[0069] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0070] like Figures 1-14 As shown, the present invention provides a material throwing circulation system, comprising a plurality of material storage mold frames 1 and a material throwing module 2 arranged on one side of the plurality of material storage mold frames 1. The material storage mold frame 1 comprises a material storage frame body 11 and a material ejecting device 12 arranged on the material storage frame body 11. The plurality of material storage frames 11 are arranged in sequence along a first horizontal direction. The top of the material bin of the material storage frame body 11 is provided with an inlet and outlet. The rods extend in the material bin along a second horizontal direction and are placed at the output end of the material ejecting device 12. The material ejecting device 12 can eject the rods along a third vertical direction. The first direction, the second direction and the third direction are perpendicular to each other. The material throwing module 2 comprises a bottom support frame 21, a material throwing device 22 and a clamp The holding device 23 and the material throwing device 22 are adjustably arranged on the bottom support frame 21 along the first direction. One end of the rod is the head end and the other end is the tail end. The clamping device 23 is installed on the material throwing device 22 and is configured to clamp the head end of the rod. When the jacking device 12 lifts the rod to the removal position, the material throwing device 22 can drive the head end of the rod to the material throwing position through the clamping device 23, so that the rod is in the material throwing state. When the rod is in the material throwing state, from the head end to the tail end, the rod is moved out of the hopper in sequence under the action of its own gravity.

[0071] In the present invention, a material throwing module 2 is provided on one side of a plurality of material storage mold frames 1, and the material throwing module 2 cooperates with the lifting device 12 on the material storage mold frame 1, so that when transporting the bar, it is only necessary to lift the bar to the removal position by the lifting device 12, and then the head end of the bar is clamped by the clamping device 23 of the material throwing module 2, and the head end of the bar is moved to the material throwing position by the material throwing device 22 of the material throwing module 2 and then the bar is released, so that the bar can finally be thrown out of the silo from the head end to the tail end in sequence under the action of its own gravity. Compared with the overall lifting and transportation, it effectively reduces the driving force, reduces energy consumption, simplifies the transportation steps, improves the transportation efficiency, reduces the danger of the transportation process, and is suitable for the transportation of single bar.

[0072] In this embodiment, the rod is a long steel bar 100 that is capable of radially swinging. When its head end is moved to the ejection position, its main body remains at the output end of the ejection device 12. When its head end falls under the action of gravity, it pulls the portion connected to the head end out of the silo. The rod is then pulled sequentially from the head end to the tail end until the entire rod is ejected from the silo. In other embodiments, the rod can also be other long, radially swingable metal or non-metallic profiles, such as a slender PVC pipe.

[0073] Specifically, multiple storage racks 11 can store and place the rods respectively. When the materials are divided and circulated, the pushing device 12 can push the rods out of the material bin of the storage rack 11, so that the throwing module 2 can swing and move the rods. The throwing module 2 can transfer the rods between two adjacent material bins. The transfer distance is short, the circulation operation is simple and efficient, time-saving and labor-saving, safe and reliable.

[0074] In this embodiment, three material storage racks 11 are provided, and the bottom support frames 21 are provided on one side of the three material storage mold frames 1 along the second direction.

[0075] Specifically, the lifting device 12 includes a lifting driver 121 and a loading rack 122. The lifting driver 121 is arranged on the storage rack body 11, and the loading rack 122 is arranged at the output end of the lifting driver 121. As the output end of the lifting device 12, it can carry multiple rods.

[0076] More specifically, the ejection device 12 also includes a lifting bracket 123 and a vibration-damping pad 124. The lifting bracket 123 is vertically slidably connected to the storage frame 11 and to the output of the ejection driver 121. The vibration-damping pad 124 is sandwiched between the loading frame 122 and the lifting bracket 123. The vibration-damping pad 124 allows the loading frame 122 to more safely and reliably receive the bars that fall into the silo.

[0077] Specifically, the lifting device 12 also includes a buffer member 125, which is clamped between the material carrier 122 and the lifting support frame 123, and plays a role in buffering the material carrier 122, further improving the safety and reliability of the material carrier 122.

[0078] More specifically, the storage rack body 11 is provided with a vertically extending slideway, and guide wheels 126 are respectively installed on both sides of the lifting support frame 123, and the lifting support frame 123 is slidably set in the slideway through the guide wheels 126.

[0079] More specifically, the ejecting device 12 further comprises a vibration motor 127, which is fixed to the carrier 122. By providing the vibration motor 127, the stacking of the bars is avoided, so that the bars can be laid flat on the carrier 122, which is convenient for the subsequent operation of the material throwing module 2.

[0080] In this embodiment, the lifting drive 121 includes a motor and a lifting screw. The motor is fixed to the storage rack 11, and the lifting screw is rotatably installed on the storage rack 11. The motor drives the vertical lifting screw to rotate around its own axis through a worm gear structure. A rotating sleeve is fixed on the lifting support frame 123 through a fixed block, and the rotating sleeve is screwed to the lifting screw. When the lifting support frame 123 is large in size, two lifting screws are provided. One lifting screw is directly driven by the motor through a worm gear structure. On this basis, a transmission rod is added to the output shaft of the motor. Driven by the motor, the transmission rod drives the other lifting screw through a worm gear structure. The buffer 125 is an existing structure such as a spring and a damper, which will not be repeated here. The vibration motor 127 is arranged at the bottom of the loading rack 122, and one or more are provided according to the size of the loading rack 122.

[0081] In other embodiments, the ejection driver 121 may also be a pneumatic cylinder, an oil cylinder, an electric cylinder, a linear motor, etc., which will not be described in detail here.

[0082] Specifically, the storage die frame 1 also includes a sliding conveying device 13, which includes a slide frame 131 and an opening and closing drive mechanism 132. Among them, the slide frame 131 is arranged on the storage frame body 11, and the top of the slide frame 131 is provided with a sliding surface. The opening and closing drive mechanism 132 can drive the slide frame 131 to move between a closed position and an open position. When the slide frame 131 is in the open position, the rods can be removed from the silo. When the slide frame 131 is in the closed position, the sliding surfaces of multiple slide frames 131 have the same inclination direction, and multiple inlet and outlet ports are respectively closed. Under the action of their own gravity, the rods can slide from one sliding surface to another adjacent sliding surface. The above arrangement allows the material throwing module 2 to only need to throw the rods to move to the adjacent storage frame body 11, and the rods can slide along the sliding surface of the slide frame 131 to a storage frame body 11 farther away under the action of their own gravity.

[0083] More specifically, the slide frame 131 includes a plurality of support shafts 1311 and a plurality of slide plates 1312. The plurality of support shafts 1311 are connected to the plurality of slide plates 1312 in a one-to-one correspondence. The storage frame body 11 is provided with a shaft sleeve, in which the support shafts 1311 are inserted, and a slide surface is provided on the top of the slide plate 1312. This arrangement enables the slide frame 131 to guide and slide larger-sized bars.

[0084] More specifically, the opening and closing drive mechanism 132 includes a swinging member 1321, a linkage rod 1322, and an opening and closing driver 1323. Multiple swinging members 1321 are provided, each corresponding to a plurality of sliding plates 1312. One end of each swinging member 1321 is sleeved onto the support shaft 1311, and the other end is rotatably connected to the linkage rod 1322. The opening and closing driver 1323 is disposed on the storage rack 11 and is configured to drive the rotation of one swinging member 1321. This arrangement enables the opening and closing driver 1323 to synchronously drive the rotation of multiple sliding plates 1312, making it more efficient and reliable.

[0085] In this embodiment, the axis of the support shaft 1311 is parallel to the vertical third direction and is passed through at least two shaft sleeves. Multiple support shafts 1311 are arranged in sequence at intervals along the horizontal second direction. One end of the swing member 1321 is sleeved on the support shaft 1311 and can move along the axis of the support shaft 1311, but cannot rotate around the axis of the support shaft 1311. The other end is rotatably connected to the linkage rod 1322 through a pin shaft. The linkage rod 1322 includes multiple segments, and a segment is provided between two adjacent support shafts 1311. The two ends of each segment are rotatably connected to the two support shafts 1311 respectively, and the rotation axis is parallel to the vertical third direction. The opening and closing driver 1323 is a cylinder, and the cylinder body is rotatably connected to the storage rack body 11 through a support, and the rotation axis is parallel to the vertical third direction. The piston rod of the cylinder extends in the horizontal direction and is rotatably connected to the linkage rod 1322 through a pin shaft.

[0086] Specifically, the sliding conveyor 13 further includes a lifting drive mechanism 133, which can drive the slide frame 131 to move along the third direction. The above arrangement reduces the lifting height of the rod material by the lifting device 12 when guiding the material, so that the slide frame 131 can not only guide the rod material to the storage rack 11 at other positions, but also guide the storage rack 11 where the slide frame 131 is located, so that the height dimensions of multiple storage racks 11 can be consistent.

[0087] More specifically, the lifting drive mechanism 133 includes a lifting drive 1331 and a transmission gear 1332. The lifting drive 1331 is mounted on the storage frame 11 and is capable of driving the transmission gear 1332 to rotate about its own axis. The slide 131 includes a support shaft 1311, which is mounted on the storage frame 11 and has a sleeve. The support shaft 1311 is mounted in the sleeve and has a scalloped gear section. The transmission gear 1332 engages with the scalloped gear section. This arrangement allows the slide 131 to not only rotate in place but also to be raised and lowered.

[0088] In this embodiment, the lifting drive 1331 includes a motor, a base and a rotating shaft. The motor and the base are respectively fixed to the storage rack body 11. The rotating shaft is rotatably installed on the base and connected to the output end of the motor. The transmission gear 1332 is mounted on the rotating shaft, and multiple are provided. A circular rack segment is provided on the support shaft 1311. The multiple transmission gears 1332 and the circular rack segments of the multiple support shafts 1311 are engaged one by one, so that the motor can drive the multiple sliding racks 131 to rise and fall through the rotating shaft.

[0089] In this embodiment, the three storage racks 11 are respectively the first storage rack, the second storage rack and the third storage rack. The second storage rack is arranged between the first storage rack and the third storage rack. With the cooperation of the sliding conveying device 13, the steel bars 100 in the first storage rack can be transported to the second storage rack and the third storage rack, and the steel bars 100 in the second storage rack can be transported to the third storage rack.

[0090] Specifically, the bottom support frame 21 is in an elongated shape and extends along the first direction. A bottom support slide rail extending along the first direction is provided on the bottom support frame 21, and the material throwing device 22 is slidably provided on the bottom support slide rail.

[0091] More specifically, the material-discarding device 22 includes a first support frame 221, a second support frame 222, a first material-discarding driving mechanism 223, and a second material-discarding driving mechanism 224. The first support frame 221 is slidably arranged on the bottom support frame 21 along the first direction, the second support frame 222 is slidably arranged on the first support frame 221 along the third direction, the clamping device 23 is mounted on the second support frame 222, the first material-discarding driving mechanism 223 is arranged on the first support frame 221, and is configured to drive the first support frame 221 to move along the first direction, and the second material-discarding driving mechanism 224 is arranged on the second support frame 222, and is configured to drive the second support frame 222 to move along the third direction. The above-mentioned arrangement enables the material-throwing device 22 to be more flexibly adapted to the multiple storage racks 11 arranged side by side in the first direction, and can perform material transfer operations more efficiently. The rods can be transferred by clamping the clamping device 23, which is more time-saving and efficient. When the rod's own gravity is insufficient or cannot be provided, the second material-throwing drive mechanism 224 drives the clamping device 23 to move down a set distance through the second support frame 222 and then releases the head end of the rod, thereby providing a certain downward throwing force on the rod. From the head end to the tail end, the steel bar 100 is moved under the action of the downward throwing force.

[0092] In this embodiment, the bottom support frame 21 includes a bottom support frame body and two bottom support slide rails arranged on the bottom support frame body. The two bottom support slide rails are parallel to each other and arranged at intervals. The first support frame 221 is slidably arranged on the two bottom support slide rails through a slider. The first support frame 221 includes a first frame body and two first slide rails arranged on the first frame body. The first slide rails extend along a third direction. The second support frame 222 is slidably arranged on the two first slide rails through a slider.

[0093] Specifically, the first material-ejecting driving mechanism 223 includes a first material-ejecting motor 2231, a first material-ejecting gear 2232, and a first material-ejecting rack 2233. The first material-ejecting motor 2231 is fixedly mounted on the first support frame 221, the first material-ejecting gear 2232 is mounted on the output end of the first material-ejecting motor 2231, the first material-ejecting rack 2233 is laid on the bottom support frame 21 and extends along the first direction, and the first material-ejecting gear 2232 is engaged with the first material-ejecting rack 2233. The above arrangement enables the first support frame 221 to move more accurately and stably along the first direction.

[0094] More specifically, the second material-ejection drive mechanism 224 includes a second material-ejection motor 2241, a second material-ejection gear, and a second material-ejection rack 2242. The second material-ejection motor 2241 is fixedly mounted on the second support frame 222, the second material-ejection gear is mounted on the output end of the second material-ejection motor 2241, and the second material-ejection rack 2242 is laid on the first support frame 221 and extends along the third direction. The second material-ejection gear is engaged with the second material-ejection rack 2242. This arrangement enables the second support frame 222 to move more accurately and stably along the third direction.

[0095] More specifically, the material-discharging device 22 further includes two limiting seats 225, which are respectively mounted on the first support frame 221 and spaced apart in the third direction, and the second support frame 222 is limited between the two limiting seats 225. The above arrangement prevents the second support frame 222 from falling off the first support frame 221.

[0096] In this embodiment, the first material-ejecting rack 2233 is laid on the bottom support frame and is located between the two bottom support slide rails. The first material-ejecting motor 2231 is set on the first frame and can drive the first support frame 221 to move along the bottom support slide rail through the first material-ejecting gear 2232 and the first material-ejecting rack 2233. The second material-ejecting rack 2242 is laid on the first frame and is located between the two first slide rails. The second material-ejecting motor 2241 is set on the second support frame 222 and is configured to drive the second support frame 222 to move along the first slide rail.

[0097] Specifically, the clamping device 23 includes a tilting actuator 231, a tilting support frame 232, and a clamping actuator 233. The tilting actuator 231 is mounted on the material-discharging device 22, the tilting support frame 232 is rotationally connected to the material-discharging device 22, and is connected to the output end of the tilting actuator 231. The clamping actuator 233 is mounted on the tilting support frame 232 and is configured to clamp the bar. With this arrangement, the tilting actuator 231 and the tilting support frame 232 cooperate to drive one end of the bar to lift via the clamping actuator 233, thereby facilitating material discharging.

[0098] In this embodiment, the flipping driver 231 is a cylinder, which is rotatably connected to the second support frame 222. The flipping support frame 232 is rotatably connected to the second support frame 222 through a bearing. The rotation axis of the flipping support frame 232 is parallel to the first direction. The clamping driver 233 is a clamping cylinder, pneumatic fingers, etc., which has two clamping jaws, each of which is equipped with a clamping block. Under the drive of the flipping driver 231, the flipping support frame 232 flips up and down, so that the clamping driver 233 can lift the clamped rod, thereby facilitating the throwing of the rod.

[0099] In other embodiments, the flip actuator 231 may also be an oil cylinder, an electric cylinder, etc.

[0100] The material throwing and circulation system of this embodiment can grab, transport and divide the steel bars 100. It has multiple storage racks 11. A vibration motor 127 is installed on the loading rack 122, which has the function of vibration and dispersion. The lifting driver 121 in the lifting device 12 can drive the loading rack 122 to rise and fall. On this basis, the storage rack 11 is equipped with a sliding conveying device 13. The material throwing module 2 can move between multiple storage racks 11, so that steel bars 100 of different diameters can flow between various silos. The clamping device 23 clamps the steel bars 100, and the material throwing module 2 throws the steel bars 100 out of the silo, saving labor and high production efficiency.

[0101] The present invention also provides a material throwing and circulation method, which uses the above-mentioned material throwing and circulation system, including the following steps:

[0102] Step 1: The lifting device 12 in the initial silo lifts the bar to the removal position;

[0103] Step 2: The clamping device 23 clamps the head end of the rod;

[0104] Step 3: The material throwing device 22 drives the head end of the bar to move to the material throwing position through the clamping device 23, so that the bar is in the material throwing state;

[0105] Step 4: The clamping device 23 releases the head end of the rod;

[0106] Step 5: From the beginning to the end, the bars are thrown out of the initial silo in sequence under the action of their own gravity until they fall into the target silo.

[0107] In the material throwing and circulation method of the present invention, a material throwing module 2 is set on one side of multiple storage mold frames 1, and the material throwing module 2 cooperates with the lifting device 12 on the storage mold frame 1, so that when transporting rods, it is only necessary to lift the rods to the removal position by the lifting device 12, and then the head end of the rod is clamped by the clamping device 23 of the material throwing module 2, and the head end of the rod is moved to the material throwing position by the material throwing device 22 of the material throwing module 2 and then the rod is released, so that the rods can finally be thrown out of the silo from the head end to the tail end in sequence under the action of their own gravity. Compared with the overall lifting and transportation, it effectively reduces the driving force, reduces energy consumption, simplifies the transportation steps, improves the transportation efficiency, and reduces the danger of the transportation process. It is suitable for the transportation of single rods.

[0108] Based on the specific structure of the material-stripping and circulation system in this embodiment, the specific steps of the material-stripping and circulation method in this embodiment include:

[0109] S1. The bars are placed on the loading rack 122 in the silo.

[0110] In this step, when the steel bars 100 need to be processed, in order to facilitate taking the steel bars 100 , the steel bars 100 need to be laid flat, the vibration motor 127 works, and the steel bars 100 are laid flat on the loading rack 122 .

[0111] S2. The lifting device 12 in the initial silo lifts the bar to the removal position.

[0112] In this step, the lifting device 12 in one of the storage rack bodies 11 drives the loading rack 122 to extend out of the silo through the inlet and outlet ports.

[0113] Taking the three storage racks 11 as an example, in the first storage rack, the opening and closing driver 1323 of the opening and closing drive mechanism 132 works, driving the swinging member 1321 to move, the swinging member 1321 is slidably assembled on the support shaft 1311, and the sliding plate 1312 is fixed on the support shaft 1311. When the opening and closing driver 1323 is actuated, the sliding plate 1312 is driven to open according to demand through the swinging member 1321.

[0114] After the sliding plate 1312 is opened, the lifting driver 121 of the lifting device 12 works, the lifting support 123 rises, and the loading rack 122 is placed on the lifting support 123, and is protected by the vibration damping pad 124 and the buffer 125. The lifting support 123 rises and drives the loading rack 122 to rise, and the steel bar 100 is placed on the top surface of the loading rack 122, and the steel bar 100 rises to the highest point.

[0115] S3. The clamping device 23 clamps the head end of the bar.

[0116] In this step, the material throwing device 22 drives the clamping device 23 to move along the bottom support frame 21, so that the clamping device 23 is located on one side of the initial material bin, and then the clamping device 23 clamps the head end of the bar.

[0117] S4. The material-throwing device 22 drives the head end of the bar to move to the material-throwing position through the clamping device 23, so that the bar is in a material-throwing state.

[0118] In this step, when the steel bar 100 needs to be transferred and divided for processing, the material rejection module 2 is moved to the side of the first storage rack through program control. Under the drive of the first material rejection drive mechanism 223 and the second material rejection drive mechanism 224, the first support frame 221 and the second support frame 222 move to corresponding positions. The clamping device 23 clamps one end of the steel bar 100, and cooperates with the drive of the first material rejection drive mechanism 223 and the second material rejection drive mechanism 224 to move the head end of the steel bar 100 to the second storage rack.

[0119] S5. The clamping device 23 releases the head end of the rod.

[0120] In this step, the clamping device 23 releases the head end of the steel bar 100 .

[0121] S6. From the head end to the tail end, the bars are thrown out of the initial silo in sequence under the action of their own gravity and / or the downward throwing force of the throwing device 22 until they fall into the target silo.

[0122] In this step, if Figure 13 As shown, if the steel bars 100 in the first storage rack are to be transferred to the second storage rack, the lifting drive mechanism 133 of the sliding conveyor 13 in the second storage rack drives the sliding rack 131 to move vertically, so that the sliding surface on the top of the sliding plate 1312 can smoothly carry the steel bars 100 thrown out from the loading rack 122 in the first storage rack, and the steel bars 100 slide along the sliding surface under the action of their own gravity to the material bin of the second storage rack, and then the opening and closing driver 1323 in the second storage rack is actuated, and the sliding plate 1312 is driven to open through the swinging member 1321, and the steel bars 100 fall onto the loading rack 122 in the second storage rack.

[0123] In this step, if Figure 14 As shown, if the steel bars 100 in the first storage rack body are to be transferred to the third storage rack body, after the sliding surface of the sliding plate body 1312 on the top of the second storage rack body receives the steel bars 100 thrown out from the loading rack 122 in the first storage rack body, the lifting drive mechanism 133 of the sliding conveyor device 13 in the second storage rack body drives the sliding rack 131 to rise vertically, and in the third storage rack body, the lifting drive mechanism 133 of the sliding conveyor device 13 drives the sliding rack 131 to move vertically, and the second storage rack body The sliding surface at the top of the sliding plate 1312 in the material rack body and the sliding surface at the top of the sliding plate 1312 in the third storage rack body are assembled into an inclined plane. Under the action of its own gravity, the steel bar 100 slides from the sliding plate 1312 in the second storage rack body to the sliding plate 1312 in the third storage rack body. Finally, the opening and closing driver 1323 in the third storage rack body is actuated, and the sliding plate 1312 is driven to open through the swinging member 1321, and the steel bar 100 falls onto the loading rack 122 in the third storage rack body.

[0124] In this step, when the self-weight of the steel bar 100 is insufficient or cannot be provided, the second material-throwing drive mechanism 224 drives the clamping device 23 to move down a set distance through the second support frame 222 and then releases the head end of the steel bar 100, so as to provide a certain downward throwing force on the steel bar 100. From the head end to the tail end, the steel bar 100 is moved under the action of the downward throwing force.

[0125] In other embodiments, when there are three or more storage racks 11 , the material throwing and transfer function of the steel bars 100 can be realized by analogy with the above-mentioned material throwing and transfer method.
