Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to a strapping device and method for stacked palletized materials. Background Technology

[0002] Currently, the packaging of palletized materials generally employs vertical or horizontal strapping. Two pallets of already packaged material, mounted on pallets, are stacked one on top of the other and secured with strapping tape to form a single unit. The strapping tape typically binds the top and bottom surfaces of the palletized material or passes through the upper and lower pallets, binding the pallets and the lower palletized material together. This type of packaging and strapping is planar and parallel, resulting in the material being tightened in only one direction. Furthermore, the strapping tapes are not interconnected, leaving the palletized material at risk of displacement, deformation, or even tipping over during transport.

[0003] To improve the stability and reliability of bundling and packaging stacked materials, the following methods are typically used: Figure 1 The binding method shown is used to bind stacked materials. Figure 1 This is a schematic diagram of an existing method for bundling stacked materials. This bundling method uses bundling straps 10 to bind two sets of diagonal corners on one side of the upper material 11 and the lower material 12's pallet. This ensures that the stacked materials are tightly bound in multiple dimensions, preventing displacement and deformation. Currently, this bundling method mostly relies on manual labor, resulting in low efficiency and wasted manpower. Summary of the Invention

[0004] The purpose of this invention is to provide a bundling device for stacked materials, so as to solve the problem of low work efficiency in the prior art when bundling stacked materials manually; in addition, another purpose of this invention is to provide a bundling method based on the bundling device for stacked materials.

[0005] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0006] In a first aspect, the present invention provides a strapping device for stacked materials, comprising a first threading slot device, a second threading slot device, a head device, and a relay device, wherein:

[0007] Stacked materials include upper layer materials and lower layer materials;

[0008] The first threading groove device includes a first threading groove assembly, which is movable into or out of the first pier corner. The first threading groove assembly is configured to form a first threading channel that bypasses the first pier corner after being moved into the first pier corner.

[0009] The second threading groove device includes a second threading groove assembly, which is movable into or out of the second pier corner. The second threading groove assembly is configured to form a second threading channel that bypasses the second pier corner after being moved into the second pier corner.

[0010] The first corner is one of the corners of the upper layer pallet and the second corner is one of the corners of the lower layer pallet, or the first corner is one of the corners of the lower layer pallet and the second corner is one of the corners of the upper layer pallet.

[0011] Both the machine head assembly and the relay assembly can be moved to either the first or second corner of the pier;

[0012] When the machine head device and the relay device move to the first corner of the pier, the machine head device is configured to feed the tape to the first tape threading channel, the relay device is configured to receive and fix the end of the strapping tape in the first tape threading channel, and the machine head device is also configured to retract the tape after the relay device receives and fixes the end of the strapping tape in the first tape threading channel, so that the strapping tape is detached from the first tape threading channel and goes around the first corner of the pier.

[0013] During the process of the head unit and the relay unit moving from the first corner to the second corner, the head unit is configured to perform belt feeding;

[0014] When the head assembly and the relay assembly move to the second corner, the relay assembly is configured to feed the receiving and securing strapping into the second strapping channel, and the head assembly is configured to receive and secure the end of the strapping in the second strapping channel.

[0015] After the head unit receives and secures the end of the strapping tape in the second threading channel, the head unit or relay unit is configured to take up the tape, causing the strapping tape to detach from the second threading channel and pass around the second corner. The head unit is also configured to tighten, weld, and cut the strapping tape that has passed around the first and second corners, so as to bind the first and second corners together with the strapping tape.

[0016] Optionally, after the strapping tape detaches from the second threading channel and passes around the second corner, the machine head device is configured to move to a preset position between the first and second corners and then tighten, weld, and cut the strapping tape that has passed around the first and second corners.

[0017] Optionally, the relay device includes a mounting base, a driving wheel mechanism, and a driven wheel mechanism, wherein: the mounting base has a conveying channel extending along the conveying direction of the strapping tape;

[0018] The drive wheel mechanism includes a first drive member and a drive wheel. The fixed end of the first drive member is mounted on the mounting base, and the drive end of the first drive member is connected to the drive wheel. The drive wheel is rotatably mounted on the mounting base and located on the first side of the conveying channel. The first drive member is configured to drive the drive wheel to rotate in the forward or reverse direction.

[0019] The driven wheel mechanism includes a second drive member and a driven wheel assembly. The fixed end of the second drive member is mounted on a mounting base. The driven wheel assembly includes a driven wheel, which is disposed on the second side of the conveying channel corresponding to the drive wheel. The driven wheel is rotatable and can be mounted on the mounting base close to or away from the drive wheel.

[0020] When the second driving member drives the driven wheel to move to the first position, the driving wheel cooperates with the driven wheel to clamp and fix the strapping in the conveying channel; or the first driving member drives the driving wheel to rotate in the forward direction to cooperate with the driven wheel to feed the strapping in the conveying channel into the second threading channel; or the first driving member drives the driving wheel to rotate in the reverse direction to cooperate with the driven wheel to retract the strapping in the second threading channel, so that the strapping is released from the second threading channel and goes around the second corner.

[0021] When the second driving member drives the driven wheel to the second position, the distance between the driven wheel and the driving wheel increases, allowing the strapping to detach from the conveyor channel.

[0022] Optionally, the mounting base closes the downward side of the conveying channel and opens the upward side of the conveying channel. The relay device also includes a movable baffle, which is set above the driven wheel. The movable baffle can be installed on the mounting base horizontally close to or away from the driving wheel. The drive end of the second drive unit is connected to the movable baffle.

[0023] The second driving component drives the movable baffle to move horizontally toward the drive wheel to close the upward side of the conveyor channel, so as to prevent the strapping inside the conveyor channel from coming off.

[0024] The second drive unit drives the movable baffle to move horizontally away from the drive wheel to open the upward side of the conveyor channel, so that the strapping can be detached from the conveyor channel.

[0025] Optionally, the second driving component includes a first cylinder and a connecting component. The end of the drive rod of the first cylinder is connected to the first end of the connecting component, and the second end of the connecting component is connected to a movable baffle.

The first end of the wheel frame is hinged to the mounting base by a pin, and the second end of the wheel frame is set corresponding to the drive rod of the first cylinder. The driven wheel is rotatably mounted in the middle of the wheel frame.

[0026] While the first cylinder drives the movable baffle to move horizontally closer to the driving wheel, the driving rod of the first cylinder abuts against the second end of the wheel frame to drive the driven wheel to move closer to the driving wheel to the first position.

[0027] The first end of the first elastic element is connected to the wheel frame, and the second end of the first elastic element is connected to the mounting base. After the drive rod of the first cylinder leaves the second end of the wheel frame, the wheel frame is reset by the first elastic element so that the driven wheel moves away from the driving wheel to the second position.

[0028] Optionally, the relay device also includes a detection device, which is located at the rear of the drive wheel and the driven wheel along the conveying direction of the strapping. The detection device is configured to detect whether the strapping in the conveying channel has moved to a preset position.

The lifting frame is movably mounted on the movable frame. The fixed end of the first lifting drive unit is mounted on the movable frame, and the drive end of the first lifting drive unit is connected to the lifting frame. The first lifting drive unit is configured to drive the lifting frame to move up and down.

[0030] The first and second threading devices are mounted on the movable frame. The first threading device is positioned above the second threading device. The lifting frame is positioned between the first and second threading devices. The machine head device and the relay device are mounted on the lifting frame.

[0031] Optionally, the first threading slot device further includes a first mounting frame, a first lateral movement drive, a second lateral movement drive, and a first lateral movement seat. The first mounting frame is mounted on a movable frame. The first lateral movement seat is reciprocally mounted on the first mounting frame in a first horizontal direction. The first threading slot assembly is movably mounted on the first lateral movement seat in a second horizontal direction. The first lateral movement drive is configured to drive the first threading slot assembly to reciprocate in the second horizontal direction. The second lateral movement drive is configured to drive the first lateral movement seat to reciprocate in the first horizontal direction, thereby moving the first threading slot assembly into or out of the first pier corner. The first threading slot assembly has a first movable threading slot that can be opened or closed. When the first movable threading slot is open, it avoids the first threading slot assembly moving into or out of the first pier corner. After the first threading slot assembly moves into the first pier corner, the first movable threading slot is closed, thereby forming a first threading channel that bypasses the first pier corner at the first pier corner.

[0032] The second threading slot device further includes a second mounting frame, a third lateral movement drive, a fourth lateral movement drive, and a second lateral movement seat. The second mounting frame is mounted on a movable frame. The second lateral movement seat is reciprocally mounted on the second mounting frame in a first horizontal direction.

The fourth lateral movement drive is configured to drive the second lateral movement seat to reciprocate in the first horizontal direction, thereby moving the second threading slot assembly into or out of the second pier corner. The second threading slot assembly has a second movable threading slot that can be opened or closed. When the second movable threading slot is open, it avoids the second threading slot assembly moving into or out of the second pier corner. After the second threading slot assembly moves into the second pier corner, the second movable threading slot closes, thereby forming a second threading channel that bypasses the second pier corner.

[0033] Optionally, the head assembly includes a rotating frame, a strapping head, a rotating drive, and a fifth lateral drive. The rotating frame is rotatably mounted on a lifting frame, and the strapping head is movable on the rotating frame along a first horizontal direction. The fifth lateral drive is configured to drive the strapping head to reciprocate along the first horizontal direction to approach or move away from the strapping surface of the material. The rotating drive is configured to drive the rotating frame to rotate by a preset angle to rotate the strapping head to a position consistent with the strapping angle of the strapping tape.

[0034] Optionally, the rotating frame is also provided with a flipping drive, a transverse movement and a sixth transverse movement drive. The fixed end of the flipping drive is mounted on the transverse movement, and the transverse movement is mounted on the rotating frame in a reciprocating manner along the second horizontal direction. The relay device is flipped and hinged to the transverse movement, and the driving end of the flipping drive is connected to the relay device. The flipping drive is configured to drive the relay device to flip to the third or fourth position.

[0035] When the flipping drive unit drives the relay device to flip to the third position, the relay device extends out of the binding surface of the binding head to cooperate with the head device, the first threading slot device and the second threading slot device.

[0036] When the flipping drive unit drives the relay device to flip to the fourth position, the relay device flips to a position in the first horizontal direction that avoids the strapping head, so that the strapping head can strap the first corner and the second corner;

[0037] The fixed end of the sixth transverse drive is mounted on the rotating frame, and the drive end of the sixth transverse drive is connected to the transverse member. The sixth transverse drive is configured to drive the transverse member to reciprocate along the second horizontal direction.

During the process of the head device and the relay device moving from the third corner to the fourth corner, the relay device fixes the end of the strapping that has detached from the second strapping channel, and the head device feeds the strapping.

[0053] The relay device supplies strapping to the first threading channel, and the machine head device receives and secures the end of the strapping in the first threading channel;

[0054] The machine head device or relay device performs the take-up operation, causing the strapping to detach from the first threading channel and go around the fourth corner of the block;

[0055] The machine head device will tighten, weld, and cut the strapping tape around the third and fourth corners to bind the third and fourth corners, thus completing the binding of one side of the upper and lower material pallets.

[0056] Optionally, after the strapping tape detaches from the second strapping channel and passes around the second corner, the machine head device moves to a preset position between the first and second corners and then tightens, welds, and cuts the strapping tape that has passed around the first and second corners.

[0057] After the strapping tape detaches from the first threading channel and passes around the fourth corner, the machine head device moves to a preset position between the third and fourth corners and then tightens, welds, and cuts the strapping tape that has passed around the third and fourth corners.

[0084] Please see Figures 1 to 3As shown, this embodiment provides a strapping device for stacked materials, including a first threading groove device 20, a second threading groove device 30, a machine head device 40, and a relay device 50. The stacked materials include an upper layer of material 11 and a lower layer of material 12. The first threading groove device 20 includes a first threading groove assembly 21, which is movable into or out of a first corner. The first threading groove assembly 21 is configured to form a first threading channel bypassing the first corner after being moved into it. The second threading groove device 30 includes a second threading groove assembly 31. The second threading groove assembly 31 can be moved into or out of the second corner. The second threading groove assembly 31 is configured to form a second threading channel bypassing the second corner after being moved into the second corner. The first corner is one of the corners of the pallet of the upper material 11 and the second corner is one of the corners of the pallet of the lower material 12, or the first corner is one of the corners of the pallet of the lower material 12 and the second corner is one of the corners of the pallet of the upper material 11. Both the machine head device 40 and the relay device 50 can be moved to the first corner or the second corner. When the relay device 50 moves to the first corner of the pier, the head unit 40 is configured to feed the belt into the first belt threading channel, and the relay device 50 is configured to receive and secure the end of the strapping tape in the first belt threading channel. The head unit 40 is also configured to retract the belt after the relay device 50 receives and secures the end of the strapping tape in the first belt threading channel, causing the strapping tape to detach from the first belt threading channel and pass around the first corner of the pier. During the process of the head unit 40 and the relay device 50 moving from the first corner of the pier to the second corner of the pier, the head unit 40 is configured to feed the belt. At the second corner, the relay device is configured to feed the received and fixed strapping into the second strapping channel, and the head device 40 is configured to receive and fix the end of the strapping in the second strapping channel; after the head device 40 receives and fixes the end of the strapping in the second strapping channel, the head device 40 or the relay device 50 is configured to retract the strapping, so that the strapping is released from the second strapping channel and passes around the second corner. The head device is also configured to tighten, weld and cut the strapping that passes around the first and second corners, so as to bind the first and second corners with the strapping.

[0085] Through the cooperation of the first strapping slot device 20, the second strapping slot device 30, the machine head device 40 and the relay device 50, the automatic strapping of the strapping tape around the first corner and the second corner in multiple dimensions is realized. No manual intervention is required, the work efficiency is high, manpower is saved, the strapping cost can be reduced to a certain extent, and the strapping quality and effect can be guaranteed.

[0086] In one implementation, after the strapping tape detaches from the second threading channel and passes around the second corner, the machine head device 40 is configured to move to a preset position between the first and second corners and then tighten, weld, and cut the strapping tape that has passed around the first and second corners.

[0087] By moving the head unit 40 to a preset position between the first and second corners, the binding tape that passes around the first and second corners is tightened, welded, and cut. This allows the head unit 40 to be moved to a convenient binding position or a preset binding position, facilitating the binding process and improving binding efficiency.

[0088] Please refer to 2 to Figure 7 As shown, in one embodiment, the relay device 50 includes a mounting base 51, a driving wheel mechanism 52, and a driven wheel mechanism 53, wherein: the mounting base 51 has a conveying channel 510 extending along the conveying direction of the strapping; the driving wheel mechanism 52 includes a first driving member 520 and a driving wheel 521, the fixed end of the first driving member 520 is mounted on the mounting base 51, and the driving end of the first driving member 520 is connected to the driving wheel 521, the driving wheel 521 is rotatably mounted on the mounting base 51 and located on the first side of the conveying channel 510, and the first driving member 520 is configured to drive the driving wheel 521 to rotate in the forward or reverse direction; the driven wheel mechanism 53 includes a second driving member 530 and a driven wheel assembly, the fixed end of the second driving member 530 is mounted on the mounting base 51, and the driven wheel assembly includes a driven wheel 531, the driven wheel 531 is disposed on the second side of the conveying channel 510 corresponding to the driving wheel 521, and the driven wheel 531 is rotatable. The second drive member 530 is mounted on the mounting base 51 near or away from the drive wheel 521. The second drive member 530 is configured to drive the driven wheel 531 to a first position or a second position. When the second drive member 530 drives the driven wheel 531 to the first position, the drive wheel 521 and the driven wheel 531 cooperate to clamp and fix the strapping in the conveying channel 510. Alternatively, the first drive member 520 drives the drive wheel 521 to rotate in the forward direction to cooperate with the driven wheel 531 to feed the strapping in the conveying channel 510 into the second threading channel. Alternatively, the first drive member 520 drives the drive wheel 521 to rotate in the reverse direction to cooperate with the driven wheel 531 to retract the strapping in the second threading channel, so that the strapping is detached from the second threading channel and passes around the second corner. When the second drive member 530 drives the driven wheel 531 to the second position, the distance between the driven wheel 531 and the drive wheel 521 increases, so that the strapping can be detached from the conveying channel 510.

[0089] Specifically, the first drive unit 520 uses a servo motor.

[0090] Through the cooperation of the driving wheel mechanism 52 and the driven wheel mechanism 53, the functions of clamping and fixing, feeding and taking back the strapping in the conveying channel 510 are realized, providing a relay device 50 with a compact structure, ingenious design and high integration.

[0091] In one embodiment, the mounting base 51 closes the downward-facing side of the conveying channel 510 and opens the upward-facing side of the conveying channel 510. The relay device 50 also includes a movable baffle 54, which is disposed above the driven wheel 531. The movable baffle 54 can be mounted on the mounting base 51 in a horizontal direction, approaching or moving away from the driving wheel 521. The driving end of the second driving member 530 is connected to the movable baffle 54. The second driving member 530 drives the movable baffle 54 to move in a horizontal direction towards the driving wheel 521 to close the upward-facing side of the conveying channel 510, so as to prevent the strapping tape in the conveying channel 510 from coming off the conveying channel 510. The second driving member 530 drives the movable baffle 54 to move in a horizontal direction away from the driving wheel 521 to open the upward-facing side of the conveying channel 510, so as to facilitate the strapping tape coming off the conveying channel 510.

[0092] Specifically, the movable baffle 54 is mounted on the mounting base 51 via a first guide member 540 consisting of a slider and a linear guide rail and a second guide member 541 consisting of a wheel frame and a guide wheel, in order to ensure the stability and reliability of the movement of the movable baffle 54.

[0093] By setting the movable baffle 54, the upward-facing side of the conveying channel 510 can be automatically closed or opened as needed. At the same time, the movement of the driven wheel 531 and the movable baffle 54 share a single drive component, which simplifies the overall structure, reduces manufacturing costs, and makes the layout more reasonable and compact.

[0094] In one embodiment, the second driving member 530 includes a first cylinder 5300 and a connecting member 5301.
