[0036] The following is a combination of the embodiments of the present invention Figure 1-14 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example

[0038] like Figures 1 to 4 As shown, this embodiment discloses a new type of bagged object loading head assembly, including a head frame, on which are installed a feeding area 8 for placing bagged objects, a material shifting mechanism 1 for shifting the bagged objects, a feeding mechanism for receiving the bagged objects A moved by the material shifting mechanism, and an electric stacking gripper for grabbing the bagged objects, the electric stacking gripper is equipped with a multi-stage manipulator mechanism that can move up and down, and the multi-stage manipulator mechanism is equipped with an electric stacking gripper; the feeding mechanism is divided into a left feeding mechanism 2 and a right feeding mechanism 3.

[0039] The described material pushing mechanism 1 includes a middle support plate for placing bagged objects (i.e., the above-mentioned feeding area), a transmission mechanism, a hanging bracket 15, a guide rail bracket 16, a moving bracket 9 that moves on the guide rail bracket 16, and a scraper 17 installed below the moving bracket. Both ends of the guide rail bracket 16 are installed on the hanging bracket 15, and the upper end of the hanging bracket 15 is fixedly connected to the head frame. The transmission mechanism is installed on one side of the hanging bracket. The operation of the transmission mechanism drives the moving bracket to move on the guide rail bracket to push the bagged objects onto the feeding mechanism.

[0040] The transmission mechanism includes a reducer unit 4, a driving gear 5, a synchronous belt 6, and a driven gear. The output end of the reducer unit is connected to the driving gear 5 to drive it to rotate. The driven gear is located on the other side, and the synchronous belt 6 is sleeved on the driving gear and the driven gear. The above-mentioned moving bracket is provided with side roller bearings 10 on both sides of the guide rail bracket, upper roller bearings 12 and lower roller bearings 11 on the upper and lower sides of the guide rail bracket, and a mounting plate 7 installed on the synchronous belt, forming an operating mechanism on the outside of the moving bracket.

[0041] Reference Figures 9-12 The above-mentioned feeding mechanism includes a left feeding machine frame 116a, a right feeding machine frame 115a, and a conveying mechanism. The conveying mechanism is installed between the left feeding machine frame and the right feeding machine frame. The conveying mechanism includes a motor 100a, a driving shaft 101a and a driven shaft 109a connected to the output end of the motor. The driving shaft 101a and the driven shaft 109a are respectively installed on the left feeding machine frame 116a and the right feeding machine frame 115a. The driving shaft 101a and the driven shaft 109a are both installed with sprockets 102a, and a chain 117a is fitted on the sprockets 102a. A chain plate 103a is installed on the chain 117a, and a chain knot 120a is installed between the chain plate 103a and the chain 103a. The chain plate 103a is locked on the chain knot 120a through an upper fastener 118a, and the chain knot of the chain 117a is locked on the chain 103a through a lower fastener 119a. The upper fastener 118a and the lower fastener 119a adopt screws. The cross-section of the chain plate is in a triangular structure. The double fixation of the chain plate is realized through the triangular cross-section chain plate and the double fastener structure, enhancing the stability of the chain plate during the conveying process; the triangular structure can effectively convey the box objects and reduce the sliding of the materials at the same time. The chain plates 103a are installed on the chain at intervals.

[0042] The chain plate 103a has a front vertical unit 1131a and a slope unit 1132a. The upper end of the slope unit is at the top of the vertical unit, forming an inclined structure as an anti-slip structure.

[0043] The upper end surface of the chain 117a is covered with mounting holes 1031a. This solution adopts a multiple-hole opening method, aiming to make the installation of the chain plate more convenient, meet the installation requirements of different spacings, and improve the versatility.

[0044] The link plate includes a tail link plate 109a, on which a material pushing mechanism is installed. The material pushing mechanism includes a push plate 105a and a push plate mounting seat 107a for mounting the push plate.

[0045] Below the push plate mounting seat 107a, eccentric wheels 110a are arranged side by side. The eccentric wheels 110a are installed on the push plate mounting seat 107a by nut screws. A feeding cross plate 108a is also installed between the left feeding machine frame and the right feeding machine frame. A sliding plate 111a is installed on the end face of the feeding cross plate. Both sides of the sliding plate are slidably matched with the eccentric wheels. A convex column 112a is installed above the push plate mounting seat. A long hole 1061 is formed in the tail link plate. The convex column extends into the long hole. The tail link plate and the push plate form an end positioning mechanism to accurately push the material to the designated station and improve the reliability of conveying.

[0046] Among them, referring to Figures 5-8 , the electric palletizing gripper device includes a palletizing frame 100, a driving component, a first connecting rod 118, a second connecting rod 113, a first flap 108, and a second flap 107. The palletizing frame has a left palletizing frame 103, a right palletizing frame 105, and an upper palletizing frame 104. The left palletizing frame 103, the right palletizing frame 105, and the upper palletizing frame 104 enclose a storage space A. One side of the first flap 108 is connected and installed on the left palletizing frame through a hinge 109. One side of the second flap is connected and installed on the right palletizing frame through a hinge 110. The purpose of the connection is to enable the first flap 108 and the second flap 107 to rotate around the left palletizing frame 103 and the right palletizing frame 105 respectively, that is, the first flap 108 can move on the left palletizing frame 103, and the second flap 107 can move on the right palletizing frame 105. The outer side of the first flap faces the outer side of the second flap, that is, the outer sides of the two face each other. The first connecting rod 118 is connected to the first flap through a shaft rod 117. The lower section 1181 of the first connecting rod 118 is movably connected to the shaft rod 117. The shaft rod 117 is fixedly connected to the first flap. The second connecting rod 113 is connected to the second flap through a shaft rod 114. The lower section 1132 of the second connecting rod 113 is movably connected to the shaft rod 114. The shaft rod 114 is fixedly connected to the first flap.

[0047] In this solution, the first flap and the second flap are preferably symmetrically designed. The other ends of the first connecting rod and the second connecting rod are connected to the driving component, and the driving component rotates to drive the first connecting rod and the second connecting rod to work.

[0048] The opening and closing actions of the first flap and the second flap are synchronously controlled by a driving component to achieve the rapid clamping and release of goods of different sizes and shapes (such as boxes, bagged goods, etc.), meeting the high-efficiency requirements of the automated palletizing scenario. The first flap is fixed to the inner side of the left palletizing frame by a hinge, and the second flap is fixed to the inner side of the right palletizing frame by a hinge. The outer sides of the two are arranged opposite to each other, and the initial state is closed (clamping position).

[0049] A number of first ridges 1081 are machined on the first flap 108. Preferably, a number of second ridges 1071 are machined on the second flap 107. Preferably, both the first ridges 1081 and the second ridges 1071 are triangular. The purpose is to make the grabbed goods stable. The triangular ridges (first ridges, second ridges) on the flap increase the friction force on the contact surface with the goods, preventing the goods from sliding or falling off during handling.

[0050] The driving component includes a motor 119 and a gearbox assembly. In this solution, a motor is used instead of a cylinder to solve the problem of the limitation of cylinder use in some cold regions. The motor is installed at the inner end of the palletizing frame, and the output shaft of the motor is connected to the input end of the gearbox assembly. The gearbox assembly has a first output end 1202 and a second output end 1201. The first output end 1202 and the second output end 1201 are respectively connected with a first rotating arm 115 and a second rotating arm 111. The outer end 116 of the first rotating arm is connected to the above-mentioned first connecting rod 118, and the outer end 112 of the second rotating arm is connected to the above-mentioned second connecting rod.

[0051] This solution uses the input of the motor as the power source, and through the gearbox assembly, two output ends are branched out to drive the swinging of the first rotating arm 115 and the second rotating arm 111 to achieve the opening and closing actions of the first flap and the second flap. It should be noted that the operation between the motor and the gear is prior art and will not be described in detail.

[0052] Preferably, a motor protection cover 106 is also installed inside the palletizing frame, and the motor protection cover is machined with a guiding end face. It serves to protect the motor.

[0053] Among them, the bearing adjustment seat assembly includes a feeder frame 100b and a conveying mechanism installed on the feeder frame. The conveying mechanism includes a motor 110b, a driving shaft and a driven shaft 104b connected to the output end of the motor. The driving shaft and the driven shaft are respectively installed on the left feeder frame and the right feeder frame. Sprockets 102b and a chain 101b are installed on the driving shaft and the driven shaft.

[0054] On both sides of the passive shaft are used as passive shaft mounting sections 1041b. An adjustment mechanism is mounted on the passive shaft mounting section. The adjustment mechanism includes a slide bearing adjustment seat 105b, a bearing adjustment slide seat 106b that slides on the slide bearing adjustment seat, and a locking rod 104b for driving the bearing adjustment slide seat to move back and forth. The locking rod is a screw. The bearing adjustment seat 105b is mounted on the feeder frame 100b. Specifically, the adjustment seat is mounted on the feeder frame through fasteners 1051b, and the fasteners are screws or screws, etc. The bearing adjustment slide seat 106b is mounted on the upper slide bearing adjustment seat 105b, and the passive shaft mounting section 1041b is mounted on the bearing adjustment slide seat 106b. One end of the locking rod 109b is connected to the bearing adjustment slide seat 106b, and the other end is mounted on the slide bearing adjustment seat through a fastener 110b. The fastener 110b is fixed in cooperation with the locking rod 109b by a nut. The slide bearing adjustment seat serves as a bearing and guiding base, and the slide bearing adjustment seat 105 provides a structural constraint for the bearing adjustment slide seat to guide the moving direction of the slide seat; the bearing adjustment slide seat bears the passive shaft mounting section and realizes displacement adjustment through sliding. By screwing the fastener locking rod, the slide seat is pushed to move along the slide way, realizing the "adjustment and locking" operation. Preferably, the locking rod is a screw. The thread pair of the screw can convert the rotational motion into a linear displacement to achieve precise push-pull adjustment.

[0055] The described slide bearing adjustment seat is machined with an upper slide way and a lower slide way 1052b. The bearing adjustment slide seat has an upper slide block adapted to the upper slide way and a lower slide block 1061b adapted to the lower slide way. Through the nested fit of the upper and lower slide ways and the slide blocks (upper slide way / lower slide way and upper slide block / lower slide block), the linear guiding function of the bearing adjustment slide seat is realized. Combined with the screw locking structure, the passive shaft mounting section can be calibrated, effectively ensuring the belt tension and the axis parallelism. Through the nested fit of the upper and lower slide ways and the slide blocks, the slide seat is constrained to move only in a straight line to prevent skew during adjustment;

[0056] The bearing adjustment slide seat 106b is machined with a threaded mounting port 1062b. One end of the locking rod is locked in the threaded mounting port 1062b through a nut 108b. A slide bearing adjustment seat mounting threaded hole 1063b adapted to the locking rod is opened on the slide bearing adjustment seat 105. The slide adjustment seat is provided with a threaded mounting port 1063b, and the locking rod is fixed through a nut 110b. This structure is convenient for operation and can facilitate installation and adjustment of loosening after operation.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
