Description

Technical Field

[0001] This application relates to the technical field of production of pipe pile products, and particularly to a bar conveying device and an automatic steel bar threading device. Background Art

[0002] Reinforced concrete piles are widely used in the foundation construction of various buildings. The steel bar part is usually prefabricated into a cage shape, called cage bars, which mainly includes main bars distributed longitudinally and hoop bars distributed in a circumferential spiral shape. In the current industry's production process of cage bars, it mainly includes processes such as cutting the main bars to a fixed length, upsetting, and steel bar threading and roll welding; among them, the steel bar threading process still mainly relies on manual labor. This process requires selecting main bars with qualified upsetting and uniform length (excluding unqualified main bars), threading them into a roll welding machine for roll welding to ensure the quality of the cage bars.

[0003] In recent years, automatic steel bar threading devices have also emerged in the industry, but they only replace manual steel bar threading and have not yet achieved the function of excluding unqualified main bars. Existing automatic steel bar threading devices can only simply default that the main bars entering the device are all qualified products. Therefore, if the main bars produced by upstream equipment are unqualified, existing automatic steel bar threading devices can only continue to thread and roll weld the unqualified main bars as qualified products. Moreover, during this process, it is difficult for manual workers to detect unqualified main bars and take intervention measures, which will ultimately lead to uncontrolled quality of the cage bars and thus affect the qualification rate of the cage bars. Summary of the Utility Model

[0004] Based on this, the purpose of this application is to provide a bar conveying device and an automatic steel bar threading device including the bar conveying device, so as to solve the problem that in the prior art, when conveying bars (such as main bars used for producing cage bars), the function of excluding unqualified bars cannot be achieved.

[0006] A conveying mechanism having a receiving end and a discharging end oppositely arranged in a first direction, and the conveying mechanism is used to convey bars from the receiving end to the discharging end;

[0007] A receiving mechanism, including a first driving source and a receiving frame, the receiving frame is connected to the first driving source and is rotatably arranged at the receiving end, and the receiving frame is provided with a receiving groove having an opening;

[0008] A control module, the control module includes a detection element and a control element that communicate with each other, the control element is also communicatively connected to the first driving source, the detection element is used to detect whether the bar stock is qualified, and the control element is used to control the first driving source to drive the material receiving rack to rotate forward around a first axis extending in a second direction perpendicular to the first direction when the bar stock is qualified, so that the opening of the material receiving groove faces away from the conveying mechanism, or control the first driving source to drive the material receiving rack to rotate reversely around the first axis when the bar stock is unqualified, so that the opening of the material receiving groove faces the conveying mechanism.

[0009] In one embodiment, the conveying mechanism includes a second driving source, a support frame, and a conveying component movably arranged on the support frame. At least one receiving groove for accommodating the bar stock is formed on the conveying component, and the conveying component can move relative to the support frame under the drive of the second driving source, so that the receiving groove can move back and forth between the material receiving end and the material discharging end.

[0010] In one embodiment, the material receiving mechanism further includes a first rotating shaft coaxially arranged with the first axis. The first rotating shaft is rotatably arranged on the support frame around its own central axis.

[0011] In one embodiment, there are a plurality of the material receiving racks, all the material receiving racks are arranged at intervals in the second direction, and all the material receiving racks are sleeved on the first rotating shaft.

[0012] In one embodiment, the conveying component includes a first driving wheel, a second driving wheel, and a conveying chain. The first driving wheel and the second driving wheel are arranged at intervals and can rotate around their own central axes respectively. The conveying chain is wound around the first driving wheel and the second driving wheel. The receiving groove is formed on the conveying chain, and the conveying chain can perform a cyclic rotary motion when the first driving wheel and the second driving wheel rotate.

[0013] In one embodiment, the conveying component further includes a second rotating shaft drivingly connected to the second driving source. The second rotating shaft is coaxially arranged with a second axis parallel to the first axis and is rotatably arranged on the support frame around its own central axis, and the second rotating shaft is also coaxially connected to the first driving wheel or the second driving wheel.

[0014] In one embodiment, there are a plurality of the conveying components, and all the conveying components are distributed at intervals in the second direction.

[0015] In one embodiment, the support frame has an inclined lapping surface at a position close to the discharging end, and in the direction from the feeding end to the discharging end, the height of the lapping surface gradually decreases.

[0016] In one embodiment, the bar feeding device further includes a discharging mechanism arranged at the discharging end.

[0019] In this way, the bar feeding device is realized to have both the function of transferring qualified bars and the function of rejecting unqualified bars at the same time, and the above two functions are combined into one, which not only simplifies the structure and operation, reduces the production cost of the device, improves the reliability of the device, but also can ensure that the bars entering the conveying mechanism are all qualified products. When the bar feeding device is applied to the automatic bar threading device, it can ensure that the main bars entering the conveying mechanism are all qualified products, and thus can effectively ensure the quality of the subsequent produced cage bars.

[0035] This application provides a bar conveying device and an automatic steel bar threading device. The automatic steel bar threading device includes a bar conveying device and a steel bar threading device located downstream of the bar conveying device. The bar conveying device is used to convey bars, and the steel bar threading device is used to sequentially thread the conveyed bars (such as steel bars) through end plates to prepare for the final production of reinforced concrete pipe piles for construction.

[0036] Taking the bar conveying device applied to the automatic steel bar threading device as an example, the structure of the bar conveying device in this application will be described below. It can be understood that in other embodiments, the bar conveying device of this application is not limited to being only applicable to the automatic steel bar threading device, that is, it is not limited to only being used to convey steel bars, and can also be used to convey any bar, which is not limited here.

[0037] Figures 1 to 3 Figure 10 shows a bar conveying device 10 provided by an embodiment of this application. The bar conveying device 10 provided by the embodiment of this application includes a conveying mechanism 100, a material receiving mechanism 200, and a control module (not shown in the figure). The conveying mechanism 100 has a material receiving end 101 and a discharging end 102 oppositely arranged along a first direction (the X direction shown in the figure), and is used to convey the bar 40 from the material receiving end 101 to the discharging end 102; the material receiving mechanism 200 is arranged at the material receiving end 101, includes a first driving source 210 and a material receiving frame 220. The material receiving frame 220 is connected to the first driving source 210 and is rotatably arranged at the material receiving end 101, and the material receiving frame 220 is provided with a material receiving groove 220a for accommodating the bar 40, and is used to transfer the bar 40 conveyed from the upstream device to the conveying mechanism 100; the control module includes a detection element and a control element that communicate with each other. The control element is communicatively connected to the first driving source 210. The detection element is used to detect whether the bar 40 conveyed from the upstream is qualified, and the control element is used to control the first driving source 210 to drive the material receiving frame 220 to act to complete the transfer of the qualified bar 40 to the conveying mechanism 100 and discharge the unqualified bar 40 out of the device.

[0038] Specifically, in one embodiment, in combination with Figures 1 to 4As shown in the figure, the conveying mechanism 100 includes a second driving source 110, a support frame 120, and a conveying component 130 movably arranged on the support frame 120. At least one receiving groove 133a for receiving the bar stock 40 is formed on the conveying component 130, and the conveying component 130 can move relative to the support frame 120 under the drive of the second driving source 110, so that the receiving groove 133a can move back and forth between the material receiving end 101 and the material discharging end 102, thereby being able to cyclically complete the conveying of the bar stock 40.

[0039] As Figure 5 shown in the figure, the material receiving mechanism 200 further includes a first rotating shaft 230 coaxially arranged with a first axis 50 extending in a second direction (the Y direction shown in the figure) perpendicular to the first direction. The first rotating shaft 230 is rotatably arranged on the support frame 120 around its own central axis, and a first connecting head 240 is fixedly sleeved on the first rotating shaft 230. The first driving source 210 can be a cylinder or an electric cylinder, and its output end is connected to the first connecting head 240, so that when the output end of the first driving source 210 extends or retracts, it can drive the first connecting head 240 and the first rotating shaft 230 to rotate around the first axis 50 together. The material receiving frame 220 is fixedly sleeved on the first rotating shaft 230, so that the first driving source 210 is connected to the material receiving frame 220 through the first rotating shaft 230. Optionally, the material receiving frame 220 is L-shaped, so that the material receiving groove 220a is V-shaped. When the first driving source 210 drives the first rotating shaft 230 to rotate, the first rotating shaft 230 can also drive the material receiving frame 220 to rotate, so that the material receiving groove 220a of the material receiving frame 220 can face away from or face the conveying mechanism 100.

[0040] It can be understood that the shape of the material receiving groove 220a is not limited to V-shaped, and can also be arc-shaped or any shape. The shape of the material receiving frame 220 is not limited to L-shaped, and the material receiving frame 220 can also be directly connected to the first driving source 210, and the first driving source 210 directly drives the material receiving frame 220 to act. It is not limited to being connected to the material receiving frame 220 only through the first rotating shaft 230, and the above are not limited.

[0041] As Figure 6 shown in the figure, when observing from the direction from outside the paper surface to inside the paper surface, when the output end of the first driving source 210 extends, the first connecting head 240 can drive the first rotating shaft 230 and the material receiving frame 220 to rotate around the first axis 50 in the clockwise direction by an angle, so that the opening of the material receiving groove 220a faces away from the conveying mechanism 100; as Figure 7 shown in the figure, when the output end of the first driving source 210 retracts, the first connecting head 240 can drive the first rotating shaft 230 and the material receiving frame 220 to rotate around the first axis 50 in the counterclockwise direction by an angle, so that the opening of the material receiving groove 220a faces the conveying mechanism 100.

[0042] Thus, since the control element is communicatively connected to the first driving source 210, when the bar stock 40 transmitted from the upstream is determined to be qualified, the control element can control the first driving source 210 to drive the receiving rack 220 to rotate by an angle, so that the receiving slot 220a of the receiving rack 220 faces away from the conveying mechanism 100, enabling the qualified bar stock 40 conveyed from the upstream to fall into the receiving slot 220a; conversely, when the bar stock 40 transmitted from the upstream is determined to be unqualified, the control module can control the first driving source 210 to drive the receiving rack 220 to reverse by an angle, so that the receiving slot 220a of the receiving rack 220 faces the conveying mechanism 100, preventing the unqualified bar stock 40 conveyed from the upstream from falling into the receiving slot 220a, and allowing it to slide along the outside of the receiving rack 220 to the outside of the device, while the qualified bar stock 40 can be transferred onto the conveying mechanism 100. In this way, the bar stock conveying device 10 simultaneously has the function of transferring the qualified bar stock 40 and the function of removing the unqualified bar stock 40, combines the above two functions into one, simplifies the structure and operation, reduces the production cost of the device, improves the reliability of the device, and can ensure that the bar stock 40 entering the conveying mechanism 100 is all qualified. When the bar stock conveying device 10 is applied to an automatic bar threading device, it can ensure that the main bars entering the conveying mechanism 100 are all qualified, and thus can effectively guarantee the quality of the subsequent produced cage bars.

[0043] Please continue to refer to Figure 3 and Figure 4 In terms of the structure of the conveying assembly 130, the conveying assembly 130 includes a first driving wheel 131, a second driving wheel 132, and a conveyor chain 133. The first driving wheel 131 and the second driving wheel 132 are spaced apart along the first direction and can rotate respectively around their own central axes. The conveyor chain 133 is wound around the first driving wheel 131 and the second driving wheel 132, and a receiving groove 133a is formed in the conveyor chain 133. In the illustrated embodiment, a plurality of receiving grooves 133a are formed in the conveyor chain 133, so that multiple bar stocks 40 can be conveyed simultaneously. When the first driving wheel 131 and the second driving wheel 132 rotate, the conveyor chain 133 can perform a cyclic rotational movement to cyclically complete the conveying of the bar stock 40.

[0044] Similar to the first driving source 210 being connected to the receiving frame 220 through the first rotating shaft 230, the conveying mechanism 100 further includes a second rotating shaft 140. The second driving source 110 may be a motor, which is connected to the first transmission wheel 131 or the second transmission wheel 132 through the second rotating shaft 140. Specifically, the second rotating shaft 140 is coaxially arranged with a second axis 60 parallel to the first axis 50, and is rotatably arranged on the support frame 120 around its own central axis. The second driving source 110 is connected to the second rotating shaft 140 through a sprocket chain, and the second rotating shaft 140 is also coaxially connected to the first transmission wheel 131 or the second transmission wheel 132. When the second driving source 110 is started, the second driving source 110 can drive the second rotating shaft 140 to rotate around its own central axis, and drive the first transmission wheel 131 or the second transmission wheel 132 to rotate synchronously, so that the conveying chain 133 can perform a cyclic rotation motion.

[0045] It is worth noting that when the bar 40 is a main bar for manufacturing a pipe pile, since the main bar is tens of meters long, in order to support the main bar in the length direction of the main bar and prevent the main bar from falling during the process of being transferred from the receiving mechanism 200 to the conveying mechanism 100, in a preferred embodiment, Figure 2 As shown, there are multiple receiving racks 220, all of which are arranged at intervals along the second direction, and all of which are sleeved on the first rotating shaft 230. In this way, when the first rotating shaft 230 rotates around its own central axis (i.e., the first axis 50), all of the receiving racks 220 rotate around the first axis 50 synchronously at the same time. In this way, since multiple receiving racks 220 simultaneously support the bar material 40 for transfer, the bar material 40 with a long length can be transferred stably, preventing the bar material 40 from falling and causing an accident.

[0046] Just because the bar 40 is long in some cases, for the same reason, in an optional embodiment, as Figure 1 As shown, the support frame 120 includes a plurality of support plates 121 arranged at intervals along the second direction, and the conveying components 130 also have a plurality of corresponding ones. All the conveying components 130 are also arranged at intervals along the second direction. Each conveying component 130 is correspondingly arranged on a corresponding support plate 121. The second rotating shaft 140 connects all the conveying components 130 in series, so that when the second driving source 110 drives a conveying component 130 to move, all the conveying components 130 move synchronously, so that stable conveying and transfer can be performed when the rod material 40 is conveyed from the receiving end 101 to the discharging end 102.

[0047] Further, when the conveying mechanism 100 conveys the bar stock 40 to the discharging end 102, in order to enable the bar stock 40 to slide down from the discharging end 102 under the action of gravity, the supporting frame 120 has an inclined lapping surface 122 at a position close to the discharging end 102, and in the direction from the feeding end 101 to the discharging end 102, the height of the lapping surface 122 gradually decreases. Thus, when the bar stock 40 is conveyed to the discharging end 102, due to the gradually decreasing height of the lapping surface 122, the bar stock 40 can roll on the lapping surface 122 under the action of gravity, and thus can slide down from the discharging end 102.

[0048] In the embodiment shown in the figure, since the supporting frame 120 includes a plurality of support plates 121 arranged at intervals in the second direction, the lapping surface 122 also has a plurality of them, and each support plate 121 correspondingly has a lapping surface 122. Of course, in other embodiments, the structure of the supporting frame 120 is not limited to the embodiment shown in the figure, so the lapping surface 122 can also be a continuous surface, and there is no special limitation here.

[0049] It should also be noted that when the bar stock conveying device 10 is applied to an automatic bar stock threading device, the bar stock threading device located downstream of the bar stock conveying device 10 threads the bar stock 40 into the end plate one by one in sequence. Therefore, when a plurality of bar stocks 40 are conveyed to the discharging end 102 by the conveying mechanism 100, it is necessary to block the plurality of bar stocks 40 to prevent all the bar stocks 40 from sliding down from the discharging end 102 together.

[0050] To achieve the above purpose, preferably, referring to Figure 4 , the bar stock conveying device 10 further includes a discharging mechanism 300 arranged at the discharging end 102. The discharging mechanism 300 includes a third driving source 310, a third rotating shaft 320 and a blocking member 330. Among them, the third rotating shaft 320 is coaxially arranged with another third axis 70 parallel to the first axis 50, and the third rotating shaft 320 is rotatably arranged on the supporting frame 120 around its own central axis. The blocking member 330 is sleeved on the third rotating shaft 320 and is connected to the third driving source 310 through the third rotating shaft 320. The third driving source 310 is used to drive the third rotating shaft 320 to drive the blocking member 330 to rotate by an angle together, so that the blocking member 330 can prevent the bar stock 40 from rolling on the lapping surface 122.

[0051] Similar to the foregoing feeding rack 220 being connected to the first driving member through the first rotating shaft 230, the third driving member may also be a cylinder, and its output end is connected with a second connecting head 340. The second connecting head 340 is fixedly sleeved on the third rotating shaft 320. When the output end of the third driving source 310 extends or retracts, it can drive the second connecting head 340, the third rotating shaft 320 and the blocking member 330 to rotate around the third axis 70 together. When the blocking member 330 rotates around the third axis 70, the end of the blocking member 330 can be higher than or lower than the lapping surface 122.

[0052] Similarly, when the length of the bar stock 40 is relatively long, in order to better block the bar stock 40 and prevent the bar stock 40 from slipping, preferably, there are also a plurality of blocking members 330. All the blocking members 330 are arranged at intervals along the second direction and are simultaneously fixedly sleeved on the third rotating shaft 320. The third rotating shaft 320 connects all the blocking members 330 in series. When the third driving member drives the third rotating shaft 320 to rotate around its own central axis (i.e., the third axis 70), all the blocking members 330 can also rotate synchronously to jointly block or release the bar stock 40.

[0053] Thus, as shown in combination with Figure 3 and Figure 4 When it is necessary to block the bar stock 40, the output end of the third driving member extends. When observing from the direction from outside the paper surface to inside the paper surface in Figure 3 , the blocking member 330 rotates clockwise around the third axis 70 by an angle. When the end of the blocking member 330 is higher than the lapping surface 122, the bar stock 40 located on the lapping surface 122 can be blocked by the blocking member 330 and cannot continue to roll along the lapping surface 122; when the bar stock threading device finishes threading one bar stock 40 and needs to thread the next bar stock 40, the output end of the third driving member retracts, and the blocking member 330 rotates counterclockwise around the third axis 70 by an angle, so that the end of the blocking member 330 is lower than the lapping surface 122, and the bar stock 40 located on the lapping surface 122 can be released and grabbed by the bar stock threading device. In this way, the bar stock 40 can be successively released by the blocking member 330 and grabbed by the bar stock threading device and threaded into the end plate.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0055] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
