Description

Technical Field

[0001] This invention relates to the field of nut processing equipment technology, and in particular to a nut stacking device. Background Technology

[0002] In the mass production of nuts, scattered stacking of nuts not only hinders subsequent transfer, transportation, counting, and processing operations, but also affects production efficiency. Conventional methods typically use vibratory feeders to arrange the nuts, feeding them sequentially along a conveyor track, and then receiving them from the end of the track using insert rods and connectors to achieve stacking. However, because the nuts must be fed one by one along the track before stacking, the stacking speed is slow, resulting in low efficiency. Furthermore, conveying nuts via vibration is prone to missing nuts, making it difficult to meet the requirements for batch stacking and arrangement. Summary of the Invention

[0003] To address the aforementioned technical problems, the purpose of this invention is to provide a nut stacking device that can arrange and stack nuts quickly and efficiently, effectively meeting the needs of batch nut stacking and sorting.

[0004] The technical solution of the present invention is implemented as follows: a nut stacking device, comprising a box with a storage cavity, a disturbance mechanism, and an interlocking stacking mechanism; The storage cavity has an arc-shaped bottom surface; the arc-shaped bottom surface has a central axis extending front and rear; The disturbance mechanism is located inside the storage cavity and is used to drive the nut inside the storage cavity to move back and forth between the low and high points on the arc-shaped bottom surface. The box body is provided with several sets of guide grooves arranged at intervals on the left and right sides; the guide grooves extend back and forth, and their width is adapted to the thickness of the nut; the guide grooves include a falling section formed on the arc-shaped bottom surface and a receiving section extending from one end of the falling section to the outside of the storage cavity; the falling section has an inclined bottom surface that allows the nut to move toward the receiving section. The receiving section has a nut resting position; the side wall of the receiving section has a through hole with an open top corresponding to the nut resting position; the through holes on each group of receiving sections form a left-right extending interlocking channel; The interlocking stacking mechanism includes a rod arranged corresponding to the interlocking channel and a drive assembly for driving the rod to move between a first position and a second position in the left-right direction; the rod is detachably connected to the drive assembly; in the first position, the rod is located at one end of the interlocking channel; in the second position, the rod is interlocked within the interlocking channel.

[0005] Furthermore, the disturbance mechanism includes a rotating shaft and a disturbance plate; the rotating shaft is disposed on the box body and rotates around the central axis extending front and rear; the first end of the disturbance plate is connected to the rotating shaft, and the second end forms a clearance fit with the arc-shaped bottom surface.

[0006] Furthermore, the disturbance plate includes a rigid body and a rubber plate; the first end of the rigid body is connected to the rotation shaft, and the second end is provided with the rubber plate.

[0007] Furthermore, a limiting baffle is provided on the downstream side of the nut's resting position within the receiving section.

[0008] Furthermore, the drive end of the drive assembly is provided with a plug-in base; the plug-in base is provided with a slot with an open top; the tail end of the plug rod is provided with a plug plate; the plug plate and the slot are inserted and engaged vertically.

[0009] Furthermore, the drive assembly includes a first drive device for driving the plug body to rotate about a central axis extending forward and backward between a falling position and a raised position, and a second drive device for driving the first drive device to move between a first position and a second position. In the falling position, the insertion rod corresponds to the insertion channel on the left and right; in the lifting position, the insertion rod moves upward away from the insertion channel.

[0010] Furthermore, the first driving device includes a base, a rotating rod disposed on the base and rotating about a central axis extending back and forth, and a first driver for driving the rotating rod to rotate; the plug-in seat is disposed on the rotating rod.

[0011] Furthermore, the feed troughs are arranged opposite each other on the box body.

[0012] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: 1. This invention utilizes a combination of a disturbance mechanism and a guide trough. The disturbance mechanism drives the nuts in the storage chamber to move back and forth between the low and high points of the arc-shaped bottom surface, allowing the nuts to slide into the guide trough and be guided to the outside of the storage chamber. The cooperation of several sets of guide troughs enables the synchronous conveying and arrangement of multiple sets of nuts. Through the use of an interlocking stacking mechanism, driven by the drive assembly, the insert rod can sequentially penetrate through the interlocking channel into the interior of the nuts at their resting positions on each receiving section. By disassembling and lifting the insert rod, each set of nuts can be moved out of the guide trough and stacked sequentially onto the insert rod.

[0013] 2. With the cooperation of the plug-in base, the plug plate on the plug rod is assembled to the plug-in base by plugging, so as to realize the quick disassembly and replacement of the plug rod, which is conducive to the quick stacking of nuts and has strong practicality.

[0014] 3. With the cooperation of the drive components, when the insertion rod is inserted into the interior of each group of nuts, the first drive device in the drive components can drive the insertion seat and the insertion rod to move from the falling position to the lifting position, thereby synchronously and automatically lifting each group of nuts and removing them from the guide groove. It has a high degree of automation, saves time and effort, effectively meets the needs of batch stacking and sorting of nuts, and has strong practicality. Attached Figure Description

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0017] like Figure 1-11 The diagram illustrates a nut stacking device according to this embodiment. This device enables the stacking of nuts, such as round or hexagonal nuts, as described in the prior art. The stacking device includes a housing 1, a disturbance mechanism 2, and an interlocking stacking mechanism 3. The housing 1 contains a storage cavity 11 for storing nuts. The top of the storage cavity 11 is open. The storage cavity 11 has a downwardly recessed arc-shaped bottom surface 12. This arc-shaped bottom surface 12 is defined by a central axis extending forward and backward.

[0018] The aforementioned disturbance mechanism 2 is installed inside the storage cavity 11 to drive the nut inside the storage cavity 11 to move back and forth between the low and high points on the arc-shaped bottom surface 12. In its specific structural design, the disturbance mechanism 2 includes a rotating shaft 21, a disturbance plate 22, and a rotating actuator 23. The rotating shaft 21 extends front to back and is mounted on the housing 1 via bearings, allowing it to rotate about its central axis. The aforementioned disturbance plate 22 has a width extending front to back; its first end in the longitudinal direction is fixedly connected to the rotating shaft 21, and its second end in the longitudinal direction forms a clearance fit with the arc-shaped bottom surface 12. The distance between the second end of the disturbance plate 22 and the arc-shaped bottom surface 12 is less than the thickness of a nut. When the rotating shaft 21 rotates, the disturbance plate 22 moves accordingly, thereby pushing the nut inside the storage cavity 11 to move back and forth between the low and high points on the arc-shaped bottom surface 12. The aforementioned disturbance plate 22 includes a rigid body 221 and a rubber plate 222. The rigid body 221 is made of metal and has a plate-like structure. The first end of the rigid body 221 is connected to the rotating shaft 21, and the second end is fixedly fitted with a rubber plate 222. The rubber plate 222 has a designed elastic deformation capability. When the rubber plate 222 pushes the nut to move and encounters significant resistance, the rubber plate 222 can undergo elastic deformation to prevent the disturbance plate 22 from getting stuck.

[0019] The aforementioned rotary driver 23 is mounted on the housing 1 and is connected to the rotary shaft 21 in a transmission manner so as to drive the rotary shaft 21 to rotate.

[0020] In this embodiment, several sets of guide grooves 13 are machined at intervals on the left and right sides of the box body 1. The number of guide grooves 13 is determined according to the actual design. In this embodiment, there are 10 sets of guide grooves 13, with 5 sets of guide grooves 13 arranged on each side of the left and right symmetrical central axis of the arc-shaped bottom surface 12. The aforementioned guide grooves 13 extend front and back, and their width is adapted to the thickness of the nut so that the nut can enter the guide groove 13 in a preset posture. It should be noted that the width or outer diameter of the nut in this embodiment is greater than the thickness of the nut. The guide groove 13 includes a falling section 14 formed on the arc-shaped bottom surface 12 and a receiving section 15 extending from one end of the falling section 14 to the outside of the storage cavity 11. The falling section 14 has an inclined bottom surface 141 that allows the nut to move towards the receiving section 15. This inclined bottom surface 141 has a designed angle relative to the horizontal plane, allowing the nut entering the falling section 14 to slide on the inclined bottom surface 141 and be guided towards the receiving section 15 via the inclined bottom surface 141. This structural design allows the nut in the storage cavity 11 to be guided to the outside of the storage cavity 11 in a preset posture via the guide groove 13. The bottom surface of the receiving section 15 is a horizontal plane.

[0021] The aforementioned receiving section 15 has a nut resting position. The nut is guided to the receiving section 15 via an inclined bottom surface 141 and can rest at this nut resting position. A through hole 151 with an open top is machined on the side wall of the receiving section 15 corresponding to the nut resting position. When the nut rests at the nut resting position, the inner hole of the nut corresponds left and right to the through hole 151. A left-right extending insertion channel 7 is formed between the through holes 151 on each set of receiving sections 15. The aforementioned insertion stacking mechanism 3 includes a rod 6 and a drive assembly. The rod 6 has a designed outer diameter and length to be able to pass through the inner hole of the nut. The rod 6 is arranged corresponding to the insertion channel 7, and the drive assembly is connected to the rod 6 to drive the rod 6 to move between a first position and a second position in the left-right direction. In this embodiment, the rod 6 is detachably connected to the drive assembly to facilitate the disassembly and replacement of the rod 6. Under the drive assembly, when the rod 6 is in the first position, the rod 6 is located at one end of the insertion channel 7. Initially, the insert rod 6 extends in the left-right direction, with its first end corresponding to one end of the insertion channel 7. When the insert rod 6 is in the second position, it enters the insertion channel 7 from one end and is inserted into the channel 7. When the nut is in the nut resting position, the insert rod 6 can simultaneously be inserted into the inner hole of the nut. By removing the insert rod 6 from the drive assembly and lifting it upwards, the insert rod 6 is moved out of the insertion channel 7 from the top opening of the through hole 151, thereby transferring the nut in the receiving section 15 onto the insert rod 6. When the insert rod 6 is tilted, the nuts move closer together, allowing them to stack on the insert rod 6.

[0022] In this embodiment, a limiting wall 152 is machined on the downstream side of the nut stopping position within the receiving section 15. When the nut is guided into the receiving section 15, it is blocked by the limiting wall 152, thereby stopping at the nut stopping position. The drive assembly includes a connector 43 mounted on its drive end. The connector 43 has a slot 431 with an open top. A plate is fixedly mounted on the tail end of the insertion rod 6. The plate engages with the slot 431, allowing the insertion rod 6 to be detachably mounted on the connector 43. Specifically, the drive assembly includes a first drive device 4 and a second drive device 5. The connector 43 is mounted on the drive end of the first drive device 4, which drives the connector 43 to rotate between a lowered and raised position around its central axis. The first drive device 4 is mounted on the drive end of the second drive device 5, which drives the first drive device 4 to move between a first and a second position. When the connector 43 is in the lowered position, the insertion rod 6 is in its initial left-right extended state, corresponding to the insertion channel 7. When the connector body 43 is in the raised position, the insertion rod 6 moves upward away from the insertion channel 7. Through this structural design, when the insertion rod 6 is driven to the aforementioned second position, the connector body 43 is then driven to move from the lowered position to the raised position, thereby automatically raising the insertion rod 6 to automatically remove the nut from the receiving section 15. The aforementioned second drive device 5 is a linear drive mechanism in the prior art, preferably an electric push rod or a cylinder. The drive end of the second drive device 5 is connected to the base 41 to drive the base 41 to move between the first and second positions, thereby driving the entire first drive device 4 to move between the first and second positions.

[0023] In the specific structural design, the aforementioned first driving device 4 includes a base 41, a rotating rod 42, and a first driver 44. The rotating rod 42 extends forward and backward, and is mounted on the base 41 via bearings, allowing it to rotate around its central axis. The first driver 44 is mounted on the base 41 and is connected to the rotating rod 42 via a gear mechanism to drive its rotation. The aforementioned insertion seat 43 is fixedly mounted on the rotating rod 42, allowing it to move with the rotating rod 42. The insertion seat 43 is disposed on the rotating rod 42. The aforementioned guide grooves 13 are arranged opposite each other on the housing 1, allowing the nuts in the storage cavity 11 to be guided to the front and rear sides of the storage cavity 11. Insert rods 6 and insertion seats 43 are arranged corresponding to the front and rear guide grooves 13 to improve the stacking efficiency of the nuts.

[0024] In practical use, a certain number of nuts are placed into the storage cavity 11, driving the rotating shaft 21 to rotate. The rotating shaft 21 drives the agitator 22 to move back and forth within the storage cavity 11, causing the nuts in the storage cavity 11 to move back and forth between the low and high points on the arc-shaped bottom surface 12. During the agitation process, the nuts enter each feeding section in a preset posture and slide down onto the receiving section 15 via the inclined bottom surface 141, thereby guiding the nuts to the outside of the storage cavity 11 in a preset posture. Due to the obstruction of the limiting baffle 152, the nuts stop at the nut stopping position on the feeding section. The postures of the nuts at the nut stopping position are consistent, thereby realizing the synchronous conveying and arrangement of multiple sets of nuts. The insertion rod 6 is inserted into the insertion seat 43. The first driving device 4 drives the insertion seat 43 from the raised position to the lowered position, so that the insertion rod 6 forms an initial state of left and right extension, with the first end of the insertion rod 6 corresponding left and right to one end of the insertion channel 7. The second driving device 5 drives the first driving device 4 to move, causing the insertion rod 6 to move from the first position to the second position, so that the insertion rod 6 is sequentially inserted into the inner hole of each nut located at the nut stopping position. Then, the first driving device 4 drives the insertion seat 43 to move from the falling position to the lifting position, so as to lift the insertion rod 6 upward, thereby removing each nut from the guide groove and stacking it on the insertion rod 6. Then, the insertion rod 6 is driven to move back to the first position and detached from the insertion seat 43 to remove the stacked nuts. Through the combination of the above methods, nuts can be arranged, sorted and stacked, and the stacking speed is fast and the work efficiency is high. The insertion plate on the insertion rod 6 is assembled to the insertion seat 43 by insertion, so as to realize the quick disassembly and replacement of the insertion rod 6, which is conducive to the rapid stacking of nuts. The degree of automation is high, saving time and labor, effectively meeting the needs of batch stacking and sorting of nuts, and has strong practicality.
