Technical Field

[0001] The utility model relates to a storage yard, in particular to a three-dimensional circulating storage bin. Background Art

[0002] During the processing of workpieces, the workpieces need to be placed on a tray, and the tray is transported to a workbench through the transportation of a transfer mechanism for processing; after the processing is completed, the workpiece is transported out of the tray through the transfer mechanism again;

[0003] In this way, the operator cannot timely place the tray on the transfer mechanism at the initial end of the stroke, that is, the time when there is a vacant tray on the workbench is relatively long, and the above operation efficiency is low;

[0004] In summary, how to realize the timely feeding of the tray onto the workbench has become an urgent problem for researchers in this field to solve. Summary of the Invention

[0005] The technical problem to be solved by the utility model is: how to realize the timely feeding of the tray onto the workbench;

[0006] To solve the above technical problem, the technical solution adopted by the utility model is:

[0008] In this solution, frames are provided on both sides of the base. A space for the linear movement of the transfer unit is arranged between the two frames. On the two frames, there are a first rotary mechanism and a second rotary mechanism which are arranged oppositely and driven by a first driving mechanism, and a third rotary mechanism and a fourth rotary mechanism which are arranged oppositely and driven by a second driving mechanism;

[0009] The first rotary mechanism and the second rotary mechanism move synchronously, and drive the strip to rise or fall under the drive of the pallet. Similarly, the third rotary mechanism and the fourth rotary mechanism move synchronously, and drive the strip to rise or fall under the drive of the pallet;

[0010] The switching unit can switch the pallet between the first rotary mechanism, the second rotary mechanism and the third rotary mechanism, the fourth rotary mechanism;

[0011] When the total processing quantity of the workpiece is small, the transfer unit drives the tray to move linearly, places the tray on the workbench, and after processing, the transfer unit transports it to the initial end of the stroke for blanking, and then reloads it onto the transfer unit for the second time;

[0012] When the total processing quantity of the workpiece is large, the tray together with the workpiece is stored in the first rotary mechanism, the second rotary mechanism or the third rotary mechanism, the fourth rotary mechanism;

[0013] When the tray on the workbench is processed, the transfer unit drives the tray on the workbench to move to the initial end of the stroke for blanking and then immediately returns. At the same time, the third rotary mechanism and the fourth rotary mechanism descend, driving another tray to descend, the first rotary mechanism and the second rotary mechanism rise, and the switching unit transports the tray to the empty position of the third rotary mechanism and the fourth rotary mechanism; during the return process of the transfer unit, the tray that descends to a predetermined height on the third rotary mechanism and the fourth rotary mechanism is transported by the transfer unit to the workbench to process the workpiece on the tray; in this way, when the transfer unit moves to the initial end of the stroke, it can blank the tray and then quickly return, and transport the tray on the third rotary mechanism and the fourth rotary mechanism to the workbench, improving the handling efficiency of the tray; in addition, the operator can store a new tray in the empty position of the first rotary mechanism and the second rotary mechanism.

[0014] To illustrate the specific structure of the transfer unit, the present utility model adopts that the transfer unit includes: a transfer seat, which is connected to the base through a linear rail assembly; a transfer rack, which is arranged on the base; a transfer motor, which is arranged on the transfer seat, and a rotating gear meshing with the transfer rack is arranged at the output end thereof; a transfer lifting cylinder, whose cylinder body is fixed on the transfer seat, and a top plate is arranged at the output end thereof; the top plate is connected to the transfer seat through a linear rail assembly;

[0015] The transfer motor starts, which can drive the transfer part to move along the length direction of the base. The top plate can be lifted or lowered relative to the transfer seat through a lifting cylinder. A material tray can be placed on the top plate. When a material tray is placed on the top plate, the material tray can be separated from the pallet through the lifting of the top plate, or the material tray can be placed on the workbench.

[0016] To illustrate the specific structure of the workbench, the present utility model adopts that the workbench includes: two relatively arranged support platforms, on the upper surface of which universal balls are arranged; a rectifying push plate, which is slidably arranged on the top of each of the support platforms; a rectifying cylinder, the cylinder body of which is fixed on the support platform, and the output end of which is fixedly provided with the rectifying push plate; when the transfer part transports the tray to the support platform, the two rectifying cylinders act, driving the two rectifying push plates to move relatively and abut against the side of the tray to rectify the tray.

[0017] In this solution, when the transfer part drives the material tray onto the support platform so that the bottom of the material tray is flush with the top of the universal ball, the transfer part moves forward, places the material tray at the universal ball on the support platform, and then the rectifying cylinder works, moving the two rectifying push plates relatively, pushing the side of the material tray, and placing the material tray at the center of the support platform, which is convenient for positioning the material tray and facilitating the removal of the material tray by the transfer part next time, and preventing the material tray from tilting and overturning during the transfer process.

[0018] To limit the maximum displacement of the material tray, the present utility model adopts that the workbench further includes: a limiting rod, which connects the two support platforms and is adapted to abut against the front side of the tray.

[0019] In this solution, when the material tray abuts against the limiting rod, the material tray moves to the limit state on the support platform, preventing the material tray from tilting on the support platform.

[0020] Since the rotation of the first driving mechanism driving the first rotating mechanism and the second rotating mechanism is the same as the rotation of the second driving mechanism driving the third rotating mechanism and the fourth rotating mechanism, in this solution, only the specific structures of the first driving mechanism, the first rotating mechanism and the second rotating mechanism are described.

[0021] To illustrate the specific structures of the first rotating mechanism and the second rotating mechanism, the present utility model adopts that the first rotating mechanism includes: a first driving shaft, which is rotatably arranged on the frame; a first driven shaft, which is rotatably arranged on the frame and is located below the first driving shaft; first sprockets, two first sprockets are arranged on both the first driven shaft and the first driving shaft; two first chains, which are correspondingly arranged in an up-and-down manner and cooperate with the two first sprockets, and the end parts of the pallet are respectively fixedly connected with the corresponding first chains.

[0022] The second slewing mechanism includes: a second driving shaft rotatably arranged on the frame; a second driven shaft rotatably arranged on the frame and located below the second driving shaft; second sprockets, with two second sprockets arranged on each of the second driven shaft and the second driving shaft; two second chains correspondingly engaged with the second sprockets arranged vertically, and the end portions of the pallet are fixedly connected to the corresponding second chains respectively.

[0023] The first slewing mechanism and the second slewing mechanism have the same structure and are arranged oppositely. Two first sprockets are arranged on the first driving shaft, and two first sprockets are arranged on the first driven shaft. Two first sprockets on the left side of the first driving shaft and the first driven shaft are arranged vertically and connected to a first chain, and two first sprockets on the right side of the first driving shaft and the first driven shaft are arranged vertically and connected to another first chain. The two ends of the pallet are respectively connected to the two first chains. In this way, when the first driving shaft rotates, it drives the pallet to lift and lower; the structure of the second slewing mechanism is the same as that of the first slewing mechanism.

[0024] To illustrate the specific structure of the first driving mechanism, the first driving mechanism of the present utility model includes: a motor fixed on the base; a first rotating shaft rotatably arranged on the frame; a first driving sprocket fixed in the middle of the first rotating shaft and connected to the output end of the motor through a first transmission chain; a second driving sprocket fixed at one end of the first rotating shaft and connected to a third driving sprocket at the end of the first driving shaft through a second transmission chain; a fourth driving sprocket fixed at the other end of the first rotating shaft; a second transmission shaft rotatably arranged on another frame; a fifth driving sprocket fixed at one end of the second transmission shaft and connected to the fourth driving sprocket through a third transmission chain; a third transmission shaft rotatably arranged on the frame where the second transmission shaft is located, and the direction of rotation between it and the second transmission shaft is reversed through a gear set; a sixth driving sprocket fixed at one end of the third transmission shaft; a seventh driving sprocket fixed at the end of the second driving shaft and connected to the sixth driving sprocket through a fourth transmission chain.

[0025] In this solution, when the motor starts, the power is transmitted to the first rotating shaft through the first driving sprocket and the first transmission chain. The power of the first rotating shaft is divided into two paths. One path drives the first driving shaft to rotate through the second driving sprocket, the second transmission chain, and the third transmission chain, that is, drives the first slewing mechanism to rotate and work.

[0026] The other path of power drives the second driving shaft to rotate through the fourth driving sprocket on the first rotating shaft, the third transmission chain, the fifth driving sprocket, the second transmission shaft, the gear set, the third transmission shaft, the sixth driving sprocket, the fourth transmission chain, and the seventh driving sprocket, that is, drives the second slewing mechanism to work.

[0027] In this way, the synchronous operation of the first slewing mechanism and the second slewing mechanism is realized.

[0028] To illustrate the specific structure of the switching part, the switching part of the present utility model includes: a first sliding seat, the bottom sides of which are slidably connected to the top of the corresponding frame through a linear guide assembly; a sliding rack, which is fixed to the top of one of the frames; a sliding motor, which is fixed to the first sliding seat, and the output end of which is provided with a sliding gear that cooperates with the sliding rack; a lifting seat, which is arranged below the first sliding seat; a second lifting cylinder, which is fixed to the first sliding seat, and the extending end of which is fixed with the lifting seat; two oppositely arranged clamping jaws, which are slidably arranged on both sides of the bottom of the lifting seat; a clamping cylinder, the cylinder body of which is fixed to the bottom of the lifting seat, and the output end of which is connected to the corresponding clamping jaw.

[0029] In this solution, when the sliding motor starts, the first sliding seat can move above the first slewing mechanism and the second slewing mechanism or move above the third slewing mechanism and the fourth slewing mechanism. The lifting seat can be lifted and lowered driven by the second lifting cylinder. The two oppositely arranged clamping jaws can move relative to each other along the lifting seat driven by the clamping cylinder. The workpiece tray can be clamped through the relative movement of the clamping jaws, and the workpiece tray can be placed on the two trays or picked up from the two trays through the lifting and lowering movement of the lifting seat.

[0030] The beneficial effects of the present utility model: The present utility model is a three-dimensional circulating storage bin. When the total amount of workpieces to be processed is large, the workpiece tray together with the workpieces is stored in the first slewing mechanism, the second slewing mechanism or the third slewing mechanism, the fourth slewing mechanism. When the workpiece tray on the workbench is completed, the transfer part drives the workpiece tray on the workbench to move to the initial end of the stroke for blanking and then immediately returns. At the same time, the third slewing mechanism and the fourth slewing mechanism descend, driving another workpiece tray to descend, and the first slewing mechanism and the second slewing mechanism rise, and the workpiece tray is transported to the vacant position of the third slewing mechanism and the fourth slewing mechanism through the switching part. During the return process of the transfer part, the workpiece tray that descends to a predetermined height on the third slewing mechanism and the fourth slewing mechanism is transported by the transfer part to the workbench to process the workpieces on the workpiece tray. In this way, when the transfer part moves to the initial end of the stroke, it can blank the workpiece tray and then quickly return, and transport the workpiece tray on the third slewing mechanism and the fourth slewing mechanism to the workbench, improving the handling efficiency of the workpiece tray. In addition, the operator can store a new workpiece tray in the vacant position of the first slewing mechanism and the second slewing mechanism. Description of the Drawings

[0039] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic way, so they only show the components related to the present invention.

[0040] Such as Figure 1As shown in the figure, the utility model is a three-dimensional circulating silo, including: a base 1, on which two opposite frames 2 are arranged; a transfer part 3, which is slidably arranged on the base 1 and is located between the two frames 2; a workbench 4, which is fixedly arranged on the base 1 and is located at the end of the stroke of the transfer part 3; a first rotary mechanism 5, which is arranged on one of the frames 2; a second rotary mechanism 6, which is arranged on the other frame 2 and is arranged opposite to the first rotary mechanism 5; a first driving mechanism 10, which is adapted to drive the first rotary mechanism 5 and the second rotary mechanism 6 to rotate synchronously and in opposite directions; a third rotary mechanism 7, which is arranged on one of the frames 2; a fourth rotary mechanism 8, which is arranged on the other frame 2 and is arranged opposite to the third rotary mechanism 7; a second driving mechanism 11, which is adapted to drive the third rotary mechanism 7 and the fourth rotary mechanism 8 to rotate synchronously and in opposite directions; the first rotary mechanism 5 and the third rotary mechanism 7 on the same frame 2 rotate in opposite directions; a plurality of pallet boards 12, which are fixed on the first rotary mechanism 5, the second rotary mechanism 6, the third rotary mechanism 7, and the fourth rotary mechanism 8, and two relatively arranged pallet boards 12 are used to support both sides of the tray 13; a switching part 14, which is slidably arranged on the tops of the two frames 2, and is adapted to transport the tray supported on the pallet boards 12 of the third rotary mechanism 7 and the fourth rotary mechanism 8 to the pallet boards 12 of the first rotary mechanism 5 and the second rotary mechanism 6, or is adapted to transport the tray 13 supported on the pallet boards 12 of the first rotary mechanism 5 and the second rotary mechanism 6 to the pallet boards 12 of the third rotary mechanism 7 and the fourth rotary mechanism 8;

[0041] In this solution, frames are arranged on both sides of the base. A space for the linear movement of the transfer part is arranged between the two frames. On the two frames, a first rotary mechanism and a second rotary mechanism that are arranged opposite to each other and are driven by a first driving mechanism, and a third rotary mechanism and a fourth rotary mechanism that are arranged opposite to each other and are driven by a second driving mechanism are arranged;

[0042] The first rotary mechanism and the second rotary mechanism move synchronously, and drive the material strip to rise or fall under the drive of the pallet board. Similarly, the third rotary mechanism and the fourth rotary mechanism move synchronously, and drive the material strip to rise or fall under the drive of the pallet board;

[0043] The switching part can switch the tray between the first rotary mechanism, the second rotary mechanism and the third rotary mechanism, the fourth rotary mechanism;

[0044] When the total amount of workpieces to be processed is small, the transfer part drives the tray to move linearly, places the tray on the workbench, and after processing, it is transported to the initial end of the stroke by the transfer part for blanking, and then re-fed to the transfer part;

[0045] When the total amount of workpieces to be processed is large, the tray together with the workpieces is stored in the first rotating mechanism, the second rotating mechanism, the third rotating mechanism or the fourth rotating mechanism;

[0046] When the tray on the workbench is completed, the transfer part drives the tray on the workbench to move to the initial end of the stroke for blanking and then returns immediately. At the same time, the third rotating mechanism and the fourth rotating mechanism descend, driving another tray to descend, and the first rotating mechanism and the second rotating mechanism ascend. And through the switching part, the tray is transported to the empty positions of the third rotating mechanism and the fourth rotating mechanism; during the return process of the transfer part, the tray that descends to a predetermined height on the third rotating mechanism and the fourth rotating mechanism is transported by the transfer part to the workbench to process the workpieces on the tray; in this way, when the transfer part moves to the initial end of the stroke, it can quickly return after blanking the tray, and transport the tray on the third rotating mechanism and the fourth rotating mechanism to the workbench, improving the handling efficiency of the tray; in addition, the operator can store a new tray in the empty positions of the first rotating mechanism and the second rotating mechanism.

[0047] As Figure 2 shown, in order to illustrate the specific structure of the transfer part, the present invention adopts that the transfer part 3 includes: a transfer seat 31, which is connected to the base 1 through a linear rail assembly; a transfer rack 32, which is arranged on the base 1; a transfer motor 33, which is arranged on the transfer seat 31, and a rotating gear meshing with the transfer rack 32 is arranged at the output end thereof; a transfer lifting cylinder 34, whose cylinder body is fixed on the transfer seat 31, and a top plate 35 is arranged at the output end thereof; the top plate 35 is connected to the transfer seat 31 through a linear rail assembly;

[0048] When the transfer motor is started, it can drive the transfer part to move along the length direction of the base. The top plate moves up and down relative to the transfer seat through the lifting cylinder. A tray can be placed on the top plate. When a tray is placed on the top plate, the tray can be separated from the pallet through the lifting of the top plate, or the tray can be placed on the workbench.

[0049] As Figure 3 shown, in order to illustrate the specific structure of the workbench, the present invention adopts that the workbench 4 includes: two relatively arranged support platforms 41, on the upper surface of which universal balls 42 are arranged; a rectifying push plate 43, which is slidably arranged on the top of each support platform 41; a rectifying cylinder 44, whose cylinder body is fixed on the support platform 41, and the rectifying push plate 43 is fixedly arranged at the output end thereof; when the transfer part 3 transports the tray 13 to the support platform 41, the two rectifying cylinders 44 act, driving the two rectifying push plates 43 to move relatively and abut against the side of the tray 13 to rectify the tray 13;

[0050] In this solution, when the transfer unit drives the tray onto the support table so that the bottom of the tray is flush with the top of the universal balls, the transfer unit moves forward, places the tray on the universal balls on the support table, and then the centering cylinder operates to move the two centering push plates relative to each other, pushing the sides of the tray to center the tray on the support table, facilitating the positioning of the tray and facilitating the next removal of the tray by the transfer unit, preventing the tray from tilting or tipping over during transportation.

[0051] As Figure 3 shown, to limit the maximum displacement of the tray, the present utility model adopts that the workbench 4 further includes: a limiting rod 45, which connects the two support tables 41 and is adapted to abut against the front side of the tray 13;

[0052] In this solution, when the tray abuts against the limiting rod, the tray moves to the extreme state on the support table, preventing the tray from tilting on the support table.

[0053] Since the rotation of the first driving mechanism driving the first rotating mechanism and the second rotating mechanism is consistent with the rotation of the second driving mechanism driving the third rotating mechanism and the fourth rotating mechanism, in this solution, only the specific structures of the first driving mechanism, the first rotating mechanism, and the second rotating mechanism are described.

[0054] As Figure 4 、 5 shown, to illustrate the specific structures of the first rotating mechanism and the second rotating mechanism, the present utility model adopts that the first rotating mechanism 5 includes: a first driving shaft 51, which is rotatably arranged on the frame 2; a first driven shaft 52, which is rotatably arranged on the frame 2 and is located below the first driving shaft 51; first sprockets 53, with two first sprockets 53 provided on both the first driven shaft 52 and the first driving shaft 51; two first chains 54, which are correspondingly engaged with the first sprockets 53 arranged up and down, and the end portions of the tray 12 are respectively fixedly connected to the corresponding first chains 54;

[0055] the second rotating mechanism 6 includes: a second driving shaft 61, which is rotatably arranged on the frame 2; a second driven shaft 62, which is rotatably arranged on the frame 2 and is located below the second driving shaft 61; second sprockets 63, with two second sprockets 63 provided on both the second driven shaft 62 and the second driving shaft 61; two second chains 64, which are correspondingly engaged with the second sprockets 64 arranged up and down, and the end portions of the tray 12 are respectively fixedly connected to the corresponding second chains 64;

[0056] The first slewing mechanism and the second slewing mechanism have the same structure and are arranged oppositely. There are two first sprockets provided on the first driving shaft, and two first sprockets are provided on the first driven shaft. On the left side of the first driving shaft and the first driven shaft, two first sprockets are arranged vertically and connected to the first chain. On the right side of the first driving shaft and the first driven shaft, two first sprockets are arranged vertically and connected to another first chain. The two ends of the pallet are respectively connected to the two first chains. In this way, when the first driving shaft rotates, it drives the pallet to move up and down. The structure of the second slewing mechanism is the same as that of the first slewing mechanism.

[0057] As Figure 5 shown, in order to illustrate the specific structure of the first driving mechanism 10, the first driving mechanism 10 of the present invention includes: a motor 101, which is fixed on the base 1; a first rotating shaft 102, which is rotatably arranged on the frame 2; a first transmission sprocket 103, which is fixed in the middle of the first rotating shaft 102 and is connected to the output end of the motor 101 through a first transmission chain 104; a second transmission sprocket 105, which is fixed at one end of the first rotating shaft 102 and is connected to a third transmission sprocket 107 at the end of the first driving shaft 51 through a second transmission chain 106; a fourth transmission sprocket 108, which is fixed at the other end of the first rotating shaft 102; a second transmission shaft 109, which is rotatably arranged on the other frame 2; a fifth transmission sprocket 110, which is fixed at one end of the second transmission shaft 109 and is connected to the fourth transmission sprocket 108 through a third transmission chain 111; a third transmission shaft 112, which is rotatably arranged on the frame 2 where the second transmission shaft 109 is located, and its direction is reversed with the second transmission shaft 109 through a gear set; a sixth transmission sprocket 113, which is fixed at one end of the third transmission shaft 112; a seventh transmission sprocket 114, which is fixed at the end of the second driving shaft 61 and is connected to the sixth transmission sprocket 113 through a fourth transmission chain 115;

[0058] In this solution, when the motor is started, the power is transmitted to the first rotating shaft through the first transmission sprocket and the first transmission sprocket. The power of the first rotating shaft is divided into two paths. One path drives the first driving shaft to rotate through the second transmission sprocket, the second transmission chain, and the third transmission chain, that is, drives the first slewing mechanism to rotate and work;

[0059] The other path of power drives the second driving shaft to rotate through the fourth transmission sprocket of the first rotating shaft, the third transmission chain, the fifth transmission sprocket, the second transmission shaft, the gear set, the third transmission shaft, the sixth transmission sprocket, the fourth transmission chain, and the seventh transmission sprocket, that is, drives the second slewing mechanism to work;

[0060] In this way, the synchronous operation of the first slewing mechanism and the second slewing mechanism is realized.

[0061] As Figure 6As shown, to illustrate the specific structure of the switching part, the switching part 14 of the present utility model includes: a first sliding seat 141, the bottom sides of which are slidably connected to the top of the corresponding frame 2 through a linear guide assembly; a sliding rack 142, which is fixed to the top of one of the frames 2; a sliding motor 143, which is fixed on the first sliding seat 141, and the output end of which is provided with a sliding gear that cooperates with the sliding rack 142; a lifting seat 144, which is arranged below the first sliding seat 141; a second lifting cylinder 145, which is fixed on the first sliding seat 141, and the extending end of which is fixed with the lifting seat 144; two oppositely arranged clamping jaws 146, which are slidably arranged on both sides of the bottom of the lifting seat 144; a clamping cylinder 147, the cylinder body of which is fixed to the bottom of the lifting seat 144, and the output end of which is connected to the corresponding clamping jaw 146;

[0062] In this solution, when the sliding motor is started, the first sliding seat can move above the first rotating mechanism and the second rotating mechanism or move above the third rotating mechanism and the fourth rotating mechanism. The lifting seat can be lifted and lowered under the drive of the second lifting cylinder. The two oppositely arranged clamping jaws can move relatively along the lifting seat under the drive of the clamping cylinder. The material tray can be clamped through the relative movement of the clamping jaws. The material tray can be placed on the two support plates or picked up from the two support plates through the lifting and lowering movement of the lifting seat.
