[0040] Refer to Figures 1-6, which is a schematic structural diagram of a stack - type cache replenishment device for this embodiment. Its purpose is to solve the problem of low work efficiency in manual replenishment during the replenishment process at the front stage of the existing transparent paper packaging machine. The specific structure in this embodiment will be elaborated in detail below.

[0041] A stack - type cache replenishment device includes a main frame 1.

[0042] Among them, the main frame 1 includes a conveying area 2 for the conveying line to pass through and a replenishment area connected to it. The conveying area 2 and the replenishment area are parallel in the main frame 1. The conveying area 2 is used for the cigarette packet conveying line to pass through; and the replenishment area includes a lifting area 3 in the middle and buffer areas 4 arranged on both sides of the lifting area 3.

[0043] Two sets of three - section drawers 5 for stacking and placing cigarette packets are slidably arranged in the buffer area 4. The two buffer areas 4 increase the maximum replenishment capacity of the replenishment device through four three - section drawers. The three - section drawers 5 are all independently arranged. When the device is running, the empty three - section drawer 5 can be pulled out, and cigarette packets can be directly palletized into the three - section drawer 5, reducing an operating table and the palletizing process on the operating table. Moreover, at least one or more three - section drawer 5 units in the replenishment device can continuously replenish. The continuous working mode improves the replenishment efficiency and meets the increasing replenishment quantity and the demand for efficient replenishment in the tobacco industry.

[0044] A lifting mechanism 6 for lifting the cigarette packets in the three - section drawer 5 is arranged in the lifting area 3. The lifting mechanism 6 moves up and down to drive the cigarette packets at the bottom of the three - section drawer 5 to rise to the top layer; a transfer mechanism 8 for transferring the cigarette packets in the three - section drawer 5 to the conveying line in the conveying area 2 is arranged at the top of the main frame 1. Thus, the cigarette packets at the top layer of the three - section drawer 5 are transferred to the cigarette packet conveying line in the conveying area 2 through the transfer mechanism 8. Furthermore, the stack - type cache replenishment device replaces the manual replenishment process, uses automated equipment to improve the automation level of the production site, and thus achieves the purpose of improving work efficiency, reducing labor input, and lowering the labor intensity of operators.

[0045] Specifically, two profile vertical beams 41 are arranged in the buffer area 4. The two profile vertical beams 41 divide the buffer area 4 into two buffer sub - areas 42, so that the two buffer areas 4 form four buffer sub - areas 42. Two sets of three - section drawer slide rails 43 are used to arrange the three - section drawers 5 in each buffer sub - area 42, and a drawer guide plate 44 acting on the three - section drawer 5 is arranged on one side of the buffer sub - area 42.

[0046] In this embodiment, within a cache sub-region 42 of the buffer 4, two sets of three-section drawer slides 43 are mounted on a profile on one side of the main body frame 1, and the drawer guide plate 44 is directly mounted on one side of the profile vertical beam 41. In another cache sub-region 42, two sets of three-section drawer slides 43 are mounted on the other side of the profile vertical beam 41, and the drawer guide plate 44 is directly mounted on the profile on the other side of the main body frame 1, so that the two three-section drawers 5 can slide into or out of the two cache sub-regions 42 of the buffer 4 in the same direction.

[0047] Specifically, the three-section drawer 5 includes a vertical back plate 51, with a vertical inner side plate 52 and a vertical outer side plate 53 respectively arranged on both sides of the vertical back plate 51, and a drawer support plate 54 is provided at the bottom of the vertical back plate 51; cigarette packs are stacked on the drawer support plate 54; both ends of the drawer support plate 54 are respectively connected perpendicularly to the vertical inner side plate 52 and the vertical outer side plate 53. A first through groove 55 and a second through groove 56 are respectively formed in the vertical inner side plate 52 and the drawer support plate 54, and the lowest point of the first through groove 55 is lower than the horizontal plane where the drawer support plate 54 is located.

[0048] The three-section drawer slide 43 adopts an existing three-section drawer slide, and its specific model is SEEH15020. Two sets of three-section drawer slides 43 are installed in the cache sub-region 42 and are simultaneously connected to the vertical back plate 51 of the three-section drawer 5. Furthermore, the three-section drawer 5 can be slid into or out of the cache sub-region 42 through the three-section drawer slide 43.

[0049] Specifically, the lifting mechanism 6 includes two sets of lifting components 7 arranged back to back. The lifting component 7 includes a lifting mounting upper plate 71 and a lifting mounting lower plate 72. A profile is provided between the two lifting mounting upper plates 71 or the two lifting mounting lower plates 72 of the two sets of lifting components 7. The two lifting mounting upper plates 71 or the two lifting mounting lower plates 72 are mounted back to back on the profile, so that the two lifting mounting upper plates 71 or the two lifting mounting lower plates 72 are mounted between the two profile vertical beams 41 adjacent to the two buffers 4 through the profile.

[0050] Two first ball screws 74 are respectively installed between the lifting mounting upper plate 71 and the lifting mounting lower plate 72 through a first screw support seat 73. First servo motors 75 are respectively installed on the left and right sides of the lifting mounting upper plate 71, and the output shafts of the first servo motors 75 are connected to the first ball screws 74 through couplings. Among them, the first screw support seat 73 adopts an existing ball screw support seat, and its specific model is BF-12. The first servo motor 75 adopts an existing 400W servo motor with a brake, and its specific model is MS1H4-40B30CB-A334R.

[0051] On the vertical profile beams 41 near the lifting area 3, there are respectively first lifting slide rails 76 that fit with the first ball screw 74; a first lifting slider 77 is slidably arranged on the first lifting slide rail 76; above the first lifting slider 77, it is connected to the first screw nut 79 on the first ball screw 74 through a first lifting nut seat 78; thus, by driving the first ball screw 74 to rotate with the first servo motor 75, the rotation of the first ball screw 74 drives the first screw nut 79 to move up and down on the first ball screw 74, and then the first screw nut 79 drives the first lifting slider 77 to move up and down on the first lifting slide rail 76 through the first lifting nut seat 78.

[0052] Below the first lifting slider 77, there is a support arm 45 extending to the buffer area 4. The support arm 45 passes through a first through slot 55 reserved on the vertical inner side plate 52, and a second through slot 56 for the support arm 45 to pass through is provided on the drawer support plate 54; when the first lifting slider 77 moves up and down on the first lifting slide rail 76, the first lifting slider 77 drives the support arm 45 to displace up and down in the first through slot 55, so that the support arm 45 passes through the second through slot 56 to lift the cigarette packs stacked on the drawer support plate 54, continuously exposing the cigarette packs stacked on the drawer support plate 54 to the highest position of the three - section drawer 5 for the transfer mechanism 8 to adsorb and transfer for supplementary packaging operations.

[0053] Specifically, the transfer mechanism 8 includes transfer components 9 respectively arranged above the two buffer areas 4. The transfer component 9 includes a sliding component 91 installed on the main body frame 1 and an adsorption component 92 installed on the sliding component 91. The adsorption component 92 is used to adsorb the cigarette packs stacked on the top layer of the three - section drawer 5. At the same time, the sliding component 91 drives the adsorption component 92 to displace between the conveying area 2 and the buffer area 4.

[0054] The sliding component 91 includes two profile cross - beams 9101 installed on the main body frame 1 at the top of the buffer area 4, and two adapter plates 9102 installed at both ends above the two profile cross - beams 9101; at the central part of the lower surface of the two adapter plates 9102, a second ball screw 9104 is arranged through a second screw support 9103. The second screw nut 9105 on the second ball screw 9104 is provided with an adsorption mounting plate 9107 through a second screw nut seat 9106; a transfer slide rail 9108 is arranged on the lower surface of the profile cross - beam 9101, and a transfer slider 9109 slidably connected to the transfer slide rail 9108 is arranged on the adsorption mounting plate 9107;

[0055] On the upper surface of one of the adapter plates 9102, there is a second servo motor 9110. The output end of the second servo motor 9110 is provided with a driving wheel 9111, and the end of the second ball screw 9104 is provided with a driven wheel 9112. The driving wheel 9111 is connected to the driven wheel 9112 through a synchronous belt 9113.

[0056] In this embodiment, the driving pulley 9111 at the end of the output shaft of the second servo motor 9110 drives the driven pulley 9112 through the synchronous belt 9113. The driven pulley 9112 drives the second ball screw 9104 to rotate, causing the second ball screw nut 9105 to displace on the second ball screw 9104. Further, the second ball screw nut 9105 drives the adsorption mounting plate 9107 to displace through the second ball screw nut seat 9106. At the same time, a transfer slide rail 9108 is provided on the lower surface of the profile cross beam 9101, and a transfer slide block 9109 slidably connected to the transfer slide rail 9108 is provided on the adsorption mounting plate 9107. The transfer slide rail 9108 and the transfer slide block 9109 are slidably connected to provide sliding guidance for the displacement of the adsorption mounting plate 9107, so that the adsorption mounting plate 9107 displaces between the conveying area 2 and the buffer area 4. Among them, the second screw support seat 9103 adopts an existing ball screw support seat, and its specific model is BF-12. The second servo motor 9110 adopts an existing 400W servo motor, and its specific model is MS1H4-40B30CB-A331R.

[0057] Specifically, the adsorption assembly 92 includes two sets of adsorption sub-assemblies 921 provided on the lower surface of the adsorption mounting plate 9107. The adsorption sub-assembly 921 includes a lifting cylinder 922 mounted on the lower surface of the adsorption mounting plate 9107, and an adsorption cross plate 923 is provided at the end of the output shaft of the lifting cylinder 922. Second lifting slide rails 924 are respectively provided at both ends of the upper surface of the adsorption cross plate 923, and second lifting slide blocks 926 are provided on the lower surface of the adsorption mounting plate 9107 through a slide block mounting plate 925. The second lifting slide rails 924 are slidably connected to the second lifting slide blocks 926, and a plurality of vacuum suction cups 928 are evenly provided on the lower surface of the adsorption cross plate 923 through a suction cup mounting plate 927.

[0058] In this embodiment, the distance between the two sets of adsorption sub-assemblies 921 is the same as the distance between the two sets of three-section drawers 5 in the buffer area 4, so that the two sets of three-section drawers 5 stacked on the top layer of cigarette packs are adsorbed by the two sets of adsorption sub-assemblies 921 respectively.

[0059] When adsorption is required, under the sliding guidance of the second lifting slide rail 924 and the second lifting slider 926, the output end of the lifting cylinder 922 drives the adsorption cross plate 923 to move up and down, so that the adsorption cross plate 923 approaches or moves away from the cigarette packs stacked on the top layer of the three-section drawer 5. When approaching, the vacuum suction cups 928 installed on the lower surface of the adsorption cross plate 923 adsorb the cigarette packs. After the adsorption is completed, it moves away from the three-section drawer 5. Then, the sliding assembly 91 drives the vacuum suction cups 928 to transfer from the conveying area 2 to the buffer area 4, and releases the adsorbed cigarette packs on the conveyor line. Among them, the lifting cylinder 922 uses an existing stainless steel mini cylinder, and its specific model is MFC32C×50SCA. The vacuum suction cup 928 uses an existing vacuum suction cup, and its specific model is SFA35S.
