Description

Technical Field

[0002] The production process of canned milk powder packaging generally includes laser coding and inspection of the inside of the milk powder can to prevent metal, glass and other debris from remaining inside the milk powder can. The conventional inspection method is X-ray inspection. In order to avoid long-term radiation of X-rays to the milk powder can, the milk powder can cannot be placed in the inspection device for a long time. Therefore, after the inspection of the milk powder can is completed, the milk powder can needs to be transported to the next process.

[0042] The present application is further described in detail below in conjunction with the accompanying drawings.

[0043] The embodiment of the present application discloses an intelligent packaging production line for canned milk powder.

[0044] Embodiment 1:

[0045] Reference Figure 1 The canned milk powder intelligent packaging production line includes a feeding component 1, which includes a conveyor belt 13. The conveyor belt 13 is a chain conveyor belt and runs through the entire production line. One end of the feeding component 1 is provided with a feeding screw 11 as an input end, and the other end is provided with a product channel 9 as an output end. The milk powder cans are transported to the conveyor belt 13 through the feeding screw 11.

[0046] Reference Figure 2 The canned milk powder intelligent packaging production line includes a coding device 2 and a detection device 3. The coding device 2 is mounted on the conveyor belt 13 near the feeding screw 11, and the detection device 3 is mounted on the conveyor belt 13 near the coding device 2. A can turning rack 12 is mounted between the detection device 3 and the coding device 2. The can turning rack 12 turns the milk powder can with the coding on the bottom 180 degrees. The turned milk powder can enters the detection device 3 for detection. An X-ray detector is provided in the detection device 3 to detect whether there are foreign objects in the milk powder can.

[0047] Reference Figure 2The canned milk powder intelligent packaging production line includes a waste channel 4, which is mounted at one end of the detection device 3 away from the coding device 2. The waste channel 4 is connected to the detection device 3 through a pipeline. Unqualified milk powder cans after detection by the detection device 3 are pushed into the waste channel 4 by the waste cylinder 41 provided in the detection device 3, and qualified milk powder cans are continuously transported to the next process via the conveyor belt 13.

[0048] Reference Figure 1 The canned milk powder intelligent packaging production line includes a buffer device 5, which is mounted on the feeding assembly 1 and located between the detection device 3 and the product channel 9. The buffer device 5 includes a buffer assembly 6, which includes a buffer platform 61, a buffer rod 63 and a buffer cylinder 62. The buffer platform 61 is mounted on the conveyor belt 13 near the detection device 3. The cylinder body of the buffer cylinder 62 is rotatably mounted on one side of the conveyor belt 13 near the buffer platform 61. One end of the buffer rod 63 is rotatably mounted on the conveyor belt 13 near the buffer cylinder 62, and the other end faces the buffer platform 61. Figure 3 One end of the cache rod 63 close to the cache cylinder 62 is rotatably connected to the piston rod of the cache cylinder, and the cache cylinder 62 drives the cache rod 63 to rotate in the horizontal direction.

[0049] Reference Figure 1 The cache component includes a sensor 64, which is mounted on the conveyor belt 13 between the cache platform 61 and the product channel 9. The sensor 64 is used to determine whether there is a can blockage on the conveyor belt 13 near the product channel 9. When the milk powder cans circulate and stagnate between various processes, the milk powder cans are easily retained and accumulated on the front conveyor belt, so that the milk powder cans block the transmission channels of the receiving and transmitting ends of the sensor 64. When the transmission channel is blocked by the milk powder cans for more than one second, the sensor 64 determines that there is a can blockage on the conveyor belt 13. The sensor 64 sends a signal to the upper computer, and the upper computer controls the cache cylinder 62 to drive the cache rod 63 to rotate toward the cache platform 61. At this time, the conveyor belt 13 continues to transport the milk powder cans, and the milk powder cans will be guided by the cache rod 63 into the cache platform 61, thereby emptying the milk powder cans in the detection device 3.

[0050] Reference Figure 4 and Figure 5The cache platform 61 includes a cache material plate 611 and a cache motor 612. The cache motor 612 is mounted on the side of the cache platform 61. A driving roller 614 is fixedly connected to its driving shaft. The driving roller 614 is mounted inside the cache platform 61. A plurality of guide rods are also mounted inside the cache platform 61. The cache material plate 611 is a plastic chain plate. The cache material plate 611 is mounted on the cache platform 61 through the driving roller 614 and the guide rod. The cache motor 612 drives the driving roller 614 to rotate, driving the cache material plate 611 to reciprocate on the cache platform 61, thereby driving the milk powder can to move on the cache platform 61 toward the conveyor belt 13.

[0051] Reference Figure 4 and Figure 5 , a guardrail is mounted on the edge of the buffer platform 61, and three sets of sensors 3 613 are mounted on the guardrail in the length direction of the buffer platform 61, of which two sets of sensors 3 613 are arranged at both ends of the buffer platform 61 along the length direction of the buffer platform 61, and the other set of sensors 3 613 is mounted on the diagonal of the length direction of the buffer platform 61. The buffer motor 612 drives the milk powder can to move back and forth on the buffer platform 61 through the buffer material plate 611 until the sensor 3 613 determines that there is no milk powder can left on the buffer platform 61. When the milk powder can is moved back and forth on the buffer platform 61, it continuously passes through the signal transmission channel of the sensor 3 613, and the sensor 63 sends a signal to the upper computer to determine that there is a milk powder can on the buffer platform 61. When no milk powder can passes through the signal transmission channel of the sensor 3 613, the sensor 3 613 determines that there is no milk powder can on the buffer platform 61.

[0052] The working principle of the embodiment of the present application is as follows: the milk powder can is transported to the conveyor belt 13 by the feeding screw 11, and after the coding device 2 codes the bottom of the milk powder can, it is transported to the can turning rack 12 by the conveyor belt 13, and the milk powder can is turned 180 degrees by the can turning rack 12. The conveyor belt 13 transports the turned milk powder can to the detection device 3 to detect the foreign matter in the milk powder can. If foreign matter is detected, the milk powder can containing the foreign matter is pushed into the waste channel 4 by the waste cylinder 41 arranged in the detection device 3; if no foreign matter is detected, the conveyor belt 13 continues to transport it to the next process.

[0053] When sensor 64 detects that there is congestion of milk powder cans on the conveyor belt 13 near the product channel 9, sensor 64 transmits a signal to the upper computer, and the upper computer controls the feeding screw 11 to stop feeding. At the same time, the buffer cylinder 62 drives the buffer rod 63 to rotate toward the buffer platform 61, and guides the milk powder cans transported from the detection device 3 to the buffer platform 61 through the buffer rod 63.

[0054] When sensor 1 64 determines that there is no congestion on the conveyor belt 13 near the product channel 9, sensor 1 64 sends a signal to the host computer, and the host computer controls the cache cylinder 62 to drive the cache rod 63 to rotate away from the cache platform 61. At the same time, the cache motor 612 drives the cache material plate 611 to move back and forth in the direction of the conveyor belt 13, and the milk powder cans on the cache platform 61 are delivered to the conveyor belt 13. The residual situation of the milk powder cans on the cache platform 61 is judged by sensor three 613. When all the milk powder cans on the cache platform 61 are transported to the conveyor belt 13, sensor three 613 sends a signal to the host computer, and the host computer controls the feeding screw 11 to perform the feeding work.

[0055] Embodiment 2:

[0056] Reference Figure 6 and Figure 7 The difference between this embodiment and the first embodiment is that the buffer device 5 includes a stacking assembly 7, and the stacking assembly 7 includes a lane-changing rod 72 and a lane-changing cylinder 73. The lane-changing rod 72 is rotatably installed on the conveyor belt 13 near the product channel 9, and the lane-changing cylinder 73 is rotatably installed on the conveyor belt 13 near the lane-changing rod 72. One end of the lane-changing rod 72 is rotatably connected to the piston rod of the lane-changing cylinder 73, and the other end faces the product channel 9. The lane-changing cylinder 73 guides the milk powder cans on the conveyor belt 13 to the product channel 9 by driving the lane-changing rod 72 to rotate horizontally toward the product channel 9.

[0057] Reference Figure 6 The cache component includes two sets of sensors 74 arranged along the length direction of the product channel 9, and the congestion of milk powder cans on the product channel 9 is determined by the sensors 74. When milk powder cans are circulated and stagnant between various processes, milk powder cans are easily accumulated on the front conveyor belt, so that the milk powder cans block the transmission channels of the receiving end and the transmitting end of the sensor 74. When the transmission channel is blocked by the milk powder cans for more than one second, the sensor 74 determines that there is a can jam on the conveyor belt 13.

[0058] Reference Figure 6 and Figure 8The buffer assembly includes a stacking platform 71, which is mounted near the product channel 9. The stacking platform 71 includes three layers of ascending channels 711 and three layers of descending channels 712. Chain plate conveyors are provided in the ascending channels 711 and the descending channels 712. The ascending channels 711 and the descending channels 712 are spirally mounted near the product channel 9. The lowest end of the ascending channel 711 is connected to the conveyor belt 13, and its highest end is connected to the highest end of the descending channel 712. The lowest end of the descending channel 712 is connected to the product channel 9. The milk powder cans are transported to the ascending channel 711 through the conveyor belt 13, and the milk powder cans are transported to the ascending channel 711 through the chain plate conveyor for stacking, and then the milk powder cans in the stacking platform 71 are transported to the product channel 9 through the descending channel 712.

[0059] Reference Figure 6 and Fig. 9 A blocking mechanism 8 is installed at the connection point between the descending channel 712 and the product channel 9. The blocking mechanism 8 includes a blocking column 82 and a blocking cylinder 83. The blocking column 82 is rotatably mounted on a mounting seat 86 on one side of the product channel 9. The mounting seat 86 is fixedly connected to a side of the product channel 9 close to the stacking platform 71. A plurality of blocking grooves 821 are opened on the outer wall of the blocking column 82 along the circumferential direction. The blocking cylinder 83 is fixedly mounted on the mounting seat 86 close to the blocking column 82, and the piston rod of the blocking cylinder 83 is engaged with the blocking groove 821.

[0060] Reference Fig. 9 and Fig.10 The blocking mechanism 8 also includes a blocking plate 81, a core shaft 84 and a bearing 85. The blocking plate 81 is a star wheel structure, which is fixedly connected to the blocking column 82 through the core shaft 84. The blocking column 82 is sleeved with a bearing 85, and the blocking column 82 is rotatably connected to the mounting seat 86 through the bearing 85. Figure 6 and Fig. 9 When the blocking cylinder 83 is started, its piston rod is separated from the blocking groove 821, and the blocking plate 81 contacts the milk powder can. The milk powder can drives the blocking plate 81 to rotate under the drive of the conveyor belt 13, thereby driving the blocking column 82 to rotate, so that the milk powder can enters the product channel 9.

[0061] The working principle of the embodiment of the present application is as follows: the milk powder can is transported to the conveyor belt 13 by the feeding screw 11, and after the coding device 2 codes the bottom of the milk powder can, it is transported to the can turning rack 12 by the conveyor belt 13, and the milk powder can is turned 180 degrees by the can turning rack 12, and the conveyor belt 13 transports the turned milk powder can to the detection device 3 to detect the foreign matter in the milk powder can. If foreign matter is detected, the milk powder can containing the foreign matter is pushed into the waste channel 4 by the waste cylinder 41 arranged in the detection device 3; if no foreign matter is detected, the conveyor belt 13 continues to transport it to the product channel 9.

[0062] When sensor 2 74 detects that there is congestion of milk powder cans in the product channel 9, sensor 2 74 sends a signal to the upper computer, and the upper computer controls the feeding screw 11 to stop feeding, and at the same time controls the lane changing cylinder 73 to drive the lane changing rod 72 to rotate away from the product channel 9, so that the milk powder cans are transported to the stacking platform 71 through the conveyor belt 13, and the milk powder cans are transported to the ascending channel 711 and the descending channel 712 through the chain conveyor belt, and all the milk powder cans located in the detection device 3 are transported to the stacking platform 71. At this time, the piston rod of the blocking cylinder 83 is engaged with the blocking groove 821 on the blocking column 82, preventing the milk powder cans in the stacking platform 71 from entering the product channel 9.

[0063] When sensor 2 74 detects that there is no congestion in product channel 9, sensor 2 74 sends a signal to the upper computer, and the upper computer controls the blocking cylinder 83 to start, so that the piston rod of the blocking cylinder 83 is separated from the blocking groove 821 on the blocking column 82, and the milk powder can is driven by the chain conveyor belt and collides with the blocking plate 81, thereby driving the blocking column 82 to rotate, so that the milk powder can enters the product channel 9. After that, the upper computer controls the feeding screw 11 to feed the milk powder can, and at the same time, the upper computer controls the lane changing cylinder 73 to drive the lane changing rod 72 to rotate toward the direction of the product channel 9, so that the milk powder can on the conveyor belt 13 directly enters the product channel 9.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
