Description
Technical Field
[0001] The utility model relates to the technical field of placing electrode sheet transport rolls, in particular to an electrode sheet transport roll placing rack. Background Art
[0002] Electrode sheets are an important component of batteries. During the battery production process, electrode sheets are transported in rolls. The rolled electrode sheets are rolled on transfer reels from the raw material production factory to the battery production factory. In some links in the middle, the wider electrode sheets are cut into narrow electrode sheets that meet the requirements of the production process, and then rolled into small rolls on reels and transported to the required locations.
[0003] It can be seen that the electrode sheet transport reel is always indispensable in the process from raw materials to battery components. The mass of the rolled electrode sheet is similar to that of a metal ingot of the same volume, and its weight is extremely heavy, so the strength requirement for the reel is relatively high, which also causes the reel itself to have a larger weight.
[0004] After the raw materials of the electrode sheet are taken off the roll, the empty roll is idle and needs to be collected and transported to the location where the original materials are reeled in for use. If the empty roll is placed directly on the ground, there is no gap between the roll and the lifting device for the lifting and transporting equipment to insert, making it difficult to lift and transport the heavier roll.
[0005] If the roll is placed on a rack with multiple rows of placement platforms in the vertical direction, placing heavier rolls higher may cause the rack to have a higher center of gravity, and there is a risk of the rack tipping over. Utility Model Content

[0025] The elastic buffer has a blocking state in which it partially extends into the placement groove, and a compressed state in which it is received in the frame;
[0026] When the extrusion force applied to the elastic buffer inside the placement groove is greater than the upper limit of the force applied to the elastic buffer, the elastic buffer is converted from a blocking state to a compression state;

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments of the present invention.
[0052] Example 1
[0053] See also Figure 1-Figure 6 The present invention provides an electrode sheet transfer roll placement rack, comprising:
[0054] A base 1 and a frame 2;
[0055] The base 1 has a placement surface 11, and the placement surface 11 can be used to place the reel 4;
[0056] The frame 2 is disposed on the placement surface 11, and a placement groove 21 is disposed inside the frame 2, the width of the placement groove 21 is greater than the diameter of the reel 4, and the length of the placement groove 21 is greater than the length of the reel 4;
[0057] The height direction of the placement groove 21 extends in a direction away from the placement surface 11, and the height direction dimension of the placement groove 21 is greater than the sum of the diameters of the plurality of rolls 4. An end of the placement groove 21 away from the placement surface 11 is provided with an entrance 211 for placing the rolls;
[0058] Moreover, the bottom of the placement groove 21 is communicated with the placement surface 11 , and an outlet 212 for a transfer roll to roll out is opened on the side of the placement groove 21 .
[0059] In order to facilitate the placement of rolls, the distance between the upper and lower adjacent platforms needs to be larger. When the distance is larger, the height of the upper platform from the ground will also increase, which will lead to unstable center of gravity. The number of platforms that can be installed in the vertical direction is also limited, resulting in a limited number of rolls that can be placed.
[0060] In the technical solution provided by the utility model, the reel is loaded into the placement groove 21, and multiple reels can be placed in the height direction of the placement groove 21, and the reels loaded in the vertical placement groove 21 are adjacent to each other up and down without any gap, so that the height of the placement groove 21 is not high after loading multiple reels, thereby reducing the height of the placement frame and lowering the center of gravity.
[0061] After the roll is loaded into the placement groove 21 from the entrance 211, the lowermost roll rolls out from the outlet 212 opened at the bottom side of the placement groove 21 and falls on the placement surface 11. When the roll needs to be taken out, it can be taken out from the placement surface 11 above the base 1.
[0062] The width and length of the placement groove 21 are both greater than the diameter and length of the roll to prevent the roll from getting stuck when it is loaded into the placement groove 21. Preferably, the width of the placement groove 21 is 0.5-3CM greater than the diameter of the roll.
[0063] In some embodiments, the width of the placement slot 21 can also be set to a width for placing multiple rolls horizontally, so that multiple rolls can be placed simultaneously in the horizontal direction of the placement slot 21 to increase the placement amount of rolls.
[0064] In some embodiments, two groups of placement slots 21 may be provided on a base 1. The two groups of placement slots 21 are arranged back to back, which can concentrate the center of gravity of the placed rolls in the middle of the placement frame and increase the number of rolls that can be placed.
[0065] In some embodiments, a moving wheel 14 is provided below the base 1 , and the moving wheel 14 has a locking brake mechanism. After the reel is placed, the placement rack and the reel can be transferred together through the moving wheel 14 .
[0066] Example 2
[0067] Reference Figure 2 , Figure 3 , further, a first guide surface 213 is provided at the bottom of the placement groove 21, and the first guide surface 213 is provided on the opposite side of the outlet 212;
[0068] The two opposite sides of the first guide surface 213 are respectively arranged near the placement surface 11 and the side wall of the placement groove 21 facing the outlet 212 in the width direction;
[0069] The first guide surface 213 is an arc surface, and the outlet 212 of the arc surface is oriented toward the inside of the placement groove 21;
[0070] Moreover, the arc surface is connected to the side wall of the placement groove 21 and is tangent to the side wall of the placement groove 21 .
[0071] The placement surface 11 is arranged on the bottom surface. When the roll falls on the placement surface 11, if the roll falls vertically on the placement surface 11, a large impact force will be exerted on the placement surface 11, and the placement surface 11 will be easily damaged after being used several times.
[0072] At the bottom of the placement groove 21, a first guide surface 213 is set on the opposite side of the outlet 212. When the roll falls downward, the bottom of the roll contacts not the flat placement surface 11 but the inclined first guide surface 213. The first guide surface 213 can remove most of the impact force of the roll and make the roll roll downward.
[0073] The arc-shaped first guide surface 213 causes the falling roll to continue rolling toward the outlet 212. The first guide surface 213 tangent to the side wall of the placement groove 21 reduces the front angle facing the falling roll, minimizes the impact from the roll, and reduces the impact and vibration of the entire placement rack when the roll contacts the first guide surface 213.
[0074] Example 3
[0075] Reference Figure 2 Furthermore, a blocking block 12 is provided on one end of the placement surface 11 away from the placement groove 21, and the interval between the blocking block 12 and the outlet 212 is greater than the diameter of a roll;
[0076] A buffer arc surface 121 is formed on one side of the blocking block 12 close to the outlet 212 , and the outlet 212 direction of the buffer arc surface 121 faces one side of the outlet 212 .
[0077] The blocking block 12 is used to prevent the roll from rolling down from the side of the placement surface 11 and falling onto the ground directly after rolling out from the outlet 212.
[0078] A buffer arc surface 121 is provided on the blocking block 12 to prevent the rolls from colliding with each other on the blocking block 12. When the roll rolls down, the buffer arc surface 121 converts the gravitational potential energy of the roll into friction between the buffer arc surface 121 and the kinetic energy of the buffer arc surface 121 climbing upward, thereby avoiding direct collision with the blocking block 12 and reducing the service life of the blocking block 12.
[0079] Example 4
[0080] Reference Figure 2 , Figure 3 , further, an inclined material receiving surface 214 is provided at the inlet 211, and the inclined material receiving surface 214 and the outlet 212 are provided on the same side of the placement groove 21;
[0081] The height of the inclined material receiving surface 214 away from the side wall of the placement groove 21 is greater than the height close to the side wall of the placement groove 21;
[0082] Moreover, a second guide surface 215 is provided between the inclined material receiving surface 214 and the side wall of the placement groove 21 . The second guide surface 215 is an arc surface. The second guide surface 215 is tangent to the inclined material receiving surface 214 and the side wall of the placement groove 21 .
[0083] The inclined receiving surface 214 is used for placing the roll from the entrance 211, providing a placement plane inclined toward the entrance 211. When the roll is placed on the inclined placement surface 11, it can roll from the inclined receiving surface 214 to the placement groove 21 by gravity.
[0084] The second guide surface 215 is used for the roll to roll along the second guide surface 215 below when rolling down, so as to prevent the roll from directly flying off the inclined material receiving surface 214 and generating impact vibration inside the placement groove 21.
[0085] Example 5
[0086] Reference Figure 2Furthermore, a deceleration buffer plate 22 is provided at the entrance 211, and the deceleration buffer plate 22 and the second guide surface 215 are arranged on opposite sides of the placement groove 21 in the width direction;
[0087] The deceleration buffer plate 22 has a buffer plane 221, and the buffer plane 221 is arranged on a side facing the second guide surface 215;
[0088] Furthermore, the minimum distance between the buffer plane 221 and the second guide surface is the diameter of the reel.
[0089] When the roll falls from the inclined receiving surface 214 , the speed of the roll is too fast and can still contact and collide with the side wall of the placement groove 21 opposite to the second guide surface 215 .
[0090] The deceleration buffer plate 22 is used to prevent the reel from colliding with the side wall of the placement groove 21 when the speed is too fast. The distance between the flat deceleration buffer surface and the second guide surface 215 of the lake surface along the falling of the reel ranges from a large opening at the beginning to a minimum distance equal to the diameter of the reel in the middle position, and then to a gradually larger opening later.
[0091] When the roll rolls from the maximum opening to the minimum distance in the middle, the opening gradually decelerates the roll from large to small, and the roll rolls down again after the speed is reduced, reducing the impact of the roll on the placement rack when it is collected.
[0092] In some embodiments, the deceleration buffer plate 22 is made of an elastic rubber plate or a plastic plate, which can reduce the impact of the reel and consume the potential energy of the reel.
[0093] Example 6
[0094] Reference Figure 3-Figure 6 , further, it also includes an elastic buffer, which is arranged on the frame 2;
[0095] The elastic buffer has a blocking state in which it partially extends into the placement groove 21, and a compressed state in which it is received in the frame 2;
[0096] When the extrusion force applied to the elastic buffer member in the placement groove 21 is greater than the upper limit of the force applied to the elastic buffer member, the elastic buffer member is converted from the blocking state to the compression state;
[0097] When the squeezing force on the elastic buffer that is greater than the upper limit of the force of the elastic buffer is released, the elastic buffer is converted from the compression state to the blocking state.
[0098] The elastic buffer is used to decelerate the rolls entering the placement slot 21 to prevent the rolls from falling into the outlet 212 at too high a speed, which may damage the outlet 212 and the placement surface 11 after long-term use. In particular, when the first roll is placed, there is no other roll below to block it, and the falling distance is the longest and the gravitational potential energy is the greatest.
[0099] The part of the elastic buffer extending into the placement groove 21 occupies the falling space of the roll in the placement groove 21, and its passing distance is less than the diameter of the roll. When the roll passes through here, it consumes its falling potential energy to squeeze the part of the elastic buffer extending into the placement groove 21 out of the placement groove 21, and then continues to fall downward, thereby reducing the falling speed of the roll.
[0100] The upper limit of the force of the elastic buffer can be adjusted according to demand, and elastic buffers with different force sizes can be replaced.
[0101] In some embodiments, the elastic buffer 3 can be configured as an elastic rubber block, or a rotating rod with an elastic member.
[0102] Example 7
[0103] Reference Figure 3-Figure 6 , further, the elastic buffer 3 is respectively arranged at the end section of the second guide surface 215, the entrance section of the first guide surface 213 and the middle section of the side wall opposite to the outlet 212 in the width direction of the placement groove 21;
[0104] At least two sets of elastic buffer members 3 are respectively arranged on the end section of the second guide surface 215, the entrance section of the first guide surface 213 and the middle section of the side wall opposite to the outlet 212 in the width direction of the placement groove 21;
[0105] Furthermore, at least two groups of elastic buffer members 3 are symmetrically arranged at two ends of the placement groove 21 in the length direction.
[0106] The end section of the second guide surface 215 is the starting stage of acceleration after the reel leaves the deceleration buffer plate 22. The middle section of the side wall of the placement groove 21 is the section with the least deceleration facilities in the placement groove 21. After the reel enters the first guide surface 213, the gravitational potential energy will be blocked. The greater the gravitational potential energy, the stronger the impact vibration it generates.
[0107] Elastic buffers 3 are provided at the above-mentioned positions to continuously buffer the falling process of the roll, thereby reducing the impact of the falling roll on the placement rack as a whole.
[0108] When the roller falls from the placement groove 21, one end may fall faster and the other end may fall slower in the length direction, and the roller may get stuck at the outlet 212 when entering the lower part. Elastic buffers 3 are respectively provided at both ends of the placement groove 21 in the length direction, so that the falling speeds of the two ends of the roller are consistent, which can avoid the roller from getting stuck.
[0109] Example 8
[0110] Reference Figure 5 , Figure 6 Furthermore, the elastic buffer member 3 is a buffer torsion spring 31, and the buffer torsion spring 31 is disposed on the fixed shaft 32, and the fixed shaft 32 is connected and fixed to the frame body 2;
[0111] The buffer torsion spring 31 has a free end 311 and a fixed end 322. The free end 311 extends into the placement slot 21, and the fixed end 322 is fixedly connected to the fixed plate 33. The buffer torsion spring 31 consumes the gravitational potential energy of the reel through the relative twisting of the free end 311 and the fixed end 322.
[0112] Example 9
[0113] Reference Figure 5 Further, the buffer torsion spring 31 comprises a first torsion spring 313 and a second torsion spring 314, and the free ends 311 of the first torsion spring 313 and the second torsion spring 314 are arranged adjacent to each other;
[0114] The free ends 311 of the first torsion spring 313 and the second torsion spring 314 are fixedly connected.
[0115] When a single set of torsion springs rotate, the free end 311 may deform along the axis of the coil spring in addition to the deformation in the rotation direction. This deformation beyond the design requirements is prone to plastic deformation after a long period of use and is difficult to recover.
[0116] By providing the first spring and the second spring and fixing the free ends 311 of the first spring and the second spring, the axial deformation of the free end 311 is limited, and the free end 311 can only rotate in the axial direction, thereby preventing the buffer torsion spring 31 from plastic deformation.
[0117] Example 10
[0118] Reference Figure 3 , Figure 4 , Figure 6 Further, the frame body 2 includes a support frame 23, a limit frame 24 and an end plate 25, the support frame 23 is arranged on a side away from the placement slot 21 in the width direction and opposite to the outlet 212, and the limit frame 24 is arranged on a side of the placement slot 21 in the width direction where the outlet 212 is arranged;
[0119] The support frame 23 is fixedly connected to the placement surface 11, and the end plate 25 is fixedly connected to the ends of the support frame 23 and the limiting frame 24, so as to fix the support frame 23 and the limiting frame 24;
[0120] The base 1 and the limiting frame 24 are provided with a material receiving notch 13 in the length direction of the placement groove 21, and the material receiving notch 13 is provided for the rotating drum transport tool to contact with the reel.
[0121] The support frame 23, the limiting frame 24 and the end plate 25 are together enclosed to form the placement groove 21. The limiting frame 24 is fixedly connected to the support frame 23 through the end plate 25, and does not contact the placement surface 11. The gap between the limiting frame 24 and the placement surface 11 is the outlet 212 of the placement groove 21. The inclined material receiving surface 214 is arranged on the end of the limiting frame 24 away from the outlet 212, and the deceleration buffer plate 22 is arranged on the end of the support frame 23 away from the placement plate.
[0122] The base 1 and the limiting frame 24 are both composed of multiple groups of frames arranged in an array along the length direction of the placement groove 21, and are fixedly connected by cross bars. The gap between the frames in the length direction is the material receiving gap 13. Forklifts and other transport tools can extend from the material receiving gap 13 to the bottom of the inclined material receiving surface 214 or the placement surface 11 to perform the operations of placing and taking out the rolls.
