After the control mechanism determines that there is a vacant position for dismantling the pallet on the first double-chain roller machine through the second photoelectric switch, the control mechanism controls the loading roller machine to start and transport the bottom pallet of the wooden box to the top of the first double-chain roller machine at the dismantling mechanism; The control mechanism determines that there is a wooden box bottom support at the dismantling position through the second photoelectric switch, detects the grabbing and judgment of the wooden box bottom support on the second layer below through the third photoelectric switch, and positions the wooden box bottom support stack through the first lifting and stopping mechanism and the second lifting and stopping mechanism; The control mechanism determines that there is a vacancy through the photoelectric switch of the buffer position of the second double-chain roller machine. After the claws of the disassembling mechanism grab and lift the wooden box bottom trays of the second layer and above, the control system controls the first double-chain roller machine to move and transfer a wooden box bottom tray of the lowest layer to the second double-chain roller machine.

The first lifting support frame 77 is arranged above the second base frame 88. A pair of third pulleys 91 are arranged on both sides of the first lifting support frame 77 corresponding to the second slide rail groove 81 on the second base frame 88. The third pulleys 91 are slidably connected with the second slide rail groove 81. The upper end surfaces of the first lifting support frame 77 parallel to the production line are fixedly installed with mounting plates 76, and a plurality of fourth rollers 75 are rotatably installed between the pair of mounting plates 76. The first positioning seat 80 is fixedly installed on the first lifting support frame 77 at the position corresponding to the fourth pulley 82, and the first in-position detection plate 92 is arranged at the position corresponding to the first fixed plate 86 on the first lifting support frame 77 and the second base frame 88.

When the first lifting support frame 77 on the transfer position 1 drops to the lowest point, the wooden box bottom support above the fourth roller 75 and the auxiliary roller 90 falls on the conveyor chain on the first double-row chain machine support frame crossbeam 73, and the first double-row chain machine drive motor 70 drives the conveyor chain to rotate, moving the wooden box bottom support from the transfer position 1 to the packing position.

[0028] The material platform 13 is located outside the packing position of the first double-row chain machine. Materials such as circuit breakers, cartons and iron frames are placed in order on the material platform 13. The power-assisted mechanical arm 14 is located on one side of the packing position, and the worker is located on the other side of the packing position. The worker uses the power-assisted mechanical arm 14 to place the materials on the wooden box bottom support and fix the materials. The wooden box bottom support after the material packing is sent back to the transfer position 1 through the first double-row chain machine, and the first lifting support frame 77 rises to a level higher than the first double-row chain machine support frame beam 73 and is flush with the third double-chain roller machine 6, so that the wooden box bottom support loaded with materials is transported from the first lifting transfer machine 72 to the third double-chain roller machine 6, and then enters the next process for sealing through the third double-chain roller machine 6.

[0029] The third double-chain roller machine 6 has the same structure as the second double-chain roller machine 4. The third double-chain roller machine 6 has two buffering positions. The third double-chain roller machine 6 is located between the first lifting and transferring machine 72 and the second lifting and transferring machine 94 of the box sealing mechanism 7. The fifth roller is driven by the fifth roller driving motor to realize the conveyance of the wooden box bottom support after boxing. The eighth photoelectric switch and the ninth photoelectric switch are respectively arranged at both ends of each buffering position of the third double-chain roller machine 6. The fifth lifting and stopping mechanism and the sixth lifting and stopping mechanism are respectively arranged at the rear end of each buffering position. The fifth lifting and stopping mechanism and the sixth lifting and stopping mechanism have the same structure as the first lifting and stopping mechanism 32.

[0030] like Figure 12-14As shown, the sealing mechanism 7 includes a second jacking and transferring machine 94 and a second double-row chain machine 95. The second double-row chain machine 95 is divided into a transfer position 2, a driving position and a sealing position in the length direction. The driving position and the sealing position at the outer end extend outward for a section relative to the production line. The second jacking and transferring machine 94 is installed in the frame of the second double-row chain machine support frame at the transfer position 2 at the inner end. The second jacking and transferring machine 94 is connected to the third double-chain roller machine 6 and the unloading roller machine 8. When the second jacking and transferring machine 94 is jacked to the highest point, it is flush with the third double-chain roller machine 6 and the unloading roller machine 8. The second jacking and transferring machine 94 has the same structure as the first jacking and transferring machine 72. The second jacking and transferring machine 94 is provided with a sixth roller drive motor, a third in-place detection plate, a sixth proximity switch and a seventh proximity switch. The sixth proximity switch is located above the seventh proximity switch. The sixth proximity switch and the seventh proximity switch cooperate with the third in-place detection plate to detect whether the wooden box bottom support has reached the transfer position 2.

[0031] The second double-row chain machine 95 has a similar structure to the first double-row chain machine, including a second double-row chain machine support frame and a second double-row chain machine drive motor. The height of the second double-row chain machine support frame is lower than the height of the third double-chain roller machine 6, and higher than the lowest height of the second lifting transfer machine 94 after it is lowered. The second double-row chain machine support frame is a rectangular frame structure welded by square steel and angle steel, and a transfer position 2, a driving position and a box sealing position are formed in the frame; the transfer position 2 and the box sealing position are respectively located at the two ends of the length direction of the frame structure, and the driving position is located between the transfer position 2 and the box sealing position. The transfer position 2 has the same structure as the transfer position 1 in the packing mechanism 5, and will not be repeated; wherein, a third positioning stop bar 97 is fixedly installed on the upper side of the transfer position 2 away from the box sealing position, and a tenth photoelectric switch 100 is fixedly installed just above the inner end of the crossbeam in the length direction of the second double-row chain machine support frame and at the lower end of the third positioning stop bar 97. The tenth photoelectric switch 100 is used to detect whether the wooden box bottom bracket has reached the transfer position 2. The fourth baffle 98 is respectively arranged on the outer side of the cross beam of the second double-row chain machine support frame at the sealing position and the driving position, and the fifth baffle 99 is installed above the outer end of the second double-row chain machine support frame in the width direction between a pair of fourth baffles 98. The direction of the fifth baffle 99 is perpendicular to the fourth baffle 98. The end of at least one side of the fourth baffle 98 away from the transfer position 2 is provided with a second in-place detection hole. The outer side of the second in-place detection hole is matched with an eleventh photoelectric switch 101. The eleventh photoelectric switch 101 is used to detect whether the wooden box bottom bracket has reached the sealing position. The driving position is used to install the second double-row chain machine drive motor and realize the drive of the second double-row chain machine 95. Since the wooden box bottom bracket does not need to stay at the driving position after boxing, the driving position does not need to be provided with a supporting roller; the sealing position is provided with a jacking rotating platform 96, which is used to rotate the wooden box bottom bracket and other components during the sealing process.

[0032] The jacking and rotating platform 96 consists of two parts: a jacking mechanism and a rotating mechanism. The jacking mechanism is similar in structure to the first jacking and transferring machine 72, and the lifting and lowering of the second lifting support frame 110 is achieved through the eccentric principle. The jacking mechanism includes the second lifting support frame 110 and the third base frame 113. The second lifting support frame 110 is provided with a fifth proximity switch 111. The third base frame 113 has the same structure as the second base frame 88, which will not be repeated here. A second lifting motor 114 is installed in the middle of the third base frame 113, and the eccentric block is driven to rotate by the second lifting motor 114. Vertical third slide rail grooves 115 are arranged near the four corners of the third base frame 113. A second vertical fixed plate 116 is arranged between a pair of third slide rail grooves 115 at one end of the third base frame 113 near the driving position. The third slide rail groove 115 and the second fixed plate 116 cooperate with the pulley on the second lifting support frame 110. A second vertical hollow structure is arranged in the middle of the second fixed plate 116. A fourth proximity switch 117 and a third proximity switch 118 are fixedly arranged in the second hollow structure in upper and lower distributions; the fourth proximity switch 117 and the third proximity switch 118 cooperate with the second in-position detection plate arranged on the second lifting support frame 110 to detect whether the second lifting support frame 110 is lifted and put in place.

[0033] The rotating mechanism is located above the jacking mechanism, and includes a hollow rotating platform 109 and a rotating plate 107. The hollow rotating platform 109 is fixedly arranged at the center above the second lifting support frame 110. The hollow rotating platform 109 is a prior art and will not be described in detail; a rotating plate 107 is arranged on the hollow rotating platform 109. The rotating plate 107 is fixedly arranged above the hollow rotating platform 109, and a second groove 108 is arranged at the center of the upper end surface of the rotating plate 107. The second groove 108 is parallel to the middle supporting leg of the wooden box bottom support, and a clamping mechanism is arranged in the second groove 108; a positioning protrusion 112 is arranged on the lower end surface of the rotating plate 107. The clamping mechanism includes a clamping plate 104, a support guide rod 103, a guide rod mounting seat 102, a cylinder 106 and a support pad 105, which realizes the clamping of the middle supporting leg of the wooden box bottom support, and prevents the wooden box bottom support from deviating when the rotating platform rotates and affecting the sealing work. The clamping plates 104 include two, which are symmetrically and parallelly arranged in the second groove 108. The clamping plates 104 are parallel to the middle supporting legs of the wooden box bottom support. The upper end height of the clamping plates 104 is higher than the rotating plate 107 and lower than the highest height of the middle supporting legs of the wooden box bottom support, so as to clamp the middle supporting legs of the wooden box bottom support; a supporting pad 105 is arranged between the two clamping plates 104, and two pairs of guide rod mounting seats 102 and three cylinders 106 are respectively arranged in the second grooves 108 on the outer sides of the two clamping plates 104. After the two support guide rods 103 pass through the two clamping plates 104, the two ends of the support guide rods 103 are fixedly installed in the two opposite guide rod mounting seats 102, and the support guide rods 103 are slidably connected to the clamping plates 104. The cylinder 106 is arranged on the outside of the two clamping plates 104. A cylinder 106 is arranged in the center of the outside of the clamping plate 104 on the inner side of the sealing position close to the driving position. At least two cylinders 106 are arranged on the other clamping plate 104 located outside the sealing position. The outer end of the piston rod of the cylinder 106 is fixedly connected to the clamping plate 104. During operation, the two cylinders 106 on the outer side of the sealing position move into place first, and then the cylinder 106 on the inner side of the sealing position moves. After the eleventh photoelectric switch 101 senses that the wooden box bottom support has arrived at the sealing position, the control mechanism stops the second double-row chain machine 95, and the wooden box bottom support may be offset to the outside of the sealing position. The clamping plate 104 outside the sealing position is pushed by two cylinders 106 to push the wooden box bottom support to the specified position, and a cylinder 106 on the other side is actuated to enable the clamping plate 104 to clamp the wooden box bottom support; when the cylinder 106 pushes the clamping plate 104, the support guide rod 103 guides the clamping plate 104 to ensure that the wooden box bottom support is not offset; when the rotating plate 107 rotates after clamping, the support guide rod 103 can increase the supporting force of the clamping plate 104 to prevent offset from affecting the sealing quality.A support pad 105 is provided between the two clamping plates 104 and at the center of the rotating plate 107. The support pad 105 is arranged parallel to the clamping plates 104. The length of the support pad 105 is less than the spacing between the two support guide rods 103. The width of the support pad 105 is less than the width of the support legs of the wooden box bottom support. The height of the support pad 105 is flush with the upper end surface of the rotating plate 107, and together with the upper end surface of the rotating plate 107, the support of the wooden box bottom support is realized. Four positioning protrusions 112 are arranged at 90° intervals along the circumference of the lower end surface of the rotating plate 107. The positioning protrusions 112 cooperate with the fifth proximity switch 111 arranged on the second lifting support frame 110; each triggering of the fifth proximity switch 111 represents that the rotating plate 107 rotates 90 degrees.

The box side panel or the box top panel is grabbed by the loading claw of the box board loading robot 11 and the box side panel or the box top panel is placed in the set position.

[0035] The stapling and sealing robot 9 is a prior art and is located on one side of the sealing position of the second double-row chain machine 95. When the wooden box board loading robot 11 places the wooden box side panels or the wooden box top cover panels in the set position, the stapling and sealing robot 9 performs stapling and sealing according to the settings.

[0036] The automated production line also includes a control mechanism: 1. The control mechanism adopts PLC logic control; 2. The control mechanism sends signals to the pallet dismantling servo motor, drive motor, stapling and sealing robot 9 and wooden box board loading robot 11 of each mechanism through PROFINET communication; 3.

Embodiment 2

[0037] A control method for a material packing and sealing automated production line provided in embodiment 1 includes the following steps: S1: First, the stacked wooden box bottom pallet 16 is placed on the loading roller machine 2 at the loading port by the AGV forklift 1. The first photoelectric switch 19 on one side of the loading roller machine 2 recognizes that there is material and transmits the material signal to the control mechanism. The control mechanism determines whether there is an empty space on the first double-chain roller machine 15 through the second photoelectric switch 31; Yes: start the first roller drive motor 24 of the feeding roller machine 2 and the second roller drive motor 51 of the first double-chain roller machine 15 to transport the wooden box bottom support stack 16 to the depalletizing mechanism 3, and execute step S2; No: wait for the second photoelectric switch 31 to send a signal indicating that the first double-chain roller machine 15 has a vacancy.

[0038] S2: The wooden box bottom stack 16 is transported to the depalletizing position on the first double-chain roller machine 15. At this time, the control mechanism controls the second lifting and stopping mechanism 29 to rise to prevent the wooden box bottom stack 16 from being transmitted to the next process, so that the wooden box bottom stack 16 remains in the depalletizing position; at this time, the two second photoelectric switches 31 at both ends of the front side of the first double-chain roller machine 15 detect the presence of material, and the control mechanism receives the material presence signal and controls the second roller drive motor 51 and the first roller drive motor 24 to stop running, and at the same time controls the first lifting and stopping mechanism 32 to rise, and then executes S3-1.

[0039] S3-1: The control mechanism receives a signal indicating that there is material at the dismantling position, the initial position of a pair of hand grippers 34 is the highest point and the initial state is open, the control mechanism controls the dismantling servo motor in the dismantling servo motor box 36 to start and run to the first set position, so that the hand grippers 34 are placed at the supporting legs of the second layer of wooden box bottom supports below, and the control mechanism determines whether there is a wooden box bottom support at the second layer of the bottom of the wooden box bottom support stack 16 through the third photoelectric switch 33; Yes: the control mechanism controls the hydraulic cylinder 44 to move the grippers 34 at both ends to retract and tighten, and places the support plate 42 of the grippers 34 in the gap between the support legs of the second layer of wooden box bottom support at the bottom. After the hydraulic cylinder 44 is completely retracted, the control mechanism receives the grabbing position signal to control the disassembly servo motor to operate and operate to the second set position (the height of the grippers 34 at the second set position is higher than the height of the grippers 34 at the first set position), so that the grippers 34 lift the second layer and above wooden box bottom supports to a certain height (the lifting height is set by the program and does not affect the backward transmission of the wooden box bottom supports at the bottom of the first layer), and then execute step S4; No: the control mechanism controls the dismantling servo motor to drive the claw 34 back to the initial position (i.e. the highest point, which does not hinder the feeding port from conveying the wooden box bottom support stack 16 to the dismantling mechanism 3), and at the same time makes the first lifting and stopping mechanism 32 descend to the origin, and then executes step S4.

[0040] S3-2: When the control mechanism detects that there is no trigger signal from the second photoelectric switch 31 and the third photoelectric switch 33, the control mechanism first determines the position of the gripper 34; when the gripper 34 is at the second set position, the control mechanism controls the tray dismantling servo motor to run to the third set position (the height of the gripper 34 at the third set position is lower than the height of the gripper 34 at the first set position), so that the bottom support of the second layer of wooden boxes lifted by the gripper 34 is placed on the second double-chain roller machine 4. After reaching the third set position of the tray dismantling servo motor, the control mechanism controls the piston rod of the hydraulic cylinder 44 to extend. At this time, both the second photoelectric switches 31 are triggered to sense, and the control mechanism detects that there is a material signal at the tray dismantling position, and then executes S3-1.

At this time, the third lifting and stopping mechanism 56 is in a raised state (origin) to stop the wooden box bottom support at the second cache position of the second double-chain roller machine 4. At the same time, the fourth photoelectric switches 53 at both ends of the second cache position of the second double-chain roller machine 4 are triggered to detect the material signal. The control mechanism receives the material signal and controls the second roller drive motor 51 and the third roller drive motor 55 to stop, and the second lifting and stopping mechanism 29 starts to rise to the highest point (i.e., the origin), and then executes S3-2.
