Description

Technical Field

[0001] The present invention relates to the technical field of diaper production, in particular to a diaper packaging bag, automatic packaging equipment and an automatic packaging method. Background Art

[0002] Diapers, also known as wet diapers, are an indispensable daily necessity in the process of raising infants and young children. In the prior art, diaper products are usually packaged in bags. In a packaging bag, dozens of diapers are stacked together, squeezed and deformed against each other to increase the packaging capacity of each packaging bag. In order to avoid damaging the skin of infants and young children, diapers are usually processed into suede on the surface, which leads to great friction between two adjacent diapers. When taking diapers, it is easy to take out multiple diapers at a time due to the friction between diapers, and even cause some diapers to fall to the ground and be contaminated, and it is also time-consuming and laborious to sort out the extra diapers.

[0003] A Chinese patent document with the announcement number CN214139640U discloses a sterilization packaging bag for diapers, which includes a packaging bag body, an isolation layer integrally formed on the inner surface of the packaging bag body, a score line on the side surface of the packaging bag body, a tear strip bonded and fixed on the surface of the packaging bag body located on the score line, and the upper end of the tear strip exceeds the outside of the packaging bag body, a pull ring is provided on the upper end of the packaging bag body, a rubber bottom plate is bonded to the lower surface of the packaging bag body, an anti-slip strip is integrally formed on the lower surface of the rubber bottom plate, and a buffer cavity is provided on the upper surface of the rubber bottom plate. In this document, by integrally forming multiple isolation layers inside the packaging bag body to achieve isolation of adjacent diapers, the effect of avoiding taking out multiple diapers at one time can be achieved.

[0004] However, this solution still has shortcomings, mainly manifested in the following aspects: (1) It is very difficult to form the packaging bag body and the isolation layer in one piece. The current mature plastic bag processing technology mainly involves blowing the film first, then bending the plastic film into shape and hot pressing it to form a plastic bag. There are many isolation layers in this solution, and there are also many connection points with the plastic bag body, which cannot be processed using mature existing processes; (2) The material of conventional diaper packaging bags is relatively soft. Even if the isolation layer is processed in one piece through high-cost means, the space between the two isolation layers is very unstable. It is easy for the deformation of the isolation layer to cause this part of the space to deform or be closed. Therefore, it is difficult to load the diapers into the space between the two isolation layers. If the hardness of the isolation layer and the packaging bag body is increased, the entire diaper packaging product will be inconvenient to transport. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the present invention provides a diaper packaging bag, an automatic packaging device and an automatic packaging method, wherein a diaphragm is added between two adjacent diapers to separate the two adjacent diapers through the diaphragm to avoid excessive friction between the two diapers causing other adjacent diapers to be brought out when taking out the diaper.

[0012] When the auxiliary tooling moves to the bottom of the end of the first conveyor, the moving assembly passes through the passage to the top of the top plate, and a first slot capable of accommodating the diaphragm is formed between two adjacent moving assemblies;

[0013] When the auxiliary tooling moves to the bottom of the end of the second conveyor, the positioning plate is located above the top plate and the lifting block is flush with the top plate, and a second slot capable of accommodating the diaper is formed between the two positioning plates in the moving assembly.

[0014] Preferably, the automatic packaging equipment also includes two connecting rods, one of which is fixedly connected to all the positioning plates, and the other is fixedly connected to all the lifting blocks, and each of the two connecting rods is connected to a lifting driver for driving the connecting rod to rise and fall.

[0015] Preferably, the lifting block and the positioning plate are both provided with inclined surfaces, and when the auxiliary tooling moves below the end of the first conveyor, a guide groove for guiding the diaphragm to move toward the first slot is formed between two adjacent inclined surfaces.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figures 1 to 5 As shown, a diaper packaging bag includes a bag body 1, and the bag body 1 includes two oppositely arranged side portions 2, and one of the side portions 2 is provided with a press seam 3 for assisting in tearing the bag body 1. The bag body 1 also includes a front side portion and a rear side portion parallel to each other, and the two side portions 2 are located between the front side portion and the rear side portion, and the front side portion, the rear side portion and the two side portions 2 together enclose a total volume for accommodating diapers 6. A plurality of mutually parallel diaphragms 4 are arranged inside the bag body 1, and the diaphragms 4 are perpendicular to the side portions 2, and the hardness of the diaphragms 4 is higher than that of the bag body 1, and a first accommodating space 5 for accommodating diapers 6 is formed between two adjacent diaphragms 4, and all diaphragms 4 are connected by at least one connecting piece 9, and the connecting piece 9 is in contact with the inner wall of the bag body 1.

[0044] In the packaging bag of the present invention, one of the two side portions 2 of the bag body 1 is selected to be provided with a press seam 3. When taking out the diaper 6, the bag body 1 can be opened with the help of the press seam 3 by pulling the two sides of the press seam 3. After the bag body 1 is opened, the diaper 6 can be taken out, because there are diaphragms 4 on both sides of each diaper 6, that is, the diaper 6 is located in the first accommodating space 5 between two adjacent diapers 4, so the diapers 6 will not contact each other. When taking out the diaper 6, multiple diapers 6 will not be taken out at the same time due to excessive friction between two adjacent diapers 6, which can prevent the diaper 6 from falling and being contaminated by the diaper 6. On the other hand, the connecting piece 9 is connected to all the diaphragms 4, and can limit all the diaphragms 4 to avoid the diaphragms 4 being misplaced, resulting in the loss of the effect of preventing the diapers 6 from rubbing against each other, resulting in the removal of other diapers 6 when one diaper 6 is taken out.

[0045] The diaper packaging bag of the present invention adds a diaphragm 4 between two adjacent diapers 6, and separates the two adjacent diapers 6 through the diaphragm 4, so as to avoid excessive friction between the two diapers 6, which may cause other adjacent diapers 6 to be taken out when the diapers 6 are taken out, and to avoid contamination of the diapers 6 by taking out too many diapers 6 at one time. Obviously, the surface of the diaphragm 4 should be smooth to fully reduce the friction between the diaphragm 4 and the diapers 6. In practical applications, the diaphragm 4 can be made of polyethylene film and have a certain hardness to avoid contamination of the diapers 6 and ensure that the diaphragm 4 has a certain anti-deformation ability.

[0046] Considering that the total volume of the bag body 1 is generally a rectangular cavity, and the diaper 6 is also generally rectangular after compression, the diaphragm 4 can also be rectangular, and the two short sides of the diaphragm 4 are respectively close to the two side portions 2 of the bag body 1, and an extension portion 7 is integrally connected to both ends of one of the short sides of the diaphragm 4, and a through hole 8 is provided on the extension portion 7, and the connecting piece 9 can pass through the through hole 8. There are two connecting pieces 9, and the two connecting pieces 9 connect all the diaphragms 4 from the sides of the two long sides of the diaphragm 4, respectively, so that the position of all the diaphragms 4 can be ensured to be stable.

[0047] Furthermore, after the connecting piece 9 passes through the through hole 8, the extension portion 7 can be bent and attached to the connecting piece 9 to form a connecting portion 10, and a second accommodating space 11 capable of accommodating an adhesive block 12 is formed between two adjacent connecting portions 10. The adhesive block 12 is used to adhere and fix the connecting piece 9 to the inner wall of the bag body 1. Through the adhesive block 12, the two connecting pieces 9 can be adhered and fixed to the front side and the rear side of the bag body 1, respectively, so as to further stabilize the position of the diaphragm 4 and prevent the diaphragm 4 from being deflected or shifted. The adhesive block 12 can be selected in a suitable form according to actual needs. For example, the adhesive block 12 can be set as a Velcro, and the two parts of the Velcro are respectively fixed on the connecting piece 9 and the front side or the rear side. The adhesive can also be coated on the second accommodating space 11, and the adhesive forms the adhesive block 12 after the adhesive dries. At this time, the connecting part 10 can constrain the adhesive in the second accommodating space 11 to ensure that the connecting piece 9 can be bonded and fixed to the front side or the rear side from multiple different points, thereby improving the stability of the position of the connecting piece 9 and the connection strength with the front side or the rear side. Obviously, because the packaging bag of the present invention contains diapers 6, if an adhesive is used to bond and fix the connecting piece 9 to the front side or the rear side, the adhesive should be non-toxic, and a suitable adhesive material can be selected according to actual needs. In addition, the connecting piece 9 can also be fixedly connected to the front side or the rear side by hot pressing, and the position of the hot pressing connection is also located in the second accommodating space 11.

[0048] In the present invention, the diaphragm 4, the connecting sheet 9 and the bag body 1 are manufactured separately, and the conventional manufacturing process of plastic sheets and plastic bags can be adopted, which is mature and low-cost. After the diaphragm 4 and the connecting sheet 9 are manufactured separately, they are assembled. After the assembly, a first accommodating space 5 for accommodating diapers 6 is formed between two adjacent diaphragms 4. At this time, the diapers can be loaded into the first accommodating space 5. Because the hardness of the diaphragm 4 is higher than the hardness of the bag body 1, when the diapers are loaded into the first accommodating space 5, the shape of the first accommodating space 5 is relatively stable, and it is easier to load the diapers. Then put the diaphragm 4, connecting piece 9 and diaper into the bag body 1 as a whole. Because the bag body 1 is relatively soft, the diaphragm 4, connecting piece 9 and diaper can be put into the bag body 1 by simply opening the bag body 1 for a short time. There is no need to keep opening the bag body 1. This is simpler and easier than putting diapers into the bag body 1 one by one. Finally, the connecting piece 9 is connected to the bag body 1 to complete the packaging process.

[0049] As shown in Figure 6 to Fig.11As shown, the present invention further provides an automatic packaging device for loading diapers into the above-mentioned diaper packaging bag, the automatic packaging device includes a first conveyor 23 for conveying the diaphragm 4, a second conveyor 24 for conveying the diapers 6, and a movable auxiliary tooling, which can pass under the ends of the first conveyor 23 and the second conveyor 24 during the movement.

[0050] The auxiliary tooling includes a top plate 17 and a bottom plate 21 arranged up and down, a plurality of channels 22 are opened on the top plate 17, a plurality of moving components are arranged between the top plate 17 and the bottom plate 21 for lifting and lowering, and the moving components can pass through the channels 22 accordingly during the lifting process, and the moving components include two parallel positioning plates 16 and a lifting block 13 located between the two positioning plates 16.

[0051] When the auxiliary tooling moves to below the end of the first conveyor 23 , the moving assembly passes through the passage 22 to reach above the top plate 17 , and a first slot capable of accommodating the diaphragm 4 is formed between two adjacent moving assemblies.

[0052] When the auxiliary tooling moves to the bottom of the end of the second conveyor 24, the positioning plate 16 is located above the top plate 17 and the lifting block 13 is flush with the top plate 17, and a second slot capable of accommodating the diaper 6 is formed between the two positioning plates 16 in the moving assembly.

[0053] When using the automatic packaging equipment to load the diapers 6 into the packaging bag of the present invention, first move the auxiliary tooling to the bottom of the end of the first conveyor 23, and at this time all the moving components are located above the top plate 17, then allow the diaphragm 4 transported by the first conveyor 23 to fall downward into the first slot, and continue to move the auxiliary tooling so that all the first slots contain the diaphragm 4. At this time, the two extensions 7 of the diaphragm 4 fall directly on the top plate 17, so that the diaphragm 4 can fall on the top plate 17, and the moving components are used to support the diaphragm 4 to prevent the diaphragm 4 from falling on the top plate 17. Then, the connecting piece 9 is passed through all the through holes 8 on the extension part 7 in sequence. Since the diaphragm 4 itself has a certain hardness, the connecting piece 9 can be easily passed through all the through holes 8. Specifically, the connecting piece 9 can be driven through the through hole 8 by a mechanical arm, or the connecting piece 9 can be manually passed through the through hole 8. When the connecting piece 9 is driven through the through hole 8 by a mechanical arm, a guide plate for guiding the direction of the connecting piece 9 can be added to the auxiliary tooling, and a guide groove is provided on the guide plate. After the diaphragm 4 is inserted into all the first slots, the guide plate is located on the side of the moving component. The connecting piece 9 is placed into the guide groove by a mechanical arm and driven to move along the guide groove, so that the connecting piece 9 can pass through the through hole 8 smoothly. The structure of the guide plate and the guide groove is simple and is not shown in the figure. In order to ensure that the connecting piece 9 can pass through the through hole 8 smoothly, the length and width of the through hole 8 can be slightly larger than the length and width of the cross-section of the connecting piece 9. Afterwards, the auxiliary tooling is moved to the bottom of the end of the second conveyor 24, and all the lifting blocks 13 are driven to move downward synchronously until the top of the lifting block 13 is flush with the upper surface of the top plate 17, and the positioning plate 16 continues to prevent the diaphragm 4 from falling onto the top plate 17; then the diaper 6 conveyed by the second conveyor 24 can fall downward into the second slot formed between the two positioning plates 16 in a moving assembly, and is lifted by the lifting block 13 in the moving assembly to avoid falling directly between the top plate 17 and the bottom plate 21. After the diapers 6 are inserted into all the second slots, all the positioning plates 16 are moved downward until the top of the positioning plates 16 is also flush with the upper surface of the top plate 17, and at this time there is a diaper 6 between any two adjacent diaphragms 4, and the diaphragms 4 and the diapers 6 are both located on the top plate 17, and the positioning plates 16 and the lifting blocks 13 are staggered from the diaphragms 4 and the diapers 6. Subsequently, all the diapers 6 and the diaphragm 4 are bundled together with a strapping tape or a strapping line to form a preparatory package, and the preparatory package is transferred to the bag body 1. Finally, all the diapers 6 and the diaphragm 4 are transferred to the total volume of the bag body 1, and the strapping tape or the strapping line is removed and the bag is sealed. The transfer, bagging and bag sealing are all conventional techniques in the art, and conventional devices can be selected to cooperate with the automatic packaging equipment of the present invention, which will not be described in detail here.It should also be noted that, according to the selected method of forming the bonding block 12, in the bagging process, corresponding materials can be pre-arranged at corresponding positions of the connecting piece 9 and the bag body 1. For example, when the bonding block 12 is formed by using an adhesive, the adhesive can be applied to multiple positions on the connecting piece 9 by using a dispensing machine, and then the preparatory package is placed in the bag body 1 and the bag body 1 is squeezed so that the adhesive can bond the connecting piece 9 and the bag body 1 together. The dispensing machine is a mature existing technology and will not be described in detail here.

[0054] Because the lifting block 13 and the positioning plate 16 need to move separately, and all the lifting blocks 13 need to keep synchronization during the action, similarly all the positioning plates 16 also need to keep synchronization during the action. In order to achieve this effect, the automatic packaging equipment also includes two connecting rods 19, one of which is fixedly connected to all the positioning plates 16, and the other is fixedly connected to all the lifting blocks 13. The two connecting rods 19 are each connected to a lifting driver 20 for driving the lifting of the connecting rod 19. It should also be noted that both connecting rods 19 should be located on the side of the moving component, that is, the connecting rod 19 cannot hinder the movement of the lifting block 13 and the positioning plate 16. By controlling the two lifting drivers 20 separately, all the lifting blocks 13 and all the positioning plates 16 can be driven separately, and the control is simpler. In the present invention, the lifting driver 20 can adopt a conventional linear driver such as a cylinder or an electric push rod, which will not be repeated here.

[0055] In order to ensure that the diaphragm 4 can smoothly fall from the first conveyor 23 into the first slot, the lifting block 13 and the positioning plate 16 are both provided with inclined surfaces 14. When the auxiliary tooling moves to the bottom of the end of the first conveyor 23, a guide groove 15 for guiding the diaphragm 4 to move toward the first slot is formed between two adjacent inclined surfaces 14. Because the movement trajectory of the lower end of the diaphragm 4 is a parabola as a whole when it falls downward from the end of the first conveyor 23, it will first be installed on the inclined surface 14, and then under the guidance of the inclined surface 14, it will move to the middle of the guide groove 15. The middle of the guide groove 15 is aligned with the first slot, so it can smoothly enter the first slot, avoiding the situation where part of the diaphragm 4 is missing. On this basis, an arc plate can also be set at the lower side of the end of the first conveyor 23. The arc plate is used to limit the range of movement of the diaphragm 4 during the falling process, further ensuring that the diaphragm 4 can smoothly enter the first slot. In addition, two mutually parallel limiting plates can be arranged on the first conveyor 23, and the diaphragm 4 passes between the two limiting plates on the first conveyor 23 and contacts both limiting plates, so that the moving direction of the diaphragm 4 is controlled by the two limiting plates, further ensuring that the diaphragm 4 can smoothly fall downward into the first slot. The second conveyor 24 can be arranged in a similar manner to the first conveyor 23, so that the diaper 6 can smoothly fall into the second slot.

[0056] Furthermore, the top plate 17 and the bottom plate 21 are fixedly connected by a plurality of support rods 18, and all the support rods 18 enclose an action space, and the moving components are all located in the action space. The support rods 18 need to be arranged on the sides of the top plate 17 and the bottom plate 21 to avoid obstruction to the movement of the moving components.

[0057] Furthermore, the automatic packaging equipment further comprises a third conveyor 25, which is located below the first conveyor 23 and the second conveyor 24, and is used to convey auxiliary tooling. In the present invention, the first conveyor 23, the second conveyor 24 and the third conveyor 25 can all be conventional belt conveyors.

[0058] The present invention also provides an automatic packaging method, which is based on the above-mentioned automatic packaging equipment and includes the following steps.

[0059] S1: driving the auxiliary tooling to move to the lower part of the end of the first conveyor 23. A plurality of positioning protrusions evenly distributed along the transport direction may be provided on the third conveyor 25, and at least two positioning grooves may be provided on the lower surface of the bottom plate 21. By using the cooperation of the two positioning protrusions and the positioning grooves, the position of the auxiliary tooling on the third conveyor 25 may be conveniently determined, ensuring that the auxiliary tooling can be stably moved to the lower part of the end of the first conveyor 23.

[0060] S2: driving all the moving components to move to the top of the top plate 17, so that a first slot is formed between two adjacent moving components. Specifically, two lifting actuators 20 are used to drive all the positioning plates 16 and all the lifting blocks 13 to move to the top of the top plate 17, so as to form a first slot for accommodating the diaphragm 4.

[0061] S3: Use the first conveyor 23 to convey the diaphragms 4 so that the diaphragms 4 fall into the first slots one by one. It should be noted that the first conveyor 23 and the third conveyor 25 need to be in continuous operation, and the conveying speed of the third conveyor 25 needs to be determined according to the conveying speed of the first conveyor 23, so that the diaphragms 4 can be inserted into the first slots one by one.

[0062] S4: driving the auxiliary tooling to move to below the end of the second conveyor 24 .

[0063] S5: Drive the lifting blocks 13 in all the moving components to move downward to be flush with the top plate 17, so that a second slot is formed between two positioning plates 16 in one moving component.

[0064] S6: The diapers 6 are conveyed by the second conveyor 24 so that the diapers 6 fall into the second slots one by one.

[0065] S7: drive all moving components to move downward to below the top plate 17, so that the diaphragm 4 and the diaper 6 stay on the top plate 17. At this time, the diaphragm 4 falls directly on the top plate 17 with the help of the extension part 7, and the diaper 6 is lifted by the lifting block 13.

[0066] In actual implementation, in order to improve production efficiency, the first conveyor 23 and the second conveyor 24 are in continuous operation. Accordingly, multiple auxiliary tools are simultaneously conveyed on the third conveyor 25, so that while a certain auxiliary tool receives the diaphragm 4 from below the end of the first conveyor 23, another auxiliary tool receives the diaper 6 from below the end of the second conveyor 24. The end below the first conveyor 23 is called the first station, and the end below the second conveyor 24 is called the second station. In the process of transferring from the first station to the second station, the auxiliary tool drives all the lifting blocks 13 to descend to the level of their upper ends with the top plate 17 by the lifting drive 20, so as to lift the diaper 6 dropped into the second slot at the second station.

[0067] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0068] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
