Description

Technical Field

[0001] The invention belongs to the field of case packing equipment, and in particular relates to a multi-standard case packing machine. Background Art

[0002] With the continuous expansion of automation in the packaging of alcoholic beverages, condiments and edible oils, the specifications of bottles sold at the terminal have become diverse. Existing technologies mostly rely on manual intervention to adjust to different specifications. When a production line needs to pack bottles of multiple specifications, it needs to stop production for a period of time, manually adjust the mechanism, and replace the corresponding parts of bottles of different specifications. This method is time-consuming and inefficient. Some automatically adjusted packing mechanisms can often only adjust the distance between bottles, but cannot adjust the longitudinal distance between bottles in the box, nor can they adjust the distance between boxes, and cannot achieve stepless adjustment, which often leads to a decrease in the production capacity of the entire line and low efficiency after changing the specifications.

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] like Figure 1-7As shown, a multi-standard case packing machine includes a frame 10, which is a rectangular parallelepiped frame. A bottle feeding mechanism 3 and a box conveying mechanism 5 are installed side by side at the bottom of the frame 10. A box guide mechanism 4 is provided just above the box conveying mechanism 5. The box guide mechanism 4 is slidably installed on the inner side of the frame 10, and the box guide mechanism 4 can move up and down along the frame 10. A transplanting mechanism 2 is installed on the top of the frame 10. A bottle grabbing mechanism 1 is fixedly installed at the bottom of the transplanting mechanism 2. The bottle grabbing mechanism 1 is located inside the frame 10. The transplanting mechanism 2 can drive the bottle grabbing mechanism 1 to move in the horizontal and vertical directions. The bottle grabbing mechanism 1 includes a connecting beam 11, which is fixed to the transplanting mechanism 2. A slide rail 12 is fixedly installed at the bottom of the connecting beam 11. The slide rail 12 is provided with two, and the two slide rails 12 are arranged in parallel at the bottom of the connecting beam 11. A series screw rod 16 is also rotatably installed at the bottom of the connecting beam 11. The connecting rod 16 is arranged between the two slide rails 12, and a plurality of bottle clamping units 13 are slidably installed on the slide rails 12. The bottle clamping units 13 are located below the connecting beam 11. A first connecting rod 14 is rotatably installed on an outer end surface of the connecting beam 11. The first connecting rod 14 is connected to the second connecting rod 15 through a hinge 6, wherein the hinge 6 is composed of two hinged arms rotatably installed together, the first connecting rod 14 is fixedly connected to the hinge 6, and a first motor 111 and a second motor 112 are fixedly installed on the top of the connecting beam 11. The first motor 111 forms a transmission connection relationship with the first connecting rod 14 through a first synchronous belt set 61. The first synchronous belt set 61 consists of a synchronous belt and a pulley driving the synchronous belt. This is a general structure of belt drive and will not be further described. The second motor 112 forms a transmission connection relationship with the series screw rod 16 through the second synchronous belt 62 through a through hole provided on the connecting beam 11;

[0046] In this embodiment, two bottle clamping units 13 form a group, and the bottles grasped by one group of bottle clamping units 13 can load a box, and the series screw rod 16 is threadedly connected to the bottle clamping unit 13;

[0047] The bottle clamping unit 13 includes a mounting plate 131, on the top plate surface of the mounting plate 131, a movable slider 132 matching the slide rail 12 is fixedly mounted, and the movable slider 132 is slidably connected to the slide rail 12, two supports 133 are fixedly mounted on both sides of the bottom plate surface of the mounting plate 131, and a guide rod 136 is fixedly connected between the two supports 133, and a first slider 134 and a second slider 135 are sleeved on the guide rod 136, and the first slider 134 is fixedly connected to the guide rod 136, and the second slider 135 is slidably connected to the guide rod 136, and the second slider 134 is fixedly connected to the guide rod 136, and the second slider 135 is slidably connected to the guide rod 136. A sleeve 137 is fixed at the top of the second connecting rod 15, and the sleeve 137 is slidably mounted on the second connecting rod 15. A gripper 139 is mounted on the lower ends of the first slider 134 and the second slider 135. A threaded seat 138 is fixed at the lower end of the mounting plate 131. The threaded seat 138 is arranged between the two supports 133. A lead screw telescopic adjustment rod 17 is screwed into the screw hole of the threaded seat 138. One end of the lead screw telescopic adjustment rod 17 is transmission-connected to the third motor 113 arranged on the side of the connecting beam 11. The gripper 139 can grasp bottles with a diameter range of 135 to 150 mm.

[0048] The lead screw telescopic adjustment rod 17 is composed of a plurality of alternately connected opposing adjustment lead screws 171 and telescopic shafts 172. Adjacent opposing adjustment lead screws 171 and telescopic shafts 172 are fixedly connected by a coupling 173. Each opposing adjustment lead screw 171 is provided with symmetrical positive and negative threads. Each opposing adjustment lead screw 171 is screwed with two threaded seats 138 through positive and negative threads, thereby realizing the opposing movement of the two bottle clamping units 13 at the bottom of the two threaded seats 138. The lead screw telescopic adjustment rod 17 is driven by the third motor 113 to rotate. At this time, the telescopic shaft 172 does not extend or retract. The telescopic shaft 172 serves as a rotating transmission shaft between the two opposing adjustment lead screws 171, so that each opposing adjustment lead screw 171 rotates synchronously, so that the two adjacent bottle clamping units 13 are moved closer or farther away from each other, thereby realizing the lateral movement between the bottles.

[0049] A first sensor group 7 is provided on the connecting beam 11 extending outward. The first sensor group 7 is mainly used to prevent the first connecting rod 14 from rotating at an angle exceeding a threshold range. A plurality of horizontally arranged photoelectric sensors are provided on the first sensor group 7. A sensor strip 71 matching the first sensor group 7 is fixedly installed on the rod body of the first connecting rod 14. When the first connecting rod 14 drives the sensor strip 71 to rotate to the edge position of the first sensor group 7 (i.e., the outermost photoelectric sensor), the first motor 111 stops moving. The two articulated arms of the hinge 6 are provided with a certain angle. When the first motor 111 drives the first connecting rod 14 to rotate, the first connecting rod 14 drives the two articulated arms to change, thereby driving the second connecting rod 15 to drive the second slider 135 to slide on the guide rod 136, thereby adjusting the distance between the bottle clamping unit 13 at the bottom of the second slider 135 and the bottle clamping unit 13 at the bottom of the first slider 134.

[0050] In this embodiment, the two groups of bottle clamping units 13 on the same opposing adjustment screw rod 171 are a spacing bottle clamping group, the second motor 112 drives the series screw rod 16 to rotate, and the series screw rod 16 drives the two adjacent spacing bottle clamping groups to move in opposite directions. At this time, the telescopic shaft 172 between the two adjacent spacing bottle clamping groups performs telescopic movement.

[0051] like Figure 9-14 As shown, the transplanting mechanism 2 includes a track base plate 21, which is fixed on the upper end of the frame 10 and perpendicular to the guide box mechanism 4. Two parallel translation guide rails 22 are fixedly installed on the top plate surface of the track base plate 21. The other two sides of the upper end of the track base plate 21 are respectively provided with a translation synchronous wheel 23 and a translation motor 24. The translation synchronous wheel 23 is connected to the translation driving wheel at the end of the rotor shaft of the translation motor 24 through the third synchronous belt 63. A lifting and fixing frame 25 is slidably installed on the translation guide rail 22. The lifting and fixing frame 25 is a strip frame body. Vertically arranged lifting cylinders 28 are fixedly installed at both ends of the lifting and fixing frame 25 through a cylinder frame. A belt through hole is provided on the lifting and fixing frame 25. A translation toothed belt meshing member 211 is fixedly installed at the edge of the through hole. The third synchronous belt 63 is connected to the translation driving wheel at the end of the rotor shaft of the translation motor 24. The synchronous belt 63 is connected through the belt through hole and meshed with the translation toothed belt meshing member 211. A lifting drive mechanism 27 is installed at the middle of the top of the lifting fixed frame 25. The lifting fixed frame 25 is provided with lifting guide rails 26 vertically slidably disposed on both sides of the lifting drive mechanism 27. The bottom end of the lifting guide rails 26 is fixedly connected to the bottle grabbing mechanism 1. The bottle grabbing mechanism 1 is located below the track bottom plate 21. The end of the piston rod in the cylinder of the lifting cylinder 28 extends to the bottom of the lifting fixed frame 25 and is fixedly connected to the bottle grabbing mechanism 1. Synchronous belt fixing seats 212 are fixed to the inner side surfaces of the upper and lower ends of the lifting guide rails 26. A fifth synchronous belt 65 is fixed between the two synchronous belt fixing seats 212. The lifting drive mechanism 27 drives the fifth synchronous belt 65 to lift and lower the lifting guide rails 26 on both sides.

[0052] The translation motor 24 drives the lifting and fixing frame 25 to slide along the translation guide rail 22 through the third synchronous belt 63, thereby driving the bottle grabbing mechanism 1 to move horizontally to above the box guide mechanism 4;

[0053] The lifting drive mechanism 27 and the lifting cylinder 28 synchronously drive the lifting guide rail 26 to move up and down. The lifting drive mechanism 27 drives the lifting guide rail 26 to move up and down through the fifth synchronous belt 65, thereby driving the bottle grabbing mechanism 1 to move up and down. At the same time, the lifting cylinder 28 drives the lifting guide rail 26 to move up and down through telescoping, thereby driving the bottle grabbing mechanism 1 to move up and down.

[0054] The lifting drive mechanism 27 includes a lifting motor 221, a lifting shaft 222, and a bearing seat 223. The lifting motor 221 is fixed to the lifting fixed frame 25. Two bearing seats 223 are rotatably installed on the shaft body of the lifting shaft 222 through bearings. The bearing seats 223 are fixed to the lifting fixed frame 25. Lifting synchronous wheels 225 are fixedly installed at both ends of the lifting shaft 222. An intermediate synchronous wheel 224 is fixedly sleeved on the shaft body of the lifting shaft 222 located between the two bearing seats 223. The lower ends of the two bearing seats 223 are fixedly provided with tensioning wheels 225. 26. A lifting motor synchronous wheel is installed at the power output end of the lifting motor 221. The lifting motor synchronous wheel is connected to the intermediate synchronous wheel 224 through the fourth synchronous belt 64. The fifth synchronous belt 65 is connected to the tensioning wheel 226 and the lifting synchronous wheel 225 in turn to form an N-shaped connection structure, wherein the fifth synchronous belt 65 is meshed with the lifting synchronous wheel 225. The lifting motor 221 drives the lifting shaft 222 to rotate, so that the tensioning wheel 226 and the lifting synchronous wheel 225 drive the lifting guide rail 26 to perform lifting movement through the fifth synchronous belt 65.

[0055] In this embodiment, the use of the lifting motor 221 and the lifting cylinder 28 as two driving mechanisms to provide power simultaneously can not only increase the load-bearing capacity of the bottle grabbing mechanism 1 and increase the upper limit of the number of bottles it can grab, but also increase the stability during the bottle grabbing and moving process.

[0056] In this embodiment, the tandem screw 16 includes a multi-threaded screw 161 and a fixed seat 162. Both ends of the multi-threaded screw 161 are rotatably connected to the fixed seat 162. The tandem screw 16 is fixed to the lower end of the connecting beam 11 through the fixed seat 162 and is located between the two slide rails 12. A plurality of spacing movable screw seats 163 are screwed on the multi-threaded screw 161. The multi-threaded screw 161 is provided with a plurality of groups of opposing threads, which are composed of right-handed threads and left-handed threads symmetrical to the right-handed threads. Two movable rotary seats 163 are connected, and one movable rotary seat 163 is fixedly matched with any one of the two bottle clamping units 13 on the same opposing adjustment screw 171, so that the adjacent spacing movable rotary seats 163 drive the bottle clamping units 13 on the two adjacent opposing adjustment screws 171 to make relative movement. A screw synchronous wheel 164 is fixedly provided in the middle of the multi-head screw 161, and the screw synchronous wheel 164 is transmission-connected to the second motor synchronous wheel at the end of the rotor shaft of the second motor 112 through the second synchronous belt 62.

[0057] The bottle feeding mechanism 3 includes a transmission platform 31, and an adjusting mechanism 32 is installed on the outer side of the transmission platform 31. The bottle feeding end and the bottle outlet end of the transmission platform 31 are respectively provided with a bottle blocking mechanism 35 and a bottle pressing mechanism 36. The bottle pressing mechanism 36 is located at the bottle feeding end of the transmission platform 31. A full bottle detection mechanism 34 is installed on the adjusting mechanism 32. Three parallel and equidistant channel partitions 33 are provided on the conveyor belt of the transmission platform 31. The three channel partitions 33 separate the transmission platform 31 into two transmission channels. The adjusting mechanism 32 adjusts the size of the transmission channel by adjusting the spacing between the channel partitions 33 to adapt to bottles of different sizes. The structure and principle of the adjusting mechanism 32 and the full bottle detection mechanism 34 have been recorded in the patent application with patent application number 202122499810.4 and will not be repeated here.

[0058] The bottle blocking mechanism 35 comprises a bottle blocking bracket 351 disposed above the transmission platform 31 , on which two baffles 352 are slidably mounted, each baffle 352 correspondingly blocks a transmission channel, and a bottle blocking driving motor 353 is disposed on the transmission platform 31 .

The bottle blocking screw bracket 356 is fixed to the transmission platform 31. The bottle blocking drive motor 353 is connected to the bottle blocking screw 354 through the bottle blocking drive wheel belt assembly. The bottle blocking drive motor 353 drives the bottle blocking screw 354 to rotate, and the bottle blocking screw 354 drives the bottle blocking bracket 351 to move back and forth along the transmission platform 31 through the sliding seat 355, so that the baffle 352 moves back and forth in the transmission channel.

[0060] In this embodiment, second sensors 8 are provided at the upper and lower ends of the lifting guide rail 26. The second sensors 8 are photoelectric sensors. When the spacing between the second sensors 8 is adjusted to adjust the maximum lifting distance of the lifting guide rail 26, the second sensors 8 generally do not work and only work when the lifting guide rail 26 exceeds the maximum lifting distance.

[0062] like Fig.15As shown, the guide box mechanism 4 includes a guide box lifting mechanism 41, a guide box rack 42 and a guide box frame 43. The guide box lifting mechanism 41 is fixed to the inner side of the frame 10, and the guide box frame 42 is arranged on the guide box lifting mechanism 41. The guide box lifting mechanism 41 can drive the guide box frame 43 to perform lifting movements. The guide box frames 43 are arrayed on the guide box frame 42. In this embodiment, in order to adapt to different boxes, the guide box frame 43 is fixed to the mounting groove 44 on the guide box rack 42 by screws, and the guide box frame 43 can be replaced by only pulling out the screws.
