[0003] At present, most of the clothes in the family are manually folded and dried, and the clothes are folded and stored by manual folding or folding board assisted folding, which is time-consuming and laborious. With the increase of the types of clothes, folding clothes is more complicated, and many people do not know how to fold clothes, which greatly affects people's life experience. The new generation of consumers are willing to accept intelligent experience and are willing to pay for their preferences, but they do not want to waste valuable time on tedious things. The clothes folding machine is a product derived from the upgrading of the new generation of consumer demand for clothes folding experience, which helps people to realize automatic folding of clothes and can effectively liberate people from tedious housework.

[0004] The conveying device of the clothes folding machine is composed of a rubber roller, a conveying belt, a motor, a fixed seat and the like.

[0058] As shown, Figures 1-7As shown, in order to make the clothes of the first conveying path smoothly enter the second conveying path, both sides of the conveying device 100 are provided with folding flaps 121 which can be folded to the surface of the conveying device 100, and the part of the clothes to be folded which exceeds the width of the conveying device 100 is folded to make the width of the clothes uniform, which is beneficial to subsequent conveying and folding. The folding flaps 121 are foldably mounted on the rack by a folding mechanism.

[0059] The folding mechanism comprises a fixed support 130 fixedly connected with the rack, and a first folding plate 131 and a second folding plate 132. The folding flaps 121 are fixedly connected with the second folding plate 132 and can be folded synchronously with the second folding plate 132. The right end of the first folding plate 131 is hingedly connected with the upper end of the fixed support 130, and the left end is hingedly connected with the right end of the second folding plate 132. The folding mechanism further comprises a first connecting rod 133 and a second connecting rod 134. The first connecting rod 133 and the second connecting rod 134 are arranged on the front and rear sides of the fixed support 130. The left end of the first connecting rod 133 is hingedly connected with the left end of the second folding plate 132, the right end of the second connecting rod 134 is hingedly connected with the lower end of the fixed support 130, and the left end of the second connecting rod 134 is hingedly connected with the left end of the first connecting rod 133. The folding mechanism further comprises a push rod 135, the upper end of the push rod 135 is hingedly connected with the second connecting rod 134, and the lower end of the push rod 135 is connected with a folding plate driving device 136. The push rod 135 can reciprocate along its axis direction under the driving of the folding plate driving device 136, thereby driving the hinge points of the first connecting rod 133 and the second connecting rod 134 to reciprocate between the side and the back side of the clothes folding platform where the clothes to be folded are placed, and driving the first folding plate 131 and the second folding plate 132 to fold.

[0060] As a preferred embodiment of the present application, a fixed seat 139 is fixedly connected with the rack, and the folding plate driving device 136 is rotatably mounted on the fixed seat 139, so that the upper end of the push rod 135 can rotate around the fixed seat 139 to approach or move away from the clothes folding platform. Preferably, the folding plate driving device 136 drives the push rod 135 to reciprocate through screw transmission. More preferably, the folding plate driving device 136 and the push rod 135 are integrally arranged as an electric cylinder.

[0061] When the folding flap 121 is in the unfolded state, the flap driving device 136 drives the push rod 135 to push the first connecting rod 133 and the second connecting rod 134 upwards, thereby pushing the second folding flap 132 to fold towards the clothes folding platform. An elastic member is arranged between the first folding flap 131 and the second folding flap 132, which provides an elastic force to keep the first folding flap 131 and the second folding flap 132 flat. Under the action of the elastic force, the first folding flap 131 can be folded synchronously with the second folding flap 132. A limiting portion 137 is arranged on the fixed support 130. When the first folding flap 131 is folded to a certain angle, the limiting portion 137 stops the first folding flap 131, thereby limiting the further folding of the first folding flap 131. Preferably, the limiting portion 137 is a vertical plane arranged on the fixed support 130. When the first folding flap 131 is folded by 90°, the first folding flap 131 stops folding by abutting against the limiting portion 137. The flap driving device 136 continues to drive the push rod 135 to move upwards, and the second folding flap 132 continues to fold against the elastic force of the elastic member until it is folded above the clothes folding platform. Due to the presence of the first folding flap 131, the folding flap 121 has a certain distance from the surface of the clothes folding platform after being folded, thereby reserving space for the folded clothes.

[0062] When the folding flap 121 is unfolded from the folded state, the flap driving device 136 drives the push rod 135 to pull the first connecting rod 133 and the second connecting rod 134 downwards, thereby driving the second folding flap 132 to fold away from the clothes folding platform. The first folding flap 131 has a fixed stop portion 138. When the second folding flap 132 is folded to be flat with the first folding flap 131, the second folding flap 132 stops against the stop portion 138. The flap driving device 136 continues to drive the push rod 135 to move downwards, and the second folding flap 132 pushes the stop portion 138, thereby driving the first folding flap 131 to fold synchronously until it is flat with the clothes folding platform.

[0063] In the above technical solution of the embodiment, the first folding flap and the second folding flap form a folding mechanism. The first folding flap stops folding after being folded by a certain angle, and the second folding flap drives the folding flap to continue folding, so that the folding flap has a certain distance from the surface of the clothes folding platform when it is folded above the clothes folding platform, thereby reserving space for the folded clothes. This avoids the situation that the folding flap cannot be folded by 180° when the clothes are thick. The part of the folding flap away from the folding shaft can also compact the clothes, thereby achieving good forming effect of the folded clothes.

[0075] In order to enable the clothes to smoothly enter the folding conveying path, the clothes folding machine is further provided with a movable folding pressing mechanism which can press the clothes into the conveying path.

[0076] The folding pressing mechanism comprises a first folding pressing mechanism 501 which can press the clothes at the entrance of the seventh conveying path to form the crease required when the clothes are folded for the first time, and can press the clothes to be folded into the seventh conveying path, so as to prevent the clothes from not traveling along the predetermined route and prevent the clothes from being unable to form the folded state. Preferably, the first folding pressing mechanism 501 can be provided as a retractable pressing plate, when the clothes need to pass through, the pressing plate is in the retracted state and does not affect the conveying of the clothes, when the clothes reach the specified position, the pressing plate is pressed to form the crease of the clothes, and the clothes enter the next conveying path from the crease position.

[0077] The folding pressing mechanism further comprises a second folding pressing mechanism 502 which has the same function as the first folding pressing mechanism 501, can form the crease of the clothes by retracting, and can press the clothes into the eighth conveying path along the position of the crease, so that the clothes are conveyed along the predetermined route.

[0078] As Figure 1 and 8 - Figure 10As shown, as a preferred embodiment of the present application, the clothes entry of the folding machine, i.e. the right end of the conveying device 100 is provided with a clothes entry guide plate 20, and the two sides of the clothes entry guide plate 20 are provided with horn-shaped guide portions 21, forming two grooves. Before the clothes enter the clothes entry and are unfolded on the folding platform formed by the conveying device 100, the clothes first pass through the clothes entry guide plate 20, and the two sides of the guide portions 21 can perform the first folding in the width direction of the clothes. Especially for shirts, when passing through the clothes entry guide plate 20, the sleeve part is guided into the two sides of the grooves under the guide of the guide portions 21, and is folded to the lower side of the main body of the clothes during the loading of the clothes, and the folding of the sleeves is completed before the clothes reach the folding platform, so that the width of the clothes is more uniform, which is beneficial to the subsequent folding steps.

[0079] The clothes entry guide plate 20 is rotatably installed at the corresponding position of the clothes entry on the frame. The frame is fixedly connected with a guide plate support 23, and the guide plate support 23 is provided with a mounting hole. The clothes entry guide plate is provided with a rotating shaft 22, which is rotatably inserted into the mounting hole. The clothes entry guide plate 20 and the guide plate support 23 are in clearance fit and can rotate around the rotating shaft 22. When the folding machine is working, the clothes entry guide plate 20 is in an unfolded state and extends out of the clothes entry and is flush with the surface of the conveying device 100. When the folding machine is not working, the user can manually operate to fold the clothes entry guide plate 20 towards the clothes entry, so that it is folded to the inside of the clothes entry and is in a storage state. Preferably, the clothes entry guide plate 20 can be folded to contact the surface of the conveying device 100.

[0080] As a preferred embodiment of the present application, the folding machine is provided with a driving device connected with the rotating shaft 22, which can drive the rotating shaft to rotate, thereby driving the clothes entry guide plate 20 to rotate on the frame, and the automatic switching of the clothes entry guide plate 20 between the unfolded state and the storage state can be realized.

[0081] In this embodiment, the folding machine is provided with a clothes entry guide plate extending out of the clothes entry, which can arrange the width of the clothes before the clothes enter the clothes entry. The clothes entry guide plate is rotatably installed on the frame and can be folded to the inside of the clothes entry when the folding machine is not working, thereby saving the space occupied by the folding machine when it is stored, facilitating packaging, and reducing the probability of damage to the clothes entry guide plate during transportation.

[0082] As a preferred embodiment of the present application, the folding machine can obtain the length range of the clothes during the conveying of the clothes, judge whether it is less than a preset length L', and according to the different judgment results, the conveying mode of the folding conveying device 300 is different, and the moving mode of the first folding mechanism 501 and the second folding mechanism 502 is also different.

[0083] As shown in FIG. 7, the folding machine is provided with a length sensor 200, which is arranged on the frame and is arranged on the conveying device 100. The length sensor 200 is arranged on the frame and is arranged on the conveying device 100. Figures 1-11The first and second sensing units are arranged on the conveying device to detect the length of the clothes to be folded, and the main control system controls the folding action of the clothes to be folded on the conveying device according to the length of the clothes to be folded, so that a better folding effect is achieved.

[0084] Specifically, the conveying device has a conveying path with a conveying path entry end and a conveying path terminal end, and the clothes move from the conveying path entry end to the conveying path terminal end. The first and second sensing units are arranged on the conveying path, and the second sensing unit is a certain distance L' away from the first sensing unit. Preferably, L' = 62 cm.

[0085] The conveying path entry end and the conveying path terminal end do not refer to the entry end and the terminal end of the clothes to be folded, but only to the arrangement position of the first and second sensing units for clear description.

[0086] Preferably, the first and second sensing units are photoelectric sensors connected to the main control system. More preferably, the photoelectric sensor is a reflection type photoelectric sensor, which uses reflection photoelectric sensing technology to detect the clothes, and is beneficial to improve the ability of the clothes folding machine to measure the length of clothes of different colors and materials.

[0087] The method for obtaining the length range of the clothes includes: moving the clothes along the clothes entering direction; when the second sensing unit senses the clothes, the main control system determines whether the first sensing unit senses the clothes; when the first sensing unit senses the clothes, it is determined that the length L of the clothes is greater than L'; and when the first sensing unit does not sense the clothes, it is determined that the length L of the clothes is less than L'.

[0088] In the above clothes length detection method, the reflection type photoelectric sensor is composed of two parts, a light emitter and a light receiver. When there is no obstacle between the two, the light emitter of the sensor emits light, and the light receiver receives the light. At this time, the light receiver outputs a low-level signal. Conversely, when there is an obstacle between the light emitter and the light receiver, the light receiver outputs a high-level signal.

[0089] The first sensing unit 701 and the second sensing unit 702 cooperate to detect the length range of the clothes. The transmission distance L' between the first sensing unit and the second sensing unit is fixedly set, for example, can be 62 cm. If the second sensing unit is true (detects clothes), the first sensing unit is still true (detects clothes), at this time, it is judged that the length of the clothes is greater than or equal to the transmission distance L' between the first sensing unit and the second sensing unit. If the second sensing unit is true (detects clothes), the first sensing unit is false (does not detect clothes), at this time, it is judged that the length of the clothes is less than the transmission distance L' between the first sensing unit and the second sensing unit.

[0090] For clothes with a length less than L', the clothes are folded once in the folding conveying device, specifically including the following steps:

[0091] 1) The first folding conveying device 301 and the second folding conveying device 302 convey the clothes to the left, so that the clothes are flattened on the surface of the first folding conveying device 301 and the second folding conveying device 302;

[0092] 2) The first folding conveying device 301 conveys to the left, and the second folding conveying device 302 conveys to the right, while the first folding mechanism 501 moves downward to press the clothes into the seventh conveying path, and the clothes are folded once and conveyed downward;

[0093] 3) The first folding mechanism 501 moves upward to withdraw the seventh conveying path, while the second folding conveying device 302 and the third folding conveying device 303 convey towards each other, conveying the clothes to the eighth conveying path, and then conveying out into the storage unit 800.

[0094] For clothes with a length greater than or equal to L', the clothes are folded twice in the folding conveying device, specifically including the following steps:

[0095] 1) The first folding conveying device 301 and the second folding conveying device 302 convey the clothes to the left until the end of the clothes completely enters the first folding conveying device 301;

[0096] 2) The second folding conveying device 302 conveys to the left, and the first folding conveying device 302 conveys to the right, while the first folding mechanism 501 moves downward to insert the seventh conveying path, and the clothes are pressed into the seventh conveying path, and the clothes are folded once and conveyed downward;

[0097] 3) The first folding mechanism 501 moves upward to withdraw the seventh conveying path, while the first folding conveying device 301 and the third folding conveying device 303 convey in the same direction, so that the folded part of the clothes is conveyed to the ninth conveying path;

[0098] 4) The second folding conveyer 302 and the third folding conveyer 302 reverse the direction of conveyance, while the second folding mechanism 502 moves to the left and inserts into the eighth conveyance path, and the clothes are folded into the eighth conveyance path, and the second folding occurs;

[0099] 5) The second folding mechanism 502 moves to the right and withdraws from the eighth conveyance path, while the first folding conveyer 301, the second folding conveyer 302 and the third folding conveyer 303 continue to convey, and the clothes are conveyed out into the storage unit 800.

[0100] In this embodiment, when the clothes are unfolded on the surface of the conveying conveyer, the folding flap of the folding machine is controlled to fold towards the folding platform, and the part of the clothes to be folded which exceeds the width of the conveying conveyer is folded and arranged, so that the width of the clothes is uniform, which is beneficial to the subsequent conveyance and folding. The folding unit is provided with a sensing unit for identifying the length of the clothes to be folded. According to the judgment result of the sensing unit, the folding conveyer, the first folding mechanism and the second folding mechanism are automatically controlled to adopt different action modes to fold the clothes in different ways. The shorter clothes are folded once, and the longer clothes are folded twice, so that the length of the folded clothes is more similar, which is beneficial to the subsequent storage process.

[0101] Figure 11 As shown, the storage unit 800 of the folding machine is provided with a movable storage platform 810. During the output of the clothes from the clothes outlet, the storage platform 810 can move horizontally below the clothes outlet to receive the clothes. The storage unit 800 includes a horizontal moving mechanism that can drive the storage platform 810 to move horizontally, and a vertical moving mechanism that can drive the storage platform 810 to move vertically close to or away from the clothes outlet. The vertical moving mechanism can drive the storage platform 810 to move up and down to adjust the height of the clothes receiving. The storage platform 810 is installed on the horizontal moving mechanism and can reciprocate in the horizontal direction under the driving of the horizontal moving mechanism. The horizontal moving mechanism is installed on the vertical moving mechanism, and the vertical moving mechanism can drive the horizontal moving mechanism and the storage platform 810 to reciprocate up and down as a whole.

[0102] Specifically, the vertical moving mechanism includes two intersecting support rods 811 forming an X-shaped structure, the middle of the support rods 811 is connected by a fixed shaft and can rotate relatively, the vertical moving mechanism includes two groups of symmetrically arranged X-shaped structures, forming a stable and telescopic support structure. One end of the support rod 811 is fixed, and the other end can move reciprocatingly in the horizontal direction, so as to realize the relative rotation between the two support rods 811, and then drive the storage platform 810 to move up and down to adjust the height. The vertical moving mechanism further includes an upper slide rail 815 and a lower slide rail 816, one end of one of the support rods 811 of the X-shaped structure moves along the upper slide rail 815, and the other end of the other support rod moves along the lower slide rail 816. The horizontal moving mechanism and the storage platform 810 are arranged at the top of the support structure, and different heights are formed during the sliding process of the support rods 811. The vertical moving mechanism further includes a first driving motor 814, which drives the support rod 811 to move through a transmission structure. Preferably, the first driving motor 814 drives the support rod 811 to move in a screw drive manner. The transmission structure includes a lead screw 812 and a lead screw nut 813, the lead screw nut 813 is fixedly connected to the movable end of the support rod 811, the lead screw 812 is connected to the first driving motor 814 through a shaft coupling and rotates with the first driving motor 814, the lead screw nut 813 is sleeved on the lead screw 812 and moves horizontally with the rotation of the lead screw 812, thereby driving the support rod 811 to rotate and form different heights.

[0103] The vertical moving mechanism supports the horizontal moving mechanism through four supporting blocks at the top, the horizontal moving mechanism includes a frame 821 supporting the storage platform 810, the frame 821 is provided with two guide rails 822, and four sliding blocks 826 are fixedly connected to the bottom of the storage platform 810 and are installed on the frame 821 and can move reciprocatingly along the guide rails 822. The horizontal moving mechanism further includes a second driving motor 823, which drives the storage platform 810 to move horizontally reciprocatingly through a transmission assembly. The transmission assembly includes a first synchronous belt 824 and a first synchronous pulley 825, the second driving motor 823 is fixedly connected to the first synchronous pulley 825, and the bottom of the storage platform 810 is fixed to the first synchronous belt 824. The second driving motor 823 drives the first synchronous pulley 825 to rotate, and the first synchronous belt 824 sleeved on the first synchronous pulley 825 moves accordingly. Since the bottom of the storage platform 810 is fixed to a specific position of the first synchronous belt 824, when the upper surface of the first synchronous belt 824 moves, the storage platform 810 moves with the first synchronous belt 824.

[0104] The top of the storage unit 800 is provided with a clothes sensor 801, which is a photoelectric sensor. During the process of clothes being output from the clothes outlet into the storage unit 800, the light beam emitted by the clothes sensor 801 is blocked, so that the clothes sensor 801 feeds back a triggered signal. The storage unit 800 further comprises a first position sensor, which can be a touch switch arranged on the frame 821. When the right side of the storage platform 810 moves below the clothes outlet, the first position sensor is triggered. The storage unit 800 further comprises a second position sensor 802, which is a photoelectric sensor. The installation height of the second position sensor 802 is flush with the highest height that the storage platform 810 can reach. The installation height of the second position sensor 802 is a certain distance away from the clothes outlet, which is greater than the thickness of the folded clothes, so as to ensure that there is enough space above the storage platform to receive clothes. After the storage platform 810 receives clothes, the light beam emitted by the second position sensor 802 is blocked due to the thickness of the clothes, so that the second position sensor 802 feeds back a triggered signal. The storage platform 810 is controlled to descend by the vertical moving mechanism. When the upper edge of the clothes descends below the second position sensor 802, the second position sensor 802 feeds back a non-triggered signal. The storage platform 810 further comprises a third position sensor, which can be a touch switch arranged on the frame 821. When the left side of the storage platform 810 moves below the clothes outlet, the third position sensor is triggered.

[0105] During the process of clothes output, the horizontal moving mechanism is controlled by the folding machine to drive the storage platform 810 to move horizontally to the clothes outlet to receive clothes.

[0106] Specifically, the vertical moving mechanism is controlled by the folding machine to drive the storage platform 810 to rise to the highest height, and the horizontal moving mechanism is controlled to drive the storage platform 810 to move horizontally. When the folding machine receives a signal that the third position sensor is triggered, it is determined that the left side of the storage platform 810 moves below the clothes outlet, and the horizontal moving mechanism is controlled to stop driving, preparing to receive clothes.

[0107] The folding unit works, and the clothes are folded in the folding unit and output from the clothes outlet into the storage unit 800. When the folding machine receives a signal that the clothes sensor 801 is triggered, it is determined that clothes are output from the clothes outlet, and the horizontal moving mechanism is controlled to drive the storage platform 810 to move horizontally to the left to receive clothes. During the process of clothes output, the clothes sensor 801 always feeds back a triggered signal. When the folding machine receives a signal that the clothes sensor 801 is not triggered, it is determined that the clothes output is completed, and the horizontal moving mechanism is controlled to drive the storage platform 810 to stop moving, i.e. to complete a clothes receiving process.

[0108] In another aspect of the embodiment, the folding machine can measure the length D1 of the folded clothes by the length measuring module, and monitor the distance D2 of the movement of the receiving platform 810 by the distance measuring module. Specifically, the conveying device of the folding unit comprises a rotating roller and a conveying belt wound around the rotating roller, and the conveying belt is conveyed under the rotation of the rotating roller. An angle encoder is arranged on the rotating shaft of the rotating roller of the first extrusion conveying device 201, and cooperates with the first sensing unit 701. When the leading end and the trailing end of the clothes pass through the first sensing unit 701, the values of the angle encoder are recorded respectively. The length L of the clothes before folding can be calculated by the radius of the rotating roller measured in advance. An angle encoder is arranged on the rotating shaft of the rotating roller of the folding conveying device 300, and cooperates with the second sensing unit 702. The distance of the clothes conveyed in each stage during the folding process can be calculated, and the length D1 of the clothes after folding can be calculated in combination with the original length L of the clothes. An angle encoder is arranged on the rotating shaft of the first synchronous pulley 825, and the radius of the first synchronous pulley 825 is measured in advance. The distance D2 of the movement of the receiving platform 810 in the horizontal direction can be calculated in real time during the movement of the receiving platform 810. When the folding machine receives the signal that D2=D1, it is determined that the clothes output is completed, and the horizontal movement mechanism is controlled to stop the movement of the receiving platform.

[0109] In another aspect of the embodiment, the folding machine can also control the receiving platform 810 to stop moving by the signal fed back by the first position sensor. When the folding machine receives the signal that the first position sensor is triggered, it is determined that the right side of the receiving platform 810 has moved to the lower side of the clothes outlet, i.e., the clothes output is completed, and the horizontal movement mechanism is controlled to stop the movement of the receiving platform 810.

[0110] In a preferred aspect of the embodiment, the folding machine preferentially determines the end of the clothes output by the signal fed back by the clothes sensor 801, or preferentially determines the end of the clothes output by monitoring the distance of the movement of the receiving platform 810 by the distance measuring module, and then controls the receiving platform 810 to stop moving. The folding machine is also provided with the first position sensor. When the conditions for determining the end of the clothes output by the above two methods do not occur, but the first position sensor is triggered, the receiving platform 810 is controlled to stop moving. Since the end of the clothes output should occur before the right side of the receiving platform 810 moves to the lower side of the clothes outlet, when the receiving platform 810 is controlled to stop moving by the first position sensor, the situation that the clothes output is not completed but the receiving platform 810 has stopped moving will not occur. In the above aspect, the first position sensor is used as an auxiliary determination means. In the case that the clothes sensor 801 or the distance measuring module fails or fails, the control of the horizontal movement of the receiving platform 810 can also be realized.

[0111] After the clothes output is completed, the folding machine controls the vertical moving mechanism to drive the storage platform 810 to descend, and the descending height of the storage platform 810 is controlled by the second position sensor 802. Specifically, when the first piece of clothes is ready to be received, the height of the storage platform 810 is flush with the installation height of the second position sensor 802, and after the clothes receiving is completed, the second position sensor 802 is blocked, and a feedback triggered signal is generated. During the descending process of the storage platform 810, when the upper edge of the clothes just descends below the second position sensor 802, the signal feedback by the second position sensor 802 jumps from the triggered state to the non-triggered state. During the descending process of the storage platform 810, when the folding machine receives the signal that the second position sensor 802 is not triggered, it is determined that the storage platform 810 has descended to the position, and the vertical moving mechanism is controlled to stop the descending of the storage platform 810.

[0112] As a preferred embodiment of the present application, after the storage platform 810 stops descending, the folding machine controls the vertical moving mechanism to drive the storage platform 810 to ascend, and when the folding machine receives the signal that the second position sensor 802 is triggered, the vertical moving mechanism is controlled to stop the ascending of the storage platform 810. By triggering the second position sensor 802 during the ascending process of the storage platform 810, the stopping height of the storage platform 810 is controlled, which avoids the situation that the end of the clothes stays or drags at the clothes outlet during the descending process of the storage platform 810, continuously blocks the second position sensor 802, causes a false judgment, and causes the actual height of the upper edge of the clothes to be much lower than the height of the second position sensor 802 after the storage platform 810 stops moving. After the storage platform 810 stops descending, the clothes have been laid flat on the storage platform 810, and at this time, triggering the second position sensor 802 by controlling the ascending of the storage platform 810 can better position the height of the storage platform 810.

[0113] Preferably, when the folding machine receives the signal that the second position sensor 802 is triggered, the vertical moving mechanism is controlled to continue ascending the storage platform 810 by a certain height and then stop moving, which can more stably control the receiving height of the storage platform 810.

[0114] After the storage platform 810 stops moving in the vertical direction, the folding machine controls the horizontal moving mechanism to drive the storage platform 810 to move to the right to reset. When the folding machine receives the signal that the third position sensor is triggered, the horizontal moving mechanism is controlled to stop moving the storage platform 810, and the next piece of clothes is ready to be received.

[0115] The above process is cycled, the receiving platform 810 is lowered by a certain height after receiving each piece of clothing, and then is reset in the horizontal direction to prepare for receiving the next piece of clothing. The receiving unit 800 is also provided with a fourth position sensor for detecting whether the receiving platform 810 has been lowered to the lowest height. When the folding machine receives a signal that the fourth position sensor is triggered, it is determined that the receiving platform 810 has been lowered to the limit position, the folding unit is controlled to pause folding the clothes, and the user is reminded to take out the folded clothes from the receiving unit 800.

[0116] In a further preferred embodiment of the present embodiment, during the clothing output process, the folding machine controls the speed of the horizontal movement of the receiving platform 810 to match the speed of the clothing output by the folding unit, thereby achieving the effect of flattening the clothing. Preferably, during the clothing output process, the folding machine controls the second folding conveyor 302 and the third folding conveyor 303 to convey at a certain difference in conveying speed, thereby achieving the effect of flattening the clothing. More preferably, before the clothing contacts the receiving platform 810, the folding machine controls the horizontal movement mechanism to accelerate the receiving platform 810 to a speed that can flatten the clothing.

[0117] In the present embodiment, the folding machine controls the horizontal movement of the receiving platform to receive the clothing during the clothing output process, thereby achieving dynamic receiving that matches the clothing output process. The clothing sensor detects whether there is clothing output from the clothing outlet into the receiving unit 800, and then controls the horizontal movement of the receiving platform to receive the clothing, thereby making the control of the receiving platform more accurate. By providing multiple position sensors, the movement of the receiving platform is stopped according to the signals fed back by the position sensors, thereby making the position control of the receiving platform more accurate. The folding machine controls the receiving platform to lower by a certain height after receiving each piece of clothing, and then reset in the horizontal direction to prepare for receiving the next piece of clothing, thereby achieving continuous receiving of the clothing and high automation. By controlling the horizontal movement speed of the receiving platform to match the clothing output speed of the folding unit, the clothing is flattened during the receiving process, thereby ensuring the flatness of the clothing received by the receiving platform.

Although the present application has been disclosed as above with reference to the preferred embodiment, it is not intended to limit the present application.
