Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment and is a pipe feeding and conveying device. Background Technology

[0002] In the field of existing pipe processing equipment, pipe conveying is an essential step, including pipe loading mechanisms, primarily used for the automatic feeding of pipes. Existing pipe loading mechanisms, such as the invention entitled "A Pipe Billet Cutting System" published in Chinese patent literature (application publication number CN116160092A, publication date May 26, 2023), disclose an automatic pipe loading structure, mainly including a loading lifting inclined platform, a single-bracket feeder, and a roller conveyor. The pipe billet is automatically fed and flipped by the rotation of the single-bracket feeder. The structure is relatively simple and is the most common loading form in the prior art. However, the disadvantage of this type of loading mechanism is the lack of a pipe loading measurement mechanism. Many existing steel pipe processing equipment require adjusting the pipe processing position according to the pipe length; therefore, a corresponding pipe measuring device is needed to measure the pipe. For example, Chinese patent publication number CN202255215U, published on May 30, 2012, discloses a utility model entitled "A Steel Pipe Length Measuring Device," which uses rollers to measure the length of steel pipes. However, this structure requires the pipe to be transported axially, while the length measuring device remains stationary. This structure is suitable for general straight-line pipe transport but difficult to apply to lateral pipe loading. Furthermore, existing lateral pipe loading measurements mainly rely on photoelectric induction. However, photoelectric induction length measurement has two drawbacks: firstly, higher accuracy comes at a higher cost; secondly, for small-diameter long pipes, the long length and tendency to bend can obstruct the photoelectric signal, resulting in ineffective measurement or significant measurement errors. Therefore, improvements to existing lateral pipe loading and measurement structures are needed. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a pipe fitting feeding and conveying device that solves the technical problems of inconvenient pipe fitting measurement or large measurement errors during the transverse feeding of existing similar pipe fittings. This objective is achieved through the following technical solution.

[0004] A pipe fitting feeding and conveying device includes a conveying platform and a pipe fitting length measuring mechanism. The pipe fitting length measuring mechanism comprises a pipe end limiting bracket, a linear reciprocating conveyor, a cylinder A, and a roller measuring device. A pipe feeding support station is provided on one side of the conveying platform, providing obstruction support to the bottom and one side of the pipe fitting. The pipe end limiting bracket is fixed to one end of the conveying platform, providing axial limitation to one end of the pipe fitting. The linear reciprocating conveyor is positioned close to the pipe feeding support station and fixed to one side of the conveying platform. Cylinder A is fixed to the reciprocating platform of the linear reciprocating conveyor, and cylinder A is fixedly connected to the roller measuring device. Initially, the roller of the roller measuring device is away from the pipe fitting at the pipe feed support station. When cylinder A pushes the roller measuring device into position, the roller of the roller measuring device presses against the outer wall of the pipe fitting and is identified as starting measurement. As the roller measuring device moves in the linear direction with the linear reciprocating conveyor, the roller of the roller measuring device rolls along the linear direction of the pipe fitting and measures. When the roller of the roller measuring device rolls to the end of the pipe fitting and disengages, the roller of the roller measuring device loses pressure and is identified as ending measurement. This structure effectively realizes the length measurement of pipe fittings in the transverse movement station. Measurement only needs to start from a fixed point on the pipe fitting, resulting in high measurement efficiency. Furthermore, the roller measurement effectively presses and confines the pipe fitting within the pipe feed support station, reducing the error caused by pipe bending and ensuring accurate and reliable measurement.

[0005] The pipe length measuring mechanism includes a cylinder B, which is fixed to the pipe end limiting bracket. An electric pipe clamp is fixedly connected to the top rod of cylinder B, and the bottom of the electric pipe clamp engages with a slide rail at the bottom of the pipe end limiting bracket. When the electric pipe clamp grips the pipe at the pipe feeding support station, cylinder B pulls the electric pipe clamp into position, and one end of the pipe abuts against the pipe end limiting bracket, limiting the pipe length at which the limiting end of the pipe end limiting bracket is a fixed distance from the starting end of the roller measuring device. This structure ensures that one end of the pipe in the pipe feeding support station automatically aligns with the pipe end limiting bracket, guaranteeing the accuracy of the length measurement.

[0006] The pipe fitting feeding and conveying device includes a pipe fitting feeding mechanism, which includes a feeding and discharging bracket for obliquely conveying pipe fittings. At the end of the feeding and discharging bracket is a tilting assembly that, when rotated, transfers the pipe fittings at the end of the feeding and discharging bracket to the pipe feeding support station of the conveying platform. The tilting assembly includes a shaft, tilting plates evenly distributed along the shaft's axial direction, and a servo motor or power cylinder that drives the shaft to rotate. The servo motor or power cylinder is fixed to the feeding and discharging bracket, and the shaft rotates relative to the end of the feeding and discharging bracket in a positioning position. Initially, one end of the tilting plate is located below the pipe fitting at the end of the feeding and discharging bracket. When the tilting plate rotates to its position, it lifts the pipe fitting at the end of the feeding and discharging bracket, and the pipe fitting rolls along the tilting plate to the pipe feeding support station. When the tilting plate swings to its position, the other end of the tilting plate limits one side of the pipe fitting in the pipe feeding support station. This structure enables automatic feeding of pipe fittings. When the pipe fitting is in place, the tipping plate temporarily limits the pipe fitting, effectively preventing it from bouncing off the pipe feeding support station during feeding.

[0007] The tipping plate rotates in one direction or reciprocates, and the end of the feeding and discharging bracket is equipped with a baffle bracket to block the end pipe fittings. This structure improves the stability of pipe fitting feeding.

[0008] The material-stopping bracket includes a motor, a multi-link, a crossbar, a swing arm, a swing rod, a swing rod seat, and a stop rod. The motor is fixed to the feeding and discharging bracket. The motor output shaft is connected to the crossbar via the multi-link. The crossbar is connected to at least two swing arms, each swing arm being connected to a swing rod. The swing rod is rotatably positioned at the swing rod seat, which is fixed to the feeding and discharging bracket. Each swing rod is fixedly connected to a stop rod. When the motor rotates forward to its final position, the motor moves axially along the crossbar via the multi-link. The crossbar drives the swing arm and swing rod to rotate relative to the swing rod seat. The swing rod drives the stop rod to form a tight stop on the second-to-last pipe fitting at the end of the feeding and discharging bracket. When the motor rotates in reverse to its final position, the stop rod resets, releasing the stop on the pipe fitting, which then rolls to the end of the feeding and discharging bracket. This structure is a specific implementation of a pipe fitting material-stopping bracket, making pipe feeding more stable and reliable, and reducing the likelihood of pipe jamming.

[0009] The overall structure of this utility model is relatively simple, effectively realizing the transverse feeding and length measurement of pipe fittings. The length measurement is relatively stable, with small error and high accuracy, and the measurement is relatively efficient. It is suitable for use as a feeding and measuring device for various types of pipe fittings, or as an improvement on similar pipe fitting length measuring structures. Attached Figure Description

Implementation

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] like Figures 1-5 As shown, the pipe fitting feeding and conveying device includes a pipe fitting feeding mechanism 4 and a pipe fitting length measuring mechanism 2. The pipe fitting feeding mechanism includes a feeding and discharging bracket 401 with inclined conveying of pipe fittings. At the end of the feeding and discharging bracket, there is a turning component 3 that, when rotated, transfers the pipe fittings at the end of the feeding and discharging bracket to the pipe feeding support station 101 on one side of the conveying platform 1. The turning component includes a shaft, turning plates 302 evenly distributed along the shaft axis, and a power cylinder 301 that drives the shaft to rotate. The power cylinder is fixed to the feeding and discharging bracket, and the shaft rotates in a positioning position relative to the end of the feeding and discharging bracket. In the initial state, one end of the turning plate is located below the pipe fitting 5 at the end of the feeding and discharging bracket; when the turning plate rotates to the correct position, the turning plate lifts the pipe fitting at the end of the feeding and discharging bracket, and the pipe fitting rolls along the inclined surface of the turning plate into the pipe feeding support station. The other end of the turning plate limits one side of the pipe fitting in the pipe feeding support station to prevent the pipe fitting from rolling in and popping out.

[0018] To make the material turning operation of the turning plate 302 more reliable, the end of the aforementioned feeding and discharging bracket 401 is provided with a blocking bracket to block the pipe at the second-to-last pipe station. The blocking bracket includes a motor 402, a multi-link 403, a crossbar 404, a swing arm 405, a swing rod 406, a swing rod seat 407, and a stop rod 408. The motor is fixed to the feeding and discharging bracket, and the motor output shaft is connected to the crossbar through the multi-link. The crossbar is connected to at least two swing arms, and each swing arm is connected to a swing rod. The swing rod is rotated and positioned at the swing rod seat, and the swing rod seat is fixed to the feeding and discharging bracket. Each swing rod is fixedly connected to the stop rod. When the motor rotates forward to the correct position, the motor moves axially through the multi-link, and the crossbar drives the swing arm and the swing rod to rotate relative to the swing rod seat. The swing rod drives the stop rod to form a tight stop on the second-to-last pipe at the end of the feeding and discharging bracket. When the motor rotates in reverse to the correct position, the stop rod resets and releases the stop on the pipe, and the pipe rolls to the end of the feeding and discharging bracket. The main purpose of this structure is to prevent the pipe fittings from interfering with the turning plate when it rotates. Therefore, a limit is needed on the second to last pipe fitting to leave space for the turning plate to rotate.

[0019] The pipe length measuring mechanism of the pipe feeding and conveying device includes a pipe end limiting bracket 201, an electric pipe clamp 206, a cylinder A 203, a linear reciprocating conveyor 202, a cylinder B 205, and a roller measuring device 204. A horizontal angle steel is provided on one side of the conveying platform 1 as a pipe feeding support station 101, which provides blocking support to the bottom and one side of the pipe. The linear reciprocating conveyor is a chain-type reciprocating mechanism or an electric cylinder-type reciprocating mechanism; this is an existing mechanism and will not be described in detail. The linear reciprocating conveyor is positioned near the pipe feeding support station and fixed to one side of the conveying platform. Cylinder A is fixed to the reciprocating platform of the linear reciprocating conveyor, and cylinder A is fixedly connected to the roller measuring device. In the initial state, the roller of the roller measuring device is far away from the pipe fitting 5 at the pipe feeding support station; when the cylinder A pushes the roller measuring device into place, the roller of the roller measuring device presses against the outer wall of the pipe fitting and is identified as the start of measurement. When the roller measuring device moves in the linear direction with the linear reciprocating conveyor, the roller of the roller measuring device rolls along the linear direction of the pipe fitting and measures; when the roller of the roller measuring device rolls to the end of the pipe fitting and disengages, the roller of the roller measuring device loses pressure and is identified as the end of measurement. The aforementioned pipe end limiting bracket is fixed to one end of the conveying platform and forms an axial limit on one end of the pipe fitting at the pipe feeding support station. Cylinder A is fixed to the pipe end limiting bracket, and the top rod end of cylinder A is fixedly connected to an electric pipe clamp. The bottom of the electric pipe clamp cooperates with the slide rail of the pipe end limiting bracket. When the electric pipe clamp clamps the pipe fitting at the pipe feeding support station, cylinder A pulls the electric pipe clamp into place, and one end of the pipe fitting abuts against the pipe end limiting bracket for limitation. The distance between the limiting end of the pipe end limiting bracket and the pipe fitting length at the starting end of the roller measuring device is a fixed value. Through this design, the travel of the roller measuring device is reduced, and the measuring efficiency is improved.

[0020] The working method of the pipe fitting feeding and conveying device is as follows: a batch of pipe fittings 5 ​​are placed into the feeding and discharging bracket 401 to form a discharge. The flipping plate 302 of the pipe fitting feeding mechanism swings back and forth to realize the automatic flipping of the pipe fittings at the end of the feeding and discharging bracket and guides them into the pipe feeding support station 101 of the conveying platform 1. During the introduction, the end of the flipping plate forms a temporary limiting support for the pipe fittings in the pipe feeding support station to prevent the pipe fittings from popping out instantly when they fall. After the pipe fittings are stabilized, the electric pipe clamp 206 clamps the pipe fittings, and the cylinder B205 pulls the electric pipe clamp so that one end of the pipe fitting abuts against the pipe end limiting bracket. After the pipe end is in position, cylinder A203 of the pipe length measuring mechanism drives the roller measuring device 204 to press against the pipe wall, indicating the start of measurement. A linear reciprocating conveyor then drives cylinder A and the roller measuring device to move axially along the pipe until the roller of the measuring device disengages from the pipe end, indicating the end of measurement. The linear reciprocating conveyor and cylinder A then reset the roller measuring device, completing the pipe length measurement. The measured pipe continues to be transported laterally to the next processing station via other conveying structures.

[0021] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Any obvious improvements or substitutions made to this utility model by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of this utility model.
