Description

Technical Field

[0001] The present invention belongs to the field of mechanical automation technology, and specifically relates to the design and control of a leather cover automatic fitting device for a Pilates core bed box. The device realizes the automation of the entire box making process from unfolding the leather cover to fitting it into a wooden box by setting an automatic supply mechanism, an opening mechanism, a spreading mechanism, a moving mechanism, a fitting mechanism, etc. Background Art

[0002] Traditional craftsmanship of handmade leather box

[0003] Before this patent design, the mainstream process of putting leather box covers on wooden boxes was still manual operation. Workers needed to manually unfold the leather box cover, adjust it to the corresponding shape, then put it on the wooden box body and fix it with nails. This manual operation process is inefficient and cannot be mass-produced. At the same time, the repeated unfolding of the leather and binding and fixing operations are also laborious, which increases the labor intensity of workers.

[0004] Specifically, workers first need to unfold the leather box cover by hand, gradually stretch out the wrinkles on the four sides and adjust it to the shape of a three-dimensional box. This unfolding process requires controlling the strength according to the thickness and hardness of the leather material to avoid strain. After the unfolding is completed, the worker puts the wooden box body into the unfolded leather box cover, manually adjusts the matching relationship between the two to ensure that it is completely covered. Then use staplers and other fasteners to nail the multilateral edges of the leather box cover to the wooden box to complete the set. The whole process involves a large number of manual operations, with low production efficiency and cannot be automated.

[0005] In summary, the traditional process of handmade leather boxes is inefficient and labor-intensive, and urgently needs to be replaced by automated machinery, which is the main problem solved by this patent. Summary of the invention

DETAILED DESCRIPTION

[0038] Below are all the attached Figure 1-10 The present invention is further described by way of the following embodiments:

[0039] Example 1

[0040] Attached Figure 1-2 The box 01 equipped with the Pilates core bed is shown, and its main body is a hexahedral wooden box 012. In order to enhance the comfort and safety of users during training, the outer surface of the wooden box is covered with a layer of sponge. To protect the sponge, it is wrapped with a leather cover 011. The current leather cover 011 needs to be put on manually. The wooden box is large in size, and the leather is tightly wrapped. The cover must ensure that each surface is neat, which is time-consuming and tiring for workers.

[0041] like Figure 3 ―4 shows a leather suit device for a Pilates core bed box, comprising: a frame 11, a feeding mechanism 12 arranged at the input end of the frame 11, an opening mechanism 13 and a leather suit opening mechanism 14 arranged at the rear end of the feeding mechanism 12, a transverse frame 15 for moving the leather suit opening mechanism 14, a leather suit mechanism 16 arranged between two parallel transverse frames 15, an installation moving frame 17 for installing the leather suit mechanism 16, a wooden box pushing mechanism 18 arranged below the leather suit mechanism 16, and a shipping mechanism 19 for moving the leather suit that has been put on out of the leather suit device.

[0042] The working process is as follows: the leather cover 011 is sequentially transported to the rear end by the feeding mechanism 12, and the mouth of the leather cover 011 is first opened by the opening mechanism 13, and then it is unfolded and flattened after entering through the stretching mechanism 14. At this time, the leather cover is in an open state. The flattened leather cover is driven by the lateral frame 15 to move the leather cover stretching mechanism 14 to the bottom of the leather cover fitting mechanism 16 above. At this time, the wooden box pushing mechanism 18 located below starts to work, and pushes the wooden box 012 sequentially to the bottom of the leather cover fitting mechanism 16. The leather cover fitting mechanism 16 descends, and the unfolded leather cover is put on the wooden box to complete the fitting. The finished box 01 after fitting is finally transported to the finished product area by the shipping mechanism 19. Figure 3 As shown, the rack 11 is mainly composed of a frame 111 and a guard frame 112 .

[0043] The feeding mechanism 12 is one of the key components for realizing automatic feeding, and its core function is to transport the leather cover materials to be processed to the subsequent processing steps in an orderly and continuous manner.

[0044] Specifically, the feeding mechanism of the present invention can use a standard conveyor belt structure to realize automatic feeding of the leather case. The conveyor belt is composed of a driving motor and a belt, and the leather case material is sequentially advanced by the drive of the belt. Compared with manual feeding, the automatic feeding by the conveyor belt can ensure the continuity of the entire production process, laying a foundation for the automation and standardized production of subsequent processes.

[0045] In addition to the conveyor belt structure, the feeding mechanism of the present invention can also adopt other structures that can realize the automatic feeding function, such as a propulsion mechanism provided with a pneumatic or mechanical clamping device. The propulsion mechanism can clamp the front and rear edges of the leather cover material and push it forward through a pneumatic or mechanical driving source, thereby realizing the purpose of automatic sequential feeding.

[0046] The use of an automated feeding mechanism replaces the manual feeding process, which not only improves the automation level of the production process, but also increases the output and reduces the labor intensity. The use of this mechanism is an important guarantee for the invention to achieve efficient automatic assembly.

[0047] The opening mechanism 13 is a key component for realizing the automatic opening of the leather cover material. The mechanism uses the thinness and flexibility of the leather cover material to make the leather cover open by negative pressure adsorption. The opened leather cover can be prepared for subsequent expansion, set-fitting and other processes.

[0048] Specifically, if Figure 5As shown, the opening mechanism 13 includes two parts: a nozzle assembly and a drive system. The nozzle assembly includes two nozzles 131 for negative pressure adsorption of the leather case; an air nozzle 132 for providing negative pressure for the nozzle 131; an adapter plate 133 for fixing the nozzle 131 and the air nozzle 132; and a guide column 134 for guiding the movement of the adapter plate. The drive system includes a first cylinder 131 for driving the adapter plate to rise and fall; a mobile frame 135 for installing the guide column 134; a mobile seat 136 for installing the mobile frame 135; The drive system can be a screw drive mechanism, and a pneumatic cylinder drive mechanism can be used. That is, a pneumatic cylinder is installed on the mobile seat, and the expansion and contraction of the pneumatic cylinder drives the mobile seat to move, so as to adjust the position of the nozzle. The pneumatic cylinder has a simple and reliable structure, and the movement is flexible and fast. It can also use a delay belt, a gear rack and other mechanisms. That is, a delay belt transmission or a rack and a gear are engaged to realize the linear reciprocating motion of the mobile seat, thereby driving the nozzle to move.

[0049] When working, the driving system drives the moving seat to move, and the position of the suction nozzle can be adjusted. Under the drive of the first cylinder, the adapter plate 133 descends, and the double suction nozzles 131 adsorb one surface of the leather case, and the adapter plate 133 rises to open the leather case. In this way, the opening mechanism automatically completes the preparation process of opening the leather case by using the negative pressure of the airflow.

[0050] The leather case opening mechanism 14 is a key device for automatically opening the four corners of the leather case. It works closely with the opening mechanism to open the four corners of the leather case immediately after it is opened. Figure 6As shown, the leather cover opening mechanism 14 includes four support rods 141 and support rod arms 142, a guide rod 143 for fixing the support rod arms 142, a riding frame 144 for rotating the support rod arms 142, a fixed beam 145 for installing the riding frame 144, a bevel gear 146 for driving the riding frame 144, a beam plate 147 for fixing two guide rods 143, a screw shaft 148 for driving the guide rods 143 to extend and retract, and a second motor 022 for driving the screw shaft 148, one end of the support rod 141 is fixed to the outer end of the support rod arm 142, the inner ends of the two support rod arms 142 are respectively fixed to the two guide rods 143, and the guide rod 143 is a reinforced A cylindrical rod with a long key groove is provided, one end of which is fixed to the support arm 142, and the other end is fixed to the two ends of the beam plate 147. The middle section is movably mounted in the corresponding axial hole of the riding frame 144 through a key fit; the riding frame 144 is rotatably mounted on the fixed beam 145 with the guide rod 143 as the mounting axis, and a semi-circular tooth surface C1 is processed on one of the upper and lower surfaces with the hole axis of the mounting shaft hole as the center of the circle, and the semi-circular tooth surface C1 is meshed with the bevel gear teeth 146. In some embodiments, semi-circular tooth surfaces C1 are provided on both the upper and lower surfaces to meet the respective meshing of the upper and lower riding frames 144, increase the meshing surface, and improve the matching stability. The rotation of the riding frame 144 can cause the guide rod 143 to rotate, and the rotation of the guide rod 143 drives the support arm 142 to swing, and the swing of the support arm 142 drives the support rod 141 to flip, and the two parallel support rods 141 flip toward each other, and when the distance is close, they are retracted, and when the distance is far away, they are open (corresponding to the four corners of the leather case when open). The front and rear extension of the support rod 141 is driven by the screw shaft 148, and the screw shaft 148 is driven by the second motor 022. The rotating screw shaft 148 pushes the support rod 141 to move forward and backward through the beam plate 147 and the guide rod 143. The fixed beam 145 is fixed on the gear shaft 152 of the transverse frame 15, and the bevel gear 146 is fixed on the gear seat 154 of the transverse frame 15 in a non-rotatable manner, and the bevel gear 146 is divided into two halves, and the tooth surface of each half is meshed with the corresponding half circular tooth surface C1 of the riding frame 144. The purpose of the two halves is to adapt the direction of the teeth. The leather cover opening mechanism causes the riding frame to mesh with the bevel gear 146 through the rotation of the fixed beam, and the riding frame drives the support rod 141 to rotate. The fixed beam rotates forward and backward to switch the support rod 141 between folding and unfolding. The opening mechanism automatically and accurately replaces manual opening, and is one of the key components for realizing the automation of the entire line. It lays the foundation for the subsequent wooden box fitting and molding process.

[0051] The transverse moving frame 15 is an automated mechanism for realizing the transverse movement of the leather cover opening mechanism 14, and also provides movement switching between the horizontal direction and the vertical direction.

[0052] Specific structure such as Figure 6-7As shown, it mainly includes a motion actuator and a driving mechanism. The motion actuator includes: a gear 151, a gear shaft 152, a rack 153, a gear seat 154, a slide seat 155, a moving block 156, a threaded shaft 157 and a transverse frame beam 158. They form a mechanical transmission chain through meshing, connection, sliding, etc., and finally drive the leather cover opening mechanism to achieve transverse movement on the transverse frame.

[0053] The driving mechanism includes a third motor 023 and its transmission, which drives the threaded shaft 157 to rotate. The rotation of the threaded shaft drives the slide seat and the leather cover opening mechanism to move horizontally through the moving block to complete the lateral movement.

[0054] Compared with manual operation, the lateral moving frame combined with automatic control can quickly and continuously drive the leather cover opening mechanism to move and position in the horizontal direction, providing accurate parts supply for subsequent set-up processes. It is highly coordinated with the leather cover opening mechanism and other mechanisms and is an important part of realizing the automatic production process.

[0055] The movement of the transverse frame is precisely controlled and automated by the motor drive mechanism. The third motor 023 drives the threaded shaft 157 to rotate forward and backward. The rotation of the threaded shaft drives the moving block 156 to move horizontally through the thread transmission with the moving block, thereby driving the entire slide 155 and the leather cover opening mechanism 14 to move horizontally on the transverse frame beam 158.

[0056] At the same time, the gear seat 154 installed on the slide 155 meshes with the fixed rack 153, and is forced to drive the gear 151 to rotate during the movement. The gear 151 transmits motion through the gear shaft 152 and drives the coaxial fixed beam 145 to rotate, driving the entire leather case opening mechanism 14 to rotate around the vertical axis. In this way, the vertical flip of the posture is achieved while moving horizontally.

[0057] Finally, the leather cover opening mechanism can realize two composite movements of lateral movement and vertical flipping on the transverse frame. This mechanism enables the leather cover to accurately reach the designated suiting position and adjust it to a vertical lowering state, perfectly connecting with the subsequent suiting station, providing hardware support for the realization of automated production processes. The transverse frame is equipped with standard mechanisms such as gears, racks, slides, and screws. The third motor drives the screw to rotate, driving the slide and the installed gear to make linear reciprocating motion. At the same time, the gear rotates under the meshing action of the rack, thereby driving the fixed beam and the leather cover opening mechanism connected to it to complete translation and rotation movements. In this way, the transverse frame can accurately and automatically move the unfolded and expanded leather cover from the opening mechanism to the designated suiting position, preparing for the subsequent suiting process. The transverse frame mechanism cooperates with the leather cover opening mechanism and is one of the key components for realizing automatic transportation.

[0058] The leather case fitting mechanism 16 is a device for realizing the key automation process of accurately lowering the leather case and fitting it into the wooden box. Figure 7 shown.

[0059] The mechanism is mainly composed of a lifting actuator and a driving mechanism. The lifting actuator includes a vertically arranged lifting rail 161, a side support 162 with an opening at the lower end, a pressing block 163 and a suction cup 165 inside the side support. The wooden box is placed under the side support, the pressing block applies pressure to fix the edge of the leather cover, the side support descends, driving the leather cover to move down and cover the wooden box, and then the suction cup stabilizes the positioning of the leather cover to complete the set.

[0060] The driving mechanism includes a lifting rail seat 166, a gear set 167, etc. The lifting rail seat is fixed on the frame, and the gear set is engaged with the lifting rail. Its drive drives the lifting rail to rise and fall, and then drives the side support and the leather cover to move down accurately. A pneumatic interface 164 is also provided to provide an air source for the pressing block.

[0061] The fitting mechanism automatically, quickly and accurately completes the fitting of the leather case to the wooden box. It cooperates with other mechanisms and is one of the key components for realizing full-automatic production.

[0062] The leather case fitting mechanism 16 is arranged on the four sides of the leather case to form a rectangular frame structure. The frame includes four mutually perpendicular lifting rails 161, which are respectively fixed in the corresponding rail grooves of the lifting rail seat 166; four side brackets 162 are welded to the lower end of the rails, and pneumatic flip-type pressing blocks 163 are provided on the front and rear side brackets. A plurality of suction cups 165 are also provided to absorb and position the leather case.

[0063] When working, the lifting mechanism drives the rectangular frame to move up and down as a whole. After it drops to the right position, the four side supports cover the leather case with the wooden box in the middle; the front and rear pressure blocks turn inside out under the drive of the air source to apply pressure to the leather case; at the same time, the suction cup absorbs the leather case to fix its position. In this way, the automatic control of the precise placement of the leather case is realized.

[0064] In terms of drive, a gear set 167 is provided at one end of the lifting rail, which realizes the lifting of the frame by meshing with the rack 171 on the side of the mounting mobile frame 17. The pneumatic and vacuum interfaces provide working media for the pressing block and the suction cup.

[0065] The structure integrates adsorption, compression and mechanical lifting, and realizes automatic drive and precise control of the leather case setting process. It cooperates with other parts of the whole line to greatly improve the degree of production automation.

[0066] The installation moving frame 17 is an automatic transmission mechanism for realizing the reciprocating movement of the leather case set mechanism. Figure 8 As shown, it mainly includes an actuator and a driving mechanism.

[0067] The actuator includes: a rack 171, a box 172, a top plate 173, a mounting plate 174, etc., which are fixedly connected together to form a whole with the leather case set mechanism 16. The guide column 175, the slider 177 and the slide rail 178 realize the smooth and accurate movement of the mechanism.

[0068] The driving mechanism includes a second cylinder 032 and an external air source. The cylinder acts on the mounting plate 174 to drive the entire moving mechanism to move vertically, thereby driving the leather case set mechanism to move up and down. At the same time, the slider cooperates with the sprocket to drive the entire mechanism to move back and forth horizontally on the slide rail, that is, to cycle between the opening station and the wooden box station.

[0069] In this way, the moving mechanism drives the set mechanism to move precisely in the vertical and horizontal directions, and finally realizes the automatic fixed-point set of the leather cover and the wooden box. It cooperates with other parts of the whole line to realize the automation of the production process.

[0070] The wooden box pushing mechanism 18 realizes the automatic supply and precise positioning of the wooden box through the components such as the elevator, positioning bar, and air nozzle driven by the motor. The working process is:

[0071] 1. The wooden boxes are placed sequentially on the handling table of the elevator 181 by the preset table 188;

[0072] 2. The fourth motor 024 drives the elevator to move up and down, and delivers the wooden box to the specified height in the positioning bar 184;

[0073] 3. The induction switch controls the elevator to stop, and the air nozzle 185 sprays air to the side of the wooden box, using the air pressure to push the wooden box into the positioning bar 184 and return it to its position accurately;

[0074] 4. After the positioning is completed, the wooden box is sent to the designated position directly below the leather case assembly mechanism 16 by the elevator, so as to facilitate the subsequent assembly.

[0075] In this way, the mechanism realizes automatic and precise control of the height and position of the wooden box, so that the wooden box and the leather set mechanism can be accurately docked, which is an important guarantee for realizing automatic box skinning.

[0076] The delivery mechanism 19 uses rollers 192 arranged in rows to drive the finished box 01 to be transported outwards:

[0077] 1. The box 01 after the initial set is placed on the platform of the bed frame 191 of the shipping mechanism by the leather set mechanism 16;

[0078] 2. The roller drives the box out;

[0079] 3. Finally, it is transported to the transfer point at the end of the bed frame 191, and then transported by the transfer mechanism.

[0080] In this way, the automatic output of the finished product is achieved through simple roller conveying.

[0081] Referring to all the attached drawings, the assembly process is as follows:

[0082] 1. Before work, the operator places the leather case material flat on the feeding mechanism in the correct direction of the case mouth. At the same time, the wooden boxes are loaded onto the lifting platform of the box pushing mechanism through the preset table sequence.

[0083] 2. The leather case is sent to the opening mechanism, and the negative pressure suction nozzle sucks the side of the leather case to lift it up to form an opening; after release, the double-axis support rod extends into the interior from the leather case opening.

[0084] 3. The riding frame on the opening mechanism drives the double support rods to flip and stand up, and at the same time the guide mechanism drives them to flip and unfold outward, opening the four corners of the leather cover to form a three-dimensional box.

[0085] 4. The mobile frame drives the set mechanism to move to the top of the open leather case, and presses down to cover it. The pressure block and the suction cup fix the shape of the leather case. The mobile frame retreats and the support rod withdraws.

[0086] 5. At the same time, the elevator raises the wooden box to the corresponding height of the suiting mechanism and accurately pushes it into the leather case to complete the suiting. The elevator descends and the finished box is sent to the shipping mechanism.

[0087] 6. The roller group of the delivery mechanism conveys the finished boxes out of the production line in sequence. At this point, the entire automated packaging process is completed.

[0088] Each actuator is precisely driven by a motor or cylinder and is equipped with displacement and pressure sensors to achieve real-time monitoring and feedback control of process parameters to ensure assembly quality.

[0089] Example 2

[0090] The bevel gear 146 in the leather cover opening mechanism 14 is changed from a fixed state driven by linkage to a state driven by an independent power source. Specifically:

[0091] In the leather cover opening mechanism 14, in addition to the original second motor 022, a third motor is provided to independently drive the bevel gear 146. The bevel gear 146 is separated from the fixed connection with the gear seat 154 of the original transverse frame 15 and is rotatably provided in the gear seat 154; the output shaft of the third motor is fixedly connected with the bevel gear 146 to drive it to rotate.

[0092] In this way, the drive of the bevel gear 146 can be independent of other transmission mechanisms, which has the following advantages:

[0093] 1) The speed, direction, torque and other parameters of the bevel gear 146 can be accurately controlled to improve the transmission accuracy, which is beneficial to the compound motion control of the strut 141;

[0094] 2) Power source redundancy, that is, the gears can still be driven by the third motor to ensure system reliability without the original compound linkage mechanism;

[0095] 3) Less noise and vibration; smoother transmission.

[0096] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
