[0037]

[0038] In the first embodiment, please refer to Figure 1 , Figure 3 , Figure 4 ​The first swing lever assembly 15 comprises a first swing lever 151 and a swing lever driving unit 152. The swing lever driving unit 152 is fixed on the swing arm 12, and the swing lever driving unit 152 is connected with the first swing lever 151. The swing lever driving unit 152 is used to drive the first swing lever 151 to swing reciprocally between the working position and the nest position. The first swing lever 151 is used to support and swing the current raw material 5 in the second working position.

[0039] Initially, the suction cup assembly 14 is connected with the current raw material 5 by suction, and the first swing lever 151 is located in the nest position. When the current raw material 5 is located in the first working position 7, the first swing lever 151 abuts against the side surface of the current raw material 5, and the suction cup assembly 14 is separated from the current raw material 5.

[0040] When the current raw material 5 is located in the second working position, the first swing lever 151 is separated from the current raw material 5 to return to the nest position, and the current raw material 5 is placed on the plate chain conveyor 3. The first swing lever 151 is driven by the swing lever driving unit 152 to swing from the nest position to the working position, so that the first swing lever 151 abuts against the side surface of the current raw material 5, the suction cup assembly 14 is moved away, and the swing arm 12 continues to swing to place the current raw material 5. During the placing process, the first swing lever 151 can play a supporting role. After the first swing lever 151 swings to the second working position, the first swing lever 151 is driven by the swing lever driving unit 152 to swing from the working position to the nest position, and the current raw material 5 falls onto the plate chain conveyor 3. The whole process is fully automated, which is more efficient, lower in cost, and better in quality of the raw material 5.

[0041] In some embodiments, please refer to Figure 4 、 Figure 5 The upper end of the swing arm 12 is provided with a mounting seat 121. The swing lever driving unit 152 comprises a swing lever cylinder 1521, a first connecting shaft and a first connecting rod 1522. The swing lever cylinder 1521 is arranged on one side of the mounting seat 121, and the output shaft of the swing lever cylinder 1521 is hingedly connected with one end of the first connecting rod 1522. The other end of the first connecting rod 1522 is fixedly connected with the first swing lever 151. One end of the first connecting shaft is fixed on the mounting seat 121, and the other end of the first connecting shaft is connected with the first connecting rod 1522 through a bearing. The structure is simple, the cost is low, the space is avoided, and the operation efficiency is higher.

[0042] Specifically, please refer to Figure 4The output shaft of the swing rod air cylinder 1521 is fixedly provided with a connecting head 1523, and the other end of the connecting head 1523 is sleeved on the first connecting rod 1522. The output shaft of the swing rod air cylinder 1521 is extended to push the first connecting rod 1522 to rotate clockwise around the first connecting shaft, and the other end of the first connecting rod 1522 drives the first swing rod 151 to rotate from the working position to the nest working position. When the output shaft of the swing rod air cylinder 1521 is retracted, the connecting head 1523 pulls the first connecting rod 1522 to rotate counterclockwise around the first connecting shaft, and the other end of the first connecting rod 1522 drives the first swing rod 151 to rotate from the nest working position to the working position.

[0043] Preferably, the first swing rod assembly 15 further comprises a magnetic induction switch arranged on the mounting seat 121, which is used to detect whether the first swing rod 151 is in contact with the current raw material 5, thereby improving the safety performance. When the first swing rod 151 swings to the working position, the side surface of the first swing rod 151 is in contact with the current raw material 5, the magnetic induction switch is lighted, and the work is normal. If the current raw material 5 is located at the first working position 7, the magnetic induction switch does not sense the first swing rod 151 after a set time, an alarm is prompted, the suction cup assembly 14 continues to suck the current raw material 5, and the swing arm 12 stops swinging. The magnetic induction switch is not shown in the figure.

[0044] In some embodiments, referring to Figure 4 、 Figure 5 The suction cup assembly 14 comprises a suction cup driving unit 141, a universal seat 142 and a suction cup 143. The suction cup driving unit 141 is arranged on the other side of the mounting seat 121, the end of the suction cup driving unit 141 is fixedly connected with the universal seat 142, and the body of the suction cup 143 is movably connected to the universal seat 142. Since the placing angles of the raw materials 5 are different, the universal seat 142 can make the suction cup 143 rotate by 360° to adjust the suction surface, so that the suction cup 143 is more closely attached to the side surface of the current raw material 5 and is more firmly adsorbed. The suction cup driving unit 141 is used to drive the suction cup 143 to approach or move away from the current raw material 5, thereby improving the compatibility and ensuring that the suction cup 143 completely and firmly adsorbs the current raw material 5.

[0045] The body of the suction cup 143 is provided with an air inlet connector 1431, which is connected with an external air supply device, so as to facilitate the suction cup 143 to adsorb or release the current raw material 5.

[0046] Preferably, the suction cup driving unit 141 comprises a suction cup driving cylinder 1411, a second connecting shaft, a second connecting rod 1413 and a fixed plate 1414. The suction cup driving cylinder 1411 is fixed to the other side of the mounting seat 121, improving space utilization and structural compactness. The output shaft of the suction cup driving cylinder 1411 is fixedly connected with a fixed joint 1412, the other end of the fixed joint 1412 is hingedly connected with one end of the second connecting rod 1413, and the other end of the second connecting rod 1413 is fixedly connected with one end of the fixed plate 1414. One end of the second connecting shaft is fixed to the mounting seat 121, and the other end of the second connecting shaft is connected to the second connecting rod 1413 through a bearing. The other end of the fixed plate 1414 is connected with a universal seat 142, the transmission is stable, and the installation and disassembly are more convenient.

[0047] Preferably, the suction cup assembly 14 further comprises a spring 144, which is sleeved on the universal seat 142 and located between the other end of the fixed plate 1414 and the suction cup 143, providing a buffer space and being beneficial to protecting the suction cup 143 and the raw material 5, so that the suction cup 143 is more firmly adsorbed.

[0048] Preferably, the suction cup assembly 14 further comprises a photoelectric switch 145 for detecting whether the suction cup 143 adsorbs the current carried raw material 5, improving safety and efficiency of carrying. When the light of the photoelectric switch 145 is on, it indicates that the suction cup 143 is firmly adsorbed with the current carried raw material 5, and the driving assembly 13 can drive the swing arm 12 to rotate. When the light of the photoelectric switch 145 is still not on after the suction cup 143 is adjusted for several times, an alarm is prompted and the carrying of the raw material 5 is stopped.

[0049] In some embodiments, please refer to Figure 3 , the upper end of the swing arm 12 is provided with a guide rail 124 along the length direction thereof. The suction cup assembly 14 further comprises an adjusting cylinder 146 and a sliding seat 147. The mounting seat 121 is fixedly connected to one side of the sliding seat 147 through the connecting block 122, and the other side of the sliding seat 147 is slidingly connected to the guide rail 124. The body of the adjusting cylinder 146 is fixed to the swing arm 12, and the output shaft of the adjusting cylinder 146 is fixedly connected with the connecting block 122. When the suction cup 143 is adsorbed to the raw material 5, the air pipe of the suction cup 143 inhales air, and the air supply pipe of the adjusting cylinder 146 stops supplying air, so that the suction cup assembly 14 slides along the guide rail 124 under the self-weight force of the sliding seat 147, which can make the suction cup 143 adaptively adjust the gravity center position during the overturning process of the raw material 5, improve compatibility, be beneficial to protecting the raw material 5, and be more efficient. When the suction cup 143 releases the raw material 5, the air pipe of the suction cup 143 stops supplying air, and the air supply pipe of the adjusting cylinder 146 starts supplying air, so that the adjusting cylinder 146 pushes the mounting seat 121 and the suction cup assembly 14 thereon to return to the initial position.

[0050] In some embodiments, please refer to Figure 3 , Figure 4The pusher type sheet feeding machine 1 further comprises a second swing rod assembly 16 arranged at the lower end of the swing arm 12. The second swing rod assembly 16 abuts against the other side of the last raw material 5, so that the last raw material 5 is clamped and fixed between the suction cup assembly 14 and the second swing rod assembly 16 or between the first swing rod assembly 15 and the second swing rod assembly 16 to fix the last raw material 5, which can prevent the last raw material 5 from slipping and improve the efficiency of the carrying and protect the raw material 5.

[0051] Specifically, the second swing rod assembly 16 has the same structure as the first swing rod assembly 15, and the rotation direction of the second swing rod 161 of the second swing rod assembly 16 is opposite. When the suction cup 143 adsorbs and rotates the last raw material 5 to the vertical position, the second swing rod 161 swings to the other side of the lower end of the raw material 5 and abuts against the lower end of the raw material 5, which can prevent the raw material 5 from slipping during the swinging process and improve the efficiency of the carrying.

[0052] In some embodiments, please refer to Figure 4 The driving assembly 13 comprises a servo motor, a flange plate and a speed reducer. The flange plate is arranged on the base 11, and the servo motor and the speed reducer are fixed on the flange plate.

The swinging angle of the swing arm 12 can be pre-set in the control system, and the rotation amplitude of the swing arm 12 can be controlled through the rotation of the servo motor, so as to realize the precise cooperation of each component, improve the efficiency of the automatic operation and reduce the cost. The servo motor and the speed reducer are not shown in the figure.

[0053] In the second embodiment, please refer to Figure 6 In addition to the structure mentioned in the first embodiment, the pusher type sheet feeding machine 1 further comprises a transmission rod assembly 17. The transmission rod assembly 17 comprises a supporting arm 171 and a transmission rod unit 172.

The second transmission rod 1722 is slidingly connected to the base 11, so that the second transmission rod 1722 can move horizontally and reciprocally, thereby improving the accuracy of the reciprocating movement of the first transmission rod 1721 and the third transmission rod 1723, accurately controlling the running path of the support arm 171, and improving the accuracy and efficiency of the carrying. The other end of the third transmission rod 1723 is hingedly connected to the support arm 171. The first transmission rod 1721, the second transmission rod 1722 and the third transmission rod 1733 are all located on the lower side of the support arm 171, avoiding work interference, compact structure and higher space utilization.

[0055] Specifically, the lower end of the support arm 171 is connected to the output shaft of the speed reducer through a bearing. The lower end of the swing arm 12 is provided with a plurality of fixed holes 125 along the circumferential side thereof, facilitating adjustment of the position of the first transmission rod 1721 installed on the swing arm 12 according to different actual situations, so as to adapt to the amplitude of the swing of the support arm 171 driven by the transmission rod assembly 17.

In addition, a lug 1714 is protrudingly arranged on the side edge of the first branch 1711, and the other end of the third transmission rod 1723 is hingedly connected to the lug 1714.

[0057] Please refer to Figure 1 , Figure 2 The upper sheet system further comprises a feeding detection assembly 6. The trolley 4 is placed on the feeding conveyor belt 2, the plate chain conveyor belt 3 is arranged in a spaced manner with the feeding conveyor belt 2, and the push piece type sheet feeding machine 1 is arranged between the plate chain conveyor belt 3 and the feeding conveyor belt 2. The feeding detection assembly 6 is arranged on one side of the feeding conveyor belt 2, and is used to detect whether the axis of the swing arm 12 and the swing axis of the currently carried raw material 5 are located on the same straight line.

[0058] The loading detection assembly 6 comprises a detection electric eye 61 and a bracket 62. The bracket 62 is arranged between the swing arm 12 and the current raw material 5, and coaxially arranged. The detection electric eye 61 is arranged on the bracket 62. When the feeding conveyor belt 2 forwards the trolley 4 by one station, the current raw material 5 is located on the loading station. At this time, the lower end of the current raw material 5 rotates around the same axis as the swing arm 12. The detection electric eye 61 detects that there is a raw material 5 on the loading station. The feeding conveyor belt 2 stops conveying. The driving assembly 13 is started to drive the swing arm 12 to rotate, so that the suction cup 143 of the suction cup assembly 14 adheres to the side of the current raw material 5 to perform the suction work. The swing arm 12 reversely rotates to drive the suction cup assembly 14 and the current raw material 5 to rotate to the first station 7.

[0059] In the first embodiment, the first swing rod 151 swings to the working position, so that the first swing rod 151 supports the current raw material 5 to rotate and drop onto the plate chain conveyor belt 3. The suction cup 143 reversely rotates to be extracted to provide space for the current raw material 5 to drop. Moreover, when the first swing rod 151 reversely moves out, the current raw material 5 loses the supporting force and falls onto the plate chain conveyor belt 3. The plate chain conveyor belt 3 is started to drive the raw material 5 thereon to convey to the corresponding position. The detection electric eye 61 detects that there is no raw material 5 on the loading station. The detection electric eye 61 light is on. The feeding conveyor belt 2 forwards the trolley 4 by one station, so that the next raw material 5 to be carried is located on the loading station. The detection electric eye 61 light is off, waiting for the next round of carrying work.

[0060] In the second embodiment, when the suction cup assembly 14 and the current raw material 5 rotate to the first station 7, the supporting arm 171 reversely swings to the first station 7 under the driving action of the transmission rod assembly 17. The first swing rod 151 swings to the working position. The suction cup 143 reversely rotates to be extracted to provide space for the current raw material 5 to drop. The swing arm 12 reversely rotates to return to the loading position to perform the next round of loading work. Under the driving action of the transmission rod assembly 17, the supporting arm 171 drives the first swing rod assembly 15 and the current raw material 5 thereon to continue to drop. When the swing arm 12 returns to the loading position, the supporting arm 171 and the first swing rod assembly 15 move to the second station. The first swing rod 151 reversely rotates to be separated from the current raw material 5. The current raw material 5 falls onto the plate chain conveyor belt 3 under the action of the gravity, completing one round of raw material 5 carrying work.

[0061] The loading method of the sheet loading system, comprising the sheet loading system of any one of the above, which comprises:

[0062] Step S1, the swing axis of the current carrying raw material 5 at the feeding station is on the same straight line with the rotation axis of the swing arm 12; the driving assembly 13 drives the swing arm 12 to swing to the feeding station and adsorb the current carrying raw material 5; the driving assembly 13 drives the swing arm 12 to rotate reversely to make the suction cup assembly 14 and the current carrying raw material 5 swing to the first station 7 based on the lower end of the current carrying raw material 5 as the axis;

[0063] Step S2, the first swing rod assembly 15 supports the current carrying raw material 5, the suction cup assembly 14 is separated from the current carrying raw material 5, and the current carrying raw material 5 moves to the second station under the support of the first swing rod assembly 15;

[0064] Step S3, the first swing rod assembly 15 is separated from the current carrying raw material 5, and the current carrying raw material 5 falls to the plate chain conveyor 3 under the action of gravity, and the plate chain conveyor 3 conveys the current carrying raw material 5 to the next station;

[0065] Step S4, the feeding conveyor 2 conveys the next piece of raw material 5 to be carried to the feeding station, and the steps S1-S3 are repeated.

[0066] In step S1, specifically, when the detection electric eye 61 detects that the feeding station is provided with the raw material 5 to be carried, the light of the detection electric eye 61 is off, the feeding conveyor 2 stops conveying, the driving assembly 13 is started to drive the swing arm 12 to rotate, so that the suction cup 143 of the suction cup assembly 14 is attached to the side of the current carrying raw material 5 for adsorption work. The swing arm 12 reversely rotates to drive the suction cup assembly 14 and the current carrying raw material 5 to rotate to the first station 7.

[0067] If the feeding station is empty, the light of the detection electric eye 61 is always on, the control system controls the feeding conveyor 2 to start, and the trolley 4 on the feeding conveyor 2 is conveyed to the feeding station position by a distance of the thickness of the raw material 5 to be carried, so as to convey the next piece of raw material 5 to be carried to the feeding station. At this time, the light of the detection electric eye 61 is off, and the next round of carrying work of the push piece type sheet feeding machine 1 is carried out.

[0068] Among them, when the current carrying raw material 5 is at the first station 7, the horizontal angle between the side of the current carrying raw material 5 and the side of the plate chain conveyor 3 is 76°-86°. When the suction cup 143 of the suction cup assembly 14 adsorbs the side of the current raw material 5, the suction cup 143 can rotate 360° through the universal seat 142, so that the disc opening of the suction cup 143 can automatically adjust the position to adsorb firmly on the side of the current carrying raw material 5, and the compatibility is improved.

[0069] Preferably, during the swinging process of the suction cup assembly 14, the air supply pipe of the adjusting cylinder 146 stops supplying air, the air pipe of the suction cup 143 always supplies air, the sliding seat 147 loses the supporting force, and under the action of the weight of the sliding seat 147, the suction cup assembly 14 is driven to slide downward by a certain distance, so that the current raw material 5 can adapt to the center of gravity during swinging to adjust the position of the suction cup assembly 14, and the accuracy and efficiency of swinging are improved. When the suction cup 143 stops supplying air, the adjusting cylinder 146 starts to supply air, and the adjusting cylinder 146 pushes the sliding seat 147 to the upper end of the guide rail 124, and the suction cup assembly 14 is synchronously moved upward and separated from the current raw material 5.

[0070] Specifically, the suction cup 143 is provided with a photoelectric switch 145, which can detect the distance from the surface of the current raw material 5, and then compare it with the set value, so as to determine whether the suction cup 143 is firmly attached to the current raw material 5.

[0071] In step S2, when the suction cup assembly 14 swings the current raw material 5 to the first station 7 with the swinging axis of the swing arm 12 as the axis, the output shaft of the swing rod cylinder 1521 is extended to drive the first swing rod 151 to rotate counterclockwise around the first connecting shaft, so that the first swing rod 151 swings from the nest station to the working station, and the first swing rod 151 abuts against the side of the current raw material 5 to support the current raw material 5. At this time, the suction cup assembly 14 is separated from the current raw material 5. Wherein, when the first swing rod 151 is in the nest station, the first swing rod 151 will not interfere with the current raw material 5. The first swing rod assembly 15 supports the current raw material 5 to move to the second station.

[0072] In step S3, since the raw material 5 is a rough blank, the first swing rod 151 can be separated from the current raw material 5 at a certain height from the plate chain conveyor 3, so that the current raw material 5 automatically falls onto the plate chain conveyor 3. Of course, the first swing rod 151 can also be moved away after the current raw material 5 is conveyed onto the plate chain conveyor 3. The plate chain conveyor 3 conveys the current raw material 5 to the next station, and synchronously, the swing arm 12, the suction cup assembly 14 and the first swing rod assembly 15 are reset.

[0073] In step S4, when the current raw material 5 is placed on the plate chain conveyor 3, the detection electric eye 61 is lighted, the feeding conveyor 2 is started and moves to the feeding station by one stroke, which is the thickness of one raw material 5, so as to convey the next raw material 5 to be carried to the feeding station. When the detection electric eye 61 detects that there is a raw material 5 on the feeding station, the detection electric eye 61 is extinguished, and the control system controls the driving assembly 13 to start the next round of carrying operation, and the steps S1-S3 are repeated.

[0074] In step S5, when the current raw material 5 is the last raw material 5 on the trolley 4, the lower end of the raw material 5 is not supported, so that the lower end of the raw material 5 is easy to slip during the swinging process, affecting the efficiency of the carrying. Therefore, a set of second swing lever assemblies 16 are arranged on the back side of the lower end of the current raw material 5 to provide a swinging support force to prevent the raw material 5 from slipping during the swinging process.

[0075] Before the suction disc assembly 14 rotates the current raw material 5 to the vertical position, the second swing lever assembly 16 swings to the side of the current raw material 5 away from the suction disc assembly 14 and abuts against the lower end of the back side of the current raw material 5, so that the current raw material 5 does not slip when it swings to the other side. When the current raw material 5 swings to the second station, the first swing lever assembly 15 and the second swing lever assembly 16 are separated from the current raw material 5, so that the current raw material 5 is lowered onto the plate chain conveyor 3. At this point, the carrying of the raw materials 5 on the trolley 4 is completed, the trolley 4 is moved out of the feeding conveyor 2, and the feeding is restarted, so that the next round of work can be performed.

[0076] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, wherein the same parts are denoted by the same reference numerals. Therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
