Description

Technical Field

[0001] The utility model belongs to the technical field of automatic packaging, and in particular relates to an automatic tray-changing packaging machine. Background Art

[0002] Products need to be plated and packaged during the production process.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0037] Reference Figures 1 to 10The automatic tray-changing packaging machine of this embodiment includes a first hopper mechanism 1, a shift mechanism 2, a second hopper mechanism 3, and a plurality of spaced-apart third support frames 4 located below the first hopper mechanism 1, the shift mechanism 2, and the second hopper mechanism 3 for securing the three mechanisms to the ground. The first hopper mechanism 1 and the second hopper mechanism 3 are located at either end of the shift mechanism 2. The first hopper mechanism 1 is used to store a plurality of first packaging trays 14 and continuously provide first packaging trays 14 to the shift mechanism 2. The second hopper mechanism 3 is used to store a plurality of second packaging trays 33 and continuously receive a newly filled packaging tray transferred from the shift mechanism 2. The first packaging tray 14 is an empty tray, and the second packaging tray 33 is a full tray containing packaged products, i.e., the first packaging tray 14 is fully packed with products.

[0038] Specifically, if Figures 1 to 4 As shown, the first storage mechanism 1 includes a first flow channel 11, a first storage bin 12 for stacking a plurality of first packaging trays 14, and a blanking assembly 13 symmetrically arranged on both sides of the first storage bin 12. A gap is formed between the sides of two adjacent first packaging trays 14 in the first storage bin 12. The first flow channel 11 is located at the bottom of the first storage bin 12 and includes two symmetrically arranged first crossbars 111 and first and second crossbars 113 located at the top ends of the first crossbars 111. A groove 1111 is defined in the middle of the side of the first crossbar 111 near the blanking assembly 13. The bottom surface of the first protrusion 112 is fixedly connected to the top surface of the first cross bar 111, and the top surface of the first protrusion 112 is fixedly connected to the bottom surface of the second protrusion 113.

The side of the first cross bar 111 close to the blanking component 13 is flush with the side of the first protrusion 112 and the second protrusion 113 close to the blanking component 13. The side of the first cross bar 111 away from the blanking component 13 is flush with the side of the first protrusion 112 away from the blanking component 13. The width of the second protrusion 113 is smaller than the width of the first protrusion 112, and the length of the second protrusion 113 is equal to the length of the first protrusion 112. A step is formed between the top surface of the first protrusion 112 and the second protrusion 113 on the side away from the blanking component 13, and the distance between the two corresponding first protrusions 112 on the two first cross bars 111 is smaller than the width of the first packaging tray 14. The second protrusion 113 is in contact with the side of a first packaging tray 14 located in the first flow channel 11 on the side away from the blanking component 13. The first cross bars 111 on both sides of the bottom of the first storage bin 12 and the corresponding settings of the first protrusions 112 and the second protrusions 113 thereon are used to form a first flow channel 11 for transmitting the first packaging tray 14, and at the same time, the first packaging tray 14 can be limited along its width direction to prevent displacement or falling.

[0039] The unloading assembly 13 is used to unload a first packaging tray 14 at the bottom layer of multiple first packaging trays 14 stacked in the first storage bin 12 and place it on the first flow channel 11. Each unloading assembly 13 includes a first fixed plate 1311, a second fixed plate 1312, first fixed blocks 132 symmetrically arranged at both ends of the second fixed plate 1312, a connecting rod slidably connected to each first fixed block 132, an insert block 134 fixedly connected to one end of each connecting rod, and a first driver 1351 connected to the first fixed plate 1311. First support frames 136 are fixedly provided at both ends of the first fixed plate 1311, and the bottom of the first support frame 136 is fixed to the ground to ensure the stability of the entire unloading assembly 13; a first fixed block 132 is slidably connected to one end of the second fixed plate 1312.

The telescopic shaft of the first driver 1351 is fixedly connected to the second fixed plate 1312. The second fixed plate 1312 is located above the first fixed plate 1311.

[0040] The connecting rod includes a first rod portion 1331 and a second rod portion 1332 perpendicularly connected to the first rod portion 1331. An insert 134 is fixedly connected to the end of the second rod portion 1332 away from the first rod portion 1331. A third fixing plate 1313 is fixedly mounted on the end of the first rod portion 1331 away from the second rod portion 1332. Each first fixing block 132 has a through slot extending through its length, through which the second rod portion 1332 passes. A limiting rod 138 is fixedly mounted on the third fixing plate 1313, with one end of the limiting rod 138 facing the end of the first fixing block 132 away from the insert 134. A second actuator 1352 is also mounted on the first fixing block 132. The housing of the second actuator 1352 is fixedly connected to the first fixing block 132, and one end of the telescopic shaft of the second actuator 1352 is fixedly connected to the third fixing plate 1313. The length of the insert block 134 is perpendicular to the length of the first flow channel 11. The thickness of the end of the insert block 134 away from the second rod portion 1332 is less than the gap. The end of the insert block 134 away from the second rod portion 1332 can be inserted into the gap between two adjacent first packaging trays 14, thereby supporting the multiple first packaging trays 14 in the first storage bin 12 and preventing them from falling. In this embodiment, the first driver 1351 is used to drive the second fixing plate 1312 to move up and down in the vertical direction, thereby driving the first fixing block 132 and the connecting rod to move upward, and ultimately driving the two insert blocks 134 to move up and down, thereby driving the multiple first packaging trays 14 supported on the insert blocks 134 to move up and down in the vertical direction. The second driver 1352 then drives the third fixing plate 1313 to move forward and backward in a direction toward and / or away from the first storage bin 12, thereby driving the insert block 134 to move forward and backward in a direction toward and / or away from the first storage bin 12, thereby allowing the insert block 134 to be inserted into or removed from the gap between two adjacent first packaging trays 14.

[0041] Each blanking assembly 13 also includes a fourth fixed plate 1314, a support rod fixedly connected to one side of the fourth fixed plate 1314, a third driver 1353 connected to the fourth fixed plate 1314, and a first baffle 17 fixedly connected to the bottom of the first cross bar 111.

The shell of the third driver 1353 is fixedly connected to the side of the first baffle 17 away from the first flow channel 11, and the third driver 1353 is located between the first baffle 17 and the first driver 1351. The fifth fixed plate 1315 is located below the fourth fixed plate 1314. The groove 1111 on the first cross bar 111 is used for the fifth fixed plate 1315 to pass through, so as to avoid interference or obstruction to the up and down movement of the fifth fixed plate 1315. The third driver 1353 is used to drive the fourth fixed plate 1314 to move up and down in the vertical direction. The length direction of the support rod is parallel to the length direction of the first flow channel 11. The third driver 1353 is used to drive the fifth fixed plate 1315 to move up and down in the vertical direction, thereby driving the fourth fixed plate 1314 and the support rod to move up and down in the vertical direction.

[0042] Furthermore, the length of the support rod is greater than the length of the groove 1111, and the distance between the two second protrusions 113 on a first crossbar 111 is greater than the length of the support rod. The support rod includes a rod body 1391 and an extension 1392 fixedly disposed on the side of the rod body 1391 away from the third driver 1353. The bottom surface of the rod body 1391 is flush with the bottom surface of the extension 1392. The side of the second protrusion 113 away from the blanking assembly 13 is flush with the side of the rod body 1391 near the extension 1392. The first packaging tray 14 at the bottom layer of the first storage bin 12 is always located on the top surface of the extension 1392 of the support rod to be supported by the support rod, while also limiting the position of the first packaging tray 14 along its width. The top surface of the rod body 1391 is located above the top surface of the extension part 1392, and the height of the extension part 1392 is less than or equal to the height of the first protrusion 112, so as to ensure that the bottom surface of a first packaging plate 14 located on the extension part 1392 of the support rod can be just placed on the top surface of the first protrusion 112 to smoothly enter the first flow channel 11.

[0043] In this embodiment, a third support frame 4 is provided at each end of the bottom of the two first crossbars 111 of the first flow channel 11 to support and secure the entire first storage mechanism 1. Furthermore, a first cover plate 15 is fixedly provided on the side of each of the two blanking assemblies 13 away from the first flow channel 11 to protect the various components within the blanking assemblies 13 from being exposed and damaged. Furthermore, a second cover plate 16 is fixedly provided on the end of the first flow channel 11 away from the shifting mechanism 2.

[0044] like Figure 3and Figure 4 As shown, the shift mechanism 2 includes a second flow channel 21, a transmission assembly 22 and a pusher assembly 23 connected to the transmission assembly 22, the first flow channel 11 is connected to the second flow channel 21 and the first flow channel 11 and the second flow channel 21 are both located in the same horizontal direction, wherein the second flow channel 21 includes two symmetrically arranged second cross bars and a third protrusion 212 located on the top surface of the second cross bar 211, the second cross bar 211 and the third protrusion 212 are equal in length and the end of the second cross bar 211 is flush with the end of the third protrusion 212, the second cross bar 21 1 is greater than the width of the third protrusion 212, the outer side surface of the second cross bar 211 is flush with the outer side surface of the corresponding third protrusion 212, the top surface of the third protrusion 212 is flush with the top surface of the second protrusion 113, the top surface of the second cross bar 211 is flush with the top surface of the first protrusion 112, and one end of the second cross bar 211 and the third protrusion 212 is fixedly connected to one end of the first cross bar 111, the first protrusion 112 and the second protrusion 113 located on the same side, ensuring seamless connection between the first flow channel 11 and the second flow channel 21. In addition, three third support frames 4 are spaced apart at the bottom of the two second cross bars 211 of the second flow channel 21 to support and fix the shift mechanism 2 and the second storage mechanism 3. A second baffle 5 is fixedly installed between the three third support frames 4 on the same side, and a third baffle 6 is fixedly installed between the two third support frames 4 on the end of the two second cross bars 211 away from the first flow channel 11. The second baffle 5 and the third baffle 6 are used to protect and shield the components at the bottom of the second flow channel 21. A third cover plate 24 is fixedly installed on the top surface of the end of the third protrusion 212 away from the first storage mechanism 1 to limit the second packaging tray 33 transmitted on the second flow channel 21 in the vertical direction.

[0045] Specifically, the transmission assembly 22 includes a fixed frame 227, a fourth driver 222 connected to the fixed frame 227, screw rods 225 fixedly arranged on both sides of one end of the fixed frame 227, a transmission shaft 223 connected to the fourth driver 222, a slider 224 rotatably connected to the transmission shaft 223, a connecting plate 221 fixedly connected to one side of the slider 224, and a slide plate 226 fixedly connected to the inner sides of two third support rods at the bottom of a first cross bar 111. One side of the fixed frame 227 is fixedly connected to the slide plate 226, the housing of the fourth driver 222 is fixedly connected to the fixed frame 227, the transmission shaft 223 passes through the fixed frame 227, the transmission shaft 223 is parallel to the two screw rods 225, and the length of the transmission shaft 223 is equal to the length of the screw rods 225. The length direction of the screw rods 225 and the transmission shaft 223 are also parallel to the length direction of the first flow channel 11 and the second flow channel 21. The slider 224 is also slidably connected to two screw rods 225 on either side, one of which is located between the slider 224 and the connecting plate 221. The pusher assembly 23 is fixedly connected to the side of the connecting plate 221 away from the slider 224. The fourth driver 222 drives the transmission shaft 223 to rotate, driving the slider 224 to slide on the screw rods 225 along the length of the transmission shaft 223, thereby driving the connecting plate 221 to move, and ultimately driving the pusher assembly 23 located on the connecting plate 221 to move. The second cover plate 16 is provided to protect and shield the parts of the transmission assembly 22 located below the first flow channel 11.

[0046] In this embodiment, two pusher assemblies 23 are provided, and the two pusher assemblies 23 are respectively located at both ends of the connecting plate 221. Each pusher assembly 23 includes a push rod 231, a push rod driver 232, a second fixing block 233, a third fixing block 234, a sixth fixing plate 235, and an inserting rod 236. One side of the second fixing block 233 is fixedly connected to one side of the connecting plate 221, and the third fixing block 234 is located at the end of the second fixing block 233 away from the push rod 231. The housing of the push rod driver 232 is fixedly connected to the second fixing block 233, and one end of the telescopic shaft of the push rod driver 232 is fixedly connected to one end of the third fixing block 234. The second fixed block 233 is also provided with a sliding groove running through its length direction for the insertion rod 236 to pass through. The thickness of the insertion rod 236 is equal to the depth of the sliding groove. The insertion rod 236 can move up and down in the vertical direction relative to the second fixed plate 1312; one end of the insertion rod 236 is fixedly connected to the push rod 231, and the other end of the insertion rod 236 is fixedly connected to the other end of the third fixed block 234. The length of the insertion rod 236 is greater than the length of the second fixed block 233, and one side of the sixth fixed plate 235 is away from the second fixed block 233. One side of the connecting plate 221 is fixedly connected to ensure that the insertion rod 236 will not fall out of the slide groove. The push rod driver 232 is used to drive the third fixed block 234 to move up and down in the vertical direction, thereby driving the insertion rod 236 to move up and down in the slide groove, and finally driving the push rod 231 to move up and down in the vertical direction to ensure that the push rod 231 is raised when the push rod 231 is needed to push the packaging tray; when the moving path of the packaging tray is blocked, the push rod 231 can be lowered to ensure the unobstructed flow of the first flow channel 11 and the second flow channel 21. The length direction of the push rod 231 is perpendicular to the length direction of the first flow channel 11 and the second flow channel 21. The length of the push rod 231 is less than the width of the first packaging tray 14 and the second packaging tray 33. The distance between the two push rods 231 is greater than the length of the first packaging tray 14 and the second packaging tray 33, so as to ensure that the two push rods 231 on a connecting plate 221 can push a first packaging tray 14 on the first flow channel 11 to move toward the second flow channel 21, and at the same time push a first packaging tray 14 being packaged on the second flow channel 21 to continue to move along the second flow channel 21 toward the second storage bin 31 (such as Figure 2 to avoid downtime for disk replacement.

[0047] like Figures 5 to 10As shown, the second storage mechanism 3 includes a second storage bin 31 for stacking a plurality of second packaging trays 33 and jacking assemblies 32 symmetrically arranged on both sides of the second storage bin 31. A portion of the second flow channel 21 is located at the bottom of the second storage bin 31, that is, the bottom of the second storage bin 31 is fixedly connected to the second cross bar 211 and the third protrusion 212. Specifically, the jacking assembly 32 is used to lift a second packaging tray 33 located on the second flow channel 21 and below the second storage bin 31 upward to place it in the second storage bin 31. Each jacking assembly 32 includes a jacking driver 326, a first top plate 3271, and a second top plate 3272. The housing of the jacking driver 326 is fixedly connected to the first top plate 3271, and the telescopic shaft of the jacking driver 326 is fixedly connected to the second top plate 3272. The second top plate 3272 is located above the first top plate 3271, and the second top plate 3272 is located below the second storage bin 31. Two second support frames 329, a plurality of second guide sleeves 3281, and second guide posts 3282 slidably connected to the second guide sleeves 3281 are also fixedly mounted on the first top plate 3271. One end of the second guide post 3282 is fixedly connected to the second top plate 3272, and the top of the second support frame 329 is fixedly connected to the first top plate 3271. The widths of the first and second top plates 3271 and 3272 are both smaller than the widths of the first and second packaging trays 14 and 33. When fully packed packaging trays need to be stacked into the second storage bin 31, the lifting driver 326 is used to move the second top plate 3272 upward in the vertical direction, thereby moving a second packaging tray 33 located on the second flow channel 21 upward.

[0048] The lifting assembly 32 also includes a bracket 321, a lifting block 322, and a fourth fixing block 323. In this embodiment, two fourth fixing blocks 323 are spaced apart on each of the two third protrusions 212, and the fourth fixing blocks 323 on the two third protrusions 212 are symmetrically arranged. Each fourth fixing block 323 is fixedly connected to the third protrusion 212 via a bracket 321. Each fourth fixing block 323 is sequentially provided with a first receiving groove 3231 and a second receiving groove 3232 from one side near the second storage bin 31 to the other side. The first receiving groove 3231 is connected to the second receiving groove 3232. The first receiving groove 3231 is close to the second storage bin 31. The first receiving groove 3231 and the second receiving groove 3232 jointly extend through the width direction of the fourth fixing block 323. The top surface of the first receiving groove 3231 is flush with the top surface of the fourth fixing block 323. The height of the first receiving groove 3231 is greater than the height of the second receiving groove 3232 and less than the height of the fourth fixing block 323.

[0049] A portion of the top block 322 is located in the first accommodating groove 3231 and the second accommodating groove 3232, and the remaining portion of the top block 322 is located outside the first accommodating groove 3231. A rotating shaft 324 is provided between one end of the top block 322 located in the second accommodating groove 3232 and the fourth fixed block 323, and the top block 322 can rotate around the rotating shaft 324; a torsion spring 325 is provided on the outer periphery of the rotating shaft 324, one end of the torsion spring 325 abuts against the top block 322, and the other end of the torsion spring 325 abuts against the bottom of the fourth fixed block 323. In addition, the top block 322 has a first state and a second state. When the top block 322 is in the first state, the length direction of the top surface of the top block 322 is perpendicular to the length direction of the second flow channel 21 (the top surface of the top block 322 remains horizontal), and the top surface of the top block 322 is flush with the top surface of the second accommodating groove 3232. There is a gap between the bottom surface of the top block 322 and the bottom surface of the first accommodating groove 3231 to ensure that when the top block 322 is converted from the first state to the second state, one end of the top block 322 has a rotation space in the second accommodating groove 3232; and, when the top block 322 is in the first state, the orthographic projection of the top block 322 on the horizontal plane partially coincides with the orthographic projection of the second packaging tray 33 on the horizontal plane. At this time, a second packaging tray 33 that has just been filled by the shift mechanism 2 is located below the top block 322. When the top block 322 is converted from the first state to the second state, the top block 322 rotates upward around the rotating shaft 324. When the top block 322 is in the second state, the top surface of the top block 322 is in an inclined state. The arrangement of the top block 322 and related components enables the second packaging tray 33 to be lifted upward by the lifting driver 326, and the side of the second packaging tray 33 will drive the top block 322 to flip upward until the top block 322 flips to separate from the side of the second packaging tray 33 (the top block 322 is in the second state). At this time, the second packaging tray 33 on the second flow channel 21 has been placed in the second storage bin 31. The top block 322 will flip downward to the first state due to the loss of external support, ensuring that it can continue to cooperate with the second packaging tray 33 on the next second flow channel 21. Such an arrangement makes the operation of stacking the second packaging tray 33 into the second storage bin 31 simple and fast, without the need for manual stacking, and does not affect the packaging operation of the packaging tray, which is conducive to improving work efficiency.
