Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and particularly relates to an automatic pallet-unloading and feeding machine for yellow peach processing. Background Art

[0002] A yellow peach pallet-unloading and feeding machine is a device specifically used to unload yellow peach cans from a pallet and feed them. The use of a yellow peach pallet-unloading and feeding machine can improve production efficiency and reduce manual operation, and is suitable for the automation requirements of canned food manufacturers or canned bottle filling production lines.

[0003] The utility model with the publication number CN221521311U discloses an automatic pallet-unloading and feeding machine for wine bottles. By starting the first motor, the driving bevel gear rotates. Under the meshing drive of the driving bevel gear, the driven bevel gear drives the bidirectional screw rod to rotate, so that the two concave frames slide in the threaded groove of the hollow cylinder, and drive the corresponding chute frames to move in opposite directions. The two push plates slide and contract on the outer wall of the connecting plate until the opposite ends of the baffle are attached to and clamped on both sides of the wine bottle pallet. As the concave frame moves, the distance between the baffles changes, so as to adjust the clamping range of the baffle, and thus improve the applicable range of the device.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-9 As shown, the present invention is an automatic pallet unloading and feeding machine for yellow peach processing, including a base 1. A connecting plate 7 is movably connected to the surface of the base 1. A bracket 15 is fixedly installed on the surface of the connecting plate 7. A steel beam 24 is arranged inside the bracket 15. An outer suspension frame 30 is arranged outside the steel beam 24; On the outer side of the steel beam 24, there is a belt 27. On the outer surface of the belt 27, protective shells 28 are fixedly connected at equal intervals. Inside the protective shell 28, a first driver 281 is fixedly installed.

On both side surfaces of the outer hanging frame 30 near the upper end, there are symmetrically arranged movable grooves 32. On both side surfaces of the outer hanging frame 30 near the lower end, there are fixedly connected clamping rods 33. Inside the outer hanging frame 30, there is a movable inner hanging frame 34.

On both side surfaces of the inner hanging frame 34 near the upper end, there are fixedly connected support ear rods 36. On the side surface of the inner hanging frame 34 near the lower end, there is a fixedly connected first linkage shaft 37. On the surface of the first linkage shaft 37, there are symmetrically sleeved and connected short connecting arms 38. Near one end edge of the surface of the short connecting arm 38, there is a rotatably connected long connecting arm 39. On the surface of the long connecting arm 39, there is a fixedly connected connecting frame 40. On the surfaces of the short connecting arm 38 and the long connecting arm 39, there is a rotatably connected second linkage shaft 42; On the top surface of the base 1, a hanging frame 2 is welded and fixed. Inside the base 1, first motors 6 are symmetrically and fixedly installed. The output end of the first motor 6 is fixedly connected to a first lead screw 3. Inside the base 1, on both sides of the first lead screw 3, there are fixedly connected sliding rods 4. On the surfaces of the first lead screw 3 and the sliding rods 4, there is a sleeved and connected connecting seat 5. The connecting seat 5 is fixedly connected to the connecting plate 7. During the process of palletizing and loading yellow peach cans, first, an external transmission device is installed at the inner bottom position of the base 1. When the yellow peach cans are connected to the relevant clamping accessories, at this time, it is necessary to control it to lift a certain height to adapt to the external device for loading. The user can operate the two first motors 6 arranged in alignment to operate. After the output end drives the first lead screw 3 to rotate, cooperating with the symmetrically installed sliding rods 4, the connecting seats 5 at both ends will stably move up synchronously until they reach the specified height. Then, by operating the first motor 6 in reverse again, the connecting seat 5 can be controlled to stay at the initial position again, waiting for the next round of loading process; On the surface of the connecting plate 7 near the middle part, a docking plate 8 is welded and fixed. On the surface of the docking plate 8 near the lower end, there are symmetrically arranged lower limit grooves 9. On the surface of the docking plate 8 near the upper end, there are symmetrically arranged upper limit grooves 10. On one end surface of the docking plate 8 at the middle part, a double-acting cylinder is fixedly installed. The output end of the double-acting cylinder is fixedly connected to a linkage plate 11. On the surface of the connecting plate 7 near the upper end, there is a positioning plate. On the surface of the positioning plate, there is a rotatably connected swing arm 14. On the surface of the connecting plate 7 near the lower end, there is a fixedly connected mounting joint 12. On the surface of the mounting joint 12, there is a rotatably connected first cylinder 13. The output end of the first cylinder 13 is rotatably connected to the swing arm 14; The bracket 15 is fixedly welded to the swing arm 14. A guiding groove 16 is provided on the surface of the bracket 15 near one end. A second cylinder 17 is fixedly installed on the top surface of the bracket 15 near the guiding groove 16. A connecting frame 18 is fixedly installed inside the bracket 15. Anti-disconnection members 19 are symmetrically and fixedly installed on the top surface of the connecting frame 18. The anti-disconnection members 19 are embedded and connected with the guiding groove 16. A second motor 20 is fixedly installed on the bottom surface of the connecting frame 18; A bracket 21 is rotatably connected inside the connecting frame 18. The output end of the second motor 20 is fixedly connected to the bracket 21. A guide rail 22 is fixedly connected to the side surface of the bracket 21. A transverse movement mechanism 23 is movably connected to the surface of the guide rail 22. For the process of loading together with the stacker, at this time, only need the bracket 21 to normally stop inside the bracket 15, so that the supporting blocks 232 on the side surface of the bracket 21 are arranged in alignment. Then, according to the size of the stacker, control the operation of the double-axis cylinder. After its output end extends an appropriate length, the linkage plate 11 will cooperate with the lower limit groove 9 and the upper limit groove 10, so that the installation section 12 and the positioning plate stay in a certain position. Then, the first cylinder 13 can be driven. Under the drag of its output end, finally the swing arm 14 will rotate around the positioning plate. The bracket 15 welded to the lower end of the swing arm 14 will move in a certain arc and slowly approach the stacker until the supporting block 232 is inserted into the supporting groove on the surface of the stacker. Then, it can drive the matching base 1 accessory to lift the entire stacker for loading. When the stack needs to be separated, for the yellow peach canned food with hard bottles, such as glass jar yellow peach canned food, the user can control the operation of the second cylinder 17. Under the limiting and matching action of the anti-disconnection member 19 and the guiding groove 16, the connecting frame 18 will stay in a suitable position. Then, the operation of the second motor 20 can be controlled to make the entire bracket 21 rotate 90 degrees around the axis. Because the two brackets 15 are welded and fixed to the swing arm 14 in a staggered manner, after both groups of brackets 21 are rotated, they will cooperate with the bracket 15 body to surround the glass jar yellow peach canned food to be loaded from all around. Similarly, through the operation of the double-axis cylinder, the gap between the brackets 15 can be slowly controlled in the horizontal direction, and then the distance can be finely adjusted in cooperation with the second cylinder 17, so that the bracket 21 is further closely attached to the surface of the outer glass jar yellow peach canned food in the vertical direction. The clamping friction can be further increased by cooperating with the belt 27. Finally, the bulk glass jar yellow peach canned food can be clamped as a whole, and then the subsequent lifting and loading steps can be carried out; Connecting frames 25 are symmetrically and fixedly connected to the two short side surfaces of the steel beam 24. A transmission wheel 26 is rotatably connected inside the connecting frame 25. A second driver is fixedly installed on the bottom surface of one of the connecting frames 25. The output end of the second driver is fixedly connected to the transmission wheel 26. The transmission wheel 26 is sleeved and connected with the belt 27; A through hole 31 is provided in the middle of the surface of the outer suspension frame 30. A rubber sleeve 41 is sleeved and connected to the surface of the connecting frame 40. When it is necessary to separate stacked materials, for example, for canned yellow peaches with relatively soft bottle bodies, such as canned yellow peaches in iron cans, after the user manipulates the two sets of brackets 21 to flip, the belt 27 will be exposed at this time. The user can control the operation of the second driver. After its drive pulley 26 rotates, the belt 27 will eventually be driven to rotate until multiple protective shells 28 on its surface are arranged on one side of the drive pulley 26. Then, in cooperation with the operation of the first motor 6, the entire clamping fitting will gradually move from top to bottom. During this process, the user can synchronously control the first driver 281 in the protective shell 28 to operate. Then, the second lead screw 29 will rotate in cooperation with the thread groove 35. Under the combined action of the support ear rod 36 and the first linkage shaft 37, the entire inner suspension frame 34 will vertically move downward along the movable groove 32. Due to the restriction of the movement of the long connecting arm 39 by the locking lever 33, finally, under the action of the second linkage shaft 42, the short connecting arm 38 and the long connecting arm 39 will rotate around the locking lever 33. Then, the connecting frame 40 on the surface of the long connecting arm 39 will gradually adhere to the surface of the canned yellow peaches in the iron can, and then the clamping positioning can be completed. The provided rubber sleeve 41 can further enhance the protection of the canned yellow peaches in the iron can; The transverse movement mechanism 23 includes a steel frame 231. Support blocks 232 are symmetrically welded and fixed to the side surface of the steel frame 231. Support bodies 233 are welded and fixed to the two end surfaces of the steel frame 231. A vehicle frame 234 is welded and fixed to the surface of the support body 233. Side guide wheels 235 are symmetrically rotatably connected to the top surface of the vehicle frame 234 near the side edge. A traveling wheel 236 is rotatably connected to the middle of the top surface of the vehicle frame 234. A reduction motor 237 is fixedly installed on the surface of one of the vehicle frames 234. The output end of the reduction motor 237 is fixedly connected to the traveling wheel 236. The side guide wheels 235 are sleeved and connected to the guide rail 22. Whether it is the unstacking and loading operation of hard glass tank bodies or soft glass tank bodies, when it is necessary to finely adjust the positions of the support blocks 232 or the connecting frames 40, the user needs to control the reduction motor 237 to operate. After its output end drives the traveling wheel 236 to rotate, the traveling wheel 236 abutting against the surface of the guide rail 22 will reactively drive the entire steel frame 231 to move transversely.

[0020] Working principle of the present invention: During the process of unloading and loading canned yellow peaches, first install the external transmission device at the inner bottom position of the base 1. After the canned yellow peaches are connected to the relevant clamping accessories, it is necessary to control it to lift a certain height to adapt to the external device for loading. The user can operate the two first motors 6 set for alignment to operate. After driving the first lead screw 3 to rotate at the output end, and cooperating with the symmetrically installed slide rods 4, the connecting seats 5 at both ends will move up stably and synchronously until they reach the specified height. Then, reverse the first motor 6 again, and the connecting seats 5 can be controlled to stay at the initial position again, waiting for the next round of loading process. For the process of loading together with the pallet, at this time, only need to make the bracket 21 dock normally inside the bracket 15, so that the supporting blocks 232 on the side surface of the bracket 21 are arranged in alignment. Then, according to the size of the pallet, control the operation of the double-axis cylinder. After the output end extends an appropriate length, the linkage plate 11 will cooperate with the lower limit groove 9 and the upper limit groove 10, so that the mounting section 12 and the positioning plate stay at a certain position. Then, the first cylinder 13 can be driven. Under the dragging of its output end, finally the swing arm 14 will rotate around the positioning plate, and the bracket 15 welded to the lower end of the swing arm 14 will move slowly towards the pallet in a certain arc until the supporting block 232 is inserted into the supporting groove on the surface of the pallet. Then, it can drive the accessories cooperating with the base 1 to lift the entire pallet for loading. When the pallet needs to be separated, for canned yellow peaches with a relatively hard bottle body, such as canned yellow peaches in glass jars, the user can control the operation of the second cylinder 17. Under the limiting and cooperating action of the anti-disconnection 19 and the guiding groove 16, the connecting frame 18 will stay at a suitable position. Then, the second motor 20 can be controlled to operate, so that the entire bracket 21 rotates 90 degrees around the axis. Because the two brackets 15 are welded and fixed to the swing arm 14 in a staggered manner, after the two brackets 21 have rotated, they will cooperate with the bracket 15 body to surround the canned yellow peaches in glass jars to be loaded from all around. Similarly, through the operation of the double-axis cylinder, the gap between the brackets 15 can be slowly controlled in the horizontal direction, and then the distance can be finely adjusted in cooperation with the second cylinder 17, so that the bracket 21 is further closely attached to the surface of the outer canned yellow peaches in glass jars in the vertical direction. Cooperating with the belt 27 can further increase the clamping friction force. Finally, the loose canned yellow peaches in glass jars can be clamped as a whole, and then the subsequent lifting and loading steps can be carried out. When the pallet needs to be separated, for canned yellow peaches with a relatively soft bottle body, such as canned yellow peaches in iron cans, after the user operates the two brackets 21 to flip, the belt 27 will be exposed at this time. The user can control the operation of the second driver. After driving the transmission wheel 26 to rotate, finally the belt 27 will be driven to rotate until all the protective shells 28 on its surface are arranged on one side of the transmission wheel 26. Then, cooperating with the operation of the first motor 6, the entire clamping accessory moves gradually from top to bottom. During this process, the user can synchronously control the operation of the first driver 281 in the protective shell 28. Then, the second lead screw 29 will cooperate with the thread groove 35 to rotate.Under the combined action of the lug rod 36 and the first linkage shaft 37, the entire inner suspension frame 34 will move vertically downward along the movable groove 32. Due to the restriction of the movement of the long connecting arm 39 by the locking rod 33, finally, under the action of the second linkage shaft 42, the short connecting arm 38 and the long connecting arm 39 will rotate around the locking rod 33. Then, the connecting bracket 40 on the surface of the long connecting arm 39 will gradually attach to the surface of the canned yellow peaches in an iron can, and then the clamping and positioning can be completed. Moreover, the provided rubber sleeve 41 can further enhance the protection of the canned yellow peaches in the iron can.
