[0002] PPR pipe is a kind of polymer material pipe, and it is also the replacement product of UPVC water supply pipe, aluminum-plastic pipe, PE pipe, PE-X pipe and PE-RT pipe. Because it uses random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed, thus becoming the main force of water pipe materials. It is widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. In recent years, with the continuous increase in market demand in the construction, municipal engineering, water conservancy engineering, agriculture and industry, China's PPR pipe industry has shown a rapid development trend, and the corresponding PPR three-way joints have also developed rapidly.

[0003] At present, after the production of PPR three-way joints, in order to display the product information to customers through labels and meet the anti-counterfeiting needs, the pipes need to be manually labeled. After the labeling operation is completed, in order to better protect the products, facilitate storage and promote sales during the circulation process such as product transportation, storage and sales, the PPR three-way joints need to be manually packaged. The existing manual labeling and manual packaging operations have the following disadvantages: 1. During the manual labeling operation, manual labeling often leads to uneven label positions on the surfaces of different PPR three-way joints, and is also easy to cause contamination on the surface of paper labels, and the anti-counterfeiting effect of paper labels is general; 2. During the manual labeling operation, manual labeling often leads to uneven label positions on the surfaces of different PPR three-way joints, and is also easy to cause contamination on the surface of paper labels, and the anti-counterfeiting effect of paper labels is general; 3. During the manual labeling operation, manual labeling often leads to uneven label positions on the surfaces of different PPR three-way joints, and is also easy to cause contamination on the surface of paper labels, and the anti-counterfeiting effect of paper labels is general; 4. During the manual labeling operation, manual labeling often leads to uneven label positions on the surfaces of different PPR three-way joints, and is also easy to cause contamination on the surface of paper labels, and the anti-counterfeiting effect of paper labels is general; 5. During the manual labeling operation, manual labeling often leads to uneven label positions on the surfaces of different PPR three-way joints, and is also easy to cause contamination on the surface of paper labels, and the anti-counterfeiting effect of paper labels is general; 6. During the manual labeling operation, manual labeling often leads to uneven label positions on the surfaces of different PPR three-way joints, and is also easy to cause contamination on the surface of paper labels, and the anti-counterfeiting effect of paper labels is general; 7. During the manual labeling operation, manual labeling often leads to uneven label positions on the surfaces of During the packaging process, because the PPR tee joints have both copper-plated and non-copper-plated parts, and the number of PPR tee joints contained in different packaging specifications is different, manual packaging is slow, the labor intensity of employees is high, and it is very easy for workers to make mistakes in the number of PPR tee joints they load into each product. Therefore, the existing manual labeling and manual packaging operations are time-consuming, labor-intensive and inefficient, so it is urgently needed to improve the mechanization level of the coding and packaging operations of the PPR tee joints through research and development. However, due to the special shape of the PPR tee joint, there is currently no device on the market that can be used to improve the mechanization level of the coding and packaging operations of the PPR tee joints. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems in the existing technology and propose a semi-automatic coding and packaging mechanism for PPR three-way joints. The technical problem solved by the present invention is to realize detection and coding, counting and sorting, and automatic packaging while completing the guided transportation of PPR three-way joints, and it can be applied to PPR three-way joints of different specifications.

[0005] The objective of the present invention can be achieved through the following technical solutions: a semi-automatic coding and packaging mechanism for a PPR three-way joint, comprising a frame, characterized in that a conveying mechanism is arranged on the frame, the conveying mechanism comprises a conveyor belt device and a guide conveying device arranged adjacently, the guide conveying device comprises two mounting plate racks which are symmetrically arranged and can approach or move away from each other, and the two mounting plate racks can synchronously approach or move away from the frame, and the two mounting plate racks are rotatably provided with synchronous pulley assemblies, the transmission surfaces of the two synchronous pulley assemblies are parallel and relatively arranged so that a guide transportation channel which can be used to clamp and convey the PPR three-way joint so that it can pass upright is formed between the two transmission surfaces, a photoelectric sensor 1 for detecting the PPR three-way joint is arranged below the guide transportation channel, a coding device which can automatically code according to the detection result of the photoelectric sensor 1 is arranged on the side of the guide conveying device, the guide conveying device is connected to an automatic packaging machine, and a sorting device for counting and sorting the coded PPR three-way joints is arranged between the guide conveying device and the automatic packaging machine.

[0006] When in use, the operator first arranges the PPR pipes on the conveyor belt device of the conveying mechanism, and the transmission surfaces of the two synchronous pulley assemblies of the semi-automatic coding and packaging mechanism of the PPR three-way joint are parallel and relatively arranged so that a guide transportation channel that can be used to clamp and convey the PPR three-way joint to pass upright is formed between the two transmission surfaces. The PPR three-way joints enter the guide transportation channel one by one through the conveyor belt (the operator can adjust the distance between the two mounting plate racks and the distance between the two mounting plate racks and the frame, so that the width and height of the guide transportation channel formed by the transmission surfaces of the two synchronous pulley assemblies change, so that the guide transportation channel can adapt to the passage of PPR three-way joints of different specifications). The photoelectric sensor located below the guide transportation channel can detect and sense the PPR three-way joint passing through the guide transportation channel. When the photoelectric sensor detects the PPR When the three-way joint is being transported, the coding device located beside the guiding conveying device can automatically code according to the detection result of the photoelectric sensor 1, so as to realize accurate coding (that is, the coding device will perform coding operation only when the photoelectric sensor 1 detects that the PPR three-way joint has entered the coding area of ​​the coding device). The coded PPR three-way joint enters the sorting device, and the sorting device counts and sorts the coded PPR three-way joint according to the preset single-piece packaging quantity. The coded PPR three-way joint counted and sorted by the sorting device enters the automatic packaging machine, and the automatic packaging machine automatically packages a certain number of PPR three-way joints, thereby realizing detection and coding, counting and sorting as well as automatic packaging while completing the guided conveying of the PPR three-way joint, and can be applied to PPR three-way joints of different specifications, which greatly improves the mechanization level and work efficiency of coding and packaging of PPR three-way joints.

[0007] In the above-mentioned semi-automatic coding and packaging mechanism for PPR three-way joints, both mounting plate racks are provided with abutment plates for supporting the bottom of the PPR three-way joint, and there is a gap between the two abutment plates for a photoelectric sensor to detect the PPR three-way joint in the guide transport channel.

[0008] The two abutment plates can support the bottom of the PPR three-way joint, which can prevent the PPR three-way joint from falling from the guide transportation channel to the ground, thereby improving the reliability of the guide transportation channel formed between the two transmission surfaces for clamping and conveying the PPR three-way joint. At the same time, there is a gap between the two abutment plates for the photoelectric sensor to detect the PPR three-way joint in the guide transportation channel, so that the setting of the two abutment plates will not block the detection of the PPR three-way joint in the guide transportation channel by the photoelectric sensor, thereby realizing detection, coding, counting, sorting and automatic packaging while completing the guided transportation of the PPR three-way joint, and can be suitable for PPR three-way joints of different specifications, which greatly improves the mechanization level and work efficiency of coding and packaging of the PPR three-way joint.

[0009] In the above-mentioned semi-automatic coding and packaging mechanism of a PPR three-way joint, a movable limiting device is also provided on the two mounting plate frames, and the movable limiting device includes two limiting rods arranged opposite to each other, and the distance between the two limiting rods is less than the width of the guide transport channel. At least one adjusting component is provided between the limiting rod and the mounting plate frame, and the adjusting component includes a transverse adjusting screw rod respectively arranged on the two limiting rods, a connecting block rod is provided on the transverse adjusting screw rod, a vertical adjusting screw rod is passed through the connecting block rod, and the vertical adjusting screw rod is connected to the mounting plate frame.

[0010] The movable limit device can limit the PPR three-way joint in the guide transport channel to prevent the PPR three-way joint from jumping out from the top. At the same time, the distance and height between the two limit rods are adjustable, so that the movable limit device can be suitable for PPR three-way joints of different specifications, thereby improving the reliability of the guide transport channel formed between the two transmission surfaces for the clamping and conveying of the PPR three-way joint, thereby realizing detection, coding, counting, sorting and automatic packaging while completing the guided conveying of the PPR three-way joint, and can be suitable for PPR three-way joints of different specifications, which greatly improves the mechanization level and work efficiency of PPR three-way joint coding and packaging.

[0011] In the above-mentioned semi-automatic coding and packaging mechanism for a PPR three-way joint, the conveyor belt device includes a conveyor belt arranged on a frame and a sorting guide assembly arranged on the conveyor belt, the sorting guide assembly includes two guide rods arranged opposite to each other, and a guide channel for a single PPR three-way joint to pass through is formed between the two guide rods. At least one adjustment assembly 2 is arranged between the guide rods and the frame, and the adjustment assembly 2 includes two transverse adjustment screws respectively arranged on the two guide rods, and two connecting blocks are arranged on the two transverse adjustment screws. Two vertical adjustment screws are passed through the two connecting blocks, and the two vertical adjustment screws are connected to the frame.

[0012] The sorting guide assembly on the conveyor device can pre-sort the PPR three-way joints and wait for the next process. The operator can sort the PPR three-way joints on the conveyor device so that the PPR three-way joints on the conveyor device are placed upright and enter the guide transportation channel one by one through the conveyor belt. At the same time, the distance and height between the two guide rods are adjustable, so that the sorting guide assembly can be suitable for PPR three-way joints of different specifications, thereby realizing detection and coding, counting and sorting, and automatic packaging while completing the guided transportation of the PPR three-way joints, and can be suitable for PPR three-way joints of different specifications, which greatly improves the mechanization level and work efficiency of PPR three-way joint coding and packaging.

[0013] In the above-mentioned PPR three-way joint semi-automatic coding and packaging mechanism, material temporary storage grooves and side guards are respectively arranged on both sides of the frame, and the material temporary storage grooves and side guards are respectively arranged adjacent to the two guide rods. A loading elevator is arranged on one side of the end of the frame, and the loading elevator is arranged adjacent to the material temporary storage groove. A feeding hopper is arranged at the bottom of the loading elevator, and a clearance gap is arranged on the feeding hopper for the material truck to enter. A foot switch for manually controlling the start and stop of the loading elevator is arranged below the frame.

[0014] When the PPR three-way joint semi-automatic coding and packaging mechanism is in use, the operator first pushes the material cart equipped with the PPR three-way joint to the feeding elevator, and then places the PPR three-way joint in the material cart on the feeding elevator. The elevator can be freely controlled according to the number of placed PPR three-way joints, that is, the PPR three-way joint on the elevator is continuously transported to the conveyor belt to replace manual handling. The feed hopper can temporarily store the PPR three-way joint, which is convenient for the operator to place the PPR three-way joint in the material cart on the feeding elevator. According to the use requirements, the feeding elevator can also be started and stopped by a manual foot switch; the PPR three-way joint transported by the feeding elevator first enters the material temporary storage tank, and then the operator temporarily controls the material. The PPR three-way joint in the storage tank is manually placed on the conveyor belt. The temporary material storage tank can expand the operating surface of the conveyor belt and improve the work efficiency of the operator. The side guard can prevent the PPR three-way joint on the conveyor belt from falling to the ground. At the same time, the temporary material storage tank and the side guard are respectively arranged adjacent to the two guide rods, which can guide the PPR three-way joint of the conveyor belt to pass through the guide channel formed between the two guide rods in sequence, and prevent the PPR three-way joint on the conveyor belt from falling to the ground from the side, thereby realizing the detection and coding, counting and sorting as well as automatic packaging while completing the guided transportation of the PPR three-way joint, and it can be applied to PPR three-way joints of different specifications, which greatly improves the mechanization level and work efficiency of PPR three-way joint coding and packaging.

[0015] In the above-mentioned semi-automatic coding and packaging mechanism for a PPR three-way joint, the sorting device includes a mounting frame and two photoelectric sensors for counting, a sorting funnel and a cylinder are arranged on the mounting frame, a sorting baffle which can close or open the sorting funnel is arranged at the bottom of the sorting funnel, and the sorting baffle is transmission-connected to the cylinder.

[0016] Firstly, the number of PPR three-way joints dropped from the sorting hopper to the packaging elevator is counted by counting the photoelectric sensor 2. When the number reaches the preset value, the cylinder on the mounting frame controls the sorting baffle to close the sorting funnel, so that the PPR three-way joint in the sorting funnel no longer drops to the packaging elevator, until the previously dropped PPR three-way joint is packaged by the automatic packaging machine, the cylinder on the mounting frame controls the sorting baffle to open the sorting funnel, so that the number of PPR three-way joints packaged by the automatic packaging machine in a single time can be adjusted and controlled to meet the packaging requirements of different quantities, thereby improving the versatility of the semi-automatic coding and packaging mechanism of the PPR three-way joint.

[0017] In the above-mentioned semi-automatic coding and packaging mechanism for a PPR three-way joint, the sorting device also includes a visual detection component for detecting and identifying defective products, and the side of the sorting funnel is provided with a side channel connected to its main channel and inclined downward, and the side of the sorting funnel opposite to the side channel is provided with a funnel flap that can be used to close the main channel and open the side channel, and the side of the sorting device is provided with a material box for receiving defective products coming out of the side channel.

[0018] The visual inspection component can adopt the method of taking pictures with an industrial camera. The sorting device of the above structure can detect defective products and remove them in time before packaging the PPR three-way joint. Specifically, when the visual inspection component detects defective products, the funnel flap flips to close the main channel and open the side channel, so that the defective products enter the material box along the side channel until the visual inspection component detects that the product meets the standards. The funnel flap returns to its original position, and the main channel of the sorting funnel continues to open, and the cycle is repeated in sequence, thereby ensuring the quality of the packaged PPR three-way joint.

[0019] In the above-mentioned PPR three-way joint semi-automatic coding and packaging mechanism, a packaging elevator is arranged between the sorting device and the automatic packaging machine, a PLC electric control box is arranged next to the packaging elevator, the conveyor belt device, packaging elevator, photoelectric sensor 1, coding device, photoelectric sensor 2, sorting device and automatic packaging machine are electrically connected to the PLC electric control box respectively, the automatic packaging machine is connected to a weighing device, and the weighing device is electrically connected to the PLC electric control box.

[0020] The PLC electric control box can complete the automatic control of the conveyor belt device, packaging elevator, photoelectric sensor 1, coding device, photoelectric sensor 2, sorting device and automatic packaging machine, as well as the linkage between the devices; the weighing device can be an electronic scale, and weighing the packaged PPR three-way joint can verify whether the packaging quantity is accurate and ensure the packaging quality.

[0021] In the above-mentioned PPR three-way joint semi-automatic coding and packaging mechanism, a transverse screw adjustment assembly for adjusting the distance between the two mounting plate frames is arranged below the two mounting plate frames, and a longitudinal screw adjustment assembly for adjusting its height is arranged on the transverse screw adjustment assembly. The guide conveying device also includes a motor, and the motor is respectively connected to the two synchronous pulley assemblies through an adjustable transmission assembly.

[0022] The transverse screw adjustment assembly and the longitudinal screw adjustment assembly facilitate the adjustment of the width and height of the guide transport channel formed by the transmission surfaces of the two synchronous belt pulley assemblies. Specifically, the width of the guide transport channel can be changed by adjusting the transverse screw adjustment assembly (after the operator adjusts the transverse screw adjustment assembly, the two mounting plates will move, and the two synchronous belt pulley assemblies correspondingly arranged on the two mounting plates will also move as the position of the mounting plates changes, thereby changing the width of the guide transport channel formed by the transmission surfaces of the two synchronous belt pulley assemblies), and the height of the guide transport channel can be changed by adjusting the longitudinal screw adjustment assembly (the operator adjusts the transverse screw adjustment assembly After the component is moved, the height of the transverse screw rod adjustment assembly will change, and the height of the two mounting plates connected to the transverse screw rod adjustment assembly will also change accordingly. The two synchronous belt pulley assemblies correspondingly arranged on the two mounting plates will also change with the change in the height of the mounting plates, thereby changing the height of the guide transport channel formed by the transmission surfaces of the two synchronous belt pulley assemblies), so that the guide transport channel can adapt to the passage of PPR three-way joints of different specifications, and the motor is respectively connected to the two synchronous belt pulley assemblies through an adjustable transmission assembly, so that the guide transport channel can drive the PPR three-way joint to move forward after clamping the PPR three-way joint, thereby realizing the clamping and transportation of the PPR three-way joint. In the above-mentioned PPR three-way joint semi-automatic coding and packaging mechanism, the transmission assembly includes a driving wheel shaft 1 and a driving wheel shaft 2 respectively arranged on the driving wheels of the two synchronous pulley assemblies, and a rotating secondary shaft and a mounting rod respectively arranged on two mounting plate frames, a tensioning adjustment wheel is rotatably arranged on the mounting rod, the rotating secondary shaft is located on the side of the driving wheel shaft 1, and the mounting rod is located on the side of the driving wheel shaft 2, the driving wheel shaft 1 and the transmission shaft of the motor are connected by belt transmission, and the driving wheel shaft 1 and the rotating secondary shaft are driven by gear meshing, the rotating secondary shaft, the driving wheel shaft 2 and the tensioning adjustment wheel are connected by belt transmission, the mounting plate frame is provided with an adjustment hole for the movement of the mounting rod along the length direction, and the mounting rod is arranged on the mounting plate frame through an adjusting screw.

[0023] The motor drives the driving wheel shaft 1 to rotate through the belt transmission, and the driving wheel shaft 1 drives the rotating secondary shaft to rotate through the gear transmission, and the rotating secondary shaft drives the driving wheel shaft 2 and the tensioning adjustment wheel to rotate through the belt transmission. When the width of the guide transport channel changes, the transmission belt between the rotating secondary shaft, the driving wheel shaft 2 and the tensioning adjustment wheel cannot be tensioned, and it is necessary to adjust the position of the mounting rod in the adjustment hole to re-tighten the transmission belt between the rotating secondary shaft, the driving wheel shaft 2 and the tensioning adjustment wheel. Therefore, the transmission component of the above structure can adapt to the transmission requirements when the width of the guide transport channel changes, thereby realizing the detection and coding, counting and sorting and automatic packaging of the PPR three-way joint while completing the guided transportation of the PPR three-way joint, and can be suitable for PPR three-way joints of different specifications, which greatly improves the mechanization level and work efficiency of the coding and packaging of the PPR three-way joint.

[0024] Compared with the prior art, the advantages of the semi-automatic coding and packaging mechanism for PPR three-way joints are: the semi-automatic coding and packaging mechanism for PPR three-way joints can realize detection and coding, counting and sorting as well as automatic packaging while completing the guided transportation of PPR three-way joints, and can be applied to PPR three-way joints of different specifications, which greatly improves the mechanization level and work efficiency of coding and packaging of PPR three-way joints, and can also improve the quality of coding and packaging of PPR three-way joints.
