Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a deviation correcting device for a plastic film coil conveyor. Background Art

[0002] During the production process of plastic film, in order to facilitate the transportation and storage of the plastic film, the plastic film will be wound on a reel to form a coil after production is completed, and then the coil will be transported to the storage location by transportation equipment.

[0003] After the plastic film coil is wound, it is placed on the conveying equipment and transported to the end point by the conveying equipment. Then, the coil is grabbed by the grabbing equipment and stacked. For example, the patent with the prior art announcement number CN221625143U discloses a plastic film coil conveying mechanism, which lifts and moves the plastic film coil to the position of the frame through an electric conveyor belt. When the plastic film coil moves to the lower side of the frame, the two groups of fixed plates are driven by the supporting device to move to the front and rear sides of the plastic film coil. Then, the two groups of first push cylinders push the two groups of pins to extend toward each other, so that the two groups of pins are respectively inserted into the circular holes at both ends of the plastic film coil winding drum, so that the mechanism grabs the plastic film coil and moves it to different positions or stacks it.

[0004] However, the prior art still has the following defects: since the placement point of the coil on the electric conveyor belt is different each time, and the coil is prone to rolling or swaying during transportation, the position of each coil is different when it moves to the output end of the electric conveyor belt. Although the fixed plate can be moved in multiple directions to connect the latch with the coil, due to the different positions of each coil, position adjustments in different directions and frequencies are required each time it is grabbed, which increases the grabbing and positioning time. At the same time, if the distances between the two fixed plates and the two ends of the coil are different, the fixed plate is likely to cause the coil to slide against the placement surface when it approaches the coil, causing damage to the coil. Summary of the invention

[0005] In view of the problem that the prior art has the problem of time-consuming and inaccurate positioning of plastic film coils, a deviation correcting device for a plastic film coil conveyor is proposed.

[0012] Furthermore, a guide rail frame is slidably connected to one side of the second fixed plate, and the second fixed plate and the guide rail frame are elastically connected via an elastic member, a plurality of limiting wheels are rollingly connected to the guide rail frame, and the limiting wheels are rotatably connected to the positioning plate.

At the same time, the positioning plate moves synchronously with the abutted coil to avoid damage to the coil drum.

[0018] 2. When the coil has completed displacement adjustment on the lifting frame and the flat plate has descended, the connecting plate drives the brake tooth plate to engage with the gear, limiting the rotation of the support roller, so that the coil is stably placed on the lifting frame, avoiding slight displacement of the coil after positioning due to the movement of the equipment, and further ensuring the stability of the coil positioning.

[0019] 3. When the coiled material is transported to the clamping block module after the deviation correction, the coiled material contacts the driving plate under the action of its own weight, driving the arc plate to rotate, so that the upper ends of the two arc plates approach each other to clamp the coiled material, thereby limiting the horizontal displacement of the coiled material. This can avoid the situation where the distances between the two pins on the grabbing device and the coiled material are different, and one of the pins contacts the coiled material first, causing the coiled material to deviate again.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] The directional descriptions such as "left" and "right" in the following embodiments are all based on Figure 1 The indicative description here is only for the convenience of explaining the technical solution and does not impose any substantive limitation.

[0024] Example 1, reference Figure 1-Figure 12 , which is the first embodiment of the present invention, provides a plastic film coil conveyor correction device, including a fixed frame 1 arranged at the lower side of a support arm, a plurality of placement seats 101 are evenly distributed on both sides of the top of the fixed frame 1, a conveying mechanism arranged in the fixed frame 1, and a correction mechanism arranged on both sides of the fixed frame 1; the conveying mechanism includes a driving component 2 installed in the fixed frame 1, and a conveying component 3 arranged on the driving component 2; the driving component 2 includes two rotating shafts 201 rotatably connected to the fixed frame 1, and driving plates connected to the fixed frame 1 are provided at both ends of the rotating shaft 201, and a telescopic The arm, the telescopic arm is connected and fixed to the end of the rotating shaft 201, the transport component 3 includes a flat plate 301 connected to the telescopic arm, and a plurality of lifting frames are evenly distributed on the flat plate 301; the correcting mechanism includes a correcting component 4 installed on the fixed frame 1, and a transmission component 5 installed on the correcting component 4; the correcting component 4 includes a fixed plate 1 401 connected and fixed to the fixed frame 1, one side of the fixed plate 1 401 is connected to a fixed plate 2 402, one side of the fixed plate 2 402 is slidably connected to a positioning plate 405, and the transmission component 5 includes a driving block 501 slidably arranged on the fixed frame 1, and the driving block 501 is used to drive the fixed plate 2 402 to move.

[0025] The plate 301 then moves horizontally to move the coiled material to the adjacent placement seat 101 on the left, and the driving assembly 2 cooperates with the conveying assembly 3 to realize intermittent conveying of the coiled material. During the process of the coiled material located in the middle of the fixed frame 1 being lifted and translated, the plate 301 drives the driving block 501 to rise, so that the two fixed plates 402 approach each other, and drive the positioning plate 405 to contact the end of the coiled material drum, so that the coiled material remains centered on the lifting frame, and then the coiled material is always transported to the leftmost end of the fixed frame 1 in a centered position, and is quickly plugged into the coiled material drum by the two latches approaching each other, so as to grab and stack it.

[0026] Reference Figure 3 Both ends of the rotating shaft 201 are rotatably connected with a U-shaped shaft frame 202, the shaft frame 202 is fixedly installed on the fixed frame 1, and the two rotating shafts 201 are connected by a chain transmission; the driving component 2 also includes a motor 203 fixedly installed on the fixed frame 1, and the output end of the motor 203 passes through the fixed frame 1 and is connected to one of the rotating shafts 201.

[0027] Specifically, the end of the rotating shaft 201 is connected to the shaft frame 202 through a bearing, and the output end of the motor 203 drives one of the rotating shafts 201 to rotate synchronously through a chain. The two rotating shafts 201 rotate synchronously through the chain, so that each telescopic arm moves synchronously on the corresponding driving plate.

[0028] Reference Figure 4 The driving plate includes a bottom plate 204 fixedly connected to the fixed frame 1, and two rectangular plates 205 are fixedly connected to one side of the bottom plate 204; the telescopic arm includes a fixed sleeve 206 fixedly connected to the end of the rotating shaft 201, and a driving rod 207 is slidably connected in the fixed sleeve 206, and one end of the driving rod 207 is rotatably connected to a guide wheel 208, and the guide wheel 208 is rotatably arranged between the two rectangular plates 205.

[0029] Specifically, a zigzag channel with the same spacing is formed between the two rectangular plates 205, the guide wheel 208 is in rolling contact with the zigzag channel, the fixed sleeve 206 rotates synchronously with the rotating shaft 201, and the driving rod 207 and the fixed sleeve 206 slide together, so that the guide wheel 208 makes a zigzag motion in the zigzag channel, and the flat plate 301 moves synchronously with the guide wheel 208, so that the flat plate 301 makes a counterclockwise zigzag motion.

[0030] Reference Figure 2 , Figure 4 , Figure 5 The bottom corners of the flat plate 301 are fixedly connected with support rods 302, and the support rods 302 are rotatably connected to one end of the driving rod 207; the lifting frame includes a base 303 connected and fixed to the flat plate 301, the base 303 is an L-shaped structure, and a plurality of support rollers 304 are evenly distributed on the base 303.

[0031] Specifically, the rotation axis of the support rod 302 and the driving rod 207 and the rotation axis of the guide wheel 208 are located on the same axis, so that the flat plate 301 follows the guide wheel 208 to make a circular motion. When the flat plate 301 rises vertically, the support roller 304 can contact the coil on the placement seat 101 and drive the coil to lift and make it leave the placement seat 101. Then the flat plate 301 moves horizontally to the left, driving the coil to move above the placement seat 101 adjacent to the left. When the flat plate 301 descends vertically, the coil on the support roller 304 gradually contacts the placement seat 101. When the base 303 is lower than the placement seat 101, the coil is stably placed in the current placement seat 101, thereby realizing the cooperation between the driving component 2 and the conveying component 3 to drive the coil to be conveyed intermittently.

[0032] Reference Figure 8 , Fig.10 , Fig.12 A plurality of rotating rods 403 are hinged on one side of the fixed plate 402, the upper rotating rod 403 is hinged to the fixed plate 401, and the lower rotating rod 403 is slidingly connected to the fixed plate 401; a guide wheel 2 502 is rotatably connected to one side of the driving block 501, the guide wheel 2 502 is in rolling contact with the flat plate 301, and a connecting rod 503 is hinged on the other side of the guide wheel 502, and one end of the connecting rod 503 is hinged to the lower rotating rod 403.

[0033] Specifically, the driving block 501 is vertically slidably connected to the limiting hole opened on the fixed frame 1, and the guide wheel 2 502 is arranged on the inner side of the fixed frame 1. The flat plate 301 contacts the guide wheel 2 502 during the rising process, driving the driving block 501 to rise vertically, and the connecting rod 503 drives the lower rotating rod 403 to move. The upper and lower rotating rods 403 cooperate to drive the fixed plate 2 402 to move toward the middle of the fixed frame 1, so that the positioning plates 405 on both sides approach each other until they contact the coil drum on the lifting frame, so that the movement of the coil on the support roller 304 is centered.

[0034] Reference Fig.12 It can be understood that an elastic member is fixedly connected between the bottom surface of the driving block 501 and the limiting hole. When the driving block 501 rises, the elastic member pulls up and accumulates force. When the flat plate 301 descends, the elastic member drives the driving block 501 to descend, ensuring that the fixed plate 402 is quickly reset, so that the positioning plate 405 cancels the contact with the coil.

[0035] Reference Figure 8 , Fig.11 A guide rail frame 404 is slidably connected to one side of the second fixed plate 402, and the second fixed plate 402 and the guide rail frame 404 are elastically connected through an elastic member. A plurality of limiting wheels 406 are rollingly connected to the guide rail frame 404, and the limiting wheels 406 are rotatably connected to the positioning plate 405.

[0036] Specifically, when the positioning plate 405 elastically abuts against the end of the roll, under the action of the abutment force, the positioning plate 405 translates on the guide frame 404 and moves synchronously with the roll, so that the roll and the positioning plate 405 can be prevented from sliding when the positioning plate 405 abuts against the roll, thereby avoiding wear on the roll.

[0037] Among them, a plurality of guide rods are vertically fixed on one side of the fixed plate 402, the end of the guide frame 404 is slidably connected to the guide rod, and the two ends of the elastic member are respectively connected and fixed to the end of the guide frame 404 and the side of the fixed plate 402, so that the guide frame 404 drives a horizontal elastic clearance space to avoid excessive tight contact between the positioning plate 405 and the reel.

[0038] Reference Fig.11 A pull rope 407 is bolted to one side of the positioning plate 405, and a counterweight 408 is fixedly connected to one end of the pull rope 407. A guide wheel 409 is rotatably connected to the fixing plate 402, and the pull rope 407 is rollingly connected to the guide wheel 409.

[0039] Specifically, when the positioning plate 405 moves with the reel, the counterweight block 408 is driven up through the pull rope 407. When the coil is transported, the positioning plate 405 cancels the contact with the reel, and the counterweight block 408 descends under the action of gravity, driving the positioning plate 405 to reset.

[0040] Among them, gravitational potential energy is generated by the height change of the counterweight block 408, so that when the positioning plate 405 moves synchronously with the reel, the pulling force of the counterweight block 408 on the positioning plate 405 changes within a small range, which can maintain a relatively stable abutment force between the positioning plate 405 and the reel, avoiding sliding between the positioning plate 405 and the reel.

[0041] Reference Figure 1 , Figure 5 The support rollers 304 on two bases 303 disposed near the positioning plate 405 are rotatably connected to the base 303 , and the support rollers 304 on the remaining bases 303 are fixedly connected to the base 303 .

[0042] Specifically, when the two positioning plates 405 are close to each other, the rolling support rollers 304 can drive the coil to move its position to avoid damage to the coil. After the coil is positioned and adjusted, the support rollers 304 in the left lifting frame are fixed to prevent the coil from shifting again during transportation and ensure transportation stability.

[0043] It can be understood that the support roller 304 is concavely arranged, and the concave surface is adapted to the thickness of the coil, so that the coil can effectively fit with the concave surface of the support roller 304 when placed on the lifting frame, thereby improving the stability of the coil when placed and moved.

[0044] Example 2, reference Figure 6 , Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a brake unit 6 is installed on the two bases 303 close to the positioning plate 405, and the brake unit 6 includes a connecting plate 601 arranged on the lower side of the flat plate 301, and a plurality of brake tooth plates 602 are fixedly connected to the connecting plate 601. A snap-fitting gear 603 is provided on the upper side of the brake tooth plate 602, and the gear 603 is coaxially connected to the support roller 304; the connecting plate 601 is elastically connected to the flat plate 301 through an elastic member, and both ends of the connecting plate 601 are rotatably connected to guide wheels 3 604, and the guide wheels 3 604 are in rolling contact with the guide plate 102 fixedly connected to the fixed frame 1.

[0045] Specifically, during the vertical ascent of the flat plate 301, the top of the guide wheel 3 604 rolls in contact with the bottom of the guide plate 102, so that the height of the connecting plate 601 remains unchanged when the flat plate 301 continues to rise, so that the brake tooth plate 602 is out of contact with the gear 603. At this time, the support roller 304 connected to the gear 603 can rotate, so as to cooperate with the positioning plate 405 to adjust the positioning of the coil. When the flat plate 301 descends and the guide wheel 3 604 cancels the contact with the guide plate 102, the elastic member drives the connecting plate 601 to rise, so that the brake tooth plate 602 is engaged with the gear 603. At this time, the support roller 304 cannot rotate, so that the coil can be placed stably, so that when the lifting frame completes the positioning adjustment of the coil and moves to the placement seat 101, the coil is prevented from moving, and the centering positioning effect of the coil is further ensured. The rest of the structure is the same as that of Example 1.

[0046] Example 3, reference Figure 1 , Fig.13 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: self-clamping modules 7 are symmetrically provided on both sides of the top of the fixing frame 1, and the self-clamping module 7 includes a hinge seat 701 fixedly connected to the fixing frame 1, and an arc plate 702 is hinged on the hinge seat 701. A driving plate 703 is fixedly connected to the lower end of the arc plate 702, and the arc plate 702 is elastically connected to the hinge seat 701 through an elastic member.

[0047] Specifically, the coiled material after positioning adjustment is finally conveyed to the leftmost side of the fixed frame 1. When the coiled material is arranged between the two arc-shaped plates 702, it contacts the driving plate 703 under the action of its own weight to drive the arc-shaped plate 702 to rotate, so that the upper ends of the two arc-shaped plates 702 are close to each other to clamp the coiled material, thereby limiting the horizontal displacement of the coiled material, thereby preventing the two pins on the grabbing device from having different distances from the coiled material, causing one of the pins to contact the coiled material first, causing the coiled material to shift again.

[0048] The inner arc surface of the arc plate 702 is adapted to the thickness of the coil, and an anti-skid rubber pad is fixed on the inner arc surface to increase the friction when in contact with the coil, and the hinge of the hinge seat 701 and the arc plate 702 is lower than the center height of the arc plate 702, so that when the self-clamping module 7 does not clamp the coil, the elastic member drives the arc plate 702 to rotate, and the upper end spacing of the two arc plates 702 is greater than the diameter of the coil, so that the coil falls into the self-clamping module 7. The rest of the structure is the same as that of Example 2.

[0049] In summary, the working principle of the present invention is as follows: the wound coil is placed on the placement seat 101 on the far right of the fixed frame 1, and the motor 203 drives one of the rotating shafts 201 to rotate. The two rotating shafts 201 rotate synchronously through the chain, driving the sliding cooperation between the rod 207 and the fixed sleeve 206, so that the guide wheel 208 makes a circular motion in the circular channel, and the flat plate 301 moves synchronously with the guide wheel 208. When the flat plate 301 rises vertically, the support roller 304 can contact the coil on the placement seat 101 and drive the coil to be lifted and leave the placement seat 101. Then the flat plate 301 moves horizontally to the left, driving the coil to move above the placement seat 101 adjacent to the left. When the flat plate 301 descends vertically, the coil on the support roller 304 gradually contacts the placement seat 101. When the base 303 is lower than the placement seat 101, the coil is stably placed in the current placement seat 101, thereby realizing the cooperation between the driving component 2 and the conveying component 3 to drive the coil to be conveyed intermittently.

[0050] At the same time, when the flat plate 301 rises, it contacts the guide wheel 2 502, driving the driving block 501 to rise vertically, and the connecting rod 503 drives the rotating rod 403 on the lower side to move. The rotating rods 403 on the upper and lower sides cooperate to drive the fixed plate 2 402 to move toward the middle of the fixed frame 1, so that the positioning plates 405 on both sides are close to each other until they contact the coil drum on the lifting frame, so that the movement of the coil on the lifting frame is centered and adjusted. After the adjustment is completed, the coil is transported to the self-clamping module 7, and under the action of the coil's own weight, it contacts the driving plate 703 and drives the arc plate 702 to rotate, so that the upper ends of the two arc plates 702 are close to each other to clamp the coil, and the horizontal displacement of the coil is limited, which is convenient for the gripping device's pin to quickly position and plug with the coil. When the gripping device's pin is plugged with the coil drum, it rises vertically, and the elastic member drives the arc plate 702 to rotate to cancel the coil limit, so that the coil leaves the self-clamping module 7.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
