Description

Technical Field

[0001] This invention belongs to the technical field of traffic safety facility production equipment, and in particular relates to a system and control method for automatically applying reflective tape to warning posts. Background Technology

[0002] Warning posts are traffic safety facilities, devices used to indicate and remind pedestrians and vehicles to pay attention to traffic safety. They are usually made of materials such as plastic, rubber, and metal, and have eye-catching colors and reflective materials to attract the attention of pedestrians and vehicles and remind them to pay attention to traffic safety. They are usually set up in places such as roads, bridges, tunnels, and parking lots, especially in accident-prone areas and road maintenance and construction sites, to remind drivers and pedestrians to pay attention to safety.

[0003] After production, warning posts typically require reflective tape to be applied to their surface to make them eye-catching and reflective. However, the application of reflective tape to warning posts is usually done manually, and the tape is then cut by hand. This is inefficient, labor-intensive, and the manual cutting can result in uneven cuts, affecting the appearance of the warning post.

[0004] For example, Chinese patent application number (CN201910500133.8) discloses an automatic device for applying warning tape to cylindrical warning posts, including a base, a conveyor, a frame plate, a guardrail plate, a grooved wheel, a first motor, a cam, a first cylindrical block, a second motor, a first turntable, and a V-shaped swing arm. The frame plate is installed on the top of the base, and openings are opened on both the left and right sides of the frame plate. Conveyors for conveying warning posts are installed on both the left and right sides of the top of the base. This application reduces labor intensity and improves safety by automatically applying warning tape to the warning posts. However, this application does not limit the radial and axial direction of the warning posts when applying warning tape, which can easily cause the warning tape to shift in the axial direction of the warning post. At the same time, the lack of radial limitation can easily lead to bulges or wrinkles in the warning tape, affecting the adhesion and aesthetics. Summary of the Invention

[0071] S12: Repeat S3-S12.

[0072] The beneficial effects of this invention are as follows:

[0073] 1. Before applying reflective tape, limit the warning post in the radial and axial directions to ensure that the height of the reflective tape is uniform and to prevent the reflective tape on the surface of the warning post from bulging or wrinkling, thereby improving the appearance of the warning post.

[0074] 2. The warning post is radially limited by the frustum portion, and the first and second sub-clamps are connected by elastic elements. After the second sub-clamp abuts against the warning post, it can continue to push the first sub-clamp, so that the first push rod abuts against the inner walls at both ends of the warning post under the action of the second push rod. On the one hand, it improves the fixing effect of the warning post and avoids slippage between the warning post and the second sub-clamp when applying reflective tape, which would affect the adhesion effect. On the other hand, the first push rod can further promote the radial limitation, so that the warning post is less likely to cause radial deviation during rotation.

[0075] 3. The setting of the stop levers facilitates the control of the position of the second sub-clamp plate. In conjunction with the third drive component, the two stop levers enable the relative position of the warning post and the reflective tape to be effectively adjusted. This facilitates the control of the adhesion height of the reflective tape on the warning post, adapting to different models of warning posts and improving the accuracy of the adhesion height.

[0087] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0088] Example 1:

[0089] This embodiment provides a system for automatically applying reflective tape to warning posts, including:

[0090] Rack 1;

[0091] The adhesive application mechanism 2 is used to automatically apply reflective tape to the warning posts and is installed inside the frame 1;

[0092] The conveying mechanism 3 is used for feeding the warning posts and conveying them after the reflective tape is pasted. It is installed inside the frame 1 and located below the tape-applying mechanism 2.

[0093] Radial limiting mechanism 4 is used to limit the warning post radially and is installed inside the adhesive applicator 2;

[0094] The axial limiting mechanism 5 is used to limit the axial movement of the warning column and is installed inside the frame 1.

[0095] As can be seen from this embodiment, before applying reflective tape, the warning post is limited in the radial and axial directions to ensure that the height of the reflective tape is uniform and to prevent the reflective tape on the surface of the warning post from bulging or wrinkling, thus improving the aesthetics of the warning post.

[0096] Example 2:

[0097] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the tape-applying mechanism 2 includes:

[0098] Tape feeding assembly 20 is used for feeding reflective tape;

[0099] Cutting assembly 21 is used for cutting reflective tape;

[0100] The clamping and rotating assembly 22 is used for rotating the warning post after clamping it and for attaching reflective tape.

[0101] As can be seen from this embodiment, the reflective tape is fed by the tape feeding component 20, and after the reflective tape is pasted, it is cut by the cutter component 21 to ensure the flatness of the cut and the aesthetics. The warning post is driven to rotate by the clamping and rotating component 22. In conjunction with the tape feeding component 20, reflective stickers are automatically and continuously pasted on multiple warning posts. The work efficiency is high, time and labor are saved, and labor intensity is effectively reduced.

[0102] Example 3:

[0103] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the clamping and rotating assembly 22 includes:

[0104] Clamping plates 220 are slidably installed in the frame 1, and there are two of them, which are used to clamp the two ends of the warning post respectively;

[0105] The first driving component 221 is installed on the top wall inside the frame 1 and is used to drive the two clamping plates 220 to move upward along the warning column axis.

[0106] Connecting plates 222 are installed inside the frame 1, and there are two of them. One end is installed at the output end of the first drive unit 221, and the other end is connected to the bearings of the two clamping plates 220 respectively.

[0107] The second driving component 223 is mounted on the connecting plate 222 and is used to drive the clamping plate 220 to rotate.

[0108] The first driving component 221 can be driven by a motor 513 to drive the lead screw, or it can be pushed by a cylinder. A slider rail structure is provided between the connecting plate 222 and the top wall inside the frame 1 to improve the stability of the connecting plate 222 when it slides.

[0109] The second driving component 223 can be a servo motor 513, and the two connecting plates 222 located at both ends of the warning post only need to be driven by a servo motor 513 on one side, while the other side is installed and connected by setting a bearing seat.

[0110] As can be seen from this embodiment, the first driving member 221 drives the connecting plate 222 to move, and the bearing connection between the clamping plate 220 and the connecting plate 222 ensures that the second driving member 223 installed on the connecting plate 222 drives the clamping plate 220 to rotate, thereby driving the rotation of the warning post, which facilitates the application of reflective tape to the warning post.

[0111] Example 4:

[0112] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the radial limiting mechanism 4 includes:

[0113] The frustum portion 40 is mounted on the axis of the clamping plate 220 near the warning post and is used for radial positioning of the warning post.

[0114] As can be seen from this embodiment, by setting a frustum portion 40 at the center of the axis near the warning post on the side of the clamping plate 220, a radial limiting function can be achieved when the clamping plate 220 clamps the warning post.

[0115] Example 5:

[0116] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions of the above embodiments, it also has the following technical features:

[0117] The clamping plate 220 includes a first sub-clamping plate 220a and a second sub-clamping plate 220b, and the connecting plate 222 includes a first sub-connecting plate 222a and a second sub-connecting plate 222b. One end of the first sub-connecting plate 222a is connected to the first sub-clamping plate 220a by a bearing, and the other end is slidably connected to the top wall inside the frame 1. One end of the second sub-connecting plate 222b is connected to the second sub-clamping plate 220b by a bearing, and the other end is slidably connected to the top wall inside the frame 1.

[0118] The radial limiting mechanism 4 also includes:

[0119] The cylinder 41 is installed on the side of the frustum 40 near the warning post and is coaxial with the frustum 40, and has multiple grooves 46 on its surface circumference.

[0120] The push rod 42 has one end connected to the axis of the first sub-clamp plate 220a, and the other end passes through the second sub-clamp plate 220b and is slidably connected to the cylinder 41.

[0121] The first push rod 43 has one end hinged to the push rod 42, and the other end extends through the slide groove 46 to the surface of the cylinder 41.

[0122] The second push rod 44 is hinged at one end to the end of the cylinder 41 away from the frustum 40, and at the other end to the first push rod 43.

[0123] Elastic element 45 is installed between the first sub-clamp plate 220a and the second sub-clamp plate 220b;

[0124] The second sub-clamp plate 220b is located on the side of the first sub-clamp plate 220a near the warning post, and the frustum portion 40 is mounted on the second sub-clamp plate 220b, while the second driving member 223 is mounted on the first sub-connecting plate 222a.

[0125] Meanwhile, the elastic element 45 can be a spring 64, which is sleeved on the push rod 42.

[0126] As can be seen from this embodiment, the first sub-clamping plate 220a and the second sub-clamping plate 220b connected by the elastic member 45 allow the second sub-clamping plate 220b to continue pushing the first sub-clamping plate 220a after it abuts against the warning post. This causes the first push rod 43 to abut against the inner walls at both ends of the warning post under the action of the second push rod 44. On the one hand, this improves the fixing effect of the warning post and prevents slippage between the warning post and the second sub-clamping plate 220b when applying reflective tape, which would affect the application effect. On the other hand, the first push rod 43 can further promote radial limitation, making it less likely for the warning post to deviate radially during rotation.

[0127] Furthermore, the end of the first push rod 43 furthest from the push rod 42 is also provided with a friction-enhancing component 6, which is used to increase the frictional resistance between the first push rod 43 and the inner wall of the warning post, and the friction-enhancing component 6 includes:

[0128] The mounting platform 60 is connected to the first top rod 43 and has a countersunk hole 67, and a through hole 68 is provided on the bottom wall of the countersunk hole 67.

[0129] Guide rod 61 is installed in through hole 68 and is slidably connected to the inner wall of through hole 68;

[0130] The slide rod 62 is installed in the countersunk hole 67 and is slidably connected to the inner wall of the countersunk hole 67, and is integral with the guide rod 61.

[0131] The top block 63 is installed on the sliding column 512 and is integrated with the sliding rod 62 and the guide rod 61.

[0132] Spring 64 is installed in countersunk hole 67 and sleeved on the surface of guide rod 61, with its two ends abutting against slide rod 62 and bottom wall of countersunk hole 67 respectively;

[0133] The elastic block 65 is installed on the top block 63 and bonded to the top block 63. It is preferably made of rubber to further increase the frictional resistance between the first top post and the inner wall of the warning post and prevent slippage.

[0134] Pressure sensor 66 is mounted on mounting platform 60 and located below top block 63, and is used to detect the pressure of top block 63 on mounting platform 60;

[0135] In the above scheme, by judging the force exerted by the first push rod 43 on the inner wall of the warning column, it can serve as a trigger switch to stop the first drive component 221. On the other hand, the force exerted by the first push rod 43 on the inner wall of the warning column can be judged by the values ​​of the pressure sensors 66 on multiple first push rods 43. This allows us to understand whether multiple forces are the same or have little difference, thereby judging the effect of radial limiting of the warning column, which is convenient for equipment maintenance or repair.

[0136] Example 6:

[0137] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the axial limiting mechanism 5 includes:

[0138] The stop bar 50 is slidably connected to the frame 1, and there are two of them, which are used to limit the axial movement of the two second sub-clamp plates 220b respectively;

[0139] The third drive unit 51 is mounted on the frame 1 and is used to drive the two stop levers 50 to slide along the axial direction of the warning post.

[0140] The third driving component 51 includes:

[0141] The drive rod 510 is mounted on the frame 1, and both ends are provided with bearing seats, and threaded grooves 511 are opened on the surface;

[0142] The sliding column 512 is connected at one end to the stop bar 50 and at the other end to be adapted to the groove 511 and extend into the groove 511;

[0143] Motor 513 is mounted on frame 1 and is used to drive the rotation of drive rod 510;

[0144] Meanwhile, a slider rail structure is provided at the connection between the top of the stop lever 50 and the slide column 512 to connect with the frame 1, thereby improving the stability and accuracy of the stop lever 50 during adjustment, and the motor 513 can be a servo motor 513.

[0145] As can be seen from this embodiment, the setting of the stop levers facilitates the control of the position of the second sub-clamp plate 220b. In conjunction with the third drive component 51, the two stop levers enable the relative position of the warning post and the reflective tape to be effectively adjusted. This facilitates the control of the adhesive height of the reflective tape on the warning post, adapting to different models of warning posts (the adhesive height and position of the reflective tape on different models of warning posts of the same height may vary due to design and usage environment factors). Furthermore, it facilitates the control of the adhesive height, further improving the accuracy of the adhesive position of the reflective tape.

[0146] Example 7:

[0147] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the tape feeding assembly 20 includes:

[0148] The first support 200 is slidably mounted on the frame 1 and is equipped with a smooth guide roller 201, a sticking guide roller 202 and a pressure roller 203;

[0149] The tape output rack 204 is mounted on the first bracket 200 and is used to install reflective tape;

[0150] The fourth driving component 205 is mounted on the frame 1 and is used to drive the first support 200 to slide.

[0151] Brush 206 is mounted on the first bracket 200 and is used for cleaning the surface of the warning post before the reflective tape is applied.

[0152] The first cylinder 207 is mounted on the first bracket 200 and is used to simultaneously move the adhesive guide roller 202 and the pressure roller 203 closer to or further away from the warning post.

[0153] The second cylinder 208 is mounted on the first bracket 200 and is used to move the brush 206 closer to or further away from the warning post.

[0154] The fourth driving component 205 can be driven by a motor 513 to drive the lead screw, and the first bracket 200 and the frame 1 are also connected by a slider rail structure. The tape output frame 204 is a frame for supporting reflective tape and the reflective tape can rotate. It is existing technology and will not be described in detail here.

[0155] Meanwhile, the smooth guide roller 201 is used to contact the non-adhesive side of the reflective tape and changes the conveying angle of the reflective tape. The adhesive guide roller 202 is used to contact the adhesive side of the reflective tape and changes the conveying angle of the reflective tape. At the same time, the surface of the guide roller will not stick to the reflective tape. The pressure roller 203 is used to contact the non-adhesive side of the reflective tape and to press the reflective tape against the surface of the warning post to ensure that the reflective tape adheres to the warning post. The materials of the smooth guide roller 201, the adhesive guide roller 202, and the pressure roller 203 are all existing technologies. The specific selection should be based on achieving the above functions, which will not be elaborated here.

[0156] As can be seen from this embodiment, the cooperation of the smooth guide roller 201, the adhesive guide roller 202, and the pressure roller 203 facilitates the guidance of reflective tape to the surface of the warning post. As the warning post rotates, the reflective tape is adhered to the surface of the warning post. The brush 206 facilitates the cleaning of the surface of the warning post before the reflective tape is applied, preventing surface stains from affecting the adhesion between the reflective tape and the surface of the warning post. The use of the first cylinder 207 and the second cylinder 208 facilitates the adjustment and activation of the brush 206 and the pressure roller 203, i.e., cleaning before applying adhesive, resulting in good automation and high efficiency.

[0157] Example 8:

[0158] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the cutter assembly 21 includes:

[0159] The second bracket 210 is installed inside the frame 1;

[0160] The cutter 211 is mounted on the second bracket 210 via a cutter 211 holder and is used for cutting reflective tape.

[0161] The third cylinder 212 is mounted on the second bracket 210 and is used to move the cutter 211 closer to or further away from the warning post.

[0162] The fifth driving component 213 is mounted on the second bracket 210 and is used to drive the cutter 211 frame to slide along the surface of the warning post;

[0163] Among them, the fifth driving component 213 can be a motor 513 driving a lead screw, and the cutter 211 can be a roller cutter, while the third cylinder 212 can be a dual-axis cylinder to improve the stability of the movement of the cutter 211 frame, thereby improving the stability of the cutter 211 in cutting reflective tape.

[0164] As can be seen in this embodiment, the third cylinder 212 pushes the cutter 211 to abut against the reflective tape and penetrate it. Then, the fifth drive component 213 drives the cutter 211 to roll, cutting the reflective tape. The cut is flat, improving the aesthetics. Moreover, the use of a rolling cutter structure makes it less likely to pull the reflective tape compared to a straight cutter, preventing the pasted reflective tape from being torn apart, ensuring the pasting effect of the reflective tape and reducing the defect rate.

[0165] Example 9:

[0166] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the conveying mechanism 3 includes:

[0167] Feed conveyor 30 is used for feeding the warning posts;

[0168] The discharge conveyor 31 is used for conveying the warning posts after the reflective tape has been applied.

[0169] The feeding rack 32 is installed below the frame 1, and has multiple feeding claws 33 at equal intervals around its circumference for clamping the warning column;

[0170] The sixth driving component 34 is installed on the side of the loading rack 32 and is used to drive the loading rack 32 to rotate;

[0171] The feeding rack 35 is installed between the feeding conveyor 30 and the loading rack 32, and its surface is inclined to the side of the loading rack 32.

[0172] The baffle 36 is installed on the feeding rack 35 and is used for single feeding of the warning column. It is equipped with a fourth cylinder 37 to drive the baffle 36 to rise and fall.

[0173] The loading rack 32 includes a material picking station, an adhesive application station, and a material discharging station; and the loading claw 33 can be used to hold the cylinder and a clamping claw can be set at the output end of the cylinder. In order to avoid the influence of the rotating loading rack 32 on the clamping cylinder, a rotary air pipe connector can be used. These are all existing mature technologies, which will not be elaborated here.

[0174] As can be seen from this embodiment, the material feeding station, adhesive application station and discharge station are set on the feeding rack 32. The feeding and discharging are carried out automatically by the feeding conveyor 30 and the discharging conveyor 31, which is highly efficient, requires less manual intervention and has low cost. The inclined feeding rack 35 facilitates automatic feeding. At the same time, the fourth cylinder 37 drives the baffle 36 to rise and fall, which facilitates automatic individual feeding and ensures the effective and orderly progress of the process.

[0175] Example 10:

[0176] This embodiment provides a system for automatically applying reflective tape to warning posts. In addition to the technical solutions described in the above embodiments, it also has the following technical features. The control method of the above system includes:

[0177] S1: Device starts;

[0178] S2: The warning posts are conveyed, and the positions of the two baffles 50 are adjusted according to the model of the warning posts being processed and the position of the reflective tape.

[0179] S3: Drive the baffle 36 to descend, and after a single warning post rolls into the feeding claw 33, the baffle 36 rises;

[0180] S4: Clamp the warning post, drive the first bracket 200 away, the feeding rack 32 rotates, and move the warning post to the adhesive application station;

[0181] S5: Release the warning post, push the first sub-clamp 220a, and the second sub-clamp 220b will be pushed along with the first sub-clamp 220a;

[0182] S6: The second sub-clamp plate 220b abuts against the warning post and pushes the warning post to move axially until the second sub-clamp plate 220b touches the stop bar 50 and stops.

[0183] S7: Continue pushing the first sub-clamp plate 220a, the elastic element 45 is compressed, and at the same time the push rod 42 is pushed out of the cylinder 41, causing the first push rod 43 and the second push rod 44 to rotate until the first push rod 43 abuts against the inner wall of the warning post.

[0184] S8: Drive the first bracket 200 to approach, drive the brush 206 to abut against the surface of the warning post, and drive the warning post to rotate until the surface of the warning post is cleaned.

[0185] S9: After the drive brush 206 moves away from the warning post, the drive pressure roller and tape come into contact with the surface of the warning post, and at the same time drive the warning post to rotate, sticking the reflective tape until the sticking is completed;

[0186] S10: Drive the cutter 211 to abut against the warning post and penetrate the reflective tape. Then drive the cutter 211 to move and cut the reflective tape until the cutting is completed. Then drive the second cylinder 208 and the third cylinder 212 to reset.

[0187] S11: Clamp the warning post, drive the loading rack 32 to rotate, transport the warning post to the discharge station, and then release the warning post to complete the automatic application of reflective tape to a single warning post;

[0188] S12: Repeat S3-S12.

[0189] As can be seen from this embodiment, the above control method makes it more convenient to automatically apply reflective tape to the warning post. By adjusting the positions of the two stop bars 50, the position of the second sub-clamp plate 220b can be limited, which plays a role in axial limitation. After the second sub-clamp plate 220b abuts against the warning post, the first sub-clamp plate 220a is pushed further, which will squeeze the elastic element 45, thereby causing the push rod 42 to be pushed out, causing the first push rod 43 to abut against the inner wall of the warning post. This not only plays a role in radial limitation, but also increases the abutment strength of the second sub-clamp plate 220b against the warning post. This makes it easier for the second drive member 223 to rotate the warning post, improves the connection strength, and prevents the warning post from slipping during rotation. This effectively avoids the reflective tape from bulging or wrinkling on the warning surface.
