Description

[0002] In the modern packaging industry, bag inserters play a vital role and are widely used in the packaging process of various products. During the working process of the bag inserter, the suction device is responsible for grabbing the bag so that it can be accurately inserted into the designated position. When the bag inserter is working, the bags are usually stored and supplied in the form of stacks. The stack heights of bags of different batches and specifications often vary. Since the table height of the bag placement of traditional bag inserters is mostly fixed, or can only be adjusted manually to a very limited extent, it is difficult for the suction device to accurately adapt to the bag stacks of different heights. As the bag inserter completes the bag insertion action, the height of each bag stack is gradually reduced. However, since the distance between the suction device and the bag is inconvenient to adjust with the working process, when the distance is too far, it is easy to have loose suction, position deviation, or even completely miss the bag during the suction process, which seriously affects the success rate of bag insertion and packaging quality.

[0014] The working principle of the present invention is that, in the actual operation of the bag inserting machine, a stack of packaging bags is placed on the placement plate. The placement plate is initially at a suitable height so that a certain distance is maintained between the packaging bag and the first adsorbent, and the distance can ensure that the first adsorbent effectively adsorbs the top of the packaging bag. When the bag insertion operation is required, the bag insertion part swings from the initial position to above the placement plate, and at this time, the second adsorbent also swings to a position facing the placement plate, and the first adsorbent and the second adsorbent can stably adsorb the packaging bag, and then the bag insertion part clamps the packaging bag and swings it to the filling machine for bag insertion. As the bag insertion proceeds, the number of packaging bags on the placement plate continues to decrease. In order to ensure a stable adsorption effect, the height of the placement plate gradually rises during the bag insertion process, and the distance between the first adsorbent and the second adsorbent and the packaging bag during adsorption is maintained at an appropriate distance, so that the bag insertion machine can complete the bag insertion operation. After the insertion of the packaging bags on the placement plate is completed, the placement plate returns to the initial position, and the bag insertion can continue by continuing to place the packaging bags on the placement plate.

[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, proposes a bag inserting machine, including a frame 1; a placing plate 2 is lifted and arranged on the frame 1, and the placing plate 2 is used to place packaging bags; a first adsorption member 3 is arranged on the frame 1, and the first adsorption member 3 faces the placing plate 2; a bag inserting member 4 is swingably arranged on the frame 1, and the bag inserting member 4 is used to insert bags into the filling machine or be located above the placing plate 2 after swinging; a second adsorption member 5 is swingably arranged on the frame 1, and the second adsorption member 5 faces the placing plate 2 or the bag inserting member 4 after swinging, and the placing plate 2 is configured so that when the second adsorption member 5 faces the placing plate 2, the distance between the packaging bag and the first adsorption member 3 and the second adsorption member 5 remains unchanged.

[0022] In this embodiment, in order to solve the problem that the distance between the suction device and the bag of the bag insertion machine in the related art is not convenient to adjust with the working process, which affects the success rate of bag insertion, the placement plate 2 is set on the frame 1 by lifting and lowering. By setting the placement plate 2 on the frame 1 by lifting and lowering, and ensuring that the distance between the packaging bag and the first suction piece 3 and the second suction piece 5 remains unchanged during the working process, the problem that the distance between the suction piece and the bag is not adjusted with the working process is effectively solved. In this way, the stability and accuracy of suction can be guaranteed, the success rate of bag insertion can be improved, and the situation that the suction is not firm or the packaging bag is damaged due to the change of distance can be avoided, thereby improving the overall working efficiency and packaging quality of the bag insertion machine.

[0023] Specifically, in the actual operation of the bag inserting machine, a stack of packaging bags is placed on the placement plate 2. The placement plate 2 is initially at a suitable height so that a certain distance is maintained between the packaging bag and the first adsorbent 3, and this distance can ensure that the first adsorbent 3 effectively adsorbs the top of the packaging bag. When the bag insertion operation is required, the bag insertion part 4 swings from the initial position to above the placement plate 2, and at this time the second adsorbent 5 also swings to a position facing the placement plate 2, and the first adsorbent 3 and the second adsorbent 5 can stably adsorb the packaging bag, and then the bag insertion part 4 clamps the packaging bag and swings it to the filling machine for bag insertion. As the bag insertion proceeds, the number of packaging bags on the placement plate 2 continues to decrease. In order to ensure a stable adsorption effect, the height of the placement plate 2 gradually rises during the bag insertion process, and the distance between the first adsorbent 3 and the second adsorbent 5 and the packaging bag during adsorption is kept appropriate, so that the bag insertion machine can complete the bag insertion operation. After the packaging bags on the placement plate 2 are inserted, the placement plate 2 returns to the initial position, and the bag insertion can continue by continuing to place packaging bags on the placement plate 2.

[0024] Furthermore, it also includes a limit plate 6, which is arranged on the frame 1 and has a limit groove 601; one end of the limit column 7 is arranged on the placement plate 2, and the other end is slidably arranged in the limit groove 601. The limit plate 6 is configured to drive the placement plate 2 to rise and fall after movement.

[0025] Furthermore, the limiting plate 6 is rotatably disposed on the frame 1 , the limiting plate 6 is cylindrical, and the distances between the two ends of the limiting groove 601 and the side wall of the limiting plate 6 are different.

[0026] Furthermore, there are multiple limiting grooves 601, and the multiple limiting grooves 601 are distributed on the limiting plate 6 at circumferential intervals, and also include a reset groove 602. The reset grooves 602 have multiple reset grooves 602, and the two ends of the reset groove 602 are respectively connected to two adjacent limiting grooves 601. The multiple limiting grooves 601 and the reset grooves 602 are alternately connected in sequence to form a guide groove 61.

[0027] In this embodiment, when the height of the placement plate 2 needs to be adjusted, the limiting plate 6 is moved by external force, and the limiting column 7 slides in the limiting groove 601, driving the placement plate 2 to achieve lifting and lowering movement. For example, when replacing a stack of packaging bags of different heights, the limiting plate 6 is moved to a suitable position according to the height of the packaging bags, so that the placement plate 2 is raised or lowered to the corresponding height, ensuring that the distance between the packaging bags and the adsorbent is always kept stable.

[0028] Preferably, the limiting plate 6 is rotatably mounted on the frame 1 with the rotation axis as the center, and its shape is cylindrical. The distances between the two ends of the limiting groove 601 and the side wall of the limiting plate 6 are different. When adjusting the height of the placement plate 2, the limiting plate 6 is rotated, and the limiting column 7 moves from one end of the limiting groove 601 to the other end. When the limiting column 7 moves from the end close to the axis of the limiting plate 6 to the end away from the axis, the placement plate 2 rises; otherwise, it falls. In this way, the height of the placement plate 2 can be accurately adjusted according to the stacks of packaging bags of different heights, so that the distance between the packaging bags and the adsorbent remains constant.

[0029] Furthermore, a plurality of limit grooves 601 are circumferentially spaced apart on the limit plate 6, and adjacent limit grooves 601 are connected via reset grooves 602 to form guide grooves 61. In the initial state, the limit column 7 is located in a certain limit groove 601. When it is necessary to adjust the height of the placement plate 2, the limit plate 6 is rotated, and the limit column 7 moves along the guide groove 61, from one limit groove 601 through the reset groove 602 to the adjacent limit groove 601. During the production process, through this guide groove 61 structure, the multi-level height adjustment of the placement plate 2 can be conveniently and quickly realized, and the distance between the packaging bag and the adsorbent is always kept unchanged. Through the setting of the guide groove 61, the limit plate 6 only needs to rotate in one direction to continue the bag insertion operation.

[0030] The lifting and lowering control of the placement plate 2 is realized by the cooperation of the limit plate 6 and the limit column 7, and the structure is simple and easy to operate. The height of the placement plate 2 can be accurately adjusted according to actual needs, thereby maintaining a fixed distance between the packaging bag and the adsorbent, ensuring that the bag inserter can operate stably under different packaging bag specifications, reducing bag insertion errors caused by improper height adjustment, improving production flexibility and reliability, and reducing equipment debugging time and cost. When dealing with changes in the height of various packaging bags, the placement plate 2 can be quickly and accurately placed in the appropriate position, ensuring that the distance between the adsorbent and the packaging bag is stable, and improving the adaptability of the bag inserter to different product packaging, which is conducive to improving production efficiency and consistency of product packaging quality.

[0031] Furthermore, it also includes a guide cylinder 101, which is arranged on the frame 1; one end of the guide column 201 is arranged on the placement plate 2, and the other end is lifted and lowered in the guide cylinder 101; the two ends of the first elastic member 7 act on the guide cylinder 101 and the guide column 201 respectively, so as to provide a force for the guide column 201 to move away from the guide cylinder 101.

[0032] In this embodiment, the guide cylinder 101 is fixed on the frame 1, one end of the guide column 201 is connected to the placement plate 2, and the other end is inserted into the guide cylinder 101 and can be lifted up and down. During the lifting process of the placement plate 2, when the limit plate 6 drives the placement plate 2 to descend, the first elastic member 7 is compressed to store elastic potential energy; when the placement plate 2 rises, the first elastic member 7 releases elastic potential energy to assist the placement plate 2 to rise steadily. And in the whole working process, through the cooperation of the guide cylinder 101 and the guide column 201, the linearity of the lifting and lowering of the placement plate 2 is ensured, and the distance between the packaging bag and the adsorbent is ensured to be stable. It avoids the displacement or shaking of the placement plate 2 during the lifting process, thereby ensuring that the distance between the packaging bag and the adsorbent is always constant. The setting of the first elastic member 7 plays the role of buffering and assisting lifting. On the one hand, it can absorb the impact force of the placement plate 2 during the lifting process and protect the equipment components from damage; on the other hand, it provides assistance when the placement plate 2 rises, making the descending process more stable, further improving the reliability and stability of the bag insertion machine, reducing the insertion errors caused by the unstable movement of the placement plate 2, and improving the packaging efficiency and product quality.

[0033] Furthermore, the bag insertion part 4 includes a support arm 41, which is swingably set on the frame 1, and the support arm 41 has a mounting frame 411 at one end away from the frame 1; there are two clamping arms 42, and the two clamping arms 42 are located on both sides of the mounting frame 411. One end of the two clamping arms 42 is swingably set on the mounting frame 411, and the other end has a clamping end 421, and the clamping ends 421 are used to clamp the packaging bag when they are close to each other; there are two adsorption arms 43, which are located on both sides of the mounting frame 411. One end of the two adsorption arms 43 is swingably set on the mounting frame 411, and the other end adsorbs the two sides of the packaging bag respectively, and then the filling port of the packaging bag is opened; the two ends of the connecting rod 44 are respectively hinged on the adsorption arm 43 and the clamping arm 42 located on the same side.

[0034] In this embodiment, the two clamping arms 42 are respectively located on both sides of the mounting frame 411 and connected to the mounting frame 411 through a swing shaft. The two adsorption arms 43 are also located on both sides of the mounting frame 411 and are swingably connected to the mounting frame 411. When the bag needs to be inserted, the first adsorption member 3 and the second adsorption member 5 first adsorb the packaging bag on the placement plate 2, and the support arm 41 swings to the top of the placement plate 2. After the second adsorption member 5 swings, one end of the filling port of the packaging bag enters between the two clamping ends 421. At this time, the adsorption arm 43 swings together with the clamping arm 42 under the drive of the connecting rod 44, and its end adsorbs the two sides of the packaging bag to open the filling port of the packaging bag. Finally, under the swing of the support arm 41, the bag insertion member 4 swings as a whole to insert the packaging bag into the filling machine.

[0035] This structural design of the bag insertion part 4 can realize the precise grabbing, opening and bag insertion operations of the packaging bag. Through the coordinated work of the suction arm 43 and the clamping arm 42, the filling port can be effectively opened while ensuring the stable grabbing of the packaging bag, meeting the requirements of different packaging processes. The connecting function of the connecting rod 44 makes the movements of various components coordinated and consistent, improves the automation and accuracy of the bag insertion operation, reduces manual intervention, improves the efficiency of bag insertion, and in the whole process, the lifting setting of the placement plate 2 ensures that the distance between the packaging bag and the suction part is stable, further improving the success rate of bag insertion and packaging quality.

[0036] Furthermore, the connecting rod 44 is a telescopic member.

[0037] In this embodiment, the connecting rod 44 adopts a telescopic structure, for example, a telescopic rod with adjustable length. During the bag insertion process, the filling port is opened more thoroughly after being adsorbed by the extension and retraction of the connecting rod 44, thereby improving the stability of the bag insertion machine. At the same time, under the premise of ensuring the stability of the distance between the packaging bag and the adsorption part, by adjusting the length of the connecting rod 44, the gripping and adsorption effect of the clamping arm 42 and the adsorption arm 43 on the packaging bag can be optimized, thereby improving the compatibility of the bag insertion machine with various packaging bag specifications, reducing bag insertion failures caused by changes in the size of the packaging bag, broadening the application range of the bag insertion machine, and improving the versatility and production flexibility of the equipment.

[0038] Furthermore, it also includes a first driving member 45, and a clamping arm 42 has a first connecting portion 422 and a second connecting portion 423 on both sides of the swing axis, the second connecting portion 423 is located on the other side of the clamping end 421, and the two ends of the first driving member 45 are respectively hinged on the mounting frame 411 and the second connecting portion 423; the other clamping arm 42 has a third connecting portion 424, and the third connecting portion 424 is located at the end of the clamping arm 42 away from the clamping end 421, and the two ends of the linkage rod 46 are respectively hinged on the first connecting portion 422 and the third connecting portion 424.

[0039] In this embodiment, when it is necessary to clamp the packaging bag, the first driving member 45 contracts and pulls the second connecting portion 423 to rotate the clamping arm 42 around the swing axis, and at the same time drives the other clamping arm 42 to rotate synchronously through the linkage rod 46, so that the two clamping ends 421 are close to each other to clamp the packaging bag. In this process, the suction arm 43 works in coordination with the connecting rod 44, and the placement plate 2 is kept at a suitable height to ensure that the distance between the packaging bag and the suction member remains unchanged.

[0040] The cooperation between the first driving member 45 and the linkage rod 46 realizes the synchronous and precise driving of the two clamping arms 42, ensuring that the packaging bag can be clamped stably and evenly. This driving method has a compact structure and reliable operation, which can effectively improve the clamping force and accuracy, and reduce the deviation or slipping of the packaging bag during the clamping process. Combined with the lifting function of the placement plate 2, the distance between the packaging bag and the adsorption member is guaranteed to be stable, which improves the success rate of the bag insertion operation and the packaging quality, and also improves the automation and work efficiency of the bag insertion machine.

[0041] Furthermore, the frame 1 has a conveying plane, the conveying plane has a giveway groove 102, and also includes a baffle rod 8, one end of the baffle rod 8 is swingably set on the frame 1, and the other end passes through the giveway groove 102 and is located on the conveying plane; the two ends of the return spring act on the baffle rod 8 and the frame 1 respectively; the push rod 9 is cyclically arranged on the frame 1, and after the push rod 9 moves, it is used to push the packaging bag to move in the conveying plane, and the packaging bag abuts against the baffle rod 8 and pushes the baffle rod 8 to swing and then enter the placement plate 2.

[0042] In this embodiment, a clearance groove 102 is provided on the conveying plane of the frame 1, and one end of the baffle rod 8 is installed on the frame 1 through a swing shaft, and the other end passes through the clearance groove 102 and is located above the conveying plane. The reset spring is connected between the baffle rod 8 and the frame 1, so that the baffle rod 8 is in a raised position in the initial state. The push rod 9 realizes cyclic movement on the frame 1 through a transmission mechanism such as a guide rail or a chain. When the packaging bag is pushed on the conveying plane, the packaging bag first contacts the baffle rod 8 and pushes the baffle rod 8 to overcome the elastic force of the reset spring and swing downward to enter above the placement plate 2. By setting the baffle rod 8, the packaging bags can be aligned when conveying the packaging bags, thereby improving the accuracy of bag insertion. The combination of the baffle rod 8, the reset spring and the push rod 9 realizes the orderly positioning of the packaging bags on the conveying plane.

[0043] A bag inserting method uses the above-mentioned bag inserting machine.

[0044] In this embodiment, a bag insertion method is proposed, in which the distance between the packaging bag and the first adsorption component 3 and the second adsorption component 5 is adjusted by lifting and lowering the placement plate 2 during the bag insertion process. This improves the accuracy and stability of bag insertion. In the actual operation of the bag insertion machine, a stack of packaging bags is placed on the placement plate 2. The placement plate 2 is initially at a suitable height so that a certain distance is maintained between the packaging bag and the first adsorption component 3, and this distance can ensure that the first adsorption component 3 effectively adsorbs the top of the packaging bag. When the bag insertion operation is required, the bag insertion component 4 swings from the initial position to above the placement plate 2, and at this time the second adsorption component 5 also swings to a position facing the placement plate 2, and the first adsorption component 3 and the second adsorption component 5 can stably adsorb the packaging bag, and then the bag insertion component 4 clamps the packaging bag and swings it to the filling machine for bag insertion. As the bag insertion proceeds, the number of packaging bags on the placement plate 2 continues to decrease. In order to ensure a stable adsorption effect, the height of the placement plate 2 gradually rises during the bag insertion process, and the distance between the first adsorption component 3 and the second adsorption component 5 and the packaging bags is kept appropriate during adsorption, so as to facilitate the bag insertion machine to complete the bag insertion operation. After the packaging bags on the placement plate 2 are inserted, the placement plate 2 returns to its initial position, and the bag insertion can continue by continuing to place packaging bags on the placement plate 2.
