Description

Technical Field

[0001] This utility model belongs to the technical field of stacking machine, and specifically relates to an automatic stacking and unstacking machine. Background Technology

[0002] To address the collection and stacking of empty pallets (frames, bowls), pallet destabilizing and stacking machines have emerged. Many types of pallet destabilizing and stacking machines are available, suitable for various applications. Utility model patent application number CN201520579539.7 discloses a pallet destabilizing and stacking machine, relating to the field of logistics assembly equipment. The machine frame includes a motor mounting plate and a fixing plate. The motor is fixedly mounted on the motor mounting plate. A slide rail assembly is installed on the frame. A lifting fork assembly is located in the middle of the frame. A bearing limiting sleeve is connected to the lower end of the lifting fork assembly. A thrust ball bearing and a first deep groove ball bearing are installed between the lifting fork assembly and the bearing limiting sleeve. The upper end of the lifting fork assembly passes through the screw top plate and the upper bearing adjustment plate at the upper end of the pallet destabilizing and stacking frame and is fixedly connected to the bearing cover. It uses a hollow shaft motor to drive the ball screw to achieve reciprocating motion, which not only greatly saves labor and space costs, but also improves working stability. The stacking and unstacking of the trays can be carried out at high speed, and it can achieve a self-locking function in the event of a power failure, ensuring the safety of the system. It is suitable for medium-load and high-speed applications.

[0003] However, existing tray destacking machines cannot guarantee that the trays will move into place, which may result in the support mechanism being unable to accurately lift the trays. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide an automatic stacking and unstacking machine that ensures that the material trays are stacked or unstacked in the correct position.

[0005] The technical solution adopted in this utility model is as follows: An automatic tray stacking and unstacking machine includes a frame, a lifting mechanism mounted on the frame, a conveying mechanism for conveying trays connected to the output end of the lifting mechanism, and a rotatable support mechanism for supporting the trays mounted on the frame. The support mechanism is located above the conveying mechanism, and a limiting mechanism for limiting the trays is mounted on the conveying mechanism. When stacking trays, the lifting mechanism drives the conveying mechanism to rise, and the support mechanism rotates to a position where it engages with the edge of the tray on the conveying mechanism. When unstacking trays, the lifting mechanism drives the conveying mechanism to rise, and the support mechanism rotates to a position where it disengages from the edge of the tray, and the tray falls onto the conveying mechanism.

[0006] In this invention, when the material tray is conveyed by the conveying mechanism, the limiting mechanism rotates to a position protruding from the conveying mechanism, thereby blocking and limiting the material tray. At this time, after the lifting mechanism raises the conveying mechanism, the supporting mechanism rotates towards the material tray, and the end of the supporting mechanism can accurately engage with the edge of the material tray, ensuring that the material tray can be accurately lifted. When the next material tray is conveyed into place, the limiting mechanism also limits it, and the two layers of material trays can accurately overlap, ensuring reliable stacking. Similarly, when dismantling the trays, the supporting mechanism first loosens the overlapping material trays, the lifting mechanism lowers the conveying mechanism, and the limiting mechanism can accurately limit the material trays. At this time, when the supporting mechanism rotates towards the material tray, it can accurately engage with the second layer of material trays. In summary, the limiting mechanism of this invention can ensure reliable positioning of the material trays and ensure that the supporting mechanism can accurately support the material trays during the stacking and dismantling processes.

[0007] As a preferred embodiment of this utility model, the lifting mechanism includes a lifting power unit mounted on a frame. The output end of the lifting power unit is connected to a drive shaft, and a drive sprocket is mounted on the drive shaft. A driven sprocket is mounted on the end of the frame away from the lifting power unit. A lifting chain is connected between the drive sprocket and the driven sprocket, and the conveying mechanism is fixed to the lifting chain. Driven by the lifting power unit, the drive shaft rotates, causing the lifting chain to move between the drive sprocket and the driven sprocket. The lifting chain then causes the conveying mechanism to rise or fall, and in conjunction with the action of the support mechanism, to stack or unstack trays.

[0008] In a preferred embodiment of this invention, both ends of the drive shaft are equipped with driving sprockets, and there are two driven sprockets. The two driving sprockets and two driven sprockets are respectively located on both sides of the conveying mechanism, which is fixed between two lifting chains. The two lifting chains synchronously drive the conveying mechanism to rise or fall, ensuring smooth lifting and lowering of the conveying mechanism.

[0009] In a preferred embodiment of this invention, the conveying mechanism includes a conveying frame housed within a machine frame and fixed to the output end of a lifting mechanism. A conveying drive unit and two conveying chains are mounted on the conveying frame, with each chain connected to the output end of the conveying drive unit. A tray is placed on the two conveying chains. When the conveying drive unit drives the two conveying chains, the tray moves smoothly along the chains, allowing it to move to a position corresponding to the support mechanism.

[0010] In a preferred embodiment of this invention, the conveying drive unit includes a conveying drive assembly installed within a conveying frame and a chain shaft rotatably connected within the conveying frame. The output end of the conveying drive assembly is connected to the chain shaft via chain drive, and the sprocket shafts of the conveying chains are respectively connected to the chain shaft via chain drive. The conveying drive assembly drives the chain shaft to rotate via the chain, and the chain shaft then drives the sprocket shafts of the two conveying chains to rotate via the chain, thereby enabling the two conveying chains to move synchronously.

[0011] As a preferred embodiment of this utility model, the edge of the conveyor frame is provided with a rolling slider, and a longitudinal groove is provided inside the frame, with the rolling slider fitted inside the longitudinal groove. During the lifting mechanism's operation of raising and lowering the conveyor frame, the rolling slider rolls within the longitudinal groove, thereby reliably guiding the conveyor frame and ensuring smooth lifting and lowering of the conveyor mechanism.

[0012] In a preferred embodiment of this utility model, the limiting mechanism includes a limiting cylinder installed within the conveyor frame. The piston rod of the limiting cylinder is rotatably connected to a connecting rod, and the other end of the connecting rod is fixed to a rotating rod. The rotating rod is rotatably connected within the conveyor frame, and a limiting rod is fixed to the rotating rod. The limiting rod has a limiting groove that engages with the end of the material tray. The limiting cylinder drives the connecting rod to rotate, causing the limiting rod on the rotating rod to tilt upwards or downwards. When the limiting rod tilts upwards, the groove on the limiting rod blocks and limits the material tray, ensuring accurate alignment between the material tray and the support mechanism. When the limiting rod tilts downwards, the limiting rod no longer blocks the material tray, allowing it to be output from the conveyor mechanism.

[0013] In a preferred embodiment of this invention, the support mechanism includes a support cylinder rotatably mounted on the frame and a tilting shaft rotatably connected to the frame. A locking block is fixed on the tilting shaft. The piston rod of the support cylinder is rotatably connected to the locking block. A locking frame is provided on the upper edge of the material tray, and the locking block engages with the locking frame. The support cylinder drives the entire assembly of the locking block and the tilting shaft to rotate, thereby allowing the locking block to engage or disengage from the edge of the material tray.

[0014] As a preferred embodiment of this utility model, a guiding mechanism for guiding the material frame is installed on the frame. During the lifting and lowering process of the conveying mechanism, the guiding mechanism can guide the edge of the material tray to ensure reliable overlap between the material trays and prevent the material trays from tilting.

[0015] As a preferred embodiment of this utility model, the guiding mechanism includes a guide cylinder mounted on the frame, a guide plate connected to the piston rod of the guide cylinder, and a guide wheel rotatably connected to the piston rod of the guide cylinder. The guide plate and guide wheel guide the corners of the material tray, and the four sets of guiding mechanisms guide the material tray from the four corners respectively, ensuring that the material tray does not misalign during the lifting and lowering process.

[0016] The beneficial effects of this utility model are as follows: In this invention, when the material tray is conveyed by the conveying mechanism, the limiting mechanism rotates to a position protruding from the conveying mechanism, thereby blocking and limiting the material tray. At this time, after the lifting mechanism raises the conveying mechanism, the supporting mechanism rotates towards the material tray, and the end of the supporting mechanism can accurately engage with the edge of the material tray, ensuring that the material tray can be accurately lifted. When the next material tray is conveyed into place, the limiting mechanism also limits it, and the two layers of material trays can accurately overlap, ensuring reliable stacking. Similarly, when dismantling the trays, the supporting mechanism first loosens the overlapping material trays, the lifting mechanism lowers the conveying mechanism, and the limiting mechanism can accurately limit the material trays. At this time, when the supporting mechanism rotates towards the material tray, it can accurately engage with the second layer of material trays. In summary, the limiting mechanism of this invention can ensure reliable positioning of the material trays and ensure that the supporting mechanism can accurately support the material trays during the stacking and dismantling processes.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0021] like Figure 1 As shown, the automatic tray stacking and unstacking machine of this embodiment includes a frame 1, a lifting mechanism 2 installed on the frame 1, a conveying mechanism 4 for conveying trays 3 connected to the output end of the lifting mechanism 2, a rotatable support mechanism 5 for supporting trays 3 installed on the frame 1, the support mechanism 5 being located above the conveying mechanism 4, and a limiting mechanism 6 for limiting the trays 3 installed on the conveying mechanism 4; when stacking trays, the lifting mechanism 2 drives the conveying mechanism 4 to rise, and the support mechanism 5 rotates to a position engaging the edge of the trays 3 on the conveying mechanism 4; when unstacking trays, the lifting mechanism 2 drives the conveying mechanism 4 to rise, and the support mechanism 5 rotates to a position disengaging from the edge of the trays 3, and the trays 3 fall onto the conveying mechanism 4.

[0022] In this invention, when the material tray 3 is conveyed by the conveying mechanism 4, the limiting mechanism 6 rotates to a position protruding from the conveying mechanism 4, thereby blocking and limiting the material tray 3. At this time, after the lifting mechanism 2 raises the conveying mechanism 4, the supporting mechanism 5 rotates towards the material tray 3, and the end of the supporting mechanism 5 can accurately engage with the edge of the material tray 3, ensuring that the material tray 3 can be accurately lifted. When the next material tray 3 is conveyed into place, it is also limited by the limiting mechanism 6, and the two layers of material trays 3 can accurately overlap together, ensuring reliable stacking. Similarly, when dismantling the trays, the supporting mechanism 5 first loosens the overlapping material trays 3, the lifting mechanism 2 lowers the conveying mechanism 4, and the limiting mechanism 6 can accurately limit the material tray 3. At this time, when the supporting mechanism 5 rotates towards the material tray 3, it can accurately engage with the second layer of material trays 3. In summary, the limiting mechanism 6 of this invention can ensure reliable positioning of the material tray 3 and ensure that the supporting mechanism 5 can accurately support the material tray 3 during the stacking and dismantling processes.

[0023] Specifically, the lifting mechanism 2 includes a lifting power unit 21 mounted on the frame 1. The output end of the lifting power unit 21 is connected to a drive shaft 22, on which a drive sprocket is mounted. A driven sprocket is mounted at the end of the frame 1 furthest from the lifting power unit 21. A lifting chain 23 is connected between the drive sprocket and the driven sprocket, and the conveying mechanism 4 is fixed to the lifting chain 23. Driven by the lifting power unit 21, the drive shaft 22 rotates, driving the lifting chain 23 to move between the drive sprocket and the driven sprocket. The lifting chain 23 drives the conveying mechanism 4 to rise or fall, and in conjunction with the action of the support mechanism 5, achieves the stacking or unstacking of trays.

[0024] The drive shaft 22 has two drive sprockets installed at both ends and two driven sprockets. The two drive sprockets and two driven sprockets are respectively located on both sides of the conveying mechanism 4, which is fixed between two lifting chains 23. The two lifting chains 23 synchronously drive the conveying mechanism 4 to rise or fall, ensuring the smooth lifting and lowering of the conveying mechanism 4.

[0025] Specifically, the conveying mechanism 4 includes a conveying frame 41, which is disposed within the frame 1 and fixed to the output end of the lifting mechanism 2. A conveying drive unit and two conveying chains 42 are mounted on the conveying frame 41. The two conveying chains 42 are respectively connected to the output end of the conveying drive unit. The material tray 3 is placed on the two conveying chains 42. When the conveying drive unit drives the two conveying chains 42, the material tray 3 moves smoothly on the two conveying chains 42, thereby allowing the material tray 3 to move to the position corresponding to the support mechanism 5.

[0026] The conveying drive unit includes a conveying drive assembly 43 installed within the conveying frame 41 and a chain shaft 44 rotatably connected within the conveying frame 41. The output end of the conveying drive assembly 43 is connected to the chain shaft 44 via chain drive, and the sprocket shafts of the conveying chains 42 are respectively connected to the chain shaft 44 via chain drive. The conveying drive assembly 43 drives the chain shaft 44 to rotate via chain, and the chain shaft 44 then drives the sprocket shafts of the two conveying chains 42 to rotate via chain, so that the two conveying chains 42 can move synchronously.

[0027] Furthermore, the edge of the conveyor frame 41 is provided with a rolling slider 45, and a longitudinal groove 11 is provided inside the frame 1, with the rolling slider 45 fitted inside the longitudinal groove 11. During the process of the lifting mechanism 2 driving the conveyor frame 41 to rise and fall, the rolling slider 45 rolls within the longitudinal groove 11, thereby providing reliable guidance for the conveyor frame 41 and ensuring the smooth lifting and lowering of the conveyor mechanism 4.

[0028] Specifically, the limiting mechanism 6 includes a limiting cylinder 61 installed within the conveyor frame 41. The piston rod of the limiting cylinder 61 is rotatably connected to a connecting rod 62. The other end of the connecting rod 62 is fixed to a rotating rod 63, which is rotatably connected within the conveyor frame 41. A limiting rod 64 is fixed to the rotating rod 63, and the limiting rod 64 has a limiting groove that engages with the end of the material tray 3. The limiting cylinder 61 drives the connecting rod 62, which in turn drives the rotating rod 63 to rotate, causing the limiting rod 64 on the rotating rod 63 to tilt upwards or downwards. When the limiting rod 64 tilts upwards, the groove on the limiting rod 64 blocks and limits the material tray 3, ensuring that the material tray 3 is accurately aligned with the support mechanism 5. When the limiting rod 64 tilts downwards, it no longer blocks the material tray 3, allowing the material tray 3 to be output from the conveyor mechanism 4.

[0029] Specifically, the support mechanism 5 includes a support cylinder 51 rotatably mounted on the frame 1 and a tilting shaft 52 rotatably connected to the frame 1. A locking block 53 is fixed on the tilting shaft 52. The piston rod of the support cylinder 51 is rotatably connected to the locking block 53. A locking frame 31 is provided on the upper edge of the material tray 3, and the locking block 53 engages with the locking frame 31. The support cylinder 51 drives the entire assembly of the locking block 53 and the tilting shaft 52 to rotate, thereby allowing the locking block 53 to engage or disengage from the edge of the material tray 3.

[0030] Furthermore, a guide mechanism 7 is installed on the frame 1 to guide the material frame. During the lifting and lowering process of the conveying mechanism 4, the guide mechanism 7 can guide the edge of the material tray 3 to ensure that the material trays 3 can reliably overlap and prevent the material trays 3 from tilting.

[0031] The guiding mechanism 7 includes a guide cylinder 71 mounted on the frame 1. A guide plate 72 is connected to the piston rod of the guide cylinder 71, and a guide wheel 73 is rotatably connected to the piston rod of the guide cylinder 71. The guide plate 72 and the guide wheel 73 guide the corners of the material tray 3. The four sets of guiding mechanisms 7 guide the material tray 3 from the four corners respectively, ensuring that the material tray 3 does not misalign during the lifting and lowering process.

[0032] In this embodiment, both the lifting power unit 21 and the conveying drive assembly 43 are motors and reducers.

[0033] Working principle: Stacking process: The front conveyor belt transports the tray 3 to the conveying mechanism 4, which continues to transport the tray 3 until the limiting rod 64 of the limiting mechanism 6 blocks the tray 3. The lifting mechanism 2 drives the conveying mechanism 4 to rise, and the supporting mechanism 5 rotates to a position where it engages the edge of the tray 3 on the conveying mechanism 4. The lifting mechanism 2 then lowers the conveying mechanism 4, and the next tray 3 is transported to the conveying mechanism 4 and positioned by the limiting mechanism 6. The supporting mechanism 5 rotates in the opposite direction to open the upper tray 3, and the upper tray 3 overlaps with the lower tray 3. This process is repeated, and multiple trays 3 can be stacked in this way.

[0034] Disassembly process: The lifting mechanism 2 drives the conveying mechanism 4 to rise to the position of contacting the bottommost tray 3. The supporting mechanism 5 releases the tray 3, and the conveying mechanism 4 lowers by one layer. The supporting mechanism 5 rotates to support the second tray 3. The lifting mechanism 2 then lowers the conveying mechanism 4 by a certain height, separating the bottommost tray 3 from the second tray 3. After the limiting mechanism 6 lowers, the tray 3 can be output through the conveying mechanism 4. This process is repeated to disassemble multiple trays 3.

[0035] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
