Description

Technical Field

[0001] This utility model relates to the field of pallet processing technology, and in particular to a finished pallet unloading mechanism. Background Technology

[0002] A pallet is a horizontal platform device used for containerizing and stacking goods. It is usually made of plastic. During the manufacturing process, plastic material is poured into an extruder, which melts the material and shapes it into a pallet. After the pallet is manufactured, the injection mold is opened, and a robotic arm places a receiving hopper under the pallet. The robotic arm can move the receiving hopper freely within a certain space. Then, the pallet is extruded from the mold by the extrusion rod. The extruded pallet falls into the receiving hopper. The robotic arm is restarted, and it moves the receiving hopper and the pallet inside it to the braking position. The robotic arm is rotated to turn the opening of the receiving hopper downwards, and the pallet is poured out of the receiving hopper to the designated location, thus realizing the unloading of the pallet.

[0003] After the pallet is injection molded, it falls directly into the receiving hopper. However, since the material of the receiving hopper is relatively hard and the newly formed pallet is relatively soft, when the pallet falls from the mold into the receiving hopper, the contact point between the pallet and the receiving hopper will deform under the influence of gravitational potential energy, which will affect the quality of the pallet. There is a need for further optimization of the pallet's cushioning during unloading. Therefore, this application provides a finished pallet unloading mechanism to meet the needs. Summary of the Invention

[0004] This utility model provides a finished pallet unloading mechanism to solve the problem that the contact point between the pallet and the receiving hopper will deform under the influence of gravitational potential energy when the pallet falls, thus affecting the quality of the pallet.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A finished product pallet unloading mechanism includes a robotic arm and a receiving hopper. The robotic arm controls the receiving hopper to receive and unload materials. The receiving hopper includes an inclined section one, which is fixed to the movable end of the robotic arm. An inclined section two is fixed to the bottom of the inclined section one. Side baffles are fixed to both ends of the inclined section one and the inclined section two. The mechanism also includes:

[0007] A buffer mechanism is provided, comprising a buffer belt, an air inlet on the side of an inclined section away from the buffer belt, a cavity 1 formed between the buffer belt, the inclined section 1, and the side baffle, a cavity 2 formed between the buffer belt, the inclined section 2, and the side baffle, a connecting block fixed at the bend of the buffer belt, the bottom of the connecting block fixed to the bend of the inclined section 1 and the inclined section 2, and a vent hole on the surface of the connecting block for connecting cavity 1 and cavity 2, the air inlet being connected to cavity 1.

[0008] Preferably, the top of the inclined part two is fixed with a vertical part, which is used to prevent the material from falling out of the receiving hopper during the receiving process.

[0009] Preferably, the buffer band includes a first protrusion and a second protrusion. The top of the first protrusion is fixedly connected to the top of the first inclined portion. Both sides of the first protrusion are fixedly connected to the side baffles. The second protrusion is integrally formed at the bottom of the first protrusion. One end of the second protrusion away from the first protrusion is fixed to the top of the second inclined portion. Both sides of the second protrusion are fixedly connected to the side baffles. Circular holes are provided on the surfaces of both the first and second protrusions. The circular holes on the surface of the first protrusion communicate with the first cavity, and the circular holes on the surface of the second protrusion communicate with the second cavity.

[0010] Preferably, the thickness of the second protrusion is greater than the thickness of the first protrusion.

[0011] Preferably, the connection between the first protrusion and the second protrusion is arc-shaped, with the arc opening facing upwards.

[0012] Preferably, the top of the connecting block has a concave surface, which is fixed to the bottom of the connection between the first protrusion and the second protrusion.

[0013] Preferably, the top width of the connecting block is greater than the bottom width.

[0014] Preferably, the top of the inclined part one is integrally formed with an inclined downward connecting part, a connecting plate is fixed between the connecting part and the inclined part one, a flange mounting seat is fixed on the side of the connecting part away from the inclined part one, and the flange mounting seat is fixedly connected to the output end of the robotic arm.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, a buffer strip is set up. The buffer strip is made of rubber and has a certain degree of flexibility. There is a gap between the buffer strip and the inner wall of the receiving hopper. When the pallet falls onto the buffer strip, the gravitational potential energy of the pallet during the fall will be absorbed by the stretching and deformation of the buffer strip, avoiding local deformation of the pallet due to impact, thus protecting the pallet. Secondly, the thickness of the second protrusion of the buffer strip is greater than the thickness of the first protrusion. When the pallet falls, the bottom of the pallet contacts the second protrusion. The thickened second protrusion makes the position of the second protrusion more wear-resistant, improving the overall durability.

[0017] By setting up air inlets and connecting blocks, the connecting blocks fix the bent parts of the buffer strip. Air is injected into cavities one and two through the air inlets, causing protrusions one and two to bulge upwards. The bulging protrusions one and two can make contact with the falling pallet earlier, reducing the gravitational potential energy generated by the pallet's fall, thereby further protecting the pallet and preventing local deformation. Secondly, the upward-bulging parts have a higher cushioning effect, further improving the pallet's protective ability.

[0018] By setting circular holes, the air introduced into cavity one and cavity two will be ejected from the circular holes. Since the air output from the circular holes is less than the air intake from the air inlets, protrusion one and protrusion two can protrude upward normally. The air ejected through the circular holes can cushion the falling pallet. By cushioning the pallet with gas, local deformation of the bottom of the pallet is further avoided. Secondly, the blown air can also cool the pallet, allowing it to cool and solidify quickly, thereby fundamentally preventing local deformation of the pallet and achieving protection for the pallet.

Detailed Implementation

[0026] The following is a detailed description of a finished product pallet unloading mechanism provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; for some known technologies, those skilled in the art can also use other alternative methods to implement the invention. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figures 1-5 As shown, an embodiment of this utility model provides a finished product pallet unloading mechanism, including a robotic arm 1 and a receiving hopper 2. The robotic arm 1 is used to control the receiving hopper 2 to receive and unload materials. The receiving hopper 2 includes an inclined portion 3, which is fixed to the movable end of the robotic arm 1. An inclined portion 4 is fixed to the bottom of the inclined portion 3. Side baffles 6 are fixed to both ends of the inclined portion 3 and the inclined portion 4. The mechanism also includes:

[0028] The buffer mechanism 7 includes a buffer strip 9. An air inlet 8 is provided on the side of the inclined section 3 away from the buffer strip 9. A cavity 12 is formed between the buffer strip 9, the inclined section 3, and the side baffle 6. A cavity 23 is formed between the buffer strip 9, the inclined section 4, and the side baffle 6. A connecting block 14 is fixed to the bend of the buffer strip 9. The bottom of the connecting block 14 is fixed to the bend of the inclined section 3 and the inclined section 4. A vent 16 is provided on the surface of the connecting block 14 to connect the cavity 12 and the cavity 23. The air inlet 8 is connected to the cavity 12. The buffer belt 9 can absorb the impact force of the pallet falling by its own deformation, so as to avoid the pallet from being deformed by the impact and achieve protection. The air inlet 8 inflates the cavity 12. The gas enters the cavity 2 13 through the vent 16, causing the buffer belt 9 to bulge and make contact with the pallet in advance, thus enhancing the buffering effect. The connecting block 14 fixes the bend of the buffer belt 9 to prevent the buffer belt 9 from forming a downward arc shape. At the same time, the vent 16 ensures the air pressure balance between the two cavities. The side baffle 6 prevents the pallet from falling from both sides of the receiving hopper 2.

[0029] like Figures 1-4 As shown in this embodiment, a vertical part 5 is fixed to the top of the inclined part 2 4. The vertical part 5 is used to prevent the material from falling from the receiving hopper 2 during the receiving process. When the pallet falls into the receiving hopper 2, the vertical part 5 can block the pallet from moving to the outside of the inclined part 2 4, so as to prevent the pallet from falling from the front end of the receiving hopper 2 due to excessive impact force, thus ensuring the stability of the receiving process and reducing the risk of the pallet falling and being damaged.

[0030] like Figures 1-5As shown, in this embodiment, the buffer strip 9 includes a first protrusion 10 and a second protrusion 11. The top of the first protrusion 10 is fixedly connected to the top of the first inclined portion 3. Both sides of the first protrusion 10 are fixedly connected to the side baffles 6. The second protrusion 11 is integrally formed on the bottom of the first protrusion 10. The end of the second protrusion 11 away from the first protrusion 10 is fixed to the top of the second inclined portion 4. Both sides of the second protrusion 11 are fixedly connected to the side baffles 6. Circular holes 17 are provided on the surfaces of both the first protrusion 10 and the second protrusion 11. The circular hole 17 on the surface is connected to the cavity 12, and the circular hole 17 on the surface of the second protrusion 11 is connected to the cavity 13. The first protrusion 10 and the second protrusion 11 form a double-layer buffer structure through bulging. When the tray falls, it first contacts the first protrusion 10 and then contacts the second protrusion 11, absorbing the impact force in stages and improving the protection effect. The circular hole 17 can discharge some of the gas in the cavity. When the gas is ejected, it forms a reverse buffer force on the tray, while avoiding the cavity air pressure from being too high and causing the buffer strip 9 to break. The fixed connection method ensures the overall structural stability of the buffer strip 9.

[0031] like Figure 3 and Figure 4 As shown in this embodiment, the thickness of the second protrusion 11 is greater than that of the first protrusion 10. The second protrusion 11 is thicker, has stronger wear resistance and deformation resistance, and can withstand greater impact force after the pallet falls, thus extending the service life of the buffer strip 9. At the same time, the thicker structure can provide more stable support, preventing the pallet from tilting due to excessive deformation of the buffer strip 9 during the slide, and ensuring smooth material discharge.

[0032] like Figure 3 and Figure 4 As shown in this embodiment, the connection between protrusion 10 and protrusion 11 is arc-shaped with the arc opening facing upward. The arc connection can disperse the pressure of the pallet passing through the bend, avoiding damage to the connection of the buffer strip 9 due to stress concentration. At the same time, the arc surface can guide the pallet to transition smoothly, reduce the friction and collision between the pallet and the buffer strip 9, and prevent damage to the pallet edge.

[0033] like Figure 5 As shown in this embodiment, the top of the connecting block 14 is provided with a concave surface 15. The concave surface 15 is fixed at the bottom of the connection between the first protrusion 10 and the second protrusion 11. The concave surface 15 is adapted to the arc of the bend of the buffer band 9, which can fit tightly and support the connection, enhance the structural strength of the bend of the buffer band 9, prevent it from being overstretched and deformed under the impact of the pallet, and ensure the stable buffering performance of the buffer band 9.

[0034] like Figure 5 As shown in this embodiment, the top width of the connecting block 14 is greater than the bottom width. The wider top can increase the contact area with the buffer strip 9 and improve the support stability.

[0035] like Figures 2-4 As shown in this embodiment, the top of the inclined part 3 is integrally formed with an inclined downward connecting part. A connecting plate is fixed between the connecting part and the inclined part 3. A flange mounting seat is fixed on the side of the connecting part away from the inclined part 3. The flange mounting seat is fixedly connected to the output end of the robotic arm 1. The flange mounting seat realizes a stable connection between the receiving hopper 2 and the robotic arm 1, ensuring that the robotic arm 1 can accurately control the position and posture of the receiving hopper 2. The connecting plate enhances the connection strength between the connecting part and the inclined part 3, preventing the receiving hopper 2 from shaking or breaking due to impact force during material receiving, and improving the overall structural stability.

[0036] Working principle: The robotic arm 1 starts and adjusts the position of the receiving hopper 2 to prepare it for receiving materials. At the same time, air is injected into cavity 12 through the air inlet 8. The air flows into cavity 13 through the vent 16 of the connecting block 14. Since the air output of the round hole 17 is less than the air intake of the air inlet 8, the air pressure in cavity 12 and cavity 13 gradually increases, pushing the protrusions 10 and 11 of the buffer belt 9 to bulge upward. The bulged protrusions 10 and 11 can contact the falling tray earlier, preparing for receiving the material.

[0037] When the finished product pallet falls into the receiving hopper 2, it first contacts the raised part 10 of the upward-protruding buffer strip 9. The buffer strip 9 is made of rubber and is flexible. The impact of the pallet will cause the raised part 10 to stretch and deform, absorbing part of the gravitational potential energy. Then the pallet continues to fall and contacts the second raised part 11. The second raised part 11 is thicker than the first raised part 10. It can not only further absorb energy through deformation, but also be more wear-resistant due to its greater thickness. During this process, the air in the first cavity 12 and the second cavity 13 is ejected from the round hole 17. The gas forms a buffer force on the pallet, further reducing the impact force. At the same time, the ejected air cools the pallet and helps it cool and solidify quickly. When receiving materials, the vertical part 5 can effectively block the pallet and prevent it from falling from the receiving hopper 2.

[0038] The robotic arm 1 drives the receiving hopper 2 to the unloading position, and then adjusts the posture of the receiving hopper 2 to complete the unloading action. Under its own weight and the tilt angle of the receiving hopper 2, the pallet slides down along the first tilt part 3 and the second tilt part 4. During the slide, the pallet is in continuous contact with the buffer belt 9. The buffer belt 9 can still play a certain buffering role to prevent the pallet from being damaged by friction and collision during the slide.

[0039] After the material is unloaded, robotic arm 1 resets the receiving hopper 2 to the receiving state, waiting for the next receiving command.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
