[0066] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar components or components with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0067] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, it can be a mechanical connection or an electrical connection, it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0069] The technical solution of the present invention is 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, including 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 includes 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 rod material extends in the material bin along a second horizontal direction and is placed at the output end of the material ejecting device 12. The material ejecting device 12 can eject the rod material 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 includes 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 bin in sequence under the action of its own gravity.

[0071] In the present invention, a material throwing module 2 is arranged 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 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 rods is clamped by the clamping device 23 of the material throwing module 2, and the head end of the rods is moved to the material throwing position by the material throwing device 22 of the material throwing module 2 and then the rods are released, so that finally the rods can 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 the 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 rods.

[0072] In this embodiment, the rod is a steel bar 100, which is relatively long and can swing radially. When its head end is moved to the material throwing position, the main body still stays at the output end of the material ejecting device 12. When its head end falls under the action of gravity, it will pull the part connected to the head end out of the silo, and then be pulled from the head end to the tail end in sequence until the whole is thrown out of the silo. In other embodiments, the rod can also be other metal or non-metal profiles that are relatively long and can swing radially, such as a slender PVC pipe.

[0073] Specifically, a plurality of storage racks 11 can store and place the rods respectively. When the materials are divided and circulated, the ejecting device 12 can eject the rods from the silo of the storage rack 11, so that the throwing module 2 can swing and transport the rods. The throwing module 2 can transfer the rods between two adjacent silos. The transportation 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 rack bodies 11 are provided, and the bottom support frame 21 is 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 material 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 material ejection device 12 further includes a lifting support frame 123 and a vibration-damping pad 124. The lifting support frame 123 is slidably connected to the material storage frame 11 in the vertical direction and is connected to the output end of the material ejection driver 121, and the vibration-damping pad 124 is sandwiched between the material carrier 122 and the lifting support frame 123. By providing the vibration-damping pad 124, the material carrier 122 can more safely and reliably receive the rods falling into the material bin.

[0077] Specifically, the blanking device 12 further includes a buffer member 125. The buffer member 125 is clamped between the loading rack 122 and the lifting support frame 123, playing a role in buffering the loading rack 122 and further improving the safety and reliability of the loading rack 122.

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

[0079] More specifically, the blanking device 12 further includes a vibration motor 127. The vibration motor 127 is fixedly installed on the loading rack 122. By setting the vibration motor 127, the stacking of the bars is avoided, enabling the bars to be laid flat on the loading rack 122, which is convenient for the subsequent operation of the blanking module 2.

[0080] In this embodiment, the blanking driver 121 includes a motor and a jacking screw. The motor is fixedly installed on the storage rack body 11, and the jacking screw is rotatably installed on the storage rack body 11. The motor drives the vertical jacking screw to rotate around its own axis through a worm and worm gear structure. A rotating sleeve is fixedly installed on the lifting support frame 123 through a fixed block, and the rotating sleeve is screwed onto the jacking screw. When the size of the lifting support frame 123 is relatively large, two jacking screws are provided. One jacking screw is directly driven by the motor through a worm and worm gear structure. On this basis, a transmission rod is installed on the output shaft of the motor. Driven by the motor, the transmission rod drives the other jacking screw through a worm and worm gear structure. The buffer member 125 is a conventional structure such as a spring or a damper, which will not be elaborated 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 blanking driver 121 can also be a cylinder, an oil cylinder, an electric cylinder, a linear motor, etc., which will not be elaborated here.

[0082] Specifically, the storage die rack 1 further includes a sliding conveying device 13. The sliding conveying device 13 includes a sliding rack 131 and an opening and closing driving mechanism 132. Among them, the sliding rack 131 is arranged on the storage rack body 11, and the top of the sliding rack 131 is provided with a sliding surface. The opening and closing driving mechanism 132 can drive the sliding rack 131 to move between a closed position and an open position. When the sliding rack 131 is in the open position, the bars can be removed from the storage bin. When the sliding rack 131 is in the closed position, the inclination directions of the sliding surfaces of multiple sliding racks 131 are the same, respectively closing multiple feeding and discharging ports. Under the action of its own gravity, the bars can slide from one sliding surface to an adjacent another sliding surface. The above setting enables the blanking module 2 to only shake the bars to move to the adjacent storage rack body 11, and the bars can slide along the sliding surface of the sliding rack 131 to a farther storage rack body 11 under the action of their own gravity.

[0083] More specifically, the sliding material rack 131 includes a plurality of support shafts 1311 and a plurality of sliding material plates 1312. The plurality of support shafts 1311 are correspondingly connected to the plurality of sliding material plates 1312 one by one. The material storage rack body 11 is provided with bushings, and the support shafts 1311 are inserted into the bushings. The sliding surface is arranged at the top of the sliding material plates 1312. With the above arrangement, the sliding material rack 131 can guide and slide bars with larger sizes.

[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. Among them, a plurality of swinging members 1321 are provided, and the plurality of swinging members 1321 correspond to the plurality of sliding material plates 1312 one by one. One end of the swinging member 1321 is sleeved on the support shaft 1311, and the other end of the swinging member 1321 is rotatably connected to the linkage rod 1322. The opening and closing driver 1323 is arranged on the material storage rack body 11 and is configured to drive one swinging member 1321 to rotate. With the above arrangement, the opening and closing driver 1323 can synchronously drive the plurality of sliding material plates 1312 to rotate, which is more efficient and reliable.

[0085] In this embodiment, the axis of the support shaft 1311 is parallel to the vertical third direction and is inserted into at least two bushings. The plurality of support shafts 1311 are sequentially arranged at intervals along the horizontal second direction. One end of the swinging 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 a plurality of segments. One segment is arranged between two adjacent support shafts 1311. Both ends of each segment are respectively rotatably connected to the two support shafts 1311, and the rotation axis is parallel to the vertical third direction. The opening and closing driver 1323 is a cylinder. The cylinder body of the cylinder is rotatably connected to the material 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 and conveying device 13 further includes a lifting drive mechanism 133, and the lifting drive mechanism 133 can drive the sliding material rack 131 to move along the third direction. With the above arrangement, during material guiding, the lifting height of the material pushing device 12 for the bar is reduced, so that the sliding material rack 131 can not only guide the bar to the material storage rack body 11 at other positions, but also guide it to the material storage rack body 11 where it is located, making the height dimensions of the plurality of material storage rack bodies 11 consistent.

[0087] More specifically, the lifting drive mechanism 133 includes a lifting driver 1331 and a transmission gear 1332. Among them, the lifting driver 1331 is arranged on the storage rack body 11. The lifting driver 1331 can drive the transmission gear 1332 to rotate around its own axis. The sliding rack 131 includes a support shaft rod 1311. The storage rack body 11 is provided with a bushing. The support shaft rod 1311 is inserted into the bushing. The support shaft rod 1311 is provided with a circular rack section, and the transmission gear 1332 meshes with the circular rack section. With the above settings, the sliding rack 131 can not only rotate in place but also move up and down.

[0088] In this embodiment, the lifting driver 1331 includes a motor, a pedestal, and a rotating shaft rod. The motor and the pedestal are respectively fixed on the storage rack body 11. The rotating shaft rod is rotatably installed on the pedestal and connected to the output end of the motor. The transmission gears 1332 are sleeved on the rotating shaft rod and there are multiple of them. The support shaft rod 1311 is provided with a circular rack section. The multiple transmission gears 1332 mesh with the circular rack sections of the multiple support shaft rods 1311 one by one, so that the motor can drive multiple sliding racks 131 to lift through the rotating shaft rod.

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

[0090] Specifically, the bottom support frame 21 is long and extends along the first direction. A bottom support slide rail extending along the first direction is arranged thereon. The material throwing device 22 is slidably arranged on the bottom support slide rail.

[0091] More specifically, the material throwing device 22 includes a first support frame 221, a second support frame 222, a first material throwing driving mechanism 223, and a second material throwing driving mechanism 224. Among them, the first support frame 221 is slidably arranged on the bottom support frame 21 along a first direction, the second support frame 222 is slidably arranged on the first support frame 221 along a third direction, the clamping device 23 is installed on the second support frame 222, the first material throwing 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 throwing 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 settings enable the material throwing device 22 to more flexibly adapt to a plurality of storage rack bodies 11 arranged side by side in the first direction, and can more efficiently perform the material transfer operation. The bars are transported by the clamping of the clamping device 23, which is more time-saving and efficient. And when the self-gravity of the bars is insufficient or unavailable, the second material throwing driving mechanism 224 drives the clamping device 23 to move downward by a set distance through the second support frame 222 and then releases the head end of the bars, so as to provide a certain downward throwing force to the bars. From the head end to the tail end, the steel bars 100 are transported 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 sliders. 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 the third direction, and the second support frame 222 is slidably arranged on the two first slide rails through sliders.

[0093] Specifically, the first material throwing driving mechanism 223 includes a first material throwing motor 2231, a first material throwing gear 2232, and a first material throwing rack 2233. Among them, the first material throwing motor 2231 is fixedly installed on the first support frame 221, the first material throwing gear 2232 is installed on the output end of the first material throwing motor 2231, the first material throwing rack 2233 is laid on the bottom support frame 21 and extends along the first direction, and the first material throwing gear 2232 meshes with the first material throwing rack 2233. The above settings enable the first support frame 221 to move more precisely and stably along the first direction.

[0094] More specifically, the second material throwing driving mechanism 224 includes a second material throwing motor 2241, a second material throwing gear, and a second material throwing rack 2242. Among them, the second material throwing motor 2241 is fixedly installed on the second support frame 222, the second material throwing gear is installed on the output end of the second material throwing motor 2241, the second material throwing rack 2242 is laid on the first support frame 221 and extends along the third direction, and the second material throwing gear meshes with the second material throwing rack 2242. The above settings enable the second support frame 222 to move more precisely and stably along the third direction.

[0095] More specifically, the material throwing device 22 further includes two limit seats 225, which are respectively installed on the first support frame 221 and are spaced in the third direction, and the second support frame 222 is limited between the two limit seats 225. With the above arrangement, the second support frame 222 is prevented from disengaging from the first support frame 221.

[0096] In this embodiment, the first material throwing rack 2233 is laid on the bottom support frame body and is located between the two bottom support slide rails.

Among them, the flipping driver 231 is installed on the material throwing device 22, the flipping support frame 232 is rotatably connected to the material throwing device 22 and is connected to the output end of the flipping driver 231, and the clamping driver 233 is installed on the flipping support frame 232 and is configured to clamp the bar. With the above arrangement, the flipping driver 231 and the flipping support frame 232 cooperate to be able to drive one end of the bar to lift through the clamping driver 233, thus making it more convenient for material throwing.

[0098] In this embodiment, the flipping driver 231 is a cylinder and is rotatably connected to the second support frame 222.

The clamping driver 233 is a clamping oil cylinder, a pneumatic finger, etc., and has two clamping jaws, and a clamping block is installed on each clamping jaw. Driven by the flipping driver 231, the flipping support frame 232 flips up and down, so that the clamping driver 233 can lift the clamped bar, thus facilitating the material throwing of the bar.

[0099] In other embodiments, the flipping driver 231 can also be an oil cylinder, an electric cylinder, etc.

[0100] The material throwing and circulation system of the present embodiment can grab, transport and divide the steel bars 100, and 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 material pushing 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 the 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, which saves labor and has high production efficiency.

[0101] The present invention also provides a material throwing and circulation method, using the above-mentioned material throwing and circulation system, comprising 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 rod to move to the material throwing position through the clamping device 23, so that the rod is in a 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 bin in sequence under the action of their own gravity until they fall into the target bin.

[0107] In the material throwing and circulation method of the present invention, a material throwing module 2 is arranged 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 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 rods is clamped by the clamping device 23 of the material throwing module 2, and the head end of the rods is moved to the material throwing position by the material throwing device 22 of the material throwing module 2 and then the rods are released, so that finally the rods can 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 the 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 rods.

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

[0109] S1. The rods 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 the taking of 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, a material pushing device 12 in a material storage rack body 11 drives the material carrier 122 to extend out of the material bin through the material inlet and outlet.

[0113] Taking three material storage racks 11 as an example, in the first material 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 supporting shaft 1311, and the sliding plate 1312 is fixed on the supporting shaft 1311. When the opening and closing driver 1323 is actuated, the sliding plate 1312 is driven to open as needed through the swinging member 1321.

[0114] After the sliding plate 1312 is opened, the material pushing driver 121 of the material pushing device 12 starts working, the lifting support frame 123 rises, and the loading rack 122 is placed on the lifting support frame 123, and is protected by the vibration-damping pad 124 and the buffer member 125. The lifting support frame 123 rises to drive 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 rod.

[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 at one side of the initial material bin, and then the clamping device 23 clamps the head end of the rod.

[0117] S4, the material throwing device 22 drives the head end of the rod to move to the material throwing position through the clamping device 23, so that the rod 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, and 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, and 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 successively ejected from the initial bins under the action of their own gravity and / or the downward ejection force of the ejection device 22 until they fall into the target bin.

[0122] In this step, as Figure 13 shown, if it is desired to transfer the steel bars 100 in the first storage rack to the second storage rack, then in the second storage rack, the lifting drive mechanism 133 of the sliding conveyor device 13 drives the sliding rack 131 to move vertically, so that the sliding surface at the top of the sliding plate body 1312 can smoothly carry the steel bars 100 ejected from the loading rack 122 in the first storage rack. The steel bars 100 slide along the sliding surface under the action of their own gravity and fall into the bin of the second storage rack. Then, the opening and closing driver 1323 in the second storage rack acts, and drives the sliding plate body 1312 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, as Figure 14 shown, if it is desired to transfer the steel bars 100 in the first storage rack to the third storage rack, then after the sliding surface at the top of the sliding plate body 1312 in the second storage rack receives the steel bars 100 ejected from the loading rack 122 in the first storage rack, the lifting drive mechanism 133 of the sliding conveyor device 13 in the second storage rack drives the sliding rack 131 to move vertically upward. In the third storage rack, the lifting drive mechanism 133 of the sliding conveyor device 13 drives the sliding rack 131 to move vertically. The sliding surfaces at the tops of the sliding plate bodies 1312 in the second storage rack and the third storage rack are assembled into an inclined plane. The steel bars 100 slide from the sliding plate body 1312 in the second storage rack to the sliding plate body 1312 in the third storage rack under the action of their own gravity. Finally, the opening and closing driver 1323 in the third storage rack acts, and drives the sliding plate body 1312 to open through the swinging member 1321, and the steel bars 100 fall onto the loading rack 122 in the third storage rack.

[0124] In this step, when the self-gravity of the steel bars 100 is insufficient or unavailable, the second ejection drive mechanism 224 drives the clamping device 23 to move downward a set distance through the second support frame 222 and then releases the head end of the steel bars 100, so as to provide a certain downward ejection force to the steel bars 100. From the head end to the tail end, the steel bars 100 are transported under the action of the downward ejection force.

[0125] In other embodiments, when there are more than three storage racks 11, by analogy with the above-described ejection and transfer method, the ejection and transfer function of the steel bars 100 is realized.

For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description.
