Description

Technical Field

[0001] This invention relates to the field of coil material storage and feeding, and more particularly to a coil material storage and feeding device and a coil material feeding method. Background Technology

[0002] Automatic bending machines primarily use coiled metal blades, commonly referred to as coiled blades, for bending and cutting into predetermined shapes, such as sheet molds used in cardboard box manufacturing. Typically, the coiled blades are stored in a blade tray and manually fed into the bending machine. When a blade needs to be changed, it must be manually rewound back into the blade tray, the tray removed, another tray of blades installed, and the process of feeding the blade back into the bending machine repeated. Some automatic lifting blade magazine devices store two or more trays of blades in a tiered magazine, with the lifting magazine replacing the removal and replacement of the other tray. However, manual rewinding of the blades back into the blade tray or manual retrieval of the tail blade is still required, along with manually raising and lowering the magazine to another level, and then repeating the manual feeding process. Both methods require manual blade feeding and returning, increasing the labor intensity for workers and resulting in lower processing efficiency.

[0003] Existing chain-type automatic lifting tool magazine devices are limited by the weight of the tool loading disc, and the number of tool loading discs usually does not exceed 5. The drive unit, drive servo motor and accelerator need to be selected with larger specifications, which is not conducive to cost control and factory space utilization. In addition, existing chain-type automatic lifting tool magazines also have the problem of chain breakage and tool magazine breakage due to the high load of the drive chain driving the tool magazine up and down.

[0004] Typically, existing automatic bending machines are used in conjunction with a feeding device. When the feeding device delivers the cutting material, the material's curvature can affect processing and potentially impact subsequent processing quality and efficiency, as the blade's position may change. Current technology generally uses a pressure cylinder connected to a clamping block (or connecting rod), which in turn connects to a pressure roller. When the pressure cylinder actuates, the clamping block (or connecting rod) applies pressure to the blade. However, this method has a vulnerability where excessive pressure from the pressure roller can cause the blade to become stuck in the pressure roller. Summary of the Invention

Detailed Implementation

[0047] like Figures 1 to 9As shown, this invention discloses a die-rolling material storage and feeding device, including a main support 1, a die-rolling disc box 2, and a die-rolling feeding mechanism 3. The die-rolling disc box 2 is disposed within the main support 1 and contains multiple layers of die-rolling discs 201. Each of the multiple layers of die-rolling discs 201 has a cutting outlet 21 on the same side. The main support 1 is provided with a lifting mechanism for driving the die-rolling disc box 2 to rise and fall. The die-rolling feeding mechanism 3 is fixed to one side of the main support 1 and corresponds to the position of the cutting outlet 21 of the die-rolling discs 201. The die-rolling feeding mechanism 3 includes a feeding bracket 301 and a sliding bracket 301. The sliding support plate 302 and the blade clamping mechanism 303 are provided. The feeding bracket 301 is provided with a telescopic mechanism 304 that can drive the sliding support plate 302 to move into the cutter head box 2. The blade clamping mechanism 303 is fixed to one end of the sliding support plate 302 near the cutter head box 2. The blade clamping mechanism 303 includes a feeding drive wheel 305 and a feeding driven wheel 306 that can press against one side of the feeding drive wheel 305. The feeding drive wheel 305 is driven by a servo motor 307. A pressing cylinder 308 is provided on one side of the feeding driven wheel 306. In some embodiments, the servo motor 307 drives a pair of reduction gear transmission rollers to feed the blade. Specifically, the blade clamping mechanism 303 also includes a driving pinion and a driving gear that mesh with each other. The driving gear and the feeding drive wheel 305 act on the same shaft. A rolling bearing is also installed on the same shaft to reduce friction loss between the shaft and the bearing seat. The servo motor 307 drives the driving pinion and the driving gear and drives the feeding drive wheel 305 to rotate.

[0048] The cutter head box 2 is lifted by a lifting mechanism, so that its corresponding cutter loading disc 201 corresponds to the cutting blade feeding mechanism 3. Then, the blade clamping mechanism 303 of the cutting blade feeding mechanism 3 moves towards the blade outlet 21 of the corresponding cutter loading disc 201 in the cutter head box 2 through the telescopic mechanism 304, until the blade of the cutter loading disc 201 enters between the feeding drive wheel 305 and the feeding driven wheel 306. At this time, the feeding driven wheel 306 presses against the feeding drive wheel 305 through the pressing cylinder 308. At the same time, the feeding drive wheel 305 starts to rotate under the drive of the servo motor 307, so that the cutting blade is pulled out from the cutter loading disc 201 until it is transported into the bending machine. Conversely, unused cutting blades can be sent back to the cutter loading disc 201, and then another cutter loading disc 201 can be selected to complete the same action.

[0049] This invention, by incorporating a liftable cutter head box 2 and a blade clamping mechanism 303 that extends into the cutter head box 2, achieves automatic lifting and lowering of the cutting blade, automatic blade delivery into the bending machine, and automatic blade return and tail blade retrieval, significantly improving processing efficiency and reducing worker workload. Furthermore, this invention allows for adjustment of the distance between the blade clamping mechanism 303 and the outlet 21, and between the blade clamping mechanism 303 and the feeding and straightening mechanism 319, through the movement of the sliding support plate 302. This facilitates stable clamping and transmission of the cutting material by the cutting blade feeding mechanism 3.

[0050] The blade clamping mechanism described in this technical solution further includes a drive wheel bracket 315 fixed to the upper end of the sliding support plate 302 and a driven wheel bracket that can slide laterally within the drive wheel bracket 315. The feeding drive wheel 305 is longitudinally disposed within the drive wheel bracket 315, and the feeding driven wheel 306 is longitudinally disposed within the driven wheel bracket. The upper end of the drive wheel bracket 315 is provided with a servo motor 307 for driving the feeding drive wheel 305 to rotate. The side of the drive wheel bracket 315 near the feeding driven wheel 306 is also provided with a clamping cylinder 308, and the cylinder rod of the clamping cylinder 308 is connected to the driven wheel bracket.

[0051] In some embodiments, the blade clamping mechanism 303 further includes a feed guide block 316 located at one end of the cutter head box 2 near the sliding support plate 302. The feed guide block 316 is provided with a feed guide groove 317 and a feed roller 318 located below the feed guide groove 317.

[0052] Generally, automatic bending machines are used in conjunction with a feeding device. When the feeding device feeds the cutting material, the material may be bent, affecting processing and potentially impacting subsequent processing quality and efficiency. The blade's feeding position may also change. To stabilize the blade's feeding position, existing technology typically uses a pressure cylinder connected to a clamping block (or connecting rod), which in turn connects to a pressure roller. When the pressure cylinder actuates, the clamping block (or connecting rod) applies pressure to the blade. However, this solution has a drawback: excessive pressure from the pressure roller can cause the blade to become stuck in the pressure roller. To solve the above-mentioned technical problems, in some embodiments, the cutting blade feeding mechanism 3 further includes a pressure wheel 309 located at the end of the sliding support plate 302 away from the cutter head box 2, a pressure wheel cylinder 310 that drives the pressure wheel 309 to move up and down, and a pressure wheel locking cylinder 311 for limiting the pressure wheel 309. During operation, when the pressure wheel cylinder 310 drives the pressure wheel 309 to press at the appropriate position of the blade fed by the blade clamping mechanism, the pressure wheel locking cylinder 311 actuates to press the knurled pressure block onto the upper end of the fixing block used to fix the pressure wheel 309, so that the pressure wheel 309 is locked at a fixed height. In this way, when the blade moves, the pressure of the blade on the pressure wheel 309 remains unchanged, and the blade will not jam the compression wheel. The pressure wheel 309 also ensures the smooth feeding of the blade.

[0053] In this technical solution, the upper end of the sliding support plate 302 is provided with a pressure wheel bracket 312, the upper end of the pressure wheel bracket 312 is provided with a pressure wheel cylinder bracket 313, the pressure wheel cylinder 310 is fixed to the upper end face of the pressure wheel cylinder bracket 313, the pressure wheel locking cylinder 311 is fixed to the side of the pressure wheel cylinder bracket 313, the upper end of the pressure wheel 309 is provided with a pressure wheel connecting plate connected to the cylinder rod of the pressure wheel cylinder 310, the cylinder rod of the pressure wheel locking cylinder 311 is provided with a pressure head that can press against the pressure wheel connecting plate, the pressure wheel 309 is placed inside the upper part of the pressure wheel bracket 312, the lower part of the pressure wheel bracket 312 is also provided with a conveying wheel, and a blade conveying clamp 314 for blade conveying and limiting is also provided between the conveying wheel and the pressure wheel 309.

[0054] In this technical solution, the telescopic mechanism 304 includes a telescopic cylinder, a telescopic slider, and a telescopic slide rail. The telescopic slide rail is located on the lower end face of the sliding support plate 302. The telescopic slider works in conjunction with the telescopic slide rail and is fixedly connected to the feeding bracket 301. One end of the telescopic cylinder is connected to the feeding bracket 301, and the other end of the telescopic cylinder is connected to the sliding support plate 302. Through the telescopic cylinder, the telescopic slide rail, and the telescopic slider, the operation of the blade clamping mechanism 303 can be precisely and stably controlled, and the functions of automatic blade feeding, automatic blade return, and tail blade recovery of the rolled material can be realized. Moreover, the structure and control are simple, and the manufacturing cost is also low.

[0055] In some embodiments, the cutting blade feeding mechanism 3 further includes a feeding straightening mechanism 319 fixed on the feeding bracket 301. The feeding straightening mechanism 319 includes a straightening support plate 320 disposed above the side of the sliding support plate 302 away from the blade clamping mechanism 303, and multiple sets of feeding straightening rollers disposed on the straightening support plate 320 and arranged in the blade conveying direction. The multiple sets of feeding straightening rollers include fixed feeding straightening rollers 321 disposed at both ends of the straightening support plate 320 and movable feeding straightening rollers 322 located in the middle of the straightening support plate 320. The movable feeding straightening rollers 322 are provided with straightening roller sliding brackets 323 that can slide left and right along the vertical direction of the straightening support plate 320. A movable straightening cylinder 324 for driving the straightening roller sliding brackets 323 to move left and right is also fixed on one side of the feeding bracket 301.

[0056] In this technical solution, such as Figure 2 and Figure 3As shown, the lifting mechanism includes a longitudinally arranged lifting support plate 202, a fixed pulley assembly 203, a movable pulley 204, a counterweight 205, a lifting drive motor 206, and a connecting chain 207. The lifting support plate 202 has a first linear sliding guide rail 208 and a linear sliding rack 210 longitudinally arranged on both sides. The cutter head box 2 has a first lifting slider adapted to the first linear sliding guide rail 208 on one side. The lifting drive motor 206 has a drive gear adapted to the linear sliding rack 210. The lifting support plate 202 also has a second linear sliding guide rail 209 longitudinally arranged on the side with the linear sliding rack 210. The counterweight 205 is fixedly connected to the lifting drive motor 206. The fixed pulley assembly 203 includes a fixed pulley bracket 212 and two fixed pulleys 213 arranged in a straight line fixed to the fixed pulley bracket 212. The fixed pulley bracket 212 is fixed to the main support frame. At the upper end, the movable pulley 204 is fixed to the upper end of the cutter head box 2. In this embodiment, the movable pulley 204 is fixedly connected to the center of gravity of the automatic lifting cutter magazine. One end of the connecting chain 207 is fixed to one end of the fixed pulley bracket 212. The other end of the connecting chain 207 passes through the movable pulley 204 and two sets of fixed pulleys 213 in sequence and is connected to the lifting drive motor 206. This lifting mechanism arranges the relatively heavy cutter head box component on one side of the lifting support plate, and the lifting drive motor and counterweight are arranged on the other side of the lifting support plate. The movable pulley is fixedly installed at the center of gravity of the cutter head box, so that the weight of the cutter head box component can be evenly transmitted and distributed to the whole machine frame through multiple chains. This not only helps to optimize the force balance of each component of the cutter head box and enhance the safety of the chain-type cutter head box traction transmission, but also reduces the driving load of the lifting drive motor, thereby relatively reducing the height of the lifting mechanism, simplifying the overall structure and reducing the overall manufacturing cost.

[0057] In this technical solution, one end of the lifting drive motor 206 is fixedly connected to a lifting support base, the drive gear is disposed in the lifting support base, the guide clamping roller is disposed on the lifting support base, the counterweight block 205 is fixedly connected to the lifting drive motor through the lifting support base, and the connecting chain 207 is connected to the lifting drive motor 206 through the lifting support base.

[0058] refer to Figure 4 and Figure 5The lifting mechanism further includes a chain breakage anti-fall mechanism, which includes a strip-shaped limiting baffle 211, a safety claw 215, a hinged bracket 216, a connecting rod 217, a sliding bracket 218, a push rod 219, and a sliding block 220. The strip-shaped limiting baffle 211 is longitudinally arranged on the side of the lifting support plate 202 where the first linear sliding guide rail 208 is provided, and the strip-shaped limiting baffle 211 is provided with multiple longitudinally distributed anti-fall blocks 214. The hinged bracket 216 is fixed to the upper end of the cutter head box 2 near the lifting support plate 202. The safety claw 215 is hinged to the hinged bracket 216, and a tension spring 221 is provided between the end of the safety claw 215 away from the lifting support plate 202 and the hinged bracket 216. The end of the safety claw 215 near the lifting support plate 202 is for locking. When the locking end is lifted, it can be locked onto the anti-fall block 214. The sliding bracket 218 is fixed to the upper end of the cutter head box 2 and located between the hinge bracket 216 and the movable pulley 204. The push rod 219 is laterally slidably disposed on the sliding bracket 218. The sliding block 220 is disposed at the end of the push rod 219 near the movable pulley 204 and abuts against the connecting chain 207. A compression spring 222 is provided between the sliding block 220 and the sliding bracket 218. A hook 224 is provided at the end of the push rod 219 near the hinge bracket 216. One end of the connecting rod 217 is fixed to the end of the safety claw 215 near the sliding bracket 218. The other end of the connecting rod 217 is provided with a stop bar 223 extending to both sides. The hook 224 is hung on the stop bar 223.

[0059] In some embodiments, there are two first linear sliding guides, which are arranged parallel to each other at both ends of the lifting support plate. This provides a better guiding and limiting effect, enabling the cutter head box to rise and fall smoothly.

[0060] like Figure 2 and 3 As shown, the movable pulley 204 and the fixed pulley assembly 203 are arranged in two rows in parallel. Each row of the movable pulley 204 and each row of the fixed pulley 213 has a double-row gear structure. There are four connecting chains 207, and each pair of connecting chains 207 corresponds to one row of fixed pulley 213 and movable pulley 204, thereby reducing the force on the chain traction structure and improving the safety of lifting the cutter head box 2.

[0061] Under normal circumstances, the sliding stop 220 is blocked by the connecting chain 207, preventing the hook 224 of its push rod 219 from pulling the connecting rod 217. The connecting rod 217 and safety claw 215 are in the upper position under the action of the tension spring 221, while the locking end of the safety claw 215 is in the lower position. At this time, the locking end will not contact the strip-shaped limit baffle 211, and the cutter head box 2 can move up and down normally. When the connecting chain 207 breaks, the sliding stop 220 and... The push rod 219 will slide towards the movable pulley 204 under the action of the compression spring 222. At this time, the hook 224 at the other end of the push rod 219 will simultaneously pull the stop bar 223 on the connecting rod 217 to rotate downward. At this time, the locking end of the safety claw 215 will rotate upward. When the cutter head box 2 falls, the locking end of the safety claw 215 will lock onto the anti-fall block 214 on the strip-shaped limit baffle 211 on one side, thereby realizing the anti-fall protection of the cutter head box 2 and making it safer.

[0062] like Figure 5 As shown, an alarm switch 225 can also be installed below one end of the safety claw 215 connected to the connecting rod 217. When the connecting chain 207 breaks, the safety claw 215 at one end of the connecting rod 217 will rotate downward, which will trigger the alarm switch 225, thereby reminding the equipment of a fault or directly controlling the shutdown operation.

[0063] according to Figure 8 As shown, the blade loading disc 201 includes a base shell 2011, an annular blade guard plate 2012, a cover plate 2013, a blade straightening roller 2014, and a manual blade clamping roller 2015. The manual blade clamping roller 2015 is located inside the base shell 2011 at one end near the blade outlet 21. The annular blade guard plate 2012 is located inside the base shell 2011 at the other end, and has a blade outlet clearance notch on the side near the blade outlet 21. A plurality of guide rollers are spaced apart on the annular blade guard plate 2012. In 2016, the cover plate 2013 covers the annular blade guard plate 2012. The blade straightening roller 2014 is located between the annular blade guard plate 2012 and the manual blade clamping roller 2015. The blade material is installed between the annular blade guard plate 2012 and the cover plate 2013. The free end of the blade passes through the blade exit notch, is straightened by the blade straightening roller 2014, and is then installed in the manual blade clamping roller 2015. Finally, it exits from the blade exit port 21, waiting for the blade to be fed into the bending machine. Of course, in addition to automatic blade delivery, the blade loading disc can also automatically retract or return the blade.

[0064] In this technical solution, the tool loading disc 201 further includes a tail blade recovery mechanism, which includes a tail blade clamping roller 2018 and a lotus-shaped gear 2017. The lotus-shaped gear 2017 is located at the center of the annular blade guard plate 2012. The tail blade clamping roller 2018 is located between the manual blade clamping roller 2015 and the blade exit clearance notch of the annular blade guard plate 2012, and is on the same straight line as the manual clamping roller and the blade exit port 21. When the blade reaches the end of its stroke, due to the structural limitations of the bending machine, a section of the tail blade is unusable and needs to be retrieved. The tool loading disc 201, equipped with a tail blade clamping roller 2018 and a lotus-shaped gear 2017, allows the tail blade to be retracted into the tool loading disc 201 via the blade clamping mechanism 303. As the tail blade retracts, it passes through the blade outlet 21, the manual clamping roller 2015, and the tail blade clamping roller 2018 before entering the annular guard plate 2012. At this point, the front end of the tail blade will press against the lotus-shaped gear. The blade is inserted into the tooth groove of the lotus-shaped gear 2017 along the curved surface, driving the lotus-shaped gear 2017 to rotate or being guided at a large angle by the lotus-shaped gear 2017 to be pushed against the annular guard plate 2012. At this time, the blade is easily bent after being subjected to force and moves along the inner wall of the annular guard plate 2012 and the guide roller 2016 to realize the tail blade retraction. Without the guidance of the lotus-shaped gear plate, when the tail blade retracts, the loading plate will not be easy to rotate, the resistance of the blade feeder will be great, and the tail blade retraction function cannot be realized.

[0065] In this technical solution, the cutting cutter straightening roller 2014 includes a forward cutting cutter straightening roller and a reverse cutting cutter straightening roller. The forward cutting cutter straightening roller and the reverse cutting cutter straightening roller are symmetrically arranged on both sides of the tail cutter clamping roller 2018, and the forward cutting cutter straightening roller or the reverse cutting cutter straightening roller can be selected as needed to meet different cutting requirements.

[0066] like Figure 3 As shown, the cutter head box 2 includes a box support 226. A set of pull-out guide rails 227 are respectively provided between the two ends of the box support 226 and the two ends of each layer of the cutter head 201, so that the cutter head can be pulled out to the side. The end of the cutter head 201 located in the pull-out direction is also provided with a handle 228. When loading the rolled material, it is only necessary to pull the handle 228 to pull the cutter head 201 to one side to load the material, which is convenient and quick.

[0067] In some embodiments, a locking pin 229 is provided between each layer of the tool holder 201 and the housing support 226 to limit the tool holder and prevent it from falling out at will. In this technical solution, the tool holder box 2 has ten layers of tool holders 201, which can meet the needs of most bending machines.

[0068] like Figure 9As shown, the die-cutting material storage and feeding device also includes a protective shell 4, which surrounds the main support and serves to prevent dust and protect the internal structure.

[0069] In some embodiments, the upper end of the main support is also provided with multiple lifting rings 5 ​​for transporting the device. The bottom of the main support is also provided with multiple moving rollers 6 and support feet 7. The moving rollers 6 are used for moving the device, and the support feet 7 are used for stable support of the device. The support feet 7 are adjustable support feet, which can adjust the balance support of the device. The lower end of the side of the main support where the cutting blade feeding mechanism is provided is also provided with a connecting fixing block 8 for connecting and fixing with the bending machine to ensure stable cutting blade feeding.

[0070] The present invention also provides a method for feeding rolled material, comprising the following steps:

[0071] S1: Manually load the rolled material into the multi-layer cutting disc 201, and pull the blade end of the rolled material out a certain distance from the cutting outlet;

[0072] S2: Install the multi-layer tool holder 201 into the tool holder box 2 in sequence;

[0073] S3: The lifting mechanism drives the cutter head box 2 to move up and down, so that the cutter outlet of the selected cutter head 201 corresponds to the position of the cutting tool feeding mechanism 3;

[0074] S4: The blade clamping mechanism 303 of the cutting tool feeding mechanism 3 moves towards the blade outlet of the corresponding cutting tool plate 201 in the cutting tool box through the telescopic mechanism 304 until the beginning of the blade of the cutting tool material enters between the feeding drive wheel 305 and the feeding driven wheel 306.

[0075] S5: The feeding driven wheel 306 presses against the feeding driving wheel 305 via the clamping cylinder 308. At the same time, the feeding driving wheel 305 starts to rotate, causing its blade to be pulled out from the blade outlet of the loading disc 201 until it is conveyed into the bending machine, thus completing the feeding of the rolled material.

[0076] S6: When the bending machine needs to select the rolled blade material in other cutting discs, the rolling blade feeding mechanism first sends its current blade back to the cutting disc through the blade clamping mechanism, and then the lifting mechanism lifts and lowers the corresponding position so that the blade outlet of the other selected cutting disc is aligned with the feeding mechanism, and then the feeding operations of steps S4 and S5 are performed.

[0077] The present invention also provides a method for tail blade recovery using a coiled material storage and feeding device, comprising the following steps:

[0078] S1: The blade clamping mechanism of the cutting tool feeding mechanism moves towards the blade outlet of the corresponding blade plate in the cutting tool box through the telescopic mechanism 304 until the tail blade of the cutting tool material retracts to the blade outlet of the corresponding blade plate 201 in the cutting tool box 2.

[0079] S2: The blade tail cutter passes through the blade outlet 21, manual blade clamping roller 2015, and tail cutter clamping roller 2018 in sequence, and enters the annular blade guard plate 2012 until it moves to the front end of the tail cutter and is connected to the lotus-shaped gear 2017.

[0080] S3: The front end of the tail knife is inserted into the tooth groove of the lotus-shaped gear 2017 along the curved surface, and drives the lotus-shaped gear 2017 to rotate or is guided by the lotus-shaped gear 2017 at a large angle to push against the annular guard plate 2012. After the blade is subjected to force, it bends and moves along the inner wall of the annular guard plate 2012 and the guide roller 2016 to realize the recovery of the tail knife.

[0081] The present invention can set up a multi-layer tool holder 201 and can automatically lift and select the corresponding tool holder 201. Moreover, the tool holder 201 can also realize the tail knife recovery function. The blade clamping mechanism 303 can realize automatic feeding, automatic return and automatic recovery of the rolled material, which greatly improves the processing efficiency and reduces the labor intensity of workers.

[0082] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
