Description

Technical Field

[0001] This invention relates to the field of crude oil (gas) storage tank technology, and in particular to a device and method for applying adhesive tape to the prefabricated and reserved ends of tank plates. Background Technology

[0002] With the continuous development of the petroleum industry, the storage capacity of oil products is constantly increasing, and more and more crude oil (gas) storage tanks are being used. The number of newly built tank farms is increasing, but in the field of tank corrosion protection, the level of mechanization and automation in construction is not high. With the successful application of automated prefabrication production lines for tank plate corrosion protection, the corresponding supporting equipment needs to improve its automation level to ensure consistent production rhythm. During tank plate prefabrication corrosion protection, to ensure welding quality and reduce damage to the anti-corrosion coating from welding, a 5cm gap needs to be left around the steel plate without anti-corrosion spraying. The traditional method is to manually apply tape to the gap, a task that requires two people to operate after shot blasting and sandblasting of the steel plate. However, manual tape application is arbitrary and cannot guarantee the tightness and regularity of the tape application. Manual tape application not only restricts production progress and increases manpower input, but also poses significant safety hazards during the operation. Summary of the Invention

[0003] The purpose of this invention is to provide a device and method for applying tape to the pre-fabricated reserved ends of tank plates, so as to solve the problems of slow production speed, high personnel input and safety hazards when applying tape manually.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0005] A device for applying tape to pre-fabricated tank plates includes a short-side tape application device and a long-side tape application device. The first direction is perpendicular to the tank plate's forward movement, and the second direction is the same as the forward movement of the tank plate. The short-side tape application device includes an upper tape application mechanism and a lower tape application mechanism, both movable along the second direction. The upper and lower tape application mechanisms have identical structures and are symmetrically arranged. The upper tape application mechanism applies tape to the side of the tank plate along the first direction, and the lower tape application mechanism applies tape to the lower side of the tank plate along the first direction. The long-side tape application device applies tape to the side of the tank plate along the second direction.

[0006] Furthermore, the tape application mechanism includes a tape reel, a cutting component, and a pressing component; the tape reel is used to store tape, the cutting component is used to cut tape, and the pressing component is used to clamp tape and move it in a first direction to drive the tape out of the tape reel and arrange it in the first direction.

[0007] Furthermore, the tape pressing assembly includes tape claws, two of which can move toward each other to engage with each other, thereby clamping the tape.

[0008] Furthermore, the adhesive application assembly also includes a gripper mounting plate and a movable plate; the adhesive tape gripper is mounted on the gripper mounting plate, the gripper mounting plate is hinged to the movable plate, and the movable plate can move in a first direction; the gripper mounting plate swings around the hinge point to drive the adhesive tape gripper to swing, thereby causing the adhesive tape to move toward the can plate and adhere to the can plate.

[0009] Furthermore, the adhesive pressing assembly also includes a first telescopic rod and a second telescopic rod; the first telescopic rod is mounted on the pneumatic gripper mounting plate and connected to the tape gripper, and is used to drive the tape gripper to move to bite the tape; one end of the second telescopic rod is hinged to the pneumatic gripper mounting plate and the other end is hinged to the moving plate, and is used to push the pneumatic gripper mounting plate to swing.

[0010] Furthermore, the sticker application mechanism also includes a brush mounted on a movable plate, which moves along a first direction under the drive of the movable plate to press the tape firmly onto the can plate.

[0011] Furthermore, the cutting assembly includes a cutter and a cutting pressure plate, the cutting pressure plate being movable in a direction perpendicular to the can plate to compress the tape, and the cutter being movable in a direction perpendicular to the can plate to cut the tape.

[0012] Furthermore, the cutting assembly also includes a cutting tray, which is located on the side of the tape away from the cutter. The cutting tray has a cutting groove into which the cutter can be inserted to cut the tape.

[0013] Furthermore, the long-side tape applicator includes a tape machine and a cutting assembly; the tape machine includes a tape roll and a limiting wheel, the tape roll is used to store the tape and output the tape in a second direction, the tape is located between the limiting wheel and the can plate after being output from the tape roll, the limiting wheel applies pressure to the can plate to stick the tape to the can plate; the cutting assembly includes a cutter for cutting the tape.

[0014] In another aspect, the present invention provides a method for applying adhesive tape to the pre-fabricated reserved ends of tank plates, using the aforementioned adhesive tape application equipment for pre-fabricated reserved ends of tank plates, comprising the following steps:

[0015] Lateral tape application: The pressing assembly pulls the tape from the tape reel laterally to the required length. After the can plate moves to the tape application position in the second direction, the short side tape application device moves synchronously with the can plate. During the synchronous movement, the pressing assembly presses the tape onto the can plate, and then the cutting assembly cuts the tape.

[0016] Longitudinal tape application: After the tank plate is moved to the tape application position, the tape machine presses down to stick the tape to the tank plate. As the tank plate moves, the tape is pulled out from the tape machine and stuck to the tank plate. After the tape is pasted, the cutting component cuts the tape.

[0017] In summary, the technical effects achieved by this invention are as follows:

[0018] The prefabricated can plate tape application device provided by this invention includes a short-side tape application device and a long-side tape application device; the direction perpendicular to the can plate's forward movement is designated as the first direction, and the forward movement direction of the can plate is designated as the second direction; the short-side tape application device includes an upper tape application mechanism and a lower tape application mechanism, which can move along the second direction; the upper and lower tape application mechanisms have the same structure and are symmetrically arranged, the upper tape application mechanism is used to apply tape to the side of the can plate along the first direction, and the lower tape application mechanism is used to apply tape to the lower side of the can plate along the first direction; the long-side tape application device is used to apply tape to the side of the can plate along the second direction.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] When prefabricating tank plates for corrosion protection, to ensure welding quality and reduce damage to the anti-corrosion coating during welding, a 5cm gap must be left around the perimeter of the steel plate without anti-corrosion spraying. Traditionally, this is done by manually applying tape to this gap, a task requiring two people after shot blasting of the steel plate. However, manual tape application is inconsistent and cannot guarantee tightness or regularity. It not only hinders production progress and increases manpower input but also poses significant safety hazards during the process.

[0035] In view of this, the present invention provides a device for applying tape to the pre-fabricated reserved end of a tank plate, comprising a short-side tape application device 10 and a long-side tape application device 20; the direction perpendicular to the forward movement of the tank plate is designated as the first direction, and the forward movement of the tank plate is designated as the second direction; the short-side tape application device 10 includes an upper tape application mechanism 100 and a lower tape application mechanism 200, which are movable along the second direction; the upper tape application mechanism 100 and the lower tape application mechanism 200 have the same structure and are symmetrically arranged, the upper tape application mechanism 100 is used to apply tape to the side of the tank plate along the first direction, and the lower tape application mechanism 200 is used to apply tape to the lower side of the tank plate along the first direction; the long-side tape application device 20 is used to apply tape to the side of the tank plate along the second direction.

[0036] The prefabricated tank plate tape application equipment provided by the present invention uses the short side tape application device 10 and the long side tape application device 20 to work together to complete the tape application work during the movement of the tank plate without stopping the movement of the tank plate. This reduces labor intensity, effectively improves production speed, requires only one person to operate and can realize automated work, thus improving safety.

[0037] The following combination Figures 1-9 The structure and shape of the tank plate prefabrication and pre-reserved end tape application equipment provided in this embodiment are described in detail:

[0038] In an optional embodiment, the short-side tape applicator 10 includes an upper tape applicator 100, a lower tape applicator 200, and a short-side frame 300. The upper tape applicator 100 and the lower tape applicator 200 are mounted on the short-side frame 300, which can reciprocate along a second direction, such as... Figure 1 , Figure 2 , Figure 3 As shown.

[0039] Since the upper sticker mechanism 100 and the lower sticker mechanism 200 are structurally symmetrical, the upper sticker mechanism 100 will be used as an example, combined with... Figure 5 , Figure 6 Structural description follows. Specifically, the sticker application mechanism 100 includes a tape reel 110, a cutting assembly 120, a pressing assembly 130, and a brush 140. The tape reel 110 is used to store tape, and its axis is parallel to the second direction.

[0040] The cutting assembly 120 includes a cutter 121, a cutting pressure plate 122, a cutting tray 123, a tape tray 124, a tape guide plate 125, a cutting cylinder 126, a pressure plate cylinder 127, and a tray cylinder 128. For example... Figure 5As shown, the tape support plate 124 is located on the side of the tape closest to the steel plate, supporting the tape and preventing it from sagging and being gripped by the tape pressing assembly 130. The surface of the tape support plate 124 in contact with the tape has grooves extending in a second direction to reduce the contact area and prevent the tape from sticking to the tape support plate 124. The tape guide plate 125 is located on the side of the tape away from the tape support plate 124 and below the tape reel 110, changing the direction of the tape output from the tape reel 110, causing it to extend laterally, i.e., along the first direction. The cutter 121 is connected to the extended end of the cutting cylinder 126, and the cutting pressure plate 122 is connected to the extended end of the pressure plate cylinder 127. Both the cutter 121 and the cutting pressure plate 122 are located on the side of the tape away from the steel plate. The cutting support plate 123 is located below the cutter 121 and on the side of the tape away from the cutter 121.

[0041] Specifically, after the tape is output from the tape roll 411, it enters between the tape tray 124 and the tape guide plate 125. After being turned by the tape guide plate 125, it extends along the first direction. After the tape is pasted, the pressure plate cylinder 127 extends and drives the cutting pressure plate 122 to press the tape onto the steel plate, ensuring the pasting effect while assisting the cutter 121 in cutting. Subsequently, the cutting cylinder 126 extends and drives the cutter 121 to move downward to cut the tape. The cutting tray 123 is used to hold the tape so that the cutter 121 can cut it. Furthermore, the cutting tray 123 is provided with a cutting groove extending along the second direction. When the cutter 121 cuts the tape, it is inserted into the cutting groove to ensure that the tape is cut. At the same time, by providing the cutting groove, the contact area between the cutting tray 123 and the tape can be reduced, preventing the tape from sticking to the cutting tray 123.

[0042] In this embodiment, to ensure the cutting effect, the contact point between the cutter 121 and the tape is set in a serrated shape to facilitate cutting the tape. To ensure the cutting effect and prevent adhesion, a blade can be added. The blade is connected to the cutting cylinder 126, i.e., it moves synchronously with the cutter 121. The blade's cutting edge is angled, ensuring that it cuts at the edge of the tape when in contact with it, ensuring that the tape can be torn. By setting the blade, it avoids the serrations of the cutter 121 leaving only holes in the tape without damaging the edge, which would prevent the tape from breaking smoothly after cutting. The edge cut ensures that the tape can be torn apart under its own tension.

[0043] To facilitate the operation of the adhesive tape pressing assembly 130, and to enable the adhesive tape pressing assembly 130 to grip the cut end of the tape and pull the tape out of the tape reel 110, such as... Figure 6 As shown, the pallet cylinder 128 is connected to the cutting pallet 123 and is used to drive the cutting pallet 123 to move in the second direction so that the cutting pallet 123 is detached from the tape.

[0044] The adhesive application assembly 130 includes tape grippers 131, a pneumatic gripper mounting plate 132, a moving plate 133, a first telescopic rod 134, a second telescopic rod 135, a transverse motor 136, and a transverse gear 137. Specifically, two tape grippers 131 are mounted on the pneumatic gripper mounting plate 132, and the two tape grippers 131 are located on the upper and lower sides of the tape. The tape is gripped by the engagement of the two tape grippers 131. The pneumatic gripper mounting plate 132 is hinged to the moving plate 133. One end of the second telescopic rod 135 is hinged to the pneumatic gripper mounting plate 132, and the other end is hinged to the moving plate 133. The first telescopic rod 134 is mounted on the pneumatic gripper mounting plate 132 and connected to the tape grippers 131, and is used to drive the tape grippers 131 to move and engage the tape. Specifically, the first telescopic rod 134 can be connected to one of the tape grippers 131, and is used to drive this tape gripper 131 to move in the vertical direction.

[0045] The structure of tape claw 131 is as follows Figure 9 As shown, the surface of the tape claw 131 that contacts the tape is provided with an elongated groove perpendicular to the first direction, which forms teeth to facilitate the interlocking of the tape claws 131.

[0046] In this embodiment, the first telescopic rod 134 and the second telescopic rod 135 can be pneumatic cylinders or electric cylinders.

[0047] A transverse motor 136 is mounted on the movable plate 133, and a transverse gear 137 is connected to the output end of the transverse motor 136. The movable plate 133 is movably connected to the short side frame 300. The transverse motor 136 drives the transverse gear 137 to rotate, and the transverse gear 137 engages with the rack 330 on the short side frame 300, thereby causing the adhesive pressing assembly 130 to move along the first direction.

[0048] The brush 140 is connected to the pneumatic gripper mounting plate 132 and is used to smooth the pasted tape.

[0049] To ensure tape tension and facilitate smooth application, a damping device is installed on the tape reel 110. A friction block can be placed against the tape reel 110, or a mechanical or pneumatic clamp can be used to hold the flange of the tape reel 110, in which case the tape reel 110 has an I-beam structure. The mechanism of the damping device is a common structure and will not be described in detail here.

[0050] The working process of sticker application mechanism 100 is as follows:

[0051] The first telescopic rod 134 extends, opening the two tape claws 131. At the same time, the transverse motor 136 drives the transverse gear 137, causing the tape pressing assembly 130 to move towards the tape support plate 124. After moving into position, the end of the suspended tape is located between the two tape claws 131. At this time, the first telescopic rod 134 retracts, and the tape claws 131 clamp the tape.

[0052] At this time, the transverse motor 136 rotates in the opposite direction to move the pressing assembly 130 away from the tape support plate 124. Simultaneously, the tape claw 131 pulls the tape, causing the tape to be continuously output from the tape roll 411 until the pressing assembly 130 moves to the desired position. When the can arrives, the second telescopic rod 135 extends, causing the pneumatic gripper mounting plate 132 to swing, which in turn drives the tape claw 131 to swing, bringing the tape closer to the can and sticking it to the can. At this time, the pressure plate cylinder 127 extends to drive the cutting pressure plate 122, further ensuring the adhesion between the tape and the can.

[0053] After the tape is pasted, the tray cylinder 128 extends, moving the cutting tray 123 below the cutter 121. The cutting cylinder 126 extends and cooperates with the cutting tray 123 to cut the tape. After cutting, the tray cylinder 128 retracts to detach the cutting tray 123 from the tape. Simultaneously, the first telescopic rod 134 extends, causing the tape claw 131 to open and release the tape. The traverse motor 136 starts, causing the pressing assembly 130 to move towards the tape tray 124 so that the tape claw 131 can grip the tape again. During the movement, the brush 140 brushes the tape already pasted on the can plate to ensure reliable and flat pasting.

[0054] The lower sticker mechanism 200 works in the same way as the upper sticker mechanism 100; the two can work simultaneously or at different times.

[0055] In this embodiment, the short-side frame 300 includes a frame body 310 and rollers 320, racks 330, linear units 340, power components 350, and upper support components 360 mounted on the frame body 310. Tape reel 110 and cutting components 120 are mounted on the frame body 310, and the adhesive pressing component 130 is mounted on the frame body 310 via linear guide rails. Specifically, a moving plate 133 is connected to a slider, and the guide rails are mounted on the frame body 310, with the linear guide rails arranged along a first direction.

[0056] like Figure 1 As shown, rack 330 is mounted on frame 310 and engages with transverse gear 137 to move adhesive application assembly 130. Idler roller 320 is mounted on frame 310 to support the can plate, preventing it from bending due to suspension and affecting tape adhesion. Upper support assembly 360 is mounted on frame 310 to lift the tape upwards, assisting lower tape application mechanism 200 in application; the number of upper support assemblies 360 can be adjusted according to the width of the can plate.

[0057] Specifically, such as Figure 8As shown, the upper support assembly 360 includes a sponge pad 361, an upper support cylinder 362, a connector 363, and a connecting frame 364. The connecting frame 364 is mounted on the frame body 310 and connected to the upper support cylinder 362. One side of the connector 363 is connected to the extended end of the upper support cylinder 362, and the other side is connected to the sponge pad 361. The connector 363 can be supported using an aluminum profile. During operation, when the lower sticker mechanism 200 applies the tape to the underside of the can plate, the upper support cylinder 362 extends, causing the sponge pad 361 to lift the tape, pressing it firmly onto the can plate to ensure adhesion and prevent the tape from failing to adhere to the can plate due to insufficient tension and gravity.

[0058] The linear unit 340 and the power assembly 350 cooperate to drive the frame body 310 to move in a second direction. The linear unit 340 can be a combination of a linear guide rail and a rack 330. The linear guide rail is connected to the ground, the slider is connected to the frame body 310, and the rack 330 is used to transmit power. The power assembly 350, as shown... Figure 7 As shown, it includes a motor, coupling, and gears. To achieve power transmission, a drive shaft extending along a first direction is also provided to transmit the power provided by the power assembly 350. Gears are connected to both ends of the drive shaft to engage with the rack 330 on the linear unit 340. That is, the gears in the power assembly 350 drive the drive shaft to rotate, and the drive shaft transmits power to the linear unit 340 to achieve the movement of the frame 310, thereby realizing the synchronous movement of the upper sticker mechanism 100 and the lower sticker structure with the can plate.

[0059] The working process of the short-side tape applicator 10 is as follows:

[0060] As the can plate moves along the conveyor line, the pressure-adhesive assembly 130 in the upper and lower adhesive applicator 200 pre-extracts the tape to the required length. When the sensor detects the arrival of the can plate, the short-side frame drives the upper adhesive applicator 100 and the lower adhesive applicator 200 to move synchronously with the can plate. Subsequently, the second telescopic rod 135 and the pressure plate cylinder 127 extend to adhere the tape to the can plate, while the upper support cylinder 362 extends to ensure that the lower tape is adhered to the can plate. Finally, the cutting assembly 120 cuts the tape, and the brush 140 moves towards the tape support plate 124 under the drive of the pressure-adhesive assembly 130, allowing the brush 140 to brush over the tape adhered to the can plate, improving the adhesion quality. During this process, the short-side tape applicator 10 maintains synchronous movement with the can plate to remain relatively stationary, ensuring adhesion quality and increasing adhesion speed.

[0061] In an optional embodiment, the long-side tape applicator 20 includes a tape machine 410, a cutting assembly 420, a first telescopic cylinder 430, a mounting plate 440, and a mounting beam 450. For example... Figure 1 , Figure 4The mounting beam 450 extends along a first direction. A mounting plate 440 is connected to the mounting beam 450. The cutting assembly 420 is connected to the conveyor belt 410. One end of the first telescopic cylinder 430 is hinged to the conveyor belt, and the other end is hinged to the mounting plate 440. The mounting plate 440 has elongated holes along the first direction to facilitate adjustment of its position, thereby accommodating tank plates of different widths. Figure 1 As shown, the long-side tape applicator 20 includes two tape dispensers 410, a cutting assembly 420, a first telescopic cylinder 430, and a mounting plate 440 to achieve the application of two tapes along a second direction.

[0062] Specifically, the tape machine 410 includes a tape roll 411, a limiting wheel 412, and a connecting plate 413. The tape roll 411 and the limiting wheel 412 are disposed between two connecting plates 413. A first telescopic rod 134 is hinged to the connecting plate 413, and the connecting plate 413 is hinged to the mounting plate 440. The cutting assembly 420 includes a cutter 421 and a cutting telescopic cylinder 422. The cutter 421 is connected to the extended end of the cutting telescopic cylinder 422 and is used to cut the tape after application.

[0063] The working process of the long-side tape applicator 20 is as follows:

[0064] After the tape is output from the tape roll 411, it hangs down to the limit wheel 412 and is located on the side of the limit wheel 412 close to the mounting plate 440.

[0065] When the can plate moves to the pasting position, the first telescopic cylinder 430 extends, causing the tape machine 410 and the cutting assembly 420 to swing toward the can plate. At this time, the end of the can plate pushes the tape to move below the limiting wheel 412. The limiting wheel 412 applies pressure to the can plate, causing the tape to stick to the can plate. As the can plate moves, the tape is driven by the can plate and output from the tape roll 411. After pasting is completed, the cutting telescopic rod extends and the cutter 421 cuts the tape to complete the pasting.

[0066] To achieve automated pasting, appropriate sensors need to be set up to confirm the position of the can plate. At the same time, a controller is used to match the moving speed of the short side frame 300 with that of the can plate, and a servo motor can be used to ensure the accuracy of synchronization.

[0067] In another aspect, the present invention provides a method for applying adhesive tape to the pre-fabricated reserved ends of tank plates, using the aforementioned adhesive tape application equipment for pre-fabricated reserved ends of tank plates, comprising the following steps:

[0068] Lateral tape application: The pressing assembly 130 pulls the tape from the tape reel 110 laterally to the required length. After the can plate moves to the tape application position in the second direction, the short side tape application device 10 moves synchronously with the can plate. During the synchronous movement, the pressing assembly 130 presses the tape onto the can plate, and then the cutting assembly 120 cuts the tape.

[0069] Longitudinal tape application: After the tank plate is moved to the tape application position, the tape machine 410 presses down to stick the tape to the tank plate. As the tank plate moves, the tape is pulled out from the tape machine 410 and stuck to the tank plate. After the tape is stuck, the cutting component 420 cuts the tape.

[0070] When applying the tape, first complete the application of the first horizontal strip of tape, then apply the vertical strip of tape, and then apply the second horizontal strip of tape while the vertical strip of tape is being applied.

[0071] The prefabricated tank plate tape application equipment provided in this embodiment can accurately detect the position and speed of the tank plate, ensuring the accuracy of tape application and ensuring that the tape is properly adhered to the edge of the steel plate within 5cm, thus avoiding the need for anti-corrosion spraying.

[0072] For thinner floating plates, such as 5mm thick plates, the ends tend to sag after sandblasting and rust removal. The idler rollers 320 can support these plates, ensuring they remain level and thus guaranteeing bonding quality. In other words, by installing idler rollers 320, the gap in the conveyor roller track is shortened, preventing large gaps in the tank plates.

[0073] This equipment can be designed using a modular programming approach, which facilitates various combinations and modifications of equipment functions, as well as future maintenance and functional improvements. It features database maintenance capabilities, allowing for timely adjustment and maintenance of ports and communication lines based on actual production conditions. Furthermore, the equipment has networking capabilities, enabling it to connect to existing production networks and provide necessary production data to subsequent processes, thus achieving data sharing.

[0074] Conventional manual tape application requires two people to stretch the tape to the correct position and stick it to the steel plate surface. This process carries the risk of the steel plate being squeezed or collided with the tape. In automated mechanical operations, personnel operate the equipment from outside the work line, completely eliminating these safety risks.

[0075] The tape-applying equipment for prefabricated tank plate prefabrication and reserved ends provided in this embodiment ensures that each anti-corrosion process is closely linked, transforming manual operations into assembly line operations. This not only reduces manpower input and improves construction efficiency but also greatly reduces safety risks. Taking the production of tank wall plates as an example, the spraying time for a single steel plate is 3.6 minutes, while the manual tape application time is at least 2 minutes. After using this equipment, manual operation time is saved, and the steel plate can be directly sprayed after shot blasting and rust removal, increasing construction efficiency by 55%.

[0076] The tank plate prefabrication and pre-reserved end tape application equipment provided in this embodiment does not require stopping the tank plate conveying, ensuring production continuity. The tape is tightly applied and accurately positioned. It also has the advantages of high automation, high production speed, low personnel input, and high safety.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
