Currently, as enterprises tend to develop automation and intelligence, more and more enterprises are replacing manual production with automation equipment and intelligent factories. In the production process of products, the packaged products need to be stacked for convenient transportation and storage. Because the models of products are different and the sizes are different, the efficiency is low due to the traditional manual stacking mode, and the requirement of high yield of enterprises is difficult to meet.

In order to solve the problems of the prior art, the present embodiment provides a product palletizing device, as shown in fig. 1, the product palletizing device in the present embodiment includes a rotary transition mechanism 10, a combining mechanism 20, a pushing mechanism 30, a stacking mechanism 40, and a cardboard distributing mechanism 50. Arrows in fig. 1 indicate the moving direction of products to be palletized, and the rotary transition mechanism 10 is in butt joint with the product assembly line and is used for sequentially receiving the products to be palletized on the product assembly line, and when the products need to be palletized, the products on the product assembly line first enter the rotary transition mechanism 10 for buffering. The parallel mechanism 20 is connected with the rotary transition mechanism 10 and is used for receiving a preset number of products to be stacked. The parallel mechanism 20 in this embodiment can determine the number of products required for stacking each layer according to different products, so that the parallel mechanism 20 receives a preset number of products to be palletized according to the requirement and performs a tape-breaking process, so as to prevent the products from scattering, and the preset number is the number of each layer. When the number of the products to be stacked in the parallel mechanism 20 reaches the preset number, all the products to be stacked are conveyed to the pushing mechanism 30, and then the products to be stacked are pushed to the preset material taking position through the pushing mechanism 30. Then, after the product to be palletized after the tape-punching process enters the material-taking position, the stacking mechanism 40 located right above the pusher mechanism 30 moves the product to be palletized on the material-taking position to a preset clamping plate 520 (as shown in fig. 1), the clamping plate is placed at a specified position in advance through the clamping plate material-distributing mechanism 50, and the stacking work of the layer of palletized product is realized after the product to be palletized moves to the preset clamping plate. Therefore, the product stacking device disclosed by the invention can automatically stack products, and can perform banding processing every time one layer of products is stacked, so that the products are effectively prevented from scattering. The whole implementation process of the product stacking device is automatic, manual loading and conveying processes are not needed, labor cost is saved, and product stacking efficiency is improved.

Specifically, as shown in fig. 2, the rotary transition device in the present embodiment includes a conveyor belt 110 and a rotary motion mechanism 140. The conveying belt 110 is butted with the product assembly line, and guard rails 120 are further arranged on two sides of the conveying belt 110, so that after products to be palletized on the product assembly line enter the conveying belt 110, the guard rails 120 on two sides can prevent the products to be palletized from inclining. An in-place detection switch 130 is further disposed on the rotary transition device, and when the in-place detection switch 130 detects that the product to be palletized is transported in place, the conveyor belt 110 is controlled to stop operating. Simultaneously, the rotatory transition device of this embodiment still can further judge that the product of waiting to pile up neatly of transporting comes belongs to first product of waiting to pile up neatly, if the first product of waiting to pile up neatly, will through the rotary motion mechanism 140 in this rotatory transition device with first product of waiting to pile up neatly rotates 180, and two products in the product of waiting to pile up neatly of each layer need be dorsad, prevent the damage when the product scatters.

In the present embodiment, as shown in fig. 3, the rotary motion mechanism 140 includes a rotary gear reduction motor 141 and an external gear 142 connected to the rotary gear reduction motor 141, the external gear 142 is provided with a rotary support plate 143, the rotary support plate 143 is located below the conveyor belt 110, the product to be palletized is located above the rotary support plate 143, and when the product to be palletized needs to be rotated, the conveyor belt 110 on the rotary support plate 143 can be smoothly rotated by 180 ° by the meshing action between the gears. When the rotation-to-position switch 144 detects that the product to be palletized is rotated to the position, the rotary gear motor can be controlled to stop working, and at this time, the conveying belt 110 continues to work to convey the product to be palletized into the parallel machine mechanism 20. After the products to be palletized completely flow into the parallel machine mechanism 20, the conveying belt 110 returns to the initial state to wait for the next product to be palletized.

In particular, as shown in fig. 4, the arrows in fig. 4 indicate the movement method of the products to be palletized. The doubling mechanism 20 in this embodiment includes a roller conveying mechanism 210 and a push plate mechanism 220, the roller conveying mechanism 210 is abutted with the conveying belt 110 in the rotary transition mechanism 10, the push plate mechanism 220 is disposed on both sides of the roller conveying mechanism 210, and the push plate mechanism 220 is used for controlling a preset number of products to be palletized to enter the roller conveying mechanism 210. In specific implementation, as shown in fig. 5, the push plate mechanism 220 in this embodiment includes a first push plate 221 and the second push plate 222, and the first push plate 221 and the second push plate 222 are disposed opposite to each other. In the initial state, the first push plate 221 and the second push plate 222 are fully opened, and the blocking jacking cylinder 230 in the mechanism 20 starts to act, so as to prevent the products to be palletized from flowing downwards. Then, the push plate motor 240 drives the screw rod 250 to drive the push plate to move, so that the distance between the first push plate 221 and the second push plate 222 is the width of the product to be palletized, and the product to be palletized can smoothly flow into the space. After the products to be stacked flow in, the first pushing plate 221 and the second pushing plate 222 move simultaneously, the products to be stacked are moved to the storage position, the moving distance is set by a program, the pushing plate motor 240 drives the screw 250 to complete the movement, after the products are moved to the specified position, the first pushing plate 221 returns to the initial state, the second pushing plate 222 is not moved, when the next product to be stacked flows into the parallel mechanism 20, the first pushing plate 221 and the second pushing plate 222 move simultaneously again, meanwhile, the moving distance of the first pushing plate 221 and the second pushing plate 222 is approximately equal to the width of the product, the process is repeated until the number of the stored products in the parallel mechanism 20 reaches the set value of each layer, and the ordered products flow into the push mechanism 30. When all the products to be palletized completely flow into the parallel mechanism 20, the inductive switch arranged in the parallel mechanism 20 can detect the products to be palletized, and the roller conveying mechanism 210 stops operating. When the roller conveying mechanism 210 stops operating, the first push plate 221 moves towards the second push plate 222, the second push plate 222 moves backwards, the products which have flowed into the combining mechanism 20 are orderly placed by the thrust of the first push plate 221, and the products are subjected to a banding process by the banding mechanism 60 (shown in fig. 1) so as to prevent the products from scattering.

In one implementation, the parallel mechanism 20 in this embodiment is provided with brushes 260, the brushes 260 are disposed on two sides of the roller conveying mechanism 210, and the brushes 260 can provide a certain friction force to prevent the product from tilting when the product to be palletized moves on the roller conveying mechanism 210.

Further, the parallel operation mechanism 20 in this embodiment also counts the products to be palletized entering the parallel operation mechanism 20 through the inductive switch, and if the number of the products to be palletized reaches a preset value, it indicates that all the products to be palletized of the layer have completely flowed into the parallel operation mechanism 20, at this time, the blocking cylinder descends, and at this time, the products to be palletized enter the pusher mechanism 30. As shown in fig. 6, arrows in fig. 6 indicate a moving direction of products to be palletized, the pushing mechanism 30 in this embodiment mainly functions to center and position the products to be palletized, which have been punched, below the stacking mechanism 40, the products, which have been punched, flow into the pushing mechanism 30 through the conveying roller 310, trigger a photoelectric switch at the rear end of the pushing mechanism 30, the conveying roller 310 of the pushing mechanism 30 stops moving, the pushing mechanism 320 pushes the sorted products to be palletized to a proper position according to set parameters, at this time, the products to be palletized are located at a preset material taking position, and wait for the stacking mechanism 40 to take materials. When the stacking mechanism 40 takes materials, as shown in fig. 7, the jacking cylinder 330 in the pushing mechanism 30 drives the jacking counterweight rod 340 to ascend, so that the product to be palletized is separated from the conveying roller 310 of the pushing mechanism 30, and the stacking mechanism 40 can take materials conveniently.

As shown in fig. 8, the stacking mechanism 40 in the present embodiment includes: a lifting motion mechanism 410, a clamping mechanism 420, and a horizontal motion mechanism 430. The clamping and holding mechanism 420 is connected with the lifting motion mechanism 410, the clamping and holding mechanism 420 descends to the material placing position 530 through the lifting power device and clamps and holds the products to be stacked, and the horizontal motion mechanism 430 is connected with the clamping and holding mechanism 420 and used for driving the clamping and holding mechanism 420 to move to the clamping plate. Specifically, the lifting mechanism 410 adopts a frequency converter speed regulating motor, and is structurally provided with a balancing weight 440, so that when the product to be palletized rises, the load of the product on the motor is reduced, and the rising is more stable, and the lifting mechanism 410 adopts roller guide and guides on the Z axis. And the clamping mechanism 420 is fixed with the driving wheel of the lifting movement mechanism 410 through a chain. As shown in fig. 9, the clipping mechanism 420 includes a left clipping claw 421 and a right clipping claw 421, and the bottoms of the left clipping claw 421 and the right clipping claw 421 are both arranged in a right-angled edge form and have a certain width. The power of the clamping mechanism 420 is controlled by a servo motor, the transmission unit adopts a positive and negative tooth lead screw, and the guide is provided with a slide rail slide block. When a product to be palletized flows into the clamp to take a material and is driven by the jacking cylinder 330 to jack the jacking sinking weight rod 340, the clamping and holding mechanism 420 descends to a material taking position through the lifting motion mechanism 410, the left clamping and holding claw 421 and the right clamping and holding claw 421 move oppositely through the action of the clamping and holding motor, and the clamping claw with a right-angle side with a certain width clamps and holds the product to be palletized to reach a designated position. Then, the horizontal movement mechanism 430 moves to the stacking position (i.e. the material placing position 530 of the clamping plate), then the whole layer of products to be palletized is moved to the position above the material placing position 530, and then the products are descended to the designated height (which layer is placed specifically) through the lifting movement mechanism 410, at this time, the clamping mechanism 420 is loosened, the products are placed on the clamping plate due to gravity, and the operations are repeated as above, and finally the stacking work of the whole plate products is completed. After the stacking action is completed, the whole plate product is taken away by the next process, and the equipment is circulated.

The horizontal movement mechanism 430 in this embodiment uses a horizontal guide rack and a guide wheel, the horizontal movement mechanism 430 can drive the clamping mechanism 420 to be stable and safe, the moving position is controlled by a program, and when the stacking position is approached, the movement mechanism has a speed reduction function, so that the products to be stacked are accurately placed at the stacking position.

Since the stack of products to be palletized is placed on the pallet in this embodiment, the pallet is pre-set for spacing the products from layer to layer. The cardboard is realized through cardboard feed mechanism 50, and this cardboard feed mechanism 50's main function is with the separation of the good cardboard of manual work, and has the rotation function when having put the orderly pile up neatly product of treating of a certain layer to the pile up neatly product of next floor can have the dislocation with the pile up neatly product of last floor. Specifically, as shown in fig. 10, the arrow in fig. 10 indicates the moving direction of the chucking plate 520. The card separating mechanism 50 in this embodiment transports the cards 520 to the stacking position (i.e., the discharge position 530 of the card separating mechanism 50) via the buffer rollers. In particular implementations, a large number of card stacks are manually placed at the card 520 location. If the buffer roller 560 has no card board 520, the first board dividing mechanism 540 and the second board dividing mechanism 550 act to separate the card board 520, so as to realize the function of delivering the card board 520, and meanwhile, the card board pushing mechanism 510 is arranged on the back side, so that the card board centrally flows into the buffer roller 560. When the discharge position 530 detects no cardboard 520, the action of buffer roller 560, cardboard 520 flows into the material feeding position of this cardboard feed mechanism 50, the end of discharge position 530 is equipped with detection switch and flange, after detection switch detects cardboard 520, cardboard 520 stops the action, wait until stacking mechanism 40 will treat the pile up neatly product and prevent back on cardboard 520, it rotates according to the technology demand to drive swivel bearing 532 through the motor at discharge position 530, realize piling up the pile up neatly mode of dislocation between the product layer.

In the present embodiment, the plate separating mechanism (i.e. the first plate separating mechanism 540 or the second plate separating mechanism 550) in the clamping plate material separating mechanism 50 is provided with a vertical cylinder 541 and a horizontal cylinder 542 as shown in fig. 11, the vertical cylinder 541 is used for adjusting the height of the clamping jaw (used for clamping off the clamping plate 520), and the horizontal cylinder 542 is used for forking. The head of the vertical cylinder 541 is provided with a fork plate mounting rack 544, and the position of the vertical cylinder 541 is judged through a magnetic induction switch on the vertical cylinder 541. The fork mount 544 is fixed with a slide block that is vertically guided by vertical guide rails 546. The horizontal guide rails 547 are fixed to the fork mount 544. The fork claws 543 are fixed to the horizontal guide rail 547, and the function of the fork catch 520 is achieved by the operation of the horizontal cylinder 542, and the magnetic induction switches on the horizontal cylinder 542 determine the position of the gripping jaws. The specific action flow is as follows: in the initial state, the vertical cylinder 541 and the horizontal cylinder 542 are both in an action state, namely, the clamping jaws are at a low position and the clamping jaws avoid a loading position of the clamping plate. The manual work is placed cardboard 520 the back, horizontal cylinder 542 moves, drive the clamping jaw and stretch into between the bottommost cardboard 520 of cardboard position and the gap of penultimate cardboard 520, horizontal cylinder 542's the switch that targets in place detects the back action that targets in place, give perpendicular cylinder 541 signal, perpendicular cylinder 541 drives fork board mounting bracket 544 and wholly rises, make bottommost cardboard break away from with remaining cardboard 410, after target in place on perpendicular cylinder 541, give the cylinder motor signal of cardboard station department, cardboard 520 flows into next station.

The card pushing mechanism 510 in this embodiment is disposed on the back plate of the card 520, so as to prevent the manual work from affecting subsequent board splitting actions due to the incorrect position of the card 520 when the card 520 is placed. As shown in fig. 12, the push plate structure employs a push-out cylinder 511 as a power unit, and the push plate frame 512 is driven by the push-out cylinder 511 to push the card plate 520 to a fixed position, so that the position where the claws are forked into the card plate 520 each time is fixed.

The discharge level 530 in this embodiment is shown in figure 13 as a stacking position for products to be palletized, with the upstream end thereof abutting the buffer roller. The discharge position 530 is provided with a rotary motor 531 and a rotary bearing 532 for driving the clamping plate 520 on the roller of the discharge position 530 and the product to be palletized to rotate 180 degrees. The rollers of the material placing position 530 are divided into three sections, and three transmission gears are arranged on a front-end driving shaft and used for driving all the rollers to rotate simultaneously; the gap between the rollers can facilitate the next process operation. A baffle 533 and an inductive switch are mounted at the end of the roller to protect and detect the card 520. It should be noted that the product to be palletized in this embodiment may be any product that can be stacked, such as a television, and the like, and this embodiment does not limit this.

and S300, moving the product to be stacked on the material taking position to a preset clamping plate through a stacking mechanism so as to realize stacking work of the stacked product.

Before the product stacking device is controlled, program setting needs to be carried out according to different products, whether the first product on each layer needs to rotate or not, the number of stored products of the parallel mechanism, the position of the pushing mechanism and the staggered arrangement among the layers of stacked products are carried out; setting the number of stacked layers; product size setting (affecting the height between layers).

During specific implementation, at first the cardboard position is artifical to put into the assigned position with a certain amount of cardboard, and cardboard powder mechanism further centers the cardboard, and the action of board-dividing mechanism divides the material with the cardboard, and the material level is put in the inflow. The rotary transition mechanism waits for a product assembly line to flow into a product, and if the product is the first product to be stacked, the first product to be stacked is rotated by 180 degrees through the rotary motion mechanism in the rotary transition mechanism, whether the product is rotated in place is judged through the work of the sensor, and the product flows into the parallel operation mechanism after the product is completed. When treating the pile up neatly product and flowing into the back, first push pedal and second push pedal remove simultaneously, will treat the pile up neatly product and remove the storage position, the migration distance is set for by the procedure, it accomplishes to drive the lead screw by the push pedal motor, remove after the assigned position, initial state is got back to first push pedal, the second push pedal is motionless, when next pile up neatly product of taking flows in parallel machine mechanism, first push pedal and second push pedal move simultaneously once more, the distance that first push pedal and second push pedal removed simultaneously equals approximately the width of product, so circulate, until parallel machine mechanism stores the setting value that product quantity reaches each layer, orderly product flows in and pushes away quick-witted mechanism. When all the products to be stacked completely flow into the parallel mechanism, the inductive switch arranged in the parallel mechanism can detect the products to be stacked, and at the moment, the roller conveying mechanism stops operating. After roller conveying mechanism stopped working, first push pedal removed to the direction of second push pedal, and the second push pedal backward movement makes the product that has flowed into parallel machine mechanism put in order through the thrust of first push pedal to beat the area through beating the tape mechanism and handle the product, in order to avoid the product to scatter. The products which are subjected to belt beating flow into the pushing mechanism through the conveying roller, the photoelectric switch at the rear end of the pushing mechanism is triggered, the conveying roller of the pushing mechanism stops moving, the pushing mechanism pushes the ordered products to be stacked to a proper position according to set parameters, and the products to be stacked are located at a preset material taking position at the moment and wait for the stacking mechanism to take materials. When the stacking mechanism takes materials, a jacking cylinder in the pushing mechanism drives a jacking heavy rod to ascend, so that products to be stacked are separated from a conveying roller of the pushing mechanism, the clamping and holding mechanism descends to a material taking position through the lifting motion mechanism, the left clamping and holding claw and the right clamping and holding claw move oppositely through the action of the clamping and holding motor, and a clamping jaw with a right-angle side with a certain width clamps and holds the products to be stacked to reach an appointed position. Then, move to the position of piling up (the material level of putting of cardboard promptly) through horizontal motion mechanism, then wait that the pile up neatly product with the whole layer and move to the material level top of putting, then go down to appointed height (specifically place on which layer) through elevating movement mechanism, press from both sides this moment and embrace the mechanism and loosen, the product is placed on the cardboard because of gravity reason, as above reciprocating, finally accomplishes the work of piling up of whole board product. After the stacking action is completed, the whole plate product is taken away by the next process, and the equipment is circulated. The whole control process in the embodiment is automatic, manual feeding and conveying processes are not needed, labor cost is saved, and product stacking efficiency is improved

In summary, the invention discloses a product stacking device and a control method thereof, wherein the stacking device comprises: the device comprises a rotary transition mechanism, a parallel mechanism, a pushing mechanism and a stacking mechanism.
