Description

Technical Field

[0001] This disclosure pertains to the technical field of palletizing equipment, specifically relating to an automatic feeding and palletizing device for packaged rice. Background Technology

[0002] Packaged rice is the most common form of staple food purchase in our daily lives. Proper selection, purchase, and storage ensure you enjoy fresh, delicious rice. Currently, packaged rice is generally produced using automated quantitative packaging machines. These machines utilize high-precision weighing sensors and intelligent control systems to quickly and accurately measure the weight of the rice, ensuring that each bag has a consistent weight. The packaged rice bags are then conveyed to the palletizing area, where robotic palletizing systems or fully automated palletizers (as detailed in the previous discussion) automatically and neatly stack the rice bags onto pallets, facilitating subsequent warehousing and transportation.

[0003] In existing technologies, to maximize stability and space utilization, stacking follows specific patterns. The most common stacking pattern for bagged rice is the crisscross stacking, also known as the "seam-seaming" pattern. Odd-numbered layers: all bags are laid flat facing one direction (e.g., the length direction); even-numbered layers: all bags are rotated 90 degrees (facing the width direction) and laid flat, with each bag overlapping the seam of the two layers below. This method, like building a brick wall, interlocks between layers, providing excellent stability and making it the most common stacking pattern for bagged goods.

[0004] Because non-vacuum-packed rice has loose grains inside, the edges cannot be made flat when stacked. This makes the rice easy to slip when it reaches the edge due to the curved surface. Especially when bagged rice is stacked, it is usually stacked 10-20 layers. This makes it very easy for the rice bags to collapse after shifting layer by layer at the edge, affecting the stacking efficiency of rice. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to provide an automatic feeding and palletizing device for packaged rice, which can provide support for the stacked bagged rice, prevent the bagged rice from collapsing after being stacked too high, thereby making the bagged rice more stable during stacking and effectively improving the stacking efficiency of bagged rice.

[0006] To address the above problems, this invention provides an automatic feeding and palletizing device for packaged rice, comprising:

[0007] The workbench has a circular trough on its top for storing bagged rice, a material inlet connected to the circular trough on the right side of the workbench, and a track groove on the inner wall of the circular trough away from the material inlet.

[0008] The conveyor belt, which is installed on the left side of the workbench, is used to transport bagged rice to the top of the workbench.

[0009] A gripping component, positioned on top of the workbench, is used to stack bags of rice;

[0010] The palletizing assembly is set in a circular groove to assist in the palletizing of bagged rice. The palletizing assembly includes a truncated cone that is rotatably connected in the circular groove. A square groove is opened on the top of the truncated cone. A material picking groove and a receiving groove communicating with the square groove are respectively opened on the outer wall of the truncated cone at the four sides of the square groove. There are three receiving grooves.

[0011] A support platform, which is slidably connected in a square groove, is used to connect trays for stacking bagged rice;

[0012] There are two support components, which are respectively installed in two adjacent receiving slots to provide support for the support platform.

[0013] A positioning element, which is located in another receiving groove, is used to connect to the track groove.

[0014] Furthermore, the track trough mainly consists of a turning section, a discharge section, and a reset section. There are two sets of turning sections, one set extending downwards at a counterclockwise 90-degree angle and the other set extending downwards at a clockwise 90-degree angle. The two sets of turning sections are staggered from top to bottom, and the ends of adjacent turning sections are smoothly connected so that the turning sections extend back and forth in an S-shape from top to bottom in the circular groove. The bottom of the turning section is connected to a discharge section that is twice the path length of a single turning section. The discharge section is connected to the top of the turning section near its end through a reset section.

[0015] Furthermore, the positioning component includes a slider, a guide block, and a ball bearing. The slider is fixedly connected to the side wall of the support platform. A groove is provided on the side of the slider away from the support platform. The guide block is connected to the groove by a compression spring. A ball bearing that contacts the track groove is connected to the side of the guide block near the track groove. A slot for accommodating the ball bearing is provided at the end of the single-section turning segment.

[0016] Furthermore, the support component includes a sleeve, an intermediate sleeve, a support rod, a second slider, and a support spring. The sleeve is fixedly connected to the bottom of the receiving groove. The intermediate sleeve is slidably connected inside the sleeve. The support rod is slidably connected inside the intermediate sleeve. The top of the support rod is fixedly connected to the support platform via the second slider. The bottom of the support platform is fixedly connected to the bottom of the receiving groove by a support spring.

[0017] Furthermore, the bottom of the sleeve is provided with an exhaust hole, and a baffle is hinged inside the sleeve near the exhaust hole. A circular hole with a diameter smaller than that of the exhaust hole is provided in the middle of the baffle.

[0018] Furthermore, the support platform has a notch on the side near the material chute, making the support platform C-shaped. The outer wall of the tray has a clearance groove for accommodating the support platform, and the width of the clearance groove is greater than the width of the support platform.

[0019] Furthermore, the bottom of the clearance groove is rotatably connected to a roller that contacts the support platform, and the bottom of the pallet is provided with a slot for inserting forks.

[0020] Furthermore, the gripping assembly includes an X-axis linear actuator, a Y-axis linear actuator, and grippers. The X-axis linear actuator is fixedly connected to the worktable via a support frame. The bottom of the X-axis linear actuator is connected to the Y-axis linear actuator via a slide table. The bottom of the Y-axis linear actuator is connected to grippers for handling bagged rice via a slide table.

[0021] In summary, the present invention has at least one of the following beneficial technical effects:

[0022] 1. This automatic feeding and palletizing equipment for packaged rice can support the bagged rice by placing a pallet in a square groove, thereby preventing the edges of the bagged rice from collapsing. The positioning component cooperates with the track groove, so that the pallet can automatically sink after a layer of bagged rice is laid, and automatically change direction when sinking, so that the bagged rice laid later is staggered with the bagged rice in the current layer, which can effectively improve the palletizing efficiency of bagged rice.

[0023] 2. This automatic feeding and palletizing equipment for packaged rice can provide support to the pallet using support springs through the set support components, so that the bagged rice on the pallet will automatically sink when stacked, which can avoid the bagged rice from interfering with the movement space of the gripper after too much bagged rice is stacked, thereby further improving the palletizing efficiency of bagged rice.

[0040] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0041] See also Figure 1 - Figure 10As shown in the figure, according to an embodiment of the present invention, an automatic feeding and palletizing device for packaged rice is provided, comprising: a workbench 1, the top of which is provided with a circular groove 5 for storing bagged rice, a feeding port 6 communicating with the circular groove 5 on the right side of the workbench 1, and a track groove 7 on the inner wall of the circular groove 5 away from the feeding port 6; a conveyor belt 2, which is mounted on the left side of the workbench 1 for conveying bagged rice to the top of the workbench 1; a gripping assembly 3, which is disposed on the top of the workbench 1 for gripping and stacking bagged rice; and a palletizing assembly 4, which is disposed in the circular groove 5 for assisting in the palletizing of bagged rice. The palletizing assembly 4 includes a frustum 41 rotatably connected in a circular groove 5, a square groove 8 on the top of the frustum 41, and material picking grooves 9 and receiving grooves 10 connected to the square groove 8 respectively on the outer wall of the frustum 41 around the square groove 8, wherein there are three receiving grooves 10; a support platform 42 slidably connected in the square groove 8 for connecting and stacking pallets 11 of bagged rice; two support members 43, which are respectively set in two adjacent receiving grooves 10 for providing support for the support platform 42; and a positioning member 44 set in another receiving groove 10 for cooperating with the track groove 7.

[0042] In this embodiment, observation Figure 1 It can be observed that a workbench 1 is provided, and a conveyor belt 2 is mounted on the left side of the workbench 1, which can be used to transport bagged rice to the top of the workbench 1. Meanwhile, Figure 1 Furthermore, a gripping assembly 3 is found on the top of the workbench 1. The gripping assembly 3 includes an X-axis linear actuator 31, a Y-axis linear actuator 32, and a gripper 33. The X-axis linear actuator 31 is fixedly connected to the workbench 1 via a support frame. The bottom of the X-axis linear actuator 31 is connected to the Y-axis linear actuator 32 via a slide table. The bottom of the Y-axis linear actuator 32 is connected to the gripper 33 for handling bagged rice via a slide table. The X-axis linear actuator 31 and the Y-axis linear actuator 32 can be used to drive the gripper 33 to move along the horizontal axis, thereby handling and stacking the bagged rice transported by the conveyor belt 2.

[0043] Because non-vacuum-packed rice has loose grains, the edges cannot be made flat when stacked. This makes it easy for the rice to slip off the edges due to the curved surface. Especially when bagged rice is stacked, which is usually 10-20 layers high, the rice bags can easily collapse as they shift at the edges, affecting the stacking efficiency.

[0044] Therefore in Figure 2 It can also be seen that the top of the workbench 1 has a circular groove 5, and a palletizing assembly 4 for assisting palletizing is installed in the circular groove 5. At this time, combined with... Figure 2 and Figure 4As can be seen, the palletizing assembly 4 includes a frustum 41 and a support platform 42. The frustum 41 is rotatably connected in the circular groove 5. A square groove 8 is opened on the top of the frustum 41, and the support platform 42 is slidably connected in the square groove 8. A tray 11 for holding bagged rice is placed on the support platform 42. A material picking groove 9 communicating with the square groove 8 is opened on the side wall of the frustum 41.

[0045] When palletizing is required, the bagged rice is simply moved onto the pallet 11 by the X-axis linear actuator 31 and the Y-axis linear actuator 32 using the gripper 33. Since the bagged rice is placed within the square groove 8, it is less likely to fall off due to the support of the side walls of the groove 8. Therefore, the stacked bagged rice can be stably stacked, effectively improving palletizing efficiency. Finally, after the rice is stacked, a forklift can be used to insert its forks into the square groove 8 through the picking port 6 and picking slot 9 to lift the pallet 11, thus removing the stacked bagged rice in one go.

[0046] However, since bagged rice has many stacking layers, the square groove 8 needs to have sufficient depth to improve the stacking effect. As the depth increases, the downward stroke required for the gripper 33 to place the bagged rice will naturally increase, thus affecting the stacking efficiency.

[0047] Therefore, observation Figure 2 - Figure 4 It can be observed that the outer wall of the frustum 41 has receiving grooves 10 on the other three sides corresponding to the square groove 8. Subsequently, two adjacent receiving grooves 10 are connected to support members 43 that can provide support for the support platform 42. At this time, the tray 11 will be positioned above the square groove 8 under the support of the support members 43. After the gripper 33 spreads a layer of bagged rice on the tray 11, the support members 43 will continuously contract under the pressure of the weight of the bagged rice, thereby causing the tray 11 to move down as the bagged rice is placed. This avoids interference with the movement space of the gripper 33 as the number of bagged rice stacking layers increases, and greatly improves the stacking efficiency while ensuring the normal movement of the gripper 33.

[0048] Finally, to improve stability when stacking bagged rice, a staggered stacking method, also known as "seam pressing," is used. Odd-numbered layers: all bags are laid flat facing one direction (e.g., the length direction); even-numbered layers: all bags are rotated 90 degrees (facing the width direction) and laid flat, with each bag pressing against the seam of the two layers below. This method, like building a brick wall, interlocks between layers, providing excellent stability and is the most common stacking method for bagged goods. However, this requires the gripper 33 to adjust the placement of the rice according to the number of layers when stacking, necessitating the addition of a vision system to assist in stacking, which increases the operating cost and complexity of the stacking equipment.

[0049] Therefore, observe Figure 6 and Figure 7It can be observed that a track groove 7 is provided on the inner wall of the circular groove 5 on the side away from the material inlet 6. The track groove 7 mainly consists of a deflection section 71, a discharge section 72, and a reset section 73. There are two sets of deflection sections 71. One set of deflection sections 71 extends downward in a counterclockwise direction of 90 degrees, and the other set of deflection sections 71 extends downward in a clockwise direction of 90 degrees. The two sets of deflection sections 71 are staggered from top to bottom, and the ends of adjacent deflection sections 71 are smoothly connected, so that the deflection sections 71 extend back and forth in an S-shape from top to bottom within the circular groove 5. The bottom of the deflection section 71 is connected to the discharge section 72, which is twice the path length of a single deflection section 71. The discharge section 72 is connected to the top of the deflection section 71 near its end through the reset section 73.

[0050] Subsequently combined Figure 4 and Figure 8 A positioning element 44 can be seen in the last receiving slot 10. The positioning element 44 includes a slider 441, a guide block 442, and a ball bearing 443. The slider 441 is fixedly connected to the side wall of the support platform 42. A groove 12 is provided on the side of the slider 441 away from the support platform 42. The guide block 442 is connected to the groove 12 by a compression spring 13. The ball bearing 443 that contacts the track groove 7 is connected to the side of the guide block 442 near the track groove 7.

[0051] When bagged rice is placed on the tray 11, the tray 11 is driven by gravity to move the support platform 42 downward, so that the ball bearing 443 rolls in the turning section 71, which can be used to drive the truncated cone 41 to rotate, thereby achieving the effect of adjusting the placement direction of the bagged rice.

[0052] However, since the laying of bagged rice is a continuous process, the movement of ball bearing 443 within the turning section 71 is also a continuous process. This causes the truncated cone 41 to rotate slowly. At this time, the orientation of the bagged rice placed on the tray 11 will continue to deflect, which seriously affects the stacking of bagged rice.

[0053] Therefore in Figure 7 As can be seen, the end of the single-segment turning section 71 has a slot 14 for accommodating the ball bearing 443. When the ball bearing 443 moves to the end of one of the turning sections 71, the compression spring 13 pushes the guide block 442 out, causing the ball bearing 443 to engage in the slot 14. Supported by the ball bearing 443 and the inner wall of the slot 14, the tray 11 needs sufficient pressure to continue moving downwards, pressing the guide block 442 back into the groove 12, allowing the ball bearing 443 to re-enter the track groove 7. During the time the ball bearing 443 re-enters the track groove 7, the angle of the tray 11 remains unchanged, ensuring that the bagged rice is placed in a consistent orientation, thus effectively improving the palletizing effect.

[0054] Subsequently, once the current layer is filled with bagged rice, the increased weight of the pallet 11 is sufficient to press the ball bearings 443 into the track groove 7. The ball bearings 443, now in the track groove 7, will then move to the next slot position within the turning section 71, causing the pallet 11 to rotate 90 degrees as it descends. At this point, the bagged rice placed on the next layer will change direction, making the continuous stacking of bagged rice more efficient and stable.

[0055] Finally, when the ball bearing 443 disengages from the bottommost slot 14, it enters the discharge section 72, which has a path length twice that of the turning section 71. At this point, the truncated cone 41... Figure 5 When the device rotates as shown, the feeding chute 9 aligns with the feeding port 6, allowing a forklift to remove the pallet 11 and the stacked bagged rice. After the bagged rice is removed, a new pallet 11 is installed, and then the pallet 11 is reversed, causing the ball bearing 443 to move within the discharge section 72. At this time, there is no bagged rice pressing on the pallet 11, so under the support of the support spring 435, when the ball bearing 443 moves to the reset section 73, the support spring 435 pushes the ball bearing 443 into the reset section 73. Then, the ball bearing 443 moves upward along the reset section 73 to reset, facilitating the start of the next bagged rice stacking.

[0056] Since the production specifications of bagged rice are fixed, with standard bagged rice typically weighing 10kg, 25kg, or even 50kg, the increase in pressure on pallet 11 with each additional layer can be calculated based on the number of bagged rice stacked in a layer. Therefore, the compression spring 13 needs to be selected based on the actual stacking weight of the rice. This avoids insufficient support from the compression spring 13 affecting stacking, while also preventing excessive support from the compression spring 13 from causing pallet 11 to fail to automatically sink and turn after a layer of bagged rice is filled.

[0057] The aforementioned X-axis linear actuator 31 and Y-axis linear actuator 32 are both linearly movable drive methods, such as the motor driving the lead screw to rotate and the slide moving, or the air supply system supplying air to the cylinder to move the slide. These are relatively mature existing technical solutions and do not need to be described in detail.

[0058] In a further preferred embodiment of the present invention, as the number of layers of bagged rice stacked increases, its weight also continuously increases. Therefore, when the weight of the bagged rice is sufficient to press the ball bearing 443 into the track groove 7, subsequent weight will also cause the ball bearing 443 to be pressed back into the track groove 7 as soon as it enters the next slot 14, causing the tray 11 to sink continuously within the square groove 8, affecting placement efficiency. Therefore, observation Figure 4It can be seen that the support member 43 includes a sleeve 431, an intermediate sleeve 432, a support rod 433, a second slider 434, and a support spring 435. The sleeve 431 is fixedly connected to the bottom of the receiving groove 10. The intermediate sleeve 432 is slidably connected inside the sleeve 431. The support rod 433 is slidably connected inside the intermediate sleeve 432. The top of the support rod 433 is fixedly connected to the support platform 42 through the second slider 434. The support spring 435 is fixedly connected between the bottom of the support platform 42 and the bottom of the receiving groove 10.

[0059] When the pallet 11 moves downward, the support spring 435 is compressed and deformed, thus providing greater support force to the slider 434 and increasing the pressure resistance of the pallet 11. Therefore, when the support force of the ball bearing 443 after it is in contact with the slot 14 plus the support force of the support spring 435 is greater than the pressure of the bagged rice, the ball bearing 443 will stop when it moves to the next slot 14 position, which can prevent the pallet 11 from sinking continuously and affecting the palletizing efficiency.

[0060] The compression of the spring is directly proportional to the pressure it receives; therefore, the supporting force provided by the support spring 435 to the pallet 11 when compressed to a certain length is constant. Thus, the support spring 435 can be selected based on the total weight of a layer of bagged rice. Assuming the height change of one section of the turning segment 71 is X, the supporting force provided by the support spring 435 after compressing by X length to the pallet 11 should be close to the weight of a layer of bagged rice. When the first layer of bagged rice is filled, the ball bearing 443 is pressed into the track groove 7. At this point, the ball bearing 443 rolling within the track groove 7 cannot provide effective support. Therefore, the added weight of this layer of bagged rice will compress and deform the support spring 435 until it is compressed by X length, providing sufficient support to the pallet 11 to support the current weight of the bagged rice. At this point, the ball bearing 443 enters the next slot 14. This process can be repeated to stably and efficiently stack bagged rice continuously.

[0061] In a further preferred embodiment of the present invention, since the tray 11 is in motion when it moves downwards, the tray 11 still has downward inertia when the ball bearing 443 is engaged in the slot 14. This causes the inertial force to press the ball bearing 443 back into the track groove 7, and then it rebounds after being supported by the support spring 435, affecting the stability of the placement. Therefore, observation Figure 9It can be observed that a vent hole 15 is provided at the bottom of the sleeve 431. When the pallet 11 moves down, the slider 434 also moves down synchronously, thereby causing the support rod 433 and the intermediate sleeve 432 to move down, reducing the space inside the sleeve 431, thus allowing air to be discharged through the vent hole 15. By reducing the air discharge path, the air discharge efficiency is reduced, and the slider 434 is subjected to air damping when it moves down, which slows down the sinking speed of the pallet 11, thereby reducing its inertial force, allowing the ball bearing 443 to directly stop the pallet 11 when it enters the slot 14, improving the stacking stability.

[0062] Finally, Figure 9 It can also be seen that a baffle 16 is hinged inside the sleeve 431 near the exhaust port 15. A circular hole 17 with a diameter smaller than that of the exhaust port 15 is opened in the middle of the baffle 16. When the tray 11 moves down, the air is discharged through the smaller circular hole 17, which provides a greater damping force to the slider 434 and the tray 11, thus making the downward movement of the tray 11 more stable.

[0063] When the rice is stacked and replaced with a new tray 11, the support spring 435 pushes the slider 434 to reset, which will allow air to enter the sleeve 431. This air will lift the baffle 16, thereby improving the efficiency of air entry and increasing the reset efficiency of the tray 11.

[0064] In a further preferred embodiment of the invention, such as Figure 10 As shown, a notch 18 is machined on the side of the support platform 42 near the material picking groove 9, making the support platform 42 C-shaped. The outer wall of the pallet 11 is provided with a clearance groove 19 for accommodating the support platform 42. The width of the clearance groove 19 is greater than the width of the support platform 42, which allows the pallet 11 to be quickly installed on the support platform 42, thereby improving the efficiency of pallet replacement, reducing equipment downtime, and improving palletizing efficiency.

[0065] In a further preferred embodiment of the invention, because a large number of bags of rice are stacked on the pallet 11, the top wall of the clearance groove 19 of the pallet 11 will fit tightly against the support platform 42 under the pressure of the bags of rice, thereby greatly increasing the friction between the pallet 11 and the support platform 42. Therefore, when the forklift needs to remove the pallet 11, it needs to first lift the pallet 11 to separate it from the support platform 42. However, since the pallet 11 is in the square groove 8, the extent to which the pallet 11 is lifted can only be judged by experience, which greatly tests the operator's skills and affects unloading. Therefore, observation Figure 10It can be observed that the bottom of the clearance groove 19 is rotatably connected to a roller 20 that contacts the support platform 42, and the bottom of the pallet 11 has a slot 21 for inserting forks. When the forks are inserted into the slot 21, the operator only needs to lift the pallet 11. Even if the bottom of the clearance groove 19 abuts against the bottom of the support platform 42 when lifting, the pallet 11 can still be easily removed under the rolling action of the roller 20, reducing the difficulty of unloading and improving the unloading efficiency.

[0066] The implementation principle of the above embodiment is as follows: the bagged rice is transported to the top of the workbench 1 by the conveyor belt 2, and then the X-axis linear driver 31 and the Y-axis linear driver 32 drive the gripper 33 to move the bagged rice onto the tray 11.

[0067] Once a layer of bagged rice is laid out, the compression spring 13 can no longer provide sufficient support for the tray 11, causing the ball bearing 443 to disengage from the slot 14 and enter the steering section 71. At this time, the tray 11 rotates synchronously as it moves down, causing the bagged rice in that layer to collectively change direction. Therefore, the bagged rice laid in the next layer will interlock with the bagged rice in the previous layer, making the bagged rice interlock like brick walls, greatly improving the stacking stability.

[0068] Finally, after the bagged rice is stacked, the ball bearing 443 enters the discharge section 72, so that the feeding trough 9 and the feeding port 6 are aligned. At this time, the stacked bagged rice can be easily removed by a forklift.

[0069] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
