Description

Technical Field

[0001] The invention relates to the technical field of plastic lunch box production, and in particular to a defective plastic lunch box conveying and collecting device and method thereof. Background Art

[0002] Plastic lunch boxes are widely used in the modern catering industry because of their lightness, durability, and easy cleaning. Raw material preparation is the first step in the production of plastic lunch boxes, which mainly includes the purchase, inspection, and storage of the required raw materials. The raw materials are usually plastic materials such as polypropylene (PP) and polyethylene (PE), and it is necessary to ensure that they meet the production requirements, such as purity, viscosity, stability, etc. According to the product formula and process requirements, the raw materials are mixed in a certain proportion, and the raw materials are heated and stirred by a mixer to make them evenly mixed and reach a certain viscosity. Injection molding is the core step in the production of plastic lunch boxes. The molded plastic lunch boxes need to go through a cooling process to solidify them and have a certain strength and hardness. In order to improve the durability and aesthetics of the plastic lunch boxes, surface treatment is usually required. After the plastic lunch boxes are produced, they need to be quality inspected and defective products are removed from the products produced. During the production process, defective products are often generated due to problems with raw materials, production processes, equipment or operations, and these defective products cannot enter the market. In order to avoid wasting resources, manufacturers usually collect these defective products, and then put them into scrap equipment to break them into pieces, and re-prepare them together with the raw materials. In the actual processing process, the inventor found that when collecting defective lunch boxes, since the lunch boxes are pushed into the collection frame through a conveyor belt or a pushing mechanism (including a cylinder and a pushing pad), the lunch boxes are often piled up in the collection frame, and the space utilization rate in the collection frame is low. In addition, when the subsequent staff organizes the defective lunch boxes, the workload of the staff will also increase.

The sensing element is located on the motion trajectory of the touch shaft, and the sensing element is electrically connected to the plate-shaped electromagnetic mechanism.

[0013] A method for using a defective plastic lunch box conveying and collecting device, specifically comprising the following steps: S1. The production mechanism discharges the defective lunch boxes produced onto the conveying mechanism, and conveys the defective lunch boxes to the pushing mechanism under the action of the conveying mechanism. At this time, the pushing mechanism pushes the lunch boxes onto the supporting roller mechanism, and the plate-shaped electromagnetic mechanism is energized to generate an attractive force on the side of the clamping plate frame A and the clamping plate frame B with a magnetic surface. The clamping plate frame A and the clamping plate frame B move relative to each other, that is, move in the direction of the plate-shaped electromagnetic mechanism. The clamping plate frame A and the clamping plate frame B clamp the ends of the defective lunch boxes. During the initial movement, the telescopic shafts on one side of the clamping plate frame A and the clamping plate frame B will pass through the inclined surface of the guide plate frame. After clamping the defective lunch boxes, the annular electromagnetic panel is energized to generate an attractive force on the magnetic sleeve. The magnetic sleeve contacts the annular electromagnetic panel, and then the servo motor rotates forward, and the output end of the servo motor drives the drive shaft through the pulley and belt. The body rotates, and the driving shaft drives the magnetic sleeve to rotate through the annular electromagnetic panel. Since the magnetic sleeve is slidably connected to the transmission shaft, the transmission shaft drives the connecting shaft to rotate, so that the connecting shaft drives the supporting roller mechanism to adjust the angle. At this time, the clamping plate frame A and the clamping plate frame B will drive the defective lunch box to move upward. After the angle of the supporting roller mechanism is adjusted, the supporting roller mechanism is not directly under the defective lunch box. Then the annular electromagnetic panel is powered off, and the servo motor reverses. Under the action of the screw rod, the driving slider slides on the upper limit of the guide shaft, and under the action of the connecting rod frame, the sliding sleeve, the axial fixing part, the supporting shaft, the extension plate frame, the magnet slider, the rotating shaft, the connecting bracket, the clamping outer frame, the clamping plate frame A and the clamping plate frame B and other components are synchronously lowered, thereby realizing the stacking of defective lunch boxes.

[0014] S2. When the opening of the defective lunch box is facing downward, the end of the defective lunch box contacts the surface of the supporting roller mechanism. At this time, the clamping plate frame A and the clamping plate frame B cannot clamp the end of the defective lunch box. First, the block electromagnetic mechanism is energized to generate a repulsive force on the magnet slider, and the spring mechanism is squeezed by the magnet slider. At this time, the meshing gear on the rotating shaft will contact the meshing tooth row and be meshed by the meshing tooth row, and then the rotating shaft rotates. In the present invention, the rotation angle of the rotating shaft is 180°, and then during the rotation of the rotating shaft, the connecting bracket will drive the clamping outer frame and the straw mechanism to rotate, and the clamping plate frame A and the clamping plate frame B in the clamping outer frame will rotate synchronously with it, and the magnet slider continues to move. Under the action of the rotating shaft and the connecting bracket, the straw mechanism contacts the surface of the defective lunch box and ventilates. The straw mechanism fixes the defective lunch box, and then the annular electromagnetic panel is energized to generate an attractive force on the magnetic sleeve, and the magnetic sleeve contacts the annular electromagnetic panel. Then the servo motor rotates forward, and the cycle is repeated. In the above operation, the support roller mechanism is adjusted in angle, and the support roller mechanism is not directly below the defective lunch box. Then the arc electromagnetic assembly is energized to generate an attractive force on the magnetic surface of the movable sleeve, and the movable sleeve moves in the direction of the arc electromagnetic assembly. During this process, the rolling ball on the movable sleeve will move along the trajectory of the spiral groove, that is, the movable sleeve rotates 180°. Due to the sliding connection between the movable sleeve and the support shaft body, the support shaft body rotates synchronously with it, so that under the action of the magnet slider, the rotating shaft body, and the connecting bracket, the straw mechanism drives the defective lunch box to rotate 180°. At this time, the opening of the defective lunch box faces upward, and then the block electromagnetic mechanism is powered off, and the magnet slider is restored to its initial position under the action of the spring mechanism, and the meshing gear on the rotating shaft body is restored to its initial position under the action of the meshing gear row, and the corresponding arc electromagnetic assembly is also powered off. Under the action of the spring body, the movable sleeve drives the support shaft body and the mechanical components thereon back to the initial position, and then repeats the S1 operation.

[0015] S3. When the clamping plate frame A and the clamping plate frame B need to be repositioned, the plate-shaped electromagnetic mechanism is energized to generate an attractive force on the clamping plate frame A and the clamping plate frame B, so that the clamping plate frame A and the clamping plate frame B move to the closest point. At this time, the circular magnetic blocks on the telescopic shafts of the two will move to the force-applying magnetic blocks, and the force-applying magnetic blocks will generate an attractive force on them, that is, the telescopic shaft in a compressed state is subjected to the force to enter the lateral area, and the reset spring is in a stretched state. At this time, the guide plate frame is not on the movement trajectory of the telescopic shaft, and then under the action of the constant force spring, the telescopic shaft returns in the reciprocating area and leaves the force-applying magnetic block. When it moves to the intersection of the reciprocating area and the disconnection area, the telescopic shaft will return to the initial position along the inclined surface of the disconnection area under the action of the reset spring. At this time, the clamping plate frame A and the clamping plate frame B return to their initial positions.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a clamping assembly to limit the defective lunch boxes, and under the action of the screw rod, the clamping assembly drives the defective lunch boxes to adjust their positions, so that stacking can be achieved in the collection mechanism, and the support roller mechanism can be used to support the lunch boxes pushed out by the pushing mechanism, so that the clamping assembly can clamp the defective lunch boxes, and at the same time, under the action of the transmission mechanism, the support roller mechanism can be adjusted in angle. Through the structural design of the present invention, the defective lunch boxes can be effectively stacked, the utilization of the space of the collection mechanism is improved, and the staff does not need to sort the defective lunch boxes; The spacing between the guide plate frames in the present invention is larger than the outer diameter of the telescopic shaft, so that the telescopic shaft can be adjusted between the guide plate frames, so that the clamping plate frame A and the clamping plate frame B can be appropriately adjusted in the clamping position of the defective lunch box, thereby avoiding the situation where the lunch box is difficult to enter between the clamping plate frame A and the clamping plate frame B, and avoiding damage to the defective lunch box caused by excessive instantaneous force on the other hand.

When the annular electromagnetic panel 731 is energized, it generates an attractive force on the magnetic sleeve 72. Further, a sliding ball or pulley can be installed on the inner wall of the magnetic sleeve 72 to reduce the friction between the magnetic sleeve 72 and the outer wall of the transmission shaft body 71, and then when the annular electromagnetic panel 731 is energized, The magnetic sleeve 72 is attracted to each other, and the magnetic sleeve 72 contacts the annular electromagnetic panel 731. At this time, the servo motor 51 is started, and the output end can drive the drive shaft 73 to rotate through the pulley 74 and the belt. The drive shaft 73 drives the magnetic sleeve 72 to rotate through the annular electromagnetic panel 731. Since the magnetic sleeve 72 is slidably connected to the transmission shaft 71, the transmission shaft 71 drives the connecting shaft 61 to rotate, so that the connecting shaft 61 drives the supporting roller mechanism 6 to adjust the angle. It should be noted that the multiple rollers on the supporting roller mechanism 6 are rotatably connected to the inner wall, so that the friction between the defective lunch box and the roller is relatively small; it also includes a clamping assembly 8 symmetrically arranged above the supporting roller mechanism 6, and the clamping assembly 8 is used to clamp the end of the defective lunch box; the clamping assembly 8 is connected to the driving slider 53 through a connecting piece 9; The connecting member 9 includes a connecting rod frame 91 fixedly connected to both ends of the driving slider 53, and a sliding sleeve 92 is fixedly installed at each end of the connecting rod frame 91.

A spiral groove 931 is arranged inside the shaft-shaped fixing member 93. The rolling ball 121 slides within the spiral groove 931. In the initial state, the rolling ball 121 is located at the initial end of the spiral groove 931. When the arc-shaped electromagnetic component 11 is energized, an attraction force is generated on the magnetic surface of the movable sleeve 12. At this time, the rolling ball 121 on the movable sleeve 12 moves from the initial end to the end of the spiral groove 931. The rolling ball 121 moves from the initial end to the end of the spiral groove 931. In the process of changing from the initial end to the end end, the movable sleeve 12 will rotate, and the rotation angle is 180°.

A slide rail 83 is provided on one side of the clamping plate frame A81 and the clamping plate frame B82, and a telescopic shaft body 84 in a compressed state is installed in the slide rail 83. The telescopic shaft body 84 can slide within the slide rail 83. A reset spring 85 is connected between the telescopic shaft body 84 and the inner wall of the slide rail 83. A plurality of guide plate frames 86 are symmetrically fixedly installed on the inner wall of the clamping outer frame 902, and the guide plate frames 86 are located on the movement trajectory of the telescopic shaft body 84; constant force springs 87 are connected between the clamping plate frame A81 and the clamping plate frame B82 and the inner wall of the clamping outer frame 902; the side of the clamping plate frame A81 and the clamping plate frame B82 that are close to each other is made of magnetic material, and a plate-shaped electromagnetic mechanism 904 is fixedly installed in the middle area of ​​the clamping outer frame 902. When the plate-shaped electromagnetic mechanism 904 is energized, the clamping plate frame A81 and the clamping plate frame B82 have a magnetic surface on one side to generate an attractive force, wherein the induction element is electrically connected to the plate-shaped electromagnetic mechanism 904; it should be noted that the distance between the guide plate frames 86 is greater than the outer diameter of the end of the telescopic shaft 84, and the inner wall of the clamping outer frame 902 is symmetrically provided with an adjustment groove 905 for limiting the end of the telescopic shaft 84, and the adjustment groove 905 includes a lateral area 906, a reciprocating area 907 and a disconnection area 908, wherein the lateral area 906 is closer to the plate-shaped electromagnetic mechanism 904 relative to the disconnection area 908, and the end of the disconnection area 908 away from the reciprocating area 907 is inclined, and a circular magnetic block 88 is fixedly installed on the outer wall of each telescopic shaft 84, and a force-applying magnetic block 909 is symmetrically installed on the inner wall of one side of the clamping outer frame 902, and the force-applying magnetic block 909 coincides with the center line of the lateral area 906; Step 1: The opening of the defective lunch box faces upward; the production mechanism 2 discharges the produced defective lunch box onto the conveying mechanism 3, and under the action of the conveying mechanism 3, the defective lunch box is conveyed to the pushing mechanism 4, at which time the pushing mechanism 4 pushes the lunch box onto the supporting roller mechanism 6. It should be noted that, under normal circumstances, the end of the defective lunch box (i.e., the place where the lunch box cover is closed) is located at the clamping plate frame A81 and the clamping plate frame B82. At this time, the plate-shaped electromagnetic mechanism 904 is started, and the plate-shaped electromagnetic mechanism 904 is energized to clamp the clamping plate frame A81 and the clamping plate The side of the frame B82 with a magnetic surface generates an attractive force, and the clamping plate frame A81 and the clamping plate frame B82 move relative to each other, that is, move in the direction of the plate-shaped electromagnetic mechanism 904, and the clamping plate frame A81 and the clamping plate frame B82 clamp the end of the defective lunch box. During the initial movement (that is, the clamping plate frame A81 and the clamping plate frame B82 are the farthest apart), the telescopic shaft 84 on one side of the clamping plate frame A81 and the clamping plate frame B82 will pass through the inclined surface of the guide plate frame 86. When it moves to the position of clamping the defective lunch box, the clamping plate The frame A81 and the clamping plate frame B82 will remain stationary, and the touching shaft will contact the sensing element, and then the sensing element will control the plate-shaped electromagnetic mechanism 904 to cut off the power. Since the distance between the guide plate frames 86 is greater than the outer diameter of the end of the telescopic shaft 84, the clamping plate frame A81 and the clamping plate frame B82 will adjust their positions within a certain range, that is, the end of the telescopic shaft 84 will adjust its position between the guide plate frames 86. The function of this design is: when the clamping plate frame A81 and the clamping plate frame B82 remain stationary in the clamping position, It is difficult for subsequent lunch boxes to overcome the friction and enter between the clamping plate frame A81 and the clamping plate frame B82. If they are restored to the initial position (i.e., the clamping plate frame A81 and the clamping plate frame B82 are the farthest apart), they need to move the maximum distance each time, and the instantaneous force when they come into contact with the defective lunch box is also relatively large, which is easy to cause damage to the defective lunch box. On the basis of the clamping position, a corresponding small-range position adjustment is made, which is convenient for quickly clamping the defective lunch box on the one hand, and on the other hand, it also avoids damage to the defective lunch box caused by excessive instantaneous force;After the defective lunch box is clamped, the annular electromagnetic panel 731 is energized to generate an attractive force on the magnetic sleeve 72, and the magnetic sleeve 72 contacts the annular electromagnetic panel 731. Then the servo motor 51 rotates forward, and the output end of the servo motor 51 drives the drive shaft 73 to rotate through the pulley 74 and the belt. The drive shaft 73 drives the magnetic sleeve 72 to rotate through the annular electromagnetic panel 731. Since the magnetic sleeve 72 is slidably connected to the transmission shaft 71, the transmission shaft 71 drives The movable connecting shaft 61 rotates so that the connecting shaft 61 drives the supporting roller mechanism 6 to adjust the angle. At this time, under the action of the screw rod 52, the driving slider 53 slides upward at the upper limit of the guide shaft 54, and under the action of the connecting rod frame 91, the sliding sleeve 92, the axial fixing member 93, the supporting shaft 94, the extension plate frame 95, the magnet slider 97, the rotating shaft 90, the connecting bracket 901, the clamping outer frame 902, the clamping plate frame A81 and the clamping plate frame B82 are moved. The components such as the support plate frame A81 and the support plate frame B82 perform synchronous upward movement, and then the defective lunch box is driven to perform upward movement under the action of the clamping plate frame A81 and the clamping plate frame B82. After the angle of the support roller mechanism 6 is adjusted, the support roller mechanism 6 is not directly below the defective lunch box. Then the annular electromagnetic panel 731 is powered off, and the servo motor 51 is reversed. Under the action of the screw rod 52, the driving slider 53 slides on the upper limit of the guide shaft body 54, and under the action of the connecting rod frame 91, the sliding sleeve 92, the axial fixing member 93, the supporting shaft body 94, the extension plate frame 95, the magnet slider 97, the rotating shaft body 90, the connecting bracket 901, the clamping outer frame 902, the clamping plate frame A81 and the clamping plate frame B82 and other components perform synchronous downward movement, and the clamped defective lunch box is sent to the collecting mechanism 13 below. It is further explained that the collecting mechanism 13 is a prior art structure, and the present invention does not describe it too much. In order to facilitate the stacking of defective lunch boxes in the collecting mechanism 13, the collecting mechanism 13 can be as shown in the attached; Fig.14 It is arranged that a plurality of hydraulic cylinders 14 are used to control the position adjustment of the collecting mechanism 13 in the frame. It is also possible to arrange a plurality of collecting mechanisms 13. By switching the collecting mechanisms 13, different kinds of defective lunch boxes can be collected and stacked.

[0021] Step 2: Continuing from the above, when the opening of the defective lunch box is facing downward, the end of the defective lunch box (the place where the lunch box is covered) will contact the surface of the supporting roller mechanism 6. At this time, the clamping plate frame A81 and the clamping plate frame B82 cannot clamp the end of the defective lunch box. First, the block electromagnetic mechanism 99 is energized to generate a repulsive force on the magnet slider 97, and the spring mechanism 98 is squeezed by the magnet slider 97. At this time, the meshing gear 10 on the rotating shaft 90 will contact the meshing tooth row 951 and be meshed by the meshing tooth row 951, so that the rotating shaft 90 rotates. In the present invention, the rotation angle of the rotating shaft 90 is 180°, and then when the rotating shaft 90 is rotated, the meshing gear 10 on the rotating shaft 90 is rotated. During the rotation of the shaft 90, the connecting bracket 901 will drive the clamping outer frame 902 and the straw mechanism 903 to rotate, and the clamping plate frame A81 and the clamping plate frame B82 in the clamping outer frame 902 will rotate synchronously with it. It should be noted that the clamping plate frames A81 and B82 may contact the defective lunch boxes during the rotation, but because the lunch boxes are made of plastic and have a certain deformation ability, the rotation of the clamping plate frames A81 and B82 will not be hindered. When the straw mechanism 903 rotates to the vicinity of the defective lunch box, since the straw mechanism 903 is close to the rotating shaft 9 relative to the clamping assembly 8 0, and then at this time, the straw mechanism 903 is at a certain distance from the surface of the defective lunch box, and the magnet slider 97 continues to move. Under the action of the rotating shaft 90 and the connecting bracket 901, the straw mechanism 903 contacts the surface of the defective lunch box, and the ventilation adsorbs the defective lunch box. The straw mechanism 903 fixes the defective lunch box, and then the annular electromagnetic panel 731 is energized to generate an attractive force on the magnetic sleeve 72, and the magnetic sleeve 72 contacts the annular electromagnetic panel 731. Then the servo motor 51 rotates forward, and the above operation is repeated. The support roller mechanism 6 adjusts the angle, and the support roller mechanism 6 is not directly below the defective lunch box, and then After that, the arc-shaped electromagnetic assembly 11 is energized to generate an attraction force on the magnetic surface of the movable sleeve 12, and the movable sleeve 12 moves in the direction of the arc-shaped electromagnetic assembly 11. During this process, the rolling ball 121 on the movable sleeve 12 moves along the trajectory of the spiral groove 931, that is, the movable sleeve 12 rotates 180°. Since the movable sleeve 12 is slidably connected to the support shaft 94, the support shaft 94 rotates synchronously therewith, so that under the action of the magnet slider 97, the rotating shaft 90, and the connecting bracket 901, the straw mechanism 903 drives the defective lunch box to rotate 180°, and the opening of the defective lunch box faces upward.Assuming that the surface of the defective lunch box is uneven when it is designed, or there are defects on the surface of the defective lunch box, such as convex surface during injection molding, or holes on the surface, during adsorption, although the straw mechanism 903 can provide a certain adsorption force for the defective lunch box, it is necessary to overcome the friction resistance between the defective lunch boxes during the stacking process, so the straw mechanism 903 may be separated from the defective lunch box due to the friction resistance. Therefore, after adjusting the angle of the defective lunch box, the present invention preferably adopts the clamping plate frame A81 The defective lunch boxes are stacked with the clamping plate frame A81 and the clamping plate frame B82, and then when the clamping plate frame A81 and the clamping plate frame B82 are restored to clamp the defective lunch boxes, the servo motor 51 rotates forward first, and under the action of the above components, the straw mechanism 903 drives the defective lunch boxes to move upward, ensuring that the defective lunch boxes are located above the supporting roller mechanism 6 and there is a certain distance, and then the annular electromagnetic panel 731 is energized to generate an attractive force on the magnetic sleeve 72, and the magnetic sleeve 72 contacts the annular electromagnetic panel 731, and then the servo motor 51 rotates forward. The servo motor 51 reverses, and the output end of the servo motor 51 drives the drive shaft 73 to rotate through the pulley 74 and the belt. The drive shaft 73 drives the magnetic sleeve 72 to rotate through the annular electromagnetic panel 731. Since the magnetic sleeve 72 is slidably connected to the transmission shaft 71, the transmission shaft 71 drives the connecting shaft 61 to rotate, so that the connecting shaft 61 drives the supporting roller mechanism 6 to rotate, so that the supporting roller mechanism 6 moves directly under the lunch box. Then the annular electromagnetic panel 731 is powered off, and the servo motor 51 is controlled to continue to reverse, so that the straw mechanism 903 drives the lunch box to move to contact with the supporting roller mechanism 6. Then the block electromagnetic mechanism 99 is powered off, and the magnet slider 97 is restored to the initial position under the action of the spring mechanism 98, and the rotating shaft 90 is restored to the initial position through the meshing gear 10 thereon under the action of the meshing gear row 951. The corresponding arc-shaped electromagnetic assembly 11 is also powered off. Under the action of the spring body 122, the moving sleeve 12 drives the supporting shaft 94 and the mechanical components thereon to return to the initial position; Step 3: When the clamping plate frame A81 and the clamping plate frame B82 need to be repositioned, the plate-shaped electromagnetic mechanism 904 is energized to generate an attractive force on the clamping plate frame A81 and the clamping plate frame B82, so that the clamping plate frame A81 and the clamping plate frame B82 move to the closest position. At this time, the circular magnetic block 88 on the telescopic shaft 84 of the two will move to the force-applying magnetic block 909 and the lateral area 906, and the force-applying magnetic block 909 will generate an attractive force on them, that is, the telescopic shaft 84 in the compressed state is subjected to the force and enters the reciprocating area In the area 907 (the reset spring 85 is in a stretched state), the guide plate frame 86 is not on the movement trajectory of the telescopic shaft 84, and then under the action of the constant force spring 87, the telescopic shaft 84 returns in the reciprocating area 907 and leaves the force magnetic block 909. When it moves to the intersection of the reciprocating area 907 and the disconnection area 908, the telescopic shaft 84 returns to its initial position along the inclined surface of the disconnection area 908 under the action of the reset spring 85. At this time, the clamping plate frame A81 and the clamping plate frame B82 return to their initial positions.

[0022] A method for using a defective plastic lunch box conveying and collecting device, specifically comprising the following steps: S1, the production mechanism 2 discharges the defective lunch boxes produced to the conveying mechanism 3, and under the action of the conveying mechanism 3, the defective lunch boxes are conveyed to the pushing mechanism 4. At this time, the pushing mechanism 4 pushes the lunch boxes to the supporting roller mechanism 6, and the plate-shaped electromagnetic mechanism 904 is energized to generate an attraction force on the side of the clamping plate frame A81 and the clamping plate frame B82 with a magnetic surface, and the clamping plate frame A81 and the clamping plate frame B82 move relative to each other, that is, move in the direction of the plate-shaped electromagnetic mechanism 904, and the clamping plate frame A81 The end of the defective lunch box is clamped by the clamping plate frame B82. During the initial movement, the telescopic shaft 84 on one side of the clamping plate frame A81 and the clamping plate frame B82 passes through the inclined surface of the guide plate frame 86. After the defective lunch box is clamped, the annular electromagnetic panel 731 is energized to generate an attractive force on the magnetic sleeve 72. The magnetic sleeve 72 contacts the annular electromagnetic panel 731, and then the servo motor 51 rotates forward. The output end of the servo motor 51 drives the drive shaft 73 to rotate through the pulley 74 and the belt. The driving shaft 73 drives the magnetic sleeve 72 to rotate through the annular electromagnetic panel 731. Since the magnetic sleeve 72 is slidably connected with the transmission shaft 71, the transmission shaft 71 drives the connecting shaft 61 to rotate, so that the connecting shaft 61 drives the supporting roller mechanism 6 to adjust the angle. At this time, the clamping plate frame A81 and the clamping plate frame B82 will drive the defective lunch box to move upward. After the angle of the supporting roller mechanism 6 is adjusted, the supporting roller mechanism 6 is not directly below the defective lunch box. Then the annular The electromagnetic panel 731 is powered off, and the servo motor 51 reverses. Under the action of the screw rod 52, the driving slider 53 slides on the upper limit of the guide shaft 54, and under the action of the connecting rod frame 91, the sliding sleeve 92, the axial fixing part 93, the supporting shaft 94, the extension plate frame 95, the magnet slider 97, the rotating shaft 90, the connecting bracket 901, the clamping outer frame 902, the clamping plate frame A81 and the clamping plate frame B82 and other components are synchronously lowered, thereby realizing the stacking of defective lunch boxes.

[0023] S2. When the opening of the defective lunch box faces downward, the end of the defective lunch box contacts the surface of the supporting roller mechanism 6. At this time, the clamping plate frame A81 and the clamping plate frame B82 cannot clamp the end of the defective lunch box. First, the block electromagnetic mechanism 99 is energized to generate a repulsive force on the magnet slider 97. The spring mechanism 98 is squeezed by the magnet slider 97. At this time, the meshing gear 10 on the rotating shaft body 90 contacts the meshing tooth row 951 and is meshed by the meshing tooth row 951, thereby driving the rotating shaft body 90 to rotate. In the present invention, the rotation angle of the rotating shaft body 90 is 180°, and then the rotating shaft body 90 is rotated. During the rotation of the body 90, the connecting bracket 901 will drive the clamping outer frame 902 and the straw mechanism 903 to rotate, and the clamping plate frame A81 and the clamping plate frame B82 in the clamping outer frame 902 will rotate synchronously with it, and the magnet slider 97 continues to move. Under the action of the rotating shaft 90 and the connecting bracket 901, the straw mechanism 903 contacts the surface of the defective lunch box, ventilates, and fixes the defective lunch box. Then, the annular electromagnetic panel 731 is energized to generate an attractive force on the magnetic sleeve 72, and the magnetic sleeve 72 contacts the annular electromagnetic panel 731. Then, the servo motor 51 is positively rotated. The supporting roller mechanism 6 is rotated, and some operations in S1 are repeated. The supporting roller mechanism 6 is adjusted in angle, and the supporting roller mechanism 6 is not directly below the defective lunch box. Then, the arc-shaped electromagnetic component 11 is energized to generate an attraction force on the magnetic surface of the movable sleeve 12, and the movable sleeve 12 moves in the direction of the arc-shaped electromagnetic component 11. During this process, the rolling ball 121 on the movable sleeve 12 moves along the trajectory of the spiral groove 931, that is, the movable sleeve 12 rotates 180°. Since the movable sleeve 12 is slidably connected to the supporting shaft 94, the supporting shaft 94 rotates synchronously therewith, thereby 97. Under the action of the rotating shaft 90 and the connecting bracket 901, the straw mechanism 903 drives the defective lunch box to rotate 180°. At this time, the opening of the defective lunch box faces upward, and then the block electromagnetic mechanism 99 is powered off. The magnet slider 97 is restored to the initial position under the action of the spring mechanism 98, and the rotating shaft 90 is restored to the initial position through the meshing gear 10 thereon under the action of the meshing gear row 951. The corresponding arc-shaped electromagnetic component 11 is also powered off. Under the action of the spring body 122, the movable sleeve 12 drives the supporting shaft 94 and the mechanical parts thereon back to the initial position, and then repeats the S1 operation.

[0024] S3. When the clamping plate frame A81 and the clamping plate frame B82 need to readjust their positions, the plate-shaped electromagnetic mechanism 904 is energized to generate an attraction force on the clamping plate frame A81 and the clamping plate frame B82, so that the clamping plate frame A81 and the clamping plate frame B82 move to the closest position. At this time, the circular magnetic block 88 on the telescopic shaft 84 of the two will move to the force-applying magnetic block 909 and the lateral area 906, and the force-applying magnetic block 909 will generate an attraction force on them, that is, the telescopic shaft 84 in the compressed state is subjected to the force to enter the reciprocating area. In the domain 907, the reset spring 85 is in a stretched state. At this time, the guide plate frame 86 is not on the movement trajectory of the telescopic shaft 84. Then, under the action of the constant force spring 87, the telescopic shaft 84 returns in the reciprocating area 907 and leaves the force magnetic block 909. When it moves to the intersection of the reciprocating area 907 and the disconnection area 908, the telescopic shaft 84 will return to the initial position along the inclined surface of the disconnection area 908 under the action of the reset spring 85. At this time, the clamping plate frame A81 and the clamping plate frame B82 return to their initial positions.

First, the block electromagnetic mechanism (99) is energized to generate a repulsive force on the magnet slider (97). The spring mechanism (98) is squeezed by the magnet slider (97). At this time, the meshing gear (10) on the rotating shaft (90) contacts the meshing gear row (951) and is meshed by the meshing gear row (951), thereby driving the rotating shaft (90) to rotate. The connecting bracket (901) then drives the clamping outer frame (902) and The straw mechanism (903) rotates, and the clamping plate frame A (81) and the clamping plate frame B (82) in the clamping outer frame (902) rotate synchronously therewith. The magnet slider (97) continues to move, and under the action of the rotating shaft (90) and the connecting bracket (901), the straw mechanism (903) contacts the surface of the defective lunch box, ventilates, and fixes the defective lunch box. Then, the annular electromagnetic panel (731) is energized to generate an attractive force on the magnetic sleeve (72). The magnetic sleeve (72) contacts the annular electromagnetic panel (731), and then the servo motor (51) rotates forward. The partial operation in S1 is repeated, and the supporting roller machine is supported. The structure (6) is adjusted in angle, the supporting roller structure (6) is not directly below the defective lunch box, and then the arc-shaped electromagnetic assembly (11) is energized to generate an attractive force on the magnetic surface of the movable sleeve (12), and the movable sleeve (12) moves in the direction of the arc-shaped electromagnetic assembly (11). During this process, the rolling ball (121) on the movable sleeve (12) moves along the trajectory of the spiral groove body (931), that is, the movable sleeve (12) rotates 180°. Since the movable sleeve (12) is slidably connected to the supporting shaft body (94), the supporting shaft body (94) rotates synchronously therewith, thereby rotating the movable sleeve (12) and the rotating shaft body (97). 90), under the action of the connecting bracket (901), the straw mechanism (903) drives the defective lunch box to rotate 180 degrees, at which time the opening of the defective lunch box faces upward, and then the block electromagnetic mechanism (99) is powered off, the magnet slider (97) is restored to the initial position under the action of the spring mechanism (98), and the rotating shaft (90) is restored to the initial position through the meshing gear (10) thereon under the action of the meshing gear row (951), and the corresponding arc-shaped electromagnetic assembly (11) is also powered off, and under the action of the spring body (122), the moving sleeve (12) drives the supporting shaft (94) and the mechanical components thereon to return to the initial position, and then repeats the S1 operation; S3. When the clamping plate frame A (81) and the clamping plate frame B (82) need to be repositioned, the plate-shaped electromagnetic mechanism (904) is energized to generate an attractive force on the clamping plate frame A (81) and the clamping plate frame B (82), so that the clamping plate frame A (81) and the clamping plate frame B (82) move to the closest position. At this time, the circular magnetic blocks (88) on the telescopic shafts (84) of the two will move to the force-applying magnetic blocks (909) and the lateral area (906), and the force-applying magnetic blocks (909) will generate an attractive force on them, that is, the telescopic shaft (84) in the compressed state is subjected to the force and enters the reciprocating area ( 907), the reset spring (85) is in a stretched state. At this time, the guide plate frame (86) is not on the movement trajectory of the telescopic shaft (84). Then, under the action of the constant force spring (87), the telescopic shaft (84) performs a return movement in the reciprocating area (907) and leaves the force-applying magnetic block (909). When it moves to the intersection of the reciprocating area (907) and the disconnection area (908), the telescopic shaft (84) returns to its initial position along the inclined surface of the disconnection area (908) under the action of the reset spring (85). At this time, the clamping plate frame A (81) and the clamping plate frame B (82) return to their initial positions.
