[0001] The invention relates to the technical field of packaging material palletizing, and in particular to a convenient palletizing device for packaging materials. Background Art

[0002] In the modern production and logistics system, packaging materials are the key link in product protection, transportation and storage. Their processing efficiency and degree of automation directly affect the company's operating costs and market competitiveness. In order to facilitate the transportation and storage of packaging materials, packaging materials need to be palletized.

[0003] The Chinese patent with publication number CN110562752A discloses an automatic palletizing device for packaging materials, which includes a mounting frame, a rotating shifting mechanism for shifting and stacking packaging materials, and a conveying mechanism for conveying packaging materials. The rotating shifting mechanism and the conveying mechanism are mounted on the mounting frame, and a controller for controlling the operation of the rotating shifting mechanism and the conveying mechanism is provided on the mounting frame. The mounting frame includes a vertical plate, a conveying platform, and an output platform. The conveying platform and the output platform are arranged horizontally and perpendicular to each other. The conveying end is close to the conveying start end of the output platform, the vertical plate is close to the conveying end and the conveying start end of the output platform, the conveying direction of the conveying platform is perpendicular to the plate surface of the vertical plate, and the rotating shift mechanism is installed between the conveying end and the conveying start end of the output platform. Although the above patent can stack the packaging materials, due to the clamping area of ​​the clamping block, it can only be clamped and fixed by the side of the packaging material, and the packaging material cannot be supported to complete the transportation and palletizing. If the clamping effect is improved by increasing the holding force, the outer surface of the packaging material is easily squeezed and deformed to cause damage, and the safety is low.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a convenient palletizing device for packaging materials is proposed, which can clamp the sides of the packaging materials and simultaneously support the bottom to complete palletizing, making the transportation palletizing more stable and safer. Summary of the invention

Two guide tubes 18 are fixedly connected on the right sides of the front and rear sides of the installation frame 2. The positioning frames 181 are slidably connected to the inner sides of the four guide tubes 18. When the positioning frames 181 move to contact the packaging material, the positioning frames 181 can realize the centering of the packaging material. The ends of the front and rear positioning frames 181 that are close to each other are respectively connected to the inner sides of the front and rear guide tubes 18 with connecting springs 187. The upper part of the positioning frame 181 is horizontally slidably connected with a positioning rod 182. When the positioning rod 182 moves horizontally, the positioning rod 182 can realize the centering of the packaging material. A reset spring 1821 is connected between the positioning rod 182 and the inner side of the positioning frame 181. The elastic force of the reset spring 1821 is greater than the elastic force of the connecting spring 187. A pulling assembly is provided between the mounting frame 2 and the guide tube 18. When the pulling assembly is in operation, the pulling assembly can realize the movement of the pulling positioning frame 181; the pulling assembly includes a first wire tube 183, an electric shaft 184, a double-groove winding wheel 185, a pulling wire 186 and a second wire tube 1861. The sides of the front and rear positioning frames 181 that are away from each other are fixedly connected with the second wire tube 1861, and the sides of the front and rear positioning frames 181 that are close to each other are fixedly connected with the first wire tube 183. The right side of the mounting frame 2 is rotatably penetrated by the electric shaft 184, and the double-groove winding wheel 185 is symmetrically fixedly mounted on the electric shaft 184. Two pulling wires 186 are wound around the double-groove winding wheel 185. The tail ends of the four pulling wires 186 respectively pass through the first wire tube 183 and the second wire tube 1861 and are fixedly connected to the four positioning rods 182. When the pulling wire 186 is wound, the pulling wire 186 can realize the movement of the positioning rod 182.

[0034] First, move the frame 1 so that the conveying component 3 corresponds to the assembly line, then start the conveying component 3 to rotate forward, and move the carrier plate to the bottom of the frame 1. When the packaging material on the assembly line moves onto the conveying component 3, the conveying component 3 rotates forward to drive the packaging material to move to the right. When the packaging material moves to the right between the front and rear positioning frames 181, close the conveying component 3, start the electric shaft 184 to drive the double-groove winding wheel 185 to reverse, and the double-groove winding wheel 185 reverses to reel the pull wire 186. The reeled pull wire 186 passes through the first wire tube 183 and the second wire tube 1861 and first drives the front and rear positioning rods 182 to move in a direction close to each other. The positioning rods 182 drive the front and rear positioning frames 181 to move in a direction close to each other, and the connecting spring 187 is compressed. The front and rear positioning frames 181 are in contact with the front and rear sides of the packaging material, and the front and rear positioning frames 181 position the packaging material. The front and rear positioning frames 181 stop moving, and then the pull wire 186 continues to be wound up, and the pull wire 186 drives the left and right positioning rods 182 to move in a direction close to each other, and the reset spring 1821 is compressed, and the left and right positioning rods 182 move in a direction close to each other and contact the left and right sides of the packaging material, and the positioning rods 182 center the packaging material. Under the action of the positioning rods 182 and the positioning frames 181, the packaging material can be positioned in the center, which can prevent the position of the packaging material from being offset and affecting the clamping of the clamping block 9, thereby ensuring that the packaging material is accurately clamped, and then the electric shaft 184 is started to drive the double-groove winding wheel 18 5 is rotated forward to reset, the double-groove winding wheel 185 rotates forward to loosen the pulling wire 186, due to the action of the reset spring 1821, the left and right positioning rods 182 move away from each other to reset, and the positioning rods 182 are out of contact with the packaging material, and then due to the action of the connecting spring 187, the front and rear positioning frames 181 move away from each other to reset, and the positioning frames 181 are reset and out of contact with the packaging material, and then the electric telescopic frame 5 is started to extend to drive the stepper motor 6 to move to the left, and the stepper motor 6 moves to the left to drive the lateral movement module 7 to move to the left, and the lateral movement module 7 drives the frame 8 to move to the left, and the frame 8 drives the clamping block 9 to move to the left to just above the packaging material, and the electric telescopic frame 5 is closed, and the lifting assembly 4 is started to drive the stepper motor 6 to move downward through the electric telescopic frame 5 The stepper motor 6 drives the frame 8 to move downward through the transverse movement module 7, and the frame 8 drives the front and rear clamping blocks 9 to move downward and are located at the front and rear sides of the packaging material. When the frame 8 moves downward and contacts the packaging material, the lifting component 4 is closed, and the electric screw 10 is started to rotate forward to drive the front and rear clamping blocks 9 to move and contact the packaging material. The front and rear clamping blocks 9 clamp the packaging material, and the electric screw 10 is closed. The air pump 13 is started to discharge the air into the three-way pipe 14. The air in the three-way pipe 14 is first discharged into the telescopic airbag 15 near the clamping block 9. Due to the limitation of the arc-shaped limiting plate 12 on the top of the hinge block assembly 11, the telescopic airbag 15 near the clamping block 9 expands and drives the hinge block assembly 11 to swing downward, and the hinge block assembly 11 swings downward and contacts the packaging material.The hinged block of the hinged block assembly 11 in contact with the packaging material stops swinging, and then the air is continuously discharged into the air pressure valve 16. When the pressure in the air pressure valve 16 reaches the maximum value, the air pressure valve 16 opens, and the air flows into the infiltrated telescopic airbag 15, so that the remaining telescopic airbag 15 expands and drives the hinged blocks of the hinged block assembly 11 that are not in contact with the packaging material to continue to swing, so that the hinged blocks of the hinged block assembly 11 are continuously in contact with the packaging material, and the hinged blocks of some hinged block assemblies 11 are in contact with the bottom of the packaging material. When the hinged block assembly 11 is completely in contact with the packaging material, the air pump 13 is turned off, the air stops flowing, and the hinged block assembly 11 is in contact with the packaging material. The block assembly 11 supports the bottom of the packaging material, and the lifting assembly 4 is started again to drive the stepper motor 6 to move upward and reset through the electric telescopic frame 5, so that the clamping block 9 and the hinged block assembly 11 drive the packaging material to move upward and disengage from the conveying assembly 3, and then the electric telescopic frame 5 is shortened and drives the stepper motor 6 to move right and reset, so that the clamping block 9 and the hinged block assembly 11 drive the packaging material to move right for transportation and stacking. Since the hinged block assembly 11 supports the bottom of the packaging material, the packaging material can be transported and stacked more stably, thereby improving the safety of packaging material stacking, and the electric telescopic frame 5 is closed and started The dynamic lifting assembly 4 drives the stepping motor 6 to move downward and reset through the electric telescopic frame 5, so that the clamping block 9 and the hinge block assembly 11 drive the packaging material to move downward and close to the carrier plate, the lifting assembly 4 is closed, the cylinder 19 is started to exhaust air, and the air in the telescopic airbag 15 is extracted through the three-way pipe 14. As the air is extracted, the telescopic airbag 15 continuously contracts and drives the hinge block assembly 11 to swing upward and reset. The hinge block assembly 11 resets and disengages from the packaging material, and then the electric screw 10 is started to reverse and drive the front and rear clamping blocks 9 to move away from each other and reset. The clamping block 9 loosens the packaging material, and the packaging material After the packaging materials are dropped onto the carrier board, the stacking is completed. Then the lifting assembly 4 is started to move upward and reset through the electric telescopic frame 5, which also causes the clamping block 9 and the hinged block assembly 11 to move upward and reset. According to the above operation, the packaging materials can be clamped and transported to complete the stacking. At the same time, the position of the clamping block 9 can be adjusted through the transverse module 7, so that every two packaging materials can be stacked side by side. By starting the stepper motor 6 to drive the transverse module 7 to rotate ninety degrees, the transverse module 7 can drive the clamping block 9 to rotate ninety degrees through the frame 8. The clamping block 9 drives the packaging materials to rotate ninety degrees, so that each adjacent row of packaging materials can be stacked perpendicular to each other. When there is a proper amount of packaging materials stacked on the carrier board, the carrier board can be lifted by a forklift to transport the stacked packaging materials to the designated location.

[0035] See also Figure 8 and Fig. 9As shown, the portable palletizing device for packaging materials also includes a limiting assembly installed on the frame 1, the limiting assembly includes a cylinder 19, a positioning plate 191, a guide wheel 192 and a material limiting assembly, the lower parts of the left and right sides of the frame 1 are symmetrically fixed with cylinders 19, the ends of the telescopic rods of the four cylinders 19 are fixed with positioning plates 191, when the positioning plates 191 move and contact with the packaging materials after palletizing, the positioning plates 191 can limit the stacked packaging materials, the front and rear positioning plates 191 are evenly spaced apart from each other and vertically rotatably connected with guide wheels 192, the guide wheels 192 can realize In order to reduce the friction between the positioning plate 191 and the packaging material, a material limiting component is arranged on the positioning plate 191. When the material limiting component is in operation, the material limiting component can limit the carrier plate. The material limiting component includes a fixed cylinder 193, a U-shaped limiting plate 194 and an electric push rod 195. The four positioning plates 191 are fixedly connected to the fixed cylinder 193 on the side away from each other, and the electric push rod 195 is fixedly connected to the inner side of the fixed cylinder 193. The U-shaped limiting plate 194 is fixedly connected between the ends of the telescopic rods of the electric push rods 195 on the front and rear sides. When the U-shaped limiting plate 194 moves and contacts with the carrier plate, the U-shaped limiting plate 194 can limit the carrier plate.

[0036] When the carrier plate moves to the bottom of the frame 1, the electric push rod 195 is first started, and the telescopic rod of the electric push rod 195 is extended to drive the U-shaped limit plate 194 to move downward. When the U-shaped limit plate 194 moves downward to a position suitable for limiting the carrier plate, the electric push rod 195 is closed, and then the left and right cylinders 19 are started, and the telescopic rods of the cylinders 19 are extended to drive the left and right positioning plates 191 to move in a direction close to each other. The left and right positioning plates 191 move in a direction close to each other, driving the left and right guide wheels 192 to move in a direction close to each other. The left and right positioning plates 191 move in the direction of approaching each other, and the left and right positioning plates 191 move in the direction of approaching each other through the fixed cylinder 193, and the left and right electric push rods 195 move in the opposite direction of approaching each other. The electric push rods 195 drive the left and right U-shaped limiting plates 194 to move in the direction of approaching each other. The left and right U-shaped limiting plates 194 move in the direction of approaching each other and contact the carrying plate. The U-shaped limiting plates 194 limit the carrying plate so that the carrying plate will not move, which can prevent the carrying plate from moving and affecting the stacking of packaging materials, thereby The accuracy of packaging material stacking is improved. When the packaging material is being stacked, the packaging material contacts the positioning plate 191, and the positioning plate 191 positions the position of the packaging material so that the position of the packaging material is consistent each time. At the same time, the stacked packaging material contacts the guide wheel 192. When a proper amount of packaging material is stacked on the carrier plate, the cylinder 19 is started to drive the left and right positioning plates 191 to move and reset in the direction away from each other. The positioning plate 191 resets and drives the left and right guide wheels 192 to move and reset in the direction away from each other. The guide wheels 192 are reset and roll on the packaging material. The guide wheels 192 reduce the friction between the positioning plate 191 and the packaging material to prevent the positioning plate 191 from being too large and causing the position of the packaging material to shift and affect the stacking. At the same time, the positioning plate 191 is reset and also drives the left and right U-shaped limiting plates 194 to move and reset in the direction away from each other through the fixing cylinder 193 and the electric push rod 195. The U-shaped limiting plates 194 are reset and disengaged from the carrier plate, and the carrier plate stops being limited, and the carrier plate can be transported by a forklift. In this way, the position of the packaging materials after palletizing can be prevented from being offset, causing tipping and affecting palletizing, thereby ensuring the accuracy of the packaging material palletizing.

[0037] See also Fig.10 As shown, the portable palletizing equipment for packaging materials also includes a fixed plate 20 and a buffer airbag 21. The fixed plates 20 are fixedly connected to the lower parts of the left and right side surfaces of the frame 8, and the buffer airbags 21 are fixedly connected to the bottoms of the left and right fixed plates 20. When the buffer airbags 21 come into contact with the packaging materials, the buffer airbags 21 can provide buffering protection for the packaging materials.

[0038] When the frame 8 moves downward and drives the clamping block 9 to move downward to both sides of the packaging material, the frame 8 also drives the buffer airbag 21 to move downward through the fixed plate 20. The buffer airbag 21 moves downward and contacts the packaging material. The buffer airbag 21 protects the packaging material. In this way, the frame 8 can be prevented from being in violent contact with the packaging material, causing damage to the packaging material, thereby ensuring the integrity of the packaging material.
