Description

Technical Field

[0001] This utility model relates to the field of stirrup conveying technology, specifically to a positioning mechanism for stirrup conveying. Background Technology

[0002] The main function of the reinforcing cage is similar to that of the longitudinal reinforcement in a column, primarily resisting tension. While concrete has high compressive strength, its tensile strength is very low. The cage acts as a restraint on the pile concrete, enabling it to withstand a certain amount of axial tensile force.

[0003] Existing rebar cage forming machines mainly include a bending device, and main bar conveying devices and stirrup conveying devices with mutually perpendicular conveying directions. The main bar conveying device conveys a certain amount of main bars, forming a parallel, spaced-apart ring structure. The stirrup conveying device conveys a certain amount of stirrups, which, under the bending action of the bending device, surround the main bars and are spaced apart along the length of the main bars.

[0004] In actual production, ensuring the consistency of the bending position of each stirrup is beneficial to improving the consistency of the welding position between the stirrup and the main reinforcement, thereby improving the quality of the reinforcing cage. Therefore, how to improve the consistency of the stirrup's position during each transfer, and thus ensure the consistency of the bending position of each stirrup, is an urgent technical problem to be solved. Utility Model Content

The clamping member is slidably disposed on the connecting rod and is used to clamp the stirrup. When the clamping member moves closer to the limiting plate along the connecting rod, the clamping member is in a closed state; when the clamping member moves away from the limiting plate along the connecting rod, the clamping member is in an open state.

[0008] A further technical solution is that the positioning mechanism further includes a first driving member; the first driving member is disposed on the connecting rod; the first driving member is connected to the clamping member; wherein, the first driving member is used to drive the clamping member to move closer to or away from the limiting plate along the connecting rod.

[0011] A further technical solution is as follows: the clamping arm includes a first clamping plate and a second clamping plate; the first clamping plate is disposed at the connection; the second clamping plate is disposed opposite to the first clamping plate; a stirrup channel is formed between the second clamping plate and the first clamping plate; the second clamping plate is connected to the second driving member; wherein, the second clamping plate is used to move closer to or further away from the first clamping plate under the drive of the second driving member, so as to adjust the size of the stirrup channel.

[0012] A further technical solution is that the area of ​​the longitudinal section of the stirrup clamp gradually decreases along the direction from one end of the connecting rod to the other end of the connecting rod.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1: This Example 1 provides a positioning mechanism for conveying stirrups, such as... Figure 1 As shown, the device includes a connecting rod 1, a limiting plate 2, and a clamping member 3. One end of the connecting rod 1 is connected to the outlet of the stirrup conveying device. The limiting plate 2 is disposed at the other end of the connecting rod 1 and is used to abut against the end of the stirrup. The clamping member 3 is slidably disposed on the connecting rod 1 and is used to clamp the stirrup. When the clamping member 3 moves closer to the limiting plate 2 along the connecting rod 1, the clamping member 3 is in a closed state. When the clamping member 3 moves away from the limiting plate 2 along the connecting rod 1, the clamping member 3 is in an open state.

[0025] For example, in implementation, one end of the connecting rod 1 is used to connect to the discharge port of the stirrup conveying device. The limiting plate 2 is connected to the other end of the connecting rod 1 by means of welding, screwing, or integral molding. The clamping member 3 is slidably connected to the connecting rod 1 by sleeve or other sliding structure, so that the clamping member 3 can slide along the connecting rod 1 towards or away from the limiting plate 2.

[0026] During use, firstly, one end of the connecting rod 1 is connected to the outlet of the stirrup conveying device through welding, screwing, or other methods, ensuring that the extension direction of the connecting rod 1 is consistent with the direction in which the stirrup is conveyed by the stirrup conveying device. Next, the clamping member 3 is aligned with the outlet of the stirrup conveying device to facilitate clamping the stirrup. Then, the clamping member 3 is opened, and external force drives it to move along the connecting rod 1 away from the limiting plate 2 to the clamping position. The clamping position is preset according to requirements. After one end of the stirrup is output from the outlet of the stirrup conveying device, it gradually moves into the clamping member 3. At this point, the clamping member 3 closes to hold the stirrup within it. External force drives the clamping member 3 to move along the connecting rod 1 towards the limiting plate 2 until the end of the stirrup abuts against the limiting plate 2. Alternatively, external force drives the clamping member 3 to move along the connecting rod 1 away from the stirrup conveying device outlet until the end of the stirrup abuts against the limiting plate 2. This completes one positioning and transfer cycle. Repeating this process allows for the positioning and transfer of multiple stirrups. The aim is to improve the consistency of the stirrup end position during each transfer, thereby ensuring consistent bending positions and reducing the likelihood of subsequent welding defects and irregular shapes due to bending position deviations, ultimately improving welding quality and the overall quality of the reinforcing cage.

[0027] Example 2: To achieve the purpose of driving the clamping member 3 to move closer to or away from the limiting plate 2 along the connecting rod 1, based on Example 1 above, in this example, as... Figure 1 As shown, the positioning mechanism further includes a first driving member 4; the first driving member 4 is disposed on the connecting rod 1; the first driving member 4 is connected to the clamping member 3; wherein, the first driving member 4 is used to drive the clamping member 3 to move closer to or away from the limiting plate 2 along the connecting rod 1.

[0028] For example, in the implementation process, the positioning mechanism further includes a first driving component 4, which can be a cylinder, a hydraulic telescopic rod, or a telescopic mechanism. The first driving component 4 can be connected to the discharge port of the connecting rod 1 or the stirrup conveying device by means of screw fixing, welding fixing, snap-fit, etc., and the drive shaft of the first driving component 4 is connected to the clamping component 3.

[0029] During use, operating the first driving component 4 can drive the clamping component 3 to move closer to or further away from the limiting plate 2 along the connecting rod 1. This aims to improve the automation level of the positioning mechanism, reduce manual labor intensity, thereby increasing production efficiency and reducing human error.

[0030] Example 3: Based on Example 2 above, in this example, as follows...Figure 2 As shown, the clamping member 3 includes a connecting plate 31 and a gripper 32; the connecting plate 31 is slidably disposed on the connecting rod 1 and is connected to the first driving member 4; the gripper 32 is disposed on the connecting plate 31.

[0031] For example, in implementation, the clamping member 3 includes a connecting plate 31 and a gripper 32. The connecting plate 31 is slidably connected to the connecting rod 1 via a sleeve or other sliding structure, and is connected to the drive shaft of the first driving member 4 by means of screwing, snap-fit, or other methods, allowing the connecting plate 31 to move closer to or further away from the limiting plate 2 along the connecting rod 1 under the drive of the first driving member 4. The gripper has an opening and closing function for clamping or releasing the stirrups. The gripper 32 is connected to the connecting plate 31 by welding, screwing, or other methods.

[0032] During use, the gripper 32 is first opened, and the first driving member 4 drives the connecting plate 31 along the connecting rod 1 towards the discharge port of the stirrup conveying device to the gripping position, thereby driving the gripper 32 to move synchronously. Next, the gripper 32 is closed to grip the stirrup. Then, the first driving member 4 drives the connecting plate 31 along the connecting rod 1 towards the limiting plate 2 until the end of the stirrup abuts against the limiting plate 2. This aims to achieve the purpose of slidingly connecting the gripper 32 to the connecting rod 1 via the connecting plate 31.

[0033] Example 4: Based on Example 3 above, in this example, as... Figure 2 As shown, the gripper 32 includes a second driving member 321 and a gripping arm 322; the second driving member 321 is disposed on the connecting plate 31; the gripping arm 322 is connected to the second driving member 321.

[0034] For example, in implementation, the gripper 32 includes a second driving member 321 and a gripping arm 322. The second driving member 321 can be a cylinder, a hydraulic telescopic rod, or a telescopic mechanism. The second driving member 321 is connected to the connecting plate 31 by welding, screwing, or snap-fitting. The gripping arm 322 is connected to the output shaft of the second driving member 321 by welding, screwing, or other methods.

[0035] During use, operating the second drive component 321 can close or open the clamping arm 322, in order to achieve the purpose of clamping or releasing the stirrups.

[0036] Example 5: Based on Example 4 above, in this example, as... Figure 2As shown, the clamping arm 322 includes a first clamping plate 3221 and a second clamping plate 3222; the first clamping plate 3221 is disposed at the connection; the second clamping plate 3222 is disposed opposite to the first clamping plate 3221; a stirrup channel 5 is formed between the second clamping plate 3222 and the first clamping plate 3221; the second clamping plate 3222 is connected to the second driving member 321; wherein, the second clamping plate 3222 is used to move closer to or further away from the first clamping plate 3221 under the drive of the second driving member 321, so as to adjust the size of the stirrup channel 5.

[0037] For example, in implementation, the clamping arm 322 includes a first clamping plate 3221 and a second clamping plate 3222. The first clamping plate 3221 is connected to the edge of one end of the connecting plate 31 by welding, screwing, or integral molding. The second clamping plate 3222 is disposed opposite to the first clamping plate 3221, and is located on the side of the first clamping plate 3221 away from the other end of the connecting plate 31, forming a stirrup clamping channel 5 between the second clamping plate 3222 and the first clamping plate 3221, corresponding to the discharge port on the stirrup clinker device. This stirrup clamping channel 5 is used to clamp the stirrups. The second clamping plate 3222 is connected to the drive shaft of the second driving member 321 by welding, screwing, or integral molding.

[0038] During use, the second driving component 321 can drive the second clamping plate 3222 to move closer to or further away from the first clamping plate 3221 to adjust the size of the stirrup clamping channel 5. On one hand, this aims to achieve the purpose of clamping and releasing stirrups using the second clamping plate 3222 and the first clamping plate 3221. On the other hand, it aims to achieve the purpose of clamping stirrups of different diameters using the second clamping plate 3222 and the first clamping plate 3221.

[0039] In one alternative implementation, anti-slip textures or pads can be provided within the stirrup clamping channel 5. This can enhance the friction between the first clamping plate 3221 and the stirrup, as well as between the second clamping plate 3222 and the stirrup. The aim is to ensure the stability of the stirrup clamping when moving along the connecting rod 1 towards the limiting plate 2.

[0040] Example 6: Based on Example 5 above, in this example, as... Figure 2 As shown, the area of ​​the longitudinal section of the stirrup clamp 5 gradually decreases along the direction from one end of the connecting rod 1 to the other end of the connecting rod 1.

[0041] For example, during implementation, the area of ​​the longitudinal section of the stirrup clamp 5 gradually decreases along the direction from one end of the connecting rod 1 to the other end, making the stirrup clamp 5 a conical structure with a larger inlet end. The inlet end of the stirrup clamp 5 corresponds to the discharge port on the stirrup clinker device. The aim is to guide the stirrups using the conical structure of the stirrup clamp 5, thereby making it easier for the stirrups to enter the stirrup clamp 5.

[0042] Example 7: Based on Example 2 above, in this example, the positioning mechanism further includes a detection mechanism; the detection mechanism includes a detection unit and a control unit; the detection unit is disposed on the connecting rod 1, and the detection unit is used to detect whether the limiting plate 2 abuts against the stirrup; the input end of the control unit is connected to the detection unit, and the output end of the control unit is connected to the first driving member 4.

[0043] For example, in implementation, the positioning mechanism also includes a detection mechanism, which comprises a detection unit and a control unit, not shown in the figure. The detection unit can be a contact sensor (model GT-H10, D5SN, etc.) or a non-contact sensor (model LD1-H030, LD1-H100, etc.). The location of the detection unit is not particularly limited, as long as it can accurately detect whether the end of the hoop held by the clamping member 3 abuts against the limiting plate 2. For example, the detection unit is connected to the connecting rod 1, the limiting plate 2, etc., by means of screws, snap-fit ​​connections, etc. This detection unit is used to detect whether the end of the hoop held by the clamping member 3 abuts against the limiting plate 2. The control unit can be a Siemens S7-1200 series, a Mitsubishi FX5U series, etc. The input terminal of the control unit is connected to the output terminal of the detection unit via a wire, and the output terminal of the control unit is connected to the first driving member 4.

[0044] During use, after the clamping member 3 clamps the stirrup, the first driving member 4 drives the clamping member to move along the connecting rod 1 towards the limiting plate 2 to the release position. This release position is the position of the clamping member 3 when the end of the stirrup abuts against the limiting plate 2. At this time, the detection unit detects whether the end of the stirrup abuts against the limiting plate 2.

[0045] When the detection unit detects that the end of the stirrup is abutting against the limiting plate 2, the detection unit generates a first signal. The control unit acquires the first signal and generates a first command. After responding to the first command, the first driving member 4 is driven to move along the connecting rod 1 away from the limiting plate 2 to perform the next round of stirrup clamping.

[0046] When the detection unit detects that the end of the stirrup is not abutting against the limiting plate 2, the detection unit generates a second signal. The control unit acquires the second signal and generates a second command. After responding to the second command, the first driving member 4 is driven to move along the connecting rod 1 away from the limiting plate 2 to clamp the stirrup again until the end of the stirrup abuts against the limiting plate 2. This aims to reduce positioning deviations caused by under-push and improve welding quality and the overall quality of the rebar cage.

[0047] Example 8: Based on Example 1 above, in this example, as follows... Figure 1 As shown, the positioning mechanism further includes a fixing plate 6; the fixing plate 6 is disposed at one end of the connecting rod 1, and a connecting hole is provided on the fixing plate 6; the connecting hole is used to reserve a position for fixing the fixing plate 6 to the discharge port of the stirrup conveying device.

[0048] For example, in implementation, the positioning mechanism further includes a fixing plate 6. The fixing plate 6 is connected to one end of the connecting rod 1 by means of welding, screwing, or integral molding. A connecting hole is provided on the fixing plate 6.

[0049] During use, the fixing plate 6 is fixed to the outlet of the stirrup input device using the connecting holes on the fixing plate 6, so as to connect the connecting rod 1 to the outlet of the stirrup input device.
