AI Technical Summary
During the pipe production process, multiple steel pipes tend to accumulate during the material transfer process, which makes the loading operation of subsequent processing steps inconvenient. Especially when the pace of the previous processing step is faster than that of the next processing step, the steel pipes accumulate and squeeze each other in the material removal position.
A ratchet feeding mechanism is adopted, which includes two groups of ratchet feeding components symmetrically distributed on the left and right. Each group of components consists of a bearing seat bracket, a rotating shaft, a pulling disc, a ratchet and a pawl driving component. The pulling disc is locked and unlocked by inserting and withdrawing the pawl from the ratchet tooth groove to ensure the sequential rolling of single pipes.
It achieves stable feeding of a single pipe, avoids the accumulation of multiple pipes at the feeding position, and ensures smooth feeding of subsequent processing steps.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe production and processing, in particular to a ratchet material shifting mechanism and a ratchet material shifting tool for separating the flow of single pipes. Background Art
[0002] As a kind of pipe material, steel pipe is usually produced on an automated assembly line during its production and processing, which includes multiple production processes. The steel pipe needs to flow between the processing stations of different production processes.
[0003] To this end, a material transfer mechanism is usually added between the previous processing station and the next processing station to move the pipe that has completed the previous process a certain distance so that it can be moved to the next processing station or the designated material collection position of the next processing station.
[0004] In some assembly lines, a pipe rack with an angled upper end surface is used as a material transfer mechanism. The steel pipe first completes the previous processing step in the previous processing station before being fed into the material transfer mechanism. Specifically, the steel pipe that has completed the previous processing step is lowered from the high point of the pipe rack's upper end surface. With the help of gravity, the steel pipe rolls down the upper end of the pipe rack from the high point to the low point and enters the designated material removal position (unloading position) at the low point, thereby achieving self-movement of the lateral spacing. When the next processing station is free, the steel pipe in the designated material removal position will be removed and sent to the next processing station for the next processing step.
[0005] In some assembly line production processes, multiple steel pipes cannot be fed into the same processing station at once, and the previous processing step is faster than the next. Therefore, a steel pipe may not be able to be fed into the next processing station quickly after completing the previous step and must wait until the next processing station is free. Before the next processing station becomes free, the previous processing station may have already processed multiple steel pipes. At this point, if the first pipe in the unloading station has not been removed and a second pipe that has completed the previous process is fed into the pipe rack, the second pipe will roll down the pipe rack to the unloading station, colliding with and squeezing the pipes already in the unloading station. Multiple steel pipes will be squeezed together and temporarily piled up at the designated unloading station, hindering loading operations for the next processing step (for example, multiple steel pipes squeezed together can easily squeeze the previous pipe, making it difficult to clamp the previous pipe). Utility Model Content
[0006] The present utility model aims to provide a ratchet feed mechanism and a ratchet feed fixture for separating the flow of individual pipes. This solves the existing technical problem of multiple pipes entering the upper end of a pipe rack and rolling down the rack, which can easily lead to a pile-up of pipes at the low point of the feed point. The present utility model has a simple structure and lowers costs.
[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0008] A ratchet material shifting mechanism includes two groups of ratchet material shifting components that are symmetrically distributed on the left and right sides;
[0009] Each ratchet shifting assembly comprises a bearing seat bracket, a rotating shaft, a pull disc, a ratchet, a pawl, and a pawl driving component for driving the pawl to insert into and withdraw from the tooth groove of the ratchet; the pull disc and the ratchet are connected to the outer wall of the rotating shaft; when the rotating shaft rotates, the pull disc and the ratchet rotate synchronously with the rotating shaft; a plurality of dial grooves are provided along the circumference of the outer edge of the pull disc; a bearing is provided at the upper end of the bearing seat bracket, and the rotating shaft is placed in the bearing;
[0010] It also includes a shaft driving component for driving the shaft to rotate.
[0011] Furthermore, it also includes a pawl fixing support fixedly connected to the bearing seat bracket, one end of the pawl is hinged to the pawl fixing support; the pawl driving component is a pawl pushing cylinder; the pawl pushing cylinder is fixedly connected to the bearing seat bracket, and the moving end of the pawl pushing cylinder is connected to the pawl.
[0012] A ratchet material shifting tool for separating the flow of a single pipe comprises the ratchet material shifting mechanism and two pipe racks distributed on the left and right sides of the ratchet material shifting mechanism; the upper ends of the pipe racks are higher at the rear and lower at the front, and have an inclined angle.
[0013] Furthermore, a limit block is provided at the front end of the pipe rack, and the limit block protrudes from the upper end surface of the pipe rack.
[0014] Compared with the prior art, the present invention provides a ratchet material shifting mechanism and a ratchet material shifting tool for separating the flow of a single pipe, which has the following beneficial effects:
[0015] In the present invention, a ratchet feeding mechanism is used to implement the pipe feeding operation. A puller and ratchet are connected to the outer wall of a rotating shaft. When the rotating shaft rotates, the puller and ratchet are driven to rotate synchronously. During operation, the pipe can be placed behind the puller, and the ratchet feeding mechanism pulls the pipe forward. When the pawl is driven by a pawl driving component and inserted into the tooth groove of the ratchet, it locks the ratchet so that the ratchet cannot continue to rotate forward. At this time, the rotating shaft and the puller are also unable to continue to rotate forward, and the puller is in a locked state. When the puller is in the locked state, the rotating shaft driving component stops driving the rotating shaft. When the pawl is driven by the pawl driving component and exits the tooth groove of the ratchet, the puller is in an unlocked state. The rotating shaft can continue to rotate under the drive of the rotating shaft driving component, thereby driving the puller to continue to rotate forward.
[0016] The outer edge of the puller is circumferentially defined by several dial grooves. When two pipes are simultaneously rolled down the rear side of the puller at the top of the pipe rack, the first pipe will first roll into one of the puller's dial grooves. After the first pipe enters a dial groove, the puller is unlocked from its locked state, the shaft drive is activated, and the puller rotates, pushing the first pipe in the dial groove forward. Simultaneously, the second pipe behind it enters the next dial groove. After the second pipe enters the next dial groove, the puller is locked from its unlocked state, preventing the second pipe from rolling further. After the first pipe is removed and transferred to the next processing station, the puller is unlocked from its locked state, the shaft drive is activated, and the dial rotates, pushing the second pipe toward the lower point of the pipe rack. Through the above operation, the material movement of a single pipe can be realized, and the front and rear pipes can be separated during the material movement, so that the front and rear pipes can roll down separately in sequence, avoiding the two pipes rolling down at the same time and piling up next to each other in the material removal position at the low point.
[0017] At the same time, there are two sets of ratchet material shifting components in the ratchet material shifting mechanism. The two sets of ratchet material shifting components are distributed on the left and right, and a total of two pulling discs are included. Two different parts of the outer wall of the same pipe will be supported by the two pulling discs at the same time. The two pulling discs can achieve more stable support for the pipe on the pipe rack. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] like Figure 1-6 As shown, the present invention provides a ratchet material dispensing tool for separating the flow of a single pipe. The ratchet material dispensing tool for separating the flow of a single pipe comprises a ratchet material dispensing mechanism and two pipe racks 20 distributed on the left and right sides of the ratchet material dispensing mechanism. Figure 4 As shown, two pipe racks 20 are arranged parallel to each other, with the upper end of the pipe rack 20 being higher at the back and lower at the front, and having an inclined angle. A support base 21 is connected to the lower end of each pipe rack 20.
[0029] like Figure 1 The ratchet shifting mechanism in this embodiment is shown in FIG. 1 , which includes two groups of ratchet shifting assemblies symmetrically distributed on the left and right sides and a group of rotating shaft driving components. Figure 7 shown.
[0030] Specifically, if Figure 7 As shown, in this embodiment, each ratchet-pulling assembly includes a bearing support 1, a rotating shaft, a puller 3, a ratchet 4, a pawl 5, and a pawl driving component that drives the pawl 5 into the tooth groove of the ratchet 4. The puller 3 and the ratchet 4 are connected to the outer wall of the rotating shaft. When the rotating shaft rotates, the puller 3 and the ratchet 4 rotate synchronously with the rotating shaft.
[0031] In this embodiment, each rotating shaft is composed of a connecting shaft 2 and a transmission shaft 16. Figure 1 、 3As shown, specifically, a bearing 8 is provided at the upper end of each bearing seat bracket 1. The bearing 8 is a spherical bearing with a vertical seat. The connecting shaft 2 is placed in the bearing 8, and the rear end of the connecting shaft 2 is connected to the end of the transmission shaft 16 through a connecting sleeve 9 and a pin 10. When the transmission shaft 16 rotates, it can drive the connecting shaft 2 to rotate synchronously.
[0032] In this embodiment, the rotating shaft driving component is a combination of a motor 26 and a reducer 17. Figure 1 As shown, the two sets of ratchet prying assemblies are symmetrically distributed on the left and right sides of the reducer 17, and the two transmission shafts 16 are connected to the reducer output shaft 18. During operation, after the motor 26 connected to the reducer 17 is started, it will drive the reducer output shaft 18 to rotate, thereby driving the two transmission shafts 16 at the left and right ends to rotate synchronously, and finally drive the two pullers 3 and two ratchets 4 in the two sets of ratchet prying assemblies to rotate synchronously.
[0033] In this embodiment, the pawl driving component is the pawl pushing cylinder 6. Figure 1 and Figure 5-7 As shown, in the ratchet feed assembly, a pawl fixing support 7 is fixedly connected to the bearing support 1. The upper end of the pawl fixing support 7 is provided with a pawl connecting end 15, and the rear end of the pawl 5 is hinged to the pawl connecting end 15. The lower end of the pawl pushing cylinder 6 is connected to the lower end of the pawl fixing support 7, thereby achieving a fixed connection between the pawl pushing cylinder 6 and the bearing support 1. At the same time, the front end of the movable end (i.e., the piston rod) of the pawl pushing cylinder 6 is connected to the middle part of the pawl 5. Under the push of the pawl pushing cylinder 6, the front end of the pawl 5 can be inserted into and out of the tooth groove of the ratchet wheel 4.
[0034] In this embodiment, when the pawl 5 is inserted into the tooth groove of the ratchet 4, the ratchet 4 cannot continue to rotate forward, and the rotating shaft driving component stops driving the rotating shaft. At this time, the ratchet 4 and the pull plate 3 are both in a locked state. Figure 5 shown.
[0035] On the contrary, when the pawl 5 exits the tooth groove of the ratchet wheel 4, the ratchet wheel 4 and the pull plate 3 are both in the unlocked state. Figure 6 When the puller 3 is unlocked, the motor 26 is activated, rotating the reducer output shaft 18, driving the two rotating shafts to rotate synchronously, thereby achieving synchronized rotation of the two pullers 3 within the two ratchet shifting assemblies. At this point, the pipe 22 is located in the puller groove 24. As the puller 3 rotates forward, the pipe 22 is pulled forward and rolls toward the low point on the upper end surface of the pipe rack 20.
[0036] At the same time, if Figure 4-5As shown, in this embodiment, the dial 3 has a four-pointed star structure, with a raised sharp corner between two adjacent dial grooves 24. Each dial 3 includes four sharp corners and four dial grooves 24. When the dial 3 is rolling, the front and rear pipes can be separated at the front and rear sides of the sharp corner.
[0037] like Figure 4 As shown, the front end of the pipe rack 20 is also equipped with a stopper 23, which protrudes from the upper end surface of the pipe rack 22. When the pipe 22 rolls down the pipe rack 22 under the push of the puller 3, it is blocked by the rear end of the stopper 23, preventing it from moving forward. The falling pipe can temporarily stay behind the stopper 23 (i.e., the material removal position) until the next workstation is available. The operator then uses the gripping component to transfer the pipe to the next workstation for processing.
[0038] If the front end of the pipe rack 20 is not provided with a limit stopper 23 , the material taking position is moved forward and is provided at the front side of the pipe rack 20 .
[0039] During the operation, the pipe 22 rolls down from the upper end of the pipe rack 20 and is stopped by the pull plate 3 in the locked state. After the pull plate 3 is unlocked, the rotating shaft driving component is started, and the pipe 22 is pushed forward and rolled down as the pull plate 3 rotates, and finally rolls to the rear side of the limit block 23.
[0040] like Figure 3 As shown, in this embodiment, the front end of the connecting shaft 2 penetrates both the ratchet 4 and the flange 13. A keyed connection is formed between the front outer wall of the connecting shaft 2, the ratchet 4, and the flange 13. The puller 3 is fixedly connected to the flange 13 via a second setscrew 25. Furthermore, a shaft end stopper 11 is provided on the front side of the puller 3 and secured to the end of the connecting shaft 2 via a first setscrew 12. This structure effectively connects the puller 3, the ratchet 4, and the connecting shaft 2, ensuring that the puller 3 and the ratchet 4 rotate synchronously with the connecting shaft 2 as the connecting shaft 2 rotates.
[0041] In this embodiment, a ratchet-driven mechanism is employed to achieve the material-switching operation of the tubular material 22. The puller 3 and ratchet 4 are connected to the outer wall of the end portion of the rotating shaft, specifically, to the outer wall of the front end of the connecting shaft 2. When the connecting shaft 2 rotates, the puller 3 and ratchet 4 are driven to rotate synchronously. Driven by a pawl drive component, the pawl 5 is inserted into the tooth groove of the ratchet 4, locking the ratchet 4 so that it cannot continue to rotate forward. At this point, the rotating shaft and the puller are also unable to rotate forward, resulting in the puller 3 being in a locked state. When the puller 3 is in the locked state, the rotating shaft drive component stops driving the rotating shaft. When the pawl 5 returns to its original position and exits the tooth groove of the ratchet, the puller 3 is unlocked, and the rotating shaft can continue to rotate under the drive of the rotating shaft drive component, thereby driving the puller 3 to continue to rotate forward.
[0042] The outer edge of the pull plate 3 is provided with four pull plate grooves 24 along the circumference. When two pipes (such as steel pipes) are rolled down from the rear side of the pull plate 3 on the pipe rack 20 at the same time, the first pipe will first roll into one of the pull plate grooves 24 on the pull plate 3 (such as the first pipe). Figure 4 As shown. After the first pipe rolls into the dial groove 24, the dial 3 is unlocked from the locked state, and the motor 26 is started, driving the dial 3 to rotate, pushing the first pipe in the dial groove 24 to roll forward. At the same time, the second pipe at the rear side will enter the next dial groove 24. After the second pipe at the rear side enters the next dial groove 24, the motor 26 stops, and the dial 3 is locked from the unlocked state. The second pipe is blocked by the dial 3 and cannot continue to roll. When the material removal position at the lowest point of the pipe rack is vacant (i.e., the first pipe has been removed and sent to the second processing position), the dial 3 is unlocked from the locked state, and the motor 26 is started, driving the dial 3 to rotate, pushing the second pipe further toward the lowest point of the pipe rack. Through the above operation, the material movement of a single pipe can be realized, and the front and rear pipes can be separated during the material movement, so that the front and rear pipes can roll down separately in sequence, avoiding the two pipes rolling down at the same time and accumulating at the lowest point of the pipe rack or the designated material removal position.
[0043] At the same time, there are two groups of ratchet material shifting components in the ratchet material shifting mechanism. The two groups of ratchet material shifting components are distributed on the left and right, and a total of two pulling discs 3 are included. Two different parts of the outer wall of the same pipe will be supported by the two pulling discs 3 at the same time. The two pulling discs 3 can achieve more stable support for the pipe on the pipe rack.
[0044] The ratchet feeder assembly for separating the flow of individual pipes in this embodiment is suitable for lateral movement of pipes during assembly line production. Furthermore, the ratchet feeder mechanism in this embodiment is also suitable for pipe racks with a shallow upper end face inclination angle. Because of this shallow upper end face inclination angle, pipes placed on the rack are less likely to automatically roll downward. In these situations, the ratchet feeder mechanism can effectively feed pipes at the upper end of the rack, allowing the rotation of the puller 3 to push the pipe 22 along the upper end face of the rack. Furthermore, the rotation rhythm of the puller 3 can be controlled to achieve the movement of individual pipes and control the rhythm of pipe delivery to the lower point of the rack.
