Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, and in particular to a strapping tape offset packaging method and packaging machine. Background Technology

[0002] Currently, with the continuous development of the logistics industry, goods are typically packaged using strapping machines before transportation. During the packaging process, the strapping machine feeds the strapping around the goods once, then tightens it to secure it to the surface of the goods. Finally, the strapping is welded and cut. For certain special goods (such as photovoltaic glass), corner protectors are needed at the corners for protection during packaging. These corner protectors are then simultaneously strapped to the goods using strapping. For example, Chinese Patent Publication No. CN 113443235 A discloses a packaging device and its control method with automatic corner protector feeding function. After placing corner protectors on the surface of the goods, they are then strapped together using strapping.

[0003] Due to limitations such as the position of the straps on the bottom of the pallet, the distance between the straps and the end face of the goods is relatively large during actual packing. This necessitates the use of longer corner protectors to meet the binding requirements, thus increasing packing costs. Furthermore, during packing, the straps are prone to getting caught on the edges of the corner protectors, leading to straps detaching and reducing packing quality. Therefore, designing a packing technology that reduces packing costs and improves packing quality is the technical problem this invention aims to solve. Summary of the Invention

[0004] This invention provides a strapping method and a strapping machine with offset strapping, which shortens the overall length of the corner protectors, thereby reducing the packaging cost and reducing the occurrence of strapping tape falling off the corner protectors, thus improving the quality of strapping.

[0005] This invention provides a method for offset packaging with strapping, comprising: a strapping head driving a strapping band to be conveyed in a packaging chute so that the strapping band surrounds the goods; the strapping head pulling the strapping band so that the strapping band is disengaged from the packaging chute; the strapping head and the goods moving relative to each other so that the strapping bands on both sides of the strapping head are arranged at an angle relative to the adjacent packaging chute; and finally, the strapping head moving close to the surface of the goods and tightening the strapping band before welding and cutting the strapping band.

[0006] Furthermore, the relative movement between the strapping head and the goods specifically includes:

[0007] After the strapping head pulls the strapping tape out of the packaging chute, the strapping head moves relative to the goods so that the strapping tape on both sides of the strapping head is deflected.

[0008] Alternatively, after the strapping head pulls the strapping tape out of the packaging chute, the goods move relative to the strapping head so that the strapping tape on both sides of the strapping head is deflected.

[0009] Furthermore, the packaging chute includes a first chute and two second chutes, the first chute and the strapping head are arranged opposite to each other, the two second chutes are arranged on both sides of the strapping head, the first chute can reciprocate relative to the two second chutes, and the first chute is configured to be inserted into the pallet of the goods.

[0010] The packaging method is as follows: First, the first strapping groove extends and inserts into the pallet, forming a feeding channel for conveying the strapping tape between the strapping head, the second strapping groove, and the first strapping groove; then, the strapping head drives the strapping tape to be conveyed in the packaging chute so that the strapping tape surrounds the goods; next, the strapping head pulls the strapping tape to disengage it from the packaging chute, and after the strapping tape disengages from the packaging chute, the first strapping groove retracts to leave the pallet; the strapping head moves relative to the goods so that the strapping tape on both sides of the strapping head is partially offset relative to the adjacent packaging chute; finally, the strapping head moves closer to the surface of the goods and tightens the strapping tape before welding and cutting it.

[0011] The present invention also provides a packing machine for implementing the above-described offset packing method of strapping, comprising:

[0012] A frame, wherein a packaging chute is provided on the frame, the packaging chute forming a feeding channel for conveying strapping tape;

[0013] A strapping head, the strapping head being configured to drive strapping tape to be conveyed in the tape feeding channel and to strap the strapping tape to the surface of the goods;

[0014] An offset drive mechanism is configured to drive a relative offset movement between the strapping head and the goods after the strapping head pulls the strapping tape out of the packaging chute, such that a portion of the strapping tape is deflected off the corresponding portion of the packaging chute.

[0015] Furthermore, the packaging chute includes a first belt groove and two second belt grooves, the first belt groove and the strapping head are arranged opposite to each other, and the strapping head can be close to or away from the first belt groove; the strapping head is located between the two second belt grooves;

[0016] When the strapping head is feeding strapping tape, the second tape groove is connected between the strapping head and the first tape groove;

[0017] The second groove is configured to be obliquely arranged relative to the strapping on the surface of the cargo.

[0018] Furthermore, the packaging chute also includes a blocking member disposed on one side of the second chute, the blocking member being configured to prevent the strapping pulled out from the second chute from abutting against the surface of the goods.

[0019] Furthermore, the offset drive mechanism is configured to move the strapping head; or, the offset drive mechanism is configured to move the frame.

[0020] Furthermore, the offset drive mechanism is configured to move the cargo.

[0021] During the strapping and packaging process, after the strapping head has completed the conveying and pre-tensioning of the strapping tape, it will offset relative to the goods. This causes the pre-tensioned strapping tape on the goods to be skewed, and the strapping head relative to the goods is closer to the edge of the goods. Then, the strapping head tightens the strapping tape as it gets closer to the goods, allowing the strapping tape to be tied even closer to the edge of the goods. This effectively shortens the overall length of the corner protector and reduces packaging costs. At the same time, because the strapping tape detached from the strapping head is closer to the edge of the goods, it ensures that the strapping tape is tightened in the middle of the corner protector while shortening the corner protector, reducing the possibility of the strapping tape falling off the corner protector and thus improving the quality of strapping.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] Example 1: This invention provides a method for offset packaging with strapping, comprising: a strapping head driving a strapping band to be conveyed in a packaging chute so that the strapping band surrounds the goods; the strapping head pulling the strapping band so that the strapping band is disengaged from the packaging chute; the strapping head and the goods moving relative to each other so that the strapping bands on both sides of the strapping head are arranged at an angle relative to the adjacent packaging chute; finally, the strapping head moving close to the surface of the goods and tightening the strapping band before welding and cutting the strapping band.

[0033] Specifically, in the actual packaging process, the goods are transported to the packaging area of ​​the packaging machine so that the packaging machine can process the goods. The packaging machine usually includes a strapping head and a packaging chute. The two work together to complete operations such as conveying, tightening, welding and cutting of the strapping, so that the strapping can be tightened on the surface of the goods.

[0034] When corner protectors are needed to protect the edges of goods, tightening the straps close to the edges of the goods can ensure they are effectively secured to the corner protectors even when the corners are shortened, thus improving packaging quality and reducing costs. Therefore, when using the above packaging method to pack the corners of goods where corner protectors are needed, an offset packing method should be employed.

[0035] Specifically, the strapping tape, driven by the strapping machine head, will wrap around the outside of the goods under the guidance of the packaging chute. At this time, the strapping tape is conveyed in the same way as conventional strapping tape.

[0036] After the strapping has been conveyed and circled the goods once, the strapping head moves to pull the strapping, causing it to disengage from the packaging chute. At this point, the strapping is pre-tensioned and the strapping head is a certain distance from the goods. In this state, the portion of the strapping away from the strapping head will be tightly secured to the goods.

[0037] After the strapping tape is released from the packaging chute, in order to meet the requirements of offset packaging, the strapping head and the goods will move relative to each other, so that the strapping head and the strapping tape tightened on the surface of the goods will be misaligned. At this time, the strapping tape on both sides of the strapping head will tilt, so that the strapping tape on both sides of the strapping head is skewed relative to the groove of the packaging chute on the adjacent side.

[0038] After the strapping head completes its offset movement, it can move towards the surface of the goods, bringing it close to the surface. The strapping head will also tighten the strapping tape, ensuring that the strapping tape on both sides of the strapping head is in contact with the surface of the goods. Finally, the strapping head will weld and cut the strapping tape.

[0039] Ultimately, regarding the strapping straps attached to the surface of the goods, the strapping straps detached from the strapping head (i.e., the head section) will tighten the corner guards and be closer to the edge of the goods, while the strapping straps away from the strapping head (i.e., the opposite section of the head) will be arranged in a staggered parallel manner with the head section. The strapping straps on both sides of the strapping head (i.e., the inclined connecting sections) will be attached to the surface of the goods and connected between the head section and the opposite section of the head in an inclined manner.

[0040] Compared to conventional strapping and packaging methods, conventional strapping straps typically require the straps to be perpendicular to the edges of the goods to achieve the desired binding effect. The packaging method in this application, however, refers to... Figure 1 As shown, for the strapping a in the middle of the goods, the conventional strapping method is used, meaning there is no relative offset between the strapping head and the goods during the strapping and packaging process. However, when strapping the corners of the goods where corner protectors are placed, a method is used where the strapping head and the goods are offset. This allows the strapping b to be closer to the edge of the goods, and after the strapping b is tightened on the corner protector, the friction between the strapping b and the corner protector, and even the indentation caused by the strapping b squeezing the corner protector, will prevent the strapping b from moving relative to the corner protector. This offset strapping ensures that the strapping b maintains good binding restraint after the offset strapping.

[0041] During the bundling process, after the bundling head has completed the conveying and pre-tensioning of the strapping tape, it will offset relative to the goods. This causes the pre-tensioned strapping tape on the goods to be skewed, and the part of the bundling head relative to the goods to be closer to the edge of the goods. Then, the bundling head tightens the strapping tape as it gets closer to the goods, allowing the strapping tape to be tied even closer to the edge of the goods. This effectively shortens the overall length of the corner protector. At the same time, because the strapping tape detached from the bundling head is closer to the edge of the goods, it ensures that the strapping tape is tightened in the middle of the corner protector while shortening it, reducing the possibility of the strapping tape falling off the corner protector and thus improving the quality of bundling.

[0042] Furthermore, in the actual packing process, in order to achieve a relative offset between the goods and the strapping head, the relative movement between the strapping head and the goods is specifically as follows:

[0043] After the strapping head pulls the strapping tape out of the packaging chute, the strapping head moves relative to the goods so that the strapping tape on both sides of the strapping head is deflected.

[0044] Alternatively, after the strapping head pulls the strapping tape out of the packaging chute, the goods move relative to the strapping head so that the strapping tape on both sides of the strapping head is deflected.

[0045] Specifically, in the actual strapping and packaging process, after the strapping tape is pulled out of the packaging chute, in order to meet the requirements of offset packaging, a corresponding offset needs to be created between the strapping head and the goods, so that the strapping tape located between the strapping head and the goods is deflected. To achieve this, the strapping head can be offset outwards relative to the goods while the goods remain stationary; or, the goods can be offset outwards relative to the strapping head while the strapping head remains stationary.

[0046] In some embodiments, the strapping can be conveyed via an arrow-like method for the packaging chute 2; therefore, refer to... Figure 1 As shown, the packaging chute 2 includes a first chute 21 and two second chute 22. The first chute 21 is arranged opposite to the strapping head 3, and the two second chute 22 are arranged on both sides of the strapping head 3. The first chute 21 can reciprocate relative to the two second chute 22. The first chute 21 is configured to be inserted into the pallet 101 of the goods 100.

[0047] The packaging method is as follows: First, the first strapping groove 21 moves out to insert into the pallet 101, forming a strapping feeding channel between the strapping head 3, the second strapping groove 22, and the first strapping groove 21 for conveying the strapping; then, the strapping head 3 drives the strapping to be conveyed in the packaging chute 2 so that the strapping surrounds the goods 100; next, the strapping head 3 pulls the strapping to disengage it from the packaging chute 2, and after the strapping is disengaged from the packaging chute 2, the first strapping groove 21 moves back to leave the pallet 101; the strapping head 3 moves relative to the goods 100 so that the strapping on both sides of the strapping head 3 is partially offset relative to the adjacent packaging chute 2; finally, the strapping head 3 moves closer to the surface of the goods 100 and tightens the strapping before welding and cutting the strapping.

[0048] Specifically, during the strapping and packaging process, when it is necessary to convey strapping tape around the goods 100, the first tape groove 21 moves to connect between the two second tape grooves 22. At this time, a tape feeding channel for conveying the strapping tape is formed between the strapping head 3, the second tape grooves 22, and the first tape groove 21. Driven by the strapping head 3, the strapping tape will be guided around the goods 100 once by the tape feeding channel.

[0049] After the strapping is fed, the strapping head 3 moves, causing the strapping to disengage from the first strapping groove 21 and the second strapping groove 22. The portion of the strapping that has disengaged from the first strapping groove 21 will be pressed against the surface of the goods 100. At this time, the first strapping groove 21 can be retracted to ensure that when there is a relative offset between the strapping head 3 and the goods 100, the first strapping groove 21 will not interfere with the pallet 101 on which the goods 100 is mounted.

[0050] Furthermore, after the first strapping groove 21 retracts, the strapping head 3 and the cargo 100 move relative to each other, causing the strapping straps on both sides of the strapping head 3 to deflect, and then the subsequent packaging operation steps are performed.

[0051] Example 2, as Figures 1-3 As shown, this application also provides a strapping machine for offset strapping, the strapping machine comprising:

[0052] A frame 1 is provided with a packaging chute 2, which forms a feeding channel for conveying strapping tape.

[0053] Strapping head 3, the strapping head 3 being configured to drive strapping tape to be conveyed in the tape feeding channel and to strapping tape to the surface of cargo 100;

[0054] The offset drive mechanism 4 is configured to drive the strapping head 3 and the goods 100 to move relative to each other after the strapping head 3 pulls the strapping tape out of the packaging chute 2, so that a portion of the strapping tape is deflected from the corresponding portion of the packaging chute 2.

[0055] Specifically, the strapping head 3 and the packaging chute 2 are mounted on the frame 1. The strapping head 3 has the functions of conveying strapping tape, tightening strapping tape, welding and cutting strapping tape. The specific structural form of the strapping head 3 can refer to the head structure of conventional strapping machines, and will not be limited or elaborated here. The packaging chute 2 is used to guide the strapping tape to be conveyed around the goods 100. Similarly, the specific structure of the packaging chute 2 can refer to the grooved structure in conventional technology, and will not be limited or elaborated here.

[0056] When corner protectors are needed to protect the edges of goods 100, tightening the strapping close to the edge of goods 100 can ensure that the strapping is effectively tightened on the corner protectors even when the corners are shortened, thereby improving packaging quality and reducing packaging costs. Therefore, in addition to meeting conventional packaging requirements, the aforementioned strapping machine is equipped with an offset drive mechanism 4 to meet the requirements of offset packaging. This offset drive mechanism 4 causes a relative offset movement between the strapping head 3 and the goods 100 after the strapping head 3 pulls the strapping from the packaging chute 2 and before the strapping head 3 is pressed against the surface of the goods 100.

[0057] Specifically, after the strapping head 3 pulls the strapping tape out of the packaging chute 2, the offset drive mechanism 4 actuates to cause a relative offset movement between the strapping head 3 and the goods 100. At this time, the strapping tapes located on both sides of the strapping head 3 will tilt and deflect. At this point, the strapping head 3 is closer to the outer side of the goods 100 than in the feeding state. After the strapping head 3 moves closer to the surface of the goods 100, the strapping tape in the strapping head 3 can get closer to the edge of the goods 100. Furthermore, during the process of the strapping head 3 tightening the strapping tape, the strapping tape can get even closer to the edge of the goods 100 to press the corner protectors firmly against the surface of the goods 100.

[0058] Finally, regarding the strapping straps attached to the surface of the cargo 100, the strapping straps detached from the strapping head 3 (i.e., the head section) will tighten the corner guards and be closer to the edge of the cargo 100, while the strapping straps away from the strapping head 3 (i.e., the opposite section of the head) will be arranged in a staggered parallel manner with the head section. The strapping straps on both sides of the strapping head 3 (i.e., the inclined connecting sections) will be attached to the surface of the cargo 100 and connected between the head section and the opposite section of the head in an inclined manner.

[0059] Compared to conventional strapping and packaging methods, conventional strapping straps typically require the straps to be perpendicular to the edges of the goods to achieve the desired binding effect. The packaging method in this application, however, refers to... Figure 1 As shown, for the strapping a in the middle of the goods 100, the conventional strapping method is used, meaning that there is no relative offset between the strapping head 3 and the goods 100 during the strapping and packaging process. However, when strapping the corners of the goods 100 where corner protectors are placed, a method is used where there is a relative offset between the strapping head 3 and the goods 100. This allows the strapping b to be closer to the edge of the goods 100, and after the strapping b is tightened on the corner protector, the friction between the strapping b and the corner protector, or even the indentation caused by the strapping b squeezing the corner protector, will prevent the strapping b from moving relative to the corner protector. This ensures that the strapping b maintains good binding restraint after offset strapping.

[0060] During the bundling and packaging process, after the bundling head 3 completes the conveying and pre-tensioning of the bundling tape, it will offset relative to the goods 100. This causes the pre-tensioned bundling tape on the goods 100 to be skewed, and the part of the bundling head 3 relative to the goods 100 to be closer to the edge of the goods 100. Then, the bundling head 3 tightens the bundling tape as it approaches the goods 100, which allows the bundling tape to be tied closer to the edge of the goods 100. This effectively shortens the overall length of the corner protector. At the same time, because the bundling tape detached from the bundling head 3 can be closer to the edge of the goods 100, it ensures that the bundling tape can be tightened in the middle of the corner protector while shortening the corner protector, thereby reducing the possibility of the bundling tape falling off the corner protector and improving the bundling quality.

[0061] Furthermore, the offset drive mechanism 4 can drive the cargo 100 to move, or it can drive the strapping head 3 or the frame 1 to move. Therefore, the specific physical manifestation of the offset drive mechanism 4 can have various structural forms.

[0062] In structural form one, the offset drive mechanism 4 is used to drive the strapping head 3 to move. Specifically, as shown... Figure 2 and Figure 3 As shown, the offset drive mechanism 4 can be a cylinder or electric actuator mounted on the frame 1. Besides being able to move closer to or further away from the goods 100, the strapping head 3 can also be driven to offset relative to the goods 100 via the offset drive mechanism 4. For this purpose, a sliding frame 43 is mounted on the frame 1, which can move closer to or further away from the goods 100. Furthermore, a sliding seat 44 is also provided on the sliding frame 43. The strapping head 3 is mounted on the sliding seat 44. The offset drive mechanism 4 can drive the sliding seat 44 to slide on the sliding frame 43. The sliding frame 43 can move the strapping head 3 closer to or further away from the goods 100, while the sliding seat 44 can move the strapping head 3 to offset relative to the goods 100.

[0063] In the second structural configuration, the offset drive mechanism 4 is used to drive the frame 1 to move as a whole, thereby causing the strapping head 3 to offset relative to the cargo 100 via the frame 1. Specifically, as shown... Figure 1 As shown, the frame 1 is equipped with a slide rail 41, and the frame 1 can slide on the slide rail 41. The offset drive mechanism 4 may include a motor and a gear, and the slide rail 41 is equipped with a rack 42. The gear can rotate on the frame 1. The motor drives the gear to rotate so that the gear and the rack 42 cooperate to drive the frame 1 to slide on the slide rail 41.

[0064] In the third structural form, the offset drive mechanism 4 is used to drive the movement of the goods 100. Specifically, the offset drive mechanism 4 can be a conveyor line located at the frame 1. The conveyor line can transport the goods 100 to the frame 1 so that the goods 100 is located in the packaging area where the strapping head 3 is located. The conveyor line can also drive the goods 100 to move during the strapping process as needed to meet the requirement of offset of the goods 100 relative to the strapping head 3.

[0065] Furthermore, the packaging chute 2 includes a first chute 21 and two second chute 22. The first chute 21 and the strapping head 3 are arranged opposite to each other, and the strapping head 3 can be close to or away from the first chute 21. The strapping head 3 is located between the two second chute 22.

[0066] When the strapping head 3 is conveying strapping tape, the second tape groove 22 is connected between the strapping head 3 and the first tape groove 21;

[0067] The second groove 22 is configured to be obliquely arranged relative to the strapping on the surface corresponding to the cargo 100.

[0068] Specifically, the first groove 21 in the packaging chute 2 can move relative to the second groove 22 on the frame 1, thereby meeting the requirements for threading the strap. In this way, when the goods 100 are equipped with components such as a pallet 101, the first groove 21 can be used to feed the strap into the pallet 101, ensuring that the strapping can be conveyed through the pallet 101.

[0069] During the strapping and packaging process, when it is necessary to convey the strapping strap, the first strap groove 21 extends and inserts into the pallet 101, simultaneously connecting between the two second strap grooves 22 to meet the requirements for conveying the strapping strap. When offset is required, the first strap groove 21 can be retracted first, so that when the goods 100 and the strapping head 3 are offset relative to each other, the first strap groove 21 will not interfere with the pallet 101 on which the goods 100 are configured.

[0070] Specifically, for at least a portion of the strapping that has detached from the second groove 22, after the cargo 100 and the strapping head 3 are relatively offset, this portion of the strapping will be arranged at an angle relative to the second groove 22 on the corresponding side.

[0071] In another embodiment, the packaging chute 2 further includes a blocking member 23 disposed on one side of the second chute 22, the blocking member 23 being configured to prevent the strapping pulled out from the second chute 22 from abutting against the surface of the goods 100.

[0072] Specifically, when the strapping tape needs to be offset after being pulled out of the packaging chute 2, the strapping tape pulled out of the packaging chute 2 and located on both sides of the strapping head 3 will be supported by the blocking component 23 so that when the goods 100 and the strapping head 3 are offset relative to each other, the strapping tape on both sides of the strapping head 3 will not scratch the surface of the goods 100.

[0073] The offset drive mechanism 4 is also configured to drive the strapping head 3 and the cargo 100 to move relative to each other, so that the strapping tape falls off the blocking member 23 and abuts against the surface of the cargo 100.

[0074] In some embodiments, in order to ensure that the blocking member 23 does not obstruct the normal pre-tensioning operation of the strapping during normal packaging, the blocking member 23 may be movable relative to the second strap groove 22.

[0075] Specifically, during normal strapping and packaging, the blocking component 23 will avoid the second strap groove 22, allowing the strapping tape to be pulled out of the second strap groove 22 and directly abut against the surface of the goods 100. When offset strapping is required, the blocking component 23 will block the second strap groove 22 so that the strapping tape can be blocked by the blocking component 23 during pre-tensioning. After the relative offset between the strapping head 3 and the goods 100 is completed, the blocking component 23 can be activated to release the strapping tape. That is, the blocking component 23 is configured to block one side of the second strap groove 22 when the strapping head 3 pulls the strapping tape out of the second strap groove 22, and the blocking component 23 is also configured to move away from the second strap groove 22 to release the strapping tape when the offset drive mechanism 4 drives the strapping head 3 and the goods 100 to move relative to each other.
