Technical Field

[0001] The present application relates to the technical field of packaging machine manufacturing, and in particular to a dual-mode material arrangement device for a packaging machine. Background Art

[0002] In the packaging machinery industry, with the continuous improvement of the level of automated production, efficient and accurate arrangement of materials has become one of the key factors in improving the overall efficiency of the production line; the traditional manual arrangement method is not only time-consuming and labor-intensive, but also prone to errors, and cannot meet the high-paced requirements of modern industrial production; therefore, various automated material arrangement equipment has emerged, which can significantly improve production efficiency, reduce labor costs, and ensure the consistency of product quality; in addition, with the rapid development of the logistics industry, especially the popularization of e-commerce, the demand for packaging machinery is growing, which has promoted the pace of technological innovation in this field, making material arrangement technology develop in a more diversified, flexible and efficient direction.

[0003] At present, in the field of material arrangement technology, common solutions include the use of cylinder-driven pushers, servo motor-controlled rotary dials, and linear motor-driven push arms. These methods are mainly used to arrange scattered items in a certain order to facilitate subsequent packaging or packaging operations.

[0004] However, the above-mentioned traditional material arrangement method has certain limitations. In the packaging of sheet materials, it is divided into small-piece packaging and trayless packaging. Small-piece packaging is to package the sheet materials in a horizontally stacked manner, and trayless packaging is to package the sheet materials in a vertically stacked manner. These two packaging methods are particularly common in the snack packaging industry. In order to meet production needs, manufacturers often need to purchase two sets of packaging machines to respectively perform small-piece packaging and trayless packaging on the materials, which greatly increases the processing cost. Therefore, in order to reduce the production cost of material packaging and improve the packaging efficiency of materials, a packaging machine that can realize two material arrangement modes is urgently needed. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the present application provides a dual-mode material arrangement device for a packaging machine, which can perform both small-piece packaging and trayless packaging, so as to reduce the production cost of material packaging and improve the packaging efficiency of materials.

[0013] By adopting the above technical solution, the design of the first guide rail enables the first fork to be driven differently at different stages. First, the first oblique rising part overcomes gravity to raise the angle of the first fork, then the horizontal flat part is used to stabilize the position and angle of the fork, and finally the second oblique rising part is used to further adjust the posture of the fork to ensure that it can be smoothly inserted into the second conveyor belt in a vertical state, avoiding excessive downward pressure, which will damage the materials when the stacked materials are pushed together, thereby effectively realizing the horizontal orderly arrangement of the sheet materials.

[0015] By adopting the above technical solution, efficient and accurate arrangement of sheet materials is achieved. Specifically, the second toggle mechanism uses the effect of the elastic member to enable the second fork to smoothly enter the second conveyor belt in an oblique state, and transform into a vertical state after a preset distance, to ensure that the materials can be arranged in an oblique state first during the transmission process, and then arranged in a vertical state under the flipping action of the second fork after a preset distance; and the design of the third toggle mechanism, especially the vertical insertion function of the third fork under the joint action of gravity and the guide rail, can support the rear of the materials arranged in a vertical state to prevent the materials from collapsing, thereby improving the stability and reliability of the entire arrangement process.

[0017] By adopting the above technical scheme, the staggered arrangement and timing control of the third fork and the second fork are realized, ensuring that sheet materials of different sizes and shapes can be accurately and efficiently arranged in an orderly longitudinal manner on the second conveyor belt. Specifically, the arc-shaped point head and oblique head design of the second guide rail enable the second fork to separate the materials on the first conveyor belt for a short time, so that a predetermined number of materials enter the second conveyor belt in sections, so as to ensure the consistency and stability of the material arrangement; at the same time, the oblique climbing part and horizontal holding part design of the third guide rail further ensure that the third fork can be inserted into the designated position in a timely and stable manner, thereby collaboratively completing the material arrangement operation under complex working conditions, thereby improving the applicability and working efficiency of the equipment.

The intermediate seat 44 is detachably connected to the slide 4, and the seat plate is detachably connected to the intermediate seat 44. When the fork mechanism is disassembled and assembled, the intermediate seat 44 does not need to be disassembled and assembled. If the intermediate seat 44 is damaged, the intermediate seat 44 can be replaced, thereby reducing the frequency of direct disassembly and assembly on the slide 4.

[0035] The device uses magnetic levitation technology and mechanical structure design to effectively improve the flexibility and precision of material arrangement, and can realize horizontal and vertical stacking arrangements of materials, ensuring packaging efficiency and quality, and reducing factory production costs.

[0036] refer to Figures 1 to 3 When the materials need to be stacked horizontally, a toggle mechanism is installed on the slide 4 as a first toggle mechanism 421 , and a guide rail is fixed on the mounting seat 5 as a first guide rail 61 .

[0037] Specifically, refer to Figures 5 and 6The first shifting mechanism 421 includes a first seat plate 4211 and a first shift fork 4212 rotatably connected to the first seat plate 4211; an upper positioning pin 4214 and a lower positioning pin 4215 are provided on the first seat plate 4211 to limit the rotation angle of the first shift fork 4212; a first transmission pin 4213 is provided on the first shift fork 4212; under the action of gravity, the first shift fork 4212 is arranged obliquely backward between the upper positioning pin 4214 and the lower positioning pin 4215, which is opposite to the material conveying direction; the first guide rail 61 is used to guide the movement of the first transmission pin 4213, drive the first shift fork 4212 to rotate in the material conveying direction, and enter the second conveyor belt 21 in a vertical state.

[0038] refer to Figure 5 The first guide rail 61 includes a first oblique rising portion 611, a horizontal flat portion 612, a second oblique rising portion 613 and a horizontal pushing portion 614 in sequence along the travel direction of the first transmission pin 4213; the first oblique rising portion 611, the horizontal flat portion 612 and the second oblique rising portion 613 are all located below the input end of the second conveyor belt 21. This design enables the first fork 4212 to be driven differently at different stages. First, the first oblique rising portion 611 is used to overcome gravity to lift the angle of the first fork 4212, and then the horizontal flat portion 612 is used to stabilize the position and angle of the fork. Finally, the second oblique rising portion 613 is used to further adjust the posture of the fork to ensure that it can be smoothly inserted into the second conveyor belt 21 in a vertical state, avoiding excessive downward pressure, which causes damage to the materials when the stacked materials are pushed together, thereby effectively realizing the horizontal orderly arrangement of the sheet materials.

[0039] refer to Figure 3 and Figure 5 During operation, the slide 4 moves on the track 32 with the help of the mover unit 43 under the power provided by the stator unit 311. When passing through the output end of the first conveyor belt 11 and entering the second conveyor belt 21, it passes through the first oblique rising portion 611, the horizontal gentle portion 612, the second oblique rising portion 613 and the horizontal pushing portion 614 on the first guide rail 61 in sequence, so that the first fork 4212 is slowly deflected in stages. When passing through the first oblique rising portion 611 and entering the horizontal gentle portion 612, the first fork 4212 is deflected at a small angle and protrudes from the second conveyor belt 21, so that the material can be blocked and the speed of the material behind the first fork 4212 can be controlled, so that the material on the first conveyor belt 11 can be horizontally stacked on the material on the second conveyor belt 21. When passing through the second oblique rising portion 613 and entering the horizontal pushing portion 614, the slide 4 speeds up, catches up with the material in front, pushes the horizontally stacked material together, and transports the material to the next process.

[0040] refer to Figure 7-8When the vertical stacking arrangement of the materials is to be realized, the toggle mechanisms installed on the slide 4 are the second toggle mechanism 422 and the third toggle mechanism 423, and the guide rails installed on the mounting seat 5 are the second guide rail 62 and the third guide rail 63, wherein the second toggle mechanism 422 and the third toggle mechanism 423 are arranged alternately.

[0041] Specifically, refer to Figures 8 and 9 The second shifting mechanism 422 includes a second seat plate 4221 and a second fork 4222 rotatably connected to the second seat plate 4221; an upper positioning block 4224 is provided on the second seat plate 4221, and a second transmission pin 4223 is provided on the second fork 4222; an elastic member is provided between the second seat plate 4221 and the second fork 4222, and the elastic member drives the second fork 4222 to abut against the upper positioning block 4224 forwardly and obliquely. The elastic member can be a torsion spring installed between the second seat plate 4221 and the second fork 4222; the second guide rail 62 is used to guide the movement of the second transmission pin 4223 to drive the second fork 4222 to first enter the second conveyor belt 21 in a forward oblique state, and then enter the second conveyor belt 21 in a vertical state after passing a set distance.

[0042] refer to Figures 10-12 The second guide rail 62 includes an arc-shaped point head 621 and an oblique head portion 622 in sequence along the travel direction of the second transmission pin 4223. The arc-shaped point head portion 621 is located below the output end of the first conveyor belt 11, and the oblique head portion 622 is located below the middle of the second conveyor belt 21.

[0043] refer to Figures 13 and 14 The third shift mechanism 423 includes a third seat plate 4231 and a third fork 4232 slidably connected to the third seat plate 4231; the third fork 4232 is provided with a third transmission pin 4233, the third seat plate 4231 is provided with an open slide groove 4234, and the third fork 4232 is slidably connected in the open slide groove 4234 along the vertical direction; under the action of gravity, the third fork 4232 is at the bottom end of the open slide groove 4234; the third guide rail 63 is used to guide the movement of the third transmission pin 4233 at the set position to drive the third fork 4232 to be inserted into the second conveyor belt 21 in a vertical state.

[0044] refer to Fig.14 and Figure 8 The third guide rail 63 includes an oblique lifting portion 631 and a horizontal supporting portion 632 in sequence along the travel direction of the third transmission pin 4233 . The oblique lifting portion 631 is located below the middle of the second conveyor belt 21 and is placed at the front end of the oblique raising portion 622 .

[0045] refer to Figure 8 , Fig.11 and Fig.14During operation, the slide 4 moves on the track 32 with the help of the mover unit 43 under the power provided by the stator unit 311. When passing the output end of the first conveyor belt 11, the second fork 4222 passes the arc-shaped point head 621 and deflects and lifts at a small angle to protrude the first conveyor belt 11 and block the materials on the first conveyor belt 11. The speed of the materials behind the second fork 4222 is controlled on the first conveyor belt 11, so that a set amount of materials on the first conveyor belt 11 can fall on the second conveyor belt 21 and be stacked obliquely on the previous second fork 4222 in sequence. The second fork 4222 obliquely supports the materials and transmits them at the same speed as the second conveyor belt 21. The third fork 4232 follows behind the second fork 4222 and keeps the same speed with the second fork 4222. At a set distance, when the third fork 4232 passes through the oblique lifting portion 631 and enters the horizontal supporting portion 632, the third fork 4232 moves upward to protrude the second conveyor belt 21. After the third fork 4232 protrudes from the second conveyor belt 21, the second fork 4222 that obliquely supports the material enters the oblique raising portion 622. The second fork 4222 is deflected under the guidance of the oblique raising portion 622, and is transmitted at the same speed as the second conveyor belt 21 in a vertical posture.
