[0015] The beneficial effects of the present invention are:

[0016] The present invention can cooperate with the truss manipulator device to realize accurate and efficient sleeve bagging operation, greatly reducing the manpower input cost. The moving mechanism can drive the upper movable tray to move left and right and front and back on the support platform. It adopts a high-precision guide rail and servo motor combination. The servo motor can accurately control the rotation angle and speed according to the command of the control mechanism, and convert it into a linear displacement of the upper movable tray through the screw nut pair, so as to realize high-precision positioning in the left and right and front and back directions, ensuring that the sleeve can be accurately placed in the predetermined position during the sequential discharge process, and arranged neatly and orderly, so as to prepare for the subsequent batch pushing and bagging. When the number of sleeves on the upper movable tray reaches the set number, the moving mechanism can accurately dock the upper movable tray with the lower plate of the bag support, so as to ensure that the sleeve can smoothly transition from the tray to the lower plate of the bag support, and avoid the sleeve from falling or getting stuck due to inaccurate docking. The action of the push cylinder is controlled by the control mechanism, and the control mechanism can adjust the telescopic speed and strength of the push cylinder according to the preset program to ensure that the sleeve smoothly enters the packaging bag and is pushed onto the bagging flap. The bagging flap is hinged at the front middle part of the bagging support. Its design cleverly utilizes the characteristics of gravity and mechanical structure. When the push cylinder pushes the packaging bag with an appropriate amount of sleeve onto the bagging flap, the bagging flap flips to the front and lower part of the support platform under the action of increased gravity. This automatic flipping and unloading method reduces human intervention and improves the unloading speed. When the packaging bag needs to be opened, the control mechanism issues a command, the piston rod of the bag-opening cylinder retracts, and pushes the upper bag-opening plate to move upward relative to the lower bag-opening plate. Since both the lower bag-opening plate and the upper bag-opening plate extend forward, they can adapt to packaging bags of different sizes and ensure that they are fully opened in the front and rear directions during the opening process, providing a suitable entrance space for the smooth loading of the sleeve, and ensuring the consistency and stability of each bag-opening operation, avoiding difficulties in bagging the sleeve or damage to the packaging bag due to insufficient or excessive bag-opening.

[0026] The moving mechanism is used to drive the upper moving material tray 1215 to move left and right and front and back on the supporting platform to realize the sequential discharge of the sleeves on the upper moving material tray 1215, and when the number of sleeves on the upper moving material tray 1215 reaches the set number, the upper moving material tray 1215 is controlled to dock with the bag-supporting lower plate 114, and the pushing cylinder 129 is used to push the sleeves on the upper moving material tray 1215 onto the bag-supporting lower plate 114 through the pushing baffle 1212 and then push them into the packaging bag jointly opened by the bag-supporting lower plate 114 and the bag-supporting upper plate 116, and then continue to push the packaging bag with an appropriate amount of sleeves onto the bag-filling flap 111, so that the bag-filling flap 111 flips toward the front and lower part of the supporting platform under the action of increased gravity, so as to facilitate the unloading of the packaging bag; the control mechanism 13 is used to control the operation of the bag-supporting cylinder 1111, the moving mechanism and the pushing cylinder 129. The bag-supporting cylinder 1111 pushes the bag-supporting upper plate 116 downward, and the empty packaging bag is put on the bag-supporting lower plate 114 and the bag-supporting upper plate 116. Then, the bag-supporting cylinder 1111 moves the bag-supporting upper plate 116 upward, and the packaging bag can be fully expanded.

[0027] like Figure 1 , 2 As shown, the left and right ends of the top of the bag support lower plate 114 are provided with enclosures to prevent the sleeve from falling and deflecting during the pushing process; the top front end and the left and right ends of the bag filling flap 111 are also provided with enclosures. The bag filling bracket includes two vertical support plates 115 fixed to the front side of the support platform symmetrically, two horizontal support plates 113 fixed to the inner side of the middle of the two vertical support plates 115 symmetrically and extending forward, and a cylinder support plate 118 fixed to the top of the two vertical support plates 115; the bag support lower plate 114 is located above the horizontal support plate 113 and fixed between the two vertical support plates 115; a gap is left between the bag support lower plate 114 and the horizontal support plate 113 to facilitate the insertion of empty packaging bags; the bag filling flap 111 is hinged to the front end top of the left and right horizontal support plates 113 through the flap rotating shaft 112, and the flap rotating shaft 112 is arranged along the left and right directions.

[0028] The bag-supporting lower plate 114 is fixed, and the bag-supporting upper plate 116 is moved up and down by the bag-supporting cylinder 1111 to support and loosen the packaging bag. Figure 2 As shown, the bag-supporting cylinder 1111 is fixed vertically downward in the middle position of the cylinder support plate 118, and the piston rod of the bag-supporting cylinder 1111 is fixedly connected to the middle position of the rear end top of the bag-supporting upper plate 116; the rear end top of the bag-supporting upper plate 116 is also fixedly provided with two bag-supporting circular optical axes 119 symmetrically about the bag-supporting cylinder 1111, and the cylinder support plate 118 is also correspondingly provided with two left and right bag-supporting circular flange linear bearings 1110 for the two bag-supporting circular optical axes 119 to pass through. The bag-supporting circular optical axis 119 and the bag-supporting circular flange linear bearing 1110 are used in combination to play a role in guiding the upward and downward lifting.

[0029] like Figure 2 As shown, a welding cylinder 117 with three top center openings is welded on the top of the rear end of the bag support upper plate 116, and a countersunk hole is opened on the side wall of the welding cylinder 117. The ends of the two bag support circular optical axes 119 and the piston rod of the bag support cylinder 1111 are respectively inserted into the center holes of the corresponding welding cylinders 117 and fastened by screws.

[0030] The forward extension length of the lower bag-supporting plate 114 is greater than the forward extension length of the upper bag-supporting plate 116, and the forward extension length of the transverse support plate 113 is greater than the forward extension length of the lower bag-supporting plate 114; when the bagging flap 111 is placed flat on the two transverse support plates 113, the upper surface of the bagging flap 111 and the upper surface of the lower bag-supporting plate 114 are on the same horizontal plane to ensure smooth feeding into the bag.

[0031] like Figure 3 As shown, the moving mechanism includes a lower ball screw assembly 122 fixed on a support platform along the left-right direction and driven by a servo motor, two lower linear guide rails 123 fixed on the support platform along the left-right direction and respectively located on the front and rear sides of the ball screw assembly 122, a lower movable tray 124 fixed on the sliders of the two lower linear guide rails 123 and the nut seat of the lower ball screw assembly 122, an upper ball screw assembly 126 fixed on the lower movable tray 124 along the front-back direction and driven by a servo motor, two upper linear guide rails 125 fixed on the lower movable tray 124 along the front-back direction and respectively located on the left and right sides of the upper ball screw assembly 126, and an upper movable tray 1215 fixed on the sliders of the two upper linear guide rails 125 and the nut seat of the upper ball screw assembly 126.

[0032] The lower ball screw assembly 122 drives the lower movable tray 124 to move left and right along the lower linear guide rail 123 on the support platform; there are three grooves at the bottom of the lower movable tray 124, and the sliders of the two lower linear guide rails 123 and the nut seats of the lower ball screw assembly 122 are respectively placed in the corresponding grooves and fixedly connected to the lower movable tray 124 by screws; the upper ball screw assembly 126 drives the upper movable tray 1215 to move forward and backward along the upper linear guide rail 125 on the lower movable tray 124.

[0033] The lower ball screw assembly 122 and the upper ball screw assembly 126 have the same structure. Figure 4As shown, the lower ball screw assembly 122 includes a lower servo motor 1221, a coupling 1222, a fixed block 1223, a nut 1224, a nut seat 1225, a screw rod 1226 and a support block 1227. The fixed block 1223 and the support block 1227 are respectively fixed to the left and right ends of the support platform along the left and right directions, the lower servo motor 1221 is fixed to the outside of the fixed block 1223, the coupling 1222 is arranged on the fixed block 1223, the rotating shaft of the lower servo motor 1221 is connected to one end of the screw rod 1226 through the coupling 1222, the other end of the screw rod 1226 is arranged on the support block 1227, and the nut seat 1225 is arranged on the screw rod 1226 through the nut 1224.

[0034] like Figure 3 As shown, the rear end of the upper movable material tray 1215 is fixedly provided with a push cylinder fixing plate 1210 extending upward, and the push cylinder 129 is fixedly provided in the middle position of the push cylinder fixing plate 1210 along the front-back direction, and the piston rod of the push cylinder 129 is fixedly connected with the middle of the rear end of the push baffle 1212; the rear end of the push baffle 1212 is fixedly provided with two push circular optical axes 127 symmetrically about the push cylinder 129, and the push circular optical axes 127 are arranged along the front-back direction, and the push cylinder fixing plate 1210 is also correspondingly provided with two left and right push circular flange linear bearings 128 for the two push circular optical axes 127 to pass through. The push circular optical axis 127 and the push circular flange linear bearing 128 are used in conjunction with each other to play a guiding role.

[0035] An adjustment block 1211 is also fixedly arranged between the upper movable material tray 1215 and the pushing cylinder fixed plate 1210. The distance between the upper movable material tray 1215 and the pushing cylinder fixed plate 1210 can be adjusted by using adjustment blocks 1211 of different specifications.

[0036] The upper surface of the upper movable tray 1215 is fixed with a wear-resistant plate 1214 through two left and right pressure strips 1213. Both the pressure strips 1213 and the wear-resistant plate 1214 are made of stainless steel. The wear-resistant plate 1214 prevents the sleeve from directly contacting the upper movable tray 1215, preventing the cutting fluid on the sleeve from corroding it. At the same time, the pressure strip 1213 also acts as a barrier to prevent the sleeve from falling during the pushing process. When the wear-resistant plate 1214 is provided on the upper movable tray 1215, the upper surface of the wear-resistant plate 1214 is on the same horizontal plane as the upper surface of the bag support lower plate 114.

[0037] The support platform is fixedly arranged on the power distribution cabinet 121, or the support platform is the housing of the power distribution cabinet 121, such as Figure 5As shown. The power distribution cabinet 121 is used to provide a stable power supply for the bag-supporting cylinder 1111, the two servo motors in the moving mechanism, and the push cylinder 129, etc., to ensure that these actuators can operate normally. A circuit protection device is arranged inside the power distribution cabinet 121. When an abnormal situation such as overload, short circuit or leakage occurs in the circuit, the circuit can be cut off in time to protect the safety of the equipment and operators. Some electrical components of the control mechanism, such as relays and contactors, are also arranged inside the power distribution cabinet 121. By controlling the on and off of these electrical components, precise control of the operation of the bag-supporting cylinder 1111, the servo motor and the push cylinder 129 is achieved, such as controlling the extension and retraction speed of the cylinder, the moving direction and speed of the moving mechanism, etc., to ensure that the entire automatic bagging machine operates stably and efficiently according to the preset procedures and parameters.

[0038] like Figure 5 As shown, the control mechanism 13 includes a PLC controller 132 and a bag-opening cylinder control button 131 fixedly arranged on one side of the power distribution cabinet 121. The bag-opening cylinder control button 131 is used to control the lifting and lowering of the bag-opening cylinder 1111, and the PLC controller 132 is used to control the moving direction and distance of the upper and lower material trays, and includes a display screen and a button switch.

[0039] The specific working process of the present invention is as follows: Figure 6 As shown, the automatic bagging machine 1 is the last device of the entire sleeve automatic production line. The sleeve detection device 2 in front of it is used to inspect the sleeve and laser mark it. Then the truss robot device 3 grabs the sleeve through the robot and places it on the upper movable material tray 1215 of the automatic bagging machine 1. The lower ball screw assembly 122 and the upper ball screw assembly 126 are controlled by PLC to drive the upper movable material tray 1215 to move left and right and forward and backward, so that the sleeves are automatically discharged in sequence on the upper movable material tray 1215. When the number of sleeves on the moving material tray 1215 reaches the set number, the upper moving material tray 1215 and the bag support lower plate 114 are connected through the PLC control, and then the push cylinder 129 first pushes the sleeve on the upper moving material tray 1215 into the packaging bag to complete the bagging, and then pushes the packaging bag and the sleeve onto the bagging flap 111. The bagging flap 111 drives the packaging bag to flip toward the front and lower part of the power distribution cabinet 121. The worker takes the standing packaging bag from the bagging flap 111 and seals it with a baler. After the push cylinder 129 returns to its position, the bag support cylinder 1111 pushes down the bag support upper plate 116, and then the worker inserts a new packaging bag and presses the bag support cylinder control button 131. The bag support upper plate 116 moves up and opens the bag mouth of the packaging bag. The automatic bagging machine 1 continues to run automatically to complete the next bagging process.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
