Description

Technical Field

[0001] This invention belongs to the technical field of lunch box recycling equipment, specifically relating to an automatic recycling and packaging device for press-type fast food boxes and a fast food box recycling method. Background Technology

[0002] The use of fast food containers in China is increasing, and ordering takeout has become a way of life, especially in buildings and residential areas. However, the disposal of used fast food containers has become a new problem. They often quickly take up space in the "other waste" category due to their large size, and the large volume and low density of these containers during transportation leads to low logistics efficiency.

[0003] Fast food containers are mostly made of PP (polypropylene) and PS (polystyrene), or biodegradable plastics, with some made of cardboard or starch. These materials are relatively heat-resistant, highly malleable, and recyclable, and the corresponding recycling technologies are relatively mature. However, a complete industrial chain for recycling and reusing waste paper or mineral water bottles has not yet been formed. The main reason is the high cost and low logistics efficiency in the intermediate links of recycling.

[0004] Existing fast food container recycling equipment can be divided into three categories: The first category focuses on sorting and cleaning, but the equipment is too complex and costly. For example, the fast food container waste timely processing and recycling device with patent number 202010265481.4 focuses on separating and cleaning food, but this is not the main problem. Or rather, even if it is cleaned, it is not suitable to use it directly as swill and still needs to be processed again. The main problem is the logistics issue, namely the insufficient compression of fast food containers and the lack of connection with subsequent logistics links, especially the lack of packaging. The second category attempts to solve the logistics problem through packaging and other methods. Existing technologies are mainly based on compression, with packing straps as the main consumable. The equipment is complex, costly, and consumes a lot of materials and energy, lacking an effective solution. The third category solves the logistics problem through other methods, such as crushing. However, it is usually difficult to compress the crushed fragments into blocks. It also suffers from the problems of complex equipment, high cost, high energy consumption during use, high price and high consumption of consumables such as blades or blade heads, and high noise, making it difficult to popularize and promote.

[0005] In summary, there is currently a lack of a simple, easy-to-operate, and low-cost technology to recycle, sort, compress, package, store, and transport fast food containers in a pollution-free manner, and especially to integrate with the existing waste recycling system to form an effective industrial chain. Summary of the Invention

[0016] The present invention also provides a method for recycling fast food boxes, which uses the above-mentioned automatic recycling and unpacking device for fast food boxes, including the following steps:

[0017] S1. The fast food box is placed into the box from the dispensing port and is located on the lower tray. The first sensor detects the fast food box.

[0018] S2. The first displacement device drives the piercing needle to move upward, the piercing needle passes through the fast food box and upward through the upper pressure plate, and drives the rope to move.

[0019] S3. The second gripper clamps the needle, the first gripper releases the needle, and the third displacement device drives the second displacement device and the upper pressure plate to move above the transfer groove, while the rope is stretched.

[0020] S4. The second displacement device drives the upper pressure plate to move downward and press the fast food box onto the pressure plate, while the rope is stretched.

[0021] S5. After the fast food box is placed on the pressure plate, the second displacement device drives the upper pressure plate to move upward, and the third displacement device drives the second displacement device and the upper pressure plate to move to the initial position.

[0022] S6. The first gripper clamps the piercing needle, the second gripper releases the piercing needle, and the first displacement device moves the piercing needle downward to the initial position to wait for the next fast food box.

[0023] S7. Fast food boxes are continuously stacked to form a fast food box bag;

[0024] S8. When the third sensor on the transfer trough detects that the stack of fast food boxes has reached a predetermined height, the knotting component starts to work. At this time, the threading needle is in the initial position, the rope forms the first parallel segment, the fourth displacement device drives the eagle beak knotting machine to move forward, and the eagle beak knotting machine knots the rope of the first parallel segment for the first time to form the first knot.

[0025] S9. After the first knot is tied, the first displacement device drives the threading needle to move downward, and the end of the rope is separated from the threading needle. After the end of the rope is separated, the first displacement device drives the threading needle to move upward to the initial position, and the threading needle hooks the rope again.

[0026] S10. The actuating component moves the rope near the end of the rope winder to the other end to form a second parallel section. The fifth displacement device drives the eagle beak knotting machine to move to the second parallel section of the rope. The eagle beak knotting machine knots the rope in the second parallel section a second time to form a second knot. The rope with the second knot is connected to the threading needle.

[0027] S11. The sixth displacement device drives the scissors and the third clamp to move forward. The third clamp clamps the rope with the first knot. The scissors cut the rope between the first knot and the second knot. The rope with the first knot and the fast food box form a bundle. The rope with the second knot is straightened by the rope winder.

[0028] S12, the sixth displacement device drives the third gripper to move backward, and the third gripper pulls the bundle down into the second drawer.

[0029] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0030] 1. This invention, by setting up a box-passing component, a box-pressing component, and a transfer channel, can connect and compress multiple fast food boxes in series.

[0059] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0060] like Figure 1 As shown, the automatic recycling and packaging device for press-type fast food boxes of this application includes a box body 1, which is a rectangular box. The front of the box body 1 is provided with a feeding port 11 near the upper part. The fast food box is put into the box body 1 through the feeding port 11. The lower part of the front of the box body 1 is provided with a first drawer 7, which is used to hold the residue that falls out of the fast food box. The lower part of the right side of the box body 1 is provided with a second drawer 8 near the back. The second drawer 8 is pulled out from the right side.

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 7 and Figure 8 As shown, the box body 1 is equipped with a box-feeding assembly 2, a box-pressing assembly 3, a transfer trough 4, a knotting assembly 5, and a shearing and dragging assembly 6. The box-feeding assembly 2 includes a lower support plate 21, a threading needle 22, a rope 23, a rope winder 24, a first displacement device 25, and a first gripper 26. The lower support plate 21 is a rectangular plate, and its position corresponds to the dispensing port 11. When the fast food box is placed into the box body 1 from the dispensing port 11, it is located on the lower support plate 21. The lower support plate 21 has multiple first through holes 212 to facilitate the direct falling of fast food box residue. The food is placed in the first drawer 7 below, which contains an eco-friendly bag. Residue falls into the bag. A first sensor 91 is installed on the lower tray 21. The first sensor 91 uses a distance sensor to detect whether there is a fast food box on the lower tray 21. The needle 22 is a flat, elongated needle with a needle tip at the top and a hook 221 at the bottom, facing outwards. The rope 23 has a rope buckle at its end that hangs on the hook 221, and the remaining part of the rope 23 is wound around a rope winder 24.

[0062] like Figure 1 , Figure 24 and Figure 25 As shown, the rope winder 24 is located in the lower left area of ​​the threading needle 22. The rope winder 24 adopts an existing elastic rope winder and includes a drum 241, a fixed shaft 242, and a torsion spring 243. The rope 23 is wound on the drum 241. The fixed shaft 242 is connected to the drum 241 through a bearing. When the rope 23 is pulled out, it drives the drum 241 to rotate. The torsion spring 243 is connected to the fixed shaft 242 and is located on one side of the drum 241. The straight arm of the torsion spring 243 abuts against the drum 241. The drum 241 is provided with a groove corresponding to the straight arm of the torsion spring 243. When the rope 23 pulls the drum 241 to rotate, the straight arm of the torsion spring 243 always exerts an opposite force on the drum 241 under the elastic force of the torsion spring 243, so that the rope 23 is appropriately tensioned and sufficient rebound distance is ensured. The second sensor 92 uses an existing tension sensor and is connected to the rope winder 24 to sense the overall tension on the rope winder 24. The threading needle 22 continuously pulls the rope 23 outward. When the rope 23 is exhausted, the overall tension on the rope winder 24 will increase significantly. After reaching a predetermined value, a signal that the rope 23 is exhausted will be issued. The side wall of the housing 1 is also provided with an observation window at the position corresponding to the rope winder 24 so that the rope can be manually observed and replaced.

[0063] The first displacement device 25 adopts an existing single-axis slide and is set directly below the lower support plate 21. The first displacement device 25 is connected to the inner wall of the box 1 through a bracket. The first gripper 26 adopts an existing electric gripper and is used to grip the piercing needle 22 from one side of the lower part of the piercing needle 22. The first gripper 26 is set on the first displacement device 25. The first displacement device 25 can drive the piercing needle 22 to move up and down. In the initial position, the first displacement device 25 makes the top of the piercing needle 22 located on the lower end face of the lower support plate 21. The lower support plate 21 is provided with a first slot 211 corresponding to the piercing needle 22. The first slot 211 opens to the right on the lower support plate 21 to facilitate the piercing needle 22 to move to the right. When the piercing needle 22 moves upward, it can pass through the lower support plate 21 and thus penetrate the fast food box.

[0064] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the pressing assembly 3 includes an upper pressing plate 31, a second displacement device 32, a third displacement device 33, and a second gripper 34. The shape and position of the upper pressing plate 31 correspond to the lower support plate 21. The upper pressing plate 31 has a conical protrusion for pressing down on the fast food box, thereby performing a semi-destructive compression on the fast food box. The upper pressing plate 31 is provided with a second through hole 311 corresponding to the piercing needle 22. When the piercing needle 22 moves upward and penetrates the fast food box, it passes through the second through hole 311 and thus penetrates the upper pressing plate 31. Two second displacement devices 32 are provided and existing electric telescopic rods are used. The second displacement devices 32 are connected to the upper pressing plate 31 to drive the upper pressing plate 31 to move up and down. The third displacement device 33 uses an existing single-axis slide. Displacer 32 is connected to third displacementr 33. Third displacementr 33 drives second displacementr 32 to move left and right, thereby driving upper pressure plate 31 to move left and right. Second gripper 34 is connected to third displacementr 33. Second gripper 34 adopts existing electric gripper. The working part of second gripper 34 is located on the upper surface of upper pressure plate 31. When the needle 22 passes through upper pressure plate 31, second gripper 34 can clamp the upper part of needle 22 from the side. When second gripper 34 clamps needle 22, first gripper 26 releases needle 22. When third displacementr 33 drives second gripper 34 to move to the right, it can drive needle 22 to move to the right, thereby driving the fast food box passing through needle 22 to move to the right.

[0065] like Figure 1 , Figure 2 and Figure 13As shown, the transfer trough 4 includes a pressure plate 41 and a side plate 42. The transfer trough 4 is located inside the box 1, to the right of the box assembly 2 and directly above the first drawer 7. The pressure plate 41 is connected to the inner wall of the box 1, and the side plate 42 is also connected to the inner wall of the box 1. The third displacement device 33 moves the fast food box to the right and directly above the transfer trough 4. The second displacement device 32 pushes the upper pressure plate 31 downward to press the fast food box onto the pressure plate 41. Multiple fast food boxes are stacked to form a fast food box package. There is a gap between the side plate 42 and the pressure plate 41. The pressure plate 41 is provided with multiple third through holes to facilitate the dropping of the residue in the fast food box into the first drawer 7 below through the gap and the third through holes. The inner wall of the box 1 is provided with a third sensor 93 at the corresponding position of the transfer trough 4. The third sensor 93 adopts an existing distance sensor to sense whether the fast food boxes in the transfer trough 4 have reached the predetermined stacking height. An arc-shaped shallow groove is provided at the upper end of the side plate 42 corresponding to the position of the rope 23 to prevent the rope 23 from sliding back and forth at the upper end of the side plate 42 when it is dragged by the threading needle 22. The line connecting the groove and the elastic rope winder should intersect with the axis of the threading needle 22, and the groove and the threading needle 22 should be in corresponding positions to facilitate the hook 221 of the threading needle 22 to hook the rope 23 from bottom to top during the movement in step S9.

[0066] like Figure 2 , Figure 7 , Figure 8 , Figure 10 and Figure 21As shown, the knotting assembly 5 includes a beak knotting machine 51, a fourth displacement device 52, a fifth displacement device 53, and a toggle assembly 54. The beak knotting machine 51 adopts an existing strapping machine knotting mechanism, such as the one with authorization announcement number CN. The knotting mechanism disclosed in utility model patent 210364512U has a fourth displacement device 52 connected to the beak knotting machine 51. The fourth displacement device 52 uses an existing cylinder to push the beak knotting machine 51 to move back and forth. The fifth displacement device 53 is located in the box 1 between the box assembly 2 and the transfer groove 4. The fifth displacement device 53 uses an existing single-axis slide table. The fifth displacement device 53 includes a fifth base 531 and a fifth sliding table 532 that slides left and right on the fifth base 531. The fourth displacement device 52 is set on the fifth sliding table 532, so that the fifth displacement device 53 can drive the beak knotting machine 51 to move left and right. After the beak knotting machine 51 moves to the predetermined position, it moves forward under the push of the fourth displacement device 52 to approach the rope 23 for knotting the parallel rope 23. The actuation assembly 54 includes an actuating rod 541 and a rod displacement device 542. The actuating rod 541 is a cylindrical rod with a groove on its surface. The rod displacement device 542 is connected to the inner wall of the housing 1. The rod displacement device 542 uses an existing single-axis slide to drive the actuating rod 541 to move left and right. When the actuating rod 541 is in the initial position, it is located to the left of the first displacement device 25. When working, it moves to the right of the first displacement device 25. The actuating rod 541 can move the rope 23 located to the left of the first displacement device 25 to the right of the first displacement device 25, so that the rope 23 forms two parallel segments for easy knotting. After completing the work, the actuating rod 541 returns to the initial position.

[0067] like Figure 7 , Figure 8 , Figure 9 , Figure 21 and Figure 22 As shown, the shearing assembly 6 includes scissors 61, a third gripper 62, and a sixth displacement device 63. Scissors 61 are existing electric scissors used to cut rope 23. The third gripper 62 is an electric gripper used to hold the knotted rope 23. The sixth displacement device 63 drives the scissors 61 and the third gripper 62 to move back and forth. When moving forward, the scissors 61 and the third gripper 62 approach the rope 23. The sixth displacement device 63 is connected to a fifth displacement device 53, which can drive the sixth displacement device 63 to move left and right, thereby adjusting the left and right positions of the scissors 61 and the third gripper 62. When the sixth displacement device 63 drives the third gripper 62 to move backward, the knotted rope 23 held by the third gripper 62 causes the bundled fast food box to move backward and fall into the second drawer 8.

[0068] like Figure 7As shown, a fourth sensor 94 is installed inside the box 1. The position of the fourth sensor 94 corresponds to the first drawer 7. The fourth sensor 94 is an existing distance sensor used to detect whether the residue in the first drawer 7 has reached a predetermined height. A fifth sensor 95 is installed on the inner wall of the box 1. The position of the fifth sensor 95 corresponds to the second drawer 8. The fifth sensor 95 is an existing distance sensor used to detect whether the fast food boxes in the second drawer 8 have reached a predetermined height. When the fast food boxes are stacked to the height of the fifth sensor 95, the sensor will be triggered (for example, two fast food boxes are stacked to the height of the fifth sensor 95). The housing 1 is equipped with a self-locking door 12 and a self-locking push rod 13 corresponding to the dispensing port 11. The self-locking door 12 is a rectangular piece corresponding to the size of the dispensing port 11. The self-locking push rod 13 is an electric push rod that can drive the self-locking door 12 to move up and down. The self-locking push rod 13 drives the self-locking door 12 to move, thereby opening or closing the dispensing port 11. The housing 1 is also equipped with a control device (not shown in the figure). The control device uses an existing PLC controller. The control device, along with the self-locking push rod 13, the box-passing assembly 2, the box-pressing assembly 3, the knotting assembly 5, and the shearing and dragging assembly 6, are all... Electrical connections are used to control the operation of multiple displacement devices, multiple grippers, the eagle-beak knotting machine 51, scissors 61, and other components. The control device is electrically connected to the first sensor 91, the second sensor 92, the third sensor 93, the fourth sensor 94, and the fifth sensor 95 to receive signals from the five sensors. Based on the received signals, the control device controls the operation of the box-threading assembly 2, the box-pressing assembly 3, the knotting assembly 5, and the shearing and dragging assembly 6, or issues an alarm. When an alarm is issued, it can remind staff to replace the rope 23, remove the first drawer 7 to handle the residue, or remove the second drawer 8 to handle the fast food box. The control device controls the operation of the self-locking push rod 13 based on the signals from the multiple sensors, thereby controlling the opening or closing of the dispensing port 11. Dispensing is not allowed in any of the following situations: 1) the first drawer 7 is full of food residue; 2) the second drawer 8 is full of fast food box; 3) the packing rope is used up; 4) during the squeezing and packing process. At this time, a red light will illuminate, and the control device will connect to an external monitoring system via a signal line. In the first three situations, management signals can be sent to the property management or sanitation department to achieve information management.

[0069] This embodiment also provides a fast food box recycling method, which uses the above-mentioned pressure-type fast food box automatic recycling and packaging device, including the following steps:

[0070] S1. The fast food box is placed into the box body 1 through the delivery port 11 and is located on the lower support plate 21. The first sensor 91 senses the fast food box. The threading needle 22 is in the initial position, and the rope 23 is connected to the hook 221 of the threading needle 22.

[0071] S2, the first displacement device 25 drives the threading needle 22 to move upward, the threading needle 22 passes through the fast food box and upward through the upper pressure plate 31, and drives the rope 23 to move, such as Figure 11 As shown;

[0072] S3, the second gripper 34 clamps the threading needle 22, the first gripper 26 releases the threading needle 22, and the third displacement device 33 moves the second displacement device 32 and the upper pressure plate 31 to above the transfer groove 4. At the same time, the rope 23 is stretched. Figure 12 As shown;

[0073] S4. The second displacement device 32 moves the upper pressure plate 31 downward, pressing the fast food box onto the pressure plate 41. At the same time, the rope 23 is stretched. Figure 13 As shown;

[0074] S5. After the fast food box is placed on the pressure plate 41, the second displacement device 32 drives the upper pressure plate 31 to move upward, and the third displacement device 33 drives the second displacement device 32 and the upper pressure plate 31 to the initial position, such as... Figure 14 and Figure 15 As shown, at this time the fast food box is pulled and tilted, and the residue inside the fast food box leaks from the gap between the pressure plate 41 and the side plate 42 and the third through hole into the first drawer 7 below.

[0075] S6. The first gripper 26 clamps the threading needle 22, the second gripper 34 releases the threading needle 22, and the first displacement device 25 moves the threading needle 22 downward to the initial position to wait for the next fast food box. Figure 16 As shown;

[0076] S7. Fast food boxes are continuously fed into the inlet 11. Under the operation of the box-passing component 2 and the box-pressing component 3, the fast food boxes are continuously stacked to form a fast food box package, such as... Figure 17 As shown;

[0077] S8. When the third sensor 93 on the transfer trough 4 detects that the stack of fast food boxes has reached the predetermined height, the knotting component 5 starts to work. At this time, the threading needle 22 is in the initial position, the rope 23 forms the first parallel segment, and the fourth displacement device 52 drives the beak knotting machine 51 to move forward. The beak knotting machine 51 knots the first parallel segment of rope 23 for the first time to form the first knot 231, thereby binding the fast food boxes in the transfer trough 4. Figure 18 and Figure 19 As shown;

[0078] S9. After the first knot is tied, the first displacement device 25 moves the threading needle 22 downwards, and the head of the rope 23 disengages from the threading needle 22. However, the rope 23 as a whole remains connected to the fast food box bag through the first knot 231. After the head of the rope 23 disengages, the first displacement device 25 moves the threading needle 22 upwards to the initial position. Since the rope 23 is in the position corresponding to the threading needle 22, the hook 221 of the threading needle 22 re-hooks the rope 23. Figure 20 As shown;

[0079] S10, the actuating component 54 moves the rope 23 near the end of the rope winder 24 to the other end to form a second parallel segment. The fifth displacement device 53 drives the beak knotting machine 51 to move to the second parallel segment of the rope 23. The beak knotting machine 51 knots the rope 23 in the second parallel segment a second time to form a second knot 232. Figure 21 and Figure 22 As shown; at this time, rope 23 is connected to the hook 221 of the needle 22 via the second knot 232;

[0080] S11, the sixth displacement device 63 drives the scissors 61 and the third gripper 62 to move forward. The third gripper 62 clamps the rope 23 with the first knot 231. The scissors 61 cuts the rope 23 between the first knot 231 and the second knot 232. The rope 23 with the first knot 231 and the fast food box bag form a bundle, such as... Figure 23 As shown, after the second knot is tied, the actuating component 54 returns to the initial position to the left. Since the rope 23 between the first knot 231 and the second knot 232 is cut, the second knot 232 is connected to the needle hook 221. The rope 23 with the second knot 232 is restored to a straight shape and connected to the threading needle 22 under the tightening action of the rope winder 24.

[0081] S12, the sixth displacement device 63 drives the third gripper 62 to move backward, the third gripper 62 pulls the bundle to fall into the second drawer 8; the rope 23 on the rope winder 24 forms a new rope knot due to the second knot 232, the pull needle 22 hooks the rope knot of the rope 23 in the initial position, waiting for the new fast food box to be put in.
