Description

Technical Field

[0001] The invention relates to the field of mattress production equipment, and in particular to a mattress turning device and a control method thereof. Background Art

[0002] A mattress is an item that is placed between the human body and the bed to ensure that consumers get a healthy and comfortable sleep. Mattresses are made of a variety of materials, and mattresses made of different materials can bring different sleeping effects to people.

[0003] The prior art discloses some invention patents for mattress processing. The Chinese patent with application number 202311775063.X discloses a flipping and fixing device for mattress production, including a base plate, a driving structure is arranged at the front part of the inner cavity of the base plate, a guide frame is symmetrically fixedly connected to the upper end of the base plate, and a plurality of fixed structures rotatably connected to each other are arranged at the ends of the two guide frames close to each other, and the ends of the fixed structures located at the front and rear parts far away from each other are rotatably connected to the guide structure, and the inner cavities of the two guide frames are provided with flipping traction structures.

[0004] In the prior art, during the mattress manufacturing process, after completing the processing of one side of the mattress, the next necessary step is to perform the same processing on the other side of the mattress. However, when the mattress is flipped to a vertical state, some of the fillings may naturally fall down under the action of gravity, which may cause uneven distribution of the fillings inside the mattress, affecting the flatness and support of the mattress. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a mattress turning device and a control method thereof.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a mattress turning device, comprising a base frame, a conveyor fixedly mounted on the base frame, the conveyor being used to convey the mattress to be processed, and further comprising:

[0007] Two groups of slides, each group has two slides, the two groups of slides are symmetrically fixedly connected to the top of the base frame, and the two groups of slides are located on both sides of the conveyor;

[0008] Two groups of grabbing and rotating units are respectively arranged on the two groups of slides;

[0009] Two sets of pushing units, used to push the grabbing and rotating units at corresponding positions to move;

[0010] A detection unit, used for obtaining pressure information;

[0011] A controller is fixedly mounted on the side wall of the conveyor. After the detection unit obtains the pressure information, the controller first controls the pushing unit to vertically lift the corresponding grabbing and rotating unit to a set height, and then controls the grabbing and rotating unit to rotate a preset angle, so that the internal filling of the mattress can be evenly redistributed during the mattress flipping process;

[0012] Among them, the mattress is guided to rotate at a specific angle by the grabbing and rotating unit, so that the flipping angle of the mattress to be processed exceeds one hundred and eighty degrees and is less than two hundred and seventy degrees, and finally the mattress to be processed is in a tilted state. Through the clever use of this tilting posture, it helps to effectively counteract the influence of gravity on the distribution of filling materials, and prompts the filling materials that originally fell and gathered due to gravity to be redistributed to fill the original vacant areas, thereby helping to improve the uniformity of the filling materials inside the mattress and ensure the comfort and overall performance of the mattress. After the mattress to be processed is deflected for a certain period of time, the grabbing and rotating unit drives the mattress to be processed to rotate to a horizontal state, and then the pushing unit drives the grabbing and rotating unit to descend, so that the mattress to be processed after the flipping is completed is transported to the conveyor to facilitate the next processing.

[0013] Preferably: the grabbing and rotating unit comprises:

[0014] A slide plate is slidably connected between two slide frames in the same group, and the pushing unit is used to push the slide plate to move;

[0015] A motor, wherein the motor is fixedly mounted on a side wall of the slide;

[0016] A pusher, fixedly connected to the output shaft end of the motor;

[0017] The clamping plate is fixedly mounted on the end of the pushing member.

[0018] Preferably, it also includes two sets of locking mechanisms, which are respectively arranged on the clamping plates of the grabbing and rotating units at corresponding positions, and the locking mechanisms include:

[0019] A slot, the slot being formed on a side of the clamping plate close to the conveyor;

[0020] A deviation-correcting roller, rotatably connected to the inner wall of the slot;

[0021] Two sliding columns are respectively fixedly connected to the two ends of the rotating shaft of the deviation correction roller;

[0022] Two rotating caps are respectively fixedly connected to ends of the two sliding posts that are away from each other;

[0023] Two rectangular plates are slidably connected to the outer walls of the two sliding columns respectively;

[0024] Two first springs are respectively fixedly connected between the rectangular plate and the clamping plate at corresponding positions, and all the first springs are respectively sleeved on the outer wall of the sliding column at corresponding positions;

[0025] A first locking member, wherein the first locking member is fixedly connected to the rectangular plate located above;

[0026] A second locking member, the second locking member being slidably connected to the rectangular plate located below;

[0027] A second spring, fixedly connected between the rectangular plate and the second locking member;

[0028] The clamping assembly is arranged between the second locking member and the clamping plate.

[0029] Preferably, the engaging assembly comprises:

[0030] A first electric push rod is fixedly mounted on the bottom of the clamping plate;

[0031] A locking groove is formed on a side wall of the second locking member;

[0032] The clamping plate is fixedly connected to the telescopic end of the first electric push rod.

[0033] Preferably, it also includes:

[0034] A plurality of exhaust fans are fixedly mounted on the side walls of the clamping plate;

[0035] A plurality of suction ports are provided on the side wall of the clamping plate;

[0036] An air duct, fixedly installed between the air inlet of the exhaust fan and the suction port;

[0037] The present invention adsorbs the inner depression that may be generated in the mattress to be processed during the process of the adsorption ports on the two clamping plates moving away from each other. At this time, the negative pressure of the adsorption port can play a corrective function, which can instantly repair the local depression that may be generated when the mattress is squeezed by the clamping plates, and restore the surface of the mattress to a flat state through the adsorption force, thereby providing a good foundation for subsequent processing steps and ensuring the processing accuracy and the final quality of the mattress. After the mattress moves below the conveying surface of the conveyor and drops to a specified height, the pressure information obtained by the pressure sensor disappears, and then the controller controls the exhaust fan to stop working. As the mattress continues to drop, it helps to move the mattress to be processed to the conveyor for transportation, thereby helping to transport the mattress after the adsorption of the mattress is released, and helping to avoid interference with the transportation of the mattress caused by adsorption.

[0038] Preferably, it also includes:

[0039] A plurality of conveying rollers are rotatably connected to the second locking member in a linear array, and the length of the conveying rollers is greater than the width of the second locking member.

[0040] Preferably, the detection unit comprises two groups of pressure sensors, and the two groups of pressure sensors are respectively fixedly installed on opposite sides of the two clamping plates.

[0041] In a second aspect, the present invention provides a control method for a mattress turning device, the control method comprising the following steps:

[0042] The controller receives pressure information obtained by the pressure sensor;

[0043] The controller generates first control information according to the pressure information;

[0044] The controller sends the first control information to the pushing unit to control the pushing unit to start pushing out, so that the pushing unit drives the mattress to be processed to be lifted upward through the clamping plate;

[0045] The controller receives the work completion information of the pushing unit;

[0046] The controller generates second control information according to the work completion information of the pushing unit;

[0047] The controller sends the second control information to the motor to control the motor to drive the clamping plate to deflect a specified angle through the pushing member;

[0048] Among them, after the pressure sensor contacts the side wall of the mattress, the pressure sensor will collect pressure data when it detects pressure changes. The pressure reading recorded at this moment is called pressure information. Subsequently, the pressure sensor feeds back the pressure information to the controller, and the controller generates first control information based on the pressure information.

[0049] Preferably, it also includes:

[0050] The controller generates third control information when the pushing unit starts pushing out;

[0051] The controller sends the third control information to the exhaust fan to control the exhaust fan to start, so that a negative pressure space is formed near the adsorption port.

[0052] Preferably, it also includes:

[0053] The controller obtains the level information;

[0054] The controller generates fourth control information according to the level information;

[0055] The controller sends fourth control information to the first electric push rod to control the first electric push rod to drive the clamping plate to slide out from the inside of the clamping slot;

[0056] Among them, after the controller controls the motor to drive the clamping plate to deflect to the tilted state and maintain it for a certain period of time, the controller will control the motor to drive the clamping plate to deflect to the initial state again, which is defined as "horizontal information";

[0057] The initial state refers to the state when the motor drives the clamping plate to drive the mattress to be processed to a flip angle exceeding 180 degrees and less than 270 degrees, and then drives the mattress to be processed to deflect to a state parallel to the ground. This is called the "initial state".

[0058] Compared with the prior art, the present invention has the following beneficial effects:

[0059] 1. The present invention sets a grabbing and rotating unit to guide the mattress to rotate at a specific angle, so that the flipping angle of the mattress to be processed exceeds one hundred and eighty degrees and is less than two hundred and seventy degrees, and finally the mattress to be processed is in an inclined state. Through the clever use of this inclined posture, it is helpful to effectively counteract the influence of gravity on the distribution of the filling material, and the filling material that originally fell and gathered due to gravity is redistributed to fill the original vacant area, thereby helping to improve the uniformity of the filling material inside the mattress and ensure the comfort and overall performance of the mattress. After the mattress to be processed deflects for a certain period of time, the grabbing and rotating unit drives the mattress to be processed to rotate to a horizontal state, and then the pushing unit drives the grabbing and rotating unit to descend, so that the mattress to be processed after flipping is transported to the conveyor to facilitate the next step of processing.

[0060] 2. The present invention helps to position and fix the mattress to be processed through the arrangement of the first locking member and the second locking member, and the synergistic effect of the first locking member and the second locking member, so as to avoid accidental slipping during the processing, which is beneficial to ensure the stability and safety of the processing. Secondly, this design can respond quickly when the mattress shows signs of slipping, and activate the locking mechanism in time to prevent the mattress from further falling off, which helps to avoid possible production accidents and product damage. Finally, this locking mechanism will only be activated when there is a risk of the mattress falling off, thereby helping to avoid the first locking member and the second locking member from contacting the mattress when it is unnecessary, reducing friction and possible damage to the mattress surface, and ensuring the integrity of the mattress, thereby improving product quality.

[0061] 3. The present invention provides the adsorption port. On the one hand, the adsorption force generated by the negative pressure can firmly adsorb the mattress, effectively preventing it from being displaced or falling off due to external force or vibration during processing, which is beneficial to ensure the safety and stability of the flipping process. On the other hand, the adsorption ports on the two clamping plates can adsorb the inner depression that may be generated in the mattress to be processed when they move away from each other, which is beneficial to the immediate repair of the local depression that may be generated when the mattress is squeezed by the clamping plates, and the surface of the mattress is restored to a flat state through the adsorption force.

DETAILED DESCRIPTION

[0075] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0076] Application scenario: In the prior art, in the mattress manufacturing process, after completing the processing of one side of the mattress, the next necessary step is to perform the same processing on the other side of the mattress. However, when the mattress is flipped to a vertical state, some of the fillings may naturally fall under the action of gravity, which may cause the fillings inside the mattress to be unevenly distributed, and the other side appears empty, affecting the flatness and support of the mattress.

[0077] like Figures 2 to 12 The mattress turning device shown in the figure comprises a base frame 1, on which a conveyor is fixedly mounted, the conveyor being used to convey the mattress to be processed, and further comprises:

[0078] Two groups of slides 3, each group has two slides, the two groups of slides 3 are symmetrically fixedly connected to the top of the base frame 1, and the two groups of slides 3 are located on both sides of the conveyor;

[0079] Two groups of grabbing and rotating units are respectively arranged on two groups of slides 3;

[0080] Two sets of pushing units are used to push the grabbing and rotating units at corresponding positions to move;

[0081] A detection unit, used for obtaining pressure information;

[0082] The controller 4 is fixedly mounted on the side wall of the conveyor. After the detection unit obtains the pressure information, the controller 4 first controls the pushing unit to vertically lift the corresponding grabbing and rotating unit to a set height, and then controls the grabbing and rotating unit to rotate a preset angle, so that the internal filling of the mattress can be evenly redistributed during the mattress flipping process;

[0083] It should be understood that the mattress to be processed is transported between the two groups of grabbing and rotating units, and then the grabbing and rotating units clamp and limit the mattress. At this time, the detection unit will obtain pressure information, and the controller 4 will control the pushing unit to start working, and the two groups of grabbing and rotating units will be synchronously pushed to move vertically upward by the pushing unit. Because the mattress is clamped and limited by the grabbing and rotating units at this time, the mattress will move upward with the grabbing and rotating units. After the pushing unit lifts the grabbing and rotating units to a predetermined height, the controller 4 will start immediately to accurately control the rotation action of the grabbing and rotating units. Considering that under the action of gravity, the internal fillings tend to fall to the bottom when the mattress is turned over, which is easy to form local accumulation and affect the uniform distribution of the fillings. Therefore, the bed is guided by the grabbing and rotating units. The pad is rotated at a specific angle, so that the flipping angle of the mattress to be processed exceeds one hundred and eighty degrees and is less than two hundred and seventy degrees, and finally the mattress to be processed is tilted. Through the clever use of this tilting posture, it helps to effectively counteract the influence of gravity on the distribution of filling materials, and prompts the filling materials that originally fell and gathered due to gravity to be redistributed to fill the original vacant areas, thereby helping to improve the uniformity of the filling materials inside the mattress and ensure the comfort and overall performance of the mattress. After the mattress to be processed is deflected for a certain period of time, the grabbing and rotating unit drives the mattress to be processed to rotate to a horizontal state, and then the pushing unit drives the grabbing and rotating unit to descend, so that the mattress to be processed after the flipping is completed is transported to the conveyor to facilitate the next processing.

[0084] It should be noted that the conveyor is composed of existing components such as the conveyor belt 2, the side plate 20, the drive motor 21, etc. It is an existing mature technology and is used in various industries, so it will not be elaborated here.

[0085] As a technical optimization solution of the present invention: the grabbing and rotating unit includes:

[0086] The slide plate 7 is slidably connected between the two slide frames 3 in the same group, and the pushing unit is used to push the slide plate 7 to move;

[0087] The motor 8 is fixedly mounted on the side wall of the slide plate 7;

[0088] A pusher 9 is fixedly connected to the output shaft end of the motor 8;

[0089] A clamping plate 10 is fixedly mounted on the end of the pusher 9;

[0090] It should be understood that the controller 4 controls the push member 9 to start, and the push member 9 pushes the clamping plate 10 to clamp the mattress to be processed, and enables the detection unit to obtain pressure information. After the mattress to be processed is transported to the specified position, the controller 4 controls the motor 8 to start, and the motor 8 drives the push member 9 to rotate, and the push member 9 drives the clamping plate 10 to rotate, thereby driving the mattress to be processed to deflect by a specified angle, thereby helping to offset the adverse effects of gravity on the distribution of filling materials during the flipping process of the mattress to be processed, and by causing the filling materials that originally tended to concentrate at the bottom and formed accumulations due to gravity to flow and redistribute again, it helps to backfill the vacant parts inside the mattress, thereby helping to improve the overall uniformity of the mattress filling distribution.

[0091] It should be noted that the pusher 9 can be a second electric push rod or a cylinder.

[0092] It needs to be explained again that the pushing unit includes a hydraulic push rod 5, which is fixedly connected to the inside of a groove opened on the base frame 1, and the telescopic end of the hydraulic push rod 5 is fixedly connected to a connecting plate 6, and the connecting plate 6 is fixedly connected to the slide plate 7.

[0093] As a technical optimization solution of the present invention: it also includes two sets of locking mechanisms, which are respectively arranged on the clamping plates 10 of the grabbing and rotating units at corresponding positions, and the locking mechanisms include:

[0094] A slot 11, which is provided on a side of the clamping plate 10 close to the conveyor;

[0095] A deviation-correcting roller 12 is rotatably connected to the inner wall of the slot 11;

[0096] Two slide posts 13 are respectively fixedly connected to two ends of the rotating shaft of the deviation correction roller 12;

[0097] Two rotating caps 14 are respectively fixedly connected to ends of the two sliding posts 13 that are away from each other;

[0098] Two rectangular plates 15 are slidably connected to the outer walls of the two sliding posts 13 respectively;

[0099] Two first springs 16 are respectively fixedly connected between the rectangular plate 15 and the clamping plate 10 at corresponding positions, and all the first springs 16 are respectively sleeved on the outer wall of the sliding column 13 at corresponding positions;

[0100] A first locking member 17, the first locking member 17 is fixedly connected to the rectangular plate 15 located above;

[0101] A second locking member 18, the second locking member 18 is slidably connected to the rectangular plate 15 located below;

[0102] A second spring 19, fixedly connected between the rectangular plate 15 and the second locking member 18;

[0103] A clamping assembly, disposed between the second locking member 18 and the clamping plate 10;

[0104] It should be understood that in the above example, the mattress to be processed is turned over by the clamping plate 10 at a specified angle so that the filling inside the mattress to be processed is evenly distributed. However, after the mattress to be processed is tilted, the mattress may slip, thereby causing unnecessary damage.

[0105] Therefore, when the clamping plate 10 is fixing the mattress to be processed, the correcting roller 12 will also come into contact with the mattress to be processed. If the mattress slips during the flipping or tilting process, the correcting roller 12 will rotate under the action of the mattress to be processed, and the rotation of the correcting roller 12 will drive the sliding column 13 to rotate, and the sliding column 13 will drive the rotating cap 14 to rotate. The rotating cap 14 has a certain inclined surface, so the rotating cap 14 pushes the rectangular plate 15 to slide on the outer wall of the sliding column 13 during the rotation process, so that the rectangular plate 15 drives the first locking piece 17 and the second locking piece 18 to press and lock the outer side of the mattress to be processed. The synergistic effect of 8 helps to position and fix the mattress to be processed, avoiding it from accidentally slipping off during processing, which is beneficial to ensure the stability and safety of the processing. Secondly, this design can respond quickly when the mattress shows signs of slipping, and activate the locking mechanism in time to prevent the mattress from further falling off, which helps to avoid possible production accidents and product damage. Finally, this locking mechanism will only be activated when the mattress is at risk of falling off, thereby preventing the first locking member 17 and the second locking member 18 from contacting the mattress when it is not necessary, reducing friction and possible damage to the mattress surface, ensuring the integrity of the mattress, and improving product quality.

[0106] It should be specially noted that the two first locking members 17 are respectively arranged on both sides of the conveyor and correspond to each other on the left and right sides, and the distance between the two first locking members 17 is greater than the width of the conveyor.

[0107] As a technical optimization solution of the present invention: the engaging assembly includes:

[0108] The first electric push rod 22 is fixedly mounted on the bottom of the clamping plate 10;

[0109] The engaging groove 23 is formed on the side wall of the second locking member 18;

[0110] The clamping plate 24 is fixedly connected to the telescopic end of the first electric push rod 22;

[0111] It should be understood that after the mattress is flipped, it is necessary to place the mattress on the conveyor for transportation. Therefore, after the mattress is flipped to the ideal state, the controller 4 controls the first electric push rod 22 to start working. The first electric push rod 22 drives the locking plate 24 to move, so that the locking plate 24 slides out from the inside of the locking groove 23, thereby causing the second locking piece 18 to lose its limit. At this time, the mattress to be processed will compress the second locking piece 18 and move in the direction of the conveyor. The second locking piece 18 will move down to below the conveying plane of the conveyor under the action of the gravity of the mattress to be processed, thereby helping to better transport the mattress to be processed to the conveyor. In this process, the second spring 19 can effectively buffer the speed of the mattress during the descent process. Through progressive energy absorption, the impact force of the mattress falling is greatly reduced, so that the mattress to be processed contacts the conveyor in a relatively gentle manner, which helps to reduce the risk of damage to the mattress's own structure or damage to the conveyor below due to sudden high-speed impact, thereby protecting the integrity of the mattress and the safe operation of the conveying system.

[0112] As a technical optimization solution of the present invention: it also includes:

[0113] A plurality of exhaust fans 25 are fixedly mounted on the side walls of the clamping plate 10;

[0114] A plurality of suction ports 26 are provided on the side wall of the clamping plate 10;

[0115] The air duct 27 is fixedly installed between the air inlet of the exhaust fan 25 and the suction port 26;

[0116] It should be understood that when the pushing unit drives the mattress to be processed to move upward through the clamping plate 10, the controller 4 synchronously controls the exhaust fan 25 to start working, thereby forming a negative pressure space near the suction port 26. On the one hand, the suction force generated by the negative pressure can firmly adsorb the mattress, effectively preventing it from being displaced or falling off due to external force or vibration during processing, which is conducive to ensuring the safety and stability of the turning process;

[0117] Before the engaging plate 24 slides out from the engaging groove 23, the controller 4 first controls the pusher 9 to drive the clamping plate 10 to return to the specified distance. At this time, the exhaust fan 25 continues to work, so that the suction ports 26 on the two clamping plates 10 can absorb the inner depression that may be generated in the mattress to be processed during the process of moving away from each other. At this time, the negative pressure of the suction port 26 can play a corrective function, which can instantly repair the local depression that may be generated when the mattress is squeezed by the clamping plate 10, and restore the mattress surface to a flat state through the suction force, which provides a good foundation for subsequent processing steps and ensures the processing accuracy and the final quality of the mattress;

[0118] During the process of the locking plate 24 sliding out from the locking groove 23, the controller 4 controls the exhaust fan 25 to stop working. After the locking plate 24 slides out from the locking groove 23, the second locking piece 18 moves downward under the action of the gravity of the mattress to be processed. As the mattress continues to descend, it helps to move the mattress to be processed to the conveyor for transportation, thereby helping to transport the mattress after the adsorption of the mattress is released, and helping to avoid the interference of the transportation of the mattress due to adsorption.

[0119] As a technical optimization solution of the present invention: it also includes:

[0120] A plurality of conveying rollers 28 are rotatably connected to the second locking member 18 in a linear array, and the length of the conveying rollers 28 is greater than the width of the second locking member 18;

[0121] It should be understood that after the mattress to be processed contacts the conveyor, the conveyor drives the mattress to be processed to move, and at this time, the conveying roller 28 converts the sliding friction into rolling friction, thereby facilitating the conveying of the mattress to be processed;

[0122] In addition, the length of the conveying roller 28 is longer than the width of the second locking member 18. Therefore, when the pushing member 9 drives the clamping plate 10 to move, the conveying roller 28 will continue to provide support for the mattress to be processed after the suction port 26 is away from the mattress to be processed, thereby helping to prevent the mattress to be processed from suddenly falling off.

[0123] As a technical optimization solution of the present invention: the detection unit includes two groups of pressure sensors 29, and the two groups of pressure sensors 29 are fixedly installed on opposite sides of the two clamping plates 10;

[0124] It should be understood that after the pressure sensor 29 contacts the mattress, pressure information is acquired, and the information is fed back to the controller 4 for processing.

[0125] like Figure 1 A control method for a mattress turning device is shown, the control method comprising the following steps:

[0126] The controller 4 receives the pressure information obtained by the pressure sensor 29;

[0127] The controller 4 generates first control information according to the pressure information;

[0128] The controller 4 sends the first control information to the pushing unit to control the pushing unit to start pushing out, so that the pushing unit drives the mattress to be processed to be lifted upward through the clamping plate 10;

[0129] The controller 4 receives the information that the pushing unit has completed its work;

[0130] The controller 4 generates second control information according to the work completion information of the pushing unit;

[0131] The controller 4 sends the second control information to the motor 8 to control the motor 8 to drive the clamping plate 10 to deflect a specified angle through the pusher 9;

[0132] It should be noted that after the pressure sensor 29 obtains the pressure information, it is assumed that the clamping plate 10 has completed the clamping of the mattress to be processed, and the pushing unit drives the mattress to be processed upward to a specified distance through the clamping plate 10. After the pushing unit drives the mattress to be processed upward to a specified distance through the clamping plate 10, it is called "pushing unit work completion information".

[0133] As a technical optimization solution of the present invention: it also includes:

[0134] The controller 4 generates third control information during the process of the pushing unit starting to push out;

[0135] The controller 4 sends the third control information to the exhaust fan 25 to control the exhaust fan 25 to start, so that a negative pressure space is formed near the suction port 26;

[0136] It should be noted that, when the pushing unit drives the mattress to be processed to move upward through the clamping plate 10 , the controller 4 will generate third control information for controlling the exhaust fan 25 to start.

[0137] As a technical optimization solution of the present invention: it also includes:

[0138] The controller 4 obtains the horizontal information;

[0139] The controller 4 generates fourth control information according to the level information;

[0140] The controller 4 sends the fourth control information to the first electric push rod 22 to control the first electric push rod 22 to drive the engaging plate 24 to slide out from the engaging slot 23 .

[0141] Working principle of the present invention:

[0142] The mattress to be processed is transported between the two groups of grabbing and rotating units, and then the grabbing and rotating units clamp and limit the mattress. At this time, the detection unit will obtain the pressure information, and the controller 4 will control the pushing unit to start working, and the two groups of grabbing and rotating units will be synchronously pushed to move vertically upward by the pushing unit. Because the mattress is clamped and limited by the grabbing and rotating units at this time, the mattress will move upward with the grabbing and rotating units. After the pushing unit lifts the grabbing and rotating units to a predetermined height, the controller 4 will start immediately to accurately control the rotation action of the grabbing and rotating units. Considering that under the action of gravity, the internal fillings tend to fall to the bottom when the mattress is turned over, which is easy to form local accumulation and affect the uniform distribution of the fillings. Therefore, the mattress is guided in through the grabbing and rotating units. The mattress to be processed is rotated at a specific angle so that the flipping angle of the mattress to be processed exceeds one hundred and eighty degrees and is less than two hundred and seventy degrees, and finally the mattress to be processed is tilted. Through the clever use of this tilting posture, it is helpful to effectively counteract the influence of gravity on the distribution of filling materials, and prompt the filling materials that originally fell and gathered due to gravity to be redistributed to fill the original vacant areas, thereby helping to improve the uniformity of the filling materials inside the mattress and ensure the comfort and overall performance of the mattress. After the mattress to be processed is deflected for a certain period of time, the grabbing and rotating unit drives the mattress to be processed to rotate to a horizontal state, and then the pushing unit drives the grabbing and rotating unit to descend, so that the mattress to be processed after the flipping is completed is transported to the conveyor to facilitate the next processing.
