Description

TECHNICAL FIELD

[0001] The present application belongs to the packaging machinery, and particularly relates to a side-pushing type packaging box packing machine. BACKGROUND

[0002] The packing machine is used for arranging multiple packaging boxes and packaging boxes, packing the packaging boxes into the packaging box unfolded through an opening device, and completing the function of outputting the packaging box after sealing. The existing packing equipment is used for placing the unfolded packaging box with the opening facing upward and downward, arranging the material packaging box through an arrangement mechanism to form a layer of packaging box rectangular matrix, moving and putting the layer of packaging box matrix into the packaging box through a box suction mechanism, returning the box suction mechanism to the initial position, waiting for the next layer of packaging box matrix to be formed, and repeating the suction and putting actions until the packaging box is filled with the required number of layers of packaging box matrix, and then the subsequent sealing and outputting are performed through a sealing mechanism.

[0003] The packing machine has the following problems:

[0004] 1. The arrangement mechanism is provided with a blocking rail at the end of a conveying belt, and after a certain number of packaging boxes are stored, the driving device is used to push the packaging boxes horizontally away from the storage platform, the driving device returns, and the above actions are repeated until a layer of packaging box matrix with the required number of packaging boxes is stored, and then the packaging box matrix is carried into the packaging box by the box suction mechanism, and the box suction mechanism repeatedly carries the next layer. The arrangement mechanism uses horizontal pushing storage, and the box suction mechanism repeatedly carries and sucks the packaging box for storage, so that the overall carrying path is long, the packing speed is affected, and the packing efficiency is low.

[0005] 2. The opening device includes a translation mechanism, a vacuum suction cup arranged on the translation mechanism, and a blocking device arranged on the packaging box running path. When the opening device is in action, the packaging box is taken out by moving and sucking the plane A of the four surfaces of the packaging box through the vacuum suction cup, the adjacent plane B beside the plane A is limited by the blocking device, the plane B is folded along the preset crease, the plane A is unfolded perpendicularly, and the packaging box is unfolded.

[0006] The opening device can accurately open the packaging box with a rectangular box shape, but for a square packaging box with equal length and width, two groups of adjacent planes are easily formed in the form of L type when the packaging box is unfolded, so that the packaging box cannot be unfolded, and the production rhythm is affected.

[0007] 3. The packaging box buffer warehouse stroke is designed to form an angle with the ground, and the packaging box is lowered by relying on its own gravity and counterweight, so that the packaging box is automatically replenished. Meanwhile, a circular blocking block is arranged at the outlet position of the warehouse to prevent the packaging box from falling.

[0008] Because the bottom surface of the existing corrugated paper packaging box in contact with the warehouse is rough and cannot be controlled, the packaging box relies on its own gravity and counterweight to descend, and the packaging box may be stuck; meanwhile, the packaging box may be deformed or damaged before use due to the blocking of the blocking block during the taking process, thereby affecting the qualified rate.

[0117] During operation, the servo motor 5 of the lifting mechanism and the servo motor 50 of the translation reciprocating mechanism 37 are controlled by the controller 183 to work.

[0118] 1. A group of packaging boxes conveyed by the conveying device is received by the limiting support plates 24 symmetrically arranged on the fixed clamp group 3 and the movable clamp group 8 until the packaging boxes reach the trigger arm 16 and push the trigger arm 16 to flip and trigger the corresponding proximity switch 18.

[0119] 2. The proximity switch 18 sends a signal to the controller 183 of the packing machine, the servo motor 5 of the lifting mechanism is started by the controller, the synchronous belt mechanism is driven to work, and the support plate 15 is driven to move upwards, so that the group of packaging boxes between the two limiting support plates 24 is pushed upwards, when the packaging boxes move upwards to the swinging support bar 30, the swinging support bar 30 is pressed to swing outward and retract, when the packaging boxes move upwards to exceed the swinging support bar 30, the swinging support bar 30 is reset under the action of the compression spring and supports the group of packaging boxes pushed up;

[0120] 3. The servo motor 5 drives the synchronous belt mechanism to work in reverse, and drives the support plate 15 to move downwards and reset, the above-mentioned operation is repeated until the stacked groups of packaging boxes reach the required number of layers and are clamped on the swinging support bar 30; the servo motor 5 of the lifting mechanism drives the synchronous belt mechanism to work, and drives the support plate 15 to move upwards, so that the stacked groups of packaging boxes are pushed to the height of the storage platform;

[0121] 4, start the servo motor 50 of the translation reciprocating mechanism 37, drive the synchronous belt mechanism to operate, and drive the push hand 35 at the lower end of the cantilever frame 36 to push the stacked multiple groups of packaging boxes into the storage platform; when the packaging boxes enter the storage platform, the servo motor 5 of the lifting mechanism is started to drive the synchronous belt mechanism to operate in reverse, and drive the supporting plate 15 to descend and reset, so that the next group of packaging boxes conveyed by the conveying device can be continuously received;

[0122] 5, when the push hand 35 pushes the stacked multiple groups of packaging boxes to the position, the cylinder is controlled to retract and drive the gear 49 to ascend, the gear 49 rotates under the limiting action of the fixed rack 58 while ascending, thereby driving the movable rack 44, the cantilever frame 36 and the push hand 35 to move upwards, after moving upwards, the servo motor 50 is controlled to reverse, the push hand 35 is driven to move reversely by the synchronous belt mechanism, and when moving to the rear stop point, the cylinder is controlled to extend, so that the push hand 35 can return to the initial position and prepare for the next pushing;

[0123] 6, since the running track of the push hand 35 is a rectangle, the push hand 35 will not affect the upward pushing of the lifting mechanism when resetting, so that the box pushing and box lifting actions can be performed simultaneously; finally, the packaging boxes can complete the final stacking type before boxing on the storage platform, so that the stacked multiple groups of packaging boxes can be pushed into the packaging box at one time by the box pushing mechanism 182.

[0124] As shown in Figures 15-21 , the box pushing mechanism 182 includes a pushing bracket 34 arranged in the rack 185, the pushing bracket 34 is a rectangular frame and is connected with the supporting plate frame 1 through connecting plates and bolts, a translation reciprocating mechanism 37 driven by a servo motor 50 is installed on the pushing bracket 34, for driving the push hand 35 to move translationally and reciprocally to realize box pushing; an elevating mechanism 38 is connected to the translation reciprocating mechanism 37, the lower end of the elevating mechanism 38 is connected with the push hand 35, for driving the push hand 35 to move up and down reciprocally.

[0128] During operation, the servo motor 17 is started by the controller, and the lifting mechanism 5 is moved horizontally by the synchronous belt mechanism 8, which in turn moves the pusher 2 horizontally, automatically pushing a set of packaging boxes sorted by the sorting mechanism into the front storage platform or packaging box.

[0129] After the pusher 2 moves forward to its position, the controller starts the power source 47, i.e., the cylinder retracts, which drives the gear 16 to move upward. While moving upward, the gear 16 rotates under the limiting action of the fixed rack 25, thereby driving the cantilever 3 and the pusher 2 to move upward through the movable rack 11. After moving upward, the servo motor 17 is started to reverse, and the pusher 2 is driven to move in the opposite direction through the synchronous belt mechanism 8. When it moves to the rear stop point, the control cylinder extends, which can drive the pusher 2 back to the initial position.

[0170] When working, the sealing mechanism has the following steps:

[0171] 1. The packaging box is sent into the space between the front ends of the two sets of upper synchronous belt assemblies 125 and lower synchronous belt assemblies 124 through the synchronous belt mechanism 101 of the opening mechanism. The tongue cylinders 177 are controlled to extend by the controller, so as to drive the tongue plates 178 to turn inward and support the long tongues on the upper and lower sides of the two ends of the packaging box. Then, the packaging box is pushed into the packaging box through the box pushing mechanism 182 arranged on one side of the sealing device.

[0172] 2. After the packaging box is pushed into the packaging box by the box-pushing mechanism of the carton packer, the front folding tongue cylinder 166 is started to retract by the controller. The crank 170 and the connecting block 168 drive the two swing rods 169 to swing inward at the same time. When swinging, under the action of the connecting block 168, the folding tongue plate rotates inward while following the swing rods 169, thereby folding off the short tongue on one side of the packaging box.

[0173] 3. The control system of the packing machine simultaneously starts the rear flap cylinders 164 of the two rear flap mechanisms 126, which drive the sealing plate to slide forward at the same time, thereby simultaneously folding off the other side of the short flap at both ends of the packaging box and pressing down the previously folded side of the short flap.

[0174] 4. Control the servo motor 145 to start, drive the drive shaft 142 to rotate, and drive the drive shaft 130 to rotate through the bevel gear pair 144 and the intermediate shaft 149, thereby driving the two sets of upper synchronous belt assemblies 125 and lower synchronous belt assemblies 124 to operate simultaneously. The packaging box is conveyed from front to back through the limit block 162; at the same time, control the rear flap cylinder 164 to reset, drive the sealing plate to follow the packaging box and keep pressing the short flaps on both sides of the packaging box.

[0175] 5. When the packaging box is conveyed to the symmetrical sealing tongue mechanism 131, the sealing tongue cylinder 156 is started, which drives the tongue pressing plate 154 to flip inward, folding down the long tongues on the upper and lower sides of the packaging box at the same time, and pressing down the short tongues on both sides.

[0176] 6. The packaging box continues to be conveyed backward. When it travels between the two sealing cores 132, the long tongues on both sides of the packaging box are sealed by the tape of the sealing core 132 and then the tape is cut. With the operation of the upper and lower synchronous belt assemblies, the sealed packaging box is output.

[0177] The overall working process of the side-push type packaging box packing machine is as follows:

[0178] 1. The material packaging boxes are queued and enter the sorting mechanism 186 through the conveyor belt mechanism 180. The sorting mechanism receives the material packaging boxes through two limiting trays 24, which limit the bottom and two sides of the material packaging boxes. The material packaging boxes are queued and move forward along the limiting trays 24 until they contact the front baffle 6, triggering the proximity switch 18 and sending a signal to the controller 183.

[0179] 2. The controller 183 controls the servo motor 5 to start, and drives the pallet 15 to push a set of material packaging boxes between the two limit pallets 24 upward through the synchronous belt mechanism 4. When the material packaging box moves upward, it knocks open the two swing bars 30 and causes the swing bars 30 to flip outward until the material packaging box is no longer in contact with them. The swing bars 30 are pushed back to their original position by the pressure spring 29. The servo motor 5 drives the pallet 15 to fall back to its original position, and the bottom of the material packaging box falls onto the swing bars 30 to complete one storage cycle.

[0180] 3. The pallet 15 returns to its initial position, waiting for the next set of packaging boxes to reach the front baffle 6. Then, the servo motor 5 repeats the pushing and lowering action, causing the next set of packaging boxes to stack with the first set and fall onto the swing support 30. This process is repeated until the packaging boxes are stacked into a square array. Once the required number of layers is reached, the pallet 15, driven by the servo motor 5, continues to push until the bottom of this square array of packaging boxes is level with the storage platform 19. The box pushing mechanism 182 pushes this square array of packaging boxes away from the pallet 15 and into the storage platform 19 for storage. The pallet 15 returns to its starting position, ready for the next push. This process is repeated until the storage platform 19 can hold multiple square arrays of packaging boxes, forming the final stack before packing.

[0181] After each push of the box by the pushing mechanism 182, the power source 47 activates, pulling the gear 49 upward and rotating it simultaneously. The movable rack 44 and the cantilever 36 follow suit, moving the pusher 35 away from the material packaging box. After the pusher 35 rises to a certain height, avoiding the height of the subsequent material packaging boxes to be packed, the servo motor 50 activates, driving the pusher 35 back to the starting position. The lifting mechanism 38 moves past the width of the material packaging box and then descends to the starting position of the pushing mechanism, ready for the next push.

[0182] 5. At the same time, after the packaging boxes are loaded into the carton buffer material warehouse 179, the moving V-shaped baffle 98 sticks to the packaging box, and the drive cylinder 81 drives the one-way bearing 83 to move, which drives the chain conveyor assembly 73 to move step by step, pushing the carton forward to replenish the material. The L-shaped hook 87 located at the outlet of the carton buffer material warehouse is driven by the control cylinder 85 to open and close the box as required, and provides it to the box opening mechanism 181 for grabbing.

[0183] 6. Control the second power source 118 in the box opening mechanism 5 to drive the first suction cup bracket 102 to rotate counterclockwise, and at the same time drive the first base plate 113 to rotate from horizontal to vertical, so that the first suction cup 112 picks up the A side of the packaging box in the carton buffer material library; drive the synchronous belt mechanism 101 to operate through the servo motor 117, and use the first suction cup 112 to take the packaging box away from the carton buffer material library.

[0184] 7. Control the first power source 119 in the box opening mechanism 5 to drive the second suction cup 110 to move upward along the arc and stick to the B side of the packaging box to fix it. Then the second power source 118 rotates forward and drives the first suction cup 112 to stick to the A side of the packaging box from vertical to horizontal through the first suction cup bracket 102, completing the box opening action. The servo motor 117 drives the synchronous belt mechanism 101 to operate, and transfers the opened packaging box between the upper and lower synchronous belt components of the sealing mechanism to prepare to receive the material packaging box and send a signal to the controller.

[0185] 8、Push box mechanism 182 to push the material package box into the packaging box, when the push instruction is received, servo motor 50 rotates through synchronous belt mechanism 41 to drive lifting mechanism 38 to translate, thereby driving push hand 35 to push the stacked material package box into the packaging box;

[0186] After the material package box is pushed into the packaging box, start the front tongue cylinder 166 of the two front tongue mechanisms 139, and simultaneously fold down the short tongues on one side of both ends of the packaging box; start the rear tongue cylinder 164 of the two rear tongue mechanisms 126, and simultaneously fold down the short tongues on the other side of both ends of the packaging box through the sealing tongue plate 165; then control the supporting tongue cylinder 177 to retract, drive the supporting tongue plate 178 to evert, and release the long tongues on the upper and lower sides of both ends of the packaging box;

[0187] Then control the servo motor 145 to start, drive the upper and lower synchronous belt assemblies to operate simultaneously through the drive shaft 142, and drive the packaging box after loading to translate; when the packaging box moves close to the sealing tongue mechanism 131, the sealing tongue cylinder 156 starts to extend, pushes the sealing tongue plate 154 and the sealing tongue rod 174 to turn inward, and simultaneously folds down the long tongues on the upper and lower sides of both ends of the packaging box. When the packaging box advances to the sealing box core 132, the adhesive tape of the sealing glue core pastes the long tongues of the packaging box, and the output sealing box is completed.
