Description

Technical Field

[0001] The invention relates to the technical field of coating substrate stacking, and in particular to a loading and unloading device for coating substrates. Background Art

[0002] Coating substrates are key raw materials in the coating process. There are many types of coating substrates, including paper, plastic film, metal, etc. Coating substrates are widely used in various industries, such as bonding and release industries (adhesive tapes, protective films, etc.) and functionalization industries (optical films, lithium batteries, etc.). In the coating process, they often appear in roll form to facilitate continuous coating operations.

[0003] The transfer and loading and unloading of coated substrates in the warehouse is an important part of supply chain optimization. It is to improve production efficiency and logistics efficiency, reduce waiting time and manual intervention, optimize inventory management and resource utilization, reduce costs, improve safety and management level, ensure that raw materials arrive at the designated location on time and in quantity, support variable production needs, and ultimately improve customer satisfaction. Through an efficient transfer and loading and unloading system, the entire supply chain can be optimized to ensure smooth production. When transporting substrates, it is usually necessary to rely on automated equipment and procedures to achieve the transfer and removal of coated substrates. However, due to the characteristics of the coated substrates themselves, such as irregular placement, it is difficult to ensure the accuracy of loading and unloading during transportation. In addition, automated equipment may also have certain deviation errors during the handling process. These factors together increase the difficulty of operation.

[0004] Based on the above situation, the present invention proposes a loading and unloading device for coating substrates. Summary of the invention

[0005] In order to overcome the disadvantages that due to the characteristics of the coated substrate itself, such as irregular placement, it is difficult to ensure the accuracy of loading and unloading during transportation. In addition, the automated equipment may also have certain deviation errors during the transportation process. These factors together increase the difficulty of operation. The present invention proposes a loading and unloading device for a coated substrate.

[0007] Furthermore, it also includes mounting columns. The second and third sections of the rod are provided with mounting columns on one side close to the first section of the rod. The first and second sections of the rod are provided with mounting holes on one side close to the third section of the rod. The mounting columns rotate in the adjacent mounting holes.

[0008] Furthermore, it also includes a reinforcement mechanism for resisting the top and bottom sides of the inner wall of the reel to increase stability. The reinforcement mechanism is arranged on the second slider, and the reinforcement mechanism includes a fixed rod, which is fixed to the side of the second slider away from the second connecting rod. The first connecting rod and the fixed rod are both slidably connected with a guide frame, and a first spring is connected between the guide frame and the first connecting rod and the fixed rod. The first spring is respectively wound on the first connecting rod and the fixed rod, and the first section of the plug rod and the second section of the plug rod are both slidably connected with symmetrically distributed brackets.

[0009] Furthermore, each guide frame is provided with evenly distributed convex columns, each clamping frame is provided with symmetrically distributed oblique sliding grooves, and the convex columns slide in adjacent oblique sliding grooves.

[0010] Furthermore, it also includes a locking mechanism that prevents the insertion rod from shaking when the substrate roll is lifted from the shelf. The locking mechanism is arranged in each mounting column. The locking mechanism includes a pressure block, which is slidably connected to each mounting column. Each mounting column is slidably connected with symmetrically distributed L-shaped blocks. A second spring is connected between the L-shaped block and the adjacent mounting column, and a retaining ring is fixed in each mounting hole.

[0011] Furthermore, the pressing block is squeezed and matched with the adjacent L-shaped clamping block.

[0012] Furthermore, it also includes an anti-skid mechanism for increasing the contact area between the insertion rod and the substrate roll to prevent it from slipping. The anti-skid mechanism is arranged on the third section of the insertion rod. The anti-skid mechanism includes a rotating frame, which is rotatably connected to the side of the third section of the insertion rod away from the second section of the insertion rod, and a gear is fixedly connected to the side of the rotating frame close to the fixed rod. A torsion spring is connected between the rotating frame and the third section of the insertion rod, and the torsion spring is wound on the rotating frame. A telescopic rod is fixedly connected to the side of the rotating frame away from the third section of the insertion rod, and a sliding rod is slidably connected to the side of the third section of the insertion rod close to the telescopic rod, and a rack is fixedly connected to the bottom of the sliding rod.

[0013] Furthermore, the rack meshes with the gear.

[0014] Furthermore, it also includes a control mechanism for determining whether the telescopic rod is used. The control mechanism is arranged on the third section of the plug rod. The control mechanism includes a gear shift. The gear shift is slidably connected to the side of the third section of the plug rod close to the telescopic rod. The side of the third section of the plug rod close to the telescopic rod is rotatably connected with a screw, and the screw is threadedly connected to the gear shift.

[0016] The present invention has the following advantages: the present invention first designs the insertion rod to be three sections that are rotatably connected, so that when the substrate and the transfer equipment are not completely aligned, they can still be smoothly inserted, and there is no need to frequently adjust the positions of the substrate and the equipment, thus saving time and labor, and improving operational flexibility and work efficiency. The three sections of the insertion rod are then stretched into a whole by the first slider and the second slider, ensuring the stability and safety of the substrate during the transfer process, reducing accidents caused by position deviation, and even if the initial position deviates, it will automatically stretch and lock after insertion, ensuring the stability of the substrate during the transfer process, thereby improving the stacking efficiency.

[0017] The present invention, through the cooperation between the guide frame and the clamping frame, can not only clamp the roll from the inside during the process of straightening the insertion rod, thereby improving the stability and safety of the substrate during transportation, ensuring that the substrate can be stacked at the designated position smoothly and accurately, thereby improving the efficiency and reliability of the entire transportation process, but also can automatically adjust according to the different inner diameters of the roll, so that the insertion rod can adapt to rolls of various sizes, thereby improving the versatility of the equipment.

[0018] The present invention can straighten the substrate roll after it is pulled out through the cooperation of the pressing block, the L-shaped clamping block and the clamping ring, thereby ensuring that the substrate is more stable during transportation and will not shake due to the swing of the fork rod, thereby reducing the risk during transportation. This design simplifies the operating steps and does not require additional adjustments, so that operators can complete the stacking task more quickly and easily.

[0019] The present invention first ensures the stability and safety of the coated substrate during the lifting process through the cooperation of the sliding rod, rack, gear, telescopic rod, etc., thereby improving the stacking efficiency, and then through the cooperation of the gear shift and the screw, it is convenient to control whether the telescopic rod is used, thereby improving the flexibility of the device operation.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0031] Embodiment 1: A loading and unloading device for coating a substrate, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a transfer vehicle 1, which is slidably connected to a connecting frame 2 on the upper left side of the transfer vehicle 1, a first section of the plug rod 3 is fixedly connected to the left side of the connecting frame 2, the first section of the plug rod 3 is rotatably connected to the left side of the second section of the plug rod 31, the second section of the plug rod 31 is rotatably connected to the left side of the third section of the plug rod 32, an electric push rod 4 is installed in the connecting frame 2, the telescopic part on the left side of the electric push rod 4 is fixedly connected to the first connecting rod 5, the first slider 6 is rotatably connected to the left side of the first connecting rod 5, the second connecting rod 51 is rotatably connected to the left side of the first slider 6, the second connecting rod 51 is rotatably connected to the second slider 61, the second slider 61 slides in the second section of the plug rod 31 and the third section of the plug rod 32, and the first slider 6 slides in the first section of the plug rod 3 and the second section of the plug rod 31.

[0032] like Figure 3 As shown, it also includes a mounting column 33. The second section rod 31 and the third section rod 32 are each provided with a mounting column 33 on the upper right side. The first section rod 3 and the second section rod 31 are each provided with a mounting hole 34 on the upper left side. The mounting column 33 rotates in the adjacent mounting hole 34.

[0033] When using the device, first control the transfer vehicle 1 to approach the shelf where the coated substrate roll is placed, and the third section insertion rod 32 is facing left and aligned with one of the roll openings, and continue to control the transfer vehicle 1 to move toward the coated substrate. At this time, the third section insertion rod 32, the second section insertion rod 31 and the first section insertion rod 3 will be inserted into the roll in sequence. If the coated substrate itself is not placed neatly on the shelf, that is, the roll as a whole and the insertion rods are not in a straight line, at this time, as the third section insertion rod 32, the second section insertion rod 31 and the first section insertion rod 3 move into the roll, the inner wall of the roll will resist the third section insertion rod 32, causing it and the second section insertion rod 31 to deflect slightly, and will drive the second connecting rod 51, the first slider 6, and the second slider 61 to deflect together.

[0034] After the third section of the insertion rod 32, the second section of the insertion rod 31 and the first section of the insertion rod 3 are completely inserted into the roll, the transfer vehicle 1 is first controlled to drive the connecting frame 2 to move upward, thereby lifting the coated substrate roll from the shelf through the third section of the insertion rod 32, the second section of the insertion rod 31 and the first section of the insertion rod 3, and then the transfer vehicle 1 is controlled to move to the right, thereby driving the coated substrate roll to withdraw from the shelf through the insertion rod. At this time, the electric push rod 4 can be controlled to drive the first connecting rod 5 to move to the right, thereby driving the first slider 6 and the second slider 61 to move to the right. The first slider 6 and the second slider 61 moving to the right will be respectively located at the connection between the insertion rods, thereby making the first section of the insertion rod 3, the second section of the insertion rod 31, and the third section of the insertion rod 32 straightened into a whole, making the three insertion rods in a stiff state, and the insertion rods straightened into a whole have improved load-bearing capacity.

[0035] Continue to control the transfer vehicle 1 to move towards the destination. According to the previous steps, the insertion rod that lifts the coated substrate roll is moved into another shelf, and the connecting frame 2 is controlled to move downward to place the coated substrate roll on the horizontal plate of the shelf, and then the transfer vehicle 1 is controlled to move away from this shelf, so that the insertion rod is withdrawn from the roll, and finally the electric push rod 4 is controlled to drive the first connecting rod 5 to move to the left and reset, thereby driving the first slider 6 and the second slider 61 to move to the left and reset. In summary, the insertion rod is first designed to be three sections connected in rotation, so that when the substrate and the transfer equipment are not completely aligned, it can still be smoothly inserted, and there is no need to frequently adjust the position of the substrate and the equipment, which saves time and labor, and improves the flexibility and work efficiency of operation. Then, the three-section insertion rod is straightened into a whole through the first slider 6 and the second slider 61, ensuring the stability and safety of the substrate during transportation, reducing accidents caused by position deviation, and even if the initial position deviates, it will automatically straighten and lock after insertion, ensuring the stability of the substrate during transportation, thereby improving the stacking efficiency.

[0036] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 5 As shown, it also includes a reinforcement mechanism for resisting the top and bottom sides of the inner wall of the reel to increase stability. The reinforcement mechanism is arranged on the second slider 61, and the reinforcement mechanism includes a fixed rod 7, which is fixedly connected to the left side of the second slider 61. The first connecting rod 5 and the fixed rod 7 are both slidably connected with a guide frame 8. The two guide frames 8 and the first connecting rod 5 and the fixed rod 7 are each connected with a first spring 9. The two first springs 9 are respectively wound around the first connecting rod 5 and the fixed rod 7. The top and bottom walls of the first section plug rod 3 and the second section plug rod 31 are both slidably connected with a bracket 10. There are four brackets 10. The front and rear sides of the two guide frames 8 are symmetrically provided with bosses. The front and rear sides of the four brackets 10 are each provided with an inclined slide groove, and the bosses slide in the adjacent inclined slide grooves. The top and bottom walls of the first section plug rod 3 and the third section plug rod 32 are each provided with five through holes, and the bracket 10 slides in the adjacent through holes.

[0037] When the electric push rod 4 drives the first connecting rod 5 to move to the right, the guide frame 8 also moves to the right, thereby driving the clamping frame 10 to move outward until it contacts the inner wall of the roll. The clamping frame 10 moving outward will clamp the inner wall of the roll from the top and bottom sides, thereby increasing the stability of the coated substrate rolled on the insertion rod. At this time, the inner wall of the roll will resist the clamping frame 10, thereby resisting the guide frame 8, forming a stable supporting structure. As the electric push rod 4 drives the first connecting rod 5 to continue to move to the right, the fixed rod 7 and the first connecting rod 5 will continue to move right relative to the guide frame 8, causing the first spring 9 to deform.

[0038] When the electric push rod 4 drives the first connecting rod 5 to move to the left and reset, and under the elastic action of the first spring 9, the guide frame 8 will move to the left and reset, and the clamping frame 10 will move inward and reset at the same time. In summary, through the cooperation between the guide frame 8 and the clamping frame 10, not only can the reel be clamped from the inside during the straightening of the insertion rod, thereby improving the stability and safety of the substrate during transportation, ensuring that the substrate can be stacked smoothly and accurately at the designated position, improving the efficiency and reliability of the entire transportation process, but also can automatically adjust according to the inner diameter of the different reels, so that the insertion rod can adapt to reels of various sizes, thereby improving the versatility of the equipment.

[0039] like Figure 6 and Figure 7 As shown, it also includes a locking mechanism that prevents the insertion rod from shaking when the substrate roll is lifted from the shelf. The locking mechanism is arranged in the two mounting columns 33. The locking mechanism includes a pressure block 11. The pressure block 11 is slidably connected to the upper part of the two mounting columns 33 respectively. The lower part of the two mounting columns 33 is slidably connected with symmetrically distributed L-shaped blocks 12. A second spring 13 is connected between the L-shaped block 12 and the adjacent mounting column 33. A retaining ring 14 is fixed in the two mounting holes 34.

[0040] When the transfer vehicle 1 drives the connecting frame 2 to move upward, that is, when the third section rod 32, the second section rod 31, and the first section rod 3 lift the coated substrate roll from the shelf, the inner wall of the roll will press against the pressure block 11 to move it downward, thereby squeezing the L-shaped block 12 to move it outward until it contacts the retaining ring 14, the second spring 13 will deform, and friction will be generated between the retaining ring 14 and the L-shaped block 12, so that the mounting column 33 and the mounting hole 34 are in closer contact, and then when the inner wall of the roll presses against the third section rod 32 and causes it to slightly deflect from the second section rod 31, the first section rod 3, the second section rod 31, and the third section rod 32 maintain the deflected state, and stably lift the coated substrate roll and withdraw it from the shelf.

[0041] When the insertion rod is straightened, that is, the outward-moving clamping frame 10 clamps it from the top and bottom sides of the inner wall of the roll, the inner wall of the roll no longer resists the pressure block 11, and under the elastic action of the second spring 13, the L-shaped clamping block 12 moves inward and resets, thereby driving the pressure block 11 to move upward and reset. In summary, through the cooperation of the pressure block 11, the L-shaped clamping block 12, and the clamping ring 14, the substrate roll can be straightened after being pulled out, which can ensure that the substrate is more stable during transportation and will not shake due to the swing of the fork rod, reducing the risk during transportation. This design simplifies the operating steps and does not require additional adjustments. The operator can complete the stacking task more quickly and easily. The pressure block 11 and the adjacent L-shaped clamping block 12 are squeezed together.

[0042] like Figure 8As shown, it also includes an anti-skid mechanism for increasing the contact area between the insertion rod and the substrate roll to prevent it from slipping. The anti-skid mechanism is arranged on the third section insertion rod 32. The anti-skid mechanism includes a rotating frame 15, which is rotatably connected to the left side of the third section insertion rod 32. A gear 151 is fixedly connected to the right side of the rotating frame 15. A torsion spring 17 is connected between the rotating frame 15 and the third section insertion rod 32. The torsion spring 17 is wound around the rotating frame 15. A telescopic rod 16 is fixedly connected to the left side of the rotating frame 15. A sliding rod 18 is slidably connected to the left part of the top wall of the third section insertion rod 32. A rack 181 is fixedly connected to the bottom of the sliding rod 18, and the rack 181 is meshed with the gear 151.

[0043] like Fig. 9 As shown, it also includes a control mechanism for determining whether the telescopic rod 16 is used. The control mechanism is arranged on the third section plug rod 32. The control mechanism includes a gear shift 19. The gear shift 19 is slidably connected to the left part of the third section plug rod 32. A screw 20 is rotatably connected to the left wall of the third section plug rod 32. The screw 20 is threadedly connected to the gear shift 19.

[0044] When the inner wall of the roll presses against the pressure block 11 to move it downward, the inner wall of the roll will also press against the sliding bar 18 to drive the rack 181 to move downward. Since the rack 181 is meshed with the gear 151, the rotating frame 15 and the telescopic rod 16 are driven to rotate 180° through the gear 151. The torsion spring 17 is twisted, and the telescopic part of the telescopic rod 16 will extend downward under the action of its own gravity. At this time, the extended telescopic rod 16 and the insertion rod form an inverted seven-character shape, and the extended telescopic rod 16 will hook the coated substrate roll from the left side. According to the previous steps, when the insertion rod is straightened, that is, the outward-moving clamping frame 10 clamps it from the top and bottom sides of the inner wall of the roll, the inner wall of the roll no longer presses against the sliding bar 18, and under the action of the torsion spring 17, the rotating frame 15 will drive the telescopic rod 16 to rotate 180° to reset, and the telescopic part of the telescopic rod 16 will shrink downward to reset.

[0045] When the telescopic rod 16 is not needed, for example, the weight of the coated substrate roll is light, the staff can reversely turn the screw 20 to drive the gear shift 19 to move to the left to circle the telescopic rod 16. Conversely, when the telescopic rod 16 is needed, the screw 20 is turned forward to drive the gear shift 19 to move to the right and reset. In summary, the sliding rod 18, the rack 181, the gear 151, the telescopic rod 16, etc. cooperate with each other to ensure the stability and safety of the coated substrate during the lifting process, thereby improving the stacking efficiency, and then the cooperation between the gear shift 19 and the screw 20 can facilitate the control of whether the telescopic rod 16 is used, thereby improving the flexibility of the device operation.

[0046] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted as limiting the scope of protection in any way. Based on the explanations here, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without paying creative work, and these methods will fall within the scope of protection of the embodiments of the present invention.
