Description

Technical Field

[0001] This utility model relates to a rod removal device and rod processing equipment, belonging to the technical field of metal processing equipment. Background Technology

[0002] Anchor bolts are core components of prestressed wind turbine foundations. Anchor bolt processing involves multiple steps, such as chamfering, marking, thread rolling, and heat-shrink corrosion protection. Utility model patent CN213827524U discloses an anchor bolt processing system. This system includes four parallel support frames, with a conveying mechanism between adjacent support frames. At the ends of the three conveying mechanisms are sequentially located a chamfering machine, a laser marking machine, and a thread rolling machine. A storage rack is fixed to the top surface of each support frame. A feeding mechanism is provided between the three conveying mechanisms and the support frame on the same side, while an unloading mechanism is provided on the corresponding support frame on the other side.

[0003] In the aforementioned anchor bolt processing system, the chamfering machine, laser marking machine, and thread rolling machine are arranged in a horizontal row. In practical applications, depending on the specific workshop conditions, some chamfering and marking machines are arranged close together horizontally, while the thread rolling machine is located on the side of the laser marking machine furthest from its conveyor mechanism, i.e., on the longitudinal side of the laser marking machine, forming an L-shaped arrangement. Alternatively, some anchor bolt processing systems may also include a heat-shrinkable corrosion-resistant machine. However, due to limitations in workshop area and site layout, multiple machines often cannot be arranged in a horizontal row. In addition to an L-shaped arrangement, they may even be arranged in a longitudinal row. In this case, a conveyor mechanism is needed to transfer the anchor bolts between the previous and next processes.

[0004] Typically, anchor bolts require length testing during processing. This is usually done using a length measuring device on the chamfering or marking machine. While the anchor bolts are being chamfered or marked, their length is simultaneously checked. Anchor bolts that meet the length requirements are then transferred to a conveyor mechanism via a transfer device after chamfering or marking, and then moved to the next process. Anchor bolts that do not meet the length requirements need to be removed from the chamfering or marking machine, otherwise they will affect subsequent processing. Currently, the removal method involves manual handling, which not only affects production efficiency but also results in high labor intensity.

[0005] Of course, in the mechanical field, not only anchor bolts have this problem. When processing rods such as steel pipes and solid round steel bars, if length measurement or other physical quantity measurement, such as diameter, straightness, and cylindricity, is involved, and qualified products are transferred to the conveying mechanism via a transfer device and then transferred to the next process, and unqualified products need to be removed from the current process, the same technical problem exists. Utility Model Content

[0006] The purpose of this utility model is to provide a rod removal device to solve the problem that manual handling is required when removing unqualified rods in the prior art, which affects production efficiency and increases labor intensity; the purpose of this utility model is also to provide a rod processing equipment to solve the above problems.

[0007] To achieve the above objectives, the rod removal device of this utility model adopts the following technical solution:

[0008] A rod rejection device includes at least two rejection units arranged at intervals along the length of the rod. Each rejection unit includes a receiving member and a lifting mechanism for controlling the up-and-down movement of the receiving member. The top surface of the receiving member is used to support the rod and is inclined. The receiving member has a receiving position for receiving rods that have been measured and transferred by a transfer device, and a descending position for moving downwards after receiving to place qualified rods onto a conveying mechanism. Each rejection unit also includes a movable stop member used in conjunction with the receiving member and a control mechanism for controlling the movement of the movable stop member. The movable stop member has a stopping position that is higher than the top surface of the receiving member to stop the rod, and a clearance position that moves to allow unqualified rods to roll down along the top surface of the receiving member.

[0009] The beneficial effects of the above technical solution are as follows: This utility model innovatively proposes a rod rejection device, which includes at least two rejection units. Each rejection unit includes a receiving component, a lifting mechanism, a movable stop component, and a control mechanism. The top surface of the receiving component is used to support the rod, and the top surface is inclined. The lifting mechanism can control the up and down movement of the receiving component, so that the receiving component has a receiving position and a descending position. The control mechanism can control the movement of the movable stop component, so that the movable stop component has a stopping position and a clearance position. In use, the receiving component is initially in the receiving position, which can receive the measured rod. At the same time, the movable stop component is in the stopping position above the top surface of the receiving component, which can prevent the rod from rolling off. If the rod is qualified at this time, the lifting mechanism controls the receiving component to move down to the descending position, so that the qualified rod can be placed on the conveying mechanism, which facilitates the conveying of the rod to the next process. If the rod is defective, the control mechanism moves the movable stop to the clearance position, at which point the defective rod can roll off the top surface of the receiving part, thus removing the defective rod. This invention can automatically remove defective rods with high efficiency, eliminating the need for manual handling and solving the problems of reduced production efficiency and high labor intensity caused by manual handling.

[0010] Furthermore, the receiving component also has a lifting position that moves upward after receiving material to lift the defective rod upward. The movable stop is guided and installed on the receiving component in the vertical direction. An elastic element is provided between the movable stop and the receiving component to deform under force when the movable stop moves downward, so as to provide power for the movable stop to reset upward. The control mechanism includes a pulling element for connecting the movable stop and the frame or connecting the movable stop and the fixed housing of the lifting mechanism. The pulling element has a non-straightened state when the movable stop is in the stop position, either relaxed or folded, and a straightened state when the receiving component moves upward to the lifting position, so as to pull the movable stop relative to the receiving component to move downward to the clearance position.

[0011] Furthermore, the receiving component is provided with a guide groove, which includes a groove side wall and a groove bottom wall. The movable stop extends into the guide groove and is guided and cooperates with the groove side wall. The elastic element is provided between the groove bottom wall and the bottom surface of the movable stop. The groove bottom wall has a through hole that runs vertically through the groove for the pulling component to pass through.

[0012] Furthermore, the pulling element is a pull rope, which passes through the perforation.

[0013] Furthermore, the pulling member includes a fixed rod that is fixed to the movable stop and extends vertically downward. The pulling member also includes at least two connecting rods that are hinged together in sequence. One of the connecting rods at both ends is hinged to the end of the fixed rod, and the other connecting rod is hinged to the fixed housing of the frame or lifting mechanism. The fixed rod passes through the through hole. When the movable stop is in the stop position, the hinged part of the fixed rod and the connecting rod is located below the through hole.

[0014] Furthermore, the pulling component is a pull rope.

[0015] Furthermore, the pulling member includes at least two connecting rods that are hinged together in sequence, one of which is connected to a movable stop at both ends, and the other connecting rod is used to connect to the fixed housing of the frame or lifting mechanism.

[0016] Furthermore, the lifting mechanism includes a cylinder and a telescopic rod that can move up and down relative to the cylinder. The upper end of the telescopic rod is connected to the receiving part, and a downwardly extending guide rod is fixedly connected to the receiving part. Each rejection unit also includes a guide plate for fixed connection with the frame, and the guide rod passes through the guide plate and cooperates with the guide plate for vertical guidance.

[0017] Furthermore, in the projection plane perpendicular to the axis of the rod, the guide rod and the movable stop are located on both sides of the connection between the telescopic rod and the receiving part.

[0018] To achieve the above objectives, the rod processing equipment of this utility model adopts the following technical solution:

In use, the receiving component is initially in the receiving position to receive the measured rod. Simultaneously, the movable stop component is in the stopping position, above the top surface of the receiving component, preventing the rod from rolling off. If the rod is qualified, the lifting mechanism controls the receiving component to move downwards to the lowering position, allowing the qualified rod to be placed on the conveying mechanism for easy transport to the next process. If the rod is defective, the control mechanism moves the movable stop to the clearance position, at which point the defective rod can roll off the top surface of the receiving part, thus removing the defective rod. This invention can automatically remove defective rods with high efficiency, eliminating the need for manual handling and solving the problems of reduced production efficiency and high labor intensity caused by manual handling.

[0021] Furthermore, the receiving component also has a lifting position that moves upward after receiving material to lift the defective rod upward.

The pulling element has a non-straightened state when the movable stop is in the stop position, either relaxed or folded, and a straightened state when the receiving component moves upward to the lifting position, so as to pull the movable stop relative to the receiving component to move downward to the clearance position.

[0023] Furthermore, the pulling element is a pull rope, which passes through the perforation.

[0024] Furthermore, the pulling member includes a fixed rod that is fixed to the movable stop and extends vertically downward.

[0039] To address the technical problems existing in the prior art, the basic concept of this utility model is to receive measured rods using a vertically movable receiving component. The top surface of the receiving component is designed to be inclined, and a movable stop component is used to stop the rods. If the rod is qualified, the receiving rod descends, placing it on the conveying mechanism for transport to the next process. If the rod is unqualified, the movable stop component moves to a clearance position, allowing the rod to roll down along the top surface of the receiving component, thus removing the unqualified rod.

[0040] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0041] Example 1 of the rod processing equipment of this utility model:

[0042] like Figure 1As shown, the rod processing equipment in this embodiment is used to process anchor rods. It includes a frame 15 and multiple conveying mechanisms mounted on the frame 15. These multiple conveying mechanisms are a chamfering conveying mechanism 61, a marking conveying mechanism 62, and a transfer conveying mechanism 63. Each conveying mechanism includes a support wheel and a drive assembly. Multiple support wheels are arranged at intervals along the length direction of the anchor rod. If the length direction of the anchor rod is defined as the front-to-back direction, then the multiple support wheels are arranged at intervals along the front-to-back direction. Each support wheel has a groove, and each support wheel is rotatably mounted on the frame 15. The drive assembly is used to drive each support wheel to rotate synchronously, conveying the anchor rod supported on the support wheels from back to front or from front to back. The specific form of the drive assembly is prior art and will not be described further in this invention.

[0043] A chamfering machine 2 is installed at one end of the chamfering conveyor mechanism 61, and a marking machine 4 is installed at one end of the marking conveyor mechanism 62, while a distance measuring device 5 is installed at the other end. The chamfering machine 2 and the marking machine 4 are arranged side by side. A feeding device 1 is installed on one side of the chamfering conveyor mechanism 61. The feeding device 1 is used to temporarily store the anchor rods and transfer them one by one to the chamfering conveyor mechanism 61. The specific structure of the feeding device 1 is the same as that of the storage rack and feeding mechanism in the utility model patent CN213827524U, and will not be described in detail here. The chamfering conveyor mechanism 61 is responsible for conveying the anchor rods to the chamfering machine 2 for chamfering, and then conveying the chamfered anchor rods in the reverse direction to achieve unloading.

[0044] A first transfer device 31 is provided between the chamfering conveyor 61 and the marking conveyor 62. The first transfer device 31 is used to transfer the chamfered anchor rods to the marking conveyor 62. The first transfer device 31 includes a tilting frame, a storage rack, and a feeding mechanism. The specific structure is the same as the unloading mechanism, storage rack, and feeding mechanism in the utility model patent CN213827524U, and will not be described in detail here. The marking conveyor 62 is responsible for conveying the anchor rods to the marking machine 4 for marking, and then conveying the marked anchor rods in the reverse direction to unload them. While the marking machine 4 is marking the anchor rods, the distance measuring device 5 detects the length of the anchor rods.

[0045] A second transfer device 32 is provided between the marking conveyor mechanism 62 and the transfer conveyor mechanism 63. The second transfer device 32 is used to transfer the marked and length-measured anchor rods (including anchor rods with qualified length and anchor rods with unqualified length) to the transfer conveyor mechanism 63. The transfer conveyor mechanism 63 is used to transfer the anchor rods to the next process, such as flaw detection or thread rolling. The second transfer device 32 includes a tilting frame, the specific structure of which is the same as the unloading mechanism in utility model patent CN213827524U, and will not be described in detail here.

[0046] The rod processing equipment also includes a rod rejection device mounted on the frame. The rod rejection device includes at least two rejection units arranged at intervals along the length of the anchor rod, that is, each rejection unit is arranged at intervals along the front-back direction. Each rejection unit and each support wheel of the transfer conveying mechanism 63 are arranged alternately in the front-back direction, which can save space and make the layout compact.

[0047] Specifically, each rejection unit includes a receiving component and a lifting mechanism for controlling the up-and-down movement of the receiving component, such as... Figure 2 , Figure 3 , Figure 4 As shown, the lifting mechanism is a lifting cylinder 9, and the receiving component is a receiving plate 7. The lifting cylinder 9 includes a cylinder body 91 and a telescopic rod 92 that can move up and down relative to the cylinder body 91. The upper end of the telescopic rod 92 is connected to the receiving plate 7. A downwardly extending guide rod 16 is fixedly connected to the receiving plate 7. Each rejection unit also includes a guide plate 17 fixedly connected to the support profile 151 of the frame 15. The guide rod 16 passes through the guide plate 17 and cooperates with the guide plate 17 for vertical guidance. At the same time, the telescopic rod 92 also passes through the guide plate 17. Under the control of the lifting cylinder 9, the receiving plate 7 has a receiving position for receiving anchor rods that have been measured and conveyed by the second transfer device 32, a descending position for moving downward after receiving to place qualified anchor rods on the transfer conveying mechanism 63, and a lifting position for moving upward after receiving to lift unqualified anchor rods. The receiving position of the receiving plate 7 is higher than each support wheel of the transfer conveying mechanism 63.

[0048] The top surface of the receiving plate 7 is used to support the anchor rod and is inclined. Since the marking machine 4 in this embodiment is located to the right of the chamfering machine 2, and the chamfering conveying mechanism 61, the marking conveying mechanism 62 and the transfer conveying mechanism 63 are arranged from left to right in sequence, the top surface of the receiving plate 7 gradually tilts downward from left to right. When the receiving plate 7 receives the anchor rod, the anchor rod rolls to the right along the top surface of the receiving plate 7 under its own weight.

[0049] Each rejection unit also includes a movable stop that works in conjunction with the receiving plate 7 and a control mechanism that controls the movement of the movable stop. Specifically, the movable stop is a movable baffle 8. In this embodiment, the movable baffle 8 is a right trapezoid, but in other embodiments it can also be a rectangle. The movable baffle 8 has a stop position that is higher than the top surface of the receiving plate 7 to stop the anchor rod, and a clearance position that moves to allow the unqualified anchor rod to roll down along the top surface of the receiving plate 7.

[0050] Furthermore, the movable baffle 8 is guided and installed on the receiving plate 7 in the vertical direction. An elastic element is provided between the movable baffle 8 and the receiving plate 7 to deform under force when the movable baffle 8 moves downward, thereby providing power for the movable baffle 8 to reset upward. The above-mentioned control mechanism includes a pulling member connected between the movable baffle 8 and the fixed housing (i.e., cylinder 91) of the lifting mechanism. The pulling member is specifically a pull rope 10, which passes through the guide plate 17. The pull rope 10 has a relaxed, non-straightened state when the movable baffle 8 is in the stop position, and a straightened state that is gradually straightened during the process of the receiving plate 7 moving upward to the top position, so as to pull the movable baffle 8 downward relative to the receiving plate 7 to the clearance position.

[0051] Specifically, such as Figure 5 and Figure 6 As shown, the receiving plate 7 is provided with a guide groove 71, which includes a side wall and a bottom wall. The movable baffle 8 extends into the guide groove 71 and is guided and engaged with the side wall. The elastic element is a spring 11 disposed between the bottom wall and the bottom surface of the movable baffle 8. A through hole 72 is provided on the bottom wall. One end of the pull rope 10 is fixedly connected to the bottom surface of the movable baffle 8, and the other end passes through the through hole 72 and is fixedly connected to the cylinder 91. When the pull rope 10 is in a slack, non-stretched state, the movable baffle 8 is in a stopped position under the action of the spring 11.

[0052] like Figure 3 As shown, in the projection plane perpendicular to the anchor rod axis, the guide rod 16 and the movable baffle 8 are located on both sides of the connection between the telescopic rod 92 and the receiving plate 7, that is, the guide rod 16 is located on the left side of the telescopic rod 92 and the pull rope 10 is located on the right side of the telescopic rod 92, which is a relatively compact structure.

[0053] The working principle of the rod processing equipment in this utility model is as follows:

[0054] First, the chamfering machine 2 chamfers each anchor rod individually, and then the marking machine 4 marks each anchor rod individually. Simultaneously, the distance measuring device 5 measures the length of each anchor rod. After marking and length measurement, the anchor rods (including those with acceptable lengths and those with unacceptable lengths) are transferred one by one to the receiving plate 7 via the second transfer device 32. At this time, the receiving plate 7 is in the receiving position, the movable baffle 8 is in the stopping position, and the pull rope 10 is in a slack state. The anchor rods falling onto the receiving plate 7 roll to the right under their own weight until they stop against the movable baffle 8, preventing them from coming off. If the anchor rod is of acceptable length, the lifting cylinder 9 controls the receiving plate 7 to move downwards. When it descends to a certain level, the anchor rod can be placed on the support wheels of the transfer conveyor mechanism 63 and then transported to the next process. If the anchor rod is of unqualified length, the lifting cylinder 9 controls the receiving plate 7 to move upward. During the process, the receiving plate 7 and the movable baffle 8 move upward together first, and the pull rope 10 is gradually straightened. After straightening, as the receiving plate 7 continues to move upward, the pull rope 10 will pull the movable baffle 8 to move downward relative to the receiving plate 7. During the process, the spring 11 is compressed. When the movable baffle 8 moves to the clearance position, the movable baffle 8 is completely retracted into the guide groove 71, and the anchor rod can roll to the right along the top surface of the receiving plate 7 under its own weight, thereby realizing the removal of unqualified anchor rods.

[0055] After the receiving plate 7 moves to the lowering position and places the qualified anchor rod onto the transfer conveyor mechanism 63, it can move upward to the receiving position to wait for receiving the next anchor rod. At the same time, after the receiving plate 7 moves to the lifting position and the unqualified anchor rod rolls off the receiving plate 7, the receiving plate 7 can move downward to the receiving position to wait for receiving the next anchor rod.

[0056] In practical applications, a dedicated storage rack for defective products can be installed on the frame 15. Defective anchor rods rolling off the receiving plate 7 can fall onto this rack. Additionally, when the ranging device 5 detects an anchor rod with an unacceptable length, an alarm can be triggered to alert the operator. The operator manually controls the lifting cylinder 9 to move the receiving plate 7 to the top position. For normal, acceptable anchor rods, the controller operates the lifting cylinder 9, automatically switching between the receiving and lowering positions. Alternatively, the ranging device 5 and the lifting cylinder 9 can be linked. When the ranging device 5 detects an anchor rod with an acceptable or unacceptable length, it sends a signal to the controller. The controller then controls the lifting cylinder 9 based on the feedback signal, switching the receiving plate 7 to either the lowering or top position, requiring no manual intervention.

[0057] In summary, the rod removal device of this utility model can automatically remove unqualified rods with high efficiency, eliminates the need for manual handling, and solves the problems of reduced production efficiency and high labor intensity caused by manual handling.

[0058] Example 2 of the rod processing equipment of this utility model:

[0059] like Figure 7 As shown, unlike Embodiment 1, the specific form of the pulling component is different. In this embodiment, the pulling component includes a fixed rod 12 that is fixed to the movable baffle 8 and extends vertically downward. The pulling component also includes two connecting rods that are hinged together, namely a first connecting rod 13 and a second connecting rod 14. The first connecting rod 13 is hinged to the end of the fixed rod 12, and the second connecting rod 14 is hinged to the cylinder body 91. The fixed rod 12 passes through a through hole in the bottom wall of the guide groove 71. When the movable baffle 8 is in the stopped position, the hinged part of the fixed rod 12 and the first connecting rod 13 is located below the through hole, and the first connecting rod 13 and the second connecting rod 14 are in a folded state. At the same time, a relatively large clearance hole is provided on the guide plate to avoid interference with the first connecting rod 13 and the second connecting rod 14.

[0060] In this embodiment, when the anchor bolt length is not up to standard, as the receiving plate 7 moves upward, the first connecting rod 13 and the second connecting rod 14 gradually straighten. After straightening, the movable baffle 8 can be pulled downward relative to the receiving plate 7 to the clearance position. When the receiving plate 7 moves downward, the movable baffle 8 moves upward relative to the receiving plate 7 to the stop position, and the first connecting rod 13 and the second connecting rod 14 are folded again.

[0061] Example 3 of the rod processing equipment of this utility model:

[0062] like Figure 8 As shown, unlike Embodiments 1 and 2, this embodiment does not include a pulling component capable of straightening, loosening, or folding. Instead, the control mechanism is directly set as a telescopic cylinder 18 fixed to the receiving plate 7. The piston rod of the telescopic cylinder 18 passes through the bottom wall of the guide groove and is fixedly connected to the movable baffle 8. When the anchor rod is defective, the telescopic cylinder 18 directly controls the movable baffle 8 to move downward to the clearance position, and the defective anchor rod can roll down along the top surface of the receiving plate 7. After rolling down, the telescopic cylinder 18 then controls the movable baffle 8 to move upward to the stop position. In this embodiment, the receiving plate 7 does not need to move upward after receiving the material; it only has two positions: the receiving position and the descending position. Of course, the telescopic cylinder 18 can also be replaced with a hydraulic cylinder or an electric push rod, with the same effect.

[0063] Example 4 of the rod processing equipment of this utility model:

[0064] like Figure 9 As shown, unlike the above embodiments, the movable baffle 8 in this embodiment is not guided and installed on the receiving plate 7 in the vertical direction, but is hinged to the receiving plate 7. At this time, one end of the telescopic cylinder 18 is hinged to the receiving plate 7, and the other end is hinged to the movable baffle 8. By controlling the swing of the movable baffle 8, the movable baffle 8 has a blocking position and a yielding position.

[0065] In other embodiments of the rod processing equipment: the movable stop can also be a movable block or a movable stop bar, and the material receiving part can also be a material receiving bar.

[0066] In other embodiments of the rod processing equipment: the lifting cylinder that controls the up and down movement of the receiving part can also be replaced by a hydraulic cylinder or an electric push rod. Of course, in other embodiments, a screw and nut mechanism or a crank and slider mechanism that can output linear motion can also be used to control the up and down movement of the receiving part.

[0067] In other embodiments of the rod processing equipment: in a projection plane perpendicular to the rod axis, the guide rod and the movable stop can be located on the same side of the connection between the telescopic rod and the receiving part.

[0068] In other embodiments of the rod processing equipment: when guide rods and guide plates are present, one end of the pull rope can also be connected to the guide plate without having to pass through the guide plate and be fixedly connected to the cylinder of the lifting mechanism. Similarly, if a folding linkage is used, the outermost link can also be hinged to the guide plate without having to pass through the guide plate and be hinged to the cylinder of the lifting mechanism.

[0069] In other embodiments of the rod processing equipment: when a pull rope is used to control the movement of the movable stop, the end of the pull rope away from the movable stop can be directly fixedly connected to the frame. Similarly, when a folding linkage is used as the control mechanism, the outermost linkage can be directly hinged to the frame.

[0070] In other embodiments of the rod processing equipment: when a folding linkage is used as the control mechanism, in addition to the fixed rod, there can be three or four or more linkages that are hinged together in sequence. In this case, one of the linkages at both ends is hinged to the fixed rod, and the other fixed rod is hinged to the fixed housing of the frame or lifting mechanism.

[0071] In other embodiments of the rod processing equipment: the receiving part may not have a guide groove. The guiding method between the receiving part and the movable stop part can be through dovetail groove guidance or T-slot guidance. In this case, a support plate can be fixed on the receiving plate to support the spring, so that the spring rests between the movable stop part and the support plate. The spring is still a compression spring. Of course, the spring can also be a tension spring. The tension spring is connected between the movable stop part and the receiving part. When the movable stop part moves downward relative to the receiving part, the tension spring is stretched.

[0072] In other embodiments of the rod processing equipment: when a folding linkage is used as the control mechanism, the folding linkage may include only two hinged connecting rods, one of which is directly hinged to the movable stop, and the other is hinged to the fixed housing of the frame or lifting mechanism; or the folding linkage may include three connecting rods, one of which is hinged to the movable stop, and the other is hinged to the fixed housing of the frame or lifting mechanism; when the folding linkage includes four or more connecting rods, one of which is hinged or fixed to the movable stop, and the other is hinged or fixed to the fixed housing of the frame or lifting mechanism.

[0073] In other embodiments of the rod processing equipment: the elastic element can also be replaced with a rubber sleeve or a bent spring sheet.

[0074] In other embodiments of the rod processing equipment: the number of rejection units depends on the specific number of support wheels in the transfer device, but there should be at least two to meet the material receiving function.

[0075] In other embodiments of the rod processing equipment: the length measuring device can also be arranged at the end opposite to the chamfering machine. In this case, after chamfering, unqualified anchor rods are rejected. The transfer device is used to transfer the anchor rods on the chamfering conveyor to the receiving part. If the anchor rod is qualified, the receiving part moves down and the anchor rod is placed on the marking conveyor. If the anchor rod is unqualified, the receiving part moves up or the control mechanism controls the movable stop to move to the clearance position and the anchor rod rolls down along the top surface of the receiving part. In this case, a non-conforming product storage rack needs to be set up next to the chamfering conveyor.

[0076] In other embodiments of the rod processing equipment: the length measuring device can be arranged before chamfering and marking, that is, the length of the anchor rod is first detected, and the qualified anchor rods are then chamfered and marked in sequence. The unqualified anchor rods are directly rejected. At this time, the structure of the feeding device changes accordingly. The feeding device includes a storage rack and a flipping rack. The storage rack is used to store the anchor rods, and the flipping rack is used to lift the anchor rods upward. The anchor rods slide down along the flipping rack onto the receiving component. If the anchor rod is qualified, the receiving component moves down and the anchor rod is placed directly on the chamfering conveying mechanism. If the anchor rod is unqualified, the receiving component moves up or the control mechanism controls the movable stop to move to the clearance position and the anchor rod rolls down along the top surface of the receiving component.

[0077] In other embodiments of the rod processing equipment: the rod processing equipment may also be equipped with a detection device for detecting other physical quantities, such as a detection device for detecting parameters such as diameter, straightness or cylindricity, and in this case, the above-mentioned rod rejection device is also configured.

[0078] In other embodiments of the rod processing equipment: the rod can also be a steel pipe or a solid round steel bar, in which case the rod processing equipment is a steel processing equipment, such as a processing equipment for cutting and grinding steel pipes or solid round steel bars.

[0079] The embodiment of the rod removal device in this utility model is as follows: the specific structure of the rod removal device is the same as that of the rod removal device in any embodiment of the rod processing equipment described above, and will not be repeated here.

[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
