Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation equipment, and in particular to a fully automatic pipe feeding device and a control method thereof. Background Art

[0002] In the production and processing of pipes, the feeding link is a crucial basic step. Its efficiency and accuracy directly affect the operating efficiency, product quality and production cost of the entire production line. The traditional pipe feeding method mainly relies on manual operation or simple mechanical assistance, which has many disadvantages.

[0003] In terms of manual loading, workers need to manually carry the pipes and place them in designated locations, which is a very labor-intensive process. Long-term repetitive handling can easily make workers tired, which not only reduces work efficiency, but may also cause inaccurate placement of pipes due to human negligence or cause scratches and bumps on the surface of the pipes during handling, affecting the appearance quality and internal performance of the pipes, thereby reducing the qualified rate of the products. Moreover, with the continuous increase in labor costs, the economic cost of manual loading has gradually become a heavy burden for enterprises.

[0004] Although some simple mechanically assisted feeding devices have reduced the labor intensity of workers to a certain extent, they still have problems with single functions and low automation. For example, some devices can only realize simple transmission of pipes, and cannot effectively sort, accurately position and orderly stack the pipes. When faced with pipes of different specifications and different quality requirements, it is difficult to meet diverse production needs. When it is necessary to package the pipes, additional equipment and manual operation are often required, which not only increases equipment investment and floor space, but also makes the connection between the entire feeding and packaging process not smooth enough, which is prone to delays and errors.

[0005] In addition, in the traditional feeding process, there is a lack of accurate monitoring and effective protection mechanism for the pipe feeding process. Since it is impossible to accurately grasp the movement position and status of the pipe in real time, once abnormal conditions such as pipe blockage and slippage occur, it is impossible to detect and take corresponding measures in time, which can easily lead to equipment failure or even safety accidents. At the same time, frequent collisions between pipes and various parts of the feeding device will also cause wear and tear on the equipment, shorten the service life of the equipment, and increase the cost of equipment maintenance and replacement.

[0006] In summary, the traditional pipe feeding method can no longer meet the requirements of modern pipe production and processing industry for high efficiency, precision, automation and low cost. Therefore, it is of great practical significance and market demand to develop a feeding device that can realize full-automatic pipe feeding, has multiple functions and operates stably and reliably. The full-automatic pipe feeding device of the present invention is an innovative solution proposed to solve the above problems. Summary of the invention

[0007] The present invention aims to provide a device that can realize fully automatic feeding of pipes and has the functions of efficient sorting, precise positioning, and stable packaging, so as to improve the feeding efficiency in the pipe processing process, reduce labor costs, and ensure the stability and accuracy of the pipes in the entire feeding and subsequent processing process.

[0008] Overall structure

[0009] The device is assembled into a feeding mechanism by splicing three groups of feeding components. Each group of feeding mechanisms includes a vertically inclined column, the lower side wall of the column is horizontally connected to a support beam, a material blocking column is vertically arranged at the end of the support beam, and a feeding crossbeam is horizontally arranged on one side of the material blocking column. An inclined support frame is placed obliquely on the top of the feeding crossbeam, and a guide shaft rail for supporting the pipe and facilitating its sliding is installed on the top of the inclined support frame. A feeding blocking part is placed obliquely at the top position of the end of the feeding crossbeam.

[0010] Sorting and limiting components

[0011] The side wall of the diagonal support frame is hinged to the feeding cylinder, and the end of the feeding cylinder output shaft is hinged to the sorting baffle, which is also hinged to the side wall of the diagonal support frame. A limit bracket is provided on the top of the sorting baffle. The telescopic action of the feeding cylinder drives the sorting baffle to rotate, and then the limit bracket is used to control the stepping sliding of the pipe on the guide shaft rail, which can realize the sorting and precise positioning of the pipe, ensuring that the pipe enters the subsequent process in the predetermined order and position.

[0012] Material blocking and pushing components

[0013] A lifting cylinder is installed on the side wall of one end of the feeding beam away from the feeding blocking part, and the output end of the lifting cylinder is connected to the material blocking assembly. The material blocking assembly includes a material blocking damping block, a material pushing cylinder is arranged on the top of the material blocking damping block, and a material pushing damping block and a material pushing block are arranged at the end of the material pushing cylinder. The material blocking damping block can prevent the pipe from excessive movement. The pushing cylinder and the pushing block can cooperate to push the pipe evenly into the silo when needed, and the pushing damping block can buffer the impact force during the pushing process to protect the pipe and the device.

[0014] Packing tape related structure

[0015] The material belt reel is hinged under the feeding crossbeam, and the material belt reel is coaxially connected to the rotating shaft, and the ends of the rotating shaft are connected by a coupling. The top of the column and the material belt reel are wound with the same strapping belt, and the bottom of the strapping belt slides against the guide wheel, which is hinged to the upper side wall of the material blocking column. It also includes a motor, and the end of the motor output shaft and the rotating shaft sleeve are provided with a sprocket transmission group for driving the material belt reel to rotate. The strapping operation of the pipe in the silo can be realized by the motor drive.

[0016] Auxiliary parts

[0017] The first swing arm limit switch is installed on the side wall of one end of the diagonal support frame close to the feeding blocking part, and the second swing arm limit switch is installed on the side wall at the middle position, which is used to monitor the position and movement state of the pipe on the diagonal support frame, so as to timely feedback the signal to the control system to adjust the action of each component. The strapping sleeve is equipped with a blocking plate to ensure the accurate working position of the strapping belt. The side wall of the column, the top of the support beam and the side wall of the material blocking column are all equipped with material storage shock-absorbing blocks to reduce the impact caused by the collision between the pipe and the device. Each set of feeding mechanisms is fixedly connected by two connecting column bolts to ensure the stability of the entire feeding device structure.

[0018] Beneficial Effects

[0019] 1. It realizes a fully automated operation process from the initial placement of pipes, step-by-step sliding, silo stacking to final packaging, without the need for a lot of manual intervention, greatly improving production efficiency and reducing labor costs.

[0020] 2. With the cooperation of the feeding cylinder and the sorting baffle, the pipes can be sorted according to actual needs, and the stepping sliding of the pipes on the guide shaft rails and the positioning in the silo can be accurately controlled to ensure that each pipe can accurately enter the predetermined position, providing a good foundation for subsequent processing.

[0021] 3. The material blocking assembly can not only effectively block the excessive movement of the pipe and prevent it from escaping from the feeding beam area, but also push the pipe into the silo smoothly when needed. In the process of blocking and pushing the material, the shock-absorbing block can buffer the impact force, thus protecting the quality of the pipe and the structural integrity of the device. At the same time, the distribution of the pipe in the silo is more evenly and reasonably, which is conducive to improving the packaging quality.

[0022] 4. The motor-driven strapping system can conveniently and quickly strap the pipes in the silo. With the assistance of the guide wheel and the blocking plate, the strapping can accurately strap around the pipes to ensure the firmness and stability of the strapping, which is convenient for the handling and storage of the pipes.

[0023] 5. The first swing arm limit switch and the second swing arm limit switch monitor the pipe feeding process in real time, detect abnormal conditions in time and feedback signals, so that the control system can adjust the actions of various components in time to ensure the safe and reliable operation of the entire device. The material storage shock absorber reduces the collision impact between the pipe and the various components of the device, prolongs the service life of the device, and reduces maintenance costs.

[0038] Installation and initial setup of the device

[0039] First, three groups of feeding components are spliced ​​and assembled to form a feeding mechanism. In each group of feeding components, the vertically inclined column 1 is fixedly installed at a suitable position in the workplace to ensure its stability. The support beam 2 is installed horizontally on the lower side wall of the column 1, and the material blocking column 4 is installed vertically at the end of the support beam 2. A feeding beam 22 is installed horizontally on one side of the material blocking column 4, and a diagonal support frame 13 is placed obliquely on the top of the feeding beam 22, and a guide shaft rail 14 for supporting the pipe and facilitating the sliding of the pipe is installed on the top of the diagonal support frame 13, and a feeding blocking part 12 is placed obliquely at the top end of the feeding beam 22.

[0040] The side wall of the diagonal support frame 13 is hinged to the feeding cylinder 17, the end of the output shaft of the feeding cylinder 17 is hinged to the sorting baffle 18, and the sorting baffle 18 is hinged to the side wall of the diagonal support frame 13, ensuring that the limit bracket 181 on the top of the sorting baffle 18 can normally play the role of limiting the movement position of the pipe. The material storage shock-absorbing blocks 21 are installed on the side walls of the column 1, the support beam 2 and the material blocking column 4.

[0041] The material belt reel 10 is hinged under the feeding cross beam 22, so that the material belt reel 10 is coaxially connected to the rotating shaft 9, and the ends of the rotating shaft 9 are connected through a coupling. The same packing belt 5 is wound around the top of the column 1 and the material belt reel 10, and a guide wheel 11 hinged to the upper side wall of the material blocking column 4 is set at the bottom of the packing belt 5, so that the packing belt 5 can smoothly slide against the guide wheel 11. The motor 7 is installed, and the end of the output shaft of the motor 7 and the rotating shaft 9 are sleeved with a sprocket transmission group 8 for driving the material belt reel 10 to rotate. The first swing arm limit switch 15 is installed on the side wall of one end of the diagonal support frame 13 close to the feeding blocking part 12, and the second swing arm limit switch 16 is installed on the side wall at the middle position of the diagonal support frame 13, and a blocking plate 6 is sleeved on the packing belt 5. The two connecting columns 3 are bolted and fixedly connected between each group of feeding mechanisms to complete the installation and initial setting of the entire device.

[0042] Pipe feeding operation

[0043] Initial stacking and positioning: The pipes are placed at the loading blocking portion 12 to be stacked there. At this time, due to the blocking effect of the loading blocking portion 12, the initial position of the pipes is fixed.

[0044] Step-by-step sliding control: Start the feeding cylinder 17, which will extend and retract according to the preset program or control signal, driving the sorting baffle 18 to rotate around the hinge point. The limit bracket 181 on the top of the sorting baffle 18 changes its position accordingly, thereby controlling the pipe to slide along the top of the guide shaft rail 14 in a step-by-step manner. When the limit bracket 181 is released to a certain extent, the pipe slides forward a short distance along the guide shaft rail 14 under the action of gravity; when the limit bracket 181 blocks again, the pipe stops sliding, and the cycle continues, ensuring that the pipe slides smoothly along the guide rail to the silo.

[0045] Stable entry into the silo: When the pipe slides along the guide shaft rail 14 to the position of the loading beam 22, the loading beam 22 and related components provide stable support for the pipe to prevent the pipe from shaking or tipping over, allowing the pipe to further enter the silo formed by the column 1, the support beam 2 and the material blocking column 4.

[0046] Position adjustment in the silo: Through the coordinated adjustment of the feeding cylinder 17 and other related cylinders, the stacking position of the pipes in the silo is accurately controlled according to the actual situation of the pipes, so that the pipes stay stably in the silo. For example, by adjusting the angle and position of the sorting baffle 18, the pipes are arranged neatly and at a suitable height and horizontal position.

[0047] Prevent excessive accumulation: During the pipe accumulation process, when the predetermined number is reached, the lifting cylinder 19 is activated. The top output end of the lifting cylinder 19 drives the material blocking assembly 20 to move, and the pipe is appropriately lifted in the vertical direction to prevent the subsequent pipes from continuing to accumulate excessively on the same plane, ensuring that the pipe accumulation in the silo is always in a reasonable state.

[0048] Uniform stacking and pushing: Control the pushing cylinder 201 to start, the pushing shock-absorbing block 202 at the end of the pushing cylinder 201 buffers the impact force during pushing, and the pushing block 203 applies thrust to the pipes to evenly stack the pipes inside the silo, so that the distribution of the pipes in the silo is more uniform and reasonable, which is convenient for subsequent packaging operations.

[0049] Packaging Operation

[0050] The motor 7 is started, and the output shaft of the motor 7 drives the rotating shaft 9 to rotate through the sprocket transmission group 8, thereby driving the coaxially connected material belt reel 10 to rotate. During the rotation of the material belt reel 10, the strapping belt 5 wound around the top of the column 1 and the material belt reel 10 is guided by the guide wheel 11 to pack the pipes accumulated in the silo. The blocking plate 6 set on the strapping belt 5 ensures that the strapping belt 5 is in an accurate position during movement and work, avoiding deviation and other situations that affect the packaging effect.

[0051] Process monitoring and assurance

[0052] During the entire pipe feeding and packaging process, the first swing arm limit switch 15 and the second swing arm limit switch 16 on the diagonal support frame 13 monitor the position and movement state of the pipe in real time. When the pipe touches the limit switch, a corresponding signal will be generated and fed back to the control system. The control system determines the feeding status of the pipe based on these signals, such as whether it has reached the specified position, whether abnormal sliding occurs, etc., and adjusts the working status of the feeding cylinder 17, the lifting cylinder 19, the pushing cylinder 201 and the motor 7 accordingly to ensure the accurate execution of various actions, ensure that the entire device can operate stably and efficiently, and realize the function of fully automatic pipe feeding and packaging.

[0053] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
