Description

Technical Field

[0001] The invention belongs to the technical field of industrial automated production equipment, and particularly relates to a turning device for irregular materials. Background Art

[0002] When workpieces have planar structures around their perimeter, such as the cuts of betel nut slices, hemispheres, half olives, and half cylinders, irregular semi-finished products require adjustment before entering automated production. Due to the inherent irregularities of these products, the sorting process is not uniform, and the sheer volume of products necessitates a high level of speed. Manual placement is complex, slow, labor-intensive, and involves frequent product contact, which can be detrimental to food hygiene.

[0003] In existing betel nut processing, the vibrating flipping and sorting device used first places the slices onto a semi-finished product tray. This requires manual labor or specialized equipment, resulting in low efficiency and high costs. This process relies on applying a certain frequency of vibration to the tray to flip and sort the slices, but it also suffers from high energy consumption, loud noise, high vibration, low efficiency, limited flipping success rate, and the need for further flipping after slicing. Subsequent processing still requires manual labor or other equipment, making it unsuitable for industrial production.

[0004] Prior art has proposed improved structures for betel nut turning devices during betel nut processing, but these still suffer from slow processing speeds and low success rates. Chinese Patent Publication No. CN214494727U discloses a turning device for processing betel nuts. A feed conveyor belt transfers the betel nuts to a betel nut chamber at the top of a turning rod. The turning rod and a guide conveyor belt cooperate to turn the nuts within the chamber and drop them onto a discharge conveyor belt, thereby achieving mechanized, automatic turning of the betel nuts. While this achieves a certain degree of turning of the betel nuts for processing, enabling automated production, the use of a turning rod and a guide conveyor belt results in slow processing speeds, a low success rate, and the potential for direct damage to the betel nuts, impacting the yield of the finished product. Furthermore, the device fails to automatically sort the betel nuts, resulting in low overall efficiency.

[0005] Therefore, how to provide an efficient and accurate flipping device is a technical problem that needs to be solved urgently in this field. Summary of the Invention

[0024] 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] It should be noted that if there are directional indications involved in the embodiments of the present invention, such as up, down, left, right, front, back..., then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. Additionally, if there are descriptions such as "first, second", "S1, S2", "step one, step two", etc. involved in the embodiments of the present invention, then such descriptions are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features or indicating the execution order of the method, etc. Those skilled in the art can understand that all those that do not violate the inventive concept of the invention should be included in the protection scope of the present invention.

[0026] As Figure 1 shown, a turning device for irregular materials is shown according to some exemplary embodiments. Taking the turning of an irregular material with a plane as an example for illustration, but not limited thereto, the turning device of the present invention can also be optionally used for turning materials with irregular surfaces such as the slicing of betel nuts and olives. As Figure 1 shown, the turning device 40 is detachably fixed on the workbench 10 and is inclined with respect to the workbench 10 along the direction of workpiece travel, for turning the workpiece during the betel nut processing while realizing the directional conveyance of the workpiece.

[0027] Specifically, as Figure 2 and Figure 3 shown, the turning device 40 includes at least two support seats 41, at least one support frame 42, at least one turning cylinder member 44, and at least one turning roller member 45. Among them, the support seats 41 are arranged at intervals from each other. After the turning cylinder member 44 passes through the support seats 41, it is rotatably arranged relative to the support seats 41 and is inclined with respect to the workbench 10 along the direction of workpiece travel; the support frame 42 is arranged between the support seats 41, and the turning roller member 45 is rotatably fixed on the support frame 42, is arranged at an interval from the turning cylinder member 44, and extends parallel to the axis direction of the turning cylinder member 44; preferably, the turning cylinder member 44 and the turning roller member 45 are arranged to rotate in the same direction; specifically, along the direction of workpiece travel, the input end side of the turning cylinder member 44 is higher than the output end side of the turning cylinder member 44 in the vertical direction, so that while the workpiece is turned by the turning cylinder member, it continuously and orderly advances along the direction of workpiece travel.

[0028] In this embodiment, a flipping device of the present invention is provided. On the one hand, through the flipping cylinder member and the flipping roller member with the same rotation direction, the workpiece located between the gaps of the two can be automatically overturned under the combined action of the flipping cylinder member and the flipping roller member and sorted into an orderly arrangement; through two groups of flipping cylinder members and flipping roller members with different rotation directions, the workpiece can be flipped along both groups, improving the flipping accuracy and efficiency. On the other hand, since the input end side of the flipping cylinder member is higher than the output end side of the flipping cylinder member in the vertical direction, while the workpiece is being flipped by the flipping cylinder member, it can be continuously and orderly pushed forward along the direction of the workpiece's travel, having the remarkable characteristics of simple structure, high efficiency, low energy consumption, high speed, high success rate, light weight, and flexible layout.

[0029] Preferably, the radius of the flipping cylinder member 44 is much larger than the radius of the flipping roller member 45, and / or, with respect to the same workpiece 100 to be processed, the friction coefficient of the outer peripheral surface material of the flipping roller member 45 is larger than the friction coefficient of the outer peripheral surface material of the flipping cylinder member 44; specifically, in order to improve the efficiency of flipping the workpiece, the friction coefficient of the outer peripheral surface material of the flipping roller member 45 takes a relatively large value. In other words, the friction coefficient of the outer peripheral surface material of the flipping cylinder member 44 is k, and the friction coefficient of the outer peripheral surface material of the flipping roller member 45 is K. At this time, K > k and the value of k is small. Thus, through the significant difference in the contact area between the flipping cylinder member and the flipping roller member and the workpiece, and / or the difference in the friction coefficient of the selected materials, the acting forces on different surfaces of the workpiece are different. Considering the shape characteristics of the workpiece with a planar structure on its periphery, such as the cut surface of betel nut slices, hemispheres, semi-olives, semi-cylinders, etc., the automatic flipping of the workpiece is realized and sorted into an orderly arrangement.

[0030] Optionally, as Figure 2As shown, the turning device 40 further includes at least one baffle 43 fixed to the support frame 42. The baffle 43 is obliquely fixed to the top end of the support frame 42, and its length extends parallel to the axis direction of the turning cylinder member 44, and its width extends along the radial direction against the turning roller member 45. Optionally, the axis of the turning roller member 45, the axis of the turning cylinder member 44, and the baffle 43 are arranged in the same plane. Specifically, the baffle 43 includes a first baffle 431 and a second baffle 432 that are respectively arranged at the top end of the turning cylinder member 44 and are symmetrically arranged along the vertical plane passing through the axis of the turning cylinder member 44, and the first baffle 431 and the second baffle 432 are arranged at an angle. Preferably, the support frame 42 is a U-shaped bracket with an open top end. The first baffle 431 and the second baffle 432 are respectively fixed on the inclined surfaces at the top end of the bracket. After passing through the inside of the support frame 42, the turning roller member 45 is rotatably arranged with the support frame 42. Further, the turning roller member 45 is fixed on the baffle 43 and is located on the same side where the support frame 42 is connected to the baffle 43. By providing the baffle 43, it is possible to prevent the workpiece from rolling out of the working area during the turning process between the turning cylinder member 44 and the turning roller member 45. If the workpiece rolls out of the working area, the workpiece that is about to roll out can be returned to the working area to make the turning process continuous and more efficient.

[0031] Preferably, for the convenience of directly acting on the workpiece and improving the turning efficiency, the turning roller member 45 is fixed on the end face of the baffle 43 close to the end side of the turning cylinder member 44 and is arranged at an interval from the turning cylinder member 44. Further, the gap between the turning roller member 45 and the turning cylinder member 44 is smaller than the size of the workpiece. Thus, since the size of the workpiece is larger than the gap, it is ensured that the workpiece remains on the surface of the turning cylinder, constantly turning and jumping, neither falling nor passing through the gap and being omitted, and is always restricted between the turning roller member and the turning cylinder member until it reaches a stable state where it cannot be turned over and travels along the gap between the turning roller member and the turning cylinder.

[0032] Optionally, the turning cylinder member 44 and the turning roller member 45 are paired and symmetrically arranged along the connecting end face. Thus, by the paired and symmetrically arranged turning cylinder member and turning roller member, it is possible to significantly improve the turning or processing of workpieces with directional and / or significantly different shapes, improve the applicability, effectiveness, and reliability of the turning mechanism, and then improve the efficiency of the overall operation.

[0033] Optionally, Figure 3 Another structural schematic diagram of the turning device shown in the embodiment is as Figure 3As shown, the flipping cylinder member 44 includes a flipping cylinder driver 441, a flipping cylinder fixing base 442, and a flipping cylinder 444. Among them, the fixed end of the flipping cylinder driver 441 is detachably fixed to the workbench 10 through the flipping cylinder fixing base 442 and the support base 41. The movable end of the flipping cylinder driver 441 is integrally connected to the flipping cylinder 444 and is arranged to move together. The flipping cylinder 444 is rotatably arranged on the support base 41 and extends along the direction of workpiece travel. Thus, the flipping cylinder can be driven by the flipping cylinder driver to perform a rotary motion, and then the rotary motion of the flipping cylinder member is realized. Preferably, the outer surface of the flipping cylinder 444 is processed with a threaded groove to cooperate with the rotation direction of the flipping cylinder to provide a forward thrust for the workpiece and accelerate the forward speed of the workpiece, thereby enhancing the overall speed of workpiece travel. Further, to ensure that the workpiece travels in the same direction on the outer surface of the flipping cylinder 444, the flipping cylinders 444 are provided in pairs and symmetrically arranged along the connecting end side. Moreover, the thread directions of the threaded grooves processed on the outer peripheral side surfaces of the flipping cylinders 444 are opposite. At the same time, the rotation directions of the two first drivers 441 are opposite. Thus, by setting the thread directions of the threaded grooves processed on the outer peripheral side surfaces of the flipping cylinders to be opposite and setting the rotation directions of the two groups of first drivers to be opposite, it is ensured that the workpiece is pushed in the same direction on the outer surface of the flipping cylinder member.

[0034] In a preferred embodiment of the present invention, as Figure 3 shown, the flipping cylinder driver 441 includes a first flipping cylinder driver 441a and a second flipping cylinder driver 441b. The flipping cylinder fixing base 442 includes a first flipping cylinder fixing base 442a and a second flipping cylinder fixing base 442b. The flipping cylinder 444 includes a first flipping cylinder 444a and a second flipping cylinder 444b. Among them, one end of the first flipping cylinder 444a is rotatably fixed to the workbench 10 through a bracket, and the relatively arranged other end is integrally connected to the movable end of the first flipping cylinder driver 441a and is arranged to move together. One end of the second flipping cylinder 444b is rotatably fixed to the same bracket as the first flipping cylinder 444a and is symmetrically arranged with the first flipping cylinder 444a along the connecting end side. The relatively arranged other end is integrally connected to the movable end of the second flipping cylinder driver 441b and is arranged to move together. The fixed end of the first flipping cylinder driver 441a is detachably fixed to the workbench 10 through the first flipping cylinder fixing base 442a and the support base 41. The fixed end of the second flipping cylinder driver 441b is detachably fixed to the workbench 10 through the second flipping cylinder fixing base 442b and the support base 41. Thus, through the symmetrically arranged first flipping cylinder and second flipping cylinder, and the first flipping cylinder driver and second flipping cylinder driver separately connected thereto, the precise control of the rotation speed and rotation direction of the first flipping cylinder and the second flipping cylinder is extremely convenient, and then it is ensured that the workpiece can travel in the order of the operation.

[0035] Preferably, threaded grooves are machined on the outer peripheral sides of the first flipping cylinder 444a and the second flipping cylinder 444b, and the thread directions are opposite; further, along the direction of workpiece travel, the first flipping cylinder 444a is located at the front end of the second flipping cylinder 444b and is coaxially arranged. In other words, along the vertical direction, the height of the output end of the first flipping cylinder 444a is not lower than the height of the input end of the second flipping cylinder 444b. That is, the first flipping cylinder 444a and the second flipping cylinder 444b are coaxially arranged, and after being symmetrically arranged along the connecting end side surface, a conveying channel is inclined at an angle with the workbench 10. Thus, through the inclined and continuous first flipping cylinder and the second flipping cylinder, in cooperation with the threaded grooves with opposite directions machined on the outer peripheral sides of the first flipping cylinder and the second flipping cylinder, and the opposite rotation directions of the first flipping cylinder and the second flipping cylinder, whether it is in the counterclockwise direction or the clockwise direction, workpieces with large differences in external shape directionality can also be effectively flipped, avoiding the difficulty of flipping and the resulting flipping failure of directional workpieces in the case of one-way flipping, improving the flipping success rate and processing efficiency of various workpieces, and improving the effectiveness and adaptability of processing workpieces with large differences in external shape; under the combined action of the threaded grooves with opposite directions, the workpiece will always be pushed in the same direction, that is, when the workpiece slides on each section of the outer peripheral sides of the first flipping cylinder and the second flipping cylinder, it can be pushed in the direction of workpiece travel.

[0036] For example, as Figure 2 and Figure 3 shown, when the driving member 441a of the first flipping cylinder rotates in the clockwise direction, driving the first flipping cylinder 444a to rotate in the clockwise direction, under the combined action of the threaded groove machined on the outer peripheral side of the first flipping cylinder 444a and the self-gravity of the workpiece, it is pushed to the baffle 431, and under the combined action of the flipping roller member 45, it travels along the direction of A until the output end of the first flipping cylinder 444a; the driving member 441b of the second flipping cylinder rotates in the counterclockwise direction, driving the second flipping cylinder 444b to rotate in the counterclockwise direction, under the combined action of the threaded groove machined on the outer peripheral side of the second flipping cylinder 444b, the thread on the outer peripheral side of the first flipping cylinder 444a, and the self-gravity of the workpiece, it is pushed to the baffle 432, and under the combined action of the flipping roller member 45, it continues to travel along the direction of A.

[0037] Preferably, to avoid interference or obstruction in movement caused by installation and manufacturing errors between the drive shaft and the input shaft during operation of the turning cylinder 444, a turning cylinder coupling 443 is provided between the turning cylinder driver 441 and the turning cylinder 444. One end of the turning cylinder coupling 443 is integrally connected to the movable end of the turning cylinder driver 441 and is arranged to move therewith, while the other end, which is arranged opposite to the movable end, is connected to the turning cylinder 444. Specifically, the turning cylinder coupling 443 includes a first coupling 443a and a second coupling 443b. The first coupling 443a is provided between the first turning cylinder driver 441a and the first turning cylinder 444a and is connected to the movable end of the turning cylinder 444a. The second coupling 443b is provided between the second turning cylinder driver 441b and the second turning cylinder 444b and is connected to the movable end of the turning cylinder 444b.

[0038] In a preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the flip roller component 45 is two groups, including a first flip roller component 45a and a second flip roller component 45b, wherein the first flip roller component 45a is rotatably fixed on the end side surface of the first baffle 431 close to the end of the flip cylinder component 44, and extends along the long side direction of the first baffle 431; the second flip roller component 45b is rotatably fixed on the end side surface of the second baffle 432 close to the end of the flip cylinder component 44, and extends along the long side direction of the second baffle 432. Preferably, the fixed end of the first flip roller component 45a is arranged in the middle position of the first baffle 431, and the movable end of the first flip roller component 45a extends along the long side direction of the first baffle 431 in the direction of the first flip cylinder driving component 441a; the fixed end of the second flip roller component 45b is arranged in the middle position of the second baffle 432, and the movable end of the second flip roller component 45b extends along the long side direction of the second baffle 432 in the direction of the second flip cylinder driving component 441b; further, the first flip roller component 45a and the second flip roller component 45b are extended in opposite directions.

[0039] Specifically, the flip roller assembly 45 includes a second driving member 451, a second fixed seat 452 and a flip roller 453, wherein the fixed end of the second driving member 451 is fixed to the baffle 43 through the second fixed seat 452, and the movable end of the second driving member 451 is connected to the flip roller 453 as a whole and is arranged to move together; the end of the flip roller 453 away from the second fixed seat 452 extends parallel to the axial direction of the flip cylinder assembly 44.

[0040] Optionally, in order to ensure the smoothness of transmission, it also includes a driving wheel 454 connected to the movable end of the second driving member 451, and a driven wheel 455 fixed as a whole with the flip roller 453 and arranged to move together, and the driven wheel 455 is arranged to mesh with the driving wheel 454.

[0041] As Figure 4 and Figure 5 shown, the working principle of the flipping device for irregular materials provided by the present invention is as follows:

[0042] When the first flipping cylinder 444a rotates clockwise under the action of the first flipping cylinder driving member 441a, the workpiece 100 is driven by the first flipping cylinder 444a to approach and press against the first baffle 431 and the flipping roller 453. At this time, the contact point between the workpiece 100 and the first flipping cylinder 444a is point a1. There is a frictional force f with a friction coefficient of k along the arc tangent direction of the outer peripheral side of the workpiece 100, and the direction is to the right. As Figure 4 shown, the contact point between the workpiece 100 and the flipping roller 453 is point b1. There is a frictional force F with a friction coefficient of K along the arc tangent direction of the outer peripheral side of the workpiece 100. When K > k and the value of k is small. At a certain moment, the resultant force of the gravity G of the centroid o of the workpiece 100 and the supporting forces, pressures, frictional forces f and F at the contact points a and b is zero. The frictional forces f and F generate torques in the same direction relative to the centroid o, causing the material to rotate in the direction shown in the figure.

[0043] After the workpiece 100 is flipped, as Figure 5 shown, the workpiece 100 has a plane that fits well with the first flipping cylinder 444a, and there is still a frictional force f, with the direction to the right. The first flipping cylinder 444a still transports the workpiece 100 to the flipping roller 453. The fulcrum of the workpiece 100 on the first flipping cylinder 444a is a2, which has moved to the left and is away from the centroid o at this time; the contact point between the flipping roller 453 and the workpiece 100 is b2, and there is also a frictional force F. At a certain moment, the resultant force of the gravity G, the supporting force at point a2, the pressure at point b2, the frictional force f, and the frictional force F at the centroid o is also zero. However, taking the fulcrum a2 as the research object, the torque generated by the sliding frictional force f is zero, and the torque generated by the frictional force F is in the opposite direction to the torque generated by the gravity G. When the value of k is selected small enough, the pressure at point b2 is small enough, and the torque generated by the pressure relative to the fulcrum a2 is small enough to be ignored. And the frictional force F at point b2 is equal to the product of the pressure and the value of K. When the value of K is small enough, it is not enough to counteract the restoring torque generated by the gravity G relative to the fulcrum a2, and the workpiece 100 maintains the overturned posture in the figure and is relatively stable within the flipping area until it is sent out of the flipping mechanism.

[0044] Based on the same principle, after a part of the workpiece 100 that has not been overturned enters the input end of the second turning cylinder 444b, since the rotation direction of the second turning cylinder 444b is opposite to that of the first turning cylinder 444a, that is, it rotates counterclockwise, the workpiece 100 passing through the surface of the first turning cylinder 444a is pushed towards the second baffle 432, so as to perform a reverse overturning operation on the workpiece 100 that has not been completely overturned, and it can ensure that the workpiece 100 that has been overturned remains in the overturned state, and finally is sorted into an orderly arrangement.

[0045] In summary, for the turning device provided in this application, through the turning cylinder member and the turning roller member with the same or matching rotation directions, the workpiece located between the gaps of the two can be automatically overturned under the combined action of the turning cylinder member and the turning roller member, and sorted into an orderly arrangement; due to the significant difference in the contact area between the turning cylinder member and the turning roller member and the workpiece, the acting forces on different planes of the workpiece are different, and combined with the shape characteristics of the workpiece after rough machining, the automatic overturning of the workpiece is realized; through the paired and symmetrically arranged turning cylinder member and turning roller member, the directional influence caused by the tendency of the workpiece shape can be effectively avoided, and the success rate, efficiency and adaptability of the workpiece turning are improved; by setting the thread directions of the thread grooves machined on the outer peripheral side of the turning cylinder to be opposite, and setting the rotation directions of the first driving member to be opposite, the workpiece is pushed in the same direction on the outer surface of the turning cylinder member.

[0046] In addition, for the control system in this application, the start and stop of the motor can be controlled through this control system. The composition of the control system is well known to those skilled in the art and will not be elaborated here.

[0047] The turning device for irregular materials provided in the above embodiments of this application at least has the following characteristics:
