Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to an actuator and a strapping device for bundling 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.

[0004] Therefore, there is an urgent need in the market for a method applicable to stacked materials such as... Figure 1 Strapping equipment that implements automated strapping. Existing strapping equipment can only perform vertical or horizontal planar strapping on stacked materials, while... Figure 1 The binding structure shown requires the binding strap to go around the two corners of the support before binding. The actuator of the existing binding equipment cannot automatically bind stacked materials in multiple dimensions. Summary of the Invention

[0005] The purpose of this invention is to provide an actuator for bundling stacked materials, so as to solve the problem that the actuator of the bundling equipment in the prior art cannot perform multi-dimensional bundling of stacked materials; in addition, another purpose of this invention is to provide a bundling device including the actuator for bundling stacked materials.

[0006] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0007] In a first aspect, the present invention provides an actuator for bundling stacked materials, comprising a head assembly and a relay assembly, wherein:

[0008] The relay device is installed on the head unit. The relay device and the head unit can move synchronously to the first or second corner. The first corner is one of the corners of the upper material pallet and the second corner is one of the corners of the lower material pallet, or the first corner is one of the corners of the lower material pallet and the second corner is one of the corners of the upper material pallet.

[0009] 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 belt to the first belt-threading channel surrounding the first corner of the pier, the relay device is configured to receive and fix the end of the strapping belt in the first belt-threading channel, and the machine head device is also configured to retract the belt after the relay device receives and fixes the end of the strapping belt in the first belt-threading channel, so that the strapping belt is detached from the first belt-threading channel and goes around the first corner of the pier.

[0010] 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;

[0011] When the head unit and the relay unit move synchronously to the second corner of the pier, the relay unit is configured to send the received and fixed strapping into the second strapping channel surrounding the second corner of the pier, and the head unit is configured to receive and fix the end of the strapping in the second strapping channel.

[0012] 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.

[0013] Optionally, after the strapping tape detaches from the second threading channel and passes around the second corner, the head unit and the relay unit are configured to move synchronously to a first preset position in the middle part of the strapping surface of the corresponding lower material. The relay unit avoids the head unit, and the head unit tightens, welds, and cuts the strapping tape that passes around the first and second corners. The projection of the first preset position on the strapping surface of the lower material is located between the first and second corners.

[0014] Optionally, the head unit is also configured to rotate at a preset angle at a first preset position, so that the head unit rotates to a position consistent with the strapping angle.

[0015] Optionally, the head assembly includes a base, a rotating frame, a strapping head, a rotating drive, and a first lateral drive. The rotating frame is rotatably mounted on the base, and the strapping head is movable along a first horizontal direction on the rotating frame. The first 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 lower 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.

[0016] Optionally, the rotating frame is also provided with a flipping drive, a lateral movement component, and a second lateral movement drive. The fixed end of the flipping drive is mounted on the lateral movement component, and the lateral movement component is mounted on the rotating frame in a reciprocating manner along the second horizontal direction. The relay device is flipped and hinged to the lateral movement component. 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 a first position or a second position, and the first horizontal direction is perpendicular to the second horizontal direction.

[0017] When the flipping drive unit drives the relay device to flip to the first position, the relay device extends out of the strapping surface of the strapping machine head;

[0018] When the flipping drive unit drives the relay device to flip to the second 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;

[0019] The fixed end of the second transverse drive is mounted on the rotating frame, and the drive end of the second transverse drive is connected to the transverse member. The second transverse drive is configured to drive the transverse member to reciprocate along the second horizontal direction.

[0020] Optionally, the relay device includes a mounting base, a driving wheel mechanism, and a driven wheel mechanism, wherein:

[0021] The mounting base has a conveying channel extending along a second horizontal direction, and the mounting base is mounted on the transverse moving member;

[0022] 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.

[0023] The driven wheel mechanism includes a second driving member and a driven wheel assembly. The fixed end of the second driving member is mounted on the mounting base. The driven wheel assembly includes a driven wheel, which is disposed on the second side of the conveying channel corresponding to the driving wheel. The driven wheel is rotatable and can be reciprocated on the mounting base along the first horizontal direction. The second driving member is configured to drive the driven wheel to move to a third position or a fourth position.

[0024] When the second driving member drives the driven wheel to move to the third 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 corresponding second threading channel, so that the strapping is released from the second threading channel and goes around the second corner.

[0025] When the second driving component drives the driven wheel to the fourth position, the distance between the driven wheel and the driving wheel increases, allowing the strapping to detach from the conveyor channel.

[0026] 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 located above the driven wheel. The movable baffle can be mounted on the mounting base close to or away from the driving wheel in the first horizontal direction. The drive end of the second drive unit is connected to the movable baffle.

[0027] The second driving component drives the movable baffle to move closer to the drive wheel along the first horizontal direction to close the upward side of the conveying channel, so as to prevent the strapping in the conveying channel from coming off the conveying channel.

[0028] The second drive unit drives the movable baffle to move away from the drive wheel along the first horizontal direction to open the upward side of the conveyor channel so that the strapping can be detached from the conveyor channel.

[0029] 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 driven wheel assembly also includes a wheel frame and a first elastic component. 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.

[0030] While the first cylinder drives the movable baffle to move closer to the driving wheel in the first horizontal direction, 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 third position.

[0031] 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 fourth position.

[0032] Optionally, the relay device also includes a detection device, which is disposed at the rear of the driving wheel and the driven wheel along the second horizontal direction. The detection device is configured to detect whether the strapping in the conveying channel has moved to a preset position.

[0033] Secondly, the present invention also proposes a bundling device for bundling stacked materials, which includes the aforementioned actuator for bundling stacked materials.

[0034] The beneficial effects of the present invention are as follows: Compared with the prior art, the actuator for stacked materials provided by the present invention has the following beneficial effects:

[0035] 1. Through the cooperation of relay device and strapping device, automatic strapping of stacked materials in multiple directions is realized. It has high work efficiency, saves manpower, reduces strapping cost to a certain extent, and ensures strapping quality and effect.

[0056] The present invention will be further described in detail below with reference to the accompanying drawings.

[0057] To facilitate understanding of the present invention, a more complete description of the invention will be given below with reference to the accompanying drawings.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0058] Please see Figure 1 and Figure 2 As shown, this embodiment provides an actuator for bundling stacked materials, including a machine head device 20 and a relay device 30. The stacked materials include an upper layer material 11 and a lower layer material 12. The relay device 30 is installed on the machine head device 20. The relay device 30 and the machine head device 20 can move synchronously to a first corner or a second corner. The first corner is one of the corners of the pallet of the upper layer material 11 and the second corner is one of the corners of the pallet of the lower layer material 12, or the first corner is one of the corners of the pallet of the lower layer material 12 and the second corner is one of the corners of the pallet of the upper layer material 11.

[0059] When the head unit 20 and the relay unit 30 move to the first corner of the pier, the head unit 20 is configured to feed the belt to the first belt-threading channel surrounding the first corner of the pier, and the relay unit 30 is configured to receive and fix the end of the strapping belt in the first belt-threading channel. The head unit 20 is also configured to retract the belt after the relay unit 30 receives and fixes the end of the strapping belt in the first belt-threading channel, so that the strapping belt is detached from the first belt-threading channel and passes around the first corner of the pier.

[0060] During the process of the head unit 20 and the relay unit 30 moving from the first corner to the second corner, the head unit 20 is configured to feed the strapping; when the head unit 20 and the relay unit 30 move synchronously to the second corner, the relay unit 30 is configured to feed the received and fixed strapping into the second strapping channel surrounding the second corner, and the head unit 20 is configured to receive and fix the end of the strapping in the second strapping channel; after the head unit 20 receives and fixes the end of the strapping in the second strapping channel, the head unit 20 or the relay unit 30 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 unit 20 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.

[0061] Through the cooperation of the head unit 20, the relay unit 30, the first strapping channel, and the second strapping channel, automated strapping is achieved by automatically wrapping the strapping tape around the first and second corners in multiple dimensions. This eliminates the need for manual intervention, resulting in high work efficiency, labor savings, and reduced strapping costs to some extent, while ensuring strapping quality and effectiveness. Simultaneously, the relay unit 30, mounted on the head unit 20, enables synchronous movement of both devices. The overall structure is compact and occupies little space, which can shorten the total travel distance of the head unit 20 and the relay unit 30, thus improving strapping efficiency.

[0062] In one implementation, after the strapping tape detaches from the second threading channel and passes around the second corner, the head device 20 and the relay device 30 are configured to move synchronously to a first preset position in the middle part of the strapping surface of the corresponding lower material 12. The relay device 30 avoids the head device 20. The head device 20 tightens, welds and cuts the strapping tape that passes around the first and second corners. The projection of the first preset position on the strapping surface of the lower material 12 is located between the first and second corners.

[0063] By first synchronously moving the head assembly 20 and the relay assembly 30 to the first preset position, and then the relay assembly 30 avoiding the head assembly 20, the head assembly 20 finally tightens, welds, and cuts the strapping tape that has bypassed the first and second corners. This allows the head assembly 20 to move to a convenient or preset strapping position first, facilitating the strapping process and improving strapping efficiency.

[0064] In one embodiment, the head unit 20 is also configured to rotate at a first preset position by a preset angle, so that the head unit 20 rotates to a position consistent with the strapping angle.

[0065] By rotating the head device 20, which is in the first preset position, by a preset angle, the head device 20 can adapt to the binding direction and binding angle of the strapping tape, so as to ensure the binding quality and binding effect.

[0066] Please see Figures 2 to 5 As shown in one embodiment, the head assembly 20 includes a base 21, a rotating frame 22, a strapping head 23, a rotating drive 24, and a first lateral drive 25. The rotating frame 22 is rotatably mounted on the base 21, and the strapping head 23 is movable along a first horizontal direction on the rotating frame 22. The first lateral drive 25 is configured to drive the strapping head 23 to reciprocate along the first horizontal direction to approach or move away from the strapping surface of the lower material 12. The rotating drive 24 is configured to drive the rotating frame 22 to rotate by a preset angle to rotate the strapping head 23 to a position consistent with the strapping angle of the strapping tape.

[0067] Specifically, the rotary drive component 24 includes a rotary motor and a drive gear set, and the rotary motor drives the rotary frame 22 to rotate through the drive gear set.

[0068] Specifically, the first lateral movement drive 25 includes at least one cylinder, with the fixed end of the cylinder connected to the rotating frame 22 and the driving end of the cylinder connected to the strapping head 23.

[0069] The base 21, rotating frame 22, strapping head 23 and rotating drive component 24 cooperate to realize the rotation of strapping head 23; the strapping head 23 and the first transverse drive component 25 cooperate to realize the movement of strapping head 23 towards or away from the strapping surface of the lower material 12; a simple, reasonable layout and stable and reliable head device 20 is provided.

[0070] In one embodiment, the rotating frame 22 is further provided with a flipping drive 26, a lateral movement member 27, and a second lateral movement drive 28. The fixed end of the flipping drive 26 is mounted on the lateral movement member 27, which is reciprocally mounted on the rotating frame 22 along a second horizontal direction. The relay device 30 is flip-hinged onto the lateral movement member 27. The driving end of the flipping drive 26 is connected to the relay device 30. The flipping drive 26 is configured to drive the relay device 30 to flip to a first position or a second position, where the first horizontal direction is perpendicular to the second horizontal direction. When the relay device 30 is flipped to the first position, the relay device 30 extends out of the binding surface of the binding head 23; when the flipping drive 26 drives the relay device 30 to flip to the second position, the relay device 30 flips to a position that avoids the binding head 23 in the first horizontal direction, so that the binding head 23 can bind the first corner and the second corner; the fixed end of the second lateral drive 28 is installed on the rotating frame 22, and the driving end of the second lateral drive 28 is connected to the lateral member 27. The second lateral drive 28 is configured to drive the lateral member 27 to reciprocate along the second horizontal direction.

[0071] Specifically, the first position is located on the side of the strapping surface of the strapping head 23 that is close to the material, and the second position is located below the strapping head 23.

[0072] Specifically, both the tilting drive 26 and the second lateral drive 28 are cylinders.

[0073] By cooperating with the flipping drive 26 and the lateral movement 27, the relay device 30 achieves a flipping function relative to the strapping head 23. When the strapping head 23 is threading at the first and second corners, the relay device 30 flips to the first position, facilitating the connection between the strapping head 23 and the first and second threading channels. When the strapping head 23 is strapping, the relay device 30 flips to the second position, avoiding the strapping head 23 in the first horizontal direction. By cooperating with the second lateral movement drive 28 and the lateral movement 27, the relay device 30 reciprocates in the second horizontal direction, facilitating the connection between the two threading channels that are offset in the second horizontal direction.

[0074] Please see Figures 6 to 10As shown, in one embodiment, the relay device 30 includes a mounting base 31, a driving wheel mechanism 32, and a driven wheel mechanism 33. The mounting base 31 has a conveying channel 310 extending along a second horizontal direction. The driving wheel mechanism 32 includes a first driving member 320 and a driving wheel 321. The fixed end of the first driving member 320 is mounted on the mounting base 31, and the driving end of the first driving member 320 is connected to the driving wheel 321. The driving wheel 321 is rotatably mounted on the mounting base 31 and located on the first side of the conveying channel 310. The first driving member 320 is configured to drive the driving wheel 321 to rotate in the forward or reverse direction. The driven wheel mechanism 33 includes a second driving member 330 and a driven wheel assembly. The fixed end of the second driving member 330 is mounted on the mounting base 31. The driven wheel assembly includes a driven wheel 331, which is disposed on the second side of the conveying channel 310 corresponding to the driving wheel 321. The driven wheel 331 is rotatable and can rotate independently. Mounted on the mounting base 31 near or away from the drive wheel 321, the second drive member 330 is configured to drive the driven wheel 331 to a first position or a second position. When the second drive member 330 drives the driven wheel 331 to the first position, the drive wheel 321 and the driven wheel 331 cooperate to clamp and fix the strapping in the conveying channel 310. Alternatively, the first drive member 320 drives the drive wheel 321 to rotate forward, so that the driven wheel 331 can feed the strapping in the conveying channel 310 into the second threading channel. Alternatively, the first drive member 320 drives the drive wheel 321 to rotate in the reverse direction, so that the driven wheel 331 can 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 330 drives the driven wheel 331 to the second position, the distance between the driven wheel 331 and the drive wheel 321 increases, so that the strapping can be detached from the conveying channel 310.

[0075] Specifically, the first drive component 320 uses a servo motor.

[0076] Through the cooperation of the driving wheel mechanism 32 and the driven wheel mechanism 33, the functions of clamping and fixing, feeding and taking back the strapping in the conveying channel 310 are realized, providing a relay device 30 with a compact structure, ingenious design and high integration.

[0077] In one embodiment, the mounting base 31 closes the downward-facing side of the conveying channel 310 and opens the upward-facing side of the conveying channel 310. The relay device 30 also includes a movable baffle 34, which is disposed above the driven wheel 331. The movable baffle 34 can be mounted on the mounting base 31 in a horizontal direction, approaching or moving away from the driving wheel 321. The driving end of the second driving member 330 is connected to the movable baffle 34. The second driving member 330 drives the movable baffle 34 to move in a horizontal direction towards the driving wheel 321 to close the upward-facing side of the conveying channel 310, so as to prevent the strapping tape in the conveying channel 310 from coming off the conveying channel 310. The second driving member 330 drives the movable baffle 34 to move in a horizontal direction away from the driving wheel 321 to open the upward-facing side of the conveying channel 310, so as to facilitate the strapping tape coming off the conveying channel 310.

[0078] Specifically, the movable baffle 34 is slidably mounted on the mounting base 31 via a guide assembly to ensure the stability and reliability of the movement of the movable baffle 34.

[0079] By setting the movable baffle 34, the upward-facing side of the conveying channel 310 can be automatically closed or opened as needed. At the same time, the movement of the driven wheel 331 and the movable baffle 34 share a single drive component, which simplifies the overall structure, reduces manufacturing costs, and makes the layout more reasonable and compact.

[0080] In one embodiment, the second driving member 330 includes a first cylinder 3300 and a connecting member 3301. The end of the driving rod of the first cylinder 3300 is connected to the first end of the connecting member 3301, and the second end of the connecting member 3301 is connected to the movable baffle 34. The driven wheel assembly also includes a wheel frame 332 and a first elastic member (not shown in the figure). The first end of the wheel frame 332 is hinged to the mounting base 31 by a pin 333, and the second end of the wheel frame 332 is set corresponding to the driving rod of the first cylinder 3300. The driven wheel 331 is rotatably mounted in the middle of the wheel frame 332. While the first cylinder 3300 drives the movable baffle 34 to move horizontally closer to the driving wheel 321, the drive rod of the first cylinder 3300 abuts against the second end of the wheel frame 332 to drive the driven wheel 331 to move closer to the driving wheel 321 to the first position. The first end of the first elastic member is connected to the wheel frame 332, and the second end of the first elastic member is connected to the mounting base 31. After the drive rod of the first cylinder 3300 leaves the second end of the wheel frame 332, the wheel frame 332 is reset by the first elastic member so that the driven wheel 331 moves away from the driving wheel 321 to the second position.

[0081] Specifically, a roller 3302 is rotatably mounted on the end of the drive end of the first cylinder 3300. While the first cylinder 3300 drives the movable baffle 34 to move horizontally toward the drive wheel 321, the roller 3302 at the end of the drive rod of the first cylinder 3300 abuts against the second end of the wheel frame 332 to reduce the friction between the drive rod of the first cylinder 3300 and the second end of the wheel frame 332.
