Description

Technical Field

[0001] The utility model relates to the technical field related to bag making, in particular to a bag sorting device for packaging bags. Background Art

[0002] Packaging bags are closely related to our lives. Packaging bags include non-woven bags, paper bags, plastic bags, etc. Taking non-woven bags as an example, non-woven bags are environmentally friendly and practical. They have been vigorously promoted and used in recent years, which has led to the rapid development of non-woven bag making automatic forming technology. However, with the development of non-woven fabrics in my country in recent years, a vicious cycle of price competition has emerged among domestic industries. Only by finding technology-intensive processes and producing high-value-added products such as multiple varieties, composites, high quality, and differentiation can each company survive. Therefore, three-dimensional bags with a strong sense of three-dimensionality have become the mainstream of non-woven bags. The existing three-dimensional non-woven bags are formed by a one-time processing of a three-dimensional bag forming machine. During the processing, the flat non-woven fabric needs to be pressed into a cuboid through a mold lifting device. After the non-woven fabric is processed into a non-woven three-dimensional bag, in order to facilitate packing and transportation, each three-dimensional bag needs to be flattened, sorted into piles, and then packaged and transported together. The existing non-woven three-dimensional bag forming machine is usually equipped with a bag folding machine to fold and flatten the formed three-dimensional bag, and then manually sort it into piles for packaging. The material collection is time-consuming and labor-intensive, and the processing efficiency is low.

[0003] For example, a Chinese patent with publication number CN207172864U discloses a vertical bag sorting machine, which includes a pushing mechanism, a front stop mechanism and a rear stop mechanism, and can sort the folded non-woven bags. However, after sorting a certain number of non-woven bags, the non-woven bags need to be sorted and carried out manually, and assembly line operation cannot be achieved, which is time-consuming, labor-intensive and has low processing efficiency. Utility Model Content

[0004] The utility model aims to solve the problem that after a certain number of non-woven bags have been sorted by a bag sorting machine in the prior art, the non-woven bags need to be sorted out manually, and assembly line operation cannot be achieved, which is time-consuming, labor-intensive and has low processing efficiency.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a bag sorting device for packaging bags, and the bag sorting device comprises:

[0006] The bag dropping platform is provided with a bag dropping platform for receiving the packaging bags, and the packaging bags fall onto the bag dropping platform along the bag dropping direction.

[0007] The bag pushing mechanism is arranged above the bag dropping platform. The bag pushing mechanism includes a bag pushing driving assembly and a bag pushing assembly which are transmission-connected. The bag pushing driving assembly drives the bag pushing assembly to move back and forth along the bag sorting direction of the packaging bags and pushes the packaging bags dropped on the bag dropping platform.

[0008] The upper bag-blocking mechanism is arranged on the front side of the bag-pushing mechanism along the bag-aligning direction and above the bag-dropping pedestal. The upper bag-blocking mechanism includes an upper bag-blocking member which can reciprocate along the bag-dropping direction and switch between the bag-blocking state and the yielding state.

[0009] The lower bag-blocking mechanism is arranged on the bag-dropping pedestal. The lower bag-blocking mechanism includes a lower bag-blocking member protruding from the bag-dropping platform.

[0010] When the upper bag-blocking member is in the bag-blocking state, a bag-aligning space is formed between the upper bag-blocking member and the bag-pushing mechanism for the bag-pushing assembly to reciprocate along the bag-aligning direction. And when a predetermined number of packaging bags have fallen into the bag-aligning space, the upper bag-blocking member moves along the bag-dropping direction away from the packaging bags and switches from the bag-blocking state to the yielding state, separating the upper bag-blocking member from the packaging bags, and the bag-pushing assembly pushes a predetermined number of packaging bags to move along the bag-aligning direction. And the bag-dropping direction of the packaging bags is the vertical direction, and the bag-aligning direction of the packaging bags is the horizontal direction.

[0011] Adopting the above technical solution, the bag-aligning device for packaging bags disclosed in the present application includes a bag-dropping pedestal, a bag-pushing mechanism, an upper bag-blocking mechanism and a lower bag-blocking mechanism. Among them, the bag-dropping pedestal provides a platform for receiving the dropped packaging bags, ensuring that the packaging bags fall smoothly on the bag-dropping platform. The bag-pushing driving assembly and the bag-pushing assembly in the bag-pushing mechanism cooperate. Every time a packaging bag drops, the bag-pushing assembly pushes once in the bag-aligning space, and pushes a plurality of packaging bags to the side of the upper bag-blocking mechanism and the lower bag-blocking mechanism one by one at a certain rate. Therefore, the whole bag-aligning process has the advantages of full automation and high efficiency.

[0012] Furthermore, when a predetermined number of packaging bags are sorted in the bag-aligning space, the upper bag-blocking member can move away from the packaging bags and switch from the bag-blocking state to the yielding state. The purpose of this setting is that the upper bag-blocking member leaves a separation space so that a predetermined number of packaging bags can leave the bag-aligning space. A predetermined number of packaging bags can leave through the pushing of the bag-pushing assembly, can be taken by a bag-holding manipulator, or can be grabbed and left the bag-aligning space by a grasping robotic arm. Therefore, for the bag-aligning device disclosed in the present application, by setting a movable and adjustable upper bag-blocking mechanism, after the packaging bags reach a predetermined number, by moving and yielding, it is convenient for a predetermined number of packaging bags to leave the bag-aligning device, providing convenience for subsequent packing or other steps, and there is no need for workers to manually carry out or take away the packaging bags, and it can realize assembly line operation, greatly improving the production efficiency of the packaging bags. In summary, the bag-aligning device for packaging bags provided by the present application has multiple advantages such as improving production efficiency, enhancing product quality, reducing labor intensity and risk, saving costs and being environmentally friendly.

[0090] A. Vertical direction; B. Horizontal direction; Specific embodiments

[0091] With the development of technology, there are more and more types of packaging bags, and the bag-making machines for packaging bags are becoming more and more mature. Common packaging bags include non-woven bags, paper bags, plastic bags, etc. Taking non-woven bags as an example, non-woven bags have the characteristics of environmental protection and practicality, and have been vigorously promoted and used in recent years, thus promoting the rapid development of the fully automatic forming technology for non-woven bag making.

[0092] Existing non-woven bag-making machines generally include a forming machine and a bag folding machine. The forming machine for non-woven bags cuts non-woven fabrics into sheet materials and then performs forming processing to form a three-dimensional and complete non-woven bag. The bag folding machine flattens and folds the completely formed non-woven bag, thus completing the forming and bag folding processing of the non-woven bag. The non-woven bags after the bag folding processing are sorted and collected and packed through the manual collection and folding method.

[0093] With the development of technology, a bag sorting machine has gradually emerged. The bag sorting machine can sort the folded non-woven bags one by one. However, after sorting multiple non-woven bags, it is still necessary to manually or manually pack the non-woven bags for subsequent processing. Specifically, after sorting a certain number of non-woven bags, it is necessary to manually sort and carry out the non-woven bags, and still cannot realize assembly line operation, resulting in time-consuming, laborious and low processing efficiency.

[0094] To solve the problems that the non-woven bags cannot realize assembly line operation after bag sorting, are time-consuming, laborious and have low processing efficiency, the present utility model discloses a bag sorting device for packaging bags. By providing an upper bag blocking member that can be switched from a bag blocking state to a retracting state, when the packaging bags reach a predetermined number, the upper bag blocking member retracts and leaves a separation space to facilitate the packaging bags to leave the bag sorting device for subsequent packing or other processing. The whole process is completed through mechanical control and does not require manual handling by workers, having the advantages of high automation rate and production efficiency.

[0095] Next, a complete and detailed description of the bag sorting device for packaging bags disclosed in the present application will be given with reference to the accompanying drawings:

[0096] The implementation of this embodiment discloses a bag sorting device for packaging bags, which includes a bag dropping platform 100, a bag pushing mechanism 200, an upper bag blocking mechanism 300 and a lower bag blocking mechanism 400. For details, please refer to Figure 1 and Figure 2 The bag dropping seat 100 is provided with a bag dropping platform 110 for receiving the packaging bags, and the packaging bags fall onto the bag dropping platform 110 along the bag dropping direction. It should be noted that in one implementation of the present application, the packaging bags fall onto the bag dropping platform 110 along the vertical direction, so the conveying mechanism or conveyor belt of the packaging bags must be at least arranged above the bag dropping seat 100, or the bag dropping seat 100 is arranged below the discharge end or the conveyor belt to ensure that each packaging bag can be pushed for bag sorting in a timely and smooth manner after falling.

[0097] The bag pushing mechanism 200 is arranged above the bag dropping platform 100. The bag pushing mechanism 200 includes a bag pushing driving component 210 and a bag pushing component which are connected in a transmission manner. The bag pushing driving component 210 drives the bag pushing component to move back and forth along the bag sorting direction of the packaging bag and push the packaging bag dropped on the bag dropping platform 110. Specifically, the bag pushing mechanism 200 can move back and forth along the bag sorting direction of the packaging bag and push the packaging bag after the packaging bag drops. Therefore, the bag pushing driving component 210 can be various mechanical structures that can move back and forth. For example, the bag pushing driving component 210 can be a pneumatic pump or a pneumatic guide rail to drive the bag pushing component to move back and forth, or a linear motor to drive the bag pushing component to move back and forth, or a motor and a conveyor belt or a synchronous belt to work together to drive the bag pushing component to move back and forth, or a motor and a gear rack or a worm gear or a screw mechanism to work together to drive the bag pushing component to move back and forth. Those skilled in the art can design or select according to actual needs, and this embodiment does not make specific limitations on this. Furthermore, the bag pushing assembly can be configured as a bag pushing plate, a bag pushing frame, a bag pushing bar, or the like that can realize bag pushing structures.

[0098] The upper bag-blocking mechanism 300 is arranged on the front side of the bag-pushing mechanism 200 along the bag-aligning direction and above the bag-dropping pedestal 100. The upper bag-blocking mechanism 300 includes an upper bag-blocking member 310 which can reciprocate along the bag-dropping direction and switch between the bag-blocking state and the yielding state. The upper bag-blocking member 310 can also be linearly driven by mechanisms such as a pneumatic pump or a pneumatic guide rail, or can be driven by the cooperation of a motor and a transmission mechanism. Further, it should be understood that the bag-blocking state means that at this time, the upper bag-blocking member 310 can block in front of the bag-pushing mechanism 200 for limiting. When the bag-pushing mechanism 200 pushes the packaging bag forward for bag alignment, it blocks and limits in front of the bag-pushing mechanism 200, so as to align the packaging bags on one side close to the upper bag-blocking member 310. Each time a packaging bag is pushed, the number of aligned packaging bags increases by one. When the predetermined number is reached, the upper bag-blocking member 310 yields and separates from the packaging bag and performs subsequent processing.

[0099] The lower bag-blocking mechanism 400 is arranged on the bag-dropping pedestal 100. The lower bag-blocking mechanism 400 includes a lower bag-blocking member 420 protruding from the bag-dropping platform 110. The lower bag-blocking member 420 also aligns and blocks the packaging bags, and the lower bag-blocking can play an auxiliary role in limiting and blocking.

[0100] When the upper bag-blocking member 310 is in the bag-blocking state, a bag-aligning space is formed between the upper bag-blocking member 310 and the bag-pushing mechanism 200 for the bag-pushing assembly to reciprocate along the bag-aligning direction. And when a predetermined number of packaging bags fall into the bag-aligning space, the upper bag-blocking member 310 moves along the bag-dropping direction away from the packaging bags and switches from the bag-blocking state to the yielding state, separating the upper bag-blocking member 310 from the packaging bags, and the bag-pushing assembly pushes the predetermined number of packaging bags to move along the bag-aligning direction. And the bag-dropping direction of the packaging bag is the vertical direction, and the bag-aligning direction of the packaging bag is the horizontal direction. Wherein the vertical direction (bag-dropping direction) is as Figure 1 shown by the A direction in Figure 1 and the horizontal direction (bag-aligning direction) is as

[0101] Next, refer to Figure 1Specifically, in the bag dropping pedestal 100, the bag pushing mechanism 200, the upper bag blocking mechanism 300, and the lower bag blocking mechanism 400 disclosed in the present application, the bag dropping pedestal 100 needs to be at least arranged below the bag pushing mechanism 200 and the upper bag blocking mechanism 300 to ensure the work of receiving the packaging bag and the bag pushing process of the bag pushing mechanism 200. And the bag arranging space between the upper bag blocking mechanism 300 and the bag pushing mechanism 200 is at least larger than the stroke space of the bag pushing mechanism 200. It can be understood that the bag arranging space is composed of the stroke space of the bag pushing mechanism 200 and the space for arranging and stacking the packaging bags, and the space for arranging and stacking the packaging bags can be adjusted. For example, the space for arranging and stacking the packaging bags can be to arrange and stack 10, 15, 20 or other numbers of packaging bags at a time. When the number of arranged and stacked packaging bags is different, the volume of the space for stacking the packaging bags is also different. And preferably, the space for arranging and stacking the packaging bags is set to be smaller than the stroke space of the bag pushing mechanism 200. In this way, when the packaging bags falling into the stroke space of the bag pushing mechanism 200 are pushed by the bag pushing mechanism 200 into the space for arranging and stacking the packaging bags, they are neater, which is more convenient for subsequent steps such as bag holding and packing.

[0102] When the upper bag blocking member 310 is in the bag blocking state, a bag arranging space for the bag pushing assembly to reciprocate along the bag arranging direction is formed between the upper bag blocking member 310 and the bag pushing mechanism 200, and the space on the side close to the upper bag blocking member 310 is the space for arranging and stacking the packaging bags. When the arranged packaging bags reach the predetermined quantity, at this time, the upper bag blocking member 310 moves in the direction away from the packaging bags and switches from the bag blocking state to the yielding state, and at this time, a bag separation opening is left to facilitate the separation of the arranged packaging bags.

[0103] As can be seen from the above, the bag dropping pedestal 100 disclosed in the present application provides a platform for receiving the falling packaging bags to ensure that the packaging bags fall steadily on the bag dropping platform 110. The bag pushing driving assembly 210 and the bag pushing assembly in the bag pushing mechanism 200 cooperate to work. Every time a packaging bag falls, the bag pushing assembly pushes once in the bag arranging space, and pushes a plurality of packaging bags to the side of the upper bag blocking mechanism 300 and the lower bag blocking mechanism 400 one by one at a certain rate. Therefore, the whole bag arranging process has the advantages of full automation and high efficiency.

[0104] Further, when a predetermined number of packaging bags are arranged in the bag arranging space, the upper bag blocking member 310 can move away from the packaging bags and switch from the bag blocking state to the retracting state. The purpose of this setting is that the upper bag blocking member 310 leaves a separation space, so that the packaging bags reaching the predetermined number can leave the bag arranging space. The packaging bags reaching the predetermined number can leave by being pushed by the bag pushing assembly, or by being picked up by the bag holding manipulator, or by being grabbed by the grabbing robotic arm and grabbed away from the bag arranging space. Therefore, for the bag arranging device disclosed in the present application, by setting the movable and adjustable upper bag blocking mechanism 300, after the packaging bags reach the predetermined number, the packaging bags reaching the predetermined number can leave the bag arranging device conveniently by moving and retracting, providing convenience for subsequent packing or other steps, and there is no need for workers to manually carry out or take away the packaging bags, enabling assembly line operation and greatly improving the production efficiency of the packaging bags. In summary, the bag arranging device for packaging bags provided in the present application has multiple advantages such as improving production efficiency, enhancing product quality, reducing labor intensity and risks, saving costs, and being environmentally friendly and green.

[0105] Next, the specific structure of the upper bag blocking mechanism 300 will be described first:

[0106] Please refer to Figure 1 and Figure 2 In the upper bag blocking mechanism 300 includes a top fixing frame 320, a driving component, and an upper bag blocking member 310. The top fixing frame 320 is fixedly arranged on the device body of the bag arranging device. The driving component is fixedly arranged on the top fixing frame 320. The upper bag blocking member 310 is arranged on the top fixing frame 320 so as to reciprocate along the bag dropping direction and is located on the side of the driving component close to the bag dropping platform 110. And, the power output end of the driving component is connected to the upper bag blocking member 310. It should be noted that Figure 1 and Figure 2 in the views shown, the upper bag blocking member 310 is located on the side pushed to be close to the upper bag blocking member 310.

[0107] Specifically, in this embodiment, the driving component can be any one of a linear driving motor, a driving cylinder, and a pneumatic guide rail, or the driving up and down can also be realized by components such as a motor and a transmission lead screw, and a rack conveyor belt. And, to ensure the running stability of the upper bag blocking member 310, at least two guiding components are arranged on both sides of the driving component. The guiding components can be guiding rods, guiding grooves, etc. This embodiment does not make specific limitations on this.

[0108] Further preferably, please refer to Figure 2The upper bag-blocking component 310 includes an upper bag-blocking plate, and the driving component includes a first driving cylinder 330 and a driving rod 340. One end of the driving rod 340 is arranged at the power output end of the first driving cylinder 330, and the other end is fixedly connected to the upper bag-blocking plate. The first driving cylinder 330 can drive the driving rod 340 to reciprocate along the bag-dropping direction and drive the upper bag-blocking plate to reciprocate along the bag-dropping direction.

[0109] With this structural design, the top fixed frame 320 provides an installation or fixing position for the driving component, and the driving component drives the upper bag blocking component 310 to reciprocate along the bag dropping direction. The upper bag blocking component 310 is provided with an upper bag blocking plate, which has the advantages of a large bag blocking area and a good bag blocking effect. The driving component is configured to be driven by the first driving cylinder 330 and the driving rod 340, which has the advantages of simple structure and working mode, low cost, smooth operation, precise control, high flexibility and adaptability, and high efficiency and reliability.

[0110] The embodiment of the utility model also discloses a bag sorting device for packaging bags. A counting component (not shown in the figure) is also provided on one side of the top fixing frame 320 close to the upper bag blocking member 310 and at the entrance of the bag sorting space. The counting component includes any one of a counter, a counting motor, and a counting sensor. The counting component can accurately count the packaging bags dropped on the bag dropping platform 110. When the number of dropped sorted bags reaches a predetermined number, the operation of pushing or holding the bags is performed. For example, when the counting component is set as a counter, it can be a binary counter or a BCD counter. When it is set as a counting motor, it can be an inductive counting motor. When it is set as a counting sensor, it can be a photoelectric counting sensor, a sound counting sensor, a trigger counting sensor, etc. This embodiment does not make specific limitations on this.

[0111] Next, the lower bag blocking mechanism 400 in the bag sorting device is described in detail:

[0112] The embodiment of the present invention also discloses a bag sorting device for packaging bags, wherein the lower bag blocking mechanism 400 comprises a transmission-connected telescopic driving component 410 and a lower bag blocking member 420. The telescopic driving component 410 is fixedly arranged on the back of the bag dropping platform 110, and the telescopic driving component 410 links the lower bag blocking member 420 to reciprocate along the bag dropping direction and protrude from the plane where the bag dropping platform 110 is located.

[0113] Specifically, in the present embodiment, the telescopic drive component 410 can be any one of a linear drive motor, a drive cylinder, and a pneumatic guide rail. Further preferably, the telescopic drive component 410 includes a second drive cylinder (not shown in the figure), which is fixedly arranged on the back of the bag dropping platform 100, and the output end of the second drive cylinder is transmission-connected to the lower bag blocking component 420.

[0114] The lower bag blocking member 420 includes telescopic stop rods, and there are at least two telescopic stop rods. An activity groove 120 is provided in the middle of the bag dropping platform 110. The activity groove 120 extends along the bag arranging direction on the bag dropping platform 110. The two telescopic stop rods are spaced and arranged in the activity groove 120. Moreover, the second driving cylinder can drive the end of the telescopic stop rod to protrude from the plane where the bag dropping platform 110 is located through the activity groove 120; or, the second driving cylinder can drive the end of the telescopic stop rod to be located on the back of the bag dropping platform 110 through the activity groove 120.

[0115] Specifically, in the bag arranging device of the packaging bag disclosed in this embodiment, it can be set that a group of lower bag blocking members 420 are 2 telescopic stop rods. One group, two groups, three groups or other numbers of lower bag blocking members 420 can be arranged on the bag dropping platform 110. Each group of lower bag blocking members 420 is correspondingly provided with 1 activity groove 120. The 2 telescopic stop rods on each group of lower bag blocking members 420 are spaced and arranged in the activity groove 120. It should be noted that the distance between the 2 telescopic stop rods in the same activity groove 120 is equal to the thickness of a predetermined number of packaging bags, and the distance between the 2 telescopic stop rods can be adjusted according to the thickness of different numbers of packaging bags. For example, when the predetermined number of packaging bags is 10, the distance between the telescopic stop rods is 10 cm; when the predetermined number of packaging bags is 15, the distance between the telescopic stop rods is 15 cm; when the predetermined number of packaging bags is 20, the distance between the telescopic stop rods is 20 cm. Those skilled in the art can design and select according to actual needs, and this embodiment does not make specific limitations on this. And the telescopic stop rod on the side of the 2 telescopic stop rods close to the bag pushing assembly can also stop and limit the packaging bag to prevent the sorted packaging bags from retreating into the stroke space of the bag pushing mechanism 200.

[0116] It should be noted that as Figure 3 shown, in this embodiment, 3 groups of lower bag blocking members 420 are provided, and the telescopic stop rods in each group of lower bag blocking members 420 are all telescopic in the activity groove 120 on the back of the bag dropping platform 110.

[0117] Adopting the above technical solution, the telescopic driving component 410 is set as a driving cylinder, which also has the advantages of simple structure and working mode, low cost, stable operation, precise control, high flexibility and adaptability, and high efficiency and reliability.

[0118] Furthermore, the lower bag blocking member 420 includes two telescopic stop rods arranged at intervals. There is a certain interval between the two telescopic stop rods, providing a set reserved space for a plurality of sorted packaging bags, and pushing the sorted plurality of packaging bags into the reserved space for sorting and stacking the packaging bags, avoiding the sorted plurality of packaging bags from retreating into the stroke space of the bag pushing mechanism 200 again.

[0119] Further, a simple example is given based on the bag arranging process of the bag arranging device:

[0120] For example, in one way of arranging bags, it is preset that the number of bags to be arranged is 15 packaging bags. Each time a packaging bag drops, the bag pushing mechanism 200 pushes the packaging bag into the space for sorting and stacking the packaging bags. At this time, the upper bag blocking member 310 and the lower bag blocking member 420 block and limit the packaging bags. The counting component calculates the number of dropped and pushed packaging bags. When the number of sorted and pushed packaging bags reaches 15 packaging bags, the upper bag blocking member 310 and the lower bag blocking member 420 retract to leave a separation opening. The upper bag blocking member 310 switches from the bag blocking state to the yielding state. The bag pushing assembly pushes the 15 sorted packaging bags away from the bag arranging device for subsequent packing and collecting steps, and the upper bag blocking member 310 and the lower bag blocking member 420 reset to block and limit the bags.

[0121] For example, in another way of arranging bags, a simple description is given in the way of the cooperation between the bag arranging device and the bag holding manipulator. It is also preset that the number of bags to be arranged is 15 packaging bags. The bag pushing mechanism 200 pushes the packaging bags into the space for sorting and stacking the packaging bags. At this time, the upper bag blocking member 310 and the lower bag blocking member 420 block and limit the packaging bags. The counting component calculates the number of dropped and pushed packaging bags. And the bag holding manipulator is located on one side close to the upper bag blocking member 310 and the lower bag blocking member 420. When the number of sorted and pushed packaging bags reaches 15 packaging bags, the upper bag blocking member 310 and the lower bag blocking member 420 retract to leave a separation opening. The upper bag blocking member 310 switches from the bag blocking state to the yielding state. The bag holding manipulator takes away 15 packaging bags for subsequent packing processing. Or when the counting component calculates that the number of dropped and pushed packaging bags reaches 10 packaging bags, the upper bag blocking member 310 and the lower bag blocking member 420 retract to leave a separation opening. The upper bag blocking member 310 switches from the bag blocking state to the yielding state, and continues to push and sort the packaging bags. When the number of sorted and pushed packaging bags reaches 15 packaging bags, the bag holding manipulator takes away 15 packaging bags for subsequent packing processing, and the upper bag blocking member 310 and the lower bag blocking member 420 reset to block and limit the bags.

[0122] It should be noted that only two implementation manners are given in this embodiment. Those skilled in the art can also set other specific structures or operation steps for bag arranging and separating the packaging bags according to specific requirements. However, it should be noted that the solutions of counting the sorted packaging bags and enabling the upper bag blocking member 310 to switch between the bag blocking state and the yielding state after reaching the predetermined number are all within the protection scope of this application.

[0123] The implementation manner of this embodiment also discloses a bag arranging device for packaging bags. Please refer to Figure 3, a detachable limiting assembly is further provided on both sides of the lower bag retaining member 420 on the bag dropping platform 110. The detachable limiting assembly includes a first limiting block 130 and a second limiting block 140 detachably arranged on the bag dropping platform 110. The distance between the first limiting block 130 and the second limiting block 140 is adjustable, and the first limiting block 130 and the second limiting block 140 are symmetrically arranged on both sides of the lower bag retaining member 420.

[0124] Both the first limiting block 130 and the second limiting block 140 protrude from the plane where the bag dropping platform 110 is located, and the opposite sides of the first limiting block 130 and the second limiting block 140 are respectively adapted to the bottom bag side edges of the packaging bag.

[0125] With this structural design, the first limiting block 130 and the second limiting block 140 limit the packaging bag. The first limiting block 130 and the second limiting block 140 are adapted to the bottom bag side edges of the packaging bag, which can assist in limiting the packaging bag and prevent the phenomenon that the packaging bag stands unstably and tilts, thereby ensuring more efficient and stable bag arranging.

[0126] Further preferably, the parts of the first limiting block 130 and the second limiting block 140 protruding from the bag dropping platform 110 are both in the shape of a hollow right trapezoid, and when looking at the first limiting block 130 and the second limiting block 140 from the bag arranging direction of the packaging bag, the spaced part between the first limiting block 130 and the second limiting block 140 is in a "V" shape.

[0127] For example, when the side edges of the bottom bag of the packaging bag are in a "V" shape, or when the size of the bottom bag of the packaging bag is small, there will inevitably be a problem that the packaging bag stands unstably. At this time, the spaced part between the first limiting block 130 and the second limiting block 140 is in a "V" shape, which is adapted to the bottom of the "V" - shaped packaging bag to prevent the packaging bag from tilting during bag arranging, so as to improve the stability of the packaging bag during the bag arranging process.

[0128] Next, a detailed description will be given to the bag pushing mechanism 200 of the bag arranging device disclosed in the present application:

[0129] Please refer to Figure 1 and Figure 2 , the bag pushing drive assembly 210 is arranged on the device body of the bag arranging device and is located on the side of the bag pushing assembly. The bag pushing drive assembly 210 includes a bag pushing drive unit, a transmission member (not shown in the figure), and a moving guiding member (not shown in the figure).

[0130] Both the transmission member and the moving guiding member extend along the same direction as the bag arranging direction of the packaging bag. The output end of the bag pushing drive unit is in transmission connection with the transmission member, and the transmission member drives the moving guiding member to reciprocate along the bag arranging direction of the packaging bag. Moreover, the moving guiding member is in transmission connection with the end of the bag pushing assembly.

[0131] Specifically, in this embodiment, the bag pushing driving unit can be a common driving cylinder, driving motor, etc. Taking the driving cylinder as an example, the bag pushing driving unit is set as a driving cylinder, and the transmission component can be set as a cylinder guide rod. The driving cylinder drives the cylinder guide rod to move back and forth, and the cylinder guide rod is linked to move the guide component to move back and forth along the bag sorting direction of the packaging bag. Taking the driving motor as an example, the bag pushing driving unit is set as a driving motor (not shown in the figure), and the transmission component can be a gear rack mechanism, a worm gear mechanism, a screw mechanism, or a gear conveyor belt mechanism, which can realize the output of the rotation of the driving motor as the linear movement of the moving guide component.

[0132] More specifically, the movable guide component can be set as a sliding guide structure, a movable guide structure, a rolling guide structure, etc. For example, the movable guide component can be set as a rolling guide groove and a rolling element, and the rolling element can be set as a roller, a ball, etc. to roll and adjust in the rolling guide groove, or when it is set as a slide rail and a slider, the slider can be slidably set on the slide rail to slide. Those skilled in the art can design according to actual needs, and this embodiment does not make specific limitations on this. The present application enables the bag pushing assembly to move back and forth in the bag sorting space through the transmission coordination of the bag pushing drive unit, the transmission component, and the movable guide component. Every time a packaging bag is dropped, it is pushed and sorted once, which has the advantages of high efficiency and speed.

[0133] Further preferably, the bag pushing drive unit comprises a bag pushing drive motor fixedly arranged on the device body.

[0134] See also Figure 1 and Figure 2 The transmission component includes a transmission rod 213, a first transmission group and a second transmission group. The transmission rod 213 extends in a direction perpendicular to the bag sorting direction. The first transmission group and the second transmission group are arranged at intervals on both sides of the bag pushing plate 240 along the width direction of the bag pushing assembly, and are respectively connected to the two side ends of the transmission rod 213. The transmission rod 213 is connected to the output end of the bag pushing drive motor. The two side ends of the transmission rod 213 are respectively provided with a first transmission tooth 2131 and a second transmission tooth 2132. The first transmission tooth 2131 is connected to the first transmission group, and the second transmission tooth 2132 is connected to the second transmission group. That is, the present application controls the first transmission group and the second transmission group through synchronous transmission of a transmission rod 213.

[0135] And in this embodiment, a speed reduction belt group is further provided between the bag pushing drive motor and the transmission rod 213. The speed reduction belt group includes a motor driving gear 211 and a motor driven gear 212. The motor driving gear 211 is connected to the power output end of the bag pushing drive motor. The motor driven gear 212 is coaxially arranged with the transmission rod 213, and the motor driving gear 211 and the motor driven gear 212 are connected by belt winding for transmission.

[0136] Please refer to Figure 1 , the first transmission group includes a first driven gear 214 rotatably arranged on the device body, and a first transmission belt 215 surrounding the first transmission tooth 2131 and the first driven gear 214. The second transmission group includes a second driven gear 216 rotatably arranged on the device body, and a second transmission belt 217 surrounding the second transmission tooth 2132 and the second driven gear 216.

[0137] The moving guiding member includes a first moving group 218 and a second moving group 219 respectively adapted to the first transmission group and the second transmission group. The first moving group 218 includes a first moving guide rail 2181 fixedly arranged on the device body, and a first moving block 2182 movably arranged on the first moving guide rail 2181. The first moving block 2182 is fixedly connected to a corresponding part of the first transmission belt 215. The second moving group 219 includes a second moving guide rail 2191 fixedly arranged on the device body, and a second moving block 2192 movably arranged on the second moving guide rail 2191. The second moving block 2192 is fixedly connected to a corresponding part of the second transmission belt 217.

[0138] The bag pushing drive motor drives the transmission rod 213 to rotate, and drives the first transmission group and the second transmission group to reciprocate. The first transmission group and the second transmission group respectively drive the first moving group 218 and the second moving group 219 to reciprocate, and drive the bag pushing assembly to reciprocate along the bag arranging direction of the packaging bag.

[0139] With the design of the above structure, the first transmission group and the second transmission group are respectively arranged on both sides of the bag pushing plate 240, which has the advantages of high efficiency and stability during transmission. And by using a single transmission rod 213 to drive the first transmission group and the second transmission group simultaneously, synchronous driving can be achieved. Further setting the transmission belt has the advantages of high transmission efficiency, high transmission precision, high stability and high reliability. Setting the moving guiding member, through the cooperation of the moving guide rail and the moving block, has the advantages of smooth movement process and timely response.

[0140] Further, please refer to Figure 1, The bag pushing assembly includes a bag pushing frame 230 and a bag pushing plate 240. The bag pushing plate 240 is fixedly arranged on the bag pushing frame 230. Among them, when looking at the bag pushing assembly from above the bag pushing assembly, the bag pushing frame 230 is in a "U" shape. The two side ends of the bag pushing frame 230 are respectively fixedly connected to the moving blocks of the first moving group 218 and the second moving group 219. The bag pushing plate 240 is fixedly arranged at the front end of the bag pushing frame 230.

[0141] The bag pushing plate 240 is in a "cross" shape, and the bag pushing plate 240 is arranged parallel to the packaging bag that falls on the bag dropping platform 110.

[0142] With the design of the above structure, the bag pushing frame 230 is in a "U" shape. Therefore, it is ensured that the two side ends of the bag pushing frame 230 are respectively fixedly connected to the moving blocks of the first moving group 218 and the second moving group 219. Driving through the two sides of the bag pushing frame 230 has the advantage of stable operation. It should be noted that the bag pushing plate 240 being in a "cross" shape is just one of the setting methods. The bag pushing plate 240 can also be set as, for example, a rectangular plate to increase the bag pushing area.

[0143] Further preferably, a sensor is arranged on the side of the bag pushing plate 240 facing the packaging bag. The sensor can be a common infrared sensor, or can be set as a displacement sensor, a photosensitive sensor, etc. The present embodiment does not make specific limitations on this. With the above technical solution, setting the sensor can sense and detect in time when the packaging bag drops, ensuring that the bag pushing and sorting can be carried out in time and accurately after each bag drop.

[0144] The embodiment of the present invention also discloses a bag arranging device for packaging bags, which further includes a side bag patting assembly. The side bag patting assembly includes a first bag patting group 500 and a second bag patting group 600 symmetrically arranged on both sides of the bag arranging space.

[0145] Please refer to Figure 2 and Figure 4 , The first bag patting group 500 includes a first mounting frame 510, a first driving part 520, a first driving gear 530, a first driven rack 540 and a first bag patting plate 550. The first mounting frame 510 is arranged on the device body of the bag arranging device. The first driving part 520 is fixedly arranged on the first mounting frame 510. The first bag patting plate 550 is movably arranged on the first mounting frame 510 along the bag patting direction, and one end extends into the bag arranging space. The first driven rack 540 is fixedly arranged on one side of the first bag patting plate 550; among them, the output end of the first driving part 520 is fixedly connected to the first driving gear 530 and drives the first driving gear 530 to rotate. The first driving gear 530 meshes with the first driven rack 540 and drives the first bag patting plate 550 to reciprocate along the bag patting direction.

[0146] The second bag-slapping group 600 includes a second mounting frame 610, a second driving unit 620, a second driving gear 630, a second driven rack 640 and a second bag-slapping board 650. The second mounting frame 610 is arranged on the device body, the second driving unit 620 is fixedly arranged on the second mounting frame 610, the second bag-slapping board 650 is movably arranged on the second mounting frame 610 along the bag-slapping direction, one end of which extends into the bag-arranging space, and the second driven rack 640 is fixedly arranged on one side of the second bag-slapping board 650; the output end of the second driving unit 620 is fixedly connected to the second driving gear 630 and drives the second driving gear 630 to reciprocate, the second driving gear 630 is meshed with the second driven rack 640 for transmission, and the second bag-slapping board 650 is linked to reciprocate along the bag-slapping direction.

[0147] The bag beating direction is perpendicular to the bag dropping direction and the bag sorting direction, and the bag beating direction is a horizontal direction.

[0148] It should be noted that the bag-beating board is only one of the specific implementation methods through the motor-driven gear rack. Those skilled in the art can also set it to, for example, a drive motor plus a conveyor belt, a drive motor plus a cam mechanism, or a drive motor plus a connecting rod mechanism. That is to say, the scheme of converting the rotation of the drive motor into intermittent reciprocating swing is within the protection scope of this application. With this design, the side bag-beating assembly includes a first bag-beating group 500 and a second bag-beating group 600 symmetrically arranged on both sides of the bag sorting space, which can conveniently and timely beat the two sides of the packaging bag, so that the packaging bags are more neat when sorting.

[0149] Further preferably, the first bag-beating board 550 and the second bag-beating board 650 both include a strip-shaped moving board 560 and a bag-beating board fixedly disposed at one end of the moving board 560 , and the cross section of the bag-beating board is “L”-shaped.

[0150] Furthermore, in order to improve the efficiency of bag beating, bag beating cylinders can also be set on both sides of the first bag beating board 550 and the second bag beating board 650, and the bag beating can be driven by the reciprocating movement of the bag beating cylinders. Those skilled in the art can design and select according to actual needs, and this embodiment does not make any specific limitations on this.

[0151] With this structural design, the cross-section of the bag-beating board is "L"-shaped, which can not only beat and sort the packaging bags, but also act as a stopper to prevent the sorted packaging bags from separating forward into the bag sorting space.

[0152] The implementation of this embodiment also discloses a bag sorting device for packaging bags, which also includes a base adjustment mechanism 700 for adjusting the bag dropping base 100. The base adjustment mechanism 700 is transmission-connected to the bag dropping base 100, and the base adjustment mechanism 700 can drive the bag dropping base 100 to adjust along the bag dropping direction of the packaging bags.

[0153] First of all, it should be noted that the pedestal adjusting mechanism 700 is set to adjust the relative height of the bag dropping pedestal 100, and the height can be adjusted according to the size of different packaging bags or the specific working environment. Further, those skilled in the art can also add a horizontal adjusting mechanism for adjusting the position of the bag dropping pedestal 100 along the horizontal direction without creative labor. The horizontal adjusting mechanism can be, for example, a manual adjusting method with a horizontal slide rail, a horizontal slider, and a locking component.

The locking component can control the switching of the horizontal slider between the locked state and the sliding state, and can be manually slid and adjusted when in the sliding state. The horizontal adjusting mechanism can also be set as a horizontal linear motor, or adjusted and controlled by a driving motor plus a horizontal transmission mechanism. This embodiment does not make specific limitations on this.

[0154] Further, in order to improve the stability of the pedestal adjusting mechanism 700 when adjusting the bag dropping pedestal 100, a vertically arranged guiding component is also provided on the side of the pedestal adjusting mechanism 700.

[0155] The pedestal adjusting mechanism 700 includes a pedestal adjusting unit 710, a pedestal adjusting cross bar 720, and a pedestal lifting group linked with the pedestal adjusting cross bar 720. The pedestal lifting group is in transmission connection with the bag dropping pedestal 100.

The pedestal adjusting cross bar 720 is linked with the pedestal lifting group and drives the bag dropping pedestal 100 to move and adjust along the bag dropping direction of the packaging bag. By setting the pedestal adjusting mechanism 700 to adjust the height of the bag dropping pedestal 100, different lengths or sizes of packaging bags can be adapted. For example, when the length of the packaging bag is 30 cm, the height difference between the bag dropping pedestal 100 and the bag dropping conveyor belt is between 40 and 50 cm, such as 40 cm, 42 cm, and 50 cm, etc.; when manufacturing a 20-cm packaging bag according to different orders, the height of the bag dropping pedestal 100 needs to be increased so that the height difference is between 30 and 40 cm, such as 30 cm, 35.5 cm, and 40 cm, etc.; when manufacturing a larger 40-cm packaging bag according to different orders, the height of the bag dropping pedestal 100 needs to be increased so that the height difference is between 50 and 60 cm, such as 50 cm, 53 cm, and 60 cm, etc. Only simple examples are given in this embodiment. Those skilled in the art can design and adjust according to actual needs. This embodiment does not make specific limitations on this.

[0156] More specifically, the pedestal lifting group in this application can be, for example, a gear-rack mechanism, a worm and worm gear mechanism, a guide rail and slider mechanism, etc., as long as it can realize the up and down adjustment of the bag dropping pedestal 100 along the vertical direction. The pedestal adjusting unit 710 is preferably set as a driving motor, which has the advantages of high driving power and timely response.

[0157] Further preferably, please refer to Figure 1 , on the pedestal adjusting cross bar 720, a first driving helical gear 721 and a second driving helical gear 722 are arranged at intervals along its length direction. The pedestal lifting group includes a first lifting group and a second lifting group respectively adapted to the first driving helical gear 721 and the second driving helical gear 722; wherein

[0158] The first lifting group includes a first driven helical gear 730, a first lead screw 740, and a first lead screw nut 750. The first driven helical gear 730 is fixedly arranged at the end of the first lead screw 740 and is in driving engagement with the first driving helical gear 721. The first lead screw nut 750 is fixedly connected to the bag dropping pedestal 100. The first driving helical gear 721 is in driving engagement with the first driven helical gear 730 and drives the first lead screw 740 to rotate. The first lead screw 740 can drive the first lead screw nut 750 and the bag dropping pedestal 100 to reciprocate along the length direction of the first lead screw 740. It should be noted that two pairs of mutually meshing and cooperating driving teeth and driven teeth are provided to change the output direction of the driving motor.

[0159] The second lifting group includes a second driven helical gear 760, a second lead screw 770, and a second lead screw nut 780. The second driven helical gear 760 is fixedly arranged at the end of the second lead screw 770 and is in driving engagement with the second driving helical gear 722.

The second lead screw 770 can drive the second lead screw nut 780 and the bag dropping pedestal 100 to reciprocate along the length direction of the second lead screw 770.

[0160] With the design of the above structure, by setting a pedestal adjusting cross bar 720 to simultaneously match and control the first lifting group and the second lifting group, the synchronous actions of the first lifting group and the second lifting group can also be realized. The first lifting group and the second lifting group move up and down synchronously, which can stably control the rise or fall of the bag dropping pedestal 100, and the up and down adjustment is carried out through the lead screw mechanism, which has the advantages of high adjustment accuracy and high stability.

[0161] It further includes a fixed profiling frame. The fixed profiling frame is arranged above the bag dropping platform 110, and a through hole for the packaging bag to pass through is opened on the fixed profiling frame.

[0162] In summary, the present utility model provides a bag arranging device. A bag arranging space is formed inside the bag arranging device, and through the mutual cooperation of the bag dropping pedestal 100, the bag pushing mechanism 200, the upper bag blocking mechanism 300, and the lower bag blocking mechanism 400, every time a packaging bag drops, the bag pushing mechanism 200 pushes and arranges it once inside the bag arranging space. And when a predetermined number of packaging bags are arranged inside the bag arranging space, the upper bag blocking member 310 can move in a direction away from the packaging bag and switch from the bag blocking state to the yielding state, thereby leaving a separation space, facilitating the departure of the predetermined number of packaging bags from the bag arranging device, and providing convenience for subsequent packaging or other steps. It has multiple advantages such as improving production efficiency, enhancing product quality, reducing labor intensity and risks, saving costs, and being environmentally friendly and green.

[0163] Furthermore, the upper bag blocking mechanism 300 and the lower bag blocking mechanism 400 can move along the bag dropping direction to achieve the switching between the bag blocking state and the yielding state, and are driven by setting an air pump, having the advantages of simple structure and working mode, low cost, stable operation, precise control, high flexibility and adaptability, and being efficient and reliable.

[0164] Furthermore, a detachable and adjustable first limiting block 130 and a second limiting block 140 are also arranged on the bag dropping platform 110, which are adapted to the bottom bag side of the packaging bag, can assist in limiting the packaging bag, prevent the phenomenon of the packaging bag from tilting, and the first bag patting group 500 and the second bag patting group 600 on both sides of the bag arranging space can conveniently and timely pat the two side parts of the packaging bag, making the packaging bag neater during bag arranging, and performing all-round limiting, protection, and arrangement on the packaging bag during bag arranging.

[0165] In the bag arranging device disclosed by the present utility model, the bag pushing drive assembly 210 includes two sets of transmission groups arranged on both sides of the bag pushing plate 240 and running synchronously, having the advantages of high efficiency and stability during transmission. The pedestal adjusting mechanism 700 is provided to adjust the height of the bag dropping pedestal 100, so as to adapt to packaging bags of different lengths or different sizes.

[0166] Finally, a brief description is given to the working principle and working process of the bag arranging device for the packaging bags disclosed in this application:

[0167] Specifically, the bag arranging device of the packaging bag mainly includes a bag dropping pedestal 100, a pedestal adjusting mechanism 700, a bag pushing mechanism 200, an upper bag blocking mechanism 300, a lower bag blocking mechanism 400, and a side bag patting assembly. The pedestal adjusting mechanism 700 can adjust the relative height of the bag dropping pedestal 100. The bag dropping pedestal 100 is provided with a bag dropping platform 110 for receiving the packaging bag. The packaging bag drops onto the bag dropping platform 110 along the bag dropping direction. A bag arranging space is formed between the upper bag blocking member 310 and the bag pushing mechanism 200 for the bag pushing assembly to reciprocate along the bag arranging direction. The bag pushing mechanism 200 can reciprocate along the bag arranging direction of the packaging bag and push the packaging bag after the packaging bag drops. And the side bag patting assembly can perform bag patting treatment in an intermittent working mode after pushing the bag. When a predetermined number of packaging bags drop into the bag arranging space, the upper bag blocking member 310 moves away from the packaging bag along the bag dropping direction and switches from the bag blocking state to the yielding state. The upper bag blocking member 310 is separated from the packaging bag, and the packaging bag is pushed and separated or grabbed and separated by a manipulator and then undergoes subsequent packing steps.

[0168] Further, taking the length dimension of the packaging bag to be arranged as 30 cm and the predetermined number of bags arranged at one time as 15 as an example for illustration. Before the bag arranging starts, first adjust the bag dropping pedestal 100 within a suitable height range according to the volume and size of the packaging bag. For example, adjust the interval between the bag dropping pedestal 100 and the bag dropping conveyor belt to be 50 cm. When the packaging bag drops onto the bag dropping platform 110 along the bag dropping direction, the upper bag blocking member 310 and the lower bag blocking member 420 are in the bag blocking state. When the bag pushing mechanism 200 starts to push and work, the bag pushing drive motor drives the transmission rod 213 to rotate and drives the first transmission group and the second transmission group to reciprocate. The first transmission group and the second transmission group respectively drive the first moving group 218 and the second moving group 219 to reciprocate, and drive the bag pushing assembly to reciprocate along the bag arranging direction of the packaging bag. The reciprocating movement distance of the bag pushing assembly can be a stroke of 15 cm. For example, at this time, the bag pushing assembly first pushes the first packaging bag to move to the side close to the upper bag blocking member 310 in the bag arranging space and is limited by the upper bag blocking member 310 and the lower bag blocking member 420. Then, the second, third, and Nth packaging bags start to drop in sequence. Each time a packaging bag drops, the bag pushing assembly pushes and arranges it once. And while the bag pushing assembly pushes a packaging bag, the first bag patting group 500 and the second bag patting group 600 on the side of the packaging bag perform bag patting treatment on the side of the packaging bag, so that the side flatness of the arranged packaging bag is better. While arranging the bags, the gripping manipulator for gripping the packaging bag waits on one side of the upper bag blocking member 310 and the lower bag blocking member 420. The packaging bag continues to drop and is pushed and arranged. Each time a packaging bag drops, the counting component adds and counts once. When the bag pushing reaches the predetermined number, for example, when it reaches 15, the upper bag blocking member 310 and the lower bag blocking member 420 move and yield. At this time, the packaging bag is grabbed by the gripping manipulator and moved to the packing mechanism for packing.
