Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a material stacking device, which comprises a rack 1, wherein a feeding mechanism 2, a material containing block 3 and a driving mechanism 4 are arranged on the rack 1, the feeding mechanism 2 and the material containing block 3 are arranged in parallel, and a material stacking bin channel 31 is arranged in the material containing block 3 as shown in fig. 10; the driving mechanism 4 is provided with a material moving mechanism 5; the driving mechanism 4 drives the material moving mechanism 5 to reciprocate between the feeding mechanism 2 and the material containing block 3, so as to move the workpiece from the feeding mechanism 2 to the stacking bin passage 31. The stacking bin channel 31 extends in the vertical direction, and the stacking bin channel 31 is used for accommodating workpieces; the cross section shape of the stacking bin channel 31 is the same as that of the workpiece, so that the stacking bin channel 31 is matched with the appearance shape of the workpiece, and the workpiece is prevented from turning over when falling in the stacking bin channel 31.

The workpiece is a special-shaped iron core; after a worker pours a large batch of workpieces into the feeding mechanism 2, the feeding mechanism 2 feeds the workpieces; the driving mechanism 4 drives the material moving mechanism 5 to move, so that workpieces are transferred from the feeding mechanism 2 to the stacking bin channel 31, and the workpieces are stacked and arranged in the stacking bin channel 31 from bottom to top; the whole transferring and stacking process of the workpieces does not need manual participation, and the yield and the production efficiency are improved.

As shown in fig. 1, a controller 100 is disposed on the rack 1, and as shown in fig. 12, the feeding mechanism 2, the driving mechanism 4, and the material moving mechanism 5 are all electrically connected to the controller 100; the switch and the action sequence of the feeding mechanism 2, the driving mechanism 4 and the material moving mechanism 5 are automatically controlled by a program of the controller 100. In one embodiment, controller 100 is implemented with FX3U-32M chips.

As shown in fig. 2, the feeding mechanism 2 includes a circular vibrating screen 21, and the circular vibrating screen 21 is electrically connected to the controller 100; after a worker pours a large batch of workpieces into the circular vibrating screen 21, the circular vibrating screen 21 is started, and the workpieces move towards the discharging opening 210 of the circular vibrating screen 21 along the circular vibrating screen 21; and the workpieces are arranged by themselves in the moving process. The circular vibrating screen 21 is provided with a plurality of material leaking holes 211 near the feed opening 210, and the material leaking holes 211 have the same shape as the reversely placed workpieces and can only accommodate one workpiece to pass through. When the arranged workpieces move towards the feed opening 210, the workpieces placed in the reverse direction along with the vibration of the circular vibrating screen 21 move to the discharge hole 211, and can just leak from the discharge hole 211, so that the workpieces flowing out of the feed opening 210 are all the workpieces arranged in the forward direction, the directions of the stacked workpieces in the stacking bin channel 31 are the same, and the phenomenon of staggered arrangement in the forward direction and the reverse direction is avoided.

According to a specific embodiment, the special-shaped thin sheet iron core is stacked, the cross section of the iron core is wedge-shaped, namely one end of the iron core is narrow, and the other end of the iron core is wide; when the iron cores in large batch are arranged and conveyed by the feeding mechanism 2 in the front direction towards the moving direction of the iron cores on the feeding mechanism 2, the iron cores with narrow front ends and wide rear ends are forward iron cores, and the iron cores with wide front ends and narrow rear ends are reverse iron cores; the shape of the material leakage hole 211 is the same as that of the cross section of the iron core, and the wide end faces forwards and the narrow end faces thickly. When the reverse iron core moves to the material leakage hole 211, the reverse iron core can leak from the material leakage hole 211, and only the forward iron core is ensured to be continuously transmitted forwards.

When workpieces with different colors need to be stacked in a crossed manner, the two feeding mechanisms 2 are symmetrically arranged on the rack 1, and the material containing block 3 is positioned between the two feeding mechanisms 2; the two feeding mechanisms 2 are electrically connected with the controller 100, and the controller 100 controls the material moving mechanism 5 to move the workpieces with different colors to the material stacking bin passage 31 according to the required stacking sequence, so that the workpieces with different colors can be stacked in a crossed manner. According to actual requirements, when workpieces with three or more colors need to be stacked in a crossed manner, the feeding mechanisms 2 are only required to be additionally arranged on the rack 1, each feeding mechanism 2 correspondingly feeds the workpieces with one color, and the controller 100 controls the sequence of transferring the workpieces by the material transferring mechanism 5 to realize the crossed stacking of the workpieces with multiple colors.

As shown in fig. 2, the feeding mechanism 2 further includes a straight vibrating screen 22, the straight vibrating screen 22 is connected to the feeding opening 210, and the workpiece in the circular vibrating screen 21 is conveyed from the feeding opening 210 to the straight vibrating screen 22 and conveyed forward along a straight line. A groove 221 is formed in the straight vibrating screen 22, and the length direction of the groove 221 is the same as the moving direction of the workpiece; the grooves 221 are formed along the moving path of the workpiece to reduce the contact area between the workpiece and the straight vibrating screen 22, and prevent the workpiece coated with the color paint from being adhered to the straight vibrating screen 22. The circular vibrating screen 21 and the straight vibrating screen 22 are electrically connected with the controller 100, and the controller 100 controls the feeding speed of the workpiece by controlling the on-off and vibration speeds of the circular vibrating screen 21 and the straight vibrating screen 22.

As shown in fig. 2, an optical fiber sensor 6 is disposed on the straight vibrating screen 22 near the feed opening 210 of the circular vibrating screen 21, and the optical fiber sensor 6 is electrically connected to the controller 100; whether a workpiece stays on the straight vibrating screen 22 at a position corresponding to the optical fiber sensor 6 all the time is detected through the optical fiber sensor 6, if yes, it is indicated that the workpiece on the straight vibrating screen 22 is too dense, and the controller 100 controls the circular vibrating screen 21 to stop so as to avoid the workpiece from being jammed on the straight vibrating screen 22.

As shown in fig. 3 and 4, a shielding device 7 and a reset mechanism 8 are arranged on the frame 1, and the shielding device 7 is connected with the frame 1 in a sliding manner; the shielding device 7 is located above the discharging port 220 of the feeding mechanism 2, and when the shielding device 7 slides relative to the rack 1, the shielding device 7 can shield the discharging port 220 from above the discharging port 220 or expose the discharging port 220.

The shielding device 7 is located on the moving path of the material moving mechanism 5, that is, in the present invention, the driving force for driving the shielding device 7 to move to expose the discharge port 220 is derived from the material moving mechanism 5, and there is no need to separately set a driving device for the shielding device 7 to drive the material moving mechanism 5 to move, so that the structure of the stacking device is simplified. Initially, the shielding device 7 shields the discharge hole 220; when the material moving mechanism 5 moves to contact with the shielding device 7, the driving mechanism 4 continues to drive the material moving mechanism 5 to move, so that the material moving mechanism 5 pushes the shielding device 7 to move, and the discharge hole 220 is exposed. When the material moving mechanism 5 grabs the workpiece from the material outlet 220 and moves the workpiece to the material containing block 3, the reset mechanism 8 drives the shielding device 7 to reset and shield the material outlet 220 along with the material moving mechanism 5 is far away from the shielding device 7. When the material moving mechanism 5 is separated from the reset mechanism 8, the shielding device 7 shields the discharge hole 220.

As shown in fig. 1, the driving mechanism 4 includes a first driver 41 and a second driver 42 provided on the first driver 41; the first driver 41 drives the second driver 42 to do linear reciprocating motion along a direction parallel to the arrangement direction of the feeding mechanism 2 and the material containing blocks 3, and the second driver 42 is connected with the material moving mechanism 5 and drives the material moving mechanism 5 to move up and down.

Specifically, the first driver 41 drives the second driver 42 to move towards the vertical vibrating screen 22, the material moving mechanism 5 moves towards the shielding device 7 until the material moving mechanism 5 contacts the shielding device 7 and pushes the shielding device 7 to expose the material outlet 220, then the first driver 41 stops, and the material moving mechanism 5 is opposite to the material outlet 220; the second driver 42 drives the material moving mechanism 5 to move downwards and grab/suck the workpiece at the discharge port 220. The second driver 42 drives the material moving mechanism 5 to move upwards, the first driver 41 drives the second driver 42 to move along a straight line towards the material containing block 3, the material moving mechanism 5 is separated from the shielding device 7, and the resetting mechanism 8 drives the shielding device 7 to reset and shield the discharge hole 220; when the material moving mechanism 5 moves to correspond to the material stacking bin channel 31, the first driver 41 stops, and the second driver 42 drives the material moving mechanism 5 to move downwards, so that the workpiece is conveyed into the material stacking bin channel 31. After the stacking of the workpiece in the stacking bin channel 31 is completed, the second driver 42 drives the material moving mechanism 5 to move upwards and separate from the stacking bin channel 31 to wait for the next transfer of the workpiece.

The sliding direction of the shielding device 7 is parallel to the moving direction of the moving mechanism 5 under the driving action of the second driver 42, so as to ensure that the moving mechanism 5 can push the shielding device 7 to expose the discharge hole 220 in the moving process.

As shown in fig. 6, the first driver 41 includes a motor 411, a lead screw 412 connected to a rotating shaft of the motor 411, and a nut 413 sleeved on the lead screw 412, wherein the lead screw 412 is horizontally arranged and parallel to the arrangement direction of the feeding mechanism 2 and the material containing block 3; the second driver 42 is connected to the nut 413 so as to move linearly along the lead screw 412 under the driving of the nut 413. The second driver 42 comprises a linear motor, and the linear motor is respectively connected with the nut 413 and the material moving mechanism 5; the nut 413 drives the linear motor to do linear motion, and the linear motor drives the material moving mechanism 5 to move up and down.

The sliding direction of the shielding device 7 is perpendicular to the groove 221; the sliding direction of the shielding device 7 is parallel to the arrangement direction of the feeding mechanism 2 and the material containing block 3. The reset mechanism 8 comprises a stop block 81 arranged on the frame 1 and a first elastic piece 82 for connecting the stop block 81 with the shielding device 7; the stopper 81 is used for fixedly mounting the first elastic member 82, and ensuring that the elastic expansion direction of the first elastic member 82 is parallel to the sliding direction of the shielding device 7. When the material moving mechanism 5 drives the shielding device 7 to slide, the shielding device 7 slides towards the direction that the straight vibrating screen 22 is far away from the material containing block 3. The first elastic piece 82 is positioned at one end of the shielding device 7 far away from the material containing block 3; when the first elastic element 82 is in a natural state, the shielding device 7 shields the discharge hole 220; when the material moving mechanism 5 contacts the shielding device 7 and continues to move towards the straight vibrating screen 22 away from the material containing block 3, the first elastic member 82 compresses to provide a space for the movement of the shielding device 7 so as to expose the material outlet 220.

The shielding device 7 is used for shielding at least two workpieces simultaneously; as shown in fig. 3 and 4, a notch 9 is formed at one end of the shielding device 7 close to the material containing block 3; the recess 9 is provided for the passage of only one workpiece. As shown in fig. 4, when the shielding device 7 shields the discharging port 220, an arrangement direction of projections of the notch 9 and the discharging port 220 on the same horizontal plane is parallel to a sliding direction of the shielding device 7, that is, the notch 9 and the discharging port 220 are staggered with each other, and the notch 9 is located on one side of the discharging port 220 close to the material containing block 3; when the material moving mechanism 5 drives the shielding device 7 to slide in a direction away from the material containing block 3, the notch 9 also moves in a direction away from the material containing block 3; as shown in fig. 5, when the material moving mechanism 5 corresponds to the material outlet 220, the notch 9 corresponds to the material outlet 220, the first driver 41 stops, and the second driver 42 drives the material moving mechanism 5 to move downward.

The notches 9 are used for exposing the first workpiece in the shielded workpieces along the conveying direction of the workpieces and shielding the second or simultaneously multiple workpieces behind the first workpiece, so that the material moving mechanism 5 can only move one workpiece at a time, and the workpieces are prevented from being adhered and superposed. The straight sieve that shakes 22 is last to be provided with apron 10, apron 10 is located directly over the recess 221, apron 10 with directly shake and have the clearance that holds the work piece between the sieve 22, just the height in clearance can only hold a work piece, thereby guarantees that the work piece gets into can follow the straight line and arrange in proper order after in the clearance, and can not produce the adhesion stack. Further, the cover plate 10 does not cover the discharge hole 220, and the shielding device 7 is arranged adjacent to the cover plate 10.

As shown in fig. 3, the shielding device 7 includes a baffle 71 and a guide post 72, the guide post 72 is vertically disposed, and the baffle 71 is horizontally disposed; the width of the baffle 71 is greater than or equal to 2 times of the width of the workpieces, so that the baffle 71 can simultaneously shield at least two workpieces. The baffle 71 is connected with the guide post 72 and is connected with the frame 1 in a sliding way; the guide post 72 is positioned on one side of the straight vibrating screen 22 far away from the material containing block 3; the guide post 72 is positioned on the moving path of the material moving mechanism 5; when the material moving mechanism 5 contacts with the guide post 72 and continues to move towards the direction of the vertical vibrating screen 22 away from the material containing block 3, the guide post 72 drives the baffle 71 to slide under the driving force of the material moving mechanism 5, so that the notch 9 corresponds to the material outlet 220 and exposes the material outlet 220.

As shown in fig. 11, a material pushing block 11 is arranged in the material stacking bin channel 31, and the cross section of the material pushing block 11 is the same as the cross section of the workpiece; the ejector block 11 supports the workpiece from below, and prevents the workpiece from falling down and falling down when stacked in the stacking bin 31. A third driver is further arranged on the rack 1, and the third driver is electrically connected with the controller 100; part of the third driver is inserted into the stacking bin channel 31 from the lower end opening of the stacking bin channel 31 and is connected with the ejector block 11 to drive the ejector block 11 to move up and down. The third driver comprises a second linear motor; after the material moving mechanism 5 moves one workpiece into the material stacking bin channel 31, the third driver drives the material pushing block 11 to descend by the height of one workpiece, so as to provide a stacking space for the next workpiece to enter the material stacking bin channel 31.

As shown in fig. 7, a limiting clamp 12 is arranged on the machine frame 1, and the limiting clamp 12 includes a first clamping arm 121 and a second clamping arm 122; an accommodating space 200 is formed between the first clamping arm 121 and the second clamping arm 122, and the accommodating space 200 is located above the material stacking channel 31 and is communicated with the material stacking channel 31; the accommodating space 200 is located on the moving path of the material moving mechanism 5, so that the material moving mechanism 5 can pass through the accommodating space 200 into the stacking bin passage 31. When the limiting clamp 12 is opened, the width of the accommodating space 200 is larger than that of the workpiece, and the material moving mechanism 5 can carry the workpiece into the stacking bin channel 31 and leave the workpiece in the stacking bin channel 31 for gradual stacking. When the limiting clamp 12 is closed, the width of the accommodating space 200 is smaller than that of the workpiece, and the first clamping arm 121 and the second clamping arm 122 limit the workpiece from both sides of the material moving mechanism 5 and from above the workpiece, so that when the material moving mechanism 5 moves out from the stacking bin channel 31 through the accommodating space 200, the workpiece can be left in the stacking bin channel 31 without moving out from the stacking bin channel 31 along with the material moving mechanism 5 due to the viscosity of the color paint on the surface of the workpiece.

The first clamping arm 121 and the second clamping arm 122 are symmetrical to each other and are both rotatably connected with the rack 1; the first clamping arm 121 and the second clamping arm 122 are connected through a second elastic piece 13; the second elastic element 13 is located at one side of the rotational connection point of the first clamping arm 121 and the frame 1, which is close to the stacking bin channel 31; as shown in fig. 7, when the second elastic element 13 is in the natural state, the limiting clamp 12 is opened, that is, when no external force acts on the limiting clamp 12, the limiting clamp 12 is in the opened state in the natural state, so as to ensure that the workpiece carried by the material moving mechanism 5 can smoothly pass through the accommodating space 200 and enter the stacking bin passage 31.

Since the first clamping arm 121 and the second clamping arm 122 are symmetrical to each other and form the limiting clamp 12, when the second elastic member 13 is in a natural state, the limiting clamp 12 is opened, that is, one end of the accommodating space 200 is wide, the other end of the accommodating space is narrow, and the wide end of the accommodating space 200 faces the stacking channel 31.

As shown in fig. 7, when the material moving mechanism 5 is inserted into the stacking channel 31 through the accommodating space 200, the inserting pin 14 is inserted into the accommodating space 200 from the narrow end of the accommodating space 200 and respectively supports the first clamping arm 121 and the second clamping arm 122, so that the narrow end of the accommodating space 200 is widened, the wide end of the accommodating space 200 is narrowed, the second elastic member 13 is compressed, and the position of the accommodating space 200 close to the material moving mechanism 5 is narrowed, so that the limiting clamp 12 is closed, the workpiece on the material moving mechanism 5 is limited, and the workpiece is prevented from moving out of the stacking channel 31 along with the material moving mechanism 5.

When the inserting pin 14 is removed from the accommodating space 200, the limiting clamp 12 automatically resets to the open state under the elastic force of the second elastic piece 13.

As shown in fig. 8, pin 14 includes a pin body 141; the pin body 141 is tapered toward one end of the retaining clip 12, that is, the lower end of the pin body 141, so that the lower end of the pin body 141 becomes thicker gradually from bottom to top. The minimum width of the pin body 141 is smaller than that of the accommodating space 200, so that when the limiting clamp 12 is in an open state, the pin body 141 can be inserted into the narrow end of the accommodating space 200; with the downward movement of the material moving mechanism 5, the pin body 141 gradually moves downward in the accommodating space 200, the parts of the pin body 141 contacting the first clamping arm 121 and the second clamping arm 122 become wider and wider, so that the first clamping arm 121 and the second clamping arm 122 are both supported to rotate relative to the rack 1, the position of the accommodating space 200 close to the material stacking bin passage 31 becomes narrower, and the closing of the limiting clamp 12 is realized.

As shown in fig. 8, the pin 14 further includes a third elastic member 142 located above the pin body 141, and the third elastic member 142 connects the pin 14 with the material moving mechanism 5; the third elastic member 142 elastically extends and contracts in a vertical up-down direction. The third elastic member 142 is used for delaying the opening and closing of the position-limiting clamp 12: when the material moving mechanism 5 carries the workpiece to move toward the lower stacking bin channel 31, the pin body 141 firstly enters the accommodating space 200 and supports the first clamping arm 121 and the second clamping arm 122, the material moving mechanism 5 continuously carries the pin body 141 to move downwards and needs to overcome the elastic force of the third elastic member 142 to compress the third elastic member 142, so as to prolong the retention time of the material moving mechanism 5 in the stacking bin channel 31 and ensure that the workpiece can enter the stacking bin channel 31. When the material moving mechanism 5 moves out upwards, the pin body 141 moves upwards, and meanwhile, the third elastic piece 142 gradually recovers elastic deformation, and only when the third elastic piece 142 completely recovers elastic deformation and the pin body 141 is separated from the accommodating space 200, the limiting clamp 12 can be ensured to be reset to an open state; the third elastic member 142 delays the moving process of the pin body 141 from the accommodating space 200, so that the limiting clamp 12 is delayed to be opened when the material moving mechanism 5 moves out of the material stacking channel 31, and a workpiece carried by the material moving mechanism 5 can be kept in the material stacking channel 31 without being adhered to the material moving mechanism 5 to move out of the material stacking channel 31.

As shown in fig. 8, the contact pin 14 further includes a first mounting portion 143 and a first stopper 144 disposed in the first mounting portion 143; the first mounting part 143 is hollow, and both the upper and lower ends of the first mounting part 143 have openings, and the first limiting block 144 blocks the opening at the upper end of the first mounting part 143; the first mounting part 143 is connected with the material moving mechanism 5, and the third elastic member 142 is located in the first mounting part 143 and connected with the lower end of the first limiting block 144; when the third elastic member 142 is in a natural state, one end of the pin body 141 is located in the first mounting portion 143 and connected to the third elastic member 142, and the other end is located outside the first mounting portion 143.

As shown in fig. 7, the material moving mechanism 5 includes a first adapter plate 51 vertically arranged, a second adapter plate 52 horizontally arranged, and a suction nozzle 53, the second adapter plate 52 is connected to a lower end of the first adapter plate 51, and an upper end of the first adapter plate 51 is connected to the linear motor. Both ends of the second adapter plate 52 in the horizontal direction exceed the first adapter plate 51 and are respectively provided with the suction nozzle 53 and the contact pin 14. A certain distance is reserved between the two ends of the second adapter plate 52 parallel to the arrangement direction of the feeding mechanism 2 and the material containing block 3 and the suction nozzle 53, preferably, the suction nozzle 53 is located at the center of the second adapter plate 52; the second adapter plate 52 can contact the shielding device 7 and drive the shielding device 7 to slide; when the second adapter plate 52 contacts the guide post 72, the distance between the suction nozzle 53 and the guide post 72 is greater than or equal to the width of the discharge port 220, so that when the notch 9 corresponds to the discharge port 220, the discharge port 220 is exposed, and the suction nozzle 53 can correspond to the discharge port 220.

The suction nozzle 53 is electrically connected to the controller 100, and the controller 100 controls the suction nozzle 53 to suck or release a workpiece. As shown in fig. 9, the suction nozzle 53 includes a second mounting portion 532 disposed on the second adapter plate 52, and a second stopper 533, a fourth elastic member 534 and a suction nozzle 535 connected in sequence from top to bottom; the second mounting part 532 is of a hollow structure, and the upper end and the lower end of the second mounting part are provided with openings; the second stopper 533 and the fourth elastic member 534 are both located in the second mounting portion 532, when the fourth elastic member 534 is in a natural state, one end of the suction nozzle 535 is located in the second mounting portion 532 and connected to the fourth elastic member 534, and the other end is located outside the second mounting portion 532, so as to suck or release the workpiece. The fourth elastic member 534 provides a buffer effect for the suction nozzle 535, so as to prevent the suction nozzle 535 from lowering too much when sucking a workpiece, and being damaged due to mutual extrusion with the workpiece. When the gap 9 corresponds to the outlet 220, the suction nozzle 535 is located corresponding to the outlet 220. The first elastic member 82, the second elastic member 13, the third elastic member 142 and the fourth elastic member 534 are all springs.

The second actuator 42 is provided with a vacuum generator 531 (shown in fig. 1), and the vacuum generator 531 is connected to the controller 100 and the suction nozzle 535, respectively.

In summary, the invention provides a stacking device, which comprises a rack, wherein a feeding mechanism, a material containing block and a driving mechanism are arranged on the rack, the feeding mechanism and the material containing block are arranged in parallel, and a stacking bin channel extending along the vertical direction is arranged on the material containing block; the driving mechanism is provided with a material moving mechanism, and the driving mechanism drives the material moving mechanism to move so as to transfer the workpiece from the feeding mechanism to the material stacking bin channel. After large batches of workpieces are poured into the feeding mechanism, feeding is carried out by the feeding mechanism; the driving mechanism drives the material moving mechanism to move, so that workpieces are moved from the feeding mechanism to the material stacking bin channel, and the workpieces are stacked and arranged in the material stacking bin channel from bottom to top; the whole transferring and stacking process of the workpieces does not need manual participation, and the yield and the production efficiency are improved.
