the cam 34 (e.g., via bolts). The end of the camshaft 35 is coaxially arranged and fixedly connected to the third output shaft of the third motor 351 (e.g., via bolts). The housing of the third motor 351 is fixedly installed on the outer wall of the fixed plate 31 at the end of the lifting assembly 3 (e.g., via bolts). The third motor 351 drives the camshaft 35 to rotate, thereby driving the cam 34 to rotate, thus realizing the lifting movement of the lifting plate 32.

[0035] Reference Figure 4 and Figure 6The guide crossbar 36 is inserted and fixed to the fixed plate 31 (e.g., by bolts). The lifting plate 32 has a first slotted hole 322 adapted to the guide crossbar 36, and the guide crossbar 36 is inserted into the first slotted hole 322. During the lifting process of the lifting plate 32, the first slotted hole 322 rises and falls synchronously around the guide crossbar 36 to avoid hindering the movement of the lifting plate 32. The guide crossbar 36 and the first slotted hole 322 cooperate with each other to improve the movement stability of the lifting plate 32.

[0036] Reference Figure 4 and Figure 5 Several lifting plates 32 are fixedly connected by a linkage plate 37 to achieve synchronous lifting, thereby reducing the number of cams 34 required (for example, cams 34 are installed under odd-numbered lifting plates 32, while cams 34 are not installed under even-numbered lifting plates 32). The lifting plates 32 and the linkage plate 37 are fixedly connected in an E-shape (for example, by vertical fixing with bolts). See reference... Figure 2 The fixed plate 31 has a rectangular notch 313 adapted to the linkage plate 37, for accommodating the linkage plate 37 and enabling the linkage plate 37 to move up and down smoothly. (See reference...) Figure 2 , Figure 4 and Figure 5 The linkage plate 37 and the back support diagonal rod are slidably connected by a ball linear guide pair 371, thereby improving the stability of the lifting of the linkage plate 37 and increasing the load-bearing capacity of the lifting plate 32 (to resist the vibration caused by the impact between the lifting plate 32 and the steel bar 9).

[0037] Reference Figure 7 The fixed plate 31 and the lifting plate 32 are arranged along the transverse direction (i.e., the shorter edge direction of the processing workshop), and the camshaft 35 is arranged along the longitudinal direction (i.e., the longer edge direction of the processing workshop).

[0038] Reference Figure 8 Under the action of the lifting plate 32 (reciprocating lifting push), the steel bar 9 moves along the edge of the first step 311, and the moving path 90 is stepped, and the moving path 90 is adapted to the edge of the first step 311.

[0039] Reference Figure 7 , Figure 9 and Figure 10A strip-shaped or rod-shaped inclined pressure member 38 is provided between the fixed plate 31 and the lifting plate 32. The inclined pressure member 38 is inclined, and the inclination direction of the inclined pressure member 38 is adapted to the inclination direction of the first step 311. The bottom of the inclined pressure member 38 is provided with a first bottom surface 381, which is straight. Under the weight of the inclined pressure member 38 itself, the first bottom surface 381 presses against the reinforcing bar 9 (top surface), which is used to reduce the probability of the reinforcing bar 9 falling out of the overlapping groove 31100 formed by the first step 311 and the second step 321, and to prevent the reinforcing bar 9 from falling back (to wedge the fallen reinforcing bar 9 in the next level overlapping groove 31100, thereby preventing the reinforcing bar 9 from falling further down).

[0040] The inclined pressure member 38 is a (straight) strip plate or (straight) round rod structure.

[0041] Reference Figure 3 The overlapping groove 31100 is the overlapping part of the first V-shaped groove 3110 and the second V-shaped groove 3210, and is in the shape of an inclined V.

[0042] Reference Figure 3 , Figure 9 and Figure 10 The inclined pressure member 38 applies an inclined pressure to the reinforcing bar 9, thereby causing the reinforcing bar 9 to tend to move / roll towards the bottom tip of the overlapping groove 31100. In addition, the inclined pressure member 38 can (partially or completely) block the top opening of the overlapping groove 31100, thereby reducing the probability of the reinforcing bar 9 detaching from the overlapping groove 31100 (detachment includes slipping and popping).

[0043] The specific reasons why rebar 9 slipped out of the overlapping groove 31100 are as follows: (Refer to...) Figure 10 To achieve single-bar feeding, the width of the flat bottom surface of a single overlapping groove 31100 typically needs to be adapted to the diameter of a single reinforcing bar 9 (i.e., the flat bottom surface of the overlapping groove 31100 is relatively narrow), so that a single overlapping groove 31100 can only support a single reinforcing bar 9; excess reinforcing bars 9 will slip off and cannot be stably held in the overlapping groove 31100. Combined with... Figure 11 During operation, the reinforcing bar 9 will wear down the first step 311 / second step 321, especially at its external corners where the wear rate is the fastest. This will reduce the width of the area that the flat bottom surface of the overlapping groove 31100 can support the reinforcing bar 9 (the width of this area is reduced from Q1 to Q2). Even a single reinforcing bar 9 can easily slip off the overlapping groove 31100, causing the feeding function to fail. In this case, the reinforcing bar 9 will slip from the upper overlapping groove 31100 to the lower overlapping groove 31100. As a result, the reinforcing bar 9 will always be stuck at the position of the first step 311 and will not be able to rise completely to the next step.

[0044] The reason why rebar 9 popped out of the overlapping groove 31100 is as follows: (Refer to...) Figure 3The vertical edges of the first step 311 / second step 321 are easily damaged by the impact of the reinforcing bar 9. To increase the anchoring force, some of the reinforcing bars 9 have protrusions on their surfaces. When the reinforcing bar 9 is lifted, the protrusions are easily caught with the gaps and forcibly disengaged, causing the reinforcing bar 9 to bounce and easily pop out of the overlapping groove 31100 and fall (in this case, it is difficult for the next first step 311 to re-catch the reinforcing bar 9, so the reinforcing bar 9 will most likely fall onto the lower transverse conveying assembly 1).

[0045] Reference Figure 9 The inclined pressure member 38 applies a stopping force to the sliding steel bar 9, so the steel bar 9 is difficult to continuously slide down to the lower horizontal conveying component 1, but is limited to the position of the next first step 311. After that, when the lifting plate 32 is raised and lowered, it can try to drive the steel bar 9 (at this position) to rise again, without having to raise the steel bar 9 that has slid down to the lower horizontal conveying component 1 from the bottom up step by step, thereby improving the success rate of conveying (i.e. lifting).

[0046] Reference Figure 9 When the inclined pressure member 38 applies a stopping force to the bouncing steel bar 9, the steel bar 9 is limited to the position of the first step 311 of the current level or the first step 311 of the next level, instead of falling directly onto the low-level transverse conveying component 1. Afterwards, when the lifting plate 32 is raised and lowered, it can try to drive the steel bar 9 (at this position) to rise again, without having to raise the steel bar 9 that has slipped onto the low-level transverse conveying component 1 from the bottom up step by step, thereby improving the success rate of conveying (i.e., lifting).

[0047] Combination Figure 9 and Figure 11 In this invention, because the inclined pressure member 38 applies pressure to the reinforcing bar 9, the pressure between the reinforcing bar 9 and the external corner of the first step 311 / second step 321 increases, which further accelerates the wear rate of the external corner and makes the feeding function failure more frequent. The production of the reinforcing bar 9 is an automated operation, making it difficult to assign a dedicated person to visually monitor the feeding function failure next to the lifting component 3; therefore, this invention provides a solution that enables automated monitoring (details below).

[0048] Reference Figure 12All first steps 311 have the same shape, size, and inclination angle (i.e., all first steps 311 are rectangular plates; the height H1 of all first steps 311 of different grades is equal, the width M1 of all first steps 311 of different grades is equal, and the inclination angle r1 of all first steps 311 of different grades is equal). All second steps 321 have the same shape, size, and inclination angle (i.e., all second steps 321 of different grades are rectangular plates; the height H2 of all second steps 321 of different grades is equal, the width M2 of all second steps 321 of different grades is equal, and the inclination angle r2 of all second steps 321 of different grades is equal); the inclination angle r1 of the first step 311 is equal to the inclination angle r2 of the second step 321; this allows the inclined pressure member 38 to swing at different angles when the reinforcing bar 9 rises or falls along the first steps 311 of different grades.

[0049] Reference Figure 13 An angle sensor 39 is installed above the fixed plate 31 (top), and the angle sensor 39 is connected to the top of the inclined pressure member 38 (the top of the inclined pressure member 38 is the rotation center, and the bottom is the swing end). When the reinforcing bar 9 moves along the first step 311 (whether rising or falling), it can drive the inclined pressure member 38 to swing (when the reinforcing bar 9 rises, it pushes the swing end of the inclined pressure member 38 to rise; when the reinforcing bar 9 falls, the supporting force of the reinforcing bar 9 on the inclined pressure member 38 decreases, and the weight of the inclined pressure member 38 itself drives the swing end to fall). The angle sensor 39 is used to measure the swing angle of the inclined pressure member 38. The angle sensor 39 monitors the angle of each swing of the inclined pressure member 38 in real time, in units of the number of swings. The accuracy of the swing angle is 0.2 degrees.

[0050] It also includes a storage unit (e.g., a memory) and a processing unit (e.g., a central processing unit); the storage unit is used to store the angle data of each swing of the inclined pressure member 38. The angle sensor 39 is used to convert the collected swing angle into angle data (electrical signal) and input it into the storage unit. The processing unit is used to count the frequency of repeated angle data to detect the position of the first step 311 or the second step 321 where the (lifting) function has failed (i.e., to detect which specific first step 311 / second step 321 has failed).

[0051] For example: the first step 311 has four levels (counted from bottom to top; the second step 321 also has four levels); when the reinforcing bar 9 rises along the vertical edge of the first step 311, the swing angle of the inclined pressure member 38 is 6.2 degrees; when the reinforcing bar 9 rises along the vertical edge of the second step 311, the swing angle of the inclined pressure member 38 is 10.2 degrees; when the reinforcing bar 9 rises along the vertical edge of the third step 311, the swing angle of the inclined pressure member 38 is 14.2 degrees; when the reinforcing bar 9 rises along the vertical edge of the fourth step 311, the swing angle of the inclined pressure member 38 is 18.2 degrees. After the lifting assembly 3 has been running for 3 hours, statistical data shows that the 6.2-degree data appeared a total of 2160 times, the 10.2-degree data appeared a total of 3815 times, the 14.2-degree data appeared a total of 2500 times, and the 18.2-degree data appeared a total of 2160 times (refer to...). Figure 13 , Figure 14 and Figure 15 If the following is true, then it can be determined that the rebar 9 underwent a relatively large number of continuous raising and lowering operations at the second-level first step 311 position (i.e., multiple attempts to raise the rebar 9 failed each time), while the rebar 9 underwent a relatively small number of continuous raising and lowering operations at the third-level first step 311 position. In other words, the second-level first step 311 and / or the second-level second step 321 experienced a lifting function failure (caused by wear, fit defects, etc.), and the failure was relatively severe. The third-level first step 311 and / or the third-level second step 321 experienced a lifting function failure (caused by wear, fit defects), and the failure was relatively minor. Therefore, maintenance personnel need to perform maintenance work on the second-level first step 311, the second-level second step 321, the third-level first step 311, and the third-level second step 321 (e.g., replacing parts or welding repairs).

[0052] Traditional technologies often use machine vision to detect defects, but wear defects and fit defects are relatively microscopic, making it difficult to collect data through cameras and assess the severity of defects. Therefore, this invention has more reliable detection accuracy, more convenient operation, and a simpler defect level assessment method (for example, when the amount of data from a certain angle exceeds 40% of the data from other angles, it can be determined as a severe failure, and alarm systems such as speakers should be used to notify operators and maintenance personnel, thereby reducing the losses caused by the ineffective operation of the lifting component 3).

[0053] Furthermore, this invention can also quantify the fault level and improve its visualization capabilities. For example, using the angle data of the lifting component 3 within the first month of operation as the base data, the fault level can be quantified by evaluating the deviation between the angle data of each subsequent month and the base data.

[0054] Reference Figure 13When the reinforcing bar 9 rises or falls along the first step 311 of different grades, it can push the inclined pressure member 38 to swing at different angles (i.e., R has different values). (Refer to...) Figure 14 and Figure 15 The swing angle of the inclined pressure member 38 increases as the steel bar 9 rises, i.e., R1 < R2.

[0055] Reference Figure 9 The tilt angle of the inclined pressure member 38 is adapted to the layout direction of the first step 311 (if the two are arranged in an X-shape, the function will fail).

[0056] Reference Figure 7 and Figure 13 The housing of the angle sensor 39 is fixedly connected to the support frame 21 (e.g., by bolts); the positions of the support frame 21 and the lifting assembly 3 are fixed to each other (e.g., the support frame 21 and the support frame 33 of the lifting assembly 3 are respectively anchored to the bottom surface of the processing workshop, or the support frame 21 and the support frame 33 are fixed by welding several square tubes). The detection shaft of the angle sensor 39 is coaxially arranged and fixedly connected to the connecting shaft 391 (e.g., by bolts), and the top of the inclined pressure member 38 is fixedly connected to the connecting shaft 391 in a cross shape (e.g., by bolts); the connecting shaft 391 is arranged laterally above the top of the fixed plate 31, so the reinforcing bar 9 can pass through the gap between the connecting shaft 391 and the fixed plate 31 and roll into the high-level longitudinal conveying assembly 2.

[0057] Reference Figure 7 Angle sensors 39 are installed in pairs at both ends of the connecting shaft 391 to provide stable support for the connecting shaft 391; the two angle sensors 39 are respectively located at both ends of the lifting assembly 3.

[0058] Reference Figure 4 and Figure 16 When there is no reinforcing bar 9 at the first step 311 position, the first bottom surface 381 (middle part) of the inclined pressure member 38 can be adapted to overlap the guide crossbar 36, and at this time, the bottom end of the inclined pressure member 38 and the top surface of the low longitudinal conveying component 5 form a material flow gap 8 for the movement of the reinforcing bar 9 (otherwise, the bottom end of the inclined pressure member 38 will be lower than the top surface of the low longitudinal conveying component 5, that is, the inclined pressure member 38 and the conveyor chain 12 are intersected, and the reinforcing bar 9 cannot move to below the inclined pressure member 38).

[0059] Reference Figure 2 The top of the side wall of the fixed plate 31 is provided with a rear extension plate 312. The rear extension plate 312 is inclined and points to the top opening of the inner cavity of the support frame 21, which is used to guide the steel bar 9 located at the top edge of the fixed plate 31 to the first conveyor roller 22.

[0060] Reference Figure 17 and Figure 18The steel bar processing production line includes a stepped steel bar feeding module, a cross-feeding component 4, a low-level longitudinal conveying component 5, a first bending machine 6, and a second bending machine 7. Two low-level transverse conveying components 1 are provided (low-level transverse conveying component a1a and low-level transverse conveying component b1b) and are located on either side of the cross-feeding component 4. One low-level transverse conveying component 1 (i.e., low-level transverse conveying component a1a) is located between the lifting component 3 and the cross-feeding component 4, and the other low-level transverse conveying component 1 (i.e., low-level transverse conveying component b1b) is located between the low-level longitudinal conveying component 5 and the cross-feeding component 4. The first bending machine 6 is located at the end of the high-level longitudinal conveying component 2; the second bending machine 7 is located at the end of the low-level longitudinal conveying component 5.

[0061] Reference Figure 18 The cross-feeding assembly 4 is used to transport the straightened and cut steel bars 9 (the tensioning equipment and the cutting equipment are located at the end of the cross-feeding module away from the low-position transverse conveying assembly 1). In actual operation, steel bars 9 for different purposes need to be bent into different shapes, so different bending machines (including the first bending machine 6 and the second bending machine 7) need to be configured. The cross-feeding assembly 4 is used to transport different steel bars 9 to different bending machine positions.

[0062] Reference Figure 17 When the swing angle of the inclined pressure member 38 reaches its maximum value (i.e., it is determined that the lifted steel bar 9 has moved to the top of the fixed plate 31), the cross material distribution component 4 can control the steel bar 9 used for replenishment (i.e. the next steel bar 9) to roll in the direction of the lifting component 3; thereby reducing the time interval of steel bar 9 feeding and maximizing the conveying efficiency.

[0063] Reference Figure 19The cross-feeding assembly 4 includes a first support 41, a second conveyor roller 42, and a feeding structure. The bottom of the first support 41 is fixedly connected to the workshop floor (e.g., anchored). The feeding structures are arranged in pairs, with the two pairs of feeding structures located on opposite sides of the first support 41. The second conveyor roller 42 is rotatably mounted laterally inside the first support 41. The second conveyor roller 42 is horizontally positioned, and its axis is parallel to the length direction of the first crossbar 11. Both ends of the second conveyor roller 42 are rotatably connected to the cross-feeding assembly 4 (e.g., via bearings). The second conveyor roller 42 is connected to a fourth motor. The housing of the fourth motor is fixedly installed on the outer wall of the first support 41 (e.g., via bolts). The fourth output shaft of the fourth motor is coaxially mounted and fixedly connected to the second conveyor roller 42 (e.g., the fourth output shaft passes through a through hole on the first support 41 and is inserted into a first blind hole at the end face of the second conveyor roller 42, and the fourth output shaft is fixedly connected to the second conveyor roller 42 via bolts). The fourth motor can drive the second conveyor roller 42 to rotate, thereby driving the steel bar 9 pressed onto the second conveyor roller 42 to move. The second conveyor roller 42 has a second annular groove on its circumferential surface for clamping the reinforcing bar 9.

[0064] Reference Figure 19 and Figure 20 The material distribution structure includes a swing arm 43 and a first linear actuator 44. The middle part of the swing arm 43 is rotatably connected to the first support 41 (e.g., via a rotating shaft and bearing). The top end of the output shaft of the first linear actuator 44 is rotatably connected to the bottom end of the swing arm 43 (e.g., via a rotating shaft and bearing). The bottom end of the housing of the first linear actuator 44 is rotatably connected to the first support 41 (e.g., via a rotating shaft and bearing). When the output shaft of the first linear actuator 44 extends or retracts, it can drive the swing arm 43 to rotate. The two paired swing arms 43 can cross in an X-shape, thereby lifting the reinforcing bar 9 that was originally pressed onto the second conveying roller 42 upward. Then, either side of the swing arm 43 can rotate downward, causing the reinforcing bar 9 to roll downward along the other side of the swing arm 43, thereby controlling the selective rolling of the reinforcing bar 9 towards the lower lateral conveying assembly a1a or the lower lateral conveying assembly b1b, thus achieving material distribution of the reinforcing bar 9.

[0065] Reference Figure 19 A guide plate 45 is installed between the swing arm 43 and the low-position lateral conveying assembly 1. During the rolling of the reinforcing bar 9, the guide plate 45 serves as a transition between the swing arm 43 and the low-position lateral conveying assembly 1, thereby improving the smoothness of the fixing of the reinforcing bar 9. The side wall of the guide plate 45 is fixedly connected to the side wall of the first crossbar 11 (e.g., by bolts) to make way for the conveyor chain 12.

[0066] Reference Figure 19 and Figure 20The first support 41 is provided in several parts, and a clearance gap 410 is provided between adjacent first supports 41. The clearance gap 410 is used to provide space for the swing arm 43 to accommodate and move, and to avoid interference.

[0067] Reference Figure 19 The low-position longitudinal conveying assembly 5 includes a receiving platform 51, a second support 52, a third conveying roller 53, and a fifth motor 54. The receiving platform 51 is fixedly pressed onto the processing workshop floor (e.g., anchored). The second support 52 is fixedly erected on the upper surface of the receiving platform 51 (e.g., vertically fixed by bolts). The third conveying roller 53 is laterally and rotatably disposed within the cavity of the second support 52 (e.g., rotatably connected by bearings and a shaft). The housing of the fifth motor 54 is fixedly mounted on the outer wall of the second support 52 by bolts. The fifth output shaft of the fifth motor 54 passes through the through hole of the second support 52 and is inserted into the second blind hole at the end face of the third conveying roller 53. The fifth output shaft is coaxial with the third conveying roller 53 and fixedly connected by bolts. The axis of the third conveying roller 53 is parallel to the axis of the second conveying roller 42. The fifth motor 54 can drive the third conveying roller 53 to rotate, thereby driving the steel bar 9 pressed onto the third conveying roller 53 to move. A third annular groove for securing the steel bar 9 is provided on the circumferential surface of the third conveying roller 53.

[0068] Reference Figure 18 and Figure 19 The second conveyor roller 42 is provided in several units and arranged in a linear array along the longitudinal direction; the third conveyor roller 53 is provided in several units and arranged in a linear array along the longitudinal direction.

[0069] The first linear actuator 44 is an electric actuator, a pneumatic actuator, a hydraulic actuator, or a combination thereof (e.g., an electro-hydraulic actuator).

[0070] The present invention also includes an electrical cabinet, which is fixedly installed on the floor of the processing workshop by bolts; the first motor, the second motor 23, the third motor 351, the fourth motor, the fifth motor 54, the first linear actuator 44, the angle sensor 39, the first bending machine 6, and the second bending machine 7 are respectively connected to the electrical cabinet by wires and signal lines; the electrical cabinet is connected to the peripheral power supply and peripheral controller (e.g., a computer; the storage unit and the arithmetic unit are installed in the computer) by wires and signal lines, and the peripheral controller controls the start and stop and other working states of the first motor, the second motor 23, the third motor 351, the fourth motor, the fifth motor 54, the first linear actuator 44, the angle sensor 39, the first bending machine 6, and the second bending machine 7 in the present invention through the electrical cabinet.

[0071] The first motor, the second motor 23, the third motor 351, the fourth motor, and the fifth motor 54 are all controllable motors (such as servo motors or stepper motors). By inputting electrical signals to the controllable motors through an external controller, the speed, number of revolutions per rotation, angle of rotation per rotation, and start / stop timing of the controllable motors can be controlled.

[0072] The steel bar processing technology involves processing steel bars (9) using a steel bar processing production line. The steps include... S1. Convey the reinforcing bar 9, and at the same time determine the position of the first step 311 and / or the second step 321 that has failed (lifting function) based on the number of times the reinforcing bar 9 climbs different first steps 311.

[0073] S2, bend the reinforcing bar 9.

[0074] This invention features a simple structure and reliable function, and includes an inclined pressing member 38 for obliquely pressing the reinforcing bar 9. Firstly, by increasing the oblique pressure, the tendency of the reinforcing bar 9 to move inwards towards the first V-groove 3110 is enhanced, reducing the probability of the reinforcing bar 9 detaching from the overlapping groove 31100. Secondly, even if the reinforcing bar 9 detaches from the overlapping groove 31100, it can be quickly stopped, preventing it from falling downwards in multiple stages. Thirdly, the lifting plate 32 can drive the stopped reinforcing bar 9 to attempt to climb again and again, thereby improving the overall lifting success rate.
