[0045] Refer to Figures 1 to 2 , the whole production line for counting and packaging of the present invention includes a bottle arranging machine 2, a desiccant machine 3, a counting machine 4, a capping machine 5, and a labeling machine 6 connected in sequence through a conveyor line 1. An automatic feeding device 7 is arranged beside the bottle arranging machine 2, a hoist 8 is arranged beside the capping machine 5, a counter - punching platform 9 is arranged between the counting machine 4 and the capping machine 5, a three - dimensional buffer device 10 is arranged between the capping machine 5 and the labeling machine 6, label feeding devices 11 are respectively arranged on both sides of the labeling machine 6, and two bottle - winding belt devices 12 are arranged on the labeling machine 6. The counter - punching platform 9 and the three - dimensional buffer device 10 are used to buffer the packaging bottles on the conveyor line 1 or release the cached packaging bottles onto the conveyor line 1. The label feeding device 11 operates in a non - stop label - changing mode and is used to convey the label paper to the bottle - winding belt device 12.

[0046] The bottle arranging machine 2, the desiccant machine 3, the capping machine 5, and the hoist 8 are prior arts. The technical applications and usage instructions of the bottle arranging machine 2, the desiccant machine 3, the capping machine 5, the hoist 8, and the counter - punching platform 9 are very mature and perfect, and their related structures will not be elaborated herein.

[0047] During operation, the packaging bottles are conveyed to the bottle arranging machine 2 through the automatic feeding device 7. The bottle arranging machine 2 arranges the disordered packaging bottles into an orderly state and conveys the orderly - arranged packaging bottles to the desiccant machine 3 through the conveyor line 1. The desiccant machine 3 stuffs the desiccant into the packaging bottles, and then the conveyor line 1 continues to convey the packaging bottles forward. When the packaging bottles are conveyed to the counting machine 4, the counting machine 4 fills the materials into the packaging bottles. After filling, the conveyor line 1 continues to convey the packaging bottles forward. When the packaging bottles pass through the counter - punching platform 9, the packaging bottles can be buffered on the counter - punching platform 9 and then continue to be conveyed forward by the conveyor line 1 to the capping machine 5. The capping machine 5 hangs the bottle cap on the mouth of the packaging bottle and completes the capping and sealing. After the packaging bottle is sealed, the conveyor line 1 continues to convey the sealed packaging bottle forward and conveys the sealed packaging bottle to the labeling machine 6 for labeling. When labeling the packaging bottle, through the mutual cooperation of the label feeding device 11, the labeling machine 6, and the bottle - winding belt device 12, the label is pasted on the packaging bottle. When the equipment in the whole production line breaks down and stops, through the three - dimensional buffer device 10 for buffering or releasing the packaging bottles, the mutual influence between the equipment in the whole production line can be reduced, the utilization efficiency of the equipment in the whole production line can be improved, and the productivity can be increased.

[0048] Refer to Figures 3 to 5, The labeling machine 6 includes a frame 13, on which a main star wheel 14, a bottle inlet star wheel 15, and a bottle outlet star wheel 16 are arranged.

An outlet guardrail 24 is circumferentially arranged around the bottle outlet star wheel 16. An outlet channel 25 is formed between the edge of the bottle outlet star wheel 16 and the outlet guardrail 24.

[0049] When the packaging bottle is conveyed by the conveyor line 1 to the inlet screw 17, the inlet servo motor 18 drives the inlet screw 17 to rotate. Under the action of the inlet screw 17, the packaging bottle is conveyed to the bottle inlet star wheel 15. Under the action of the bottle inlet star wheel 15, the packaging bottle enters the main star wheel 14 along the inlet channel 23, and is limited by the positioning mold 19. Under the action of the main star wheel 14, the packaging bottle moves along the labeling channel 21. When the packaging bottle passes through the two bottle winding belt devices 12 in sequence, the two bottle winding belt devices 12 label the packaging bottle in sequence. After labeling is completed, the packaging bottle continues to move and is conveyed to the bottle outlet star wheel 16. Under the action of the bottle outlet star wheel 16, it enters the conveyor line 1 along the outlet channel 25.

[0050] The positioning mold 19 includes two positioning plates 26 and two rollers 27. The two positioning plates 26 are arranged in parallel up and down, and the inner sides of the positioning plates 26 are fixedly connected to the edge of the main star wheel 14.

The two rollers 27 are arranged in parallel left and right, and each roller 27 is detachably inserted between the two positioning plates 26.

[0051] The connecting shafts at both ends of each roller 27 are telescopic through springs. By means of the springs, the connecting shafts are telescopic so that the connecting shafts are stuck in the connecting holes on the positioning plates 26.

[0052] When limiting the packaging bottle, the outer wall of the packaging bottle is in contact with the two rollers 27, and the curvature of the positioning portion 28 is adapted to the outer wall of the packaging bottle. When switching the bottle type of the packaging bottle, the roller 27 is replaced in a plug-and-play manner, so as to quickly replace the roller 27 without replacing the entire main star wheel 14, which is convenient for replacement and improves work efficiency.

[0057] During operation, the horizontal servo motor 36 drives the horizontal lead screw 38 to rotate. The rotation of the horizontal lead screw 38 drives the horizontal nut assembly to drive the horizontal moving block 39 to move along the horizontal guide rod 37. The horizontal moving block 39 drives the bottle winding belt assembly 31 on the support frame 29 to move in a direction closer to or away from the labeling channel 21, thereby adjusting the distance between the bottle winding belt assembly 31 and the labeling channel 21. The up-and-down servo motor 41 drives the up-and-down lead screw 42 to rotate. The rotation of the up-and-down lead screw 42 drives the up-and-down nut assembly 45 to drive the up-and-down moving block 44 to move along the up-and-down guide rod 43.

[0061] Refer to Figure 5 , Figure 5 The dotted line in [reference] is the walking route of the label. When feeding labels, label rolls are installed on the current unwinder 48 and the standby unwinder 49 respectively. The labels on the current unwinder 48 sequentially pass around the current label guiding roller group 51, the transition roller group 54, the laser coding position 55, and the buffer driving roller group 56 and then enter the buffer mechanism 57. At the laser coding position 55, the laser coder 60 codes the labels. The labels on the buffer mechanism 57 are sent to the label feeding roller group 62 via the label feeding roller group 58, and then sent from the label feeding roller group 62 to the peeling assembly 63. After the peeling assembly 63 separates the backing paper from the labels, the label winding belt assembly 31 pastes the labels on the packaging bottles, and the backing paper is collected on the winding roller group 64. During the working process, the current label detector 50 detects the remaining amount of the label roll on the current unwinder 48, and the standby label detector 52 detects the remaining amount of the label roll on the standby unwinder 49. When the current label detector 50 detects that the remaining amount of the label roll on the current unwinder 48 is insufficient, an alarm is given to remind to replace the label roll. Manually connect the label roll sent out by the current unwinder 48 to the label roll sent out by the standby unwinder 49. When connecting, pass the label roll on the standby unwinder 49 around the standby label guiding roller group 53, then around the transition roller group 54, and then connect it to the label on the transition roller group 54. When connecting, the buffer driving roller group 56 stops working and stops sending labels to the buffer mechanism 57. The label feeding roller group 58 continues to work and continues to send the labels buffered on the buffer mechanism 57 to the label feeding roller group 62. After the label rolls of the standby unwinder 49 and the current unwinder 48 are successfully connected, the walking route of the label roll on the standby roll feeder is the same as that of the label roll on the current unwinder 48. The standby label detector 52 detects the remaining amount of the label roll on the standby unwinder 49, and then installs a new label roll on the current unwinder 48, and so on. Thus, it is possible to replace the label roll without stopping the equipment, improving the work efficiency.

[0062] Refer to Figures 12 to 21, the three-dimensional buffer device 10 includes a mounting frame 65, a lifting transmission mechanism 66, a buffer conveyor belt 67, a conveying transmission mechanism 68, a discharging swing rod mechanism 69, and a discharging guiding mechanism 70. The lifting transmission mechanism 66 is arranged on the mounting frame 65. The buffer conveyor belt 67 has several layers, and the several layers of buffer conveyor belts 67 are spaced apart from top to bottom. And the several layers of buffer conveyor belts 67 are connected to the mounting frame 65 through a lifting guiding mechanism 71. Each adjacent two layers of buffer conveyor belts 67 are connected by a spacing plate 72. The lifting transmission mechanism 66 is connected to the buffer conveyor belt 67 at the top layer. The lifting transmission mechanism 66 is used to control any buffer conveyor belt 67 to lift to a position flush with the conveying line 1. The conveying transmission mechanism 68 is connected to a moving mechanism 73. The moving mechanism 73 controls the conveying transmission mechanism 68 to separate from or contact the buffer conveyor belt 67. The discharging swing rod mechanism 69 and the discharging guiding mechanism 70 are respectively located on both sides of the buffer conveyor belt 67.

[0063] In this embodiment, the buffer conveyor belt 67 is provided with four layers in total.

[0064] An electrical box 74 is arranged on the side wall of the mounting frame 65. A touch screen 75 is arranged above the electrical box 74. The touch screen 75 is connected to the mounting frame 65. The electrical box 74 is used for power supply. The touch screen 75 is used to control the operation of the lifting transmission mechanism 66, the conveying transmission mechanism 68, the discharging swing rod mechanism 69, and the discharging guiding mechanism 70.

[0065] A baffle 76 is arranged above the conveying line 1. The baffle 76 corresponds to the buffer conveyor belt 67. The baffle 76 is connected to a support arm 77. The support arm 77 is connected to a rotating rod 78. A connecting rod 79 is connected to the rotating rod 78. The connecting rod 79 is connected to the output end of a stockpiling air cylinder 80.

[0066] When buffering the packaging bottles from the conveying line 1 to the buffer conveyor belt 67, the lifting transmission mechanism 66 first controls one layer of the buffer conveyor belt 67 to lift to the same height as the conveying line 1. Then the conveying transmission mechanism 68 contacts the buffer conveyor belt 67 and transmits the power to the buffer conveyor belt 67 to make the buffer conveyor belt 67 rotate. The stockpiling air cylinder 80 drives the rotating rod 78 to rotate through the connecting rod 79. The rotating rod 78 drives the baffle 76 through the support arm 77 to dial the packaging bottles on the conveying line 1 onto the buffer conveyor belt 67, so as to realize storing the packaging bottles on the conveying line 1 onto the buffer conveyor belt 67. When the buffer conveyor belt 67 is full of packaging bottles, the conveying transmission mechanism 68 separates from the buffer conveyor belt 67. The lifting transmission mechanism 66 controls the next layer of the buffer conveyor belt 67 to lift to the same height as the conveying line 1. The next layer of the buffer conveyor belt 67 repeats the stockpiling action of the previous layer of the buffer conveyor belt 67. Repeat this cycle until all the buffer conveyor belts 67 are full of packaging bottles.

[0067] When there are missing packaging bottles on the conveyor line 1 or the incoming packaging bottles are reduced, the lifting and transmission mechanism 66 first controls the first-layer buffer conveyor belt 67 to lift to the same height as the conveyor line 1, and then controls the discharge guiding mechanism 70 to extend above the buffer conveyor belt 67. The conveying and transmission mechanism 68 contacts the buffer conveyor belt 67 to transmit power to the buffer conveyor belt 67. The buffer conveyor belt 67 rotates to send the packaging bottles thereon to the conveyor line 1. When the packaging bottles on the buffer conveyor belt 67 are about to finish feeding, the discharge swing rod mechanism 69 swings out to convey the tail materials on the buffer conveyor belt 67 to the conveyor line 1. Then, the discharge swing rod mechanism 69 and the discharge guiding mechanism 70 return to the origin, the conveying and transmission mechanism 68 is separated from the buffer conveyor belt 67, and the lifting and transmission mechanism 66 controls the next-layer buffer conveyor belt 67 to lift to the same height as the conveyor line 1. The next-layer buffer conveyor belt 67 repeats the feeding action of the previous-layer buffer conveyor belt 67. This cycle is repeated to send the packaging bottles on each layer of the buffer conveyor belt 67 to the conveyor line 1.

[0068] The lifting and transmission mechanism 66 includes a lifting servo motor 81, a chain and sprocket drive structure 82, a transmission lead screw 83, and a transmission nut assembly 84. The lifting servo motor 81 and the chain and sprocket drive structure 82 are respectively arranged at the top of the mounting frame 65. The output end of the lifting servo motor 81 is connected to the chain and sprocket drive structure 82. A total of four transmission lead screws 83 are provided. The four transmission lead screws 83 are distributed in a rectangular shape and are respectively connected to the chain and sprocket drive structure 82. Each transmission lead screw 83 is rotatably arranged on the mounting frame 65. A transmission nut assembly 84 is sleeved on each transmission lead screw 83. The side part of the buffer conveyor belt 67 at the top layer is fixedly connected to the transmission nut assembly 84 through a connecting member 85.

[0069] The chain and sprocket drive structure 82 includes a driving sprocket 86, four driven sprockets 87, and a transmission chain 88.

The transmission chain 88 is sleeved on the driving sprocket 86 and the four driven sprockets 87.

[0070] The lifting guiding mechanism 71 includes a guiding slide rail 89 and a guiding slider 90. The guiding slide rail 89 is arranged on the mounting frame 65, and the guiding slide rail 89 is parallel to the transmission lead screw 83. A connecting plate 91 is arranged on the side wall of the bracket 96 of each buffer conveyor belt 67. The connecting plate 91 is connected to the guiding slide rail 89 through the guiding slider 90. A spacing plate 72 is connected between every two adjacent connecting plates 91.

[0071] The spacing plate 72 is in a strip structure. A strip hole 93 is arranged on the spacing plate 72 along its length direction. Two adjacent connecting plates 91 are connected through the spacing plate 72, and one of the two adjacent connecting plates 91 can move along the length direction of the strip hole 93.

[0072] When the lifting transmission mechanism 66 drives the buffer conveyor belt 67 to lift, the lifting servo motor 81 drives the driving sprocket 86 to rotate. The driving sprocket 86 drives the driven sprocket 87 to rotate through the transmission chain 88. The driven sprocket 87 drives the transmission lead screw 83 to rotate. The rotating transmission lead screw 83 and the transmission nut assembly 84 interact to drive the connecting piece 85 to move along the transmission lead screw 83 with the transmission nut assembly 84. The transmission nut assembly 84 drives the connecting plate 91 on the side of the buffer conveyor belt 67 arranged on the top layer to move along the guiding slide rail 89. The buffer conveyor belt 67 on the top layer drives the connecting plate 91 on the adjacent buffer conveyor belt 67 to move along the guiding slide rail 89 through the spacing plate 72, and so on, thereby driving all the buffer conveyor belts 67 to lift. When driving the buffer conveyor belt 67 to lift, the connecting plate 91 moves along the length direction of the strip-shaped hole 93, thereby pulling open the distance between adjacent two layers of buffer conveyor belts 67, facilitating material storage and feeding.

[0073] The conveying transmission mechanism 68 includes a conveying servo motor 94, a transmission shaft 95, a bracket 96, and a chain and sprocket transmission structure 97.

[0075] The moving mechanism 73 includes a driving cylinder 102, a conveying slider 103, and a conveying slide rail 104. The conveying slide rail 104 is arranged on the top of the electric box 74. The conveying slider 103 is arranged on the conveying slide rail 104, and the conveying slider 103 is connected to the bottom of the bracket 96. The driving cylinder 102 is connected to the side wall of the bracket 96.

[0076] When the conveying drive mechanism 68 controls the rotation of the buffer conveyor belt 67, first, the driving cylinder 102 controls the support 96 to move along the conveying slide rail 104, driving the driving chain 101 to move towards the buffer conveyor belt 67, and meshing the driving chain 101 with the transmission sprocket 123. Then, the conveying servo motor 94 drives the transmission shaft 95 to drive the rotating shaft 98 to rotate. The rotating shaft 98 drives the main driving sprocket 99 to rotate. The main driving sprocket 99 drives the driving chain 101 and the driven driving sprocket 100 to rotate. The driving chain 101 rotates to drive the transmission sprocket 123 to rotate, thereby driving the buffer conveyor belt 67 to rotate. When separating the driving chain 101 from the transmission sprocket 123, the driving cylinder 102 controls the mounting bracket 65 to move along the conveying slide rail 104, driving the driving chain 101 to move away from the buffer conveyor belt 67, and separating the driving chain 101 from the transmission sprocket 123.

[0077] Referring to Figures 24 to 26 , the discharging guiding mechanism 70 includes a mounting base 105, a discharging cylinder 106, a driving rack 107, a driving gear 108, a rotating rod 109, a rotating seat 110, a guiding telescopic rod 111, and a guiding telescopic cylinder 112.

The output end of the guiding telescopic cylinder 112 is connected to the guiding telescopic rod 111 through a connecting block 11346.

[0078] When the materials on the conveying line 1 are lacking and the incoming materials are reduced, the discharging cylinder 106 controls the movement of the driving rack 107. The driving rack 107 drives the driving gear 108 to rotate. The driving gear 108 drives the rotating rod 109 to rotate. The rotating rod 109 drives the guiding telescopic rod 111 and the guiding telescopic cylinder 112 to rotate above the buffer conveyor belt 67 through the rotating seat 110. Then, the guiding telescopic cylinder 112 drives the guiding telescopic rod 111 to extend. The height of the buffer conveyor belt 67 is the same as that of the conveying line 1, and the buffer conveyor belt 67 rotates, thereby sending the materials on the buffer conveyor belt 67 to the conveying line 1.

The output end of the swing telescopic cylinder 120 is connected to the swing telescopic rod 119 through a fixing block 121.

[0080] When the buffer conveyor belt 67 is about to finish feeding, the swing rod cylinder 114 drives the swing rod 117 to swing through the swing arm 116. The swing rod 117 drives the swing telescopic rod 119 and the swing telescopic cylinder 120 to swing outwards from the side of the buffer conveyor belt 67 to above the end of the buffer conveyor belt 67 through the swing seat 118. The swing telescopic cylinder 120 drives the swing telescopic rod 119 to extend, and conveys the remaining tail material on the buffer conveyor belt 67 to the conveyor line 1. Then the swing telescopic cylinder 120 drives the swing telescopic rod 119 to retract. The swing rod cylinder 114 drives the swing rod 117 to swing through the swing arm 116. The swing rod 117 drives the swing telescopic rod 119 and the swing telescopic cylinder 120 to swing from the end of the buffer conveyor belt 67 to the side of the buffer conveyor belt 67 through the swing seat 118.
