Description

Technical Field

[0001] The present 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 within the warehouse is an important part of supply chain optimization. It is designed 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 levels, ensure that raw materials arrive at the designated location on time and in quantity, support changing 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 handling substrates, automated equipment and procedures are usually relied upon to achieve the transfer and handling 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 transfer. 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

[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 to a symmetrically distributed L-shaped block. A second spring is connected between the L-shaped block and the adjacent mounting column, and a snap ring is fixed in each mounting hole.

[0011] Furthermore, the pressing block and the adjacent L-shaped clamping block are squeeze-fitted.

[0012] Furthermore, it also includes an anti-slip mechanism for increasing the contact area between the insertion rod and the substrate roll to prevent it from slipping. The anti-slip mechanism is arranged on the third section of the insertion rod. The anti-slip 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. A gear is fixed 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.

[0018] The present invention uses the cooperation of the pressing block, the L-shaped clamping block and the clamping ring to straighten the substrate roll after it is 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, thereby reducing the risk during transportation.

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be 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 merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0031] Example 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, the upper left side of the transfer vehicle 1 is slidingly connected to a connecting frame 2, the left side of the connecting frame 2 is fixedly connected to a first section rod 3, the left side of the first section rod 3 is rotatably connected to the second section rod 31, the left side of the second section rod 31 is rotatably connected to the third section 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 a 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 rod 31 and the third section rod 32, and the first slider 6 slides in the first section rod 3 and the second section rod 31.

[0032] like Figure 3 As shown, a mounting column 33 is also included. The upper right side of the second section rod 31 and the third section rod 32 is provided with a mounting column 33, and the upper left side of the first section rod 3 and the second section rod 31 is provided with a mounting hole 34. The mounting columns 33 rotate in the adjacent mounting holes 34.

[0033] When using this 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 turn. 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 press against 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 fully 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 the 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 to another shelf, and the connecting frame 2 is controlled to move downward so that the coated substrate roll is placed on the horizontal plate of the shelf. 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 left and reset, thereby driving the first slider 6 and the second slider 61 to move left and reset. In summary, the insertion rod is first designed to be three sections connected in a rotatable manner, so that when the substrate and the transfer equipment are not completely aligned, it can still be inserted smoothly, without the need to frequently adjust the position of the substrate and the equipment, saving time and labor, and improving the flexibility and work efficiency of operation. The first slider 6 and the second slider 61 are then used to straighten the three sections of the insertion rod into a whole, 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 straighten and lock after insertion, ensuring the stability of the substrate during the transfer process, thereby improving the stacking efficiency.

[0036] Example 2: Based on Example 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 fixing rod 7, which is fixed to the left side of the second slider 61. The first connecting rod 5 and the fixing rod 7 are both slidably connected with a guide frame 8. The two guide frames 8 and the first connecting rod 5 and the fixing rod 7 are connected with a first spring 9. The two first springs 9 are respectively wound around the first connecting rod 5 and the fixing rod 7. The top and bottom walls of the first section insertion rod 3 and the second section insertion rod 31 are both slidably connected with a card frame 10. There are four card frames 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 card frames 10 are opened with inclined slide grooves, and the bosses slide in the adjacent inclined slide grooves. The top and bottom walls of the first section insertion rod 3 and the third section insertion rod 32 are opened with five through holes, and the card frames 10 slide 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 outward-moving clamping frame 10 will clamp the inner wall of the roll from the top and bottom sides, increasing the stability of the coated substrate rolled on the insertion rod. At this time, the inner wall of the roll will support the clamping frame 10, thereby supporting the guide frame 8, forming a stable support 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 to the 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 mutual cooperation of 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 the transportation process, ensuring that the substrate can be stacked smoothly and accurately to 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, which is slidingly connected to the upper part of the two mounting columns 33 respectively. The lower part of the two mounting columns 33 is slidingly connected to symmetrically distributed L-shaped blocks 12. A second spring 13 is connected between the L-shaped block 12 and the adjacent mounting column 33, and 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 snap ring 14, the second spring 13 will deform, and friction will be generated between the snap ring 14 and the L-shaped block 12, thereby making the mounting column 33 and the mounting hole 34 contact more closely, and then when the inner wall of the roll presses against the third section rod 32 and causes it to deflect slightly 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 the coated substrate roll is stably lifted and withdrawn 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 presses against 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. The left part of the top wall of the third section insertion rod 32 is slidably connected to a sliding rod 18. 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 Figure 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 of the rod 32. The control mechanism includes a gear shift 19. The gear shift 19 is slidingly connected to the left part of the third section of the rod 32. A screw 20 is rotatably connected to the left wall of the third section of the 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 and moves it downward, the inner wall of the roll will also press against the slide bar 18 to drive the rack 181 to move downward. Since the rack 181 is meshed with the gear 151, the turret 15 and the telescopic rod 16 are driven to rotate 180 degrees 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 slide bar 18, and under the action of the torsion spring 17, the turret 15 will drive the telescopic rod 16 to rotate 180 degrees to reset, and the telescopic part of the telescopic rod 16 will retract 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 change 19 to move to the left to circle the telescopic rod 16. Conversely, when the telescopic rod 16 needs to be used, the screw 20 is turned forward to drive the gear change 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 change 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.
